Thereby, when the arm member 30 rotates, the bottom portion of the recessed portion 37 does not come into contact with the upper surface 12 a of the lower frame 12.

As shown in FIG. 4, the engagement pin 41 has a flange 41a.
The flange 41a is larger than the width of the long hole 31 described above and smaller than the width of the one end portion 31a of the plane C shape, and the engaging pin 41 is inserted into the long hole 31 from the one end portion 31a. , Get out.
The operation tool 42 includes an L-shaped plate 43, a reinforcing plate 44 fixed to one piece 43a of the plate 43, and an operation knob 45 attached to the other piece 43b of the plate 43. The engaging pin 41 is attached to 43a and the reinforcing plate 44. The operation knob 45 is attached with a screw 45a, but is not limited thereto.

The switching member 40 includes a mounting plate 46 and a presser plate 47.
The mounting plate 46 has a substantially U-shape in which the longitudinal intermediate piece 46a is positioned below the longitudinal side pieces 46b, and an opening 46c through which the engagement pin 41 is movably inserted is provided in the intermediate piece 46a. An attachment hole 46d is formed in both side pieces 46b.
The pressing plate 47 is fitted and attached to the upper surface of the mounting plate 46 to form a gap with the longitudinal intermediate piece 46a, and the engaging pin 41 is located at the longitudinal intermediate portion of the pressing plate 47. It has the opening part 47a penetrated so that movement is possible, and the elastic part 47b which hold | maintains this engagement pin 41 in a both-sides position.
Mounting holes 47c are formed on both sides of the pressing plate 47 in the longitudinal direction.

One piece 43a of the plate 43 and the reinforcing plate 44 are slidably provided along a gap between the mounting plate 46 and the presser plate 47, and the engaging pin 41 is downward from the openings 47a and 46c. It protrudes.
Then, the mounting plate 46 and the presser plate 47 are fixed to the lower surface 22a of the lower collar 22 with a fixing tool, the engaging pin 41 is directed downward, and the operation knob 45 is directed to the indoor side. Then, the operation tool 42 is supported so as to be movable in the longitudinal direction of the lower rod 22, and the engagement pin 41 moves to the first position and the second position.
That is, the mounting plate 46 and the holding plate 47 are used to support the engaging pin 41 and the operating tool 42 so as to be movable to the first and second positions, and the mounting pin 41 and the operating tool 42 are mounted to the lower rod 22. A member is formed.

Therefore, when the operation knob 45 is set to the right position shown by the solid line in FIG. 1, the engaging pin 41 is set to the first position as shown in FIG.
When the shoji 20 is opened in this state, the arm member 30 rotates toward the outdoor side, and the engaging pin 41 contacts the end of the elongated hole 31 as shown in FIG. Become.

As shown by the phantom line in FIG. 1, when the operation knob 45 is moved to the left position, the engaging pin 41 comes out of the one end 31a of the elongated hole 31 and is positioned in the recessed portion 37 as shown in FIG. Second position.
When the shoji 20 is opened in this state, the engagement pin 41 moves to the outdoor side and the arm member 30 does not rotate. Therefore, the shoji 20 can be opened to the fully open state.

Thus, when the shoji 20 is opened to the fully open state, if there is a possibility that the arm member 30 may turn to the outside of the room due to vibration or the like, the arm member 30 will not turn to the outside of the room due to vibration or the like. It is preferable to provide means for releasing the holding and allowing the arm member 30 to rotate outwardly when a strong rotational force is applied.
For example, as shown in FIG. 3, a protrusion 33a is provided on the support shaft 33, a hole 30a is formed at one end in the longitudinal direction of the arm member 30, and the arm member 30 is connected to the lower frame 12 as shown in FIG. When substantially parallel (that is, when the shoji 20 is in a closed state), the coil spring 39 causes the hole 30a to fit into the protrusion 33a, and the arm member 30 is held so as not to rotate outward due to vibration or the like.
When the shoji 20 is opened with the engaging pin 41 as the first position, strong turning force acts on the arm member 30, so that the arm member 30 moves downward against the coil spring 39, and the hole 30a projects. The arm member 30 is released from the portion 33a to release the holding, and the arm member 30 is rotated outward as shown in FIG.

As shown in FIGS. 1 and 2, the operation knob 45 moves along the indoor side surface 22b of the lower rod 22, and the operation knob 45 can be visually observed from the room.
On the indoor side surface of the lower eyelid 22 is provided a display unit 3 for displaying the shoji open state according to the position of the operation knob 45 (operation tool 42).
For example, as shown in FIG. 8, a half-open display 3a for displaying a half-open character and a design and a full-open display 3b for displaying a full-open character and a design are provided. When the engagement pin 41 is in the first position, the operation knob 45 approaches the half-open display 3a, and the operation pin 45 is in the left position as shown in FIG. 8B. In the case of the second position, the operation knob 45 approaches the fully open display 3b.

Since it is like this, the open state of the shoji 20 can be confirmed by visually observing the operation knob 45 and the display unit 3.
In addition, since the operation tool is located on the display unit and the switching state of the operation tool can be always checked even when the shoji is opened, the operation is performed when the shoji is opened with the slider as the second position. Even if the slider moves due to an erroneous operation of the tool, it is easy to notice the movement of the slider due to the erroneous operation. Therefore, it is difficult for the slider to hit the side surface of the arm member or the like and to be damaged by closing the shoji as it is without noticing the movement of the slider due to an erroneous operation or the like.

In this embodiment, an auxiliary lock 4 is attached.
The auxiliary lock 4 includes a lock receiver 5 attached to the upper surface of the lower frame 12, and a lock body 6 attached to the lower collar 22. The lock body 6 is the same as the switching member 40 described above as shown in FIG. .
The lock receiver 5 has a groove 5a into which the engagement pin 41 is inserted and removed.

Then, when the engagement pin 41 is moved by the operation knob 45 to a position where it is pulled out from the groove 5a as shown in FIG.
Further, when the engagement pin 41 is moved by the operation knob 45 to a position where it is inserted into the groove 5a as shown in FIG.

Next, a second embodiment of the present invention will be described.
This embodiment differs from the above-described embodiment in that the shoji 20 can be locked by the arm member 30 and the switching member 40 described above, and the other is the same.
As shown in FIGS. 11 and 12, the lock portion 50 is provided on the attachment base portion 32, and the engagement pin 41 can move to a lock position where the lock pin 50 interferes with the lock portion 50 and cannot move to the outdoor side when the shoji 20 is closed. Like that.
For example, an elongated locking hole 51 is formed closer to one end than the recessed portion 37 in the arm member 30, and the engaging pin 41 can be inserted into and removed from the elongated locking hole 51.

The engaging pin 41 is inserted into the locking slot 51 as shown in FIG. 11 by moving the engaging pin 41 with the operating tool 42, that is, the operating knob 45, with the shoji 20 closed.
As a result, the engagement pin 41 is positioned opposite to the indoor side of the lock portion 50, so that when the shoji 20 is to be opened, the engagement pin 41 interferes with the lock portion 50 and cannot move to the outdoor side. Therefore, the shoji 20 can be locked.

  Further, if the engaging pin 41 is extracted from the locking elongated hole 51, the engaging pin 41 is moved away from the lock portion 50 in the in-plane direction, so that the engaging pin 41 can move to the outdoor side. The shoji can be opened as in the embodiment.
