Nowadays, sunglasses are considered as one of fashion accessories for people, wherein people have high demand for styling of sunglasses. For example, these sunglasses have curvy shape that to match with the curvature of the head of the user such that the sunglasses fit to be worn by the user. These types of sunglasses are already hard to make because of the curving shape of the lenses. In addition, these types of sunglasses are difficult and expensive to manufacture especially the sunglasses lens having the optical effect for people who needs vision correction. One option for these people is to wear a “clip on” style detachable sunglasses frame which is mounted in front of the optical lenses for providing a sunlight blocking function. Another option is to wear sun-sensor glasses that the optical lenses are automatically changed its tint to become darkest in bright sunlight and to become clear in normal light condition. The problems with the above mentioned glasses are that the sun blocking utilization quality is poor and the lens styles are very limited due to the restriction of the shape of the optical lens.
Aside from sun blocking utility like regular sunglass, there are may other applications for spectacle frame. For example, ski or snowboard users often wear anti-reflective lens, laboratory users often wear protective lenses for providing protection against various chemical materials or even explosion. A common problem for these users is that the reflective or protective lenses do not provide the optical aid for the users who needs vision correction.
The main object of the present invention is to provide a multi-purpose spectacle frame set, wherein a user can use the same pair of optical lenses to incorporate with a regular spectacle frame or a utility spectacle frame.
Another object of the present invention is to provide a multi-purpose spectacle frame, wherein the user can conveniently interchange the optical lenses between the regular spectacle frame and the utility spectacle frame.
Another object of the present invention is to provide a multi-purpose spectacle frame, which does not involve complicated mechanical structure and can simplify the manufacturing process and maintenance cost.
Accordingly, in order to achieve the above objects, the present invention comprises a detachable spectacle frame having a plurality of hangers and a lens supporter supporting a plurality of optical lenses in front of eyes of a user, a frame adapter which is adapted to combine a utility spectacle frame with the optical lenses such that the user can conveniently uses the optical lenses for different kinds of utility spectacle frame.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
The present invention provides a multi-purpose spectacle frame set 10 which comprises a detachable spectacle frame 11 comprising a plurality of hangers 20 and a lens supporter 30. The multi-purpose spectacle frame set 10 further comprises a plurality of optical lenses 40 and a frame adapter 50. When a user wants to switch to sunglasses, the user can detach the hangers 20 and lens supporter 30 from the optical lenses 40. The optical lenses 40 can then be attached onto the frame adapter 50 which couples with a utility frame 70, such as a pair of sunglasses. Thus, the user can conveniently use the same set of optical lenses 40 for both regular optical glasses and sunglasses purposes.
According to the preferred embodiment of the present invention, the detachable spectacle frame 11 is an optical spectacle frame. The optical lenses 40 can be detached from the optical spectacle frame 11 and then detachably coupled with the utility spectacle frame 70. The utility spectacle frame 70 can be a sunglasses or a protective spectacle. In other words, the optical lenses 40 can be detachably mounted to the sunglasses or the protective spectacle such that the user does not require purchasing the sunglasses or the protective spectacle with vision correction ability.
According to the preferred embodiment, the two hangers 20 are embodied as two temple arms detachably coupling with two outer sides of the optical lenses 40 respectively. The lens supporter 30 is embodied as a bridge having two ends detachably coupling with two inner sides of the optical lenses 40 respectively.
According to
The hangers 20 and lens supporter 30 of the detachable spectacles frame 11 further comprise a plurality of connectors 21, 31 at an end thereof corresponding to the plurality of slots 41 of the optical lenses 40. Accordingly, two first connectors 21 are provided at the front ends of the hangers 20 respectively to detachably engage with the slots 41 at the outer sides of the optical lenses 40 respectively. Two second connectors 31 are provided at the ends of the lens supporter 30 respectively to detachably engage with the slots 41 at the inner sides of the optical lenses 40 respectively.
Each of the first and second connectors 21, 31 of the hangers 20 and lens supporter 30 is slightly larger in size comparing to the slots 41 of the optical lenses 40. As shown in
Accordingly, the first connectors 21 as the same as the second connectors 31 in which the first connectors 21 are located at different locations of the optical glasses frame to detachably couple at different locations of the optical lenses 40. Each of the first connectors 21 comprises a pressing head 211 and a resilient unit 212 provided at the front end of the respective hanger 20 and the pressing head 211 for applying a clipping force against the pressing head 211 to engage the respective optical lens 40 between the pressing head 211 and the front end of the respective hanger 20, as shown in
The resilient unit 212 comprises a housing 2121 rearwardly extended from front end of the respective hanger 20, a sliding shaft 2122 slidably extended from the housing 2121 to pivotally couple with the pressing head 211, and a resilient element 2123 disposed in the housing 2121 to apply the clipping force against the pressing head 211 through the sliding shaft 2122.
The pressing head 211 has a flat pressing surface 2111 for pressing on an inner surface of the respective optical lens 40 and a curved corner 2112 which is extended from the flat pressing surface 2111 and arranged when the pressing head 211 is pivotally turned at the curved corner 2112, the pressing head 211 is moved away from the inner surface of the respective optical lens 40 to detach the optical lens 40 from the respective connector 21.
The pressing head 211 further has an actuation tip 2113 extended from the flat pressing surface 2111 at a position opposite to the curved corner 2112, wherein the actuation tip 2113 is actuated by the user to pivotally move the flat pressing surface 2111 of the pressing head 211.
