ABSTRACT:
An angle adjusting mechanism for a supported article includes a fixedly positioned holding member and a rotary member relatively rotatable with respect to the holding member. A plurality of plates are disposed between the rotary and holding members. The holding member is provided with a plurality of claw teeth at the inner periphery of one arcuate segment and the rotary member is provided with a respective plurality of claw teeth over a different arcuate segment of the inner periphery thereof. A first plurality of fixed plates, including claw teeth on their peripheries, engage the teeth of the holding member, on a second plurality of rotary plates, including claw teeth on their peripheries, engage the claw teeth on the inner periphery of the rotary member. A clamping bolt is provided to draw the rotary and holding members together and compress the fixed and rotary plates together fixing their relative orientations, thereby to fix the rotative (angular) orientation of the rotary member with respect to the holding member.
