A blocking assembly for a leaf of an elevator door comprises a translation guide, a first leaf carriage mounted slidably to the translation guide between a first position and a second position, a latch connected to the translation guide and rotatable between a blocking configuration of the first leaf carriage in an intermediate position wherein the latch intercepts and blocks the carriage against the guide, and a configuration for releasing the carriage wherein the carriage is free to slide to the second position, latch return means in the blocking configuration, and first coupling means connected to the first leaf carriage and to the latch. When the carriage is in the first position, the first coupling means are coupled together to keep the latch in the release configuration, in contrast to the action of the return means. When the carriage is in the intermediate position, the first coupling means are uncoupled so that the latch is moved by the return means into the blocking configuration.

The present invention relates to a safety device for preventing a hand from being caught by controlling an operation of opening/closing a door while reducing impact when a person's hand is jammed in a gap between an elevator door and a doorframe.

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.

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.

Elevator access systems are provided. The elevator access systems include a bushing having a keyway, a plunger disposed within the bushing and movable relative thereto, a lever operably connected to the plunger, and a removable plug located within the keyway of the bushing, wherein the removable plug urges the plunger and the lever into a first position, and upon removal of the removable plug, the plunger and the lever move to a second position, wherein in the second position the plunger is accessible to operate the lever.

A blocking device (2) for blocking access to an door unlocking device (118) of an elevator system (102) comprises: an outer element (4), which is introducable into an access opening (30) providing access to the door unlocking device (118); and an inner element (6), which is introducable into the outer element (4). The inner element (6) is configured for bringing the blocking device (2) into a fixing configuration, in which the outer element (4) is fixedly engaged with the access opening (30), by introducing the inner element (6) into the outer element (4).

Elevator landing door lock assemblies and elevator landing doors having a lock with a keyway accessible from a landing of an elevator system, the lock operable to lock and unlock a landing door and a disengageable link operably connected to the lock and configured to prevent unlocking of the landing door when the disengageable link is not engaged. When an elevator car is aligned with the landing door, the disengageble link is engaged and completed such that the lock is operable to unlock and open the landing door, and, when an elevator car is not aligned with the landing door, the lock is not operable.

An elevator door safety lock system ensures that an elevator door remains securely closed when it is not aligned with one of a plurality of floor openings. The safety lock system includes a vertical position sensor which includes an RFID reader disposed on the elevator and a plurality of RFID tags each disposed in the shaft at a different floor opening. The reader identifies when it is aligned or non-aligned with any tag indicating when the elevator is aligned and non-aligned with a floor opening. A control unit communicates with the safety lock system and an elevator controller. A door monitor indicates if the elevator door is open or closed and an engagement sensor detects whether the door lock is engaged.

A method for controlling a closing movement of a door of an elevator car in the event of a power failure uses the door drive and an electrical energy store. During normal operation of the door by the door drive, electrical energy is buffered in the energy store. In response to a power failure when the door is open, a closing mechanism begins to close the door and the stored electrical energy is provided as backup energy to the door drive by a control device to decelerate the closing movement.
