Abstract
A support for reclining or sitting has two tubes extending in the longitudinal direction and filled with a liquid, transverse rods being guided on said tubes so as to be movable back and forth in the loading direction. A cushion is disposed on the transverse rods and extends over the tubes from one side of the support to the other.
Claims18
A support for reclining or sitting, said support including:
- at least two parallel, spaced apart longitudinal beams;
- at least two parallel, spaced apart tubes, each said tube being at least partially filled with a medium and being seated on a separate one of said longitudinal beams;
- a plurality of transverse rods that extend between said longitudinal beams and over said tubes;
- a substructure for limiting movement of said transverse rods, rods, said substructure including:
- a plurality of longitudinal bars, each said longitudinal bar being located adjacent a side of one of said tubes so that said longitudinal bars are located below said transverse rods, each said longitudinal bar being formed with a plurality of holes, each hole being located under a separate one of said transverse rods;
- a plurality of guide rods, each said guide rod being slidably fitted in a separate one of the holes of said longitudinal bars and each said guide rod having a head end that is attached to said transverse rod located over the hole in which said guide rod is fitted and being shaped to have a plurality of longitudinally spaced apart bores that extend laterally through said guide rod;
- and
- a pair of opposed stops attached to each said guide rod, said stops being located on opposed sides said of said longitudinal bar in which said guide rod is fitted, each said stop being positioned to abut said longitudinal bar so as to limit movement of said guide rod, wherein at least one said stop is a pin that is removably fitted in one of the bores that is formed in said guide rod;
- and
- a cushion disposed over exposed surfaces of said transverse rods.
