Abstract: The present approaches are in the in the field of vacuum (or pneumatic) elevators, where the elevator cabin is brought into motion in a vertically situated or vertically inclined and hermetically sealed elevator shaft by means of aerial pressure differential above and below the elevator cabin. Such approaches do not require having any ropes, pulleys, chains, gears, or hydraulics that are traditionally used in conventional elevator systems. More specifically, the present approaches are in the field of panoramic vacuum elevators, where the elevator hoistway is built of panoramic glass panels running from floor to ceiling of every floor and the elevator cabin is built of panoramic glass panels running from floor to the ceiling of the cabin, and that this type of elevator does not incorporate any metal constructive structures—frames, mesh, guides or rails that are traditionally used in every conventional elevator product.

Abstract: A suspension arrangement 10 to absorb stress acting on an elevator cabin 20 during landing is provided. The suspension arrangement includes the elevator cabin to move bidirectionally through an external cylinder 30 to transport passengers between levels of a structure. The suspension arrangement includes a landing lever 40 to project towards the external cylinder when the elevator cabin reaches a floor level. The suspension arrangement includes a landing bar 50 to slide downwards over the pillar 60 corresponding to a motion of the landing lever upon establishing a contact with the landing lever projected towards the external cylinder. The suspension arrangement includes a guide pin 70 meshed with the landing bar and housed in a base ring 80 associated with the external cylinder. The guide pin is to compress a spring 90 encircling the guide pin corresponding to the motion of the landing bar.

Abstract: A guide rail-pillar system is disclosed. The system includes at least one guide rail pillar to guide an actuation of a cabin of a pneumatic vacuum elevator, wherein the at least one guide rail pillar is disposed at an external cylinder assembly. The at least one guide rail pillar includes a first surface. A curved structure is extruded from a first surface of the at least one guide rail pillar, wherein the curved structure enables movement of the cabin in a vertical direction. The at least one guide rail pillar includes at least two grooves disposed on lateral sides. The at least two grooves accommodates a covering sheet for enclosing the external cylinder assembly. The at least one guide rail pillar includes at least three ribs. The at least three ribs connects the at least one guide rail pillar with a base ring and the external cylinder assembly.

Abstract: An elevator cabin seal for an elevator is described. The elevator cabin seal includes a plate having a plate interior surface, a seal member, and a plurality of adjustment members. The seal member has a seal member interior surface and a seal member top surface contiguous with the seal member interior surface. The seal member top surface is coupled to the plate interior surface. Each adjustment member of the plurality of adjustment members is coupled to the plate interior surface and contacts the seal member interior surface to exert an adjustable force against the seal member interior surface.

Abstract: A pneumatic flow controlling device is disclosed. The device includes a perforated component disposed on a bottom component coupled to a top surface of a pneumatic vacuum elevator. The perforated component includes multiple perforations to enable air circulation from outside to inside of the elevator cylinder. The device also includes a diaphragm component to expand and compress based on the air circulation. The device also includes a primary valve to allow an air supply to the elevator cylinder for controlling movement of an elevator cabin within a tubular pathway based on a control signal received from an elevator controller. The device also includes a secondary valve to allow the air supply to the elevator cylinder for dynamically varying speed of the elevator cabin at one or more landing positions.

Abstract: A pressurized fluid powered cabin-management system for an elevator system with a cabin and drive system is provided. The cabin-management system is configured to direct operation of the elevator system upon arrival of one of the cabins at a floor, and comprises a floor detector configured to detect when the cabin is located at a floor and to activate a timer. The timer is configured, when triggered, to activate a timing arrangement and to pass pressurized fluid to a control valve being in a first position. The timing arrangement is configured to direct the control valve to assume a second position after a predetermined amount of time. The cabin-management system performs, when pressurized fluid is passed to the control valve in its first position, actions for opening a door, and, after the control valve has assumed its second position, actions for travel of the cabin.

Abstract: A pneumatic vertical transportation device comprises an expandable cylinder, a carriage rack, an air piping controller, and an air exhauster. The expandable cylinder includes a bellow body, with one end hanging carriage rack and the other end connected with a fixing plate. The expandable cylinder is connected with the air piping controller. While the carriage rack is rising, the air exhauster draws air from the bellow body through the air piping controller to gradually decrease pressure inside. Once pressure difference exceeds weight of the carriage rack, the carriage rack begins to rise. Volume of the expandable cylinder is reduced such that the lower disc of the expandable cylinder approaches top, and the expandable cylinder is maintained at low pressure state. While the carriage rack is descending, air is fed into the expandable cylinder through the air piping controller to gradually expand the bellow body, letting the carriage rack descend.
