Model name:
Door lock

The new rank "refers to a door lock. In the known door locks, both the profiled keyholes in the lock plates and the key insertion openings are arranged in the key plates parallel to the lock faceplate. Firstly, this arrangement of keyholes has the disadvantage that you have an auxiliary tool or the like. easily into that Insert the inside of the lock and open the lock. Second, the keyholes on top of each other form a relatively large one large unwanted opening into the interior of the room. Third allow the continuous keyholes to push through a key stuck in the lock from the outside to the inside, whereby then the introduction of an auxiliary tool into the interior of the lock is made possible.

The task of the innovation is to eliminate the listed deficiencies and without additional components in the simplest way to create a door lock, which not only makes it difficult to insert an auxiliary tool into the interior of the lock, but which also prevents a key stuck in the lock from being pierced, and the look-through opening is significantly reduced in size will.

This object is achieved according to the hiring in that between the lock plates of a door lock and the key plates in the door wood according to the diameter of the key bit circle large recesses are provided, which is shown in the key 1-sign provided key insertion hole parallel to the lock evert, on the other hand, the profiled keyholes provided in the lock plates against the key insertion holes by 90 degrees are arranged twisted.

To operate the lock, proceed as follows: that you insert the key in a conventional manner through the keyhole in the door plate. Because the keyhole in the lock plate is arranged rotated by 90 degrees, the key bit naturally hits the lock plate. Through the recess provided in the door wood it is possible to turn the key 90 degrees to the left and can then push it forwards again be introduced into the interior of the castle. The key can be withdrawn in the same way.

This design of the door lock initially has the advantage achieved that the introduction of an auxiliary tool into the interior of the lock is essential due to the offset keyholes is made more difficult. Furthermore, a key stuck in the lock cannot be pushed through because the key bit between the Lock plate lies. Due to the staggered arrangement of the keyholes, the gate part is also achieved that with keylessea Closure only a small opening in the diameter of the key shaft is available, which no greater insight permitted into the interior of the room.

In order, on the one hand, to prevent the key from being pierced by the second lock plate when the key is inserted into the interior of the lock and on the other hand with a door lock hung on the left or right for the purpose of introducing the key into the interior of the lock To have to turn the key to the left in both cases are, according to the innovation, those in both lock plates Gate-seen keyholes are arranged rotated by 180 degrees.

The subject of innovation is on the drawing in an exemplary embodiment shown, namely showj

! ig. 1 is a partial front view of the key plate attached to the door;

Pig. Fig. 2 is a partial front view of a per se known Door lock,

Pig. 3 shows a cross section along line A-B of Pig. I and

Pig. 4 shows a horizontal section along line C-D of the Pig. 3. The registration is based on a known door lock, which is built into the door 1 in a conventional manner. Between the lock plates 2 and in a known manner Key plates 3 attached to the door are provided in the door wood 1 with recesses 4, the size of which corresponds to the diameter of the key bit circle correspond. The key insertion openings 5 provided in the key plates are parallel in them arranged for the lock faceplate 6. Each profiled keyhole 7 in the lock plates 2 is against the key insertion holes arranged offset by 90 degrees, so that after the introduction of the key bit 8 in the recess 4 for the purpose of introducing the same in

the keyhole provided in the lock plate 7 of the key Must be rotated 90 degrees to the left. As in particular from Figure 2 and 3 it can be seen, the two keyholes 7 in the lock plates are offset from one another by 180 degrees, whereby on the one hand it prevents the key inserted into the lock from being pushed through. On the other hand, both with a lock attached to the right or left for the purpose of introducing the key bit into the interior of the lock after introduction of the key in the recess 4 can always be performed a left turn of the same.
