A ratchet device includes a ratchet wheel. The ratchet device further includes a first lever, the first lever rotatably interconnected with the ratchet wheel. The ratchet device further includes a second lever, the second lever rotatably interconnected with the ratchet wheel. The ratchet device further includes a first pivoting bracket, the first pivoting bracket pivotally interconnected with the first lever. The ratchet device further includes a second pivoting bracket, the second pivoting bracket pivotally interconnected with the second lever. The first pivoting bracket has a first position where the first pivoting bracket is rotated to engage the ratchet wheel and a second position where the first pivoting bracket is rotated to disengage from the ratchet wheel.

A wearable device comprises a tourniquet configured to occlude blood flow in an artery of a wearer. The tourniquet comprises at least one base plate; two anchor points connected to one of the at least one base plate and configured to anchor a first end of one of two laces; a tunnel strap comprising two lace guides connected to a first end of the tunnel strap, each configured to guide one of the two laces; and a tightening mechanism connected to one of the at least one base plate and comprising a spool configured to accept a second end of each of the two laces, and a knob configured for manually winding a portion of at least one of the two laces onto the spool. The wearable device comprises a wearable item quick release connector connected to the tourniquet, and configured to removably connect to a wearable item.

The Belt Ratcheting Device with Hidden Blade-III (HB-III) facilitates unidirectional belt fastening and fast release. The HB-III includes a turning gate rotatably installed diagonally in a channel. The turning gate has a hidden sharp blade front which operates on the lower belt surface avoiding visible scratches. The turning gate is connected to a lever by a spring. The HB-III 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. The HB-III is controlled by the lever's position. After fastening, the belt remains fastened until the HB-III is switched manually into inactive state by moving the lever. The blade's smooth side and channel's smooth surfaces minimize belt wear.

A clip adapted for use with an elongate strap for forming a tourniquet including first and second parts adapted to be connected to the strap, the first and second parts adapted to be releasably connected together to form a closed loop. The second part is adapted to movable along the strap and has an open passageway through which the strap passes. Integrally formed first and second elongate walls define at least part of the passageway and first and second grip portions for gripping the strap. The second wall is mounted for rotation about a transverse axis so as to move the grip portion of the second wall toward or away from the first grip portion.

A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.

A webbing capture area includes a first side plate and a first pin, the first pin in a first slot of the first side plate, the first pin providing rotation of the first side plate about the first slot. The webbing capture area further includes a second pin, the second pin fixed in the first side plate distal from the first pin, such that upon rotation of the first side plate, the second pin rotates on a lever arm of the first side plate. The slot has a first position and a second position and when the first pin is in the first position the first side plate in non-rotatable and when the first pin is in the second position the first side plate is rotatable.

The Belt Ratcheting Device with Hidden Blade II (HB-II) facilitates unidirectional belt fastening and fast release. The HB-II 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. The turning gate is connected to a lever by a spring. The HB-II 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. The HB-II is controlled by the lever's position. After fastening, the belt remains fastened until the HB-II is switched manually into inactive state by moving the lever. The blade's smooth side and channel's smooth surfaces minimize belt wear.

A mechanism to adjust the size of headwear is provided. Two engagement clips attach to either side of an open space on the headwear. A tooth/track connects the two clips. The clips may be adjusted to fit the size of the head.

A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.

A tourniquet includes a base plate, and a first anchor point configured to anchor a first end of a lace to the base plate. The tourniquet includes a second anchor point configured to anchor a second end of the lace to the base plate. The tourniquet includes a tunnel strap including a first lace guide connected to a first end of the tunnel strap and configured to guide the lace from the first anchor point directly to a spool, and a second lace guide connected to the first end of the tunnel strap and configured to guide the lace from the second anchor point directly to the spool. The tourniquet includes a tightening mechanism connected to the base plate and including the spool configured to accept a middle portion of the lace, and a knob configured for manually winding the middle portion of the lace onto the spool.
