Abstract

"MECHANISM MOTOR ROLLER AND DEVELOPER FOR TOYS AND SIMILARS", characterized in that it essentially comprises the set constituted by a fractional electric DC motor whose shaft engages through a mechanical reducing transmission with a motor part of a clutch that is axially displaceable on a fixed axis and whose part is subject to the action of elastic means that have a tendency to maintain it pressed against the other half of the clutch, that is against the driven part of the clutch itself and mounted on the axis itself coaxial with the first, with the particularity that, integral with the driven part of the clutch, there is, at least, a rotating pulley which has a flexible and roll-over element thereon, like a chain, one end of which is fixed to its hub while the other end of said flexible element is in a position to act on any organ desired action Onar through the rotation of the aforementioned pulley which has, laterally, projections that collaborate with a rotating exhaust wheel provided with teeth in most of which for its greater depth can adapt the above-mentioned outgoing to determine the partial turn of said escape wheel at each turn or fraction of the pulley until it reaches a shallow tooth of the exhaust wheel which acts as a limit switch for the successive turns of the pulley in the direction undertaken, without preventing the recoil in opposite direction of the turning movement of the pulley itself until another tooth of shallow depth is reached which will also act as opposite end of stroke, with which the pulley, in accordance with the direction of rotation given to the motor by means of a current inverter , will roll and unroll the flexible element of the pulley in either direction at will.
