1. Field of the Invention
This application is an International Application based on U.S. Provisional Application No. 61/903,300 filed on Nov. 12, 2013.
The present invention relates generally to eyewear. More particularly, the invention relates to a system for removable engagement of lenses and components to a first or user eyewear frame. A lens sub-frame component having a frame member engaged around the periphery of preferably two lenses can be connected to the first eyewear via a snap in removable engagement at a bridge portion or can be configured to snap in and out of the viewing apertures of the main eyewear frame, to provide for easy and quick replacement, or augmentation of one or a plurality of lenses by the user to their eyewear frame. Removable engagement of charms and decorative components is also provided.
2. Prior Art
Eyewear also referred to as eyeglasses or simply glasses, have been worn by individuals for fashion as well as necessity for centuries. Prescription or corrective eyeglasses are typically employed to correct vision deficiencies such as nearsightedness (myopia), farsightedness, astigmatism, and others, and can dramatically improve a user's quality of life by improving vision. Sunglasses are a type of eyewear employing shaded, tinted, or light polarized lenses which provide protection to the user from bright visible light and even ultraviolet light. Other types of eyewear include protective eyewear, sporting eyewear, and others, where each type typically have specific lens properties to provide a certain vision characteristic.
Conventional eyewear generally comprise a frame having viewing apertures adapted to engaged lenses and temple portions typically rotationally engaged to opposite side edges of the frame. The frame can be formed from plastic or metal, while the lenses are conventionally formed from a transparent plastic or glass. In addition, frame-less glasses, unitary lenses, and other eyewear models are also conventionally known in the art.
In the fashion industry in particular, the style of the lens frame can be considered quite a fashion statement. Users may often purchase a plurality of eyeglasses each of different style, as needed for matching with different attire. Many fashionable sunglass frames also include charms or accent pieces engaged on the outside corners of the front of the frame to further increase appeal and provide jewelry of sorts to accompany the user's attire. Further, designer eyewear can be exceptionally expensive due to their connection to a certain trademarked or fashionable brand or individual, and are often sought after by the consumer looking to make a fashion or social statement. As one could imagine, because of this need to match eyewear to clothing, indoor and outdoor venues, and for work purposes, a user's eyewear collection can become quite large and in turn extremely expensive. It would thus, be desirable to be able to adapt expensive and fashionable eyewear, or eyewear a user considers comfortable, for use in multiple places such as at the beach, reading around a pool, or at work reading a computer screen.
As a an impediment of such, most conventional eyewear employ lenses which are securely affixed in their engagement with the frame such that the lenses cannot be removed without substantial skill or force, or without possibly damaging the eyewear lenses or the frame itself. This is unfortunate since a user who has inadvertently scratched or damaged the lenses cannot simply replace the lens in their existing very expensive frame. Further, should a user's venue change or viewing purpose change such as reading in dim light or bright light, the permanent nature of lenses and frames engaged with most eyewear precludes adapting it for multiple uses.
Therefor, if a lens is damaged, or should their vision change, or should their venue or viewing purpose change, a user is typically required to replace the entire eyewear assembly of frame and lenses including the fashion frame which can be quite expensive and time consuming. As such, the user may have to part with a pair of eyewear which they have become accustomed too or are particularly stylish or fashionable, and which are very expensive.
As a result, there exists in prior art many attempts to provide eyewear and eyewear devices which employ means for removable engagement of the lenses to the frame. U.S. Pat. No. 6,074,059 to Glass et. al. is one such example which teaches sunglasses with removable lenses comprising a lens and frame set which is adapted for the easy replacement and/or interchange of the removable lenses from a front side of the frame and is incorporated in its entirety by this reference.
In one embodiment in of the Glass invention, the lens is secured into the frame from the front side by a resiliently compressible barrier which is overcome in order for the lens to be received into and out of the frame. In another embodiment to Glass, the lenses are securable into the frame by friction arising between a resiliently compressible lens gasket that is attached to the periphery of the lens and an interior surface of the cross section of the viewing apertures of the frame.
However, the device to Glass falls short in many aspects. Firstly, Glass teaches that the lenses are replaced individually within their respective viewing apertures of the frame. As such the user must take great care in maintaining continuity between pairs of replaceable lenses and their insertion position, should some lenses have different prescriptive qualities, polarization, or other characteristic which must be employed in complimentary pairs.
A typical user whose is not educated in optics or lens construction may easily mistake one lens type for another, and if employed incorrectly during insertion into the frame, may distort or damage the user's vision or simply render the eyewear inoperable for its corrective purpose. Further, many lenses have asymmetric shapes and as such may be difficult to register in their engagement with the frame without custom configuring of the lens perimeters.
As such, there is a continuing unmet need for an eyewear device and system, providing a means for removable engagement of new or alternate lenses which is easily employed by the user. Such a device should advantageously provide a lens sub frame which engages one or a plurality of lenses therein, and registers the engaged sub frame in proper alignment with a first eyewear frame in a single snap-in engagement. In modes employing at least two lenses, in one mode of snap-in engagement the frame member of the sub-frame should preferably employ an engageable bridge member communicating between the two lenses therefor providing a unitary sub-frame with lenses in correct positions for the eyewear frame. Further, in such a device, the first or main eyewear frame should be configured to removably engage the sub-frame unit in a frictional or snap fit style engagement from a front surface, such that the user can easily and quickly replace a pair of lenses in a registered position on the frame, as needed, but remove them and not have a large unsightly mount viewable.
Still further, such a system should provide for the engagement to charms and decorative items to the first or main eyewear frame of the user to allow for easy and changing decoration thereof.
The forgoing examples of related art and limitation related therewith are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various limitations of the related art will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
The device and system herein disclosed and described provides a solution to the shortcomings in prior art and achieves the above noted goals through the provision of an eyewear frame engagement system, which provides a means for snap-in removable engagement of a lens sub-frame having one or a plurality of lenses engaged thereon. The user can thus employ the snap-in engagement system to easily augment the lenses of a first pair of eyewear with new or multiple different lenses in sub-framess.
In accordance with a first preferred mode of snap-in engagement, the system herein employs two lenses operatively engaged within a lens sub-frames which includes a frame member which communicates around the peripheral edges of the two lenses. The two surrounded lenses are connected via a bridge member. The communication of the frame member about the peripheral edges of the lens preferably imparts a slight or moderate compressive force onto the lenses engaged with the sub-frames, thereby providing means for securely engaging the lenses thereto. However, other means for engagement of the frame member of the sub-frames to the lenses may be employed and are anticipated. Further, other modes of the device employing a unitary lens eyewear are disclosed later.
The frame member of the sub-frames can be formed of conventional materials such as metal, wire, plastic, or the like. However, it can also be formed from any conventional materials known in the art. For example, the frame member can be formed from lengths of metal wire which bent and configured to provide a seamless engagement around the peripheral edges of the lenses. This can be accomplished by welding or otherwise soldering the ends of the wire communicating around the lens. However, engagement of the frame member to the lens in the sub-frames can be made removable by the employing of a tightening screw, removable fasteners, monofilament line, or other means known in the art.
The main eyewear frame preferably includes a first frame having two viewing apertures and preferably having a bridge portion communicating therebetween. Temples are also provided and are preferably rotatably engaged to the side edges of the first frame as is conventionally known in the art. The viewing apertures include a circumferential contact with the lenses of the main or first frame.
In a first mode of snap-in engagement for a sub-frame, engagement recesses are positioned within the viewing apertures which are configured to removably engage with, or around the exterior of each lens engaged with the sub-frames. The recesses are formed on the front side of the first frame, on the opposite side from the user's face when the frame is worn in an as used position.
If lenses are engaged in the first frame, the user can easily augment those lenses by the snap-in engagement of the sub-frames, to position the lenses of the sub-frames, in front of the lenses in the first frame. If the first frame is configured with no lenses, the user can therefor easily and quickly place and replace the lens sub-frames into the snap in engagement to the main eyewear frame as needed, and can change or replace the lenses therein by a simple subsequent snap in engagement of another sub-frames. In this mode, the bridge member of the sub-frames will simply communicate over the bridge member of the main frame when the lenses are snapped in and engaged therewith.
It is additionally noted that the perimeter or portions thereof of the circumferential contact surface and engagement recesses of the viewing apertures of the front of the main frame can be sized equal to or slightly smaller than the circumferential shape and size of the frame member of the sub-frames. Therefor, the engagement of the sub-frames into the view apertures in the snap-in engagement imparts an additional slight or moderate compressive engagement force around the circumferential peripheral edge of the sub-frames member and the engaged lenses therein providing a means for enhanced engagement thereof.
In this system, the user may have a plurality of different sub-frames with different lenses therein for different purposes such as reading, sunglasses, 3D glasses, etc. and simply insert the sub-frames of choice as needed. Additionally, as noted, the sub-frames and lenses may be employed concurrently with lenses already mounted within the two apertures of the main frame.
In other modes of the device employing a unitary lens type eyewear, the lens sub-frames includes a frame member which communicates around the periphery of a unitary lens. The main frame will include a single viewing aperture having a circumferential recess or other suitable contact surface configured to engaged the unitary lens sub-frames.
Still further, in accordance with at least one other preferred mode of the invention using a snap-in means for removable engagement, the bridge portion of the first frame surface or the main frame, will include a snap-in means for engagement of the bridge member of the sub-frames. This mode of snap in engagement of the sub-frames, employs a recess, cavity, or slot, sized to engage with and around the bridge member of the sub-frames when in the as used position. As such, the snap in engagement of the bridge member of the sub-frames to the bridge member of the first frame, provides means for added securement of the sub-frames to the first frame in the as used position.
Further, because all engagement of the sub-frames are against or to the front surface of the main frame, in plain sight, engagement to the as used position is easily accomplished as is removal.
Additionally, this surface-positioned snap-in engagement of the bridge member of the sub-frames to the bridge member of the first frame can be configured to provide for a rotational engagement, and frictional positioning during such rotation as well. As such, once snapped into a mount, the sub-frames can then be rotated out of alignment with the viewing apertures. However, maintaining the engagement of the bridge portions, thereby providing a ‘flip up’ feature of the sub-frames lenses. This mode is especially useful if the user wishes to add sunglass lenses in front of corrective lenses of the main frame, or sunglass lenses in front of corrective lenses in the main frame, or just using the sub-frame by itself which is one of a kit of sub-frames each with differing lenses in a group. Such a group could include one or a plurality of pairs of lenses engaged to individual sub-frames, where the lenses are corrective, tinted, linear polarized, circular polarized, or the like. In this mode of snap-in engagement, the snap-in mount on the main frame can be formed at manufacture, or can be adhered to the front surface at the bride of the first eyewear frame.
In yet another mode of the device, the first frame of the device may employ pre-engaged lenses within the viewing apertures and may include sub-frames engagement means disposed on the circumferential contact surface of the front of the pre-engaged lenses. For example, the first frame of the eyewear may have prescription lenses engaged thereon and the sub-frames may have tinted or polarized lenses engaged thereon which can be removably engaged within the circumferential recess in the viewing apertures disposed in front of the existing lenses. If rotational engagement is provided on the bridge of the main frame to the sub-frames, the engaged sub-frames and lenses can also be rotated out of the view of the wearer of the main frame and lenses. It is noted however, that the preferred modes of the device can be reversed, such that the disposition of the circumferential contact surface and recess allows the snap in engagement of the sub-frames to be engaged from the rear side of the first frame.

Now referring to drawings in
The lens sub-frames 26 includes frame members 28 which communicate around the peripheral edges of the lenses 32 and a bridge portion 30 engaging the two in a unit. The communication of the lens-surrounding frame members 28 about the peripheral edges of the lenses 32 is preferably configured to impart a slight or moderate compressive engagement force thereby providing means for securely engaging the lenses 32 thereto. However, other means for engagement of the frame members 28 to the lenses 32 may be employed and are anticipated.
The frame members 28 and bridge portion 30 of the sub-frames 26, in all modes can be formed of conventional materials such as metal, wire, plastic, or the like however can be formed from any conventional materials known in the art. For example, the frame members 28 can be formed from lengths of metal wire which bent and configured to provide a seamless engagement around the peripheral edges of the chosen lenses. This can be accomplished by permanently welding or soldering the ends of the wire communicating around the lens.
However, engagement of the frame members 28 to the lenses 32 can be a means for removable engagement within the perimeter of the frame members 28, such as through the employment of tightening screw, complimentary fasteners 38 and 40 as shown in
In one mode of snap in removable engagement of the sub-frames 26 to a or first frame 14, the viewing apertures 16 of the first frame 14, include a circumferential surface 22 area in front of the lenses 32, having a circumferential recess 24 (
The engaged as-used mode of the sub-frames 26 is shown in
It is additionally noted that the diameter of the circumferential surface 22 of the viewing apertures 16 of the first frame 14 can be sized slightly smaller than the perimeter of the frame members 28 of the sub-frames 26. Therefor the engagement of the sub-frames 26 into the snap in engagement with the view apertures 16 imparts an additional slight or moderate compressive engagement force around the peripheral edge of the frame member 28 and lenses 32 providing a means for enhanced engagement thereof.
In accordance with another preferred mode of the invention, the bridge portion 18 of the first frame 14 includes means for snap in engagement of the bridge member 30 of the sub-frames 26. In
In
As in all modes of the device using a recess 34 for a snap in engagement of the bridge member 30, the recess 34 is formed to have an opening 37 slightly smaller than the diameter of the bridge member 30 such that a slight expansion occurs when the bridge member is pressured to snap into engagement through the opening edge. Once positioned within the cavity forming the recess 34, the bridge member 30 cannot dismount since the opening wraps around the bridge member 30 and is smaller in diameter than the bridge member. Removal is by pulling or pressuring the bridge member 30 to expand the opening of the recess 34, to allow it to dismount from the snap in engagement.
Additionally as shown in
In yet another mode of the device 10 and system in
In this mode, the sub-frames 26 can then be removably engaged within circumferential recess 24 in the viewing apertures 16 operatively positioned in front of the existing lenses 42 which are positioned closer to the wearer's face, to now provided polarized prescription eyewear. It is noted that other combinations of lenses may also be employed, for example prescription, sport, reading, polarized, circular polarized, tinted, and other lenses can be used in any combination thereof.
In the current mode, means for removable engagement is provided through a slot 46 configured to slidably engaged or snap in a removable charm component 44. It is preferred that the slot 46 and component 44 have cross sections providing means for registered engagement, as shown in
