Abstract:
A vehicle activated collapsible gate movable between a closed raised position and an open lowered position comprising, a gate framework mounted for pivotal movement about a generally horizontal axis and lying substantially in a vertical plane when in closed raised position, a pair of spaced operating mechanisms for moving the gate structure to a lowered position, each of said operating mechanisms including an elongated generally horizontally extending member which extends substantially perpendicular to said plane and extends a substantial distance on opposite sides of said plane when the framework is in the closed raised position, each generally horizontally extending member having a substantially flat upper surface for supporting wheels of a vehicle and being pivotally connected to said gate structure, each operating mechanism also including a pair of support members each of which is mounted for pivotal movement about a generally horizontal axis and is pivotally connected to the generally horizontally extending member of the associated operating mechanism, and closing means normally biasing said gate structure into raised position.
