Abstract: The present invention concerns an accessory device for face coverings, surgical masks and filtering facepieces, which performs the dual function of a diffuser, in particular of fragrances and scents to neutralise unpleasant odours that may form in the area in front of the user’s mouth, and also as a sign of recognition of its own mask by the user.

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 buckle device capable of displaying a locked state includes a main body unit, a latch unit, a fastening unit, an electromagnetic unit, and a control unit. The main body unit includes a main body and the latch unit includes a detachable tongue element. The fastening unit includes a bolt body interfering with the tongue element. The electromagnetic unit includes an electromagnetic module and an electromagnetic rod. The electromagnetic module controls the electromagnetic rod to interfere with the bolt body. The control unit includes a control module, a display module and a magnetic rod detection module for detecting the position of the electromagnetic rod. The control unit receives detection information of the magnetic bolt detection module and controls the display module to display a current state according to the position of the at least one electromagnetic rod.

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.

The present invention has disclosed a magnetically-attracted buckle and a wearable device, which pertain to the technical field of strip-connecting structures. The present invention enables the first buckle and the second buckle to connect with each other by one hand, and the second magnetically-attracted member inserted into the hollow hampers the second buckle from being pulled out of the first buckle, avoiding the second buckle from easily separating from the first buckle.

An assembly includes an elongated strap with a length extending between a first end and a second end, a first magnetic element proximate the first end of the strap, a second magnetic element proximate the second end of the strap, and a fastener attached to the first end of the strap. In some examples, at least one of the first and second magnetic elements is a rare earth magnet.

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

A magnetic buckle assembly includes first buckle component, a second buckle component for mating with the first buckle component, a switch movably disposed on the second buckle component, an operating component slidably disposed on the second buckle component and for driving the switch to move. The first magnetic component, a first magnetic component disposed on the first buckle component, a second magnetic component disposed on the switch and for magnetically attracting or repelling the first magnetic component, and a latch movably disposed on the second buckle component and for engaging with the first buckle component. The latch moves along with sliding movement of the operating component. The operating component drives the switch to move to change a direction of a magnetic force of the second magnetic component acting on the first magnetic component when the operating component is operated to slide to disengage the latch from the first buckle component.

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 coupling device for releasably coupling two parts with one another includes first and second coupling members having magnets for holding the members with a magnetic holding force to self-center the members in an intermediate position. The coupling members are slidable to a locked condition in which mutual interlock portions engage and slidable to an unlocked position in which mutual unlock portions engage. The coupling members are uncoupled by sliding the members along a first unlocking path to the unlocked position and further moving the members along a directionally different separation path.
