Dual directional gate assembly

A dual directional gate assembly for controlling back and forth movement of an object that extends into a slot formed in a track, said dual directional gate assembly, comprising:

• a. a gate box aligned longitudinally inside said track;
• b. a driver shaft transversely aligned inside said gate box;
• c. a blocking arm affixed to said driver shaft, said blocking arm includes an upward extending protruding element configured to make contact with said object moving back or forth in said slot, said protruding element configured to contact said object traveling along said slot and cause said driver shaft to rotate in the direction of movement of said object;
• d. a cam element affixed to said driver shaft, said cam element includes a protruding element that extends upward and rearward from said driver shaft;
• e. a push rod affixed to said driver shaft, said push rod includes a protruding element that extends upward and rearward from said driver shaft;
• f. at least one spring coupled to said driver shaft configured to rotate said driver shaft so that said protruding element on said blocking arm returns to an upright extending position and contacts said object moving along said slot;
• g. a driven shaft transversely aligned inside said gate box;
• h. a latch with a front arm, said latch being, mounted on said driven shaft and configured so that said front arm extends diagonally upward and towards said protruding element on said cam element to block rotation of said cam element towards said driven shaft;
• i. a follower rod mounted on said driven shaft, said follower rod includes a distal end and a proximal end located on opposite sides of said driver shaft, said proximal end being sufficient in length to extend under said protruding element on said push arm;
• j. a solenoid released arm sub-assembly pivotally mounted at one end to said gate box adjacent to said distal end of said follower rod, said solenoid release arm sub-assembly includes a stop surface that extends under said distal end of said follower rod and blocks downward rotation of said distal end of said follower rod;
• k. a solenoid that includes a piston arm coupled to said solenoid release arm sub-assembly, when said solenoid is activated said piston moves and causes said solenoid release arm sub-assembly to rotate and disengaging said stop surface from said distal end of said follower rod;
• and
• l. a spring coupled to said proximal end of said follower rod and coupled to said latch, said spring configured to create an upward biasing force to said proximal end of said follower rod and an upward biasing force to said front arm on said latch upward that forces said proximal end of said follower rod diagonally and towards said cam element.
