Abstract
The disclosed device is eyeglasses frame that is self-maintained upon a nose using pad arms attached to a nose bridge via a spring in each of the pad arms. The spring may be activated via one or more levers. As such, a lever would be activating a torsion spring by pulling the pad arms apart to allow for a passage of a nose bridge. Once the pad arms have been placed over the desired location along a nose bridge of a wearer, or removed therefrom, the levers are released returning the pad arms to a pinched orientation with respect to the nose bridge.
Claims14
A pince-nez vision aid device comprising:
- two frames disposed adjacently;
- said frames separated by a bridge;
- said bridge having a middle portion;
- a nose pad assembly comprising two arms;
- each of said two arms pivotably attaching to said bridge on either side of said middle portion;
- wherein said arms extend rearwardly from points of pivotal attachment of said arms to said bridge, wherein said arms attach levers issuing forwardly from the points of attachment, two springs;
- wherein said pivotal attachments are respectively spring-loaded by the springs, wherein the springs exert pressure on the nose bridge of a user proportional to the angular extension of the arms;
- a plurality of removable and replaceable nose pads of different sizes;
- wherein each said arm is configured to receive a nose pad, selected from the nose pads, by slidably threading an attachment member terminating said arm into an opening in the selected nose pad, wherein all the nose pads when attached to the respective attachment members are entirely disposed rearward of a plane defined by the two frames;
- wherein when the levers are pressed, the rearward extension of the arms provides an adjustable gap between the attachment members terminating the arms to accommodate the nose pads of different sizes and corresponding nose bridges of different widths, wherein at least partial compensation of the pressure is achievable by selection of nose pads of larger size and greater surface area.
A method of constructing a pince-nez vision aid device to accommodate different widths of nose bridges of different users, the method comprising:
- disposing two frames adjacently;
- separating said frames by a bridge having a middle portion;
- providing a nose pad assembly having two arms;
- pivotably attaching said arms to said bridge on either side of said middle portion;
- wherein said arms extend rearwardly from points of pivotal attachment of said arms to said bridge, wherein said arms attach levers issuing forwardly from the points of pivotal attachment;
- providing a plurality of nose pads of different sizes which are removable and replaceable;
- configuring the arms to receive the nose pads by slidably threading attachment members terminating the arms into respective openings in the nose pads, wherein all the nose pads are entirely disposed rearward of a plane defined by the two frames;
- providing an adjustable gap between the attachment members terminating the arms, by the rearward extension of the arms, when pressing the levers to accommodate the nose pads of different sizes and corresponding nose bridges of different widths;
- spring-loading said pivotal attachments thereby exerting pressure on the nose bridge of the user proportional to the angular extension of the arms;
- and
- selecting a pair of nose pads from the nose pads of different sizes to accommodate a nose bridge width of a particular user;
- at least partially compensating for the pressure by selection of nose pads of larger size and greater surface area.
