DETAILED DESCRIPTION OF THE DRAWINGS
(22) The spectacle case according to the invention, as depicted horizontally in FIG. 1, is made of a material body 1, which may be a material of quite high stiffness but also elastic, returning to the initial shape (if bent) after bending. The material body 1 has a front side and rectangular rear side b, which may have rounded corners g, separated by a rectangular central surface c, sides a and b folding one along the other along the folding lines d and e. The rectangular central surface c must have a width sufficiently large for the glasses to enter the spectacle case properly. In the case of less rigid material, the folding lines d and e, as well as the edges of sides a and b, can be stiffened by hems and stitches. The central surface c is entirely elastic or only its lateral parts h are elastic. The rear side b is provided in the outer side with a notch f, curved towards the inside of the spectacle case. This notch f is intended to come in contact with the nose pads (pills) and thus fix the spectacle case on the glasses. In order to fit more than one type of spectacle size, the rear side b may have a slightly smaller surface than the anterior side of a, so that it can easily enter between the glasses' temples—FIG. 2.
(23) FIG. 3 shows, from the side, the spectacle case in the position of use and the manner in which the notch f is profiled. In order for the spectacle to easily return to its form of use and at the same time to stand firmly on the glasses, the central surface c is entirely made of an elastic material or only the sides h of the central surface c can be made of the spiral springs, or other elastic properties that return to their original shape after they are curved. The way of using the spectacle case is as follows: unwrap the spectacle case, place the glasses with the unfolded temples with the bridge to the rear side b—FIG. 4, then release the face so that the notch f comes in contact with the bottom of the nose pads, thus fixing the spectacle case on the glasses.
(24) FIG. 5 shows a spectacle case attached to the glasses.
(25) FIG. 6 shows a lateral view of the attached spectacle case in the final position, where the inner profile of the notch f is in contact with the nose pads of the bridge to fix the spectacle case on the glasses, the glasses being with the folded temples.
(26) FIG. 7 shows a narrower shape of the spectacle case, and the rear side b has a wavy surface, the outline of which contacts a longer length with the nose pads. For easier attachment of the spectacle case to the glasses, it can be provided with a central clasp 2—FIG. 8. The central clasp 2 consists of two sides, the anterior needle side and the rear side bc, which are integral with the sides a and b respectively, of the body 1. Side ac and bc are shown in FIGS. 10 and 19. The central clasp 2 is provided in its lateral parts which are at the surface of the body 1 with helical springs k or other similar resilient materials. The clasp 2 is disposed in the central region of the spectacle case, it is made of a rigid material, it has on the rear side bc the same notch f and has a width greater than the distance between the nose pads (pills) so that the bridge is contained inside the clasp and its nose pads come in contact with the notch f so that the clasp 2 and, implicitly, the spectacle case is attached to the glasses.
(27) The manner in which this constructive version of the spectacle case is attached is shown in FIG. 9. The clasp 2 may have various constructional shapes, and one of the most common forms of the clasp is the single helical spring m—FIG. 10 and FIG. 11. For the center clasp 2 may also have a constructional variant in which, instead of the notch f, the rear side of the clasp is provided with a profiled cavity 3 having a width greater than the usual distance between the nose pads, cavity shape 3 comprising entirely the nose pads of the bridge FIG. 12, thus fixing the spectacle case on the glasses.
(28) FIG. 13 is an overall view of this embodiment of the spectacle case with central clasp with profiled cavity 3. In order to better protect the lower portion of the glasses, the anterior side a and rear side b are provided with inwardly curved surfaces n, and these can even come in contact—FIG. 14.
(29) Another simple constructive version of the spectacle case is that in which the surface c is missing and the two sides a and b are respectively curved and the rear side b is curved so as to come into contact with the lower part of the nose pads of the bridge, thus fastening the spectacle case on the glasses. By prolonging the sides a and b so that they come in contact with one another, the constructive version of the spectacle case that fully protects the bottom of the glasses is obtained —FIG. 16
(30) It is possible to make a very simple version of the spectacle case, the sides a and b being flat and the inner part of the side b is provided with a horizontal pawl p for the nose pads of the bridge—FIG. 17 and FIG. 18.
(31) The same solution can be also applied to the clasp variant, in which case the ac and bc sides are flat and the bc side is provided internally with the pawl p, which has the function of fixing the nose pads—FIG. 19.
(32) For a better fixation of the nose pads, the inner face of the spectacle case or the bc side of the clasp can be additionally provided with two additional pawls q, which are in the form of rectangular surfaces disposed perpendicularly to the side b or the side bc, oriented vertically or obliquely with the pawl p, and the pawls q are intended not to let the nose pads move sideways. In order to achieve a firm attachment of the spectacle case, the inner sides a and b of the spectacle case or ac and bc of the clasp are provided in the central area with spacers r which are designed to form a space between them to accommodate several size types of bridges, but also to limit their movement inside the spectacle case—FIG. 20.
