One end surface of the horizontal frame 130 is formed as a semicircular groove 132 so as to be in close contact with the outer surface of the first vertical frame 110. Here, when a plurality of horizontal frames 130 are coupled to the outer surface of the first vertical frame 110, one end of the adjacent horizontal frames 130 may be properly cut so as not to interfere with each other.

It allows to be inserted deeper into the transverse coupling hole 112 of the frame 110. As a result, one end of the horizontal frame 130 with respect to the outer surface of the first vertical frame 110 is induced to be more firmly coupled. As for the tanning bolt 180, a standard product sold in the market may be used as it is.

The stopper bolt 150 is formed with a hollow 151, which is formed with a male screw on the outer circumferential surface, and is inserted while being screwed to one end of the second vertical through hole 121 of the second vertical frame 120, but the second vertical through hole 121 ) A clearance space (121a) is placed at the most end and is inserted into the other side of the clearance space (121a).

Here, in order to rotate the wrench bolt 160 inserted deeply along the second vertical through hole 121 and screw it into the second binder 140, the second vertical frame 120 reaches the second end from the other side to the one end. A wrench having a sufficient length that can be inserted deep into the vertical through hole 121 may be used.

Here, in the case of FIGS. 4 to 6, an orthogonal coupling structure of a frame in which the first vertical frame 110, the second vertical frame 120, and the horizontal frame 130 are combined one by one is shown, and in FIGS. 3B and 3C As can be seen from the attached photo, in reality, the frame furniture occupies an orthogonal connection structure of the frame in which the first vertical frame 110, the second vertical frame 120, and the horizontal frame 130 are each one combined.

It is a series of reference diagrams for explaining a method for combining a frame and a horizontal frame.

In the method of manufacturing frame furniture according to an embodiment of the present invention, one end of the first vertical frame 110 and one end of the second vertical frame 120 face each other and are combined in a row, and the outer side of the first vertical frame 110 It is a method for manufacturing frame furniture that includes at least part of the orthogonal coupling structure of the frame in which one end of the horizontal frame 130 is orthogonally coupled to the side, and in particular, the method for configuring the orthogonal coupling structure of the frame will be described. I will do it.

For this purpose, the extrusion molding step of the basic member is first performed. In this step, a metal rod having a through hole formed in a longitudinal direction therein and a plurality of wedge-shaped satellite holes 114 formed radially to communicate with the through hole as a center is extruded as a basic member. The extruded base member is shown in the picture attached to FIG. 7 and is used by performing detailed processing on the base member as well as surface treatment such as anodizing, anodizing, painting, and plating.

Thereafter, the manufacturing step of the first vertical frame 110 proceeds. In this step, the extruded basic member of FIG. 7 is cut to a designed length to prepare a first vertical frame 110 having a first vertical through hole 111.

A corner portion coupled in a direction and a straight portion coupled in a form in which the plurality of horizontal frames 130 face 180 degrees with respect to the first vertical frame 110 are separately formed. Alternatively, it is a good method to form three longitudinal coupling holes 113 and lateral coupling holes 112 each so that the first vertical frame 110 can be used for both corner portions and straight portions. The shape of the first vertical frame 110 manufactured in this way can be seen in the middle of FIG. 8. (For reference, in Fig. 8, a first vertical frame in the middle, a second vertical frame and a horizontal frame are arranged on the right and left sides respectively)
