Abstract: A head-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.

Abstract: Structure and method for face form retention in eyeglasses and eyeglass frames for substantially preventing creep from altering the face form. The method comprises providing an eyeglass frame front having a space in the bridge region for receiving a metallic strip, providing the metallic strip having a width approximately matching the width of the space in the eyeglass frame front and a thickness that is less than its width, and fastening the metallic strip in the space in the bridge region so that the width of the metallic strip rigidifies the eyeglass frame front to retain its face form. Various specific methods and structures are disclosed.

Abstract: The present eyewear includes a pair of lenses, a pair of releasable connectors connected to respective inner ends of the lenses, a pair of temples pivotally connected to respective outer ends of the lenses and a rigid strap connected between rear ends of the temples. The strap is generally U-shaped having substantially parallel legs connected to an arc-shaped base, the substantially parallel legs being connected to rear ends of the temples and when worn, the arc-shaped base extends along the back of a user's head. A tab is permanently secured to one of the inner ends of the lenses or frames and upon joining the releasable connectors, extends to the other of the inner ends of the lenses or frames in order to stabilize the releasable connectors.

Abstract: A spectacle frame including at least one member, having a metal core part and a moulded part, the metal core part is an interior part of the at least one member and the moulded part is a composite material part comprising a material having a matrix material and reinforcement material embedded in the matrix material, whereby a spectacle frame or a member of a spectacle frame can be manufactured using composite materials while still allowing the frame or the member to be adjusted, and whereby the frame or the member can readily be shaped, adjusted as regards the curvature etc. by forcing the member to take the desired shape, and the metal core part will counteract the composite materials natural tendency to return to the initial shape, whereby the frame or the member will remain in the desired shape.

Abstract: The invention is a bridge structure for rimless glasses that includes a rear bridge portion, a front bridge portion; and fastening means for fastening the rear bridge portion to the front bridge portion. Typically, the rear bridge portion is made of plastic and the front bridge portion is made of metal, usually titanium.

Abstract: The invention is directed to a reinforced nose bridge structure, eyeglasses employing the reinforced nose bridge structure, and methods of making reinforced nose bridge structures and eyeglasses. A reinforced nose bridge structure includes an elongated body and a wire extending along the body for most of its length. The ends of the wire project from the body to form a pair of spaced-apart nose pad supports. Respective nose pads are mounted at the ends of the wire forming the nose pad supports. The nose bridge may be attached directly to eyeglass lenses or to complete or partial frames for the lenses.

Abstract: A sliding bridge eyeglass frame provides salespersons and customers the ability to insure that a proper interpupillary distance between telescope oculars is achieved during a fitting session. The demonstration frame device of the present invention includes first and second bridge portions which are slidably and reversibly fixedly attached to thus allow a customized fitting for particular customers. Once proper interpupillary distances are achieved, the first and second frame members are secured together such that proper dimensions and configurations can be obtained for production of a final product.

Abstract: An eyeglass frame having first and second rims for receiving lenses, temple pieces for positioning the frame over the user's eyes, and a first resilient bridge. The first bridge is coupled between rims and has first and second cables for allowing the rims to pivot about the first bridge between an original position and displaced positions while biasing the rims toward the original position. Each of the cables is rigidly coupled between the rims and formed by multiple strands that are spirally-wrapped around each other. The cables are adjacent one other and spirally-wrapped in opposite directions. The first bridge can include a rotating bar for added stability. The eyeglass frame can also have a second bridge formed of a flexible bar or of at least one cable that has multiple strands that are spirally-wrapped. The second bridge can be a single cable with or without a protective cover, or multiple cables that are spring-biased towards each other.

Abstract: The present invention relates to an eyeglass frame having a tightening portion disposed in the middle of an NT alloy loop wire 6, and the outer peripheries of a pair of right and left rims, which are disposed inwardly of the loop wire, tightened and secured in position by the tightening portion. With this arrangement, an eyeglass frame having increased strength can be obtained and a wide variety of parts can be prepared to meet the various demands of users.

Abstract: Molded eyeglasses, including two rimless molded lenses with a plastic material bridge having end portions which are molded into and embedded in the molded lenses. The invention is useful for pince-nez or normal eyeglasses. The bridge end portion is completely surrounded by lens material.

Abstract: Disclosed herein is an eyeglass frame member comprising a predetermined length of a rod-like material made of an alloy of super elasticity and shape-memory property, said material having a predetermined number of thin portions of a reduced diameter, the thin portions disposed at desired intervals at both sides of a middle section of said rod-like material, wherein connecting pieces made of a higher solderable metal are respectively fitted in or wound around the thin portions, the middle section being formed into a bridge, intermediate sections to which the connecting pieces are fixed being simultaneously formed into eyebrow portions to which rims for holding respective lenses are to be fixed, and end sections of the rod-like material being bent to form lugs extending rearwards.

Abstract: An eyeglass frame is disclosed which comprises a monolithic, one piece front member fabricated of thermoplastic resin and having a unitary brow bar and a pair of lens rims depending therefrom, there being an elongated reinforcement member fully embedded within said front member.

Abstract: A metallic eyeglass-frame, in particular its each bow has a core-to-covering structure in which high silver or gold-content covering is clad to the surface of a super elastic core made of Cu-Sn-Zn, Cu-Al-Zu or Cu-Al-Ni alloys in order to reduce plastic deformation during use and assure high work ability in production, thereby allowing the eyeglass-frame to constantly rest stably on the wearer's facial construction with no increase in uncomfortableness and fatigue on the wearer.
