Abstract
According to one embodiment of the present invention, a side rail is provided having a body selectably movable from a first up position to a second down position. Two parallel lever arms are also provided. The arms rotate over center when moving the body between the two positions. This increases the horizontal distance through which the side rail moves. A biasing mechanism can be provided to urge the side rail towards either the up or down position, and to bias away from an intermediate toggle position wherein the lever arms are vertical in a preferred embodiment. The biasing mechanism can include a cam and roller. A hard stop can be provided, whereby in the up position there is a strong component to prevent failure. A release lever is also provided. A person can actuate the release lever to move the side rail from the up position.
