産業上の利用分野
本考案は、固定アームと可動アームとで対象物
を掴むフオーク装置に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fork device that grips an object using a fixed arm and a movable arm.
従来技術
第１図に示すように、横杆１で連結された左右
固定アーム２，３に左右可動アーム４，５をピン
６で回動自在に枢着し、左右固定アーム２，３に
枢着した左右シリンダ７，８のピストン杆７ａ，
８ａを左右可動アーム４，５に枢着連結すると共
に、その左右シリンダ７，８を第２図に示すよう
にバルブ９を介してポンプ１０に接続したものが
知られている。Prior Art As shown in Fig. 1, left and right movable arms 4 and 5 are rotatably connected to left and right fixed arms 2 and 3 connected by a horizontal rod 1 with pins 6, The piston rods 7a of the left and right cylinders 7 and 8,
It is known that the pump 8a is pivotally connected to the left and right movable arms 4 and 5, and the left and right cylinders 7 and 8 are connected to a pump 10 via a valve 9 as shown in FIG.
しかし、この構造であると配管抵抗の差、回転
部（ピン６部分）の抵抗差等により左右可動アー
ム４，５は同時に回動せずに一方のみが回動し、
その後に他方が回動することになる。 However, with this structure, the left and right movable arms 4 and 5 do not rotate at the same time, but only one of them rotates, due to differences in piping resistance, resistance differences in the rotating part (pin 6 part), etc.
Then the other one will rotate.
このために、第３図に示すように小さな対象物
１１を掴む場合には一方の可動アーム５が回動し
て対象物１１を掴んだ後に他方の可動アーム４が
回動して対象物１１を掴むので、左右可動アーム
４，５で対象物１１を掴むまでに時間が掛り、作
業能率が低下してしまう。 For this reason, when grasping a small object 11 as shown in FIG. Therefore, it takes time for the left and right movable arms 4 and 5 to grasp the object 11, which reduces work efficiency.
考案の目的
左右可動アームを同時に回動できると共に、左
右不揃いの大きさの対象物でも掴むことができる
ようにすることを目的とする。Purpose of the invention The purpose is to enable the left and right movable arms to rotate at the same time, and also to be able to grasp objects with uneven sizes on the left and right sides.
考案の構成
左右固定アームに左右可動アームを回動自在に
連結し、左右可動アームをトーシヨンバーで接続
し、そのトーシヨンバーを左右可動アームの回動
中心と同一位置としたもの。Structure of the device The left and right movable arms are rotatably connected to the left and right fixed arms, the left and right movable arms are connected by a torsion bar, and the torsion bar is located at the same position as the center of rotation of the left and right movable arms.

３，２４にピン２８で枢着連結してある。Embodiment FIG. 4 is a perspective view of a fork device, in which left and right fixed arms 20 and 21 are connected by a pair of horizontal rods 22 and 22, and left and right movable arms 23 and 24
are rotatably connected with a pin 25, and left and right cylinders 26, 27 are pivotally connected to left and right fixed arms 20, 21.
The piston rods 26a and 27a are the left and right movable arms 2.
3 and 24 by a pin 28.
前記左右可動アーム２３，２４にはトーシヨン

ーシヨンバー２９の中間直線部２９ａは同一位置
となつている。 A torsion bar 29 is connected to the left and right movable arms 23 and 24, and the torsion bar 29
is the intermediate straight portion 29a and both side bent portions 29b, 29b.
The intermediate straight portion 29a is rotatably supported by the horizontal rod 22 via the flange 30, and is located at the same position as the pin 25, thereby forming the first and second movable arms 23, 24. The center of rotation of the torsion bar 29 and the intermediate straight portion 29a of the torsion bar 29 are at the same position.
そして、トーシヨンバー２９の両側折曲部２９
ｂ，２９ｂが左右可動アーム２３，２４に連結し
てある。 And both side bent portions 29 of the torsion bar 29
b, 29b are connected to left and right movable arms 23, 24.
しかして、左右可動アーム２３，２４はトーシ
ヨンバー２９で連結されているから同時に回動
し、小さな対象物でも迅速に掴むことができて作
業効率が向上する。 Since the left and right movable arms 23 and 24 are connected by the torsion bar 29, they rotate at the same time, and can quickly grasp even small objects, improving work efficiency.
また、トーシヨンバー２９はフレキシビリテイ
があるから左右可動アーム２３，２４は異なるス
トロークだけ回動でき、第６図に示すように左右
の大きさが異なる対象物３１でも掴むことができ
る。 Further, since the torsion bar 29 has flexibility, the left and right movable arms 23 and 24 can rotate by different strokes, and as shown in FIG. 6, objects 31 of different sizes on the left and right sides can be grasped.
