Abstract: Disclosed is an improved frame structure for glasses using two counter joint pieces loosely coupled with a screw. One of these joint pieces is fixed to the rim projection, and the other joint piece is fixed to the temple, and these joint pieces are pulled toward each other under the resilient influence, which is caused by the spring plate of the joint piece on the temple side, thereby assuring the stable folding and unfolding of the temples on the front, still permitting each temple to move a short distance from the 90 degree-wide unfolding or linear-alignment with the rim projection like the "Spring Hinge".

Abstract: Disclosed is an eyeglasses frame using temple joints improved according to the present invention. Each hinge assembly is fixed to the joint piece of either side of the frame. It comprises an engagement piece having an axle transversing in its recess end, and a hollow sheath having a lever pivotally fixed to its open end and a spring-biased slider contained therein. The slider has a hook end. The engagement piece is fixed to the joint piece, and the sheath is fixed to the temple. The temple is connected to the front by inserting the hook of the slider in the recess of the engagement piece, and then the temple is pulled to the engagement piece by the resilient force, which is applied to the slider all the time. Thus, the temple-to-front connection is assured to be tight, still permitting the stable opening-and-folding of the temple relative to the front.

Abstract: The case and stand for use with eyewear having filament-type temple pieces is a rectangular bed defined by a base panel and upwardly extending rigid side panels at the opposite ends thereof. To the upper ends of the side panels leaves are pivotally supported and the tops of the leaves are notched to receive respectively the pairs of strands. The leaves are each provided with earpiece retainers on the outside faces thereof so that the filaments can train over the top of the leaves respectively and the earpieces fit in the retainers, the lenses thereby suspended below. U-shaped covers are pivoted to the outer ends of the base panel so that in one position they can form pedestals for supporting the bed to be a stand, or when the leaves are folded inward can be flipped around to be a two-piece cover for the case.

Abstract: Protective spectacles have a protective shield, fitted in the temple region, to protect the eyes from dust, etc., coming from the side. According to West German Industrial Standards, DIN, a predetermined degree of sealing must be maintained, according to the purpose of use, between it and the spectacle frame. Protective shields attached rigidly to the frame are cumbersome. The protective shield is firmly connected by its upper edge region to the associated spectacle earpiece. It is thus pivoted away together with the earpiece. Its forward edge seals with the spectacle frame with a predetermined degree of sealing. So that this is not impaired by adjustment of the inclination, the earpiece has a bending zone behind the protective shield. The inclination is adjusted by bending the earpiece. The invention may be used for protective spectacles in the industrial and private fields.
