Description

[Detailed Description of the Invention] The present invention relates to a window shoji drawing device that automatically closes a window by simply closing the shoji.

Conventionally, pulling devices that press the shoji indoors or outdoors using parts attached to the window frame to airtightly close the shoji when the shoji is closed are already known, and many proposals have been made. .

However, conventional products have complex shapes, lack strength, and are difficult to manufacture, so they often break or deform during use.
It lacked reliability.

Furthermore, it was troublesome to attach the parts to the shoji or window frame.

This idea simplifies the shape of the parts to be attached to the shoji or window frame, improves reliability by providing strength, and also allows for easy attachment of the window shoji to the shoji or window frame. The purpose is to provide equipment.

Embodiments of the present invention will be specifically described below based on the drawings.

The window frames are the same as before: upper frame 1, lower frame 2, left and right vertical frames 3,
3 are connected in a rectangular shape, and the guide groove 4. An inner shoji fitting part consisting of a rail 5 of the lower frame 2 and concave grooves 6 opening opposite to each other in both vertical frames, and a guide groove 3a of the upper frame 1 as well.
, an outer shoji fitting part consisting of a rail 5a of the lower frame 2 and concave grooves 6a opening opposite to each other in both vertical frames, a guide groove 1 added to the outdoor end of the upper frame 1, and a lower frame. 2 rail 8,
It has a screen door fitting part made up of a door stop part 9 of both vertical frames, and each shoji and screen door can be opened and closed freely as in the conventional case.

In this case, the fitting and holding structure of each shoji and screen door is simply a line, and the present invention can be applied to any known structure other than those shown.

The guides and sliders, which are the main parts of the window shoji pulling device based on the present invention, which will be described later, will also be explained based on an example configured to fit the illustrated shoji fitting structure. It goes without saying that the scales can take on rounded shapes as appropriate depending on the structure.

Now, the guide 9, which is one of the main parts of the device according to the present invention, is provided in the guide grooves 4, 4a of the upper frame at a position corresponding to at least one end in the longitudinal direction of the upper end of each shoji when closed. Alternatively, the guide 9 is also provided on the upper surfaces 10, 10 of the lower frame at a position corresponding to at least one end in the longitudinal direction of the lower end of each shoji when closed.

Further, the guide 9 may be provided on both the upper frame and the lower frame.

When the guides are provided on both the upper and lower ends and are provided at one end in the longitudinal direction, the positions of the respective guides on the upper and lower ends correspond in the longitudinal direction.

Although the guide attached to the upper frame and the guide attached to the lower frame may be made of the same member, in this embodiment, the guide indicated by reference numeral 9 in FIG. 4 is used as the guide for the upper frame. Further, as the guide for the lower frame, the one shown with reference numeral 11 in FIG. 5 is used.

The former is made of plastic, and the latter is made of metal.

The upper frame guide 9 has a side wall 13.13 facing the bottom plate 12.
A is a member having a U-shaped cross section and a passage between both side walls, and one side wall 13a has a guide surface with a trapezoidal cross section in which the top surface 14 protrudes toward the opposite side wall 13. It has 15.

Then, the guide 9 has the top surface 14 protruding in the direction in which you want to pull the shoji, and with the passage opening downward,
It is fixed to the guide grooves 4, 4a of the upper frame.

The lower frame guide 11 has substantially the same shape as the upper frame guide 9, but has a circular arc cross section instead of a trapezoidal cross section.

The passage formed between the arc-shaped guide surface 15' and the side wall 13 opposite to this guide surface is opened toward the hillside, and the guide surface 15' faces in the direction in which you want to draw the shoji, and is directed downward. It is fixed inside each shoji sliding surface of the frame.

In the lower frame shown, the inner shoji guide 11 is the rail 5
The outer shoji guide 11a is provided in the recess between the tray/L/5a and the stepped portion 17.

On the other hand, as shown in FIG. 6 as a - row, the slider 18 has a fixing part 19 for inserting and attaching it into the hollow part of the vertical stile of each shoji, and a fixing part 19 at one end of this fixing part 19. The contact portion 21 is integrally formed with the portion 19 and has a tapered surface 20 diagonally crossing the sliding direction of the shoji.

The slider 18 inserts the fixing part 19 into the hollow part of the vertical stile 22, and with the abutment part 21 protruding upward from the upper end 23 of the vertical stile 22, the slider 18 moves the fixing part from the outer side of the vertical stile. 1
It is fixed by screwing machine screw S into 9.

In this case, the tapered surface 20 of the abutting portion 21 is attached so as to face in the opposite direction from the top surface 14 of the guide 90.

Similarly, when attaching to the lower end of a vertical stile, the fixing part is inserted into the hollow part of the vertical stile, the abutment part is made to protrude downward from the lower end surface of the vertical stile, and the tapered surface is connected to the lower end of the vertical stile. Fix it so that it faces in the opposite direction to the guide surface of the guide.

In addition, when adopting a continuous stile assembly structure by inserting both longitudinal ends of the upper and lower stile from the notched part of the upper and lower ends of the vertical stile, the slider should be inserted with the fixing part 19 into the upper and lower stile. Fixed.

As described above, one slider is attached to each guide in a corresponding manner.

With the above-described structure, when the shoji is closed, the tapered surface 20 of the slider contacting portion contacts the guide surface 15 of the guide 9, as clearly shown in FIG. 7, just before the shoji is completely closed. As the shoji progresses, the collision part 21 slides on the guide surface 15, so that the shoji gradually moves in the direction in which the guide surface protrudes (upward in the figure) with respect to the sliding direction of the shoji.
biased toward

In the completely closed state, the abutting portion 21 is stably abutted and locked on the top surface 14 of the guide surface.

Therefore, the shoji to which this slider is fixed is pressed against the indoor side or the outdoor side of the window frame.

In the illustrated embodiment, when the shoji is closed, the upper part of the inner shoji is biased toward the outdoors, the lower part of the inner shoji is biased toward the interior, and both the upper and lower parts of the outer shoji are biased toward the interior. The guide and the slider are attached in this way.

Therefore, the inner shoji consists of an airtight material 25 installed on the upper stile and a partition wall 26.
However, the airtight material 27 and rain return 16 provided on the lower stile are also the same as the airtight material 15a on the upper stile and the partition wall 26 on the outer shoji.
However, the airtight material 27a of the lower stile and the stepped portion 17 come into contact with each other, and an airtight effect is obtained.

Reference numeral 28 denotes an auxiliary pulling member that pulls the vertical stile 29 on the door stop side of the inner shoji toward the outdoors. An airtight effect can be obtained between the two.

Further, reference numeral 28a is a similar auxiliary pulling member that pulls the vertical stile 29a on the door stop side of the outside shoji toward the room, thereby obtaining an airtight effect via the airtight material 31a.

Also, between the stiles in the joint section, airtight material 32. 33°34.
35 and the smoke return 36 ensure the airtightness of the joining part.

Finally, if you rotate the crescent shape (not shown),
Adds an airtight effect.

As mentioned above, the guide according to the present invention is formed in a U-shape with a bottom plate and both side walls, and one side wall is provided with a guide surface protruding toward the other side wall, so the structure is extremely simple. It is easy to manufacture and attach to the upper frame and lower frame, and can be made thick enough to withstand collision force.

In addition, the slider has a fixing part that is inserted and fixed into the hollow part of the vertical stile or the hollow part of the lower stile, and is integrally formed with this fixing part, and has a tapered surface diagonal to the sliding direction of the shoji. , and an abutting portion that can move within the guide passage, the slider has a simple structure, is easy to manufacture, and is easy to make as a vertical stile or lower stile, and can also improve strength.
