Description

Glasses with interchangeable lenses

The present invention relates to a pair of glasses, and more particularly to an interchangeable lens.

With the improvement of material life, people seeking new and changing things are becoming more and more particular about the decorative items that they carry. In terms of glasses, in order to pay attention to aesthetics and matching clothing, sunglasses or casual glasses are also becoming popular. Since sunglasses or casual glasses focus on fancy and varied changes, users often want to change lenses to match mood and clothing. However, the replacement of lenses for sunglasses or casual glasses is not convenient, causing users to move. Replacing the neat glasses is not economical.

In particular, conventional glasses generally include a frame, two lenses, and two temples pivotally coupled to the sides of the frame. Two slots are provided on the inner side of the frame frame to accommodate the corresponding two lenses. When assembling each lens, it is generally necessary to force the lens into the groove by matching the material elasticity and the hardening method. However, since the lens tends to be brittle, it may cause lens breakage or frame damage when the lens is removed.

In the prior art, although a variety of spectacles having a detachable lens have been produced, the lens can be replaced easily and does not cause damage to the lens and/or the frame. However, the eyeglass structure of the conventionally disassembled lens is generally applicable to a frame having only a half frame (upper half frame), and is not applicable to a frame having a full frame. Thus, the overall shape of the lens is limited and the robustness of the lens to the frame is negatively affected.

Accordingly, it is a primary object of the present invention to provide an eyeglass that provides a user with a convenient replacement of the lens, and which is suitable for use on a frame having a full frame, thereby enhancing the robustness of the lens to the frame.

The eyeglasses of the present invention comprise an upper frame, at least one lens, a lower frame, two temples and two fastening members. The upper frame comprises a longitudinally separated two side ends and a joint seat between the two side ends, the bottom of the joint has a slot, and each side end of the upper frame has a connecting seat, and each connection The inner end and the outer end of the longitudinal partition are disposed, the inner ends of the two connecting bases face the binding seat, and each connecting seat further comprises an outer side surface, the outer side surface is provided with a groove, and the upper frame further comprises at least A lens support slot. The lens includes an upper end and a lower end. The upper end of the lens is coupled to the lens support slot of the upper frame. One end of the upper end of the lens is provided with a fastening hole adjacent to an inner end of a corresponding connector. The lower frame includes an intermediate portion between the two sides of the longitudinal partition and an intermediate portion between the two side ends. Each side end of the lower frame extends upwardly with a first joint portion, and each first joint portion of the lower frame Inserting into a groove of a corresponding connecting seat of the upper frame, so that the two side ends of the lower frame are detachably coupled with the two side ends of the upper frame, and the middle portion extends upwardly with a second joint, the second The joint is inserted into the slot of the joint of the upper frame for bonding. Each of the temples includes a spaced apart front end and a rear end, and the front end of each of the temples is coupled to an outer end of a corresponding connector of the upper frame. Each of the fastening components includes a first end and a second end. The first end of each of the fastening components is provided with a fastening portion, and the second end of each fastening component is coupled with a corresponding mirror. The upper frame is moved between a fixed position and a separated position. When the fastening members are in the fixed position, the fastening portion is inserted into the fastening hole of the lens, and each fastening component covers one of the lower frames. The first joint portion is separated from the fastening hole of the lens when the fastening members are in the separated position.

In one embodiment, the upper end of the groove of each connecting seat extends inwardly, and a first hook portion is formed on the upper end of each of the first joint portions, and the first hook portion is engaged with the concave portion of the corresponding connecting seat. A joint hole is disposed in the inner portion of the joint, and the joint hole communicates with the slot. The upper end of the second joint portion forms a second hook portion, and the second hook portion is engaged with the joint hole of the joint seat.
