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.

An automatic carabiner gate locking system and method of operation. The system includes a frame, a gate, a gate biasing system, and a gate locking system. The gate locking system further includes a set of rotatable latching sleeves disposed over the gate. When the gate is in the closed state, the latching sleeves independently rotate between an unlocked state in which the gate is free to pivot and a locked state in which the gate may be prevented from pivoting with respect to the frame. The locked state further includes rotationally orienting the latching sleeves over the gate frame coupling region. The unlocked state further includes rotationally separating the latching sleeves to expose a locking recess over the gate recess, thereby allowing the gate to pivot. A second embodiment of the present invention relates to a method of automatically locking a carabiner gate.

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 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.

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.

Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

A carabiner includes a (a) a hook, (b) a gate including a cantilever spring and (c) a first pivot connecting the gate to the hook. A second pivot also connects the distal or free end of the cantilever spring to the hook.

Pelican hooks and related systems are disclosed. In one embodiment, the pelican hook includes a hook that defines a hook gap, a gate for the hook gap, and a gate mechanism. The gate is configured to be opened so as to open the hook gap and is configured to be closed so as to close the hook gap. The gate mechanism includes a gate actuator for opening the gate and a lock actuator for unlocking the gate. To do this, the gate mechanism is configured such that actuating the lock actuator toward the gate actuator unlocks the gate and such that actuating the gate actuator toward the lock actuator opens the gate. In this manner, the user can operate the pelican hook with a single hand and without having to let go of the pelican hook.

In the disclosed devices formed from interconnected components, each includes a yoke component, a boss component and an axle bolt. The yoke component includes: a carabiner body with a back, an opening, and a yoke formation. The yoke formation includes a U-shaped section open to the outside of the body, defining 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. A spur extends from the yoke formation. A gate on the body pivots between closed and open positions. 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 snap hook assembly includes a base assembly that has a hook at one end. A lever assembly including an actuation mechanism and an arm assembly fits through an opening defined through the base assembly. The arm assembly is positioned on one side of the base assembly and the actuation mechanism of the lever assembly is positioned on the opposite side of the base assembly. The actuation mechanism is fit within a housing so that the lever assembly may pivot with respect to the base assembly. A clasp is attached to the base assembly so that an end of the clasp is biased to contact the hook of the base assembly. When the lever assembly pivots, the arm assembly contacts and rotates the clasp to create a gap between the clasp and the hook.
