Description

The invention relates to a Sonnenschutzbehang with the features of the preamble of claim 1.

A slat for another purpose, namely a roller shutter slat for building a roller shutter is already by the DE 103 27 451 B4 known.

The known roller shutter slat has a substantially smooth rear side, a lower side which contains an undercut groove which extends substantially over the entire length of the slat, an upper side which carries a connection strip, which forms a positive fit with the groove on the underside of another slat is connected and which is designed such that the connecting bar in the longitudinal direction of the groove in this insertable but in the transverse direction of the groove is not removable from this, on. In addition, light slots are provided in the connection bar.

A built-up from the known roller shutter slats roller shutter is relatively unstable and wind-prone. In particular, it can come when a force in the horizontal direction on a lamella for deformation of the roller shutter. Such roller shutter armor can therefore be made only in small widths.

From the US 2005/0205223 A1 For example, a sunshade curtain is known which has lamellae which have a coupling portion at one end and a cavity for receiving a coupling portion of another sunshade lamination at the opposite end. The coupling portion is hook-shaped. In the cavity for coupling shoulders are provided, on which the coupling portion can be supported.

The DE 18 04 509 discloses a roller shutter formed of box members having above a wing provided with ventilation openings and a downwardly open channel adapted to receive the wing of the underlying element. One of the edges of the channel has a downwardly directed extension which, in the extended position of the shutter, shields the openings and is adapted to face the wing of the shutter to arrange the element underneath so as to avoid the direct ingress of light and still allow the passage of air through the openings of the sash.

The GB 2 105 396 A discloses a roller shutter having blades that are hinged together.

Object of the present invention is to provide a Sonnenschutzbehang with great wind stability.

This object is achieved according to the invention by a Sonnenschutzbehang according to claim 1. Thereby, the coupling portion and the cavity of two coupled sunblinds are coordinated so that the coupling portion of a sunshade in the cavity of the other sunshade with unwound by the sunblinds formed Sonnenschutzbehang horizontally perpendicular to the longitudinal direction the sunblind is arranged without play to achieve a stiffening, in particular perpendicular to the plane of a developed Sonnenschutzbehangs, which is formed from the sunblinds.

It is understood that "play-free" is to be understood in the sense that the lamellae are coupled substantially free of play within the scope of the manufacturing tolerances. A swivel movement must also be possible in order to be able to roll up a curtain made of sun protection slats.

Due to the play-free arrangement with unwound (hanging) Sonnenschutzbehang the coupling portion is flat or at least at several points inside the cavity of the other Sunblind on. The sunblinds thus mutually stiff, with the result that a Sonnenschutzbehang having one or more of the blades according to the invention is wind resistant and can be realized and used in larger widths. Due to the mutual stiffening of the sunblinds, it is possible to make the sunblinds very thin. This in turn causes that small winding diameter of the wound Sonnenschutzbehangs can be realized.

One or more projections may be provided in the cavity for engagement with the coupling portion of a coupled solar shading. Alternatively or additionally, one or more projections may be provided on the coupling portion, which may rest against the cavity wall of the coupled sunshade lamella. The projections can cause a flat, punctiform or linear system. Preferably, at least one projection is aligned in a straight line parallel to the longitudinal direction of the lamella. This results in a particularly good stiffening.

Further, it is conceivable that the projection or projections are arranged in the cavity so that they rest against a rear side of a hook-shaped coupling portion of a coupled sun protection lamella.

In other words, the coupling portion of a coupled sunblind and the cavity with projection of a sunblind are coordinated so that the coupling portion within the cavity can not be moved horizontally perpendicular to the longitudinal direction, but only a pivoting movement is allowed. Preferably, the projection or projections are arranged on a wall delimiting the cavity.

The lamellar body having the cavity for receiving a coupling portion of a coupled sunblind and the coupling portion of the coupled sunblind are further coordinated so that a detachment of the coupled blade by a pivoting movement is not possible.

A projection is formed as the bottom of a bead arranged in the cavity wall. Such a bead stiffens the sunblind in addition. In addition, a bead can be relatively easily introduced. For example, the bead can be introduced into the cavity wall by roll forming. In principle, however, it would also be conceivable to produce the sunshade lamella in an extrusion molding process and, to that extent, to form the projection or a bead.

Advantageously, the bead extends over the entire length of the sunblind. This creates a stiffening over the entire length of the sunblind and a Sunschutzbehangs thus constructed.

According to a further advantageous embodiment of the invention can be provided that the projection is provided spaced from an opening edge. The projection is thus not directly at the opening of the cavity, but is offset from the opening of the cavity upwards. This has the advantage that the pivot point for the pivoting movement of two coupled sunblinds, which perform this when a sunshade curtain is wound, is not affected. In particular, the widest possible angle is thereby made possible, so that a winding of a sunshade curtain in both directions is possible and yet there is a stiffening of the curtain.

As already mentioned above, it is advantageous if the projection is formed. In particular, the projection may be formed by roll forming or extrusion. Furthermore, it is conceivable that the one or more projections are attached later, z. B. by gluing. For example, a knobbed adhesive tape could be adhered to a suitable location.

Further advantages arise when the opening is open obliquely downwards. Also by this measure, the permissible pivot range of two mutually coupled sunblinds can be increased.

According to a particularly preferred embodiment, one or more light slots may be provided above the fin body. In particular, the light slots may be arranged so that they are not covered by a coupled blade. This results in a defined light passage opening.

A particularly simple embodiment of the coupling section results when it comprises a downwardly open channel, one end of a coupling section of a coupled sunblind section coming to rest behind an upstand in the region of the opening edge. By this embodiment of a sunblind further coupling means for coupling two sunblinds are not necessary.

Advantageously, the front of the sunblind can have two obliquely oriented to the vertical portions, wherein the upper portion is flatter than the lower portion.

Advantageously, the inclined portions abut each other at an outwardly directed edge at an obtuse angle.

Particularly simple and inexpensive, a sunblind can be made by roll forming from a metal strip. Such a constructed solar shading is also very stable.

The coupling portion of a coupled sunblind and the cavity with projection of a sunblind are coordinated so that the coupling portion within the cavity can not be moved horizontally perpendicular to the longitudinal direction, but only a pivoting movement is allowed. Preferably, the projection or projections are arranged on a wall delimiting the cavity.

The first and second sunblind can be identical.

Further features and advantages of the invention will become apparent from the following detailed description of an embodiment of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The features shown there are not necessarily to scale and presented in such a way that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

In the schematic drawing embodiments of the invention are shown and explained in more detail in the following description.

The Fig. 1 shows a sunblind 1 in an end view. The sunblind 1 has a coupling section 2 and a lamellar body 3 adjoining it at the bottom. This means that the coupling section 2 starts from the lamellar body 3. The lamellar body 3 has a cavity 4, which is opened through an opening 5 downwards. The cavity 4 is adapted to receive a coupling portion 2 of another sunblind 1. In the cavity 4, in particular on a wall 6, which limits the cavity 4, a projection 7 is formed. In particular, the projection 7 is formed as the underside of a bead 8 arranged in the cavity wall 6. On the other hand, it causes a further sunblind, which is arranged with its coupling portion 2 in the cavity 4, only with respect to the sunblind 1 is pivotable, but can not be moved in the horizontal direction , Characterized in that the projection 7 is arranged at a distance from the lower edge 9 of the opening 5, it is ensured that two mutually coupled sunblinds 1 can pivot relative to each other.

Furthermore, the Fig. 1 can be seen that the opening 5 is not open vertically downwards, but is open obliquely downwards. This also affects the swivel range of two coupled sunblinds. The coupling section 2 has a neck 10 which is interrupted in sections so that light slots are present. A light slot 11 is indicated by the dashed lines 11.1, 11.2.

The coupling section 2 also has a downwardly open groove 12, wherein the end 13 comes to rest behind a raised edge 14 of another, in particular identical, sunblind 1 when they are coupled together. The end 13 represents the pivot point of the sunblind 1.

The front of the sunblind 1 has two obliquely oriented to the vertical portions 15, 16, wherein the upper portion 15 is flatter than the lower portion 16. In particular, the portions 15, 16 abut at an outwardly directed edge 17 at an obtuse angle to each other.

Furthermore, the front side has a vertical section 18. The underside 19 of the sunshade louver has an angle to the horizontal of> 15 ° in order to achieve shading of the light slots of a connected sunshade louvre when the sun is high.

Of the Fig. 1 It can be seen that the sunblind is designed in two sections in certain sections. This makes it clear that the solar shading shown is made of a metal strip by roll forming.

The Fig. 2 shows a Sonnenschutzbehang 30, which is composed of four sunblinds 1.1, 1.2, 1.3, 1.4, wherein the sunblinds 1.1 - 1.4 are identical and each of the coupling portion 2 of a sunblind 1.1 - 1.4 in a cavity 4 of a lamellar body 3 of an adjacent sunblind 1.1 - 1.4 is arranged. Here it can be seen that the projection 7 rests against the coupling portion 2 at a point where the neck 10 merges into the downwardly open channel 12. The end 13 lies In contrast, in the bending region 20 of the upstand 14. The coupling portion 2 is thus fixed in the cavity 4 at opposite locations. A relative movement of two connected sunblinds 1.1 - 1.4 in the horizontal direction perpendicular to the longitudinal direction is not possible, since the distance between the projection 7 and the bending region 20 is the smallest distance within the cavity 4.

It should be noted at this point that the sunshade curtain 30 is not intended to abut with the lowermost sunblind and to vertically shift the slats together. So it is not a roller shutter.

Of the Fig. 3 it can be seen that two interconnected sunblinds 1.1, 1.2 are pivotable relative to each other.

In the Fig. 4 it is shown that pivoting in the opposite direction is also possible. By virtue of the fact that two sun protection lamellae 1.1, 1.2 which are coupled to one another can be pivoted relative to one another in two directions, it is possible to wind up a sunshade hanger 30 both in the clockwise direction and in the counterclockwise direction.

Of the Fig. 5 can be seen that in a further pivoting compared to the representation of Fig. 4 the portion 10 of the sunblind 1.2 on the bottom 19 abuts. Here is the pivot point opposite the representation of Fig. 4 shifted to the left. Of the Fig. 5 It can be seen that it is not possible to separate by relative pivoting of two sunblinds 1.1, 1.2, the two Sonnenschutziamellen. To connect and disconnect two sunblinds 1.1, 1.2, it is necessary to move the sunblinds in the longitudinal direction relative to each other.

The Fig. 6 shows a front view of a Sonnenschutzbehangs 30, which is composed of several sunblinds 1, 1.1 - 1.4 according to the invention. It can be seen here that the sunshade curtain 30 has a uniform optical structure.
