The present invention relates to a heated football glove that is carefully designed to provide warmth to a football player's hands when performing in cold weather or severe weather conditions.
The prior art in general does not address the need for a football glove for use in extreme cold and wet weather. Prior art gloves designed for golf, baseball, or other sports do not suffice because they are not provided with the appropriate tightness of fit, impact resistance or adhesion properties for grasping or catching a ball.
In particular, for players on offense, football gloves need to be designed with the goal of maintaining ball control, primarily to facilitate catching the ball and or holding onto it when being tackled. For example, U.S. Pat. No. 6,065,155 discloses a football glove that includes a glove body having first and second regions, the first region including approximately the front half of the glove including the front half of all the fingers and all of the thumb region, the first region having a rubber-like softened PVC surface layer which is waterproof and has characteristics to improve catching of the football.
In addition to the use of tack material on the palm and fingers to assist in catching or grasping the ball, conventional high performance football gloves also provide a variety of additional features and benefits to protect the wearer's hand, improve comfort, and enhance performance, including:
While the foregoing designs and materials are useful in warm or moderate weather or when playing under a dome or indoors, they do not help the wearer keep his hands warm when the game is played on an outdoor field in cold or frigid weather with or without rain, snow and sleet. In particular, the breathable construction of the glove does not help keep the wearer's hands warm when exposed to very cold or frigid weather conditions. Also, when exposed to rain or snow conditions, moisture can enter into the glove through the breathable or mesh areas, thus detrimentally affecting the feeling and condition of the wearer's hands and the ability of the player to properly perform.
The use of heating in various gloves is disclosed in a number of patent documents, including U.S. Pat. Nos. 3,606,614, 4,543,671, 4,764,665, 4,950,868, and 6,141,801 and US patent application 2004/0244090. None of these gloves, however, are suitable for use as a football glove, nor can they be modified for use in a football game.
A summary of general football gloves that are designed to provide warmth to the user's hands can be found in US patent publication 2011/0214221. None of the gloves disclosed in that application have any kind of heating means, however, such that their use in extremely cold weather is generally ineffective. And as a player's hands become cold due to exposure to low temperatures for extended periods of time, they are not able to properly catch or hold onto the football with dropped passes or fumbles as a result. Thus use of a tack coating provides some benefit but it cannot completely compensate for or remedy the disadvantages of extremely cold hands that are trying to catch or hold a ball.
Thus, there remains a need for a football glove that can be used in cold and wet weather conditions which provides the appropriate fit, warmth for the hands and appropriate surface properties to facilitate handling of the football. The present invention now satisfied these needs.
Accordingly, the present invention now provides a heatable football glove that provides heat to a wearer's hand comprising a body member for covering a person's hand including palm, finger, thumb, knuckle, wrist and back side portions, wherein the thumb and finger portions fully cover the person's fingers. The body member has an opening on the back side portion and a pocket member is provided beneath the back side portion of the body member. The pocket extends from the knuckle portion to the wrist portion and is accessible through the back side portion opening. The pocket is configured and dimensioned to cover the user's knuckles and to extend to the wrist portion. Also, it is securely attached to the glove to avoid movement in the glove during use.
The glove includes a heating element comprising a pouch that encloses a heat generating material that is activated by contact with air, wherein the heating element is configured and dimensioned to be of substantially the same size as the pocket such that the heating element after activation is snugly received in and conforms to the pocket in order to be retained therein substantially without movement during use of the glove. A covering member is also provided for closing the opening and retaining the heating element in the pocket during use of the glove. In particular, the covering member is selectively removable from a first position where the opening is exposed to allow insertion or removal of the heating element therein or therefrom, to a second position where the covering member closes the opening and is attached or adhered to the glove. Additionally, an attachment member is associated with the covering member and wrist portion of the glove for releasably attaching or adhering the covering member to the glove to retain the heating element in the pocket during use of the glove.
Advantageously, the heating element and pocket are provided with a generally rectangular shape that conforms to the back of the users hand and with tab portions that extend from sides of the rectangular shape and over the users knuckles. Additionally, the tab portions of the heating element and pocket are rounded and do not extend into the finger portions of the glove, and wherein the pocket is secured in place by stitching to the body member. As a further feature, the heating element and pocket are configured to include side portions or wings that cover the sides of the wearer's hand from the index finger portion to the thumb portion and from the pinky finger portion towards the wrist portion.
The covering member is generally shaped to conform to the back portion of the hand and the attachment member preferably comprises hook and loop fasteners, snaps, a zipper or buttons and buttonholes, with part of the attachment member provided on the covering member and a mating part provided on the back portion of the glove to allow the covering member to be releasably attached to the back portion of the glove. One end of the covering member is permanently affixed to the back portion of the glove while the opposite end includes part of the attachment member, with the back portion of the glove including a mating part of the attachment member in position to receive the covering member in snug contact therewith over the opening and against the back portion of the glove.
The covering member may be affixed to the glove by a seam that extends substantially horizontally from below the index finger portion to the pinky finger portion beneath the knuckle portion with the attachment member provided in the wrist portion and with the pocket opening extending substantially horizontally in a position below the first finger to below the pinky finger portion.
Alternatively, the covering member may be affixed to the glove by a seam that extends substantially vertically from below the index finger portion to the wrist portion with the attachment member provided in a vertical orientation extending from below the pinky finger portion to the wrist portion with the pocket opening extending vertically between the second and third finger portions.
Preferably, the glove further comprises a continuous or discontinuous tacky material, coating or layer on the palm portion of the glove including the palm area and the palm side of the thumb and finger portions. This is especially desirable for gloves that are to be used by running backs or receivers. The tacky material, coating or layer is present upon and preferably completely covers the palm side of the glove including the palm portion and the thumb and finger portions.
The back side portion of the glove conveniently includes a layer between the pocket and outer surface that includes or is made of a heat reflecting material so that the heat emanating from the heating element is directed back towards the wearer's hand.
The wrist portion of the glove generally includes a closure element for tightening the glove onto the wearer's wrist to prevent dislodgment of the glove during use.
The features and benefits of the present invention are better understood by a review of the following detailed description which is provided along with the appended drawing figures wherein:
The present invention relates to a football glove which is specifically design for and used when playing or practicing football. A football glove must be rugged as well as durable as it experiences contact, impact, abrasion, moisture, dirt or mud and other actions or conditions that affect the performance of the glove. The construction of the glove is selected such that is conforms closely to the user's hand and it tightened thereof by a wrist strap. Additionally, the provision of a heating element that snugly fits within a pocket in the glove that maintains the element in the position for heating the back of the wearer's hand without movement during use throughout the game due to contact or impact. The heating element and pocket are configured to essentially the same dimensions to hold the element in the pocket in the correct heating position.
To help understand the invention and the orientation of the component parts of the glove, the following designations will be used. As shown in the drawings, the glove includes a body member that is shaped in the same way as a user's hand so that for convenience the glove of the present invention will be described with portions that correspond to the parts of the human hand that it contacts.
The glove includes a body member that snugly fits an average user's hand for the sizes mentioned. The body member will include finger portions for covering each finger, including an index finger portion, second finger portion, third finger portion and pinky finger portion, a thumb portion for covering the thumb, a wrist portion for covering at least a portion of the wearer's wrist, a palm portion for covering the area between the finger and wrist portions on the front side of the user's hand and a back side portion for covering the back side of the user's hand from the finger portions to the wrist portion including a knuckle portion for coverage of the wearer's knuckles. The front of the glove that covers the palm and front sides of the fingers will be referred to as the palm side of the glove while the back of the glove that contacts the back side of the hand and fingers will be referred to as the back side portion of the glove. The glove also includes a side portion that covers the side of the hand between palm and back side extending from the end of the index finger portion to the thumb portion and an opposite side portion that covers the side of the hand between palm and back side extending from the pinky finger portion to the wrist portion.
The football gloves of the present invention improve the player's performance on the gridiron by providing heat and warmth to their hands in extreme weather conditions while also protecting the backs of their hands from impact as well as providing extra grip to control the ball. These gloves also provide additional features such as light weight, flexibility, and a conformance fit. There are slightly different football gloves according to the invention depending upon the player's position. These include:
Receivers and Running Back Gloves—Receivers and running backs need to control and hold onto the ball, while remaining light weight. Gloves designed for these players feature:
Lineman Gloves—Lineman take the hardest repetitive and almost constant hits on the field, so their gloves are built tougher, to protect their hands and fingers from damage, abrasion, and hyperextension. Most lineman gloves feature:
The following conventional groves are typical of preferred football gloves for use by both professionals and amateurs. The basic construction of each glove is suitable for use in the present invention, with each glove being redesigned to have sufficient internal space to accommodate the pocket and heating element, and with the outer layer including a pocket opening and covering member. These conventional gloves include:
Under Armour F3 Gloves that feature a super-sticky Armour® GrabTack palm and rollover thumb. A seamless, one-piece palm with numerous perforations helps eliminate sweat build-up. Additional features of this glove include a breathable, ultra-light and durable stretch woven construction for the back side portion, a construction that secures thumbs and index fingers to reduce twisting, reflective trip details for visibility, and a molded CompFit wrist cuff with closure tab for securing the gloves on the player's hands. Under Armour also makes Nitro Gloves, which has many of the same features found in the F3 Gloves but with additional differences with regard to the details of the reflective trim.
Nike Vapor Jet 2.0 Football Gloves, which are built with Magnigrip CL material between the fingers and on the palm to deliver superior grip and durability in all conditions. It also includes an ultra-light construction that includes a gusset system for greater range of motion, catching surface area and control, an adjustable wrist strap with hook and loop (VELCRO® brand) fasteners for a locked-down fit, and pre-curved fingers for reduced bunching, increased grip area and a more natural fit. The glove material is 62% polyester/18% nylon/12% silicone/8% neoprene.
Adidas Supercharge 2 Gloves which offer a GripTack Palm, delivering a dual-coated treatment that performs in all weather conditions. Lightweight, multidirectional stretch compression and a smooth neoprene band allows this glove to provide a fit that moves with the fingers, palms, and wrists. It also includes vented mesh finger inserts and an expansion recess between thumb and index finger.
Cutters C-Tack Revolution Glove which features an exclusive and proprietary C-TACK™ Revolution Performance Grip Material to provide the best combination of performance and durability in a glove that provides an improved fit and a lighter weight. The glove performs in all weather conditions and is also machine washable and dryable.
Each of the foregoing gloves discloses different tack coatings or layers which are eminently suitable for use in the present invention. And while breathability of the back side of the hand is not preferred for use in the present invention due to potential heat loss from the heating element, many of the other features of such gloves are desirable for use in the present invention. The final construction of the glove can depend upon the desires of a skilled artisan in developing an optimum glove for a particular performance situation, i.e., to protect the player's hands against frigid cold, wet snow, or combined rain/snow conditions during a game that is played outdoors rather than in a dome. For this reason, one or more of the various features of existing gloves can be incorporated into the heatable football gloves of the present invention.
For running back and receiver gloves, the most important additional feature to include is the tack coating or layer on the palm side of the glove to facilitate catching and holding onto the ball when running or being tackled. Different glove manufacturers design their gloves with different types and styles of palm grip tack material to provide different levels of tackiness and control on the ball. These gloves are particularly designed for receivers and running backs. The following are popular varieties of grip surfaces for use in the present invention:
Cutters C-Tack layer, because it provides a robust and permanent tacky grip that actually restores when washed or cleaned.
Nike Magnigrip CL, which delivers a solid grip and lasting durability during use.
Armour GrabTack, which provides an extremely sticky grip that is extended over the thumb for added ball control.
Adidas Seamless Double-Coated High-Gloss Silicone Palm which also provides a solid grip of silicone material that extends around the thumb.
Neumann Tackified Leather Palm, which is a basic thin treated leather palm grip for gloves that fit tightly, giving players a natural feel and grip on the ball.
The material on the palm of the glove can be treated or coated to enhance catching and gripping abilities. Generally, conventional football glove palms are either made of latex or cabatta leather, a thin leather material that is treated with chemicals that increase tackiness and provide a better ball grip. This leather material is also extremely soft, flexible and durable. Gloves with latex palms provide the best fit and flexibility but are not as durable and can get slippery in wet weather. This is why the present invention prefers to include one of the premium tack coatings or layers described herein on the palm side of the glove.
The most preferred tack or grip material used on the gloves of the invention is the Cutters' C-Tack layer, because this material is provided as a layer that forms part of the palm side of the glove rather than a coating such that it does not wear away quickly and it can be wiped down after use or even cleaned in a washing machine after use.
The palm portion and finger portions on the palm side of the glove are generally uniformly coated or provided with a coating or layer of the tack material. Depending upon the precise weather conditions expected when used, e.g., a cold but dry day, the players may also use gloves that have a discontinuous or patterned application of grip material on the palm and finger portions, and those configurations are also included as additional embodiments of the present invention. As a skilled artisan is well aware of the various tack coatings or layers that are available, these are not specifically illustrated by the drawings.
Referring now to the drawing figures,
As shown in more detail in

Alternatively, for these embodiments, the heating element can be configured in a generally rectangular shape that conforms to the approximate size of the backside portion of the glove to provide heat to the entire back side of the wearer's hand. This rectangle would have dimension of 6 to 9 cm wide and 5 to 8 cm long. A circle, ellipse or polygon shape can also be used but these are not preferred to the rectangle or
For any of the heating element embodiments, the pocket in the glove that receives the heating element will be sized and shaped to conform closely to the size and shape of the heating element 150, preferably an preferably in contact with the inner periphery of the pocket. The heating element is inserted into the pocket through opening 120 as shown by the arrow in
While a simpler construction for the heating element and pocket is possible, it is preferred for the outer perimeter to be more complex so that the pocket can retain the heating element therein without movement during use. The covering member also assists in tightening the pocket and heating element against the back of the wearer's hand so that it does not move during use of the glove during a game.
The preferred heating element is one that includes an air activated composition that is generally a mixture of iron powder, charcoal, salt, sawdust, and vermiculite. The composition is provided in a fabric, paper or plastic sheet or film structure of desired dimensions with the sheet or film having sufficient porosity to allow air and oxygen to enter therein to activate the mixture so that it can generate heat. The mixture is non-toxic and odorless and the heating element functions as a non-electrical and non-fuel burning element which generates and transmits heat energy to the hand of the wearer. The structure and composition are provided in a sealed pouch until use, and can be activated simply by opening the pouch and removing the structure from the pouch. When exposed to the air, an oxidation process takes place in the mixture to generate heat, and depending upon the formulation, these products can generate heat for up to 10 to 20 hours or more. For the present invention, that would be more than enough as a heat generating time of about 5 to 6 hours usually would be more than sufficient to last throughout a game.
In a preferred embodiment, the upper recesses of the pocket and lower and 195 are sewn or otherwise secured to the inner lining or inside of the glove so that the pocket cannot move during use. The sides that include extended portions 185, 190 or left free to assist in receiving the heating element 150 therein.
As for the construction of the glove itself, the glove body may be of a single ply construction, such as is found in conventional glove liners, with a single ply outer shell which defines tightly fitted finger pockets, a thumb pocket, and the palm and back side portions for contacting the hand. The shell may optionally extend proximally beyond the palm and back side portions to a wrist portion that covers the user's wrist. The outer shell is made of a water resistant material or structure that prevents water from passing through the outer shell.
The specific construction of the football gloves of the invention can also vary depending upon the manufacturer's preferences. Generally, the outer layer or shell are made of leather because this material is comfortable and is very flexible, so they do not hamper the wearer's grip or performance. The gloves of the present invention may have an outer shell of any suitable material although a leather glove of substantially conventional external design and construction is preferred.
In a preferred embodiment of the invention, the glove body has a two-ply construction that includes the outer shell and an inner liner or layer of a suitable fabric. This combination provide greater comfort when the wearer's hand is placed into the form fitting glove. Preferably, the inner shell is thin, e.g. 1-5 mm and more preferably 2-4 mm, in uncompressed thickness, to provide comfort along with good flexibility and tactile sensitivity. The inner, lining layer or shell may be constructed from a variety of materials, such as cotton, nylon, wool, polypropylene, SPANDEX® or other natural or synthetic fibers of similar texture and flexibility commonly used in the textile industry. The selection of materials, weaves, and shell thicknesses will also depend on the type of glove (i.e., lineman or running back, etc.) as these have different insulation requirements, whereby the shell must provide for effective transmission of heat from the heating element to the hand while at the same time insulating the wearer against discomfort or burns due to excessive heat transmission. In this two-ply configuration, the outer layer or shell is shaped and dimensioned to cover and closely conform to the inner, lining, and thus is defined with similarly shaped, but slightly larger finger pockets, thumb pocket, and palm, back side portions, and wrist portions.
In this regard, it is noted that a receiver or running back glove would desirably be thinner so that an additional layer of fabric would not be preferred. For lineman gloves, additional layers would be acceptable to provide additional protection for their hands.
The pocket and heating element can be provided in either the single or two ply glove constructions in any one of a variety of ways. The simplest arrangement is to provide the pocket as a separate component which is sewn, stitched or otherwise adhered to the inside of the single ply or double ply glove. Having the pocket entirely separate from the inner lining and the outer layer, allows the pocket to have all sides continuously joined together to form the pocket but with only certain portions of the periphery or boundary attached, e.g., by sewing or stitching, onto one or preferably both layers of the glove.
Alternatively, in a two-ply glove construction, the heating element can be positioned in a pocket that is formed between an inner liner and the outer layer. This, for example, would allow for placement of the heating element directly against an outer surface of the inner shell with the inner liner providing a fabric surface between the wearer's hand and the heating element. The pocket is formed by sewing or stitching the inner lining to the outer layer in a pattern that provides an outline that matches that of the heating element.
In another aspect of the two-ply glove design, the pocket and heating element are provided between the inner, lining layer and the wearer's hand. In this embodiment, the pocket is formed by attaching an additional layer of fabric to the inner lining by sewing or stitching in a pattern that provides an outline that or boundary for the pocket that conforms closely to the shape of the heating element. The inner layer is then sewn or adhered to the outer layer in order to help maintain the pocket and heating element in the correct position in the glove.
By “conforms closely” what is meant that the heating element is snugly received in the pocket essentially in contact with the pocket boundary or sewing seams. Of course, a small tolerance of about 1 to 6 mm (up to a quarter inch) and preferably not more than 3 mm (⅛″) is provided to facilitate the introduction of the heating element and to retain the heating element in the correct position in the glove on the back of the hand.
Below the outer shell and heating element is a material that acts as a heat reflector to direct heat emanating from the heating element back towards the wearer's hand. This material may be a reflective foil such as an as aluminized plastic film bonded to the outer layer or upon a support. Depending upon the glove construction, the heat reflective layer can be applied to the back of the inner liner, the inside surface of the upper layer of the pocket, or the inside of the outer layer. It also can be provided on a fabric support that is used in place of or in addition to the inner liner.
The heat reflective layer only needs to be as large as the pocket so that it reflects the heat emanating from the heating element back towards the center of the glove and the back of the user's hand. When a separate pocket is provided, the heat reflective material can be provide just on the inner surface of the upper fabric layer. In other embodiments, if desired for ease of construction or otherwise, the entire inner surface of the back side portion of the inner or outer layer of the glove can be provided with heat reflective material to form a complete layer.
A number of other materials are useful as the heat reflecting material or layer. This includes a metalized layer of a fabric or other flexible substrate that includes a deposit of a metallic material on one surface to form a relatively thin metal coating. The metalized layer is positioned in the glove with the metalized surface outside of the heating element and pocket so that as much of the heat generated by the heating element is reflection by the metal coating back towards the wearer's hand. The metal coating may be formed by vapor deposition although other processes for applying a metal coating to the substrate through thermal bonding, chemical bonding, laminating or any form of adhesive can also be used. Preferably, the metallic material used for the metal coating is aluminum which is applied to a surface of substrate. The substrate of the metalized layer can also be mylar, or a thin sheet of plastic such as polyethylene terephthalate (PET) as these can reflect up to 97% of the radiant heat it receives on its surface. Other materials that can be used for the substrate are polyester, spandex, fleece, lycra, cotton, nylon, wool, acrylic, rayon fabric or any combination of such materials in a blended fashion.
To further direct the heat generated by the heating element towards the finger portions of the glove, a controlled venting arrangement can be provided.
And as noted herein, the covering member 105, 305 can be provided at any suitable location on the back side of the glove to cover and close the pocket which receives the heating element. A preferred arrangement is a covering element that has a flap which is sewn on one side to the glove and on the opposite side can be secured in place on the glove by a hook and loop fastener, such as that sold under the trademark “Velcro”. Other suitable fasteners may be used, such as snaps, zippers, button and button-holes or the like. The hook and loop fastener arrangement is preferred for ease of use and to facilitate quick changes such as when the heating element is spent and needs to be replaced during a game, as this can be done rapidly during a timeout by the equipment manager. The closure can be peeled off easily for removal of the spent heating element and for the introduction of a new one before closing the opening with the hook and loop closure.
The opening 120,320 that provides access to the pocket is shown as substantially horizontal or substantially vertical in the preferred embodiments. Of course, any particular opening orientation can be used provided that it can provide access to the pocket. One preferred feature of the invention is to provide the opening with a small width in order to prevent heat losses through the opening. While the covering member assists in retaining heat in the glove, the thin width of the opening also helps this while not presenting a problem for the introduction of the heating element because the outer shell of the glove typically has some stretch and give to allow the flexible heating element to be passed therethrough. Of course a skilled artisan can best determine the size of the opening to facilitate the introduction and removal of the heating element. Also, when larger size openings are desired, the underside of the covering member 105,305 can be provided with a heat reflecting layer to help maintain the heat in the glove.
In the present invention, in addition to retaining the heating element inside the pocket, the covering member also may be designed with padding to assist in protecting the wearer's hands from impact or contact. This feature is more desirable for a lineman or linebacker glove since those players experience more contact on each play. In fact, instead of providing a tack surface on the palm side of the glove, a lineman or linebacker glove could be designed with additional padding on that surface to further protect the wearer's hands during the game.
Accordingly, the present invention accommodates different kinds of football gloves for different playing positions. So while a lineman's glove should be heavily padded on the top and the wrist and even on the palm side, a linebacker would benefit from a glove that is heavily padded but at the same time is more flexible and soft and has at least some tack surface to help when intercepting a pass or falling on a loose ball. Softer and more flexible gloves with a sticky or tacky palm are better suited for running backs and receivers while a defensive back's gloves should not just have the same qualities, but should also be padded on the upper to resist impact.
In view of the wide variety of embodiments to which the principles of the present invention can be applied, it should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the present invention. Furthermore, the claims should be read to cover all embodiments that come within the scope and spirit of the invention including equivalents thereto.
This application claims the benefit of provisional application 62/140,021 filed Mar. 30, 2015, the entire content of which is expressly incorporated herein by reference thereto.
