Chamfered and formed.

  Next, the manufacturing method of this door T is demonstrated. The manufacturing method of the door T comprises a core material processing step (1), a decorative plate processing step (2), and a decorative plate application step (3). Each step will be described below.

(1) Core Material Processing Step As shown in FIGS. 4 to 6, a recess core material 20A and a general core material 20B are prepared. A groove-like recess 12 is formed on one flat surface 21 of the core member 20 between the side surfaces of any other set (in the embodiment, a pair of side surfaces 24 and 24 opposed in the longitudinal direction). In the embodiment, as shown in FIG. 6, the recess 12 is formed in an elongated rectangular recess core member 20 </ b> A. In this case, since the recess 12 is formed in the recess core 20A, the recess 12 can be formed in a small member, and the handling is easy and the manufacturing can be easily performed. In this core material processing step, the covering material 25 is applied to the surface of the recess 12.

(2) Decorative Plate Processing Step As shown in FIG. 7, the decorative plate 30 has one side 35 and the other side 36 having side edges 34 that face each other on the recess 12 in the one plane 21 of the core member 20. The groove 37 is formed in the substrate 32 of the decorative plate 30 so that it can be bent at the corner portion of the core member 20. In this decorative plate processing step, the side edge 34 of the decorative plate 30 constituting the ridge 13 is also bent inward to form a double layer so that the substrate 32 corresponding to the portion to be bent is also formed. A groove 37 is formed.

(3) Decorative plate application process As shown in FIGS. 8 and 9, the side edge 34 of the one side 35 of the decorative plate 30 is from the opening edge 14 on one side of the recess 12 to the opening edge 14 side on the other side. The other protrusion 36 is configured as one protrusion 13 protruding toward the other side, and the side edge 34 of the other side part 36 protrudes from the opening edge 14 on the other side of the recess 12 toward the opening edge 14 side on the one side. The decorative plate 30 is bent at the groove 37 with respect to the core member 20 so as to be configured as the strip 13, and is attached with an adhesive or the like. In this decorative plate attaching step, the side edge 34 of the decorative plate 30 constituting the ridge 13 is bent inward to form two layers. Thereby, in the handle part 11, since the protrusion 13 can be formed only by attaching the decorative board 30 to the core material 20, manufacture of a handle can be made easy. Further, an edge tape 31 is attached to the pair of side surfaces 24, 24 of the other set facing each other and the end surface of the decorative plate 30 flush with the side surfaces 24, 24.

The door T formed in this way is attached to the storage S as shown in FIG. In the storage S, the door T is opened and closed as follows.
As shown in FIG. 10, for example, in the case of the left door T (L) with the handle portion 11 on the right side of the door T and the hinge portion on the left side, as shown in FIG.

On the other hand, as shown in FIG. 10B, when opening with the left hand, the opening operation can be performed by hooking a finger on the right ridge 13 with the palm facing the right side. Accordingly, the opening operation can be performed with a comfortable posture of the hand without twisting the hand.

  Further, as shown in FIG. 11, for example, in the case of the right door T (R) with the handle portion 11 on the left side of the door T and the hinge portion on the right side, as shown in FIG. When trying to do so, it is possible to perform an opening operation by placing the finger on the left ridge 13 with the palm facing left. On the other hand, as shown in FIG. 11B, when opening with the left hand, the opening operation can be performed by hooking a finger on the right ridge 13 with the palm facing the right side. Accordingly, the opening operation can be performed with a comfortable posture of the hand without twisting the hand. That is, both the left door T (L) and the right door T (R) can be opened with the right hand or the left hand in an easy hand posture, increasing the degree of freedom of fingering and opening operation. It is possible to improve the operability.

  This means that, as shown in FIG. 12, even when trying to open the left and right doors T (L) and T (R) simultaneously with both hands, the opening operation can be performed with an easy posture of the hands. To do. That is, in the prior art, the right hand and the left hand had to be twisted so that the backs of these hands face each other (FIG. 17). On the other hand, in the present invention, the palm sides are opened facing each other. Therefore, the operation becomes extremely easy and the operability is improved. Although the operation is difficult to perform, it goes without saying that the right hand and the left hand may be opened by twisting their hands so that the backs of these hands face each other, as in the conventional case.

  In the storage S, the door T is opened and closed repeatedly, but the handle portion 11 is formed in two layers by bending the side edge portion 34 of the decorative plate 30 constituting the ridge 13 inward. The strength can be increased and the durability can be improved.
