Retaining device for reading glasses and foldable reading glasses
First Claim
1. Foldable reading glasses having an open position and a closed position for use by a wearer comprise:
- a lanyard;
a plurality of weights adjustably mounted on the lanyard, whereby the wearer adjusts the position of the plurality of weights on the lanyard;
a first frame having a front surface and a rear surface;
a second frame, having a front surface and a rear surface, the second frame being hingedly coupled to the first frame, such that the first frame and the second frame are hingedly engaged such that the front surface of the first frame may be disposed in opposition to the front surface of the second frame, when the first frame and the second frame are hingedly disposed in the closed configuration;
a first temple piece is that does not extend to the wearer'"'"'s first ear hingedly coupled to the first frame at one end of the first temple piece and is coupled to the lanyard at an opposite end of the first temple piece, opposite of the one end of the first temple piece, such that the first temple piece at least partially covers the first frame, when disposed in the closed configuration;
a second temple piece that does not extend to the wearer'"'"'s second ear is hingedly coupled to the second frame at one end of the second temple piece and is coupled to the lanyard at an opposite end of the second temple piece, opposite of the one end of the second temple piece, such that the second temple piece at least partially covers the second frame, when disposed in the closed configuration;
wherein the plurality of weights have a collective mass selected to counterbalance the weight of the foldable reading glasses, when the foldable reading glasses are disposed in the open configuration on a bridge of a nose of the wearer, and the lanyard is disposed over each of the wearer'"'"'s ears and behind the wearer'"'"'s neck.

Abstract
A retaining device for reading glasses comprises a lanyard and counterweights slidable engaging the lanyard. The counterweights are movable by sliding such that the counterweights hang in behind a user'"'"'s ears to retain glasses on the user, when foldable temple pieces do not include ear pieces, such that the temple pieces do no rest on a user'"'"'s ears. Instead, the lanyard extends over the user'"'"'s ears and the counterweights apply a force, due to gravity, that acts opposite to the force of gravity on the glasses, retaining the glasses on the user'"'"'s nose. For example, the glasses may be foldable into a pendant and may be retained on the user'"'"'s neck until needed.
