Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of packing a door unit consisting of a bifold door body and a door frame.

Normally, this type of door unit is packaged in an exterior box with the bifold door folded or with the hinges removed and two door panels stacked on top of each other. Since the cardboard box containing the upper and lower frames and both side frames must be stored in the outer box together with the door body, the cardboard box does not fit well, and as shown in Figure 4, a cushioning material 10 is used to protect the door panel surface. and a cushioning material 10 for holding the cardboard box 8, resulting in the problem that not only a large amount of cushioning material is required, but also the outer box becomes large.

The present invention has been made in view of the above problems, and provides a cardboard box in which door frame assembly members are housed by utilizing the wedge-shaped slope formed when the bifold door body is folded into a V-shape. The purpose of this invention is to reduce the amount of cushioning material required.

The present invention will be explained in detail below with reference to embodiment figures. 1st
The figure shows the door unit assembled, and Figure 2 shows the door unit disassembled and packed.
A cardboard box 8 houses a bifold door body 3 formed by foldably connecting two door panels 2 with a hinge 1, and door frame assembly members 7 such as upper and lower frames 5 and side frames 6 that constitute the door frame 4. In the packaging method, the cardboard box 8 is sandwiched between both door panels 2 of the bifold door body 3, and the hinge of the bifold door body 3 folded into a V-shape is stored. A cushioning material 10 is interposed in a space formed between the first end and the inner surface of the outer box 9.

FIG. 3 shows an example of a double-opening bifold door, in which two sets of bifold door bodies 3 each hold a cardboard box 8, and door frame assembly members 7 are separately stored in both cardboard boxes 8. be. A protective sheet material 11 such as cardboard may be interposed between the door bodies 3. If necessary, a protective sheet material 12 bent into an L-shaped cross section is interposed between the side edge of the door panel 2 and the inner corner of the outer box 9.

The present invention is constructed as described above, and since the cardboard box containing the door frame assembly members is held between the door body which is folded into a V shape as a cushioning material, the cardboard box is used as a cushioning material. There is no need for a cushioning material or holder to hold the box, and since the door panel surface is held diagonally to the inner surface of the outer box, the cushioning material only needs to be placed on the hinge side end of the door body. At that time, the cushioning material is held in the wedge-shaped space formed by the inner surface of the outer box and the door panel surface, so there is no need for it to be pushed against the edge of the outer box and cause positional displacement. This has the advantage that there is no need to attach cushioning material to the inner surface of the outer box.

Claims (1)

[Claims] 1 A bifold door body made up of two door panels foldably connected by a hinge, and a cardboard box containing parts for assembling the door frame such as the upper and lower frames and both side frames that make up the door frame are combined into a rectangular parallelepiped-shaped exterior box. In the packaging method of storing the cardboard box inside, the cardboard box is sandwiched between both door panels of the bifold door body, and between the hinge side end of the bifold door body folded into a V shape and the inner surface of the outer box. A method for packaging a bifold door unit, characterized by interposing a cushioning material in the formed space.
