As shown in FIGS. 1 and 2, each of the facing materials 30 is bent in an L-shape inward in the thickness direction of the door 10 along left and right corners located at both ends in the width direction of the door 10. A pair of left and right bent portions 31, 31 and a pair of left and right butted ends 32, 3 located at the distal end of each bent portion 31 and abutting substantially at the center in the thickness direction of the door 10.
2 are formed respectively.

As shown in FIG. 3, a notch 33 having a V-shaped cross section is formed along the height direction of the door 10 on the inner surface of each bent portion 31 of the front material 30. More specifically, as shown in FIG. 3, the notch 33 is formed by a plurality of, in this case, four notches 33a to 33d which form an acute angle and extend radially at predetermined angular intervals. Three wedge-shaped connecting pieces 34a to 34c radially connected are left in the space between the parts 33a to 33d.

Although not shown, an adhesive is poured into the four notches 33a to 33d to join the adjacent connecting portions 34a and 34b, 34b and 34c to each other, and to connect the outermost connecting portions 34a and 34c.
Notch portions 33a, 33d located on the outermost sides of c
By joining to the slopes 35a and 35b formed by
Is bent substantially 90 degrees as shown in FIG. And when the bent portion 31 is bent,
As shown in FIG. 4, an arc surface 36 bent in an arc shape is formed on the outer surface thereof.

In addition, as shown in FIG. 3, a notch having a V-shaped cross section is formed at a substantially right angle on the inner surface in front of each abutting end 32 of the surface material 30.
37 are formed along the height direction of the door 10, respectively. More specifically, as shown in FIG.
A bent portion 38 having a right-angled triangular shape is formed at the tip of the.

Then, although not shown, an adhesive is poured into the notch portion 37, and the folded portion 38 is folded back so as to be folded inward from the notch portion 37, and as shown in FIG. The end face 39 is used as the surface material. Here, the decorative sheet 40 is placed on the surface of the surface material 30.
The decorative sheet is attached to the front end face 39
40 surfaces are exposed.

In FIG. 2, reference numeral 50 denotes a sound insulating material.
Are fixed in a state of being sandwiched between the facing end surfaces 39 of the both facing materials 30 that abut each other. As shown in FIG. 2, the sound insulating material 50 protrudes outward from the outer edge in the width direction of the door 10, and although not shown, elastically slides on the door frame to achieve a sound insulating effect.

Next, a method of manufacturing the door 10 using the core members 20 to 22 and the surface member 30 having the above-described configuration will be described.

First, although not shown, core material is cut out from the square bar,
Prepare three core materials 20 to 22 with different t1 and t2, and
Is well dried.

Similarly, although not shown, the plywood is cut to a required size to prepare two sheets of the surface materials 30, 30.
3 and the cut portion 37 are processed in advance, and then sufficiently dried. After drying, the decorative sheet 40 is bonded to the surface of each surface material 30.

Next, although not shown, three cores 20 to
22 are placed in parallel with each other at predetermined intervals in a substantially river shape, and an adhesive (not shown) is attached to one of the sides facing upward.
Respectively.

On the other hand, on each inner surface of the notch 33 and the notch 37 of both surface materials 30,
An adhesive (not shown) is applied to each. After that, one surface material 30 was placed on the 34 core materials 20 to 22 placed on the shallow beam,
It is pressed with its back face down. Thereby, the respective application surfaces of the adhesive (not shown) of the core members 20 to 22 are joined to the back surface of the front member 30.

When the surface material 30 is placed on the three core materials 20 to 22 placed on the shallow rail, the central core material 20 is vertically joined to the center of the width of the surface material 30, and The left and right core members 21 and 22 are joined together along the inner edge of the notch 33 of the front member 30.

Next, the surface material 30 to which the core members 20 to 22 are joined is inverted on the shallow beam, and is placed on the shallow beam with the face having the decorative sheet 40 joined to the surface of the surface material 30 facing down.

After the surface material 30 is turned over, an adhesive (not shown) is applied to each of the other side surfaces of the core materials 20 to 22 facing upward.

Thereafter, the adhesive of the core members 20 to 22 is arranged such that the other surface member 30 is vertically symmetrical with the front member 30 to which the core members 20 to 22 have been joined, with the back surface thereof facing down. To each application surface.

If the two tops 30 are joined up and down with the cores 20 to 22 interposed therebetween, remove them from the shallow rail and use a press machine (not shown) to move the two tops 30 toward the cores 20 to 22 Crimp.

When two sheets of material 30 are pressed against each other, the thickness of three core materials 20 to 22 is increased.
Since t1 and t2 are different, and the thickness t1 of the central core 20 is larger than the thickness t2 of the left and right cores 21 and 22, as shown in FIG. When the center applied to the cores 20 to 22 is curved in a raised state and the adhesive applied to the cores 20 to 22 is hardened in this state, the both surface materials 30 are fixed to the cores 20 to 22 in a curved state.

Then, an adhesive (not shown) is applied to the outer surfaces of the left and right core members 21 and 22 facing each other.

Then, from each of the cut portions 37 to which the adhesive has been applied to both ends of the front material 30, each of the folded portions 38 is folded back inward as shown in FIG. The surface is the edge of the surface material
39. Thereafter, an adhesive (not shown) is applied to each of the front end surfaces 39 of both the front materials 30.

Next, as shown in FIGS. 1, 2, and 4, the respective bent portions 31 are formed in the thickness direction of the door 10 from the notched portions 33 of the front members 30 to which the same adhesive (not shown) is applied. Each is bent inward.

When the bent portions 31 of both the surface materials 30 are bent, the surface material end surfaces 39 facing each other come into contact with each other while approaching each other.
Here, the sound insulating material 50 is sandwiched between the two end faces 39 of the front material.

As shown in FIG. 2, the sound insulating material 50 is bonded to both the front end faces 39 by the adhesive applied to both the front end faces 39, respectively.

In addition, the inner surface of each abutting end portion 32 at the tip of the bent portion 31 of each of the front members 30 is joined to each of the adhesive application surfaces of the left and right core members 21 and 22, thereby completing the manufacture of the door 10.

Incidentally, for the door 10 manufactured by the above-described manufacturing method, although not shown, a decorative tape may be attached to an upper edge or a lower edge of the door 10, or a decorative material may be fixed, or Then, a door knob or a locking device is appropriately attached, and the door is fixed to the door frame via a hinge so that the door can be opened and closed.

In the embodiment shown in the drawings, three cores 20 to
Although 22 are arranged at predetermined intervals in parallel with each other, a core material may be framed.

[Effects of the Invention] Since the present invention is configured as described above,
The following effects are obtained.

According to the door according to the first aspect, it is possible to omit the foreclosure that was conventionally required, so that the number of parts can be reduced, the manufacturing is easy, and the corners on both right and left ends of the door are neatly arcuate. A door can be provided that can be finished as a surface.

According to the door described in the second aspect, not only the end face treatment of each end face of the surface material can be omitted, but also the joining surface can be finished finely.

According to the door described in claim 3, it is possible to effectively prevent warpage of the surface material.

According to the method of manufacturing a door according to the fourth aspect, the joining process of the concealed edge which was conventionally required can be omitted, and each corner of the left and right side edges of the door is neatly finished as an arc-shaped surface bent in an arc shape. be able to.
