Description

本発明は、自動車用デッキボードに関する。 The present invention also relates to Dekkibo de automotive.

ハッチバック形式の自動車では、リヤシートの背後からバックドアにいたるスペースが乗員の荷物を収容するデッキ部とされている。収納力や利便性を高めるため、デッキ部では、高さ方向の途中に平板状のデッキボードを配設して空間を上下に仕切ることが行われている。収納性を向上させるため、デッキ部に設けられる仕切りは、何らかの形で取り外しができる構造とされている。また、取り外した仕切りを車の外に保管するのは不便であり、デッキ部の壁沿いに起立配置するのはその分だけ荷物の収容スペースを犠牲にするため、デッキフロアに敷設されているデッキボードをデッキフロアから所定の高さに配設して高さ方向の仕切りとして兼用することが行われている。   In hatchback type cars, the space from the back of the rear seat to the back door is used as a deck for accommodating passengers' luggage. In order to enhance the storage capacity and convenience, in the deck section, a flat deck board is arranged in the middle of the height direction to partition the space up and down. In order to improve the storage property, the partition provided in the deck portion is structured to be removable in some form. In addition, it is inconvenient to store the removed partition outside the car, and standing up along the wall of the deck section sacrifices the luggage storage space, so the deck laid on the deck floor A board is disposed at a predetermined height from the deck floor and is also used as a partition in the height direction.

特許文献１の第２頁左欄第１４〜２１行および第２図には、概形がコ字状の支持バーをクオータトリムのポケットの外壁部から突出させた状態のもとで、トレイの両側部下縁に形成された半円形状の係合溝を支持バーの両側部に上方から係合させることにより、トレイを左右の支持バー上で係架することが記載されている。
特許文献２の段落００１４〜００１６には、リヤパッケージトレイを車両前方側の第１トレイと車両後方側の第２トレイとが車両前後方向に回動するようにヒンジ部により結合して構成し、第１トレイの車両前方側裏面に棒状支持体の車両前方側の短尺部と着脱可能に嵌合するファスナをインサートし、第２トレイの車幅方向両端の車両後方側裏面に棒状支持体の車両後方側の短尺部と着脱可能に嵌合する第２嵌合凹所を形成していることが記載されている。公報図７に示すように、第２嵌合凹所は棒状支持体の短尺部の径よりも広い溝とされている。
特公平５−１８７４２号公報 特開２００３−２４６２４１号公報 特開２００１−３１５６７２号公報 特開平１１−１２９３２２号公報 特開２００３−１２７７７９号公報 In the second column, left column, lines 14 to 21 and FIG. 2 of Patent Document 1, the support bar having a substantially U-shape is projected from the outer wall portion of the pocket of the quarter trim. It is described that the tray is suspended on the left and right support bars by engaging semicircular engaging grooves formed on the lower edges of both sides with both sides of the support bar from above.
In paragraphs 0014 to 0016 of Patent Document 2, the rear package tray is configured by connecting the first tray on the vehicle front side and the second tray on the vehicle rear side by a hinge portion so as to rotate in the vehicle front-rear direction. Fasteners that are detachably fitted to the vehicle front side short portion of the rod-shaped support body are inserted on the vehicle front-side back surface of the first tray, and the rod-shaped support vehicle is mounted on the vehicle rear-side back surface at both ends in the vehicle width direction of the second tray. It is described that a second fitting recess that is detachably fitted to the rear short portion is formed. As shown in FIG. 7, the second fitting recess is a groove wider than the diameter of the short portion of the rod-like support.
Japanese Patent Publication No. 5-18742 JP 2003-246241 A JP 2001-315672 A JP 11-129322 A JP 2003-127779 A

デッキボードの着脱操作は、バックドアが開いた状態でバックドア方向の車外から行われる。利用者は、デッキ部の前方側までは手が届き難いので、デッキボードの後側端縁を掴んでデッキボードの裏面にある係合具をデッキ部の側壁に形成された支持具に係合させる操作を行うことになるが、目標とする支持具にデッキボードの係合具を合わせ難かった。デッキフロアの面積が大きくなるにつれて、デッキボードも重くなり、デッキフロアより高い係合位置にデッキボードを着脱させるのが簡単でなくなる傾向にある。そこで、デッキボードの着脱操作をより円滑にさせることが求められていた。   The deck board is attached and detached from outside the vehicle in the direction of the back door with the back door opened. The user cannot easily reach the front side of the deck, so the user can grab the rear edge of the deck board and engage the engagement tool on the back of the deck board with the support formed on the side wall of the deck. However, it was difficult to align the deck board engagement tool with the target support tool. As the area of the deck floor increases, the deck board becomes heavier, and it tends to be difficult to attach and detach the deck board to an engagement position higher than the deck floor. Therefore, there has been a demand for smoother deck board attachment / detachment operations.

特許文献１記載の技術では、トレイの両側部下縁に形成された係合溝が半円形状であるため、トレイを水平から傾けると支持バーから係合溝が脱落してしまう。従って、トレイを左右の支持バー上で係架するためには、大きなトレイを伸ばした状態に保ったうえ、トレイを水平に保ちながら左右の支持バーの両側部に半円形状の係合溝を上方から合わせる必要があり、トレイの係架を円滑に行うことができなかった。
特許文献２記載の技術では、第１嵌合凹所を形成した第１トレイと第２嵌合凹所を形成した第２トレイとをヒンジ部により結合してパッケージトレイを構成しているため、第１トレイの前側にある第１嵌合凹所を棒状支持体の車両前方側の短尺部に嵌め込む操作を円滑に行いにくかった。また、パッケージトレイを第１嵌合凹所から取り外すには第１嵌合凹所まで手を伸ばして棒状支持体の車両前方側の短尺部から取り外す必要があるし、パッケージトレイが大きい場合には雰囲気温度による伸縮の影響が出やすいためパッケージトレイが抜けにくくなる。 In the technique described in Patent Document 1, since the engaging groove formed on the lower edge of both sides of the tray is semicircular, the engaging groove is dropped from the support bar when the tray is tilted from the horizontal. Therefore, in order to suspend the tray on the left and right support bars, keep the large tray extended, and maintain semi-circular engagement grooves on both sides of the left and right support bars while keeping the tray horizontal. It was necessary to match from above, and the tray could not be hung smoothly.
In the technique described in Patent Document 2, the package tray is configured by connecting the first tray in which the first fitting recess is formed and the second tray in which the second fitting recess is formed by the hinge portion. It was difficult to smoothly perform the operation of fitting the first fitting recess on the front side of the first tray into the short portion of the rod-like support on the vehicle front side. Further, the path Kkejitorei to the removed from the first fitting recess must be removed from the short section of the vehicle front side of the rod-like support Reach to the first fitting recess, when the package tray is large package tray for easy to get the effect of the expansion and contraction caused by the ambient temperature is less likely to escape.

なお、特許文献３の段落００１２〜００１５には、収納ボックスの開口前縁に棒材のストライカを取り付け、デッキボードのボード裏面における前端の左右両端寄りの位置に板バネ部材を取り付け、板バネ取付け部と板バネ部材との間にストライカの先端部が押し込まれるとストライカの先端部は相対回転可能に保持されることが記載されている。特許文献３記載の技術は収納ボックス上に載置されるデッキボードについての技術であり、デッキ部の側壁に形成された支持具にデッキボードを係合させる技術ではないため、当該支持具への大きなデッキボードの着脱操作を円滑にさせる課題を解決することができない。なお、板バネ取付け部と板バネ部材との間にストライカの先端部を押し込んでデッキボードを収納ボックスに取り付ける際には、板バネ部材を撓ませる力を加える必要があるため、大きなデッキボードを収納ボックスに対して円滑に取り付けることができないし、取り外すときも同様のことが言える。さらに、板バネ部材が回転動作の中心となるため、デッキボードを繰り返し開閉したときの耐久性を向上させる必要がある。 In paragraphs 0012 to 0015 of Patent Document 3, a bar striker is attached to the opening front edge of the storage box, and leaf spring members are attached to positions near the left and right ends of the front end on the back of the deck board. It is described that the tip of the striker is held so as to be relatively rotatable when the tip of the striker is pushed between the portion and the leaf spring member. The technique described in Patent Document 3 is a technique for a deck board placed on a storage box, and is not a technique for engaging the deck board with a support tool formed on the side wall of the deck unit. The problem of smooth attachment / detachment of a large deck board cannot be solved. When attaching the deck board to the storage box by pushing the tip of the striker between the leaf spring mounting portion and the leaf spring member, it is necessary to apply a force to deflect the leaf spring member. It cannot be smoothly attached to the storage box, and the same can be said when it is removed. Furthermore, since the leaf spring member is the center of the rotation operation, it is necessary to improve durability when the deck board is repeatedly opened and closed.

特許文献４には、熱可塑性樹脂をブロー成形することにより表壁と裏壁との間に形成される中空部内に真っ直ぐなパイプが配設されるとともにパイプの周囲は少なくとも裏壁と一体に連なる包囲壁で包囲されており、裏壁のパイプの端部に対応する部位にはパイプの端面に対する遊び間隔を保持する凹部を形成して成る中空二重壁構造体が記載されている。特許文献４記載の技術は、段落０００５に記載されるように、ブロー成形後において中空二重壁構造体が冷却収縮する過程でパイプの長さが相対的に増大する分を裏壁の凹部において逃がすことにより成形後の冷却収縮による変形歪みを生じさせない中空二重壁構造体を得る技術である。従来、この中空二重壁構造体からデッキボードを形成する際には、デッキ部の側壁に形成された支持具に係合させる係合具を熱可塑性樹脂からなる包囲壁に取り付けていた。しかし、前記係合具を中空二重壁構造体の包囲壁に取り付けると、成形後の冷却収縮の影響を受けて係合具に位置ずれが生じ、デッキボード着脱操作を円滑に行うことができないことがある。
特許文献５の段落０００８および図１には、樹脂製のボードに複数の孔が直線上に設けられ、該孔の下方に略Ｕ字状の補強部材受け部が複数形成され、該複数の補強部材受け部とボードとで造る空間に補強部材が挿入されて組み付けられていることが記載されている。 In Patent Document 4, a straight pipe is disposed in a hollow portion formed between a front wall and a back wall by blow molding a thermoplastic resin, and the periphery of the pipe is continuous with at least the back wall. A hollow double-wall structure is described which is surrounded by an enclosing wall and has a recess that holds a play interval with respect to the end face of the pipe at a portion corresponding to the end of the pipe on the back wall. As described in Paragraph 0005, the technique described in Patent Document 4 is based on the fact that the length of the pipe relatively increases in the process of cooling shrinkage after blow molding in the recess of the back wall. This is a technique for obtaining a hollow double-walled structure that does not cause deformation distortion due to cooling shrinkage after molding by escaping. Conventionally, when a deck board is formed from this hollow double-wall structure, an engagement tool that engages with a support formed on the side wall of the deck portion is attached to the surrounding wall made of thermoplastic resin. However, when the engaging tool is attached to the surrounding wall of the hollow double wall structure, the engaging tool is displaced due to the effect of cooling shrinkage after molding, and the deck board cannot be attached and detached smoothly. Sometimes.
In Paragraph 0008 and FIG. 1 of Patent Document 5, a plurality of holes are provided in a straight line on a resin board, and a plurality of substantially U-shaped reinforcing member receiving portions are formed below the holes. It is described that a reinforcing member is inserted and assembled in a space formed by the member receiving portion and the board .

本発明は、デッキボードの着脱操作をより円滑にさせることを目的とする。 The present invention aims to attachment and detachment manipulation of the de Kkibodo more smoothly.

課題を解決するための手段およびその作用・効果Means for solving the problems and their actions and effects

上記目的を達成するため、本発明は、自動車のシートの後方に形成される荷室の両側壁において比較的前側で車幅方向内側へ立設された一対の第一支持部と比較的後側で車幅方向内側へ立設された一対の第二支持部とに対して着脱可能に取り付けられる自動車用デッキボードであって、取付時に前記荷室を上下に仕切るデッキボード本体と、このデッキボード本体に固定され、前記一対の第一支持部に対して挟み込むことにより着脱可能に係合するとともに係合時に前記一対の第一支持部の双方を通る車幅方向を回転軸として回転動作可能な一対の第一係合具と、当該一対の第一係合具よりも後側で前記デッキボード本体に取り付けられるとともに前記一対の第二支持部に対して上方から近接して着脱可能に係合する一対の第二係合具とを備え、前記荷室の両側壁には前記一対の第二支持部よりも後側で前記デッキボード本体の車幅方向両縁部を載置する一対の第三支持部が形成されるとともに、各第三支持部には上方に開口した係合穴が形成され、前記デッキボード本体の下面には、後縁部で上方へ凹んだ一対の凹部が形成され、本自動車用デッキボードは、前記一対の凹部に取り付けられるとともに前記一対の第三支持部の係合穴に対して上方から近接して着脱可能に係合する一対の第三係合具をさらに備え、当該各第三係合具は、本自動車用デッキボードの取付時の位置を基準として、前記第三支持部に対して当該第三支持部の係合穴に上方から挿入して弾性変形の後に着脱可能に係合する可動部材と、前記凹部に固定されて前記可動部材を所定範囲で前後方向へ位置を変更可能に保持する保持部材とを有することを特徴とする。 In order to achieve the above object, the present invention provides a pair of first support portions and a relatively rear side that are erected inward in the vehicle width direction on the relatively front sides of both side walls of a cargo compartment formed at the rear of a vehicle seat. A deck board for an automobile that is detachably attached to a pair of second support portions erected inward in the vehicle width direction, and the deck board body that divides the cargo compartment up and down when installed, and the deck board It is fixed to the main body and is detachably engaged by being sandwiched between the pair of first support parts, and can be rotated about a vehicle width direction passing through both of the pair of first support parts at the time of engagement. a pair of first engaging member, the pair of second support portion close wearing detachably engaged from above with attached to the deck board body at the rear side than the pair of first engaging Gogu A pair of second engaging tools The with the side walls of the luggage compartment the third supporting portions of the pair of mounting a vehicle widthwise edges of the deck board body at the rear side than the pair of second support portions are formed, each of the An engagement hole opened upward is formed in the three support portions, and a pair of recesses recessed upward at the rear edge portion is formed on the lower surface of the deck board body. A pair of third engagement tools that are attached to the recesses and that are detachably engaged with the engagement holes of the pair of third support parts from above are provided. A movable member that is inserted from above into the engagement hole of the third support portion with respect to the third support portion, and is detachably engaged after elastic deformation, with reference to the position at the time of mounting the deck board for automobile. The position of the movable member fixed in the recess is changed in the front-rear direction within a predetermined range. Characterized by a holding member for holding the capability.

デッキボードを第一・第二支持部に取り付けるとき、まず、デッキボード本体に固定された一対の第一係合具を、比較的前側で荷室の両側壁に立設された一対の第一支持部に対して挟み込むことにより着脱可能に係合させる。ここで、一対の第一係合部は第一支持部への係合時に一対の第一支持部の双方を通る車幅方向を回転軸として回転動作可能とされるので、一対の第一係合具を固定したデッキボード本体は、前記第一支持部の双方を通る車幅方向を回転軸として回転操作可能とされる。次に、一対の第一支持部に係合したデッキボードの後側を下げるようにデッキボードを回転操作し、一対の第一係合具よりも後側でデッキボード本体に取り付けられた一対の第二係合具を、比較的後側で荷室の両側壁に立設された一対の第二支持部に対して上方から近接させて着脱可能に係合させる。これにより、荷室に対してデッキボードを円滑に取り付けることができる。
一方、デッキボードを第一・第二支持部から取り外すとき、まず、デッキボードの後側を上げるようにデッキボードを回転操作し、一対の第二支持部から一対の第二係合具を引き抜かせる。次に、第一支持部に対して挟み込んだ方向とは反対の方向へデッキボードを引く操作を行い、一対の第一支持部から一対の第一係合具の係合を解除させる。これにより、荷室からデッキボードを円滑に取り外すことができる。
以上より、本発明によると、デッキボードの着脱操作をより円滑にさせることができる。 When attaching the deck board to the first and second support portions, first, the pair of first engaging tools fixed to the deck board main body is paired with the first pair of firstly erected on both side walls of the cargo compartment on the relatively front side. It is detachably engaged by being sandwiched with respect to the support portion. Here, since the pair of first engagement portions can be rotated about the vehicle width direction passing through both of the pair of first support portions as the rotation axis when engaged with the first support portion, The deck board main body to which the combination is fixed can be rotated with the vehicle width direction passing through both of the first support portions as a rotation axis. Next, the deck board is rotated so as to lower the rear side of the deck board engaged with the pair of first support portions, and the pair of deck boards attached to the deck board main body on the rear side of the pair of first engaging tools. a second engaging member, so close to wear detachably engaged from above with respect to the second support portions of the pair erected on both side walls of the luggage compartment in a relatively rear side. Thereby, a deck board can be smoothly attached with respect to a luggage compartment .
On the other hand, when removing the deck board from the first and second support parts, first, the deck board is rotated so that the rear side of the deck board is raised, and the pair of second engagement tools are pulled from the pair of second support parts. Make it clear. Next, an operation of pulling the deck board in a direction opposite to the direction sandwiched with respect to the first support portion is performed to release the engagement of the pair of first engagement tools from the pair of first support portions. Thereby, a deck board can be smoothly removed from a luggage compartment.
As described above, according to the present invention, Ru can be a removable operation of the deck board more smoothly.

本発明を適用可能なシートは、リヤシートやサードシート等が考えられるが、後方に別のシートがあっても直後に荷室が形成されるシートでもよい。
上記第一支持部と上記第二支持部とは、一体化された部材で形成されてもよいし、別部材で形成されてもよい。
上記第一係合具には、本第一係合具だけで第一支持部を挟み込む係合具、デッキボード本体との間で第一支持部を挟み込む係合具、の両方が含まれる。 A seat to which the present invention can be applied may be a rear seat, a third seat, or the like, but it may be a seat in which a luggage compartment is formed immediately after another seat is present behind the seat.
The first support part and the second support part may be formed of an integrated member, or may be formed of separate members.
The first engagement tool includes both an engagement tool that sandwiches the first support part only with the first engagement tool and an engagement tool that sandwiches the first support part with the deck board main body.

前記デッキボード本体の下面に車幅方向両縁部で上方へ凹んだ別の凹部をそれぞれ形成し、前記各第一係合具および前記各第二係合具を前記デッキボード本体の下面から下方へ突出しないように前記各別の凹部に取り付けてもよい。係合具がデッキボード本体下面から突出していないので、デッキフロア上にデッキボードを載置したときに荷室の空間を広くさせることが可能になる。また、デッキボードの裏面を上側にしてデッキフロア上等、荷室内に配置してもデッキボード上が荷物置き場として好適となるので、デッキボードを表、裏リバーシブルにして使用することができ、利便性を向上させることができる。
ここで、デッキボード本体下面と第一・第二係合具下面とが面一にされていると、さらに好適である。 Formed on the lower surface of the deck board main body is another concave portion that is recessed upward at both edges in the vehicle width direction, and the first engaging tools and the second engaging tools are moved downward from the lower surface of the deck board main body. You may attach to each said another recessed part so that it may not protrude. Since the engagement tool does not protrude from the bottom surface of the deck board main body, it is possible to widen the space of the luggage compartment when the deck board is placed on the deck floor. Even if the deck board is placed on the deck floor, such as on the deck floor with the back side up, the deck board is suitable as a luggage storage area, so the deck board can be used with the front and back reversible. Can be improved.
Here, it is more preferable that the lower surface of the deck board main body and the lower surfaces of the first and second engaging tools are flush with each other.

前記第一係合具は、前記別の凹部に取り付けられたときに本自動車用デッキボードの取付時の位置を基準として、前記別の凹部との間で前側に開口を形成して前記第一支持部を当該開口から後方へ向かって挿入させて弾性変形することなく前記別の凹部とで挟み込むことにより当該第一支持部に対して着脱可能かつ回転動作可能に係合するようにしてもよい。すると、デッキボードを前方から斜め下の方向へスライドさせて第一支持部に対して回転動作可能に係合させ、当該デッキボードの後側を下方へ回転させて第二支持部に対して係合させるだけという簡単な操作でデッキボードを支持部に取り付けることができるので、デッキボードの着脱操作をさらに円滑にさせることが可能になる。また、第一係合具が弾性変形することなくデッキボード本体とで第一支持部を挟み込むので、デッキボードを第一支持部に係合させる際に加える力が少なくて済む。さらに、第一係合具が前方に開口を形成するので、デッキボード本体に寸法ばらつきが生じても第一支持部と係合する位置によって寸法ばらつきが吸収される。 Said first engagement Gogu, based on the position at the time of installation of the deck board the motor vehicle when attached to the another recess, the first to form an opening on the front side between the further recess The support portion may be inserted rearward from the opening and sandwiched between the other recesses without elastic deformation, so that the support portion can be detachably and rotationally engaged with the first support portion. . Then, the deck board is slid obliquely downward from the front to engage with the first support part so as to be rotatable, and the rear side of the deck board is rotated downward to engage with the second support part. Since the deck board can be attached to the support portion by a simple operation of only combining them, it is possible to make the deck board attachment / detachment operation smoother. Further, since the first support part is sandwiched between the deck board body and the first engagement tool without elastic deformation, less force is applied when the deck board is engaged with the first support part. Furthermore, since the first engagement tool forms an opening in the front, even if the deck board body has a dimensional variation, the dimensional variation is absorbed depending on the position of engagement with the first support portion.

前記第一係合具に、下面が前側となるほど下側となる傾斜面とされた基部と、下面が前記傾斜面に合わせられて前記基部から前方へ延出して前記別の凹部との間で前側に前記開口を形成する前方延出部とを形成してもよい。第一係合具の傾斜面を第二支持部の上に載せて前方へ滑らせていくと、自然に第一支持部が前記開口に入るので、デッキボードを荷室に取り付ける操作が容易になる。 Between the first engaging tool, a base portion that is inclined downward as the lower surface becomes the front side, and a lower surface that is aligned with the inclined surface and extends forward from the base portion to the another recess. You may form the front extension part which forms the said opening in the front side. When the inclined surface of the first engagement tool is placed on the second support portion and slid forward, the first support portion naturally enters the opening, so that the operation of attaching the deck board to the cargo compartment is easy. Become.

前記各第二係合具は、下側に開口を形成して前記第二支持部を当該開口から上方に向かって挿入させて弾性変形の後に挟持する一対の弾性部を有してもよい。すると、各第二支持部に対して一対の弾性部を上から嵌め込むという簡単な操作でデッキボードを支持部に取り付けることが可能になる。   Each of the second engagement tools may include a pair of elastic portions that form an opening on the lower side and insert the second support portion upward from the opening to be clamped after elastic deformation. Then, it becomes possible to attach the deck board to the support portion by a simple operation of fitting the pair of elastic portions from above with respect to each second support portion.

前記荷室の両側壁には前記一対の第二支持部よりも後側で前記デッキボード本体の車幅方向両縁部を載置する一対の第三支持部が形成されるとともに、各第三支持部には上方に開口した係合穴が形成され、前記デッキボード本体の下面には、後縁部で上方へ凹んだ一対の凹部が形成され、前記一対の凹部に取り付けられるとともに前記一対の第三支持部の係合穴に対して上方から近接して着脱可能に係合する一対の第三係合具をさらに備えている。当該各第三係合具は、前記第三支持部に対して当該第三支持部の係合穴に上方から挿入して弾性変形の後に着脱可能に係合する可動部材と、前記凹部に固定されて前記可動部材を所定範囲で前後方向へ位置を変更可能に保持する保持部材とを有する。
前後方向に三種類の係合具がデッキボード本体に取り付けられているので、バックドア方向の車外から荷室の高い位置に載せ置きする際、デッキボードが重かったりデッキボードの前縁部まで手が届かなかったりしても各係合具を順に係合させることができ、取付操作の負担が軽減される。また、デッキボード本体の前後方向に寸法誤差が生じても、デッキボードを確実に各支持部に取り付けることができる。 A pair of third support portions for mounting both edges in the vehicle width direction of the deck board body on the rear side of the pair of second support portions are formed on both side walls of the cargo compartment. An engagement hole opened upward is formed in the support portion, and a pair of recesses recessed upward at the rear edge portion is formed on the lower surface of the deck board body, and the pair of recesses are attached to the pair of recesses and the pair of recesses further comprising a pair of third engagement Gogu that detachably engage close from above the engagement hole of the third support section. Each said 3rd engaging tool is fixed to the said recessed part with the movable member which inserts into the engagement hole of the said 3rd support part from the upper direction with respect to the said 3rd support part, and is detachably engaged after elastic deformation. has been to have a holding member for holding and changing the position in the front-rear direction said movable member in a predetermined range.
Since three types of engagement tools are attached to the deck board body in the front-rear direction, when placing on the high position of the luggage compartment from the outside of the vehicle in the back door direction, the deck board is heavy or the hand up to the front edge of the deck board Even if it does not reach, each engagement tool can be engaged in order, and the burden of the mounting operation is reduced. Moreover, even if a dimensional error occurs in the front-rear direction of the deck board body, the deck board can be securely attached to each support portion.

前記保持部材は、前記凹部に取り付けられたときに、本自動車用デッキボードの取付時の位置を基準として、前記凹部との間で隙間を形成するとともに車幅方向よりも前後方向の方が長くされた貫通穴を有してもよい。前記可動部材は、前記貫通穴の車幅方向の長さよりも大きくされて前記凹部と前記保持部材との間で前後方向へスライド可能に設けられる頭部と、当該頭部から下方へ延出して前記貫通穴を貫通するとともに前記係合穴に上方から挿入して弾性変形の後に前記第三支持部に係合する係合片とを有してもよい。
可動部材の係合片を貫通穴に貫通させて保持部材を凹部に取り付けると可動部材の頭部が凹部と保持部材との間に挟まれるので、可動部材の抜け防止構造を別途設ける必要が無くなる。 The holding member, when mounted in the recess, with reference to the position at the time of installation of the deck board the motor vehicle, longer towards the front and rear direction than the vehicle width direction to form a gap between said recess You may have the made through hole. The movable member has a head that is larger than the length of the through hole in the vehicle width direction and is slidable in the front-rear direction between the recess and the holding member, and extends downward from the head. You may have the engagement piece which penetrates the said through-hole and is inserted in the said engagement hole from upper direction, and engages with the said 3rd support part after elastic deformation.
When the engaging piece of the movable member is passed through the through hole and the holding member is attached to the concave portion , the head of the movable member is sandwiched between the concave portion and the holding member, so that it is not necessary to separately provide a structure for preventing the movable member from coming off. .

前記デッキボード本体は、少なくとも樹脂を有する素材を成形して中空部を有する二重壁構造に形成された二重壁成形体と、この二重壁成形体の成形後の収縮に関わらない材質からなるとともに長手方向を車幅方向に向けて前記二重壁成形体の中空部内に挿通されて前記二重壁成形体に対して前記車幅方向にのみスライド可能に支持された補強材とを有してもよい。前記補強材は、両端部が二重壁成形体から露出するとともに当該両端部に前記各第一係合具が取り付けられてもよい。
補強材が中空部内に挿通されているので、デッキボードの裏面を略平面にすることができ、デッキボードを荷室のフロアに載置する際にデッキボードの裏面を上側にして載置してもデッキボード上が荷物の収納場所として好適となる。また、成形後に二重壁成形体が収縮しても当該収縮に関わらない材質からなる補強材の両端部に取り付けられている各第一係合具には位置ずれが生じないので、二重壁成形体の寸法誤差によるデッキボード着脱操作の円滑性の低下を防ぐことができる。
上記成形は、様々な成形が考えられるが、中空部を形成する観点からはブロー成形が好適である。この場合、上記樹脂は、合成樹脂が好適であり、熱可塑性樹脂がさらに好適である。
上記補強材は、収縮に関わらない材質からなり、中空二重壁成形体の一方の周囲壁から対向する他方の周囲壁にわたって一連に配置される。また、その形状は丸筒、角筒、Ｈ鋼型等の棒状部材など様々な補強材が考えられるが、強度と軽量化および各係合具の取付け性の観点からは係合具側に平坦面を有する角筒状の金属製パイプが好適であり、挿通性の観点からは真っ直ぐなパイプが好適である。またここで、収縮に関わらない材質とは中空二重壁成形体が成形後に収縮するのに対して中空部内に挿通された補強材が相対的に収縮を起こさないものであることを意味し、中空二重壁成形体の収縮に伴った変形が生じなければよく、補強材の成形後の経時的または外部環境による収縮が比較的小さいものも含まれる。
なお、上記補強材は、一箇所が二重壁成形体に固定されても当該補強材における二重壁成形体に固定されていない部分では二重壁成形体に対して長手方向にのみスライド可能とされるので、二重壁成形体に対して車幅方向にのみスライド可能に支持されていることになる。 The deck board body is formed of a double wall molded body formed into a double wall structure having a hollow portion by molding a material having at least a resin, and a material not related to shrinkage after molding of the double wall molded body. And a reinforcing member that is inserted into the hollow portion of the double wall molded body with its longitudinal direction facing the vehicle width direction and supported so as to be slidable only in the vehicle width direction with respect to the double wall molded body. May be. Both ends of the reinforcing material may be exposed from the double wall molded body, and the first engaging tools may be attached to the both ends.
Since the reinforcing material is inserted into the hollow part, the back of the deck board can be made substantially flat, and when the deck board is placed on the floor of the cargo compartment, the deck board is placed with the back side up. The deck board is also suitable as a luggage storage place. In addition, even if the double wall molded body shrinks after molding, there is no displacement in each first engagement tool attached to both ends of the reinforcing material made of a material not related to the shrinkage. It is possible to prevent the smoothness of the deck board attaching / detaching operation from being reduced due to the dimensional error of the molded body.
Although various shaping | molding can be considered for the said shaping | molding, blow molding is suitable from a viewpoint of forming a hollow part. In this case, the resin is preferably a synthetic resin, and more preferably a thermoplastic resin.
The reinforcing material is made of a material that is not related to shrinkage, and is arranged in a series from one peripheral wall of the hollow double-walled molded body to the other peripheral wall facing it. In addition, various reinforcing materials such as a round tube, a square tube, and a rod-shaped member such as an H steel mold can be considered, but from the viewpoint of strength and weight reduction and attachment of each engagement tool, it is flat on the engagement tool side. A rectangular pipe-shaped metal pipe having a surface is preferable, and a straight pipe is preferable from the viewpoint of insertion. Here, the material not related to shrinkage means that the reinforcing material inserted into the hollow portion does not shrink relatively while the hollow double wall molded body shrinks after molding. It is sufficient that the hollow double wall molded body is not deformed due to the shrinkage, and includes those in which the shrinkage due to the passage of time or after the reinforcement of the reinforcing material is relatively small.
The reinforcing material can be slid only in the longitudinal direction with respect to the double wall molded body at a portion not fixed to the double wall molded body in the reinforcing material even if one portion is fixed to the double wall molded body. Therefore, it is supported to be slidable only in the vehicle width direction with respect to the double wall molded body.

An automotive deck board (resin hollow double wall structure) 10 has a deck board main body 20 that divides the cargo compartment SP1 up and down when attached, and connects the deck board main body 20 to a support member 82 and a third support portion 86. Engagement tools 30, 40, and 50. The deck board main body 20 is formed of a double wall molded body 22 formed by molding a material having a resin into a double wall structure having a hollow portion HO1, and a double wall molded body with the longitudinal direction directed in the vehicle width direction. Reinforcing members 28 and 29 inserted into the hollow portions HO1 and HO2. The deck board main body 20 has a hinge in which the front board 20a in which the reinforcing material 28 is inserted into the hollow portion HO1 and the rear board 20b in which the reinforcing material 29 is inserted into the hollow portion HO2 have the vehicle width direction as the central axis of the rotation operation. The shape is connected by the portion 20c, and the rear board 20b can be rotated and overlapped on the front board 20a so as to bend the hinge portion 20c. If the rear board 20b is folded back onto the front board 20a with the deck board 10 mounted in the luggage compartment SP1, the luggage below the deck board 10 can be taken out, which is convenient.

二重壁成形体２２は、樹脂を有する素材をブロー成形することにより、間隔をおいて対向する表壁２２ａおよび裏壁２２ｂと、当該表壁２２ａおよび当該裏壁２２ｂの周縁部を閉塞して中空部ＨＯ１，ＨＯ２を形成する周囲壁２２ｃとが形成され、中空部を有する二重壁構造に形成されている。二重壁成形体２２を成形するための素材には、少なくとも樹脂を有する素材を用いることができ、アクリロニトリルブタジエンスチレン樹脂（ＡＢＳ樹脂）、ポリプロピレン（ＰＰ）、等の熱可塑性樹脂（合成樹脂の一種）、各種熱硬化性樹脂（合成樹脂の一種）、これらの樹脂に充てん材を添加した素材、等を用いることができる。本実施形態の二重壁成形体２２は、熱可塑性樹脂をブロー成形して、表壁２２ａと裏壁２２ｂとを溶着させて薄肉化させたヒンジ部２０ｃを形成しながら、補強材２８を挿入する前の前側ボードと補強材２９を挿入する前の後側ボードとを一体的に形成している。樹脂を薄肉化させてヒンジ部を形成すると、前後ボード２０ａ，ｂを折り畳み動作させるための新たな部品を取り付ける必要が無くなるので、デッキボードの製造コストを削減することが可能となる。   The double wall molded body 22 closes the front wall 22a and the back wall 22b opposed to each other at an interval and the peripheral portions of the front wall 22a and the back wall 22b by blow molding a material having resin. The surrounding wall 22c which forms the hollow parts HO1 and HO2 is formed, and it is formed in the double wall structure which has a hollow part. A material having at least a resin can be used as a material for forming the double wall molded body 22, and a thermoplastic resin (a kind of synthetic resin) such as acrylonitrile butadiene styrene resin (ABS resin) or polypropylene (PP). ), Various thermosetting resins (a kind of synthetic resin), materials obtained by adding fillers to these resins, and the like. The double-wall molded body 22 of the present embodiment inserts the reinforcing material 28 while forming the hinge portion 20c in which the front wall 22a and the back wall 22b are welded and thinned by blow molding a thermoplastic resin. The front board before the insertion and the rear board before inserting the reinforcing member 29 are integrally formed. When the hinge is formed by thinning the resin, it is not necessary to attach new parts for folding the front and rear boards 20a and 20b, so that the manufacturing cost of the deck board can be reduced.

また、二重壁成形体２２には、表壁２２ａの内壁と裏壁２２ｂの内壁とを繋ぐインナーリブがブロー成形と同時に複数形成され、車幅方向に向けて複数列設けられている。インナーリブは、例えば特開平１０−２３５７２０号公報に記載された手法で形成することができる。二重壁成形体内にインナーリブを形成すると、デッキボードの耐圧縮荷重性能を高めることができる。また、前側ボードの中空部ＨＯ１内には補強材２８を前後で挟んで車幅方向にのみスライド可能に支持するインナーリブ２２ｄおよび突起２２ｅが形成され、後側ボードの中空部ＨＯ２内には補強材２９を前後で挟んで車幅方向にのみスライド可能に支持する突起２２ｆおよびインナーリブ２２ｇが形成されている。   The double wall molded body 22 is formed with a plurality of inner ribs connecting the inner wall of the front wall 22a and the inner wall of the back wall 22b simultaneously with the blow molding, and is provided in a plurality of rows in the vehicle width direction. The inner rib can be formed by a technique described in, for example, Japanese Patent Application Laid-Open No. 10-235720. When the inner rib is formed in the double wall molded body, the resistance to compressive load of the deck board can be enhanced. In addition, inner ribs 22d and protrusions 22e are formed in the hollow portion HO1 of the front board so as to be slidable only in the vehicle width direction with the reinforcing member 28 sandwiched between the front and rear sides. Protrusions 22f and inner ribs 22g that support the material 29 so as to be slidable only in the vehicle width direction are formed.

さらに、二重壁成形体２２の裏面（デッキボード本体の下面２０ｄ）には、前縁部２０ｅ側の車幅方向両縁部２０ｇ，２０ｇで上方へ凹んだ一対の凹部２４，２４が形成され、後縁部２０ｆ側の車幅方向両縁部２０ｇ，２０ｇで上方へ凹んだ一対の第二凹部２６，２６が形成されている。凹部２４，２４の後側には、第二係合具４０，４０をねじ止めするためのねじ止め用穴が形成されている。凹部２４，２４の車幅方向内側の面には、補強材２８の両端部２８ａ，２８ａを二重壁成形体２２から突き出させて露出させる開口２４ａ，２４ａが形成されている。また、第二凹部２６，２６の車幅方向内側の面には、補強材２９の両端部２９ａ，２９ａを二重壁成形体２２から突き出させて露出させる開口２６ａ，２６ａが形成されている。
なお、デッキボード本体には、上記二重壁成形体の代わりに、射出成形による樹脂成形体、プレス成形による樹脂成形体、木質ボード、ハニカムボード、等を用いてもよい。 Furthermore, a pair of recesses 24 and 24 are formed on the back surface of the double-wall molded body 22 (the lower surface 20d of the deck board body) and are recessed upward at both edges 20g and 20g in the vehicle width direction on the front edge 20e side. A pair of second recesses 26, 26 are formed that are recessed upward at both edges 20g, 20g in the vehicle width direction on the rear edge 20f side. On the rear side of the recesses 24, 24, screwing holes for screwing the second engagement tools 40, 40 are formed. Openings 24 a and 24 a are formed on the inner surfaces of the recesses 24 and 24 in the vehicle width direction so as to project both ends 28 a and 28 a of the reinforcing member 28 from the double wall molded body 22 and expose them. Further, openings 26 a and 26 a are formed on the inner surfaces in the vehicle width direction of the second recesses 26 and 26 so that both end portions 29 a and 29 a of the reinforcing material 29 protrude from the double wall molded body 22 and are exposed.
For the deck board body, a resin molded body by injection molding, a resin molded body by press molding, a wood board, a honeycomb board, or the like may be used instead of the double wall molded body.

補強材２８，２９は、デッキボード１０の強度を補強するものであり、例えば真っ直ぐな角筒状の金属製パイプとされ、二重壁成形体２２のブロー成形後に長手方向を車幅方向に向けて二重壁成形体の中空部ＨＯ１，ＨＯ２内に挿通されている。同補強材２８，２９は、インナーリブ２２ｄ，ｇおよび突起２２ｅ，ｆにより二重壁成形体２２に対して車幅方向にのみスライド可能に支持されている。補強材２８，２９は、二重壁成形体２２の成形後の収縮に関わらない材質で形成され、鋼製やアルミニウム製の角パイプや丸パイプ等とすることができる。角パイプの場合には上下方向の厚みが二重壁成形体の表壁２２ａの内面と裏壁２２ｂの内面との間隔より少し小さいパイプを補強材とし、丸パイプの場合には二重壁成形体の表壁２２ａの内面と裏壁２２ｂの内面との間隔より少し小さい径のパイプを補強材とすればよい。   The reinforcing members 28 and 29 reinforce the strength of the deck board 10. For example, the reinforcing members 28 and 29 are straight rectangular tube-shaped metal pipes, and the longitudinal direction is directed in the vehicle width direction after the double wall molded body 22 is blow-molded. Are inserted into the hollow portions HO1 and HO2 of the double wall molded body. The reinforcing members 28 and 29 are supported by the inner ribs 22d and g and the protrusions 22e and f so as to be slidable only in the vehicle width direction with respect to the double wall molded body 22. The reinforcing members 28 and 29 are formed of a material that is not related to shrinkage after the molding of the double-wall molded body 22, and may be a square pipe or a round pipe made of steel or aluminum. In the case of a square pipe, the reinforcing material is a pipe whose vertical thickness is slightly smaller than the distance between the inner surface of the front wall 22a and the inner surface of the back wall 22b of the double wall molded body. A pipe having a diameter slightly smaller than the distance between the inner surface of the body front wall 22a and the inner surface of the back wall 22b may be used as the reinforcing material.

補強材２８を前側ボード２０ａ内に配設する際には、凹部２４，２４の一方の開口２４ａから二重壁成形体２２内へ補強材の一端２８ａを挿入し、インナーリブ２２ｄおよび突起２２ｅに沿って補強材２８を反対側の開口２４ａまで貫通させて所定位置に配置させればよい。補強材の両端部２８ａ，２８ａは、第一係合具３０，３０をねじ止めするためのねじ止め用穴が形成されるとともに、二重壁成形体の両側縁部（２０ｇ，２０ｇ）よりも車幅方向内側とされ、各凹部２４，２４で露出するようになっている。また、補強材２８を後側ボード２０ｂ内に配設する際には、第二凹部２６，２６の一方の開口２６ａから二重壁成形体２２内へ補強材の一端２９ａを挿入し、インナーリブ２２ｇおよび突起２２ｆに沿って補強材２９を反対側の開口２６ａまで貫通させて所定位置に配置させればよい。補強材の両端部２９ａ，２９ａは、第三係合具５０，５０をねじ止めするためのねじ止め用穴が形成されるとともに、二重壁成形体の両側縁部（２０ｇ，２０ｇ）よりも車幅方向内側とされ、各第二凹部２６，２６で露出するようになっている。
ここで、表壁２２ａの内面と裏壁２２ｂの内面との間隔は、突起２２ｅ，ｆの部分で補強材２８，２９の高さよりも若干狭くしてあり、突起２２ｅ，ｆに対向するインナーリブ２２ｄ，ｇへ補強材２８，２９を押しつけて前後方向へは移動しないように固定している。補強材２８，２９は、普段は樹脂成形された二重壁成形体２２に対して位置ずれを起こさないが、成形体が熱等の影響で寸法変化をおこした場合には、これに打ち勝つ剛性を有しているので、相対的なずれ（フローティング）が起こる。これにより、補強材２８，２９の両端部間の長さは、変化しない。そして、補強材２８の両端部２８ａ，２８ａに一対の第一係合具３０，３０が取り付けられ、補強材２９の両端部に一対の第三係合具５０，５０が取り付けられるようになっている。
以上説明したように、補強材２８，２９が中空部ＨＯ１，ＨＯ２内に挿入されているので、デッキボードの裏面を略平面にすることができる。従って、デッキボードをデッキフロア９６に載置する際に表を上にするのみならず裏面を上側にして載置しても荷物の載置面が略平面となるため、デッキボードの表、裏がともに荷物の収納場所として好適となる。また、成形後に二重壁成形体が収縮しても当該収縮に関わらない材質からなる補強材の両端部に取り付けられている第一係合具３０，３０間や第三係合具５０，５０間には位置ずれが生じないので、二重壁成形体の寸法誤差によってデッキボード着脱操作の円滑性が低下することを防ぐことができる。 When the reinforcing material 28 is disposed in the front board 20a, one end 28a of the reinforcing material is inserted into the double wall molded body 22 from one opening 24a of the recesses 24, 24, and the inner rib 22d and the protrusion 22e are inserted. The reinforcing material 28 may be penetrated to the opening 24a on the opposite side and disposed at a predetermined position. Both ends 28a, 28a of the reinforcing material are formed with screw holes for screwing the first engaging tools 30, 30, and more than both side edges (20g, 20g) of the double wall molded body. The inner side in the vehicle width direction is exposed at each of the recesses 24 and 24. Further, when the reinforcing member 28 is disposed in the rear board 20b, one end 29a of the reinforcing member is inserted into the double wall molded body 22 from one opening 26a of the second recesses 26, 26, and the inner rib What is necessary is just to penetrate the reinforcement material 29 to the opening 26a of the other side along 22g and protrusion 22f, and to arrange | position to a predetermined position. Both ends 29a and 29a of the reinforcing material are formed with screw holes for screwing the third engagement tools 50 and 50, and more than both side edges (20g, 20g) of the double wall molded body. It is the inside in the vehicle width direction and is exposed at each of the second recesses 26 and 26.
Here, the distance between the inner surface of the front wall 22a and the inner surface of the back wall 22b is slightly narrower than the height of the reinforcing members 28 and 29 at the portions of the protrusions 22e and f, and the inner ribs facing the protrusions 22e and f. The reinforcing members 28 and 29 are pressed against 22d and g to be fixed so as not to move in the front-rear direction. The reinforcing members 28 and 29 do not normally shift in position with respect to the resin-molded double wall molded body 22, but when the molded body undergoes a dimensional change due to the influence of heat or the like, the rigidity to overcome this Therefore, relative displacement (floating) occurs. Thereby, the length between the both ends of the reinforcing materials 28 and 29 does not change. Then, the pair of first engaging tools 30, 30 are attached to both end portions 28 a, 28 a of the reinforcing material 28, and the pair of third engaging tools 50, 50 are attached to both end portions of the reinforcing material 29. Yes.
As described above, since the reinforcing members 28 and 29 are inserted into the hollow portions HO1 and HO2, the back surface of the deck board can be made substantially flat. Accordingly, when the deck board is placed on the deck floor 96, not only the front side but also the back side of the deck board 96 is placed on the front side. Both are suitable as luggage storage locations. Further, even if the double wall molded body contracts after molding, the first engaging tools 30 and 30 or the third engaging tools 50 and 50 are attached to both ends of the reinforcing material made of a material not related to the contraction. Since no displacement occurs between them, it is possible to prevent the smoothness of the deck board attaching / detaching operation from being reduced due to the dimensional error of the double wall molded body.

なお、補強材２８，２９における長手方向の両端部を除く中央側の１箇所だけを二重壁成形体２２に固定してもよい。この場合でも、補強材２８，２９における二重壁成形体２２に固定されていない部分では二重壁成形体２２に対して長手方向にのみスライド可能に支持されていることになり、二重壁成形体２２に固定されていない両端部２８ａ，２９ａでは二重壁成形体２２の寸法変化を逃して係合具間の位置ずれを生じさせず、デッキボード着脱操作の円滑性が低下することを防ぐことができる。
また、デッキボード本体２０の表面に不織布等の表皮材を貼り付けて意匠性を高めてもよい。ここで、特公平４−５３６９６号公報に記載されたように二重壁成形体のブロー成形と同時に表皮材を貼り付けてもよいし、二重壁成形体を形成した後に表皮材を接着してもよい。また、デッキボード本体の裏面には表皮材を貼り付けず代わりに水拭き可能となるよう皺を形成する加工を行うことにより表、裏で異なる意匠にして、デッキボードの表、裏を荷物の種類によって使い分けできるようにしてもよい。 In addition, you may fix only one place of the center side except the both ends of the longitudinal direction in the reinforcing materials 28 and 29 to the double wall molded object 22. FIG. Even in this case, the portions of the reinforcing members 28 and 29 that are not fixed to the double wall molded body 22 are supported so as to be slidable only in the longitudinal direction with respect to the double wall molded body 22. At both end portions 28a and 29a not fixed to the molded body 22, the dimensional change of the double-wall molded body 22 is not missed, and the displacement between the engaging tools does not occur, and the smoothness of the deck board attaching / detaching operation is lowered. Can be prevented.
Moreover, you may affix the skin material, such as a nonwoven fabric, on the surface of the deck board main body 20, and may improve the design property. Here, as described in JP-B-4-53696, the skin material may be attached simultaneously with the blow molding of the double wall molded body, or the skin material is bonded after forming the double wall molded body. May be. In addition, the surface of the deck board is not attached to the back of the deck board. It may be possible to use properly depending on the type.

一対の第一支持部（外部の構成体）８３，８３に取り付けられる一対の第一係合具（連結部材）３０，３０は、前側ボード２０ａの凹部２４，２４に取り付けられて固定され、第一支持部８３，８３に対して挟み込むことにより着脱可能に係合するとともに、係合時に第一支持部８３，８３の双方を通る車幅方向を仮想の回転軸ＡＸ１として回転動作可能とされている。第一係合具３０，３０は、例えば、熱可塑性樹脂等の合成樹脂を第一係合具の形状に成形することにより形成することができる。各第一係合具３０，３０は、デッキボード本体の下面２０ｄ（一般面）から下方へ突出しないよう、当該下面と略面一となるように各凹部２４，２４に取り付けられている。   A pair of first engagement tools (connection members) 30 and 30 attached to the pair of first support parts (external components) 83 and 83 are attached and fixed to the recesses 24 and 24 of the front board 20a. While being detachably engaged by being sandwiched with respect to the one support portion 83, 83, the vehicle width direction passing through both of the first support portions 83, 83 at the time of engagement can be rotated about a virtual rotation axis AX1. Yes. The first engagement tools 30 and 30 can be formed, for example, by molding a synthetic resin such as a thermoplastic resin into the shape of the first engagement tool. The first engagement tools 30 and 30 are attached to the recesses 24 and 24 so as to be substantially flush with the lower surface so as not to protrude downward from the lower surface 20d (general surface) of the deck board body.

図７に示すように、第一係合具３０は、補強材２８にねじ止めするためのねじ止め用穴３０ａを有する補強材連結部３２が形成されているとともに、下面が前側となるほど下側となる傾斜面３４ａとされた基部３４と、下面３６ａが前記傾斜面３４ａに合わせられて基部３４から前方へ延出してデッキボード本体の凹部２４との間で前側に開口ＡＰ１を形成する前方延出部３６とが形成されている。また、補強材連結部３２と基部３４との間には、コ字状支持部材の架橋部８５を受け入れるために前後方向に向けた溝３２ａが形成されている。第一係合具３０は、凹部２４に露出した補強材の端部２８ａに形成されたねじ止め用穴に補強材連結部３２のねじ止め用穴３０ａを合わせて補強材２８にねじ止めされて固定される。これにより、補強材に固定された第一係合具がデッキボードの回動操作の軸となるので強度が向上して回動操作を繰り返すときのデッキボードの耐久性を向上させ、左右の第一係合具３０，３０間の距離がずれにくいという利点が得られる。
図１０に示すように、第一係合具３０は、凹部２４に取り付けられたときに、前方延出部３６と凹部２４との間で前側に開口ＡＰ１を形成する。ここで、前方延出部３６と凹部２４との間隔は第一支持部８３の径よりも若干大きくしてあり、第一係合具３０は第一支持部８３を開口ＡＰ１から後方へ向かって挿入させて弾性変形することなく凹部２４とで挟み込む。そして、第一係合具３０は、凹部２４とで第一支持部８３に対して挟み込むことにより着脱可能に係合するとともに、係合時に一対の第一支持部８３，８３の双方を通る車幅方向を回転軸ＡＸ１として回転動作可能とされる。なお、前方延出部３６の上面には上方へ延出して凹部２４との間隔を狭めた延出部３６ｂが形成されており、第一係合具３０は回転動作時に第一支持部８３から容易には脱落しないようになっている。 As shown in FIG. 7, the first engagement tool 30 is formed such that a reinforcing material coupling portion 32 having a screwing hole 30 a for screwing to the reinforcing material 28 is formed, and the lower the lower surface is the front side. The base 34 formed as an inclined surface 34a and the lower surface 36a are aligned with the inclined surface 34a and extend forward from the base 34 to form an opening AP1 on the front side between the concave portion 24 of the deck board body. A protruding portion 36 is formed. Further, a groove 32a is formed between the reinforcing material connecting portion 32 and the base portion 34 in the front-rear direction so as to receive the bridge portion 85 of the U-shaped support member. The first engagement tool 30 is screwed to the reinforcing material 28 by aligning the screwing hole 30a of the reinforcing material connecting portion 32 with the screwing hole formed in the end portion 28a of the reinforcing material exposed to the recess 24. Fixed. As a result, the first engagement tool fixed to the reinforcing material serves as the axis for the pivoting operation of the deck board, so that the strength is improved and the durability of the deck board when the pivoting operation is repeated is improved. The advantage that the distance between the one engagement tool 30 and 30 is hard to shift | deviate is acquired.
As shown in FIG. 10, when the first engagement tool 30 is attached to the recess 24, an opening AP <b> 1 is formed on the front side between the front extension 36 and the recess 24. Here, the distance between the front extension 36 and the recess 24 is slightly larger than the diameter of the first support 83, and the first engagement tool 30 moves the first support 83 from the opening AP1 to the rear. It is inserted and inserted into the recess 24 without elastic deformation. The first engagement tool 30 is detachably engaged by being sandwiched between the first support portion 83 and the recess 24, and the vehicle passes through both the pair of first support portions 83 and 83 when engaged. The width direction can be rotated about the rotation axis AX1. An extension portion 36b extending upward and narrowing the gap with the recess 24 is formed on the upper surface of the front extension portion 36, and the first engagement tool 30 is separated from the first support portion 83 during the rotation operation. It does not fall off easily.

一対の第二支持部８４，８４に取り付けられる一対の第二係合具４０，４０は、一対の第一係合具３０，３０よりも後側で前側ボード２０ａの凹部２４，２４に取り付けられて固定され、一対の第二支持部８４，８４に対して上方から近接して弾性変形の後に着脱可能に係合する。第二係合具４０，４０は、例えば、熱可塑性樹脂等の弾性を示す合成樹脂を第二係合具の形状に成形することにより形成することができる。各第二係合具４０，４０は、デッキボード本体の下面２０ｄから下方へ突出しないよう、当該下面と略面一となるように各凹部２４，２４に取り付けられている。   The pair of second engagement tools 40, 40 attached to the pair of second support portions 84, 84 are attached to the recesses 24, 24 of the front board 20 a on the rear side of the pair of first engagement tools 30, 30. And are detachably engaged with each other after elastic deformation by approaching the pair of second support portions 84, 84 from above. The second engagement tools 40, 40 can be formed, for example, by molding a synthetic resin exhibiting elasticity such as a thermoplastic resin into the shape of the second engagement tool. The second engaging tools 40, 40 are attached to the recesses 24, 24 so as to be substantially flush with the lower surface so as not to protrude downward from the lower surface 20d of the deck board body.

図８に示すように、第二係合具４０は、デッキボード本体の凹部２４にねじ止めするためのねじ止め用穴４０ａを有する本体部４２が形成されているとともに、凹部２４に取り付けられたときに下側に開口ＡＰ２を形成して第二支持部８４を開口ＡＰ２から上方に向かって挿入させて弾性変形の後に挟持する一対の弾性部４４，４４が形成されている。本体部４２の中央側はデッキボード本体２０方向へ膨らんでおり、本体部４２と弾性部４４，４４とが一体的に形成されている。弾性部４４，４４は、本体部４２と繋がって略Ω字状とされ、薄く形成されて弾性を示すようにされ、第二支持部８４への係合時に当該第二支持部８４の一部を囲むように相対向して設けられている。第二係合具４０は、デッキボード本体の凹部２４に形成されたねじ止め用穴に本体部４２のねじ止め用穴４０ａを合わせて凹部２４にねじ止めされて固定される。   As shown in FIG. 8, the second engagement tool 40 is formed with a main body portion 42 having a screwing hole 40 a for screwing into the concave portion 24 of the deck board main body, and is attached to the concave portion 24. A pair of elastic portions 44, 44 are formed that sometimes form an opening AP2 on the lower side and insert the second support portion 84 upward from the opening AP2 to be clamped after elastic deformation. The center side of the main body portion 42 swells toward the deck board main body 20, and the main body portion 42 and the elastic portions 44, 44 are integrally formed. The elastic portions 44, 44 are connected to the main body portion 42 to be substantially Ω-shaped, are thinly formed to exhibit elasticity, and are part of the second support portion 84 when engaged with the second support portion 84. So as to surround each other. The second engagement tool 40 is fixed by being screwed into the recess 24 by aligning the screwing hole 40a of the main body portion 42 with the screwing hole formed in the recess 24 of the deck board body.

一対の第三支持部（外部の構成体）８６，８６に取り付けられる一対の第三係合具（連結部材）５０，５０は、後側ボード２０ｂの第二凹部２６，２６に取り付けられて固定され、一対の第三支持部の係合穴８７，８７に対して上方から近接して着脱可能に係合する。各第三係合具５０，５０は、第三支持部８６，８６に対して第三支持部の係合穴８７，８７に上方から挿入して弾性変形の後に着脱可能に係合する可動部材５６，５６と、第二凹部２６，２６に取り付けられて固定されて可動部材５６，５６を所定範囲で前後方向へ位置を変更可能に保持する保持部材５２，５２とを有している。保持部材５２，５２や可動部材５６，５６は、例えば、熱可塑性樹脂等の合成樹脂を保持部材や可動部材の形状に成形することにより形成することができる。各第三係合具５０，５０は、デッキボード本体の下面２０ｄから下方へ突出しないよう、当該下面と略面一となるように各第二凹部２６，２６に取り付けられている。   A pair of third engagement tools (connecting members) 50 and 50 attached to the pair of third support portions (external components) 86 and 86 are attached and fixed to the second recesses 26 and 26 of the rear board 20b. Then, they are detachably engaged with the engagement holes 87, 87 of the pair of third support portions in proximity to each other from above. Each of the third engagement tools 50, 50 is a movable member that is inserted into the engagement holes 87, 87 of the third support portion from above with respect to the third support portions 86, 86, and is detachably engaged after elastic deformation. 56 and 56, and holding members 52 and 52 that are fixedly attached to the second recesses 26 and 26 and hold the movable members 56 and 56 so that their positions can be changed in the front-rear direction within a predetermined range. The holding members 52 and 52 and the movable members 56 and 56 can be formed, for example, by molding a synthetic resin such as a thermoplastic resin into the shape of the holding member or the movable member. Each of the third engagement tools 50 and 50 is attached to each of the second recesses 26 and 26 so as to be substantially flush with the lower surface so as not to protrude downward from the lower surface 20d of the deck board body.

図９に示すように、保持部材５２は、補強材２９にねじ止めするためのねじ止め用穴５０ａを有する補強材連結部５３と、第二凹部２６に取り付けられたときに下面５４ｂが補強材連結部５３の下面５３ａよりも表側へ一段上がるとともに第二凹部２６との間で隙間ＣＬ１を形成する可動部材保持部５４とが一体的に形成されている。可動部材保持部５４の上面は第二凹部２６の下面から一段下がっており、これにより前記隙間ＣＬ１が形成される。可動部材保持部５４には、車幅方向よりも前後方向の方が長い長穴とされた貫通穴５４ａが形成されている。可動部材５６は、水平方向のどの向きにおいても貫通穴５４ａの車幅方向の長さよりも大きくされて第二凹部２６と可動部材保持部５４との間で前後方向へ所定範囲内でスライド可能に設けられる頭部５７と、当該頭部から下方へ延出して貫通穴５４ａを貫通するとともに第三支持部の係合穴８７に上方から挿入して弾性変形の後に第三支持部８６に係合する係合片５８とが一体的に形成されている。各係合片５８は、細く形成されて弾性を示すようにされ、下端部は外側となるほど上側となるような曲面形状５８ａとされている。全ての係合片５８をまとめたときの径は、貫通穴５４ａの車幅方向の長さよりも小さくされている。可動部材の係合片５８を貫通穴５４ａに貫通させて保持部材５２を第二凹部２６に取り付けると、可動部材の頭部５７が第二凹部２６と保持部材５２との間に挟まれ、隙間ＣＬ１から脱落しないようにされている。これにより、可動部材の脱落を防止する構造を別途設ける必要が無くなる。そして、可動部材５６は、貫通穴５４ａの前後方向の長さで決まる所定範囲内で前後方向へスライド可能に保持される。これにより、デッキボード本体に前後方向の寸法誤差が生じても、可動部材５６が前後方向へスライドすることにより第三支持部の係合穴８７と係合することができる。
なお、貫通穴５４ａが前後方向よりも車幅方向の方が短くされているのは、二重壁成形体の成形後の収縮に関わらない金属製の補強材の両端部に保持部材が取り付けられているため、車幅方向には第三係合具間の寸法が高精度に保たれるからである。これにより、係合片５８は車幅方向にはずれず、係合穴８７に挿入されるときに前後方向へスムーズに誘導され、係合することができる。 As shown in FIG. 9, the holding member 52 has a reinforcing material connecting portion 53 having a screwing hole 50 a for screwing to the reinforcing material 29, and a lower surface 54 b when the second concave portion 26 is attached. A movable member holding part 54 is formed integrally with the lower surface 53a of the connecting part 53 so as to rise one step to the front side and form a gap CL1 with the second recessed part 26. The upper surface of the movable member holding portion 54 is lowered by one step from the lower surface of the second concave portion 26, thereby forming the gap CL1. The movable member holding portion 54 is formed with a through hole 54a that is a long hole that is longer in the front-rear direction than in the vehicle width direction. The movable member 56 is made larger than the length of the through hole 54a in the vehicle width direction in any horizontal direction, and is slidable within a predetermined range in the front-rear direction between the second recess 26 and the movable member holding portion 54. A head 57 provided, extends downward from the head and penetrates the through hole 54a, and is inserted into the engagement hole 87 of the third support portion from above to engage with the third support portion 86 after elastic deformation. The engaging piece 58 is integrally formed. Each engagement piece 58 is formed to be thin and exhibit elasticity, and has a curved surface shape 58a in which the lower end portion becomes the upper side as it becomes the outer side. The diameter when all the engagement pieces 58 are gathered is made smaller than the length of the through hole 54a in the vehicle width direction. When the engaging member 58 of the movable member is passed through the through hole 54a and the holding member 52 is attached to the second recess 26, the head 57 of the movable member is sandwiched between the second recess 26 and the holding member 52, and the gap It is made not to fall off from CL1. This eliminates the need to separately provide a structure for preventing the movable member from falling off. The movable member 56 is held slidable in the front-rear direction within a predetermined range determined by the length in the front-rear direction of the through hole 54a. Thereby, even if a dimensional error in the front-rear direction occurs in the deck board body, the movable member 56 can be engaged with the engagement hole 87 of the third support portion by sliding in the front-rear direction.
Note that the through hole 54a is shorter in the vehicle width direction than in the front-rear direction because the holding members are attached to both ends of the metal reinforcing material regardless of the shrinkage after forming the double wall molded body. This is because the dimension between the third engagement tools is maintained with high accuracy in the vehicle width direction. Thereby, the engagement piece 58 does not shift in the vehicle width direction, but can be smoothly guided and engaged in the front-rear direction when inserted into the engagement hole 87.

第三係合具５０は、可動部材の係合片５８を上方から貫通穴５４ａに挿入した状態で、第二凹部２６に露出した補強材の端部２９ａに形成されたねじ止め用穴に補強材連結部５３のねじ止め用穴５０ａを合わせて補強材２９にねじ止めされて固定される。これにより、補強材に固定された第三係合具を荷室の両側壁に形成された第三支持部に係合を繰り返すときのデッキボードの耐久性を向上させ、左右の第三係合具５０，５０間の距離がずれにくいという利点が得られる。   The third engagement tool 50 is reinforced in a screwing hole formed in the end portion 29a of the reinforcing material exposed in the second recess 26 with the engagement piece 58 of the movable member inserted into the through hole 54a from above. The screwing holes 50a of the material connecting portion 53 are combined and screwed to the reinforcing material 29 to be fixed. This improves the durability of the deck board when the third engagement tool fixed to the reinforcing material is repeatedly engaged with the third support portions formed on both side walls of the cargo compartment, and the right and left third engagement The advantage that the distance between the tools 50 and 50 is difficult to shift is obtained.

（３）自動車用デッキボードの作用、効果：
デッキボード１０を支持部材８２および第三支持部８６に取り付けるとき、最初の段階では、前後ボード２０ａ，ｂを折り畳んだ状態とすることができ、前側ボード２０ａを下側にしながら折り畳んだデッキボード１０の後側を少し持ち上げ気味にして、前縁部２０ｅをコ字状支持部材８２，８２に近づける。そして、図１２に示すように第一係合具の傾斜面３４ａ，３４ａを第二支持部８４上に載置し、支持部材８２上でデッキボード１０を前方へ滑らせていく。すると、デッキボード１０は支持部材の架橋部８５上をスライドしていき、図１３に示すように、第一係合具と凹部とで形成される開口ＡＰ１に対して第一支持部８３が自然に入り、基部３４が第一支持部８３に突き当たるとそれ以上前進しなくなって位置決めされる。このとき、第一係合具３０は弾性変形することなく第一支持部８３を基部３４に当接するまで誘導する。その結果、第一係合具３０，３０は、比較的前側で荷室の両側壁に立設された第一支持部８３，８３に対して円滑に挟み込むことにより着脱可能に係合する。このように、本デッキボードは、傾斜面３４ａがあることによって、荷室に対する取付操作をスムーズに行うことが可能となる。また、第一係合具が弾性変形することなく凹部とで第一支持部を挟み込むので、第一支持部への係合時に加える力が少なくて済む。さらに、第一係合具が前方に開口を形成するので、第一支持部と係合する位置によってデッキボード本体の寸法ばらつきが吸収されるとともに、デッキボードを傾けても第一支持部から脱落しない。
ここで、第一係合具３０，３０は第一支持部への係合時に第一支持部の双方を通る車幅方向を回転軸ＡＸ１として回転動作可能とされるので、第一係合具を固定したデッキボード本体２０は、前記回転軸ＡＸ１を中心として回転操作可能とされる。これにより、第一支持部を中心としてデッキボード１０を開閉操作すれば、デッキボードを完全には取り外さずにデッキボードの下の荷室ＳＰ３に対して大きな物の出し入れをすることができ、本デッキボードは便利である。 (3) Action and effect of car deck board:
When the deck board 10 is attached to the support member 82 and the third support portion 86, the front and rear boards 20a and 20b can be folded in the initial stage, and the deck board 10 folded while the front board 20a is placed downward. The rear side is slightly lifted and the front edge 20e is brought close to the U-shaped support members 82,82. Then, as shown in FIG. 12, the inclined surfaces 34 a and 34 a of the first engagement tool are placed on the second support portion 84, and the deck board 10 is slid forward on the support member 82. Then, the deck board 10 slides on the bridging portion 85 of the support member, and as shown in FIG. 13, the first support portion 83 is naturally located with respect to the opening AP1 formed by the first engagement tool and the recess. Then, when the base portion 34 abuts against the first support portion 83, the base portion 34 is moved forward and positioned. At this time, the first engagement tool 30 guides the first support portion 83 until it abuts against the base portion 34 without elastic deformation. As a result, the first engagement tools 30 and 30 are detachably engaged with each other by smoothly sandwiching the first support portions 83 and 83 that are provided upright on both side walls of the cargo compartment on the relatively front side. Thus, the present deck board can be smoothly attached to the cargo compartment due to the inclined surface 34a. In addition, since the first support part is sandwiched between the recess and the first engagement tool without being elastically deformed, less force is applied when engaging the first support part. Furthermore, since the first engagement tool forms an opening forward, the dimensional variation of the deck board body is absorbed by the position where it engages with the first support part, and even if the deck board is tilted, it will fall off the first support part. do not do.
Here, since the first engagement tools 30 and 30 can be rotated about the rotation axis AX1 in the vehicle width direction passing through both of the first support sections when engaged with the first support section, the first engagement tools The deck board body 20 to which is fixed can be rotated around the rotation axis AX1. As a result, if the deck board 10 is opened and closed with the first support portion as the center, a large object can be taken in and out of the cargo room SP3 under the deck board without completely removing the deck board. A deck board is convenient.

次に、図１３の矢印に示すように、第一支持部に係合したデッキボード１０の後側を下げるようにデッキボード１０を回転操作し、第一係合具３０，３０よりも後側で前側ボード２０ａに取り付けられた第二係合具４０，４０を、比較的後側で荷室の両側壁に立設された第二支持部８４，８４に対して上方から近接させる。なお、このときにコ字状支持部材の架橋部８５が第一係合具の溝３２ａに挿入していく。すると、弾性を有する各弾性部４４は、下端が第二支持部８４に接触すると互いに離反する方向へ撓み、その後、第二支持部８４が本体部４２に突き当たると弾性により元の形状に復元して、第二支持部８４に係合する。第二係合具４０，４０が第二支持部８４に対して弾性変形の後に着脱可能に係合するので、支持部材８２に対して一対の弾性部を上から嵌め込むという簡単な操作でデッキボード１０を円滑に取り付けることができる。また、コ字状支持部材の架橋部８５，８５上に凹部２４，２４が載置されて、デッキボード１０はコ字状支持部材８２，８２上に安定して載置される。そして、第二係合具４０が弾性を示して第二支持部８４と係合するので、自動車走行中の振動によるがたつきが無くなり、異音が生じない。   Next, as shown by the arrow in FIG. 13, the deck board 10 is rotated so as to lower the rear side of the deck board 10 engaged with the first support portion, and the rear side of the first engagement tools 30 and 30. Then, the second engaging tools 40, 40 attached to the front board 20a are brought close to the second support portions 84, 84 provided upright on both side walls of the cargo compartment on the relatively rear side. At this time, the bridging portion 85 of the U-shaped support member is inserted into the groove 32a of the first engagement tool. Then, each elastic part 44 having elasticity bends away from each other when the lower end comes into contact with the second support part 84, and then, when the second support part 84 abuts against the main body part 42, it is restored to its original shape by elasticity. The second support portion 84 is engaged. Since the second engaging tools 40, 40 are detachably engaged with the second support portion 84 after elastic deformation, the deck can be easily operated by fitting a pair of elastic portions into the support member 82 from above. The board 10 can be smoothly attached. Further, the recesses 24 and 24 are placed on the bridging portions 85 and 85 of the U-shaped support member, and the deck board 10 is stably placed on the U-shaped support members 82 and 82. And since the 2nd engagement tool 40 shows elasticity and it engages with the 2nd support part 84, the rattling by the vibration during driving | running | working of a motor vehicle is eliminated, and an abnormal noise does not arise.

さらに、前側ボード２０ａ上に載置されている後側ボード２０ｂを後側へ回動させる操作を行い、後側ボード２０ｂに取り付けられた第三係合具５０，５０を、荷室の両側壁に形成された段差形状の第三支持部８６に上方から近接させる。ここで、第三係合具の可動部材５６は、所定範囲で前後方向へ位置を変更可能とされ、係合片５８の下端部が外側となるほど上側となる曲面形状に形成されているので、デッキボード本体２０に前後方向の寸法誤差があっても、座ぐり状に形成された係合穴８７に対して前後方向に誘導され、自然と係合穴８７に挿入する。すると、弾性を有する各係合片５８は、互いに近接する方向へ撓み、その後、下端部が係合穴８７を乗り越えると弾性により元の形状に復元して、第三支持部８６に係合する。これにより、図６に示すように、デッキボード１０が荷室ＳＰ１に取り付けられる。   Further, the rear board 20b placed on the front board 20a is rotated to the rear side, and the third engagement tools 50, 50 attached to the rear board 20b are attached to both side walls of the cargo compartment. It is made to adjoin from the upper part to the 3rd support part 86 of the level | step difference shape formed in this. Here, since the movable member 56 of the third engagement tool can be changed in position in the front-rear direction within a predetermined range, and is formed in a curved surface shape that becomes the upper side as the lower end portion of the engagement piece 58 becomes the outer side, Even if the deck board 20 has a dimensional error in the front-rear direction, the deck board 20 is guided in the front-rear direction with respect to the engagement hole 87 formed in a counterbore shape and is naturally inserted into the engagement hole 87. Then, each of the engaging pieces 58 having elasticity bends in a direction approaching each other, and thereafter, when the lower end portion gets over the engaging hole 87, it is restored to its original shape by elasticity and is engaged with the third support portion 86. . Thereby, as shown in FIG. 6, the deck board 10 is attached to the luggage compartment SP1.

一方、デッキボードを支持部材８２および第三支持部８６から取り外すとき、図６の矢印に示すように、まず、後側ボード２０ｂの後側を上げるようにして後側ボード２０ｂを回動操作し、第三支持部の係合穴８７，８７から第三係合具５０，５０の係合片を弾性変形の後に引き抜かせる。このとき、各係合片５８は互いに近接する方向へ撓んで係合穴８７を乗り越えた後、弾性により元の形状に復元する。そして、後側ボード２０ｂを前側ボード２０ａ上に重ね合わせる。次に、折り畳んだデッキボード１０の後側を上げるようにデッキボード１０を回転操作し、第二支持部８４，８４から第二係合具４０，４０を弾性変形の後に引き抜かせる。このとき、各弾性部４４は、互いに離反する方向へ撓んで第二支持部８４を乗り越えた後、弾性により元の形状に復元する。そして、第一支持部８３，８３に対して挟み込んだ方向とは反対の後方斜め上方向へデッキボード１０を引く操作を行い、第一支持部８３，８３から第一係合具３０，３０の係合を解除させる。これにより、デッキボード１０が荷室ＳＰ１から取り外される。
以上説明したように、デッキボード本体には前後方向に上述した三種類の係合具が取り付けられているので、デッキボードが重かったりデッキボードの前縁部まで手が届かなかったりしても各係合具を順に係合させることができ、取付操作を容易に行うことができる。また、デッキボード本体の前後方向に寸法誤差が吸収され、デッキボードを確実に各支持部に取り付けることができる。従って、デッキボードの着脱操作をより円滑にさせることができ、自動車走行中の振動によるがたつきを無くし、異音の発生を防ぐことが可能な自動車用デッキボードを提供することができる。 On the other hand, when the deck board is removed from the support member 82 and the third support portion 86, first, as shown by the arrow in FIG. 6, the rear board 20b is rotated so that the rear side of the rear board 20b is raised. The engagement pieces of the third engagement tools 50, 50 are pulled out from the engagement holes 87, 87 of the third support portion after elastic deformation. At this time, the engagement pieces 58 are bent in directions close to each other and get over the engagement holes 87, and then are restored to their original shapes by elasticity. Then, the rear board 20b is overlaid on the front board 20a. Next, the deck board 10 is rotated so as to raise the rear side of the folded deck board 10, and the second engagement tools 40, 40 are pulled out from the second support portions 84, 84 after elastic deformation. At this time, the elastic portions 44 are bent in directions away from each other and get over the second support portion 84, and then are restored to the original shape by elasticity. Then, an operation of pulling the deck board 10 in the rear obliquely upward direction opposite to the direction sandwiched with respect to the first support portions 83, 83 is performed, and the first engagement tools 30, 30 are moved from the first support portions 83, 83. Release the engagement. Thereby, the deck board 10 is removed from the luggage compartment SP1.
As explained above, since the above-mentioned three types of engagement tools are attached to the deck board body in the front-rear direction, each deck board is heavy or even if it does not reach the front edge of the deck board. The engaging tools can be sequentially engaged, and the attachment operation can be easily performed. Further, dimensional errors are absorbed in the front-rear direction of the deck board body, and the deck board can be securely attached to each support portion. Accordingly, it is possible to provide an automotive deck board that can smoothly attach and detach the deck board, eliminate rattling due to vibration during traveling of the automobile, and can prevent the generation of abnormal noise.

蓋体２１０は、二重壁成形体２２２と補強材２２８と一対の連結部材２３０，２３０を有している。
二重壁成形体２２２は、少なくとも樹脂を有する素材をブロー成形することにより、間隔をおいて対向する表壁２２２ａおよび裏壁２２２ｂと当該表壁および当該裏壁の周縁部を閉塞して中空部ＨＯ５を形成する周囲壁２２２ｃとが形成された成形体とされている。
蓋体２１０の裏面には、両縁部で上方へ凹んだ一対の凹部２２４，２２４が形成されている。凹部２２４，２２４の幅方向内側の面には補強材２２８の両端部を突き出させて露出させる開口が形成されている。
外部の構成体であるフロア体２９０では、収納部２９１が床面２９２から下がった陥没状に形成されており、収納部２９１の開口の周縁部は蓋体２１０を落とし込んで載置するための受け段部２９３とされている。受け段部２９３において蓋体２１０の連結部材２３０，２３０が載置される部分には、上方に向かって突出した嵌合凸部２９４，２９４が形成されている。 The lid 210 includes a double wall molded body 222, a reinforcing material 228, and a pair of connecting members 230 and 230.
The double wall molded body 222 is formed by blow molding a material having at least a resin so as to close the front wall 222a and the back wall 222b opposed to each other with a space therebetween and the peripheral portion of the front wall and the back wall to close the hollow portion. The molded body is formed with a peripheral wall 222c that forms HO5.
A pair of recesses 224 and 224 that are recessed upward at both edges are formed on the back surface of the lid 210. Openings that project and expose both end portions of the reinforcing material 228 are formed on the inner surfaces of the recesses 224 and 224 in the width direction.
In the floor body 290 that is an external component, the storage portion 291 is formed in a depressed shape that is lowered from the floor surface 292, and the peripheral portion of the opening of the storage portion 291 is a receiver for dropping and placing the lid 210. A step portion 293 is provided. In the receiving step portion 293, fitting convex portions 294 and 294 projecting upward are formed on the portion where the connecting members 230 and 230 of the lid 210 are placed.

二重壁成形体２２２には、二重壁成形体の成形後の冷却収縮に関わらない材質からなる補強材２２８を挿通している。本参考例の補強材２２８は、真っ直ぐな角筒状の金属製パイプとしている。補強材２２８の両端部は蓋体２１０の両側縁部よりも幅方向内側とされて凹部２２４内で露出している。従って、補強材２２８の両端部は、二重壁成形体２２２の両端面から突出しないようになっている。
なお、二重壁成形体２２２内には補強材２２８を長手方向にのみスライド可能に支持するためのインナーリブおよび複数の突起が形成されており、補強材２２８は長手方向を幅方向に向けて中空部ＨＯ５内に挿通されて二重壁成形体に対して長手方向にのみスライド可能に支持されている。 A reinforcing material 228 made of a material that is not related to cooling shrinkage after molding of the double wall molded body is inserted into the double wall molded body 222. The reinforcing material 228 of the present reference example is a straight square cylindrical metal pipe. Both ends of the reinforcing member 228 are exposed in the width direction from both side edges of the lid 210 and are exposed in the recess 224. Therefore, both end portions of the reinforcing material 228 do not protrude from both end surfaces of the double wall molded body 222.
An inner rib and a plurality of protrusions are formed in the double wall molded body 222 to support the reinforcing member 228 so as to be slidable only in the longitudinal direction. The reinforcing member 228 has the longitudinal direction directed in the width direction. It is inserted into the hollow portion HO5 and supported so as to be slidable only in the longitudinal direction with respect to the double wall molded body.

一対の連結部材２３０，２３０は、凹部２２４，２２４に取り付けられて固定され、嵌合凸部２９４，２９４に対して着脱可能に係合する。連結部材２３０は、例えば、熱可塑性樹脂等の弾性を示す合成樹脂を連結部材の形状に成形することにより形成することができる。
連結部材２３０は、補強材２２８の端部を開口から挿入させて補強材２２８の端部と嵌合する補強材嵌合部２３２と、図２３において補強材嵌合部２３２の左横に設けられた基部２３４と、嵌合凸部２９４の一に合わせて開口させて形成した嵌合凹部２３６とが一体的に形成されている。そして、フロア体２９０に連結するため、補強材２２８の両端部に連結部材２３０，２３０が取り付けられている。
連結部材２３０は、凹部２２４に挿入して当該凹部で露出した補強材２２８の端部に補強材嵌合部２３２を嵌め合わせることにより、補強材２２８の端部に抱持状態で固定されて凹部２２４に取り付けられる。 The pair of connecting members 230 and 230 are fixedly attached to the concave portions 224 and 224, and are detachably engaged with the fitting convex portions 294 and 294. The connecting member 230 can be formed, for example, by molding a synthetic resin exhibiting elasticity such as a thermoplastic resin into the shape of the connecting member.
The connecting member 230 is provided on the left side of the reinforcing material fitting portion 232 in FIG. 23, and the reinforcing material fitting portion 232 in which the end portion of the reinforcing material 228 is inserted from the opening and fitted to the end portion of the reinforcing material 228. The base portion 234 and the fitting concave portion 236 formed so as to open in accordance with one of the fitting convex portions 294 are integrally formed. And in order to connect with the floor body 290, the connection members 230 and 230 are attached to the both ends of the reinforcing material 228.
The coupling member 230 is inserted into the recess 224 and fitted into the end of the reinforcing member 228 exposed in the recess so as to be fixed to the end of the reinforcing member 228 in a holding state. 224 is attached.

嵌合凹部２３６，２３６の位置を嵌合凸部２９４，２９４の位置に合わせて上から蓋体２１０を受け段部２９３に押し込むと、嵌合凹部２３６，２３６と嵌合凸部２９４，２９４とが嵌合し、蓋体２１０がフロア体２９０に取り付けられる。一方、フロア体２９０に取り付けられた蓋体２１０を上方へ引っ張ると、嵌合凹部２３６，２３６から嵌合凸部２９４，２９４が抜け、蓋体２１０がフロア体２９０から取り外される。   When the positions of the fitting recesses 236 and 236 are adjusted to the positions of the fitting projections 294 and 294 and the lid 210 is received from above and pushed into the stepped portion 293, the fitting recesses 236 and 236 and the fitting projections 294 and 294 And the lid 210 is attached to the floor body 290. On the other hand, when the lid 210 attached to the floor body 290 is pulled upward, the fitting protrusions 294 and 294 are removed from the fitting recesses 236 and 236, and the lid 210 is detached from the floor body 290.

従来、樹脂製中空二重壁構造体を外部の構成体に連結する際には、外部構成体の支持具に連結させる連結具を熱可塑性樹脂からなる包囲壁に取り付けていた。しかし、連結具を樹脂製中空二重壁構造体の包囲壁に取り付けると、成形後の冷却収縮の影響を受けて連結具に位置ずれが生じ、樹脂製中空二重壁構造体の着脱操作を円滑に行うことができないことがあった。本参考例においては、樹脂の二重壁成形体内に挿入された補強材２２８は金属製など二重壁成形体の成形後の冷却収縮に関わらない材質のものであるから、補強材２２８の両端部に取り付けられている連結部材の嵌合凹部２３６，２３６と嵌合凸部２９４，２９４との相対的な位置関係にずれを起こすことはない。従って、二重壁成形体の寸法誤差による樹脂製中空二重壁構造体の外部構成体への連結性低下を防ぐことができる。
以上説明したように、本発明及び本参考例によると、種々の態様により、有用な自動車用デッキボードおよび樹脂製中空二重壁構造体を提供することができる。 Conventionally, when a resin hollow double-wall structure is connected to an external component, a connector to be connected to a support of the external component is attached to the surrounding wall made of a thermoplastic resin. However, when the connector is attached to the surrounding wall of the resin hollow double-wall structure, the connector is displaced due to the effect of cooling shrinkage after molding, and the resin hollow double-wall structure is attached and detached. Sometimes it could not be done smoothly. In this reference example , the reinforcing material 228 inserted into the resin double-wall molded body is made of a material such as metal that is not related to cooling shrinkage after the molding of the double-wall molded body. There is no deviation in the relative positional relationship between the fitting recesses 236, 236 and the fitting projections 294, 294 of the connecting member attached to the part. Therefore, it is possible to prevent a decrease in the connectivity of the resin hollow double wall structure to the external structure due to a dimensional error of the double wall molded body.
As described above, according to the present invention and the present reference example , a useful automobile deck board and a resin hollow double wall structure can be provided according to various aspects.
