Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
An apparatus for driving sliding panels, particularly horizontally sliding windows in an automobile, according to a predetermined operational sequence, said apparatus comprising: a rotatable crank; a movable plate rotatably driven about an axis by said crank, said movable plate having a radius and a plurality of concentric grooved sections having different average radii, all of which are smaller than said radius of said movable plate; a first pinion for each said panel, each said first pinion having an axle; partial cogs on said grooved sections forming alternate racks intermittently drivingly engagable with each said pinion; a panel support connected to each said panel; and a transmission cable connected to each said first pinion and drivingly engaging each said panel support; whereby rotation of said crank is transmitted through said movable plate, said pinion, said transmission cable, and said panel support to alternatively drive each said panel.
Claim 2
Independent Claim
146 words
An apparatus for driving sliding panels, particularly horizontally sliding windows in an automobile, according to a predetermined operational sequence, said apparatus comprising: a rotatable crank; a movable plate rotatably driven about an axis by said crank, said movable plate having a radius and a plurality of concentric grooved sections having different average radii, all of which are smaller than said radius of said movable plate; a first pinion for each said panel, each said first pinion having an axle; partial cogs on said grooved sections forming alternate racks intermittently drivingly engagable with each said pinion; a panel support connected to each said panel; and a transmission cable connected to each said first pinion and drivingly engaging each said panel support; whereby rotation of said crank is transmitted through said movable plate, said pinion, said transmission cable, and said panel support to alternatively drive each said panel.
Claim 3
Dependent Claim
65 words
The device recited in claim 1 wherein: each grooved section alternately defines at least one driving zone of each said pinion, said zone being of variable length separated by reset zones without cogs and of lesser widths formed by the circumferential overlap of two of said driving zones, each said pinion remaining blocked in rotation by said reset zones without interrupting movement of said plate.
Claim 4
Dependent Claim
46 words
The device recited in claim 1 including: a drum supported by the axle of the pinion and having a helicoidal neck; a pair of pulleys; the transmission cable being wound about the drum and the pair of pulleys and defining a triangular trajectory of constant length.
Claim 5
Dependent Claim
28 words
The device recited in claim 3 including: a fixed slide bar with a groove having a S-profile; and the panels include a plurality of rollers engaging the groove.
Claim 6
Dependent Claim
46 words
The device recited in claim 1 including: an auxiliary pinion mounted on the axle of the first pinion and wherein the transmission cable is made with an external helicoidal threading for engagement with the auxiliary pinion, the panel supports sliding on the sheath of the cable.
