AI Technical Summary

Benefits of technology

The solution provides improved visibility and safety by effectively removing stubborn debris, including insects, dirt, and tree sap, while minimizing the need for manual cleaning and extending the operational life of wiper blades through durable materials and design.

Problems solved by technology

However, even with today's windshield wipers, ice, dirt, insects and other debris can collect on the windshield despite the sweeping action of the windshield wiper, obscuring the driver's view.
Additionally, although some modern windshield wipers take advantage of aerodynamics in order to maintain contact between the windshield surface and the wiper blades, they do not take advantage of the wind available at moderate to high vehicle speeds to assist in the distribution of cleaning fluids and the removal of liquids from the windshield surface.

Embodiment Construction

[0022] The preferred embodiments of the invention will now be described with reference to the attached drawing figures. FIG. 1 shows a cross section of a frame 100 according to an embodiment of the invention. The frame is formed with two channels 102 in the bottom adapted to engage longitudinally disposed squeegees 104 (not shown). The frame as shown also has a third channel 106 between the first two channels adapted to engage a longitudinal brush 108. FIG. 2 is a perspective view of the frame without the squeegees or brush. Frame 100 is preferably made of plastic, rubber, nylon, ABS, or any other suitable material. Frame 100 also preferably has a uniform cross section, advantageously enabling the frame to be manufactured using an extrusion process. Those of skill in the art will readily appreciate that any material capable of being formed into a frame is considered to be within the scope of the present invention, and plastic, nylon and the like are merely exemplary materials. Alumi...

Abstract

An improved windshield wiper is described having a pair of squeegees and a brush disposed between said squeegees. The single-piece molded frame of the wiper includes openings along the frame back that are adapted to create a vacuum when the vehicle is moving. The brush spine is preferably perforated such that fluid is drawn from the windshield, into the brush bristles and out through the brush spine perforations and openings, when air passing over the wiper causes a vacuum between said squeegees.

Description

PRIORITY CLAIM [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 899,017, filed Jul. 27, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 463,412, filed on Jun. 18, 2003 (now U.S. Pat. No. 6,799,349), the entire contents of each of said applications being hereby incorporated by reference.FIELD OF THE INVENTION [0002] The present insertion relates to motor vehicle windshield wipers. In particular, the present invention relates to windshield wipers that incorporate brushes. BACKGROUND OF THE INVENTION [0003] Windshield wipers are an important safety feature in automobiles, trucks, buses, trains, and any other vehicle that includes an windshield and is subject to rain, snow, ice, insects, tree sap, dirt, mud, and the like. Windshield wipers typically include a longitudinal frame and one or more flexible squeegees running along the length of the frame. The frame is usually held by a motorized arm that sweeps the wiper across the...
