Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は荷箱の内側に昇降可能なテーブルリフターを設けた貨物自動車のリフ ト装置に関する。 The present invention relates to a lifting device for a lorry having a table lifter that can move up and down inside a luggage box.

【0002】[0002]

【従来の技術】[Prior Art]

一般に、貨物自動車に装備されるテーブルリフターは荷箱の後部に平行リンク 機構を介して垂直上昇可能に設けられており、この種従来のテーブルリフターは 未使用時に荷箱の床下に折り畳んで格納するかあるいは荷箱の後面に沿わせて垂 直に配置し、一方、荷役作業時に荷箱の外部に伸展させ、このテーブルリフター を昇降させて荷役作業を行うようにしている。このため、荷役作業時にテーブル リフター上の荷物を荷箱内部に搬送する手間がかかるばかりでなく未使用時に床 下等に広いテーブルリフターの格納スペースが必要であった。そこで、このよう な問題を解決するために、同一出願人は先に荷箱の床面に荷箱後部の荷物出入口 と連続して開放する開口部を形成し、この開口部に臨ませて垂直昇降するテーブ ルリフターを設け、このテーブルリフターを昇降装置によってテーブルリフター と床面とフラットな連続面となるように荷箱の床面高さに上昇させることにより 、テーブルリフター上の荷物を直接荷箱の内部に積み込んで荷役作業の効率化を 図るとともに、荷役作業時以外はテーブルリフターを床面の一部として兼用する ことでテーブルリフターをコンパクトに格納できるように構成した貨物自動車の リフト装置を実開平2−168334号公報で提案している。 Generally, a table lifter mounted on a freight vehicle is installed in the rear part of a luggage box so that it can be vertically lifted through a parallel link mechanism, and a conventional table lifter of this kind is folded and stored under the floor of the luggage box when not in use. Alternatively, it is arranged vertically along the rear surface of the cargo box, while it is extended outside the cargo box during cargo handling work, and the table lifter is moved up and down to perform cargo handling work. For this reason, it not only takes time to transport the load on the table lifter into the cargo box during cargo handling work, but also requires a large storage space for the table lifter under the floor when not in use. Therefore, in order to solve such a problem, the same applicant first formed an opening on the floor of the packing box that opens continuously with the luggage entrance / exit at the rear of the packing box, facing the opening and vertically. A table lifter that moves up and down is provided, and the table lifter is raised by the lifting device to the height of the cargo box floor so that it is a flat continuous surface with the table lifter and the floor surface. In addition to improving the efficiency of cargo handling work by loading the inside of the truck, the table lifter is also used as a part of the floor surface except during cargo handling work so that the table lifter can be compactly stored. It is proposed in Japanese Patent Laid-Open No. 2-168334.

【考案が解決しようとする課題】[Problems to be solved by the device]

前記従来例において、荷箱の内側に設けられるテーブルリフターは構造的に荷 箱を搭載する車両側の後車軸等との衝合を避ける都合上、後車軸から車体後部ま での間に配置する必要があるが、後車軸から車体後部までの長さは保安基準等に より車両に応じて予め制限されているため、その範囲内にテーブルリフターを配 置しなければならず、このような制限によって、後車軸から車体後部まで長さを 比較的長く設定できる大型貨物自動車では幅広なテーブルリフターを用いること ができるため不都合は生じないものの、その長さに余裕のない小型貨物自動車に おいては、テーブルリフターの幅を広く設定できないために、そのテーブルリフ ターの積載能力が低く、効率的な荷役作業を行なうことができないという課題が ある。 In the above-mentioned conventional example, the table lifter provided inside the packing box is arranged between the rear axle and the rear part of the vehicle body in order to structurally avoid collision with the rear axle of the vehicle on which the packing box is mounted. However, since the length from the rear axle to the rear of the vehicle body is limited in advance according to safety standards, etc., the table lifter must be placed within that range. This makes it possible to use a wide table lifter for a large freight vehicle whose length can be set relatively long from the rear axle to the rear part of the vehicle body, but this does not cause any inconvenience, but for a small freight vehicle that cannot afford that length. However, since the width of the table lifter cannot be set wide, there is a problem that the loading capacity of the table lifter is low and efficient cargo handling work cannot be performed.

【0004】 そこで本考案は、このような課題に基づいて成されたものあり、車体側との制 限によって積載面を広く設定できないてテーブルリフターの積載能力を高めるこ とのできる貨物自動車のリフト装置を提供することを目的とする。Therefore, the present invention has been made based on such a problem, and it is not possible to set a wide loading surface due to the limitation with the vehicle body side, so that the loading capacity of the table lifter can be improved. The purpose is to provide a device.

【0005】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、車体に設けた荷箱に荷物の出入口を形成するとともに、荷箱の床面 に前記出入口と連続して開放する開口部を形成し、この開口部に臨ませてテーブ ルリフターを荷箱の内側に設け、このテーブルリフターを昇降装置によって前記 荷箱の床面高さに昇降させる貨物自動車のリフト装置において、前記テーブルリ フターの出入口側に昇降可能なドア兼用リフターを荷箱の外部に向けて隣設し、 このドア兼用リフターを起伏させて出入口の少なくとも下端側を開閉するもので ある。 According to the present invention, a luggage box provided on a vehicle body is provided with an entrance / exit for luggage, and an opening is formed on the floor of the luggage box so as to be continuously opened with the entrance / exit, and the table lifter is exposed so as to face the opening. In a lift device for a freight vehicle that is installed inside the box and that raises and lowers this table lifter to the floor level of the packing box by a lifting device, a lifter that can be lifted to the entrance / exit side of the table lifter can also be used as a door lifter The lifter that doubles as a door is opened and closed to open and close at least the lower end side of the doorway.

【0006】[0006]

【作用】[Action]

本考案は、上記構成により、荷役時にドア兼用リフターを荷箱の外部に倒伏さ せて、このドア兼用リフターと荷箱内のテーブルリフターとによって広い載置ス ペースを形成し、一方、未使用時には、各リフターを昇降装置によって床面とフ ラットな連続面となるように荷箱の床面高さに上昇させテーブルリフターを床面 の一部として兼用するとともに、ドア兼用型リフターを起立させて出入口の少な くとも下方を閉塞して出入口の開閉扉とし兼用する。 With the above-described configuration, the present invention makes the door / lifter lie down on the outside of the cargo box during loading and unloading, and the door / lifter and the table lifter in the cargo box form a wide mounting space, while not using it. At times, each lifter is lifted to the floor level of the packing box by a lifting device so that it becomes a flat continuous surface with the floor, and the table lifter is also used as a part of the floor surface, and the lifter that also serves as a door is raised. At least the lower part of the entrance / exit is closed to double as the opening / closing door of the entrance / exit.

【実施例】【Example】

以下本考案の実施例を添付図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.

【0008】 図1乃至図6は本考案の一実施例を示し、貨物自動車1のシャーシフレーム2 上にアルミバン型の荷箱3を固定し、この荷箱3の後面に荷物の出入口4を形成 している。この出入口4の内面両側部には下端部分を除いて凹溝状の案内溝5Aが 相対向して設けられ、この案内レール5Aに沿って移動するシャッター扉5によっ て前記出入口3の上部を開閉し、その出入口4の下部は後述するドア兼用型のリ フターで独立して開閉する。この荷箱3の床面3Aの後方側には前記出入口4と連 続して開放される開口部6を形成し、この開口部6に臨ませて昇降装置によって 昇降するテーブルリフター7を荷箱3の内側に配設している。このテーブルリフ ター7は前記開口部6とほぼ同形同大に形成されるとともに、その出入口4側に はテーブルリフター7と独立して昇降するドア兼用リフター8が荷箱3の外方に 向けて隣設されている。テーブルリフター7とドア兼用リフター8の各両側部に は各リフター7,8を支持する左右一対の支柱9,10がこれらの隣設端部に近接 して立設され、そのドア兼用リフター8側の支柱10の下端部はL字状に屈曲形成 され、その屈曲部10A にドア兼用リフター8の基端部が図示しないストッパー部 材によって水平に保持されて起伏自在に枢着されいる。また、荷箱3内面の前記 案内溝5A下部はドア兼用リフター8と当接して戸当りとなるストッパー8Aが荷箱 3の下端部まで縦設されるとともに、このストッパー8Aと案内レール5Aの内側に は、前記各支柱9,10を案内する平断面コ字状のガイドレール11,11A を相対向 して形成し、このガイドレール11,11A 内に各支柱9,10に沿って転動する複数 のガイドローラ12を遊転可能に軸支するとともに、各ガイドレール11,11A の下 部にそれぞれ左右一対の案内凹部13,13A を前記シャーシフレーム2の内側に延 設している。前記各リフター7の昇降装置は各々独立した油圧シリンダー14,14 A によって構成されており、この各油圧シリンダー14,14A を前記各ガイドレー ル11,11A 内上部に配設し、そのピストンロッドを前記各支柱9,10のにそれぞ れ連結して各リフター7,8を吊設することにより、各リフター7,8は各油圧 シリンダー14,14A の作動によって地面と床面3Aとの間を昇降する。この場合、 テーブルリフター7を床面3A高さに上昇するとテーブルリフター7の端縁が前記 開口部6の周縁に設けた保持枠15に当接し、このテーブルリフター7と保持枠15 との突き当てによって車両走行時のテーブルリフター7の浮き上りを抑えて、ガ タツキを防止するようにしている。そして、荷役時に前記ドア兼用リフター8を 荷箱3の外方に倒起させてこのドア兼用リフター8と前記テーブルリフター7と によって連続するフラットな載置面を形成し、一方、荷役時以外はテーブルリフ ター7を床面3A高さに上昇させてドア兼用リフター8を起伏させて出入口4の下 部を開閉することにより、ドア兼用リフター8を開閉扉として使用している。こ の場合、ドア兼用リフター8で出入口4を閉塞する際には、このドア兼用リフタ ー8は荷箱3に設けたストッパー8Aによって位置規制され、荷箱3の後面に設け た掛止金具21によってロックされる。また、上昇したテーブルリフター7は前記 シャーシフレーム2の内面に設けたロック機構Aによって支持される。このロッ ク機構Aは前記テーブルリフター7の前後両側部に突設され、その下面に傾斜面 16A を有する楔形のロック爪16と、前記案内凹部12の前方に位置してシャーシフ レーム2の内面に固定されたロック用シリンダー17と、このロック用シリンダー 17にガイド板18を介して取り付けられるとともに前記ロック爪16の傾斜面16A と 同傾斜の傾斜面19A を上面に形成するストッパー爪19と、前記シャーシフレーム 2の内面に固着された前記ガイド板18の案内枠20とで構成され、前記ロック用シ リンダー17の伸縮によって、ガイド板18が案内枠20に沿ってスライドし、これに より、ストッパー爪19とロック爪16との係合並びに係合解除が成される。なお、 前記ドア兼用リフター8を荷箱3の外部に倒伏させて荷役作業を行なう際、その 下降時にドア兼用リフター8への台車等の乗り入れが容易となるようにその後側 端部には接地面との段差を無くす傾斜面8Bが形成されている。1 to 6 show an embodiment of the present invention, in which an aluminum van type luggage box 3 is fixed on a chassis frame 2 of a freight vehicle 1, and a luggage entrance / exit 4 is formed on a rear surface of the luggage box 3. is doing. On both sides of the inner surface of the entrance / exit 4, a guide groove 5A in the form of a concave groove is provided opposite to each other except for the lower end portion, and the upper part of the entrance / exit 3 is moved by the shutter door 5 moving along the guide rail 5A. It is opened and closed, and the lower part of the entrance / exit 4 is independently opened / closed by a later-described door-type lifter. An opening 6 is formed on the rear side of the floor 3A of the luggage box 3 and is open to the doorway 4, and a table lifter 7 facing the opening 6 and moved up and down by a lifting device is placed in the luggage box. It is arranged inside 3. The table lifter 7 is formed to have substantially the same shape and size as the opening 6, and a door / lifter 8 that moves up and down independently of the table lifter 7 is provided on the entrance / exit 4 side of the cargo box 3 toward the outside. Are adjacent to each other. On both sides of the table lifter 7 and the door / lifter 8, a pair of left and right columns 9 and 10 supporting the lifters 7 and 8 are erected upright in proximity to their adjacent ends, and the door / lifter 8 side. The lower end of the column 10 is bent into an L shape, and the base end of the door / lifter 8 is horizontally held by a stopper member (not shown) and rotatably attached to the bent portion 10A. In addition, a stopper 8A that abuts against the door / lifter 8 at the lower part of the guide groove 5A on the inner surface of the packing box 3 is provided vertically to the lower end of the packing box 3 and inside the stopper 8A and the guide rail 5A. The guide rails 11 and 11A having a U-shaped cross section for guiding the columns 9 and 10 are formed to face each other, and roll along the columns 9 and 10 in the guide rails 11 and 11A. A plurality of guide rollers 12 are rotatably supported, and a pair of left and right guide recesses 13 and 13A are respectively provided under the guide rails 11 and 11A so as to extend inside the chassis frame 2. The lifting device for each lifter 7 is composed of independent hydraulic cylinders 14 and 14A, and these hydraulic cylinders 14 and 14A are disposed above the inside of the guide rails 11 and 11A, and their piston rods are installed. By suspending the lifters 7 and 8 connected to the columns 9 and 10, respectively, the lifters 7 and 8 are moved between the ground and the floor 3A by the operation of the hydraulic cylinders 14 and 14A. Move up and down. In this case, when the table lifter 7 is raised to the height of the floor surface 3A, the edge of the table lifter 7 abuts on the holding frame 15 provided on the peripheral edge of the opening 6, and the table lifter 7 and the holding frame 15 are abutted against each other. This prevents the table lifter 7 from rising when the vehicle is running, and prevents rattling. When the cargo is handled, the door / lifter 8 is tilted to the outside of the packing box 3 to form a continuous flat mounting surface by the door / lifter 8 and the table lifter 7. The door lifter 8 is used as an opening / closing door by raising the table lifter 7 to the height of the floor surface 3A and raising / lowering the door lifter 8 to open / close the lower part of the entrance / exit 4. In this case, when closing the entrance / exit 4 with the door / lifter 8, the door / lifter 8 is positionally regulated by the stopper 8A provided on the luggage box 3 and the hooking metal fitting 21 provided on the rear surface of the luggage box 3 is provided. Locked by. The lifted table lifter 7 is supported by a lock mechanism A provided on the inner surface of the chassis frame 2.

An inclined surface 8B is formed so as to eliminate the step between and.

【0009】 以上のように構成される本考案の作用について説明する。The operation of the present invention configured as above will be described.

【0010】 まず、荷役作業を行なう際に、ドア兼用リフター8と掛止金具21とのロックを 解除した後、図6で示すようにシャッター扉5を上昇させ、かつ、ドア兼用リフ ター8を倒伏させて出入口4を開放する。この場合、ドア兼用リフター8の倒伏 によってドア兼用リフター8とテーブルリフター7とが連続するフラットな載置 面が形成される。この後、図2で示すようにロック用シリンダ17を前方に伸長さ せてロック爪16とストッパー爪19との係合を解除した状態で各リフター7、8昇 降用の油圧シリンダー14,14A を同期させて伸縮させ、そのピストンロッドに吊 り下げられた各リフター7、8を同時に昇降されることによって各リフター7、 8上に積に込んだ荷物を荷箱3内へ収容する。なお、図3で示すように積荷が少 ない場合には、荷箱3内のテーブルリフター7を作動させずに荷箱3の外側に配 置するドア兼用リフター8のみ独立して昇降させることも可能であり、積荷量に 応じてドア兼用リフター8とテーブルリフター7とを選択的に使用することがで きる。また、各リフター7、8の昇降時には、各リフター7,8の支柱9,10が ガイドレール11,11A と案内凹部12,12A に沿って案内され、かつ、ガイドロー ラ13によってガタ付きが抑止されて安定的に昇降する。First, when carrying out a cargo handling operation, after unlocking the door / lifter 8 and the latching metal 21, the shutter door 5 is raised as shown in FIG. 6, and the door / lifter 8 is also lifted. Lie down and open doorway 4. In this case, a flat mounting surface is formed in which the door / lifter 8 and the table lifter 7 are continuous by the fall of the door / lifter 8. After that, as shown in FIG. 2, the lock cylinder 17 is extended forward to disengage the lock claw 16 and the stopper claw 19 from each other, and the lifters 7 and 8 are hydraulic cylinders 14 and 14A for ascending and descending. Are synchronously expanded and contracted, and the lifters 7 and 8 suspended from the piston rod are simultaneously moved up and down to accommodate the loads loaded on the lifters 7 and 8 in the cargo box 3. As shown in FIG. 3, when the load is small, the table lifter 7 in the cargo box 3 may not be operated and only the door / lifter 8 arranged outside the cargo box 3 may be independently lifted. It is possible, and the door / lifter 8 and the table lifter 7 can be selectively used according to the load. When the lifters 7 and 8 are moved up and down, the columns 9 and 10 of the lifters 7 and 8 are guided along the guide rails 11 and 11A and the guide recesses 12 and 12A, and the guide roller 13 prevents rattling. It moves up and down stably.

【0011】 次に、荷役作業が終了した段階で図4で示すように各油圧シリンダー14,14A を後退させて各テーブルリフター7,8を床面3A高さに上昇させる。この場合、 一方のテーブルリフター7は保持枠15とが突き当たり、これにより、床面3Aの開 口部6が塞がれて、これを床面3Aとして兼用し、他方のドア兼用リフター8は荷 箱3に沿わせて上方に起立させて荷箱3側のストッパー10に突き当て、このドア 兼用リフター8に荷箱3の後面に設けたロック用の掛止金具21を係止して出入口 4の下部を閉塞するとともに、出入口4の上部をシャッター扉5によって閉塞し てし出入口4全面を閉じる。そして、図4で示すように前方に伸したロック用シ リンダー17を後退してガイド板18を案内枠20に沿わせて後方に移動させることに より、ロック爪16とストッパー爪19とが係合し、テーブルリフター7が支持され る。この場合、ロック爪16とストッパー爪19には各々同傾斜のテーパー面16A,19 A が形成されるため、これらの係合時には、ストッパー爪19でロック爪16が持ち 上げた状態で支持することになり、このため、テーブルリフター7の荷重がスト ッパ爪19ーを介してこれを取り付けるシャーシフレーム2に加わって直接油圧シ リンダー14に加わらず、このテーブルリフター7上に荷物を載せて輸送する際に 、走行中の振動等による油圧シリンダー14の負担を軽減することができる。Next, when the cargo handling work is completed, as shown in FIG. 4, the hydraulic cylinders 14 and 14A are retracted to raise the table lifters 7 and 8 to the height of the floor surface 3A. In this case, one of the table lifters 7 abuts the holding frame 15, which closes the opening 6 of the floor surface 3A and serves as the floor surface 3A, while the other door lifter 8 serves as a load. It stands upright along the box 3 and abuts against the stopper 10 on the side of the cargo box 3, and the door / lifter 8 is locked with a locking metal fitting 21 provided on the rear surface of the cargo box 3 The lower part of the door is closed, and the upper part of the doorway 4 is closed by the shutter door 5 to close the entire surface of the doorway 4. Then, as shown in FIG. 4, the locking cylinder 17 extending forward is retracted and the guide plate 18 is moved rearward along the guide frame 20, so that the lock claw 16 and the stopper claw 19 are engaged. And the table lifter 7 is supported. In this case, the lock pawl 16 and the stopper pawl 19 are formed with tapered surfaces 16A and 19A having the same inclination.Therefore, when these are engaged, the stopper pawl 19 should support the lock pawl 16 while lifting it. Therefore, the load of the table lifter 7 is added to the chassis frame 2 to which the table lifter 7 is attached via the stopper claws 19-, and is not directly applied to the hydraulic cylinder 14, and the load is placed on the table lifter 7 for transportation. In doing so, it is possible to reduce the load on the hydraulic cylinder 14 due to vibration or the like during traveling.

【0012】 このように、本考案においては、荷箱3の内部に設けたテーブルリフター7と 荷箱3外部のドア兼用リフター8とを隣設し、荷役時にドア兼用リフター8を荷 箱3の外部に倒伏させることにより、テーブルリフター7と幅の広いフラットな 載置面を形成することができるため、貨物自動車1側の構造物との位置関係で荷 箱2の内側に幅の狭いテーブルリフター7を配置しても実質的に幅の広い積載ス ペースを確保できるとともに、荷役時以外はドア兼用リフター8は起立させて開 閉扉として使用しているため、これをコンパクトに格納することができる。As described above, in the present invention, the table lifter 7 provided inside the cargo box 3 and the door / lifter 8 outside the cargo box 3 are provided next to each other, and the door / lifter 8 of the cargo box 3 is used during cargo handling. When the table lifter 7 is laid down to the outside, a wide flat mounting surface can be formed with the table lifter 7. Therefore, the table lifter having a narrow width inside the cargo box 2 can be formed due to the positional relationship with the structure on the side of the freight vehicle 1. Even if 7 is arranged, a substantially wide loading space can be secured, and since the door / lifter 8 is used as an open / closed door upright when not loading, it can be stored compactly. ..

【0013】 以上、本考案の一実施例について詳述したが、上記一実施例に限定されるもの ではなく、本考案の要旨の範囲内で種々の変形実施が可能であり、例えば荷箱の 後面に出入口を形成した例を示したが、この出入口は左側壁や右側壁あるいはこ れら側壁面と後面とに出入口を形成する等その使用目的に応じて適宜設定すれば よい。また、出入口の上部を開閉する開閉扉はシャッター式に限らず図7に示す ように上下折り戸式の開閉扉30や図8に示すような跳ね上げ式の開閉扉31など各 種タイプに適用可能である。また、必ずしも出入口の上部を各種の開閉扉で開閉 する必要はなく出入口をドア兼用リフターによって完全に開閉することも可能で ある。さらに、昇降装置として油圧シリンダーを用い、これを直接テーブルリフ ターの支柱に取り付けた例を示したが支柱にチェーン等の連結部材を連結し、そ の連結部材を介して油圧シリンダーやエアシリンダー等の各種のシリンダー装置 によりテーブルリフターを昇降させてもよく、あるいは前記の連結部材を電動ウ ィンチ等で巻き取ってテーブルリフターを昇降させてもよく、昇降装置の構造は 適宜設定すればよい。Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-mentioned one embodiment, and various modifications can be made within the scope of the present invention. Although an example is shown in which a doorway is formed on the rear surface, this doorway may be appropriately set according to the purpose of use, such as forming a doorway on the left side wall, the right side wall, or these side wall surfaces and the rear surface. Also, the open / close door that opens and closes the upper part of the entrance / exit is not limited to the shutter type, but is also applicable to various types such as the vertically folding door type open / close door 30 as shown in Fig. 7 and the flip-up type open / close door 31 as shown in Fig. 8. It is possible. Moreover, it is not always necessary to open and close the upper part of the entrance and exit with various opening and closing doors, and the entrance and exit can be completely opened and closed by the lifter that also serves as a door. Furthermore, although an example was shown in which a hydraulic cylinder was used as the lifting device and was directly attached to the column of the table lifter, a connecting member such as a chain was connected to the column, and a hydraulic cylinder, an air cylinder, etc. were connected via the connecting member. The table lifter may be moved up and down by the various cylinder devices described above, or the table lifter may be moved up and down by winding the connecting member with an electric winch or the like, and the structure of the lifting device may be set appropriately.
