Description

本発明は、一般貨物車、災害支援車、放送中継車、医療防疫車などの様々な特装車、あるいはキャンピングカーなどの箱型車両の外折れ式ドア構造物に関する。   The present invention relates to various types of specially equipped vehicles such as general freight vehicles, disaster support vehicles, broadcast relay vehicles, and medical quarantine vehicles, or outer folding door structures of box-type vehicles such as campers.

従来、箱型車両では、例えば図４に示されているように、車両の箱型荷台２１の後方部に、荷物の搬入、搬出のための開口２２が設けられており、開口２２には、この開口２２を開閉する外折れ式ドア２３が設けられている（特許文献１）。   Conventionally, in a box-type vehicle, for example, as shown in FIG. 4, an opening 22 for loading and unloading luggage is provided in a rear portion of the box-type loading platform 21 of the vehicle. An external folding door 23 that opens and closes the opening 22 is provided (Patent Document 1).

特開２００３−０９７１４１号公報Japanese Patent Laid-Open No. 2003-097141

ところで、このような従来の箱型車両の外折れ式ドア構造物では、ローラーベアリング２７の移動案内路となるガイドレール２４は、図５および図６に示したように、その下端部２４ａが床面２５に設けた穴２６の内部に差し込まれている。仮に、下端部２４ａが穴２６内に差し込まれずに床面２５の上に配置されていると、下部ドア２３ｂにより開口２２を完全に封止することができない。   By the way, in such a conventional folding door structure of a box-type vehicle, the guide rail 24 which is a movement guide path of the roller bearing 27 has a lower end portion 24a as shown in FIGS. It is inserted into a hole 26 provided in the surface 25. If the lower end portion 24a is not inserted into the hole 26 and is disposed on the floor surface 25, the opening 22 cannot be completely sealed by the lower door 23b.

そこで、このような構造では、下端部２４ａを穴２６内に差し込まずに開口２２を完全に封止するためには、図５に示したように、床面２５の後部端末部に土手板３５を立ち上げなければならない。   Therefore, in such a structure, in order to completely seal the opening 22 without inserting the lower end 24a into the hole 26, as shown in FIG. Must be launched.

しかし、このように車両の後部に土手板３５を立ち上げると、床面２５が掃き出し式でなくなることから、荷物の出し入れに支障が生じてしまう。
そこで、このような不具合を解消するため、従来は、床面２５に穴２６を設けて、その穴２６にガイドレール２４を埋め込むことで掃き出しの床面を構成していた。 However, when the bank board 35 is raised at the rear part of the vehicle in this way, the floor surface 25 is not swept out, which causes troubles in loading and unloading the luggage.
Therefore, in order to solve such a problem, conventionally, a floor 26 is formed by providing a hole 26 in the floor surface 25 and embedding the guide rail 24 in the hole 26.

本発明は、このような実情に鑑みてなされたもので、一般貨物車、災害支援車、放送中継車、医療防疫車などの様々な特装車、あるいは荷物車などの箱型車両の開口を開閉するにあたり、床面に穴を開けずに掃き出し式の床面を形成することが可能な箱型車両の外折れ式ドア構造物を提供することを目的とする。   The present invention has been made in view of such circumstances, and opens and closes the opening of various specially equipped vehicles such as general freight vehicles, disaster support vehicles, broadcast relay vehicles, and medical quarantine vehicles, or box vehicles such as luggage vehicles. It is an object of the present invention to provide an outwardly folding door structure for a box-type vehicle capable of forming a sweep-out floor without making a hole in the floor.

上記目的を達成するための本発明に係る箱型車両の外折れ式ドア構造物は、
箱型荷台を有する箱型車両の開口を互いに蝶着された上部ドアと下部ドアとからなる外折れ式ドアで開閉する箱型車両の外折れ式ドア構造物であって、
前記上部ドアの上端が前記開口の上端に枢着され、前記下部ドアの下端両側が前記開口の両側に設けられたガイドレールに沿って上下方向に可動に取り付けられる外折れ式ドアと、
前記下部ドアの下端と前記ガイドレールとの間に配置され、前記ガイドレール内に上下方向に移動可能に装着されたリンク機構と、
前記リンク機構を上方に備えるねじりばねによる巻き取りドラムに巻かれて上方に引き上げられる反力ワイヤーと、を有し、
前記反力ワイヤーを介して前記リンク機構を操作することにより前記下部ドアを上方に移動させることにより前記開口を開とし、下方に移動させることにより前記下部ドアを下方に移動させて前記開口を閉とすることを特徴としている。 In order to achieve the above object, an outer folding door structure for a box-type vehicle according to the present invention comprises:
An outer folding door structure for a box type vehicle that opens and closes with an outer folding door composed of an upper door and a lower door that are hinged to each other.
An upper folding door in which the upper end of the upper door is pivotally attached to the upper end of the opening, and both lower ends of the lower door are movably attached in the vertical direction along guide rails provided on both sides of the opening;
A link mechanism disposed between a lower end of the lower door and the guide rail, and mounted in the guide rail so as to be vertically movable;
A reaction wire wound around a winding drum by a torsion spring provided with the link mechanism above and pulled up upward,
By operating the link mechanism via the reaction force wire, the lower door is moved upward to open the opening, and by moving downward, the lower door is moved downward to close the opening. It is characterized by that.

このような本発明によれば、ワイヤー操作によるリンク機構の動作により下部ドアを上下方向に移動させた場合に、リンク機構が下部ドアの下端より上方に位置している状態で、箱型荷台を有する箱型車両の開口が閉となる。   According to the present invention, when the lower door is moved in the vertical direction by the operation of the link mechanism by wire operation, the box-type loading platform is placed in a state where the link mechanism is located above the lower end of the lower door. The opening of the box-type vehicle is closed.

これにより、本発明では、ガイドローラを使用した場合のように、ガイドローラの収納位置を床面の下方に確保する必要がなくなるため、床面に穴を設ける必要がない。したがって、本発明では、床面に穴を開けるという作業が不要となる。   Thus, in the present invention, unlike the case where the guide roller is used, it is not necessary to secure the guide roller storage position below the floor surface, and therefore it is not necessary to provide a hole in the floor surface. Therefore, in this invention, the operation | work which opens a hole in a floor surface becomes unnecessary.

本発明によれば、外折れ式ドアをリンク機構により開閉するようにしたので、床面に穴を設けて、ガイドレールをその穴の中に挿入する作業が不要である。   According to the present invention, since the outer folding door is opened and closed by the link mechanism, it is not necessary to provide a hole in the floor surface and insert the guide rail into the hole.

以下、図面を参照しながら、本発明の好ましい実施の形態（実施例）について説明する。
図１は、本発明の一実施例に係る箱型車両の外折れ式ドア構造物に適用されたリンク機構３０の分解斜視図である。 Hereinafter, preferred embodiments (examples) of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of a link mechanism 30 applied to an outward folding door structure of a box-type vehicle according to an embodiment of the present invention.

なお、本発明の一実施例に係る箱型車両の外折れ式ドア構造物は、図４の場合と同様に、箱型荷台２１の後部側の開口２２を開閉自在に覆うものであり、上部ドア２３ａと下部ドア２３ｂとからなる外折れ式ドア２３を有するものである。よって、図４あるいは図５に用いた要素と同一要素については同一符号を付して詳しい説明を省略する。   The outer folding door structure for a box-type vehicle according to an embodiment of the present invention covers the opening 22 on the rear side of the box-type cargo bed 21 so as to be freely opened and closed, as in FIG. It has an outward folding door 23 composed of a door 23a and a lower door 23b. Therefore, the same elements as those used in FIG. 4 or FIG.

本実施例で使用されるリンク機構３０は、略長方形状の第１の板材３２と、同じく略長方形状の第２の板材３４と、断面略Ｌ字形状の第３の板材３６と、一部が折曲して形成された略長方形状の第４の板材３８と、第１の板材３２に軸支された２本のローラーベアリング４４ａ、４４ｂとを主構成要素とし、これらが平ワッシャー４０および薄平リベット４２などで連結されている（図２、図３参照）。   The link mechanism 30 used in the present embodiment includes a first plate member 32 having a substantially rectangular shape, a second plate member 34 having a substantially rectangular shape, a third plate member 36 having a substantially L-shaped cross section, and a part thereof. The main component is a substantially rectangular fourth plate member 38 formed by bending and two roller bearings 44a and 44b pivotally supported by the first plate member 32, and these include a flat washer 40 and They are connected by a thin flat rivet 42 or the like (see FIGS. 2 and 3).

このようなリンク機構３０は、図５に示したアーム組立体３１およびローラーコンベア２７に代えて使用されるものである。
図１に示したように、リンク機構３０の第１の板材３２には、ワイヤー取付用の孔４６が１つ形成され、かつ薄平リベット４２を挿通する孔４８が２つ形成されている。なお、ワイヤー取付部材は孔４６に限定されるものではなく、他の部位あるいはドアー本体でも可能である。また、第２の板材３４には、薄平リベット４２を挿通する孔４８が２つ形成されている。 Such a link mechanism 30 is used in place of the arm assembly 31 and the roller conveyor 27 shown in FIG.
As shown in FIG. 1, the first plate member 32 of the link mechanism 30 has one wire mounting hole 46 and two holes 48 through which the thin rivets 42 are inserted. The wire attachment member is not limited to the hole 46, and may be another part or a door body. In addition, two holes 48 through which the thin flat rivets 42 are inserted are formed in the second plate member 34.

断面略Ｌ字状の第３の板材３６の一方の板部には、薄平リベット４２を挿通する孔４８が２つ形成され、他方の板部には、下部ドア２３ｂを取り付けるための孔５２が６つ形成されている。また、第４の板材３８には、薄平リベット４２を挿通する孔４８が２つ形成されている。   Two holes 48 through which the thin flat rivets 42 are inserted are formed in one plate portion of the third plate member 36 having a substantially L-shaped cross section, and a hole 52 for attaching the lower door 23b is formed in the other plate portion. 6 are formed. The fourth plate member 38 has two holes 48 through which the thin flat rivets 42 are inserted.

このようなリンク機構３０は、図２に示したように、断面略コ字状のガイドレール２４に、ローラーベアリング４４ａ、４４ｂを介して装着される。
なお、ガイドレール２４は、例えば、図４に示した箱型荷台２１の後方部に設けられた荷物の搬入、搬出のために開口２２を開閉する外折れ式ドア２３の案内部材として使用されるもので、車体フレームに取付られる。 As shown in FIG. 2, the link mechanism 30 is attached to the guide rail 24 having a substantially U-shaped cross section via roller bearings 44a and 44b.
The guide rail 24 is used, for example, as a guide member for an outward folding door 23 that opens and closes the opening 22 for loading and unloading the luggage provided in the rear part of the box-type cargo bed 21 shown in FIG. It is attached to the body frame.

そして、ガイドレール２４は床面２５より上に穴を開けずに立設される。
また、リンク機構３０の第３の板材３６に、外折れ式ドア２３の下部ドア２３ｂがボルトなどで取り付けられる。これにより、本実施例の箱型車両の外折れ式ドア構造物が構成される。 The guide rail 24 is erected without making a hole above the floor surface 25.
Further, the lower door 23b of the outer folding door 23 is attached to the third plate member 36 of the link mechanism 30 with a bolt or the like. Thereby, the outward folding door structure of the box-type vehicle of a present Example is comprised.

本実施例による外折れ式ドア２３の開閉する構成は、図２、図３に示したガイドレール２４に沿って、ワイヤー５４を介して行われる。なお、ワイヤー５４の一端部は、第１の板材３２のワイヤー取付用の孔４６に挿通されるボルト５６に係止されている。   The structure which opens and closes the external folding door 23 according to the present embodiment is performed via the wire 54 along the guide rail 24 shown in FIGS. One end of the wire 54 is locked to a bolt 56 that is inserted through the wire attachment hole 46 of the first plate member 32.

このようなワイヤー５４を図示しない操作手段で上下に操作することにより、リンク機構３０を上方に移動させたり、あるいは下方に移動させたりすることができる。したがって、これに連動して外折れ式ドア２３を閉としたり開としたりすることができる。   By operating such a wire 54 up and down with an operating means (not shown), the link mechanism 30 can be moved upward or downward. Therefore, the outer folding door 23 can be closed or opened in conjunction with this.

なお、図２は、外折れ式ドア２３により開口２２を閉としたときのリンク機構３０の姿勢であり、図３は図２の閉の姿勢から開口２２を開にするときのリンク機構３０の姿勢、すなわち下部ドア２３ｂが下方から上方に向かうときの姿勢である。   2 shows the posture of the link mechanism 30 when the opening 22 is closed by the outer folding door 23, and FIG. 3 shows the position of the link mechanism 30 when the opening 22 is opened from the closed posture of FIG. The posture, that is, the posture when the lower door 23b is directed from below to above.

図２から明らかなように、外折れ式ドア２３が開口２２を完全に閉にしたとき、下部ドア２３ｂの下端部より上方にローラーコンベア４４ｂが位置することなる。よって、本実施例では、開口２２を閉とするために、このローラーコンベア４４ｂを床面より下に位置させる必要がない。そのため、床面に穴をあけてその穴にローラーコンベア４４ｂを収納する必要がない。   As apparent from FIG. 2, when the outer folding door 23 completely closes the opening 22, the roller conveyor 44b is positioned above the lower end of the lower door 23b. Therefore, in this embodiment, in order to close the opening 22, it is not necessary to position the roller conveyor 44b below the floor surface. Therefore, it is not necessary to make a hole in the floor and store the roller conveyor 44b in the hole.

このように本実施例では、床面にローラーコンベア４４ｂを埋め込むための穴を設ける必要がないので、煩雑な作業が不要であるばかりでなく床下には車両独自の補強部材やシャーシフレーム等があり、本来このドアーを取り付けることができなかった車両にも設けることができる。   As described above, in this embodiment, since it is not necessary to provide holes for embedding the roller conveyor 44b on the floor surface, not only complicated work is required, but also a vehicle-specific reinforcing member, chassis frame, and the like are provided under the floor. It can also be provided on vehicles that were originally unable to be fitted with this door.

以上、本発明の好ましい実施例について説明したが、本発明は、これに限定されない。
例えば、上記実施例では、箱型荷台２１の後部側の開口２２に設置される外折れ式ドア構造物について説明したが、本発明はこれに限定されず、例えば、箱型荷台２１の側面に設けられる開口にも適用することができる。 As mentioned above, although the preferable Example of this invention was described, this invention is not limited to this.
For example, in the said Example, although the outer folding type door structure installed in the opening 22 of the rear part side of the box-type loading platform 21 was demonstrated, this invention is not limited to this, For example, on the side surface of the box-type loading platform 21 The present invention can also be applied to the opening provided.

また、上記実施例では、リンク機構３０が第１の板材３２、第２の板材３４、第３の板材３６、第４の板材３８、２つのローラーベアリング４４ａ、４４ｂなどから構成されているが、リンク機構は、これに限定されるものでなく、他の構成を採用することができる。   Moreover, in the said Example, although the link mechanism 30 is comprised from the 1st board | plate material 32, the 2nd board | plate material 34, the 3rd board | plate material 36, the 4th board | plate material 38, two roller bearings 44a and 44b, The link mechanism is not limited to this, and other configurations can be adopted.
