Definitions

  • the invention relates to a cylinder lock with a cylinder housing, at least one cylinder core and pin tumblers, which are composed of housing pins and cylinder pins, wherein at least one of the pins, preferably a housing pin, is formed as a telescopic pin.
  • Cylinder locks which are intended to protect against manipulation by the so-called "picking” or in particular against the impact method, have been known for some time.
  • an adapter key is inserted in the key channel instead of the matching key.
  • the key jerky e.g. moved by a blow in the direction of insertion, so this pulse is transmitted over the key bit edges on the tumbler pins.
  • the DE 10 2006 050905 A1 For example, such an arrangement.
  • the tumbler pins consist of a housing pin and a cylindrical pin, wherein the cylinder pin is made of several parts. It consists of a cup-shaped, pointing to the ground direction tumbler spring element of the housing pin and a, pulled by a tension spring in this cup stamp.
  • the cylinder pin has at its, the housing pin end facing a recess which corresponds in size about the head of the punch.
  • the adapter key inserted into the keyhole and executed by a blow an impulse on the tumbler pins, so separate cylinder pin and housing pin from each other, but the inertia of the punch is moved into the opening of the cylinder pin, thus preventing a release position of the cylinder core relative to the housing.
  • a disadvantage of this known construction is that, when the impact is very strong or the impulse is very strong, the separation of the two pin components takes place so far that twisting of the lock is not prevented.
  • a stamp is in a cup-shaped member of the housing pin, which is pushed away by a spring thereof. If now, by a stroke, the cylinder pin separated from the housing pin, the spring moves the punch out of the cup-shaped element. With simultaneous rotation of the lock, the stamp formed as Taumelbuild wedged between the cylinder core and cylinder housing and thus blocks the lock.
  • a disadvantage of this device is that compression springs can lose elasticity over a longer service life. If the force or the stiffness of the spring changes, it can happen that the lock does not lock anymore despite the key being used. Apart from that, the construction is very complicated and very expensive and expensive due to the large number of precision parts in the production.
  • the object of the present invention is to provide a lock with Stiftzuiensen that prevents opening by the impact method, but is efficient and inexpensive to manufacture.
  • the telescopic pin has a telescopic sleeve, guided therein a telescopic punch, a compression spring and a closure.
  • Fig. 1 the lock 1 is shown with a housing 19, a cylinder core 2 with a locking nose ring 20 and a key 3.
  • key 3 an adapter key is provided in this case, as used in the impact method.
  • the pin tumblers 21 consist in this embodiment of cylindrical pins 5, housing pins 6 and tumblers 7.
  • One of the housing pins 6 is formed as a telescopic pin 8.
  • the pin tumblers When a matching key (not shown) is inserted, the pin tumblers are urged against the key bit recesses of the key by the spring force of the tumbler springs 7 and come to rest in a position where the pitches 23 between the cylinder and housing pins are exactly in line with the plane of rotation 24 between the cylinder core 2 and cylinder housing 19 are aligned. In this release position, the cylinder core 2 can be rotated relative to the cylinder housing 19.
  • the beat method is according to Fig.1 and Fig. 2 an adapter key 3 inserted in the keyway.
  • This corresponds to the structure essentially a key back, on which the pin tumblers facing side teeth are provided.
  • These prongs which have key bit control surfaces and key bit control edges analogously to the key, are pressed against the contact surfaces of the cylinder pins when the adapter key is inserted. If the adapter key is inserted into the key channel as far as the last pin tumbler, each of the tumbler pins 21 protrudes into a recess of the key bit of the adapter key 3.
  • Fig. 1 an adapter key 3 inserted in the keyway.
  • the adapter key jerky for example, moved by a blow in the direction of insertion 22, so this pulse transmits over the key bit control edges 10 on the tumbler pins.
  • Fig. 4 shows enlarged the embodiment of a telescopic pin 8 of the present invention.
  • the telescopic sleeve 11 the telescopic punch 12, the telescopic spring 13 and the closure 14, which is executed in this case as a pressed-ball.
  • the cup-shaped design of the telescopic ram 12 with the bottom 15 and the opening 16.
  • an outwardly facing shoulder 17 is provided on the telescopic ram in the region of the opening. This engages in the fully extended position of the telescopic punch or the telescopic spring 13 in the, inwardly facing shoulder of the sleeve 18 a.
  • the telescopic spring 13 is designed as a compression spring and is based on the one hand on the inside of the bottom of the telescopic ram 15 and on the other hand on the closure 14 from.
  • the telescopic pin 8 is cylindrical as well as the other tumbler pins of this embodiment.
  • Fig. 3 shows, analogous to Fig. 1 , the lock 1 with a housing 19, a cylinder core 2 with a locking nose ring 20 and a key 25.
  • a key is shown in this case, which is not suitable for locking the lock with respect to the formation of his key.
  • the pitches 23 of the Stiftzunnenen 21 are, despite fully inserted key, not in a plane aligned with the plane of rotation 24 of the cylinder core 2.
  • the telescopic pin 8 is pressed by a tumbler 7 against the dowel pin, which in turn on the key bit control surface 9 of the key 3 supported.
  • the telescopic spring 13 has a smaller force than the tumbler spring 7.
  • the telescopic ram 12 is always retracted in slow, quasi-static movements in its lowermost position, ie with compressed Teleskopfeder 13 in the telescopic sleeve 11.
  • the cylinder pin 5 facing end face of the telescopic sleeve 11 and the cylinder pin 5 facing top surface of the telescopic ram 12 form a plane.
  • a curved, stepped or inclined surface is formed in a further embodiment with retracted telescopic punches by the two just mentioned surfaces.
