Invention relates to a device for supporting and operating a cable drum, equipped with a rectangular frame and a locking-release mechanism, including a sliding carriage equipped with tensioning that is mounted on the main frame. The sliding carriage is in the shape of a rectangle, open on one side, which is the front part of a sliding carriage, in addition, the main frame is equipped with a locking-release mechanism mounted on both sides. In the center of the front transverse part of the main frame there is a winch connected to the drive; in the longitudinal part, the main frame consists of two parallel semi-closed channels, and in the center of each semi-closed channel of the longitudinal part of the main frame there are support rollers, which are attached to a sliding carriage mounted on the main frame; a triangular boom with swivel arms is mounted in the front, open part of the sliding carriage by means of bolts; in the upper part of each of the swivel arms of the triangular boom.

A reel system may receive a leading edge of a flexible buoyant pad. The flexible buoyant pad may have a use configuration having a first outer vertical envelope and a storage configuration having a second outer vertical envelope that is smaller than the first outer vertical envelope. The reel system may comprise at least one base member, an arm rotatably coupled to the base member and a rotatable axle coupled to the arm. The rotatable axle may be rotatable relative to the arm and the rotatable axle may adapted to receive the flexible buoyant pad and support the flexible buoyant pad in the storage configuration. Further, an actuatable input may supported by the arm. The actuatable input may be configured to rotate the rotatable axle relative to the arm.

An emergency bi-fold door closing prevention system includes a building having an access opening with an upper edge. A bi-fold door is hingedly mounted to the building wall and includes a plurality of panels each being laterally elongated. The plurality of panels includes a bottom panel having a bottom edge that is positionable adjacent to a floor surface to define a closed position. A safety line assembly is attached to and extends between the building wall adjacent to the upper edge and the bi-fold door adjacent to the bottom edge. The safety line has an extendable length. The length of the safety line assembly extends when the bi-fold door moves toward the closed position below a threshold velocity. The length of the safety line assembly is inhibited from extending when the bi-fold door moves toward the closed position above the threshold velocity.

A cable management system for an electric vehicle charger includes a transfer lever pivotably mounted at a pivot point. A sensor may be mounted to be aligned with a portion of the transfer lever. A mechanical wire may be coupled to a charging cable associated with the electric vehicle charger. The cable management system may include a force transmission coupler connected to the transfer lever. The force transmission coupler may receive the mechanical wire and transmit a force applied to the mechanical wire to the transfer lever to cause the transfer lever to pivot from the first orientation to the second orientation to apply a greater pressure to the sensor. A wire retractor retracts and extends the mechanical wire based on sensor data.

There may be provided a cable management system for an electric vehicle charger. The cable management system may include a mechanical wire coupled to a charging cable associated with the electric vehicle charger and an enclosure. The cable management system may include a wire tension sensor engaging the mechanical wire. The wire tension sensor may generate a sensor output based on a force applied to the mechanical wire. The wire retractor may be configured to retract the mechanical wire into the enclosure and extend the mechanical wire from the enclosure. The cable management system may include a controller coupled to the wire tension sensor. The controller may be configured with instructions which, when executed, cause the controller to control the wire retractor based on an amount of force applied to the mechanical wire.

A reversible drive assembly for a retractable pool cover apparatus having a drive shaft extending along a longitudinal axis. The drive shaft is selectively rotated in a first rotational direction or a second rotational direction about the longitudinal axis by a drive motor and includes a first pin aperture and a second pin aperture. A first gear engages the drive shaft and forms a first slot angled at a first guide angle in a first direction relative to the longitudinal axis. A second gear engages the drive shaft and forms a second slot angled at a second guide angle in a second direction relative to the longitudinal axis. A gear pin is configured to engage the first pin aperture and the first slot in a first configuration or the second pin aperture and the second slot in a second configuration.

A reel assembly (100) for coupling within a housing (160) includes an axle (110) and a reel (120) defining a rotational axis (X-X). The reel (120) is rotatably mounted around the axle (110) to allow winding of a flexible linear component (130) on the reel (120). The reel assembly (100) further includes a frame (140) which houses the reel (120). Moreover, the reel assembly (100) includes one or more fixing units (150) to removably fix the reel assembly (100) inside the housing (160). The reel assembly (100) is characterized in that the reel assembly (100) further includes a blocking mechanism (170) that operatively couples with the reel assembly (100) and cooperates with the reel (120) for selective rotation of the reel (120). The blocking mechanism (170) disallows rotation of the reel (120) in absence of coupling of the reel assembly (100) within the housing (160).

A reel enclosure includes a base and a door pivotally coupled with the base. The door is movable between a first closed position and a second open position and is configured to hold a reel at an interior surface of the door. The reel is configured to have cable wound thereon. In the first closed position, the base is configured to prevent the reel from rotating relative to the door and the base, and, in the second open position, the door is configured to hold the reel outside of an interior of the base and permit the reel to rotate relative to the door and the base.
