Definitions

  • the invention relates to a safe lock of the type mentioned in the generic term.
  • Such a lock has become known from European Patent 0228027.
  • the electromagnetic locking device described there releases the bolt when the electromagnet receives a pulse.
  • the lock can be locked at any time by operating the handle.
  • the invention is based on the completely different object of redesigning the electromagnetic bolt lock described at the outset in such a way that it becomes effective in both directions of movement of the bolt.
  • the bolt is released for closing and opening the safe by one and the same electromagnet.
  • the user must therefore enter the same numerical code both when closing and when opening.
  • the lock is equipped with a mechanical locking mechanism, preferably a double-bit tumbler lock.
  • a mechanical locking mechanism preferably a double-bit tumbler lock.
  • the invention proposes that Detect and evaluate each opening of the safe with a microswitch.
  • Fig. 1 denotes the lock housing, which has screw holes 2, 3, 4, 5 in the corners, which are used for fastening to a security door.
  • the extended bolt 6 carries a rack 6 a, which is moved by a gear lock nut 7.
  • two base rods 8, 9 are mounted in the lock housing, the cranked end of which is designed as a toothed rack 8a, 9a.
  • Two mandrels 8b, 9b are used for guiding in elongated holes of the housing cover shown in FIG. 3. Holes 8c, 9c are used to attach extension rods. If you turn the gear 7 by about 90 ° to the right, the base rods and the latch are withdrawn so that they assume the position shown in FIG. 2.
  • a double-bit locking mechanism is arranged under an intermediate cover 10.
  • the key guide mandrel is designated 11. It penetrates the base tube 8, which in addition to the keyhole 8d has an adjoining elongated hole 8e.
  • the key can only be inserted and removed when it is locked. At open door (state according to Fig. 2) he is caught in the castle.
  • the 3 has three screw holes 12e, 12f, 12g, in addition to a keyhole 12a, the two elongated holes 12b, 12c and a further keyhole 12d.
  • the elongated holes 12b, 12c receive the mandrels 8b, 9b and guide the base rods 8, 9.
  • Fig. 4 shows the back of the lock.
  • the housing 1 has different depressions 1a and 1b in the middle and lower region.
  • an electromagnetic control is accommodated, which consists of a control slide 13, a control lever 14, a locking lever 15 and an electromagnet 16.
  • Control lever and locking lever are connected to each other by a tension spring 17.
  • Another tension spring 18 is stretched between a housing-fixed mandrel 19 and the control lever 14.
  • the electromagnet 16 is fastened in the housing with the aid of a mandrel 20.
  • the continuous housing bore 25 serves to carry out a square mandrel, which is firmly connected with a handle.
  • the control slide 13 according to FIG. 5 has a long slot 13a into which a guide cuboid of the housing protrudes.
  • a mandrel 13b reaches downwards through a housing slot into the bolt 6.
  • a control pin 13c lies in front of one of the oblique control surfaces 14d of the control lever 14.
  • a riveted touring pin 13d acts on the locking lever 15.
  • control lever 14 is shown. It has a bore 14a on the right, which is used for mounting on a mandrel 21 fixed to the housing. In the middle there is a mandrel 14b on which the locking lever 15 is pivotally mounted.
  • Another mandrel 14c serves as a stop for the locking lever 15.
  • the locking lever 15 is shown. Its most important features are the locking lug 15a at the right end, the bearing bore 15b in the middle and the magnet armature 15c at the left end.
  • Parts 13-16 work together as follows: When the bolt 6 is extended, the tour pin 13d stands in front of the right flank of the locking lug 15a. If one tries to push the latch back with the handle, the mandrel 13c pushes up the control lever 14 and the locking lever 15 when the magnet is de-energized, the tour pin 13d abutting the locking lug 15a. If there is a current supply during the opening attempt, the armature 15c is held. The control pin 13c pushes the control lever 14 up and takes the right end of the locking lever 15 with it via the pin 15c. The locking lug 15a rises and the tour pin 13d can move to the left with the bolt 6. In the end position, the tour pin 13d is behind the left flank of the locking nose 15a.
  • the mandrel 13c presses the control lever 14 and the locking lever 15 upwards, after a control movement of 2-3 mm, the tour pin 13d hits the left flank of the locking lug 15a. The bolt remains blocked. If the armature 15c is held magnetically, the control pin 13c with the control lever 14 also presses the locking lug 15a of the locking lever 15 upwards. The latch 6 can travel its full way and the security container is closed.
  • the decisive advantage of this control device is that the armature is fed to the magnet yoke by external forces and that the magnet only has to exert the low holding force. Because no lifting work is required, the magnet can be very small and its power consumption can be kept so low that the lock is supplied with a dry battery for several years. Preferably be Lithium batteries are used here, which makes the maintenance intervals even longer.
  • the locking mechanism for a double-bit key indicated in FIGS. 1 and 2 has an auxiliary bolt 22 which is partially visible in FIG. 4 and which bears a projection 22a.
  • the auxiliary bolt maintains the drawn rest position. If one inserts the emergency key into the keyhole and closes it, the auxiliary bolt 22 moves with the projection 22a to the left. It then lies in front of the control cam 15d of the locking lever 15. If the handle is actuated now, the same effect occurs as when the magnet 16 is energized: the locking lug 15a is pivoted upward and the bolt 6 can be moved in and out as desired . The key remains trapped until the door is locked. This ensures that the user does not accidentally remove the key without having locked the cabinet.
  • a lever 23 is mounted in the recess 1b of the lock housing (FIG. 4), the scanning lug of which engages in a recess in the bolt 6.
  • the lever is mounted on the housing mandrel 26 and actuates a microswitch 24, the pulses of which can be registered.
  • the auxiliary bolt 22 can also be monitored in order to indicate to the authorized user of the safe whether the emergency key has been used.
  • the slide switch 27 shown in Fig. 8 is used, which is slidably mounted under the levers 13, 14, 15. Its oblique control surface 27a then lies in front of the left end of the auxiliary bolt 22.
  • the auxiliary bolt 22 moves to the left and in doing so presses the slide 27 downward, which actuates a microswitch (not shown).
  • the signal of this microswitch is stored in the electronics and activated the next time the code is entered, so that the authorized user can be informed by an acoustic signal.
  • the lock system described which is user-friendly and makes it difficult to operate it incorrectly, can be used to great advantage in hotel room safes because the users change there very frequently. But it can also be used for office safes or in the banking sector.
