Abstract

The shutter has two lamellas (1) connected with each other by an intermediate lamella (2), which is hingedly mounted at edges of the lamellas. Openings (3) are formed between the lamellas and changeable based on pivoting of the lamellas in a position. The intermediate lamella is designed with a circular cross-section as a hinge strip (6) at the edges, where the hinge strip engages into a hinged hook (4) of the lamellas. A stop segment (7) is formed at the hinge strip and positioned in a groove (5) of the hinged hook.

Description

The invention relates to a glare protection roller shutter according to the preamble of claim 1.

Such anti-glare shutters, which also form an extensive privacy in lowered position, are known in many designs.

Thus, a construction is used, in which the individual lamellae are kept apart by flexible bands, while the simultaneous pivoting of the lamellae is effected by a cable pull. A comparable anti-glare shutter is in the DE 20 2007 000 744 U1 revealed.

A different variant is in the DE 20 2005 010 548 U1 thematized, in which a substantial part of the slats are formed as see-through slats with window openings, which, depending on the position, can be covered by a cover slat, each of these cover slats is hingedly connected in the region of a longitudinal edge with two adjacent slats.

However, the production of such a blind thread is very complex and therefore expensive, even if the profiles are produced in the extrusion process.

This applies equally to an anti-glare shutters in the DE 1 237 289 A1 however, in which only the fins are referred to as formed on both sides with a cover-carrying intermediate plate as part-slats, between which a closable by an attached to an intermediate plate cover plate opening is formed. Again, especially the production of the intermediate blade with attached cover strip is very expensive, since the cover must be materially connected to the intermediate plates.

A deviating from the genre anti-glare shutters are the DE 29 32 010 A1 again. In this case, two adjacent, not pivotable about a horizontal axis slats are always connected by an intermediate plate which has window openings and which in the closed position can be inserted into an associated slat so that it covers the window openings, so that overall results in a largely flush-mounted roller shutter, which then no longer allows light and no transparency.

Apart from the unsatisfactory regarding a glare protection function, this shutter, as well as the previously named, relatively expensive and expensive to manufacture.

The invention has the object of providing an antiglare shutter of the generic type so that with little design effort a simple and cost-effective production is possible and its function is improved.

This object is achieved by a glare protection roller shutter with the features of claim 1.

In addition to the design and manufacturing technology very simple and cost-effective implementation of the new anti-glare shutter is a purely functional optimal use of einstrahlendem sunlight depending on the desired glare and privacy protection possible.

Preferably, the intermediate plate extends approximately over the length of the slats with which the intermediate plate is connected, in which case the Zwischenfamelle has at least one, preferably a plurality of apertures, which may be in the form of windows or as a perforation, ie, sieve-like. Although the intermediate plate, to fulfill its intended function, also consist of two or more individual pieces which are hinged independently of each other on the outer edge of the blade, to form the openings. However, the one-piece variant of the intermediate blade is preferable because it provides greater stability of the overall system.

According to the invention, the spatial position of the apertures formed by the apertures is dependent on the pivoting of the slats, these openings, based on the vertical, are in a freely inclined position of the shutter at a steeper angle than when mounted on the basis of blinds. In this case, the slats are pivoted by their own weight so that the openings of the intermediate slats are at a shallower angle to the vertical.

In this case, the pivoting of the slats and consequently the intermediate slats is limited at a predetermined angle, for which purpose the intermediate slats and the slats are modified in their common hinge region in a manner as will be described later.

While in a free-hanging position of the anti-glare shutter the openings of the intermediate plates are so exposed that a double-sided view is possible, which can be used, for example, winter sunlight for lighting and to improve solar heat gains. Direct solar radiation in summer, with a high angle of incidence is reflected or directed into the interior of a building, the roller shutter forms a temperature buffer, in the sense of shading.

In attached position of the shutter, wherein the bottom lamella rests on the ground and in which all lamellae are in the end position, who covered the openings so far by the scale-like lamellae that although a privacy from outside to inside, however a view from inside to outside is at least possible. The intermediate blades are inclined against the horizontal direction of insight.

The respective intermediate blade is formed at its parallel, the blades associated edges each as a hinge bar, the form-fitting, but rotatably rests in a hinge hook of the blade.

To limit the pivot angle, a stop web is integrally formed on the hinge, which engages in a groove of the hinge hook of the blade, wherein the groove defining lateral walls form a pivot boundary for the intermediate blade.

A change in the geometry of the slats or the intermediate slats, in particular the distances between the joint hooks of the slats and hinges of the intermediate slats to each other changed the light. An increase in the distances of the hinges can magnify the review in the closed position of the shutter, with the same opening size.

Depending on your requirements, the opening size, the light control, the sunblind and the transparency can be adjusted so that a control of the solar heat gains and a reduction of the cooling loads for different climate zones is possible.

The optimum for lowering the cooling load and use of solar heat gains angle between the lower edge of an upper fin and the upper edge of the associated lower fin in freely suspended, so unsupported shutters is 15 ° -30 °, preferably 25 °.

The leadership of the shutter in lateral, fixed rails, which are located in the area of the soffit of a building opening, can be done by direct insertion of the slats. It is also conceivable, however, to provide the lamellae and / or the intermediate lamellae with guide pins which, relative to the cross section, are arranged centrally on the lamellae or the intermediate lamellae and which engage in the rails.

With regard to the shading function, demands are made, moreover, for limiting the gap formation between the associated slats in an upper partial area, for example, independently of the position of the roller shutter, in order, for example, to keep constant. an optimized shading in this area, ie a narrowness of the slats to one another, even when the remaining slats occupy a so-called open position with freely hanging roller shutter.

For this purpose, the fixedly positioned to each other slats can be interconnected by a coupling member, for example in the form of a rod with the slats in question is connected and by a relative movement of the slats is prevented from each other.

Another variant provides that the slats of the sub-area are connected by a rod with a flexible element, such as a belt, which is dimensioned in length so that on the one hand in freely suspended blinds, the relative movement of the slats in the sense of a pulling apart not is possible. Upon discontinuation of the shutter, however, the slats of the sub-area, as described, move in a scale like each other, so that they occupy the same closed position as the other slats.

In both cases it is sufficient to couple only the slats together, without the involvement of the intermediate slats.

Further advantageous embodiments of the invention are characterized in the subclaims.

Embodiments of the invention will be described below with reference to the accompanying drawings.

FIG. 4

a further embodiment of the anti-glare shutter, in a schematic side view.

In the FIGS. 1 and 4 FIG. 2 shows an anti-glare shutter closing a building opening, which has a plurality of horizontally oriented slats 1 which are mounted in lateral, fixed rails 9 (FIG. FIG. 4 ) are guided.

The closed visible surface having slats 1 are pivotable about a horizontal axis, as shown by in the FIG. 4 Guide pins 10 are formed, which are mounted in the rail 9 and which are attached to the slats 1.

According to the invention, between these two slats 1, an intermediate slat 2 connecting them to one another is arranged, which, like the FIG. 3 reproduces very clearly, has openings 3, which are variable depending on the pivoting of the slats 1 and the intermediate plate 2 in position.

For articulated connection of the intermediate plate 2 with the associated slats 1, the intermediate plate 2 at their longitudinal edges in each case a hinge bar 6, which is circular arc-shaped in cross-section and to which a stop web 7 is integrally formed.

The hinge bar 6 is engaged with a matched to the cross-section of the joint hook 4 of the blade 1, in which the hinge bar 6 engages.

To limit the pivot angle between the intermediate plate 2 and the slats 1, a groove 5 is provided in the articulated hook 4, in which the stop web 7 rests, wherein the opposite walls of the groove 5 form a stop surface for the stop web. The width of the groove 5 is of course greater than the width of the stop web. 7

In the FIG. 1 two different positions of the anti-glare shutter are shown. On the left side of the anti-glare shutter is hanging freely, ie, it is not supported on a substrate 8, in contrast to the right-hand representation, in which the lower blade 1 rests against the substrate 8.

In the left-hand view, the greatest possible transparency through the openings 3 is given to the outside, this being determined by the distance "X" between two slats 1.

An external view, which is illustrated by the arrow shown, is also possible, wherein the width of a slot formed is indicated by "a". The review takes place here in the horizontal direction, while the review by the gap "X" from top to bottom.

Depending on the tilt angle, but also on the height of the openings 3 is the light from outside to inside, in the FIG. 1 is specified with the angle α and determines the degree of shading.

The angle of incidence α should be provided in a range of 15 ° - 30 °, preferably 25 °.

When in the FIG. 1 the right side seen closed position of the anti-glare shutter so far take the slats 1 as well as the intermediate plates 2 an end position in which the stop ridge 7 rests against the one wall of the groove 5. In this position, an outward view at a distance "Y" is given, while a view inward, at least in the horizontal direction is not possible, as illustrated by the line b.

In the FIG. 4 Finally, in this case, three upper slats 1 are rigidly connected to each other by a coupling rod 11 which is fixed to the guide pin 10.

Regardless of how the other, mutually pivotable slats 1 are positioned, comparable to the illustrations in the FIG. 1 , A distance c between the rigidly interconnected slats 1 in each case remains the same, which, for example, a constantly reduced incidence of light can be achieved.

Incidentally thereof, the lamellae 1, as well as the intermediate plates 2 in their cross-section mirror-symmetrical design, resulting in a particularly simple and cost-effective production results and also a replacement of the fins 1 is easily possible.
