CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Taiwan Patent Application No. 100123790, filed on Jul. 5, 2011, in the Taiwan Intellectual Property Office, the disclosure of which is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to rotary glasses, more particularly to the rotary glasses with a sufficient support force so as to be set on a setting surface securely.
BACKGROUND OF THE INVENTION
A pair of glasses is a common vision correction tool. In general, lenses are embedded into a glasses frame of the glasses and provided for a wearer to wear in front of the wearer's eyes to improve vision, protect eyes, or serve as a decoration. The glasses frame generally includes a pair of glasses legs extended backwardly, such that when a wearer wants to wear the glasses, each glasses leg is set respectively on each ear on both sides of the wearer' cheek, so that the lenses are mounted in front of the wearer's eyes. If the user does not wear the glasses, the glasses legs on the wearer's ears are removed, and then each glasses leg is folded in order to store the glasses.
With reference to FIG. 1 for a schematic view of a pair of conventional framed glasses, the pair of conventional framed glasses comprises a frame 11 and two glasses legs 12, and the frame 11 includes two embedding holes 13 for embedding two corresponding lenses, and each glasses leg 12 is installed at upper edges on left and right sides of the frame 11 respectively. With reference to FIG. 2 for a schematic view of folding glasses legs of a pair of conventional framed glasses, if a user does not wear the glasses, each glasses leg 12 can be folded by a rotating method to the front of the glasses frame 11 in order to store the glasses, wherein the glasses leg 12 is turned in a rotating direction as indicated by the arrow A in the figure. With reference to FIG. 3 for a schematic view of folding a glasses leg of a pair of conventional frameless glasses, each glasses leg 14 of the frameless glasses is disposed on upper edges on left or right side of each lens 15 respectively. Similarly, the glasses leg 14 is folded in a rotating direction as indicated by the arrow B in the figure, so that each glasses leg 14 can be folded to the front of the lens 15 by the rotating method to facilitate the storage of the frameless glasses.
However, after the glasses leg disposed at upper edges on left or right sides of the frame or lens is folded forward, only the glasses frame or lens is provided for supporting the glasses on a disposing surface, so that the glasses may lose balance and topple over due to a slight external force such as a user touches the glasses frame or lens by accident. In other words, the supporting force of the glasses supporting force is insufficient and the glasses cannot be set on the disposing surface securely. When the glasses topple over, it may wear or damage the lens easily.
In addition, the conventional glasses are limited by the size of the wearer's head. For example, a user with a larger head requires a wider glasses frame, and a wearer with a small head requires a narrower glasses frame. Further, the conventional inwardly leg bent and folded glasses occupies a larger volume when it is stored, so that the disposing space cannot be saved when several glasses are stacked with one another. Obviously, the aforementioned conventional glasses require improvements.
SUMMARY OF THE INVENTION
In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a pair of novel rotary glasses to overcome the aforementioned drawbacks of the prior art.
It is a primary objective of the present invention to provide a pair of rotary glasses with a sufficient supporting force.
Another objective of the present invention is to provide a pair of rotary glasses that will not lose balance or topple over due to eternal factors.
A further objective of the present invention is to provide a pair of rotary glasses with a support portion of a glasses leg such that a user can longitudinally rotate the glasses leg by using a pivot element as an axis in a direction away from or towards an upper edge of a lens on demand.
To achieve the aforementioned objective, the present invention provides a pair of rotary glasses, comprising a lens, a glasses leg and a pivot element. A first pivotal transverse through hole formed on a non-upper edge of both left and right sides of each lens respectively. The glasses leg includes a support portion and a folding portion coupled with each other, and a second pivot portion disposed at an end of the support portion and corresponding to the first pivotal transverse through hole. The pivot element is optionally integrally formed with the glasses leg. If the pivot element is not integrally formed with the glasses leg, the pivot element is transversely passed through the first pivotal transverse through hole and the second pivot portion to pivotally couple the lens and the glasses leg with each other. If the pivot element is integrally formed with the glasses leg, the pivot element is transversely passed through the first pivotal transverse through hole to pivotally couple the glasses leg and the lens with each other.
