A cord reel cable including a cable with tinsel sheath surrounding power and data conductors, wherein the tinsel sheath is comprised of no more than 40 tinsel or tinsel strands, and the cable is wound and unwound around a spool while maintaining continuous electrical contact to a power source through a slip ring mechanism or the like, wherein the tinsel sheath provides a durable EMI shielding to the cable.

A cable reel of the present disclosure can include two flanges and a central drum being independently rotatable from one another. The drum, which can be configured to receive a cable, can be mounted on an axle. The two flanges can be rotationally mounted on the axle at opposing distal ends of the axle. Bearings in the flanges can allow for a full rotation of the flanges about the axle.

A fish tape tool includes a housing including a base and a cover. The housing defines a chamber between the base and the cover. The base defines an exit opening and a channel extending from the chamber to the exit opening. The fish tape tool also includes a drum configured to be inserted into the chamber of the housing, the drum containing a fish tape. The drum is configured to be manually rotatable relative to the housing to dispense or retract the fish tape from the housing via the channel and the exit opening. The cover defines a central aperture that is aligned with a central bore of the drum.

A reel assembly (10) having a spool (20) comprising a drum core (22) and side disc flanges (24) attached to the drum core (22) for retaining a wound hose (26) on the spool (20), and a release mechanism (120) operatively engaging the spool (20) via a drive shaft (110). The release mechanism (120) has a pair of rotatable hubs (132, 134) arranged in axial alignment and having a clamping spring (136) fitted around the rotatable hubs (132, 134) and arranged to clamp the hubs (132, 134) together in fixed rotational relation, wherein the clamping spring (136) opens to releases the rotatable hubs (132, 134) when the spool (20) is rotated in a payout direction so that the rotatable hubs (132, 134) disengage and the spool (20) can freewheel.

A fish tape tool includes a housing and a chamber defined in the housing. A drum is configured to be inserted into the chamber of the housing. The drum contains a fish tape. The drum is rotatable relative to the housing to dispense or retract the fish tape from the housing. The drum is one of a plurality of drums that are insertable into and removable from the chamber of the housing. Each drum contains a different type of fish tape.

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 cord reel apparatus includes a circular plate configured to rotate in response to pulling out or rewinding of a cord, a guide groove on the circular plate, a sensor member having a first protrusion which is slidable in the guide groove, a top plate facing the circular plate with the sensor member sandwiched therebetween, a second protrusion provided on the sensor member and projecting in a direction toward the circular plate, and a first pressing portion provided on the sensor member and disposed in a direction toward the top plate. When the first protrusion is closest to a bottom surface of the guide groove, the second protrusion is not in contact with the circular plate. When the first protrusion rides on a wall surface of the guide groove, the first pressing portion is in contact with the top plate, so that the second protrusion contacts the circular plate.

A retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

When the first protrusion rides on a wall surface of the guide groove, the first pressing portion is in contact with the top plate, so that the second protrusion contacts the circular plate.

A strap feeding device includes first driving and driven rollers, second driving and driven rollers, an actuating unit, and a detecting unit. The actuating unit can move the second driving roller between a released position, where the second driven roller is spaced apart from the second driving roller, and a contact, where the second driven roller contacts the second driving roller and is co-rotatable with the second driving roller to clamp and move a strap. The control device controls rotation of the first and second driving rollers to feed and return the strap, detects rotation of the first driven roller, and controls the actuating unit to move the second driven roller to the contact and released positions.
