This invention relates to eyewear, and more particularly relates to eyewear adapted to have a single release point for the arm(s) and lens(es).
Traditional eyewear, including glasses, safety goggles and sunglasses, comprise frames and eyewires which securely retain the lenses in front of the eyes. In the case of cast metal eyewires, which have been rare in the art, the lenses have traditionally been released from the eyewires using a different release mechanism that the mechanism securing the arms to the eyewires, unnecessarily weighing down the frames and subverting design freedom.
Glass and sunglass lenses are usually used for vision correction and/or for reducing glare, transmission of sunlight, or brightness to a wearer, and are commonly broken, scratched or rendered inutile. Because sunglasses are ornamental to some extent, or decorative in appearance, and because users often choose sunglass lens colors appealing to their personal tastes without regard for utility, lenses are often interchanged for purely aesthetic reasons. In other instances, lenses are interchanged for medical reasons.
Although nearly all commercially-produced sunglasses are formed from polymeric materials, usually through injection molding to save production costs, there remains a market for sunglasses made from durable aluminum, titanium, or metal allow frames, including sunglasses made from molded rather than stamped metal components. These species of sunglasses were commercially successful in some embodiments, but suffered from a variety of design flaws limiting commercial viability, including limited ability to flex to fit user's with differing head sizes (especially women), weak and flexible nose bridges which distorted while bearing worn, reduced strength frames resulting from attempts to preserve metal in production and reduce weight, and multiple release points in the eyewires for the lenses and arms.
As sunglasses are being worn by ever increasing numbers of people, a market is reemerging for durable metal allow eyewear who believe polymeric sunglasses in any embodiment are cheap. The increasing demand for sunglasses specifically and eyewear generally has resulted in a proliferation of designs for sunglasses. Thus some sunglasses are designed primarily to meet functional objectives, while others are more stylish.
In order the meet the needs unmet by the prior art, the present disclosure is made with an object of the present invention to improve and cure deficiencies in the art. There exists a need in the art for eyewear with a single release point for the arms and lenses, which is inexpensive to manufacture, and adapted to facilitate quick interchanging of lenses.
From the foregoing discussion, it should be apparent that a need exists for eyewear with a single release point for the arms and lenses.

One object of the present invention is to provide eyewear with eyewires adapted to have only a single release point for an arms and lens.
As shown in
In various embodiments, two eyewires 102 are permanently or detachably affixed to a nose bridge (indicated at 302 below). In other embodiments, the eyewires 102 are affixed together or formed as a single integrated piece. In these embodiments, a single eyewire 102 envelopes or circumscribes two lenses and is adapted to straddle a wearer's nose.
The eyewire 102 in the shown embodiment is interrupted at the point where the arm 114 engages the eyewire 102. The eyewire 102 does not form a single, uninterrupted ovoid circumscribing the entire lens. Rather a break is formed in the outer lateral edge as further described below in relation to
The eyewire 102 may be fabricated from titanium, aluminum, steel, brass, gold, gold plating, carbon fiber, metal alloys, nylon, elastomeric or polymeric materials, or organic materials such as wood, or other materials known to those of skill in the art, using means known to those of skill in the art, including mold injection, 3D printing, or digital metal laser sintering (DMLS).
The proximal end of the arm 114 is indicated at 202 while the distal end is indicated at 204. Each eyewire 102 comprises a circuitous rim 206 adapted to receive and secure an inserted and detachable lens. In some variations, the rim 206 defines a track, groove 412, recess, or slot for receiving the lens.
The eyewires 102 affix to a nose bridge 302.
Two prongs 404, 402 form above and below the recess 406 which interrupts the circumscribion of the eyewire 102b. Both the upper prong 402 and the lower prong 404 jut away (in the shown embodiment laterally) from the eyewire 102 for hingedly affixing to an arm 114 or any arm known to those of skill in the art. The upper prong 402 and lower prong 404 cantilever from the main portion of the eyewire 102.
An aperture 408 forms in both the upper prong 408 and the lower prong 404 for receiving a screw, bolt, nut, shaft, rod or other joining member. The aperture 408 may be tapped as known to those of skill in the art. In various embodiments, the arm 114 snaps into recesses in the upper prong 402 and/or the lower prong 404.
When the screw inserting, traversing or positioning within the upper prong 402 and the lower prong 404 is removed, the eyewire 102 flexes with applied tensile for the prongs 402, 404 and/or the top and bottom of the eyewire 102, releasing an enclosed lens. This screw may also be detached to remove, interchange or replace the arm 114.
The pair of glasses 100 may include, without limitation, sunglasses, prescription glasses, wraparound sunglasses, safety glasses, bifocals, welding glasses, goggles, and visors. Suitable materials for the glasses 100 and lenses may include, without limitation, titanium, metal alloy, aluminum, polymeric materials, cellulose acetate, organic materials like wood and ivory, and any combination of materials. The lenses 110a-b may be glass or plastic.
The eyewire 102 forms a generally annular shape that is configured to receive similarly shaped and dimensioned lenses which contour an inner surface of the eyewire 102. Though, in other embodiments, other shapes are possible or preferred. The entire eyewire 102 piece (not just the rim or adjoining section) divides or bifurcates for form the recess 406.
The recess 406 facilitates interchangeability of the lenses and arms. The recess 406 is also adapted to reduce stress that is generated by the pressure and strain applied by the arms to the eyewire 102. The recess 406 also absorbs stress, strains, and pressure that arise from manipulation and donning of the glasses. The recess 406 is defined and disposed at a corner junction of the eyewire 102.
As shown, the arms on the sunglasses 100-400, or in various other embodiments, may comprise a plurality of arm segments, wherein each arm segment comprises a separate component of the arm hingedly connected to either a preceding arm segment or the eyewire 102.
The outer surface of the eyewire 102 disposed in front of the recess 406 may be indented, recessed, or concave such that the surface forms a concave recess 410 for abutting a cantilever 136 on the arm 114 and stopping axial rotation of the arm 114 relative to the eyewire 102 on a lateral or longitudinal plane.
The rearward surface of the eyewire 102 defines a concave recess 452 for receiving a squish pad (indicated generally at 500 in
A single screw 454 is used to affix the arm 114 to the eyewire 102 and to close the eyewire 102 at the upper prong 402 and lower prong 404. The arm 144 pivots about the screw 454, which screw is oriented in some embodiments such that its long axis (or longitudinal axis) is orthogonal to the plane of motion of the arm 114.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
