Abstract
A cabinet-type bed comprises a cabinet having a pair of sidewalls upon which a bed frame is hingedly received to enable it to swing from an upright position within the cabinet into a position in which the ends form the cabinet. The pivots include a pin extending through the frame and into a housing therewithin, the pin carrying a segment with a curved edge to which a chain is anchored at one end. The chain runs over a pulley fixed in the housing and terminates in a holder attached to the wall of the housing opposite the idler by a first spring. The holder is also engageable by an end of a second spring after a certain travel to tension this second spring when the bed is swung out of the cabinet, the first spring being continuously tensioned by the chain during such swinging movement.
Claims3
A cabinet-type bed assembly which comprises:
- a cabinet formed with a pair of sidewalls flanking an opening;
- a bed frame pivotally mounted on said sidewalls and swingable relative to said cabinet between an upright position wherein said bed frame is received in said cabinet and a prone position wherein said bed frame extends from said cabinet through said opening;
- a housing received in said bed frame;
- a pivot swingably supporting said bed frame on one of said sidewalls and including a nonrotatable pin extending into said housing;
- a segment fixed on said pin in said housing and having an arcuate surface therein;
- means on said cabinet securing said pin and said segment against rotation;
- an elongated traction member in the form of a chain anchored to said segment and adapted to be taken up and paid out from said surface, said traction member having an end remote from said segment;
- a holder affixed to said end of said elongated traction member in said housing;
- At least one first tension spring anchored at one end to said holder and at another end to said housing;
- at least one second tension spring having one end engageable with said holder upon takeup of said elongated traction member by said segment to tension said second spring, said second spring having another end affixed to said housing, said housing having a pair of spaced-apart walls;
- and a pulley mounted on one of said walls, said elongated traction member extending around said pulley, said other ends of said springs being anchored to the other of said walls.
