Patent ID: 8776970

Claim:
An arrangement adapted for letting water pass by electrical conductors and their contact surfaces related to a rail structure of a system for propelling an electrically propellable vehicle by one or several batteries or a set of batteries along a roadway, comprising a plurality of roadway sections, the system comprising: “a” a plurality of roadway portions for subdividing the roadway into said roadway sections, wherein each one of the roadway sections comprises one or more elongated tracks or slits having conductors introduced therein adapted to be supplied with current and put under voltage and having contact surfaces, wherein the conductors are connectable via a switch to one or more vehicle-external power sources, including vehicle-external electric stations, for thereby enabling a charging of said set of batteries belonging to the vehicle, but primarily driving the vehicle along the roadway and the roadway sections, and “b” one or more driveable or propellable vehicles which may be driven by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit adapted for necessary distribution of power, adapted for creating required power and/or speed control, wherein said vehicle is provided on its underneath side with contact means displaceable up and down and sideways, in relation to the direction of transportation of the vehicle; wherein said elongated track and the conductors extending along the roadway and the roadway sections and wherein said contact means is coordinated with a vehicle-related control equipment for creating an adaptation of the contact means so as to at least offer a mechanical and electrical contact with said conductors and the contact surfaces thereof; wherein at least two or three tracks are disposed parallel to each other in a common rail structure, with at least two of these tracks being adapted to support and contain individual electric conductors with contact surfaces put under voltage, and wherein at least one track is disposed closer to the highest point of the roadway and adjacent to a track containing one of said conductors with contact surfaces which may be put under voltage.
