Description

Technical field

The invention relates to a roller shutter device with a roller shutter shaft, on the optionally a roll screen armor can be rolled up and unrolled again for a clear view to ensure through a wall light opening closure or the To shade the opening of the wall light and / or to protect it from the weather protect.

State of the art

For shading wall light openings, especially windows Window shutters that can be swung outwards have been known since ancient times. In closed Condition they protect the windows reliably from light, weather influences and also against burglaries. However, shutters are often considered to be distracting in terms of Aesthetics of a house facade are felt and are also due to their space requirements cannot be used for large glazed facades.

Roller shutters have also been known for a long time for shading windows. in the Connection with the present description and the claims A roller shutter is understood to mean any rollable closure that points you to an im Rolling screen armor that can be rolled up essentially horizontally arranged having. A roller shutter can in particular be a roller shutter or a slat blind (also known as a roller blind). The shutter of a roller shutter (Roller shutter curtain) is composed of a large number of roller shutter slats, during the armor of a slat blind made of a multitude of flat slats is composed, which is generally adjustable with respect to its inclination to ensure variable shading. Both slat blinds as well Roller shutters can also be used for facades, which essentially cover the whole Width are glazed because slat blinds and roller shutters can be stowed in boxes which are arranged above the windows.

Compared to shutters, roller shutters have - both shutters as well Slat blind disadvantages because their assembly is more complex and in the area of Roller shutter boxes have a comparatively poor heat and sound insulation.

Presentation of the invention

The object of the invention is to provide a roller shutter device, the is comparatively easy to assemble and has good insulation properties.

The solution to the problem is defined by the features of claim 1. According to the invention has a roller blind device for a wall light opening closure, that separates an outside space from an inside space and with a rigid inside a wall light opening to be arranged frame is provided, a roller shutter shaft on. The roller blind device also has a frame widening element a flat plate section (i.e. a flat plate-shaped section) which is part of a Frame broadening for the frame is. The roller shutter shaft is in the outside space arranged in front of the panel section and attached to the frame widening element, that a roll screen armor can be rolled up onto the roll screen shaft and can be unrolled again from the roller shutter shaft.

The information "outside" and "inside" are in relation to the wall light opening understand in which the frame and the roller blind device are to be arranged. The wall light opening can be formed in a building envelope. The one The interior of the building defined as such a wall light opening closure is then the interior of the building and the corresponding outside space is the space around the building around. The opening in the wall light can in particular be a window or a door or be a gate of the building, in the wall of which the wall light opening is formed is. The frame to be rigidly arranged in the wall light opening is then corresponding a window, door or gate frame.

Nowadays it is common to have window units with window frames and one or ready to assemble several window sashes in window factories. On the site the window frames with or without sash into the wall light openings (also called window recesses) installed.

Previously prepared frame extensions were used for the installation of the window frames (also known as frame enclosures) in the wall light openings used. The window frames were then typically used in the frame extensions used in such a way that the window frames are flush with the frame extensions were arranged abruptly. In the case of a roller shutter device for a The window then usually became a roller shutter box surrounding the roller shutter shaft either on the window frame or on a frame extension part (i.e. a part of the frame extension for the window frame). Because one Roller shutter box significantly worse properties in terms of heat and Has sound insulation as a window frame and a frame widening, the roller shutter box affected the insulation properties of the whole Wall light opening statements.

In contrast to this, the roller shutter device according to the invention has none separate roller shutter box more on the frame or the frame widening must be put on. The roller shutter device is rather in the Integrated frame extension, i.e. it is designed as an integral part of it. It is no longer necessary to place the wall light in place of the well insulating frame widening a roller shutter box with bad Insulation ability to use. Instead, the roller shutter shaft is in front of the panel section arranged a frame widening element, the plate part the frame widening with good insulation properties.

The frame widening element, in front of which the roller shutter shaft is arranged is, can only consist of a flat, plate-shaped section and have no other lots. In this case, the frame widening element besides his record part no further parts. Alternatively, you can the frame widening element, however, in addition to the flat panel section Have lots. These can e.g. for fastening the frame extension element in the wall light opening, for attaching the roller shutter shaft or other components of the roller blind device on the frame widening element or be trained for other purposes.

By the plate section of the frame widening element on which the roller shutter shaft is appropriate as an integral part of the widening of the framework trained, the possibility is created, the roller shutter shaft already in one Manufacturing facility such as a window factory firmly on the frame widening element to attach and together with the frame extension as an assembly unit in the Install the wall light opening. This allows the assembly of the inventive Roller shutter device can be significantly simplified.

In a roller blind device according to the invention, the plate section is preferred of the frame widening element with its outside to the outside of the Frame aligned. In the case of a flat, defining a window level Window frames and a flat panel section is the panel section, though it is aligned with the window frame, also arranged parallel to the window plane. A uniform escape of the outside of the window frame and the Panel part of the frame widening is both in terms of aesthetics as well advantageous with regard to the insulation properties of the clearance opening.

It is further preferred that the plate part of the frame widening element with its inside is aligned with the inside of the frame. The one from the Frame widening element and the part of the wall opening opening formed in the frame is then flush-fitted on the inside. In contrast to stood in the case of the usual wall light opening closures, with one Roller shutters were provided on the inside of the wall opening openings Roller shutter boxes in front.

In the case of a roller blind device according to the invention, in which both Outside of the plate section of the frame widening element to the outside of the frame and the inside of the plate section of the frame widening element are aligned with the inside of the frame, the panel section of the frame widening element is essentially the same thickness as the frame. The frame and the panel section can then be flush with one another be arranged so that they have a continuous wall of constant thickness define. In this case the insulation properties along this wall are in Essentially equally good everywhere.

This is preferably the frame widening element and the roller shutter shaft having roller shutter device formed as an assembly unit, which as a whole in the wall light opening can be used. This makes it inexpensive and efficient enables industrial manufacture of the roller shutter device by being in one of production site distant from the construction site (i.e. to an assembly unit assembled) and then on the construction site as a whole into the wall light opening is used. The frame is also preferably part of this Assembly unit trained.

A roller shutter device according to the invention can in addition to the roller shutter shaft and the frame widening element further has a flat outer wall element, also as part of the assembly unit that can be inserted as a whole into the wall light opening formed and on the plate part of the frame widening element opposite side of the roller shutter shaft substantially parallel to Plate section of the frame widening element arranged and with this is connected that the plate section at least part of the inner wall and that Outer wall element at least part of the outer wall of the roller shutter shaft Define surrounding roller shutter housing. The designations "inside" and "Outside" are again to be understood in relation to the wall light opening in which the roller blind device is to be arranged. The entire inner wall of the roller shutter housing can only through the plate section of the frame widening element and / or the entire outer wall is formed solely by the outer wall element his. The roller shutter shaft (and in its rolled-up state also the roller shutter armor) are then arranged in a roller blind housing, which is fixed to the frame widening element is attached, the housing inner wall through the plate section of the frame widening element and the housing outer wall through the Outside wall element is formed. Alternatively, the interior and / or the outer wall have other wall elements. In addition to the record section of the Frame widening element can also be the outer wall element or even that entire roller shutter housing as an integral part of the frame extension element be trained.

In addition to the roller shutter shaft, other components of the Roller shutter device, such as the gearbox for driving the roller shutter shaft - formed as part of the assembly unit and arranged in the roller blind housing. she can then already be assembled in the manufacturing facility. It is also in the In the case of such a roller shutter device - in contrast to the previously usual Roller shutter devices - no longer required, details for the roller shutter device (so-called lintel details) in the lintel of the wall light opening. So far such crash details - e.g. Gear niches for by means of crank, belt pull, Chain hoist or motor driven roller shutter shaft gearbox - on site directly in the Fall are trained, which resulted in considerable additional effort. Due to the arrangement of the roller shutter shaft together with the gearbox in one as integral part of a frame extension trained roller shutter housing a minimum installation height of the entire roller blind device can be achieved. This installation height is only just as high as it is due to the diameter the roll screen armor in its rolled up condition is absolutely necessary.

According to a preferred embodiment of the invention, the comprises as an assembly unit trained roller shutter device further at least as part of Assembly unit trained reveal element, which after the insertion of the Assembly unit in the wall light opening a lot of the reveal (with the Roller shutter device provided) wall light opening forms. The assembly unit can even be designed such that after the installation of the assembly unit in the Wall light opening the entire reveal is made up of reveal elements, which as Part of the assembly unit are formed. That as part of the assembly unit trained reveal elements can also be used as insulation elements for the Wall light opening closure and / or as guide elements for lateral guidance of the roll screen armor.

According to a further preferred variant of the invention, the comprises as an assembly unit trained roller shutter device further at least as part of Assembly unit trained parapet element, which after the insertion of the Mounting unit in the wall light opening in the area of the parapet of the wall light opening is arranged. The parapet element can in particular be one in the outside area the window sill to be arranged or an indoor window sill the window ledge to be arranged in the wall light opening.

According to a further preferred embodiment of the invention, a Roller blind device with at least one inner wall and one outer wall having roller shutter housing and a roller shutter shaft provided on Roller shutter housing attached and so between the inner and outer wall is arranged that a roll screen armor can be rolled up on them. The roller shutter device is characterized by the fact that it continues a plurality of insulation bodies includes, which can be dismantled in the roller shutter housing are formed between the two housing walls. The insulation body are further designed in such a way that - if they are installed in the roller blind housing are, rolling up the roll screen armor onto the roll screen shaft and rolling off of the roller shutter armor from the roller shutter shaft. Because of the disassembly the insulation body is on the one hand access to the roller shutter shaft and to which this driving gear ensures what especially for Service is advantageous. On the other hand, the insulation body can still be used good insulation of those provided with such a roller blind device Wall light opening completion can be achieved. It makes sense that this aspect the invention is not mandatory in connection with that on a frame widening part attached roller shutter shaft must be used. Of course but also the optionally removable insulation body as part of the above, can be used as a whole in the wall light opening Assembly unit be formed.

The insulation bodies are preferably designed in such a way that they are arranged can be mounted in the roller shutter housing, in which they except one Area whose width corresponds to the width of the roll screen armor, essentially fill the entire space in the roller shutter housing. This will make one optimal insulation of the wall light opening closure provided with such a roller blind device reached. The width of the width of the The area in the roller shutter housing corresponding to the roller shutter armor must be Rolling up the roll screen armor on the roll screen shaft are kept clear and can therefore not be filled with insulation bodies. On the other hand, the whole remaining space in the interior of the roller shutter housing that is not by others Components of the roller shutter device is taken with insulation bodies be replenished. The fact that it can be removed enables it to be removed if necessary Access to all components arranged in the roller shutter housing create.

Furthermore, the insulation body can be designed such that at least one insulation body can be mounted in the roller shutter housing in an arrangement in which it a part of the reveal (i.e. a side wall that delimits the opening in the wall light Inner surface) of the wall light opening and guides the roll screen armor to the side. in the In the case of elements of the roller shutter curtain that can be moved in the horizontal direction the displaceability of these elements is then possible by the optionally removable Isolation body (also called soffit body) limited, the one Batch of the reveal. The roll screen armor is thus in the roll screen housing at least partially guided laterally through this isolation or soffit body.

Such a roller blind device with a demotable reveal part, which leads the roll screen armor in the roll screen housing laterally, in particular one roller shutter curtain that can be rolled up and rolled off the roller shutter shaft comprise, which is composed of a plurality of roller shutter bars, in the longitudinal direction (i.e. transverse to the longitudinal direction or to the roll-unroll direction of the roller shutter curtain) can be moved freely (i.e. unlimited) with respect to each other. It it goes without saying that such a roller shutter curtain is essentially on its entire roll-up and roll-off distance as well as rolled up on the Roller shutter shaft (i.e. the roller shutter shaft) must be guided laterally to prevent unwanted To prevent displacements of the roller shutter slats in relation to each other. In the area of Roller shutter housing (i.e. the roller shutter housing) can be the required Lateral guide completely removable by one of the above Reveal body can be guaranteed. A roller shutter curtain with facing each other Longitudinal sliding bar shutter slats is much easier and Can be manufactured more cost-effectively than a roller shutter curtain with side locking devices in In the form of ribbons that connect the rods together, or in the form of Stops and counterstops on adjacent bars. The rods can e.g. be made of aluminum profiles with a uniform cross-sectional profile, these rods having a cross-sectional shape such that they are transverse to the Rod longitudinal direction are mutually attachable. But you can also choose from other suitable materials such as Be made of wood or PVC. Through the mutual displacement of the bars can further be a simple replacement of individual rods of the tank are made possible.

A roller blind device for a wall light opening closure according to one Another preferred variant of the invention has a roller shutter shaft, one optional rollable on the roll screen shaft and rollable from this roll screen armor and at least one guide rail for lateral guidance of the Rolling screen armor while rolling up and down. The guide rail is with a guide groove, which in a reveal (i.e. a lateral, the Wall light opening bounding inner surface) of the wall light opening is arranged. The guide groove can either be in the original reveal of the wall light opening can be arranged in the shell, or it can be in a reveal element (e.g. a soffit) arranged in the original wall light opening is used and then defines its reveal. In the case of a groove that is in one Reveal element is formed, which as part of a whole in the Wall light opening insertable assembly unit is formed, the Guide rail can also be formed as part of the assembly unit. Through the Arrangement of the guide rail in a reveal (i.e. in one in the reveal surface trained recess) is the guide rail at least partially arranged concealed by the reveal and thereby against prying open to Protected against burglary. On the previously used guide rails, that are completely placed on the reveal surface can be dispensed with. This improves burglary protection. You can also use any spacer sleeves or other fasteners that were previously required to the guide rails through insulation elements resting on the reveal surfaces to be firmly attached to the reveal. It is obvious that the Aspect of the arrangement of the guide groove in a reveal not necessarily in the Connection with that attached to a frame widening part Roller shutter shaft or the removable insulation body must be used.

The guide rail with the guide groove arranged in the reveal can continue with a surface arranged parallel to and lying on the reveal surface Plate section (i.e. a plate-shaped section) which are dimensioned in this way and is designed to be on the outside of the wall light opening over the edge protrudes beyond the reveal and forms a cover for an exterior plaster that in the area of the reveal on the outside of the wall in which the Wall light opening is formed. This will plaster the wall in which the wall light opening is formed, simplified.

According to a further preferred embodiment variant of the invention, the Guide rail with the guide groove arranged in the reveal as a hollow profile formed, which has a first hollow profile outside, in which the guide groove is formed, wherein this first hollow profile outside a lot of Reveal surface forms. The hollow profile has a second hollow profile outside perpendicular to the first outside of the hollow section and in relation to the opening in the wall light is arranged on the outside outside of the first hollow profile. The second Hollow profile outside has a flat surface which is designed such that on this at the construction site (after installing the roller shutter device together with the guide rail into the wall light opening) an external insulation and / or a Exterior plaster can be applied. The hollow profile can be part of a reveal element be formed, which is a further part designed as an insulation body includes. The entire reveal element comprising the hollow profile and the insulation body can in turn also be part of the previously mentioned as Assembly unit trained roller shutter device, which as a whole in the Wall light opening can be used.

Preferably, a roller blind device according to the invention with a Roller shutter shaft and a frame widening element with a flat plate section to be installed in a wall opening in a building - in a first step in a manufacturing facility distant from the building Frame extension element firmly attached and thus an assembly unit manufactured which the roller shutter shaft and the frame widening element includes. The assembly unit is then transported to the building in a second step and then in a third step the assembly unit as a whole into the Wall light opening installed. This means that an im Manufactured essentially ready-to-install assembly unit. Attaching the roller shutter shaft on the frame widening element is in the manufacturing facility much easier and more precise than on the construction site. Other connection details that had previously been made on the construction site, can now be made according to the invention in the manufacturing facility. Preferably, the roll screen armor is also attached to the in the manufacturing facility Roller shutter shaft attached and rolled up on this. In addition, will be advantageous other components of the roller shutter device - such as a roller shutter housing, Parapet elements, reveal elements, an anti-lift device, insulation body etc. - also already in the manufacturing facility on the trained as assembly unit Roller shutter device mounted.

Ways of Carrying Out the Invention

1-3 is a roller shutter device, which in a wall light opening for a window is arranged, which in a building wall is trained. In the shell, the light opening in the building wall is through through a lintel 2, laterally through two reveals 4 and below by one Window parapet (not shown) limited. There is a window in the wall light opening used, among other things, a rigidly arranged in the wall light opening Has window frame 10 which surrounds a glass plate 12. The glass plate 12 defines the window level and the window separates in the area of the wall light opening the building interior 6 from the exterior space 8 surrounding the building.

The roller shutter device comprises a roller shutter shaft (roller shutter shaft) 20, one Roller shutter curtain (roller shutter curtain) 30, and a roller shutter casing (roller shutter casing) 40, in which the roller shutter shaft 20 and in its rolled-up state the roller shutter curtain 30 are also arranged.

The inner wall of the roller shutter housing 40 arranged parallel to the window plane becomes through the top part of the window frame 10 and through a plate-shaped Frame widening element 42 formed, the part of a frame widening of Window frame 10 is. The one made of a well insulating plastic material Frame widening element 42 is the same thickness as the window frame 10. It is lying flush on the top of the window frame 10 and in alignment with this arranged in the wall light opening so that there is the gap between the top the window frame 10 and the underside of the lintel 2 completely filled and closes tightly. The outer wall of the roller shutter housing 40 is covered by a plate-shaped outer wall element 44 is formed, which is essentially the same Has length and width as the inner wall and is arranged parallel to this. On their two longitudinal ends are the outer wall element 44 and the frame widening element 42 each via a plate-shaped side wall element 46 connected with each other. These two side wall elements 46 form the side walls of the roller shutter housing 40. They are perpendicular to the window plane and parallel to the Surfaces of the reveal 4 are arranged and their main surfaces lie directly on them Reveal areas 4. Overall, the interior wall, the side walls and the Outside wall of the roller shutter housing 40, a closed frame with a rectangular plan and four vertical walls formed in the Masonry opening just below the bottom of lintel 2 and between the two Reveal surfaces 4 of the wall light opening is arranged.

The roller shutter shaft 20 is approximately in the middle between the inner wall and the Outside wall of the roller shutter housing 40 (i.e. in the outer space 8 in front of the frame widening element 42) arranged. It is parallel to the window plane and substantially horizontally arranged axis 22 rotatable, using suitable Storage and fastening means (not shown) on the side wall elements 46 and thus indirectly attached to the frame widening element 42. With others Variants of the invention can the roller shutter shaft by means of suitable bearings and holding means also be attached directly to the frame widening element. The roller shutter shaft 20 is via a gear 24 arranged in the roller shutter housing and a Intermediate shaft 26, which is formed by a in the frame widening element Bore is passed through, coupled to a manually operable crank 28. By rotating the crank 28 in one direction or the other, the roller shutter shaft can 20 are rotated in one direction or the other about their axis 22 roll up the roller shutter curtain 30 onto the roller shutter shaft 20 or roll it off. Furthermore, the roller shutter shaft 20 is in this way to the inner and outer wall of the roller shutter housing 40 and spaced from the underside of the lintel 2 that sufficient Space for a complete roll-up of the roller shutter curtain 30 on the Roller shutter shaft 20 is available.

The clearances in the roller shutter housing 40 between that in its rolled-up state space taken up by the roller shutter curtain 30 and the housing walls of the Roller shutter housings 40 are made with a plurality of three-dimensional, made of styrofoam manufactured insulation body (not shown) filled, this insulation body optionally removable in the roller shutter housing 40 are mounted. In assembled In the state, these insulation bodies form a gearbox recess, which the gearbox 24 completely encloses. This remains due to the fact that the insulation body can be removed Gear 24 still accessible for service and repair purposes.

The insulation bodies are designed such that they are inside the roller shutter housing 40 form a new reveal, which in comparison to the original reveal 4 the Masonry opening in the shell is shifted towards the middle of the masonry opening. The in the roller shutter housing 40 through the removable insulation or reveal body Reveal formed borders in the longitudinal direction of the roller shutter shaft 20 directly to the Side edge of the roller shutter curtain 30, so that the roller shutter curtain 30 through this Soffit is guided laterally.

The roller shutter curtain 30 is composed of a plurality of roller shutter slats 31, 32, 33 composed in the longitudinal direction (i.e. essentially parallel to the Roller shutter shaft 20) can be moved freely (i.e. indefinitely) with respect to one another. The Roller shutter curtain 30 is essentially along its entire winding and unwinding path and laterally in the rolled-up state on the roller shutter shaft 20. in the Roller shutter housing 40, this lateral guidance by the above described Reveals guaranteed from removable insulation bodies. Outside (i.e. below) of the roller shutter housing 40, the roller shutter armor is replaced by the following described guide rails 50 out. The roller shutter bars 31, 32, 33 are off Aluminum bar profiles made with a uniform cross-sectional profile. The Cross-sectional profile is designed such that it is on the upper edge of the roller shutter slats 31, 32, 33 a hook-shaped section and at the bottom an angular section forms, so that in each case the hook section of a roller shutter rod 32 in the corner section another roller shutter rod 31 arranged above this rod 32 can be suspended.

On the inside of the outer wall element 44 facing the roller shutter shaft 20 is a horizontally extending ledge 48 with an approximately angular one Cross section firmly attached. The cross section of Fig. 1 the vertical leg Corresponding plate section of this bar 48 is used to attach the bar 48 on Outer wall element 44, while that corresponding to the horizontal leg Panel part the actual holding down the Rolllatenpanzer 38 or with this connected suspension piece 38 is used. The bar 48 is opposite Roller shutter shaft 20 and arranged slightly below the same. It serves as Hold-down element 48 for holding down the roller shutter curtain 30 in its Roller shutter shaft 20 unrolled state and is part of a push-up protection for the Roller shutter curtain 30. The mounting position of the hold-down bar 48 on the outer wall element 44 is selected such that - when the roller shutter curtain 30 completely from the Roller shutter shaft 20 is unrolled - the upper edge of the roller shutter curtain 30 or top bar 31 slightly lower than the underside of hold-down bar 48 is arranged. At those points of the bar 48 which are in the longitudinal direction of the bar 48 are each opposite the leaf spring elements 36 described below in the horizontal plate section of the strip 48, recesses 49 in each case formed that the leaf spring elements 36 can be pushed into them.

The uppermost roller shutter rod 31 of the roller shutter armor 30 is by means of suspension pieces 38 and elongated leaf spring elements 36 suspended from the roller shutter shaft 20. A leaf spring element 36 and a suspension piece 38 are shown in Figures 1 and 2. On Longitudinal end of the leaf spring element 36 is fixed to the peripheral surface of the roller shutter shaft 20 attached. At its other longitudinal end a suspension piece 38 is attached, the is provided at its lower edge with a section which is angular in cross section, which is the same as the angular section at the lower edge of the roller shutter slats 31, 32, 33 is trained. As a result, the uppermost roller shutter rod 31 with its at the upper edge molded hook section on the angular section formed on the suspension piece 38 be attached.

In Fig. 1, the roller shutter curtain 30, the suspension piece 38 and that Leaf spring element 36 shown in solid lines in the position that immediately after the roller shutter armor 30 has completely rolled off the Roller shutter shaft 20 have reached. After reaching this position the Roller shutter shaft 20 actuated further in the rolling direction (i.e. rotated about its axis 22), so the top roller shutter rod 31 by the hanging piece 38 and Leaf spring element 36 pushed under the hold-down bar 48, which at the same time Leaf spring element 36 into the recess 49 formed in the hold-down bar 48 is pushed in until the position shown in broken lines in Fig. 1 is reached. In this position, the suspension piece 38 is immediately below the Underside of the hold-down bar 48 and the leaf spring element 36 in the area of Hold-down bar 48 arranged in the recess 49 .. A pushing up the Roller shutter curtain 30 is no longer possible in this position because of the hanging piece 38 abuts on the underside of the hold-down bar 48 and thus pushes it up would block.

If after reaching the position shown in broken lines in Fig. 1 the roller shutter shaft 20 is operated again in the winding direction, then the top one Roller shutter bar 31 and the suspension piece 38 first through the leaf spring element 36 pulled out from the hold-down bar 48 towards the roller shutter shaft 20, whereupon the roller shutter curtain 30 by a further actuation of the roller shutter shaft 20 in Rolling direction can be rolled up on this.

Overall, the roller shutter device shown in FIGS. 1-3, including the Push-up protection for the roller shutter curtain is extremely space-saving become. As shown in Fig. 1, the roller shutter device is dimensioned such that with the roller shutter curtain 30 completely unrolled from the roller shutter shaft, only the uppermost roller shutter rod 31 is partially arranged in the roller shutter housing. The Installation height of the entire roller shutter device is only just as high as it is due to the diameter of the roller shutter curtain in its rolled up condition is absolutely necessary. In the case of a roller shutter curtain, for the previously known Roller shutter devices require an installation height of approximately 30 cm, the required Shutter device according to the invention shown in Figures 1-3 only another installation height of about 18 cm.

Below the roller shutter housing 40 are 4 on the two reveal walls Wall light opening each a soffit 54 arranged, which the light width of the Reduce the opening of the wall light so that it is smaller than the length of the Roller shutter bars 31, 32, 33 defined width of the roller shutter curtain 30. The in the 3 shows a reveal bar 54 that extends in FIG vertical direction over the entire height between the parapet Wall light opening and the shutter housing 40. Your the middle of the wall light opening facing side surface defines the actual reveal in this height range or reveal surface of the wall light opening.

A recess is formed in the reveal surface of this reveal strip 54, which extends essentially over the entire height of the reveal bar 54. In this The recess is the U-shaped section of a profile made of an aluminum profile Guide rail 50 arranged such that that defined by the U-profile Guide groove 58 substantially completely in the in the soffit surface (Reveal surface) of the reveal bar 54 formed recess is. The guide groove 58 serves to guide the roller shutter curtain 30 laterally Area below the roller shutter housing 40. By the arrangement of the Guide rail 50 derat that the guide groove 58 in the reveal bar 54 or in whose recess is arranged, the guide rail 50 is covered and thereby protected against prying open for the purpose of burglary.

The guide rail 50 is further parallel to the reveal surface arranged and provided on this plate section 52, which are parallel extends to the reveal surface beyond the outer edge of the reveal strip 54. This A plate section 52 protruding beyond the outer edge of the reveal strip 54 forms one Final drawer 52 for an exterior plaster 56, which in the reveal area on the Outside of the wall is applied, in which the wall light opening is formed is.

In FIG. 4, another representation corresponding to FIG. 3 is another preferred one Embodiment variant of a roller shutter device according to the invention shown 1-3 in relation to the guide rail 150 different. The guide rail 150 is designed as a hollow profile, the first Has hollow profile outside 153, in which the guide groove 158 is formed, which the roller shutter bars 133 leads laterally. The first hollow profile outside 153 forms one Batch surface area.
