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.

Claims (27)

1. A structure ( 10 ) for one or more frame pieces of a pneumatic vacuum elevator ( 20 ) comprising:

at least two horizontal arc pieces ( 30 ), wherein each of the at least two horizontal arc pieces ( 30 ) comprises a rectangular shape with at least one demi bullnose edge; and

at least two vertical pieces ( 40 ),

wherein each of the at least two horizontal arc pieces ( 30 ) comprises:

a first arc end ( 70 ); and

a second arc end ( 80 ),

wherein each of the first arc end ( 70 ) and the second arc end ( 80 ) comprises an angled cut profile ( 90 ),

wherein each of the first arc end ( 70 ) and the second arc end ( 80 ) are adapted to receive a first coupling piece ( 100 ) at the angled cut profile ( 90 ),

wherein the first coupling piece ( 100 ) comprises at least two holes ( 110 ) 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 ( 90 ),

wherein the at least two holes ( 110 ) are positioned at a first predefined position on the first coupling piece ( 100 ).

2. The structure ( 10 ) as claimed in claim 1 , wherein the at least two horizontal arc pieces ( 30 ) are manufactured by an aluminum die casting mechanism.

3. The structure ( 10 ) as claimed in claim 1 , wherein the at least two vertical pieces ( 40 ) are manufactured by an aluminum extrusion mechanism.

4. The structure ( 10 ) as claimed in claim 1 , wherein the at least two horizontal arc pieces ( 30 ) comprises an inner chamber ( 130 ), wherein the inner chamber ( 130 ) comprises at least one second coupling piece ( 140 ) comprising at least two holes ( 150 ) for mechanically coupling the at least two horizontal arc pieces ( 30 ) with a support piece ( 160 ) attached to the pneumatic vacuum elevator ( 20 ) using the screw-fixing mechanism.

5. The structure ( 10 ) as claimed in claim 1 , wherein each of the at least two vertical pieces ( 40 ) comprises a rectangular shape with at least one demi bullnose edge.

6. The structure ( 10 ) as claimed in claim 1 , wherein each of the at least two vertical pieces ( 40 ) comprises an inner surface ( 190 ) comprising at least two grooved rib profiles ( 200 ).

7. The structure ( 10 ) as claimed in claim 6 , wherein the at least two grooved rib profiles ( 200 ) are adapted to mechanically couple the at least two vertical pieces ( 40 ) with the respective at least two horizontal arc pieces ( 30 ) using the screw-fixing mechanism, upon placing a first vertical piece end ( 170 ) of the at least two vertical pieces ( 40 ) at the angled cut profile ( 90 ) of the respective at least two horizontal arc pieces ( 30 ).

8. The structure ( 10 ) as claimed in claim 6 , wherein the at least two grooved rib profiles ( 200 ) are positioned at a second predefined position on the inner surface ( 190 ), wherein the second predefined position is in correspondence with the first predefined position.

9. A pneumatic vacuum elevator ( 20 ) with a structure ( 10 ) for one or more frame pieces comprising:

an elevator cabin ( 45 ) adapted to carry a passenger for transiting across one or more floors of a building;

an external cylinder ( 220 ) positioned concentrically to the elevator cabin ( 45 ) externally, wherein the external cylinder ( 220 ) comprises an elevator door ( 210 ) adapted to allow entry and exit of the passenger corresponding to the elevator cabin ( 45 ); and

the structure ( 10 ) for the one or more frame pieces mechanically coupled to a covering sheet ( 60 ) of at least one of the elevator cabin ( 45 ) and the external cylinder ( 220 ), wherein the structure ( 10 ) comprises at least two horizontal arc pieces ( 30 ) and at least two vertical pieces ( 40 )), wherein each of the at least two horizontal arc pieces ( 30 ) comprises a rectangular shape with at least one demi bullnose edge, wherein each of the at least two horizontal arc pieces ( 30 ) comprises:

a first arc end ( 70 ); and

a second arc end ( 80 ),

wherein each of the first arc end ( 70 ) and the second arc end ( 80 ) comprises an angled cut profile ( 90 ),

wherein each of the first arc end ( 70 ) and the second arc end ( 80 ) are adapted to receive a first coupling piece ( 100 ) at the angled cut profile ( 90 ),

wherein the first coupling piece ( 100 ) comprises at least two holes ( 110 ) 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 ( 90 ),

wherein the at least two holes ( 110 ) are positioned at a first predefined position on the first coupling piece ( 100 ).
