EP3334877B1 - Locking device for sliding wing - Google Patents

Description

TECHNICAL AREA

The present invention relates to a locking device for a sliding sash and a sliding sash system, in particular an automatic door system, with such a locking device.

STATE OF THE ART

The EP 2 607 580 teaches a locking device for a sliding door system for controlling access to a building opening. The door leaf of the sliding door is suspended from a carriage, the carriage together with the leaf being movable in a running profile arranged above the leaf to cover or clear the building opening. In order to lock the sash in a desired position in the running profile, the locking device, which is fixedly arranged with respect to the running profile, has a locking pin which can be moved between a locking position and an unlocking position and which interacts with a tab on the carriage to fix the carriage in the running profile.

The locking device and carriage are now further designed so that in said desired position the locking pin and the carriage-side engagement tab are aligned such that the locking pin engages in the tab by moving into the locking position and thus blocks the carriage in the running profile.

The actuating element for the locking pin is a lifting magnet with a magnetically movable armature, with a compression spring being provided to counteract the magnetic force for the purpose of resetting the armature or bolt.

Such an arrangement has the disadvantage that the force curve of the lifting magnet is strongly dependent on the position of the armature and that the curve of the force of the lifting magnet and the curve of the force of the compression spring are not optimally matched to one another.

The EP 2 784 255 A2 discloses a locking and locking unit for a partition wall system. For locking, a closure element attached to the partition is rotated in such a way that it engages in a receptacle which is arranged stationary with respect to a running rail.

DISCLOSURE OF THE INVENTION

It is an object of the present invention to overcome these disadvantages and to provide an improved locking device, in particular a carriage lock, for a sliding sash, in particular a sliding door.

• ein erstes Verrieglungselement, welches beweglich gelagert ist;
• eine Betätigungsvorrichtung zur Bewegung des ersten Verriegelungselements zwischen einer Entriegelungsposition und einer Verriegelungsposition;
• wobei die Betätigungsvorrichtung ein Rotationsantrieb ist,
• und wobei die Verriegelungsvorrichtung zwei oder mehr solche Rotationsantriebe umfasst.

This object is achieved by the locking device according to claim 1. Accordingly, a locking device, in particular a carriage lock, is proposed for at least one sliding sash, in particular a sliding door, for checking a building opening, the locking device being designed to lock at least one sliding sash, the locking device comprising:

• a first locking element which is movably supported;
• an actuating device for moving the first locking element between an unlocking position and a locking position;
• wherein the actuating device is a rotary drive,
• and wherein the locking device comprises two or more such rotary drives.

The locking element can be a locking element, a tab element or more generally a counter element, this counter element in positive engagement with an element on the carriage or on the sliding sash with respect to the Direction of movement can be brought. The locking element is preferably designed such that its movement between the unlocking position and the locking position is a pivoting or rotational movement.

In the context of the present invention, the expression " between the unlocking position and the locking position" includes both the movement against the unlocking position and the movement against the locking position, if off nothing else emerges from the context.

Alternatively, a construction can also be provided which enables this movement as a translation or displacement or as a combination of pivoting and displacement.

The present invention is based on the insight that a rotary drive can be used to actuate the locking device. The rotary drive can be optimally adapted to the application-specific necessary force curve via a gear. The known lifting magnet provides a relatively small lifting force when the armature is extended, which then increases as the armature is increasingly retracted. This stroke-dependent force profile is disadvantageous and which can be overcome with a rotary drive, in particular a gear motor, particularly preferably an electric motor, preferably with a downstream gear. It is also conceivable that the motor acts on the locking element via a cam in order to achieve a desired force profile. A rotary drive also provides a greater lifting force than a lifting magnet, while at the same time having a compact and lightweight design and efficient and reliable function.

In principle, the locking device can be used for sliding doors or windows.

In some exemplary embodiments, the locking device for an individual sliding sash is designed in other exemplary embodiments for locking several (for example two) parallel-displaceably mounted leaves.

In a preferred embodiment, the rotary drive is an electric motor. This motor can, for example, be controlled via PWM signals. Alternatively, hydraulic or other rotary drives could also be used.

In a further development, the locking device comprises a prestressing element which is designed and arranged such that the first locking element is under prestress in the locking position and / or in the unlocking position.

In another development, the locking device has an eccentric element rotatably supported by the rotary drive, the eccentric element being movable between a first and a second position by means of the rotary drive. The eccentric element is designed and arranged in such a way that the eccentric element on the movement into the first position on the first The locking element acts to move the first locking element into the locking position, and when moving into the second position acts on the first locking element in such a way that the first locking element moves into the unlocking position.

The eccentric element is preferably mounted directly, in particular non-rotatably, on the motor axis and is designed as a rotary lever. The eccentric element can be shaped in such a way that the rotational position-dependent force profile has an application-specific optimized profile. For example, a rotation axis distance can increase more slowly in the first rotation range than in the subsequent rotation range, so that a larger lever and thus a greater force are available in the first rotation range. The first range of rotation can be, for example, the first 15 ° to 45 °. Such a configuration can be advantageous, for example, if the displacement of the sliding sash requires more force for opening than for subsequent free displacement due to a retaining seal on the closing edge.

Stop buffers or damping elements can be provided for the rotary lever in the end positions. This increases the service life of the transmission. A pre-end stop circuit can also be provided.

The eccentric element thus makes it possible to adapt the force profile on the locking element through the shape of the eccentric element. The torque of the rotary drive can therefore be optimized via a gear and a cam-like element (here the eccentric lever) so that an application-specific, optimal course of movement and force is achieved.

Preferably, said preloading element preloads the first locking element against the action of the eccentric element. In other words, the biasing element presses the first locking element against the eccentric element. This ensures good contact between the eccentric element and the first locking element, and the prestressing element helps to return the locking element after it has been deflected by the eccentric element.

The biasing element can be a tensioning spring, in particular a leg spring with two legs. Alternatively, a compression spring, helical spring, evolute spring construction or other prestressing construction can also be used.

In a further development, the eccentric element is designed and arranged such that it lies in a dead center when the first locking element is in the Is locked position and / or in the unlocked position. The dead position reduces energy consumption (down to zero) and wear and tear, as the rotary drive is relieved. The dead position ensures a clearly defined bearing point and protects the drive. Moreover, despite the pretensioning effect described above, the first locking element cannot push the eccentric element out of its dead position, which creates additional security.

The multiple rotary drives can produce movements simultaneously or alternately. Preferably the two or more rotary drives are redundant, i. E. the rotary drives are independent of each other; if one fails, the other can move the first locking element alone according to the invention. Both rotary drives can therefore be designed to act on the same first locking element independently of one another. The redundancy can affect the mechanical as well as the electrical and electronic parts of the respective rotary drive. Here, the locking device can be developed such that each rotary drive has an associated eccentric element and / or gear. The rotary drives can therefore act on the first locking element via different or alternatively the same eccentric elements or gears. A non-positive transmission of movement from the gear to the first locking element can, for example, enable the gear to be operated independently of one another.

In another development, the first locking element is designed as a pawl. The pawl can, for example, be made as a tab from a piece of sheet metal. The pawl can be constructed in one piece and / or in several layers. The pawl preferably has a pivotable pawl section for the form-fitting contacting of a second locking element firmly connected to the sliding sash, for example a hook element.

The first locking element thus completes the second locking element in a form fit that fixes the desired position with the second locking element which is firmly connected to the sliding sash, preferably via its carriage to the sliding sash.

The pawl portion may include a pawl opening. Preferably, the pawl has a Y-shape, the trunk as a pawl section and the two arms as Bearing arms are used for storage in a housing of the locking device.

In a preferred development, the locking device further comprises one or more preferably self-sufficient electrical storage devices. This electrical storage device can preferably be one or more capacitors. Other electrical storage devices such as batteries, accumulators or other electrical storage devices can be used. The electrical storage device is used for the emergency movement of the first locking element between the locking position and the unlocking position. One or more electrical storage units are preferably assigned exclusively to each rotary drive in order to provide the redundancy. It is also conceivable that every rotary drive can access every energy store.

A plurality of redundant electrical storage devices, for example capacitors, are preferably included, with a maximum energy content of one or more of the electrical storage devices for at least one, preferably at least two, in particular exactly three guaranteed movements of the first locking element from the locking position to the unlocking position or vice versa. This ensures that the locking device can still perform a minimum of a predefined bolt movement even in the event of a power failure. This can be, for example, 1 to 10, preferably exactly 3 movements between the unlocking position and the locking position.

In order to expand the functionality, one or more manual unlocking devices, in particular at least one or precisely two Bowden cables, can also be included for manual movement of the first locking element between the locking position and the unlocking position. This also serves the application-specific design of the locking device or the system, which is based on the intended use. An emergency release can be attached to one side of the door. Depending on the door, one or no unlocking mechanism can be provided on only one side.

The development of the mechanical unlocking, in particular by means of a Bowden cable, makes it possible to provide two unlocking systems that function independently of one another. By operating a Bowden cable, for example, a toggle lever is moved, the movement of which causes the first locking element to move between the locking position and the unlocking position. The electronics can provide a switch which is activated when the mechanical release is actuated and when there is access to electrical energy, it sends a movement command to the door controller in order to move and lock electrically. If, on the other hand, the system is de-energized, the first locking element is moved mechanically via the toggle lever. The door leaves must then be moved manually.

As soon as the Bowden cable is relieved again, the first locking element resumes its original position before the mechanical actuation. The wings can then be moved manually if necessary. By appropriately designing the second locking element, the second locking element can also be brought into engagement with the first locking element when the latter is already in the locking position. E.g. the second locking element can be a hook element with a ramp, the ramp running onto the first locking element and moving it. The first locking element is simply moved back again via its bias as soon as the ramp has been passed and the locking is established. The system can thus be closed and locked without current.

The locking device can also have electronics, these electronics being set up to carry out a periodic error check of the locking device or parts thereof, with predetermined parameters or parameter groups being checked in a predetermined checking interval during the error check. In this error check, preferably at least a first and a second predetermined parameter or a parameter group with a first check interval of 1 second to 30 seconds, preferably 15 seconds, or with a second check interval of 1 hour to 48 hours, preferably 24 hours, be checked. A first parameter can, for example, be the responsiveness of the rotary drive, a latch position and its state, which can be transmitted to an alarm system, for example. A second parameter can be, for example, the energy content of an energy store.

In particular, the content of the electrical storage, the functionality of the individual components and / or the current leaf or locking position can be checked. This check further increases security through reliable error detection.

A failure of the external supply or the communication connection to the door control as well as the defect of a subsystem are recognized by the interlock and it a predefined action is initiated, e.g. an unlocking or locking of the door in the open or closed position. For this purpose, the relevant supplies and the function of the bus connection to the door control and between the two microcontrollers must be constantly monitored.

In a further development, the electronics can be developed in such a way that the at least two rotary drives can be operated redundantly. The locking electronics can therefore be completely redundant. With two electric motors, two bus transceivers, two microcontrollers and two output stages can be provided. The redundant locking system is supplied with regular function, e.g. by two external 24V supplies for the logic and for the motor bridge supply. The two supplies are used by the master and the slave subsystem.

The motor bridge supply can be switched separately with the simple lock, in order to prevent the lock from being unlocked if an error occurs when the escape and rescue route function is deactivated.

In this case, the at least two rotary drives are preferably designed to effect locking processes in a combined and / or alternating manner. An alternating use of the individual rotary drive extends the service life of the locking device, since each rotary drive causes fewer locking processes. The expression "alternately" encompasses both direct changes after each locking actuation and change after a large number of, for example, 2, 3, 5, 7, 10, 50, 100, 1000 actuations with one rotary drive before the same or a different number of actuations be carried out with the other rotary drive.

In addition, it is conceivable in embodiments with several rotary drives to install different or the same rotary drives. Different or identical gears or cams or eccentric elements can also be installed.

A joint use of the rotary drives can be called for if particularly difficult movements have to be carried out. Alternating use of the rotary drives can be used, for example, for smooth movements. Two rotary drives can also be used on a part of the movement, while otherwise only one rotary drive works.

With the present lock it is possible to realize a multitude of functions with a single locking device design, which is shown in is beneficial in some ways. This design can, for example, be used for stiff and smooth movements.

A standard (without escape and rescue function) or an escape and rescue door with trolleys or leaves, which can be locked in the closed position, can be implemented. It goes without saying that in this and in the following examples there are only one or two or more wings.

In the case of a double-leaf sliding door, the center, where both leaves meet in the closed position, can serve as the locking point. The carriage and / or the sliding sash can be locked at its upper edge or at its closing edge.

A standard or an escape and rescue door with trolleys or wings, which can be locked in the closed position, with the locking being constructed redundantly, can be implemented.

The "output locked" operating mode can be used here, whereby the redundant escape & rescue operation can be maintained. The opening command can be triggered by a monitored indoor sensor. Another operating mode is "locked at night", the sensors then being inactive and the opening command being able to be generated, for example, by means of a suitably placed and designed push button. The push button can be, for example, a green, monitored and illuminated push button.

A standard or an escape and rescue door with trolleys or wings, which are locked in the open position, can be implemented. This function keeps the wings in the open position, which can be used, for example, on motor boats in choppy waters.

An open position in an emergency can also be provided for fire doors, which if necessary should make the chimney effect usable for smoke extraction.

A standard or an escape and rescue door with trolleys or leaves, which can additionally or alternatively be locked in at least one intermediate position, can be implemented. This can be used with standard or escape and rescue doors. The opening path of the sash can be limited by locking in an intermediate position. An intermediate position solution can be used, for example, in locking systems for pharmacies in order to enable an additional option for full opening, namely that of a gap opening for night sales. Here, the first locking element can have a stop (on Point of full intervention) so that the opening path of the sash is limited.

A break-out lock can also be implemented, for example an escape and rescue door with rotating fitting, that is to say a combination of sliding and rotating wing door, being provided. A sliding sash, which also has the character of a rotary sash, is used for this. In the event of an escape, this wing can be swiveled out in the escape direction, which further reduces the obstruction to escape routes. In addition to the sliding system, a pivoting system is provided. The wing is then preferably locked via a push rod on the closing edge. Preferably, two counter-rotating rotary sliding leaves are provided, with locking of the two leaves against one another close to or on the closing edge and preferably also locking to the floor and / or the carriage. In addition, the rotating wings can be locked to the non-pivoting profile above the wing. The unlocking can be realized, for example, via a pushbar. In the "Night locked" operating mode, the escape and rescue function can also be maintained when the door is locked.

A standard or an escape and rescue door with a carriage or wing, which can be locked via a rod lock preferably attached to the closing edge of the wing, can be implemented. The first locking element, for example the pawl, can for example be provided with bayonet openings on the side. A rod lock can thus be implemented, with the locking rods being located in the sliding leaves and being automatically moved by the locking mechanism. Compared to today's solutions, where the rod drive is in the sliding sash and not stationary in the lock in the running profile, this would mean a great simplification. A portion of the glass on the door could also be enlarged, since the central lock does not have to be installed. Multi-point locking can also be implemented, preferably vertically to the floor.

A standard or an escape and rescue door with trolleys or wings, which can be locked via a hook lock preferably attached to the closing edge of the wing, can be implemented.

Fail safe and / or fail secure functions and other functions can also be implemented.

These functions can also be combined with one another where it makes sense.

The present invention also relates to a computer program product for a locking device as described above, wherein the computer program product comprises a computer program code, which computer program code, when executed in an integrated circuit, causes the integrated circuit to move the rotary drives in such a way that

• a standard door function, in particular a redundant standard door function, and / or

• an intermediate position lock, e.g. for pharmacists,
• and / or other functions mentioned above,
  realized or feasible.

The program position or function: "EXIT locked" means that a standard locking position is the one in which the door is locked. You cannot get inside the building from the outside; from the inside, the door is unlocked via an opening command (sensor, button, etc.), thus making it possible to leave the building.

Another aspect of the present invention is to specify a system, in particular a door system, comprising the at least one sliding sash, in particular a sliding door, for checking the building opening, at least one locking device for locking the at least one sliding sash, as described above. This system preferably comprises a computer program product as described above. The system can fix the sliding sash in a predetermined locking position and realize at least one of the above functions.

In each exemplary embodiment, the system can have one or more sliding panels and one or more locks and preferably include a computer program product as described above. In this case, for example, carriages and / or wings can be provided with a second locking element, which second locking element is in positive locking with the first locking element in the locking position. Both second locking elements can engage in the same first locking element.

Preferably, the locking device (s) are thus each arranged such that the locking position is an open position, a closed position or is an intermediate position of the sliding sash.

In a preferred embodiment, the at least one sliding sash has a closing edge, the system comprising at least one transmission element running essentially parallel to the closing edge, in particular a push rod, for transmitting the movement of the rotary drive (s), with the transmission element on its locking device side Section is operatively connected to the first locking element and is thus movable via the movement of the first locking element and is designed with the portion (s) remote from the locking device for locking the at least one sliding sash. The transmission element can then directly actuate a latch for engaging a floor recess (so-called floor locking) and / or for locking the closing edge via hook elements.

In one exemplary embodiment, the carriage can be locked and / or it is additionally or alternatively locked via the transmission element against the floor or against another fixed object or between wings converging towards one another. Multi-point locking can therefore be implemented.

In any case, a complex, expensive center lock, for example, can be avoided, which also has the advantage that a glass surface of the sash can be enlarged since no center lock has to be installed.

In general, the can be unlocked in the event of an escape or rescue via an emergency release, for example via Bowden cables or push bars.

In addition, one release lever per rotary drive can be provided for manual release. This lever can, for example, be arranged directly on the rotary drive shaft and can be rotated by 90 degrees or a little more for unlocking. If several motor gears are provided, each preferably has its own release lever. The unlocking can be electronically monitored so that unlocking takes place as soon as an unlocking lever is actuated.

Many exemplary embodiments have now been described, which serve to provide a better understanding of the invention. The various features of the exemplary embodiments can be combined to form further exemplary embodiments.

DESCRIPTION OF PREFERRED EMBODIMENTS

Based on Figures 1 to 14 A preferred embodiment of the carriage lock 10 according to the invention will now be described.

Figure 1 shows a sliding door system 1 with two glass sliding door leaves 2, 3 in the closed position for checking a building opening 5 in the passage direction D. The two sliding door leaves 2, 3 that can move in opposite directions are attached to carriage 40 (see Fig. Figures 12-14 ) with carriage wheels 8 (s. Figure 12 ) mounted displaceably in a horizontal running profile 4 along a closing direction S. The carriage lock 10 is arranged centrally in the longitudinal direction of the running profile 4. The carriages 40 are each provided with a second locking element, a hook element 80 (see Fig. Fig. 12 ), which is designed and arranged such that it can be caught by the carriage lock 10 (namely in the opening 132 of the pawl 13, see below) in order to effect the locking. The door leaves 2, 3 make contact along their main closing edges 20 and 30, respectively, which run in the vertical direction V, and have vertical secondary closing edges 21, 31. Figure 2 shows a perspective view of the carriage lock 10 obliquely from below. The carriage lock 10 comprises a frame-like chassis 11 as a housing, which in Figure 9 is shown on its own. The one-piece chassis 11 is a one-piece, U-shaped bent sheet metal with a flat bottom flap 111 and three flat side flaps 112-114 protruding perpendicularly from the bottom flap 111. The space formed between the tabs 112-114 is used to accommodate the various assemblies of the carriage lock 10 and is up in Fig. 2 covered by a pivotably mounted pawl 13.

The position specification " above " means: "latch side";"Below" means: "remote from the latch".

The first side flap 112 forms a first side surface of the carriage lock 10. In the first side flap 112 are downward (ie in Fig. 9 to the top) open recess 1121 with undercuts for receiving Bowden cables 15 (see below), or parts thereof, and cables 122 for supplying a microswitch unit 12 for monitoring the pawl 13. The cables 122 are received in a further undercut 1127 of the recess 1121. In addition, a plurality of through holes 1122-1126 are provided. These through holes 1122-1126 comprise an upper first pawl recess 1122, which is arranged close to the rear side (i.e. opposite the bottom flap 111) for receiving the pawl 13, two recesses 1123, 1124 for cylinder head screws 121 (see Fig. Fig. 3 ) of the microswitch unit 12 and two recesses 1125, 1126 for fastening the microswitch unit 12. Furthermore, a lateral projection 1128 with a free thickening at the end for fastening cables and an upper fastening lug 1129 protruding in the longitudinal direction of the bottom lug 111 for assembly purposes, e.g. by means of a Screw connection 9 through the bracket 1129, intended.

The second side plate 113 forms one of the first opposite, second side surfaces of the carriage lock 10. In the second side plate 113 are provided: an upper, near the edge at the rear and the first opposite arranged second pawl recess 1132 for receiving the pawl 13, a lateral projection 1138 with an end, free thickening for fastening purposes and an upper fastening tab 1139 running in the longitudinal direction of the bottom tab 111 for assembly purposes, for example by means of a screw connection 9 through the tab 1139.

The third side flap 114 runs parallel to and between the first and second side flaps 112, 113 and also has a downwardly open third recess 1141 with undercuts for receiving the Bowden cable, the undercuts of the recesses 1121 and 1141 being aligned with one another. Here, the third side flap 114 is arranged offset towards the second side flap 113.

The fastening straps 1129, 1139 have recesses into which screws 9 can be inserted for fastening the carriage lock 10 on or firmly relative to the track profile 4.

The pawl 13 is now with additional reference to FIG Figure 10 , which shows the pawl 13 on its own. The pawl 13 is designed as a one-piece bent sheet metal part and covers an upper opening of the U-shaped chassis 11 adjoining the bottom flap 111 between the first and second side flaps 112, 113. The pawl 13 is pivotably mounted in the pawl recesses 1122, 1132 and extends from these recesses 1122, 1132 to the bottom flap 111 and beyond the latter.

The pawl 13 has a Y-shape, with a distal pawl section 131 protruding towards and over the bottom flap 111 a trunk of the Y-shape and two arm sections 133, 134, which start in the proximal area of the pawl section 131, the arms of the Y- Form shape.

The pawl section 131 protrudes in its installed position at the end of the chassis U-shape to the front and essentially perpendicularly beyond the bottom flap 111 and has a square pawl opening 132 at its free distal end, into which hook elements 80 the carriage 40 (see Fig. Figures 12-14 ) can be intervened to determine.

At its proximal free end, the first arm section 133 has a free first pin element 1330 which protrudes against the first side tab 112, is designed to engage in the first latch recess 1122 and engages in a pivot bearing 135 (see Fig. Figure 3 ), with which the pawl 13 is pivotably mounted in the chassis 11. Another first pawl tab 1331 protruding from the first side tab 112 and from the pawl 13 and having a through hole 1332 is arranged distal from the first pin element 1330 on the arm section 133.

Figure 3 shows the lock 10 from above behind. A tension spring 14 with a central, hollow cylindrical winding section 140 and first and second tension spring legs 141, 142 which protrude therefrom and are arranged opposite one another and which can be resilient relative to the first about the axis of the hollow cylinder can be seen. The tension spring 14 is pushed with the coil section 140 in stock over this first pin element 1330, the first tension spring leg 141 engaging forwards on the rear edge of the first side plate 112 and the second tension spring leg 142 in the said through hole 1332 of the first latch plate 1331, with which the latch 13 is pivotable in the first pawl recess 1122 and preloaded by the tension spring 14 downwards, that is, against the locking position, is mounted in the first side plate 112 in the chassis 11.

The second arm section 134 in Fig. 10 has at its proximal end a free second pin element 1340 protruding against the second side tab 113, which is designed to engage the second pawl recess 1132 of the second side tab 113 and there also engages in a further pivot bearing 135 (see Fig. Fig. 3 ). The pawl 13 can thus be pivoted and is mounted in the frame 11 essentially perpendicularly to the bottom flap 111. A further second pawl flap 1341 protruding from the second side flap 113 and from the pawl 13 serves as an upper stop for a toggle lever of the Bowden cable 15 (see below).

The arm sections 133, 134 have a bending zone 1333, 1343.

Proximally laterally next to the protruding pawl section 131, through-openings 1310, 1311 are provided through the pawl 13, into which tongues with locking lugs of sliding plate elements 1312 protrude from below and are locked on the top (see also Fig Fig. 2 ). These sliding plate elements 1312 are, for example, made of polyoxymethylene, in particular of POM-500 AV (for example Delrin® 500 AF) or polyethylene, in particular of UHMW-PE (for example GUR®).

Between the first and third side flaps 112, 114, two first and second built-in dummies 1610, 1620 are arranged next to one another and screwed to the bottom flap 111 via countersunk screw connections 163, in which a first gear motor 161 and a second gear motor 162 are mounted (see Fig. Fig. 3 ). The geared motors 161, 162 are electric motors, preferably with a gear ratio as required, for example between 1:10 and 1: 10,000. The motor output is, for example, 1 watt to 200 watts, preferably 5 watts.

A first and second motor axis 1611, 1621 of the first and second geared motor 161, 162, respectively, run parallel to one another and protrude from the interior of the chassis 11 and perpendicularly through and beyond the bottom flap 111. A first and second rotary lever 171, 172 are arranged in a rotationally fixed manner on the axle sections 1611, 1621 protruding outwardly via the bottom flap 111 through recesses 1111 (see Fig. Fig. 2 ).

The rotary levers 171, 172 are designed as two-armed levers, each with a first lever arm 1711 or 1721 and an opposing second lever arm 1712 or 1722 (see Sect. Fig. 3 ). The rotary levers 171, 172 are fixed on the respective motor axis 1611, 1621 via a cylinder screw 173. The locking screws 173 reach through the respective rotary lever 171, 172 transversely to the corresponding motor axis 1611, 1621.

On the bottom flap 111, two each rotary lever 171, 172 screwed to the bottom flap 111 and protruding outward from there, cylindrically shaped and damping stop buffers 1110 are arranged as rotary motion limiters of the respective first lever arm 1711 or 1721. The two stop buffers 1110 are arranged so that the rotary lever 171, 172 moves from a first horizontal stop position Fig. 2 a rotation of, for example, 1 ° to 5 ° over the vertical direction V, that is, a rotation of, for example, 91 ° -95 °. This allows the rotary levers 171, 172 to be in a dead position in the vertical position.

The second lever arm 1712, 1722 has a rounded end face for bearing on the respective slide plate 1312, that is to say protrudes from the horizontal in the direction of rotation of the lever. The rotary lever 171, 172 is designed as an eccentric element so that in the first stable first position the rotary lever 171, 172 on the upper stop buffer 1110, that is, in the horizontal position Fig. 2 , and the sliding plate elements 1312 with the pawl 13 in the lower closed position on the end face of the second lever arm 1712, 1722 rest under tension of the tension spring 14. When the first lever arm 1712, 1722 rotates the rotary lever 171 or 172 by slightly more than 90 ° to the opposite lower stop buffer 1110 into the second position, the vertical position, the second lever arm 1712 or 1722 sliding along the sliding element 1312 presses due to its eccentric rounding Shape the sliding plate element 1312 and thus the pawl 13 successively away from the axis 1611, 1621 of the motor 161 or 162, so that the pawl 13 is pivoted in the pivot bearings 135 and the pawl section 131 moves out of the locking position (solid reference line in Fig. 12 ) up to an unlocking position releasing the carriages 40 (dashed reference number line 13 in Fig. 12 ). Figure 12 thus shows the pawl 13 in both positions relative to the hook elements 80 of the carriage 40.

The rotation of the rotary levers 171, 172 into the vertical position by a little more than 90 ° causes the rotary lever 171, 172 to be in the said dead position in the second position. Thus, the gear motor 161 or 162 does not have to be in the first position (horizontally oriented rotary lever 171, 172 on the upper stop buffer 1110 and pawl 13 on the upper edge of the frame 11 or indirectly on the buffer 1110) nor in the second position (vertically oriented Rotary levers 171, 172 in dead position on the lower stop buffer 1110) use energy to hold the position, which is energy-efficient and advantageous in terms of safety.

Moreover, it can be seen from the drawings that the rotary levers 171, 172 can be skeletonized, which saves material. The rotary levers 171, 172 can be produced, for example, by a zinc die-casting process.

A main board 18, which extends between the first and second side flaps 112, 113 and parallel to the bottom flap 111 of the chassis 11, is arranged delimiting the interior of the U-shape of the chassis 11 towards the rear. The board 18 is in the Fig. 3 and in the Figures 7 & 8 and connected via screw connections 183 to the installation dummies 1610, 1620 or the motors 161, 162. The motor axes 1611, 1621 break through the plate 18 and protrude over the outer surface of the plate. An actuating lever 181, 182, which is clamped to the corresponding axle 1611, 1621 via a locking ring 184, is attached to each of these protruding sections. The first and second actuating levers 181, 182 are each designed with one arm, with a permanent magnet 185 in the free end of the arm, which throws its magnetic field against the board 18, is housed.

Since the actuating levers 181, 182 - like the rotary levers 171, 172 - are attached to the respective motor axis 1611, 1621 in a rotationally fixed manner, the actuating levers 181, 182 have the same range of motion, i.e. they are slightly more than 90 ° between the stop buffers 1110 rotatable. In the end positions of the actuating levers 181, 182, an outer Hall sensor 186 is attached between the permanent magnet 185 and the circuit board 18. Correspondingly, two outer Hall sensors 186 assigned to the end positions are provided for each actuating lever 181, 182 and are arranged in a circle. Conductor tracks 187 for operating the Hall sensors 186 are visible. In order to provide a pre-end stop circuit, two inner Hall sensors 188 are arranged between the outer Hall sensors 186, which announce to the electronics of the carriage lock 10 that the lever 181, 182 is approaching one of its end positions.

In addition, further electronic components such as microcontroller 189 and print connector 1890 and the like are on the circuit board 18. intended.

An energy store 21, 22 can be attached via the print connector 1840. Two independent, i.e. redundant, capacitors 21, 22 with a sufficient capacity of 5,000 microfarads to 100,000 microfarads are provided as energy stores 21, 22, which are arranged on a separate circuit board 200 (see Fig. Figure 11 ). The energy store 21, 22 supplies energy which can be fed to the geared motors 161, 162, the energy for up to three unlocking or locking movements, with one energy charge. Here, exactly one capacitor 21 or 22 is assigned to each geared motor 161, 162.

The power supply and communication with the main control takes place via the print connector 1890.

As a further manual unlocking option, a Bowden cable 15 is provided with a knee-shaped unlocking lever 151, which is now based on the Figures 4-6 is described. The unlocking lever 151 is pivotably mounted on an axis of rotation 152 under the second pawl bracket 1341 of the pawl 13 on the third bottom bracket 111 in the chassis 11. A first toggle lever arm 1511 protrudes downward and has two receptacles 153 for two Bowden cables 154, 155 running parallel to one another in the lower chassis area. The receptacles 153 are each provided with adjusting screws 156, with which the Bowden cable 15 can be adjusted. The Bowden cable 154, 155 each run through the undercuts of the first and third recesses 1121, 1141 of the first and third side tabs 112 and 114, respectively. The pull cables 154, 155 are screwed to the third side tab 113 via hexagon nuts 157, with one or two compression springs 158 being tensioned between the toggle-lever-near nuts 157 and the first toggle lever arm 1511, which tensioning the release lever 151 in the starting position (closed position) (s. Fig. 4 ). The second toggle arm 1512 protrudes upward from the pivot 152 and provides a contact portion 1513 which is in contact with the lower surface of the second latch tab 1341 ( Figures 5, 6 ).

If the Bowden cable 15 is now activated, the compression springs 158 are compressed and the release lever 151 about the axis of rotation 152 from the initial position ( Fig. 6 ) to the actuation position ( Fig. 5 ) is pivoted, the contact section 1513 pressing upwards against the second pawl tab 1341 and thus pivoting the pawl 13 from the locking position against the tension spring 14 into the unlocking position.

Another microswitch assembly 19 for monitoring the unlocking lever 151 is fastened to the bottom bracket 111 via a screw connection 193 and a holder plate 194, supply lines 195 being provided to control the assembly 19.

Figures 13 and 14 show a further embodiment with a push rod lock with two push rods 6, which run along the main closing edges 20, 30 in the respective wing 2 and 3, respectively. The wings 2, 3 are each slidably mounted on two carriages 40 in the profile rail 4 and shown in the closed position. The carriage lock 10 is now mounted centrally in the profile 4 and coupled to the push rods 6 in an upper section 61, for example via a bayonet lock, that a movement of the locking element 13 out of the locking position according to Fig. 14 in the unlocking position according to Fig. 13 pulls the rods 6 vertically upwards. In the locked position after Fig. 14 the system 1 is locked, because the push rods 6 engage with free ends 62 in floor recesses 600 in the floor 60 in a form-fitting manner for a multi-point locking. These floor recesses 600 can be reinforced accordingly. If it is now unlocked, the pawl 13 moves upwards and pulls the push rods 6 vertically upwards out of the base recesses 600, see FIG. Fig. 13 . At the same time, the mechanical coupling between the pawl 13 and the push rods 6 is released so that the wings 2, 3 can be pivoted or pushed open. The push rod 6 in Closed position, that the inner rotating sashes are swiveled out and that the outer sliding sashes 2, 3 are pushed open.

Additionally or alternatively, the push rods 6 can also effect a locking along the main closing edges 20, 30. Figures 15 and 16 show a lock with a single push rod 6 and a central swivel bolt 63 which is attached to the main closing edge 30.

In Fig. 15 the pawl 13 is in the release position, with which the push rods 6 are pulled up and the hook element 63 coupled to the push rod 6 is not in engagement with the counter element on the other main closing edge 20; the door is therefore unlocked.

In Fig. 16 the pawl 13 is in the closed position, with which the push rod 6 moves the hook element 63 to engage the other main closing edge 20 and thus locks the door. Only one push rod 6 is therefore necessary. Several hook elements 63 can also be provided over the main closing edge 20, 30 and / or several push rods 6. Swivel bolts 63 can also be provided on both closing edges 20, 30, which are designed to engage the other closing edge 30, 20. In addition, ground engagement with the push rod (s) 6, as mentioned above, can be realized.

Correspondingly, a simple and inexpensive multi-point locking, which can extend into the floor 60, can be implemented along the main closing edges 20, 30. No center locks are necessary for this, which allows, for example, a glass surface of the door leaf to be enlarged, since no center lock has to be integrated.

Also on the secondary closing edges 21, 31 (s. Fig. 1 ) the sliding sashes can be locked using locking elements using one or more push rods 6.

Instead of a door system 1, the present invention can also relate to a window system, the sash then being a window sash and not a door sash.

It should be noted that a lock for a sliding door system 1 without a carriage 40 can be constructed in the same way, with the second locking element then being fastened directly or indirectly to the leaf 2, 3. The second locking element can also be, for example, a push rod 6, which runs along the main closing edge of the door and in the locking position extends into a recess in the floor, the push rod being pulled out of the floor recess during the unlocking movement so that the door is unlocked. <b> REFERENCE CHARACTERISTICS LIST </b> 1 Sliding door system 1141 third recess 2.3 Sliding door leaf 20, 30 Main closing edge 12th Microswitch element 21, 31 Secondary closing edge 121 screw 4th Running profile 122 electric wire 40 Carriage 5 Building opening 13th pawl 131 Latch section 10 Carriage lock 1310.1311 Through hole in 13 1312 Sliding plate element 11 chassis 111 Bottom flap of 11 132 Latch opening 1110 Stop buffer 1111 Recess for motor axis 133 first arm section of 13 1330 first pin element 1112 Mounting recess 1331 first latch tab 112 first side flap of 11 1332 Through hole 1121 first recess 1333 Bending zone of 133 1122 first latch recess 1123.1124 Recess for 12 134 second arm section of FIG 1125.1126 Mounting recesses 1340 second pin element 1127 further recess 1341 second latch tab 1128 lateral protrusion 1343 Bending zone of 134 1129 Fastening tab 135 Pivot bearing 113 second side flap of 11 1132 second latch recess 14th Tension spring 1138 lateral protrusion 140 Winding range from 14 1139 Fastening tab 141 first leg of 14 142 second leg of 14 114 third side flap of 11 15th Bowden cable 184 Locking ring 151 Release lever 185 Permanent magnet 1511 first knee lever arm 186 external hall sensor 1512 second knee lever arm 187 Track 1513 Contact section of 1511.1512 188 inner hall sensor 189 Microcontroller 152 Axis of rotation 1840, 1890 Print connector 153 admission 154.155 Pull cable 19th Monitoring group for 151 156 Adjusting screw 193 Screw connection 157 Hexagon nut 194 Holder plate 158 feather 195 management 161 first gear motor 21st first electric storage 1610 Built-in dummy for 161 22nd second electric storage 1611 Axis of 161 200 circuit board 162 second gear motor 1620 Built-in dummy for 162 6th Push rod 1621 Axis of 162 60 ground 163 Screw connection with 111 600 Floor recess 61 Section of 6 on the carriage locking side 171 first rotary lever 1711 first lever arm of 171 62 Section of 6 1712 second lever arm of 171 172 second rotary lever 63 Swivel bolt 1721 first lever arm of 172 1722 second lever arm of 172 8th Carriage wheel 173 Locking screw 80 Hook element 18th Circuit board with electronics D.
