An adjustment device includes a housing supporting a rotatable spool that is operably coupled to a tension line. The spool is configured to rotate about a first axis in a first direction to wind the tension line around the spool and is configured to rotate about the first axis in a second direction opposite the first rotational direction to unwind the at least one tension line from the spool. The device includes a lever pivotally coupled to the housing and configured to rotate about a second axis. The lever is selectively coupled to the spool to drive rotation of the spool in the first direction. The device also includes a release mechanism that is configured to selectively release the spool such that the spool is free to rotate in either the first or second direction in response to manual forces applied to the release mechanism.

The invention relates to a coupler for coupling a substantially elongated belt portion, comprising a housing, comprising a first beam, extending substantially perpendicular to the longitudinal direction of the belt portions, for guiding a belt portion, a connector, located on a distance from the first beam, at least two sidewalls, which extend between the first beam and the connector, which sidewalls are located on opposite ends of the first beam, wherein at least a part of at least one side wall is pivotable between at least two positions: a closed position wherein the pivotable sidewall portion engages the first beam to limit a belt passage between the side walls, the connector and the first beam, and an opened position wherein the pivotable sidewall portion is located on a distance of the first beam to allow passage of a belt potion between the pivotable sidewall portion and the first beam.

The present invention relates to a string adjusting device. According to the present invention, there is provided a string adjusting device, including: a base unit including a base plate, a cylindrical lower housing provided on the base plate, and stop protrusions formed to protrude from an outer surface of the lower housing; and a rotation unit including a bobbin rotatably installed inside the housing and configured such that a string is wound therearound, a rotation head connected to one end portion of the bobbin, and an engagement member formed and provided inside the rotation head to be elastically deformable and configured to be caught on the stop protrusions.

Embodiments of the invention are directed to adjustable closure devices. One embodiment has a strap, a connector attached to a strap end, a chafe mounted on the strap behind the connector, and a hinged handle on the chafe. The chafe has a two outer bars and a central bar, these bars defining strap through-paths. The strap end-region has path segments arranged, directionally from the strap's central region toward the strap end at the chafe, or, in embodiments that configure the strap as a pulley, at the connector. An adjustable length region of the strap spans between the chafe and the connector. An elevatable handle configuration allows a user to pull the chafe to which it is connected along the strap, away from connector. As the chafe moves along the strap, the strap can transition between a large circumference configuration and small circumference. Some embodiments have a strap friction-locking mechanism associated with the handle and the chafe.

A harness system includes one or more harness assemblies. Each harness assembly includes a flexible restraint formed of a coated fabric. An adjuster is provided to adjust an effective length of the flexible restraint. The adjuster includes a frame, a restraint guide, and a cam.

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.

The present invention relates generally to first aid articles and more specifically tourniquets suitable for one handed application. One embodiment of the invention is directed to a tourniquet having a base defining first and second ends. A constricting band is attached to and extends from the first end of the base. A windlass handle is engaged with the constricting band. The constricting band is threaded through a self cinching stepped buckle. A buckle connector includes a hook member that engages the stepped buckle and is partly held in place through urging against a loop of the constriction band.
