ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
An assembled eyeglasses disclosed in the invention among is formed by the assembling of a composite punch piece with the optical lens, and the punch piece can be bent into whatever mould in accord with the shape of the optical lens or to the liking of individual users.
(b) Description of the Prior Art
The eyes are the windows of one's soul. To protect the eyes or to rectify the eye-sight which are bias, both the people in China and the overseas countries contributed much time and energy in the research of the design and manufacturing of eye-glasses. However, their manufacturing method is generally confined to either injection molding or casting (as illustrated in FIGS.

&

). Due to the long time it would take in preparing the die for injection or casting and the necessity to have a set of die for making each and every style, it is really not economic to use when taking the time needed for development, the cost of the die and the casting.
What makes things worse is that, when a person who wears a pair of eyeglasses happened to fall on the ground, the broken pieces of the optical lens often unfortunately caused injury to the eyes of the user.
Therefore, if a design that can make a multiple changes of moulding with a framed piece in association with the optical lenses, it would reduce the cost of making the die, and also would meet the taste and preference of modem teenagers and youths in terms of buying. However, eye-glasses frame of such a design is not yet available in both domestic and overseas markets. In order to achieve this objective, this invention provides the manufacturing method of an eye-glasses frame, particularly denoting one shape of punched piece made of soft and hard composite materials capable of being bent to form different moulding and styles for the eye-glasses frame in association with various shapes of the optical lens, ultimately presenting an eye-glasses frame featured with creativity.
SUMMARY OF THE INVENTION
That is to say, the main objective of the present invention is to provide the manufacturing method of an eye-glasses frame made of composite soft and composite materials to cope with the different shapes of optical lens to hold the lens and form eye-glasses frames by means of bending.
Another objective of the present invention is to provide the manufacturing method of an eye-glasses frame without using any screw or glue.
A further objective of the present invention is to provide the manufacturing method of an eye-glasses frame, in which the elastic clamping and holding force of the edge of the frame itself is adopted in lieu of the traditional design of using two extension pieces with bending hooks hanging on the ears of the users to prevent the eye-glasses frames from falling off.
Another further objective of the present invention is to provide the manufacturing method of an eye-glasses frame, when the user is being violently bumped against and fall down onto the ground, and the bumping force the user received is beyond the holding and clamping force of the frame piece of the eyeglasses frame, the optical lens will fall off without causing any injury to the eyes of the user.
And yet another further objective of the present invention is to provide the manufacturing method of an eye-glasses frame, when the user is being bumped violently or falling down onto the ground, the part of the frame which is made of soft material will absorb the bumping force received by the part which is made of hard material to minimize the injury which might be caused to the face of the user.
A still further objective of the present invention is to provide the manufacturing method of an eye-glasses frame, of which the moulding can be designed and bent by individual users.
A final objective of the present invention is to provide the manufacturing method of an eye-glasses frame, in which it is so designed that various optical lenses can be changed by individual users.
