Abstract
A securing structure for an optical piece is disclosed and which comprises: a hub portion; a surrounding portion connected to the hub portion; a plurality of recess structures formed or otherwise provided in at least one of the hub portion and the surrounding portion and which are at least partially open on at least one side; and a rib structure that at least partially separates the plurality of recess structures. The structure is capable of use with an apparatus for securing and clamping optical lenses (e.g., spectacle lenses) requiring edge-machining.
Claims37
A securing structure for securing an optical piece during machining of the optical piece, the securing structure comprising:
- a hub portion having a generally cylindrical surface and a centerline axis;
- a surrounding portion connected near an end of the hub portion and having a portion that is concentric with, and which projects generally annularly outward away from, the generally cylindrical surface of hub portion;
- a plurality of recess structures, formed and extending into at least one of the hub portion or the surrounding portion, are positioned at least partially generally along the centerline axis;
- and
- a rib structure that generally spans across the centerline axis of the hub portion and separates the plurality of recess structures so that they are spaced apart and distinct from one another;
- wherein each of the recess structures comprises a plurality of side surfaces and an interior-most surface, with such surfaces joined to one another so as to provide bounded voids, except that such voids are at least partially open on at least one side to a generally concave surface for receiving an optical piece, and which generally concave surface generally extends across at least a portion of the hub portion and at least a portion of the surrounding portion;
- and
- wherein the rib structure includes:
- (i) a surface that is at least partially coincident with the generally concave surface for receiving the optical piece and (ii) at least two additional portions, each of which is at least partially coincident with a respective side of a respective one of the plurality of recess structures, the rib structure extending from the generally concave surface for receiving the optical piece to the interior-most surface.
