Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding screen door that can cover the entire surface of a sash and can also be opened on one side.

In most conventional screen doors, a shoji of about half the length of the sash is attached to a pair of upper and lower rails and a guide part that are integrated with or attached to the sash frame, and the shoji is moved along the rails and guide part. However, it did not cover the entire surface of Satsushi.
For this reason, even if only one side of the glass door could be opened while the screen door was in use, it was not suitable for opening both the left and right sides at the same time, and there was no room to install a shoji screen other than the screen door to shade the sun.

In other words, in order to cover the entire surface of the sash and make it movable, a rail and a guide section were required to attach another shoji, but using such a method would complicate the structure of the sash frame and increase the processing time. However, this method has such disadvantages and is difficult to implement.

In order to eliminate the above-mentioned conventional disadvantages, the present invention relates to a screen door in which the inner and outer shoji can be moved in a sliding manner without providing a special rail or guide part on the sash frame. Movement is the same as before, but the outer shoji is movable in that one side follows the rail protruding from the outer surface of the lower stile of the inner shoji, and the other side uses the same rail as the inner shoji. .

That is, in the present invention, the door rollers attached to the left and right lower ends of the inner sash are mounted on the upper surface of the inner shoji rails protruding from the outer end of the lower frame of the sash, and the outer sash is mounted on the outer rails protruding from the outer surface of the lower frame of the inner sash. A door roller attached to one side of the lower end is mounted, and a door roller protruding from the inner surface of the other side of the lower stile of the outer shoji is mounted on the upper surface of the inner shoji rail, and the upper end of the inner and outer shoji is placed on the guide rail of the upper frame of the sash. This is what was charged.

Next, the present invention will be explained based on the drawings. An inner shoji rail 2 is provided protruding from the outer end of the sash lower frame 1, and door rollers 4, 4 attached to the left and right lower ends of the inner shoji 3 are mounted on the upper surface of the rail. At the same time, an upward hook-shaped outer rail 5 is integrally provided on the outer surface of the lower stile 3a of the inner shoji screen. A door wheel 7 is built into one side of the lower stile 6a at the lower end of the outer shoji 6 (on the right side in the figure, closer to the inner shoji). A fitting 8 is fixed to the inner surface of the left side lower stile 6a, and a door wheel 9 pivotally supported on the inner surface of the fitting is mounted on the upper surface of the inner sash rail 2. Thus, the upper end of the upper stile 3b of the inner shoji 3 is inserted into the guide rail 11 of the sash upper frame 10, and the upper stile 6b of the outer shoji 6 is provided with an upward hook-shaped plate 12 protruding from the upper stile 6b. Internal shoji 3
Insert it into the guide rail 11 parallel to the upper end of the.
In the figure, S is a stopper protruding from the inner surface of the vertical stile 6c on the other side of the outer shoji.

If the entire surface of the sash is currently covered by the inner and outer shoji 3 and 6 (see Figure 1), the outer shoji 6
One side (right side in the figure) is on the outside of the other side of the inner shoji 3 (left side in the figure), and the other side of the outer shoji 6 is on the door roller 9.
It is mounted on the inner shoji rail 2 by means of the following. From this state, when the outer shoji 6 is opened toward the inner shoji 3 side, the door roller 7 built into the lower end of one side of the outer shoji is moved by the outer rail 5 protruding from the outer surface of the lower stile 3a of the inner shoji.
Since the door roller 9 slides on the inner shoji rail 2 at the other end of the outer shoji, the outer shoji is finally positioned on the outer surface of the inner shoji and one side of the screen door is opened.

In addition, in order to fully overlap the outer shoji 6 with the inner shoji 3, the other side door wheel 9 of the outer shoji will be positioned at the lower end of the inner shoji.
Cut out part of a. When the outer shoji 6 is opened toward the inner shoji 3, the hook-shaped plate 12 protruding from the upper stile 6b of the outer shoji moves within the guide rail 11, and the outer shoji opens toward the inner shoji. When fully opened, the side edge of the inner shoji 3 comes into contact with the stopper S of the vertical stile 6c on the other side of the outer shoji, suppressing the movement of the inner and outer shoji from side to side.

FIG. 3 shows another embodiment of a door roller attached to one side of an outer shoji.
(a) It is exposed on the inner surface and is pivoted,
By doing so, the width of the outer rail 5 of the inner shoji can be narrowed.

FIG. 4 shows another embodiment of the outer shoji upper stile fitted to the guide rail, in this case, the inner end protrusion T of the hook piece K fixed to the inner surface of the other side of the outer shoji upper stile 6b is fitted into the guide rail 11, and the outer shoji 6
A groove piece M fixed to one side of the inner shoji upper stile 3b is attached to a downward hook-shaped guide G protruding from the outer surface of the inner shoji upper stile 3b. The groove piece M is guided by the guide G of the inner shoji and moves within the guide rail 11.
By doing this, the movement of the outer shoji 6 is stabilized.

As explained above, in the present invention, two shoji are installed in a sliding manner, so the entire surface of the sash can be covered by the inner and outer shoji, and if one shoji is opened, only one side of the sash can be covered. The advantage is that it can be done conveniently, and it can be done without requiring large-scale machining, as it is only necessary to attach one rail each to the upper and lower frames as in the conventional case. It is also possible to install a shelter or the like in place of or together with a screen door, which has a remarkable effect of being used for multiple purposes.
