Publication number: 20220073034Abstract: A wiper structure for a resin window includes a wiper configured to wipe a part of a surface of the resin window. The wiper has an elastic wiper rubber and a wiper holder configured to hold the wiper rubber. The wiper rubber has a holding base portion, a lip portion, a body portion, and a neck portion. The lip portion is in contact with the resin window. In the lip portion, a ratio of a lip length in the direction toward the surface of the resin window to a lip thickness in the thickness direction is greater than 0 and less than or equal to 2.3.Type: ApplicationFiled: December 2, 2019Publication date: March 10, 2022Applicants: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI, DENSO CORPORATIONInventors: Yusuke SHIMA, Kenji TAKEMURA, Naoki TORN, Masami MURAMATSU

Patent number: 9517750Abstract: A wiper of a vehicle wiper device moves between a first position, which is a stop position, and a second position. A first pivot member is pivoted back and forth about a first axis by a drive force of a drive source. A second pivot member is pivotal about a second axis. A coupling pivot member is coupled to the first pivot member pivotally about a third axis and the second pivot member pivotally about a fourth axis. The wiper is coupled to and pivoted integrally with the coupling pivot member. A third position is located between the first position and the second position. A line extending through the third axis and the fourth axis is parallel to a line extending through the first axis and the second axis when the wiper is in a first movable range between the first position and the third position.Type: GrantFiled: August 1, 2013Date of Patent: December 13, 2016Assignee: ASMO CO., LTD.Inventor: Masami Muramatsu

Patent number: 8533898Abstract: A vehicle wiper device including a wiper arm, a wiper blade, and a wiping range enlarging mechanism is disclosed. The wiper arm is driven by driving force of a drive source. The wiper blade is coupled to a distal portion of the wiper arm at a constant position relative to the wiper arm. The wiper blade moves back and forth between first and second reversing positions while wiping a wiping surface of a vehicle body when the wiper arm is driven. The wiping range enlarging mechanism drives the wiper arm while moving a basal portion of the wiper arm so that a wiping angle of a basal portion of the wiper arm becomes greater than a wiping angle of a distal portion of the wiper arm at the second reversing position.Type: GrantFiled: December 17, 2009Date of Patent: September 17, 2013Assignee: ASMO Co., Ltd.Inventors: Hiroshi Matsumoto, Masahiko Yamanishi, Masami Muramatsu, Yuta Doi

Publication number: 20110292212Abstract: A washer nozzle removes foreign matter on an image capturing surface of a camera mounted to the outside of a vehicle by supplying washer fluid to the image capturing surface. The washer nozzle includes an inside spray hole and a discharge portion. The inside spray hole sprays the washer fluid introduced into the washer nozzle. The discharge portion receives washer fluid sprayed from the inside spray hole. The discharge portion has a passage extending in a direction intersecting the spray direction of the washer fluid and a discharge port connected to the passage. The discharge portion discharges, from the discharge port, washer fluid sprayed from the inside spray hole along the image capturing surface, while filling the passage with the washer fluid, thereby washing the image capturing surface.Type: ApplicationFiled: May 24, 2011Publication date: December 1, 2011Applicant: ASMO CO., LTD.Inventors: Takeshi Tanabe, Hiroshi Matsumoto, Masami Muramatsu

Patent number: 6658691Abstract: In a wiper arm, a head cover detachably attached to an arm head has a stopper wall that protrudes inward from an end thereof and is inserted into a gap between the arm head and an arm member. When the arm member is rotated by a certain angle to the arm head in the direction away from the windshield glass, the stopper wall comes in contact with the arm member so that further rotation of the arm member is suppressed. Accordingly, a possible damage of the wiper arm due to a car washer, which accidentally turns the arm member to the lock back state, is avoided. On the other hand, if a user detaches the head cover from the arm head, the arm member can be manually rotated to the lock back state so that a blade rubber replacement operation for a maintenance purpose is easy.Type: GrantFiled: March 29, 2002Date of Patent: December 9, 2003Assignee: Asmo Co., Ltd.Inventor: Masami Muramatsu

Patent number: 6594854Abstract: A wiper device has a center bore provided at a wiper blade, a supporting shaft disposed in the center bore and a connecting hole provided at a leading end portion of the wiper arm. The supporting shaft has first and second diameter portions at a circumference thereof and a diametric length of the second diameter portion is smaller than that of the first diameter portion The connecting hole is provided at a circumference thereof with an opening whose chord length is larger than the diametric length of the second portion but smaller than the diametric length of the first portion. The wiper blade may be attached to and detached from the wiper arm by making the second diameter portion correspond to the opening, but the wiper blade may not be detached from the wiper arm in a normal use of the wiper device by rotating the wiper blade relatively to the wiper arm till a position where the second diameter portion does not correspond to the opening in the connecting hole.Type: GrantFiled: March 16, 2000Date of Patent: July 22, 2003Assignee: Asmo Co., Ltd.Inventors: Hiroshi Matsumoto, Masami Muramatsu
