ABSTRACT:
The present invention relates to an orthopedic crutch that includes a pair of vertical supports which may be formed from tubular members, connected together at one end by a cross-member, which may be cushioned, forming an armpit support. The other ends of the vertical supports are bent inwardly and connected to an adjustable support leg assembly. A handgrip assembly is disposed intermediate the opposing ends of the vertical supports. The handgrip assembly includes a horizontal cross-member, rigidly secured between the vertical supports, a pair of telescoping members and a yoke assembly. One telescoping member, formed as an extending tubular member, is rigidly secured intermediate the opposing ends of the horizontal cross-member. The other telescoping member, which includes a tubular portion, formed with a slightly larger diameter to enable telescoping action between the two telescoping members, is rigidly secured to the yoke assembly which includes two depending legs. A coil spring is disposed within the telescoping members which act as a spring retainer to bias the yoke upwardly. A handgrip, which may be cushioned, is rigidly secured between the two depending legs of the yoke. By providing a movably mounted and spring biased handgrip relative to the vertical supports, the orthopedic crutch in accordance with the present invention, provides increased comfort level to the user. The depending legs of the yoke may be formed with longitudinal arcuate notches which act to guide the vertical movement of the yoke relative to the vertical supports. Additionally, the support leg assembly, armpit support, as well as the handgrip assembly, are relatively easily and quickly adjustable.
