The end panel 8 has a flat surface 8C. The end panel 8 has a third claw 8E extending vertically on the back surface 8D. The third claw 8E is formed to protrude from the back surface 8D. With the above configuration, the first frame member 3 and the second frame member 6 are combined to form a hollow mullion 2. The mullion 2 is formed as a cylindrical body with a rectangular cross section. In the mullion 2, the third claw 5E of the first frame member 3 engages with the first claw 7E of the second frame member 6. The third claw 8E of the second frame member 6 engages with the first claw 4E of the first frame member 3.

The first frame member 3 and the second frame member 6 are fixed together by screws S fastening the vertical plate 4 of the first frame member 3 and the second claw portion 7F of the second frame member 6 together. The second claw portion 4F of the first frame member 3 abuts the back surface 7D of the second frame member 6, and the second claw portion 7F of the second frame member 6 abuts the back surface 4D of the first frame member 3. A ledge 10 is fixed to each of the vertical plate 4 of the first frame member 3 and the vertical plate 7 of the second frame member 6. The second claw portions 4F, 7F improve the bending rigidity of the mullions 2 and prevent buckling of the mullions 2 against the load of the glass plate G that is received by the ledge 10.

The battens 10 are components for securing the glass panes G. The battens 10 are attached to the vertical frame 50 facing the first frame member 3. The battens 10 are attached to the vertical frame 50 facing the second frame member 6. The battens 10 attached to the first frame member 3 and the battens 10 attached to the second frame member 6 are fixed so as to be symmetrical with respect to the mullion 2. The battens 10 are formed to extend in the vertical direction on other components such as the first frame member 3, the second frame member 6, and the vertical frame 50.

The ridge 10 is a hollow member formed by extruding aluminum. The surface of the ridge 10 is pre-painted or anodized. In addition to being painted or anodized, the surface of the ridge 10 may also be lapped. The ridge 10 is formed into a cylindrical body with a rectangular cross section. The ridge 10 is formed to clamp and secure the edge of the glass sheet G. The ridge 10 supports the edge of the glass sheet G at a distance from the first frame member 3 and the second frame member 6 (mullions 2).

The ridge 10 has a recessed groove 10A that accommodates the edge of the glass plate G. The ridge 10 comprises a main body 11 that is fixed to another component, and a lid 12 that can be attached and detached to the main body 11. The ridge 10 is fixed to the mullion 2, for example, so that the lid 12 is positioned on the indoor side. The main body 11 has an installation surface 11A that abuts against another component. The installation surface 11A has screw holes 11B formed therein for screwing to another component. Multiple screw holes 11B are formed in the vertical direction. The ridge 10 is fixed to another component via the screw holes 11B using screws S0 and S1.

A first arm 11C is formed perpendicular to the installation surface 11A. The first arm 11C is one of the members that clamps the edge of the glass plate G. The main body 11 is formed with a first claw 11D and a second claw 11E for engaging the lid 12.

The lid 12 is fitted into the main body 11. The lid 12 has a second arm 12A that faces the first arm 11C. A fixing surface 12B is formed at the base of the second arm 12A in a direction approximately perpendicular to the second arm 12A. The fixing surface 12B has a third claw 12C that engages with the first claw 11D of the main body 11, and a fourth claw 12D that engages with the second claw 11E of the main body 11. The glass plate G is temporarily fixed to the main body 11 when the lid 12 is removed.

A backup material H is fitted into the main body 11 to form the joint bottom so as to clamp the edge of the glass sheet G. A lid 12 is attached to the main body 11. When the lid 12 is attached to the main body 11, a groove 10A is formed. A sealant C is filled into the gap between the groove 10A and the glass sheet G. The edge of the glass sheet G is clamped between the first arm 11C and the second arm 12A via the sealant C.

The batten 10 is fixed to the vertical frame 50 with screws S1. The vertical frame 50 is fixed to a fixing member J installed in the wall W with tap screws S2. The lid portion 12 is fitted into the main body portion 11 without the use of screws, simplifying construction, shortening the construction period, and improving the design.

Before the lid 12 is attached, the bezel 10 is fixed to other components using screws S0 and S1 from inside the main body 11. After the lid 12 is attached, the screws S0 and S1 are concealed inside the bezel 10, improving the design. When the lid 12 is removed, the groove 10A is exposed, making it easy to attach the glass sheet G. With the lid 12 removed, the glass sheet G can be attached from the interior side of the room.

Next, we will explain the crossbeams 30. The crossbeams 30 are members that are installed horizontally on both sides of the mullions 2 to the vertical frames 50 (see Figure 1). The ends of the crossbeams 30 are fixed to the mullions 2 and the vertical frames 50 with screws (not shown) or the like.

As shown in Figure 4, the mullion 30 has three screw claws 35 formed on it in a side view, each with a pair of protrusions that protrude inward. The following description will be given from a side view. The screw claws 35 are formed so that the pair of protrusions can grip a screw. Screws are threaded into the screw claws 35 of the mullion 30 from the back surface 4D side through screw holes (not shown) formed in the first frame member 3, and from the back surface 4D side through screw holes (not shown) formed in the second frame member 6, thereby fixing the mullion 30 to the mullion 2. Similarly, the mullion 30 is also fixed to the vertical frame 50 using screws. The screws are concealed inside the mullion 30, the mullion 2, and the vertical frame 50, improving the design of the fitting 1.

The transom 30 is a hollow member formed by extruding aluminum. The surface of the transom 30 is pre-painted or anodized. In addition to being painted or anodized, the surface of the transom 30 may also be wrapped. The transom 30 comprises a main body 31 and a lid 32. The side with the lid 32 faces the interior. The transom 30 is formed as a cylindrical body with a rectangular cross section when viewed from the side. A groove 31A is formed on the upper surface of the main body 31 so as to hold the lower end of the glass sheet G. A groove 31B is formed on the lower surface of the main body 31 so as to hold the upper end of the glass sheet G.

A partition plate 31C is formed inside the main body 31, separating the groove portion 31A from the groove portion 31B. A support member K that supports the lower end of the glass plate G is fitted onto the upper surface of the partition plate 31C. The main body 31 is formed with a first claw portion 31D and a second claw portion 31E for engaging the lid portion 32. The lid portion 32 is formed with a third claw portion 32A that engages with the first claw portion 31D and a fourth claw portion 32B that engages with the second claw portion 31E.

When installing the glass sheet G in the groove portion 31A, the lid portion 32 is removed and the glass sheet G is temporarily fixed to the main body portion 31. The lower end of the glass sheet G is placed on the support member K. A backup material H is fitted into the main body portion 31 to form the joint bottom and clamp the edge of the glass sheet G. The lid portion 32 is attached to the main body portion 31.

The lid 32 is fitted into the main body 31 without the use of screws, simplifying installation, shortening construction time, and improving design. When the lid 32 is removed, the groove 31A is exposed, facilitating installation of the glass pane G. With the lid 32 removed, the glass pane G can be installed from the interior side.

A glass sheet G is attached to the transom 30 with the lid 32 removed. Sealant C is filled into the gap between the groove 31A and the glass sheet G. The lower end of the glass sheet G is clamped and fixed in place by the groove 31A via the sealant C. The upper end of the glass sheet G is fixed to the horizontal frame 70, which will be described later.

Another glass sheet G, attached below the glass sheet G supported in groove 31A, is temporarily fixed to the main body 31 with its upper end inserted into groove 31B. The glass sheet G is temporarily fixed with its upper end sandwiched between backup material H. Sealant C is filled into the gap between groove 31B and the glass sheet G. The upper end of the glass sheet G is sandwiched and fixed in place by groove 31B via sealant C. The lower end of the glass sheet G is fixed to the horizontal frame 80, which will be described later.

Next, we will explain the horizontal frame 70. The horizontal frame 70 is a hollow member that is fixed to the upper edge of a rectangular opening in a building. The horizontal frame 70 is formed as a cylindrical body with a rectangular cross section. The horizontal frame 70 is formed, for example, with the same width as the mullion 2. A groove 71 is formed on the underside of the horizontal frame 70. A screw hole 71B is formed in a partition plate 71A that separates the space in which the groove 71 is formed. The horizontal frame 70 is fixed to a fixing member J provided in the wall W via a tap screw S2 through the screw hole 71B.

Back-up material H is fitted into groove 71. The upper end of glass sheet G is inserted into groove 71 and temporarily fixed while being clamped between backup material H. Sealant C is filled into the gap between groove 71 and glass sheet G. The upper end of glass sheet G is clamped and fixed in place by groove 71 via sealant C.

Next, the horizontal frame 80 will be described. The horizontal frame 80 is a hollow member that is fixed to the bottom edge of a rectangular opening in a building. The horizontal frame 80 is formed as a cylindrical body with a rectangular cross section. The horizontal frame 80 is formed, for example, with the same width as the mullion 2. A groove 81 is formed on the upper surface of the horizontal frame 80. A partition plate 81A that separates the space in which the groove 81 is formed has a screw hole 81B formed in it. The horizontal frame 80 is fixed to a fixing member J provided in the wall W or floor surface with a tap screw S2 via the screw hole 81B. The horizontal frame 80 comprises a main body 82 and a lid 83. The side with the lid 83 faces the room side.

A support member K that supports the lower end of the glass plate G is fitted onto the upper surface of the partition plate 31C. The main body 82 is formed with a first claw 82A and a second claw 82B for engaging the lid portion 83. The lid portion 83 is formed with a third claw 83A that engages with the first claw 82A and a fourth claw 83B that engages with the second claw 82B. When attaching the glass plate G to the groove portion 81, it is temporarily fastened to the main body 82 with the lid portion 83 removed. The lower end of the glass plate G is placed on the support member K.

Back-up material H is fitted into the main body 82 to form the joint bottom so as to clamp the edge of the glass sheet G. A lid 83 is attached to the main body 82. Sealant C is filled into the gap between the groove 81 and the glass sheet G. The lower edge of the glass sheet G is clamped and fixed by the groove 81 via the sealant C. The lid 83 is fitted into the main body 82 without the use of screws, simplifying construction, shortening construction time, and improving design. When the lid 83 is removed, the groove 81 is exposed, making it easy to install the glass sheet G. With the lid 83 removed, the glass sheet G can be installed from the inside of the room.

Next, we will explain how to install building fixture 1.

As shown in Figure 5, with the lid portions 12, 32, and 83 removed, the first frame body is formed by assembling the components including the first frame member 3 with exposed grooves 10A, 31A, and 81, the batten 10, the transom 30, a pair of vertical frames 50, and horizontal frames 70 and 80 (step S10). With the lid portions 12, 32, and 83 removed, the second frame body is formed by assembling the components including the second frame member 6 with exposed grooves 10A, 31A, and 81, the batten 10, the transom 30, a pair of vertical frames 50, and horizontal frames 70 and 80 (step S12).

The first frame member 3 and the second frame member 6 are fixed together to form the mullions 2, and the lattice-shaped frame body with the mullions 2 formed on it is fixed in place on the building (step S14). The upper end of the glass sheet G is inserted into the grooves 71 and 31B, while being temporarily fixed in the exposed grooves 10A, 31A, and 81, and is fitted into each of the lattices formed on the frame body and temporarily fixed in place (step S16).

The lids 12, 32, and 83 are attached to the batten 10, transom 30, and horizontal frame 80, respectively, and grooves 10A, 31A, and 81 are formed (step S18). The gaps between the grooves 10A, 31A, 31B, 71, and 81 and the glass sheet G are filled with sealant C to secure the glass sheet G (step S20).

As described above, with the fitting 1, the mullions 2 and battens 10 are constructed as separate bodies, which allows the edges of the glass panes G to be supported at a distance from the mullions, resulting in a slim mullions 2 when viewed from the front, improving design. With the fitting 1, by providing lids 12, 32, and 83 on the battens 10, transom 30, and horizontal frame 80, fixing screws and the like can be concealed within the components without being exposed to the outside, improving design. With the fitting 1, the frame is formed by assembling pre-assembled and painted components to some extent on-site with screws, etc., simplifying construction and significantly shortening the construction period.

Second Embodiment
6 and 7, the fitting 1A according to the second embodiment comprises a mullion 2, a pair of battens 100, and a transom 300. Unlike the integrally formed battens 10 of the first embodiment, the fitting 1A comprises a pair of battens 100 that are formed separately so as to sandwich a glass sheet G. The fitting 1A uses a mullion 2 and a pair of battens 100 instead of vertical frames 50 as frame materials on both the left and right sides.

Hereinafter, the same names and symbols will be used for the same components as in the first embodiment, and duplicate explanations will be omitted where appropriate. Below, a plan view will be described. The flange 100 is formed into a cylindrical body with a rectangular cross section. The flange 100 has a female thread 102 formed on the mounting surface side of the first frame member 3 and the second frame member 6. The flange 100 is fixed with screws S3 from the back surface 4D side of the first frame member 3 and the back surface 7D side of the second frame member 6. A pair of flanges 100 are arranged opposite each other at a distance to form a groove portion 100A.

As shown in Figure 8, the transom 300 comprises a main body 301 and a pair of ridges 310 on the upper surface of the main body 301. A side view will be described below. The main body 301 is formed as a cylindrical body with a rectangular cross section. The upper and lower surfaces of the main body 301 are formed with first claws 302 and second claws 303 that protrude outward from the upper and lower surfaces and bend toward each other. The main body 301 is formed, for example, so that its vertical width is the same as the width of the mullion 2 when viewed from the front.

The flange 310 is formed like a rail with a U-section, with a rectangular cross section partially open. The ends of the flange 310 are formed with a third claw 311 that engages with the first claw 302 and a fourth claw 312 that engages with the second claw 303. The flange 310 is formed so that it can be detachably fitted into the main body 301. The flange 310 is formed with the same width as the flange 100. A pair of flanges 310 are fitted into the main body 301 so that they face each other and are spaced apart, forming a groove 315. For example, when the indoor-side flange 310 of the pair of flanges 310 is removed, the groove 315 is exposed, and when the flange 310 is attached, the groove 315 is formed. Therefore, the glass pane G is attached with the outdoor-side flange 310 attached and the indoor-side flange 310 removed.

A horizontal frame 320 is attached to the top of the fitting 1A. The horizontal frame 320 comprises a main body 321 and a pair of battens 310. The main body 321 is formed in the same shape as the top surface of the main body 301 of the transom 300. The main body 321 is fixed to the installation target, such as the ceiling R, via fixing member J using tap screws S2 or the like. The pair of battens 310 are fitted into the main body 321 so that they face each other and are spaced apart, forming grooves 316.

A horizontal frame 320, which is the upside-down version of the horizontal frame 320 attached to the upper part, is attached to the lower part of the fitting 1A. The main body 321 is fixed to the installation target, such as the floor E, using tap screws S2 or the like. The tap screws S2 are concealed by a pair of battens 310.

The fitting 1A not only forms a thin mullion 2 when viewed from the front, but also allows the transom 300 and horizontal frame 320 to be formed thin, improving the design. The fitting 1A uses a pair of detachable battens 310, which allows fixing screws and the like to be concealed inside the component without being exposed to the outside, improving the design.

[Third embodiment]
As shown in Figure 9, in fitting 1B, part of the glass plate G attached to fitting 1A is replaced with plate B. Fitting 1B comprises a mullion 2, a ledge 350, and a fixing member 360. Fixing member 360 is formed with an L-shaped cross section. Fixing member 360 has a bottom 362 with a screw hole 361 formed therein and a receiving portion 363 bent in a direction perpendicular to the bottom.

A female screw M is formed at the installation position of the mullion 2 at a position corresponding to the screw hole 361. The fixing member 360 has its bottom 362 fixed to the side of the mullion 2 with a screw S1. The receiving portion 363 is fixed so that it is flush with the end plate 8 of the mullion 2, for example. The receiving portion 363 supports the end of one end face B1 of the plate B.

The flange 350 supports the end of the other end surface B2 of the plate B. The flange 350 is formed as a cylindrical body with a rectangular cross section. The flange 350 comprises a main body 351 and a lid 352. The main body 351 is formed like a rail with a U-section, with one portion of the rectangular cross section open. A pair of claws 351A that protrude inward are formed on both ends of the main body 351. The lid 352 is formed to close the opening of the main body 351. The lid 352 has a pair of claws 352A that protrude outward and bend on the back side that engages with the pair of claws 351A.

The main body 351 has a screw hole 351C formed in the bottom 351B facing the lid 352. A female screw M is formed at the installation position of the mullion 2 in a position corresponding to the screw hole 351C. The bottom 351B of the main body 351 is fixed to the side of the mullion 2 with a screw S1 inserted through the opening. The lid 352 is then fitted into the opening of the main body 351.

As shown in Figure 10, when viewed from the side, plate B has its upper end fixed to the horizontal frame 320 (see Figure 8) and its lower end fixed to the horizontal frame 70 (see Figure 4). The groove 71 of the horizontal frame 70 is closed by a lid 77. Plate B has its upper and lower ends fixed by a ledge 350.

With fitting 1B, glass plate G can be replaced with plate B, allowing for a wide variety of designs to be created for the installation target.

The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified or replaced as appropriate. For example, the glass plate G may be made of other plate-like materials such as acrylic or polycarbonate.
