ABSTRACT:
A connector for assembling two furniture parts such as a tabletop and an associated table leg. The connector comprises a screw provided with a head and a relatively long shaft and a bushing with outer holding means and a through hole. The bushing is pivotally mounted on a smooth part of the shaft and is axially fixed as one terminal surface thereof abuts the head of the screw and the opposite terminal surface thereof optionally abuts a locking means projecting from the shaft. One of the terminal surfaces of the bushing comprises a contact knob delimiting the turning of the bushing relative to the screw to an angle less than 350.degree. when it abuts a stop projection projecting from the screw. When a table leg and a tabletop are to be assembled the bushing is initially turned into a hole in the table leg by means of a mounting tool. Subsequently the screw is screwed into the tabletop by turning the table leg about its longitudinal axis until it abuts the tabletop and the desired tightening force has been achieved. Then the table leg can be turned backwards an angle less than 350.degree. until the desired positioning of the table leg relative to the tabletop has been obtained and without changing the tightening force therebetween. As a result a table leg of a cross section corresponding to a triangle can always be secured to a rectangular tabletop and adjusted into its correct position where the right angle of the triangle opposes the right angle of the corner of the tabletop without thereby changing the achieved tightening force between the tabletop and the table leg.
