EP3441551B1 - Device with an openable element - Google Patents

Description

The invention relates to a device with an element that can be opened, for example, by displacement, in particular a sliding gate device, comprising the openable element such as a sliding gate, a drive for opening the element and a lock, the drive opening the element by actuating the lock in a first operating position.

Devices such as sliding gates are known from the prior art which have openable elements which are equipped with a drive for opening. The drive usually comprises a motor, in particular an electric motor. In addition, the drive comprises additional components such as a toothed rack, in which a gear driven by the motor engages, so that the element can be opened when the motor is activated or, if necessary, also closed in the opposite direction.

In devices such as sliding gates, key switches and key switches are known with which an electric door drive can be started. The corresponding lock is mounted on or near the gate for this purpose.

Lockable mechanical locks are also known for sliding gates and similar devices with openable elements. In this case, a lock is also mounted on or near the gate. The gate can be opened when the lock is operated.

Devices are also known which have the aforementioned key switch or key switch for the electric door drive for basic operation, but also have a separate lock for any mechanical operation of the door. However, it is disadvantageous that two keys for two locks usually have to be carried. In addition, the installation locations for the two locks are located at different points. This leads to cumbersome operation.

An example of such a device is from EP 1 074 689 A2 known. From the WO 2010/075603 A1 , EP1 074 689 A2 and FR 3 008 731 A1 further devices are known which can be opened both by motor and mechanically.

This is where the invention comes into play. The aim of the invention is to enable easier operability.

This goal is achieved with a device having the features of main claim 1.

An advantage achieved with the invention is that a single lock is sufficient to either activate the drive automatically, for example a drive with an electric motor, or alternatively the element can be decoupled from the drive via the same lock so that the element can be opened manually can. All that is required is a single key and a single installation position for the lock.

If, for example, it is a sliding gate, if an electric motor fails or it does not react, the element can be easily decoupled from the drive and quickly opened manually.

A solution according to the invention is of course not only applicable to linearly displaceable sliding gates, but is also suitable for pivotably opened gates and in general all those devices in which an element locked in a rest position is to be opened by a linear and / or pivoting movement.

The drive of a device according to the invention generally comprises a motor, in particular an electric motor. The motor alone is not yet sufficient to move the element, but further components are required for the drive, for example a toothed rack which interacts with a toothed wheel connected to the motor. Alternative types of drive are also possible within the scope of the invention. For example, the motor does not have to be positioned in a stationary manner, but can be attached to the openable element and, for example, cause the element to move via a cable pull. In any case, however, the drive can be decoupled from the element in the second operating position, so that no manual locking of the drive prevents manual movement of the element. In particular, the drive can be unlocked by decoupling a gear that interacts with the motor, for example by linear displacement of a gear.

If a motor is provided, it can be connected to the lock by a traction device. The drive can then be decoupled or unlocked by activating the second operating position using the traction mechanism.

The lock comprises a lock cylinder and a key, the first operating state and the second operating state being able to be activated by the key. In this case, it can be provided, in particular for simple operation, that the first operating state can be activated by turning the key in a first direction and the second operating state can be activated by turning it in a second direction. The corresponding directions of rotation can also be marked on the lock. This makes it possible in a simple manner to select the respective operating position by turning the key to the left or right.

In this context, it is also provided that the lock cylinder is connected to a release device which, depending on the first operating state or the second operating state, either triggers an automatic opening of an element or an unlocking of the element from the drive. According to the invention, the triggering device is designed as a displaceable toothed rack and a toothed wheel cooperating with the toothed rack is arranged on the lock cylinder, so that the toothed rack can be shifted for the alternative choice of the first operating state or the second operating state. For example, an electrical contact can be provided which triggers automatic opening of the element and is triggered by linear displacement of the rack when the key is turned into the first operating position. When the key is turned in the other direction, the rack also moves linearly, but in the opposite direction. The second operating state in which the element is unlocked from the drive is then selected.

Depending on the course of the rack position, additional control options can also be implemented.

Although a toothed rack is particularly suitable for the release device, a winding spool can also be present in an alternative embodiment not according to the invention, so that with one or several turns of the key the unlocking is effected by a pulling action of the wound rope or the like.

In Figs. 1 to 4 a lock 1 according to the invention is shown. The lock 1 is particularly simple and has a lock leaf 6, in the center of which a lock cylinder 2 is inserted. The lock cylinder 2 closes on the front side, as can be seen, approximately flush with the lock plate 6. On the rear side, that is to say the rear side of the lock plate 6, the lock cylinder 2 has a peg-shaped extension on which a gearwheel 5 is arranged. The gearwheel 5 interacts with a toothed rack 4 which, for this purpose, is designed with a corresponding profile in a central area thereof. The toothed rack 4 is formed with the two end-side areas 41 and 42 over the profiled area that interacts with the gearwheel 5. The area 41 has a nose 43. The area 42 has a connection 44, to be explained in more detail, for a traction means or the like. In the exemplary embodiment, this connection 44 is designed as an eyelet. Furthermore, an electrical button 7 is provided, which is electrically connected to a drive, the drive comprising an electric motor. A push button 71 of the button 7 can be actuated by moving the rack 4, in which the nose 43 presses the push button 71. To do this, the rack 4 must be moved downwards. The already mentioned eyelet 44 is connected to a motor of the drive via a traction device. If the rack 4 is moved upwards, the traction means coupled in the eye 44 causes a motor to be unlocked.

The lock 1 is part of a device which additionally comprises an openable element (not shown) and a drive for opening the element. Here For example, it can be a sliding door with a linearly movable door leaf. In general, the lock 1 can be used in devices which comprise an openable element, a drive comprising a motor and further drive components being provided for opening the element. The button 7 is in operative connection with the motor, in particular an electric motor, so that when the push button is actuated, the motor is activated and the openable element opens automatically. When using a lock 1, it is also possible to decouple the drive by activating the rack 4 so that the element can also be opened mechanically or manually. To activate it, a key is inserted into lock 1 and, as in Fig. 1 indicated, turned to the right. As a result, the rack 4 is moved downwards until finally the nose 43 actuates the push button 71 of the button 7. When the push button is pressed, the motor receives a signal and starts, so that the element is opened. If the element does not open for various reasons, for example due to a lack of power supply to the motor, it can be turned in the opposite direction without removing the key. As a result, the rack 4 is moved in the opposite direction. The push button 71 is released again, but then the pulling means attached to the connection 44 or the eyelet is moved upwards, as a result of which the drive is unlocked. As a result, the element can be opened manually because there is now no mechanical inhibition. It is thus possible in a simple manner to achieve simple operation with a single lock 1 even if there is a malfunction in a first operating position (automatic electrical operation) and manual opening is desired in a second operating position.
