[0002]

2. Description of the Related Art Conventionally, a semicircular window portion as described above.
Is smaller than the horizontally long windows in living rooms and corridors.
Due to the small light area, for example, it was formed to have appropriate transmittance
A light-shielding panel made of synthetic resin or tempered glass is attached.
ing.

[0003]

[Problem to be solved by the invention] However, as described above,
A place where sunlight coming in from windows is blocked by only light-blocking panels
The intensity of sunlight entering through the window depends on the season and time
However, the transmittance of the light shielding panel is always constant.
The room temperature may be higher than necessary due to sunlight
The furniture, pillars, floor, etc. around the window may become discolored.
Variable the amount of sunlight entering through the window
It has a problem that it cannot be knotted.

[0004] Further , as a means for solving the above problems,
Therefore, for example, a commercially available curtain is applied to a semicircular window.
When suspended, curtain curtains installed on the curved side frame of the window
The curtains open and close in the horizontal direction along the
Curtain rails and curtains will protrude more than
With the problem that the design of the window is impaired
I have.

[0005] By this invention has been made in view of the above problems, to open and close the curtain fan along the curved side frame portions of the window portions having a semi-circular shape, curtain to the window portion of such a specific shape
Can be freely opened and closed, allowing for any amount of light
It is an object of the present invention to provide a fan-shaped curtain opening and closing device that can be adjusted and adjusted .

[0006]

According to the invention, one edge of a curtain is hung openably and closably on a curved side frame portion of a window formed in a semicircular shape, and a straight side frame portion of the window portion is hung. It is a fan-shaped curtain opening / closing device in which the other end side edges of the curtain are converged and connected and fixed at a central position where the left and right are equally divided.

[0007]

According to the invention, a window having a semicircular shape is provided.
Open and close the curtain in a fan shape along the curved side frame
Then, like the conventional example, the curtain rail or curtain
Does not protrude or the design of the window is impaired.
The curtain can be opened and closed freely for windows with unique shapes such as
The amount of sunlight that enters through the window.
It can be variably adjusted at will.

In addition, the amount of sunlight entering through the window is
Room temperature is required because it can be adjusted variably according to nodes and time
Furniture, pillars, floor, etc. around windows become discolored
Can be prevented, and the purpose and effectiveness of the curtain
Fruit can be achieved.

An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a fan-shaped curtain opening / closing device according to a first embodiment for opening and closing two curtains suspended from a semicircular window in a fan shape. In FIG.
A curtain rail 3 is erected along the curved side frame portion 2a of the window portion 2 formed in a semicircular shape, and inserted into the curtain rail 3 .
Left and right top runners 4 and 4 and each hanging runner 5
Each upper side edge of each curtain 6,6 two relative ... 6
a, 6a, respectively, and the straight side frame portion 2b of the window portion 2
Each of the two curtains 6, 6 with respect to the bundle fitting 7 fixed to
Are connected to the lower end side edges 6b, 6b, respectively.

The above-described curtains 6 and 6 correspond to FIGS.
As shown in FIG. 3, guide pulleys 8 are provided on both left and right ends of a curtain rail 3 erected along the curved side frame 2a of the window 2.
The left and right ends of a loop-shaped opening / closing cord 9 supported between the guide pulleys 8 and 8 are fixed to the leading runners 4 and 4, respectively, and inserted into the center of the curtain rail 3. The top runners 4 and 4 and the hanging runners 5 inserted at the left and right ends of the curtain rail 3 respectively have the upper ends of the curtains 6 and 6 formed to have a size and shape that cover the window 2 half surface. A convergence bracket 7 that hangs the edges 6a and 6a, respectively, and that is fixed to a center position where the straight side frame 2b of the window 2 is divided into right and left.
The lower edge portions 6b, 6b of the respective curtains 6, 6 are bundled together and fixedly connected, and the straight side frame portion 2b of the window 2 and the respective fixed side edges 6c, 6c of the respective curtains 6, 6 are fixed. And are fixed so that they cannot be opened with Velcro.

A large-diameter drive pulley 10 is connected and fixed to the shaft end of a guide pulley 8 which is pivotally supported on the right end of the curtain rail 3, and a loop-shaped operation cord 11 stretched over the drive pulley 10. The rotating position is locked and unlocked by a clutch mechanism (not shown) built in the shaft of the drive pulley 10 while hanging down to the right end of the curtain rail 3.

Assuming that the illustrated embodiment is configured as described above, the opening and closing operation of the fan-shaped curtain opening and closing device 1 will be described below. First, as shown in FIG.
When deploying, the operation cord 11 hanging down to the right end of the curtain rail 3 is pulled down, and the opening / closing cord 9 stretched between the left and right guide pulleys 8 is rotated in the closing direction. The leading runners 4, 4 connected and fixed to the left and right ends of the opening / closing cord 9 are slid in opposing directions, and two pieces are centered on the bundle fitting 7 fixed to the linear side frame 2b of the window 2. Curtains 6 and 6 are sequentially developed in a fan shape, and the curtain rail 3
By overlapping each of the curtains 6 and 6 at an intermediate position between the two, the entire window portion 2 can be covered with the two curtains 6 and 6.

Next, when the two curtains 6, 6 are to be bundled, the other end of the operation cord 11 hanging down to the right end of the curtain rail 3 is pulled down, so that the left and right guide pulleys 8, 8 are pulled down. Each of the leading runners 4 and 4 fixedly connected to the left and right ends of the opening / closing cord 9 by rotating the opening / closing cord 9 stretched therebetween in the opening direction.
Are slid in the direction in which the curtains are separated from each other, and two curtains 6 each having a focusing bracket 7 fixed to the linear side frame 2b of the window 2 as a center.
The entire window portion 2 can be released by sequentially converging 6 at the left and right positions.

Thus, the bay of the window 2 having a semicircular shape
The two curtains 6, 6 are fan-shaped along the curved side frame 2a.
It can be opened and closed, so that the curtain
3 and the curtains 6, 6 protrude, and the design of the window 2
The window 2 having such a unique shape is not impaired.
And each curtain 6, 6 can be attached freely open and close.
Arbitrarily adjusts the amount of sunlight that enters through the window 2
can do.

Moreover, the amount of sunlight entering through the window is
Room temperature is required because it can be adjusted variably according to nodes and time
Furniture, pillars, floor, etc. around windows become discolored
And the purpose of each curtain 6, 6
And effects can be achieved.
