Description

[Detailed Description of the Invention] The present invention relates to a watertight device for the joining part of a sliding shoji door suitable for a sliding shoji door that uses an internal fitting method.

In the case of sliding shoji sashes that use an internal fitting method, that is, a type in which the shoji is installed and removed from the indoor side, the ease of installation and removal is usually at odds with the watertightness of the area. That is,
In this method, unlike the external fitting method, when installing the shoji, the lower end of the shoji is once swallowed into the groove between the bottom frame rails, so if there is a windstop in the groove, the installation of the shoji will be difficult. On the other hand, if a windshield plate is not provided, the watertightness will be reduced. As a means to solve this problem, it has been proposed to install a windshield plate in a slidable manner, but it is troublesome to have to move the windshield plate every time the shoji is installed or removed.

This point was skillfully resolved in Jikoko 54-18848.
The gist of the technique is to fit and fix a rectangular windshield plate that can be elastically deformed by pressing into the groove. However, this technique requires drilling holes in the rail itself in order to lock one end of the rectangular windshield plate, and above all, if the lower frame is of a stepped type, it is necessary to make a hole under the inner and outer shoji. The technique has a drawback that it cannot be applied because the lower ends of the frames are uneven.

Therefore, this invention was developed for sliding sliding shoji satsushi.
To provide a watertight device for a joining part of a sliding sliding shoji which is suitable not only for an external fitting method but also for an internal fitting method and can be applied even when the lower frame is of a stepped type. The present invention will be explained below based on a specific example in which the present invention is applied to a stepped lower frame.

As shown in FIGS. 1 and 2, the watertight device according to the present invention has a step-type lower frame 1,
A wind stopper 10 is fixed to a position in a groove 4 between the lower frame rails 2 and 3 and facing the lower end surfaces of the sliding doors 5 and 6.

As shown in FIG. 3, the wind stopper 10 further includes a wind stopper main body 11 that is fitted and fixed in the groove 4, and a plurality of elastic thin plate-shaped airtight members erected upward from the main body 11. 12, 12, and in this example, since the lower frame 1 is of a stepped type, the lower edges of the shoji lower stile 5a, 6a are uneven and uneven, so the main body 11 is located inside the shoji lower stile 5a, 6a. , a main body portion 11a for an inner shoji and a main body portion 11b for an outer shoji, corresponding to the lower edge of each lower stile facing the groove 4.
are formed in different steps, and these portions 11
The upper surfaces of a and 11b are formed so as to be located slightly below the lower edge of each corresponding lower stile. Airtight members 12 and 1 are installed upright on each main body portion 11a and 11b.
2 is formed with a positional relationship such that its upper edge is pressed into contact with the combined lower end surfaces of the shoji 5 and 6.

In addition, the wind stop main body 11 is entirely made of an elastic material such as soft plastic or rubber in this example, but the inner shoji 5 shown in FIG.
It is only necessary that only the portion that requires pressing deformation when attaching and detaching the main body 11, that is, at least the upper portion of the main body 11, be made of an elastic material.

Note that the inner shoji 5 is formed such that the lower edge of the indoor side wall of the lower stile 5a is located above the lower edge of the outdoor side wall. Then, attach the lower part of the inner shoji to the groove 4.
The lower end of the indoor side wall of the lower stile is placed on the main body part 11a of the wind stopper 10, and the lower end of the outdoor side wall of the lower stile is placed on the main body part 11b, respectively, when the lower stile is dropped into the main body part 11b. There is. When configured in this way, the lower part of the inner shoji 5 can be adapted to the stepped wind stopper 10.

FIG. 5 is a diagram showing another embodiment of the wind stopper 10,
In this example, airtight materials 12a, 12a are also provided on the vertical wall of the main body portion 11a for the inner shoji screen. When the airtight material 12a is provided in this way, the airtightness of the outer shoji 6 against the stile is further improved.

In the watertight device of the present invention constructed as described above, when the sliding doors 5 and 6 are closed, the airtight materials 12 and 12 of the wind stopper 10 are pressed against the lower end surface of the fitting. , 12 can prevent wind and rain from entering from outside.
Furthermore, since the airtight material 12 has a thin elastic plate shape, not only will it not cause any hindrance when the shoji 5 and 6 are moved, but also the wind stopper main body 11 is made of a soft elastic material at least in its upper part. Therefore, even if the sliding shoji sash adopts an internal fitting method, the presence of the wind stopper 10 has the advantage that the installation and removal work of the shoji will not be hindered.
It goes without saying that the present invention can also be applied to a non-step-type lower frame, and also to an external fitting type sliding shoji sash.
