Operating/display panel

An illustrative example elevator system device includes an interface configured to operate in a first mode that allows an elevator passenger to communicate with the elevator system. The elevator passenger may communicate with the elevator system by inputting an indication for desired elevator service or receive an indication regarding elevator service. A magnetically actuated switch selectively causes the interface to operate in a second mode that allows an authorized individual to communicate with the elevator system in a manner that is different than an elevator passenger communication in the first mode. The magnetically activated switch includes at least one magnet and at least one switch contact that changes between an open and closed state based on an interaction between the at least one magnet and a magnetic key brought into proximity of the at least one magnet by the authorized individual.

Elevator system device with authorized access control

A systemincludes an input/outputunit for receiving a user request to call an elevatorand a processorfor processing the user request to assign an elevator to the user. The processor performs one of a first assignment process and a second assignment process. The first assignment process includes determining whether a delay condition exists for delaying assignment of the elevator to the user, delaying assignment of the elevator to the user based on determining that the delay condition exists, and assigning the elevator to the user based on determining that the delay condition does not exist. The second assignment process includes assigning the elevator to the user and notifying the user of the assignment, determining whether an assignment change condition exists, changing the assignment to another elevator based on determining that the assignment change condition exists, and notifying the user of the assignment change

Variable elevator assignment

An exemplary brake device includes a brake element configured to apply a braking force to resist rotation of an associated component. A mounting member is configured to mount the brake device to a stationary surface. The mounting member is at least partially moveable relative to the stationary surface responsive to a torque on the brake device. A sensor provides an indication of a force associated with any movement of the mounting member relative to the stationary surface responsive to the torque.

Brake torque control

A brake for machine and method of using the brake is disclosed. The brake may comprise first and second brake linings configured to be frictionally engageable with a rail, a first biasing member configured to urge the first brake lining to engage the rail, and a first actuator configured to move the first brake lining () to disengage the rail when the first actuator is energized. The brake may be configured to be mounted on a machine, floor or the like.

Brake

A brake () for an elevator system () and method of using the brake () is disclosed. The brake () may comprise first and second brake linings () configured to be frictionally engageable with a rail () of the elevator system (), a first biasing member () configured to urge the first brake lining () to engage the rail (), and a first actuator () configured to move the first brake lining () to disengage the rail () when the first actuator () is energized. The brake () may be configured to be mounted on an elevator car () of the elevator system ().

Elevator brake

An elevator system includes one or more rails fixed in a hoistway and an elevator car configured to move through the hoistway along the one or more rails. The system includes one or more braking systems having one more braking surfaces secured to the elevator car and frictionally engageable with one or more rails of the elevator system. One or more actuators are operably connected to the one or more braking surfaces configured to urge engagement and/or disengagement of the one or more braking surfaces with the rail to stop and/or hold the elevator car during operation of the elevator system.

Elevator braking system

An exemplary elevator door frame includes a sill member and a header member. A plurality of jamb members are generally perpendicular to the sill member and the header member. A plurality of guide rail brackets are supported on at least one of the sill member, the header member or one of the jamb members. The guide rail brackets are configured to receive a portion of a guide rail.

Elevator system door frame that supports guide rails

An exemplary door frame assembly that is useful in an elevator system includes a plurality of door frame members including a header, a sill and a plurality of jambs. The door frame members are configured to be secured into a desired position along a hoistway. At least one guide rail bracket is supported by at least one of the door frame members. The guide rail bracket is moveable relative to the door frame member between a handling position in which the guide rail bracket is generally parallel to at least one of the header or the sill and a deployed position in which the guide rail bracket is generally perpendicular to the at least one of the header or sill.

Elevator system with guide rail bracket

A feedback system for a motor of an elevator system is provided. The feedback system may include a first sensor and a processing circuit. The first sensor may be disposed in proximity to a drive component of the elevator system and configured to detect a change in position of the drive component. The processing circuit may be configured to receive a first data signal from the first sensor corresponding to the change in position of the drive component and generate a feedback signal for controlling the motor based on the first data signal.
