Description

The invention relates to a drive with a drive device and a separating device with such a drive, which is guided in a running rail and connected to at least one separating element, such as a sliding door.

For separating or designing rooms or for closing room or window openings separating elements, such as sliding doors are often used, which are attached to slidable along a running rail drives and optionally rotatably mounted. Such sliding doors are made for example of transparent glass, wood or metal.

From [1], EP 1 916 370 A1 , A generic drive is known, which is used for driving a linear and displaceable in curves, optionally rotatable and parkable separating element. This drive, which is guided by means of two wheels on a running surface of a rail, has a driven by an electric motor and a gear drive shaft with a gear which engages in a connected to the rail timing belt and rolls on this and thereby the drive along the running rail shifts. The separating element is preferably rotatably held by the drive by means of a load shaft, so that displacements are also possible along a curve.

In 2], WO 97/49885 It is shown that for the displacement of sliding doors into a parking space two-part guide rails are used, which have a branch in the station area, from which a straight and a curved rail element are continued. The sliding doors are each suspended from two guided in the track rails drives, one of which moves into the straight and the other in the curved rail element. The Sliding doors are rotated 90 ° and stacked on a wall, for example. Therefore, a special rail system is required for the rotation of the sliding doors, which may need to be adapted individually to the local conditions.

From [3], Product catalog of HAWA AG, "Architectural hardware for sliding shutters", 2006, page 36 , a fitting for Faltschiebeladen even or odd number of wings is known, which are installed, for example, on a window front or the outside of a balcony. The wing elements of the folding packages are rotatably connected to each other by means of hinges. Such a folding package can be pushed laterally against a wall or used freestanding as a visual or windbreak. The displacement, opening or folding of the folding package is done without additional rail element by manual action. In this case, the wing elements are usually rotated at unequal speed, so that, depending on the manual action, each result in irregular folding operations.

The present invention is therefore an object of the invention to provide a drive with a drive device and a separation device with such a drive, by means of the separating elements are more advantageous movable.

The drive should occupy only a small amount of space, so that this, as already known drives, can be mounted displaceably within a running rail or takes up less space.

Dividers connected to the drive should advantageously be transferable to desired positions, for example into a stacked arrangement.

The drive should also be universal for any separation devices, in particular for individual separation elements, Sliding pile walls and Faltschiebewände be used to be moved more advantageous.

This object is achieved with a drive and a separating device which have the features specified in claims 1 and 9, respectively. Advantageous embodiments of the invention are specified in further claims.

The drive provided for a separating device has a drive body serving to hold a separating element, which holds at least two running wheels movable on a running rail, and a drive device formed from at least one electric motor and a gear, which is coupled to a first drive element, by means of which a force directly or indirectly transferable to the track and the drive is drivable.

According to the invention, the drive device is coupled to at least one second drive element, by means of which the rotatably held separating element can be driven, in particular is rotatable.

The drive device therefore allows the drive on the one hand of the drive within the track rail and on the other hand of the separating element with only one motor and with only one gear. The drive according to the invention therefore makes it possible to displace at least one separating element optionally along a running rail. At the same time, the drive allows the separator to be selectively rotated. Since only one motor is used, the drive can be fully integrated into the track and does not take up more space than known drives.

By means of the inventive drive separating elements can be selectively moved and rotated without a manual intervention or a corresponding rail system would be required. A separator can thus optionally as Sliding door and / or used as a swing door. For example, according to the invention equipped separating elements can be extended from a parking space and joined together to form a partition without a complex rail system is needed. Furthermore, the separating elements can be stacked at any position, for example in the parking space or in the middle region of the running rail. For this purpose, a first separating element is moved to a parking position and rotated there in a position perpendicular to the running rail. The rotation process can be started already when approaching the parking position, so that several separating elements can approach each other quickly.

Particularly advantageously, the inventive drive for folding sliding walls can be used in which a plurality of separating elements are hinged together. So that the operations for opening and closing the folding sliding wall run optimally, the drive devices of the individual drives are programmed or controlled accordingly. Possible is a wireless or a wired transmission of control signals, for example via the power supply lines, as in [4], EP 1 657 393 A1 is described. In this case, optical, electrical and mechanical sensors and switches are used, the signals of which are taken into account by an associated control program, so that, for example, collisions are avoided.

Drives according to the invention are also particularly advantageously usable for separating elements which are provided with solar cells. These dividers can be moved along a track and rotated to follow the course of the sun and always to achieve an optimal angle of incidence. The electrical energy emitted by solar cells is preferably stored in an accumulator which is provided within the drive according to the invention. The Arrangement of a rechargeable battery is also particularly advantageous in conventional drives.

As the transmission, a planetary gear is preferably used, which has a coupled to the electric motor input shaft, an output shaft and a coupled to the input shaft and the output shaft gear housing. According to the invention, the input shaft, the output shaft and the transmission housing are rotatably mounted in the drive, wherein one of the drive elements is coupled to the transmission housing and the other of the drive elements to the output shaft. In principle, it is also possible to couple one of said drive elements or a further drive element to the input shaft. This is especially true if another gear is integrated within the engine.

The basic structure of a planetary gear is e.g. shown in http://de.wikipedia.org/wiki/Planetengetriebe and described. Planetary gears typically have a planet carrier rotatable about an axis of rotation, with at least one toothed planet gear arranged on the planet carrier, which is coupled, on the one hand, with a centrally arranged, toothed sun gear and, on the other hand, with a ring gear, which has an internal toothing. The planetary gears revolve around the sun gear and roll on the internal teeth of the ring gear. If the ring gear remains stationary, takes place with each revolution of the disc carrier a certain number of revolutions of the planet gears and thus a corresponding number of revolutions of the sun gear. When the output shaft is held stationary with the sun gear, however, the ring gear rotates.

According to the invention, the planetary gear is installed and stored so that all parts remain rotatably mounted. By the drive motor and the input shaft, therefore, the ring gear and the output shaft are driven, each with a preferably toothed first and second drive element are provided.

In this case, the input shaft or the output shaft with the planetary gears or the carrier thereof or be coupled to the sun gear. The ring gear is fixedly connected to the housing of the planetary gear, which thus rotates at the same angular velocity as the ring gear. The axes of rotation of the input shaft, the output shaft and the gear housing preferably extend coaxially with each other, which is why the drive device can be constructed extremely compact.

The drive device is preferably installed in the drive in such a way that the axes of rotation of the output shaft and the gear housing are aligned perpendicular to the main axis of the track rail and preferably perpendicular or parallel to the axes of rotation of the wheels. The drive device can therefore be horizontally, longitudinally or transversely, or standing integrated into the drive. The drive elements can cause the displacement and rotation of the separating element or the drive of the drive in various ways directly or indirectly.

Preferably, two bus bars are provided within the track, which are scanned by electrical contacts, which are provided laterally or on top of the drive. The drive device can also be powered by a built-in drive accumulator.

In a further preferred embodiment, a mounting shaft serving to hold a separating element is rotatably mounted in the drive body and arranged parallel to the output shaft and coupled via a preferably toothed connecting element with the second drive element. The storage of the separating element is therefore decoupled from the drive device, which only via the second drive element causes the rotation of the separating element. However, it is also possible to connect the separating element directly, rotatable or fixed, with the output shaft.

If the separating element is firmly connected to the output shaft, this is rotated together with the output shaft. If the separating element is rotatably connected to the output shaft, the drive of the separating element via other gears.

However, the use of a separate mounting shaft, by means of which the separating element is held, has the advantage that it can be connected to a toothed wheel or a segment of a toothed wheel, which is driven by the second drive element with the desired transmission ratio. This makes it possible to rotate even heavier separating elements.

The partition elements of a sliding stack wall can be moved into a parking space and rotated together or sequentially. It is particularly advantageous that the separating elements can be driven so far against each other after a relatively small rotation until the drives connect to each other. The opening of a Faltschiebewand is therefore no longer limited by the previously common retraction speed in a parking space, but can be done with a multiple higher speed. Particularly advantageous solution according to the invention can be used in systems with glass separating elements, in which a minimum rotation is sufficient to drive separating elements against each other. The mutually driven separating elements form a stack, which can then be rotated as far as the total until the stack is parallel to a wall.

The provided for the displacement of the separating element first drive element can drive the drive in various ways. Preferably, the first drive element with a coupling belt extending in parallel along the track and coupled thereto. The first drive element in this case is a toothed wheel which engages in the toothed belt held stationary in the running rail and thereby drives the drive.

Alternatively, the first drive member may also be directly or indirectly coupled to the wheels of the drive, whereby the drive is moved by the drive of the wheels.

The drive preferably has a local control unit that controls the drive motor. In order for the desired drive element to be moved in each case, preferably at least one locking unit is provided which can lock the output shaft or the gearbox housing. If the separating element is displaced, but not to be rotated, the second drive element, which is preferably connected to the output shaft, is locked. If, however, no displacement and only one rotation of the separating element is desired, it is preferably locked to the transmission housing connected first drive element. In the first case (locking of the second drive element) the separating element is functionally a sliding element, e.g. a sliding door. In the second case (locking of the first driving member), the separating member is functionally a rotary member, e.g. a revolving door. By appropriately controlling the at least one locking unit, the functions of the separating element can therefore be changed as desired, whereby the combination of both functions is possible.

When using the drives according to the invention in a folding sliding wall, preferably every second of the hingedly interconnected separating elements is connected at the front to a drive according to the invention. The drive speed of each drive is preferably set such that the opening angles between each change two of the separating elements at least approximately the same speed when opening and closing the folding sliding wall. If, for example, a folding sliding wall with four separating elements and two drives according to the invention is provided, the drive motor of the first drive, which covers twice the distance, rotates twice as fast as the drive motor of the second drive. The drives are driven by the first drive elements at a corresponding speed in the track, while the second drive elements cause the rotation of the separating elements.

The separating elements can be connected to each other by conventional hinge devices, as known from [3] and in FIG. 6 are shown. In these known hinge devices, both separating elements are rotated about the same axis, so that the adjoining the axis of rotation end faces of the separating elements in the manner of a pair of pliers and close. For example, if a toddler gets into the range of rotation of these end faces, significant injuries can result.

In a preferred embodiment of the invention, therefore, two of the separating elements of the folding sliding wall are connected to each other via a hinge device which form a provided for the first separating element first axis of rotation and provided for the second separating element second axis of rotation, which are spaced apart and parallel to each other. The complete mutually rotating the end faces of the separating elements is therefore avoided. In order to completely eliminate the risk of injury and to avoid disturbing gaps between the individual separating elements, preferably hollow round profile segments are provided on the oppositely directed end faces of the separating elements, said hollow round profile segments being at least one of the opening and closing edges of the folding sliding wall approximately constant distance from each other against each other are rotatable. A dangerous forceps movement is thus avoided.

In a preferred embodiment of the inventive hinge device preferably C-shaped mounting profiles are provided on the underside and top sides of each two mounting blocks of a first and second hinge unit are mounted, which are rotatably supported by a connecting plate coaxial with the associated axis of rotation , Preferably, the mounting blocks have intermeshing pinion segments, which ensures that both separating elements are rotated by the same amount. Particularly advantageously, the mounting blocks can be mounted by means of sliding blocks, which are inserted and tightened in the C-shaped mounting profiles.

The separating elements are preferably held on their upper side, preferably near an end face, so that a rotation takes place about an end face which always remains below the running rail. On the underside, the separating element can be guided in an example embedded in the ground guide rail. In preferred embodiments, the separating element is held at the bottom and at the top by a drive according to the invention and moved by a drive device. The drives are moved synchronously in the rails, so that they always remain vertically aligned. For this purpose, the local control units of the drives preferably communicate with each other. Alternatively, only two local drives are used for two drives connected to a separator. Communication lines and / or control lines are preferably laid on the end faces of the separating elements, preferably in the hollow profile segments. By using two drives according to the invention, separating elements which are generally made of any materials, such as Glass, metal or wood, can be made easier to turn.

The FIGS. 1 . 2 . 3 and 4 show an inventive drive 1 in different spatial representations. FIG. 1 shows the drive 1 sideways from below. FIG. 2 shows the drive 1 sideways from above. FIG. 3 shows a cross section through the drive 1 at the height of the drive device 10. In FIG. 4 the drive 1 is connected to a separating element 6A and guided in a running rail 5.

The drive 1 has a drive body 102, on each of which two wheels 21 and one guide wheel 22 are rotatably mounted on both sides. In the drive body 102, a mounting shaft 16 is also rotatably mounted in a bearing block 1021 (see FIG. 2 ), which can be connected to a separating element 6 (see FIG. 4 ). On the front side, a buffer element 24 is inserted into the drive body 102, which cushion the impact of the drive 1 on another body, an end stop or another drive 1.

As described so far, the drive 1 with the drive body 102, the wheels 21, the guide wheels 22 and the mounting shaft 16 in the in FIG. 4 shown running rail 5 are used and moved manually.

According to the invention, the drive 1 additionally has a drive device 10 by means of which a first drive element 13, namely a toothed wheel, is driven, which can engage in a toothed belt 130 installed in the running rail 5 and drive the drive 1 along the running rail 5, as shown in FIG the Figures 3 . 4 and 5 is shown.

Further, the drive device 10 drives a second drive element 14, also a gear, which in a toothed connection element 15, one with the mounting shaft 16th connected segment of a gear, engages and this can rotate about the axis of rotation xm of the mounting shaft 16.

For mounting the drive device 10, the drive 1 is provided with an additional module 101 which is rigidly connected to the drive body 102 via connecting elements 103. In the additional module 103, in which the drive device 10 is held on one side, the elements of the electrical system, including the programmable by means of a switch bank 81 control unit 8 and sliding contacts 18A, 18B are provided by means of which in the track rail 5 routed busbars 180A, 180B are scanned (please refer FIG. 4 ).

The drive device 10, which in FIG. 5 in an exploded view and in FIG. 3 installed in the drive 1, comprises an electric motor, for example, type "EC 32 FLAT" MAXON MOTOR AG whose drive shaft is coupled to a differential gear or planetary gear, for example, the type "GP 22 A" from the same manufacturer.

In FIG. 2 Furthermore, a second drive device 10 'is shown, which can also be integrated into the drive 1. If the second drive device 10 'is integrated, then the first drive device 10 can be equipped with only one drive element 13 which, for example, serves to engage the toothed belt 130 and the drive of the drive 1. The drive shaft of the second drive device 10 'can be coupled directly to the mounting shaft 16. Like this in FIG. 2 is shown, the two drive devices 10, 10 'are mounted side by side with preferably parallel to each other aligned drive shafts.

From the Figures 3 and 5 It can be seen that the electric motor 11, a connection cable 112 and a motor body 117th in which the drive shaft 111 is rotatably mounted and which is mounted in the additional module 101 by means of mounting screws 110. The drive shaft 111, which simultaneously forms the input shaft of the planetary gear 12, is rotatably mounted in the housing head 122 of the planetary gear 12 by means of first and second bearing elements 121, 123 and connected to a gear 124. The gear 124 is, for example, a sun gear which drives planet gears (not shown) rotatably mounted on a planetary carrier connected to the output shaft 126 rotatably supported in the planetary gear 12. By the planet gears, a ring gear is further driven, which is connected to the housing 125 of the planetary gear 12 and rotates in synchronism therewith. The output shaft 126 of the planetary gear 12 is rotatably supported by a third bearing member 127 which is fixed in the drive body 102 by means of fixing screws 25. The planetary gear 12 is therefore including the input shaft 111, the output shaft 126 and the gear housing 125 rotatable about a common drive axis ax, in this embodiment of the drive 1 perpendicular to the main axis of the track rail 5 and perpendicular to the axis of rotation of the wheels 1 and 21 mx parallel to the axis of rotation the mounting shaft 16 is aligned. In FIG. 3 clearly seen that with the first drive member 13 (shown in section) connected gear housing 125 of the planetary gear 12 is held only by the input shaft 111 and the output shaft 126, which in turn are rotatably mounted.

It is understood that also different drive devices can be used with other engines and differently constructed differential and planetary gears, which can be operated with any movement, including kinematic reversal. For example, the output shaft may be connected to a sun gear. Furthermore, multi-stage transmissions, eg with several planet carriers and sun gears, used. All that is required is that two torques on the transmission used can be transmitted to a first and a second drive element 13, 14.

In the embodiment shown, the first drive element 13, a gear meshing with the toothed belt 130, is connected to the transmission housing 125 by means of mounting screws 131. The second drive element 14 is connected to the output shaft 126 of the planetary gear 12 and coupled to a toothed connection element 15, which is a quarter-segment of a gear in the embodiment shown. The connecting element 15 is connected by means of a mounting strip 152 inserted into a receiver 151 with a separating element 6A (see FIGS FIGS. 1 and 4 ) connected or connectable. The diameters of the second drive member 14 and the connecting member 15 are selected so that the installed partition member 6A can be driven with high torque. The segmental section of the connecting element 15 is selected according to the desired angle of rotation. In many applications, a rotation angle of 90 °, which makes it possible to align the installed separating element 6 perpendicular to the axis of the running rail 5, for example, to park parallel to a wall. If necessary, however, the connecting element 15 can also be a complete gear.

In FIG. 5 Furthermore, the control unit 8 of the drive 1 is shown with the preferably provided switch bank 81, the switches are set according to the desired speed of the drive 1 (see also the Figures 8a, 8b and 8c ). The operating current is the drive 1 preferably from an external power supply unit 800 via the in FIG. 4 shown busbars 180A, 180B and the sliding contacts 18A, 18B supplied. Via the busbars 180A, 180B, between the local control unit 8 in the drive 1 and a central control unit 80 further data, operating data, Status signals, as well as control signals are transmitted. This makes it possible for each drive 1, which is connected to a folding sliding wall 60 or only with a separating element 6, to control individually. This is particularly advantageous in larger plants, in department stores or in façade buildings, in which on the basis of the separating elements 6, a weather protection, sun protection, solar energy production or aesthetic effects are to be achieved. The dividing elements 6 can each be moved in the configuration desired by the architect. As mentioned, the dividing elements 6 can also be moved and turned as required, depending on the weather and the solar radiation. Particularly advantageously, the drive devices 10 of the separating elements 6 can also be fed by solar cells 800S which are mounted on the separating elements 6 or are installed stationary, for example on the facade of a building.

Particularly in the case of separating elements 6, whose drives 1 are fed by solar cells 800S, an accumulator 82, possibly a capacitor with a high capacity, is preferably integrated in the drive 1, preferably in the additional module 101. This ensures the autonomous operation of the drive 1. Also possible is a mixed operation in which the external power supply unit 800 is loaded only when required, for example to initialize the separating elements 6 or to drive to a position provided for the energy absorption.

Systems with a plurality of separators 6 equipped with solar cells 800S can be used for power generation and recovery in the public power grid. For this purpose, a current control unit 8000 is used, which converts a direct current into an alternating current, which can be impressed into the public alternating current network AC. Devices of this type are for example, from [6], DE 196 38 880 C1 known. Particularly in the case of façade installations, it is possible to generate a considerable proportion of the energy required in a building through the partition elements 6 or solar cells 800S installed on the facades.

In a preferred embodiment, the busbars 180A, 180B are used to transmit the current delivered by the mobile or stationary solar cells 800S. Preferably, a direct current generated by the solar cells 800S or an alternating current derived therefrom is transmitted via the busbars 180A, 180B to the current regulating unit 8000 or to other consumers, optionally to drive devices. If solar cells 800S (or solar panel) are permanently installed on a facade of a building, then provided for the separating elements 6 busbars 180A, 180B at the same time as a busbar for recording and transfer of solar energy for feeding back into the AC mains and / or for the drive the separating elements 6 used. In this case, it is possible to completely separate the recovery and recovery of solar energy, which takes place via the busbars 180A, 180B, from the power supply of the separator elements 6. Alternatively, the solar energy can be switched on each time the required demand can be met.

For example, there is a transfer of solar energy in time periods in which the dividing elements 6 are not driven. It is also possible that a direct current from the solar cells in the bus bars 180A, 180B is impressed, while for the drive of the separating elements 6 of the power supply unit 800, an alternating voltage to the bus bars 180A, 180B is applied, which superimposes the output from the solar cell 800S DC voltage becomes.

Preferably, however, both of the power supply unit 800, as well as of the solar cell 800S DC voltages preferably of the same size are applied to the busbars 180A, 180B. By the local and central control unit 8 and 80 is checked in the sequence, whether the solar energy is sufficient for the supply of the separating elements 6.

In this case, one or more threshold values can be monitored by the local and central control unit 8 or 80. If, for example, the voltage delivered by the mobile and / or stationary solar cells 800S exceeds a first threshold value, the power supply unit 800 is switched off and the system is operated only with solar energy. If the voltage delivered by the mobile or stationary solar cells 800S exceeds a second threshold value, the power control unit 8000 additionally feeds energy back into the AC network AC. With regard to the connection and disconnection of the power supply unit 8000 and the solar cell 800S, a communication between the central and the local control units 8, 80 is preferably provided. If solar cells 800S are installed stationary, they are preferably provided with a local control unit 8 ', for example a single-chip processor. For the connection of stationary solar cells 800S, the busbars 180A, 180B preferably have plugged terminals 18 '(in FIG FIG. 5 shown schematically), which are led out of the running rail 5 or accessible therein.

The transmission of control signals can be realized in any way. For example, control signals are transmitted by radio, optically or by radio waves, or wired via electrical lines, in particular the busbars 180A, 180B, as described in [4]. In this case, signals can be transmitted, for example, by the time division multiplexing or the frequency division multiplexing method or by connecting and disconnecting the DC voltage.

The transmission of solar power over the bus bars 180A, 180B is particularly advantageous in systems in which the drive 1 according to the invention is used, but can also be used to advantage in the use of other drives and drive systems. As mentioned, the solar power can be fed into an AC grid and / or provided for driving further drives or dividing elements, e.g. Due to unfavorable sun exposure insufficient solar energy.

in FIG. 5 it is further shown that by means of the control unit 8 via control lines 182, two preferably provided locking units 83, 84 are controllable, by means of which the first or the second drive element 13, 14 can be blocked or inhibited. By actuating the first locking unit 83, the first drive element 13 can be locked, which serves for the displacement of the drive 1 within the running rail 5. In this case, only the second drive element 14 is actuated, which can rotate the held separator 6. By actuating the second locking unit 84, the second drive element 14 can be locked, after which the held separating element 6 only moved, but not rotated. By means of the local or central control unit 8, 80, the separating element 6 can therefore be moved and / or rotated as desired. The two locking units 83, 84 can be designed, for example, as two-part brakes which comprise the gear housing 125 or the output shaft 126 or the second drive element 14 loosely and are tightened if necessary by means of an actuator. In order to avoid mechanical wear, the drive motor 11 can also be stopped when changing the operating states of the locking units 83, 84. In this case, it is possible that the gear housing 125 or the second drive element 14 is also held in a form-fitting manner.

In FIG. 4 the drive 1 is inserted into the U-shaped rail 5, which has a central piece 52 and two side pieces 51, which are each provided with guide and mounting ribs 53, 54, 55, which protrude into the rail cross-section. At the center piece 52, two first ribs 53 are provided, which each include with the associated side piece 51 a space in which one of the busbars 180A, 180B is mounted. Between the two first ribs 53, two guide wheels 23, which are preferably provided on the upper side of the drive 1 and / or on the additional module 101, are guided (see FIG FIG. 2 ), by which the drive 1 is held in a vertical position. By the further, provided on the side pieces 51 of the guide rail 5 ribs 54 and 55, a space for receiving the toothed belt 130 is formed, which is installed only on one of the side pieces 51. The lowermost ribs 55 form a downwardly directed L-profile, within which the guide wheels 22 provided laterally on the drive 1 are guided. By the lateral and upper guide wheels 22, 23 is therefore ensured that the wheels 21 can track accurately and in the correct position roll on the foot elements 511, which are provided at the lower ends of the side pieces 51 and directed against each other. The stabilization of the drive 1 in the running rail 5 by arranging corresponding running and guiding elements 22, 23 is preferably provided as a function of the load of the separating element and in dependence on the use of a running and / or guiding device on the opposite side of the separating element 6. In principle, a drive can be provided which has an impeller 21 on only one side. Often drives are used, which have two wheels 21 on one side, so that branches are used within a rail system. Drives 1 according to the invention can therefore also be used for complex rail systems.

The busbars 180A, 180B can alternatively also be arranged on the side pieces 51 of the track rail 5. It is also possible to arrange the toothed belt 130 on the center piece 52 of the running rail 5. This can be expedient if the drive axle ax of the drive devices 10 is aligned parallel to the axis of rotation 1 x of the wheels 21. In this case, it is also possible to couple the input shaft 111, the output shaft 126 or the rotatably mounted gear housing 125 via gears or toothed belt with one of the wheels 21 and drive this. In this case, the mounting of a toothed belt 130 is unnecessary, which may be advantageous in particular in facade construction.

in FIG. 4 is also shown schematically that the inventive drive 1 is particularly advantageous for the drive of Faltschiebewänden 60 can be used, the elements 6A, 6B, ... to be moved along the slide rail 5 and rotated to open the Faltschiebewand 60 and close.

For this purpose, the individual separating elements 6A, 6B,... Can be provided with hinge devices 7 ', as described in [3], page 36, and below in FIG FIG. 6 are shown. In FIG. 6 is a not provided with a drive devices, known drive 1 'shown, which is guided in a known track 5', which is mounted in a recess 911, a ceiling 91. On the underside of the separating elements 6A, 6B, a guide device 1 "is provided with a roller which is guided within a recess 92 provided in the bottom 92 and thereby absorbs the torque caused by the separating elements 6A, 6B, so that the upper drive 1 'only The drive 1 'and the guide device 1''are connected to the known hinge devices 7' via a mounting shaft 16 'In these known hinge devices, both separating elements 6A, 6B are rotated about the same axis, so that the end faces of the separating elements 6A, 6B adjoining the axis of rotation open and close in the manner of a pair of pliers. The resulting problems have been described in the beginning.

According to the invention, a hinge device 7 is used, which in FIG. 7 is shown as an example. This hinge device 7 forms a first rotation axis x1 provided for the first separation element 6A and a second rotation axis x2 provided for the second separation element 6B, which are spaced apart in the region of the mutually facing end sides of the separation elements 6 and run parallel to one another. The complete mutually rotating the end faces of the separating elements 6A, 6B is therefore avoided. In order to completely eliminate the risk of injury and to avoid disruptive gaps between the individual separating elements 6A, 6B, hollow round profile segments 74A, 74B are provided on the mutually facing end faces of the separating elements 6A, 6B, which at an approximately constant distance from each other during opening and closing of the folding sliding wall to be turned around. It is therefore no longer possible for a person to reach, for example, by hand between the end faces of the separating elements 6A, 6B and be injured. The surge between the round profile segments 74A, 74B can also be completed by elastic sealing elements.

In the preferred embodiment of the hinge device 7 of FIG. 7 are provided on the mutually facing end faces of the separating elements 6A, 6B C-shaped mounting profiles 75A, 75B, which extend over the entire length of the end faces. Two mounting blocks 72A, 72B are mounted on the bottom and top surfaces of the C-profiles 75A, 75B by means of sliding blocks 721A, 721B, which are inserted into the C-profiles 75A, 75B and tightened. This type of installation is particularly easy and can be done in a few simple steps be done. The mounting blocks 72A, 72B are rotatably mounted by means of mounting screws 731 to a connecting plate 73 at a mutual distance selected such that pinion segments 71A, 71B connected to the mounting blocks 72A, 72B can engage with each other. The pinion segments 71A, 71B cause a rotation of the first mounting block 72A to result in a same rotation of the second mounting block 72B. This measure ensures a uniform opening and closing of the folding sliding wall 60. The connecting plate 73 also has a stop 732, which limits the deflection of the hinge 7 and causes the separating elements 6 can be folded only in one direction.

The Figures 8a, 8b and 8c show inventive folding sliding walls 60 with two, four or six separating elements 6A, 6B; 6C, 6D; 6E, 6F connected to one another by means of hinge devices 7 according to the invention and by means of one, two or three drives 1X according to the invention; 1Y; 1Z are held and driven, which are movable along a running rail 5 between a first and a second wall 94.95. For each folding sliding wall 60, starting with the first separating element 6A, which is provided on the front side with a drive 1X, each further second separating element 6C or 6E is likewise provided on the front side with a further drive 1Y according to the invention; 1Z provided.

Shown is also the switch bank 81X; 81Y; 81Z of each drive 1X; 1Y; 1Z, by means of which the travel speeds are individually adjustable. It can be seen that in the switch bank 81X of the first drive 1X, both switches are set to "1", so the drive 1X drives at maximum speed when operated. In FIG. 8b the switches are set so that the second drive 1Y drives only half as fast as the first drive 1X, which has to travel twice that way. In FIG. 8C are the Drive speeds from drive to drive 1X; 1Y; 1Z reduced by one third according to the distances to be covered.

In the embodiments of Figures 8a, 8b and 8c in each case the last separating element 6B or 6D or 6F of the folding sliding wall 60 is hinged to the first wall 94. In various applications, however, it could be advantageous if the entire folding sliding wall 60 can be moved in the folded or at least partially open state. For this purpose, preferably also the last separating element 6B, 6D; or 6F provided with a drive 1. As a result, the folding sliding wall 60 can be moved as a closed stack. Furthermore, it is preferably provided that the drives 1X; 1Y; 1Z are also individually controlled, so that a folding package can be moved to a specific location and opened there.

As mentioned, two drive devices 10, 10 'can also be integrated into the drive 1, of which the first serves for driving the drive 1 within the running rail 5 and the second for driving or rotating the separating element 6. In this case, both drive devices 10, 10 'are controlled accordingly by the control unit 8, for which reason the locking devices 83 and 84 can be dispensed with.
