Claim:
A pivoting support assembly with a locking device for an awning arm, of the type comprising: a fixed support ( 10 ); a pivoting body ( 20 ) articulately supported on said fixed support ( 10 ) such that it can perform a pivoting movement about a pivot axis parallel to that of a winding roller of a canvas of the awning between a retracted position and a service position; an arm ( 30 ) articulately supported on said pivoting body ( 20 ) such that it can rotate between a folded position and an extended position; an adjustable stop ( 40 ) for limiting said pivoting movement of the pivoting body ( 20 ), thus determining the degree of inclination of the awning in said service position; and locking means linked to the movement of the arm ( 30 ) for locking the pivoting body ( 20 ) in its service position when the arm is in its extended position, said locking means comprising a locking member ( 50 ) movable between an inactive position, in which said locking member ( 50 ) does not interfere with said adjustable stop ( 40 ), and a locking position, in which the locking member ( 50 ) locks the adjustable stop ( 40 ) with respect to the pivoting body ( 20 ) when the latter is in its service position, the adjustable stop ( 40 ) has a circumferential groove ( 43 ) and a grip element ( 44 ) configured to be gripped by a rotating driving tool to adjust the position thereof, and thus said degree of inclination of the awning; said locking member ( 50 ), when it is in its locking position, is inserted into said circumferential groove ( 43 ) of the adjustable stop ( 40 ) such that said grip element ( 44 ) is accessible and the adjustable stop ( 40 ) can be rotated but cannot be axially moved with respect to the pivoting body ( 20 ); said adjustable stop ( 40 ) comprises a rod ( 41 ) connected to the fixed support ( 10 ) such that it can pivot about a stationary pin ( 60 ) parallel to said pivot axis and slidingly passed through a transverse hole ( 71 ) formed in a mobile pin ( 70 ) rotatably installed in a housing ( 21 ) of the pivoting body ( 20 ), and a stop head ( 42 ) connected to said rod on one side of said mobile pin ( 70 ) opposite said stationary pin ( 60 ); said stop head ( 42 ) is housed in a bell mouth ( 72 ) of said hole ( 71 ) formed in said mobile pin ( 70 ) when the pivoting body ( 20 ) is in the service position; and the circumferential groove ( 43 ) of the stop head ( 42 ) is aligned with an axial hole ( 73 ) formed in said mobile pin ( 70 ) when the stop head ( 42 ) is housed in said bell mouth ( 72 ), characterized in that said locking member ( 50 ) comprises a retaining portion ( 51 ) housed such that it can slide along said axial hole ( 73 ) of the mobile pin ( 70 ) between the inactive position, in which said retaining portion ( 51 ) is removed from the circumferential groove ( 43 ) of the adjustable stop ( 40 ), and the locking position, in which said retaining portion ( 51 ) is inserted into the circumferential groove ( 43 ) of the adjustable stop ( 40 ).
