A novel improvement in a crutch device allowing for the rotational movement of the arms and elbows of the user while supporting his/her weight on a pair of these crutches, by displacing the vertical support means, between the under-arm rest and the hand rest, rearward a sufficient distance. This improvement, combined with an all terrain crutch pad and easy adjustable crutch length allows an individual with severe restriction in mobility from the waist down to play active sports, such as golf, and engage in employment requiring the free movement of hands and arms while maintaining mobility of the total person.

A crutch wherein a vertical support between a shoulder rest and a hand rest is displaced rearward, being comprised of a shoulder rest means, a swing height adjustment means, a hand rest means, a vertical support means, a height adjustment means and an all terrain foot means wherein: said shoulder rest means is comprised of rigid hollow pipe which extends in a semi-circular manner, extending rearward, then makes a reverse bend to vertical adjustably communicating with a swing height adjustment means; said swing height adjustment means being comprised of a swing height adjustment rod of suitable rigid material having an outside diameter slightly less than an inside diameter of the rigid hollow pipe of the shoulder rest so that it slidably fits therein and having regularly spaced holes through it at one inch intervals along its length aligned so as to accommodate a bolt secured by a self locking nut which extends from a reinforcement collar of suitably rigid material which is fixedly attached to an end of the shoulder rest by standard weld or bonding means and an end of the swing height adjustment rod opposite to an end extending into the shoulder rest is rigidly fixed into an end of a hand rest means by standard weld or bonding means so that vertical distance between the shoulder rest and hand rest is adjustable by engaging the bolt in different holes along the length of the swing height adjustment rod; said hand rest means is comprised of rigid hollow pipe which extends vertically from the swing height adjustment then makes a reverse bend to parallel the shoulder rest a like distance, having within and near its end a semi-circular portion, and is joined by standard weld or bonding means to a vertical support means at its top; said vertical support means being comprised of rigid hollow pipe which extends vertically, and includes a height adjustment means at its lower end; said height adjustment means being comprised of a height adjustment rod of suitable rigid material having an outside diameter slightly less than the inside diameter of the pipe of the vertical support so that it slidably fits therein and having regularly spaced holes through it at one inch intervals along its length aligned so as to accommodate a spring pin set by standard means near the lower end of the vertical support so that the vertical support may be adjusted and said height adjustment rod, at its lower end, expands in diameter to larger than the outside diameter of the vertical support and forms a height adjustment rod flange attachment fork having two tongs, extending downward a sufficient length and spaced sufficiently apart so as to accommodate an attachment flange of an all terrain foot means, and having a bolt or channel pin, equipped with a spacer collar, and held in place by a standard retention nut means, extending perpendicularly through the tongs of the height adjustment rod flange attachment fork and through a hole in an attachment flange of an all terrain foot means, said hole being located on an attachment flange so that, when the bolt is installed, a top face of the attachment flange physically impinges on a crotch of the height adjustment rod flange attachment fork so that rotation of the attachment flange around the bolt is limited from 0 to 15 degrees; said all terrain foot means, being made of suitable flat rigid material, is comprised of a foot vertical support, extending from the top of an elliptically shaped inner foot vertically and having an attachment flange at its top end and being attached by standard weld means to the top of the inner foot at 15 degrees from perpendicular toward the user at a point so that the foot vertical support is positioned in a center of the elliptically shaped inner foot of the crutch, so that there is a right hand and a left hand crutch, and a shoe print means made of suitable material such as rubber or leather, being slightly larger in diameter than the elliptically shaped inner foot, equipped with slots molded into and around the top edge of the shoe print to removably accommodate the thickness of the elliptically shaped inner foot and having a suitable non-skid tread on its bottom face.
