An extendable and retractable earpiece cable assembly for mobile communication or sound devices including a housing integrally formed with or detachably connected to a casing for protecting a mobile electronic device. The housing receives a mechanism around which at least one earpiece cable is removably wound. The earpiece cable is extendable from and retractable into the housing.

The present invention relates to an electric retracting hose & cord reel. A reel body is connected with a driving motor through a driven gear and a driving gear. The driving gear is provided with an arresting disc and a locking device corresponding to the arresting disc. The driving motor and an electromagnet in the locking device are connected with a control plate. The control plate is connected with a locking switch and a motor on-off switch on an arresting block. The locking switch controls the electromagnet through the control plate to act. The motor on-off switch controls the driving motor through the control plate to be started and stopped. The locking device is arranged on the reel body, and a hose can be controlled through the locking device to continue to be pulled out in a locking position; and the locking device and the motor are remotely controlled wirelessly through the locking switch and the motor on-off switch so as to achieve that the pull-out and the retraction of the hose or cord of the electric retracting hose & cord reel are automatically controlled. Because an overload protection device is arranged on the control plate, it can ensure that when external resistance and sudden condition are encountered, the motor is emergently stopped and the reel body can stop rotating at any time, thereby performing a safety protection effect on an operator and a working environment.

A rollable display device includes a display panel for displaying an image, a printed circuit board connected to an edge of the display panel, and a roller which the display panel is rolled onto or unrolled from. The roller has a cylindrical shape having an inner space, and the printed circuit board is disposed in the inner space.

The cord reel device comprises a first reel body and a second reel body which are linked so that their rotational axes coincide; a pullout cord that is wound around the first reel body so that it can be pulled out; an internal cord that is wound around the second reel body in the same direction as the winding direction of the pullout cord; and a reel case that rotatably covers the first reel body and the second reel body and forms a winding space that allows free play of the internal cord. A convex portion that protrudes toward the rotational axis is provided to the reel case.

A reel system includes a hinged crank handle portion that turns a frame portion on an axis for winding and unwinding a coilable portion. The handle portion folds into the frame inner area, forming a flat surface on the flange, to allow for facilitated storage of a plurality of reel systems in a five gallon bucket. A frame portion rotates on an axis for winding and unwinding a coilable portion. The frame portion includes a frame outer area for engaging the coilable portion. The frame portion further includes a frame inner area for receiving and securing a terminal portion of the coilable portion. The terminal portion passes from the frame outer area to the frame inner area through a central aperture. A rod extends across the diameter of the frame inner area, forming a surface to grip the reel system.

The present invention relates to a novel firebox. The firebox is comprised of: a casing, a water swivel or main water hookup, one or more hose reels within the turning knob attached to the reel, a lay flat discharge hose with a standard water clamp, a plurality of screws for the base/water swivels rotation joint, and a plurality of rubber hose hooks for main water supply and T joint.

A tarp rolling device includes a handle bracket which includes a first section slidably engaging a second section such that the handle bracket has an adjustable width. A pair of ratcheting spools is removably mountable to the handle bracket and each of the ratcheting spools includes a plurality of rods which extend across a tarp to facilitate the tarp to be rolled into a roll when the pair of ratcheting spools are rotated. The handle bracket is urged to swing downwardly thereby facilitating the handle bracket to be rotated on each of the ratcheting spools. Continuing, the handle bracket is urged to swing upwardly subsequent to being urged downwardly thereby rotating each of the ratcheting spools to wrap the tarp around the plurality of rods.

A handling device includes a winch comprising a frame, intended to be attached to a structure of the surface vessel and a first drum capable of turning relative to the frame about a first rotation axis and an assembly comprising at least one second drum which surrounds the first drum and is capable of turning relative to the frame about a second rotation axis substantially parallel to the first rotation axis, the winch being capable of being in a decoupled state wherein the first drum and the second drum are rotationally decoupled about the first rotation axis and the second rotation axis so as to allow a traction cable to be wound around the first drum during a first winding step wherein the first drum is rotated about the first axis, the second drum being capable of being in an open state wherein the second drum has a receiving opening that a towed body is capable of passing through in order to enter the interior of the space that surrounds the first drum and that is surrounded by the second drum, the winch being capable of being in a coupled state wherein the first drum and the second drum are rotationally coupled about the second rotation axis so as to allow a flexible elongate body to be wound around the second rotation axis during a second winding step wherein the second drum is rotated about the second axis.

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. The cable reel can also include a locking pin for locking rotation of a flange with rotation of the drum.

A reel apparatus configured to wind, store, and dispense a flexible tensile member can include a rotor in a housing. The rotor can include receptacles that can be respectively positioned to receive a portion of a length of the flexible tensile member while the length simultaneously extends through opposite openings in the housing. A crank connected to the rotor can include a handle configured to be releasably locked to the housing in different positions. The flexible tensile member can be a strap of a ratchet strap system.
