ABSTRACT:
A pivoting swing maintains a support member that is rotatably attached to pivot assembly allows the support member to be rotated in any desired position. The pivot assembly includes a lock assembly that allows the position of the support member to be retained once a desired position has been found. Flexible suspension members attach the support member to the pivot assembly, thereby allowing the support member to swing back and forth once the support member has been rotated to a desired position.
