Abstract: Eyewear is provided, namely, sunglasses with an integral securing mechanism that enables the lenses to be removed and replaced as necessary. Each of the lenses may retained within the frame of the eyewear/sunglass device as by corresponding channels or recesses formed on each corresponding side of the sunglass frame. For separate lenses, a securing mechanism is provided for securing each of the lenses. In a mono lens configuration, a single securing mechanism may be used to secure both lenses. A securing mechanism is placed in a locked position to hold the lens(es) in place during use. The securing mechanism is placed in an unlocked position by sliding or shifting the securing mechanism, enabling removal of the lens(es). Various constructions can be adopted for maintaining the securing mechanism in the locked position, such as by frictional force, magnetic force, or combinations thereof.

Abstract: The present invention provides an eyeglass frame securement apparatus comprising an eyeglass frame with upper and lower frames for eyeglasses to be mounted thereon, two outer sides of said upper and lower frames attached to eyeglass temples, a protection strip frame locked into inner circumference of said eyeglass frame; protruding pins extending forward and rearward from a center of the lower frame pivotally attached to the upper frame; a rib extending from outer sides of the upper frame and inserted into grooves to restrict the eyeglasses; protrusions on upper end of supporting shaft of the eyeglass temples inserted into the spaces on the outer side of said lower fame. Therefore, once the upper frame is completely assembled, said eyeglass temples can be outwardly bent to allow said protrusions on the upper end thereof to extend outward from the horizontal hole of the upper frame to restrict said eyeglass temples directionally.

Abstract: Eyeglasses with replaceable lenses include a lens frame, two lenses, two temples jointed pivotally with two ends of the lens frame, and two fastening members. The lens frame has two through holes respectively embedded with the lenses. The through hole has an embedding groove and a blocking projection. The lens frame also is also provided with a combining surface, used to engage with the fastening member, located at two sides respectively and having a notched portion next to the through hole. The fastening member possesses a locking portion with a locking groove at the top and a locking projection located at one side of the bottom for interlocking with the fixing groove. So a user can easily change lenses without utilizing any tool, in accordance with diverse occasions or fondness.

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: A lens frame for spectacles, wherein an elastic segment is disposed between a pair of assembling pieces which are formed at both free ends of the lens frame, with the free ends defining an assembling region. When lenses are fitted into the lens frame, the pair of assembling pieces and the elastic segment are clamped together by a screw which passes therethrough.

Abstract: To avoid excessive stressing of lenses and still facilitate the attaching and removing of the lens to the rim, a pair of eyeglasses has an improved rim lock member. The rim lock member has a two-parallel wire arrangement and a metal piece slidably movable thereon. The opposite ends of the loop hole of each rim are connected to the two parallel wire ends, and the space of the loop hole can be controlled by moving the metal piece on the two-parallel wire arrangement. Specifically the loop hole of each rim can be reduced by moving the metal piece toward the rim on the two-parallel wire arrangement until the circumferential length of time rim is shortened to wind tightly around the lens, thereby holding the lens fixedly. The bridge of the front of a pair of rimless eyeglasses has a similar parallel wire-and-metal assembly structure.

Abstract: A lens coupling structure couples a bridge or a temple to a lens of rimless eyeglasses. A bridge or a temple is coupled through a flanged bush to the lens which is formed with a screw hole and a recess. The coupling portion of the bridge or temple and the flanged bush are formed with a screw hole. A fixing screw extends through the bridge or temple, the flanged bush and the lens. The flanged bush has a flange and a cylindrical portion received in the hole formed in the lens. The corresponding portion of the bridge or temple has a protrusion adapted to be received in a recess formed in the flanged bush. The protrusion may be provided on the fixing screw or a seating plate mounted between the flanged bush and the bridge or temple.

Abstract: An eyeglass frame has rims or surrounds at least locally made from a relatively rigid material. They have in transverse cross-section over at least part of their length a U-shape profile with a median part and side flanges. A strip of relatively flexible material is associated with each rim or surround and is disposed between it and the respective lens. The median part of the profile of the rims or surrounds has an increased thickness in its median area.

Abstract: This disclosure refers to the securing of lenses in an ophthalmic mounting having a split rim eyewire using a spring loaded connecting device.

Abstract: An eyeglass frame having removable lenses, comprising of lens rings which are split into an upper and lower ring portion. Interposed between the upper and lower ring portions, and forming an integral part of the frame and positive actuating means to force open and draw closed the split lens rings to facilitate insertion and removal of lens. Several spices of eyeglass frame are visualized The preferred spieces utilizes a coil spring and resilient rod. Another spieces visualized utilizes several serrated coupling edges and an actuating fulcrum.

Abstract: The invention relates to a device for fixing lenses in the bezel rims of a spectacle frame, allowing easy and repeated mounting and removal of these lenses on to and from the frame. The bezel of the frame rim has a concave polyganol shape in cross-section. A metal ring sets the lens definitively round its periphery and has a rounded convex external edge. As viewed in cross-section, the contact between this external edge and the bezel is therefore made at points when the ring/lens assembly is fitted in the bezel rim.

Abstract: Eyeglasses of a type which permit interchanging of lenses are disclosed which employ a collapsible frame having a pair of hingedly interconnected lens-mounting portions. The lens-mounting portions are configured to engage the peripheral edge of the lens and include several prongs. The peripheral edge of the lenses include prong-receiving recesses which position the lenses relative to the frame to provide secure mounting thereto. The lens-mounting portions of the frame also include a separable connection wherein a mounting lug mounted to one part of the section is received in a socket formed at an end of an opposing section. The separable connection allows the lens-mounting portions to open, facilitating mounting and removal of the lenses, and close so as to provide secure mounting of the lens relative to the frame.
