Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, specifically to a frameless eyeglass that is easy to assemble and disassemble. Background Technology

[0002] Eyeglasses play an important role in daily life, such as providing vision correction glasses (for nearsightedness, farsightedness, and reading glasses) and protecting the eyes with sunglasses and swimming goggles. Most conventional eyeglasses are framed. To ensure structural strength, frames are typically made of metal or thick polymer plastics, resulting in a heavier frame. This makes framed eyeglasses quite heavy, less convenient to wear, and prone to causing fatigue on the bridge of the nose with prolonged use. Therefore, rimless eyeglasses have emerged on the market.

[0003] Currently, most rimless eyeglasses still use hinges and screws to connect the temples and bridge to the lenses. This design has several problems: it involves many parts, leading to long assembly times and low efficiency; furthermore, disassembling or assembling the temples, bridge, and lenses requires a specialized screwdriver, and improper operation can cause the lenses to crack at the mounting holes, even rendering them unusable; and it limits the flexibility of lens replacement. Therefore, this invention proposes a rimless eyeglass design that is easy to assemble and disassemble, aiming to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technology and provide a frameless eyeglasses that is easy to assemble and disassemble. The temples are fitted into the insertion holes on the lenses via a connector at the front end, and similarly, the bridge is fitted into the insertion holes on the lenses via connectors at both ends. Compared to the method of connecting the temples and bridge to the lenses via hinges and screws, this invention effectively reduces the number of parts. The temples, bridge, and lenses can be assembled into eyeglasses by hand, which is simple to operate and quick, greatly improving the assembly and processing efficiency of frameless eyeglasses. The temples or bridge can also be pulled off the lenses by hand to flexibly select lenses with the appropriate prescription and color, significantly improving the usability of frameless eyeglasses.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a frameless eyeglass that is easy to assemble and disassemble, including lenses, temples, and a bridge. The lenses are provided with insertion holes at both ends. The temples are hinged to the front end with a post. The front end of the post has a first insertion connector. The bridge is provided with second insertion connectors at both ends. The outer peripheral surfaces of the first and second insertion connectors are provided with anti-slip textures. The temples are tightly fitted into the corresponding insertion holes at the left or right end of the lenses through the first insertion connector at the front end. The bridge is tightly fitted into the corresponding insertion holes at the left or right end of the lenses through the second insertion connectors at both ends.

[0006] This utility model discloses a frameless eyeglasses that is easy to assemble and disassemble. The temples are fitted into the insertion holes on the lenses via a connector at the front end. Similarly, the bridge is fitted into the insertion holes on the lenses via connectors at both ends. Compared to the method of connecting the temples and bridge to the lenses via hinges and screws, this design effectively reduces the number of parts. The temples, bridge, and lenses can be assembled into eyeglasses by hand, which is simple and quick, greatly improving the assembly efficiency of frameless eyeglasses. The temples or bridge can also be pulled off the lenses by hand to flexibly select lenses with the appropriate prescription and color, significantly improving the usability of frameless eyeglasses.

[0007] The preferred technical solution is that the insertion hole on the lens is a longitudinal waist-shaped hole, and the first and second insertion connectors are both "n"-shaped insertion connectors that are adapted to the longitudinal waist-shaped hole. The post head is a "Z"-shaped rod structure. The first insertion connector is formed by bending the front end of the post head 180°. The left and right ends of the middle beam are respectively provided with downward bent support arms. The middle part of the support arm is bent towards the lens side to form the second insertion connector. The lower end of the support arm is equipped with a nose pad. Both connector 1 and connector 2 are designed as "n"-shaped connectors that are compatible with the longitudinal waist-shaped holes on the lens. This provides a good anti-rotation effect when connector 1 and connector 2 are inserted into the longitudinal waist-shaped holes on the lens, ensuring the overall stability of the rimless glasses. When the rimless glasses are opened from a folded state to an unfolded state, the tension on the temples that is opened to the left and right sides can be well distributed on the lens body, effectively preventing connector 1 from slipping out of the insertion hole on the lens. At the same time, it effectively prevents the lens from cracking due to localized stress at the insertion hole position, ensuring the safety of the rimless glasses of this utility model during use.

[0008] A further preferred technical solution includes a rotating shaft assembly. The rotating shaft assembly has an upper annular groove and a lower annular groove on its outer peripheral side. The rear end of the post is embedded and welded into the side of either annular groove one or annular groove two facing away from the lens. The front end of the temple has a bent ring body, which rotates and fits into the other annular groove one or annular groove two on the rotating shaft assembly. The rear end of the post also has a bent limiting section for limiting the temple to a perpendicular position to the lens. The installation method of the rear end of the post and the front end of the temple on the rotating shaft assembly is ingenious and reasonable, ensuring smooth folding or unfolding of the temple. Simultaneously, the limiting section at the rear end of the post limits the opening of the temple, effectively preventing excessive opening of the temples and ensuring good clamping force on the user's cheeks, thereby further improving the safety and comfort of using the frameless glasses of this invention.

[0009] A further preferred technical solution is that the rotating shaft assembly includes a stud, an internal threaded sleeve, and a washer. A top plate is vertically fixed to the upper end of the stud, and a bottom plate is vertically fixed to the lower end of the internal threaded sleeve. The lower end of the stud is screwed into the interior of the internal threaded sleeve. The washer is fitted onto the stud, and the washer, stud, and top plate together form an annular groove one, while the washer, internal threaded sleeve, and bottom plate together form an annular groove two. The rotating shaft assembly has a clever and reasonable structural design, ensuring the smooth fabrication and implementation of the frameless glasses of this invention.

[0010] A further preferred technical solution includes an open ring body two bent at the lower end of the support arm, a mounting post on the nose pad, and an circumferential groove on the outer periphery of the mounting post near the nose pad. The nose pad is engaged with the open ring body two at the lower end of the support arm via the circumferential groove. The nose pad is easy to install and remove at the lower end of the support arm, allowing for flexible replacement and ensuring comfort when wearing rimless glasses.

[0011] A preferred technical solution is that both connector one and connector two are inserted into the corresponding insertion holes on the lens from back to front. The assembly method of connector one and connector two with the lens is reasonable, ensuring the comfort of wearing the rimless glasses, and effectively distributing the lateral force when the temples are open onto the lens, which helps extend the lifespan of the rimless glasses, and also improves the overall aesthetics.

[0012] A further preferred technical solution is that the temples are made of titanium, while the headpiece and bridge are made of stainless steel. Titanium temples offer good flexibility and are lightweight, while stainless steel headpieces and bridge offer good hardness and corrosion resistance, ensuring the overall stability, portability, and flexibility of the rimless glasses of this invention.

The temples, bridge, and lenses can be assembled into eyeglasses by hand. The operation is simple and quick, which helps to greatly improve the assembly and processing efficiency of frameless eyeglasses. The temples or bridge can also be pulled off the lenses by hand to flexibly select lenses with the appropriate power and color, which significantly improves the usability of frameless eyeglasses.

[0015] 2. Both connector one and connector two are designed as "n"-shaped connectors that are compatible with the longitudinal waist-shaped holes on the lens. This provides a good anti-rotation effect when connector one and connector two are inserted into the longitudinal waist-shaped holes on the lens, ensuring the overall stability of the rimless glasses. When the rimless glasses are opened from the folded state to the unfolded state, the tension on the two temples that is opened to the left and right sides can be well distributed on the lens body, effectively preventing connector one from slipping out of the insertion hole on the lens.
