Abstract: A rotary buckle comprises a female buckling element and a male buckling element. The female buckling element comprises an opening and a bucking portion, wherein a side opposite to the opening comprises a receiving chamber. The male buckle element comprises a fitting portion for fitting into the opening of the female buckling element and a latching portion for buckling position into the buckling portion of the female buckling element, wherein a side opposite to the fitting portion comprises a receiving chamber for receiving a knitted belt, and wherein a track is disposed at a side opposite to the opening of said female buckling element along which a directing element of the receiving chamber of the female buckle can be rotated.

Abstract: A fine adjustable sliding buckle is described. The fine sliding adjustable buckle has a base having two pairs of axial holes respectively for axially fitting the axles of the releasing plate and fine adjustment handle. The axles positioned on the two sides of the fine adjustment handle and the releasing plate are fitted in the axial holes on the same side of the base, and the handling portion of the fine adjustment handle has a receiving hole for receiving the releasing plate. Thus the fine adjustment handle and the releasing plate are positioned along the same direction and are positioned almost on the same plane to prevent accidental touch which would otherwise accidentally release the releasing plate from the base to loosen the adjustment belt. Thus, the fine adjustable sliding buckle of the present invention is easy to operate, safe and compact.

Abstract: A magnetic buckle. The magnetic buckle includes a male buckle having a magnetic element, and a female buckle having a magnetic element. The magnetic elements of the male and female buckles facilitate the alignment of the male buckle with the female buckle when they are positioned horizontally opposite to each other, as well as the steady insertion of the male buckle into the fit-in groove of the female buckle under the influence of the magnetic attraction. The male buckle can be prevented from slipping off vertically from the female buckle even under an external force, and this arrangement further provides a stronger resistance to the buckled state against any horizontal pulling force.

Abstract: A structure of magnetic buckle is disclosed. The structure of the magnetic buckle comprises a male buckle having a magnetic element, a female buckle having a magnetic element, wherein the magnetic elements of the male and female buckles facilitates the alignment of the male buckle with the female buckle when they are positioned horizontally opposite to each other, as well as facilitates steady insertion of the male buckle into the fit-in groove of the female buckle under the influence of the magnetic attraction. The male buckle can be prevented from slipping off vertically from the female buckle even under an external force, and this arrangement further provides a stronger resistance to the buckled state against any horizontal pulling force.

Abstract: A structure of a U-shaped lace buckle is disclosed. The U-shaped lace buckle comprises a shallow trench located at a central region. A releasing hole and a fastening hole are disposed within the central hollow region. The dimension of the releasing hole is larger than that of fastening hole. The releasing hole and the fastening hole are connected by a gradually tapering hole, wherein the dimension of the tapering hole connecting with the releasing hole is larger and the dimension of the tapering hole connecting with fastening hole is smaller. And the fastening hole comprises a plurality of protruded elements projecting from the inner surface. Further, the lace buckle comprises a through channel that passes from one end to the other end and connected through an arch-shaped groove located in between said two ends.

Abstract: The buckle is constructed to include a male buckle member and a female buckle member for joining two. The male buckle member includes a hook block at the front bottom side, and the female buckle member includes an opening adapted to receive the hook block of the male buckle member and a springy support suspending in the opening and adapted to push the hook block forwards into engagement with a part of the female buckle member when the user releases the female buckle member after the hook block has been inserted into the opening by force to push the springy support backwards.

Abstract: A structure of a lace buckle is disclosed. The lace buckle comprises a case having a pair of projected blocks at a base., an upper lid, attached to one slide of the case through and attachment part, which can be flipped through 180° to engageably coupling onto the case, wherein two oblique elastic slip lock arms extend vertically from a inner surface from a central region of the upper lid, projecting inwardly into the case. The two elastic slip lock arms will resiliently press against a lace from the top, while the two projected blocks of the case press against the lace from the bottom side, thus the lace is prevented from dislodging from the case, and remain secured in position. Thus the two ends of the lace can be secured in between two elastic slip lock arms of the upper lid and the two projected blocks of the case.

Abstract: A fastener includes a male fastening member having a springy hook plate and a retaining block and a stop block, and a female fastening member having a hook hole and a retaining hole and a recessed bearing portion. The retaining block and the stop block are forced into engagement with the retaining hole and the recessed bearing portion when hooking the springy hook in the hook hole. Turning the male fastening member outwards from the female fastening member to disengage the retaining block from the retaining hole enables the male fastening member to be separated from the female fastening member.
