Method and arrangement to close a bubble top for a chairlift

Abstract

A method to close a bubble top ( 1 ) for a chairlift having a bubble top ( 1 ) that has two final position whereby one first position corresponds to the open position and whereby the other second position corresponds to the closed position. The bubble top ( 1 ) is driven to a third partially closed position ( 20 ) lying between the first and second position during departure of the chair from a station whereby the handle ( 5 ) to be actuated by the user ( 2 ) to close the bubble top ( 1 ) is moved essentially in front of the user's main body axis so that the user ( 2 ) may close the bubble top ( 1 ) from a more favorable position, physically.

1 . A method to close a bubble top ( 1 ) for a chairlift having a bubble top ( 1 ) that has two final positions ( 10 ,  30 ) whereby one first position corresponds to the open position ( 10 ) and whereby the other second position corresponds to the closed position ( 30 ), characterized in that said bubble top ( 1 ) is driven to a third partially closed position ( 20 ) lying between the first and second position during departure from a station, whereby the handle ( 5 ) to be actuated by the user ( 2 ) to close said bubble top ( 1 ) is moved essentially in front of said user's main body axis so that said user ( 2 ) may close said bubble top ( 1 ) from a more favorable position, physically.  
     
     
         2 . An arrangement to execute the method according to  claim 1 , wherein an actuation device ( 8 ,  42 ) is provided on said bubble top ( 1 ) whereby one end ( 7 ) of said actuation device is hinged to said bubble top  1 , and wherein said actuation device cooperates with a forcing guide ( 41 ) provided in a station to rotate said bubble top ( 1 ) from the open position ( 10 ) to the partially closed position ( 20 ).  
     
     
         3 . An arrangement according to  claim 2 , wherein the forcing guide is a slanted rail ( 41 ) so that said bubble top ( 1 ) closes continuously up to a stop in the partially closed position ( 20 ).  
     
     
         4 . An arrangement according to  claim 3 , wherein during empty running of the chairs, there is provided a second rail with a different inclination in place of said rail ( 41 ) with which the actuation device ( 8 ) continuously closes said bubble top ( 1 ) up to the closed position ( 30 ).  
     
     
         5 . An arrangement according to  claim 3 , wherein the inclination of said rail ( 41 ) may be changed during empty running of chairs so that the actuation device ( 8 ) continuously closes said bubble top ( 1 ) up to the closed position ( 30 ).
