Device for hooking the visor to a motorcyclist helmet cap

Abstract

A device for removably hooking visor ( 2 ) to a cap ( 4 ) of the type provided, in correspondence of each side end of porthole ( 22 ) of the helmet, with a guide-body ( 5 ) for the rotation of the visor that engages according to an axis into a hole ( 23 ) of the visor. The device also comprises a cursor ( 7 ) slidingly associated to the guide-body and provided with means ( 8 ) for holding the visor. Cursor ( 7 ) translates between an engagement position of the holding means with the visor and a disengagement position. The device is also provided with elastic means ( 25 ) to push the holding means to an engagement position with the visor.

         6 . The device according to any of the preceding claims, characterized in that said elastic means comprise a helical spring ( 25 ) interposed between cursor ( 7 ) and guide-body ( 5 ).  
     
     
         7 . The device according to any of the preceding claims  2 - 6 , characterized in that said tooth ( 9 ) is obtained integrally with said cursor ( 7 ) and said elastic means ( 25 ) that push cursor ( 7 ) to an engagement position with visor ( 2 ), also push said tooth ( 9 ) in one of the said one or more seats ( 10 ) obtained in visor ( 2 ).  
     
     
         8 . The device according to any of the preceding claims  2 - 7 , characterized in that said tooth ( 9 ) and said one or more seats ( 10 ) have a complementary tapered saw-tooth profile.  
     
     
         9 . The device according to any of the preceding claims, characterized in that said holding means comprise a fork ( 12 ) whose upper arm ( 13 ) superposes to part of visor ( 2 ) to lock it axially when cursor ( 7 ) is in said engagement position.  
     
     
         10 . The device according to  claim 9 , characterized in that said tooth ( 9 ) is realized between arms ( 13 ,  14 ) of said fork ( 12 ).  
     
     
         11 . The device according to  claim 9  or  10 , characterized in that the lower arm ( 14 ) of said fork ( 12 ) engages in an aperture ( 16 ) obtained in guide-body ( 5 ) suitable to define the end-of-stroke positions of said cursor ( 7 ).  
     
     
         12 . The device according to any of the preceding claims, characterized in that said guide-body ( 5 ) comprises at least a contrast protrusion ( 18 ) to prevent visor ( 2 ) from shifting along said axis.  
     
     
         13 . The device according to any of the preceding claims, characterized in that said guide-body ( 5 ) is realized disjointedly with respect to cap ( 3 ) of helmet ( 4 ).
