Support device for video/photographic equipment
A support device ( 1; 100 ) for video/photographic equipment comprising at least one telescopic rod ( 2; 101 ) comprising: —a first tubular portion ( 10 ); —a second tubular portion ( 11 ) received inside the first tubular portion so as to be able to slide axially; —a third tubular portion ( 12 ) received inside the second tubular portion so as to be able to slide axially; —a first locking mechanism ( 14 ) arranged between said first tubular portion and the second tubular portion in order to lock the relative position of said first and second tubular portion in a desired position; —a second locking mechanism ( 20 ) arranged between said second tubular portion and the third tubular portion in order to lock the relative position of the second and the third tubular portion in a desired position.
1. Support device ( 1 ; 100 ) for at least one of video or photographic equipment, comprising at least one telescopic rod ( 2 ; 101 ) that can be moved between an extended position and a retracted position, said telescopic rod comprising:
a first tubular portion ( 10 );
a second tubular portion ( 11 ) received inside said first tubular portion ( 10 ) so as to be able to slide axially;
a third tubular portion ( 12 ) received inside said second tubular portion ( 11 ) so as to be able to slide axially;
a first locking mechanism ( 14 ) arranged between said first tubular portion ( 10 ) and said second tubular portion ( 11 ) in order to lock a relative position of said second tubular portion with respect to said first tubular portion in a desired position;
a second locking mechanism ( 20 ) arranged between said second tubular portion ( 11 ) and said third tubular portion ( 12 ) in order to lock a relative position of said third tubular portion with respect to said second tubular portion in a desired position;
a connecting element ( 30 ) that receives and extends between said first and said second locking mechanisms ( 14 , 20 ) and is fastened to the first and second locking mechanisms such that, by actuating said connecting element ( 30 ), said first and second locking mechanisms ( 14 , 20 ) are simultaneously actuated in order to lock or unlock the axial sliding sliding of said first, second and third tubular portions ( 10 , 11 , 12 );
wherein said connecting element ( 30 ) comprises a sleeve ( 31 ) that extends externally around said first and second locking mechanisms ( 14 , 20 ).
2. Support device according to claim 1 , wherein each of said first and second locking mechanisms ( 14 , 20 ) is actuated by a rotation about an axis (X) of said second tubular portion ( 12 ), and said connecting element ( 30 ) is constrained in rotation to said first and to said second locking mechanism ( 14 , 20 ) so as to be able to slide axially with respect to at least one of said first or second locking mechanisms ( 14 , 20 ).
3. Support device according to claim 1 , wherein said sleeve ( 31 ) is integral with one of said first or second locking mechanisms ( 14 , 20 ).
4. Support device according to claim 3 , wherein at least one groove ( 34 , 35 ), which extends axially, is provided in one of said sleeve ( 31 ) or said first or second locking mechanisms ( 14 , 20 ), and at least one radial projection ( 32 , 33 ) is provided on the other of said sleeve ( 31 ) or said first or second locking mechanisms ( 14 , 20 ), wherein said projection engaged in said at least one groove, preventing a relative rotation of said sleeve ( 31 ) and said first or second locking mechanism ( 14 , 20 ) and, at the same time, allowing said sleeve ( 31 ) to slide axially with respect to said first or second locking mechanism ( 14 , 20 ).
