Door lock with latch protection «

■ »·» »» fil- ftfth ·

The object of the innovation is a door lock with a firing sender Trap equipped with a device to block the movement of the trap when the trap is expelled,

The subject of the registration serves the following purposes:

1. as a trap arrester. The blocking device prevents this the unintentional slamming of doors, for example apartment doors, which are on the outside instead of the handle have a fixed button and from there only with one Keys can be opened via the change,

2. When the doors are closed, the blocking device prevents the latch from being pushed into the lock case added security in the event of break-ins. If the lock bolt has been overcome by the burglar, she has Still trap a bolt-like function,

The object of the innovation is in a simple execution = shape shown on the accompanying drawing. They show: FIG. 1 the latch area of a door lock - the lock cover is lifted off - with the innovation in blocking position; 2 shows a section through a door leaf, roughly along the line

II - II of Figure 1;
3 shows a blocking device in side view,

In a lock case, consisting of the lock base 1, the lock cover 2 and the cuff 3, a trap k is mounted such that it can be displaced horizontally. It is guided on the one hand through an opening 5 in the cuff 3 and on the other hand through a bolt 6 which protrudes through an elongated hole 7 in the shaft 8 of the latch k . By the arm 9 of a lock nut 10, which rests against the angular end 11 of the latch k , this is drawn into the lock case against the force of a spring. (The cushioning and other details unimportant for the explanation of the subject of the application are not shown.) The pin 13 of the handle D is mounted in the square hole 12 of the lock nut 10.

A blocking device 14, the body 15 of which has round collars 16 and 16 ', is rotatably mounted with these in round holes in the lock base 1 and lock cover 2 above the latch k. By rotating the blocking device 14, the trapezoidal nose 17 pivots into a correspondingly shaped recess 18 in the upper edge of the shaft 8 of the latch k and prevents it from being pushed into the lock case, be it when the handle D or when the door T slams shut, the pivot point locking device 14, · length and shape of the nose 17 and the position, shape and depth of the recess 18 must be coordinated so that by pressure against the slope of the head of the event k, the blocking device "\ not k can be pivoted out of their active position"

The blocking device 14 is actuated via a handle 19 which is rotatably mounted in the door plate S above the handle D with a find collar 20 and whose pin 21 engages in an opening 22 thereof running parallel to the longitudinal axis of the blocking device ik. If the handle I9 in the door plate

S is rotatably mounted, the pin 21 can have a polygonal cross-section. But it is also possible - as shown in the To provide opening 22 and the pin 21 with thread and to screw into one another.

It is also advantageous to have the blocking device 14 in its
To limit the possibility of movement (not shown), for example by means of a delimitation bar fixed in the lock base 1, it is also advantageous to make the body 15 rectangular and to apply a strong spring to the operator via the handle 19 to get the feeling of the correct positioning of the blocking device i4 convey, The opening 22 can be designed either blind-hole-like or continuous »
