Abstract:
Foldable spectacles capable of automatically springing open comprise a first spectacle frame (1) in which a first spectacle lens (2) is provided, a second spectacle frame (3) in which a second spectacle lens (4) is provided, a first spectacle leg (5) and a second spectacle leg (6). The first spectacle frame (1) is elastically connected with the first spectacle leg (5) by a first elastic component (7). The second spectacle frame (3) is elastically connected with the second spectacle leg (6) by a second elastic component (8). A middle beam mechanism (120) is arranged between the first spectacle frame (1) and the second spectacle frame (3), and a lock catch mechanism (10) is equipped between the spectacle legs (5, 6) for maintaining the spectacles in a folded state after completely closing the spectacles. The spectacles can be released into a useable state under the effect of the elastic components by pressing the lock catch mechanism (10) with a single hand by the wearer.
