Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a natural light blocking device for a retractable roof that can arbitrarily take in or block natural light from the roof in a building employing a retractable roof. It is.

<<Prior Art>> As is well known, structures for athletic events such as baseball stadiums and track and field stadiums do not have roofs.

This is intended to allow athletic competitions to be held in as natural a environment as possible, but if it rains or it rains during a competition, the competition must be suspended or canceled.

Therefore, an all-weather stadium has been proposed.
Retractable roofs that can be slid to open the top are attracting attention.

This allows the roof to be moved to the roof opening during rainy days,
Additionally, the roof allows for natural light to be used for competitions.

《Problem that the invention aims to solve》 Description: Buildings with conventional retractable roofs can be used in rainy days, and also provide natural light and natural ventilation in sunny weather. In order to further expand the purposes of use of such buildings, there is a need to arbitrarily block natural light and enable illumination with artificial light. For example, the effectiveness of spot lights is essential for figure skating, concerts, etc., and there is a desire for a building with a retractable roof that can be used for such events.

This invention was developed in view of the above circumstances, and its purpose is to provide a natural light blocking curtain that can be opened and closed on the back side of a retractable roof that allows natural light to pass through, allowing artificial light to be used by blocking natural light at will. To provide a natural light blocking device for a retractable roof.

<Means for Solving the Problems> In order to achieve the above object, the natural light blocking curtain device for a retractable roof according to the present invention is a retractable roof that has an opening at the top and can arbitrarily close this opening. A translucent material that allows light to pass through is used for the roof member, and a blackout curtain made of an opaque material that can be expanded and contracted in the direction parallel to the roof member is arranged in small sections in predetermined areas at the bottom. It is to be established.

<<Operation>> Regardless of whether it is a sunny day or a rainy day, when artificial lighting is used, the opening in the top of the building is closed with a retractable roof. The blackout curtains are then extended to block the natural light that enters the building from the roof.

<<Embodiment>> Hereinafter, a natural light blocking device for a retractable roof according to the present invention will be described with reference to the drawings.

In Part 1, we will give an overview of the situation. In this example, the retractable roof has a multi-layered structure in which an upper movable roof 1 and a lower movable roof 2 are stacked, and the upper movable roof 1 extends over the lower movable roof 2 in the front and back direction. Move by sliding. In addition, the lower movable roof 2 is placed with the upper movable roof 1 on it,
It moves in the front-back direction on the roof support beam 3.

On the inside of the frame body 4 that constitutes the outer shell of each movable roof 1, 2, horizontal beams 5 are provided in parallel to obtain subdivisions 6, and the horizontal beams 5 also serve as structural members for reinforcing the frame body 4. .

A blackout curtain 7 for blocking natural light that has passed through the movable roofs 1 and 2 is housed within the subdivision 6 so as to be expandable and retractable laterally.

FIG. 2 is a schematic end face of the lower movable roof 2 viewed from the side, with the blackout curtain 7 being retracted. The springs 8 are sewn onto these non-transparent materials so as to have a flat shape.

The spring 8 is made of elastic-plastic wire rods arranged in a triangular shape.
When the non-light-transmitting material is shrunk, these will be arranged laterally in the subsection 6.

That is, the blackout curtain 7 is housed in the small section 6, in which a diamond shape in which the bases of adjacent triangular springs 8 are in plane contact with each other is sewn continuously in the lateral direction of an opaque material.

This will be shown in more detail in FIGS. 3 and 4, and the expansion and contraction function of the blackout curtain 7 will be explained. A guide rail 9 is provided near the upper side of the crossbar 5, and a blackout curtain 7 is attached to a plurality of upper hangers 10 that slide within the guide rail 9. The upper hanger 10 is a rectangular plate made of lightweight metal or ultra-high tensile strength resin, and is slidably installed between the guide rails 9 of the adjacent horizontal bars 5-5. The blackout curtain 7 is suspended from an upper hanging base 10.

A ring 12 through which a slide wire 11 for extending and contracting the blackout curtain 7 is passed is fixed on the upper surface of the upper hanging base 10. By pulling or returning the slide wire 11, the blackout curtain 7 is expanded and contracted as shown in FIGS. 4a and 4b. For this purpose, the tip of the slide wire 11 is as shown in FIG.
It is tightly attached to the upper surface of the upper hanger 10' located at one end of the subsection 6 with a fixing metal fitting 13, and the base end passes through the ring 12 on the other upper hanger 10 and is attached to a take-up reel (not shown). The blackout curtain 7 is expanded and contracted by rotating this reel.

FIG. 6 shows a schematic configuration of the guide rail 9 and the upper hanger 10, and the blackout curtain 7 in the figure has sinusoidal springs 8 and straight springs 8 connecting the tops of the blackout curtain 7. are suspended from the upper suspension base 10 at appropriate intervals, and guide rails 9 are installed at both ends of the upper suspension base 10.
A support shaft 15 of a moving wheel 14 received therein is connected.

In this way, the upper suspension base 10 is moved by the wheels 14 in the guiding direction of the guide rail 9. Further, the midway portion of the upper suspension base 10 is slidably suspended from a roof structural material by a hanging metal fitting 16 to prevent distortion thereof.

The translucent roof member 17 of the movable roofs 1 and 2 is a blackout curtain 7
It forms a structure that covers the upper part of.

As described above, the blackout curtain 7 is formed by the translucent roof member 17.
By opening and closing the back surface of each movable roof 1, 2 in a direction parallel to the roof member 17, transmitted light from the roof member 17 can be arbitrarily blocked.

<<Effects>> As described in detail above, according to the natural light blocking curtain device for a retractable roof according to the present invention, a blackout curtain made of an opaque material is placed on the back side of a movable roof made of a transparent material that transmits light well. Since it is extendable and retractable, natural light can be blocked at will and the indoor space can be switched to artificial lighting. As a result, the building can now be used for multiple purposes such as business, music concerts, and exhibitions. In addition, this blackout curtain is divided into small sections for each predetermined area, so
It is also possible to select where natural light enters and where it is blocked.

Furthermore, since the blackout curtain material has springs sewn into it, it prevents the curtain from bending and distorting as it expands and contracts, and has the effect of ensuring that the curtain is stretched evenly and that it can extend and contract smoothly.
