Definitions

• the invention relates to a sash lock for a door, in particular of control cabinets or the like, with a housing which can be fixed on the door leaf or the cabinet body, a key-operated locking cylinder arranged in the housing and a locking tongue which can be rotated between an unlocking position and a locking position.
• a locking cylinder for a security key is arranged.
• the locking cylinder is connected to a locking tongue attached on the face side such that a rotation of the security key inserted into the locking cylinder is converted into a rotation of the locking tongue between its unlocked position and its locked position.
• cam lock The disadvantage associated with such a cam lock is that the tightening torque to be applied via the lock cylinder or via the rotation of the key is not sufficiently large for rotating the locking tongue between its unlocked position and its locked position; If the door and cabinet body are under mutual tension, there is a risk that the force to be applied to twist the locking tongue will lead to the key breaking off or the locking cylinder being damaged. Furthermore, the security of the cam lock against vandalism is not sufficient; If the lock cylinder is willfully destroyed or damaged so that the appropriate key can no longer be inserted, the entire cam lock must be replaced.
• the invention is therefore based on the object of eliminating the aforementioned disadvantages in a cam lock with the features mentioned at the outset - 3 -
• the basic idea of the invention is that the lock cylinder is decoupled from the locking tongue and locked in the housing when the key is removed and can be removed from the housing when the key is inserted and in the unlocked position, and that the locking tongue held on the housing has an actuation opening for positive engagement of one in the housing channel insertable by removing the lock cylinder from the housing insertable actuation.
• the invention has the advantage that the lock cylinder only serves to secure the cam lock against unauthorized opening, but is no longer used to actuate the locking tongue.
• the entire lock cylinder can be rotated in the housing and removed from its positive connection with the housing; then a separate actuation is inserted into the housing channel, which is now free, and into the actuation opening of the - 4 -
• the locking cylinder can be reinserted into the housing channel of the housing and locked therein. If the lock cylinder is intentionally or unintentionally destroyed, the lock cylinder can be drilled out of the housing, after which the cam lock can still be actuated and only the lock cylinder then has to be replaced.
• the housing has a pin protruding into its housing channel and the lock cylinder has a groove extending over an outer circumferential section with an axial groove extension extending to the free end of the lock cylinder for engaging the Has pin.
• the lock cylinder is decoupled from the locking tongue, according to one embodiment of the invention, the
• Locking tongue in a on the housing and opposite the housing between the
• Housing can be formed on the back of the sleeve.
• a positive connection is provided according to an embodiment of the invention that the housing has an annular groove on the outside and two secant-like insertion channels are formed in the wall of the union sleeve for receiving a clip spring which can be inserted into the union sleeve and engages radially with its spring legs in the annular groove of the housing. This ensures a connection that is particularly easy to install and safe to use.
• the locking tongue in the union sleeve is also positively fixed to facilitate assembly, and it is held by the assembly of the union sleeve on the housing.
• the locking tongue has a projection which projects from the housing and engages in a recess formed in the end face of the housing and which defines the angle of rotation of the union sleeve relative to the housing.
• the sash lock consists of a housing 10 which has at one end a flange 11 bearing against a door leaf or cabinet body (not shown). In the interior of the housing extends axially a housing channel 12, in which a locking cylinder 13 is arranged, into which a key indicated by the reference numeral 26 is inserted so that the tumblers 14 have fallen into their unlocked position.
• the locking cylinder 13 In its front area lying inside the housing channel 12, the locking cylinder 13 has a groove 15 which extends radially over its circumference and merges into a groove extension 16 which extends in the axial direction up to the free front end of the locking cylinder 13.
• the housing 10 has a pin 17 which projects into its housing channel 12 and engages in the groove extension 16 or the groove 15.
• the locking tongue 19 has an actuation opening 20 located in the extension of the housing channel 12 for engaging an actuation (not shown).
• the sleeve 18 is positively connected to the housing 10, but rotatably connected with respect to the housing 10 in that two secant-like insertion channels 24 are arranged in the wall of the sleeve, to which the housing 10 has an annular groove 23 on the outside.
• a clamp spring 25 is inserted, which engages with its spring legs in the annular groove 23 of the housing 10, so that the sleeve 18 is held on the one hand in a form-fitting manner on the housing 10, but on the other hand is rotatable relative to the housing 10.
• the locking tongue 19 has a projection 21 projecting towards the front end of the housing 10, which engages in a recess 22 arranged on the end face of the housing 10, the recess extending over a partial circumference of the housing 10 and the boundary edges of the recess 22 form the stops for the rotary movement of the sleeve 18 with the locking tongue 19.
• the locking cylinder 13 can now be moved by rotation into the position in which the axial groove extension 16 is aligned with the pin 17 of the housing, so that in this position the locking cylinder 13 out of the housing channel 10 can be pulled out.
• the locking tongue 19 can thus be rotated with any force.
