FRAME OF PANTAGRAPH AND PANTAGRAPH HAVING FRAME

摘要

PROBLEM TO BE SOLVED: To provide a frame of a pantagraph in which an equivalent mass is reduced, and a lower frame and a balancing rod do not have to be lifted up.;SOLUTION: A frame 3 of a pantagraph comprises an upper frame 31 and a lower frame 32. The upper frame 31 and the lower frame 32 support a collector head 2 so that the collector head is freely displaced in a vertical direction. A base end side of the lower frame 32 is pivoted so as to freely oscillate, and a tip end side thereof is directed downward relative to a horizontal state. A base end side of the upper frame 31 is connected to the tip end side of the lower frame 32 with an intermediate hinge 33 in a manner in which a cross angle can be varied, and during power collection, the tip end side of the upper frame is directed upward relative to the horizontal state.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
