## Title
Glove with expansion zones along sides of fingers

## Abstract

A glove, particularly for golf, is provided with a gusset of expandable material which extends along the finger stalls of the glove from the web between the finger stalls to a selected distance from the distal end of the fingers, the glove having a non-expandable material wrap around the fingers thereby providing an expansion zone that extends along the length of the fingers to a selected distance from the tip end of the distal phalanxes of the fingers.

## Background
BACKGROUND OF THE INVENTION
(a) Field of the Invention
This invention relates to gloves for the human hand which are particularly useful in participating in activities which require a snug fit of the glove at the distal end of the fingers. More particularly, this invention relates to a glove specifically designed to provide expandable zones along the lateral sides of the finger stalls of the gloves just distal to the proximal interphalangeal joints of the fingers thereby allowing a glove to expand at the proximal interphalangeal joints providing a snug fit at the distal ends of the fingers.
(b) Description of Related Art
Glove construction for protection of the human hand is well known. Moreover, there are a number of patents which teach gloves and glove construction useful for specific sporting activities, as well as work gloves, dress gloves and the like. For example, U.S. Pat. No. 3,175,226 teaches a glove construction with selected portions of the glove including expansion zones to accommodate hands of different sizes, as well as enlargement of selected areas when bending and flexing the fingers of the wearer. This reference teaches leather or a relatively inelastic palmar side section and an elastic dorsal side section with outwardly extending finger and thumb stalls. The longitudinally extending edges or sides along the finger stalls include an expansion zone of knitted material which extends from the web between the index finger stall and the thumb stall along the entire length of the index finger.
Moreover, for example, U.S. Pat. No. 5,195,188 teaches a golf glove wherein the longitudinal extending areas along the sides of the finger stalls of the glove are made of a material possessing only slight extensibility, such as leather, and the other areas of the finger stalls are made of an extensible, elastic material.
Although, hand protection from direct shock and abrasions is found in gloves of the present art, what is needed is a glove which provides improved grip, comfort and performance by providing a glove with finger stalls which expand at the proximal interphalangeal joint providing with a snug fit at the distal ends of the fingers.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a glove which allows expansion at the proximal interphalangeal joints of the fingers and a snug fit at the distal ends of the fingers.
Another object of the present invention is to provide a golf glove having materials of construction in preselected areas of contact with the fingers of the human hand to provide a snug fit glove for the use in gripping the handle of a golf club.
A further object of the present invention is to provide a golf glove having expansion materials extending along the finger stalls of the glove from the web between the finger stalls to a selected distance from the distal end of the fingers.
More particularly, the present invention provides a glove having a gusset of expandable material extending in a web of the glove between adjacent finger stalls and positioned to terminate between the proximal interphalangeal joints and the distal interphalangeal joints of fingers to be received in adjacent finger stalls.
Further objects and advantages of this invention will appear from the following description and appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a schematic anatomical view of the bones of a left human hand 10 looking at a palm side. Shown are the radius 20, ulna 21, radiocarpal joint (RC) 23′, distal radio ulnar joint (DRUJ) 22, wrist 12, thumb 64, index finger 65, long finger 66, ring finger 67, small finger 68, and the carpus 69. The carpus 69 comprises eight carpal bones, seven of which are shown in FIG. 1, and includes the hamate bone 71 with its hook-like protrusion, the scaphoid 24′ and the lunate 25.
The thumb 64 is comprised of the distal phalanx 51, the interphalangeal joint (IP) 46, proximal phalanx 41, diaphysis of proximal phalanx 41′, metacarpalphalangeal joint (MCP) 36, metacarpal 31, and carpometacarpal joint (CMC) 26.
The index finger 65 is comprised of the distal phalanx 60, distal interphalangeal joint (DIP) 56, middle phalanx 52, proximal interphalangeal joint (PIP) 47, proximal phalanx 42, metacarpalphalangeal joint (MCP) 37, metacarpal 32, and carpometacarpal joint (CMC) 27.
The long finger 66 is comprised of the distal phalanx 61, distal interphalangeal joint (DIP) 57, middle phalanx 53, proximal interphalangeal joint (PIP) 48, proximal phalanx 43, metacarpalphalangeal joint (MCP) 38, metacarpal 33, and carpometacarpal joint (CMC) 23.
The ring finger 67 is comprised of the distal phalanx 62, distal interphalangeal joint (DIP) 58, middle phalanx 54, proximal interphalangeal joint (PIP) 49, proximal phalanx 44, metacarpalphalangeal joint (MCP) 39, metacarpal 34, and carpometacarpal joint (CMC) 24.
The small finger 68 is comprised of the distal phalanx 63, distal interphalangeal joint (DIP) 59, middle phalanx 55, proximal interphalangeal joint (PIP) 50, proximal phalanx 45, metacarpalphalangeal joint (MCP) 40, metacarpal 35, and carpometacarpal joint (CMC) 30.
FIG. 2 shows the skeletal anatomy, pulley system, and flexor tendons of the thumb 64 and fingers 65-68 of the right hand 10. The thumb 64 includes the flexor tendon (flexor pollicis longus) 200 and the three pulleys 220-224 of the thumb 64; an A1 pulley 220, A2 pulley 222, and A3 pulley 224. The A2 pulley 222 is the most important for function and is attached to the proximal phalanx 41 of the thumb 64. The respective pulleys 230-238 are also shown for each of the: index finger 65, long finger 66, ring finger 67, and small finger 68. Each finger 65-68 has five pulleys 230-238; an A1 pulley 230, A2 pulley 232, A3 pulley 234, A4 pulley 236, and A5 pulley 238. The A2 pulley 232 and A4 pulley 236 are considered to be the most important for function. The A2 pulley 232 is attached to the proximal phalanx 42-45. The A4 pulley 236 is attached to the middle phalanx 52-55. The A1 pulley 230 is near the MCP joint 37-40, the A3 pulley 234 is near the PIP joint 47-50 and the A5 pulley 238 is near the DIP joint 56-59.
The flexor tendons 202-208 are shown as one unit for each finger 65-68, but actually there are two flexor tendons to each unit. They are the flexor digitorum superficialis and the flexor digitorum profundus (shown as one, 202-208). These tendons 202-208 travel underneath the pulleys 230-238 and the flexor digitorum profundus tendon attaches to the distal phalanx 60-63 of each finger 65-68. The tendons 202-208 move back and forth below the pulleys 230-238, via muscles (not shown) attached to the proximal end of the tendons. This movement of the tendon 202-208 produces finger 65-68 flexion. The pulleys 230-238 prevent the flexor tendons 202-208 from bowstringing or moving away from the bone with finger 65-68 flexion. If the pulleys 230-238 are damaged and no longer function, the tendons 202-208 may bowstring with a resultant significant loss of finger motion as well as grip strength. As such, pulleys 230-238, especially the A2 pulley 232 and the A4 pulley 236, are very important and must be preserved and protected as much as possible. As shown in FIG. 5, protective padding for each finger 65-68 is placed in an anatomically designed fashion over the A2 and A4 pulley regions. When the A2 and A4 pulleys 232 and 236 are preserved, adequate finger 65-68 motion and grip strength is maintained.
Referring now to FIGS. 3 and 4, an exemplary golf glove 100 is shown for a left human hand 10. Even though the glove 100 is shown for a left hand, it is realized that a glove for a right hand utilizes symmetrical placement of elements, materials, and the like as those shown for a left hand glove 100. In FIG. 3 is shown a dorsal side 101 of a golf glove 100 to cover a human hand 10 and FIG. 4 shows the palmar side 103 of the same glove. The glove 100 also includes finger stalls 102, 104, 106 and 108 to receive fingers 65, 66, 67 and 68, respectively therein. A thumb stall 110 is also provided to receive the thumb 64 therein.
The glove 100 is provided with a dorsal side covering or panel 112 for covering the back side or dorsal side 101 of the hand 10, as well as the dorsal sides of the thumb stall 110 and finger stalls 102, 104, 106, and 108. The dorsal side covering or panel 112 is usually a synthetic material such as, for example, JANEC SUPER® or leather or the like. Preferably, the dorsal side 101 is also provided with an expansion zone 132 which is positioned to cover the metacarpophalangeal joints of the small finger 68, the ring finger 67 and the long finger 66 (shown in FIG. 1) and an expansion zone 134 is positioned to cover the metacarpophalangeal joint 37 of the index finger. The expansion zones 132 and 134 are usually an elastomeric material, such as, for example, 2-way SPANDEX® or LYCRA®. Expansion zones 132, 134 in the area of the metacarpophalangeal joints of the hand 10 allows flexibility or movement of the joints when in use, such as for bending the fingers to grip a golf club. Moreover, padding 136 along the inside of the thumb may also be provided for comfort and shock absorbing protection when hitting a golf ball or the like. On the dorsal side 101 of the glove is also provided a fastening device, as illustrated by the numeral 90, which may be any fastening device, such as a hook and loop fastener, which is well known in the art.
Also provided in the web area of the glove 100 between the finger stalls 102, 104, 106, and 108 are gussets 120, 122 and 124, respectively, wherein gussets 120, 122, 124 extend along the inner sides of the stalls. The gussets 120, 122 and 124 generally include expansion materials, such as LYCRA® or the like. Expansion material may also be provided to cover the proximal interphalangeal joints 47-50 and the distal interphalangeal joints 56-59 of each of the fingers 65-68 which are received within the finger stalls 102, 104, 106 and 108. The elastomeric material disposed to cover the proximal interphalangeal joint 48 of the long finger 66 is identified by the numeral 142 whereas the elastomeric material to cover the proximal interphalangeal joint 49 of the ring finger 67 is identified by the numeral 146 and the elastomeric material for covering the proximal interphalangeal joint 50 of the small finger 68 is identified by the numeral 150. Similarly, elastomeric material 140 covers the distal interphalangeal joint 57 (FIG. 1) of the long finger 66, elastomeric material 144 covers the distal interphalangeal joint 58 (FIG. 1) of the ring finger 67 and the elastomeric material 148 covers the distal interphalangeal joint 59 (FIG. 1) of the small finger 68. The addition of the elastomeric materials at the aforementioned joints improves the flexibility of the fingers at these joints when gripping a golf club or the like. The golf glove 100 may also be provided with an elastomeric material, identified by the numeral 116, which extends along the index finger over the proximal interphalangeal joint 47 and the distal interphalangeal joint 56 of the index finger 65.
Referring now to FIG. 4, the palmar side of the glove is provided with a palmar side panel 114 which covers the palm side of a hand 10 as well as the finger elements to be received within the finger stalls 102, 104, 106 and 108, and the thumb stall 110. The palmar side 103 of the glove 100 may also include a shock absorbing pad 138 which extends across preselected portions of the palm area of the glove.
As best shown in FIG. 5, shock absorbing pads 154, 158, 162 and 166 are provided to protect and overlie the A2 pulleys 232 of the fingers 68, 67, 66 and 65. And, shock absorbing pads 152, 156, 160 and 164 are provided to protect and overlie the A4 pulleys 236 of the fingers 68, 67, 66 and 65. The shock absorbing pads 154, 158, 162, 166 covering the A2 pulleys of the proximal phalanxes 45, 44, 43 and 42 of the finger 68, 67, 66 and 65 terminate proximal to the proximal interphalangeal joints of the fingers. Moreover, the shock absorbing pads 152, 156, 160 and 164 covering the A4 pulleys are disposed between the proximal interphalangeal joint and the distal interphalangeal joints of the fingers with the proximal interphalangeal joints and the distal interphalangeal joints of the fingers being absent of shock absorbing padding.
Gussets 120, 122 and 124 are disposed between the webs of the finger stalls 102, 104, 106 and 108 extend along the proximal phalanxes 42, 43, 44 and 45 and the middle phalanxes 52, 53, 54 and 55 with a terminating end between the proximal interphalangeal joints and the distal interphalangeal joints. And, as best shown in FIG. 6, the gusset 120 has a terminating end 180 along the middle phalanx 52 proximal to the shock absorbing pad 164. FIG. 6 shows the sectional view illustrating the terminating end of the gusset 120 along the inside of the index finger stall 102 and, the terminating end of the gussets along the other finger stalls 104, 106 and 108 terminate at substantially the same location. That is, the gussets extend along the phalanxes of each of the fingers terminating between the proximal interphalangeal joints and the distal interphalangeal joints. Moreover, the gussets 120, 122 and 124 terminate proximal to the A4 pulleys thereby allowing the glove to expand at the proximal interphalangeal joints providing for a snug fit and eliminate play of the fingers within the glove at the distal end of the fingers. Furthermore, as best illustrated in FIG. 6, by the positioning of the gusset 120 and the pad 164, the pad 164 wraps around the A4 pulley of the middle phalanx and fills in the “valley” between the proximal interphalangeal joint and the distal interphalangeal joints of the index finger, which assists in elimination of play at the distal end of the finger when holding a golf club or the like. As noted previously, even though only the gusset of the index finger has been shown in FIG. 6, it is realized that the gussets in the webs between the other finger stalls terminates along the middle phalanxes at substantially the same point and in combination with the shock absorbing pads 152, 156, and 160 also eliminates play in the other fingers when in a bent and use condition.
The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom for the modifications will become obvious for those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention and scope of the appended claims.
