Locking device for a door
The invention relates to a locking device ( 1 ) for a door, in particular for a sliding door ( 10 ), comprising at least one door leaf ( 11 ). The locking device has a housing part ( 2 ) and a locking element ( 5 ) which is held by the housing part ( 2 ) and which is used to lock and unlock the at least one door leaf ( 11 ) in a closed or open position. The locking element ( 5 ) can be slid along a sliding direction (V) and can be tilted about a rotational axis (R 1 ) relative to the housing part ( 2 ) in order to allow the at least one door leaf ( 11 ) to be locked and unlocked alternatively by both sliding as well as by tilting the locking element ( 5 ). The invention additionally relates to a door, in particular a sliding door ( 10 ), comprising such a locking device ( 1 ).
1 . A locking device for a door, with at least one door leaf, comprising
a housing part,
a locking element held by the housing part, which is configured to lock and unlock the at least one door leaf in a closed or open position,
wherein the locking element is both slidable relative to the housing part along a sliding direction and tiltable about a rotational axis to allow locking and unlocking of the at least one door leaf alternatively, both by means of sliding and also by means of tilting of the locking element, and
wherein the locking element comprises an engaging element which extends parallel to the sliding direction and which is configured to engage a locking hook attached to the at least one door leaf when locking.
2 . The locking device as claimed in claim 1 , also comprising a compression spring and a sliding device, in order to slide the locking element against the compressive force of the compression spring along the sliding direction.
3 . The locking device as claimed in claim 2 , wherein the sliding device has an activated state, in which the sliding device holds the locking element in a releasing state or in a locking state.
4 . The locking device as claimed in claim 1 , also comprising a torsion spring and a tilting device, in order to tilt the locking element against the torsional force of the torsion spring about the rotational axis.
5 . The locking device as claimed in claim 4 , wherein the tilting device includes an actuating element that is pivotable about a second rotational axis that extends perpendicular to the first rotational axis, about which the locking element is tiltable.
6 . The locking device as claimed in claim 1 , also comprising a combined compression and torsion spring that is configured to apply both a compressive force along the sliding direction and a torsional force about the rotational axis to the locking element.
7 . The locking device as claimed in claim 1 , also comprising one or more holding elements, in order to hold the locking element in a releasing state and/or in a locking state.
8 . The locking device as claimed in claim 1 , wherein the locking element is slidable automatically by means of a sliding device and manually tiltable by a user, or is tiltable automatically by means of a tilting device and manually slidable by a user.
9 . The locking device as claimed in claim 8 , wherein at least one Bowden cable is provided, in order to manually tilt or slide the locking element.
10 . The locking device as claimed in claim 1 , wherein the engaging element is configured to be selectively arranged on the locking element in such a manner that the engaging element extends outwards from either the front or the back of the locking element with respect to the sliding direction.
11 . The locking device as claimed in claim 1 , wherein the locking device has a compact design as a whole.
12 . The locking device as claimed in claim 1 , wherein the locking device is configured to lock a sliding door.
13 . The locking device as claimed in claim 2 , wherein the sliding device includes a solenoid.
14 . The locking device as claimed in claim 7 , wherein the one or more holding elements are in the form of one or more end position magnets.
15 . The locking device as claimed in claim 1 , wherein the one or more engaging elements are in the form of one or more engaging pins.
16 . The locking device as claimed in claim 1 , comprising a second door leaf and wherein the locking element comprises a second engaging element which extends parallel to the sliding direction and which is configured to engage a second locking hook attached to the second door leaf when locking the sliding device.
17 . A door with at least one door leaf and a locking device to lock the at least one door leaf in a closed or open position, the locking device comprising
a housing part,
a locking element held by the housing part, which is configured to lock and unlock the at least one door leaf in the closed or open position,
wherein the locking element is both slidable relative to the housing part along a sliding direction and tiltable about a rotational axis to allow locking and unlocking of the at least one door leaf alternatively, both by means of sliding and also by means of tilting of the locking element, and
wherein the locking element comprises an engaging element which extends parallel to the sliding direction and which is configured to engage a locking hook attached to the at least one door leaf when locking.
18 . The door as claimed in claim 17 , wherein a locking hook is attached to each of the one or more door leafs, which locking hook is designed to engage the locking element in a direction perpendicular to the sliding direction.
19 . The door as claimed in claim 18 , wherein the locking hook(s) each has/have an inclined surface that is configured to abut against the locking element during closing or opening of the respective door leaf, in such a manner that it is tilted.
20 . The door as claimed in claim 17 , wherein the door is a sliding door.
21 . The door as claimed in claim 17 , comprising a second door leaf and wherein the locking element comprises a second engaging element which extends parallel to the sliding direction and which is configured to engage a second locking hook attached to the second door leaf when locking the sliding device.
