DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of a frame member and a fitting used therefor, and more particularly, to a window frame material, a window frame material or a window frame cover material for forming a building opening. It relates to a coupling structure that is often used in some cases.

Particularly, it is optimally used when assembling a frame-type window frame cover having a curtain plate portion for closing and covering a gap between a window frame provided on the outer wall surface side of the building and the inner wall surface. The present invention relates to a coupling structure of a frame member.

[0003]

2. Description of the Related Art In general, when assembling the window frame cover, conventionally, ends of frame members constituting the window frame cover are brought into contact with each other, and are previously assembled in a frame shape by nailing or screwing. And then adjusting it to the size of the window opening.

However, this conventional working method has the following problems. Since the frame member that constitutes the window frame cover is long, it is inherently difficult to handle and swing.However, the edges of these frame members are aligned and abutted, and the nail is held down so as not to shift. The work of assembling by hammering or screwing is extremely time-consuming, and is one of the major obstacles to shortening the construction period.

[0005] Further, when it is necessary to adjust what has been temporarily assembled by nailing or screwing, it is convenient.
It is necessary to pull out the nail with a tool and re-strike, or re-screw with a screwdriver. However, the work of pulling out nails and re-hitting or re-fastening screws is not only time-consuming, but also troublesome and unfavorable for the mental health of workers. It is also a factor that leads to a decrease in work efficiency from an economical aspect.

In order to perform the work of assembling by nailing or screwing while holding the ends of the frame members in contact with each other and holding them so as not to be displaced,
If considerable skill is required and the person is not a skilled person, the work may be performed by two persons, resulting in a rise in labor costs.

[0007]

In view of the above situation, the present inventor can perform assembling with high working efficiency, and can easily perform adjustment in the stage of adjusting the assembled one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 shows an embodiment in which the present invention is applied to the assembly of a window frame (100), and a window frame material (1).
FIG. 10 is a partial lower perspective view when one corner portion is viewed from the outside when the window frame (100) is combined with a square.

When the window frame material (1) is joined in a rectangular shape, the edge of the window frame material (1) is generally cut at an angle of approximately 45 degrees with respect to the length direction, and these edges are brought into contact with each other. Then they are combined into a square. When the frame members are joined in a rectangular shape, the end of one frame member is brought into contact with a side portion near the end of the other frame member without cutting at an angle of 45 degrees as described above. In some cases, the two frame members may be arranged at right angles and joined together. In the present specification, the term “ends” of the frame members is referred to as including in such a case, and the present invention can be applied to such a case.

Conventionally, nailing or screwing is performed on the contact portion to perform connection, and it is not easy to perform nailing or screwing work while holding the contact portion so as not to shift. .

In the present invention, the window frame (100) is assembled by using a new specific fitting (2) and using the fitting (2) in a specific manner. FIG. 2 shows a perspective view of a typical embodiment of the fitting (2) used in the present invention. This coupling metal fitting (2) is characterized in that return claws with their toes directed toward the center of the metal fitting are provided near both ends in the length direction of the metal fitting.
