DESCRIPTION:
BRIEF SUMMARY
The invention is concerned with a new constructive form of hinge for junction and opening of the arms on the front of glasses, and being the automatic closure of the arms, when the glasses aren't being worn. The innovative peculiarity of the invention is to provide the presence of an elastic means, operating on a pin of a mechanism, arranged in direct grip with a section of crown wheel, where it determines and regulates the movement of the gear, the gear itself being solid for the arm to open, whereas the section of crown wheel is fixed to the extremity of the hinge of front of glasses.
The hinge of the arms to the front of glasses has the evident aim to allow the opening and closing of the arms themselves, relative to the front, which supports them.
Countless constructive solutions of hinges for arms of glasses are well-known: from the most basic, consisting of simple eyelets, applied on the extremities of the joining parts and connected with a screw, acting as a pin, to the most complicated, which give assurance of a correct elasticity to the opened bars, so as to adapt themselves to the different anatomic conformations of those people, who wear the same type or model of glasses.
The use of one or other existent types of hinge already depends on the quality of the product, that one wants to obtain, on the pertinent prime costs, on the encumbrances of the hinges or other factors of constructive or commercial type.
But at the moment no type of hinge resolves the important and specific requirements of people, who wear glasses: that is the possibility of a mechanical and automatic closing of the arms on the front, when glasses aren't being worn. Junctions of arms on the front with a simple interposition of a helical--or another type of spring are well-known with a tendence to a continuous closure of the arms on the front: however the same elasticity makes the opening of the arms difficult, because these aren't hinged at the front, causing in this way the deformation of the whole glasses.
The problem underlying to this invention is to create a hinge, especially for the junction of the arm with the front of the spectacles, which consents a normal opening of the arms on the front, without deformation, being caused by a lack of thrust balance, for want of pins or centres of hinges, even securing the possibility of an automatic closure of the arms, when glasses aren't in use or when the opening action on the arms themselves has stopped.
Another problem underlying to the invention is to secure an opening and closing of the arms, which assures the symmetry and synchronisation especially during the automatic closing of the arms.
Another problem underlying to the invention is that of creating a hinge, which secures the correct pressure of the arms on the temples, as in the normal and well-known elastic hinges, though guaranteeing the automatic closure.
Hence the subject matter of the invention is a hinge for the automatic mechanical closure of spectacle-arms, determined to assure the automatic closure of the arms when the glasses are not being worn or they are not opened, charactarized by that arms are connected to the extremity of front, by means of a cover guided and contained in a box which box contains and fixes the extremity of an elastic means, working on the same cover with the interposition of gears or other mechanical regulators of the turning-friction, for regulating the reaction thrust of the elastic means, tending to the closure of arm on the extremity of front.
According to an advantageous embodiment of the invention the elastic means have an end connected to box, which is fixed on the extremity of front and presents an opposite end, applied to a stem of a crown wheel, which is directly attached to a toothed section of a disk, connected to box, while stem of crown wheel is attached to cover, which is connected to arm for transferring the crown wheel section having a width corresponding to the maximum width of the opening of arm.
According to another advantageous embodiment of the invention the transferen
