A recently filed patent (Publication Number: US20230263275A1) describes a new type of jewelry clasp that aims to provide a secure and convenient way to fasten bracelets or necklaces. The jewelry clasp consists of two parts, with at least one part containing a magnet and the other part being magnetically attractable. This magnetic attraction holds the clasp parts together when in the attached position.

The clasp also includes a slider that can be moved between a releasing state and a locking state. In the releasing state, the first clasp part can be detached from the second clasp part, while in the locking state, the first clasp part is prevented from being detached. The slider operates through the use of tongues sliding in grooves.

Additionally, the clasp features a snap lock mechanism that engages the slider and the housing. This mechanism allows for easy sliding of the slider between the locking and releasing states by applying force in the sliding direction. The snap lock includes a spring-biased part and a depression on the slider, which securely holds the parts together.

The patent also describes various configurations and features of the clasp, such as the use of multiple magnets, the positioning of magnets in different parts of the clasp, and the use of a cut-out and axial end walls to limit the sliding movement of the slider.

Furthermore, the patent covers the use of this jewelry clasp in a piece of jewelry, where the first clasp part is attached to one end of an elongated member (bracelet or necklace) and the second clasp part is attached to the other end. This ensures that the clasp securely holds the two ends together when the first clasp part is in the attached position.

The patent also provides methods for closing and opening the jewelry clasp. To close the clasp, the first clasp part is inserted into the housing and the slider is moved to the locking state. To open the clasp, the slider is moved to the releasing state, allowing the first clasp part to be detached, and a force is exerted to overcome the magnetic attraction and remove the first clasp part from the housing.

Overall, this patent introduces a new and innovative jewelry clasp design that aims to provide a secure and user-friendly fastening mechanism for bracelets and necklaces.
