A garment hanger has a body for supporting a garment and an attachment mechanism for coupling the garment hanger to a garment rod. The attachment mechanism is mounted on a top central portion of the body and has a first semi-circular ring member, a second semi-circular ring member, a bracket, and a spring means. Each semi-circular ring member has a first end and a central aperture in proximity to a second end. The bracket has a central horizontal portion and two vertical portions on opposite sides of the central horizontal portion. The first and second semi-circular ring members are mounted in a mirrored direction between the two vertical portions by a shaft passing through a central aperture in each of the two semi-circular ring members. The spring means is coupled to force the first ends of the two semi-circular ring members towards each other.

A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.

Sister hook type tool assemblies comprise mating arms having C shape lower ends grip portions that terminate in jaws. The arms preferably are held between two spaced apart housings. The arms, and housings when present, are held together by a fastener at the upper end of the assembly. The arms pivot relative to one another and to the mated housings. Each housing has a pair of forks at one end which define a U shape opening. An object received in the opening is retained when the jaw ends arms overlappingly close the fork opening, due to action of spring. The V shape lower end contour of the mated arms and inclined surfaces of the fork tips cause a rigid object to open the jaws when the tool is thrusted at the object. The jaws then close under spring force, capturing the object. Optional locking means are used to keep the jaws from unintentionally opening.

A slingbar includes a sling attachment member. The sling attachment member includes a frame including a base having a top end and a bottom end, and a hook extending from the bottom end to a hook terminus. The hook terminus and the top end of the base define an opening. The hook, base, and opening bound an interior of the attachment member. A closure element includes an outboard gate hinged to the hook terminus and an inboard gate hinged to the base. The gates have a default state in which each gate extends laterally only part way across the opening.

The invention concerns a sling gear (1) for single-arm operation by a remotely controlled gripper, in particular of a remotely controlled vehicle. The sling gear (1) has a closure (4) that can be moved from a closed position (5) into an open position (62), a sling body (2) that is closed in the closed position (5) of the closure (4) and open in the open position (82), and an push-button (18) for opening the closure (4). The push-button (18) has a gear section (68), which couples the closure (4) with the push-button (18), by transmitting movement. In order to improve the reliability in operation, also under adverse circumstances, for example in a heavily soiled environment on the seabed, the push-button (18) is, in accordance with the invention, equipped with an locking area (56), which, in the closed position (5), is to be found engaged with the closure (4), and locks the closure (4) in the closed position (5).

A buckle structure includes a hook-shaped buckle body and a movable bolt. The hook-shaped buckle body includes a question mark-shaped body and a blocking section provided at an upper end thereof, a receiving cavity is formed between the movable bolt and the question mark-shaped body. The lower end of the movable bolt is hinged at the lower end of the question mark-shaped body, the upper end of the movable bolt is elastically contacted with the upper end of the question mark-shaped body. the contact point of the movable bolt and the hook-shaped buckle body is located in the middle of the hook-shaped buckle body, so that the buckle can be easily mounted on the buckle structure as long as the buckle is sleeved on the blocking section and the buckle is moved in the direction of the receiving cavity.

A quick release mechanism for an exercise arm assembly enabling a user to switch exercise arms very quickly, the mechanism having: (a) an elongated body; (b) a curved aperture passing laterally across a distal end of the elongated body, cutting downwardly through the elongated body, and being angled towards the distal end of the elongated body; (c) a button assembly positioned near the distal end of the elongated body, moveable to either project into or project away from the aperture; and a biasing member that urges the extending portion of the button assembly into the locked position.

A carabiner having a container or empty section with the gate or solid gate. The gate may have a cap with a threaded section such that when the gate is pulled away from the body, the cap may be screwed off to reveal the empty section of the gate. The empty section may store items for the user. The cap may be received into the nose section of the carabiner when the spring forces the gate closed. A fire starting implement may be provided on the carabiner. The gate may rotate inward or outward with respect to the carabiner body.

A buckle structure includes a hook-shaped buckle body and a movable bolt. The hook-shaped buckle body includes a question mark-shaped body and a blocking section provided at an upper end thereof, a receiving cavity is formed between the movable bolt and the question mark-shaped body. The lower end of the movable bolt is hinged at the lower end of the question mark-shaped body, the upper end of the movable bolt is elastically contacted with the upper end of the question mark-shaped body. the contact point of the movable bolt and the hook-shaped buckle body is located in the middle of the hook-shaped buckle body, so that the buckle can be easily mounted on the buckle structure as long as the buckle is sleeved on the blocking section and the buckle is moved in the direction of the receiving cavity.
