It becomes possible.

The best mode for carrying out a cabinet provided with a storage body formed of a resin molded product according to the present invention will be described below with reference to the drawings based on the embodiments.

An embodiment of a cabinet provided with a storage body formed of a resin molded product according to the present invention will be described with reference to FIGS. In this embodiment, the storage portion of the cabinet 2 is provided below the top plate 3 of the cabinet 2, and the auxiliary storage portion 1 is attached to the front side thereof.

  The storage unit functions as a main storage unit with respect to the auxiliary storage unit 1. In this embodiment, a drawer storage portion 4 is provided as a storage portion. As shown in FIG. 1 (b), the drawer storage portion 4 includes a front surface portion 5, left and right side plates 6, a bottom plate 7, and a back plate (not shown).

  The auxiliary storage unit 1 is provided below the top plate 3 so as to be positioned in front of the drawer storage unit 4. The auxiliary storage portion 1 is attached to the upper portion of the front surface portion 5 of the drawer storage portion 4 so that at least a part thereof is positioned in front of the front end of the top plate 3.

  The auxiliary storage unit 1 communicates with the drawer storage unit 4 to form an integral storage space. In this embodiment, as shown in FIGS. 1 (a) and 1 (b), the auxiliary storage portion 1 includes a storage body 8, and side surfaces 10 (see FIG. 1 and FIG. 2), the side cap 9 is attached. In this embodiment, the resin molded product according to the present invention is the storage body 8 of the auxiliary storage portion 1.

  The storage main body 8 is a long member having the same lateral width as the drawer storage portion 4 and is formed by extrusion molding. Each side surface 10 at both ends in the longitudinal direction is open. . FIG. 2A shows a perspective view of a portion of the storage body 8 cut out from one end in the longitudinal direction, and FIG. 3A shows a side view thereof.

  As shown in FIGS. 2 (a) and 3 (a), the storage body 8 includes a front wall 11, an inclined wall 12 coupled to the lower portion of the front wall 11, and a bottom wall coupled to the inclined wall 12. 13 and a back wall 14. When the user faces the auxiliary storage portion 1 from the front side, the surface portion 23 serving as a decorative surface on the front side of the front wall 11 becomes visible.

  A thick wall portion 11 'having a substantially circular cross section is formed at the upper end of the front wall 11, and a screw hole 15 is formed on a side surface of the thick wall portion 11'. Screw holes 16 are also formed in the side surface 10 of the bottom wall 13. These screw holes 15, 16 are used as holes for inserting screws for attaching the side cap 9 to both ends in the longitudinal direction of the storage body 8.

  A concave portion 17 is formed in the lower portion of the bottom wall 13 downward. The concave portion 17 is formed as a concave groove over the entire length in the lateral width direction of the auxiliary storage portion 1, functions as a handle for the drawer storage portion 4, and pulls the drawer storage portion 4 and the storage body 8 forward. Sometimes the user can reach out.

  The back wall 14 is screwed and fixed to the back surface of the front surface portion 5 of the drawer storage portion 4, whereby the auxiliary storage portion 1 is attached to the front surface portion 5 of the drawer storage portion 4. The upper end of the back wall 14 is formed to be located slightly above the bottom wall 13.

  As shown in FIGS. 2 (a), 2 (b), and 3 (a), the back side of the front wall 11 of the storage body 8 is downward from the thick wall portion 11 'along the front wall 11 with a gap. A rib portion 20 extending in the direction is formed. The rib portion 20 is formed so as to be integrated with the front wall 11 at an intermediate portion 21 and a lower end portion 22 in the vertical direction. The intermediate part 21 of the rib part 20 is thin, but the lower end part 22 is formed thick.

  FIG. 5 shows a configuration in which the groove portions 28 and 33 to be described later are not formed, although the configuration is almost the same as that of the auxiliary storage portion 1 of the present invention. Referring to FIG. 5, the lower end portion 22 of the rib portion 20 is thick at the location where the lower end portion 22 of the rib portion 20 is coupled to the front wall 11 when the storage body 8 is extruded. As a result, the resin of the front wall 11 is drawn into the thick lower end 22 side, and as shown in FIGS. 5 (a) and 5 (b), the position corresponding to the lower end 22 of the rib 20 is Sink marks (dents) 24 are formed in a distorted shape along the longitudinal direction of the lower end portion 22 on the substantially vertical elevation surface of the surface portion 23 serving as the decorative surface of the wall 11.

  As shown in FIGS. 5A and 5B, a similar phenomenon occurs at the position on the surface side of the inclined wall 12 corresponding to the bottom wall front end portion 25 where the bottom wall 13 is coupled to the inclined wall 12. Also occurs. That is, linear sink marks 27 are also generated at positions corresponding to the bottom wall front end portion 25 on the vertical surface 26 inclined at a predetermined angle from the vertical direction of the surface portion 23 in the same manner as the position corresponding to the rib portion 20. End up.

  The phenomenon in which these sink marks 24 and 27 occur is caused by the lower end portion 22 and the bottom wall 13 of the rib portion 20 being relatively thick and having a large amount of pull-in during extrusion molding. Since 21 is thin, sink marks are unlikely to occur on the elevation surface of the front wall 11 corresponding to the intermediate portion 21, and even if it occurs, it is very inconspicuous.

  Therefore, the present invention employs the following characteristic configuration. That is, it is located on the vertical surface of the surface portion 23 of the front wall 11 corresponding to the lower end portion 22 of the rib portion 20, and FIGS. 2 (a), 2 (b), 3 (a), 3 (b), As shown in (d), it was formed in a groove portion 28 extending horizontally in a straight line in the longitudinal direction of the auxiliary storage portion 1. As shown in an enlarged view of the cross section in FIG. 3D, the groove portion 28 includes an upper surface portion 29 formed in a substantially horizontal direction and an inclined surface portion 30 connected from the upper surface portion 29 to the surface portion 23. It is formed as a substantially right triangle.

  In order to form such a groove 28, a triangular projection that forms the groove having the above-described shape may be formed on the inner surface of an extrusion mold. In addition, when molding a resin molded product by injection molding, it is possible to form a texture on the surface portion so as to make the sink mark inconspicuous, but in the case of extrusion molding, such a texture cannot be formed. Therefore, it is effective to form a groove as in the present invention.

  By the way, when the user looks at the auxiliary storage unit 1 from the front surface (front side), usually, as shown in FIG. Thus, when the user looks down, the groove portion 28 is formed in a substantially right triangle as described above. Therefore, the upper edge 31 on the straight surface side of the upper surface portion 29 can be clearly seen. The inclined surface portion 30 of the front wall 11 does not stand out as if it is assimilated with the surface portion 23 of the front wall 11, and as a whole, only the straight line of the upper edge 31 of the groove portion 28 can be seen well and looks good. Become.

  If the groove portion 28 is formed so that its upper surface portion 29 is located above the upper end of the range 32 of the sink marks 24 (see FIG. 3 (d)) that is expected to occur during molding, The edge 31 is clearly formed on the surface portion 23, and a neat effect is produced in terms of design.

  The reason is that if the upper surface portion 29 is formed so as to be positioned below the upper end of the sink mark 24 that is expected to occur during molding, at least a part of the sink mark 24 is located above the straight front edge 31 of the upper surface portion 23. Is exposed, and the effect on the linear design of the front edge 31 of the upper surface portion 29 at the folding angle is greatly reduced.

  In addition, it is preferable that the inclined surface portion 30 of the groove portion 28 is also formed so as to completely cover the sinkable range 32 in the vertical direction by causing the lower end thereof to be positioned below the lower end of the sink.

  However, since the inclined surface portion 30 is gradually connected to the surface portion 23 by the taper surface, the lower end is formed slightly above the lower end of the sink 24, and the sink 24 is partially formed by the inclined surface portion. Even if it appears below the lower end of 30, the degree of reduction of the design effect is not so much as compared with the case where a part of the sink mark 24 appears above the linear front edge 31 of the upper surface portion 29.

  As for the shape of the groove 28, various shapes can be considered as shown in FIGS. 3 (e) to 3 (g) in addition to a substantially right-angled triangle cross section. In the shape of the groove portion, the upper and lower edges of the groove portion make it possible to see two upper and lower straight edge portions, and the appearance is not necessarily better than the groove portion having a substantially right-angled cross section shown in FIG. .

  In the present invention, the groove portion is also formed at a position corresponding to the bottom wall 13 corresponding to the rib portion 20 with respect to the occurrence of sink marks. That is, the position on the surface side of the inclined wall 12 corresponding to the bottom wall front end portion 25 (where the bottom wall 13 is coupled to the inclined wall 12) (corresponding to the position corresponding to the rib portion of the surface portion of claim 2). In the same manner as the surface portion 23 of the front wall 11, a linear groove portion 33 is formed in the longitudinal direction on the vertical surface 26 inclined at a predetermined angle from the vertical direction of the surface portion 23 to the back side. The groove 33 also includes an upper surface portion 34 formed in a substantially horizontal direction, and an inclined surface portion 35 connected from the upper surface portion to the surface portion of the inclined wall 12.

  The side cap 9 includes a cap body 18 (see FIGS. 4A and 4B) and a cap cover 19 (see FIG. 4C). The cap body 18 is attached to the side surfaces 10 of both ends in the longitudinal direction of the storage body 8 of the auxiliary storage portion 1 by being fixed with screws and closes the openings at both ends in the longitudinal direction of the auxiliary storage portion 1. Is.

  The cap cover 19 is fitted from the outside so as to cover the cap body 18, engages the locking claw 36 of the cap body 18 and the two engagement pieces 37 of the cap cover 19, and further, the lower edge of the cap body 18 is engaged. It is fixed by engaging with the engaging protrusion 38 of the cap cover 19. As a result, as shown in FIG. 4D, the side caps 9 are attached to the respective side surfaces 10 at both ends in the longitudinal direction of the storage body 8.

  Further, as shown in FIGS. 1A and 1B, the auxiliary storage portion is projected forward from the front ends of the side plates 6 on both the left and right sides of the cabinet 2 above the auxiliary storage portion 1 and below the top plate 3. A support bar 39 is provided to close the upper surface opening of 1.

  The support bar 39 includes a horizontal portion 40 and a bent portion 41. A base end portion of the horizontal portion 40 is fixed to the left and right side plates 42 on both sides of the cabinet 2, and a support bar 39 is attached to the cabinet 2. The support bar 39 closes the upper surface opening of the auxiliary storage unit 1 and has two functions as a drooling bar that can be drowned by the user.

As mentioned above, although the best form for implementing the cabinet provided with the storage main body formed with the resin molded product which concerns on this invention was demonstrated based on the Example, this invention is limited to such an Example. However, it goes without saying that there are various embodiments within the scope of the technical matters described in the claims.
