STIFFENING DEVICE FOR AN ELECTRONIC CABINET

摘要

A stiffening device for an electronics cabinet has at least two angle struts that are each formed by profile bars. The profile bars enclose an obtuse angle between them and are pivoted in the upper and lower corner regions of the cabinet frame rack. The angle struts are coupled to each other in a frictional, form-locking manner at their vertices by a tightening assembly when in a closed position. A formed fit over a large area is obtained when tightening the angle struts by attaching the profile bars of each angle strut to a door. The pivots of each angle strut are used for the pivots of the corresponding door. The tightening assembly includes a hole of radius R1 arranged at the vertex of one angle strut and a hole of radius R2 arranged at the vertex of the other angle strut. The hole dimensions are such that R2 is greater than R1. A tightening latch is arranged in both holes. The tightening latch has a first disc of radius R1 pivoted in the corresponding hole of radius R1. A second disc protrudes, in the closed door position, into the hole with the radius R2. The second disc has two circular sectors, of which one has the radius R2 and the other, the radius R3. Rotation of the tightening latch causes the angle struts to tighten against each other.
