Plug-in lock

Abstract

The invention relates to a plug-in lock for the detachable connection of two belt ends for a climbing harness having a lock part and an insertion part, wherein the lock part has an end on the insertion side for inserting the insertion part, and an end on the belt side for fastening a belt, wherein the insertion part has a snap-in pin, which engages into a first latch mechanism in the lock part upon inserting the insertion part into the lock part such that the insertion part is secured against being pulled out of the lock part (in the direction opposite of the insertion direction in the lock part. The first latch mechanism is configured manually non-detachable, and a second manually detachable latch mechanism is arranged and configured such that the insertion part can be detached from the lock part by sliding out the same in the insertion direction.

1 . A plug-in lock for the releasable connection of two belt ends, in particular for a climbing harness, safety belt or life belt, comprising:
 a lock part; and   a plug-in part;   wherein the lock part has a plug-in end, into which the plug-in part can be plugged, and a belt end, for fastening a belt, wherein the plug-in part has a latching tongue which, when the plug-in part is plugged into the lock part in a plug-in direction, latches with a first latching mechanism in the lock part such that the plug-in part is locked in the lock part against being pulled out of the lock part counter to the plug-in direction, and wherein the plug-in direction is oriented from the plug-in end of the lock part in the direction of the belt end of the lock part, including having the first latching mechanism is designed such that it cannot be released manually once the plug-in part and lock part have been latched in, and a second, manually releasable latching mechanism is arranged in the lock part and designed such that this second latching mechanism, in a locked state, blocks the plug-in part which has been plugged into the lock part from moving relative to the lock part in the plug-in direction and, in an unlocked state, allows the plug-in part which has been plugged into the lock part to move relative to the lock part in the plug-in direction, in which case the plug-in part can be released from the lock part by being pushed out in the plug-in direction.   
     
     
         2 . The plug-in lock of  claim 1 , wherein the first latching mechanism includes at least one latching nose arranged on the latching tongue, the latching nose pivotable about a pivot pin, wherein the latching nose is forced in the direction of a locking position by an elastic pre-stressing force and can be deflected in an elastically resilient manner out of this locking position by being pivoted about the pivot pin counter to the pre-stressing force, and wherein a rigid latching hook is designed and arranged on the lock part for each latching nose such that, once the plug-in part has been plugged into the lock part, a respective latching nose interacting with an associated latching hook makes a latching connection. 
     
     
         3 . The plug-in lock of  claim 2 , wherein the latching nose includes a respective oblique surface which rises up in the direction counter to the plug-in direction. 
     
     
         4 . The plug-in lock of  claim 2 , comprising two latching noses arranged on the plug-in part and two latching hooks are arranged on the lock part, wherein the two latching hooks are designed as respective U-shaped elevations at the plug-in end of the lock part. 
     
     
         5 . The plug-in lock of  claim 4 , including a respective leg of the U-shaped elevations having a free end, wherein the legs of the U-shaped elevations with a free end are spaced apart from one another such that a spacing between these legs of the U-shaped elevations is greater than or equal to a width of the latching tongue of the plug-in part. 
     
     
         6 . The plug-in lock of  claim 1 , including the latching tongue having an elevation running parallel to the plug-in direction and the lock part having a groove running parallel to the plug-in direction, wherein the elevation and the groove are arranged and designed such that, when the plug-in part is plugged into the lock part, the elevation engages in the groove and thus guides the plug-in part relative to the lock part. 
     
     
         7 . The plug-in of  claim 1 , including having the second latching mechanism is forced in the direction of the locking position by an elastic spring pre-stressing force. 
     
     
         8 . The plug-in lock of  claim 7 , including having the second latching mechanism arranged and designed such that it can be moved manually into the unlocked state counter to the elastic spring pre-stressing force. 
     
     
         9 . The plug-in lock of  claim 3 , comprising two latching noses arranged on the plug-in part and two latching hooks arranged on the lock part, wherein the two latching hooks are designed as respective U-shaped elevations at the plug-in end of the lock part. 
     
     
         10 . The plug-in lock of  claim 9 , including a respective leg of the U-shaped elevations having a free end, wherein the legs of the U-shaped elevations with a free end are spaced apart from one another such that a spacing between these legs of the U-shaped elevations is greater than or equal to a width of the latching tongue of the plug-in part. 
     
     
         11 . The plug-in lock of  claim 2 , including the latching tongue having an elevation running parallel to the plug-in direction and the lock part having a groove running parallel to the plug-in direction, wherein the elevation and the groove are arranged and designed such that, when the plug-in part is plugged into the lock part, the elevation engages in the groove and thus guides the plug-in part relative to the lock part. 
     
     
         12 . The plug-in lock of  claim 2 , including having the second latching mechanism forced in the direction of the locking position by an elastic spring pre-stressing force. 
     
     
         13 . The plug-in lock of  claim 12 , including having the second latching mechanism arranged and designed such that it can be moved manually into the unlocked state counter to the elastic spring pre-stressing force.
