FIGS. 1 to 7 relate to the first invention, and FIGS. 8 to 11 relate to the second invention. First, a structure for reinforcing a bent portion of a decorative board as a skirting board according to the first invention will be described with reference to the drawings. P1 is a decorative board suitable as a skirting board, and the decorative ridge 1 is integrally formed over the entire upper part of the decorative board during use.
As the decorative board P1 in the present invention, a so-called two-type overlay plywood in which a decorative paper (printing paper) on which a wood grain and various patterns are printed is coated on the surface of a known hard board (hard fiber board) or ordinary plywood material. Time is used.

Usually, the baseboard is a member attached to a portion intersecting with the floor at the lower part of the wall, and is set to a height of about 6 to 12 cm to protect the lower part of the wall, and is resistant to contamination and damage. In addition, although a decorative effect is also expected, the decorative raised portion 1 has a shape that particularly contributes to the improvement of the decorative effect in the baseboard. Reference numeral 2 denotes a decorative paper having excellent elasticity and appropriate strength. Particularly, FIGS. 3 and 4 show the decorative paper with imaginary lines. Reference numeral 3A denotes a bent portion of the decorative board P1 having a shape suitable for being attached to a lower part of a corner of a wall as a baseboard accessory (FIG. 3).

In order to function as a member of the corner portion, on the opposite surface of the bent portion 3A from the surface to which the decorative paper 2 is adhered, the decorative raised portion 1 is roughly V-shaped and the bottom is inverted M-shaped. A groove 4 is formed. At the bottom of the groove portion 4, a guide portion 6 for appropriately exerting the function as a member of the corner portion is interposed at a lower edge portion of the inclined surface 5 facing the guide portion 6.

As shown in FIG. 3, the guide portion 6 has a triangular prism shape with an upper portion having an acute ridge line. An outer portion (corresponding to the bent portion 3A) of the groove portion 4 is formed with an obtuse angled chamfer 7 at two places via the decorative paper 2. The chamfer 7 means that, as is generally used, the same appearance as in the case of performing decorative surface processing (processing of shaving off a corner) on the side surface is obtained. According to the configuration of the present invention, a corner portion member can be obtained by the groove portion 4 and the guide portion 6 inside the bent portion 3A.
On the outside of A, the face 7 is formed, and the decorative board P
A form is obtained in which the adjacent decorative ridges 1 are bent in close contact with no acute gap without gaps over the entire upper portion.
