A linkless, locking snap-hook, comprising a body member with a proximal hook, defining a proximal opening facing a first direction, and a distal hook, defining a distal opening facing a second direction. A linkless, locking snap-hook also comprising a locking mechanism which has a keeper, a biasing means, and a locking grip member. The linkless, locking snap-hook is capable of accepting a variety of attachment devices.

A safety hook includes a hook body having an opening, a pivoting portion and a latching portion. A composite link includes a fixing rod and a guiding post. The fixing rod is pivoted at the pivoting portion, and the guiding post has a positioning portion, a sliding groove and a fastening portion. The guiding post encloses the opening through the fastening portion fastened with the latching portion. A rotating kit includes a sleeve and a pin, and the sleeve sheathes the guiding post and coupled to the composite link. A resilience component is sleeved outside the fixing rod and abutted the sleeve. The composite link is restricted when the sleeve is pushed by the resilience component.

A connector for a fall protection compliance system includes a frame having an opening and a connection area configured for receiving a connection structure therein and a connection sensor assembly associated with the frame. The connection sensor assembly includes at least one permanent magnet configured for generating a magnetic field within at least a portion of the connection area, at least one magnetometer configured for detecting a presence or an absence of a disturbance in the magnetic field, and a control device having at least one processor programmed or configured to receive connection data from the at least one magnetometer, determine a connection status of the connector based on detecting the presence or the absence of the disturbance in the magnetic field, and perform at least one action based on the connection status. A method for detecting connection of a connector to a connection structure is also disclosed.

Disclosed is an underwater hook comprising a jaw latch, which, in a secured condition of the underwater hook, is releasably secured in a position closing a hook jaw. The underwater hook additionally comprises an actuation button which, for opening the jaw latch, is connected to the jaw latch in a motion-transmitting manner and occupies a closed position in the secured condition of the underwater hook. Furthermore, the underwater hook is provided with a release button blocking a movement of the actuation button away from the closed position in the secured condition of the underwater hook. In order to allow the release button to be actuated without great effort, even in the case of great forces acting on the jaw latch, the present invention provides that the release button is in engagement with the actuation button in the secured condition of the underwater hook.

A safety device comprising a support harness that includes at least one safety cable, and preferably a pair of safety cables. The end of the safety cable has a snap hook designed to releasably connect to the structure. In application, the safety harness is worn by the worker and as the worker ascends or descends the structure, the worker continuously releases and then connects one of the snap hooks to the structure such that at least one safety cable is connected to the structure at all times. The safety harness includes sensors for detecting whether the worker is ascending or descending the structure, for detecting whether at least one of the snap hooks are connected to the structure, and detecting when the worker is attempting to open the snap hook.

A carabiner includes a swivel loop and a body rotatably coupled to the swivel loop about a rotational axis. The body includes a spine having a spine axis that intersects the rotational axis at an intersection point disposed within the connection between the swivel loop and the body. The carabiner also includes a captive eye formed completely within the spine. The body and the captive eye being both rotatable relative to swivel loop.

The present invention extends to a carabiner intended for use as an adjustable anchor or a belay device. In general, implementations include a carabiner that includes a frame defining a hole and a gate. More specifically, implementations include a carabiner having a spine with an elongated slot portion having a first slot wall and a second slot wall that define a hole through the spine of the frame. Additionally, some implementations include a carabiner kit with a first carabiner having an elongated slot portion on the spine, a second carabiner, a pinching mechanism formed by linking the first and second carabiners together, and a rope that goes through the elongated slot portion, around the second carabiner, and back out the elongated slot portion of the first carabiner to enable the pinching mechanism to selectively pinch the rope for use as an adjustable anchor or a belay device.

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.
