This invention relates to a retaining device for restraining and retaining the vertical stile of a shoji screen from the indoor side.

[Background technology and issues to be solved in the background technology]

As an example of the structure of a conventional restraining device for this type of general sliding sash window, an inner shoji on the indoor side located in the center of a three-panel shoji type is fitted and restrained in a dead shape, and the left and right sides are restrained. Figures 1 to 3 show the main structure of a sliding sash window in which only the outside shoji on the outside of the room can be opened and closed individually, and when this is applied to a bay window structure that also serves as lighting for a building. show.

1 and 2 are a cross-sectional view and a longitudinal sectional view of the general structure of the essential parts of a bay window structure to which this conventional device is applied, and FIG. 3 is an enlarged perspective view of the same fastening fitting. In each of these figures, reference numeral 1 indicates the entire bay window, 2 indicates the entire sliding sash window in the form of a three-panel shoji screen attached to the front part of the bay window 1, and 3 and 4 indicate the entire bay window. The base plate and the top plate of the bay window 1, 5, 5 are a sash window installed in the side part of the bay window 1 in a fitted type for lighting the side, 6 is the base of the bay window 1, and 7 is a sash window for side lighting. This is the roof of bay window 1.

Therefore, the window frame 11 of the three-panel shoji-type sliding sash window 2 has an upper and lower pair of upper and lower frames 12 and 13, and a pair of left and right frames that are attached directly to the front of the bay window 1. It consists of a vertical frame 14, and two outer shoji 17 and one inner shoji 18 built into this window frame 11 on outer and inner rail pieces 15 and 16 are also compatible with the outer shoji 17. It consists of an upper and lower pair of upper and lower stiles 19 and 20, and a pair of left and right vertical stiles 21 and 22, and the inner shoji 18 has an upper and lower stile.
It consists of a lower set of upper and lower stiles 23 and 24, and a pair of left and right stiles 25.

The two outer shoji 17 on the outer rail 15 described above are respectively positioned on the left and right sides of the window frame 11 in the closed state, and the one inner shoji 18 on the inner rail 16 is similarly positioned. It is located at the center of the window frame 11 in the closed state, and in this state, the central vertical stile 22 of each outer shoji 17 and the left and right vertical stile 25 of the inner shoji 18 are overlapped with each other, It forms a so-called connecting frame (hereinafter, each of these vertical frames will be referred to as a connecting frame 22 and 25, respectively),
Here, the inner shoji 18 at the center, which is on the indoor side, is fixed in that position and restrained in a fit-in shape, and the outer shoji 17, 17 on the left and right sides, which are on the indoor side
1 and 3, in order to open and close the outer rail 15 alternately on the outer rail 15, a retaining fitting 26, that is, a mounting seat 27,
Utilizing an L-shaped metal fitting that is integrally formed with a retaining seat 28 that stands up at right angles from this mounting seat 27,
By means of this retaining metal fitting 26, the upper and lower parts of at least one side stile 25 of the inner shoji 18 in the central part can be fixed.
For example, a set screw 29
They are attached and fixed to the opening/closing function.

However, in the configuration of such a conventional retaining device, the sash of the inner shoji in the center is fixed to the upper and lower frames of the window frame at the upper and lower parts using retaining metal fittings, such as screws, etc. Since the inner shoji in the center cannot be removed unless the retaining metal fittings are removed, the inner shoji cannot be removed. It is extremely inconvenient when cleaning the inner shoji and its surroundings or replacing the glass, and even if you remove the retaining metal fittings, if you do this frequently, there is a risk that the screw threads will be crushed and you will not be able to use them again. In addition, the workability of the installation and removal operations is extremely poor, and with this type of fixing means, the retaining metal fittings and the heads of the screws, which have a shape that does not fit through the holes, are exposed on the surface. In this respect, it also has the disadvantage of poor appearance, which is undesirable, and there is a need for improvement.

[Disclosure of invention]

In view of these shortcomings of the conventional retaining devices, this invention improves the fixing means for fitting and restraining the shoji in a fixed shape, and allows the shoji to be enclosed only from the indoor side, or the vertical stile if necessary. The object of the present invention is to provide a device configuration in which the shoji can be easily removed from the outside by restraining the shoji.
This retaining member is approximately U-shaped in cross section, consisting of a surface portion and side portions bent at right angles from both ends of the surface portion, and has tapping screw holes at each inner corner. The member is fitted from the inside of the room to the exposed surface of at least one vertical stile of the internal shoji screen, which is to be restrained by fitting and closing, over the entire length, and both ends of this retaining member are attached to the window frame. It is characterized in that it abuts against each extending portion of the upper frame and the lower frame, and is attached to each of the tapping screw holes with tapping screws.

〔Example〕

Hereinafter, one embodiment of the retaining device according to this invention will be described in detail with reference to FIGS. 4 to 7.

The embodiment devices shown in FIGS. 4 to 6 are shown corresponding to the conventional devices shown in FIGS. 1 to 3, and in the embodiments shown in FIGS. The same reference numerals as those in the conventional example in FIGS. 1 to 3 indicate the same or corresponding parts.

As the detailed structure of the retaining device 30 according to this embodiment is shown in FIG. A retaining member 31 is used which has a substantially U-shaped cross section and has tapping screw holes 34, 34 provided at each corner inside the ridge. And this retaining member 31
A stepped portion 35 is formed at the center of the surface portion 32 to give a change in appearance or other aspects, and a step portion 35 is formed at the center of the surface portion 32 to give a change in appearance or other aspects, and a step portion 35 is formed at the center of the surface portion 32, and a step portion 35 is formed in the center of the surface portion 32 to give a change in appearance or other aspects. It is advantageous to form protrusions 36, 36 for this purpose. Incidentally, as is well known, the retaining member 31 having such a cross-sectional shape can be manufactured at low cost by extruding an aluminum material through a mold, so-called a series of extruded sections in the longitudinal direction. It is possible to easily obtain the desired material by cutting the material into a predetermined size, and it may also be molded from, for example, a hard synthetic resin.

However, in the case of this embodiment device, the retaining member 31 having a predetermined size obtained in this manner is removed from the upper frame 12 and the lower frame 13 when the window frame 11 is framed. The inwardly extending extensions 12a and 13a are fixed in place in advance with tapping screws 37 and 37 before being shipped, but if necessary, when installation is carried out at the installation site, the parts may be closed. Of each of the above-mentioned shoji in the state, that is, the two outer shoji 17 and one inner shoji 18, the shoji that is restrained in the fitted shape, here the inner shoji 18 located at the center of the window frame 11. On the surface of at least one side stile 25,
This retaining member 31 is fitted and surrounded from the indoor side over its entire exposed length, and both ends in the longitudinal direction are connected to the extensions 12a and 13a of the upper frame 12 and lower frame 13, respectively. At the same time, the tapping screws 37, 37 may be screwed into the respective tapping screw holes 34, 34 from the side of each of these extensions 12a, 13a, and firmly attached at that position.

Here, in order to attach the longitudinal ends of the aforementioned retaining member 31 to the extensions 12a and 13a extending toward the indoor side from the upper frame 12 and lower frame 13 of the window frame 11, It is easiest to form the extensions 12a and 13a as flat as possible so that they can be directly attached to them, but the attachment in this embodiment will be described more specifically. While fitting the retaining member 31 onto the connecting frame 25, its lower end is inserted into the extending portion 1 of the lower frame 13.
The inner rising piece 13b rising from the upper frame 12 is inserted into the inner side of the inner rising piece 13b, and the upper end thereof is inserted into the extending part 1 of the upper frame 12.
Position it by pushing it into the bottom surface of 2a, and then
The tapping screws 37, 37 may be installed by screwing into the tapping screw holes 34, 34 in the same manner as described above, and with this configuration, the retaining member 31
The lower end portion of the retaining member 31 can be covered from the outside, which is convenient for disposing of condensed water flowing through the retaining member 31, and improves its appearance and appearance. Further, as the joining frame 25, a member having a cross-sectional shape as shown in FIG. By using a member with
1 and each side surface can be made to match in plan view, and the appearance etc. can be improved.

Therefore, in the case of the device structure of this embodiment, the retaining member is fitted over the entire length of the surface of the exposed stile of the inner shoji from the indoor side, and the inner shoji is fitted and closed. I made it to be restrained by
The inner shoji itself can be made impossible to open and close, but on the other hand, the connecting stile of the inner shoji itself is restrained only from the indoor side by a retaining member, and there is no restraint from the outdoor side. It can be removed. In this way, it is possible to remove the inner shoji that is restrained in the fitted shape in the same way as the outer shoji that can be opened and closed without removing the retaining members one by one. All the drawbacks due to the non-removability of the retaining member are eliminated, and since the retaining member itself has a smooth shape, the external appearance of the surface facing into the room is improved.

In the above embodiment, a case was described in which this device is applied to a sliding sash window in which the inner shoji located in the center of a three-panel shoji type is fitted and restrained. However, it can also be applied to a wide range of other sliding sash windows, and regarding the restraint part, it can be applied not only to the vertical stile on the center side of the window frame (common stile) but also to the vertical stile on the side that comes into contact with the window frame. Of course, there is no problem in applying it.

[Effect of idea]

As described in detail above, when using this invention, the cross section is approximately U-shaped, consisting of a surface portion and side portions bent at right angles from both ends of this surface portion, and tapping screw holes are provided at each inner corner. Using a retaining member provided with a retaining member, the retaining member is fitted and surrounded from the indoor side over the entire length exposed on the surface of the stile of the inner shoji that is to be restrained in a fitting shape, and both ends of the retaining member are fitted and surrounded. The inner shoji, which is restrained in the fit-in shape, can be removed to the outside of the room because the shoji is abutted against each extension of the upper frame and the lower frame of the window frame, and is attached to each tapping screw hole with a tapping screw. It can be useful for cleaning internal shoji screens and replacing glass, and it can also greatly improve the appearance of the fitting part, and has a simple device configuration and excellent workability. It has the following features.
