Provided is a reel for a conductor of an electric fence. The reel includes a bobbin, a frame for supporting the bobbin, and a connector. The connector can be two jaws and can have passages to connect the reel to a support such as a conductor of an existing fence or a tube of a vehicle. One of the jaws can be wide for stability. The connector can have an electrical conductor for connecting to the support and electrifying the conductor. The connector can also be operated by a trigger and can have a locking mechanism. The frame can be a one-piece frame made of plastics material. The reel can have a spreader and a hot-up bar. The reel can have a crank that can be disengaged from the bobbin and a brake that is applied when the crank is disengaged.

An apparatus includes a housing, a rotatable spool disposed within the housing, a belt at least partially wound onto the spool, a motorized retraction mechanism disposed within the housing, coupled to the spool, and configured cause rotation of the spool in a first direction for winding the belt onto the spool, and a tensioning mechanism disposed within the housing, coupled to the spool, and configured to prevent over-rotation of the spool in a second direction opposite the first direction while the belt is being dispensed from the spool.

A torsion spring used in a flexible display device includes a spring body having a first connection end configured to connect a reel of the flexible display device, and a second connection end configured to fix the torsion spring. An axial sectional area of the spring body near the first connection end is greater than an axial sectional area of the spring body away from the first connection end. When the reel rotates, the torsion force generated during the initial rotation of the reel is relatively large, and with the increase of the rotation turn number of the reel, the increase of the torsion force is relatively small.

A device tethering system is provided for securing a device to a source location as may be assisted by a tether. The device tethering system may include a retraction component, tether, pouch, belt, device mounting component, device aspect of the device mounting component, and/or tether aspect of the device mounting component. A method for securing a device to a source location using the device tethering system is also provided.

According to an example aspect of the present invention, there is provided a spring loaded retractable device comprising a frame, a movable part hinged to a first pin and comprising an opening radially aligned to the first pin, wherein a strap is movable through the opening, and wherein the movable part is configured to move from a first position into a second position by rotating around an axis of rotation due to friction between the movable part and the moving strap.

A weight retraction device for use with a waterfowl decoy includes a housing having a spool rotatably coupled thereto. A weight is attached to a line that is wound around the spool. Rotation of the spool in a first rotational direction causing an unwinding of the line from the spool to cause the weight to extend away from the housing while rotation of the spool in a second rotational direction causing a rewinding of the line back onto the spool to cause the weight to retract back towards the housing. A power spring is configured to urge the spool to rotate in the second rotational direction. A lock release mechanism is configured to normally be in a locked configuration for preventing an undesired rotation of the spool in the second rotational direction. A manual actuation of the lock release mechanism releases the locked configuration of the lock release mechanism.

A lanyard having a locking mechanism is provided. The lanyard locking mechanism actuates between a locked position and an unlocked position. In the locked position, the lanyard spool is restricted from rotating, and in the unlocked position, the lanyard spool is permitted to rotate with reduced interference from the locking mechanism. The locking mechanism includes biasing components that bias the locking mechanism to remain stationary unless sufficient force is exerted.

an improved type of cable reel structure is disclosed, in which a sufficiently thick cable is used, which facilitates an operation of winding or unwinding the cable and which can prevent the cable from being twisted or disturbed in a repeated cable storage or withdrawal process and from being reduced in operability.
