Description

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

(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 crosses the half-latch position where the latch is incompletely engaged with the striker. The door is moved to a full latch position where the striker fully engages with the striker, and the door closes. Further, automobile doors are generally provided with a seal rubber for preventing water leakage, a bumper rubber for restraining the door, and the like.

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 makes it difficult for the occupants to close the door. Since the door lock device and the door are made to feel uncomfortable and receive a strong impact, the durability of the door lock device and door tend 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 is in a half-latched position. When the door is only closed up to that point, so-called ajar, there is a problem in that the door must be reclosed, which is cumbersome.

Japanese Patent Publication No. 46-10327 is a conventional example that addresses the above-mentioned problems.

In this conventional example, a latch wheel is provided integrally with the latch, and the latch wheel and the latch pole are configured to mesh with each other in the open state, half-latched state, and fully-latched state, and in the half-latched state, By operating an operating member that can be operated from inside or outside the room, the ratchet wheel and latch are rotated so that the door can be moved to a fully latched state without applying inertial force to the door.

However, in this conventional example, a ratchet wheel that is integral with the latch and an operating member for rotating the ratchet wheel must be provided in a narrow door lock device, so the structure of the door lock device becomes complicated. As the door lock device becomes heavier, the door to which the door lock device is attached becomes heavier, which tends to cause the door to drop down. In addition, since the operating member must be operated from the door side, it is difficult to slide the door lock device. When used for doors, there was a problem of poor operability.

(Object of the Invention) The present invention has been made by focusing on the above-mentioned problems, and can be easily installed on the vehicle body side without complicating the structure of the door lock device itself or making the door lock device heavy. To provide a door lock device for an automobile that is operable, easy to arrange, and can reliably close a door with a small closing sound due to a light closing force.

(Structure of the Invention) In order to achieve the above object, the present invention provides a door lock device for an automobile that is used in conjunction with a door lock body that restrains a door in a half-latched position and a fully-latched position, which includes an engaged member on the door side. At the same time, a pulling lever that engages with the engaged member at the half-latched position is pivoted on the vehicle body, and the pulling lever is rotated at the half-latched position to fully latch the engaged member from the half-latched position. The door lock device for a motor vehicle is characterized in that an operating member is provided to bring the door lock body into a fully latched state by pulling the door lock body to a fully latched position.

When the door is closed, the door lock body temporarily locks the door in the half-latched position, and at this time the engaged member and the pull lever engage. When the pull lever is rotated using the operating member, the engaged member is pulled, and when the door is pulled to the fully latched position, the door lock body becomes fully latched, and even when the door is lightly closed, it can easily change from the half latched state to the full latched state. Can be held securely.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The engaging end portion 23a of the pivot shaft 23 is formed to penetrate the mounting panel 10 and protrude toward the vehicle body.

The latch 24 includes a U-shaped engagement portion 24a,
A half-latch engagement part 24b that engages with the pin 32 of the striker body 3 in a half-latched state to temporarily restrain the door in the half-latched position, and a full-latching engagement part 24b that engages with the pin 32 of the striker body 3 to restrain the door in the full-latched position. An engaging portion 24c is formed.

The striker main body 3 includes a base portion 31 fixed to the mounting panel 20, a pin 32 fastened to the base portion 31 and capable of engaging with the U-shaped engagement portion 24a of the latch 24, and a pin 32 for providing a noise reduction effect. pin 3
2 and a resin cover part 33 fitted onto the outside.

A pull lever 4 is rotatably supported on the pin 32. The pulling lever 4 is formed with an engaging groove 4a that engages with the engaging end 23a of the pivot shaft 23 of the latch 24 at the half-latched position, and an operating cable 5 serving as an operating member for rotating the pulling lever 4. One end 5a of the pull lever 4 is fixed to the pull lever 4.

The other end 5b of the operating cable 5 is connected to an operating handle (not shown) provided on the indoor side, and is connected to an outer tube 5 of the operating cable 5.
