Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a door lock device having a half latch position and a full latch position, for example, a door lock device for automobiles such as a twist-type side door, a sliding door, a back door, etc. The present invention relates to an automobile door lock device used for.

(Prior art) In conventional automobile door lock devices, when the door is closed by applying inertia to the door, the latch of the door lock device collides with the striker on the vehicle body, and the latch is incompletely engaged with the striker. The door is configured to close by moving beyond the half-latch position where the striker is engaged to the full-latch position where the striker is fully engaged. In addition, automobile doors generally have
Sealers/heels to prevent water leakage and bumper rubber to restrain the door are installed.

Therefore, in conventional automobile door lock devices, in order to reliably close the door to the fully latched position, it is necessary to apply a large inertial force to the door beyond a certain level, which increases the sound of the door closing and causes discomfort to the occupants. feel or
Since each part receives a strong impact, the durability of the door lock device and door tends to decrease, and as a countermeasure, they are made larger and heavier.Furthermore, the inertial force applied to the door is small and the door does not reach the half-latched position. When the door is only closed, that is, when the door is left ajar, there is a problem in that the door must be closed again, which is cumbersome.

As a conventional example that addressed the above problems,
There is a publication No.-10327.

In this conventional example, a ratchet wheel is provided integrally with the latch, and the ratchet wheel and the ratchet pole engage with each other in the open, half-latched, and fully latched states, and in the half-latched state, The ratchet wheel and latch are rotated by operating the operating member that can be operated from indoors and outdoors.
This allows the door to move to the fully latched state without applying inertia to the door.

However, in this conventional example, a ratchet wheel integrated with the latch and an operating member for rotating the ratchet wheel must be disposed in a narrow door lock device, so the structure of the door lock device is changed. As the door lock device becomes more complex, the door lock device becomes heavier, and as a result, the door to which the door lock device is attached becomes heavier, which tends to cause the door to drop down. Therefore, when used for a sliding door, there was a problem that the operability was poor.

(Objective of the Invention) The present invention has been made by focusing on the above-mentioned problems, and eliminates the small door closing sound without complicating the structure of the door locking device itself or making the door locking device heavy. The purpose of the present invention is to provide a door lock device for an automobile that can reliably close the door.

(Structure of the Invention) In order to achieve such an object, in the present invention, in an automobile door lock device having a half-latch position and a full-latch position, an engaged member provided on the door side is provided with a locking member that is disposed at the half-latch position. 1 member that pivotally supports a pulling lever that engages with the vehicle body side and rotates the pulling lever at the /＼-flatch position, □1.12, -2, 77 positions, 8.5 pulling lever The fully latched state is achieved by pulling the engaged member to the fully latched position.
