An adjustable buckle secures a head strap to a head-mounted display and is operable between a first stable mode and a second stable mode in which the adjustable buckle transitions between a shorter and a longer effective length to adjust the fit of the head strap according to a wearer's preference. The adjustable buckle comprises a first plate, a second plate, a third plate, and a fourth plate. The first plate secures to the head strap, and the second plate secures to the head-mounted display. The third and fourth plates are bendably connected between the first and second plates via flexible hinges. The second plate is slidably movable along guide member(s) extending between the first and second plates. Rotation of the fourth plate about its flexible hinges causes corresponding translation of the second plate along the guide member(s), placing the adjustable buckle in the first or second stable mode.

Duty belt core constituting a rigid backbone of a duty belt, comprising a left hand side piece firmly attached to a left hand half of a front belt buckle, a right hand side piece firmly attached to the right hand half of the front belt buckle. Each of the left hand and right hand side pieces is connected to a common back piece via side-symmetrical length adjustment patterns and safety stops preventing accidental disengagement of the side pieces from the common back piece. A belt buckle provided with extensions, as well as use hereof is also disclosed.

A mechanical-magnetic locking device includes a first connecting component, a second connecting component and a magnet-armature structure. The first connecting component is provided with a locking element with a gap; the second connecting component is provided with a locking member matched with the locking element with the gap. A magnet is provided in one connecting component and an armature is provided in the other connecting component. The locking element with the gap is coupled with the magnet and the armature is coupled with the locking member. When opening the locking device, the magnet and the armature are relatively moved to each other, and the magnetic attracting area is substantially unchanged or increased, allowing the locking element with the gap and the locking member to move from the engaged position to the non-engaged position. The locking device has a self-locking function, locking with adjustable positions, smooth connection, good good haptic, not easy to open after connection and is stable and reliable.

A shoulder strap device and method provides a movable and/or swiveling attachment arrangement which spreads the load to the wearer's specific shape. Embodiments of the device include a set of strap ring components, each strap ring component having a substantially linearly extending base portion and a substantially curvilinearly extending retention portion, first and second connector items or straps secured to respective subsets of the strap ring components, and a body garment secured to the strap ring components.

Provided is a buckle device including: an anchor member that is attached to a vehicle; a buckle main body to which a tongue attached to a webbing for occupant restraint becomes fastened; a coupling member that is flexible and couples the buckle main body and the anchor member to each other; a support member that is formed in a tubular shape and in which the anchor member, the buckle main body, and the coupling member are housed; and contact portions that are provided on the support member and with which the support member supports the buckle main body with respect to the anchor member in a state in which the contact portions contact, in the thickness direction of the anchor member, one side portion and another side portion of the anchor member.

A buckle structure contains a male buckle, two fastening arms, and a resilient sheet. The male buckle includes a first opening, a second opening opposite to the first opening, an external fence, and an accommodation cavity, wherein the external fence has two first orifices. Each of the two fastening arms includes a through hole, an engagement portion, a first abutting face, a second abutting face, and a column rotatably connected with the first orifice and the through hole so that the first abutting face and the second abutting face are located in the accommodation cavity of the male buckle, and the engagement portion of each fastening arm extends out of the first opening of the male buckle. The resilient sheet is formed in a U shape and includes a convex arc face and two contacting segments arranged on two ends of the resilient sheet respectively.

A buckle-type closing device (30), placed between two parts to be connected to one another, comprises a first component (31) and a second component (32) that are associable with one another in a releasable manner in which said first component (31) of said closing device (30) comprises a chamber (33) in which a magnet (34) is housed and a support element (35), and in which said second component (32) comprises a ferromagnetic locking element (40) that is adapted to interact, in operation, with said magnet (34), said locking element (40) being movable between a first released position and a second locking position in which it (40) is attracted by said magnet (34) against said support element (35), said locking element (40) consisting of a lever that is rotatable with respect to a pin (43), said lever having a folded end (46) forming a coupling element associable with said support element (35), said second component (32) comprising a mechanical element adapted to act on said locking element (40) to overcome the force of magnetic attraction of the magnet (34) and return the locking element (40) to the released position of said first component (31) with respect to said second component (32) of said closing device (30). Said mechanical element comprises a pair of release components (42) that are elastically opposite one another specularly with respect to the longitudinal centreline of said closing device (30), each release component comprising a respective inclined plane (44) adapted to release said locking element (40) wedging itself between said rotatable lever and a fixed part, and removing said rotatable lever with respect to said magnet (34) and thus releasing said locking element (40) from said support element (35).

Provided is a buckle including a plug and a socket. The plug includes a pair of leg portions, each of which is provided with an engaging portion, and outer and inner leg pieces extending while opposing each other. In the vicinity of a distal end portion of the leg portion, the outer and inner leg pieces are connected to each other by a distal end connection portion. On a base end portion of the leg portion, the outer and inner leg pieces are connected to each other by an arm portion. Opposing arm distal end portions of the arm portions are formed to define a slit having a predetermined space between the leg portions. The opposing arm distal end portions are connected to guide portions extending in a protruding direction of the leg portions. The pair of leg portions is provided to be swingable across the slit.

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 link or slide for a garment strap includes mutually parallel longitudinal bars and a pair of opposing transverse bars each forming a juncture with ends of the longitudinal bars. The transverse bars curve forward from the junctures away from the rear of the longitudinal bars, reducing potential discomfort to an active wearer. In embodiments, the link is formed of resilient material and the link thickness tapers to a minimum at the junctures, forming flexible zones which provide added comfort. In additional embodiments, the longitudinal bars have angled edges adjoining slots through which the garment strap passes. The angled edges resist undesirable motion of the strap, especially while the wearer is exercising.
