Eyeglasses

1. A glasses frame with one arm on the right and on the left sides and with a mount, which has one connector element each on the left and right, the end of which close to the arm points, when unfolded, in the direction of the arm, so that on the connector element there are joint elements positioned, which work with joint elements positioned on the end of the arm toward the mount, forming a rotary joint, and so that the arm on its end toward the mount has at least two fingers 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 of the arm and of the connector element in a rotatable and secure connection, characterized in that the fingers of the arm comprise leaf springs whose leaf surface, when the arm is unfolded, runs essentially in the plane of the connector element belonging to the arm; wherein the fingers form three leaf springs.

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

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

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

5. A glasses frame according to claim 1 , wherein the joint elements of the arm are loops mounted on the fingers and the joint elements of the connector element are pivot studs which engage in the loops.

6. A glasses frame according to claim 1 , wherein the joint elements of the arm are bearing bushes attached to the fingers and the joint elements of the connector element are pivot studs, 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 acts in the direction moving away from the other finger.

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

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

10. A glasses frame according to claim 9 , wherein the length of the leaf springs of the arm and the length of the abutment are selected so that the spring effect is sufficient to achieve a secure connection of the joint elements of the arm and of the connector element and in addition the leaf spring effect of the center leaf spring of the arm is sufficient to keep the arm in its folded position.

11. A glasses frame according to claim 10 , wherein the length of the leaf springs of the arm and the length of the abutment are selected so that the spring action is sufficient to achieve the holding together of the two braces of the connector element and in addition the leaf spring effect of the center leaf spring of the arm is sufficient to keep the arm in its folded position.

12. A glasses frame according to claim 11 , wherein the abutment is configured in the shape of a leaf.

13. A glasses frame according to claim 12 , wherein the abutment extends from the joint elements of the connector element in the direction toward the arm in unfolded position in such a way that upon folding of the arm the outer leaf springs of the arm extend outward over the abutment.

14. A glasses frame according to claim 13 , wherein a collar is provided, which before installation of the arm can be slid up over the connector element belonging to the arm.

15. A glasses frame according to claim 14 , wherein all parts are produced from sheet metal and/or titanium.

16. A glasses frame with one arm on the right and on the left sides and with a mount, which has one connector element each on the left and right, the end of which close to the arm points, when unfolded, in the direction of the arm, so that on the connector element there are joint elements positioned, which work with joint elements positioned on the end of the arm toward the mount, forming a rotary joint, and so that the arm on its end toward the mount has at least two fingers 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 of the arm and of the connector element in a rotatable and secure connection, characterized in that the fingers of the arm comprise a surface in the longitudinal direction of the arm, when the arm is unfolded, that runs essentially in the plane of the connector element belonging to the arm; wherein the arm forms a leaf spring at the end of the arm toward the mount that has a leaf surface that runs essentially in the plane of the connector element belonging to the arm when the arm is unfolded and that exerts a force in a direction perpendicular to the leaf surface against the connector element.
