Publication number: 20170203716Abstract: A steering lock device is for use with a steering shaft and includes a lock mechanism that includes a lock bar, a housing that includes an opening and accommodates the lock mechanism, a cover that closes the opening of the housing, and one or more protective walls arranged on the cover. The lock bar locks the steering shaft when the lock bar is moved to an engagement position where the lock bar is engaged with the steering shaft. The one or more protective walls are located in one or more imaginary unauthorized access routes to the lock mechanism extending from outside the steering lock device.Type: ApplicationFiled: December 27, 2016Publication date: July 20, 2017Inventors: Tomonori KAWACHI, Tomonori KIMURA, Shigeru WASHINO

Publication number: 20160023633Abstract: A steering lock device includes a lock body attached to a column post that rotatably supports a steering shaft, a locking bar to lock or unlock a rotation of the steering shaft by a rotating operation of a key cylinder unit housed in the lock body, a lock stopper to allow movement of the locking bar to a lock position or an unlock position, a locking lever to hold the locking bar at the lock position, and a camshaft to convert a rotary motion of the key cylinder unit into a linear motion of the lock stopper. The lock body includes a landing portion with which the lock stopper contacts so as to prevent the lock stopper from contacting with the camshaft in a lock operation that the locking bar is moved to the lock position.Type: ApplicationFiled: July 13, 2015Publication date: January 28, 2016Inventors: Hiroshi YOSHIDA, Takumi TAMEZANE, Tomonori KAWACHI

Patent number: 5632167Abstract: When a key cylinder is caused to come off a body, a regulating lever moves. As a result of such movement, a block member moves to engage with an engagement groove of an engagement body, so that the rotation of a cam shaft can be blocked. In addition, a lock piece enters between the block member and a cover. Even if the regulating lever is broken, the rotation of the cam shaft is blocked by the block member, and even if one attempts to move the block member in a disengagement direction, the movement of the block member is blocked by the lock piece.Type: GrantFiled: October 3, 1995Date of Patent: May 27, 1997Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Tomonori Kawachi, Nobuyoshi Yasuhara

Patent number: 5271252Abstract: The present invention relates to a steering shaft locking device in which a locking member is normally urged towards a lock position by a spring member, and is moved to a release position by the cam protrusion of a cam member when a key rotor is turned to an operating position. A key response member operates in such a manner that, when the locking member is moved to the release position with the key response member moved in a first direction upon insertion of the key into the key rotor, its end portion engages with the engaging portion of the locking member to hold the locking member at the release position, and that, when the key response member is moved in a second opposite direction upon extraction of the key from the key rotor, the end portion disengages the engaging portion, thus allowing the movement of the locking member to the lock position.Type: GrantFiled: November 8, 1991Date of Patent: December 21, 1993Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Nobuyoshi Yasuhara, Tomonori Kawachi

Patent number: 5050411Abstract: In a shift lever locking device for an automatic transmission of column type, a drive cam is turned with a key rotor mounted on a steering column, a shift shaft arranged along the steering column is turned by operating a shift lever so that the automatic transmission is shifted to a plurality of positions, a lock part is formed on the shift shaft, a link mechanism provided movably has at least a lever which is swung to operate in a link mode a drive part confronting with the driving cam of the key rotor and a lock member confronting with the lock part of the shift shaft; and an adjusting mechanism is provided for the lever of the link mechanism to adjust the positional relationships between the driving cam and the drive part and between the lock part and the lock member, whereby the assembling errors are absorbed which may be involved in assembling work.Type: GrantFiled: June 25, 1990Date of Patent: September 24, 1991Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Tomonori Kawachi, Minoru Morikawa, Noriyuki Suzuki, Masami Watanabe, Nobuyoshi Yasuhara, Yoshitaka Sato

Patent number: 4972692Abstract: A key-operated ignition device which prevents an engine starter from being driven while the engine is already running, so to protect the starter and engine from damage. The device comprises a key-operated rotor disposed in the device for turning a locking cam via a coupling plate to shift an ignition switch between off, on and start positions. A sliding member is selectively movable between first and second positions by a restriction plate, wherein when the sliding member is in the first position the rotor may be turned from the on position to the start position and when the member is in the second position, the rotor is prevented from again turning from the on position to the start position, without first turning to the off position. The restriction plate also prevents the rotor from being directly turned from the off position to a lock position.Type: GrantFiled: November 1, 1989Date of Patent: November 27, 1990Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Minoru Morikawa, Tomonori Kawachi
