Definitions

• the present invention relates to the field of strength training and weight lifting and, in particular, to grip assist apparatus for use therein.
• Strength training has become a widely practiced activity for both men and women. In addition to being a sport in and of itself, strength training is also utilized as a conditioning and strengthening exercise for other sports, such as football, basketball, and baseball. Furthermore, athletes who rely on agility, such as tennis players, also benefit from strength training.
• protective equipment is utilized to prevent injury to the participant.
• protective equipment is also needed, as all the joints of the body may be subjected to extreme forces.
• the wrist joint is subjected to these extreme forces any time the trainee’s hands utilize a weight bar during the course of strength training.
• FIG. 1 is a skeletal depiction of the hand.
• the cross hashed bones form the metacarpus consisting of the first 608, second 606, third 604, fourth 602, and fifth 600 metacarpals.
• the shaded portion near the wrist is the carpus 614.
• Lines 612, 610 show the rough dimensions of the deep and superficial palmar arches, respectively.
• the palm of the hand is formed skeletally by the metacarpus consisting of metacarpal bones 600-608.
• the metacarpus is the intermediate part of the hand skeleton located between phalanges, or bones of the fingers, and the carpus 614 which forms the connection to the forearm.
• the metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed.
• the peripheral metacarpals - those of the thumb 608 and little finger 600 - form the sides of the cup of the palmar gutter as they are brought together, they deepen this concavity.
• the shape of the palm over these bones is formed primarily by the radial and ulnar arteries forming the deep 612 and superficial 610 palmar arches.
• the superficial palmar arch 610 reaches its apex at about the middle of the metacarpus, while the deep palmar arch 612 reaches its apex about one quarter of the way between the carpus 614 and phalanges, over the metacarpus.
• the ulnar nerve in particular, as well as the radial and median nerves, are affected by pressure to the palm. Exercises that put a large amount of pressure on these nerves leave the weight lifter susceptible to injury and syndromes, such as carpal tunnel syndrome and Guy on’s canal syndrome.
• FIG. 2 a diagram of a human hand is provided. Overlaid are indications of approximate positions of the thumb fat pad 200, pinky fat pad 202, and metacarpal fat pad series 204. These fat pads are subcutaneous fatty deposits that effectively frame the palm. Thumb fat pad 200 is positioned below the thumb and extends down almost to the wrist. The term“thumb fat pad” as used herein is understood to be so positioned, as illustrated. Metacarpal fat pad series 204 are a series of smaller fat pads roughly covering the tops of metacarpals 600, 602, 604, 606 (as shown in FIG. 1) that together extend across the top of the palm below the fingers. The term“metacarpal fat pad series” as used herein is understood to be so positioned, as illustrated.
• Pinky fat pad 202 is positioned below the metacarpal fat pad series 204 and the pinky or little finger and, like the thumb fat pad 200, extends down almost to the wrist.
• the term“pinky fat pad” as used herein is understood to be so positioned, as illustrated.
• These pads 200, 202, 204 surround dotted area of vulnerability 206. Area of vulnerability 206 does not include fatty deposits, such as pads 200, 202, 204, and is therefore relatively unprotected compared to the rest of the palm. Comparing FIGS. 1 and 2, this area of vulnerability 206 corresponds approximately with the area defined within the lines 610, 612 corresponding to the superficial and deep palmar arches.
• area of vulnerability as used herein is understood to be so positioned between pads 200, 202, 204, and roughly corresponding to the area defined within lines 610, 612, as illustrated. It is this relatively unprotected portion of the palm that is most vulnerable to injury during weight lifting, particularly pushing exercises.
• U.S. Patent No. 5,813,950 issued to the present inventor describes a novel development in grip assist apparatuses in which the flexible gripping portion that covers the palm of the lifter is formed of a tacky non-slip material that is sewn in such a way that the lifter has free movement of his hands when he is not gripping the weight bar.
• the grip assist comprises a gripping portion that extends from the lifter’s wrist to the fingertips and covers the base of the hand and is connected to a wrist strap that is of a funnel-shaped design that provides wrist support.
• 5,813,950 is that the gripping strap must be able to free stand up in front of the hand in order to be easily wrapped around the lifting bar with the tips of the fingers on the same hand.
• the gripping portion in the above-mentioned invention can be used for both pushing and pulling exercises and protects the palm of the hand from friction.
• the present inventor has discovered that the grip assist apparatus described in U.S. Patent No. 5,813,950 has valuable application in the medical field for orthopedic rehabilitation and health-related applications. In these applications, further protection for any pushing motions is desired.
• U.S. Patent No. 5,771,901 discloses an arch support for a hand that is a plate made to conform to the palm of the hand and has support edges. Although capable of supporting the palm, the invention of this patent does not protect any other part of the hand or wrist that may be affected during strength training, nor does it provide any grip assistance as is preferable during strength training. Moreover, it is hand specific, so one must be purchased for each hand.
• U.S. Patent No. 4,374,439 discloses a bowler’s wrist support that includes a flexible body adapted to be wrapped around the hand and wrist straps to hold it in position and a pocket within which fits a pad which is positioned at the palm of the hand.
• the pad is to fill the space between the palm of the hand and the surface of the ball to provide better contact with the ball to lead to better control.
• the pad is of foam plastic material which possesses some resilience.
• the pad is shaped so as to have two relatively straight edges meeting at a rounded comer where the pad is the thickest. This part of the pad fits at the base of the heel of the hand.
• An arcuate edge of the pad extends from the end of one of the straight edges and is positioned just below the base of the fingers on the palm of the hand when the wrist support is in use. From the other end of the arcuate edge is a short straight edge that is adjacent the side of the hand, which connects to another straight edge which extends near the base of the thumb.
• this invention is ill-suited to provide palm support for weightlifting purposes.
• the pad’s flexible nature will adjust with changes in pressure, making changes in grip on a bar difficult.
• it is contoured to the palm it is hand specific. In bowling, where most bowlers use only one hand, this is not a problem, but in weightlifting, this would require that the user again determine which grip is used on which hand and prevents a pair from being used by two people.
• U.S Patent no. 8,065,749 discloses a protective sheet for the hands with a hypoallergenic adhesive.
• the rectangular sheet is folded in half with cutouts for the fingers to slide through.
• the sides of the invention are open for un-obstructive movement of the thumb.
• the invention includes a cutout at the base of the hand to prevent any creasing of the material when the hand is curved in a gripping formation.
• the invention can be worn under a glove and can be used in any activity that may cause surface blemishes to the palmar part of the palm.
• the hypoallergenic sheet protects the hand and more particularly the palmar part of the hand from skin lesions caused by friction, the invention does not protect the vulnerable part of the hand from internal injuries or from carpal tunnel syndrome.
• U.S. Patent No. 6,154,882 discloses a protection device intended for reducing the risk and effect of hand and arm injuries during heavy impact.
• the device is composed of two elements, the knuckle protector and a gripping element.
• the gripping element is located in the palmar part of the hand and the invention supports several designs. All of the designs of the U.S. Patent No. 6,154,882 gripping portion contain materials that utilize layers for bendable, slide-able movement when falling. All of the designs encourage the hand to grip around the gripping portion upon impact. All of the gripping portion designs follow the same understanding that if your hand is in a gripping position during falls i.e. a ski accident, the risk of injuries to the forearm, the wrist, the small bones of the hand or the fingers is reduced substantially. While the invention protects the user from heavy impacts caused by falling, the invention does not prevent injuries for pushing movements and assist with orthopedic therapy for building strength.
• U.S. Patent No. 4,546,495 discloses a weightlifting glove apparatus that includes a tapered wedge extending from the heel of the hand inwardly toward the inside palm for use in weightlifting when presses are used.
• the wedge of this invention is somewhat flexible so that it will curve or bend with the hand as the hand grasps the bar.
• the wedge includes a generally flat base which extends from the heel of the hand upwardly toward the palm. Extending between opposite ends of the base there is a rounded edge which defines the outer periphery of the wedge.
• the top or upper portion of the wedge is a generally smoothly continuous concave area. There is a smoothly continuous tapering convex bohom to the wedge which extends from the base outwardly toward a distal end.
• the distal end is remote from the base.
• the thickness of the wedge varies from a maximum at the base to a minimum at the distal end.
• the concave top and the convex bohom are somewhat parallel to each other, although there is a tapering toward each other from the base to the distal end, and both the concave top and the convex bohom taper towards the distal end.
• the wedge of this patent is directed toward weightlifting, it still has drawbacks. Specifically, its flexible nature will adjust with changes in pressure, making changes in grip on a bar difficult. Moreover, as it covers a relatively large area of the hand, and is contoured to the hand, it is hand specific, so one must be purchased for each hand.
• U.S. Patent No. 6,102,880 discloses a lightweight wrist brace that has a flexible base which extends along the palm and receives a stiffening member within a pocket and is capable of being worn on either a right or a left hand.
• this wrist brace would be ill-suited for use in weightlifting. Specifically, it is designed to restrain the movement of the wrist, and the ability to use a full range of wrist motion during weight lifting is preferable. Moreover, it protects only a very small portion of the hand, leaving many areas of the hand that may be affected by weight lifting exposed. Also, as it includes two hand straps that wrap around the hand and are connected to each other across the dorsal area of the hand, it may unduly restrict a gripping motion of the hand, whereas an unfettered grip is extremely important in weightlifting.
• U.S. Patent 5,620,399 discloses a gripping sleeve for tightly gripping an object by hand.
• the gripping sleeve is formed of a plate formed of a tightly gripping or clinging material, the plate being connected to a wrist band by a connecting web.
• the gripping sleeve can be put on a user’s wrist with the wrist band, so that the plate lies in the palm of his or her hand.
• the plate is, preferably, in the shape of a circle.
• this invention has its disadvantages. It provides no additional palm support beyond the plate itself. Only the narrow web covers the base of the hand, leaving much of the base of the hand exposed and prone to irritation and/or injury.
• U.S. Patent 5,581,809 to Mah discloses a protective glove having a back portion, a palmar portion, and a plurality of digital sheaths distally projecting from between the back and palmar portions for use on the hand of a wearer.
• the protective glove provides a plurality of flexible resilient pads for absorbing shock positioned on the palmar portion of the glove in spaced, non-overlapping relation to each other and in adjacent substantially non-overlapping relation to the proximal digital crease, the distal transverse palmar crease and the longitudinal thenar crease, such that the plurality of flexible resilient pads abut one another in edge-contacting relation upon flexion of the hand to form a substantially continuous, non-creased shock absorbing layer covering the metacarpal region of the hand.
• the gloves are therefore designed to absorb shock on the palm, not to avoid pressure on certain parts of the palm altogether.
• the gloves also specifically teach that the resilient pads should not cross over any of the palmar creases, but that they are specifically positioned around the various palmar creases so that when the hand is in flexion, the pads will fold into the palmar creases.
• Mah’s carpal pad 34 is an insert that is, at least softly, U-shaped. The tops of this gently U-shaped carpal pad are not disposed anywhere near the metacarpal fat pad series 204. Mah teaches away from modifying its carpal pad 34 so that its tops would reach upward to be disposed on top of the metacarpal fat pad series. Mah stresses that,“[t]he improvement of the present invention... lies in the positioning and composition of a plurality of flexible means... positioned in spaced relation adjacent to, but substantially not overlapping, the major creases of the hand.” [Emphasis added, Mah, col.
• Mah’s palmar portion has no edges because Mah discloses a glove. There is no structural cut off or edge to Mah’s palmar portion because it extends around the palm and up and between the fingers. In addition, as Mah’s glove wraps all the way around the user’s hand, it cannot include contouring on the edges on either side of the palmar portion because Mah’s glove has no such edges. Therefore there is a need for a grip assistance apparatus that may be worn on either hand; that includes a palm protection; that adequately protects the parts of the hand that are affected during weightlifting; and that does not unduly restrict the hand’s gripping motion.

• the preferred grip assist apparatus 10 includes gripping portion 12, wrist portion 28, and wrist fastener 36. It is understood that the embodiments shown are the preferred embodiments, but not all features shown are necessary for the basic embodiment of the present invention.
• Gripping portion 12 is dimensioned to cover a human hand from the fingers to below the wrist joint, without impeding the thumb’s movement. Although flexible enough to be easily wrapped around a lifting bar with only the fingers of the hand on which the grip assist apparatus 10 is worn, gripping portion 12 preferably has a rigidity so that it is self-supporting and will remain extended in front of the palm and fingers if not manipulated by the hand on which grip assist apparatus 10 is worn.
• gripping portion 12 includes finger end 18, wrist end 70, first attachment edge 72, second attachment edge 74, first side 76, and second side 78.
• Finger end 18, first side 76, and second side 78 are also labeled as first, second, and third gripping portion edges 706, 708, 710 indicating that these are edges of gripping portion 12, i.e. that gripping portion 12 does not extend further than these edges 706, 708, 710 and is not connected to other structures at these edges 706, 708, 710. It is noteworthy that any sort of glove would not include such edges because the glove, by its nature, will wrap all the way around a hand. Finger end 18 and wrist end 70 are opposite from one another at the top and bottom of gripping portion 12, respectively.
• Wrist end 70 has first wrist end flank 500 on its side toward first strap 30 and second wrist end flank 502 on its other side toward second strap 31. It is understood that first and second wrist end flanks 500, 502 denote either side of wrist end 70. “Flank” is being used in this context as a synonym for“side,” but the inventor, acting as his own lexicographer, has chosen to use“flank” here so as to avoid confusion with the word“side” used in other contexts herein.
• First and second attachment edges 72, 74 are disposed adjacent to first and second wrist end flanks 500, 502 of wrist end 70.
• First and second sides 76, 78 extend between finger end 18 and first and second attachment edges 72, 74.
• First and second sides 76, 78 each include contouring 16, which accommodate the user’s thumb. Concave contouring 16 results in a narrowing 702 in first and second sides 76, 78; a first widening 700 between narrowing 702 and finger end 18; and a second widening 704 between narrowing 702 and wrist end 70.
• first and second attachment edges 72, 74 are where first and second straps 30, 31 extend from gripping portion 12.
• gripping portion 12 includes second line of symmetry 14.
• Second line of symmetry 14 is not a structure that would be readily apparent by looking at the gripping portion 12 but, rather, is an imaginary line that runs the length of gripping portion 12.
• the symmetry of the gripping portion 12 allows the preferred grip assist apparatus 10 to be worn on either hand.
• second line of symmetry refers only to the symmetry that becomes apparent if one were to fold the gripping portion 12 along the second line of symmetry 14.
• Gripping portion 12 includes U-shaped insert 80, which is detailed in FIG. 3B. Although U-shaped insert 80 is the preferred shaped insert of the present invention, it is understood that any insert that includes a gap 104 that will be disposed on top of at least a portion of the area of vulnerability of a wearer of the grip assist apparatus 10 is sufficient for the present invention.
• U-shaped insert 80 is disposed between halves 71, 73 (shown most clearly in FIG. 4) of gripping portion 12.
• U-shaped insert 80 includes first and second U sides 82, 90, each of which include an outer U side 84, 92; an inner U side 86, 94; and a U top 88, 96.
• First and second U sides 82, 90 are connected by connecting portion 98, which has a wrist end side 100 near the wrist end 70 of gripping portion 12, and a gap side 102 near gap 104.
• the wrist end side 100 connects outer U sides 84, 92 of first and second U sides 82, 90.
• the gap side 102 connects inner U sides 86, 94 of first and second U sides 82, 90.
• Gap 104 is the space between first and second U sides 82, 90 and connecting portion 98.
• First and second U outer sides 84, 92 are contoured to follow concave contour 16 of first and second sides 76, 78 of gripping portion 12.
• First and second U sides 82, 90 and connecting portion 98 form the U-shaped insert 80 so that when U-shaped insert 80 is disposed between halves 71, 73, gripping portion 12 includes three layers of material at first and second U sides 82, 90 and connecting portion 98. At gap 104, gripping portion 12 only includes two layers of material, namely halves 71, 73.
• Gripping portion 12 includes finger end 18, which is the end of gripping portion 12 that covers the user’s fingers.
• End piece 20 is disposed at finger end 18 of the preferred gripping portion 12.
• End piece 20 is preferably stiff, but flexible, and is preferably rectangular.
• End piece 20 is disposed within gripping portion 12 by any means commonly used in the art, but preferably by holding it in place between the layers of gripping portion 12 by stitching around end piece 20 and affixing it in place using an adhesive. However, in molded embodiments of the invention, such as is discussed below with reference to FIG. 4, the end piece 20 is molded integral to the gripping portion 12.
• Wrist portion 28 securably and releasably wraps around the user’s wrist.
• Wrist portion 28 includes first and second straps 30, 31, which are both preferably rectangular in shape.
• First strap 30 has free end 34 and attachment end 32, attached to first attachment edge 72 of gripping portion 12.
• Second strap 31 has free end 35 and attachment end 33, attached to second attachment edge 74 of gripping portion 12.
• Strap attachment ends 32, 33 may be attached to attachment edges 72, 74 by any means commonly used in the art, but preferably by inserting strap attachment ends 32, 33 between the halves 71, 73 of gripping portion 12 at the attachment edges 72, 74 and affixing strap attachment ends 32, 33 there by stitching and or gluing or other adhesion.
• Straps 30, 31 are attached to gripping portion 12 at angle A, which is preferably about 120°. Angle A may be greater or less than 120°, however, depending on the user’s hand. Angle A may be customized to best fit the user’s hands and to ensure a comfortable fit on either hand.
• straps 30, 31 are not identical in the preferred embodiment, because of the symmetry of gripping portion 12, either strap 30, 31 may be attached to either attachment edge 72, 74.
• straps 30, 31 include cushioned pads 38 for the comfort of the user. Cushioned pads 38 are preferably formed of foam rubber covered by a low friction fabric. This is preferred because the fabric covering over the foam rubber allows the straps 30, 31 to slide over the cushioned pads 38 and prevents it from gripping onto the foam rubber.
• Straps 30, 31 also include a wrist fastener 36 to fasten wrist portion 28 about the user’s wrist.
• Wrist fastener 36 preferably includes a first section 42 that includes a ring 44 at the strap free end 34 of one of first strap 30.
• Wrist fastener 36 also preferably includes a second section 46 on second strap 31, which may be inserted through ring 44 to secure wrist portion 28.
• Second section 46 preferably includes a first length 48 of loop-type fastener and a second length 50 of hook-type fastener so that when second strap 31 on which second section 46 is disposed is inserted through ring 44, first length 48 and second length 50 may be joined and releasably secured.
• Gripping portion 12 is preferably made of a non-slip piece of material 40, such as chlorobutyl rubber, which provides a tacky, sticky surface to allow gripping portion 12 to adhere to the palm of the user’s hand instead of sliding around while in use.
• Material 40 includes a first flat material side 504 and a second flat material side, the second flat material side being understood to be the opposite side of side 504 and therefore facing away from the viewer.
• the piece of material 40 is non-slip on at least the side that will face out when material 40 is folded.
• Gripping portion 12 is preferably formed by adhering two layers 71, 73 of appropriately sized and shaped non-slip material together, preferably by folding over one piece of non-slip material 40 at first line of symmetry 41, and stitching the two halves 71, 73 together.
• first flat material side 504 is folded along first line of symmetry 41, both of layers 71, 73 will face out and second flat material side will face itself and not be visible.
• first flat material side 504, facing out is preferably non-slip.
• the material is a moldable material, such as urethane, molded rubber or others, that is molded into the shape of at least the non slip gripping portion 12.
• gripping portion 12 When folded along first line of symmetry 41, gripping portion 12 has a rigidity such that it is self-supporting and will remain extended in front of the palm and of the fingers to allow gripping portion 12 to be manipulated by the human hand on which grip assist apparatus 10 is worn. Despite this rigidity, gripping portion 12 is sufficiently flexible to allow itself to be easily wrapped around a lifting bar 66 using only the tip of a finger.
• gripping portion 12 is shown superimposed over a hand.
• wrist portion 28 has not been included in FIG. 5, but is understood to be present as shown in FIG. 3A.
• U-shaped insert 80 is disposed between halves 71, 73, it is outlined to indicate its position within gripping portion 12. Comparing FIGS.
• first and second U tops, 88, 96 will be disposed over at least a portion of metacarpal fat pad series 204; at least a portion of first U side 82 is disposed on top of at least a portion of pinky fat pad 202; at least a portion of second U side 90 is disposed on top of at least a portion of thumb fat pad 200; and at least a portion of connecting portion 98 is disposed on top of at least a portion of both pinky fat pad 202 and thumb fat pad 200.
• U-shaped insert 80 is disposed on top of the thumb or pinky fat pad 200, 202, as gripping portion 12, including U-shaped insert 80 is symmetrical along second line of symmetry 14. Additionally and importantly, at least a portion of gap 104 is disposed on top of at least a portion of area of vulnerability 206.
• These placements of the various parts of U-shaped insert 80 ensure that more pressure is placed on the fahier parts of the hand, namely the thumb fat pat 200, pinky fat pad 202, and metacarpal fat pad series 204. Gap 104, surrounded by the area reinforced by U-shaped insert 80, will keep bar 66 from coming into contact with area of vulnerability 206, thus eliminating pressure on this unprotected and uncushioned portion of the hand and preventing injury.
• Stitching 106 is the preferred method for securely affixing halves 71, 73 to one another. Other commonly used methods of affixation, such as gluing or other adhesive may also be used. In embodiments where gripping portion 12 is a singled molded piece, no such affixation is necessary.
• solid lines indicate lines of stitching 106. Dohed lines indicate second line of symmetry 14, the position of end piece 20, the position of U-shaped insert 80, and first and second straps 30, 31.
• Stitching 106 includes at least first outer section 108, second outer section 110, first inner section 112, second inner section 114, first top section 116, second top section 118, and gap defining section 120. As shown, it is also preferred that first and second outer sections 108, 110 extend downward and meet near wrist end 70 of gripping portion 12 and that additional stitching is included to secure straps 30, 31 to first and second attachment edges 72, 74. First and second outer sections 108, 110 follows concave contour 16 of first and second sides 76, 78 of gripping portion 12, extending up toward finger end 18 and down toward first and second attachment edges 72, 74 and wrist end 70. First outer section 108 is between first side 76 of gripping portion 12 and first U outer side 84 of U- shaped insert 80.
• first outer section 108 is stitching through only first and second halves 71, 73.
• Second outer section 110 is between second side 78 of gripping portion 12 and second U outer side 92 of U-shaped insert 80. Therefore second outer section 110 is stitching through only first and second halves 71, 73.
• First inner section 112 is inside of first U outer side 84 of U-shaped insert 80. Therefore first inner section 112 is stitching through first and second halves 71, 73, as well as U-shaped insert 80.
• Second inner section 114 is inside of second U outer side 92 of U-shaped insert 80. Therefore second inner section 114 is stitching through first and second halves 71, 73, as well as U-shaped insert 80.
• First and second top sections 116, 118 are stitching just above the tops of first and second U tops 88, 96, respectively, and are therefore stitching through only first and second halves 71, 73.
• gap defining section 120 follows first U inner side 86, gap side 102, and second U inner side 94, just within gap 104, so that gap defining section 120 is also stitching through only first and second halves 71, 73.
• stitching sections 108-120 particularly with first and second inner sections 112, 114 being through U-shaped insert 80 as well as halves 71, 73, while all other sections are through halves 71, 73 only, holds U-shaped insert 80 in place, securely holds halves 71, 73 against one another, and clearly defines gap 104.
• FIG. 7 because straps 30, 31 are attached to gripping portion 12 at angle A (shown in FIG. 3A), they form a funnel-like opening 60 when attached to one another.
• Funnel-like opening 60 serves to grab the user’s wrist in order to provide a firm support during strength training.
• Funnel-like opening 60 has a distal end 62 positioned around the base of the user’s hand and a proximal end 64 positioned around the user’s wrist. As distal end 62 is larger than proximal end 64, chafing of the base of the hand is prevented.
• the nature of funnel-like opening 60 prevents circulation from being restricted in the user’s hand while enabling grip assist apparatus 10 to be firmly attached to the user’s wrist. It is noted that positioning the funnel like opening 60 about the base of the hand is preferred when the gripping apparatus is used during pulling exercises. However, when performing pushing exercises, the funnel like opening 60 is preferably positioned about the user’s wrist and tightened to provide wrist support.
