发明名称 Safety device for a crib
摘要 A safety device for a crib which provides an indicating light or alarm to alert a person to the fact that the crib gate is in a down position, to prevent the leaving of a child in a crib with the gate down and to insure that the crib gate is up and locked whenever the supervising person leaves the area or room. The device includes an illumination element and/or audible beeper having a switch that engages a structural portion of the crib gate when the gate is in a down position. The device may be readily installed on a conventional crib and may also provide subdued background lighting to allow observation of a child in the crib without disturbing the infant in the crib.
