This invention relates to an eyeglasses assembling structure having an ancillary frame which comprises an adjustable ancillary frame disposed at an inner side of a main frame for adjusting an appropriate height, distance and angle of the ancillary frame on the main frame according to the needs of different wearers.
With the development of the social economy and the implementation of the two-day weekend, people began to pay attention to leisure activities. The outdoor leisure style that advocates nature is prevalent, and it also brings the craze for sightseeing and promotes people's willingness to travel or go out, e.g. surfing in the tropics, snorkeling, skiing in the cold regions, visiting interesting places and the like.
In general, users can only choose vision correction optical lenses, sunglasses, goggles or snow mirrors to wear. Although users wearing myopia glasses have clear vision, but they cannot wear sunglasses, wind goggles or snow goggles at the same time to avoid the damage by ultraviolet rays caused by excessive sunlight.
The conventional sunglasses, wind goggles, snow goggles and industrial goggles typically do not provide function of vision correction. Therefore, eyeglasses having a main frame and a secondary frame have been developed. Specifically, the main frame is equipped with vision correction optical lenses, and the secondary frame is provided with lenses for protection against ultraviolet rays, snow, dust or flying debris. Furthermore, the main frame and the secondary frame are combined with each other by magnets and the like. With this eyeglass design, users can save on the cost of making sunglasses, wind goggles, snow goggles or industrial goggles for vision correction and protection against ultraviolet rays, snow, sand or flying debris. However, the above eyeglasses is not cheap enough, and the main frame and the secondary frame are easily loose after a period of use. Additionally, the main frame and the secondary frame occupy a large space.
In order to shield light or isolate dust or flying debris from multiple angles and directions, wind goggles, snow goggles or industrial goggles are usually equipped with large glasses. Therefore, protective lenses can be adopted in the main frame, and optical lenses with vision correction function can be adopted in the secondary frame so as to completely cover the user's eyes and around the eyes and achieve a double effect. Although the above eyeglasses achieves the double effect, the main frame and the secondary frame cannot be adjusted according to the needs of different wearers. Therefore, when the different wearers actually wear the above structure, due to the difference in face shapes, nose heights and diopters, there is a discrepancy in viewing distance.
The present invention is aimed to provide an eyeglasses assembling structure having an ancillary frame which comprises an adjustable ancillary frame disposed at an inner side of a main frame for adjusting an appropriate height, distance and angle of the ancillary frame on the main frame according to the needs of different wearers.
The eyeglasses assembling structure having an ancillary frame of this invention is achieved by the following technical features. It comprises a main frame, an ancillary frame, a connecting part, an adjusting element and an engaging part. The connecting part is correspondingly engaged with the main frame at a lower end thereof and further provided with a plurality of engaging slots at an upper end thereof. The adjusting element is provided with a plurality of protrusions and an orientation part, and each of the plural protrusions engages with one of the plural engaging slots to adjust distance from the connecting part to the ancillary frame. The engaging part is disposed on the ancillary frame and correspondingly engaged with the adjusting element to adjust a rotation angle of the ancillary frame.
Accordingly, the ancillary frame can be correspondingly assembled in the main frame, and the height, the distance and the angle of the ancillary frame on the main frame can be adjusted according to the needs of different wearers so as to achieve effects of improving the clarity of viewing and the comfort of wearing.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments.

After the appropriate height and distance are adjusted, the orientation part (42) of the adjusting element (4) is embedded in and engaged with the receiving slot (51) of the engaging part (5) on the ancillary frame (2) so that the angles and positions of the ancillary frame (2) can be adjusted and positioned by the receiving slot (51). Specifically, the orientation part (42) is provided with a plurality of first positioning ribs (421), and the receiving slot (51) is provided with a plurality of second positioning ribs (511) for correspondingly engaging with the plurality of first positioning ribs (421) to rotate and position. Accordingly, the present invention achieves the effect of adjusting the viewing angle.
In addition to being assembled to each other by the structures of the plurality of first positioning ribs (421) and the plurality of positioning ribs (511), the orientation part (42) and the receiving slot (51) may also be assembled to each other by corresponding structures, e.g. a convex portion and a groove.
