Abstract

A protective glove can include a unitary dorsal panel formed from an inner scrim material and a plurality of protective elements molded directly to an exterior surface of the inner scrim. Two or more protective elements can be formed as an array of discrete islands each separated by substantially zero-elevation interstitial spaces. The unitary dorsal panel can be sewn or otherwise attached circumferentially to the palmer sections of the glove. This array of protective elements can provide increased protection to the user's fingers, hands, wrists, and lower forearms while maintaining flexibility and tactile feel on both palmar and dorsal sides of the glove, increasing flexibility where needed without compromising protection.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is a continuation of application Ser. No. 14/602,915 filed Jan. 22, 2015, which in turn derives priority from U.S. provisional patent application No. 61/930,311 filed Jan. 22, 2014.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to padding for lacrosse gloves and other athletic apparel and accessories, and more particularly, to a protective sports glove and stitchless dorsal padding for the same that provides improved flexibility, increased protection, finer tactile feel and economy of manufacture.

2. Description of the Background

Protective sports gloves are commonly used and, indeed, are required to be used in many organized sports such as lacrosse, hockey, and other contact sports. Such gloves protect the wearer from impact of lacrosse sticks, hockey sticks, balls, pucks, skates, and other players.
Protective sports gloves include padding to protect the player's fingers, hands, wrists and lower forearms. Despite their protective function, such gloves must balance other design factors such as weight, feel and flexibility. For example, the handling of a lacrosse stick requires a player to hold and control a lacrosse stick handle in specific ways, with many different combinations of hand placement over the length of the handle. A lacrosse player constantly moves his hands along the handle in multiple positions.
In executing game skills, lacrosse players must be able to grip and control the lacrosse stick handle, i.e., “stick handling.” Effective stick handling requires a player to constantly reposition his hands along the handle to control the head of the lacrosse stick. For effective stick handling, a lacrosse player needs to maintain utmost flexibility of the hand, a sure grip, and a precise tactile feel for the stick. However, the hand also needs protection and so players typically wear padded gloves to protect their hands and wrists. These gloves usually include foam padding or other protective padding covering the back of a wearer's hand, fingers, and thumb (collectively, “dorsal padding”).
Some conventional sports gloves have pad segments (e.g., made of foam) that are covered with leather or synthetic leather and, in the breaks between the segments, are stitched to one another and to a liner material (also known as the scrim). The scrim may be any woven or knit fabric. In these conventional gloves individual foam pads are typically sandwiched between two fabric layers, and the layers are sewn together and to the scrim, between breaks in adjacent pads. However, this conventional construct is relatively thick and fairly rigid in design and compromises flexibility and tactile feel for protection. When such a protective athletic glove undergoes deformation due to normal use by a wearer, adjacent pads come into contact with each other and this arrests/resists further motion. In addition, the inflexibility of the fabric layers and liner resist stretching and further arrests/resists motion. In straining against these forces to maintain a grip on the lacrosse stick, a player tends to lose their tactile feel for the stick, and consequently their stick handling capability. Flexibility can be increased by larger spacing between adjacent pads, but larger spacing compromises protection of the player.
Moreover, conventional stitched dorsal padding unduly complicates the overall glove construction. The individual pads for the dorsal panel are typically sewn together, and the overlapping sewn-layers restrict flexibility. This lack of flexibility makes it very difficult to invert the glove when stitching on the palmar section (the glove is inverted when stitched interior seams are desired). The additional stitching and difficulty in manipulating the glove during manufacturing adds significant time and expense.
What is needed is a protective sports glove and “unitary” dorsal panel for the same that allow for a tightly-packed pad array, yet still provides improved flexibility, increased protection, finer tactile feel, and greater economy of manufacture.

SUMMARY OF THE INVENTION

Embodiments of this disclosure can include a protective sports glove that includes a unitary dorsal panel having a waffle-pattern array of foam protective pads formed as individual islands raised from a substantially zero-elevation surface. Two or more of the foam protective pads can be separated from each other by an interstitial channel having a width within a range of 1-4 mm. The glove can further include a palmar section fused, welded, stitched, molded or otherwise connected to the dorsal section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The unitary padding array of embodiments of the present invention can provide advantages to address the deficiencies discussed in the background section above and may also be used for helmet liners, head gear (e.g., wrestling), other specialty gloves (e.g., baseball, boxing, biking, golf, lacrosse, equestrian, hockey, etc.), shoulder pads, knee pads, elbow pads, bicycle seats, joint supports (e.g., elbow, wrist, knee, hip, neck, shoulder and ankle), padded garments (e.g., biker shorts, etc.), joint braces (e.g., elbow, wrist, knee, hip, neck, shoulder and ankle), and other general padding and supports.
In one aspect of an embodiment of this disclosure, a protective glove can include a hand receiving portion that includes a plurality of finger portions, a thumb portion, a metacarpal portion and a wrist portion. The hand receiving portion can include a dorsal side and a palmar side. The dorsal side of the hand receiving portion can include a unitary dorsal panel formed from an inner scrim material and a plurality of protective elements molded directly to an exterior surface of the inner scrim. For purposes of this disclosure “unitary” is specifically defined to mean formed as a one-shot molded synthetic panel, or formed by a plurality of such panels integrally joined together by fusion of their synthetic material or by fusion of the protective pads to the underlying scrim material (e.g., RF welding, heat welding, etc.), but not stitched.
The plurality of protective elements can be formed in an array of discrete islands, each separated by substantially zero-elevation interstitial spaces. The array of protective elements can be formed in any of a variety of patterns suitable for the purposes of this disclosure. For example. The array may be arranged in a waffle-pattern. This array can provide increased protection to the user's fingers, hands, wrists, and lower forearms while maintaining utmost flexibility and tactile feel on both palmar and dorsal sides of the glove, increasing flexibility where needed without compromising protection. Flexibility is desired by the wearer so as to impart freedom of movement to the fingers, hand, wrists and lower forearms, which is needed to maintain an accurate tactile feel for the lacrosse, hockey or other sports stick during a match, while protection is required to reduce injury.
The unitary dorsal panel can be fused, welded, stitched, molded or otherwise connected to the palmer sections of the glove. For example, the unitary dorsal panel can be sewn circumferentially to the palmer sections of the glove, with or without gussets and/or gusset stitching (for example, gussets are typically sewn between the dorsal and palmar sides of gloves running alongside the fingers). The cut pattern for the palmar section may vary. In some embodiments, the palmer section may include three discrete sections: a finger-receiving section; a palm section, and a thumb section.
In accordance with an embodiment this disclosure, when manufacturing the glove, the palmar section can be sewn end-to-end across the dorsal panel, with or without gussets, and the glove can be inverted. The finger-receiving section and thumb section can then be sewn on and the glove turned outside-in yielding internal seams (“inside stitching”). For this inside stitching the embodiments of this disclosure provide an additional advantage. The typical reversing out of gloves dictates a minimum gusset width, which results in a looser fit. Embodiments of this disclosure can facilitate a tighter standard for gusset width, which translates into a tighter fit. Of course, the finger-receiving section and thumb section may alternatively be sewn together exteriorly without inversion (“outside stitching”).
Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Lacrosse, hockey and other stick-wielding sports gloves need to be able to flex in multiple directions freely in order for players to grip their stick and engage in necessary wrist action while still maintaining an acceptable level of protection. However, as discussed above, conventional glove design limits the amount of flex that is available to a player when they are manipulating a lacrosse or hockey stick. Specifically, conventional protective sports gloves have limited flexion and extension as well as difficult radial and ulnar deviation, and poor dorsiflexion as well. Described herein is a protective sports glove and padding for the same that can maximize flexibility without compromising protection, thereby affording more accurate tactile feel for better stick-handling.
An embodiment of the present invention provides a protective sports glove that can include a unitary dorsal panel that includes a molded pattern-array of foam protective pads closely fitted to the hand, and a palmar section stitched to the dorsal section directly or via gussets and/or gusset stitching.
With reference to FIG. 1, a first embodiment of a protective athletic glove 2 is shown which generally can include a hand receiving portion 22 covering all five digits and the carpometacarpal joints of the hand and extending down at least to the wrist crease, or further to cover all or a portion of the wrist. A lower wrist/forearm portion 24 can extend down from the hand receiving portion 22 by a distance from one to three inches. Glove 2 inclusive of both hand receiving portion 22 and lower wrist/forearm portion 24 can have both a palmar side (obscured) and a dorsal side (shown). The junction of the hand receiving portion 22 and lower wrist/forearm portion 24 can be partially encircled by a cuff inclusive of a wrist cushion 25 that partially surrounds the dorsal side and an adjustable collar 26 that extends below the hand receiving portion 22 and which may be tightened across the palmar side by hook-and-loop pads. The hand receiving portion 22 can further include a first (little finger) receiving portion 31, second (ring finger) receiving portion 30, third (middle finger) receiving portion 29, fourth (index finger) receiving portion 28, and a fifth (thumb) receiving portion 27.
The back of the hand receiving portion 22 inclusive of finger and thumb receiving portions 27-31, as well as the entire dorsal side down to the lower wrist/forearm portion 24 can define a unitary dorsal panel 40 having an array of protective pads 54 formed as individual islands raised from a substantially zero-elevation surface 52. Protective pads 54 can be integrally-molded or fused to the substantially zero-elevation surface 52 such that interstitial channels of minimal substrate thickness are formed between the discrete pads 54. Unitary dorsal panel 40 may include a main section 23 defined by a portion of the unitary dorsal panel 40 that does not include first 31, second 30, third 29, fourth 28, and fifth 27 receiving portions. The main section 23 can be configured to correspond to the back of a wearer's hand. In the embodiment of FIG. 1 the zero-elevation surface 52 can include a thin pliable layer of any suitable scrim material. The scrim material may be any pliable textile or synthetic sheet material including natural or synthetic fabric, and may optionally be porous and/or stretchable. Suitable materials for the scrim material include polyester, cotton, and nylon. The scrim material of zero-elevation surface 52 may be woven from warp and weft threads which provide mesh openings or interstices between the threads. However, other scrim materials, such as, for example, perforated fabric, can also be used so long as the scrim material permits the pads 54 to bond or adhere with the scrim material.
The scrim material may or may not have a limited stretch characteristic to it. Toward this end scrim material may be cut from a knitted/woven stretchable fabric blank comprising a material formed from a combination of first yarn strand(s) made of synthetic fibers, and a second elastomeric stretchable yarn strand. The first yarn strands can be knitted/woven together with the elastomeric second strand to create a single blank of woven/knitted fabric. The knitted/woven blank can have a specific fiber content vis-à-vis the combination of the two strands of yarn used. The first yarn strands may be 100% polyester, which is the dominate fiber of the fabric blank. As an alternative to polyester, the first yarn strands may comprise nylon. The second elastomeric yarn strand may be comprised of any elastic textile fiber, however, it is preferred that this material be made of the elastomeric textile fiber known as spandex. Specifically, the knitted/scrim material may comprise a blend of polyester or poly-cotton yarn and spandex, wherein the spandex fiber content is constrained to within an acceptable range of from 3 to 15%, and most preferably is 6%. This may be achieved with a knit/weave ratio of synthetic yarn/spandex yarn of from 33:1 to 20:1, and identical deniers. One skilled in the art will understand that the variation between fabric blends may also be made possible by varying the ratio of yarns and the structure of the knit or weave pattern.
The array of integral pads 54 formed on the unitary dorsal panel can be raised relative to zero-elevation surface 52 and can be formed integrally thereto by a process of sonic Radio Frequency (“RF”) welding as described below in Example 1. Alternatively, the array of integral pads 54 may be formed on the unitary dorsal panel by a process of compression molding as described below in Example 2 or may be individually attached to the scrim material by adhesive. In either case the protective pads 54 comprise rubber and/or foam, most preferably open-cell or closed-cell foam rubber blocks fused or integrally-molded to the scrim material by molding, casting or other suitable fusion method. The pads 54 can form discrete islands separated from each other by interstitial channels 58 flush with zero-elevation surface 52.
FIG. 2 illustrates a second embodiment of a protective athletic glove 12 similar to FIG. 1 except that a unitary dorsal panel 140, again having a zero-elevation surface 152 and array of integral pads 154, can be formed by compression molding as described below in Example 2.
In both cases the array of integral pads 54, 154 can be formed on the unitary dorsal panel 40, 140 by molding/fusing/adhering them into the scrim fabric. The particular pattern of shock absorbing pads 54, 154 can be designed to provide increased protection to the dorsal side of the user's fingers and hands while maintaining as much flexibility within the glove and tactile feel as possible. For example, shock absorbing pads 54, 154 can be arranged in a waffle-pattern array. Flexibility is desired by the wearer so as to impart freedom of movement to the fingers, hand, wrists and lower forearms needed to properly participate in lacrosse, hockey or other sports matches while protection is required to reduce injury.
In the illustrated embodiment some of the shock absorbing protective pads 54, 154 can be shaped as blocks and most preferably a trapezoidal prism, while some proximate the wrist crease are shaped as crescents. The particular shapes of the pads 54, 154 may be altered to promote specific performance improvements. Other exemplary shapes and configurations of pads 54, 154 for specific performance improvements are described below with reference to FIG. 8:
i. Pads 54, 154 may be hollow concave blocks having open cavities in the underside for lighter weight (see FIG. 8(a));
ii. Hollow concave pads 54, 154 may be dual-durometer, e.g., the open cavities in the underside as per (i) above may be adapted for insertion of stiffer impact-resistant material for improved protection (see FIG. 8(b));
iii. Pads 54, 154 may be formed with angled top surfaces for improved deflection of impacts (see FIG. 8(c));
iv. Pads 54, 154 may be formed with shaped and/or sculpted surfaces to conform to a lacrosse stick handle (see FIG. 8(d));
v. Pads 54, 154 in the lower wrist/forearm portion 24 may be formed with angled surfaces for improved wrist flexibility (see FIG. 8(c)).
Of course, one skilled in the art should understand that pads 54, 154 may be formed in other shapes or with other surface features or inserts to achieve specific performance characteristics, and such other shapes, surface features or inserts are considered to be within the scope and spirit of the invention.
Comfort is also important and toward this end venting may be provided through the scrim material between the discrete pads 54. Specifically, said the scrim material may include one or more pass-through vents between the discrete pads 54 for improved air circulation.
FIG. 3 illustrates the pattern on the dorsal section of glove 2 for the embodiment of FIG. 1. Each of the finger receiving portions 28-31 and thumb receiving portion 27 can bear a plurality of shock absorbing pads formed as blocks. With reference to the little finger receiving portion 31, these pads 62 can be preferably aligned end-to-end and spaced very closely, within a range of from 1-4 mm and most preferably approximately 2 mm. The 2 mm interstitial breaks can provide flexibility between the cushions when a wearer's hand is flexed. The faces of opposing pads 62 can be inclined at an obtuse angle to allow a limited degree of counter-arching of the fingers, but eventually make contact to prevent over-arching. A variety of pads 64 can occupy the dorsal panel beneath the finger receiving portions 28-31 and these can also be welded or otherwise attached to the liner scrim beneath. Any suitable geometry of shock absorbing pads 64 may be provided to optimize both protection and flexibility.
All shock absorbing pads 62, 64 are generally made of a discrete block of any suitable protective material such as micro-cellular foam, preferably open cell, urethane foam (e.g., Poron™, PVC nitrile foam, or another suitable impact-absorbing closed cell foam material). The interstitial channels 58 can be of substantially minimal substrate thickness and substantially minimal spacing between the discrete pads 54. In the embodiment of FIGS. 1 and 3 the zero-elevation surface 52 comprises a thin single layer of suitable scrim material, and the scrim can effectively form flexible hinges at the interstitial channels 58 between the discrete pads 54. This is best seen in the inset of FIG. 3. Specifically, the thickness of the scrim t at the interstitial channels 58 can be preferably on the order of 0.1-4.0 mm and is most preferably approximately 0.4 mm. If desired, a very thin layer of Ethylene-vinyl acetate (“EVA”) foam 51 may be added to the back (lower) side of the scrim material 52, or other suitable adhesion promoter, to improve adhesion of the discrete pads 54 (see FIG. 3 inset) on the front (upper) side of scrim material 52. Discrete pads 54 can be preferably molded EVA foam blocks ranging from 9 mm to 13 mm in thickness. Thus, as an example, the layers in the illustrated embodiment can comprise (moving from hand to outside of glove):
i. Layer 1—optional thin layer of EVA adhered to scrim material 52 (1 mm preferred)
ii. Layer 2—scrim material 52 (0.1-4.0 mm thickness, 0.4 mm preferred);
iii. Layer 3—Discrete EVA pads 54 ranging from 9 mm to 13 mm thickness.
The interstitial channel spacing s between the discrete pads 54 can be preferably on the order of 0.5-5.0 mm and is most preferably approximately 1 mm. If desired, optional hard shell tiles 66 formed of polyethylene, Nylon or other suitable impact-resistant material may be inset/adhered or otherwise formed in the top surface of each discrete pad 54 to add impact resistance.
As seen in FIGS. 1-2 the lower wrist/forearm portion 24 can be defined by a cuff attached below the hand receiving portion 22, the cuff can include a wrist cushion 25 that partially surrounds the dorsal side and an adjustable collar 26 that extends below the wrist cushion 25 and which may be tightened across the palmar side by hook-and-loop pads, or alternatively by traditional string lacing for wrist cuff closure.
FIG. 4 illustrates the pattern on the dorsal section of glove 12 for the embodiment of FIG. 2. As above each of the finger receiving portions 28-31 and thumb receiving portion 27 can bear a plurality of shock absorbing protective pads 162, that are shaped as blocks and may be formed as blocks and may be formed as trapezoidal prism. With reference to the little finger receiving portion 31, these pads 162 can be preferably aligned end-to-end and can be spaced closely, within a range of from 1-4 mm and most preferably approximately 1 mm. The 1 mm interstitial breaks can provide flexibility between the cushions when a wearer's hand is flexed. The faces of opposing pads 162 can be preferably inclined at an obtuse angle to allow a limited degree of counter-arching of the fingers, but eventually make contact to prevent over-arching. A variety of pads 164 can occupy the dorsal panel beneath the finger receiving portions 28-31 and these can also be integrally molded to the liner scrim 152 beneath. All pads 162, 164 can be preferably compression-molded or otherwise fused to the zero-elevation surface of scrim 152 using any suitable protective material such as micro-cellular foam such as, for example, open cell, urethane foam (e.g., Poron™, PVC nitrile foam, or another suitable impact-absorbing closed cell foam material). Compression-molding as per the embodiment of FIGS. 2 and 4 can impregnate the scrim fabric 152 and add very slightly to the dimensions of interstitial channels 158, but channels 158 can nevertheless be of substantially minimal substrate thickness and spacing between the discrete pads 154. In the embodiment of FIGS. 2 and 4 the zero-elevation surface 152 can include a thin unstitched rubber and/or foam-impregnated layer of scrim material that again effectively forms flexible hinges at the interstitial channels 158 between the pads 154. Specifically, the thickness of the scrim t at the interstitial channels 158 can be preferably on the order of 0.1-1.0 mm, and can most preferably be approximately 0.4 mm. The channel spacing s between the discrete pads 154 can be preferably on the order of 0.5-5.0 mm, and can be most preferably approximately 1 mm.
In both above-described embodiments, the pad array can be molded onto a square blank of scrim material 52, 152 and the blank may be cut (die, laser, rotary-blade, water-jet, etc.) using an outline cut that results in a substantially contiguous border flange 166 framing the dorsal panel 40, 140, resulting in the dorsal panels as shown in FIGS. 2 and 4. Preferably, the border flange 166 surrounding dorsal panel can be within a range of from 2-8 mm across, and most preferably a 5-6 mm margin. Palmar sections, such as palmar section 192 can be fused, welded, stitched, molded or otherwise connected to the border flange 166 around all four of the finger receiving portions 27, 28, 29 and thumb 30. The border flange 166 may be a uniform flat strip but is more preferably non-uniform for maximum flexibility. For example, for maximum flexibility the border flange 166 along at least a portion of the five finger-receiving sections 27, 28, 29, 30 and 31 can include a series of V-notch slits 168. The border flange 166 may also have a non-flat cross section configured to avoid interference between the border flange 166 of adjacent finger-receiving sections 27, 28, 29, 30 and 31. For example, the border flange 166 may be sloped, beveled or tapered outwardly away (see FIG. 6 bottom) from the finger-receiving sections 27, 28, 29, 30, and relative to the zero-elevation surface. Due to the inverted assembly described below, the glove 2 can have inverted seams in normal use, meaning the border flange 166 can be tucked under the palmar section 192 and the latter is stitched thereto around at least a portion of all four of the finger receiving portions 27, 28, 29 and thumb 30.
As seen in FIG. 6, the scrim material layer 52, 152 may again be any pliable textile or synthetic sheet material including natural or synthetic fabric and may optionally be woven from warp and weft threads 31 and 32 which provide mesh openings or interstices 33 between the threads 31 and 32. Optionally, perforated or needle punched fabric can also be used so that the fabric is provided with openings which permit the rubber and/or foam to interlock with the fabric. Suitable materials for the fabric can include polyester, cotton, and nylon.
As detailed below in Example 1 sonic welding can cause the rubber/foam to fuse to the scrim material, and where the scrim material is perforated or woven it can flow into the mesh openings of the textile scrim fabric 52, 152 and mechanically interlocks with the fabric. The fabric can reinforce the rubber/foam, strengthen the rubber/foam especially in the interstitial areas, and reduce the possibility that the dorsal shell will tear.

EXAMPLE 1

Sonic-Welded Dorsal Panel

FIG. 5 is a process drawing illustrating an exemplary process for making a dorsal section of glove 2 for the embodiment of FIG. 1. Initially, at Step 1 the entire array of protective pads 52 can be produced by either cold or heat compression in a tool, for example, cast-in-place by pour-casting into a two-part mold. At step 2, the protective pads 52 can be die-cut either post compression or during compression to attain their finished form. As seen at Step 3 the protective elements can be placed back into the tool/mold and pressed onto a substrate using an adhesive film laid overtop pads 52 to keep them registered. As seen at Step 4, the combined film, substrate and protective pads 52 can be placed into a flatbed high frequency welding station 100 as seen at B. To perform HF welding, two opposing die platens 150, 160 can act as capacitor plates. An oscillating electrical current can be applied to the mold 72/fabric blank 62 combination between the die platens 150, 160. The oscillating electrical field in conjunction with capacitive platens 150, 160 can convert the oscillating electrical current into an oscillating electric field that is applied to the mold 72/fabric blank 62 combination. The die platens 150, 160 may comprise brass, steel, aluminum/magnesium, or other similar materials. To perform the weld, the die platens 150, 160 can be compressed together and the ultrasonic field and combined pressure can cause localized melting of the protective pads 52 only at the interface of the scrim fabric and the protective pads 52, resulting in fusing of the pads 52 to the scrim fabric. As shown at Step 5, during the heat compressing process, the foam of the protective pads 52 can expand and, with a porous substrate, can slightly permeate the substrate, flowing into the mesh openings of the textile scrim fabric 52, 152 and mechanically interlocking with the fabric, creating a unitary bond between the protective elements 52 and substrate. If the substrate is not porous substrate, during the heat compressing process, the foam of the protective elements can fuse/adhere to the scrim substrate. The net result can be a dorsal panel as illustrated in FIG. 3. At Step 6 the dorsal panel can be die cut to the desired shape.
In yet another embodiment, a unitary dorsal section 40 of glove 2 for the embodiment of FIG. 1 can be created using a plurality of independent scrim sections by fusing protective pads 62 via the sonic welding process of FIG. 5 across the multiple sections of scrim material 52 to bridge them, effectively fusing them together.

EXAMPLE 2

Textile Reinforced Compression Molded Foam Rubber Dorsal Panel

FIG. 6 is a process drawing illustrating an exemplary process for making a dorsal section of glove 2 for the embodiment of FIG. 2. Initially, at Step 1 a mold fabricated with protective element cavities can be pre-heated. At Step 2 an optional thermoplastic polyurethane (TPU) film can be laid on the bottom portion of the mold. One skilled in the art should understand that the TPU film may be omitted to reduce manufacturing cost. At Step 3 the mold can be closed and dorsal section of glove 2 can be vacuum formed by releasing the air out of the bottom portion of the tool/mold so that the TPU film lines the bottom of the tool. At step 4 polyurethane can be poured into the tool/mold using multiple gates, to allow the polyurethane to completely fill the tool cavities. At Step 5 the tool can be put on a conveyer through an oven. The polyurethane can thermally expand to fill the tool/mold cavities. At Step 6 the tool can be opened, and at Step 7 a substrate can be laid or pinned into the tool. The substrate may be a rubber and/or foam sheet. At Step 8 the tool can be closed and the rubber/foam 66 softens and/or becomes fluid in the mold and as a result of compression flows out of the interstitial channels and into the pad sections, also flowing into the pores of the scrim material 62 and around the threads as illustrated in FIG. 6C. The rubber/foam 66 thereby can form a mechanical interlock or bond with the scrim material 62. When the rubber/foam cools, the fabric can be integrated with the rubber/foam.
Moreover, the heat and pressure of molding displaces the rubber/foam into the mold cavities and can define the substantially zero-elevation interstitial surfaces surrounding the array of raised pads 152, each pad forming a raised island on the substantially zero-elevation surface 52. The scrim material 62 strengthens and reinforces the rubber/foam 66. If desired, the foam rubber 66/scrim 62 combination can be molded into a particular shape. For example, the dorsal panel can be provided with a preformed arch to conform to the back of the hand.
The textile reinforced zero-elevation interstitial hinges can increase flexibility without compromising protection, thereby affording more accurate tactile feel for better stick handling. The unitary (stitchless) dorsal panels 40, 140 can also substantially reduce manufacturing time and expense. Either embodiment of the unitary dorsal panel 40, 140 may be sewn or otherwise attached circumferentially to the palmer sections of the glove. FIG. 7 illustrates an exemplary cut pattern for the palmar section which generally comprises three discrete sections: a finger-receiving section 190; a palmar section 192, and a thumb section 193. The palmar section 192 can be cut from a blank to define the palmar side of four of the finger receiving portions 28, 29 but not thumb 30. On both sides of the finger-receiving section 190 a protruding margin may be formed 193A, 193B. One skilled in the art should understand that margins 193A, 193B may be convenient for stitching but are non-essential and may be eliminated as a matter of design choice. The margin 193A can protrude outward beginning at the distal phalangeal joint of the index finger-receiving portion 28 and can increasingly protrude outward ending at the metacarpophalangeal joint. The margin 193B can protrude outward beginning at the distal phalangeal joint of the little finger-receiving portion 32 and can increasingly protrude outward ending at the base of the little finger metacarpals bone.
For assembly, the finger-receiving section 190 can be frequently inverted and stitched to the inverted dorsal panel 40, 140 by seams, for example, through facing margins 193A, 193B and the margins surrounding dorsal panel 40, 140. The X/Y interface shown in FIG. 7 is not sewn. The palm section 192 is sewn to the inverted finger-receiving section 190 at the X/Y interface. Thumb section 193 is rolled and stitched into a receptacle, and is inverted. The combined finger-receiving section 190 and dorsal section 40, 140, still inverted, is sewn to the still-inverted thumb section 193. The entire assembly is re-inverted to produce the final glove 2, 12 with interior seams.
The palmar section 192 is cut from a blank to define the palmar side of four of the finger receiving portions 28, 29 but not thumb 30. On both sides of the finger-receiving section 190 a protruding margin may be formed 193A, 193B. One skilled in the art should understand that margins 193A, 193B may be convenient for stitching but are non-essential and may be eliminated as a matter of design choice. The margin 193A protrudes outward beginning at the distal phalangeal joint of the index finger-receiving portion 28 and increasingly protrudes outward ending at the metacarpophalangeal joint. The margin 193B protrudes outward beginning at the distal phalangeal joint of the little finger-receiving portion 32 and increasingly protrudes outward ending at the base of the little finger metacarpals bone.
Since the dorsal panel 40, 140 has highly-flexible interstitial hinges (rather than overlying layers where pads are sewn together, where overlapping sewn-layers restrict flexibility), the combined finger-receiving section 190 and dorsal section 40, 140 are much easier to invert manually. The additional flexibility makes it possible to quickly invert the glove 2, 12 when stitching on the palmar section and saves significant time and expense.
It should now be apparent that the above-described protective sports glove 2, 12 with unitary stitchless dorsal sections 40, 140, allow a user to flex the hand in all directions freely, to grip a lacrosse, hockey or other type of sports stick, and to maintain accurate tactile feel at every necessary wrist inclination, all while maintaining a suitable level of protection. The glove 2 allows freer flexion and extension, as well as radial and ulnar deviation, and dorsiflexion.
Variations and modifications of the embodiments described herein are considered within the scope and spirit of the invention. For example, the unitary dorsal padding array of the present invention may be inserted in compressed or uncompressed form within a pocket formed in the scrim material on the dorsal side of the glove 2. Such pocket would allow for easier construction, reducing labor costs, and may be better suited for an intermediate level of play. The pocket circumferential edges may be sewn to the palm and fingers with one side of the pocket left open to insert and receive the compressed dorsal panel.
The unitary dorsal padding array of the present invention provides these advantages and may also be used for helmet liners, head gear (e.g., wrestling), other specialty gloves (e.g., baseball, boxing, biking, golf, lacrosse, equestrian, hockey, etc.), shoulder pads, knee pads, elbow pads, bicycle seats, joint supports (e.g., elbow, wrist, knee, hip, neck, shoulder and ankle), padded garments (e.g., biker shorts, etc.), joint braces (e.g., elbow, wrist, knee, hip, neck, shoulder and ankle), and other general padding and supports.
