Description

  The present invention relates to a luggage board, which is a lid of a concave storage box formed on a cargo compartment floor at the rear of a vehicle, and has a thin and light board thickness and excellent strength and rigidity. is there.

  Wagon-type and minivan-type cars have a space for loading luggage at the rear of the rear seat, and the luggage compartment floor has a concave storage box that can be opened and closed as a lid. Has a luggage board.

  Since the luggage board for automobiles is a lid of the concave storage box and becomes a part of the cargo floor, it needs to be excellent in strength and rigidity. It lacked strength and rigidity.

Resin-made automotive luggage boards have been introduced in Japanese Patent Application Laid-Open Nos. 2000-108793 and 2000-52874, but since both of them are made of solid boards, the board thickness is increased. However, the strength and rigidity are not so high, and the luggage board for automobiles cannot be provided with the required strength and rigidity. A blow molded hollow double wall molded product in which an inner rib is formed in the hollow portion is described in JP-A-7-214643.

A plurality of inner ribs, which are plate-like ribs connecting the back wall and the front wall facing the front wall, are formed in parallel on the high surface of the back wall before the high and low step parts, and straddle the high and low step parts. In addition, by forming a slit rib, which is a rib opened to the back wall side by recessing a part of the back wall so as to connect to the inner rib, it is lightweight even if the board thickness is thin, and it is also strong and rigid The purpose is to provide an excellent luggage board for automobiles.

In order to achieve the object, the present invention provides an automobile luggage board according to claims 1 to 4. That is, the automotive luggage board according to claim 1 is an automotive luggage board made of a resin panel having a hollow double wall structure having a front wall and a back wall, and the back wall of the resin panel has a height difference. It is formed on the high and low surfaces, and the hollow part of the resin panel is a plate-shaped rib that connects the back wall and the front wall facing the front wall over the high surface of the back wall before the high and low stepped parts. A plurality of inner ribs are formed in parallel, and a slit rib, which is a rib opened to the back wall side, is formed by recessing a part of the back wall so as to straddle the height difference and connect to the inner rib. It is characterized by being formed.

  The luggage board for automobiles according to claim 2 is the structure of claim 1, wherein the back wall of the resin panel has a lower surface on the entire periphery or a part of the periphery, and a higher surface on the inner side of the lower surface. It is characterized by this.

  The luggage board for automobiles according to claim 3 is characterized in that, in the configuration of claim 1 or 2, the slit rib forms a recessed portion closed with respect to the outer peripheral surface of the resin panel.

  According to a fourth aspect of the present invention, there is provided the automotive luggage board according to the first or second aspect, wherein the slit rib has a concave portion opened on the outer peripheral surface of the resin panel.

According to the present invention, the back wall of the resin panel is formed on a high surface and a low surface that make a difference in height, and the hollow portion of the resin panel is formed on the high surface of the back wall in front of the high and low stepped portions. A plurality of inner ribs, which are plate-like ribs connecting the back wall and the front wall facing the wall, are formed in parallel, and part of the back wall is recessed so as to straddle the height steps and connect to the inner rib By forming slit ribs that are recessed and open on the back wall side, it is possible to obtain an automobile luggage board that is lightweight even when the board thickness is thin and that is excellent in strength and rigidity.

  1 is a perspective view of an automotive luggage board according to an embodiment of the present invention as seen from the back side, FIG. 2 is a cross-sectional view of the same, FIG. 3 is a perspective view of a part of the same, and FIG. 4 is another embodiment of the present invention. FIG. 5 is a partial perspective view of the same, and FIG. 6 is a perspective view of the automobile showing a usage mode of the automotive luggage board according to the present invention.

  1 to 3, reference numeral 1 denotes a luggage board. The luggage board 1 is composed of a resin panel 4 having a hollow double wall structure having a front wall 2 and a back wall 3, and the back wall 3 is opposed to the front wall 2 with a space therebetween. A hollow portion 5 is formed between the wall 3 and the wall 3.

  The luggage board 1 is formed by forming the back wall 3 of the resin panel 4 on a high surface 6 and a low surface 7 that make a height difference, and in the hollow portion 5 of the resin panel 4, the height difference of the back wall 3. A plurality of inner ribs 9 facing the front wall 2 are formed in parallel with the portion 8, and slit ribs 10 are formed so as to straddle the height difference steps 8 and connect to the inner rib 9.

The low surface 7 of the back wall 3 of the resin panel 4 is formed in front of the back wall 3 and around the left and right sides, and the inside of the low surface 7 is a high surface 6. Further, the slit rib 10 forms a recessed portion closed with respect to the outer peripheral surface of the resin panel 4. Shafts 11 and 11 are provided at the front left and right ends of the luggage board 1, respectively. The luggage board 1 is attached by the shafts 11 and 11 so that a concave storage portion (not shown) can be opened and closed. is there.

  4 and 5 relate to another embodiment of the present invention, in which the slit rib 10 formed in the back wall 3 is formed as a recess opened on the outer peripheral surface of the resin panel 4. In addition, since the other structure is equivalent to what was shown in FIG. 1 thru | or FIG. 3, the same code | symbol is attached | subjected to the same component and the description is abbreviate | omitted.

  The luggage board 1 according to the present invention is made of a blow-moldable thermoplastic resin such as an ABS resin, a modified polyphenylene oxide resin, a polycarbonate resin, a polyamide resin, a polypropylene resin, or a polyethylene resin.

  As shown in FIG. 6, the luggage board 1 according to the present invention is provided in a concave storage box of the cargo compartment floor 13 of the automobile 12, and the luggage board 1 serves as a lid of the storage box and is closed in the luggage compartment.
