EP3511511B1 - Assembly kit for a building opening shading device - Google Patents

Description

The invention relates to a kit for a vertical awning or a roller shutter according to the preamble of claim 1.

Building opening shading devices, such as vertical awnings or roller shutters, generally have a winding shaft and a curtain that can be wound up and unwound thereon, as well as a box housing the winding shaft with a passage slot on the underside for the curtain. In the case of top systems, the curtain is placed on a door or window frame, in contrast to stem systems. The box has a jacket which extends coaxially, that is to say along the winding shaft around the winding shaft, and which connects two end covers or end caps to one another.

Deviating from this, the French patent application shows FR 2927933 A1 a basic system reduced to the essentials, in which the two front side parts are only connected to one another by rails.

Such basic systems are used in building renovation to replace built-in shutters in existing installation spaces. The compact design creates the space required for thermal insulation in the installation space.

The European patent application EP 1 213 435 A2 shows a roller shutter kit, in which a basic system with a closed box made of flat metal profiles is installed in an insulating shell, which is dimensioned to fill in a lintel-side installation space in the old building above the window opening.

Such roller shutter solutions that are specifically adapted to a given installation space and therefore have to be manufactured separately for each individual case are unsuitable for the new building area. Here, for cost reasons, it is important to have a high degree of uniformity in differently dimensionable systems with the greatest possible manufacturing tolerances.

It is therefore an object of the invention to develop a kit for a building opening shading device of the generic type in such a way that, with a high degree of uniformity in production, relatively large manufacturing tolerances are possible with as many components of the kit as possible, and the overall result is a lightweight construction.

This object is achieved with the features of claim 1.

According to the invention, a basic system reduced to its essential functional elements is provided. This basic system has the winding shaft and the associated curtain, as well as a carrier for the winding shaft. The winding shaft carrier thus has two end bearing plates for the winding shaft and a number of bridge elements which firmly connect the two bearing plates to one another and thus span the winding shaft.

This basic system thus has all the functional elements necessary for the function of the building opening shading device - providing a curtain that can be opened and lowered in front of the window or the door to be shadowed - which must be manufactured with a correspondingly tight tolerance and placed precisely aligned to the building. However, the basic system also has no more than what is necessary to provide the basic function of the building opening shading device - the opening and lowering of the curtain Components.

Rather, the kit according to the invention comprises an additional housing, which forms the jacket which extends coaxially around the winding shaft or at least a part thereof. The additional housing can thus take over all supplementary functions of the building opening shading device, such as filling the on-site installation opening for the building opening shading device as heat-tight as possible, and, in the case of a basic system attached to the additional housing, complements the winding shaft support to the box housing the winding shaft. The base system can be moved along the winding shaft axis with the base system attached to the additional housing relative to the additional housing. In addition, the same profiles that form the additional housing can be used for different basic systems, as long as the interfaces at which the additional housing and the basic system are to be joined are the same.

The additional housing can thus be manufactured with relatively high manufacturing tolerances from relatively inexpensive materials (plastic), whereas the basic system that is to be made to measure only has the components that are absolutely necessary for the main function of the building opening shading device and is displaceable compared to the additional housing and the window to be shaded due to the displaceability can be easily and precisely positioned on the additional housing.

Advantageous further developments are the subject of the dependent claims.

For example, a section of the casing seated on the door or window frame is advantageously formed on the additional housing, so that the basic system can be freely positioned relative to the door or window frame by moving it along the additional housing.

Furthermore, the kit which is the subject of the application advantageously has guide rails for the curtain which can be wound up and unwound on the winding shaft and which guide the curtain in front of the window when opening and lowering of the door on its sides and / or, in the case of a building opening shading device designed as a vertical awning, the lower drop rod hanging on the curtain. These guide rails can have insert tabs or pins projecting from the top, which can be inserted into corresponding insertion openings on the base system in order to connect the guide rails to the base system. The guide rails can thus be freely positioned together with the basic system in relation to the additional housing, but also in relation to the window or door frame by moving the basic system along the additional housing. The guide rails can therefore be aligned with the base system in relation to the window. The insertion openings for the two insertion tabs or pins are advantageously located on the underside of the two end bearing plates of the winding shaft support.

Furthermore, a number of sliding surfaces running in the winding shaft axis direction can advantageously be provided on the winding shaft support. The number of sliding surfaces can in turn be assigned a - identical or different - number of counter sliding surfaces provided on the additional housing and running in the direction of the winding shaft axis. The arrangement of the sliding surfaces to the counter sliding surfaces is advantageous such that the base system can be moved along the number of sliding surfaces in the axial direction of the winding shaft with respect to the additional housing when the base system is attached to the additional housing. This makes it easier for the fitter on the construction site to align the basic system with the additional housing and the window, since the displacement along the additional housing can take place in a movement that is purely in the direction of the winding shaft axis.

The number of sliding surfaces can either be provided on the number of bridge elements or only on the narrow sides of the two bearing plates. In the former case, the mating sliding surfaces, preferably designed as mating sliding edges, could then be formed on a section of the additional housing on the abutting edges to the base system, forming a box side wall of the casing extending around the winding shaft. In the second case, it would be against it it is conceivable to accommodate the basic system in an additional housing that completely or almost completely encloses the basic system on the casing side, and that is displaceable via its side parts matched to the internal cross-sectional shape of the additional housing.

In this case, at least one of the number of counter sliding surfaces can be formed on a guide groove, against which a sliding surface formed on a guide projection engaging in the guide groove bears when the basic system is attached to the additional housing. This ensures that when the basic system is moved along the additional housing in the direction of the winding shaft axis, there is no undesired displacement in the transverse direction. Of course, the sliding surface can also be formed in a guide groove and the associated mating sliding surface on a corresponding guide projection engaging in the guide groove.

In terms of good thermal and / or acoustic separation, it is advantageous if the winding shaft support of the basic system consists of a different material than the additional housing. Due to the desired separation of functions, the additional housing can also be made from a material that is much cheaper than the basic system to be manufactured with relatively narrow tolerances or its winding shaft support. The additional housing can thus be made of plastic, for example, while the winding shaft support can be made of metal. The plastic of the additional housing can be present, for example, in the form of plastic profiles which form side walls of the box housing the winding shaft. However, it would also be conceivable to manufacture at least part of the additional housing from foamed plastic, for example in the form of voluminous styrofoam elements, which can then also perform the function of thermal and acoustic insulation in addition to the housing and along with the sliding surfaces or edges Have metal strips or the like fogged up.

Two end faces that can be placed on the additional housing are also advantageous Cover caps provided. After aligning the basic system on the additional housing, a final position fixation of the basic system in the desired end position can then be produced using these caps. The two blind caps which can be placed on the end face of the additional housing thus limit the displaceability of the base system relative to the additional housing when the base system is attached to the additional housing.

The two blind caps can be provided with a layer of heat and / or sound insulation material, in particular if the kit is intended for a building opening shading device which has corresponding sound or heat insulation properties. In this case, additional insulation elements can be inserted in the additional housing, which extend along the winding shaft, on the inside of the building of the box formed by the additional housing and the basic system, so as to insulate the interior of the building against the exterior of the building heat and / or sound.

In this sense, it is also advantageous if the base system on the passage slot for the curtain is provided with sound sealing strips, which can be arranged on the inside and / or outside of the passage slot, in conjunction with a kit designed as a vertical awning kit in such a way that it fits when the curtain is fully wound, place it on the drop rod and thereby provide additional sound insulation. The material of the sound seal can be rubber, soft plastic or the like.

According to a first variant, the number of bridge elements of the winding shaft support spanning the winding shaft forms a section of the casing which extends coaxially around the winding shaft, whereas the additional housing forms a further section of the casing and is blunt or overlapping with the number of counter sliding surfaces on the number of sliding surfaces on the Has box side wall elements adjacent bridge elements. The number of bridge elements of the winding shaft support can, for example, be one in the installed state of the building opening shading device Form the exterior of the box facing the outside wall and adjacent sections of a box top and bottom wall. The same or different number of box side wall elements or bridge elements of the winding shaft carrier can then have a box inner wall and adjacent sections of the box top and box bottom wall forming box side wall elements, so that the basic system, when attached to the additional housing, complements the additional housing with its winding shaft carrier to the box housing the winding shaft.

The insulation elements already mentioned above, which extend along the winding shaft, can then be inserted into the additional housing and extend over the entire height and length of the box inner wall, i.e. fill the space between the box top and box bottom walls, in order to effectively insulate the interior of the building from the outside of the building to reach. If the insulation elements are provided for thermal insulation, they can consist, for example, of plastic foam such as PU foam, of bakelite or the like. In contrast, heavy foils made of rubber or the like are particularly suitable for sound insulation.

In a further advantageous variant, the basic system is designed as an insert which is enclosed by the additional housing at the top, inside the building and outside of the building, when the basic system is attached to the additional housing and can have an inspection cover on the underside. In contrast to the variant mentioned above, the revision is then carried out from below and not from the inside of the building. The additional housing can thus be designed as an outer housing which can be inserted and in particular can be plastered into an installation space above the door or window frame, which for this purpose can have a plaster edge profile which extends along a lower edge of its section forming the outer box wall and which clears the plaster layer on the underside when plastering the outer box wall limited. In this variant, too, the heat and / or sound insulation of the interior of the building relative to the exterior of the building can take place in the area of the box inner wall. This can be a The inner wall-forming section of the additional housing may be thicker than a section of the additional housing forming the outer wall of the box and consist of a heat and / or sound-absorbing material, namely, for example, PU foam, bakelite etc. It would also be conceivable, however, for the section of the additional housing forming the inner wall of the box to be provided with a cavity and to fill this cavity with a heat and / or sound-insulating material, for example mineral wool, etc.

It is further preferred if the kit has a receptacle for an adapter for connection to the door or window frame in the section of the casing of the box surrounding the winding shaft that is seated on the door or window frame. Because the window manufacturers often manufacture their windows with appropriate connectors, which, however, are not standardized and vary depending on the window and window manufacturer, so that compatibility with different windows or window manufacturers can be established using different adapters that can be inserted into the corresponding receptacle ,

It would also be conceivable to accommodate several basic systems in a row next to one another in a single additional housing. This could shade several windows at once if, for example, there are several windows next to each other on the building. If the basic systems are to be arranged at a distance from one another, the area between two basic systems can be determined at the desired position after the positioning of the basic systems with respect to the additional housing by displacement through an on-site cover and / or with plasterable insulation in the intermediate space.

First, reference is made to the Figures 1 and 2 1, which show a basic system 1a, which comprises a winding shaft support 2, 3, 4, 6 connected to guide rails 9 and the winding shaft accommodated thereon with the curtain 7 wound on the winding shaft and the drop bar 8 hanging on the underside of the curtain 7. The winding shaft support 2, 3, 4, 6 comprises two end bearing plates 2 for the winding shaft, as well as a box outer wall 3 pointing towards the outside of the building in the installed state and a segment 4 of a box top wall. The box outer wall 3 and the box top wall segment 4 serve as the two bearing plates firmly connecting the bridge shaft spanning bridge elements 3, 4 and, like the side parts 2, can be made of metal, for example as extruded profiles.

How Figure 3 shows, the two end bearing plates 2 each have an underside insertion opening 11, into which an insertion tab 10 projecting on the upper side of the associated guide rail 9 can be inserted in order to connect the guide rail 9 to the associated bearing plate 2 and thus ultimately to the base system 1a. Again Figure 3 can also be seen, the winding shaft support 2, 3, 4, 6 also comprises a bridge element 6 designed as a bottom wall segment, which connects the two end bearing plates 2 to one another on the bottom side.

The Figure 4 shows the basic system 1a now in a state placed on a window frame 12. It should be noted, however, that the bottom box wall segment 6 of the base system 1a does not sit directly on the window frame 12, but rather on an adapter profile 5 which provides a receptacle 13 for an adapter for connection to the window frame 12, but which is not part of the base system 1a, but rather Part of an additional housing 1b, as in particular from the Figures 6 and 7 evident.

A built-in state like the one Figure 4 shows is not considered in reality. Rather, the additional housing 1b was in contrast to Figure 6 only largely omitted in the drawing in order to better emphasize the seating of the base system 1a with its base-side bridge element 6 on the profile 5 of the additional housing 1b forming the receptacle 13 for the window frame adapter.

As especially in the Figure 5 is clearly visible, the base wall bridging element 6 of the base system 1a has sliding surfaces 15, 16 formed on projecting webs, which, see Figure 4 , in the state of the base system 1a attached to the additional housing 1b, bear on corresponding mating sliding surfaces on the profile 5 of the additional housing. At the same time, the cover wall segment bridging element 4 has a sliding surface 14 formed on a projecting hook channel, which, like that Figures 6 and 7 show, abuts against a sliding surface 24 formed in a guide groove on a cover wall segment 19 of the additional housing 1b.

The base system 1a can thus be displaced in a guided movement relative to the additional housing 1b, specifically with sliding surfaces 14, 15, 16 abutting the mating sliding surfaces of the additional housing 1b. The position of the base system 1a and thus the guide rails 9 attached to the window frame 12 can thus be in the attached to the additional housing 1b in a simple manner, namely by moving along the additional housing. The bridge elements 3, 4, 6 of the basic system 1a form and the side wall systems 5, 19, 20, 21 of the additional housing 1b have a jacket 3, 4, 5, 6, 19, 20, 21 coaxially surrounding the winding shaft.

Once the desired end position has been reached, the base system can be fixed in this end position by two cover caps 22, which can be attached to the end of the additional housing 1b, like that Figures 8 and 9 demonstrate. The blind cap 22 can then be connected, for example via an angle plate 23, to the base system 1a located in its desired end position and thus fix the base system 1a in this desired position.

From a comparison of the Figures 8 and 9 one recognizes that the basic system 1a according to Figure 8 compared to the additional housing 1b in the longitudinal direction of the winding shaft, whereas it is in accordance with Figure 9 almost flush with the additional housing. The indentation according to Figure 8 who also in Figure 7 is clearly visible, it serves to be able to introduce a layer of insulating material between the cover cap 22 and the front bearing plate 2 of the base system 1a in order to include the box formed by the winding shaft supports 2, 3, 4, 6 of the base system 1a and the additional housing 1b to provide thermal insulation on the front. This is because the box is filled on the side of the additional housing 1b, i.e. in the area of the box interior wall facing the inside of the building, with thermal insulation elements 17, 18 in order to bring about a thermal separation of the building interior from that of the box interior which is connected to the outside of the building via the passage slot for the curtain 7 , Furthermore, on both sides of the passage slot for the curtain 7 in an area into which the drop rod 8 runs when the curtain 7 is completely wound onto the winding shaft, on both sides of the drop rod 8 sound sealing strips 25 are attached, which come into contact with the drop rod 8 on the latter and thus reduce the passage of airborne sound from the outside in. The sound sealing strips 25 can consist of rubber or soft plastic or the like.

The Figures 10 to 12 show a further embodiment of the Vertical awning kit according to the invention, which is suitable for plastering in an existing installation space. The additional housing 101b here encloses the base housing 101a with its sections 119, 103, 107 forming the box top wall, the box outer wall and the box inner wall, and to a certain extent also on the bottom side. Different from that in the Figures 1 to 9 shown vertical awning kit, in which the revision can be done from the inside of the building via a removable box inner wall profile 20 of the additional housing 1b is in the in the Figures 10 to 12 shown embodiment provided a revision from below on the outside of the building. For this purpose, the base system 101a has an inspection cover 106 on the underside.

The two end winding shaft bearing plates 102 are in turn connected to the winding shaft support 102, 104, 106 of the basic system 101a by a number of bridge elements 104, 106 which firmly connect the two bearing plates 102 and span the winding shaft, the bridge element 104 receiving the main load bearing being sickle-shaped extends downward from the top of the box in the area of the interior of the additional housing 101b on the inside of the box to the guide rail 109. A sliding surface 114 serves as a circumferential surface on the outer contour of the two end bearing plates 102, on which the bearing plates 102 and thus the base system 101a abuts against a counter sliding surface 124 of the additional housing 101b. The counter sliding surface 124 is thus located on the inner contour which extends along the additional housing 101b. Here too, the basic system 101a can be moved in a guided movement relative to the additional housing 101b in the longitudinal direction of the winding shaft.

The vertical awning is in turn attached to the window frame 112 via the additional housing 101b, so that the base system 101a can also be freely positioned relative to the window frame 112.

The additional housing 101b has a relatively thin box top wall plate 119 on the upper side, and also a plate 103, which is also kept relatively thin and forms the outer wall of the box, on the underside of which a plaster edge profile 125 is attached. A substantial part of the thick-walled profile 117 of the additional housing 101b, which surrounds the winding shaft 103, 106, 117, 119, consists of a dimensionally stable insulating material, such as polystyrene with plastic lamination, and forms the inside wall of the box and clad the box top wall from the inside. The profile 117 thus also acts as a thermal insulation element.

To connect the additional housing 101b to the window frame 112, a receptacle 113 is in turn provided for a two-part adapter 126, 127 for connection to the window frame 112 on the underside of the profile 117. The adapter 126, 127 has an adapter lower part screwed onto the window frame 112 and an adapter upper part 127 attached to the profile 117, so that the vertical awning can be pushed onto the window frame 112 when the basic system 101a is inserted into the additional housing 101b.

In contrast, the assembly of the in the Figures 1 to 9 shown vertical awning kit on the window frame 12. Here, the additional profile 1b can first be attached to the window frame 112, whereupon the basic system 1a can be attached to the additional housing 1b and can then be freely positioned along the winding shaft. But also in the Figures 10-12 As shown in the vertical awning kit, the basic system 101a can still be moved in the additional housing 101b after the vertical awning kit has been placed on the window frame 112 and thus positioned relative to the window frame.
