Then, the crescent 10 is provided on the summoning candy 91 of the inner shoji 4a, and the receiving metal fitting 15 is provided on the summoning candy 91 of the outer shoji 4b.

  The crescent 10 includes a box portion 11 fixed to the summoning bowl 91, a handle 13 rotatably attached to the box portion 11, and a claw-shaped hook portion 12 fixed to the handle 13 and rotated together. ing. The receiving bracket 15 includes a receiving portion 16 that is engaged when the hanging portion 12 of the crescent 10 is rotated in a state in which the inner and outer obstacles 4a and 4b are closed.

  In FIG. 2, the front view which looked at the crescent 10 from the outdoor side is shown. As shown in this figure, the box portion 11 is formed in a box shape that is long in the vertical direction, and the handle 13 is provided so as to be rotatable adjacent to the box portion 11. The hanging portion 12 is attached to a surface that becomes an outdoor surface when the handle 13 is disposed upward.

  Inside the box part 11, a turning mechanism for turning the handle 13 and a turning restricting mechanism 20 for locking the turning of the handle 13 when the hanging part 12 is in the hung state are housed. Further, as shown in FIG. 3, two openings 11 a are provided on the outdoor surface of the box portion 11 for the trigger portion 23, which is a part of the rotation restricting mechanism 20, to protrude as the handle 13 rotates. It has been. In this embodiment, the trigger part 23 protrudes from the upper opening part 11a. Details of the rotation restricting mechanism 20 will be described later.

  In FIG. 3, the front view which looked at the metal fitting 15 from the room inner side is shown. 3, the right half shown in FIG. 3 is formed as a fixing portion 17 for the summing bowl 91, and the left half is formed as a receiving portion 16 for the hanging portion 12 of the crescent 10. The receiving portion 16 is formed in a frame shape having a square shape and a hollow central portion, and has an engaged portion 16 a that engages with the hanging portion 12 of the crescent 10 at the left end portion. A metal cover 30 made of a resin material is provided on the interior surface of the receiving portion 16.

  The metal cover 30 is formed in a frame shape having a hollow center part so as to substantially cover the receiving part 16. However, the engaged portion 16a is exposed to the indoor side. Further, the metal fitting cover 30 is formed with a protruding portion 31 that protrudes in a substantially L shape from the upper portion thereof to the side portion that faces the engaged portion 16a through a hollow portion, and further has a vertically symmetrical shape. Similarly, the protrusion 31 is also formed in the lower part. As a result, the metal fitting cover 30 is formed with the protruding portion 31 at a position outside the engaging direction 16a of the receiving portion 16 in the direction of finding. Further, the protrusion 31 is located at a horizontal position above and below the engaged portion 16a.

  FIG. 4 is a cross-sectional view of the summoning rods 91 and 91 in a state where the inner and outer children 4a and 4b are closed, and shows a state where the crescent 10 is not locked. As shown in this figure, in this state, the handle 13 of the crescent 10 is disposed downward, and the hanging portion 12 is disposed on the indoor side. The engaged portion 16a formed on the receiving portion 16 of the external obstacle 4b is disposed at a position facing the hook 12 of the crescent 10 with the internal obstacle 4a and the external obstacle 4b closed. Further, the protruding portion 31 formed on the metal cover 30 is disposed at a position facing the box portion 11 of the crescent 10.

  FIG. 5 shows a state in which the crescent 10 is locked from the state of FIG. As shown in this figure, in this state, the handle 13 of the crescent 10 is disposed upward, and the hanging portion 12 is engaged with the engaged portion 16 a of the receiving portion 16. Here, from the box part 11 of the crescent 10, the trigger part 23 of the rotation restricting mechanism 20 provided therein protrudes, and the tip part 23a abuts against the tip part 31a of the projection part 31 of the metal cover 30. .

  Thus, in the state in which the hook 12 of the crescent 10 can be engaged with the engaged portion 16a of the receiving portion 16 in a state in which the inner shroud 4a and the outer obstacle 4b are completely closed, the handle 13 of the crescent 10 The trigger part 23 which protrudes toward the outdoor side from the box part 11 with rotation is brought into contact with the protruding part 31 of the metal fitting cover 30 formed outside the engaged part 16a of the receiving part 16 in the finding direction. Thereby, the rotation restricting mechanism 20 releases the lock for the rotation of the handle 13. That is, in the state in which the inner impingement 4a and the outer impoverishment 4b are completely closed, the handle 13 of the crescent 10 is not restricted by the rotation restricting mechanism 20 and the hanging portion 12 is the engaged portion of the receiving portion 16. It can be rotated to a position engaging with 16a.

  FIG. 6 shows a cross-sectional view of the summoning rods 91 and 91 in a state where the inner shoji 4a and the outer shoji 4b are not closed. As shown in this figure, when the handle 13 of the crescent 10 is rotated in this state, the trigger portion 23 of the rotation restricting mechanism 20 protrudes from the box portion 11, and in this case, the protrusion portion 31 extends in the protruding direction of the trigger portion 23. Since there is no obstacle like this, it protrudes further to the outdoor side than the case of FIG. Then, the rotation restricting mechanism 20 locks the rotation of the handle 13 so that the handle 13 cannot be further rotated in the locking direction. As a result, it is possible to prevent the crescent from being hung up when the inner shroud 4a and the outer shroud 4b are not completely closed.

  In the state of FIG. 6, if the inner arm 4a or the outer arm 4b is moved while the handle 13 of the crescent 10 is held in a locked state to attempt to completely close the inner arm 4a or the outer arm 4b, the trigger portion 23 on the side of the crescent 10 is received. Interfering with the protrusion 31 on the part 16 side. However, the trigger portion 23 is formed so as to be retracted when pressed to the indoor side even when the handle 13 is locked, and the tip portion 23a of the trigger portion 23 and the tip portion 31a of the projection portion 31 are both chamfered at the corners. By being formed in a polygonal shape, the trigger portion 23 comes into contact with the protruding portion 31 in an inclined manner even when the inner shroud 4a or the outer shroud 4b is moved while the handle 13 is locked. Therefore, the trigger portion 23 is pushed into the box portion 11 by the protruding portion 31, and as a result, the handle 13 is unlocked by the rotation restricting mechanism 20 as shown in FIG. 5. In addition, you may form the front-end | tip part 23a of the trigger part 23 and the front-end | tip part 31a of the projection part 31 not only in polygonal shape but in circular arc shape. Moreover, it is good also considering only the protrusion part 31 as polygonal shape or circular arc shape.

  Further, the inner impingement 4a and the outer impingement 4b are opened larger than the state of FIG. 6, and the trigger portion 23 protrudes from the engaged portion 16a of the receiving portion 16 toward the inner position of the inner impingement 4a. Even in this case, the protruding portion 31 is formed above and below the engaged portion 16a of the receiving portion 16, and the trigger portion 23 is provided so as to abut against the protruding portion 31 formed above. Therefore, the trigger part 23 protruding from the box part 11 to the outdoor side does not interfere with the engaged part 16 a of the receiving part 16. Therefore, also in this case, the shojis 4 and 4 can be moved to be in a completely closed state while the handle 13 is locked.

  As described above, the protrusion 31 is formed in the receiving portion 16 at a position outside the engaged portion 16 a in the direction of finding, and the trigger portion 23 protrudes from the box portion 11 of the crescent 10 and comes into contact with the protrusion 31. Since the lock on the handle 13 is released, the hanging portion 12 is the same as that of a crescent that does not have an empty hanging prevention function, and the rotation restricting mechanism 20 can be hidden from the outdoor side. The sash can be highly effective in crime prevention. Further, since the horizontal position of the trigger portion 23 and the projection portion 31 is set above or below the engaged portion 16a of the receiving portion 16, the shoji is not completely closed and the trigger portion 23 protrudes. Even if the shoji is moved in this state, the sash does not interfere with the engaged portion 16a of the receiving portion 16 and the receiving portion 16 is not damaged by the trigger portion 23.

  Further, in a state where the handle 13 of the crescent 10 is locked, that is, in a state where the trigger portion 23 protrudes most outward, the front end of the hanging portion 12 is disposed on the indoor side of the front end of the trigger portion 23. As a result, even if the shoji is moved while the crescent 10 is in an empty state, the hanging portion 12 does not protrude outward from the tip of the trigger portion 23, so that it does not interfere with the receiving portion 16, and the hanging portion 12 It can be set as the sash which does not have a possibility of damaging the receiving part 16.
