The protrusion amount is reduced by the thickness of 116. For this reason, by projecting the tip on the inner peripheral side of the upper projection reinforcing member 32 from the main body inner plate surface 112 of the upper frame 11 to a position aligned with the tips of the projections 115 and 116, It is possible to provide a larger overlap margin where the side reinforcing portion 32b and the indoor side wall portion 26a or the outdoor side wall portion 26b of the groove reinforcing member 26 face each other in the prospective direction.

  Further, since the vertical protrusion reinforcing member 33 has an overhanging portion projecting inward from the inner protrusions 115, 135, 145 and the outer protrusions 116, 136, 146, it is exposed to a flame, for example. Thus, it is possible to hold the shoji 3 and 4 to the frame 10 more reliably even when the frame 10 and the flange 20 are melted.

  Further, the upper projecting portion reinforcing member 32 and the vertical projecting portion reinforcing member 33 are provided with the inner projecting portions 115, 135, 145 and the outer projecting portions 116, 136, 146 when the opening 10 a is closed by the inner shroud 3 and the outer shoji 4. In FIG. 2, since it is provided in a range facing each of the inner shoji 3 and the outer shoji 4, even if the opening 10a is closed and exposed to flame, the shoji 3 and 4 are more securely held in the frame 10. It is possible.

  Further, the water stop material 9 provided at each of the outer peripheral side end portions of the groove-shaped recess 21e in the upper collar 21 of the inner shroud 3 and the outer shroud 4 is the upper impact when the inner shroud 3 and the outer shroud 4 are opened and closed. Since it is slidably contacted with a part of the portion reinforcing member 32, the load during operation increases. For this reason, when the upper protrusion reinforcing member 32 is closed by the inner and outer obstacles 3 and 4, the inner protrusion 115 and the outer protrusion 116 face each of the inner and outer obstacles 3 and 4. By making it only, it is possible to reduce the load at the time of operation because the contact area of the water stop material with the upper protrusion reinforcement member 32 becomes smaller as the inner and outer obstacles 3 and 4 are opened.

  Further, the shojis 3 and 4 having the groove-shaped recesses 21e and 23e on the outer peripheral portion are built into the frame body 10 by a steadily method, so that the inner projecting portion 115 and the outer projecting portion 116 and the groove reinforcement in the vertical direction. A space is necessary between the member 26 and the shoji 3 and 4 so that the shoji 3 and 4 can be moved upward and removed, but in the left-right direction, that is, the groove reinforcing member 26 of the groove-like recess 23e provided in the door-end ridge 23 There is no need for a larger distance between the inner protrusion 115 and the outer protrusion 116 in the vertical direction. For this reason, by increasing the protruding amount of the vertical protrusion reinforcing member 33 provided on the left frame 13 and the right frame 14 that protrudes to the inner peripheral side from the upper protruding portion reinforcing member 32 provided on the upper frame 11, It is possible to further increase the allowance between the left frame 13 and the right frame 14 and the door toe 23. For this reason, even if it exposes to a flame, it is possible to hold | maintain the shoji 3 and 4 to the frame 10 more reliably.

  Further, the upper protrusion reinforcing member 32 and the vertical protrusion reinforcing member 33 have locking pieces 32c and 33c that are locked to the distal ends of the inner protrusions 115, 135, and 145 and the outer protrusions 116, 136, and 146, respectively. Therefore, the side reinforcing portion 32b of the upper protruding portion reinforcing member 32 and the side reinforcing portion 33b of the vertical protruding portion reinforcing member 33 are more reliably connected to the inner protruding portions 115, 135, 145 and the outer protruding portions 116, 136, 146. It is possible to follow. Further, since the protruding portion 33d of the vertical protrusion reinforcing member 33 is provided on the distal end side with respect to the locking piece 33c, the protruding amount is easily different by cutting away the portion on the distal end side from the locking piece 33c. It is possible to form the protruding portion reinforcing members 32 and 33.

  In the above embodiment, the frame members 11, 12, 13, and 14 forming the frame body 10 and the flange members 21, 22, 23, and 24 forming the flanges 20 are made of synthetic resin, the frame reinforcing member 30, and the fixed reinforcing bracket 31, the heel reinforcing member 25 and the groove reinforcing member 26 are made of iron, and the upper protruding portion reinforcing member 32 and the vertical protruding portion reinforcing member 33 are made of aluminum. However, the present invention is not limited to this, and the frame members 11, 12, 13, 14 and What is necessary is just to be formed with the material whose melting | fusing point is higher than the brazing materials 21, 22, 23, and 24 which form the collar 20.

  In the said embodiment, although the fitting 1 for sliding windows provided with the inner sward 3 and the outer sash 4 was demonstrated, it is not restricted to this, For example, for the single sliding window in which one sliding door is drawn in the sleeve wall side It is also possible to use a fitting for a three-panel sliding window or a four-panel sliding window whose opening can be closed by a plurality of shojis.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
