Description

[0001] MAIN FRAME , SECONDARY FRAME AND RELATED MAIN FRAME¬

[0002] SECONDARY FRAME CLIP-ON ASSEMBLY

[0003] The present invention relates to a main frame , a secondary frame , and the related assembly main framesecondary frame with clip-on coupling .

[0004] The present invention is usefully employed in the field of eyewear .

[0005] Assemblies main frame-secondary frame with clip-on coupling are known, which provide a main frame to which a secondary frame can be coupled so that the lenses and the front of the secondary frame overlap the lenses and the front of the main frame .

[0006] In particular, it is known that the term clip-on refers to a typology of reversible coupling between a main frame and a secondary frame that allows to easily connect / disconnect them to / from each other as needed .

[0007] In known assemblies main frame-secondary frame with clip-on coupling, typically prescription lenses are mounted on the main frame , while sun lenses are mounted on the secondary frame . In this way, a person wearing prescription glasses can, i f necessary, also make the same prescription glasses he / she is already wearing sunglasses , or with a colour filter, without needing to wear a di f ferent pair of glasses and without needing special sunglasses with graduated lenses . Alternatively, the secondary frame can be a variant of the main frame for aesthetic purposes .

[0008] In another known embodiment , both the main frame and the secondary frame are for sunglasses or with colour filtering and / or an aesthetic variant .

[0009] In another known embodiment , less frequent , the main frame is for sunglasses or with colour filtering, and the secondary frame has prescription or ophthalmic lenses .

[0010] For example , clip-ons are known in which the coupling is of the mechanical type .

[0011] A first typology of clip-on with mechanical coupling provides attachments positioned on the lens contour of the secondary frame that allow the secondary frame to be interlocked onto the front of the main frame .

[0012] A second typology of clip-on with mechanical coupling provides a connecting element , positioned on the bridge of the secondary frame , which allows the secondary frame to be hinged to the bridge of the main frame . This typology of clip-on is particularly known as a flip-up clip-on since the secondary frame can remain connected to the main frame but the former can be li fted or lowered by rotating it with respect to the main frame .

[0013] Disadvantageously, in the case of mechanical coupling, the elements that allow the coupling are bulky and / or can interlock with other obj ects and be det ached / damaged .

[0014] The obj ect of the present invention is to overcome the above-mentioned drawbacks and in particular to ideate a main frame , a secondary frame , and a related assembly main frame-secondary frame with clip-on coupling, wherein the coupling between the secondary frame and the main frame is stable and wherein the components are durable over time .

[0015] The mentioned and other obj ects that will become more apparent below, are achieved by a main frame as recited in claim 1 , a secondary frame as recited in claim 7 , and a related assembly main frame-secondary frame with clip-on coupling as recited in claims 13 and 14 .

[0016] Further features of the main frame , the secondary frame , and the assembly are provided in the dependent claims .

[0017] The features and advantages will become more apparent from the description of preferred, but not exclusive , embodiments of a main frame , a secondary frame , and the related assembly main frame-secondary frame with clip-on coupling, illustrated by way of example and not limitation with the help of the attached drawings in which :

[0094] Preferably, the rear portion 214 ' of the side wal l 214 is configured in a complementary manner to the guide surface 124 . Advantageously, the guide surface 124 together with the one or more first magnets 130 and the one or more second magnets 220 promote the correct positioning of the secondary frame 200 on the main frame 100 during coupling .

[0095] Preferably, the guide surface 124 is transverse to the first and second coupling surfaces 127 , 215 . More preferably, the guide surface 124 is substantially vertical .

[0096] Still preferably, the guide surface 124 is recessed with respect to the housing portion 123 and with respect to the inner profile 128 of the first front 120 .
