Abstract: A handrail drive for a passenger conveyor includes a drive belt that does not emcompass either the main drive shaft or the handrail drive shaft. In a particular embodiment, the drive belt includes a plurality of outwardly extending teeth and is formed from a reinforced elastomeric material. The teeth are engaged with complementary toothed extensions on the main and handrail drive shafts. Two pairs of deflection rollers maintain contact between the drive belt and drive shafts and an adjustable spring maintains tension in the drive belt.

Abstract: A passenger sensor (42) for a passenger conveyor (10) is disposed adjacent to a floorplate (28) and produces a signal in response to changes in the load on the floorplate, rather than in response to a predetermined level of load. This results in a passenger sensor that does not require adjustment to accommodate the changing conditions of the passenger conveyor. In a particular embodiment, the passenger conveyor includes a passenger sensor that is formed from a piezoelectric cable that extends about the perimeter of the floorplate. The piezoelectric cable is connected to a controler (26) that determines the operational speed of the passenger conveyor. Changes in the load on the floorplate, such as caused by a passenger entering the passenger conveyor, result in the piezoelectric cable generating a signal that is received by the controller. The controller then adjusts the operation speed of the passenger conveyor in response to the signal.

Abstract: A control system for controlling the motion of a hydraulic elevator calculates a deceleration distance based upon the elevator velocity and begins the deceleration phase of the elevator motion upon the elevator reaching the calculated distance from the landing. In a particular embodiment, the control system includes a hydraulic valve (38), a space encoder (16), and a controller (42). The space encoder (16) produces velocity and position measurements. The controller (42) uses the velocity inputs to determine the deceleration distance and, upon the elevator car (14) reaching the calculated distance from the landing as measured by the position inputs from the space encoder (16), commands the hydraulic valve (38) to actuate and begin the deceleration phase. In an alternate embodiment, an interface unit (56) connected between the controller (43) and the hydraulic valve (38) calculates a delay between the deceleration command based upon a predetermined distance and the calculated deceleration distance based upon car velocity. Upon expiration of the delay, the interface unit (56) commands the hydraulic valve (38) to actuate and begins the deceleration phase.

Abstract: An apparatus for controlling an adjustable-speed alternating current motor coupled to drive an elevator cage. The apparatus includes a converter connected to a source of AC power for converting the AC power into DC power, an inverter connected through relatively positive and negative conductors to the converter for inverting the DC power into AC output power having adjustable frequency, voltage magnitude, and current magnitude to drive the motor, and a control circuit for controlling an inverter to drive the motor at an adjustable speed. When a power failure occurs, the control circuit prevents flow of power through the converter to the power source and reduces the current magnitude of the inverter output power to a predetermined minimum limit enough to maintain a synchronous relationship between the inverter and the motor. When the power failure continues for a predetermined time, an electric resistor is connected between the relatively positive and negative conductors to provide a dynamic braking of the motor.

Abstract: A control system for a passenger conveyor includes a ready-to-operate mode, a standby speed and a nominal speed. A method to operate the passenger conveyor includes the steps of: transitioning the conveyor from ready-to-operate mode to nominal speed using a frequency converter; switching from frequency converter to line power at nominal speed; switching back to frequency converter if no passengers are present and transitioning from nominal to standby speed; and transitioning from standby speed to ready-to-operate mode if a predetermined amount of time passes without a passenger entering the conveyor.

Abstract: A simplified elevator car door lock assembly locks an elevator car door if the car is outside a landing zone and there is an attempt to open those doors. The car doors are connected to the hoistway doors by a pair of vanes (34, 36) mounted on the car door and a pair of rollers (29a, 29b) mounted on the hoistway door. A third vane (38) is attached to the car door and follows a cam path on the car door to lock the car doors if the car is not in a landing zone. Conversely, the third vane senses if the car is in a landing zone and does not lock the car door if it is moved.

Abstract: A pallet sensor assembly for a passenger conveyor includes a proximity sensor and a limit switch. The proximity sensor detects the presence of the pallets and the limit switch monitors the wear of the pallet assembly. Neither sensor is in direct contact with the pallets during normal operation of the passenger conveyor. Both sensors are mounted and positioned on a single frame that is then mounted onto the pallet assembly. The pallet sensor assembly is positioned such that the passenger conveyor may be stopped prior to exposure of the opening caused by the missing pallet or exposure of the worn pallet to the passengers.
