Connection for furniture frame parts, particularly office furniture

A furniture frame comprising first and second frame members connected to one another, said first frame member having a dowel extending outwardly thereof, said second frame member having an elongated opening therein, said dowel extending into said opening, said dowel having a pair of spaced exterior planar surfaces which are disposed on opposite sides of the longitudinal central plane of said dowel and which are inclined at angles to said longitudinal central plane of said dowel, said opening having a pair of spaced interior planar surfaces which are disposed on opposite sides of the longitudinal central plane of said opening and which are inclined at angles to said longitudinal central plane of said opening, said inclined exterior dowel surfaces being in abutment with said inclined interior surfaces of said opening respectively, the angles of inclination of said exterior dowel surfaces being slightly greater than the angles of inclination of said interior opening surfaces, and a screw member in thread engagement with said second frame member and extending into said opening at right angles to the longitudinal axis of said dowel, said screw member being positioned to engage an exterior side of said dowel and to apply a force thereto in a direction transverse to said axis of said dowel to press said inclined exterior surfaces of said dowel into forceable engagement with said differently inclined interior surfaces of said opening thereby to securely connect said first and second furniture frame members to one another.
