Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
173 words
A device for connecting two separate parts, particularly in the field of optics, comprising a circular plate having a central opening and an annular flange, a plurality of pairs of levers positioned internally of the flange, each of the levers being pivotally mounted on the plate at points radially outside the central opening, a detent means on the inner end of each lever, which is that most adjacent the central opening in the plate, resilient means engaging the outer end of each lever of each pair and constantly urging the levers of each pair to their positions in which the detent means are in their innermost positions, and a plurality of buttons each of which is slidably mounted in the annular flange between the outer ends of the levers of a pair of levers with their inner ends engaging the outer ends of the levers and their outer ends external to the flange for manual depression, whereby depression of the buttons will cause the detent means to move outwardly toward the annular flange.
