The side end 33 (widthwise end) of the glass panel 3 is positioned opposite the side surface 28a of the vertical frame member 28 (vertical frames 21, 22 or mullion 25). Sealant 81 is filled between the side end 33 of the glass panel 3 and the side surface 28a of the vertical frame member 28.

The method for installing the fittings of the first embodiment will be described.
The frame 2 is installed. The glass panel 3 is temporarily fixed inside the frame 2. The first ledge 61 and the second ledge 62 are attached to the horizontal frame member 27 to form the groove 4, and the upper end 31 and the lower end 32 of the glass panel 3 are inserted into the groove 4, so that the side end 33 of the glass panel 3 faces the side surface 28a of the vertical frame member 28. The groove 4 is filled with a sealant, and the glass panel 3 is fixed to the horizontal frame member 27. The sealant 81 is filled between the side end 33 of the glass panel 3 and the side surface 28a of the vertical frame member 28.

In the fitting structure and fitting construction method according to the first embodiment described above, the side surfaces 28a of the vertical frame members 28 (first vertical frame 21, second vertical frame 22, mullions 25) are formed flat and do not have grooves for fixing the glass panels 3, with the side edges 33 of the glass panels 3 positioned opposite each other. In this way, there is no need to form grooves in the vertical frame members 28 or to join components with grooves formed in them, so the widthwise dimension of the vertical frame members 28 can be reduced, improving the design of the fitting 1.

In the fitting structure according to the first embodiment described above, a sealant 81 is filled between the side surface 28a of the vertical frame member 28 and the side edge 33 of the glass panel 3. This seals the gap between the side surface 28a of the vertical frame member 28 and the glass panel 3.

In the fitting structure according to the first embodiment described above, the horizontal frame member 27 has a groove portion 4 into which the upper end portion 31 or lower end portion 32 of the glass panel 3 is inserted, making it easy to secure the glass panel 3 to the horizontal frame member 27.

In the fitting structure according to the first embodiment described above, the side edge 33 of the glass panel 3 is configured to face the side surface 28a of the vertical frame member 28, so the glass panel 3 can be installed at any position in the projection direction relative to the mullions 25. This allows horizontal frame members 27 with grooves 4 at different projection direction positions to be attached to the vertical frame member 28. As a result, the projection direction position of the glass panel 3 can be arranged or adjusted.

Second Embodiment
Next, a second embodiment will be described with reference to the accompanying drawings. Components and parts that are the same as or similar to those in the first embodiment will be designated by the same reference numerals, and descriptions thereof will be omitted. Only configurations different from those in the first embodiment will be described. As shown in Figure 5, in a fitting 1B of a fitting structure according to the second embodiment, an end member 82 is attached to the side edge 33 of a glass panel 3B, and the end member 82 contacts the side surface 28a of the vertical frame member 28. The end member 82 is attached to the entire side edge 33 of the glass panel 3B in the vertical direction. The end member 82 is formed of resin, metal, or the like.

In the second embodiment of the fitting construction method, the end member 82 is attached to the glass panel 3B in advance, and then the glass panel 3B is temporarily fixed to the inside of the frame 2 and fixed to the horizontal frame member 27, as in the first embodiment. In the second embodiment, no sealant is filled between the side edge 33 of the glass panel 3B and the side surface 28a of the vertical frame member 28.

The fitting structure and fitting construction method according to the second embodiment described above achieve the same effects as the first embodiment. In the fitting structure according to the second embodiment, an end member 82 into which the side end 33 of the glass panel 3B is inserted is provided between the side surface 28a of the vertical frame member 28 and the side end 33 of the glass panel 3B, and is in contact with the side surface 28a of the vertical frame member 28. This allows the glass panel 3B to be installed on the frame 2 using a dry construction method, making it easy to construct the fitting 1B.

This disclosure is not limited to the above-described embodiments and may be modified as appropriate without departing from the spirit of the present disclosure. For example, in the above-described embodiments, the frame portion 2 is formed of a pair of vertical frames 21, 22, an upper frame 24, a lower frame 23, a mullion 25, and a transom 26. However, as long as it is formed of vertical frame members 28 and horizontal frame members 27, it may be formed of any necessary components, such as a pair of vertical frames 21, 22, an upper frame 24, and a lower frame 23. Furthermore, in fittings with openings or fittings with shoji screens that open and close the openings, the fitting structures of the above-described embodiments may be employed in the portions adjacent to the openings in the vertical or widthwise directions. The panel body provided inside the frame portion 2 may be a plate-shaped member other than the glass panel 3.

In the above embodiment, a sealing material 81 and an end member 82 are provided between the side surface 28a of the vertical frame member 28 and the side end portion 33 of the glass panel 3, but a member instead of the sealing material 81 or the end member 82 may be provided, or members such as the sealing material 81 or the end member 82 may not be provided between the side surface 28a of the vertical frame member 28 and the side end portion 33 of the glass panel 3.
In the above embodiment, the upper end 31 and lower end 32 of the glass panel 3 are inserted into the groove portion 4 and fixed, but the fixing portion that fixes the upper end 31 and lower end 32 of the glass panel 3 to the horizontal frame material 27 may be in a form other than the groove portion 4.

In the above embodiment, the groove 4 is formed between the first ledge 61 and the second ledge 62, which are attached to the top or bottom of the main body (the transom body 261, the upper frame body 241, and the lower frame body 231) of the horizontal frame material 27 at a distance in the projection direction. Alternatively, as in the fitting 1C shown in Figure 6, a facing surface 41 facing the projection direction may be formed on the transom body 261C of the transom 26C and the lower frame body 231C of the lower frame 23C, and a ledge 6C may be attached to the transom body 261C and the lower frame body 231C at a distance in the projection direction from this facing surface 41, forming a groove 4C between the facing surface 41 and the ledge 6C, into which the lower end 32 of the glass panel 3 is inserted. The groove 4 into which the upper end 31 of the glass panel 3 is inserted may be formed as described above.

In the above embodiment, the groove 4 is formed by the main body of the horizontal frame member 27 and the batten 6. However, as shown in FIG. 6, the groove 4D may be formed directly in the upper frame main body 241C of the upper frame 24C or the batten main body 261C of the batten 26C without using a batten, as in the case of groove 4D formed on the lower side of the upper frame 24 or the batten 26. As shown in FIG. 6, when the batten 6C is provided on the horizontal frame member 27C, the upper surface 6a of the batten 6C attached to the main body of the horizontal frame member 27C may be set to the same height as the upper surface 27b of the main body of the horizontal frame member 27C so that the batten 6C does not protrude above the main body of the horizontal frame member 27C. The upper surface 6a of the batten 6C attached to the main body of the horizontal frame member 27C may be set to be lower than the upper surface 27b of the main body of the horizontal frame member 27C so that the batten 6C does not protrude above the main body of the horizontal frame member 27C. When the batten 6 is attached below the main body of the horizontal frame member 27, the underside of the batten 6 may be at the same height as the underside of the main body of the horizontal frame member 27 or higher than the underside of the main body of the horizontal frame member 27, so that the batten 6 does not protrude downward from the main body of the horizontal frame member 27.

In the above embodiment, the mullion 25 and the mullion 26 have the same dimensions in the projection direction, but as in the fitting 1C shown in Figure 6, the projection dimension of the mullion 26C may be set smaller than the projection dimension of the mullion 25. Also, the projection dimension of the mullion 25 may be set smaller than the projection dimension of the mullion 26. In the above embodiment, the fitting 1 is fixed to the structure 11, but it does not have to be fixed to the structure 11.
