Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a blind that is attached to a window frame or the like and controls light entering a room from the window.

[Conventional technology]

In recent years, various types of double sashes with built-in blinds have been proposed to achieve energy-saving effects, but since ordinary blinds are installed inside the sashes, the rotating and lifting mechanisms of the blinds are complicated. There are problems such as high price.

[Purpose of invention]

The present invention aims to provide an inexpensive and completely new blind that has a simple structure and can be expected to have the same effect as the above-mentioned double sash.

[Summary of the idea]

The blind according to the present invention includes a transparent hollow pipe having a length substantially equal to the length of the hollow pipe.
It is characterized in that a plurality of cylindrical bodies equipped with flat light shielding plates are arranged and supported in a flat plate shape, and by rotating the cylindrical bodies, external light can be blocked or light can be let in.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is an exploded perspective view showing one embodiment of the blind of the present invention, in which 1 is a transparent hollow pipe, 2 is a flat light-shielding plate having a length approximately equal to the length of the hollow pipe, and 3 4 indicates a cap fitted to both ends of the hollow pipe, and 4 indicates a frame supporting the hollow pipe. In the embodiment shown in FIG. 1, the hollow pipe 1 is formed as a cylindrical pipe of a constant length, and has approximately the same length as the cylindrical hollow pipe 1.
A flat light shielding plate 2 is attached to the center of the hollow pipe. For this flat light-shielding plate 2, a slat made of a thin aluminum plate used in ordinary horizontal blinds may be used, but a thin plate made of other materials (iron, resin, wood, etc.) may also be used. good. Caps 3 are provided at both ends of the hollow pipe 1 to engage with the openings. This cap is pipe 1
A small diameter portion 3a having the same shape as the inner diameter of the pipe 1, a large diameter portion 3b having a larger diameter than the inner diameter of the pipe 1, and a side frame 4.
It consists of a shaft part 3c rotatably supported by a,
The small diameter portion 3a is provided with grooves 3d for receiving both ends of the light shielding plate installed inside the pipe (second groove 3d).
(see figure).

As mentioned above, the light shielding plate 2 is placed inside the cylindrical hollow pipe 1.
is installed and the openings at both ends of the pipe 1 are closed with caps 3 to form a shield, and an appropriate number of shields are supported horizontally between the side frames 4a to form a blind.

As shown in FIGS. 3 and 4, the rotation mechanism has an arm 5 fixed to the cap 3 of each shield.
This can be achieved by rotatably pivoting the end of the operating rod 6 to the operating rod 6 and moving the operating rod 6 up and down by appropriate means.

Further, as shown in Fig. 5, a gear 7 is provided on the cap 3, and each of these gears is meshed with the upper and lower gears via an intermediate gear, and by rotating this gear by an appropriate means, each shielding body is rotated. You may.

In addition, the pipe 1 is provided with a large number of through holes 8 as shown in Fig. 6, and by directing the through holes to the outside of the room or to the outside of the room, the warm air inside the pipe is released to the outside in the summer. In winter, the heating and cooling effect can be increased by bringing warm air inside the pipes into the room.

In addition, the shape of the pipe does not have to be circular,
It is also possible to use shapes as shown in FIG. 7 A, B, C, and D. In these cases, when the pipes are rotated, gaps are created between the pipes, allowing ventilation.

Moreover, in the form shown in FIG. 7D,
A light shielding plate can also be glued to the outer surface of the hollow pipe.

[Effect of idea]

As mentioned above, the present invention has a simple and inexpensive structure, has an air layer inside like conventional double sash built-in blinds, has excellent heat insulation effects, and can control external light blocking and lighting. Provide blinds.

Claims (1)

[Scope of utility model registration request] A plurality of cylindrical bodies each equipped with a flat light-shielding plate having a length approximately equal to the length of the hollow pipe are arranged and supported in a flat plate shape on a transparent hollow pipe, and external light is blocked by rotating the cylindrical bodies. , or blinds that let in sunlight.
