Further, the pin insertion hole 42 described above is provided in the buffer stopper 8 attached to the left and right side portions 23 and 24 of the sash frame 2 where the side edges of the window glass are distributed. It is provided so as to be located within the thickness. 1, FIG. 2 and FIG. 3 show a sash 1 in which a frame body 2 into which the surface lattice main bodies 3A and 3B are inserted and a window frame 6 are integrally formed. The fixing pin 5 is pulled out from the inserted state of FIG. 2 to the inside of the room as shown in FIG. 3, so that the lattice main body 3 can be moved to one side and can be opened. The lower side portion 26 of the frame body 2 into which the respective surface lattice main bodies 3A and 3B are distributed has two recessed groove type rail shapes as shown in FIG. 4 and two recessed groove type rail shapes as shown in FIG. There is a convex rail shape.

Further, when the lower portion 26 of the frame body 2 into which the respective surface lattice main bodies 3A and 3B are distributed has a two-convex rail shape, as shown in FIG. When the door wheels 9 are mounted on the lower frames 33, 33 of 3A, 3B, there is an advantage that the sliding condition is improved when the surface lattice main body 3 is moved to one side.

As shown in FIG. 7, a disk-shaped pulling portion 51 having a circular hole 511 is provided at the indoor end of the fixing pin 5. As described above, the provision of the pull tab 51 has an advantage that the fixing pin 5 can be easily pulled out toward the indoor side.

As shown in FIG. 8, the right frame 11 of the sash 1 is provided with a lever means 7 A for pulling out the fixing pin 5 by pulling. The lever means 7A comprises a horizontal portion 71 whose base is fixed to the right frame 11, and a vertical portion 72 whose lower end is pivotally attached to the tip of the horizontal portion 71, and the substantially central portion of the vertical portion 72 is fixed. The pin 5 is pivotally attached to the indoor end. When the vertical portion 72 is pulled toward the indoor side, the vertical portion 72 is rotated about the pivot point of the horizontal portion 71, and the fixing pin 5 is pulled out toward the indoor side accordingly. Therefore, the fixing pin 5 can be easily pulled out.

As shown in FIG. 9, a lever means 7 B for pulling out the fixing pin 5 by pushing the right frame 11 of the sash 1 is provided. The lever means 7B has a lower end pivoted to a vertical portion 73 pivotally attached to the indoor end of the fixing pin 5 and a base fixed to the right frame 11 so that the distal end is pivoted to a portion lower than the central portion of the vertical portion 73. And a horizontal portion 74 that is worn. When the upper part of the vertical part 73 is pushed outward, the lower part of the vertical part 73 rotates toward the room (front side) around the pivot point of the horizontal part 74, and the fixing pin 5 is accordingly moved. It is pulled out indoors. Therefore, the fixing pin 5 can be easily pulled out.

As shown in FIG. 10, a plate-shaped base portion 13 having a front plate wall portion 131 fixed to the right frame 11 side of the sash 1 and a rotatably pivotally attached to a substantially central portion of the plate-shaped base portion 13. One end is fitted into a substantially wide L-shaped operating rod portion 14 and a finger portion 141 provided integrally with a corner portion of the operating rod portion 14, and the other end is a lower portion of the plate-like base portion 13 described above. It is composed of a substantially U-shaped urging spring 16 fitted in a pin 15 projecting from the side of the inner side of the chamber, and is provided near the tip of the upward-facing piece 141 of the substantially wide L-shaped operating rod portion 14 described above. The pull-out operation tool 18 has the protruding pin 52 at the indoor end of the fixing pin 5 fitted into the formed horizontal heart-shaped hole 17. When pulling out the fixing pin 5, as shown in FIG. 10, when the sideways piece 142 of the substantially wide width L-shaped operating rod portion 14 of the pulling-out operation tool 18 is pushed downward, the operating rod portion 14 is pivoted. Is rotated clockwise about the axis, the projecting pin 52 at the indoor end of the fixing pin 5 moves to the prepared hole 171 of the horizontal heart-shaped hole 17, and the operating rod 14 is rotated clockwise. Since the upward piece 141 moves toward the indoor side, the fixing pin 5 is pulled out toward the indoor side accordingly.

Further, in order to lock the tip of the fixing pin 5 into the pin insertion locking hole 351 of the right frame 35 of the surface lattice main body 3 and prevent the surface lattice main body 3 from being detached and fixed, As shown in FIG. 11, when the sideways piece 142 of the substantially wide L-shaped operating rod 14 of the pull-out operating tool 13 is pushed upward, the operating rod 14 rotates counterclockwise about the pivot point. As a result, the upward piece 141 of the operating rod portion 14 moves to the surface lattice main body 3 side. At this time, the protruding pin 52 at the indoor end of the fixing pin 5 moves to the upper hole 172 of the horizontal heart-shaped hole 17, and is pushed by the hole wall to push the fixing pin 5 to the surface lattice main body 3 side. The tip is engaged with the pin insertion locking hole 351 of the right side portion 35 of the surface lattice body 3.

In this state, the projecting pin 52 at the indoor end of the fixing pin 5 is located in the upper hole 172 of the sideways heart-shaped hole 17, and the operating rod portion 14 is biased counterclockwise by the biasing spring 16. Since it is biased, even if the tip of the fixing pin 5 inserted into the pin insertion locking hole 351 of the right side portion 35 of the surface lattice main body 3 is pushed to the indoor side, the operating rod portion 14 is not operated. It is not rotated in the direction. Therefore, when the pulling-out operation tool 18 is used, it becomes impossible to pull out the fixing pin 5 from the outside to the inside of the room, and the plane lattice main body 3 cannot be moved and opened. Thereby, an excellent crime prevention effect can be exhibited.

Before the fixing pin 5 is pushed to the surface lattice main body 3 side, the state shown in FIG. 12 is obtained. That is, the front end portion 54 of the fixing pin 5 on the surface lattice main body 3 side and the locking rod 56 are substantially on the same line in the horizontal direction, and the downward key portion 561 of the locking rod 56 is located on the right side frame 35 of the surface lattice main body 3. It is located on the upper side of the pin insertion locking hole 351 having a drooping hole shape. From this state, when the fixing pin 5 is further pushed to the surface lattice main body 3 side, as shown in FIG. 13, the projecting pin 562 provided at the indoor end of the locking rod 56 is attached to the tip 54 of the fixing pin 5. It moves to the lower end of the inclined elongated hole 55 on the indoor side. Then, the locking rod 56 is rotated by its own weight in the clockwise direction about the protruding pin 562, and the protruding end portion of the downward key portion 561 is inserted into the right side portion 35 of the surface lattice main body 3 in the form of a pin. The V-shaped slope 352 on the indoor side of the locking hole 351 is hit and locked. In this state, even if the locking rod 56 is pushed from the outdoor side toward the indoor side, the locking rod 56 does not come out from the pin insertion locking hole 351 to the indoor side. Therefore, an excellent crime prevention effect is exhibited.

Further, when the locking rod 56 is pulled out from the indoor side through the pin insertion locking hole 351 of the right side frame 35 of the surface lattice main body 3, when the fixing pin 5 is pulled toward the indoor side, The projecting pin 562 of the stop rod 56 moves to the upper end portion on the side of the plane lattice main body 3 along the hole wall of the inclined elongated hole 55 of the tip end portion 54 of the fixing pin 5, so that the state shown in FIG. Since the projecting end of the downward key portion 561 of the locking rod 56 and the hanging hole-shaped pin insertion locking hole 351 of the right side portion 35 of the surface lattice main body 3 are unlocked from the indoor V slope 352, the locking state is released. By further pulling the fixing pin 5 toward the indoor side, the downward key portion 561 of the locking rod 56 is easily pulled out from the pin insertion locking hole 351 to the indoor side.
