An object ( 2 ) mounted on wheels ( 4 ) has a grip device ( 1 ) of the type wherein a free end ( 10 ) of a telescopically extensible supporting structure ( 8 ) carries an integral grip portion ( 9 ) substantially parallel to an axis of rotation ( 6 ) of the wheels ( 4 ); according to the invention, the grip portion ( 9 ) has first ( 11 ) and second ( 12 ) articulating means enabling the grip portion ( 9 ) to rotate, with respect to the supporting structure ( 8 ), about two distinct axes of rotation ( 13, 14 ) perpendicular to each other; and angular locking means ( 33, 34 ) for preventing rotation of the grip portion ( 9 ) with respect to the supporting structure ( 8 ), and ensuring firm but reversible connection of the grip portion ( 9 ) to the supporting structure ( 8 ) in a predetermined mutual position. A third articulating means ( 35 ) enables the grip portion ( 9 ) to translate along one of the axes of rotation ( 13 ). |
