Abstract: A portable exercising device which can be assembled and disassembled without the use of special tools for shipping and storage is formed substantially entirely from tubular members to provide a stable support for a pair of shoulder pads and hand grips to permit the user to perform shoulder stands, the device also including an upstanding support for an elevated crossbar which serves as a leg rest when shoulder stands are performed and is also designed for attachment to a separate device, such as a treadmill or rebounding bed, in which case the crossbar serves as a hand grip for running in place or jumping. Another crossbar is attached at a lower position to support the legs when doing sit-ups on the separate device.

Abstract: A portable exercising device which can be assembled and disassembled without the use of special tools for shipping and storage and capable of permitting the user to perform a number of exercise routines, such as controlled jumping, simulated running, hand-and-shoulder stands and sit-ups. A small rebounding bed is detachably connected with an auxiliary frame, the latter having several adjustable attachements such as elevated hand grips for jumping on the rebounding bed, leg supports at a lower level for doing sit-ups, and another set of hand grips and shoulder pads for practicing hand and shoulder standing, in which case the elevated hand grips serve as foot rests. The auxiliary frame extends away from the rebounding bed to stabilize the elevated hand grips for jumping, and several of the attachments are adjustable.

Abstract: An assembly of demountable elements, each of which can be handled by one person, can be combined to convert a pickup truck body into either a camper or to provide a ladder, or boat, carrier or both. The assembly rests in the stake sockets of the truck body and can also be attached, or removed, as a unit.

Abstract: Cushioning pads are placed along the sides of a trampoline and have sufficient width to cover the ordinarily exposed springs. The sides of the trampoline frame are reinforced by an extra tube which assists in supporting the pads out of frictional contact with the springs.
