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.

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.

Base and cover members 3, 8 are pivotally connected by a pin 13. The cover member can be rotated between an opened position and a closed position. A stopper member 9 with first and second claws is mounted on the pin to rotate around the pin. The cover member has an engagement wall 7. An end 15b of a belt 15 is inserted through the cover member, the cover member is rotated from the opened position to the closed position, and the belt is pulled in a direction of drawing the belt out of the belt buckle, and thereby, the belt is locked between the second claws and a bottom wall 5 of the cover member. At the same time, the rotational moment rotating the cover member toward the closed position is generated by the engagement wall of the cover member being pressed by the belt.

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 Belt Ratchet Device (BRD) facilitates belt fastening and release. The 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. After fastening the belt remains fastened until the BRD is switched into inactive state by manually pulling a lever. Each BRD has a turning gate rotatably installed in a channel with tapered front end with sharp edge with a smooth side. A preloaded spring keeps the BRD in active state when the lever is not pulled. The BRD doesn't employ serrated surfaces, which cause accelerated belt wear. Instead, the BRD's smooth side and channel's smooth surfaces minimize belt wear. Various configurations of BRDs facilitate belt fastening of footwear. Single BRDs can be used for fastening garments and other objects.

A winding device 1 including a base 3 including a drum accommodation portion 33 that accommodates a drum 4 including upward teeth 46, the accommodation portion 33 being cylindrical and having a closed end, and a dial 5 including downward teeth (53) to rotate the drum 4. The dial 5 is moved to a locked state in which the downward teeth are engaged with the upward teeth 46 to transmit rotation of the dial 5 to the drum 4 and an unlocked state in which the downward teeth are disengaged from the upward teeth 46. The winding device 1 includes an annular gear (51) including projections and roots extending in the rotation axis direction of the dial 5 and a pawl 36 protruding from the drum accommodation portion 33. The pawl 36 is designed to engage with the annular gear. The annular gear and the pawl 36 control rotation of the dial.
