Abstract

The present invention is an elastic miniaturized hinge for flex temples with an articulation trolley provided at least with a seat for the housing of the spring. A box is placed along the temple of the glasses. A housing along the box contains an articulation trolley. The articulation trolley includes at least one spring and is contained inside of the box, while the portion that includes the articulation exits from the front end of the box. The tie-rod body of the articulation is provided with a base, being provided with at least one seat that houses the rear end of the corresponding spring. Peripherally with respect to the opening of the housing, at least one guiding zone is obtained. Furthermore, the protrusion is provided with a guiding seat with an opening along the front profile and longitudinally projected with respect to the sliding longitudinal axis of the articulation trolley.

Claims

1. An elastic miniaturized hinge for use with a temple of eyeglasses, the hinge comprising:

a box suitable for affixing to the temple or a lug of the eyeglasses;

a housing extending along an interior of said box;

a trolley contained within said housing, said trolley having an articulation at one end thereof;

at least one spring contained in said box, the spring bearing against said trolley and against said interior of said box, said box having an open end, said articulation extending outwardly of said open end of said box, said trolley having a tie-rod body with a base projecting orthogonally therefrom at an end thereof interior of said housing, said base having at least one seat formed in a surface thereof, the seat housing an end of said at least one spring; and

a guiding zone formed at said opening of said housing, said guiding zone having a first protrusion and a second protrusion in generally spaced parallel relationship to each other and extending longitudinally outwardly therefrom, said first protrusion having a cheek facing a cheek of said second protrusion, said articulation having a first lateral face and a second lateral face on opposite sides thereof, said first lateral face being adjacent to and in sliding relation with said cheek of said first protrusion, said second lateral face being adjacent to and in said sliding relation with said cheek of said second protrusion, each said first and second protrusions having a guiding seat formed therein.

2. The hinge of claim 1, said seat of said base being a circular seat.

3. The hinge of claim 1, said box and said end of tie-rod body having a T-shape, said base having a first surface on one side of said tie-rod body and a second surface on an opposite side of said tie-rod body, said housing having an internal wall, said at least one spring comprising:

a first compression spring bearing against said first surface of said base and against said internal wall of said housing; and

a second compression spring bearing against said second surface of said base and against said internal wall of said housing.
