Description

【0001】
【発明の属する技術分野】
本発明は、車両,特に、商用車の荷台に用いられている樹脂製の煽り板の取付構造に係り、特に、熱変形による影響を抑えた煽り板の取付構造に関する。
【0002】
【従来の技術】
一般に、商用車用の煽り板(gate board)は、アッパフレーム,ロアフレーム,サイドフレーム,外板パネル及び内板パネル等の部品からなり、荷台の側面や後面のサイドレールにヒンジ結合されて配設される。この煽り板は、積載物の保護や脱落防止を目的としているため、特に、内板パネルは積載物と接触した際に積載物を傷付けない構造のものが必要であり、従来技術では木製合板や木製無垢材が使用されている。また、脱落防止のため煽り板はサイドレール側に確実にヒンジ結合されている。実開平2−117271号公報の「トラックの荷台煽構造」には内板パネルとして木製ボード又は鋼製のステフナを併用し得る煽構造が開示されている。
【0003】
【発明が解決しようとする課題】
最近では、環境保護への関心が高まり、リサイクル推進の傾向から、マテリアルリサイクルが困難な木製材からなる煽り板の替りにリサイクルが可能で、かつ軽量な樹脂製内板パネルを用いた煽り板が使用されてきている。例えば、実開昭58−86770号公報や特開平8−133136号公報が挙げられる。実開昭58−86770号公報の「貨物自動車の荷物台」は内面側にプラスチック板を設け、かつその上縁にゴム製のプロテクタを設けたものであるが、該プロテクタはプラスチック板や荷物に傷が付くのを防止するためのものであり、プラスチック板の熱変形による影響を防止するためのものではない。
【0004】
一方、特開平8−133136号公報の「樹脂製ボードの取付構造」には、種々の形状の樹脂製ボードが開示されている。すなわち、樹脂製ボ−ドのごとき内板パネルが金属製フレームのごとき補助フレームにより挟持されているものや、外板のフランジに樹脂製ボードを段付ボルトにより固定する型式のものが開示されている。この内、フランジの内面側に樹脂製ボードを段付ボルトを用いて取り付ける取付構造のものは、段付ボルトと樹脂製ボードとの間に樹脂製ボードの熱変形時における両者の干渉を防止するための長孔が形成されている点に特徴を有する。しかしながら、この取付構造の場合においても、樹脂製ボードが直接段付ボルトにより締め付けられ、この締め付け部位は熱変形時には樹脂製ボードの自由変形を拘束する。また、煽り板の内面側に前記の段付ボルトの頭部が露出する。
【0005】
前記したような事情により、煽り板としては内板パネルに樹脂材を使用することが要請されているが、熱変形が大きいため、煽り板がサイドフレーム側と干渉して変形し、外観品質を低下し、高品質化を損う恐れがある。本発明は、以上の事情に鑑みて創案されたものであり、内板パネルに樹脂製内板パネルを採用すると共に熱変形による影響を抑え、かつ外観品質の向上を図る煽り板の取付構造を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明は、以上の目的を達成するために、サイドレールに下方側をヒンジ結合し、上方にアッパフレーム,下方にロアフレーム,側方にサイドフレームを備え、これ等のフレーム内の外面側に外板パネル,内面側に樹脂製内板パネルを備えてなる煽り板の取付構造であって、前記樹脂製内板パネルは、その上方部を前記アッパフレームに係着して垂下支持され、下方部を押さえパネルを介して前記ロアフレーム側に保持されると共に、前記樹脂製内板パネルと煽り板の他の部材との間には、常温及び熱変形時において相互干渉が生じない間隙が形成される煽り板の取付構造を構成するものである。更に具体的に、前記アッパフレーム及びロアフレームと前記外板パネルとはねじ結合され、前記樹脂製内板パネルの前記外板パネル側には前記ねじ結合するねじ部材と前記樹脂製内板パネルとの干渉を防止するための凹溝が形成されることを特徴とする。また、前記押さえパネルは、前記樹脂製内板パネルの内面と適宜間隙を介して配設される押さえ板部と、該押さえ板部と一体に形成され前記ロアフレーム側に端部を当接する当接板部とからなり、前記押さえ板部には段付ビスの頭部が当る座ぐり面が形成され、前記段付ビスは前記ロアフレーム側に螺着され、前記樹脂製内板パネルには、前記段付ビスのねじ部の緩通する貫通孔が形成されることを特徴とする。
【0007】
また、前記外板パネルと前記樹脂製内板パネルとは適宜間隙を介して配置されるものであり、前記樹脂製内板パネルの両サイドとこれを囲むサイドフレームとの間には間隙が形成され、この間隙内には該間隙をうめる軟質樹脂部材が介設されることを特徴とする。
【0008】
また、前記樹脂製内板パネルの熱変化が、常温20℃から上限+60℃,下限−50℃の範囲であることを特徴とする。また、前記樹脂製内板パネルは、熱可塑性樹脂材からなることを特徴とするものである。
【0009】
熱可塑性樹脂等からなる樹脂製内板パネルはアッパフレーム側に垂下支持されると共に、押さえパネルによってロアフレーム側に保持されて外板パネル側と適宜の間隔を介して保持される。樹脂製内板パネルは以上のようにして外板パネルに近接して保持されるが、特に、外板パネル側との干渉部分のほとんどすべての場所において熱変形時において両者が干渉しないように配慮されている。そのため、熱変形が生じても外観美を損うような変形が生じない。また、樹脂製内板パネルはそれ自体として熱変形しにくい構造からなり、かつ締め付け用ねじ部等が内面側に露出しない工夫がされている。以上により、熱変形による影響を抑えると共に、外観美の向上を図ることができる。
【0010】
【発明の実施の形態】
以下、本発明の煽り板の取付構造の実施の形態を図面を参照して詳述する。図1に示すように、煽り板1は、大別してアッパフレーム2と、ロアフレーム3と、両フレームの両サイドを連結するサイドフレーム4,4(図4)と、アッパフレーム2,ロアフレーム3及びサイドフレーム4,4で囲まれた空間内に配設される外板パネル5,該外板パネル5と相対向して配設される樹脂製内板パネル6等とからなる。なお、本例では樹脂製内板パネル6は熱可塑性樹脂材からなる。図1に示すように、外板パネル5と樹脂製内板パネル6との間にはメンバ7が介設される。また、図1及び図4に示すように煽り板1はその下端側をサイドレール8にヒンジ9により連結され、開閉自在にサイドレール8側に支持される。
【0011】
図1に示すように、アッパフレーム2は、枠体状の横断面を有する部材からなり、その下方側に伸延する平坦なフランジ部10は、外板パネル5とメンバ7の上縁にボルト11及びナット12により固定される。一方、ロアフレーム3は同じく枠体状の横断面を有する部材からなり、その上方側に伸延するフランジ部13は、外板パネル5とメンバ7の下縁にボルト14及びナット15により固定される。なお、ロアフレーム3とメンバ7との間にはヒンジ9の基端側が挟持され、ヒンジ9の下端はピン16によりサイドレール8にピン支持される。
【0012】
図1,図3,図4に示すように、樹脂製内板パネル6は長方形状の平板状部材からなり、その横断面は図3(a)に示すように角断面のものからなり、反りが生じ難い輪郭形状のものからなる。樹脂製内板パネル6は上下の端縁に段付状平坦部17,18を形成し、その段付状平坦部17,18間の内面側は平坦面19を形成するものからなる。なお、上方の段付状平坦部17と平坦面19との合致する段付部には凹部20が形成される。この凹部20にはアッパフレーム2の折曲部21が係着される。また、樹脂製内板パネル6の裏面側のナット12,15等と相対向する位置には凹溝22,23が凹設される。なお、図3には長穴状の凹溝22,23の形状が示されている。また、下方の段付状平坦部18には貫通孔24が形成される。なお、貫通孔24は図3(b)に示すように長孔状に形成される。
【0013】
次に、図1及び図2に示す押さえパネル25の構造を説明する。押さえパネル25は、図に示すように、組み付け時に下方の段付状平坦部18と相対向する位置に配設される押さえ板部26と、押さえ板部26と一体構造に屈曲形成され組み付け時にヒンジ9の内面側と当接する当接面27を有する当接板部28とからなる。なお、押さえ板部26には組み付け時において樹脂製内板パネル6の貫通孔24と相対向する位置に座ぐり面29が形成される。なお、図2に示すように、段付ビス30はその頭部31を座ぐり面29に当接して配置され、そのねじ部32は貫通孔24及びメンバ7の貫通孔33を通り、ヒンジ9のねじ孔34に螺着される。
【0014】
次に、図1により樹脂製内板パネル6等の組み立て構造について説明する。まず、アッパフレーム2,ロアフレーム3及びサイドフレーム4と外板パネル5及びメンバ7,ヒンジ9等を組み合わせ、前記したようにボルト,ナット11,12、14,15により結合する。次に、アッパフレーム2の折曲部21に樹脂製内板パネル6の凹部20を係止し、樹脂製内板パネル6を垂下支持せしめる。次に、樹脂製内板パネル6の下方の段付状平坦部18の部位に押さえパネル25の押さえ板部26を配置し、その当接板部28の当接面27をヒンジ9の内面に当接せしめる。その状態で段付ビス30を挿入し、頭部31を座ぐり面29に当接せしめた状態でそのねじ部32をヒンジ9のねじ孔34に螺着し、当接面27をヒンジ9に圧接せしめる。
【0015】
以上の組み付け状態において、樹脂製内板パネル6とこれに係合する他の部材との間には適宜間隙が保持される。すなわち、樹脂製内板パネル6とメンバ7との間には間隙35が形成され、凹溝22,23とボルト11,14、ナット12,15との間には間隙36,37が形成される。また、段付ビス30は頭部31が座ぐり面29に当接し、かつ、段付ビス30のねじ部32がヒンジ9のねじ孔34に螺着した状態で、当接面27がヒンジ9に圧接するため、押さえ板部26の移動が制限され、結果として樹脂製内板パネル6の下方の段付状平坦部18と押さえパネル25の押さえ板部26との間には間隙38が形成される。また、貫通孔24と段付ビス30のねじ部32の間には間隙39が形成される。これ等の間隙35,36,37,38,39は、樹脂製内板パネル6が熱変形した場合においてもこの間隙35等が無くならない寸法からなる。なお、本例の樹脂製内板パネル6の熱変形が生ずる温度範囲としては常温20℃から+60℃を上限とし下限を−50℃とする。なお、以上の上下限を越える温度範囲では通常煽り板1は使用されない。また、前記の間隙35等は、図1に図示される方向のみならず、図3(b)に示される平面側においても形成され、熱変形時のこの方向における干渉を防止している。
【0016】
以上により、樹脂製内板パネル6は確実にアッパフレーム2,ロアフレーム3や外板パネル5側に連結されると共に、樹脂製内板パネル6の内面側には一切、何物も露出せず外観美が保持される。また、樹脂製内板パネル6が温度変形により熱変形した場合でも、各部に間隙35等が形成されているため、樹脂製内板パネル6と他の部材との干渉がなく、反り等が生じない。それにより外観美の向上が図れる。
【0017】
図4,図5に示すように、サイドフレーム4,4と樹脂製内板パネル6の両サイドとの間には熱変形時における干渉を防止するため、間隙40,40が形成される。この間隙40,40は外部から見えるため、そのままの状態では外観美を低下させる。そこで、本例ではこの間隙40,40に軟質樹脂部材として軟質発泡成形部材41,41を介設させて間隙40,40をうめる。なお、軟質発泡成形部材41,41は、例えばその一端側を樹脂製内板パネル6に固着し、他端側をサイドフレーム4に圧接した状態で配設される。以上により、外観美の向上が図れる。
【0018】
(実施例)
樹脂製内板パネル6としては各種の材質が使用されるが、ポリプロピレンが一例として採用される。また、軟質発泡成形部材41としては、一例としてエプトシーラー(日東電工(株)製)が採用される。また、樹脂製内板パネル6の板厚としては、一例として15mmが使用される。また、この場合、凹溝22,23としては、その横幅が68mmのものが採用される。また、この場合、貫通孔24としては、横幅50mmで縦幅25mmが採用される。以上により、樹脂製内板パネル6側と他の部分との干渉が防止される。
【0019】

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a resin-made cover plate used for a vehicle, in particular, a loading platform of a commercial vehicle, and more particularly to a structure for mounting a cover plate that suppresses the influence of thermal deformation.
[0002]
[Prior art]
In general, a gate board for a commercial vehicle is composed of parts such as an upper frame, a lower frame, a side frame, an outer plate panel, and an inner plate panel, and is hinged to the side rails of the cargo bed and the rear side rails. Established. This cover plate is intended to protect the load and prevent it from falling off.In particular, the inner panel must have a structure that will not damage the load when it comes into contact with the load. Solid wood is used. In addition, the twist plate is securely hinged to the side rail side to prevent falling off. Japanese Utility Model Laid-Open No. 2-117271 discloses a truck structure in which a wooden board or a steel stiffener can be used in combination as an inner panel.
[0003]
[Problems to be solved by the invention]
Recently, interest in environmental protection has increased, and due to the tendency to promote recycling, it is possible to recycle instead of wooden boards made of wooden materials that are difficult to recycle materials. Has been used. For example, Japanese Utility Model Laid-Open No. 58-86770 and Japanese Patent Application Laid-Open No. 8-133136 are cited. Japanese Utility Model Laid-Open No. 58-86770 discloses a “cargo luggage platform” in which a plastic plate is provided on the inner surface and a rubber protector is provided on the upper edge of the plastic plate. This is to prevent scratches and not to prevent the effects of thermal deformation of the plastic plate.
[0004]
On the other hand, “resin board mounting structure” in JP-A-8-133136 discloses resin boards of various shapes. That is, an inner plate panel such as a resin board is sandwiched between auxiliary frames such as a metal frame, and a type in which a resin board is fixed to a flange of an outer plate with a stepped bolt is disclosed. Yes. Of these, the mounting structure in which the resin board is attached to the inner surface side of the flange using a stepped bolt prevents the interference between the stepped bolt and the resin board when the resin board is thermally deformed. It is characterized in that a long hole is formed. However, even in the case of this mounting structure, the resin board is directly tightened by the stepped bolt, and this tightening portion restrains the free deformation of the resin board at the time of thermal deformation. Moreover, the head part of the said stepped bolt is exposed to the inner surface side of a twist board.
[0005]
Due to the circumstances described above, it is required to use a resin material for the inner plate panel as the cover plate, but since the thermal deformation is large, the cover plate deforms by interfering with the side frame side, and the appearance quality is improved. There is a risk of lowering the quality. The present invention was devised in view of the above circumstances, and employs a resin plate inner plate panel as an inner plate panel, suppresses the influence of thermal deformation, and improves the appearance quality. The purpose is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a lower rail hinged to the side rail, an upper frame on the upper side, a lower frame on the lower side, and a side frame on the side. The outer plate panel is a mounting structure of a cover plate provided with a resin inner plate panel on the inner surface side, and the resin inner plate panel is suspended and supported at its upper part to the upper frame. A gap is formed between the resin inner plate panel and other members of the ribbed plate so that mutual interference does not occur at room temperature and during thermal deformation. It constitutes the mounting structure of the twisted plate. More specifically, the upper frame and the lower frame and the outer plate panel are screwed together, and the screw member to be screwed and the resin inner plate panel are provided on the outer plate panel side of the resin inner plate panel. A concave groove for preventing the interference is formed. In addition, the pressing panel is formed integrally with the pressing plate portion disposed between the inner surface of the resin inner plate panel and an appropriate gap, and the end portion is brought into contact with the lower frame side. The presser plate portion is formed with a counterbore surface against which the head of the stepped screw hits, the stepped screw is screwed to the lower frame side, and the resin inner plate panel A through hole through which the threaded portion of the stepped screw passes is formed.
[0007]
The outer plate panel and the resin inner plate panel are appropriately arranged with a gap therebetween, and a gap is formed between both sides of the resin inner plate panel and the side frame surrounding it. In this gap, a soft resin member that fills the gap is interposed.
[0008]
Moreover, the heat change of the said resin inner board panel is the range of normal temperature 20 degreeC to an upper limit +60 degreeC and a minimum -50 degreeC, It is characterized by the above-mentioned. Further, the resin inner plate panel is made of a thermoplastic resin material.
[0009]
A resin inner plate panel made of a thermoplastic resin or the like is suspended and supported on the upper frame side, and is held on the lower frame side by a pressing panel and is held at an appropriate distance from the outer plate panel side. The resin inner panel is held in close proximity to the outer panel as described above. However, especially in almost all places where there is interference with the outer panel side, care should be taken so that they do not interfere during thermal deformation. Has been. Therefore, even if thermal deformation occurs, there is no deformation that impairs the appearance. Further, the resin inner plate panel itself has a structure that is not easily thermally deformed, and has been devised so that the fastening screw portion or the like is not exposed to the inner surface side. As described above, it is possible to suppress the influence of thermal deformation and improve the appearance beauty.

Appearance beauty is maintained. Further, even when the resin inner plate panel 6 is thermally deformed due to temperature deformation, since the gaps 35 and the like are formed in each part, there is no interference between the resin inner plate panel 6 and other members, and warping or the like occurs. Absent. Thereby, the appearance beauty can be improved.
[0017]
As shown in FIGS. 4 and 5, gaps 40, 40 are formed between the side frames 4, 4 and both sides of the resin inner plate panel 6 in order to prevent interference during thermal deformation. Since the gaps 40 and 40 are visible from the outside, the appearance beauty is deteriorated as it is. Therefore, in this example, the gaps 40, 40 are filled by inserting soft foam molding members 41, 41 as soft resin members in the gaps 40, 40. The soft foam molded members 41, 41 are arranged, for example, with one end thereof fixed to the resin inner panel 6 and the other end pressed against the side frame 4. As described above, the appearance beauty can be improved.
[0018]
(Example)
Various materials are used as the resin inner panel 6, and polypropylene is used as an example. Moreover, as the soft foam molded member 41, for example, EPT SEALER (manufactured by Nitto Denko Corporation) is employed. In addition, as a thickness of the resin inner panel 6, 15 mm is used as an example. In this case, as the concave grooves 22 and 23, those having a lateral width of 68 mm are employed. In this case, the through hole 24 has a width of 50 mm and a length of 25 mm. Thus, interference between the resin inner plate panel 6 side and other portions is prevented.
