Patent number: 10436414Abstract: In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.Type: GrantFiled: November 6, 2015Date of Patent: October 8, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Kazuyuki Yokoyama, Masatsugu Ohashi, Masahiro Arai

Publication number: 20170371235Abstract: A projection mechanism of a vehicle projection device projects a graphic of a graphic film toward an outer side of a vehicle. A projection direction of the graphic from the projection mechanism is inclined with respect to a rotation axis of the projection mechanism. Thus, by manually rotating a dial to rotate the projection mechanism about the rotation axis, the projection direction of the graphic from the projection mechanism can be altered, and the projection position of the graphic from the projection mechanism can be altered.Type: ApplicationFiled: December 17, 2015Publication date: December 28, 2017Inventors: Kazuyuki YOKOYAMA, Masatsugu OHASHI, Masahiro ARAI

Publication number: 20170368985Abstract: A vehicle projection device projects a graphic of a film body housed in a housing toward an outer side of the housing. It is possible to detach the film body toward an exterior of the housing via a communication hole in the housing by gripping a grip portion of the film body. This thereby enables the film body to be detached toward the exterior of the housing.Type: ApplicationFiled: December 17, 2015Publication date: December 28, 2017Inventors: Kazuyuki YOKOYAMA, Masatsugu OHASHI, Masahiro ARAI

Publication number: 20170349088Abstract: In a vehicle door mirror device, a projection device projects a graphic from a graphic film. The projection device is inserted into a cap in a state in which a holding tube of the cap has been inserted into a through hole in a visor, and the holding tube is held between a peripheral face of the through hole and a protrusion portion of the projection device. The projection device is thus installed at the visor in a manner retained by the cap alone. This thereby enables easy installation of the projection device to the visor.Type: ApplicationFiled: December 17, 2015Publication date: December 7, 2017Inventors: Kazuyuki YOKOYAMA, Masatsugu OHASHI, Masahiro ARAI

Patent number: 8690363Abstract: In a vehicle door mirror device, a base is attached to a door and covered with a base cover. A gasket is disposed on a door panel of the base cover, a seal portion of the gasket seals a gap between a lower side end of the base cover and the door panel. The seal portion is extended from the gasket toward the base cover side. Therefore, even if a dimension of the gap between the lower side end of the base cover and the door panel varies, the lower side end of the seal portion can be suppressed from being separated from an outer periphery of the base cover toward the inner side, the base cover can be suppressed from looking floating from the door panel, and appearance of the gap between the lower side end of the base cover and the door panel can be improved.Type: GrantFiled: December 28, 2011Date of Patent: April 8, 2014Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Takehiro Hamada, Masami Kato, Masatsugu Ohashi, Masao Ayabe, Yasunori Hirosawa

Patent number: 8651673Abstract: Efficiently suppressing chatter of a mirror face of a mirror. In a vehicle door mirror device, a case is disposed at a back face side of a mirror, a substrate unit is accommodated in the case, gap between the mirror and the case is sealed by sealing agent, thereby sealing the substrate unit. The holder, the case and the sealing agent are integrated together. A press contact tab is integrally provided to a housing box of the holder such that the press contact tab makes press contact with an anti-vibration pillar. The supporting rigidity to the mirror at the position of the substrate unit can accordingly be efficiently raised, vibration of the mirror due to the substrate unit can be efficiently suppressed, and chatter of a mirror face of the mirror can be efficiently suppressed.Type: GrantFiled: January 9, 2012Date of Patent: February 18, 2014Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Masatsugu Ohashi, Takashi Ichikawa

Patent number: 8226064Abstract: A sliding torque between a pivot portion and a fitting portion may be preferably secured. In an inner mirror device, pivot portions are arranged on both end portions in an axis line direction of a stay formed by a resin material. One pivot portion is fitted in a fitting hole of a holder main body, and the other pivot portion is fitted in a fitting hole of a device main body. In this manner, the holder and the device main body are connected to each other through the stay. In this case, plural notches are formed in the pivot portions, and outside dimensions of the pivot portions may be elastically expanded and reduced. A metal spring pin is pressed into the stay, and the spring pin biases the pivots in a dimension-expansion direction.Type: GrantFiled: May 29, 2009Date of Patent: July 24, 2012Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventor: Masatsugu Ohashi

Patent number: 6637900Abstract: A mirror assembly for a vehicle includes a visor which houses a mirror main body (a mirror), a stay cover provided between the visor and the vehicle, and a base which is assembled so as to pass through the stay cover. In the present invention, in a state in which inclined surfaces formed at both the stay cover and the visor press-contact one another, the stay cover is nipped by the base and the visor. The stay cover is held by nipping force of the base and the visor such that the visor and the stay cover are assembled without gaps therebetween, without a need to separately prepare a fixing member of the stay cover.Type: GrantFiled: December 18, 2001Date of Patent: October 28, 2003Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventor: Masatsugu Ohashi

Patent number: 6447127Abstract: A spring having four urging legs is fixed in a stay of a mirror, and retention pawls corresponding to the urging legs are formed at a base fixed within a passenger compartment of a vehicle. The urging legs engage with the retention pawls so that the stay is held at the base at a predetermined load. Because the four urging legs are provided on the spring, an urging force of the respective urging legs can be made small and bending of the urging legs is unobstructed by other members. Accordingly, when a load of predetermined value or greater acts upon the mirror, the urging legs corresponding to the direction in which the load acts slide and the engagement between all of the urging legs and the retention pawls is released. The mirror is allowed to fall regardless of the direction in which the load acts.Type: GrantFiled: November 22, 2000Date of Patent: September 10, 2002Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Shigeki Yoshida, Masatsugu Ohashi, Kazuyuki Noda, Yoshihiro Fujikawa
