Abstract:
1. A control lever device for vehicles, comprising: a support structure with means for connecting the device to a handlebar; a cylinder-piston unit connected to the support structure; a lever pivotally connected to the support structure by means of a pivot pin and adapted to rotate about said pivot pin along an angular actuation stroke extending from an angular rest position of the lever in a first direction of rotation, said lever being further adapted to rotate about said pivot pin along an angular collapse stroke extending from said angular rest position in a second direction of rotation, opposite the first direction; a transmission portion arranged between the lever and the cylinder-piston unit in a manner to transmit the movement of the lever along the angular actuation stroke to the piston of the cylinder-piston unit; wherein the transmission portion is arranged relative to the lever such that, when the lever is in the angular actuation stroke, the lever abuts against the trans-mission portion and when the lever is in the angular collapse stroke, it is separated from the transmission portion; wherein the transmission portion comprises a first end in permanent contact with a piston of the piston-cylinder unit and a second end which abuts against a seat of the lever, when the lever is in the angular actuation stroke; and further comprising an elastic gasket engaging the support structure and the transmission portion for holding the transmission portion against the piston in a preset position when the lever is in the angular collapse stroke, disengaged from the transmission portion; guide means to facilitate the proper mutual positioning of the seat of the lever and the second end of the transmission portion, when the lever shifts from the angular collapse stroke to the rest position, and elastic means acting between the support structure and the lever such as to hold the lever elastically in the rest position.
