Adjustable furniture attachment clamp

摘要

An adjustable furniture attachment clamp for attachment to the underside of a furniture item with two spaced apart arm fasteners, the clamp comprising a clamp body having oppositely disposed laterally extending forked arms, each arm having a fastener slot having a width greater than the shanks of the arm fasteners, the fastener slots including inner ends spaced apart a distance less than the arm fasteners, such that lateral and forward-to-back play is provided for adjustment of the clamp relative to the furniture item, the clamp also having a downwardly facing beam pocket including a beam capture surface for holding the right upper beam flange of a support I-beam and a cam having a binding face for pressing against the lower portion of the left upper beam flange when a cam fastener is tightened for attaching the clamp body to the I-beam.

主权项

1. An adjustable furniture attachment clamp for attaching furniture items to a wall, the furniture item having a horizontal underside, the underside having a downwardly oriented clamp recess and a pair of arm fastener holes, the clamp recess having a vertical height and opposite side edges defining a horizontal breadth, the arm fastener holes for receiving a pair of arm fasteners, the arm fastener holes separated by distance defining an arm fastener holes separation distance, each of the arm fasteners having a shank including a shank width, the adjustable furniture attachment comprising:
a clamp body having
right and left spaced apart shoulders,a horizontal top strut extending between and connecting said shoulders, anda pair of oppositely disposed horizontal arms extending laterally from said shoulders, each of said arms having a top surface and a laterally extending fastener slot having a fastener slot width greater than the shank width of each of the pair of arm fasteners, each of said fastener slots having an inner end, the inner ends of said fastener slots spaced apart by a fastener slot separation distance less than the arm fastener holes separation distance, whereby, when the arm fasteners are inserted through the fastener slots in said arms and the arm fasteners are engaged with and partially tightened in the fastener holes, said arms are loosely secured to the underside of the furniture item, lateral play is provided corresponding to the difference between said fastener slot separation distance and the arm fastener holes separation distance, and forward-to-back play is provided corresponding to the difference between the fastener slot width of each of said fastener slots and the shank width of each of the arm fasteners, thereby enabling positional adjustment of the arms relative to the furniture item before tightening the arm fasteners, and when said arm fasteners are fully tightened in said arm fastener holes said pair of arms are secured to the underside of the furniture item.
