Traplock for bi-swing gate

An improved barrier fence and emergency exit gate system, comprising:

• a bi-swing gate able to swing in two opposite directions, and mounted on a first floor post by hinges;
• a second floor post for closing and latching a swinging end of the bi-swing gate and provided with a pocket;
• the improvement characterized by a traplock assembly comprising:
• a pair of gate catches mounted in said pocket and configured to catch and lock said swinging end of said gate between the pair of gate catches when said gate catches are in an extended position, and such that a retraction of either one of the gate catches permits a swing opening of the gate;
• a pair of pivot arms, each pivot arm having a pivot bearing at one end about which the pivot arm rotates, and each pivot arm connected to a respective gate catch at an opposite distal end, and fully disposed inside said pocket;
• a lock solenoid and pawl configured to lock the gate catches in extended positions;
• a retraction solenoid and pawl configured to move at least one of the pivot arms to a retracted position such that the gate may be opened;
• a sensor mounted to detect when the bi-swing gate has returned to a closed position, and to allow the lock solenoid and pawl to lock the gate catches in extended positions;
• each gate catch having a side-loading pad respectively positioned on an outermost side surface of the gate catches, and each side-loading pad limiting how far laterally the gate catches made be deflected when an attempt is made to force open an otherwise locked bi-swing gate;
• a post-mounting pocket positioned to the outer sides of the gate catches, and for limiting how far laterally the gate catches can deflect when an attempt is made to force open an otherwise locked bi-swing gate;
• and
• a failsafe device for automatically unlocking the gate catches if operating power is cut from the lock solenoid and pawl.

A turnstile system to accommodate ambulatory and handicapped persons in wheelchairs through a train station faregate or exit, comprising:

• a bi-swing gate mounted and configured to swing on a gate hinge and that can be latched closed;
• a pair of turnstile pedestals to provide support for said gate hinge and support for a latch provided in a pocket, and configured with electronic and electro-mechanical control systems to take tickets or tokens;
• an aisle provided for walk-through access bounded by a pedestal and controlled by a turnstile rotating bar;
• characterized by a traplock assembly comprising:
• a pair of gate catches mounted in said pocket and configured to catch and lock said swinging end of said gate between the pair of gate catches when said gate catches are in an extended position, and such that a retraction of either one of the gate catches permits a swing opening of the bi-swing gate;
• a pair of pivot arms, each pivot arm having a pivot bearing at one end about which the pivot arm rotates, and each pivot arm connected to a respective gate catch at an opposite distal end, and fully disposed inside said pocket;
• a lock solenoid and pawl configured to lock the gate catches in extended positions;
• a retraction solenoid and pawl configured to move at least one of the pivot arms to a retracted position such that the gate may be opened;
• a sensor mounted to detect if the bi-swing gate has returned to its closed position, and to enable the lock solenoid and pawl to lock the gate catches in extended positions;
• a pad positioned to the outer sides of the gate catches to limit how far laterally the gate catches made be deflected if force is applied to open an otherwise locked bi-swing gate;
• a post-mounting pocket positioned to the outer sides of the gate catches, and for limiting how far laterally the gate catches can deflect when an attempt is made to force open an otherwise locked bi-swing gate;
• and
• a failsafe device for automatically unlocking the gate catches if operating power is cut from the lock solenoid and pawl.
