Definitions

  • the invention relates to a secondary lock of a lock device with a main lock and one or more secondary locks for burglar-resistant doors.
  • Lock devices with multi-point locking are known, which are used for doors or the like, to which increased security demands are made. Such doors can be bullet-proof, in particular they are designed to be burglar-resistant.
  • the multi-point locking system is primarily intended to prevent the door from being easily opened in corner areas using crowbars or the like.
  • additional locks with secondary locks can be provided at such weak points, which are also actuated by a main lock in a known arrangement if the targeted locking or unlocking is initiated by actuating the lock and lock handle.
  • Locks the position of which can be recognized by a potential burglar when the door leaf is closed due to the latch handle arrangement, key insertion or profile cylinder lock, can, despite extensive efforts to make them secure, by skilled hand or by brute force, for example firearms, or by appropriately skillful manipulation of the Often put the lock mechanism out of operation in a relatively short time. If mechanically controlled further locking points or secondary locks are available from such a lock, these can often be opened with the main lock which has been put out of operation. It is then not necessary to put the other locking points or secondary locks, the installation position of which is not safe and easily ascertainable when the door is closed, out of operation by violent intervention at their installation location. It would thus be sufficient for the unauthorized, more or less violent removal of the locking function of the main lock to also remove the locking function of the additional locking points or secondary locks.
  • a door with a locking device of the type mentioned is known from US-A 3 771 339.
  • a combination lock is provided, which is located spatially close above the handle-operated main lock and is fixed to the lock housing with respect to the locking part.
  • the combination lock is accessible from the outside and can thus be located, it is located in the vicinity of the main lock in such a way that the blocking function of the combination lock can also be eliminated if it is violently destroyed.
  • the invention has for its object to make a burglar-resistant and possibly also bullet-resistant door so that even when the main lock or the main locking point is switched off, the secondary locks or secondary locking points cannot be transferred from the decommissioned main lock to their unlocked position.
  • an additional locking function is ensured independently of the function of the main lock or the main locking point, which can be localized by its actuating devices which are visible to the permitted user.
  • This is achieved by an additional locking mechanism, which is independent of the main lock and its operation.
  • the function of the secondary locking points or secondary locks is thus independent of the normal actuation of the main lock in an authorized or unauthorized manner. After the unauthorized decommissioning of the main lock, the door cannot be opened.
  • the locking mechanism provided according to the invention which is arranged outside the localizable impairment area of the main lock, can be actuated in various ways.
  • the actuation of the locking mechanism is carried out in electrical control.
  • the actuating device can be arranged in a correspondingly hidden manner and additionally subject to a coding that is only known to the authorized person.
  • a suitable switching device can be provided at a suitable point, in particular in such a way that a certain code is provided in the manner of a combination lock or the like, in such a way that this control device for the locking mechanism is not actuated from the main lock. So even if the control device for the lock is visible to unauthorized persons, knowledge of a certain code must be present in order to actuate the lock.
  • a keyboard based on numbers, letters or the like of freely selectable symbols, which require knowledge of an opening code, is suitable here in order to transfer the secondary lock from the closed position into the open position.
  • Such a coded control device is generally to be installed outside the door, so that targeted use of force is ineffective.
  • the electromagnetically designed locking mechanism consists of an electromagnet with a movable armature, which acts directly or indirectly as a locking element in the movement path between the locking point and the unlocking point of a locking element of the lock device in the area outside of the main lock located locking point or a locking member is arranged engaging.
  • a so-called plunger coil magnet is suitable for this.
  • the burglar-resistant door leaf 1 in FIG. 1 is shown in outline without a frame with the lock device in the closed position.
  • the lock device consists of a main lock 2 and an upper and a lower secondary lock 3, each of which is arranged in the corner areas of the door leaf that swing open in the course of the opening movement.
  • the door leaf is pivoted about hinges 4.
  • bolts are located in a manner not shown and known in the door leaf, which emerge from the front side and engage in bores in the closed state of the door leaf, which are provided in the frame side member. In this way - for example with a crowbar - the door leaf cannot be pried open without particular difficulty.
  • FIG. 2 and 3 show a secondary lock, for example that in the lower corner area of the door leaf 1 according to FIG. 1.
  • One, two or even more such secondary locks can be provided. It is also possible to mount the locking mechanism, which will be discussed later, in the area of the main lock, for example in the trap area thereof.
  • the locks can be provided with several bolts, which can be swivel bolts or also longitudinally displaceable bolts.
  • the secondary locks are operated in normal operation from the main lock with the aid of mechanical movement transmission means, as is generally known.
  • the secondary lock according to FIGS. 3 and 3, on which the arrangement of the locking mechanism is illustrated, has a lock shield 5 on which a housing part 6 is fixed by means of cranked tabs 7, which can be done by welding, screwing or the like.
  • the lock housing is formed in two parts, of which only the lower housing part 6 is shown in Fig.2 2. In the sectional view according to FIG. 3, the upper housing part is also indicated.
  • an actuating part 8 is guided so as to be longitudinally displaceable in the longitudinal direction of the lock shield 5.
  • the lock of the lock is designed as a pivot bolt 9 and is mounted on the housing or the housing part 6 such that it can be rotated about a pivot axis 10.
  • the actuating part 8 is U-shaped and accommodates the swivel bolt 9 between its two legs, which are formed over a wide area parallel to the swivel plane of the swivel bolt 9.
  • the pivot axis 10 extends through elongated holes 12, which are formed in alignment in the two legs in the direction of the pivot axis 10.
  • the pivot axis 10 is held at its two ends on the housing, specifically fixed to the housing part 6 and accommodated in the housing cover 17.
  • a second section of the longitudinal slide guide tion of the actuating part 8 is formed by a further pair of elongated holes 13, which are provided in the direction of displacement to the elongated holes 12 to the web 15 of the U-shaped actuating part 8 offset in the legs thereof, in alignment in the axial direction of a housing screw bolt 14, seen in parallel is aligned to the pivot axis 10 and extends through the pair of elongated holes 13.
  • the elongated holes 12 and 13 extend in the longitudinal displacement direction of the actuating part 8 by at least the length required for the actuating displacement path relative to the pivot axis 10 or the screw bolt 14 for rotating the pivot bolt 9 between its locking and unlocking position.
  • the housing screw bolt 14, like another fastened at a spaced-apart location on the housing part 6 and aligned parallel thereto, is provided with an internal thread into which screws passed through the housing cover 17 at corresponding points can be screwed in order to close the housing.
  • a threaded end of a lock operating rod 15 is guided and fixed by screwing, the other ends, not shown, are connected to the locking mechanism of the main lock 2, in a known manner, not shown to transmit the locking or unlocking movement of the main lock synchronously to the secondary lock.
  • the rod 16 thus moves the actuating part 8 back and forth depending on the actuation of the main lock 2, as a result of which the pivot bolt 9 is rotated between its locking position shown in FIG. 2 and its unlocking position, in which the pivot bolt through a correspondingly dimensioned slot opening 18 into the Interior of the housing is pivoted.
  • Such a secondary lock is subject to the risk of being able to be opened in the event of destruction or unauthorized actuation of the main lock.
  • the or each of the secondary locks 3 provided is provided with a locking mechanism, designated overall by 20, which has a locking element, generally identified by 21, which can be remotely displaced between a closed and an open position.
  • a locking mechanism designated overall by 20, which has a locking element, generally identified by 21, which can be remotely displaced between a closed and an open position.
  • the locking member 21 blocks the longitudinal movement of the actuating member 8 from the locking position of the pivot bolt 9 in its unlocking position, regardless of a force exerted on the rod 16, so that the unlocking of the secondary lock 3 depends only on the remote control of the locking mechanism 20.
  • the locking mechanism 20 is designed as an electromagnet 22 with a plunger armature 23, one end of which serves as a locking member 21.
  • the electromagnet 22 formed with a hollow core receiving the rod-shaped plunger armature 23 is fastened to a magnet holder 24 which is fixed to the housing in a manner not shown in such a way that the plunger armature 23 is oriented approximately perpendicular to the longitudinal displacement direction of the actuating part 8 with regard to its direction of movement.
  • the plunger armature 23 extends through the pierced core of the electromagnet 22 and ends in its end forming the locking member 21 in a tapered shaft part 26, onto which a helical spring 25 is pushed.
  • the immersion armature 23 assumes this displacement position when the coil or the electromagnet 22 is not energized.
  • the plunger armature When the coil of the electromagnet 22 is appropriately supplied with an excitation current, the plunger armature is moved against the force of the optionally prestressed spring 25 into a displacement position in which its end forming the blocking member 21 is located outside the engagement in the space between the legs of the actuating part 8.
  • This method of operation of a moving coil magnet is known and requires no further explanation here.
  • the tapered shaft part 26 is guided in a longitudinally displaceable manner in a bore 27 of the offset 19 of the magnet holder 24.
  • the electromagnet 22 When the electromagnet 22 is not energized and thus, under the force of the spring 25, the plunger 23 displaced into the space between the legs of the actuating part 8 blocks its end serving as a locking member 21, the path of a locking stop 28 which is provided between the legs and is formed integrally therewith seeks to move in the longitudinal displacement direction of the actuating part 8 upon transfer into the unlocking position of the pivot bolt 9.
  • the electromagnet 22 When the electromagnet 22 is not energized, such a transfer of the secondary lock from the locking position into the unlocking position cannot take place, even if the main lock is destroyed or opened without authorization.
  • the electromagnet 22 is energized, the plunger armature 23 is drawn into the magnet, so that its end, which acts as a blocking member 21, is pulled away from the actuating part 8 and releases the path of the blocking stop 28.
  • the secondary lock can be locked and unlocked synchronously from the main lock.
  • the connecting wires, not shown, the Coil of the electromagnet 22 are supplied to a control device, also not shown, which determines the excitation of the coil as a function of a switch located outside the main lock or the door.
  • a control device also not shown, which determines the excitation of the coil as a function of a switch located outside the main lock or the door.
  • This can be done by a hidden simple switch or preferably by a combination lock-like coding device, for example in the form of a keypad, which allows the input of a specific number or letter code which is checked and evaluated according to value and / or sequence.
  • Wireless coding can also be entered here, as is known in many ways.
  • the secondary lock can therefore be locked independently of the mechanical actuation of the main lock by an electronic combination lock.
  • the housing of the secondary lock is, in a known manner, let into the front of the door leaf in such a way that it does not appear from the outside when the door is closed and therefore cannot be located. A deliberate intervention by force on the secondary lock itself is thus prevented or made more difficult by locating it.
  • a special advantage of equipping with the locking mechanism can be seen in the possibility of retrofitting.
  • a locking stop is required, which in the present case can easily be provided by welding or the like between the legs of the actuating member.
  • corresponding locking stops can also be retrofitted at another suitable location.
