Latest Patents
Yamamoto's latest patents include a latch device and a device for controlling the opening and closing of doors. The latch device is designed to accurately control the opening and closing of a door. It features an opening/closing switch lever that shifts between a retreated position and an advanced position. When a striker is positioned in an engagement groove of a latch, the switch lever remains in the retreated position. Conversely, when the striker is removed, the lever shifts to the advanced position. This mechanism ensures precise control over the door's operation.
The second patent, a door latch apparatus, is engineered to close a vehicle door effectively. It operates by shifting the striker and latch from a first engagement state to a second engagement state through the action of an output lever driven by an actuator. If the shift is restricted, the output lever can still perform a retracting operation, ensuring the door remains secure.
