Description

  The present invention attaches to the ceiling of a structure and partially irradiates the illumination light to the space below the ceiling, such as the illumination light of a lighting device installed on the indoor ceiling or sunlight that passes through the ceiling in a structure without a roof. The present invention relates to a light-shielding device used for blocking or transmitting light and a structure of a simple awning building provided with the same.

A pergola is installed in the park where people gather, on the terrace of the building, on the roof, and in the garden to create a space for sunshade.
Pergola is formed by arranging shelves side by side on the ceiling of a frame made of wood or steel, allowing the sun to pass through the gaps between the shelves, and further by planting the shelves on the ceiling. The space below is a sunshade, but the ceiling shelves are fixed, so the amount of light transmitted through the sun cannot be adjusted, and the pergola is uniformly strong during the daytime in the summer when the sun is at a high altitude. It is not possible to adjust the amount of sunlight according to the season or sunshine time, such as when it is exposed to sunlight.

  As an outdoor structure to solve such problems, guide means extending in the direction in which shelves are arranged on both sides of the ceiling of the pergola are attached, and curtain-like cloth curtains are installed on both guide means. When the sunlight is weak, fold the cloth curtain around the end of the guide means, and when the sunlight is strong, the cloth curtain is projected below the ceiling along the guide means to adjust the sunlight inside the pergola. A configuration that adjusts with a curtain is known (see, for example, Patent Documents 1 and 2).

JP 2002-54312 A JP 2003-41653 A

  A fabric curtain that can be opened and closed inside the pergola to adjust the sunlight can block strong sunlight by extending the fabric curtain along the ceiling, but the fabric curtain that projects inside the pergola is wind Therefore, even if the sunlight is strong, the cloth curtain cannot be extended when the wind is strong, and when the wind becomes strong with the cloth curtain extended, it must be folded each time. When the pergola is installed adjacent to a residential house, there is no hindrance to opening and closing the cloth curtain as described above, but an openable curtain is installed on the pergola installed in a public facility such as a park. It is not realistic to open and close the curtain according to the strength of the wind and the strength of the wind.

  In addition, in the structure with a cloth curtain that can be opened and closed freely, the entire interior of the pergola can be shaded by overhanging the cloth curtain. It is not possible to adjust the change of the internal sunshine to be a gradient.

  In view of such a problem of the prior art, the present invention can adjust the intensity of sunlight inside the structure as appropriate in a light-shielding device installed on the ceiling of the structure, hardly affected by wind. The challenge is to do so. Moreover, this invention makes it a subject to comprise the simple shading building provided with the said light-shielding device and suitable for installing in outdoor public facilities, such as a rooftop and a park.

In order to solve the above problems, the present invention is a light shielding device installed on a ceiling of a structure, wherein a plurality of light shielding curtain units configured by passing a plurality of light shielding sheets through linear members face the ceiling. The structure has a configuration in which the structure is arranged in parallel with a space between adjacent light shielding curtain units.
In the present invention, the ceiling refers to the upper surface inside the structure, and when the structure is a roofed building, the upper surface of the room covered with the roof and attached with the lighting device, the pergola installed outdoors In the case of an awning building without a roof, the surface above the open building through which sunlight passes.

  According to this, light that illuminates the lower part of the ceiling, that is, with a roof, is provided by arranging a plurality of warm-shaped light-shielding curtain units that are suspended by hanging a plurality of light-shielding sheets on linear members below the ceiling. In the buildings of, the lighting light of the lighting device attached to the ceiling, and in the building for sunshades without a roof, the sunlight transmitted through the open ceiling is appropriately blocked by the light shielding sheet of each light shielding curtain unit, and the lighting in the space below the ceiling And the amount of sunlight can be adjusted. In this case, by appropriately setting the number of light-shielding curtain units arranged facing the ceiling, the arrangement interval or arrangement density between the units, the amount of lighting and sunlight in the space below the ceiling can be adjusted, and It is possible to increase or decrease the amount of lighting and sunlight in a predetermined part. The light-shielding curtain unit is not formed by hooking a long sheet of light-shielding sheet on the linear member, but is divided into a plurality of light-shielding sheets and hangs down on the linear member. Even if it is received, the wind pressure applied to the light-shielding curtain unit is dispersed by shaking each light-shielding sheet independently. Therefore, even if it is attached to a structure installed outdoors, the influence of the wind pressure is extremely small.

  In the ceiling light-shielding device having the above-described configuration, guide rails each including a plurality of slidable engagement bodies are arranged in parallel on the inner surfaces facing each other across the ceiling of the structure. Preferably, both ends of the light shielding curtain unit are connected to each other, and a plurality of light shielding curtain units are installed between the guide rails.

According to this, each light shielding curtain unit installed between the guide rails is configured to be slidable along the guide rail integrally with the engaging body housed inside the guide rail. It is possible to move each light shielding curtain unit individually and adjust the arrangement interval between the light shielding curtain units and appropriately. For example, when installing in a sunshade building, the shade position that can be placed under the ceiling by evenly or unevenly arranging the light shielding curtain units according to the season, sunshine time, sun height, etc. It is possible to adjust the amount of sunlight.
In addition, a position fixing member such as a lock nut is provided at the connecting portion between the light shielding curtain unit and the engaging body, and the position fixing member is determined after the light shielding curtain unit is moved along the guide rail and the installation position is determined. It is preferable that the engagement body is fixed to the guide rail and that the light-shielding curtain unit is slidable by releasing the fixing by the position fixing member.

In the ceiling light-shielding device having the above-described configuration, the linear member constituting the light-shielding curtain unit may be a synthetic resin string material, a flexible metal wire or rod, or the like.
The light shielding sheet is preferably formed using a synthetic resin cloth material. As the material of the light shielding sheet, it is preferable to use a light cloth material having a light shielding property, for example, a cloth material having a UV cut function in which a polyester cloth is coated with a vinyl chloride resin. A tent fabric excellent in weather resistance may be used.
For example, the light-shielding sheet is formed by cutting a cloth material into a rectangular shape, folding the cloth material in half in the lateral direction, forming a hole through which the linear member is inserted in the upper side, and folding the left and right sides to sew or It can be formed in a rectangular shape with dimensions of about 200 mm in length and 600 mm in width, for example, by securing the strength by heat welding or bonding and stitching the bottom side together or by heat welding.
A light-shielding curtain unit is formed by passing a plurality of light-shielding sheets through the linear member. In this case, the linear member can obtain a predetermined light-shielding effect without moving the light-shielding sheet along the linear member. It is preferable that a plurality of light-shielding sheets be provided in parallel between the both end portions without any gaps between adjacent light-shielding sheets.
Note that the formation dimensions of the plurality of light-shielding sheets suspended from the linear member need not all be the same. For example, multiple types of light-shielding sheets with different vertical and horizontal dimensions are prepared, and light-shielding curtain units are configured by passing light-shielding sheets with different dimensions through linear members, or light-shielding sheets with different dimensions are arranged for each light-shielding curtain unit. Or you may.
