US 2006/0214024 A1 · CABLE MANAGEMENT APPARATUS

Abstract

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.

Dependent claims

In a fire fighting water monitor having a stationary element and a rotating element for directing a water stream at variable trajectories, the monitor including at least one electrical component mounted to the rotating element and at least one wire connecting the electrical component to an electrical source independent of the monitor, the improvement comprising:

a wiring skirt housing an intermediate section of the wire and configured to accommodate relative rotation between the stationary and rotating elements of the monitor, said wiring skirt including;
a first portion configured for mounting to the stationary element, the first portion defining a first opening sized for passage of said intermediate section of the wire therethrough for connection to the electrical source;
and
a second portion configured for mounting to the rotating element, the second portion defining a second opening sized for passage of said intermediate section of the wire therethrough for connection to the electrical component,
wherein said first and second portions are configured to rotatably mate and are further configured to define a circumferential channel in communication with said first and second openings, said channel sized to receive said intermediate section of the wire with said intermediate section forming a 180° bend between one portion entering said first opening and another portion exiting said second opening.
