DESCRIPTION

Sun protection curtain

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

A slat for another purpose, in particular, a roller blind slat for the formation of a roller blind cloth has already been known from DE 103 27 451 B4.

The known roller blind slat has an essentially smooth rear side, a lower side, which contains a recessed groove that extends essentially along the entire length of the slat, an upper side, which carries a connecting strip, which is connected with a drag with the groove on the lower side of another blade and which is formed in such a way that the connecting strip can be fitted therein in the longitudinal direction of the groove but cannot be removed therefrom in the transverse direction of the groove . In addition, light slots are provided in the tie bar.

A roller blind cloth constructed from known roller blind slats is relatively unstable and susceptible to wind. In particular, under the action of forces in a horizontal direction on a slat, deformation of the roller blind cloth occurs. Roller blind cloths of this type can therefore be produced only in small widths.

From US 2005/0205223 A1 a sunscreen curtain is known which has slats having at one end a coupling section and at the opposite end a cavity for housing a coupling section of another sun protection strip. The coupling section is formed in the form of a hook. Projections on which the coupling section can be supported are provided in the cavity for coupling.

Document DE 18 04 509 discloses a rolling shutter that is formed by box elements that have a wing above that is provided with ventilation openings, and an open downward channel, which is suitable to accommodate the wing of the element located below . One of the edges of the channel has a downwardly directed extension which, in a stretched position of the roller shutter, shields the openings and is suitable for arranging the element that is below in front of the wing so as to prevent the direct penetration of the light and, despite this, the passage of air through the openings of the wing is allowed.

Document GB 2 105 396 A discloses a roller blind that has slats that are joined together in an articulated manner.

It is an object of the present invention to provide a sun protection curtain with great wind resistance.

This objective is achieved in accordance with the invention by means of a sun protection curtain according to claim 1. In this way, the coupling section and the cavity can be adjusted to each other by two sun protection slats coupled so that the section The coupling of one sun protection blade is arranged without strike in the cavity of the other sun protection blade in the case of the unrolled sun protection curtain formed by the sun protection slats, horizontally perpendicular to the longitudinal direction of the slats of sun protection, to achieve a reinforcement, in particular perpendicular to the plane of an unrolled sun protection curtain, which is formed by the solar protection slats.

It is understood that "without strike" is to be understood in the sense that the slats are essentially coupled without strike in the context of manufacturing tolerances. An oscillating movement must also be possible to be able to wind a curtain built by solar protection slats.

By means of the arrangement without strike in the case of the unrolled sunscreen curtain (hanging), the coupling section is supported flat or at least in several places inside the cavity of the other sun protection strip. The sun protection slats are therefore mutually reinforcing, with the consequence that a sun protection curtain, which has one or more of the slats according to the invention, is wind resistant and can be made and used in wider widths. By means of the mutual reinforcement of the solar protection slats it is possible to make the solar protection louvers in a very thin way. This in turn causes small winding diameters of the rolled sun protection curtain to be made.

One or more projections may be provided in the cavity to come into contact with the coupling section of a coupled sun protection strip. Alternatively or additionally, one or more projections can be provided in the coupling section which can be supported on the cavity walls of the coupled sun protection strip. The projections can cause a flat, punctual or linear contact. Preferably, at least one projection is oriented in a straight line parallel to the longitudinal direction of the blade. This results in an especially good reinforcement.

In addition, it is conceivable that the projection (s) are arranged in the cavity so that they rest on a rear side of a hook-shaped coupling section of a coupled sun protection strip.

In other words, the coupling section of a coupled sun protection strip and the protruding cavity of a sun protection blade are adjusted to each other so that the coupling section within the cavity cannot move horizontally perpendicular to the longitudinal direction, but only an oscillating movement is allowed. Preferably the projection (s) are arranged in a wall that delimits the cavity.

The slat body, which has the cavity to accommodate a coupling section of a coupled sun protection strip and the coupling section of the coupled sun protection blade, are also adjusted together so that it is not possible for the coupled blade to be disengage due to oscillating movement.

A projection is configured as the bottom side of a groove disposed in the cavity wall. A groove of this type further reinforces the sun protection strip. In addition, a groove can be incorporated relatively easily. For example, the groove in the cavity wall can be incorporated by rolling forging. In principle, however, it would also be conceivable to produce the solar protection strip in the extrusion pressing process and, in this sense, to form the projection or a groove.

Advantageously, the groove extends along the entire length of the sun protection strip. In this way, a reinforcement is generated along the entire length of the sun protection strip and a sun protection curtain constructed from it.

According to a further advantageous configuration of the invention, it may be provided that the projection is provided separately from an opening edge. Therefore, the projection is not directly in the opening of the cavity, but is displaced upwardly with respect to the opening of the cavity. This has the advantage that the pivot point for the oscillating movement of two coupled sun protection slats, which perform the same, is not affected when a sun protection curtain is wound. In particular, in this way an angle as large as possible is allowed, so that a winding of a sunscreen curtain in both directions is possible and, consequently, a curtain reinforcement takes place.

As already mentioned above, it is advantageous when the projection is molded. In particular, the projection may be molded by rolling forging or extrusion pressing. It is also conceivable that the protrusion (s) are subsequently incorporated, for example by means of gluing. For example, an adhesive tape of buttons could be stuck in suitable places.

Other advantages result when the opening is open diagonally downwards. Also by means of this measure, the permitted oscillating zone of two solar protection slats coupled to each other can be extended.

According to an especially preferred embodiment, one or more light slots may be provided above the slat body. In particular, the light slots may be arranged so that they are not covered by a coupled slat. Therefore, a defined light passage opening results.

An especially simple configuration of the coupling section results when it comprises a groove open downwards, one end of a coupling section of a sun protection blade coupled behind a edge in the area of the opening edge becoming in contact. . By means of this configuration of a sun protection strip, no other coupling means are necessary to couple two sun protection slats.

Advantageously, the front side of the sun protection blade can have two sections oriented diagonally with respect to the vertical, the upper section running more flat than the lower section.

Advantageously, the inclined sections limit with a ridge directed outward at an obtuse angle.

In a particularly simple and economical way, a solar protection strip can be produced by forging by rolling from a metal strip. A solar protection strip constructed in this way is also especially stable.

The coupling section of a coupled sun protection blade and the projection cavity of a sun protection blade are adjusted to each other so that the coupling section within the cavity cannot move horizontally perpendicular to the longitudinal direction, but only an oscillating movement is allowed. Preferably, the projection (s) are arranged in a wall that delimits the cavity.

The first and second solar protection slats can be configured identically.

Other features and advantages of the invention result from the following detailed description of an exemplary embodiment of the invention, by means of the Figures of the drawing, which show essential details for the invention, as well as the claims. The characteristics shown there are not necessarily to be understood at scale and are represented in such a way that the particularities can be clearly explained according to the

invention. The different characteristics can be realized in each case individually or in several in any combination in the variants of the invention.

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

They show:

a representation that shows the possibility of oscillation in the opposite direction; a representation from which it is explained that a solar protection strip cannot be hung; a top view of a sunscreen curtain of the solar protection slats according to the invention.

Figure 1 shows a sun protection strip 1 in a front side view. The sun protection blade 1 has a coupling section 2 and a blade body 3 which is attached below it. This means that the coupling section 2 exits the slat body 3. The slat body 3 has a cavity 4 that is open from below through an opening 5. The cavity 4 is formed to accommodate a coupling section 2 of another slat of sun protection 1. In the cavity 4, in particular in a wall 6, which delimits the cavity 4, a projection 7 is formed. In particular, the projection 7 is configured as the bottom side of a groove 8 arranged in the cavity wall 6 The protrusion 7 causes, on the one hand, a reinforcement of the sun protection strip 1. On the other hand, this causes that another sun protection blade, which is arranged with its coupling section 2 in the cavity 4, can pivot only with respect to to the sun protection strip 1, but cannot move in a horizontal direction. Because the projection 7 is arranged with a distance from the lower edge 9 of the opening 5, it is guaranteed that two sun protection slats 1 coupled to each other can pivot with respect to each other.

In addition, it appears from Figure 1 that the opening 5 is not open perpendicularly from below, but is open diagonally downwards. This also has an impact on the pivoted zone of two coupled sun protection slats. The coupling section 2 has a neck 10 that is interrupted by sections, so that light slots are present. A light slot 11 is indicated by the dotted lines 11.1, 11.2.

The coupling section 2 also has a groove open downwards 12, the end 13 resting behind a edge 14 of another sun protection strip 1, in particular identical, when they are coupled to each other. The end 13 represents the oscillating point of the sun protection strip 1.

The front side of the sun protection strip 1 has two sections oriented diagonally with respect to the vertical 15, 16, the upper section 15 running more flat than the lower section 16. In particular, sections 15, 16 border with a directed edge out 17 at an obtuse angle.

In addition, the front side has a vertical section 18. The lower side 19 of the solar protection strip has an angle with respect to the horizontal of> 15 °, to achieve a shadow effect of the light slots of a protection strip solar united with the sun in high position.

Figure 1 shows that the sun protection plank is configured in two layers in certain sections. In this way it is explained that the sun protection strip shown is produced from a metal strip by means of rolling forging.

Figure 2 shows a sun protection curtain 30, which is constructed by four solar protection slats 1.1, 1.2, 1.3, 1.4, the solar protection lamas 1.1 -1.4 being formed identically and the section of each being arranged in each case. coupling 2 of a sunscreen 1.1-1.4 in a cavity 4 of a blade body 3 of an adjacent sun protection blade 1.1 - 1.4. In this case it can be seen that the protrusion 7 in the coupling section 2 rests on a site where the neck 10 passes to the groove 12 opened below. The end 13 is instead in the buckling zone 20 of the edge 14. The coupling section 2 is therefore fixed in the cavity 4 in opposite places. A relative movement of two solar protection slats joined 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 buckling zone 20 is the smallest distance within the cavity 4 .

At this point it should be noted that the sun protection curtain 30 is not intended to be limited to the lower sun protection blade and the slats slide vertically inside each other. That is, it is not a rolling shutter wrap.

From Figure 3 it can be seen that two solar protection slats joined together 1.1, 1.2 can pivot with respect to each other.

Figure 4 shows that pivoting in the opposite direction is also possible. Because two solar protection slats coupled to each other 1.1, 1.2 can pivot in two directions relative to each other, it is possible to wind a sun protection curtain 30 both clockwise and counterclockwise. clock hands

5 From Figure 5 it can be deduced that with an additional pivot with respect to the representation of Figure 4, section 10 of the solar protection strip 1.2 is supported on the lower side 19. In this case, the pivot point has been shifted to the left with respect to the representation of Figure 4. From Figure 5 it follows that it is not possible to separate the two sun protection slats by relative pivoting of two sun protection slats 1.1, 1.2. To join and also separate two solar protection slats 1.1, 1.2 it is necessary to move the solar protection slats in longitudinal direction with respect to each other.

Figure 6 shows a front view of a sun protection curtain 30, which is constructed by several solar protection slats according to the invention 1, 1.1-1.4. It can be seen in this case that the sun protection curtain 30 has a uniform optical structure.
