Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sliding device for shoji screens.

[Prior Art] Among windows used in buildings and the like, there are some windows in which a plurality of rotating glass screens are vertically arranged in parallel to a window frame.

In this type of shoji device, when a driving part (not shown) attached to the window frame a is manually or electrically operated as shown in FIG. Has become.

[Problems to be Solved by the Invention] The above-described rotary shoji device has a drawback that it is difficult to wipe and clean the glass of the shoji screen b. That is, the inner surface of the glass can be wiped from inside the room, but the outer surface of the glass cannot be wiped from inside the room when it is closed. In the case of windows, wiping from the outside is awkward and dangerous.

If the shoji screen b is fully opened as shown in FIG. 6, it is possible to wipe the outer surface of the glass from the inside of the room by reaching out between the upper and lower shoji screens, but the top shoji screen is the window frame a. Since it is impossible to reach from the gap between them, it is necessary to rotate the hand from the lower side of the shoji to the outer side of the glass to clean it, and the work is difficult, and the upper part of the glass cannot be reached and wiping is sufficient. There are many things that cannot be done.

The present invention has been made to solve such conventional inconveniences, and provides a sliding door sliding device capable of easily cleaning the glass outer surface of the uppermost sliding door from the indoor side with the sliding door fully opened. This is a technical issue.

[Means for Solving the Problem] As means for solving this problem, the present invention is a shoji device in which a shoji is attached to a window frame so as to be rotatable in the vertical direction, and is fixed to the window frame. An arm bracket, an engaging rivet projecting from the vertical frame of the shoji screen and an elongated hole formed in the longitudinal direction of the vertical frame, and a guide elongated hole that engages with the rivet and can slide the rivet. And a hinge provided with a rivet that engages with the long hole of the shoji and can slide along the long hole, and a mounting portion that is detachably fixed to the upper frame of the shoji, and one end of this hinge is pivoted. The gist of the present invention is to include an arm that is supported and whose other end is pivotally supported by the arm bracket.

[Operation] When cleaning, by opening the shoji screen fully and removing the screw on the attachment part of the top shoji screen, the top shoji screen can be slid downward along the long hole of the hinge. As a result, a space is formed between the upper frame of the window frame and the upper frame, and by using this space, the outer surface of the uppermost glass of the shoji screen can be wiped clean from the indoor side. Since the second and subsequent shoji screens can be wiped from the indoor side as usual, it is possible to wipe and clean them all from the indoor side.

After cleaning, the uppermost shoji screen can be slid upward and tightened and fixed with the screws to restore the original state.

Embodiment Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment.

In FIG. 1, reference numeral 1 denotes an arm bracket fixed to a vertical frame 2a of a window frame 2, which is an elongated hole 1a extending in the vertical direction and a curved elongated hole whose lower end portion is inclined downward toward the front side of the window frame. 1b
Are formed. Reference numeral 3 is an arm, and rivets 3a and 3b are provided on the lower end of the arm 3 to project the long hole 1 of the arm bracket 1.
It engages with a and 1b respectively, and the upper end is pivotally supported by the hinge 4 by the shaft 3c. In the hinge 4, a long hole 4a for sliding is formed in a substantially central portion, a curved locking portion 4b is formed at an upper end thereof, and a rivet 4c is further provided at a lower portion of the hinge 4. The projection 4 is provided with a mounting portion 4d for fixing the shoji screen on the top. The hinge 4 has its tip end pivotally supported by a shaft 4e on a connecting rod 5 provided in the vertical frame 2a of the window frame 2, and the mounting portion 4d is provided with the uppermost shoji 6 as shown in FIG. The upper frame 6a is fixed by a set screw 7 via a mounting piece 6b. The shoji 6 is provided with a rivet 6d for engagement on a side surface of a vertical frame 6c, and a guide hole 6e is formed below the rivet 6d. The rivet 6d is slidably engaged with the long hole 4a of the hinge 4. In addition, the rivet 4c of the hinge 4 is slidably engaged with the guide hole 6e while being engaged with the curved engaging portion 4b. A second shoji 8 and a third shoji 9 are rotatably attached to the window frame 2 via hinges as in the conventional case.

The shoji sliding device according to the present invention is constructed as described above, and when the driving part (not shown) is operated manually or electrically to move the connecting rod 5 up and down, three shoji 6,8,
It can be opened and closed by rotating 9 at the same time in the vertical direction.

When cleaning the outer surface of the glass of the shoji screen, when the shoji screen is fully opened and the setscrew 7 is removed, the top shoji screen 6 becomes free with respect to the hinge 4.
The rivet by moving it up a little along the hinge 4.
6d is disengaged from the engaging curved portion 4b of the long hole 4a, and when the shoji 6 is pushed slightly forward, the rivet 6d slides along the long hole 4a, and the shoji 6 slides downward as shown in FIG. To be made.
When sliding the shoji 6, the rivet 4c of the hinge 4 slides along the guide hole 6e of the shoji 6, and when the rivet 6d of the shoji 6 comes into contact with the lower end edge of the long hole 4a, the guide hole 6e. Of the sliding door 6 is abutted against the upper edge of the sliding door 6, so that the sliding door 6 is stopped at the same time and stably held at that position.

In this way, when the uppermost shoji 6 is slid downward, a gap 10 is formed between the upper frame 6a and the upper frame 2b of the window frame 2 so that the arm can be inserted therein. As shown in the figure, the arm can be pulled out from the indoor side and the outer surface of the glass of the shoji screen 6 can be wiped clean. The second and third shoji,
9 can be easily wiped and cleaned from the inside of the room as usual. Therefore, the outer surface of the glass of each shoji can be easily wiped and cleaned from the indoor side.

After this wiping and cleaning, the shoji screen 6 is slid along the long hole 4a of the hinge 4, the rivet 6d is brought into contact with and received by the locking curved portion 4b, and the attachment piece 6b is attached to the attachment portion of the hinge 4 by the set screw 7.
The screens 6 can be returned to their original positions by tightening and fixing them to 4d, and then the screens can be closed at the same time by raising the connecting rod 5.

In addition, in the above-described embodiment, an example in which a plurality of rotary shoji is arranged is shown, but the present invention is not limited to this and the present invention can be applied to the case where there is one rotary shoji.

[Advantage of the Invention] According to the present invention described above, the rotary shoji is constructed so that it can be slid downward in the fully opened state. Therefore, the arm is inserted between the upper frame of the shoji and the upper frame of the window frame. It is possible to provide a gap, and by using this gap, the outer surface of the glass of the shoji screen can be wiped clean from the indoor side, and its practical effect is extremely large.
