Definitions

  • the invention relates to a key depot for depositing a master key (object or access key, etc.), in particular for office buildings or the like, which can be locked with a depot key.
  • a master key object or access key, etc.
  • Key depots of this type are known and are often used where a certain group of people is to be granted access to buildings or factory facilities outside of normal opening hours. These can be the police, fire service, maintenance and cleaning staff, etc.
  • the handing over of corresponding master keys would have the disadvantage that access by this group of people would be possible in an uncontrolled manner and that if such a key were lost, the locking system would have to be completely replaced, which entails considerable costs.
  • a master key is kept in a lockable key depot, which is accessible to the group of people named after handing over a deposit key.
  • a loss of the deposit key generally requires only an exchange of the depot cylinder, which is much cheaper.
  • control and, if necessary, blocking access to the master key is possible by means of additional electronic devices.
  • a "safe for storing object keys” is disclosed, which is essentially characterized in that an alarm is always triggered when the object key is removed. In the event of a fire or the like If necessary, the police should take out the key be notified so that they can assume an "authorized removal” despite the alarm being triggered.
  • US Pat. No. 4,967,576 relates to a security container with a chamber which can be closed by a door and which is locked with a bolt.
  • the bolt is operated by an electromagnet.
  • the invention is therefore based on the object of creating a key depot of the type mentioned at the outset, in which an even substantially higher security standard and almost absolute manipulation security are achieved in a simple and interference-free manner.
  • This object is achieved in the above-mentioned key depot according to claim 1 in that it has a first lock cylinder (e.g. profile half cylinder) which can be actuated with the master key and which acts on a locking device which blocks the key depot from being closed when the master key is removed in order to identify the master key.
  • a first lock cylinder e.g. profile half cylinder
  • This solution has the advantage that, on the one hand, the master key can be identified in a reliable manner by mechanical means. Since closing the key deposit generally with a flap, a lock insert or the like. is carried out, it can also be seen from a simple visual inspection from the outside that the correct key or key is not in the depot, since in this case locking is blocked, i.e. is not possible and the deposit is therefore open.
  • a lock that can be inserted into the depot and locked with the depot key is provided.
  • a second commercially available locking cylinder e.g. profile half cylinder
  • profile half cylinder that can be replaced in the lock
  • the master key can preferably only be removed when the first locking cylinder is in a first rotational position (key withdrawal position), the first locking cylinder only releases the locking device in a second rotational position so that the depot can be closed.
  • the locking device can be formed by a slide which is displaceable in the key depot and which blocks closing of the key depot in a first sliding position and releases it in a second sliding position.
  • the slide is preferably formed by an insert axially guided in the key depot, in which the first locking cylinder is installed.
  • the slide cannot be moved into the second sliding position, in which the key depot can be closed, when the first locking cylinder is in the first rotational position (key withdrawal position).
  • a spring is preferably provided which biases the slide into the first sliding position and moves it when the closure is opened.
  • the master key can be locked with e.g. over a chain or similar be connected so that the closure also serves as a "key ring" and the risk of accidental loss is significantly reduced.
  • the key depot preferably has a substantially cylindrical housing, e.g. made of stainless steel with a cover and can be built into masonry or the like. admitted and secured there taking into account the relevant VdS (Association of Property Insurers) guidelines.
  • VdS Association of Property Insurers
  • a slide lock is provided which can be released to remove the slide from the depot when it is in the first sliding position.
  • the slide lock can be formed by an axially extending groove in the slide, a guide rail running in the groove, a spring element continuing the guide rail in the axial direction, and by a flattening of the slide which is offset in the circumferential direction with respect to the groove.
  • the slide can be pivoted in the first sliding position after the spring element has been pressed in in such a way that the stop and the flattening face each other and the slide can be pulled out of the housing past the stop.
  • the spring element is also preferably only by means of a specially adapted, key-like adapter or the like. impressible.
  • the first locking cylinder can be screwed to the slide and can be exchanged after the slide has been removed from the depot, so that another master key, e.g. can be deposited when the locking system in question is replaced without having to completely replace the key depot.
  • the slide is preferably guided in an aluminum sleeve integrated in the housing.
  • the aluminum sleeve can be connected to the housing by means of screws and can be removed from the depot after the slide has been removed.
  • All operating states of the key depot can be monitored by electronic condition monitoring and, if necessary, also influenced, i.e. be blocked or released.
  • the condition monitoring can have, for example, the following assemblies: a first device for detecting a closed or opened state of the key deposit when the master key is present, a second device for detecting an opened state of the key deposit when the key is removed
  • a third device with which an insertion of the adapter and / or a release of the slide lock is signaled, a fourth device for electromagnetic locking of the lock of the key depot and for time-dependent detection and release or blocking of the opening of the depot, and a fifth electronic device to detect a removal of the sleeve or violent attempts to pull it out.
  • the first to fifth devices are preferably constructed in a modular manner and integrated (replaceable) in the aluminum sleeve.
  • microswitches which are inexpensive and very reliable.
  • the slider can also be designed such that a key package with two to five cylinder keys (master keys) to be deposited can be received, although only one or no cylinder keys will then be identifiable for reasons of space.
  • a particular advantage of the invention is that the key depot can also be used with minor changes as a partner lock with two access keys, the depot key being the first access key and the master key being the second access key, and unlocking the partner lock by opening the depot with the first access key and by actuating the first locking cylinder with the second access key.
  • Locking elements for a door to be locked (for example a safe door) are unlocked with the first locking cylinder so that this door is now opened can be. Locking takes place in a corresponding manner in reverse by actuating the first locking cylinder and then closing the depot.
  • Figure 1 shows the key depot in the closed state. It has a stainless steel housing 1 which is flush with a masonry 3 on the outer access side with a housing cover 2.
  • the housing 1 is provided on its rear side with a threaded bore 4 for receiving anchoring elements, securing against pulling out, etc.
  • Inside the housing there is an aluminum sleeve 5 which is detachably connected to the housing 1 by means of a screw connection 6.
  • the housing 1 can be closed from the outside with a closure 7.
  • the closure 7 is inserted into the housing 1 in such a way that its closure panel 8 (FIG. 2) lies flush with the housing panel 2 and is closed with a lock 9, which can be, for example, a profile half cylinder (second locking cylinder) (see FIG. 2) .
  • a lock 9 which can be, for example, a profile half cylinder (second locking cylinder) (see FIG. 2) .
  • a locking lug 10 bears against a stop 11, so that the closure 7 cannot be pulled outwards.
  • an electromagnetic locking device 12 is provided with which a current flow Lock pin 13 is guided in the path of movement of the locking lug 10. In the state shown in FIG. 3, which can be activated, for example, by a timer, the depot is not accessible even with a depot key.
  • first locking cylinder 14 Inside the sleeve 5 there is a first locking cylinder 14, in which a master key 15 to be deposited is inserted, with which the first locking cylinder 14 can be actuated.
  • the first locking cylinder 14 is interchangeably arranged in a slide 16 which is designed as an insert and which is guided so as to be axially movable within the sleeve 5 and by means of a spring 17 from a second sliding position shown in FIG. 1 in the direction of a first sliding position (here to the left), i.e. is biased or pressed against the closure 7.
  • a locking rail 19 extending in the axial direction (see FIG. 6) is provided for a cylinder lug 18 of the first locking cylinder 14 and for the slide 16 the stop 11, which thus has a double function.
  • the lock 7 must first be unlocked with a depot key and removed from the depot.
  • the master key 15 is then accessible.
  • the slide 16 is moved by the spring 17 into the first (left) sliding position, and is now in contact with the stop 11.
  • the first locking cylinder 14 and thus also the master key 15 still assume a second rotational position. In this position, the master key 15 cannot be removed.
  • the depot could be closed again, i.e. the locking device designed as a slide 16 is released.
  • the master key 15 To remove the master key 15, it must first be turned into the first rotational position (key withdrawal position). This is only possible when the slider 16 is in the first (left) sliding position, since previously the first locking cylinder 14 and thus also the master key 15 rotate the locking rail 19 is prevented, against which the cylinder nose 18 rests or next to which the cylinder nose 18 is guided during the displacement of the slide 16 until the slide 16 is in the first sliding position in which it rests on the stop 11.
  • the master key 15 can then be turned to the first rotational position and then removed.
  • the cylinder lug 18 pivots in front of the barrier 19, i.e. in front of its (outer) end face 19 'opposite the depot opening and now prevents the slider 16 from moving axially back into the second sliding position.
  • the depot cannot be closed, since the slide 16 now occupies at least part of the depot opening into which the closure 7 must be inserted to close the depot.
  • the master key 15 If the master key 15 is to be placed in the depot again, it must be inserted into the first locking cylinder 14 and turned into the second rotary position. As a result, the cylinder lug 18 pivots away from the end face 19 'of the barrier 19 so that the locking device is now released and the slide 16 can be moved into the second sliding position. By inserting the closure 7, the slide 16 can now be moved against the force of the spring 17 into the second (right) sliding position. The lock 9 (second locking cylinder) of the lock 7 is then locked by turning the depot key (the locking lug 10 is pivoted behind the stop 11, see FIG. 3) and the depot is closed.
  • the fourth device for condition monitoring which has the electromagnetic locking device 12, has already been mentioned at the beginning, with which the depot can be temporarily blocked against any access, for example with the aid of a timer.
  • the key depot according to the invention can be supplemented with further electronic status monitors.
  • at least two microswitches are preferably provided:
  • a first microswitch 21 is automatically activated when the depot is opened, i.e. actuated by removing the closure 7 when the slide 16 is moved by the spring 17 into the first sliding position.
  • a second microswitch 22 is actuated by the cylinder lug 18 when the master key 15 is turned into the first rotational position in which it can be removed.
  • the first and second microswitches 21, 22 each form part of the above-mentioned first and second condition monitoring devices, with which detection and forwarding and signaling of the switch states to the outside, e.g. in a control room, to an alarm system or similar he follows.
  • They are preferably designed as modular electronic assemblies, which are arranged on the aluminum sleeve 5 in such a way that they can be easily replaced after the sleeve has been removed from the housing 1.
  • two plug / socket strips 25 are provided, the contacts of which can come loose when the sleeve 5 is pulled out of the housing 1 and at the same time give an alarm signal.
  • the slide 16 For maintenance work and in the case in which the sleeve 5 is to be removed, the slide 16 must first be removed. To do this, a slide lock must be released using an adapter.
  • the slide lock is shown in particular in FIG. 6 and is a guide rail 30 in the axial direction due to an axially extending groove 31 in the slider 16, a likewise axially extending and arranged on the inside of the sleeve guide rail 30 which runs in the groove 31 spring element 33 continuing to the outside (for example a narrow leaf spring or the like, see also FIG. 1), and a flat surface 32 is formed on the circumference of the slide 16.
  • the groove 31 is of course narrower than the stop 11, since otherwise in the first Sliding position the axial further movement of the shooter to the outside would not be blocked.
  • the flattening 32 is designed in the radial direction so that the stop - when the flattening 32 and the stop 11 lie opposite one another - is completely absorbed by the latter.
  • the flattening 32 extends in the axial direction over the entire length of the slide and is offset in the circumferential direction by approximately 90 ° with respect to the groove 31.
  • the axial length of the guide rail 30 is dimensioned such that in the first (left) sliding position only the spring element 33 lies in the groove 31. After the spring element 33 has been pressed in, the slider 16 can thus be pivoted by approximately 90 ° by means of an inserted adapter, namely counterclockwise according to FIG. 6. This has the consequence that the flattening 32 is now opposite the stop 11, so that the slide 16 is no longer blocked by it in the axially outward direction and can therefore be pulled out of the housing 1.
  • a third microswitch 23 (see FIG. 4) can be provided, which signals the introduction of the adapter or an indentation of the spring element 33 via the third condition monitoring device.
  • the screw connection 6 After removing the slide, the screw connection 6 is accessible, after loosening the sleeve 5 can be removed.
  • the key depot according to the invention can also be used to protect against tampering at its lock 7 with a core protection insert, anti-drilling pins or the like. Barring obstacles and a vandalism lock.
  • the depot is also preferably installed in the wall with a tensile connection to the inside of the building.
  • a fourth microswitch 24 (see FIG. 5) and / or a strain gauge with which an alarm system can be provided can be provided for the detection of pull-out and break-open attempts is activated.
  • This fourth microswitch 24 is part of the fifth device for condition monitoring and can be triggered when the sleeve 5 is removed as described above or by force as a result of attempts to pull it out against the force of a plate spring assembly 20 slightly, ie by about 1 to 2.5 mm in the axial direction is moved outside.
  • heating and other signaling devices can also be installed or retrofitted on a modular basis.
