Abstract
The disclosure concerns a regulator for moving a window in a vehicle door ccessively substantially vertically and horizontally and vice versa. In other words, once the window is closed vertically the lower edge may be moved outwardly horizontally to become more flush with the outside surface of the door of the vehicle. The regulator comprises a closed loop of cable wrapped about a reversible driving drum and having a vertical reach which is attached to a pulley connected to the carrier for the window. This pulley is provided with a pair of diametrically opposite cam follower pins or rollers that are guided in a vertical slot parallel to the vertical reach of cable, which slot has a bifurcated or Y-shaped pair of slots at its upper end for rotating the pulley up to about 180.degree. when the pulley reaches the "Y" and the cable means continues to pull. The pulley also has a helical groove axial and integral therewith for positively screwing the carrier attached to the lower edge of the window outwardly horizontally. This carrier has a socket with a radial pin therein fitting into said helical groove so that oscillation of said pulley produces the horizontal reciprocating motion of t…
