Patent number: 10625714Abstract: Base end sides of washer tubes 44, 45 are arranged in an axial direction of a swinging shaft PS at one end portion of an arm head 40, and they are drawn out from a head side pipe housing portion 41a so as to curve toward a side opposite to a shaft fixing portion 42 side. Each of the washer tubes 44, 45 is wound around the shaft fixing portion 42 during swinging of the arm head 40 without applying any load to the swinging shaft PS. No tension acts on each of the washer tubes 44, 45, and each of the washer tubes 44, 45 is not rubbed against the shaft fixing portion 42. Therefore, deterioration of the washer tubes 44, 45 can be suppressed. When the washer tubes 44, 45 are wound around the shaft fixing portion 42, a periphery of the shaft fixing portion 42 is suppressed from swelling outward in a radial direction thereof. This makes it possible to prevent the arm head 40 around the swinging shaft PS from increasing in size.Type: GrantFiled: March 23, 2016Date of Patent: April 21, 2020Assignees: MITSUBA CORPORATION, HONDA MOTOR CO., LTDInventors: Masayuki Shimoyama, Tomoya Nishikawa, Atsuhiro Kuwabara, Yutaka Yamashita, Shin Fujiwara, Hideyuki Koizumi, Takeshi Sasaki, Taisuke Goto, Tatsuya Ohmaru, Yuki Takahashi

Patent number: 10625715Abstract: injection positions (A2, B2, and C2) toward which washer liquids (W) are injected from the forward-side injection nozzles (A1, B1, and C1) and injection positions (D2 and E2) which washer liquids (W) are injected from the backward-side injection nozzles (D1 and E1) are alternatively shifted in the longitudinal direction of the blade rubber. Therefore, in wiping-out motion of the blade rubber for one reciprocation, the front glass (12) can uniformly get wet, the total number of injection nozzles can be made less than ever, the consumption amount of washer liquid (W) at the time of reciprocating wiping-out motion of the blade rubber can be reduced, power consumption of the washer pump can be reduced, and the size of the washer pump can be decreased.Type: GrantFiled: December 18, 2014Date of Patent: April 21, 2020Assignees: Mitsuba Corporation, Honda Motor Co., Ltd.Inventors: Masayuki Shimoyama, Masayuki Arima, Masaya Yonaga, Takeshi Sasaki, Tatsuya Ohmaru, Taisuke Goto

Patent number: 10507803Abstract: A nozzle unit 34 which jets washer fluid toward a windshield is fixed to an arm piece 33 whose front end side is fitted to a hook fixing member 23e. As a result, the nozzle unit 34 can be fixed without using the fitting member adopted in the conventional case, and located closer to the hook fixing member 23e. This reduces a positional shift of the nozzle unit 34 relative to the wiper blade 20 to the minimum, thus stabilizing the injection-target locations of washer fluid on the windshield.Type: GrantFiled: May 27, 2015Date of Patent: December 17, 2019Assignees: Mitsuba Corporation, Honda Motor Co., Ltd.Inventors: Masayuki Shimoyama, Masayuki Arima, Masaya Yonaga, Takeshi Sasaki, Tatsuya Ohmaru, Taisuke Goto

Patent number: 10005434Abstract: A wiper apparatus is improved in wiping performance, and can suppress a disturbance due to cleaning liquid in a driver's field of view. Each cleaning liquid W1 and W2 is jetted from four forward-side injection nozzles and four backward-side injection nozzles in a direction opposite to the wiper blade 20, and toward injection-target locations, and a distance between the wiper blade 20 and an injection-target location for cleaning liquid W1 and W2 on the opposite side from a center of a swinging motion of the wiper blade 20 in a wiping direction of the wiper blade 20 is larger than a distance between the wiper blade 20 and an injection-target location for cleaning liquid W1 and W2 on the same side as the center of the swinging motion of the wiper blade in the wiping direction of the wiper blade 20.Type: GrantFiled: October 20, 2016Date of Patent: June 26, 2018Assignees: Mitsuba Corporation, Honda Motor Co., Ltd.Inventors: Masayuki Shimoyama, Masayuki Arima, Daisuke Kobayashi, Takeshi Sasaki, Tatsuya Ohmaru, Taisuke Goto

Patent number: 9963121Abstract: A wiper blade includes a blade rubber and a rubber holder. In the rubber holder, a water channel through which a washing liquid flows along a longitudinal direction is provided. In the rubber holder, an injection port that communicates with the water channel and is configured to be opened by water pressure and inject the washing liquid is provided. The injection port is formed into a slit shape, and a plurality of injection ports are provided in the longitudinal direction. A width of the injection ports varies along the longitudinal direction, and the injection port closer to an outer end side has a larger slit width. A larger amount of the washing liquid is injected from the injection port having a larger slit width, and the injection amount of the washing liquid becomes larger toward the outer end side at which more washing liquid is required.Type: GrantFiled: November 28, 2012Date of Patent: May 8, 2018Assignee: MITSUBA CORPORATIONInventors: Masayuki Shimoyama, Satoshi Ishikura, Masayuki Arima, Daisuke Kobayashi
