DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sunshade device for prefabricated buildings such as sunrooms and greenhouses.

Conventional technology As a conventional first device, for example,
As disclosed in Publication No. 114794, left and right rails extending in the front and back direction are fixed to the roof surface,
It is known that a shade panel is movably supported on both rails over the entire length of the rail.

In addition, as a conventional second device,
As disclosed in Publication No. 68002, a panel frame is fixed to the peripheral edge of the roof surface, and a plurality of sunshade panels are supported on the panel frame so as to be movable at multiple levels above and below. Things are known.

Problems to be Solved by the Invention In the first conventional device described above, by moving the sunshade panel, the place where the sunshade panel can shade the sun can be changed; Area cannot be changed. Moreover, changing the location where the sun can be avoided is restricted by the length of the rail.

In addition, in the conventional second device described above, the area that can be shaded from sunlight by the sunshade panel can be changed by opening and closing the panel frame with multiple sunshade panels; The location cannot be changed.

An object of the present invention is to provide a convenient sunshading device for a building that can change both the location and area that can be shaded from sunlight by a sunshade panel.

Means for Solving the Problems In the sunshade device for a building according to the present invention, left and right main rails extending in the front-rear direction are fixed to the roof surface, and left and right auxiliary rails are attached to both main rails, and the left and right auxiliary rails cover the front portions of each of the main rails. The lower shade panel is supported movably so that it can be moved forward and retracted from the front end of the main rail, the lower shade panel is supported by both auxiliary rails so that it can be moved along the entire length of both auxiliary rails, and the upper shade panel is supported by both auxiliary rails so that it can be moved forward. It is fixed to both auxiliary rails so as to straddle the rear part of the lower awning panel movement route.

Function The sunshade device for a building according to the present invention has the following features:
The left and right main rails extending in the front-back direction are fixed to the roof surface, and the left and right auxiliary rails are movably supported by both main rails, so that the lower awning panel can be moved over the entire length of both auxiliary rails. The upper sunshade panel is fixed to both auxiliary rails so as to straddle the rear of the lower sunshade panel movement path, so when the auxiliary rail is moved relative to the main rail, the sunshade panel is The area that can be shaded from sunlight by the shade panel is changed, and when the lower shade panel is advanced or retreated from below the upper shade panel, the area that can be shaded from sunlight is changed.

Furthermore, since the front part of the auxiliary rail can freely move forward and retract from the front ends of both main rails, changing the location protected from sunlight by the sunshade panel is not restricted by the length of the main rail.

The sunshade panel opening/closing tool 13 is similar to an automatically telescopic antenna for a car, and therefore consists of a main body 59 equipped with a motor, etc., and a telescopic multi-stage rod 60 extending forward from the main body 59. A mounting bracket 62 is mounted on the front and rear square cylindrical support member 61 that is fixed to the left and right side walls at the front and back of the interior.
Supported through. A downward protruding portion 63 is provided on the lower surface of the front support member 61, and this serves as an engaging portion to which the first sunshade panel 8 is attached.
The engaging portion 27a engages when the handle moves forward.

A bracket 64 is attached to the front end of the third sunshade panel 11.
are fixed, and a rod receiving plate 65,
66 is fixed. The bracket 64 has a substantially triangular shape when viewed from the front and rear directions, and its top is the first
It protrudes above the sunshade panel 8 and reaches the height of the rod 60, and the tip of the rod 60 is fitted into the top of the rod 60, and a bolt 67 is inserted to hold it down.
As a result, the tip of the rod 60 is connected to the bracket 64. The tops of both rod receiving plates 65, 66 extend to approximately the same height as the bracket 64. Both rod receiving plates 65, 66
U-shaped notches 68, 69 are provided at the top of the holder, and U-shaped rod receiving members 70, 71 are fitted to the edges of the notches 68, 69. Furthermore, cushion members 72 and 73 are attached to the front lower ends of both rod receiving plates 65 and 66, respectively.

When the sunshade panel opening/closing tool 13 is operated to cause the rod 60 to protrude from the state shown in FIG. 3, first the third sunshade panel 11 moves forward. When the engaging portion 54a of the third sunshade panel 11 is engaged with the front frame member 37 of the second sunshade panel 9, the second sunshade panel 9 moves together with the third sunshade panel 11. . Next, when the engaging portion 39a of the second sunshade panel 9 is engaged with the front frame member 21 of the first sunshade panel 8, the first sunshade panel 8 moves together with the second sunshade panel 9. do. In this way, each sunshade panel 8,
9 and 11 are sequentially moved forward from the bottom one. And the engaging portion 2 of the first sunshade panel 8
7a is engaged with the engaging portion 63 of the sunshade panel opening/closing device support member 61, each of the sunshade panels 8, 9, 1
1 stops. In this state, the second sunshade panel 9 has almost reached the front end of the main rail 7, and the third sunshade panel 11 projects in front of the main rail 7.

When the rod 60 is moved back and forth from the above-mentioned state, the third sunshade panel 11 moves rearward, and the bracket 64 attached to it moves in the order of the second sunshade panel 9 and the first sunshade panel 8. As the bracket 64 moves, the third sunshade panel 11 and the first and second sunshield panels 8 and 9 are successively moved rearward. When each sunshade panel 8, 9, 11 is stacked vertically as shown in FIG.
Stop the movement of 1.

Effects of the Invention According to this invention, when the auxiliary rail is moved with respect to the main rail, the location where the sunshade panel can shade the sun is changed, and the lower sunshade panel is placed below the upper sunshade panel. When the sunshade panel is moved forward or backward, the area that can be shaded from sunlight is changed, so a convenient sunshade device is provided in which both the area and the area that can be shaded from sunlight can be changed by the sunshade panel.

Furthermore, since changing the location where the sunshade panel can shade the sun is not restricted by the length of the main rail, the sunshade panel can shade the sun to an extent that exceeds the length of the main rail.
