Abstract
A bicycle towing device in which a plurality of aligned rigid bars are connected by means of a coupling so that one bar can rotate with respect to the other along the alignment axis of the bars. Hub and pin arrangements are connectable to the free ends of the bars and have axes of rotation perpendicular to the alignment axis of the rods. The hub and pin arrangements are connectable to the respective vehicles to allow one vehicle to move with respect to the other while being towed.
Claims7
A towing device for vehicle comprising:
- at least two rigid bars;
- a coupler for connecting the two bars in substantially coaxial alignment, said bars being rotatable one with respect to the other along an alignment axis, said at least two rigid bars having free ends disposed distally from the coupler;
- a connector for each free end of the rigid bars, said connector being rotatably coupled with the free end about a first rotation axis perpendicular to the alignment axis, said connector for connection to the vehicle on a second rotation axis perpendicular to the first rotation axis and the alignment axis, said connector including a pin and a hub sleevable on the pin, at least one of the pin and hub being connectable to the vehicle;
- said coupler including a male portion having sectors extending radially outwardly from the alignment axis and female portion having recesses extending radially outwardly from the alignment axis for mating relationship with the sectors, said male and female portions including confronting surfaces of the respective sectors and recesses for engaging each other and securing the coupler together, said male and female portions being rotatable for decoupling the coupler.
