Description

DETAILED DESCRIPTION OF THE INVENTION The present invention opens and closes along a vertically curved window that includes a horizontal window section or a sloped window section. This relates to a-le screen.

Conventionally, in order to use a roll screen for a tilted or horizontal window, a guide is required to support the raw fabric of the roll screen tilted or horizontally. In order to shade Kei, who was spoiled with vertical windows, with a single a-le screen, complicated guides and the like were required. In addition, in conventional roll screens for inclined windows or horizontal windows, when the roll screen is rolled up to let in sunlight, the guides and the like remain on the window surface, obstructing visibility.

The object of the present invention is to eliminate the drawbacks of the conventional roll screen used for windows bent in the high-vertical direction as described above, and to provide a self-propelled guide that supports the middle part of the raw cloth of the arus screen. As a type, it effectively prevents the raw cloth from hanging down without requiring a complicated guide mechanism, and also prevents any guides or other parts from remaining that may obstruct the field of vision when the raw cloth is rolled up. To provide a roll screen which can also be applied to windows in which horizontal, inclined and vertical window sections are combined.

The cool screen according to the present invention has guide rails bent along the window surface on both sides of the window, a winding cylinder for winding the raw fabric of the cool screen arranged above the guide rail, and the winding cylinder is provided with an operating member that rotates the cylindrical body in the direction in which the raw cloth is wound up, and a lower plate that is attached to the lower end of the raw cloth is slidably engaged with the guide rail on both sides. , A guide cooler supporting the J-jung in the raw cloth is slidably engaged with the guide rail on the upper side of the lower plate, and a spring mechanism is provided to pull down the guide cooler. The lower plate is pushed downward, and the winding cylinder is provided with a stopper that resists the action of the spring mechanism and stops the rotation of the core winding cylinder, and the guide roller is The guide rail is characterized by being arranged so as to stop at the bent part of the guide rail.

The temperature will be explained below with reference to one drawing.

Figure 1 shows an example of a window bent toward the high field, including a horizontal window part, an inclined window part, and a vertical window part.
2 shows a window, and 2 shows an a-le screen according to the invention attached to this window, and the window 1 consists of a horizontal window section 1a, an inclined fP+ window section 1b, and a vertical window section 1c.

Guide rails 6 bent along the window surface are installed on both sides of the window.
A winding cylinder 5 for winding up the raw cloth 4 of the a-le screen is arranged above the guide rail 6. As mentioned below,
The raw cloth 4 is provided with an operation cord 6 which always acts to pull it down (a pulling force is applied by a spring mechanism and rotates the cylindrical body 5 in the direction of winding up the raw cloth against this direction). A stopper 7 is provided which resists this force and stops the rotation of the °C cylinder 5.The structure of the stopper Z itself is irrelevant to the present invention, and the structure of the stopper Z itself is not related to the present invention. Since this is the proposed method and any mechanism can be used, a lengthy explanation is omitted here.

A lower plate 8 is attached to the lower end of the raw cloth 4, and the lower plate 8 is slidably engaged with the guide rail 6 at both ends. !
! Ta. Guy FC that supports the middle part of the raw cloth to prevent the image from falling down on the raw cloth 4! -29 is slidably engaged with the guide rail on the upper side of the lower plate.

The guide a-ra 9 is shown in the third factor, and includes a cylindrical guide pipe 1o at J:5, a torsion spring 11 installed in the cylindrical guide pipe, and a rotating shaft rotated by the elastic force of the torsion spring. 12 and a wheel 14 that winds up a guide cord 16 by rotating around a single rotating shaft.

The end of the guide pipe 10 is formed into a non-circular shape as shown in FIG. 4, and is engaged with the guide rail 6. Therefore, the guide a-ra 9 is slidably engaged with the guide rail 3, but cannot rotate. I can't do it anymore, Guy F Boil 1
The guide coat 15 is rotated by the action of a spring 11 with respect to the main body of the guide coater 15. The guide coat 15 is attached to the guide wheel 14 of the B pin at one end, and is attached to the lower part of the second rail at the n-s end.

Therefore, Guy FC! - The lever 9 is pulled downward by the action of the temporary spring 110, and the bottom &8 is pushed down to pull down the fabric 5 (However, as described above, the operating cord 6 is pulled downward against the action of the temporary spring 110. It acts on the cloth 5 to pull up the raw cloth 4. At the position where it has been pulled up in this way, the stopper 7 acts to hold the raw cloth at the pulled up position.

lOh, the above guide cooler 9 is attached to the bent portion 1 of the guide rail, for example #! It is constructed so that it stops at the position indicated by A in one turn and does not fall any further.

Next, the operation of the above roll screen will be explained.

First, it is assumed that the raw cloth 4 is in a pulled down state. When the operating cord F6 is operated to rotate the one-winding cylinder 5, the cloth 4 is sequentially rolled up, and the lower plate 8 moves upward within the guide rail 3.

When the lower plate 8 moves to the position where the guide roller 9 is stopped, the lower plate 8 moves while pushing the guide roller 9 upward.

When the guide roller 9 moves upward, the guide cord 15 is unwound from the wheel 1a, so that the wheel 14 moves within the guide rail 6 while rotating, thereby energizing the torsion spring 11. In this state, lower plate 8
When the operator pulls up the cord upward and releases the operation coat 6, the guide a-ra 9 tries to move downward while winding up the guide cord 16 due to the force of the swinging spring 11. Since the stopper device 7 prevents the rotation of the one-winding cylinder 5, it is stopped by the lower plate 8. When the stopper is released from this state, the guide Fe1-ra 9 moves along the guide rail 3 while winding up the guide F13 by the force of the spring 11 and pushing the lower plate 8 downward. When the guide roller 9 moves to the end of the guide coat 15, the guide roller 9 will stop at that position, and from then on, the lower plate 8 will move against the guide rail 3 due to the weight of the lower plate 8 and the raw cloth. descends to the lowest point.

In particular, a horizontal window section as in the illustrated embodiment.

A guide bar 1 that can freely slide along a guide rail 6 or in a window where an inclined window portion and a straight-view window portion are combined.
If the guide bar 15 is placed between the above-mentioned guide Fct-ra 9 and the lower plate 8 and kept at ℃, even if the slope of the window is gentle, the guide bar 15 will allow the weight of the lower plate 8 and the raw cloth to meet. It is possible to descend reliably and prevent the raw cloth from falling down at the bend 1fllB.

As mentioned above, in the cool screen according to the present invention, in order to prevent the raw cloth of the roll screen from sagging, the guy F that supports the middle part of the roll screen is of a self-propelled type, and the guy F is a complicated guy F.
is not necessary.

Furthermore, even when the crawl screen is raised, no guides or the like remain that cross the field of view, and the design is also excellent. Of course.

In addition to the above-mentioned self-propelled guy F, by providing an appropriate number of guys F that move downward due to their own weight.

It can also be used for horizontal, slanted, and mni windows.
