Constant tension traction device

摘要

A compact traction device includes a housing and a plurality of constant tension spring units disposed within the housing. Each constant tension spring unit includes a cable which extends from the unit through an opening in the housing. As the cable is pulled out from the housing, a substantially constant tension is developed on the cable. Hook elements are coupled to the end of each cable to enable attaching the cable to a ring or other connecting structure which, in turn, would be attached to some part of the body of a person utilizing the traction device. A brake device is included in the housing for each constant tension spring unit to inhibit the rapid retraction into the housing of the cables when the cables are released. A clamp is mounted on the exterior of the housing to enable attaching the traction device to a support frame. The clamp allows positioning of the device to have almost any orientation.
