DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lid lock device according to the present invention will be described below with reference to FIGS.

The lid lock device 10 according to the present invention is
The vehicle includes a frame 11 and a handle 13 rotatably mounted on the frame 11 by a shaft 19 and having a protrusion 12 formed thereon. The key cylinder 14 is attached to the frame 11 so as to be rotatable between a locked position and an unlocked position, as is well known. The frame 11 is provided with a guide wall 20 in which a through hole 21 is formed. In the through hole 21, the latch 16 is slidably and swingably disposed. That is, the latch 16 is slidably and swingably mounted on the frame 11 between a closed position where it engages with the striker 22 (FIG. 4) and an open position where this engagement is released. Guide wall 2
The pin 15 formed integrally with the latch 16 is slidably mounted in the elongated hole 11a formed at 0. Although not shown in detail, a pair of long holes 1 are
1a is formed, and the pair of pins 15 of the latch 16 are slidably disposed in the corresponding slots 11a in a balanced state. The stopper 17 passes through the through hole 21 formed in the guide wall 20 and the notch 16a of the latch 16 shown in FIG. As is well known, the stopper 17 is moved by the key cylinder 14 between a locked position where the protrusion 12 of the handle 13 abuts when the handle 13 rotates and a non-locked position where the protrusion 12 does not abut. . When the handle 13 is turned while the stopper 17 is at the locking position, the stopper 17 moves downward. As a result, the latch 16 is moved from the closed position where it is locked to the striker 22 by the protrusion 12 of the handle 13 to the open position where it is not locked to the striker 22. One end 18a of the handle spring 18 wound around the shaft 19 is in contact with the handle 13 (not shown), and the other end 18b is engaged with the notch 17a or 17b of the stopper 17. Therefore, handle spring 1
8 urges the handle 13 to the closed position and
7 urges the latch 16 to the closed position. When the key cylinder 14 is rotated between the locked position and the unlocked position, the stopper 17 engages with the through hole 21 of the guide wall 20 and the latch 16.
Reciprocate in the length direction through the notch 16a. At this time, the handle spring 18 is
Is locked in the notch 17a or 17b of the key cylinder 1
Gives a sense of moderation to the rotation of 4.

In the above configuration, when the key cylinder 14 is rotated to the locked position by a proper key, the stopper 17
Moves from the locked position to the non-locked position on the right side in FIG. Thus, even if the handle 13 is rotated, the protrusion 1
2 does not contact the end of the stopper 17,
Cannot be moved from the closed position to the open position. When the key cylinder 14 is rotated to the unlocking position by a proper key, the stopper 17 moves from the unlocked position to the locked position on the left side in FIG. As a result, when the handle 13 is rotated, the protrusion 12 comes into contact with the end of the stopper 17, so that the latch 16 can be moved from the closed position to the open position. That is, usually, as shown in FIG.
The handle 3 and the latch 16 are urged to a closed position by a handle spring 18. When the lid to which the lid lock device 10 is attached is closed, the striker 22 relatively approaches the latch 16 as shown in FIGS.
The latch 16 is moved from the closed position to the open position against the elasticity of the handle spring 18. At this time, as shown in FIGS. 6 and 7, the pin 15 of the latch 16 is
And the latch 16 is rotated about the pin 15. Therefore, since the latch 16 smoothly moves from the door closing position to the door opening position, no sound is generated when the latch 16 comes into contact with the striker 22, thereby improving operability. Thereafter, the latch 16 is automatically returned from the open position to the closed position by the elasticity of the handle spring 18. FIG. 8 shows a state in which the latch 16 at the door closing position is locked to the striker 22 and the handle 13 is slightly pulled from the state where the lid is held in the closed state. In this state, the handle 13
Is manually rotated, the latch 16 is again moved to the door opening position against the handle spring 18 along the long hole 11a as shown in FIG. 9, and the engagement between the latch 16 and the striker 22 is released. be able to.

[0013]

As described above, in the lid lock device according to the present invention, no sound is generated when the latch abuts on the striker, and the operability is improved, so that the lid lock device can be operated smoothly. There is. In addition, since the latch is slidably and slidably attached to the frame, the movement distance of the latch is reduced, a wide handle for the handle can be secured, and the latch is mounted at a position slightly displaced from the striker. Even if it is set, the latch can be operated smoothly.
