  In the sash 1, when the shoji 3, 4 is moved by mistake while the shoji 3, 4 is pulled to one side and the cover 37, 39b, 39a is removed, the shoji 3, 4 is moved to the cover 37b, 39b, 39a. In order to prevent this from falling off (removing from the wheel) on the removed lower frame 2b, as shown in FIGS. 19, 20, 21 to 22, cover members 37b, 39b Alternatively, the lower frame 2b below 39a automatically protrudes above the lower frame 2b by means of, for example, a spring which is a biasing means when the cover material 37b, 39b or 39a is removed, and the cover material 37b, 39b or 39a is removed. A stopper 86 that prevents the shoji 3 and 4 from moving to the other side is provided. In the illustrated example, the vertical saddle 6c, 8d of each shoji 3 and 4 is placed on the partition wall 25 of the lower frame 2b under the shoji-side indoor-side cover material 37b, the shoji-side outdoor-side cover material 39b, and the inner-shoulder-side indoor outer cover material 39a. A total of three shoji drop prevention stoppers 86 are attached in proximity to the end of 8c. The external cover side intermediate cover member 38b protrudes from the sump 8c of the external cover 4 by the amount of the open cover stopper 86, and the extended cover stopper 86 is provided on the partition wall 25 of the lower frame 2b. An opening 87 for attachment is provided (see FIG. 21). The inner cover side intermediate cover member 38a is formed to have a shorter length by the protruding portion of the outer cover intermediate cover member 38b.

  The shoji drop-off prevention stopper 86 is pivotally supported via a pin 90 between a metallic base portion 89 having a pair of rising pieces 88 and a compatible rising piece 88 via a pin 90, and is mounted on the base portion 89. For example, it is possible to rotate between a horizontally lying storage position (i) and an operating position (b) standing at an inclination angle of approximately 45 degrees obliquely upward toward the ends of the vertical rods 6c, 8c, 8d of the shojis 3, 4. It is mainly composed of a resin stopper piece 91 and a spring 92 that urges the stopper piece 91 to change from the storage position A to the operating position B. At the rear end portion of the stopper piece 91, there is provided a rotation restricting portion 91b that abuts on the upper surface of the base portion 89 and restricts further rotation when it reaches the operating position b. When the stopper piece 91 is in the operating position b, when the shoji 3 and 4 are moved to the stopper side, the ends of the vertical rods 6c, 8c and 8d of the shoji 3 and 4 or the ends of the steady members 44 and 45 are the stopper piece 91. The shoji 3 and 4 are prevented from moving by abutting against the tip 91a (see FIGS. 22A and 22B).

  In order to attach the base portion 89 to the partition wall 25 of the lower frame 2b with mounting screws 93, the base portion 89 is provided with holes 94 at least in the longitudinal direction, and the mounting screws 93 are screwed into the partition wall 25 of the lower frame 2b. A mating female screw hole 95 is provided. The hole 94 is preferably a long hole that allows adjustment of the mounting position of the base portion 89.

  The attachment screw 93 of the base portion 89 is rarely detached once attached, but the screws 40, 41 of the cover members 37b, 39b, 39a are detached each time the cover members 37b, 39b, 39a are detached. If the female screw hole 96 for screwing the screws 40, 41 of the cover members 37b, 39b, 39a is provided in the partition wall 25 of the aluminum lower frame 2b, the screw thread of the female screw hole 96 is damaged, and the cover There is a possibility that the attachment of the materials 37b, 39b, 39a may be difficult. In order to solve this problem, a female screw hole 96 for screwing the screws 40, 41 of the cover members 37b, 39b, 39a into the base part 89 made of stainless steel harder than aluminum is provided. A large hole 97 for avoiding interference with the screws 40 and 41 is provided in portions corresponding to the screws 40 and 41 of the cover members 37b, 39b and 39a in the partition wall 25 of the lower frame 2b.

  In the middle of the screws 40 and 41, when the screws 40 and 41 are loosened, they come into contact with the lower surfaces of the cover members 37b, 39b and 39a and the screws 40 and 41 protrude from the upper surfaces of the cover members 37b, 39b and 39a. A locking portion 98 for stopping is provided, and the cover members 37b, 39b, 39a can be easily removed by gripping the protruding portions (screw head side) of the protruding screws 40, 41.

  According to the sash 1 having the above configuration, when the shoji 3 is pulled to one side and the cover material 37b on the upper surface of the lower frame is removed as shown in FIG. The stopper piece 91 of the shoji drop prevention stopper 86 that has been pushed into the a is released and is automatically rotated to the operating position B with the pin 90 as a fulcrum by the biasing force of the spring 92, and the shoji 3 is located above the lower frame 2b. It protrudes so as to face the end of the vertical rod 6c or the steadying member 45. For this reason, as shown in FIG. 22B, even if the shoji 3 is erroneously slid to the side from which the cover member 37b is removed, the vertical frame 6c of the shoji 3 or the steadying member 45 The end portion 91a of the stopper piece 91 hits the end portion, and the movement of the shoji 3 is prevented, thereby preventing the shoji 3 from dropping off.

  When the cover member 37b is attached to the upper surface of the lower frame 2b after cleaning or the like is completed, the stopper piece 91 of the shoji drop-off prevention stopper 86 is pushed into the storage position i on the base portion 89 against the biasing force of the spring 92 [ As shown in FIG. 22 (c), the shoji drop prevention stopper 86 can be stored so as not to get in the way, and the shoji 3 can be slid along the cover member 37b.

  As described above, the sash 1 includes the frame 2 including the upper and lower frames 2a and 2b and the left and right vertical frames 2c and 2d, and the shojis 3 and 4 provided in the frame 2 so as to be opened and closed in the left and right directions. The upper surface of the lower frame 2b is formed in a substantially flat surface, and the upper surface of the lower frame 2b is divided into a plurality of cover members 37b, 39b, 39a, and the shojis 3, 4 are arranged on one side. The cover members 37b, 39b, 39a can be detached by pulling them, and when the cover members 37b, 39b, 39a are removed from the lower frame 2b below the cover members 37b, 39b, 39a, a biasing means such as a spring 92 is used. Since the shoji dropout prevention stopper 86 that automatically protrudes above the lower frame 2b and prevents the shoji 3 and 4 from moving to the side from which the cover materials 37b, 39b, 39a are removed is provided, the cover on the lower frame 2b is provided. Material 37b 39 b, it is possible to prevent the falling off of the shoji 3,4 even moved shoji 3,4 accidentally in a state of removed 39a. Therefore, there is no possibility that the shoji falls due to the falling off of the shoji, the safety and the reliability can be improved, and the return work accompanying the dropping of the shoji becomes unnecessary.

  The shoji drop prevention stopper 86 is pivotally supported via a pin 90 between a metal base having a pair of rising pieces 88, for example, stainless steel, and a compatible rising piece 88. It is possible to rotate between the storage position a lying down horizontally and the operating position B standing up at an inclination angle of approximately 45 degrees obliquely upward toward the ends of the vertical rods 6c, 8c, 8d of the shoji 3, 4 For example, since it is mainly composed of a stopper piece 91 made of resin and a spring 92 that urges the stopper piece 91 to move from the storage position A to the operating position B, the structure is simple and the cost is reduced. Can be planned. Further, since the screws 40, 41 of the cover members 37b, 39b, 39a are screwed and fixed to the base portion 89 made of stainless steel, the screws 40, 41 are attached to the partition wall 25 of the aluminum lower frame 2b. Unlike the case of fixing by screwing, the thread of the female screw hole 96 is hardly damaged, and durability can be improved.
