Abstract
A windshield wiper comprises a pressure-applying superstructure and a squeegee assembly releasably mounted on the superstructure to permit replacement of the squeegee when worn. Releasable retaining means comprise a projection on one of the superstructure yokes adjacent to an endmost pair of the claws thereof that retain the squeegee assembly and a cooperating recess on the backing member of the squeegee assembly. The retaining means thus uses the flexibility of the backing member to provide the necessary retention. The projection may have a ramp shape to facilitate the latching action as the squeegee assembly is mounted. The invention is applied to a wiper structure for winter conditions in which the superstructure and backing member are completely enclosed by a thin flexible enclosure against the entry of ice and snow, the retaining means being surrounded by an integral shroud that serves as an end closure for the respective end of the flexible enclosure, such a construction requiring also a separate shrouded end clip of comparable structure to the retaining means to close the other end of the flexible enclosure.
