Description

Technical field

[0001] The present invention relates to a shading device according to the preamble of claim 1. The housing box of this shading device is particularly designed to be fastened in a facade of a building by means of the lintel mounting method or to be fastened to a wall and / or to a facade of a building by means of the projection mounting method.

[0002] The present invention further relates to a method for mounting a related shading device. State of the art

[0003] Shading devices, such as blinds, venetian blinds, or roller shutters, are commonly used to regulate the penetration of light and heat while protecting privacy. Electrically driven shading devices use motors to raise or lower a shading element, such as a roller blind.

[0004] Electrically driven shading devices work by using a motor, for example a tubular motor, which is built into the housing box and attached to one axial end of a winding shaft.

[0005] The motor has a motor cable of a defined length for power supply. This motor cable is connected to the motor either detachably or permanently. For example, the motor cable can be plugged axially into the motor via a plug-in connector. Previous solutions required disassembly of the motor to access the plug-in connector.

[0006] To establish a connection to a power and / or data source, the motor cable is equipped with a connector element, a motor connector element, at its end facing away from the motor. Figure 2In the shading device shown, the connector is located outside the roller blind's housing box to ensure easy access for maintenance work. The connector is placed either on top of the housing box or behind it. Additional elements (e.g., metal sheets) are required on site to hold the connector in place. Access to the connector is often very difficult, particularly when the product is installed in a lintel recess. To visually conceal the connector in a projection element and protect it from the weather, the connector can be housed in its own housing.

[0007] There are also special junction boxes that are mounted on top of the box and connected to it. However, this further increases the installation space of the housing box. Description of the invention: task, solution, advantages

[0008] Based on the disadvantages and deficiencies outlined above, and taking into account the outlined prior art, the present invention is based on the object of developing a shading device of the type mentioned above and a method of the type mentioned above in such a way that the shading device is compact and space-saving, while simultaneously ensuring simple assembly, handling, and maintenance of the electrically driven shading device. In particular, the motor connector element should be arranged in a visually concealed and weatherproof manner, yet still be accessible for servicing.

[0009] This object is achieved by a shading device having the features specified in claim 1 and by a method having the features specified in claim 13. Advantageous embodiments and expedient further developments of the present invention are characterized in the respective subclaims.

[0010] The present invention is therefore based on integrating the motor connector element into the housing box. The housing box comprises either a service or inspection opening arranged on the bottom and on the front, through which the interior of the housing box and the motor connector element can be accessed, and a housing opening designed to accommodate a cable, or the housing box comprises a service or inspection opening in the region of the bottom for accessing the motor connector element and a housing opening in the region of the front of the housing box, for example an open front, for accessing the interior of the housing box, in particular for accessing the top of the housing box and / or a side wall of the housing box facing the motor, for example for accessing at least one cable positioning element arranged in the housing box.The access to the interior of the housing box provided according to the invention allows an additional, particularly building-side, electrical cable with a cable connector element designed as a counterpart to the motor connector element to be introduced into the interior of the housing box. This makes it possible to integrate a building-side power supply into the housing box.

[0011] Integrating the building's power supply into the enclosure simplifies the installation of the shading device, eliminating the need for a separate enclosure for the connector or additional connector assembly. This saves time and effort during installation.

[0012] Another advantage is the space savings. Since the power supply is integrated into the enclosure, no additional space is required for external power supply components or an external enclosure for the connector. This is advantageous in confined spaces, especially for header mounting.

[0013] In addition, the motor connector element is arranged space-savingly between the winding shaft and the bottom of the housing, specifically mounted on the bottom of the housing. This achieves a particularly compact housing design with a low housing height and integrated connector connection.

[0014] Furthermore, the present invention significantly simplifies maintenance of the shading device. If necessary, the integrated connector elements of the motor and cable can be easily accessed via the service opening in the bottom of the housing box. This simplifies maintenance and contributes to the long-term functionality of the shading device.

[0015] In the shading device according to the invention, the motor connector element is integrated into the lower part of the housing box in the operating position, particularly in the case of front-mounted and lintel-mounted installations. However, the building-side cable enters from above or at the same height as the winding shaft, for example, from the front or rear.

[0016] In this context, the terms "top", "bottom", "front", "back", "above", "below", "horizontal", "vertical", "above", "below", "from above", "from below", "inside", "outside", "inwards", "outwards", floor, top, front, back, side wall, etc., indicate the positions and orientations that are given for the position of use, i.e. the intended use and the intended arrangement, of the shading device and for an installer / service technician who is then standing in front of the shading device and looking in the direction of the shading device.

[0017] To prevent the additional cable, particularly the one on the building side, from getting into the area of ​​the winding shaft, such as the fabric take-up, the housing box advantageously comprises at least one cable positioning element in the area of ​​its front side and / or in the area of ​​its side wall. The cable positioning element is designed to arrange or position a cable at a distance from the winding shaft. The cable positioning element can guide and / or hold the cable.

[0018] The additional cable with cable connector element can therefore be laid neatly in the box by the cable positioning element arranging the additional cable at a distance from the winding shaft on its way from an area of ​​the housing box arranged above the winding shaft and / or at the same height as the winding shaft to the motor connector element arranged in the interior of the housing box and below the winding shaft.

[0019] With projection installation, the shading device is mounted on the façade, while with lintel installation, the shading device is fully integrated into the lintel, resulting in a clean façade appearance. The choice of installation method depends on various factors, such as the planning / implementation time of the shading device, the installation situation, and aesthetic preferences.

[0020] With the current state of the art, accessing the connectors is often challenging when installing shading devices in lintel recesses due to the limited space. Therefore, a specialist will appreciate the ability to easily install the connector with the pre-assembled connector element of the building-side cable in the housing box, especially in lintel installations. This innovative solution is provided by the present invention.

[0021] The motor connector element can be mated with a cable connector element of an electrical cable, which serves as a counterpart to the motor connector element. The two connection elements of the connector are referred to as a plug and a socket. The plug is the male connection element with pins or contacts, while the socket is the female connection element with corresponding sockets or openings. The two components are connected by inserting the plug into the socket to establish an electrical connection for transmitting power and / or digital data. The connector can therefore be designed in the manner of a so-called Hirschmann connector.

[0022] The connector is used to connect the motor to a power and / or signal and / or data source. For example, the cable connector element can be a connection element for a building-side power cable or an installer / service technician test cable. In the operating position, the motor connector element in the enclosure box is connected to a customer-supplied or building-side cable with a pre-assembled cable connector element. The customer-supplied or building-side cable enters the enclosure box at the top or front of the enclosure box.

[0023] According to the invention, at least one region of the base of the housing box is designed as a service or inspection cover suitable for providing access to the motor connector element and pivotably and / or detachably connectable to a body of the housing box. The base of the housing box thus has a service opening that allows access to certain components inside the box for performing assembly, maintenance, and / or repair work. The service or inspection cover can be implemented, for example, in the form of a flap, a door, a removable panel, or a removable service cover and allows easy access without having to open the entire housing box.

[0024] The additional cable, in particular on the building side, can enter the interior of the housing box through a housing opening arranged above the winding shaft and / or at least partially at the same height as the winding shaft, for example through the housing opening on the front side or through a recess in the top side of the housing box. In the use position of the shading device, the additional cable enters the housing opening on the front side or through the housing opening on the top side and has an external cable section arranged outside the housing box and a housing-box-side cable section arranged in the area of ​​the housing box. In an advantageous embodiment of the present invention, the housing-box-side cable section runs from a section of the housing box arranged above the winding shaft to the motor connector element arranged below the winding shaft and in the interior of the housing box.Above the winding shaft refers to a position or area located above, in particular vertically above, the winding shaft, for example between the winding shaft and the housing box. Below the winding shaft, on the other hand, refers to a position or area located below, in particular vertically below, the winding shaft, for example between the winding shaft and the bottom of the housing box. The motor connector element and, if applicable, the cable connector element, i.e., the connector, are located in this area.

[0025] Advantageously, the housing box has the cable positioning element on its rear side facing the wall and / or facade in the use position, and / or on its front side facing away from the building or the service technician in the use position, and / or on its side wall facing the motor. This cable positioning element enables the arrangement of the cable area on the housing box side and, optionally, also the motor cable, at a distance from the winding shaft. This enables an orderly and space-saving integration of the power cable on the housing box side and the motor cable, reliably preventing cable damage from the winding shaft and resulting short circuits. This contributes to the safety and longevity of the shading device.

[0026] Furthermore, the housing box, in particular the base of the housing box, preferably comprises at least one cover profile that is displaceably movable between a covering position, in which the cover profile covers the motor connector element, for example the connector, and a release position, in which the cover profile allows access to the motor connector element, for example the connector. To provide the displaceable mobility, the cover profile can be displaceably mounted on a guide rail of the service or inspection cover, in particular of the base designed as a service or inspection cover and / or the front of the housing box designed as a service or inspection cover.

[0027] To facilitate handling, the motor cable is longer than the direct route from the motor to the service or inspection cover. The motor cable therefore advantageously includes a defined excess length. To prevent the motor cable from coming into contact with the winding shaft, the cover profile is advantageously designed to accommodate the motor cable, in particular to accommodate at least one loop of the motor cable formed due to the excess length.

[0028] In a housing box that can be attached using the front-mounting method and is completely enclosed in the visible area, the housing opening is advantageously located at the top of the housing box. To close the housing opening and position the electrical cable, the housing box advantageously has an upper cover element. The upper cover element is detachably connectable to the housing box and has a cable entry element designed to seal at least one cable opening in the housing box. The upper cover element allows on-site cables, including plug connectors, to be routed into the top of the box on site.

[0029] According to a preferred embodiment of the present invention, the service or inspection cover and the upper cover element interact in such a way that, in the position of use of the shading device, the upper cover element is held in the desired position by means of a form-fitting connection via the mounted service or inspection cover.

[0030] Advantageously, the cable entry element is made of a flexible material that adapts to the cable diameter and tightly encloses it, for example, plastic or elastomer. Alternatively, the cable entry element can also consist of several interlocking parts that create a watertight connection. The cable entry element serves to protect the cable from damage and abrasion on sharp edges and to prevent liquids, gases, or dirt from penetrating the interior of the housing body.

[0031] Preferably, the cable entry element has a cable opening designed to accommodate the electrical cable in the center. The cable entry element can have a slot-shaped recess for threading the cable.

[0032] The flexible material allows the cable entry element to be compressed so that it can be positioned in a recess in the upper cover element specifically designed to accommodate the cable entry element. The cable entry element tightly encloses the cable and the areas of the slot-shaped recess fit tightly together. This allows the electrical cable to be inserted into the housing box and the housing to be sealed watertight at the same time.

[0033] In order to fasten the cable feed-through element to the upper cover element, the cable feed-through element can have a circumferential groove which is designed to connect the cable feed-through element in a form-fitting manner to an edge of a recess in the upper cover element.

[0034] The top cover element can either cover the entire top of the enclosure box or just a portion of it. For example, the top cover element can be designed in the shape of a ridge and form a positive connection with the enclosure box. One advantage of partial coverage is that it is easier to attach the cable and cable entry element to the top cover element. This makes handling easier.

[0035] The entire base of the housing box can be designed to form a service or inspection opening, providing lockable access to the interior of the housing box. This allows access not only to the motor connector element but also to other components inside the housing box. This can simplify maintenance of the winding shaft and the shading element, for example. For this purpose, the base of the housing box can be connected to the housing box, for example, by means of a hinge connection.

[0036] In addition to the base of the housing box, a front side of the housing box facing the mounting side can also be designed as a service or inspection opening suitable for providing access to the motor connector element and detachably connectable to the housing box. For example, the inspection cover designed to provide access to the motor connector element can have an L-shaped cross-section element of the housing box that can be detachably connected to the housing box body and can be removed from the housing body, then providing access to the interior of the housing box.

[0037] In other words, at least a region of the bottom of the housing box and at least a region of a front side of the housing box can be designed as an inspection cover that can be detachably connected to the housing box, wherein the inspection cover is designed to provide access to the motor connector element and to the interior of the housing box.

[0038] The housing box can be made of various materials such as aluminum and / or plastic and / or wood.

[0039] Advantageously, the base of the housing box has at least one guide profile on each of its two long sides, which is designed to accommodate and secure a guide rail suitable for guiding the shading element. The motor connector element and the guide profile are each arranged below the winding shaft, in particular at least substantially at the same height, to ensure optimal arrangement and integration of the connector and guide.

[0040] The guide profile is advantageously designed to accommodate at least one fastening tab suitable for attaching the housing box to the guide rail. The fastening tab is slidably arranged in a guide groove of the guide rail and can be moved between a release position and a locking position. In the release position, the fastening tab is arranged at least predominantly in the guide groove, and the housing box can be removed from the guide rail. In the locking position, the fastening tab is arranged in the guide profile such that the housing box is securely fastened to the guide rail.

[0041] The guide rail serves to guide the shading element between an open position, in which the element is wound onto the winding shaft, and a closed position, in which it is unwound from the winding shaft. This allows the building opening to be protected from light and allows light to enter. Specifically, a shading element guide designed to guide the shading element is advantageously arranged in the guide groove for this purpose.

[0042] The fastening tab advantageously has a contour, in particular a projection, an inner bend or a nose, at its end facing away from the housing box, which in the locked position of the fastening tab is mounted on the shading element guide and in the release position of the fastening tab is arranged in an area of ​​the guide groove intended to receive the shading element guide.

[0043] This contour has the technical effect that the shading element guide can only be correctly inserted into the guide rail when the fastening tab is in the locked position. In other words, the contour ensures that the inner guide can only be closed during installation when the fastening tab has been fully pushed up. The contour thus enables error detection, known as a Poka-Yoke. Furthermore, the contour resting on the shading element guide in the locked position ensures that the fastening tab can no longer slip down once the guide is fully installed.

[0044] The present invention further relates to the use of at least one shading device according to the type set out above and / or a shading device mounted according to the method according to the type set out above for regulating the entry of light and / or heat through at least one building opening of a facade, a loggia or a balcony.

[0045] Finally, the present invention relates to the use of a housing box, in particular a housing box of the type described above, as a housing box for a shading device for regulating the entry of light and / or heat through at least one building opening of a facade, a loggia or a balcony, wherein the bottom of the housing box comprises at least one service or inspection cover (20; 20') which can be pivoted and / or detachably connected to the housing box, and the front side (34) of the housing box comprises at least one housing opening (36') suitable for providing access to the interior of the housing box, or the bottom and the front side of the housing box comprise at least one pivotable and / or comprise a service or inspection cover (20; 20') which can be detachably connected to the housing box, and the housing box comprises on its upper side (10) at least one housing opening (36) suitable for receiving a cable.

[0048] Identical or similar designs, elements or features are not included in the Figures 1 to 24 provided with identical reference symbols. Best way of carrying out the invention

[0049] To avoid unnecessary repetition, the following explanations regarding the embodiments, features and advantages of the present invention (unless otherwise stated) refer to both the Figure 1 shown shading device 100 as well as to the in Figure 10 illustrated shading device 102.

[0050] In the Figures 1 and 3 to 9 The first exemplary embodiment of the present invention illustrated in Figures 17 to 24 shows a shading device 100 that can be installed using the method according to the present invention. Specifically, a vertical fabric blind with a motor plug that can be integrated into the housing box on site is shown for front-mounted installations.

[0051] Arranged in the housing box are a winding shaft 40 rotatable about its longitudinal axis and an electric motor, for example a tubular motor, designed to drive the winding shaft 40. The electric motor is attached to one axial end of the winding shaft 40. Furthermore, a shading element 42, in particular a blind, a roller shutter, an awning or a curtain, for example a curtain made of fabric, cloth or material, such as a vertical fabric curtain, is attached to the winding shaft 30. The winding shaft 40 is designed to roll the curtain 42 onto the winding shaft 40 by rotating the winding shaft 40 in a first direction of rotation and to raise it into an open position, and to unroll it from the winding shaft 40 and lower it into a closed position by rotating the winding shaft 40 in an opposite direction of rotation.

[0052] The base 30 of the housing box has a guide profile 84 on each of its long sides, which can be placed on a guide rail 50 designed to guide the blind 42. For power supply, the motor has a motor cable 60 with a motor connector element, namely a motor connector 62, arranged vertically below the winding shaft 40 in the housing box and designed as a connection element of a plug-in connector.

[0053] The motor connector 62 can be joined to a cable connector element designed as a counterpart to the motor connector 62, namely a cable socket 76, of an electrical cable 70, such as a power cable or a test cable, introduced from the outside into the interior of the housing box, to form a plug connection designed to connect the motor to a power source and / or to a signal source.

[0054] To provide access to the motor connector 62, the base 30 and the front 34 of the housing box are designed as an inspection cover 20 that can be detachably connected to a body of the housing box. The service opening allows the electrical cable 70 with cable socket 76 to be routed from the outside of the housing box.

[0055] The inspection cover 20 is preferably connectable to the body of the housing box by means of a positive fit. To connect the inspection cover 20 to the body of the housing box in a positive fit, the front side 34 of the housing box can have a fastening structure 24, such as a groove or channel, which is designed to positively receive a counterstructure, such as a nose or projection, of the inspection cover 20 arranged on the top side 10 of the housing box.

[0056] The housing body therefore has an inspection cover 20 associated with the base 30 and the front 34 of the housing box, which is removable from the housing box and has an L-shaped profile in cross section.

[0057] As in the Figures 4 to 9 As shown, the housing body also has an upper cover element 12, which is assigned to a housing opening 36 and can be detachably connected to the housing box. The upper housing opening 36 can be closed in a visually clean, integrated manner using the upper cover element 12 and can, for example, be a punched-out portion of the upper side 10 of the housing box.

[0058] In the case of front-mounted installation, the housing opening 36 is arranged at a longitudinal end region of the housing box arranged vertically above the winding shaft 40 (cf. Figures 3 to 9 ). In the case of header mounting, the housing opening 36 can be arranged on the front 34 or front side of the housing box (cf. Figures 10 and 11). The cable socket 76 is thus formed by a cable gland 78 on an upper side 10 of the housing box facing away from the base 30 (cf. Figures 3 to 9 ) or on a front side of the housing box facing the mounting side (see Figures 10 and 11 ) arranged housing opening 36 into the interior of the housing box.

[0059] The upper cover element 12 (cf. Figures 3 to 9 ) covers the housing opening 36 or the cable outlet. It has a recess into which a detachably attachable cable entry element 16, namely a cable grommet, can be inserted. The cable grommet 16 has a cable opening 17 for passing through the electrical cable and a sealing body that encloses the cable and seals the cable opening 17. This ensures that no liquid, gas, or dirt can enter the interior.

[0060] When assembling the shading device 100 designed for front-mounted installation, the housing box can first be placed on the guide rails 50.

[0061] This is followed by the removal of the L-profile-shaped inspection cover 20 and the upper cover element 12 and the fastening of the power cable 70 to this upper cover element (cf. Figures 4 to 6 ). The housing box can be opened for service cases by removing the L-profile-shaped inspection cover 20 at the front and bottom.

[0062] The upper cover element 12 is a cover element that can be integrated separately into the upper housing opening 36. This upper cover element 12 can be inserted into the box profile from the front. As shown in Figure 1As shown, the upper cover element 12 can be supported by means of a fastening structure 14 in the region of the front side 34 of the housing box on the inspection cover 20 on a counter structure, in particular a tab, designed in the manner of a hinge connection and can be connected in alignment with the body of the housing box or with the housing box profile by fastening the inspection cover 20 by means of the hinge connection.

[0063] In the Figures 4 and 5 The upper cover element 12 has a drilled hole 15 next to the mounting structure 14 for attachment to the enclosure box. This drilled hole is optional. The positive connection provided by the mounting structure 14 with the access cover 20 securely fastens the upper cover element 12 to the enclosure box, so no additional fastening element is required.

[0064] To attach the power cable 70 to the upper cover element 12, the power cable 70 is first inserted into a slot 18 of the cable grommet 16 ( Figure 4 ).

[0065] Next, the cable grommet 16 with the power cable 70 is inserted into the upper cover element 12. The upper cover element 12 is, as shown in the Figures 4 to 6 shown, preferably in the form of a narrow rectangle, for example web-shaped or slat-shaped, and arranged at a lateral end region of the upper side 10 of the housing box.

[0066] The power cable 70 is then guided and laid laterally in the box by means of at least one first cable positioning element 80, 80' and is fastened with a further cable positioning element 82, for example designed as a cross plate (cf. Figures 1 and 6). The elements 80, 80', 82 provided in or on the box for cable routing and cable positioning prevent the power cable 70 from getting into the area of ​​the fabric take-up.

[0067] The two connection elements of the connector can then be coupled and stored in a cover profile 38, such as a connector channel, of the L-shaped inspection cover 20. The connector can be stored, for example, on the base 30 of the housing box.

[0068] The Figures 10, 11 , 14 and 15The shading device 102 shown is designed for lintel mounting. Since the housing box is integrated into the lintel in the use position, it does not have a front wall designed to cover the front side of the housing box. The housing box is therefore open toward the front side, or the front side 34 of the housing box is designed as a housing opening 36' suitable for providing access to the interior of the housing box.

[0069] The base 30 of the shading device 102 is designed as an inspection cover 20' and is pivotably mounted on the housing body.

[0070] In order to guide the power cable 70 on its way from the top side of the housing box to the motor connector 62 at a distance from the winding shaft 40, the shading device 102 comprises cable positioning elements 80' arranged in the area of ​​the top side 10 of the housing box and in the area of ​​the front side 34 of the housing box. As shown in Figure 10As can be seen, these cable positioning elements 80' can be arranged on a cable guide 81, for example on an L-shaped plate. In addition to the cable guide 81, at least one further cable positioning element 82, for example a cross plate, can be arranged on a side wall 35 facing the engine (cf. Figure 10 ). The cable guide 81 and the further cable positioning element 82 can be formed as separate elements or integrally with one another.

[0071] In this shading device 102 designed for lintel installation, the power cable 70 is attached to the cable positioning elements 80' for space reasons before the housing box is pushed up into the lintel. The plug connection consisting of the motor plug 62 and the cable socket 76 can be joined before or after the housing box is installed in the lintel. Furthermore, the inspection or service opening provided by the inspection cover 20' allows a plug connection consisting of the motor plug 62 and the power cable to be disconnected for servicing purposes with the housing box installed in the lintel and, for example, to connect a test cable to the motor plug 62 instead of the power cable.

[0072] To install the shading device 102 using the lintel mounting, the inspection cover 20' is opened, namely the bottom 30 of the housing box is pivoted (cf. Figure 11), the power cable 70 is fastened in the cable positioning elements 80', 82, the cover profile 38 is pushed aside until the plug connector is accessible, the electrical cable with cable socket 76 is connected to the motor plug 62 and the cover profile 38 is pushed back so that it protects the plug connector from the winding shaft 40, and the inspection cover 20' is closed.

[0073] The housing box can be mounted in the lintel after securing the cable in the cable positioning elements 80' or after connecting the cable socket 76 to the motor connector 62.

[0074] The two embodiments of a shading device 100; 102 according to the present invention shown above thus make it possible to integrate a building-side power cable 70 with a pre-assembled connector into the interior of the housing box on the construction site.

[0075] In the Figures 14 to 18the connection between the housing box and the guide rails 50 is shown.

[0076] Figure 14 shows an embodiment of a housing box that is mounted using the header mounting method. The guide structure of the housing box and the elements of the guide rail 50, in particular the fastening tab 52 and the guide adjustment system described below, can also be provided in a shading device 102 designed according to the present invention, which is designed for front-mounted installation.

[0077] As in Figure 14 As shown, the housing box is first lifted diagonally and pushed into a recess in the on-site wooden lintel. The housing box is then positioned horizontally over the guide rails 50 (see Figure 15 ) and then lowered onto the guide rails 50.

[0078] A fastening tab 52 of the guide rail 50 is inserted into a guide profile 84 of the housing box and at the same time a guide slide of the guide profile 84 is inserted into the guide rail 50 ( Figure 15 After positioning the housing box, the fastening tab 52 is pushed upward toward the housing box, and a shading element guide 56 is inserted into the guide rail 50. The shading device 100, 102 is a self-supporting system. This means that the housing box is supported by the guide rails 50 themselves, thus ensuring facade-friendly installation.

[0079] The fastening tab 52 is located in the guide rail 50 and can be moved up and down between two end positions. This provides the advantage that when placing the housing box on the mounted guides 50, no additional building headroom is required to lift the housing box by the height of the fastening tab 52 and then place it over a guide profile chamber 84. The fastening tab 52 is initially retracted to a protruding minimum dimension and is then pushed up once the box is in place. This reduces the required niche height.

[0080] The fastening tab 52 is guided in a guide profile chamber 84 and can be moved up and down. The lower end stop can be achieved by a blind rivet nut, by punching a recess in the tab. In addition, the fastening tab 52 has a contour 53, namely an inward bend, which ensures that the inner guide can only be closed during assembly when the tab has been fully pushed up (Poka-Yoke). It also serves as a safeguard to prevent the fastening tab 52 from slipping down once the guide is fully assembled (closed inner guide).

[0081] Independently of this or in conjunction with this, there is the option of installing the guides in a recess during lintel installation. For this purpose, a specific spacer for the guide rail 50, namely guide adjustment units, was developed (see Fig. Figures 19 to 24 ).

[0082] These guide adjustment units are made of plastic, for example, and are mounted in the guide rail 50. Thanks to these adjustment units, the installer has the option of adjusting the guide depth, allowing him to correct deviations in the depth of the facade recess (see. Figures 23 and 24 ).

[0083] The adjustment units comprise two different elements, namely a slide 90 and an adjustment unit, such as an adjustment screw 96. Slide 90 and adjustment screw 96 are screwed together by a thread. To achieve high weather resistance, the guide adjustment units can be made of, for example, polyoxymethylene (copolymer).

[0084] In the Figures 23 and 24The maximum and minimum width of the guide adjustment unit is shown as an example. The front of the guide rail 50 should be flush with the facade reveal. Accordingly, the gap between the back of the guide and the groove base must be bridged. The guide adjustment unit can, for example, allow a gap bridging of approximately 7 mm.

[0085] To install the guide adjustment unit, first position the guide rail 50 without the adjustment unit in the niche, and mark and drill at least one mounting hole. The guide adjustment unit is then mounted into the guide rail 50, and the guide is adjusted in depth. Once the depth is set, the guide adjustment unit can be firmly attached to the façade in the desired position, for example, using screws. The screws can be guided to the façade, for example, through the elongated holes of the adjustment screw 96. The elongated holes are arranged between the spokes of the adjustment screw 96.

[0086] The carriages 90 can be clamped to the guide rails 50 by means of a rotationally secured connection formed between the carriage 90 and the guide rail 50. This rotationally secured connection comprises lateral clamping elements 92 arranged on the carriage 90, which can be clamped between lateral guideways of the guide rail 50. As shown in Figure 19 As shown, the slides 90 can, for example, be clipped from the outside into an open guide chamber of the guide rail 50 thanks to two lateral spring elements. Once mounted, the guide adjustment unit can still be moved vertically in the guide rail 50, but the clamping force of the lateral spring elements and the resulting friction provide sufficient self-locking to prevent the guide adjustment unit from falling downwards on its own.

[0087] In addition, the carriage 90 has a locking element 94 for vertical positioning within the guide rail 50, which can be positively secured in a locking recess 58 arranged on the guide rail 50. The unit can thus be locked into the cutout for the guide fastening screws, for example, via a locking connection, such as a clip.

[0088] The adjusting screw 96 has a circular cylinder jacket section with a thread, a cylinder cover surface which has gripping elements arranged on the outer circumference of the cylinder cover surface, namely a knurling, and an adjustment recess arranged centrally in the cylinder jacket section, wherein the adjustment recess 97 is designed to receive a drive element of a tool, for example a drive head of a screwdriver, and is in operative connection with the cylinder jacket section.

[0089] An opening is provided in the guide rail 50, which enables adjustment 97 by turning the adjustment unit 96 using a tool (see. Figure 20 ).

[0090] The adjusting screw 96 allows for coarse adjustment using the gripping elements arranged on the outer circumference and fine adjustment using the central adjustment recess 97. The depth dimensions can thus be preset manually using the external toothing of the adjusting screw 96. If the guide rail 50 is inserted into the groove recess, the depth can be finely adjusted from the inside, for example, using a hexagon socket. LIST OF REFERENCE SYMBOLS
