FIELD OF THE INVENTION
The present invention relates generally to grips for use on various sporting equipment, and more particularly to grips for attachment to a piece of sporting equipment, such as by way of non-limiting example a lacrosse stick, which equipment includes a handle and for which use of the equipment benefits from particularized placement of a user's hand or hands on the handle of the equipment for learning, training or maximizing proficiency in use of the sporting equipment.
BACKGROUND
Athletes use a wide variety of sporting equipment, many of which items of sporting equipment include a racquet, stick, or other handled item having a head and a butt. Such equipment is manipulated during play, such as to hit or strike a ball or other item, catch or throw a ball or other item, pick up or carry a ball or other item, etc. Of course, when starting out in such a sport, a novice player often finds it challenging to properly and consistently perform such maneuvers, as properly carrying out such maneuvers typically requires consistent, proper placement of the user's hands on the handle of the sporting equipment in a way that maximizes their ability to carry out those various maneuvers.
By way of example, lacrosse is the oldest organized sport in North America. Lacrosse sticks typically include a shaft, a head, and a pocket. The lacrosse stick can be made from metal, wood, composite, plastic, or any other suitable material. The head of a lacrosse stick can be made from wood, metal, or any other suitable material, but is most typically formed of molded plastic. The pocket can be made from any suitable material such as cloth, string, mesh, leather rope, etc. The game is usually played with a rubber ball such as a hard rubber ball approximately the size of a tennis ball that is passed, scooped, caught, cradled and/or shot on goal. Players on a team can cradle a ball in their stick by moving their stick back and forth to create momentum for the ball inside of a stick's pocket to keep the ball in the user's pocket. Lacrosse is a highly skilled game which some have found hard to learn and grasp at any age, especially at an early age.
Lacrosse has been added as an Olympic game in 2023. However, one main obstacle has been the lack of worldwide participation, likewise precipitated by the difficulty for novices to learn the proper handling of the lacrosse stick in order to be able to properly carry out the various moves of the stick required during a game or practice. Of course, such challenges of properly manipulating an item of sporting equipment likewise apply to other items that require proper hand placement on the equipment to properly and effectively use that equipment during play.
Thus, there remains a need in the art of a training aid for teaching consistent, proper handling of a piece of sporting equipment, and particularly proper handling of a lacrosse stick, which can be used to aid a user in learning a set of fundamentals for the game, and which then may help the game expand to new people and grow in popularity as well as aid coaches in training beginner players in fundamentals, including for example how to hold a lacrosse stick or other handled sporting equipment.
SUMMARY OF THE INVENTION
Disclosed herein according to several exemplary embodiments is a training device for guiding a user in using a preferred grip, hand placement, palm placement, wrist orientation and/or finger orientation when holding a handle of a piece of sporting equipment, and in particularly preferred embodiments in holding, manipulating, and handling a lacrosse stick. The device comprises a grip configured for coupling to a shaft or handle of the sporting equipment and having a guide for guiding at least one digit, and more preferably at least two digits, on a user's hand to be oriented on the shaft or handle. There may be one, two, three, or more grips spaced apart from each other of like or differing configurations, wherein differing configurations may be provided dependent upon the intended location of the grip on the shaft or handle and the intended hand (i.e., left and/or right) of the user that is intended to be used with the grip.
In an exemplary embodiment, each of the grips has guides or grooves configured to guide placement of the user's fingers on the shaft or handle of the item of sporting equipment. The grooves may be formed as a concave recess in the grip, from one or more convex bulges on the grip, and/or other physical surface features creating a recess or bulge on the grip to form walls, ridges or a depression in the grip. The walls or ridges extend outward from the grip to form a channel in the grip. The guides may be configured for guiding the user's other digits, such as the user's index finger, middle finger, ring finger, and/or the pinky finger to be offset from the longitudinal axis and/or the latitudinal axis of the shaft or handle.
A guide or groove configured for positioning the user's thumb may be aligned on the shaft or handle approximately along the longitudinal axis of the shaft or handle or approximately offset by 10 degrees from the longitudinal axis of the shaft or handle, wherein the longitudinal axis extends along the long or lengthwise extension of the shaft or handle. For reference, the latitudinal axis is perpendicular to the longitudinal axis of the shaft or handle.
Further, different tolerances may be used when describing both the desired angle of orientation of the user's digits (e.g., thumb and fingers), or the corresponding grooves or guides on the grips which track with the desired angles of orientation. Thus, the grips may serve as finger guides with varying tolerances for guiding the angle of a user finger or digit on the shaft or handle of the sporting equipment.
For example, in at least one exemplary configuration, the guide or grip may have finger guides that only partially guide the user's fingers in a particular angle, with this guide or slot for the fingers or digits allowing for guiding the user's finger at an angle+/−(plus or minus) 40 degrees. Thus, and by way of example, if the angle of extension is 50 degrees offset from the longitudinal axis, then this partial angle means between 10 degrees to 90 degrees offset (50 degrees+/−40 degrees).
While the term “approximately” is used in this application, the term “approximately” when referring to any angle means that angle of orientation or guide+/−(plus or minus) 30 degrees. Thus, for example, if the angle of orientation or extension is described as offset approximately 30 degrees from the longitudinal axis of a shaft or handle, then this approximate angle means offset by anywhere from 0 degrees from the longitudinal axis or 60 degrees offset from the longitudinal axis of the shaft or handle. Further, the term “substantially” is used to describe any angle of orientation or extension or guide+/−(plus or minus) 20 degrees. For example, an angle of orientation or extension that is offset substantially 30 degrees from the longitudinal axis would be between 10 degrees offset and 50 degrees offset from the longitudinal axis. Further, the term “primarily” when referring to an angle of orientation or extension means that angle of orientation or extension+/−(plus or minus) 10 degrees from that angle of orientation or extension. Thus, for example, if the angle of orientation or extension is offset primarily 30 degrees from the longitudinal axis, then that means that an angle of orientation or extension is between 20 and 40 degrees offset from the longitudinal orientation or extension. Still further, the term “nearly” when referring to an angle of orientation or extension means+/−(plus or minus) 5 degrees from the preferred angle of orientation or extension. Thus, if an angle of orientation or extension is referred to as nearly 30 degrees offset from the longitudinal axis, that means that the angle is between 25 degrees and 35 degrees offset from the longitudinal axis of the shaft or handle. Still further, the term “nearly exactly” means+/−(plus or minus) three (3) degrees from the preferred angle of orientation or extension. Thus, if an angle of orientation or extension is referred to as nearly exactly 30 degrees offset from the longitudinal axis, that means that the angle is between 27 and 33 degrees offset from the longitudinal axis. Finally, the term “exactly” when referring to an angle of orientation or extension means that exact angle. Thus, if an angle of orientation or extension is referred to as exactly 30 degrees offset from the longitudinal axis, that means that the angle is 30 degrees offset from the longitudinal axis of the shaft or handle.
With respect to the positioning of a user's fingers on particular edges or bevels of the shaft or handle of the item of sporting equipment, the term largely refers to the positioning of that portion of the finger at least partially on that particular bevel, but also extending to one or more adjacent bevels or edges. Alternatively, if the term entirely is used with respect to the position of a user's fingers, then this means that the portion of a finger rests entirely on that particular bevel or edge.
In an exemplary configuration in which the item of sporting equipment particularly comprises a lacrosse stick, the entire lacrosse stick including the grips, the shaft, the head, and the pocket may serve as a training device. In another exemplary configuration, the grips may be incorporated or molded into the shaft to serve as a training device. The shaft can then be coupled to an existing head having a pocket. In still further exemplary configurations, the grips may be added to a shaft that has already been purchased. Any number of grips configured in accordance with aspects of the invention may be sold in a kit including one grip, two grips, three grips, or more. In a still further exemplary configuration, the grips may be incorporated or molded into a sleeve that may be slid onto the shaft. If the grips are incorporated into such a sleeve, then one or more grips (e.g., one, two or three grips) can be incorporated into the sleeve and then slid onto the shaft. In still yet another further exemplary configuration, the device may comprise a pre-molded shaft having the finger or grip guides molded therein.
Still other aspects, features and advantages of the invention are readily apparent from the following detailed description, simply by illustrating a number of particular embodiments and implementations, including the best mode contemplated for carrying out the invention. The invention is also capable of other and different embodiments, and its several details can be modified in various obvious respects, all without departing from the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The invention may be understood by referring to the following description and accompanying drawings. This description of an embodiment, set out below to enable one to practice an implementation of the invention, is not intended to limit the preferred embodiment, but to serve as a particular example thereof. Those skilled in the art should appreciate that they may readily use the conception and specific embodiments disclosed as a basis for modifying or designing other methods and systems for carrying out the same purposes of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, the use of the terms a, an, etc. does not denote a limitation of quantity, but rather denotes the presence of at least one of the referenced item.
The use of the terms “first”, “second”, and the like does not imply any particular order, but they are included to identify individual elements. Moreover, the use of the terms first, second, etc. does not denote any order of importance, but rather the terms first, second, etc. are used to distinguish one element from another. It will be further understood that the terms “comprises” and/or “comprising”, or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
Although some features may be described with respect to individual exemplary embodiments, aspects need not be limited thereto such that features from one or more exemplary embodiments may be combinable with other features from one or more exemplary embodiments.
For purposes of explaining various features of the invention, FIGS. 1 through 4C show various aspects of (i) a lacrosse stick of typical configuration, (ii) a user's hand (for referencing optimal positioning of portions of a user's hand with respect to the handle of a lacrosse stick), and (iii) various uses of a lacrosse stick by players during game play.
More particularly, FIG. 1 provides a side cross-sectional view of a traditional lacrosse stick shaft 10 having a plurality of different bevels. For example, a shaft body 11 has a first bevel 11.1, a second bevel 11.2, a third bevel 11.3, a fourth bevel 11.4, a fifth bevel 11.5, a sixth bevel 11.6, a seventh bevel 11.7 and an eighth bevel 11.8. Shaft body 11 also includes a plurality of corners or edges on the stick, including edges 11.9, 11.10, 11.11, 11.12, 11.13, 11.14, 11.15, and 11.16. Each of these edges or corners are between their respective bevels. For example, bevels 11.1 and 11.2 are divided by edge or corner 11.9. Edge or corner 11.10 sits between bevels 11.2 and 11.3, edge or corner 11.11 sits between bevels 11.3 and 11.4, edge or corner 11.12 sits between bevels 11.4 and 11.5, edge or corner 11.13 sits between bevels 11.5 and 11.6, edge or corner 11.14 sits between bevels 11.6 and 11.7, edge or corner 11.15 sits between bevels 11.17 and 11.18, and edge or corner 11.16 sits between bevels 11.8 and 11.1.
FIG. 2A is a front view of a lacrosse stick shaft 10 having a longitudinal axis 10i. There are three bevels shown, namely 11.1, 11.2 and 11.8. The inventor herein has discovered various hand digit (i.e., finger and thumb) orientations with respect to the handle of a lacrosse stick, such as the location of portions of various digits with respect to bevels and corners of the lacrosse stick and their angular orientation with respect to the longitudinal axis of the lacrosse stick, that provide a particularly optimal and desired placement for purposes of training a new player, or further developing an existing player, on how to hold and manipulate the lacrosse stick during game play. Specifically, such optimal and desired placement includes varied positions and angular orientations of the player's digits among each of their right and left hands, which are placed on the shaft of the lacrosse stick during training and play, one above the other, in positions dependent upon the current game play task being carried out by the player (e.g., cradling, throwing, catching, facing off, playing goalie etc.), and the handedness (right or left) of the player. Such optimal digit positioning ensures the development of a muscle memory that will assist in maintaining optimal form as the player progresses.
In this regard, FIG. 2A shows dotted lines for the approximate desired positioning for the two hands of a lacrosse player. For example, dotted line 21.1 represents the preferred orientation of or extension of a user's thumb and extends coaxially or parallel to the longitudinal axis 10i of the shaft 10 of the lacrosse stick, which longitudinal axis 10i is perpendicular to the latitudinal axis 30 of the shaft 10 of the lacrosse stick. Line 21.1 corresponds to the positioning of a user's thumb 21 (see also FIG. 3A).
As indicated above and as used throughout this specification, the term partially refers to an angle+/−(plus or minus) 40 degrees from that angle. The term approximately refers to an angle+/−(plus or minus) 30 degrees from that angle. The term substantially refers to an angle+/−(plus or minus) 20 degrees from that angle. The term primarily refers to an angle+/−(plus or minus) 10 degrees from that angle. The term nearly refers to an angle+/−(plus or minus) 5 degrees from that angle. The term nearly exactly refers to an angle+/−(plus or minus) 3 degrees from that angle. The term exactly refers to an angle that is exactly that angle.
In accordance with certain aspects of an embodiment, a preferred orientation of a right-handed thumb is 16 degrees off of the longitudinal axis 10i extending along bevel 11.3 of the shaft 10, such that the thumb extends largely from bevel 11.3 to bevel 11.2 and on edge 11.10 in extension. The angle of extension is based upon the origin of the axis of the angle which is the base knuckle 21d (FIG. 3A) of the thumb. For a left-handed player and as shown in FIG. 2B, the preferred angle of orientation is the opposite or 16 degrees off of longitudinal axis 10i taken along bevel 11.7, with the thumb largely extending from bevel 11.7 to 11.8 and on edge 11.15. With the left thumb, the angle of extension is calculated from the origin of the axis of this angle of extension or from the base knuckle 121d on thumb 121 (FIG. 3B).
While the angles and grips described below are based upon right-handed grips, those skilled in the art will recognize that complementary left-handed grips are also contemplated by and within the scope of the invention. Thus, the degrees of offset for the intended angles for the right-hand as shown in FIG. 2A are the same as the degrees of offset for the intended angles for the left-hand of FIG. 2B, such that the configurations of the right-handed grips discussed below may readily be adapted by those of ordinary skill in the art to configurations of left-handed grips.
In an exemplary configuration, the orientation of extension line 21.1 is partially 16 degrees off of the longitudinal axis 10i of shaft 10. Likewise, in certain configurations, this orientation or extension line is approximately 16 degrees off of the coaxial longitudinal axis 10i of the shaft 10. Further, in certain configurations, this orientation or extension line is substantially 16 degrees off of the coaxial longitudinal axis 10i of shaft 10. Further, in certain configurations, this orientation or extension line is primarily 16 degrees off of the longitudinal axis 10i of shaft 10. Still further, in certain configurations, this orientation or extension line 21.1 is nearly 16 degrees off of longitudinal axis 10i of the shaft. Still yet further, in certain configurations, this orientation or extension line 21.1 is nearly exactly 16 degrees off of the longitudinal axis of the shaft, and in yet other particularly preferred configurations, this orientation or extension line 21.1 is exactly 16 degrees off of the longitudinal axis of the shaft.
Dotted line 22.1 corresponds to the angle of positioning of a user's index finger 22 (see also FIG. 3A) and is calculated from the origin of the axis which is the middle knuckle 22d of the index finger. This angle may be offset by 20-25 degrees, and more preferably 20 degrees, down or off from the latitudinal axis 30 of the shaft. In various configurations this 20-degree offset from latitudinal axis 30 is partially offset 20 degrees, approximately offset 20 degrees, substantially offset 20 degrees, primarily offset 20 degrees, nearly offset 20 degrees, nearly exactly offset 20 degrees, or in a particularly preferred configuration exactly offset 20 degrees from the latitudinal axis 30.
Likewise, dotted line 23.1 corresponds to the angle of positioning of a user's middle finger 23 (see FIG. 3A) and is calculated from the origin of the axis which is located at the middle knuckle 23d of the middle finger 23. This angle may be offset by 20-25 degrees, and more preferably 23 degrees, down or off from the latitudinal axis 30 of the shaft. In various configurations, this 23-degree offset from latitudinal axis 30 is partially offset 23 degrees, approximately offset 23 degrees, substantially offset 23 degrees, primarily offset 23 degrees, nearly offset 23 degrees, nearly exactly offset 23 degrees, or in a particularly preferred configuration exactly offset 23 degrees from the latitudinal axis.
Further, dotted line 24.1 corresponds to the angle of positioning of a user's ring finger 24 (see FIG. 3A) and is calculated from the origin of the axis which is located at the middle knuckle 24d of the ring finger 24. This angle may be offset by 25-30 degrees, and more preferably 26 degrees, down from the latitudinal axis 30 of the shaft. In various configurations, this 26-degree offset from the latitudinal axis 30 is partially offset 26 degrees, approximately offset 26 degrees, substantially offset 26 degrees, primarily offset 26 degrees, nearly offset 26 degrees, nearly exactly offset 26 degrees, or in a particularly preferred configuration exactly offset 26 degrees from the latitudinal axis.
Still further, dotted line 25.1 corresponds to the angle of positioning of a user's pinky finger 25 (see FIG. 3A) and is calculated from the origin of the axis which is located at the middle knuckle 25d of the ring pinky finger 25. This angle may be offset by 23 degrees down from the latitudinal axis 30 of the shaft. In various configurations, this 23-degree offset from the latitudinal axis is partially offset 23 degrees, approximately offset 23 degrees, substantially offset 23 degrees, primarily offset 23 degrees, nearly offset 23 degrees, nearly exactly offset 23 degrees, or in a particularly preferred configuration exactly offset 23 degrees from the latitudinal axis.
FIG. 2A also shows another set of positions for a user's digits or fingers farther down the shaft 10 for use with another grip or guide (such as grip 70 or guides 71, 72, 73, 74, or 75 as shown in FIGS. 6A and 6B). This position shows the positioning of a user's thumb along axis 21.2, which is either partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly in line with longitudinal axis 10i or at a 16-degree offset from longitudinal axis 10i of shaft 30. Axis 22.2 corresponds to the positioning of the user's index finger at partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 20 degrees downward from latitudinal axis 30. Axis 23.2 corresponds to the positioning of the user's middle finger at partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly a 23-degree downward angle from axis 30. Axis 24.2 corresponds to the positioning of the user's ring finger at a partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 26-degree downward angle from axis 30. Axis 25.2 corresponds to the positioning of the user's pinky finger at a partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 23-degree downward angle from axis 30.
With continuing reference to FIG. 2A, another set of optimal positions is shown for a user's digits or fingers at a bottom portion or butt end of the shaft (such as grip 80 or guides 81, 82, 83, 84, or 85 as shown in FIGS. 6A and 6B). Here, axis 21.3 corresponds to the position of the user's thumb and extends partially, approximately, substantially, primarily, nearly, nearly exactly or exactly 5 degrees off of latitudinal axis 30 of shaft 10. Axis 22.3 corresponds to the position of the user's index finger and extends partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 5 degrees off of latitudinal axis 30 of shaft 10. Axis 23.3 corresponds to the position of the user's middle finger and extends partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 5 degrees off of latitudinal axis 30. Axis 24.3 corresponds to the position of the user's ring finger and extends partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 5 degrees off of latitudinal axis 30 of shaft 10. Likewise, axis 25.3 corresponds to the position of the user's pinky finger and extends approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 5 degrees off of latitudinal axis 30 of shaft 10. FIG. 2B likewise shows lacrosse stick shaft 10, here noting the optimal positions of a user's digits or fingers for a left-handed player. In this case, the noted angles form the bisecting lines of a left-handed grip guide. For example, there is shown a shaft 10 having a longitudinal axis 10i and a latitudinal axis 30. A series of dashed lines portray the desired angles of orientation of fingers of a left-hand on a shaft. These desired angles of orientation form the bisecting lines on the guides or grooves on a left-handed grip for a shaft, and in general are of like configuration to the angles described above with respect to FIG. 2A. Thus, axes 121.1, 122.1, 123.1, 124.1, and 125.1 equate to left-handed orientations, and thus mirror images (with respect to longitudinal axis 10i), of axes 21.1, 22.1, 23.1, 24.1, and 25.1, respectively, of FIG. 2A. More particularly, axis 121.1 shows the position of the user's thumb, which extends either partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 16 degrees off of longitudinal axis 10i. Axis 122.1 shows the positioning of the user's index finger, which extends partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 20 degrees downward from latitudinal axis 30 of shaft 10. Axis 123.1 shows the positioning of the user's middle finger and extends at partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly a 23-degree downward angle from latitudinal axis 30 of shaft 10. Axis 124.1 shows the positioning of the user's ring finger and extends at a partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 26-degree downward angle from latitudinal axis 30 of shaft 10. Axis 125.1 shows the positioning of the user's pinky finger and extends at a partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 23-degree downward angle from axis 30.
Likewise, and in similar fashion to the above, axes 121.2, 122.2, 123.2, 124.2, and 125.2 similarly equate to left-handed orientations of axes 21.2, 22.2, 23.2, 24.2, and 25.2, respectively, of FIG. 2A. Finally, axes 121.3, 122.3, 123.3, 124.3, and 125.3 equate to left-handed orientations of axes 21.3, 22.3, 23.3, 24.3, and 25.3, respectively, of FIG. 2A.
Next, and again for purposes of further detailing optimal placement of a user's digits or fingers on shaft 10 (see FIG. 5), FIG. 3A provides a front view of a palm of a hand. In this case, a right-hand is shown, although the following anatomical discussion is equally applicable to a user's left hand. This front view includes a thumb 21, having a first portion 21a and a second portion 21b as well as a base knuckle 21d, an index finger 22 having a first portion 22a, a second portion 22b, and a third portion 22c as well as a second knuckle 22d. There is a middle finger 23 having a first portion 23a, a second portion 23b, and a third portion 23c, as well as a second knuckle 23d. There is a ring finger 24 having a first portion 24a, a second portion 24b, and a third portion 24c and a second knuckle 24d. There is a pinky finger 25 having a first portion 25a, a second portion 25b and a third portion 25c as well as a second knuckle 25d. There is also a finger/palm crease 26 extending along the base of the four fingers between the palm 28 and the fingers, as well as another crease 27 extending along a center region of the palm 28 of the hand. Axis 26i extends substantially along crease 26. When a user holds a lacrosse stick, a bevel, such as bevel 5, or the edge or corner, such as edge or corner 11.12 or 11.13 of shaft 10, can rest inside of crease 26 of the user's hand and extend approximately, substantially, primarily, nearly, nearly exactly or exactly along axis 26i. In addition, there is also shown a base section 28.1 of palm 28 wherein this base section 28.1 includes the fatty part of the palm.
Likewise, FIG. 3B is a back view of a left-hand with thumb 121, and index finger 122, middle finger 123, ring finger 124, and pinky finger 125. Each of these fingers has an associated knuckle 121d, 122d, 123d, 124d, and 125d. Knuckle 121d is the base knuckle of the thumb, from which is the axis of the angle of orientation of the user's thumb 121. Knuckle 122d is the middle knuckle of the index finger 122 and forms the axis of the angle of orientation of the user's index finger 122. Knuckle 123d is the middle knuckle of the middle finger 123 and forms the axis of orientation of the user's middle finger 123. Knuckle 124d is the middle knuckle of the ring finger and forms the axis of orientation of the user's ring finger 124. Knuckle 125d is the middle knuckle of the pinky finger and forms the axis or orientation for the user's pinky finger 125. For further explanation (see FIG. 3A and FIG. 3B), the second knuckle on fingers 21, 121, 22, 122, 23, 123, 24, 124, 25, 125 separates the respective first portions such as portions 22a, 23a, 24a, 25a respectively from the second portions on those fingers such as 22b, 23b, 24b, and 25b.
Once the shaft is resting in the hand of the player, the fingers wrap around the shaft such that the different sections or portions of the user's fingers then extend to contact the different bevels on the lacrosse stick. With these fingers wrapping around the stick, they then extend along an axis around the lacrosse stick across the different bevels.
The term “largely” as used herein to refer to the extent of contact of the user's hand or digits with the shaft 10 means that a portion of the digit or finger contacts either entirely on a particular bevel or at least partially on the particular bevel and then on one or more adjacent bevels and/or one or more adjacent edges. Alternatively, the term “entirely” used in this context with respect to placement of a portion of a user's digit or finger means placement entirely on a single bevel or on two particular bevels or on a single edge or on two particular edges.
For example, when maintaining an optimal right-handed positioning of a user's right hand on shaft 10, index finger portion 22a would largely sit on bevel 11.5, portion 22b would sit largely on bevel 11.7 and portion 22c would sit largely on bevel 11.8. Index finger 22 would extend along an index finger axis 22i which would extend coaxially with axis 22.1 or axis 22.2, which then is guided by guide or groove 62 or 72 of grips 60 or 70 (FIG. 6A) that are discussed in greater detail below. An opposite thumb 21 would sit largely along bevel 11.3 as well as crossing over to bevel 11.2 and extend along an axis 21i, coaxially with axis 21.1 or 21.2 (see FIG. 6B) and guided by guides 61 or 71 of grips 60 or 70, respectively (FIG. 6A). For example, in at least one embodiment, thumb portion 21a would sit largely along bevel 11.3 while thumb portion 21b would sit largely along bevel 11.2.
Likewise, when maintaining an optimal left-handed positioning of a user's left hand on shaft 10, index finger portion 22a would largely sit on bevel 11.4, portion 22b would sit largely on bevel 11.7, and portion 22c would sit largely on bevel 11.6. Index finger 22 would extend along an index finger axis 22i which would extend coaxially with axis 22.3, which then is guided by guide or groove 82 of grip 80 (FIG. 6A) discussed in greater detail below. Thumb portion 21a of an opposite thumb 21 would sit largely along bevel 11.3 and cross over to bevel 11.2, and thumb portion 21.b would sit largely along bevel 11.5 and extend along an axis 21.3 coaxially with axis 21.3 guided by guide 81 of grip 80 (FIG. 6A).
With respect to the optimal position of the user's middle finger 23, it may extend along axis 23i, such that first portion 23a largely contacts bevel 11.6, second portion 23b largely contacts bevel 11.7, and third portion 23c largely extends across bevel 11.8. The orientation or extension of the user's middle finger 23 extends along axis 23i, coaxially with axis 23.1, or 23.2, or 23.3 which is a bisecting axis for any one of guides or grooves 63, 73, or 83 on any one of grips 60, 70, or 80.
With respect to the optimal position of the user's ring finger 24, it may extend along axis 24i, such that first portion 24a largely sits along bevel 11.7, second portion 24b largely sits along bevel 11.8, and third portion 24c largely sits along bevels 11.1. The orientation or extension of the user's ring finger 24 extends along axis 24i, coaxially with axis 24.1, 24.2 or 24.3 which extends coaxially with any one of guides or grooves 64, 74, or 84 on any one of grips 60, 70, or 80.
With respect to the optimal position of the user's pinky finger 25, it may extend along axis 25i, such that first portion 25a sits largely along bevel 11.7, second portion 25b sits largely across bevel 11.8, and third portion 25c sits largely along bevels 11.1. The orientation or extension of the user's pinky finger 25 extends along axis 25i substantially coaxially with any one of axis 25.1, 25.2 or 25.3 which bisect guides or grooves 65, 75, or 85 on any one of grips 60, 70 or 80.
Those skilled in the art will readily recognize that while the foregoing explanation of ideal positioning of a user's hands are presented here with respect to placement of the user's right hand on either of top grip 60 or middle grip 70 and the user's left hand on bottom grip 80, grips may likewise be provided in a configuration for a left-handed player (in which the user's left hand is placed on either of top grip 60 or middle grip 70 and the user's right hand on bottom grip 80) by simply mirroring the hand digit placements discussed above, all without departing from the scope of the invention.
Further, it is desirable that the user's wrist be properly oriented with respect to shaft 10 to ensure optimal control over the shaft during use. In this regard, the ideal wrist position is one in which the palm is facing outwards, away from the body in the same manner in which the head of the lacrosse stick faces outwards when catching and passing a ball or when using a tennis racquet to hit a forehand. When fingers are placed in the finger grooves and the thumb and index finger are placed in their respective grooves, the wrist will be in an optimal position allowing the hand to be at generally a 90-degree angle to the longitudinal axis 10.
For purposes of further illustration, FIG. 4A is a view of two players having a catch using lacrosse sticks shown by reference numeral 40. FIG. 4B is two players running to scoop a ground ball shown by reference numeral 41. FIG. 4C is a view of three players running and cradling shown by reference numeral 42. Each of these activities that are carried out in game play requires that the player position their hand, and more particularly the digits/fingers on their hand, in the foregoing manner in order to optimally carry out those varied activities. Thus, grips 60, 70, and 80 as discussed in detail below are particularly configured to assist the players in holding the shaft 10 while performing multiple different movements, including but not limited to the foregoing catching, throwing, cradling, or scooping of a ball.
Moreover, while the foregoing discussion references optimal digit placement on the shaft of a lacrosse stick that were discovered by applicant to have success in repetitively training a user to optimally perform those activities that a player must perform during play, those skilled in the art will recognize that varied other digit orientations may be specifically applied to other sporting equipment having handles that must be grasped and manipulated in specific ways in order to optimally carry out the maneuvers required during their own game play, such that the configurations of grips 60, 70, and 80 may be adapted to incorporate those alternative applications.
Next and in accordance with certain aspects of an embodiment of the invention, FIG. 5 is a front view of a lacrosse stick having training grips 60, 70, and 80 positioned thereon configured in accordance with at least certain aspects of the invention. FIG. 5 particularly shows angles for orientation or extension of a user's digits or fingers. In this case, a right-hand placement of grips is shown; however, a left-hand placement of grips can also be used. With this view, there is shown a full lacrosse stick 50 having a head 51 and a shaft 10. Disposed on shaft 10 is a grip 60 having finger placements, guides or grooves 62, 63, 64, and 65 having corresponding angles formed by bisecting axes 22.1, 23.1, 24.1, and 25.1 (configured as discussed above) wherein these axes bisects their corresponding guides and intersect longitudinal axis 10i to form angles 66, 67, 68, and 69. Thus, finger placement, guide or groove 62 is configured for positioning a user's index finger and has a bisecting axis 22.1 with a downward sloping angle 66 of partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 20 degrees off of latitudinal axis 30 of shaft 10. Finger placement guide or groove 63 is configured for positioning a user's middle finger and has a bisecting axis 23.1 with a downward sloping angle 67 of partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 23 degrees off from latitudinal axis 30 of shaft 10. Finger placement or guide or groove 64 is configured for positioning a user's ring finger and has a bisecting axis 24.1 with a downward sloping angle of partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 26 degrees which slopes off or down from latitudinal axis 30 of shaft 10. Finger placement, guide or groove 65 is configured for positioning the user's pinky finger and has a downward sloping angle 69 of partially, approximately, substantially, primarily, nearly, nearly exactly or in a particularly preferred configuration exactly 23 degrees off from latitudinal axis 30 of shaft 10.
There are also shown grips 70 and 80, and stopper or butt end 90. Grip 70 is preferably of like configuration to grip 60, while grip 80 as shown in the exemplary configuration of FIG. 5 is configured for receiving a user's left hand, and thus includes finger placements, guides or grooves having angles corresponding to bisecting angles 21.3, 22.3, 23.3, 24.3, and 25.3 (see FIG. 2A) as discussed above.
FIGS. 6A and 6B show opposing side views of the training grips 60, 70, and 80 as applied to lacrosse stick 50. Again, as reflected in these FIGS. 6A and 6B, a right-hand placement of grips is shown, however, a left-hand placement of grips can also be used. For example, lacrosse stick 50 includes shaft 10 with grip 60 having a thumb groove or guide 61 on the grip 60, an index finger groove or guide 62 on the grip 60, a middle finger guide or groove 63, a ring finger guide or groove 64 and a pinky finger groove or guide 65. Once again, axis 22.1 bisects groove or guide 62, axis 23.1 bisects groove or guide 63, axis 24.1 bisects guide or groove 64, and axis 25.1 bisects groove or guide 65. Similarly, grip 70 includes a thumb groove or guide 71, an index finger groove or guide 72, the middle finger guide or groove 73, a ring finger guide or groove 74 and pinky finger guide or groove 75. Axis 22.2 bisects groove or guide 72, axis 23.2 bisects groove 73, axis 24.2 bisects groove 74, and axis 25.2 bisects groove or guide 75.
In addition, with grip 80 there is shown groove or guide 81 for a thumb, groove or guide 82 which is for the index finger, groove or guide 83 which is for the middle finger, groove or guide 84 which is for the ring finger, and groove or guide 85 which is for the pinky finger. Axis 22.3 bisects groove or guide 82, axis 23.3 bisects groove or guide 83, axis 24.3 bisects groove or guide 84, and axis 25.3 bisects groove or guide 85. Thus, each of these axes are configured to define the angle of orientation or extension of the grooves.
In particular, FIG. 6B is an opposite side view of the training grips 60, 70, and 80 on lacrosse stick 50 from that shown in FIG. 6A. In this view, there is shown stick 50 with shaft 10 having longitudinal axis 10i. Grip 60 has a thumb guide or groove 61 with bisecting axis 21.1. Grip 70 has a thumb guide or groove 71 with bisecting axis 21.2. Grip 80 has a thumb guide or groove 81 with bisecting axis 21.3. Longitudinal axis 21.1 intersects longitudinal axis 10i at an angle 21.1a of partially, approximately, substantially, primarily, nearly, nearly exactly or exactly 10°. Axis 21.2 intersects longitudinal axis 10i at an angle 21.2a of partially, approximately, substantially, primarily, nearly, nearly exactly or exactly 10°. Axis 21.3 intersects longitudinal axis 10i at an angle of partially, approximately, substantially, primarily, nearly, nearly exactly or exactly 85°.
As described above, shaft 10 has different bevels, such as bevels 11.6, 11.7, and 11.8. Moreover, the interior of each of the training grips preferably exhibit a complementary contour to the bevels of shaft 10 to ensure proper overall alignment of the user's hand with respect to lacrosse stick 50, including proper orientation with respect to the head of the stick.
FIG. 7 is a side view of a lacrosse stick shaft 10 including grips 60, 70, and 80. Once again, a right-hand placement of grips is shown; however, a left-hand placement of grips can also be used. As shown, thumb guide or groove 61 is shown bisecting axis 21.1. Grip 70 has thumb guide or groove 71 bisecting axis 21.2. Grip 80 has thumb guide or groove 81 bisecting axis 21.3.
FIG. 8 is a side view of a kit comprising multiple training grips 60, 70, 80 configured as discussed above and free of a lacrosse stick. In this case, right-hand grips are shown, however, left-hand grips can also be used. This view shows the three grips 60, 70 and 80 which can be attached as an after-market piece on an existing shaft or an existing stick that may or may not have bevels. These three grips 60, 70, and 80 can be sold in a kit or separately.
Likewise, FIG. 9 is a side view of a kit comprising two training grips-namely, a single one of top or middle grips 60 and 70, and a bottom grip 80. In this case, right-hand grips are shown; however, left-hand grips can also be used.
Likewise, FIG. 10 is a side view of a single training grip (e.g., one of upper or middle training grips 60 or 70) which may be provided as a single item. In this case, a right-hand grip is shown; however, a left-hand grip can also be used.
Thus, as disclosed above the training grips 60, 70, and 80 may be sold as part of a full lacrosse stick, as part of a shaft, or as separate grips in a kit of one grip, two grips or three grips in a kit. The training grips may be applied by sliding each of training grips 60, 70, and 80 over the butt end of the shaft 10 if the butt is removed and put back on once the grip is applied, or over the head end if the head is removed, with the interior of each of grips 60, 70, and 80 having a shape (such as by way of non-limiting example an octagonal shaft) conforming to the exterior shape of the shaft 10 to ensure a tight grip while allowing installation and removal. In another exemplary configuration, one or more of training grips 60, 70, and 80 may be provided as multiple pieces, such as two pieces, that may be joined together about the shaft 10 and snapped, taped, or otherwise joined together to hold the multiple pieces of the training grip together on shaft 10. The grips may still further be embedded or molded into the shaft 50 or as part of a sleeve slipped over the shaft.
Next and in accordance with still further aspects of an embodiment, FIGS. 11A through 12D show various views of training grips 160, 170, and 180, wherein training grips 160 and 170 are configured as right-handed grips configured for positioning on shaft 10 adjacent head 51 and at a generally mid position along the length of shaft 10, respectively, and training grip 180 is configured as a left-handed grip configured for positioning on shaft 10 adjacent the butt end of shaft 10. Those skilled in the art will recognize that grips 160 and 170 may likewise be provided in left-handed configurations as mirror images of those shown in FIGS. 11A through 12D, and that grip 180 may likewise be provided in a right-handed configuration as a mirror image of that shown in FIGS. 11A through 12D, without departing from the spirit and scope of the invention.
With particular reference to the side view of FIG. 11A, each of grips 160, 170, and 180 has at least one digit placement in the form of an indent, depression or ridge defining a slot or groove for receiving the tip of a user's thumb or index finger. For example, grip 160 has a thumb groove 161, grip 170 has a thumb groove 171, and grip 180 has an index finger groove 181. Thumb grooves 161 and 171 are configured to orient a user's thumb (and in the exemplary configuration of FIGS. 11A-12E specifically a user's right thumb) partially, approximately, substantially, primarily, nearly, nearly exactly or exactly coaxial to the longitudinal axis 10i to stick 10. Groove 181 is configured to orient a user's index finger (and in the exemplary configuration of FIGS. 11A-12D specifically a user's left index finger) in a partially, approximately, substantially, primarily, nearly, nearly exactly or exactly horizontal manner or in a manner transverse to the longitudinal axis 10i of stick 10.
FIG. 11B is a perspective view of the lacrosse stick of FIG. 11A with grips 160, 170, and 180, again showing thumb groove 161 on grip 160, thumb groove 171 on grip 170, and index finger groove 181 on grip 180.
FIG. 12A is a bottom perspective view of training grips 160, 170, and 180 apart from the lacrosse stick of FIGS. 11A and 11B, FIG. 12B is a perspective view of training grips 160, 170, and 180, FIG. 12C is a side view of training grips 160, 170, and 180, and FIG. 12D is an additional side view of training grips 160, 170, and 180 (grips 160 and 170 shown from the perspective of the left side of their respective views in FIG. 12C, and grip 180 shown from the perspective of the right side of the view in FIG. 12C) showing further detail of the grooves and ridges on each respective training grip 160, 170, and 180. With reference to FIGS. 12A-12D, grip 160 includes a body section 162, thumb groove 161, and finger grooves 163, 165 separated and defined by ridges 164, 166, and 168. There is also a protrusion 167 along the lower portion of grip 160 generally on the side of grip 160 opposite grooves 163 and 165, which protrusion 167 is configured and positioned on grip 160 to space the user's palm away from the rest of the shaft 10 when the digits of the user's hand are placed in their respective grooves. There is an inside portion or region 169 of grip 160 which has, by way of non-limiting example, an octagonal shape of approximately 8 flat sides, which are complementary to the exterior of shaft 10 and thus fit around the exterior of shaft 10. While the inner shape is shown as octagonal, any suitable shape can be used that will conform to the exterior of the shaft 10 while enabling sliding installation along with a tight fit. The exterior shape of grip 160 is substantially or at least partially cylindrical, such as that of a cylinder with additional grooves or indents or protrusions. Likewise, grip 170 similarly includes a body section 172, thumb groove 171, and finger grooves 173, 175 separated and defined by ridges or protrusions 174, 176, and 178. As in the configuration of grip 160, protrusion section 177 is provided along the lower portion of grip 170 generally on the side of grip 170 opposite grooves 173 and 175, which protrusion section 177 once again spaces the user's palm away from the shaft of the stick. In an exemplary configuration, grips 160 and 170 are of the same or substantially the same configuration. Training grip 170 also includes an interior region 179 which, again as with training grip 160, may have eight interior sides in an octagonal manner which is used to slide over shaft 10. Further, bottom grip 180 has a body section 182, index finger groove 181, and finger grooves 183 and 185 separated and defined by alternating ridges 184, 186, and 188. Likewise, grip 180 includes a protrusion section 187 along the lower portion of grip 180 generally on the side of grip 180 opposite grooves 183 and 185, which protrusion section 187 again spaces the user's palm away from the shaft of the stick. While there are only approximately two or three finger grooves shown in grips 160, 170, and 180, in differing configurations the grips described herein in each embodiment can have any suitable number of finger grooves or ridges, or even no finger grooves, thumb grooves, or ridges at all (in the case of a configuration providing only a palm spacer feature as discussed below), and thus may have groove and ridge configurations other than those shown in the Figures without departing from the scope of the invention.
As noted above, each of training grips 160, 170 and 180 include protrusions 167, 177, and 187, respectively, in each case to form a palm spacer that is configured to space the bottom half or fatty part (the thenar) of the user's palm 28.1 (See FIG. 3A) away from the rest of the shaft 10, enabling the wrist to be generally at a 90 degree angle to the longitudinal axis. On training grips 160 and 170, this promotes having at least one of the edges or corners such as edge or corner 11.11, 11.12, 11.13 or 11.14 (See FIG. 1) resting approximately along axis 26i, which is essentially the axis of a crease dividing the user's fingers from the palm 28 of the user's hand (See again FIG. 3A). The position of the user's hands is then configured to give the user much more control over the stick and/or shaft 10.
Next and in accordance with still further aspects of an embodiment, FIG. 13A-13L show different views of grip 170 particularly configured for ambidextrous use by either hand of the user (training grip 160 preferably having the same construction as training grip 170, such that only training grip 170 is shown for simplicity of the following discussion). As indicated above, grip 170 has thumb grooves 171 (a) and 171 (b) in FIG. 13E on opposite sides of training grip 170, in addition to finger grooves 173 and 175 separated and defined by ridges 174, 176 and 178. These grooves and ridges are on body 172. Grip 170 includes protrusion sections 177 (best viewed in FIG. 13L) to space a user's palm away from stick 10. Thus, with this configuration, the user can hold onto the stick using grips 160 and 170 with either their left hand or their right hand as their top hand and have his appropriate hand orientated in approximately the correct orientation. The top and bottom views of FIGS. 13D and 13F also show the interior regions 179 forming a substantially octagonal shape to fit around an associated shaft 10. As shown in FIG. 13E, a weight 190 may optionally be provided that can be inserted into any of the foregoing training grips or added to an exterior region of the grip in the form of an add on element 191. The extra weight may be used to help a user develop the muscles of their hand, wrist and forearm as they use the stick. In addition, weights can be placed over the training grips, such as grips 160 and 170, or inserted into or placed over other grips according to the various embodiments described herein.
FIGS. 14A-14L likewise show different views of bottom grip 180. In an exemplary configuration, bottom grip 180 has a body section 182, index finger grooves 181a and 181b in FIG. 14E, and finger grooves 183 and 185 separated and defined by ridges 184, 186 and 188. Additionally, bottom grip 180 includes protrusion section 187 on opposite sides of grip 180 and generally beneath each index finger groove 181a and 181b again to space a user's palm away from stick 10 when the digits of the user's hand are placed in their respective grooves. There is also interior section 189 shown which is, by way of non-limiting example, an octagonal shape configured to fit around and conform to the exterior of shaft 10. Because finger grooves 181a and 181b are positioned on opposite sides of bottom grip 180, the user may hold the stick in either hand while having their fingers in at least finger grooves 183 and 185. While in the exemplary configuration of FIGS. 14A-14L′ there are two finger grooves shown, additional finger grooves may likewise be added to the grip.
As shown in the above description of training grips 160, 170, and 180 configured for ambidextrous use by either hand of a player, the ridges that define digit-receiving grooves on each such training grip extend along a downward curved arc (best viewed in FIGS. 13J and 14J) between digit slots 171a and 171b and between digit slots 181a and 181b. This configuration provides for proper digit placement regardless of which user top hand is used to grasp the training grip.
Thus, this configuration of training grips 160, 170, and 180 can be used with more tolerance for players wanting a different feel. For example, these grips can be used for more advanced players who still want guidance on their finger placement while having the freedom to switch hands and grip the stick in either hand while still using a single set of grips.
Next, FIG. 15A shows a back view of a lacrosse stick having palm spacing grips 200, 210 and 220 according to further aspects of an embodiment. Grips 200, 210 are configured in a similar manner to the ambidextrous grip configurations described above with reference to FIGS. 13A through 13L for grips 160 and 170, with the exception that grips 200 and 210 are here provided without grooves for a user's finger digits. More particularly, while grips 200 and 210 each have thumb grooves 201a and 201b and 211a and 211b, respectively, they do not have additional finger grooves as in the above embodiments.
Thumb grooves 201a and 201b on grip 200 are again positioned on opposite sides of a body section 202 of grip 200. Further and as described above with reference to the embodiment shown in FIGS. 13A through 14L, grip 200 includes protruding back endsections 203 forming a palm spacer as described above to push or space a user's palm away from shaft 10 of the stick. Spaced down the shaft from grip 200 is grip 210, which is substantially or entirely identical in size and shape to grip 200. Grip 210 has thumb grooves 211a and 211b positioned on opposite sides of a body section 212 of grip 210. Further and as described above with reference to the embodiment shown in FIGS. 13A through 14L, grip 210 includes protruding back end sections 213 forming a palm spacer as described above to push or space a user's palm away from shaft 10 of the stick.
Spaced farther along the stick and at the distal end opposite of the head 51 is bottom grip 220. Bottom grip 220 has side index finger grooves 221a and 221b positioned on opposite sides of a body section 222 of grip 220. Further and as described above with reference to the embodiment shown in FIGS. 14A through 14L, grip 220 includes protruding back end sections 223 forming a palm spacer as described above to push or space a user's palm away from shaft 10 of the stick.
FIG. 15B is a side view of the lacrosse stick of FIG. 15A showing grips 200, 210, and 220 spaced apart from each other along shaft 10. As discussed above, grip 200 includes thumb grooves 201a and 201b configured to orient a user's thumb partially, approximately, substantially, primarily, nearly, nearly exactly or exactly coaxial to the longitudinal axis 10i to stick 10. In addition, protruding back end sections 203 protrude out from body 202 and are configured to space the user's palm away from the shaft when the user grips the stick.
Similarly, grip 210 includes thumb grooves 211a and 211b configured to orient a user's thumb partially, approximately, substantially, primarily, nearly, nearly exactly or exactly coaxial to the longitudinal axis 10i to stick 10. In addition, protruding back end sections 213 protrude out from body 212 and are configured to space the user's palm away from the shaft when the user grips the stick.
In particular and as described above with respect to the embodiment shown in FIGS. 13A through 13L, these protruding back end sections 203 and 213 are configured as palm spacers which are configured to space the bottom portion or fatty part (the thenar) of a user's palm 28.1 (See FIG. 3A) away from shaft 10. This then promotes having one of the edges or corners, such as edge or corner 11.11, 11.12, 11.13 or 11.14 (See FIG. 1), resting approximately along axis 26i, which is essentially the axis of a crease dividing the fingers from the palm 28 of a user's hand (see again FIG. 3A). The position of the user's hand is then configured to give the user much more control over the stick and/or shaft 10.
Likewise, once again spaced farther along the stick and at the distal end opposite of the head 51 in FIG. 15A is bottom grip 220 having side index finger grooves 221a and 221b positioned on opposite sides of a body section 222 of grip 220. Further and as described above with reference to the embodiment shown in FIGS. 14A through 14L, grip 220 includes protruding back end sections 223 forming a palm spacer to push or space a user's palm away from shaft 10 of the stick as described above.
FIG. 16A shows the three grips 200, 210 and 220 spaced apart from each other without the stick or shaft shown. Grip 200 is shown in side view with thumb groove 201b, body section 202 and one of protruding back end sections 203 configured to space the user's palm away from the stick when the user is holding the stick. Grip 210 also shows thumb groove 211b on body 212 with one of back end spacer sections 213 configured to space a user's palm away from the shaft of the stick when the user is holding the stick. Finally, grip 220 shows side index finger groove 221b positioned on body section 222 of grip 220 and one of protruding back end sections 223 forming a palm spacer to push or space a user's palm away from shaft 10 of the stick as described above.
FIG. 16B likewise shows a front view of the grips of FIG. 16A with grip 200 having opposite spaced thumb grooves 201a and 201b as well as body section 202 and protruding sections 203 shown. Grip 210 likewise has opposite spaced thumb grooves 211a and 211b as well as body section 212 and protruding sections 213 shown. Bottom grip 220 likewise shows body section 222 with opposite index finger grooves 221a and 221b and protruding sections 223 shown.
FIGS. 17A-17I further show various additional views of grips 200 and 210 (with only grip 200 being labeled here for simplicity given the like construction of grips 200 and 210). As shown in those figures, grip 200 has opposite spaced thumb grooves 201a and 201b, body section 202 and protruding back end sections 203, which protrude out from body section 202 to space the user's palm away from the shaft when the user has placed their thumb to rest on or inside of the thumb groove 201a or 201b. For example, in FIG. 17B there is shown the outline of a thumb 230 in dashed dotted lines extending along the grip 200 and being placed on or in groove 201b. In addition, arrow 231 shows the direction in which the user's palm is pushed out and away from the shaft of the stick, thereby orienting the user's hand in the correct alignment along the shaft.
Likewise, FIGS. 18A and 18B show various additional view of grip 220 including index finger grooves 221a and 221b, body section 222 and protruding sections 223, which protrude out from body section 222 to space the user's palm away from the shaft when the user has placed their index finger to rest on or inside of the index finger groove 221a.
In addition, as shown in FIGS. 17A, 17C, 17E, 17G, and 17I of grip 200, and in FIG. 18B of grip 220, an octagonal shaped interior region 207 and 227, respectively, is provided, which is configured to grip around a lacrosse shaft which is also octagonally shaped. While this octagonal shaped interior region 207 is shown, any suitable shape can be used to grip the shaft.
Furthermore, and with particular reference to FIG. 17F, optional weighted insert 240 can be embedded into the grip 200, or optional coupled weighted section 241 can be coupled to the grip 200 to provide additional weight in or on the grip. The weighted section can be made from any suitable material such as lead, tungsten or any other material which provides additional weight to the stick. The additional weight then allows for greater development of a user's muscles when they are playing with the stick. These types of weights or any composition of the weights mentioned above can be used with any of the grips described above including 60, 70, 80 in FIG. 5 or any other weight affixed, added, etc. to shaft 10.
Those skilled in the art will recognize that training devices may be provided in configurations that vary from the specific configurations shown above without departing from the scope of the invention. For example, while thumb grooves or guides are shown in various embodiments as positioning the user's thumb in a largely vertical orientation with respect to the longitudinal axis of a shaft or handle of an item of sporting equipment, such thumb grooves or guides may likewise be configured to position the user's thumb in a largely horizontal orientation (such as, by way of non-limiting example, −5 to +5 degrees offset from the latitudinal axis of the shaft or handle) to accommodate varied training techniques-such as, in the sport of lacrosse, teaching a player to properly orient their hand for cradling a lacrosse stick, in which case their hand will be positioned at the top of the shaft with their thumb in a largely horizontal position. Thus, training devices as discussed herein and in accordance with at least certain aspects of the invention may be provided with similar variations to accommodate varied training needs.
Having now fully set forth the preferred embodiments and certain modifications of the concept underlying the present invention, various other embodiments as well as certain variations and modifications of the embodiments herein shown and described will obviously occur to those skilled in the art upon becoming familiar with said underlying concept. Thus, it should be understood, therefore, that the invention may be practiced otherwise than as specifically set forth herein.
