2. Description of Related Art
To achieve the objectives of offering great wearing comforts and facilitated portability of eyeglasses, most eyeglasses adapt the design of utilizing foldable temples for folding and storage purposes, in which the two temples are pivotally attached to the outer side of the two lenses. With such design, the two temples can be folded to the rear of the lenses for storage purposes by using the pivotally attached points as the center of rotations thereof and the effect of having a reduced storage space can be advantageously achieved.
However, despite the fact that the temples of the eyeglasses can be folded for storage, the pair of eyeglasses is still of a significant folded size with the two lenses aligned with each other in a row, which causes the reduced space of a pair of folded eyeglasses to be limited. Accordingly, there is a need for an improvement to effectively reduce the overall size of a pair of folded eyeglasses.
In view of the abovementioned drawbacks associated with the known arts, the inventor seeks to provide a solution for improvement after years of research and development, which is too an objective of the present invention.
An objective of the present invention is to provide a pair of eyeglasses with a foldable structure capable of using the foldable structure to fold the lenses of the pair of eyeglasses into a stack in order to effectively reduce the overall size of eyeglasses after folding such that the merits of being facilitated for storage with improved portability can be achieved.
To achieve the aforementioned objective, the present invention provides a foldable eyeglasses, comprising:
a first lens;
a second lens arranged correspondingly to the first lens; and
a foldable structure installed between the first lens and the second lens, the foldable structure comprising a first securement stand, a second securement stand, a swivel member and a universal joint; wherein the first securement stand is attached to the first lens; the second securement stand is attached to the second lens; the swivel member is pivotally attached to the first securement stand; the universal joint is constructed by a turning head portion extended from the swivel member and a receiving slot provided on the second securement; and wherein the turning head portion is pivotally attached to the receiving slot.
The present invention is also of the following technical effects:
First, by using the universal joint to allow the second lens to rotate vertically and relatively to the first lens, the first lens and the second lens are aligned with each other in a row and in a reverse direction. Further, the second lens is able to rotate horizontally with the swivel member such that it is folds toward the first lens in order to allow the second lens being stacked on top of the first lens. Finally, the temples of the eyeglasses can be further folded. As a result, the overall size of the pair of eyeglasses after folding can be minimized and such that the pair of eyeglasses of the present invention is of the merits of being advantageously facilitated for storage with improved portability.
Second, the first securement stand comprises two protrusions extended therefrom and spaced apart from each other in a top-down manner and a receiving slot formed between the two protrusions. The swivel member is pivotally attached to the two protrusions and received within the receiving slot in order to prevent the swivel member from being obviously exposed to the outer of the eyeglasses and to avoid any obstacles to the appearance of the eyeglasses; therefore, the swivel member is hidden inside the receiving slot such that the overall outer appearance of the eyeglasses can be improved.
