Description

The technical field to which the invention relates

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

State of the art

EP 2 607 580 discloses a stopper for a sliding door system for controlling access to a building through a doorway. The leaf of the sliding door is suspended on a carriage, while the said carriage together with the leaf is movable in a guide profile located above the leaf to close or open the doorway of the building. In order to fix the sash in the desired position on the guide profile, the locking device, which is fixed relative to the guide profile, contains a locking pin that can move between the stopping position and the unlocking position, and which interacts with the carriage plate to fix the carriage in the guide profile.

The locking device and the carriage are made in such a way that in the specified required position the locking pin and the gripping plate on the side of the carriage are oriented so that the locking pin, when moving to the locking position, engages with the specified plate and locks the carriage in the guide profile.

The driving element for the locking pin is a lifting magnet with a magnetically movable armature, whereby a pressure spring is also provided which counteracts the magnetic force to return the armature or the armature.

The disadvantage of such a system is that the nature of the change in the force of the lifting magnet largely depends on the position of the armature, and the nature of the change in the force of the lifting magnet and the nature of the change in the force of the pressure spring do not have optimal coordination with each other.

Disclosure of the essence of the invention

The object of the present invention is to eliminate the above disadvantages and to provide an improved locking device, in particular a device for locking the carriage of a sliding leaf, in particular a sliding door.

This problem is solved by the locking device according to paragraph 1 of the claims. In accordance with it, there is proposed a locking device, in particular a carriage locking device, for at least one sliding sash, in particular for a sliding door, for controlling access to a building through a doorway, wherein said locking device is configured to lock at least one sliding sash, and the specified locking device contains:

a first locking element movably mounted,

a drive device for moving the first locking element between the unlocking position and the locking position,

wherein said drive device is a rotary drive.

The locking element can be a bolt, latch, or, in the general case, some reciprocal element, which can be engaged in positive engagement with respect to the direction of movement with the corresponding element of the carriage or sliding flap. The locking element is preferably designed so that its movement between the unlocking position and the locking position is a pivotal or rotational movement.

In the context of the present invention, the expression "between the unlocking position and the locking position" includes movement to both the unlocking position and the locking position, unless the context otherwise indicates.

Alternatively, a structure can be provided that allows this movement to be performed as a translational movement or shear, or as a combination of rotation and shear.

The present invention is based on the fact that a rotary actuator can be used to operate the locking device. The specified rotary drive with the help of a gearbox can be optimally adapted to the nature of the change in force, which is required in a particular application. The known lifting magnet generates a relatively small lifting force when the armature is extended, which increases with a gradual reversal of the armature. This type of force variation depending on the position of the armature is disadvantageous and can be corrected by means of a rotary drive, in particular a gear motor, especially preferably an electric motor, preferably with a series-connected gearbox. An embodiment is also possible in which the engine acts on the locking element through the cam to obtain the required force pattern. At the same time, the slewing drive provides a higher lifting force than the lifting magnet, as well as a more compact and lighter structure and more efficient and reliable operation.

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

In some embodiments, the locking device is configured to lock an individual sliding flap, while in other embodiments, to lock multiple (eg, two) parallel slides.

In one preferred embodiment, the rotary actuator is an electric motor. Such a motor can be controlled, for example, with pulse width modulation signals. Alternatively, hydraulic or other rotary actuators can also be used.

In one improved embodiment, the locking device comprises a tensioning element which is designed and positioned such that the first locking element is tensioned in the locking position and / or in the unlocking position.

In another improved embodiment, the locking device comprises an eccentric element rotatably mounted by a rotary actuator, the rotary actuator being able to move said eccentric element between the first and second positions. This eccentric element is made and arranged in such a way that when it is moved to the first position, it is possible to move the first locking element to the locking position, and when it is moved to the second position, it is possible to move the first locking element to the unlocking position.

The eccentric element is preferably mounted directly on the motor shaft, in particular without the possibility of rotation relative to it, and has the form of a pivot arm. The eccentric element can be designed in such a way that the characteristic of the change in force depending on the pivot position is optimized for specific conditions of use. So, for example, the distance to the pivot axis in the first pivot range may increase more slowly than in the next pivot range, so there is more leverage in the first pivot range and therefore more force. The first pivot range can be, for example, the first 15 ° -45 °. Such a design option can be useful, for example, if, due to the retaining seal at the closing edge, the sliding of the sliding sash requires more force to open than for subsequent free movement.

Stops or shock absorbers can be provided for the pivot arm in the end positions. This increases the durability of the gearbox. In addition, an end stop warning device can also be provided.

The shape of the eccentric element allows you to adjust the nature of the change in the force on the stopper element. The torque of the slewing drive can also be optimized with a gearbox and a curved element (in this case, an eccentric lever) to provide a movement and force behavior that is optimal for the application.

Preferably, said tension member provides tension to the first locking member against the action of the eccentric member. In other words, the tensioning element pushes against the first locking element against the eccentric element. Thus, good contact is ensured between the eccentric element and the first locking element, while the tensioning element assists in returning the locking element after it has been moved by the eccentric element.

The tensioning element can be a tensioning spring, in particular a double-arm coil spring. Alternatively, compression spring, coil spring, evolute spring and other tensioning structures can also be used.

In one improved embodiment, the eccentric element is configured and positioned such that it is at dead center when the first locking element is in the locking position and / or in the unlocking position. This dead center position reduces energy consumption (down to zero) and wear because the slewing drive is unloaded. The dead center position provides a precisely defined fulcrum and protects the drive from stress. In addition, the first locking element, despite the above-described tensioning effect, cannot move the eccentric element from the dead center position, which provides additional reliability.

In one improved embodiment, the locking device comprises two or more of these rotary actuators. These multiple drives can simultaneously or alternately provide movements. These two or more rotary actuators are preferably mutually redundant, i. E. the rotary drives are independent, and if one of them fails, the other can separately move the first locking element according to the invention. Thus, both rotary actuators can independently move the same first locking element. The redundancy may apply to the mechanical as well as the electrical and electronic parts of the respective slewing drive. In this case, the locking device can be improved in such a way that each rotary actuator is associated with one specific eccentric element and / or gearbox. Rotary drives can also act on the first locking element by means of different or - alternatively - the same eccentric elements or gearboxes. The force-locked motion transmission from the gearbox to the first locking element can enable, for example, the gearboxes to operate independently from each other.

In another improved embodiment, the first locking element is in the form of a latch. The latch can be made, for example, in the form of a plate of metal sheet material. The latch can be of one-piece and / or multi-layer construction. The latch preferably comprises a pivotable latch part which is designed to be positively engaged with a second locking element fixedly connected to the sliding flap and which may be, for example, a hook element.

The first locking element is also supplemented with a second locking element, which is fixedly connected to the sliding flap, preferably through its carriage, and with which a positive-locking connection is formed, which fixes the required position.

The latch part may include a latch hole. The latch is preferably Y-shaped, with the barrel Y serving as the latching part, and the two upper branches Y as supporting strips for installation in the stopper body.

In one preferred, improved embodiment, the locking device also comprises one or more, preferably self-contained, electrical energy storage devices. These stores of electrical energy can preferably be one or more capacitors. Other electrical energy storage devices can also be used, such as batteries, accumulators or the like. The electrical energy storage device serves to move the first locking element between the locking position and the unlocking position in an emergency. Preferably, one or more electrical energy storage devices are dedicated to each rotary actuator in order to provide redundancy. An embodiment is also possible in which each rotary actuator has access to all electrical energy stores.

Preferably, there are several mutually redundant electrical energy stores, for example capacitors, whereby the maximum energy content in one or more electrical energy stores is sufficient for at least one, preferably at least two, particularly preferably exactly three, movements of the first locking element from the locking position release position, or vice versa, in an emergency. In this way, even in the event of an interruption in the power supply, it is ensured that the locking device can perform a minimum of predetermined locks and releases. So, for example, it is possible to perform from 1 to 10, preferably exactly 3 movements between the unlocking position and the locking position.

In order to expand the functionality, in one improved embodiment, one or more manual release devices can also be provided, in particular at least one or exactly two Bowden cables, for manually moving the first locking element between the locking position and the unlocking position. Such hand-held devices are also used to tailor the locking device or system for the intended use. One emergency release device can be installed on one side of the door. Depending on the version of the door, one emergency release device may also be provided on only one side of the door, or such a device may not be present at all.

In an improved embodiment of the mechanical release device, in particular with the use of a Bowden cable, two release systems are provided that function independently of each other. By acting on the Bowden cable, for example, a movement of the crank arm takes place, which in turn causes the movement of the first locking element between the locking position and the unlocking position. In this case, a switch can be provided in the electronic circuit, which is activated when the mechanical release device is actuated and, if there is access to electrical energy, sends a movement command to the door drive control system in order to provide movement and locking using electricity. Conversely, if the system is de-energized, the first locking element is mechanically moved by the crank. The door leaves can then be moved manually.

After releasing the Bowden cable, the first locking element returns to its original position, which it occupied before the mechanical action. In this case, the sashes can be moved manually. Due to the appropriate design of the second locking element, it can be brought into engagement with the first locking element when the latter is already in the locking position. Thus, for example, the second locking element can be a hook element with an inclined portion, said inclined portion engaging and moving the first locking element. Due to the tension, the first locking element returns to its place as soon as the inclined section moves further, while locking is carried out. Thus, the system can be closed and locked in the absence of current.

The locking device may also contain an electronic unit that provides periodic checking of the presence of malfunctions of the locking device or its parts, and when checking for faults, it is possible to verify predetermined parameters or groups of parameters with specified calibration intervals. With such a check for faults, it is possible to verify preferably at least one first and one second predetermined parameters or a group of parameters with a first calibration interval of 1 to 30 seconds, preferably 15 seconds, or a second calibration interval of 1 to 48 hours, preferably 24 hours. The first parameter can be, for example, the efficiency of the slewing drive, the position of the latch and its state, which can be transmitted, for example, to the voice alarm system. The second parameter can represent, for example, the amount of energy in the storage of electrical energy.

It is also possible to monitor the charge level of the electrical energy storage device, the functionality of the individual components and / or the current position of the sash or stopper. This inspection improves reliability by reliably detecting defects.

A failure in the external power supply or communication line for controlling the door, as well as a defect in a system component, is recognized by the locking device, and a predetermined action is taken, for example, to unlock or lock the door in an open or closed position. For this, it is necessary to constantly monitor the corresponding power supply and the functionality of the bus connection for door control and between the two microcontrollers.

In a further embodiment, the electronic unit is improved in that it is possible to operate at least two rotary actuators in a mutually redundant manner. The system locking electronics can also be fully redundant. With two motors, two bus transceivers, two microcontrollers and two output stages can also be provided. The redundant stopping system, during regular operation, is provided, for example, with two external 24 V power supplies for the power supply of the logic circuits and the motor supply bridge. Both power supplies are used by the master and slave subsystems.

The engine supply bridge in a simple embodiment of the locking device can be connected separately in order to prevent the locking device from unlocking when the emergency evacuation function is inactive in the event of a malfunction.

In this case, at least two rotary drives are preferably provided for the joint and / or alternate implementation of the locking processes. The alternating use of separate rotary actuators increases the longevity of the locking device as each rotary actuator performs fewer locking processes. The term "alternate" includes both a direct change after each locking, and a change after a certain number, for example, 2, 3, 5, 7, 10, 50, 100, 1000 operations of one rotary actuator before the same or another number of actuations with another rotary actuator.

In addition, in embodiments with multiple rotary drives, different or identical rotary drives can be used. In this connection, different or identical gearboxes, cams or eccentric elements can also be used.

Sharing rotary actuators may be necessary when movements with particularly tight strokes are required. Alternating use of rotary drives is possible, for example, for easy-to-move movements. It is also possible to use two rotary drives in one travel section, while only one rotary drive operates in the rest of the travel.

The present invention allows many functions to be implemented in one design of the locking device, which is useful from various points of view. So, for example, this design can be used for tight travel and easy travel.

In this case, both standard doors (without an emergency evacuation function) and evacuation doors with a carriage or a sash can be implemented, which are made with the possibility of unlocking in a closed position. It should be understood that one, two or more flaps may be provided in this and the following examples.

In particular, in the case of a double-leaf sliding door, the center can serve as a locking point, where the two leaves are connected in the closed position. In this case, the carriage and / or the sliding flap can be locked at its upper edge or closing edge.

In this case, a standard door or an evacuation door can be implemented, which has a carriage or flap made with the possibility of unlocking in the closed position, and the locking device is redundant.

The locking device according to the invention can have the "Output blocked" mode of operation, while it is possible to maintain a backup emergency evacuation mode. The open command can be issued by a follow-up internal sensor. Another mode of operation is "Night blocking", whereby the sensors are inactive and an opening command can be generated, for example, by means of a push button of appropriate mounting location and design. Such a push button can be, for example, a green backlit control key.

In this case, a standard door or an escape door can be realized, having a carriage or a leaf that locks in the open position. This function keeps the sash in the open position, which can be useful, for example, in motor boats in the event of rough seas.

In addition, an emergency open position can be provided for fire doors, which must provide an exhaust effect to remove smoke.

A standard door or an escape door can also be implemented having a carriage or flap that can additionally or alternatively be locked in at least one intermediate position. This can be used for both standard doors and escape doors. In this case, the length of the opening stroke of the sash can be limited, at which it can be locked. Such a solution with an intermediate position can be used, for example, in door locking systems for pharmacies to provide an additional alternative to full opening, namely partial opening for overnight sales. In this case, the first locking element can have a stop in the locking position (at the point of full engagement), so that the length of the opening stroke of the sash is limited.

An emergency stopping device can also be implemented, for example for an escape door with pivoting hinges, as well as for a combination of a sliding and a swing door. For this purpose, a pivotable sliding sash is used. In the event of an evacuation, this leaf can be rotated in the direction of the exit, which further reduces the obstacle in the direction of the evacuation. An additional rotary system is provided for the sliding system. In this case, the sash is preferably locked on the side of the closing edge by means of a sliding bar. In this case, two oppositely displaceable swing-and-slide flaps are preferably provided, which can be locked relative to each other near or on the side of the closing edge, and their locking relative to the floor and / or carriage is also provided. In addition, the pivoting sashes can be locked against a fixed profile located above the sashes. The release can be carried out, for example, by means of a "pushbar" lever. In "Night Lock" mode, the emergency evacuation function can also be supported when the door is locked.

A standard door or an escape door with a carriage or sash can be realized, which can be locked by means of a pivot locking device, preferably mounted on the closing edge of the sash. The first locking element, for example a latch, can be provided, for example, on the sides with holes for a bayonet connector. Due to this, it is possible to carry out a rod locking, in which the locking rods are located in the sliding doors and are automatically moved by the locking device. In contrast to the known solutions, according to which the rod drive is located in the sliding leaf and not stationary in the guide profile of the locking device, this would mean a significant simplification. At the same time, you can also increase the glass area of the door due to the absence of the need to install an internal lock. In addition, it is also possible to implement the locking at several points, preferably also perpendicular to the floor.

It is possible to implement a standard door or an escape door with a carriage or sash, which can be locked by means of a hook locking device, preferably mounted on the closing edge of the sash.

The functions Fail Safe (preservation of full or partial operability in the event of failure of individual elements or the control system) and / or Fail Secure (automatic locking in the event of a power outage), as well as other functions, can also be implemented.

If appropriate, these functions can be combined with each other.

The present invention also relates to a computer program product for a locking device as disclosed above, said computer program product comprising a computer program code, when executed in an integrated circuit, the integrated circuit causes a movement of the rotary actuator such that it can be realized or realized:

- the function of a standard door, in particular the backup function of a standard door, and / or

- the emergency evacuation function, in particular the emergency evacuation backup function, in particular in conjunction with the program setting "Exit blocked", and / or

- locking the door in an intermediate position, for example in the case of pharmacies, and / or

- other above functions.

In this case, the software setting or function: "Output blocked" means the standard setting in which the door is locked. It is impossible to get inside the building from the outside, from the inside, upon an opening command (sensor, switch, etc.), the door is unlocked, and thus the exit from the building is provided.

Another aspect of the present invention is a system, in particular a door system, comprising at least one sliding sash, in particular a sliding door, for controlling access to a building through a doorway by means of at least one stopping device designed to stop said at least one sliding sash as described above. This system preferably contains the computer program product described above. At the same time, this system can fix the sliding leaf in a predetermined locking position and implement at least one of the above functions.

In each embodiment, the system may comprise one or more sliding flaps, one or more retaining devices, and preferably one computer program product as disclosed above. In this case, for example, the carriage and / or the flap can be provided with a second locking element, which in the locking position forms a positive connection with the first locking element. The two second locking elements can be engaged with the same first locking element.

One or more locking devices are arranged so that the locking position is an open position, a closed position or an intermediate position of the sliding leaf.

In one preferred embodiment, said at least one sliding sash comprises a closing edge, wherein the system comprises at least one transfer element movable substantially parallel to the closing edge, in particular a sliding rod, for transferring movement from one or several rotary actuators, while the transfer element, with its part located on the side of the locking device, is functionally connected to the first locking element and therefore can be moved when the first locking element moves, and one or more parts opposite to the locking device ensures the locking of the specified at least one sliding sash. The transfer element can directly actuate the stopper to engage it with a recess provided in the floor (so-called floor stopping) and / or to block the closing edge by means of a hook element.

In one embodiment, the carriage can be locked and / or locked by means of a transfer element relative to the floor or other stationary object, or additionally or alternatively between converging flaps. Multi-point locking can also be realized.

In any case, the use of a laborious and expensive mortise lock can be eliminated, which makes it possible to increase the glazing surface of the sash, since the installation of a mortise lock is not required.

In this case, the release in the event of an emergency evacuation can be carried out using an emergency release device, for example, Bowden cables or lever levers of the "pushbar" type.

In addition, a release lever can be provided for each rotary actuator for manual release. This lever can be located, for example, directly on the shaft of the rotary actuator, and can be rotated 90 degrees or more to provide release. In the event that several geared motors are provided, each of them preferably comprises a release lever. The release can be monitored by an electronic unit to ensure release when the release lever is actuated.

The above is a description of several embodiments that serve to better understand the invention. In this case, various features of the embodiments can be combined to obtain other embodiments.

Implementation of the invention

FIG. 1-14 show a preferred embodiment of a carriage locking device 10 according to the invention.

FIG. 1 shows a sliding door system 1 with two glazed sliding leaves 2, 3 in a closed position to control access to the building through the doorway 5 in the direction D of the passage. Two flaps 2, 3 sliding in opposite directions are mounted on carriages 40 (see Fig. 12-14) with wheels 8 (see Fig. 12) with the possibility of sliding in the closing direction S in the horizontal guide profile 4. In the center in the longitudinal direction of the guide profile 4 there is a carriage locking device 10. The carriages 40 are provided with a second locking element, namely a hook element 80 (see Fig. 12), which is designed and located so that it can be gripped by the carriage locking device 10 (in particular, the hole 132 of the latch 13, see below), so that provide stopping. The door leaves 2, 3 contact each other along their main closing edges 20, 30 extending in the vertical direction V and comprise vertical minor closing edges 21, 31. FIG. 2 is an oblique perspective view from the bottom of the carriage locking device 10. The carriage locking device 10 comprises a frame chassis 11 as a housing, which is shown separately in FIG. 9. The one-piece chassis 11 is a one-piece U-shaped bent edged metal sheet with a flat bottom plate 111 and three flat side plates 112-114 projecting perpendicular to the bottom plate 111. The space formed between the side plates 112-114 serves to accommodate the various components of the carriage locking device 10 and is closed at the top, as shown in FIG. 2, rotary latch 13.

The indication of the position "from above" means: "from the side of the latch", "from the bottom" means: "from the side opposite to the latch".

The first side plate 112 forms the first side surface of the carriage locking device 10. The first side plate 112 is provided with an open downward (ie, upward in FIG. 9) recess 1121 with undercuts for positioning the Bowden cables 15 (see below) or parts thereof and cables 122 for powering the microswitch 12 to track the latch 13. When the cables 122 are then inserted into the other undercut 1127 of the recess 1121. In addition, a plurality of through holes 1122-1126 are provided. These through-holes 1122-1126 include an upper first latch recess 1122 located near the rear side (i.e., opposite the bottom plate 111) for receiving latch 13, two recesses 1123, 1124 for pan head screws 121 (see FIG. 3) microswitch 12 and two fastening recesses 1125, 1126 for fastening microswitch 12. Further, there is a side protrusion 1128 with an end free thickening for fastening cables and an upper fastening tongue 1129 protruding in the longitudinal direction of the bottom plate 111 for installation purposes, for example, by means of a screw connection 9 passing through the tongue 1129.

The second side plate 113 forms a second side surface of the carriage locking device 10 opposite the first. Provided on the second side plate 113 are: an upper second latching recess 1132 located near the rear edge and opposite to the first recess for inserting the latch 13, a side projection 1138 with an end free bulge for fastening purposes, and an upper fastening tab 1139 extending in the longitudinal direction of the bottom plate 111 for mounting purposes, for example, by means of a screw connection 9 passing through the tongue 1139.

The third side plate 114 runs parallel to the first and second side plates 112, 113, is located between them, and also contains an open bottom third recess 1141 with undercuts for the location of the Bowden cable, while the undercuts of the recesses 1121 and 1141 are oriented relative to each other. The third side plate 114 is offset from the second side plate 113.

The fastening tongues 1129, 1139 contain recesses into which the screws 9 can be inserted for fastening the carriage locking device 10, or can be fixedly mounted relative to the guide profile 4.

Latch 13 is shown separately in FIG. 10. It is an integral part bent from a metal sheet and closes the upper opening of the U-shaped chassis 11 adjacent to the bottom plate 111 between the first and second side plates 112, 113. The latch 13 is pivotally installed in the latch recesses 1122, 1132, extends through these recesses 1122, 1132 to the bottom plate 111 and protrudes from it.

The latch 13 has a Y-shape, while the distal latch part 131 protruding to the bottom plate 111 and above it forms a Y-shaped barrel, and the two side parts 133, 134, which are located in the proximal region of the latch part 131, form Y-shaped forms.

The latch part 131 in its end mounting position on the U-shaped chassis protrudes forward, is located substantially perpendicular to the bottom plate 111 and includes at the free distal end a quadrangular latch hole 132 with which hook elements 80 of the carriage 40 ( see Fig. 12-14) to fix them.

The first side portion 133 at its near-center free end comprises a free first pin element 1330 protruding towards the first side plate 112, adapted to engage with the first latching recess 1122 and mounted in a pivot bearing 135 (see Fig. 3), thus, the latch 13 is pivotally mounted in the chassis 11. Also projecting to the first side plate 112 from the latch 13, the first latch tab 1331 with a through hole 1332 is located further from the first pin member 1330 on the side portion 133.

FIG. 3, the locking device 10 is shown from the top from the rear. At the same time, a tension spring 14 with a central coil part 140 in the form of a hollow cylinder and protruding from it opposite to each other the first tension spring arm 141 and the second tension spring arm 142, spring-loaded relative to the first around the axis of the said hollow cylinder, are visible. A tension spring 14 is mounted by a coiled portion 140 on a first pin member 1330, with the first tension spring arm 141 engaging the trailing edge of the first side plate 112 and the second tension spring arm 142 engaging the through hole 1332 of the first latch tab 1331, so that the latch 13 is pivotally mounted in the first latch recess 1122 and is pressed downward by the tension spring 14, i.e. into the locking position, on the first side plate 112 of the chassis 11.

The second side portion 134, as shown in FIG. 10 comprises at the proximal end a free second pivot element 1340 projecting towards the second side plate 113, which is configured to engage with the second latching recess 1132 of the second side plate 113, where it also engages with another pivot support 135 (see. Fig. 3). Thus, the latch 13 is pivotally mounted and substantially perpendicular to the bottom plate 111 on the chassis 11. A second latch tab 1341 protruding from the latch 13 towards the second side plate 113 serves as an upper stop for the Bowden cable crank 15 (see below).

The side portions 133, 134 have a bend zone 1333, 1343.

On the latch 13, adjacent to the protruding latch portion 131, on its sides, there are through holes 1310, 1311, into which the tabs of the flat sliding elements 1312 enter from below with latches that snap on the upper side (see also Fig. 2). These flat sliding elements 1312 can be made, for example, from polyoxymethylene, in particular from POM-500 AV (for example, Delrin® 500 AF) or polyethylene, in particular from ultra-high molecular weight high density polyethylene (for example, GUR®).

Between the first and third side plates 112, 114 adjacent to each other are first and second casings 1610, 1620, which are attached to the bottom plate 111 by countersunk head screw connections 163 and in which the first gear motor 161 or the second gear motor 162 ( see Fig. 3). Gear motors 161, 162 are electric motors with a suitable gear ratio, for example, from 1:10 to 1: 10000. The power of the motors is, for example, from 1 W to 200 W, preferably 5 W.

The first and second axles 1611, 1621 of the first and second gear motors 161, 162 run parallel to each other and protrude from the inner space of the chassis 11 perpendicular to the bottom plate 111. On the portions of the axles 1611, 1621 protruding outward from the bottom plate 111 through the recesses 1111, the first and the second pivot arms 171, 172 are non-rotatable about them (see FIG. 2).

The pivot arms 171, 172 are two-arm arms with a first arm 1711 or 1721 and an opposite second arm 1712 or 1722 (see FIG. 3). The pivot arms 171, 172 are attached by cylinder head screws 173 to the corresponding engine shaft 1611, 1621. The fastening screws 173 pass through the respective pivot arm 171, 172 perpendicular to the respective motor axis 1611, 1621.

Bolted to the bottom plate 111 for each pivot arm 171, 172 are outwardly projecting cylindrical damping stops 1110 which serve as pivot stops for the respective first lever arm 1711 or 1721. The two damping stops 1110 are positioned so that the pivot arm 171, 172 can pivot from the first horizontal end position shown in FIG. 2, in the vertical direction V, for example from 1 ° to 5 °, as well as a turn, for example, from 91 ° to 95 °. This allows the pivot arms 171, 172 to be vertically positioned at the dead center.

The second arm 1712, 1722 of the lever has a rounded end surface for engaging the corresponding slide plate 1312, i. protrudes from the horizontal in the direction of rotation of the lever. Thus, the pivot arm 171, 172 is made in the form of an eccentric element, therefore, in the first stable position, the pivot arm 171, 172 is at the upper shock-absorbing stop 1110, i.e. in the horizontal position shown in FIG. 2, flat sliding elements 1312 in the lower closed position of the latch 13 adjoin the end surface of the second arm 1712, 1722 of the lever, pressed by the action of the tension spring 14. When the first arm 1712, 1722 of the pivot arm 171 or 172 is pivoted slightly more than 90 °, to the opposite the lower shock-absorbing stop 1110 into the second position having a vertical position, the second arm 1712 or 1722 of the lever passing along the flat sliding element 1312, due to its eccentric circular shape, gradually pushes the flat sliding element 1312 and, thus, the latch 13 from the axis 1611, 1621 of the engine 161 or 162, so that the latch 13 pivots in the pivot bearings 135, and the latch portion 131 moves from the locking position (indicated by the solid line 13 in FIG. 12) up to the unlocking position, releasing the carriages 40 (indicated by the dashed line 13 in FIG. 12) ... FIG. 12, the latch 13 is shown in two positions with respect to the hook elements 80 of the carriage 40.

In this case, the rotation of the pivot arm 171, 172 to a vertical position slightly greater than 90 ° leads to the fact that the pivot arm 171, 172 moves in the second position to the indicated dead center position. Thus, the gear motor 161 or 162 is neither in the first position (the horizontally oriented pivot arm 171, 172 is at the upper shock-absorbing stop 1110, and the latch 13 - on the upper edge of the chassis 11 or indirectly on the shock-absorbing stop 1110), nor in the second position ( the vertically oriented pivot arm 171, 172 in the dead center position on the lower cushion stop 1110) does not need to consume energy to maintain its position, which is energy efficient and technically reliable.

In addition, as seen in the drawings, the pivot arms 171, 172 can be skeletal to save material. The pivot arms 171, 172 can be die-cast zinc, for example.

To delimit the interior of the U-shaped chassis 11 from the rear, a main panel 18 is provided, which is located between the first and second side plates 112, 113 parallel to the bottom plate 111 of the chassis 11. The panel 18 is shown in FIG. 3, 7 and 8 and by means of screw connections 183 is attached to casings 1610, 1620 or motors 161, 162. The axles 1611, 1621 of the motors pass through the panel 18 and protrude from the outside of the panel. On these protruding parts, drive levers 181, 182 are mounted, which are attached to the corresponding axis 1611, 1621 by means of a retaining ring 184. The first and second drive levers 181, 182 are single-armed, while at the free end of the arm there is a permanent magnet 185, the magnetic field of which directed towards panel 18.

Since the drive arms 181, 182, like the pivot arms 171, 172, are mounted on the respective motor axles 1611, 1621 without the possibility of pivoting about the axes, these drive arms 181, 182 have the same pivot range, i.e. can also be rotated slightly more than 90 (between the shock-absorbing stops 1110. In the end positions of the drive levers 181, 182, an external Hall sensor 186 is installed between the permanent magnet 185 and the panel 18. Accordingly, for each drive lever 181, 182 in the end positions, two external Hall sensors 186, which are arranged in a circle. The drawings also show the conductive paths 187 for the operation of the Hall sensors 186. To provide warning of the approach of the end stop, two internal Hall sensors 188 are installed between the external Hall sensors 186, which are fed to the electronic unit device 10 carriage locking signal about the approach of the lever 181, 182 to its end positions.

In addition, panel 18 houses other electronic components such as microcontrollers 189, printed connector 1890, and the like.

An energy storage device 21, 22 can be connected via a printed connector 1840. As energy storage 21, 22, two independent, i.e. mutually redundant capacitors 21, 22 with sufficient capacities from 5'000 to 100'000 microfarads, which are installed on a separate panel 200 (see Fig. 11). The energy storage 21, 22 supplies energy, which can be supplied to the gear motors 161, 162, and the amount of which is sufficient to perform up to three unlocking or locking movements in a single charge of energy. In this case, a certain capacitor 21, 22 is attached to each gear motor 161, 162.

The 1890 printed connector provides power and communication with the main control unit.

As an option for manual release, a Bowden cable 15 with a crank release lever 151, which is described with reference to FIGS. 4-6. The release lever 151 is pivotally mounted on a pivot shaft 152 under the second latch tab 1341 of the latch 13 on the third bottom plate 111 of the chassis 11. The first crank arm 1511 projects downwardly and contains two slots 153 through which in the lower part of the chassis run parallel to each other a friend two cables 154, 155 Bowden cables. In the slots 153, adjusting screws 156 are provided, with which you can adjust the tension of the Bowden cable 15. Bowden cable cables 154, 155 pass through the undercuts provided in the first and third recesses 1121, 1141 of the first or third side plates 112 or 114. Cable cables 154, 155 pass through hex nuts 157 screwed to the third side plate 113 of the chassis, while between the nuts 157 close to the crank arm and the first crank arm 1511 are fitted with one or two pressure springs 158 that move the release arm 151 to its original position (closed position) (see Fig. 4). The second crank arm 1512 projects upward from the pivot 152 and forms a contact portion 1513 that is in contact with the bottom surface of the second latch tab 1341 (FIGS. 5, 6).

When the Bowden cable 15 is activated, the pressure springs 158 are compressed, and the release lever 151 is rotated about the pivot axis 152 from the initial position (Fig. 6) to the actuation position (Fig. 5), while the contact portion 1513 presses upward on the second latch tab 1341, in as a result, the latch 13, overcoming the force of the tension spring 14, is rotated from the locking position to the unlocking position.

An additional microswitch unit 19 for monitoring the release lever 151 is attached to the bottom plate 111 by a screw connection 193 and a base plate 194, and wires 195 are provided to control the component 19.

FIG. 13 and 14 show another embodiment of a rod stopper with two sliding rods 6, which run along the main closing edges 20, 30 in the respective flaps 2, 3. The flaps 2, 3 are mounted with the possibility of shear on two carriages 40 in the profile guide 4 and shown in the closed position. The carriage locking device 10 is located in the center of the profile 4 and is connected in the upper part 61 with the sliding rods 6, for example by means of a bayonet lock, so that the movement of the locking element 13 from the locking position according to FIG. 14 to the release position according to FIG. 13 causes vertical movement of the rods 6 upward. In the locking position shown in FIG. 14, the system 1 is locked because the free ends 62 of the slide bars 6 are engaged with the recesses 600 provided in the floor 60, forming a positive-locking connection to provide locking at several points. Such floor recesses 600 can be appropriately reinforced. If unlocked, the latch 13 moves upward, pulling the slide bars 6 vertically upward from the floor recesses 600, see FIG. 13. At the same time, the mechanical connection between the latch 13 and the sliding rods 6 is released, so that the flaps 2, 3 can be turned or moved. In this case, the sliding rod 6 in the closed position prevents the rotation of the inner rotary flaps and the sliding of the outer sliding flaps 2, 3.

Additionally or alternatively, the slide bars 6 can also lock along the main closing edges 20, 30. FIG. 15 and 16 show a stopper with one sliding bar 6 and a central pivot bolt 63, which is mounted on the main closing edge 30.

FIG. 15, the latch 13 is shown in a free position, with the sliding rods 6 raised upwards, and the hook element 63 connected to the sliding rod 6 does not engage with the counterpart located on the other main closing edge, thus, the door is not locked.

FIG. 16, the latch 13 is shown in the closed position, with the slide bar 6 moving the hook element 63 into engagement with the other main closing edge 20, and thus the door is locked. This requires only one sliding bar 6. However, it is also possible to provide several hook elements 63 on the main closing edge 20, 30 and / or several sliding bars 6. In addition, pivot bars 63 can be provided on both closing edges 20, 30, which are adapted to engage with the respective opposite closing edge 30, 20. In this case, it can also be realized to engage with the floor by means of one or more sliding bar 6, as described above.

Accordingly, along the main closing edges 20, 30, a simple and economical locking at several points can be realized, which can reach the floor 60. This does not require the use of any mortise locks, which makes it possible, for example, to increase the glazing area of the door leaf, since there is no need to install a mortise lock.

The sliding flaps can also be locked along the auxiliary closing edges 21, 31 (see Fig. 1) with locking elements using one or more sliding rods 6.

Instead of the door system 1, the present invention can also be used for a window system, the sash being then a sash and not a door sash.

It should be noted that the stopping device for the sliding door system 1 can be implemented without the carriage 40, in which case the second stopping element is directly or indirectly attached to the leaf 2, 3. The second stopping element can also be, for example, a sliding bar 6, which runs along the main closing edge of the door and in the locking position enters the recess provided in the floor, while during unlocking the said sliding bar comes out of the recess in the floor and the door is unlocked.
