Abstract:
A case for glasses, consisting of a larger half-shell (1) and a smaller half-shell (2) made both of stiff material as metal or plastic and linked together by a hinge (3) in such a way as to allow the smaller half-shell (2) to progressively insert into the larger half-shell (1) when the case is in closed position, assuming a plurality of progressive deeper insertion positions, with snap-locking means provided at the front side of the case opposite to the hinge (3) and consisting of a plurality of equally spaced projections (10) or cavities (10â€²) which extend on the inner side of the front wall (101) of the larger half-shell (1) parallelly to the free edge of this wall and correspond to the progressive insertion positions, and of a cog means (9) which project outwardly on the free edge of the front wall (102) of the smaller half-shell (2) and co-operate with the projections (10) or cavities (10â€²) as to snap-locking the two half-shells (1, 2) together in each of the progressive insertion positions, characterised by the combination of the following features:a) the cog means of the smaller half-shell (2) comprise only one single cog (9), b) the single cog (9) and the projections (10) or cavities (10â€²) have a length shorter than the length of the corresponding front walls (101, 102) of the half-shells (1, 2) and are provided in coincident median strips of these walls, c) the cog-bearing front wall (102) of the smaller half-shell (2) has such an elastic deformability as to allow to be pushed inwardly for disengaging the cog (9) from the projections (10) or cavities (10â€²), d) in a substantially central position in the outer side of the bottom wall (5) of the smaller half-shell (2) a grasping recess (7) is provided which is dimensioned in such a way as to allow a finger of the hand to be at least partially housed therein, e) on the outer side of the front wall (102) of the smaller half-shell outside the larger half-shell (1) when the smaller half-shell (2) is in the completely inserted position, a grasping extension (11) is provided which projects beyond the front wall (101) of the larger half-shell (1) and allows to push inwardly the front wall (102) of the smaller half shell (2) also in its completely inserted position.
