Abstract

Abstract A device for perpendicularly joining furniture panels, the device having a cylindrical housing inserted into a blind bore provided in a first furniture panel and a mounting angle secured to a second furniture panel and adapted to be inserted into a receptacle provided in the housing and extending parallel to the axis of the housing. The mounting angle has lateral protrusions for engagement with a screw threaded tightening pin adjustable in a threaded hole in the housing, the threaded hole for the tightening pin forms an acute angle with the receptacle for the mounting angle and is accessible from the same side as the receptacle. By constructing the mounting angle in the form of an L-shaped or Z-shaped angle having lateral protrustions providing engagement with screw threaded tightening pins, substantially greater tightening forces for a corner joint are produced.
