Description

Expandable drive system and system safety with drive element.

Technical field

The invention relates to a system of expandable drive and to a safety system with a system drive, which can be used especially for the door a housing, for example a distribution housing of the Telecommunications and data technique.

In many industrial and private mechanisms there is a need to protect by closing systems, not only isolated rooms, but also cabinets, housings and the like against an external and unauthorized access. Especially in the field of Telecommunications and data technology should be housed and closed cable connections and data lines, so that they can discard changes in connections by unauthorized persons This is often not enough. by providing a locking system that is operated by a key and is connected to an interlocking mechanism that, in a closed state of the closing system, prevents the opening of the housing door or similar. The keys of this kind of locking systems, as you know, they can be lost precisely with ease, so that it cannot be reliably ruled out that people, who have a unauthorized key, get access to the housing to to protect. It is also desirable, in certain cases, to detect opening processes and the people who perform the opening.

State of the art

EP 0 743 411 A2 describes a locking device, whose key shows a configured encoder as transponder In the cylindrical housing of the closing cylinder there is an actuator, a transponder reader mechanism and A power feeding mechanism. When a signal occurs positive on the transponder side moves an organ of lock, in such a way that the cylinder core is unlocked.

Document CA 2,096,380 A1 makes clear a door drive mechanism, in which an alarm is activated when opening is not done by a remote control suitable.

According to WO 96/23120, it travels with a rotating drive element, in the event that present a positive access signal, thereby a pin, which gears with an element that is attached to an interlocking, such way that the interlocking can be unlocked.

For enhanced system protection closing of a housing door is known, from document DE 43 02 835 C1, provide an interlocking device that shows for a latch, which prevents in an appropriate position the opening of a housing door, two drive phases. To unlock the latch, an operator must activate first, for example with help of a key, the first phase of actuation of the latch, in which the latch is still in a position where the opening of the housing door is prevented. In a second step it active, for example by means of an encrypted card from which the The operator must also have the second phase of drive in which, through a communications line and data, from an exchange an identification control of the user, and then remotely unlock the latch. The opening of the housing door is not in this way possible until remote unlock execution.

This known system does offer a certain improved security against unauthorized access to a housing, for example from a cable distributor. However it has the disadvantage that remote unlocking is necessary from a command center, in addition to which the corresponding lines of communications and data. Also, in this system according to the state of the art an opening is required for a socket or an opening for a reading device of cards Finally, the two phases of actuation of the latch depend on each other, and the drive must be performed necessarily in two phases in the exposed mode. In this way the system should be used as a whole, to replace a system of existing closure, and especially not suitable to complement with an additional safety function a closing system already existing, without retouching the door.

In view of these inconveniences of security systems known in the state of the art, the invention has set itself the mission of creating a system of drive and a safety system with a system of drive, having a simple structure, ensure a reliable protection against unauthorized access and that are also appropriate to extend a locking and / or interlocking system now existing.

Presentation of the invention

This mission is solved through a system of expandable drive according to claim 1. In the claim 13 describes a security system according to the invention with a drive system.

The expandable drive system according to the invention shows in detail a drive element, a code support, preferably a chip, and a reader system for Read contactless code support. The reader system can be applied in the region of the drive element or the interlocking, with which the element of drive according to the invention. There is also a unit of assessment, in which codes are stored access authorization, and that is linked to the reader system and that value information stored in the code carrier, compare it with access authorization codes and, if the result is positive, unlock a locking mechanism. The aforementioned mechanism of lock is applied in such a way in the region of the element of drive or can be applied in the region of the element of drive or interlocking which, in a locked position, blocks a movement of the drive element and / or the interlocking

According to the invention, the safety function additional is decoupled in this way, in the form of the mechanism of blocking, interlocking and / or closing system. In consequently the drive system according to the invention can be combined without further interlocking and / or a system of closure, which already exists in the door of a housing. A mechanism existing can therefore be extended, in a slightly complex way, in a safety function, by means of which the drive element expandable according to the invention replaces an element of existing drive without an additional locking mechanism. The expandable drive element according to the invention shows here the same connections with the mechanisms in the interlocking existing, that the drive element without function of security, in such a way that no work of complex transformation in the door or interlocking.

In detail, the operation of a system of Existing closure in certain circumstances is done with help of a key or similar regardless of the actuation of the locking mechanism, which represents a component of the element of expandable drive according to the invention. As mentioned, the locking mechanism locks, with the corresponding application in the region of the drive element and / or the interlocking, a movement of drive element or interlocking e this prevents, in the locked position, an actuation of the corresponding interlocking mechanism, regardless of unlocking of the mentioned systems by means of a key correspondent.

By means of which, according to the invention, as drive system component is provided a unit of valuation, which does not necessarily have to be linked to a central station, with a constructively comparable complexity reduced you can check the authorization of access. Through this provision to some extent decentralized of the valuation unit, lines of communications or data to a central station. Also, because of the simple structure of the drive element according to the invention, from few isolated elements, can be extended an existing interlocking at any time with the element of drive described.

For described item code support In accordance with the invention, a chip is preferred. Without However, those elements whose appropriate stored information can be detected by a reader system suitable. Here you can especially think that the reader system create a permanent magnetic field, from which the chip is activated Other code support. This activation of code support influences the magnetic field of the reader system, and this Magnetic field modification generated by the reader system is Registered by the reader system. The reading system can deduce the code stored in the code holder of the class of modification, so that the valuation unit can compare with the code stored in the code carrier. Of this mode is possible, in a decentralized way and with a complexity reduced, a control to protect a closing system or interlocking

The drive system according to the The invention also shows its own closing system. In this way In this way, a drive element is replaced existing, together with the closing system configured in it, by the drive element according to the invention with a locking system and locking mechanism according to the invention. The locking system is preferably configured as a lock profile cylinder, profiled cylinder lock or as lock with disk guard. In this form of execution is advantageous that the locking mechanism of the drive element according to the invention, prevent a turning in the locked position of the closing system itself. However, the locking mechanism it can also be applied in such a way that it blocks a drive of the drive element.

Also the locking mechanism can be operated electromechanically It is specially planned to configure the Bipolar and electromechanically operable locking mechanism, so that it only needs one connection for the connection process. applied energy This measure can be increased conveniently the efficiency of the conforming drive element to the invention.

In the cited embodiments the drive element expandable is advantageously advantageous to replace the cited drive elements, which until now were used without the additional locking mechanism according to the invention, and of this way complement the closing and interlocking system of a Corresponding housing with additional protection. How has it cited, the drive element according to the invention shows, in the cited forms of execution, the same connections with the existing construction parts in the housing door, in such a way that without complex transformation work, it is done expansion possible with a drive element with mechanism lock

For the reader system it is preferred that it be applied in the region of a handle of the drive element. By means of the possibility of having the reader system to read the support of code in this region, the ease of handling is further increased of the drive element applied in the region of a existing interlocking, since within the framework of the locking system is possible by means of a key, in certain measured with the same movement, the approach of the support of code to the reader system to detect the information stored

For the constructive configuration of the mechanism blocking has proved advantageous to provide this, eg, with a cylindrical bolt and / or a hook.

For the locking mechanism it is further preferred that this is executed in such a way, that in case of a fall of current pass to a defined switching position. Through this can also be achieved that, even in the case of a breakdown of this class, ensure reliable operation and, in special with proper switching, reliable protection to through the drive element according to the invention.

Although, as mentioned, for the drive element according to the invention is not necessary, it may be advantageous, however, that it additionally shows a transmission unit In this case the transmission unit is attached to a central station by means of a mechanism to remote data transmission, such as a double conductor. By by means of this it becomes possible that the valuation unit can programmed from the central station through transmission to data distance In this way they can for example be deleted or centrally block access authorization codes for lost code media You can also add codes. It is also preferred in this case that the valuation unit store the times and codes of the drive processes executed, so that these can be transmitted, so advantageous, from the transmission unit to the central station. From This mode makes it possible for all opening processes and closing of the drive element are registered and can control Only one double driver is needed here for one remote feeding of this class, that is, for the power supply for the blocking process and the possibility of remote data transmission.

Description of preferred embodiments of the invention

In fig. 1 has been represented as an example of execution of the invention, a crankshaft plate 12, which combines during installation with a 10 grip shell (represented in fig. 2). In the plan view the circular line outer indicates the contour of the grip shell 10, while the crankshaft plate 12, arranged according to the representation of fig. 1 "behind" the grip shell 10, is covered in mostly by the 10 grip shell. In detail you can recognize the crankshaft plate 12, in its left region, a interlocking tab 14 and in its upper right region a drive heel 16. These elements correspond to the particularities of a standard crankshaft plate.

While using the crankshaft plate 12 shown with a separate closure system, the drive heel 16 it is used for gearing with a lever (not shown), which is applied to a separate closing system and is actuated when unraveling the lock. At this point we want to refer to the drive element according to the invention can be used in multiple forms, because of this particularity, in the form of grip shell 10 and standard crankshaft plate 12, and can used for example to replace a drive element equipped with the same connections in an existing housing, to provide this of an additional security function, as described in continuation.

In the form of execution of the element of drive according to the invention shown in fig. 1, the closing system has however been integrated into the provision composed of 10 grip shell and crankshaft plate 12. Especially It is located approximately in the center of the crankshaft plate 12 a locking system 18, for example in the form of a lock with disk guard, with a key opening 20 (represented schematically). The closure system 18 is supported on the door of the housing to be blocked and prevents, by engaging a heel 22 with a shoulder 24 on the crankshaft plate 12, the rotation of the grip shell 10 and crankshaft plate 12 applied thereto. It should be noted that in the alignment of the crankshaft plate 12 shown in fig. 1, the locking tongue 14 engages with an edge of the housing opening, such that until the crankshaft plate 12 (in the case shown clockwise) is not makes possible an opening of the door, to which it is applied the grip shell 10 rotatably with the crankshaft plate 12. As explained below more precisely, to the plate of crankshaft 12 have also been applied closing rods.

In the combination of 10 grip shell and plate of crankshaft 12 usual in the state of the art, which interlock by means of heel 32 through the closure system 18, it is with this enough the unlock of the lock 18 to make possible a rotation of the crankshaft plate 12 and an opening of the doors of Case. To increase security against unauthorized access to a housing, the crankshaft plate 12 shown in fig. 1 is also provided with a locking mechanism 26. This is applied to the crankshaft plate 12 and shows in the indicated case a bolt cylindrical 28, which meshes with the heel 22 of the closure system 18 in the locked position (shown in fig. 1). Through this engagement prevents an unlocking of the closure system 18 and the rotation, which by means of this becomes possible, of the crankshaft plate 12.

In accordance with the invention this is done with this the release of the locking mechanism 26 is necessary, in order to execute the aforementioned processes. For this it has been applied behind the grip shell 10 a reader system 30, which is configured of such that a contactless reading of a support of code, which belongs to the drive element according to the invention. According to the invention, it is assessed in a unit of titration (arranged on the rear side of the crankshaft plate 12), the information stored in the code carrier that you have read the reader system 30 and is compared with authorization codes of stored access. If the result is positive, the locking mechanism 26, such that it becomes possible, to unlock the housing doors, the corresponding movement of the closure system 18 and the rotation of the shell combination of grip 10 and crankshaft plate 12. In this way they are necessary, with independence from each other, the unlocking of the closure system 18 and the unlocking the locking mechanism 26, to authorize access to The protected housing.

In fig. 2 has been represented, in a representation in court, another form of execution of the element of drive according to the invention in the form of a shell of grab 10 with a crankshaft plate 12. In the execution example depicted in fig. 2, the reader system 30 is installed in the closure system 18 and reads the information without contacts stored in a code carrier that, in the case shown, is integrated in the key 32 of the locking system 18. Also, in the Execution example shown in fig. 2 locking mechanism 26 is applied to some extent to the rear side of the system close 18, while in the execution example according to the fig. 1 is provided on the side of the closure system 18. With the same mode of operation as in the form of execution according to fig. 1, the locking mechanism 26 acts on the system of closing 18, such that an unlocking of the closing system 18 It is only possible if the information stored in the support of code matches a stored access authorization code in the evaluation unit 34. In fig. 2 can be recognized well the application of the assessment unit 34 to the rear side of the crankshaft plate 12.

As soon as a rotational movement of the closure system 18 and a rotating movement of the shell of grip 10, together with the crankshaft plate 12, in relation to the doors 36 represented in part, can move up or down, by turning the crankshaft plate 12 (according to fig. 1 clockwise), the closing linkages 38 or 40 applied to it. In the case shown, the closing rod lower 38 is arranged, according to the representation of fig. 1, in the lower left region of the crankshaft plate 12, while the upper closing rod 40 is applied rotatably to the upper right region of the crankshaft plate 12. As a consequence of this, the rod lower closure 38, when turning the crankshaft plate 12 in direction schedule, and the upper closing rod 40 down, such so that the ends of the two closing rods 38, 40, which in locked state gear with the edges of the housing opening, they are retracted by these edges and an opening of the Case. As mentioned, according to the invention for this no only one unlocking of the closing system 18 is necessary, but a unlocking the locking mechanism 26 independent of it.
