A cord management system for furniture includes an elongated flexible member having a plurality of cable clip elements attached thereto for attachment to multiple cables to retain the cables near the elongated member. The elongated flexible member is resilient and is configured for attachment to an article of furniture, such as a table, that is vertically moveable from a first lowered position to a second raised position. For example, when the article of furniture is in the raised position, the elongated member can be extended to a first position in which the member resembles an “S’ shape, a “∫” shape, a “” shape, or a backward “S” shape, e.g. “” shape and when the article of furniture is in the lowered position, the elongated member can be compressed to a curved compressed configuration that is “{tilde over ( )}”, “” or “” in shape.

A cable management system for an electric vehicle (EV) charging station comprises an upstanding enclosure having a cable opening though which an EV charging cable can be pulled for extension. The EV charging cable is provided at a free end thereof with an EV charging connector for connection with an EV charging socket of an EV. The EV charging cable is provided at an opposed fixed end thereof with an electric connector for connection with a mating connector mounted inside the enclosure. A fixed pulley is mounted within the upstanding enclosure for rotation about a first axis normal to an upstanding axis of the enclosure. The system further comprises a mobile pulley rotatable about a second axis parallel to the first axis. The mobile pulley is vertically translatable within a guiding structure mounted inside the upstanding enclosure for movement towards and away from the fixed pulley. The fixed pulley is mounted at a higher elevation than the mobile pulley. The EV charging cable extends over the fixed pulley and the mobile pulley between its opposed free and fixed ends. The mobile pulley is moveable against gravity from a lowered position to a raised position by the application of a sufficient pulling force at the free distal end of the EV charging cable. The mobile pulley returns at least partly under gravity to its lowered position upon release of the EV charging cable, thereby automatically retracting the cable inside the upstanding enclosure.

A portable winch suitable for use in underground pipe bursting and replacement includes a mounting frame positionable at a top opening of a hole such as a receiving pit or manhole. A telescoping mast having a series of nested, top and bottom mast sections is mounted on the frame. A powered winch unit, also mounted on the frame, includes a drive unit and a cable. A guide assembly includes a sheave that guides the cable from the drive unit to the bottom mast section. Suitable means are connected to the frame for mechanically raising and lowering the mast into and out of the hole. As such, the mast according to the invention does not require assembly or disassembly at the beginning and end of each job. The mechanical means for raising and lowering the mast is preferably the powered winch unit.

A link arm is rotatably supported by a rotating shaft along a protector base, and urged in a harness-slack-absorbing direction by a torsion coil spring. A wiring harness is fixed to a harness-holding member at a tip end of the link arm and to a harness-fixing portion of the protector base, and routed flexibly between the harness-holding member and the harness-fixing portion via between the protector base and an opposite wall of the link arm opposite to the protector base.

A power supply apparatus for a slidable structure which extends longitudinally, including: a pivotably-supported ring arm; a wiring harness having one end portion fixed to a tip portion of the ring arm and the other end portion fixed to a stationary structure; and an elastic member configured to bias the ring arm in a forward and upward direction. The ring arm is moved or rotated in a backward and downward direction while elastically deforming the elastic member due to tensile force of the wiring harness, when the slidable structure is moved forward toward its fully closed state. Also, the ring arm is moved or rotated in a forward and upward direction due to restoring force of the elastic member, when the slidable structure is moved backward toward its fully open state.

A fire fighting monitor includes a stationary element and a rotating element for directing a water stream at variable trajectories. Electrical components, such as drive motors, are mounted on the rotating element and are connected to electrical sources remote from the monitor. A wire management system is provided for the monitor that protects the electrical wiring while accommodating relative rotation between the stationary and rotating elements of the monitor. In one embodiment, the wire management system includes a two-piece wiring skirt with a first portion connected to the stationary element and a second portion connected to the rotating element. The two portions define a circumferential channel and associated openings for passage of a wiring cable. The cable incorporates a 180° bend within the channel that travels around the channel as the cable coils and un-coils within the channels of the two portions.

Devices and systems for tool-less assembly of cable chains that are capable of being retractably stored. The device comprises a first contact element, a second contact element, and a lengthwise member. The first contact element is adapted for movable contact with a receiving member of a first cable chain segment. The second contact element is adapted for movable contact with a receiving member of a second cable chain segment. The lengthwise member is fixedly attached to the contact elements. When an angle between the first and the second cable chain segments is a first value, the lengthwise member experiences elastic deformation, generating a spring force at each contact element sufficient to pull the receiving member of the first cable chain segment rotatably towards the receiving member of the second cable chain segment, thereby reducing the angle between the first and the second cable chain segments to a second value.
