Abstract
A safety apparatus () includes a frame unit () placed on a surface (). A cable () is mounted around a pulley () rotatably mounted to the frame unit () about a rotation axis (). A slide () is slideably mounted to the frame unit () along a slide axis () at a non-parallel angle to the rotation axis () and movable between upper and lower positions. The cable () is attached between the slide () and a worker () on the surface (). A biasing member () is mounted between the slide () and the frame unit () and biases the slide () from the lower position to the upper position. An engaging member () is mounted to the slide () to move therewith. The engaging member () is above the surface () when the slide () is in the upper position. If the worker () falls from the surface, the engaging member () is moved downward and grips the surface () under the action of force resulting from falling of the worker () to retain the safety apparatus () on the surface and, thus, arrests the fall of the worker () from the surface ().
