Shroud

Abstract

A shroud comprises a frame having a main opening delimited by a main wall and at least one secondary opening delimited by a secondary opening, for the passage of a cooling air flow; a ventilator mounting system associated with the frame to support the ventilator at the main opening; a panel for closing the secondary opening, connected to the frame and movable, by rotation, between a lowered position and a raised position; the shroud comprises a pin, defining the axis of rotation of the panel, extending through the secondary opening and having a first and a second end respectively connected to a first and a second section of the secondary wall, opposite each other, a pair of hooks being provided in the panel for connection to the pin.

1 . A shroud comprising
 a frame with a main opening delimited by a main wall and at least one secondary opening, delimited by a secondary wall, for the passage of a cooling air flow,   a ventilator mounting system associated with the frame to support the ventilator at the main opening,   a panel for closing the secondary opening, connected to the frame and movable, by rotation, between a lowered position and a raised position,   hinge means which operate between the frame and the panel to allow rotation of the panel between the raised and lowered positions, the hinge means being defined by first engagement means associated with the frame and second engagement means associated with the panel,   the shroud wherein the first engagement means comprise a pin which defines the axis of rotation of the hinge means, which extends through the secondary opening and which has a first and a second end respectively connected to a first and a second section of the secondary wall, opposite each other, the second engagement means being connectable to the pin.   
     
     
         2 . The shroud according to  claim 1 , wherein the pin is substantially straight. 
     
     
         3 . The shroud according to  claim 1 , wherein the pin is substantially horizontal. 
     
     
         4 . The shroud according to  claim 1 , wherein the frame and the pin are made as a single part. 
     
     
         5 . The shroud according to  claim 1 , wherein the secondary wall comprises an upper edge, a lower edge and a first and second lateral edges, the first and second lateral edges connecting the upper edge to the lower edge, the secondary pin being substantially rectangular and the pin extending between the first and second lateral edges. 
     
     
         6 . The shroud according to  claim 5 , wherein the pin has a first end integral with the first lateral edge and a second end integral with the second lateral edge. 
     
     
         7 . The shroud according to  claim 1 , wherein the second engagement means comprise a first and a second hook integral with the panel and located on the panel in such a way as to engage the pin substantially at a first and a second end of the pin. 
     
     
         8 . The shroud according to  claim 1 , wherein the main wall is substantially cylindrical in shape, the mounting system comprising
 a ventilator mounting ring located in the main opening and coaxial with the main wall,   a plurality of arms which extend from the main wall to the mounting ring to support the mounting ring and the ventilator.
