Mechanical force-transmitting joining system for joining structural or sheet metal parts

Abstract

The invention relates to a mechanical force-transmitting assembly system (1) for joining structural or sheet metal parts (6,7). The assembly system comprises a first identical displaceable fitting part (2) and a second identical displaceable fitting part (3), which are configured with mutually cooperating force-transmitting wedge surfaces (4). The fitting parts (2,3) are configured to be inserted together into grooves (5) with a guiding geometry in the structural or sheet metal parts (6,7) to be joined. By a relative linear displacement movement between the fitting parts (2,3), the movement is converted via the force-transmitting wedge surfaces (4) into a controlled contracting force between the structural or sheet metal parts (6,7), whereby the parts are joined. The connection is self-locking by wedging between the mutually displaceable fitting parts (2,3).In a preferred embodiment, the fitting parts (2,3) are identical, and the grooves (5) comprise a guide geometry, for example T-shaped, which controls the relative movement of the fitting parts during assembly. The assembly system is designed to be concealed in the structural or plate components (6,7) to be assembled, with the exception of one end surface of the fitting parts. The invention enables a precise, demountable and repeatable mechanical assembly without the use of glue, screws or special tools and is particularly suitable for furniture, kitchen elements, modular structures and other structural or plate components.
