A jewelry clasp for securing a first end of an elongated member of a bracelet or a necklace to a second end of the elongated member comprises a female part and a male part. One of the female and male parts comprises a first magnet and the other of the female and male parts comprises a part magnetically attractable by the first magnet. The female part comprises a housing and a hinged lid, the hinged lid being pivotable between a locking state and a releasing state and comprising the first magnet or the part magnetically attractable by the first magnet. When the female part is open, the male part can be inserted in an axial direction into the housing, and when the female part is closed and the male part is inserted into the housing, the male part is locked to the female part.

A sleeve and/or cuff holder apparatus is configured to prevent a sleeve or cuff of a shirt or other wearable garment from covering the face of a wearable device on a user's wrist, such as a watch, smart watch, wrist band, medical device, and/or other wrist accessory. Methods of using the same are further provided.

The invention discloses a universal connector, a method of making it, and a method of using it, by example. In a first embodiment, a universal connector is disclosed comprising an improved carabiner that incorporates a magnet into its structure. The carabiner magnet has a force of attraction of at least 2 kilograms to enable it to connect to any magnetic material. A second of many possible embodiments discloses the addition of hook and loop tape (i.e. a Velcro® strip) to enable the universal connector to connect to any other article having hook and loop tape. A third possible embodiment discloses the addition of a loop for connection to any strap or keychain, for example. A fourth contemplated embodiment discloses the addition of male and/or female snaps.

The innovative product is a joint finger ring, particularly refers to a finger ring capable of being spliced, assembled, bent and adjusted, and relates to the technical field of ornamental finger rings and watchbands. A joint finger ring is composed of a ring setting (1), inlays (2) and connection components (3), wherein the inlays (2) are arranged in the ring setting (1). The left end and the right end of the ring setting (1) are movably connected through the connection components (3). The utility model solves the problem that in the wearing process of the traditional finger ring, the size of the finger ring of a favorite style is appropriately increased to fit the finger, and consequently, it is impossible to achieve the best feeling when people wear the finger ring, and especially for the characteristics of the male finger bones, the finger ring cannot be taken off.

A buckle assembly includes a first buckle component, a second buckle component and an operating component. The first buckle component includes a locked portion. The second buckle component includes a locking portion. The locking portion engages with the locked portion along a lateral direction of the buckle assembly when the second buckle component is mated with the first buckle component along a mating direction. The operating component is partially embedded in and partially exposed out of the second buckle component. The operating component is slidable relative to the second buckle component. The operating component drives the locking portion to move away from the locked portion for disengaging the locking portion from the locked portion during a sliding movement of the operating component relative to the second buckle component. The present invention has advantage of saving labor and easy operation.

New forms of fasteners are disclosed. In some embodiments, some such fasteners include a new form of magnetic zipper or other track fastener, with two tracks of interlocking pieces moved together by magnetic force. In some embodiments, at least one of the interlocking pieces, of one of the zipper tracks, includes at least one exterior edge, interlocking with a complementary edge of another interlocking piece included in the other zipper track, when the interlocking pieces are moved into place by magnetic force. The techniques of the invention are applicable to a wide variety of applications, incorporating many different materials. For example, in some contexts, some embodiments allow rapid closing of articles, such as gym bags or sports apparel, with minimum effort, and leading to an extraordinary custom-fit to a user's preferences.

A fastener device includes a first fastener part and a second fastener part which can be mounted on one another along a closing direction and are held against one another in a closed position, and are releasable from one another in order to open the fastener device. The second fastener part has a winding element on which a tension element can be arranged and which is rotatable relative to the first fastener part in order to wind up the tension element on the winding element in a winding direction.

A clasp and connection to an opposing ring. Although applicable to any clasp system, it is especially relevant to jewelry connections in necklaces or bracelets whereby the connecting rings are quite small requiring visual acuity and manual dexterity to operate. The user pulls back the plunger within the clasp ring and sets it in a locked and open position allowing the user to gain manual dexterity for guiding the clasp towards the opposing ring. A feature in which a magnetic portion of the clasp and opposing ring allows the two rings to be guided towards each other and position them for connection and further ensure tight closure. Since visual acuity is not always possible, this magnetic guide is critical.

Systems relating to a mechanical closure or locking device configured to allow for quick connect and disconnect. The systems can be used in conjunction with compression garments. The systems can include a buckle that couples to an anchor. The buckle and anchor can include complementary features that can mechanically interface to secure the buckle and anchor together. The buckle and anchor can include complementary magnetic elements to secure the buckle and anchor together. The buckle can be manipulated to tighten or loosen an adjustable strap.

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.
