Description

The invention relates to a self-supporting sliding gate with a stationary base and at least one running rail, on which a door leaf is arranged, and a drive system with an electric motor, wherein the running rail is optionally mounted indirectly on the stationary base and displaceable by the drive system relative to this and the drive system is located at and / or in the door leaf and communicates with the base, as in the closest prior art DE 94 18 079 U1 is described.

Self-supporting sliding gates are known from the prior art. In conventional designs of such sliding gates, in particular in the DE 3401 105 A1 described, there is a transmission of drive and / or braking forces with elements such as racks, belts, chains and / or ropes, these elements are in operative connection with drive motors and / or brake systems. The drive motors and / or brake systems are fixedly connected to a floor or foundation and do not move with the door leaf.

In the known self-supporting sliding doors is disadvantageous that in these a high space requirement for drive systems is given. Furthermore, it is disadvantageous that a construction of such sliding gates on site is time-consuming, which leads to high assembly costs.

The object of the invention is to provide a self-supporting sliding gate of the type mentioned, in which the mentioned disadvantages are eliminated.

This object is achieved in a self-supporting sliding gate of the type mentioned, when the drive system comprises a rope, a chain, a belt or other like-acting element which is fixed in two areas of the base and pulleys in the region of ends of the door leaf of a region extends to the other region of the base and is in contact with a drive roller of the electric motor, so that the at least one running rail is displaceable relative to the base during operation of the electric motor.

In a self-supporting sliding gate according to the invention is of advantage that a space requirement is reduced overall, since at least parts of the drive system on and / or are arranged in the door leaf. In addition, it is advantageous that a sliding gate to be installed can be created with a high degree of prefabrication. The sliding door can already be equipped with the drive system during production, so that complicated work in connection with a coupling of the sliding gate with a drive system or at least parts of it can be omitted in the sequence when mounting the sliding gate at a mounting location. A displaceability of the door leaf relative to the base is achieved in that the drive system is in communication with the base. During movement of the sliding gate, parts of the drive system move together with the door leaf, wherein the drive system is preferably completely integrated in the sliding gate.

Further features, advantages and effects of a sliding gate according to the invention will become apparent from the following description of exemplary embodiments. In the drawings show:

• Fig. 1 a schematic representation of a sliding gate according to the invention;
• Fig. 2 a variant of a sliding gate in a first position;
• Fig. 3 the sliding gate according to Fig. 2 in a second position.

In Fig. 1 is an inventive sliding door 1 shown in partial cross-sectional view. The sliding gate 1 is designed as a self-supporting sliding gate 1 and therefore has on the bottom side only a base 2, which is fixedly mounted on a foundation 6. The base 2 is relatively short in comparison with a total length of the sliding gate 1 and often has a length of less than 100 cm. On the base 2 is a door leaf 4, which is mounted on a running rail 3, movable. The door leaf 4 does not necessarily have to be formed with struts, but can also be present as a full-surface body. The running rail 3 of the door leaf 4 is mounted indirectly on the base 2. For this purpose, a further running rail 7 is provided, which is slidably mounted on rotatable rollers 18 of the base 2 and substantially shorter than the running rail 3 is formed. The further running rail 7 has further rotatable rollers 19 on which the longer running rail 3 runs. If the sliding gate 1 is extended or retracted, then the further running rail 7 coupled together with the running rail 3 moves on or off, so that the running rail 3 is always supported by the further running rail 7. The further running rail 7 thus carries a part of the load of the door leaf 4 or transmits this load in In order to ensure a desired movement of the further running rail 7 relative to the running rail 3 or vice versa during insertion as well as during extension, at least one catch 20 is provided which ensures a coupling or decoupling of corresponding movements. Instead of or in addition to the rollers 18, 19 and sliding elements of any kind can be provided. The basic principle of such a sliding gate 1 is in the international application with the publication number WO 2008/006129 A1 described.

The running rail 3 is usually designed so that it covers or covers the further running rail 7 and at least parts of the base 2, so that an aesthetic appearance of the sliding gate 1 is achieved. How out Fig. 1 it can be seen, a drive system 5 is arranged on or in the door leaf 4. The drive system 5 comprises an electric motor 9. Furthermore, the drive system 5 comprises a cable 8 which is fastened in two regions 11, 12 of the base 2 and via deflection rollers 13, 14 in the region of ends 15, 16 of the door leaf 4 from a region 11 to the other region 12 of the base 2 extends and is in contact with a drive roller 17 of the electric motor 9, so that the running rail 3 is displaceable relative to the base 2 during operation of the electric motor 9. Instead of the rope 8 may also be provided a chain, a belt or other equivalent element. In contrast to the prior art, the electric motor 9 is not arranged stationary, but is moved together with the door leaf 4. This is achieved in that the intended cable 8 is connected to the base 2 in connection or is attached thereto. Thus, it is possible by operation of the drive roller 17, in contrast to the guide rollers 13, 14 and optionally further provided and shown pulleys high friction for the cable 8, the door leaf 4 to move. The proposed drive system 5 can be fully integrated in this case already in a production of the sliding gate 1 and also has a small footprint. Another advantage is that the rope 8 is guided within the running rail 3 and the other running rail 7 and therefore is not visible and protected. Due to the integrated in the door leaf 4 and generally sliding door 1 construction of the drive system 5, it is also possible to form the at least one driver 20, which is usually present as a mechanically actuated element, as an electrically controllable element on the door leaf 4.

A device for switching over operation with the electric motor 9 to manual operation can be provided on the door leaf 4, which can be implemented particularly easily, since the entire drive system 5 is located on or in the door leaf 4. Such switching or coupling and decoupling of the electric motor 9 can be done manually and z. B. be useful in a disturbance.

On the door leaf 4, one or more solar modules 10 may be arranged. The or the solar modules 10 are used for energy or power supply of the electric motor 9. The sliding door 1 can be completely prefabricated when equipped with solar modules 10. In particular, no work is required in connection with a connection of the electric motor 9 to an external power source during assembly. The solar module or modules 10 can also be connected to at least one accumulator, so that, for example, at night an energy-autonomous operation of the sliding gate 1 is possible. It is also possible to install on the door leaf 4 more elements that are operated with the energy gained, such as warning lights or flashing lights, which can make visible at night and / or in bad weather movement of the door panel 4. Instead of or the solar modules 10, other components may be provided for the recovery of energy, for. B. wind turbines.

Although not shown, the sliding door 1 on and / or in the door leaf 4 may also have a braking device and / or a device for storing potential energy. This can be beneficial if the sliding door 1 is not as in Fig. 1 horizontally but, for example, is positioned inclined downwards.

The drive system 5 is not on the in Fig. 1 illustrated embodiment variant limited. If z. B. in the door leaf 4 means for storing potential energy is provided, which stores energy in processes of the door leaf 4 of an inclined sliding gate 1 in one of the two directions of movement, this may be sufficient to return the door leaf 4 partially in the other direction. The additionally required energy for complete recycling can be provided by a motor which can not only be fixed to the ground and / or in the door leaf 4 but also in a conventional manner. Unlike the prior art, in the latter case, the motor can be made substantially smaller because some of the energy required to move the door leaf 4 is supplied by the potential energy storage means, and therefore has a small footprint.

In FIGS. 2 and 3 FIG. 3 shows a variant of a previously mentioned cantilever sliding gate 1 with a device 22 for storing potential energy, the sliding gate 1 being inclined. The drive system 5 in turn comprises a motor, in particular an electric motor 9, so that the door leaf 4 opposite the base 2, the in Fig. 2 and 3 consists of two separate carriers, is movable. In the door leaf 4, the means 22 for storing potential energy is arranged. This device 22 comprises a spring set which is connected to the drive system in the region 23 and to the door leaf 4 in the region 24. To transmit a force from the drive system 5 to the spring set as energy storage, for example, a further cable 25 may be provided. For the spring set z. B. gas springs are used. But it is also possible to use other elements, for. As weights or torsion springs. In principle, any means for storing potential energy are suitable. How out FIGS. 2 and 3 it can be seen, springs 26 are tensioned in a first position, whereas the springs 26 are relaxed in a second position. By this mechanism, the inclined sliding gate 1 when released from the first position ( Fig. 2 ) relatively easy to the second position ( Fig. 3 ), even if the sliding gate 1 has several hundred kilos of mass.

The sliding gate 1 according to Fig. 2 moreover has a manual switch, in particular a hand-operated latch 21. The manual switch or the hand pawl 21 is in operative connection with the drive system 5, so that the drive system 5 can be activated or deactivated by actuating the manual switch. For this purpose, an additional cable 27 is provided which connects the hand pawl with the motor of the drive system 5. This mechanism, which also in a sliding door 1 according to Fig. 1 Application is preferably formed so that the hand pawl 21 automatically opens the sliding gate 1 when depressing up to a first stage, usually at low speed. In this regard, a selector switch may also be provided or programmed in a controller such that opening of the sliding gate 1 is possible only up to a predetermined position. This has the advantage that the sliding gate 1 can be opened in a simple manner and can be closed again from an opposite side, for example by pulling up the handle 21 or in general operation of the manual switch, when a person wants to go through. So far, according to the prior art, separate sliding doors had to be provided in addition to a sliding door. In a second stage can be activated by the manual switch or the hand pawl 21, a decoupling of the motor or the drive system 5, for example in case of failure.

An advantage of sliding gates 1 according to the Fig. 1 to 3 Among other things, that the entire drive system 5 is disposed in each case within the sliding gate 1. This not only gives an aesthetically pleasing image of the sliding doors 1, but also leads to weather protection for the drive systems 5. This also provides new opportunities in the supply or management of electricity, especially mains electricity, if it is needed. For example, can be passed over the ropes 8 low voltage stream on the pulleys 13, 14 and tapped there. Alternatively, the internal parts of the drive system 5 can also be used for signal transmission, for example to open a sliding door 1 from the house.
