The present invention relates to a locking device for a vehicle door that is opened and closed about a horizontal axis; a hook that holds and releases a striker; a ratchet that engages and disengages with the hook and holds the hook at a striker holding position; a key lock. A key lever that is connected to a key link that moves back and forth substantially in the left-right direction depending on a release position, an unlocking operation position, and a lock position, and that rotates around an axis at a position corresponding to each position; , An opener lever that rotates in conjunction with the opener; a lock release leg that can be engaged with the ratchet, and a rotational movement about the axis of the key lever and the opener lever, and a movement in a substantially vertical direction relative to the axis. A lock release / cancel lever that allows movement; the key lever turns from the lock release position to the unlocking operation position by the movement of the key link in the substantially left-right direction. When the lock release / cancel lever is rotated together with the key lever to release the lock by the lock release leg, the interlocking rotation means is operated; when the key lever is at the lock release position, the opener lever is rotated to release the lock. Interlocking rotating means for rotating the cancel lever together with the opener lever to release the lock by its unlocking leg; and a lock releasing and canceling lever when the key lever is rotated to the lock position by the movement of the key link in the substantially left-right direction. Is moved relatively upward with respect to the opener lever, and idle swinging means for preventing the rotation of the opener lever from being transmitted to the lock release / cancel lever is provided.

"Embodiment of the Invention" The present invention will be described below with reference to illustrated embodiments. The figure shows an embodiment of the present invention. For example, a base 11 fixed to the body side is formed with an entry groove 13 of a striker 12 fixed to the vehicle door side which is opened / closed about a horizontal axis. Has been done. Hooks on both sides of this striker entry groove 13
A 15 and a ratchet 16 are pivotally mounted on shafts 15a and 16a, respectively. The hook 15 has a holding groove 15b of the striker 12 and an engaging portion 15c with which the ratchet 16 is engaged, while the ratchet 16 has an engaging portion 16c with which the engaging portion 15c of the hook 15 is disengaged. The hook 15 and ratchet 16 are tension springs stretched between them.
17 urges them to rotate in opposite directions. This urging direction is a direction in which the hook 15 releases the striker 12, and the engaging portion 15c of the hook 15 and the engaging portion 16c of the ratchet 16 are provided.
Holds the hook 15 at the holding position of the striker 12 against the urging force when engaged.

In addition to the key lever 20 on the base 11 by the shaft 18,
The opener lever 21 is coaxially and pivotally attached. The key lever 20 has an interlocking forked protrusion 20a, and the key link 22 has a pin 2
It is pivoted at 3. The key link 22 moves in the axial direction according to the rotation of the key cylinder, which is rotated by the key, to the unlock position, the unlocking position, and the lock position (cancel position), and the key lever 20 Is rotated about the shaft 18. FIG. 1 shows the unlocked position of the key link 22 (key lever 20), FIG. 2 shows the unlocking operation position, and FIG. 3 shows the locked position. One of the features of this embodiment is that the key link 22
The moving direction of is a direction orthogonal to the direction of the striker entry groove 13. That is, the key cylinder is arranged at the lateral position of the lock device, and the key link 22 moves in the substantially left-right direction by a key operation.

One end of an opener wire 25 is connected to the opener lever 21. The opener wire 25 passes through an outer cable 26 having one end fixed to the base 11 and is connected to an opener inside and outside the vehicle. Therefore, when the opener is operated, the opener lever 21 rotates about the shaft 18 in the unlocking direction (clockwise in the figure). Reference numeral 25a is a stop roller provided at the tip of the opener wire 25. The opener lever 21 has a spring hook leg 21a.
A tension spring 28 stretched between the base 1a and the base 1a is constantly biased to rotate in the locking direction (counterclockwise direction in the drawing). The extension direction of the opener wire 25 is substantially orthogonal to the moving direction of the key link 22 in this embodiment.

The key lever 20 and the opener lever 21 are not related to each other, as is apparent from the above description. That is, when the key is operated, the key lever is
When the 20 rotates independently and the opener is operated, the opener lever 21 independently rotates via the opener wire 25. Further, even if either of them rotates, the ratchet 16 does not directly rotate.

The key lever 20 and the opener lever 21 are associated with the ratchet 16 via an unlock / cancel lever 30. This unlocking / cancelling lever 30 has an arc hole 31 into which the shaft 18 is fitted, so that it can rotate about the shaft 18 and the shaft 18 (that is, the key lever 20).
And relative movements (with respect to the opener lever 21) are possible.

This unlock / cancel lever 30 is a ratchet
The lock release leg 30a that engages with 16, the interlocking protrusion 30b that enters the interlocking forked protrusion 20a of the key lever 20, the interlocking / cancelling protrusion 30c with the opener lever 21, and the rotation fulcrum leg 30d.
And

The interlocking protrusion 30b is for rotating and moving the lock release / cancel lever 30 integrally with the key lever 20.

The unlocking leg 30a is provided with the unlocking / cancel lever 3
When 0 rotates clockwise in the figure, ratchet 16
Press to release the engagement between the engaging part 16c and the engaging part 15c, and
This is for releasing the holding of the striker 12 by 15b.

The interlocking and canceling projection 30c is an opener when the unlocking and canceling lever 30 is at the lower position as shown in FIGS. 1 and 2, that is, when the shaft 18 is located at the upper end of the arc hole 31 in the drawing. Interlocking rotation surface 21b of the lever 21 (Fig. 5,
(See Fig. 6), the opener lever
The lock release / cancel lever 30 is rotated in the same direction in conjunction with the rotation of the lock release direction of 21. On the other hand, when the unlocking / cancelling lever 30 is at the upper position as shown in FIG. 3, that is, when the shaft 18 is located at the lower end of the arc hole 31 in the figure, the interlocking / cancelling projection 30c is not opened by the opener lever 2.
It is located at a position separated from the interlocking rotary surface 21b of 1 in the upper part of the figure. At this time, even if the opener lever 21 rotates in the unlocking direction, the unlocking and canceling lever 30 does not rotate.

When the key lever 20 is in the unlocked position shown in FIG. 1, the rotation fulcrum leg 30d comes into contact with or approaches the stopper projection 11a formed upright on the base 11. When the key lever 20 is rotated from this state to the lock position (cancel position) shown in FIG. 3, the lock release and cancel lever 30 is released.
Moves upward along the arc hole 31 and the shaft 18 while using the tip of the rotation fulcrum leg 30d as a rotation fulcrum. Therefore, the arc of the shaft 18 is formed as an arc centered on the virtual center point 30e when the lock release / cancel lever 30 is rotated.

The device having the above structure operates as follows. In the unlocked position of the key lever 20 in FIG. 1, when the key is unlocked, the key link 22 moves as shown in FIG. Then, the key lever 20 rotates clockwise about the shaft 18, and the lock release / cancel lever 30 rotates in the same direction via the interlocking forked protrusion 20a and the interlocking protrusion 30b. Therefore, the unlocking leg 30a hits the ratchet 16 and the engaging portion 1
Since the engagement between 6c and the engaging portion 15c is released, the force of the tension spring 17 causes the hook 15 to rotate in the unlocking direction, and the striker 12 held in the holding groove 15b is released. That is, the lock is released.

When the opener is operated to pull the opener wire 25 at the unlocked position of the key lever 20 shown in FIG. 1, the opener lever 21 rotates about the shaft 18 in the unlocked direction. Then, at this time, the lock release / cancel lever 30 is in the lowered position, and the interlocking / cancelling protrusion 30c is in the engagement position with the interlocking rotating surface 21b of the opener lever 21, so that both the lock releasing / canceling lever 30 are moved. Rotate. Therefore, the same operation as described above,
The ratchet 16 is hit by the unlocking leg 30a to unlock the ratchet 16. That is, the lock can be released by operating the key or the opener.

On the other hand, when the key cylinder is rotated from the unlocked position shown in FIG. 1 to the locked position by a key operation, the key link 22 moves to the position shown in FIG. Then, the key lever 20 rotates counterclockwise about the shaft 18 and the interlocking bifurcation
The lock release / cancel lever 30 is pulled in the same direction via the 20a and the interlocking protrusion 30b. At this time, since the rotation fulcrum leg 30d of the lock release / cancel lever 30 is in contact with the stopper projection 11a of the base 11 and is prevented from rotating, the lock release / cancel lever 30 has the shaft 18 and the arc. Hole
According to 31, the fulcrum moves upward while the virtual center point 30e at the tip of the fulcrum leg 30d is used as the fulcrum of rotation. When moving upward, the interlocking / cancelling protrusion 30c will move to the opener lever 21
The position is changed so as to be disengaged from the interlocking rotating surface 21b of the above in the figure. In this state, if the opener wire 25 is pulled through the opener, the opener lever 21 rotates in the unlocking direction, but the non-interlocking recess 21c misses the interlocking / cancelling projection 30c, and the rotation of the opener lever 21 is locked. It is not transmitted to the release / cancel lever 30. That is, the movement of the opener is canceled and the lock is not released.

When the key cylinder is returned to the unlocked position from the state shown in FIG. 3 by the key operation, the key link 22, the key lever 20 and the unlock / cancel lever 30 return to the unlocked position shown in FIG.

In the above embodiment, when the key lever 20 is rotated to the lock position, the lock release / cancel lever 30 makes a rotational movement to move relative to the opener lever 21, but the lock release cancel lever 30 moves straight. Let me
The rotation of the opener lever 20 may not be transmitted to the lock release / cancel lever 30.

[Advantage of the Invention] As described above, in the present invention, the key lever, the opener lever, and the lock release / cancel lever are coaxially arranged, and the lock release / cancel lever moves relative to the opener lever to form the cancel mechanism. To be done. Such a lock device having a canceling mechanism with a triple lever structure is particularly useful in a lock device in which the vehicle door can be opened and closed about a horizontal axis and the key and the lock device are arranged in a horizontal position. The cancel mechanism can be configured by converting the movement in the substantially horizontal direction into the movement in the substantially vertical direction of the lock release / cancel lever.
