发明名称 Safety gate for loading dock lift
摘要 A safety barrier for a loading dock lift that includes a lift platform that can be raised and lowered. The safety barrier includes a sleeve attached to the lift platform extending along a vertical axis. The sleeve includes guides to define open and closed positions of said gate and said shaft includes a pin that interacts with the guides to produce rotation of said gate between open and closed positions. Consequently each embodiment gate automatically closes due to gravity whenever the lift is raised off the ground and thereby assures that that gates are locked in position when the lift platform has been raised a short distance.

主权项 1. A safety barrier for a lift platform that moves between a bottom position and an upper position, said safety barrier comprising: A) a sleeve attached to the lift platform extending along a vertical axis, and B) a gate having a barrier attached to an upper portion of a shaft wherein a bottom portion of said shaft extends through and is rotatable within said sleeve, said sleeve includes a guide that is shaped to define open and closed positions of said gate and said shaft includes a pin at a position along said shaft that extends through said guide, wherein when the pin interacts with the guide in the closed position, the gate is closed and when the pin interacts with the guide in the open position, the gate is opened as the lift platform is moved between said bottom position and said upper position.
