  The vertical frames 13, 13 on both sides of the frame member 10 are provided with grooved window receiving portions 13 </ b> A capable of receiving substantially the entire vertical rod 23 of the both window members 20. Specifically, as shown in FIG. 4 and FIG. 5, the vertical frame 13 is a groove-shaped body having a substantially U-shaped cross section that opens to the side. The dimensions are sufficient to be received in a stacked state in the thickness direction. As shown in FIG. 5, the depth of the window receiving portion 13 </ b> A is such that when the window member 20 is built in the frame member 10 and in the closed state, substantially the entire width direction of the vertical rod 23 enters. . On the inner bottom surface of the vertical frame 13 (window receiving portion 13A), as described above, the vertical protrusion 13a that engages with the concave groove 23d of the vertical rod 23 is provided. In addition, a flange 13 c protruding to the outdoor side 6 is provided at the tip of the groove wall 13 b on the outdoor side 6 of the vertical frame 13.

  The upper frame 11 has the window receiving portion 11A as described above. Specifically, as shown in FIGS. 4 and 6, the upper frame 11 is a groove-shaped body having a substantially U-shaped cross section that opens downward, and the groove width is thicker than the upper collar 21 of the both window members 20. It is dimensioned to be received in a stacked state in the vertical direction. As shown in FIG. 6, the depth of the window receiving portion 11 </ b> A is set such that substantially the entire width of the upper collar 21 enters when the window member 20 is built on the frame member 10. Parallel guide protrusions 11ab on which two window members 20 slide are provided on the inner bottom surface of the upper frame 11 (the window receiving portion 11A).

  The upper frame 11 is configured by attaching a divided frame member 11b with a flange 11ba to the lower end surface of the groove wall 11aa on the indoor side 5 of the frame main body 11a. The divided frame member 11b may be detachably attached using, for example, a bolt or a buried nut. With the divided frame member 11 b attached, substantially the entire height of the upper collar 21 of the window member 20 is hidden from the indoor side 5. Further, a flange 11ac protruding to the outdoor side 6 is provided at the lower end of the groove wall 11aa on the outdoor side 6 of the upper frame 11.

  The lower frame 12 has the window receiving portion 12A as described above. Specifically, as shown in FIGS. 4 and 6, the lower frame 12 is a groove-shaped body having a substantially U-shaped cross-section opened upward, and the groove width is thicker than the lower collar 22 of the both window members 20. It is dimensioned to be received in a stacked state in the vertical direction. As shown in FIG. 6, the depth of the window receiving portion 12 </ b> A is set such that substantially the entire height of the lower eyelid 22 enters the window member 20 in a state where the window member 20 is built on the frame member 10. In addition, on the inner bottom surface 12b of the lower frame 12 (window receiving portion 12A), four parallel and equally spaced rails 12c are provided for the two window members 20 to slide. The inner bottom surface 12b is provided with a water gradient having an inclination angle of about 2 degrees in order to allow the water accumulated in the window receiving portion 12A to flow to the outdoor side 6, and in the vicinity of the corner on the downstream side (outdoor side 6). Are provided with a plurality of drain holes 12d.

  A flange 12e to which a wide cover 16 (outdoor cover) is attached is formed at the upper end of the groove wall 12a on the outdoor side 6 of the lower frame 12. A narrow cover 15 (indoor cover) is attached to the upper end of the other groove wall 12a of the lower frame 12. In order to make the covers 15 and 16 easy to attach and detach, it is desirable that they are attached with bolts and embedded nuts, or fitted to the upper frame 11 and the lower frame 12. In particular, when it is fitted and attached, the appearance is improved.

  As shown in FIG. 5, the covers 15 and 16 are flat plates, and are arranged so as to be sandwiched between the vertical frames 13 and 13, and the engagement pieces 15 a and 16 a protruding sideways are window receiving portions of the vertical frame 13. It is attached to the lower frame 12 with a fixing tool in a state of entering into 13A. Further, as shown in FIG. 6, the covers 15 and 16 are attached so as to cover part of the opening of the window receiving portion 12A of the lower frame 12 on the groove wall 12a side from above. That is, the covers 15 and 16 are provided so as to protrude from the respective opening edges on both sides in the groove width direction of the window receiving portion 12A of the lower frame 12, and on the upper side of the lower collar 22 of each window member 20. Installed to be arranged.

  As described above, the frame members 11, 12, and 13 constituting the frame member 10 are provided with the window receiving portions 11 </ b> A, 12 </ b> A, and 13 </ b> A that receive substantially the entire flanges 21, 22, and 23 of the window member 20. Therefore, it is possible to avoid the ridges 21, 22, and 23 being largely exposed on the inner peripheral side of the frame member 10 on both the indoor side 5 and the outdoor side 6. As a result, a clean impression can be created and the appearance can be improved. The window device 1 has a good appearance if it has at least the window receiving portion 11A of the upper frame 11 and the window receiving portion 12A of the lower frame 12, but also has the window receiving portion 13A of the vertical frame 13. The appearance when the window is closed is much better (see FIG. 2).

  Further, as described above, the frame member 10 is provided with the flange portions 11ac, 12e, 13c, and 13c corresponding to the upper frame 11, the lower frame 12, and the vertical frame 13, which are provided on the outdoor side 6 on the exterior wall. It protrudes larger than the thickness of the material 60 (see FIGS. 5 and 6). The opening edges of the exterior wall material 50 are in contact with the back surfaces of the flanges 11ac, 12e, 13c, and 13c, and the structure prevents the rainwater from entering the interior of the exterior wall material 50 from entering the room. . The flanges 11ac, 12e, 13c, and 13c can also serve as positioning portions when the exterior wall material 50 is disposed.

  Since it is such a window device mounting structure, as shown in FIG. 2, the end portions of the flanges 11ac, 12e, 13c and the cover 16 are exposed inside the opening 51 of the exterior wall member 50, but the frame member. 10 is covered with the exterior wall material 50. Therefore, there is almost no exposure of the ridges other than the central vertical ridge 23 and the frame member 10 on the inner peripheral side of the outer peripheral wall member 50, and a large light-transmitting region can be taken.

  Further, since each ridge is embedded in the window receiving portions 11A, 12A, and 13A, the ridge becomes a thermal bridge portion by using the light-transmitting plate 24 with good heat insulation as in this embodiment. This can be suppressed.

  Further, since the window receiving portions 11A, 12A, and 13A have a sufficient groove width to receive two ridges in the thickness direction, the upper frame 11, the lower frame 12, and the vertical frame 13 are in the groove width direction. It has a large opening. As for the lower frame 12, since the openings 15 and 16 are provided so that the opening width is narrower than the groove wall 12a side, exposure of a large opening is avoided, so that dust, dust and rainwater can enter from the opening. It can be avoided as much as possible.

  Further, in the present embodiment, the covers 15 and 16 are disposed closer to the light transmitting plate 24 in order to reduce the opening width dimension of the window receiving portion 12A of the lower frame 12. As described above, the vertical groove 23 is formed with the receiving groove 23b for avoiding the interference with the covers 15 and 16, so that the covers 15 and 16 can be received. For this reason, in order to receive the covers 15 and 16, the dimension along the wall thickness direction of the vertical rod 23 can be made larger than the size along the wall thickness direction of the vertical rod 23, which is strong. It becomes. As shown in FIG. 6, the lower surface of the receiving groove 23b is substantially flush with the upper surface of the lower collar 22, so that the covers 15 and 16 can be received smoothly.

  In order to narrow the opening width by installing the covers 15 and 16, it is desirable to reduce the gap dimension in the thickness direction between the light transmitting plates 24 and 24. Therefore, in this embodiment, the translucent plate 24 is provided at a position offset in the thickness direction of the lower collar 22 so as to be arranged at a position closer to the approximate center position of the groove width of the window receiving portion 12A of the lower frame 12. It has been.

  The mounting structure of the window device is a structure in which the exterior wall member 50 is arranged on the outdoor side 6 of the window frame base 30 as described above. Further, as shown in FIG. 1, the mounting structure of the window device is an earthquake-resistant frame fixed to the outdoor side 6 of the window frame base 30 so as to surround the opening of the window frame base 30 in order to install the exterior wall material 50. It is desirable to have 40. You may make it include such an exterior wall material 50 and the earthquake-resistant frame 40 as a member of the window apparatus 1. FIG.

  The seismic frame 40 may be constructed by assembling a lip groove steel (C channel material) into a frame-like body made up of upper, lower, and both side frames as shown in FIG. The seismic frame 40 is arranged so that the groove inner surface of the C channel material faces the outdoor direction. Further, the lower frame 41 of the earthquake-resistant frame 40 is provided with drain holes 42, 42 penetrating in the vertical direction. In the illustrated example, the drain holes 42 are provided in upper and lower groove walls 41a that are arranged substantially horizontally.

  Thus, since the earthquake-resistant frame 40 is provided, the earthquake resistance in the opening part of a window can be improved. Moreover, what is necessary is just to provide the earthquake-resistant flame | frame 40 using the trunk edge space to which the exterior wall material around a window opening part is fixed. By doing so, the seismic frame 40 can be functioned as a trunk edge, and the appearance can be remarkably improved compared to a structure in which the seismic reinforcement frame is fixed to the outer wall retrospectively so as to surround the window opening. .

  Further, since the seismic frame 40 is covered with the exterior wall material 50, there is no possibility that the appearance will be deteriorated. Furthermore, the seismic frame 40 is drained to the outside by providing a drain pipe so as to communicate from the drain hole 12d of the lower frame 12 through the drain hole 42 on the seismic frame 40 to the lower drain hole 42. It can be used as a drainage facility. Note that a waterproof sheet may be provided between the window frame base 30 and the earthquake-resistant frame 40 to enhance the waterproof property.

  Since the outdoor side 6 has a structure covered with the exterior wall material 50 in this way, the aesthetic appearance of the outdoor side 6 can be improved as described above. Further, as shown in FIGS. 5 and 6, the indoor side 5 may have a window device mounting structure in which an interior material 55 is disposed so as to cover a part of the frame member 10 and further the window frame base 30. . In this way, the frame member 10 becomes less conspicuous even on the indoor side 5, and the appearance can be improved. The interior material 55 is not limited to a wall base material such as a plaster board or a wall base material such as a discarded laminated plywood, and may be a floor material arranged to cover the lower frame 12.

  The indoor side 5 of the frame member 10 is also provided with a flange portion 11ba (provided on the divided frame member 11b) of the upper frame 11 and a flange portion 13c of the vertical frame 13, and the interior material 55 abuts against these back surfaces. . On the indoor side 5, the lower frame 12 has no flange portion, and an interior material 55 made of a floor material is provided on the outer surface of the groove wall 12 a so as to be flush with the groove wall 12 a.

  The window frame substrate 30 is not limited to the one assembled according to the shape and size of the frame member 10 at the construction site, and the window device 1 may have a configuration including the window frame substrate 30. By doing so, the frame member 10 and the window frame base | substrate 30 can be assembled | attached in a factory etc. and the improvement of workability | operativity can be aimed at.

  Next, a procedure for attaching and detaching the window member 20 will be described with reference to FIG. As shown in FIG. 7, the window member 20 is removed to the indoor side 5.

First, the window member 20 on the indoor side 5 is moved to, for example, a substantially central position in the opening width direction so that the vertical gutter 23 is exposed from the window receiving portion 13A of the vertical frame 13.
Next, the cover 15 (indoor cover) and the divided frame member 11b are removed (see FIG. 7A).
Further, the auxiliary upper collar 21c of the window member 20 on the indoor side 5 is removed (see FIG. 7A). In the state where the window member 20 is built on the frame member 10, the two auxiliary upper rods 21c and 21c (see FIG. 3) may be slid and detached as described above.
Then, the door member 22b on the indoor side 5 is used as a fulcrum, and the window member 20 may be removed while being rotated so as to be tilted to the indoor side 5 (see FIG. 7B).
Similarly, the window member 20 on the outdoor side 6 can be similarly removed to the indoor side 5 by detaching the auxiliary upper bar 21c.

  In the window member 20, the upper rod 21 and the lower rod 22 are deeply inserted into the upper and lower window receiving portions 11A and 12A of the frame member 10, but the window member can be easily removed by removing the three detachable members as described above. 20 can be removed and attached in reverse order.

  In the present embodiment, the groove wall 11aa on the outdoor side 6 of the upper frame 11 (frame body 11a) is not vertically divided, and a window receiving portion is provided at the upper end of the groove wall 12a on the outdoor side 6 of the lower frame 12. Since the eaves part 12e which narrowed the opening width of 12A is formed, the window member 20 cannot be removed to the outdoor side 6. FIG. Of course, the groove wall 11aa on the outdoor side 6 of the upper frame 11 (frame body 11a) is divided into the upper and lower sides in the same manner as the groove wall 11aa on the indoor side 5, and the opening width is widened to remove the window member 20 to the outdoor side 6. It goes without saying that you can do it.
