Definitions
- the invention relates to a rotary cylinder lock with a cylinder housing and a rotatably mounted therein, a key channel for receiving the key with at least one notch on the back of the cylinder core, which is provided on its outer surface with at least one annular groove.
- a rotary cylinder lock with a cylinder housing and a cylinder core rotatably mounted therein with a key channel for receiving a flat key is already known.
- Core pins are located in the cylinder core and housing pins in the cylinder housing are radially displaceable by spring pressure.
- the cylinder core has annular grooves on its outer surface, which can be supplemented by corresponding notches on the spine of the key. With the help of these ring grooves, a coupling of a housing pin with a core pin is brought about.
- the object of the present invention is now to provide a rotary cylinder lock of the type described in the introduction, which enables the key profile variation to be enlarged with only little additional construction effort.
- the cylinder core can only be rotated slightly until it comes into contact with the back of the key that does not match the locking pin or, in the other direction of rotation, only by one full turn until it contacts the locking pin.
- This embodiment of the invention also has the advantage that the entire length of the key spine is available for the notch, so that a large number of variations are already available in relation to the distance between the notch and the key face.
- Another variation is also in the shape of the notch, the associated ring groove, and the locking pin protruding into it. This shape can e.g. be trapezoidal, semicircular, V-shaped or the like.
- Another preferred embodiment of the invention also consists in the fact that several notches are provided on the spine of the key and an equal number of ring grooves in the cylinder core, each ring groove being assigned at least one locking pin.
- notches of different depths are provided on the spine of the key, each of which is assigned an annular groove of the same depth and at least one correspondingly long locking pin.
- the longitudinal direction of the notch on the back of the key is formed obliquely to the longitudinal direction of the key.
- a rotary cylinder lock 1 shown in Fig. 1 consists in a conventional manner of a cylinder housing 2, a cylinder core 3 with a key channel 4 for receiving a flat key 5.
- Core and cylinder pins 6 and 7 are slidably mounted in corresponding holes and are through the Pressure of coil springs 8 pressed against the key bit.
- locking pins 9 are attached to the cylinder housing 4 when the key is unlocked on both sides of the key channel 4. These are inserted into a bore of the cylinder housing 2 and protrude with their radially inner end into an annular groove 10 of the cylinder core 3.
- This annular groove 10 is slightly wider than the locking pins 9, so that an unimpeded rotational movement of the cylinder core is possible despite the above locking pins 9.
- the key 5 has a notch 12 in the area of its key back 11. The distance of this notch 12 from the key face 13 corresponds to the distance of the annular groove 10 from the stop 14 of the cylinder core 3.
- the length of the notch 12 is slightly larger than the thickness of the locking pins 9.
- the cylinder core 3 can be rotated with the help of the key 5 inserted into the key channel 4 without hindrance by the locking pins 9, since the notch 12 of the key 5 positioned in the annular groove 10 means that no stop on the locking pins 9 is possible is.
- FIG. 3 The situation in the embodiment according to FIG. 3 is different who uses a key without a notch on the back of the key.
- the back of the key 11 stops against the locking pin 9, so that further turning and opening is excluded.
- the embodiment shown in Fig. 4 clearly shows that a complete removal of the key spine 11 to avoid a stop on the locking pins 9 is not expedient, since with this solution after a half rotation of the cylinder core 3 a locking by the core and housing pins 6, 7th he follows.
- notches 12 are given in the key back 11 of the key 5 shown in FIG. 5. In a departure from this embodiment, a plurality of notches 12 of the same type can of course be provided in succession.
