Description

The present invention relates to the technical field of spectacles. The present invention is applicable to corrective glasses, sunglasses or any other types. More particularly, the present invention relates to an extension kit applicable to eyeglasses, and to eyeglasses to which the extensions are attached.

An already known goggles comprises a front and two attached to the front bracket, designed to run over the ears of a user and rest on it. The front includes two lenses or a single lens through which the user can look to improve his or her vision. The front further includes a nose bridge, designed to rest on the nose of the user.

The stirrups, together with the nose bridge, allow the spectacles to remain in place on the user's face when the user uses the spectacles and gazes through the lenses. In particular, each bracket has an end piece at the distal end relative to the front.

In some situations, it is necessary for the user to put on the glasses frequently and remove them from the eyes. This is especially true when using reading glasses when the user must alternately look at distant and near objects, and when using sunglasses when unforeseen light changes occur, such as when driving vehicles on tunnels.

For convenient use, it is desirable that the glasses, when the user does not look through the lenses, does not need to be stored, but that it can be easily worn by the user in a different position.

An already known solution is given by the use of a chain that connects the strap and that allows wearing the glasses over the neck. In particular, the strap of the glasses are used in designated eyelets of the chain.

However, the same chain may be too long or too short, depending on the physiognomy of the user. Too long chains around the user's neck can give rise to strong swirling of the glasses as they move, with the risk of the glasses bumping against external objects.

Further, eyeglass chains can easily catch and hold the glasses back, creating inconvenience around the user's neck.

The aim of the present invention is to solve the problems listed above, wherein the possibility of movement of the glasses and thus the risk of shocks is limited when the glasses are worn around the neck.

Another object of the invention is to allow the wearing of spectacles around the neck, bypassing the risk that the spectacles will get caught in external objects.

These and other objects are achieved with an eyeglass extension kit according to any of the claims set forth below.

Advantageously, in the use configuration, the second segments of each cap can rest behind the neck of the user and thus wear the glasses. Accordingly, the glasses do not hang down excessively from the neck, and their mobility is limited. Furthermore, the glasses can be worn through the neck, without there being any elements that can get caught.

Further features and advantages of the extension kit for spectacles according to the present invention will become apparent from the following description, illustrated by a preferred embodiment, which is given as an indication and without restriction, with reference to the accompanying figures, show the following:

With reference to the accompanying figures, a total of 1 is given an extension for spectacles. The extension 1, which is described in more detail below, is applicable to a pair of glasses 2.

The glasses 2 comprises a front side 3 and a pair of brackets 4. The front side 3 comprises at least one lens 31, as in the case of goggles, or a plurality of lenses 31, preferably two lenses. The front side may further include one or more frames 32 for holding the lenses 31 in position; a web 33 connecting the frames 32; and two tabs 34 adapted to rest on the nose of a user, and two nose portions 35 configured for connection to the straps 4. These features are already known to those skilled in the art and therefore not further described below.

The bracket 4 are mirror images of each other. Each bracket 4 is connected to the front 3, for example, at the level of one of the nose portions 35. Preferably, each bracket 4 is mounted by means of a hinge on the front side 3. Preferably, the brackets 4 are further interchangeable between a closed position in which the brackets 4 are placed on the front side 3, and an open position in which the brackets 4 are substantially parallel and spaced apart in a longitudinal direction X.

In the following description, the directions and distances, unless otherwise stated, relate to the glasses with the straps 4 in the open position.

In particular, each bracket 4 comprises a shaft 41 and an end piece 42. The shaft 41 is arranged between the front side 3 and the associated end piece 42. The end piece 42 is thus in a distal position relative to the front side 3. In the open position, the stirrups 4 and in particular the stems 41 define a plane of the stirrups 4.

The end piece 42 may have different shapes and dimensions. The end piece 42 is generally defined by an end portion of the bracket 4. When the shank 41 is made of metal, the end piece 42 may include a plastic coating (not shown) to improve contact with a user's head.

The end piece 42 may be inclined with respect to the shaft 41 of the associated bracket 4, and in the open position, the end piece 42 extends outside of the determined by the shanks 41 of the bracket 4 level. Preferably, each end piece 42 forms an obtuse angle with the shank 41 of the associated bracket 4 in order to conform to the ear of a user.

Each end piece 42 has an end portion 43. The end portion 43 or possibly the entire end piece 42 extend predominantly along a main running direction Y. It should be noted that the end pieces 42 of the stirrups 4 extend in two different associated main course directions Y.

According to the illustrated embodiment, the end piece 42 has a substantially flat end portion 43. In other words, the end portion 43 has a cross section defining a first cutting direction W and a second cutting direction Z which are perpendicular to each other and perpendicular to the main running direction Y. In particular, the cross section of the end portion 43 extends in the second cutting direction Z over a shorter length, i. H. a negligible distance, relative to a corresponding length in the

Patent office first cutting direction W. In general, the second cutting direction Z to the head of the user, so that the end portion 43 offers the user a smooth surface.

According to three different preferred standard typologies, the tails have

Cross-sectional dimensions, which correspond in particular in the first cutting direction W 3 mm, 5 mm and 13 mm.

According to one aspect of the invention, two extensions 1 are commonly applicable to a pair of glasses 2, as shown in Fig. 1. The two extensions 1 have the same characteristics and are mirror images of each other. In other words, the shape of any one of the extensions 1 is derivable from the shape of the other extension 1 via a symmetry with respect to a plane.

The two extensions 1 are mutually different and separate elements. The features given for a single extension 1 or for individual mirror-image parts of the glasses 2 are applicable as applicable to both extensions 1 or to both corresponding mirror-image parts of the glasses 2.

Each extension 1 has a body 5. According to one embodiment, the body 5 is made of elastomeric material. Even more preferably, the body 5 is made of silicone rubber, for example produced by injection molding from liquid silicone rubber (liquid silicone rubber molding). This material has several advantages including flexibility, resistance to low and high temperatures, UV radiation and aging. Advantageously, this material can have a tensile strength between 400% and 700%, a Shore A hardness between 30 and 70 and a breaking load between 5 N / mm ² and 12 N / mm ² , preferably between 9 N / mm ² and 11 N / mm ² .

The body 5 extends between a first end 51 and a second end 52. The body 5 has a first segment 53 and a second segment 54. In particular, the first end 51 is disposed on the first segment 53, and the second end 52 is disposed on the second segment 54.

Each extension 1 is adapted for attachment to an associated end piece 42 of the spectacles 2. In particular, the first segment 53 can be attached to the end piece 42.

In the following description applies, unless otherwise stated, for the mutual positions of the glasses 2 and the extensions 1 that the two extensions 1 are attached to the associated end pieces 42 (each with the brackets 4 in the open position). More specifically, the references to the main flow directions Y and the first cut direction W and the second cut direction Z relate to the position in which the two extensions 1 are attached to the associated end pieces 42.

The first segment 53 runs predominantly in the mentioned main direction Y. Preferably, the first segment 53 has a cavity 55 which is configured to receive the end piece 42 in a reversible manner. In particular, the cavity 55 receives the end piece 42 along the main direction.

The body 5 has at the first end 51 an opening 56 which can be traversed by the end piece 42 to allow the insertion of the end piece 42 into the cavity 55. The cavity 55 has a bottom 57 opposite the opening 56.

Preferably, the opening 56 has a substantially elliptical shape to hold the end piece 42 and in particular its end portion 43 and to prevent the rotation of the extension 1 relative to the end piece 42. More specifically, the opening 56 has larger dimensions in the first cutting direction W with respect to its dimensions in the second cutting direction Z, similar to the above description with respect to the end portion of the end piece 42.

When inserted through the opening 56 in the cavity 55 tail 42, the orientation of the extension 1 is fixed in an advantageous manner.

AT16 466U1 2019-10-15 Austrian

Patent Office Preferably, the opening 56 and / or cavity 55 are elastically deformable to permit insertion and retention of the end 42 in the cavity 55. Advantageously, the application of a force by the user is required to pull the tail 42 out of the cavity and the risk of accidental leakage during use is avoided.

According to the illustrated embodiment, the cavity 55 has a first portion 58. The opening 56 has smaller dimensions relative to the cross-sectional dimensions of the first section 58. In particular, the opening 56 has cross-sectional dimensions, measured in the first cutting direction W, corresponding to 3 mm. The first portion 58 of the cavity 55 has cross-sectional dimensions, in particular measured in the first cutting direction W, which correspond to 5 mm.

Advantageously, end pieces 42 having larger cross-sectional dimensions than the dimensions of the opening 56 may traverse the deformable opening 56 and be arranged in the first portion 58 of the cavity 56. In particular, end pieces 42 with cross-sectional dimensions of 5 mm can be positioned in the first section 58 without deforming the cavity 55. In contrast, as shown in Fig. 4 end pieces 42 with cross-sectional dimensions of 13 mm in the first section 58 with deformation of the cavity 55 can be positioned.

Preferably, the cavity 55 further comprises a second portion 59 which is disposed at the level of the bottom 57 of the cavity 55. In other words, the first portion 58 of the cavity 55 is disposed between the opening 56 and the second portion 59 of the cavity 55. The opening 56 has the same dimensions with respect to the cross-sectional dimensions of the second section 59.

As shown in Fig. 5, the end pieces 42 may be arranged with smaller or equal cross-sectional dimensions with respect to the opening dimensions 56, for example equal to 3 mm, advantageously in the second portion 59 of the cavity 55 to their free movement in the To prevent excavation 55.

Preferably, the extension 1 has a hole 11, which allows the escape of air from the cavity 55 during insertion of the end piece 42 into the cavity 55. Advantageously, the cavity 55 provides low mechanical resistance during insertion of the end piece 42.

The second portion 54 is inclined relative to the first portion 53. The second segment 54 extends along a main direction T. In particular, the second segments 54 extend along the associated, separate Hauptertralaufsrichtungen T. Specifically, the second segments 54 each have an extent between 2 cm and 8 cm, preferably equal to 3 cm ,

When the first segments 53 are each connected to the associated end piece 42, the second segments 54 project beyond the associated end pieces 42. Further, in this state, the main extending directions T of the second segments 54 are converged, as shown in Fig. 1, for example, so that the second segments 54 may rest on the neck of a user.

In particular, the distance between the end pieces 42 is greater than the distance between the second segments 54 of the corresponding extensions 1. These distances are measured in the longitudinal direction X and in particular on the level of the bracket 4, wherein the bracket 4 are in the open position and the end pieces 42 are connected to the first segments 53 of the associated extensions 1.

Again, in this configuration, each second segment 54 is inclined relative to the first segment 53 at an angle B ranging from 110 ° to 160 °, measured on the plane determined by the two stirrups 4, d. H. through the shafts 41 of the bracket. This angle B is given in particular by the projections of the first segments 53 and the associated part 4/12

AT16 466U1 2019-10-15 Austrian

Patent Office gene second segments 54 at this level. In other words, the angle B is determined by the projections at the level of the stirrups 4 in the main course directions T of the second segments 54 and in the main course directions Y of the associated end pieces 42.

While in the absence of the extensions 1 the neck of a user can easily pass the space between the end pieces 42 of the glasses 2, in the presence of extensions 1 there is advantageously no longer sufficient space for the passage of the neck between the extensions 1, and the glasses will not fall off your neck.

To the alignment of the second segments 54 described above relative to the end pieces 42, d. H. relative to the first segments 53, it can be seen that the main course direction T of each second segment 54 is in a substantially perpendicular plane to the first cutting direction W of the associated end piece 42, i. H. the corresponding first segment 53, lies.

According to the above description, the rotation of the extension 1 is prevented relative to the end piece 42 in an advantageous manner. Accordingly, the orientation of the second segment 54 is fixed. If the user wears the glasses around his neck, this orientation is particularly at least partially directed behind the neck of the user, although in embodiments of the invention not shown, the second segment 54 may also extend partially downwards, d. H. behind the user's shoulders.

The extension kit according to the invention can be used in conjunction with the glasses 2, wherein in particular each extension 1 is attached to the associated end piece 42. In particular, the attachment is accomplished by inserting the end portion 43 of the end piece 42 into the cavity 55 through the opening 56. At insertion, the extension 1 is due to the substantially flat shape of the end portion 43 of the end piece 42 and thanks to the elliptical shape of the opening 56 with respect to the end piece 42 aligned.

Then, a user wearing the glasses 2 with the extensions 1 in the face, with the end pieces 42 rest on the ears, or he can wear the glasses 2 around the neck, the second segments 54 of the extensions 1 rest behind the neck ,
