20080301897 | Windshield Wiper - A windshield wiper for an automotive vehicle having an elongated base and an elongated flexible blade extending outwardly in a first direction from the base. The blade has a free edge adapted to contact a windshield on an automotive vehicle. An elongated scraper also extends outwardly from the base at an acute angle relative to the blade so that a free edge of the scraper is spaced from and generally parallel to the free edge of the blade. The scraper is constructed of a material more rigid than the blade to remove adhered debris from the windshield upon transverse movement of the windshield wiper. | 12-11-2008 |
20090056050 | MULTIPLE BLADE WINDSHIELD WIPER - A windshield wiper blade assembly has a blade arm to which a blade subassembly is pivotally coupled. The blade subassembly includes a first blade, a second blade, and a third blade located side-by-side. The first and third blades are formed of a scrubbing material for debris and the second blade is formed of a rubber-like material. Movement in a first direction causes engagement with the windshield to exert a force that pivots the blade subassembly into a first position in which the first and second blades contact the windshield and the third blade is spaced from the windshield. Movement in an opposite second direction causes engagement with the windshield to exert another force which pivots the blade subassembly into a second position in which the second and third blades are in contact with the windshield and the first blade is spaced from the windshield. | 03-05-2009 |
20100218331 | WIPER HAVING TILTING MULTI-BLADE - Disclosed herein is a wiper having a tilting multi-blade to wipe a windshield of a transportation means. The wiper includes a wiper arm, a reciprocating tilting device, a blade holder, a multi-blade and a blade compressing plate. The wiper arm has a tilting control stopper. The reciprocating tilting device has a tilting angle control hole into which the tilting control stopper is inserted such that the reciprocating tilting device is rotatable within a limited angular range. The blade holder is coupled to the reciprocating tilting device and has holder compressing plate springs. The blade holder has an elastic notch to provide uniform elastic repulsive force. The multi-blade includes a coupling part which is inserted into the blade holder, and multiple blade lips which are symmetrically provided on left and right sides. The blade compressing plate is inserted into the blade holder and has plate springs to evenly compress the multi-blade. | 09-02-2010 |
20110232022 | STRUCTURE AND METHOD OF MANUFACTURING A UNITARY DOUBLE-BLADE WIND SHIELD WIPER - The present invention relates a structure and method of manufacturing a unitary double-blade wind shield wiper. The method comprises a thermal forming step, a cutting step, a folding step and preferably a bonding step. In the thermal forming step, a rubber plate is imprinted into a rubber product which contains a plurality of continually connected wind shield wipers with a plurality of folding guide grooves. In the cutting step, the rubber product is divided into a plurality of independent wind shield wipers, wherein each of the independent wind shield wipers has a pair of blades extending in opposite directions to each other. In the folding step, each of the independent wind shield wipers is folded along the folding guide groove thereby to make the pair of blades parallel to each other. Preferable, further to impose the bonding step to fix the independent wind shield wipers into a permanent configuration, so as to be a more durable unitary double-blade wind shield wiper. | 09-29-2011 |
20120198647 | WIPER BLADE - A wiper blade includes a first blade and a second blade surrounding the first blade, such that the first blade is not exposed for use, wherein the removal of the second blade exposes the first blade for use. In another embodiment, a wiper blade includes a body, an inner blade attached to the body, an outer blade bonded to the body or inner blade, a gripping mechanism attached to the outer blade and a removal mechanism located between the inner blade and outer blade, wherein the removal mechanism is attached to the gripping mechanism. | 08-09-2012 |
20120291217 | Windshield Wiper Blade and Suited for Removal of Solid Material - A wiper blade device with a durable mesh sponge member attached between two removable wiper blade members. The combination sponge and wiper blade construction provides a unitary device that combines the two distinct functions of cleaning solids and wiping water from vehicular windshields. The device further provides minimal windshield obstruction given its construction, improving current wiper blade capabilities without degrading visibility or impacting safety of the vehicle. The device may comprise a wiper blade refill attachable to a wiper blade mount, providing the practitioner with an improved windshield wiper blade that is cost effective and one that requires no modification of the vehicle to implement. | 11-22-2012 |
20140359962 | WINDSHIELD WIPER/SCRAPER - A windshield wiper apparatus comprising a frame, a flexible wiper element and at least one scraper element expanding the length of the frame. | 12-11-2014 |
