Seal assembly for a pneumatic vacuum elevator

A seal assembly for a pneumatic vacuum elevator, comprising:

• an elevator cabin structural sealing plate adapted to fit over a top portion of a cylindrical elevator cabin,
• characterised by:
• a top plate configured to house adjoining elevator cabin structural sealing plate components with mechanical and adhesive coupling, wherein the top plate is fabricated in circular shape to fit over the top surface of the cylindrical elevator cabin;
• a seal cover outer plate mechanically coupled along edges of the top plate, wherein the seal cover outer plate is configured to provide a covering to the elevator cabin structural sealing plate from sideways,
• a plurality of U-shaped corner plates fabricated at outer circumference of the seal cover outer plate at predefined positions, wherein the plurality of U-shaped corner plates is adapted to receive at least one guide rail thereby enabling upward and downward movement of the cylindrical elevator cabin via the guiding rails in predefined path;
• a set of reinforcement bars mechanically coupled to bottom surface of the top plate in lateral plane and inner circumference of the seal cover outer plate, wherein the set of reinforcement bars together form a predefined shape comprising a plurality of u shaped inward depressions corresponding to the plurality of U-shaped corner plates thereby supporting the plurality of U-shaped corner plates, the seal cover outer plate and the top plate;
• at least one bumper and liner plates affixed over outer circumference of the seal cover outer plates and press against inner wall of elevator cylinder, wherein the bumper and liner plates comprise outward protrusion which remain constantly in touch with inner wall of elevator cylinder thereby sealing the cylindrical elevator cabin and reducing vibrations during upward and downward movement.
