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: A structure for frame pieces of a pneumatic vacuum elevator is disclosed. The structure includes at least two horizontal arc pieces 30 and at least two vertical pieces 40 including a first arc end and a second arc end. Each of the first arc end and the second arc end include an angled cut profile. Each of the first arc end and the second arc end are adapted to receive a first coupling piece 100 at the angled cut profile. The first coupling piece 100 includes at least two holes 110. The at least two holes 110 are adapted to mechanically couple the at least two horizontal arc pieces 30 with the respective at least two vertical pieces 40 using a screw-fixing mechanism, upon receiving the respective at least two vertical pieces 40 at the angled cut profile. The at least two holes 110 are positioned at a first predefined position on the first coupling piece 100.

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 locking device for a guide rail is disclosed. The device includes a first edge including a plurality of teeth shaped projections. The first edge compresses and locks a first surface of a covering sheet placed on a base ring. The device also includes a second edge opposing the first edge. The second edge includes a V-shaped groove, wherein the second edge is disposed to hold at least one furrow of the guide rail for interlocking. The first edge and the second edge of the locking device locks air gap between the covering sheet, the guide rail connecting one or more surfaces of the base ring and a vertical pillar coupled to the guide rail.
