Description

The The invention relates to a sliding door for one automatic and / or manual operation with a movable door leaf.

It There are different sliding doors in the market, whether straight or curved Form available for various applications can be used. These known sliding doors need for their Structure and the drive in the upper area a large space. About that In addition, it is difficult in tight spaces, such sliding doors also easy to assemble and maintain. This conditioned that such sliding doors especially could not be used in confined spaces. Because the sliding doors on the market are Ropes or timing belt driven, which in addition to a large space also a certain vulnerability for wear parts with brings. In the belt or rope drives is beyond for the Drive also a tensioning device available. such Clamping devices become with decreasing tension of the drive means readjusted. In addition to high frictional forces cause such Drives contribute to high wear the rotating or moving Tei len of the drive and thus a only short life. About that In addition, the energy used is consumed mainly for overcoming frictional resistance. The known sliding doors are about roles or the like on the door leaf above suspended and run in an appropriate profile. At the bottom, the door leaf is sideways passed through a rail or the like. The drive is either manually or driven by a motor or by pneumatic cylinders. In a fault case can such doors in a manual operation only with an immense force or not done at all become.

The The object of the invention is to provide a sliding door, the for various applications, for example in the mobile sector as well as in the immobile area, can be used.

there must be such a sliding door be so easy to install that they take up little space can also be quickly assembled and disassembled. Another requirement is that such sliding doors operated both automatically can be as well as manually. Furthermore, such a sliding door should also be designed for the disabled.

The The object of the invention is achieved by the characterizing features claim 1 solved in conjunction with the generic features.

The dependent claims form advantageous developments of the invention.

When solution becomes a simple, efficient and energy efficient engine of a sliding door proposed which in dual, d. H. at the same time manual and automatically driven usage can be used. For example, if the drive energy fails, the sliding door can be opened manually fully functional actuated become. About that It is also possible that in case of a missed power failure, the sliding door still manually operated can be. Only by a conscious operation, for example one Tasters, a drive unit is activated, which is an automatic Operation of the sliding door guaranteed.

A such sliding door, which may have a straight or curved course, in particular in confined spaces be used. This can also be in the mobile sector, for example rail-bound vehicles, be an execution. Especially in one such a cramped design it is necessary that the person using the room is not in Panic gets And the security has that such a sliding door also manually their full functionality reserves.

Of the Door leaf runs preferably on two adjustable rollers, which are embedded in the bottom of the door and be guided on or on a rail in the ground area. Such a guide rail can be embedded in the ground or with a low height on the ground Floor to be mounted. So it is possible that this rail also no Obstacle for example for wheelchairs offers.

The upper guide the sliding door over two side brushes on the door leaf, which are kept in a profile, for example. These brushes are supported preferably from a U-profile, as the upper guide profile is trained. This U-profile is over the entire doorway on the ceiling or above Attachments mounted on a wall. As already stated, the Drive unit is a compact unit in the middle of the whole Running path mounted on the upper guide profile is.

The modular drive unit consists essentially of the modules of a drive wheel, an adjustable counter-pressure roller, a pressing unit and a measuring unit. All modules are mounted on a mounting plate in mutual relation to each other and thus form a module that can be used unchanged or with small variations for a variety of drives. The drive wheel is for example a single drive wheel, which is driven by an electric geared motor. The gear motor with the drive wheel is mounted on a rocker and can be pressed by a pneumatic or electrical unit against a metallic tread in the upper part of the door leaf. The aforementioned abutment to the drive wheel forms the counter-pressure roller, which is located on the opposite side of the drive wheel of the metallic tread. Thus, it is possible that by means of this counter-pressure roller, a horizontal alignment of the door is done and a clean run is ensured in the upper guide.

The Measuring device may for example consist of a roll, the is equipped as a measuring roller with appropriate sensor technology. It has proven to be advantageous that such Displacement measuring roller sprung executed becomes. In the execution The running speed will thus determine the exact position of the door leaf and forward to microprocessor control for processing.

Further can for the End positions "open" and "closed" sensors be present as fixed reference points at both ends of the upper leadership for example, are attached.

At the Door is about that In addition, a locking unit exists, both manually and as well can be operated automatically.

One Another central component is the microprocessor control / regulation. This is preferably also present in the region of the drive module, to meet so easy maintenance or accessibility requirements to become. This microprocessor control / regulation can be for all conceivable Functions programmed according to the requirements and via parameters be set. about a status display shows the current status. That's the way it is also possible, in the appearance of disturbances to make them visible with the status display. Furthermore, the Microprocessor control / regulation separate entrances for external Signals on.

So such a sliding door according to the invention combines the advantages of a manual, as well as a powered door leaf, the On the one hand the comfort of a driven door and on the other hand the safety during operation in manual mode. Here comes beyond yet a resource conservation through low material use as well efficient energy consumption and a longer durability of the wear parts added. This is because of the wearing parts the drive unit to a necessary Minimum are reduced. Such a drive unit is a module interchangeable and also consists of individual modules, so for different applications, assemblies can be used unchanged. So For example, the drive unit for different door widths and even for right or left opening Door without change be used.

The Field of application of such a sliding door, for example, a toilet cabin finish or Shower stall or the like in both the immobile and be in the mobile sector. Especially for use in rail vehicles offers this type of sliding door size Advantages. Thus, the drive is always energized in the idle state and thus is not in contact with the door leaf. This facilitates one dual operation in that in this constellation the door is always can be moved freely manually. However, it is also the same Arrangement possible, such a door automatically to operate, especially for disabled people a big one Relief is.

Just through the duality this sliding door is it is possible that the use of powered sliding door in disabled people brings relief. But also for non-disabled older people the opportunity offers, such a door in a conventional manner, namely manually. Due to this discrepancy between the disabled persons and not handicapped people is the trend in public buildings to manual doors further trained. This was also because of that the cramped installation situation no fully automatic door installed could, but what with the present sliding door according to the invention readily possible is.

So is also a quasi-mixed operation possible, in which the sliding door manually opened but has not been closed by the person. By the intelligent microprocessor control / regulation, it is possible that it is at an adjustable period the door after this period automatically moved to the closed end position. Consequently Just by the sliding door according to the invention the advantages of a manual as well as a powered door through the comfort of a powered door and safety in the Operation ensured in manual function.

Further Advantages, features and applications of the invention result from the following description in connection with in The embodiment illustrated in the drawings.

The invention will be described in more detail below with reference to the embodiment shown in the drawing. In the description, in In the claims, the abstract and the drawings, the terms and associated reference numerals used in the list of reference numerals recited below are used. Show it:

1 a schematic diagram of a sliding door in plan view, in a closed position and non-active position of a drive unit;

2 as 3 but in an open position;

3 a schematic diagram of a sliding door in which the closed door is driven by a drive unit;

4 as 3 but in the open position.

In 1 becomes one with the reference sign 1 designated schematic representation of a sliding door in plan view reproduced. In this embodiment, it is a curved sliding door, but the invention can also be applied to an embodiment of a straight sliding door.

Inside a lower guide rail 5 is by means not shown roles a door 2 moved on the marked circular path. It is also an upper guide rail 4 available, so that the door 2 has a clean leadership. On the right side of the door leaf 2 is a fitting 3 shown, which allows a closure 9 to bring from a closed position to an open position. The closure 9 However, it is also designed so that it can be automatically brought via a not shown microprocessor control / regulation in a locking position and in an open position. This can be done for example by pressing a button, a sensor or the like.

A drive unit, in which in the 1 individual modules are arranged schematically consists essentially of a drive wheel 6 that with a counter-roll 8th interacts, which on a profile part - drive surface - on the door leaf 2 running up and on the door 2 is attached. The drive unit also includes a coupling unit 10 and a measuring device 7 , In the presentation of the 1 the drive unit is not active, as the door leaf 2 manually over the fitting 3 can be operated. For example, a good interaction between the drive wheel 6 , which is designed as a friction wheel, with the mating gear 8th to reach is the counter-wheel 8th and also the drive wheel 6 designed so that it is adjustable, for example via an eccentric.

The coupling unit 10 can be both pneumatic when it comes to track-bound vehicles. However, it is also possible to form these electrically. Through the coupling unit 10 becomes the drive wheel 6 against a drive surface, not shown, on the door leaf 2 in the area of the counter-wheel 8th pressed. Thus, by the rotational movement of the drive wheel 6 a movement of the door leaf 2 along the guide rails 4 and 5 be performed.

To get an exact position of the door leaf 2 Determining the entire route is the measuring device 7 available. The measuring device 7 For example, it can be a measuring roller that is sprung so as to be able to compensate for possible slippage. However, it is also possible that the measuring device consists of an incremental encoder or a sensor element measuring from another path.

In the 2 is opposite the 1 the door has been brought into the open position by manual operation. This was the door 2 by manual force between the lower guide rail 5 and the upper guide rail 4 postponed. In this position can behind the door 2 For example, the door can be entered manually after entering the room 2 again in the closed position according to the 1 to be brought.

The automatic operation and thus the movement of the door leaf 2 About the drive unit is in the 3 and 4 played.

In the 3 will be the door 2 after an automatic unlocking of the closure 9 via the drive unit, namely the drive wheel 6 , which is against the door 2 and thus in connection with the mating wheel 8th is pressed between the guide rails 4 and 5 emotional. The pressing of the drive wheel 6 against the guide surface, not shown, thereby accomplishes the coupling unit 10 ,

In the 4 will be the door 2 reproduced in the open position.

For example, automatic operation may be initiated by a request of a disabled person by pressing a button on the wall or the like. At this moment, the drive unit is switched on, so that the drive wheel 6 the door leaf 2 from the closed position brings out. If the person is the room behind the door 2 on the one hand, the door can close automatically, but it is also possible that this again another button or the like is operated. The door leaf 2 closes automatically and the locking device in the form of the closure 9 also automatically locks the door leaf 2 , However, it is also possible that this another button or the like is operated so that no other person can enter the room. To leave the room, the person again actuates the button and the door leaf 2 goes into the open position. Furthermore, it is possible that before opening the door leaf for safety reasons, the unlocking of the door is actuated by another button or the like.
