A jewelry clasp is disclosed and includes a first part including a first magnet, a first groove and a first catch and a second part including a second magnet, a second groove and a second catch. The first and second magnets generate an attractive force holding the first part to the second part, the first catch is received in the second groove and the second catch is received in the first groove. A relief disposed on at least one of the first part and the second part at an interface between the first part and the second part is provided to aid in releasing the first part from the second part.

A connection structure and a wearing device are provided. The connecting structure includes a connecting member, a latching member, an engaging member, and an elastic member; one of two ends of the latching member is rotatably connected with the connecting member, and the other end of the latching member is provided with a latching portion; the engaging member is provided with an engaging portion corresponding to the latching portion, and the elastic member can engage the latching portion with the engaging portion. The wearing device includes the connection structure. The latching member is rotatably connected with the connecting member so as to enable the latching member to be quickly separated from the engaging member, and two mechanisms could be connected and separated from each other quickly with the connection structure.

Watch case including: a middle; at least one pair of horns intended to retain a wristwatch strap portion; the middle including a first lock member; and a second lock member mounted on the pair of horns and complementary to the first member to lock the pair of horns to the middle. The case also includes a manipulation member that can be manipulated by a user in order to move the second member between a locking position in which the members co-operate to maintain the pair of horns on the middle and a release position in which the pair of horns can be detached from the middle.

A jewelry closure mechanism (e.g., clasp) may include a locking receptacle and a locking pin that operate together to provide a closure mechanism for a piece of jewelry. The closure mechanism may or may not include a hinge. In some implementations, a locking pin may extend from the second arm and be inserted into a locking receptacle formed in a second arm to lock the two components together. The locking receptacle may include one or more wires (e.g., spring and/or precast) that extend transversely to the direction of the locking receptacle. The closure mechanism may be used as a general jewelry closure device and/or to couple segments of jewelry together.

A magnetic jewelry attachment assembly for selectively coupling mechanical clasps at opposite free ends of an article of jewelry, including a pair of clasp-retaining cases magnetically-couplable to each other. Each clasp-retaining case incorporates an elongated clasp-retaining body having a clasp-receiving channel extending into a proximal end of the elongated clasp-retaining body, the clasp-receiving channel extending from a proximal channel end to a distal channel end, the distal channel end terminating within the elongated clasp-retaining body. A clasp securement device is provided mounted within the distal channel end of the elongated clasp body-retaining and configured for releasably-engaging a first mechanical clasp at a first one of the opposite free ends of the article of jewelry. An elongated clasp-retaining body magnetic portion enable the pair of clasp-retaining cases to be selectively magnetically coupled to one another to form a composite clasp-retaining case that securely retains the opposite free ends of the article of jewelry while obscuring the respective mechanical clasps of the article of jewelry from view.

A removable module and a housing for an attachment system of a consumer product is described. The removable module includes a locking mechanism comprising a first portion having a substantially planar top surface and second portion that comprises a substantially non-planar bottom surface. The first portion and the second portion are coupled together. The locking mechanism also includes a first spring mechanism coupled between the first portion and the second portion. The first spring mechanism causes the first portion to be biased away from the second portion. The locking mechanism also includes a second spring mechanism. The second spring mechanism causes the substantially planar top surface of the first portion to be biased substantially flush with respect to the removable module and also causes the substantially non-planar bottom surface of the second portion to be biased proud with respect to the removable module.

An electronic device includes a housing forming an enclosed chamber. The housing has a top portion and a bottom portion. One or more sensors is provided within the chamber and configured to interface with a user to generate physiological data associated with the user. A set of electrodes is provided on the bottom portion of the housing. Each electrode in the set of electrodes is a single member having a corresponding inner electrode portion within the chamber and an outer electrode portion outside the housing. A set of magnets is provided on the bottom portion of the housing.

Described is a fastening device for jewellery comprising a first element and a second element which can be fixed to respective ends of jewellery, wherein the first element has a top surface and a bottom surface, in which a socket is formed; the second element has a top surface, a bottom surface and a head, configured to interlock in a complementary way with the socket, so as to reversibly couple the first element with the second element; the second element comprises a groove, formed on its top surface, in which a sliding slider is housed, the first element comprises a recess, in a position adjacent to the socket, delimited by its top surface, so that, when the head is inserted in the socket, the slider remains in contact with the top surface of the first element at the recess, preventing the head from disengaging the socket and the second element from separating from the first element.

A clasp mechanism is disclosed. Example embodiments are directed to a clasp mechanism comprising: an outer tube; an end cap attached at a top of the outer tube; an inner tube encompassed by the outer tube; a spring and a plate captured between the end cap and a top of the inner tube; a slotted end-cap at the bottom of the outer tube; and a hook configured for insertion into a slot of the slotted end-cap, to latch to the top of the inner tube, and to be held in place by the spring and plate.

An anti-disassemble watch buckle includes a bottom housing and a top housing with an in-between space for accommodating a first strap, wherein the anti-disassemble watch buckle has a first end and a second end being opposite to the first end; and a cantilever snap with a back end fastened to the bottom housing at the first end, and a front end hung in the space.
