ATTACHING AND DETACHING DEVICE OF ATTACHMENT
PROBLEM TO BE SOLVED: To realize an attaching and detaching device of an attachment, with which an attachment pin is not released unintentionally during separation work of an attachment, in a simple and low-cost manner.SOLUTION: An attaching and detaching device 1 of an attachment comprises a fixing hook 3 that is provided on an arm connection part 2 connecting to an arm and that one pin of an attachment engages with, a movable hook 4 that is supported by the arm connection part 2 so as to linearly approach or separate from the fixing hook 3, and that the other pin of the attachment engages with, and a shutting hook 5 that is supported by the arm connection part 2 so as to swing in the movement direction of the movable hook 4 and that shuts or opens an opening edge 31 of the fixing hook 3. The movable hook 4 is provided with a cam groove 43, which consists of a linear groove 431 that extends in the movement direction and an oblique groove 432 that bends from an end on the fixing hook side of the linear groove 431. The shutting hook 5 is provided with an actuation pin 511 that engages with the cam groove 43.SELECTED DRAWING: Figure 1
【課題】アタッチメントの分離作業の途中でアタッチメントのピンが意図せず解放されないアタッチメント着脱装置を、簡素かつ廉価に実現する。【解決手段】アームに接続するアーム接続部２に設けられ、アタッチメントの一方のピンを掛合させる固定フック３と、アーム接続部２に支持されて固定フック３に対して直線的に接近離反し、アタッチメントの他方のピンを掛合させる可動フック４と、アーム接続部２に支持されて可動フック４の移動方向に揺動し、固定フック３の開放縁31を閉鎖又は開放する閉鎖フック５とを備え、可動フック４は、移動方向に延在する直線溝431と前記直線溝431の固定フック寄り端から曲がった斜め溝432とからなるカム溝43を設け、閉鎖フック５は、前記カム溝43に掛合する作動ピン511を設けたことを特徴とするアタッチメント着脱装置１である。【選択図】図１
