Patent ID: 7575210

Claim:
A glass holder device for the treatment of optical glasses ( 4 , 4 ′) or other substrates and of the kind which includes optical glasses, glass holder grips, an axially elongated bar ( 1 ) of cylindrical cross-section for supporting the glass holder grips, and a frame for supporting the bar horizontally, is characterized by said optical glass has a peripheral outer edge ( 40 , 40 ′), said bar ( 1 ) including a series of evenly spaced positioning notches ( 10 ) for removably mounting a respective plurality of glass holder grips to the bar and next to one another, said glass holder grip ( 2 ) comprising: an axially elongated body ( 20 ) having opposite upper and lower end portions and an axis extending the length of said body, said upper end portion including hanging means ( 21 , 22 , 25 ) for joining the holder grip in a removable way to a respective notch ( 10 ) in the bar ( 1 ) and locking means ( 11 , 23 , 12 , 25 ) for preventing free rotation of the holder grip ( 2 ) relative to the bar ( 1 ), the upper end portion of the body ( 20 ) being bent to form an inverted U-shaped hook ( 21 ) that is downwardly open for receiving the bar and, at least in part, adapted to be received in the positioning notch ( 10 ) cut in the bar ( 1 ), said lower end portion of said body ( 20 ) having a support stop ( 36 ), the stop projecting perpendicularly outwardly from the body ( 20 ) and the outer edge of the optical glass being adapted to be supported on the stop ( 36 ) and positioned relative to a holding means ( 3 ), and said holding means ( 3 ) comprises a V-shaped holder having two lever arms ( 31 , 31 ′) that are joined to one another at a common apex, the apex defining a mountable end and the lever arms extending from the mountable end and terminating in deflectable free ends ( 32 , 32 ′) that are adapted to expand to receive and contract to form a tight clutching gripping engagement with the outer edge of the optical glass ( 4 , 4 ′), the mountable end being mounted to the upper end portion of the body for relative rotation about a swivel axis ( 42 ), the free ends ( 32 , 32 ′) of the lever arms ( 31 , 31 ′) and the stop ( 36 ) positioning the optical glass ( 4 , 4 ′) in substantially vertical relation and parallel to the axis of the body ( 20 ).
