  • Patent number: 9416550
    Abstract: A work bench support bracket with first and second opposed, generally upright sockets for receiving wood members is joined to first and second telescopically interconnectible, generally horizontal sockets, respectively. First and second clamping sets are also joined to the first and second generally upright sockets, respectively. Each of the clamping sets comprises an upper releasable chimp and a fixed lower brace member. The upper releasable clamp comprises a grip pivotably attached to the upright socket, a connector extending from the grip, and a handle pivotably connected to the connector. The work bench support bracket provides for the secure attachment of the wood members and reduces the likelihood of an accidental release of the wood members.
