Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door locking device for a vehicle, which is capable of reliably locking a vehicle door according to the user's preference by operating an operating lever inside the vehicle interior, and is capable of locking a door in a locked state according to the user's preference. The aim is to prevent people from becoming trapped.

The configuration of an embodiment of the present invention will be explained with reference to the accompanying drawings.
In Figure 1, 1 is the automobile door assembly, 1a is the door body, 2 is the locking button, 3 is the outside handle, 4 is the inside handle, 5, 6, 7.8 are the links, and 9 is the interior side. The operating lever, 10.11 is a bell crank, and 12 is a base plate.

In FIG. 2, numeral 13 indicates the entire device of the present invention, four screw holes 14 are for attaching the door lock device 13 of the present invention to the door body 1a, and 15 is an open lever that is connected to the door by a pin 16. It is pivotally attached to the base plate 12 and biased clockwise by a spring 17.

The link 5 and the intermediate link 18 are connected to one end of the lever 15.
are pivotally connected by a pin 19, and one end 10a (FIG. 3) of the bell crank 10 is engaged with the other end.

The bell crank 10 is pivotally connected to the base plate 12 by a pin 20, and the other end 10b is connected to the inside handle 4 via the link 7.

The intermediate link 18 has portions 18a and 18c bent toward the back side in the direction perpendicular to the plane of the paper at the center thereof, and a long hole 18b is provided at the lower end thereof.

A locking lever 22 is inserted into the hole 18b via a pin 21.
The upper end 22a is pivotally attached, and the lever 22 is connected to the pin 2.
3, and when the intermediate link 18 is rotated clockwise and positioned in the solid line state (this is the "unlocked position"), the intermediate link 18 is also located in the solid line state together with the pin 21.

Stoppers 12a and 1 are provided at the bottom end of the base plate 12.
2b is provided, so the locking lever 22 is in the solid line state (when it is in this state, it is the "unlocked position")
It rotates within the range indicated by the two-dot chain line.

This rotational action is a so-called "snap action."

That is, by the action of the spring 24 whose one end is locked to the base plate 12, the locking lever 22 is biased to rotate in either the clockwise or counterclockwise direction approximately halfway between the solid line state and the two-dot chain line state. The stoppers 12a, 12
b, and is configured so that it comes to rest in either the solid line state or the two-dot chain line state, and cannot come to rest in the intermediate state.

The right end of the locking lever 22 is connected to the link 6 (FIG. 1) through a hole 22b, and the left end is connected to a key cylinder (not shown) through a hole 22c.

25 is an intermediate lever that is connected to the base plate 12 by a pin 26.
An unlocking lever 28 is pivotally connected to the upper end portion by a pin 27.

Since the pin 27 is independent of the base plate 12, the intermediate lever 25 can rotate about the pin 26.

However, the pole 29 (
(Fig. 4) is installed, and the base plate 12 has a long hole 12.
c is provided to limit the rotation range of the intermediate lever 25.

Please elaborate on this point. Specifically, the pin 26 that makes the intermediate lever 25 rotatable protrudes to the back side in the direction perpendicular to the plane of the paper in FIG. 2, and also makes the pole 29 rotatable as shown in FIG.

On the other hand, a pin 25a is fixed to the intermediate lever 25 in FIG. 2, and the pin 25a protrudes to the back side in the direction perpendicular to the plane of the paper through the elongated hole 12c and is slidably engaged with a hole 29a formed in a pole 29. .

The reason why the pole 29 and pin 25a are drawn with broken lines in FIG. 4 is because they are covered with a cover plate 30.
The cover plate 30 is fixed to the base plate 12 by four bolts 31.

Further, the pole 29 is biased counterclockwise in FIG. 4 by a spring 32.

Due to the above configuration, the intermediate lever 25 is connected to the pin 2.
Even though it can be rotated around 6, it is limited to the range of the length of the elongated hole 12c.

If the lever 25 rotates within the range, the pin 25a,
The pole 29 can also be rotated integrally through the hole 29a.

Reference numeral 25b in FIG. 2 denotes a bent portion that protrudes toward the front side in the direction perpendicular to the plane of the paper, and can come into contact with the lower end of the intermediate link 18 when it moves downward. It is designed to be able to rotate around 26.

28a indicates one end of the unlocking lever 28, and 28b similarly indicates the other end.

The other end 28b is clamped and engaged with the U-shaped groove 11a (FIG. 3) provided in the bell crank 11 described above.

33 is a pin for enabling the bell crank 11 to rotate with respect to the base plate 12, and 34 is a spring whose both ends are locked to the bell crank 11 and the base plate 12, respectively, to perform a snap action similar to the spring 24. This is for producing the crank 11.

11b is a hole for connecting to the link 8 (FIG. 1).

In FIG. 4, a latch 35 is installed so as to be rotatable around a pin 36, and is biased clockwise by a spring 37.

Reference numeral 38 denotes a striker fixed to the vehicle body side of the automobile, and FIG. 4 shows a state in which the door is closed, that is, a closed state.

When the door opens, that is, when the door is in the open state, the striker 38 moves relatively to the left (in the direction of arrow B) in FIG. 4, as will be described later.

Next, the operation of the device of the present invention will be explained.

First, a case will be described in which a closed door as shown in FIG. 4 is opened from the indoor side.

When the inside handle 4 in Fig. 1 is operated, the link 7
The bell crank 10 in FIG. 3 rotates clockwise through the bell crank 10 in FIG. 3, which causes the open lever 15 in FIG. (The protrusion 18 only moves downward relative to the pin 21, and the pin 21 and lever 22 remain stationary.)
c pushes the protruding portion 25b, and the intermediate lever 25 rotates counterclockwise about the pin 26.

This action causes the pawl 29 in FIG. 4 to rotate clockwise against the spring 32 and engage the latch 35 (29b and 35a).
Since the latch 35 is disengaged and rotated clockwise under the action of the spring 37, the strike force 38 moves in the direction B and the door is opened.

Next, when opening the closed door as shown in Fig. 4 from outside the vehicle, actuate the outside handle 3 shown in Fig. 1, the link 5 will be pushed downward as shown in Fig. 2, and the open lever 1
5 rotates counterclockwise, the intermediate lever 25 rotates counterclockwise in exactly the same manner as described above, and the pole 2 shown in FIG.
9 rotates clockwise, and as a result, the striker 38 moves to the left.

Since the figures in Figures 2, 3, and 4 show the unlocked state when the door is closed, we will next explain the operation of the locking button in Figure 1 to obtain the locked state when the door is closed. 2, the link 6 moves upward, and the locking lever 22 rotates counterclockwise through the hole 22b in FIG.

In this state, even if the open lever 15 is rotated counterclockwise in FIG. 2 by actuating either the outside handle 3 or the inside handle 4, the protrusion 18c of the intermediate link 18 will be moved to the protrusion 25b. Since the pole 29 in FIG. 4 cannot be brought into contact with the striker 38 (it is in a swinging state), the pole 29 shown in FIG. 4 cannot be rotated, and therefore the striker 38 cannot be moved in the direction B.

This state, in other words, the state in which the locking lever 22 and intermediate link 18 in FIG. 2 are as shown by the two-dot chain line is the locked state in the closed door state.

In order to obtain the locked state when the door is closed as described above, there is also a method of inserting the key into the key cylinder from outside the vehicle and rotating it. Since the locking lever 22 is rotated counterclockwise through the hole 22c, the locking lever 22 and the intermediate link 18 are in the state shown by the two-dot chain line as described above.

Next, let's talk about the case where the open door is brought into the closed state as shown in Figure 4. In this case, even though the door is in the closed state, there will be an unlocked state in the closed state and a locked state in the closed state, so first of all, Let's start with the former.

In this case, it is assumed that the unlocking lever 28 shown in the second figure is in the two-dot chain line state, and if the door is closed with the locking lever 22 and the intermediate link 18 in the solid line state,
The striker 38 in FIG. 4 moves relatively from the outside in the direction opposite to arrow B and rotates the latch 35 counterclockwise against the spring 37, causing the pawl 29 to rotate and finally the fourth The situation will be as shown in the figure.

Next, in the latter case, that is, when the door is locked in the closed state, by pulling the locking lever 22 and the intermediate link 18, the locking lever 22 and the intermediate link 18 are set to the two-dot chain line, and the door is closed. Therefore, the door will not open regardless of whether the outside handle 3 or the inside handle 4 is operated.

In this case, whether the unlocking lever 28 is in the solid line position or the two-dot chain line position, the locked state is maintained as long as the locking lever 22 is in the two-dot chain line position.

In addition, if such a locking state occurs in the closed state, even if the locking lever 22 remains in the solid line state, as long as the unlocking lever 28 is in the solid line state, when the door is closed, the pawl 26 (fourth 2, the intermediate lever 25 rotates counterclockwise in FIG.
8a will push the protrusion 18a, so the intermediate link 1
8 and the locking lever 22 are both rotated as shown by the two-dot chain line.

Therefore, a locked state also occurs in this case.

The unlocking lever 28 is placed in the two-dot chain line state or in the solid line state by rotating the operating lever 9 shown in FIG. 1 via the bell crank 11.

Next, the effects of the device of the present invention will be explained.

In recent passenger cars, door locks with a so-called "cancelling" function have become commonplace, and this is an excellent feature in preventing the key from being locked inside the vehicle. This is a drawback for careful users.

In other words, even if a careful user removes the key and closes the door, the canceling action will cause the door to become unlocked, and if the door is closed without the locking button being activated, the door will be in the "closed/unlocked" state. However, the "locked state with the door closed" cannot be obtained, and the key must be inserted into the key cylinder from outside the vehicle to lock the door.

This is rather inconvenient for the user, and according to the device of the present invention, if the operating lever 9 in the room is operated and the unlocking lever 28 is set to the solid line position, even if the locking button 2 is operated, it is not possible to operate the locking button 2. Even if you forget to open the door, the door will be reliably locked and the above-mentioned inconvenience can be solved.

Being able to solve the problem in this way also means that it becomes easier to lock the key inside the room, so if the user wants to prevent the key from being locked in, the user can actuate the operating lever 9 in the opposite direction and turn the unlock lever 28. All you have to do is make it a two-dot chain line.

As described above, the device of the present invention is effective in that it can reliably lock the lock or prevent the key from being locked inside the room, depending on the user's preference.
