A reversible belt having an elongated strap having top and bottom surfaces, and two rows of notches on the top surface of the strap, and two rows of notches on the bottom surface of the strap. The buckle having teeth for engaging the rows of notches on the top surface of the strap, and for engaging the rows of notches on the bottom surface of the strap, when the strap is reversed.

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.

Briefly, the invention provides a one-piece buckle having a protuberance extending in a first direction and at least a second protuberance extending in a second direction opposite the first direction. Also provided is a method for fastening two portions of strap having the steps of mating a protuberance on a buckle with a first set of coaxial holes in a first and second strap portion, wherein the protuberance extends in a first direction, and mating at least one protuberance with a second set of coaxial holes in the first and second strap portions, wherein the at least one protuberance extends in a second direction opposite the first direction.

The present disclosure relates to a buckle belt assembly, including: a main body and a buckle belt. The buckle belt includes a first body and a second body sleeved on the first body. The second body includes a supporting portion, a second movable portion, and a band extending from a bottom of the supporting portion. One end of the second movable portion is connected to the supporting portion, and the other end of the second movable portion is movable relative to the supporting portion. The second movable portion includes a pair of side walls and a pair of fixing walls. The band is configured to hang hanging objects, the band is configured with a fixing hole, and the side walls are pressed to abut the fixing wall to the fixing hole or to detach the fixing wall from the fixing hole, thereby opening or closing the band.

A wristband with straps having a fixed-position keeper and a tang buckle with an elongate-hole tang is provided. The elongate hole may permit the tang to slide for a limited distance along the length of the buckle strap, thereby accommodating different wrist sizes and shapes while reducing the possibility of bridging or tang lift in the band.

Provided is a buckle locking device for the tonneau cover of pick-up trucks (II), which mainly comprises a load-bearing cross bar, a slider, a handle, a buckle block, a slide fixing block, a T-bar and an extruded aluminum frame, characterized in that: when the load-bearing cross bar and the slider is pressed by the handle of the buckle locking mechanism for buckling, it can generate a downward pulling force, which can be transmitted by the load-bearing cross bar to force the whole tonneau cover frame to generate a downward pressure, so that it can cover the truck bed tightly. Moreover, through the design of the slider mechanism, the T-bar can offer better stability and better positioning. When the buckle locking mechanism is not used, it can also be hidden inside the groove of the slider.

A belt includes an inside belt surface, a belt coating layer provided on the inside belt surface and a plurality of belt teeth in the belt coating layer. A belt adjustment system and a belt fabrication method are also disclosed.
