Definitions

  • the invention relates to a tumbler according to the preamble of independent patent claim 1.
  • Rotary cylinder locks with tumblers of this type are generally known and generally have a high security value.
  • opening methods have been developed with which these rotary cylinder locks can be opened without a key and without external damage to the locks. With these opening methods it is generally not possible to secure evidence.
  • the invention is based on the object of creating a rotary cylinder lock of the type mentioned, in which these opening methods are ineffective and which nevertheless functions properly and can be produced inexpensively.
  • the invention has the further advantage that, apart from the core pin, the rotary cylinder lock can be designed as usual.
  • the known rotary cylinder locks for flat or wrenches can thus be used.
  • the core pin can be manufactured in a simple manner are and is therefore also suitable for equipping series-produced rotary cylinder locks.
  • the tip of the core pin By manufacturing the tip of the core pin as a separate part, it is possible to manufacture it from a hard metal material, so that the rotary cylinder lock is more secure against drilling and the control surface does not wear out even with frequent use.
  • the development of the invention according to claim 7 has the advantage that, in addition, opening methods are also ineffective, in which an attempt is made to measure the effective part of the guard locking.
  • the lock cylinder partially shown in FIG. 2 has, in a known manner, a stationary cylinder housing 12 which is inserted in a cylindrical sleeve 11 and in which a cylinder core 13 is rotatably arranged.
  • the cylinder housing 12 and the cylinder core 13 have radial bores 17 in which spring-loaded two-part tumblers are slidably mounted.
  • a compression spring 16 which is supported against the sleeve 11 and which presses with pretension on a housing pin 15 which in turn presses a core pin 10 radially inwards against a key to be inserted into the key channel 14.
  • the core pin 10 has a body 1 with an axial stepped bore 27, in which a correspondingly stepped locking pin 24 is slidably mounted.
  • the core pin 10 has a separately manufactured tip 3 with a head 3b and connecting part 3a, which is inserted with a firm fit into the bore 27.
  • the tip 3 can be made of a different material than the other parts of the core pin.
  • the tip is preferably made of a drill-resistant and abrasion-resistant hard material, for example a suitable hard metal material.
  • a compression spring 25 which is supported against the point 3 and presses with pretension on the locking pin 24.
  • the locking pin 24 is designed such that it protrudes from the bore 27 when, as shown in FIG. 1, it is only loaded by the compression spring 25. If the core pin 10 is inserted into the rotary cylinder, the compression spring 25 counteracts the stronger spring 16 and holds the locking pin 24 in the recessed position shown in FIG. 2. As a result of the tension of the compression spring 25, the locking pin 24 presses against the housing pin 15 without, however, moving it out of its position locking the rotary cylinder.
  • the mode of operation of the guard locking in the event of an unauthorized opening attempt is to be briefly explained with reference to FIG. 3b.
  • the housing pin 15 has been briefly moved into an unlocked position by a known opening method, the core pin 30 remaining in its original position.
  • the two tumbler pins have been blown apart. If this is possible with a conventional rotary cylinder lock for all tumblers at the same time, the cylinder core 13 can be rotated in a short time interval and the lock can be opened.
  • the locking pin 24 follows the housing pin 15, which moves radially outward, essentially without delay due to the pressure of the spring 25.
  • the locking pin 24 reaches over it and locks the rotary cylinder.
  • the locking pin 24 remains in its locking position until it is pressed back into its original position (FIG. 3a) by the housing pin 15.
  • a core pin 30 is provided. As shown in FIGS. 3a and 3b, this has, in addition to the locking pin 24, a sleeve-shaped sliding element 31 which is displaceable in the longitudinal direction on the pin body 1 and in the bore 17 in the cylinder core 13. The sliding element 31 is lowered in a step-like manner in accordance with the bore in the cylinder core 13. The sliding element 31 accordingly experiences a stop radially inward in the bore 17. Also correspondingly step-shaped is the pin body 1, which experiences a stop radially inward on the step-shaped inner surface of the sliding element 31.
  • FIG. 4 Another and particularly inexpensive embodiment of a tumbler according to the invention with a core pin 40 is shown in FIG. 4.
  • the core pin 40 has a body 46 with a cylindrical blind bore 42, into which a likewise cylindrical locking pin 41 is inserted.
  • the housing pin 15, against which the locking pin 41 abuts under the pressure of a spring 45, is designed as described above.
  • the body 46 shown here is rounded at the tip and is intended for a rotary cylinder lock with a wrench (Yale cylinder).
  • the core pins 10 and 30 can be inserted into conventional rotary cylinders and work in the same way as the known core pins when actuated with the assigned key.
