Abstract
A bed in which a rockable frame comprises two longitudinally extending members over which is tensioned an open mesh net for supporting a patient. A plurality of adjusting means are provided for adjusting the tension of the net at various spaced positions along the length of the bed to accommodate the net to the shape of a particular patient being supported. Preferably a back and head rest also comprises a net to support the patient and padded sides are provided for pivotal movement between a position extending to retain a patient on the bed and a downwardly extending out-of-the way position. The various tension adjusting means preferably engage a flexible member threaded into the longitudinal side edges of the net for spreading the transmission of the tensioning load to the net.
Claims19
In a bed comprising a base frame, a support frame carried by the base frame for pivotal movement about an axis extending longitudinally thereof, and means for adjusting the pivotal position of the support frame relative to the base frame, the support frame comprising a pair of spaced parallel longitudinal members, and a supporting web extending across between said members, the improvement that the web is a net and that a plurality of adjusting means are provided at separate locations intermediate the ends of the bed and spaced along the length of the support frame for providing a continuous adjustment to vary the tensioning of the net at different locations spaced along the length of the support frame.
A bed comprising a base frame, a support frame carried by the base frame for pivotal movement about an axis extending longitudinally thereof, means foe adjusting the pivotal position of the support frame relative to the base frame, the support frame comprising a pair of spaced parallel longitudinal members, and a supporting net extending across between said members, a plurality of adjusting means provided at separate locations spaced along the length of the support frame for varying the tensioning of the net at different locations spaced along the length of the support frame, and a head support mounted to the support frame and comprising an inverted U-shaped frame carrying netting thereacross, the bight of the U-shaped frame being pivotally and vertically adjustably mounted at one end of the support frame and the ends of the legs of the U-shaped frame being shaped to be supported by the longitudinal members at various inclinations of the head support.
In a bed comprising a base frame, a support frame carried by the base frame for pivotal movement about an axis extending longitudinally thereof, ands means for adjusting the pivotal position of the support frame relative to the base frame, the support frame comprising a pair of spaced parallel longitudinal members and a supporting web extending across between said members, the improvement that the web is a net having longitudinal sides edges and that the bed comprises a pair of flexible elongate members each engaging a respective one of said longitudinal side edges of the net, a plurality of screw adjusters provided at locations spaced lengthwise of the frame and means connecting said screw adjusters to the flexible elongate members at positions spaced longitudinally of the elongate members whereby the tension across the net is continuously variable at locations spaced lengthwise of the net by actuation of individual ones of said screw adjusters.
