<p>PCT No. PCT/SE93/00241 Sec. 371 Date Sep. 22, 1994 Sec. 102(e) Date Sep. 22, 1994 PCT Filed Mar. 23, 1993 PCT Pub. No. WO93/19268 PCT Pub. Date Sep. 30, 1993Safety device to be mounted on a parallelepipedic box comprises a frame (10) constructed to encircle the box and having an insert opening (11) for the box and a blocking element (13) displaceably and pivotably mounted to the frame, the blocking element being adjustable between a blocking position and an off position to prevent in the blocking position the box inserted into the frame from being withdrawn from the frame. A spring blade (22) clamped at one end thereof in the blocking element extends in the displacement path of the blocking element to engage at the other, free end thereof behind a shoulder (25) on the frame and thus to prevent displacement of the blocking element in the blocking position, wherein positive engagement is established between the blocking element and the frame in order to prevent the blocking element from pivoting. The spring blade can be actuated by external assembly in order to release the blocking element for adjustment to the off position by displacement or pivotal movement and thus allowing the box to be withdrawn from the frame through the insert opening.</p> |
