Eyeglasses Retention Mechanism

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.

Description

CLAIM OF PRIORITY[0001]This application claims the benefit of a provisional application No. 63 / 044,448, filed on Jun. 26, 2020, the contents of which are fully incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a novel apparatus for removably mounting eyeglasses on one's noseBACKGROUND OF THE INVENTION[0003]Pince-nez style eyeglasses were originally popular in the early 20th century. The pince-nez style eye-glass frames comprise adjacent lenses that are separated by a bridge-like spring that exerts a force on an arch, thereby exerting a downward force on both lenses. This force causes the lenses to fold into each other and thereby pinch the nose bridge of a wearer between them. The pinching force is used to maintain the pince-nez frame mounted on a user's nose. Pince-nez remains an elegant and highly portable vision aid solution. However, this solution has enjoyed limited success due to serious drawbacks as explained below.[0004]One major d...

AI Technical Summary

Benefits of technology

[0008]It is another object of the disclosed device to provide a pince-nez frame that doesn't get displaced with slightest movement of a wearer.

[0009]It is still another object of the disclosed device to provide a pince-nez pinching mechanism that securely holds a pince-nez frame in place with increased comfort to the wearer.

[0010]It is still a further object of the disclosed device to provide a full balanced frame, where the pinching mechanism is balanced against the bridge, which extends forward of the bridge, and where the lenses balance the lateral dimension of the frame.

[0012]The pad arms are made in a twisted and substantially flared pattern so as to capture as much of surface area on each side of a nose bridge as possible. Furthermore, a twisted configuration as shown in the figures allows for increased comfort by alleviating pressure on the skin surface of a nose that is caused by the springs. Additionally, the added space resulting from the extended pad arms, for example the twisted or zigzag configuration, and where the nose pads are slightly flared backwardly away from the frame, allowing for more distribution of tension of the spring and for greater flexibility of positioning of eyeglasses on a wearer's nose.

[0013]A bridge links the two adjacent lenses of the pince-nez. The preferred bridge extends forwardly by a distance that is proportional to the extension of the nose pads. The bridge serves the dual purpose of a) linking the adjacent lenses; and b) providing equilibrium of torque and weight to offset the downward force of the nose pads.

Problems solved by technology

This force causes the lenses to fold into each other and thereby pinch the nose bridge of a wearer between them.

However, this solution has enjoyed limited success due to serious drawbacks as explained below.

One major downside of traditional pince-nez is that they tent to slip off of a nose at the least alacrity of motion.

Therefore, a user may only wear them when engaging in a very mild activity, such as sitting down at a desk or reading in one spot.

Pince-nez that are known in the art are unsuitable for any type of physical activity, such as running, walking or even turning one's head.

Besides for this significant limitation, the pinching force of existing pince-nez frames is also quite uncomfortable and cannot be worn over a nose for prolonged periods of time.

The aforementioned limitation also causes the pince-nez lenses to be quite small to keep the weight down.

While a stiffer bridge may, to some degree, solve the problem of maintaining pince-nez on a nose while engaging in mild physical activity, it also induces a greater degree of soreness and pain to the wearer's nose bridge area, which reduces the utility and appeal of a stiffer bridge embodiment.

An additional downside is that pince-nez are less than ideal for wider noses.

Thus, pince-nez frames available in the art are limited by the type of possible activity as well as by a particular facial features.
