Definitions

  • the invention relates to a security and access control system for a telecommunication cabinet. Moreover the invention relates to a telecommunication cabinet with a door comprising a security and access control system.
  • EP 0 794 306 A2 discloses a telecommunication cabinet with a door and a security and access control system.
  • the cabinet has locking means that can be moved from a first position where the door is locked into a second position where the door can be opened. It also comprises blocking means that cooperate with the locking means and help to secure the locking means in its first position.
  • In the cabinet is integrated an electronic system, displaying the status of the door, of the locking means and of the blocking means.
  • a blocking device cooperating with locking means is described in DE 195 46 035 A1 .
  • This document discloses a safe with a door.
  • the door comprises several locking bars that can be moved from a first position where the door can not be opened into a second position where the door can be opened.
  • the door also comprises a magnetic switch with a lifting magnet and a blocking pin. When the magnetic switch is activated the lifting magnet moves the blocking pin in a position where the blocking pin is blocking a movement of the locking bars when they are in its first position so that the locking bars cannot be moved into its second position and the door cannot be opened. After reactivating the magnet switch once again the blocking pin moves back into a position where it does not interact with the locking bars.
  • GB 2 204 354 A discloses a locking unit with a device for detecting the position of movably arranged peaces within a locking unit.
  • the locking unit comprises a plate that is pivotally connected to a housing of a locking unit and a sensor for detecting the angular position of the plate.
  • US 6 705 665 discloses an electromotively activated locking system for a motor vehicle door which includes an outer door opener, at least one inner door opener, a lock mechanism that can be regulated by a motor drive and an element separating the wet and dry areas.
  • the lock parts of the primary lock mechanism are located in the damp area.
  • An electrical device for determining the locking state of the primary and secondary lock mechanisms and the motor drive are located in the dry area.
  • a logic alignment is carried out between the locking states of the primary locking mechanism and the locking states of the secondary locking mechanism and certain lock functions are then released or blocked for control in dependence on this logic alignment.
  • DE 43 02 835 C1 discloses a security and access control system for a telecommunication cabinet according to the preamble of claim 1.
  • the system comprises a door closure having a bolt holding the door in its closed position and an associated operating device.
  • a locking device allows 2-stage operation of the bolt, with a remote unlocking of the second operating stage activated upon the first operating stage being switched in.
  • the present invention provides a security and access control system for a telecommunication cabinet with a door, comprising
  • the invention provides a system for a telecommunication cabinet with a door that helps to secure the cabinet and with which the cabinet can be controlled. For example it can be controlled when the locking means is activated and the door can be opened as well as the other way around when the locking means are activated to lock the door. Furthermore the invention provides the possibility of controlling access to a telecommunication cabinet from a distance. This may be achieved by connecting the controlling means to a communication line or other communication device.
  • the system according to the invention comprises locking means that is movably arranged in the cabinet and locks the door in one position and unlocks the door in another position.
  • the mechanical module comprises blocking means that is also movably arranged within the cabinet and works together with the locking means. In a first position of the blocking means it prevents a movement of the locking means and in a second position it allows a movement of the locking means.
  • the system according to the invention also comprises transmitting means that is designed to transmit a movement of the locking means to a movement of the blocking means so that the movement of the locking means for example from its first position into its second position causes a movement of the blocking means from one position to another position.
  • the system typically comprises control means such as sensors, reed contacts, switches or the like to detect and display the position of the blocking means as described below.
  • the system may also comprise means for activating parts of the mechanical module such as for example a motor.
  • the electronic module generally further comprises a communication device to transfer information from the cabinet to a remote place and vice versa.
  • the system according to the invention typically provides the possibility of controlling access to the cabinet and of monitoring the status of the cabinet especially the status of the components of the mechanical module and the door of the cabinet.
  • the control means may detect that the blocking means is in its first position. Whereby the locking means is secured in its first position and cannot be moved and thus the door is closed and locked. If for example the control means detects that the blocking means is in its second position then the locking means could be moved for example in its second position and the door could be opened since it is no longer locked. If the door needs to be opened the locking means needs to be moved from its first position in its second position (otherwise the door would still be locked).
  • the controlling means detecting a movement of the blocking means is thereby also able to detect a movement of the locking means and thus the status of the cabinet.
  • the system is able to detect the following different conditions:
  • the possibility to detect every single status of parts or components of the mechanical module of the security and access control system according to the invention helps to control the cabinet. This control possibility improves the security standard of the cabinet. Further the electronic module helps granting access to the cabinet.
  • the information provided by the access control and security system according to the invention could be useful for example for a telecommunication company to control the time between opening and closing the door and thus how long someone is working at the telecommunication cabinet.
  • the system according to the invention can also be used in connection with an alarm system if the cabinet stays open for too long or past a certain time.
  • the locking means comprises at least one bar.
  • a bar is a common component used in telecommunication cabinets for locking means.
  • a bar is easy to manufacture and therefore cost effective. It is possible to use one bar for a one-point locking mechanism. To improve the security of the cabinet it is also possible to use more than one bar for example two bars (two-point locking mechanism). It is also possible to use at least one bar and at least one other locking means to get for example a three-point locking mechanism.
  • the invention is independent from the number of bars / locking means that are used.
  • the bar can be slidably arranged in the cabinet. It is also possible to arrange the bar in another way e.g. pivotally.
  • the way the bar is arranged inside of the cabinet typically depends on the geometry of the cabinet as well as on the kind of locking mechanism that is being used.
  • the bar For moving or activating the bar to open the door, the bar may be connected to a handle that can be accessed from outside the cabinet.
  • a handle that can be accessed from outside the cabinet.
  • Any kind of handles can be used such as for example a turning handle or a swinging lever handle.
  • Any kind of locking unit can be integrated in the handle or cooperate with the handle such as for example a single locking unit or a multi locking unit.
  • the blocking means comprises at least one bar.
  • a bar may be conveniently used as a component for transmitting movements and forces.
  • a bar can be easily manufactured and is thus a cost effective solution.
  • the bar can be pivotally and/or slidably arranged within the cabinet. Both kinds of arrangements are kinematically equivalent possibilities to movable arrange a bar in a system.
  • the kind of bar that is used typically depends on the geometry of the cabinet and the kind of locking mechanism that is used.
  • the present invention provides blocking means comprising at least one Bowden cable.
  • a Bowden cable is a flexible device for transmitting movements and forces.
  • the use of a Bowden cable may have the advantage that it is possible to flexibly arrange the components or modules of the access control and security system around each other and in the cabinet.
  • the Bowden cable can transmit forces and movements over all different kind of geometric arrangements and between modules being arranged in very different ways. Especially when retrofitting the access control and security system according to the invention this is generally an advantage because the system can be integrated in all different kind of cabinets and geometric arrangements and it can be mounted in different ways.
  • the blocking means may be moved by a motor.
  • a motor is conveniently used means for an actuator. It is also possible to use any other actuation element to move or to activate the blocking means such as a piezoelectric element, lifting solenoid etc.
  • the transmitting means is fixed at the locking bar.
  • the way to transmit a movement of the locking means to the blocking means is achieved by mounting the transmitting means on the locking bar. Accordingly, movement of locking means will cause movement of the transmitting means mounted on the locking bar.
  • the transmitting means comprises a receiving portion for receiving the blocking means in its first position to prevent a movement of the locking means.
  • a very simple solution to solve this is to arrange locking means, blocking means and transmitting means so that the transmitting means are mounted at the locking bar and that the blocking means in its first position abuts the transmitting means.
  • the transmitting means may comprise a recess that prevents the movement of the locking means from its first position into its second position when the blocking means is in its first position.
  • the transmitting means can have a transmitting portion for converting a movement of the locking means into a movement of the blocking means.
  • One possibility to shape the transmitting portion can be a gliding surface, on which the movement of the locking means can easily be transmitted to a movement of the blocking means since the blocking means can easily glide along the surface of the transmitting means. Any other solutions for mechanical transmitting a movement can be used as well.
  • the system can comprise at least one sensor to detect the position of the blocking means. Sensors typically are cost effective solutions to detect and send different kind of information.
  • the information can be sent electronically and can be analysed in the control means of the access control and security system of the invention.
  • the system according to the invention can also comprise at least one sensor that detects the position of the motor.
  • the information collected by the sensors can be stored in the electronic module of the invention, it can be processed and/or sent over a telecommunication line to a remote place such as for example other facilities of a telecommunication company or a control centre.
  • the blocking means may comprise at least one breaking piece.
  • a breaking piece allows for emergency opening the door when no electricity is supplied to the telecommunication cabinet and therefore the motor cannot be activated and cannot move the blocking means.
  • the breaking piece of the blocking means By removing the breaking piece of the blocking means the mechanical contact between the blocking means and the transmitting means respectively the locking means is abolished and thus moving the locking means and opening the door of the cabinet is unabled, respectively.
  • the present invention also provides a telecommunication cabinet with a door and a security and access control system comprising
  • Fig. 1 the inside of a door 1 of a telecommunication cabinet is shown.
  • the door 1 comprises a three-point locking mechanism with two slidably arranged bars 2 and 3 and with one pivotally arranged bar 4.
  • the pivotally arranged bar 4 is fixed at the rear side of a turning handle 5.
  • the handle 5 When the handle 5 is rotated - as would be the case when someone opens the door 1 - the bar 4 rotates together with the handle 5.
  • the slidably arranged bars 2 and 3 are also connected with the rear side of the handle 5.
  • the mechanical connection between the handle 5 and the bars 2 and 3 transfers a rotation of the handle 5 into a translational movement of the bars 2 and 3.
  • the bars 2 to 4 can be moved from a first position where they lock the door 1 into a second position where the door 1 is not locked and can be opened.
  • the cabinet could comprise receiving means for receiving the bars 2 to 4 for locking the door 1 when the locking bars 2 to 4 are moved into their first position.
  • the receiving means could comprise a recess in the frame of the door 1 or any other mechanical means that prevents a movement of the bars 2 to 4 into the opening direction of the door 1 when the bars 2 to 4 are in their first position and thus lock the door 1.
  • the handle 5 also interacts with a commonly known locking unit 6 with a key (not shown).
  • the handle 5 and the locking unit 6 can also be designed as one part, e.g. the locking unit 6 is integrated in the handle 5.
  • the locking unit 6 can be a single locking unit or a multiple locking unit.

They are connected via a Bowden cable 9 and will be described in detail with reference to Fig. 2 . It is also possible to integrate all components of the invention in one module.
  • the use of two or more modules has the advantage that the system can be flexibly arranged within a cabinet. Therefore the system according to the invention can be used for retrofitting a cabinet.

  • the receptacle of the adapter 16 for the bar 2 is designed to fit to all different kinds of shapes of bars, for example to bars with a round, a rectangular or a square profile. That is achieved by shaping the receptacle so it can be fixed around all kinds of common bar shapes, e.g. by integrating a triangular shaped groove into the receptacle that extends in the same direction as the axis of the bar 2.

  • the motor 17 can be switched between two different stages. In a first stage of the motor 17 the motor 17 is in an open stage and spring elements 25 forces the Bowden cable 9 into its first position - as shown in Fig. 2 . In that stage the Bowden cable 9 prevents the bar 2 from moving and thus blocks the bar 2. From Fig. 2 can be seen that the Bowden cable 9 in this position abuts the adapter 16.

  • the blocking means 12 When the blocking means 12 is in its first position - as shown in Fig. 3 a) - the right end side of the blocking means 12 abuts the abutment area 23 of the adapter 16. In this situation the motor 17 is in its open stage and the spring elements 25 push the blocking means 12 against the adapter 16. With one side the blocking means 12 contacts the nose 24. The nose 24 prevents that the bar 2 can be moved downward into its second position while the Bowden cable 9 abuts the abutment area 23 of the adapter 16. Therefore the nose 24 is arranged at the gliding surface to seat the blocking means 12 in its first position at a lower end of the adapter 16 (see arrow A in Fig. 3 c) ).
  • Fig. 3 d the situation is shown when the bar 2 has reached its third position.
  • the blocking means 12 abuts the adapter 16 at a second abutment area 26. Going back to Fig. 2 : when the door 1 is opened, the bar 2 is moved into the direction of the arrow A, the Bowden cable 9 or blocking means 12 is pushed back by the adapter 16, the Bowden cable 9 or the blocking means 12 gets next to the sensor S3 and the sensor S3 detects this status.
  • the motor 17 always moves back into its first closed stage. That can happen after a certain amount of time has passed by. In this position the motor can be used again as an actuator to move the blocking means from its first position into its second position. For closing the door the bar 2 has to be moved back from its second position into its first position thereby moving the adapter 16 as well. Since the motor 17 is in its closed stage again and the spring elements 25 are working into the direction of the adapter 16 the blocking means 12 will also move back into its first position abutting the adapter 16 at the abutment area (see Fig. 3 d) to a)).

The nose 24 prevents that the bar 2 can be moved into its second position in the direction of the arrow A in Fig. 6 while the blocking bar 37 abuts the abutment area 23 of the adapter 16.
  • the leg spring 32 is pushing the blocking bar 37 against the adapter 16 so the blocking bar 37 always contacts the adapter 16 as can be seen in Fig. 4 .
  • a movement of the bar 2 from its first position into its second position (arrow A) results in a rotation of the blocking bar 37 around the bolt 36 against the force of the leg spring 32 (arrow B) into its third position.
  • Fig. 6 c the situation is shown when the bar 2 has reached its third position. In this situation the blocking bar 37 abuts the adapter 16 at a second abutment area 26. In the situation shown in Fig. 6 c) the motor 17 is still open. Compared with Fig. 6 a) where the lever 31 points with its outer edge, which is opposite of the bolt 36, to the left the lever 31 is pushed into a position where it points to the right in Fig. 6 c) . In Fig. 6 d) the motor 17 is closed, the lever 31 is rotated back into the position of Fig. 6 a) (arrow C).
  • the control unit of the system according to the invention can be programmed in the way that the motor 17 always will move back into its closed stage after a certain amount of time has passed by. In that position the motor can be used again as an actuator to move the blocking means form its first position into its second position.
  • Sensor S4 detects when the bar 37 is in its first position ( Fig. 6 a) ).
  • Sensor S4' detects the same situation as sensor S4 at another point in the system. It detects when the bar 2 is in its first position by contacting the fixing arrangement 28 of the adapter 16.
  • the sensor S3 detects when the bar 37 was moved by the adapter 16 into its third position ( Fig. 6 c) ).
  • the function of the sensor S5 will be described in connection with Fig. 7 .
  • Fig. 7 the situation is shown when the security and access control system is prepared for an exit in the case of an emergency, for example when the electricity is out.
  • the pivotally arranged bar 37 is destroyed.
  • the outer edge of the bar 37 (breaking piece) is eliminated. That can for example be achieved by drilling through the door 1 and the mounting plate 33 at a defined spot. Because of the leg spring 32 the destroyed bar 37 is pushed into the direction of the arrow D. Hence the bar 37 does not contact the adapter 16 any more and the bar 2 can be moved into the direction of the arrow A giving the door free.
