Description

The present invention relates to a mounting bracket for making a force transmitting connection between a window or door frame and a lintel, and a roller shutter box having such a mounting bracket.

Window and door frames (hereafter referred to as "frame") are to be fastened peripherally to the respective wall or building surrounding them. For the sake of better readability, the terms "wall" or "masonry" are used hereafter for any enclosure surrounding the frame, even if it is not made of masonry but of another material, such as e.g. Wood, should be made or if the enclosure is already part of a floor ceiling. The wall section above a window or door frame is referred to herein as a "camber" for easy distinction from other wall sections, including a supporting ceiling section or rim.

The attachment of the frame on the side and bottom side arranged masonry can usually be done directly, ie without the use of spacers. For this example, screws are driven from the frame inside through the frame in the surrounding masonry. A gap located between the frame and the masonry can be bridged for alignment and adjustment with narrow pieces of wood or similar spacers. The rest of the gap is closed with a construction foam. If a roller shutter box is arranged above the frame, the frame is conventionally attached to the roller shutter box, wherein the roller shutter box is in turn connected to an overlying lintel, which is usually poured as a concrete lintel on the shuttering box serving as shuttering in this case and in some variants, for example, in undercut ( Dovetail) grooves engages the top of the shutter box. The length of the roller shutter box is greater than the width of the underlying window or door opening, so that the roller shutter box rests with a corresponding projection on the side wall portions which define the building opening. However, such attachment of the frame loaded the largely made of insulating roller shutter box and not enough in many applications no longer meets the current requirements and building regulations. In addition, the requirement of attachment of the frame to the roller shutter box limits the freedom in choice of materials and design of the roller shutter box, especially in terms of optimized thermal insulation. The insulating material from which shutter boxes are typically made includes typical insulating materials known as EPS, XPS, mineral wool, rock wool, organic or inorganic polymer, or as commercially available under the tradenames Neopor or Styrodur.

As "roller shutter boxes" in the context of the present invention also external blind boxes or other box-shaped cavities are considered, which extend directly above window or door frames generally over the entire width, and the example, external blinds, blinds, shutters or other facilities, for example the sunscreen, and are made entirely or mainly of the above materials. The lambda value of the thermal conductivity of the insulating material from which the roller shutter boxes are made is generally below 0.04 W / (m · K).

As windows and doors in new buildings are designed to be increasingly taller and wider, and as climate change threatens higher peak wind speeds, building codes are becoming increasingly stringent in the affixing of window and door frames to the walls and ceilings surrounding the frames. This is true not only because of the often multi-glazed windows and doors, the glazing may have a weight of up to 30 kg / m ² , but above all because of acting on windows and doors wind loads, which increase with the size of windows and doors , Modern building materials with very good thermal insulation properties often have a large number of air pockets, so that a roller shutter box made of such a material may not have the required strength to absorb the forces acting on it.

A problem in this context is the fact that, among other things for the purpose of better thermal insulation and the masonry of modern buildings are often made of very filigree bricks or other fasteners for little mechanical support bidding material. If then also along the top of a wide window, the frame is insufficiently secured or has great play of movement, the anchors in the side walls are very quickly overloaded, causing it to breakouts of masonry or wall material on the sides of building openings can come.

The conventional attachment of the upper spar of window or door frame on a roller shutter box therefore does not meet the increased requirements.

It is therefore the object of the present invention to enable an improved non-positive connection between a window or door frame and a lintel in the case of roller shutters integrated below a lintel, without appreciable forces being introduced between the frame and the lintel over the heat-insulating material of the roller shutter box, which consists of the roller shutter box predominantly.

The problem is solved by a mounting bracket for producing a force-transmitting connection between a window or door frame and a lintel, wherein the mounting bracket has a connecting web, at one end of a frame-side connecting element and at the other end a wall-side connecting element is arranged, wherein the height dimension between the frame-side connecting element and the wall-side connecting element, measured between their sides facing a frame or a fall sides at least 10 cm, preferably at least 15 cm and in particular at least 20 cm.

The distance between the connection elements serves to bridge at least part of the height and preferably the entire height of a roller shutter box between the frame and the lintel.

By attaching the wall-side connection element to a lintel and the frame-side connection element to a frame forces acting on the frame can be initiated directly on the mounting bracket in the fall. As a result, an overload of the frame fastenings along the lateral wall sections of a building opening is avoided.

In a variant of the invention, the wall side is glued to a window or lintel.

Depending on the surface structure and flatness of the lower lintel surface, the adhesive layer may either be very thin (eg less than 1 mm thick, homogeneous adhesive layer for smooth, flat lintel surfaces) or deliberately as a thick adhesive layer (several mm to eg 2 cm). be performed, for which in particular a special, solid and stable mounting foam with high adhesive strength is suitable, the z. B. under the trade name Cosmopur 1716, 2-K-PUR adhesive is available.

In this case, the frame-side connection element and the wall-side connection element are spaced apart from one another such that at least part of a roller shutter box can be arranged between the frame-side connection element and the wall-side connection element. Since the forces acting on the window or the door are transmitted (in part) over the upper spar of the frame and the mounting bracket in the fall, the shutter box is hereby not, but at least considerably less burden than when using the roller shutter box as a force-transmitting connection element between the frame and camber.

In the present description, the terms "top", "bottom", "inside" and "outside" are used as they are defined in a built-in window.

The height dimension between the frame-side connection element and the wall-side connection element, measured between their sides facing a frame or a fall, can in the range of 100 cm to 50 cm, preferably in the range of 15 cm to 35 cm, and preferably in the range of 20 cm lie to 30 cm. In practice, the height of the mounting bracket is more or less than 25 to 30 cm and is generally adjusted to the height of the roller shutter box used.

So that the mounting bracket can be adapted to the height dimension of different roller shutter box, the height dimension of the mounting bracket can be adjustable in one embodiment. For example, the connecting web of the mounting bracket may be made in two or more parts, wherein the parts of the connecting web are detachably connected to each other in predetermined positions corresponding to predetermined height dimensions. The parts of the connecting web can u.a. be configured as U-profiles, wherein the U-profiles have at predetermined intervals recesses through which a fastening means can be performed so that the U-profiles can be detachably connected to each other in predetermined positions. The mounting bracket can then be used for roller shutter box with different height dimensions.

The upper and the lower connection element may each independently have a mounting flange, which may also be in the form of a mounting plate, which optionally has reinforcing beads. The flange can be created with its flat side to the lintel or the frame and attached to this, for example glued and / or screwed. Conveniently, the flange may have a corresponding number of holes for this purpose.

In one embodiment, at least the wall-side connection element is designed for bonding to the underside of a lintel, in particular designed, for example, as a horizontal flange.

For bonding, the flange can in particular have recesses and / or undercuts, penetrate into the adhesive and thus provide a particularly durable connection can. Furthermore, such a flange should have an area of at least 50 cm ^2, preferably at least 80 cm ² , from the lintel for an adhesive bond in plan view.

Located in the top of the frame to be fastened a matching recess, the frame-side flange can also be used in whole or in part in this recess, so that the connection between the frame and mounting bracket is designed as positive locking. A locking between the frame-side flange and the frame is also possible.

In one embodiment, the minimum distance between the flat sides of the flanges is selected such that a predetermined roller shutter box can be inserted precisely between the fittings, for which purpose recesses in the roller shutter box may also be provided or made.

It is also conceivable that a part of the upper spar of the window frame is embedded in the bottom of a roller shutter box, so that the mounting bracket does not necessarily and in all cases must bridge the entire height of the roller shutter box. Likewise, the top of the shutter box could have a recess in which a portion of a fall is received.

In another embodiment, the connection element or the flange may also extend substantially vertically and be designed for attachment to the inner surface of a window frame.

In one embodiment of the invention, the mounting bracket is formed in a side view, corresponding to a cross-sectional view through the bridged shutter box, Z-, C- or L-shaped. Other shapes or additions of Z-, C- or L-shape are conceivable, where it essentially depends on the basic shape of a vertical connecting web and a substantially horizontal lower leg with connecting elements at the upper end of the vertical leg, as well as the lower horizontal leg. In turn, the connection elements may take the form of legs or flanges, elbows, etc., thereby supplementing the basic shape of the "L" or "C" or (though less preferred) of the "Z" into correspondingly more complex or modified forms. In particular, the connection elements may be identical to the horizontal lower and / or upper horizontal webs of the L or C or Z shape.

This basic shape allows the arrangement of the mounting bracket with its vertical leg vertically along an inner side of a roller shutter box, wherein a lower leg of the Z, C or L shape below the roller shutter box from the inside out to the top Holm a frame extends there to be firmly connected to this. This takes into account the usually existing offset of the window frame relative to the inner surface of the roller shutter box to the outside, wherein the vertical leg of the mounting bracket can not extend correspondingly deep inside the shutter box because he would collide there with the wound roller shutter or the roller shutter shaft. Also at the top of the roller shutter box is provided along the top side an outward (C-shape) or inside (Z-shape) extending leg of the mounting bracket to improve the stability, again the C-shape is preferred over the Z-shape, because the upper leg is then covered by the shutter box and does not disturb the appearance of the fall or a ceiling of the room.

The horizontal legs, in particular the lower leg, may have a variably adjustable length. Accordingly, the relative location of a frame to be fastened relative to the camber in the horizontal direction within the wall opening and thus also relative to a located below the lintel shutter box can be adjusted.

For example, in one embodiment, a frame-side flange may be fastened continuously or discretely at various predetermined positions along the first leg, for example by means of a groove-and-groove connection.

The frictional connection between the wall-side connecting element of the mounting bracket and a fall may possibly be improved by the flat side of the wall-side flange has a profile, preferably in the form of pyramidal elevations, a waveform and / or in the form of thorn-like elevations. Through the profile, the friction between the wall-side flange and the camber can be increased. For thin flanges (plates), the profiling also serves to increase the stability

It is provided in one embodiment that the frame-side flange relative to the connection element in the direction of the wall-side connection element, d. H. is offset upwards. A projection located on a frame can thus engage in a depression between the frame-side flange and the frame-side connection element.

In one embodiment, the camber-engageable flat side of the wall-side flange and the frame-engageable flat side of the frame-side flange are substantially parallel to each other and substantially perpendicular to the tie bar.

The wall-side connecting element can be supported relative to the connecting web, for example with an angle plate. The angle plate stiffens the connection between the connecting element and the connecting web, so that overall the attachment between a fall and the wall-side connecting element is more resilient - especially against acting on the mounting bracket lateral forces and moments.

For the stable and substantially rigid connection between the vertical connecting web and one or both or horizontal legs, which have the connection elements, a corner reinforcement or a strut can be provided. In one embodiment, a framework knot consisting of metal strips welded together is provided for this purpose.

It is advantageous if at least the wall-side connecting web or flange terminates approximately flush with the upper side of the roller shutter box. In particular, when gluing such a flange then the top of the shutter box at least in the vicinity of the flange or even the entire surface are glued to the lower surface of a lintel, so that a secure and tight connection between the bottom of the lintel and the top of the roller shutter box results in but forces transmitted by wind loads mainly by the dimensionally stable compared to the shutter box mounting bracket and stronger deformations or loads of the roller shutter box can be prevented. However, for the connection of the top of the shutter box with the fall of the adhesive used for the connection of the flange may be replaced by another adhesive, by sealing tapes or by mounting foam, unless the top of the shutter box is not sufficiently close to the underside of the fall.

The mounting bracket can consist of several non-positively and positively connected to one another stable parts. For example, an upper connection element may be fastened to a lintel, which in turn is rigidly connectable to the remaining part of the mounting bracket, or a lower connection element is fixedly connected, for example, to an access flap of the roller shutter box and can be replaced with this from the roller shutter box and the remaining part of the shutter box Connection bracket removed and re-positively and preferably rigidly connected to these parts. Optionally, the inspection flap or a lower closure lid of the roller shutter box itself can be made of a sufficiently stable material that it simultaneously forms the lower connection element of the mounting bracket

The mounting bracket may also be an integral part of a roller shutter box, as also described below. The angle plate or a truss node are enclosed during foaming of the mold for the shutter box of the material of the shutter and make a secure connection with the mounting bracket. The connection elements remain accessible through the walls of the roller shutter box. Optionally, recesses in the walls of the roller shutter box may provide direct access to mounting holes in the fittings. These recesses can be closed after installation of the mounting bracket by dowels or plugs made of the material of the roller shutter box.

In one embodiment, the connecting web has a thermal separating element which thermally separates the wall-side connecting element and the frame-side connecting element. The thermal separating element may in particular also comprise the entire lower horizontal leg or parts thereof and / or the frame-side connecting element in order to avoid a thermal bridge between the frame-side connecting element and the inner space.

In one embodiment, the separating element extends over the lower leg up to the upper C-leg or wall-side connecting element, but does not include its leg or connecting element. In yet another embodiment, the entire connecting web consists of a poorly heat-conducting material.

In one embodiment, the thermal separator is made of a material having a specific thermal conductivity in the range of 0.001 W / (m * K) to 0.6 W / (m * K), preferably in the range of 0.02 W / (m * K ) to 0.3 W / (m * K), and more preferably in the range of 0.03 W / (m * K) to 0.18 W / (m * K). Materials with such a specific thermal conductivity are available with sufficient stability and prevent the formation of thermal bridges.

The thermal separating element may consist wholly or predominantly of a composite fiber.

Assuming sufficient stability, the mounting bracket can be made of a variety of materials and combinations thereof, such as, but not limited to, steel, plastic, GRP, aluminum, wood, wood composites, stabilized paperboard and cardboard, mineral fibers, and PVC mesh fabrics.

The present invention also relates to a roller shutter box made of insulating material, with an upper side, an at least partially open underside and an inner side, wherein the roller shutter box has at least one mounting bracket, in turn, a vertical connecting web, a horizontal connecting web with a frame-side connecting element on lower end of the connecting web and a wall-side connecting element at the upper end of the connecting web, wherein the connecting web extends between the top and bottom of the roller shutter box in such a way that the wall-side connecting element (4) with a lintel above the roller shutter box and the frame-side connecting element with a frame is connectable below the roller shutter box.

In general, the connecting web extends along the inside (10d) of the roller shutter box. However, if a roller blind or a sunshade on the inside of a window to be lowered from the shutter box, the outer and inner walls of the shutter box must swap their role, so that the connecting web would then run along the outside.

The mounting bracket may in particular be an integral part of a roller shutter box, as described in more detail below.

In one embodiment, the wall-side connection element on the upper side of the roller shutter box and the frame-side connection element can rest against the underside of the roller shutter box. The mounting bracket can thus at least partially surround the roller shutter box in such a way that the roller shutter box can be arranged precisely between the wall-side connection element and the frame-side connection element.

It is also expedient, if the mounting bracket is integrated into the roller shutter box such that at least the connecting web, preferably also one or both connecting elements, does not protrude from the outer surface of the roller shutter box. The roller shutter box and the integrated mounting bracket can thus be flush with the inner surface and preferably also the underside of the roller shutter box without protruding into the space, which is a subsequent processing of the inner wall, e.g. Wallpapering and painting, complicate.

The mounting bracket can be inserted, for example, during the manufacture of the roller shutter box before foaming in the mold for the roller shutter box, so that the mounting bracket is due to the foaming of the form an integral part of the roller shutter box.

The roller shutter box may for example also have additional recesses, which facilitate access to the connection elements. Such recesses can be closed after installation, for example, by appropriate dowels or plugs.

The Indian FIG. 1 shown in a perspective view mounting bracket 1, which also in the Figures 2 and 3 can be seen with further details is provided according to the present invention for producing a frictional connection between a window or door frame 14 and a lintel 15, the latter may also be formed by a ceiling portion (as in the Figures 2 . 4 and 5 shown). The mounting bracket 1 has a vertically extending connecting web 2. At one end of the connecting web 2, a frame-side connecting element 3 is arranged that extends approximately perpendicular to the connecting web 2 and has a flange 3a, with its lower flat side 5 on the upper Holm 14 is a frame and connect to this is.

This embodiment gives the mounting bracket substantially an L-shape. A wall-side connecting element 4 with a flange 4a for attachment and attachment to a lintel is located at the other end of the connecting web 2. The wall-side connecting element 4 extends in this embodiment relative to the vertical connecting web 2 only relatively little in the horizontal direction, so that the mounting bracket 1 appears in side view substantially as L-shaped. In particular, in further horizontally extending connecting elements 4 and flanges 4a, this L-shape is in a C-shape.

For attaching the mounting bracket 1 to a fall (in the FIG. 1 not shown), the wall-side flange 4 a is pressed with its upper flat side 6 to the underside of a lintel 15. By means of the bores 16 provided in the flange 4a, one screw can then be passed therethrough and screwed into the lintel, for example using a dowel.

The screwing can, unlike in FIG. 2 shown, obliquely into the ceiling or into a lintel 15 above the roller shutter box 100 from the inside of the roller shutter box. As far as the wall-side connecting element extends into the region above the cavity of the roller shutter box, screws or other fastening elements can also be introduced from the cavity of the roller shutter box through the upper wall into the lintel.

In order to increase the stability of the attachment, the wall-side flange 4 a passes over into an angle plate 7 which is angled downwards and which supports the wall-side flange 4 a on the connecting web 2.

The frame-side flange 3a is provided with a frame 14 (in FIG FIG. 2 and 3 shown) connectable. In the embodiment shown, the flange 3a is optionally suitable for gluing, screwing or mutual positive engagement with an upper spar of the frame. The facing a fall flat side 6 of the wall-side flange 4 a and the frame facing flat side 5 of the frame-side flange 3 a extend substantially parallel to each other and substantially perpendicular to the connecting web 2. Thus, the Bottom of the camber and the frame top, which also extend substantially perpendicular to the connecting web 2, are easily connected to the flanges 3a and 4a, respectively.

The frame-side connecting element 3, in particular its flange connected to the frame 3a and the wall-side connecting element 4 and thus also the interior behind the roller shutter box are thermally separated from each other, wherein the connecting web 2 for this purpose has a thermal separating element 9, each a part of the vertical L-leg and the lower L-leg. In this case, the thermal separating element 9 is produced, for example, predominantly from a composite fiber material having a specific thermal conductivity in the range from 0.02 W / (m * K) to 0.3 W / (m * K). The vertical leg 2 thus consists of an upper straight portion and formed as a thermal separating element 9 angle portion, which are joined together in the region 19, for example by means of a positive connection, preferably in an interference fit. Likewise, the connection element 3 is assembled at 20 by means of a corresponding connector. It is understood that the L-leg 2 including the angle section 9 together with the connection element 3 (and without or with the flange 3 a) in one piece of a poorly heat-conductive, but stable material, such as a glass fiber reinforced plastic (GRP), could be made in one piece

The thermal separating element 9 prevents the formation of a thermal bridge between the optionally attached to the outside of the upper frame spar flange 3a and the interior of the corresponding building.

The height dimension between the frame-side connecting element 3 and the wall-side connecting element 4, measured between the side facing a frame 14 and a fall 15 sides 5,6, is in the range of 20 cm to 35 cm, so above the frame 11 and below the lintel 15th a shutter box 100 can be arranged. Forces acting on the window or door frame, however, are not introduced into the roller shutter box 100, since the mounting bracket on the frame 14 and the upper beam acting forces in the lintel 15 initiates without the shutter box 100 is loaded significantly.

The one related to the FIG. 1 described mounting bracket 1 is in FIG. 2 as an integral part in the cross-sectional drawing of a roller shutter box 100 according to the invention in engagement with a lintel 15 and a frame 14, shown ..

In FIG. 2 Accordingly, one recognizes a section through a roller shutter box 100 with the above-described, integrated mounting bracket 1 in the assembled state, ie together with a section through a lintel 15 or a corresponding building ceiling and with a window or door frame 14th

A partially broken perspective view of this embodiment is shown in FIG FIG. 3 reproduced

The roller shutter box 100 consists essentially of four extending in their longitudinal extent perpendicular to the plane of the paper walls, which form a cavity for receiving a winding shaft, not shown here and a roller shutter, also not shown. The roller shutter box has an upper wall 10 with a top 10a, an inner wall 11 with an inner side 11a, and a lower wall 12 with a lower side 12a, the lower side 12 being configured here as a separately attachable closure cover providing access to the inside the roller shutter box recorded parts easier. Parallel to the inner wall 11 extends on the outside of the upper wall 10 of an outer wall 13 with an outer surface 13a. The lower wall 12 closes the lower box opening only partially and in particular leaves a slot for the extension and retraction of a roller shutter free. At the ends of the shutter box, not shown, there is a bearing for receiving a winding shaft, with corresponding Raffstorekästen, which are also subject of the invention, of course, have no winding shaft and corresponding bearings,

The mounting bracket 1, also shown here in section, consists essentially of a vertical leg 2, a lower, horizontal leg with the connecting element 3 and an angled sheet metal attached to the upper end of the vertical connecting web 2, consisting of a horizontally extending flange 4a and an angled End 7 is bent, the end facing away from the flange 4a and is connected to the connecting web 2 and thus the flange 4a is additionally supported.

The in FIG. 2 shown in section mounting bracket corresponds exactly to the in FIG. 1 in a perspective view of the mounting bracket 1 and the in FIG. 5 in section or viewed from the side. Mounting bracket corresponds to the in FIG. 4 in a perspective view illustrated mounting bracket 1 '.

The FIG. 3 shows a corresponding perspective view, wherein the shutter box is shown only schematically and extends in reality in the longitudinal direction to both sides on the mounting bracket 1 addition. The number of mounting brackets along a roller shutter box of course depends on the total length of the roller shutter box, more precisely from the Total length of extending below the shutter box frame or upper spar 14 of the frame.

Conveniently, mounting brackets are generally arranged at maximum distances to the next side wall or from each other from about 1 m to 1.5 m.

The flange 3a, which is attached to the horizontal leg 3, is connected to the upper spar 14 of a window or door frame. For this purpose, the flange may have, for example, mounting holes which are screwed into the spar 14. However, the flange 3a can also have on its underside projections or recesses which engage in complementary recesses or projections on the upper side of the frame.

The lower wall 12 may optionally be made separately, in particular, the mounting bracket 1 and its horizontal leg 3 at the position 20, a separation point, for example, a stable connector having, so that the end portion of the horizontal leg 3 together with the flange 3a in a corresponding mold for the preparation of the lower wall 12 can be inserted so that these parts are optionally made separately and assembled together only during assembly of the roller shutter box and the mounting bracket.

Since in practice the forces occurring (in particular wind loads) are predominantly horizontal forces whose direction of a horizontal line within the plane of the paper FIG. 2 corresponds, it depends essentially on the fact that the mounting bracket 1 just receives such in the figure either to the left or to the right on the frame 14 acting forces and on the horizontal leg 3 and the vertical leg 4 and the flange 4a in the ceiling or the fall 15 abolishes.

It follows that for the effective transmission of such forces and corresponding moments, especially the transition from the vertical leg 2 to the upper connection element 3 and the upper leg 4 should be particularly angularly rigid, and that the connection of the connection element 4 with the lintel 15th or the ceiling should be particularly angle stiff. In this regard, the preferred embodiments are aligned with most of the figures shown.

In the embodiment according to FIGS. 4 and 5 the flange 4 'has a much larger projection and extends in the mounted state further outward along the upper side 10a of the upper wall 10. The basic shape of the mounting bracket 1' in the side view is thus substantially C-shaped, with the longer flange 4 'forms the upper C-leg.

In all embodiments illustrated herein, the outside of the mounting bracket, i. the lower surface of the horizontal leg 3 including the flange 3a, the inside of the vertical connecting web 2 and the top of the flange 4a flush with the contour or the corresponding outer surfaces of the roller shutter box. This can be achieved, for example, by placing one or more fixing brackets distributed over the length of the roller shutter box with the appropriate dimensions into a corresponding shape for foaming and producing the roller shutter box.

In a variant of a mounting bracket according to the invention, not shown here, instead of an upper mounting flange 4a or 4 'or on such a flange, a fastening anchor is provided, which is embedded in the ceiling or a fall above the roller shutter box. This results in a particularly stable connection between the mounting bracket 1 and the lintel 15. In such a variant, a length adjustable horizontal lower leg or a corresponding connection element for attaching the frame may be particularly useful, especially if the exact design of the frame for Time of Einbetonierens the mounting bracket is not yet determined.

The embodiment according to FIG. 6 shows a in the side or sectional view substantially also C-shaped mounting bracket 101, however, wherein the vertical leg 102 and the horizontal legs 103 and 104 are made of profiled sheets and the upper C-leg 104 is made significantly longer than the flange 4a in the first embodiment.

For stiffening the angle between the vertical leg 102 and the upper leg 104, at least one truss node 107a, 107b (in this case two truss nodes) of struts is provided in this embodiment. In this case, the struts consist of simple metal strips, which are connected to each other at a central point and extend from there in a star shape in three directions such that the free end of one of the three lattice nodes forming plates exactly with the corner transition between the vertical leg 102nd and the horizontal leg 104 is connected and the free ends of the other two sheets are connected at a distance to this corner with the vertical leg 102 and the horizontal leg 104.

This results in minimal material use an extremely stiff angle connection between the vertical leg 102 and the horizontal leg 104. The individual connections between the sheets 107a, 107b, the connecting web or leg 102 and the flange 104 can in particular be produced by welding. Of course, instead of the sheets, it is also possible to use round bars or bars with other cross-sectional shapes for producing the truss nodes.

At the same time, the embodiments of the FIGS. 4 to 7 at their upper legs 4 'and 104 mounting options on the lintel 15 or a ceiling at a relatively large distance, measured along the longitudinal extension of the leg or flange 4' and 104, which effectively a particularly angle-rigid mounting of the vertical leg 2 and 102 causes, so that its lower end in the horizontal direction (from inside to outside and vice versa) can hardly be deflected. This ensures the transmission of corresponding forces and moments from the frame 14 to the lintel 15.

In the present embodiment, right and left adjacent to a central profile bead of the sheet metal profiles, from which the vertical leg 102 and the horizontal leg 104 are made, two corresponding truss nodes with the corresponding portions of the legs 102, 104 are connected.

FIG. 7 shows again the embodiment according to FIG. 6 together with the lower lower leg 103, separate from the vertical leg before assembly, which in this case is made together with the lower wall 112 of the roller shutter box. With the closing of the underside of the roller shutter box through the closure lid 112 (of course leaving the outlet slot for the roller shutter free), the two legs 102 and 103 are preferably interconnected in the region of their end portions, wherein the compound a simple tongue and groove connection, a screw or may also be another positive connection and / or adhesive connection.

Angular rigidity is virtually non-existent at this lower connection point because any horizontal loads acting on the window or door and upper spar 14 by wind pressure or wind pressure caused by wind flow exclusively in the longitudinal direction of the lower leg 103 be transferred to the connecting bracket, wherein the vertical leg 102 initiates this force due to the angularly rigid connection with the upper leg 104 without significant horizontal movement of the lower end of the connecting web 102 in the ceiling or the lintel 15.

It is essential only the positive and preferably positive connection between the horizontal leg 103 and the lower end of the vertical leg 102 in the horizontal direction, but this also by no means precludes a rigid connection in this area. Vertical relative movements between the frame 14 and the ceiling or the lintel 15 occur in practice (apart from earthquakes) only to a much lesser extent and can also be easily compensated by appropriate slight deformation of the roller shutter box and / or the mounting bracket, without any forces to be transmitted, as appropriate power transmissions in the vertical direction between the walls and a fall or a ceiling are transmitted sufficiently secure. Alternatively, of course, both corner transitions between the vertical leg and the two horizontal legs can also be made angularly rigid in order to transmit horizontal and vertical forces.

In the FIG. 8 is shown a further variant in which the upper flange 4 'of a mounting bracket, for example according to FIG. 4 can be inserted into a rail 25 with lateral undercuts and fixed, for example, with the help of one or more locking screws. The profile of the rail can be described as a flat rectangular profile with U-shaped bent side edges, the open U-sides are directed towards each other. This U-shape is dimensioned so that the side edges of the flange (preferably with a small clearance) can be accommodated therein, the flange being wider than the clear distance between the opposing U-profile shapes, but also narrower than the clear distance between the ground the grooves formed by the U-profile shape. The rail 25 may in turn be secured by screws or by gluing on the lintel 15 or the ceiling or be embedded in concrete according to a variant in the lintel 15 or the ceiling and sufficiently protruding from this, so that the flange 4 'inserted from one end of the rail can be. FIG. 9 shows a variant in which the role of rail and flange over the embodiment according to FIG. 8 is reversed, ie the flange 25 'is fixed to a ceiling or a lintel 15 (eg embedded in concrete with an integrally formed anchor), while the connecting element 4 is designed as a profile rail matching the flange 25'.

FIG. 10 again shows a between a frame 14 and a lintel 15 mounted roller shutter box 100, in which for the attachment and fixing of the mounting bracket 101 FIG. 6 has been used. In this case, however, the upper flange 104 of the mounting bracket 101 is glued to the lintel 15 via an adhesive layer 30. Also, the top of the roller shutter box 100 may be glued to the lintel 15 or the gap between the top of the roller shutter box 100 and the bottom of the lintel 15 is filled with another material, for example a mounting foam 31, compared to the adhesive layer 30th does not necessarily have to have the same adhesive properties.

The rest in the FIGS. 11 to 16 Variants shown all show mounting brackets that are bonded directly or indirectly to the lintel 15. In the embodiment according to FIG. 11 was doing a mounting bracket according to the FIG. 8 used, with a rail 25 is glued with a flat top with the lintel 15. In all glued variants, the adhesive surface in the plan view or in the profile impression on the lintel 15 should be 80 cm ² or more if possible.

In FIG. 12 the upper flange 4b is further modified relative to the flange 4a in that it has a larger area and lateral webs 24 which has a space 26 for receiving a particularly well-adhering adhesive, for example in the form of a foam.

Figure 12-1 shows a corresponding detail of the mounting bracket 1 with the modified flange 4b and the webs 24th

In FIG. 13 a further variant of the mounting bracket 1 is shown with a modified mounting flange 4c, the L-shaped angled webs 27 has on its upper side, the undercut receiving spaces 26 'form an adhesive, as shown in the detail view Figure 13-1 recognize more accurately.

Another variant of a mounting bracket 101 a, analogous to the mounting bracket 101 in FIG. 6 is trained in is FIG. 14 shown.

In this case, the modified flange 104a has additional vertical webs 124 which in turn define receiving spaces 26 for an adhesive foam, again in the detail view of FIG Figure 14-1 is clearly visible.

Another variant 101 b of a mounting bracket similar to that in FIG. 6 shown mounting bracket 101 is in FIG. 15 recognizable, wherein the mounting flange 104b in this case with the mounting flange 104 from FIG. 6 is substantially identical, but which is provided with additional compression bands or sealing strips 105, which also define a receiving space 26 for adhesive. Again, this is in a detail view according to Figure 15-1 shown in more detail. Another variant 101c of a mounting bracket analog FIG. 6 is in FIG. 16 shown, in which case the flange 104c dovetail-shaped receiving spaces 26 which serve to receive an adhesive and even better anchoring of the flange 104c with a lintel 15 should effect. Again, here is an adhesive layer 30, wherein the gap between the top of the roller shutter box 100 and the bottom of the lintel 15 may be filled with the same adhesive 30 or a simpler and less well-adhering mounting foam.

Of course, this also applies to the other embodiments, which in the FIGS. 10 to 15 are shown.
