Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a door having an assembling portion, such as an entrance door.

[0002]

[Prior art]

 As an example of a door having a combining section, there is a device disclosed in Japanese Utility Model Publication No. 4-33352 or Japanese Utility Model Publication No. 5-556. The former idea is that between the outer and inner face plates, which are constructed by interposing a frame, there is a mounting part that is received from the door end face and a summing part that protrudes outside the door and blinds the summing part. The bent edge is made of the same material as the face plate, and is fitted inside the face plate to close the door end face. Is. In the latter device, a steel sheet surface plate is stretched over the door body, and the summing edge provided at the door end is formed by coating a core material made of steel material with the same type of steel sheet as the surface sheet. It is a thing.

[0003]

[Problems to be solved by the device]

 In the invention disclosed in Japanese Utility Model Publication No. 4-33352, the summing edge is configured to be attached by a side edge between the bent sides of the surface plate with a certain amount of elastic restoring force. Although not described, it is considered that it is composed of a material that is almost the same as that of the face plate in view of the drawings and the point that it has an elastic restoring force. For this reason, the free end surface of the assembling portion and the door is fragile and may be deformed by long-term use or damaged by impact or the like.

Further, in the invention disclosed in Japanese Utility Model Publication No. 5-556, the core material made of steel is covered with a steel plate of the same kind as the surface plate to form the assembly edge. It becomes heavy and unbalanced as a whole, and problems such as the hinge being damaged and the door construction being bad due to long-term use occur.

The present invention has been made to solve the above-mentioned problems, and the assembling portion and the end surface of the door are strong, and there is no risk of deformation due to long-term use or damage due to impact, etc. The purpose of the present invention is to obtain a door with a fitting part that is well balanced as a whole because of its light weight, and does not cause hinges or the door construction to deteriorate even after long-term use. Is.
