    专利说明:

    [0001] The present invention develops in the technical field of eyeglasses. The present invention is applicable to eyeglasses, sunglasses or any other type. In particular, the present invention relates to a kit of extensions applicable to glasses and a pair of glasses to which the extensions are applied.
    [0002] A known eyeglass comprises a front and two rods, constrained to the front, and configured to pass over the ears of a user and rest on them. The front includes two lenses, or a single lens, through which the user can look to improve his vision. The front also includes a nose piece configured to rest on the user's nose.
    [0003] The temples, together with the nose piece, allow the glasses to remain in position on the user's face when the user uses the glasses while looking through the lenses. In particular, each rod has a terminal at the distal end with respect to the front.
    [0004] In some situations the user has a frequent need to put on and take off the glasses from his eyes. This occurs particularly in the use of reading glasses, when the user has to observe alternately distant and near objects, and in the use of sunglasses, when there are sudden changes in light, for example when driving in the presence of tunnels.
    For convenience of use, it is desirable that, when the user is not looking through the lenses, the spectacles do not have to be stored, but can simply be worn by the user in a different position.
    [0006] A known solution is given by the use of a chain which joins the rods and allows the glasses to be worn around the neck. The temples of the glasses in particular are inserted in special slots in the chain.
    [0007] However, the same chain can be excessively long or excessively short depending on the physiognomy of the user. Too long chains can lead to large oscillations of the glasses around the user's neck when they move, with the risk that the glasses hit external objects.
    [0008] Furthermore, the eyeglass chains can easily catch and hold the eyeglasses. causing discomfort to the user's neck.
    [0009] The object of the present invention is to solve the above problems, in particular by limiting the possibility of movement of the glasses when worn around the neck, and therefore the risk of collisions.
    [0010] A further object of the invention is to allow spectacles to be worn around the neck avoiding the risk of the spectacles getting caught in external objects.
    [0011] These and other purposes are achieved by a pair of eyeglass extensions and a pair of spectacles in accordance with claims 1 and 11 set forth below.
    [0012] Advantageously, in the configuration of use, the second segments of each cap can rest behind the user's neck, supporting the glasses. Consequently, the glasses do not hang excessively from the neck, and its mobility is reduced. Furthermore, the glasses can be supported on the neck without the presence of elements that can get caught.
    [0013] Further characteristics and advantages of the pair of extensions (further also called "extension kit") for eyeglasses according to the present invention will result from the description given below of a preferred embodiment example, given by way of non-limiting example, with reference to the attached figures in which:figure 1 shows a perspective view of an eyeglass extension kit according to the present invention;figure 2 shows a perspective view of a detail of the kit of figure 1,figure 3 shows a sectional view of the detail of figure 2,Figures 4 and 5 show a sectional view of the detail of Figure 2 coupled to respective ends of eyeglass rods having different dimensions.
    [0014] With reference to the accompanying figures, 1 indicates as a whole an extension for glasses. The extension 1, which is further described below, is applicable to a pair of glasses 2.
    [0015] The glasses 2 comprises a front 3 and a pair of rods 4. The front 3 comprises at least one lens 31, as in the case of goggles, or more lenses 31, preferably two. The front can also comprise one or more hoops 32 to keep the lenses 31 in position, a bridge 33 that connects the rims 32, two nosepads 34 configured to rest on the nose of a user, and two noses 35 configured to connect to the rods 4. These characteristics are known to those skilled in the art and are therefore not further described below.
    [0016] The rods 4 are mirrored to each other. Each rod 4 is constrained to the front 3, for example in correspondence with one of the front ends 35. Preferably, each rod 4 is hinged to the front 3. Preferably, moreover, the rods 4 can be switched between a closed position, in which the rods 4 are approached to the front 3, and an opening position, in which the rods 4 are substantially parallel and spaced from each other in a longitudinal direction X.
    [0017] In the remainder of the description, where not specified, the directions and distances refer to the glasses with the rods 4 in the open position.
    [0018] In particular, each rod 4 comprises a stem 41 and a terminal 42. The stem 41 is substantially straight. The stem 41 is arranged between the front 3 and the respective terminal 42. The terminal 42 is therefore in a distal position with respect to the front 3. In the open position the rods 4, and in particular the rods 41, identify a plane of the rods 4 .
    [0019] The terminal 42 can have different shapes and sizes. The terminal 42 is generally defined by an end portion of the rod 4. If the stem 41 is made of metal, the terminal 42 may comprise a plastic coating (not shown), to improve contact with a user's head. .
    [0020] The terminal 42 can be inclined with respect to the stem 41 of the respective rod 4, and in the open position the terminal 42 extends outside the plane identified by the stems 41 of the rods 4. Preferably, each terminal 42 forms an angle obtuse with the stem 41 of the respective rod 4 so as to conform to the ear of a user.
    [0021] Each terminal 42 has an end portion 43. The end portion 43, or possibly the entire terminal 42, extends mainly along a prevalent direction of development Y. It should be noted that the terminals 42 of the rods 4 are extend in two distinct respective directions of prevalent development Y.
    [0022] According to the illustrated embodiment, the terminal 42 has an end portion 43 which is substantially flat. In other words, the end portion 43 has a cross section that identifies a first W and a second direction of section Z, orthogonal to each other and orthogonal to the prevailing development direction Y. In particular, the cross section of the end portion 43 extends in the second section direction Z for a shorter, that is negligible, length compared to a similar length in the first section direction W. Generally, the second section direction Z faces towards the user's head, so that the end portion 43 faces the user with a smooth surface.
    [0023] According to three different preferred standard types, terminals 42 have section dimensions, in particular in the first section direction W, equal to 3 mm, 5 mm, and 13 mm respectively.
    [0024] According to an aspect of the invention, two extensions 1 can be applied jointly to a pair of glasses 2, as shown in figure 1. The two extensions 1 have the same characteristics, and are mirrored to each other. In other words, the shape of any one of the extensions 1 can be obtained starting from the shape of the other extension 1 through a symmetry with respect to a plane.
    [0025] The two extensions 1 are distinct and separate elements from each other. The characteristics indicated for a single extension 1 or for single mirror parts of the glasses 2 are intended as applicable to both extensions 1 or to both the corresponding mirror parts of the glasses 2.
    [0026] Each extension 1 has a body 5. According to an embodiment, the body 5 is made of elastomeric material. More preferably, the body 5 is made of silicone rubber, made for example by molding starting from liquid silicone rubber molding. This material has several advantageous characteristics, including flexibility, resistance to rigid and high temperatures, to ultraviolet rays and to aging. Advantageously, this material can have a tensile elongation between 400% and 700%, a Shore hardness of type A 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>.
    [0027] 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 located on the first segment 53, and the second end 52 is located on the second segment 54.
    [0028] Each extension 1 is configured to be fixed to a respective terminal 42 of the eyewear 2. In particular, the first segment 53 can be fixed to the terminal 42.
    [0029] In the remainder of the description, if not specified, the reciprocal positions of the eyewear 2 and of the extensions 1 are intended with the two extensions 1 fixed to the respective terminals 42 (always with the rods 4 in the open position). In particular, the references relating to the prevailing development directions Y, to the first W and to the second Z direction of section refer to the position in which the two extensions 1 are fixed to the respective terminals 42.
    [0030] The first segment 53 extends mainly in the aforementioned prevailing development direction Y. Preferably, the first segment 53 has a cavity 55 configured to reversibly receive the terminal 42. In particular, the cavity 55 receives the terminal 42 along the prevailing development direction.
    [0031] The body 5 has an opening 56 at the first end 51 which can be crossed by the terminal 42 to allow the terminal 42 to be inserted into the cavity 55. The cavity 55 has a bottom 57 opposite the opening 56.
    [0032] Preferably, the opening 56 has a substantially elliptical shape to retain the terminal 42, in particular its end portion 43, and to prevent rotation of the extension 1 with respect to the terminal 42. In particular, the opening 56 it has larger dimensions in the first section direction W than its dimensions in the second section direction Z, similar to as already described in relation to the end portion 43 of the terminal 42.
    [0033] Advantageously, when the terminal 42 is inserted into the cavity 55 through the opening 56, the orientation of the extension 1 is fixed.
    [0034] Preferably, the opening 56 and / or the cavity 55 are elastically deformable to allow the insertion and retention of the terminal 42 in the cavity 55. Advantageously, it is necessary to apply a force by the user to remove the terminal 42 from the cavity, and the risk of it accidentally slipping off during use is prevented.
    [0035] According to the illustrated embodiment, the cavity 55 has a first portion 58. The opening 56 has smaller dimensions than the section dimensions of the first portion 58. In particular, the opening 56 has section dimensions, in particular measured in the first section direction W, equal to 3 mm. The first portion 58 of the cavity 55 has section dimensions, in particular measured in the first section direction W, equal to 5 mm.
    [0036] Advantageously, terminals 42 having section dimensions greater than the dimensions of the opening 56 can pass through the opening 56, which is deformable, and be housed in the first portion 58 of the cavity 56. In particular, terminals 42 with section dimensions of 5 mm can be housed in the first portion 58 without deforming the cavity 55. Instead, as shown in Figure 4, terminals 42 with section dimensions of 13 mm can be housed in the first portion 58 with deformation of the cavity 55.
    [0037] Preferably, the cavity 55 also has a second portion 59. located at the bottom 57 of the cavity 55. In other words, the first portion 58 of the cavity 55 is arranged between the opening 56 and the second portion 59 of the cavity 55. The opening 56 has the same dimensions with respect to the section dimensions of the second portion 59.
    [0038] Advantageously, as shown in Figure 5, terminals 42 having section dimensions smaller than or equal to the opening dimensions 56, for example equal to 3 mm, can be housed in the second portion 59 of the cavity 55 to avoid free movements in the cavity 55.
    [0039] Preferably, the extension 1 has a hole 11 to allow air to escape from the cavity 55 during the insertion of the terminal 42 into the cavity 55. Advantageously, the cavity 55 offers a low mechanical resistance to the insertion of the terminal 42.
    [0040] The second segment 54 is inclined with respect to the first segment 53. The second segment 54 extends along a prevalent development direction T. In particular, the second segments 54 extend along two respective prevalent development directions T, which are distinct from each other . In detail, the second segments 54 each have an extension between 2 cm and 8 cm, preferably equal to 3 cm.
    [0041] When the first segments 53 are each connected to the respective terminal 42, the second segments 54 protrude from the respective terminals 42. Furthermore, in this condition, the prevailing development directions T of the second segments 54 converge with each other, as shown in example in Figure 1, so that the second segments 54 can rest on the neck of a user.
    [0042] In particular, the distance between the terminals 42 is greater than the distance between the second segments 54 of the respective extensions 1. These distances are understood to be measured in the longitudinal direction X, and in particular in the plane of the rods 4, with the rods 4 in open position, and the terminals 42 connected to the first segments 53 of the respective extensions 1.
    [0043] Again in this configuration, each second segment 54 is inclined with respect to the respective first segment 53 by an angle B ranging from 110 ° to 160 °, measured on the plane identified by the two rods 4, or by the stems of rods 41. Such angle B in particular is identified by the projections of the first segments 53 and of the respective second segments 54 on this plane. In other words, the angle B is identified by the projections on the plane of the rods 4 of the prevailing development directions T of the second segments 54 and of the prevailing development directions Y of the respective terminals 42.
    [0044] Advantageously, while in the absence of extensions 1 the neck of a user can easily cross the space between the terminals 42 of the glasses 2, in the presence of extensions 1 there is no longer sufficient space for the neck to pass between the extensions 1, and the glasses do not fall off the neck.
    [0045] In order to ensure the orientation described above of the second segments 54 with respect to the terminals 42, or with respect to the first segments 53, it is noted that the prevailing development direction T of each second segment 54 lies in a plane substantially orthogonal to the first section direction W of the respective terminal 42, or of the respective first segment 53.
    [0046] Advantageously, as described above, rotation of the extension 1 with respect to the terminal 42 is prevented. Consequently, the orientation of the second segment 54 is fixed. In particular, when the user wears the glasses around his neck, this orientation is at least partially turned behind the user's neck even if, in not illustrated embodiments of the invention, the second segment 54 can also develop partially downwards. , i.e. behind the user's back.
    [0047] The extension kit 1 according to the invention can be used, in conjunction with the eyewear 2. by first fixing each extension 1 to the respective terminal 42. In particular, fixing takes place by inserting the end portion 43 of the terminal 42 into the cavity 55 through the opening 56. On insertion, the extension 1 is oriented with respect to the terminal 42 thanks to the substantially flat shape of the end portion 43 of the terminal 42 and to the elliptical shape of the opening 56.
    [0048] Subsequently, a user can wear the glasses 2 with the extensions 1 on the face, with the terminals 42 resting on the ears, or they can wear the glasses 2 around the neck, with the second segments 54 of the extensions 1 rest behind the neck.
