Description

本発明は、片手でトレイを持ち上げて運搬することができるトレイ把持具の改良に関する。 The present invention relates to an improvement of a tray gripper that can lift and carry a tray with one hand.

矩形で底が浅いトレイは、小物部品の収納、運搬に適しており、広く利用されている。一般の作業では、作業者がトレイの縁に両手を掛けて持ち上げ、運搬する。しかし、一方の手が塞がっているなどの理由から、片手でトレイを運ぶ必要が生じることがある。この場合には、片手でトレイを把持することができる治具（吊具）が便利であり、この種の吊具が提案されている（例えば、特許文献１参照。）。
実用新案登録第３０２９７４２号公報（図１） A rectangular tray with a shallow bottom is suitable for storing and transporting small parts and is widely used. In general work, an operator puts both hands on the edge of the tray and lifts and carries it. However, it may be necessary to carry the tray with one hand, for example because one hand is blocked. In this case, a jig (hanging tool) that can hold the tray with one hand is convenient, and this type of hanging tool has been proposed (for example, see Patent Document 1).
Utility Model Registration No. 3029742 (FIG. 1)

特許文献１を図５及び図６に基づいて説明する。
図５は従来の吊具をトレイに取り付けるときの手順を説明する図であり、（ａ）に示すように、片方の手１０１に吊具１０２を持ち、トレイ１０３の縁部１０４に第１のフレーム１０５を介して係止爪１０６を引掛ける。 Patent Document 1 will be described with reference to FIGS. 5 and 6.
FIG. 5 is a diagram for explaining a procedure for attaching a conventional hanging tool to the tray. As shown in FIG. 5A, the lifting tool 102 is held in one hand 101 and the first edge 104 of the tray 103 is first. The locking claw 106 is hooked through the frame 105.

次に（ｂ）に示すように、親指１０７で第２のフレーム１０８の上面を押さえながら人差し指１０９を第２のフレーム１０８の下面に当てる。次に、第２のフレーム１０８をピン１１０を支点に矢印（１）の方向へ揺動させる。この結果、係止爪１０６と係止爪１１１との間隔がトレイ１０３の幅よりも広くなる。 Next, as shown in (b), the index finger 109 is applied to the lower surface of the second frame 108 while pressing the upper surface of the second frame 108 with the thumb 107. Next, the second frame 108 is swung in the direction of the arrow (1) with the pin 110 as a fulcrum. As a result, the interval between the locking claw 106 and the locking claw 111 is wider than the width of the tray 103.

次に（ｃ）に示すように、係止爪１０６と係止爪１１１との間隔がトレイ１０３の幅よりも広い状態を維持したまま、吊具１０２全体を矢印（２）の方向に移動させ、第２のフレーム１０８の係止爪１１１をトレイ１０３の縁部１０４に対応する位置まで下げる。 Next, as shown in (c), the entire suspension 102 is moved in the direction of the arrow (2) while the gap between the locking claw 106 and the locking claw 111 is maintained wider than the width of the tray 103. Then, the locking claw 111 of the second frame 108 is lowered to a position corresponding to the edge 104 of the tray 103.

図６は従来の吊具でトレイを吊るまでの手順を説明する図であり、（ａ）に示すように、親指１０７と人差し指１０９を第２のフレーム１０８から離す。すると、第２のフレーム１０８はピン１１０を支点に回転可能に連結されているので自重により矢印（３）のように揺動し、係止爪１１１は矢印（４）のように動いてトレイ１０３の縁部１０４に突き当たる。 FIG. 6 is a diagram for explaining a procedure until the tray is hung with the conventional hanger. As shown in FIG. 6A, the thumb 107 and the index finger 109 are separated from the second frame 108. Then, since the second frame 108 is rotatably connected to the pin 110 as a fulcrum, it swings as indicated by an arrow (3) by its own weight, and the locking claw 111 moves as indicated by an arrow (4) to move the tray 103. It hits the edge 104.

次に、（ｂ）に示すように、手１０１を引き上げれば、係止爪１０６、１１１はトレイ１０３の縁部１０４に引掛かる。第１のフレーム１０５と第２のフレーム１０８にはトレイ１０３の重量がかかり、係止爪１０６と係止爪１１１が接近する方向のモーメントが働くが、第２のフレームの揺動は制限されるので、２本のフレームのアーチ形状が維持されてトレイ１０３が持ち上がる。 Next, as shown in (b), when the hand 101 is pulled up, the locking claws 106 and 111 are hooked on the edge 104 of the tray 103. The weight of the tray 103 is applied to the first frame 105 and the second frame 108, and a moment in the direction in which the locking claw 106 and the locking claw 111 approach each other acts, but the swing of the second frame is limited. Therefore, the arch shape of the two frames is maintained and the tray 103 is lifted.

ところで、図５（ｂ）で示したように、親指１０７と人差し指１０９とで第２のフレーム１０８を揺動させる作業が必須となる。この作業は、ピン１１０より図左に親指１０７と人差し指１０９とを置き、ピン１１０より図右に残りの指を置く必要がある。握り位置が不適当なときには握り位置を修正する必要がある。 By the way, as shown in FIG. 5B, the operation of swinging the second frame 108 with the thumb 107 and the index finger 109 is essential. In this operation, it is necessary to place the thumb 107 and the index finger 109 on the left side of the pin 110 and the rest of the finger on the right side of the pin 110 in the drawing. When the grip position is inappropriate, it is necessary to correct the grip position.

不慣れな作業者、すなわち未熟練の作業者にとっては使い勝手が悪く、作業性がよいとは言えない。
未熟練の作業者でも容易に作業が行える、使い勝手の良い治具が望まれる。 For unskilled workers, that is, unskilled workers, it is not easy to use and the workability is not good.
