EP1308586A1 - Device for a secure storage of a key - Google Patents

Abstract

A wall mounted key safe has a cylindrical metal shell buried in a wall and accessed via a lockable front panel. A fixed shaft is secured to the base of the safe and interacts with the release lock cylinder as well as with a sliding catch which allows the key safe to be opened by a master key but which retains the master key until released by a control key. This provides a simple checking system for use of particular master keys. The control key operates on a similar simple cylinder lock to release the catch.

Description

The invention relates to a device for secured Storage of a key or other item according to claim 1.

Company buildings and facilities are outside of operating hours normally secured against third party access. To in Emergencies a security service, such as the Firefighters are often given access to the secured property a so-called key depot is provided, in which the required object key is deposited.

In an emergency, the key depot can be used by the Security service opened using a master key and the object key can be removed so that the corresponding inputs of the protected object without Let the use of violence open. A security service that supervised, if necessary, several buildings and systems only one master key, with which the respective Have key deposits opened.

Requirements, planning and installation of key depots for example in the VdS guidelines for key deposits, Directive 2105 of December 1996, of the Association of Damage insurer e.V., Cologne.

Basically, the storage of keys in one Key depot an increase in risk for the associated property Is the key depot not specified accordingly Guidelines installed, operated and maintained, If applicable, a contractually stipulated one expires Insurance coverage. The security of key depots is therefore of great importance.

Key deposits are, for example, from the published patent application EP 0 688 421 A1 is known. The one described there Key depot has a wall pipe with a holder for an object key and one by a first Locking cylinder secured closure part that with with a master key. The object key, the can be removed after opening the closure part insertable into a second locking cylinder, which is connected to the first lock cylinder is coupled such that a Keys from the first or second locking cylinder only can then be removed if the associated key is in inserted the other, second or first locking cylinder has been. After inserting the master key, the Object key removed and the object opened. The object key can then be deposited and the master key can be removed.

The two locking cylinders facing away from each other are included a key carrier unit connected to the removal of the Object key are completely removed from the wall pipe got to; however always with a safety rope to the wall pipe stays connected.

Due to this special construction, a considerable manufacturing effort. The locking cylinders are to couple mechanically, resulting in an increased one hand Manufacturing effort and on the other hand a possible source of error results. The axially one behind the other Lock cylinder, which is hardly manufactured in large numbers Standard versions are available, also lead to a considerable installation depth of the key depot.

Another disadvantage of this device is that opening the key depot and thus using the Object key not due to mechanical changes is detectable. A carrier of the master key can be therefore gain access to the secured object without then its identity and intrusion is noticeable.

Furthermore, the described key depot is only used for Storage of a special key in the associated Lock cylinder is introduced.

The present invention is therefore based on the object an improved device for secure storage to create a key or other item.

In particular, an inexpensive to produce practical maintenance-free device can be created that more simply constructed and better against unauthorized manipulation is protected.

Furthermore, a device should be created that it allows to determine who opened the device.

These tasks are secured with a device Storage of a key or another solved security-relevant object, which the in Claim 1, specified features. Advantageous configurations the invention are specified in further claims.

The device according to the invention, that of the secured Storage of an object key or another Serves object, has one in a stationary mountable Wall pipe insertable, for holding the object key or of the other subject appropriate slide on introduced by means of a first locking cylinder is lockable. According to the invention is one with the Wall pipe connected or connectable locking rod provided that a first recess for receiving a Driver of the first locking cylinder and a second Recess for receiving a rotatably mounted in the insert Has pawl that while pulling out the open slot engages in the second recess and slidable therein between a first and a second Stop is held, and the one by means of a driver second lock cylinder from engagement in the second Recess is removable.

The insertable through a hole provided in the slot Locking rod is designed such that, after Engagement of the pawl in the second recess, the first Stop the full insertion of the insert and thus the engagement of the driver of the first locking cylinder in prevents the first recess and that its second stop the complete pulling out of the insert from the wall pipe prevented. Securing parts of the device by means of a safety rope, such as that in EP 0 688 421 A1 described device, is therefore not necessary.

After the pawl engages in the second recess therefore the driver of the first locking cylinder is no longer in the first recess of the locking rod is screwed in, so that the one in the first locking cylinder Master key no longer after unlocking the slot can be pulled out.

The device according to the invention has numerous advantages compared to known solutions. The device is simple constructed and with two conventional, not with each other coupled lock cylinders can be equipped so that reduced Manufacturing costs result.

In addition to the locking cylinders and the rotatable latch no moving parts are provided, so that Reduce maintenance work to a minimum and that Functionality of the device is preserved over years. The The pawl is preferably mounted eccentrically such that it each by means of gravity against the locking rod is moved. A spring for moving the pawl can therefore used, but is not necessary. A feather will possibly used if the installation of the device in any location should be possible.

Because the locking cylinders used side by side and not are arranged one behind the other, the device can also small dimensions, especially with a small installation depth are made so that they are in walls or metal beams different sizes can be easily installed.

In addition to the reduced manufacturing and maintenance costs the device in particular also various safety-related Advantages on. To open the device only the first locking cylinder can be operated. In one In an emergency, the device can therefore handle the highest Reliability can be opened quickly.

After opening the device and pulling out the The slide-in is made possible by the engagement of the Pawl limited to the locking bar. The insert leaves not completely undress and remove, but also no longer fully insert, so the first Lock cylinder, its driver on the locking rod nudges, no longer locked and therefore the master key can no longer be deducted.

Opening the device and removing the object key can therefore be easily identified. It is not possible to remove the protected object Enter the object and then the object key deposit again and lock the device. Corresponding damage risks, for example the theft of Goods or manipulation of machinery and equipment, are thus avoided.

It can also be determined with whose master key the Device was opened. By means of the device hence the key holder, the security service, the fire brigade, for example, from false suspicions protected. Anyone can have their master key Keyholders prove that the property is not his key was opened. The device therefore offers comprehensive protection for the property and the Security system involved people.

After pulling out the insert, the jack can be removed using the second locking cylinder actuated by a control key released and the master key removed. The Control key holder, for example the administrator of the protected object, is therefore, together with a holder of the or a master key, always present when the Object key deposited in the device and this is completed. Furthermore, the master key, according to Opening the device, also only in the presence of the Control person or the holder of the control key be deducted so that interference with the security system and the people responsible for it can always be identified are.

By double checking the two carriers of the main and the Control key also ensures that the correct object key is deposited in the device.

The insert, which is preferably made from a monoblock, has one the object key or the other object adapted recording space, each by pulling out of the slot is made accessible. Instead of or in addition to the object key could be, for example Data carriers are deposited, by means of which the intervention in the operation of a system is made possible.

Figure 1 shows an inventive device 1, the secure storage of an object key 4 (additional designated by O) or another object. The Device 1 has a flange 11 on the front provided wall pipe 10, which is installed in a wall 2 is. The wall pipe 10 is on the front in a known manner a lid 19 completed by means of a retaining bolt 18 is rotatably connected to the flange 11 (see also FIG 3).

The object key 4 to be kept is also shown as well as a master key 5 (additionally designated with H) and a control key 6 (additionally designated K), which for Operation of the device 1 are required.

Figure 2 shows a side section of the hollow cylindrical Wall pipe 10, the installation side through a tube sheet 13th completed and on the outside with assembly grooves 12 is provided, by means of which the wall pipe 10 in the wall 2nd is held. The tube sheet 13 is with a locking rod 20 connected, which is perpendicular to the tube sheet 13, parallel to the axis 300 one in the wall pipe 10 sliding insert 30 aligned (see Figure 5) and provided with a first and a second recess 21, 22 is. It can also be seen that the flange 1 is a for Receiving the holding bolt 18 serving opening 23.

Figure 3 shows the device 1 seen from the front with inserted slot 30, in the side by side in holes 52, 62 a first, by means of the master key 5 actuating and a second, by means of the control key 6 lock cylinders 50, 60 to be actuated are installed. Lock cylinders and their function are, for example, in Wood technology, carpenter expertise, 13th edition, PUBLISHER EUROPEAN TEACHING AIDS, Wuppertal 1987, page 419 (see image 1) described. The driver of the lock cylinder is there as Marked beard.

By a section through the insert 30 shown in FIG. 3 is the view of the driver 51, 61 of the locking cylinder 50, 60; on a pawl 36 rotatably mounted in the insert 30 as well as the intersected in the region of the first recess 21 shown and through a bore 31 in the slot 30 guided locking rod 20 exposed.

FIG. 3 also shows that the first recess 21 the locking rod 20 for the engagement of the driver 51 of first lock cylinder 50 is provided. In the shown The state of the insert 30 is therefore completely in the wall pipe 10 inserted and from the driver 51 of the first Lock cylinder 50 held. The pawl 36 rests on the Lock rod 20 and is not in engagement with this. The Driver 61 of the second locking cylinder 61, the only serves to operate the pawl 36, is located in his passive position.

Figure 4 shows the completed device 1 in one Side section. It can also be seen that the Pawl 36 rests on the locking rod 20 and not in the latter engages second recess 22. This fact is for that Closing the device 1 substantially, which only take place can when the latch 36 is raised and the insert 30 fully inserted.

The closed slot 30 can by means of the master key 5 unlocked and pulled out, after which the object key 4, as shown in FIG. 5, from an insert 30 provided receiving space 33 can be removed. If the Receiving space 33 is provided on the underside of the insert 30 and the control key 4 is provided with a retaining ring 40 is, this falls after pulling out the insert 30 below and can therefore be easily grasped.

Figure 6 shows a side section of the device 1 with the extended Insert 30. The pawl 36 is in the process of being pulled out after a short shift to the second Recess 22 fallen and is slidable between a first and a second stop 221, 222 held. The The first stop 221 is positioned such that the Access to object key 4 or another object can only take place while pulling out the insert 30, after which the pawl 36 in the second recess 22nd intervened.

The pawl 36, which is preferably designed and assembled in this way is that they are unlocked while pulling out the Insert 30 into the second by gravity Recess 22 falls, has a for engagement in the Locking rod 20 provided locking piece 361 and a with the driver 62 of the second locking cylinder 60 cooperating lever piece 362. The pawl 36 is by means of a parallel to the axis 300 of the insert 300 in a bore 35 provided shaft 35 so eccentrically stored that the released closure piece 361 each quickly tilts against the locking rod 20. Is possible also the use of a spring by means of which the pawl 36 is pressed against the locking rod 20.

The first stop 221 of the recess 22 prevents after Engagement of the pawl 36 thus the complete insertion of the Insert 30 and therefore the intervention of the driver 51 of the first locking cylinder 50 in the first recess 21. Der Master key 5 used to open device 1 was, therefore, is no longer from the first lock cylinder 50 Extendable. The second stop 222 prevents this completely withdraw the insert 30 from the wall pipe 10. The insert 30 is in the shown state of the device therefore with blocked master key 5, limited by the Stops 221, 222, axially displaceable within the wall pipe 10.

FIG. 7 shows the device 1 with the insert 30 pulled out from the beginning. As described above, the pawl 36 has the engaged second recess 22. The turning back of the Driver 51 of the first locking cylinder 50 is by the Locking rod 20 prevents the plugged into it Master key 5 is blocked.

It can therefore be easily determined that the device 1 was opened. It can also be determined with whom Master key 5 the device 1 was opened. At the same time, parts are prevented in a simple manner the device 1 can be removed. A safety rope and other associated device parts, as described in EP 0 688 421 A1 are not required.

FIGS. 7 and 8 show that the pawl 35 by rotation of the driver 61, the second Lock cylinder 60 from engagement in the second recess 22 can be freed, so that the insert 30 again fully inserted and closed or even completely can be pulled out.

The various advantages of the device according to the invention 1 were described at the beginning. In addition to the extended and improved functionality, is the simple structure with the Use of only a few moving parts is essential. The the two locking cylinders 50, 60 used are not coupled with each other and can therefore standard designs be in large quantities at a corresponding price are manufactured.

The insert 30 is preferably made of a monoblock manufactured, in which the bore 31 for receiving the Locking rod 20, the bores 52, 62 for receiving the Lock cylinder, the bore 34 for receiving the for storage the pawl 36 serving shaft 35, the space 33 for receiving the Object key 4 and a transverse recess 32 incorporated be in which the pawl 36 and the driver 51, 61 of the Lock cylinder 50, 60 can be moved.

As shown in FIG. 6, the insert 30 has one preferred configuration perpendicular to its axis 300 at least one optionally slit-shaped on the front Opening 38, which is used to insert a steel plate 39 serves by means of which the insertion of the insert 30 is prevented can be.

The insert 30 can also have more than one space 33 for receiving the object key 4 and another object exhibit. Instead of or in addition to the object key 4 for example, a data carrier could be deposited, by means of which the intervention in the operation of a plant is made possible.

As shown in FIG. 9, the insert 30 preferably has Fasteners, for example one with screws 41 mounted spring 42, by means of which the object key 4 or the further object is held in the receiving space 33 become.

The safety advantages of the device 1 were already described in detail at the beginning. To open the Device 1 only needs the first locking cylinder 50 be operated. The device is closed always in the presence of a control person, the owner of the Control key 6, so that the security Processes take place under optimal control. Even after Opening the device 1 after the occurrence of an emergency, the blocked master key 5 is removed and that Close the device again in the presence of one Control person. The device 1 therefore allows Realization of an improved security system, which requires the participation of a control person.

The device 1 according to the invention was preferred Design described and shown. Based on Teachings according to the invention are numerous other technical ones Embodiments of the device 1 described can be implemented. On the one hand there are different materials, metals or also Plastics, usable for the production of the device parts. The locking rod 20, the tube sheet 13 and the wall tube 10 can be welded together (see welding seams 120, 130 in Figure 2) or as castings.

It is also possible to install sensors or switches, by means of which, for example, the positional state of the Insert can be determined and for example in one Monitoring center of the police or fire department displayed can be. A manipulation on the device 1 would therefore trigger a message or an alarm. An installation of Due to the simple structure, the sensors solution according to the invention is particularly possible. A sensor 95, which detects the extension of the insert 30, is shown in FIG Figure 9 shown purely schematically.
