Description

Technical field

The invention relates to a roller shutter device with a roller shutter shaft, on the optional a roller shutter curtain can be rolled up and unrolled again for a clear view to ensure a wall light opening closure or the wall light opening closure to shade and / or protect against the weather.

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 a roller shutter curtain usually composed of roller shutter bars on the one hand as well as slat blinds, on the other hand, which have a large number of flat slats, which are usually adjustable with respect to their inclination to a to ensure variable shading. Both slat blinds and roller shutters are can also be used for facades that are essentially glazed over the entire width, because slat blinds and roller shutters can be stowed in boxes above the windows are arranged. Compared to the slat blinds, roller shutters offer Advantages in terms of weather protection, burglary protection and Lifespan. Compared to shutters, however, roller shutters show - as by the way Louvre blinds also - disadvantages because their assembly is more complex and in the area the roller shutter boxes have comparatively poor heat and sound insulation consists.

Presentation of the invention

The object of the invention is to provide a roller shutter device that is comparatively is easy to install 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 shutter device for a wall light opening closure, that separates an exterior from an interior and with one rigidly in one Wall light opening frame is provided, a roller shutter shaft. The Roller shutter device further has a frame widening element with a flat Panel section (i.e. a flat panel-shaped section) that forms part of a frame widening of the frame. The roller shutter shaft is in the outside space in front of the Plate section arranged and attached to the frame widening element that a Roller shutter curtain can be rolled up onto the roller shutter shaft and again from the Roller shutter shaft can be unrolled.

The information "outside" and "inside" are in relation to the wall light opening understand in which the frame and the roller shutter device are to be arranged. The Masonry opening can be formed in a building envelope, and the masonry opening termination can in particular a window, a door or a gate of the Be building, in the wall of which the wall light opening is formed. The through The interior of the building defined by 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.

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. For the installation of the window frames are the wall light openings usually with prepared frame enclosures provided, which are also called frame extensions. The window frames are typically inserted into these in such a way that the Window frames are arranged flush with the frame extensions.

So far, in the case of a roller shutter device for a window, typically the Roller shutter shaft surrounding roller shutter box either on the window frame or placed on a frame widening part of the same. Because such a roller shutter box significantly poorer properties with regard to heat and sound insulation has as a window frame and a frame widening, affects the roller shutter box the insulation properties of the entire wall opening opening. In contrast, the roller shutter device according to the invention no separate roller shutter box on the frame or the frame extension must be put on. The roller shutter device is rather in the Frame broadening integrated, i.e. it is an integral part of it. It is no longer necessary in an area of the wall light opening instead of the well-insulating one Frame widening a roller shutter box with poor insulation use. Instead, the roller shutter shaft in front of the panel section is one Frame widening element arranged, the panel part being part of the frame widening with good insulation properties.

The frame widening element, in front of the panel section 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. As alternative however, the frame widening element can do this in addition to the flat plate section have other 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 shutter device on the frame widening element or be trained for other purposes.

The panel section is preferably in a roller shutter device according to the invention 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 section of the frame widening element in the Is essentially the same thickness as the window frame. When aligned Outside and the same thickness are also the inside of the window frame and the plate portion of the frame widening element in alignment with each other arranged. The window frame and the panel section can be flush with each other then be arranged so that they have a continuous wall with the same Define thickness. In this case the insulation properties are along this wall essentially equally good everywhere.

A roller shutter device according to the invention can, in addition to the roller shutter shaft and the Frame widening element further have a flat outer wall element, the on the plate part of the frame widening element opposite side the roller shutter shaft essentially parallel to the plate section of the frame widening element arranged and connected to it such that the Panel section at least a part of the inner wall and the outer wall element at least part of the outer wall of a surrounding the roller shutter shaft Define the roller shutter housing. The terms "inside" and "outside" are again to be understood in relation to the wall light opening in which the Roller shutter 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 entire outer wall may be formed solely by the outer wall element. The roller shutter shaft (and in its rolled-up state also the roller shutter curtain) are in arranged a roller shutter housing that is fixed to the frame extension element is attached, the housing inner wall through the plate part of the frame widening element and the housing outer wall through the outer wall element is formed. As an alternative, the inner and / or the outer wall can still have further wall elements.

In addition to the plate section of the frame widening element, this can also be done External wall element or even the entire roller shutter housing as an integral Be formed part of the frame widening element. The roller shutter housing and the frame widening element preferably together form one only assembly unit that can be installed as a whole in the wall light opening.

In addition to the roller shutter shaft, other components of the roller shutter device, such as. the gearbox for driving the roller shutter shaft - in Roller shutter housing arranged. You can then already in the manufacturing facility to be assembled. It is also in the case of a roller shutter device according to the invention - in contrast to previously conventional roller shutter devices - no longer required, Details for the roller shutter device (so-called lintel details) in the lintel of the Form the wall light opening. So far, such lintel details - e.g. Gearbox niches for those driven by crank, belt hoist, chain hoist or motor Roller shutter shaft gearbox - to be trained in the lintel on site, resulted in considerable additional effort. Due to the arrangement of the roller shutter shaft together with the gearbox in one as an integral part of a frame extension trained roller shutter housing can have a minimum installation height of the entire Roller shutter device can be reached. This installation height is only just high enough as it is due to the diameter of the roller shutter in its rolled up condition is absolutely necessary.

The formation of the housing as an integral part of a frame extension also proves to be advantageous in the case of a slat blind device.

According to a further preferred embodiment of the invention, a Roller shutter 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 roller shutter curtain can be rolled up on them. The roller shutter device is characterized by the fact that it continues a plurality of insulation bodies includes that can be dismantled in the roller shutter housing are formed between the two housing walls. The insulation bodies are further trained such that - if they are installed in the roller shutter housing, the Rolling up the roller shutter curtain on the roller shutter shaft and unrolling the Do not obstruct the roller shutter curtain from the roller shutter shaft. Because of the disassembly the insulation body is on the one hand the access to the roller shutter shaft and which ensures this driving gear, which is particularly for service purposes is advantageous. On the other hand, the insulation body can still be a good one Isolation of the provided with such a shutter 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 installed roller shutter shaft must be used.

The insulation bodies are preferably designed in such a way that they are arranged can be installed in the roller shutter housing, in which, with the exception of one Area whose width corresponds to the width of the roller shutter curtain, essentially fill the entire space in the roller shutter housing. This will be an optimal one Isolation of the wall light opening closure provided with such a roller shutter device reached. The width of the roller shutter curtain The corresponding area in the roller shutter housing must be used to roll up the roller shutter curtain be kept clear on the roller shutter shaft and therefore cannot be used Insulation bodies are filled. On the other hand, the entire remaining space in the Interior of the roller shutter housing that is not different from other components of the roller shutter device is taken, be filled with insulation bodies. Your Removability enables access to all in To create roller shutter housing arranged components.

Furthermore, the insulation body can be designed such that at least one insulation body can be installed in an arrangement in the roller shutter housing in which it is a Part of the reveal (i.e. a lateral inner surface that delimits the opening in the wall) forms the wall light opening and guides the roller shutter armor to the side. The movability the roller shutter bars in the longitudinal direction is then through this optionally removable insulation body (also as reveal body designated) limited, which forms a part of the reveal. In the roller shutter housing thus the roller shutter curtain at least partially by this insulation or Reveal body guided laterally.

Such a roller shutter device with a demotable soffit, which the Roller shutter curtain leads laterally in the roller shutter housing, further preferably comprises one roller shutter curtain that can be rolled up and rolled off the roller shutter shaft, which is composed of a multitude of roller shutter slats, which in Longitudinal direction (i.e. transverse to the longitudinal direction or to the roll-roll 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 must be guided laterally in order to prevent undesirable displacements To prevent roller shutter bars from facing each other. In the area of the roller shutter housing can complete the required cornering by one of the above removable soffit body are guaranteed. A roller shutter curtain with Rolling shutter slats that can be moved in the longitudinal direction of the bar is essential easier and cheaper to manufacture than a roller shutter curtain, its rods are connected to one another by means of bands, since such bands are completely dispensed with can be. The rods can e.g. made of aluminum profiles with one be designed uniform cross-sectional profile, these rods having a cross-sectional shape in such a way that they are mutually mutually transverse to the longitudinal direction of the bar can be attached. However, you can also use other suitable materials such as Be made of wood or PVC. Due to the mutual displacement of the bars can also be used to easily replace individual rods of the tank become.

According to a further preferred variant of the invention, a roller shutter device one having at least one inner wall and one outer wall Roller shutter housing, a roller shutter curtain and a roller shutter shaft on Roller shutter housing attached and so between the inner and outer wall is arranged that the roller shutter curtain can be rolled up on and off of it can be unrolled. The roller shutter device further has at least one hold-down element that is firmly attached to the roller shutter housing. This hold-down element is arranged in such a way that - if the roller shutter curtain essentially of the roller shutter shaft is unrolled - a stop of the roller shutter curtain in such a way that It can be brought down that the roller shutter armor prevents it from being pushed up is secured upwards. The anti-lift device created for the Roller shutter curtain is particularly useful for preventing burglaries. The stop can e.g. the top edge (i.e. the top face) of the Roller shutter curtain or the upper edge of one or more hanging pieces on which the roller shutter curtain is suspended .. However, the stop can also comprise one or more stop elements which in the region of the upper end of the Roller shutter curtain are firmly attached to this. The stop is thus in both cases in the area of the upper end of the roller shutter curtain. The Hold-down element can e.g. be angular or hook-shaped, that if the stop is located below it, it is not on the hold-down element can be pushed upwards. Preferably, the roller shutter shaft and that Hold-down element already in a manufacturing facility, e.g. a window factory, on Roller shutter housing attached, as a rule in such a manufacturing facility Tighter assembly tolerances can be maintained than on a construction site. Out for the same reason, the roller shutter curtain, including the stop, can already be in be installed on the roller shutter shaft in the factory.

The anti-lift device for the roller shutter curtain also proves to be effective regardless of the roller shutter shaft attached to a frame extension part or the removable insulation bodies as advantageous.

According to this variant of the invention, the roller shutter curtain is preferably in the area its upper end by means of resilient suspension elements on the Roller shutter shaft suspended that if after rolling the shutter shutter from the roller shutter shaft continues to operate the roller shutter shaft in the unwinding direction (i.e. by their Axis), the upper end area of the roller shutter curtain from the Roller shutter shaft is moved away, so that the stop automatically under the hold-down element brought. The springy suspension elements are wider preferably designed and arranged in such a way that if afterwards the roller shutter is operated in the winding direction (i.e. rotated about its axis), the upper one End region of the roller shutter curtain is moved towards the roller shutter shaft in such a way that the Stop is automatically brought out from under the hold-down element, whereupon the Roller shutter curtain by further actuation of the roller shutter shaft in the winding direction this can be rolled up. In this way, it becomes an extremely simple and Functionally reliable automatic push-up protection for the roller shutter curtain created. Suitable suspension elements for this purpose are e.g. Leaf spring elements made of steel or other suitable materials.

A roller shutter device for a wall light opening closure according to one Another preferred variant of the invention has a roller shutter shaft, a optionally rollable onto and off the roller shutter shaft Roller shutter curtain and at least one guide rail for lateral guidance of the Roller shutter curtain on while rolling up and down. The guide rail is in one Groove arranged in a soffit (i.e. a side, the wall light opening limiting inner surface) of the wall light opening is formed. The groove either trained in the original reveal of the masonry opening in the shell or it can be formed in a reveal element (e.g. a reveal strip) be inserted in the original wall light opening and then its Reveal defines. In the case of a groove formed in a reveal element for the The reveal element together with the guide rail can also be a guide rail as a ready-to-install element in a manufacturing facility distant from the construction site are prefabricated, which means the installation of the roller shutter device in the wall light opening is further simplified. By arranging the guide rail in one Reveal groove, the guide rail is covered and thus against prying open protected for burglary purposes. On the hitherto used on the reveal attached guide rails can be dispensed with, thereby protecting against burglary is improved. In addition, any spacer sleeves or others Fasteners are dispensed with, which 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 Arrangement of guide rails in reveal grooves not mandatory in the Connection with the roller shutter shaft attached to a frame extension part or the removable insulation bodies or the anti-lift device for the roller shutter curtain must be used.

The arrangement of guide rails in reveal grooves also proves as advantageous in the case of a slat blind device.

The guide rail arranged in the reveal groove can also be parallel to the Reveal surface arranged and lying on this plate section (i.e. one plate-shaped section) may be provided, which is dimensioned and designed such that on the outside of the wall light opening beyond the edge of the reveal protrudes and forms a cover for an exterior plaster that is in the area of Apply soffit to 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 of the invention, one comprises Roller shutter device has at least one inner wall and one outer wall having roller shutter housing, one attached to the roller shutter housing and roller shutter shaft arranged between the inner and outer wall of the Roller shutter curtain can be rolled up, and one on the underside of the roller shutter housing bottom view panel to be arranged. The bottom view panel is a flexible, flexible unit educated. Due to the possibility of flexible bending of the bottom panel a simple removal and reattachment of the bottom cover on Roller shutter housing enables. This can e.g. for insertion in or for removal be bent from a form-fitting holder into a form in which the Form fit is avoidable. The possibility of optionally detachable attachment the bottom view panel on the roller shutter housing ensures access to the Roller shutter housing from below, which is particularly desirable for service purposes is. Compared to the previously used bottom view panels, which e.g. from a Rigid aluminum profile made and using an elaborate holding device the underside of a roller shutter housing are optionally detachably attached a flexible, flexible underside panel extremely cost-effective. The bottom view panel according to this embodiment of the invention e.g. designed as a flexible tarpaulin be made of fabric or foil material. But it can also be from one Plurality of rigid individual parts that are flexible against each other are movably connected.

This aspect of the invention also proves to be independent of the one Frame extension part attached roller shutter shaft or the removable Insulation bodies or the anti-lift device for the roller shutter curtain or the in a soffit groove arranged guide rail as advantageous.

A roller shutter shaft with a flexible, flexible underside panel can also be one Roll up curtain armor that can be rolled up onto the roller shutter shaft comprise a large number is composed of roller shutter bars, the bottom view panel also made is composed of a plurality of roller shutter bars that form the roller shutter bars of the roller shutter curtain are identical. This creates the opportunity individual roller shutter rods of the bottom view panel as replacement rods for the actual one To use roller shutter curtain. The underside panel can be used in particular according to Art made a roller shutter armor section corresponding to the roller shutter curtain his. Both the roller shutter bars of the roller shutter curtain and the are preferably Roller shutter slats of the lower view panel each in the longitudinal direction of the bar with respect to each other freely movable. This will replace bars of the roller shutter curtain with Relieved bars of the lower view panel.

Preferably, a roller shutter device according to the invention with a Roller shutter shaft and a frame extension element with a flat panel 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 includes the roller shutter shaft and the frame widening element, whereupon in a second step the assembly unit is transported to the building and then in a third step the assembly unit as a whole into the wall light opening is installed. Thus, one becomes essential in the manufacturing workshop ready-to-install assembly unit. Attaching the roller shutter shaft on Frame widening element is much easier and in the manufacturing facility Can be carried out with greater precision than on the construction site. Preferably in the Manufacturing facility also attached the roller shutter curtain to the roller shutter shaft and rolled up on this. Advantageously, further components of the Roller shutter device - if there is one - already in the manufacturing facility the roller shutter device, e.g. a roller shutter housing, a Hold-down element for a push-up protection, insulation body, etc.

From the following detailed description and the entirety of the claims there are further advantageous embodiments and combinations of features of the Invention.

Ways of Carrying Out the Invention

1-3 is in a wall light opening for a Windows arranged, which is formed in a building wall. In the shell, the Light opening in the building wall above through a lintel 2, laterally through two reveals 4 and bounded below by a window parapet (not shown). In The wall light opening is a window that, among other things, a rigid in the Wall light opening arranged window frame 10, which has a glass plate 12 surrounds. The glass plate 12 defines the window level, and the window separates in Area of the wall light opening the building interior 6 of which the building surrounding exterior space 8.

The roller shutter device comprises a roller shutter shaft 20, a roller shutter armor 30, and a roller shutter housing 40 in which the roller shutter shaft 20 and in its rolled up State of the roller shutter curtain 30 are 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.

In the reveal surface of this reveal strip 54, a groove 58 is formed, which is in the Extends substantially over the entire height of the reveal bar 54. In this groove 58 a guide rail 50 made of an aluminum profile is arranged, which the lateral guidance of the roller shutter curtain 30 in the area below the roller shutter housing 40 serves. The arrangement of the guide rail 50 in the groove 58 is the Guide rail 50 covered and thereby against a prying open for the purpose Burglary protected.
