Abstract: A braking device is operable to aid in braking a hoisted object relative to a guide member. The braking device includes a mounting structure connected to the hoisted object, and first and second brake pads positioned on the mounting structure on opposing sides of a passageway through which the guide member extends. The first and second brake pads each include a contact surface that is operable to frictionally engage the guide member. The second brake pad engages the mounting structure in a manner that enables the second brake pad to move relative to the mounting structure between a non-braking position and a braking position. The braking device includes a brake initiator that is selectively operable to initiate movement of the second brake pad from the non-braking position toward the braking position by selectively actuating an actuatable portion of the brake initiator from a non-deployed position to a deployed position.

Abstract: An exemplary elevator guiderail includes a metal sheet bent into a configuration that establishes at least one mounting portion configured to facilitate mounting the guiderail within an elevator hoistway. At least one guiding portion is configured to guide movement of an elevator car along the guiderail. The metal sheet includes an exterior surface treated to resist corrosion. A cover over at least some of the guiding surface has an exterior that is different than the exterior surface of the metal sheet. The cover is configured to establish a coefficient of friction to facilitate brake engagement with the cover for resisting movement of an elevator car along the guiderail.

Abstract: Elevator systems including an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side and a structural sound-generation system. The structural sound-generation system having at least one audio actuator coupled to the second side of the first elevator car component and an audio system controller in communication with the at least one audio actuator. The structural sound-generation system is configured to generate vibrations within the first elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car.

Abstract: A device for a friction force provider for an emergency safety actuator for an elevator is disclosed. The friction force provider may include a housing having a first end and an opposing second end, where the first end may define an opening. The friction force provider may further include a primary magnet positioned within the housing and configured to move between an armed position and a working position. The primary magnet may be configured to create a force on a rail of an elevator system in the working position and be held within the housing in the armed position.
