EP3043018B1 - Building opening shading device with a lateral guide rail - Google Patents

Description

The invention relates to a building opening shading device with a curtain which can be pulled up and down in front of a building opening and which is guided to its two sides in each case in a guide groove of a side guide rail.

On the awning fabric of known vertical awnings are usually attached to both side edges as half-zippers executed edge members. With these kederartig recorded in the side guides of the vertical awning edge members, the awning fabric is kept tension. In each case an insert is guided in the two lateral guide rails, which has a Kedernut, in which the edge members of the awning fabric are threaded when draining the awning fabric. The inserts in the guide rails are based on elastic damping elements on undercuts of the guide grooves of the guide rails, so that the drained awning curtain is held in tension in the transverse direction, but there is a certain flexibility, which is determined by the or the elastic damping elements. This compliance is necessary to prevent the awning fabric from breaking during wind gusts and to compensate for manufacturing tolerances and wear-related fabric shrinkage resulting from the nature of the mostly textile material of the awning fabric. The awning fabric is attached with its upper end to a winding shaft and with its lower end to a mostly weight-weighted end or Fallstabprofil, which is also performed in the side guide rails. A generic vertical awning is the DE 10 2009 007 682 A1 refer to.

Also the international patent application WO 2013/167786 A1 shows such a vertical awning. In the embodiment of Figure 6, the profile is semi-zippered with a series of staple elements provided side edge of the curtain surrounds, in turn rotatably mounted in the side guide rail.

Other known vertical awnings are guided only on their Fallstabprofil, but not held on the side edges of the awning fabric, so that these vertical awnings tend to flutter or even rupture of the cloth in gusts when they are mounted unprotected on the outside of the building. An example of this is the European patent application EP 2 031 176 A2 which shows a vertical awning in which the fall bar profile is guided laterally on a vertically tensioned rope.

Venetian blinds were also equipped in the past with wires or ropes stretched on both sides of the blind on which the lower end bar or the lower hanging bar was threaded and thus guided, see, for example, the German Utility Model DE 7002243 U , Due to the susceptibility to wind, however, this has not prevailed. Today, external venetian blinds are therefore usually delivered with building-proof side guide rails, in which the lower hanging strip and the blinds are guided.

While with high-mounted lateral guide rails, a high wind stability of drained curtain is achieved so that no similar filigree and reduced to the minimum optics of the lateral guides can be achieved as with such wires, which would be desirable from an architectural point of view but in many cases.

Even more stable, but also visually conspicuous are frame constructions in which the side guide rails are joined together at the top and bottom with cross-tie beams to form a frame that can be attached to the building as a whole. The US patent application US2004 / 0144498A1 shows a storm screen with such a frame construction.

The object of the invention is therefore to provide a building opening shading device with good wind stability of the blind and appealing look.

This object is solved by the features of claim 1.

The building opening shading device according to the invention has a lateral guide rail on both sides of the curtain. According to a first aspect of the invention, at least one of the two side guide rails is penetrated by at least one longitudinally extending parallel to the guide channel, is passed through the at least one elongated attachment member which is above the building and attached below the side guide rail. In this case, a holder is provided for building-side fastening above and below the respective side guide rail, to which the respective fastening member is mounted stretched to train.

This allows a very slim and reduced to the minimum optics of the side guide rails can be achieved, which is particularly advantageous for applications such as glass facades, in which the side guide rails can not be housed in a wall reveal, but survive on the facade. Furthermore, in such and other cases, the structural conditions often do not allow attachment of the guide rails on the window frame or in the window reveal, e.g. on the mentioned glass facades. Especially for such cases, it is advantageous that the side guide rails of the building opening shading device according to the invention can be stored at only two points, one above and one below the respective side guide rail on the building or the facade or on associated components.

According to an alternative or additional aspect of the invention, at least one of the two side guide rails at the top and bottom each have at least one insertion opening extending parallel to the guide groove in the longitudinal direction into the side guide rail, wherein in the upper and the lower insertion opening in each case at least one elongated attachment member is inserted, which is above the building or mounted below the side guide rail. In this case, a holder is provided for building-side fastening above and below the respective side guide rail, to which the respective fastening member is mounted stretched to train.

For example, a round bar above and below the side guide rail could be inserted into a slot of a bracket acting as a bracket or the like and have at its upper and lower ends a thread on which a nut is screwed to bias it against the slotted wall of the holder , However, it would also be conceivable to form the respective attachment member integrally with the holder, for example in the manner of a door hinge with a holder which is provided with an inserted into the associated insertion opening of the side guide rail hinge pin section.

Advantageously, the upper-side holder is attached to a side part of a winding shaft box or formed integrally therewith, ie a side part of a box in which a winding shaft is rotatably mounted on the curtain for winding and draining up and is taken unwound. Since on the one hand the side guide rails can no longer serve as fixed side guide rails for supporting the winding shaft box and on the other hand, the tensile forces of attached to the top holder mounting member must be added to the top holder is advantageously designed as a box attachment fastener, in addition to the associated attachment member also still the box fixed on the building side, eg hung up. By contrast, the lower-side holder can be designed as a spacer fastened to the facade. In order to adjust the distance of the side guide rail of the façade front in particular as a spacer with a austeleskopbaren from the facade away boom to which the fastening member is attached.

The invention is particularly suitable for a building opening shading device designed as a vertical awning. Accordingly, the building opening shading device advantageously has a drapery designed as a cloth web with its welt edges extending along Kederabschnitten, wherein the curtain is guided by means of the opposite the curtain cloth thicker Kederabschnitte in the undercut guide grooves of the two side guide rails and held on train. This results in a higher wind stability and a better cloth appearance than in a curtain, which is guided laterally only on a lower side drop bar, but is not held even to tension, as in the above-mentioned cases, where there is a slim design of the side guide rails arrives, has been used so far.

In order to further narrow the width of the side guide rails in the normal direction to the facade and still allow safe guidance of such a lower Endstabs or case bar, which is usually complained with weights to keep the curtain down taut, is at the bottom of the curtain advantageously attached to an end bar, the two guide rails facing sides in each case two fork-shaped projecting towards the respective guide rail and in the normal direction to the Behangbene at least the width of the guide rail spaced flank webs, which engage on at least one side of the blind the local guide rail. The flank webs then guide the end bar on the outer surface facing the facade and facing away from the facade.

It would be conceivable to attach rollers to the edge webs in order to be able to use these outer surfaces of the respective side guide rail without the associated wear as running surfaces. Furthermore, the end bar on at least one side of the curtain can have a the two fork-shaped protruding flank webs on the back of the guide rail facing away from the curtain interconnecting connecting web to secure the end bar on the guide rail even better.

In the applications described above, such as glass facades are in contrast to previously used vertical awnings with only the case bar led blind completely closed for review combined systems (series connection of several systems) feasible if at least one of the guide rails on the opposite side of the guide channel, through the the elongate attachment member is guided, an additional guide groove for a curtain of another, laterally arranged next to the building opening shading device, another building opening shading device.

It has proved to be particularly advantageous if the longitudinally extending fastening member of one or both lateral guide rails is designed as a cable, in particular as a steel cable which extends through the channel of the lateral guide rail provided for this purpose. However, it would also be conceivable for a wire extending through the channel or a shaft or rod extending through the channel, preferably a steel or something similar, to be used.

However, it is not mandatory that the fastening members of the side guide rails are continuous. For example, it would be conceivable to provide one or both side guide rails with two pins serving as fastening members, which are inserted at the top and bottom into end-side insertion openings of the channel. It would also be conceivable, above and below mount a (steel) rope or a thickened shaft provided with a nipple on a corresponding undercut of the channel, in particular in a two- or multi-part design of the lateral guide rail, which introduces the nipple or another Would allow final thickening in the channel. Likewise, it would be conceivable, above and below a serving as a fastening member rope around a the insertion opening of the channel crossing the anchoring web and the free end of the rope outside the insertion with the rope to crimp or the like. For such, non-continuous fastening members, the respective guide rail would not have a continuous channel for it. Corresponding insertion openings at the top and bottom would be sufficient, although the guide rail is advantageous for cost reasons formed as a profile component or interconnected profile components.

For cost and weight reasons, it is preferred if at least one, preferably both side guide rail made of plastic, in particular consists of one or more plastic profiles. Since non-continuous fastening members require a significantly higher intrinsic stability of the guide rail than a continuous fastening member such as a steel cable, continuous fastening members are better for this, without having to forego the desired slim design of the side guide rail. However, it would also be conceivable to manufacture the guide rail from a relatively expensive and heavy material such as steel or aluminum, for which then non-continuous fastening members would be well suited.

A multi-part construction of the lateral guide rail can facilitate assembly, in particular in the case of a continuous fastening member, for example in the case of a guide rail consisting of two profiles with a separation plane running through the channel, which permits insertion of the fastening member prior to assembly of the lateral guide rail. The two profiles of the side guide rail can be designed to latch together with each other, so for example along their longitudinal sides corresponding latching projection sections / latching hook sections have. Furthermore, it would be conceivable, in particular in the case of an existing plastic side guide rail to connect the two halves of the side guide rail on one longitudinal side over a number of hinges, such as a film hinge, and on the other longitudinal side to provide the necessary latching latching sections. After inserting the attachment member can The two guide rail halves then simply folded and locked together, so that there is a simple assembly vpn side guide rail and mounting member.

Especially in building opening shading devices such as vertical awnings, which have to be held on tension in the side guide rails curtain, but due to occurring over time cloth shrinkage and caused by temperature fluctuations expansion variations on curtain and side guide rail a certain yielding of the side guide rails in response to the pulling force exerted by the curtain need, it is advantageous if one or both side guide rails is resiliently attached to the building or are. Advantageously, one or both side guide rails are mounted resiliently on the associated holders via a fastening member or fastening members. For this purpose, the respective attachment member above and / or below the at least one side guide rail via a damper, rubber or spring element such. a spring cup to the holder to be held tensioned.

In the case of a continuous rope used as a fastening member or of two ropes suspended at the top or bottom of the lateral guide rail, the cable may advantageously have a certain flexibility or elasticity in order to allow the side guide rail (s) to move to the desired extent, So to an extent, which ensures that the curtain remains stretched on train. Additionally or alternatively, the rope above and / or below the side guide rail to be connected to a damper, rubber or spring element. The damper, rubber or spring element is then preferably received in a pot attached to the holder.

In the FIG. 1 is a vertical awning according to the prior art DE 10 2009 007 682 A1 shown. Such vertical awnings are usually arranged on the outside of a window inserted in a building opening, etc. The the FIG. 1 underlying vertical awning includes a generally arranged in the region of the upper edge of the building opening box 11, projecting from the side guide rails 12 down. Within the box 11 is a rotatably mounted, driven in the direction of rotation winding shaft 13, on which a web-shaped, consisting of an awning curtain 14 wound or from which this curtain 14 is unwound. The curtain 14 is accordingly attached with its upper end to the winding shaft 13. At the lower end of the curtain 14, a drop rod 15 is attached, which may be provided with weight weights and is guided with its side ends in the guide rails 12.

The curtain 14 passes through a provided in the region of the lower, rear corner of the box 11, over the box length continuous, slit-shaped outlet opening. The box 11 contains lateral, advantageously prepared as moldings side parts 18, which with downwardly projecting spigot for Connection of the guide rails 12 may be provided. The winding shaft 13 is mounted on the side parts 18. The interior of the box 11 is bounded by a circumferential jacket 19, the ends of which are fastened to the side panels or cover caps 18. The jacket 19 comprises a rear wall 20, as well as an upper part 21 and a lower part 22nd

In the guide rails 12, on the one hand, the lateral ends of the drop rod 15 are guided in a guide groove extending in the drawer extension direction. On the other hand, the lateral guidance and tightening of the blind 14 serving guide rail inserts are inserted into the guide groove, which are supported transversely to Behangauszugsrichtung by elastic damping elements on the inner shoulders of the undercut guide groove in the respective guide rail 12. These guide rail inserts each contain a vertically extending groove, which serve as Kedernut for Randkederabschnitte at the side edges of the curtain cloth 14.

The guide rails 12 are seen in the normal direction to the Behangbene very wide, which makes them unsuitable for mounting outside the wall reveal optical reasons. In addition, the guide rail inserts supported by the elastic damping elements are required. This wants to fix the invention.

In the other FIGS. 2 to 5 shown embodiment of the invention, this disadvantage is eliminated without the basic structure of in FIG. 1 vertical awning for it was changed. The in the FIGS. 4 and 5 However, shown in detail side guide rails 2 are significantly slimmer than those in the prior art according to FIG. 1 Deviating from the side guide rails 2 are here above and below the respective side guide rail 2 attached to the building side.

This succeeds, as in the FIGS. 2 and 3 is shown, each by means of a steel cable 1, which is guided by a longitudinally extending along the respective side guide rail 2 channel 6 and thus forms a longitudinally extending attachment member 1, and which is mounted above and below the respective side guide rail 2 in a known professional manner on a building side mounted holder. The holder above the respective side guide rail 2 may be formed at the same time as a carrier or additional box attachment for the box of the vertical awning, which - unlike the in FIG. 1 shown box 11 - no longer supported on the side guide rails 2, but on the two upper-side holders, except for appropriate adjustments (no downwardly projecting pin to connect the guide rails 12, but hook strips for hanging on the top holders or other connection means) but otherwise the in the FIG. 1 shown box 11 may correspond. The lower-side holder can be designed in the manner of a wall-mounted spacer with a telescopic or rigid arm, the steel cable 1 is mounted clamped on the boom to train, either directly or via an intermediate spring element.

The two side guide rails 2 each consist of a one-piece plastic profile, which in addition to the channel 6 for the associated cable 1 has a parallel thereto guide groove 5, which is open to an acting as hanging awning fabric 3 and provided with undercuts 7, see FIG. 5 , On the awning fabric 3 are on both sides as piping acting edge thickenings 4 attached in the form of semi-zipper-like arranged staples, which are advantageously welded to a textile carrier tape 8, which in turn may be welded to the awning fabric 3. The edge thickening 4 of the awning fabric 3 are retained on the undercuts 7 serving as Kedernut guide groove 5, so that the curtain is held in total tension. Not shown is the as in the prior art known at the lower end of the awning fabric 3 mounted, weight-weighted drop rod, which at its two side ends the local Guide rails 2 may each have fork-like encompassing flank webs and so in contrast to the prior art, can not be performed in the guide rails.

The textile carrier tape 8 may have a certain elasticity, as for example from the European patent EP 2 335 956 B1 is known to compensate for changes in length in the awning fabric 3. This can also be a resilient attachment of the steel cord 1 serve on the top and / or bottom bracket, such as by means of the aforementioned suspension of the steel cord 1 on the lower side holder via a spring element. Variations and modifications of the illustrated embodiment are possible without departing from the scope of the invention as defined in the following claims.
