CLAIM OF PRIORITY

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

The present invention relates to a novel apparatus for removably mounting eyeglasses on one's nose

BACKGROUND OF THE INVENTION

Pince-nez style eyeglasses were originally popular in the early 20^th 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.

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. The slightest motion tends to displace or dislodge the frames. 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. Larger lenses, such as those that are used in conventional eyeglasses frames with temples, will require a stiffer spring to compensate for the additional weight. 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. The pinching force tends to increase with a wider nose bridge since torsion force increases as the lenses are pushed further apart. Thus, pince-nez frames available in the art are limited by the type of possible activity as well as by a particular facial features.

SUMMARY OF THE INVENTION

It is the object of the disclosed device to provide an improved version of pince-nez eyeglasses.

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.

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.

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.

In one disclosed embodiment, the eyeglasses are 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.

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.

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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

Reference will now be made in detail to embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto without detracting from the described utility thereof.

Turning now descriptively to the drawings, FIG. 1 demonstrates one contextual representation of the disclosed device. The disclosed device is the pince-nez eyeglasses 10, having adjacent lenses 20a and 20b, linked together by a bridge 30. Using backwardly from the inner frame 22 are nose pad assembly 40 which, when at rest, is configured to press against either side of the nose bridge 102 of a wearer 100. Levers 60 issue forwardly from the inner frame 22 and are connected through the pivot 42 to the nose pad assembly 40. The Levers 60 are configured to spread each pad 44 of the pad assembly 40 so that the pince-nez device may be mounted along or removed from the nose bridge 102. The pince-nez device 10 shown in FIG. 1 appears to have a rim. However, all concepts disclosed in FIG. 1 and in later figures are just as applicable to rimless frames, and frames of various geometric shapes, such as square, circular, oval, triangular, pentagonal, or any other shape of the lenses 20a and 20b, as well as all different styles of frames, such as quarter frames, half rims, etc.

FIG. 2 describes many of the novel utilities of the present invention. Shown are the lenses 20 that are disposed adjacently and are separated by a bridge 30. The bridge 30 is preferably comprised of parallel forward rods 32 issuing forwardly from the connection point and lined by a horizontal rod 34. The combination of forward rods 32 and the horizontal rod 34 forms a middle portion of the bridge 30. The combination of forward rods 32 and the horizontal rod 34 may instead be a single arching rod. The parallel forward rods 32 and the horizontal rod 34 may be connected at a point or transition elliptically as shown. The connection points 35 attach the bridge to the inner frame 22. The inner frame 22 in turn also holds the lenses 20.

Still referring to FIG. 2, the bridge 30 serves a dual purpose. The first purpose is to connect adjacent lenses 20 together to form eyeglasses. The second purpose is to offset the weight of the nose pad assembly 40. The nose pad assembly 40 comprises a first rod 46 issuing rearwardly from the pivot 42. A second rod 48 issues at an angle from the free end of the first rod 46 and runs downwardly in a moderate diagonal direction away from the axis of the lenses 20. Issuing rearwardly from a free end of the second rod 48 is a third rod 50, which is terminated by a nose pad attachment point 52 inside the actual nose pad 44. The first, second, and third rods 46, 48 and 50, respectively connecting to the two nose pads 44 of the nose pad assembly 40, are in parallel and set apart configuration with respect to each other.

The architecture created by the first, second, and third rods 46, 48 and 50, respectively, and/or the slight diagonal disposition of the second rod 48 is intended to a) place the nose pads 44 at some distance from the crest 101 on the nose bridge 102 along a side of a nose bridge 102; b) spread the pressure exerted by the pivot 42 over a wider area and thus reduce some of the discomfort felt in the nose bride area by a wearer 100; and c) serve as a weight and torsional offset to the bridge 30. The zigzag pattern produced by the first, second, and third rods 46, 48 and 50, respectively, may also be replaced by a downward arch issuing rearwardly from the pivot 42 and proceeding downwardly in substantially the same direction as the zigzag pattern shown. Depending on the desired style the zigzag pattern may contain additional or fewer twists, as long as the basic architecture, disposition of the nose pads 44 and the counterbalance to the bridge 30 are preserved.

FIGS. 3A and 3B illustrate several important novel features of the disclosed device. Shown are lenses 20 adjacently and co-linearly linked by a bridge 30. The bridge 30 connecting at connection points 32 to pivots 42 of each inner band 22 that secures each lens 20. The components of the bridge 30, namely the forward rods 32, linked by a horizontal rod 34 extend forward from the connection points 35. Two parallel arms 47, where each parallel arm 47 is attached to a pivot 42. Each arm having a lever 60 forwardly extending from the pivot 42 and a first rod 46 rearwardly extending from the pivot 42. Each arm 47 having a second rod extending at an angle from the free end of the first rod 46 at the point 46a. As illustrated in FIG. 2, the second rods 48 angle downward from the points 46a. FIGS. 3A and 3B demonstrate that the opposing rods 48 are angling away from each other at points 46a. The bend in the arms 47 that is illustrated in FIGS. 3A and 3B affords for a more concentrated and flush attachment of the pads 54, when the gap 54 is near it narrowest point, which also especially suitable for narrower nose bridges 102. Furthermore, the angle of the second rods 48 orients the attachment face 45 of each pad 44 to be more parallel with the sides of the bridge 102. The same bend in the arms 47 also leads to a generous gap 54 shown in FIG. 3B, which assists in easily mounting and dismounting of the disclosed device 10 from a wearer's nose 102 and adjusting the position of the disclosed device 10 along the length of a wearer's nose. The large variation of the gap 54 also accommodates a greater variety of nose bridge sizes without sacrificing comfort and effectiveness. In FIG. 3A the arms 47 are at a default or at rest position, with the gap 54 being its narrowest and the levers 60 facing away from each other. In FIG. 3A the levers are activated (by utilizing the fingers of a wearer) and pivoted towards the bridge 30, which causes the gap 54 to widen. Once the desired maneuver is achieved, the torsion spring in the pivots 42 causes the levers 60 to return to the position shown in FIG. 3A when they are released.

FIGS. 4A and 4B are right and left hand views, respectively, of the disclosed device 10. Shown are the nose pads 54 oriented diagonally away from the axis of the lenses 20. The bridge 30 protrudes forward of the frame above the levers 60. The levers 60 are shaped in a paddle-like form that offers optimal snag area for a user's finger tips despite the small profile of the lever component 60.

FIG. 6 demonstrates a sideview of the device 10 in the context of the preferred usage. The position of the nose pads 54 allows them to be placed across the side of a nose bridge 103, thereby capturing as much as of surface area as possible. This in turn leads to an attachment that is tolerant to motion and activity, permitting the device to be worn while engaging in various forms of physical activity.

Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
