Description

MOTORIZED SHADING SYSTEM

The invention relates to the field of shading. The invention relates to a shading system according to the preamble of independent claim 1.

STATE OF THE ART

It is known that vertical awnings can be attached to the facade of buildings to achieve shading. Known shading systems are mounted on the facades, so that at least parts of the system permanently protrude from the facade, such as blind boxes and guide rails. Guide rails are necessary so that the tissue of the shade remains in position even in windy conditions. Such systems are known, for example, from EP 1'614'825 or EP 2'492'433. Modern facades, which are designed as a continuous surface, for example as glass fronts, also bring about the need for shading in the rooms located behind the façade. The glass fronts and thus also the rooms behind warm up strongly due to the sun's rays and the sun dazzles the people present in these rooms. For aesthetic reasons, shading is often dispensed with because a shading system built onto the façade strongly influences the aesthetics of the façade. Energetically, it would be useful to realize a shading, as often air conditioning systems are used to maintain a pleasant room temperature. With the CH 705 736 remedy is created. This application describes a retractable shading system. The disadvantages of said system, however, are the majority of the drives that are needed, as well as the weights that must be moved and also the not very stable fixation of the system in the state when shaded. Further, various electrical connections are moved, which introduces some susceptibility to failure, for example, due to cable breakage or unthreading from the connection.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a shading system, which can be sunk in or behind the facade of a building, in particular building. Furthermore, this shading system should be able to be operated as far as possible by a single drive, that is to say retracted and extended. The whole thing should also be achieved by a simple technical solution.

The object is solved by the features of claim 1. The dependent claims, the description and the figures contain special embodiments and developments of the invention.

The shading system includes a shaft, also called a roll, a rolling up on the shaft and flexible, planar light shield to cover a window surface, a drive motor for driving the shaft and a movable, retractable in or behind a facade guide means for lateral guidance of to be unrolled (to be processed) sunscreen.

The term "in or behind a facade" means behind the façade surface formed by the facade. The term "window" or "window surface" is to be understood in particular a glazed opening in the wall of a building, which in particular serves the supply of light, the view and / or the supply of fresh air. The window or the window surface can be designed so that it can be opened or not opened.

The shading system is characterized by the fact that it contains a flexible tension element which can be rolled up on a shaft driven by a drive motor. The guide device is operatively connected to the flexible tension element such that it can be moved out of the facade during the rolling of the tension element from the shaft by gravity, in particular swung out, and when rolling up the tension element by the tensile force of the tension element behind the facade retractable, in particular einschwenkbar. The shaft of the tension element is z. B. behind the guide device in the folded state.

The shaft for the tension element and the shaft for the surface light protection can be driven by a common drive motor. The tension element and the planar light protection can be rolled up on a common shaft. The tension element can be formed by the planar light protection itself.

The shading system may include a main box for installation in the recess of a facade. The shaft on which the tension element and / or the shaft on which the light shield is roll up bar, are mounted in the main box. The shafts are preferably fixed stationary in the main box. This means that the shafts remain stationary during winding and unwinding of the tension element or light protection and when extending and retracting the guide.

The main box may be closed by a flap, which by the extension of the guide device in an open position and when retracting the guide device is moved by gravity into a closed position. The flap is z. B. suspended from a hinge

The planar light protection can be weighted for gravity assisted rolling of the shaft preferably by means of a complaint element. The complaint element is in particular connected to the light protection. The loading element can at the same time be a holding element, via which the guide device is held during extension and retraction. The complaint element is preferably attached to the free end of the light shield. The Bcschwerelement may in particular be a downpipe. Hereinafter, for the sake of simplicity, the term "drop tube" will be used synonymously with the "complaint element".

The guide device preferably contains a retaining member which cooperates with the loading element. The retaining member is designed so that the guide device is held by the light shield during training and Einfehren on the complaint element. The guide device is retained in the not fully extended state via the retaining member of the complaint element and the associated sunscreen against the force acting on the guide device gravity. The complaint element is in this process on the retaining member.

The shading system may include a force sensor for measuring the torque on the traction drive motor and / or the light shield. This serves to detect the end position of the pivoted guide means.

The shading system may include a position limit switch for detecting a lower end position of the unrolled light shield. The Positionsendsehalter can be arranged in particular in the drive motor. The shading system preferably includes a pivoting device for pivoting out and in of the guide device. The pivoting device may in particular contain articulated pivot arms. The guide device may contain in a development of the invention, two spaced-apart lateral guide rails, which z. B. are connected to the pivot arms.

The shading system preferably also includes a mounting box. The shading system can be designed in particular as a mounting unit with a mounting box. All or individual components of the shading system are preferably housed in the mounting box. These are in particular the shafts, the drives, the light protection, the tension element, the guide device and the pivoting device, which are housed in the mounting box.

The mounting box may be formed U-shaped and contain two spaced side box parts, which receive the guide rails. Further, the mounting box includes the transverse to the two side box parts extending and the two box parts interconnecting main box, which receives the waves for the sunscreen and the traction means.

The Schwenkanne can be hinged on the one hand with the side box parts and on the other hand with the guide rails. The pivoting arms can be arranged so that the guide mechanism performs both a movement out of the facade and a downward movement during pivoting. Conversely, when pivoting in, the guide device moves towards the facade and from bottom to top. be attached and swung out. The guide rails or the Führungseinrichtimg can in particular via a parallelogram suspension on the mounting box, in particular on the side box parts, off and are pivotally mounted. The mounting box is particularly in an elongated, such. B. slot-shaped, recess or recess in the facade mounted mountable. The elongated recess in the facade may be U-shaped in particular. The elongated recess can in particular limit the window area to be shaded against the top and to the side.

The shading system is, in particular, a secondary market. The planar light protection can in particular be a textile fabric such as tissue. In the following, the term tissue is called synonymous for a flexible, planar light protection.

According to the invention, the drive of the vertical awning or of the fabric can be used to:

• first, to lower the tissue

Second, retract and extend the guide system of the shading system

• third, to open and close the flap

The shading system thus includes a fabric, a retractor mechanism for light protection with a shaft and a drive, and a guide device.

The mounting box can have side walls. The mounting box is mounted on or in the facade so that the opening of the U-shape points downwards. The main box preferably has a relatively large volume for receiving elements of the shading system. The main box is bounded at the top by the upper end of the mounting box. Go from the main box the two side, arm-shaped box parts of the U-förniigen plan away. They can each have lateral inner and lower terminations. Under the main box between the side box parts, the lower end of the mounting box is attached. The mounting box can be designed in its shape so that it has side walls along its entire floor plan.

The mounting box serves to mount the entire shading system in it and finally fix it in one part to the facade. Next, a closure of the facade parts is achieved by the mounting box or its side walls, so that rainwater can not get behind the facade, for example. Any water which has penetrated into the mounting box is led outwards via the appropriately angled terminations of the mounting box, which are designed to be inclined outwards on the underside. The assembly unit with mounting box is thus set back in the mounted and retracted state opposite the window surface to be shaded behind the building facade.

The left and right lateral completion of the mounting box or the corresponding side walls can be constructed in several parts. This assembly-technical reasons that the attachment of the mounting box on the inner facade level is easier or that the places for screwing the mounting box with the inner facade level are more accessible. The additional parts of the side walls of the left and right lateral completion of the mounting box can be attached after attachment. These additional parts can for example be plugged and fixed, for example by means of terminals or latches.

The light protection, hereinafter referred to as tissue, is fixed at one end to the roll, on which it can be rolled up and unrolled. The other end of the fabric is provided with the weighting means or with the drop tube, which is to be understood as a weight (which is pulled down by gravity) and on the other hand as an element of the guide mechanism. The roller is housed in a roller housing in which it is rotatably mounted left and right.

The roller is attached to the main body via the roller housing. The role of housing is z. B. fixed on its rear side at both lateral ends to a mounting rail. The mounting rail in turn is attached to the mounting box, that is at the rear end of the mounting box. The mounting rails continue in the mounting box in the respective side box parts.

The roller can be provided with a drive. The drive can rotate the roller in two directions using one direction to roll the fabric onto the roll and the other to unwind the fabric from the roll.

The drive is preferably installed directly in the role. The drive can be in the roller housing together with the roller. The drive can also be realized as an external element next to the role. It can be arranged both in the role of housing as well as directly next to it.

The drive is preferably an electric motor. But it is also conceivable to use other known types of drives. The drop tube is mounted vertically displaceable in the left and right guide rail. It can move up and down along the guide rail. The guide rail is part of the guide device.

The drop tube serves to stretch the tissue as it is unrolled from the roll and downwardly along the guide rails by gravity pull. The tissue is guided in each case in the left and the right guide rail to define the lateral position fix. This ensures that the wind can not cause fluttering of the lateral edges and thus noise and no displacement of the tissue. The guide rails are in cross-section z. B. configured substantially U-shaped.

The left and the right guide rail are rigidly connected together in the upper area by the outer and the inner connecting bar. The connection strip is arranged at right angles to the guide rail. The fabric is guided between the inner and the outer connection bar.

The inner and outer connection bars are shaped and arranged to ensure the entry of the tissue or vertical edges of the tissue into the guide rail.

The inner and outer connecting bars are further designed so that they serve as a retaining member for the downpipe so that the downpipe can not leave the guide rails. If the drop tube is not guided in the guide rails, the connecting bars still ensure retention and thus the function described later.

Above the guide rails is in each case the vertical extension of the guide rail, which corresponds to an extruded profile. Between the left and right upper vertical extension of the guide rail is the baffle. The baffle is in most states of the shading system in contact with the closure flap, which closes the cavity of the roll on the facade side in the retracted state of the shading system.

At the same starting point as the vertical extensions, the stop profile is attached to the guide rail. This essentially stands horizontally from the guide rails. The vertical extension and the stopper profile preferably form an angle of approximately 90 °.

The guide device may further include a stop member, via which the guide device rests in the extended or swung out state a component of the mounting box or the facade. The stop member may, for. B. a lower end wall of the main box.

The stop member can limit the further extension and lowering or pivoting of the guide device in the direction of gravity in continued unwinding of the light shield from the shaft. The stop member can serve the weight relief, so that z. B. not the entire weight of the guide device is supported by the pivoting device. The stop member may in particular be a stop plate. In the following, the term stop plate is also used synonymously with the term stop element, without this being to be understood as limiting.

The stop profiles on the left and the right side of the guide rail are preferably connected to each other via the stop plate. In special embodiments, if the stop profiles have a greater extent parallel to the connecting strips, it may be possible to dispense with the stop plate. The said guide rails, the connecting strips, the vertical extension of the guide rails, the guide plate, the stop profiles and the stop plate are rigidly connected together. In this entirety, they are referred to as a management framework. The guide frame may be part of or form the guide device. The guide means z. B. the guide frame and the associated combinations of fastening profiles with swivel arms, hereinafter also called guide rods. The shading system can also work without baffle and stop plate. In this case, the closing flap rests on the upper vertical extension of the guide rail and the entire guide frame rests only on the stop profiles. This requires a corresponding embodiment of the two elements.

The guide frame is fastened to the fastening rail via a fastening profile with guide rod and a further fastening profile. In this case, a fastening profile is attached to the guide rail and the other on the mounting rail, which in turn is mounted on the mounting box and so finally on the inner facade level. The intermediate guide rod is pivotally mounted in two fastening profiles. This structure corresponds to the said pivoting device. The fastening profiles are preferably configured identically. The mounting profiles with guide rod indicate a possible movement of the guide frame with two maximum positions. Between the two maximum positions, an angle of between 160 ° and 180 ° is preferably between 170 ° and 180 °. The effectively used angle is smaller, it is determined by different mechanical quantities and geometries in the overall system.

The combinations of fastening profiles with guide rods are preferably identical, ie they are in a position parallel to each other in every position of the overall system. The identical design entails that the guide frame shifts parallel to the initial position, in the retracted state of the shading system. The number of mounting profiles with guide rods, which are arranged per guide rail depends on various factors. These are, for example, the length and the weight of the guide rail or the ambient conditions at the place of use, such as the prevailing winds, which require a better attachment depending on. Preferably, at least two combinations, consisting of fastening profiles with guide rods, arranged, more preferably, the arrangement of two to three combinations consisting of Befestigungsprofi 1 with guide rods.

The guide rail is color-matched so that it meets the customer's wishes or that it integrates optimally into the façade. Preferably, no screen is mounted on the guide rail, resulting in a minimal height difference to the rest of the facade in the retracted state of the system.

On the guide rail, a screen may be attached, which gives the outer side of the guide device the same appearance as the facade. The aperture is not necessarily mounted over the entire outer surface of the guide rail. The connection between the guide rail and the diaphragm can pass by means of the known connection methods, for example by gluing, screwing, riveting.

With the aforementioned color design of the guide rails or with the aforementioned panels on the guide rails together with the closure flap ensures that the shading system is completely installed in the retracted state in the facade and has the same appearance.

The shading system can assume various states. The retracted state refers to the state of the shading system when the fabric, as far as this is allowed by the system, is rolled onto the roll and the guide device is sunk as far as possible in the facade. When extended state, the state is referred to, in which the tissue or the downpipe is no longer in the same position in the guide rail, as in the retracted state. The drop tube carries in the extended state no weight of the guide device. The transition state is the state of the shading system between the retracted state and the extended state of the shading system. The tissue or the downpipe can assume different positions in the guide rail. In this case, the highest position of the downpipe in the guide rail is referred to as the upper end position. The lower end position refers to the lowest lying position of the fabric or the downpipe in the guide rail. The positions lying between the upper and lower end positions are referred to as intermediate positions.

If the shading is not used, the shading system is in the retracted state. When the shade is used in its entirety, the shading system is in the extended state and the drop tube is in an intermediate position or in its lower end position.

The retracted state of the shading system is achieved by rolling the fabric onto the roll by the drive until the motor limit switch shuts off the drive due to a maximum force achieved by a motor limit switch. By rolling up the fabric, the downpipe is moved in the guide rails up until it is present between the inner and the outer connection bar, that is until the downpipe reaches its upper end position. The drive further rolls up the tissue, the shading system is in the transitional state, until the inner sides of the guide rails abut against the stop. At that moment, the force needed to roll up the fabric increases until the maximum force is reached. When this is reached, the engine shuts off. When retracted, the outer surface of the guide rails or the respective possible apertures on the guide rails is approximately on the same plane as the outside of the facade.

The stop in combination with the fastening profiles with guide rods and the pull through the fabric / downpipe brings the stable position of the shading system in the retracted state. The advantage of using the motor limit switch for rolling up is that the fabric is always rolled up until the drop tube in its upper end position and the shading system are in the retracted state. Because the motor limit switch compensates for changes in length of the fabric, because it is rolled up until a certain counterforce is reached. This means that "more" fabric is rolled up, so that the façade always looks the same when the shading system is retracted, because it always retracts completely, causing changes in the length of the fabric due to temperature fluctuations, stretching or the age of the fabric are caught and do not affect the look.

The lower end position of the downpipe is defined by a position limit switch defined in the motor, the fabric is unrolled from the roller until the motor has approached the corresponding position and thus the downpipe has reached the corresponding position. This position is defined by a position limit switch coupled to the controller and the motor. The guide frame is in the position which is defined by the stop profile or the stop plate, which rests on the lower end of the main box. The position limit switch of the motor brings in the use of the advantage that it can be easily reprogrammed when changes result, for example, in the tissue length, which require a correction. When retracted, the shading system is held in place by the engine. The movement of the guide frame in the transitional state is controlled by the engine and gravity. In doing so, the motor determines the movement possible, which is achieved by gravity.

In the retracted state as well as in the transition state of the shading system, the weight of the guide frame is carried by the tissue or the tissue connected to the downpipe. The weight is transferred via the roller to the roller housing, this passes the weight on the mounting rails on the rear end of the mounting box and so on the inner facade level on.

In the extended state of the shading system, the weight of the guide frame is transmitted via the stop profile or the stop plate to the lower end of the main box and thus finally to the facade.

The distance that is in the extended state of the shading system and the downpipe in an intermediate position or the lower end position between the fabric and the outside of the facade that is the window, is chosen so that the air cushion between the two elements for insulation and ventilation is optimized ,

The states of the shading system and the positions are matched and they follow an order given by the system.

The sequence of the states of the shading system and the positions of the downpipe are given below. The following abbreviations are used:

BA Extended state of the shading system

BE Retained state of the shading system

BU Transition state of the shading system Upper end position of the downpipe

Lower end position of the downpipe

Intermediate position of the downpipe

The process shown above, when lowering the fabric, is described in words as follows:

AI. The shading system is in the retracted state at the first sequence point and the drop tube is in the upper end position.

A2. The transitional state of the shading system is achieved from the first sequence point by the unrolling of the fabric and the concomitant movement of the downer tube relative to the roller. The drop tube remains but during this sequence point in its upper end position in the guide frame, the guide frame itself moves that drop tube remains relative to the guide frame in a same relative position.

A3. If the fabric is further unrolled, the third sequence point is reached, in which the stop profile and the stop plate at the top of the window or the frame of the window are pending. The drop tube is still in its upper end position. This state lasts only very short in the liquid process, because the downpipe is immediately compared to the guide rails effectively or absolutely moved and thus comes into the intermediate position and thus follows the fourth sequence point. A4. The fourth sequence point refers to the visible from the outside unrolling of the tissue and the lowering of the downpipe in the guide rail in the extended state of the shading system.

A5. The fifth state is the final state of the shading when the fabric is unrolled so that the downpipe is in its lower end position.

The shading system is here in the extended state.

The lifting of the tissue is achieved by the reverse order of the sequence points, the tissue is rolled up again on the roll. The order of the sequence points is characterized in that only one state or one position (either a state of the shading system or a position of the downpipe) changes between the sequence points.

The guide frame or the lower ends of the left and right guide rails can be connected for stability reasons. For this purpose, a cross connection can be attached to the lowest end of the guide rails. As a result, the facade must have a further recess for receiving the cross-connection, so that the continuous surface can be created. Preferably, however, the design is chosen such that no cross-connection is realized at the lowest end of the guide rail.

The whole system can be created from standard elements of shading system technology and mechanical engineering. Roller housings with roller, bearing and drive correspond to standard components, which can only be adapted to the present system in a few points.

The fabric is also a standard component. The fabric of the shading system may be made of a variety of materials and combinations of materials. Preferably, the fabric is of a textile type and made of natural fibers and / or plastic fibers. It is possible that the The fabric may also have a coating, for example an impregnation, so that a lotus flower effect is achieved and in the case of rain, it ripples off the tissue. Further, it is also possible that the fabric is made of a different material such as metal or a composite material.

The guide rails are also a standard element, which is directly related to the tissue and usually comes from the same manufacturer. Depending on the design, the fastening rails can be the same product as the guide rails.

The various materials that are used for the mechanical elements such as connecting strips, fastening profiles, guide rod, stop, stop plate, upper vertical extension, baffle can be of various types, for example of a material such as stainless steel, aluminum or a plastic in particular a UV durable plastic.

It is possible that, constructively, some of the functional elements may be grouped together or may be separately formed and joined by means of known joining techniques. For example, stop profile and stop plate can be paired or the upper vertical extension of the guide rail and the baffle. In the case of the former, the outer connection strip and, in the case of the second, the inner connection strip can also be formed directly. Finally, it is also possible to make the whole assembly on the guide rails from one part.

The outer connection strip can be formed on the baffle so that the connection strip from the outside, when looking at the facade, is not directly recognizable. In that case it is arranged behind the baffle. The closure flap, which closes the main box of the mounting box on the outside of the facade, is mounted on the upper end of the blind box or of the mounting box by means of one or more hinges and abuts on the side opposite the hinge on the baffle or on the outer connecting strip. Gravity holds the flap in place. In the retracted position of the shading system, the position corresponds to a vertical orientation of the shutter, in all other states of the shading system, the position of the shutter corresponds to the plant this on the baffle. Furthermore, it is also possible to hold the closure flap on the one hand by suitably mounted springs in the mounting box of the guide device or on the guide frame in position. In addition, it is also possible to use a mechanism which movably connects the guide frame to the closing flap and fixes the position of the two elements relative to one another, depending on the position of the guide frame. Furthermore, it is possible to design a system with magnets, which ensures the positions of the flap. In particular, in the retracted position of the shading system, the flap can be held in position by appropriately mounted magnets. The closure flap can also be designed in two parts, so that, for example, a metal sheet forms the inner side, is present as standard and is connected to the hinge, while the outside is occupied by a decorative element. The decorative element is accordingly applied to the sheet, the two elements together form the flap. The decorative element is kept, for example, in the facade color.

If the shading system is transferred from the retracted state to another state, then the closure flap is opened or pressed. She moves around the turning center, which is the hinge. The guide frame moves out of the facade and the guide plate of the guide frame is thereby brought to the flap in Appendix. By the movement of the guide means, the closure flap is pressed together with this.

The guide rails or the panels, which can be mounted as a variant on the guide rails, and the closure flap serve in the retracted state of the shading system to continue the outside of the facade. Furthermore, these elements also have the function of protecting the entire inner mechanics, electrics and electronics from the effects of the weather such as rain. The guide rail, the panels and the flap close the star box to the outside.

The guide rails, and if panels are also used, are arranged in the retracted state of the shading system so that their lower ends are at the same height as the lower end of the star box.

The shading system with its entire mechanics is mirror-symmetrical except for the drive. The drive can be formed only on one side or on both sides. The embodiment which is described in this description for one page is also mirror-symmetrical for the counterpart.

The shading system can cover different sized areas of the window. Preferably, in each case the entire window is shaded by the shading system, but also a partial embodiment of the shading is possible. So it is conceivable that, for example, in floor-to-ceiling windows in buildings, only the upper part is equipped with the shading system, but not the lower.

The building or the facade has a U-shaped recess in which the shading system can be mounted. The shading system according to the invention can be installed in different ways on the building or in the facade. It is possible to put the system completely together in individual parts or smaller assemblies directly at the destination.

Preferably, the system is assembled in the mounting box, so that an installation ready module is created, which can be used in the simplest way in the U-shaped Ausnehm in the facade. During installation, it is then only necessary to mount the module on the inside of the facade, for example, to screw it on, to connect the power supply and the control and, if necessary, to fine-tune the limit switches for the retracted and extended states.

The control of the shading system can be done centrally via the building services. Furthermore, it is possible to control the shading system window by window or room by room, so that the optimal shading can be achieved. Of course, various control options can be superimposed, so that, for example, the shading system in the evening or in strong winds that could damage the system can be converted by a central pulse in the retracted state.

The control of the Beschatlungssystems can cover various special functions. In particular, the controller may be set to prevent accidental leaving of the shade system in the extended state. For example, by a timer, which specifies that the system is transferred to the retracted state at some point in time. However, it may also be specified that the system is automatically transferred to the retracted state if the drop tube deviates less than 20, preferably less than 10 cm, from the upper end position. The means that the system is transferred to the retracted state, when virtually no shade is donated by the tissue.

Of course, the shading system can also be used for the darkening of the rooms or for privacy. The difference between the different systems is only the choice of fabric to use. It is also possible that several functions can ultimately be perceived with one tissue. For example, sun protection during the day and privacy at night.

The invention also relates to a building, in particular a building, comprising:

- A facade, comprising a, in particular continuous, facade surface and at least one window surface;

- A shading system according to any one of claims 1 to 15 for shading the window surface.

The facade surface is formed by the outer surface of the at least one window surface by being arranged in the alignment of the facade surface. The shading system is arranged in the retracted state behind the facade surface and in the extended state in front of the facade surface.

Above and to the side of the window surface elongated recesses may be provided in the facade for sinking the shading system with the guide means behind the facade surface. The elongated recess above the window surface is in particular horizontal and the elongate recesses laterally of the window surface are arranged in particular vertically.

In the views shown in Figs. 1 to 8, the downpipe position is not always shown, but according to the views described above in words, it is indicated where the downpipe is located. Certain views may also occur in a different position of the drop tube in an identical manner. In Figs. 9 and 10 are shown views illustrating the transition upon lowering of the fabric 22 from the condition shown in Figs. 1 to 4 to those shown in Figs. The transitional state of the shading system BU with the drop tube 23 in the upper end position FO is shown in FIG. 9, which corresponds to the point of departure A2. FIG. 10 shows the extended state of the shading system BA with the drop tube 23 in the intermediate position FZ, which corresponds to the sequence point A4.

FIG. 1 shows how the arrangement shows a plan view of the outside 80 of the facade. Visible are the various elements that are arranged on the surface of the outside 80 of the facade. In the center is the window 81. Laterally there are the guide rails 40 'and 40 "." On the guide rails 40', 40 ", that is, the outer side 41 of the guide rail, said apertures can be mounted. At the upper end of the window 81, the flap 1 1 is arranged. The arrangement as shown is integrated directly into the facade.

Schematically shown are the limits of such an element or the continuation options for the further arrangement of other elements of the facade or windows in the form of continuing lines.

Not directly visible, since hidden behind the elements on the facade, the side walls of the mounting box 2. They are schematically indicated in Figure 1 by reference numerals with dashed lines. At the upper end is the upper end 4 of the mounting box 2. On the sides are the left and right lateral ends 5 ', 5 "of the mounting box 2, which is from the main box 3 into the left and right lateral box parts 10', 10". of the mounting box 2 is enough. At the lower end is located in the lateral box parts 1 0 of the left and right lower end 6 ', 6 "of the mounting box 2. Inside the side box parts 1 0', 10" of Montagekasteiis 2 are the left and right side inner End 7 ', 7 "of the mounting box 2, between these two statements at the bottom of the main box 3 is the lower end 8 of the main box 3 of the mounting box 2. In Figure 2 is a view into the starter box 1 and the mounting box 2 is shown Viewed as seen from the right lateral conclusion in the direction of the window 81 (position II in Figure 1) .This figure corresponds to a view into the lateral box part 10. In the upper area of the mounting box 2 is in the main box 3, the roller housing The cylindrical roller 21 is mounted with the fabric 22 thereon in the roller housing 20. The roller 21 is indicated by dashed lines in Figure 2, since it is not visible The roller 21 is laterally mounted in the roller housing 20, so that it is about its longitudinal axis The roller housing 20 in turn is attached to the mounting rail 60, which in turn at the rear end 9 of the mounting box 2 is fixed. The roller housing 20 is not movably mounted. The mounting box 2 in turn is attached directly to the building on the inner facade level 82 and fixed to this immovable. The roller 21 is driven, that is, it can be rotated with the drive about an axis which corresponds to the longitudinal axis of the cylinder. The drive is a motor which is arranged directly in the roller 21 in it.

On the left side, the outside 80 of the facade is shown. This is continued by the flap 1 1 and the guide rails 40. The closure flap 1 1 is fastened in the present case with a hinge 12 at the upper end 4 of the mounting box 2. As shown, it is vertically aligned in the retracted state of the shading system BE and lies with its inside on the baffle 45, on the outer connecting rail 44% of the upper vertical extension 43 of the guide rail 40 and the guide rails 40 at. If the flap 1 1 is moved, it rotates in the direction of rotation V about the hinge 12th

The guide rail 40 is connected to the fastening rail 60 by means of the fastening profiles 61 ', 61 "and the guide rod 62. To this end, fastening profiles 61', 61", which are connected to one another by a guide rod 62, are attached to the guide rail 40 as well as to the fastening rail 60 , In the retracted state of the shading system BE, the guide rail 40 bears against the stop 63, which defines the end position.

The inner side 42 of the guide rail 40 bears against the stop 63, while the outer side 41 of the guide rail 40 forms part of the outer side 80 of the facade. The firm connection of the fastening profile 61 'with the fastening rail 60, which in turn is fixed to the rear end 9 of the mounting box 2 and thus with the inner wall surface 82, entails that the guide rod 62 rotates about this fastening profile 6Γ. The direction of rotation of the guide rod 62 is indicated in Figure 2 with R, rotation center is here as mentioned the attachment profile 6Γ.

At the upper end of the guide rail 40, the stopper profile 46 and the upper vertical extension 43 of the guide rail 40 is arranged. Behind the stop profile 46 in the extension of the guide rails 40 in the viewing direction of Figure 2, the connecting strips 44 and the stop plate 47 are arranged, these are not visible in the present view. Next, the baffle 45 is disposed behind the vertical extension 43 of the guide rail 40 in the viewing direction of Figure 2, which is also not visible in the present view. It can be clearly seen that in the retracted state of the shading system BE the lower end of the guide rail 40 is approximately at the same height as the lower end 6 of the mounting box 2. The mounting box 2 is shown in Figure 2 with different elements. The upper end 4 of the mounting box 2, and this set against the lower end 8 of the main box 3 of the mounting box 2 is shown. The rear end 9 of the mounting box 2 is shown, this continues seamlessly into the already mentioned elements of the mounting box 2 and also directly in the lower end 6 of the mounting box 2. The lower end 6 of the mounting box 2 as well as the lower end 8 of the main box 3 is inclined as shown in FIG. This makes it possible that at most in the mounting box 2 collecting water from the mounting box 2 is derived. So that this water then does not get into the facade, the lower end 6 of the mounting box 2 is continued until the facade - he has as a conclusion a curved drainage edge. The most visible element of the mounting box 2 is the lateral inner end 7 of the mounting box 2, this continues from the lower end 6 of the mounting box 2 to the lower end 8 of the main box. FIG. 3 shows a section through the main box 3 of the mounting box 2 or through the blind box 1 and the mechanism. The cut is in the middle of the window 81 or in the middle of the roller 21 (see position III in Figure 1). The difference from Figure 2 shows that the leadership of the fabric 22 from the roller 21 through the connecting strips 44 44 "to the downpipe 23 is more visible and that also more details such as the arrangement of the stop profile 46 and the stop plate 47th and the upper vertical extension 43 and the baffle 45 are visible. The roll 21 is cut but stylized as a full roll. However, the roller 21 is preferably not designed as a solid body, because in it, among other things, the drive is arranged. Also not shown in detail is the reeling of the fabric 22 on the roll 21, which is known to the skilled person and the general public from everyday use. The drop tube 23 is shown as a solid profile, this is also stylized, since the attachment of the fabric is assumed to be known and will not be further described at this point.

The fabric 22 passes from the roll 21 between the outer tie bar 44 'and the inner tie bar 44 ", before it enters the guide rail 40 and is secured to the drop tube 23.

The fabric 22 is unrolled from the roller 21 when the roller 21 rotates in the direction of rotation DS. Conversely, upon rotation in the direction of rotation 1) 0, the fabric 22 is rolled up onto the roll 21.

The drop tube 23 is shown in its upper end position FO. It is in abutment with the outer and inner connecting bars 44 ', 44 ". The drop tube 23 is connected to the fabric 22 by known means.

Between the stop profiles 46, which are located above the left and right guide rails 40 ', 40 ", the stop plate 47 is formed, which continues towards the inner facade level 82, the inner connecting bar 44" or is attached seamlessly thereto. The stop profile 46 together with the stop plate 47 form the positioning element for the guide frame 48, in the extended state of the shading system BA.

Shown cut is the window 81 and other elements of the house (83, 84). The elements of the Flause are represented stylized and shown purely schematically. A wall element lies above the window 81 and the further window 84. Die various elements of the house are arranged so that in the facade in plan view (such as in Figs. 1 and 5), a U-shaped recess is formed. The different elements can be replaced by other or several others.

The window 81 is located in the arrangement under the lower end 8 of the main box 3 of the mounting box 2. The sectional view also shows that two fixing rails 60 are used, one to the left and one right of the lower end 8 of the main box 3 of the mounting system compared to Figure 2 , This also means that a fastening rail 60 is mounted in each lateral box part 10 ', 10'. In the sectional illustration in this figure, the left-hand fastening rail is visible, while in Figure 2 the right-hand fastening rail was visible.

In the roller housing 20, the roller 21 is visible in a sectional view. The drive of the roller 21 is at the left or right end of the roller 21 in the roller 21 in it, that is actually arranged visible in section of the corresponding location. The drive is not shown.

FIG. 4 once again shows the retracted state of the shading system BE, this time in a horizontal sectional view. Clearly visible is the arrangement of the mechanism for the movement of the guide rails 40 ^" , 40", which are located on the left and right of the window 81 and the wall elements 83.

Shown schematically in the left and right guide rails 40 ', 40 "is the guide of the fabric 22 and the drop tube 23. The fabric 22 and the drop tube 23 are realized between the left and right guide rails 40', 40" without further support.

'The mounting profiles are fixed 61 "on the guide rails 40', 40 ^'. In the bulky guiding the guide rod 62 is attached, which, because the assembly rotates about the mounted on the mounting rail 60 mounting profile 6. Not shown in Figure 4, due to the arrangement of the section, the stop 63, which rests directly on the inside 42 of the guide rail 40 ', 40 ", while the outside 41 of the guide rail 40 forms part of the outside 80 of the facade.

In this view, once again shown from another perspective, as the mounting box 2 and the rear end 9 of the mounting box 2 is attached to the inner facade level 82 and rests. This also shows the further thawing, namely that the fastening rail 60 rests directly on the rear end 9 of the mounting box 2.

The also visible window 81, in a sectional view, is mounted between the lateral box parts 10 ', 10 "of the mounting box 2. Combined with the other figures, it can be seen that the window 81 and the other facade elements (wall elements 83) on three sides of Mounting box 2 are included., Thus, the window 81 is finally shaded.

The various side walls of the mounting box 2 are also visible in the corresponding lateral box parts 10 ', 10 "in this view from the mounting box 2. Thus, in the left side box part 10', the left side end 5 'and the left side inner end 7' are visible. of the mounting box 2 visible, while in the right side box part 10 "the right side closure 5" and the right side inner end 7 "of the mounting box 2 are visible. Further, in the left lateral box part 10 ", the lower left end 6 'of the mounting box 2 and in the right side box part 10" the right lower end 6 "of the mounting box 2 can be recognized.

The extended state of the shading system BA with the drop tube 23 in the lower end position FU is shown in FIG. 5 in a plan view of the outer side 80 the facade shown. The system is no longer completely arranged in the facade, which is shown in various details, but can be better recognized in the following figures. In the upper area, the closure flap 1 1 can be seen, which is arranged at an angle to the facade in this state (in this view, recognizable by the smaller projected area compared with FIG. 1).

The window 81 is not visible in this view because it is hidden by the fully extended tissue 22. In the center is now the fabric 22, which shows itself after passing through the connecting strips 44 ', 44 "on the outside 80 of the facade.The outer connecting strip 44' is visible in the view, directly above the baffle 45 is arranged.

The drop tube 23 is in its lower end position U, which is located at the end of the guide rails 40 ', 40 ", which are now slightly lower than in the retracted state of the shading system BE, this being recognized in FIG Guide rails 40 ', 40 "are no longer in the continuation of the facade structure. The vertical upper extension of the guide rail 43 and the stopper profile 46 are not specifically shown in this view due to their thin design.

The further figures 6, 7 and 8 show in analogous views to the preceding Figures 2. 3 and 4, the shading system or parts thereof, but in a different state. FIG. 6 shows a view into the starter box 1 or the mounting box 2. The view is shown as it is encountered when looking from the right side conclusion in the direction of the window 81. FIG. 7 shows a section through the main box 3 of the assembly box 2 or through the star box 1 and the mechanism. The section is in the middle of the window 81 or in the middle of the roller 21. In Figure 8 is again the extended state of the shading system BA shown, this time in a horizontal Schniltansichl.

In contrast to the previous illustrations (in FIGS. 1 to 4), the illustrations in FIGS. 5 to 8 show the shading system in the extended state BA and the drop tube 23 in its lower end position FU. This can be seen in the fact that different moving elements are in a different position. For example:

The fabric 22 is unrolled so far that the drop tube 23 is in its lower end position FU.

The guide frame 48 is lowered and now protrudes beyond the outside 80 of the facade. The position in the horizontal direction is determined by the combination of the fastening profiles 6Γ, 61 "with the guide rods 62, which control the extension movement depending on the position of the drop tube 23. The stop profile 46 defines the end position.

The stopper profile 46 and the stopper plate 47 rest on the lower end 8 of the main box 3, above the window 81.

• The flap 1 1 is issued and is now only on a line on the upper vertical extension 43 of the guide rail 40 and the baffle 45 on.

In Figure 6 is specifically seen that the stopper 63 is free, he has no function in the extended state of the shading system BA. Furthermore, it can be seen in this figure that the lower end of the guide frame 48 or the lower end of the guide rails 40 is lower than the lower end 6 of the mounting box 2.

In particular in Figure 7, the guidance of the fabric 22 can be seen. The fabric 22 is at least partially unrolled from the roll 21, in part because the Tissue 22 is usually slightly longer in length than the length actually required and thus still a portion of the fabric 22 is on the roller 21. The fabric 22 is passed between the inner and outer tie bars 44 ', 44 "and is thereafter guided in the guide rail 40. The lower end of the fabric 22, which is located in the drop tube 23, is not shown.

The Ansclilagsprofil 46 is as already described at the lower end 8 of the main box 3 at. The mounting profiles 61 with the guide rods 62 carry no weight, they are responsible only for the positioning of the guide frame 48. The weight is carried by the Ansclilagsprofil 46 and the stop plate 47.

The arrangement of the mechanism for the movement of the guide rails 40 ', 40 ", which are located to the left and right of the window 81, is shown clearly visible in Figure 8. Explicitly visible is how they are in a different position relative to FIG The extended state of the shading system BA is shown.

The guide rails 40 ', 40 "are shown opposite the original position and the outside of the facade 80, the guide rods 62 that position these positioning points have a larger projected area in this view than in FIG. 4.

Also well visible is the already mentioned air cushion between the fabric 22 and the window 81, which serves the ventilation and insulation.

It can also be seen that both the fabric 22 and the downpipe 23 are guided in the guide rail 40 'and 40 "respectively These elements correspond to standard components, as well as the interface between the elements, which is why this is shown schematically in the figure and will not be described in detail. The further facade is not shown in FIGS. 4 and 8. Basically, this connects directly to the mounting box 2, this is namely embedded in the facade. Wall elements of the house 83 and further windows 84 are shown schematically.

FIG. 9 shows the transition state of the shading system BU with the drop tube 23 in the upper end position FO. The illustration is a section through the main box 3 of the mounting box 2 or through the blind box 1 and the mechanics. The cut is in the middle of the window 81 or in the middle of the roller 21st

The Anschlagsprofü 46 and the stop plate 47 is not yet in abutment lower end 8 of the main box 3. The drop tube 23 is still in the upper end position FO.

The position of the drop tube 23 is due to the fact that the guide frame 48 can still move and the position of the drop tube 23 does not change, as long as the guide frame 48 can be moved. The entire weight of the guide frame 48 is transmitted through the drop tube 23 on the fabric 22 and so on the roller 21. The bearings of the roller then transferred to the roller housing 20, which transmits to the mounting box 2. This leads the power over the screw connection on the facade of the building. FIG. 10 shows at the same position as FIG. 9 the shading system in its extended state BA and the drop tube 23 in an intermediate position FZ. The representation is in turn a section through the main box 3 of the mounting box 2 or through the blind box 1 and the mechanics. The cut is in the middle of the window 81 or in the middle of the roller 21st This figure is characteristic of the externally visible lowering of the tissue 22 for the shading and for the shading states in which the drop tube 23 is not in the lower end position FU. In this state, only the roller 21 moves. The fabric 22 and the downpipe 23.

While the drop tube 23 is in an intermediate position FZ, it is in the guide rail 40 and not in the upper and not in the lower end position FU, FO. The intermediate position FZ of the downpipe 23 allows at least partial shading.

The drop tube 23 is in an intermediate position FZ until it reaches the lower end position FU of the drop tube 23, that is, until the tissue 22 does not continue to roll.
