An embodiment personal item management apparatus includes a wearable band having a fixed circumference that defines a first outer diameter; and a clasp coupled to the wearable band, the clasp having a second outer diameter that is less than the first outer diameter and being adapted to couple a personal item to the wearable band. In an exemplary embodiment, the ratio of the second outer diameter to the first outer diameter is about 0.4.

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.

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.

An elastic press-lock structure has a ring-shaped member and a connection assembly. The ring-shaped member is defined an elongated hole. The connection assembly is passed through the elongated hole of the ring-shaped member and detachably connected with the ring-shaped member. The connection assembly is pressed with a pressing force to deflect toward a first direction with an axle which is a predetermined position of the elongated hole so that the connection assembly is limited by the ring-shaped member which is deformed and the then the connection assembly is reset toward a second direction opposite to the first direction by a restoring force generated by the connection assembly while the pressing force is released.

A utility device includes a base tapered at an edge and a clip. The clip includes a hook, and when in a closed position, the hook fits into a recess of the clip and is unable to receive an object. However, in an opened position, the hook is pivoted away from the clip and is able to receive an object. An abutment prevents the hook from opening further than the opened position. The clip further includes a channel with overhangs and retainers that prevent an attached corresponding rotatable attachment piece from detaching from the channel. The corresponding rotatable attachment piece may attach to the channel and rotate within the channel. However, a first and second set of stoppers limit the rotation of the corresponding rotatable attachment piece within the channel. Further, the utility device may include a slot offset from the base to receive a corresponding fixed attachment piece.

A thumb tab actuator for a firearm sling snap-hook is provided. The thumb tab actuator includes a body having a surface that engages a lever of a snap-hook that pivots in a first plane. The actuator body is adapted to be removably mounted to the lever, and the body includes a tab extending outwardly in a second plane transverse to the first plane when the body is mounted to the lever, such that the lever pivots in response to a force exerted on the tab. A user may couple the thumb tab to the snap-hook via a screw or other fastener. In some embodiments, the thumb tab includes a second tab for an ambidextrous configuration.

A snap hook includes a body, a gate, a connection link, and a coupling. The body has a central portion positioned between an upper portion and a lower portion. The gate is pivotally coupled proximate the central portion. The gate and the body selectively form a closed configuration that defines a hook connection passage and an open configuration that provides access to the hook connection passage. The connection link has an upper end pivotally coupled proximate the central portion of the body and a lower end including a body connection aperture. The coupling interconnects the lower end and the lower portion. The coupling is configured to break when a select amount of force is applied to the lower end and release the lower end from the lower portion to redirect the select amount of force from the lower portion to the central portion of the body.

A snap hook that includes a body, a gate, a connection link and a breakable fastener is provided. A central portion of the body is positioned between an upper portion and a lower portion. The gate is pivotally coupled proximate the central portion of the body. The gate and the body selectively forming a closed configuration that defines a hook connection passage and an open configuration that provides access to the hook connection passage. An upper end of the connection link is pivotally coupled proximate the central portion of the body. A lower end of the connection link includes a body connection aperture. The breakable fastener couples the lower end of the connection link proximate the lower portion of the body. The breakable fastener is configured to break when a select amount of force is applied to the lower end of the connection link to transfer the force from the lower portion of the body to the central portion of the body.

A link such as a karabiner has a body portion and a gate portion which is mounted to the body portion about a pivot. The gate defines a free end which is arranged to inter-engage with a nose of the body portion to define a closed ring for receiving a rope passing therethrough and including a first sleeve which, when the ring is closed, is moveable between a first position where the gate is free to rotate about the pivot in at least one direction, and a second position where the sleeve at least partly encloses the free end of the gate and the nose and substantially prevents rotation of the gate about the pivot. The link further includes a second sleeve which is internally threaded and which is mounted on an externally threaded portion of the gate for movement towards and away from the free end of the gate and which may be rotated towards the first sleeve when the first sleeve is in the second position, to prevent movement of the sleeve into first position in which the gate is free to rotate. A dual sleeve maillon, of similar design but omitting the pivoting gate having two sleeves is also described.
