ABSTRACT:
A detachable swivel mechanism is disclosed for an outdoor chair adapted for regular or reclining use. The mechanism consists of a base, adjustable telescoping support members which may be attached to many different sizes and types of outdoor chairs and swivel means to which the telescoping members and base are connected. In one embodiment, the mechanism may have a circular base having a diameter of at least the same size as the width of the seat of the chair to which it is attached, and means at the periphery of the base providing a circular track thereon. A plurality of rigid supports may be provided to hold the seat above the circular base. Roller means are used to mount the lower end of these supports for movement along the track to permit the seat to swivel, and means overlying the circular track are used to hold the roller means on the track.
