Latest Patents
Tokioka's latest patents include a sophisticated steering device that features a movable body capable of rotatably supporting a shaft member to which a steering member is attached. This device incorporates first and second rail mechanisms that guide the movement of the movable body in a front-rear direction. The first rail mechanism consists of a first rolling element row positioned between a first raceway face of a fixed rail and a second raceway face of a moving rail. Similarly, the second rail mechanism contains a second rolling element row situated between a third raceway face of a second fixed rail and a fourth raceway face of a second moving rail. Notably, the contact angles of the rolling elements differ between the two mechanisms, enhancing the device's functionality.
Another innovative steering device designed by Tokioka allows the steering member to be movable between an advanced position, where the driver can easily steer, and a retracted position closer to the front of the vehicle. This design includes a fixed member attached to the vehicle body and a movable member that holds the steering shaft. The upper and lower guide mechanisms linearly guide the movable member, ensuring smooth operation.
