The present invention relates to a glasses frame structure and, more particularly, to a glasses frame structure that can be fitted with side lenses more easily and firmly.
Generally, glasses can be classified into two categories: medical corrective glasses and eye protection glasses, according to their functions. Eye protection glasses can be used for protecting human eyes from ultraviolet or intense light due to snow, foreign matter due to chemical sputtering, lathe cutting, milling or drilling, glare of computer display, X-ray, laser, intense light due to welding, dust, or pollen. Also, eye protection glasses can be used for the military use or town violence. With the improvement of quality of life, the increase in outdoor sports, and the popularization of eye medical and protection knowledge, there are various glasses products coming in the market, such as military glasses, sport safety glasses, working protective glasses, chemical protective mask, and motorcycle goggles. People increasingly demand the quality of the glasses products.
In conventional safety glasses, for protecting the eyes of engineering staff, athletes or workers, the glass frames are provided with side structures or shields. The protection level of the safety glasses, which can be determined by using an air gun to strike the lenses of the safety glasses at a specified velocity and a specified pressure several times, is generally divided into low standard (such as the standard required in Japan, wherein the lens to be tested should not fall from the associated frame by a gun fired at a velocity between 90 and 110 miles per hour), intermediate standard (such as the standard required in European countries, wherein the lens to be tested should not fall from the associated frame by a gun fired at a velocity of 120 miles per hour), and high standard (such as the standard required in US, wherein the lens to be tested should not fall from the associated frame by a gun fired at a velocity between 160 and 165 miles per hour). In conventional safety glasses, for increasing the capability of a glasses frame resisting an impact and increasing the safety level of the glasses frame, the side structures or shields thereof are required to be widen and thickened. In one example of conventional safety glasses, as disclosed in Publication Number 255500 and 255733 of Taiwan Patent, the chassis is curved backwardly to provide lateral protection for eyes. In another example of conventional safety glasses, as disclosed in Publication Number 385014 of Taiwan Patent, the chassis defines a V-shaped groove for holding the lenses, wherein the groove is unequal in its two sides, and one side of the groove is provided with one stop edge to increase the safety level of the glasses frame. A further example of the conventional safety glasses, as disclosed in Publication Number D127510 of Taiwan Patent, shows that the chassis defines side rims that can be fitted with side lenses. The conventional safety glasses hold the side lenses only via the side rims. There is still room for improving the conventional safety glasses. A further example of the conventional safety glasses, as disclosed in D138775, shows that the chassis defines slots for mounting the associated lenses.
The applicant has engaged in the processing and manufacturing of glasses for many years. After years of effort and repeated tests to overcome the shortcomings of conventional glasses frames, an enhanced glasses frame is thus invented and disclosed herein.
One object of the present invention is to provide an enhanced safety glasses frame, wherein the chassis thereof has a pair of side rims to each receive a first side lens, and each of the temples thereof has a rimmed portion to receive a second side lens. One advantage of the present invention is that the glasses frame can be made in a variety of styles while the side lenses can be made in a standard size to facilitate installation of the side lenses. With the present invention, the side lenses can be fixed more easily and firmly, the safety level of the glasses frame can be increased, and the cost of the glasses frame can be reduced.
Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The following paragraphs will illustrate one embodiment of the present invention in detail to allow the technical contents, features and advantages of the present invention to be understood more easily.
