Abstract:
A novel frame construction for eyeglasses is provided wherein the upper frame member is formed to have greatly enhanced flexibility to increase the overall adjustability, comfort and fit of the eyeglasses. The upper frame member includes areas wherein the material is selectively weakened to create predetermined flex points periodically within the frame member. Additionally, the weakened areas may be filled and/or covered with a second material that is more flexible than the base material used to form the frame member. The enhanced flexibility allows the upper frame member to flex as the temple members of the eyeglasses are stretched outwardly providing a comfortable fit for a wide range of wearers. Further, the top edge of the eyeglass lens may include formations that provide clearance for the deflection of the top frame member.
Abstract:
A novel hinge assembly for eyeglasses is provided wherein a first structural member for the hinge structure is formed in a first molding step and a second structural member of the hinge structure is formed directly over a portion of the first structural member in a second molding step. The present invention utilizes in-mold-assembly techniques to reduce the assembly steps required to form such a hinge assembly while further resulting in a hinge assembly that has increased adjustability and utility. Specifically, the overmolded components form a ball and socket type joint allowing a large degree of lateral rotation in one direction and a limited amount of freedom in a second direction. This hinge allows the temple portion of the eyeglasses to be folded against the brow bar and the inclination angle between the temples and the brow bar to be adjusted.
Abstract:
A kind of resilient hinge for spectacle frames and a method of manufacturing same. Said resilient hinge includes at least an axis as well as a positioning guide, a resilient medium and a stopper, which are fitted over and through the axis in the aforesaid order. The spectacle frame front and temple can be correspondingly closed and opened conveniently and smoothly through the resilience generated by the resilient hinges provided between the spectacle frame front and the temple. The positioning guide is thus designer to maintain the stability of this process. Said method should at least include the following steps: to make the axis into its basic form from a metal sheet; to reduce the diameter size of the end portion of the said axis bearing the basic form and process it into a cylindrical shape with a specified diameter; a hole is provided at the top end of the axis to form a hinge hole. The axis formed will have a high level of brightness without any traces of pressing marks on its surface, the smooth stretching out and bouncing back of the spring is guaranteed. The density of metal molecule is uniform, free from stress concentration. This enhances the hardness, rigidity and stability of the axis. The entire length of the axis can be controlled freely according to structural requirements.
Abstract:
In a pair of glasses, in particular industrial safety glasses, comprising a frame with side pieces which are articulated thereto by a side-piece projection; and two eyeholes with encircling grooves and sight pieces inserted in the grooves; the frame being divided in the vicinity of the eyeholes for expansion and exchange of the sight pieces and lockable in the closed position; and the frame being divided in the vicinity of the side-piece projection; it is provided that the side-piece projection, in prolongation of the divided area of the frame, is divided into a top projection of the top frame member and a bottom projection; and that a pivoted locking device is pivotably mounted on the top projection of the frame member and lockable in place by the bottom projection.
Abstract:
A hinge connector assembly for securely attaching an earpiece to a frame of a pair of eyeglasses includes a hinge connector and connector clamp which secure an earpiece therebetween. The means for securing the earpiece comprise threaded bores attached to the connector clamp which combine with bolts inserted through bolt holes in the hinge connector. Further, notches located on the hinge connector combine with protruding tabs located on the connector clamp for added support. The hinge connector also includes a hinge element for attaching to a corresponding hinge element located on the frame of glasses.
Abstract:
The eyewear described comprises a lens having, at opposite lateral sides thereof, a pair of detachable ear stems which are adapted to move from an inwardly folded position to an outwardly ear contacting position. The lens displays, at each lateral side, an opening and a stem connecting portion that defines a hinge element forming an integral part of the lens. The proximal end portion of the ear stem defines a U-shaped recess which is engageable with the hinge element. The recess is formed by a pair of resilient branches which, together with a constriction at the entry of the recess, enables a snap-in engagement and a snap-out disengagement of the ear stem to and from the lens. No additional component is required for this three-piece eyewear.
Abstract:
A temple bar assembly for eyeglasses is provided having several adjustable members wherein all of the joints are formed by utilizing in-mold-assembly techniques to reduce the assembly steps required to form such a temple bar assembly. The temple bar assembly includes at least one of the following adjustment points: temple length, inclination angle and/or hinge attachment all formed using IMA while further resulting in a temple bar that has increased adjustability and utility. Also, the materials selected may include either hard or soft plastics to form either component.
Abstract:
A novel nose pad assembly for eyeglasses is provided wherein the support and nose pad are formed as a fully articulating ball and socket joint. The ball and socket joint provides excellent adjustability of the nose pads in a simple mechanical construction. In a unique method of forming the nose pad assembly the support structure (ball) is formed in a first molding step and an adjustable pad member is molded directly over the ball of the support structure in a second molding step. The present invention utilized in-mold-assembly techniques to reduce the assembly steps required to form such a nose pad assembly while further resulting in a nose pad that has increased adjustability and utility. Alternately, the pad portion may be formed first and the support structure formed second. Also, the materials selected may include either hard or soft plastics to form either component.
Abstract:
Eyeglasses includes a frame including right and left portions each including a recess abutted on a bridge, a projection on an endpiece, and an aperture proximate the projection. The eyeglasses further includes two lenses each including an indentation at an outer end and a hole proximate the indentation, two temples, and two connecting mechanisms pivotably coupled to both the temples and the frame. Each connecting mechanism including includes a pin projected from an inner side. The hole is aligned with the aperture. The indentation is engaged with the projection. An inner end of the lens is rested on the recess. The pin is inserted into the hole and the aperture for fastening each lens onto the frame. The original lenses can be easily changed with other lenses having a different color and/or shape by replacement as long as such lenses have the same specifications as the original lenses.
Abstract:
The invention relates to a joint structure of an eyeglass frame and temples. A joint base on the inside end of the temple is joined to a horizontal dividing face, and a joint on the horizontal dividing face then is engaged with an upper and lower joint holder on either end of the frame, then a screw fixture is used to complete the movement assembling, and thus preventing both temple ends from touching a lens when the temples are folded inward.
