Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a luggage door lock device having a cancel mechanism, which is used in a vehicle trunk lid or the like.

"Prior art and its problems" This type of lock device has the basic function of being able to be unlocked using both the key and the opener handle located inside the vehicle, and furthermore, in the canceled state, the lock cannot be unlocked using the opener handle. It is. Referring to FIG. 5, an example of the structure of a conventional locking device of this type and its problems will be explained.

This locking device is proposed in Japanese Utility Model Publication No. 52-18807, in which a base 11 fixed to either the vehicle body or the lid is formed with an entry opening 13 for a striker 12 fixed to the other. A ratchet 16 and a hook 17 are pivotally mounted on the left and right sides of this striker entry opening 13 by shafts 14 and 15. The hook 17 has a locking recess 18 that holds the striker 12 and a locking portion 20 that engages and disengages with the lock pawl 19 of the ratchet 16.
2 is rotationally biased in the direction of arrow A to open it.
On the other hand, the ratchet 16 has its locking pawl 19.
is biased to rotate in the direction of arrow B where it engages with the locking portion 20, and when both are engaged, the hook 17 locks the striker 12 and holds the lid in the closed position. One end of an opener cable 21 is connected to the ratchet 16, and the other end of the opener cable 21 is connected to an opener handle (not shown) disposed inside the vehicle interior.

On the base 11 are a ratchet 16 and a hook 1.
7, the cancel lever 2 is attached with a shaft 22.
3 is pivoted. This cancel lever 23
is rotated by a key, and when rotated in the direction of arrow C in FIG. 5, the latch 16 is pushed and rotated in the unlocking direction away from the hook 17. On the other hand, when it is rotated in the direction of arrow D and moved to the cancel position shown by the chain line, it comes into contact with the hook 17 and prevents it from rotating to the unlocked position.

Therefore, according to this luggage door lock device, when the cancel lever 23 is in the solid line state shown in FIG.
1 and by rotating the cancel lever 23 in the direction of arrow C using the key, the ratchet 16 is rotated to a non-meshing position with the hook 17, and the latch 16 is held by the hook 17. The striker 12 that is present can be released. To cancel the operation, use the key to rotate the cancel lever 23 to the chain line position. Then, even if the latch 16 is pulled by the opener cable 21, the lock cannot be released because the rotation of the hook 17 in the unlocking direction is blocked by the cancel lever 23.

However, in this conventional device, the cancel lever 2
Even in the cancel state where the latch 3 is rotated to the chain line position, when the opener cable 21 is pulled, the ratchet 16 rotates. Then, the clearance between the parts,
Due to dimensional errors and the like, the hook 17 also rotates slightly in the unlocking direction due to the rotation urging force applied thereto. Then, while the hook 17 is rotating, release the opener cable 21 and release the ratchet 1.
When 6 is restored, lock pawl 1 of ratchet 16
9 rides on a part of the hook 17, and the contact resistance between the cancel lever 23 and the hook 17 increases.
There was a problem in that the rotational operation force of the cancel lever 23 by the key was increased. Many locking devices having this type of cancel mechanism are known in addition to the illustrated example, but the basic structure is the same as that described above, and therefore there are similar problems.

``Purpose of the invention'' The purpose of the present invention is to solve the problems of the conventional device described above, that is, to create a locking device that does not affect the engagement of the ratchet and hook even if the opener handle on the indoor side is operated in the cancel state. The purpose is to obtain.

Another object of the present invention is to provide a locking device that has a simple structure of individual parts, can be assembled to a base in a good condition, and has more reliable operation.

``Summary of the invention'' The invention consists of a striker fixed to either one of the car body and a lid provided on the car body so as to be openable and closable, and a base fixed to the other;
A hook that is pivotally connected to the base by a rotation support shaft and holds and releases the striker; A hook that is pivotally connected to the base by a second rotation support shaft and rotates between a lock position where it engages with the hook and a lock release position where it separates from the hook. a key device capable of unlocking the striker by key operation; and an opener handle provided inside the vehicle and capable of unlocking the striker by operating the key device; The key device, which is connected to the device via a key link and activated by key operation, can be set to a lock position where the ratchet can be engaged, an unlock position where the ratchet can be rotated in the unlock direction, and a cancel position. A transfer lever that is rotated; is connected to the opener handle, rotates in conjunction with the operation of the opener handle, and when the transfer lever is in the lock position, comes into contact with the transfer lever and rotates to the unlocked position. the transfer lever and the opener lever that do not come into contact with the transfer lever when the transfer lever is in the cancel position; It is characterized in that it is pivotally connected to the base by means of third and fourth rotational support shafts different from the rotational support shaft, at positions different from those of the hook and the ratchet.

``Embodiments of the invention'' The invention will be described below with reference to illustrated embodiments. 1 to 4 show an embodiment of the present invention, and the same elements as those of the conventional device shown in FIG. 5 are given the same reference numerals.

Shafts 14,
15, a ratchet 16 and a hook 17 are pivotally connected. A transfer lever 32 is pivotally attached to the base 11 by a shaft 30 adjacent to the latch 16 and at a different pivot position from the latch 16. Further, an opener lever 33 is pivotally attached to the base 11 by a shaft 31 adjacent to the transfer lever 32 and at a pivot position different from that of the ratchet 16.

The transfer lever 32 has a pair of arms 32a,
32b, and a key link 34 on one arm 32a.
one end is connected. The other end of this key link 34 is fitted into an eccentric pin 37 of a key rotor 36 which is rotated by a key 35. Therefore, when the key rotor 36 is rotated, the key link 34 is moved in the axial direction, and the transfer lever 32 is rotated. Further, a bent piece 32c interlocking with the opener lever 33 is formed on this arm 32a.

A bent piece 32d interlocking with the ratchet 16 is formed at the tip of the other arm 32b. When the key rotor 36 is in the neutral position, this interlocking bending piece 32d is in the lock position shown in FIG. 1, and maintains a small gap from the ratchet 16. However, when the key rotor 36 is rotated to the unlocked position and the transfer lever 32 is rotated clockwise in the figure via the key link 34, this interlocking bending piece 32d pushes the latch 16 in the unlocking direction and locks the lock pawl 19. The locking portion 20 is disengaged from the hook 17, and the striker 12 held in the locking recess 18 is released. Further, when the key rotor 36 is rotated to the cancel position, the transfer lever 32 is rotated to the position shown in FIG. 4.

The opener lever 33 has a pair of arms 33a and 33b.
has. One arm 33a is connected to one end of an opener cable 21, and the other end of this opener cable 21 is connected to an opener handle 38 inside the vehicle. The other arm 33b is engageable with the interlocking bending piece 32c of the transfer lever 32 in the locked position. However, when the transfer lever 32 is rotated to the cancel position shown in FIG. 4, this arm 33b cannot engage with the interlocking bending piece 32c. The transfer lever 32 is swung in vain.

This device having the above configuration operates as follows. First, when the key rotor 36 is rotated to the unlocked position using the key 35 in the locked state shown in FIG. 1, the transfer lever 32 is rotated clockwise in the figure via the key link 34, as described above. As a result, the interlocking bending piece 32d pushes the latch 16 in the unlocking direction to disengage the lock pawl 19 and the locking portion 20, so that the striker 12 held in the locking recess 18 of the hook 17 is released. In other words, the lid opens.

On the other hand, when the opener cable 21 is pulled using the opener handle 38 inside the vehicle, the opener lever 33 rotates counterclockwise, and the arm 33b presses the interlocking bending piece 32c of the transfer lever 32, causing it to move clockwise. Rotate it. If we only look at the transfer lever 32, this state is the same as the above case in which the transfer lever 32 itself is rotated by the key rotor 36, and therefore the lock is released in the same way.

Next, when the key rotor 36 is rotated to the cancel position using the key 35, the transfer lever 3
2 is rotated to the position shown in FIG. In this state, even if the opener lever 33 is rotated by the opener cable 21, the arm 33b does not engage with the interlocking bending piece 32c. In other words, the opener lever 33 is in a state where it is not swung relative to the transfer lever 32, and the lid cannot be opened by the opener handle 38 inside the vehicle.

In the present invention, when the opener cable 21 is pulled in this cancel state, no external force is applied to the ratchet 16 and the hook 17, unlike the conventional device. Therefore, even if the opener handle 38 is opened after being pulled, there will be no abnormality in the engagement between the lock pawl 19 of the ratchet 16 and the locking portion 20 of the hook 17, and the lock can be unlocked using the key. There is no problem of an increase in the rotational operation force during the operation.

``Effect of the invention'' As described above, according to the invention, in the cancel state, even if the opener handle inside the car is operated, no external force is applied to the hook that holds the striker and the ratchet that holds this hook in the lock position. . Therefore, there is no possibility that the force required to release the lock using the key will increase.

Also, the transfer lever and opener lever,
Because it is pivoted to the base separately from the ratchet,
The individual component configurations are simplified and can be properly assembled to the base without rattling. As a result, it is possible to eliminate problems such as failure to operate properly due to looseness of various parts, and to obtain a lock device that operates more reliably. Further, since the transfer lever is connected to the key device by a key link, its operation is ensured.

Furthermore, since the transfer lever, opener lever, etc. are pivoted to the base separately from the key device, there is plenty of installation space, and there is no need to force each member into a complicated or unreasonable shape. It is possible to robustly configure
Problems such as malfunctions can be extremely reduced.
