## Background
BACKGROUND
Field of Invention
The disclosure relates to an assembled structure of a spectacle frame and an assistant lens frame. More particularly, the disclosure relates to an assembled structure of easily and stably assembling an assistant lens frame onto a lens frame of a main spectacle frame.
Description of Related Art
In the present spectacle industry, spectacles are either clip-on type or magnetic type. The assistant lens frame with sunglasses of a clip-on spectacle is disposed in front of the main spectacle frame with optical lens, and a clip is disposed on the center of the assistant lens frame for fixing the assistant lens frame onto the main spectacle frame. Although the clip can fix the assistant lens frame onto the main spectacle frame, the assistant lens frame will be rocked when the user is dosing some activities. Therefore, the assistant lens frame cannot be stably fixed. For the magnetic spectacles, attracting magnetic parts are respectively disposed on the main spectacle frame and the assistant lens frame. However, the magnetic attracting force will be decreased as the using time of the magnetic parts is increased. Therefore, the assistant lens frame will drop when the user is doing some activities to cause the wearing and tearing problems of the lens of the assistant lens frame. Therefore, the existing clip-on or magnetic spectacles all are not capable of stably positioning the main spectacle frame and the assistant lens frame.
SUMMARY
This invention is related to an assembled structure of a main spectacle frame and an assistant lens frame. A main purpose of this invention is to provide a mutual positioning design of using positioning bumps on two sides of the assistant lens frame and fixing parts on two sides of the lens frame of the main spectacle frame to stably fix the assistant lens frame onto the lens frame of the main spectacle frame. Therefore, the assistant lens frame can be effectively prevented from being dropped from the main spectacle frame in activities.

DETAILED DESCRIPTION
First, please refer to FIG. 1. The assembled structure of an assistant lens frame of a spectacle comprises a main spectacle frame 1 and an assistant lens frame 2.
The main spectacle frame 1 has a lens frame 11. Two first lens assembling parts 12 disposed on the lens frame 11 for installing optical lens, such as near-sighted glasses, far-sighted glasses, or reading glasses. Two sliding slots 13 are respectively disposed on inner sides of the lens frame 11. Two through holes 14 are disposed on two front sides of the lens frame 11, and the through holes 14 are communicated with the sliding slots 13. The sliding slots 13 are extended to form connecting slots 15, and the connecting slots 15 are extended to the lateral sides of the lens frame 11. First locking holes 16 are penetratingly disposed on the two sides of the lens frame 11 from top to bottom, and the locking holes 16 penetrate the connecting slots 15. Fixing parts 17 are respectively disposed in the sliding slots 13 on two lateral sides of the lens frame 11. One end of the fixing parts 17 each has a tip rod 171 to be positioned to correspond to the position of the through holes 14. Serrated toggle parts 172 are respectively disposed on inner sides of the fixing parts 17, and the toggle parts 172 are slightly protruded from the sliding slots 13. A long slot hole 173 is disposed to vertically penetrate is the fixing part 17. An elastic part 174, such as a spring, is disposed in the long slot hole 173. The two sides of the lens frame 11 are respectively installed by a temple 18. Front terminals of the temples 18 are formed to be connecting sections 18 for connecting the connecting slots 15. Receiving parts 182 are disposed at the center of the connecting sections 181 of the temples 18 to correspond to the sliding slots 13 of the lens frame 11, and thus the fixing parts 17 can movably slide toward the receiving parts 182 of the temples 18. Second locking holed 183 vertically penetrate the connecting sections 181 of the temples 18 to correspond to the lock holes 16 of the lens frame 11. Two locking parts 19, such as bolts, are disposed to respectively penetrate the first locking holes 16 on two sides of the of the lens frame 11, the long slot holes 173 of the fixing parts 17, and the second locking holes 183 of the temples 18 to let the temples 18 and the lens frame 11 are pivotally connected. One ends of the elastic parts 174 in the long slot holes 173 of the fixing parts 17 are against the adjacent ends of the tip rods 171. The other ends of the elastic parts 174 are positioned to be against the locking parts 19 in the long slot holes 173 and penetrating the fixing parts 17.
The assistant lens frame 2 is disposed on a front side of the lens frame 11 of the main spectacle frame 1. The assistant lens frame 2 has two second lens assembling parts 21 for installing UV lens or other eye-protecting lens. The positions of the two second lens assembling parts 21 of the assistant lens frame 2 are corresponding to the positions of the two first lens assembling parts 12 of the lens frame 11 of the main spectacle frame 1. Positioning bumps 22 are disposed on two inner sides of the assistant lens frame 2 for penetrating the through holes 14 of the lens frame 11 of the main spectacle frame 1. Tip holes 221 are disposed on lateral sides of the positioning bumps 22 for being inserted by the tip rods 171 of the fixing parts 17.
Accordingly, a user can usually wear a main spectacle frame 1 with optical lens for correcting myopia, hyperopia, or presbyopia. When the user goes out for outdoor activities or for constructing works, the user will need to prevent UV or foreign matters from harming his/her eyes. Please refer to FIGS. 1 and 2 at the same time. Then, the user can take an assistant lens frame 2 with UV lens or eye-protecting lens to put on the front side of the lens frame 11. Please also refer to FIG. 3. Then, the positioning bumps 22 protrudingly disposed on two sides of the assistant lens frame 2 penetrate the through holes 14 on two sides of the lens frame 11 of the main spectacle frame 1. At this time, the user uses his/her hand to fiddle the serrated toggle part 172 to move the fixing part 17 toward the temples 18 and then slide to the receiving parts 182 of the connecting section 181 of the temples 18. At this time, the tip rods 171 of the fixing parts 17 escapes from the through holes 14 of the lens frame 11. The elastic parts 174 between the end of the long slot holes 173 of the fixing parts 17 and the locking parts 19 are compressed.
Please also refer to FIG. 4. After the positioning bumps 22 of the assistant lens frame 2 are placed in the through holes 14 of the lens frame 11 of the main spectacle frame 1, the user can release the fiddling of the fixing parts 17. At the same time, the compressed elastic parts 174 in the long slot holes 173 of the fixing parts 17 can restored to their original shape to return the positions of the fixing parts 17. The tip rods 171 of the fixing parts 17 also correspondingly insert into the tip holes 221 on lateral sides of the positioning bumps 22 of the assistant lens frame 2. Accordingly, the assistant lens frame 2 can use the positioning bumps 22 thereof to mutual position with the fixing parts 17 on two lateral sides of the lens frame 11 of the main spectacle frame 1. Then, the assistant lens frame 2 can be stably installed on the front side of the lens frame 11 of the main spectacle frame 1, as shown in FIG. 5.
Therefore, the eyesight of the user can go through the optical lens installed on the lens frame 11 of the main spectacle frame 1 for correcting his or her vision and then go through the UV lens or eye-protecting lens installed on the assistant lens frame 2 to observe the surrounding environment to prevent the damage from UV or splashing foreign matters. Furthermore, since the two sides of the assistant lens frame 2 are stably combined with the lens frame 11 of the main spectacle frame 1, the assistant lens frame 2 will not rock when the user are doing some activities. Moreover, the assembled structure above also won't have the problems of the magnetic type spectacles, i.e. the problem that the magnetic attracting force will be decreased as the using time of the magnetic parts is increased to cause that the assistant lens frame falls from the lens frame of the main spectacle frame to wear and tear the lens installed in the assistant lens frame.
The embodiments or figures above are not used to limit the implementation aspects. Please refer to FIGS. 6 and 7, which show an assembled structure of a main spectacle frame and an assistant lens frame according to another embodiment. In this embodiment, the assistant lens frame 3 has two separated frame bodies 31 respectively having a second lens assembling part 32. The positions of the second lens assembling parts 32 of the two frame bodies 31 are respectively corresponding to the positions of the two first lens assembling parts 12 of the lens frame 11 of the main spectacle frame 1 to be installed by UV lens or eye-protecting lens. The two sides of the front center of the lens frame 11 of the main spectacle frame 1 respectively have a pyramidal slot 10, and two sides of the two frame bodies 31 of the assistant lens frame 3 respectively have a latch 33 and a positioning bump 34. The pyramids formed by the latches 33 of the frame bodies 31 are respectively inserted into the pyramidal slots 10 located on two sides of the center of the lens frame 11 of the main spectacle frame 1. The positioning bumps 34 of the frame bodies 31 respectively penetrate the through holes 14 on two sides of the lens frame 11 of the main spectacle frame 1. Tip holes 341 disposed on lateral sides of the positioning bumps 34 are used to be correspondingly inserted by the tip rods 171 of the fixing parts 17 on two sides of the lens frame 11 of the main spectacle 1, as shown in FIG. 8. Therefore, the stable positioning effect of the two frame bodies 31 of the assistant lens frame 3 is obtained by using the latches 33 and the positioning bumps 34 on two sides thereof as well as the lens frame 11 of the main spectacle frame 1. Some proper modifications and variations done by persons having ordinary skills in the art can be viewed as without departure from the scope of the assembled structure of an assistant lens frame of this invention.
