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.

A ratchet housing assembly for encasing the ratchet strap device from water damage includes a capsule having a cylindrical shape and made of a plastic material. The capsule has a perimeter wall enclosing an interior that defines a space for encasing a ratchet assembly. Furthermore, the perimeter wall has a first edge and a second edge. A side wall is positioned on the first edge of the perimeter wall and a cap is attachable and removable from the second edge of the capsule. The cap is the plastic material and has a hole for inserting a shaft of the ratchet assembly within. A flap assembly is nested within the perimeter wall of the capsule and comprises a pair of flaps. An opening is positioned between each of the flaps and the opening defines an access to the interior of the capsule.

A tourniquet for application to a patient's limb in an emergency situation, and a method for its application. The tourniquet includes a tension-sensing mechanism used to establish a baseline tension in a loop around an injured limb, and a tension-increasing mechanism to reduce the circumference of the loop and tighten the tourniquet as required beyond the baseline tension. The tension-sensing mechanism may be incorporated in a buckle in which when sufficient tension is developed in the loop a pin protrudes to engage and maintain tension in a strap member which is part of the loop. A latch may be incorporated in the buckle to keep it in a condition in which the pin protrudes to engage the strap and maintain the baseline tension. A release tab operable to release the latch is located where it is protected against inadvertent operation.

An apparatus for ratcheting multiple restraint webs includes first and second locking web retractors each coupled to one end of a different restraint web. When locked, the web retractors each prevent web movement in a web pay-out direction relative thereto. The apparatus further includes first and second ratcheting devices each coupled to a corresponding one of the web retractors, and each is movable in a direction that moves the corresponding web in a web take-up direction relative to its web retractor when the web retractors are locked. The apparatus further includes an actuator movable between two positions and coupled to each of the ratcheting devices. The ratcheting devices are each responsive to a moving force applied thereto by the actuator as the actuator moves between its two positions to move in the direction that moves its corresponding web in the web take-up direction.

A tool-operated 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, and to rotate in a second direction opposite the first direction to unwind the tension line. The device includes a socket pivotally coupled to the housing and configured to rotate about a second axis. The socket is selectively coupled to the spool to drive rotation of the spool in the first direction. The socket is configured to removably connect and disconnect to a tool configured to rotate the socket about the second axis. The device 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 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.

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 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.

A buckle configured to hold a wrapped weightlifting belt and provide fine adjustments to the snugness or tightness of the weightlifting belt is disclosed. The buckle may include an adjustable element, which allows the buckle to pull-in or ease the two ends of the weightlifting belt. The adjustable element may be a worm screw that can be rotated by a user to move a car of the buckle relative to the body of the buckle. The car may have legs that hold onto one end of the weightlifting belt via holes in the weightlifting belt, while the other end of the weightlifting belt is fixed to a fastener plate of the buckle. The buckle may include a wedge and lever design to latch the buckle closed. Additionally, the buckle's rugged design allows for the manufacture thereof with polymeric materials using low-cost manufacturing techniques, like injections molding.

A strap that includes a buckle, a lever affixed to the buckle, a lever tooth disposed on the lever, a band affixed to the buckle, and a plurality of tooth catch holes disposed on the band, where the plurality of tooth catch holes are adapted to interlock with the lever tooth.
