Description

The invention relates to a platform for attachment to a facade. Furthermore, the invention relates to a facade-side receiving device and a system comprising such a facade and such a facade-side receiving device.

In order to carry out work, in particular construction, repair or maintenance work, on a building facade, scaffolding is usually used, which is erected on the facade. The disadvantage is that erecting such scaffolding is labor- and time-intensive and, moreover, cannot be implemented on every facade.

Platforms are known from the prior art which can be installed on a building facade instead of scaffolding.

For example disclosed DE 102 44 099 A1 a facade rescue system with a self-propelled rescue platform. The rescue platform is transportable and can drive on high-rise building facades with its own drive on the guide rails attached there. The rescue platform has a chassis that engages in the guide rails with driven wheel sets.

Furthermore is off DE 43 36 142 A1 a facade construction and a working lift are known. A façade construction designed as a curtain wall has a lattice-like support structure made up of horizontal and vertical T-beams.

KR 20120088244 discloses a robotic system for maintaining an exterior wall of a building. The robotic system includes a variety of work modules and one or more work stations. The working modules are moved in a horizontal direction along the building wall.

The object of the invention is to provide a platform for a building facade that can be installed on a building facade with little effort and can be flexibly moved on a building facade.

• - wenigstens einen ersten Tragarm und einen zweiten Tragarm,
• - ein an dem ersten Tragarm und an dem zweiten Tragarm befestigtes Plattformelement,
• - eine Aufhängungs- und Verfahreinrichtung zum Aufhängen und Verfahren des ersten und des zweiten Tragarms in einer fassadenseitigen Aufnahmevorrichtung, wobei die Aufhängungs- und Verfahreinrichtung derart ausgebildet ist, dass der erste und der zweite Tragarm in horizontaler und vertikaler Richtung in der fassadenseitigen Aufnahmevorrichtung bewegbar sind.

The object according to the invention is achieved by having a platform for attachment to a facade

• - at least a first support arm and a second support arm,
• - a platform element fastened to the first support arm and to the second support arm,
• - A suspension and displacement device for suspending and displacing the first and the second support arm in a receiving device on the facade, the suspension and displacement device being designed in such a way that the first and the second support arm can be moved in the horizontal and vertical direction in the receiving device on the facade.

The platform according to the invention can be easily hung on a receiving device on the facade and moved on it, so that advantageously every area of the facade can be reached to carry out different work on the facade or also in the case of a fire brigade or rescue operation in the building.

The platform element is held by the first and the second support arm, the latter in turn being attached to the facade or a receiving device on the facade via the suspension and displacement device. In the state arranged on the facade or on the receiving device on the facade, the first support arm and the second support arm are preferably arranged vertically.

The suspension and displacement device preferably has at least one first suspension and displacement component on the first support arm and at least one second suspension and displacement component on the second support arm. The platform or the platform element thus has at least two fastening points on the facade or the receiving device on the facade.

The suspension and displacement component is advantageously designed in such a way that it assumes both the function of, in particular indirect, suspension or attachment of the platform to the facade and the function of the displacement, in particular the horizontal and vertical displacement, of the platform. The platform element is preferably connected to the suspension and displacement device via a cross-connection element, as will be explained in detail below.

The suspension and displacement device preferably has a third suspension and displacement component on the first support arm and a fourth suspension and displacement component on the second support arm. According to this embodiment, the platform as a whole preferably has four attachment points on the facade or the receiving device on the facade. The number of suspension and movement components of each support arm can preferably be chosen depending on the configuration, in particular depending on the size and load class, of the platform.

The platform has at least two support arms. Preferably, the platform can also have further support arms, for example a third or fourth support arm, each of which also has at least one suspension and displacement device. In particular, all support arms of the platform are preferably configured identically, in particular with regard to their respective suspension and movement components or suspension and movement components.

The terms "horizontal" and "vertical" refer to the condition of the platform attached to the facade. In other words, the support arms are configured to move in a first direction and to move in a second direction, the first direction being perpendicular to the second direction. In particular, the support arms for moving the platform on the facade are designed to move simultaneously at the same speed in the same direction in order to move the platform as a whole.

Preferably, the support arms are also movable in a third direction, the third direction being perpendicular to each of the first and second directions. The third direction is a direction away from the facade. As a result, the support arms can advantageously be moved not only on a flat facade, but also around a building projection. For this purpose, either the support arms or the receiving device on the facade are preferably provided with a corresponding displacement mechanism, by means of which the receiving device on the facade or the support arms can be displaced in the third direction.

Preferably, the first support arm and the second support arm are each telescopic, so that the first and the second support arm can be retracted and extended such that a distance between two suspension and movement components arranged on a support arm can be adjusted. For this purpose, the first support arm and the second support arm preferably each have a first support arm movement unit and a second support arm movement unit, by means of which a length of the first and second support arm can be changed in such a way that the distance between two suspension and movement components arranged on a support arm can be changed. On each of the support arms, one of the suspension and displacement components is preferably attached to a first end section of the support arm and the respective other suspension and displacement component is attached to the other end section of the support arm.

In order that the support arms can be extended and retracted, the support arms are preferably designed in multiple parts and in particular have a plurality of, preferably at least two, elongate sections which can be slid into one another telescopically.

The suspension and movement components of the support arms preferably have a spindle and a worm gear cooperating with the spindle. The spindle and the worm gear are preferably arranged on different sections of the support arm so that the sections are moved relative to one another during operation of the worm gear so that the support arms are extended and retracted telescopically. As an alternative to the spindle system described above, other types of drive are also conceivable, for example a hydraulic drive.

Extending and retracting the support arms or varying the distance between the suspension and traversing components arranged on the support arms serves to bring the platform spatially into line with the suspension points on the facade or the facade-side mounting device, so that the platform as a whole can be attached to the facade. In particular, the platform can be adapted in this way to receiving devices on the facade that are designed differently, depending on the facade, or to differently arranged suspension points on the facade.

For example, a receiving device on the facade can comprise vertical rails arranged in parallel, into which the support arms are hung by means of the suspension and movement components, as will be described in more detail below. Depending on the design of the facade, such rails can be attached to the facade at different distances from one another. Due to the possibility of being able to adjust the distance between the suspension and movement components of two support arms, the platform can be used advantageously for various rail systems of this type. As a result, the platform can advantageously be used flexibly.

The receiving device on the facade can preferably be a system comprising horizontal and vertical rails which are arranged in a grid-like manner. At the crossing points of the vertical and horizontal rails, the platform can switch between a horizontal and a vertical travel mode. To do this, all suspension and movement components of the support arms must be centered over these crossing points so that the change of direction can take place.

Preferably, each of the suspension and traversing components has a position sensing com component up. The position detection component is used to detect the position of the platform on the facade or on the facade-side recording device. In particular, the position detection component is used to detect a position on the facade-side recording device at which a change in the direction of travel, in particular between the horizontal and vertical directions of travel, is possible.

The position detection component preferably has a sensor which is designed to detect a predetermined position on the facade-side recording device, in particular by means of induction.

The platform preferably has a cross-connection element, the cross-connection element connecting the first and second support arms to one another. The suspension and traversing components of the first support arm and the suspension and traversing components of the second support arm are arranged or fastened to the cross-connection element at a distance corresponding to the horizontal track gauge. The cross-connection element is held on the outer wall by the first bracket and the second bracket. The platform element is arranged on the cross-connection element or is carried by the cross-connection element.

The distances between the suspension and movement components of the support arms, i.e. the distance between the suspension and movement components of one support arm and the distance between the suspension and movement components of different support arms, is preferably adjustable in order to adapt the platform to different facades or buildings. adjust facade-side recording devices.

If the receiving element on the facade is designed as a grid-like rail, as described above, the suspension and movement components can be moved horizontally and vertically in such a way that they are centered over the crossing points of the horizontal and vertical rails, so that the direction of movement can be changed.

The platform preferably has a position detection device. This makes it possible to determine the position of the platform on the facade or the facade-side recording device.

Preferably, each of the suspension and traversing components includes a position sensing component. As a result, the respective position of the individual suspension and movement components can be determined relative to one another and/or relative to the facade or the facade-side receiving device. In particular, it can be determined by means of the position detection components of the individual suspension and movement components whether the platform is in a suitable position for switching between the horizontal and vertical movement modes.

If the receiving element on the facade is configured as a grid-like rail as described above, the position detection components can preferably be used to detect whether the individual suspension and movement components are aligned centrally over the crossing points of the rails.

To detect a position of the platform relative to the facade or the facade-side receiving device, a positioning element is preferably arranged on the facade or the facade-side receiving device, which can be detected by the individual position detection components.

According to a preferred embodiment, the positioning element is magnetic, for example in the form of a magnetic pin.

The position detection components are preferably designed to detect the magnetic positioning element, in particular the magnetic pin, in particular by means of induction, as a result of which a signal is generated which indicates the position of the respective position detection components.

Alternatively or additionally, the position can be detected by means of RFID (radio frequency identification).

Each of the suspension and movement components preferably has a first subassembly for carrying out a horizontal movement of the platform and a second assembly for carrying out a vertical movement of the platform. In the horizontal movement mode, the platform is preferably fastened, preferably exclusively, by means of the respective first subassembly of each of the suspension and movement components to the facade or the facade-side receiving device. In the vertical movement mode, the platform is preferably fastened, preferably exclusively, by means of the respective second subassembly of each of the suspension and movement components to the facade or the facade-side receiving device.

Preferably, the first subassembly and the second subassembly each have at least one, preferably two, drive element or drive elements, in particular a gear or gears, for Ver drive up the first and the second support arm. A corresponding receiving device, for example a pinion structure or a gear rack, for engaging the drive element or drive elements, in particular the gear wheels, of the respective assembly is preferably arranged on the facade or the facade-side receiving device. Preferably, the first subassembly and the second subassembly each have two drive elements, in particular gear wheels, in order to enable stable movement of the platform. The two drive elements of an assembly are preferably arranged one behind the other, viewed in the direction of travel.

Preferably, the first subassembly and the second subassembly each have at least one holding and guiding element for holding the platform on the receiving device on the facade and for changing between a horizontal movement mode and a vertical movement mode of the platform. The holding and guiding element is designed in such a way that it holds the platform on the facade or the receiving device on the facade and at the same time allows the platform to move in the respective travel direction. For the first assembly, the holding and guiding element associated with this enables horizontal movement, while for the second assembly, the holding and guiding element associated with it enables vertical movement of the platform.

The holding and guiding element preferably has at least one undercut for engagement with a projection on the receiving device on the facade.

The holding and guiding element is preferably essentially T-shaped or mushroom-shaped when viewed in cross-section. Due to the T-shape or mushroom shape, the holding and guiding element has two undercuts, which can each engage in corresponding projections in the receiving device on the facade. The holding and guiding element is preferably of essentially flat design. This means that, in particular in the mushroom-shaped design of the holding and guiding element, the two undercuts formed by the mushroom shape are formed in one plane.

Alternatively, the holding and guiding element can comprise two holding jaws. These holding jaws are preferably designed according to the principle of two brake shoes, with the holding jaws being provided or coated with a sliding coating, in particular Teflon, on their contact surface with the receiving device on the facade.

Furthermore, the holding and guiding element can be a linear bearing having rollers which engage in the undercuts of the receiving device on the facade.

The holding and guiding element is preferably designed to be rotatable, in particular rotatable by 90°, for changing between a holding position and a release position.

As an alternative to the T-shaped holding and guiding element, two L-shaped holding and guiding jaws, analogous to the braking device, can preferably also be pivoted into a holding position of the load rail and can also be designed as plain or linear bearings to withstand high tensile and compressive forces to be able to record.

The at least one drive element and the holding and guiding element can preferably be moved in and out of the assembly in order to switch between an operating state and a rest state of an assembly. In the operating state, the at least one drive element and the holding and guiding element are preferably extended, while the driving element and the holding and guiding element are retracted in the idle state. One of the first or the second assembly is preferably in the operating state at a time while the respective other assembly is in the idle state in order not to impede the assembly that is in the operating state.

The holding and guiding element is preferably in the release position in the rest state and in the holding position in the operating state. As described above, the holding and guiding element is preferably of flat design with two undercuts located in one plane. Due to the flat shape, the holding and guiding element can be inserted into the receiving device on the facade side and by turning the holding and guiding element, the undercuts can be brought into engagement with projections on the receiving device on the facade side. For example, the receiving device on the facade can include C-rails, into whose elongated rail opening the holding and guiding element is inserted with the flat sides correspondingly oriented parallel to the elongated rail opening and then rotated by 90° so that the undercuts of the holding and guiding element fit into the C- can reach behind the rail.

In the idle state, the drive element and the holding and guiding element are preferably partially or completely within a housing of the respective assembly. In the operating state, the drive element and the holding and guiding element are preferably extended in such a way that they can be brought into engagement with the facade-side receiving device.

The modules are preferably retracted and extended simultaneously in all suspension and movement components. In particular, the first assemblies, by means of which the platform can be moved horizontally, of all suspension and movement components are moved in and out essentially simultaneously. The moving in and out takes place with a small time delay, so that at all times at least one module is in the holding position. The same applies to the second assembly of all suspension and traversing components. Furthermore, the first assemblies of all suspension and movement components are preferably moved out and at the same time the second assemblies of all suspension and movement components are moved in in order to switch to the horizontal movement mode. In order to switch to the vertical travel mode, starting from the vertical travel mode, the first assemblies of all suspension and travel components are moved in, while the second assemblies of all suspension and travel components are moved out.

The first and the second subassembly of the suspension and movement components are preferably each of essentially identical design. The first subassembly and the second subassembly are preferably arranged at an angle of 90° to one another.

Each of the suspension and movement components preferably has a drive device, in particular a drive motor, actuators for setting the individual components, sensors and/or a control unit.

The platform preferably also has a central control and operating unit, by means of which the suspension and movement components are controlled in a coordinated manner.

The platform preferably has a stop device, the stop device preferably being designed in such a way that it can engage in a non-positive manner in the receiving device on the facade, in particular in load rails of the receiving device on the facade. The stop device preferably engages in a manner similar to that of the holding and guiding element in the receiving device on the facade, in particular in a projection of the receiving device on the facade.

The stop device preferably has a square mushroom shape, the square shape. The contour of the stop device preferably corresponds to the undercut of the c-shaped load rails.

In addition, the stop device preferably also has a holding and guiding function on the suspension and movement components. The stop device is preferably rotatably mounted, for example for the purpose of mounting and aligning a support arm. However, the stop device is preferably not extendable.

The platform preferably has a braking device comprising two brake shoes, each with a braking surface. Each assembly group preferably has at least one braking device for the vertical and the horizontal movement. In the embodiment of the holding and guiding elements as C-rails, the brake shoes pivoted into the undercut of the C-shaped load rails rest with their braking surface on the C-rail during traversing operation and mutually support one another in the middle. The pivoting takes place in particular by means of a movable piston which exerts a force on the two brake shoes. The piston can in particular be driven hydraulically. A tensile force acting on the braking device causes a self-reinforcing compressive force or braking force on the braking surface. In the pivoted-in state, lying against the undercut, the stop device offers security against the platform falling down should the holding and guiding element tear off.

The braking process can preferably be initiated by an acceleration sensor on the platform, which detects an acceleration of the platform relative to the facade. Alternatively, the braking process can preferably be initiated manually, particularly in the event of a power failure. If a braking process, in particular independently of the engine brake, can be initiated, e.g. B. by the acceleration sensor, pressure is preferably exerted on the brake shoes by means of a piston and a braking effect on the platform is achieved by frictional engagement in the groove of the load rail.

The platform element is preferably designed to be movable relative to the first and the second support arm. As a result, a working height of the platform element can advantageously be varied without having to move the platform as a whole.

The length of the platform element can preferably be changed parallel to the facade. In particular, the platform element is constructed in several parts with a central element and two side elements that can be moved out of the central element. As a result, the working area on the platform element can advantageously be enlarged.

The platform element is preferably laterally displaceable relative to the cross-connection element. The displacement of the platform element is preferably carried out by means of two roller-guided traverses, which are positively and non-positively connected to the platform element, driven by a servomotor located on the platform element with a further pinion structure, which engages in a toothed rack arranged on the cross-connection element and thus enables lateral displacement.

The platform element preferably has a peripheral railing.

The object according to the invention is also achieved by a receiving device on the facade, which is designed to receive a platform with the features described above.

The receiving device on the facade can preferably already be attached to the facade of a building when it is erected and subsequently installed on an already existing building.

The receiving device on the facade preferably comprises at least one holding and guiding device for receiving the holding and guiding element on the platform. The platform can preferably be hung in the receiving device on the facade, in particular by means of the holding and guiding elements of the individual assemblies, and can be moved in this on the facade.

The at least one holding and guiding device is preferably a load rail, in particular a C-rail.

The holding and guiding device preferably comprises at least one horizontally arranged load rail and at least one vertically arranged load rail.

The load rails are preferably of identical design.

The load rails preferably have a rail opening whose width is 5 mm to 15 mm, particularly preferably 7 mm to 13 mm, very particularly preferably 9 mm to 11 mm.

The holding and guiding device preferably comprises a multiplicity of horizontally arranged load rails and a multiplicity of vertically arranged load rails, the horizontal and the vertical load rails being arranged in the form of a grid. At least two vertical and at least two horizontal load rails are preferably provided. More than two, for example 3, 4, 5 each up to, for example, 20 or more load rails can preferably be provided, the number of load rails depending on the design of the building. The number of horizontal load rails can preferably be equal to the number of vertical load rails. Alternatively, the number of horizontal load rails and the number of vertical load rails can differ, for example more horizontal load rails than vertical load rails can be provided or vice versa. The number of respective load rails is preferably adapted to the design of the respective facade.

The vertical load rails are preferably arranged at a predetermined distance from one another, so that a horizontal track width is set between the vertical load rails. The horizontal track width between the individual vertical load rails can be set identically for all vertical load rails or varying vertical track widths can be set between the different vertical load rails. This applies analogously to the horizontal load rails, with a vertical track width being adjustable here. The vertical track gauge preferably corresponds to a floor height of the building.

The holding and guiding device, in particular the lattice-like load rail structure, is preferably attached to the facade of the building and preferably extends over all areas of the facade that should be accessible by means of the platform. The holding and guiding device preferably extends essentially over the entire facade.

Each of the holding and guiding devices preferably comprises a receiving device, in particular a pinion structure, for receiving a drive element of the platform. If the receiving device is designed as a pinion structure, the pinions extend along the direction of movement of the platform. If the holding and guiding devices comprise load rails, the pinion structure is introduced into the load rails and extends along a longitudinal extension of the load rails. In the embodiment of the load rails as a C-rail, the pinion structure preferably runs within the C-shaped groove.

The receiving device on the facade is preferably designed to receive panel elements. The panel elements are preferably cladding elements and/or insulating elements, for example HPL (high pressure laminate) panels or Trespa panels. In particular, the plate elements are attached to the load rails.

The receiving device on the facade preferably has panel elements, preferably cladding elements and/or insulating elements, very particularly preferably HPL (high pressure laminate) panels and/or Trespa panels.

The plate elements are preferably fastened to the holding and guiding devices, with the holding and guiding devices being designed as C-rails and the plate elements being fastened in the C-rail by means of a, in particular resilient, holding element.

The plate elements are preferably suspended and positioned in the C-shaped groove of the holding and guiding devices by means of resilient holders. The Trespa panels are preferably rear-ventilated compared to the insulation panels, which are fastened or glued to the wall using dowels and holders.

The plate elements are preferably arranged at a constant distance from one another of 5 mm to 15 mm, particularly preferably 7 mm to 13 mm, very particularly preferably 9 mm to 11 mm. This distance is preferably identical to the rail opening of the load rails, so that the facade has a uniform appearance. Due to this concept with small and uniform gap dimensions, it is not immediately apparent what options are available for use, e.g. B. rescue operations, transport, repairs, facade cleaning, etc., are given.

The platform preferably has an energy recovery device for storing potential energy when the platform is shut down. The energy recovery device is preferably a generator.

The object according to the invention is also achieved by a system comprising a platform and comprising a receiving device on the facade, each with the features described above.

According to a preferred embodiment of the system, several, in particular at least two, vertical and horizontal load rails are provided. The platform preferably has at least two suspension and movement components per support arm, the vertical and horizontal distances of the suspension and movement components being adjustable as described above in order to be able to be adapted to the vertical and horizontal track widths of the facade-side recording device. In this way, the platform can preferably move in the different horizontal and vertical tracks of the receiving device on the facade and thus advantageously reach different areas of the facade, so that cleaning and/or repair work or rescue operations can be carried out there from the platform.

• In der Steuerung des Plattformelements wird dieses hinsichtlich einer eingespeicherten Höhenposition in eine Nullposition gebracht, da das Plattformelement an einem unteren Ende der Aufnahmevorrichtung installiert wird. Das drehbare pilzförmige Halte- und Führungselement der oberen Aufhängungs- und Verfahrkomponenten der beiden Tragarme wird an einem unteren Ende oder Freimachung einer vertikalen Lastschiene eingeführt. Die Zahnräder sind zu diesem Zweck in der Aufhängungs- und Verfahrkomponente eingefahren, ebenso das Bremselement der zugehörigen Bremseinrichtung. Durch Hochschieben der oberen Aufhängungs- und Verfahrkomponenten in den vertikalen Lastschienen schwenken sich die Tragarme in eine vertikale Lage. Nun wird jeweils das drehbare pilzförmige Halte- und Führungselement der unteren Aufhängungs- und Verfahrkomponenten in die vertikale Lastschiene eingeführt und in eine Nullposition gebracht. Durch Betätigung eines stromführenden Schalters an den Tragarmen wird zunächst das pilzförmige Halte- und Führungselement der jeweiligen Aufhängungs- und Verfahrkomponenten innerhalb der vertikalen Lastschiene kraftschlüssig aktiviert, d.h. um 90° gedreht, und in Position gehalten. Gleichzeitig werden Zahnräder zweiter Baugruppe, welche das vertikale Verfahren der Plattform ermöglicht, in die vertikale Lastschiene eingefahren mittels eines elektromechanischen Antriebes oder dergleichen.

The attachment of the platform to a facade-side receiving device already installed on the facade is preferably carried out as follows:

• In the control of the platform element, this is brought into a zero position with regard to a stored height position, since the platform element is installed at a lower end of the receiving device. The rotatable mushroom-shaped holding and guiding element of the upper suspension and traversing components of the two support arms is inserted at a lower end or clearance of a vertical load rail. For this purpose, the gear wheels are run into the suspension and travel components, as is the braking element of the associated braking device. By pushing up the upper suspension and traversing components in the vertical load rails, the support arms swivel into a vertical position. Now the rotatable mushroom-shaped holding and guiding element of the lower suspension and traversing components is inserted into the vertical load rail and brought into a zero position. By actuating a current-carrying switch on the support arms, the mushroom-shaped holding and guiding element of the respective suspension and traversing components within the vertical load rail is frictionally activated, ie rotated by 90° and held in position. At the same time, gear wheels of the second assembly group, which enables the platform to be moved vertically, are moved into the vertical load rail by means of an electromechanical drive or the like.

The holding element is then locked and the braking element, in particular brake shoes, of the braking device are pivoted into the groove of the C-rail and brought into a holding position.

Each suspension and movement component preferably includes an energy store, in particular a rechargeable battery, for performing the above-mentioned control functions.

When both support arms are installed in the load rails, the cross-connection element accommodating the platform element is hung and secured on the support arms and electrical plug connections are made to the suspension and traversing components.

After that, two roller-guided traverses are preferably placed on the longitudinal beam and the platform is mounted on this in a force-fitting and form-fitting manner and a drive energy store, in particular a drive battery, is arranged on the platform and electrically connected, and the protective grille of the platform is attached. The platform on the facade can be moved to the desired position using a control panel, a remote control or a program control.

The system preferably comprises a fastening device comprising two fastening jaws, which are designed to be brought into positive and non-positive engagement with the receiving device on the facade.

The fastening device preferably has an eccentric, by means of which the fastening jaws can be held in position during engagement in the receiving device on the facade, the eccentric having a keyway, a key for locking the eccentric being arranged in the keyway.

Preferably, the fastening device also has a spring-loaded lever for fixing the fastening jaws during engagement in the receiving device on the facade.

According to a further preferred embodiment, the support arms are designed to set a distance between the support arms and the suspension and movement component. An adjustment of a distance is necessary in the case of non-planar facades, for example if they have protruding balconies, in order to adjust the distance between the support arms and the suspension and traversing component according to the protruding components. Four extension arms are preferably provided for this purpose, which are connected in a positive and non-positive manner to the suspension and movement components on the one hand and to the support arms on the other hand.

The cantilevers are preferably designed in such a way that they can be extended and retracted to adjust the distance between the suspension and traversing components and the support arms. This can in particular be done telescopically, for example hydraulically, or by a cantilever arm with a fixed length having a cantilever spindle and a worm gear of the cantilever, each of which is connected to a support arm and is driven by a servomotor. The movement of the worm gear varies the distance between the support arm and the outer wall. Furthermore, a backdrop for guiding the support arm is provided.

The invention is explained in more detail below using exemplary embodiments.
