Abstract: A framework is provided for a tent canopy which is capable of being erected and collapsed quickly and simply. A cart is able to support the tent framework during erecting and collapsing and is used for transporting between erection sites. The framework has a center post which is pivotally attached to four roof beams which are oriented at 90 degree increments. Each roof beam is pivotally attached to a leg and each leg to two side bars, which side bars are linearly connectable to a mating side bar mounted on an adjacent leg. Each leg pivots to a vertical orientation and rests on the ground. The framework uses a cord and pulley apparatus for collapsing the cloth canopy which covers the framework.

Abstract: A passive exercising apparatus comprises a first stationary horizontal platform connected to a second platform forming a lengthwise extension of the first platform and connected thereto for relatively pivotal or rotative movement. A drive mechanism is supported below the second platform and includes slotted lever arms and adjustable linkages enabling the second platform to be selectively pivoted up-and-down or about its central longitudinal axis so as to vary the type of exercise obtained. The second platform is capable of simultaneous pivoting and twisting motion.
