[0006]

[Problems to be solved by the device]

 By the way, in the conventional lid lock device having the fork type latch disclosed in Japanese Utility Model Laid-Open No. 151571/1989, the feeling during operation is poor, and the operability of the latch is significantly reduced due to the shift of the fitting point. In addition, since the sound at the time of mating is loud, the latch must be made of low-strength synthetic resin.

Therefore, an object of the present invention is to solve the above-mentioned drawbacks and to provide a lid lock device which has good operability and produces a small noise when fitted.

[0008]

[Means for achieving the object]

 A lid lock device according to the present invention is rotatably attached to a frame between a frame, a handle pivotally attached to the frame and having a protrusion formed therein, and a locked position and an unlocked position. The key cylinder is slidable and swayable between a closed door position having a pin slidably mounted in a slot formed in the frame and engaging a striker and an open door position where this engagement is released. Between the latch that is movably mounted on the frame and the latch that is engaged with the latch and moved between the unlocked position and the locked position by the key cylinder and the locking and unlocking positions by the protrusion of the handle. It is composed of a stopper that moves between the two and a handle spring that biases the handle to the closed position and biases the latch and the stopper to the closed position.

[0009]

[Action]

 Since the latch is slidably and swingably mounted on the frame between the closed position where the latch engages with the striker and the open position where the latch is disengaged, no sound is generated when the latch abuts the striker. Therefore, the operability is good.

[0010]

【Example】

 An embodiment of the 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 includes a frame 11 and a handle 13 rotatably attached to the frame 11 by a shaft 19 and having a protrusion 12. The key cylinder 14 is mounted on the frame 11 so as to be rotatable between a locked position and an unlocked position, as is known. The frame 11 is provided with a guide wall 20 having a through hole 21 formed therein, and a latch 16 is slidably and swingably disposed in the through hole 21. That is, the latch 16 is slidably and swingably attached to the frame 11 between the closed position where the striker 22 (FIG. 4) is engaged and the open position where the engagement is released. A pin 15 integrally formed with the latch 16 is slidably mounted in the long hole 11a formed in the guide wall 20. Although not shown in detail, a pair of elongated holes 11a are formed at opposite positions of the guide wall 20, and a pair of pins 15 of the latch 16 are slidably arranged in the corresponding elongated holes 11a in a balanced state. Has been done. The stopper 17 penetrates 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 locking position where the protrusion 12 of the handle 13 abuts when the handle 13 rotates and a non-locking position where the protrusion 12 does not abut. It Also, when the handle 17 is rotated when the stopper 17 is in the locking position, the stopper 17 moves downward. As a result, the latch 16 is moved by the protrusion 12 of the handle 13 from the closed position where it is locked to the striker 22 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 brought into 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, the handle spring 18 urges the handle 13 to the closed position and the latch 16 to the closed position via the stopper 17. When the key cylinder 14 is rotated between the locked position and the unlocked position, the stopper 17 penetrates the through hole 21 of the guide wall 20 and the notch 16a of the latch 16 and moves back and forth in the longitudinal direction. At this time, the handle spring 18 is locked by the notch 17a or 17b of the stopper 17 to give a sense of moderation to the rotation of the key cylinder 14.

In the above structure, when the key cylinder 14 is rotated to the locking position by the regular key, the stopper 17 moves from the locking position to the unlocking position on the right side in FIG. As a result, even when the handle 13 is rotated, the protrusion 16 does not contact the end of the stopper 17, so that the latch 16 cannot be moved from the closed position to the open position. When the key cylinder 14 is rotated to the unlocked position by the regular key, the stopper 17 moves from the non-locking position to the locking 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, normally, as shown in FIG. 3, the handle 13 and the latch 16 are biased to the closed position by the handle spring 18. When the lid lock device 10 closes the attached lid, the striker 22 relatively approaches the latch 16 as shown in FIGS. 4 and 5, and the latch 16 resists the elastic force of the handle spring 18 to close the lid 16. Is moved to the open position. At this time, as shown in FIGS. 6 and 7, the pin 15 of the latch 16 moves along the elongated hole 11 a and the latch 16 is rotated around the pin 15. Therefore, since the latch 16 smoothly moves from the closed position to the opened position, no sound is produced when the latch 16 contacts the striker 22, and the operability is improved. After that, the ratchet 16 is automatically returned from the open position to the closed position by the elastic force of the handle spring 18. FIG. 8 shows the state in which the handle 16 is slightly pulled from the state in which the latch 16 in the closed position is locked by the striker 22 and the lid is held in the closed state. In this state, when the handle 13 is manually rotated, the latch 16 is again moved to the door open position along the long hole 11a against the handle spring 18 as shown in FIG. 9, and the latch 16 and the striker are moved. The engagement with 22 can be released.

[0013]

[Effect of the device]

 As described above, in the lid lock device according to the present invention, no sound is generated when the latch abuts the striker, and the operability is good, so that there is an advantage that the lid lock device can be smoothly operated. In addition, since the latch is slidably and swingably attached to the frame, the moving distance of the latch can be reduced, and a wide handle can be secured for the handle, and the latch can be placed in a position slightly displaced from the striker. Even if it is attached, the latch can be operated smoothly.
