Description

Insert for a pad or nose piece of a spectacle frame

Technical Field

The present invention relates to an insert for a pad or nose pad of an eyeglass frame (eyeglass frame).

Background

Eyeglasses generally consist of a frame consisting of two rims (eyewires) whose function is to keep the lenses in the correct position, a bridge (bridge) connecting the two rims, two flexible pads (soft pads) or nose pads associated with the bridge by means of rigid inserts projecting from the bridge, and two temples with hinges connected to the rims.

Now, nose pads are known made of substantially flexible plastic material, making them substantially tear-drop shaped with the rounded top (rounded vertex) oriented downwards, allowing it to rest comfortably on the root of the nose.

It is known that the insert of the nose pad is made of a metal material or a rigid plastic material, so as to be able to couple the nose pad to the bridge of the spectacle frame; the insert comprises a substantially flat appendix (apron) made of metal material or rigid plastic embedded in the nose pad, a stem (shank) projecting from the appendix, which can be associated with a pad holder, which in turn can be associated with the spectacle frame.

The connection between the pad holder and the handle typically occurs by way of a lateral pivoting of the pad holder on the handle in order to allow the nose pads to swing, thereby improving the adaptation to the shape of the nasal root.

However, such conventional solutions have a drawback: the swinging of the nose pad is practically limited to one plane, and furthermore, the rotation angle that can be given to the nose pad is also limited, and this does not enable the nose pad to achieve optimal adaptation to various shape structures of the nose root of different users.

There is another disadvantage: in conventional solutions, if the spectacle frame is shaken, there is a problem of noise emission from the pad or nose pad; even if the noise is reduced, the mobility of the pad or nose pad of the conventional system still generates a certain amount of noise if the eyeglass frame is shaken, and this noise is generated by the impact of the insert of the pad against the wall of the pad holder.

In high-end eyewear, this noise can be annoying to the user and thus frustrate purchase.

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to eliminate the above drawbacks by providing an insert for a nose pad of a spectacle frame which makes it possible to achieve an optimal adaptation of the nose pad to the various shapes of the structure of the root of the nose of each user.

Within this aim, an object of the invention is to obtain an insert that makes it possible to limit the noise between the pad or nose pad and the pad holder in the case of a rocking of the spectacle frame.

Another object is to provide an insert that is structurally simple and low-cost and that can be made with generally conventional systems.

This aim and these and other objects that will become better apparent hereinafter are achieved by a rigid insert for a flexible cushion or nose pad, comprising a shank partially embedded in said cushion or nose pad, characterized in that the free end of said shank is substantially rectangular in plan view, said free end of said shank delimiting two mutually opposite first hemispherical lateral surfaces and two mutually opposite second planar lateral surfaces, said shank being connectable to a complementary-shaped cushion holder that can be associated with the frame of an eyeglasses frame and has a pair of first side walls that pivot with respect to said two mutually opposite first hemispherical lateral surfaces by means of a friction control.

Detailed Description

In the embodiments shown below, the individual characteristics shown in connection with the specific examples may actually be interchanged with other different characteristics that exist in other embodiments.

With reference to the figures, the reference numeral 1 generally designates a rigid insert, made substantially of metal material or rigid plastic, which can be connected to a flexible pad or nose pad 2, substantially tear-drop shaped.

The insert 1 comprises a substantially flat appendix 3, the appendix 3 preferably having a substantially oval or similar shape to that of the nose piece 2 in plan view, but of smaller dimensions and being embedded in the nose piece 2.

Projecting from the appendix 3 to the outside of the nose pad 2 is a stem 4, the free end 5 of which has a substantially rectangular shape in plan view and defines two mutually opposite first hemispherical lateral surfaces 6a, 6b and two mutually opposite second flat lateral surfaces 7a, 7 b.

The stem 4 can be coupled to a complementary shaped pad holder 8, the pad holder 8 being constituted by an open subframe having a substantially rectangular shape in plan view, so as to delimit a rear wall 9, the rear wall 9 being connected to the frame of the spectacle frame by a wire 10, and a pair of side walls 11a, 11b diverging from the rear wall, the side walls 11a, 11b being connected to a pair of front appendages 12a, 12b, the front appendages 12a, 12b lying on the same plane, having free ends facing each other.

Thus, the pad holder 8 has an open rather than closed shape structure, wherein a certain amount of play is allowed between the facing free ends of the pair of front attachments 12a, 12b, which enables a friction-controlled connection with the shank 4.

The inner side surface 13 of the rear wall 9 and the inner side surfaces 14a, 14b of the pair of front appendages 12a, 12b are complementary in shape to the mutually opposite second flat side surfaces 7a, 7b and face the mutually opposite second flat side surfaces 7a, 7 b.

In contrast, the inner side surfaces 15a, 15b of the pair of side walls 11a, 11b are complementary in shape to the mutually opposed first hemispherical side surfaces 6a, 6b and are arranged in contact with the mutually opposed first hemispherical side surfaces 6a, 6 b.

The operation is as follows: the insert, which shapes the inner side surfaces 15a, 15b of the pair of side walls 11a, 11b complementarily to the mutually opposed first hemispherical side surfaces 6a, 6b and is arranged in contact with the mutually opposed first hemispherical side surfaces 6a, 6b, achieves a friction-controlled coupling, which makes it possible to achieve a movement of the nose pad 2 in a plurality of directions, as shown in fig. 6 to 16, and with a much greater displacement factor than that achievable by the prior art.

The facing free ends of the pair of front attachments 12a, 12b can in fact vary the distance between them according to the desired movement imposed on the nose pads, while maintaining the connection between the pad holder 8 and the stem 4.

The nose pad 2 is thus movable in different directions and planes, while not being free to disengage from the pad holder 8.

For example, the rotation shown in fig. 6 and 7 may be up to about eight degrees; thus, again by way of example, the rotations shown in fig. 8-11 may be up to about twenty degrees; thus, again by way of example, the rotation shown in fig. 12-16 may be up to about eight degrees.

It has thus been found that the invention fully achieves the intended aim and objects, an insert 1 for a nose pad 2 of a spectacle frame has been obtained which enables a nose pad to be optimally adapted to the various shaped structures of the nasal root of each user, thanks to the wide range of adjustment that can be obtained of the position of the nose pad with respect to the pad holder.

Furthermore, the insert makes it possible to limit the noise between the pad or nose pad and the pad holder in the event of the spectacle frame shaking.

Finally, the insert also has the advantage of being simple in construction, low in cost, and can be provided with commonly known systems.

The present invention is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

Naturally, the materials used, as well as the dimensions, of the various parts of the invention may be more pertinent according to specific requirements.
