A buckle according to the present invention has two opposing ends that are removably attached to each other using a locking system. On one end of the buckle, the locking system includes two opposing locking pins coupled to a spring that is fully enclosed and protected from external elements. On the other end, corresponding rivets or pin casings with plungers are operable to receive the locking pins and lock the two ends together or push the pins out of the casings to release the buckle. The buckle may also include a plug that is removably attached to the adjustable loop end and allows the central bar of the adjustable loop end to be removed without deforming the central bar. Alternatively, each end of the buckle may include self-aligning tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.

Two-stage clasp mechanisms, and related systems and methods, are disclosed herein. In some embodiments, the clasp mechanism includes a first housing portion, a second housing portion configured to connect to the first housing portion, and a locking mechanism configured to secure the first and second housing portions together. The locking mechanism can include a first striker carried by the second housing portion, a second striker movably carried by the first housing portion, and a blocking component movably carried by the second housing portion. The second striker is moveable along a first direction between an engaged position and a disengaged position with the first striker. The blocking component is movable along a second direction at an angle with respect to the first direction between a first position that prevents the first striker from moving and a second position that allows the second striker to move.

A plug for a buckle includes an attachment portion configured to be attached to the predetermined members; a pair of leg portions protruding in the same direction away from the attachment portion; extending portions extending in a direction from tip end portions of the pair of leg portions toward base end portions of the leg portions; a coupling piece coupling the base end portions of the pair of leg portions; a first restricting portion that is located at an intermediate portion of the coupling piece and faces extending ends of the extending portions; and second restricting portions that protrude from two sides in a longitudinal direction of the coupling piece in a manner of sandwiching the first restricting portion, extend in a protruding direction of the leg portions, and face inner side surfaces of the leg portions.

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.

A buckle assembly with a disengagement prevention device and a method for using the same is disclosed. The buckle assembly has a first buckle member having a first strap holding structure configured to adjustably affix the first buckle member to a first strap segment. A second buckle member is configured to couple with the first buckle member, the second buckle member having a second strap holding structure configured to affix the second buckle member to a second strap segment. A disengagement prevention device is configured for engagement with the first and second buckle members to maintain the first and second buckle members in a coupled state under conditions where the first and second buckle members are not properly engaged or the engagement between the first and second buckle members is accidentally released.

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.

A side-release buckle includes a plug and a socket for inserting and engaging the plug, and when a cross section of the engaging surface is observed from an in-plane direction of the first mold mating surface defined by a first parting line of the plug, and from an direction perpendicular to an insertion direction, a surface to be engaged is located on the opposite side to a first belt winding portion with respect to the first mold mating surface, and has a first engaging surface forming an angle A.sub.1 with the first mold mating surface of 87° or more and 90° or less.

The invention discloses a light up buckle for use with a dog collar. This buckle design comprises a Plastic Computer Board (PCB) which incorporates LED's, a mini-USB port, a switch and a rechargeable battery. The lithium-ion battery is housed within the buckle assembly and is protected from water by means of rubber seals when the buckle is in the closed or locked position. The main components are molded from translucent plastic, to allow the LED's to illuminate the assembly when switched on. There are multiple settings for the LED's to allow for a steady illumination or various flashing/pulsing settings. The buckle is intended for illumination at night to aid the visibility of an owner's canine that wears the buckle on the collar. The buckle can be fitted onto a collar strap or body harness and so has multiple uses and applications. The buckle design is rounded and has smooth edges to ensure no discomfort is experienced by the canine. There is a trigger switch located on the underside of the buckle which is operated by pressing a rubber button that protrudes from the plastic casing. The entire assembly is water-resistant, by means of two rubber components that interlock when the buckle is closed. The pressure between these two rubber plugs ensures water cannot get access to the electronics and battery.

A locking buckle comprising a first buckle member and a second buckle member. The first buckle member may comprise a first strap-receiving slot for receiving a first loop end of a strap, the first strap-receiving slot is defined in part by a strap-retaining bar and a body of the first buckle member and a strap-locking bar pivotably attached to the body of the first buckle member, the strap-locking bar pivotable between an unlocked configuration in which a strap may freely pass through the first strap-receiving slot and a locked configuration in which a strap passing through strap-receiving slot is prevented from passing freely through the first strap-receiving slot. The second buckle member is connectable to the first buckle member. The second buckle member comprises a second strap-receiving slot for receiving a second loop end of the strap.

A pet buckle includes a buckle body and a snap-fit member that can be inserted and fastened together, and a buckle cavity is disposed in the buckle body, the clip component is provided with an insertion section matched with the fastening cavity and is used for the belt adjusting portion of the webbing adjustment is characterized in that: a stretched extending piece is disposed on a bottom surface of the buckle body fastening cavity, and the extending piece extends to the card when the button body and the engaging member are fastened to each other. The strap adjustment portion of the connector presses the webbing of the strap adjustment portion.
