The invention relates to improvements in walking crutches that have an underarm support mounted on one end of a longitudinally extending leg. The improvements include providing the underarm support with symmetrical side portions having symmetrical concave, curved, smooth surfaces, and an upper concave, curved, smooth surface to provide less discomfort when contacting the user's side, more comfortable support of the user's underarm and greater ease of use of the crutch by compression of the underarm support between the user's side, arm and underarm. |

1. In a walking crutch comprising an underarm support mounted on one end of a longitudinally extending leg, the improvement comprising the underarm support having symmetrical side portions with symmetrical concave, and smooth surfaces curved inwards with a radius of between 4 inches and 8 inches, and an upper concave, curved, smooth surface in the direction of the top of the underarm support, having a radius of between 5 inches and 8 inches, and a wider, bulbous end transitioning from the concave curved surfaces, to provide a shape which in turn provides less discomfort when contacting the user's side, more comfortable support of the user's underarm and greater ease of use of the crutch by compression of the underarm support between the user's side, arm and underarm, and to prevent lateral movement of the crutch. |
