Abstract: A bi-plate ball bearing is configured for horizontally mounting between a base and a chair. The ball bearing has an upper plate and a lower plate defining a ball bearing race and a tension member holding the plates together disposed through a central rotational axis of the bi-plate ball bearing. The tension member may be configured as a threaded metal tube fixed to a first one of the upper plate and the lower plate and held to a second one of the upper plate and the lower plate by a nut. The threaded metal tube defines a passage through the central rotational axis of the bi-plate ball bearing through which power and control wiring may pass. The bearing may provide a cost-effective swivel bearing for chair that includes powered electronics, for which it is desired to pass wiring from the swiveling chair into a chair base.

Abstract: A locking support assembly for a casino chair uses a support plate with a chair mount having a fixed pin protruding upwards from the support plate opposite to the mount. The pin may serve as a sole or primary guide member in the support plate to guide the support plate into horizontal alignment with a latch mounted inside a beam. The beam holds the support plate in close but unlocked engagement by a lower groove, to resist loads imposed by an attached chair. A releasable latch inside the beam receives the pin to provide locked engagement between the support plate and the beam. The beam may be fastened to a vertical surface of a gaming machine or other object. The support plate and attached chair can be released from the beam by inserting a tool through a keyhole in the beam to release the latch, while pulling the support plate outwards.
