HAND GUIDE ROLLER
PROBLEM TO BE SOLVED: To provide a hand guide roller capable of securing sufficient rigidity while restraining a weight increase, by dynamically efficiently constituting a tilting mechanism for tiltably pivotally supporting a steering rod and a lock mechanism for regulating its tilting.SOLUTION: A pair of right-left fixed bearing plates 22 are separately arranged in a rear part of a travel machine body 2, and a pair of right-left movable bearing plates 25 for constituting the base end of the steering rod 13, are respectively superposed on an outside surface of these fixed bearing plates 22. The respective fixed and movable bearing plates 22 and 25 are pivotally supported by a rotary pin 27, and the steering rod 13 can be tilted in a work position and a storage position. While a lock pin 37 is extended between the movable bearing plates 25 of the steering rod 13 and made slidable between a lock position and a non-lock position, tilting of the steering rod 13 is allowed at the non-lock position of the lock pin 37 and tilting of the steering rod 13 is regulated at the lock position so that the steering rod 13 is held at the work position and the storage position by lock parts 39 formed on the fixed bearing plates 22 on the travel machine body 2 side.SELECTED DRAWING: Figure 2
【課題】操舵桿を傾動可能に軸支する傾動機構、及びその傾動を規制するロック機構を力学的に効率良く構成し、重量増加を抑制した上で十分な剛性を確保できるハンドガイドローラを提供する。【解決手段】走行機体２の後部に左右一対の固定軸受プレート２２を離間配置し、これらの固定軸受プレート２２の外側面に、操舵桿１３の基端を構成する左右一対の稼働軸受プレート２５をそれぞれ重ね合わせる。各固定及び可動軸受プレート２２，２５を回動ピン２７で軸支して操舵桿１３を作業位置と格納位置とで傾動可能とする。操舵桿１３の可動軸受プレート２５の間にロックピン３７を架け渡してロック位置と非ロック位置との間でスライド可能とする一方、走行機体２側の固定軸受プレート２２に形成したロック部３９により、ロックピン３７の非ロック位置では操舵桿１３の傾動を許容し、ロック位置では操舵桿１３の傾動を規制して作業位置及び格納位置で保持する。【選択図】図２
