Abstract

This invention relates to folding beds and aims at correcting certain shortcomings of all other folding beds. The invention contains the mechanism of a Space-saving Folding Bed the legs of which at both ends automatically unfold when the bed is unfolded for use, and also automatically fold onto the frame when the bed is folded up.

Claims

1. In a space saving folding bed having a middle frame section supported by a plurality of generally U-shaped rotatable legs, each of said legs comprised of a horizontal portion with generally vertical extending portions pivotally connected to each end of said horizontal portion, said extending portion terminating in an upper end, said bed having frame end portions movable between a horizontal and vertical position, each of said end portions being pivotally connected to said middle frame section, said improvement comprising;

spring means for biasing each of said vertically extending portions of said rotatable legs, towards each other in said horizontal and vertical positions; and

connecting means for allowing a slidable connection, in a direction parallel to said frame end portions, between said upper end of said U-shaped legs and said frame end portion and for permitting said frame end portion and said middle frame section to be slidably lowered to said horizontal portion of said generally U-shaped legs when said frame end portions are in a near vertical position.

2. The apparatus in claim 1, wherein said connecting means comprises:

an extending pin located on the upper end of each of said U-shaped legs; and

slot means for defining an elongated aperture along each of said frame end portions, said extending pin cooperating with said slot means permitting movement parallel to said frame end portion.

3. The apparatus of claim 1, wherein said space saving folding bed further comprises leg means for supporting said frame end portions, said improvement further comprising retracting means, responsive to said vertically extending portion of said U-shaped legs, for maintaining said leg means in a vertical position when said frame end portions are in said vertical position.

4. The apparatus of claim 2, wherein said slot means further comprises a detent means for holding said extending pin against travel along said slot means when said frame end portions are in said horizontal position.

5. The apparatus of claim 3, wherein said retracting means comprises:

an angular extension fixably connected at one end to said leg means; and

an extension rod pivotally connected at one end to said other end of said angular extension, the other end of said extension rod pivotally connected to said vertical extending portion of said U-shaped legs.
