Abstract

A cable tray apparatus is provided for a people mover system such as a Sky Train or the like. The cable tray apparatus is made up of a plurality of identical cable trays which are secured together in an end-to-end relationship. The cable trays are selectively laterally horizontally adjustable with respect to one another and are selectively vertically adjustable with respect to one another to correspond to curves in the roadway of the system and to correspond to elevational changes in the roadway of the system. Each of the cable trays includes a cover having an upstanding tactile warning device at the side edges thereof. A light is also associated with each of the tactile warning devices.

Claims

1. In combination:

an electric train which travels along a power rail positioned on a roadway with the train including one or more cars having opposite sides;

a plurality of generally rectangular electrical cable trays having first and second ends;

said cable trays being connected together in an end-to-end relationship;

said cable trays being positioned on the roadway at one side of the cars of the train;

each of said cable trays including a body portion having a bottom wall with first and second ends and first and second upstanding side walls with upper ends;

each of said cable trays including a cover, having a first end, a second end, a first side edge and a second side edge;

said cover having an outer surface and an inner surface;

said cover being selectively movable between a closed position and an open position;

said cover, when in its said closed position extending between said upper ends of said first and second side walls;

a first elongated and horizontally disposed tactile warning device, having first and second ends, extending upwardly from said outer surface of said first side edge of said cover;

said first tactile warning device extending between said first and second ends of said cover whereby said first end of said first tactile warning device is positioned adjacent said first end of said cover and said second end of said first tactile warning device is positioned adjacent said second end of said cover;

a second elongated and horizontally disposed tactile warning device, having first and second ends, extending upwardly from said outer surface of said second side edge of said cover;

said second tactile warning device extending between said first and second ends of said cover whereby said first end of said second tactile warning device is positioned adjacent said first end of said cover and said second end of said second tactile warning device is positioned adjacent said second end of said cover;

each of said first and second tactile warning devices comprises an elongated horizontally disposed first plate having a first end, a second end, an inner end and an outer end with said first plate being secured to said outer surface of said cover;

each of said first and second tactile warning devices having an upstanding second plate, having upper and lower ends, which extends upwardly from said outer end of said first plate thereof;

each of said first and second tactile warning devices having at least one upstanding third plate, having upper and lower ends, which extends upwardly from upper end of said second plate thereof;

each of said first and second tactile warning devices having a fourth plate secured to said third plate thereof which extends inwardly therefrom; and

a light positioned below said fourth plate for illuminating said cover.

2. The combination of claim 1 wherein said cover is hingedly secured to one of said first and second side walls of said body portion.

3. The combination of claim 1 wherein said cover includes first and second cover members.

4. In combination:

an electric train which travels along a power rail positioned on a roadway with the train including one or more cars having opposite sides;

a plurality of generally rectangular electrical cable trays having first and second ends;

said cable trays being connected together in an end-to-end relationship;

said cable trays being positioned on the roadway at one side of the cars of the train;

each of said cable trays including a body portion having a bottom wall with first and second ends and first and second upstanding side walls with upper ends;

each of said cable trays including a cover, having a first end, a second end, a first side edge and a second side edge;

said cover having an outer surface and an inner surface;

said cover being selectively movable between a closed position and an open position;

said cover, when in its said closed position extending between said upper ends of said first and second side walls;

a first elongated and horizontally disposed tactile warning device, having first and second ends, extending upwardly from said outer surface of said first side edge of said cover;

said first tactile warning device extending between said first and second ends of said cover whereby said first end of said first tactile warning device is positioned adjacent said first end of said cover and said second end of said first tactile warning device is positioned adjacent said second end of said cover;

a second elongated and horizontally disposed tactile warning device, having first and second ends, extending upwardly from said outer surface of said second side edge of said cover;

said second tactile warning device extending between said first and second ends of said cover whereby said first end of said second tactile warning device is positioned adjacent said first end of said cover and said second end of said second tactile warning device is positioned adjacent said second end of said cover;

each of said first and second tactile warning devices comprises an elongated horizontally disposed first plate having a first end, a second end, an inner end and an outer end with said first plate being secured to said outer surface of said cover;

each of said first and second tactile warning devices having an elongated angle member, having inner and outer ends, positioned outwardly of said outer end of said first plate;

each of said first and second tactile warning devices having an upstanding second plate with upper and lower ends extending upwardly from said outer end of said angle member;

each of said first and second tactile warning devices having a third plate which extends inwardly from said upper end of said second plate; and

a light positioned below said third plate for illuminating said cover.
