DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) 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.

(12) 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

(13) 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. Issuing 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.

(14) FIG. 2 describes many of the novel utilities of the present invention. Shown are the lenses 20a and 20b 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 3.5 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 as shown in FIG. 8. 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 20a and 20b.

(15) Still referring to FIG. 2, the bridge 30 serves a dual purpose. The first purpose is to connect adjacent lenses 20a and 20b 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.

(16) 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.

(17) FIGS. 3A and 3B illustrate several important novel features of the disclosed device. Shown are lenses 20a and 20b 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 20a and 20b. 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 43 is near its narrowest point, which is especially suitable for narrower nose bridges 102. Furthermore, the angle of the second rods 48 orients the attachment face 4.5 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 43 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 43 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 43 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 43 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.

(18) 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 20a and 20b. 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.

(19) 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.

(20) FIGS. 7A and 7B are side views of the disclosed eyeglasses frame 10 showing frames 20 20a and 20b connected by a bridge 30. Unlike the bridge shown in prior figures, the bridge 30 in FIGS. 7A and 7B is shown as a single curving arch, that slightly protrudes forward from the frames 20a and 20b. The bridge 30 may also be a completely straight and non-arching or arching vertically or arching towards the wearer. Also shown are the pad arms 47 issuing rearwardly from the pivot 42 and forwardly from the pivot 42 in the form of the levers 60.

(21) Notably different are the attachment points 52, which form a perpendicular rod attaching to the free end of the third rods 50. The attachment points 52 may have the upper 5 end 52a and the lower end 52b. Alternatively, either the upper or the lower end 52a or 52b may be left out on a particular embodiment. The attachment points 52 are substantially parallel with the vertical dimension 55 (x-axis) of the frames 20. When worn on a user's nose, the less forwardly pronounced bridge 30 and the vertical pad arms 47 balance each other in terms of weight. Shown one the pads 54 is an elongated opening 53.

(22) FIG. 8 show the disclosed embodiment 10 having frames 20a and 20b joined by a bridge 30. The bridge is a single curving rod with a forward leaning section 31 and straight portions 30. Alternatively, the bridge 30 may form a single uninterrupted arch.

(23) FIG. 9 demonstrates the removable pads 54. The attachment point 52 is threaded into the elongated opening 53, preferably using either the upper end 52a or the lower end 52b as the leading member. Once the leading member clears the inner ridge 59, the pad is pulled vertically up (or down depending on which end 52a or 52b is the leading member) and over the trailing end of the attachment point 52. The size of the elongated opening 53 and the inner elongated channel 57 while larger than shown in FIGS. 1-6 can be kept to a minimum as the pads 54 are preferably made out of flexible material that can easily stretch to increase the necessary opening. The removable nose pads enable the wearer to replace the nose pads with a nose pad of different shape, size or design, which dimensionally may be more appealing or suitable to the particular wearer. The disclosed embodiment of the frame 10 may come prepackaged with nose pads that are of several different shapes and sizes, or simply in multiples of the same size, but having varying levels of stiffness or frictional coefficient. FIG. 10 demonstrates a unitary pad 54 having 2 pad portions 54a and 54b, linked together by a bridge portion 54c. Preferably, the unitary pad 54 is preferably removable, and is used to increase the grip of the frames around a nose bridge of a wearer, which also increasing the comfort level of the frames shown, for example, by spreading the pressure of the pads 54 and the weight of the frames 20a and 20b over a greater area.
