Abstract: The present invention is for a futon frame which, in combination with a futon, will serve as a sofa or couch when in the closed position and a bed when in the open position. One embodiment of the futon frame has a base having a pair of base end serpentine slots. A back is provided which has a pair of back pivot pins which slidably engage the base end serpentine slots. A pair of back supports pivotably attach to the back and the base. A seat is pivotably attached to the back and a pair of seat supports pivotably attach to the seat and the base. Preferably, the seat is fitted with supplemental support legs which are automatically concealed within the frame during closing. In a second embodiment an additional pair of back pivot pins are provided which, in combination with an additional pair of base end serpentine slots, replace the back supports.

Abstract: The present invention is for a futon frame which, in combination with a futon, will serve as a sofa or couch when in the closed position and a bed when in the open position. The futon frame has a base having a first end with a first base end slot and a second end with a second base end slot. A back is provided which has a first back side member and a second back side member. A first back pivot pin attaches to the first back side member and a second back pivot pin attaches to the second back side member, with the first back pivot pin slidably engaging the first base end slot while the second back pivot pin slidably engages the second base end slot. Preferably, the base end slots define a serpentine path. A first back support pivotably attaches to the first back side member and the base while a second back support pivotably attaches to the second back side member and the base. A seat having a first seat side member and a second seat side member pivotally attaches to the back.

Abstract: An improved frame for a futon sofa/chair having a first base end and a second base end. The base ends have guide slots which engage guide posts, the guide posts are mounted to a back, which is pivotably attached to a seat. The improvement resides in providing backstops attached to the first base end and the second base end which further support the back of the sofa/chair when the back is upright and when the back is horizontal. In another embodiment of the invention, the frame additionally has a rear deck panel which is pivotably attached to the back and a pair of rear deck supports which are pivotably mounted to the rear deck panel and to the base ends. In a further preferred embodiment, the rear deck supports have deck segment supports which pivotably attach to the rear deck panels and base segment supports, which pivotably attach to the base. The rear deck supports and the rear base segment supports are in turn pivotably connected.

Abstract: The present invention is for a sofa bed recliner that can be simply opened into a bed or closed to form a sofa. The mechanism allows the sofa to be opened or closed while being in close proximity with a wall.The mechanism also provides for the positive locking of the back frame element to the seat frame element both in the closed and open position to assure a rigid structure in both positions.
