Abstract
Description
[0001] The invention relates to a safety system for securing escape routes and a door with the safety system.
[0002] Safety systems with an emergency button for securing escape routes are known. When the emergency button is pressed, a door lock is unlocked, allowing a user to escape in case of danger. EP 2 725 172 A2 discloses the ability to connect an emergency button and a door lock via a bus system.
[0003] The object of the present invention is to provide a safety system that, with a simple design, enables safe escape route protection at a door.
[0004] This problem is solved by a safety system according to independent claim 1. Advantageous embodiments of the safety system are specified in the dependent claims, the description, and the figures.
[0005] The task is thus solved by a safety system for securing the escape route. This safety system includes a door operator. The door operator is designed, for example, as a door handle or door knob and serves for the manual, mechanical opening of a hinged or sliding door. Furthermore, the safety system includes an electric door lock for locking the door. This door lock will be explained in more detail below. In addition, the safety system includes a release element. This release element can be activated by a user, thereby unlocking the door lock and thus clearing the escape route. This release element is integrated into the door operator. Therefore, the release element is not located on the door frame or on the wall next to the door frame, but rather within the door operator itself – the element that the user would normally grasp to open the door.This makes it possible, in particular, for the user to manually open the door and simultaneously activate the release mechanism with just one hand and essentially a single movement. This results in a very intuitive use of the escape route.
[0006] The release element preferably comprises an actuating element. Actuation of the actuating element triggers the door lock to unlock the door. The release element is preferably designed as an emergency stop button. In this case, one actuating element of the release element corresponds to the actuating element of the emergency stop button.
[0007] Locking refers to the process of moving the door lock into a locked position. Unlocking refers to the process of moving the door lock into an unlocked position.
[0008] The door lock can be, for example, electromechanical or purely electromagnetic. The door lock includes, for example, at least one coil. Controlling the door lock for locking or unlocking can be achieved, in particular, by switching an electrical power supply on or off. The electrical power supply can be used to provide the coil with electrical current.
[0009] One possible door locking mechanism is described by way of example in DE 10 050 111 C1. In the unlocked state, for example, no magnetic forces act on the door. In the locked state, for example, magnetic forces act on a door.
[0010] An electromechanical door lock has a mechanical connection to the door when locked. When unlocked, this mechanical connection can be disengaged or removed.
[0011] For example, an electromechanical door lock can have a locking element, i.e., a bolt or door latch, which is in a retracted position when the door lock is unlocked. In the retracted position, the locking element is not engaged with the door. In the locked position, the locking element is engaged with the door.
[0012] In another alternative electromechanical door lock, the door lock is constructed like a door opener. That is, the locking mechanism includes a latch element. When the door lock is engaged, the door latch engages with the lock. When unlocked, the latch element releases the door latch so that it can disengage from the lock, particularly by applying pressure to the door.
[0013] Preferably, switching off the electrical power supply results in the door lock being unlocked. Thus, the door lock is controlled to unlock by switching off the electrical power supply.
[0014] Preferably, switching on the electrical power supply results in the door lock being locked. Thus, the door lock is controlled by switching on the electrical power supply.
[0015] The "user" can be any person who uses the security system. For example, a user could be a guest who wants to escape through the door secured by the security system.
[0016] The safety system serves primarily to secure escape routes. It therefore serves to release the escape route. This means that actuating the release element leads to unlocking without user authentication. Unlocking can occur immediately or after a time delay.
[0017] The release element can trigger the door lock to unlock. Initiating an action refers specifically to sending a message via a bus system containing information and / or a command that prompts the direct or indirect recipient of the message to perform the action. The sender of the message initiates the action. Thus, initiating an action is understood as indirect control. For example, the release element can send a message via a bus system to a door lock controller, whereupon the door lock controller activates the door lock to unlock. The release element can, in particular, trigger the unlocking of the door lock with a time delay.
[0018] Preferably, the door operator is designed exclusively for one-handed operation.
[0019] Such a door operator for exclusively one-handed operation is in particular a door handle or door knob, but not a panic bar.
[0020] When designing a door handle (also called a door lever), it is preferably provided that the handle includes a gripping area. This gripping area is accessible to the user's hand. The release element is positioned so that it can be pressed by the thumb of the gripping hand. Particularly preferably, the handle also includes a connecting area that links the gripping area to the door leaf or the lock.
[0021] Furthermore, it is preferably provided that the handle area is a maximum of 20 cm, in particular a maximum of 15 cm, and can therefore be operated with only one hand.
[0022] As an alternative to a door handle, the door operator can, for example, be designed as a door knob. The door knob can be rotatable, with the latch being retracted by turning it. Alternatively, the door knob can also be fixed and simply used by the user to push the door open.
[0023] Furthermore, the door operator can be designed not only for one-handed operation and may, for example, be designed as a panic bar.
[0024] The door actuator preferably includes an integrated light source, for example, one or more LEDs. The light source indicates the door locking status. It can be fully or partially integrated into the release element. However, it is also possible to integrate the light source into the door actuator independently of the release element.
[0025] In a design of the door operator as a door handle, it is particularly provided that the light source is arranged along the handle area, preferably on an upper edge and / or lower edge of the handle area.
[0026] Furthermore, it is preferably provided that a message legible by touch for blind persons is arranged in the door operator. This message is written in Braille. The message provides information on the arrangement of the release element in the door operator.
[0027] According to the invention, the security system comprises a lock with a lock case. The lock is, in particular, integrated into the door leaf. The door operator described above preferably serves to actuate a latch of the lock.
[0028] The lock is preferably designed as a self-locking panic lock.
[0029] The lock may include a bolt and / or a latch.
[0030] The door locking mechanism is arranged as a separate assembly, independent of the lock.
[0031] According to the invention, it is provided that a power and / or data-carrying connection of the release element is made via the lock, in particular via the lock case.
[0032] The lock preferably includes lock electronics within the lock case. The lock electronics may include a processor / controller. In particular, the lock electronics may correspond to a lock electronics system.
[0033] The lock's electrical system can include at least one sensor. The sensor can be designed, in particular, as a switching or reed contact. The sensor can serve to detect at least one position of a mechanical element of the lock. The mechanical element can be the bolt, the latch, a control latch, and / or a slide.
[0034] The lock's electrical system may additionally or alternatively include an electromechanical actuator. This electrical system is controllable, in particular allowing the bolt and / or latch of the lock to be actuated by the controllable electrical system. The electromechanical actuator is, in particular, an electric motor or electromagnet. The sensor may be configured to detect the position of a lock mechanism connected to the actuator.
[0035] Preferably, a common connector is provided on the lock case. A cable harness can be connected to this connector. The lock electronics and the release element are thus connected simultaneously via this connector.
[0036] Specifically, it is planned that a common cable harness with several cables will be routed through the door. This cable harness will be routed primarily inside the door leaf. The lock electronics and the release element will be connected to cables within this common cable harness, specifically via the common connector described above.
[0037] The cable harness preferably runs from the door leaf, over the frame, to the outside, for example to a control unit and / or a monitoring device, from which the lock, door locking mechanism, and / or release element can be monitored remotely. The monitoring device can be part of the security system.
[0038] If the connector described above is omitted on the lock case, the cable harness preferably leads into the interior of the lock case and is connected directly to the lock electrical system and the release element lines inside the lock case.
[0039] Furthermore, it is preferably provided that the lock electronics and the release element for data transmission are connected to different cables of the common cable harness. This allows for independent analog or digital control of the lock electronics and the release element.
[0040] Alternatively, the lock electronics and the release element can be connected to the same bus and therefore, in particular, to the same cables for data transmission. This allows for individual digital control of the lock electronics and the release element.
[0041] Furthermore, it is preferably provided that at least one release element cable is routed through the lock case. The release element cable serves for data and / or power transmission to the release element. The release element cable is, in particular, connected to or attached to the described connector. In particular, several release element cables are provided that are routed through the lock case.
[0042] The respective release element cable runs in particular from the release element to the lock case.
[0043] The invention further comprises a door with the described security system.
[0044] The invention is explained in more detail below using an exemplary embodiment. Technical features with the same function are indicated in the figures with identical reference numerals. The figures show: Figs. 1 and 2 are two schematic views of the security system according to the embodiment according to the invention, Fig. 3 is a lock of the security system according to the embodiment according to the invention with a first connection variant, Fig. 4 is a lock of the security system according to the embodiment according to the invention with a second connection variant, Fig. 5 is a door actuator of the security system according to the embodiment according to the invention, designed as a door handle, and Fig. 6 is a door actuator of the security system according to the embodiment according to the invention, designed as a door knob.
[0045] Fig. 1 and 2 Figure 1 shows an overview of security system 1. Security system 1 is used on a door 2. The door 2 is rotatably mounted in a frame 3.
[0046] As the schematic representation in Fig. 2As shown, inside door 2 is a lock 8 of the security system 1. A door operator 7 is connected to a spindle 10 of the lock 8. This door operator 7 is shown in the Figure 1 .
[0047] Furthermore, the security system 1 includes a door lock 5, which connects the door 2 to the frame 3 electromechanically or electromagnetically in the locked state.
[0048] In the illustrated embodiment, the lock 8 is connected to a control unit 4 via a cable harness 17. The door lock 5 is also connected to the control unit 4. A release element 6 is located in the door actuator 7. This release element 6 is connected to the control unit 4 via the lock 8 and the cable harness 17, transmitting data. This makes it possible to actuate the door lock 5, in particular to unlock it, by actuating the release element 6.
[0049] Fig. 3Figure 8 shows the lock. The lock 8 comprises a lock case 9. Latches 11 and a bolt 12 protrude from this lock case 9. The latches 11 and / or the bolt 12 can be operated by a lock motor 13. Thus, the latches 11, the bolt 12, and the lock motor 13 together form the lock's electrical components.
[0050] A connector 14 is located on the lock case 9. The cable harness 17 can be connected to this connector 14. In the example shown, the cable harness 17 includes two cables 18 for data transmission. The cable harness 17 can also include additional cables for data transmission and / or power cables.
[0051] The diagram with the two cables 18 for data transmission is intended to illustrate the connection of the lock electronics 11, 12, 13 and the release element 6 to one and the same bus. As shown in the schematic diagram in Fig. 3As shown, the two cables 18 inside the lock case 9 lead to a bus interface 19. The lock electronics 11, 12, 13 are connected to this bus interface 19 via lock wires 16. Furthermore, release element wires 15 lead to the bus interface 19.
[0052] These release element lines 15 serve to provide power and / or data to the release element 6 in the door operator 7. In the example shown, the release element lines 15 are routed from the lock case 9 through the handle spindle 10 to the outside. However, other cable routing is also conceivable.
[0053] Fig. 4 It also shows castle 8 in a schematic representation.
