Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a screen deploying device that is attached to a window such as a bay window with a side surface or a solarium.

[0002]

[Prior art]

 Conventionally, as a method of blocking the sunlight entering from the bay window as described above, for example, a commercially available screen, blind, curtain, etc. are hung on the vertical window section under the bay window, and the inclination of the upper window is tilted. There is a light-shielding method in which a light-shielding panel made of synthetic resin, tempered glass, or the like having an appropriate transmittance is attached to the window.

[0003]

[Problems to be solved by the device]

 However, as described above, when the sunlight entering from the slanted window above the exit window is shielded only by the light-shielding panel, the intensity of the sunlight entering the exit window changes depending on the season and time. Since the transmittance is always constant, the indoor temperature may rise more than necessary due to sunlight entering from the inclined window, and the furniture, columns, floors, etc. around the window may discolor in a short period of time. However, there is a problem in that it is not possible to variably adjust the amount of sunlight incident from the inclined window.

Further, as a means for solving the above-mentioned problems, for example, when a light-shielding curtain such as a screen, a blind, or a curtain is stretched over a slanted window portion above the exit window, the light-shielding curtain is caused by its own weight. It is difficult to block the sunlight entering from the slanted window with the light-shielding curtain because it droops and a gap larger than necessary is formed between the facing surfaces of the slanted window and the light-shielding curtain. There is a problem.

In view of the above problems, the present invention develops the screens along the left and right deployment guides that are installed on the tilted window portion and the vertical window portion that form the window portion, thereby providing the tilted window portion and the vertical window portion. It is an object of the present invention to provide a screen developing device capable of preventing the surface facing each screen from being separated more than necessary and variably adjusting the amount of light shielding.

[0006]

[Means for Solving the Problems]

 In this invention, each winding shaft is mounted on the upper end side window frame of the inclined window formed on the upper side of the window and the lower end side frame of the vertical window formed on the lower side of the window, and the inclined window and A screen formed in a size and shape that covers the inclined window and the vertical window is wound around each take-up shaft mounted on the vertical window, and the left and right window frames and the vertical window of the inclined window are respectively wound. Both the left and right ends of each screen are unfoldably mounted on each unfolding guide installed on the left and right window frames, and the screen unfolding means is equipped with a screen unfolding device that regulates the unfolding of the above screens at arbitrary positions on each rail guide. It is a device.

[0007]

[Action]

 According to this invention, by operating the screen expanding means, each screen is expanded along each expansion guide installed on the left and right window frames of the slanted window part and the left and right window frames of the vertical window part that constitute the window part. After deploying each screen to an arbitrary position or to a position where the screens overlap each other, operate the screen deploying means to place on each deployment guide installed on the left and right window frames of the inclined window and the left and right window frames of the vertical window. By unfolding and fixing each screen at an arbitrary position, part or all of the inclined window part and the vertical window part that form the window part can be covered with each screen.

[0008]

[Effect of device]

 According to this invention, since each screen is developed along the inclined window portion and the vertical window portion forming the window portion, the facing surfaces of the inclined window portion and the vertical window portion and each screen are separated from each other more than necessary. It is possible to prevent the above, and variably adjust the sunlight incident from the inclined window portion and the vertical window portion to an arbitrary amount of light shielding. Moreover, since the amount of sunlight incident from the slanted window and the vertical window is variably adjusted according to the season and time, the indoor temperature becomes higher than necessary due to the sunlight incident from the exit window as in the conventional example. It is also possible to prevent discoloration of furniture, pillars, floors, etc. around the windows, and achieve the purpose and effect as a screen.
