## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a lens and nose-pad assembly with innovatory convenience and comfort features, and more particularly to a lens and nose-pad assembly that can be easily assembled and can be adjusted to proper positions to fit different sized noses of wearers and let them feel comfortable.
Description of the Related Art
A conventional lens and nose-pad assembly is known in the art of U. S. Pat. No. 6,386,705, to Chih-Lung Chen, the inventor of the present invention. The prior assembly, referring to FIG. 1, includes a nose-pad 1 and a lens 2.
The nose-pad 1 made of soft rubber is provided with a pair of inserting portions respectively on the left and right sides. Each inserting portion has a mounting rod 11 or 11′ on the front, a hollow 12 or 12′ in the center and a dented curve 13 or 13′ provided on the rear surface.
The lens 2 has a nose-pad cutout portion in the bottom edge. The cutout portion is provided with a lateral concave 21 or 21′ in the upper section of each side and a barb 23 or 23′ in the middle of each side. A protruding block 22 or 22′ is formed between each lateral concave 21 or 21′ and each barb 23 or 23′ on each side of the cutout portion.
While being assembled, referring to FIGS. 2 and 3, each protruding block 22 or 22′ is inserted into each hollow 12 or 12′ of the inserting portion so as for each mounting rod 11 or 11′ to be firmly secured to each side of the cutout portion with both ends of each mounting rod 11 or 11′ respectively inlaid in each lateral concave 21 or 21′ and barb 23 or 23′.
However, there are drawbacks in the above-mentioned conventional nose-pad assembly. After being used for a period of time, the nose-pads 1 made of soft rubber will be easily transformed by heat and lose elasticity, and the dented curves will be accumulated by dust. Besides, the conventional nose-pad assembly is designed for a wearer with a bigger nose, and it can not fit different sized noses of wearers.
SUMMARY OF THE INVENTION
Therefore, the present invention is to provide a position-adjustable lens and nose-pad assembly that substantially obviates the drawbacks of the conventional art.
An objective of the present invention is to provide a lens and nose-pad assembly which is easier to be assembled and saves cost.
Another objective of the present invention is to provide a lens and nose-pad assembly which can be adjusted to proper positions to fit different sized noses of wearers and let them feel comfortable.
Accordingly, a position-adjustable lens and nose-pad assembly in the present invention includes a nose-pad and a lens. The nose-pad is provided with an upper mounting rod and a lower mounting rod, and a hollow is formed between the upper mounting rod and the lower mounting rod. The lens is provided with an upper concave and a lower concave, the upper concave and the lower concave are respectively provided with successive through holes, and a flanged portion is formed between the upper concave and the lower concave.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 4, a position-adjustable lens and nose-pad assembly in the present invention includes a nose-pad 3 and a lens 4.
The nose-pad 3 is provided with an upper mounting rod 31 and a lower mounting rod 31′ , and a hollow 32 is formed between the upper mounting rod 31 and the lower mounting rod 31′. The lens 4 is provided with an upper concave 41 and a lower concave 41′, the upper concave 41 and the lower concave 41′ are respectively provided with successive first and second through holes 411, 412, 411′ and 412′, and a flanged portion 42 is formed between the upper concave 41 and the lower concave 41′.
While being assembled, referring to FIGS. 5 and 6, the hollow 32 of the nose-pad 3 is sleeved on the flanged portion 42 of the lens 4, and the upper mounting rod 31 and the lower mounting rod 31′ of the nose-pad 3 are respectively inserted in the upper concave 41 and the lower concave 41′ of the lens 4, so as for the nose-pad 3 to be firmly secured to the lens 4.
The position of the nose-pad 3 can be adjusted according to the size of a wearer's nose. If a wearer's nose is bigger, the upper mounting rod 31 of the nose-pad 3 may be inserted in the first through hole 411 or the second through hole 412 of the upper concave 41, and then the lower mounting rod 31′ is inserted in the second through hole 412′ of the lower concave 41′, as shown in FIG. 7.
On the contrary, If a wearer's nose is smaller, the upper mounting rod 31 of the nose-pad 3 may be inserted in the first through hole 411 of the upper concave 41, and then the lower mounting rod 31′ is inserted in the first through hole 411′ of the lower concave 41′, as shown in FIG. 8. If a wearer has a medium size of nose, the upper mounting rod 31 of the nose-pad 3 may be inserted in the second through hole 412 of the upper concave 41, and then the lower mounting rod 31′ is inserted in the first through hole 411′ of the lower concave 41′, as shown in FIG. 9.
Furthermore, in another embodiment of the position-adjustable lens and nose-pad assembly in the present invention, referring to FIGS. 10, 11 and 12, the upper concave 41 of the lens 4 may be provided with single through hole 411, and it can achieve the same effect as above-mentioned.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
