Definitions

  • the invention relates to a pin lock with a cylinder rotatable in a bore of a housing, which has a number of radial bores which lie in a radial plane of the cylinder and which on the one hand open into a key channel and on the other end at the circumference of the cylinder, a number of bores in the housing, each of which forms an extension of the bores in the cylinder in an angular position of the cylinder, pins in the bores of the cylinder and the housing, which are pressed by springs in the direction of the cylinder, the length of the pins being such that when Introducing a coded key into the key channel in the angular position mentioned, the contact surfaces of the cylinder pins and the corresponding housing pins are in the lateral surface of the cylinder and at least certain pins have an enlarged head at one end and also a head at the other end, both heads have the same diameter and in between In the two heads there is a zone with a smaller diameter.
  • Such a lock is known from DE-A No. 628600.
  • These known locks offer a high level of security, but are nevertheless relatively easy to overcome when trying to open them with a lock pick.
  • One of these opening methods is to lift the pins against the action of the return springs with the help of suitable instruments and to turn the cylinder slightly. As a result, the housing pins are clamped in the housing and the cylinder pins can move freely.
  • the invention has for its object to improve a pin lock of the type mentioned in such a way that the lock cannot be opened by clamping the pins due to twisting of the cylinder.
  • this object is achieved in that the height of the enlarged heads of the cylinder pins is smaller than the gradation of the beard of the lock and the enlarged heads are connected to the zone with a smaller diameter by a bevel of approximately 45 °.
  • the cylinder has greater rotational play when the pins are lifted so that the head of the cylinder pins penetrates the housing, but the rest remains in the cylinder, preventing the cylinder from rotating freely.
  • a particularly simple manufacture of the pins is achieved when the enlarged head is shaped by parting off.
  • the lock consists of a housing 1 with a cylindrical bore 2, in which a cylinder 3 is rotatably arranged.
  • the cylinder 3 has an elongated key channel 4, into which radial bores 5 open, all of which lie in a radial plane of the cylinder 2.
  • the bores 5 also end at the circumference of the cylinder 3.
  • the housing 1 has a number of bores 6, which are each aligned with the bores 5 in an angular position of the cylinder (shown in FIGS. 1 to 4).
  • a pair of pins (tumblers) is housed, which consists of a cylindrical pin 7 and a housing pin 8 and of a spring 9, which is arranged between the bottom of the bore 6 and the pin 8, in the direction of the Key channel 4 is pressed.
  • At least certain cylindrical pins have an enlarged head 10 at their outer end.
  • the head 10 is formed by parting off, a second head 11 having the same diameter as the head 10 being formed at the inner end.
  • the zone 12 of the pin 7 between the heads 10 and 11 has a smaller diameter, and the heads 10, 11 guide the pin in the bore 5.
  • the head 10 is expediently connected to the zone 12 by a bevel of approximately 45 °.
  • the height of the head 10 is smaller than the gradation of the beard of the lock, so that the head 10 is completely outside the cylinder 3 at the next higher step.
  • all the cylindrical pins 7 have an outer surface ren head 10 and an inner head 11.
  • the housing pins have the same shape with an inner head 13, an outer head 14 and an intermediate zone 15 with a smaller diameter.
  • certain housing pins 8 'and certain cylindrical pins 7' have no heads 13 or 10.
  • the height of the intermediate zone 12 ' is smaller, so that the inner heads 11 are replaced by an elongated zone 11 ', the diameter of which is equal to that of the head 10.
  • Certain housing pins 8 can have the same shape.
  • the head 10 If the burglar slightly reduces the pressure in the direction of arrow F, the head 10, thanks to its 45 ° bevel, engages under the force of the spring 9 against the opening of the bore 6 and the pin 7 cannot slide any further downwards.
  • the effect of the heads 13 on the housing pins 8 is similar.
