Abstract:
1. A furniture item having user-support frames that are convertible between a seat configuration and a bed configuration and that include a first support frame anchored to a furniture-item base and a middle support frame pivotably coupled to the first support frame, the furniture item comprising: a link assembly that couples the first support frame to the furniture-item base and that includes two links positioned substantially parallel to one another; a pin that couples the link assembly to the furniture-item base, wherein the two links are spaced apart by a roller, which provides rolling support against the furniture-item based when the link assembly pivots on the first pin; a pivot mechanism that couples the link assembly to the first support frame, wherein the combination of the link assembly, the first pin, and the pivot mechanism facilitates both pivoting and lateral shifting of the first support frame relative to the furniture-item base; a cam-follower block disposed under the first support frame and the middle support frame when the first support frame and the middle support frame are in the bed configuration, which is generally horizontal; and a cam block coupled to the middle support member proximate to a junction at which the middle support frame is pivotably coupled to the first support frame,
