Abstract:
An ergonomic hand exerciser which comprises: a modified elongated handgrip for being held in a hand of a user, which handgrip when disposed generally upright and gripped with the thumb of the user's hand prevents pronation of the first metacarpal and the thumb, and which grip comprises:a) an elongated base having a central longitudinal axis and upper and lower opposed ends, and a series of generally transversely extending finger receiving grooves, each of which extends partially around said base, said grooves being spaced apart longitudinally on said base, the circumference of said base increasing upwardly from the lowermost groove to the uppermost groove, the base's reduced circumference allowing greater contraction of the small finger of the gripping hand at a joint between the phalanges and metacarpals, than the contraction of the comparable joints of the other three fingers of the gripping hand, on said base and b) a thumb support adjacent to said upper end of said base, said thumb support extending generally transverse to the axis of said base to one side of the axis having a slightly arcuate surface so as to position and support the thumb of the gripping hand in a bent position to one side of the axis with a bend in both joints of the thumb, wherein said handgrip has opposed upper and lower ends, and a throughbore is generally vertically disposed between said upper and lower ends, and wherein a member selected from the group consisting of a section of nylon webbing of a finite length and a section of elastic tubing of a finite length is disposed through said handgrip, each such section being greater than the elongation of said handgrip and having a first end and a second ends, wherein the generally vertical throughbore is disposed at an angle between 80 and 86 degrees, and further wherein the first end of said section is connected to the second end of said section to form an endless loop, the connected area being disposed up into the throughbore out of sight.
