Abstract:
An infant safety gate comprising:a gate member adapted to be pivotally mounted to a first generally vertical surface of a doorway opening such that said gate member is pivotable between an open position and a closed position to limit passage therethrough, said gate being sized such that said gate member spans a lower portion of said opening and does not span an upper portion of said opening; a latch, at least part of said latch being located on said gate member or adapted to be located on a second generally vertical surface of said opening, said latch being actuatable between a locked position, wherein pivotable movement of said gate member is prevented, and an unlocked position wherein said pivotable movement of said gate member is permitted; an actuator adapted to be mounted separately from said gate member for actuating said latch to said unlocked position, said actuator generating an infrared signal when activated, and wherein said latch includes a receiver for receiving said signal from said actuator and switching said latch to said unlocked position in response thereto, wherein said gate member is sized such that when said actuator is mounted adjacent to said doorway opening an operator can reach through said upper portion of said doorway opening to access and operate said actuator; and wherein said actuator includes an infrared emitter connected in line with an actuator transistor, an actuator controller for controlling an operative state of the actuator transistor, and a switch connected to the actuator controller, wherein the actuator controller is operable, in response to closure of the switch, to control the operative state of the actuator transistor to generate said infrared signal, said infrared signal comprising a coded multi-bit digital signal, wherein a digital 1 is represented by a 0.5 ms modulated pulse followed by a 0.5 ms delay and a digital 0 is represented by a 1.0 ms delay.
