Definitions

  • the invention relates to a lock cylinder with a cylinder core guided in a cylinder housing bore, each passing through two pin tumblers arranged in planes arranged at right angles to the cylinder core axis, which are parallel to one another and at the same distance from the parallel core diameter and are connected to one another by a web to which the key is connected its incisions, whereby a suitable key brings the pin pairs into a position in which the ends of the pin pairs do not protrude beyond the cylinder core shell, and if the key does not match or is removed, the ends of one side of the pin pairs extend into recesses in the cylinder housing.
  • Such a locking cylinder is known from US Pat. No. 3,058,336.
  • the two pin tumblers are in a single recess in the cylinder housing, so that in the locked position only one of the two pin tumblers is always locking.
  • the tumbler ends are hemisphere-36 137 EU HC / Be designed so that the tumbler ends must lie far into the recesses in the cylinder housing in order to be able to have a locking effect.
  • the H-shaped tumblers are only guided through the cylinder core in the outer areas so that they cannot withstand greater forces. A somewhat exact actuation of these poorly guided tumblers is only achieved in that the key shaft is U-shaped and actuates the tumblers with a double row of key cuts.
  • the cylinder core consists of two halves, the assembly of which includes the tumblers and two springs per tumbler.
  • German Patent Specification 1,060,737 it is known from German Patent Specification 1,060,737 to arrange an intermediate part in the recess in the cylinder housing provided for a tumbler plate. This intermediate part is only intended to guide the back of the key shaft.
  • the object of the invention is to improve a locking cylinder of the type mentioned in such a way that a high number of locks can be achieved with a simple construction and assembly and even a small emergence of the tumblers over the cylinder core jacket leads to locking in both directions of rotation.
  • the key channel arranged in the cylinder core on the diameter receives the shaft of a flat key, which rests centrally on the webs of the pin pairs.
  • Usual flat keys can be used for the cylinder core.
  • a spring may engage the web on each pin p aar centrally. This means that not only a single spring per pair of pins is sufficient, but no additional projection on the pair of pins is required for the spring. Rather, it is sufficient if the spring engages the web of the pair of pins, which is also actuated by the key.
  • the spring as a helical spring lies coaxially on the diameter of the cylinder core parallel to the pins.
  • a particularly wide blocking edge of the pins as well as a high stability is achieved in that the pins are rectangular in cross-section, in particular almost square, the longitudinal edges of the pins preferably being chamfered at an angle of 45 °. By chamfering the pins, great smoothness and insensitivity to imprecise channels in the cylinder core are also achieved.
  • a particularly space-saving design is achieved in that the web with respect to the pin ends except is in the middle.
  • the web can be shifted towards the spring.
  • the spring be in the smaller or shorter space between the pins of a pair and the key channel in the larger or longer space.
  • a very simple manufacture of the pins is achieved in that a pair of pins is cast together with the bridge in one piece from metal.
  • a particularly simple manufacture of the cylinder core as well as a simple mounting of the spring is created in that the cylinder core outer wall forms a web between the pins of a pair, on the inside of which the spring rests.
  • the side surfaces of the pins and the web and, if appropriate, the longitudinal strips be arranged in one plane on a broad side of a double pin. This not only increases the stability of the pair of pins, but also allows the intermediate webs or intermediate walls in the cylinder core to be straight at least on one side. This leads to simpler manufacture, greater stability, better demoldability and a shorter overall length of the cylinder core.
  • a pair of pins form an H-shaped plate tumbler.
  • a particularly advantageous embodiment of the invention is achieved in that two platelet tumblers.
  • two pairs of pins lie in a single recess of the cylinder core and adjoin one another, and that the central web of each plate-like tumbler or
  • Pin pair protrudes over a side surface and in the central space of the adjacent tumbler or
  • a very low-friction and therefore easy actuation of the locking devices is ensured by the key, since the areas of the locking devices that are in contact with the key and acted upon by the key can be larger than the thickness of each locking device. Furthermore, a high number of increments can be achieved. Such an embodiment can also be carried out and is advantageous if no intermediate parts are provided in the recesses of the cylinder housing provided for the tumblers. The end faces of the locking devices do not need to be beveled either.
  • the web has approximately twice the depth or thickness as the thickness of a plate-like tumbler or pin pair.
  • the surface of the web that scans the key can form two inclined surfaces whose cutting line (control edge) lies approximately at the level of the boundary plane or side surfaces between the pair of plate-like tumblers or pairs of pins.
  • Main and secondary locking systems can be achieved in that the web has two scanning surfaces or control edges of different heights for two different key shaft profiles side by side. It is also proposed that in one of the legs of the plate-like tumblers or in one of the pins a longitudinal recess is provided on the side facing the adjacent tumbler and the adjacent tumbler has a corresponding longitudinal recess, with a helical compression spring in each of the two recesses lies. This enables a particularly space-saving arrangement of the spring acting on the tumblers. Also, each tumbler no longer needs its own spring, but a single spring is sufficient for a pair of tumblers. Each recess can be semi-cylindrical.
  • a secure mounting of the spring in the tumblers is achieved in that a projection of each tumbler bearing one end of the helical compression spring projects into the recess of the adjacent tumbler. It is also proposed that, in the case of a pair of tumblers, the web of one tumbler on one side, in particular the narrow side, scans the key shaft and the web of the second tumbler on the opposite side.
  • the cylinder core 1 has pocket-shaped recesses 2 transverse to its axis of rotation, which are shaped in accordance with the cross section of double tumblers (pairs of pins) 3.
  • the recesses 2 have a flat wall 2a, on which the flat back of the double tumbler 3 comes to rest.
  • the opposite wall 2b of the recess 2 has two strip-shaped webs 2c, which extend into the double tumbler 3 to about half its thickness.
  • Each double tumbler 3 has two mutually parallel pins 4 which are of equal length to one another and to the pins of the other double tumblers.
  • the pins 4 lie in tendon-shaped, parallel channels of the cylinder core, which form part of the recesses 2.
  • the channels open into the cylinder core jacket on both sides, so that the pins can emerge on both sides of the cylinder core.
  • the pins 4 protrude with one of the two ends into recesses 5 of the cylinder housing, a recess 5 being provided for each end of a pin 4.
  • the recesses are only provided in the rotational positions of the cylinder core in the cylinder housing that are intended for key removal.
  • the inner surfaces i.e. the surfaces 8 of the pins 4 facing the opposite pin come to rest on the side surfaces of the intermediate part 6 and act there as a block.
  • the end faces 9 are designed obliquely, in particular arched, in accordance with the cylinder core outer wall and form an acute angle ⁇ with the face 8.
  • the surfaces 8 and 9 form a sharp edge 10 parallel to the axis of rotation, which locks in the recess 5 with respect to the intermediate part 6 or the sharp edge 11 of the intermediate part 6 even after a slight emergence from the cylinder core.
  • the double tumbler 3 is cast in one piece from metal and consists of two almost square pins 4 with a rectangular cross-section, on the inside of which two longitudinal strips 12 are formed, which are connected to one another by a web 13.
  • the parallel to the pins 4 longitudinal sides 12 are shorter than the pins and form contact surfaces on both end faces Chen to come to rest on one side on a web 14 of the cylinder core and on the other side on the intermediate part 6.
  • the freedom of movement of the double tumblers can thus be determined very precisely.
  • the longitudinal strips 12 guide a helical compression spring which rests on the web 13 and rests with its opposite end on the web 14 of the cylinder core. On the side of the web 13 opposite the spring, the web 13 can be moved through the shaft of a flat key.
  • the web 13 has roof-shaped surfaces 14 on the side facing the key, which correspond to the key incisions.
  • the web 13 is eccentric, namely displaced towards the spring 15. This gives the key channel more space than the spring, which requires little space.
  • the longitudinal edges of the pins 4, which are approximately square in cross section, are chamfered or chamfered at 45 ° in order to ensure that the double tumblers slide safely.
  • the web 13 In the direction of the longitudinal axis, the web 13 has an insignificantly smaller width than the pins 4 in order to provide a bearing surface for the spring and also sufficiently large surfaces 14 for the key.
  • the longitudinal strips 12, however, are made less wide.
  • the lock differs from the first exemplary embodiment in that two in particular plate-like tumblers 30, 31 are arranged in a single recess 2 of the cylinder core 1. That the cylinder Core 1 surrounding cylinder housing 7 thus also has common recesses for the tumbler pair, an intermediate part 6 being provided in the cylinder housing recesses.
  • the H-shaped tumblers have a web 13 connecting the pins or legs of the tumbler, the width B of the web being measured transversely to the longitudinal direction of the tumbler and / or the pins or legs, approximately equal to the width or slightly less than the width of the gap, distance or space 32 between the pins or legs.
  • Both webs 13 of a pair of tumblers have a thickness D which is approximately twice as large as the thickness of a tumbler, the region of the web 13 which protrudes beyond the side surface 33 of a tumbler projecting into the space 32 of the adjacent tumbler and being guided there is.
  • the two plate tumblers 30 and 31 are arranged so that the web 13 of one tumbler is located near one end of the tumbler and the web of the other tumbler on the opposite side.
  • the webs 13 of the tumblers therefore have a region which is twice as large for forming control edges 34 and contact surfaces 35 for the key profiles.
  • the flat key in the area of the shaft has two key profiles each with differently graduated heights for the control edges of the webs arranged at different heights, the webs of each tumbler also have two different control edges and associated contact surfaces.
  • the control edges and contact surfaces are one Tumbler of a pair on a first narrow side of the key shaft, and the control edges and contact surfaces of the other tumbler of the same pair on the opposite narrow side of the key shaft.
  • a spring is not provided for the two tumblers of a pair lying in a single cylinder core recess, which press the control edges and contact surfaces towards the key profile, but rather the tumblers of a pair are acted upon by a single helical compression spring 34.
  • the two tumblers in the side surfaces 33 with which they abut one another, have a longitudinal recess 35 in one of the pins or legs, each of the longitudinal recesses being semi-cylindrical, so that the two longitudinal recesses of both tumblers of a pair together form a cylindrical space in which the helical compression spring 34 is inserted.
  • the recesses 35 each form a projection 36 which projects beyond the side surface 33 and extends into the recess of the adjacent tumbler, as a result of which the ends of the helical compression spring 34 are securely mounted.
