<p>The invention relates to a locking apparatus for an insert (6), in particular for an insert of an electrical and/or electronic and/or optical switchgear cabinet, which insert is displaceably mounted in a guide (4, 5) having a plurality of latching-in openings (18), wherein the locking apparatus can be operated by means of a pushbutton (8) or slide which is accessible from the outside. According to the invention, a locking apparatus of this kind is characterized in that a locking element (29) is arranged on the insert (6), which locking element is operatively connected to the pushbutton (8) by means of a coupling element (20) and is mounted on the insert (6) such that it can be displaced along a first displacement direction (Y) which runs substantially perpendicular to an insertion direction (Z), and which can engage in a locking manner with stationary latching-in openings (18) in different locking positions in the event of displacement of the insert (6) along the insertion direction (Z). The locking apparatus is also characterized in that the first locking element (29) is mounted in an unlocking slide (27) such that it can be displaced along the displacement direction (Y), which unlocking slide (27) is mounted on the insert (6), for its part, along a second displacement direction (X) which runs perpendicular to the insertion direction (Z) and perpendicular to the first displacement direction (Y). In this case, the locking element (29) is moved out of locking engagement when the pushbutton (8) or slide is operated, and the locking element (29) is released again by means of stationary displacement elements (16), which are provided on the guide (4, 5) and move the unlocking slide (27) along the second displacement direction (X), when the pushbutton (8) or slide is operated, so that the locking element (29) latches into the next latching-in opening (18) when the next locking position is reached as the insert (6) is displaced along the insertion direction (Z).</p> |
