Abstract:
The disposable safety eyewear has a lens portion having a bridge portion and a nose support thereon. Left and right temple bars are connected to the lens portion by living hinges. The living hinges are operable between an open position and a folded position. Mating formations secure the living hinges in its respective folded position.
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 system for heating the sound-reflective mirror surface of a phased array monostatic sodar apparatus. The system has a heat source located at a position that is spaced from the mirror, a control system that controls the operation of the heat source, a working fluid that is heated by the heat source and used to transfer heat from the source to the mirror, and a delivery system that constrains the heated working fluid and delivers it from the heat source to the mirror.

Abstract:
A brow bar and lens assembly for eyeglasses is provided wherein a flexible brow bar member is attached to a lens assembly only along a central region. By attaching the lens and brow bar in this manner, the brow bar is allowed to flex relative to the lens thereby providing additional means for adjusting the width of the eyeglasses and increasing the comfort for the wearer. Further, the lens construction may include channels along its top edge thereby creating voids that provide a space into which the two ends of the brow bar can travel when deflected relative to the central region.
Abstract:
A frame assembly for eyeglasses is provided wherein the overall width of the eyeglass frame is adjustable by utilizing a telescoping brow bar. The upper frame member or brow bar is formed to include either a pair of telescoping or indexed joints allowing the length of the brow bar to be adjusted thereby placing the hinge points and temple bars further apart from one another. The adjustable length of the brow bar provides excellent adjustability of the overall width of the eyeglass frame in simple mechanical construction. Further, in a unique method of forming the adjustable brow bar assembly a central portion may be formed in a first molding step and an adjustable hinge section is then molded directly over the central portion in a second molding step. The present invention utilizes in-mold-assembly techniques to reduce the assembly steps required to form such an adjustable brow bar assembly while further resulting in an eyeglass frame that has increased adjustability and utility.
