Description

TITLE

Glasses with a frame elastically wearable on the top of the skull DESCRIPTION

Object of the present invention is a device made of two lenses or optical screens fixed to a frame to keep or wear in front of the eyes, to correct a visual deficit or to protect the eyes from external agents ( wind, powder, foreign bodies) or from the excess of brightness; the frame is basically made of an elastic clamp to be worn on the top of the head and whose back jaw presses in moderation on the nape, while the front jaw presses in moderation on the front head of the user.

Nowadays we know many frames for glasses, for instance: the ones with sidepieces, the clip-nose, the ones with the handle, with frame or visor. The usual frames have some problem. Some of them need three fulcrums and for this reason the optical axis of one lens or of the two lenses can be not in line with the one of the corresponding eye. Moreover, some frames need a string to avoid the falling of the glasses on the floor. It is annoying to wear this string and it can get caught in juts. Some others limit the internal or external visual field or the two of them together. Moreover, the usual frames do not permit the lifting of the mere lenses and they often require a technician to be fitted to the anatomy of the face of the user.

Sometimes with the usual frames, is impossible to use different lenses and, in case the user must change the lenses, the frame cannot be used Besides, the usual frames can be hit sideways and they must minimize the surfaces in front of the eyes, so that it is impossible to put logos, trademarks or personal identification elements on the frontal surface. Furthermore, these frames need long and big spectacle cases. The purpose of this invention is to avoid all the problems above-mentioned and to offer many advantages. In fact the frame, and also the glasses following the present invention, permit to low the production cost, makes the cost of maintenance null and also makes it a long-lasting frame. Moreover, the glasses of this invention have fulcrums chosen by the user following his need, very easily and nearly instinctively chosen, within a wide range, so that it is possible to reach the perfect alignment of the optical axis, for each eye, with its corresponding lens. Besides, the frame of this invention keeps the glasses well positioned and close-fitting on the head, making unnecessary any other binding. The present frame, as it is free of juts, has no possibility to get caught in some object. It permits also a complete visual field both in the inside and in the outside of the face. The frame of this invention permits the user to lift easily one or both the lenses and to keep them up, following his desire or necessity. Also, the frame of this invention is easily adjustable, so that every user can fit it by himself to his facial anatomy or to his need. The frame of this invention can be used with all types of lenses and can be used also afterwards, also after a long period, also by a common user without any technical knowledge. The frame of this invention has a smaller length of the normal frames and for this reason it is impossible to hit it laterally. The frame of this invention has a relatively wide surface near the front of the user and it is possible to reproduce some logo and/or some personal identification symbol on it. Besides, the frame of the present invention can be fold in smaller dimension of the regular glasses and consequently it needs a shorter and thinner spectacles case respect the other glasses. This and other benefits of the present invention will be pointed out in the following description, where, with the word glasses, frame we mean devices made by lenses or diaphragms fixed to a frame to correct a visual deficit or to protect the eye from external injuries (wind, powder, external bodies) or from the excess of brightness, and which will be, from now on, generically called glasses, lenses. Lenses can consequently be correction, tinted, coloured, unbreakable ones and can also be made of a metallic net. The inventor, with a stroke of intuition, decided to keep the lenses in front of the eyes with a thin elastic clamp which, fitting the superior centre of the skull, leans the posterior end to the nape and the anterior end to the front of the user.

To better explain the features of the present invention, we refer to the included designs which show a possible form of practical realisation in a schematic and only explicative way. Fig. 1 shows the frontal view of a woman head wearing a pair of glasses of this invention.

Fig. 2 shows in perspective the same pair of glasses illustrated in Fig. 1. Fig. 3 shows in perspective and completely the same glasses of Fig. 1 and 2, but here the lenses are designed in an intermediate lifting position, as when they are going to be totally folded and put in the spectacles case. Fig. 4 shows in perspective the same glasses of the previous figures, but here a posterior segment of the clamp, the one that presses in moderation on the nape of the user when the glasses are worn, is at an intermediate folding position, as when they are going to be totally folded and put in the spectacles case.

Fig. 5 shows in perspective the same glasses of the previous figures, but here both lenses and the posterior segment of the clamp are nearly totally folded to be put in a case which is not shown in the design. Fig. 6 shows, frontally, the jaw which must go against the front of the user and that represents the most important junction piece and that keeps the lenses hinged and together it keeps also the anterior end of the clamp. In this figure is indicated schematically the supporting arm of each lens in three different positions: in position of use, in an intermediate position and in a folded position as when you have to put it into a spectacles case. Fig. 7 shows a partial front view of the anterior jaw.

Fig. 8 shows a frontal view of the anterior jaw with the two pins where the two ends of the supporting arms carrying the lenses are hinged. Referring to the enclosed figures, we will describe more in details, one of the possible practical developments of the present invention given only for example.

Two lenses or optical screens or similar (1,2) that from now on we will say as lenses, are fixed to two arms (3,4) having their corresponding internal end hinged with special pins (5,6) on the body of a frontal jaw (7). The frontal jaw (7) is fixed to the back end of an elastic clamp (8,8') at whose posterior back is fixed the back jaw.(9). The elastic clamp (8,8') has a curved shape, so it can fit the dimension of the user's skull. Preferably the elastic clamp (8,8') is made of a haunch (8) and another haunch (8') linked by a hinge (10). Every haunch (8,8') is formed by two thin, long, narrow, identical, flexible plates, which are kept adherent and mated one another by two little bands, respectively 11-12 and 13-14. these bands, fromll to 14, are made in a particular material and dimension that makes a moderate and mutual friction between the two plates of the same couple that forms every haunch.

The inventor thought these devices to make the clamp universal, so that it can be suitable for all the heads of every shape and dimension. In fact, letting the plates and the bands (11,12-13,14) running opportunely, the haunches (8,8') became bigger or smaller following the dimension of the skull where the glasses have to be worn. Preferably, the jaws (7,9) have some little windows (15,16) as illustrated in fig.8, to let the sweat evaporate from the little area of the user's skin that is in contact with the jaw. For the same purpose, the surface in touch with the skin can be rough or knurled.

As the device has been described and represented only by way of example and it is not restrictive, it is possible to modify either the total invention or its details, and still not diverge from the basic principles which this invention is based on.
