Patent number: 8819995Abstract: A window regulator and a jig to facilitate assembly. The window regulator includes a drum configured to be able to rotate in a normal direction/reverse direction, an annular wire 71 partly wound around a drum, guide members 81, 83, 91 and 93 configured to guide the wire 71 in such a manner that the wire 71 is arranged along a direction of upward and downward movement of a window glass 53, slack preventing means configured to urge the wire 71 in a stretching direction and eliminate the slack of the wire 71, and window glass mounting means 101 and 103 configured to mount the window glass 53 to a portion of the wire 71 extending along the direction of upward and downward movement of the window glass 53, and a bracket 131 being mounted rotatably on the inner panel and having the guide member 83, and being configured to guide the guide member 83 to a mounting position on the inner panel is provided.Type: GrantFiled: December 13, 2006Date of Patent: September 2, 2014Assignees: Shiroki Kogyo Co., Ltd., Toyota Jidosha KabushikiInventors: Kimihiro Kinoshita, Koji Kawamatsu

Patent number: 8209907Abstract: A window regulator includes a wire sag compensating mechanism. The wire sag compensating mechanism includes an outer tube arranged between the vicinity of a drum and at least one wire guide member allowing passage of a wire therethrough and fixed at an end on the side of the wire guide member to a member where the wire guide member may be provided. A tube holding portion may be provided on a member on which the drum is provided allowing movable engagement of the drum side of the outer tube and guiding the drum side of the outer tube in the axial direction of the outer tube. A spring may be provided for urging the drum side of the outer tube away from the drum. A disengagement restricting arrangement (e.g., projections and elongated holes) may be provided for restricting the outer tube from disengaging from the tube holding portion.Type: GrantFiled: May 25, 2007Date of Patent: July 3, 2012Assignees: Shiroki Kogyo Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Kimihiro Kinoshita, Kenichi Suzuki, Takanori Natsume, Katsuaki Maruyama, Koji Kawamatsu

Publication number: 20100031575Abstract: [Problem] A subject is to provide a window regulator and a jig which facilitate assembly. [Means for Resolution] A wind regulator includes a drum configured to be able to rotate in a normal direction/reverse direction, an annular wire 71 partly wound around a drum, guide members 81, 83, 91 and 93 configured to guide the wire 71 in such a manner that the wire 71 is arranged along a direction of upward and downward movement of a window glass 53, slack preventing means configured to urge the wire 71 in a stretching direction and eliminate the slack of the wire 71, and window glass mounting means 101 and 103 configured to mount the window glass 53 to a portion of the wire 71 extending along the direction of upward and downward movement of the window glass 53, and a bracket 131 being mounted rotatably on the inner panel and having the guide member 83, and being configured to guide the guide member 83 to a mounting position on the inner panel is provided.Type: ApplicationFiled: December 13, 2006Publication date: February 11, 2010Inventors: Kimihiro Kinoshita, Koji Kawamatsu

Patent number: 7547060Abstract: To a pair of link arms, portions of a fitting mechanism that can be engaged with each other in a vehicle width direction are formed. Further, hinge bases that hold both ends of the pair of link arms rotatably can fit together in the vehicle width direction. By this structure, when a load is applied onto a sliding door from the outside of the vehicle owing to a side collision or the like, and a force is applied onto the fitting mechanism and the pair of hinge bases in the vehicle width direction and in the vehicle vertical direction, the portions of the fitting mechanism and the pair of hinge bases fit together, and the movement of the link arms to the upper side in the vehicle vertical direction is regulated. Thereby, the pulling deformation of the sliding door to the inside of the vehicle body is suppressed.Type: GrantFiled: April 12, 2006Date of Patent: June 16, 2009Assignee: Toyota Jidosha Kabushiki KaishaInventors: Katsuaki Maruyama, Koji Kawamatsu, Yukio Matsuda, Yoshinori Hitomi
