Embodiment Construction

[0065] figure 1 The embodiment is shown as a pair of spectacles 10, preferably reading glasses, in the state when a user puts them on his head. We call this state the open or unfolded state. The spectacles 10 include two side pieces (side piece 20a and side piece 20b ) and a front lens piece 30 . The side parts 20a and 20b are respectively connected to the ends of the front part 30 by hinges 25, preferably corner hinges.

[0066] Each of the two side parts 20 a and 20 b comprises a first part 21 adjacent to the front part 30 and a second part 22 remote from the front part 30 , the second part 22 extending from the first part 21 . Both the first part 21 and the second part 22 have a cross section, such as a C-shaped cross section, and the extension of the first part 21 is shorter than the extension of the second part 22 . Both the first part 21 and the second part 22 are made of a rigid or semi-rigid plastic material, a metal material such as aluminum, or a somewhat flexible...

Abstract

A pair of foldable spectacles has a two-lens front piece (30) to which two side pieces (20a, 20b) are pivotally connected by means of resilient corner hinges (25). The front piece (30) has a central hinge assembly (40) by means of which the front piece can be folded to a position where its lenses (31, 32) are held between and protected by the side pieces (20a, 20b). Each side piece (20a, 20b) has a first portion (21) which is connected to the front lens piece (30) by a resilient corner hinge (25), a second portion (22) which forms a free end portion of the side piece, and a resilient transition portion (23) between the first and second portions (21, 22). Thanks to the resilient corner hinges (25) and the resilient transition portion (23) of the two side pieces (20a, 20b), the spectacles (10) in use are held in place in a reliable manner since the side pieces (20a, 20b) are pressed against the side of the user's head.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of October 4, 2013, an application number of 201380050013.3, and a title of "foldable glasses". technical field [0002] The present invention relates to a pair of foldable eyewear, or eyeglasses, and more particularly to a foldable eyewear and a side piece of foldable eyewear. Background technique [0003] Foldable glasses, not only their side parts but also the hinge between the two lenses, have been around for a while. By folding the glasses differently, the size of the glasses will be reduced and the fragile lenses will be protected from external forces when the glasses are not in use. [0004] An example of such a spectacles is disclosed in the patent document WO2010 / 022900A1, which describes foldable spectacles with a folding device between two lenses that enables the lenses to be folded inwards so that the The foldable glasses have side pieces that protect the...
