  • Patent number: 5623322
    Abstract: A pull-down member is pivotably and ratchetly attached to the distal end of the end-piece of each eyeglass temple. Each pull-down member is pivotably displaceable to the end-piece at a series of angles, and thereby provides a snug fit of the eyeglasses on the user's face. In one embodiment, the pull-down member comprises a disk-shaped core having an edge on which is attached an elongated appendage which is the portion of the pull-down member abutting against the user's ear. The edge of the core also includes a series of notches which are biased by a ball and spring mechanism to provide the pivotable and ratchetable displacement of the pull-down member relative to the end-piece of the eyeglass temple. In another embodiment of the pull-down member, the core has a central opening defined by a series of teeth.

  • Patent number: 5548351
    Abstract: A method for mounting safety shields onto eyeglass temples and a kit for carrying out that method. A temple of an eyeglass frame is placed in a channel forming part of a side shield thereafter, a pin is inserted into an opening formed in the side shield to create a friction fit between the temple, the channel and the pin which attaches the side shield to the temple. The side shield is placed in its operative position before the pin is inserted into the opening and the friction fit resulting from the insertion of the pin into the opening holds the side shield in its operative position. The kit includes a side shield having a longitudinally extending channel into which a longitudinally extending eyeglass temple may be inserted. The channel has an open lateral end through which the temple may be inserted and a supporting lateral end against which the temple may be supported. The side shield further includes an opening extending transversely to both the longitudinal direction and the supporting lateral wall.
