Definitions

  • the present invention relates to a locking device for a door, in particular for a sliding door, with at least one door leaf to be locked or released.
  • the invention also relates to a door with such a locking device.
  • Sliding doors with at least one, often two, sliding door leaves have been known for a long time.
  • the door leaf or leaves can usually be moved perpendicularly to a passage direction in such a way that a passage can be released or closed, for example, through a wall opening in a building.
  • automatic sliding doors are also known in which the door leaf or leaves do not have to be moved by hand to open and close, but this is accomplished by a drive motor.
  • a presence sensor can be provided on both sides of the sliding door in order to cause the sliding door to open automatically as soon as a person approaches it.
  • CN 102127994 A discloses a locking device which has a locking lever which is provided with hook-shaped ends and which can be tilted for unlocking.
  • the tilting can on the one hand automatically by means of a Electromagnet and on the other hand be effected by hand by means of a cable.
  • the locking device disclosed in CN 211691917 U has an electromagnet with which a locking element can be lowered towards the door leaves for locking or raised for unlocking. Manual unlocking is possible with the help of an unlocking bolt, which causes the locking element to be raised.
  • FR 2 919 885 A1 discloses a locking device with an electromagnet, with which a locking element can be pushed towards the door leaves against a spring force in order to effect locking. By sliding, a metal disc comes into contact with a suction cup, which keeps the lock in place even after the electromagnet is switched off. In the event of a power failure, the lock can be released manually using a cable attached to the locking element.
  • DE 19835678 A1 discloses an electrical locking device for sliding door leaves, in which a locking element can be tilted between an open and a closed position. This can be achieved for manual unlocking by turning an actuating knob attached to the locking element via an axis. Alternatively, unlocking and locking can also be carried out by means of an electromagnet, which also causes the locking latch to rotate.
  • a disadvantage of the locking devices of the above-mentioned documents is that the locking element remains in its current position in the event of a power failure. This can be devastating in the event of a power failure caused by a fire, for example, since the door then has to be locked, for example to prevent the spread of fire, or opened automatically to allow people fleeing to pass through.
  • the door can only be opened or closed automatically using a motorized door drive or a purely mechanical, for example spring-operated, emergency drive if this is also made possible by the locking device.
  • the above-mentioned locking devices have the disadvantage that in the event of a malfunction, in particular jamming, of the electrotechnical part or the part of the manual operation, the other part in each case is also blocked as a result. It This can result in the situation that the door can no longer be opened, even in an emergency.
  • the locking device should preferably enable both automatic and manual locking and unlocking and, in addition, should advantageously be able to assume a predefined state in the event of a power failure.
  • claim 13 specifies a door with such a locking device. Further embodiments are given in the dependent claims.
  • the present invention therefore provides a locking device for a door, in particular for a sliding door, with at least one door leaf, having a housing part, a locking element held by the housing part, which is used to lock and unlock the at least one door leaf in a closed or open position.
  • the locking element can be displaced relative to the housing part both along a displacement direction and tilted about an axis of rotation in order to enable locking and unlocking of the at least one door leaf alternatively both by sliding and by tilting the locking element.
  • the locking element can be displaced along the displacement direction and, on the other hand, it can be tilted about the axis of rotation.
  • the locking device can be manufactured in a particularly simple and nevertheless very flexible manner.
  • the displacement and tilting of the locking element can be provided for different locking and unlocking purposes.
  • an automatic, ie for example electrotechnical, pneumatic or hydraulically based, locking and unlocking can cause a displacement of the locking element and a hand mechanism for manual locking and unlocking can cause the locking element to tilt—or vice versa.
  • the locking device in such a way that, in the event of an unexpected power failure, it assumes a predetermined state, ie in particular a locking or releasing state.
  • a predetermined state ie in particular a locking or releasing state.
  • spring elements and/or holding elements such as end position magnets, can be provided for this purpose, which bring the locking element into the desired predetermined position in the event of a power failure or hold it in the position already assumed.
  • Locking and unlocking is preferably possible on the one hand both by means of a pure displacement of the locking element and on the other hand by means of a pure tilting of the locking element.
  • the axis of rotation, about which the locking element can be tilted, preferably extends parallel to the direction of displacement and advantageously through the housing part.
  • the axis of rotation is particularly preferably defined by a rod-shaped element around which the locking element can be tilted, ie rotated.
  • the rod-shaped element is preferably a push rod which can be displaced along its longitudinal direction in order to thereby displace the locking element along the displacement direction. This makes the production of the locking device particularly simple.
  • the door is preferably a sliding door, with the locking element even more preferably serving to firmly connect two door leaves of the sliding door to one another for locking purposes.
  • the locking element preferably has a clamp-shaped, in particular C-shaped element, which in the locked state forms a stop for a stop element attached to the respective door leaf.
  • the stop elements of the two door leaves are preferably each arranged inside the clamp-shaped element in the locking state along the opening direction of the sliding door leaf and are thereby prevented from being separated from one another. The two door leaves can then not be moved away from each other, which means that the sliding door is locked.
  • the stop elements of the two door leaves can, for example, be elements that protrude upwards or in the passage direction, such as hooks, bolts, pins or blocks, which preferably each have a stop surface pointing in the opening direction, which in the locked state serves to stop on the locking element.
  • the locking device can also be used to lock a sliding door with only one door leaf.
  • the locking device which is also preferably stationary in other embodiments, can then form a stop for only one door leaf in the locked state, in order to prevent the same from being displaced.
  • the locking element preferably forms two or more stops, in particular exactly two stops, which serve to prevent the door leaves from sliding in the locked state.
  • the locking element preferably forms one or more such stops, in particular exactly one such stop.
  • the door does not necessarily have to be a sliding door, even if this is preferred.
  • the specified locking device can also be used for wing doors or revolving doors.

  • the direction of displacement, along which the locking element can be displaced back and forth relative to the housing part, which is preferably arranged in a stationary manner, preferably extends parallel to the passage direction of the door. Furthermore, the direction of displacement advantageously extends perpendicularly to the direction along which the at least one door leaf can be displaced in order to close or open the door opening.
  • the locking device also has a torsion spring, which exerts a torsional force directed about the axis of rotation on the locking element in order to keep the locking element in a state that locks or releases the at least one door leaf.
  • the torsional force brought about by the torsion spring serves in particular preferably to keep the locking element in the locking state and/or to bring it into this state. In this case, the locking element can thus be tilted and brought into the releasing state by overcoming the torsional force.
  • the locking device also has a compression spring which exerts a compressive force on the locking element in order to keep the locking element in a state that locks or releases the at least one door leaf and/or to bring the locking element into one of these states.
  • the locking element is thus preferably acted upon by the compression spring with a corresponding compressive force.
  • the compression spring preferably serves to displace the locking element along the direction of displacement and/or to hold it in its position along the direction of displacement.

  • the locking device a combined compression and torsion spring, which exerts a compression force and a torsion force on the locking element in order to keep the locking element in a state that locks or releases the at least one door leaf.
  • the combined compression and torsion spring which can in particular be designed as a spiral spring, therefore advantageously has the function of both the compression spring specified above and the function of the torsion spring specified above.
  • the locking element for unlocking the at least one door leaf can be tilted about the axis of rotation against the torsional force which is exerted on the locking element by the combined compression and torsion spring.
  • the torsional force exerted by the combined compression and torsion spring thus preferably keeps the locking element in a locking state.
  • the locking element for unlocking the at least one door leaf can be displaced along the displacement direction against the compressive force exerted by the combined compression and torsion spring.
  • the locking device may be designed to maintain the previously assumed state with regard to unlocking or locking in the event of a power failure, or else to assume a predetermined state.
  • one or more holding elements such as in particular one or more end position magnets, are preferably provided, which hold the locking element in the displacement position just assumed even in the event of a power failure.
  • the end position magnet or magnets can in particular each be permanent magnets.
  • the compressive force exerted by the compression spring in particular the combined compression and torsion spring, can serve to keep the locking element in a locked state and/or bring it into a locked state in the event of a power failure.
  • the locking element In the event of a power failure, the locking element can automatically assume the locking state due to the spring force.
  • the locking element for locking the at least one door leaf moves along against the compressive force exerted by the combined compression and torsion spring the displacement direction is displaceable.
  • the compressive force exerted by the compression spring in particular by the combined compression and torsion spring, can serve to keep the locking element in a releasing state and/or bring it into a locking state in the event of a power failure. In the event of a power failure, the locking element can automatically assume the releasing state due to the spring force.
  • the locking device preferably also has a displacement device.
  • the displacement device is preferably an electromagnetic displacement device.
  • the displacement device can in particular have a lifting magnet.
  • the displacement of the locking element can be implemented in a particularly simple manner with the aid of a lifting magnet. Instead of a lifting magnet, the use of another electromagnetic element is also conceivable.

However, if the sliding door 10 is to be locked when the door leaves 11 are in the closed position, the lifting magnet 7 is subjected to a reverse voltage, so that it exerts a force on the push rod 71 in a forward direction.
