Description

本発明は、荷受台側がスライド部材を通じてスライドレールに沿って荷台下方の格納位置と荷台後方の作業位置との間で前後にスライド可能に構成され、荷受台を前後に少なくとも２つに折り畳んだ状態で格納位置に格納する格納式荷受台昇降装置を備えた車両に関するものである。   The present invention is configured such that the cradle side is configured to be slidable back and forth between a retracted position below the cradle and a work position behind the cradle along the slide rail through the slide member, and the cradle is folded at least in the front and back The present invention relates to a vehicle equipped with a retractable load receiving table lifting device that is stored in the storage position.

従来、トラック等の比較的大型の特殊車両においては、当該車両への突入事故を防止して走行時における安全性を確保する観点から車両の後部に規定に応じた大きさの反射器を取付けることが義務付けられている（例えば、特許文献１参照。）。   Conventionally, in a relatively large special vehicle such as a truck, a reflector of a size according to the regulations is attached to the rear part of the vehicle from the viewpoint of preventing a rush accident into the vehicle and ensuring safety during traveling. (For example, refer to Patent Document 1).

ところで上記特殊車両に属するものとして「格納式荷受台昇降装置を備えた車両」があり、この車両にも反射器の取付けが義務付けられている。   By the way, as a vehicle belonging to the above-mentioned special vehicle, there is a “vehicle equipped with a retractable cargo cradle lifting device”, and this vehicle is also required to be attached with a reflector.

具体的には、格納式荷受台昇降装置を備えた車両として、例えば特許文献２に示すように、車両の荷台にリンク機構を介して荷受台が昇降手段により昇降自在に設けられるとともに、該リンク機構及び昇降手段を含む荷受台側がスライド部材を通じてスライドレールに沿って上記荷台下方の格納位置と荷台後方の作業位置との間で前後にスライド可能に構成され、上記荷受台が前後に少なくとも２つに折り畳まれた状態で格納位置に格納されるものが提供されている。   Specifically, as a vehicle equipped with a retractable load receiving device elevating device, for example, as shown in Patent Document 2, a load receiving device is provided on a vehicle load device via a link mechanism so as to be movable up and down by an elevating means. The load receiving platform side including the mechanism and the lifting / lowering means is configured to be slidable back and forth between the storage position below the loading platform and the working position behind the loading platform along the slide rail through the slide member. What is stored in the storage position in the folded state is provided.

そして、この場合に反射器は、例えば荷台の後部に設けられた開閉扉の適所や、または折り畳んだ荷受台の後端面に取付けるようにしていた。
実公平７−９７０１号公報 特開２００５−２３８９８２号公報 In this case, the reflector is attached to, for example, an appropriate position of an opening / closing door provided at the rear portion of the loading platform or a rear end surface of the folded loading platform.
No. 7-9701 Japanese Patent Application Laid-Open No. 2005-233892

しかしながら、上記従来のものでは以下のような不具合があった。   However, the above conventional devices have the following problems.

まず、反射器を荷台の開閉扉に取付ける場合では、この開閉扉に社名等のロゴや広告などを描くために反射器の取付けが規制されたり、反射器によってロゴや広告の美観を悪くするという問題があった。また、開閉扉を開くと後方から見て反射器が隠れてしまって機能しなくなるという問題もあった。   First, when attaching a reflector to the door of a cargo bed, the reflector is restricted to draw a logo or advertisement for the company name, etc. on the door, or the reflector makes the logo or advertisement worse. There was a problem. In addition, when the open / close door is opened, there is also a problem that the reflector is hidden from view when viewed from the rear and does not function.

さらに、反射器を折り畳んだ荷受台の後端面に取付ける場合には、当該後端面の上下厚みが所定大きさの反射器を取付けることができるだけの厚みがあれば問題はないものの、この後端面の厚みが薄くなると反射器を取付けるだけのスペースを確保することができないという問題があった。これは、傾斜地などで格納した荷受台等が地面に接触しないように荷受台の地上高さを高く確保するために、折り畳んだ荷受台の上下厚みを薄くするのが主流になっており、このために上述した問題が生じることになる。   Furthermore, when attaching the reflector to the rear end surface of the folded load receiving platform, there is no problem as long as the rear end surface has a thickness sufficient to attach a reflector having a predetermined size. When the thickness is reduced, there is a problem that it is not possible to secure a space for mounting the reflector. The mainstream of this is to reduce the vertical thickness of the folded cradle in order to ensure that the cradle that is stored on sloping ground etc. does not touch the ground. For this reason, the above-described problem occurs.

本発明は、上記問題点に鑑みてなされたもので、その目的とするところは、折り畳んだ荷受台の後端面の上下厚みを薄くした場合でも、この後端面に所定大きさの反射器を良好な状態で取付けることができる格納式荷受台昇降装置を備えた車両を提供することにある。   The present invention has been made in view of the above problems, and the object of the present invention is to provide a reflector having a predetermined size on the rear end surface even when the vertical thickness of the rear end surface of the folded load receiving base is reduced. An object of the present invention is to provide a vehicle equipped with a retractable load receiving device lifting device that can be mounted in a simple state.

スライド部材３は、前記車体枠１１の後端部に前後方向に配設されたスライドレール１２に沿って前後方向にスライド自在に設けられている。   The slide member 3 is slidable in the front-rear direction along the slide rail 12 disposed in the front-rear direction at the rear end of the vehicle body frame 11.

具体的には、スライドレール１２はＩ形鋼からなり、その途中のウエブを垂直にして配置され、このスライドレール１２にスライド部材３が図示しないスライド機構を介してスライド自在に設けられている。スライド機構としては、例えばスライドレール１２の上下フランジを上下から挟んだ状態で摺接するスライドパッドと、スライドレール１２のウエブの外側面をスライド方向に転動するローラなどで構成されている。   Specifically, the slide rail 12 is made of I-shaped steel, and is arranged with the web in the middle thereof being vertical, and the slide member 3 is slidably provided on the slide rail 12 via a slide mechanism (not shown). The slide mechanism includes, for example, a slide pad that is in sliding contact with the upper and lower flanges of the slide rail 12 sandwiched from above and below, a roller that rolls the outer surface of the web of the slide rail 12 in the slide direction, and the like.

前記リンク機構４は、下方リンク４１と、上方リンク４２とで構成されている。下方リンク４１及び上方リンク４２の基端部は、前記スライド部材３側に回動自在に枢支されるとともに、スライド部材３側と上方リンク４２の途中部に連結された昇降手段としてのリフトシリンダ４３により当該上方リンク４２が上下に回動自在に構成されている。   The link mechanism 4 includes a lower link 41 and an upper link 42. The base ends of the lower link 41 and the upper link 42 are pivotally supported on the slide member 3 side, and are lift cylinders as lifting means connected to the slide member 3 side and the middle part of the upper link 42. 43, the upper link 42 is configured to be rotatable up and down.

上述したスライドレール１２、スライド部材３、リンク機構４、リフトシリンダ４３の各部材は車体枠１１の両側に左右一対設けられており、左右のスライド部材３は同調してスライドレール１２をスライドするように連結メンバーによって連結されている。   A pair of left and right slide rails 12, slide member 3, link mechanism 4, and lift cylinder 43 described above are provided on both sides of the vehicle body frame 11, so that the left and right slide members 3 slide on the slide rail 12 in synchronization. Are linked to by a linking member.

前記荷受台５は、先端側部材５１と基端側部材５２とを備えており、これら先端側部材５１と基端側部材５２とはヒンジ５３（図４参照）によって該先端側部材５１が基端側部材５２の表面側に２つ折り自在になされている。   The load receiving platform 5 includes a distal end side member 51 and a proximal end side member 52. The distal end side member 51 and the proximal end side member 52 are based on a hinge 53 (see FIG. 4). The end member 52 can be folded in two on the surface side.

上記ヒンジ５３は、両端部に二つのヒンジピン５３ａ、５３ｂを備えたもので、ヒンジピン５３ａが先端側部材５１の基端に、ヒンジピン５３ｂが基端側部材５２の基端に連結されている。そして、このヒンジ５３により荷受台５を図３に示す折り畳んだ状態から展開する際には、まずヒンジピン５３ｂを中心にしてヒンジ５３が回動して先端側部材５１が図５に二点鎖線で示すように垂直に起立し、続いて先端側部材５１がヒンジピン５３ａを中心に回動することで、基端側部材５２と先端側部材５１とが同一水平面上に配置され、また上述と逆の動作によって先端側部材５１が基端側部材５２上に折り畳まれる。   The hinge 53 includes two hinge pins 53 a and 53 b at both ends. The hinge pin 53 a is connected to the proximal end of the distal end side member 51, and the hinge pin 53 b is connected to the proximal end of the proximal end side member 52. When the load receiving platform 5 is unfolded by the hinge 53 from the folded state shown in FIG. 3, first, the hinge 53 is rotated around the hinge pin 53b, and the tip side member 51 is shown by a two-dot chain line in FIG. As shown in the figure, the proximal end member 51 and the distal end side member 51 are arranged on the same horizontal plane by the distal end side member 51 pivoting about the hinge pin 53a, and the reverse of the above. By operation, the distal end side member 51 is folded on the proximal end side member 52.

基端側部材５２の基端部左右両側には、その上部に前記左右の上方リンク４２の先端部が枢支されるとともに、その下部に前記左右の下方リンク４１の先端部が枢支されている。   On the left and right sides of the base end portion of the base end side member 52, the top ends of the left and right upper links 42 are pivotally supported at the top thereof, and the tip portions of the left and right lower links 41 are pivotally supported at the bottom thereof. Yes.

また、先端側部材５１の先端は、荷受台５が地上に達した際に傾動して地上に段差なく接地するように形成されている。   Further, the tip of the tip side member 51 is formed so as to tilt when the load receiving platform 5 reaches the ground and to be grounded to the ground without a step.

このように構成された格納式荷受台昇降装置２は、荷台１側と荷受台５側とに連結された図示しない伸縮シリンダの伸縮作動により、荷受台５を折り畳んだ状態で図１に示すような左右のスライド部材３をスライドレール１２の前端部にスライドさせて格納する格納位置と、スライド部材３をスライドレール１２の後端部にスライドさせた作業位置とに配置でき、作業位置において折り畳んだ荷受台５を展開し、この展開状態で荷受台５を地上と荷台１の床面との間で昇降作動させることができる。   The retractable load receiving device lifting / lowering device 2 configured as described above is shown in FIG. 1 in a state in which the load receiving stand 5 is folded by an expansion / contraction operation of an extension cylinder (not shown) connected to the load receiving side 1 and the load receiving stand 5 side. The left and right slide members 3 can be placed in the storage position where the slide member 3 is slid to the front end portion of the slide rail 12 and stored, and the slide member 3 is slid to the rear end portion of the slide rail 12 and folded at the work position. The loading platform 5 is developed, and the loading platform 5 can be moved up and down between the ground and the floor surface of the loading platform 1 in this unfolded state.

ところで、このように構成された格納式荷受台昇降装置２を備えた車両には、図１及び図２に示すような本発明の主要部をなす取付ステー６が設けられており、以下、この取付ステー６について図３乃至図５を参照して具体的に説明する。   By the way, the vehicle provided with the retractable load receiving device lifting / lowering device 2 configured as described above is provided with a mounting stay 6 that forms the main part of the present invention as shown in FIGS. 1 and 2. The attachment stay 6 will be specifically described with reference to FIGS.

取付ステー６は、規格に適した所定大きさの反射器７を取付けるためのもので、折り畳んだ荷受台５の後端面、つまり折り畳んだ際の先端側部材５１及び基端側部材５２の後端面に沿って上下に配置されるように設けられている。   The mounting stay 6 is for attaching a reflector 7 having a predetermined size suitable for the standard, and is a rear end surface of the folded load receiving platform 5, that is, a rear end surface of the front end side member 51 and the base end side member 52 when folded. It is provided so that it may be arranged up and down along.

詳しくは、取付ステー６の両側の一端縁（荷受台５を折り畳んで取付ステー６が起立状態に配置された際には下端縁側）が基端側部材５２の後端面の下端縁にブラケット６２を介して支持ピン６１によって上下（前後）に回動自在に支持されている。   Specifically, one end edge on both sides of the mounting stay 6 (the lower end edge side when the load receiving stand 5 is folded and the mounting stay 6 is placed in the standing state) is the bracket 62 on the lower end edge of the rear end surface of the base end side member 52. And is supported by the support pin 61 so as to be rotatable up and down (front and rear).

また、取付ステー６の他端縁にはワイヤ６３の一端が連結され、このワイヤ６３の他端が先端側部材５１に連結されている。このワイヤ６３は、荷受台５を折り畳んだ際に起立状態に配置された取付ステー６を当該起立状態で保持するために設けられたもので、起立状態に配置された取付ステー６が後方に回動するのを阻止するように両者に張設されている。   One end of the wire 63 is connected to the other end edge of the mounting stay 6, and the other end of the wire 63 is connected to the distal end side member 51. This wire 63 is provided to hold the mounting stay 6 placed in the upright state when the load receiving platform 5 is folded, and the mounting stay 6 placed in the upright state rotates backward. It is stretched on both sides to prevent it from moving.

さらに、前記支持ピン６１と取付ステー６との間には、図４に示すようにトーションバー６５が介装されている。このトーションバー６５は、折り畳んだ荷受台５を展開する際に下方に回動する取付ステー６に対して起立方向への付勢力を付与するためのもので、一端が前記支持ピン６１に連結されるとともに、他端が取付ステー６の途中部下端に連結されており、取付ステー６の起立状態から水平状態への回動に伴ってトーションバー６５の途中部に捩れを生じさせることで、この捩れの反力によって上述した付勢力を発生させるようにしている。   Further, a torsion bar 65 is interposed between the support pin 61 and the mounting stay 6 as shown in FIG. The torsion bar 65 is used to apply a biasing force in the upright direction to the mounting stay 6 that rotates downward when the folded load receiving platform 5 is unfolded. One end of the torsion bar 65 is connected to the support pin 61. In addition, the other end is connected to the lower end of the middle part of the mounting stay 6, and twisting is caused in the middle part of the torsion bar 65 as the mounting stay 6 rotates from the standing state to the horizontal state. The urging force described above is generated by the reaction force of torsion.

このようにしてトーションバー６５を設けることによって、図５に示すように荷受台５を展開して基端側部材５２に対して先端側部材５１を同一平面上に配置したときには、取付ステー６が支持ピン６１を中心にして上方へ付勢される形で先端側部材５１の基端部下面に沿って水平状態に配置され、この状態を保持することになる。   By providing the torsion bar 65 in this way, when the load receiving platform 5 is expanded and the distal end side member 51 is arranged on the same plane with respect to the proximal end side member 52 as shown in FIG. It is arranged in a horizontal state along the lower surface of the base end portion of the distal end side member 51 so as to be biased upward around the support pin 61, and this state is maintained.

従って、取付ステー６は、図３に示すように荷受台５を折り畳んだ際にはこの折り畳んだ荷受台５の後端面に沿って起立状態に配置されるとともに、図５に示すように作業時において荷受台５を展開した際にはこの展開した荷受台５の下面に沿って水平状態に配置される。   Therefore, the mounting stay 6 is arranged in a standing state along the rear end surface of the folded load receiving stand 5 when the load receiving stand 5 is folded as shown in FIG. When the load receiving platform 5 is expanded, the horizontal position is arranged along the lower surface of the expanded load receiving platform 5.

また、取付ステー６の背面適所にはクッション材６６が設けられており、上述したように取付ステー６が起立状態に配置された場合には荷受台５（折り畳んだ基端側部材５２及び先端側部材５１）の後端面に当接するとともに、取付ステー６が水平状態に配置された場合には荷受台５の先端側部材５１の下面基端部に当接することで、衝撃等を緩和するようにしている。   Further, a cushion material 66 is provided at an appropriate position on the back surface of the mounting stay 6, and when the mounting stay 6 is arranged in an upright state as described above, the load receiving platform 5 (the folded proximal end side member 52 and the distal end side). The member 51) abuts on the rear end surface, and when the mounting stay 6 is disposed in a horizontal state, it abuts on the lower surface base end portion of the front end side member 51 of the load receiving base 5 so as to alleviate the impact or the like. ing.

次に、このように構成された格納式荷受台昇降装置２の動作について説明する。   Next, the operation of the retractable load receiving table elevating device 2 configured as described above will be described.

まず、格納式荷受台昇降装置２を図１に示すように荷台１の下方に格納した格納位置に配置した状態では、取付ステー６は折り畳んだ荷受台５の後端面に沿って起立状態に配置されている。この結果、取付ステー６に取付けた反射器７が後方に張り出すようにして配置され、これによって車両への突入事故を防止するなどの機能を良好に果たすようになっている。   First, in the state in which the retractable load receiving device lifting device 2 is disposed at the retracted position stored below the load carrier 1 as shown in FIG. 1, the mounting stay 6 is disposed in an upright state along the rear end surface of the folded load receiving stand 5. Has been. As a result, the reflector 7 attached to the attachment stay 6 is disposed so as to protrude rearward, and thus, functions such as preventing a rush accident into the vehicle are satisfactorily performed.

次に、格納式荷受台昇降装置２を格納位置から作業位置に配置するには、伸縮シリンダをそれぞれ伸長作動させる。この伸縮シリンダの伸長動作により左右のスライド部材３がスライド機構を介して左右のスライドレール１２に沿って荷台１の後端部側に移動することで、格納式荷受台昇降装置２全体が荷台１の後端部側にスライドして作業位置に配置される。   Next, in order to arrange the retractable load receiving table lifting device 2 from the retracted position to the working position, the telescopic cylinders are respectively extended. By the extension operation of the telescopic cylinder, the left and right slide members 3 are moved along the left and right slide rails 12 to the rear end side of the cargo bed 1 through the slide mechanism, whereby the entire retractable load receiving table lifting device 2 is loaded. It slides to the rear end side and is arranged at the working position.

このようにして格納式荷受台昇降装置２を作業位置に配置すると、まず、折り畳まれた荷受台５を一旦下方の地上もしくは地上付近まで降下させた後、この折り畳まれた荷受台５の先端側部材５１を後方に回動させ、当該先端側部材５１が基端側部材５２と同一水平面上になるように展開する。これにより、荷受台５はリフトシリンダ４３の伸縮動作により地上と荷台１の床面との間で昇降可能な状態になり、この昇降動作によって荷受台５を通じて地上と荷台１との間で荷物の積降ろし作業を行うことができる。   When the retractable load receiving device lifting / lowering device 2 is arranged at the work position in this way, first, the folded load receiving stand 5 is once lowered to the lower ground or near the ground, and then the front end side of the folded load receiving stand 5 The member 51 is rotated backward, and the distal end side member 51 is deployed so as to be on the same horizontal plane as the proximal end side member 52. As a result, the load receiving platform 5 can move up and down between the ground and the floor surface of the loading platform 1 by the expansion and contraction operation of the lift cylinder 43. Unloading work can be performed.

この際、取付ステー６は、先端側部材５１の基端部下面に沿って水平状態に配置され、しかもトーションバー６５よって上方へ回動する方向に付勢されているため、上述した水平状態を安定的に保持している。   At this time, the mounting stay 6 is disposed in a horizontal state along the bottom surface of the proximal end portion of the distal end side member 51 and is urged in a direction to rotate upward by the torsion bar 65. Holds stably.

次に、荷物の積降ろし作業が終了して格納式荷受台昇降装置２を格納する場合には、前述した動作と逆の動作により格納式荷受台昇降装置２を作業位置から格納位置に配置する。即ち、作業位置において、荷受台５を地上もしくは地上付近において先端側部材５１を前方に回動させて二つ折りにし、この状態で当該荷受台５を格納する所定の高さに配置した後、スライド部材３を通じてスライドレール１２に沿って荷台１の下方にスライドさせ、図１に示すように格納位置に配置する。   Next, when the loading and unloading work is completed and the retractable load receiving device lifting / lowering device 2 is stored, the retractable load receiving device lifting / lowering device 2 is arranged from the working position to the retracted position by the reverse operation to the operation described above. . That is, in the working position, the load receiving platform 5 is folded in half by rotating the front end side member 51 forward on or near the ground, and is placed at a predetermined height for storing the load receiving platform 5 in this state. It is made to slide below the loading platform 1 along the slide rail 12 through the member 3, and arrange | positions in a storage position as shown in FIG.

これにより、取付ステー６は、上述したように折り畳んだ荷受台５の後端面に沿って起立状態に配置され、当該取付ステー６に取付けた反射器７によって車両への突入事故を防止するなどの機能を良好に果たすようになっている。   As a result, the mounting stay 6 is arranged in a standing state along the rear end surface of the load receiving platform 5 folded as described above, and the reflector 7 attached to the mounting stay 6 prevents an accidental entry into the vehicle. It is designed to perform well.

このように取付ステー６を荷受台５に設け、この取付ステー６に反射器７を取付けることで、折り畳んだ荷受台５の後端面の上下厚みが薄い場合でも、この後端面に反射器７を良好な状態で取付けることができ、荷受台５の薄型化に好適に対応することができる。   Thus, by providing the mounting stay 6 on the load receiving base 5 and attaching the reflector 7 to the mounting stay 6, the reflector 7 is attached to the rear end face even when the rear end surface of the folded load receiving base 5 is thin. It can be attached in a good state, and can suitably cope with a reduction in the thickness of the load receiving tray 5.

なお、上述した実施形態は、あくまでも本発明の好適な実施態様を示すものであって、本発明はこれに限定されることなく、その範囲内において種々設計変更可能である。   Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

例えば、二つ折り自在な荷受台５に付いて説明したが、荷受台５は三つ折りなど二つ以上に折り畳むものであってもよい。   For example, although the description has been given with respect to the cradle 5 that can be folded in half, the cradle 5 may be folded in two or more, such as a trifold.

また、本実施の形態では取付ステー６が下端縁に連設した支持ピン６１を中心にして回動するものについて説明したが、取付ステー６の上端縁側を中心にして回動するようにヒンジ位置を上下逆に設けたものであってもよい。   In the present embodiment, the mounting stay 6 rotates about the support pin 61 connected to the lower end edge. However, the hinge position is set so as to rotate about the upper end edge side of the mounting stay 6. May be provided upside down.

さらに、取付ステー６は、荷受台５の折り畳み動作と展開動作に伴って反射器７を上述したように配置できるものであれば、その形状や配置状態などは特に限定されるものでない。   Further, the mounting stay 6 is not particularly limited in its shape and arrangement as long as the reflector 7 can be disposed as described above in accordance with the folding operation and the unfolding operation of the load receiving platform 5.
