Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a locking device for an opening/closing member in a vehicle.

2. Description of the Related Art Vehicle bodies are provided with opening/closing members such as trunk lids, back doors, and hoods equipped with locking devices. This locking device is configured so that it can be unlocked from outside the vehicle using a key, and can also be unlocked from inside the vehicle without a key. Since the lock can be unlocked from inside the vehicle, there is a risk that the lock device may be unlocked inadvertently. For example, if the driver leaves the vehicle without locking the doors, a third party may enter the vehicle and unlock the lock device.

Therefore, unlocking from inside the car is prohibited as necessary.
That is, a lock device configured to allow cancellation has been proposed.

FIG. 7 shows an example of a conventional locking device of this type. In this locking device, a rotating member 13a, a latch member 3a, a cancel member 11a, and an actuating member 12a are rotatably supported on a base member 1a fixed to an opening/closing member such as a trunk lid, and the opening/closing member is in a locked state. 7, the rotating member 13a and the locking member 3a engage with each other, and the striker 40a fixed to the vehicle body 41a is locked by the locking member 3a. There is.

To release the lock from inside the vehicle, use rotating member 1.
The wire 28a connected to the hook 3a is pulled, and the rotating member 13a rotates as shown by the chain line, and the engagement between the rotating member 13a and the locking member 3a is released. As a result, the locking member 3a is rotated as shown by a chain line by a spring (not shown), and the restraint of the striker 40a is released. Therefore, the opening/closing member can be opened freely. Further, by operating a cylinder lock (not shown) from outside the vehicle, the operating member 12a is rotated as shown by the chain line, and the rotating member 13a is rotated to the position shown by the chain line, thereby similarly releasing the lock of the opening/closing member.

Operating member 1 by operating the cylinder lock above from outside the vehicle.
When 2a is rotated clockwise, a projection (not shown) attached thereto presses the cancel member 11a clockwise, and the member 11a engages with the locking member 3a as shown in FIG. Rotation of the locking member 3a is prohibited. Therefore, even if the wire 28a is operated from inside the vehicle and the rotating member 13a is rotated to the position indicated by the chain line, the latching member 3a does not operate and the striker 40
Maintain the restraint state to a. This is a cancel operation, which eliminates the possibility that the opening/closing member will be opened unnecessarily.

As mentioned above, the locking device shown in FIGS. 7 and 8 has excellent advantages such as reliable canceling operation and simple structure. However, since the cancel member 11a is configured to prohibit the operation of the locking member 3a during the cancel operation, due to manufacturing errors of the locking device, the cancel member 11a and the locking member 3a engaged with the locking member 3a may When a slight gap is created between the rotating member 13a and the
When the latching member 3a is rotated, the latching member 3a
Due to the spring force, it rotates slightly as shown by the broken line. When such a situation occurs, the rotating member 13
When a rotates clockwise to return to the position shown by the solid line, its claw portion hits the hooking member 3a shown by the broken line, and there is a risk that the two will not engage properly. In order to eliminate such problems, it is possible to improve the dimensional accuracy of the parts of the locking device and their assembly accuracy to avoid the above-mentioned gaps. However, if the device is manufactured with high precision in this way, This has the disadvantage of increasing costs.

Purpose The purpose of the present invention is to provide a locking device that can eliminate the above-mentioned conventional drawbacks and reduce costs.

Configuration In order to achieve the above object, the present invention includes a base member attached to a vehicle body or an opening/closing member pivotally connected to the vehicle body, and a base member rotatably supported by the base member via a pivot pin and provided on the inside of the vehicle. a rotation member that is rotatably operated by the pivot pin; a cancel member that is rotatably supported by the pivot pin and rotated by an operation from outside the vehicle; and a cancel member that is rotatably supported by the pivot pin and other than the pivot pin. a force transmitting member that is pivotally connected to the cancel member via a connecting pin and rotates around the pivot pin as the cancel member rotates around the pivot pin; and the base member. a striker attached to a vehicle body or an opening/closing member that is not connected to the vehicle; and a striker rotatably supported by the base member so as to be able to engage with or disengage from the striker, and detach from the striker by rotation of the force transmission member. a locking member that rotates in a direction, and the cancel member has a long hole formed in the member that fits into the pivot pin, and is rotatably supported with respect to the pivot pin. , by sliding the elongated hole relative to the pivot pin by operation from outside the vehicle, when the rotating member rotates, the first member is pressed by the rotating member and rotates together with the rotating member. and a second position where the rotating member does not come into contact with the rotating member and receives no force from the rotating member when the rotating member rotates, around the connecting pin. A locking device for an opening/closing member in a vehicle is proposed.

Embodiment Hereinafter, an embodiment configured as a locking device for a trunk lid, which is an example of an opening/closing member in a vehicle, will be described with reference to the drawings.

1 to 3, a base member 1 having a generally inverted U-shaped cutout 2 in its lower part is fixed to a trunk lid (not shown) of a vehicle, for example a trunk lid (not shown) which is pivotally mounted to the rear of a passenger's vehicle. A latching member 3 and a regulating member 4 for regulating the operation of the latching member 3 are rotatably attached to the base member 1 near the notch 2 by pins 5 and 6, respectively. Parts 3 and 4
are given the tendency to rotate in the direction toward each other by a tension spring 7 which is engaged with these.

A claw portion 8 formed at one end of the locking member 3 can protrude into the notch 2 of the base member 1 or retreat from the notch 2, and a protrusion 8a provided at the other end of the locking member 3 , can be engaged with and disengaged from the stepped portion 9 of the regulating member 4.

A pivot pin 1 fixed to a substantially central region of the base member 1
0, a cancel member 11, a force transmitting member 12 that transmits an operating force (described later) to the regulating member 4, and a rotating member 13 are rotatably supported. that time,
A pivot pin 10 fits into a long hole 14 formed in the cancel member 11, and the cancel member 11 is slidable relative to the pin 10 (see FIGS. 4 to 6).

As can be seen from FIGS. 4 to 6, the cancel member 11 has first to fourth arm portions 1 that respectively project outward about the region of the pivot pin 10.
5, 16, 17, 18, and similarly the force transmitting member 12 has first and second pins extending outwardly from the pivot pin 10.
It has arm parts 19 and 20 and a third arm part 21 that further protrudes from the second arm part 20.

One end of an operating link 22 is pivotally connected to the first arm portion 15 of the cancel member 11 by a coupling member 23, and the other end is connected to a rotor of a cylinder lock (both not shown) operated from outside the vehicle and attached to the trunk lid. is connected to.

The second arm portion 16 of the cancel member 11 is provided with a protrusion 24 that protrudes toward the front side of the page in FIG. 4, and the cancel member 11 occupies the first position shown in FIGS. 1 and 4. When the rotating member 13 is rotated counterclockwise from the position shown in FIG. 1, the protrusion 24 and the contact portion 25 of the rotating member 13 can come into contact with each other. On the other hand, the cancel member 11 is in the second position shown in FIGS. 5 and 6.
Even if the rotating member 1
3 rotates, its contact portion 25 does not come into contact with the protrusion 24 of the cancel member 11.

The third arm portion 17 of the cancel member 11 is pivotally connected to the second arm portion 20 of the force transmitting member 12 by a connecting pin 26 . In this way, the cancel member 11 is supported such that the elongated hole 14 formed in the member 11 fits into the pivot pin 10 and is rotatable relative to the pin, and the cancel member 11 can be moved between the first position and the first position. 2
It is supported so as to be rotatable about the connecting pin 26 between the two positions. Cancel member 1
Each end of a torsion coil spring 27 is locked to the fourth arm portion 18 of the force transmitting member 1 and the third arm portion 21 of the force transmitting member 12, respectively. Further, the tip of the first arm portion 19 of the force transmitting member 12 is adapted to come into contact with the tip of the regulating member 4 and press the member 4, as shown in FIG. As described above, the force transmitting member 12 rotatably supported by the base member 1 via the pivot pin 10 has a cancel member 11 at a location other than the pivot pin 10, that is, at its arm portion 20.
are pivotally connected via a connecting pin 26.

In FIG. 1 and FIGS. 4 to 6, the opener handle on the driver's seat side in the vehicle (not shown) and the rotating member 13 are connected by a wire 28. One end of the wire 28 passes through a groove 31 formed in the rising flange 30 of the rotating member 13, and a locking ball 29 provided on the wire 28 is inserted into the flange 30.
By engaging with the wire 28 and the rotating member 1
3 are connected (Fig. 6). The other end of wire 28 is connected to the opener handle in a known manner.
32 is a tube-shaped wire guide fixed to the flange 33 of the base member 1, and the wire 28 is movably inserted through the tube-shaped wire guide. Further, the rotating member 13 is given rotational sliding property in the clockwise direction in FIG. When not in operation, the member 13 is held in the position shown in FIG. 1 by contacting a stopper (not shown). Furthermore, as shown in FIGS. 1 and 3, a U-shaped striker 40 is fixed to the vehicle body 41.

The illustrated locking device is generally constructed as described above, and its operation is as follows.

When the trunk lid (not shown) is closed and locked, and the locking device can be unlocked from inside the vehicle, each element of the locking device is
It is stationary in the state shown in the figure. That is, the hanging member 3
The protrusion 8a and the stepped portion 9 of the regulating member 4 engage with each other, and the locking member 3 is fixedly locked. At this time, the claw portion 8 of the locking member 3 protrudes into the cutout 2 of the base member 1, and the locking member 3 is fixedly locked. 2
The tip 40a of the striker 40 is inserted into the area.
Also, the striker 40 engages with the pawl 8, and the base member 1 and therefore the trunk lid are locked with respect to the vehicle body 41. The cancel member 11 occupies a first position and is prevented from moving from this first position towards the second position by the action of the torsion coil spring 27. The states of the other elements are also clear from FIG.

When attempting to open the trunk lid by operating from outside the vehicle, a key (not shown) is inserted into the cylinder lock and the rotor is rotated.
As a result, the operating link 22 is pushed downward in FIG.
0 in the counterclockwise direction in FIG. 1 and brought to the position shown in FIG. 4. Even after its rotation, the cancel member 11 occupies the first position due to the action of the torsion coil spring 27. Therefore, if the rotation member 13 rotates at this time, the contact portion 2
5 can come into contact with the protrusion 24 of the cancel member 11. By operating the cylinder lock and the operating link 22 in this way, the cancel member 11 can be operated from outside the vehicle.

When the cancel member 11 rotates counterclockwise as described above, the force transmitting member 1 pivotally connected to the cancel member 11
2 also rotates counterclockwise with respect to the base member 1 around the pivot pin 10 due to the rotation of the cancel member. At this time, the first arm portion 19 of the force transmission member 12
The tip presses the tip of the regulating member 4 (FIGS. 1 and 3), thereby causing the regulating member 4 to rotate around the pin 6 in the clockwise direction in FIG. 3. Along with this, the locking member 3 also connects the regulating member 4 via the spring 7.
However, while the projection 8a and step 9 are engaged with each other, rotation of the locking member 3 is prevented. When the engagement between the protrusion 8a and the stepped portion 9 is released, the locking member 3 is rotated clockwise by the tensile force from the spring 7, and the claw portion 8 is rotated as shown by the chain line in FIG. As shown, it retreats from the notch 2 of the base member 1. As described above, due to the rotation of the force transmission member 12 accompanying the rotation of the cancel member 11, the latch member 3 is operated in the direction of detaching from the striker 40, and the claw portion 8
The engaged state of the striker 40 and the locked state of the trunk lid or the locking device are released, and the trunk lid can be opened freely. This is an unlocking operation performed from outside the vehicle, and during this operation, the rotating member 13 remains stationary without any operation.

On the other hand, when the opener handle is operated from the driver's seat inside the vehicle and the wire 28 is pulled in the direction of arrow A, the rotating member 1 connected to the wire 28 via the locking ball 29
3 rotates counterclockwise around the pivot pin 10 from the position shown in FIG.
The protrusion 2 of the cancel member 11 occupies the position of
4 and press it, cancel member 11
rotates together with the rotating member 13 to the position shown in FIG. Therefore, just as in the case of a lock release operation from outside the vehicle, the cancel member 11 rotates in the same direction as the rotation direction when the operating link 22 is pressed down, and the force transmitting member 12, the regulating member 4, and the locking member 3 are rotated.
is activated, the engagement between the striker 40 and the claw portion 8 is released, and the locked state of the trunk lid or the locking device is released.

To close the trunk lid once opened, simply press it against the vehicle body.
As a result, the tip 40a of the striker 40 that has entered the notch 2 of the base member 1 hits the protrusion 8a of the latching member 3, and the latching member 3 rotates counterclockwise in FIG. is the claw part 8
At the same time, the regulating member 4 is pulled by the spring 7 and rotates counterclockwise, so that the protrusion 8a and the stepped portion 9 engage with each other. Along with this, each of the other elements is also returned to the initial state shown in FIG.

As described above, the lock device can be unlocked both from outside the vehicle and from inside the vehicle, and its operation can be greatly simplified. However, if we were to make it possible to release the lock device completely from inside the car,
As described above, since there is a risk that the lock device may be unlocked involuntarily, unlocking from inside the vehicle can be prohibited (cancelled) by the cancel member 11 as necessary. The operation will be explained below.

When trying to prohibit unlocking from inside the car,
Insert the key into the aforementioned cylinder lock and rotate the rotor. At this time, the rotor is rotated in the opposite direction to the previously described unlocking operation of the lock device from outside the vehicle, and the operating link 22 is operated upward from the position shown in FIG. As a result, the cancel member 1
1 is rotated clockwise in FIG. 1 around a connecting pin 26 that pivotally connects the member 11 and the force transmitting member 12, and is brought to the second position shown in FIG. At this time, since the pivot pin 10 is fitted into the long hole 14 of the cancel member 11, this long hole 14 slides on the pivot pin 10, and the cancel member 10 is moved by a distance corresponding to the length of the long hole 14. can move upwards. When the cancel member 11 reaches the second position, the torsion coil spring 27 now acts to hold the member 11 in its second position. Further, even if the cancel member 11 is operated as described above, the force transmitting member 12 is not operated and remains stationary.

When the opener handle is operated from inside the vehicle in the above-mentioned state and the wire 28 is pulled in the direction of arrow A, the rotating member 13 rotates counterclockwise from the position shown in FIG. 5 in the same way as when unlocking from inside the vehicle. move. However, in this case, since the cancel member 11 is held in the second position, the contact portion 25 of the rotating member 13 does not come into contact with the protrusion 24 of the cancel member 11, and therefore, the cancel member 11 is not rotated. No force is transmitted from the moving member 13, only the rotating member 13 rotates, and the cancel member 11 does not rotate (6th
figure). Therefore, the force transmitting member 12 does not rotate, and the locking member 3 maintains the state shown in FIG. 1, so that the engagement between the striker 40 and the claw portion 8 is not released. In this way, even if the opener handle is operated from inside the vehicle, the trunk lid will not be unlocked, so there is no possibility that a third party who has entered the vehicle will open the trunk. Also, when the rotating member 13 rotates back clockwise from the position shown in FIG. 6 due to the action of the spring 34, the cancel member 11
occupies the second position, the rotating member 13 has its contact portion 25 contacting the projection 24 of the canceling member 11.
It is possible to reliably return to the position shown in FIG. 5 without hitting, that is, while spinning idly.

Furthermore, if you use a special key for the trunk lid, separate from the engine key, as the key to operate the cylinder lock mentioned above, even if the engine key falls into the hands of another person, you will not have to carry the key for the trunk lid yourself. As long as you are there, there is no fear that someone else will open your trunk.

As described above, according to the locking device according to the embodiment of the present invention, during the normal unlocking operation of the trunk lid, the cancel member 11 itself is rotated to operate the locking member 3, and during the cancel operation, the cancel member 11 is moved to the second position. By bringing the rotating member 13 to the position shown in FIG. 1, even if the rotating member 13 is rotated by an operation from inside the vehicle, the member 13 will idle relative to the cancel member 11, and the cancel member 11 will not be pressed and rotated, thereby maintaining the locked state. maintain. Even when rotating the rotating member 13 back, the cancel member 11
It spins idly against the object and returns to its original position without any trouble. That is, unlike conventional locking devices, the locked state is not maintained by prohibiting the locking member from operating using a cancel member. Therefore, in the lock device according to the present invention, there is no problem with the gap between the cancel member and the latching member during the cancel operation, and the dimensional accuracy and assembly accuracy of each part can be improved compared to the conventional lock device. Even if the accuracy is not as high as that, there is no problem with the operation and the cost can be reduced.

Although advantageous embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be modified in various ways. For example, in the above embodiment, the base member and various other elements attached thereto were provided on the trunk lid side, and the striker was provided on the vehicle body side, but conversely, the base member was provided on the vehicle body side, and the striker was provided on the trunk lid side. You can. Further, in the illustrated embodiment, a cylinder lock and an operating link 22 are used as operating means for operating the cancel member from the outside of the vehicle to the first position or the second position or for rotating the cancel member. Alternatively, an actuating member such as a cam or wire may be used in place of the actuating link, or the lock and cancel member may be connected substantially directly without the use of such an actuating member. Also, instead of transmitting the force from the force transmitting member to the latching member via the regulating member, the regulating member is omitted and the force is directly transmitted from the force transmitting member to the latching member. It is also possible. Further, instead of using the wire 28 as the operating means for rotating the rotating member from the seat of the vehicle, any suitable means such as a linkage, an actuating rod, a magnet, or an electric motor may be used.

Of course, the present invention can be implemented not only as a locking device for a trunk lid but also as a locking device for other opening/closing members, such as a back door or a hood.

Effects of the invention As described above, according to the invention, the gap between the locking member and the cancel member engaged therewith, unlike in conventional locking devices, must be eliminated or minimized. There is no need to pay any consideration to this, making it possible to reduce the cost of the lock device.
