A platform assembly includes a first platform module having an elongated front face, a second platform module having an elongated front face, and a locking member for locking the front faces of the first and second platform modules to each other. The locking member is movably mounted on the first platform module in a longitudinal direction of the front face thereof, and at least one of the locking member and the second platform includes a locking protrusion, and the other of the locking member and the second platform includes a locking slot, wherein the locking protrusion is received by the locking slot and protrudes from the front face of the first platform module. An edge of the locking protrusion is behind an edge of the locking slot when the locking member is moved in said longitudinal direction of the front face, thereby locking the platform modules to each other.

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.

A top extensible section and an operating method thereof, an elevator car assembly, and an elevator system. The top extensible section is installed above a top plate of the elevator car when in use. The top extensible section includes a top wall and a plurality of side walls, and has an unfolded state and a folded state; in the unfolded state, the top wall and the plurality of side walls of the top extensible section define an expansion space which communicates with an inner space of the elevator car to provide an additional top space; and in the folded state, the top wall of the top extensible section is lowered to be substantially flush with the top plate of the elevator car, and the plurality of side walls are folded to provide an operating space on the plurality of side walls.

An elevator cab protection system is provided. The system includes first and second panels and three clips. Each of the clips includes a lower leg portion and an upper leg portion. The first clip is coupled to the first panel by a fastener. The lower leg portion of the first clip and the first panel define a first downwardly opening slot. The second clip is coupled to the first panel by a fastener with the upper leg portion of the second clip located above the upper end of the first panel. The third clip is coupled to the second panel by a fastener. The lower leg portion of the third clip is configured to be inserted into the upwardly opening slot defined by the upper leg portion of the second clip and the wall of the elevator cab to support the second panel relative to the first panel.

An elevator system may include a plurality of cars that are disposed vertically one above another in a common shaft. The plurality of cars may be independently movable. Further, the plurality of cars may include evacuation devices that permit the passage of passengers from a car to be evacuated into an adjacent car that is disposed vertically above or below the car to be evacuated. In some cases, an evacuation device of an uppermost car of the plurality of cars includes an opening floor hatch, and an evacuation device of a lowermost car of the plurality of cars includes an opening roof hatch.

An elevator includes a car and a counterweight suspended on hoisting ropes which are driven by a drive machine. The counterweight has a first side facing the elevator car path and a second side opposite to the car path. The counterweight includes at least one connecting passage between the first and second side of the counterweight. With this solution, air pressure built between the car and the counterweight when passing in the elevator shaft is reduced and the travel comfort is improved.

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 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.

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.
