[0010]

The present invention will be described below in detail with reference to examples. FIG.
1 shows an embodiment of the present invention. First, an example of a method for manufacturing the frame A will be described. A long base material 4 having a substantially square cross section (a vertically long rectangle) made of a laminated material or a laminated material is used, and the upper, lower, left, and right surfaces of the base material 4 have a thickness of 2 as shown in FIG. An MDF board (medium density fiber board) 5 of 6 mm is attached. Next, a chamfering process for forming the chamfered surface 2 is performed by diagonally notching the end of the MDF plate 5 at a pair of ridges facing the diagonal line of the base material 4. Next, the MDF plate 5
A thin wooden veneer 3 having a thickness of about 0.2 to 0.3 mm is stuck on the surface of. The veneer veneer 3 is a single veneer, which is wound around the outer periphery of the base material 4 and is attached. The start and end of the veneer veneer 3 are on the ridge portion where the chamfered surface 2 is not provided. It is good to be located near. Thus, the frame body 9 can be created.

As shown by a dashed line in FIG. 1 (a), the base material 4 is formed by an oblique line connecting the vicinity of a pair of ridge portions where the chamfered surfaces 2 of the left and right surfaces of the base material 4 are not provided. The frame element 9 is divided into two equal parts by cutting along the longitudinal direction.

[0017]

As described above, according to the present invention, the frame body is formed in a substantially right-angled triangular cross section having a horizontal upper surface, a vertical front surface, and an inclined rear surface, and the ridge line between the upper surface and the front surface is cut off. Since the decorative veneer is attached from the upper surface of the frame body to the chamfer surface and the front surface, the volume is small except for the horizontal upper surface and the vertical front surface exposed in the construction state. By forming the frame main body, the portion of the frame that is not exposed to the surface can be made smaller and material loss can be reduced, and a decorative veneer can be pasted on a chamfered surface. This eliminates the need to use a thick veneer as a decorative veneer.

Further, the frame body is formed of a base material having a substantially right-angled triangular cross section and an MDF plate attached to the surface of the base material. It can improve scratch resistance and crack resistance. Furthermore, on the inclined back surface of the frame body, a fitting recess into which the end portion of the fixing member such as a large-scale is fitted is recessed,
Alternatively, since a bundle receiving material having a substantially right triangle shape is attached by joining its oblique pieces, the frame body is formed using a fitting recess or a bundle receiving material despite the fact that the frame body is formed in a substantially right triangle shape in cross section. It is possible to easily perform the work of stably mounting the main body.
