An adjustable buckle apparatus, comprising a buckle base (10) and an adjustment assembly (20), the adjustment assembly (20) being movably arranged on the buckle base (10); when the adjustment assembly (20) moves from a first position to a second position, the adjustment assembly (20) can be linked to a connecting strap (40) so as to change the length of the connecting strap (40) within the buckle base (10); when the length of the connecting strap (40) within the adjustable buckle apparatus increases, the connecting strap (40) located between a child safety seat and an automobile seat can be rapidly tightened, so as to constraint the child safety seat stably.

The disclosure provides a sling adjustment for increased reliability and performance compared to conventional cam and slide adjustments. The disclosed sling adjustment is a single hardware piece that includes a slider and a cam. The sling adjustment includes an antilock wedge to prevent or at least reduce binding when using the sliding feature in the tightening direction. Extruded pins are also disclosed that can reduce the cost and the number of components that are needed for reliable performance. In one example, the sling adjustment includes: (1) a slider having a pair of side walls, and (2) a cam, positioned within the pair of side walls, having an antilock wedge and a center slider bar, wherein the antilock wedge is located on a forward side of the center slider bar.

The device for adjusting and clamping a strap comprises superposed first and second rings to define a slot for the strap to pass through. The second ring presses on the first ring. The slot for the strap to pass through is bounded by an outer edge of the second ring and an inner edge) of the first ring. The two rings are movable with respect to one another so that the slot for the strap to pass through is of variable thickness. A bottom surface of the first ring opposite the top surface of the first ring has a textured area provided with several salient elements designed to form an increased friction area between the strap and the bottom surface of the first ring. The textured area is separated from the outer edge of the second ring by the slot for the strap to pass through.

The present invention is a buckle comprising: a lever having a first set of apertures and a second set of openings; a rod, wherein the rod is inserted through the first set of apertures; a pin, wherein the pin is inserted through the second set of openings; a base plate rotatably attached to the pin and positioned within the lever; a set of locking tabs in communication with the rod a bar rotatably attached to the pin; and a strap attached to the bar at a first end and releasably engaged with the base plate and the pin.

A ratcheting strap adjuster comprising a bracket, a webbing plate, and one or more captive members. The webbing plate is rotatably coupled to the bracket. Each of the one or more captive members is moveable between an engaged position and a disengaged position, wherein the one or more captive members restrict rotation of the webbing plate in one direction when the one or more captive members are in the engaged position and allow rotation of the webbing plate in the one direction and in an opposite second direction when the one or more captive members are in the disengaged position.

Disclosed is a quick release tool belt for the waist of a user, which includes a support strap, a release band with belt teeth on a first end and a binding with a release mechanism on the second end and slidably coupled to the release band. The binding has a base, a release rotationally attached to the base with a tooth lock, a tooth coupling rotationally attached to the base and engaged with the release and the release band, and a lever rotationally attached to the release and engaged with the release band with a tightening tooth. When the release is in the engaged position the tooth coupling and the lever are engaged with the release band and when the release is in the release position, the tooth coupling is operably engaged with the release and the tooth coupling and the lever are disengaged with the release band.

A ratchet bucket having a first reel member rotatably connected to a frame having a pair of arms. A lever is rotatably connected to the frame at a first end of the lever. A second reel member and a crank are rotatably connected to a second end of the lever.

A clasp having a body defining at least one passageway extending at least partially therethrough, at least a pair of engagement portions pivotally mounted across the body and adapted to engage an object located in said at least one passageway, and an actuation portion in communication with the at least a pair of engagement portions and biased in the engaged condition, wherein actuation of the actuation portion causes the at least a pair of engagement portions to disengage from the object against the biasing force.

Various embodiments of web adjusters are disclosed herein. In one embodiment, a web adjuster includes a spring-loaded cam member having a bore through which a mounting shaft or pin extends for rotatably or pivotally mounting the cam member to a frame. The cam member can extend along a central axis and include a first engagement feature positioned at a first radial distance from the central axis, and a second engagement feature positioned at a second radial distance from the central axis, larger than the first radial distance. The cam member can be rotated to engage the web to restrict movement of the web. The web adjuster can also include a handle or cover portion and a strap attached to the handle for gripping by a user to adjust the web adjuster.

The Hidden Blade Belt Ratcheting Device (HB-BRD) facilitates unidirectional belt fastening and fast release. The HB-BRD includes a turning gate rotatably installed diagonally in a channel. The turning gate has a hidden sharp blade front which operates below on the lower belt surface avoiding visible scratches. Attached at the rear is a resilient plate which acts as a spring. The HB-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. In the inactive state the ratcheting is disabled and the belt is released. Usually, the BRD is kept in active state by a preloaded resilient plate. After fastening, the belt remains fastened until the HB-BRD is switched manually into inactive state by pulling a latch. The blade's smooth side and channel's smooth surfaces minimize belt wear.
