Abstract
A safety edge assembly is provided for an electronic sensor system in an elevator doorway. A narrow elongated transmitter frame mounts appropriate electronic transmitting components of the system thereon and is fastened vertically on one side of the doorway. A narrow elongated receiver frame mounts appropriate electronic receiver components of the system thereon and is fastened vertically on the opposite side of the doorway. A power supply frame mounts appropriate electronic power components of the system thereon and is fastened in a piggyback fashion on the transmitter frame. Electrical cables are coupled between the electronic components on opposite sides of the doorway, the cables extending across the top of the doorway.

A safety edge assembly for an electronic sensor system in an elevator doorway, comprising:
- a narrow elongated transmitter frame for mounting appropriate electronic transmitting components of the system thereon;
- means for fastening the transmitter frame vertically on one side of the doorway;
- a narrow elongated receiver frame for mounting appropriate electronic receiver components of the system thereon;
- means for fastening the receiver frame vertically on the opposite side of the doorway;
- a high power supply frame for mounting appropriate electronic power components of the system thereon and including a high power cable leading to an appropriate high power source;
- means for fastening the high power supply frame in a piggyback fashion on the transmitter frame;
- and
- low power electrical cable means coupled between the electronic components on opposite sides of the doorway and extending across the top of the doorway.
In a safety edge assembly for an electronic sensor system in an elevator doorway, the assembly including a transmitter frame on one side of the doorway for mounting appropriate electronic transmitting components of the system thereon, and a receiver frame on the opposite side of the doorway for mounting appropriate electronic receiver components of the system thereon, wherein the improvement comprises:
- said transmitter and receiver frames comprising narrow elongated extruded members, each frame being generally channel-shaped in cross-section to define a pair of side leg portions joined by a bight portion providing a cavity for mounting the appropriate electronic components therewithin,
- mounting means integral with the inside of the leg portions of the channel-shaped frames for facilitating mounting the electronic components,
- means on the bight portion of each frame for facilitating fastening of the frame to an appropriate support structure such as an elevator door and a door jamb,
- a high power supply frame for mounting appropriate electronic power components of the system thereon and including a high power cable leading to an appropriate high power source,
- means for fastening the high power supply frame in a piggyback fashion on the transmitter frame, and
- low power electrical cable means coupled between the electronic components on opposite sides of the doorway and extending across the top of the doorway.
