Definitions
- the invention relates to a cylinder lock with a cylinder housing and a cylinder core rotatable therein, which has a key channel for receiving a flat key, the key bit of which can be scanned by core pins, the core pins being displaceable in core pin bores within the cylinder core and spring-loaded in the direction of the key bit, and wherein the position of the Core pins can be scanned by at least one locking element which is spring-loaded in the direction of the cylinder housing.
- Cylinder locks with split pin tumblers have been known for a long time.
- the housing pin sits in a housing pin bore of the cylinder housing and the core pin aligned therewith sits in a core pin bore.
- the pin tumblers are brought into such a position that the divisions of the pin tumblers lie in the plane of rotation between the cylinder core and the cylinder housing, so that the cylinder core can be rotated.
- the aim of the present invention is a cylinder lock, the cylinder core of which accommodates all the locking elements, so that in particular the housing pin and the associated pin springs in the housing are eliminated.
- the number of components should be low.
- the lock should be designed so that conventional keys can be used, such as those used for the known locks with shared tumbler pins. This should enable retrofitting within existing locking systems with new locks.
- a flat key is to be provided for such cylinder locks, which has high numbers of variations and locking security.
- Fig.l is a section across an embodiment of the cylinder lock according to the invention.
- FIGS. 2 to 4 show a core pin with a guide body in mutually assigned cracks.
- the Fig. 5 shows a broken view of the cylinder core with a cut cylinder housing. 6 shows a section through a variant of the invention according to line VI-VI in FIG. 1, FIG. 7 illustrates an example of the flat key according to the invention in side view and FIG. 8 shows a variation scheme for the flat key in section.
- the cylinder core 2 is rotatably mounted in the cylinder housing 1.
- the rotation takes place along the cylindrical rotary plane 3.
- the key 5 sits in the key channel 4 in the form of a flat key, the key bit 6 of which has the known key notches.
- Both the key channel 4 with the key 5 and the core pin bore 8 are located in the central longitudinal plane 7 of the lock.
- the core pin 9 sits in the core pin bore 8 and is controlled in its position by the key notches of the key bit 6.
- a guide channel 10 is arranged in the cylinder core 2, which extends through the cylinder core.
- a guide body 11 is arranged in the guide channel 10 and sits laterally on the core pin 9.
- the guide body 11 has a release groove 13 on its flank 12 facing away from the key channel.
- a receiving tab 14, which engages a compression spring 15, is seated at the upper end of the guide body 11.
- the locking element 17 has at its inner end opposite each guide body 11 a sensing pin 21 which is dimensionally such that it can be inserted into the release groove 13.
- the cylinder lock works as follows:
- the core pin 9 When the key 5 is inserted, the core pin 9 is pressed downward into the assigned position by the key bit 6 against the pressure of the spring 15. The guide body 11 is also moved, with the correct key the release groove 13 coming into the position shown, so that it is opposite the locking lug 20 of the locking element 17.
- the locking element with its locking lug 20 can thus be pressed out of the locking recess 19, the scanning pin 21 being pushed into the release groove 13.
- the cylinder core can thus be freely rotated.
- the core pins 9 and the guide body 11 are arranged several times, they must all assume the position mentioned so that the locking element 17 can move into the release position.
- the core pin 9 and the guide body 11 connected to it assume a different position, so that the sensing pin 21 abuts the flank 12 of the guide body, whereby the lock is blocked.
- the cylinder housing 1 has an annular groove 22, which is open to the cylinder core 2.
- the width of the annular groove 22 speaks the width of the guide body or is larger.
- the respective ends of the guide body 11 and the core pin 9 are exposed by the annular groove 22, which on the one hand increases the stroke and on the other hand both components can be made longer, so that the guidance in the guide channel and in the core pin bore 8 is improved.
- the upper end of the guide body 11 engages in the annular groove 22 when no key is inserted, thereby providing protection against the core being pulled off.
- the cylinder core can therefore not be broken open with the known drawing method.
- the key 5 can correspond to any suitable conventional flat key, as is customary for split tumbler pins.
- it has longitudinal profile grooves 23 and lateral profile recesses 24, which can be scanned in a known manner by additional scanning elements 25 and offer additional variation possibilities, as will be explained in more detail later.
- the core pin 9 has a substantially circular cross section.
- the guide body 11 has a rectangular cross section.
- the scanning end 26 of the core pin 9 is saddle-shaped in order to facilitate the insertion of the key.
- the guide body 11 can also have a plurality of release grooves 13, as is required for locking systems.
- the possible positions of the release slots are indicated, for example, by dash-dotted lines 27. They correspond to the incision depths of the key bit notches.
- FIGS. 2 and 4 there is a web 28 with a smaller cross section between the core pin 9 and the guide body 11, which web is in a corresponding web Recess 29 of the cylinder core runs (Fig. 5).
- FIG. 5 shows a broken view of a cylinder core in a preferred embodiment.
- Core pin bores 8 and guide channels 10 are arranged in rows one behind the other.
- the spring bores 30 for receiving the compression springs 15 can also be seen.
- a slot 33 is provided between each of the guide channels 10 and the spring bores 30, through which the receiving lug 14 of the guide body 11 engages the compression spring 15.
- the guide bodies 11 in the guide channels 10 only on one side in order to keep the other side of the lock completely free, e.g. for electronic locks and signaling devices.
- the cylinder housing has the conventional housing shape with the web 32. As can be seen, there are no lock elements in this web 32.
- This web 32 can either be omitted, as is required for round cylinders, or this space can also be used for additional lock and fastening elements. be applied.
- the core pin 9, guide body 11 and the web 28 are preferably in one piece and can, for example. be produced from a metal bar profile, the cross-sectional profile of which corresponds to the outer contour of FIG.
- Fig. 6 shows an advantageous lock design (without housing) for a flat key according to Fig. 7.
- This flat key 5 corresponds to the construction as it e.g. is described and protected by EP 725 197 B1.
- the key which has longitudinal ribs and / or longitudinal grooves on the flat sides of the key, which run into the key channel in the direction of insertion of the key, additional sloping profile grooves being provided in addition to the longitudinal ribs and / or longitudinal grooves, which cut at least one of the longitudinal grooves or longitudinal ribs wherein at least one oblique profile groove is provided on each of the key flat sides and the oblique profile grooves of the two flat sides of a key or their extension line cross each other in space, the key has at least four longitudinal grooves in the incision area of the key face, each of which protrudes beyond the central longitudinal plane and in the area of the key back at least one longitudinal groove is provided, the profile groove base of which coincides with the profile groove base (s), which is preferably in the form of
- the key in FIG. 7 has on its left side of the shaft (which faces the viewer) near the key.
- selleide 34 a left rear oblique profile subgroup 35 and on the other right side of the shaft a right front oblique profile subgroup 36, which here each consist of four oblique grooves, for example.
- two locking elements 17 and two scanning elements 25.1 and 25.2 are arranged offset to one another in the lock.
- the scanning element 25.1 scans the rear left oblique profile subgroup 35 and the scanning element 25.2 scans the front right oblique profile group 36.
- the oblique profile grooves and their opposing ribs 37 on the scanning elements 25 are exaggerated here and shown in reduced numbers in order to facilitate the illustration.
- This offset arrangement of two locking elements 17 each, which scan the location of the core pins 9 and two scanning elements 25 for querying the key information in the form of the two oblique profile groups 35, 36 enables the combination of these two variation systems on a key and lock, which is considerable Offers advantages.
- the number of variations and the locking security are high, whereby all functional parts are in the cylinder core, so that so-called round cylinders can be manufactured.
- Fig. 8 the known professional l arrangement is shown in terms of its system.
- the incision area key bit
- the grooves always protrude beyond the central longitudinal plane 7, so that the profile is continuously overlapped in the incision area.
- the longitudinal profile grooves 39 and 42 are always provided with the same position and shape within a profile series, while the longitudinal profile grooves 40 and 41 are variable in their arrangement in terms of their position, as shown.
- profile groove base 43 of the oblique profile groove 44 is shown schematically in FIG. 8.
- the profile groove base 43 is arcuate, in particular in the form of a circular segment.
- the profile groove base 43 ends in the associated key flat side 45 or in the longitudinal profile groove 41. This ensures that the edge region 46 of the key spine 47 runs smoothly.
- two longitudinal profile grooves 48, 49 can be provided for variation on each key flat side.
- the profile groove base 50 of these longitudinal profile grooves coincides with the profile groove base 43 of the oblique profile grooves 44.
- the profile depth to the back of the key 47 is getting shallower.
- This measure advantageously ensures that the key maintains the necessary mechanical stability, even if a variation of the key requires a large number of cutouts, as a result of which a "jagged" profile is created in which a relatively large amount of key material is removed.
- the reference number 51 shows purely schematically scanning elements of the lock with which the presence or absence of the oblique profile grooves 44 is scanned.
- These scanning elements 51 correspond to the oblique ribs 37 of the scanning elements 25 in FIG. 6.
