Description

[Detailed description of the invention] This invention relates to a shoji screen that uses metal shapes as frame materials.

To assemble a rectangular stile for a shoji using metal shapes, usually horizontal stile insertion holes are formed that open opposite the upper and lower ends of the vertical stile, and the insertion holes are inserted in the longitudinal direction of the horizontal stile. After fitting the ends, a tapping screw is passed through the doorstop side of the vertical stile and screwed into a screw hole provided in the horizontal stile to connect the vertical stile and the horizontal stile.

However, as shown in FIGS. 1 and 2 for a vertical stile and a lower stile, the conventional stile assembly of a shoji shoji consists of a pair of projecting edges 3a forming a glass fitting groove 2 of a vertical stile 1. , 3b is cut into an elongated rectangle, and if the vertical stile has an intermediate web, the longitudinal end of the intermediate web is also cut into a rectangle having the same shape as the cut portion of the flange. , a rectangular horizontal stile insertion opening 4 is formed, and a longitudinal end of a horizontal stile 5 having the same cross-sectional contour shape as the rectangular shape of the insertion opening is inserted into the insertion opening 4 in a direction perpendicular to the vertical stile. screw 8 into the screw hole 6 of the lower stile from the door stop side of the vertical stile.

However, there is a limit to the processing accuracy when forming the insertion opening 4 by notching the edges 3a and 3b of the vertical stile using a milling machine, etc., and the mold for forming the horizontal stile has manufacturing tolerances. Due to reasons such as errors in the extrusion molding dimensions of the stile, it is inevitable that the lower stile 5
It is inevitable that a minute gap 9 will be created between the inner or outer walls 7a, 7b and the inner surface of the insertion port. Therefore, there is a drawback that rain-mixed wind that enters the rail fitting groove 10 of the lower stile 5 from outdoors blows into the indoor space through the minute gap 9, and rainwater enters the house as droplets, and the minute gap itself However, it also had the disadvantage of spoiling the appearance of the stile connections of the shoji.

This idea was made in view of the above points, and the horizontal stile insertion opening of the vertical stile is formed into a trapezoid with the bottom bottom on the end side in the longitudinal direction of the vertical stile, and the cross-sectional shape of the horizontal stile is also shaped as described above. By making the trapezoid the same shape as the insertion opening, the horizontal stile can be tightly inserted and connected to the vertical stile insertion opening without being affected by the machining accuracy of the insertion opening or the error in the extrusion molding dimensions of the horizontal stile. can, and also,
To provide a shoji screen that can completely prevent rainwater from entering from a joint between a horizontal stile and a vertical stile.

Next, an embodiment of this invention will be described based on the drawings from FIG. 3 onwards. The vertical stile 11 is the same as a conventional vertical stile except for the shape of the horizontal stile insertion opening 14, which will be described later. The horizontal frame insertion opening 14 has a pair of projecting edges 13a, 13 forming the glass insertion groove 12.
b is cut out at the longitudinal end of the stile so that it gradually becomes narrower toward the longitudinal center of the stile, and if the stile has an intermediate web, the longitudinal end of the intermediate web. The parts are cut into the same trapezoid. Further, the horizontal stile 15 is formed to have the same trapezoidal cross section as the horizontal stile insertion opening 14.

When joining vertical stile 11 and horizontal stile 15, use horizontal stile 15.
Insert the longitudinal end of the trapezoid by moving it longitudinally toward the center of the stile (ie, in the direction of arrow A in FIG. 3), with the top base of the trapezoid first. Inner and outer sides 14a and 14b of the insertion port 14 and both inner and outer walls 17 of the horizontal stile
Since a and 17b are inclined with the same inclination angle, even if the notch processing accuracy of the insertion port 14 is low to some extent, or even if there is an error in the extrusion molding dimension of the side stile, the above-mentioned inclination angle is maintained. As long as the stile can be tightly fitted into the stile spigot 14 as shown in FIG. 4, the stile inner and outer walls 17a,
A minute gap is not generated between the outer surface of the 17b and the inner and outer sides of the insertion port 14.

The side stile 15 has an inner wall 1 as illustrated in FIG.
7a or the tip of the outer wall 17b has an airtight material fitting groove 2.
It is possible to add other elements such as 1.

Figures 3 to 5 show an example where the horizontal stile is the lower stile, but this idea can be applied to the upper stile as well, and the joint between the vertical stile and the upper stile is It is almost vertically symmetrical to the lower stile.

As mentioned above, there is no minute gap at the joint between the vertical stile and the horizontal stile, so in the lower stile, the groove 20 opens downward, and when applied to the upper stile, the groove 20 opens upward in the upper stile. Even if high-pressure air mixed with rain enters, rainwater will not splash into the room from the joint, and the appearance of the joint will not be damaged by minute gaps.

As described above, according to this invention, the pair of projecting edges forming the glass fitting groove at least at the lower end of the vertical stile are cut out so as to gradually narrow toward the center from the longitudinal end surface of the vertical stile, A trapezoidal horizontal stile insertion opening is formed between the cut surfaces, the horizontal stile is formed to have a trapezoidal cross section corresponding to the horizontal stile insertion opening of the vertical stile, and the longitudinal end of the horizontal stile is connected to the vertical stile. Because it fits into the horizontal stile insertion hole of the stile and connects both stiles, there is no minute gap between the vertical stile and the horizontal stile, so high-pressure air mixed with rain cannot enter into the grooves of the horizontal stile. Even if the stile and the vertical stile are connected, rainwater is prevented from splashing into the room from the joint between the horizontal stile and the vertical stile, and the appearance of the joint is not spoiled by minute gaps.
