Description

[0001] Lock case and locking bolt for a locking system, locking system for locking a sliding door in a wall element, wall element and sliding door for a sliding door system, and sliding door system

[0002] Description

[0003] The invention relates to a lock case and a locking bolt for a locking system, a locking system for locking a sliding door in a wall element, a wall element for a sliding door, a sliding door, and a sliding door system comprising the wall element and the sliding door. The sliding door is an electrically operated sliding door that can be opened and closed, for example, by means of an electric drive. Furthermore, the sliding door system includes an electric locking system by means of which the closed sliding door can be locked in the wall element.

[0004] The sliding door system can be installed in a building that contains, for example, public and private spaces. For instance, a sliding door can separate a private room from a publicly accessible area. In the event of a power outage, the sliding door may no longer be able to be unlocked electrically. In such a situation, it may be crucial that one or more people can leave the private room through the designated opening with the sliding door open.

[0005] To ensure that a single person can open the sliding door in the event of a power outage, it is advantageous if that person has both hands free and, in particular, does not have to manually operate a release mechanism while opening the door. The problem, however, is that once permanently unlocked, the door is no longer locked and can subsequently be opened from both the inside and the outside. Therefore, in this case, there is no longer any burglar protection when the sliding door is unlocked. While the unlocking could be reversed with a simple release mechanism with a return spring, for example, this would require the release mechanism to be activated simultaneously with opening the sliding door, which, as implicitly mentioned above, can be disadvantageous.There may be a need for a lock case and a locking bolt for a locking system that allows the sliding door to be manually unlocked, manually opened (especially by one person using both hands), and automatically unlocked again during the opening process, so that the sliding door automatically locks again when subsequently closed. Furthermore, there may be a need for the locking system comprising the lock case and the locking bolt, a wall element comprising the lock case, a sliding door comprising the locking bolt, and a sliding door system comprising the wall element and the sliding door.

[0006] Such a need can be met by the object according to one of the independent claims. Advantageous embodiments are defined in the dependent claims and the following description.

[0007] One aspect of the invention relates to a lock case for a locking system. The locking system is designed for locking a sliding door in a wall element. The locking system comprises the lock case and a locking bolt for the sliding door. The lock case is designed for installation in the wall element and for receiving the locking bolt. The lock case includes: a locking lever rotatably mounted in a recess of the wall element, comprising a first lever arm and a second lever arm rigidly connected to each other, the first lever arm having a detent hook at its end furthest from the second lever arm, and the second lever arm having a first magnetic element at its end furthest from the first lever arm for interacting with a second magnetic element on the locking bolt of the sliding door;an axle element with which the locking lever is coupled between the first lever arm and the second lever arm, which is mechanically coupled to the wall element and by means of which the locking lever is rotatably mounted about an axis of rotation, wherein the first lever arm extends from the axis of rotation in a first direction and wherein the second lever arm extends from the axis of rotation in a second direction that differs from the first direction; and an actuating element which is arranged on the wall element in a manner accessible from the outside and which is mechanically coupled to the locking lever in such a way that when the actuating element is actuated, the locking lever is rotated about the axis of rotation.

[0008] The operating element can be designed in various ways. In an apartment, such an element can be barely noticeable. An example of such an inconspicuous design is a flap, preferably located near the floor and / or recessed into the wall element. Alternatively, the operating element can be more conspicuous, for example, in a hotel or a publicly accessible space. An example of a conspicuous design is a sphere, particularly one that is large and / or red and / or bright, protruding from the wall element. When the operating element is not in use, especially when not opened, both the operating element and the locking lever are in the closed position. If the sliding door is closed when the locking lever is in the closed position, the sliding door is locked in the wall element and cannot be opened.When the operating element is activated, particularly when it is opened, and consequently the locking lever rotates around its axis, the operating element and the locking lever are in the open position. In the open position of the locking lever, the sliding door is unlocked and can be opened manually. If the sliding door is at least partially open, for example, while being pushed open, the locking lever can be rotated back to the closed position without locking the sliding door, as the locking bolt is not yet far enough into the lock case.For example, the lock case can have a return spring which is designed and arranged in such a way that it exerts a return force on the locking lever in the direction of the closing position, so that the locking lever is pulled into the closing position unless an external force acts on and / or is transmitted to the locking lever, for example by a person operating the actuating element.

[0009] The first magnetic element, in conjunction with the second magnetic element, holds the locking lever in the open position at the beginning of the sliding movement using magnetic force, possibly against the restoring force of the return spring. This ensures that the locking lever remains in the open position initially without further or continued actuation of the actuator. Subsequently, when the sliding door is pushed open far enough that it can no longer be locked because the locking bolt has been pulled too far out of the lock case, and the sliding door is pushed open further, further rotation of the locking lever can be prevented, for example, by a corresponding stop in the lock case. This prevents the locking lever from following the locking bolt any further, causing the magnetic elements to separate and, due to the corresponding decrease in magnetic force, releasing the locking lever.The released locking lever can then be turned back into the closed position, for example by means of the return spring.

[0010] Thus, the unlocking mechanism can be "activated" by pressing the operating element. After unlocking, the sliding door can be manually pushed open. The unlocking mechanism remains engaged, or "active," until the sliding door is pushed open at least partially and the locking bolt is pulled out of the lock case. When the sliding door is pushed open further, allowing the person to leave the room, the locking lever is returned to its starting position, for example, by the return spring. This ensures that when the sliding door is subsequently closed, it can be locked again, especially automatically, and the unlocking mechanism is "deactivated." The person can therefore simply unlock the door without having to think about relocking it, as this happens automatically, ensuring burglary protection.

[0011] The first and second lever arms can be rigidly connected or formed as a single piece. The axle element can be rigidly connected to the first and / or second lever arm or formed as a single piece with the first and / or second lever arm. In this case, the axle element can be rotatably coupled to the wall element. Alternatively, the axle element can be rigidly connected to the wall element, in which case the first and second lever arms are rotatably coupled to the axle element.

[0012] The first magnetic element can have or consist of a magnetic material. The second magnetic element can have or consist of a magnetic material. If both magnetic elements have or consist of the magnetic material, the magnetic elements can be arranged such that the 2024P00020WQ

[0013] - 5 -

[0014] Magnetic elements attract each other. Alternatively, only one of the two magnetic elements can have or consist of the magnetic material, in which case the other magnetic element has a magnetizable material, for example ferromagnetic, so that one magnetic element attracts the other magnetic element.

[0015] The actuator can be positioned within an opening in the wall element. This opening can be located, for example, near the bottom, near the top, or approximately in the middle of the wall element. The actuator can be rotatably mounted within the opening. It can be designed and positioned so that, in its closed position, it is flush with an outer surface of the wall element. Optionally, the actuator can be held in its closed position by a spring or a magnet. This can contribute to pleasant tactile feedback when operating the actuator.

[0016] According to a further development, the end of the second lever arm facing away from the first is bent towards the first lever arm. Alternatively or additionally, the locking hook on the first lever arm can be bent towards the second lever arm. For example, the locking lever as a whole can have a curvature caused by a curvature of the first and / or second lever arm. In this case, the locking hook can protrude from the first lever arm towards the center of the curvature.

[0017] According to a further development, the actuating element is mechanically coupled to the locking lever by means of at least one rigid connecting element. The rigid connecting element can, for example, be a rod-, pin-, or hook-shaped element. The actuating element can have a fastening element on its inner side by means of which the rigid connecting element is mechanically coupled to the actuating element. The locking lever can have a further fastening element by means of which the rigid connecting element is mechanically coupled to the locking lever. The fastening elements can, for example, each have an eyelet or be designed as an eyelet.

[0018] Preferably, a hook-shaped connecting element engages in an eyelet on the

[0019] Locking lever. The play between the eyelet and the connecting element 2024P00020WQ can be adjusted.

[0020] - 6 - be set so that actuation of the actuator moves the locking lever, but that the movement of the locking lever, as is caused, for example, by closing the sliding door, is not transmitted to the actuator.

[0021] According to further training, the actuating element is mechanically coupled to the closing lever by means of a pull cord. The pull cord can be part of a Bowden cable. The pull cord can be attached to the actuating element or the closing lever using the fastening elements. The pull cord can be arranged in addition to or as an alternative to the rigid connecting element mentioned above. The pull cord serves to transmit a tensile force; it can be, for example, a rope, cable, cord, chain, rod, or band. The use of a pull cord also prevents the movement of the closing lever, such as that caused by closing the sliding door, from being transmitted to the actuator.

[0022] According to a further development, the locking lever has a pull lug by means of which the pull rod is mechanically coupled to the locking lever. The pull lug can, for example, be located on a side of the locking lever facing away from the detent hook. The pull lug can, for example, project from the rest of the locking lever in a direction opposite to that in which the detent hook extends. The pull lug can, for example, be located on the first lever arm. The pull lug can, for example, be located close to the axle element. The pull lug can include the fastening element for attaching the pull rod to the locking lever. For example, the corresponding eyelet can be formed in the pull lug.

[0023] According to a further development, the actuating element is mechanically coupled to the wall element by means of a detent mechanism. The detent mechanism is designed such that it holds the actuating element in its current position unless force is exerted on the actuating element by a person and / or the closing lever. For example, the actuating element can be rotatably arranged in the opening of the wall element about an actuating element axis, with the detent mechanism being arranged on the actuating element axis in such a way that it can hold the actuating element at least in the open position, possibly in the closed position, and optionally in one or more intermediate positions. For this purpose, the detent mechanism can have a first detent element attached to the 2024P00020WQ

[0024] - 7 -

[0025] The actuating element is arranged, and a second locking means is mechanically coupled to the wall element and can interact positively with the first locking means.

[0026] According to a further development, the locking lever is arranged such that the axis of rotation is vertically aligned. In this embodiment, the rotational movement of the locking lever takes place within a horizontal plane.

[0027] One aspect of the invention relates to the locking bolt for the locking system. The locking bolt is designed for installation on the sliding door and for insertion into the lock case. The locking bolt comprises: an end section at one longitudinal end of the locking bolt, wherein, in a standard arrangement of the locking bolt on the sliding door and the lock case in the wall element, the end section faces the lock case or is arranged within the lock case; a locking lug, which in the first end section is designed such that the detent hook of the first lever arm of the lock case can engage in the locking lug when the locking bolt is arranged in the lock case; and the second magnetic element, which is arranged on the end section, for interacting with the first magnetic element on the locking lever of the lock case.

[0028] The locking lug can be arranged on a locking element of the locking bolt. The locking element can be designed such that, in a first position of the locking element, the detent hook engages in the locking lug, and that in a second position of the locking element, the locking lug releases the detent hook. For example, the locking element can be rotatably arranged. In particular, the locking element can be designed so that it can be rotated from the first to the second position or from the second to the first position. Furthermore, the locking bolt can have a locking tab by means of which the locking element can be fixed so that it can no longer be rotated from the first to the second position.The locking tab can be mechanically coupled to an actuator so that the actuator can move the locking tab to engage or disengage the locking element. The actuator can, for example, be an electromagnet. Whether, in the intended arrangement of the locking bolt on the sliding door and the lock case in the wall element, the end section merely faces the lock case or is even located within it, depends on how far the sliding door is open. If the sliding door is open far enough that the locking bolt is outside the lock case, the end section faces the lock case but is not located within it. Alternatively, if the sliding door is closed far enough, for example, completely closed, the end section is located within the lock case.

[0029] Provided the sliding door operates correctly, the actuator can release the locking mechanism in the wall element, allowing the sliding door to be opened electrically using the drive unit, which may be an electric motor. If the sliding door does not operate correctly, and in particular if the drive unit is not functioning as intended, the locking mechanism in the wall element can be released using the actuator and the locking lever of the lock case, and the sliding door can then be opened manually.

[0030] According to further training, the closing lug is arranged on a first side of the first end section and the second magnetic element is arranged on a second side of the first end section facing away from the first side.

[0031] One aspect of the invention relates to the locking system for locking the sliding door in the wall element. The locking system comprises: the lock case as explained in more detail above and below; and the locking bolt as explained in more detail above and below, wherein the lever arms of the locking lever of the lock case and the two magnetic elements are arranged and designed such that, when the actuating element is unfolded, the first magnetic element adheres to the second magnetic element due to magnetic attraction and holds the locking lever in such a way that the sliding door is unlocked and can be slid open, and that in this situation, when the sliding door is slid open, the magnetic elements are separated from each other, thereby releasing the locking lever so that the sliding door can subsequently be locked again. 2024P00020WQ

[0032] - 9 -

[0033] According to a further development process, the lever arms of the locking lever of the lock case and the two magnetic elements are arranged and designed such that, when the sliding door, unlocked by magnetic force, is pushed open, the first magnetic element separates from the second magnetic element once the locking lug of the locking bolt has passed the detent hook of the locking lever. Once the locking lug of the locking bolt has passed the detent hook of the locking lever, the sliding door will not lock when the locking lever is turned back towards its closed position, for example, by means of the return spring. This allows the sliding door to be easily pushed open without the need to move or hold the operating element open again or continuously. This can contribute to particularly easy opening of the sliding door.

[0034] According to a further development process, the locking hook on the first lever arm of the lock case's locking lever and the locking lug of the locking bolt are designed such that, when the locking bolt is inserted as far as possible into the lock case, the locking lug is extended beyond the locking hook, creating a gap between the locking hook and the locking lug. For example, when the locking bolt is inserted as far as possible into the lock case, this gap can range from 1 mm to 10 mm, from 2 mm to 8 mm, or approximately 5 mm. This gap contributes to the smooth electrical opening of the sliding door. In particular, when the sliding door is opened electrically, the corresponding drive can initially push the sliding door further than theoretically required to relieve the pressure on the locking lug of the locking bolt, allowing the electromagnet to unlock the locking lug with minimal force.

[0035] One aspect of the invention relates to the wall element for the sliding door. The wall element comprises: the lock case, as explained in more detail above and below, which is arranged in the recess of the wall element such that, when the sliding door is arranged as intended in the wall element, the locking bolt of the sliding door can be inserted into the lock case in order to lock the closed sliding door in the wall element.

[0036] One aspect of the invention relates to the sliding door for the sliding door system. The sliding door has: the locking bolt as explained in more detail above and below, wherein the locking bolt is arranged on the sliding door such that, when the sliding door is arranged as intended in the wall element, the locking bolt can be inserted into the lock case of the wall element in order to lock the closed sliding door in the wall element.

[0037] One aspect of the invention relates to the sliding door system, comprising the wall element as explained in more detail above and below, which is arranged in a passageway in a building; and the sliding door as explained in more detail above and below, which is arranged in the wall element such that the closed sliding door can be locked to the wall element by means of the locking bolt of the sliding door and the lock case of the wall element.

[0038] It should be noted that some of the possible features and advantages of the invention are described herein with reference to only one of the aspects. However, a person skilled in the art will recognize that these features can readily be transferred to one or more of the other aspects in order to arrive at further embodiments of the invention and / or to achieve further advantages.

[0053] The figures are merely schematic and not to scale. Identical reference symbols in the different figures denote identical or equivalent features.

[0054] Fig. 1 shows an embodiment of a sliding door system 20 with a sliding door 24 and a wall element 22. The sliding door 24 is arranged in the wall element 22 and has a locking bolt 44. The wall element 22 has a lock case 42. The locking bolt 44 and the lock case 42 form a locking system 40 of the sliding door system.

[0055] The wall element 22 and the sliding door 24 can, for example, be arranged in a passageway in a building, the passageway being bordered by one or more wall elements 22. The sliding door 24 can be opened or closed to allow passageways to be opened or closed. The passageway in the building can lead, for example, from a private room, such as a private apartment, a medical practice, a law firm, or an office, to a public room, such as a hallway or a stairwell. The sliding door 24 is arranged in the wall element 22 such that the closed sliding door 24 can be locked to the wall element 22 by means of the locking bolt 44 of the sliding door 24 and the lock case 42 of the wall element 22.

[0056] The lock case 42 is arranged in the wall element 22 such that, when the sliding door 24 is closed, as shown in Figure 1, the locking bolt 44 of the sliding door 24 is inserted into the lock case 42, for example, to lock the closed sliding door 24 in the wall element 22. When the sliding door 24 is open, the locking bolt 44 is not in the lock case 42, but can be inserted into it by closing the sliding door 24. The sliding door 24 can be opened in an opening direction 32. The open sliding door 24 can be closed in a closing direction 34, which is opposite to the opening direction 32.

[0057] If the sliding door system 20 is in perfect working order and fully operational, the sliding door 24 can be opened and closed automatically. For this purpose, the sliding door system 20 can have an electric drive that is mechanically coupled to the sliding door 24 and is designed to open or close the sliding door 24 depending on its current control signal. In addition, the sliding door 24 can be automatically and / or electrically locked in the closed position, in particular by means of the locking system 40, as explained in more detail below.

[0058] If the sliding door system 20 is not in perfect working order and / or not fully functional, in particular if the drive for automatically opening and closing the sliding door 22 and / or the automatic locking system 40 are not functioning, for example due to a power failure, the sliding door 24 cannot be automatically unlocked, opened, or closed. In this case, the lock can be released manually. For this purpose, the locking system 40 has an actuating element 30. By actuating the actuating element 30, the sliding door 24 can be unlocked, as explained in more detail below. Subsequently, the sliding door 24 can be opened manually. For this purpose, the sliding door 24 may, for example, have a handle 26.Manually operating the actuating element 30 mechanically unlocks the sliding door system 20, in particular the locking system 40, as explained in more detail below. The actuating element 30 can be located on the wall element 22, for example, almost at the bottom, as shown in Figure 1, almost at the top (not shown), or approximately in the middle (shown with dashed lines).

[0059] Fig. 2 shows an embodiment of the locking system 40 with the lock case 42 and the locking bolt 44 in a first state. In the first state, the sliding door 24 is partially open, so that it is neither closed nor locked. In the first state, the locking bolt 44 is located outside the lock case 42, but is moved towards the lock case 42 due to a movement of the sliding door 24 in the closing direction 34.

[0060] The locking system 40 serves to lock the sliding door 24 in the wall element 22. The locking system 40 comprises the lock case 42 and the locking bolt 44. The lock case 42 is arranged in a recess 36 of the wall element 22. The lock case 42 is designed to receive the locking bolt 44. The lock case 42 comprises a locking lever 46, an axle element 54, and the actuating element 30. The locking lever 46 is rotatably arranged in the recess 36 of the wall element 22, specifically in the lock case 42. The locking lever 46 has a first lever arm 50 and a second lever arm 52. The lever arms 50 and 52 are rigidly connected to each other. The first lever arm 50 has a detent hook 62 at its end facing away from the second lever arm 52.The second lever arm 52 has a first magnetic element 60, which may, for example, be arranged and / or formed at an end of the second lever arm 52 facing away from the first lever arm 50. The first magnetic element 60 serves to interact with a second magnetic element 72 on the locking bolt 44 of the sliding door 24.

[0061] The axle element 54 is arranged between the first lever arm 50 and the second lever arm 52. The axle element 54 is mechanically coupled to the wall element 22. The closing lever 46 is rotatably mounted about a pivot axis 70 by means of the axle element 54. The first lever arm 50 extends from the pivot axis 70 in a first direction. The second lever arm 52 extends from the pivot axis 70. 2024P00020WQ

[0062] - 14 - in a second direction that differs from the first direction, for example, being essentially opposite to it. The actuating element 30 is arranged on the wall element 22 so that it is accessible from the outside and can be actuated, and is mechanically coupled to the closing lever 46 in such a way that when the actuating element 30 is actuated, the closing lever 46 is rotated about the axis of rotation 70.

[0063] The first and second lever arms 50, 52 can be rigidly connected to each other or formed integrally. The axle element 54 can be rigidly connected to the first and / or second lever arms 50, 52 or formed integrally with them. In this case, the axle element 54 can be rotatably coupled to the wall element 22. Alternatively, the axle element 54 can be rigidly connected to the wall element 22, in which case the first and second lever arms 50, 52 are rotatably coupled to the axle element 54. The locking lever 46 can be arranged such that the axis of rotation 70 is vertically oriented. In this embodiment, the rotational movement of the locking lever 46 takes place within a horizontal plane.

[0064] An end of the second lever arm 52 facing away from the first lever arm 50 can be bent towards the first lever arm 50. Alternatively or additionally, the locking hook 62 on the first lever arm 50 can be bent towards the second lever arm 52. For example, the locking lever 46 as a whole can have a curvature caused by a curvature of the first and / or second lever arm 50, 52. In this case, the locking hook 62 can project from the first lever arm 50 towards the center of the curvature.

[0065] The first magnetic element 60 can have or consist of a magnetic material. The second magnetic element 72 can have or consist of a magnetic material. If both magnetic elements 60, 72 have or consist of the magnetic material, they can be arranged such that they attract each other. Alternatively, only one of the two magnetic elements 60, 72 can have or consist of the magnetic material, in which case the other magnetic element 60, 72 has a magnetizable material, for example, ferromagnetic. 2024P00020WQ

[0066] - 15 -

[0067] Optionally, the lock case 42 can, for example, have a first return spring 56 which is mechanically coupled to the locking lever 46. In particular, the first return spring 56 can be designed and arranged such that it exerts a return force on the locking lever 46 in the direction of a closing position, so that the locking lever 46 is pulled into its closing position unless an external force acts on and / or is transmitted to the locking lever 46, for example by a person operating the actuating element 30.

[0068] The actuating element 30 is not actuated in the first state, in particular, it is not unfolded. In the first state, the actuating element 30 and the closing lever 46 are each in their closed position. The actuating element 30 can be arranged in an opening 36 of the wall element 22. The opening 36 can be located on the wall element 22, for example, almost at the bottom (see Figure 1), almost at the top (not shown), or approximately in the middle (see the actuating element shown with dashed lines in Figure 1). The actuating element 30 can be rotatably mounted in the opening 36 on the wall element 22, for example, by means of an actuating element pivot 96 (see Figure 12). The actuating element 30 can be designed and arranged such that an outer surface of the actuating element 30 is flush with an outer surface of the wall element 22 in its closed position.

[0069] The actuating element 30 can be mechanically coupled to the closing lever 46 by means of at least one traction element 58. The traction element 58 can be, for example, a rope, cable, cord, chain, flexible rod, or band. The actuating element 30 can have a fastening element 66 on its inner side, by means of which the traction element 58 is mechanically coupled to the actuating element 30. The closing lever 46 can have a further fastening element 66, by means of which the rigid traction element 58 is mechanically coupled to the closing lever 46. The fastening elements 66 can each, for example, have or be an eyelet.

[0070] The actuating element 30 can be mechanically coupled to the wall element 22 by means of a detent mechanism 68. The detent mechanism 68 can optionally be designed such that it holds the actuating element 30 in its current position unless a force is exerted on the actuating element 30 by a person and / or the closing lever 46.

[0072] The actuating element 30 is rotatably arranged in the opening 36 of the wall element 22 about an actuating element axis 97 (see Figure 12) of the actuating element 30, wherein the detent mechanism 68 is arranged on the actuating element axis 97 such that it can hold the actuating element 30 at least in its open position, possibly in its closed position, and optionally in one or more intermediate positions, as explained in more detail below with reference to Figure 12.

[0073] The actuating element 30 can have a signal color on its inner side, for example, red, yellow, or orange. This signal color allows for quick and easy identification of whether the actuating element 30 is actuated or not. Particularly when configured as a flap, the actuated flap, i.e., the open flap, exposes the inner side. If the signal color is visible from the outside, the actuating element 30 is actuated. If the signal color is not visible, the actuating element 30 is not actuated. Optionally, the actuating element 30 can be held in its closed position by means of a spring (not shown) or a magnet (not shown).

[0074] The locking bolt 44 is arranged on the sliding door 24. The locking bolt 44 is designed to be inserted into the lock case 42 and to subsequently lock the sliding door 24. The locking bolt 44 has an end section 71, a locking lug 48, and the second magnetic element 72. The end section 71 is located at a longitudinal end of the locking bolt 44 that, in the intended arrangement of the locking bolt 44 and the lock case 42 according to Figure 2, faces the lock case 42. The locking lug 48 is designed in the end section 71 such that the detent hook 62 of the first lever arm 50 of the lock case 42 can engage in the locking lug 48 when the locking bolt 44 is arranged in the lock case 42, as described in more detail below. The second magnetic element 72 is arranged at the end section of the locking bolt 44.

[0075] The locking lug 48 can be arranged on a locking element 47 of the locking bolt 44. For example, the locking lug 48 can be arranged on a first side of the end section 71, and the second magnetic element 72 can be arranged on a second side of the end section 71 facing away from the first side. The locking element 47 serves, among other things, to automatically unlock the sliding door 24, provided the locking system 40 is functioning correctly. 2024P00020WQ

[0076] - 17 -

[0077] The locking element 47 can be designed such that, in a first position of the locking element 47 (see, for example, Figures 2 to 4), the locking hook 62 can engage in the locking lug 48, and that in a second position of the locking element 47, the locking lug 48 releases the locking hook 62 (not shown). For example, the locking element 47 can be rotatably arranged, for instance, about a vertical axis parallel to the axis of rotation 70. In particular, the locking element 47 can be designed so that it can be rotated from the first to the second position or from the second to the first position. Furthermore, the locking bolt 44 can have a locking tab 74 by means of which the locking element 47 can be fixed so that it can no longer be rotated from the first to the second position, so that when the locking hook 62 is engaged, the sliding door 24 is locked in the wall element 24.The locking tab 74 can be mechanically coupled to an actuator such that the locking tab 74 can be moved by the actuator to engage or disengage the locking element 47. The actuator can, for example, include an electromagnet 76. The electromagnet 76 can be mechanically connected to the locking tab 74 by means of one or more lifting elements 78 to move it towards or away from the locking element 47.

[0078] The locking element 47 can be mechanically coupled to a second return spring 80. The second return spring can be coupled to the locking element 47 in such a way that it rotates the locking element 47 into its first position, for example, when the locking element 47 is in its second position.

[0079] Provided the sliding door 24 can be operated correctly, the actuator can release the locking mechanism of the sliding door 24 in the wall element 22, allowing the sliding door 24 to be opened electrically by means of the drive, which, for example, has an electric motor. During the opening process, the locking bolt 44 is pulled out of the lock case 42, and the locking element 47 is rotated due to the detent hook 62 engaging in the locking lug 48. If the locking system 40 does not function as intended, in particular if the actuator for moving the locking tab 74 does not function, the locking element 47 cannot be released, and the sliding door 24 cannot be unlocked. In this case, the locking mechanism of the sliding door 24 in the wall element 22 can be released by means of the actuating element 30 and the locking lever 46 of the lock case 42.

[0080] Fig. 3 shows the locking system 40 in a second state. In this second state, the sliding door 24 is not completely closed. However, in this second state, the sliding door 24 is closed at least to the extent that a substantial part of the end section 71 of the locking bolt 44 is located in the lock case 42. In particular, the locking bolt 44 is inserted into the lock case 42 to such an extent that the locking element 47 of the locking bolt 44 contacts the locking lever 46 of the lock case 42 and pushes and / or rotates it at least a short distance out of its closed position. However, during the closing movement of the sliding door 24 in the closing direction 34, the locking lug 48 of the locking element 47 has not yet passed the detent hook 62 of the locking lever 46, so that the detent hook 62 rests on the outside of the locking element 47 and cannot yet engage in the locking lug 46.In the second state, the locking bolt 44 can be inserted a little further into the lock case 42 in the closing direction 34.

[0081] Fig. 4 shows the locking system 40 in a third state. In this third state, the sliding door 22 is closed. Furthermore, the locking hook 62 has passed the locking lug 48 and engaged behind it. The locking lever 46 is in its closed position. The locking tab 74 secures the locking element 47 so that it cannot be rotated. Thus, the sliding door 24 is locked in the wall element 22 and cannot be opened.

[0082] Provided that the sliding door 24, in particular the actuator for unlocking the sliding door 24, in particular the electromagnet 76, functions properly, the locking tab 74 can be pulled in the opening direction 32 by means of the electromagnet 76, thereby releasing the locking element 47 and making it rotatable, as shown, for example, in Figures 2 and 3.

[0083] However, if the sliding door 24, in particular the actuator for unlocking the

[0084] If the sliding door 24, in particular the electromagnet 76, does not function properly, see 2024P00020WQ

[0085] - 19 - the locking tab 74 cannot be pulled in the opening direction 32 by means of the electromagnet 76, which is why the locking element 47 cannot be rotated and therefore cannot be released. In this case, the locking of the sliding door 24 can be released by means of the actuating element 30, as explained below.

[0086] Fig. 5 shows the locking system 40 in a fourth state. In this fourth state, the actuating element 30 is unfolded. For example, the actuating element 30 was unfolded by a person who wanted to unlock the sliding door 24. When the actuating element 30 is unfolded, the locking lever 46 rotates about the pivot axis 70. At the end of this rotation, the actuating element 30 and the locking lever 46 are in the open position shown in Fig. 5. In the open position of the locking lever 46, the sliding door 24 is unlocked and can be pushed open manually.

[0087] The lever arms 50, 52 of the closing lever 46 and the two magnetic elements 60, 72 are arranged and designed such that, when the actuating element 30 is unfolded, the first magnetic element 60 adheres to the second magnetic element 72 due to magnetic attraction and holds the closing lever 46 in such a way that the sliding door 24 is unlocked and can be slid open. For example, the magnetic elements 60, 72 can be arranged so that they touch each other in the fourth position. The closing lever 46 is then held in its open position due to the attractive force acting between the magnetic elements 60, 72, possibly against the restoring force of the first return spring 56.

[0088] The first magnetic element 60, in conjunction with the second magnetic element 72, thus enables the locking lever 46 to be held in the open position at the beginning of the sliding movement by means of magnetic force, so that initially the locking lever 46 remains in its open position and thus the unlocking remains “active” without further and / or continued actuation of the actuating element 30.

[0089] Thus, the unlocking mechanism can be "activated" by actuating the actuator 30. After unlocking, the sliding door 24 can be manually pushed open. The unlocking mechanism remains engaged after actuating the actuator 30 until the sliding door 24 is pushed open at least partially and the locking bolt 44 is accordingly pulled out of the lock case 42.

[0090] Fig. 6 shows the locking system 40 in a fifth state. In this fifth state, the sliding door 24 has been pushed open so far that the locking bolt 44 is pulled out of the lock case 42 to such an extent that the locking lug 48 has already passed the detent hook 62. In particular, a projection of the detent hook 62 onto the locking element 47 shows a first distance 86 from the locking lug 46. If the locking lever 46 is now turned back towards its closed position, the detent hook 62 can no longer engage behind the locking lug 48, thus unlocking the sliding door 24. Therefore, the sliding door 24 is not locked when the locking lug 46 has passed the detent hook 62 and when the locking lever 46 is turned back to its initial position, for example by means of the first return spring 56.

[0091] The lock case 42, and in particular the locking lever 46, are designed such that the locking lever 46 cannot be rotated beyond its open position from its closed position. For example, the lock case 42 can have a wall designed such that the locking lever 46 abuts the wall in the fifth position and cannot be rotated further. Optionally, the lock case 42 can have a dedicated stop (not shown) for the locking lever 46 for this purpose.

[0092] Fig. 7 shows the locking system 40 in a sixth state. In this sixth state, the sliding door 24 is pushed open so far that the locking lever 46 can no longer follow the locking bolt 44 due to the wall or stop of the lock case 42, and the magnetic elements 60, 72 have separated from each other. Furthermore, the gap between the two magnetic elements 60, 72 is so large that the magnetic force is insufficient to hold the locking lever 46 in its open position, so that the locking lever 46 is released. In particular, the locking lever 46 is rotated back towards its closed position, for example as a result of the restoring force acting on it by the first return spring 56.In the sixth state, however, the locking hook 62 cannot engage in the locking lug 48, but can only rest against the locking element 47, as visually highlighted in Figure 7 by the small circle on the locking hook 62, since the locking bolt 44 does not extend far enough into 2024P00020WQ.

[0093] - 21 - is located in the lock case 42. Therefore, the sliding door 24 is not locked in the sixth position.

[0094] Thus, the lever arms 50, 52 of the locking lever 46 and the two magnetic elements 60, 72 are arranged and designed such that, when the sliding door 24, unlocked by magnetic force, is pushed open, the first magnetic element 60 only detaches from the second magnetic element 72 once the locking lug 46 has passed the detent hook 62. This allows the sliding door 24 to be pushed open further without the need to move or hold the actuating element 30 open again or continuously. This can make opening the sliding door 24 particularly easy, as the person now has both hands free to open the door.

[0095] Fig. 8 shows the locking system 40 in a seventh state. In this seventh state, the sliding door 24 is pushed open so far that the locking bolt 44 is pulled out of the lock case 22 to such an extent that the locking bolt 44 no longer makes contact with the locking lever 46. The locking lever 46 is fully returned to its closed position, for example by means of the first return spring 56. Due to the mechanical coupling between the locking lever 46 and the actuating element 30, in particular due to the pull rod 58, the locking lever 46 also pulls the actuating element 30 back into its closed position. The first return spring 56 must be selected such that its spring force, in particular its return force, is sufficient to pull the locking lever 46 and the actuating element 30 into their respective closing positions, if necessary against the holding force of the detent mechanism 68.Once the locking lever 46 is in its locking position, the sliding door 24 can be automatically locked again when it is closed and the locking bolt 44 is inserted sufficiently far into the lock case 42, as explained, for example, with reference to Figure 4.

[0096] Thus, when the sliding door 24 is pushed open further, particularly to the point where the person can leave the room, the locking lever 46 is turned back to its initial position, for example by means of the first return spring 56, so that when the sliding door 24 is subsequently closed again, it can be locked again, in particular automatically. The person can thus close the sliding door 2024P00020WQ

[0097] - 22 -

[0098] 24 simply unlock without having to think about relocking afterwards, as this happens automatically and burglary protection is guaranteed.

[0099] Fig. 9 shows an alternative embodiment of the locking system 40 in its seventh state. In this alternative embodiment, the locking lever 46 is mechanically coupled to the actuating element 30 by means of a further pull member 58b. The further pull member 58b can be part of a Bowden cable. The pull member 58b can be attached to the actuating element 30 or the locking lever 46 by means of the fastening elements 66. The pull member 58b can be arranged in addition to or as an alternative to the rigid pull member 58 mentioned above.

[0100] Optionally, the locking lever 46 can have a pull lug 64 by means of which the pull element 58 is mechanically coupled to the locking lever 46. The pull lug 64 can, for example, be arranged on a side of the locking lever 46 facing away from the detent hook 62. The pull lug 64 can, for example, project from the rest of the locking lever 46 in a direction opposite to that in which the detent hook 62 extends. The pull lug 64 can, for example, be arranged on the first lever arm 50. The pull lug 64 can, for example, be arranged close to the axle element 54. The pull lug 64 can have the fastening element 66 for attaching the pull element 58 to the locking lever 46. For example, the corresponding eyelet can be formed in the pull lug 64.

[0101] Fig. 10 shows a detailed view of the locking system 40 in an eighth state. In this eighth state, the locking bolt 44 is inserted as far as possible into the lock case 42. In this eighth state, the locking bolt 44 is inserted further into the lock case 42 than would be necessary to engage the detent hook 62 behind the locking lug 48. In particular, the detent hook 62 has a second distance 90° from the locking lug 48. Thus, the detent hook 62 and the locking lug 48 can be designed such that, when the locking bolt 44 is inserted as far as possible into the lock case 42, the locking lug 48 is extended beyond the detent hook 62, such that the detent hook 62 is spaced apart from the locking lug 48. For example, if the locking bolt 44 is inserted as far as possible into the lock case 42, the second distance 90 can be in a range of 1 mm to 10 mm, for example from 2 mm to 8 mm, for example at approximately 5 mm.The second distance of 90 can lead to a flawless electrical 2024P00020WQ.

[0102] - 23 -

[0103] Contribute to opening the sliding door 24. In particular, when the sliding door 24 is opened electrically, the corresponding drive can initially push the sliding door 24 further closed than it would theoretically need to be in order to relieve the locking lug 48 on the locking bolt 44, so that the electromagnet 76 can unlock the locking lug 48 with almost no force.

[0104] Fig. 11 shows an alternative embodiment of the locking lever 46 and the actuating element 30 of the locking system 40. In this alternative embodiment, a connecting element 88 replaces the pull element 58 of Figures 2 to 10. In particular, the connecting element 88 has a loop 92, which is, for example, rigid, and a hook element 94, which is, for example, rigid. The hook element 94 is hooked into the loop 92. The loop 92 is arranged on the first lever arm 50. The hook element 94 is arranged on the actuating element 30. Alternatively, the hook element 94 can be arranged on the first lever arm 50 and the loop 92 on the actuating element 30. Or the hook can engage directly, for example, on the tactile hook 62 on the locking lever 46. Thus, for example, the loop 92 can be omitted.

[0105] In the proper functioning of the sliding door 24, the closing lever 46 is rotated slightly during each closing operation of the sliding door 24 due to the closing lug 46 passing over it (see second state, Figure 3). The loop 92 and the hook element 94 can be designed such that this slight rotation results only in a relative movement between the loop 92 and the hook element 94, and no force is transmitted to the actuating element 30, so that the actuating element remains closed during normal operation of the sliding door system 20. Only when the actuating element 30 is manually actuated from outside the wall element 22 can the corresponding opening movement be large enough for the hook element 94 to contact the loop 92 and transmit the force to the closing lever 46.Thus, the connection between the actuating element 30 and the closing lever 46 is unloaded or at least almost unloaded in the proper operation of the sliding door system 20.

[0106] Fig. 12 shows an embodiment of the locking mechanism 68 of the lock case 42. The actuating element 30 is rotatable in the 2024P00020WQ by means of the actuating element pivot 96.

[0107] - 24 -

[0108] The actuating element 30 is mounted in the opening 38 of the wall element so that it can rotate about an actuating element axis 97. The actuating element pivot 96 can be at least partially enclosed by a body having a first detent element 98. The first detent element 98 can, for example, have or consist of several indentations that define different detent positions. A second detent element 100 can be mechanically coupled to the wall element 22, for example, indirectly or directly connected to it. The second detent element 100 is designed to interact with the first detent element 98 to implement the detent mechanism 68. The second detent element 100 can, for example, have or be a detent lug that is designed and arranged so that it can engage in the indentations depending on a rotation of the actuating element 30. The first detent element 98 and the second detent element 100 can thus interact positively.

[0109] Finally, it should be noted that terms such as "comprising," "encompassing," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps from other embodiments described above. Reference numerals in the claims are not to be considered as limitations.
