Stabilizer for outside sliding plug doors

In an outside sliding plug door system of a type utilizing a door panel moving out of and away from an opening in a car side wall, a door panel stabilizer for preventing panel motion in an open position comprising:

• at least one door panel;
• said opening in a car side wall, alternately plugged and unplugged by said panel in moving from closed to open positions, respectively;
• means moving said panel out of said closed position to an open position along said car side wall adjacent said opening;
• and,
• means stabilizing said panel in an open position comprising:
• an arm on and extending from said car side wall, said arm having first and second ends;
• means mounting said arm first end in said car side wall for pivotal motion around said first end, said motion establishing a horizontal trajectory for said second end;
• a hook on said arm second end;
• elongated eyelet on said panel, said eyelet positioned to intersect said arm and hook trajectory when said panel is in an open position;
• means moving said arm through said trajectory when said panel is in an open position, said arm movement engaging said hook and eyelet;
• whereby engagement of said hook and eyelet captures and stabilizes said panel, preventing panel motion in an opened position.

In combination, an outside sliding plug door panel for use on a mass transit vehicle, said vehicle having an overhead power door operator for moving said panel out of and away from an opening in a side wall of said vehicle, and, a stabilizer for preventing panel motion and correcting panel sag when in an opened position comprising:

• a power door operator, overhead in said side wall opening;
• at least one rectangular panel for plugging and unplugging said opening, said panel having an upper corner on an inner edge, and an inner surface;
• a first position for said panel plugging said opening;
• said operator having attaching means at said panel upper corner for unplugging said opening and moving said panel to a second position away from said opening, said second position pivoting said panel downwardly around said attachment means;
• an elongated eyelet on said panel inner surface adjacent said side wall, said eyelet disposed below said panel attaching means;
• a hook extending from said side wall, said hook mounted for movement in a horizontal arc outside said side wall;
• means rotating said hook through said arc when said panel is in said second position, said arc intersecting said panel and engaging said eyelet, thereby displacing and pivoting said panel angularly upward.
