Abstract: Cylindrical first and second components have a joint between the components. The joint includes a male coupler with a first extent slidably received in the second component and a second extent formed with male coupling threads. Female carrier threads are provided on the male coupler. The joint also includes a female coupler slidably received in the first component. The female coupler has female carrier threads. The female coupler has female coupling threads adapted to removably couple with the male coupling threads of the male coupler. Tubular carriers have ends. Carrier threads are removably received in the carrier threads of the couplers. An elastic member has a central region located within the threads of the couplers and extending through the upper and lower carriers.

Abstract: An outrigger support assembly is for use with a frame of a bicycle. Front and rear wheels are coupled to the frame. Handle bars are coupled to and extend upwardly from the frame. Pedals are secured to and extend laterally from the frame adjacent to the forward end of the frame. A drive chain operatively couples the pedals and the rear wheel. A seat is mounted on the frame between the front and rear wheels. The support assembly includes two outrigger wheels positionable on opposite sides of the frame and on opposite sides of the front and rear wheels. Support structures on each side of the frame, each have an interior end couplable to the frame and an exterior end with an outrigger wheel rotatably supported on an associated exterior end. Hinges on each support structure move between lowered and raised orientations.
