Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door frame assembly such as a bathroom door.

The frame materials used in conventional door frame assemblies have been made of synthetic resin extrusion molded products, aluminum extrusion molded products, etc. However, extruded products made of synthetic resin have poor strength, and extruded products made of aluminum have poor heat insulation properties. In addition, when assembling these frame materials, connection fittings are attached separately to the outside surface, or tapping holes are provided and connections are made using the tapping holes. In the former case, the appearance was poor, and in the latter case, there were cases in which a sufficient connection could not be achieved by screwing into the tapping hole.

The present invention has been made in view of the above-mentioned points, and the object of the present invention is to provide a material that is lightweight, strong in strength, has excellent heat insulation properties, and has a more subdued appearance compared to metal products. We are on offer to get you a door stile set.

The present invention will be explained in detail below with reference to Examples. 1 is a rectangular cylindrical core material made of metal such as aluminum, and this core material 1 is thickly coated with a foamable synthetic resin such as foamable polyurethane using a crosshead type extrusion molding machine. The frame material A is formed by foaming together with the frame body 2 and covering it with a frame body 2 made of a synthetic resin foam such as urethane foam. When the frame body 2 made of synthetic resin foam is colored with a woody color, it becomes so-called synthetic wood and can give a high-class feel. Further, the surface of the frame main body 2 is coated with a resin such as acrylic resin to protect the surface and to make the surface smooth and glossy.
The upper stile A ₁ and the lower stile are made of the stile material A constructed in this way.
A ₂ , forming a handle side stile A ₃ and a hinge side stile A ₄ ,
Upper stile A ₁ , lower stile A ₂ , handle side stile A ₃ and hinge side stile
A ₄ is assembled into a square frame to form a frame. The connections between the upper stile A ₁ and the handle side stile A ₃ and the hinge side stile A ₄ and the connection between the lower stile A ₂ and the handle side stile A ₃ and the hinge side stile A ₄ are shown in Figure 5 a and b. The connection between the upper stile A ₁ and the handle side vertical stile A ₃ is specifically described as follows. Insert the U-shaped connecting fitting 4 into the core material 1 of the upper stile A ₁ , drill a hole 5 from the side in the stile body 2 of the upper stile A ₁ , and connect the core material 1 and the connecting metal fitting through the hole 5. Attach the connecting fitting 4 by screwing the fixing screw 6 between the side piece 4a of the handle side _A3 , and drill a hole 7 that penetrates into the core material 1 from the side at the upper end of the vertical stile A3 on the handle side. A connecting screw 8 is screwed into the web portion 4b of the connecting fitting 4 from inside the core member 1 through the hole 7 to connect the upper stile _A1 and the handle side vertical stile _A3 . The face plate 9 is inserted into the frame assembly configured as described above, and the edge of the face plate 9 is connected to the upper frame A ₁ ,
It fits into the groove 10 on the inner circumferential side of the lower stile A ₂ , the handle side stile A ₃ , and the hinge side stile A ₄ , and handles 15 are attached to the front and back of the handle side stile A ₃ to make it look like a bathroom door. A door B is formed. This door B is placed in a door frame 11 made of metal or the like, and the vertical stile on the hinge side of the door is
A ₄ and the vertical frame of the door frame 11 are connected by a hinge 12, so that the door B can be opened and closed. Each hinge piece 12a of the hinge 12 is attached with a mounting screw 13, but a core material 14 for attaching the hinge is installed inside the frame material A of the hinge side vertical stile _A4 , as shown in FIG. , the hinge mounting core material 14 is screwed in and firmly attached.

Further, FIG. 7 shows another embodiment of the stile material A used as the hinge-side vertical stile _A4 , in which a core material 14 for attaching the hinge is provided integrally with the core material 1.

As described above, the present invention has an upper stile, a lower stile, a vertical stile on the handle side, and a vertical stile on the hinge side, which are formed by inserting a cylindrical metal core material into the stile body made of synthetic resin foam. Since the door stile assembly is arranged in a square frame shape, it is lightweight due to the synthetic resin foam that makes up the frame body, and of course is strong due to the metal core material. The synthetic resin foam provides excellent heat insulation and allows for a door frame with a more subdued appearance compared to metal ones.Moreover, the exterior is constructed so that the synthetic resin foam is exposed. However, U-shaped connecting metal fittings were inserted into the core material at both ends of the upper and lower stile, and holes were drilled into the sides of the upper and lower stile bodies. Connect the core material and the side pieces of the connecting metal fittings using the inserted connecting screws, and insert them into the core material through the holes that penetrate into the core material from the vertical end sides of the vertical stile on the handle side and the vertical stile on the hinge side. Since the core material and the web part of the connecting metal fitting are connected by the connecting screw, the upper stile, lower stile, handle side vertical stile, and hinge side vertical stile are firmly connected by the metal core part through the connecting metal fitting. Moreover, in this case, by inserting the connecting screw through the hole, the connecting screw is not exposed to the outside, which improves the appearance. The hinge is attached to the hinge mounting core material inside the vertical stile on the hinge side using mounting screws, so the hinge can be mounted securely and firmly even though the synthetic resin foam is exposed on the outside. be.
