Foldable spectacles capable of unfolding automatically

Abstract

The invention relates to a pair of foldable spectacles capable of unfolding automatically. The spectacles comprise a first spectacle frame internally provided with a first lens, a second spectacle frame internally provided with a second lens, a first spectacle leg and a second spectacle leg, wherein the first spectacle frame and the first spectacle leg are connected by a first elastic member elastically; the second spectacle frame and the second spectacle leg are connected by a second elastic member elastically; the second spectacle frame and the second spectacle leg are connected by the second elastic member elastically; a middle beam mechanism is arranged between the first spectacle frame and the second spectacle frame; and a locking mechanism used for keeping the spectacles in a folding state when the spectacles are completely folded is arranged between the first spectacle leg and the second spectacle leg. The foldable spectacles have the advantages that the whole spectacles can naturally unfold and present a serviceable condition under the tension action of the elastic members only by pressing the locking mechanism by one hand of a wearer.

Description

technical field [0001] The invention relates to folding glasses, in particular to folding glasses that can be opened automatically with only one hand. Background technique [0002] Sometimes, such as driving or going to the bank or the airport, the wearer often only has one free hand. In this case, it is not very inconvenient to open the glasses. In order to solve this problem, the applicant of the present invention has previously proposed two Chinese patent applications, the application numbers are 200810217846.5 and 200910133429.7 respectively, and the title of the invention is "foldable glasses that can be opened automatically". The mirror frame, and the mirror frame and the mirror frame are used to realize the full opening of one hand of the folding glasses. However, in practical applications, this kind of glasses cannot completely bounce the two mirror frames of the glasses into a straight line, and most of them can only be flipped into An M shape, so there are still m...

[0002] Sometimes, such as driving or going to the bank or the airport, the wearer often only has one free hand. In this case, it is not very inconvenient to open the glasses

In order to solve this problem, the applicant of the present invention has previously proposed two Chinese patent applications, the application numbers are 200810217846.5 and 200910133429.7 respectively, and the title of the invention is "foldable glasses that can be opened automatically". The mirror frame, and the mirror frame and the mirror frame are used to realize the full opening of one hand of the folding glasses. However, in practical applications, this kind of glasses cannot completely bounce the two mirror frames of the glasses into a straight line, and most of them can only be flipped into An M-shaped, so there are many inconveniences to use

[0003] In order to solve this problem, the applicant proposes another solution, see Chinese Patent Document 101799591A, which discloses folding glasses that can be opened automatically. There are several types of structures. From the perspective of use effect, these types of center beam mechanisms can achieve good results. However, the fly in the ointment is that the structures of these types of center beam mechanisms are relatively complicated. On the one hand, it will increase the cost of the product. On the other hand, there is a risk of damage
