Tie-down assemblies and methods of their use are provided. In one embodiment, a tie-down assembly may include a buckle, a first strap, and a second strap. The buckle may include a frame, a handle pivotably attached to the frame and configured to pivot about a first axis between an open position and a closed position, and a drum rotatably attached to the handle and configured to rotate about a second axis, wherein the second axis is spaced apart from and extends parallel to the first axis. The first strap may be attached to the frame, and the second strap may be configured to removably attach to the drum.

A magnetic clasp system, having a clasping assembly, which includes a base and a hinged locking component rotationally affixed to the base wherein the hinged locking component and the base defining a tortuous path therebetween configured to receive a strap, and wherein the base includes a magnetically responsive material. The magnetic clasp system also including a mounting assembly, the mounting assembly including a magnetically responsive material configured to draw the clasping assembly and the mounting assembly together when within a magnetic field thereof. The magnetic clasp system also including a stop configured to limit lateral translation between the clasping assembly and the mounting assembly when engaged.

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 cord lock has a housing with an interior cavity and an opening extending between the front and the back for receiving a cord, and an actuator having two legs that are configured to slide within the interior cavity of the housing. A spring is disposed between the housing and the actuator to bias the actuator in a raised position relative to the housing. There is a cam disposed in the interior cavity of the housing. The bottom of the cam is rotatably connected to the housing and the top is rotatably connected to the legs of the actuator. In a resting position, the spring presses the top of the cam against the housing such that when a cord is extended through the opening, the cam locks the cord in place between the cam and the housing. Depressing the actuator compresses the spring and rotates the cam.

A strap adjustment system has a base body having a bottom wall, two side walls and a strap retaining bar extending between the two side walls, the bottom wall having an aperture therethrough with screw threads extending around an inside surface, and a screw disc having a central protrusion and screw threads extending around the central protrusion. The central protrusion fits through the aperture in the base body by rotating the screw disc so that the threads in the screw disc mate with the threads in the aperture, such that a height of the protrusion above the bottom wall of the base body is adjustable by turning the screw disc. In situations where a high degree of friction is required, the protrusion can be positioned at a maximum height through the aperture, and in situations where a low degree of friction is desired, the protrusion can be positioned lower.

A strap buckle has a base. The base has a bottom plate and two side plates each having one end formed with a pivot hole. The base has a retaining portion spaced from the bottom plate. An opening is defined between the bottom plate and the retaining portion. A swinging member has a pivot portion pivotally connected to the pivot hole. Two opposite sides of the pivot portion have two perforations, respectively. Two transverse rods pass through the perforations and are arranged in parallel. The swinging member is pivoted relative to the base to drive the two transverse rods to rotate together. A pressing assembly has a pressing member and an elastic member. The pressing member is disposed between the two side plates of the base. A first strap is inserted between the bottom plate and the pressing member and wound around the two transverse rods.

The Belt Ratcheting Device with Hidden Blade-IV (HB-IV) facilitates unidirectional belt fastening and fast release. The HB-IV includes a turning gate rotatably installed diagonally in a channel. The turning gate has been installed with a hidden blade which controls the belt's translation by engaging the lower belt surface to avoid visible scratches. The turning gate is connected to a lever. The HB-IV has two states: active and inactive. In the active state the device works as a belt ratchet by allowing the belt to be pulled forwards while restricting any belt motion backwards. In the inactive state the belt's motion is facilitated in both directions. The HB-IV states are manually controlled by the lever. After fastening, the belt remains fastened until released. The HB-IV can be adapted to any kind of smooth leather, cloth or synthetic belts. The blade's hidden position and smooth channel's surfaces minimize belt's wear and scratches.
