Definitions

  • the invention relates to a pin lock with a cylinder which can be rotated in a bore of a housing and 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, which each form an extension of the bores in the cylinder in an angular position of the cylinder, a slide pin in each bore of the cylinder and a slide pin in each bore of the housing, which is pressed in the direction of the cylinder by a spring
  • the length of the pins is such that when a coded key is inserted into the key channel in the angular position mentioned, the contact surfaces of the cylinder pins and the corresponding housing pins are located in the outer surface of the cylinder.
  • the invention has for its object to eliminate this disadvantage of known locks.
  • this object is achieved in a pin lock of the type mentioned in that at least certain pins of the cylinder have an enlarged head at their outer end.
  • the cylinder has a greater rotational play when the pins are raised so that the head of the cylinder pins penetrates the housing and the rest
  • FIG. 1 shows a schematic cross-sectional view of a lock according to an embodiment of the invention
  • FIG. 2 shows a longitudinal section through part of the lock shown in FIG. 1;
  • FIG. 3 a view corresponding to FIG. 1 of another embodiment
  • OMPI 4 a view corresponding to FIG. 2 of the embodiment shown in FIG. 3;
  • FIG. 5 a view corresponding to FIG. 3 with an illustration of the parts in the event of a break-in attempt.
  • 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 3.
  • 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 + is accommodated, which consists of a cylindrical pin 7 and a housing pin 8 and which consists of a spring 9, which is arranged between the bottom of the bore 6 and the pin 8, in Direction on 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 part 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 part 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 at the next higher level the head 10 is completely outside the cylinder 3.
  • all cylindrical pins 7 have an outer 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' do not have heads 13 or 10.
  • the height of the intermediate zone 12 ' is small ner, so that the inner heads 11 are replaced by an extended 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.

Abstract

La serrure comprend un boîtier (1) ayant un perçage (2), dans lequel est disposé pivotant un cylindre (3) ayant des perçages radiaux se trouvant tous dans un plan radial du cylindre, et qui débouchent d'une part dans un canal (4) de la clef et d'autre part sur la périphérie du cylindre (3). Le boîtier (1) est pourvu de perçages (6) qui, dans une certaine position angulaire du cylindre (3) constituent des rallonges au perçages radiaux du cylindre (3). Dans chaque perçage du cylindre (3) et du boîtier (1) est disposée une goupille (7, 8) glissante qui est pressée par un ressort (9) dans la direction du canal de la clef (4). La longueur des goupilles (7, 8) est dimensionnée de telle manière qu'en introduisant la clef dans son canal (4), les surfaces de contact des goupilles cylindriques et des goupilles du boîtier soient disposées dans la surface d'enveloppe du cylindre (3). Au moins certaines goupilles (7) du cylindre (3) présentent à leurs extrémités extérieurs une tête élargie (10).
