Anti-lift device for windshield wipers
First Claim
1. An anti-lift device for windshield wipers comprising;
- a base member,a series of fin members linearly disposed thereon and extending at an obtuse angle therefrom in substantially parallel relation,each of said fin members being formed of two sections comprising flat surfaces intersecting and extending at an obtuse angle relative to each other and outwardly from the line of intersection to form an obtuse dihedral shaped fin surface,a perpendicular reinforcing web interconnecting the rear of each of said fin members, at the base of the dihedral angle, and said base member to provide support and stability to said fin members, andmeans on said base member for releasably attaching said device to a windshield wiper arm.

Abstract
An anti-lift device for windshield wipers is disclosed having a novel construction. More particularly the anti-lift device comprises a linear series of generally rectangular fin members having a dihedral shape. Each dihedral shaped fin has a lower leading edge integral with a rectangular base member and projects upwardly and rearwardly therefrom to terminate at a trailing edge. A perpendicular reinforcing web adjoins the backside of the dihedral fin and the base member. The base member contains a central longitudinal slot and "L" shaped clip for releasably attaching the anti-life device to a conventional windshield wiper arm. When installed on a windshield wiper arm, the aerodynamic forces acting upon the device will press the wiper arm and blade firmly to the windshield to prevent the blade from acting as an airfoil and lifting from the surface of the windshield.
