Abstract
A crutch cushion, a crutch cushion kit and crutch system that includes the crutch cushion. The crutch cushion includes a body having rear, front, right side, left side, top and bottom surfaces, and a hollow chamber proximate to the bottom surface. The top surface slopes downward from the front surface to the rear surface. The right and left side surfaces each have a substantially concave shape. The bottom surface has an oblong opening proximate to and dimensioned to be smaller than a dimension of the hollow chamber.
Claims29
A crutch cushion comprising:
- a body comprising a rear surface, a front surface, a right side surface, a left side surface, a top surface, a bottom surface, and a hollow chamber proximate to said bottom surface;
- wherein said top surface intersects said rear surface, said front surface, said right side surface and said left side surface and slopes downward from said front surface to said rear surface;
- wherein said right side surface and said left side surface each have a substantially concave shape;
- wherein said bottom surface comprises an oblong opening therethough, said oblong opening being proximate to said hollow chamber and dimensioned to be smaller than a dimension of said hollow chamber;
- wherein said body is manufactured of at least one viscoelastic material and is dimensioned such that said body will not collapse completely against a head of a crutch and will not roll over said head of said crutch when a weight is placed on said top surface of said cushion.
A kit of parts for assembly to a crutch, said kit of parts comprising:
- a crutch cushion comprising:
- a cushion body comprising a rear surface, a front surface, a right side surface, a left side surface, a top surface, a bottom surface, and a hollow chamber proximate to said bottom surface;
- wherein said top surface intersects said rear surface, said front surface, said right side surface and said left side surface and slopes downward from said front surface to said rear surface;
- wherein said right side surface and said left side surface each have a substantially concave shape;
- wherein said bottom surface comprises an oblong opening therethrough, said oblong opening being proximate to said hollow chamber and dimensioned to be smaller than a dimension of said hollow chamber;
- and
- wherein said cushion body is manufactured of at least one viscoelastic-material and is dimensioned such that said body will not collapse completely against a head of a crutch and will not roll over said head of said crutch when a weight is placed on said top surface of said cushion;
- and
- a crutch handgrip comprising:
- a handgrip body comprising a top surface, a first end, a second end, a right surface, a left surface, and bore disposed through said handgrip body from said first end to said second end;
- wherein said bore is dimensioned to allow a handgrip bar to extend through said body;
- wherein said first end and said second end each have a substantially triangular shape;
- and
- wherein said handgrip body is manufactured of at least one viscoelastic foam material.
A crutch system comprising:
- a crutch comprising:
- a crutch head comprising a front horn, a rear horn, a top surface and a bottom surface;
- at least one support leg attached to and extending from said bottom surface of said crutch head;
- and
- a hand support attached to said at least one support leg;
- a crutch cushion disposed upon said crutch head, said crutch cushion comprising:
- a cushion body comprising a rear surface, a front surface, a right side surface, a left side surface, a top surface, a bottom surface, and a hollow chamber proximate to said bottom surface within which said crutch head is disposed;
- wherein said top surface intersects said rear surface, said front surface, said right side surface and said left side surface and slopes downward from said front surface to said rear surface;
- wherein said right side surface and said left side surface each have a substantially concave shape;
- wherein said bottom surface comprises an oblong opening therethough, said oblong opening being proximate to said hollow chamber and dimensioned to be smaller than a dimension of said hollow chamber;
- and
- wherein said cushion body is manufactured of a viscoelastic material and is dimensioned such that said body will not collapse completely against said crutch head and will not roll over said crutch head when a weight is placed on said top surface of said cushion;
- and
- a crutch handgrip attached to said hand support, said crutch handgrip comprising:
- a handgrip body comprising a top surface, a first end, a second end, a right surface, a left surface, and bore disposed through said handgrip body from said first end to said second end;
- wherein said bore is dimensioned to allow a handgrip bar to extend through said body;
- wherein said first end and said second end each have a substantially triangular shape;
- and
- wherein said handgrip body is manufactured of a viscoelastic foam material.
