Abstract: A hinge for eyeglasses has a first and a second frame part, the parts being joined in an articulated manner by a spindle element, the end of the first frame part having a bend which encloses at least in part the spindle element in a pivoting manner, wherein the bend of the first frame part forms two vertically spaced closed loops of a first diameter. The second frame part has a through hole of a second diameter and is positioned in the space between the two loops, such that the first frame part and the second frame part are swivelably connected by the spindle element, which reaches through both the loops and the through hole.

Abstract: A pivot-axis, pin arrangement for rifle receivers can serve as a trigger or hammer pin therefor. A lower housing has a pair of sidewalls defining a gap and with a pair of bores spaced across the gap. The outer side of one sidewall has a slightly recessed channel which is elongated between spaced ends, at least one of which is rounded and centered on the axes of the spaced bores. The pivot axis pin has a cylindrical shaft and a T-slot head style head. The head has one portion forming an annular ring while the remaining portion is elongated to an end. In use, the pin is inserted through the bores, and is ‘simply supported’ by the ends thereof in the bores therefor. The head of the pin locks against rotation merely by settling in into at least one rounded end of the recessed channel.

Abstract: A rim locker for spectacle frame comprises a first portion and a second portion which are connected to two edges of lens rim in cut-off position respectively. The second portion has a screw hole for inserting a screw and the first portion is having thread to let the screw in for fastening the lens rim. The screw further has a stopping cap and the first portion further has a cylinder housing for hiding and moving the stopping cap, so that when the rim-locker is opening, the stopping cap will moving along the track of the housing, and stop at the end to prevent the screw slip off from the rim-locker and protect the screw threads not strip off easily.

Abstract: The present invention provides an eyewear frame assembly. A frame has an aperture for receiving a lens. The frame has a split to expand upper and lower portions of the frame to insert or remove the lens from the aperture. First and second projections extend outwardly from the upper and lower frame portions, respectively. The first and second projections have first and second tapered portions, respectively. A sleeve receives said first and second projections. The sleeve has first and second inwardly extending and tapered tabs adapted to receive the first and second tapered portions to secure the first and second projections within the sleeve. The upper and lower portions of the frame are prevented from expanding when the first and second projections are received within the sleeve. First and second openings in the sleeve provide access to depress the first and second projections to remove the first and second projections from the first and second sleeves.

Abstract: An eyeglass assembly and coupling system is assembled by an upper half frame, a lower half frame, a pair of lenses and a pair of temples. The characteristic lies in that the upper half frame is provided with an upper hollow in the bridge portion, a flanged portion is formed at each side of the upper hollow, an elongated groove is provided at one side of each flanged portion, and each flat end of the upper half frame is provided with a screw hole. The lower half frame is provided with a flanged block at the bridge portion, a lower hollow is formed at each side of the flanged block, an elongated groove is provided at one side of each lower hollow, and each flat end of the lower half frame is provided with a screw hole.

Abstract: The protective eyewear assembly described comprises a frame having right and left portions defining respective right and left apertures and a central bridging portion, and a protective lens piece adapted to be mounted to the lens piece between the upper and lower edges of the frame. The lower edge of the frame has a retaining wall for retaining the lens therein while the upper edges of the frame and the lens piece have cooperating portions to secure the lens to the frame. The frame may be made of flexible plastic material to enable a snap-in engagement and a snap-out disengagement of the lens to and from the frame.

Abstract: Eyeglasses and clip-ons are improved by providing housings for magnets for securing the clip-ons in a uniblock also incorporating one or more of the following: part of a closing block, an end piece, and part of a hinge. The structure is more compact, neater in appearance, and of improved quality as compared to eyeglasses incorporating conventional structures, and is less expensive to manufacture than many conventional eyeglasses, especially in large volume.

Abstract: A spectacle frame includes one or more frame members for receiving lenses and having an intermediate bridge portion and each having a temple portion. The bridge portion and the temple portions each has or each is formed with a pair of extensions. A clamping device is engaged onto or pivotally coupled to each pair of extensions for forcing the extensions toward each other and to retain the lenses within the frame members. The lenses may be engaged easily into or disengaged from the frame members when the clamping devices are disengaged from the extensions.

Abstract: An eyeglass frame has a pair of at least limitedly flexible upper arms and a pair of respective at least limitedly flexible lower arms. Each arm has an inner end and an outer end and a bridge interconnects the inner ends so that each upper arm forms with the respective lower arm to a respective side of the bridge a seat for a lens. Respective pairs of elastically deformable elements have front ends fixed to the outer ends of the arms and rear ends fixed to a respective temple support with each pair of elements biasing the respective upper and lower arm toward each other so that the lens is gripped elastically in the seat. A respective temple is pivoted on each of the temple supports. A pair of eyeglasses is assembled from such a frame and a pair of lenses by first displacing each upper arm away from the respective lower arm with elastic deformation of the respective elements until the respective seats are wide enough to accept a respective lens.

Abstract: Disclosed is an improved structure for coupling some selected parts of a pair of glasses, particularly for fixing a lens to an associated rim and at the same time, the rim to the joint piece, to which one or the other temple is hinged. The rim has a loop hole at its outer side, dividing the rim circumference into upper and lower rim halves. The rim has two broach sections fixed to the opposite ends of the upper and lower rim halves, and the joint piece has a hollow coupler member to permit the broach sections to be press-fitted therein, thereby holding the lens inside the rim. Two catch pins are fixed to the inner sides of the adjoining rims. These catch pins are inserted into the lateral holes of the opposite ends of the bridge, thus detachably connecting the bridge to the adjoining rims.

Abstract: A spectacle assembly includes a spectacle frame for holding a pair of corrective lenses, the frame having left and right eyewires for mounting lenses. The eyewires are partially split into two portions to enable replacement of a lens. A right and left connector element is used to clamp together the two portions of the right and left eyewires in order to secure the lenses and to attach left and right temple stems to the spectacle frame.

Abstract: This frame, comprising for each of the lenses to be supported an open metallic eye-piece and of which the ends are adapted to abut one against the other by means of a mutually screwing member is characterized in that the two ends of the metallic eye-piece cooperate with a common guiding groove provided in a connecting lug so that, by relative engagement of its ends in the groove, they are perfectly aligned one in the extension of the other.
