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. The movement of the outer shoji is the same as before, but the outer shoji is movable on one side along a rail protruding from the outer surface of the upper stile of the inner shoji, and on the other side uses the same rail as the lower end of the inner shoji. It is.

That is, in the present invention, the door rollers attached to the left and right lower ends of the inner shoji are mounted on the upper surface of the inner shoji rails that protrude from the outer end of the sash lower frame, and the upper end of the inner shoji is mounted within the guide rails that are vertically installed on the outer edge of the sash upper frame. Along with charging,
A door roller attached to the upper end of one side of the outer shoji is mounted on the outer rail protruding from the outer surface of the upper stile of the inner shoji, 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. It is something that

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 built in on the left and right sides of the lower stile 3a of the inner sash 3 are installed on the upper surface of the rail. The upper stile 3 of the inner shoji 3 is mounted on a guide rail 7 which is suspended from the outer end of the sash upper frame 6.
b Insert the top end. An upward hook-shaped outer rail 5 projects from the outer surface of the upper stile 3b, and a door wheel 9 is pivotally supported on the outer surface of one side of the upper stile 8a of the outer shoji 8 on the outer rail.
is mounted on the inner surface of the other side of the lower stile 8b of the outer shoji 8, and a fitting 10 is fixed with screws P to the inner surface of the other side of the lower stile 8b of the outer shoji 8. A door roller 11, which is pivotally supported on the inner surface of the fitting, is mounted on the upper surface of the inner shoji rail 2. It is mounted on a rack, and S in the figure is a stopper protruding from the inner surface of the vertical stile 8c 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 8 (see Figure 1), the outer shoji 8
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 8 is on the outside of the door roller 1.
1 is mounted on the inner shoji rail 2. When the outer shoji 8 is opened toward the inner shoji 3 side from this state, the door wheel 9 pivotally supported at the upper end of one side of the outer shoji slides on the outer rail 5 protruding from the outer surface of the upper stile 3b of the inner shoji. The other end of the outer shoji is connected to the inner shoji rail 2 by a door wheel 11 which is pivotally supported on the lower stile 8b via a fitting 10.
In order to slide on the screen, the outer shoji 8 is finally located on the outer surface of the inner shoji 3, and one side of the screen door is opened.

In addition, in order to fully overlap the outer shoji 8 with the inner shoji 3, the other side door wheel 11 of the outer shoji will be located at the lower end of the inner shoji, so in this case, a part of the lower stile 3a of the inner shoji should be cut out. . However, when the outer shoji is opened all the way to the inner shoji side, the other side vertical stile of the outer shoji 8
The side ends of the inner and outer shoji 3 come into contact with the stopper S of c, and the movement of the inner and outer shoji to the left and right is restrained.

Figure 3 shows another embodiment of the door roller attached to one side of the outer shoji, in which the outer rail 5 on the outer surface of the inner shoji
The upper door wheel 9 of the outer shoji mounted on the shoji is built into the upper stile 8a of the outer shoji, and by doing so, the distance between the inner and outer shoji 3 and 8 can be narrowed.

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. It is convenient, and the fact that 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.
