The innovation relates to a röilöäringe FefisterflächenbespännUng, in which the rolled-up web bi1det a supply roll _s located at a Fenstarrand and can be rolled to the opposite Fensterrahd out in a desired length,

As protection against solar radiation and also against viewing by outside window areas with curtains * are usually curtains and especially with roller blinds * e.g. spring blinds. Wan = rend curtains, in addition to their decorative purpose * hardly impede the exchange of air when the window is closed and especially when the window is open * but also offer little protection against solar radiation, these conditions are practically the opposite at Rollns. They are generally quite unadorned *, darken very strongly and are almost impermeable to air. For fixing are mounting brackets to be attached to both curtains and roller blinds, to the masonry or window frame * pull and / or Roll-up mechanisms and the like are required.

As DE-GM 77 11 569, for example, a roller blind is known that one Has roller-like winding core which has a spring mechanism and wears the roller blind. The free, extendable end of the roller blind is provided with a tension rod, which is used to to hold the pulled-out sheet in a plane parallel to the window surface even on inclined window surfaces * The front ends of this Tension rods have extensions that are to be hung in hooks, which are on the side window frame spars in smaller ones or larger distances must be attached. That’s the blind more or less according to the respective light requirement the window surface can be tensioned, so it can and should be adjusted several times a day will.

Another approach is taken with the self-adhesive climate film known from DE-GM 75 07 856, which is attached to glass surfaces shall be. It is a metallized transparent film and a translucent insulating film that can be inserted or

To do this, go to the Möntäcjeseite there is also an adhesive film and, if necessary, additional = B borrowed rubber suction cups are used in the edge zones, due to the multi-layered structure Such a climate flux acts not only as a solar ^ and Thermal protection in summer, but also as thermal insulation against the cold. It can be »removed again at any time without leaving any residue on the glass surface * then rolled up and cleaned,

The innovation is based on the task of creating a window surface covering which has the advantages of curtains and roller blinds and, above all, for the attachment without additional mounting parts * for the operation without complicated and failure-prone mechanisms and, moreover, made of one material existsj whose production and acquisition is associated with extremely low costs. For this purpose, a roller blind-like window surface covering with the features listed in the preamble of the main claim is characterized by = paper and / or plastic as covering sheet material in commercial sizes, from which the supply roll required for the window surface in question can be separated
and through

An essential aspect is that they are appealing A wide variety of shapes and patterns can be provided in the production _s which do not lead to any significant price differences It is therefore also possible to provide for one and the same window area two supply rolls attached opposite each other, each for half the window area, or even just one window area covering that does not fully cover the window area, i.e. always leaving a part free the possibility of the supply roll set at any height of the window area and then unwind it accordingly to one or the other window edge, although the window covered with the window area covering should be the normal state * because otherwise the supply roll may be perceived as annoying.

As can easily be seen without further explanations, offer Such roller blind-like window coverings by no means only a replacement or a transitional solution for conventional curtains, drapes and roller blinds, they open up wide areas, so far certainly for reasons of cost Areas of application that have not yet been considered, e.g. for office or workshop rooms, where also not only the purchase, but also the care ^ i.e. in particular the cleaning the use of expensive textile materials or unadorned and heavily darkening roller blinds has not yet been allowed.

Especially with high windows where the supply roll is rolled up State is not or only poorly attainable without aids, the web material can be designed in multiple layers, of which at least one layer in its idle state the supply roll in

Preferred embodiments of the innovation can be made with strip inserts be provided in the Bdhnmaterial, which serve to the even ^ to support flat clamping. It can be made of metallic, organic or synthetic strips, for example Trade aluminum, wood or plastic, which, if they run across the direction of roll, are so brittle or have predetermined breaking points should be that they break under increased stress and show no permanent plastic deformation. It is different on the other hand, in the case of strip inserts running longitudinally to the direction of roll. These must be made of elastically deformable materials that, similar to a clock spring, have the tendency to get out of the to shape the deformed state back into a flat state.

Further preferred embodiments relate to the adhesives, with which the fastening or the fixing of the windows surface tension is brought about. Essential property of these adhesives is their different effect compared to the glass Window panes or the smooth surfaces of the window frames and the much rougher surface of the window covering material on the side facing away from the window area. In the rolled up state of the supply roll there is namely the free one End inside the roll and must not stick there. Adhesives that are either continuous or

openwork layer on the side facing the window surface of the covering sheet material are applied. These substances cause a sufficient definition of the free web end and / or the web material unwound from the supply roll on the window surface and / or a window frame spar. On the other hand, they are opposite to the rough surface of the sheet material, that of the window surface is turned away, practically ineffective, so that the supply roll can easily be unrolled and rolled up again and again. This should go through direct contact of the supply roll with the hands take place, at the same time the necessary pressure for the definition of the covering sheet material can be exercised on the window surface.

The situation is similar with a large number of suction cups outer support sheet on the side of the covering sheet material facing the window surface. Here, too, the suction cups take care of it a sufficient definition of the unrolled and resting on the window surface material, while it is opposite to the rougher Surface on the other side of the covering sheet material has no effect stay.

Albeit these adhesives in operation for securing the solid The end of the web is not sufficient, so they allow for the assembly to be attached, by additional means, e.g. adhesive tape or also Drawing board pins or the like, however, can then be securely attached without difficulty.

With the help of a Velcro tape known per se, the mushroom-shaped Has knobs in large numbers and can be attached in the area of the fixed web end of the supply roll, the supply roll easy to set when rolled up. The mushroom-grained ones Knobs of the Velcro tape then adhere to the rough surface of the web material when it is facing the window surface Side is attached at a slightly larger distance from the fixed end of the web, or on the side of the provided with the adhesive SahfidiatsriälS) if you put it briefly next to the fixed end of the track on the attached to the side of the sheet material facing away from the window slide. In a corresponding way, a sölehas Velcro strap can also be attached there

attached to the window surface or on the stile of the window frame, around the free web end of the supply roll in the unwound state set there.

As already mentioned above, self-adhesive climate films that are to be applied to glass surfaces are known. Another preferred embodiment of the innovation relates to a roller blind-like window surface covering that includes such a climate film, in which the tension sheet material is multilayered and at least one of the layers consists of a coated or colored reflective film and / or an insulating film. The insulation film unfolds its effectiveness due to the low thermal conductivity of non-moving air, so it can have a foam-like or fleece-like structure. A mutual cover with an air-impermeable film or layer, which can serve as on aer other hand, the required anyway for dao sheet material printed paper layer or the like, or the adhesive film, resulting in a sandwich-like Aufb. u, which leads to both a reduction in solar radiation and thermal insulation.

Regardless of the winding direction when the supply roll is rolled up, namely towards the window surface or away from the window surface, different sides of the web material of the individual roll layers are always adjacent in the supply roll in the rolled-up state. Since it is easier to roll up and down when turning away from the window surface, a supply roll rolled up in the winding direction towards the window surface is easier to fix in the rolled up state on the upper window edge between the spar protruding over the window surface and the window pane , one or the other type of winding can be selected as desired and in particular according to the frequency of winding and unwinding. Of course, it is also at the discretion of the user, for the end positions of the stationary or fixed end of the web as well as for the end positions of the movable, free end of the web or the intermediate positions of not completely unwound supply rolls ^ additional devices or holding means, e.g. adhesive tapes, possibly magnets or magnetic strips, smaller weights ,

-Located on the left, right or lower edge of the window and at any point on the glass pane b ^r . It is also possible for two supply rolls 6 to be located on opposite window edges, each of which is provided for one part, preferably one half of the window area.

Figures 2a and 2b show such a window with a window surface completely covering window surface covering 9, in which after unwinding the supply roll 6 according to Fig. La and Ib the free or movable tracks 8 at the opposite end of the track 7 at rest Window edge, here in the area of the lower window frame spar 3, is set. This is done using adhesives on the Side of the covering sheet material facing the window area, but which can be supported by additional adhesive, e.g. a Velcro strip 16 (see also Fig. 9). The adhesives on this side of the covering material can be continuous or interrupted be provided distributed over the entire surface and thus lead to a planar clamping. The one facing away in the window area Side of the window surface covering 9 is colored and designed in such a way that, for example, the impression of a curtain or a Curtain is created, which, with appropriate transparency of the web material, also when viewed from the outside, i.e. through the Glass pane 5 appears.

In the variants for fastening the stationary track end 7 of a supply roll 6 shown in FIGS. 3 to 7, there are the following differences: While according to FIG. 3 the stationary track end 7 is fastened to the glass pane 5, according to FIG. 2., 3 or 4 of the window frame or is like, Figures 5, 6 and 7 exclusively on one of the spars I ₄ Z> 3 or 4.

In the case of a simple design, the decorative paper or plastic film 12 can be dispensed with in this case, or in the case of a better design, a decorative fabric can be used instead of the paper or plastic film. Between the foils, layers or webs 11 and 12 there is an insulating layer 13, for example made of nonwoven material, foam, fiber material or the like. Stiff strip inlays 14 are embedded transversely to the direction of roll and support a planar stretching of the web material 9. These strip inserts 14 should consist of a brittle material that breaks when subjected to greater stress and does not experience any permanent deformation. The web material 9 can easily be smoothed again under these circumstances, and even if there is no longer any corresponding internal tension at such points, such damage is then only barely noticeable.

The strip inserts 14 can also have predetermined breaking points to cutting the covering material to a smaller width to support.
