Description

The invention relates to an extendable sunshade, in particular awning, for attachment to building structures, especially above buildings and conservatories, with a towel roll unrollable cloth, the front end is attached to an extension profile, as well as at least two guide rails on which sliding parts guided are.

For shading a building structure, such as a conservatory or a pergola, it is known to attach to this construction a retractable sunshade. It is desirable to make the sunshade so that it protrudes laterally and in the extension direction on the building structure to provide protection against oblique incident solar radiation. From the DE 197 17 654 and the DE 40 15 995 It is known to make the Ausfahrprofil so wide that the awning covers the guide rails far on both sides. In contrast, the area on the front is not or only slightly surmounted.

From the DE 102 12 027 C1 is known, a window awning with a winding shaft with awning, a deflection for the awning and a connected to the lower end of the awning drawbar. The deflection shaft is mounted on both sides in guide rails. Ausstellelemente serve to extend the drawbar in the lowered position of the pulley.

It is provided that the release elements are designed as articulated arms, wherein the respective articulated arm is articulated with one end in a bearing part, which is slidably mounted in the guide rail facing this, and the other end of the articulated arm is articulated in the tie rod.

Such an awning can be covered with minimal construction effort, for example by the cassette in its retracted position not visible. In the extended state of the awning no disturbing components are positioned between the drawbar and the post of a window to be shaded.

From the EP 1 199 422 A1 is a freely suspended Gelenkarmwnise known in which an extension profile by means of the articulated arms is extendable and on the Ausfahrprofil lever arms for extending a second Ausfahrprofils are arranged.

From the FR 1 453 870 is a free-hanging awning with lever arms instead of articulated arms known.

The object of the invention is to improve a sunshade of the type mentioned so that with simple design and handling and low height, an arbitrarily far in the extension beyond the building construction projecting area is covered and shaded, which is arbitrarily far in the sense to understand in that the projecting area is not restricted by, for example, the length of the guide rails or the distance between the guide rails.

This object is achieved in that at least one lever arm is arranged on each guide rail, whose first end is hinged to the sliding rail along the guide rail, in particular carriage, and whose second front end is articulated on the Ausfahrprofil along the Ausfahrprofils movable or in that at least one articulated arm is arranged on each guide rail, whose first end is articulated on the sliding part movable along the guide rail, in particular carriage, and whose second front end is articulated on the extension profile, so that the sunshade at least in the fully extended state in the extension over the guide rails protrudes, and wherein the sliding parts or carriages are driven on the guide rails by drive means and the lever arms or articulated arms are acted upon by tension or compression springs.

It is particularly advantageous that the sliding parts are movable on the guide rails by means of this drive means along the guide rails.

As a result, the extension profile of the sunshade with the cloth in the extension direction on the front end of the guide rails and thus also on the front end of the building, such as a winter garden, are driven out, so that the sunshade towers far beyond the conservatory in the extension, so that the Front of the object is shaded against obliquely incident solar radiation and also a shading of the square in front of the construction, such as a terrace, is possible. Here, the simple construction requires no greater height. The extension of the sunshade according to the invention, that is, the projecting beyond the building area, is not limited by, for example, the length of the guide rails or the distance between the guide rails.

Further advantageous embodiments of the invention are given in the dependent claims.

When using lever arms, it is proposed that each of the movable along the extension profile front ends of the lever arms is guided in a respective guide in the Ausfahrprofil, the guides of several lever arms in the Ausfahrprofil can be arranged one above the other, so that the travel paths of the ends of the lever arms can overlap.

The lever arms or articulated arms can be acted upon by coil springs or gas springs.

In a preferred embodiment, the pivot plane of the lever arms or articulated arms relative to the plane of the guide rails is inclined in particular downwards.

The sliding parts on the guide rails can be driven by a circulating traction means, a rack / pinion gear, a threaded rod or a cylinder-piston unit and be moved along the guide rails by means of this drive means.

The end position of the sliding parts on the guide rails can be defined by a travel limit of the drive means. Alternatively, the end position of the slide parts on the guide rails may be defined by an end stop on the guide rails.

In the fully extended state, the sunshade protrudes in the extension direction beyond the building construction, in particular a winter garden.

Preferably, the sunscreen protrudes beyond the building structure at least to one of the two sides, so that the building construction is protected on the front side and / or laterally against obliquely incident solar radiation.

The sliding parts run on the side facing away from the roof of the guide rails, so that the sun protection is mounted overall above the building construction, in particular the conservatory.

Embodiments of the invention are shown in the drawings in perspective view and will be described in more detail below.

On top of a building construction 1, in particular a winter garden, at least two guide rails 2, 3 are mounted. The guide rails 2, 3 may alternatively be formed by the building structure 1 itself.

Above the building structure 1, an extendable sunshade 4, in particular an awning, is provided with a cloth 5 which can be unrolled by a cloth roll and whose front end is fastened to an extension profile 6. On the guide rails 2, 3 sliding parts are guided movable. On each guide rail 2, 3, a lever arm 7, 8 is arranged, whose first end 9, 10 is articulated on the sliding rail along the guide rail, in particular carriage, and whose second front end 11, 12 articulated on the Ausfahrprofil 6 along the Ausfahrprofils 6 movable is. The sliding part movable along the guide rail 2, 3, to which the first end 9, 10 of the lever arms 7, 8 is articulated, can also be formed in that the articulation bolt of the lever arms 9, 10 is movably guided in the guide rail 2, 3. so that can be dispensed with an additional component such as a carriage.

Preferably, each of the movable along the extension profile 6 front ends 11, 12 of the lever arms 7, 8 is guided in each case a guide, wherein the guides of a plurality of lever arms 7, 8, preferably in the Ausfahrprofil 6, are arranged one above the other, so that the traverse paths along the one of Ausfahrprofils 6 movable front ends 11, 12 can cross, as in the in Fig. 3 shown, only partially extended state is recognizable.

The lever arms 7, 8 are acted upon by tension springs, in particular coil springs 13, 14, so that an extension of the sunscreen over the end of the guide rails also takes place automatically, as soon as the cloth 5 is further unrolled from the cloth roll.

The sliding parts can be driven on the guide rails by drive means, in particular a circulating traction means, a rack / pinion gear, a threaded rod or a cylinder-piston unit and be moved along the guide rail 2, 3 by means of such a drive means.

The end position of the sliding parts on the guide rails 2, 3 can be defined by a travel limit of the drive means or alternatively by an end stop on the guide rails 2, 3rd

In the fully extended state of the sun protection projects in the extension direction on the building structure 1, so that the building is protected against oblique solar radiation forward, in particular, the space in front of the building, such as a terrace, are towered by the sunscreen and thus shaded ,

Furthermore, the sunscreen may protrude beyond the building structure at least to one of the two sides, so that lateral shading against oblique solar radiation is also provided.

In a second embodiment according to Fig. 4 is at the top of a building construction 1, the two guide rails 2, 3, an extendable sunshade 4 provided with a roll-off of a cloth wraps 5. The front end of the cloth 5 is attached to an extension profile 6. At each guide rail 2, 3 at least one articulated arm 15, 16 is arranged, whose first end 17, 18 is articulated on a guide rail 2, 3 movable sliding part, in particular carriage, and the second front end 19, 20 on Extension profile 6 is hinged. By means of the articulated arms 15, 16, the sunshade can be extended over the front end of the guide rails 2, 3 and thus also over the front end of the building structure 1 in the extension direction, so that the front side of the building structure is shaded against obliquely incident solar radiation.

In Fig. 5 a third embodiment of the sunshade according to the invention, which basically has a similar structure as the embodiment according to FIG Fig. 4 has (same reference numerals designate the same components), in which case the pivoting plane of the articulated arms 15, 16 relative to the plane of the guide rails 2, 3 is inclined by an angle α down.

In a further embodiment, the lever arms 7, 8 or the articulated arms 15, 16 in the partially or fully extended state with respect to the plane of the guide rails 2, 3 can be pivoted upwards and / or downwards.

Preferably, a movable support profile may be provided as a cloth support profile 21, on which the cloth rests and is deflected in the pivoting direction. The cloth supporting profile 21 is preferably movable back and forth on the guide rails 2, 3. For this purpose, it may be attached to the sliders provided and / or on separate carriage elements.

In the fully extended state, the sunshade protrudes beyond the building structure 1 in the extension direction.

The sunshade can be dimensioned so that it projects beyond the building structure at least to one of the two sides, so that the building construction, in particular a conservatory, can also be shaded laterally against oblique solar radiation.

The first extension profile 6 preferably extends on the side of the guide rails 2, 3 facing away from the roof of the building structure 1.

The sunshade may alternatively be designed in such a way that the extension profile 6 is guided between the guide rails 2, 3 and thus lies in the plane of the guide rails 2, 3 and is limited in width by the guide rails 2, 3. In this case, the sunshade can protrude only in the extension direction on the building structure 1.

The protruding beyond the building extension of the sunshade invention is thus arbitrarily dimensioned and not dependent on the size of shaded building 1, in particular the length of the guide rails 2.3, so that the building structure 1 can be shaded in the extension direction against oblique incident solar radiation and / or a Area in the extension direction outside the building construction, such as a terrace, covered and also can be shaded.

Instead of sliding parts or slides and wagons can be arranged.
