Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention is applied to, for example, a tail hatch,
The present invention relates to a latch structure for a vehicle opening / closing member such as a trunk lid.

[0002]

2. Description of the Related Art A latch structure of this kind is disclosed, for example, in Japanese Utility Model Publication 55.
As disclosed in Japanese Laid-Open Patent Publication No. 61154, a substrate is provided with first and second shafts substantially parallel to each other with a predetermined space therebetween, and a first position where a striker can be locked and a striker are released. The first shaft in such a manner that a first locking member (generally referred to as a "fork lever") rotatable relative to the second position is spring-biased toward the second position. A second locking member that is pivotally supported by the and is rotatable between a locked position and an unlocked position (generally referred to as a "claw lever").
Is pivotally supported by the second shaft, and the claw lever engages with the fork lever in the locking position to lock the fork lever in the first position and is rotated to the unlocking position. Accordingly, the fork lever is allowed to pivot to the second position and unlocked.

However, in such a conventional latch structure, the strength of the lock device including the fork lever and the claw lever must be increased in order to prevent the locking from being released by the impact in the case of a rear-end collision, for example. However, there is a drawback that the weight increases.

[0004]

The problem to be solved is that the engagement between the fork lever and the claw lever is disengaged by the impact.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a set plate supporting a shaft of a fork lever and a shaft of a claw lever is provided with a flange close to an engaging portion of the fork lever and the claw lever. Characterize. This prevents disengagement of the fork lever and the claw lever.

1 is a perspective view of an embodiment of a latch structure according to the present invention, and FIG. 2 is a plan view showing a meshing state of a fork lever and a claw lever in a locked position. 3 is a plan view showing an unlocked state, and FIG. 4 is IV-IV of FIG.
It is sectional drawing along the line.

Reference numeral 1 denotes a latch base which is attached to the vehicle body by bolts 2 and 2 on which two shafts 3 and 4 are substantially perpendicular to the surface of the latch base 1 and thus substantially parallel to each other. It is erected at a predetermined interval. The tips of the shafts 3 and 4 are caulked to a set plate 5 arranged to face the latch base 1,
The set plate 5 is extended so as to overlap the vehicle body mounting portions 1a and 1b of the latch base 1 as required, and is fastened together with the latch base 1 to the vehicle body by bolts 2 and 2. Fork lever 6 on shafts 3 and 4
And claw lever 7 are rotatably supported. The fork lever 6 includes a locking groove 6a that locks the striker 8 so as to sandwich the striker 8 and the striker 8 in the locking groove 6a.
The claw lever 7 is provided with a meshing concave portion 6b which meshes with the meshing convex portion 7a of the claw lever 7. The fork lever 6 and the claw lever 7 respectively include bent portions 6a and 7b to which both ends of the spring 9 are attached,
The spring 9 causes the fork lever 6 to be spring biased around the shaft 3 in the counterclockwise direction of FIGS. 2 and 3, and the claw lever 7 to be spring biased around the shaft 4 in the clockwise direction of FIGS. ing. An end portion 7c of the claw lever 7 on the side opposite to the engagement convex portion 7a side with respect to the shaft 4 has an engaging portion 1 of an opener lever 11 rotatably supported by the shaft 10.
It is in contact with 1a. An opener cable 12 is connected to the opener lever 11, and when the opener cable 12 is operated from the driver's seat, the opener lever 10 is rotated clockwise as shown in FIG. 3 to move the claw lever 7 counterclockwise. It rotates in the direction to release the engagement state of the claw lever 7 with the fork lever 6. Therefore, the fork lever 6 is rotated counterclockwise by the biasing force of the spring 9 to release the striker 8.

At one end of the set plate 5, there is formed a flange 5a bent substantially at a right angle toward the engaging portions 6b and 7a of the fork lever 6 and the claw lever 7. As is apparent from FIGS. 1 and 4, the tip edge of the flange 5a is substantially parallel to the surfaces of the fork lever 6 and the claw lever 7 and is separated from the fork lever 6 and the claw lever 7 with a slight gap. Interlocking part 6
It faces b and 7a. Therefore, fork lever 6
Even if the claw lever 7 is relatively displaced due to impact, the displacement is caused by the flange 5 of the set plate 5.
It is minimized by a, and the disengagement of the engagement portions 6b and 7a is prevented.

[0009]

As described above, in the latch structure for the vehicle opening / closing member according to the present invention, the flange 5a is provided on the set plate 5 close to the engaging portion between the fork lever 6 and the claw lever 7. , Fork lever 6 and claw lever 7 due to impact in the event of a rear-end collision
There is an advantage that it can prevent disengagement with.
