ABSTRACT:
A vertically-displaceable bed platform suspended from a ceiling having a platform with two forward and two rearward engagement regions, and four pulley members each disposed an equal vertical distance from the engagement regions such that two correspond with the forward regions and two with the rearward regions. Four cables are each connected to one of the engagement regions, with a first pair of cables connected to the forward region about the corresponding forward pulleys and joining the corresponding rearward pulleys, and a second pair of cables connected to the rearward regions about the rearward pulleys to join with the first pair of cables. The joined pairs of cables are attached to a counterweight, such that downward motion of the counterweight causes an equal reduction in the four vertical distances and retraction of the platform in the direction of the ceiling to a fully retracted position. Upward motion of the counterweight lowers the platform to a fully vertically extended position by extending the cables an equal distance. A pair of transverse mounted telescoping brace members traverse the distance from the a respective forward region of engagement to the corresponding rearward pulleys, and a pair of crossed telescoping brace members are attached to the rearward portions of the platform to the corresponding rearward pulley members.
