Description

[Detailed explanation of the idea] This invention relates to the upper stile of Satsushi shoji.

Satsushi shoji screens installed in buildings built in areas with strong seasonal winds are required to be strong enough to withstand wind pressure, and in order to meet this requirement, various efforts have been made to improve the structure of the stile. Ta.

However, conventionally, in order to reinforce the upper stile, as shown in FIG. 1, a structure was adopted in which the inner and outer vertical walls 1 and 2 were connected by two upper and lower flat webs 3 and 4.

If the shoji is of the type that slides by fitting the guide rail 5, which is mounted on the upper frame H of the window frame, into the groove 6 of the upper opening of the upper stile A, the depth of the groove 6 is The depth must be such that it allows the shoji door to be attached to and removed from the window frame in a gradual manner, and that it remains engaged with the guide rail 5 in the erected state.

Further, in order for the upper and lower webs 3 and 4 to exhibit a reinforcing effect, the lower web 4 must be appropriately spaced downward from the upper web 3.

Therefore, since the height of the conventional upper stile is inevitably large,
The drawback was that the window's lighting area became smaller.

Furthermore, since the groove 6 of the upper stile into which the guide rail fits has a width significantly larger than the wall thickness of the guide rail 5,
In order to prevent the upper stile from swinging laterally with respect to the guide rail, the guide rail was conventionally installed in the notch groove 8 formed at the upper end of the side of the door stop with the left and right vertical Ii7 with a width slightly larger than the wall thickness of the guide rail 5. 5 is fitted.

Therefore, when a strong wind pressure is applied to the shoji, the load on the guide rail 5. In order to concentrate on the contact point between the stile and the edge 9 of the door stop side surface forming the notch groove 8 of the stile, a part of the guide rail 5 or the edge 9 of the notch groove 8 is deformed, and the upper stile of the shoji or the side This design has the disadvantage that the shoji may vibrate or the sliding movement of the shoji may become slow. To provide a shoji upper stile that has sufficient wind pressure strength, does not cause deformation of guide rails, etc. due to wind pressure, and allows the height of the upper stile to be reduced, allowing for an expansion of the window lighting area. This is what I am trying to do.

Next, an embodiment of this invention will be described based on the drawings from FIG. 2 onwards.

The upper stile A1 according to this invention has both inner and outer vertical walls 11. 12 is combined with a reinforcing wall 13 having a roughly U-shaped cross section and a web 15 forming a glass fitting groove 14 together with the vertical wall.
．． A groove 16 is formed which extends from the inner side of the upper part of the upper frame 12 to the web 15 and into which the guide rail 5 of the upper frame H is fitted.

The lower part of the groove 16 has the same width as the notch groove 8 formed at the upper end of the door stop side of the vertical stile 7 and is fitted with the guide tray/L15, and has the shape of the bottom of both grooves. and the heights match.

When the shoji is installed on the window frame, the guide rail 5
The lower end portion is located at the lower portion 16a of the groove 16, and the lower end portion of the guide rail and the bottom portions of the grooves 8 and 16 are separated from each other by an amount that allows the shoji to be attached and detached.

In this way, when the shoji is erected, the lower end of the guide tray/L15 is located not only in the cutout groove 8 of the vertical stile 1, but also in the lower part of the groove 16 of the upper stile, which has the same shape and soft fit as this groove. 16a, so when the shoji is pushed indoors or outdoors perpendicular to the guide rail 5 due to a change in outside air pressure, the force of the shoji is applied to the entire length of the reinforcing wall 13 and the notch in the vertical stile. The edges forming the groove 8 also apply to the guide rail and the forces are distributed.

Therefore, neither the reinforcing wall 13 nor the stile edge 9 will be deformed, and since the bottom 16a of the groove 16 in the upper stile is rounded, it is not possible to tilt the shoji and remove it from the window frame. It's easy to do.

Furthermore, the reinforcing wall 13 has a U-shape, and the groove in which the guide rail is fitted has a depth that allows it to be attached and detached in a sliding manner, and the lower end of the groove is connected to the web 15, so that the upper The height of the stile A□, that is, the height from the upper end to the lower end of the vertical wall 11.12, depends on the depth of the groove 16 that can be raised and lowered when installing and removing the shoji, and the glass insert provided on the lower side of the web 15. The depth of the grooves 14 is approximately equal to the depth of the grooves 14 combined, and is significantly smaller than that used in conventional two-web applications.

In the embodiment shown in FIG. 2, the reinforcement 13 is connected to the web 15 at the central lower end of the wall, thereby forming part of the reinforcement wall, part of the web, and one vertical wall. Since the shoji is continuous in a triangular shape, when the shoji receives wind pressure and the stile is pressed against the guide rail, it is reinforced
is Gaitley.

The reinforcing wall is reinforced so that it does not dent due to the wall.

In FIG. 2, the web 15 and the reinforcing wall 13 are connected via a screw hole 17 for connecting the upper stile and the rail, but it goes without saying that the invention is not limited to this.

As shown in the fourth corner A2, the reinforcing wall 13 is directly attached to the web 1.
5, the screw hole 17 may be provided on the underside of the web 150. In the embodiment shown in FIGS. 2 and 4, the upper stile is connected to the groove 16.
Since the indoor part and the outdoor part are connected only by the reinforcing wall 13 or the web 15, centering on the vertical wall 1, when particularly strong wind pressure is applied, the connection part 7 is bent and the vertical wall
1 and 12 may become...

The embodiment shown in FIG. 5 has been improved to eliminate the above-mentioned drawbacks, and by slightly exposing the upper stile A3 reinforcing wall 13 and the web 15, the indoor side part of the upper stile 16 is and the outdoor side part are double-bonded and reinforced by a reinforcing wall and a web.

The bottom portion 13a of the reinforcing wall is formed into an arc shape, and
A circular arc 15a is also formed on the upper central surface of the web 15, and a screw hole 17 is formed by these arcs 15a.

In Figures 2 to 5, 18 is a groove provided inside the upper end of the vertical wall 11 or 12, into which the shoji contacts the guide rail 5 of the upper frame when the shoji is repeatedly pressed against the window frame. Attach the airtight material 19.

As mentioned above, this upper stile made by Koshiba has both internal and external vertical walls.
The upper stile is made up of a substantially U-shaped reinforcing wall that opens upwards and forms a groove into which the kiterail of the upper frame fits, and a web provided on the lower side of the reinforcing wall. It has sufficient strength against twisting, bending, etc.

In addition, since the reinforcing wall has a U-shape with 7 sides, the guide rail fitting groove and the glass fitting groove are close to each other, so that the height of the upper stile is higher than that of the conventional upper stile with two webs. The bottom of the window also becomes larger, allowing for a larger area of light to be let in by the window, while also simplifying the appearance of the upper part of the window.

Furthermore, the guide rail fitting groove formed by the reinforcing wall has a shape that matches the notch groove formed on the side surface of the vertical frame door, so that the lower part of the guide rail fitting groove that fits the lower end of the guide rail when the shoji is in the construction material state matches the notch groove formed on the side surface of the vertical frame door. The wind pressure received by the stile is dispersed and supported not only by the edge forming the notch groove of the stile, but also by the reinforcing wall forming the lower part of the groove of the upper stile. The section or guide rail will not be deformed by wind pressure.

Therefore, the upper part of the shoji does not sway or the airtightness is impaired.
