Description

この発明は、上下のシート体で周期的形状を有する縦壁部材を挟んで一体に成型された熱可塑性合成樹脂製ボード（いわゆる段ボールプラスチック）を、荷室底面部材として用いるような自動車の荷室構造に関する。 The present invention relates to a cargo compartment of an automobile in which a thermoplastic synthetic resin board (so-called cardboard plastic) integrally molded with a vertical wall member having a periodic shape between upper and lower sheet bodies is used as a cargo compartment bottom member. Concerning structure.

上述例の上下のシート体で周期的形状を有する縦壁部材を挟んで一体に成型された熱可塑性合成樹脂製ボードいわゆる段ボールプラスチックは、強度と低質量に優れた板状材であって、その上面に不織布を貼着したものが、自動車の荷室フロアボードとして広く採用されている。 The so-called corrugated plastic board made of a thermoplastic synthetic resin integrally molded with the vertical wall member having a periodic shape between the upper and lower sheet bodies in the above example is a plate-like material excellent in strength and low mass, What stuck the nonwoven fabric on the upper surface is widely adopted as a luggage floor board for automobiles.

しかしながら、上述の段ボールプラスチックは所定の厚さをもち、その端部（つまり断面部）を見せないようにし、該端部に起因する段差を荷室底面に現さないようにするため、その端部がセダン型車両の荷室底面周縁部に略合致するように段ボールプラスチックの平面形状を工夫して採用することが殆どであった。
一方で、ワゴン型自動車では、後席シートバックを前方へ倒伏させて荷室を拡大した時に、荷室底面部のフラット化（平坦化）を確保する目的で、後席シートと、開閉可能な荷室フロアボードとの間にかさ上げ部材を備えている。 However, the above-mentioned corrugated plastic has a predetermined thickness, so that the end portion (that is, the cross-sectional portion) is not shown and the step caused by the end portion does not appear on the bottom surface of the cargo compartment. In most cases, however, the flat shape of the corrugated cardboard plastic is devised so that it substantially matches the peripheral edge of the bottom of the luggage compartment of the sedan type vehicle.
On the other hand, in a wagon-type vehicle, when the rear seat is folded forward and the cargo compartment is enlarged, the rear seat can be opened and closed for the purpose of ensuring flattening of the bottom of the cargo compartment. A lifting member is provided between the cargo floor board.

本発明者等は、従来、樹脂ブロー成形品であるかさ上げ部材を軽量化するため、近年注目されているポリスチレン・ポリオレフィン複合樹脂発泡体でかさ上げ部材を形成し、該かさ上げ部材のみでは、その表面の機械的強度が弱いので、ポリスチレン・ポリオレフィン複合樹脂発泡体から成るかさ上げ部材の上面部を段ボールプラスチックで覆うことを検討した。
しかし、この構成では段ボールプラスチックの端部が荷室底部を横切ることになるので、段ボールプラスチックの端部の段差を如何にして解消するかが問題となる。 In order to reduce the weight of a raised member that is a resin blow molded product, the inventors of the present invention formed a raised member with a polystyrene / polyolefin composite resin foam that has been attracting attention in recent years. Since the mechanical strength of the surface is weak, it was studied to cover the upper surface of the raised member made of polystyrene / polyolefin composite resin foam with corrugated cardboard plastic.
However, in this configuration, since the end of the corrugated plastic crosses the bottom of the cargo compartment, it becomes a problem how to eliminate the step at the end of the corrugated plastic.

ところで、特許文献１にはワゴン荷室に樹脂製のかさ上げ部材（荷室ボード参照）を設けた構造が開示されているが、該特許文献１には、かさ上げ部材と段ボールプラスチックとの組合せについては全く開示されておらず、その示唆もない。
また、特許文献２には、ブロー成形ボード（基材参照）と段ボールプラスチック（表皮材参照）とを組合せる構造が開示されているが、該特許文献２においては、段ボールプラスチックをブロー成形ボード自体の接着力により該ブロー成形ボードに接着するものであって、基本的構成が本発明とは全く異なるものである。 By the way, Patent Document 1 discloses a structure in which a resin raising member (refer to a loading board) is provided in a wagon luggage compartment. However, Patent Document 1 discloses a combination of a raising member and corrugated plastic. Is not disclosed at all, nor is it suggested.
Further, Patent Document 2 discloses a structure in which a blow molded board (refer to a base material) and a corrugated cardboard plastic (refer to a skin material) are combined, but in Patent Document 2, corrugated plastic is used as a blow molded board itself. The basic structure is completely different from that of the present invention.

このように、上記実施例の自動車の荷室構造は、リヤフロア２上に載置され、その上面部が平面状である樹脂発泡体から成るかさ上げ部材４１と、該かさ上げ部材４１の上面部４１ａに合致して配置され上下のシート体４６，４７で周期的形状を有する縦壁部材４５を挟んで一体に成型された樹脂ボード４２とを含んで成り、上記かさ上げ部材４１の上面部４１ａに上方開口した直線状の細溝部４１ｈが形成され、上記樹脂ボード４２が下向きに折曲された端部４２ａを有し、該端部４２ａが上記細溝部４１ｈに差し込まれることによって上記樹脂ボード４２と上記かさ上げ部材４１とが係合されており、上記樹脂ボード４２の上面部が荷室２１の底面部を成すものである（図２，図９，図１０参照）。 As described above, the cargo compartment structure of the automobile according to the above embodiment includes a raised member 41 made of a resin foam that is placed on the rear floor 2 and has a flat upper surface, and an upper surface of the raised member 41. 41a, and a resin board 42 formed integrally with a vertical wall member 45 having a periodic shape between upper and lower sheet bodies 46 and 47, and an upper surface portion 41a of the raising member 41. The resin board 42 has an end portion 42a bent downward, and the end portion 42a is inserted into the narrow groove portion 41h. And the raising member 41 are engaged, and the upper surface portion of the resin board 42 forms the bottom surface portion of the cargo compartment 21 (see FIGS. 2, 9, and 10).

この構成によれば、樹脂ボード４２の下向きに折曲された端部４２ａを、かさ上げ部材４１の弾性性質を利用して、その上方開口の細溝部４１ｈに差し込んで該樹脂ボード４２とかさ上げ部材４１とを係合するので、軽量かつ表面強度に優れた荷室２１のかさ上げ構造体（かさ上げ部材４１と樹脂ボード４２とを組合せたもの）が得られ、樹脂ボード４２とかさ上げ部材４１との組立も容易にすることができると共に、樹脂ボード４２の端部４２ａの隠ぺいと、通常の端部処理省略も可能とすることができる。
また、上記樹脂ボード４２の上面部には、マット材４８が上記下向きに折曲された端部４２ａまで貼着されており、該端部４２ａが上記マット材４８と共に、上記かさ上げ部材４１の細溝部４１ｈに差し込まれたものである（図９，図１０参照）。 According to this configuration, the end portion 42a bent downward of the resin board 42 is inserted into the narrow groove portion 41h of the upper opening by utilizing the elastic property of the raising member 41, and the resin board 42 is raised. Since the member 41 is engaged, a raised structure (a combination of the raised member 41 and the resin board 42) of the luggage compartment 21 that is lightweight and excellent in surface strength is obtained, and the resin board 42 and the raised member are obtained. Assembling with 41 can be facilitated, and concealment of the end portion 42a of the resin board 42 and normal end portion processing can be omitted.
Further, the mat member 48 is attached to the upper surface portion of the resin board 42 up to the end portion 42a bent downward, and the end portion 42a together with the mat member 48 of the raising member 41 is attached. It is inserted into the narrow groove portion 41h (see FIGS. 9 and 10).

この構成によれば、樹脂ボード４２の上面部にその端部４２ａまでマット材４８を貼着し、マット材４８と共に樹脂ボード４２を下向きに折曲げることにより、折り曲げ角部をマット材４８で化粧することができ、また本来は樹脂ボード４２の表面は円滑面で差し込み係合力が小さいものを、マット材４８の摩擦力により樹脂ボード４２の細溝部４１ｈに対する係合力を増大させることができ、両者（かさ上げ部材４１と樹脂ボード４２）の一体化を図ることができる。
さらに、上記かさ上げ部材４１の後方に、荷室２１後方の荷室底面部（荷室フロア部２６参照）を成すフロアボード２５が配置され、上記かさ上げ部材４１はその後端部に上面部４１ａより所定高さ低く車幅方向に延在して上記フロアボード２５の前端部を載置する棚部（ボード前方載置部４１ｂ参照）を有し、該棚部（ボード前方載置部４１ｂ）の直前に上記細溝部４１ｈが形成され、上記フロアボード２５が上記棚部（ボード前方載置部４１ｂ）に載置されたとき、フロアボード２５の上面部の高さよりも、上記マット材４８が貼着された樹脂ボード４２の差し込み部（端部４２ａ参照）の上面部の高さが低く設定されたものである（図２，図１０参照）。 According to this configuration, the mat member 48 is adhered to the upper surface portion of the resin board 42 up to the end portion 42 a, and the resin board 42 is bent downward together with the mat member 48, so that the bent corner portion is decorated with the mat member 48. In addition, since the surface of the resin board 42 is smooth and the engagement force is small, the engagement force with respect to the narrow groove portion 41h of the resin board 42 can be increased by the frictional force of the mat member 48. Integration of (raising member 41 and resin board 42) can be achieved.
Furthermore, a floor board 25 forming a cargo compartment bottom portion (see cargo compartment floor portion 26) at the rear of the cargo compartment 21 is disposed behind the raising member 41, and the elevation member 41 has an upper surface portion 41a at the rear end thereof. It has a shelf (see the board front placement portion 41b) that extends in the vehicle width direction to be lower than the predetermined height and places the front end of the floor board 25, and the shelf (board front placement portion 41b). When the narrow groove portion 41h is formed immediately before the floor board 25 is placed on the shelf portion (board front placement portion 41b), the mat member 48 is more than the height of the upper surface portion of the floor board 25. The height of the upper surface portion of the insertion portion (see the end portion 42a) of the stuck resin board 42 is set low (see FIGS. 2 and 10).

この構成によれば、マット材４８が貼着された樹脂ボード４２の差し込み部（端部４２ａ参照）の上面部（いわゆる角部）の高さがフロアボード２５の上面部の高さよりも低くなるよう設定したので、ワゴン車両において荷物を荷室底面に摺って出し入れする場合であっても、荷物の底面で樹脂ボード４２の上記角部が摺動力により損傷するのを防止することができる。
加えて、上記実施例で開示したように、マット材４８を含む樹脂ボード４２の端部４２ａにおける前後方向の幅を、かさ上げ部材４１の細溝部４１ｈにおける前後方向の幅よりも大きく設定すると（図９，図１０参照）、樹脂ボード４２の細溝部４１ｈに対する係合力をさらに増大させることができる。 According to this configuration, the height of the upper surface portion (so-called corner portion) of the insertion portion (see the end portion 42 a) of the resin board 42 to which the mat material 48 is adhered is lower than the height of the upper surface portion of the floor board 25. Thus, even if the load is slid into and out of the bottom of the luggage compartment in the wagon vehicle, the corners of the resin board 42 can be prevented from being damaged by the sliding force on the bottom of the load.
In addition, as disclosed in the above embodiment, when the width in the front-rear direction at the end 42a of the resin board 42 including the mat member 48 is set larger than the width in the front-rear direction at the narrow groove 41h of the raising member 41 ( The engagement force of the resin board 42 with respect to the narrow groove portion 41h can be further increased.
