Description

本発明は、折り畳み型ボード及びこの折り畳み型ボードを備えた自動車に関する。   The present invention relates to a foldable board and an automobile provided with the foldable board.

従来、この種の折り畳み型ボードに関しては、例えば、下記特許文献１に記載のボード成形品が提案されている。このボード成形品は、フラット状の芯材と、この芯材の表面側に一体貼付された表皮材とにより構成されており、このボード成形品には、２分割に折り畳み可能なようにヒンジ部が設けられている。   Conventionally, for this type of folding board, for example, a board molded product described in Patent Document 1 has been proposed. This board molded product is composed of a flat core material and a skin material integrally attached to the surface side of the core material. The board molded product has a hinge portion so that it can be folded in two. Is provided.

ここで、ヒンジ部は、ボード成形品の折れ線に沿って延びるように芯材に設けた支持凸条と、この支持凸条の両側に表皮材とは反対側から肉抜きされた両凹溝と、ヒンジ中心となるように両凹溝内で支持凸条寄りに設けられた細溝とによって、構成されている。   Here, the hinge portion is a support ridge provided on the core material so as to extend along the broken line of the board molded product, and both concave grooves formed on both sides of the support ridge from the opposite side of the skin material. The narrow groove provided near the support ridge in the both concave grooves so as to be the hinge center.

このように構成したボード成形品は、支持凸条を中心として、芯材を表皮材とともに表皮材の表面側へ或いは裏面側へ折り畳まれるようになっている。   The board molded product configured in this way is configured to fold the core material together with the skin material to the front surface side or the back surface side with the support ridge as the center.

特許第３７５０９０２号公報Japanese Patent No. 3750902

ところで、上述のボード成形品によれば、支持凸条が芯材の折り畳み方向に対する法線方向に幅を有することから、支持凸条の両側の各表皮材部分は、芯材の厚みのために、当該各表皮材部分の間の折り畳み状態は、きちんとした折り畳み状態になり易いものの、芯材を表皮材とともに表皮材の表面側に向け折り畳んだとき、表皮材のうち支持凸条の両側の各表皮材部分の間に隙間ができてしまい、当該各表皮材部分をきちんとした折り畳み状態にすることができない。   By the way, according to the above-mentioned board molded product, since the support ridge has a width in the normal direction to the folding direction of the core material, each skin material part on both sides of the support ridge is for the thickness of the core material. The folded state between the respective skin material portions is likely to be a neatly folded state, but when the core material is folded together with the skin material toward the surface side of the skin material, A gap is formed between the skin material portions, and the respective skin material portions cannot be properly folded.

そこで、本発明は、以上のようなことに対処するため、ヒンジ構造に工夫を凝らし、両面側のいずれの方向にもきちんと折り畳み可能な折り畳み型ボード及びこの折り畳み型ボードを備えた自動車を提供することを目的とする。   In view of the above, the present invention provides a foldable board that can be folded properly in either direction on both sides and a vehicle equipped with this foldable board in order to deal with the above-described problems. For the purpose.

上記課題の解決にあたり、本発明に係る折り畳み型ボードは、請求項１の記載によれば、
互いに表面に沿う方向に順次配列されて所定のボード材料からなる複数のボード部材（６０ａ、６０ｂ）と、
当該複数のボード部材のうち互いに隣接する両ボード部材ごとに当該両ボード部材を相互に表面側或いは裏面側へ折り畳み可能に連結する少なくとも２つのヒンジ手段（６０ｅ、６０ｆ、６０ｇ、６０ｈ）とを備える。 In solving the above-mentioned problem, the folding board according to the present invention, according to the description of claim 1,
A plurality of board members (60a, 60b) which are sequentially arranged in a direction along the surface and made of a predetermined board material;
At least two hinge means (60e, 60f, 60g, 60h) are provided for each of the board members adjacent to each other among the plurality of board members so as to foldably connect the board members to the front side or the back side. .

そして、当該２つのヒンジ手段は、それぞれ、両ボード部材の各対向縁部を介し両ボード部材の一方の表面と他方のボード部材の裏面との間に接続される第１の伸縮不能な柔軟性ヒンジ部材（６０ｅ、６０ｇ）と、両ボード部材の上記各対向縁部を介し一方のボード部材の裏面と他方のボード部材の表面との間に接続される第２の伸縮不能な柔軟性ヒンジ部材（６０ｆ、６０ｈ）とにより構成されている。   And the said 2 hinge means is respectively 1st non-stretchable softness | flexibility connected between the one surface of both board members, and the back surface of the other board member via each opposing edge part of both board members. The second non-stretchable flexible hinge member connected between the hinge member (60e, 60g) and the back surface of one board member and the surface of the other board member via the opposing edge portions of both board members (60f, 60h).

これにより、当該折り畳み型ボードを、例えば、一般家屋の台所や自動車の車室内の床に形成した開口部に嵌装される収納庫の開口部内に着脱可能に嵌装すれば、当該折り畳み型ボードは、上記床の床部材を兼用しつつ、収納庫の蓋としての役割を果たす。   Thus, if the foldable board is detachably fitted into an opening of a storage box that is fitted into an opening formed in a floor of a kitchen of a general house or an automobile, for example, the foldable board Serves as a lid for the storage while also serving as a floor member of the floor.

このような状態において、収納庫内の収容物を取り出したり、或いは、他の物を収納庫内に収納するにあたっては、ボードを、２つのヒンジ手段を介し折り畳む。   In such a state, the board is folded via the two hinge means when taking out the contents in the storage or storing other things in the storage.

しかして、ボードをその表面側へ折り畳むにあたっては、両ボード部材のいずれか一方のボード部材を他方のボード部材に向けてその表面側から回動させて、収納庫の開口部の開口部分を開く。一方、ボードをその裏面側から折り畳むにあたっては、両ボード部材のいずれか一方のボード部材を他方のボード部材に向けてその裏面側から回動させて、収納庫の開口部の開口部分を開く。その結果、収納庫内の収容物を取り出したり、或いは、他の物を収納庫内に収納することができる。   Thus, when folding the board to the surface side, either one of the board members is turned toward the other board member from the surface side to open the opening of the opening of the storage. . On the other hand, when the board is folded from the back side, either one of the board members is turned toward the other board member from the back side to open the opening of the opening of the storage. As a result, the stored items in the storage can be taken out, or other items can be stored in the storage.

然る後、一方のボード部材により、上記２つのヒンジ手段を介し、収納庫の開口部の開口部分を閉塞すると、ボードは、再び、床の床部材を兼用しつつ収納庫に対する蓋としての役割を果たす。   After that, when one of the board members closes the opening of the opening of the storage through the two hinge means, the board again serves as a lid for the storage while also using the floor member of the floor. Fulfill.

ここで、上述のような構成を有する２つのヒンジ手段の各々によれば、伸縮不能で柔軟性を有する第１及び第２のヒンジ部材が、両ボード部材の各対向縁部に沿う方向からみて両ボード部材間にて互いに交差するように連結されていることとなる。   Here, according to each of the two hinge means having the above-described configuration, the first and second hinge members that cannot be expanded and contracted and have flexibility are viewed from the direction along the opposing edge portions of both board members. It will be connected so that it may mutually cross between both board members.

このため、上述のように、ボードをその表面側から折り畳む際に、両ボード部材のいずれか一方のボード部材を他方のボード部材に向けてその表面側から回動させるとき、いずれか一方のボード部材は、両ボード部材の各表面の対向表面部位を中心として他方のボード部材に向けてその表面側から回動する。従って、いずれか一方のボード部材は、その表面にて、他方のボード部材の表面に重なるように１８０°回動する。一方、両ボード部材のいずれか一方のボード部材を他方のボード部材に向けてその裏面側から回動させるとき、両ボード部材をその各対向縁部側から上方へ傾斜状に持ち上げた状態にて、いずれか一方のボード部材を、両ボード部材の各裏面の対向裏面部位を中心として他方のボード部材に向けてその裏面側から回動させる。従って、いずれか一方のボード部材は、その裏面にて、他方のボード部材の裏面に重なるように１８０°回動する。   For this reason, as described above, when folding the board from the surface side, when turning one of the board members toward the other board member from the surface side, one of the boards The member rotates from the surface side toward the other board member around the opposing surface portion of each surface of both board members. Accordingly, one of the board members rotates 180 ° on the surface so as to overlap the surface of the other board member. On the other hand, when either one of the board members is rotated from the back side toward the other board member, both the board members are lifted upward from the respective opposing edge portions in an inclined manner. Then, one of the board members is rotated from the back surface side toward the other board member around the opposite back surface portion of each back surface of both board members. Therefore, one of the board members rotates 180 ° on the back surface so as to overlap the back surface of the other board member.

このことは、ボードは、その表面側或いは裏面側への折り畳みにあたり、他方のボード部材を３６０°という広い角度範囲以内にて回動させ得ることを意味する。その結果、収納庫内の収容物を取り出したり、或いは、他の物を収納庫内に収納するにあたり、ボードを表面側及び裏面側のいずれに向けて折り畳んでも、収納庫の開口部の開口部分を十分に開くことができて、便利である。   This means that when the board is folded to the front side or the back side, the other board member can be rotated within a wide angle range of 360 °. As a result, when taking out the contents in the storage or storing other objects in the storage, the opening part of the opening of the storage can be folded even if the board is folded toward either the front side or the back side. Can be fully opened and convenient.

ここで、上述のごとく、各ヒンジ部材は、伸縮不能で柔軟性を有することから、ボードをその表面側或いは裏面側に向けて折り畳む際には、他方のボード部材が、両ボード部材の各表面の対向表面部位或いは各裏面の対向裏面部位の間に間隙を形成することなく、当該各表面の対向表面部位或いは各裏面の対向裏面部位を基準に回動することができる。従って、ボードをその表面側或いは裏面側への折り畳みが円滑になされ得る。   Here, as described above, since each hinge member cannot be stretched and has flexibility, when the board is folded toward the front surface side or the back surface side, the other board member is attached to each surface of both board members. It is possible to rotate with reference to the opposing surface portion of each surface or the opposing back surface portion of each back surface without forming a gap between the opposing surface portions or the opposing back surface portions of each back surface. Therefore, the board can be smoothly folded to the front side or the back side.

In this embodiment, both glass fiber mats M1 and M2 are formed by consolidating glass fibers cut to a length within 50 to 100 (mm) with a binder and molding them into sheets. . Both glass fiber mats M1 and M2 formed in this way are lightweight and have a characteristic of being strong against stress in a direction perpendicular to the thickness direction of the honeycomb body M3.

また、ハニカム体Ｍ３は、所定の厚さの板状紙製ハニカム体からなるもので、このハニカム体Ｍ３は、複数の紙片を、相隣り合う両紙片毎に、順次所定間隔にて接着した上で、多数の六角形状の開孔部を形成するように紙片の厚さ方向に広げて、形成されている。このように形成したハニカム体Ｍ３は、軽量で、その厚さ方向に作用する応力に対し強いという特性を有する。   The honeycomb body M3 is made of a plate-like paper honeycomb body having a predetermined thickness. The honeycomb body M3 is formed by sequentially bonding a plurality of paper pieces to each adjacent two paper pieces at predetermined intervals. Thus, it is formed by expanding in the thickness direction of the paper piece so as to form a large number of hexagonal apertures. The honeycomb body M3 formed in this manner is lightweight and has a characteristic that it is strong against stress acting in the thickness direction.

しかして、ボード材料Ｍは、上述のように形成した両ガラス繊維マットＭ１、Ｍ２及びハニカム体Ｍ３を用いて次のようにして製造されている。   Thus, the board material M is manufactured as follows using the two glass fiber mats M1 and M2 and the honeycomb body M3 formed as described above.

まず、両ガラス繊維マットＭ１、Ｍ２を切断により形成するためのロール状ガラス繊維マット材料（ガラス繊維マットＭ１、Ｍ２と同様の形成材料からなる）を準備する。そして、このように準備したロール状ガラス繊維マット材料をコンベアによりその上に順次水平状に引き出しながら、このように順次引き出されるロール状ガラス繊維マット材料の上に、一定量の発泡性熱硬化性樹脂を順次均一に散布する。   First, a roll-shaped glass fiber mat material (made of the same forming material as the glass fiber mats M1 and M2) for forming both the glass fiber mats M1 and M2 by cutting is prepared. Then, while the roll-shaped glass fiber mat material prepared in this way is sequentially pulled out horizontally on the conveyor, a certain amount of foamable thermosetting property is placed on the roll-shaped glass fiber mat material that is sequentially pulled out in this way. Spread the resin evenly in sequence.

然る後、このように発泡性熱硬化性樹脂を順次散布されるロール状ガラス繊維マット材料を、上記発泡性熱硬化性樹脂の溶融温度以上及び硬化開始温度以下の範囲の加熱温度にて加熱する。これにより、ロール状ガラス繊維マット材料上に順次散布された熱硬化性樹脂を、その溶融により、当該ガラス繊維マットに付着させる。   Thereafter, the roll-shaped glass fiber mat material to which the foamable thermosetting resin is sequentially sprayed in this way is heated at a heating temperature in the range of the melting temperature of the foamable thermosetting resin and the curing start temperature. To do. Thereby, the thermosetting resin sequentially sprinkled on the roll-shaped glass fiber mat material is adhered to the glass fiber mat by melting thereof.

ついで、このように熱硬化性樹脂をその溶融により付着させたガラス繊維マット材料を一対のローラにより挟持して加圧しながら送り出すことで、上記発泡性熱硬化性樹脂が冷却固化される。その後、このように熱硬化性樹脂を冷却固化したガラス繊維マット材料を両ガラス繊維マットＭ１、Ｍ２の各々に対応する各所定の長さに切断して当該両ガラス繊維マットＭ１、Ｍ２とする。   Next, the foamable thermosetting resin is cooled and solidified by sandwiching the glass fiber mat material to which the thermosetting resin has been adhered by melting in this way by sandwiching it with a pair of rollers and feeding it. Thereafter, the glass fiber mat material obtained by cooling and solidifying the thermosetting resin in this manner is cut into predetermined lengths corresponding to the glass fiber mats M1 and M2, respectively, to form the glass fiber mats M1 and M2.

然る後、上述したハニカム体Ｍ３を当該両ガラス繊維マットＭ１、Ｍ２の間に挟持するように積層する。このとき、両ガラス繊維マットＭ１、Ｍ２は、その各熱硬化性樹脂の付着面にて、ハニカム体Ｍ３の各面に対向するように、積層される。   Thereafter, the above-described honeycomb body M3 is laminated so as to be sandwiched between the two glass fiber mats M1 and M2. At this time, the two glass fiber mats M1 and M2 are laminated so as to face each surface of the honeycomb body M3 on the surface to which each thermosetting resin is attached.

そして、このように積層された積層体をプレス機により加圧及び加熱して成形する。この成形過程では、上述のように両ガラス繊維マットＭ１、Ｍ２に付着済みの発泡性熱硬化性樹脂が発泡し当該両ガラス繊維マットＭ１、Ｍ２の間及びハニカム体Ｍ３の各六角形状開孔部内に入り込みながら硬化する。このようにしてボード材料Ｍが製造されている。   And the laminated body laminated | stacked in this way is pressurized and heated with a press, and it shape | molds. In this molding process, as described above, the foamable thermosetting resin adhered to both the glass fiber mats M1 and M2 is foamed, and between the glass fiber mats M1 and M2 and in each hexagonal opening of the honeycomb body M3. It hardens while entering. In this way, the board material M is manufactured.

このように製造されたボード材料Ｍにおいては、両ガラス繊維マットＭ１、Ｍ２が、上述のごとく、軽量でその厚さ方向と直交する方向の応力に対して強いという特性を有するとともに、ハニカム体Ｍ３が、上述のごとく、軽量でその厚さ方向に作用する応力に対し強いという特性を有する。従って、このような両ガラス繊維マットＭ１、Ｍ２及びハニカム体Ｍ３の双方の特性が、相俟って、軽量で高い剛性を有するボード材料Ｍが提供され得る。   In the board material M manufactured in this way, both the glass fiber mats M1 and M2 are lightweight and strong against stress in the direction perpendicular to the thickness direction as described above, and the honeycomb body M3. However, as described above, it has the characteristics of being lightweight and strong against stress acting in the thickness direction. Accordingly, the properties of both the glass fiber mats M1 and M2 and the honeycomb body M3 can be combined to provide a board material M that is lightweight and has high rigidity.

なお、上述した発泡性熱硬化性樹脂のその発泡によるハニカム体Ｍ３の各開孔部内への入り込みは、ハニカム体Ｍ３の各開孔部内の空圧による抵抗のため、完全にはなされない。従って、ハニカム体Ｍ３の各開孔部内には空気部が残存する。その結果、ボード材料Ｍは高い吸音性及び断熱性を有する。   Note that the above-described foamable thermosetting resin does not completely enter into each aperture portion of the honeycomb body M3 due to the foaming because of resistance due to air pressure in each aperture portion of the honeycomb body M3. Therefore, an air part remains in each aperture of the honeycomb body M3. As a result, the board material M has high sound absorption and heat insulation.

以上のように製造されたボード材料Ｍは、前後両側ボード部材６０ａ、６０ｂの各々の外形形状に合わせて加工形成されることで、前後両側ボード部材６０ａ、６０ｂとして構成される。   The board material M manufactured as described above is processed and formed in accordance with the outer shape of each of the front and rear side board members 60a and 60b, thereby forming the front and rear side board members 60a and 60b.

It is adhered on the right front part on the back surface, and the right end parts of the front and rear side board members 60a, 60b are connected. Further, the right hinge band 60h is adhered to the right front part of the surface of the rear board member 60b on the back side of the rear skin member 60d by the rear end part 62a, and the front board member 60a by the front end part 61b. The right end portions of the front and rear side board members 60a and 60b are connected to each other on the right rear portion of the back surface of the front and rear sides.

また、両左側ヒンジ帯６０ｅ、６０ｆのうち左側ヒンジ帯６０ｅは、図２、図７或いは図８から分かるように、前後両側ボード部材６０ａ、６０ｂの各左端部間に連結されており、一方、左側ヒンジ帯６０ｆは、左側ヒンジ帯６０ｅの右側にて、当該左側ヒンジ帯６０ｅに並んで前後両側ボード部材６０ａ、６０ｂの各左端部間に連結されている。   Further, of the left hinge bands 60e and 60f, the left hinge band 60e is connected between the left end portions of the front and rear board members 60a and 60b, as can be seen from FIG. 2, FIG. 7, or FIG. The left hinge band 60f is connected between the left end portions of the front and rear board members 60a and 60b along the left hinge band 60e on the right side of the left hinge band 60e.

ここで、左側ヒンジ帯６０ｅは、前端部６３ａにより、前側表皮部材６０ｃの裏側にて前側ボード部材６０ａの表面の左側後部上に接着されるとともに、後端部６１ｂにより、後側ボード部材６０ｂの裏面の左側前部上に接着されて、前後両側ボード部材６０ａ、６０ｂの各左端部を連結している。また、左側ヒンジ帯６０ｆは、後端部６４ａにより、後側表皮部材６０ｄの裏側にて後側ボード部材６０ｂの表面の左側前部上に接着されるとともに、前端部６１ｂにて、前側ボード部材６０ａの裏面の左側後部上に接着されて、前後両側ボード部材６０ａ、６０ｂの各左端部を連結している。   Here, the left hinge band 60e is bonded to the left rear portion of the front board member 60a on the back side of the front skin member 60c by the front end portion 63a, and at the rear end portion 61b of the rear board member 60b. It is adhered on the left front part of the back surface and connects the left end parts of the front and rear side board members 60a, 60b. Further, the left hinge band 60f is adhered to the left front part of the surface of the rear board member 60b on the back side of the rear skin member 60d by the rear end part 64a, and at the front end part 61b, the front board member It adheres on the left rear part of the back surface of 60a, and connects the left end parts of both front and rear board members 60a, 60b.

本実施形態において、上記不織布としては、ボード６０の表面の外観を良好にするとともに前後両側ボード部材６０ａ、６０ｂをヒンジ連結するためのヒンジ機能を良好に発揮し得るように、十分な強度を有するニードルパンチ不織布、或いはこのニードルパンチ不織布にその裏面からラテックスを塗布した不織布が採用されている。なお、表皮部材のための不織布は、ヒンジ機能を有さない不織布であってもよい。   In the present embodiment, the non-woven fabric has sufficient strength so as to improve the appearance of the surface of the board 60 and to exhibit a hinge function for hinge-connecting the front and rear board members 60a and 60b. A needle punched nonwoven fabric or a nonwoven fabric obtained by applying latex to the needle punched nonwoven fabric from the back side is employed. The nonwoven fabric for the skin member may be a nonwoven fabric that does not have a hinge function.

以上のように構成した本実施形態において、折り畳み型ボード６０が、図１にて示すごとく、収納庫５０の収納庫本体５１の横断面Ｌ字状開口部５１ａ内に着脱可能に嵌装されていれば、当該ボード６０は、上述したごとく、その外周下部にて、収納庫本体５１の上記横断面Ｌ字状開口部５１ａの環状底面上に着座している。これにより、ボード６０は、当該自動車内の床４０の後部の床部材を兼用しつつ収納庫５０の蓋としての役割を果たす。   In the present embodiment configured as described above, the foldable board 60 is detachably fitted into the L-shaped opening 51a in the transverse section of the storage body 51 of the storage 50 as shown in FIG. Then, as described above, the board 60 is seated on the annular bottom surface of the L-shaped opening 51a in the transverse section of the storage body 51 at the lower peripheral portion thereof. Thereby, the board 60 serves as a lid for the storage 50 while also serving as a floor member at the rear of the floor 40 in the automobile.

このような状態において、収納庫５０内の収容物、例えば、スペアタイヤを取り出したり、或いは、他の物を収納庫５０内に収納するにあたっては、乗員が、当該自動車の車体の後部側にて、上記バックドアを開いて、ボード６０の後側ボード部材６０ｂの上記把持部を把持して上方に持ち上げる。ここで、上述したごとく、後側ボード部材６０ｂは、軽量なボード材料Ｍにより形成されているため、軽量である。従って、乗員は、後側ボード６０ｂを上述のごとく容易に持ち上げることができる。   In such a state, when taking out the stored items in the storage 50, for example, spare tires, or storing other items in the storage 50, the occupant is at the rear side of the vehicle body of the vehicle. Then, the back door is opened, the grip portion of the rear board member 60b of the board 60 is gripped and lifted upward. Here, as described above, since the rear board member 60b is formed of the lightweight board material M, it is lightweight. Accordingly, the passenger can easily lift the rear board 60b as described above.

これに伴い、後側ボード部材６０ｂは、前側ボード部材６０ａとの境界である折り畳み線Ｌを基準として、図１にて反時計方向へ回動して、図５にて示すごとく、前側表皮部材６０ｃの上方に半開き状態となり、さらに同一方向に回動されて、前側表皮部材６０ｃを介し前側ボード部材６０ａ上に折り畳まれる。このことは、ボード６０が、折り畳み線Ｌを基準に、表面側へ二つ折りに折り畳まれることを意味する。   Accordingly, the rear board member 60b rotates counterclockwise in FIG. 1 with reference to the fold line L that is a boundary with the front board member 60a, and as shown in FIG. It is in a half-open state above 60c, is further rotated in the same direction, and is folded on the front board member 60a via the front skin member 60c. This means that the board 60 is folded in half on the front side with respect to the fold line L.

一方、ボード６０をその裏面側から折り畳むにあたっては、前側ボード部材６０ａをその後側ボード部材６０ｂとの対向縁部にて上方へ持ち上げて傾斜状にした状態にて、後側ボード部材６０ｂを前側ボード部材に６０ｂに向けてその裏面側から回動させる（図６参照）。このことは、ボード６０が、折り畳み線Ｌを基準に、裏面側へ二つ折りに折り畳まれることを意味する。   On the other hand, when the board 60 is folded from the back side, the front board member 60a is lifted upward at the opposite edge to the rear board member 60b so that the rear board member 60b is inclined. The member is rotated from the back side toward 60b (see FIG. 6). This means that the board 60 is folded in half on the back side with respect to the fold line L.

このようなボード６０の折り畳み過程につき、両左側ヒンジ帯６０ｅ、６０ｆ及び両右側ヒンジ帯６０ｇ、６０ｈとの関係において説明すると、ボード６０が、図１にて示す状態にあるとき、両左側ヒンジ帯６０ｅ及び６０ｆは、図７（ｃ）及び図８（ｃ）にて示すごとく、クランク形状に折れ曲がった状態にあるとともに、両右側ヒンジ帯６０ｇ、６０ｈも、それぞれ、両左側ヒンジ帯６０ｅ、６０ｆとは逆のクランク形状に折れ曲がった状態にある。   The folding process of the board 60 will be described in relation to the left hinge bands 60e and 60f and the right hinge bands 60g and 60h. When the board 60 is in the state shown in FIG. As shown in FIGS. 7 (c) and 8 (c), 60e and 60f are in a state of being bent into a crank shape, and both right hinge bands 60g and 60h are both left and right hinge bands 60e and 60f, respectively. Is bent in the opposite crank shape.

即ち、左側ヒンジ帯６０ｅは、図７（ｃ）にて示すごとく、前端部６４ｂから中間部６４ｃを介し後端部６４ａにかけて階段状に上がるようなクランク形状となっており、一方、左側ヒンジ帯６０ｆは、図８（ｃ）にて示すごとく、前端部６３ａから中間部６３ｃを介し後端部６３ｂにかけて階段状に下がるようなクランク形状となっている。また、両右側ヒンジ帯６０ｇ、６０ｈのうち、右側ヒンジ帯６０ｇは、左側ヒンジ帯６０ｅと同様のクランク形状に折れ曲がった状態にあるとともに、右側ヒンジ帯６０ｈは、左側ヒンジ帯６０ｆと同様のクランク形状に折れ曲がった状態にある。   That is, as shown in FIG. 7C, the left hinge band 60e has a crank shape that rises in a stepped manner from the front end part 64b to the rear end part 64a through the intermediate part 64c. As shown in FIG. 8C, 60f has a crank shape that falls in a stepped manner from the front end portion 63a to the rear end portion 63b via the intermediate portion 63c. Of the right hinge bands 60g and 60h, the right hinge band 60g is bent into the same crank shape as the left hinge band 60e, and the right hinge band 60h is the same crank shape as the left hinge band 60f. It is in a state of being bent.

このような状態において、後側ボード部材６０ｂを上述のごとく持ち上げて反時計方向に回動させたとき、後側ボード部材６０ｂは、図７（ｂ）及び図８（ｂ）にて示すごとく、前側ボード部材６０ａに対し垂直に立ち上がった状態となり、然る後、図７（ａ）及び図８（ａ）にて示すごとく、前側ボード部材６０ａ上に前後両側表皮部材６０ｃ、６０ｄを介し折り畳まれた状態になる。   In such a state, when the rear board member 60b is lifted and rotated counterclockwise as described above, the rear board member 60b is as shown in FIGS. 7B and 8B. As shown in FIGS. 7 (a) and 8 (a), it is folded up on the front board member 60a via both front and rear skin members 60c and 60d. It becomes a state.

ここで、後側ボード部材６０ｂが上述のごとく前側ボード部材６０ａに対し垂直に立ち上がった状態になったとき、左側ヒンジ帯６０ｅが、図７（ｂ）にて示すごとく、中間部６４ｃ及び後端部６４ａを前端部６４ｂに対し垂直にかつ直線状に立ち上げるようなＬ字形状になる。一方、左側ヒンジ帯６０ｆは、図８（ｂ）にて示すごとく、直線状に位置する前端部６２ａ及び中間部６３ｂに対し後端部６３ｂを垂直に立ち上げるようなＬ字形状になる。また、両右側ヒンジ帯６０ｇ、６０ｈのうち、右側ヒンジ帯６０ｇは、左側ヒンジ帯６０ｅと同様のＬ字形状になるとともに、右側ヒンジ帯６０ｂｈは、左側ヒンジ帯６０ｆと同様のＬ字形状になる。   Here, when the rear board member 60b rises perpendicularly to the front board member 60a as described above, the left hinge band 60e has the intermediate portion 64c and the rear end as shown in FIG. 7B. The portion 64a is L-shaped so as to rise vertically and linearly with respect to the front end portion 64b. On the other hand, as shown in FIG. 8B, the left hinge band 60f is L-shaped so that the rear end portion 63b rises perpendicularly to the front end portion 62a and the intermediate portion 63b that are positioned linearly. Of the right hinge bands 60g and 60h, the right hinge band 60g has an L shape similar to that of the left hinge band 60e, and the right hinge band 60bh has an L shape similar to that of the left hinge band 60f. .

さらに、上述のように後側ボード部材６０ｂが前側ボード部材６０ａ上に折り畳まれた状態になったとき、両左側ヒンジ帯６０ｅ、６０ｆは、図７（ａ）及び図８（ａ）にて示すごとく、ともに、コ字形状となる。このとき、両右側ヒンジ帯６０ｇ、６０ｈも同様に、ともに、コ字形状となる。   Furthermore, when the rear board member 60b is folded on the front board member 60a as described above, the left hinge bands 60e and 60f are shown in FIGS. 7A and 8A. As such, both are U-shaped. At this time, both the right hinge bands 60g and 60h are similarly U-shaped.

このようにして、ボード６０は、後側ボード部材６０ｂ及び後側表皮部材６０ｃでもって、収納庫５０の開口部の後側半分部分を開く。その結果、収納庫５０内のスペアタイヤを取り出したり、或いは、他の物を収納庫５０内に収納することができる。   In this way, the board 60 opens the rear half of the opening of the storage 50 with the rear board member 60b and the rear skin member 60c. As a result, the spare tire in the storage 50 can be taken out, or other items can be stored in the storage 50.

然る後、乗員が、後側ボード部材６０ｂの上記把持部を把持して上方に持ち上げることにより、後側ボード部材６０ｂを、折り畳み線Ｌを基準として、各ヒンジ帯６０ｅ〜６０ｈを介し、収納庫５０の開口部の後側半分部分を閉塞するように回動する。これにより、ボード部材６０は、再び、当該自動車内の床４０の後部の床部材を兼用しつつ収納庫５０の蓋としての役割を果たす。   Thereafter, the occupant grasps the grip portion of the rear board member 60b and lifts it upward, so that the rear board member 60b is stored via the hinge bands 60e to 60h with the fold line L as a reference. It rotates so that the rear half part of the opening part of the store | warehouse | chamber 50 may be obstruct | occluded. Thereby, the board member 60 plays the role of a lid for the storage 50 while also serving as a floor member at the rear of the floor 40 in the automobile.

ここで、上述のように前後両側ボード部材６０ａ、６０ｂに連結された各ヒンジ帯６０ｅ〜６０ｈによれば、両ヒンジ帯６０ｅ、６０ｇは、折り畳み線Ｌに沿う方向からみて、両ヒンジ帯６０ｆ、６０ｈに対し前後両側ボード部材６０ａ、６０ｂ間にて互いに交差するように連結されていることとなる。   Here, according to the hinge bands 60e to 60h connected to the front and rear side board members 60a and 60b as described above, both the hinge bands 60e and 60g are seen from the direction along the fold line L. With respect to 60h, it will be connected so that it may mutually cross | intersect between board member 60a, 60b on both sides.

このため、上述のように、ボード６０をその表面側から折り畳む際に、後側ボード部材６０ｂを前側ボード部材６０ａに向けてその表面側から回動させるとき、後側ボード部材６０ｂは、両ボード部材６０ａ、６０ｂの各表面の対向表面部位を中心として前側ボード部材６０ａに向けてその表面側から回動する。従って、後側ボード部材６０ｂは、その表面にて、前側ボード部材６０ａの表面に重なるように１８０°回動する。一方、後側ボード部材６０ｂを前側ボード部材６０ｂに向けてその裏面側から回動させるとき、前側ボード部材６０ａを後側ボード部材６０ｂとの対向縁部側から上方へ傾斜状に持ち上げた状態にて、後側ボード部材６０ｂを、前後両側ボード部材６０ａ、６０ｂの各裏面の対向裏面部位を中心として前側ボード部材６０ａに向けてその裏面側から回動させる。従って、後側ボード部材６０ｂは、その裏面にて、前側ボード部材６０ａの裏面に重なるように１８０°回動する。   Therefore, as described above, when the board 60 is folded from the front side, when the rear board member 60b is rotated from the front side toward the front board member 60a, the rear board member 60b It rotates from the surface side toward the front board member 60a centering on the opposing surface site | part of each surface of member 60a, 60b. Accordingly, the rear board member 60b is rotated 180 ° on its surface so as to overlap the surface of the front board member 60a. On the other hand, when the rear board member 60b is rotated from the back side toward the front board member 60b, the front board member 60a is lifted upward from the opposite edge side to the rear board member 60b. Then, the rear board member 60b is rotated from the back surface side toward the front board member 60a around the opposite back surface portions of the back surfaces of the front and rear board members 60a and 60b. Therefore, the rear board member 60b is rotated 180 ° on the back surface so as to overlap the back surface of the front board member 60a.

このことは、ボード６０は、その表面側或いは裏面側への折り畳みにあたり、後側ボード部材６０ｂを３６０°という広い角度範囲以内にて回動させ得ることを意味する。その結果、収納庫５０内の収容物を取り出したり、或いは、他の物を収納庫５０内に収納するにあたり、ボード６０を表面側及び裏面側のいずれに向けて折り畳んでも、収納庫５０の開口部の開口部分を十分に開くことができて、便利である。   This means that the board 60 can be rotated within a wide angle range of 360 ° when the board 60 is folded to the front side or the back side. As a result, when taking out the contents in the storage 50 or storing other things in the storage 50, the board 60 can be opened regardless of whether the board 60 is folded toward the front side or the back side. It is convenient because the opening of the part can be sufficiently opened.

ここで、上述のごとく、各ヒンジ帯６０ｅ〜６０ｈは、ともに、上述した不織布でもって形成されているから、当該各ヒンジ帯６０ｅ〜６０ｈは、伸縮不能で柔軟性を有する。従って、ボード６０をその表面側或いは裏面側に向けて折り畳む際には、後側ボード部材６０ｂが、前後両側ボード部材６０ａ、６０ｂの各表面の対向表面部位或いは各裏面の対向裏面部位の間に間隙を形成することなく、当該各表面の対向表面部位或いは各裏面の対向裏面部位を基準に回動することができる。従って、ボード６０をその表面側或いは裏面側への折り畳みが円滑になされ得る。   Here, as described above, since each of the hinge bands 60e to 60h is formed of the above-described nonwoven fabric, each of the hinge bands 60e to 60h is not stretchable and has flexibility. Therefore, when the board 60 is folded toward the front surface side or the back surface side, the rear board member 60b is located between the front surface portions of the front and rear side board members 60a, 60b or the back surface portions of the back surfaces. Without forming a gap, it can be rotated with reference to the opposing surface portion of each surface or the opposing back surface portion of each back surface. Therefore, the board 60 can be smoothly folded to the front side or the back side.

また、左側ヒンジ帯６０ｅ、６０ｆは、前後両側ボード部材６０ａ、６０ｂの各対向縁部の右端部側に位置し、一方、右側ヒンジ帯６０ｇ、６０ｈは、前後両側ボード部材６０ａ、６０ｂの各対向縁部の左端部側に位置する。しかも、左側ヒンジ帯６０ｅ、６０ｆは、互いに近接して位置するとともに、右側ヒンジ帯６０ｇ、６０ｈも互いに近接して位置する。このため、左側ヒンジ帯６０ｅ、６０ｆの間隔及び右側ヒンジ帯６０ｇ、６０ｈの間隔は、共に、左側ヒンジ帯６０ｅ、６０ｆと右側ヒンジ帯６０ｇ、６０ｈとの間隔に比べて狭い。   The left hinge bands 60e and 60f are located on the right end side of the opposing edges of the front and rear side board members 60a and 60b, while the right hinge bands 60g and 60h are the opposite sides of the front and rear side board members 60a and 60b. Located on the left end side of the edge. Moreover, the left hinge bands 60e and 60f are positioned close to each other, and the right hinge bands 60g and 60h are also positioned close to each other. For this reason, the distance between the left hinge bands 60e, 60f and the distance between the right hinge bands 60g, 60h are both narrower than the distance between the left hinge bands 60e, 60f and the right hinge bands 60g, 60h.

このため、ボード６０のその表面側或いは裏面側への折り畳みにあたり、前後両側ボード部材６０ａ、６０ｂが、その各対向縁部の全体に亘り相互に均一に接合した状態に維持され得る。その結果、ボード６０のその表面側或いは裏面側への折り畳みが円滑になされ得る。   For this reason, when the board 60 is folded to the front surface side or the back surface side, the front and rear side board members 60a and 60b can be maintained in a state of being uniformly bonded to each other over the entire opposing edge portions. As a result, the board 60 can be smoothly folded to the front side or the back side.

また、各ヒンジ帯６０ｅ〜６０ｈを形成する不織布が、上述のごとく、十分な強度を有するニードルパンチ不織布、或いはこのニードルパンチ不織布にその裏面からラテックスを塗布した不織布でもって形成されているから、各ヒンジ帯６０ｅ〜６０ｈは、損傷等を招くことなく、長期に亘り良好にヒンジ機能を発揮し得る。また、表皮部材６０ｃ、６０ｄも不織布でもって形成されているから、外観を損ねることもない。   Moreover, since the nonwoven fabric which forms each hinge belt | band | zone 60e-60h is formed with the needle punch nonwoven fabric which has sufficient intensity | strength as mentioned above, or the nonwoven fabric which apply | coated latex from the back surface to this needle punch nonwoven fabric, The hinge bands 60e to 60h can exhibit a hinge function well over a long period of time without causing damage or the like. Further, since the skin members 60c and 60d are also formed of a nonwoven fabric, the appearance is not impaired.

また、ボード部材６０が、上述のように、収納庫５０の開口部を閉じて、床４０の後部の床部材を兼用しつつ収納庫５０の蓋としての役割を果たしている状態において、例えば、乗員がボード６０上に乗ったり、或いは荷物がボード６０上に置かれたりすると、乗員或いは荷物による荷重が、ボード６０に対しその上側から収納庫５０内に向けて作用することとなる。   Further, in the state where the board member 60 closes the opening of the storage 50 and serves as the lid of the storage 50 while serving as the floor member at the rear of the floor 40 as described above, for example, an occupant When the vehicle rides on the board 60 or the baggage is placed on the board 60, the load of the passenger or the baggage acts on the board 60 from the upper side toward the inside of the storage 50.

ここで、ボード６０は、収納庫５０の収納庫本体５１の横断面Ｌ字状開口部５１ａ内に着脱可能に嵌装されて、その外周下部にて、収納庫本体５１の上記横断面Ｌ字状開口部５１ａの環状底面上に着座している。また、当該ボード６０は、上述のごとく、前後両側ボード部材６０ａ、６０ｂの各対向縁部（折り畳み線Ｌに対応する）にて、中央突出部５４及び左右両側突出部５５ａ、５５ｂにより下方から受承されている。   Here, the board 60 is detachably fitted into the L-shaped opening 51a in the cross-section of the storage body 51 of the storage 50, and the L-shaped cross section of the storage body 51 at the lower outer periphery thereof. Is seated on the annular bottom surface of the opening 51a. Further, as described above, the board 60 is received from below by the central protrusion 54 and the left and right side protrusions 55a and 55b at the opposite edge portions (corresponding to the fold line L) of the front and rear side board members 60a and 60b. It is accepted.

このため、上述した荷重がボード６０に作用しても、ボード６０は、下方へ向けて湾曲することなく、原形状を良好に維持して、上記蓋としての役割を十分に果たすことができる。ここで、ボード６０は、上述のごとき高い剛性を有するボード材料Ｍでもって形成されている。従って、ボード６０は、より一層良好に原形状を維持し得る。   For this reason, even if the load mentioned above acts on the board 60, the board 60 can maintain the original shape satisfactorily without bending downward and can sufficiently fulfill the role as the lid. Here, the board 60 is formed of the board material M having high rigidity as described above. Therefore, the board 60 can maintain the original shape even better.
