Definitions

  • the invention relates to a cylinder lock with a cylinder core rotatable in a cylinder housing, which has a profiled, longitudinal key channel for accepting a key and transverse guide channels which are connected to the key channel, open to both ends of the outer surface of the cylinder core and accommodate spring-loaded pin tumblers which have a straight, prismatic shape with a regular cross-section and the length of which corresponds to the length of the guide channel in which they slide, the key having incisions of different heights, in each of which there is a projection of the pin tumbler after the key has been inserted completely into the key channel.
  • the pin tumblers consist of stamped plates, so-called plate tumblers.
  • Each tumbler contains a right-angled central window for the key, and the position of this window determines the height of the stop which is created by the narrow side of the window in connection with the incisions of the key under the action of a return spring.
  • This padlocked tumbler lock is difficult to assemble due to the number and variety of parts that make it up. There are just as many different tumblers as incision heights to create the combination, and each tumbler is subject to the action of a spring. In addition, measures must be taken to prevent the tumblers from coming out of the cylinder core completely in order to facilitate the assembly of the cylinder core in the stator without a key.
  • This lock with tumblers also offers limited mechanical resistance, especially with punched tumblers, so that it has been proposed to use cast plates of greater thickness, which offer greater resistance.
  • the object of the invention is to reduce these disadvantages of the known cylinder lock by using mutually identical pin tumblers with a large cross section.
  • This object is achieved according to the invention in that each longitudinal side of the pin tumbler has a projection of longitudinal height, which differs from the height of another side, the guide channels of the cylinder core have a polygonal cross section, only one projection at each rotational position around its axis of the pin tumbler is connected to the key incisions, the guide channels have an extension for the protrusions of the pin tumblers and the protrusions are formed by a circumferential excess thickness or collar of larger diameter.
  • the manufacture of the pin tumblers can be performed in a very simple manner in very high series, e.g. by casting, especially injection molding.
  • each pin tumbler is subject to the action of at least one prong of a single spring in the form of a comb, connected to the cylinder core.
  • the invention also relates to a machine for the automatic production of the cylinder core of the lock mentioned at the beginning.
  • This machine has a reading device for the profile of the key and a carriage for transporting the cylinder core, which is aligned by the reading device in accordance with the channels of the cylinder core.
  • the machine according to the invention differs from a known machine of this type (US Pat. No.
  • the machine has a vibration generator for positioning and displacing pin tumblers, a gripping device for receiving and aligning the pin around its axis according to the Program of the electronic reader according to the profile of the key, which has a swivel arm and a supply container for transporting the cylinder core on the slide, programmed by the electronic reader, which advances them according to the channels of the cylinder core.
  • the lock contains a cylinder core 1 rotatably in a bore 2 of a cylinder housing.
  • the cylinder core 1 is traversed by exactly diametrical guide channels 4, which in the example described have a square cross section and whose cross section corresponds to the cross section of an inserted pin tumbler 5. They contain an outer area 4 '(located higher in FIG. 1) with a square cross-section as well, but with larger sides and thus a larger cross-sectional area.
  • Each pin 5 has the shape of a regular prism with sides of equal width in the exemplary embodiment with a square cross-section or base area, wherein cross-sections with a regular, triangular, pentagonal or hexagonal shape can preferably also be carried out.
  • the pin has a slightly smaller cross-section than the channel 4 for sliding the pin 5 in the channel 4.
  • the pin 5 Off-center, in particular near one end (in FIG. 2 at its higher part), the pin 5 has an excess thickness that has a collar 6 forms, the outer or higher edge 7 to the axis of the piston one has rectangular stop surface.
  • the thickness of the collar 6 is such that it can slide in the enlarged part 4 'of the guide 4, but not in the area with a smaller cross section.
  • the collar 6 On each side of the prism of the pin 5, the collar 6 at its lower part facing away from the pin end has a projection (stop) 8 extending in the longitudinal direction of the pin - triangular in the example described - or the collar has a projection 8 on each side, the tip or largest elevation of which is located at a different distance from the edge 7 on each side, so that the height H of the projection 8 is different in size on each side.
  • the active position (rotational position) of the pin 5 in its channel 4 one of its projections 8 extends into a longitudinal, profiled key channel 9 in the cylinder core 1, which is laterally connected to each of the channels 4 (FIG. 1).
  • the key channel 9 is provided for receiving a key 10 with incisions 11 which meet the corresponding projections 8 of the pins 5 during the insertion of the key.
  • each cut 11 rests on a projection 8 of a pin 5 and the height H of each projection corresponds to the depth of the cut 11 because the key 10 corresponds to the code of the lock. In this way, each pin 5 slides completely inside the cylinder core 1, and the cylinder core can rotate in the bore 2.
  • a spring 12 in the form of a comb is fastened in a recess 13 made in the jacket of the cylinder core.
  • the spring 12 contains round prongs 14, which each rest on the higher edge 7 of the excess thickness 6 of a pin 5, each pin 5 being subject to the action of two prongs 14 of the spring 12 on both sides of the pin.
  • the tines 14 cause the projections 8 to move towards the key channel and their sliding is inhibited by the contact of one of the projections 8 against the step-like surface 4 "which separates the areas 4 'and 4 of the channel the pins 5 all form the outer surface of the cylinder core 1 and their ends are pressed into a longitudinal groove 15 of the cylinder housing 3 so that the cylinder core 1 is locked in relation to the cylinder housing 3.
  • a diametrically opposite groove is in the cylinder housing 3 for sliding the pins 5 during the insertion of the key 10. If a wrong key is inserted, at least some of the pins 5 are pressed into the groove 16.
  • the cylinder core can be made of plastic.
  • the lock described is particularly suitable for automatic production.
  • FIG. 5 schematically shows a machine for the automatic production of cylinder cores corresponding to the invention.
  • the machine shown schematically here, contains a vibration generator 20 which sets up and displaces the pins 5.
  • a gripping device grips a pin 5, lifts it, rotates it about its axis according to the program of an electronic scanner 22 according to the profile of the key 10 and inserts it into the channel 4 of the cylinder core. For example, the rotation is generated by a stepper motor.
  • the gripping device 21 and the motor 23 are moved vertically by an arm 24 which rotates in one axis, thus displacing the gripping device 21 and the pin 5 in order to set it down from the starting position in the channel 4 of the cylinder core 1, which is by one Container 26 is brought up by a carriage 27.
  • the carriage 27 is programmed by an electronic reader 22 and is displaced in accordance with the distance between the axes of two channels 4 in each operation.
