DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for packing a door unit in a packing case.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, a door unit A has a door frame 1 in which a pair of left and right vertical frames 1a and a pair of upper and lower horizontal frames 1b are framed in a rectangular shape. Door panel 2 which is connected to the door bottom side so as to be rotatable with hinges 8
The packing case 3 is made of corrugated cardboard or the like, and has a rectangular box-shaped upper case 3a having an open lower surface and a rectangular box-shaped lower case 3b having an open upper surface. Have been. Then, pack the door unit A into the packing case 3.
In order to prevent the door panel 2 from moving in the packing case 3, a plurality of door panels 2 are provided between the door end side of the door panel 2 and the bottom surface of the lower case 3b (in the case of the present embodiment). 3) panel receiving pad 4 and door panel 2
A buffer material 5 such as a feather core is interposed between the upper case 3a and the upper bottom surface of the upper case 3a.

As another conventional example, Japanese Utility Model Application Laid-Open No. 63-86 is disclosed.
No. 082 is disclosed. This is also basically the same as the conventional example as shown in FIG. 5, but differs only in the structure for supporting the door end side of the door panel 2. That is, the door stop 6 is attached to the inner periphery of the door frame 1 with an adhesive or the like, and the protection member 7 is fitted on the end of the door panel 2 on the door end side, and this end is placed on the door stop 6. I support it.

[0004]

However, in the former case of the above-mentioned conventional example, the panel receiving pad 4 moves up and down when the lower case 3b is slackened by a load, and the door panel 2
And the door panel 2 may be damaged, and the panel receiving pad 4 must be fixed to the lower case 3b, which takes a long time to pack.

In the latter case of the prior art, the end of the door panel 2 on the door end side is supported by a door stop 6, but the door stop 6 is necessary only because it is fixed by bonding or the like. When the above load is applied, there is a problem that the door stop 6 comes off, and there is a problem that extra parts such as the protective material 7 are required. The present invention has been made in view of the above problems, and an object of the present invention is to provide a door unit packing structure that can stably support a door panel, does not damage the door panel, and can be easily packed. To provide.

[0006]

To achieve the above object, the packing structure of the door unit according to the present invention comprises a pair of left and right vertical frames 1.
a and a pair of upper and lower horizontal frames in a rectangular frame 1
A door unit A comprising a door panel 2 which is disposed in the door frame 1 and has a door bottom side rotatably connected to the door bottom side with a hinge 8.
In a packing structure of a door unit for storing in a packing case 3 made of corrugated cardboard or the like, a receiving member 9 made of synthetic resin is connected between an end of the door panel 2 on the door end side and a vertical frame 1 a of the door frame 1. A receiving portion 9a having a substantially L-shaped cross section of the receiving member 9 is fitted to the door end side of the door panel 2 and a hook 9b having a substantially U-shaped cross section of the receiving member 9 is hooked on the vertical frame 1a. It is characterized by being locked.

Further, a receiving member 9 integrally provided with a receiving portion 9a having a substantially L-shaped cross section and a hook portion 9b having a substantially U-shaped cross section is formed in an elongated shape, and is received at a position corresponding to the knob 10 of the door panel 2. The cutout 11 is provided in the portion 9a.

[0008]

According to the above construction, when the door unit A is housed in the packing case 3 and packed, the receiving member 9 is arranged between the end of the door panel 2 on the door end side and the vertical frame 1a. 9 is fitted to the end of the door panel 2 and the hook 9b of the receiving member 9 is fitted to the vertical frame 1a.
The end of the door panel 2 on the door end side can be supported by the vertical frame 1 a via the receiving member 9. Thereby, the support of the door panel 2 is stabilized, and there is no possibility that the door panel 2 is damaged, and the packing can be easily performed without taking much time.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A door unit A is formed by attaching a door panel 2 to a door frame 1 so as to be openable and closable. The door frame 1 is formed by forming a pair of left and right vertical frames 1a and a pair of upper and lower horizontal frames into a rectangular shape. The outer periphery of the door frame 1 is used to attach a door stop over the entire circumference. A mounting groove 12 is provided. A rectangular door panel 2 is arranged in the door frame 1, and the door end of the door panel 2 is hinged to one vertical frame 1 a of the door frame 1 with a hinge 8 so that the door panel 2 can be freely opened and closed. Have been. A knob 10 is provided on the door end side of the door panel 2 as needed. The packing case 3 is formed of corrugated cardboard, and has a rectangular box-shaped upper case 3a having an open lower surface and a rectangular box-shaped lower case 3b having an open upper surface.
It is composed of The receiving member 9 is provided integrally with a receiving portion 9a having a substantially L-shaped cross section and a hook portion 9b having a U-shaped cross section, and is formed of a synthetic resin such as a hard vinyl chloride resin. The receiving member 9 may be a short object or a long object. When the receiving member 9 is a long object, the notch 1 for releasing the knob 10 of the door panel 2 as shown in FIG.
1 is provided.

Before the door unit A is stored in the packing case 3, the receiving portion 9a of the receiving member 9 is fitted to the end of the door panel 2 on the door end side, and the hook portion 9b is fitted to the vertical frame 1a. The door panel 2 is supported on the vertical frame 1a via the receiving member 9. In this state, the door unit A is inserted between the upper case 3a and the lower case 3b of the packing case 3, and the cushioning material 5 such as a feather core is interposed between the door panel 2 and the upper bottom surface of the upper case 3a. . When packed as shown in FIG. 1 in this manner, the door end side of the door panel 2 is securely supported via the receiving member 9, and the door panel 2 can be prevented from being damaged. The receiving member 9 to be interposed between the door end side of the door panel 2 and the vertical frame 1a may be a short object or a long object. In this case, the knob 10 is released from the knob 10 by positioning the knob 10 in the notch 11.

[0011]

According to the present invention, as described above, a receiving member formed of a synthetic resin is interposed between the end of the door panel on the door end side and the vertical frame of the door frame, and the receiving member has a substantially L-shaped cross section. The receiving portion is fitted into the door end side of the door panel and the receiving member has a substantially U-shaped cross section.
Since the hook-shaped part is hooked and locked on the vertical frame,
The vertical frame can support the end portion of the door panel on the door end side via the receiving member. The support of the door panel is stable, there is no possibility of the door panel being damaged, and the packaging can be easily performed without time. Things.

In the invention according to claim 2 of the present invention, a receiving member integrally formed with a receiving portion having a substantially L-shaped cross section and a hook portion having a substantially U-shaped cross section is formed in a long object, Since the notch is provided in the receiving part at the position corresponding to the knob on the door panel, even if a long object is used as the receiving member, the receiving member can be attached avoiding the knob by positioning the knob in the notch. You can do it.
