A safety gate comprises a counterbalanced gate structure which consists of two side parts connected at one end by a fence part and which is pivotably mounted on a supporting structure by way of the said side parts to permit the gate structure to be swung between two end positions, and stop means pivotably mounted in relation to the supporting structure, preferably on the pivot for the gate structure, and automatically engageable with the supporting structure and by the side parts of the gate structure for determining the said end positions. Extensions telescopically adjustable longitudinally in relation to the side parts may be provided for adjustably counterbalancing the gate structure. The stop means advantageously comprises a stop plate pivotably mounted, between parts of the gate and supporting structures, on a pivot pin fixed in the said part of the latter. |
