Abstract
A piece of jewelry includes a hinge assembly that always biases two rigid portions to rotate relative to each other toward a closed secure position. The jewelry includes a leaf spring that biases a spring housing to rotate and thereby in turn rotate the two rigid portions relative to each other. The jewelry includes a pin in slot system which limits movement of the hinge to maximum predetermine opening angle.
Claims22
A piece of jewelry, comprising:
- a) a first rigid portion of a band element;
- b) a second rigid portion of the band element rotatably coupled to the first rigid portion at a first pivot point, the first and second rigid portions together adapted to at least substantially extend about a portion of a user's body when in a closed position;
- c) a spring housing having a first end and a second end, the first end rotatably coupled to the second rigid portion;
- d) a stopper pin;
- and
- e) a spring received in the spring housing and urging the second end of the spring housing toward the second rigid portion, wherein the second end of the spring housing and the first rigid portion are longitudinally displaceable relative to each other and coupled by the stopper pin,
- wherein the stopper pin limits angular rotation of the first rigid portion and the second rigid portion relative to each other.

A piece of jewelry, comprising:
- a) a rigid first jewelry portion having a hinge end;
- b) a rigid arm having a first end and a free end;
- c) a hinge about which the first end of the rigid arm is rotatable relative to the hinge end of the rigid first jewelry portion;
- d) a track portion at the hinge end of the rigid first jewelry portion, the track portion defining an elongate slot;
- e) a stopper pin;
- f) a spring housing having a first end and a second end, the first end of the spring housing rotatably coupled to the rigid arm, and the second end of the spring housing coupled to the track portion at the elongate slot with the stopper pin such that the second end of the spring housing is longitudinally displaceable relative to the track portion;
- g) a spring biasing the spring housing toward the rigid arm which, in turn, biases the rigid arm to rotate about the hinge toward a closed position.

A piece of jewelry, comprising:
- a) a rigid first jewelry portion having a hinge end;
- b) a rigid arm having a first end and a free end;
- c) a hinge about which the rigid arm is rotatable relative to the hinge end of the rigid first jewelry portion;
- d) a spring housing having a first end and a second end, the first end of the spring housing rotatably coupled to the rigid first jewelry portion, and the second end of the spring housing provided with a track portion having an elongate slot;
- e) a stopper pin extending through the elongate slot and coupling the first end of the rigid arm to the track portion of the spring housing;
- f) a leaf spring biasing the spring housing toward the rigid first jewelry portion which, in turn, biases the rigid arm to rotate about the hinge toward a closed position.
