摘要:
A safety mechanism for a gate having first and second ends, a first fulcrum point intermediate the first and second ends and a first rotational axis proximate the second end, the safety mechanism including a first force resisting means intermediate the first fulcrum point and the first rotational axis, wherein a force applied to the first end is transmitted toward the first rotational axis via the first fulcrum point and the first force resisting means prevents transmission of the force to the first rotational axis. The present invention also comprises a safety mechanism for a gate having first and second ends, a locking means and a first rotational axis proximate said second end, wherein a force applied to the first end is transmitted toward the first rotational axis via the locking means, the safety mechanism including a first force resisting means intermediate the first rotational axis and the force, wherein the first force resisting means prevents transmission of the force to the first rotational axis.
