Abstract:

A swivel assembly for a tire comprises a clamp assembly adapted to be secured to a header tube, a swivel first member suspended from the clamp to pivot either parallel to or perpendicular to a longitudinal axis of the header tube, a swivel second member which is suspended from the swivel first member to pivot 90 relative to the pivotal motion of the swivel first member, and a swivel third member which can rotate about the swivel second member. The swivel first member is pivotally mounted to the clamp via an upper pivot pin and the second swivel member is pivotally mounted to the swivel first member by a second lower pivot pin. The center-to-center distance between the upper and lower pivot pins is preferably less than about 3″. Additionally, the lower pivot pin can have a diameter that is less than the diameter of the upper pivot pin. Lastly, the swivel assembly can include a tether which extends over the header tube to which the clamp assembly is secured which has opposite ends secured to opposite sides of the lower pivot pin. The tether is sufficiently strong to support the weight of the tire swing, the swivel assembly, and anyone on the tire swing should the swivel assembly catastrophically fail.
