Dismantlable connecting element for frame support - has clamp with toothed edge in elongated opening working together with toothed sector on crank

摘要

The connecting assembly uses a clamping part designed to achieve an increased draw of the crank-operated locking action. The connecting element (2) serves to join the box section structure part (1). The connecting element (2) consists of a fork-shaped cross section with legs (21), the ends of which have a semi-circular shape (24). Both legs have a penetration (25) in which a crank mechanism (3) with seating pins (31) operates. the crank mechanism has an eccentric cam-like plate (32) which operates in the penetration (283) of the clamping part (28). The cam is fitted with teeth (33) which mesh with the teeth (273) on the edge of penetration provided in clamping part (27). A further clamping element (28) is fitted with a nose (282) on its end, while groove (281) rests against the edge of the T-shaped slot of the profile (1).
