Description

"Device for fastening the nose bridge and the temples to lenses of eyeglasses of the rimless type"
The present invention relates to a device for the fastening of the nose bridge and temples of eyeglasses of the rimless type. More particularly, the present invention relates to a fastening device for the bridge and the temples to lenses for eyeglasses of the rimless type, which consents to fasten at the desired angular positions the said temples and the bridge, so as to adapt the shape of the eyeglasses to the shape of the face of the wearer.
It is known that the temples and the nose bridge are fastened to the lenses of the eyeglasses of the so-called rimless type by means of pins or screws which are inserted into bores obtained on the said lenses; the screw together with its complementary nut locks the temple or the bridge in a fixed position onto the lens. Two or more bearing points of the bridge and of the temples are present in some models, at peripheral locations on the side of the lens, in order to avoid rotations of the bridge or of the temples around their fastening screw on the lens itself.
The suitable angular position to be imparted to the lens with respect to the nose bridge or to the temples is determined by the inclination of the bore and by the position of the mentioned bearing points on the lens into which there is inserted the mentioned fastening screw. By acting in such a manner, the angular position between the plane of the lens, in the zone where the bore is obtained and the bore itself is not orthogonal at all times.
The fastening of the temples and of the bridge onto the lens takes place by inserting the said screw into the bore and by locking the bolt with the complementary nut.
Said known fastening systems present relevant inconveniences.
In some cases, due to the non-orthogonality of the bore with the plane of the lens, a too much forced tightening of the nut may lead to damage the lens mtself. More generally, the use of the eyeglasses often involves torsions on the temples, which could act as a lever to generate veinings in the lenses, the whole being favoured by the cited absence of orthogonality between the lens and the bore.
Moreover, if the bearing points on the lens are not of the appropriate length, they can cause undesired movements of the bridge and of the temples along the edge itself of the lens. This may cause also the veining of the lens around the bore provided for the fastening of the screw.
Scope of the present invention is to obviate the mentioned inconveniences.
More particularly, the present invention relates to a fastening device for the nose bridge and temples to lenses of eyeglasses of the rimless type, which consents to fasten in an easy manner, at desired angular positions, the said temples and the nose bridge, in such a manner as to adapt the shape of the said eyeglasses to the shape of the face of the wearer.
A further scope of the present invention is to realize a fastening device for the nose bridge and the temples to eyeglasses of the rimless type having features of remarkable strength and reliability in the course of time, obtained in an easy and economical manner.
These and other purposes hereafter specified are obtained by the device for fastening the nose bridge and the temples to lenses of eyeglasses of the rimless type which is object of the present invention, comprising screws provided on the nose bridge at both extremities thereof and on the bent extremities of the temples, which are inserted in at least a corresponding bore obtained on the lenses, characterized by the fact that the extremities of the nose bridge and the bent estremities of the temples, where the said screw are provided, are shaped in such a manner as to be be inserted in perimetral slots or notches, obtained by a milling operation on one or both sides of the lenses, by perfectly matching the shape thereof.

The notches 19 are obtained on the lens 13 at a peripheral position, at opposed edges of same, with a side which opens on the said edges.
The bottom of the recessed portion or notch 19 is flat and perpendicular to the axis of bore 15 and determines the angular position between the lenses and the bridge. As previously mentioned, the shape of the notch 19 is complementary to the shape of both extremities 17 of the bridge 12 and to the shape of the bent extremity 18 of the temple 11, so as to consent the coupling between the said elements.
With reference to Figures 5, 6, 7 and 8 there is shown the fastening device according to a second embodiment for the fastening of a temple 21 and of a nose b idge 22 to a lens 23.
More particularly, the device comprises screws 24 provided on the nose bridge 22, at both extremities thereof, and at the bent extremity of the temple 21, which are inserted m corresponding bores 25 obtained on the lens; the screws 24 are tightened each on the opposed side of the lens 23 by a complementary nut 26 inserted into a seat 126 of equal dimensions provided in the rear side of the lens.
Both extremities 27 of the bridge 22 and and the bent extremity 28 of the temple 21, where the said screws 24 are present, are shaped in such a manner as to be inserted in perimetral slots or recessed portions 29, obtained by milling operation on the lens 23. At the center of the said slots there are arranged the said bores 25, for the fastening of the bridge 22 and of the temple 21 onto the lens 23. The slots or recessed portions 29 are obtained on the lens 23 in peripheral position, at the opposed edges of same .
The bottom of the recessed slot 29 is flat and perpendicular to the axis of the bore 25 and it determines the angular position between the lenses and the bridge. As previously mentioned the shape of the slot is complementary to the shape of both extremites 25 of the bridge and to the shape of the bent extremity of the temple 21, so as to consent the coupling between the said two parts.
The said bridge and temple extremities 27 and 28 comprise each a spacing disc 34 having shape and dimensions corresponding to the shape and dimensiones of the slot 29. Said spacing disc 34 presents a bore 134 aligned with the bore 25 of the lens 23 and two recessed portions or grooves 234 for accomodatmg partially the wires or tubular sections 32 which realize respectively the bridge 22 and the temple 21. The fastening device is completed by a locking element 30 carrying the screw and presenting two recessed portions or grooves 130 for accomodatmg at least partially and locking the wire or tubular sections 32 in cooperation with the spacing disc 34.
With reference to Figures 9, 10, 11 and 12 there is shown a fastening device according to a third embodiment for fastening a temple 41 and a nose bridge 42 to a lens 43.
More particularly, the device comprises on the bridge 42, at both extremities thereof, and at the bent extremity of the temple 41, screws 44 presenting a locking head 144. The screws 44 are inserted in corresponding bores 45 obtained on the lens 43. The screws 44 are tightened each on the opposed side of the lens 43 by a complementary nut 46 inserted in a seat of equal dimensions 146 in the rear portion of the lens.
According to a fundamental feature of the present invention both the extremities 51 of the bridge 42 and of the temple 41, are made of wire or tubular sections and loop- shaped in such a manner as to be inserted inside corresponding perimetral notches 49, obtained by milling operation on the lens 43. A the center of the said notches 49 there are obtained the said bores 45, for the fastening of the bridge 42 and of the temple 41 onto the lens 43. The notches 49 are obtained onto the lens 43 at a peripheral position, on opposed edges of same, with an open side on the said edge.
The bottom of the recessed notch 49 is flat and perpendicular to the axis of bore 45 and determines the angular position between the lenses and the bridge. As previously mentioned, the shape of the notch 49 is complementary to the shape of both extremities 51 of the bridge 42 and to the shape of the extremity 51 of the temple 41, so as to consent the coupling between the two parts.
Moreover, the screw 44 presents a substantially parallelepidal non-threaded portion 50 located beneath the locking head 144 of the screw, around which portion there come to be arranged for the locking inside the notches 49 the terminal annular or loop portions 51 of the bridge 42 and of the temples 41.
With reference to all of the above described embodiments, the bottom of the recessed slot 29, concerning the second described embodiment, or of the notch 19, 49, concerning the first and the third described embodiment, may even present the cited bore with angular positions which are different from the preferred perpendicular angular position. This is determined by the facial lineaments of the wearer which must wear the eyeglasses, which may require this type of solution for the angular position between the bottom of the milled recessed portion and the axis of the bore.
From the above structural description of the device object of the present invention, it appears evident the utilization of same.
According to all embodiments of the device, the fastening is naturally ensured by the coupling of the screw 14, 24, 44 and of the nut 16, 26, 46. The bottom of the milled notch 19 and 49 in the first and third embodiment and the bottom of the slot 29 in the second embodiment, determine the angular position by which the nose bridge 12, 22, 42 and the temples 11, 21, 41 will be secured to the lenses 13, 23, 43.
Therefore, after having established the complete conformation of the eyeglasses, calculated upon the facial lineaments of the wearer, it is possible to create the notches in the first case and the slots in the second case with the suitable angular position.
For the said operation a machine tool can be used, for example of the type disclosed in European patent Application EP-A-0 739 683.
From the above description of the structural and functional features of the device object of the present invention, the already mentioned advantages are even more evidenced. In fact, by having the possibility of orientating in a precise and easy manner the bridge and the temples, without the risk of damaging the lenses, there can be obtained eyeglasess which are very comfortable and arranged on the wearer's face in the exact position to consent the best sight.
The invention as above described and hereafter claimed has been illustrated by way of mere example, it being understood that same is subject to modifications and variations which however will fall within the limits of the same inventive concept.
For example, the extremities of the temples and of the nose bridge can be shaped with different shapes so as to avoid the rotation of same with resepct to the lens. As shown n Figure 13 the cited screw, moreover, can present its stem 514 which is eccentrical with respect to the head 515, so as to avoid the rotation of the temple or of the bridge locked by same onto the lens. The shape of the slots presents different configurations which are as well advantageous; for example, the bottom surface can be V-shaped or round as indicated respectively in Figures 14 and 15 by reference numerals 602 and 702. Therefore, the elements 601 and 701 which are inserted inside said slots or notches are shaped in a manner corresponding to the said bottom.
Finally, the sides of the milled portion can present different profiles and inclinations, having a shape any case corresponding to the side walls of the elements which are inserted inside the said milled portion.
Lastly, there are possible structural inversions or alternative positionings of the components which form as a complex the fastening device for the nose bridge and the temples to lenses of eyeglasses, object of the present invention.
