Means for securing an observation instrument to a supporting stand |
摘要 |
The invention contemplates a universal-action joint for adjustable mounting of an observation instrument upon a support, such as a conventional floor stand. The joint is of the ball and socket variety but incorporates two separate means for frictionally loading the parts against relative displacement. The first of these loadings is resilient and at a minimum level, designed to lightly retain an adjusted positioning; the second loading is selectively applied for much greater frictional engagement, to the point of effectively locking the parts against dislodgment from adjusted position.
