Abstract

This invention comprises a paraplegic bed having three portions, a foot portion, a body portion or seat portion, and a back and head portion; the portions are provided with means for maintaining all three portions in coplanar alignment, and changing the angle of the plane, and means are provided for changing the plane of each portion with respect to any of the others portions; and means are provided for selectively changing the seat portion both longitudinally and transversely with respect to the foot portion and back portion; said means for changing positions and relationship of parts is preferably electric push button actuated.

Claims

1. A paraplegic bed comprising a base, a plurality of bed positions, pivotal means connected adjacent bed portions, planar guideways supporting said bed portions on said base, a second guideway having terminal portions thereof substantially parallel and in different planes, an angularly disposed central portion connecting the terminal portions of said second guideway, a rack member extending the length of said second guideway and supported thereby, a pinion gear connected with one terminal bed portion and operably engaging said rack, and means selectively moving one bed portion with respect to the other bed portions and moving all bed portions simultaneously.

2. The device of claim 1 in which said means selectively moving one bed portion is electric motor driven means.

3. The device of claim 2 together with a pressure switch for actuating said electric motor driven means and releasing contact upon release of pressure.

4. The device of claim 1 together with cam actuated synchronized means to move all bed portions simultaneously.

5. A paraplegic bed comprising a substantially horizontal rectangular frame, spaced parallel longitudinal guideways supported by said frame, the terminal ends of said guideways being in different horizontal planes, an angularly disposed intermediate guideways portions connecting said terminal ends, spaced parallel substantially vertical guideways aligned with the lower terminal ends of said horizontal guideways, a plurality of pivotally connected mattress bed frames, mattress plates mounted in said mattress bed frames and supporting mattress portions, electric motor actuated means for moving one mattress bed frame on said guideways with respect to the other mattress bed frames, electrically controlled means for synchronous movement of said bed frames, electrically controlled means for moving one said mattress plates, control means for selectively actuating said electrically controlled means.

6. The device of claim 5 in which the electrically controlled means for synchronous movement is cooperating cam switches.

7. A paraplegic bed comprising a substantially horizontal rectangular frame, spaced parallel longitudinal guideways supported by said frame, the terminal ends of said guideways being in different horizontal planes, an angularly disposed intermediate guideway portions connecting said terminal ends, spaced parallel substantially vertical guideways aligned with the lower terminal ends of said horizontal guideways, three pivotally connected mattress bed frames, mattress plates mounted in said mattress bed frames and supporting mattress portions, electric motor actuated means for moving one mattress bed frame on said guideways with respect to the other mattress bed frames, means moving the central bed frame with respect to the terminal end bed frames when substantially perpendicular thereto, electrically controlled means for synchronous movement of said bed frames, electrically controlled means for moving the intermediate mattress plate, pressure actuated control means for selectively actuating said electrically controlled means.
