Abstract

Nel bastone sfollagente secondo l'invenzione sono ridotti il rumore da vibrazioni o le deviazioni, anche dopo uso ripetuto, ed il rischio di disaccoppiamento degli elementi sotto la forza di spinta per l'estensione del suo corpo principale, seppure lo spessore di parete è ridotto, per ridurne il peso. Una pluralità di elementi tubolari cilindrici sono tra loro accoppiati a scorrimento telescopico, di guisa che una superficie ad andamento conico all'estremità di punta di un elemento tubolare cilindrico esterno ed una superficie ad andamento conico all'estremità posteriore di un elemento tubolare cilindrico interno sono tra loro impegnate per prevenire il disaccoppiamento all'atto dell'estensione. Delle superfici di guida di scorrimento cilindriche circonferenziali, coassiali rispetto all'asse degli elementi tubolari, sono provviste davanti e dietro dette superfici ad andamento conico e gli elementi tubolari cilindrici sono disposti in contatto scorrevole superficie contro superficie, prevenendo rumore o deviazioni. Inoltre, lo spessore di parete all'estremità di punta dell'elemento tubolare cilindrico esterno è maggiorato per prevenire il disaccoppiamento.In the trolling stick according to the invention, noise from vibrations or deviations are reduced, even after repeated use, and the risk of decoupling of the elements under the thrust force for the extension of its main body, even if the wall thickness is reduced , to reduce its weight. A plurality of cylindrical tubular elements are coupled to each other by telescopic sliding, in such a way that a conical surface at the tip end of an external cylindrical tubular element and a conical surface at the rear end of an internal cylindrical tubular element are committed to prevent decoupling upon extension. Circumferential cylindrical sliding guide surfaces, coaxial with respect to the axis of the tubular elements, are provided in front and behind said tapered surfaces and the cylindrical tubular elements are arranged in sliding contact surface against surface, preventing noise or deviations. Furthermore, the wall thickness at the tip end of the external cylindrical tubular element is increased to prevent decoupling.
