Eyeglasses with extensions

1. Eyeglasses, comprising:

a frame front;

a pair of temples, wherein each temple is attached to the frame front and has a respective temple tip; and

a pair of extensions configured to be removably fixed each to a respective temple tip, wherein each extension comprises a body extending between a first end and a second end;

each body comprising:

a first substantially rigid segment configured to be fixed to the respective temple tip, the first substantially rigid segment of each extension having a cavity configured to receive the respective temple tip;

an opening at the first end configured to be passed through by the respective temple tip to allow insertion of the respective temple tip into the cavity and removal therefrom; and

a second substantially rigid segment inclined with respect to the first substantially rigid segment and extending along a respective main direction of extension;

wherein when the first substantially rigid segments are connected each to the respective temple tip, the second substantially rigid segments project from the respective temple tips, and the main directions of extension of the second substantially rigid segments converge with each other so that the second substantially rigid segments can rest on a neck of a user,

wherein the cavity has a first portion and a second portion, wherein the first portion of the cavity is arranged between the opening and the second portion of the cavity,

wherein the opening has section dimensions in width and height smaller than the section dimensions in width and height of the first portion, and

wherein the second portion has section dimensions in width and height smaller than the section dimensions in width and height of the first portion.

2. The eyeglasses of claim 1 , wherein each extension has a hole to allow air to exit from the cavity during the insertion of the respective temple tip.

3. The eyeglasses of claim 1 , wherein the opening and/or the cavity are elastically deformable to allow insertion and retention of the respective temple tip in the cavity.

4. The eyeglasses of claim 1 , wherein the opening of each extension has an elliptical shape.

5. The eyeglasses of claim 1 , wherein each cavity has a bottom opposite the opening, and

wherein the second portion is located at the bottom.

6. The eyeglasses of claim 1 , wherein each opening has the same section dimensions in width and height as the section dimensions in width and height of the second portion of the cavity.

7. The eyeglasses of claim 1 , wherein the body of each extension is made of elastomeric material.

8. The eyeglasses of claim 1 , wherein each second substantially rigid segment has an extension between 2 centimeters (cm) and 8 cm.

9. The eyeglasses of claim 1 , wherein the distance between the temple tips is greater than the distance between the second substantially rigid segments of the respective extensions when the eyeglasses are in an open, as-worn position.

10. The eyeglasses of claim 1 , wherein each second substantially rigid segment is inclined with respect to a respective first substantially rigid segment by an angle between 110° to 160°, measured on a plane defined by the two temples.

11. The eyeglasses of claim 1 , wherein each temple tip has a substantially flat end portion, and

wherein the opening of each extension has an elliptical shape to hold the end portion and to prevent rotation of the extension with respect to the respective temple tip.

12. The eyeglasses of claim 1 , wherein the opening and the second portion of the cavity each define a narrowing of the cavity with respect to the first portion of the cavity.

13. The eyeglasses of claim 1 , wherein the first portion of the cavity defines a first seat configured to receive temple tips of a wide type,

wherein the second portion of the cavity defines a second seat configured to receiving temple tips of a thin type, and

wherein the cavity is shaped to prevent access of the temple tips of the wide type to the second portion of the cavity.

14. The eyeglasses of claim 13 , wherein the first portion of the cavity is deformable to receive the temple tips of the wide type.

15. A pair of eyeglasses, comprising:

first eyeglasses of claim 13 ; and

second eyeglasses of claim 13 ;

wherein the first eyeglasses have temple tips of the wide type and the second eyeglasses have temple tips of the thin type, and

wherein the temple tips of the first eyeglasses have section dimensions in width and height greater than the section dimensions in width and height of the temple tips of the second eyeglasses.

16. The eyeglasses of claim 1 , wherein each second substantially rigid segment has an extension equal to 3 centimeters (cm).

17. A pair of eyeglasses, comprising:

first eyeglasses of claim 14 ; and

second eyeglasses of claim 14 ;

wherein the first eyeglasses have temple tips of the wide type and the second eyeglasses have temple tips of the thin type, and

wherein the temple tips of the first eyeglasses have section dimensions in width and height greater than the section dimensions in width and height of the temple tips of the second eyeglasses.

18. The eyeglasses of claim 1 , wherein the opening defines a narrowing of the cavity with respect to the first portion of the cavity.

19. The eyeglasses of claim 1 , wherein the second portion of the cavity defines a narrowing of the cavity with respect to the first portion of the cavity.

20. The eyeglasses of claim 1 , wherein the first portion of the cavity defines a first seat configured to receive temple tips of a wide type, and

wherein the second portion of the cavity defines a second seat configured to receiving temple tips of a thin type.
