Description
【０００１】[0001]
本考案は、例えばフォークリフト等の荷役車両に適用されるフォーク伸縮装置 に関する。 The present invention relates to a fork telescopic device applied to a cargo handling vehicle such as a forklift.
【０００２】[0002]
従来、フォークリフト等の荷役車両に装備されたフォークは、異なる長さのも のに代えない限り、フォーク長さが一定であった。この為、大きさの異なるパレ ットを用いてフォーク作業を行なう事業所に於ては、パレット長さよりフォーク 長さが長い場合には、フォークの先端がパレットから飛出してしまい、奥にある 荷物等を傷付ける惧れがあった。又、鞘フォークを用いて大きなパレット（荷） に対応する場合には、鞘フォークの取付作業に手間が掛る、鞘フォークが作業中 に抜ける、フォーク厚さが厚くなってパレット穴に差し込めない、狭いＬ字通路 を通過できない等の問題があった。 Conventionally, a fork mounted on a cargo handling vehicle such as a forklift has a constant fork length unless it is replaced with a different length. For this reason, at business establishments that perform fork work using pallets of different sizes, if the fork length is longer than the pallet length, the tip of the fork will pop out of the pallet and be in the back. I was afraid to damage my luggage. Also, when using a sheath fork to handle a large pallet (load), it takes time to install the sheath fork, the sheath fork comes off during the work, and the fork thickness becomes too thick to insert into the pallet hole. There were problems such as not being able to pass through a narrow L-shaped passage.
【０００３】[0003]
本考案は、叙上の問題点に鑑み、これを解消する為に創案されたもので、その 目的とする処は、パレット長さに応じてフォーク長さをフォークのオペレータは 運転席での簡単な操作で可変できる様にしたフォーク伸縮装置を提供するにある 。 The present invention was devised in order to solve this problem in view of the above-mentioned problems. It is to provide a fork telescopic device that can be changed by various operations.
【０００４】[0004]
本考案のフォーク伸縮装置は、基本的には、支持体と、支持体に重合してこれ より長い使用状態から支持体の基部付近に折畳まれる格納状態まで移動可能な折 畳支持体と、支持体に対して折畳支持体を移動させる駆動装置と、から構成した 事に特徴が存する。 The fork telescopic device of the present invention basically comprises a support and a folding support which is superposed on the support and movable from a longer use state to a stored state where the support is folded near the base of the support. It is characterized in that it is composed of a drive device for moving the folding support body with respect to the support body.
【０００５】[0005]
【作用】 駆動装置を作動させると、支持体に対して折畳支持体が使用状態や格納状態に 移動されてフォーク長さが可変される。When the drive device is operated, the folding support body is moved to the use state or the storage state with respect to the support body, and the fork length is changed.
【０００６】[0006]
以下、本考案の実施例を、図面に基づいて説明する。 図１は、本考案の第一実施例に係るフォーク伸縮装置の伸長状態を示す側面図 。図２は、図１の２−２矢視図。図３は、図１の３−３矢視図。図４は、短縮状 態を示す図１と同様図である。 フォーク伸縮装置１は、支持体２、折畳支持体３、駆動装置４とからその主要 部が構成されて居り、フォークリフト等の荷役車両に適用される。 支持体２は、フォーク伸縮装置１の基本部分を為すもので、この例では、水平 片５と、これの後部から上方へ延びる垂直片６と、これの背面に付設された上下 の爪片７とから成る通常のフォークにしてあり、上下の爪片７が荷役車両の昇降 体（フィンガーバ）Ａに掛着される。 折畳支持体３は、支持体２に重合してこれより長い使用状態から支持体２の基 部付近に折畳まれる格納状態まで移動可能なもので、この例では、支持体２の水 平片５に上から外嵌されてこれより長い断面略逆Ｕ型の枠材８と、これの後部か ら上方そして後方に延びて支持体２の垂直片６の側部に位置する側面略鉤型の左 右のブラケット９とから成る鞘フォークにしてあり、左右のブラケット９の後部 が支持体２の垂直片６の後面中位に付設された支片１０に横軸１１で水平状態か ら垂直状態まで俯仰可能に枢結されている。 駆動装置４は、支持体２に対して折畳支持体３を移動させるもので、この例で は、支持体２の垂直片６の後面中位に付設された油圧等のシリンダ１２と、これ のロッド側に付設されたヘッド１３と、これを摺動可能に案内する前後のヘッド ガイド１４と、ヘッド１３と折畳支持体３のブラケット９の中程とに横軸１５， １６で枢結された左右のリンク１７とから成っている。而して、シリンダ１２は 、荷役車両の運転席から制御できる様にしてある。 次に、この様な構成に基づいて作用を述解する。 図１は、折畳支持体３が支持体２の水平片５に重合してこれより長い使用状態 を呈している。つまり、フォーク伸縮装置１としては、伸長状態になり、フォー ク長さがＬ1 になる。 この様な状態に於て、荷役車両の運転席からシリンダ１２を制御してこれを短 縮作動させると、ヘッド１３、リンク１７を介して折畳支持体３が仰起されて図 ４の如く支持体２の基部付近に折畳まれて格納状態になる。つまり、フォーク伸 縮装置１としては、短縮状態となり、取扱う荷物の高さに依りフォーク長さがＬ 2 又はＬ3 になる。 従って、パレット長さに呼応したフォーク長さにする事ができ、折畳支持体３ の先端がパレットから飛出して奥にある荷物を傷付ける等の惧れがなくなる。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an extended state of a fork telescopic device according to a first embodiment of the present invention. FIG. 2 is a view on arrow 2-2 of FIG. 1. FIG. 3 is a view on arrow 3-3 of FIG. 1. FIG. 4 is a view similar to FIG. 1 showing the shortened state. The fork extension / contraction device 1 is mainly composed of a support 2, a folding support 3, and a drive device 4, and is applied to a cargo handling vehicle such as a forklift. The support body 2 forms a basic part of the fork extension / contraction device 1, and in this example, a horizontal piece 5, a vertical piece 6 extending upward from a rear portion thereof, and upper and lower claw pieces 7 attached to the back surface thereof. Is a normal fork, and the upper and lower claw pieces 7 are hooked on the lifting body (finger bar) A of the cargo handling vehicle. The folding support 3 is one that is polymerized on the support 2 and is movable from a longer use state to a stored state in which it is folded near the base of the support 2. In this example, the water of the support 2 is used. A frame member 8 which is fitted onto the flat piece 5 from above and has a substantially U-shaped cross section which is longer than this, and side surfaces which extend upward and rearward from the rear portion of the frame member 8 and are located on the side portions of the vertical piece 6 of the support body 2. A hook-shaped left and right bracket 9 and a sheath fork are used, and the rear portions of the left and right brackets 9 are attached horizontally to the support piece 10 attached to the middle of the rear surface of the vertical piece 6 of the support 2 by the horizontal axis 11. It is pivoted so that it can be lifted up to the vertical state. The drive device 4 moves the folding support body 3 with respect to the support body 2. In this example, a hydraulic cylinder or the like 12 attached to the middle of the rear surface of the vertical piece 6 of the support body 2 and this. A head 13 attached to the rod side of the head, front and rear head guides 14 for slidably guiding the head 13, and a middle portion of the head 13 and the middle of the bracket 9 of the folding support body 3 by means of horizontal shafts 15 and 16. It consists of the left and right links 17 that have been made. Thus, the cylinder 12 can be controlled from the driver's seat of the cargo handling vehicle. Next, the operation will be described based on such a configuration. In FIG. 1, the folding support 3 is superposed on the horizontal piece 5 of the support 2 and is in a longer use state. In other words, the fork telescopic device 1 is in the extended state and the fork length is L1become. In such a state, when the cylinder 12 is controlled from the driver's seat of the cargo handling vehicle and the cylinder 12 is shortened, the folding support 3 is lifted up via the head 13 and the link 17, and as shown in FIG. It is folded in the vicinity of the base of the support body 2 and put in a stored state. That is, the fork retractor 1 is in a shortened state, and the fork length is L depending on the height of the load to be handled. 2 Or L3become. Therefore, the length of the fork can be made to correspond to the length of the pallet, and there is no fear of the tip of the folding support 3 protruding from the pallet and damaging the luggage in the back.
【０００７】 次に、本考案の第二実施例を図５乃至図７に基づいて説明する。 第二実施例は、折畳支持体３を前側の枠材１８と後側の左右のアーム１９とで 構成した点、これらを横軸（ピン）２０で枢結した点、折畳支持体３の使用状態 時には枠材１８とアーム１９との上面を面一にした点、支持体２の垂直片５と折 畳支持体３の枠材１８にストッパ２１を設けた点、支持体２の水平片５の先端と 折畳支持体３の枠材１８のストッパ２１に丸みを付けて折畳支持体３の円滑な移 動を可能にした点、支持体３のアーム１９の後部を支持体２の下爪片７に横軸１ １で枢結した点、駆動装置４のリンク１７をアーム１９に横軸１６で枢結した点 、が第一実施例と異なる。 この様なものは、図６の状態からシリンダ１２を短縮作動させると、図７の如 く、折畳支持体３が支持体２の水平片５を案内としてストッパ２１同士が当合す るまで二つ折りに畳まれ、格納状態の折畳支持体３の高さを小さくできる。Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the folding support 3 is composed of a front frame member 18 and rear left and right arms 19, and these are pivotally connected by a horizontal shaft (pin) 20. In the use state, the upper surfaces of the frame member 18 and the arm 19 are flush with each other, the vertical piece 5 of the supporting member 2 and the frame member 18 of the folding supporting member 3 are provided with the stoppers 21, and the supporting member 2 is horizontal. The tip of the piece 5 and the stopper 21 of the frame member 18 of the folding support 3 are rounded so that the folding support 3 can be smoothly moved. It differs from the first embodiment in that the lower claw piece 7 is pivotally connected to the lower shaft 7 by the horizontal axis 11 and the link 17 of the drive device 4 is pivotally connected to the arm 19 by the horizontal shaft 16. In such a case, when the cylinder 12 is shortened from the state of FIG. 6, as shown in FIG. 7, the folding support body 3 guides the horizontal piece 5 of the support body 2 until the stoppers 21 abut each other. The folding support 3 can be folded in half and the height of the folded support 3 in the retracted state can be reduced.
【０００８】 尚、支持体２は、先の実施例では、水平片５と垂直片６を備えたものであった が、これに限らず、例えば水平片５だけのものでも良い。 折畳支持体３は、第一実施例では、一つ折れ、第二実施例では、二つ折れであ ったが、これに限らず、例えば三つ折れ以上でも良い。 駆動装置４は、先の実施例では、シリンダ１２を用いたが、これに限らず、例 えば電動モータ等を用いても良い。 駆動装置４は、先の実施例では、ヘッドガイド１４を設けたが、これに限らず 、例えばシリンダ１２の曲げ強度に問題がなければ、省略しても良い。 支持体２の水平片５の先端は、第二実施例では、丸みを付けたが、これに限ら ず、例えばローラ等を回転可能に設けても良い。Although the support 2 is provided with the horizontal piece 5 and the vertical piece 6 in the above embodiment, the support 2 is not limited to this and may be, for example, only the horizontal piece 5. The folding support 3 has one fold in the first embodiment and two folds in the second embodiment, but the present invention is not limited to this, and may be three folds or more. Although the drive device 4 uses the cylinder 12 in the above-described embodiment, the drive device 4 is not limited to this, and an electric motor or the like may be used, for example. Although the drive device 4 is provided with the head guide 14 in the previous embodiment, the drive device 4 is not limited to this, and may be omitted if there is no problem in bending strength of the cylinder 12, for example. Although the tip of the horizontal piece 5 of the support 2 is rounded in the second embodiment, the present invention is not limited to this, and for example, a roller or the like may be rotatably provided.
