Abstract
A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.
Claims16
A wiper, comprising:
- a carrier enclosing a hollow passage, said carrier including:
- a pair of blade supports extending in generally parallel relation along a longitudinal length of said carrier;
- a pair of blades correspondingly disposed in said pair of blade supports;
- a plurality of outlets which communicates between said hollow passage and a location on the external surface of said carrier, said plurality of outlets periodically located between said pair of blade supports along said longitudinal length of said carrier;
- a first end piece coupled to a first end of said carrier and a second end piece coupled to a second end of said carrier;
- a fluid source configured to contain an amount of fluid, said fluid source fluidically coupled to said hollow passage in said carrier;
- a fluid flow generator fluidically coupled to said fluid source capable of generating a flow of said amount of fluid between said fluid source and said plurality of outlets of said carrier;
- and
- a vacuum generator capable of generating a vacuum at said plurality of outlets to collect said amount of fluid.
A wiper, comprising:
- a carrier enclosing a hollow passage, said carrier including:
- a pair of blade supports extending in generally parallel relation along a longitudinal length of said carrier;
- a pair of blades correspondingly disposed in said pair of blade supports;
- and
- an airfoil to distribute air flow about the carrier in manner which directs aerodynamic forces through the carrier to said pair of blades.
A wiper, comprising:
- a carrier enclosing a hollow passage, said carrier including:
- a pair of blade supports extending in generally parallel relation along a longitudinal length of said carrier;
- a pair of blades correspondingly disposed in said pair of blade supports;
- wherein said carrier comprise a resilient flexible material having a resiliently flexible curvature between a first carrier end and a second carrier end to allow the sweeping surface said pair of blades to flexibly conform in wiping engagement with a wipeable surface in response to forcible urging upon a central portion of said carrier.
