Description

glasses

The present invention relates to a pair of spectacles, and more particularly to a pair of spectacles without screw connection.

Referring to FIG. 1 , a conventional eyeglass leg bending device 1 includes a base plate 11 formed with two holes 110 spaced apart from each other, and a turning piece 12 connected to the front end of the eyeglass leg and extending from the eyeglass leg to pass through one of the holes 110, and then bending inwardly in an arc to pass through the other hole 110. Specifically, the turning piece 12 is in the form of an arc with opposite ends disposed in the holes 110, so that the turning piece 12 can be guided by the holes 110 to rotate along the circumference of the arc, thereby enabling the eyeglass leg to rotate between folding and unfolding.

However, in recent years, considering the comfort of wearing glasses, the design of glasses has gradually become lighter and thinner. When the structure of the turning piece 12 is a thin rod, it is very easy to deform under the conditions of wearing, long-term use, impact, etc. Once the turning piece 12 is deformed, it will not be able to maintain the preset arc shape, which will cause the temple of the glasses to not operate smoothly when bending.

Therefore, the object of the present invention is to provide a pair of glasses that adopts a screwless temple bending structure and can improve the operation stability and durability of the temple bending.

Therefore, the glasses of the present invention include a frame, two functional modules, and two legs respectively connected to opposite sides of the frame.

The lens frame includes two frame bodies which define two configuration spaces respectively suitable for arranging two lenses, and two extension pieces which extend outwards from opposite sides of the frame bodies and respectively define a structural cavity with an opening facing inwards.

The functional modules are respectively arranged in the structural cavities. Each functional module includes a substrate that seals the respective opening and has two holes that are spaced apart and penetrate each other, and a semicircular convex block that protrudes from between the holes of the substrate toward the respective structural cavity, and each convex block also has a guide groove formed on the periphery.

The mirror legs are respectively connected to the extension pieces of the mirror frame. Each of the mirror legs includes a rod body and an arc rod connected to the front end of the rod body and arranged in the guide groove and passing through the holes.

The effect of the present invention is that when the mirror legs are opened and closed, each arc rod is arranged in a respective guide groove and is closely attached to a respective round protrusion. Therefore, even when the mirror legs are used for a long time, frequently operated, or even accidentally subjected to external force, the arc rod of each mirror leg is still supported by the round protrusion, and thus always maintains a state of being able to rotate along the guide groove, so that the mirror legs can smoothly perform the rotation operation, thereby indeed improving the operational stability of the rotation of the mirror legs and the overall durability.

Referring to FIG. 2 and FIG. 3 , an embodiment of the eyeglasses of the present invention is shown, which comprises a frame 2, two functional modules 3 disposed on opposite sides of the frame 2, and two temples 4 respectively connected to opposite sides of the frame 2 in cooperation with the functional modules 3. The frame 2 comprises two frames 21 defining two configuration spaces 210 respectively suitable for arranging two lenses (not shown in the figure), two extensions 22 extending outward from opposite sides of the frames 21 and respectively defining a structural cavity 220 having an opening 221 facing inward, and two decorative panels 23 respectively disposed on the outer sides of the extensions 22 and used to exert a decorative effect. In this embodiment, it is considered that lenses are not necessarily required when worn, and the configuration of such lenses should also be common technology, so they are not shown in the drawings.

Referring to FIGS. 3 to 5 , the functional modules 3 are respectively disposed in the structural cavities 220 (FIG. 3 shows the functional module 3 on one side). Each functional module 3 includes a substrate 31 that closes the individual opening 221, a semicircular convex block 32 that protrudes toward the individual structural cavity 220, and a fixing screw 33. Each substrate 31 has two holes 311 that are spaced apart from each other and are through-holes, and a screw hole 312 for the fixing screw 33 to be screwed to fix the substrate 31 to the individual extension member 22. Each convex block 32 is protruded from between the holes 311 of the substrate 31 toward the individual structural cavity 220, and has a guide groove 321 formed on the periphery. Since each of the active modules 3 is sealed in the structural cavity 220 through the extension member 22 and the substrate 31, the structural cavity 220 can be protected from dust and water, and a blocking structure can be formed to prevent external impact.

The mirror legs 4 are connected to the extension pieces 22 of the mirror frame 2, respectively. Each of the mirror legs 4 includes a rod 41 and a curved rod 42 connected to the front end of the rod 41 and fitly disposed in the guide groove 321 and penetrated through the holes 311. Specifically, if the lightweight of the present embodiment is taken into consideration, each of the mirror legs 4 is preferably formed by bending a single metal rod. The curved rod 42 of each of the mirror legs 4 will generally continue to press against the individual round protrusions 32, and when the structural cavity 220 is not easily infiltrated by dust or water, it can also ensure that the curved rod 42 is stably fitted to the round protrusions 32.

Referring to FIG. 6 and FIG. 3 , when each of the temples 4 is opened or closed, the arc rod 42 is disposed in the guide groove 321 and is always closely attached to the round protrusion 32 , so that not only can the temples 4 be opened and closed stably, but also can be rotated more smoothly and without shaking due to the guiding effect of the round protrusion 32 . In addition, even if each of the temples 4 is operated multiple times for a long time or is subjected to external forces, the high-strength support of the individual round protrusions 32 can prevent the arc rod 42 from being deformed and affecting the operation, thereby maintaining the shape of each arc rod 42 and the close fit with the individual round protrusions 32, ensuring that the expansion and contraction operations of each temple 4 are normal and smooth.

In summary, in the embodiment of the eyeglasses of the present invention, when the temples 4 are opened and closed, each arc rod 42 is disposed in a respective guide groove 321 and located in a respective structural cavity 220, and is closely attached to a respective round protrusion 32, so that even when the eyeglasses are used for a long time, frequently operated, or even accidentally subjected to external force, the arc rod 42 is not deformed. When the mirror legs 4 are rotated, the arc rod 42 of each mirror leg 4 is still supported by the round protrusion 32, and because of the water-proof and dust-proof effect of the structural cavity 220, the arc rod 42 is always able to rotate along the guide groove 321, so that the mirror legs 4 can rotate smoothly, thereby improving the rotation stability and overall durability of the mirror legs 4. Therefore, the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
