Abstract

A swivel joint system for hanging a heavy punching bag from an overhead support has a swivel joint defining at least first and second perpendicular pivot axes and a hanging shaft having a lower end pivotally connected to the universal joint for rotation about the first pivot axis and an upper end configured for rotatable attachment to an overhead support for free rotation about a third pivot axis. A hanging tube is pivotally connected to the universal joint for rotation about the second pivot axis, and releasably secured to a mounting plate. A plurality of attachment members are rigidly attachable at spaced locations around the mounting plate to surround the hanging tube and configured for attachment to straps at the upper end of a heavy punching bag.
