Lock cylinder for cylinder locks

The subject of the Neuening is a lock cylinder and in particular the design of the key introduction of the same.

So far only the introduction have been sending the keys beveled by cylinder locks in order to be able to insert them better into the slot of the lock cylinder. The surfaces of the guide slide remained for manufacturing reasons angular. Practice has shown that this is not enough.

Damage to the lock cylinder occurs again and again due to improper or forceful insertion of the canted O This risk exists

especially im. ',' inter, when ice is added to the dirt.

The .New suggests that the insertion slot of the Execute locking cylinder with inclined surfaces and adapt the key accordingly and thus the effect ^ iner To achieve self-centering.

The firing is shown in the drawing, for example, which showed a sectional view of the key insertion of a cylinder lock with an inserted key

In addition to the usual bevel 2, the key 1 has an inclined projection 3 which corresponds to the attachments 4 of the slot 5 in the lock cylinder 6. The slot 5 runs out into the lead-in bevel 8 via radii 7.

This means that key 1, when introducing the Slot 5 of the lock cylinder 6 automatically centered so that it arrives in the optimal r, in-feed direction.

The angle of the contact surfaces 4 · can be between 3o and 5o ° to the longitudinal axis of the Schioß "

The invention is not limited to that illustrated and described
