<p>The device has directly supported supporting levers (3, 4) pivotable around an assigned pivotal axis from a non-use position into an operating position. The supporting levers are held in the operating position by releasable fixing units opposite to a loading direction, where the fixing units are formed by projections (12-14) and recesses (15-17). The fixing units fix the supporting levers in the operating position in a form-fitting and force-fitting manner opposite to a wall region, where the supporting levers are pivotally connected with objects (1) around axes (8, 9), and form four joints.</p> |
