Abstract
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° 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 the carrier and lower edge of the window. When the cable then pulls in the other direction on the pulley, it positively screws the window carrier inwardly horizontally before lowering the window carrier to open the window.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
202 words
A reciprocating driving mechanism for vertically and horizontally moving the lower edge of a window in a housing, comprising: (1) a substantially vertical tract in said housing having a vertical guiding slot ending at its upper end into bifurcated cam slots, (2) a carrier for the lower edge of said window comprising a horizontal movable portion attached to said edge of said window and a rotary portion connected by a helical cam means to said horizontal portion, whereby oscillation of said rotary portion reciprocates horizontally said horizontal portion, said rotary portion having a pulley means and a pair of diametrically spaced pins guided in said vertical guiding slot and in and out of said bifurcated cam slots for oscillating said rotary portion, (3) cable means attached to said pulley means of said rotary portion for vertically reciprocating said carrier along said tract in said vertical cam guiding slot and oscillating said rotary portion guided by said pins in said bifurcated slots, (4) drum means for winding and unwinding said cable means, and (5) means for reversibly rotating said drum means; whereby when said window is closed, its lower edge moves outwardly to be more flush with the outside surface of said housing.
Claim 2
Dependent Claim
202 words
A reciprocating driving mechanism for vertically and horizontally moving the lower edge of a window in a housing, comprising: (1) a substantially vertical tract in said housing having a vertical guiding slot ending at its upper end into bifurcated cam slots, (2) a carrier for the lower edge of said window comprising a horizontal movable portion attached to said edge of said window and a rotary portion connected by a helical cam means to said horizontal portion, whereby oscillation of said rotary portion reciprocates horizontally said horizontal portion, said rotary portion having a pulley means and a pair of diametrically spaced pins guided in said vertical guiding slot and in and out of said bifurcated cam slots for oscillating said rotary portion, (3) cable means attached to said pulley means of said rotary portion for vertically reciprocating said carrier along said tract in said vertical cam guiding slot and oscillating said rotary portion guided by said pins in said bifurcated slots, (4) drum means for winding and unwinding said cable means, and (5) means for reversibly rotating said drum means; whereby when said window is closed, its lower edge moves outwardly to be more flush with the outside surface of said housing.
Claim 3
Dependent Claim
25 words
A reciprocating driving mechanism according to claim 1 wherein said horizontal movable portion of said carrier comprises a pin movable in said helical cam means.
Claim 4
Dependent Claim
21 words
A reciprocating driving mechanism according to claim 1 wherein opposite ends of said cable means are anchored in said pulley means.
Claim 5
Dependent Claim
25 words
A reciprocating driving mechanism according to claim 1 wherein said means for reversibly rotating said drum means comprises a reversible electric motor and gear mechanism.
Claim 6
Dependent Claim
163 words
A flush vehicle window regulator comprising: (1) a substantially vertical track having a vertical slot bifurcated at its upper end, (2) a carrier for the lower edge of said window, (3) a pulley means oscillatable about a horizontal axis journalled in said carrier and connected thereto by a helical cam means for horizontally reciprocating said carrier when said pulley means is oscillated, said pulley means having a pair of diametrically spaced pins guided in said slot and for rotating said pulley when said pins are in said bifurcated portion of said slot, (4) linear flexible means attached to said pulley for reciprocating said carrier along said vertical track and oscillating said pulley means, (5) drum means for winding and unwinding said linear flexible means, and (6) means for reversibly rotating said drum means whereby said window is opened and closed and when in its closed position its lower edge is moved outwardly to be more flush with the outside surface of said vehicle.
