Fabric material for sun visors and visors made therefrom

The invention relates to a ffewebematerial, the woven, includes rods that are closely adjacent to one another and is used to manufacture roll-up sun visors in the manner of shutters, as well as panels from it.

There is an inclination and a need for ever greater nowadays Window areas and more windows, the problem of solar radiation and solar heat takes on the importance as well as the glare protection accordingly.

Various devices are commercially available to solve this problem and to combat the difficulties. These include curtains, Venetian blinds or shutters, roll-up blinds made of cotton or fabric, ba

bus, plastic, wood, etc. Hit except for the venetian! see bezels or shops, all of these devices reduce visibility and so too the air passage through the material proportional to that Protection they provide while the Venetian dazzles are in the generally affect the appearance of the window surfaces and are ugly to look at.

The object of the invention is basically to provide a material that can be used as a rollable screen material, but nonetheless allows air to pass through the Keeps material free and allows adequate visibility while providing protection from direct sunlight and providing a allows adequate passage of light.

According to the invention, a fabric material is provided that each other closely spaced rods, which are held at a certain distance from one another by means of a woven, flexible bond which is generally at right angles to the length of the rods, with the sides of the rods at a suitable angle stand to the side surfaces of the assembled material and the edges of the rods face the side surfaces of the material, respectively.

! times a further feature of the invention rods are provided, which support each other in pairs by means of a bond that interweaves or connects the rods, whereby ·! the Pairs by bonding themselves at a certain distance from each other are held, and that the individual members of a pair in turn with individual members of the next pair of tissue are connected * in spaced intervals along the bars.

The material consists essentially of rods as Seattles and from a chain or from corresponding warp threads. You can rods consist of wood, plastic, metal or another suitable material and have a width, bead and shape, which are suitable for the desired effect · The warp or the warp threads can consist of any suitable binding material. Each pair of binding yarns can be crossed between the rods or twisted one or more times as desired

Width of the spaces between the bars. If thin, narrow Rods made of white, translucent plastic close together with a chain are woven or linked from thin yarn, the result is a blouse, that is almost invisible, but provides the highest level of protection and hardly obstructs the view, just like that Air and light passage through the material. If you have rods with used inclined edges, the side surfaces run obliquely to the side surfaces of the panel material, whereby a larger Protect against sun exposure towards evening or do a similar Time is reached.

Preferred embodiments of the invention are referred to below of examples explained in more detail with reference to the accompanying drawings. Show in the drawings

Pig. Fig. 2 is a sectional view taken along line A-A of Fig. 1;

Figure 3 is a sectional view through the fabric taken along line B-B of Figure 1;

At this point it should be noted that the subject of the invention is not only the types of fabric described in more detail below, but also light and sun visors made from them, their fabric course corresponds to that of the fabric according to the invention.

In a preferred embodiment according to the invention, which is shown in Fig. 1, comprises the fabric material for manufacture a sun visor narrow wooden rods 1, for example having a thickness that is between a quarter or a half their width liqgt.

The rods 1 consist of mutually supporting pairs, which are denoted by the reference numerals 1a and 1b, the Support by means of spaced pairs of plastic strips or other suitable flexible strips or yarn threads 2 are brought about, which either cross between each pair of rods, as shown in Fig. 4, or one

as are twisted eel or several times between each pair, / in Fig. 5 and 7 is shown. The arrangement is such that each pair of strips between the rods wraps around each pair of rods and the crossed or twisted parts or portions of the strips serve to keep the pairs of rods at a specified distance to hold to each other.

The pairs of strips 2 generally extend to the right Angle to the length of the rods, and the pairs of strips are also spaced appropriately from each other to to achieve and maintain a uniform spacing of the rods over the entire surface of the fabric material.

The rod pairs are arranged in such a way that the edges of the rods point outwards and the sides consequently run in planes, which are at right angles to the side surfaces of the composite material as shown in Figures 2-5.

The arrangement of the bars, with their edges corresponding to the side surfaces facing the assembled material is achieved by that the weave is woven in such a way that a pair of rods is connected at intervals, one rod of this pair being connected to a Rod of the closest pair is connected between these intervals.

The bars therefore form a zigzag pattern between the pairs of binding strips, and this increases the pitch of the bars

00985 1/08 57

suppressed to take a position other than that at which their edges face the side surfaces of the fabric material.

When two or more pairs of adjacent binding strips are used as binding of the same two rods are arranged in a pair, these rods cross the gap to the adjacent pair of rods only where the adjacent pair of tie strips binds one rod of that pair into a pair with a rod of the next pair. In this way raster effects and ornaments can be formed.

Such a modified embodiment is shown in fig. 7 shown, where three pairs of adjacent binding strips are used are to tie the same pair before tying one link of that pair to a link of the next pair of rods is.

If you let the edges of the bars run at an angle, they can be arranged so that the sides of the bars are at an angle other than a right angle to the side surfaces of the composite material, which embodiment is shown in FIG. In both cases the effect becomes one Venetian aperture achieved.

It should be noted that the fabric material that is described above in the exemplary embodiments is woven in such a way that the rods are used as wefts and the tie as a chain.

The rods can be made of any opaque or translucent you want or translucent strip material including plastic and metal. The width and the thickness of the Rods, as well as the type and strength of the bond, can vary within a wide range depending on the requirements. The requirements are based on the required appearance, the degree of air permeability, the extent of the desired shielding, the degree of transparency and the possibility of preventing insects from entering.

In this context it should be pointed out that both fine

as well as coarse material can be woven to fabric material for diaphragms with the advantages of a Venetian diaphragm but with the aforementioned additional advantages.
