Patent number: 10961751Abstract: A vehicle door lock apparatus includes a housing, a fork, a pawl, a first lever displaceably provided in the housing such that the first lever can act on the pawl, and a second lever pivotably provided in the housing. One end of the second lever has a linkage coupled to a lower end of a transmission rod, which is coupled to an exterior door handle. The second lever pivots in response to an opening operation being performed on the exterior door handle and acts on the first lever. A plane of rotation contains an arcuate trajectory traced by the linkage when it pivots in response to the opening operation being performed, and is located farther in a frontward direction of a vehicle frame than a fixing surface. The plane of rotation is inclined relative to a plane containing the fixing surface, and intersects this plane in the vehicle downward direction.Type: GrantFiled: July 19, 2017Date of Patent: March 30, 2021Assignee: ANSEI CORPORATIONInventors: Masaharu Takagi, Satoshi Yamaji

Patent number: 10870371Abstract: An operation device (1) includes first bases (81A, 81B) and/or second bases (72A, 72B) that are elastically deformable in the direction of a pivot axis (X1) so that a shaft (120) can be inserted into a shaft hole (110). A first protrusion (121) is formed on a distal end portion of the shaft and projects radially outward from an outer sliding surface (120E). The first bases (81A, 81B) include a first escape section (111) recessed radially outward from an inner sliding surface (110E). The first escape section allows the first protrusion to pass through the first base when the shaft is being inserted into the shaft hole with an operation member (80) located in an initial position. A first slip-off preventing section (113) circumferentially adjacent to the first escape section prevents the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to an end position.Type: GrantFiled: December 19, 2018Date of Patent: December 22, 2020Assignee: ANSEI CORPORATIONInventors: Masaharu Takagi, Satoshi Umezu, Yukio Iwase

Patent number: 10458158Abstract: In a vehicle door lock apparatus, when disposed in an unlocking position, a second lever enables a fork to be displaced to an unlatched position and, in a locking position, it disables the fork from being displaced to the unlatched position. Third levers displace the second lever from the locking position to the unlocking position in response to an unlocking operation being performed on a lock operator and displace the second lever from the unlocking position to the locking position in response to a locking operation being performed on the lock operator. In an unblocking position, a fourth lever linked to the fork separates from the second lever. In a blocking position, the fourth lever contacts the second lever and blocks it from being displaced to the locking position. A fifth lever is linked with the fourth lever, detects the position of the fork, and disconnects or connects a switch.Type: GrantFiled: September 8, 2017Date of Patent: October 29, 2019Assignee: ANSEI CORPORATIONInventors: Masaharu Takagi, Satoshi Yamaji

Patent number: 8764077Abstract: A switching lever of a vehicle door lock device includes a lever main body, an inertial lever having a mass body pivotably disposed on the lever main body so as to be pivotable from its initial position about a pivot, and a torsion coil spring disposed between the lever main body and the inertial lever and biasing the inertial lever towards its initial position. If the inertial lever is disposed in its initial position and is displaced integrally with the lever main body, the inertial lever will press a pawl, thereby causing a fork to switch to an unlocked position. However, if an inertial force greater than a pre-determined value acts on the mass body, the inertial lever will pivot from its initial position in a direction opposite of the interial force and avoid pressing the pawl, such that the fork is maintained in a locked state.Type: GrantFiled: July 7, 2010Date of Patent: July 1, 2014Assignee: Ansei CorporationInventors: Masaharu Takagi, Satoshi Yamaji
