Description

[0001] The invention relates to a locking system for a door with the features of claim 1. Furthermore, the invention relates to a door arrangement with the locking system.

[0002] Sliding locks for doors are known which are characterized by a locking mechanism in which a locking action takes place at a location remote from an actuating part. For example, the actuating part is connected to the locking part via a transmission part, e.g., a rod, bar, etc., whereby the locking part can be locked or unlocked at a locking point when the actuating part is actuated via the transmission part.

[0003] Document 24 25 092 A1 discloses a locking rod for doors, windows or the like, with at least one bolt tongue pivoting out of an opening in the faceplate, which can be actuated by the locking rod, wherein the locking tongue is seated on a pivot pin that can be moved with the locking rod and has control edges which, in conjunction with edge edges of the faceplate opening, convert the longitudinal movement of the locking tongue into a pivoting movement of the same, wherein the pivot pin is located on the inner surface of a bridge-shaped bend in the locking rod in front of a window-shaped opening in the locking rod which serves to pivot in the bearing end of the locking tongue.

[0004] The publication EP 0 411 271 A1 discloses a rod lock with an auxiliary lock controlled by a central lock, which has a bolt that engages in a hook-like manner with the strike plate. In order to effectively absorb the recoil forces acting on the bolt when it is closed in the locked position, a cam-type control mechanism for the bolt is provided, which divides the bolt's path of movement into different sections, such that a control pin of the bolt is first guided in a slot diagonal to the direction of movement of the rod to achieve the hook engagement with the strike plate and then enters a slot section parallel to the direction of movement of the rod.

[0005] The publication EP 2995755 A1 discloses a locking device for arrangement on a door. The locking device comprises an actuator which is arranged to be linearly movable along a first axis, and a locking clamp for engaging a locking element on a door frame, wherein the locking clamp is flexibly coupled to the actuator such that when the actuator is moved along the first axis, the locking clamp moves linearly along the first axis and rotates about a pivot axis to allow engagement with the locking element.

[0006] The invention is based on the objective of creating a locking system which is characterized by a compact design.

[0007] This problem is solved by a locking system with the features of claim 1 and a door arrangement with the features of claim 12. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and / or the accompanying figures.

[0008] The invention relates to a locking system designed and / or suitable for a door. In particular, the locking system is designed as a remote locking mechanism which, when actuated, locks the door at a locking point remote from an actuating point.

[0009] The locking system comprises an actuating device and a locking device. Specifically, the actuating device is located at the actuation point and the locking device at the locking point. Preferably, actuation of the actuating device at the actuation point results in the locking of the locking device at the locking point.

[0010] The actuating device can be designed as a mechanical, electrical, or electromechanical actuating device. In particular, the actuating device can be operated and / or locked manually, e.g., by means of a key, or wirelessly, e.g., by means of RFID, or electrically, e.g., by means of a combination lock. The actuating device has a movable actuating element. In particular, the actuating element forms a connection interface for connecting the locking device to the actuating device.

[0011] The locking device comprises at least one locking element. In particular, the locking element serves to lock the door at the locking point. For this purpose, the locking element is pivotable about a pivot axis between a locking position and an unlocking position. Specifically, in the locking position, the locking element is engaged with one locking partner, and in the unlocking position, it is disengaged from the other locking partner. Preferably, the locking element serves to lock the door in at least one spatial direction, preferably in at least two spatial directions, and in particular, in all spatial directions. In particular, the locking element is pivotable between the unlocking position and the locking position by a pivot angle of more than 30 degrees, preferably more than 60 degrees, and in particular, more than 90 degrees.

[0012] The locking device has at least one or exactly one transmission element. In particular, the transmission element serves to transmit an actuating force from the actuating device to the locking element. The transmission element is displaceable along a longitudinal axis. In particular, the transmission element is positively guided along the longitudinal axis. The locking element is coupled to the actuating element via the transmission element, such that the locking element pivots between the locked and unlocked positions when the actuating element moves. In particular, the transmission element is pivotally connected to the transmission element on one side and to the locking element on the other. In particular, the transmission element is designed as a transmission rod, which preferably extends axially with respect to the longitudinal axis.For example, the transmission rod can be designed as a straight or an angled, in particular Z-shaped, transmission rod. Specifically, the transmission rod is connected to the actuating element at one axial end and to the locking element at another axial end.

[0013] The locking device comprises a guide housing which is designed and / or suitable for guiding the transmission element and the locking element axially with respect to the longitudinal axis. In particular, the transmission element and the locking element are guided linearly and / or in a straight line by the guide housing along the longitudinal axis. Preferably, the locking element is pivotably mounted in the guide housing. Preferably, the locking element and the transmission element are slidably mounted and / or guided in the guide housing with respect to the longitudinal axis. In particular, the guide housing has an insertion opening, wherein the transmission element is guided into the guide housing axially with respect to the longitudinal axis via the insertion opening. In particular, the guide housing has a locking opening, wherein the locking element is inserted through the locking opening.The locking element is pivotable into the guide housing. Preferably, in the unlocked position, it is fully pivoted into the guide housing, and in the locked position, it is pivoted out of the guide housing through the locking opening by the pivot angle. The guide housing can be made in one piece or in multiple pieces, particularly two pieces. Specifically, the guide housing is divided into two parts in the axial direction with respect to the pivot axis, so that the guide housing has two housing halves. For example, the two housing halves can be positively locked and / or force-locked and / or material-locked to each other in the axial direction with respect to the pivot axis.

[0014] Within the scope of the invention, it is proposed that the actuating element be rotatable about an axis of rotation. In particular, the actuating element and the transmission element are coupled to each other in such a way that a rotational movement of the actuating element is converted into a linear movement of the transmission element. Preferably, the actuating element is designed as a disk-shaped component which is arranged coaxially and / or concentrically to the axis of rotation. It should be noted that "disc-shaped" can also refer to, for example, round, elliptical, rectangular, or similarly geometric shapes of the component. In particular, the actuating element is rotatable about the axis of rotation within a limited range, especially between a first and a second end position.When the actuating element is rotated about the axis of rotation, the transmission element is moved along the axis of displacement to pivot the locking element between the locked and unlocked positions. Preferably, the locking element can be pivoted into the locked position when the transmission element is moved axially out of the guide housing, and into the unlocked position when the transmission element is moved axially in the opposite direction. In particular, the axis of rotation and the longitudinal axis are arranged perpendicular to each other.

[0015] The advantage of the invention lies particularly in the fact that the rotatable actuating element allows for a particularly compact connection of the locking device. Furthermore, the locking device, especially the transmission element, can be optionally connected to the actuating device in a horizontal, vertical, or diagonal orientation. Thus, a locking system is proposed that is characterized by a particularly flexible and customizable design. Moreover, the actuating device is characterized by a small installation space due to its compact connection.

[0016] In a further specification, it is provided that the locking element is moved into the locked position when the actuating element is rotated in one direction about the axis of rotation, and that the locking element is moved into the unlocked position when the actuating element is rotated in the opposite direction about the axis of rotation. In particular, when the actuating element is rotated in the direction of rotation, a thrust force is transmitted to the transmission element, and when the actuating element is rotated in the opposite direction, a tensile force is transmitted to the transmission element. Preferably, rotation of the actuating element in the direction of rotation is limited by the first end position, and rotation in the opposite direction is limited by the second end position.For example, the actuating device has an end stop for the actuating element, with the actuating element bearing against the end stop in the first end position in the direction of rotation and in the second end position in the opposite direction of rotation. The locking element is in the locked position in the first end position of the actuating element and in the unlocked position in the second end position. The fixed end stops ensure that the actuating element is not over-rotated, thus preventing damage to the locking device.

[0017] In a further embodiment, the actuating device comprises a rotatable drive element. In particular, the rotatable drive element can transmit a torque generated by hand force or an electric drive motor as a rotary motion to the actuating element. For this purpose, the rotatable drive element is connected to the actuating element coaxially with the axis of rotation, and the rotatable drive element applies an actuating force or torque directed about the axis of rotation to the actuating element, causing it to rotate. Preferably, the rotatable drive element is designed as a drive shaft, with the actuating element being non-rotatably connected to the drive shaft. When the actuating device is actuated, the actuating force is thus transmitted to the actuating element via the rotatable drive element, causing the actuating element to rotate about the axis of rotation.Thus, an operating device is proposed which is characterized by a particularly simple and cost-effective design.

[0018] In an alternative embodiment, the actuating device includes a movable drive element. In particular, the movable drive element can transmit a torque generated by manual force or an electric drive motor as a linear motion to the actuating element. For this purpose, the movable drive element is coupled to the actuating element, with the movable drive element applying an actuating force directed transversely to the axis of rotation to cause the actuating element to rotate. Preferably, the movable drive element is designed as a sliding bolt. Specifically, the actuating device has an axle section, with the actuating element rotatably mounted on the axle section.When the actuating device is activated, the actuating force is transmitted via the movable drive element to the actuating element, causing the actuating element to rotate around the axis of rotation. Thus, an actuating device is proposed which is characterized by a particularly compact design.

[0019] In a specific embodiment, the actuating element comprises at least one or exactly one cylinder section arranged eccentrically to the axis of rotation. When the actuating element is rotated, the cylinder section thus travels in a circular path around the axis of rotation. In particular, the cylinder section is designed as a cylindrical pin or cylinder bolt aligned axially with respect to the axis of rotation. The transmission element has a receiving section designed and / or suitable for receiving the cylinder section. Preferably, the cylinder section is positively engaged in the receiving section, at least in the axial direction with respect to the longitudinal axis. In particular, the receiving section is designed as an opening, for example, a through-hole or a bore, wherein the cylinder section is pushed through the opening and secured at its end by a locking device.For example, the locking device can be designed as a screw or clamping element. Thus, an actuating device is proposed which is characterized by a particularly simple and cost-effective connection of the locking mechanism.

[0020] In a further specification, the receiving section is designed as an elongated slot oriented transversely to the longitudinal axis, particularly in a transverse direction. The cylindrical section is slidably mounted within the receiving section to compensate for rotational movement. Specifically, the actuating element and the transmission element are movable relative to each other via the elongated slot during rotation. This relative movement compensates for any circular motion transmitted due to the rotation of the actuating element, ensuring that only linear motion along the longitudinal axis is transmitted to the transmission element.

[0021] In a further embodiment, the guide housing is provided with at least one or exactly one snap hook. In particular, the snap hook engages the guide housing axially with respect to the longitudinal axis. Preferably, the guide housing has exactly two snap hooks, which are arranged on the guide housing in the same direction relative to each other with respect to the longitudinal axis. The transmission element has at least one or exactly one snap hook receptacle. Preferably, the snap hook receptacle is designed as a recess arranged laterally on the transmission element, for example, a notch or a groove, into which the snap hook is positively engaged and / or receptacled. Preferably, the transmission element has at least one or exactly one snap hook receptacle for each snap hook.Preferably, the two snap hooks grip the transmission element on both sides, with the snap hook receptacles arranged laterally opposite each other on the transmission element.

[0022] According to this embodiment, the at least one snap hook can be engaged with the at least one snap hook receptacle in the locking position and / or the unlocking position of the locking element, thus securing the locking section against accidental release. Preferably, the transmission element has exactly one snap hook receptacle per snap hook, wherein the snap hook selectively snaps into the snap hook receptacle either in the locking position or in the unlocking position. Alternatively, the transmission element has exactly two snap hook receptacles per snap hook, wherein the snap hook snaps into one snap hook receptacle in the locking position and into the other snap hook receptacle in the unlocking position. Particularly preferably, the snap hook creates a releasable snap connection, which can be released automatically upon rotation of the actuating element.The snap connection thus proposes a locking system which is characterized by high functional reliability, whereby the snap connection prevents unwanted movement of the locking element due to, for example, vibrations.

[0023] In a further specific embodiment, the transmission element has a first guide section and the locking element a second guide section. In particular, the first and / or the second guide section is designed as a guide pin arranged on one or both sides. The guide housing has a first and a second guide receptacle, wherein the transmission element is guided in the first guide receptacle via the first guide section and the locking element is guided in the second guide receptacle via the second guide section. In particular, the first and / or the second guide receptacle is designed as a guide track arranged on one or both sides.Optionally, the first guide section of the transmission element is received in the guide receptacle with a small amount of play, particularly in the axial direction with respect to the axis of rotation, at least in the unlocked position. This allows the transmission element to be moved axially relative to the axis of rotation for assembly purposes. For this purpose, the guide receptacle can have a corresponding geometry in its rear area that allows the transmission element to tilt relative to the control housing in the unlocked position, thus facilitating the insertion of the cylinder section of the actuating element into the receiving section of the transmission element.

[0024] According to this embodiment, the first guide recess extends axially with respect to the longitudinal axis, and the second guide recess extends axially with respect to a further longitudinal axis. The longitudinal axis and the further longitudinal axis are arranged at an angle to each other. Preferably, the angle is greater than 15 degrees, preferably greater than 30 degrees, and in particular greater than 45 degrees. Preferably, the second guide recess thus has an upward slope compared to the first guide recess. When the transmission element is displaced, the locking element is therefore displaced along the further longitudinal axis and simultaneously pivoted about the pivot axis.

[0025] According to the invention, the locking element is pivotably connected to the transmission element via a first joint. In particular, the transmission element and the locking element are connected to each other via a joint pin to form the first joint. Preferably, the first joint is designed as a pivot joint with at least or exactly one, and in particular exactly two, degrees of freedom. For this purpose, the transmission element preferably has a connection section at its end, which has an elongated connection opening for receiving and / or guiding the joint pin. The locking element is pivotably connected to the guide housing via a second joint. Preferably, the second joint is designed as a further pivot joint with at least or exactly two degrees of freedom. The first joint is displaceable along the longitudinal axis, and the second joint is displaceable along the other longitudinal axis.In particular, when the transmission element is displaced along the longitudinal axis, the first joint is displaced along the longitudinal axis and the second joint is displaced along the second longitudinal axis, with the locking element simultaneously pivoting about the first and second joints in the guide housing.

[0026] In a further specification, the first joint is designed as an elongated slot joint. Specifically, the connecting opening for this joint is designed as a further elongated slot extending axially with respect to the longitudinal axis. Preferably, the joint pin is arranged to be displaceable axially with respect to the longitudinal axis within the connecting opening. Upon reaching the locking position, the transmission element can be moved axially with respect to the locking element from a transmission position to a locking position. In particular, the locking element can be pivoted relative to the transmission element between the locking position and the unlocking position in the transmission position.In particular, the locking element is locked in the locked position, preventing it from pivoting into the unlocked position via the transmission element, especially the connecting section. This secures the locking device against accidental release. Specifically, the transmission element remains in the transmission position during axial displacement along the longitudinal axis until the locking element reaches its locked position. Further axial displacement moves the transmission element from the transmission position, via the additional elongated hole, into the locked position relative to the locking section. To release the locking element, the transmission element is moved back from the locked position to the transmission position in the opposite axial direction.Particularly preferably, in the locking position of the transmission element, it is prevented that the locking element can be moved from the locking position to the unlocking position from the outside, in particular by external influence.

[0027] It is preferred that the second joint is formed between the second guide section and the second guide receptacle. Preferably, the second guide section is rotatably mounted in the second guide receptacle. Preferably, the second guide section, in particular the guide pin(s), has a cylindrical shape, allowing relative rotation between the second guide section and the second guide receptacle. Thus, a locking device is proposed which is characterized by a particularly compact design.

[0028] In a further embodiment, the locking device comprises an additional locking element, an additional transmission element, and an additional guide housing. In particular, at least the two locking elements and / or the two guide housings and / or the two transmission elements are structurally identical. The additional locking element is motionally coupled to the actuating element via the additional transmission element. Preferably, both transmission elements are jointly connected to the actuating element. For this purpose, the actuating element has an additional cylinder section, arranged eccentrically to the axis of rotation, for connecting the additional transmission element, which is positioned diametrically opposite to the cylinder section.When the actuating element is rotated, the other transmission element is displaced along the longitudinal axis in the opposite direction to the direction of the first transmission element, so that the two transmission elements move in opposite directions to pivot the respective locking element. Preferably, the two guide housings are arranged coaxially with respect to the longitudinal axis, and the two transmission elements are designed such that they are arranged coaxially with respect to the longitudinal axis and can be connected to the actuating element offset from each other.

[0029] A further aspect of the invention relates to a door arrangement according to claim 12, comprising at least or exactly one door, at least or exactly one locking partner, and the locking system as previously described, wherein the locking system is configured and / or suitable for locking the door to the locking partner. The locking partner is configured as another door or a door frame. Preferably, the door and / or the other door is configured as a sliding door. For example, the door arrangement can be configured and / or suitable for a cabinet, such as a control cabinet or tool cabinet.

[0030] In a further embodiment, the door is provided with a profile section. In particular, the profile section forms a door rebate or a door jamb. Preferably, the door is designed as a sheet metal door, with the profile section serving to reinforce the sheet metal door. The profile section has a hollow profile extending axially with respect to the longitudinal axis. Preferably, the hollow profile is designed as a square profile. For example, the profile section can be formed by forming, for instance, by repeatedly folding over an edge. The locking device, in particular the guide housing, is at least partially integrated into the hollow profile. In particular, the guide housing, the locking element, and the transmission element can be supplied as a pre-assembled unit.The additional guide housing, the additional locking element, and the additional transmission element are mounted or pre-assembled into the profile section as a further pre-assembled unit. The actuating device can be integrated into the door, particularly the door leaf, from the outside and connected to the two pre-assembled units. Thus, a locking system is proposed that can be easily integrated into the door and / or retrofitted.

[0031] In a further specification, it is provided that the guide housing is positively locked in the hollow profile, at least in the axial direction with respect to the longitudinal axis. In particular, the guide housing can be held securely in the profile section by means of a snap-fit ​​connection. For example, the guide housing can have a snap-fit ​​lug and the profile section a snap-fit ​​opening into which the snap-fit ​​lug engages to form the snap-fit ​​connection. For this purpose, the guide housing can preferably be inserted into the hollow profile in the axial direction with respect to the longitudinal axis. Similarly, the second guide housing can be arranged in the second profile section. Alternatively or optionally, the guide housing can be secured in the profile section by means of a screw connection, wherein at least one screw can be inserted laterally into the guide housing via a screw opening provided in the profile section and / or is screwed in.Optionally, the guide housing can have an insertion contour at its end, particularly on an axial end face with respect to the longitudinal axis, to form an insertion aid when the guide housing is inserted into the hollow profile. For example, the insertion contour is formed by a rounded or chamfered edge of the guide housing. Optionally, the guide housing can have a stop contour to form a depth stop in the axial direction with respect to the longitudinal axis when the guide housing is inserted into the hollow profile. For example, the stop contour is formed as a ridge, nose, serration, or the like molded onto the guide housing. Thus, a locking device is proposed which is characterized by particularly simple and quick assembly.

[0032] In a further embodiment, the locking element is provided with a hook section. Preferably, the hook section is formed by at least one angled hook, which projects, for example, more than 70 degrees, preferably more than 90 degrees, and in particular more than 110 degrees from the locking element. In particular, the hook section has two hooks and / or is interrupted and / or slotted. The profile section has a through-hole in the area of ​​the locking element. Preferably, the through-hole is formed as a perforation or bore. The locking partner has a receiving opening, wherein the hook section, in particular at least one of the hooks, is engaged in the receiving opening via the through-hole in the locking position.Preferably, the receiving opening, the passage of the profile section, and the locking opening of the guide housing are arranged congruently and / or overlapping with one another. Particularly preferably, the hook section engages in the receiving opening in such a way that the door is secured against displacement and prying. For this purpose, the hook section is preferably arranged in a form-fitting manner, particularly in one opening direction of the door and in a transverse direction perpendicular to the opening direction, within the receiving opening, with the hook section additionally engaging behind the locking partner. Thus, a locking device is proposed which is characterized by a particularly robust and secure locking action.

[0033] Further features, advantages, and effects of the invention will become apparent from the following description of preferred embodiments of the invention. These include: Figure 1a, b perspective views of a door arrangement as an embodiment of the invention; Figure 2 an exploded view of a locking system for the door arrangement from the Figure 1a , b Figure 3a, b perspective views of an actuating device of the locking system made of Figure 2 in two alternative versions; Figure 4a, different detailed views of the locking system of the Figure 2 Figures 5a, b, c each show a detailed view of the locking system in different locking states; Figure 6 shows a detailed representation of the door arrangement of the Figure 1b Figure 7: a perspective detail view of a transmission element of the locking system; Figure 8a, b: a sectional view of the transmission element of the Figure 7 .

[0034] Corresponding or identical parts are each provided with the same reference symbols in the figures.

[0035] The Figures 1a, bEach figure shows a perspective view of a door arrangement 1 with a locking system 2 as an embodiment of the invention. The figure is shown in the Figure 1a the door arrangement 1 in a front view and in the Figure 1b shown in a rear view. For example, the door arrangement 1 can form part of a cabinet, not shown, with the door arrangement 1 serving to open and close the cabinet.

[0036] The door assembly 1 comprises a door 3 and a locking partner 4, wherein the door 3 can be locked to the locking partner 4 via the locking system 2. The locking system 2 is integrated into the door 3, and in a locked state, the locking system 2 locks the door 3 to the locking partner 4. The door 3 is, for example, designed as a sliding door, which can be moved in one opening direction OR to open or close the cabinet. For example, the cabinet is designed as a sheet metal cabinet 1, wherein the door 3 is designed as a sheet metal door. The locking partner 4 can, for example, be designed as another door or a door frame.

[0037] The locking system 2 comprises an actuating device 5 and a locking device 6, wherein the actuating device 5 is operatively connected to the locking device 6. For example, the actuating device 5 is designed as an electrical or mechanical actuating device which, when actuated, switches the locking device 6 to the locked state. For example, the locking device 6 is designed as a mechanical sliding lock.

[0038] The actuating device 5 is integrated into the door 3, with the actuating device 5 being accessible from a front, as shown in Figure 1a shown, which can be actuated at an actuation point 7. For example, the actuation point 7 can be a keyhole, a combination lock, or an RFID interface. On the back of the door assembly 1, as shown in Figure 1bAs shown, the actuating device 5 is connected to the locking device 6, whereby when the actuating device 5 is actuated at the actuating point 7, the locking device 6 locks at two spaced-apart locking points 8a, b. In the locked state, the door 3 is thus locked to the locking partner 4 at the two locking points 8a, b, so that opening of the door 3 is prevented.

[0039] The door 3 has a profile section 9 which extends along an outer edge of the door 3. The profile section 9 has a hollow profile 10, in particular a square profile, wherein the locking device 6 is partially integrated into the profile section 9 or arranged in the hollow profile 10. For this purpose, the profile section 9 is interrupted in the area of ​​the actuating device 5, wherein a first assembly of the locking device 6 is mounted or partially integrated into an upper subsection 9a and a second assembly of the locking device 6 is mounted into a lower subsection 9b of the profile section 9.

[0040] The Figure 2 Figure 2 shows the locking system 2 in an exploded view. The actuating device 5 has an actuating element 11, wherein the actuating element 11 serves as a connection interface for the locking device 6 and is rotatably mounted on the actuating device 6 about a rotational axis D.

[0041] The locking device 6 comprises a first and a second locking element 12a, b, a first and a second guide housing 13a, b, and a first and a second transmission element 14a, b. The first locking element 12a, the first guide housing 13a, and the first transmission element 14a form the first assembly, and the second locking element 12b, the second guide housing 13b, and the second transmission element 14b form the second assembly of the locking device 6. The first locking element 12a is pivotally connected to the actuating element 11 via the first transmission element 14a, and the second locking element 12b is pivotally connected to the actuating element 11 via the second transmission element 14b.The actuating element 11 is designed as a disc-shaped component which has a cylinder section 11a, b arranged eccentrically to the axis of rotation D for connecting the two transmission elements 14a, b, wherein the two cylinder sections 11a, b are arranged diametrically opposite each other.

[0042] The two transmission elements 14a, b are each designed as a transmission rod and each has a receiving section 15a, b at one axial end face, which serves to receive the respective associated cylindrical section 11a, b. The two receiving sections 15a, b are each designed as an opening, wherein the respective cylindrical section 11a, b is rotatably received in the opening. At the other axial end face, the two transmission elements 14a, b are each connected to the associated locking element 12a, b to form a first joint G1, as shown in the Figures 5a to 5cThe locking element 12a, b is pivotably connected. For this purpose, the respective locking element 12a, b is pivotally connected to the corresponding transmission element 14a, b via a pivot bolt 16a, b.

[0043] The two guide housings 13a, b serve to guide the respective locking element 12a, b and the respective transmission element 13a, b. The two guide housings 13a, b are arranged coaxially opposite each other with respect to a longitudinal axis L1 and are in an assembly state as shown in Figure 1b The first guide housing 13a is shown mounted in the profile section 9. The first guide housing 13a can be inserted axially into the upper section 9a of the profile section 9, and the second guide housing 13b into the lower section 9b of the profile section 9, with respect to the longitudinal axis L1. For example, the longitudinal axis L1 is defined by a central axis of the hollow profile 10.

[0044] The Figures 3a, b Each figure shows a perspective view of two different versions of the operating device 5. Figure 3a The actuating device 5 has a displaceable drive element 17, which is displaceable along a displacement axis V. Furthermore, the actuating device 5 has an axle section 18, which extends coaxially to the axis of rotation D and serves to rotatably receive the actuating element 11. The actuating element 11 is rotatably mounted on the axle section 18 and secured against loss in the axial direction with respect to the axis of rotation D.

[0045] The movable drive element 17 is designed as a sliding bolt, with the actuating element 11 engaging with the movable drive element 17 such that when the movable drive element 17 is moved along the axis of movement V, the actuating element 11 rotates about the axis of rotation D. For this purpose, the actuating element 11 is selectively subjected to an actuating force F directed either in an axial direction or in the opposite axial direction with respect to the axis of movement V via the movable drive element 17. For example, the movable drive element 17 can be driven by an electric drive motor or by manual force.

[0046] In Figure 3bThe actuating device 5 has a rotatable drive element 19 which is rotatable about the axis of rotation D. The rotatable drive element 19 is designed as a drive shaft, with the actuating element 11 being rotationally fixed to the rotatable drive element 19, such that when the rotatable drive element 19 rotates about the axis of rotation D, the actuating element 11 is also rotated about the axis of rotation D. For this purpose, the actuating element 11 is selectively subjected to an actuating force F, in particular a torque, directed in one direction of rotation or in the opposite direction of rotation, via the rotatable drive element 19. For example, the rotatable drive element 19 can be driven by an electric drive motor or by hand force.

[0047] The Figure 4aFigure 1 shows a detailed view of the connection interface of the locking system 2. The receiving sections 15a, b are each designed as an elongated hole extending axially with respect to the displacement axis V. The cylinder sections 11a, b are thus received axially with respect to the displacement axis V in the receiving sections 15a, b with clearance. When the actuating element 11 is rotated, relative movement between the actuating element 11 and the two transmission elements 14a, b is therefore permitted. This relative movement prevents a rotational movement caused by the rotation from being transmitted to the two transmission elements 14a, b. This ensures that the two transmission elements 14a, b move exclusively in the axial direction with respect to the longitudinal axis L.

[0048] In addition, the two transmission elements 14a, b are fixed axially with respect to the axis of rotation D to the actuating element 11 by a locking device 20a, b each. For example, the locking devices 20a, b can be designed as clamping discs.

[0049] The Figure 4b Figure 6 shows a detailed view of the locking device, in particular the first assembly. It should be noted that the described design applies analogously to both sides, i.e., also to the second assembly.

[0050] The guide housing 13a has a locking opening 21, wherein the locking element 12a can be pivoted out of the guide housing 13a into a locking position VS and into the guide housing 13a into an unlocking position ES via the locking opening 21. The locking element 12a and the transmission element 14a are movably mounted and guided in the guide housing 13a for this purpose.

[0051] To guide the transmission element 14a, the transmission element 14a has a first guide section 22a and the guide housing 13a has a first guide receptacle 23a, wherein the first guide section 22a is guided and received in the first guide receptacle 23a. To guide the locking element 12a, the locking element 12a has a second guide section 22b and the guide housing 13a has a second guide receptacle 23b, wherein the second guide section 22b is guided and received in the second guide receptacle 23b. The two guide sections 22a, b are each formed by a guide contour molded onto both sides, which extends transversely to the longitudinal axis L1. The two guide receptacles 23a, b are each formed by a guide cam molded onto both sides. To form a second joint G2, the locking element 12a is rotatably received in the guide receptacle 23b via the second guide section 22b.For this purpose, the guide section 22b is formed, for example, by a cylindrical guide bolt.

[0052] The guide housing 13a has a snap hook 24 on each side, the two snap hooks 24 extending axially with respect to the longitudinal axis L1 and being elastically deformable transversely to the longitudinal axis L1. Correspondingly, the transmission element 14a has a snap hook receptacle 25 on each side, the snap hooks 24 engaging in their respective snap hook receptacles 25, for example, in the unlocked position ES of the locking element 12a, forming a releasable snap connection. The locking element 12a is thus secured against unintentional release by the snap connection in the unlocked position ES, and the snap connection can be released by actuating the actuating device 5.

[0053] The guide housing 13a has a locking contour 26a on its front side, which forms a locking connection with the profile section 9, as shown in Figure 1b The detent contour 26a is designed as a detent lug integrally formed with the guide housing 13a. Furthermore, the guide housing 13a has a stop contour 36 on its front face, which forms a depth stop when the guide housing 13a is inserted into the profile section 9. For example, the stop contour 36 is designed as a rib integrally formed with the guide housing 13a. Additionally, the guide housing 13a has an insertion contour 37 on an axial end face with respect to the longitudinal axis L1, which serves to form an insertion aid when the guide housing 13a is inserted into the profile section 9. The insertion contour 37 is designed as an inclined surface attached to the guide housing 13a.

[0054] Furthermore, the locking element 12a has a hook section 27, which is arranged at an angle, in particular at a 90° angle, on the locking element 12a. The hook section 27 is formed by two spaced-apart hooks 27a, b, one of which engages the locking partner 4 at the locking point 8a, as shown in Figure 1a , shown to be able to engage and the other of the two hooks 27b defines an end stop for the locking partner 4 in the opening direction R1.

[0055] The guide housing 13a has a screw receptacle 28 on both sides, which serves to receive a screw (not shown). The guide housing 13a can be additionally secured in the profile section 9 by screwing in the screw receptacle 28.

[0056] The Figures 5a, b, cEach figure shows a detailed side view of the locking device 6 in different locking states. The locking element 12a is shown in Figure 5a at the locking point VS, in Figure 5b in an intermediate position and in Figure 5c shown in the unlocked position ES. As can be seen from the Figures 5a, b, c As can be seen, the first guide receptacle 23a extends axially with respect to the longitudinal axis L1 and the second guide receptacle 23b extends axially with respect to a further longitudinal axis L2, wherein the longitudinal axis L1 and the further longitudinal axis L2 are arranged at an angle A to each other. For example, the angle A is approximately 45°.

[0057] In the locked position VS, the hook section 27 is completely removed from the guide housing 13a, and in the unlocked position ES, it is completely pivoted into the guide housing 13a. For this purpose, the transmission element 14a is displaced axially with respect to the longitudinal axis L1, while the locking element 12a is simultaneously displaced axially with respect to the further longitudinal axis L2. Due to the rising profile of the second guide receptacle 23b, the locking element 12a is pivoted simultaneously about the first and second joints G1, G2, or about a pivot axis S. The pivot axis S is preferably defined by the pivot pin 16a, as shown in Figure 2 represented, defined.

[0058] Figure 6Figure 1 shows a perspective view detailing the upper locking point 8a of the door assembly 1. The guide housing 13a is inserted axially with respect to the longitudinal axis L1 into the upper subsection 9a of the profile section 9 and is held in a form-fitting manner by the detent contour 26a. For this purpose, the profile section 9 has a corresponding detent receptacle 26b, in which the detent contour 26a is engaged. Optionally, the profile section 9 has a screw opening 29, which is congruent with the screw receptacle 28 of the guide housing 13a, so that the guide housing 13a can be additionally secured in the profile section 9 by means of the screw.

[0059] The profile section 9 has a through-hole 30 in the area of ​​the locking opening 21, the through-hole 30 being arranged overlapping or congruent with the locking opening 21. For example, the through-hole 30 is designed as a rectangular opening. The locking partner 4 has a receiving opening (not shown), the engagement section 27 being engaged in the receiving opening via the through-hole 30 in the locking position VS. The engagement section 21 ensures that the door 3 is secured against opening or prying open both in the opening direction R1 and in a direction R2 perpendicular to the opening direction R1.For this purpose, the hook section 27 engages the locking partner 4 in the locking position VS in the axial direction with respect to the longitudinal axis L1, so that the hook section 21 and the locking partner 4 are positively engaged with each other in both the opening direction R1 and the direction R2. This ensures a secure locking function and improved handling by the locking device 6.

[0060] Figure 7Figure 1 shows a perspective view of an axial end of the transmission element 14a, as previously described. The transmission element 14a has a connection section 31, which includes a connection opening 32 for receiving the pivot pin 16a. The receiving opening 32 is designed as a further elongated hole extending axially with respect to the longitudinal axis L1. The pivot pin 16a is axially displaceable within the receiving opening 32 with respect to the longitudinal axis L1. The first joint G1 is thus designed as an elongated slot joint, whereby the transmission element 14a is displaceable via the first joint G1 between a transmission position US and a locking position SS relative to the pivot pin 16a, in particular the associated locking element 12a (not shown here).

[0061] The connecting section 31 has a radius 33, over which the locking element 12a can pivot about the pivot axis S in the transmission position US of the transmission element 14a. A locking surface 34 adjoins the radius 33 on one side, whereby the locking element 12a is locked against pivoting about the pivot axis S by the locking surface 34 in the locking position SS of the transmission element 14a. An axial end face 35 adjoins the radius 33 with respect to the longitudinal axis L1 on the other side. For example, the axial end face 35 is defined by a radial plane of the longitudinal axis L1.In particular, the end face 35 and the radius 33 form a force transmission contour, whereby when the transmission element 14a is displaced in an axial direction AR along the longitudinal axis L1, a shear force is transmitted via the force transmission contour to the locking element 12a in order to pivot the locking element 12a into the locking position VS. For example, during pivoting about the pivot axis S, the locking element 12a rests against the force transmission contour, so that the shear force is introduced into the locking element 12a via the force transmission contour. For example, during pivoting from the unlocked position ES to the locking position VS, the locking element 12a slides off the force transmission contour.

[0062] The Figures 8a, b Figures 14a and 12a each show a sectional view of the transmission element and the locking element, respectively. Figure 8aThe transmission element 14a is in the transmission position US and in the Figure 8b in the locking position SS. In the transmission position US, the pivot pin 16a is located in the upper part of the connection opening 32, so that the locking element 12a can pivot freely around the pivot axis S over the radius 33 between the unlocking position ES and the locking position VS. This is achieved in particular by a displacement of the transmission element 14a in the axial direction AR with respect to the longitudinal axis L1, as already described in the Figures 5a to 5c was described.

[0063] When the locking element 12a reaches the locking position VS, as in Figure 8bAs shown, the transmission element 14a can be moved from the transmission position US to the locking position SS by a further axial displacement AR relative to the locking element 12a. In the locking position SS, the pivot pin 16a is located in the lower part of the connection opening 32, and the locking element 12a is prevented from pivoting from the locking position VS to the unlocking position ES by the locking surface 34. This prevents the locking element 12a from unintentionally releasing in the locking position VS, thus providing a particularly secure locking mechanism.

[0064] For release, the transmission element 14a is first moved back into the transmission position US in a direction GR opposite to the axial direction AR relative to the locking element 12a, so that the locking element 12a is released over the radius 33 and can pivot again around the pivot axis S.
