Claim 6

A wiper device for a windshield of a motor vehicle or other vehicles, comprising a water collector fixedly mounted on the front side of the driver''s compartment of the vehicle; at least two wiper assembly mounting means vertically movably mounted on said water collector at two spaced apart locations thereon; said mounting means being vertically movable from a position below the lower edge of the windshield to a position substanTially coinciding with the lower edge of the windshield; a wiper assembly rotatably mounted on each of said mounting means for rotational movement across the windshield in frictional contact with the outer surface thereof defining circular loci and also for vertical movement with the mounting means, each of said wiper assemblies having an inoperative position in which the assembly is substantially horizontal and below the lower edge of the windshield; drive means for imparting rotation to said wiper assemblies; said drive means including means for providing one of said wiper assemblies a predetermined angle of delay with respect to the other wiper assembly and means for stopping the movement of said wiper assemblies in their horizontal position; and a lifting link mechanism for vertically moving said wiper assembly mounting means and wiper assemblies from their positions below the lower edge of the windshield to their positions substantially coinciding with the lower edge of the windshield.

Claim 7

The wiper device as set forth in claim 2, in which said water collector comprises a pair of spaced and parallel plate members having said opening defined therebetween.

Claim 8

The wiper device as set forth in claim 2, in which said wiper assembly mounting means comprises a pair of rotary shafts on which said wiper assemblies are mounted for rotational movement therewith; and a pair of hollow shaft holders for rotatably supporting said pair of rotary shafts.

Claim 9

The wiper device as set forth in claim 1, in which said wiper assemblies each comprises a wiper member and an integral elastic wiper element.

Claim 10

The wiper device as set forth in claim 5, in which said drive means comprises a pair of flexible shafts extending through said hollow shaft holders and each being connected to one end to each rotary shaft for rotatably driving the same; said first and second gears each being connected at one end to the other end to the other end of each flexible shaft for driving the same; and an electric motor connected to the other ends of said gears for driving the same.

Claim 11

A wiper device for a windshield of a motor-vehicle or other vehicles, comprising a water collector fixedly mounted on the front side of the driver''s compartment of the vehicle; wiper assembly mounting means vertically movably mounted on the water collector; wiper assemblies rotatably mounted on said mounting means for rotational movement across the windshield in frictional contact with the outer surface thereof defining circular loci and also for vertical movement with the mounting means; said wiper assemblied having operative and inoperative positions; drive means for rotatably driving said wiper assemblies; and a lifting link mechanism for vertically moving said wiper assembly mounting means and wiper assemblies between said operative and inoperative positions; and said lifting link mechanism comprising a motor; a lever rockably mounted on said motor; a pair of rods pivoted at one end to the opposite end of said lever; and a pair of bell cranks pivoted at one end to the other end of said rods and at the other end to a pair of vertically movable wiper shaft holders.
