Definitions

  • the invention relates to an electromagnetically actuated lock, in particular for security containers, with a bolt operated by a handle and an electromagnet used as a holding magnet, which locks or releases the bolt via control and blocking elements.
  • Such a lock has become known from European Patent 0427188.
  • the electromagnetically controlled security container lock described there has an electromagnet fastened in the housing, which is opposed by an armature mounted on a locking lever.
  • the intricately shaped locking lever is coupled via a bearing pin, control cams and a spring to a control lever that has a touring channel.
  • a locking slide is provided which carries a touring pin which engages in the control lever.
  • the blocking or release by swiveling movements requires an exact interaction of holding magnetic forces, control cams, control pins, bearing pins, springs and tour pin.
  • the parts may hardly have any bearing play or wear, otherwise they will fail due to canting.
  • European patent 0228027 also relates to an electromagnetically controlled security lock with a housing, in the front opening of which a bank locking mechanism is housed in addition to a customer locking mechanism.
  • An electromagnet is accommodated in a recess on the back of the housing.
  • a locking lever and a control lever are arranged under the main bolt, which is relatively difficult to access.
  • the locking lever carries a magnet armature, which faces the yoke of said electromagnet.
  • the interaction of the magnet, control lever, locking lever and tour pin is rather confusing, whereby tight manufacturing tolerances are required to ensure permanent functionality.
  • the invention has for its object to provide a lock with the features mentioned in the introduction, which requires only a few, easily manufactured individual parts, which has a low power consumption and which is characterized by particular reliability and durability.
  • the handle moves a spool in addition to the bolt, which is coupled via an electromagnet with a locking slide, in the tour channel of the touring pin of the bolt.
  • control slide, the cross slide and the locking slide are matched to one another with the magnetic parts in such a way that in the idle state the magnetic armature bears against the yoke with the coil.
  • the cross slide is raised, taking the blocking slide with it when a current pulse is present.
  • the magnet is de-energized, the cross slide moves away from the locking slide so that it remains in the locked position.
  • the electromagnet does not have to do any lifting work in any case, so that a very small magnet with a very low excitation current is sufficient.
  • the lock will be designed so that only unlocking is dependent on the presence of an electrical pulse.
  • While in the basic version of the tour channel is designed so that the tour pin rests in it when the bolt is open, another embodiment of the invention provides that the tour pin exits the tour channel at the end of its opening path so that the locking slide can fall again into the locking position.
  • a guard locking package is additionally installed.
  • the handle is replaced, for example, by a double-bit key, so that parts of the key bit drive both the bolt and the control slide.
  • the term "handle” is thus to be understood in such a general way that it also includes double-bit keys or cylinder keys. It is crucial that the torque for the movement of the controls and the latch is built up by hand and thus the long-term power supply of the lock of a small and inexpensive Battery can be left.
  • Fig. 1 denotes the lock housing, which preferably consists of die casting or is injection molded from fiber-reinforced thermoplastic. Screw holes 1a, 1b, 1c, 1d are provided at the four corners of the cuboid housing.
  • the bolt 2 is slidably mounted in the left half of the housing 1, the bolt 2 is slidably mounted.
  • the bolt 2 has a control recess 2a into which a swivel 3 is immersed, which is actuated by a handle (not shown) via a square hole 3a.
  • An arm 2b of the bolt 2 reaching to the right carries a cuboid tour pin 2c.
  • a spool 4 is slidably mounted. It moves in the same direction as the bolt 2 and is driven by a pin 3b on the swivel 3. This mandrel dips into an elongated hole 4a.
  • the control slide 4 has an elongated control cam 4b which takes a cross slide 5 with it.
  • the slide carries a mandrel 5a which scans the control curve 4b.
  • a light coil spring 8 presses the slide 5 down and the mandrel 5a against the control cam 4b.
  • a locking slide 6 is mounted below the cross slide 5. Both slides lie in a recess le of the housing. Their movements are limited by stop surfaces lel and 1e2.
  • the locking slide 6 has a tour channel 6a shown with broken lines, into which the tour pin 2c can enter if it is positioned correctly.
  • an electromagnet 7 is attached, which is opposed by an armature 7a on the cross slide 5.
  • Fig. 1 shows all parts in the locking position.
  • the locking slide 6 remains in the rest position and the tour pin 2c abuts against the surface of the locking slide 6. After a short control travel, the rotary movement of the handle is limited and the bolt 2 remains in the extended position.
  • Fig. 3 shows the opening process, which is initiated when the magnet 7 is excited and then the handle is moved.
  • the electromagnet 7 holds the armature 7a so that the cross slide 5 takes the locking slide 6 with it.
  • the locking slide 6 is raised so far that its tour channel 6a is opposite the tour pin 2c.
  • Fig. 6 shows the closing of the safe when applying a current pulse.
  • the locking slide 6 is coupled to the cross slide 5, the tour pin 2c passes through the tour channel 6a and the latch 2 can be fully extended. In this end position, the tour pin 2c emerges from the tour channel 6a, the locking slide 6 falls down and the container is securely closed.
  • the state of the lock then corresponds again to FIG. 1 .
  • the control elements are shown enlarged in FIG. 7 .
  • the coil spring 8 ensures that the mandrel 5a rests on the control cam 4a.
  • a second, very light coil spring 9 is located between the locking slide 6 and the cross slide 5.
  • the slides 5 and 6 are mounted easily in the recess 1e of the housing 1. The movement is limited upwards by the stop surface 1e1, and downwards by the surface 1e2.
  • Fig. 8 shows a longitudinal section through the novel lock.
  • the latch 2 with the arm 2b, the tour pin 2c, the cross slide 5 and the coil springs 8 and 9.
  • the functional parts in the housing 1 are protected by a housing cover 10.
  • the vortex 3 is guided at the bottom of the housing base and at the top in the housing cover 10.
  • Fig. 9 is a cross section through the castle.
  • the latch 2 is mounted in the housing 1.
  • In the middle is the vortex 3 with the mandrel 3b which touches the control slide 4.
  • Fig. 10 the bolt 2 is shown with the control recess 2a, the arm 2b and the tour pin 2c.
  • the control recess 2a is designed so that the vortex has a certain idle. In this phase of movement, the control slide queries the actuation status of the lock. If the magnet is excited, the opening or closing process can be carried out.
  • the handle is stopped after a short angular movement.
  • the force for the control processes is deliberately applied via the handle so that the electromagnet does not have to do any lifting work. You can therefore get by with a very small holding current that can easily be applied from a standardized multi-cell battery.
  • the battery can be easily accessible in a compartment 1f of the housing.
  • FIG. 12 shows the cross slide 5, which has a depression for the magnet armature 7a at the lower edge.
  • the electromagnet 7 consisting of magnetic yoke and coil is shown in FIG. 14 , the associated armature 7a in FIG. 15.
  • 16 shows the vertebra 3 with the square hole 3a and the mandrel 3b at the end of the cantilever arm engaging in the latch 2.
  • the security container 17 shows a special shape of the locking slide 6. It has a lateral projection 6b above the tour channel 6a, which holds the tour pin in place when the bolt is withdrawn. If one installs this gate valve in the lock instead of the one shown in FIG. 13 , the security container can be locked at any time, that is to say without a coded current pulse.
  • the lock described is ideally suited to be used in valuables containers or valuables cabinets of various types.
  • the invention is not limited to the lock shown with the bolt drive via swivel and handle. You can also install a tumbler lock so that both a key and a coded current pulse are required to open it.
  • a "double-bit key” then serves as the "handle”, which both "classifies the tumblers on its" control path "and moves the control slide before a part of the key bit sets the bolt in motion.
  • the lock shown is supplemented by a double-bit locking mechanism, which is housed in a recess in the housing and serves as an emergency opening system.
  • the additional locking mechanism is only needed if the user has forgotten the code or the coding device is damaged.
  • the entire system is then designed in such a way that the manager can open it with the emergency key, but the user code must be re-entered to lock it. This prevents an unfaithful manager from opening the compartment without informing and consulting the tenant.
  • the structure of the lock housing and the bolt basically allows bascule rods to be stored in the left third of the housing, which are driven by a mandrel 11 on the bolt 2 (FIG. 10) .
  • the great advantage of the new type of magnetic mechanism is that, instead of locking and control levers with complicated control cams, it essentially requires only three slides, of which only one has a control curve. These slides, which only perform linear movements, can be easily and precisely stored in recesses in the housing. In this way, a permanently reliable and precise function is achieved with comparatively little production effort.
