Description

The present invention relates to a closure device for a closing element which can be displaced back and forth between an open position and a closed position, in particular a sliding door, with an actuating element which can be rotated or pivoted about an actuating rotational axis and a closure element which can be actuated via the actuating element.

Such closure devices are used in very different areas and can be used for all possible sliding closure elements, such as for sliding doors, sliding windows or sliding hatches.

Corresponding closing elements can be used, for example, to seal off certain areas such as offices, bank rooms, walk-in closets, safes, or server rooms and thus protect against unauthorized access. For this purpose, the closing elements are movable back and forth between a closed position and an open position, wherein access to the corresponding areas is made possible in the open position and prevented in the closed position.

In order to lock the closure elements in the closed position, so that they can not be opened, the closure devices usually have one or more closure elements which can be actuated via an actuating element. About the actuating element, the closure devices can be transferred from a locking position, in which the closing element is not movable, in an unlocked position, in which the closing element can then be moved and opened.

In general, the closure elements engage in the locking position in the manner of a hook in a corresponding contour, which is arranged for example on the frame of the closing element, so that the closing element can then no longer be moved.

The actuators are usually rotatably or pivotally mounted about an actuating axis of rotation and can be moved manually, for example manually by hand between an unlocked position and a locking position. This movement is then transmitted to the closure element, so that this can either prevent a movement of the door in the locking position or allow in the unlocked position.

The design of the actuators can be quite different. For example, simple tabs, latches, handles or knobs can be used. In high-quality and possibly additionally secured locking elements but also more complex actuators can be used, such as so-called pivot lever, which must first be expanded from a arranged on or in the closing element recording and only then in the next step to unlock the closure element can be twisted or swiveled. Such a fold-out actuator is for example in the EP 1 900 891 A2 described.

Although in the past closure devices of the type mentioned have proven to be quite useful, however, they always require for unlocking the closure elements that the closure element is actuated via the actuating element. This can lead to problems when people enter an otherwise closed room, such as a server room, and the closing element behind them is inadvertently closed. Since the actuating element has to be actuated in order to unlock the closure elements and to open the closing elements, but as a rule this can not be achieved from inside the room, trapped persons in such a situation are dependent on outside help. Sometimes it can even lead to a danger to life and limb, if the people receive no outside help.

On this basis, the invention has the object to provide a closure device with which such a risk is reduced.

This object is achieved by a closure device of the aforementioned type characterized in that the closure element and the actuating element are coupled to one another via a Notentkopplungsvorrichtung. Advantageous developments are part of the dependent subclaims.

The emergency decoupling device enables a decoupling of the closure element and the actuating element. Due to this decoupling, the closure element can also be actuated directly and without actuation of the actuating element itself. In particular, in an emergency situation, therefore, the closure element can be transferred independently of the actuating element of a locking position in a Notentriegelungsstellung and the closing element can then be opened. Unintentionally trapped persons are no longer dependent on assistance to open the closing element, but they can emergency unlock the closure element without tools and then open the closing element independently.

With regard to the emergency decoupling device, it has proved to be advantageous if it is configured such that the closure element for emergency release is movable relative to the actuating element. By this relative movement is made possible that the closure element can be transferred from the locking position into the Notentriegelungsstellung even if the actuator is not movable. This is particularly advantageous if the actuators are designed to be self-locking and this, when the closing element is closed, are in a locked or fixed position, as is the case with the above-mentioned fold-out pivot lever actuation. A direct actuation of the closure element is then possible only due to a relative movement of the closure element relative to the actuating element. The emergency operation of the shutter device is therefore independent of whether the actuator is movable or not.

With regard to the arrangement of the closure element and the actuating element, it has proven to be advantageous if the actuating element can be actuated by a first side of the closing element and the closure element for emergency unlocking of a second side of the closing element is notbetätigbar. For example, the first side may be the outside of the closure member and the second side may be the inside of the closure member. The actuating element can be actuated exclusively by the first side of the closing element and can not be reached from the second side. The arrangement of the closure element on the second side of this can be emergency operated from the space to be closed with the closing element.

Constructively, the actuating element may have a portion which is passed through the closing element. The actuating element may comprise a handle or a handle for actuation, which may be arranged on the first side of the closing element. The handle and the closure member may be disposed on opposite sides of the closure member. The closure element can be arranged on the side of the closing element on which the emergency decoupling device is also arranged.

Furthermore, it has proven to be advantageous if the closure element is rotatable about a relative axis of rotation. The closure element can be pivoted or rotated by a rotational movement about the axis of relative rotation of the locking position in the Notentriegelungsstellung. It is particularly advantageous if the closure element has to be turned or pivoted downwards into the emergency unlocking position. In this way, a simple emergency release is possible, since the emergency release a force acting in the direction of gravity force must be applied. It is also possible that the closure element has an emergency handle, an emergency contact or an emergency operating area, via which an emergency unlocking force can be exerted on the closure element. The closure element can be manually transferred into the emergency unlocking position. Furthermore, it is also possible that the closure element arranged emergency operation areas are illuminated and / or provided with a warning color and / or with an instruction, so that it is immediately apparent to trapped persons that an emergency release of the closure element is possible.

It has also proven to be advantageous if the relative movement of the closure element relative to the actuating element is limited. By such a limitation of the relative movement, the closure element can only be moved so far that this occupies a Notentriegelungsstellung and the closure element can be opened. The closure element, for example, in a range of motion, in particular an empty angle range, relative to the actuating element moves, in particular rotated or pivoted, be. When the movement range is exceeded, the closure element can no longer be moved relative or independently relative to the actuation element. If the actuating element is blocked or inhibited, for example, the movement of the closure element outside the movement range is thus blocked or inhibited.

Furthermore, it has proven to be advantageous if the actuating rotational axis and the relative axis of rotation are arranged parallel to each other. Such an arrangement of the two axes allows a compact design. The closure element can be rotated about the actuating element about the actuating axis of rotation and at an emergency decoupling about the relative axis of rotation.

A preferred embodiment provides that the emergency decoupling device is arranged on the front side on the actuating element. The emergency decoupling device can be arranged on a region of the actuating element projecting through the closing element. This region of the actuating element can be designed in the manner of a shaft. The actuator can be releasably connected to the emergency decoupling device, which allows easy installation of the closure device.

With regard to the design of the emergency decoupling device, it has proved to be advantageous if it has a first region which is coupled in a motion-coupled manner to the actuating element and has a second region which is coupled in a motion-coupled manner to the closure element. Due to the possible relative movement of the closure element relative to the actuating element, the two regions of the emergency decoupling device can also be movable relative to one another, in particular pivotable or rotatable. It is possible that the first area is pivotally connected to the second area. The second region may be detachably connected to the first region via a screw connection, in particular, the second region may be pivotably mounted on the first region. It is also possible that the first area is coupled to the shaft of the actuating element. The second region can be integrally connected to the closure element, which can lead to increased stability. The two areas can be designed like a disk.

Furthermore, it has proven to be advantageous if the first region has a coupling element and the second region for limiting the movement of the closure element has at least one stop. Preferably, the second region has two stops, wherein in an emergency unlocking position, the first stop rests against the coupling element and, in the locking position, the second stop bears against the coupling element. By or the attacks limiting the movement of the closure element relative to the actuating element is achieved. The closure element can only be moved so far for emergency release until the coupling element strikes against a stop. The coupling element can be designed as a screw, bolt or projection and integrally or detachably with be connected to the first area of the emergency decoupling device. The stops can be the end regions of a slot. The coupling element can be guided in the slot and move in a movement in the slot. Furthermore, it is also possible that the second area has only one stop for limiting the movement in one direction. If the actuator is locked, for example, this lock can prevent movement of the connecting element. In an alternative embodiment, the first area of the emergency decoupling device can also have one or two stops and the second area can have a coupling element. Nothing changes in the described functionality due to the arrangement of the coupling element and of the stop or stops.

In a further development of the invention, the coupling element and the relative axis of rotation with respect to the rotational axis of movement opposite each other. Such an arrangement leads to a compact design and an associated space-saving design of Notentkopplungsvorrichtung. The first region of the emergency decoupling device can, for example, be pivotably connected to the second region on one side and have the coupling element on the side opposite the actuation rotational axis.

Furthermore, it has been found to be advantageous if the closure element for emergency release relative to the actuating element against the force of a spring element is movable. The spring element can be designed as a compression spring and bias the closure element in the locking position. The spring element can be designed as a helical spring, torsion spring, spiral spring, bar spring or plate spring. It is also possible that the spring element is designed as a tension spring. For emergency unlocking the closure element can be moved against the force of the spring. The spring preferably engages spaced from the relative axis of rotation on the closure element, so that they exert a large moment of force can. The spring stiffness can be set such that the actuator can only be intentionally transferred in an emergency situation from the locked position to the emergency unlocking position and accidental contact or actuation of the closure element does not lead to an emergency release.

With regard to the arrangement of the spring element, it has been found to be advantageous if the first region of the emergency decoupling device is connected via the spring element to the second region of the emergency decoupling device. As a result of this structural design, the second area can be moved counter to the force of the spring relative to the first area. The spring can be supported on a projection. The projection may be arranged on the first region of the emergency decoupling device. The second region can have a spring receptacle, for example in the form of one or more indentations, via which the spring element can bias the second region. The spring element can be guided in the notch, which leads to a good stability of the spring element.

In terms of design, it has proven to be advantageous if the closure element is designed to cooperate with a locking element as a hook tongue. The locking element can be designed as a projection and protrude. Furthermore, it is also conceivable that the locking element is designed as a bolt or as a screw. The closure element can engage in a frame or an opposing closing element, in particular an opposing sliding door, for locking the closing element. The locking element may be arranged in or on the frame. An arrangement in or on an opposing closing element is possible. To lock the closing element, the closure element may be coupled to the locking element in the manner of a positive connection. In an alternative embodiment it is also possible that the locking element is arranged on the closing element and the closure device and the closure element are arranged on the frame side. In a locking position, the locking element can cooperate with the closure element such that the closure element is not movable.

With regard to the closure element, it has proven to be advantageous if this has a closing gate, which cooperates with the locking element in a closing movement of the closing element, so that the closure element is automatically transferred into the locking position. Such a configuration of the closure element allows easy locking. The closing element can be moved into the closed position and the closure element goes over automatically in the locking position. The actuating element does not have to be moved to lock the closing element. The closure device therefore has a surcharge function. When the closure member is moved from the open position to the closed position and the closure member is in the locked position, contact between the closure member and the locking member may occur. Due to the closing gate, however, this contact leads to the closure element evading and thus no large forces acting on the closure device. The closing gate can be configured as a run-on slope. In a further embodiment, instead of or in addition, it is also possible that the locking element has a closing gate. A closing gate arranged on the locking element can likewise lead to an independent locking when closing the closing element.

Further details and advantages of the present invention will be explained in more detail below with the aid of an embodiment shown in the figures. Show:

In Fig. 1 is designed as a sliding door designed closing element 2 from the inside of a closed space with the sliding door. This space can be, for example, a server room that can be accessed via the sliding door 2.

The sliding door 2 is located as shown in FIG Fig. 1 in a closed position, so that the room can not be entered or left in this position. Furthermore, on the sliding door 2 a according to Fig. 1 arranged in a locking position closure device 1, which locks the sliding door 2, so that it can not be moved. To leave the room, therefore, the closure device 1 must first in the in Fig. 2 shown unlocked position transferred and the sliding door 2 are then opened.

To unlock the closure device 1, this has an actuating element 3, which in the illustration of Fig. 3 easy to recognize. The actuating element 3 has on the outside 2.1 of the sliding door 2 a Pivot lever 3.2, which for actuating the in Fig. 2 shown folded position must first be swung out of the receiving contour 12 and then can be rotated to unlock the operating axis of rotation B. The rotational movement of the pivot lever 3.2 is transmitted via the extending through the sliding door 2 through shaft 3.1 to the closure element 4, so that this from the in the Fig. 1 shown locked position in a clockwise direction about the actuating axis of rotation B in the unlocked position according to Fig. 2 is pivoted. The pivot lever 3.2 is biased in the direction of the unfolded position, so that it automatically pivots out of the receiving contour 12 before actuation. In the presentation of the Fig. 2 the pivot lever 3.2 is shown in a swung-out position.

From the interior, so from the perspective of the Fig. 1 , can not operate the pivot lever 3.2 and unlock the closure device 1 therefore not in the way described above. If the pivot lever 3.2 accidentally or intentionally, for example, by a second person, pivoted back into the receiving contour 12, it is secured against rotation about the operating axis of rotation B.

Now, if a person is in the closed space of the sliding door 2 and the sliding door 2, for example, was accidentally closed or has fallen, this person has no way to reach the arranged on the other side 2.1 of the sliding door 2 pivot lever 3.2 and the door 2 so open. In order nevertheless to allow this person to unlock the closure device 1 and to leave the room on his own, the closure device 1 has an emergency decoupling device 5.

This emergency decoupling device 5 allows the closure element 4, which as shown in FIG Fig. 1 behind a on the frame 11 of the door 2 arranged locking element 10 engages and thus prevents movement of the sliding door 2, regardless of a movement of the actuating element 3 to move. In this way, the sliding door 2 can also be opened from the inside 2.2 forth and a caged person is not dependent on help from the outside 2.1 ago.

Subsequently, the structural design of the emergency decoupling device 5 will now be explained in more detail, before then the following will be dealt with in the subsequent operations during emergency unlocking.

The emergency decoupling device 5 consists essentially of two disk-like regions 5.1, 5.2, which can be rotated relative to one another. The area 5.1 is arranged between the area 5.2 and the sliding door 2 and is coupled to the shaft 3.1 of the actuating element 3, as well as in the sectional view of Fig. 2 can be seen. During a rotational movement of the actuating element 3 about the axis of rotation B, the first area 5.1 of the emergency decoupling device 5 also rotates about the actuating rotational axis B accordingly.

The second region 5.2 is integrally connected to the closure element 4, so that a rotational movement of the actuating element 3 is transmitted to the closure element 4 and this is also movable between a locked position and an unlocked position back and forth.

Since the closure element 4 is rotatable relative to the actuating element 3, accordingly, the two regions 5.1 and 5.2 must be rotatable relative to each other. In terms of design, this is achieved in that the second region 5.2 is rotatably mounted on the first region 5.1 of the emergency decoupling device 5.

Like this from the representation of the Fig. 1 shows, the relative movement of the two areas 5.1, 5.2 limited by two stops 7.1, 7.2. In order to limit the movement, the first region 5.1 has a coupling element 6 designed as a screw, which is guided in a slot of the second region 5.2. The stop 7.2 is in the Fig. 1 not to be seen, since this is hidden by the screw head of the coupling element 6. The coupling element 6 can move between the two stops 7.1, 7.2, which are formed by the respective end portions of the slot. Accordingly, the second region 5.2 from that in the Fig. 1 shown position as far as against the first area 5.1 are rotated until the coupling element 6 abuts the stop 7.1. A further rotation is then no longer possible due to the locked and non-movable actuator 3 in this position.

Furthermore, the area 5.2 is biased by a spring 8 in the direction of the locked position. The first area 5.1 has for this purpose a projection 9 on which the spring 8 is mounted. At the other end, the spring 8 is connected to the second region 5.2. To improve the stability of the spring 8 and the connection of the spring 8 with the second region 5.2, this has a notch, in which the spring 8 is guided.

In the locked position according to Fig. 1 pushes the spring 8, the second area 5.1 upwards, so that the hidden by the screw head of the coupling element 6 stop 7.2 abuts the coupling element 6. A rotational movement of the actuating element 3 about the actuating rotational axis B in the in Fig. 2 shown unlocked position therefore causes the Notentkopplungsvorrichtung 5 and the closure element 4 to move accordingly. For a relative movement of the two areas 5.1, 5.2 or of the closure element 4 relative to the actuating element 3, it is due to the stop 7.1 in one direction and due to the clamping force the spring 8 in the other direction upon rotation of the actuating element 3 is not.

However, the emergency decoupling device 5 allows a relative movement about the relative axis of rotation R, when the closure element is actuated in the context of an emergency operation itself. This will be explained in more detail below.

In an emergency situation in which a person is locked in a room and the pivot lever 3.2 of the actuating element 3 on the other side of the sliding door 2 is unattainable, the closure element 4 can also be directly emergency operated and this be transferred from a locking position to an emergency unlocking.

For emergency unlocking, one must do this as shown in Fig. 1 downwardly directed force is exerted on the closure element 4. Such a force action on the closure element 4 leads to a rotational movement of the closure element 4 and of the second region 5.2 of the emergency decoupling device 5 about the relative rotational axis R. The second region 5.2 is moved relative to the non-moving first region 5.1 against the force of the spring 8, until the stop 7.1 abuts the coupling element 6 and so a further relative movement is prevented. In this emergency decoupling position, the closure element 4 has now been rotated so far that the hook-shaped end region no longer engages behind the frame-side locking element 10 and therefore movement of the sliding door 2 is no longer prevented. After the closure element 4 has been moved into the emergency unlocking position, it is sufficient to move the sliding door 2 a distance, so that when released the closure element 4 no longer engages behind the locking element 10, the sliding door 2 can then be completely opened and the space can be left.

Furthermore, the closure device 1 has a surcharge function, which allows the sliding door 2 locks automatically when it is closed. The closure element 4 has accordingly Fig. 4 a designed as a run-up slope 4.1 closing contour, which starts at a closing operation of the sliding door 2 against the arranged on the frame 11 locking element 10. The run-up slope 4.1 ensures that the closure element 4 moves automatically against the force of the spring 8 in such a closing movement, as shown in the illustration of Fig. 4 can be seen. Once the hook-like contour of the closure element 4 can engage behind the locking element 10, the closure element 4 in the direction of the force of the spring 8 upwards in the in Fig. 1 shown locked position in which the sliding door 2 can not be opened.

The aggregate function therefore enables a very simple locking of the sliding door 2, even without actuation of the actuating element 3.2 or even when the actuating element 3.2 is pivoted into the receiving contour 12. Furthermore, the deflection of the closure element 4 relative to the locking element 10 causes the forces acting on the closure device 1 forces are kept low and no destruction of the closure device 1 must be feared when slamming or closing the door 2.
