Arrangement for water activities

Abstract

An arrangement for underwater activities comprises at least two spaces arranged one on the other thereby forming a multilayer structure, where at least one space is configured to be filled by the water for water activity. In addition the arrangement comprises a room for spectators. Each of said spaces comprises at least one wall and layer forming together said space. The first space comprises a first set of activity means for underwater activity, and the second space comprises a second set of activity means for activity. At least portion of said walls and/or layers are transparent. In addition the room for spectators is arranged in connection with said spaces and separated from the space by the wall and/or layer structure.

1 . An arrangement for underwater activities, wherein the arrangement comprises:
 at least two spaces arranged one on the other thereby forming a multilayer structure, where at least one space is configured to be filled by the water for water activity, and   a room for spectators,   
       wherein:
 each of said at least two spaces comprises at least one wall, and a layer forming together said space, and 
 at least a portion of said at least one wall and/or layer is transparent, and 
 
       wherein
 said room for spectators is arranged in connection with said at least two spaces and separated from the spaces by a wall and/or a layer structure, and 
 one of the at least two spaces comprises a first set of activity means for underwater activity, and 
 another of the at least two spaces comprises a second set of activity means for activity. 
 
     
     
         2 . The arrangement according to  claim 1 , wherein at least one space, advantageously lower space, is configured to be filled with water at least one space, advantageously upper space, is filled partially with water and/or one space, advantageously upmost space, is a dry space. 
     
     
         3 . The arrangement according to  claim 1 , wherein the arrangement comprises a container supporting said spaces, and wherein said spaces are arranged to be moved in a vertical direction in the container. 
     
     
         4 . The arrangement according to  claim 1 , wherein said spaces comprise opening(s) between them to allow objects to move between a first space to a second space. 
     
     
         5 . The arrangement according to  claim 1 , wherein at least one space comprises an inner wall structure configured to form a sub-space, where said sub-space is formed either between the outer and inner wall structures of said sub-space or where said inner wall structure is configured to form an inner-sub-space limited by said inner wall structure. 
     
     
         6 . The arrangement according to  claim 4 , wherein said sub-space/inner-sub-space comprises an opening at its lower portion to the water of the water filled space and limited in its upper portion by said layer between said first and second spaces. 
     
     
         7 . The arrangement according to  claim 5 , wherein said sub-space/inner-sub-space comprises a pressure providing means configured to provide pressure inside the sub-space essentially equal to the hydrostatic pressure at the same level due to the water depth of the water filled space and thereby to keep the water surface at the opening in a certain level and thereby provide an air-sub-space filled space. 
     
     
         8 . The arrangement according to  claim 5 , wherein said sub-space comprises underwater theatre or auditorium, bench row(s) for spectators, and wherein said bench row, roofs and/or walls are made of transparent material. 
     
     
         9 . The arrangement according to  claim 1 , wherein the arrangement comprises an air-lock-type means in the connection with at least one space, especially in connection with the sub-space of the first space for entering into the space via said air lock. 
     
     
         10 . The arrangement according to  claim 3 , wherein at least one of the walls of the container and/or spaces is transparent, or the walls comprise section that is transparent, for allowing observation of the activities taking place inside the reservoir from outside of the reservoir. 
     
     
         11 . The arrangement according to  claim 3 ,
 wherein the upper portion of the container comprises at least one open opening for entering to the container.   
     
     
         12 . The arrangement according to  claim 3 , wherein the arrangement comprises means for filling the container and/or the spaces with water, water removing means for removing water from the container and/or the spaces, means for removing air from the container or spaces, and means for feeding air to the container and/or spaces. 
     
     
         13 . The arrangement according to  claim 3 , wherein the arrangement comprises or wherein the arrangement is configured to function as a floating platform connected to the container and/or the spaces, and therefore supports the container and/or spaces and keeps the container and/or at least one space partially above surface level of the body of water, and wherein the floating platform provides also a room for spectators. 
     
     
         14 . The arrangement according to  claim 3 , wherein the arrangement comprises a room for spectators surrounded by and/or covered by the container and/or spaces. 
     
     
         15 . (canceled) 
     
     
         16 . The arrangement according to  claim 1 , wherein inside the at least one space there is provided a room for spectators. 
     
     
         17 . (canceled)
