ABSTRACT:
A telescopic arm assembly for use in conjunction with a dental chair unit and attachable to a post of the unit. A main arm defines a slot at its inner end to receive an arm support including a pivot pin about which the arm may move in an upright manner. A limit stop on the support controls arm movement. A secondary arm supports a tool holder at its outer end and is provided with pin-shaped followers at its inner end which ride along guides extending lengthwise of the main arm to prevent rotation of the secondary arm within the main arm.
