(Problems to be solved by the invention)
Incidentally, in the double lock type vehicle door lock device described in Patent Document 1 described above, the lock lever capable of switching the active lever of the lock mechanism between the lock position and the unlock position is provided with the lock operation lever and the cover. A latching lever is provided, and the latched lever is formed of a linear spring steel material, and is configured to be detachable from the latching lever (double lock lever). An inside open lever that can be linked to the lock lever includes a first inside lever and a second inside lever.

  For this reason, the double lock type vehicle door lock device described in Patent Document 1 described above can be a normal lock type door lock device by removing the latch lever (double lock lever). . However, in the normal lock specification door lock device with such a configuration, the lock lever that has no functional problem even if it consists of a single part has a complicated structure (normal lock specification) with a lock operation lever and a latching lever. The door lock device has an unnecessary function). Therefore, the double lock type vehicle door lock device described in Patent Document 1 described above includes components used in a double lock type door lock device including a double lock mechanism and a double lock mechanism. It is difficult to share the parts used in the normal lock specification door lock device with a simple configuration.

  Moreover, in the double lock type vehicle door lock device described in Patent Document 1 described above, when in the double lock state, for example, a lock knob or an inside open lever linked to the lock operation lever of the lock lever is illegal from the outside of the vehicle. The active lever is held in the locked position and does not move even if it is operated (attacked from outside). For this reason, although the advantage of preventing unauthorized unlocking is obtained, the active lever does not move, so the position switch attached to the active lever (usually provided for detecting lock / unlock) Cannot be used to detect the attack described above.

(Means for solving the problem)
The present invention has been made to solve the above problems,
A latch mechanism capable of holding the vehicle door closed with respect to the body, and being assembled to the door together with the housing;
An inside open lever that is rotatably assembled to the housing and is driven to rotate from an initial position to an operating position in accordance with a door opening operation of an inside door handle provided inside the door;
An outside open lever that is rotatably assembled to the housing and is driven to rotate from an initial position to an operating position in accordance with a door opening operation of an outside door handle provided outside the door;
The connecting portion that is displaced in accordance with the rotation of the outside open lever is assembled so as to be tiltable by a predetermined amount, and has a pushing portion that can be engaged with an engaging portion of a lift lever provided in the latch mechanism. An open link that is pushed from the initial position toward the lift lever at the time of rotational driving from the initial position of the inside open lever to the operating position or at the time of rotational driving from the initial position of the outside open lever to the operating position;
A lock mechanism capable of switching the open link to an unlocked state capable of being linked to the lift lever or a locked state not linked to the lift lever;
A door lock device for a double lock type vehicle having a double lock mechanism that can be switched to a double lock state in which the door lock state by the lock mechanism cannot be released or an undouble lock state in which the double lock state is released. ,
The locking mechanism is rotatably assembled to the housing, and is switched from the unlocked position to the locked position by the locking operation of the locking / unlocking operation member to bring the open link into the locked state. An active lever that is switched from a locked position to an unlocked position by an unlocking operation to bring the open link into the unlocked state;
The double lock mechanism is movably assembled to the housing, and is switched from an unset position to a set position by a set operation of a double lock operation member, and is opposed to the open link so as to be engageable with the open link. The movement from the locked state to the unlocked state is prevented, and the double-lock operation member is switched from the set position to the unset position by the unset operation to move away from the open link to change from the open link locked state to the unlocked state. It is characterized by having a double lock lever that allows movement of the

  In this case, the double lock lever is assembled so as to be movable along a guide provided in the housing. When the double lock lever is in the set position, the lower end of the double lock lever is an engagement arm formed on the open link. It is also possible to face the part in close proximity.

In these cases,
The open link is interposed between the outside open lever and the open link, and biases the open link toward the unlocked state to allow the open link to return to the initial position. A spring to be held relatively movable with respect to,
An unlock holding guide for holding the open link in an unlocked state when the active lever is in the unlocked position and the outside open lever rotates between an initial position and an operating position;
A lock holding guide for holding the open link in a locked state when the active lever is in a locked position and the outside open lever rotates between an initial position and an operating position;
When the active lever is in the unlocked position, the open link is tilted by switching the unlocked position of the active lever to the locked position when the active lever is in the unlocked position. And a push arm portion that is detachable from the open link so as to allow the open link to engage with the open link and allow the open link to move to the unlocked state. It is also possible.

(Effects of the invention)
In the double lock type vehicle door lock device according to the present invention, the double lock mechanism linked to the open link and the component parts other than the component parts for switching the double lock lever between the unset position and the set position are the double lock mechanism. It is the same as the component used in the door lock device of the normal lock specification which is not equipped with. For this reason, the components other than the double lock mechanism used in the double lock specification door lock device and the components used in the normal lock specification door lock device not equipped with the double lock mechanism are shared. These two door lock devices can be manufactured at low cost.

  Further, in the double lock type vehicle door lock device according to the present invention, the double lock lever is assembled to the housing, and the open link is switched from the unset position to the set position by the setting operation of the double lock operating member. It is comprised so that it may engage with. For this reason, when the lock lever is linked to the active lever in the locked position in the double-locked state, for example, when the lock knob is illegally unlocked from the outside (attack from the outside), the active lever switches from the locked position to the unlocked position. However, the double lock lever is maintained in the set position and engages with the open link to prevent the open link from moving from the locked state to the unlocked state.

  Therefore, the open link is held in a locked state, and unauthorized unlocking can be prevented. At this time, since the active lever is switched from the locked position to the unlocked position by an unauthorized operation (external attack) from outside the vehicle, the position switch attached to the active lever (usually for detecting lock / unlock) It is also possible to detect the above-described attack (attack detection by a position switch) by the operation of (provided).

  Further, when the above-described present invention is carried out, the double lock lever is assembled so as to be movable along a guide provided in the housing, and when the double lock lever is in the set position, the lower end portion thereof becomes the open link. When configured so as to be close to and opposed to the formed engagement arm portion, the double lock lever can be implemented with a simple bar-shaped configuration, and the occupied space in the housing may be small, and the door lock device Contributes to downsizing.

  Further, when the door lock device includes the above-described spring, the above-described unlock holding guide, the above-described lock holding guide, and the above-described push arm portion in the implementation of the above-described present invention, A spring interposed between the outside open lever and the open link urges the open link toward the unlocked state, and allows the open link to return to the initial position of the open link. It is held so as to be movable relative to the lift lever. In addition, the push arm portion of the active lever can be detached from the open link so as to allow the open link in the locked state to move to the unlocked state. For this reason, when the door handle and the locking / unlocking operation member are operated at the same time in the door lock state (the door locked state), the open link is held to be movable relative to the lift lever. Return to the initial position is allowed. Therefore, even in the panic state described above, returning the outside open lever to the initial position returns the open link to the initial position while being in the unlocked state, and switches to the door unlocked state (the door unlocked state). Can be carried out smoothly.

  In this case, when the panic state occurs as described above, the spring interposed between the outside open lever and the open link functions as described above. It is possible to configure the active lever as a single member. Therefore, the components from the active lever to the open link can be made into three components such as an active lever, a spring, and an open link, and can be configured simply and inexpensively. Therefore, the components with a simple configuration (parts that do not have useless functions) that are used in the normal lock type door lock device without a double lock mechanism are used in the double lock type door lock device. It is possible to manufacture these both door lock devices simply and inexpensively in common with components other than the double lock mechanism.

When the door is closed with the side door handle opened, (g) the double lock operating member is set in the door locked state. , Each component operates as follows.

“(A) Operation when the inside door handle is opened with the door unlocked”
When the double-lock type vehicle door lock device 100 is in the door unlocked state as shown in FIGS. 1 to 4 with the door closed, the inside door is operated along with the door opening operation of the inside door handle (not shown). When the open lever 21 is operated in the door opening direction (clockwise rotation direction in FIG. 2), the open link 23 in the unlocked state is pushed by the inside open lever 21 as shown in FIGS. 4 and 5. The open lever 22 is moved from the initial position (position in FIG. 4) to the operating position in FIG. 5, and the lift lever 12 rotates in the unlatching direction (clockwise direction in FIG. 4). Therefore, the door opening direction operation of the inside open lever 21 is transmitted to the lift lever 12 via the outside open lever 22 and the open link 23, the lift lever 12 rotates in the unlatching direction, and the latch mechanism 10 is moved from the latched state. It becomes an unlatched state and the door can be opened.

“(B) Operation when the outside door handle is opened by door unlocking”
Further, when the door is closed and the double lock type vehicle door lock device 100 is in the unlocked state as shown in FIGS. 1 to 4, the door opening operation of the outside door handle (not shown) is accompanied. When the outside open lever 22 is actuated in the door opening direction (clockwise rotation in FIG. 4), the open link 23 in the unlocked state is moved to the initial position by the outside open lever 22, as shown in FIGS. The lift lever 12 rotates in the unlatching direction by being moved from the position shown in FIG. 4 to the operating position shown in FIG. Therefore, the door opening direction operation of the outside open lever 22 is transmitted to the lift lever 12 via the open link 23, the lift lever 12 rotates in the unlatching direction, and the latch mechanism 10 changes from the latched state to the unlatched state. Can be opened.

"(C) Operation when the outside door handle is operated to open the door with the door locked"
Further, when the double-lock type vehicle door lock device 100 is in the door-locked state as shown in FIGS. 6 and 7 with the door closed, accompanying the door opening operation of the outside door handle (not shown). When the outside open lever 22 operates in the door opening direction, the open link 23 in the locked state shown in FIG. 7 is lifted while being guided by the lock holding guide 25a provided in the active lever 25 in the locked state shown in FIG. Thus, the lift lever 12 is not engaged. Therefore, the operation of the outside open lever 22 in the door opening direction is not transmitted to the lift lever 12, the lift lever 12 does not rotate, the latch mechanism 10 is maintained in the latched state, and the door cannot be opened.

“(D) Operation when opening the inside door handle with the door locked”
On the other hand, when the double-lock type vehicle door lock device 100 is in the door-locked state as shown in FIGS. 6 and 7 with the door closed, accompanying the door opening operation of the inside door handle (not shown). When the inside open lever 21 is actuated in the door opening direction, the timing at which the second push arm 21d of the inside open lever 21 engages with the passive part 25b of the active lever 25 is the first push of the inside open lever 21. The first pushing arm portion 21c of the inside open lever 21 is moved by a predetermined amount earlier than the timing at which the arm portion 21c engages with the engaging arm portion 22d of the outside open lever 22. When engaged with the engaging arm portion 22d, the open link 23 in the locked state shown in FIG. It has moved to the unlock state. Therefore, after that, the operation similar to the operation of (a) described above can be obtained, and the door can be opened. The so-called one-motion function (the door in a door-locked state by once opening the door) Can be opened).

“(E) Operation when the door is locked with the door open and the door is closed without operating the door handle”
In this embodiment, the lift lever 12 of the double lock type vehicle door lock device 100 is provided with the push leg 12c and the open link 23 is provided with the passive body 23b, so that the door is opened. In this state, for example, when a lock knob (not shown) is locked, the door is locked as shown in FIGS. 6 and 7, and the door is closed without operating the door handle. The latch 11 of the latch mechanism 10 is engaged with a striker (not shown), and the rotation shaft 13 of the pole is integrated with the lift lever 12 and temporarily rotates in a clockwise direction in FIG. . For this reason, when the door is closed, an operation in which the pushing leg portion 12c of the lift lever 12 shown in FIG. 7 pushes the passive body portion 23b of the open link 23 is obtained.

  Thereby, the push arm portion 25c of the open link 23 and the active lever 25 is moved from the locked state shown in FIG. 7 to the unlocked state shown in FIG. 11, and the door locked state is automatically canceled. Therefore, at this time, the unlocking operation is obtained by closing the open door in the door lock state, and the door lock state shown in FIGS. 6 and 7 is the door shown in FIGS. It becomes unlocked, and so-called key confinement operation can be prevented.

“(F) Operation when the door is locked with the door open and the door is closed with the outside door handle opened.”
The unlocking operation by the door closing operation of (e) described above is performed after the door is opened, the lock knob (not shown) is locked and the door is locked as shown in FIG. 6 and FIG. A side door handle (not shown) can be opened by opening the door, and the door can be closed in this state to cancel the operation. In this case, the state shown in FIG. 7 is changed to the state shown in FIG. 12 (when the door is closed, the rotation shaft 13 of the pole temporarily rotates together with the lift lever 12 for a predetermined amount and then returns to the original state). In this case, an operation in which the push leg 12c of the lift lever 12 is swung with respect to the open link 23) is obtained, the open link 23 is maintained in the locked state, and the active lever 25 is maintained in the locked position. For this reason, if the outside door handle (not shown) is then returned to the original position, the outside open lever 22, the open link 23, the spring 24, etc. in the state shown in FIG. 12 return to the state shown in FIG. The door lock state is maintained and keyless lock is possible.

“(G) Operation when setting the double lock operating member in the door locked state”
In this embodiment, when the door is closed and the double lock type vehicle door lock device 100 is in the door lock state as shown in FIGS. 6 and 7, the double lock operation member is set and operated. The double lock lever 27 in the unset position shown in FIG. 6 moves to the set position shown in FIGS. 13 and 14, and the lower end portion 27c of the double lock lever 27 is open link 23 as shown in FIG. The engagement arm portion 23f is close to and opposed to the engagement arm portion 23f.

  For this reason, in this state (double lock state), for example, when the lock knob is illegally unlocked from the outside of the vehicle (attack from the outside) in association with the active lever 25 in the locked position, the active lever 25 is moved from the locked position. Although switched to the unlocked position, the double lock lever 27 is maintained at the set position and engages with the open link 23 to prevent the open link 23 from moving from the locked state to the unlocked state. In addition, when the inside open lever 21 linked to the active lever 25 in the lock position is illegally operated (attacked from the outside) in the door opening direction from the outside of the vehicle, the same operation as described above is obtained.

  Therefore, the open link 23 is held in a locked state, and unauthorized unlocking can be prevented. At this time, since the active lever 25 is switched from the locked position to the unlocked position by an unauthorized operation from outside the vehicle (attack from the outside), a position switch (not shown) attached to the active lever 25 (usually a lock / unlock) It is also possible to detect the above-described attack by the action of (provided for detecting the lock) (attack detection by a position switch).

  In the double lock type vehicle door lock device 100 of the above-described embodiment, the spring 24 interposed between the outside open lever 22 and the open link 23 attaches the open link 23 to the unlocked state. The open link 23 is held so as to be movable relative to the lift lever 12 to allow the open link 23 to return to the initial position. Further, the push arm portion 25c of the active lever 25 can be detached from the open link 23 so as to allow the open link 23 that is locked to the open link 23 to move to the unlocked state.

  For this reason, when the door handle and the locking / unlocking operation member are simultaneously operated in the door lock state (the door locked state) to panic, the open link 23 is connected to the lift lever 12 as shown in FIG. On the other hand, it is held so as to be relatively movable, and the return to the initial position is allowed. Therefore, even in the panic state described above, by returning the outside open lever 22 to the initial position, the open link 23 returns to the initial position while being in the unlocked state, and enters the door unlocked state (the door unlocked state). Switching can be performed smoothly.

  By the way, in the double lock type vehicle door lock device 100 of the above-described embodiment, when the panic state is caused as described above, as shown in FIG. 10, between the outside open lever 22 and the open link 23. Since the interposed spring 24 functions as described above, it is not necessary to interpose the spring on the active lever 25 itself, and the active lever 25 can be formed of a single member. Therefore, the components from the active lever 25 to the open link 23 can be three components such as the active lever 25, the spring 24, and the open link 23, and can be configured simply and inexpensively.

  In the double lock type vehicle door lock device 100 of the above-described embodiment, as shown in FIG. 4, the lift lever 12 is provided with the pushing leg portion 12 c, and the open link 23 is provided with the passive trunk portion 23 b. Therefore, with the door opened, the active lever 25 is switched from the unlocked position to the locked position by the locking operation of the locking / unlocking operation member to set the door locked state, and the door is operated without operating the door handle in this state. When closed, the pushing leg 12c of the lift lever 12 pushes the passive body 23b of the open link 23.

  For this reason, using this operation, the open link 23 can be moved from the locked state to the unlocked state, and the active lever 25 can be moved from the locked position to the unlocked position. Therefore, in this case, the door lock state can be automatically canceled by closing the open door in the door lock state.

  By the way, in this case, the plane on which the main body of the lift lever 12 rotates and the plane on which the main body of the open link 23 tilts are arranged in parallel, the push leg 12c is provided on the lift lever 12, and the open link The above-described canceling function can be added without increasing the number of components. For this reason, it can be implemented simply and inexpensively.

  Further, in the double lock type vehicle door lock device 100 of the above-described embodiment, as shown in FIG. 2, the second open arm portion 21 d is provided on the inside open lever 21, and the active lever 25 is provided with a passive portion. 25b is provided, and when the door is closed and the active lever 25 is in the locked position, when the inside door handle is operated to open the door, the inside open lever 21 operates in the door opening direction, and the inside open. An operation in which the second pushing arm portion 21d of the lever 21 pushes the passive portion 25b of the active lever 25 is obtained.

  For this reason, using this operation, the active lever 25 can be moved from the locked position to the unlocked position, and the open link 23 can be moved from the locked state to the unlocked state. Therefore, in this case, in the closed door in the door lock state, the door lock state can be automatically released by the door opening operation of the inside door handle, and a so-called one-motion function is obtained.

  By the way, in this case, it can be implemented by providing the inside push lever 21 with the second pushing arm portion 21d and providing the active lever 25 with the passive portion 25b. It is possible to add a motion function. For this reason, it can be implemented simply and inexpensively.

  Further, the double lock type vehicle door lock device 100 according to the above-described embodiment includes a double lock lever 27 linked to the open link 23, and a component for switching the double lock lever 27 between the unset position and the set position (first part). By removing the second drive mechanism 50 and the like, it is possible to obtain a door lock device of a normal lock specification. In addition, a component other than the double lock lever 27 linked to the open link 23 and the component for switching the double lock lever 27 between the unset position and the set position (the second drive mechanism 50, etc.) includes a double lock mechanism. It is the same as a component with a simple configuration (a component not having an unnecessary function) used in a door lock device of a normal lock type that does not include (double lock lever 27, second drive mechanism 50, etc.). .

  Therefore, components other than the double lock mechanism (components excluding the double lock lever 27, the second drive mechanism 50, etc.) used in the double lock specification door lock device, and a normal that does not include the double lock mechanism. It is possible to manufacture both the door lock devices simply and inexpensively by sharing the components used in the door lock device of the lock specification with a simple configuration.

  Further, in the double lock type vehicle door lock device 100 of the above-described embodiment, the double lock lever 27 is assembled so as to be movable along the guide groove 91a provided in the main body 91 of the housing 90, and is set to the set position. 14 and 15, the lower end portion 27 c is configured to be close to and opposed to the engagement arm portion 23 f formed on the open link 23. For this reason, the double lock lever 27 can be implemented with a simple rod-like structure, and the occupied space in the housing 90 may be small, which contributes to the downsizing of the door lock device.

  In the above embodiment, when the inside door handle is operated to open the door in the closed door in the door lock state, the second pushing arm portion 21d of the inside open lever 21 is engaged with the passive portion 25b of the active lever 25. The timing at which the first open arm 21c of the inside open lever 21 is engaged with the engaging arm 22d of the outside open lever 22 is the timing at which the first open arm 21c of the inside open lever 21 is driven. Is set so as to be a predetermined amount earlier than the timing of engaging with (the driving start timing of the outside open lever 22 toward the operating position by the inside open lever 21). Lock by pull operation However, the drive start timing of the active lever 25 toward the unlocked position by the inside open lever 21 is the operating position of the outside open lever 22 by the inside open lever 21. It is also possible to configure and implement so-called double pull function (function to unlock by inside door handle double pull operation) by setting it to be delayed by a predetermined amount compared to the drive start timing toward It is.

  In the above-described embodiment, the canceling function and the one-motion function are configured to be obtained. However, it is also possible to configure and implement such a function that is not obtained. . Further, in the above embodiment, the present invention is applied to the double lock type vehicle door lock device 100 attached to a door (not shown) provided on the front right side of the vehicle. As well as the double lock type vehicle door lock device mounted on the door mounted on the vehicle, the same applies to the double lock type vehicle door lock device mounted on the door mounted on the rear right side or rear left side of the vehicle. Alternatively, it can be implemented with appropriate modifications.

  Further, in the above embodiment, a configuration (a panic countermeasure mechanism) such as interposing a spring 24 between the outside open lever 22 and the open link 23 is adopted, and the door unlocked state ( The door can be smoothly switched to the unlocked state. However, when the present invention is implemented, it is described in, for example, Japanese Patent Application Laid-Open No. 2006-233507 instead of the above-described panic countermeasure mechanism.
