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 and a second magnetic component. The first magnetic component magnetically attracts or magnetically repulses the second magnetic component during a connecting process of the male buckling component and the female buckling component along a connecting direction. 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.

Disclosed herein is a buckle including a plug member and a socket member. The plug member includes a shaft part protruding from one side of a first body, a first magnet inserted into the shaft part, a connection recess formed on the outer face of the shaft part, and at least one guide protrusion formed on the inner wall of the connection recess. The socket member includes a connection protrusion formed on one side of a second body to be inserted into the connection recess, a coupling recess formed in the middle of the connection protrusion so that the shaft part is inserted into the coupling recess, a second magnet inserted into the coupling recess, and at least one guide groove formed in the outer surface of the connection protrusion to guide the guide protrusion.

An attachment device for use with a wearable item includes a first cord end and a second cord end. The first cord end has restricting grooves and the second cord end has a buckle unit. The restricting grooves include a first groove and a second groove, and the buckle unit includes a first buckle and a second buckle. The first groove restricts the first buckle to an X-axis movement, and the second groove restricts the second buckle to movements along Y and Z axes when the first cord end is connected with the second cord end. The X, Y, and Z axes are each perpendicular to the other two. A wearable device using such an attachment device is also provided.

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.

Disclosed is a buckle including: a male buckle member; a female buckle member; locking and unlocking means locked and unlocked by a relative sliding action of the male buckle member and the female buckle member; and a releasing means for unlocking the locking and unlocking means by sliding the male buckle member and the female buckle member in a release direction.

A clasp assembly includes a pair of identical half sections configured to be coupled to one another. Each half section comprises one or more deformable features that are designed to deform during closure to create an interlocking engagement between each half section.

Apparatus and associated methods relate to a pair of magnetic mating buckles including a first buckle (205) and second buckle (210), the first buckle extending beyond the second buckle's outer perimeter forming an extended lip. In an illustrative example, the lip may be manually manipulated to separate the first buckle from the second buckle when the pair of magnetic mating buckles are in a substantially planar magnetic engagement. In some examples, one or more magnets may be fixedly coupled to the first buckle, and/or the second buckle. In some examples, the buckles may be coupled to various webbings. In an engagement example, the first buckle may be inserted through a coupling aperture (215) in the second buckle. The coupling aperture may include one or more corner notches, for example. Various pairs of magnetic mating buckles with overhanging lips may advantageously provide leverage to manually separate the buckles without tools.

A buffer device has a plate, a moveable ring, and an elastic member. The plate has an insertion hole formed through the plate, a connecting portion, and a retaining hole. The connecting portion and the retaining hole are formed on the plate and are located above the insertion hole of the plate. The moveable ring is moveably mounted out of a front side of the plate and has a slot. The slot is formed through the moveable ring. The elastic member is connected with the connecting portion of the plate and the moveable ring. A top section of the elastic member is wound on the connecting portion of the plate. A bottom section of the elastic member is wound on a top section of the moveable ring and passes through the slot of the moveable ring.

The present disclosure relates to a flap fixing buckle including: a plug member having a cross bar that transverses an intermediate portion of a loop-shaped frame, in which a coupling protruding portion in which a magnet is embedded protrudes from the cross bar; and a socket member having a coupling groove into which the coupling protruding portion is inserted and which is formed in an upper surface of the socket member, in which a magnet is embedded inside the coupling groove, and a wing portion extends at the periphery of the upper surface of the socket member, and as a result, when the flap fixing buckle is installed on a bag or the like, an aesthetic external appearance may be formed because of a simple configuration, and the flap fixing buckle may be stably and conveniently fastened.

An attachment device for use with a wearable item includes a first cord end and a second cord end. The first cord end has restricting grooves and the second cord end has a buckle unit. The restricting grooves include a first groove and a second groove, and the buckle unit includes a first buckle and a second buckle. The first groove restricts the first buckle to an X-axis movement, and the second groove restricts the second buckle to movements along Y and Z axes when the first cord end is connected with the second cord end. The X, Y, and Z axes are each perpendicular to the other two. A wearable device using such an attachment device is also provided.
