Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle door mechanism, and more particularly to a vehicle door mechanism that can be opened and closed from either the left or right side.
[0002]
[Prior art]
Conventionally, a general vehicle door mechanism that opens and closes a side door of a vehicle includes a door hinge mechanism that supports a front end portion of a door body so as to be rotatable about a vertical axis on a vehicle body, and a rear end of the door body in a closed position. There is a door lock mechanism that locks the part to the vehicle body so that it can be unlocked. Recently, this type of door mechanism is applied to the back door of vehicles such as vans and wagons, so that the back door opens and closes around the vertical axis. The door mechanism has been put to practical use.
[0003]
A general door lock mechanism includes a door striker fixed to a frame (for example, a pillar) in the vicinity of a door opening of a vehicle body, a detachable position that can be engaged with and disengaged from the door striker, and an unreleasable and unremovable position. A latch pivotally supported by the door body so as to be pivotable over a position, a biasing member that biases the latch to a disengageable position, and the latch against the biasing force of the biasing member A locking member or the like that can be locked at a position where it cannot be detached is provided.
[0004]
In this door lock mechanism, when the opened door is closed, the latch held in the engagement / disengagement position rotates to the engagement / disengagement position side while engaging the door striker, and the latch is in the engagement / disengagement position. The door is locked by the locking member against the biasing force of the biasing member, and the door is automatically locked at the closed position. Further, if the door outer handle or the door inner handle is operated when the door is in the closed position, the latch to the latch by the latch member, that is, the door lock is released, and the latch and the door striker are disengaged to separate and separate the door. Can be opened.
[0005]
By the way, in the conventional vehicle door mechanism, the door can be opened and closed only from one side of the rear, but the back door of a vehicle such as a van or a wagon can be conveniently put in and out of the luggage, There is a request to open and close from either side of the vertical axis. In fields other than the recent automobile industry, door mechanisms capable of opening and closing doors from either the left or right side are being put into practical use, and it is conceivable to apply this technology to vehicle door mechanisms.
[0006]
For example, Fruit In the door mechanism of Kaihei 7-40959, a pair of left and right handles are attached to the door, and each handle has a vertically-oriented support shaft whose upper and lower ends are rotatably supported by a support portion outside the door. When the handle is operated, the support shaft corresponding to the handle is actuated, the upper and lower ends thereof are detached from the support part, and the door can be opened and closed from the operated handle side with the other support shaft as the axis. It is like that.
[0007]
[Problems to be solved by the invention]
When a conventional vehicle door mechanism is applied and a back door of a vehicle such as a van or a wagon is opened and closed around a vertical axis, the back door can be opened and closed only from one side, for example, an automobile. If there are obstacles such as other cars or walls near the open side of the back door of the car, it is easy to put in and out of the luggage, etc. unless the car is moved to avoid the obstacles There is a problem that you can not.
[0008]
on the other hand, Fruit In the door mechanism disclosed in Kaihei 7-40959, the door can be easily removed by operating both handles and removing both support shafts from the support portion outside the door. When the mechanism is applied to a vehicle door mechanism, it is possible for an occupant or the like to easily remove the entire heavy back door from the vehicle body, which is problematic in terms of safety.
[0009]
An object of the present invention is to provide a vehicle door mechanism that can reliably prevent the entire vehicle door from being detached from the vehicle body and can open and close the vehicle door from either the left or right side.
[0010]
[Means for Solving the Problems]
The vehicle door mechanism according to claim 1 is a vehicle door mechanism that opens and closes the vehicle door from either the left or right side, and is provided in the vicinity of both left and right ends of the vehicle door. And a door striker provided on the vehicle body side, and an engaging member provided on the door side and detachably operated and engaged with the door striker. Door hinge mechanism and left of vehicle door Each on the right Hinge separating means for separating the door hinge mechanism into the vehicle body side and the door side, and separation preventing means for making the other door hinge mechanism unseparable when the left and right door hinge mechanisms of the vehicle door are separable And with The separation preventing means includes an actuating member that interlocks with the operation of the door outer handle and interrupts the operation transmission path to the engaging member by the hinge separating means. It is characterized by this.
[0011]
Here, for example, when the left and right door handles are provided on the vehicle door and the left door handle is operated, the left door hinge mechanism can be separated into the vehicle body side and the door side by the hinge separating means, and the separation preventing means By making the right door hinge mechanism inseparable by operating the right door handle, the right door hinge mechanism can be separated into the vehicle body side and the door side by the hinge separating means, and the left door hinge mechanism by the separation preventing means. Can be configured to be inseparable.
[0012]
In this vehicle door mechanism, when the left and right door hinge mechanisms of the vehicle door can be separated into the vehicle body side and the door side by the hinge separating means, the other left and right door hinge mechanisms of the vehicle door are separated by the separation preventing means. Since the vehicle door is supported by the other left and right door hinge mechanisms so as to be rotatable about the vertical axis, the left and right door hinge mechanisms are separated, and the left and right door hinge mechanisms are separated. Can be opened and closed from the side.
[0013]
In other words, it is possible to reliably prevent the entire vehicle door from being detached from the vehicle body, and to open and close the vehicle door from any side of the left and right sides. If there are obstacles such as automobiles or walls, you can open and close the vehicle door from the other side of the obstacles without moving the vehicle to avoid the obstacles. Etc. can be easily performed.
[0014]
This Here, for example, the engaging member is configured to be operable over a disengageable position where it can be engaged / disengaged with the door striker and a disengageable position where it cannot be disengaged.
[0015]
Moreover, In this vehicle door mechanism, the engagement member and the door striker (one of the left and right door hinge mechanisms) can be separated by enabling the engagement member of the left and right door hinge mechanisms to be operable by the hinge separating means. Further, by disengaging the engaging member of the other door hinge mechanism on the left and right sides at a predetermined disengageable position by the separation preventing means, the engaging member and the door striker (the other left and right door hinge mechanism) It can be made inseparable.
[0016]
in front The separation preventing means includes an operation member that interlocks with the operation of the door outer handle and interrupts the operation transmission path to the engagement member by the hinge separation means. But example For example, the operation transmission path is for switching the engagement member from an inoperable state to an operable state.
[0017]
And In this vehicle door mechanism, when the door outer handle is operated to open and close the vehicle door from the left and right sides, the operating member operates in conjunction with the door handle, and the left and right hinges of the vehicle door by the hinge separating means Even if the door outer handle is operated to open and close the vehicle door from the left and right sides, the operation transmission path to the mechanism engagement member is cut off, the engagement member of the left and right hinge mechanism of the vehicle door is operated. It becomes impossible to make it possible, and the left and right door hinge mechanisms can be reliably made unseparable.
[0018]
Claim 2 The vehicle door mechanism of claim 1 In the invention, the separation preventing means includes an operating member that interlocks with the operation of the door inner handle and blocks an operation transmission path to the engaging member by the hinge separating means.
[0019]
In this vehicle door mechanism, basically the claim is made. 1 Although the same effect as this effect is achieved, the door for the vehicle can be opened and closed from either the left or right side by operating the door inner handle from the vehicle interior (cargo compartment) side. Further, the operation member is operated so that the operation transmission path to the engagement members of both the left and right door hinge mechanisms is blocked, so that the vehicle door cannot be opened and closed by operating the door outer handle from the outside of the vehicle. be able to.
[0020]
Claim 3 The vehicle door mechanism of claim 1 or 2 In the present invention, the operation member is configured to be operated by an operation member other than a door handle.
The operating member can be operated without being interlocked with the door handle by an operation member other than the door handle. By holding the operating member at a certain position, the vehicle door can always be opened and closed only from the left and right sides with the door handle. It becomes possible to do so.
[0021]
[0022]
[0023]
[0024]
Claim 4 The vehicle door mechanism according to claim 1. 3 In any one of the inventions, the vehicle door is a back door.
Therefore, the back door can be opened and closed from either the left or right side. If there is an obstacle such as another car or wall near the side of the back door, the vehicle is moved to avoid the obstacle. Even without this, by opening the back door from the opposite side of the obstacle, it is possible to easily take in and out the luggage to and from the luggage compartment.

[0049]
The operation and effect of the door mechanism 5 will be described. As shown in FIGS. 2 and 3, when the back door 4 is in the closed state, the latch 32 of the door hinge mechanism 30A (30B) engages with the door striker 31, and the latch 32 rotates clockwise (disengagement). The locking member 41 is locked at a non-engageable position so as not to rotate to the possible position side, and is inoperable.
[0050]
As shown in FIG. 8, when the door outer handle 7A (7B) is not operated, the engaging portion 53b at the end of the pair of push-pull wires 53 is one of the operating members 51 as shown in FIG. The end portions of the four push-pull wires 43 and 44 are held at positions that do not interfere with the movement of the actuating member 51 in the left-right direction while being engaged with the outer end portions of the pair of long holes 53b. Yes.
[0051]
As shown in FIG. 10, for example, when the left door outer handle 7A is rotated by a predetermined amount around the support shaft 7c, only the push-pull wire 53 of the separation preventing mechanism 50 among the push-pull wires 43 and 53 is pushed. As shown in FIG. 11, the engaging portion 53 b at the end of the push-pull wire 53 is engaged with the inner end of the long hole 51 c of the operating member 51.
[0052]
Thereafter, as shown in FIG. 12, when the door outer handle 7A is further rotated by a predetermined amount around the support shaft 7c, only the push-pull wire 53 of the separation preventing mechanism 50 is further pushed, and the push-pull of the operation transmission path 42A. The engaging portion 43a of the wire 43 engages with the upper end portion of the long hole 7a of the door outer handle 7A.
[0053]
As shown in FIG. 13, when the push-pull wire 53 is further pressed, the operating member 51 is pushed rightward by the engaging portion 53b, and the operating member 51 is interposed between the push-pull wires 43, 44 of the operation transmission path 42A. The right end portion of is inserted. At this time, the engaging portion 53b of the push-pull wire 53 extending from the right outer door handle 7B is engaged with the middle portion of the long hole 51c.
[0054]
Thereafter, when the door outer handle 7A is further rotated around the support shaft 7c, both of the push-pull wires 43 and 53 are pushed, and the push-pull 44 facing the push-pull wire 43 as shown by a chain line in FIG. Is pushed through the actuating member 51. At this time, the actuating member 51 moves to the right while rotating counterclockwise around the pivot shaft 51b.
[0055]
When the push-pull wire 44 of the operation transmission path 42A is pushed, the push-pull is moved via the operation member 52 and the operation transmission member 45. Wire 46 (47) is pushed, and the locking member 41 rotates counterclockwise around the pivot shaft 34b from the state shown in FIG. 2, so that the locking of the locking member 41 to the latch 32 is released, and the latch 32 Becomes operable, and the left door hinge mechanism 30A becomes separable.
[0056]
In other words, when the door outer handle 7A is pulled in this state, the latch 32 is released from the door striker 31 while rotating to the disengageable position, and the door striker 31 and the latch 32 are separated from each other, as shown in FIG. As shown, the back door 4 can be opened from the left side. When the door outer handle 7 </ b> A is returned with the back door 4 opened, the engaging portion 41 a of the locking member 41 comes into slidable contact with the outer peripheral surface of the latch 32.
[0057]
When the left door hinge mechanism 30A is separable, as shown in FIG. 13, the operating member 51 moves to the right, and the operating member 51 is located between the push-pull wires 43 and 44 in the operation transmission path 42B. Since it is not interposed, the operation transmission path 42B to the latch 32 corresponding to the right hinge mechanism 30B is blocked, and the right door hinge mechanism 30B cannot be separated even if the right door outer handle 7B is operated.
[0058]
In the state where the back door 4 is opened from the left side, as shown in FIG. 4, the latch 32 is held in the engagement / disengagement position. Thereafter, when the opened back door 4 is closed, the latch in the engagement / disengagement position is performed. 32 engages with the door striker 31 and rotates to the unremovable position. The latch 32 is locked by the locking member 41 at the unremovable position, and the back door 4 is automatically locked at the closed position. The The inner surface of one end of the latch 32 is formed with a tapered surface 32b so that the latch 32 can be easily engaged with the door striker 32.
[0059]
According to the door mechanism 5, the door hinge mechanisms 30 </ b> A and 30 </ b> B respectively provided near the left and right ends of the back door 4 and the left side of the back door 4. Each on the right The hinge separation mechanism 40A (40B) that allows the door hinge mechanism 30A (30B) to be separated into the vehicle body 2 side and the door 4 side and the door hinge mechanism 30A (30B) on one of the left and right sides of the back door 4 are in a state that can be separated. Since the separation preventing mechanism 50 for making the other door hinge mechanism 30B (30A) impossible to be separated is sometimes provided, the back door 4 is reliably prevented from being detached from the vehicle body 2 so that the back door 4 can be moved from the left or right side. But it can be opened and closed.
[0060]
As a result, if there is an obstacle such as another car or wall near the side of the side of the back door 4, the vehicle 1 can be moved from the opposite side of the obstacle without moving the car 1 to avoid the obstacle. By opening the door 4, it is possible to easily take in and out the luggage to and from the luggage compartment 3.
[0061]
The door hinge mechanism 30A (30B) includes a door striker 31 provided on the vehicle body 2 side and a latch 32 provided on the door 4 side and detachably operated and engaged with the door striker 31. (40B), by enabling the latch 32 of one of the left and right door hinge mechanisms 30A (30B), the latch 32 and the door striker 31 can be separated, and the separation preventing mechanism 40A ( 40B), the latch 32 and the door striker 31 can be made unseparable by disabling the latch 32 of the left and right door hinge mechanism 30B (30A) at the disengageable position.

【The invention's effect】
According to the vehicle door mechanism of the first aspect, the door hinge mechanism provided in the vicinity of both left and right ends of the vehicle door and the left and right door hinge mechanisms of the vehicle door can be separated into the vehicle body side and the door side. And the separation preventing means for preventing the other door hinge mechanism from being separated when the left and right door hinge mechanisms of the vehicle door are separable, so that the entire vehicle door is detached from the vehicle body. It is possible to reliably prevent this from happening, and the vehicle door can be opened and closed from either the left or right side. As a result, there are obstacles such as other automobiles or walls in the vicinity of one side of the vehicle door. In this case, opening and closing the vehicle door from the opposite side of the obstacle enables easy loading and unloading of the luggage into the luggage compartment without moving the vehicle to avoid the obstacle. .
[0070]
And The door hinge mechanism has a door striker provided on the vehicle body side and an engagement member provided on the door side and detachably operated and engaged with the door striker. By enabling the engagement member, the engagement member and the door striker (one of the left and right door hinge mechanisms) can be separated, and the separation preventing means can be used to engage the other door hinge mechanism. By disabling the combined member at a predetermined disengagement position, the engagement member and the door striker (the other left and right door hinge mechanism) can be made unseparable.
[0071]
And The separation preventing means includes an actuating member that interlocks with the operation of the door outer handle and interrupts the operation transmission path to the engaging member by the hinge separating means, so that the door outer handle is opened and closed to open and close the vehicle door from the left and right sides. When the is operated, the operation member is interlocked, and the door outer handle is used to block the operation transmission path to the engagement member of the other left and right hinge mechanism of the vehicle door by the hinge separating means, and to open and close the vehicle door from the left and right other side. Even if is operated, the engagement member of the other left and right hinge mechanism of the vehicle door cannot be made operable, and the other left and right door hinge mechanism can be reliably made unseparable.
[0072]
Claim 2 According to the vehicle door mechanism 1 However, the separation preventing means has an operation member that interlocks with the operation of the door inner handle and blocks the operation transmission path to the engagement member by the hinge separation means. The door for the vehicle can be opened and closed from either the left or right side by operating the door inner handle, and the operating transmission path to the engaging members of both the left and right door hinge mechanisms is blocked by operating this operating member. With this configuration, the vehicle door cannot be opened and closed by operating the door outer handle from the outside of the vehicle.
[0073]
Claim 3 According to the vehicle door mechanism, since the operation member is configured to be operated by an operation member other than the door handle, the operation member can be operated without being interlocked with the door handle by an operation member other than the door handle. By holding the actuating member at a certain position, it becomes possible to always open and close the vehicle door only from the left and right sides with the door handle.
[0074]
[0075]
[0076]
Claim 4 According to the vehicle door mechanism, 3 However, since the vehicular door is a back door, the back door can be opened and closed from either the left or right side, and another automobile is located near one side of the back door. If there is an obstacle such as a wall or a wall, opening and closing the back door from the other side of the obstacle allows you to put in and out the luggage without having to move the vehicle to avoid the obstacle. It becomes possible to carry out easily.
