Patent ID: 7870938

Claim:
A collector shoe device provided with: a shoe body supported on an upper end section of a pantograph in a crosswise direction of a vehicle; a slider support body arranged above the shoe body in the crosswise direction of the vehicle along the shoe body; and a slider, which is supported and fixed on a top surface of the slider support body, and the top surface of which comes in contact with an overhead line, the slider support body comprising a center support member that is long in the crosswise direction of the vehicle, and a pair of end section support members arranged on both of the lengthwise direction end sections of the center support member, the center support member elastically deforming downward in the vertical direction across the lengthwise direction due to a load applied due to the contact between the overhead line and the slider, thereby allowing the top surface of the slider to shift in the vertical direction with respect to the shoe body, and furthermore, both of the end sections of the center support member and an inner end section, in the crosswise direction of the vehicle, of each of the end section support members being connected by a first connecting shaft arranged in the traveling direction of the vehicle, allowing them to oscillate and shift freely, and a support frame supported on the shoe body and an outer end section, in the crosswise direction of the vehicle, of each of the end section support members being connected by a second connecting shaft arranged in the travelling direction of the vehicle, allowing them to oscillate and shift freely, the both end sections of the center support member being supported so as to allow free oscillation on the shoe body via the respective end section support members, thereby allowing the entire center support member to rise and fall freely with respect to the shoe body, and the center support member provided with a rising and falling shaft in parallel with the first and second connecting shafts, this rising and falling shaft being movably fitted so as to rise and fall freely in a guide hole of the support frame supported by the shoe body.
