Definitions

  • the invention relates to a cylinder lock comprising a safety metalwork, which can be secured in a door or the like, a cylinder housing to be fixed in relation to said metalwork, said housing containing an inner cylinder in which a key can be inserted so that the inner cylinder can be rotated and the bolt of said lock can be operated.
  • Such cylinder locks are widely used. However, a difficulty thereof is that they are not burglar-proof in every aspect. For example, it is possible to screw a tap bolt into the inner cylinder by means of which then the inner cylinder and a portion of the cylinder housing can be pulled out. After that, the operating mechanism of the bolt of the lock is easily accessible and the door or the like can be opened.
  • the object of the invention is to remove this difficulty and to that end provides for, that a tilting pin comprising a head and a shank is mounted in the cylinder housing in such a way that the head of the tilting pin is located in a recess in the wall of the cylinder housing and its shank protrudes beyond the cylinder wall, said tilting pin being formed such that its head, being received in the recess, protrudes in relation to the shank of the tilting pin, at least in the direction towards said safety metalwork.
  • the tilting pin will consist of two cylindrical, coaxial parts with the head having a larger diameter than the shank. This enables simple manufacturing of the tilting pin. Then the recess in the wall of said cylinder housing, in which the head of the tilting pin is to be mounted, will also have a simple form. At the same time it is achieved that the shank of the tilting pin, on tilting the pin, will not directly contact the wall of the recess in the cylinder housing.
  • the tilting pin must be able to tilt in relation to the cylinder housing wall but should be fixedly mounted in it, so that it can not drop out of the recess and into the cylinder housing.
  • the head of the tilting pin can be secured by means of a ligh drive fit or by glueing or in a like way.
  • Fig. 1 shows a cylinder housing 1 having in its part at the far right an inner cylinder 2 indicated only by some dash lines. A key can be inserted into the inner cylinder.
  • the cylinder housing 1 is received in a safety metalwork 3, which can be fastened onto a door or window.
  • a recess is made in the wall 4 of the cylinder housing 1, in which recess a tilting pin 6 is received, in particular its head 7, see Fig. 2, in such a way that the shank 8 of the tilting pin 6 protrudes beyond the cylinder housing 1.
  • the head 7 can be secured in the wall 4 by light drive fit or by glueing.
  • the cylinder housing 1 When someone tries to pull the inner cylinder 2 out with force in the direction of the arrow P, the cylinder housing 1 will break at the location of the transition 9 between both cylindrical parts, as shown in Fig. 3. Then, the shank 8 of the tilting pin 6 contacts the safety metalwork 3 and the pin will tilt as shown in Fig. 3. Due to that, a part of the edge 10 of the head 7 of the pin 6 will engage the inner cylinder 2 and will grasp into it. The opposite part of the edge 11 of the head 7 will at the same time grasp into the wall of the cavity in the safety metalwork 3, in which cavity the cylinder housing 1 is received.
  • the cylinder housing 1 and the inner cylinder 2 can not be pulled out further, so that the lock is protected against burglary.
  • the tilting pin 6 need not consist of cylindrical parts but said parts can also have a more rectangular shape.
