<p>A rack system for electrical equipment has a set of sub-assemblies each in the form of a flat unit, which is slid between channel guides. When the subassembly reaches its end position, it is locked against sliding in the guide, by a spindle (2) which is inserted through a hollow part (1) on the top of the subassembly. The spindle (2) is rotatable about its axis and has a cam-like projection (8) which is pressed against the hollow part (1) in its certain angular position, elastically deforming it. The elastic forces stabilise the spindle in two different angular positions, in which the subassembly is secured or not against its movement.</p> |
