DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door corner piece which is fixed to a door part, particularly a door corner formed of a steel plate.

[0002]

2. Description of the Related Art With the progress of thinning technology of steel plates, a technology of manufacturing a wooden door with steel plates has been developed. For example, a decorative door in which a metal plate is used as a skin material and the interior of which is filled with an adhesive resin material can be easily formed by punching and bending a metal flat plate because the skin material is made of a metal material. There is an advantage that it can be formed into any external shape. Further, since an internal space formed between a pair of metal plates is filled with a resin material such as a foamed resin, the weight can be reduced, and it has been widely used in recent years.

[0003] In the manufacture of a decorative door, both sides of one metal plate, which has been decorated with a wood-grain pattern by sticking a wood grain pattern film, are curved or bent into a substantially U-shaped cross section or a U-shaped cross section. The other flat metal plate decorated similarly to the one metal plate is arranged between a pair of both sides of the metal plate, and the one and the other metal plate are joined by screwing or welding. next,
The bonded metal plate is set in a molding die, and an adhesive resin material such as urethane foam is filled between the metal plates.
For example, Japanese Unexamined Patent Application Publication No. 8-13941 discloses that a joint between two ends of a metal plate of a decorative door is inserted into a concave groove and a concave groove.
There has been disclosed a decorative door which is formed of a character-shaped folded piece and a cut surface of a metal plate is not exposed on the surface.

[0004]

By the way, in the conventional decorative door, after filling urethane foam between a pair of metal plates,
Both edges of the metal plate must be shielded by edge members to prevent urethane foam from falling off. In this case, if the lengths of the doors are different, the lengths of the doors after the installation will vary, and there is a disadvantage that the edge members corresponding to the lengths of the doors must be individually manufactured to a special size.

It is an object of the present invention to provide door corner pieces of the same shape that can be easily attached to doors of different lengths.

[0006]

Means for Solving the Problems A steel plate front panel (11) and a steel plate back panel (12) are fixedly separated by a gap (13) and fixed to a corner of a door. The door corner piece (10) of the present invention, which is integrally formed of a synthetic resin, has a substantially rectangular main wall (1).
A skirt portion (2) connected to the main wall (1) and projecting at right angles from the main wall (1) and having a recess (2e) formed therein; and a skirt portion (2) substantially parallel to the main wall (1). One end wall (2
a) tongue pieces (3) projecting from a). Tongue piece (3)

The folded back portion (12a) of the back panel (12) formed when joining the ends of the front panel (11) and the back panel (12) can be stored in the recess (2e) of the skirt portion (2).

After cutting the closing member (15) to a predetermined length, the tongue piece (3) of the corner piece (10) for the door is attached to the closing member (15), and the front panel (11) and the back panel (11) are mounted. (12) can be adjusted and mounted to fit the top or bottom. Therefore, leakage of the filler formed between the front panel (11) and the back panel (12) can be prevented. By adjusting the length of the closing member (15) that connects the door corner piece (10) using the door corner piece (10) as it is, even if the door length is changed, the door corner piece (10) can be used as it is. Accordingly, door corner pieces (10) of the same shape can be easily attached to doors of different lengths, and parts can be shared.

In the embodiment of the present invention, the other end wall (2d) of the skirt (2) is provided with the concave portion (2e) and the inclined surface (2).
f) is formed. Circular hole (6) formed in main wall (1)
Is a cylindrical tube (7) projecting parallel to the skirt (2)

FIGS. 12 to 16 show the door corner piece 10 on the left end side. The circular hole 6 and the cylindrical portion 7 are removed from the door corner piece 10 on the right end side shown in FIGS. Since it has a shape, the description is omitted.

After cutting the closing member 15 to a predetermined length,
The tongue piece 3 of the door corner piece 10 can be attached to the closing member 15 so as to be adjusted to a length suitable for the top or bottom between the front panel 11 and the back panel 12. Therefore, leakage of the urethane resin (fill) formed between the front panel 11 and the back panel 12 can be prevented. If only the length of the closing member 15 for connecting the door corner piece 10 is adjusted by using the door corner piece 10 as it is, the door corner piece 10 can be used as it is even if the door length is changed. Can be. Therefore,
Corner pieces 10 for doors of the same shape even for doors of different lengths
Can be easily attached, and parts can be shared.

In the above embodiment of the present invention, the present invention is applied to a folding door, but the present invention can be applied to a hinged door or a sliding door. In addition, the tongue piece 3 of the corner piece 10 for a door can be formed in various shapes to be fitted to the closing member 15. For example, as shown in FIG. 17, it may be formed to a certain thickness, or two or more tongue pieces may protrude from the skirt portion 2. Further, as shown in FIG. 18, a notch 3b may be formed in the tongue piece 3.

[0019]
