The front cover 8 can be reversed and attached to the flange portion 11 and the corner members 6 and 7, and a good fitting state can be obtained.

Next, an example of attaching the front cover 8 will be described mainly with reference to FIG.
First, as shown in FIG. 6A, when the front cover 8 is attached to the flange portion 11, the front end of the first locking plate portion 44 of the front cover 8 is brought into contact with the contact surface 27 of the flange portion 11. When attached, the locking claw 46 of the first locking plate portion 44 is locked to the locking portion 25 of the second locking rib 22 and the locking claw 46 of the second locking plate portion 45 is locked. The first locking rib 21 is locked by the locking portion 26. At the same time, the convex portion 51 of the front cover 8 abuts on the end surface 21 b of the first locking rib 21, and the lid portion 43 of the front cover 8 is held in a posture parallel to the flange portion 11. At this time, the side surface 44b of the first locking plate portion 44 of the front cover 8 and the substrate portion 10c are flush with each other, improving the appearance in the window connection frame 1 and the drainage of residual water. .

  Further, as shown in FIG. 6 (b) in reverse with the above, when the tip of the second locking plate portion 45 of the front cover 8 is attached so as to contact the contact surface 27 of the flange portion 11, The locking claw 46 of the second locking plate portion 45 is locked to the locking portion 25 of the second locking rib 22, and the locking claw 46 of the first locking plate portion 44 is locked to the first locking rib 21. It will be latched by the latching part 26 of the back side. At the same time, the convex portion 51 of the front cover 8 abuts on the end surface 22 b of the second locking rib 22, and the lid portion 43 of the front cover 8 is held in a posture parallel to the flange portion 11. Further, at this time, the side surface 45b of the second locking plate portion 45 of the front cover 8 and the substrate portion 10c are flush with each other, so that the appearance in the window connection frame 1 and the drainage of residual water are improved. ing.

  Here, as is clear from FIGS. 6A and 6B, when the first locking plate portion 44 is brought into contact with the contact surface 27, the second locking plate portion 45 is brought into contact with the contact surface. The protrusion height of the front surface 8b of the front cover 8 is higher than that in the case where it is brought into contact with the front cover 8, and conversely, when the second engagement plate portion 45 is brought into contact with the contact surface 27, the first engagement plate portion It can be seen that the protruding height of the front surface 8b of the front cover 8 is lower than when 44 is brought into contact with the contact surface 27. As described above, the front cover 8 can easily change the protruding height of the front surface 8b only by reversing the mounting direction with respect to the flange portion 11, and can be used in common for each window frame constituent member 3. It has a highly convenient configuration.

  In actual construction, the front cover 8 is attached to the window frame constituting member 3 for the left side and the corner members 6 and 7 located at both ends thereof, and the window frame constituting member 3 for the right side and corner members 6 and 7 located at both ends thereof. When attaching each of the front covers 8, the two front covers 8 of the same type except for the length are cut so as to adjust only the length, and as shown in FIG. The front surface 8b is attached so that its height is high. At this time, not only the front side of the left and right window frame components 3, but also the front sides of the corner members 6 and 7 positioned above and below the left window frame component 3 and the right window frame component 3, respectively. The length of each front cover 8 is adjusted so as to cover the front cover 8, and the front cover 8 is covered so that the window frame constituting member 3 and the corner members 6 and 7 are integrated. At this time, since both ends of the mounted front cover 8 are in contact with the closing plates 37 of the corner members 6 and 7, the open end portions 52 on both sides of the front cover 8 are completely closed. It is possible to eliminate the gap between the end portions of the eight bumps. In addition, since the closing plate 37 also serves to prevent the front cover 8 from coming off in the vertical direction, the attachment state of the front cover 8 can be reliably maintained.

  On the other hand, when the front cover 8 is attached to the upper window frame component 3 and the lower window frame component 3, respectively, two front covers 8 of the same type as those arranged vertically are provided. Prepare and adjust the length in accordance with the longitudinal length of the flange portion 11 of the window frame component 3, and attach the front surface 8b to a lower height as shown in FIG. 6B. . Both ends of the front cover 8 attached to the upper window frame component member 3 and the lower window frame component member 3 so as to be lower than the protruding height of the front surface 8b of the left and right window frame component members 3, The left and right window frame constituent members 3 and the side portions of the front cover 8 attached to the corner members 6 and 7 are brought into contact with each other. As a result, the open end portions 52 on both sides of the front cover 8 are completely closed, so that the gap at the abutting end portion of the front cover 8 can be eliminated.

  Thus, the front cover 8 covered by the left and right window frame constituent members 3 rather than the front surface 8b of the front cover 8 covered by the upper window frame constituent member 3 and the lower window frame constituent member 3. By attaching the front face 8b so as to protrude toward the bathroom side, the opening end portions 52 of the front cover 8 of the upper window frame constituting member 3 and the lower window frame constituting member 3 become the left and right window frame constituting members 3. It is reliably closed by the side portion of the water, ensuring watertightness and good appearance from inside the bathroom.

  With the above-described configuration, the protrusion height of the front surface 8b of the front cover 8 can be changed simply by reversing the fitting direction of the front cover 8 with respect to the flange portion 11, so that the upper and lower window frames can be changed. By providing the front face 8b of the front cover 8 provided on the left and right window frame constituent members 3 so as to protrude rather than the front cover 8 provided on the constituent member 3, a step is generated and the finish can be finished with a good appearance. Moreover, since it can be used in common for each window frame component 3, the left and right window frame components 3, the upper window frame component 3 and the lower window frame component 3 are respectively front surfaces. It is not necessary to prepare the front cover 8 having a different protruding height of 8b, so that productivity can be improved and manufacturing cost can be reduced. Furthermore, since it is not necessary to distinguish the front cover 8 for each window frame component 3 at the site, assembly work at the site is facilitated and construction efficiency is improved.

  Further, when the front cover 8 is attached to the flange portion 11, either the first locking plate portion 44 or the second locking plate portion 45 of the front cover 8 is brought into contact with the contact surface 27 of the flange portion 11. The protruding height of the front surface 8b of the front cover 8 can be easily changed depending on whether or not. Furthermore, since the protruding height of the front face 8b of the front cover 8 can be adjusted for each window frame constituting member 3 with the same kind of front cover 8, it is provided in consideration of the appearance of the completed window connection frame 1 as described above. can do. In addition, by bringing the first locking plate portion 44 or the second locking plate portion 45 into contact with the contact surface 27 of the flange portion 11, gaps between the window frame constituent members 3 and the front cover 8 can be eliminated. Therefore, the water tightness can be kept good.

  Further, the locking claws 46, 46 provided on the front end side of the first locking plate portion 44 and the second locking plate portion 45 of the front cover 8 are connected to the locking portions 25, 26 of the flange portion 11 and the corner members 6, 6. The front cover for the left and right window frame components 3 and corner members 6, 7, the upper window frame component 3, and the lower window frame component 3 by being locked to the locking portions 48, 49 of FIG. Regardless of the mounting direction of the front cover 8, the mounting state of the front cover 8 can be reliably maintained.

  The opening end 52 of the front cover 8 covered by the upper and lower window frame components 3 is closed by the front cover 8 covered by the left and right window frame components 3, and these left and right window frame components 3. Since the opening end 52 of the front cover 8 is closed by the closing plate 37 provided at one end of the corner members 6, 7, the opening end 52 of each front cover 8 can be reliably closed. In addition, good water tightness can be obtained and appearance can be ensured.

  In addition, as viewed from inside the bathroom, the board portion 10 of both the left-side window frame component member 3 and the right-side window frame component member 3 installed in a vertical posture along the left and right sides of the window opening 102. The lower end portion (the end portion connected to the lower window frame component member 3 at the time of construction) is not perpendicular to the inner wall 101, and the distance from the upper end portion of the window frame component member 3 increases as the distance from the flange portion 11 increases. A notch 9 (see FIG. 2) that gradually inclines at a predetermined angle may be formed from one end on the flange 11 side to the other end so as to be slightly narrowed. In this case, the corner members 6 and 7 positioned at the lower corner portion of the window opening 102 are formed in a shape corresponding to the notch 9 of the window frame constituting member 3 described above. Specifically, as shown in FIGS. 7 and 8, the upper surface 33 of the shaft portion 31 is separated from the closing cap 32 by a predetermined angle along the inclination of the notch 9 from one end to the other end on the closing cap 32 side. The shaft portion 31 is formed so as to be inclined so that the upper surface 33 of the shaft portion 31 is exactly along the notch 9 when assembled. A plurality of connecting pieces 34 inserted into the fitting grooves 15 of the lower window frame component 3 are also arranged in parallel with the inclination of the upper surface 33. With this configuration, the left window frame component member 3 and the right window frame component member 3 are placed in a horizontal posture along the lower side of the window opening 102 via the corner members 6 and 7 having the above-described configuration.
