In consideration of the assembly margin, it is made slightly larger than the width of the convex portion 6b.

In addition, a plurality of screw holes penetrating side surfaces of the third and fourth frames 10 and 12 at upper and lower ends of the third and fourth frames 10 and 12 facing the first and second frames 6 and 8. 18 is formed, and a plurality of first screw grooves are formed on one side of the first and second frames 6 and 8 opposite to the third and fourth frames 10 and 12 in an extension line of the screw hole 18. 20) is formed.

That is, FIG. 5 is an enlarged view of a part of FIG. 2 for explaining a combined portion of the second frame and the third frame, and FIG. 6 is a right side view of the third frame shown in FIG. 5, and the third frame 10 is A third frame having a pair of screw holes 18 formed at a lower end portion opposite to the second frame 8 so that the screw holes 18 have an outer surface of the third frame 10 and a second recessed portion 10a is formed. Penetrates the internal cut surface of (10).

Thus, the fastening bolt 14 is fitted into the screw hole 18 during the assembly of the door assembly 2 to penetrate the third frame 10 from the side.

FIG. 7 is a left side view of the second frame illustrated in FIG. 5, and the one side cutting surface of the second frame 8 opposite to the third frame 10 includes a respective screw hole provided in the third frame 10. Corresponding to 18), a first screw groove 20 having a predetermined depth connected to the screw hole 18 is formed.

In addition, a second screw groove 22 having a predetermined depth is formed at the end of the first screw groove 20 from the rear surface of the second frame 8 toward the front surface to be connected to the first screw groove 20. The second screw groove 22 is for assembling the fixing bolt 16, and the fixing bolt 16 is fitted into the second screw groove 22 to assemble the end of the fastening bolt 14 during the assembly of the door assembly 2. It will be fixed.

As described above, detailed configurations of the second frame 8 and the third frame 10 are described with reference to FIGS. 5 to 7, but the first frame 6 and the second frame 8 are shaped to be compatible with each other. And the dimensions are made the same, the third frame 10 and the fourth frame 12 is also made the same shape and dimensions to be compatible with each other.

On the other hand, the door plate and the first frame (6) to the fourth frame (12) can all be used in a variety of different materials and colors, etc. according to the user's preference, in this case, the design of various designs to suit the user's preference It becomes possible. And both the door plate 4 and the first frame 6 to the fourth frame 12 are provided to the user with both the edge and the cut surface closed.

Next, an assembling process of the door assembly will be described based on the door assembly configuration described above.

First, as shown in FIGS. 1 and 2, the fastening bolts 14 are fitted into the respective screw holes 18 provided in the third and fourth frames 10 and 12, and the fastening bolts 16 are fastened to each other. The first and second frames 6 and 8 are fitted into the second screw grooves 22 provided on the rear side thereof.

The first and second frames 6 and 8 are fitted to the upper and lower ends of the door plate 4 to be fixed. In this process, the upper and lower ends of the door plate 4 are accommodated in the first recesses 6a and 8a provided in the first and second frames 6 and 8, so that the door plate 4 and the first and second ends are accommodated. Frames 6 and 8 are integrally assembled.

Next, the third and fourth frames 10 and 12 are fitted into and fixed to the left and right ends of the door plate 4 and the first and second frames 6 and 8. In this process, the left and right ends of the door plate 4 and the convex portions 6b and 8b provided in the first and second frames 6 and 8 are the second recesses 10a of the third and fourth frames 10 and 12. 12a), the door plate 4 and the first frame 6 to the fourth frame 12 are integrally assembled.

As shown in FIG. 8, the fastening bolts 14 are inserted into the first screw grooves 20 through the screw holes 18 by tightening the fastening bolts 14 using a conventional drill or a driver. This allows the fastening bolts 14 to form the third frame 10 and the first and second frames 6 and 8, and the fourth frame 12 and the first and second sides of the third and fourth frames 10 and 12. The frames 6 and 8 are tightened to fix them.

At this time, the end of the fastening bolt 14 is located between the threads of the fixing bolt 16 coupled to the second screw groove 22 of the first and second frames 6 and 8, and a conventional drill or driver By tightening the fixing bolt 16 using the fixing bolt 16 is fixed to the end of the fastening bolt (14).

Accordingly, the fixing bolt 16 pulls the fastening bolt 14 in the direction of the arrow in FIG. 8 to prevent the fastening bolt 14 from being separated, and at the same time, the first and second frames 6 and 8 and the third and fourth frames. (10, 12) serves to increase the binding force.

As described above, the door assembly according to the present embodiment can easily complete doors of various designs according to the user's preferences as the user directly manufactures the door by DIY (Do It Yourself) method, and partial replacement and repair of the door It has an easy advantage.
