Description

Lens changing structure of glasses

Technical Field

The present invention relates to a lens-changing structure of eyeglasses, and more particularly to a lens-changing structure of eyeglasses which can be pressed to position a lens or can be separated from an eyeglass frame.

Background

A pair of conventional eyeglasses generally includes a frame, two lenses and two temples pivotally connected to two sides of the frame. Two caulking grooves are arranged at the inner side of the rim of the spectacle frame for combining the two lenses. When assembling each lens, the lens must be forced into the insertion groove by matching the elasticity and pressing manner of the material. However, since the lenses are often fragile, the lenses may be damaged or the frame may be damaged when the lenses are attached or detached.

In the prior art, although there are various glasses with removable lenses, the lenses can be easily replaced without damaging the lenses and/or the frame; for example, taiwan patent publication No. M496142, discloses glasses with replaceable lenses, which comprises: a frame including a first end and a second end longitudinally spaced apart from each other, the first end and the second end of the frame each having a connecting base, each connecting base including an inner end and an outer end longitudinally spaced apart from each other, the inner end of each connecting base being provided with a lens supporting groove, each connecting base further including an outer surface, an inner surface, and a through hole extending from the outer surface through the inner surface, the outer surface being provided with a guide groove extending in the longitudinal direction; at least one lens which is assembled in the lens supporting groove of the lens frame and comprises a side part which can be correspondingly combined in the lens supporting groove of the connecting seat, wherein the side part is provided with a notch which is aligned with the part of the through hole of the corresponding connecting seat; the front end of each glasses leg is pivoted with the outer side end of the connecting seat of the glasses frame, so that each glasses leg can rotate between an unfolding position and a folding position relative to the glasses frame; the body is accommodated in the guide groove of a corresponding connecting seat, and the column extends through the through hole of the corresponding connecting seat and can move between a first position and a second position along the longitudinal direction; when the column body is at the first position, the column body is inserted into the gap of a corresponding lens to be combined; when the column body is at the second position, the column body is separated from the notch of the corresponding lens; when the glasses leg is at the unfolding position, the column body of the push button can not move from the first position to the second position; when the temple is at the folding position, the cylinder of the push button can move between the first position and the second position.

Or taiwan patent publication No. M487450, which comprises: a mirror frame, a caulking groove is arranged below the mirror frame, an inner concave joint part is arranged in the center of the mirror frame, and a buckle groove is arranged in the front and back direction of the joint part; a lens, which is in a single piece type, the top edge of the lens can be embedded into the embedded groove of the mirror frame, and a concave part is arranged at the position corresponding to the nose part of a human body below the center; a first joint block, which is arranged at the rear of the mirror frame, is provided with a buckling groove and is also provided with a first buckling part which can be buckled with the concave part of the lens; a second joint block, which is arranged behind the first joint block and is provided with a second buckling part capable of buckling the joint part of the picture frame and a buckling body capable of buckling with the buckling groove of the first joint block.

Although the above-mentioned structures can smoothly disassemble or replace the lenses, one of them is a clamping and fixing way with push buttons on both sides, which is time-consuming in operation, and the heads of the push buttons protrude out of the frame and are located at the side of the eyes to obstruct the view and have danger; in addition, the two joint blocks located at the nose bridge are required to be matched and assembled with each other, which is inconvenient in the assembling process, and if the joint blocks are lost in the disassembling and assembling process, the joint blocks cannot be correspondingly assembled and replaced.

Therefore, the inventor takes on the abundant design development and actual manufacturing experience of the related industry for many years, researches and improves the existing structure, and provides a glasses lens changing structure so as to achieve the purpose of better practical value.
