Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device for a motor vehicle, and more particularly, to a door lock device, in which a door is closed to a half-latch position which is a so-called half-door state. The present invention relates to a door lock device for an automobile, which can be used for both a device with a closure which is rotated to close a door to a fully closed position and a device with no closure.

[0002]

2. Description of the Related Art For example, a conventional door lock device with a closure as disclosed in Japanese Patent Application Laid-Open No. Hei 7-293083 is uniquely designed on the assumption that a closure is assembled and has no closure. It is manufactured as a completely different structure.

[0003]

Therefore, at the time of their production, at least two production lines, one with a closure and one without, are required, which increases the equipment cost and the production cost. It is a factor. Further, the closure cannot be incorporated into a door lock device without a closure already mounted on the vehicle body, and in such a case, there is a problem that the entire door lock device must be replaced.

The present invention has been made in view of the above-mentioned problems of the prior art, and enables a lock body to be shared between one with a closure and the other without, and a closure without a closure already mounted on a vehicle body. It is an object of the present invention to provide a highly safe automobile door lock device in which a closure can be incorporated later into the door lock device and there is no possibility of malfunction.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) In a lock body provided in one of a vehicle body and a door, a latch provided for engaging and disengaging a striker provided on the other side and a pole for preventing rotation of the latch are provided. The latch can be pivoted between an open position where the latch is disengaged from the striker, a half latch position where the latch is barely engaged with the striker, and a full latch position where the latch is completely engaged with the striker, and the latch is forced from the half latch position to the full latch position. In the automotive door lock device, which can be closed toward the fully closed position via the striker by rotating the door, the latch shaft provided at the rotation center of the latch is provided. A pin protrudes from a side surface of the remote latch, and the pin is rotatable around the latch axis together with the latch on one side surface of the lock body. Through to the window hole provided to the pin, the connection portion of the closure mechanism for forcibly rotating the latch.

(2) In the above item (1), a protruding shaft portion coaxial with the latch shaft is provided on one side surface of the lock body, and the protruding shaft portion and the pin are forcibly rotated by the latch mechanism. Connection part.

(3) A lock body provided on one of the vehicle body and the door is provided with a latch provided on the other side for engaging and disengaging the striker, and a pole for preventing rotation of the latch, and the door is closed. Accordingly, the latch is rotatable between an open position where the latch is disengaged from the striker, a half latch position where the latch is barely engaged with the striker, and a full latch position where the latch is completely engaged with the striker, and the latch is fully latched from the half latch position. A door lock device for an automobile in which the door can be closed toward the fully closed position via the striker by forcibly rotating to a position, the door is provided at the center of rotation of the latch. A pin protrudes from a side surface of the latch away from the latch shaft, and the pin is provided on one side surface of the lock body around the latch shaft together with the latch. A window hole is provided so as to be movable, and a closure base detachably mounted on the lock body is engaged with a tip end of the pin, and is rotated by a driving unit to latch a latch via the pin. A lever for forcibly rotating from the half latch position to the full latch position is provided.

(4) In the above item (3), a protruding shaft portion coaxial with the latch shaft is provided on one side surface of the lock body, and a latch interlocking lever which is one of the levers provided on the closure base is provided. By attaching the end to the closure base so as to be rotatable about the same axis as the protruding shaft, and engaging the tip of the latch interlocking lever with a pin, the latch interlocking lever is integrated with the latch. To rotate.

(5) In the above item (3) or (4), the lock body is provided with an open lever which is linked to the door opening operation means and releases the pawl from the latch and releases the latch by the operation. In addition, a cancel lever is provided on the closure base so as to disconnect the link in the middle of the link mechanism from the drive means to the pin in conjunction with the latch release operation of the open lever.

(6) In the above item (5), the open lever and the cancel lever are pivotally attached to the lock body and the closure base with axes parallel to the axis of the pawl.
