Bed

Abstract

A bed assembly that includes a platform that would typically receive a mattress so that the platform can support a person in a lying position. The platform is supported by a post that extends downwardly from the platform to base. The base is supported by a pair of links that are pivotally attached to the base and upper pivots. The base pivots about four generally parallel transversely spaced and parallel axes to provide the platform with a rocking motion.

1 . A bed assembly including:
 a platform to support a person in a lying and/or reclined position;   a support member fixed to the platform so as to extend downwardly therefrom;   a base; and   a linkage assembly supporting the member on the base for movement about two space first pivots providing first pivot axes that are generally parallel, horizontal and transversely spaced about which the member moves to cause movement of the platform.   
     
     
         2 . The bed assembly of  claim 1  further including a motor means to cause movement of the linkage assembly and therefore cause movement of the platform. 
     
     
         3 . The bed assembly of  claim 1  further including two spaced second pivots providing second pivot axes that are generally parallel, horizontal and transversely spaced, and parallel to the first pivot axes, with the platform being supported so as to move angularly about the first and second pivot axes. 
     
     
         4 . The bed assembly of  claim 1  wherein the first pivots are upper pivots, and the second pivots lower pivots, with the first pivots being transversely spaced by a predetermined distance, with said distance being adjustable. 
     
     
         5 . The bed assembly of  claim 1 , further including an adjustment mechanism to alter said distance, the adjustment mechanism moving the first pivot in unison either toward or away from each other. 
     
     
         6 . The bed assembly of  claim 5 , wherein the adjustment mechanism includes springs that maintain the adjustment mechanism in tension. 
     
     
         7 . The bed assembly of  claim 1 , wherein the assembly includes a plurality of links, with each link extending between a respective one of the upper pivots and a respective one of the lower pivots.
