Abstract

Ensemble d'attelage réglable qui comprend un élément rail et une base. La base peut être fixée à l'élément rail, une partie de la base pouvant tourner par rapport à l'élément rail. Une pluralité de boules d'attelage peuvent s'étendre à partir de la base et une goupille peut être fixée pivotante à l'élément rail et à la base. Les boules d'attelage peuvent être mises en rotation de manière sélective par rapport à l'élément rail. Une partie de la base peut être mise en rotation pour faire basculer la position des boules d'attelage par rapport à l'élément rail.
