ROGERS, BERESKIN /A PARR CANADA Title: CONICAL WEDGE FASTENING SYSTEM Inventor: RUDOLF RIETZ The disclosure relates to a method of fastening together two members, one of which is moulded in a plastic material. One example of an application of the method is in the manufacture of furniture articles such as chairs of the type comprising a moulded plastic shell and a metal frame supporting the shell. The shell and frame are fastened together by driving a conical fastening element into a moulded post on the shell which extends through an opening in the frame. The element becomes buried in the post and causes it to "mushroom" and form a head at the outer side of the frame member. |
