DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A furniture door and a method of manufacturing the same according to an embodiment of the present invention will be described below with reference to FIGS.

The furniture door 1 according to the embodiment of the present invention
For example, it is installed in a storage in a kitchen, and includes a rectangular substrate 2 and a frame 3 arranged on the front surface side of the substrate 2.

As the substrate 2, a particle board in which a chip material is solidified is used, and a decorative material (for example, a sheet-shaped synthetic resin with a design) 4 is heated and pressed on the front, back and side surfaces thereof.

A frame-shaped (square-shaped) mounting groove 5 is formed on the peripheral edge of the surface of the substrate 2, and arc-shaped enlarged portions 6 are formed at four corners of the mounting groove 5. Further, the frame 3 is formed in a frame shape by joining a plurality of (four in the figure) thin frame members 7, and the same decorative material 4 as the substrate 2 is heated and pressed onto the surface of the frame 3. Mounting groove 5 on the back
A stepped portion 8 which is fitted and joined to the frame member 7 is formed, and the stepped portion 8 is formed of a thickened portion 8 a having a width smaller than that of the frame member 7 formed on the back surface of each frame member 7.

A handle 10 is attached to the surface of the substrate 2, and the forehead member 7 on the opposite side to which the handle 10 is attached has
A hinge 9 for attaching the furniture door 1 to the furniture body 15 is attached.

Next, a method of manufacturing the furniture door 1 having the above-described structure will be described. This is automated by a manufacturing machine. First, the substrate 2 is formed into a rectangular shape by using a chip material. The decorative material 4 is heated and pressed on the front surface, the back surface, and the side surface, and the mounting groove 5 is formed on the peripheral edge of the surface of the substrate 2.

When the mounting groove 5 is formed, for example, a round blade is rotated, and when the round blade reaches the corner of the substrate 2, the substrate 2 and the round blade are relatively slightly moved in the radial direction. To form the enlarged diameter portion 6.

On the other hand, the end of each forehead member 7 is cut so as to be inclined at an angle of 45 ° in the opposite direction to the longitudinal direction of the forehead member 7, and an adhesive is applied to the cut end surface to apply a high frequency (for example,
The frame 3 is formed by heating and bonding at 7.12 MHz). Each of the forehead members 7 has a thickened portion 8 serving as a stepped portion 8.
a in which a is formed in advance is used.

Then, an adhesive is applied to the mounting groove 5, and the stepped portion 8 formed on the back surface of the frame 3 is fitted into the mounting groove 5,
Pressing and joining. At this time, since the circular blade is slightly moved in the radial direction to form the arc-shaped enlarged portion 6 at the four corners of the mounting groove 5, the corner of the stepped portion 8 becomes the enlarged portion 6. The board 2 and the picture frame 3 can be securely fixed.

As described above, according to the embodiment of the present invention,
A rectangular substrate 2 is formed, and mounting grooves 5 are formed on the surface of the substrate 2.
