The present invention generally relates to eyeglass frames and lens rims, and more particularly relates to eyeglass lens rims that are readily interchangeable with an eyeglass frame section such that the lens rim is held in proper position with respect to the eyeglass frame section using, at least, a channel section and magnetic retaining elements incorporated into one or both of the lens rim and eyeglass frame. The eyeglass frame and lens rim may be manufactured from a variety of materials including various thermoplastics or metals, the latter including aluminum or titanium. With the ability to easily interchange or substitute eyeglass lenses and lens rims used with the eyeglass frames, the entire appearance of the eyeglasses, and thus the appearance of the wearer, can be readily altered, allowing the wearer to quickly change his or her “look and feel” for different activities, events, or different times of the day or night.
Eyeglasses or glasses are worn by millions of people around the world, whether for normal sight correction, for close-up reading, for protection from the sun or snow glare, or simply for the way they make the wearer look. Many, if not most people, have multiple sets of eyeglasses that can be worn for a variety of uses or activities, including for everyday use, for reading, and for outdoor use and activities. Often, eyeglass wearers have different designs and styles of frames and lenses that allow the wearer to have a different “look” based upon which eyeglasses are worn for particular activities. While eyeglass wearers may have multiple sets of glasses to wear for different purposes or activities, they often have one particular set of glasses that are most comfortable, either because of the design, the frame shape, the shape and orientation of the temple/side pieces, or the design and comfort of the nose cushions or nose bridge.
To accommodate the desire of wearers to have different eyeglass designs, various interchangeable or replacement eyeglass lenses have been created over the years. Several of the designs have been manufactured, and some of which are currently being commercialized.
Two examples includes U.S. Pat. Nos. 8,641,188 and 7,850,301, both for Eyewear Frames With Magnetic Lens Attachments and both issued to DiChiara (the DiChiara patents). The '188 DiChiara patent and the '301 DiChiara patent each disclose a pair of eyeglass lenses that are attachable to an eyeglass frame using magnets or magnetically attractive material. The description and disclosure provided in the DiChiara patents provides for the magnets to be incorporated into each individual lens such that each lens is attached and removed from the eyeglass frame individually. Such a design does not provide any means for changing the style, shape or look of the eyeglasses through use of a lens rim that maintains the lenses.
Another example of a system is shown in U.S. Pat. No. 7,661,815 for a Eyeframe With Interchangeable Lenspieces Held by a Magnetic Closure and Interchangeable Lens System, issued to Lipawsky (the “'815 patent”). The '815 patent describes a mechanism for interchanging lenspieces within a rimwire eyeglass frame that uses a magnetic closure and rotating center section to hold the lenspieces in place. The rotating center section of the rimwire eyeglass frame is susceptible to breakage and the process for manufacturing such a device is fairly complex.
A further system, that is being commercialized is shown in U.S. Pat. No. 5,642,177 for Detachable Sunglasses with Magnets issued to Nishioka (the '377 patent”). As described in the '377 patent, the sunglasses are attached to the eyeglass frame, both having the same shape by a center located magnet. The design of the '377 patent is to provide sunglasses to be used by the wearer who has prescription glasses and does not wish to have a separate set of prescription sunglasses. There is no suggestion in the '377 patent for a system or lens mechanism that allows the wearer to alter the shape, style or look of his or her glasses over simply making them sunglasses.
As described, none of these above designs and products fully addresses the desire of wearers to readily substitute the lens rim of a set of eyeglasses, while still using the same eyeglass frame, and provide a means to alter the entire look, aesthetics, and style of the eyeglasses. Moreover, many of the prior art devices and interchangeable eyeglasses are difficult to manufacture and/or are difficult and clumsy use or operate. To be useful, such devices must not only be easily manufactured, but must also be available in a variety of materials, shapes, styles, and colors, in order to achieve market success and meet the objective of allowing the user to readily alter his or her “look.” Accordingly, such prior devices have not achieved market wide success or utility.
What is needed is an interchangeable eyeglass system that allows for ready substitution of the lens rim, including the two lenses, into a fixed eyeglass frame, such that with the interchangeability of the lens rim and associated lenses, the entire look and image of the eyeglasses may be altered. Such a design using both magnetic retaining elements and a channel section within the eyeglass frame and/or lens rim has not been created or achieved in the prior art. Such an eyeglass system would allow wearers to easily change their entire “look” with an easy interchanging of eyeglass rim and lenses.
The above described problems that are inadequately or incompletely resolved by prior art designs, are addressed and solved by the present invention.
A preferred embodiment of the invention is an interchangeable eyeglass lens rim and eyeglass frame system, said system comprising (a) a lens rim encircling and holding a pair of eyeglass lenses; (b) at least one magnetic element incorporated within said lens rim; (c) an eyeglass frame component having a channel section along one edge into which said lens rim fits; and (d) at least one magnetic element located within said eyeglass frame component such that said at least one magnetic element attracts said at least one magnetic element within said lens rim, and thereby firmly maintains said lens rim in position within said channel section and against said eyeglass frame component.
Another embodiment of the invention is an eyeglass frame and lens rim set wherein said lens rim is interchangeable, said frame and lens rim set comprising (a) an eyeglass frame component having a cut out section along a lower edge; (b) at least a first magnetic section incorporated within said cut out section of said eyeglass frame; (c) a lens rim component fully encircling a pair of eyeglass lenses; (d) at least a second magnetic section incorporated along a top edge of said lens rim component; whereby with said lens rim component properly positioned within said eyeglass frame component and within said cut out section, said second magnetic section attracts said first magnetic section and holds said lens rim component firmly in place with said eyeglass frame component in said cut out section.
A further embodiment of the invention is an interchangeable eyeglass lens rim and eyeglass frame system, said system comprising (a) a lens rim encircling and holding a pair of eyeglass lenses, said lens rim having a channel section along said lens rim upper side; (b) at least one magnetic element incorporated within said lens rim; (c) an eyeglass frame component having a lower side that securely fits into said channel section of said lens rim; and (d) at least one magnetic element located within said eyeglass frame component such that said at least one magnetic element attracts said at least one magnetic element within said lens rim, and thereby firmly maintains said eyeglass frame component in position within said channel section and against said lens rim.
