FINGER SUPPORTS AND GLOVES INCORPORATING THE SAME

Abstract

A finger brace is configured for disposition about a lengthwise portion of a human finger between a brace proximal and distal ends. When installed for bracing, the proximal end is anchored at least partially about the outer side of the finger at a location behind the PIP joint. The distal end includes a shank configured for coextension along a lengthwise portion of the outer side of the finger between the PIP joint and the finger nail. Situated between and connecting the support proximal and distal ends is a PIP-joint support that at least partially encircles and supports the PIP joint. In various configurations, a finger brace is incorporated into each glove finger of a sports glove to define a larger overall finger support system. The shanks may be articulated to promote finger bending while preventing rearward hyperextension.

DETAILED DESCRIPTION

[0026] The following description of variously embodied proximal interphalangeal joint and collateral ligament finger supports, and sports gloves incorporating the same, is demonstrative in nature and is not intended to limit the invention or its application of uses.

[0027] Accordingly, the various implementations, aspects, versions and embodiments described in the summary and detailed description are in the nature of non-limiting examples falling within the scope of the appended claims and do not serve to restrict the maximum scope of the claims. Moreover, among the various depicted embodiments, like reference numbers are used to refer to similar or analogous components.

[0028] Referring initially to FIGS. 1-3, various views of a proximal interphalangeal joint and collateral ligament finger support 10 are shown. For the sake of brevity and simplicity, a proximal interphalangeal joint and collateral ligament finger support 10 may be alternatively referred to as finger support throughout the summary and detailed description, as well as the claims. Additionally, the proximal interphalangeal joint is alternatively referred to as the PIP joint.

[0029] A first embodiment of a finger support 10 includes a finger brace 20 configured for disposition about and along a lengthwise portion of a human finger 200, the lengthwise extent of which is indicated by longitudinal axis AL in each of FIGS. 2 and 3. For purposes of establishing referential spatial orientations within the environment of use, the finger 200 is regarded as including an upper or finger outer side 210 corresponding to the finger-nail side of the finger 200, and a lower or finger inner side 220, opposite the finger outer side 210, and corresponding to the palm-side of the hand. Additionally, as one would expect, the lengthwise extent of the finger 200 is defined to extend between a finger proximal end 230 that is closest the main portion of the hand including the palm (not shown) and a finger distal end 240 (alternatively, fingertip 240) that includes the finger nail 242. As shown in FIG. 2, the PIP joint 260 is the jointor knucklesituated between the first (also called proximal) and second (intermediate) phalanges 270 and 280 of the finger 200.

[0030] Returning now to the finger brace 20, a brace proximal end 30 is configured for situating at least partially about the finger 200 at a location that is both behind the PIP joint 260 and at least on the finger outer side 210 of the finger 200. A brace distal end 70 includes an elongated shank 80 configured for coextension along a lengthwise portion of the finger outer side 210 forward of the PIP joint 260. For example, when one version of the finger brace 20 is properly installed about the finger 200, the elongated shank 80 extends between the PIP joint 260 and the finger nail 242. Extending between and connecting the brace proximal end 30 to the brace distal end 70 is a PIP-joint support 50 which is configured to at least partially encircle and support the PIP joint 260 while allowing the PIP joint 260 to bend.

[0031] The specific version of the PIP-joint support 50 shown in FIGS. 1-3 includes opposing helical first and second bands 52A and 52B. The helical first and second bands 52A and 52B are opposing or opposed in the sense that one of the bands 52A and 52B is a right-handed helix, while the other is a left-handed helix. Moreover, the helical first and second bands 52A and 52B at least partially co-extend along the longitudinal axis AL and are cooperatively configured such that, when the finger brace 20 is properly installed about the finger 200, (i) each of the first and second helical bands 52A and 52B encircles at least a portion of the finger 200; (ii) the first and second bands 52A and 52B cross one another at a band-crossing point 54 located to the inside of the PIP joint 260 on the palm side of the hand; and (iii) as viewed from a side, the first and second bands 52A and 52B mutually diverge away from the band-crossing point 54 on the finger inner side 220 and to locations situated on the finger outer side 210 behind and forward of the PIP joint 260.

[0032] Still more specifically, the first and second bands 52A and 52B cooperate to form a PIP-joint support 50 that, when viewed from a side, as in FIG. 2, resembles a V and, when viewed from the top, as in FIG. 3, resembles a figure 8. The PIP joint 260 is supported from underneath, at or near, the bend point 262 of the knuckle by the crossing first and second bands 52A and 52B, while, on the finger outer side 210, the PIP joint 260 is supported forward and rearward of the bend point 262. On the upper, finger outer side 210, the bend point 262 of the PIP joint 260 is not covered by any portion of the PIP-joint support 50 of the present embodiment, an aspect that facilitates bending of the finger 200 at the PIP joint 260. On the lateral sides of the finger 200 (between the finger outer and inner sides 210 of 220), the PIP joint 260 is laterally supported mostly forward of and rearward of the bend point 262 until, near the very bottom of the V, the first and second bands 52A and 52B converge toward their crossing location 54 on the underside of the knuckle on and along the finger inner side 220.

[0033] Although, as indicated above, and in FIGS. 1-3, the finger brace 20 can be used as a stand-alone support device, alternative implementations call for its incorporation into a finger support system 15 that further includes a glove. More specifically, with reference to the cross-sectional view of FIG. 4, a glove finger 105 is configured for insertably receiving a human finger 200 and the finger brace 20 installed about the finger 200. The glove finger 105 includes glove-finger exterior and interior surfaces 106 and 108. Glove-finger upper and lower surfaces 110 and 120 extend along the exterior of the glove finger 105 and correspond, respectively, to the finger outer and inner sides 210 and 220 of a human finger 200 inserted therein. Since they are defined to extend along the exterior of the glove finger 105, the glove-finger upper and lower surfaces 110 and 120 can be regarded as sub-surfaces or surface portions of the glove-finger exterior surface 106.

[0034] The glove finger 105 has defined therethrough a transverse opening 115 (e.g., incision, slit or slot) situated and configured to accommodate the protrusion of the shank 80 of the finger brace 20 therefrom. More specifically, when the finger brace 20 is properly installed about the finger 200, and the glove is disposed over the hand, the PIP-joint support 50 is situated to the interior of the glove finger 105, while the shank 80 of the finger brace 20 protrudes through and forwardly from the transverse opening 115 for disposition along the glove-finger upper surface 110 and the finger outer side 210 forward of the PIP joint 260 with a portion of the glove finger 105 situated between the shank 80 and the finger outer side 210. The protrusion of the shank 80 of the finger brace 20 facilitates a user's adjustment of the finger brace 20 about the finger 200 by means of the shank 80 without requiring removal of the glove from the hand.

[0035] In alternative implementations of a finger support system 15 cooperatively incorporating both a finger brace 20 and a glove finger 105, the shank 80 of the finger brace 20 is secured to the glove-finger exterior along the glove-finger upper surface 110. In some instances, the shank 80 is permanently secured to the glove-finger upper surface 110 while, in other instances, the shank 80 may be temporarily secured to the is glove-finger upper surface 110. Temporary securement may be achieved, by way of non-limiting example, through the use of at least one of (i) adhesive tape, (ii) an elastic band and (iii) a plurality of hook-and-loop fasteners, such as those most commonly marketed under the tradename Velcro.

[0036] In still additional implementations, a finger support system 15 includes a glove-finger 105 and finger brace 20 cooperatively preconfigured such that the shank 80 of the finger brace 20 protrudes through a transverse opening 115 in the glove finger 105 and extends along the glove-finger upper surface 110. Moreover, the finger brace 20 is secured to at least one of the glove-finger outside exterior and inside interior surfaces 106 and 108 with the PIP-joint support 50 aligned and oriented within the glove finger 105 such that the glove can be placed on a user's hand and the finger 200 to be braced inserted into the proximal end 30 of the finger brace 20 until the PIP joint 260 is situated for support within the PIP-joint support 50. In other words, in a preconfigured embodiment of this latter type, the glove finger 105 and finger brace 20 are joined and provided as a pre-assembled single, cooperatively-functioning unit into which a user inserts his or her finger 200 as the glove of which the glove finger 105 and finger brace 20 are an integral part is pulled onto the user's hand. This is distinguishable from scenarios in which a user first installs the finger brace 20 about the finger 200 to be braced and then, subsequently, inserts the already-braced finger 200 into the glove finger 105.

[0037] Although embodiments of finger support systems 15 including both a finger brace 20 and a glove finger 105 are depicted and described principally with reference to a single one of each of (i) a finger 200 to be braced, (ii) a finger brace 20, and (iii) a glove finger 105, it is to be understood that finger support systems 15 incorporating a plurality of finger braces 20 carried by a corresponding plurality of glove fingers 105 of a single glove are expressly within the scope and contemplation of the invention.

[0038] Referring now to the side view of FIG. 5, an alternatively configured finger brace 20 is shown and described. In several key respects, the finger brace 20 of FIG. 5 is is configured similarly to those of FIGS. 1 through 4 and, to the extent that is true, like reference characters are used to reference correspondingly similar elements. As previously described, the finger brace 20 is configured for disposition about and along a lengthwise portion of a human finger 200 including a finger outer side 210, a finger inner side 220, a PIP joint 260 and a fingertip 240 bearing a finger nail 242. Since components and elements of the finger brace 20, and their relative positions as forward, rearward, inner, outer, etc. are best understood with reference to the environment in which the finger brace 20 is properly situated on a human finger 200, the finger brace 20 is thusly shown and described, unless otherwise noted or rendered obvious by context.

[0039] The finger brace 20 includes a brace proximal end 30 situated at least partially about the human finger 200 at a location behind the PIP joint 260 and on the finger outer side 210. Extending forwardly of the brace proximal end 30 toward the fingertip 240 is a brace distal end 70. As with the versions previously described, the finger brace 20 presently under consideration includes a PIP-joint support 50 extending between the brace proximal and distal ends 30 and 70. Additionally, the PIP-joint support 50 is configured to at least partially encircle and support the PIP joint 260 while allowing the PIP joint 260 to bend.

[0040] While the version of FIG. 5 also includes an elongated shank 80 coextending with a lengthwise portion of the finger outer side 210 between the PIP joint 260 and the finger nail 242, there are notable differences between the present version and that of FIGS. 1 through 4. Most notably, the elongated shank 80 of FIG. 5 is articulated. More specifically, the elongated shank 80 which, like the shanks 80 of previously disclosed configurations, includes a shank outside surface 82 and a shank inside surface 84 opposite the shank outside surface 82 and more proximate the finger outer side 210 than is the shank outside surface 82. However, the shank outside surface 82 is defined by (or defines) a plurality of mutually adjacent armor segments 90 (alternatively, ridges) separated by grooves 92.

[0041] With continued principal reference to FIG. 5, but also to FIGS. 5A and 5B, each armor segment 90 includes an outwardly-facing segment top surface 94 and segment front and rear surfaces 96 and 98. Moreover, each segment front and rear surface 96 and 98 defines a portion of one of the grooves 92 separating the armor segment 90 of which it forms a part from an adjacent armor segment 90. As shown in FIG. 5A, the armor segments 90 and grooves 92 are configured and mutually situated such that the finger 200 supported by the shank 80 can bend forwardor inwardtoward the palm.

[0042] Importantly, however, the configuration and relative locations of the armor segments 90 and groves 92 act to prevent the finger 200 from bending backward beyond a predetermined extent by action of the mutual contacting engagement of segment front and rear surfaces 96 and 98 of neighboring armor segments 90, as shown in FIG. 5.

[0043] Another notable difference between the version of FIGS. 5-5B and those of FIGS. 1-4 relates to the longitudinal extent of the shank 80 along a human finger 200. More specifically, in the version of FIGS. 5-5B, the shank 80 originates from the brace proximal end 30 at a location behind the PIP joint 260. From the brace proximal end 30, the shank 80 extends forwardly over the PIP joint toward the finger nail 242 in proximity to which the shank 80 terminates and defines the extreme distal portion of the brace distal end 70. This configuration, by extending over the PIP joint 260, provides support and protection of the finger 200 over a greater length. It is to be appreciated that alternative versions including either the greater shank length or wherein the shank 80 is articulated are within the scope and contemplation of the invention.

[0044] As with the versions of FIGS. 1-4, a version including an articulated shank 80 such as that of FIGS. 5-5B can be incorporated into a larger overall finger support system 15, and, more particularly, as shown in FIG. 6, a finger support system 15 in which at least one of the finger braces 80 is integrated within a glove 100 including a plurality of glove fingers 105. Although gloves 100 wherein each of the five glove fingers 105 includes a finger brace 20 having a shank 80articulated or notare contemplated and included within the claimed scope of the invention, the illustrative version of FIG. 6 depicts for descriptive purposes a glove 100 including only two such glove fingers 105. Additionally, FIG. 6A is a cross-sectional side view of one of the glove fingers 105 having an articulated shank 80 as shown in FIG. 6.

[0045] With conjunctive reference to both FIGS. 6 and 6A, the glove 100 includes a glove-body wall 102, a glove-back side 103, and a glove-palm side 104. The glove-body wall 102 defines the glove-back and glove-palm sides 103 and 104 that extend over the main portion of a human hand as well as the glove fingers 105. As previously explained of single glove finger 105 in connection with alternative configurations of the finger brace 20, each glove finger 105 includes glove-finger exterior and interior surfaces 106 and 108. Glove-finger upper and lower surfaces 110 and 120 extend along the exterior of the glove finger 105 and correspond, respectively, to the finger outer and inner sides 210 and 220 of a human finger 200 inserted therein. Since they are defined to extend along the exterior of the glove finger 105, the glove-finger upper and lower surfaces 110 and 120 can be regarded as sub-surfaces or surface portions of the glove-finger exterior surface 106. Also readily apparent is that the glove-back side 103 and glove-palm side 104 correspond to, respectively, the glove-finger upper and lower surfaces 110 and 120 of each of the plural glove fingers 105.

[0046] Referring principally to FIG. 6A, it will be appreciated that at least a portion of at least one of the shank 80 and the PIP-joint support 50 is disposed along the glove-finger upper surface 110. In this case, the entirety of the shank 80 is disposed along the glove-finger exterior surface 106, but it is to be understood that configurations in which all or part of the shank 80 are disposed internally (to the inside of glove-finger interior surface 108), or even encased within the glove-body wall 102 between the glove-finger exterior and interior surfaces 106 and 108, are within the scope of the appended claims except to the extent that explicit claim limitations to the contrary are recited.

[0047] Referring now to the PIP-joint support 50, in the example of FIG. 6A, the PIP-joint support 50 is disposed about the glove-finger exterior surface 106. However, it is to be understood that, as with the disposition of the shank 80, this is non-limitingly illustrative. As with the shank 80, the PIP-joint support 50 could be partially or entirely disposed about and to the inside of the glove-finger interior surface 108. Moreover, although configurations in which the PIP-joint support 50 is an element separately identifiable from the glove finger 105, included within the scope of the overall inventive concept is at least one embodiment in which the glove finger 105 itself is the PIP-joint support 50, with the shank 80 being the only element of the finger brace 20 that is identifiable separately from the glove finger 105. In a case of the later type, for example, the PIP-joint support 50 does not include first and second bands 52A and 52B, but might otherwise appear generally similar to the example of FIG. 6A, whether or not the shank 80 is articulated.

[0048] As shown in the cross-sectional view of FIG. 6A, the glove 100 carrying one or more finger braces 20 may optionally further include an over-layer 130 of hand-protective padding 135 on at least the glove-palm side 104. Although only a cross-section of the a glove finger 105 is shown in FIG. 6A, it is to be understood that, although not shown, the over-layer 130 mayand preferably doesextend over the glove-palm side 104 of the main body of the glove 100 as well. In the example of FIG. 6A, the over-layer 130 extends over the glove-finger lower surface 120, curves about the fingertip 240 of a wearer's finger 200 and meets the shank 80 on the glove-finger upper surface 110. Although the hand-protective padding 135 can be fabricated from various alternative materials, non-limiting examples include as least one of (i) foam, (ii) rubber, (iii) a polymeric material, (iv) genuine leather, (v) synthetic leather, and (vi) a gel.

[0049] The foregoing is considered to be illustrative of the principles of the invention. Furthermore, since modifications and changes to various aspects and implementations will occur to those skilled in the art without departing from the scope and spirit of the invention, it is to be understood that the foregoing does not limit the invention as o expressed in the appended claims to the exact constructions, implementations and versions shown and described.
