Futon frame with load bearing detent apparatus
First Claim
1. A futon having a back platform coupled to a seat platform, said back platform and said seat platform having a spatial relationship defined therebetween and moving between a seating position and a bed position, said futon comprising:
- a futon frame having a first end frame and a second end frame;
a first and a second leg disposed on said first and said second end frame; and
a force spreading mortise plate disposed between said back platform and said seat platform, said force spreading plate having a detent disposed thereon to enable said spatial relationship during engagement of said seat platform and said back platform to be substantially the same as said spatial relationship after movement of said seat platform and said back platform when said futon is moved between said bed position and said seating position.

Abstract
A futon frame features the use of a cam and journal system to move and to secure the back and the seat of the futon in a desired position. The cam and journal system provide the means to move the futon from a seat position to a bed position, and also provide the support mechanism to maintain the seat and back platforms in either position without the aid of any other locking mechanism or support arms. The cam and journal system consists of strategically placed cam and journals. The seat and back move in the cams by means of journals in predefined paths.
