The present invention relates generally to lacrosse equipment, and more particularly, to a lacrosse head pocket and a related method of manufacture.
Conventional lacrosse sticks include a head joined with a handle. The head includes a frame that forms a region within which a lacrosse ball can be caught, held or shot. A net is joined with the back side of the frame. Typically, the net is constructed from laces or mesh, which is further connected to the frame via multiple small holes defined by the frame. The net forms a pocket within which the lacrosse ball is held while a player is in possession of the ball, and can be a determinant factor as to the player's ability to catch, retain and shoot the ball.
Different lacrosse players at different positions typically prefer pockets having certain profiles and handling characteristics. For example, while a player at an attack position generally prefers a pocket configured for vertical cradling and accurate shooting of a lacrosse ball, a midfielder prefers a pocket for better control and safely carrying a ball by cradling it back and forth, causing the ball to snugly set in the pocket due to centripetal forces. A defensive player generally prefers a pocket configured for better cradling and release with a defensive stick. Further, depending on the player, they may prefer a modification of the pocket. For example, an attacker may prefer their shooting strings, which generally form the ramp of the pocket from which the lacrosse ball is shot, to be at a certain angle to impart spin, control the release point of the ball out of the pocket, or exert more force on the ball as it exits the head. With many conventional pockets, however, it is frequently difficult to accommodate these player preferences without significant knowledge and experience about how to modify the net so that the pocket has a specific profile and performs as desired.
In addition, when a conventional pocket wears out, the mere thought of replacing it can be daunting to many, particularly younger or less experienced lacrosse players. This is true for traditional pockets, which include a complicated arrangement of thongs and lacing, and in many cases mesh pockets, which include a soft fabric mesh material that is carefully attached directly to the lacrosse. The reason many players dread replacing or servicing pockets is because most pockets require a complex lacing procedure, which is mastered by only a limited number of individuals, to secure the net to a lacrosse frame in a desired pocket configuration. Thus, many lacrosse players, particularly youths and newcomers to the sport, are left at the mercy of having to wait for their lacrosse sticks to be restrung by someone else, and even then, after the pocket is strung, it usually takes several weeks or months until the pocket is properly broken in to achieve a desired profile.
In addition to conventional lacrosse pockets being difficult to customize and replace, they usually are affected by climate and moisture. For example, even where a pocket net is woven or otherwise constructed from filaments of nylon or polypropylene, when wetted by a rain, the net of the pocket can expand or become slippery, and when dried after being wetted the net can shrink, both of which can significantly alter how a lacrosse ball is shot from the pocket. This can lead to inconsistent shooting, which can be detrimental to the player's performance.
Some manufacturers have attempted to resolve the above issues. One approach is implemented in a pocket called the deBeer Gripper Pro, commercially available from J. deBeer & Son of Altamont, N.Y. The technology of this pocket is presented in U.S. Pat. No. 7,524,253 to Gait, which generally describes a pre-formed pocket including runners having two layers of multiple types of different materials and perpendicular cross pieces strung between the runners. A first layer includes a polyurethane material that is joined with a braided nylon web. A second layer also includes a polyurethane material joined with another braided nylon web. The first and second layers are sandwiched and machine stitched together in some areas, but separated in other areas to form openings between the layers. The openings are large enough so that the cross pieces can be loosely inserted through them. The cross pieces or other laces are then laced through openings in the lacrosse head frame.
While this construction provides an easy-to-install runner system, it requires a skill to precisely position and connect the cross pieces to the multilayered runners, which skill may not be possessed by younger or inexperienced players. Moreover, although the polyurethane and braided nylon layers work well, the layering of different materials requires additional assembly time. The extra machine stitching and sewing to join the various layers also requires additional assembly time and resources.
Another attempt to resolve the above issues with conventional pockets is presented in U.S. Pat. No. 7,192,369 to Morrow, which discloses in one embodiment a mesh pocket integrally formed with a lacrosse head frame. The mesh and head are constructed from the same plastic material, with the mesh and head being portions a single, injection molded item. While this construction eliminates the connection issues between the head and pocket, the pocket material generally is of the same rigidity and has the same characteristics as the head material, which might not be desirable to all players. Further, these “hard pockets” usually do not have sufficient flexibility and sometimes cannot retain a lacrosse ball in the pocket well.
A lacrosse head is provided including a lacrosse pocket that is durable and provides desirable playing characteristics. The pocket is easy to manufacture, and optionally easy to replace and/or service. A method for making the pocket also is provided.
In one embodiment, the pocket is molded and formed to mimic an open mesh or other pocket construction. This molded pocket is dimensioned to fit within the open area of a lacrosse head, generally within the area surrounded by a lacrosse head frame sidewalls, scoop and ball stop. The molded pocket includes a network of multiple individual molded strings constructed of varying cross sections. The cross sections vary throughout different zones of the molded pocket to increase ball control and throwing consistency.
In another embodiment, the multiple joined, individual molded strings of the molded pocket are joined with one another to form fused or combined molded strings, and generally oriented to define pocket holes through the molded pocket. The molded strings and combined strings can vary in cross section about different subsets of the pocket holes located in different zones. For example, molded strings and combined strings in a first pocket zone around the pocket perimeter, near the frame, can be of a first cross section. Additional molded strings and combined strings in a second zone, in the upper part of the pocket near the scoop, can be of the first cross section as well. Other molded strings and combined strings in a third zone, in a transition portion of the pocket, where the ball rolls or moves from the middle of the pocket into the upper part of the pocket toward the scoop, or from the middle of the pocket toward the ball stop, can have a second cross section that is less than the first cross section. Yet other molded strings and combined strings in a fourth zone formed in the middle of the pocket can have a third cross section that is less than the second cross section. The varying cross sections of the molded strings can enable the different zones of the molded pocket to function differently based on their intended function and desired play characteristics.
In still another embodiment, the pocket holes can vary with, or independent of, the molded individual and combined string cross sections, from zone to zone within the molded pocket, to increase ball control and throwing consistency. For example, in the second zone in the upper part of the pocket near the scoop, the pocket holes can be made up of holes of a first dimension. Other pocket holes in a third zone, in the transition portion of the pocket, can be of a second dimension that is greater than the first dimension. In this zone, there can be, for example, 6 to 10, or 8 holes across the molded pocket. Yet other pocket holes in the fourth zone in the middle of the pocket can have a third dimension that is greater than the first and second dimensions. In this zone, where the ball is typically carried, there can be, for example, 4 to 8, or 6 holes across the molded pocket. The varying cross sections of the molded strings can enable the different zones of the molded pocket to function differently based on their intended function and desired play characteristics.
In yet another embodiment, the molded pocket can include molded strings that smoothly transition between different cross sections in different parts or zones of the molded pocket. For example, an individual molded string or combined string can include a first part, a transition part and a second part. The transition part can be located directly between the first and second parts. The first part can have a first cross section, and the second part can have a greater second cross section. The transition part can include multiple varying cross sections sized between the first and second cross sections. The transition part can include an exterior surface having a taper of increasing size from the first part to the second part. The taper can be of a frustoconical, conical, polygonal, or other tapering geometric shape so that the first part transitions to the second part, generally void of any abrupt bumps or steps between the two parts.
In still yet another embodiment, the molded pocket can include pocket holes that are longer in a pocket hole length dimension, which is aligned with a longitudinal axis of the lacrosse head leading from ball stop to scoop, than a pocket hole width dimension, which is generally transverse or perpendicular to the longitudinal axis. In this construction, the molded strings surrounding the holes can generally form hole units, which have broad sides on opposing sides of the length dimensions of the pocket holes.
In a further embodiment, the molded pocket having the hole units with broad sides can be positioned so that multiple broad sides of hole units abut one another across the width of the molded pocket. The broad sides of certain perimeter hole units also can be positioned so that the broad side, and the associated molded string forming that side, is immediately adjacent the outer lateral perimeter or support rail of the molded pocket, a lateral side of a pocket frame to which the molded pocket is joined, and/or a lower sidewall rail of the lacrosse head. With the broad side of the perimeter hole units in this location, the molded pocket can be attached to the structural portions of the molded pocket and/or the head in a consistent and strength enhancing manner. This can improve the connection between the molded pocket as well as the structural longevity of the molded pocket.
In still a further embodiment, the molded pocket can include a shooting channel. The shooting channel can extend generally from the middle portion of the pocket or the fourth zone as mentioned above, through the third zone, in the transition portion of the pocket, and out through the second zone in the upper part of the pocket near the scoop. Throughout these zones, the shooting channel can have varying widths and heights progressing from the middle of the pocket to the upper part of the pocket near the scoop.
In still yet a further embodiment, the shooting channel can include decreasing widths and depths that are molded directly into the molded pocket and reflected in the molded strings as the channel progresses from the middle of the pocket to the upper part of the pocket near the scoop.
In another further embodiment, the molded pocket can include molded shooting strings molded directly to the other molded strings in the pocket, for example the individual molded strings and/or the combined strings. The shooting strings can extend laterally across the molded pocket from near one sidewall toward an opposing sidewall, near the scoop. The molded shooting strings can be integrally formed and monolithic with the molded strings and hole units. The molded shooting strings can have rounded, angled or flat upper surfaces facing into the molded pocket, generally upward into the area where the ball is held or moves within the pocket. The molded shooting strings can also have an arced, parabolic or rounded shape when viewed from the top side of the head, so that they form a generally convex shape when viewed from above the head, and from a perspective view from the scoop toward the ball stop along the longitudinal axis of the head.
In yet another further embodiment, the molded pocket, or alternatively a fabric mesh or other traditional pocket, can be joined with a pocket frame, which is further joined with the lacrosse head. The pocket frame can define one or more grooves around the perimeter of the frame. The grooves can be located in areas which, when the pocket frame is joined with the lacrosse head, correspond to the ball stop, sidewalls and/or scoop. The molded pocket or other pocket can be received in the groove to secure the pocket to the pocket frame. The pocket frame can include an inner part and an outer part that sandwich a perimeter of the molded pocket or other pocket there between, generally within the groove.
In another embodiment, the pocket frame can be joined with the head frame by molding the head frame over the pocket frame. The pocket frame can include ridges, projections, or other connection enhancing structure extending from surfaces thereof to enhance the physical connection between the pocket frame and the head frame. The pocket frame can be molded over by material of the head frame in the ball stop, sidewalls and/or scoop of the head frame. Optionally, the material of the pocket frame can be a different material from the material of the head frame and the molded pocket as well.
In even another embodiment, the molded pocket and its components can be constructed from a polymeric material, for example, thermoplastic elastomer polymers, such as thermoplastic polyurethane (TPU), thermoplastic copolyester, thermoplastic polyamides, polyolefin blends, styrenic block polymers, and/or elastomeric alloys, as well as rubber, formable but flexible resins, hydrophobic flexible materials, and/or other similar flexible materials.
In still another embodiment, the pocket frame can define multiple string holes around at least a portion of its periphery. The lacrosse head frame can define a stringing ridge or shoulder. The pocket frame can be sized or contoured to fit within, around, or generally mate with the stringing ridge or shoulder. The molded pocket or other pocket can be attached to the head by a string that passes through string holes defined in the head and through the string holes defined by the pocket frame.
In yet another embodiment, a method for molding a fabric mesh pocket or other pocket is provided. A mold defining a pocket frame mold cavity corresponding to the pocket frame is provided. The mold optionally can include one or more locator pins around a perimeter of the frame, optionally mounted exterior to the outside of pocket frame mold cavity. A standard mesh or synthetic material is stretched laterally and optionally longitudinally above the pocket frame mold cavity. The stretched mesh or synthetic material is moved toward the pocket frame mold cavity and engaged with the locator pins so that the mesh or synthetic material is maintained in a tensioned state, laterally and/or longitudinally, with a portion of it laying across and/or in the pocket frame mold cavity. Polymeric material is introduced into the pocket frame mold cavity with the mesh or synthetic material maintained in the tensioned state, so that the polymeric material is molded around the mesh or synthetic material occupying the pocket frame mold cavity. The polymeric material is allowed to cure and form the pocket frame. The pocket frame is removed from the mold, with the mesh or synthetic material molded within it and attached to it so that it cannot be removed without destroying the pocket frame and/or the mesh or synthetic pocket material.
In still yet another embodiment, the mold defining a pocket frame mold cavity corresponding to the pocket frame includes a central part located along a longitudinal axis of the mold, generally in the middle of pocket to be formed with the mold. The central part includes a bulbous contour that projects upward, above the uppermost part of the pocket frame mold cavity. When the mesh or synthetic material is placed in a tensioned state with the pins and brought near or within the pocket frame mold cavity, the contour can engage the mesh or synthetic material to form it into a corresponding shape. When the pocket frame is ultimately removed from the mold, the attached mesh or synthetic material maintains this corresponding shape. The corresponding shape can be a fitted ball pocket depression within the pocket on the pocket frame within which a lacrosse ball naturally moves toward when it is in the pocket. The particular location of the contour can be selected based on the desired playing characteristics of the lacrosse head to which the pocket frame and pocket are attached. With this depression “pre-formed” in the pocket, minimal break-in time for the pocket can be realized.
In a further embodiment, a mold for molding a molded pocket are provided. The mold can include a base having a base molded pocket cavity forming a first pocket cavity portion corresponding generally to an interior surface of the molded pocket (facing inward, toward the interior of the head or pocket frame) and an axis of symmetry generally corresponding to a longitudinal axis or some other preselected axis of the molded pocket. The mold cavity can include a retainer portion that captures an already formed lacrosse head or pocket frame, and places it immediately adjacent the mold cavity in which the mold pocket is to be molded. Where the mold pocket is to be molded to the head or pocket frame, the retainer can perfectly align the lacrosse head or pocket frame with the mold cavity and any gates or other features of the mold.
In still a further embodiment, the mold can include at least two slides disposed generally opposite one another, optionally on opposite sides of the axis of symmetry. The slides collectively can define a second pocket cavity portion of the molded pocket cavity, which generally corresponds to the exterior surface of the molded pocket (facing outward, away from the head or pocket frame). The slides can be operable to close against the mold base so that the first pocket cavity portion and second pocket cavity portion cooperatively form a cavity corresponding to the molded pocket.
In still yet a further embodiment, the at least two slides can each be configured to pivot toward the base about first and second mold pivot axes, optionally disposed opposite from one another across the axis of symmetry. The slides can each fold or swing about the respective axes toward one another to meet at the axis of symmetry and close the mold cavity of the molded pocket. The pivoting or folding slides can be configured to open in an opposite direction, pivoting outward from the molded pocket after the molding operation is complete. Due to the pivoting or folding movement, the first and second slides cleanly release from the multifaceted, complex structures of the molded pocket, for example the hole units and variety of molded strings with their optional varying cross sections.
In even a further embodiment, the first and second mold pivot axes are disposed opposite from one another across the axis of symmetry, and above the lowermost portions of the lacrosse head to which the molded pocket is joined. Optionally, the first and second mold pivot axes are placed above or even with the uppermost portions of the lacrosse head to which the molded pocket is joined. With this spatial orientation of the pivot axes relative to the head and/or the completed molded pocket, the slides fold or pivot away from the base in a manner that allows the first and second slides to cleanly release from the structures of the molded pocket, for example the hole units and molded strings.
In another, further embodiment, a method for molding the molded pocket is provided. In the method, a mold including a base having a base molded pocket cavity forming a first pocket cavity portion and an axis of symmetry is provided. Further provided are first and second slides configured to pivot toward the base about first and second mold pivot axes, where the first and second slides are disposed opposite from one another across an axis of symmetry of the base, and cooperatively define a second pocket cavity portion. A lacrosse head frame or pocket frame is placed in the base adjacent the first pocket cavity portion. The slides are pivoted about the respective axes toward one another to optionally meet at the axis of symmetry and close the mold cavity of the molded pocket. A material is introduced, for example by injection, into the first pocket cavity portion and second pocket cavity portion which form the molded pocket cavity to form a molded pocket. The material engages and/or bonds to the head or pocket frame. The slides are folded open about the axes, with the second pocket cavity portion cleanly releasing from the molded pocket and any associated molded strings or other structures of the pocket, head and/or pocket frame. The molded pocket and associated head or pocket frame are removed from the mold.
The pocket and methods herein can provide a pocket that is virtually unaffected by weather changes, temperature changes and moisture, which enables it to have a substantially consistent profile and configuration throughout such conditions. In turn, this enables the player to play with confidence, even under adverse environmental conditions. The molded pocket can be of a sufficient stiffness to provide more accurate, higher velocity shooting and passing, yet can still be able to adequately cradle, catch and retain a lacrosse ball. In turn, the pocket can be custom built for a variety of different positions in the game of lacrosse. Where it includes a preselected set of contours, the pockets herein require minimal break-in, maintenance and skill for installation on a lacrosse head. The pockets herein also can be less expensive to manufacture and assemble than conventional lacrosse head pockets.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.

A current embodiment of a lacrosse head pocket is shown in
The molded pocket 10 can also define holes 31 which are surrounded substantially by the molded strings 12. These molded strings and holes can form hole units 30. As shown in
As shown in
The pocket 10 also can include a shooting channel 40 as shown in
The various structural components and construction of the current embodiment will now be described. Beginning with
The molded pocket 10 can include a network of multiple molded strings 12 which extend and connect with one another across the pocket along various lateral 101 and longitudinal 102 axes. These molded strings 102 can be of a rounded or circular cross section in areas where adjacent molded strings do not meet up with one another. For example as shown in
Although shown as being of a generally circular or rounded cross section and configuration, any of the molded strings can be of other geometric cross sections as well. For example, they can be square, rectangular, rounded, triangular, polygonal, elliptical or combinations of the foregoing. As a further example, a molded string of the pocket can be flat on the rear side and rounded on the front side or vice versa. The molded strings also can include a variety of different tapers depending on the particular location within the pocket. Further, the individual molded strings or combined molded strings can include different types of textures or surfaces to enhance ball control and grip.
The molded pocket herein can be constructed from a variety of polymeric materials, which include, but are not limited to, elastomeric materials, such as the thermoplastic polymers, thermoplastic polyurethane, thermoplastic resins, thermoplastic copolyesters, thermoplastic polyamides, polyolefin blends, styrenic block polymers, and elastomeric alloys, as well as rubber, formable but flexible resins, hydrophobic flexible materials, or similar flexible materials, or combinations of the foregoing. Where the material is hydrophobic, the single layer runners and the resulting pocket can be resistant to shrinkage or shape alteration due to moisture, and in many cases changes in ambient temperature. Optionally, the entire structure of the molded pocket is formed from a single, monolithic piece of polymeric material, having different thicknesses and cross section areas of molded strings, rails or other components as desired.
As shown in
The shooters 19 can extend laterally across the lacrosse head generally extending from a first sidewall 24 to a second sidewall 26. The shooters 19 can also be structured to form a rounded or arc, which when viewed from the top of the head 20, form a generally concave structure, travelling from the scoop 28 toward the ball stop 23 along the longitudinal axis 102, or a concave structure going the opposite direction along the longitudinal axis. One or more shooters, whether intertwined with one another, can be spaced from one another approximately ¼ inch to 1¾ inch, ½ inch to 1½ inch, and/or ¾ inch to 1 inch. Other ranges can be selected depending on the particular desired characteristics of the pocket, and the position in which the pocket will be used, for example in an attack position, a midfield position or a defense position. As shown in
Within the molded pocket 10, the hole units 30 also can be aligned in an arced, rounded and/or parabolic configuration extending laterally from the first sidewall 24 to the second sidewall 26 on the head. Generally, the hole units 30, holes 31 and shooters 19 can be aligned along a curved axis 103 defined in the shooting ramp of the molded pocket.
Optionally, the hole units 30 as shown can be constructed to define holes 31. These holes as shown are in the form of a hexagonal shape. Of course, it is to be appreciated that the shape may vary. For example, the holes can be of an elliptical, circular, triangular, polygonal, octagonal, or other shape depending on the particular application and the zone or portion of the pocket within which the holes are defined and the respective hole units are located.
The molded pocket 10 can include additional components to facilitate attachment of the individual molded strings, the combined strings and/or the shooters to the head 20, and in particular its components such as the sidewalls 24, 26, the ball stop 23 and the scoop 28. For example, the molded pocket can include one or more support rails around all or a portion of its perimeter 15 also referred to as an upper perimeter. As shown in
The sidewall support rails 14 and 16 can be integrally and monolithically molded with the individual strings, combined strings and/or shooting strings, or any other component of the molded pocket and constructed from the same material. Of course, the rails alternatively can be constructed from another material having a different durometer to provide enhanced or different rigidity and strength at the locations where the rails attach the molded pocket to the head.
Returning to
Optionally, each of the sidewall rails 14 and 16 and the ball stop rail can be configured to interfit within a shoulder or stringing ridge defined by the bottom edge of the head, generally through the ball stop and sidewalls, as further described below. These rails can be configured to perfectly fill the stringing ridge, so that their outermost surface facing the interior 22 of the head is flush with the interior surface of the sidewalls and ball stop. Of course, if desired, the rails can be offset or not flush with these surfaces, in which case they can be inwardly or outwardly set relative to the respective surfaces of the head facing the interior 22.
The molded pocket can also include a forward scoop support rail 18 that can also be integrally formed and monolithic with the remainder of the molded pocket, including the network of individual strings, combined strings, and/or shooting strings. As shown in
As shown in
The molded pocket can be divided into different zones as shown in
Zone Z1 is a zone that extends around the periphery 15 of the pocket. Where the pocket 10 is a molded pocket, the zone Z1 immediately adjacent the periphery 15 of the interior 22 of the head, generally immediately adjacent the ball stop 23, sidewalls 24 and 26, and the scoop 28 of the head, can be formed from molded strings having a first cross section D2. For example, the individual molded strings can have a first cross section D2 ranging optionally from about 1 mm2 to about 4 mm2, further optionally about 2 mm2 to about 3 mm2, and even further optionally about 1.5 mm2. The particular cross section of the molded strings in this zone can be selected so that around the perimeter, the molded pocket is fairly rigid and inflexible. This can enhance the attachment of the molded pocket around the periphery 15 of the pocket to the head 20. As explained below, the molded strings in this zone can also be constructed and include cross sections that merge and transition well into the support rails in the various regions of the molded pocket, for example the balls stop support rail 13, the sidewall support rails 14 and 16, and the scoop support rail 18. In some cases, however, the molded strings in this zone Z1, particularly near the ball stop and sidewalls, can be replaced entirely by the respective support rails 13, 14 and 16, or portions thereof, if desired.
Zone Z2 of the molded pocket 10 is located immediately adjacent the scoop 28 and extends laterally from one sidewall 14 to the opposing sidewall 16, or generally from a first side of the scoop 28 to a second, opposite side of the scoop 28. This zone Z2 optionally can have molded strings of the first cross section D2, like that described above in connection with zone 1. Of course, zones Z1 and Z2 can have different cross sections as well if desired. For example, where the individual molded strings, shooters or combined strings in zone Z1 connect directly to sidewalls, scoop and/or ball stop of the lacrosse head, those molded strings in zone Z1 can be of a larger cross section than the cross section of the molded strings in zone Z2.
As shown in
Of course, these cross sectional areas can vary, as can the other cross sections described herein, depending on the desired characteristics of the molded pocket. Further, the order of cross section can be altered depending on the particular play of the head. For example, the zone Z3 can be constructed from molded strings that are actually of a larger cross section the molded strings in zone Z2. Generally, however, the cross sections of molded strings in zone Z4 are less than the cross sections of molded strings in zones Z1, Z2 and Z3 to enhance the cradling capability of the ball and securely hold it or otherwise allow it to nest in the middle of the pocket in zone Z4.
Returning to zone Z3 shown in
The outermost lateral regions Z3B and Z3C of zone Z3 can include molded strings that transition immediately to the molded strings of the first zone Z1. The molded strings generally can increase in cross sectional area as described below. Further, at these lateral transition regions, as well as at the longitudinal transition regions between the forward edge Z3F and zone Z2, the rearward edge Z3R and zone 4, the molded strings, for example, the individual molded strings, shooters or combined strings can form or include a transition part as described below.
Optionally, near the ball stop 23, the molded pocket 10 can include another third zone Z3A which can include molded strings that are of the same or similar second cross section D3 as the region Z3. This zone Z3A can include a rearward portion Z3D and a forward portion Z3E. Both of these portions can be generally arcuate, parabolic and/or rounded. The rearward portion Z3D can transition directly to the zone Z1 around the perimeter of the pocket 10 and/or a support rails in the ball stop and/or sidewalls if included. The forward edge Z3E of the zone Z3A can likewise be of an arcuate, parabolic and/or rounded as well, and generally of a concave shape when transitioning along the longitudinal axis from the scoop 28 toward the ball stop 23. Generally, when referring to zone Z3, this also can refer to zone Z3A.
As described below, in the transition regions between zone Z3 or Z3A to zone Z4, the molded strings can include transitions parts. As shown in
Zone Z4 is generally located in the middle of the pocket. The individual shooting strings, combined strings and/or shooters, if any are included in this region, can include cross sections that can be of a third cross section D4 that is less than the molded string second cross section area D3 in zones Z3A and Z3, and also less than the molded string first cross section D2 in zone Z2 and optionally Z1. In zone Z4, for example, the molded strings can have a third cross section area D4 ranging optionally from about 0.25 mm2 to about 2 mm2, further optionally about 0.5 mm2 to about 1 mm2, and even further optionally about 0.75 mm2. The particular cross section of the molded strings in this zone can be selected so that the zone Z4 is generally somewhat flexible and deformable, at least more so than the zones Z3, Z2 and Z1, which are designed to have slightly more rigidity and structural resistance to deformation when a ball contacts those zones. For example, the strings in zone Z4 can be configured so that when a player is cradling a ball in that section, the ball engages the softer, optionally more elastic molded strings in that region to better retain and hold the lacrosse ball within the molded pocket 10.
As shown in
Further optionally, the molded pocket can be constructed from an elastomeric material that is stretchable when a force is exerted upon it, such as the centripetal force F1, or some other force, so that the molded pocket temporarily and elastically deforms or stretches to provide the desired increased pocket depth D1 as shown in
In applications where the molded pocket is constructed from elastomeric material, when that elastomeric material stretches upon application of the force and movement of the ball deeper in the pocket, the molded strings in zones Z4 and Z3 can clamp laterally inward on the ball B, generally toward the longitudinal axis of the head. This can provide additional grip to capture and retain the ball in the pocket.
More particularly, as shown in
To achieve the particular functional attributes noted above, for example the flexibility in the middle of the pocket or rigidity around the perimeter or in the shooting ramp, the molded strings can be of the different cross sections in the different zones Z1, Z2, Z3 and Z4 or other zones of the head. Of course, additional or fewer zones can be included in the molded pocket 20. Optionally, however, to provide the different functional attributes in the different zones, instead of or in addition to varying the cross section areas, the durometer of the materials from which the molded pocket and molded strings are constructed can vary.
For example in zone Z4, the molded strings can be constructed from an elastomeric and/or polymeric material having a durometer ranging from optionally about 1 to 50 on Rockwell C, further optionally about 5 to 35 on Rockwell C, and even further optionally about 10 to 25 on Rockwell C. In zone Z3, leading from the middle portion of the pocket to zone Z2 near the scoop, the molded strings can be constructed from an elastomeric and/or polymeric material having a durometer ranging from about optionally about 30 to 70 on Rockwell C, further optionally about 40 to 60 on Rockwell C, and even further optionally about 45 to 50 on Rockwell C. In zone Z2 nearest the scoop, and zone Z1 around the perimeter, the molded strings can be constructed from an elastomeric and/or polymeric material having a durometer ranging from about optionally about 50 to 90 on Rockwell C, further optionally about 60 to 80 on Rockwell C, and even further optionally about 70 on Rockwell C. Of course, the aforementioned material properties, and in particular the durometers or hardnesses of the molded pocket and its components can vary in different zones or regions, other than those specifically illustrated in
Optionally, the dimensions, shapes and/or number of the holes 31 and/or hole units 30 also can vary to provide the desired functional attributes of the molded pocket throughout the different zones Z1, Z2, Z3 and Z4, or different regions of the pocket. For example as shown in
In zone Z2, the pocket holes 30 and/or hole units 31 can number such that there are 8, 10, 12, 14, 16, 18 or 20 of them laterally from one sidewall 24 to the other sidewall 26. In zone Z3, the pocket holes 30 and/or hole units 31 can number such that there are 6, 8, 10, 12, 14 or 16 of them laterally from one sidewall to the other sidewall. In zone Z4 the pocket holes 30 and/or hole units 31 can number such that there are 4, 6, 8, or 10 of them laterally from one sidewall to the other sidewall. Further optionally in the zone Z3, there optionally can be 6, 10, or further optionally 8, holes or hole units laterally from one sidewall to the other. In the zone Z4, there optionally can be 4, 8 or further optionally 6 holes or hole units laterally from one sidewall to the other. The above number of holes can vary depending on the desired functional attributes of the pocket and/or player position. In some cases, the number of hole units and/or holes can be consistent and the same in all the different zones, and can have a generally uniform dimension across all the zones if desired.
As mentioned above, the molded strings can have varying cross section areas, where one part of the string transitions to another part of the string having a different cross section area. For example, turning to
The first part of the molded string 12E can be constructed to include a total cross section area TCS1. The second part 12F can include a total cross section area TCS3. The total cross section area TCS1 can be greater than the total cross section area TCS3 or vice versa. For example, the total cross section area TCS1 in
The overall geometric shapes of the respective cross section areas in parts 12E and 12F can be the same or they can be different. For example, the first part 12E can have a large circular or rounded cross section area TCS1 and the cross section area TCS3 of the second part 12F can be of a like or similar cross section. Alternatively, the first cross section area TCS1 can be square and the second cross section area TCS3 can be round or oval. The different cross sections can be mixed and matched, depending on the particular application and desired contact between the molded strings and the lacrosse ball within the molded pocket.
As shown in
Optionally, the transition part 12T can have a cross section area of the same shape, or a different shape, as the cross section areas of the first and second parts. For example, the first part 12E can have a cross section area TCS1 of a circular shape, the transition part 12T can have a cross section area TCS2 of an oval shape, and the second part 12F can have a cross section area TCS3 of a round or square shape. The geometric shapes and the cross section areas throughout the first part, second part and transition part can vary, again depending on the desired properties of the string.
Generally, the transition part 12T can have a frustoconical shape when viewed from a top or side view as shown in
The transition part 12T can be implemented with the molded strings or components of the molded pocket to provide a smooth transition between first and second parts of the pocket of varying cross sections. The transition part 12T generally provides a non-abrupt, non-stepped transition between different parts so that a ball within a lacrosse pocket can smoothly roll across the molded string surfaces facing toward the interior of the pocket. Of course, in certain applications, integral steps or abrupt transitions can be integrated into the transition part 12T between different first and second parts as desired.

Generally, the different hole units 30A, 30B and 30C include broadsides 33A, 33B and 33C that are configured for attachment to the support rails 13, 14, 16 and/or 18 or other components of the pocket that connect directly or indirectly to the head 10. Alternatively, these broadsides 33A, 33B and 33C can connect directly to the lacrosse head itself in certain constructions, or to strings or laces that are strung to the head, or to a pocket frame as described below.
The hole units 30A, 30B and 30C are constructed so that the longitudinal dimensions 30L are greater than the lateral width dimensions 30W of each of the respective holes 31A, 31B and 31C and/or hole units 30A, 30B and 30C. These widths and lengths are generally aligned with and/or parallel to the lateral axis 101 and longitudinal axis 102 (
The lengths 30L and widths 30W of the hole units can be measured from the innermost perimeter of holes 31A-31C of the hole units. The precise ratio of the length to the width for the broadside hole units can vary depending on the particular application. For example as shown in
With regard to hole units 30A, 30B and 30C positioned near the perimeter 15 of the pocket 10, the broadsides of those perimeter hole units optionally can be positioned so that the associated individual molded strings, combined strings and/or shooters are immediately adjacent a support rail of the pocket, a lateral side of the frame to which the pocket is joined, a lower sidewall rail of the lacrosse head, and/or the scoop. Perimeter hole units having this broadside construction can be attached to structural portions of the molded pocket and/or the head in a consistent strength enhancing manner. This can reduce and/or eliminate tearing of the molded pocket adjacent the support rail and/or head component. In some cases, this type of broadside attachment also can enhance the elasticity of the molded pocket, and in particular the hole units, in these regions. In turn, this can provide enhanced flexibility and/or rigidity, depending on the particular construction in these locations. Further, when coupled the increased cross section area of molded strings, the use of broadsides in hole units can enhance the rigidity and strength of the molded pocket near the perimeter.
Optionally, the hole units 30A, 30B and 30C shown in
As shown in
Generally, the ball channel 40 can be implemented in the molded pocket 10 so that it extends from the middle portion M of the molded pocket 10, through the ramp R, toward the scoop 28. The particular locations of the middle portion of the pocket M and the ramp R can vary depending on the particular construction of the molded pocket. Optionally, the middle portion M can be at and/or near the part of the pocket at which an apex AP (
Although shown as generally being separated along the entire longitudinally axis 102 from one another by the ball channel 40, the flanks 50A and 50B can join one another, forward of the ball channel 40 near the scoop 28. The flanks also can extend through the ramp leading from the middle of a pocket M toward the scoop. The flanks can terminate adjacent the middle portion of the pocket M, which can correspond to the zone Z4 shown in
The flanks can be generally flat and planar as shown, or can include a slight or significant curvature extending from the channel 40 to the perimeter 15 of the molded pocket on opposing sides, near the sidewalls 14 and 16 of the head 20. Optionally, the flanks can be concave upwardly or convex upwardly, into the interior 22 of the head 20. The flanks, along with the ball channel, can all be constructed as integral parts of the molded pocket 10, including any of the features explained in the embodiments herein. For example, the network of molded strings 12 and any associated shooting strings or other parts can be monolithically and integrally formed with one another from a polymeric material to form a single piece unit, spanning across the flanks and ball channel, as well as the ramp and middle portion of the pocket.
Optionally, where the flanks, ball channel, middle portion of the pocket and ramp are all part of the molded pocket, and the pocket is constructed from an elastomeric material, these components can remain in a somewhat fixed, static configuration, in which they are all consistently and semi-rigidly held in a desired spatial configuration. However, given the elastic and stretching properties of the elastomeric material, these components can flex or stretch out of the static configuration to a dynamic configuration, and then return to the static configuration after a particular head manipulation is performed. For example, when a lacrosse ball is shot out the ball channel 40 from the middle portion of the pocket M along the ramp R, all of these components can flex or stretch, and more particularly, the molded strings and shooters of these components can elongate, stretch, compress or otherwise deform. When this occurs, the channel and flanks, and ramp and/or middle of the pocket can change their spatial orientation from one another, in some cases, changing temporarily the angles of these components relative to one another, the dimensions of the respective components, and the general distances between the components and/or the sidewall, scoop and/or base of the head.
The flanks can include portions of the shooters 19 if desired. The shooters 19 can extend through the first flank 50A, the ball channel 40, and out toward the opposing sidewall along the flank 50B. The shooters 19 themselves can be depressed, recessed or warped generally along their central region near the longitudinal axis 102, and can extend downwardly into the ball channel 40, as described below.
Returning to
The ball channel 40 can be centered on the longitudinal axis 102 of the head. In some cases, however, the ball channel 40 can be offset laterally toward one sidewall 14 or the other sidewall 16. The offset angle of approach toward the scoop can vary from being parallel with the longitudinal axis 102. For example, the ball channel can have an axis 40LA that is offset at some angle α4 from the longitudinal axis 102. This angle α4 can be about 1°, 5°, 10°, 15°, 20° or other angles as desired. Further, it can be offset either direction, laterally of the longitudinal axis 102.
As shown in
Generally the ball channel 40 can be contoured so that the contours C1-C4 are of a decreasing depth D1-D4, and increasing width W1-W4. As illustrated, these contours are generally of a U, V, sideways C shape, or parabolic shape, concave upwardly toward the upper side of the lacrosse head. The contours can include maximum depths and maximum widths. Measured from the interior 22 of the head, the depths generally extend from the upper surface of the molded pocket immediately adjacent the contours, downward to the lowermost portion of the contours. The depths also can vary increasingly from near the scoop 28 toward the ball stop 23 or the middle of pocket M.
For example, the contours C1, C2, C3 and C4 can be of an increasing depth from the scoop to the middle M of the pocket. The variance in the depths of the ball channel 40 along the contours can be such that depth D4 of contour C4 is optionally about 1, 2, 3, 4, 5, 10, 15, 20, or 25 times greater than depth D1 of contour C1. The depths D1-D4 can also vary depending on the position of the player using the molded pocket, and/or depending on the desired location of the apex AP of the pocket, that is, the deepest part of the molded pocket from scoop 28 to base 23. For example, the apex can be located high near the scoop, in the middle about midway between the scoop and the ball stop, or low, that is, near the ball stop of the head. Depending on the locations of the apex, the depths D1-D4 can vary, and optionally all can generally increase from the scoop toward the apex of the pocket and/or the middle portion M of the pocket.
The contours C1-C4 of the ball channel can include widths W1-W4 that vary from the scoop toward the apex of the pocket and/or the middle M of the pocket, generally in an increasing manner. The variance between the width W1 of the contour C1 relative to that of the width W4 at contour C4 can be such that width W4 is optionally about 1, 2, 3, 4, 5, 10, 15, 20, or 25 times greater than width W1 at contour C1. Optionally, widths W1-W4 can generally increase from the scoop toward the apex of the pocket and/or the middle M of the pocket. Further optionally, the contours can be configured so that the contours near the middle portion of the pocket have a first width, and the contours near the scoop have a second width that is at least one of less than, greater than, and/or the same as the first width.
Referring to
Optionally, as shown in
As mentioned above, the shooting strings 19 can traverse the hole units 30 in the molded pocket 10. Accordingly, in some cases, where the shooting strings 19 traverse hole units within the ball channel 40, the combined shooting strings and hole units, and corresponding individual strings or combined strings, can also be incorporated into a monolithic structure having the shooting contour SC.
Optionally, the shooting contour SC, or any other contour C1-C4 for that matter, can be shaped so that the components of the pocket on opposite sides of the longitudinal axis 102 are identical and symmetrically located about the axis to impart consistent spin and/or forces on a lacrosse ball contacting the components on opposite sides of longitudinal axis 102 as that lacrosse ball traverses along the ball channel 40. For example, if there is a hole unit disposed in the shooting contour SC or any of the other contours C1-C4, that hole unit can be positioned so that it is symmetric across the longitudinal axis 102. Alternatively, the first and second hole units can be positioned immediately adjacent one another, but on opposite sides of the longitudinal axis 102. In this manner, the longitudinal axis 102 generally dissects the individual molded string or the combined string along the axis 102.
As mentioned above, the ball channel and location of the apex, or corresponding deepest depth of the pocket, can vary for players using a head in an attack position, a midfield position, or a defense position. For use in an attack position, the ball channel 40 can be relatively well defined, having a lower (toward and the ball stop) pocket apex with a long center channel length (a long ramp). The ball channel 40 also can be “deeper” from the middle M of the pocket, where the ball is typically cradled or held, through the ramp R and out toward the scoop 28 of the head. As an example, with reference to
For use in a midfield position, the pocket can include a ball or shooting channel and an apex placed in the middle of the pocket, for example, midway between the ball stop and the scoop. The shooting channel 40 can be a mid-center length channel for better control. As an example, with reference to
For use in a defense position, the pocket can include an apex placed high on the pocket, toward the scoop, and a short shooting or center channel (a short ramp). For example, the apex can be located between the midway (located between the ball stop and the scoop), and the scoop. As a further example, with reference to
Examples of dimensions or maximum depths for particular pockets, that is high pockets, mid pockets and low pockets, in the respective zones are presented in Table 1 below.
The construction of the ball channel, shooting ramp, apex and other features of the molded pocket 10, when configured for use in one or more positions, for example, attack, midfield and defense positions, as well as goalie positions, for both men's and women's lacrosse heads, is better understood with reference to
As shown there, the molded pocket 40 generally includes the middle portion M which transitions to a shooting ramp R. The ball channel 40 can extend within at least the ramp R and can be generally flanked on opposite sides through the ramp by flanks 50A and 50B as described above. As shown in
Generally, the rounded bottom 42B can transition to the pocket walls 50S. The pocket walls 50S can be planar, or have a rounded shape with a significantly larger radius than that of the rounded bottom 42B. Where the transition occurs, or generally where the rounded bottom 42B intersects or merges into the pocket walls, the pocket walls can project substantially at an wall angle B1 or B2 away from the end or boundary of the rounded bottom 42. The wall angles B1 and B2 can be measured relative to a vertical plane VP that is parallel to and laterally offset from the longitudinal axis 102 and that passes through the intersection of the rounded bottom 42B and the respective pocket wall 50S.
The radii of the rounded bottom and the wall angles can vary depending on the applications. Various optional values for wall angles B1 and B2, first width curvature and radius RB, and second width curvature and radius RC, used in connection with virtually any head used in any position, are illustrated in Table 2 below.
With further reference to
Generally, the rounded ball channel 40 transitions to the flanks 50A and 50B at the optional shoulders 41S as described herein. Where the transition occurs, or generally at or near the shoulders 41S, the pocket walls can project substantially at flank angles B3, B4 away from the end or boundary of the ball channel 40 or shooting contour SC. The flank angles B3 and B4 can be measured relative to a vertical plane VP that is parallel to the longitudinal axis 102 and that passes through the intersection of the ball channel 40 or shooting contour SC and the respective flank 50A or 50B, optionally at the shoulder 41S. In this configuration at the cross section taken in
The radii of the ball channel and shooting contour, as well as the flank angles can vary depending on the application. The side-to-side width curvatures of the ball channel and/or shooting contour and the flank angles as well can. Various optional values for the flank angles B3 and B4, and the curvatures of the ball channel RD and RE used in connection with virtually any head used in any position, are illustrated in Table 3 below.
With reference to
The pocket bottom 42B can be generally rounded along a direction from the base 23 to the scoop 28, as shown in the cross section taken in
As shown in
At its rear, near the base 23, the rounded bottom 42B can transition to a rear pocket wall 50R. This wall 50R can be contiguous with the pocket walls 50S, and can cleanly merge into them. The rear pocket wall can extend generally toward the base 23 or ball stop depending on its precise location. The rear portion of the bottom 42B also can transition to the rear pocket wall at a transition location 50T. At this transition location, the rear pocket wall can be disposed at a rear pocket wall angle B5. This angle B5 can be taken at the point or along a line where the bottom 42B transitions to the rear pocket wall, and can be taken relative to the first horizontal axis HA1 (or some other horizontal axis) that runs generally parallel to and optionally below the longitudinal axis 102.
The first and second curvatures, respective radii, shooting ramp angles and rear pocket wall angles can vary depending on the application. Various optional values for ramp angle B6, rear pocket wall angle B5, first curvature and radius RG, and second curvature and radius RF used in connection with virtually any head used in any position, are illustrated in Table 4 below.
A first alternative embodiment of the lacrosse pocket is illustrated in
Generally, the pocket 110 can include the individual molded strings, combined molded strings, shooters, rails and other components as described in connection with the embodiments above. The pocket frame 60 can be constructed so as to be rigidly and consistently attached to the pocket. For example, as shown in
The inner part 61 and outer part 62 also can include a structural protuberance or projection 61B and 62B extending laterally outward away from the exterior surfaces of the inner and outer parts 61 and 62 respectively. The projections as shown can be of a semicircular geometric configuration. Alternatively, they can be of another geometric configuration, for example, they can be triangular, polygonal, rectangular, square, trapezoidal or combinations of the foregoing. Moreover, the projections 61B and 62B can be duplicated on the exterior surfaces of the parts, and instead of being a single projection can extend in multiple places from the top 65 to the bottom 64 of the pocket frame along the parts 61 and 62. Of course, these projections 61B and 62B can also be formed as elongated ridges that extend around the entire pocket frame 60 generally facing the interior 22 as shown in
Returning to
Returning to
The support rail 118 can be encapsulated, embedded or otherwise trapped within the groove 63 of the pocket frame 60. Specifically, the support rail 118 can include inner 118A and outer 118B surfaces. These surfaces can be bonded directly to the interior of the groove 63, for example directly to the surfaces 61A and 62A. Although not shown, the surfaces 61A and 62A can include one or more recesses or ridges, or holes or projections to further enhance the mechanical bonding of the support rail 118 to the pocket frame 60.
Optionally, the support rail 118 can extend a distance D5 outward and below the bottom 64 of the pocket frame 60. This distance can vary depending on the particular flexibility of the molded support rail after it is completed. In some cases, the support rail can extend a distance D5 that is optionally about 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or 10 mm below the bottom 64 of the pocket frame 60. In some cases, the support rail can be configured so that it does not extend beyond the bottom 64 of the pocket frame 60, in which case distance D5 can be zero.
In the embodiment shown in
If desired, the T-shaped end 118c can be eliminated or modified, with the top of the support rail terminating at an end that is the same width as the remainder of the support rail. This end may or may not be encapsulated or covered by an overlaying portion of the frame. Although not shown, the T-shaped end can be replaced with an L-shaped end which includes a lateral flange that overlaps only the first part or the second part. Further, the support rail 118 can be configured so that in some portion of the rail around the perimeter of the head, the T-shaped end 118c is included, but in other areas it is not. The areas it is located can correspond to those where the pocket encounters forces that might pull the pocket away from the frame. Optionally, the lateral members in different areas can be thickened or thinned, and can extend different distances or thicknesses from the top 65 of the frame pocket 60. These different thicknesses can be fine tuned to the particular location in the head in which particular characteristics are desired.
Turning to
As shown in
In this construction, the pocket frame 60 can be sandwiched between the part of the rail including the inner surface 26A and the outer part of the rail including the outer surface 26E. The top of the pocket frame 65 may or may not extend through or beyond the upper surface 26F of the lower rail, depending on the attachment of the molded pocket and pocket frame to the sidewall or other component. Although the aforementioned is described in connection with the lower rail 26A of the sidewall 26, it can also be applied to the ball stop, opposing sidewall and/or scoop or other features of the lacrosse head.
Optionally, as shown in
A method for making the first alternative embodiment of the lacrosse pocket including the pocket frame will now be described. In general, that method includes molding the pocket frame 60 out of a first material, such as a polymeric material, or even a metal or composite. The pocket frame 60 can be molded to include the scoop member 68 joined with opposing sidewall members 65 and 66, which are further joined with a ball stop member 67. The frame 60 can define a groove 63 through all of these different members. The groove can include the features described above.
With the pocket frame molded, the pocket can be molded directly to the pocket frame. The pocket frame can include the various components described in connection with
With the molded pocket 110 attached to the pocket frame 60, the pocket frame and molded pocket can be placed in a lacrosse head mold. The lacrosse head 20, and in particular a lacrosse head frame including the various components such as the ball stop 23, sidewalls 24, 26 and scoop 28 can be molded over the pocket frame 60 and/or the molded pocket support rails to connect the pocket frame 60 and/or molded pocket 110 to the head 20 and its frame.
After the former molding operation is completed, the molded head, pocket frame, and molded pocket form an integral and monolithic structure which are all permanently attached to one another and cannot be separated from one another without destroying the one or more of the components. Of course, if desired, the head, pocket frame and/or molded pocket can be constructed with fastening features that allow these components to be nondestructively detached or disassociated from one another.
A second alternative embodiment of the lacrosse pocket is illustrated in
The pocket frame 160, and optionally the support rails of the molded pocket extending within the pocket frame, can define a plurality of pocket frame connector holes 169. These pocket frame connector holes can be defined in the ball stop member 167, the sidewall members 165 and 166 as well as the scoop member 168, which optionally can be continuous with one another, having no breaks or voids in any part thereof. Although not shown, these pocket frame connector holes can extend through any portion of support rails that are included in the pocket frame. Of course if desired, the holes 169 can be above or outside the support rails of the molded pocket 210. The connector holes 169 can be defined entirely around the molded pocket within the pocket frame 160.
As shown in
Although shown as being adjoined at a corner, the outwardly extending surface 169B and downwardly extending surface 169C of the stringing ridge 169A can transition at a rounded or arced corner. Alternatively, these surfaces 169B and 169C can form a part of a continuously curved surface, or a multi-faceted, multi-angled structure, or any other structure which generally provides structural registration of the pocket frame 160 within the stringing ridge 169A.
As further shown in
Optionally, although shown as being defined on the interior surface 22A of the head, the stringing ridge 169A alternatively can be defined on the exterior surface 26E of the rail 26. In this case, the pocket frame 160 can be displaced outwardly, rather than inwardly, of the rail 26 or other head structure.
Modifications to the attachment of the pocket frame and molded pocket to the ball stop, sidewalls and/or scoop shown in
Another example of the connection of the pocket frame and molded pocket to the ball stop, sidewalls and/or scoop, is illustrated in
The extension 216A can include a head or flange portion 216B extends into and optionally fills or occupies the recess 26F. The head located and registered in this recess can offer additional support and mechanical connection between the molded pocket 210 and the sidewall 26, or other component to which the molded pocket is joined. The outer surface 216E of the flange 216B can be configured to be flush with the exterior surface 26E of the rail 26A or other exterior surface of the head. If desired, however, it can extend outwardly and provide an ornamental or tactile effect over the exterior surface 26E. Optionally, although not shown, a pocket frame can include a similar extension and flange to connect the pocket frame to the head.
Further optionally, although shown with the molded pocket and/or pocket frame facing the interior 22 of the head, the pocket frame 260 and/or support rail 216 can alternatively be formed along or positioned near the exterior surface 26E of the sidewall 26 for other component to which these items are connected. In these constructions, the extensions extend inwardly through the net holes 29 and can include a similar head, flange or other enlarged portion to mechanically secure the pocket frame and/or molded pocket to the lacrosse head.
Yet another example of the connection of the pocket frame and molded pocket to the ball stop, sidewalls and/or scoop, is illustrated in
Although shown as being oval shaped, the extensions 368 can be of any geometric configuration, and can generally correspond to the shape of the net holes 29 defined by the sidewall, scoop, ball stop or other component of the head to which it is attached. To connect the pocket frame 360 and/or molded pocket 310 to the sidewall 26, the extensions 368 are placed through the net holes 29 so that the extension holes 369 are located beyond the exterior surface 26e of the sidewall 26. A lace or string 29S can be strung through the holes 369 in the extensions 368 that project past the exterior 26E of the sidewall 26. Optionally, the pocket frame could be reconfigured so that the extensions face inwardly, in which case the string 29S would be located on the interior of the lacrosse head when strung through the holes 369. Further optionally, although shown with the extensions 368 extending from the pocket frame, the molded pocket 310 can include a support rail as described in any of the embodiments herein. This support rail can include similar extensions, with the pocket frame absent from the construction.
A third alternative embodiment of the lacrosse pocket is illustrated in
The pocket 410, however, can differ from or be the same as the molded pocket described in connection with the other embodiments above. For example, the pocket 410 can be constructed from a conventional mesh material or other synthetic material. The mesh or synthetic material can be overmolded around its perimeter 415 by the pocket frame 460. In this construction the mesh or synthetic material is embedded in or encapsulated in the material making up the pocket frame. Thus, the material of the mesh or synthetic material can have embedded within its outer surfaces, and to some extent, within its structure, the polymeric material from which the pocket frame 460 is molded. This can provide a connection between the mesh or other synthetic material and the molded pocket 460.
The mesh or other material can be stretched or pre-tensioned laterally in opposite directions that are aligned with the lateral axis 101 at any number of infinite locations along the longitudinal axis 102. The mesh or other material also or alternatively can be stretched or pre-tensioned longitudinally in opposite directions aligned with the longitudinal axis 102 at any of infinite locations along the lateral axis 101. In its pre-tensioned state, whether laterally stretched, longitudinally stretched, or both, the pocket 410 can be molded to the pocket frame, and in so doing, can retain a generally taut and preconfigured shape and contour corresponding to the amount of residual tension left in the mesh or material after the molding.
Further, the mesh or other material can be preformed or shaped with a bulbous or contoured ball receiving area 419 of a mold. This ball receiving area can be shaped to hold a lacrosse ball placed in the pocket 410. Optionally, the pre-tensioning can enable the mesh to be held to form the bulbous formation 419 or other structures within the mesh or synthetic material of the pocket 410.
A method for making the third alternative embodiment of the pocket including the pocket frame 460 and the pocket 410 constructed from mesh, other material, or even the molded strings mentioned in the embodiments herein will now be described with reference to
The second mold part 402 can be configured to complete the mold cavity 404. The second mold part 402 can also include a plurality of locator elements, such as pins 405, that are disposed around at least a portion of a perimeter of the pocket frame mold cavity 404. These pins can be located directly on the cavity, can be located interior of it, or located exterior of it. The locator pins can be configured to extend outwardly and from the second mold part 402 so that when a mesh pocket or other synthetic pocket material is stretched over them, the locator pins register within holes 431 defined by the pocket 410 as described below.
The second mold part 402 also can define a projection portion 407 that projects outwardly away from the mold. This projection portion can be configured to correspond to a desired contour 419 for retaining a lacrosse ball within the completed pocket after it is molded to the pocket frame.
Generally, the first and second mold parts are used to mold a pocket frame to a mesh or synthetic or other pocket. With reference to
As shown in
Optionally, in some cases the mold can be modified to eliminate the locator pins yet still hold the mesh or other pocket material 410 in a pre-tensioned mode. For example, the mold can include clamps that clamp the edges 410E of the mesh or material and apply the forces +F1 and −F1 throughout the pocket frame molding operation. In this construction, the mold locator pins can be absent yet the mesh is still maintained in a pre-tensioned state before, during and after molding material to form the pocket frame.
Returning to
After the frame 460 has cured, as shown in
Optionally, the above method can likewise be used to mold a fabric, mesh, other synthetic material, or a molded pocket including molded strings as described herein directly to a lower portion of a conventional lacrosse head. In such a method, the pocket frame can be replaced with the lower rails, lower ball stop and/or lower portion of the scoop of the lacrosse head and the same steps followed.
Further optionally, the above method can be modified slightly so that the mesh or material of the pocket is pre-tensioned less, or not at all, and still molded to the pocket frame. For example, the mesh or material can be pre-tensioned a very small amount or simply loosely draped across the mold cavity. The pocket frame can be molded over the mesh or material. The pocket frame, however, can be sized slightly smaller than the head to which it will be attached. The pocket frame itself can be constructed from a slightly stretchable and/or elastic polymeric or other material. When the pocket frame is joined with the head, the frame is put under a tension and or stretched laterally, longitudinally, or otherwise, and in turn places the mesh or material of the pocket in a tensioned mode. To do so, the pocket frame or head, or tools to join the head and frame can include tapers or wedged portions to expand the perimeter or dimensions of the frame.
A method of manufacturing a molded pocket of the current embodiment described above will now be described with reference to
Injection molded material is injected through a network of runners 86 into the base molded pocket cavity 74 defined by the first pocket cavity portion 75A and the second and third pocket cavity portions 85A and 85B. An already formed lacrosse head 20 can be held in place relative to the base 73 via a retainer element 71. The lacrosse head 20 can include net holes or other apertures or grooves defined in its lowermost region, in communication with the molded pocket cavity 74. When the material is injected, it fills the cavity as well as engages the lacrosse head to affix the molded pocket to the lacrosse head.
Turning now with more particularity to
The retainer portion 76 can be the same size or slightly larger than the interior surfaces of the molded pocket around an inner perimeter 15 of the lacrosse head 20. This can ensure a friction or tight fit to promote tight tolerances when the pocket 10 is molded to the head 20. Optionally, where the molded pocket 10 is to be joined or molded to a pocket frame, such as those in the embodiments above, the retainer portion 76 can be sized and configured to engage the interior of the pocket frame in a similar manner. Generally, the retainer portion can be reduced in height due to the fact that the pocket frame is typically shorter in height than the sidewalls and/or base of a lacrosse head. With the pocket frame appropriately placed, the molded pocket can be injection molded using the techniques and methods described herein.
Returning to
The molded pocket cavity 74 can be collectively formed by the first pocket cavity portion 75A of the base 73 and/or lifter 71, the second pocket cavity portion 85A, and the third pocket cavity portion 85B which are respectively defined by the mold slide 81 and the mold slide 82. The molded pocket cavity 74 can collectively define all of the surfaces mirroring the finished molded pocket. The molded pocket cavity 74 also can be in direct fluid communication with the lacrosse head 20 and its components to promote attachment of the molded pocket to a lacrosse head, or optionally to a molded pocket frame as desired. The molded pocket cavity 74 also is in direct fluid communication with multiple runners 86 defined by the mold, for example the base mold 73 and/or the mold slides 81 and 82. These runners can deliver a supply of molding material, for example polymeric materials, such as those described above, to form the molded pocket 10 in the molded pocket cavity 74. A variety of different configurations of the runners can be used depending on the particular application.
As shown in
With reference to
The mold slides 81 and 82, and/or the base 73, can include an internal head relief portions 87A and 87B. These portions are configured to allow clearance between the slides 81, 82 when they are folded or pivoted closed, and the head 20 placed on the retainer portion 76. The head 20 can fit within the respective reliefs 87A and 87B defined by the slides 81 and 82, so that the slides 81 and 82 do not engage or contact the head.
Further, each of the slides can be configured to include an inner engagement surfaces 86A and 86B. When the slides 81, 82 are closed in the position shown in
The slides 81 and 82 can be strategically positioned and moveable in a specific path or paths to ensure that they release in a consistent, non-damaging manner from the complex molded features of the molded pocket, and its intricate and multifaceted surfaces is consistent. As described above, the individual molded strings, molded combined strings and shooters of the molded pocket can be of various complicated shapes and complex geometric configurations. For example, as shown in
To achieve the pivoting action of the slides, the axes 81A and 82A of the respective slides 81 and 82 can be positioned to facilitate precise and accurate movement in the directions R4 when the slides are folded open. The axes 81A and 82A of the respective doors 81 and 82 can be positioned “above” the lowermost portion 20L of the lacrosse head 20 when the head is positioned horizontally, with the lower rail vertically below the upper rail. The perspective in
The axes 81A and 82A can be specifically positioned to ensure the clean release of the second pocket cavity portion 85a and the third cavity pocket portion 85b from the molded pocket after it is formed. For example, as shown in
As shown in
Generally, the pivot axes are located laterally outward from the lacrosse head, and vertically above the lowermost portion 20L of the lacrosse head and/or molded pocket cavity 74, or generally above and laterally away from the sidewalls of the lacrosse head, or the molded pocket cavity 74, as shown in
Although not shown, the first and second slides 81 and 82 can be connected to pneumatic or hydraulic element which can move those first and second slides 81 and 82 about the pivot axes 81A and 82A. Further, if desired the slides 81 and 82 can be separated up into multiple individual side-by-side slides which are pivotable about additional or fewer axes than the two illustrated. For example, the mold could be configured with a first portion of a mold cavity defined by a base mold and a second portion of the mold cavity defined by a single slide. The single slide could be pivotable about an axis similar to the axes above. To open the mold, the slide could pivot generally like a door about the single axis, opening away from the base mold to thereby separate the second mold cavity portion from the first mold cavity portion, freeing the molded article inside the collective mold cavity.
The axes 81A and 82A of the respective mold slides 81 and 82 are generally parallel to one another and disposed on diametrically opposed on opposing sides of the axis of symmetry 79 of the lacrosse head. The axis or line of symmetry can be aligned with the longitudinal axis 102 of the lacrosse head. If desired, the slides can optionally be reconfigured so that they are not parallel and are offset as some angle relative to one another, and relative to the axis of symmetry 79.
As shown in
With further reference to
Operation of the mold, and the method for forming a molded pocket will now be described with reference to
Further optionally, the mold can include a second slide across a line of symmetry of the mold. The second slide also can pivot about a second pivot axis, which is parallel to but offset laterally relative to the line of symmetry an the opposite side of the head. The second slide can include a third cavity portion which, when brought against the first cavity portion is in communication with that first cavity portion and the second cavity portion to form the completed molded pocket mold cavity in which the molded pocket can be formed.
Even further optionally, a clamp plate can be pressed adjacent the first slide and optional second slide to secure and/or capture the slides so that they do not separate from one another or distort the finished mold cavity during the molding of the molded pocket. Material can be injection molded into the molded pocket mold cavity.
As the molded pocket is molded, it joins with the lacrosse head and/or pocket frame mechanically and/or via a bonding action between the material of the injection molded pocket and the head or pocket frame. After the molded pocket is formed, the first and optional second slides can be pivoted or folded open about the pivot axes. Due to the pivoting action, optionally away from the line of symmetry, the second mold cavity portion and optional third cavity mold portion cleanly and consistently break or separate away from the molded pocket so that it remains intact and does not tear. Optionally, the internal surfaces of the second mold cavity portion and optional third cavity mold portion move in an arcuate or curved pathway away from the molded features and surfaces of the molded pocket as the slides are pivoted open.
The lacrosse head and/or pocket frame having the molded pocket joined with it can be removed from the mold. Any sprues or flashing formed during the molding process can be removed from the molded pocket.
More particularly, as shown in
Turning now to
As shown in
Generally, during the closing action, the second molded pocket mold cavity portion 85A and third molded pocket mold cavity portion 85B of the respective slides move along arcuate pathways toward the first molded pocket mold cavity portion 75A. This movement along those arcuate pathways can be due to the pivoting action about the respective axes. Optionally, the each of the various surfaces and points of the second molded pocket mold cavity portion 85A and third molded pocket mold cavity portion 85B can move along their own single arcuate pathway, generally rotating toward one another as the slides are closed to the closed mode. This action sometimes can be referred to as a barn door closing action.
As shown in
After the molded pocket is sufficiently molded and cured within the molded pocket cavity, the mold can be opened. This is illustrated in
Generally, during the opening action, the second molded pocket mold cavity portion 85A and third molded pocket mold cavity portion 85B of the respective slides move along arcuate pathways away from the molded pocket and the first molded pocket mold cavity portion 75A. This movement along the arcuate pathways can be due to the pivoting action about the respective axes. Optionally, the each of the various surfaces and points of the second molded pocket mold cavity portion 85A and third molded pocket mold cavity portion 85B can move along their own single arcuate pathway as the slides are opened, and generally rotate away from one another.
Any remaining sprues can be removed at this point from the molded pocket and/or mold. The slides 81 and 82 can continue to open as shown in
With all of the embodiments described above, a durable and easy-to-install pocket and related method are provided.
