1. A multiple position and use bed, comprising:
- (a) a ground support frame having a vertically disposed first support comprising a universal joint;
(b) first and second vertically disposed motion means operably connected to said ground supported frame, each of said motion means has a vertically movable upper portion;
(c) a support frame operably connected to said universal joint and to said first motion means upper portion so that movement of said first motion means upper portion causes said support frame to pivot about said universal joint;
(d) a mattress frame carried by said support frame and operably connected to said second motion means upper portion, said mattress frame comprises at least first and second portions and said second portion is pivotal with said first motion means upper portion and said first portion is slidably associated with said support frame;
(e) third motion means operably connected to said support frame and including a movable end portion operably connected with said mattress frame first portion for displacing said first portion toward and away from said second portion; and

Abstract
The invention concerns a bed with adjustable position, which permits tilting in all positions, which can be lowered and lifted, bent in the knee and back parts, which can be swinged and moved stepwise, in which the patient can be X-rayed, etc. The bed has a support 1 of the bed, on which is fixed a vertical support 2, which carries a horizontal support 6. In the support 2 is provided a Cardan joint 4, which permits the tilting of the bed. A system of hydraulic cylinders 9, 15, 17 and 21 permits the tilting and the moving of the reclined part of the bed, and the joints 8,14 permit the bending of the reclining part of the bed.

10. A multiple position bed system, comprising:
-
(a) a ground supported longitudinally extending frame; (b) a first vertical support secured centrally to said ground supported frame and extending vertically therefrom, said first support includes a universal joint at the upper end thereof; (c) first and second cylinder and piston assemblies secured to said frame and extending vertically therefrom, the cylinders thereof are pivotally secured to said frame and the pistons thereof extend upwardly therefrom; (d) a support frame operably connected to said universal joint and to said firt cylinder and piston assembly piston so that extension and retraction of said first cylinder and piston assembly piston causes pivoting of said support frame about said universal joint; (e) a mattress frame carried by said support frame comprises first and second sections, said first section is operably connected to said second cylinder and piston assembly piston so that extension and retraction thereof causes pivoting of said first section and said second section is slidably associated with said support frame; and
,(f) a third cylinder and piston assembly has the cylinder thereof operably connected to said support frame and the piston thereof operably connected to said second section so that extension and retraction of the piston thereof causes said second section to be displaced toward and away from said first section. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
