Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plate screen installed on the indoor side of a window for shading or blinding a window in which the window glass is fitted.

[0002]

[Prior art]

 Conventionally, curtains, blinds, roll screens, etc. have been installed on the indoor side of windows for the purpose of shading, shielding heat, blindfolding for privacy protection, etc. for windows fitted with transparent window glass. It is common to open and close.

In a conventional general curtain, blind, roll screen, or the like, one end or one side of the curtain surface is fixed, and light shielding or the like is adjusted by moving the other end or the other side. For example, in the case of a one-sided curtain, one of the left and right side ends is fixed, and the other side end is moved to the left and right for adjustment. Also, for blinds and roll screens, the upper end is usually fixed and adjusted by raising or lowering the lower end.

[0004]

[Problems to be solved by the invention]

 However, it has been difficult to freely adjust the position to an optimum position according to a change in the angle of sunlight with a fixed end, such as a conventional curtain or blind.

[0005] For example, regarding the shielding of summer solar radiation, when there are concave and convex surfaces such as curtains and blinds, the solar radiation heat incident on these concave and convex surfaces is reflected toward the indoor side, and radiant heat having a long wavelength is used. As a result, it is irregularly reflected, and causes an increase in the room temperature.

[0006] Furthermore, in the related art, when completely shielded, the concealing property of the entire window is enhanced, and there is a place where dust and the like accumulate, which may cause a problem in hygiene.

[0007] In view of the above problems, the present invention can be freely adjusted to an optimum position according to a change in the angle of sunlight, and does not reflect solar radiation heat indoors, has no concealment property, and is open. It is an object of the present invention to provide a window screen realizing a feeling.

[Embodiment of the invention]

 FIG. 1 is a perspective view of an embodiment of a light-shielding plate screen 10 according to the present invention. The light shielding plate screen 10 is installed, for example, on the indoor side of a window frame in which a transparent window glass is fitted. The pair of guide rails 14 are a pair of hollow tube members installed in parallel with each other, and have slits 15 in the longitudinal direction on opposing surfaces. The left and right side ends of the light shielding plate 12 are inserted into the slits 15 and can move up and down along the guide rails 14 as shown by arrows. That is, the length of the light shielding plate 12 in the vertical direction is shorter than the length of the slit 15 of the guide rail 14. For example, the length of the light-shielding plate 12 in the vertical direction is set to be about 1/2 to 1/3 of the height of the window, and a part of the outside scene is always visible from a portion where the light-shielding plate 12 is not provided. It is preferable to reduce the concealment of the window.

The vertical movement of the light-shielding plate 12 can be easily performed by pushing and pulling the upper or lower side of the light-shielding plate 12 by hand. In order to smoothly perform this vertical movement, a light plate material is used as the light shielding plate 12.

The light-shielding plate 12 is not transparent because it aims at light-shielding, heat-shielding or blindfolding, but is desirably a translucent plate material. A lightweight, tough and light-shielding plastic material, for example, a material such as a hollow-layer polycarbonate resin having a thickness of about 5 m / m to 10 m / m is suitable. Preferably, when a light-transmitting thin film, for example, a film on which a pattern such as a shoji screen is printed, is stuck to the indoor facing surface of the light shielding plate 12, the light is adjusted and softened. The atmosphere is realized. More preferably, a film material having a radiation heat reflection effect, for example, a film on which aluminum is vapor-deposited is laminated on the surface of the light-shielding plate 12 facing the window, so that the solar radiation heat is reflected to the outside to enter the room. Solar radiation heat can be largely prevented.

As shown in FIG. 1, the light shielding plate screen of the present invention is a method in which only a part of the window is always shielded, and the light shielding plate can be moved up and down according to the movement of the sun. It is characterized by the openness of the windows and the constant brightness. Furthermore, in terms of privacy preservation, if it is sufficient to cover the necessary line of sight, it is not necessary to cover the entire window, and the situation in which the entire outside view cannot be seen from the indoor side can be avoided.

In the embodiment of FIG. 1, only one light-shielding plate is provided on a pair of guide rails. However, as another embodiment, a plurality of separated light-shielding plates are provided, each of which is moved up and down. Is also good. For example, one sheet can be arranged on the upper side and one sheet on the lower side, and the middle can be opened. As still another embodiment, the light shielding plate screens 10 as shown in FIG. 1 may be provided in a double or triple manner, and the light shielding plates provided on each pair of guide rails may be individually moved up and down. In this case, the brightness, the area and the position to be covered can be adjusted more finely.

FIG. 2 is a partially cutaway view of one guide rail 14 and its vicinity. A braking portion 18 is provided at a side end of the light shielding plate 12 inserted into the slit 15. In this case, the braking portion 18 is formed by bending a flexible band material such as plastic and fixing both ends thereof near the side ends of the light shielding plate 12. The curved portion of the strip is in contact with the hollow inner surface of the guide rail 14 and is in an elastically biased state. As described above, since the braking portion 18 elastically presses the hollow inner surface of the guide rail 14, when no load is applied to the light shielding plate 12 (for example, the light is not pushed or pulled for vertical movement). 2), the light shielding plate 12 can be kept stationary by frictional engagement between the braking portion 18 and the hollow inner surface. It is preferable that at least one braking portion 18 is provided at each of the left and right side edges of the light shielding plate 12, but depending on the length and weight of the light shielding plate 12 and the strength of the elastic force of the braking portion, What is necessary is just to set the installation number of a braking part suitably.

When a force that pushes or pulls the light-shielding plate 12 to move the light-shielding plate 12 up and down is applied, the braking unit 18 can slide along the hollow inner surface. The frictional engagement between the braking portion 18 and the hollow inner surface has such a strength that the sliding can be performed smoothly and lightly.

More preferably, a guide portion 16 is attached to a side end of the light shielding plate 12 in order to ensure a smooth vertical movement of the light shielding plate 12. By making the shape of the guide portion 16 into a shape that fits into the hollow of the guide rail 14, it is ensured that the light shielding plate 12 moves smoothly up and down along the guide rail 14 without rattling. The number of guides 16 to be attached depends on the shape of the guides 16 and the length of the light-shielding plate 12, and is arbitrary. For example, it is preferable to attach one guide to each of the left and right side ends. .

FIG. 3 is a view showing another embodiment of the braking unit 18 and the guide unit 16 provided at the side end of the light shielding plate 12. FIG. 3A is a partially cutaway front view, and FIG. 3B is a side view. The braking portion 18 is a band material such as plastic, the base end of which is fixed to the guide portion 16, and the free end of which is elastically urged by a coil spring 19. Thereby, it is pressed against the hollow inner surface of the guide rail. The coil spring 19 is mounted in a cutout recess at the side end of the light shielding plate 12. Thus, the braking part 18 and the guide part 16 may be provided integrally.

FIG. 4 is a view showing still another embodiment of the braking unit 18 and the guide unit 16 provided at the side end of the light shielding plate 12. 4 (A) is a front view, FIG. 4 (B) is a side view, and FIG. 4 (C) is a sectional view taken along line XX of FIG. 4 (A). In this embodiment, the braking portion 18 is formed in a substantially spherical or elliptical shape using an elastic material such as a rubber material, and is attached to a side end of the light shielding plate 12 with an adhesive or the like. If the size of the braking portion 18 is made slightly larger than the hollow of the guide rail, the braking portion 18 can be elastically urged against the inner surface of the hollow by inserting it into the hollow space of the guide rail. And

FIG. 5 is a view showing some arrangement examples of the braking portions 18 provided on the side ends of the light shielding plate 12, and is a view of the guide rail 14 and the light shielding plate 12 as viewed from above. FIG. 5A shows an example in which the braking portions 18 are provided on both surfaces near the side end of the light shielding plate 12 and are elastically urged against the inner surfaces 14a and 14b. FIG. 5B shows an example in which the braking portion 18 is provided on the side end surface of the light shielding plate 12 and is elastically urged against the hollow inner surface 14c. FIG. 5C shows an example in which the braking portion 18 is provided on both sides and side end surfaces near the side end of the light shielding plate 12, and is elastically urged against the hollow inner surfaces 14a, 14b, and 14c. Various arrangements other than these examples are possible.
