Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a window device and a blind device which is arranged in windows of a building such as a detached house or an apartment house, and blinds the windows if necessary.

[0002]

A blind device of this type is usually constructed by arranging a blind composed of a plurality of slats juxtaposed in the vertical direction above and lowering the blind from above by the operation of a lifting device. The window and the like are blindfolded, and the blind is raised by the reverse operation of the lifting device to open (open) the opening.

By the way, in such a blind device, since the accommodating portion for accommodating the slats is arranged above the opening of the building when the opening is opened, the degree of opening of the opening of the building is reduced by the accommodating portion. Therefore, even if the blind is raised to open the opening, a sufficient feeling of opening may not be obtained. Therefore, there has been proposed a blind device in which a blind is arranged below when the opening is opened and the upper end of the blind is lifted when the opening is closed (closed).

In the blind device according to this proposal, since it is possible to omit the accommodating portion arranged above the opening of the building, it is extremely preferable that a sufficient open feeling can be obtained at the time of opening the opening. Manually operable ball chains, e.g. to raise the blinds, are usually placed outside the screen doors to avoid touching the building frame, so that when the blinds open and close the opening There is no choice but to open the once and manually operate the ball chain.

However, it is extremely troublesome to open the shoji every time the blind is opened and closed, and in addition, when air conditioning, heating, cooling, etc. are provided in the room, these are useless, and moreover, If the ball chain hangs on the outside of the shoji screen, it is not preferable for crime prevention.

The present invention has been made in view of the above points, and it is an object of the present invention to open and close an opening portion by a blind without opening and closing a shoji.
An object of the present invention is to provide a structure of a blind device and a window frame that can be easily installed without additional work on the building frame.

By rotating the pulley 203 by rotating the pulleys 203 in the same direction, the rod 61 can be rotated in the R3 and R4 directions as described above through the rotation of the small gear 206 and the large gear 207. The opening 16 can be opened and closed by the blind 5 without opening and closing the shoji 93 installed in the window frame 8 on which the through holes 94 and 95 are formed.
It is possible to install it by simply using No. 1 without additional modification to the building skeleton 85.

Further, the blind device 1 and the window frame 81 described above are used.
In the above structure, the bevel gear 87 is directly fixed to the other end 64 of the rod 61 to form the rotation transmitting means 65. Instead of this, as shown in FIG. 13, the bevel gear 87 and the other end of the rod 61 are replaced. The universal joint 211 is interposed between the portion 64 and the one end of the universal joint 211 to the bevel gear 87,
The other end may be connected to the other end 64 of the operating rod 69 to configure the rotation transmitting means 65. In this case, the universal joint 211 is rotatably supported by the cover member 67 via the bearing 68. Has been done.

According to the rotation transmission means 65 shown in FIG. 13,
The vertical positional relationship between the blind device 1 and the window frame 81 can be appropriately set.

[0053]

According to the present invention, the blind device can be opened and closed by the blind without opening and closing the shoji screen, and can be installed without additional work on the building frame. A structure with a window frame can be provided.
