A dual retractable badge and key holder apparatus for conveniently securing keys and a badge includes a spool housing having an outer wall, an inner wall, and a sidewall. A median wall is coupled to the sidewall and lies parallel with the outer wall and the inner wall to define an outer cavity and an inner cavity. An axle is coupled to the spool housing. A pair of retractors comprises an outer retractor and an inner retractor coupled to the axle within the outer cavity and the inner cavity, respectively. Each retractor comprises a spool having a spring and a cord wound around the spool. A key ring is coupled to the inner retractor and is configured to secure a plurality of keys. A badge clip is coupled to the outer retractor and configured to secure a badge. A clamp is coupled to the axle adjacent the inner wall.

A fall arrest device includes a bracket, a rotating member rotatably mounted to the bracket, a safety belt wound around the rotating member, a brake wheel connected to the rotating member, a brake block pivotally connected to the brake wheel, and a restoring spring fitting around the second segment and having one end thereof terminating in a ring that has an inner diameter smaller than an outer diameter of the first segment. Another end of the restoring spring is connected to the brake block. The brake wheel has a fixed rod having a first segment and a second segment. An outer diameter of the first segment is greater than an outer diameter of the second segment. The restoring spring urges the brake block to be located in a restoring position. Thus, the restoring spring could be prevented from falling out of the fixing rod.

A balancer for tools includes a rotary drum for winding and unwinding a cable, which is adapted with a free end thereof to support a tool. The balancer also includes a spring, wound around the main rotation axis of the drum, which is adapted to develop an elastic reaction contrasting the unwinding of the cable.

A Venetian blind includes two string reels, two spring reels, a leaf spring and a wheel set. The string reels are engaged with each other. The spring reels engaged with each other. The leaf spring includes two sections respectively wound on the spring reels so that one of the sections of the leaf spring gets longer and the remaining one of the sections of the leaf spring gets shorter when the spring reels are rotated. The wheel set connects one of the string reels to one of the spring reels. None of the spring reels is engaged with any of the string reels without the wheel set.

An automatic winding device includes a lower casing having a shaft, a bobbin rotatably disposed on the shaft, a wire wound around the bobbin, a spring having a first end secured to the shaft and a second end secured to the bobbin to provide a rotational force to the bobbin, a track cover coupled to the bobbin and having tracks formed thereon, a pin positioned between the bobbin and the track cover to control rotation of the bobbin, and a pin guide spring configured to press the pin toward the track cover. The track cover includes an inner track having a radius of curvature increased and decreased along the circumferential direction, an outer track spaced apart from the inner track, a connection track configured to connect the inner and outer tracks, and a stop track configured to connect the inner and outer tracks and to stop the pin.

This invention is embodied in a body mount and retractable lanyard that enables its user to pull and retract a device perpendicularly from the face of a spool connected to a user. In this way, the body mount enable its user to access hands-free portable power, video and data transfer for public safety personnel and others operating in extreme and challenging environmental conditions.
