An improved quick-release connector that may be used with a pet collar. The connector is fabricated entirely of metal and operates using one magnet. The connector is easily modified to break apart under different pull forces.

There is provided a locking device for locking a wrist/leg worn device, the locking device comprising: a receiver unit having a frame structure that defines a cavity, wherein the frame structure comprises a locking edge; and a lock unit comprising a lock bar, wherein the frame structure defines an opening to the cavity configured to receive the lock bar through a sliding movement of the lock bar into the cavity such that once the lock bar is received within the cavity the lock bar engages the locking edge so as to lock the receiver unit and the lock unit together.

A fastener for accessories includes a male part and a female part. The female part is a crocodile clip, which includes a pair of jaw members operable to open/close by a spring force. The fastener for accessories includes a first attraction part and a second attraction part. The first attraction part is located at an inner space in the pair of the jaw members. The second attraction part is located at the front part of the locking part. The first attraction part is located at either one of the jaw members. In addition, a holder, into which the second attraction part of the locking part is inserted, is placed in front of the first attraction part located in the crocodile clip.

A locking device includes a sleeve, a locking assembly, and a stopper. The sleeve defines a locking cavity and stopping holes. The locking assembly includes a locking member received in the locking cavity and is rotatable relative to the sleeve to lock a hanging member in the sleeve or release the hanging member from the sleeve. The stopper and the stopping holes cooperate to position the locking member relative to the sleeve.

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 medical alert necklace is formed with a container loop wearable around a neck of a user and contains a medical dose as an ingestible for the user. The medical alert necklace includes a personalized pendant that uniquely identifies the user as having a medical condition, and includes a quick response (QR) code accessible to identify an emergency contact person for the user and/or medical information about the user. The medical alert necklace can also include an alert system that receives an alert activation from a smartphone and activates to warn of a hypoglycemic condition of the user. The medical alert necklace has a fastening system to secure the container loop around the user, such as a magnetic clasp. The fastening system includes a plunger press-fit into the container loop. The ingestible is distributable for user consumption through the plunger, and the container loop is refillable through the plunger.

A necklace keeper or clasp for securing a jewelry item and for receiving one or more charms. The clasp includes a support member constructed of a support ring that extends less than a full circle so as to define a support ring gap, and a top head piece that extends upwardly from the support ring. A sliding lock pad engages with the top head piece and is normally biased to an extended position. A guide ring is providing having a channel for receiving a support ring and extending less than a full circle so as define a guide ring gap. The sliding lock pad has a lock position in which it engages the support ring to inhibit relative rotation between the support ring and the guide ring; and has a release position in which there is relative rotation between the support ring and the guide ring so that the respective supporting ring gap and guide ring gap each align.

The present invention comprises: a wrist band part wound around a wrist of a baby; a body part which extends from the wrist band part to allow the baby to suck or chew the body part and has an inner space for receiving a hand of the baby; and a grip part, both ends of which are in contact with the body part so that the grip part extends across the inner space of the body part wherein, for storage, when the wrist band part is supported on the ground, the body part is vertically erected with respect to the ground without being tilted by self-weight thereof.

An enclosure may be provided with a housing. The housing may have an opening that separates and joins along a seam. A magnetic closure may have a pair of mating flexible magnetic members such as flexible rings or strips that run along the seam. Magnetic-field shunts may be provided in the flexible magnetic members. Multiple magnetic elements may be formed along the length of each magnetic member to form a multipole permanent magnet. Magnetic attraction may be varied along the lengths of the magnetic members and may be varied as a function of the separation between opposing magnet members. A magnetic clasp may be provided on the housing. The magnetic clasp may have attracting magnets to help close the opening in the housing. Protruding clasp portions may be formed from flexible material and may have embedded magnets configured to repel each other to facilitate use of the clasp.
