[Industrial applications]

 The present invention relates to a locking device, particularly a lid locking device attached to a glove box lid of a vehicle.

[0002]

[Prior art]

 For example, Japanese Utility Model Laid-Open No. 61-1572 discloses an automobile door lock device. This door lock device is provided with a lock body attached to the door of the glove box, a striker provided so as to correspond to the lock body when the door is closed, and a rotatably provided lock body. A ratchet having a U-shaped holding portion that engages and holds the striker when the door is closed, and a lock body that is provided so as to be exposed from the outer surface of the door and supports the upper end of the lock body and pulls the lower end. A handle for releasing the engagement and holding of the ratchet and opening the door is provided. Further, the lock body is provided with a stopper which is operated by a key cylinder between a locked position and an unlocked position. Further, when the stopper is in the unlocked position, it is moved by the handle to the unlocked position, moving the ratchet to the unlocked position.

Further, as disclosed in Japanese Utility Model Laid-Open No. 62-36158, a ratchet rotatably attached to a lock body, a ratchet spring for urging the ratchet, and a protrusion are formed. A grab door locking device having a handle pivotally attached to a lock body, a handle spring that urges the handle to a non-operating position, and a stop lever that is operated by a protrusion of the handle and holds a ratchet in a locking position. A mechanism for elastically holding the stop plate by extending one end of the handle spring and engaging it with the lower edge of the stop plate is known.

In addition, Japanese Utility Model Laid-Open No. 1-157171 discloses a lid lock device that is easy to assemble and does not generate vibration noise.

Further, Japanese Utility Model Laid-Open No. 62-146859 discloses a glove box lock device provided with a slider that engages with a striker.

Although not publicly known, a lid lock device shown in FIGS. 9 to 17 has been proposed. The lid lock device 10 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. A guide wall 20 having a through hole 21 is provided in the frame 11, and a dog 16 is slidably and swingably arranged in the through hole 21. That is, the dog 16 is slidably and swingably attached to the frame 11 between the closed position where the striker 22 (FIG. 12) is engaged and the open position where the engagement is released. A pin 15 formed integrally with a dog 16 is slidably mounted in the elongated 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 so that the pair of pins 15 of the dog 16 can slide in the corresponding elongated holes 11a in a balanced state. It is arranged. The lever 17 penetrates the through hole 21 formed in the guide wall 20 and the cutout portion 16a of the dog 16 shown in FIG. As is well known, the lever 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 an unlocked position where the protrusion 12 does not abut. . Further, when the handle 13 is rotated while the lever 17 is in the locking position, the lever 17 moves downward. As a result, the dog 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 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 lever 17. Therefore, the spring 18 biases the dog 16 to the closed position. When the key cylinder 14 is rotated between the locked position and the unlocked position, the lever 17 reciprocates in the length direction through the through hole 21 of the guide wall 20 and the notch 16a of the dog 16. At this time, the spring 18 is engaged with the notch 17a or 17b of the lever 17 and gives a moderation to the rotation of the key cylinder 14.

In the above configuration, when the key cylinder 14 is rotated to the locked position by the regular key, the lever 17 moves from the locked position to the unlocked position on the right side in FIG. As a result, even if the handle 13 is rotated, the projecting portion 12 does not contact the end portion of the lever 17, so that the dog 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 lever 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 lever 17, so that the dog 16 can be moved from the closed position to the open position. That is, normally, as shown in FIG. 11, the handle 13 and the dog 16 are biased to the closed position by the spring 18. When the lid lock device 10 closes the attached lid, the striker 22 relatively approaches the dog 16 as shown in FIGS. 12 and 13, and the dog 16 is in the closed position against the elasticity of the spring 18. Is moved to the open position. At this time, as shown in FIGS. 14 and 15, the pin 15 of the dog 16 moves along the long hole 11 a and the dog 16 is rotated around the pin 15. Therefore, since the dog 16 smoothly moves from the closed position to the opened position, no sound is generated when the dog 16 contacts the striker 22 and operability is improved. Thereafter, the dog 16 is automatically returned from the open position to the closed position by the elasticity of the spring 18. FIG. 16 shows a state in which the dog 16 in the closed position is locked by the striker 22 and the handle 13 is slightly pulled from the state in which the lid is held in the closed state. When the handle 13 is manually rotated in this state, the dog 16 is again moved to the open position along the elongated hole 11a against the spring 18 as shown in FIG. 17, and the dog 16 and the striker are moved. The engagement with 22 can be released.

[0009]

[Problems to be solved by the device]

 By the way, in the conventional lid lock device 10, the operability at the time of rotating the key cylinder 14 is not good, and a considerable time is required for assembling. That is, since the shape of the spring 18 is large and complicated, it takes a long time to manufacture the spring 18. Further, since the spring 18 generates a reaction force when the lever 17 moves, the key cylinder 14 cannot rotate smoothly. Further, since one end 18a of the spring 18 is brought into contact with the handle 13 (not shown) and the other end 18b is locked in the notch 17a or 17b of the lever 17, the assembly is not easy.

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 is easy to assemble.

[0011]

[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 rotatably attached to the frame and having a protrusion, and a locked position and an unlocked position. A key cylinder, a dog mounted on the frame so that it can move between a closed door position that engages the striker and an open door position where this engagement is released, and an unlocked position by the key cylinder that engages the dog. A lever that is moved between a locked position and a locked position and is moved between a locked position and a non-locked position by the protrusion of the handle; and a spring that urges the dog to the closed position. In this lid lock device, a lever having an elastic projection and a cutout is integrally formed of resin, and a cam projection provided on the key cylinder is fitted into the cutout of the lever. The supporting protrusions provided on the frame are brought into contact with the elastic protrusions of the lever, and when the dog is returned from the open position to the closed position, the elasticity of the spring causes the lever to return to the closed position together with the dog. The lever has a guide protrusion facing the elastic protrusion at a constant distance, and when the lever is moved to the unlocked position, the support protrusion of the frame is locked by the guide protrusion. In the illustrated embodiment, a claw portion is formed at the tip of the elastic protrusion of the lever, and a groove is formed at the tip of the support protrusion of the frame. The elastic protrusion or guide protrusion of the lever is fitted into the groove of the frame.

[0012]

[Action]

 Since the elastic projection integrally molded with the lever on the resin is engaged with the support projection of the frame, it is not necessary to use a spring having a complicated shape. In addition, since the spring force is not applied when the key cylinder rotates, the operability of rotating the key cylinder is improved.

[0013]

【Example】

 An embodiment of a lid lock device according to the present invention will be described below with reference to FIGS. In these drawings, the same parts as those shown in FIGS. 9 to 17 are designated by the same reference numerals, and the description thereof will be omitted.

In the lid lock device according to the present invention, as shown in FIGS. 1 and 5, the lever 17 having the elastic protrusion 31 and the notch 32 is integrally molded with resin, and the cam protrusion 33 provided on the key cylinder 14 is provided with the lever protrusion. It is fitted in the notch 32 of 17. The lever 17 has a guide protrusion 35 that faces the elastic protrusion 31 with a gap 39 at a constant distance therebetween, and a recess 38 is formed in the lever 17 by the elastic protrusion 31 and the guide protrusion 35. A claw portion 36 is formed at the tip of the elastic projection 31 of the lever 17, and a groove 37 (FIG. 4) is formed at the tip of the support projection 34 of the frame 11. By mounting the support protrusion 34 provided on the frame 11 in the recess 38, the support protrusion 34 is brought into contact with the elastic protrusion 31 of the lever 17. The elastic protrusion 31 or the guide protrusion 35 of the lever 17 is fitted into the groove portion 37 of the frame 11 to position the lever 17. The dog 16 is biased by the spring 30 toward the closed position.

In the above configuration, when the key cylinder 14 is in the unlocked position, the key cylinder 14 is in the position shown in FIGS. 1, 5 and 7. In this state, when the handle 13 is manually pulled to perform the pull-up operation, the lever 17 is rotated to the state shown in FIGS. At this time, the elastic protrusion 31 is deformed outward as shown by the dotted line in FIG. 5, and the dog 16 is moved from the closed position to the open position against the elasticity of the spring 30. When the handle 13 is released, the handle 13 returns to the initial position by the elastic force of the spring 18, but at the same time, the dog 16 returns from the open position to the closed position. Further, the elastic force of the elastic protrusion 31 of the lever 17 returns the lever 17 together with the dog 16 from the open position shown in FIG. 2 to the closed position shown in FIG.

When the key cylinder 14 is moved from the locked position shown in FIG. 1 to the locked position shown in FIGS. 3, 6 and 8 using a regular key, the lever 17 is moved to the unlocked position, The support protrusion 34 of the frame 11 is locked to the guide protrusion 35. Therefore, the lever 17 does not move the dog 16 to the unlocked position.

In this invention, since the elastic protrusion 31 integrally formed on the lever 17 with resin is engaged with the support protrusion 34 of the frame 11, it is not necessary to form the spring 18 in a complicated shape. Further, since the spring force is not applied when the key cylinder 14 is rotated, the operability of the rotation of the key cylinder 14 is improved.

[0018]

[Effect of device]

 As described above, in the lid lock device according to the present invention, the spring is not complicatedly attached and is not locked to the lever as in the conventional case, so that there is an advantage that the assembly is easy and the key cylinder can be smoothly rotated. .
