TELESCOPIC LOCK DEVICE IN TELESCOPIC LEG DEVICE
PROBLEM TO BE SOLVED: To provide a telescopic lock device in a telescopic leg device arranged in a high place work device.SOLUTION: An operation mechanism (25) situated upward of a telescopic lock mechanism (24) with a lock body (44) for locking detachably to a rack gear of a telescopic leg and having an operation lever (35), coupling means (26) capable of a linear movement in a vertical direction as well as for coupling the operation mechanism and the telescopic lock mechanism, and a spring (54) for energizing the coupling means downward are provided and it is in a configuration in which the lock body (44) is detached from a rack gear (23a) by a traction of the coupling means (26) upward by the operation of the operation lever and a motion direction conversion mechanism (27) consisting of actuating means (47) for a linear movement in a vertical direction along with the coupling means between a lower end of the coupling means and the telescopic lock mechanism, rotating means (48) extending from the lock body at opposite side of the lock gear and gradient arm means (49) of which both ends pivoted to the actuation means and the rotating means respectively are arranged.SELECTED DRAWING: Figure 10
【課題】高所作業装置に設けられた伸縮脚装置における伸縮ロック装置を提供する。【解決手段】伸縮脚のラック歯に係脱自在に係止するロック体(44)を備えた伸縮ロック機構(24)の上方に位置して操作レバー(35)を有する操作機構(25)と、前記操作機構と伸縮ロック機構を連結すると共に上下方向に直線移動自在な連結手段(26)と、前記連結手段を下向きに付勢するスプリング(54)を設け、前記操作レバーの操作により連結手段(26)を上向きに牽引することにより前記ロック体(44)をラック歯(23a)から離脱させる構成とされ、前記連結手段の下端部と前記伸縮ロック機構の間に、該連結手段に同行して上下方向に直線移動する作動手段(47)と、前記ロック歯の反対側でロック体から延設された回動手段(48)と、両端部がそれぞれ前記作動手段と回動手段に枢結された傾斜アーム手段(49)とから成る運動方向変換機構(27)を設けている。【選択図】図１０
