ABSTRACT:
A doorway exerciser comprising a scissor-type spring-biased clamp having opposed arms for securing the exerciser above the upper doorframe and a strap adjustable in length removably secured to the clamp and extending downwardly. The strap passes downwardly into a tube having a compression spring therein, through a slotted plate at the bottom of the spring, and returns upwardly and is secured to itself. The tube is preferably of plastic and has three equally spaced ears extending therefrom witch two parallel slots in each ear. A separate strap for each ear passes upwardly through a first slot and downwardly through the other slot in each of the ears. One end of the strap is configured so as to prevent movement through the first slot. The other end of the strap is secured to an infant seat.
