The back support is constructed from a back brace of elastic material which carries a gel pad and an air bladder. The brace supports the pad against lower back of the user in firm engagement. The air bladder is juxtaposed and generally co-extensive with the pattern containing the gel-like material. The air bladder has three individually inflatable chambers so that the user may adjust the pressure exerted on the pad and hence the support of the lower back. The gel pad may also contain a heating e...

A camera back adapted to be fitted on the back of a camera or the like has a frame for a film container pivotally mounted in the housing of the camera back for movement between the first picture taking position and a second film discharge position. A pair of processing solution spreading rollers are rotatably mounted at the top of the frame with the nip region thereof being aligned with a discharge slot in the camera back housing when the frame is in the second position. An electric motor is mou...

There is provided a back pack having an internal frame consisting of a T-shaped stay having its vertical member centrally positioned to overlie the user's spine. A load-transmitting, flexible, one-point connector extends between the pack bag, at the lower terminus of the frame, and the central rear segment of the hip belt. Stabilizer straps are provided to limit the movement of the pack bag. The one-point flexible connector permits of universal relative movement between the hip belt and the fram...

An improved back frame for supporting a tank of compressed breathing air in a life support breathing system wherein the back frame includes a harness for securing the frame to a user's back. The improvement resides in part in the provision of inclined lateral edge rails on the frame which are spaced outwardly from the user's back at the upper portion thereof and are oriented to incline or extend inwardly toward the user's back at the lower portion thereof. A retaining strap is slidably connected...

An improved back scrubber device adapted to be removably secured to a wall. The scrubber includes a base portion including a plurality of suction devices adapted to removably secure the base portion to the wall and a cover adapted to enclose an opening on the base portion. The cover includes a porous portion which is adapted to permit the passage therethrough of a soap and water solution upon the introduction of external pressure against the cover in a direction toward the back of the base porti...

A portable back rest, composed of one planar sheet of material adapted particularly, but not exclusively, for use on stadium, or the like, bleacher or plank seats which are not provided with backs. The back rest is of unitary one piece construction and comprises a sheet of material in generally planar configuration which may be stamped or molded into the proper flat configuration for ease of transport and storage. The material from which the back rest is stamped or molded, is flexible so that it...

A back support having a plurality of individually inflatable cushions extending horizontally across a frame and arranged such that air pressure may be adjusted in individual cushions to provide selective localized support to different areas of the back. A cross brace extends between spaced end frame members to furnish a firm support for each of the individually inflatable cushions to prevent undue deformation of the cushions.

A switching arrangement including a rotatable shaft and a detent controlling position of the shaft. Mounted on the shaft are a pair of circuit element carriers, each including a plurality of similar circuit elements and having peripheral blades for use in making electrical connection with the circuit elements. Positioned alongside of the shaft are stationary clips, which are arranged relative to the shaft and the circuit element carriers such that at each position of the rotatable shaft, as cont...

A two part resilient open cell foamed plastic is joined together. A strap is fastened between the two parts and extends outward in opposite directions from the joined parts. A pair of elastic straps are also joined between the plastic parts with both of these straps extending outward in the same direction which is at 90.degree. from the first strap. The adjoining faces of the two plastic parts are joined part way around the periphery only, and are not joined on the side from which the elastic st...

A back rest suitable for use by one or more persons which is designed for easy assembly and portage. A material such as canvas is releasably secured to a pair of frames which are hingedly connected together enabling two persons to use the same rest in back-to-back position.
