Definitions

  • the invention relates to a scanning lock in a lock cylinder with a cylinder core, which is rotatably mounted in a cylinder housing and with a plurality of holes penetrating the cylinder housing and continuing in the cylinder core, in which core and housing pins loaded by springs together with and surrounding at least one housing pin this freely displaceably mounted, open-sided, tubular sleeve can be moved into a release position by a key from a locked position, in which the housing pins are located in the dividing surface between the cylinder core and the cylinder housing (cf. preamble of claim 1).
  • Such an arrangement is known from CH-A-671428.
  • the burglars In order to move the tumblers of a locking cylinder, i.e. the core and housing pins that can be moved in the bores, into the release position, the burglars use the Hobbian scanning method. It can be assumed that due to design-related play or tolerances, a cylinder core in the cylinder housing can also be rotated slightly in the locked position. The burglar applies a small amount of torque to the cylinder core and moves the core pins sensitively using a narrow knife-like tongue in the key channel, hoping to be able to feel the pitch of the core and housing in the bore. If this is successful with a guard locking, then not much is gained from it, because manipulating the next guard locking often means that the division previously obtained is lost.
  • a two-part tumbler pin is known, which is formed from a core and a cap placed with radial play in the form of a sleeve pot closed on one side.
  • the core and cap can only be moved together from the key channel.
  • the invention aims to prevent scanning according to the Hopp principle, in particular by a scanning method with an impact on the tumblers. This is achieved in that the end face of the sleeve facing the core pin is at least in the locked position at a distance from the end face of the core pin facing the housing pin.
  • the housing pin runs empty with respect to the sleeve. If the sleeve has annular grooves on its outer surface, then such an annular groove can snap onto the step of the bore between the core and the housing, thereby pretending to achieve division.
  • Fig. 1 shows a locking cylinder with scanning security in longitudinal section
  • Fig. 2 shows the scanning security on an enlarged scale in detail.
  • a cylinder core 2 is rotatably supported in a cylinder housing 1.
  • Core holes 4 and housing pins 5 are provided in bores 3 and are biased by springs 6 in the direction of the key channel 7. With the right key, but also with an intrusion tool, the pins 4, 5 are moved against the force of the spring 6, with the aim of moving the contact surface of the pins 4, 5 into the cylinder surface between the cylinder core 2 and the cylinder housing 1. If this succeeds with all pins, then the cylinder core 2 can be rotated in the cylinder housing 1.
  • Fig. 1 five tumblers are shown, each consisting of a core pin 4 and a housing pin 5.
  • a core pin 9 is provided only in a bore 8, which bears against a spring-loaded housing pin 10, which is reduced in diameter over part of its length and carries a sleeve 11 there. The full pin diameter is only present at the end of the housing pin 10 facing the spring 12.
  • the sleeve 4 slides in the bore 8 and the housing pin 10 slides on the inside of the sleeve 11.
  • the housing pin 10 projects somewhat beyond the sleeve 11 in the contact area with the core pin 9.
  • the core pin 9 transmits it to the housing pin 10 and also to the sleeve 11. Because of the structural design and the mass ratios, the housing pin 10 vibrates primarily inside the sleeve 11. It was found that the latter hardly moved and therefore in the locked position remains.
  • the scanning method based on the transmission of vibrations by means of a blow or also by means of a vibrating tongue fails.

Claims (3)

  1. Dispositif de sécurité de palpage dans un canon ou cylindre de serrure muni d'un noyau de cylindre (2) monté rotatif dans un boitier de cylindre (1) et de plusieurs alésages (3, 8) traversant le boîtier (1) et se prolongeant dans le noyau de cylindre (2) et dans lesquels des paillettes ou barrettes de noyau et de boîtier (4, 5; 9, 10) sollicitées par des ressorts (6; 12) sont susceptibles d'être déplacées dans une position de libération par une clé; toutes ensemble avec un manchon (11) entourant au moins une paillette de boîtier, monté librement glissant sur cette paillette ouvert des deux côtés et en forme de petit tube, à partir d'une position de blocage dans laquelle les paillettes de boîtier (5, 11) sont disposées sur la surface de séparation entre le noyau de cylindre (2) et le boîtier de cylindre (1), caractérisé en ce que la face frontale du manchon (11) tournée vers la paillette de noyau (9) est disposée, au moins en position de blocage, à distance de la face frontale de la paillette de noyau (9) tournée vers la paillette de boîtier (10).
  2. Dispositif de sécurité de palpage selon la revendication 1, caractérisé en ce que la paillette de boîtier présente, uniquement dans la zone de l'extrémité sur laquelle s'appuie le ressort (12) un diamètre qui, au jeu près, atteint le diamètre intérieur de l'alésage (8) et en ce que la paillette de boîtier (10) se raccorde à cette zone jusqu'à son extrémité opposée par une partie dont le diamètre est réduit des épaisseurs de paroi du manchon (11) entourant cette zone.
  3. Dispositif de sécurité de palpage selon la revendication 1 ou 2, caractérisé en ce que la partie de diamètre réduit de la paillette de boîtier (10) est plus longue que le manchon (11) monté sur elle.
