Abstract: A selectively operable braking device for an elevator system. The braking device includes a safety brake adapted to be wedged against a guide rail when moved from a non-braking state into a braking state. Also included is an engagement mechanism moveable between an engaged position and a non-engaged position, the engagement mechanism comprising bar pinions each having teeth and connected to at least one of the other bar pinions with a meshed engagement of the teeth, the engagement mechanism configured to move the safety brake between the non-braking state and braking state when the engagement mechanism moves between the non-engaged position and the engaged position. Further included is a plurality of magnetic brake pads, each of the brake pads coupled to one of the bar pinions, wherein movement of one of the brake pads into the engaged position causes movement of the other magnetic brake pads into the engaged position.

Abstract: A braking system resetting mechanism for a hoisted structure includes a guide rail (14) and a brake member (10). Also included is a brake member actuation mechanism (12) operatively coupled to the brake member and configured to magnetically engage the guide rail to actuate the brake member from a non-braking position to a braking position. Further included is an outer structure having a slot (64) configured to guide the brake member actuation mechanism, wherein the slot includes a first angled region and a second angled region that intersect at an outer location. Also included is a spring loaded lever (202) operatively coupled to the outer structure and configured to engage the brake member actuation mechanism during a resetting operation, wherein the spring loaded lever biases the brake member actuation mechanism toward the outer location of the slot of the outer structure to disengage the brake member actuation mechanism from the guide rail.

Abstract: An illustrative example elevator sill assembly includes a sill plate and at least one support arm secured to the sill plate. A mounting bracket is configured to be mounted to an elevator car. The support arm is supported on the mounting bracket to allow the support arm to pivot relative to the mounting bracket. At least one linear actuator has a moving portion that moves in a vertical direction to cause the at least one support arm to pivot relative to the mounting bracket to thereby cause the sill plate to pivot from a stored position to an actuated position.

Abstract: An illustrative example elevator sill assembly includes a sill plate and at least one support arm secured to the sill plate. A mounting bracket is configured to be mounted to an elevator car. The support arm is supported on the mounting bracket to allow the support arm to pivot relative to the mounting bracket. At least one actuator arm has a portion configured to be contacted by a door of the elevator car to cause movement of the actuator arm relative to the mounting bracket as the door moves into an open position. The movement of the actuator arm causes the support arm to pivot relative to the mounting bracket to thereby cause the sill plate to pivot from a stored position to an actuated position.
