Abstract

An eye glass frame temple is provided having a pole head portion, a leg portion rotatably coupled to the pole head portion, and a spring loaded pin for exerting a force against the leg portion when the leg is rotated a predetermined amount and in a predetermined first direction relative to the pole head portion. The force can cause the leg portion to rotate in a second direction opposite the first direction.

Claims

1. An eye glass frame temple comprising:

a pole head portion;

a jacket comprising an opening;

a leg portion extending from the jacket and pivotally coupled to the pole head portion;

a pin slidably coupled to the jacket and having a portion extendable beyond the jacket for engaging the pole head portion.

2. A temple as recited in claim 1 wherein the pin is slidably fitted within the jacket opening, the temple further comprising a spring within the jacket opening urging the pin to extend beyond the jacket.

3. A temple as recited in claim 2 wherein the leg portion is welded to an end of the jacket opening sandwiching the spring between the leg portion and the pin.

4. A temple as recited in claim 1 wherein the jacket opening comprises:

a first diameter section; and

a second diameter section extending coaxially from the first diameter section and having a diameter greater than the first diameter section, wherein an annular shoulder is defined between the first and second opening sections.

5. A temple as recited in claim 4 wherein the pin comprises:

a first section having a diameter smaller than the diameter of the opening first section; and

a second section extending coaxially from the first section and having a diameter smaller than the diameter of the opening second section and greater than the diameter of the opening first section, and wherein the pin first section is slidably fitted within the opening first section and wherein the pin second section is slidably fitted within the opening second section.

6. A temple as recited in claim 5 further comprising a spring fitted within the second opening section for urging the pin to extend beyond the jacket.

7. A temple as recited in claim 6 wherein the spring is sandwiched between the pin second section and the leg portion.

8. A temple as recited in claim 1 wherein the leg portion is fitted within the jacket opening and wherein a bracket is welded to the jacket and to the leg portion.

9. An eye glass frame temple comprising:

a pole head portion;

a leg portion rotatably coupled to the pole head portion; and

a spring loaded pin coupled to the leg portion for releasably engaging the pole head portion when the leg portion is rotated a predetermined amount and in a predetermined direction relative to the pole head portion.

10. A temple as recited in claim 9 comprising a spring coupled to the pin, wherein said spring is compressed by the pin generating a spring force when the leg portion is rotated said predetermined amount in said predetermined direction.

11. An eye glass frame temple comprising:

a pole head portion;

a leg portion;

a jacket comprising an opening, said jacket extending from one of said pole head and leg portions;

a hinge pivotally coupling the jacket to the other of said pole head and leg portions;

a pin slidably coupled to the jacket and having a portion extendable beyond the jacket for engaging said other of said pole head and leg portions.

12. A temple as recited in claim 11 wherein the pin is slidably fitted within the jacket opening, the temple further comprising a spring within the jacket opening urging the pin to extend beyond the jacket.

13. A temple as recited in claim 11 wherein the jacket opening comprises:

a first diameter section; and

a second diameter section extending coaxially from the first diameter section and having a diameter greater than the first diameter section, wherein an annular shoulder is defined between the first and second opening sections.

14. A temple as recited in claim 13 wherein the pin comprises:

a first section having a diameter smaller than the diameter of the opening first section; and

a second section extending coaxially from the first section and having a diameter smaller than the diameter of the opening second section and greater than the diameter of the opening first section, and wherein the pin first section is slidably fitted within the opening first section and wherein the pin second section is slidably fitted within the opening second section.

15. A temple as recited in claim 14 further comprising a spring fitted within the second opening section for urging the pin to extend beyond the jacket.

17. A temple as recited in claim 16 further comprising a spring coupled to the pin, wherein said spring is compressed by the pin generating a spring force when the leg portion is rotated said predetermined amount in said predetermined direction.

16. An eye glass frame temple comprising:

a pole head portion;

a leg portion rotatably coupled to the pole head portion; and

a spring loaded pin coupled to the pole head portion for releasably engaging the leg portion when the leg portion is rotated a predetermined amount and in a predetermined direction relative to the pole head portion.
