ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a spectacle frame for detachably securing lens to the spectacle frame.
2. Description of the Prior Art
Typical spectacle frames comprise one or more frame members for retaining lenses therein. The frame members normally include a solid structure such that the lenses have to be forced into the frame members and such that the frame members may be damaged if the lenses are engaged into and disengaged from the frame members frequently.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional spectacle frames.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a spectacle frame including a structure or a device for easily and detachably securing the lenses to the spectacle frame without additional tools.
In accordance with one aspect of the invention, there is provided a spectacle frame comprising one or more frame members including a bridge portion and each including a space and a temple portion, and one or more lenses received in the spaces of the frame members. The frame member includes a pair of temple extensions extended rearwardly of each of the temple portions and/or extended inwardly of the bridge portion. One or more clamping devices are engaged onto the pair of temple extensions for forcing the pair of temple extensions toward each other to retain the lenses within the frame member such that the lenses may be easily and quickly engaged into or disengaged from the frame members when the clamping devices are disengaged from the temple extensions.
The temple portions of the frame members each includes a coupling portion provided therein, the spectacle frame further includes a pair of legs pivotally coupled to the coupling portions of the frame members at a pivot pin respectively.
One or two latches are pivotally secured to the respectively temple portions of the frame members and having the clamping devices provided thereon. Each of clamping devices includes a pair of spring blades engaged onto the pair of temple extensions to force the pair of temple extensions toward each other. Each of the spring blades includes a projection extended therefrom for engaging with the pair of temple extensions and each includes an outwardly inclined fin extended therefrom for facilitating engagement of the pair of temple extensions into the clamping device.
Each of the lenses includes a peripheral groove formed therein, the frame member is formed with a wire and is engaged in the peripheral groove of each of the lenses for securing each of the lenses in its respective frame member.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
