Description

[Detailed Description of the Invention] This invention relates to a window blinding device that covers a part of the window and serves as a blindfold when the window is opened.

Generally, shoji screens are attached to window openings in buildings so that they can be opened and closed, but windows in bathrooms, toilets, etc. need to be ventilated to prevent steam and odors from entering the room when in use. Despite this, people usually do not open the shoji doors and leave them closed to prevent people from seeing them. In response to this, a blindfold device has been proposed and implemented in which a number of slats are diagonally attached at regular intervals on the outdoor side of the window. However, although such a blindfold device allows ventilation, it does not allow sunlight to enter the room, making the room dark. Recently, opening/closing louvers with movable blades have been commercially available, but they are very expensive.

The purpose of this invention is to solve the above-mentioned drawbacks and, in particular, to propose a window blinding device that can provide sufficient lighting and ventilation and can be manufactured at low cost.

In the figure, symbol A indicates a window. This window A is a window frame B attached to a window opening opened in the building frame.
It is comprised of sliding sliding screens 2, 2 which are attached to the window frame B so as to be openable and closable, and blindfold members 3, 3 which cover both left and right sides of the window opening.

The window openings are the upper and lower window sills 10 and 11 and the pillars 1 on both sides.
2 and 12.

The window frame B is a rectangular frame made up of upper and lower frames 20, 21 and left and right vertical frames 22, 22, each formed from an extruded material of aluminum or its alloy.
The indoor sides of the upper and lower frames 20 and 21 are shoji screens 2 and 2, respectively.
Rails 23, 23 for sliding are formed, and rails 24, 25 for screen door are formed on the outdoor side.

Sliding shoji 2 and 2 are respectively rail 2 of window frame B
3 and 23 so as to be slidable.

In addition, 30 is an interior material, 31 is an exterior material, and 3
2 is a picture frame.

The blindfold members 3, 3 each include a box-shaped bulge 3a having an appropriate width, and bulges 3b, 3b formed above and below the bulge 3a. Three sides of the bulging portion 3a are closed, and one side 3c is closed.
is open. Receiving grooves 35, 35 are formed at the ends of the projecting parts 3b, 3b. Such blinding members 3, 3 can be easily molded from an opaque or translucent synthetic resin material. Opening part 3
It is preferable to reinforce the relatively weak parts like c with reinforcing material.

When attaching the blindfold members 3, 3 having the above configuration to the window frame B, the projecting portion 3 of the blindfold members 3, 3
Using the screen rails 24, 25 of the window frame B, fit the receiving grooves 35, 35 into the screen door rails 24, 25 of the upper frame 20 and lower frame 21 in a so-called kendon style or lifting style. Just put it in. Thereafter, by sliding the blindfold members 3, 3 to both sides of the window frame B, they can be attached to a predetermined position. Incidentally, in order to prevent the blind members 3, 3 from wobbling, a gasket or the like may be installed in the receiving groove 35 of the blind members 3, 3.
Further, the blind members 3, 3 can also be fixed to the window frame B by adhesion or by screwing appropriate parts.

With the above configuration, synthetic resin blindfold members 3, 3 are disposed on the outdoor side of the side portions of the window opening, which cover both side portions of the window opening without any gaps to the extent that it is impossible to look into the window opening. A bulging portion 3 is provided between the blindfold members 3, 3 and the outdoor surface of the double sliding shoji 2, 2.
A gap corresponding to the distances a and 3a is formed, and the ends 3c and 3 on the center side of the window opening in the sliding shoji 2 and the blindfold members 3 and 3 are formed.
c (see FIG. 3) is opened. Therefore, first of all, the sliding shoji 2, 2 are attached to the blindfold members 3, 3.
Even if it is opened within the width range, it is blocked from the outside by the blindfold members 3, and it is not possible to look into the inside. In addition, since one side 3c of the blindfold members 3, 3 is open, when the sliding shoji 2, 2 is opened, the indoor air communicates with the outside air through the open part 3c, making ventilation easy. . Moreover, in order to obtain the blindfold effect and ventilation effect, no operation is required other than opening the shoji.

Note that the mounting of the blindfold members 3, 3 is not necessarily limited to the example illustrated above, and as shown in FIG. When the upper frame 20 or the lower frame 21 of the frame B has a dedicated rail for attaching the blindfold member, there is no need to use the screen door rail. Furthermore, the blindfold member 3 may be attached directly to the screen door 40 as shown in FIGS. 5a and 5b. In this case, inward mounting grooves 43 are formed on the outdoor surfaces of the upper stile 41, lower stile and one vertical stile 42 of the screen door 40, and the upper and side parts of the blindfold member 3 are projected into the mounting grooves 43. The parts 3a and 3d may be fitted and attached, or they may be fixed directly to the upper and lower frames and vertical frames of the screen door by screwing, gluing, or the like. If the screen door covers the entire surface of the window opening, the blinding member may be attached to both sides of the window opening, and if the screen door is configured to be slidable, it is only necessary to attach it to one side.

Further, blind members 3, 3 may be provided on the outside of the window frame B together with members such as a grid 50, as shown in FIG.

As explained in detail above, the window blindfold device according to the invention includes a sliding shoji that is slidably housed inside a window opening provided in a building, and a sliding shoji that is slidably housed inside a window opening provided in a building. A blinding member made of synthetic resin is placed on the outside to cover the side of the window opening without a gap to the extent that it is impossible to see through, while a certain gap is provided between the blinding member and the outdoor surface of the sliding shoji. , and the space between the double sliding shoji and the central end of the window opening in the blindfold member is open, so that the double sliding shoji can be slid within the width of the blindfold member. Even if it is opened, the inside is blocked from the outside by a blindfold member and cannot be seen inside. Furthermore, when the sliding shoji is opened, the indoor and outdoor areas are communicated through the open side portion of the blindfold member, so ventilation can be easily and reliably performed. Moreover, in order to obtain the blindfold and ventilation effects, no operation is required other than opening the shoji. Furthermore, since the blindfold member is molded from synthetic resin, it allows light to pass through and has good lighting performance, and can be manufactured at low cost.The mounting structure is also simple, so construction is easy.
