The invention consists only in the fact that a double-armed lever in a slot-shaped recess trained bolt lock is used, the arm provided with a shoulder in the closed position of the bolt can be grasped by means of a spring behind a shoulder of the guide sleeve and by the pressure of the Key bit can be pivoted against the other arm from its locked position.

In a further embodiment of the invention, the key guide sleeve has a at its inner end Cutout into which the rear part of the bolt penetrating the sleeve enters.

A particularly advantageous embodiment of the invention is seen in the fact that all parts of the lock are made of plastic and are glued into appropriately arranged pipe holes.

Although it is known for the production of lock parts, such as housing, bolts, latches, etc., plastic too use. The training according to the invention is particularly suitable, however, mortise locks in all Manufacture parts made of plastic and assemble in the shortest possible time without screws, rivets, hooks or the like.

The unchangeable position of both lock parts to each other is simply due to the material of the part in the the lock is inserted, secured.

Key guide sleeve 1 and bolt guide sleeve 2

so are rotated by 90 ° against each other in corresponding Glued holes in the door 12. The key guide sleeve 1 is at the inner end with a cutout 16 provided so that the key bit end protrudes from the sleeve 1 on this part. The axes of the two Sleeves 1 and 2 are offset from one another in such a way that the rear part 15 of the bolt 3 is in the cutout 16 of the key guide sleeve 1 can occur. The key 8 is in a known manner by at the Sleeve 1 molded securing hoop 7 guided on its beard edges.

In a slot-shaped recess9 of the bolt3 the fuse 4 (locking member) is inserted, which is designed as a double lever 4 ', 4 ". It is by a Spring 5 held in place. If the locking bolt 3 through the beard of the key 8 to the outside shifted, so a lug 10 of the securing arm 4 'jumps behind a Änsatznase 11, which is inside the bolt guide sleeve 2 is located and secures (Fig. 4). If the bolt 3 is replaced by the key bit 8 fetched back, the beard only releases the security by pushing up the arm 4 ″, whereby the approach 10 released from the heel 11 and the latch 3 can be withdrawn (Fig. 6).

To install the lock, the

4-5 closing door 12 with the help of a mandrel template In the middle for the bores for gluing the bolt guide sleeve 2 and the key guide sleeve 1 like this determined that after gluing the two sleeves, the beard of the key 8 through its guide sleeve 1 engages through into the locking recess of the bolt 3.

With the help of a small centering tip 13 attached to the front of the bolt 3, it is also dabbed Color and advancement of the bolt 3 on the cabinet
