Description

  The present invention relates to a sash that can prevent a finger from being pinched between a shoji and a stand when opening the shoji.

  With a sash that allows the door to be fully opened by retracting the shoji to the outside of the wall or stationary shoji, when the shoji is opened, the door bottom side of the shoji (the rear end of the shoji when the shoji moves in the opening direction) Since the heel is pulled apart from the vertical or the like, if the shoji is opened by grasping the heel on the Tojiri side, there is a risk that a finger may be caught between the heel and the vertical. As a countermeasure, a pinch prevention tool is attached to the shoji. Finger pinching prevention devices are generally equipped with a stopper that can be moved in and out, and an operation unit that allows the stopper to be moved in and out, and the usage method is to keep the stopper in a protruding state when the shoji is closed. When the shoji is opened, the stopper is brought into contact with the vertical or the like, and the movement of the shoji is restricted before the shoji is fully opened. Thereafter, the operating portion is operated to retract the stopper to make the shoji fully open. After closing the shoji, operate the operation unit to return the stopper to the operating state. With such a finger pinching prevention tool, there is a risk of forgetting to return the stopper to the operating state when the shoji is closed. In addition, even if the stopper is returned to the operating state once, the user may mistakenly operate the operation unit while the shoji is closed and the stopper may be inactive.

  Patent Document 1 discloses a finger pinching prevention tool for preventing a finger from being pinched between the heel and the heel frame of the shoji door when the shoji is closed in a normal sliding sash. ing. This finger pinching prevention tool includes a case 20 attached to an upper frame, a trigger 30 and a stopper 60 that are pivotally supported by the case so as to be able to protrude and retract from the case, and a stopper that is built in the case according to the operation of the trigger. It has a slider 40 and a slide regulating piece 50 for operating. When the shoji is opened, the trigger 30 protrudes from the case and the stopper 60 is immersed in the case. 30 is pushed by the door toe 134 and is immersed in the case, and accordingly, the stopper 60 protrudes from the case to restrict the movement of the shoji. After that, when the shoji is returned to the open side a little and then closed again, the trigger 30 moves in and out, and accordingly, the stopper 60 gets into the case and the shoji can be fully closed. When the shoji is opened, only the trigger 30 protrudes. In this finger pinching prevention tool, the operation of switching the action / non-action state of the stopper 60 is unnecessary.

The finger pinching prevention tool described in Patent Document 1 is not directly applicable to the device that prevents finger pinching when opening the shoji by pulling it out to the outside of the wall as described above. Further, in this finger pinching prevention device, every time the trigger 30 is pressed, the stopper 60 is alternately switched between a protruding state and an immersive state. Therefore, if the child plays with the trigger 30 while the shoji is open, the shoji The stopper does not work when closing. Further, this finger pinching prevention tool transmits the movement of the trigger 30 to the stopper 60 via the slider 40 and the slide restricting piece 50. The slider 40 and the slide restricting piece 50 have a very complicated structure using a cam mechanism. Therefore, there is a possibility that the cam part may be worn out during long use, or dust may be attached to the cam part, resulting in malfunction.

When opening the inner shoji 2, the left heel 8 is grasped from the indoor side and moved to the right. At this time, as shown in FIG. Since it abuts on the left side surface, the movement of the inner impingement 2 is restricted slightly before the inner impingement 2 is fully opened, thereby preventing pinching between the heel 8 and the stand 3.
Thereafter, as shown in FIG. 5C, when the stopper member 13 is pushed in from the room side with a finger to be immersed in the case 10, the arm 12 engages with the engaging portion 15 of the case and the arm 12 rotates. Since the movement is restricted and the stopper member 13 is held in an immersive state, as shown in FIG. 5-2 (d), move the inner shoji 2 to the right until the heel 8 overlaps the outside of the vertical 3 Then you can fully open the shoji. At this time, the switch member 14 protrudes from the case 10.
Thereafter, when the inner impeller 2 is moved leftward to close the inner impeller 2, the corner of the vertical 3 abuts against the left inclined surface 14b of the switch member 14 as shown in FIG. As shown in FIG. 5-2 (f), the switch member 14 is pushed by the vertical 3 and is immersed in the case 10, and accordingly, the arm 12 is disengaged from the engaging portion 15, and the stopper member 13 is connected to the coil spring 32. It protrudes by the biasing force. Thus, since the finger pinching prevention tool 9 automatically returns to the stopper operating state when the inner shroud 2 is closed, the user can never forget to apply the stopper.

  When the user accidentally pushes the stopper member 13 into the case 10 while the inner impeller 2 is closed and the inner impeller 2 is opened in the non-operating state of the stopper, as shown in FIG. Since the corner of the vertical 3 abuts against the right inclined surface 14a of the switch member 14, the switch member 14 is pushed by the vertical 3 to be immersed in the case 10, and accordingly, the stopper member 13 protrudes from the case 10 and enters the stopper action state. Since it returns, finger pinching can be prevented in the same way.

  Even if the finger pinching prevention device 9 malfunctions due to vibration or the like and is in a stopper action state while the inner impeller 2 is open, as shown in FIG. When the corner of the vertical 3 abuts, the stopper member 13 is pushed by the vertical 3 and immerses in the case 10, so that the inner shoji 2 can be closed as usual without removing it from the frame.

  In the present embodiment, the right side of the frame 1 is closed by the wall 4, but a fixed shoji is provided on the right side in the frame 1, and the inner shoji 2 and the external shoji 20 are stored outside the fixed shoji.
