Abstract
The lock device for locking a striker pin is shown, which comprises a base plate to which a latch plate is pivotally connected. The latch plate is formed with a latching notch. The latch plate can assume a full-latch position wherein the latching notch fully latches the striker pin, a half-latch position wherein the latching notch incompletely latches the striker pin and a release position wherein the latching notch fully releases the striker pin. A first spring is used for biasing the latch plate to pivot toward the release position. A locking plate is pivotally connected to the base plate and has a pawl portion which is engageable with the latch plate to provide the latch plate with the full-latch and half-latch positions. A second spring is used for biasing the locking plate to pivot in a direction to achieve the engagement between the pawl portion and the latch plate. A full open lever is pivotally connected to the base plate. A lost-motion mechanism is arranged between the locking plate and the full open lever so that when, with the latch plate assuming the half-latch position, the full open lever is pivoted beyond a given degree, the pawl portion of the locking plate is disengaged from the latch plate thereby to permit the latch plate to assume the release position.
