Abstract
Corrugated transparent or semi-transparent structures, typically from Polycarbonate or Acrylic, are typically used for creating for example various transparent or semi-transparent walls or roofs for example in large buildings or for creating greenhouses for plants. However, especially for example during the summer, this can cause overheating of the greenhouse effect, so that too much heat is caught inside, which can have undesirable effects. The present invention shows a very cheap solution for automatically regulating the penetration of the Sun's rays through such structures during the day, so that for example at noon the Sun's penetration is automatically lowered. This is preferably achieved by using a sandwich in which two external transparent plates are connected by non-transparent or at least less transparent inner walls (also called bridges) and using appropriate orientations so that when the sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun.
Description
04/06/03 Yaron Mayer and Ai J.C. Baur 2,11 Background of the invention Field of the invention:
The present invention relates to the plastics industry, and more specifically to a system and method for producing corrugated semi-transparent structures which automatically change their transparency to the Sun's rays during the hours of the day, and the resulting structures.
Background Corrugated transparent or semi-transparent structures, typically from Polycarbonate or Acrylic, are typically used for creating for example various transparent or semi-transparent walls or roofs for example in large buildings or for creating greenhouses for plants. Polycarbonate has better impact resistance than Acrylic but is also more expensive and Iess transparent. For example in Russia and other Furopean countries such structures are used for greenhouses since they have the advantage of being stronger than nylon tents, so that for example in the winter they can resist better wind, snow or hail.
In fact this structure are typically even stronger than glass, and also they have better heat retaining abilities than glass. 'Typically these stn~ctures include materials that provide ~JV protection and they can last 10 or even 20 years in the Sun. Also, these structures have an advantage over glass in that they are more flexible and thus can be more easily fitted for example for round structures such as domes, and also they are easier to ship for this reason since such corrugated plates an be for example rolled up for shipment. I~owever, especially for example during the summer, this can cause overheating of the greenhouse effect, so that too much heat is caught inside, which can have undesirable effects. ~f course it is possible to use for example chemical materials that change their transparency according to the amount of light as is used for example in same optical glasses, or for example to change mechanically the amount of exposure to the Sun's rays for example by using various light sensors and/or by using temporal control, however these solutions are more expensive. The typical solution used in such greenhouses is covering them during the summer with a thin layer of Sun blocking material, such as for example white lime, which reduces the exposure to the Sun during the summer and is washed away by rain in the winter, but this is a messy and less aesthetic solution and creates extra work. It would be desirable to have a much cheaper solution f~r automatically regulating the amount of exposure to the Sun, that can be preferably mass-produced.
04/06/03 Yaron Mayer and A1 J.C. Baur 3/11 Summary of the invention The present invention shows a very cheap solution for automatically regulating the penetration of the Sun's rays through such structures during the day, so that for example at noon the Sun's penetration is automatically lowered. This is preferably achieved by using a sandwich in which two external transparent plates are connected by preferably non-transparent (or at least less transparent) inner bridges and preferably using appropriate orientations so that when the Sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun. This way automatically less heat is generated at mid-day inside the building or greenhouse or other structure that uses these corrugated structures in the roof and/or in the walls. This can have the further advantage that for example less energy might be needed for cooling the enclosure. To the best of our knowledge this has not been done before, so in the prior art these corrugated structures are either made from transparent or from non-transparent materials (for example for creating plastics storage cases, etc.).
Brief description of the drawings Fig. 1 shows an example of a normal Greenhouse built of a corrugated transparent plastic material (prior art).
Figs. 2a-a show a few examples of a side view of preferable corrugated structures based on preferably two transparent or semi-transparent plates separated by non-transparent or less transparent internal walls/bridges.
Important Clarification and ~lossary~
Throughout the patent when possible variations or solutions are mentioned, it is also possible to use combinations of these variations or of elements in them, and when combinations are used, it is also possible to use at least some elements in them separately or in other combinations.
These variations are preferably in different embodiments. In other words: certain features of the invention, which are described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are described in the context of a single embodiment, may also be provided separately or in any suitable Sub-combination. rill these drawings are just exemplary diagrams. They should not be interpreted as literal positioning, shapes, angles, or sizes of the various elements.
04/06/03 Yaron Mayer and Al J.C. Baur 4/11 Detailed description of the preferred embodiments All of the descriptions in this and other sections are intended to be illustrative examples and not limiting.
Referring to Fig. 1 we show an example of a normal Greenhouse built of a corrugated transparent plastic material, available from htta:/Iwww.sunshine~;reenhouse.com/ (prior art). As can be seen the structure is more or less similarly transparent in all directions. Although they claim that the angles of the roof at 45 degrees themselves help by reflection to let more light in from the lower winter Sun and. less light in from the higher summer sun, the differences that can be achieved by the present invention are much bigger. Also their solution does not use variable light penetration through the vertical walls.
Referring to Figs. 2a-e, we show a few examples of a side view of preferable corrugated structures based on preferably two (or more) transparent or semi-transparent plates (la & Ib) separated by non-transparent or less transparent internal wallslbridges (2). Preferably this structure is produced by extrusion by using for the internal bridges (2) that separate between the plates (la &
lb) production slits that are fed by a separate non-transparent or less transparent material than the material fed for the external plates ( 1 a & 1 b). Of course this is just an example and the internal bridges can have also other shapes and/or angles and/or sizes, but internal bridges (2) at 90 degrees to the plates (1a &
lb), as shown in Fig. 2a, can be very convenient for using as vertical walls (4) in the structure shown in Fig. 2b. By using such a structure as the vertical walls (4) of a greenhouse for example, so that the two (or more) plates (la &
lb) are vertical and the internal bridges (2) become horizontal, when the Sun is low (when rising or setting) (3a) the light from the Sun can enter directly, and when the Sun is higher in the sky at noon (3b) the internal bridges (2) block the direct light from the Sun. If the roof (5) is build from a similar structure then preferably the internal bridges within it are instead tilted.
Preferably the direction and angles of this tilt of the internal bridges and/or the direction of the entire preferably elongated greenhouse take into account also the orientation relative to where the Sun is rising or setting in order to achieve the desired effects. Also, in the winter for example the Sun's orientation in the sky is lower than in the summer, so this is preferably also taken into consideration in the orientations and/or angles used, so that preferably also automatically more sunlight enters the structure in the winter than in the summer. Of course this is just an example and the inner bridges (2) between the vertical plates (la & lb) can be also for example in some diagonal orientation - depending on the most desired angles of Sun penetration, and not necessarily in the horizontal orientation that is shown. Another possible 04106/03 Yaron Mayer and A.1 J.C. Baur 5/11 variation, shown in Fig. 2c, is that the roof (5) is made for example from a corrugated structure with internal bridges that are also transparent and for example the bottom plate (Sb) is transparent and the top plate (Sa) is for example non-transparent or semi-transparent. Another possible variation, shown in Fig. 2d, is that the roof is constructed 'from two tilted carrugated structures (6 & 7) which also each have internal tilted bridges in them, so that their internal bridges become preferably horizontal (or at another convenient angle) in the final structure, thus working similarly to the internal bridges of the vertical walls (4) of the for example greenhouse. This or similar designs also have the advantage that snows for example can slide down easily without causing burden on the roof. Of course these are just a few examples and many various other variations are also possible, and also the use for a greenhouse is also just an example. For example various combinations of different angles of the internal bridges {2) and different transparency levels of the internal bridges (2) or of the external plates can be used. Also, although typically such corrugated structures are made of Polycarbonate or Acrylic, other materials with the desired qualities or combinations of different materials can also be used. As can be seen in Fig. 2e, if the angle of the Sun is higher than R, no direct light penetrates directly. 'When the corrugated structure is used as a vertical wall, the height (H) between the internal bridges (2) and the distance between the two plates (D) create the radius that makes the Sun stop penetrating. Another possible variation is for example to keep the inner bridges (2) between the rivo (or more) plates ( 1 a & 1 b) transparent or semitransparent, but preferably cover them with a light-reflective material and use them in a convenient angle, so that they reflect back more or less Sun depending on the angle from which the Sun light hits them. The above solutions have the advantage that the desired angles can be chosen independently of the orientation of the external plates (la &lb). Of course the greenhouse or other enclosure can have for example only the roof or only one or more of the walls made of the described corrugated structures. Of course the plates {la & lb) are not necessarily straight and may be instead for example wavy or with some other curves, but straight plates are usually more convenient. Of course various combinations of the above and other variations can also be used.
While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications, expansions and other applications of the invention may be made which are included within the scope of the present invention, as would be obvious to those skilled in the art.

c. The roof is constructed from two tilted corrugated structures which also each have internal tilted bridges in them, so that in the final structure said internal bridges become horizontal or at another convenient angle.
6. The system of any of the above claims wherein the inner bridges between the plates are transparent or semitransparent, but they reflect
7/11 back more or less Sun depending on the angle from which the Sun light hits them 7. The system of any of the above claims wherein the corrugated structures are made of at least one of Polycarbonate and Acrylic.
8. A method for using corrugated structures which automatically change their transparency to the Sun's rays during the hours of the day, comprising the steps of:
a. Using at least two transparent or semi-transparent plates.
b. Using non-transparent or less transparent inner bridges that connect between said plates.
a. Using at least two transparent or semi-transparent plates.
b. Using non-transparent or less transparent inner bridges that connect between said plates.
9. The method of claim 8 wherein appropriate orientations are used so that at least one of the following features exist:
a. When the Sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun.
b. In the winter, since the Sun is lower in the sky, the Sun's rays can enter more directly, and in the Summer, since the Sun is higher in the sky, the rays are more blocked from entering directly.
a. When the Sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun.
b. In the winter, since the Sun is lower in the sky, the Sun's rays can enter more directly, and in the Summer, since the Sun is higher in the sky, the rays are more blocked from entering directly.
10. The method of any of the above claims wherein said corrugated structures are used as at least one of at least one wall and the roof of at least one of a building, a greenhouse, and other types of enclosures.
11. The method of claim 10 wherein said corrugated structures are used as at least one vertical wall so that the plates are vertical and the internal bridges are horizontal or at some other convenient angle.
12. The method of claim 10 wherein said corrugated structures are used in the roof and at least on of the following features exist:
a. Said inner bridges between the plates are tilted so that the direction and angles of this tilt of the internal bridges and/or the direction of the entire greenhouse or building or enclosure take into account also the orientation relative to where the Sun is rising or setting in order to achieve the desired effects.
b. The roof is made from a corrugated structure with internal bridges that are also transparent and the bottom plate is transparent and the top plate non-transparent or semi-transparent.
