PICKLEBALL PADDLE WITH WEIGHTING ASSEMBLY

Abstract

A pickleball paddle has a perimeter weighting system to improve performance characteristics and/or to provide swing weighting. The weighting system may include flexible weight strips disposed in recesses formed about a perimeter of the paddle. Alternatively, the weighting system may include slidable weights disposed in one or more channels. The weighting system may further include handle weighting to provide swing weighting. The at least one weight can have a relatively high mass, sufficient to noticeably alter CG of the paddle.

Description

TECHNICAL FIELD

This invention generally relates to pickleball equipment, and more particularly, to pickleball paddles.

BACKGROUND

A conventional pickleball paddle primarily consists of a handle and a paddle head. Players, seeking better control and/or more power, may adjust the weight distribution of the paddle. One manner is placing weighted lead tape around the edges of the paddle head. This approach requires a user to cut selected lengths of lead tape and apply them to desired locations around the paddle head. Over time, the lengths of weighted lead tape will wear and/or detach from the paddle, necessitating replacement. Consequently, using weighted lead tape to adjust the weight distribution of a pickleball paddle is overly cumbersome and time consuming. Additionally, the effective weight distribution will change over time as the weighted lead tape wears. Further, as the lead tape is replaced, the lengths and portions can be different than those previously applied to the paddle head, resulting in inconsistent weight distribution. Therefore, there is a need in the art for pickleball weight systems that maintain a precise weight distribution, and are durable while being easy to install and replace.

DETAILED DESCRIPTION

Described herein are various embodiments depicting pickleball paddles comprising a plurality of adjustable or fixed weight assemblies (hereafter alternately referred to as “the one or more weight assemblies” or “weight assemblies”). The one or more weight assemblies can give the pickleball paddle more control, durability, precision and/or power through impact than a traditional pickleball paddle. The one or more weight assemblies include a plurality of weights received by a plurality of receptacles. Additionally, the weight assemblies can provide “swing weighting” which influences how a paddle “feels” when swung. Every paddle has a swing weight, which is the horizontal MOI about an axis located 2.0 inches from the butt end of the grip. Two pickleball paddles of identical mass can have vastly different swing weights and will therefore offer substantially different feel. For example, adjusting the location of the weight assemblies to be nearer to the handle can bring the CG of the paddle closer to the handle, resulting in a paddle where the user “feels” more in control. In contrast, adjusting the weight assemblies to be nearer to the top of the paddle head raises CG, resulting in a paddle which “feels” heavier and more powerful.

A snap fit connection can be secured without the use of a tool.

An “XYZ” coordinate system of a pickleball paddle, as described herein, is based upon the geometric center of the face plate. The pickleball paddle face dimensions as described herein can be measured based on a coordinate system as defined below. The origin of the coordinate system is located at the geometric center of the face plate. The coordinate system defines an X axis, a Y axis, and a Z axis. The X axis extends through the geometric center of the face plate in the direction from a top end to a bottom end of the paddle face. The Y axis extends through the geometric center of the face plate in a direction from a left end to a right end of the pickleball paddle head. The Y axis is perpendicular to the X axis. The Z axis extends through the geometric center of the face plate in the direction from a front face plate to a rear face plate of the pickleball paddle head. The Z axis is perpendicular to both the X axis and the Y axis.

The XYZ coordinate system of the pickleball paddle head, as described herein, defines an XY plane extending through the X axis and the Y axis. The coordinate system defines XZ plane extending through the X axis and the Z axis. The coordinate system further defines a YZ plane extending through the Y axis and the Z axis. The XY plane, the XZ plane, and the YZ plane are all perpendicular to one another and intersect at the coordinate system origin located at the geometric center of the face plate. In these or other embodiments, the pickleball paddle head can be viewed from a front view when the face plate is viewed from a direction perpendicular to the XY plane. Further, in these or other embodiments, the pickleball paddle head can be viewed from a side view or side cross-sectional view when the lateral edge is viewed from a direction perpendicular to the YZ plane.

Described herein are various embodiments depicting pickleball paddles comprising a plurality of adjustable or fixed weight assemblies (hereafter alternately referred to as “the one or more weight assemblies” or “weight assemblies”). The one or more weight assemblies can give the pickleball paddle more control, durability, precision and/or power through impact than a traditional pickleball paddle. The one or more weight assemblies include a plurality of weights received by a plurality of receptacles. Additionally, the weight assemblies can provide “swing weighting” which influences how a paddle “feels” when swung. Every paddle has a swing weight, which is a measurement of how far a center of gravity (CG) is from the geometric center of the handle. Two pickleball paddles of identical mass can have vastly different swing weights and will therefore offer substantially different feel.

For example, adjusting the location of the weight assemblies to be nearer to the handle can bring the CG of the paddle closer to the handle. A CG positioned closer to the handle has a lighter feel and gives the end user more stability with greater vibrational dampening. Pickleball paddles with their mass concentrated near the handle will have a lower swing weight, making it easier to control, and are more ideal for beginners. These pickleball paddles can be considered forgiving paddles. Forgiveness can generally be thought of as the tendency for a particular paddle to yield off target shots. In general, the higher MOI a paddle has about its handle axis (or MOI_ha), the more forgiving the paddle will be. This is because paddles with high MOI_ha will have less tendency to twist with off-center impacts.

In contrast, adjusting the weight assemblies to be nearer to the top of the paddle head raises CG. A CG positioned closer to the top of the paddle head can make the swing feel heavier and give the end user greater spin and power at impact, despite the actual mass of the paddle remaining constant. Pickleball paddles with their mass concentrated further away from the handle will have a higher swing weight, deliver more power, and are typically preferred by more skilled players. These pickleball paddles can be considered performance paddles.

The overall mass of a paddle can include structural weight (i.e., the weight associated with structural components needed for durability) and discretionary mass (i.e., mass that can be strategically located throughout the paddle to achieve performance characteristics). In general, users prefer to use paddles which have an overall mass between 212.62 grams (7.5 oz) and 240.97 grams (8.5 oz). Mass properties for a large majority of the overall mass are dedicated to the core structure, face plate material and the handle. These structures typically account for anywhere between 170 grams and 227 grams of mass. Therefore, depending upon the total mass of the paddle, about 71 grams of discretionary mass may be available to achieve the desired swing weight and forgiveness. Additionally, structural components may be designed to create additional discretionary mass. An adjustable weight assembly can be implemented within the paddle to allow for the adjustability of the swing weight. A plurality of receptacles can be embedded into the paddle or positioned along the perimeter wall of the paddle for receiving a plurality of weights. Each of the plurality of receptacles can receive a weight having a particular mass such that the paddle offers a desired swing weight. The sum of the mass of the plurality of weights can be equal to the discretionary mass.

Forgiveness can generally be thought of as the tendency for a particular paddle to yield off target shots. In general, the higher MOI a paddle has about its handle axis (or MOI_ha), the more forgiving the paddle will be. This is because paddles with high MOI_ha will have less tendency to twist with off-center impacts.

To offer paddles with both high levels of forgiveness and desired swing weights, the present invention provides weight assemblies with one or more weights located to improve performance characteristics of the paddle. Each weight may be received in a receptacle. Receptacles are structures which enable weights to be securely received by the paddle head. Receptacles may take on a variety of forms and can include structures such as the channels described above, transverse sockets, edge slots, or pockets located on the paddle head.

Edge slots comprise a port located along the edge guard aligned in a direction perpendicular to the paddle z-axis. Edge slots further comprise a slot aligned with the port. Ports are openings along the exterior of the paddle which provide access to the core material.

Slots are recesses within the core material and/or edge guard material which mirror weight geometry such that the weight is securely received by the paddle. Slots can contain locking geometries such as threads, recesses, keyed portions, or similar geometries for locking weights into place.

Transverse sockets comprise ports located along the strike face or edge guard which are perpendicular to the paddle z-axis. Transverse sockets further comprise slots extending through the core material aligned with their corresponding ports. Transverse sockets may extend entirely or partially through the edge guard, face plates, and core material.

Pockets are recesses within the core material for receiving weights. Pockets may contain locking geometries similar to the locking geometries of the slots described above. Pockets may be located along the perimeter wall of the paddle such that the weight is not entirely embedded within the core material. Alternatively, pockets may be located entirely within the core material such that weights received by the core material are entirely embedded by the core material. Weights received by pockets which do not entirely embed the weight within the core material may be covered by the face plates and/or edge guard. Multiple receptacle structures may be used on the same paddle. For example, a paddle may contain transverse sockets, pockets, edge slots, and channels or any combination thereof.

The interior core 109 sits between the front face plate 110 and the rear face plate 111 (also referred to as “face plates”). The interior core 109 can resemble a honeycomb structure that can provide “feel” to the paddle and can be tuned to certain tactile properties (such as hard, soft, etc.). The honeycomb structure can comprise polypropylene cells that share sides. In some embodiments, the honeycomb structure can be made out of nylon, polymer, aluminum, or any other suitable material or combination of materials. The interior core 109 can comprise a constant thickness or a varying thickness across the interior core 109. Where the interior core 109 meets the front face plate 110 or rear face plate 111, the interior core 109 comprises a skin to allow for easy adherence to the face plates 110, 111. The skin can be made of the same material as the interior, or it can be another material, such as polyester or polycarbonate. The interior core 109 can be adhered to the face plates 110, 111 using adhesives, tapes, epoxies, mechanical fastener assemblies, and any suitable combination thereof.

The front face plate 110 and the rear face plate 111 can comprise bonding surfaces, such as grooves or raised ribbing, to aid in even and controlled adhesive distribution. In other embodiments, the interior core 109 and the face plates 110, 111 can be mechanically secured together. Additionally, the face plates do not comprise apertures that extend through the thickness of the paddle, and therefore are imperforate.

The front face plate 110 and the rear face plate 111 can be formed of any material, such as metals, polymers (e.g., thermoset, thermoplastic polyurethane, thermoplastic elastomer), composites, or any combination thereof. For example, the front face plate 110 and the rear face plate 111 can be formed, but not limited to, carbon fiber, fiberglass, steel, titanium, aluminium, graphite or any suitable combination thereof. In one embodiment, the front face plate 110 and the rear face plate 111 can be comprised of a carbon/titanium mix. The face plates 110, 111 can comprise a generally stadium-shaped form, with the right lateral wall 108 and the left lateral wall 107 generally parallel to each other and the bottom lateral wall 106 and the top lateral wall 105 whose ends are capped with semicircles of similar consistent radii.

The front face plate 110 and the rear face plate 111 can each comprise a face plate thickness. In some embodiments, the face plate thickness can be between 0.001 inches and 0.013 inches. In some embodiments the face plate thickness can be between 0.001 inches and 0.003 inches, 0.003 inches and 0.005 inches, 0.005 inches and 0.007 inches, 0.007 inches and 0.009 inches, 0.009 inches and 0.011 inches, 0.011 inches and 0.013 inches. The position of the CG depends on the face plate length and the face plate width. In some embodiments, the face plate thickness can be constant. In other embodiments, the face plate thickness can vary. In further embodiments, the front face plate thickness can be the same as the rear face plate thickness. In another embodiment, the front face plate thickness can be different from the rear face plate thickness.

Additionally, the pickleball paddle 100 may comprise an optional edge guard 134. The use of an edge guard 134 can help create a clean aesthetic appearance, while also acting as a “bumper” between the paddle 100 and the ground to increase the longevity of the paddle 100. The edge guard 134 can be located around the perimeter wall 102. In one embodiment, the edge guard 134 can cover the whole width of the perimeter wall 102 and overlap onto the face plates 110, 111. In another embodiment, the edge guard 134 can be located within a perimeter cavity, defined where the first frame component 115 meets the second frame component 116. The edge guard 134 can be one continuous piece or two or more individual pieces.

I. PICKLEBALL PADDLE WITH PERIMETER CHANNELS CONTAINING ADJUSTABLE WEIGHTS

The weighting system described herein comprises an embodiment having an adjustable mass configuration. The embodiment described herein can comprise a channel enabling a user to modify the paddle's CG and/or moment of inertia to achieve the desired performance characteristics (e.g. control, power, etc.) under various circumstances.

The first adjustable weighting system can comprise a first channel 231 defining a first channel cavity extending along a first channel axis 232, wherein the first channel axis 232 traverses at least a portion of the perimeter wall. The first channel 231 can comprise a first channel top end 238 and a first channel bottom end 239. In one embodiment, the first channel 231 can be located along the left lateral wall.

Further, the first adjustable weighting system can comprise a first adjustable weight assembly 230. The first adjustable weight assembly 230 can comprise a first weight 246 and a first fastener 245. The first adjustable weight assembly 230 can be slidably received within the first channel cavity and movable along the first channel axis 232. The first fastener 245 can be configured to fix the first weight 246 in any desired position along the first channel axis 232.

As shown in FIG. 21, the first channel 231 can comprise a first surface 233, a second surface 234, a third surface 235, a fourth surface 236, and a fifth surface 237. The five surfaces can be continuous such that the first adjustable weight assembly 230 can be slidably adjusted within the first channel 231. The first adjustable weight assembly 230 can be configured to be adjusted along the first channel 231 to any of a range of selectable positions. The position can be selected by sliding the first adjustable weight assembly 230 towards the first channel top end 238 or the first channel bottom end 239. The position of the first adjustable weight assembly 230 within the first channel 231 will adjust CG location and MOI properties, moving the first adjustable weight assembly 230 towards the first channel bottom end 239 or the first channel top end 238 will move the CG and can help control the paddle 200 through impact. In some embodiments, further described below, the fastener 245 can be configured to secure the first weight 246 within the first channel 245 to any of the selectable positions.

The fourth surface 236 can extend out across the top of the first weight 246 to help secure the first weight 246 within the first channel 231. The fourth surface 236 can comprise a first end and a second end. The first end can be located at the juncture where the fourth surface 236 extends from the second surface 234. The second end can be where the fourth surface 236 terminates. The fourth surface 236 can extend perpendicular from the first end, parallel to the first surface 233. In some embodiments, the fourth surface 236 can extend at an angle from the first end, not parallel to the first surface 233.

The fifth surface 237 can extend out across the top of the first weight 246 to help secure the first weight 246 within the first channel 231. The fifth surface 237 can extend perpendicular from the top of the third surface 235, parallel to the first surface 233. In some embodiments, the fifth surface 237 can extend at an angle from the first end, not parallel to the first surface 233. The fourth surface 236 and fifth surface 237 can extend over the first adjustable weight assembly 230 to ensure it stays within the first channel 231. The fourth surface 236 and the fifth surface 237 can be used to contain the first weight 246 within the first channel 231. Additionally, the fourth surface 236 and the fifth surface 237 can act as a guide to align the first weight 246 within the first channel 231, ensuring a secure tight fit.

The fourth surface can comprise a wall length to define how much of the first weight 246 is shown at the exterior. If a small amount of the first weight 246 is shown then the first weight 246 may not be movable. If a larger amount of the first weight 246 is shown then the first weight 246 may be movable. If all of the first weight 246 is shown then the first weight 246 may be removable. The fourth surface wall length can be measured from the first end to the second end. In some embodiments, the fourth surface wall length can vary between 0.001 inch and 0.150 inch. In some embodiments, the fourth surface wall length can vary between 0.001 inch and 0.010 inch, 0.010 inch and 0.020 inch, 0.020 inch and 0.030 inch, 0.030 inch and 0.040 inch, 0.040 inch and 0.050 inch, 0.050 inch and 0.060 inch, 0.060 inch and 0.070 inch, 0.070 inch and 0.080 inch, 0.080inch and 0.090 inch, 0.090 inch and 0.100 inch, 0.100 inch and 0.110 inch, 0.110 inch and 0.120inch, 0.120 inch and 0.130 inch, 0.130 inch and 0.140 inch, or 0.140 inch and 0.150 inch.

In an exemplary embodiment, the fourth surface wall length can be 0.105 inch. The fifth surface length and the fourth surface wall length can be symmetrical or asymmetrical along the length of the first channel.

The fourth surface can comprise a thickness to help define the height dimensions of the first weight 246. Limiting the first weight height can limit the amount of mass the first weight 246 can hold. The fourth surface thickness can be adjusted to accommodate varying width weight numbers. The fourth surface thickness can be measured from an inner fourth surface to an outer fourth surface. In some embodiments, the fourth surface thickness can vary between 0.0500 inch and 0.0725 inch.

The fifth surface thickness and the fourth surface thickness can be symmetrical or asymmetrical along the length of the first channel.

The cross-sectional geometry of the first channel 231 can comprise a generally rectangular shape, which can allow the first adjustable weight assembly 230 to slide easily within the first channel 231. In other embodiments, the cross-sectional geometry of the first channel 231 can comprise a circular, elliptical, triangular, square, octagon, or any other polygon or shape comprising at least three sides. In some embodiments, the first channel 231 shape can be symmetrical in a second surface 234 to third surface 235 direction. In some embodiments, the first channel 231 shape can be symmetrical in a first surface 233 to fourth surface 236 direction. In other embodiments, the first channel 231 shape can be asymmetrical in a second surface 234 to third surface 235 direction. In other embodiments, the first channel 231 shape can be asymmetrical in a first surface 233 to fourth surface 236 direction.

The first channel 231 can be made of any material, such as metals, plastics, polymers (e.g. thermoplastic polyurethane, thermoplastic elastomer), composites, or any combination thereof. In some embodiments, the first channel 231 can be a polymer injection molded with different quantities of a high-density material (e.g. metal powder) or materials of different densities.

The first channel 231 can comprise a first channel length C_L that defines the degree to which the first adjustable weight assembly 230 can be adjusted within the first channel 231. The first channel length C_L can be measured from the first channel bottom end 239 to the first channel top end 238 along the first surface 233. In some embodiments, the first channel length C_L can vary between 3.00 inches and 7.00 inches. In some embodiments, the first channel length C_L can vary between 3.00 inches and 3.40 inches, 3.40 inches and 3.80 inches, 3.80 inches and 4.20 inches, 4.20 inches and 4.60 inches, 4.60 inches and 5.00 inches, 5.00 inches and 5.40 inches, 5.40 inches and 5.80 inches, 5.80 inches and 6.20 inches, 6.20 inches and 6.60 inches, or 6.60 inches and 7.00inches. In an exemplary embodiment, the first channel length C_L can be 5.09 inches. In an exemplary embodiment, the first channel length C_L can be between 5.0 inches and 5.15 inches. The first channel 231 can extend from the bottom end of the left lateral wall towards the top end of the left lateral wall.

The first channel 231 can comprise a first channel depth C_D that defines the height dimensions of the first weight 246. Limiting the first weight height can limit the amount of mass the first weight 246 can hold. The first channel depth C_D can be measured from the fourth surface 236 to the first surface 233. In some embodiments, the first channel depth C_D can vary between 0.30 inch and 0.44 inch. In some embodiments, the first channel depth C_D can vary between 0.30 inch and 0.32 inch, 0.32 inch and 0.34 inch, 0.34 inch and 0.36 inch, 0.36 inch and 0.38 inch, 0.38 inch and 0.40 inch, 0.40 inch and 0.42 inch, or 0.42 inch and 0.44 inch. In an exemplary embodiment, the first channel depth can be 0.37 inch. In some embodiments, the first channel depth C_D can be constant along the first channel length C_L. In other embodiments, the first channel depth C_D can vary along the first channel length C_L. The depth of the channel can provide means for the weights to be flush with the exterior frame surface for aesthetic purposes, inset from the perimeter wall to secure the first weight 246 within the first channel 231, or extend out past the racket edge for maximum MOI potential.

The first channel 231 can comprise a first channel width C_W that defines the width dimensions of the first weight 246. Limiting the first weight width can limit the amount of mass the first weight 246 can hold. The first channel width C_W can be measured from the second surface 234 to the third surface 235. In some embodiments, the first channel width C_W can vary between 0.30 inch and 0.44 inch. In some embodiments, the first channel width C_W can vary between 0.30 inch and 0.32 inch, 0.32 inch and 0.34 inch, 0.34 inch and 0.36 inch, 0.36 inch and 0.38 inch, 0.38 inch and 0.40 inch, 0.40 inch and 0.42 inch, or 0.42 inch and 0.44 inch. In an exemplary embodiment, the first channel width C_W can be 0.38 inch. In some embodiments, the first channel width C_W can be constant along the length of the first channel 231. In other embodiments, the first channel width C_W can vary along the length of the first channel 231. A channel with a constant width can allow for weights within the channel to have infinite positions. A channel with a varied width restricts the weights within the channel to having predetermined positions.

The predetermined weight locations can be located to high MOI and/or advantageous CG placement. In one exemplary embodiment, the first channel 231 can comprise an asymmetric shape, wherein the cross-sectional shape of the first channel 231 in a first channel top end 238 to first channel bottom end 239 direction is non-uniform. The asymmetric shape of the first channel 231 can be imperative to the security of the first adjustable weight assembly 230 within the first channel 230. The asymmetric shape of the first channel 231 can allow for any number of distinct attachment points for the first weight 246. In some embodiments, the asymmetric shape of the first channel can comprise one or more distinct attachment points. In some embodiments, the asymmetric shape of the first channel can comprise one distinct attachment point, two distinct attachment points, three distinct attachment points, four distinct attachment point, five distinct attachment point, six distinct attachment points, seven distinct attachment points, or eight or more distinct attachment points. In an exemplary embodiment, the asymmetric shape of the first channel 231can allow for three distinct attachment points. Three sections of the asymmetric channel, corresponding to the first adjustable weight assembly shape, can be provided to securely fit the adjustable weight assembly 230. Thereby, the three sections of the asymmetric channel enable three positions for the first adjustable weight assembly 230 to sit within. Due to the asymmetric shape of the first channel 231, the first adjustable weight assembly 230 is unable to slide throughout the first channel 231. Rather, the first adjustable weight assembly 230 must be removed and placed in one of the three distinct attachment points.

The first weight 246 can be attached to the first channel 231 in a manner that the selected position retains the first weight 246 within the first channel 231 during use. The five surfaces 233, 234, 235, 236, 237 can be configured to include a plurality of discrete attachment locations. The plurality of discrete attachment locations can comprise various features including protruding bodies, apertures, recesses, or ports capable of receiving a fastener, notches, tabs, cutout regions, ribs, grooves, pegs, hooks, magnets, programmable magnets, or any other suitable attachment means. In one embodiment, the first surface 233 can comprise three discrete attachment locations. In one embodiment, the three discrete attachment locations each comprise features A, B, and C. Features A, B, and C can be any one of the features discussed above or any combination thereof. In one exemplary embodiment, features A, B, and C are all apertures.

In a further embodiment, the first channel can be a continuous channel located around the whole perimeter of the paddle head. A continuous channel allows the weight to be positioned in any one of an infinite number of positions around the entire perimeter wall. The ability to place the first weight 246 anywhere along the perimeter wall can improve forgiveness and performance of the paddle. The top lateral wall, the bottom lateral wall, the right lateral wall, and the left lateral wall can each contain a channel connected to one another.

In some embodiments, the first channel 231 can comprise one or more weight members 246. In some embodiments, the first channel 231 can comprise one weight, two weights, three weights, four weights, five weights, or more than five weights. The weight member 246 can comprise a weight top surface, a weight bottom surface, a weight left surface, a weight right surface, a weight front surface, and a weight back surface. Referring to FIG. 22, the weight member 246 can comprise an aperture 247 extending through the weight member 246. The aperture 247 can be located on the weight top surface and extend towards the weight bottom surface. In an exemplary embodiment, the aperture 247 extends through the weight bottom surface. The aperture 247 can comprise an aperture thread located on the interior of the aperture 247. The fastener 245 can be retained within the weight member 246 by the aperture thread. The one or more weight members 246 can be strategically positioned within the first channel 231 to achieve a desired paddle CG position and/or moment of inertia and/or right/left bias.

The one or more weight members 246 can have the same or different masses. The mass of the one or more weight members 246 can help achieve the desired characteristics by using lighter or heavier weight members 246 to manipulate the CG. In many embodiments, the mass of the weight member 246 ranges between 2.5 grams and 40.0 grams. In some embodiments, the mass of the weight member 246 can vary between 2.5 grams and 5.5 grams, 5.5 grams and 8.5 grams, 8.5 grams and 11.5 grams, 11.5 grams and 14.5 grams, 14.5 grams and 17.5 grams, 17.5 grams and 20.5 grams, 20.5 grams and 23.5 grams, 23.5 grams and 26.5 grams, 26.5 grams and 29.5 grams, 29.5 grams and 32.5 grams, 32.5 grams and 35.5 grams, or 35.5 grams and 38.5 grams. The weight member cannot have a mass less than 0.50 grams. A weight member 246 with a mass less than 0.50 grams will provide insufficient mass to affect the paddle performance in a meaningful manner.

The one or more weight members 246 can comprise a weight width W_W measured from the weight left surface to the weight right surface. In some embodiments, the weight width W_W can vary between 0.300 inch and 0.440 inch. In some embodiments, the weight width W_W can vary between 0.300 inch and 0.320 inch, 0.320 inch and 0.340 inch, 0.340 inch and 0.360 inch, 0.360 inch and 0.380 inch, 0.380 inch and 0.400 inch, 0.400 inch and 0.420 inch, or 0.420 inch and 0.440 inch. In an exemplary model, the weight width W_W can be 0.366 inch.

The one or more weight members can comprise a weight length W_L measured from the weight front surface to the weight back surface. In some embodiments, the weight length W_L can vary between 0.30 inch and 1.35 inches. In some embodiments, the weight length W_L can vary between 0.30 inch and 0.45 inch, 0.45 inch and 0.60 inch, 0.60 inch and 0.75 inch, 0.75 inch and 0.90 inch, 0.90 inch and 1.05 inches, 1.05 inches and 1.20 inches, or 1.20 inches and 1.35 inches. In an exemplary model, the weight length W_L can be 1.00 inch. In another exemplary model, the weight length W_L can be 0.50 inch.

Additionally, the one or more weight members 246 can comprise a weight height W_H measured from the weight top surface to the weight bottom surface. In some embodiments, the weight height W_H can vary between 0.300 inch and 0.500 inch. In some embodiments, the weight height W_H can vary between 0.300 inch and 0.320 inch, 0.320 inch and 0.340 inch, 0.340 inch and 0.360 inch, 0.360 inch and 0.380 inch, 0.380 inch and 0.400 inch, 0.400 inch and 0.420 inch, 0.420 inch and 0.440 inch, 0.440 inch and 0.460 inch, 0.460 inch and 0.480 inch, or 0.480 inch and 0.500inch. In an exemplary model, the weight height W_H can be 0.356 inch.

The one or more weight members 246 can be made of any material, such as metals, polymers (e.g. thermoplastic polyurethane, thermoplastic elastomer), composites, or any combination thereof. In some embodiments the one or more weight members material is chosen from a group consisting of tungsten, brass, steel, aluminum. The one or more weight members 246can be a polymer injection molded with different quantities of a high-density material (e.g. metal powder) or materials of different densities, to achieve backweights of varying mass, while maintaining the same volume. Injection molded weight members with different densities allow for a wide range of weight members with an identical volume and geometric shape.

In some embodiments, the one or more weight members 246 can comprise a generally rectangular shape. In other embodiments, the one or more weight members 246 can comprise any shape. For example, the shape of the one or more weight members 246 can comprise a circle, an ellipse, a triangle, a rectangle, an octagon, or any other polygon or shape comprising at least two curved surfaces.

The one or more weight members 246 further can comprise a weight plane 251, as shown in FIG. 23. The weight plane 251 is tangent to the weight top surface. The weight plane 251 can help define a taper angle 252. The one or more weight members 246can comprise tapered edges to allow the one or more weight members 246 to fit easily within the first channel 231. The tapered edges can comprise a taper angle 252. The taper angle 252 is measured from the weight plane down. In some embodiments, the taper angle 252 can be between 0 degrees and 70 degrees. In some embodiments, the taper angle 252 can be 0 degrees and 10 degrees, 10 degrees and 20 degrees, 20 degrees and 30 degrees, 30 degrees and 40 degrees, 40 degrees and 50 degrees, 50 degrees and 60 degrees, or 60 degrees and 70 degrees. In one exemplary embodiment, the taper angle 252 is 45 degrees.

In one embodiment, illustrated in FIGS. 16 and 17, the weight top surface can be flush with the exterior surface of the fourth surface 236. In a further embodiment, the weight top surface can connect the interior surface of the fourth surface 236, ensuring that the first weight 246 is not removable from the first channel 231.

In further embodiments, the first channel 231 can be located on the right lateral wall, the top lateral wall, or the bottom lateral wall. In other embodiments, the first channel 231 can encompass the entirety of the lateral wall or just a portion of the lateral wall. In other embodiments, the perimeter wall can comprise more than one channel 231. In some embodiments, the perimeter wall can comprise one channel, a two channels, a three channels, a four channels, a five channels or more than five channels. The one or more channels can be located on the left lateral wall, the right lateral wall, the top lateral wall, the bottom lateral wall or any combination thereof.

In an exemplary embodiment, as shown in FIGS. 13 and 15, the first channel 231 can be located along the left lateral wall and a second channel can be located along the right lateral wall. The second channel can be identical to the first channel 231.

In some embodiments, the first channel 231 can be supported by one or more ribs 243 positioned within the interior core 209 and not visible from the exterior of the paddle 200. The one or more ribs 243 protrude from the first channel 231 and can be integrally attached within the interior core 209. In some embodiments, the one or more ribs 243 are spaced from the interior surface of the frame. In some embodiments, the one or more ribs 243 can project inwardly from the base of the first channel 231 into the interior core 209. In other embodiments, the one or more ribs 243 can extend transversely across the frame opening to connect two points on the base of the first channel 231 and a second channel. The one or more ribs 243 prevent oscillation of the first channel 231 throughout impact. In one embodiment, the one or more ribs 243 are generally planar and extend in a lower end to upper end direction. The one or more ribs 243 can be made of any material, such as metals, polymers (e.g. thermoplastic polyurethane, thermoplastic elastomer), composites, or any combination thereof.

In one embodiment, shown in FIG. 18, the paddle 200 can comprise one or more ribs 243a (hereafter alternately referred to as “the ribs”) having a triangular shape which extend from the base of the one or more channels and project inwardly into the interior core 209. In an alternative embodiment, shown in FIG. 19, the ribs 243b can each comprise a rectangular shape. Further, the ribs 243 may comprise a shape selected from a group consisting of circular, ovoid, asymmetric, and any other shape. In some embodiments, the one or more ribs 243 can comprise the same shapes. In other embodiments, the ribs 243 can comprise different shapes.

The ribs 243 can provide increased thickness on the base of the channel(s) to provide support, increase rigidity, and reduce vibrations. In another embodiment, the paddle can comprise one or more ribs 243 which extend transversely across the frame opening to connect two points on the base of the channel. The ribs can further comprise a plurality of shapes including rectangular (shown in FIG. 19), triangular, circular, ovoid, asymmetric, or any other shape. The ribs can provide support, increase rigidity, and reduce vibrations to the channel(s). The ribs can further provide support, increase rigidity, and reduce vibrations to the entire frame structure of the paddle.

The one or more adjustable weight assemblies can be placed at their respective channel bottom ends to improve forgiveness. Moving CG closer towards the handle increases control during play, allowing the user to feel more in control, resulting in a more forgiving paddle.

Alternatively, the one or more adjustable weight assemblies can be placed at their respective channel top ends to improve performance. Moving CG closer towards the upper end of the paddle increases power through impact, resulting in high performance benefits.

II. PICKLEBALL PADDLES WITH RECESSED WEIGHT

The paddle 400 can comprise an exterior frame surface having one or more recesses for receiving weights, thereby to distribute mass around the paddle to improve one or more performance characteristics. For example, shown in FIGS. 24-33, the exterior frame surface can comprise discrete recesses 431 sized to receive the weighted strips 432. The distribution of mass around the periphery edge affects numerous properties, including swing weight, recoil weight, and twist weight. Different placements of weight can alter feel, performance, and control. In one example, adding weight to the paddle upper end will increase swing weight and recoil weight with minimal effect on twist weight, giving the paddle a heavier feel and greater tactile response at impact. In another example, adding weight on the left lateral wall or the right lateral wall, below the balance point, can increase twist weight without affecting swing weight and recoil weight. Still further, adding weight on the two upper end junctures, where the left lateral wall and the right lateral wall meet the top lateral wall, can increase swing weight without affecting recoil weight and twist weight. In addition to distributing mass, the weighted strips can increase durability by protecting the paddle periphery 402. For example, the weighted strips can be comprised from a material that can be resistant against scratches and dents that could happen from dropping the paddle or hitting it against the ground.

The discrete recess 431 can be comprised of a recess base wall 450, a recess first wall 451, a recess second wall 452, a recess third wall 453, and a recess fourth wall 454, as shown in FIGS. 24 and 25. The weighted strips 432 can comprise a strip bottom surface and a strip exterior surface 449. When the weighted strip 432 is placed within the discrete recess 431, the strip bottom surface can contact the recess base wall 450. The weighted strips 432 may be retained in the recess by friction alone, or with adhesive, mechanical fasteners, a double-sided very high bond strength foam tape (VHB), press fit, snap fit, or any other suitable methods. In one embodiment, the weighted strips 432 can be held in by adhesive alone. In this embodiment, the weighted strips 432 can be removed but cannot be reused. In a further embodiment, the weighted strips 432 can be held in by frictional forces. In this embodiment, the weighted strips 432 can be both removable and reusable.

The discrete recess 431 can have a peripheral shape that conforms to and secures the weighted strips 432 to the paddle 400. In many embodiments, the recess first wall 451, recess second wall 452, recess third wall 453, and recess fourth wall 454 cooperate to form a linear segment. In some embodiments, the recess first wall 451, recess second wall 452, recess third wall 453, and/or recess fourth wall 454 cooperate to form a complex geometry including a linear segment and a curved segment. The curved segment 456 can form an undercut 457 to better secure within the discrete recess 431. The undercut 457 facilitates removal and reuse of the weighted strips 432 without the use of an adhesive.

Additionally or alternatively, a cover may be provided to secure the weighted strips 432 within the discrete recesses 431. For example, the cover can be comprised of a cover interior surface, a cover exterior surface opposite the cover interior surface, and in some embodiments a cover tab/s. The cover tab/s can be parallel with the cover exterior surface geometry. In other embodiments, the cover tab/s can be perpendicular with the cover exterior surface geometry. The cover can be placed near the recess third wall 453 and/or the recess fourth wall 454. The cover can be attached by the tabs via adhesive. The cover can extend out over the weighted strips 432 as an added way to secure the weighted strips 432 within the discrete recess 431. The cover can follow the geometry of the discrete recess 431. In other embodiments, the cover can deviate from the discrete recess 431 geometry.

In a further embodiment, the discrete recess 431 can comprise an extrusion 460 extending from the recess base wall 450 to help line up the weighted strip 432 within the discrete recess 431. The extrusion 460 can terminate in line with the paddle periphery 402. The weighted strips 432 can comprise a corresponding aperture 461 with a geometry complementary to that of the extrusion 460 to ensure the weighted strip 432 is centered within the discrete recess 431. As shown in FIG. 27, the extrusion 460 and corresponding aperture 461 can be circular in shape. In other embodiments, the extrusion 460 and corresponding aperture 461 can be annular, elliptical, or similar shape.

In an additional embodiment, the discrete recesses 431 can comprise a cutout 462 designed to help remove the weighted strips 432 from the discrete recess 431. The cutout 462 can be comprised of a cutout base wall, a cutout first wall, a cutout third wall opposite the cutout first wall, and a cutout second wall joining the cutout first wall and the cutout third wall together. As shown in FIG. 28, the cutout 462 can be cut into the recess third wall 453. In other embodiments it can be cut into the recess third wall and/or the recess fourth wall 454, and be wide enough for a small tool (something will a flat surface, similar to a flat head screwdriver) to slide in and under the weighted strip 432 in order to remove it.

The number and location of the discrete recess 431 is selected to provide desired weight distribution options. In many embodiments, the paddle periphery 402 can define three or more discrete recesses 431. In one exemplary embodiment, the paddle 400 can comprise five discrete recesses 431. A first discrete recess located along the top lateral wall 405, a second discrete recess 431 at the left top transition, a third discrete recess 431 at the right top transition, a fourth discrete recess 431 at the left bottom transition, and a fifth discrete recess 431 at the right bottom transition. In a further embodiment, as shown in FIG. 32, the paddle 400 can comprise four discrete recesses 431. Including, a first discrete recess 431 located at the left top transition, a second discrete recess 431 at the right top transition, a third discrete recess 431 at the left bottom transition, and a fourth discrete recess 431 at the right bottom transition. In some embodiments, the weighted strips 432 can sit flush within the discrete recesses 431, such that the paddle periphery 402 will be level with the strip exterior surface 449. In other embodiments, the weighted strips 432 may protrude slightly outwards, such that the strip exterior surface 449 sits above the paddle periphery 402. In many embodiments, the weighted strips 432 can be positioned in one or more of several distinct locations provided by the discrete recesses 431.

In some embodiments, each weighted strip 432 can be a thin, elongate, component that is pliant to conform to the contour of the discrete recess 431 in which it is disposed. In some embodiments, the weighted strip 432 can be disposed in a substantially linear discrete recess 431. In other embodiments, the weighted strip 432 can be disposed in a discrete recess 431 having one or more arcuate portions.

Some materials that can be used for the weighted strips 432 are less pliant and therefore more difficult to conform to the curved surfaces in the recess. To improve flexibility of these materials, thinned regions may be provided in the weighted strips 432 to better conform the weighted strips 432 to the transition regions of the paddle 400. In some embodiments, the weighted strips 432 may comprise thinned regions 463 at spaced intervals across the weighted strips 432 in order to promote bending. The thinned regions 463 can be grooves across the weighted strip 432. In some embodiments, the weighted strips 432 can comprise 1 groove, 2 grooves, 3 grooves, 4 grooves, 5 grooves, or more than 5 grooves. In one embodiment, as illustrated in FIG. 29, the weighted strips 432 can comprise 3 grooves spaced equally apart along the weighted strips 432. In another embodiment, the weighted strips 432 can comprise 2 grooves spaced equally apart along the weighted strips 432. In embodiments with three or more grooves, the grooves may be spaced equally apart, or the grooves may be concentrated in a particular area, for example a central area, in order to promote bending.

In one embodiment, the weighted strips 432 can be comprised of multiple distinct materials to provide a desired overall weight, flexibility, or other physical property. The different materials can be separated into multiple distinct layers each having a different density. For example, the multi-piece weighted strips can comprise a low density material and a high density material. In one embodiment, the multi-piece weighted strips can comprise a three-piece design. The first layer can be comprised of a low density material; the second layer can be comprised of a high density material; and the third material can be comprised of a low density material. The multi-piece weighted strips can allow for further user customization. In one embodiment, the left side of the weighted strip 432 can be a first material, and the right side of the weighted strip can be a second material. The second material is different from the first material. In another embodiment, the weighted strip 432 can be layered vertically, meaning the bottom surface of the weighted strip 432 is comprised of a first material, and the top surface of the weighted strip 432 can be comprised of a second material. The second material is different from the first material. In a further embodiment, the thinned regions 463 can correspond to changes in the material of the weighted strips.

The discrete recesses 431 defined above, and as shown in FIGS. 24 and 25, can comprise a recess length. The recess length can determine how much of a weighted strip 432 can be put within the discrete recess 431, resulting in different masses being placed into differently sized discrete recesses 431. In some embodiments, the recess length can be between 2.5 inches to 4.5 inches. In some embodiments, the recess length can be between 2.5 inches to 2.7 inches, 2.7 inches to 2.9 inches, 2.9 inches to 3.1 inches, 3.1 inches to 3.3 inches, 3.3 inches to 3.5 inches, 3.5 inches to 3.7 inches, 3.7 inches to 3.9 inches, 3.9 inches to 4.1 inches, 4.1 inches to 4.3 inches, or 4.3 inches to 4.5 inches. In an exemplary embodiment, the recess length is 3.5 inches.

The discrete recesses 431 can comprise a recess depth. The recess depth can determine how much of the weighted strip 432 protrudes above the exterior frame surface, which can affect whether the weighted strips 432 act as a “bumper” or not. In some embodiments, the recess depth can be between 0.015 inch to 0.035 inch. In some embodiments, the recess depth can be between 0.015 inch to 0.018 inch, 0.018 inch to 0.021 inch, 0.021 inch to 0.024 inch, 0.024 inch to 0.027 inch, 0.027 inch to 0.030 inch, 0.030 inch to 0.033 inch, or 0.033 inch to 0.035 inch. In an exemplary embodiment, the recess depth is 0.025 inch.

The discrete recesses 431 can comprise a recess width. The recess width can determine how much of a weighted strip 432 can be put within the discrete recess 431, resulting in different masses being placed into differently sized discrete recesses 431. In some embodiments, the recess width can be between 0.20 inch to 0.40 inch. In some embodiments, the recess width can be between 0.20 inch to 0.23 inch, 0.23 inch to 0.26 inch, 0.26 inch to 0.29 inch, 0.29 inch to 0.32 inch, 0.32 inch to 0.35 inch, 0.35 inch to 0.38 inch, or 0.38 inch to 0.40 inch. In an exemplary embodiment, the recess width is 0.34 inch.

The undercut 457 can extend out over the weighted strips by an undercut distance and contact the exterior surface of the weighted strips 432. The undercut distance can be defined by the curved segment in the recess wall. In some embodiments, the undercut distance can be between 0.5% to 70% of the weighted strips. In some embodiments, the undercut can extend over the weighted strips 432 and cover between 0.5% and 5%, 5% and 10%, 10% and 15%, 15% and 20%, 20% and 25%, 25% and 30%, 30% and 35%, 35% and 40%, 40% and 45%, 45% and 50%, 50% and 55%, 55% and 60%, 60% and 65%, or 65% and 70% of the weighted strips 432.

The undercut 457 can extend around the entirety of the discrete recess 431 creating a full 360° undercut. In some embodiments, the undercut 457 can extend around the discrete recess 431 between 30° and 360°. In some embodiments, the undercut 457 can extend around the discrete recess 431 greater than 30°, greater than 60°, greater than 90°, greater than 120°, greater than 150°, greater than 180°, greater than 210°, greater than 240°, greater than 270°, greater than 300°, or greater than 330°. In some embodiments, the undercut 457 can extend discontinuously around the discrete recess 431. In other embodiments, the undercut 457 can extend only partially around the discrete recess 431. In these embodiments, the undercut 457 can be located on the side closest to the front face plate, the side closest to the back face plate, and/or on the curved transitions between the two sides.

The cutout 462 can comprise a cutout width measured between the cutout first wall and the cutout third wall. In some embodiments, the cutout width can be between 0.01 inch to 0.20 inch. In some embodiments, the cutout width can be between 0.01 inch to 0.04 inch, 0.04 inch to 0.07 inch, 0.07 inch to 0.10 inch, 0.10 inch to 0.13 inch, 0.13 inch to 0.16 inch, or 0.16 inch to 0.20 inch.

In some embodiments, the weighted strips 432 can comprise a weighted strip length WS_L. The weighted strip length WS_L can alter how much mass is able to be used within the weighted strip 432. As shown in FIG. 5, the weighted strip length WS_L can be taken from an upper end to a lower end. The weighted strip length WS_L can be between 2.5 inches and 4.5 inches. In some embodiments, the weighted strips length WS_L can be between 2.5 inches and 2.6 inches, 2.6 inches and 2.7 inches, 2.8 inches and 2.9 inches, 2.9 inches and 3.0 inches, 3.0 inches and 3.1 inches, 3.1 inches and 3.2 inches, 3.2 inches and 3.3 inches, 3.3 inches and 3.4 inches, 3.4 inches and 3.5 inches, 3.5 inches and 3.6 inches, 3.6 inches and 3.7 inches, 3.7 inches and 3.8 inches, 3.8 inches and 3.9 inches, 3.9 inches and 4.0 inches, 4.0 inches and 4.1 inches, 4.1 inches and 4.2 inches, 4.2 inches and 4.3 inches, 4.3 inches and 4.4 inches, or 4.4 inches and 4.5 inches. In some embodiments, the weighted strip length WS_L can be equal. In other embodiments, the weighted strips 432 can have different lengths. In an exemplary embodiment, the weight strips 432 are of equal length, with the length being 3.5 inches.

In some embodiments, the weighted strips 432 can comprise a thickness. The thickness can alter how much mass is able to be used within the weighted strip 432. The thickness can be measured from the strip bottom surface to the strip exterior surface. The thickness of the weighted strips can be between 0.0125 inch and 0.1125 inch.

In some embodiments, the weighted strips 432 can comprise a weighted strip height WS_H. As shown in FIG. 33, the weighted strip height WS_H can be measured from a left edge to a right edge. The weighted strip height WS_H can be between 0.0125 inch and 0.025 inch, 0.025 inch and 0.0375 inch, 0.0375 inch and 0.05 inch, 0.05 inch and 0.0625, 0.0625 inch and 0.0750 inch, 0.0750 inch and 0.0875 inch, 0.0875 inch and 0.1 inch, or 0.1 inches and 0.1125 inch.

The weighted strips 432 can further comprise a weighted strip hardness. Different weighted strip hardnesses can affect the mass of the weighted strip 432, as well as the durability of the weighted strip 432 acting as a “bumper.” In some embodiments, the weighted strip hardness can be between 55 to 99 Shore A. In other embodiments, the weighted strip hardness can be between 35 to 80 Shore D. In other embodiments, the weighted strip hardness can be between 35 Shore to 40 Shore, 40 Shore to 45 Shore, 45 Shore to 50 Shore, 50 Shore to 55 Shore, 55 Shore to 60 Shore, 60 Shore to 65 Shore, 65 Shore to 70 Shore, 70 Shore to 75 Shore, or 75 Shore to 80 Shore. In an exemplary embodiment, the weighted strip hardness can be 60 Shore A. In another exemplary embodiment, the weighted strip hardness can be 45 Shore D. In a further exemplary embodiment, the weighted strip hardness can be 70 Shore D. Weighted strips 432 of these hardnesses can be sufficiently flexible to conform to the contours of the discrete recesses formed in the paddle periphery 402.

The weighted strips 432 can be characterized by a ratio of a thickness of the weighted strip relative to a width of the weighted strip. The ratio between the thickness of the weighted strips 432 and the width of the weighted strips 432 can be between 0.1 and 0.9. In some embodiments, the ratio between the thickness of the weighted strips 432 and the width of the weighted strips can be between 0.1 and 0.2, 0.2 and 0.3, 0.3 and 0.4, 0.4 and 0.5, 0.5 and 0.6, 0.6 and 0.7, 0.7 and 0.8, or 0.8 and 0.9.

In some embodiments, the weighted strips 432 can comprise a mass between 0.1 grams and 21.1 grams. In some embodiments, the weighted strips 432 can comprise a mass between 0.1 grams to 2.1 grams, 2.1 grams to 4.1 grams, 4.1 grams to 6.1 grams, 6.1 grams to 8.1 grams, 8.1 grams to 10.1 grams, 10.1 grams to 12.1 grams, 12.1 grams to 14.1 grams, 14.1 grams to 16.1 grams, 16.1 grams to 18.1 grams, or 18.1 grams to 21.1 grams. In some embodiments, the weighted strips 432 can weigh the same. In other embodiments, the weighted strips 432 can have different masses. Changing the mass of the weighted strips 432 allows for customization of the swing weight, recoil weight, spin weight, and twist weight.

The shape of the discrete recesses 431 can be, but is not limited to, an obround or “pill shape”, which consists of two generally parallel side walls connected by semi-circular ends. The shorter sides can also be referred to as transition regions. While the shape of the weighted strips 432 can also be obround, other shapes may be used. This shape makes it easier to align the weighted strips 432 correctly on the paddle periphery 402. Shape customization can also be a possibility, subject to the thickness of the paddle 400.

The weighted strips 432, as shown in FIGS. 26-29, can be made of any material, such as metals (e.g. aluminum, stainless steel), polymers (e.g. thermoplastic polyurethane (TPU), thermoset polyurethane, thermoplastic elastomer (TPE), polyether block amide (marketed by Arkema as PEBAX®), composites, synthetic foams, cork or any combination thereof. The weighted strips 432 can use tungsten, other high-density materials (e.g. metal powder) or materials from different densities, to achieve weighted strips 432 of varying mass, while maintaining the same volume. In one exemplary embodiment, the weighted strips 432 can be comprised out of a TPE material mixed with tungsten powder. In another exemplary embodiment, the weighted strips 432 can be comprised of a TPU material mixed with tungsten powder. In a further exemplary embodiment, the weighted strips 432 can be comprised of polyether block amide mixed with tungsten powder. In various embodiments, the amount of tungsten powder can vary to allow the weighted strips 432 to have various masses and densities.

The weighted strips 432 can customize mass properties of the paddle 400 to achieve desired feel, power and/or control. In other embodiments, the weighted strips 432 can be used as “bumpers” to protect the paddle periphery 402 from damage, such as when the paddle contacts ground or a teammates' paddle.

The weight strip may comprise a color that matches or contrasts with the surrounding frame, thereby providing a desired aesthetic effect. In embodiments where the weight strip has a contrasting color, the juxtaposed color scheme may help a user locate the weight strip for removal and/or replacement.

In some embodiments, two or more weight strips may be disposed in a single recess. For example, two or more weight strips may be arranged laterally, with each weight strip extending along the entire length of the recess. In other examples, two or more weight strips may be axially aligned along the length of the recess, with each weight strip having a length that is a fraction of the recess length. Still further, in some embodiments, weight strips having different densities may be disposed in a recess, or each recess may receive a weight strip having a different density.

The ability to customize mass distribution can lead to paddles being tailored to the user and creating a more enjoyable playing experience. The distribution of mass around the periphery edge affects numerous properties, including swing weight, recoil weight, and twist weight. Different combinations of weight placement can alter feel, performance and control. Adding weight to the paddle upper end will increase swing weight and recoil weight without having a big effect on twist weight, this can result in a paddle that feels heavier with a greater impact feel. Adding weight on the left lateral wall or the right lateral wall, below the balance point, can increase twist weight without affecting swing weight and recoil weight. Adding weight on the two upper end junctures, can increase swing weight, without affecting recoil weight and twist weight.

III. PICKLEBALL PADDLES WITH SCREW-FIT HANDLE WEIGHT ASSEMBLY

In a screw-fit handle weighting embodiment, the butt end of the handle is configured to support and enclose a screw-fit handle weight assembly. Placing weight at the butt end lowers the swing weight of the paddle while increasing the recoil weight. Lowering the swing weight can make the paddle feel lighter while giving the player a better feel for control. Further, providing a screw-fit attachment increases ease of manufacturing while facilitating changing weight to suit the player's needs. FIGS. 34-36 illustrate an embodiment of the golf club head 500 that incorporates one or more embodiments of the weighting assemblies 100, 200, 300, 400, 600, 700, 800, 900 disclosed herein.

The butt end of the handle is configured to releasably secure the screw-fit handle weight assembly. For example, the butt end can comprise a base wall having an interior surface, an exterior surface, and an aperture extending through the exterior surface to the interior surface. The aperture can comprise receiving walls that project from the base wall interior surface. The receiving walls can comprise exterior surfaces facing toward handle peripheries and interior surfaces facing toward the aperture. The interior surfaces can comprise threads to support a screw-fit handle weight assembly described in greater detail below.

The butt end of the handle further comprises a plurality of side walls having a top edge that project from an outer perimeter of the base wall exterior surface to form a recess in the butt end of the handle. The recess comprises a recess depth, measured from a top edge of the plurality of sidewalls down to the base wall exterior surface. In some embodiments, the recess depth can be between 0.055 inch to 0.115 inch. In some embodiments, the recess depth can be between 0.055inch to 0.060 inch, 0.060 inch to 0.065 inch, 0.065 inch to 0.070 inch, 0.070 inch to 0.075 inch, 0.075 inch to 0.080 inch, 0.080 inch to 0.085 inch, 0.085 inch to 0.090 inch, 0.090 inch to 0.095 inch, 0.095 inch to 0.100 inch, 0.100 inch to 0.105 inch, 0.105 inch to 0.110 inch, or 0.100 inch to 0.115 inch. In an exemplary embodiment, the recess depth is 0.085 inch.

A handle weight assembly can threadedly attach to the butt end to adjust weight located at a bottom of the paddle. For example, the handle weight assembly can attach to the receiving walls, extend through the aperture, couple to the base wall exterior surface, and sit within the recess on the butt end of the handle. The handle weight assembly can be comprised of an end cap housing 530 and a weighted screw 531, as shown in FIGS. 34-36. The use of an end cap can prevent ingress of external objects (e.g., water, dust, sunscreen, etc.) that may otherwise collect within the handle during swinging, dropping, carrying, or any other suitable use of the paddle, and which can cause rattling within the handle. The end cap housing 530 and weighted screw 531 are removably attached to the butt end as a unit. Multiple handle weight assemblies may have different weights, colors, shapes, and designs, which allow the paddle to be customized.

The end cap housing 530 can be made of any material, such as metals (e.g., aluminum, stainless steel), polymers (e.g., nylon, acrylonitrile butadiene styrene (ABS), polypropylene, high density polyethylene), composites, synthetic foams, cork, or any combination thereof. In one exemplary embodiment, the end cap housing 530 can be comprised of a nylon/aluminum mix. The nylon/aluminum mix reduces the mass of the housing, thereby increasing discretionary mass to be used elsewhere, such as within the weighted screw 531.

The end cap housing 530 can include a circular disk 534 for limiting insertion and providing a surface for a tool. The circular disk 534 further comprises a disk top surface 536 and a disk bottom surface 537, as shown in FIG. 34. The disk top surface 536 additionally can comprise a central recess 545 and two perimeter recesses 546 to receive an end cap tool 529, allowing the end cap housing 530 to be attached to or removed from the handle. The two perimeter recesses 546 can be located near a periphery of the disk top surface 536. The two perimeter recesses 546 can comprise a perimeter recess depth. In some embodiments, the perimeter recess depth can be between 0.03 inch to 0.15 inch. In some embodiments, the perimeter recess depth can be 0.03 inch to 0.04 inch, 0.04 inch to 0.05 inch, 0.05 inch to 0.06 inch, 0.06 inch to 0.07 inch, 0.07 inch to 0.08 inch, 0.08 inch to 0.09 inch, 0.09 inch to 0.10 inch, 0.10 inch to 0.11 inch, 0.11 inch to 0.12 inch, 0.12 inch to 0.13 inch, 0.13 inch to 0.14 inch, or 0.14 inch to 0.15 inch. The central recess can comprise a central recess depth. The central recess depth can be the same as the perimeter recess depth. In an exemplary embodiment, the central recess depth is 0.01 inch.

The circular disk 534 can comprise a circular disk height, measured from the disk top surface 536 to the disk bottom surface 537. The circular disk height can be equivalent to the recess depth, less than the recess depth, or greater than the recess depth. Therefore, the circular disk 534 can be flush with top edge of the recess sidewalls, sit below the top edge of the recess sidewalls, or protrude out from the top edge of the recess sidewalls when the handle weight assembly is threadedly attached to the butt end of the handle. In some embodiments, the circular disk height can be between 0.055 inch to 0.115 inch. In some embodiments, the circular disk height can be between 0.055 inch to 0.060 inch, 0.060 inch to 0.065 inch, 0.065 inch to 0.070 inch, 0.070 inch to 0.075 inch, 0.075 inch to 0.080 inch, 0.080 inch to 0.085 inch, 0.085 inch to 0.090 inch, 0.090inch to 0.095 inch, 0.095 inch to 0.100 inch, 0.100 inch to 0.105 inch, 0.105 inch to 0.110 inch, or 0.100 inch to 0.115 inch. In an exemplary embodiment, the circular disk height is 0.085 inch.

The end cap housing 530 can further include a cylindrical rod 535 for enclosing the weighted screw 531 and providing a means for threadedly attaching the handle weight assembly to the butt end of the handle. The cylindrical rod 535, as shown in FIG. 35, can project from the disk bottom surface 537. The cylindrical rod 535 can comprise a rod top surface 538, a plurality of wings 539 that are complementary to the threading of the receiving walls, and a screw bore hole that is recessed away from the rod top surface 538 towards the disk bottom surface 537. The screw bore hole can be threaded or unthreaded and may be configured to receive the weighted screw 531. A tool, such as a torque-limiting tool, can be used to removably attach the weighted screw 531 to the end cap housing 530. The tool can be similar, but not limited to, a screwdriver or an allen key.

The cylindrical rod 535 can comprise a rod height, measured from the rod top surface 538 to the disk bottom surface 537. In some embodiments, the rod height can be between 0.30 inch to 1.10 inches. In some embodiments, the rod height can be between 0.30 inch to 0.40 inch, 0.40 inch to 0.50 inch, 0.50 inch to 0.60 inch, 0.60 inch to 0.70 inch, 0.70 inch to 0.80 inch, 0.80 inch to 0.90 inch, 0.90 inch to 1.00 inch, or 1.00 inch to 1.10 inch. In an exemplary embodiment, the rod height is 0.50 inch. The rod height can vary to allow weighted screws of different masses to fit securely within the cylindrical rod 535.

The end cap tool 529, as shown in FIG. 36, can be used for creating a mechanical interference fit between the handle weight assembly and the receiving walls. In operation, the end cap tool 529 can be placed upon the disk top surface 536 and rotated until the handle weight assembly is tightly secured to the butt end of the handle. Similarly, the end cap tool 529 can be used for detaching the end cap housing 530 from the handle of the pickleball paddle.

The end cap tool 529 can comprise an upper end 529a that a user can grip and a lower end 529b opposite the upper end 529a that can engage with a disk top surface. The end cap tool lower end 529b can comprise a cylindrical body and an engagement surface. The engagement surface can comprise a profile that is complementary to the geometry located on the disk top surface 536. In one exemplary embodiment, the end cap tool lower end geometry can comprise a central projection and two perimeter projections 544 having a shape complementary to the central recess 545 and two perimeter recesses 546. The end cap tool upper end 529a can comprise a hexagonal body. All edges of the hexagonal body can be rounded to ensure an ergonomic feel for the user. The shape of the end cap tool upper end 529a can be any polygonal shape comprises at least three sides to ensure the user can grip and turn the tool when engaged with the end cap housing 530. These shapes can include triangles, rectangles, quadrilaterals, pentagons, hexagons, or any other suitable shape. The perimeter projections 544 can be located closer to the periphery of the engagement surface. The perimeter projections 544 can comprise a perimeter projection height. In some embodiments, the perimeter projection height can be between 0.03 inch to 0.15 inch. In some embodiments, the perimeter projection height can be 0.03 inch to 0.04 inch, 0.04 inch to 0.05 inch, 0.05 inch to 0.06 inch, 0.06 inch to 0.07 inch, 0.07 inch to 0.08 inch, 0.08 inch to 0.09 inch, 0.09 inch to 0.10 inch, 0.10 inch to 0.11 inch, 0.11 inch to 0.12 inch, 0.12 inch to 0.13 inch, 0.13 inch to 0.14 inch, or 0.14 inch to 0.15 inch. In an exemplary embodiment, the perimeter projection height is 0.10 inch. The central projection can comprise a central projection height, which can be the same as the perimeter projection height. In an exemplary embodiment, the central projection height is 0.01 inch. In one embodiment, the height that the geometry projects from the engagement surface can match the depth of the recesses on the disk top surface 536 to make sure that the surfaces are flush with each other providing a secure fit. In other embodiments, the height that the geometry projects from the engagement surface can be different than the depth of the recesses on the disk top surface 536.

The end cap tool 529 further can comprise an end cap tool height, measured from the perimeter/central projections upwards to an upper end of the end cap tool 529. In some embodiments, the end cap tool height can be between 0.80 inch to 1.50 inch. In some embodiments, the end cap tool height can be between 0.80 inch to 0.90 inch, 0.90 inch to 1.00 inch, 1.00 inch to 1.10 inches, 1.10 inches to 1.20 inches, 1.20 inches to 1.30 inches, 1.30 inches to 1.40 inches, or 1.40 inches to 1.50 inches. In an exemplary embodiment, the end cap tool height is 1.10 inches.

Additionally, the end cap tool 529 can comprise an end cap tool width, measured between the two furthest points away from a geometrical center of the end cap tool upper end 529a. In some embodiments, the end cap tool width can be between 1.00 inch to 2.00 inches. In some embodiments, the end cap tool width can be between 1.00 inch to 1.10 inches, 1.10 inches to 1.20 inches, 1.20 inches to 1.30 inches, 1.30 inches to 1.40 inches, 1.40 inches to 1.50 inches, 1.50 inches to 1.60 inches, 1.60 inches to 1.70 inches, 1.70 inches to 1.80 inches, 1.80 inches to 1.90 inches, or 1.90 inches to 2.00 inches. In an exemplary embodiment, the end cap tool width can be 1.70 inches. The end cap tool width and the end cap tool height should be large enough to allow an average person to comfortably grip the handle, but not so large that it becomes cumbersome to use and/or carry around.

The weighted screw 531 can be removably attached, allowing for screws of different masses to be switched in and out as desired.

In one exemplary embodiment, the weighted component 731 material can be chosen from the group consisting of titanium, aluminum, steel, tungsten, titanium alloy, aluminum alloy, steel alloy and tungsten alloy.

In one embodiment, as shown in FIG. 43, the handle weight assembly is removable. A tool receiving cavity 750 can be recessed into a side surface of the hexagonal disk 734, allowing for a tool (not shown, but similar to a flat head screwdriver) to pry the end cap housing 730 out. The tool receiving cavity 750 can comprise a receiving depth. The receiving depth needs to be large enough for a majority of a tool to enter the tool receiving cavity 750, but small enough so as to not encompass the entirety of the hexagonal disk 734. In some embodiments, the receiving depth can be between 0.175 inch to 0.375 inch. In some embodiments, the receiving depth can be between 0.175 inch to 0.195 inch, 0.195 inch to 0.215 inch, 0.215 inch to 0.235 inch, 0.235 inch to 0.255 inch, 0.255 inch to 0.275 inch, 0.275 inch to 0.295 inch, 0.295 inch to 0.315 inch, 0.315 inch to 0.335 inch, 0.335 inch to 0.355 inch, or 0.355 inch to 0.375 inch. In an exemplary embodiment, the receiving depth is 0.275 inch.

In a further embodiment, as shown in FIG. 45, a paddle 800 comprising an interior core 809, a face plate 810, and a handle weight assembly can include material 840 that is inserted or injected into the handle 820 to provide further counter balancing and give the player a better feel for control. The material 840 can be made from epoxy, hotmelt, foam, tape, composite, tungsten, any other suitable polymer material, or any other suitable viscous material. The material 840 may be positioned at infinite locations within the handle 820 to allow for player customization. In one embodiment, the material 840 can partially fill the handle 820. In another embodiment, the material 840 can substantially fill the handle 820. The player can choose the material type and placement before assembly is completed to tailor the paddle 820 to the player's needs.

The use of a handle weight assembly within a paddle can provide counter balancing for a performance driven paddle. Counterbalancing a paddle can enhance the playability of a paddle. The distribution of weight feels more equal when a paddle has counter weighting, resulting in a paddle that feels lighter than a paddle with just upper end weighting. Additionally, the use of a handle weight assembly can allow a user to increase the overall mass of the paddle without affecting the twist weight and/or motion of the paddle throughout the swing.

VI. PICKLEBALL PADDLES WITH WEIGHTING ASSEMBLIES HAVING A WEIGHTED FACE PLATE

A pickleball paddle 900 having an interior core 909, according to aspects of the present invention, can further comprise a weighting assembly having a head 901 with discrete weighted portions 930 located on the face plate 910. The pickleball paddle 900 can comprise the weighted face alone or in combination with any of the weighting assemblies described above. The weighted portions 930 at certain locations on the face plate 910 such as, but not limited to, the face center, the upper end, or the lower end, redistributes relative mass properties to influence MOI and dampens vibrations.

Weighted portions 930 near the upper end of the paddle generates high power and ball speed imparted at impact. However, this comes at the cost of stability near the lower end, where a player holds the handle 920, and can thereby lower accuracy. A controlled weighting on the face alone, and not the periphery, improves the ball speed and power on return without a significant loss of stability.

The weighted portions 930 can be defined by an increased amount of material, or thickness, of the face plate 910 at particular locations. The face plate 910 can comprise a thin portion 931, indicative of a traditional paddle face thickness. The weighted portion 930 can be further defined by areas of increased thickness over the thin portion 931. The thin portion 931 has a lower thickness than the weighted portion 930. FIG. 47 illustrates a cross-sectional view of a core 909 of the paddle head 901 showing a transition region between a thin portion 931 and a weighted portion 930.

The thin portion 931 of the face can comprise a thin portion thickness TN_T ranging between 0.01 inch and 0.09 inch. The thin portion thickness TN_T can be between 0.01 inch and 0.02 inch, 0.02 inch and 0.03 inch, 0.03 inch and 0.04 inch, 0.04 inch and 0.05 inch, 0.05 inch and 0.06 inch, 0.06 inch and 0.07 inch, 0.07 inch and 0.08 inch, or 0.08 inch and 0.09 inch.

The weighted portion 930 of the face can comprise a thick portion thickness TK_T. The thick portion thickness TK_T can vary depending on the number of thick regions on the face as well as their location(s). The thick portion thickness TK_T can range between 0.05 inch and 0.15 inch. The thick portion thickness can be 0.05 inch and 0.06 inch, 0.06 inch and 0.07 inch, 0.07 inch and 0.08 inch, 0.08 inch and 0.09 inch, 0.09 inch and 0.10 inch, 0.10 inch and 0.11 inch, 0.11 inch and 0.12 inch, 0.12 inch and 0.13 inch, 0.13 inch and 0.14 inch, or 0.14 inch and 0.15 inch.

In many embodiments, the face can comprise one or more weighted portions 930. The one or more weighted portions 930 can comprise a substantially symmetrical shape across the right and left lateral walls, as shown in FIGS. 47A-47D. The shape of the weighted portion 930 can be generally circular, ovular, quadrilateral, tear-dropped, quatrefoil, hexagonal, octagonal, diamond, pentagonal, trapezoidal, or any other suitable shape.

In an alternative embodiment, as shown in FIGS. 47E and 47F, the one or more weighted portion(s) 930 can comprise an asymmetrical shape. For example, the one or more weighted portion(s) 930 can partially extend into a lower-lateral edge or an upper-lateral edge. Many right-handed players have a tendency to impact the ball at a lower-right end of the face. Thickening the face at this region, and thereby increasing the mass at the site of impact, can reduce vibrational feedback and increase stability. Conversely, many left-handed players have a tendency to impact the ball at a lower-left end of the face. Accordingly, thickening the face at this region would reduce vibrational feedback and increase stability for a left-handed player.

In an alternative embodiment, the weighted attribute of the face can be derived from an insert or patch at least partially in contact with a rear surface of the face. In some embodiments, the paddle can further comprise one or more patches or weight pads in contact with a rear of the face. The one or more patches can comprise a material such as a metal, epoxy, polymer, or composite. In one specific embodiment, the one or more patches comprises a carbon fiber unidirectional laminate.

The one or more patches can be applied alone or in combination with a thickened portion of the face. In many embodiments, one or more patches are installed behind or directly in contact with one or more thickened regions of the face. The one or more patches behind a thickened region of the face can follow the curvature of the thickened region and at least partially extend onto the thin region as well. Using one or more patches in tandem with a thickened region of the face allows for fine-tuned weighting and targeted vibration control.

The one or more patches can comprise a plurality of patches layered in a fully or partially overlapping configuration. The number of the one or more patches can range inclusively between 1 and 10 patches. The number of the one or more patches can be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 patches. In some embodiments, the one or more patches will be in contact with a majority of the rear of the face. In alternative embodiments, the one or more patches will be used at smaller, specific sites along the face to control characteristic time (CT), CG, vibration, sound, or other play characteristics.

The one or more patches can be installed on the rear surface of the face using epoxy, welding, heat treatment, or any other suitable attachment means. In most embodiments, the one or more patches or weight pads will be mostly or fully in contact with the rear surface of the face. In some embodiments, the paddle comprises a first face plate, a second face plate, and an interior core between the first face plate and second face plate. In this particular embodiment, the one or more patches or recesses can be retained in a position behind the face due to the interior core pressing the patch(es) or insert(s) against the face.

In many embodiments of a paddle comprising a face with distinct weighted portions, the face can comprise a metallic or metal-adjacent material.

The one or more weighted portions can be placed at a face plate lower end to improve forgiveness. Moving CG closer towards the handle increases control during play, allowing the user to feel more in control, resulting in a more forgiving paddle.

Alternatively, the one or more weighted portions can be placed at a face plate top end to improve performance. Moving CG closer towards the upper end of the paddle increases power through impact, resulting in high performance benefits.

A pickleball paddle may comprise any one of the weight system embodiments discussed above or any combination thereof.

VII. EXAMPLES

A. Example I—Where is High/Low for Swing Weight and Balance Point

Example I provides a comparison between unweighted pickleball paddles and weighted pickleball paddles. More specifically, Example I illustrates comparative results related to distributing mass around the pickleball paddle and how that correlates to the balance point and swing weight of the pickleball paddle. The balance point equates to a distance from the butt end of the handle to a point on the paddle where the weight is evenly distributed, also referred to as the center of gravity, in the x-axis direction. For this example, a high balance point is anything over 9.50 inches, and a low balance point is anything under 9.50 inches. The swing weight refers to the horizontal MOI around a specific point 2.0 inches from the butt of the handle long the x-axis, essentially a measure of how much torque is needed in order to change the rotational speed of the paddle. For this example, a high swing weight is anything over 51.00 oz*in, and a low swing weight is anything under 51.00 oz*in. Additionally, in this example “12% CF fill frame” and “6% CF fill frame” are used to describe the material of the frame that was tested for this example. 12% CF fill frame refers to a composite material where nylon is the thermoplastic matrix and carbon fibers (specifically short fibers) are used as the reinforcement, making up 12% of the material. This is the same for 6% CF fill frame, except that is makes up 6% of the material. The frame itself is similar across all 8 paddles, with only the weighting configurations differing between models. All paddles started with the same mass before weight was added, in their respective tables.

The following weight configurations can be seen in FIGS. 30, 32, and 41. Described herein is an unweighted paddle with a 12% CF fill frame (hereafter known as Paddle 1). An unweighted paddle with a 6% CF fill frame (hereafter known as Paddle 1A). A paddle with a 12% CF fill frame comprising 7 g weight strips placed in the top left corner recess, top right corner recess, and top lateral wall recess (hereafter known as Paddle 2). A paddle with a 6% CF fill frame comprising 7 g weight strips placed in the top left corner recess, top right corner recess, and top lateral wall recess (hereafter known as Paddle 2A). A paddle with a 12% CF fill frame comprising 7 g weight strips placed in the top left corner recess and top right corner recess (hereafter known as Paddle 3). A paddle with a 6% CF fill frame comprising 7 g weight strips in the top left corner recess and top right corner recess (hereafter known as Paddle 3A). A paddle with a 12% CF fill frame comprising 7 g weight strips in the bottom left corner recess and bottom right corner recess (hereafter known as Paddle 4). A paddle with a 6% CF fill frame comprising 7 g weight strips in the bottom left corner recess and bottom right corner recess (hereafter known as Paddle 4A). A paddle with a 12% CF fill frame comprising an 8 g endcap weight at the butt of the handle (hereafter known as paddle 5). A paddle with a 6% CF fill frame comprising an 8 g endcap weight at the butt end of the handle (hereafter known as paddle 5A).

Paddles 6 and 6A are examples of standard weighted paddles configured to improve impact feel and increase forgiveness. Paddle 6 is a 12% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 1 g weight strip in the top right corner recess; a 1 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle; Paddle 6A is a 6% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 1 g weight strip in the top right corner recess; a 1 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle.

Furthermore, Paddles 7, 7A, 8, and 8A are examples of fitted paddles that were tailormade for a professional pickleball player (paddles 7 and 7A) and an amateur pickleball player (paddles 8 and 8A). Paddle 7 is a 12% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 3 g weight strip in the top right corner recess; a 3 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle. Paddle 7A is a 6% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 3 g weight strip in the top right corner recess; a 3 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle. Paddle 8 is a 12% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 1 g weight strip in the top right corner recess; a 1 g weight strip in the top left corner recess; a 4 g weight strip in the bottom right corner recess; a 4 g weight strip in the bottom left corner recess; and a 6 g endcap weight at the butt end of the handle. Paddle 8A is a 6% CF fill frame comprising a 1 g weight strip along the top lateral wall recess; a 1 g weight strip in the top right corner recess; a 1 g weight strip in the top left corner recess; a 4 g weight strip in the bottom right corner recess; a 4 g weight strip in the bottom left corner recess; and a 6 g endcap weight at the butt end of the handle.

Table 1 depicts a 12% CF fill frame with various weighting configurations. The frame itself is similar across all 7 paddles, with only the weighting configurations differing between models. As shown in Table 1, Paddle 2 and Paddle 3 have a high swing weight and a high balance point, which indicates that the paddle feels heavier to swing leading to a greater tactile response at impact, but with less control. Paddle 4 and Paddle 5 have low swing weights and low balance points, which indicates that the paddle feels lighter to swing leading to more control, but a less tactile response at impact. Paddle 7 is a weighting configuration chosen to create a balance between a tactile impact response and control, without making the paddle too heavy. Whereas, Paddle 8 is a weighting configuration chosen to focus more on control than a tactile response. Paddle 1, the unweighted paddle, has one of the lowest swing weights meaning that while it is easy to control, one won't get much tactile response from it.

Paddle 1A	181.7 g	0	g	9.25 in	46.57 oz*in

Paddle 6A	181.7 g	7	g	9.24 in	48.17 oz*in
Paddle 7A	181.7 g	11	g	9.37 in	50.00 oz*in
Paddle 8A	181.7 g	17	g	9.02 in	49.90 oz*in

Table 2 depicts a 6% CF fill frame with various weighting configurations. As shown in Table 2, Paddle 2 and Paddle 3 have a high swing weight and a high balance point, which indicates that the paddle feels heavier to swing leading to a greater tactile response at impact, but with less control. Paddle 4 and Paddle 5 have a low swing weight and a low balance point, which indicates that the paddle feels lighter to swing leading to more control, but a less tactile response at impact. Paddle 7 is a weighting configuration chosen to have a balance between a tactile impact response and control, without making the paddle too heavy. Whereas Paddle 8 is a weighting configuration chosen to focus more on control than a tactile response.

In comparison to Table 1, the overall trend in swing weight and balance point between individual paddles is the same as in Table 2. However, the swing weight values are less in Table 2 than in Table 1 and the balance point values are greater in Table 2 than in Table 1. The baseline mass of the paddles in Table 2 is less than the paddles in Table 1 meaning that the swing weight will be lower because there is less mass to be swung. Depending on whether a user wants a greater tactile response at impact or greater control, weight can be distributed around the paddle in order to achieve the desired performance characteristics. Placing weight at the top of the paddle leads to a greater tactile response but less control, whereas placing weight at the bottom of the paddle leads to greater control and a less tactile response.

B. Example II

A series of tests were conducted to demonstrate how the perimeter channels and endcap with adjustable weights significantly improve the ease of weight configuration adjustability within the pickleball paddle. Additionally, the tests exhibited an improvement in energy transfer during the collision of the pickle ball with the pickleball paddle.

An Unweighted Test Paddle having a 6% CF frame and no weights in the discrete recesses or butt end of the handle (Paddle 1A from Table 2) was given to a professional pickleball player (hereafter referred to as “Player A”). Player A was instructed to play with the Unweighted Test Paddle and determine any positive or negative characteristics regarding the performance and feel of the Unweighted Test Paddle. For 30 minutes, Player A was allowed to continue to explore playing with various adjustable weight configurations, as described above. Player A created noticeable differences in the stability, power, and the location of the sweet spot by adjusting the weights within the channels and endcap in order to achieve what he considered to be his desired performance. Further, the player noted the ease of adjustment when compared to the use of lead tape.

Player A was fit to his ideal weight configuration, which was implemented on a Weighted Test Paddle having a 6% CF frame; a 1 g weight strip along the top lateral wall recess; a 3 g weight strip in the top right corner recess; a 3 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle (Paddle 7A from Table 2). The Weighted Test Paddle and the Unweighted Test paddle were compared to display rebound coefficient improvements created by the weight system. The rebound coefficient can be defined as the ratio between the incident velocity and the exit velocity of the pickleball during impact with the pickleball paddle. The front face plate of each paddle was divided into 9 different sections by means of a grid. These 9 sections are as follows: top right (TR), top center (TC), top left (TL), middle right (MR), middle center (MC), middle left (ML), bottom right (BR), bottom center (BC), and bottom left (BL). The bottom center section is proximate to the top center of the handle. Each of the sections had approximately the same surface area and no portion of any section extended over any portion of the frame.

In order to determine the rebound coefficient, both the Weighted Test Paddle and the Unweighted Test Paddle were individually clamped at the handle such that the front face plate was perfectly horizontal. A pickleball was held at a height of approximately 69.4 inches above the approximate center of each section. The pickleball was dropped from the height and a rebound height was recorded by means of a high speed camera and Tracker software. The incident velocity and the exit velocity of each drop were derived from the recorded bounce height. This process was repeated two more times for each section.

Once the incident velocity and the exit velocity were determined, the rebound coefficient of each drop was calculated for both the Unweighted Test Paddle and the Weighted Test Paddle. Table 3 shows the rebound coefficient for the Unweighted Test Paddle and the Weighted Test Paddle. The weight system showed an increase in rebound coefficient in each of the 9 designated paddle sections.

As shown above in Table 3, the ideal weight configuration fit to Player A and implemented on the Weighted Test Paddle yielded a wide range of rebound coefficient percent improvements. The rebound coefficient percent improvements ranged from as little as a 2.55% improvement in the middle left section to a 48.35% improvement in the top right section. It is to be noted that even the smallest improvement in the rebound coefficient can yield noticeable improvements in performance and power. The rebound coefficient is similar to the coefficient of restitution such that it displays the elasticity of the collision between the pickleball and the pickleball paddle in each defined section. The improvement in the rebound coefficient signifies an improvement in the kinetic energy transfer during the collision, yielding improvements in performance and power output.

C. Example III

The example below discusses how a customized paddle weight arrangement improves paddle performance and feel characteristics for a professional level pickleball player. Player A of Examples I and II drew feel and performance comparisons between three different paddles: (1) an Unweighted Test Paddle; (2) a Standard Weighted Test Paddle; and (3) a Custom Weighted Test Paddle. The Unweighted Test Paddle comprises a 6% CF fill frame and no weights in the discrete recesses or butt end of the handle (Paddle 1A from Table 2). The Standard Weighted Test Paddle comprises a 6% CF fill frame and a standard paddle weighting arrangement including a 1 g weight strip along the top lateral wall recess; a 1 g weight strip in the top right corner recess; a 1 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle (Paddle 6A from Table 2). The Custom Weighted Test Paddle comprises a 6% CF fill frame and a weighting arrangement custom fit to Player A including a 1 g weight strip along the top lateral wall recess; a 3 g weight strip in the top right corner recess; a 3 g weight strip in the top left corner recess; a 1 g weight strip in the bottom right corner recess; a 1 g weight strip in the bottom left corner recess; and a 2 g endcap weight at the butt end of the handle (Paddle 7A from Table 2). Player A was asked to play with the Unweighted Test Paddle, the Standard Weighted Test Paddle, and the Custom Weighted Test Paddle to reach conclusions based on paddle performance and feel.

Player A found that he liked the lightweight paddle feel of the Unweighted Test Paddle, which allowed him to generate a high perceived hand speed and control the paddle for accurate shot placement. However, Player A wanted to generate greater speed and power in his return shots, specifically drives and smashes. Player A additionally found that he liked the lightweight paddle feel of the Standard Weighted Test Paddle but continued to struggle generating a desired speed and power in his return shots. Further, Player A observed a less solid impact feel in top left, top center, and top right paddle hits.

In order to maintain the lightweight paddle feel, high perceived hand speed, and shot placement control, the Custom Weighted Test Paddle maintained the Standard Weighted Test Paddle arrangement including a 1 g weight strip in the top lateral wall recess, a 1 g weight strip in the bottom left corner recess, a 1 g weight strip in the bottom right corner recess, and a 2 g endcap weight in the butt end of the handle. However, the Custom Weighted Test Paddle incorporated a 3 g weight strip in each of the top left and top right corner recesses (a 2 g weight increase from the Standard Weighted Test Paddle) to increase the balance point and swing weight values, as shown in Table 2, row 7. Increasing the balance point signifies the paddle center of gravity moving closer to the top lateral wall in the x-axis direction, which creates a softer feel for top left, top center, and top right paddle hits. Increasing the swing weight provides a greater tactile response at impact and greater momentum in the paddle during the swing to produce faster, more powerful return shots. As a result, the Weighted Test Paddle allowed Player A to maintain the high perceived hand speed and shot placement control of the Unweighted Test Paddle and the Standard Weighted Test Paddle, while generating a softer impact feel and faster return shots. These improvements gave Player A greater confidence to produce powerful, yet accurate return shots that would challenge his opponents in competition.

D. Example IV

The example below discusses how a customized paddle weight arrangement improves paddle performance and feel characteristics for an amateur level pickleball player. The amateur player of Example I (hereafter referred to as “Player B”) followed test procedures similar to those of Examples II and III to draw feel and performance comparisons between the Unweighted Test Paddle and Standard Weighted Test Paddle (as described in Example III), and a Custom Weighted Test Paddle. The Custom Weighted Test Paddle comprises a 6% CF fill frame and a weighting arrangement custom fit to Player B including a 1 g weight strip along the top lateral wall recess, a 1 g weight strip in the top right corner recess, a 1 g weight strip in the top left corner recess, a 4 g weight strip in the bottom right corner recess, a 4 g weight strip in the bottom left corner recess, and a 6 g endcap weight at the butt end of the handle (Paddle 8A from Table 2). Player B was asked to play with the Unweighted Test Paddle, the Standard Weighted Test Paddle, and the Custom Weighted Test Paddle to reach conclusions based on paddle performance and feel.

Player B found that he liked the lightweight paddle feel of the Unweighted Test Paddle, which allowed him to react quickly to higher-speed shots. However, Player B wanted to lower the trajectory in his long range return shots. Player B additionally found that he liked the lightweight paddle feel of the Standard Weighted Test Paddle but continued to struggle producing lower trajectory long range shots. Further, Player B observed a lack of shot placement control on off-center hits, specifically hits on the bottom left and bottom right of the paddle.

In order to maintain the lightweight paddle feel and quick reaction times, the Custom Weighted Test Paddle maintained the Standard Weighted Test Paddle arrangement including a 1 g weight strip in the top lateral wall recess, a 1 g weight strip in the top left corner recess, and a 1 g weight strip in the top right corner recess. However, the Custom Weighted Test Paddle incorporated a 4 g weight strip in each of the bottom left and top right corner recesses (a 3 g weight increase from the Standard Weighted Test Paddle) and a 6 g endcap weight (a 4 g weight increase form the Standard Weighted Test Paddle) to decrease the balance point value and and increase the swing weight value, as shown in Table 2, row 8. Decreasing the balance point signifies the paddle center of gravity moving closer to the bottom of the paddle in the x-axis direction, which creates more forgiveness and increased control in bottom left and bottom right paddle hits. Increasing the swing weight provides a greater tactile response at impact and greater momentum in the paddle during the swing to help control the ball with a downward trajectory and increase top spin to hit lower shots. As a result, the Weighted Test Paddle allowed Player B to maintain the quick reaction times he had with the Unweighted Test Paddle and the Standard Weighted Test Paddle, while improving the performance of off-center and long range shots. These improvements gave Player B the ability to hit more accurate shots that are difficult for his opponent to return in a game.
