ABSTRACT:
A dental chair attachment for supporting an implement such as a light assembly, a hand piece delivery device or other device. The attachment is arranged for the pivotal movement of the implement about a supporting post. The attachment is arranged so that the periphery of the post is not in contact with the pivoting member of the implement. Upper and lower collar bases secured to the post support an inner sleeve that has an internal diameter larger than the diameter of the post. An outer sleeve which supports the pivoting member is rotatively mounted to the inner sleeve. The pivoting member including the outer sleeve, as it pivots, does not contact the periphery of the supporting post. Resilient rings of the upper and lower collar bases are forced radially inward against the periphery of the post to secure the attachment to the post.
