Description

[0001] The present invention relates to a sliding door according to the preamble of claim 1.

[0002] Sliding doors of the generic type and also of the inventive type are provided with a frame that can be aligned in a vertical position and a sliding sash that is guided horizontally slidably in the frame relative to the frame thus aligned.

[0003] The sliding panels of such sliding doors can also be designed as lift-and-slide panels if they are vertically height-adjustable relative to the frame and are also horizontally movable. They are generally fitted with multiple panes of glass and preferably have a surrounding frame. Such sliding panels can be designed so that at least the lower frame profile can be recessed into the floor, at least in one closed position. In this way, they allow for a virtually frameless appearance at the floor.

[0004] DE102020115506A1, DE102018130394A1, DE102021106832A1 and DE102020111621A1 reveal sliding doors.

[0005] Based on this state of the art, a sliding door and a locking device are to be created with which sliding leaves of sliding doors can be securely locked to the frame in a desired position - especially in a closed position.

[0006] The purpose of the invention is to solve this problem.

[0007] The invention solves this problem through the subject matter of claim 1. According to this claim, a sliding door with at least one lockable sliding leaf is created, which has at least the following: a vertically alignable frame which, in the vertical orientation, has at least two vertical and at least one upper and one lower horizontally oriented frame members; a sliding sash which is slidably guided in the frame, wherein the sliding sash is slidably guided horizontally in the frame in the vertical orientation; wherein the sliding sash has a sash frame which is formed from at least one lower horizontal sash frame profile, two vertical sash frame profiles, and one lower horizontal sash frame profile; wherein a basic element of a locking device is inserted in the upper horizontally oriented frame member of the frame, the locking device (500) being substantially or entirely housed in the rebate between the frame and the sash frame; wherein the locking device has a locking arm.which is pivotably mounted on the base element about a horizontal axis of rotation A, which is aligned parallel to the sliding direction, and which can be moved from an unlocked position to a locked position by means of a pivoting movement by an electromechanical actuator, and wherein the locking arm in its locking position has an angle α to the vertical which is greater than 0°.

[0008] This creates a sliding door with a sliding sash that can be easily and securely locked, and is very well protected against unauthorized opening.

[0009] On the one hand, electromechanical actuation is practical and safe. In this configuration, the locking arm, when locked, has an angle α to the vertical greater than 0°. This prevents forced unlocking of the sliding sash—e.g., with a screwdriver, rod, or similar tool—more effectively than with a vertically oriented locking arm, since the locking arm must first be moved through its maximum vertical extension. This is prevented by an upper horizontal sash frame profile, as it obstructs the pivoting locking arm. Preferably, a surface element can be integrated into the sash frame. The actuator's electric motor is preferably designed to be controllable.

[0010] The angle α can preferably be between 5° and 25°. This creates a particularly robust locking mechanism for the bolt arm against forced unlocking.

[0011] It is preferred if the locking device further comprises a locking piece as a buttress, wherein the locking piece is fixed to the upper horizontal wing frame profile of the sliding wing.

[0012] It is further provided that the locking arm is pivotable about a horizontal axis of rotation A, which is aligned parallel to the sliding direction. This is particularly advantageous if the sliding sash is a lift-and-slide sash and the locking arm can be moved from the unlocked position, in which the locking arm lies in a horizontal plane, into the locked position by a downward pivoting motion, preferably with an outer surface of the locking arm being inclined at an angle α to the vertical direction. In this way, a sliding door that is easy to lock and is particularly well secured against break-in attempts is created.

[0013] It is further preferred if, during its pivoting movement from the unlocked position to the locked position, the locking arm engages in a gap-like free space or installation space BR, which enlarges or extends in the rebate space between the sliding sash and the upper cross member of the frame when the sliding sash, which is a lift-and-slide sash, has assumed its lowered position. In this way, the locking device is particularly well suited for use with lift-and-slide doors.

[0014] According to a particularly preferred embodiment of the invention, the locking device comprises a locking bolt, the locking bolt being fixed to the upper horizontal sash frame profile of the sliding sash. This results in a structurally simple and easy-to-install locking bolt, for which no special installation space is advantageously required. The height of the locking bolt is preferably selected such that, even in the lowered position, it forms a support for the locking arm, thus securing the sliding sash against being pushed open even when the locking arm is extended and the sash is lowered.

[0015] According to a further preferred embodiment of the invention, the locking arm can engage in front of the locking element in the locking position, thus blocking any sliding movement of the sliding sash from the closed position. This results in a robust locking mechanism for the sliding sash that is both structurally simple and readily implementable in manufacturing.

[0016] In a further particularly preferred embodiment of the invention, the locking arm can also be pivotably mounted on a first leg of the base element. This results in a simple and robust kinematic mechanism for the locking and unlocking function of the locking device.

[0017] Furthermore, according to another particularly preferred embodiment of the invention, the locking arm, in its unlocked position, engages in a recess provided in a second leg of the base element, so that the locking arm can be moved past the locking piece when the sliding element is moved. This results in an advantageous, space-saving arrangement of the locking arm in the unlocked position.

[0018] In a further particularly preferred embodiment of the invention, the actuator is an electric motor. This results in an advantageously simple actuator to regulate or control, requiring minimal installation space.

[0019] Furthermore, in another particularly preferred embodiment of the invention, the actuator can be controlled via pulse width modulation. This results in simple control of the actuator.

[0020] In a further particularly preferred embodiment of the invention, the actuator can also act on a gearbox, the gearbox preferably being arranged coaxially to a shaft of the actuator. This results in a space-saving torque transmission for the actuator.

[0021] According to a further preferred embodiment of the invention, a crank of a linkage mechanism can be fixed to an output shaft of the transmission in a rotationally fixed manner, and the crank of the linkage mechanism is coaxially mounted on the output shaft of the transmission with a first eye. This provides a space-saving kinematic system that generates a reciprocating motion from a rotary motion of the transmission.

[0022] According to a further particularly preferred embodiment of the invention, the locking arm is held in its end positions by a slight self-locking mechanism of the gearbox, so that in the event of a malfunction, the locking arm can be manually unlocked with a special tool if necessary. This results in a structurally simple and, in the event of a malfunction, easy-to-use emergency opening mechanism for the sliding sash.

[0023] It is also advantageous if the unlocked and locked positions of the locking arm can be detected and evaluated by limit switches controlled by the locking device. This allows the locking status of a sliding sash to be determined at any time, independent of a higher-level control system.

[0024] Furthermore, according to another particularly preferred embodiment of the invention, at least one limit switch can be mounted in the locking arm and a magnet can be attached to the locking piece for end position detection. This allows for a simple and independent closing and opening monitoring of the sliding sash, separate from the control unit of the sliding sash.

[0025] According to a further preferred embodiment of the invention, the locking device may have an input line and an output line. This allows the locking devices of further sliding leaves to be connected in series simply and advantageously.

[0026] It is also preferred that the control of the locking device is operatively connected to the wing control unit (not shown here) of the sliding wing 1.

[0027] Further advantages, features, and details of the invention will become apparent from the following description, in which several embodiments of the invention are explained in more detail with reference to the accompanying figures. The invention is not limited to these embodiments but also includes embodiments not shown in the figures but falling under the claims.

[0028] The position and orientation terms used below, such as "on," "vertical," "horizontal," "right," and "left," refer, without further explanation, to the drawing plane of the respective figure. A coordinate system is provided within each figure for better orientation. This coordinate system is uniform for all figures, so it rotates with the orientation of the respective figure.

[0029] Fig. 1a shows a sliding door that can be inserted into a wall opening or in Fig. 1 The invention also features an inserted, set frame 300. A sash is slidably guided in the frame 1. The frame is here exemplified as a lift-and-slide sash 1. The invention is described by way of example using this lift-and-slide sash 1, but it can also be used with a sliding sash 1 without a lifting function.

[0030] The 300 frame is according to Fig. 1 vertically or parallel to an xy-plane according to the coordinate system in the Figuren 1a bis 1 e aligned. The sliding sash 1 is guided slidably in the frame 300. This is in Fig. 1a shown in a closed position, in which the sliding sash 1 closes a passage D through the frame 300. In addition to the sliding sash 1 shown, - as in the Figuren 1a bis 1e As shown, a fixed glazing element 2 is provided. However, one or more additional sliding sashes 1 may also be arranged in the frame or in the wall opening (not shown).

[0031] Adjoining the wall opening at the bottom of the frame 300 is a horizontal guide channel 3, which extends below a floor level designated here as "OKFF" ("top edge of finished floor"). The sliding sash 1 can be lowered into a position as described in Fig. 1a shown, can be lowered into the guide channel 3, for example in such a way that in the lowered position a lower frame profile (not shown here, see Fig. 3 ) of the sliding wing 1 is not visible.

[0032] The sliding sash 1 can also be displaceable relative to and on a first, height-adjustable roller element 50. For this purpose, it can have a rail-like running surface on its underside.

[0033] The sliding wing 1 can be moved by changing the height level of the first roller element 50, which is located in Fig. 1b , Fig. 1c und Fig. 1d As shown, and briefly described by way of example, the sliding sash 1 can be moved from the guide channel 3 – i.e., from a lowered position – into a travel position at the finished floor level (FFL). From the travel position, the sliding sash 1 can be moved out of the position shown in the diagram. Fig. 1a The depicted closed position is transformed into a displaced position that opens passage D here - as in Fig. 1d The process is shown. For this purpose, the guide channel 3 has a second roller element 60, which is aligned with the first roller element 50.

[0034] In Fig. 1c Figure 1 shows how the sliding sash 1, in its moving position, has left the closed position and moved towards the fixed glazing 2. Part of the sliding sash 1 is guided on the first roller element 50, and another part of the sliding sash 1 is guided on the second roller element 60, as shown in Figure 2. Fig. 1e shown - optionally also able to change its elevation.

[0035] In Fig. 1d The sliding wing 1 has reached the open position in its travel position. Fig. 1e The illustration shows that the sliding sash 1 can optionally be lowered into a lowered position when in the open position.

[0036] In Fig. 2 is a top view in section of the sliding wing 1 according to Fig. 1a oder Fig. 1b As shown, a frame 300 is inserted into the wall opening. This frame preferably has at least two vertical and two or more horizontally oriented frame mullions in a vertical orientation. Fig. 2 The two lateral vertical frame members 310, 320 are shown. A central vertical frame member 350 is also shown in section, which may belong to a fixed surface element, preferably to the fixed glazing 2.

[0037] Furthermore, a floor beam 330 – also called a threshold or clamp beam – is shown. This can, for example, be designed with its upper edge flush with the finished floor level (FFL) – in order to enable an advantageous barrier-free passage – and thus be completely accommodated by the guide channel 3.

[0038] The left vertical frame member 310 and the right vertical frame member 320 can each have two shells 311, 312 and 321, 322 respectively, which are connected to each other via insulating webs 313, 323. The shells 311, 312 and 321, 322 can be connected as shown in Fig. 2 The shells shown are made from geometrically identical profiles. This is advantageous but not mandatory. The shells 311, 312 and 321, 322 may have one or more hollow chambers. The insulating webs 313, 323 are preferably made of a plastic material. The shells 311, 312 and 321, 322 are preferably made of a light metal by an extrusion process. Alternatively, the shells 311, 312 and 321, 322 may also be made of a different material and / or by a different manufacturing process.

[0039] The lateral vertical frame members 310, 320 of the frame 300 thus formed each have an E-shaped cross-sectional geometry, which are arranged in a mirror image to each other in the executed frame 300. A first left rebate space 314 and a second left rebate space 315 as well as a first right rebate space 324 and a second right rebate space 325 can each be closed with a snap-in cover profile 316, 326.

[0040] In the example of the Fig. 2 In the fixed glazing area 2, the second right rebate 325 of the right vertical frame member 320 is closed with the cover profile 326, while in the sliding sash area 1, the first left rebate 314 of the left vertical frame member 310 is closed with the cover profile 316. The cover profile 316, 326 is preferably made of a light metal by an extrusion process. Alternatively, the cover profile 316, 326 can also be made of a different material and / or by a different manufacturing process.

[0041] The fixed glazing 2 is inserted into a frame 200. The rebate spaces 211, 221 of the frame 200 are sealed against the environment with elastic seals that conform to the fixed glazing 2.

[0042] The frame 200 of the fixed glazing 2 shows a left vertical frame profile 210 and a right vertical frame profile 220. The frame of the fixed glazing 2 may have additional frame profiles. For example, an upper and a lower frame profile (not shown here) are conceivable. The frame profiles 210 and 220 are preferably made of a plastic material by an extrusion process. Alternatively, the frame profiles 210 and 220 can also be made of a different material and / or by a different manufacturing process.

[0043] The fixed glazing 2 engages with its right vertical edging profile 220 of the edging frame 200 in the second right rebate space 325 of the right vertical frame mullion 320. The resulting gaps between the edging profile 220 and the rebate space 325 are each sealed with a sealing profile.

[0044] The fixed glazing 2 further engages with its left vertical edging profile 210 in a rebate space 351, which is formed by the centrally arranged vertical frame member 350. The centrally arranged vertical frame member 350, together with the cover profile 316, which closes the first left rebate space 314 in the area of ​​the left vertical frame member 310, defines the opening D.

[0045] A retaining profile 352 is inserted into the rebate 351 of the centrally arranged vertical frame member 350 and preferably firmly connected to the frame member 350. This firm connection can be achieved by a material bond, such as adhesive bonding. The left vertical retaining profile 210 of the frame 200 of the fixed glazing 2 is inserted into the retaining profile 352 and firmly connected to it via one or more positive locking connections. The resulting gaps are sealed by appropriate sealing profiles.

[0046] A surface element – ​​here designed as glazing – of the sliding sash 1 is inserted into a sash frame 100. The rebate spaces 111, 121 of the sash frame 100 are sealed against the environment with elastic seals that conform to the surface element.

[0047] Of the sash frame 100 of the surface element of the sliding sash 1, a left vertical sash frame profile 110 and a right vertical sash frame profile 120 are shown here. The sash frame of the glazing of the sliding sash 1 can have further sash frame profiles. For example, an upper horizontal sash frame profile 140 and a lower horizontal guide frame profile would be conceivable (neither shown here, see below). Fig. 3 The sash frame profiles 110, 120, 140, 150 are preferably manufactured from a plastic material by an extrusion process. Alternatively, the sash frame profiles 110, 120, 140, 150 can also be manufactured from a different material and / or by a different manufacturing process.

[0048] The surface element of the sliding sash 1 engages with its left vertical sash frame profile 110 in the second left rebate 315 of the left vertical frame mullion 310. The left vertical sash frame profile 110 may be fitted with a protective cap 111, which is snapped onto the sash frame profile 110. The resulting gaps between the sash frame profile 110 and the rebate 315 are each sealed with a sealing profile.

[0049] The surface element of the sliding sash 1 further engages with its right vertical sash frame profile 120 in a rebate space 131, which is formed by a finishing profile 130.

[0050] In A retaining profile 132 is inserted into the rebate 131 of the end profile 130 and preferably firmly connected to the end profile 130. This firm connection can be achieved by a material-bonded connection, such as gluing. The right vertical sash frame profile 120 of the sliding sash 1's surface element is inserted into the retaining profile 132 and firmly connected to it via one or more positive-locking connections. The resulting gaps are sealed by appropriate sealing profiles.

[0051] In Fig. 3 A side view of the sliding sash 1 is shown in section. The bottom rail 330 and an upper cross rail 340 of the frame 300 are shown here.

[0052] The upper cross member 340 can be similar to the left vertical frame member 310 (see Fig. 2 ) and the right vertical frame member 320 (see also Fig. 2 ) be constructed. This is advantageous, but not mandatory. In contrast to the vertical frame members 310, 320, the upper cross member 340 has at least one or - as in Fig. 3 shown - several guide surfaces 343, 344.

[0053] The guide surfaces 343, 344 are part of a guide bearing 40 of the sliding sash 1. It should be noted that the guide bearing 40 of the sliding sash 1 merely guides it along the guide surfaces 343, 344 when it is moved from the closed position to the open position, but does not bear any load, i.e., in particular, it does not absorb the weight of the sliding sash 1. Accordingly, the guide bearing 40 acts as a floating bearing with respect to the movement of the sliding sash 1.

[0054] The guide bearing 40 can have one or more guide carriages 41, on which at least one or more – here two – guide rollers 42, 43 are rotatably mounted. These rollers can roll on the guide surfaces 343, 344 and thereby guide the sliding sash 1 in its upper area during movement. The sliding sash 1 can thus also have a guide relative to the frame 300 in its upper area and, if necessary, a sliding drive.

[0055] For this purpose, the sliding sash 1 is connected to the guide carriage(s) 41 via a profile rail 44 and a bolt 45. The profile rail 44 can be positively connected to the upper horizontal sash frame profile 140 in a direction perpendicular to the direction of movement, thus creating a fixed connection when moving from the lowered position to the extended position.

[0056] A belt lock 46 can be integrated into the guide carriage 41, with which a belt (not shown here) of a wrap-around drive is secured to the guide carriage 41, so that the guide carriage 41 can be moved by the wrap-around drive. Preferably, the belt is a toothed belt and the actuator is an electric motor.

[0057] The surface element of the sliding sash 1 engages in a rebate of the upper horizontal sash frame profile 140 and is sealed against the environment by sealing profiles. Furthermore, the surface element of the sliding sash 1 is sealed to a rebate 345 of the second shell 342 of the upper horizontal frame mullion 340 by two brush seals 346, 347. This creates a flexible, robust, and effective seal with respect to vertical movement of the sliding sash 1, which occurs when the sliding sash 1 is raised from the lowered position to the sliding position and vice versa when lowered from the sliding position to the lowered position.

[0058] In the Fig. 4a, 4b and 4c The upper horizontal sash frame profile 140 of the lift-and-slide element 1 and the upper cross member 340 of the frame 300 are each shown in section. See also Fig. 6a .

[0059] A U-shaped base element 501 of a locking device 500 is inserted into the upper cross member 340 of the frame 300 – more precisely, in the area of ​​the guide surfaces 343, 344 of the upper cross member 340 – and is attached to the upper cross member 340 on the inner side facing the sliding sash. The locking device 500 has a U-shaped base element 501. The locking device 500 is designed to lock the sliding sash 1 to the frame 300 in a closed position, so that it can only be moved from the closed position to the open position after the lock has been released. This serves in particular to prevent unauthorized sliding of the sliding sash 1 into its open position.

[0060] The basic element 501 can have an actuator 502. This can be inserted into the basic element 501.

[0061] The actuator 502 is designed to move a locking arm 508 from an unlocked position (see Fig. 5b as well as Fig. 6c ) to move into a locking position and back out of it by a pivoting motion (see Fig. 6a und 6b ).

[0062] The actuator 502 can, for example, be configured to do this – as shown in Fig. 5c The actuator is designed to generate a rotational movement. Preferably, it comprises an electric motor. This electric motor can particularly preferably be electronically controlled by means of a control unit (not shown).

[0063] The actuator 502 acts on a gearbox 503. The gearbox 503 can be designed in various ways. It can then preferably be arranged coaxially to a shaft of the actuator 502. The gearbox 503 can be designed to transmit the torque of the actuator 502. A crank 504 of a linkage 523 can be fixed to an output shaft of the gearbox 503 in a rotationally fixed manner, as shown in Fig. 5d The crank 504 is shown here with one eye coaxially mounted on the output shaft of the gearbox 503. (see Fig. 5d ).

[0064] The crank 504 of the coupling mechanism 523 can have an eye 505 at its outer end. A link 506 can be rotatably connected to the crank 504, the link 506 in turn having, for example, an eye 507a, b on each side. The connection between the crank 504 and the link 506 can be made by a bolt that passes through the eye 505 of the crank 504 and the eye 507a of the link 506.

[0065] The handle 506 can be rotatably connected to the locking arm 508 of the locking device 500. The connection between the crank 504 and the handle 506 can be created by a bolt that passes through the eye 505 of the crank 504 and the eye 507a of the handle 506.

[0066] The locking arm 508 has a supported end 519 with which it is pivotably mounted on a first leg 509 of the base element 501 about a pivot axis A, as shown in Fig. 4a, 4b , 4c as in Fig. 5a , 5c , 5d, 5e and in Fig. 6a, 6b , 6c is shown.

[0067] The coupling mechanism 523 allows the locking arm 508 to be moved from the unlocked position, in which the locking arm 508 is preferably in a horizontal plane - i.e., with respect to the coordinate system in the Figuren 4a bis 4c in a plane parallel to the xz-plane - by means of a downward pivoting movement - i.e. in the negative y-direction with respect to the coordinate system in the Figuren 4a bis 4c - move into the locking position.

[0068] The pivot axis A preferably extends horizontally, parallel to the direction of movement of the sliding wing 1 or with respect to the coordinate system in Fig. 4a bis 4c in the direction of the x-axis.

[0069] The locking arm 508 has an L-shaped cross-sectional area, such that the locking arm 508 further comprises an inner surface 520, an outer surface 521 and a free end 522 (see also Fig. 5a bis 5d ). Due to the L-shaped cross-section of the locking arm 508, the locking arm 508 can, in its unlocked position, fold around the actuator 502 in a space-saving and protective manner, like a housing section (see Fig. 5b ).

[0070] With the aid of the gearbox 503 and the coupling gearbox 523, the actuator 502 can here move the locking arm 508 from the unlocked position, in which the locking arm 508 is preferably in a horizontal plane - i.e., with respect to the coordinate system in the Figuren 4a bis 4c in a plane parallel to the xz-plane - by means of a downward pivoting movement - i.e. in the negative y-direction with respect to the coordinate system in the Figuren 4a bis 4c - move into the locking position (see also Fig. 6a und 6b ).

[0071] The locking arm 508 pivots and, during its pivoting movement from the unlocked position to the locking position, preferably advantageously engages in a space BR extending between the sliding sash 1 and the upper cross member 340 of the frame 300 when the sliding sash 1 has assumed its lowered position (see [reference]). Fig. 4a bis 4c , as well as Fig. 6a und 6b ).

[0072] The locking arm 508 is therefore not located centrally above the glazing in its locking position, but rather in relation to the glazing in relation to a yz-plane according to the coordinate system in the Figuren 4a bis 4c more to the side, along a side edge.

[0073] The design chosen here is simple, safe, and compact. However, this functionality can also be achieved in other ways.

[0074] The end positions - i.e. the unlocked position and the locked position - of the locking arm 508 can preferably or optionally be detected and evaluated by limit switches of a control unit 510 of the locking device 500.

[0075] The locking arm 508 is particularly preferably not parallel to the plane of the surface element in its locking position - here as in a vertical plane or xy-plane according to the coordinate system in the Figuren 4a bis 4c The glazing is aligned – the sliding sash 1 is aligned. Rather, it has an angle α to the vertical or, in this case, also to the plane of the surface element, which is greater than 0° in the direction of the locking position of a locking bolt 511, see [reference]. Fig. 4a bis Fig. 4c Preferably, the angle α lies between 5° and 25°.

[0076] This prevents the sliding sash 1 from being forcibly unlocked – e.g., with a screwdriver, rod, or the like – more effectively than with a vertical orientation of the locking arm 508, since in the latter case the locking arm 508 must first be moved to its maximum vertical extent. However, this is prevented by the upper horizontal sash frame profile 140, as it obstructs the pivoting locking arm 508.

[0077] The vertex of angle α lies on the pivot axis A of the locking arm 508; a first leg of angle α forms a perpendicular vertical. The first leg is therefore parallel to the x-axis of the coordinate system in the Figuren 4a bis 4c An outer surface 521 of the locking arm 508 is aligned in the direction of the second leg of the angle α. This outer surface is preferably oriented towards the outside of the building when installed in a wall opening, so that attempts to break in are significantly hampered by the locking device.

[0078] The locking device 500 may also preferably have the locking piece 511 on the outside or top side of the sash frame facing the frame (see Fig. 4a bis Fig. 4c as well as Fig. 5a , 5c , 5d, 5e and Fig. 6a, 6b , 6c ).

[0079] The locking device 500 can therefore be located entirely or substantially in the rebate space between the frame and the sash frame.

[0080] The locking piece 511 can be slid into and fixed in the upper outer grooves of the upper horizontal sash frame profile 140 of the sliding sash 1. The height of the locking piece 511 is preferably selected such that, on the one hand, lifting / sliding movements are possible and, on the other hand, a support for the locking arm 508 can be formed even in the lowered position.

[0081] The locking arm 508, in its unlocked position, can engage in a recess 512 which is provided in a second leg 513 of the base element 501, so that the locking arm 508 can be moved past the locking piece 511 when the sliding element 1 is moved (see also Fig. 5c and Fig. 6c ).

[0082] Optionally, at least one limit switch 518 can be mounted on or in the locking arm 508. Additionally, a magnet 517 can then be attached in the locking piece 511 for independent end position detection (see Fig. 5c In another option, the locking piece 511 can also be provided with a stop 514 (see Fig. 5e ).

[0083] The sliding wing 1 can be equipped with an actuator (see Fig. 6a ) be equipped with a mechanism that allows it to be moved from the open position to the closed position in the travel position. If the actuator is actuated by a sash control unit (not shown here) with the aim of moving the sliding sash 1 into the closed position, the sliding sash 1 is first moved automatically to an end position of the closed position.

[0084] Once the sliding sash 1 is in the desired end position, the sash control unit (not shown here) sends the "Lock" command to the locking device 500. This command is evaluated by the control unit 510 of the locking device 500 (see Fig. 5a ). Then, preferably via pulse width modulation (PWM) of the actuator 502, the locking arm 508 is moved from the unlocking position to the locking position by a pivoting movement.

[0085] The control unit 510 of the locking device 500 is therefore in operative connection with the wing control unit (not shown here) of the sliding wing 1.

[0086] The locking arm 508 engages in the locking position in front of the locking piece 511 with respect to an opening movement of the sliding sash 1 and thus blocks a sliding movement of the sliding sash 1 (see also Fig. 5a as well as Fig. 6a und 6b ).

[0087] To move the sliding sash 1 from the closed position to the open position, the locking arm 508 is first moved from the locking position to the unlocked position - i.e. unlocked (see Fig. 5b and Fig. 6c ). Subsequently, the control unit 511 of the locking device 500 sends the information to the wing control unit that the sliding wing 1 can be moved.

[0088] The locking device 500 has an input line 515 and an output line 516 (see Fig. 5a This allows the control signals from the wing control unit to be looped through. Multiple 500 locking devices can therefore be connected in series.

[0089] The locking arm 508 is held in the end positions by a slight self-locking mechanism of the gearbox 503, so that in the event of a breakdown the locking arm 508 can be manually unlocked with a special tool if necessary.

[0090] The locking device 500 thus meets a high safety standard; furthermore, the locking device 500 provides a locking and opening monitoring independent of the operating system of the sliding wing 1. Bezugszeichenliste
