Description

本発明は、荷台等を車体等に振動等を抑制しつつ支持する車両用荷台支持装置に関する。   The present invention relates to a vehicle carrier support device that supports a carrier, etc., on a vehicle body or the like while suppressing vibration or the like.

近年、精密機械などの振動に対してデリケートな物品の輸送に関し、その輸送品質の向上を図ることが望まれており、かかる観点から、車両のフレームと、荷台と、の間にスプリングやエアスプリングなどを介装したものが、特許文献１や特許文献２において提案されている。   In recent years, it has been desired to improve the transportation quality of goods sensitive to vibrations such as precision machinery. From this viewpoint, springs and air springs are provided between the vehicle frame and the loading platform. Patent Literature 1 and Patent Literature 2 have proposed that intervene.

また、特許文献３には、車両のフレームと、荷台と、の間にエアスプリングを備え、積載荷重が変化しても支持高さを一定に維持でき、かつ、ばね定数を低く維持できると共に、水平方向における位置決めも行なえるようにした制振支持装置が提案されている。   Further, in Patent Document 3, an air spring is provided between the vehicle frame and the loading platform, the support height can be kept constant even when the load is changed, and the spring constant can be kept low. There has been proposed a vibration damping support device that can perform positioning in the horizontal direction.

しかしながら、これら特許文献１〜３に記載のものは、荷台に積載される物品の輸送時における具体的な状態などが十分に考慮されておらず、輸送される物品によっては、振動の影響を受けて損傷等が生じ商品価値を低下させてしまうといったことが想定される。
また、特許文献１〜３に記載のものは、スプリング、ショックアブソーバー、ラテラルロッド、エアスプリング等の比較的複雑で高価な構成要素が必要であり、製品コストや取付工数の低減が難しく、また設置スペース等に多くの制限が課されるなどといった実情もある。 However, those described in Patent Documents 1 to 3 do not sufficiently take into account the specific state during transportation of the article loaded on the loading platform, and are affected by vibration depending on the article to be transported. As a result, damage or the like may occur and the product value may be reduced.
In addition, those described in Patent Documents 1 to 3 require relatively complicated and expensive components such as springs, shock absorbers, lateral rods, air springs, etc., and it is difficult to reduce product costs and installation man-hours. There are also actual situations such as many restrictions on space.

以下、本発明に係る実施の形態を、添付の図面を参照しつつ説明する。なお、以下で説明する実施例により、本発明が限定されるものではない。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the examples described below.

実施例１に係る車両用荷台支持構造及び装置は、図１、図２に示すように、例えば輸送用車両の車体フレーム１にマウンティング２が載置され、このマウンティング２は、ラバー要素２Ａの図１中下側と係合する下側プレート２Ｂを介して車体フレーム１に、固定用ボルト３、固定部材４等により取り付けられている。なお、マウンティング２は、例えば、図１に示したように、車両前後方向に延在される左右のそれぞれのフレーム１の車両前後方向において少なくとも２つ備えられることができる。   As shown in FIGS. 1 and 2, the vehicle carrier support structure and apparatus according to the first embodiment has a mounting 2 mounted on a body frame 1 of a transportation vehicle, for example, and this mounting 2 is a view of a rubber element 2A. 1 is attached to the vehicle body frame 1 by a fixing bolt 3, a fixing member 4, and the like via a lower plate 2B that engages with the lower side in the middle. For example, as shown in FIG. 1, at least two mountings 2 can be provided in the vehicle front-rear direction of the left and right frames 1 that extend in the vehicle front-rear direction.

前記マウンティング２の構成要素であるラバー要素（弾性要素）２Ａの図１中上側と係合する上側プレート２Ｃには、木等からなる縦根太（固定用部材）６が前記フレーム１に沿って載置され、固定部材７、固定用ボルト８等を介して、当該上側プレート２Ｃと前記縦根太６とが締結固定されている。
なお、前記縦根太６には、例えば、当該縦根太６と交差する方向に延在される金属製等の横根太（図示せず）が載置され、この横根太の上に荷台（図示せず）が載置されるようになっている。 A vertical joist (fixing member) 6 made of wood or the like is placed along the frame 1 on the upper plate 2C that engages with the upper side in FIG. 1 of the rubber element (elastic element) 2A that is a component of the mounting 2. The upper plate 2C and the vertical joist 6 are fastened and fixed via a fixing member 7, fixing bolts 8 and the like.
The vertical joist 6 is mounted with a horizontal joist (not shown) made of metal or the like extending in a direction intersecting the vertical joist 6, and a loading platform (not shown) is placed on the horizontal joist. Z)) is placed.

ここで、図２に示すようなマウンティング２を備えた実施例１に係る車両用荷台支持構造及び装置によれば、簡単かつ安価な構成で、取り付けなども容易でありながら、荷台等を車体等に振動等を抑制しつつ支持することができる車両用荷台支持構造及び装置を提供することができる。   Here, according to the vehicle carrier support structure and apparatus according to the first embodiment provided with the mounting 2 as shown in FIG. 2, the carrier and the like can be attached to the vehicle body or the like with a simple and inexpensive configuration and easy installation. In addition, it is possible to provide a vehicle carrier support structure and device that can be supported while suppressing vibration and the like.

なお、本実施例のような構成とすれば、車両用荷台支持装置をフレーム１に取り付けるためにフレーム１に対して特別な加工等が必要ないため、当該車両用荷台支持装置の要求されない車両と共通のフレーム１を用いることができ、以って製品コストの低減等を図ることができる。   In addition, if it is set as a structure like a present Example, since the special process etc. are not required with respect to the flame | frame 1 in order to attach a vehicle carrier support apparatus to the flame | frame 1, the said vehicle carrier support apparatus is not required. The common frame 1 can be used, so that the product cost can be reduced.

また、例えば車両の出荷後に荷台（所謂平ボディー、ウィングタイプ、アルミバン、保冷車等の荷台など）を要求に応じて取り付けたり変更することも容易であり、ユーザーフレンドリーな車両用荷台支持装置を提供することができるものである。   In addition, for example, it is easy to attach and change the loading platform (so-called flat body, wing type, aluminum van, cold storage vehicle, etc.) after shipment of the vehicle as required, providing a user-friendly vehicle loading platform support device Is something that can be done.

例えば、車両衝突や横転などの不測の事態が生じた場合などを想定すると、縦根太６（すなわち、荷台）と、フレーム１と、を引き離す方向に大きな力が作用する場合も想定され、このような力が作用した場合、実施例１のような構成においては、ラバー要素２Ａの強度及びラバー要素２Ａと下側プレート２Ｂ或いは上側プレート２Ｃとの加硫接着強度に依存することになるため、縦根太６（荷台）のフレーム１からの離脱を防止できる強度を確保することが難しい場合も想定される。   For example, assuming an unexpected situation such as a vehicle collision or rollover, a case where a large force acts in the direction of separating the vertical joist 6 (that is, the loading platform) and the frame 1 is assumed. When a strong force is applied, the configuration as in the first embodiment depends on the strength of the rubber element 2A and the vulcanization adhesion strength between the rubber element 2A and the lower plate 2B or the upper plate 2C. There may be a case where it is difficult to secure a strength capable of preventing the joist 6 (loading platform) from being detached from the frame 1.

そこで、実施例２では、縦根太６（荷台）のフレーム１からの離脱を確実に防止できる離脱防止機構を備えた車両用荷台支持構造及び装置を提供する。   Therefore, in the second embodiment, there is provided a vehicle carrier support structure and device provided with a separation preventing mechanism that can reliably prevent the vertical joists 6 (cargo) from detaching from the frame 1.

すなわち、実施例２では、図３（Ａ）、図３（Ｂ）、及び図４に示すように、固定用ボルト３の上端に延長部分３０を設け、当該延長部分３０の上端付近に螺子部３１を形成すると共に、螺子部３１と延長部分３０との間には径方向における所定の段差３２が設けられている。   That is, in the second embodiment, as shown in FIGS. 3A, 3B, and 4, an extension portion 30 is provided at the upper end of the fixing bolt 3, and a screw portion is provided near the upper end of the extension portion 30. 31 and a predetermined step 32 in the radial direction is provided between the screw portion 31 and the extended portion 30.

そして、図３（Ａ）、図３（Ｂ）、及び図４に示されるように、フレーム１を車幅方向において挟んで両側に配設される一対の固定用ボルト３延いては螺子部３１には、縦根太６を跨ぐようにして離脱防止部材３３が挿入され、当該離脱防止部材３３は前記段差３２に突き当てられて、ナット（例えばダブルナット）３４により締結固定されるといった離脱防止機構が備えられている。   Then, as shown in FIGS. 3A, 3B, and 4, a pair of fixing bolts 3 extending on both sides of the frame 1 in the vehicle width direction and extending to a screw portion 31 are provided. The detachment preventing member 33 is inserted so as to straddle the vertical joists 6, and the detachment preventing member 33 is abutted against the step 32 and is fastened and fixed by a nut (for example, a double nut) 34. Is provided.

なお、図３（Ｂ）に示されるように、離脱防止部材３３の下面と、縦根太６の上面と、の間には、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されており、また、延長部分３０と、縦根太６の側面と、の間にも、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されている。   As shown in FIG. 3B, a predetermined vibration that can be allowed in the normal use range by the rubber element 2A is provided between the lower surface of the separation preventing member 33 and the upper surface of the vertical joist 6. And a predetermined gap that allows vibration in the normal use range by the rubber element 2A is left between the extended portion 30 and the side surface of the vertical joist 6. Yes.

従って、実施例２によれば、ラバー要素２Ａにより荷台を弾性的に支持するといった本発明の特徴を阻害しない態様としながら、縦根太６（荷台）がフレーム１から引き離されようとした場合には、前記離脱防止部材３３がこれを阻止するように機能するため、縦根太６（荷台）のフレーム１からの離脱を確実に防止することができることになる。   Therefore, according to the second embodiment, when the vertical joist 6 (loading platform) is to be separated from the frame 1 while maintaining the aspect of the present invention such that the loading platform is elastically supported by the rubber element 2A. Since the separation preventing member 33 functions to prevent this, the separation of the vertical joists 6 (loading platform) from the frame 1 can be reliably prevented.

なお、一対の固定用ボルト３は、図５に示すような、一対の固定用ボルト３５、螺子部３６、締結固定用ダブルナット３６などを含む構成のものに代替可能である。   The pair of fixing bolts 3 can be replaced with a configuration including a pair of fixing bolts 35, a screw portion 36, a fastening and fixing double nut 36, and the like as shown in FIG.

図５に示した固定用ボルト３５を用いることは、部品点数が少なく組み立て易いなどの利点があるが、固定用ボルト３５はボルト頭部から螺子部３１や段差３２までの途中に螺子部３６が設けられる構成であるため、比較的特殊なものであり、入手性やコスト面などで改善すべき点もある。   The use of the fixing bolt 35 shown in FIG. 5 has the advantage that the number of parts is small and the assembly is easy, but the fixing bolt 35 has a screw portion 36 in the middle from the bolt head to the screw portion 31 or the step 32. Since the configuration is provided, the configuration is relatively special, and there are also points to be improved in terms of availability and cost.

そこで、実施例３では、図６、図７に示すような離脱防止機構を採用する。
実施例３では、図６、図７に示したように、比較的入手容易な固定用ボルト４０を採用し、その先端付近の螺子部４１にナット４２を螺合して、下側プレート２Ｂと固定部材４とでフレーム１を上下方向から挟むように締結固定する。 Therefore, in the third embodiment, a separation preventing mechanism as shown in FIGS. 6 and 7 is employed.
In the third embodiment, as shown in FIGS. 6 and 7, the fixing bolt 40, which is relatively easy to obtain, is adopted, and a nut 42 is screwed into the screw portion 41 near the tip thereof, so that the lower plate 2B and The frame 1 is fastened and fixed with the fixing member 4 so as to be sandwiched from above and below.

次に、内周に螺子が切られたパイプ状要素４３を螺子部４１に螺合させ、内側ナット４２に当接させるまでねじ込む。このとき、ナット４２が緩み方向に回転しないように、当該パイプ状要素４３を所謂ダブルナット（緩み止めナット）として機能させることができる。
なお、パイプ状要素４３の外周は、六角形状であったり、或いは一部に二面幅を有する部分が形成されており、スパナなどの工具を用いてパイプ状要素４３を締結することができるようになっている。 Next, the pipe-shaped element 43 having a threaded inner periphery is screwed into the screw portion 41 and screwed in until it comes into contact with the inner nut 42. At this time, the pipe-shaped element 43 can function as a so-called double nut (a locking nut) so that the nut 42 does not rotate in the loosening direction.
In addition, the outer periphery of the pipe-shaped element 43 is hexagonal, or a part having a two-sided width is formed in part, so that the pipe-shaped element 43 can be fastened using a tool such as a spanner. It has become.

その後、パイプ状要素４３の上端に、図６に示すような離脱防止部材３３を載置し、ボルト４４を介して、パイプ状要素４３に離脱防止部材３３を締結固定する。   Thereafter, a separation preventing member 33 as shown in FIG. 6 is placed on the upper end of the pipe-shaped element 43, and the separation preventing member 33 is fastened and fixed to the pipe-shaped element 43 via the bolt 44.

なお、図６（Ｂ）に示したように、離脱防止部材３３の下面と、縦根太６の上面と、の間には、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されており、また、パイプ状要素４３と、縦根太６の側面と、の間にも、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されている。   Note that, as shown in FIG. 6B, the rubber element 2A can be allowed to vibrate in the normal use range between the lower surface of the separation preventing member 33 and the upper surface of the vertical joist 6. In addition, a predetermined gap that allows vibration in the normal use range by the rubber element 2A is left between the pipe-shaped element 43 and the side surface of the vertical joist 6 as well. ing.

従って、実施例３によれば、入手容易で低コストな構成で、ラバー要素２Ａにより荷台を弾性的に支持するといった本発明の特徴を阻害しない態様としながら、縦根太６（荷台）がフレーム１から引き離されようとした場合には、前記離脱防止部材３３がこれを阻止するように機能するため、縦根太６（荷台）のフレーム１からの離脱を確実に防止することができることになる。   Therefore, according to the third embodiment, the vertical joist 6 (loading platform) is the frame 1 while maintaining the aspect of the present invention such that the loading platform is elastically supported by the rubber element 2A with an easily available and low-cost configuration. When the detachment preventing member 33 is to be separated from the frame 1, the detachment preventing member 33 functions to prevent this, so that the vertical joist 6 (loading platform) can be reliably prevented from detaching from the frame 1.

実施例４に係る車両用荷台支持構造及び装置の離脱防止機構は、図８（Ａ）、図８（Ｂ）に示すように、下側プレート２Ｂの車幅方向両端から立ち上がり縦根太６の側面を覆うように上方に延在される一対の垂直部材５０と、縦根太６を跨ぎ前記一対の垂直部材５０間に渡して配設される離脱防止部材５１と、を含んで構成され、一対の垂直部材５０と離脱防止部材５１とをボルト・ナット等の締結要素５２にて締結固定するようになっている。   As shown in FIGS. 8 (A) and 8 (B), the vehicle carrier support structure and the device detachment prevention mechanism according to the fourth embodiment rise from both ends in the vehicle width direction of the lower plate 2B and the side surfaces of the vertical joists 6 A pair of vertical members 50 extending upward so as to cover and a detachment preventing member 51 disposed across the pair of vertical members 50 across the vertical joists 6, The vertical member 50 and the separation preventing member 51 are fastened and fixed by fastening elements 52 such as bolts and nuts.

或いは、図９（Ａ）、図９（Ｂ）に示すように、下側プレート２Ｂをフレーム１に対して締結固定する固定用ボルト３に共締めされるフランジ部６１と、当該フランジ部６１から立ち上がり縦根太６の側面を覆うように上方に延在される一対の垂直部材６２と、当該一対の垂直部材６２から延伸され縦根太６を跨ぐように連結された連結部６３と、を備えた離脱防止部材６０を含んで構成される。   Alternatively, as shown in FIGS. 9A and 9B, a flange portion 61 that is fastened together with a fixing bolt 3 that fastens and fixes the lower plate 2 </ b> B to the frame 1, and the flange portion 61. A pair of vertical members 62 extending upward to cover the side surfaces of the rising vertical joists 6, and a connecting portion 63 extending from the pair of vertical members 62 and connected so as to straddle the vertical joists 6. The detachment preventing member 60 is included.

更に、図１０（Ａ）、図１０（Ｂ）に示すように、車幅方向内側に開口箇所があるようなフック形状の離脱防止部材６５を、ボルト・ナット等の締結要素６６によりフレーム１に略一体的に取り付ける構成とすることも可能である。離脱防止部材６５は車幅方向において一対で配設されるため、車幅方向の一方への離脱防止は対応する一方の離脱防止部材６５により達成可能であり、車幅方向の他方への離脱防止は対応する他方の離脱防止部材６５により達成可能であるため、上述したようなフック形状の採用も可能である。   Further, as shown in FIGS. 10A and 10B, a hook-shaped separation preventing member 65 having an opening in the vehicle width direction is attached to the frame 1 by fastening elements 66 such as bolts and nuts. It can also be set as the structure attached substantially integrally. Since the separation preventing members 65 are disposed in a pair in the vehicle width direction, prevention of separation in one of the vehicle width directions can be achieved by the corresponding one separation prevention member 65, and prevention of separation in the other in the vehicle width direction. Can be achieved by the corresponding other detachment preventing member 65, so that the hook shape as described above can also be adopted.

なお、図８（Ｂ）、図９（Ｂ）、図１０（Ｂ）に示したように、離脱防止部材５１（或いは連結部材６３、離脱防止部材６５）の下面と、縦根太６の上面と、の間には、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されており、また、垂直部材５０（或いは垂直部材６２、離脱防止部材６５）と、縦根太６の側面と、の間にも、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間が残されている。   8B, FIG. 9B, and FIG. 10B, the lower surface of the separation preventing member 51 (or the connecting member 63 and the separation preventing member 65), and the upper surface of the vertical joist 6 Between the vertical member 50 (or the vertical member 62 and the detachment preventing member 65) and the vertical member 50A, the predetermined gap that allows the vibration in the normal use range by the rubber element 2A is left. Also between the side surface of the joist 6 is left a predetermined gap that can allow vibration in the normal use range by the rubber element 2A.

従って、実施例４によれば、簡単かつ安価な構成で、ラバー要素２Ａにより荷台を弾性的に支持するといった本発明の特徴を阻害しない態様としながら、縦根太６（荷台）がフレーム１から引き離されようとした場合には、離脱防止部材がこれを阻止するように機能するため、縦根太６（荷台）のフレーム１からの離脱を確実に防止することができることになる。   Therefore, according to the fourth embodiment, the vertical joist 6 (loading platform) is separated from the frame 1 while maintaining the aspect of the present invention such that the loading platform is elastically supported by the rubber element 2A with a simple and inexpensive configuration. In such a case, since the separation preventing member functions to prevent this, it is possible to reliably prevent the vertical joist 6 (loading platform) from detaching from the frame 1.

実施例５に係る車両用荷台支持構造及び装置の離脱防止機構においては、図１１（Ａ）、図１１（Ｂ）に示すように、下側プレート２Ｂとフレーム１とを締結固定する一対の固定用ボルト３の軸部３Ａに環状部材７１が挿入され、各環状部材７１に連結要素７２が取り付けられ、これら環状部材７１と連結要素７２とにより離脱防止部材７０が構成される。   In the vehicle carrier support structure and the device separation preventing mechanism according to the fifth embodiment, as shown in FIGS. 11A and 11B, a pair of fixings that fasten and fix the lower plate 2B and the frame 1 together. An annular member 71 is inserted into the shaft portion 3A of the bolt 3 for use, and a connecting element 72 is attached to each annular member 71. The annular member 71 and the connecting element 72 constitute a separation preventing member 70.

或いは、図１２（Ａ）、図１２（Ｂ）に示すように、連結要素７２により縦根太６を掛け回し、連結要素７２の両端部に取り付けられている環状部材７１をフレーム１に締結要素７３などを介して直接的に取り付けることで、離脱防止部材７０’を構成する。   Alternatively, as shown in FIGS. 12A and 12B, the vertical joists 6 are hung by the connecting element 72, and the annular members 71 attached to both ends of the connecting element 72 are attached to the frame 1 as the fastening elements 73. The detachment preventing member 70 ′ is configured by being attached directly via the above.

すなわち、実施例５では、可撓性を有する連結要素７２により荷台側の少なくとも一部（例えば縦根太６）を掛け回す一方で、連結要素７２の両端部（環状部材７１）をフレーム１に略一体的に取り付けることで、荷台（縦根太６）がフレーム１から離脱することを防止する構成となっている。   That is, in the fifth embodiment, at least a part of the loading platform side (for example, the vertical joist 6) is hung around by the flexible connecting element 72, while both end portions (the annular member 71) of the connecting element 72 are substantially attached to the frame 1. By being attached integrally, it is the structure which prevents that a loading platform (vertical joist 6) detaches | leaves from the flame | frame 1.

前記連結要素７２は、ワイヤー、ケーブル、ロープなどとすることができ、例えば金属製やケブラーなどの樹脂製の細い繊維を撚って形成することができる。
また、連結要素７２は、チェーンなどの鎖状の連結要素とすることもできる。 The connecting element 72 can be a wire, a cable, a rope, or the like, and can be formed by twisting thin fibers made of resin such as metal or Kevlar.
Further, the connecting element 72 may be a chain-like connecting element such as a chain.

なお、図１１（Ｂ）、図１２（Ｂ）に示したように、連結要素７２と、縦根太６と、の間には、ラバー要素２Ａによる通常使用範囲での振動を許容することができる所定の隙間（遊び）が残されている。   As shown in FIGS. 11B and 12B, vibration in the normal use range by the rubber element 2A can be allowed between the connecting element 72 and the vertical joist 6. A predetermined gap (play) is left.

従って、実施例５によれば、簡単かつ安価で設置自由度の高い構成で、ラバー要素２Ａにより荷台を弾性的に支持するといった本発明の特徴を阻害しない態様としながら、縦根太６（荷台）がフレーム１から引き離されようとした場合には、離脱防止部材７０或いは７０’がこれを阻止するように機能するため、縦根太６（荷台）のフレーム１からの離脱を確実に防止することができることになる。   Therefore, according to the fifth embodiment, the vertical joist 6 (loading platform) has a configuration that is simple, inexpensive, and has a high degree of freedom of installation, and does not hinder the features of the present invention such that the loading platform is elastically supported by the rubber element 2A. Is prevented from being detached from the frame 1, the separation preventing member 70 or 70 ′ functions to prevent this, so that the vertical joist 6 (loading platform) can be reliably prevented from detaching from the frame 1. It will be possible.

なお、図１３に示すように、各実施例において、ラバー要素２Ａは、車両前後方向において少なくとも２つに分割されることができる。   As shown in FIG. 13, in each embodiment, the rubber element 2A can be divided into at least two in the vehicle front-rear direction.

ここで、ラバー要素２Ａを車両前後方向において分割すると、上側プレート２Ｃ（荷台側）は下側プレート２Ｂ（フレーム１側）に対して車両前後方向に相対変位するが、その相対変位方向に略直交するラバー要素表面の面積を２分割することで大きくすることができるため、ラバー要素の劣化等を抑制することに貢献することができる。   Here, when the rubber element 2A is divided in the vehicle front-rear direction, the upper plate 2C (loading side) is relatively displaced in the vehicle front-rear direction with respect to the lower plate 2B (frame 1 side), but substantially orthogonal to the relative displacement direction. Since the area of the surface of the rubber element to be made can be increased by dividing it into two, it is possible to contribute to suppressing deterioration of the rubber element.

以上で説明した実施の形態は、本発明を説明するための例示に過ぎず、本発明の要旨を逸脱しない範囲内において、種々変更を加え得ることは可能である。   The embodiment described above is merely an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
