Definitions

  • the invention relates to a closure system according to the preamble of independent claim 1.
  • Such a system is known from US-A-3 793 857.
  • This system has a locking element which can only be brought into a position releasing the locking cylinder when a slide connected to the locking element and displaceable transversely to the lock axis can be inserted into a by means of a pin which can be inserted into an opening of the locking cylinder and then moved on a circular path Recess is insertable on the circumference of the cylinder core.
  • the cylinder core can only be rotated with the key into a position in which the recess receives the slide.
  • the invention has for its object to provide a closure system of the type mentioned, which offers high operational reliability with a simple structure.
  • the object is achieved by the invention according to claim 1.
  • the cylinder core only has to be turned to the position in which the two passages are in register.
  • a mandrel inserted into the passages from the outside of the locking cylinder, for example a bent-up bureau clip
  • the locking element is brought into a unlocking position and the locking cylinder is pulled out of the guide sleeve.
  • the new locking cylinder is then inserted into the guide sleeve, the locking element automatically snapping into the groove of the guide sleeve.
  • the exchange can thus be carried out in a simple manner and with a few handles and does not require any manual skill.
  • the invention makes office systems possible in which every employee takes his locking cylinders with him when changing offices and the locking cylinders can be replaced without specialist personnel. It is essential that the two passages can only be made to coincide with the help of the key belonging to the locking cylinder.
  • the cylinder core has a recess on its lateral surface behind its passage, into which the locking element can escape when the locking cylinder is released, this recess only extending over part of the circumference of the cylinder core. This prevents the locking cylinder from being drilled through at a suitable point and the locking element being brought into the position that unlocks the locking cylinder.
  • the lock cylinder to be replaced is pulled forward out of the guide sleeve and not backwards as before.
  • a locking element in a lock cylinder is known from DE-A-36 03 655. With this, the cylinder core and not the locking cylinder as a whole is replaced. To release the locking element, a pin is inserted through the key channel into a pin channel of the cylinder core when the key is removed.
  • a sleeve 3 is inserted into a bore 2 of a wall 1 or the like of a piece of furniture and screwed tight.
  • a locking cylinder 4 with a cylinder housing 5, a cover sleeve 6 and a cylinder core 7 rotatably mounted in the housing 5 is inserted into the bush 3 from the front.
  • the cylinder core 7 is axially secured in the cylinder housing 5 with a snap ring 8 at the rear end and a collar 9 at the front end.
  • a locking element 11 is inserted, which engages with two angled locking parts 13 in a groove 12 in the inside of the sleeve 3 and thereby axially fixes the locking cylinder.
  • the locking element 11 between the locking parts 13 has an actuating part 14 which is bent toward the cylinder core 7 and on which the free end of the locking element is deflected by a leaf spring 16 against the force to the cylinder core 7 against the force can be until the two locking parts 13 no longer engage in the groove 12 and the lock cylinder 4 can be pulled forward out of the sleeve 3.
  • a known clutch is released.
  • the actuating part 14 dips into a recess 17 in the lateral surface of the cylinder core 7.
  • This recess 17 extends only over a small part of the circumference of the cylinder core 7 and is only in the area of the locking element 11 when the locking cylinder 4 is in the change position shown in FIG. 1. Outside of this position, the locking element 11, after a slight deflection with the actuating part 14, abuts the outer surface of the cylinder core 7, so that the locking parts 13 cannot be brought out of the groove 12.
  • the cylinder core 7 has a passage 18 on the collar 9, which, when the cylinder core 7 rotates, for example by 90 °, into the change position and for covering is brought with a passage 19 in the cylinder housing 5.
  • the pin 15 is inserted through the passages 18 and 19 to replace the locking cylinder and is placed on the actuating part 14.
  • the key not shown, is of course inserted into the key channel 20.
  • the replacement locking cylinder is inserted into the sleeve 3 from the front, the locking element 11 automatically snapping into the groove 12 and the coupling to the drive element being produced.
  • a locking system results from the above information, which can obviously be realized with relatively few, simple and robust components and which not only takes the security requirements into account in an excellent manner, but also enables the locking cylinder to be replaced in a very simple manner.
