Description

Window blinds and protection Against the sun

The present invention relates to a blind with vertical slats.

This type of window decorations applies frequently in offices where computers are used. The Computer screens can be read properly only if the incident light from outside is sufficiently dimmed. In the today, the window decorations known in themselves they can dim the light sufficiently to make readable so appropriate a screen arranged in a workplace. Do not However, a drawback of window type decorations known is that the use of them has been shown little nice. Tests performed have shown that people that are in a space in which the windows are equipped of the known decorations, after the course of a certain time, they start not feeling well, which can lead to mental and physical tensions.

The objective of the present invention is to publicize a solution to the problem mentioned above. With this objective, the blind of vertical slats according to the present invention is characterized because the window decoration when it is brought to use conditions, it comprises a first face that extends in horizontal direction substantially at least to the full width of the window decoration and a second face which extends horizontally from the decoration of the window, so that the first and second faces are formed by vertical slats, while in each of these slats is fulfilled which transmits at least substantially no light in a first part of the reference or relevant plan, being part said first zone of the first face, and partially transmits light for a second zone of the relevant lama, said second forming zone part of the second face so that the first face does not transmits substantially light, damping the second side of the light incident in such a way that a person who is present in a workplace in an internal space equipped with the decoration of Windows can look outside through the second side, the first face being located above the second.

Since a person can still look at certain form across the second face and can distinguish as At least the contours of the outside, it no longer feels oppressed. Also when a person is during a period of longer time in a space with a decoration of window according to the invention, it turns out that the tensions before Mentioned physical and mental type does not take place.

Also, the screens remain readable appropriately despite the transmission of a certain amount of light on the second side. However, this is offset by the fact that the first face does not transmit substantially light, of way that the total light transmission of the window decoration is low enough to allow the proper reading of the screens

It is preferably fulfilled that the second face is extends at least substantially the entire width of the window decoration. The latter will be the case in particular when the window decoration itself has a width approximately the same as the window or door in front of the which is the decoration of the window.

In addition, it is particularly true that the first and Second faces are adjacent to each other.

Likewise, it will be generally fulfilled that the second face extends down to a lower area of the window decoration. However, this is not indispensable. Likewise, it is generally fulfilled that the first face extends until the top of the window decoration. However, this It is not indispensable either, because at the top of the Window decoration can be found in addition to a face whose characteristics depart from those of the first face.

In particular, it is true that the first and second faces have a rectangular shape. (Horizontal or vertical).

The invention will be explained below. additionally referring to the attached drawings, in the which:

Figure 1 shows a blind with slats horizontal and a folded blind when it is mounted on a window of an interior space where a place of job;

Figure 2a is an elevation view of the louver blind of figure 1;

Figure 2b is a side elevational view of the folded shutter of figure 1;

Figure 3 shows a first embodiment of a blind with vertical slats according to the invention; Y

Figure 4 shows a second embodiment of a blind with vertical slats according to the invention. The blinds with horizontal slats shown in figures 1, 2a and 2b does not form part of the invention but represents a prior art related useful to understand the invention.

In figure 1, numeral (1) indicates a decoration / sun protection for a window, in the form of a blind with horizontal slats. The louver blind (1) is mounted on the wall (2) of an internal space (4) containing a Workplace (6) with an image screen (8).

In this example, a blind is used with horizontal slats, that is, the blind with horizontal slats is is in a stretched or expanded situation. Figure 2a is a side elevation view of the extended blind.

The louver blind includes slats horizontal (10), coupled in a known manner to a box upper horizontal, also of known type. Located in the box upper (12) is a mechanism to raise and fold the Window decoration by means of a lifting rope (18). A series of these slats (10.1) of a first type form a face whose width is indicated by the arrow (B) in the drawing and whose Height is indicated by the arrow (I) in the drawing. In addition, a series of slats (10.2) of a second type form a second face whose width is also indicated by the arrow (B) in the drawing and whose height has been indicated by arrow II in the drawing.

In this example, the slats (10.1) of the first type They have been designed so that at least they do not transmit substantially any light. In addition, the slats (10.2) of the second type are of such a design that they transmit the incident light from the exterior dimmed. For this purpose, the lamas (10.2) of the second type are perforated in a known manner and each of They comprise a large number of small openings.

As a result, in the apparatus shown in Figure 1, the window decoration, when taken to use situation, it comprises a first face (B, I) that is extends in horizontal direction at least substantially to all the width, and in this example even the entire width of window decoration, and window decoration in this state comprises a second face (B, II) that extends in horizontal direction of window decoration, no substantially transmitting any light on the first face, damping the second face the incident light so that the person present in the internal space in your workplace can still observe the outside through the second face, being located the first face above the second.

In this example, it is also applicable that the second face (B, II) extends at least substantially to the entire width of the window decoration and in this example even to the entire width of it. Also, in this case, it is true that the first and second faces are adjacent between yes. In addition, the second face extends down to the part bottom (14) of the window decoration. In turn, the first face extends upward to an upper part (16) of the window decoration. In this example, it is also true that the first face (B, I) is taller than the second face (B, II).

The slats (10.1) of the first type may be, by example, aluminum, plastic or a wooden design. I also know complies that the slats of the second type (10.2) may be Constructed of the same materials. It is also possible that slats of the second type (10.2) are made of plastic transparent, in which case perforations are not necessary.

In the situation shown in Figure 1, a person present in the workplace (6) who wishes to read the screen (8), will be able to do it properly. Due to the combination of the first face, which does not transmit light, with the second face that really transmits a part of the light from the outside, the total amount of incident light is sufficiently damped to make the screen (8) continue to be appropriately readable. At the same time, a person present in the workplace (6) you can still look outside through of the second face (B, II) and distinguish at least the contours of the outside. In this example, a series is vaguely visible of trees (20).

If the window decoration is designed as fold window, which contains a sheet material folded into a single piece, its appearance will be comparable to figure 1. This Window decoration comprises a top box (12) and a lower crossbar (21), while between the upper box (12) and the lower cross member (21), under conditions of extended use, exclusively a folded sheet material is located in only one piece. However, this material, folded into one piece, can be constructed from different sheets of material. The first face is then constituted by a material folded laminar (22) that substantially does not transmit any light (no transparent or semi-transparent; see figure 2b). The second face It is formed by a folded sheet material (24) that transmits by at least partially the incident light. The first sheet material (22) may consist, for example, of a fabric that has a Aluminum coating applied to it by vaporization. The same is true for the second folded sheet material (24), in the that, however, a perforation has been arranged in the material laminate so that the person who is in the place of Work can look outside to some extent. The second folded sheet material may also consist of a fabric transparent. Said first and second sheet materials are directly interconnected and constitute the sheet material folded in one piece; in other words: no crossbar intermediate between the first and second sheet materials (22), (24) and others. The connection may consist of a layer of an adhesive (25). It is evident that the blind with horizontal slats of the Figures 1, 2a and 2b is not part of the invention but is useful for your understanding

Figure 3 shows a first embodiment of a window decoration according to the invention. They have designated the parts corresponding to those in the figures above with the same reference numerals. In the decoration window according to figure 3, it can be seen that it is designed in shape of blinds with vertical slats. The first face (B, I) and the second face (B, II) are constituted by the same slats vertical (30).

In addition, it is true in each of these lamas that they substantially do not transmit any light in a first part (32) of the slats located on the first face (B, I) and that these slats they comprise a second part (34) that partially transmits the light, said second zone or part of the second face being part (B, II). The above can be achieved, for example, by the manufacture of the slats (30) based on aluminum and / or plastic (PVC), while only the inner sides or areas of the lamas, that is, part (34) of each of the lamas, is endowed of perforations. Other variants are slats manufactured from colored, transparent plastic that partially transmits light incident, although it is also fulfilled that the first part (32) of each of the slats is equipped with a coating that does not transmits substantially light. Accordingly, the effect is again that the first face (B, I) extends in the direction horizontal to the entire width of the window decoration and substantially it does not transmit any light, while the second face (B, II) extends similarly in the horizontal direction, in this case even the entire width of the decoration of the window, dimming the second face the incident light in such a way that the person who is in the workplace in space interior can still observe the exterior through the second face, the first face being located above the second.

Figure 4 shows a second embodiment of a window decoration according to the invention that corresponds as minimum substantially to the window decoration of figure 3. In this case, however, the slats are of a longer design, forming a third face (B, III). This third face (B, III) can have, for example, the same characteristics as the second face (B, II). Each of the slats (30) then comprises a third zone (34) that has the same characteristics as the zone or part (32) of the corresponding plank. However, it is also possible that the third side (B, III) has the same characteristics as the first face (B, I). Each of the slats (30) then comprises a third part or zone (36) that has the same characteristics than part (22) of the corresponding plank. The face (B, III) can be located, for example, below the window threshold and not it is essential that it be a partial transmitter of light to create the possibility to look through it. Also, if the window extends to the ground (40), the third face (B, III) can be designed to not transmit light. Certainly a person present in the workplace you can always look out at a certain measured through the second face (B, II). Of course, the third face (B, III) may also have characteristics related to the light transmission that differ from those of the first and second faces (B, I) and (B, II).

In the above described, the first face and The second side are both rectangular. However, it you can also think, for example, that the second face has a shape other than rectangular. It is also possible that the blind with vertical slats (figures 3, 4) be enlarged on one side or in both with additional slats that are completely or partially transparent and / or non-transparent. Lamas can be suspended, for example, beyond a window in front of a wall and can have, for example, exclusively function decorative It is also possible that two or more louver blinds verticals according to the invention are mounted on a guide or horizontal box (12), for example for suspension in front of two or more windows In front of an intermediate space between the windows additional slats can then be suspended from a guide or box horizontal (12). These additional slats can be complete or partially transparent and / or non-transparent, also forming additional window decorations. These variants are due understand that they are included within the scope of the invention such as defined in the following claims.
