Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a synthetic resin drawer suitable as an internal drawer of built-in furniture called system furniture.

(Prior Art) A conventional drawer of this type in which reinforcing ribs are formed on the lower surface of the bottom wall is known.

(Disadvantages of the Prior Art) The conventional drawer has the following disadvantages. In other words, since reinforcing ribs are formed on the lower surface of the bottom wall, the time and conditions from high temperature to room temperature after completion of molding are likely to be different between the areas where reinforcing ribs are formed and the areas where they are not. However, there was a drawback that a slightly depressed groove pattern along the reinforcing ribs appeared on the top surface of the bottom wall, resulting in an unsightly appearance.

(Purpose of the invention) The purpose of this invention is to eliminate the above-mentioned drawbacks based on an extremely unique idea.

(Example) This invention will be described below based on an example shown in the drawings.

As shown in FIG. 1, a drawer 1 made of synthetic resin (note that "made of synthetic resin" includes those that are not partially made of synthetic resin) has a bottom wall 2, left and right side walls 3,
It has a front wall 4 and a rear wall 5. An upwardly open opening 6 is formed in the center of the front wall 4, a glass plate retaining groove 7 is formed at the periphery of the opening 6, and a transparent, translucent or opaque glass plate 8 is formed in the glass plate retaining groove 7. is fastened. A downwardly opened recess 9 is formed in each of the left and right parts 4a of the front wall 4,
These recesses 9 can be used as handle recesses for pulling the drawer 1. The left and right side walls 3 are formed with projecting edges 10 that are clearly shown in FIG.

A plurality of endless reinforcing ribs 11 are integrally formed on the lower surface 2b of the bottom wall 2. It goes without saying that the shape of the portion defined by these reinforcing ribs 11 is not limited to that shown in the drawings.
As clearly shown in FIG. 4, a slightly protruding pattern-like convex portion 13 is integrally formed on the upper surface 2a of the portion of the bottom wall 2 surrounded by the center line 12 of these reinforcing ribs 11. Note that the convex portion 13 is at least a portion surrounded by the inner circumferential surface 11a of the reinforcing rib 11,
It may be formed in a portion of the bottom wall upper surface 2a that is below the portion surrounded by the outer circumferential surface 11b. A fine uneven pattern 14 is formed on the upper surface of these convex portions 13 by processing such as matte finishing or graining.

Note that the resin injection port of the drawer mold is formed in a portion forming the bottom wall lower surface 2b surrounded by the reinforcing ribs 11, so as shown in FIG.
The exit trace 15 is located on the lower surface 2 of the bottom wall where the convex portion 13 is formed.
It will remain in b. Therefore, because of the convex portion 13 and the fine uneven pattern 14 on its upper surface, these exit hole traces 15 do not appear on the bottom wall upper surface 2a to the extent that they degrade the appearance or at all.

(How to use the embodiment) This drawer 1 is used as an internal drawer of built-in furniture, that is, an internal drawer that is hidden by the door of the furniture, but it can also be used as an ordinary drawer or as a drawer other than furniture. Needless to say, it can be used.

(Effect of the invention) As described above, according to this invention, the upper surface of the bottom wall 2 of the portion surrounded by the endless reinforcing ribs 11
Convex portions 13 are formed on a, and these convex portions 13
Since these convex portions 13 are designed to catch people's attention, the groove pattern appearing along the reinforcing ribs 11 can be made inconspicuous and the appearance of the drawer 1 can be improved.
