Abstract

The present invention relates to an eyeglasses with one arm (1) on the left and on the right side and with on each side one connector element (8) of a mount (7), where on the connector element (8) joint elements (11, 13) are positioned which work together with joint elements (6) positioned on the end of the arm (1) close to the mount, forming a rotary joint. The arm (1) has on its end close to the mount at least two fingers (2, 3) in its longitudinal direction, which exert a spring action in the direction of the joint axis of the rotary joint.

Claims

1. A glasses frame with one arm (1) on the right and on the left sides and with a mount (7), which has one connector element (8) each on the left and right, the end of which close to the arm points, when unfolded, in the direction of the arm (1), so that on the connector element (8) there are joint elements (11, 13) positioned, which work with joint elements (6) positioned on the end of the arm (1) toward the mount, forming a rotary joint, and so that the arm (1) on its end toward the mount has at least two fingers (2, 3) in its longitudinal direction, which are so configured that they exert spring action essentially in the direction of the joint axis of the rotary joint, which spring action holds the joint elements (6, 11;

13) of the arm (1) and of the connector element (8) in a rotatable and secure connection, characterized in that the fingers (2, 3) of the arm consist of leaf springs whose leaf surface, when the arm (1) is unfolded, runs essentially in the plane of the connector element (8) belonging to the arm (1).

2. A glasses frame according to claim 1, wherein the spring action consists in the fact that the spring action exerted by one finger (2 or 3) acts in the direction toward the other finger (3 or 2).

3. A glasses frame according to claim 2, wherein the connector element (8) is continuously divided into an upper brace (9) and a lower brace (10).

4. A glasses frame according to claim 3, wherein the division of the connector element (8) extends through the mount (7) as far as the glasses lenses received by the mount (7).

5. A glasses frame according to any one of claims 1 to 4, wherein the joint elements of the arm (1) are loops (6) mounted on the fingers (2, 3) and the joint elements of the connector element (8) are pivot studs (11) which engage in the loops (6).

6. A glasses frame according to any one of claims 1 to 4, wherein the joint elements of the arm (1) are bearing bushes attached to the fingers and the joint elements of the connector element (8) are pivot studs (13), which are mounted in the bearing bushes.

7. A glasses frame according to claim 1, wherein the spring effect consists in the fact that the spring force exerted by one finger (2 or 3) acts in the direction moving away from the other finger (3 or 2).

8. An eyeglasses frame according to claim 7, wherein the joint elements of the connector element (8) are loops and the joint elements of the arm (1) are pivot studs applied on the fingers of the arm (1) which engage in the loops.

9. An eyeglasses frame according to any one of the foregoing claims, wherein the fingers consist of three leaf springs (2, 3, 4).

10. A glasses frame according to claim 9, wherein the connector element (8) is configured in such a way that it forms an abutment (12) for the center (4) of the three leaf springs of an arm (1) belonging to the connector element (8) when the arm (1) is folded up.

11. A glasses frame according to either of claims 9 or 10, wherein the length of the leaf springs (2, 3, 4) of the arm (1) and the length of the abutment (12) are selected so that the spring effect is sufficient to achieve a secure connection of the joint elements (6, 11;

13) of the arm (1) and of the connector element (8) and in addition the leaf spring effect of the center leaf spring (4) of the arm (1) is sufficient to keep the arm (1) in its folded position.

12. A glasses frame according to any one of claims 9 to 11 and either of claims 3 or 4, wherein the length of the leaf springs (2, 3, 4) of the arm (1) and the length of the abutment (12) are selected so that the spring action is sufficient to achieve the holding together of the two braces (9, 10) of the connector element (8) and in addition the leaf spring effect of the center leaf spring (4) of the arm (1) is sufficient to keep the arm (1) in its folded position.

13. A glasses frame according to any one of claims 10 to 12, wherein the abutment (12) is configured in the shape of a leaf.

14. A glasses frame according to any one of claims 11 to 13, wherein the abutment (12) extends from the joint elements (11, 13) of the connector element (8) in the direction toward the arm (1) in unfolded position in such a way that upon folding of the arm (1) the outer leaf springs (2, 3) of the arm (1) extend outward over the abutment (12).

15. A glasses frame according to any one of the foregoing claims, wherein a collar is provided, which before installation of the arm (1) can be slid up over the connector element (8) belonging to the arm (1).

16. A glasses frame according to any one of the foregoing claims, wherein all parts are produced from sheet metal and/or titanium.
