However, the present invention is not limited to the half-folded sash, and the present invention can be applied to, for example, a one-sided sash.

  The opening / closing material 2 is assembled on the surface of the lower wing 1 of each of the shojis Da and Db according to the embodiment, and the closing material 2 is automatically lowered below the lower shovel 1 when the shoji is closed. Then, the gap between the lower rod 1 and the lower frame 3b of the sash A is closed, and when the shoji is opened, the closing material 2 is automatically raised and the floor surface a existing on the same surface as the lower frame 3b. The contact is avoided, and the opening operation of the shoji Da, Db can be performed smoothly.

  The closing member 2 is assembled to the lower arm 1 of the corresponding shoji Da, Db using a pair of guide members 4, 4 and engaging members 5, 5, and the guide member 4 is provided on one side of the main plate 6. The L-shaped strips 7a and 7a are protruded relative to each other, and the guide grooves 7 and 7 are vertically provided so as to be gradually inclined downward from the shoji hanging side toward the door-end side. 7, 7 (strip pieces 7a, 7a) are provided on the upper side between the U-shaped stopper pieces 8 and 8 having a lower opening and the lower end of the main plate 6 at the center between the stopper pieces 8 and 8. The protruding piece 9 arranged at the position is arranged along the inclination of the guide groove 7.

  The guide member 4 is fixed to the support plate 11 attached to the lower rod 1 by attachment means 10, 10 with screws 12, and the engagement member 5 provided on the closing member 2 side is attached to the guide member 4. The closing material 2 is assembled to the lower collar 1 by sliding fitting.

  The engaging member 5 is made thin at both ends of the main plate 13 and is inclined by the same angle as the inclination angle of the guide groove 7 of the guide member 4. 4, the main plate 13 is inclined at the same angle as the inclination angle of the guide groove 7 on the side of the main plate 13 facing the main plate 6 of the guide member 4, and the deep deep groove 15 in the center and the deep A shallow inclined groove 16 is provided on both sides of the inclined groove 15, and a coil spring 17 is provided between the abutting wall 15 ′ at the upper end of the deep inclined groove 15 and the protruding piece 9 on the guide member 4 side fitted in the inclined groove 15. Is disposed in the deep inclined groove 15, and is engaged with the stopper portion pieces 8, 8 on the guide member 4 side slidably fitted in the shallow inclined groove 16. Protrusions 18 are provided, and are interposed between upper and lower sandwiching pieces 2a and 2b projecting in the direction of the lower eyelid 1 at the upper end and the middle of the closing material 2, The upper assembly piece 19a protruding from the upper end of the body plate 13 is provided in the engagement hole 20a provided in the upper holding piece 2a, and the lower assembly piece 19b protruding from the lower end is provided in the lower holding piece 2b. They are respectively locked in the engagement holes 20b and fixed to the closing material 2.

  The closing material 2 has a synthetic resin end piece 2B attached to one end of the metal main frame 2A provided with the holding pieces 2a and 2b, and a sealing material on each of the three edges except the upper edge. 21 is attached, and the upper corner portion of the end piece 2B on the side of the shoji hanging side is inclined to form a press-contacting edge 22, and the pressure-receiving edge 22 'is press-contacted at the time of closing the shoji. The provided block body 23 is formed below the vertical frame 3c of the window frame A.

  The pressure receiving edge 23 ′ of the block body 23 is positioned on the rotation path of the pressure contact edge 22 associated with the rotation of the shoji closing operation, exhibits an inclined shape, and when the pressure contact edge 22 rotates in the shoji closing direction, The pressure contact edge 22 is pressed by the biasing force of the coil spring 17, and the pressure contact edge 22 is lowered by the inclined shape, that is, the closing member 2 (the end piece 2B provided with the pressure contact edge 22 and the main frame 2A). The closing plate 2 closes the lower part of the lower rod 1 (the gap a between the lower rod 1 and the lower frame 3b) by this lowering.
