<p>PURPOSE: To simplify the constitution of a lock by forming a fork clutch section for a door lock of an arm section, a prelocking section and a main locking section and conducting locking by a closed lock and a lock-closing pin capable of being displaced from the prelocking section to the main locking section at 180 deg.. CONSTITUTION: A fork clutch section 1 for the door lock is formed of an arm section 4, a prelocking section 5 and a main locking section 6, and a lock-closing pin 3 installed on a lock plate 2 can be rotated at the position of the main locking section 6. The arm section 4 is brought to an engaged state with the lock-closing pin at the position of the main locking section 6. Displacement to the place of lock opening is obstructed by a rotatable lock pawl 8 mounted on the plate 2 in the fork clutch 1. The lock-closing pin 3 can be displaced from a prelocking-section position 5 to a main locking position 6 at approximately 180 deg. in axis 11 eccentric in parallel with an axis 10. Accordingly, the constitution of the door lock is simplified, and manufacturing cost and operating cost can be reduced.</p> |
