Abstract:
A batting glove or sports glove includes a glove base configured to accommodate a users hand. In some embodiments, the glove base has an opening in a palmar region of the glove. Multiple palmar layers are attached to the glove base and positioned over the opening. In some embodiments, the palmar layers include a first layer of material positioned between a second layer of material and a third layer of material. The first layer of material has a lower coefficient of friction than one or both of the second and third layers of material such that the layers may slide relative to one another.

Description:
BACKGROUND 
       [0001]    A baseball or softball batter typically swings a bat several times during a game or in practice or training. During a batter&#39;s swing, rapid acceleration and deceleration of the barrel, along with vibrations from impact with a ball, result in strong forces that can damage the fibrous connective tissues, muscles, tendons, and ligaments of the batter&#39;s hands, and can cause blisters, callouses, bruises, open wounds, and even broken bones in the hand. 
         [0002]    Many batters wear a thin batting glove on one or both hands to try to reduce damage to their hands during a swing. But motion of the bat is still transferred through the glove into the user&#39;s hand because the hand, the glove, and the bat are all directly connected. As a result, standard thin batting gloves do not always provide adequate protection for a batter&#39;s hands. 
         [0003]    Other batters choose to wear a thick or padded batting glove on one or both hands. The thickness or padding of the glove acts as more of a barrier or damper to forces from each swing. But the hand, the glove, and the bat remain directly connected. And the thickness or padding reduces a player&#39;s tactile gnosis, which is a cognizance-by-touch form of sensory perception. Successful athletes use tactile gnosis to relate to their equipment as an extension of their own bodies. Thick or padded gloves distance the user from the bat and reduce a batter&#39;s ability to accurately feel and control a swing. Because of these disadvantages, professional and elite batters rarely use thick or padded gloves. 
       SUMMARY 
       [0004]    A batting glove or sports glove includes a glove base configured to accommodate a user&#39;s hand. In some embodiments, the glove base has an opening in a palmar region of the glove. Multiple palmar layers are attached to the glove base and positioned over the opening. In some embodiments, the palmar layers include a first layer of material positioned between a second layer of material and a third layer of material. The first layer of material has a lower coefficient of friction than one or both of the second and third layers of material such that the layers may slide relative to one another. Other features and advantages will appear hereinafter. The features described above may be used separately or together, or in various combinations of one or more of them.

     DETAILED DESCRIPTION 
       [0008]    The present technology is directed to a batting glove with an internal slip layer. Various embodiments of the technology will now be described. The following description provides specific details for a thorough understanding and enabling description of these embodiments. One skilled in the art will understand, however, that the invention may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail so as to avoid unnecessarily obscuring the relevant description of the various embodiments. Accordingly, the technology may include other embodiments with additional elements or without several of the elements described below with reference to  FIGS. 1-2 , which illustrate examples of the technology. 
         [0009]    The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the technology. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this detailed description section. 
         [0010]    Where the context permits, singular or plural terms may also include the plural or singular term, respectively. Moreover, unless the word “or” is expressly limited to mean only a single item exclusive from the other items in a list of two or more items, then the use of “or” in such a list is to be interpreted as including (a) any single item in the list, (b) all of the items in the list, or (c) any combination of items in the list. Further, unless otherwise specified, terms such as “attached” or “connected” are intended to include integral connections, as well as connections between physically separate components. 
         [0011]    Specific details of several embodiments of the present technology are described herein with reference to baseball or softball. The technology may also be used in other sports or industries in which hand protection and a high level of tactile gnosis is advantageous or desirable. 
         [0012]      FIG. 1  illustrates a glove assembly  100  in accordance with an embodiment of the technology. A palmar component  110  is stitched, glued, or otherwise suitably secured to or integrated with a glove base  120 . The palmar component  110  may be shaped to generally correspond with the palmar surface of a user&#39;s hand, including the surfaces of a user&#39;s fingers, or it may be otherwise suitably shaped to provide protection to other desired regions of the user&#39;s hand. For example, the palmar component  110  may be shaped to correspond with areas of the glove assembly  100  that contact sports equipment (for example, a ball bat) when in use. The glove base  120  may be shaped to accommodate a user&#39;s left or right hand. The glove base  120  may be formed from natural leather, synthetic leather, sheepskin, goatskin, microfiber, or other materials suitable for athletic use. The palmar component  110  may be formed from a stack of layers, as described below with reference to  FIG. 2 . 
         [0013]      FIG. 2  illustrates a stack of layers forming the palmar component  110 , according to one embodiment. The palmar component  110  includes an inner layer  200 , a release ply layer  210 , and an outer layer  220 . The layers  200 ,  210 ,  220  of the palmar component  110  may be stitched, glued, or otherwise connected together around their respective perimeters to form the palmar component  110 , which is mounted in the glove base  120 . In some embodiments, the assembled palmar component  110  may be stitched, glued, or otherwise secured into a correspondingly-shaped opening  230  or receiving area in the glove base  120 . 
         [0014]    In other embodiments, the inner layer  200  may be formed as an integral part of the glove base  120 . In other words, in some embodiments, the glove base  120  need not have an opening  230 , and the inner layer  200  need not be a discrete part of the palmar component  110 . In such embodiments, the release ply layer  210  and the outer layer  220  are stitched, glued, or otherwise connected along their respective perimeters to the glove base  120 . 
         [0015]    In some embodiments, the layers  200 ,  210 ,  220  may include stitching, glue, or another attachment along their respective perimeters, while lacking attachment in some interior regions of the layers. For example, in some embodiments, there may be an absence of attachment adjacent to a proximal portion of the palmar surface, a distal portion of the palmar surface, a lateral portion of the palmar surface (for example, a thenar or thenar eminence region of the palmar surface), a medial portion of the palmar surface (for example, a hypothenar or hypothenar eminence region of the palmar surface), or some or all of a digital region (i.e., fingers). In some embodiments, in addition to stitching or another attachment in perimeter regions of the layers  200 ,  210 ,  220 , there may be stitching or another attachment at the base of one or more finger regions. 
         [0016]    The inner layer  200  and the outer layer  220  may be formed from various materials, including materials generally used in sports or batting gloves. For example, the inner layer  200  and the outer layer  220  may be formed from natural leather, synthetic leather, sheepskin, goatskin, microfiber, or other materials suitable for athletic or industrial use. In some embodiments, the inner layer  200  and the outer layer  220  may be formed from the same material, or in other embodiments, they may be formed from different materials. 
         [0017]    The release ply layer  210  may be formed from a thin film or other material having low friction or a low coefficient of friction. In particular embodiments, the release ply layer  210  has a lower coefficient of friction than either or both of the inner layer  200  and the outer layer  220 . For example, in some embodiments, the release ply layer  210  may be 0.002 inches thick and formed from polyethylene film. In other embodiments, other suitable thicknesses and materials may be used, such as polyester film (for example, MYLAR) or fiberglass cloth coated or impregnated with a polymer such as PTFE (for example, TEFLON). 
         [0018]    In use, a ball bat or other implement tends to frictionally engage the outer layer  220 , while the skin of the user&#39;s hand tends to frictionally engage the inner layer  200 . The release ply layer  210  allows all of the layers  200 ,  210 ,  220  to slide with respect to one another, thus providing a slip plane to divert energy and forces from the bat handle. The layers  200 ,  210 ,  220  decouple the bat from the hand along the slip plane so that short forceful impulses and motions of the bat handle and knob are prevented, or substantially prevented, from passing through the glove into the hand. 
         [0019]    In some embodiments of the present technology, the layers  200 ,  210 ,  220  may be generally similar in size. In other embodiments, the layers  200 ,  210 ,  220  may have relatively different sizes among themselves in order to resist bunching or wrinkling of the layers when a user grasps a bat. For example, the outer layer  220  may be smaller (for example, proportionally smaller) than the release ply layer  210 , and the release ply layer  210  may be smaller (for example, proportionally smaller) than the inner layer  200 . In such embodiments, the layers  200 ,  210 ,  220  may still be stitched or otherwise attached around their respective perimeters or in other areas as described above. And in such embodiments, the inner layer  200  may be sized such that a degree of looseness or slack exists in the inner layer  200  when the user&#39;s palm is open, but the looseness or slack tightens when the user grips the round handle of a bat. 
         [0020]    In contrast with existing gloves that absorb energy through padding or increased thickness, the current technology uses thin slipping layers to divert energy along the slip plane without unduly limiting feel or tactile gnosis. Thus, when a user grasps the bat, the palmar component  110  generally feels like one thin layer. Accordingly, the present technology provides a safe batting glove without unduly limiting feel. 
         [0021]    From the foregoing, it will be appreciated that specific embodiments of the disclosed technology have been described for purposes of illustration, but that various modifications may be made without deviating from the technology, and elements of certain embodiments may be interchanged with those of other embodiments. For example, in some alternative embodiments, there may be more than one release ply layer (for example,  210 ). In some embodiments, the stitching, gluing, or other attachment between the layers  200 ,  210 ,  220  or the glove base  120  may be located in areas other than the perimeters of the layers. 
         [0022]    Further, while advantages associated with certain embodiments of the disclosed technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the technology. Accordingly, the disclosure and associated technology may encompass other embodiments not expressly shown or described herein, and the invention is not limited except as by the appended claims.
