Abstract: A picnic table including a flat table section and four equally arcuately spaced support assemblies. Each support assembly has interconnected detachable elements. There is a lower seat base shaped for engaging a generally horizontal surface. Upwardly extending seat leg members are secured to each end of the seat base. A secondary leg member is fixed at its lower end to the inside of the seat base and its upper end fixed to the underside of the table. A pair of parallel wing members is arranged above its seat base, one each being fixed to the secondary leg. An angle brace is fixed between the inner section of the wing member and has its upper end fixed to the underside of the table. A top brace is fixed at one end to the wing member with the other end fixed to wing member of an adjacent support assembly. A flat seat assembly is fixed to the upper outer section of the wing members and to the upper ends of seat legs.

Abstract: A corner joint for locking in place the upright and horizontal rail members of a modular assembly is disclosed. The rail members are interconnected to form an open frame defining box-like modules for supporting shelving, side wall members, doors, and such like components. The corner joint positively locks the rail members in place and includes similarly shaped forks formed at the end sections of the horizontal rail members and a fork formed at an end section of the upright rail member. The tynes of the forks of the horizontal rail members are provided with slots on the opposite side faces thereof. The tynes of the forks of one horizontal rail member snugly and securely receive in the slots thereof the inside surfaces of a mating fork of another horizontal member. The inside surfaces of the tynes of the upright member are snugly and securely received in the slots of the tynes of the one horizontal rail member.
