In the figure, the inner shoji 2 has an upper stile 4, a lower stile 5, a vertical stile 6, and a matching stile 7 assembled in four directions, and a glass 8 is held by each stile. The outer shoji 3 has the same structure as the inner shoji, with an upper stile 9, a lower stile 10, a vertical stile 11, and a combined stile 12 to form glass 13.
is retained.

2 is an enlarged sectional view taken along the line AA in FIG. 1, and FIG. 3 is an enlarged sectional view taken along the line BB in FIG.

As shown in FIG. 2, the connecting frame 7 includes a side member 14 on the outside of the shoji in the inside and outside directions, an outside member 15 on the outside,
Inner member 16 on the indoor side, bottom member 1 of glass groove 17
8 is made into a hollow shape with a square cross section and used as a base material, and an L-shaped protrusion 2 is provided inside the base material so as to guide the pulling tool 19.
1. A group of guide ridges 23 is provided to rub against the ridges 22 and the puller 19 and reduce the frictional force between the puller 19 and the stile 7. On the outside of this base material, an outer member 15 is provided so as to form a glass groove 17;
The inner member 16 is elongated, and L-shaped protrusions 25 for attaching a glazing channel bead 24 are formed on opposite ends thereof. A smoke return 27 that engages with a smoke return 26 provided on the joining frame 12 of the outer shoji 3 is provided on the outside of the base material, and a smoke return 27 that engages with a smoke return 26 provided on the frame 12 of the outer shoji 3 is provided on the inside of the base material, and a second Two rectangular tubular bodies are formed and serve as reinforcing members 28 of the stile. A groove is provided in the indoor side member of the connecting frame 12 of the outer shoji 3, and airtight packings 31 and 32 that contact the connecting frame 7 of the inner shoji 2 are fitted into the groove.

4 is provided. As shown in FIG.
It is necessary to prevent interference when the structural members at the end of the second projecting ridge 37 hanging further outward, the airtight material 38, and the inner shoji 2 are hung and fitted into the opening frame 1.

A pair of L-shaped protrusions 4 are attached to the protrusions 37 so as to form grooves 39 into which the airtight material 38 is fitted on the outside.
1 and 42, and a pulling protrusion 43 on which the cam portion 33 of the pulling tool 19 slides is provided inside the lower protrusion 42.

The airtight material 38 has a stepped shape on the outside, and an airtight surface 38b for the upper part of the outer shoji is provided at a position continuing from below the protrusion 38a toward the inside.
Continuing downward from 8b and retreating further inward, an airtight surface 38c for the upper part of the inner shoji is provided. The airtight surface 38b for the upper part of the outer shoji is in contact with an airtight packing 40 provided on the upper stile 9 of the outer shoji 3. The inner surface of the upper part of the outer member 45 of the upper stile 4 of the inner shoji and the outer member 15 of the joining stile 7 of the inner shoji comes into contact with the airtight surface 38c for the inner shoji. Airtight material 3
8 and the airtight gasket 40, the outer member 45 of the upper stile, and the upper part of the connecting stile 7 are brought into contact with the cam portion 33 of the pulling tool 19 when the pulling tool 19 is pushed up to the rising end as shown in the figure. The matching stile 7 of the inner shoji is moved inward by the ridge 43, and the outer member 45 of the upper stile 4 of the inner shoji and the outer member 15 of the matching stile 7 are moved inward.
This is done by moving the upper part of the outer shoji 3 inward through the smoke return panels 26 and 27, thereby drawing the airtight packing 40 inward.

When the side member 14 of the stile 7 and the bottom member 18 hang the inner shoji 2, the inner end of the protrusion 43, the protrusion 38a of the airtight material 38, and the airtight surfaces 38b, 3
The shape of the cutout 34 is determined so as not to interfere with the cutout 8c.

The notch 34 is such that the distance between the inner surface of the outer member 15 of the connecting frame 7 and the opposing circumferential surface 44 of the notch is equal to the horizontal distance between the protrusion 38a of the airtight material and the inner end of the pulling protrusion 43. Continuing from the outer member 15 at the upper end of the connecting frame 7, a step-shaped circumferential surface 46 is provided on the side member 14 and the bottom member 18, and the circumferential surface 44,
46 is made larger than the horizontal distance between the airtight surface 38b of the airtight material 38 and the inner side end of the pulling protrusion 43. The depth of the notch 34 is determined by the depth of the inner shoji 2 from the opening frame 1.
There are as many cutouts as necessary to hang and assemble the
The bottom 29 of the upper stile 4 is located at a position that substantially coincides with the upper surface of the bottom member 47 of the glass groove 17a that connects the inner and outer members of the upper stile 4.

The upper part of the reinforcing member 28 of the joining frame 7 is cut off for hanging. For safety reasons, the lower part of the reinforcing member 28 is often cut off to prevent the ankle from being caught between the reinforcing member 28 and the floor surface.

As shown in FIG. 5, the protrusion 25 constituting the glass groove 17 is removed from the upper part of the stile 7, and the upper part of the square-shaped portion of the outer member 45 at one end of the upper stile 4 shown in FIG. 3 is removed. Then, insert the upper stile 4 into the end of the joining stile 7 so that the 4th end of the upper stile contacts the bottom member 18, and insert the hole 48 in the side member 14 of the joining stile 7, which is larger than the head of a tapping screw (not shown). The tapping screw passes through the hole 49 in the bottom member of the connecting frame and is screwed into the tapping hole 50 (FIG. 3) in the upper frame 4.

When a sliding sash like the one described above receives wind pressure (negative pressure), the inner shoji 2 receives a force directed toward the outside, and the upper end of the sliding stile 7 receives a force directed from the inside toward the outside. The force is carried by the pulling protrusion 43 at the upper part of the joining frame 7 via the pulling tool 19. The part that receives such wind pressure (negative pressure) is concentrated at the upper part of the connecting stile 7 (the upper stile 4 does not bear this force), and the cross section of this part is shown by the cross section line in Fig. 2. Although there is a remaining member 18a cut into the bottom member 18, an L-shaped guide protrusion 21, and a remaining member 14a cut into the side member 14 as shown in FIG. ,
Reinforcement member 28, glazing channel bead 2
There is no protrusion 25 for locking the frame 4, and the section modulus is much smaller than that of the middle part of the connecting frame 7, and the bending strength to withstand the negative pressure of the wind force is weak. For this reason, combined with the recent tendency to make the openings larger, there is a growing risk that the upper part of the mating part of the inner shoji will be permanently deformed or damaged due to negative wind pressure. .

The upper end of the joining member of the inner sliding sash, which is configured to have a single sliding shoji on the inside and be removed inward, is also the same as the joining stile 7 of the inner sliding sash of the double sliding sash described above. It has a similar structure and is subject to the same wind pressure, and it lacks the strength to withstand wind pressure in the same way as the interlocking frames of sliding sash screens.

Although the explanation is omitted, the lower part of the sliding frame 7 of the inner shoji has a similar structure, and a notch is provided from the lower part to the upper part to avoid interference with the rail of the lower frame of the opening frame 1. There is. Therefore, it has the same problem of lack of strength as the upper part of the stile.

Note that the upper and lower ends of the matching stile of the outer shoji of the sliding sash have the same structure as the upper and lower ends of the matching stile of the inner shoji.
Therefore, the strength of the upper and lower edges of the outer shoji frames is weak. This part receives a concentrated load when resisting the positive wind pressure, and even if the upper and lower frames share this load, there is a problem that the strength is similarly weak.

This invention is based on the structure of the end of the mating part of sliding sashes and single-sliding sashes, especially the internal shoji of sliding sashes,
An object of the present invention is to provide a structure for an upper end of a mating part that does not deform or break against wind pressure in an internally moving single-pull sash.

This invention has a hollow part with a rectangular cross-section, one side of the hollow part connecting the inner and outer members forms the bottom member of the glass groove, and the upper and lower ends have notches through which the shoji guide members of the upper and lower frames are inserted. An end of a horizontal stile perpendicular to the provided joining stile contacts the bottom member of the joining stile, and is fixed by inserting a small screw hole in the bottom member and screwing a tapping screw into the tapping hole of the horizontal stile. In this connecting section end structure, reinforcing tools are provided at the upper and lower ends of the connecting stile, and the reinforcing tools are plate-like members, and each plate surface abuts against the connecting stile within the hollow section of the connecting stile, and the reinforcing tools are plate-like members. A first portion of the bottom member of the glass groove of the laminated stile where the plate surface contacts the surface opposite to the bottom surface of the glass groove, and a second portion which is bent from at least the said portion and where the inner member of the laminated stile contacts the plate surface. , the circumferential end of the second part bent from the part that contacts the bottom member is provided with an L-shaped protrusion in the hollow member of the joining stile, and is fitted with the protrusion, and the reinforcing tool One side extends toward the middle of the connecting stile beyond the position corresponding to the tapping hole of the horizontal stile used to connect the horizontal stile and the connecting stile, and the other end surface extends toward the bottom of the end notch of the connecting stile.
