Description

Title

Spectacles

Background of the Present Invention

Field of Invention

The present invention relates to spectacles, and more particularly to a rimless spectacles, wherein a plurality of coupling slots are located at the lenses to engage with the temples and the bridge, so as to allow the lenses to be quickly fastened on the temples and the bridge to form an entire body structure of the rimless spectacles.

Description of Related Arts

Corrective lens have been existed in human history for a long time. People have used corrective lens to modify the focal length of the eyes and the corrective lens have gradually evolved to wearable glasses. Wearable glasses have been more widely used in modern society. Conventional glasses comprise a lens unit mounted at a frame unit. The frame unit usually comprises a frame, two temples and a bridge. Traditionally, the frame, the temples and the bridge are made integrally to form the frame unit. In other words, the frame, the temples and the bridge are all connected altogether in conventional spectacles, wherein each temple is fastened by a screw to an outer side of the frame.

The main purpose for people to wear spectacles is to correct vision or protect the eyes. Also, since spectacles are usually placed on the faces of people, people have even higher demands on the aesthetic value of the spectacles. As illustrated above, the frame is an indispensable component of the spectacles and the frame is usually adapted to secure the lens unit. Also, the conventional frame of the spectacles is usually made of metal materials or other stiff materials. So, when people wear spectacles, existence of the spectacle frame usually change the person's appearance on the face which is also a shortcoming of conventional spectacles. With development of the society, more and more varieties extend from the conventional spectacles, such as rimless spectacles. Structurally, the rimless spectacles comprise lenses, temples, and a bridge directly connecting two lenses, wherein more than one connection holes are on each lens, such that the temples and the bridge are connected at the connection holes respectively. Generally speaking, the lens is made by glass materials, especially for near-sighted and farsighted spectacles. Furthermore, the thickness of the lens in the middle is different from that on the side. In other words, the surface of the lens of either near-sighted or farsighted spectacles is not a flat surface, and the difficulty of drilling holes thereon is thus increased. Normally, when drilling the holes on an object, the drilling device has to be perpendicular to the surface to be drilled to achieve the best drilling effect. In addition, the stiffness of glass materials is high and drilling holes thereon is likely to cause the glass material to break.

In addition, the tolerance of the hole must be considered. If the hole is too big, the lens will be unstable after the temples and the bridge are mounted thereto. If the hole is too small, the temples and the bridge cannot be affixed thereto. Or the lens will be cracked when the temples and the bridge are forced to affix to the lens.

With the difficulty in drilling holes on the lens mention above, it is inconvenient for customers to purchase rimless spectacles because when one chooses his or her own rimless spectacles, the lenses and the spectacle frame are separately chosen by the customer and put together by a technician. Because of the difficulty in drilling holes on an uneven lens surface, the technician usually takes longer time to put the lenses and the spectacle frame together. In other words, the customer has to wait for a long time from choosing the spectacles to actually receiving the final product.

Improved rimless spectacles are found in the market that the rimless spectacles do not require any hole predrilled on the lens. The lens has a notch preformed at the peripheral edge to fit a core-wire at the notch. Therefore, the temples and the bridge can be mounted to the lenses through the wires. However, such rimless spectacles can be made only in particular styles of lenses and the assembling operation is relatively complicated. Summary of the Present Invention

A main object of the present invention is to provide a pair of spectacles, wherein the rimless spectacles are manufactured by a unique method to provide a special connection way to connect the lenses and the spectacle frame.

Another object of the present invention is to provide the spectacles, wherein each of the lenses thereof comprises two first connectors corresponding to second connectors at the temple units and the bridge, such that the lenses can be fastened on the temple units and the bridge via the first and second connectors.

Another object of the present invention is to provide the spectacles, wherein it is not necessary to drill any hole on the lenses, so the difficulty in manufacturing is reduced and the manufacturing efficiency is thus increased.

Another object of the present invention is to provide the spectacles, wherein when a customer purchases the spectacles, he or she can receive the final product quickly due to special manufacturing and connection design of rimless spectacles in the present invention.

In order to accomplish the goal of the present invention, the spectacles comprise:

two lenses, each of which has a front side, a rear side, and a peripheral edge which is defined between laterals of the front and the rear sides;

a frame comprising two temple units and a bridge;

a connection unit comprising a plurality of first connectors provided at the peripheral edges of the lenses respectively and a plurality of second connectors, which are located at the two temple units and the bridge to detachably couple with the first connectors respectively, wherein the two temple units are coupled at two outer sides of the lenses respectively and the bridge is coupled at two inner sides of the lenses respectively, such that the frame is assembled with the lenses by detachably coupling the second connectors with the first connector to form the rimless spectacles.

Detailed Description of the Preferred Embodiment

Referring to Fig. 1 to Fig. 4 of the drawings, a rimless spectacles according to preferred embodiment of the present invention is illustrated, wherein the rimless spectacles comprises two lenses 10. Each of the lenses 10 has a front side 11, a back side 12, and a peripheral edge 13 located between the laterals of front and the rear sides 11, 12. A plurality of first connectors 20 of the connection mechanism are spacedly provided at the peripheral edges 13 of the lenses 10 respectively at the inner and outer sides of each of the lenses 10.

The rimless spectacles further comprise a frame which comprises two temple units 2 and a bridge 3. The temple units 2 are arranged to correspondingly couple with two outer sides of the lenses 10 respectively, and the bridge 3 is adapted to couple with two inner sides of the lenses 10 respectively.

The rimless spectacles further comprises a plurality of second connectors

30A of the connection mechanism provided at the temple units 2 and the bridge 3 respectively, wherein the second connectors 30A are detachably engaged with the first connectors 20 at the lenses 10 to couple the temple units 2 and the bridge 3 with the lenses 10 to form the rimless spectacles without any tool.

As shown in Fig. 3, each of the first connectors 2OA is a coupling slot 20 indently formed at the peripheral edge 13 of the respective lens 10 to define two spaced apart opening edges 21 at the peripheral edge 13 and an opening 211 between the opening edges 21.

More specifically, the coupling slot 20 has two side surfaces 22 and an enlarged arc surface 23 extending therefrom to form a coupling groove 25, wherein the two side surfaces 22 are facing toward each other and are inwardly extended from two opening edges 21 respectively. The distance between the two side surfaces 22 is larger than the distance between the two opening edges 21 such that the width of the opening 211 is smaller that the distance between the two side surfaces 22.

The arc surface 23, which is integrally extended from the two side surfaces 22 respectively, defines a curved contacting surface 24, wherein the coupling groove 25, which is the coupling slot 20, is defined within the two side surfaces 22 and the curved contacting surface 24.

Since the coupling slot 20 in the present invention is continuous channel defined by two opening edges 21 which are inwardly extended, such that it is unnecessary to drill any hole on the lenses 10 in the present invention. Technicians can easily cut at the peripheral edge 13 inwardly to form two side surfaces 22 and the arc surface 23 to form the coupling slot 20. The distance between the two side surfaces 22 equals to the width of the opening 211. In other words, the two side surfaces 22 are extended in a parallel manner.

As shown in Figs. 1 to 4, each of the second connectors 30A comprises a connecting member 31 A and a clipping member 32 A, wherein the connecting members 31 A are provided at the temple units 2 and the bridge 3 respectively. Each of the connecting members 31 A comprises a retention inserter 31 IA and a coupling shaft 312A, wherein the retention inserter 31 IA has a shape and size corresponding to the shape and size of the respective coupling slot 25. Each of the retention inserters 31 IA has a retention surface 31 HA and a biasing surface 3112A, wherein the retention surface 31 HA is shaped and sized corresponding to the curved contacting surface 24. When the retention inserter 31 IA is slidably inserted into the corresponding coupling slot 20 inwardly from the peripheral edge 13 of the lens 10, the retention surface 311 IA of the retention inserter 31 IA is biased against the curved contacting surface 24 to securely retain the second connector 30A at the predetermined location of the respective lens 10.

Accordingly, the coupling shaft 312A is coupled with the retention inserter 31 IA. More specifically, the coupling shaft 312A is coupled with the retention inserter 31 IA to bias against the biasing surface 3112A thereof.

The clipping member 32 A is pivotally engaged with connecting member 3 IA, wherein the clipping member 32 A comprises a pressuring clipper 32 IA and a trigger 322A. The pressuring clipper 32 IA is pivotally coupled with the coupling shaft 312A of the connecting member 31 A while the trigger 322 A is extended from the pressuring clipper 32 IA. When the connecting member 31 A of the second connector 30A is slidably inserted into the coupling slot 20 at the peripheral edge 13 of the lens 10, the trigger 322A is actuated to pivotally move the pressuring clipper 321 A to bias against the biasing surface 3112A at the rear side 12 of the lens 10 such that temple units 2 and the bridge 3 can be quickly and firmly engaged with the lenses 10 by the clipping force.

As shown in Figs. 5 to 8, a second embodiment of the rimless spectacles illustrates an alternative mode of the first embodiment. As shown in Figs. 5 to 8, each of the second connectors 3OE comprises a connecting member 3 IE and a clipping member 32E, wherein the connecting members 3 IE are provided at the temple units 2 and the bridge 3 respectively. Each of the connecting members 31 A comprises a retention inserter 31 IE and a coupling shaft 312E, wherein the retention inserter 31 IE has a shape and size corresponding to the shape and size of the respective coupling slot 25. Each of the retention inserters 31 IE has a retention surface 31 HE and a biasing surface 31 12E, wherein the retention surface 31 HE is shaped and sized corresponding to the curved contacting surface 24. When the retention inserter 31 IE is slidably inserted into the corresponding coupling slot 20 inwardly from the peripheral edge 13 of the lens 10, the retention surface 31 1 IE of the retention inserter 3 HE is biased against the curved contacting surface 24 to securely retain the second connector 30E at the predetermined location of the respective lens 10.

Accordingly, the coupling shaft 312E is coupled with the retention inserter 31 IE. More specifically, the coupling shaft 312E is coupled with the retention inserter 31 IE to bias against the biasing surface 31 12E thereof.

The clipping member 32E is pivotally engaged with connecting member

3 IE, wherein the clipping member 32E comprises a pressuring clipper 32 IE and a trigger 322E. The pressuring clipper 32 IE is pivotally coupled with the coupling shaft 312E of the connecting member 3 IE while the trigger 322E is extended from the pressuring clipper 32 IE. When the connecting member 3 IE of the second connector 30E is slidably inserted into the coupling slot 20 at the peripheral edge 13 of the lens 10, the trigger 322E is actuated to pivotally move the pressuring clipper 32 IE to bias against the biasing surface 3112E at the rear side 12 of the lens 10 such that temple units 2 and the bridge 3 can be quickly and firmly engaged with the lenses 10 by the clipping force.

Accordingly, the only difference between the first and second embodiments is that the direction of the trigger 332A, 322E. Comparing Fig. 3 with Fig. 7, the trigger 322A of the second embodiment has a curved shape curving away from the optical lens 10. In other words, the tip of the trigger 322 A is pointing away from the optical lens 10. According to the sixth embodiment, the trigger 322E has a curved shape curving towards the optical lens 10 such that the tip of the trigger 322E is located adjacent to the peripheral edge 13 of the lens 10 as shown in Fig. 7.

Therefore, the four second connectors 3OE are aligned and located close to the peripheral edges 13 of the lenses 10 at the inner and outer sides thereof respectively so as to enhance the aesthetic appearance of the rimless spectacles and to enhance the actuating operation of each of the second connectors 30E.

As shown in Figs. 9 to 11, a third embodiment of the rimless spectacles illustrates an alternative mode of the first embodiment, wherein the spectacles is the rim-type spectacle incorporating with the connection mechanism. As shown in Fig. 9, the spectacles comprise two lenses 1OF. Each of the lenses 1OF has a front side 1 IF, a back side 12F, and a peripheral edge 13F located between the laterals of front and the rear sides HF, 12F.

The first connector comprises two lens rims 4F encirclingly holding around the peripheral edges 13F of the lenses 1OF respectively, wherein two temple units 2F are extended from two outer sides of the lens rims 4F respectively, and a bridge 3 F is extended between two inner sides of the lens rims 4F respectively.

As shown in Figs. 9 to 11, each of the lens rims 4F has a side opening 4 IF provided at the outer side to form a C-shaped structure and upper and lower engaging members 42F, 43F extended from two ends of the lens rim 4F at the side opening 4 IF, wherein when the upper and lower engaging members 42F, 43 F are biased against each other via a second connector 30F to close the side opening 4 IF, the respective lens 1OF is retained within the lens rim 4F. Preferably, each of the temple units 2F is extended from the respective lower engaging member 43F.

Each of the lens rims 4F further has a lens groove 44F indently provided at the inner surface of the lens rim 4F to engage with the peripheral edge 13F of the lens 1OF. Therefore, when the side opening 41F is closed, the respective lens 1OF is securely retained within the lens rim 4F.

Each of the second connectors 30F comprises a connecting member 31F and a clipping member 32F, wherein each of the connecting members 3 IF is coupled with the upper and lower engaging members 42F, 43F. The connecting member 3 IF has one end coupling with the lower engaging member 43F and an opposed end slidably extending through the upper engaging member 42F to pivotally couple with the clipping member 32F. Accordingly, the respective end of the connecting member 3 IF is a threaded end securely engaging with the lower engaging member 43F, wherein the coupling slot 25F is formed through the upper engaging member 42F for the connecting member 3 IF slidably passing through the coupling slot 25F.

The clipping member 32F is pivotally engaged with connecting member

3 IF, wherein the clipping member 32F comprises a pressuring clipper 32 IF and a trigger 322F. The pressuring clipper 32 IF is pivotally coupled with the corresponding end of the connecting member 3 IF while the trigger 322F is extended from the pressuring clipper 32 IF. When the trigger 322F is actuated to pivotally move the pressuring clipper 32 IF to bias against the upper engaging member 42F, the upper engaging member 42F is pressed to bias against the lower engaging member 43F so as to close the side opening 41F of the respective lens rim 4F. Therefore, the lens 1OF can be quickly and firmly retained within the respective lens rim 4F by the clipping force.

As shown in Figs. 12A to 12C, the clipping member 32F is pivotally moved among a releasing position, a locked position, and an anti-returning position. Accordingly, at the releasing position, the clipping member 32F is pivotally moved to enable the upper and lower engaging members 42F, 43F being separated apart to open up the side opening 4 IF, as shown in Fig. 12 A, such that the respective lens 1OF is freely removed from or placed within the lens rim 4F. At the locked position, the clipping member 32F is pivotally moved to close the side opening 41 F that the upper and lower engaging members 42F, 43 F are biased against each other so as to lock up the respective lens 1OF within the lens rim 4F, as shown in Fig. 12B. At the anti- returning position, the clipping member 32F is further pivotally moved to ensure the side opening 41 F being closed so as to securely retain the respective lens 1OF within the lens rim 4F and to prevent the clipping member 32F from being pivotally moved back to the releasing position, as shown in Fig. 12C. It is worth to mention that in order to pivotally move the clipping member 32F between the releasing position and the anti-returning position, the clipping member 32F must be pivotally moved at the locked position. In other words, once the clipping member 32F is pivotally moved at the anti-returning position, the clipping member 32F must be intentionally folded by an external force to the locked position before the clipping member 32F is moved to the releasing position. Preferably, the clipping member 32F is made of elastic material to enable the clipping member 32F being moved among the releasing position, the locked position, and the anti-returning position. Accordingly, the pressuring clipper 32 IF of the clipping member 32F has a sliding surface to slide at the upper engaging member 42F among the releasing position, the locked position, and the anti-returning position. The pressuring clipper 32 IF further defines a first surface point Pl when the pressuring clipper 32 IF is pivotally moved at the releasing position, a second surface point P2 when the pressuring clipper 32 IF is pivotally moved at the locked position, and a third surface point P3 when the pressuring clipper 32 IF is pivotally moved at the anti-returning position. As it is mentioned above, the pressuring clipper 32 IF is pivotally coupled with the connecting member 3 IF at the pivot point P thereof. A first distance between the pivot point P and the first surface point Pl is smaller than a second distance between the pivot point P and the second surface point P2 which is smaller than a third distance between the pivot point P and the third surface point P3.

The first distance is defined that the upper engaging member 42F is adapted to move apart from the lower engaging member 43F to open up the side opening 4 IF. The second distance is defined that the upper engaging member 42F is biased against the lower engaging member 43F to hold the lens 1OF within the lens rim 4F in position. The third distance is defined the upper engaging member 42F is biased against the lower engaging member 43 F to securely retain the lens 1OF within the lens rim 4F. Since the third distance is larger than the second distance, the clipping force at the anti-returning position is greater than the clipping force at the locked position.

In order to achieve the above mentioned feature, the pressuring clipper 32 IF of the clipping member 32F can be configured that the pivot point P is eccentric to a center of the pressuring clipper 32 IF.

Accordingly, the sliding surface of the pressuring clipper 32 IF of the clipping member 32F is slid among the releasing position, the locked position, and the anti-returning position. The sliding surface of the clipping member 32F has a curved surface portion to slide between the releasing position and the locked position. The sliding surface of the clipping member 32F further has a flat surface portion extended from the curved surface portion arranged when the pressuring clipper 32 IF is moved at the anti-returning position, the flat surface portion of the pressuring clipper 321F is biased against the upper engaging member 42F for further preventing the pressuring clipper 32 IF being slid back to the locked position.

It is worth to mention that the clipping member 32F of the second connectors 3OF, with the three different positions, can be used in the second connectors 3OE for the clipping member 32E coupling with the coupling slot 20 at the peripheral edge 13 of the lens 10. In other words, the clipping member 32E can be securely engaged with the rimless spectacle as well. Therefore, the clipping member 32E is pivotally coupled with the connecting member 3 IE to pivotally move among a releasing position, a locked position that the lens 10 is locked up with the frame, and an anti-returning position that the lens 10 is securely retained at the frame for preventing the clipping member 32E from being returned back to the releasing position. In addition, when the clipping member 32E is moved at the anti-returning position, the flat surface portion of the clipping member 32E is biased against the lens 10.

In addition, the second connector 3OF can further comprises a spring coaxially mounted at the connecting member 3 IF for applying an urging force against the clipping member 32F such that when the clipping member 32F is moved at the locked position, the spring will be stretched for applying a spring force against the clipping member 32F to push the upper engaging member 42F biasing against the lower engaging member 43F. When the clipping member 32F is moved at the anti- returning position, the spring will further be stretched for applying a greater spring force against the clipping member 32F to retain the upper engaging member 42F biasing against the lower engaging member 43 F. In other words, the spring will apply a greater spring force at the anti-releasing position than that at the locked position.

As shown in Fig. 13, a fourth embodiment of the rimless spectacles illustrates an alternative mode of the third embodiment, wherein the spectacles is a rim type spectacle. Accordingly, the first connector comprises two lens rims 4K encirclingly holding around the peripheral edges 13K of the lenses 1OK respectively, wherein two temple units 2K are extended from two outer sides of the lens rims 4K respectively, and a bridge 3K is extended between two inner sides of the lens rims 4K respectively.

Therefore, the lens frame 4OM can be quickly and firmly mounted behind the frame by the clipping force. Likewise, the clipping member 32F is pivotally moved among the releasing position, the locked position, and the anti- returning position.

As shown in Fig. 18, the spectacles of a seventh embodiment illustrates an alternative mode of the above embodiment, wherein the spectacles comprises a lens frame 40P coupling with the two lenses 1OP to retain the distance between the lenses 1OP. As it is mentioned above the frame comprises two lens rims 4P, a bridge 3 P extended between two inner sides of the lens rims 4P, and two temple units 2P extended from two outer sides of the lens rims 4P respectively. It is worth to mention that the shape of the lens frame 40P matches with the shape of the frame such that when the lens frame 4OP is mounted to the frame, the lenses 1OP will automatically aligned with the lens rims 4P respectively. The size of the lens frame 4OP is smaller than the size of the frame such that when the lens frame 4OP is mounted behind the frame, i.e. the rear side of the frame, the lens frame 40P is hidden behind the frame. The first connector 2OP comprises two lens connectors 22P sidewardly extended from two outer sides of the lens 1OP respectively.

The second connectors 3OP are provided at two outer sides of the lens rims 4P at the rear side thereof to detachably couple with the lens connectors 22P respectively so as to retain the lens frame 4OP behind the frame.

As shown in Fig. 19, each of the second connectors 30P comprises a connecting member 3 IP and a clipping member 32P, wherein each of the connecting members 3 IP is coupled with the respective lens rim 4P.

According to the preferred embodiment, the clipping member 32P is eccentrically coupled with the connecting member 3 IP to rotatably move between a releasing position and a locked position. At the releasing position, as shown in Fig. 2OA, the clipping member 32P is moved away from the respective lens connector 22P such that the lens frame 4OP is free to detach from the frame. At the locked position, as shown in Fig. 2OB, the clipping member 32P is moved to bias against the rear side of the lens connector 22P such that the lens frame 4OP is locked behind the frame.

The clipping member 32P is rotatably engaged with connecting member 3 IP, wherein the clipping member 32F comprises a pressuring clipper 32 IP and a trigger 322P. The pressuring clipper 32 IP, preferably having an oval shape, is rotatably coupled with the corresponding end of the connecting member 3 IP while the trigger 322P is extended from the pressuring clipper 32 IP. When the trigger 322P is actuated to rotatably move the pressuring clipper 32 IP to bias against the rear side of the lens connector 22P, the lens connector 22P is securely clipped between the clipping member 32P and the lens rim 4P. Therefore, the lens frame 4OP can be quickly and firmly mounted behind the frame.

5 IP integrally formed at the lens frame 4OP at a position between the two lenses 1OP, and comprises a bridge clip 52P provided at the bridge 3P of the frame to detachably engage with the engaging slot 5 IP to hold the lens frame 4OP behind the frame.

It is worth to mention that when the bridge clip 52P is detachably engaged with the engaging slot 5 IP to hold the lens frame 4OP in position, the user is able to rotatably move the clipping members 32P to bias the lens connectors 22P respectively. Likewise, when the clipping members 32P are moved away from the lens connectors 22P respectively, the lens frame 4OP is still held behind the frame. Therefore, the user is able to detach the bridge clip 52P from the engaging slot 5 IP to detach the lens frame 4OP from the frame.

As shown in Fig. 21, the spectacles of an eighth embodiment illustrates an alternative mode of the above embodiment, wherein the spectacles comprises a lens frame 4OP coupling with the two lenses 1OP to retain the distance between the lenses 1OP. As it is mentioned above the frame comprises two lens rims 4P, a bridge 3P extended between two inner sides of the lens rims 4P, and two temple units 2P extended from two outer sides of the lens rims 4P respectively. It is worth to mention that the shape of the lens frame 4OP matches with the shape of the frame such that when the lens frame 4OP is mounted to the frame, the lenses 1OP will automatically aligned with the lens rims 4P respectively. The size of the lens frame 4OP is smaller than the size of the frame such that when the lens frame 4OP is mounted behind the frame, i.e. the rear side of the frame, the lens frame 4OP is hidden behind the frame.

The first connector 2OR is formed as each of the two outer sides of the lenses 1OP respectively.

The second connectors 30P are provided at two outer sides of the lens rims 4P at the rear side thereof to detachably couple with t the two outer sides of the lenses 1OP respectively so as to retain the lens frame 4OP behind the frame.

As shown in Fig. 21, each of the second connectors 30P comprises a connecting member 3 IP and a clipping member 32P, wherein each of the connecting members 3 IP is coupled with the respective lens rim 4P. The connecting member 3 IP has one end coupling with the rear side of the respective lens rim 4P and an opposed end rearwardly extended that the clipping member 32P is rotatably coupling thereto. According to the preferred embodiment, the clipping member 32P is eccentrically coupled with the connecting member 3 IP to rotatably move between a releasing position and a locked position. At the releasing position, as shown in Fig. 22A, the clipping member 32P is moved away from the respective outer side of the lens 1 OP such that the lens frame 40P is free to detach from the frame. At the locked position, as shown in Fig. 22B, the clipping member 32P is moved to bias against the rear side of the outer side of the lens 1OP, i.e. the first connector 2OR, such that the lens frame 40P is locked behind the frame. It is worth mentioning that the clipping member 32P is directly biased against the outer side of the respective lens 1 OP at the peripheral edge thereof to lock the lens frame 4OP behind the frame. In other words, the two lens connectors 22P shown in the eleventh embodiment are the outer sides of the peripheral edges of the lenses 1OP respectively in this twelfth embodiment.

According to the above embodiments, the temple units 2 and the bridge 3 can be precisely and rapidly coupled with the lenses 10 via the above mentioned assembling structures. In addition, the lens 10 can be selectively cut in different styles according to the user's preference to incorporate with the temple units 2 and the bridge 3 via the above mentioned connection mechanisms. Therefore, there is no limitation of the lens, such as the shape, the size, or the thickness for incorporating with the connection mechanism.

Referring to Fig. 23 to Fig. 25 of the drawings, a rimless spectacles according to another preferred embodiment of the present invention is illustrated, wherein the rimless spectacles comprises two lenses AlO. Each of the lenses AlO has a front side Al l, a back side A12, and a peripheral edge A13 located between the laterals of front and the rear sides Al 1, Al 2. A plurality of first connectors A20 of the connection mechanism are spacedly provided at the peripheral edges Al 3 of the lenses AlO respectively at the inner and outer sides of each of the lenses AlO.

The rimless spectacles further comprise a frame which comprises two temple units A2 and a bridge A3. The temple units A2 are arranged to correspondingly couple with two outer sides of the lenses AlO respectively, and the bridge A3 is adapted to couple with two inner sides of the lenses AlO respectively.

The rimless spectacles further comprises a plurality of second connectors

A30 of the connection mechanism provided at the temple units A2 and the bridge A3 respectively, wherein the second connectors A30 are detachably engaged with the first connectors A20 at the lenses AlO to couple the temple units A2 and the bridge A3 with the lenses AlO to form the rimless spectacles without any tool.

As shown in Fig. 25, each of the first connectors A20 is a coupling slot A20 indently formed at the peripheral edge Al 3 of the respective lens AlO to define two spaced apart opening edges A21 at the peripheral edge Al 3 and an opening A211 between the opening edges A21.

More specifically, the coupling slot A20 has two side surfaces A22 and an enlarged arc surface A23 extending therefrom to form a coupling groove A25, wherein the two side surfaces A22 are facing toward each other and are inwardly extended from two opening edges A21 respectively. The distance between the two side surfaces A22 is larger than the distance between the two opening edges A21 such that the width of the opening A211 is smaller that the distance between the two side surfaces A22.

The arc surface A23, which is integrally extended from the two side surfaces

A22 respectively, defines a curved contacting surface A24, wherein the coupling groove A25, which is the coupling slot A20, is defined within the two side surfaces A22 and the curved contacting surface A24.

Referring to Fig. 24 and Fig. 26, each of the second connectors A30 comprises a retention element A31 and a fastening element A32, wherein the retention elements A31 are provided at the temple units A2 and the bridge A3 respectively. Each of the connecting elements A31 comprises a retention inserter

A311 and a coupling inserter A312 extended from the retention inserter A311. The shape of the retention inserter A311 is designed correspondingly to the shape coupling groove A25. The retention inserter A311 has a retention surface A3111 and a biasing surface A3112, wherein the retention surface A3111 is shaped and sized corresponding to the curved contacting surface A24. When the retention inserter

A311 is slidably engaged with the coupling slot A20, the retention surface A3111 of the retention inserter A311 is biased against the curved contacting surface A24 to securely retain the second connector A30 at the predetermined location of the respective lens 10.

Accordingly, the coupling inserter A312 is integrally extended from the retention inserter A311. More specifically, the coupling inserter A312 is integrally protruded from the retention inserter A311.

The fastening element A32, corresponding to the retention element A31, comprises a locking panel A321 and a locking unit A322. When the second connector A30 is placed at the coupling slot A20 of the lens AlO, the second connector A30 is fastened thereat via the locking panel A321 and the locking unit A322. In other words, after the retention inserter A311 is slidably inserted into the coupling groove A25 at the front side Al l of the respective lens AlO, the locking panel A321 is slidably biased against the biasing surface A3112 through the coupling inserter A312 at the rear side A12 of the lens AlO, such that the locking unit A322 is locked at the coupling inserter A312 to form a secured locking structure between the first and second connectors A20, A30. Therefore, the locking structures of the first and second connectors A20, A30 achieve the goal of fast and firmly connecting the temple units A2 and the bridge A3 with the lenses AlO to form the entire body rimless structure of the spectacles, as shown in Fig. 23.

Since the coupling slot A20 in the present invention is continuous channel defined by two opening edges A21 which are inwardly extended, such that it is unnecessary to drill any hole on the lenses AlO in the present invention. Technicians can easily cut at the peripheral edge Al 3 inwardly to form two side surfaces A22 and the arc surface A23 to form the coupling slot A20.

As shown in Figs. 27 to 29, the rimless spectacles of a tenth embodiment illustrate an alternative mode of the above embodiment of the present invention. The second connector A3 OB comprises a retention element A3 IB and a fastening element A32B, wherein the retention elements A3 IB are provided at the temple units A2 and the bridge A3 respectively. Each of the retention elements A3 IB comprises a retention inserter A3 HB and a coupling inserter A312B extended from the retention inserter A3 HB. The shape of the retention inserter A3 HB is designed correspondingly to the shape coupling groove A25. The retention inserter A31 IB has a retention surface A3111B and a biasing surface A3112B, wherein the retention surface A3111B is shaped and sized corresponding to the curved contacting surface A24. When the retention inserter A31 IB is slidably engaged with the coupling slot A20, the retention surface A3111B of the retention inserter A3 HB is biased against the curved contacting surface A24 to securely retain the second connector A3 OB at the predetermined location of the respective lens AlO. Accordingly, the thickness of the retention inserter A3 HB is smaller than a length of the coupling slot A20, such that when the retention inserter 31 IB is slidably inserted into the coupling slot A20 at the front side Al 1 of the lens AlO, the retention inserter A31 IB is disposed within the coupling slot A20. Since the distance between the opening edges A21 is smaller than that the distance between the side surfaces A22, the retention inserter A3 HB is securely retained within the coupling slot A20 so as to prevent the lateral movement of the retention inserter A31 IB. In other words, the temple units A2 and the bridge A3 can be fastened with the lenses AlO as long as the outward movement of the second connectors A3 OB is avoided.

Accordingly, the coupling inserter A312B is extended from the retention inserter A31 IB. More specifically, the coupling inserter A312B is protruded from the retention inserter A311 B, wherein the coupling inserter A312B is made of flexible material and is formed with an outer threaded circumferential surface A313B, such that the coupling inserter A312B is adapted to be selectively cut by a tool or other cutting equipment to reduce the length of the coupling inserter A312B.

The fastening element A32B, having a ring shape, is arranged to engage with the coupling inserter A312B. When the retention member A3 IB of the second connector A3 OB is inserted into the coupling slot A20 at the front side Al 1 of the lens

AlO, the fastening element A32B is rotatably engaged with the outer threaded circumferential surface A313B of the coupling inserter A312B at the rear side Al 2 of the lens AlO, so as to securely lock up the fastening element A32B at the rear side A12 of the lens AlO. In other words, the first and second connectors A20, A30B provide a fast and firm connection to couple the temple units A2 and the bridge A3 with the lenses AlO. Thereafter, a portion of the coupling inserter A312B rearwardly protruding out of the fastening element A32B can be cut to reduce the length of the coupling inserter A312B so as to allow the fastening element A32B tightly engaging with the coupling inserter A312B and avoid exposure of unused portion of the coupling inserter A312B, as shown in Fig. 29.

As shown in Figs. 30 to 31, the rimless spectacles of an eleventh embodiment illustrate an alternative mode of the first embodiment of the present invention. Each of the first connectors A20C is an engaging arm A20 integrally and outwardly protruded from the peripheral edge Al 3 of the respective lens AlO, wherein each of the engaging arms A20C has two engaging edges A21C formed at the peripheral edge A13 of the respective lens AlO. The engaging edges A21C are provided at the peripheral edge Al 3 with a predetermined separating distance A211C.

Each of the engaging arms A20C further has two engaging surfaces A22C and an arc surface A23C, wherein the two engaging surfaces A22C, which are the two lateral surfaces of the engaging arms A20C, are extended from the engaging edges

A21C respectively. The distance between the two engaging surfaces A22C is larger than the separating distance A221C between the two engaging edges A21C. The arc surface A23 is integrally extended between the two engaging surfaces A22C to form a curved contacting surface A24C from one of the engaging surfaces A22C to another engaging surface A22C through the arc surface A23. In addition, a protrusion connector A25C is formed by the encirclement of the curved contacting surface A24C.

As shown in Fig. 31, the second connectors A3 OC are provided at the temple units A2 and the bridge A3 respectively, wherein each of the second connectors A3 OC has a coupling groove A31C and a retention panel A32C. In other words, the coupling grooves A31C are indently formed at the predetermined locations of the temple units A2 and the bridge A3 respectively. Accordingly, each of the coupling grooves A31C has a bottom wall A311C and a peripheral wall A312C biasing against the curved contacting surface A24C, wherein a plurality of engaging teeth A3121C are formed at the peripheral wall A312C.

The retention panel A32C is shaped and sized corresponding to the coupling groove A31C such that the retention panel A32C can be fitted into the coupling groove A31C. In addition, a plurality of retention teeth A321C are formed at the retention panel A32C to engage with the engaging teeth A3121C when the retention panel A32C is engaged with the coupling groove A31C. Therefore, after the protrusion connector A25C of the engaging arm A20C is slidably engaged with the respective coupling groove A31C, the retention panel A32C is then engaged with the coupling groove A31C at the rear side Al 2 of the lens AlO to sandwich the engaging arm A20C between the bottom wall A3 HC of the coupling groove A31C and the retention panel A32C, so as to securely and rapidly couple the temple units A2 and the bridge A3 with the lenses AlO. It is worth to mention that an adhesive can be applied to the engaging arms 2OC to affix to the coupling grooves A31 C respectively to hold the engaging arms A20C in position.

As shown in Figs. 32 to 35, the rimless spectacles of a twelfth embodiment illustrate an alternative mode of the above embodiment of the present invention. The first connector A20D is a through engaging slot A20D provided at the predetermined location of the lens AlO. Each of the second connectors A30D comprises a connecting member A3 ID and a retention member A32D, wherein the connecting members A3 ID are provided at the predetermined locations of the temple units A2 and the bridge A3 respectively. Accordingly, each of the connecting members A3 ID is made of elastic material such as plastic. As shown in Fig. 36, each of the connecting members A3 ID comprises an elastic inserter A3 HD having a tubular structure, wherein each of the elastic inserter A31 ID has an elongated body A311 ID, an enlarged head A3112D extended from an end of the elongated body A311 ID, and an inner circumferential surface A3113D. In other words, the elongated body A311 ID and the enlarged head A3112D of each of the elastic inserter A31 ID form an inserting plug. In addition, an inserting cavity A33D is formed within the inner circumferential surface A3113D of each of the elastic inserter A3 HD. hi other words, when the elastic inserter A3 HD is slidably passed through the respective engaging slot A20D at the front side of the lens AlO, the enlarged head A3112D is located at the rear side of the lens AlO.

Each of the retention members A32D is slidably inserted into the inserting cavity A33D of the respective elastic inserter A3 HD. Accordingly, after the elastic inserter A3 HD is slidably inserted through the respective engaging slot A20D at the lens 10, the retention members A32D is then slidably inserted into the inserting cavity A33 D of the respective elastic inserter A31 ID at the rear side of the lens AlO so as to apply an outward pushing force against the elastic inserter A3 HD. Therefore, the- temple units A2 and the bridge A3 can be securely coupled with the lenses AlOD to form the rimless structure.

Figs. 37 and 38 illustrate an alternative mode of the rimless spectacles of the above embodiment, wherein the second connectors A3 OD is adapted to incorporate with the first connector A20 as shown in Fig. 25. As shown in Figs. 25, 37, and 38, each of the first connectors A20 is a coupling slot A20 indently formed at the peripheral edge Al 3 of the respective lens AlO to define the opening edges A21 and the coupling groove A25. As it is mentioned above, the distance between the two side surfaces A22 is larger than the distance between the two opening edges A21 such that the width of the opening A211 is smaller that the distance between the two side surfaces A22. Preferably the coupling groove A25 has a size slightly larger than the circumferential size of the elastic inserter A31 ID.

When the elastic inserter A3 HD is slidably passed through the respective coupling slot A20 at the front side of the lens AlO, the enlarged head A3112D is located at the rear side of the lens AlO. In particularly, the elongated body A311 ID of the elastic inserter A3 HD is biased against the side surfaces A22 of the coupling slot A20 when the retention member A32D is slidably inserted into the inserting cavity A33D of the respective elastic inserter A31 ID. It is worth to mention that the size of the elastic inserter A31 ID does not require to precisely match with the size of the coupling slot A20 in order to mount the elastic inserter A31 ID to the coupling slot A20. In other words, the size of the coupling slot A20 can be made not to precisely match with the elastic inserter A3 HD so as to reduce the manufacturing cost and defect of the optical lens AlO in responsive to the coupling slot A20.

According to the above embodiments, the temple units 2 and the bridge 3 can be precisely and rapidly coupled with the lenses 10 via the above mentioned assembling structures. In addition, the lens 10 can be selectively cut in different styles according to the user's preference to incorporate with the temple units 2 and the bridge 3 via the above mentioned connection mechanisms. Therefore, there is no limitation of the lens, such as the shape, the size, or the thickness for incorporating with the connection mechanism.
