DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device for an automobile door, and more particularly, to a door lock state (closed state) and a second state lock state. The present invention relates to a door lock device that can operate in three states, a state (locked state) and thirdly, a state in which the closed state is released (released state).

[0002]

2. Description of the Related Art As a door lock device of this type, a lock device body B generally having the above three operation modes is shown in FIG.
Of the door D at the free end D1 for opening and closing. In the conventional example, a knob for performing an operation from the closed holding state to the locked state and an opposite operation, and a lever for performing an operation from the closed holding state to the released state are provided inside the door. And the lock device main body and the knob and lever are connected by individual rods for transmitting the movement of the knob and the lever to the lock device main body B, respectively.

In such a door lock device, since the rod is a rigid body having no elasticity, there are various problems as follows. That is, a rod-shaped object is inserted between the body of the door and the window glass from outside the vehicle, the rod is operated, the lock device is released, the door is opened, and the inside of the vehicle is stolen. point. At the time of a car collision, the rod may bend mechanically, as if the rod were pulled against the lock device body, and the door would be opened in the released state, which could put people in the vehicle at risk Problems. If a predetermined path on which the rod is to be placed is bent in a door of an automobile, it is difficult to dispose the rod on the predetermined path when assembling the locking device to the door, which impairs the workability of the assembly. point. At the time of assembling the lock device to the door, the positional relationship between the lock device main body and the knobs and levers is required to have dimensional accuracy, and at least four problems, such as the need for careful assembly and time-consuming work, are required. There is a problem.

[0004] In order to solve the above-mentioned various problems, there is one configured as follows. That is, in the lock device main body, the operation member for performing the switching operation between the closed holding state, the locked state, and the release state can be freely switched between three positions of an unlock position, a lock position, and a release position. Prepare. In the main body, the locking member for locking the latch member for fitting to the striker and the operating member are such that the latch member is unlocked by the locking member when the operating member is in the release position. When the operating member is in the other position, the latch member is linked to the latch. Also, the locking lever for switching between the unlocked state and the locked state of the door lock device and the operating member are such that when the operating member is in the locked position, the locking lever is in the locked state, and the operating member is in another position. In the state, the locking lever is connected so as to be in the unlocked state. On the other hand, the inside of the door is provided with an operation handle for switching between the closed holding state, the locked state, and the released state. The operation handle and the operation member of the lock device main body are connected by a flexible cable. Such is provided (see, for example, EP-A-169644).

In the above-mentioned construction, the cable for connecting the lock device main body and the operation handle has flexibility, so that operation with a rod-like object from outside the vehicle cannot be performed.
Therefore, the security against theft is excellent. Further, even if the cable is bent at the time of collision of the automobile, the operation member of the lock device main body is not repositioned. Therefore, there is no danger of the release state, and the safety of the person in the vehicle can be ensured. Further, in assembling the locking device to the door, the cable can be freely bent and arranged,
The assembly can be easily performed, and the positional relationship between the lock device main body and the operation member may be rough, so that the assembly can be easily performed. Further, the above-mentioned cable has many advantages as described above, but is expensive, but since only one cable is required, the cost of parts related to the cable is not so large, and only one cable is required to be assembled. The number of work steps can be reduced accordingly, and there is also an effect that the operation can be performed at relatively low cost.

[0006]

In the door lock device having the above structure, the structure of the link between the operating member and the locking lever in the lock device body is as shown in FIG. That is, the locking lever 161 pivotally attached to the housing 160 is provided with two flanges 162 and 163. An operating member 166 which is operated to advance and retreat by the inner wire 165 of the connecting cable 164 has a disc 1
The disk 167 is disposed between the flanges 162 and 163. A spring 168 for urging the disk 167 toward the flange 163 with respect to the locking lever 161 is interposed between the flange 162 and the disk 167. Incidentally, reference numeral 169 in the operation member 166 is a connecting portion with the locking member.

In the above configuration, when the locking lever 161 is in the unlocked state (the closed holding state) shown by a solid line (the closed holding state), the wire 165 is connected to the locking state (the locked state) in the figure. When pushed downward, the flange 163 is pushed by the disk 167, and the locking lever 161 moves to the position shown by the two-dot chain line, and is locked. Pulling the wire 165 in the opposite direction from the locked state,
The flange 162 is pushed by the disc 167 via the spring 168, and the disk 167 is unlocked again. When the wire 165 is further pulled from the unlocked state to the released state, only the spring 168 is compressed and contracted by the disk 167, the locking lever 161 is not displaced, and the unlocking of the locking member is released by the movement of the connecting portion 169. Done.

In such a structure, in the case of the release operation, a total force of a force for unlocking the locking member and a force for compressing and retracting the spring 168 must be applied to the operation handle. However, there is a problem that the operation force of the operation handle is heavy. On the other hand, if the force of the spring 168 is weakened to reduce the operating force, and the movement of the locking lever 161 becomes heavy due to rusting or icing due to aging, the operating handle is operated to unlock from the above locked state. Even if it is operated, there is a problem that the spring 168 contracts while the locking lever 161 is fixed at the position indicated by the two-dot chain line, and the locked state cannot be released. It is very convenient to control three operations of the lock position, the unlock position, and the release position with one handle. However, sometimes the driver intends to move from the locked position to the unlocked position while the vehicle is slowing down just before stopping, and when the handle is operated, the handle may be pulled up continuously until the release position is accidentally reached. . Then there is a danger that the car door will open during slowing down.

[0009] The door lock device of the present application is provided to solve the above-mentioned problems of the prior art.
An object of the present invention is to provide a door lock device that can be operated to achieve the three modes of the closed holding state, the locked state, and the released state. In addition, the operation handle and the lock device main body can be connected by a cable, so that the theft can be prevented, the safety in the event of a collision, and the ease of assembling to the door can be achieved. Furthermore, even if a cable is used, only one cable is required, and implementation can be performed at relatively low cost. Further, even if the operation in the above three modes can be performed with one cable, the release operation from the unlocked state can be performed with a relatively light operation force without using a “spring” as in the conventional product. Is to do so. Further, even if the member for switching between the unlocked state and the locked state becomes difficult to move due to rusting or icing due to aging, the above operation can be performed without using a “spring” as in the conventional product. An object of the present invention is to ensure that switching from a locked state to an unlocked state by an operation from a handle can be performed. Still another object is to allow three operations from a lock position, an unlock position, and a release position with one handle, and from the lock position to the unlock position and from the unlock position, It is to be able to change the operation to the release position. Other objects and advantages will be more readily apparent from the drawings and the following description associated therewith.

When the inside locking lever 84 and the outside locking lever 85 are locked, the operation force of the outside open lever 5 is prevented from being transmitted to the locking member 3. And the locking device body B is set in a locked state. The lever 86 has its shaft 113 connected to a pin 113a.
The second arm 77 of the outside open lever 5
Is pivoted to Reference numeral 114 denotes a first arm, which has a long hole 115 exemplified as a connecting portion to the outside locking lever 85, and a connecting piece 109 is located in the long hole 115.
The long hole 115 is formed in a long hole as shown in the figure so as to guide the direction of movement of the control lever 86 when the outside open lever 5 is released. Reference numeral 116 denotes a second arm for linking with the locking member 3, and an engagement piece
A connecting portion 117 for pushing and driving the 51 is provided.

In the above configuration, when the door of the vehicle is closed and the handle 13 of the operating tool C is in the unlocked position, the lock device main body B is unlocked as shown in FIG. is there. That is, the operating member 4 is at the unlock position U, the striker 39 is fitted into the fitting portion 36 of the latch member 2, and the locking claw 43 of the locking member 3 is
38, thereby preventing the clockwise rotation of the latch member 2, the striker 39 is stopped in the state shown in the drawing, and the door is held in a closed state.

When the handle 13 is moved to the lock position as described above, the lock device main body B is locked as shown in FIG. That is, when the wire 7b is pushed by the operation of the handle 13, as shown in FIG.
Moves to the lock position L. During the movement process, the guide surface 63a of the guide portion 63 mechanically pushes the interlocking member 91,
The inside locking lever 84 turns in the direction of arrow 131 to be in a locked state as shown in the figure. The movement of the lever 84 is transmitted to the outside locking lever 85 via the connecting portion 93 and the connecting piece 108, and the lever 85 turns in the direction of arrow 132 to be in the locked state. Further, it is transmitted to the control lever 86 via the lever 85, and the lever 86 rotates in the direction of the arrow 133 to lock, that is, as shown in FIG.
7 comes off the position facing the engagement piece 51.

When the lock device main body B is in the locked state as described above, the locked state of the latch member 2 by the locking member 3 is maintained in the lock device main body B even if the operation tool on the outer surface of the door is released. , The closed state of the door is maintained.
That is, when the operation tool on the outer surface of the door is released, the wire 8b of the cable 8 is pulled as shown by an arrow 135 in FIG. Then, the outside open lever 5 rotates in the arrow 136 direction. Then, the rotation causes the control lever 86
Is moved. However, since the connecting portion 117 does not face the engaging piece 51, the control lever 86 only moves in the direction of arrow 137, and the locking member 3 remains immobile. Therefore, the locking member 3
Holds the latch member 2 in the locked state. The movement of the control lever 86 in the direction of the arrow 137 is guided by the elongated hole 115. When the releasing operation of the operating tool on the outer surface of the door is stopped, the outside open lever 5 is returned to the position shown in FIG.

When the handle 13 is moved to the unlock position again as described above, the lock device main body B is again in the unlock state. That is, by operating the handle 13, the wire
When 7b is pulled, the operating member 4 moves to the unlock position U as shown in FIG. In the process of moving
The guide surface 63b of 63 mechanically pushes the interlocking member 91, and the inside locking lever 84 turns in the direction of arrow 140 to be in the unlocked state as shown in the figure. The movement of the lever 84 is transmitted to the outside locking lever 85 via the connecting portion 93 and the connecting piece 108, and the lever 85 turns in the direction of the arrow 142 to be in the unlocked state. Further, it is transmitted to the control lever 86 via the lever 85, and the lever 86
In the unlocked state, the connecting portion 117 faces the engaging piece 51 as shown in FIG.

In the case of the above-described unlocking operation, the operating force for the unlocking operation applied to the operating member 4 from the wire 7b is applied to the switching means 6 through the engagement between the rigid bodies of the guide surface 63b and the interlocking member 91. Reportedly. Therefore, the switching means 6
Even if the members such as the inside locking lever 84, the outside locking lever 85, and the control lever 86 are frozen or rusted and their movements are deteriorated, the operation force is forcibly applied from the operation member 4 to the lever 84. In addition to this, it can be forcibly operated, and the other levers 85 and 86 can also be forcibly operated in order, so that the unlocked state can be reliably achieved.

When the lock device main body B is in the unlocked state as described above, the lock device main body B is released by operating the operation tool on the outer surface of the door, and the latch member 3 is locked by the locking member 3. It is unlocked and the door can be opened. That is, when the operation tool on the outer surface of the door is released, the wire 8b of the cable 8 is pulled as shown by an arrow 145 in FIG. Then the outside open lever 5 is an arrow
Rotate in 146 directions. Then, the control lever 86 is moved in the direction of arrow 147 by the rotation. By the movement, the connecting portion 117 pushes the engagement piece 51, and the locking member 3
The locking claw 43 is disengaged from the full latch claw 38 by pivoting in the direction.
Then, the latch member 2 can rotate in the direction of the arrow 149, and the striker 39 comes out of the fitting portion 36 as shown by the arrow 150, so that the door of the automobile can be opened.

When the handle 13 is moved to the release position as described above, the lock device body B is released, and the door can be opened. That is, when the wire 7b is further pulled by operating the handle 13, the operation member 4 moves to the release position R as shown in FIG. This movement causes the drive unit 60
Pushes the driven part 49 of the locking member 3 in the direction of the arrow 153 and the locking claw 4
3 comes off the full latch claw 38. As a result, the door can be opened as described above. In the case of this operation, the force required for operating the handle 13 is relatively small enough to detach the locking member 3 from the latch member 2 via the cable 7 and the operating member 4 as described with reference to FIG. Small power is enough. Next, the operating tool C shown in FIGS.
The operation tool C described in FIGS. 16 to 26 was used to explain the basic operation, but was further described in FIGS.
This will be described below using 1. Parts that are considered to have substantially the same function and the same configuration as those of the members in FIGS. 3 to 5 are denoted by the same reference numerals, and redundant description of both will be omitted. FIG.
8, FIG. 22, and FIG. 26 show that the handle 13 is in the “unlocked position”,
This shows the state in the “lock position” and the “release position”. As shown in FIG. 1, the frame 11 has an upper (front) edge 11a embedded so as to be substantially flush with the inner surface of the door D, and a handle 13 is swingably mounted in an inner concave portion 11c. The deep portion 11d having a narrow width in the concave portion 11c causes the main portion 13a at one end of the handle 13 to sink in the locked position, and the occupant's finger F is moved to the main portion as shown in FIG.
It is a concave portion whose periphery is surrounded by a wall so as not to enter the back side of 13a. Therefore, when the wall of the deep portion 11 is wide as shown by the two-dot chain line in the concave portion 11c, instead of forming the deep portion 11d having a small width, the main portion 13a is surrounded by the lock position,
On the both sides, another blocking member for preventing insertion of the finger F may be arranged in an erect manner to form the surrounding position 11d. FIG.
In, the wall member denoted by reference numeral 11e serves as a blocking member. In the recess 11c, the space 11f corresponds to the handle 13 shown in FIG.
8 is in the unlock position, as shown in FIG.
This is an open space formed so that the wall does not come close to the periphery so that the finger F can be easily inserted into the back side of a. Recess 11c
The space 11g is provided with an auxiliary portion 13b at the other end of the handle 13 as shown in FIG.
It is a space for sinking at the release position as shown in 6. When the auxiliary portion 13b is in the lock position shown in FIG.
Floating at 1k, but around the side wall of frame 11
11a exists. If necessary, a part 11b of the upper edge of the side wall is made to correspond to the floating amount of the auxiliary part 13b in FIGS.
As shown in FIG. 2, a cover having a through hole enough to allow a finger to enter the auxiliary portion 13b may be provided. In this way, the auxiliary portion 13b can prevent the state of FIG. 18 from changing to the state of FIG. 18 even if the occupant's body covers the locked position in FIG. Note that the fulcrum 14 of the handle 13 is distributed so that the main part 13a is long and the auxiliary part 13b is short, for example, 2: 1 so that a large operating force can be exerted on the main part 13a. It is also possible to make it heavy so that it cannot be done. Therefore, it is limited that the handle 13 can be moved from the locked position to the unlocked position even with the finger pressure of an adult, and cannot be pushed deeper than that. If necessary, the auxiliary portion 13b may be configured so that it cannot be pushed by a finger from the position shown in FIG. That is, space 11g
The width W of the lower side wall is preferably smaller than the thickness of the finger as shown by a two-dot chain line 11m in FIG. In this case, it is preferable that the width of the other end 13b of the handle is also relatively narrow as shown by a two-dot chain line 13g in FIG.

In the above configuration, the functions similar to those described with reference to FIGS. 3 to 5 are exerted by the operation between FIGS. 18, 22 and 26. When the handle 13 is in the unlocked position in FIG. 18 and the main part 13a is pushed in the direction of the arrow, that is, in the pushing direction, the state shown in FIG. 22 is obtained, and the periphery is surrounded and the main part 13a is Can not be picked or pulled out. However, the main part 13a is the auxiliary part 1 at the other end.
Since 3b is at the floating position 11k where it can float and be pressed,
When this is operated in the direction of the arrow in the state of FIG. 22, that is, in the direction of being pushed by an adult's finger toward the recess 11g, it returns as shown in FIG. 18 and becomes the unlock position. Next, in order to set the handle 13 to the release position, the handle 13 is in the open position 11f and its periphery is open, so that the main part 13a is again pulled with the finger F as shown in FIG. Then Figure 2
6. The release position is reached as shown in FIG. As described above, by moving one handle 13 to the three positions of the unlock position, the lock position, and the release position, the lock device main body B can be operated in the corresponding closed holding state, the lock state, and the release state as described above. Even with this configuration, the handle operation is performed by pushing the main part 13a from the unlock position to the lock position, pushing the auxiliary part 13b from the lock position to the unlock position, and From the position to the release position, the operation of raising the main portion 13a and the operation are successively different in all three modes.

[0039]

As described above, according to the present invention, the operating member 4 enabling the position change between the unlock position U, the lock position L and the release position R is connected to the locking member 3 and the switching means 6. Because of this, there is an effect that the above three operations of the closed holding state, the locked state, and the released state can be performed only by operating the operation member 4. This means that, for example, by connecting the operation member 4 to the operation handle with a single cable, prevention of the theft, safety in the event of a collision, and ease of assembling to the door can be achieved. Even if a cable is used, only one cable is required, and the method can be implemented at relatively low cost. Moreover, even when the operation in the above three modes is possible with one cable, when the release operation is performed from the unlocked state, the operation member 4 is moved to the unlock position U.
From the release member R to the release position R, the operation is transmitted to the locking member 3, but is not transmitted to the switching means 6 by the presence of the release portion 64. It only has to be moved with enough force to release the lock of 2,
The release operation from the unlocked state can be performed with a relatively light operation force. Further, the operating member 4 and the switching means 6 are connected to each other by the guide member 63 provided on the operating member 4 pushing the interlocking member 91 provided on the switching means 6 so that the operating member 4 is unlocked and locked at the locking position U and the locking position L. The switching means 6 is switched between the unlocked state and the locked state in the process of moving between them, so that even if the switching means 6 becomes uncomfortable due to icing or rusting, the switching means 6 can be used as in the conventional product. There is an effect that the switching means 6 can be surely switched by operating the operation member 4 without using a “spring”.

Further, in the present invention, the handle (13)
One end on the side which becomes the main part (13a) of the frame (11f) is in an unlocked position and a release position, in which the periphery of the frame (11) is open so that the occupant can operate with his / her finger on the frame (11).
In the lock position, the swing range is determined so as to be located at a deep surrounding position (11d) where the surroundings are surrounded so that the occupant is difficult to operate with a finger on the frame (11),
The other end (13b) of the handle (13) floats near the outer edge (11a) of the frame in the locked position, and is located at a position (11k) at which a pressing operation for pushing with a passenger's finger is possible. As a result, the main portion 13a of the handle has a feature that the periphery thereof is surrounded in the locked position, and the operation thereof requires a pushing operation of the auxiliary portion 13b at the other end. Therefore, even if one handle controls three modes, it is possible to interrupt the continuous operability of transition from the lock position to the unlock position and from the unlock position to the release position. It is useful for preventing accidents such as the conventional example.
