  When the handle is operated with the above configuration, the interlocking plate is moved by the cam via the connecting plate, and the locking member can be engaged with or disengaged from the locking receiver of the frame frame. Referring to FIG. 11, in detail, (A) is the locked state, (B) is the moment of leaving the locked state, (C) is the state in which the connecting plate is started to move from the locked position to the unlocked position, (D ) Shows a state in which the connecting plate starts to move from the unlocked position to the locked position, (E) shows the moment of leaving the unlocked state, and (F) shows the unlocked state. In the state of FIG. (A), the action portion 20 of the cam 16 is in contact with the inclined cam surface 56 formed on the driven cam portion 54 of the connecting plate 53, the side surface of the action portion 20 is in contact with the stopper pin 26, and the handle 15 The boss portion 35 of the leaf spring 32 is engaged with the positioning hole 22 formed in the action portion 20 of the cam 16 and is temporarily held at that position. When the handle 15 is rotated in the unlocking direction (arrow direction), the cam 16 rotates about the pivot 28 and the action portion 20 slides on the inclined cam surface 56, and as shown in FIG. Just before the surface 56 comes off. In the locked state shown in FIG. (A), even if the interlocking plate 49 is moved from the outside in the unlocking direction, the action portion 20 of the cam 16 is at the dead center with respect to the inclined cam surface 56, and the handle is temporarily Since it is held, it cannot be moved.

  Between FIG. (B) and FIG. (C), since the action part 20 of the cam 16 enters between the driven cam parts 54 of the connecting plate 53, the connecting plate 53 does not move, and the interlocking plate 49 is still locked. However, if the interlocking plate 49 is to be moved from the outside, it can be moved. In the state shown in FIG. 3C, the action portion 20 of the cam 16 starts to push the other driven cam portion 54 of the connecting plate 53, so that the connecting plate 53 starts to move in the unlocking direction. In the state shown in FIG. 5E, the connecting plate 53 moves until the tip of the cam action portion 20 contacts the inclined cam surface 56 of the driven cam portion 54. However, when the tip contacts the inclined cam surface 56, the connecting plate 53 is moved. Is stopped, and the interlocking plate 49 is unlocked.

  In the state of FIG. (E) and FIG. (F), the action part 20 enters the inclined cam surface 56. Therefore, even if the interlocking plate 49 is operated from outside to lock the action part 20, the tip of the action part dies with respect to the inclination cam surface. Since it is in a dot, the interlocking plate cannot be moved. When the state of FIG. (F) is reached, the tip of the action portion 20 completely slides into the inclined cam surface 56, and the side surface of the action portion 20 hits the stopper pin 26, and unlocking is completed. At this time, the handle 15 is temporarily held in the unlocked position by the boss portion 35 of the leaf spring. In the embodiment shown in the figure, the handle extends below the pivot in the locked position and becomes almost horizontal in the unlocked position. When the handle is pushed, the shoji opens, and when pulled, the shoji closes. The position can be determined in various directions, for example, the handle can be arranged above the pivot in the locked position.

  To lock from the unlocked state, the operation is the reverse of the above. That is, when the handle 15 is rotated in the locking direction (arrow direction) from the state shown in FIG. (F), the tip of the action portion 20 of the cam 16 slides on the inclined cam surface 56 of the driven cam portion 54, as shown in FIG. Thus, the tip reaches just before it comes off the inclined cam surface. Between FIG. (F) and FIG. (E), since the tip of the action portion is at the dead center with respect to the inclined cam surface, the interlocking plate 49 cannot be moved from the outside. Between FIG. (E) and FIG. (D), the tip of the action portion 20 is out of the inclined cam surface 56, so that it enters a neutral position. During this time, since the connecting plate 53 does not move, the interlocking plate 49 is in an unlocked state, but can be moved if it is moved in the locking direction.

  As shown in FIGS. (D) to (B), when the handle is further rotated in the state of FIG. (D), the interlocking plate 49 is pushed out in the locking direction via the connecting plate 53 by the action portion 20 of the cam. When the tip of 20 is in contact with the inclined cam surface 56, the connecting plate 53 stops moving, and the interlocking plate 49 is locked. Between FIG. (A) and FIG. (B), even if it is going to move an interlocking plate from the outside until the action part 20 slides on the inclined cam surface 56, the action part 20 enters a dead center with respect to the connection plate 53. Therefore, the interlocking plate 49 does not move. When it moves to the position shown in FIG. (A), the tip of the action portion 20 comes into contact with the inclined cam surface 56 and comes into contact with the stopper pin 26, so that the handle 15 cannot be rotated any further.
