Definitions

  • the invention relates to a keyless, mechanical, codable lock construction according to the preamble of patent claim 1.
  • a lock is also known according to the preamble of patent claim 1 (US-A-3910078), in which the inserts are moved in the pushing direction of the push buttons and are held in the end position by leaf springs. Recoding takes place after removing a cover by rotating the inserts by 180 °.
  • the object of the invention is to provide a lock construction which can be operated easily and can be easily recoded without specialist knowledge and without disassembling the lock construction.
  • the inserts are removable from the grooves, have asymmetrically arranged recesses in their other longer side edge and this other longer side edge of the inserts is beveled at both ends - expediently at an angle of 10 to 45 °.
  • the stop surface parallel to the shorter side edges of the inserts is expediently formed between the other longer side edges of the inserts and the bevels.
  • the direction of displacement of the switching elements is perpendicular both to the direction of displacement of the rack and to the direction of displacement of the inserts.
  • the one bevel of the inserts is in contact with the associated switching element and the shorter side of the inserts, which is provided with the other bevel, is arranged in a contacting manner, with a reset which resets the lock construction to the initial position and which can be tilted about an axis parallel to the direction of displacement of the rack .
  • the lock construction has a cylindrical opening member rotatable about its axis and provided with at least one cam in its jacket area touching the reset element and that the reset device is provided with at least one web projecting from its surface contacting the opening element.
  • the opening member has at least one cam-like guide element for displacing the rack in its jacket region touching the rack.
  • At least one cutout suitable for receiving the toothed rack is formed in the center of the cam-like guide element (s), the opening member being displaceable in the direction of its own axis and can be coupled to a rotary shaft actuating a locking bolt, when the rack is in the cutout (s) of the guide element (s).
  • the opening member 6 is advantageously disc-shaped and at least one cam-like guide element 27 for displacing the rack 15 is formed on its jacket. At least one cutout 32 suitable for receiving the rack 15 is formed in the middle of the guide element (s) 27 . If the toothed rack 15 is located in the cutout (s) 32 of the guide element (s) 27, the opening element can be displaced in the direction of its own axis and can be coupled to a locking bolt 13 by means of the rotary shaft 8.
  • the ste with the reset 18 in contact The lateral surface area of the opening member 6 is provided with at least one cam 25, while at least one web 26 protruding from this surface is formed on the surface of the reset device 18 in contact with the opening member 6.
  • An opening rod 12 is guided in a bore perpendicular to the longitudinal axis of the base body 1 and parallel to its flat side, the movement of which is determined by the path of a threaded bolt 11 in the base body 1, which is screwed into the opening rod 12.
  • the threaded bolt 11 fits into the notched part of the opening plate 9.
  • An adjustable locking bolt 13 is connected to the end of the opening rod 12 by a screw connection and is held in its basic position by the tensioning force of a spring 14.
  • the position of the reset device 18, which can be pivoted by two bolts, is determined either by the displacement of the inserts 16 or by the rotation of the opening member 6 in different positions.
  • the inserts 16 are guided or held in the base body 1 by a locking plate 17 and this locking plate 17 is detachably fastened to the base body 1 by screws 22.
  • the lock construction is fastened to the door by the back plate 4 using cap nuts 20 in such a way that the front plate 5 and the back plate 4 are pressed onto the inside and outside surface of the door.
  • the front plate 5 is fastened to the base body 1 with the aid of nuts 21.
  • the opening member 6 has two such positions in which the switching members 2 can be pressed in in a manner suitable for actuation. Of these two positions, however, it is only possible to actuate them correctly in one position. In the other positions of the opening element 6 (FIGS. 5 and 6), the switching elements 2 are locked and cannot be pressed in. In the correct opening member position (FIG. 7), but also in the position suitable for pressing in but not suitable for opening, the associated insert 16 provided with the cutouts 24 and the reset device 18 are pressed once or several times when any switching element 2 is pressed in postponed. With regard to the actuation of the lock construction, the actuation of some switching elements 2 is justified and others are not. The correct actuation is determined by the code programmed in each case. An incorrect setting or an actuation deviating from the code excludes the possibility of opening.
  • the opening element 6 can be rotated so that its cam-like guide element 27 moves the rack 15 against the spring 19, after which the upper end of the rack 15 in the cutout 32 of the guide element 27 jumps in.
  • the lower part of the opening member 6 provided with a rib 30 can be pressed against a spring 7 into the rotary shaft 8 provided with a groove 31 and coupled to it (FIG. 12).
  • the rotary shaft 8 is also rotated and with the aid of the opening plate 9 and the threaded bolt 11 which are attached to the rotary shaft 8, the locking bolt 13 fastened to the opening rod 12 and biased by a spring 14 is displaced (FIGS. 13 and 15).
  • the opening member 6 is designed so that it resets all the inserts 16 into the starting position in its initial position, but also in the position coupled to the rotary shaft 8 and rotated for opening - with the simultaneous rotation of the reset means 18. This means that the lock cannot be accidentally left open. A renewed opening is only possible by repeated actuation of the switching elements 2 according to the code.
  • the opening member 6 When released, the opening member 6 is returned to its original position by the spring 7 in the twisted position assumed after the opening, in which the lock cannot be opened.
  • the rotary shaft 8 is also returned to the starting position by the spring 14 returning the locking bolt 13 by means of the opening plate 9 coupled to the opening rod 12 during the return of the opening member 6 to the starting position (FIG. 13). In this position, the part of the opening member 6 provided with the rib 30 and the groove 31 of the rotary shaft 8 can only meet if the opening member 6 is rotated after a further coded pressing.
  • the rotary knob 10 located inside can be rotated freely, as a result of which the locking bolt 13 can be moved.
  • the door is closed with a single movement, by gently pushing the door shut.
  • the setting or change of the program takes place in the installed state of the lock construction from the inside, after unscrewing the back plate 4 and the locking plate 17.
  • the desired insert 16 is used in the solution shown in the example lifted out and returned to its place after being rotated in the longitudinal direction by 180 °. Then the locking plate 17 and the back plate 4 are screwed on again.
  • the lock construction according to the invention makes the installation of an additional security lock unnecessary due to the numerous, several million resulting possible variations.
