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
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Other objects, features, and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments and certain modifications thereof when taken together with the accompanying drawings in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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).
[0026] 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.
[0027] 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.
[0028] With reference to
[0029] 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
[0030] 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--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.
[0031] 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.
[0032]
[0033] 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.
[0034] 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
[0035] i. Pads 54, 154 may be hollow concave blocks having open cavities in the underside for lighter weight (see
[0036] 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
[0037] iii. Pads 54, 154 may be formed with angled top surfaces for improved deflection of impacts (see
[0038] iv. Pads 54, 154 may be formed with shaped and/or sculpted surfaces to conform to a lacrosse stick handle (see
[0039] v. Pads 54, 154 in the lower wrist/forearm portion 24 may be formed with angled surfaces for improved wrist flexibility (see
[0040] 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.
[0041] 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.
[0042]
[0043] 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
[0044] i. Layer 1optional thin layer of EVA adhered to scrim material 52 (1 mm preferred)
[0045] ii. Layer 2scrim material 52 (0.1-4.0 mm thickness, 0.4 mm preferred);
[0046] iii. Layer 3Discrete EVA pads 54 ranging from 9 mm to 13 mm thickness.
[0047] 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.
[0048] As seen in
[0049]
[0050] 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
[0051] As seen in
[0052] 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.

[0053]
[0054] In yet another embodiment, a unitary dorsal section 40 of glove 2 for the embodiment of
EXAMPLE 2
Textile Reinforced Compression Molded Foam Rubber Dorsal Panel
[0055]
[0056] 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.
[0057] 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.
[0058] 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
[0059] 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.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] 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.
