DETAILED DESCRIPTION
(16) Referring first to
(17) 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.
(18) In the preferred embodiment of
(19) In embodiments that may be worn on either hand, 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. Although it is understood that there are at least two symmetries along second line of symmetry 14, including symmetry through the plane of gripping portion 12, it is understood that as used herein, 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. It is further understood that although first features of gripping portion 12 are indicated on the right and second features of gripping portion 12 are indicated on the left, these designations are arbitrary, as gripping portion 12 is symmetrical and all first and second features of gripping portion 12 are mirror images of the other across second line of symmetry 14.
(20) Gripping portion 12 includes U-shaped insert 80, which is detailed in
(21) 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
(22) When grip assist apparatus 10 is in use, 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.
(23) 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. Although 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. In the preferred embodiment, 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.
(24) 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.
