Definitions
- the invention relates to a lock and key system, consisting of a key, a cylinder housing in which the cylinder core is rotatably mounted, which has an axially extending key channel for receiving the key and from Zuhaltu ⁇ gen, which cooperate with notches on the key.
- Lock and key systems of this type are generally known.
- the most common systems use flat keys that have notches on the chest that represent the mechanical coding and that interact with tumbler pins in the cylinder housing.
- These flat keys have profiles on the side surfaces, specifically in the form of grooves and / or projections running at least partially axially along the side surfaces.
- the actual locking system i.e. the tumblers are thus housed in the housing.
- the shape of the cylinder housing is then predetermined, with the round part receiving the cylinder core and the flange region adjoining it.
- This type is also known as a DIN profile cylinder.
- a lock cylinder which has ball tumblers adjustable by sectors.
- the sectors are rotated about their central axis by the inserted key and thus reach a position in which the balls can enter corresponding recesses in the sectors, so that the cylinder core can be rotated.
- a locking device is known from DE 44 37 712 A1, in which the tumblers comprise a locking pin part that can be displaced parallel to the key side surface by lateral grooves in the key and corresponding drivers on the tumbler.
- the invention has for its object to provide a lock-key system of the type mentioned in such a way that on the one hand a small space is required for the installation of the lock and on the other hand a large number of locking variants is possible.
- a lock and key system consisting of a key, a cylinder housing in which the cylinder core is rotatably mounted, which has an axially extending key channel for receiving the key and from tumblers which thereby interact with notches on the key .
- That the key has notches on at least one of its side surfaces as coding, which can be scanned transversely to the longitudinal direction of the key and parallel to the side surface.
- the cylinder core has several axially one behind the other circumferentially and radially extending part of the grooves
- a radially inwardly movable and radially outwardly pushable locking bar is provided in a longitudinal recess of the cylinder housing
- Reversible keys can also be used, but also asymmetrically designed ones
- Fig. 2 is a partial longitudinal section
- Fig. 3 partially cut the cylinder core.
- Fig. 4 is a modified version
- Fig. 5 shows an embodiment with a reversible key.
- the cylinder core 2 is rotatably arranged in the cylinder housing 1. This has a key channel 7 which, as can be seen from the figure, is arranged asymmetrically.
- grooves 5 are provided which extend over part of the circumference.
- segment-like tumblers 4 are displaceable, namely against the force of springs 6.
- the shape of the tumblers 4 is adapted to the shape of the grooves, ie they are bent according to the radius of the cylinder core and the grooves.
- the shift of the Zuhaltu ⁇ ge ⁇ 4 is determined by the notches (coding) of the key. This is located on one or both side surfaces and runs transversely to the length of the key and parallel to the respective side surface.
- a locking bar 10 interacts with the Zuroise ⁇ 4, which can be pressed radially outwards into a recess 14 in the cylinder housing under the force of a spring 11. In this state, it bridges the dividing line between the cylinder housing and the cylinder core, so that rotation of the cylinder core in the cylinder housing is not possible.
- the tumblers 4 each have a recess 13 and these recesses as a whole are aligned by the displacement of the tumblers - with the correct coding of the key - in such a way that the locking bar 10 can plunge radially inwards into it.
- This radial movement of the locking bar 10 against the force of the spring 1 1 is made possible by bevels 12 which act on corresponding bevels of the locking bar when the Zylinderker ⁇ es rotate. It is clear that any wrong coding of the key leads to a different shift of the tumblers, so that the recesses 13 are then not aligned and therefore no locking operation is possible.
- FIG 4 shows an embodiment in which the notches are arranged on the side surface so that scanning from both sides parallel to the side surface is possible.
- FIG. 5 A further variant results from FIG. 5, with a reversing key being shown here, with notches on both side surfaces of the key and on both sides in the sense of the embodiment according to FIG. 4.
