Abstract

A structure 10 for constructing an improved guide pillar system of a pneumatic vacuum elevator is provided. The structure includes a column 20 . The column includes at least four sides including a first side 40 , a second side 50 , a third side 60 , and a fourth side 70 . The structure includes at least one angled section 80 to provide radius edges to the third side. The structure includes at least one channel section 90 including a first wall 100 to support a covering sheet 110 of the external cylinder. The first wall includes a first projection 120 including a gasket lining 130 to provide a vacuum tight sealing between the covering sheet and the first wall. The at least one channel section includes a second wall 140 to support a beading 150 to force the covering sheet against the first wall to prevent relative movements of the covering sheet.

Claims (28)

1 . A structure ( 10 ) for constructing an improved guide pillar system of a pneumatic vacuum elevator comprising:

a column ( 20 ) positioned in an external cylinder ( 30 ) of the pneumatic vacuum elevator, wherein the column ( 20 ) comprises at least four sides comprising a first side ( 40 ), a second side ( 50 ), a third side ( 60 ), and a fourth side ( 70 );

at least one angled section ( 80 ) positioned at a first predefined portion of each of the first side ( 40 ) and the second side ( 50 ), wherein the at least one angled section ( 80 ) is adapted to provide one or more radius edges to the third side ( 60 ) of the column ( 20 );

at least one channel section ( 90 ) positioned at a second predefined portion of each of the first side ( 40 ) and the second side ( 50 ), wherein each of the at least one channel section ( 90 ) comprises:

a first wall ( 100 ) adapted to support a covering sheet ( 110 ) of the external cylinder ( 30 ) of the pneumatic vacuum elevator, wherein the first wall ( 100 ) comprises a first projection ( 120 ) comprising a gasket lining ( 130 ) adapted to provide a vacuum tight sealing between the covering sheet ( 110 ) and the first wall ( 100 ); and

a second wall ( 140 ) adapted to support a beading ( 150 ) adapted to force the covering sheet ( 110 ) against the first wall ( 100 ) to prevent one or more relative movements of the covering sheet ( 110 ) with respect to the first wall ( 100 ), thereby forming the structure ( 10 ) for constructing the improved guide pillar system,

wherein the second wall ( 140 ) comprises a second projection ( 170 ) adapted to interlock with a slot ( 180 ) provided on the beading ( 150 ) to restrict the one or more relative movements of the beading ( 150 ) with respect to the second wall ( 140 ).

2 . The structure ( 10 ) as claimed in claim 1 , wherein the covering sheet ( 110 ) comprises one or more inclined slits ( 160 ) adapted to interlock with the first projection ( 120 ) to restrict the one or more relative movement of the covering sheet ( 110 ) with respect to the first wall ( 100 ).

3 . The structure ( 10 ) as claimed in claim 1 , wherein the first projection ( 120 ) is forming an obtuse angle with the first wall ( 100 ).

4 . The structure ( 10 ) as claimed in claim 1 , wherein the second projection ( 170 ) is forming an acute angle with the second wall ( 140 ).

5 . The structure ( 10 ) as claimed in claim 1 , wherein the beading ( 150 ) comprises one or more saw tooth slits ( 190 ) adapted to displace laterally upon forcing the covering sheet ( 110 ) against the first wall ( 100 ) to restrict the one or more relative movements of the covering sheet ( 110 ) with respect to the beading ( 150 ).

6 . The structure ( 10 ) as claimed in claim 1 , wherein the fourth side ( 70 ) comprises a guide rail ( 200 ) located at an outer surface of the fourth side ( 70 ), wherein the guide rail ( 200 ) is adapted to:

support an elevator cabin ( 210 ) via one or more coupling components; and

guide the elevator cabin ( 210 ) during a bidirectional movement of the elevator cabin ( 210 ).

7 . The structure ( 10 ) as claimed in claim 1 , wherein the covering sheet ( 110 ) comprises a polycarbonate sheet.

8 . The structure ( 10 ) as claimed in claim 1 , wherein the gasket lining ( 130 ) is composed of at least one of a material comprising graphite, rubber, teflon, compressed non asbestos fiber, and poly tetra fluoro ethylene.

9 . The structure ( 10 ) as claimed in claim 1 , wherein the beading ( 150 ) comprises at least one of a material comprising rubber, plastic, and silicone.

10 . A pneumatic vacuum elevator ( 300 ) comprising:

an external cylinder ( 30 ) comprising an elevator cabin ( 210 ) inserted therein, wherein the external cylinder ( 30 ) comprises a plurality of cylinders coupled using a base ring ( 310 ) and a band ring ( 320 );

a column ( 20 ) positioned in the external cylinder ( 30 ), wherein the column ( 20 ) comprises at least four sides comprising a first side ( 40 ), a second side ( 50 ), a third side ( 60 ), and a fourth side ( 70 );

at least one angled section ( 80 ) positioned at a first predefined portion of each of the first side ( 40 ) and the second side ( 50 ), wherein the at least one angled section ( 80 ) is adapted to provide one or more radius edges to the third side ( 60 ) of the column ( 20 );

at least one channel section ( 90 ) positioned at a second predefined portion of each of the first side ( 40 ) and the second side ( 50 ), wherein each of the at least one channel section ( 90 ) comprises:

a first wall ( 100 ) adapted to support a covering sheet ( 110 ) of the external cylinder ( 30 ) of the pneumatic vacuum elevator, wherein the first wall ( 100 ) comprises a first projection ( 120 ) comprising a gasket lining ( 130 ) adapted to provide a vacuum tight sealing between the covering sheet ( 110 ) and the first wall ( 100 );

a second wall ( 140 ) adapted to support a beading ( 150 ) adapted to force the covering sheet ( 110 ) against the first wall ( 100 ) to prevent one or more relative movements of the covering sheet ( 110 ) with respect to the first wall ( 100 ),

wherein the second wall ( 140 ) comprises a second projection ( 170 ) adapted to interlock with a slot ( 180 ) provided on the beading ( 150 ) to restrict the one or more relative movements of the beading ( 150 ) with respect to the second wall ( 140 );

a guide rail ( 200 ) positioned adjacent to the second wall ( 140 ) and mechanically coupled to the elevator cabin ( 210 ), wherein the guide rail ( 200 ) is disposed at the fourth side ( 70 ), wherein the guide rail ( 200 ) is configured to guide an actuation of the elevator cabin ( 210 ); and

a seal assembly ( 330 ) adapted to fit over a top portion of the elevator cabin ( 210 ), wherein the seal assembly ( 330 ) is configured to seal the elevator cabin ( 210 ) to reduce vibrations during upward and downward movement of the elevator cabin ( 210 ),

wherein the seal assembly ( 330 ) comprises a depressurizing system configured to prevent the elevator cabin ( 210 ) from coming into force contact with the external cylinder ( 30 ) during upward movement and contribute to safety of an elevator operation.
