Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod mounting device for a vehicle door lock device, and more particularly to a mounting device for an open lever and a rod extending to a door open handle.

[0002]

2. Description of the Related Art A publicly known Japanese Utility Model Publication No. 45-12667 discloses a connector made of synthetic resin for connecting a lower end of a rod and an elongated hole of a lever.

[0003]

The lever referred to in the known example is intended to be a lever that rotates in both directions, such as a lock lever of a vehicle door lock device, and that rotates in only one direction such as an open lever. It does not target members that do. In the connection between the open lever and the rod, which only needs to rotate in one direction, the elongated hole that requires a connector having a complicated structure is unnecessary.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a vehicle door lock device that engages with a striker fixed to the vehicle body side to maintain the door closed state, one end of an open lever 5 of the door lock device is provided. An engaging pin 7 having a head portion 6 is provided, and a lower end of the rod 1 reaching the door opening handle is a bifurcated portion 3 which can be inserted into the engaging pin 7, and the bifurcated portion 3 includes the engaging pin 7 This is a rod mounting device for a vehicle door lock device in which a cap 10 for preventing disengagement is fitted after being inserted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a rod of a vehicle door lock device, an upper end of which is broken in the drawing is connected to a door opening handle side and a forked portion 3 having a long sliding groove 2 is formed at a lower end thereof. At each tip of the bifurcated portion 3, a claw portion 4 which is projected outward is formed.

Reference numeral 5 is an open lever of the vehicle door lock device, and an engaging pin 7 having a head 6 is planted at one end thereof. A resin body 9 having an annular groove 8 with which the forked portion 3 slidably engages is attached to the outer periphery of the engagement pin 7.

Reference numeral 10 denotes a detachment preventing cap which is attached to the tip of the forked portion 3. The disengagement prevention cap 10 is made of synthetic resin, and locking windows 11 for locking the claw portions 4 of the bifurcated portion 3 are formed on both left and right sides thereof. Reference numeral 12 is a bottom portion of the forked portion 3.

[0008]

The present invention has the above-described structure. First, the lock device having the open lever 5 is fixed to the door, and in this state, the forked portion 3 formed at the lower end of the rod 1 is provided on the outer periphery of the engagement pin 7. The annular groove 8 is inserted into the resin body 9. At this time, in the known example, since the rod is connected to the long hole without cut, a connecting tool having a complicated structure is required, but in the present invention, since the forked portion 3 is formed instead of the long hole, Since it suffices to insert it into the annular groove 8 of the engaging pin 7 using the notch at the tip of the bifurcated portion 3, the mounting is extremely easy.

Next, the disengagement prevention cap 10 is fitted on the protruding end of the forked portion 3. The detachment prevention cap 10 is the rod 1
The open lever 5 when connecting the door to the door open handle.
Since it is intended to prevent the rod 1 from coming off, a very simple structure may be used, and the configuration shown in FIGS. 4 and 5 or a rubber band or the like may be used instead. Note that, in FIG. 2, the rod 1 and the open lever 5 are arranged on a straight line for convenience of description, but in reality, the rod 1 and the open lever 5 are in a substantially orthogonal positional relationship.

The protruding end of the bifurcated portion 3 is provided with a cap 1 for preventing disengagement.
After attaching 0, the upper end of the rod 1 is connected to the door opening handle of the door while adjusting the length of the rod 1.

In the lock device assembled in this manner, the open lever 5 is pushed only in one direction by the operation of the door opening handle, so that when the door opening handle is operated, the open lever 5 is engaged by the bottom portion 12 of the rod 1. Press the dowel pin 7,
The open lever 5 can be rotated, and even if the open handle is released, the engagement pin 7 remains in the long sliding groove 2 and the open lever 5 does not come off from the rod 1.

[0012]

The publicly known Japanese Utility Model Publication No. 45-12667 discloses a connector made of synthetic resin for connecting the lower end of the rod and the long hole of the lever. The lever referred to in the above-mentioned publicly known example is a lever that rotates in both directions, such as a lock lever of a vehicle door lock device, and does not target a member that rotates in only one direction such as an open lever. In the connection between the open lever and the rod, which only needs to rotate in one direction, the elongated hole that requires a connector having a complicated structure is unnecessary. However, the present invention relates to a vehicle door lock device that engages with a striker fixed to the vehicle body side to hold the door closed, and an engagement pin having a head 6 at one end of an open lever 5 of the door lock device. 7 is provided, and the lower end of the rod 1 reaching the door open handle is a bifurcated portion 3 into which the engaging pin 7 can be inserted, and the bifurcated portion 3 has a cap for preventing disengagement after the engaging pin 7 is inserted. Since this is a rod mounting device of the vehicle door lock device in which 10 is fitted, the engaging pin 7 is formed by utilizing the notch at the tip of the forked part 3.
Since it is only necessary to insert it in, it is extremely easy to attach, and a thin connecting portion can be formed.
