Abstract

A powered bicycle trailer for propelling a bicycle, a human rider and cargo having frame, a vehicle-mounted adapter that dismountably attaches to a bicycle, a connecting arm for rotatably connecting the frame to the vehicle-mounted adapter such that the frame is rotatable around a vertical axis with respect to the connecting arm. The trailer having a power mechanism having a multi-functional control assembly capable of generating an output drive to a ground wheel, a power transmission system mechanically coupled to an output drive of the power mechanism and capable of driving the ground wheel and the control assembly and trailer are rapidly mountable and dismountable from the bicycle by a quick connect and disconnect mechanism.

Claims

1. A powered bicycle trailer for propelling a bicycle and a human rider, comprising:

a trailer frame;

an adapter for connecting to a bicycle;

a connecting arm for rotatably connecting the trailer frame to the adapter such that the frame is rotatable about at least one of a horizontal axis and a vertical axis relative to the bicycle;

a power generation system that attaches to the trailer frame;

a first control assembly that attaches to the bicycle, facilitating rider control of the power generation system and a second control assembly that attaches to the power generation system;

a ground engaging member;

a power transmission system mechanically coupled to an output drive of the power generation system and capable of driving the ground engaging member; and

wherein the trailer frame and control assembly is rapidly mountable and dismountable from the bicycle by a quick release coupling between the first and second control assemblies.

2. The bicycle trailer as recited in claim 1 wherein the vehicle-mounted adapter attaches adjacent to a hub of a rear wheel of a bicycle.

3. The bicycle trailer as recited in claim 1 wherein the vehicle-mounted adapter attaches adjacent a seat post of a bicycle.

4. The bicycle trailer as recited in claim 1 wherein the power generation system is an electric motor.

5. The bicycle trailer as recited in claim 1 further comprising a fuel tank and a means for delivering fuel from the fuel tank to the power means, where the power means is a combustion motor capable of running on gasoline or diesel fuel.

6. The bicycle trailer as recited in claim 5 wherein the power means further comprises a hybrid power system incorporating an electric motor.

7. The bicycle trailer as recited in claim 1 further comprising an external cowling adapted to fit over the power system and power transmission system and provide access thereto.

8. The bicycle trailer as recited in claim 1 wherein the ground engaging member comprises a wheel assembly mounted on the frame and having a tire constructed of rubber or other elastomer and an axle.

9. The bicycle trailer as recited in claim 1 wherein the power generation system further comprises an output drive shaft, and:

a first pulley mounted to the output drive shaft of the power means;

at least a second pulley fixed to a drive axle;

one of a belt or chain for transferring output power between the first pulley and second pulley; and

wherein the drive axle and second pulley have a common axis of rotation parallel to the axis of rotation of the output drive shaft of the power generation system.

10. The bicycle trailer as recited in claim 1 wherein the quick release coupling between the first control assembly and second control assembly are attached by means of the attracting forces of dissimilar pole magnets.

11. The bicycle trailer as recited in claim 1 wherein the first coupling mechanism of the connecting arm incorporates a forked end and the vehicle-mounted adapter incorporates protruding pins extending outwardly therefrom, the forked end configured to dismountably interface with the pins.

12. The bicycle trailer as recited in claim 11, wherein the first coupling mechanism of the connecting arm further comprises a tension spring-biased engageable latch for retaining the pin within the forked end.

13. The bicycle trailer as recited in claim 1, wherein the second coupling mechanism of the connecting arm is configured with pin openings to receive and retain a vertical hitch pin;

and

the frame further comprises a vertical hitch pin, an upper hitch tongue and a lower hitch tongue, the upper hitch tongue and lower hitch tongue each configured with vertically-oriented pin openings capable of interfacing with the pin openings in the connecting arm and receiving a vertical hitch pin for rotatably securing the connecting arm to the frame such that the frame is permitted to rotate around a vertical axis in relation to the connecting arm.

14. The trailer of claim 1, wherein the frame further comprises an extensible and retractable front portion wherein the length of the frame can be made longer to allow stowage of cargo.

15. A powered bicycle trailer for propelling a bicycle, a human rider, and cargo, comprising:

a frame for attachment to a bicycle;

a vertical and horizontally aligned axis of rotation positioned between the frame and the bicycle permitting relative rotation of the frame relative to the bicycle;

a power means supported on the frame having a first throttle cable and capable of generating an output drive;

a power means control system for mounting on the bicycle comprising a throttle control attached to a second throttle cable and a quick connect and disconnect device for connecting the second throttle cable to the first throttle cable;

a power transmission system mechanically coupled to an output drive of the power means for driving a ground engaging member; and

wherein the trailer is rapidly mountable and dismountable via the quick connect and disconnect device between the first and second throttle cables.

16. The bicycle trailer as recited in claim 15 wherein the quick connect and disconnect device between the first throttle cable and second throttle cable are attached by means of the attracting forces of dissimilar pole magnets.

17. A method of propelling a bicycle, a human rider, and cargo, comprising the steps of:

attaching a trailer having a frame to a bicycle;

positioning a vertical and horizontally aligned axis of rotation between the frame and the bicycle permitting relative rotation of the frame relative to the bicycle;

supporting a power means on the frame having a first throttle cable and capable of generating an output drive;

mounting a power means control system on the bicycle comprising a throttle control attached to a second throttle cable and a quick connect and disconnect device for connecting the second throttle cable to the first throttle cable;

coupling a power transmission system mechanically between an output drive of the power means and a ground engaging member; and

one of rapidly mounting and dismounting the trailer from the bicycle via the quick connect and disconnect device between the first and second throttle cables.

18. The method as set forth in claim 17 further comprising the steps of attaching the quick connect and disconnect device between the first throttle cable and second throttle cable by means of the attracting forces of dissimilar pole magnets.
