[0002]

2. Description of the Related Art As a door body, upper and lower horizontal rails and left and right vertical rails are assembled in a frame shape, and the horizontal rails are formed by separately forming a horizontal rail body and a horizontal frame member. And a vertical frame portion are integrally formed, and a door body (referred to as the former) in which a panel, for example, a glass panel is mounted in a section defined by a frame portion (horizontal frame member and vertical frame portion) is known. (The actual opening 55-178
See No. 592. In addition, as for the horizontal rail, the horizontal rail main body and the horizontal frame part are integrally formed.

[0004] Since any of the above-mentioned doors is provided with a frame on which a glass panel is mounted, it is excellent in decorativeness, and a solid feeling and a high-class feeling can be obtained.

[0005]

However, in the latter door body, the number of parts is large.
This requires as many as 24 screws and screws, which requires a lot of time and labor for cutting and assembling the shaped material, and also increases the cost. If the frame is not used, the cost can be reduced, but the decorativeness is lacking. In the former door body, the ends of the horizontal frame member and the vertical frame portion are connected to each other by four.
Since it is configured to cut at 5 degrees and abut each other, not only the cutting process is difficult, but also a gap is generated between the ends, light leaks, or a horizontal frame member depending on the accuracy of the cutting process. When the ends of the vertical frame interfere with each other and the vertical bar main body of the vertical bar is fastened to the end of the horizontal bar with screws and joined, poor tightening is likely to occur, resulting in poor assemblability and strength. .

Accordingly, the present invention has been made to solve the above-mentioned problems, and can reduce the cost while maintaining the decorativeness, and can fix the vertical beam main body of the vertical beam to the end of the horizontal beam with a fixing tool. An object of the present invention is to provide a door body that can be tightly tightened and can be assembled and improved in strength when being joined.

In particular, in the door body 1, the vertical bar 3 is formed by integrally forming the vertical bar body 4 and the vertical frame portion 5, and the middle vertical bar 9 is also formed by integrally forming the vertical frame portion 10 on both sides. In addition, since no horizontal frame portion or horizontal frame member is employed, the number of components can be significantly reduced as compared with a conventional door body. By the way, in the case of the door body 1 of the above-described embodiment, it is sufficient to use five shape members and eight screws.

Therefore, since there is no trouble in cutting or assembling the shaped material, not only the shaped material cost but also the processing cost and the assembling cost can be reduced. Further, since the vertical frame portion 5 is employed, decorativeness or design can be secured. That is, according to the door body 1, cost reduction can be achieved while maintaining decorativeness.
