Since the fixing surface 42 is hidden from the side surface 42a in the drawing but the horizontal surface 42b is disposed on the lower surface side, the screw 5 can be inserted and screwed from below as in FIG. Then, the screw 5 can be inserted and screwed in from the outside in the longitudinal direction of the lower frame 22.

  In the upper right corner and the upper left corner of FIG. 3, the lattice side fixing surface 33 is arranged such that the upper surface 33 a and the lower surface 33 b face each other, and the vertical surface 33 c faces the outside in the longitudinal direction of the upper frame 21. 42, since the horizontal surface 42b is disposed on the side surface 42a and the upper surface side, the screw 5 can be inserted and screwed from above, and the screw 5 is inserted from the outside in the longitudinal direction of the upper frame 21 as necessary. It can also be screwed.

  By replacing the frame-side fixing part 40 in the lower right corner of FIG. 3 with the frame-side fixing part 40 in the upper right corner, the frame side fixing part 40 in the lower right corner has a horizontal plane 42b on the upper surface side, and the upper right corner Since the horizontal surface 42b is disposed on the lower surface side of the frame side fixing component 40, the horizontal surface 42b and the upper surface 33a can be brought into contact with each other at the lower right corner, and the horizontal surface 42b and the lower surface 33b can be brought into contact with each other at the upper right corner. . Thereby, when it is difficult to insert and screw the screws 5 from the outer peripheral side of the lattice body 20, the screws 5 can be inserted and screwed from the inner peripheral side of the lattice body. The lower left corner and the upper left corner can also be attached from the inner peripheral side of the lattice body 20 by exchanging the frame side fixing component 40.

  In this way, the lattice side fixing surface 33 of the lattice side fixing component 30 is formed so as to face a plurality of different directions, and the frame side fixing surface 42 of the frame side fixing component 40 is in contact with a plurality of the lattice side fixing surfaces 33. A plurality of surfaces are formed so as to be in contact with each other, and one of the surfaces is fixed with screws, so that the surface lattice 4 can be fixed to the sash frame 1 from a plurality of directions. The fixing direction can be selected according to the surrounding situation, and the attachment work of the surface lattice 4 can be facilitated.

  Further, while the lattice side fixing surface 33 has three surfaces, the frame side fixing surface 42 has two surfaces, but as described above, the frame side fixing component 40 is paired up and down, and the upper and lower sides are switched. In this way, any one of the three surfaces of the lattice side fixing surface 33 can be fixed. Thereby, the structure of the frame side fixed component 40 can be simplified and material cost can be reduced.

As shown in this figure, the lower frame 22 and the lower frame 11 of the lattice body 20 are also fixed by an intermediate connecting component 60 at an intermediate position in the longitudinal direction. The intermediate connecting component 60 abuts the lower surface of the surface lattice fixing portion 11b of the lower frame 11 and is fixed to the frame fixing surface portion 61 fixed by screws and the lower side protruding portion 26 of the lattice body 20 with respect to the lattice side fixing component 30. The grid fixing surface portion 62 is fixed by the same structure as the base portion 31, and the frame fixing surface portion 61 and the connecting surface portion 63 that connects the lattice fixing surface portion 62 are configured.

  The side cover member 50 covers the lattice-side fixing component 30 and the frame-side fixing component 40, and the outdoor end surface thereof is in contact with the sash frame body side surface of the lattice body 20. Thereby, the design continuity from the grid body 20 to the side cover member 50 and the sash frame 1 can be achieved, and the design can be improved. Moreover, since the side cover member 50 does not cover the side surface of the lattice body 20, the design property when the lattice body 20 is viewed from the side can be improved.
