ABSTRACT:
An improved straight line motion gate mechanism which translates gate position to an open/closed position without any perceptible vertical motion and without any moving contact with either the ground or the use of a track. The gate may assume a wide range of widths and the mechanism may be self locking in the closed and open positions. A very small vertical motion of the mechanism provides for minimal input energy requirements and is relatively insensitive to gate weight.
