According to one aspect of the present invention, a buckle for a clothing belt includes a first rotating body supported by the first shaft so as to be rotatable, an open end portion of the first rotating body being capable of being disposed between a bar and a back plate of a base body by making a first shaft slid; and a second rotating body supported by a second shaft so as to be rotatable with the second shaft as a fulcrum, formed so as to have a second convex portion, and capable of hindering a movement of the first rotating body in a direction opposite to the bar side with the second convex portion in a state where the second convex portion is rotated so as to be pushed in toward the opening portion of the back plate.

A belt buckle structure includes a buckle body and a plate-based controller. The buckle body is provided with a coupling section and a connection section at two ends thereof. The coupling section is formed with a pivoting notch in a top side and a recess in a bottom side. A pin hole is formed in each of two sides of the buckle body. The plate-based controller includes a coupling axle having a pawl. The coupling axle is arranged in the coupling section. A fixing member has a protruding section fit into the recess. A pin is received through the pint hole to penetrate through the recess and extend into a positioning hole of the fixing member. A primary constraint frame has two side portions collaborating with the pin to attach to two sides of the buckle body.

A closure device for releasably connecting two parts with each other includes a first closure member having a rigid first locking protrusion and a second closure member which is attachable to the first closure member and in a closed position is held on the first closure member. The second closure member has a rigid second locking protrusion. The second locking protrusion can be brought into engagement with the first locking protrusion in an engagement direction and in the closed position engages the first locking protrusion in a positive locking manner. The first closure member includes a first magnetic member and the second closure member includes a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device.

A combination strap connector and adjuster for connecting straps of a safety harness and for adjusting at least one of the straps comprises a base including a first connector portion, a second connector portion, and a third connector portion. The first connector portion is configured and arranged to directly connect to a first strap extending in a first direction away from the base. The second connector portion is configured and arranged to directly connect to a second strap extending in a second direction away from the base. The third connector portion is configured and arranged to directly connect to a third strap extending in a third direction away from the base. The first, second, and third directions are different directions relative to the base. An adjuster is operatively connected to at least one of the connector portions.

The Belt Ratcheting Device (BRD) facilitates unidirectional belt fastening and fast release. The BRD has a turning gate rotatably installed diagonally in a channel. The turning gate has a tapered front end with sharp edge with a smooth side. A preloaded spring keeps the BRD in active state when the release lever is not pulled. The BRD has two states: active and inactive. In the active state the device works as a belt ratchet i.e. allowing the belt to be pulled forwards but restricting any belt motion backwards. After fastening, the belt remains fastened until the BRD is switched into inactive state by manually pulling the lever. The BRD doesn't employ serrated surfaces, which cause accelerated belt wear. Instead, the BRD's smooth side and channel's smooth surfaces minimize belt wear. BRDs facilitate garment belt fastening or belt fastening of footwear.

A buckle used to fasten opposing ends of an object encircling strap around a bundle. The buckle includes a base and a lever tensioner. The base has a bottom and two opposing sides extending from the bottom. Each side includes a first end and a second end. The sides at the first end of the base have pivot holes. The lever tensioner is pivotally connected to the base. The lever tensioner includes a first end and a second end. The first end of the lever tensioner includes pivot hinge tabs. The pivot hinge tabs are positioned in the pivot holes of the base to pivotally secure the lever tensioner to the base.
