Abstract
A clasp is described that is lockable in both an open and a closed position. In the locked open position the clasp can be manipulated without concern for the clasp unintentionally closing before it can receive the end of a chain, such as a necklace or the like. Pushing a button on the clasp closes and locks the clasp. The clasp remains locked in the closed position until the button is pressed and the clasp is pulled open.
Claims38
A clasp for jewelry comprising:
- a body having a first opening, a second opening, and an internal space;
- a connector fixed to the body for linking to a chain;
- a movable connector, inseparable from the body, movable to a locked closed position by a first spring and movable to a locked open position by an external force, the movable connector extends through the first opening and includes a first latch piece within the internal space of the body;
- one or more guides in the internal space;
- and
- a button extends through the second opening and is movable along the one or more guides, the button includes a second spring and a second latch piece that interfaces with the first latch piece, the button includes two positions, in a first position the second latch piece locks with the first latch piece, in a second position the second latch piece and the first latch piece disengage and the movable connector can be moved by an external force allowing the second spring to move the second latch piece to a position that keeps the movable connector in a locked open position.

- a movable connector, inseparable from the body, movable to a locked closed position by a first spring and movable to a locked open position by an external force, the movable connector extends through the first opening and includes a first latch piece within the internal space of the body;
- one or more guides in the internal space;
- and
- a button extends through the second opening and includes a second latch piece movable along the one or more guides that locks with the first latch piece in the locked closed position and in the locked open position, the second latch piece having a first position, a second position and a third position, the first position is held in the locked closed position by a second spring that forces the second latch piece to interface with the first latch piece, the second position causes the first and second latch pieces to disengage allowing the movable connector to be moved by the external force to the open position, and the third position, held by force from the second spring, causes the second latch piece and the first latch piece to engage resulting in the locked open position.

A clasp for jewelry comprising:
- a body having an internal space, a first opening and a second opening generally perpendicular to each other;
- a connector fixed to the body for linking to a chain;
- a movable connector, inseparable from the body, movable to a locked closed position by a first spring and movable to a locked open position by an external force, the movable connector extends through the first opening and includes a first piece within the internal space of the body, the first piece is L-shaped and includes a first latch;
- one or more guides in the internal space;
- and
- a button having a shaft that extends through the second opening, the shaft of the button connected to a second piece perpendicular to the button and including a second spring, the second piece interfaces with the one or more guides and includes a second latch for interfacing with the first latch, the button includes a first position and a second position held place by the second spring, in the first position the second latch interfaces with the first latch locking the movable connector in the closed position, and in the second position the second latch and the first latch disengage, allowing the movable connector to be moved by an external force to the open locked position.

A clasp for jewelry comprising:
- a body having an internal space, a first opening and a second opening generally perpendicular to each other;
- a connector fixed to the body for linking to a chain;
- a movable connector inseparable from the body extends through the first opening;
- an L-shaped piece connected to the movable connector located within the internal space of the body and including a first latch;
- a first spring between the L-shaped piece and an internal wall of the body, the first spring in a position to energize the movable connector and the L-shaped piece to a locked closed position and resist a locked open position;
- one or more guides in the internal space;
- a button extends through the second opening;
- a second piece that interfaces with the one or more guides and is connected to the button at a angle perpendicular to the button, the second piece includes a second latch for interfacing with the first latch when the movable connector is in the locked closed position;
- and
- a second spring between the second piece and an internal wall of the body, the second spring positioned to energize the second piece in a direction to interface the second latch with the first latch in the locked closed position, and the second spring energizing the second piece further in the direction to connect an end of the second piece with the L-shaped piece in the locked open position.
