Current collector for amusement park bumper cars

A current collector arrangement for an amusement park bumper car, comprising:

• a wire mesh stretched overhead above said bumper car;
• a collector tube for collecting current from said wire mesh;
• a floor with metal panels to which current is conducted from said wire mesh;
• a roller means at a substantially small distance from said collector tube for collecting current from said wire mesh;
• freely rotating spring-supported mounting means for mounting said roller means;
• said roller means having a convex-turned surface;
• and a bowl for enclosing a major portion of said roller means;
• said roller means with said convex surface maintaining contact with said wire mesh along areas of support of said wire mesh when said wire mesh sags between said areas of support, said bowl being fixed to said mounting means so that the opening of said bowl is held substantially parallel with said wire mesh during movement of said collector tube with said bumper car;
• said mounting means including a rod;
• a ring attached to said rod;
• and spring means enclosing said rod between an end of said current collector tube and said ring attached to said rod, said rod sliding inside said current collector tube.

• supporting arm means fixedly attached to said mounting means and supporting said roller means at a substantially fixed horizontal distance from said collector tube;
• said mounting means comprising further a rod/sliding in said current/collector tube;
• said supporting arm means comprising two relatively short arms in the end region of said rod and attached at substantially right angles for holding an axle of said roller means;
• a ring attached to said rod;
• and spring means enclosing said rod between an end of said current collector tube and said ring attached to said rod.
