An insulating carabiner hook is characterized in that a free end of an insulating gate includes a first insulating section and a second insulating section. A color of the second insulating section is different from a color of the first insulating section. A restricting sleeve could move along an axial direction of the insulating gate. When the free end abuts against an abutting portion of an insulating body, and the restricting sleeve completely covers the second insulating section, the restricting sleeve is located at a safe position and cannot freely pivot. When at least a part of the second insulating section is exposed via the restricting sleeve, the restricting sleeve is located at a warning position. An insulating gate and a manufacturing method thereof are also disclosed.

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.

A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least two pairs of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

A hook lock and method are provided for retaining a workpiece on a hook of an industrial rack. The hook includes a shank having a cross-sectional width, defining a bend for receiving the workpiece thereon, and terminating at a terminal end. The hook lock includes a block having a passageway extending along an axis between first and second outer surfaces of the block. The passageway has a cross-sectional width less than or equal to the cross-sectional width of the shank. In operation, the hook is inserted through the workpiece, and thereafter, through the passageway in the block such that the block is frictionally retained on the shank of the hook. The block prevents the workpiece from being disengaged from the hook as the workpiece is transported along a line.

A divider (10) for a carabiner (12) in a fall arrest system (14), the carabiner (12) having a frame (32); and an openable gate (34) configured to be moved between an open position and a closed position, the divider (10) comprising a body (50) having: (i) a central body portion (52); and (ii) a plurality of connection portions (54) extending from the central body portion (52) and configured to attach the divider (10) to at least a portion of the frame (32) of the carabiner (10), wherein the plurality of connection portions (54) are spaced and divide the carabiner (12) into a plurality of areas (56) for connection of at least one component (18, 20) of the harness arrangement (16) and at least one fall arrest device (22).

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 self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least two pairs of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

Devices formed from interconnected components. Each assembled device comprises a yoke component, a boss component and an axle bolt. The yoke component comprising: a. carabiner body that includes a back, an opening, and a yoke formation. The yoke formation is constituted by a U-shaped section that is open to the outside of the body, and which defines a space between two legs, the legs having bearing surfaces through each of which a respective axle bore is formed. The back extends from the yoke formation to an end at a first limit of the opening. A spur extends from the yoke formation to an end at a second limit of the opening. A gate on the body can pivot between a closed position, in which it closes the opening, and an open position in which an object can be passed through the opening into a space within the body. The boss component has flat, parallel external bearing surfaces, an axle bore extending through the boss component, the axle bore opening at each bearing surface. The axle bolt passes through the axle bores in the yoke and boss component.

A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.

A Irreversibly Locking Clip. The clip has a hinged latch that pivots from an open position to a closed position, similar to a conventional caribiner. The clip provides the structural strength and durability of a caribiner or shackle. The clip includes one or more spring-loaded pins that will irreversibly lock the latch in a closed position by extending into a corresponding socket when the latch is closed. Additionally, the clip incorporates a retaining tip at the tip end of the latch that engages a tip retaining socket when the latch is closed in order to provide additional reinforcement between the latch and the body of the clip.
