Abstract
A multi-blade ice removing windshield wiper assembly has a support frame carrying an axially rotatable elongate body having three radially extending spacedly arrayed windshield engaging blades. A toothed blade having a plurality of teeth scores accumulated frost and ice on a windshield while windshield wiper arm moves in a first direction. Spacedly adjacent shaving blade clears away the scored frost and ice from the windshield as the windshield wiper arm moves in the second opposite direction. Third flexible wiper blade removes rain and water from the windshield and may be selectively engaged when the frost and ice removing blades are not needed. Locking mechanism positionally secures the elongate body within the support frame to prevent unwanted axial rotation of the body within the support frame.
Claims12
A vehicle windshield wiper blade assembly for removing liquid, ice and frost from a vehicle windshield as a windshield wiper arm moves in a first direction and in an opposing second direction across the windshield comprising in combination:
- a frame having a first end portion and a second end portion supporting an axially rotatable elongate body;
- the body having a pivot axle at a first end portion communicating with the frame and a pivot axle at a second end portion communicating with the frame and carrying three spaced apart parallel windshield engaging blades extending generally radially from the body;
- a locking means to prevent undesired axial rotation of the body relative to the frame;
- and
- a biasing spring carried on one pivot axle between an end portion of the body and the frame to positionally bias the body to engage with the locking means.
