A system for active and automated cleaning of interior surfaces and air within an enclosed space. The system is generally composed of an air cleaning sub-system, a surface cleaning sub-system, and an interface sub-system that is hands-free to prevent contacting fomites and spreading disease. The air cleaning sub-system employs a fan mounted above the enclosed space. In an elevator environment, this can easily be installed to avoid structural crosshead beams. Air is then pushed down through a flexible boot which includes a HEPA filter, pushing filtered and ionized air down past individual's heads and exhausted through the bottom of the enclosed space, such as the toe kick vents in an elevator environment. In this way, the air reaching the individuals within the space is clean, fresh, and has not made contact with other individuals within the space prior to being inhaled.

Elevators and elevator car wall panel systems are provided herein. The systems include an elevator car frame, at least two wall panels pivotally connected to the frame, a connecting element operably connecting the at least two wall panels, and an actuation element operably connected to the connecting element, wherein the actuation element is operable to transition the at least two wall panels from a closed state to an open state.

An elevator damping unit, for reducing vertical oscillation of an elevator car during a standstill period, has brake shoe retainers provided with brake shoes. The brake shoe retainers are connected to an electric motor via a toothed gear mechanism. The damping unit also includes a spring device configured as a metallic bending spring and arranged between the car and a carrier structure for the brake shoe retainers.

An elevator car includes a car-platform device including a car-platform panel, anti-vibration devices, and a car-platform support frame. The car-platform panel includes a panel main body, a frame structure including a panel frame surrounding an outer peripheral portion of the panel main body, and a panel upper plate and a panel lower plate for individually covering upper surfaces and lower surfaces of the panel main body and the panel frame. The anti-vibration devices receive the frame structure by upper surfaces thereof. The car-platform support frame supports the car-platform panel through an intermediation of the anti-vibration devices. The upper surfaces of the anti-vibration devices are arranged at a height position between an upper surface and a lower surface of the car-platform panel in a vertical direction.

A battery powered elevator system in which the battery and power electronics needed to connect the battery to the machine driving the elevator system are mounted in close proximity within the hoistway of the elevator system to minimize power transmission losses.

An elevator system has a car assembly including a first elevator car, a second elevator car, a counterweight, and a drive machine unit having a traction sheave and a traction device guided over the traction sheave. The traction device is connected to the car assembly and the counterweight on opposite sides of the traction sheave. An adjustment mechanism enables the second elevator car to be adjusted in relation to the first elevator car within the car assembly. The adjustment mechanism has an adjustment device, a first adjustment traction device and a second adjustment traction device. The first adjustment traction device and the second adjustment traction device are guided over the adjustment device. The first adjustment traction device and the second adjustment traction device are connected to the second elevator car on one side of the adjustment device and to the counterweight on the other side.

An elevator system with an elevator car arrangement has a safety device. The elevator car arrangement includes an upper elevator car, a lower elevator car and an elevator car frame, in which frame the elevator cars can be moved in opposite directions. The safety device has an upper instantaneous safety gear for the upper elevator car and a lower instantaneous safety gear for the lower elevator car. The upper instantaneous safety gear includes a remotely tripping unit that can be tripped by the lower elevator car. Furthermore, the lower instantaneous safety gear includes a remotely tripping unit which can be tripped by the upper elevator car.

An unlocking device with an actuator releases a safety cover of a maintenance opening for opening. The locking device has a safety circuit for actuating the actuator. The safety circuit includes at least one first switching contact and a second switching contact arranged in series, wherein the actuator in a closed state of the first and the second switching contacts is connected by the safety circuit with a power source, and the first switching contact can be switched by a control unit. One or more of the unlocking device can be used in an elevator system.

An elevator system (20) is provided including a hoistway (22) and an elevator car (24) movable within the hoistway (22) between a plurality of landings (26). The elevator car (24) includes at least one air scoop (70) configured to fluidly couple an interior of the elevator car (24) to the hoistway (22) such that a controlled fluid flow may pass there between. The hoistway (22) may or may not include a ventilation opening (50) configured to couple the hoistway (22) to an air source disposed outside of the hoistway (22).

An elevator car is constructed and arranged to move along a hoistway defined by a stationary structure. The elevator car includes a cabin and a component constructed and arranged to be in motion with respect to the cabin. A generator is carried by the cabin and is mechanically coupled to the component for driving the generator as the elevator car moves along the hoistway. An energy storage device of the elevator car is carried by the cabin and is configured to be charged by the generator. An electrical load of the elevator car is powered by at least one of the energy storage device and the generator.
