Title:
TRACK RUNNING OBJECT
Document Type and Number:
Japanese Patent JPS6474159
Kind Code:
A
Abstract:
PURPOSE:To prevent a power receiving piece from impeding its power receiving action by frost by supporting a heater, which can come into contact with and separate from a power feed rail additionally provided in a running rail, to a running main unit part and controlling the current conduction to this heater being associated with the operation of a control part. CONSTITUTION:A track running object A is driven running while receiving power from a power feed rail C, arranged along a running rail B, through a power receiving piece E. Here the track running object A pivotally supports one end of a link 23 by a shaft 22 to a mounting bracket 21 secured to a running main unit part 4, and fixing one end of an actuator arm 25 to this shaft 22, a heater 1, in which a heat generating part is built, is mounted to the other end of the actuator arm 25 through a holding bracket 26. While providing a set lever 24 in the other end of the link 23, the heater 1, by controlling this lever 24, is brought into contact with and separated from the power feed rail C, while a limit switch 3 is controlled in the time of this contact and separating operation so as to enable the current conduction to the heater 1 to be controlled.
