It is sectional drawing which shows the crimping structure by a 3rd modification.

Hereinafter, the frame body of the sliding window according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4.
In the sliding window 1 according to the embodiment shown in FIG. 1, an upper frame, a lower frame, and left and right vertical frames 4 are formed in a quadrangular frame shape as a frame body 3 fixed to an opening 2a of a frame body 2. An external shoji screen 6 and an internal shoji screen (not shown) are openably and closably housed in the frame body 3. In the frame body 3, a resin frame is connected to the indoor side of the metal frame.
FIG. 1 shows a horizontal sectional view of one of the vertical frames 4, and the vertical frame 4 is housed on the outdoor side of the opening 2 a of the frame 2. The vertical frame 4 shown in FIG. 1 and FIG. 2 is composed of a metal vertical frame 5 and a resin vertical frame 8 fixed to the indoor side thereof, and is installed on both left and right sides of the frame body 3 so as to face each other.

The metal vertical frame 5 is formed in a substantially T shape in a horizontal sectional view, and a plate-shaped main body portion 5a extends in the indoor / outdoor direction, and a branch portion 5b branched in the middle extends to the body 2 side and the fixing screw 10 is formed. It is fixed to the body 2 by. A caulking frame 5c bent in a substantially U shape is formed at the indoor side end of the main body 5a of the metal vertical frame 5, and a tip piece 5d branched from the caulking frame 5c and further extending to the indoor side is fixed by a fixing screw 10. It is fixed to the body 2. A first locking portion 9 having a substantially L-shaped cross section for locking the resin vertical frame 8 is formed on the outdoor side of the main body portion 5a.
The caulking frame 5c is formed in a substantially U-shaped cross section by the abutting portion 11, the connecting portion 12, and the elastically deformable first engaging portion 13, and the first engaging portion 13 has a claw portion 13a at its tip. Is forming.

  On the other hand, the resin vertical frame 8 has a plurality of hollow hollow portions, and the outdoor side end thereof is, for example, a substantially L-shaped second latched to the first locking portion 9 of the metal vertical frame 5. The locking portion 15 is formed. Further, an indoor piece 8a is formed at the indoor end of the resin vertical frame 8, and one end thereof is bent into a substantially L shape and locked to the frame 16. The other end side of the indoor piece 8a is bent to the outdoor side and is elastically deformable having a claw portion 17a which is inserted into the caulking frame 5c of the metal vertical frame 5 and engages with the first engaging portion 13. A joint 17 is formed. The second engaging portion 17 has a slight gap with the abutting portion 11 within the crimping frame 5c.

The metal caulking frame 5c and the resin second engaging portion 17 constitute a caulking portion 19. In the caulking portion 19, the first engaging portion 13 and the abutting portion 11 are deformed between the first engaging portion 13 and the abutting portion 11 as shown in FIG. Thus, the resin-made second engagement portion 17 can be sandwiched and fixed.
Moreover, the caulking portion 19 is provided between the opening 2a of the skeleton 2 and the frame 16, and the caulking portion 19 is not exposed to the indoor side by pushing and fixing the separate member 20 to the indoor side of the space. . The metal vertical frame 5 is integrally formed with the caulking frame 5c and the first engaging portion 9, and the resin vertical frame 8 is also integrally formed with the second engaging portion 17 and the second engaging portion 15.

The sliding window 1 according to the present embodiment has the above-mentioned configuration. Next, when assembling the frame body 3 of the sliding window 1, a method of assembling the metal vertical frame 5 and the resin vertical frame 8 of the left and right vertical frames 4 will be described. To do.
In FIGS. 1 and 2, for example, at the stage before factory shipment, the tip of the second engaging portion 15 provided on the outdoor side end of the resin vertical frame 8 is attached to the first engaging portion 9 provided on the metal vertical frame 5. The resin vertical frame 8 is relatively rotated toward the wall surface of the opening 2a with the second locking portion 15 as a fulcrum.
Then, the second engaging portion 17 of the resin vertical frame 8 is inserted through the opening of the caulking frame 5c of the metal vertical frame 5 fixed to the frame 2, and the claw portion 13a of the first engaging portion 13 of the metal vertical frame 5 is inserted. The claw portion 17a of the second engaging portion 17 is abutted and elastically deformed toward the abutting portion 11 side to get over and enter the engaged state. As a result, the resin vertical frame 8 is held so as not to come off in the horizontal direction with respect to the metal vertical frame 5.

Next, the caulking operation member (not shown) sandwiches the contact portion 11 and the first engaging portion 13 of the caulking frame 5c of the metal vertical frame 5 and presses them together. Then, as shown in FIG. 3, the arm portion on the proximal end side of the claw portion 13a of the first engaging portion 13 is deformed into a substantially V shape or a substantially U shape so that the second arm of the resin vertical frame 8 together with the claw portion 13a is deformed. The front and rear sides of the claw portion 17a of the engaging portion 17 are pressed against the abutting portion 11 to slightly deform the second engaging portion 17. As a result, the second engaging portion 17 of the resin vertical frame 8 is pressed and fixed to the caulking frame 5c of the metal vertical frame 5 not only in the horizontal direction but also in the vertical direction. As shown in FIG. 4, a recessed caulking trace of the caulking portion 19 is formed on the indoor side surface of the first engaging portion 13 of the metal vertical frame 5.
Finally, the assembled vertical frame 4 is attached to the opening 2a of the body 2 at the construction site and fixed with the fixing screw 10. Then, on the indoor side of the caulking portion 19, by inserting another member 20 into the space between the opening 2a and the frame 16, the caulking portion 19 becomes invisible and the design is improved.
