Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing device for a vehicle door that can be opened and closed vertically, and particularly to
The present invention relates to an opening/closing device for a vehicle door of a vertical opening/closing type, in which the opening/closing device for a vehicle door of a vertical opening/closing type is configured such that unless either one of the opening/closing body (1) and the lower opening/closing body is opened, the other cannot be opened.

[Prior Art] Conventionally, such a vertical opening/closing vehicle door opening/closing device has been disclosed, for example, in Japanese Patent Application Laid-open No. 56-53920 and U.S. Pat.
．． Those described in Japanese Patent No. 157,844 and the like are known.

In the former method, the operating rod for opening and closing the lower opening/closing body is installed in a storage chamber recessed in the upper edge of the lower opening/closing body, and when the upper and lower opening/closing bodies are closed, this storage chamber is closed to the lid. The lot is blocked, making it impossible to operate the operation lot. and,
When opening the lower opening/closing body, after opening the upper opening/closing body, release the locking mechanism using the operating loft at the upper edge of the lower opening/closing body, so that the lower opening/closing body can be opened. ing.

In addition, in the latter case, the upper opening/closing body and the lower opening/closing body are unlocked by rotating the key cylinder to the left and right, respectively. The rotation operation is prevented by a block member provided within the link mechanism. Therefore, when performing an opening operation of the lower opening/closing body, the key cylinder is rotated to the left to unlock the upper opening/closing body, and at the same time as opening the door, the blocking by the blocking member is released. Then, the key cylinder can be rotated to the right to open the lower opening/closing body.

[Problems to be Solved by the Invention] However, in the former of the above-mentioned conventional devices, there is a problem in operability because the operating points are spread over multiple locations when performing the opening operation, and the storage chamber is closed. There is a problem in that the lid protrudes from the upper opening/closing body, which is aesthetically undesirable.

In addition, in the latter case, since the unlocking operation of the lower opening/closing body is forcibly blocked by the block member, there is a risk that the member may be deformed if a large force is applied to the block member due to erroneous operation. However, there are durability issues.

An object of the present invention is to solve the problems of such conventional devices, reliably prevent erroneous operations when opening the vertical opening/closing body, and provide an opening/closing device for a vertical opening/closing vehicle door that has excellent operability and durability. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes an upper opening/closing body attached to the upper edge of the vehicle opening via a hinge device so as to be able to open and close; A lower opening/closing body is attached to the lower edge via a hinge device so as to be able to open and close, and is provided with a second locking mechanism on the side. A second
A locking mechanism, a first link mechanism that releases the first locking mechanism, which is linked to the rotation operation of the handle provided on the lower opening/closing body, and is also linked to the opening/closing movement of the upper opening/closing body. 1. lJ
A link mechanism with a missing swing function that disables the release operation on the side of the first link machine only when the first link is activated, and a key cylinder that is provided on the lower opening/closing body and can be moved to the locked and unlocked states by rotational movement and can be moved in the axial direction. and a second link mechanism that releases the second lock mechanism in response to an axial movement operation of the key cylinder in an unlocked state.

[Function] According to the present invention, when the upper full opening/closing body and the lower opening/closing body are in the closed state, the lower opening/closing body locks the side edge of the vehicle entrance part by the first locking mechanism provided on the side thereof. The upper opening/closing body and the lower opening/closing body are locked by second locking mechanisms disposed at the lower edge and the upper edge, respectively.

Even if an attempt is made to release the first locking mechanism by operating the handle in order to open the lower opening/closing body in such a state, the first linkage mechanism that releases the first locking mechanism will fail due to the linkage mechanism with a missing function. One release operation is disabled, and it is impossible to open the lower opening/closing body.

On the other hand, to open the upper opening/closing body, turn the key cylinder to the lock-off position. When the key cylinder is moved in the axial direction at this position, the second link mechanism responds to this, the second lock mechanism is released, and the upper opening/closing body is opened.

When the upper opening/closing body opens, the missing function of the link mechanism with a missing function that is linked to the opening/closing movement is released, and the first link mechanism and the link mechanism with a missing function become linked. Therefore, if the handle is rotated in such a state, the operating force of the link mechanism with a missed function is transmitted to the first link mechanism, the first lock mechanism is released, and the lower opening/closing body is opened. be.

and 22 are provided in a protruding manner to rotatably support a first operating lever 23 and a second operating lever 24, respectively, within a plane orthogonal to the plane of rotation of the bell crank 10.

One end of the first operating lever 23 is connected to the operating rod 25 via a rod holder 25A, and the other end is rotatably connected to the swing arm 26 via a pin 23A.

One end of the second operating lever 24 has an engaging portion 24A protruding from a long hole D2 formed in a recessed step D1 formed at the upper edge of the lower opening/closing body, and the other end has an engaging portion 24A that is bent at right angles. A bent portion 24B is formed, and an engagement hole 24G is bored in this bent portion 24B. This second operating lever 24 is connected to the pin 2.
By the spring 22A wound around the upper opening/closing body C,
A rotational force is applied in the opening direction of the opening 4', and the opening is biased toward the opening direction, and when the opening is opened, the opening is in the position shown by the solid line in FIG.

The swinging arm 26 has a strip portion 26A formed from its midsection to its tip, which is fitted into the engagement hole 24G of the second actuating lever 24 described above. A protruding piece 26B is formed that extends to the bell crank IO of the first link mechanism G and has an engaging surface that can be engaged with the engaging arm 10E of the bell crank IO of the first link mechanism G.

Therefore, the first operating lever 23. second actuation lever 24;
The actuating rod 25 and the swing arm 26 constitute a link mechanism H with an idle swing function.

Furthermore, an escutcheon 30 is provided at the upper center of the outside of the lower opening/closing body, and a handle 34 is connected to the handle 34 via a shaft 32.
is rotatably supported. A lever 34A is integrally formed on the back side of the handle 34, and the tip of the lever 34 is connected to one end of the aforementioned operating rod 25 by a rod holder 25B.

The escutcheon 30 is further provided with a key cylinder 36 movable in the axial direction.
6 is provided with a rotating lever 38 at its end that can be rotated integrally by the rotational locking/unlocking operation of a key and can be moved to the locked and unlocked positions. 38A is a suppressing protrusion that is screwed onto the end of the rotating lever 38 so that its stroke can be adjusted.

Furthermore, 40 is a bell crank supported rotatably around a pin 40 provided on a support part 308 integrally formed with the escutcheon 30, and has an engaging part 40B at one end and a bell crank at the other end. The end is connected to the actuating rod 42 via a rod holder 42A.

Thus, the bell crank 40 and the operating rod 42 constitute a second link mechanism J.

Next, a second locking mechanism for locking the upper opening/closing body C and the lower opening/closing body in a closed state will be explained.

In this embodiment, the upper opening/closing body C has a glass hatch 50.
It is composed of two holes 50A at its lower edge.

50B is drilled. Then, a mounting bracket 56 having a fixed handle 52 fixed on the front surface and a U-shaped striker 54 fixed on the back surface is mounted with screws or the like using these holes 508 and 50B. In addition, the mounting bracket 56
A projecting piece 568 is formed on one side of the lever 56 to abut against the engaging portion 24A of the second actuating lever 24 described above.

On the other hand, a locking device 60 is provided in the recessed step DI at the upper edge of the lower opening/closing body. As is well known, this locking device 60 includes a bouncing 62, pins 62A and 62B supported by the bouncing 62, a latch 64 and a lock plate 66 rotatably supported around the pins 62A and 62B, and a latch 64. It includes a spring (not shown) that biases in the release direction (see FIG. 4). A pin 66A is implanted in the lock plate 66 and engages with an engagement groove 68A at the end of the release lever 68. The release lever 68 is rotatably supported around a pin 72A provided on a bracket 72 fixed to a panel 70 constituting the lower opening/closing body, and one end is connected to the aforementioned actuation rod 42 (the third (see figure).

Next, the first locking mechanism E provided on both sides of the lower opening/closing body will be explained with reference to FIG. 5.

Since the left and right sides are the same, only the left side is typically shown in the figure, and a subscript A is added to the reference numeral to distinguish it from the right side (subscript B). Further, since this first locking mechanism E is basically the same as the second locking mechanism F described above except for the attachment part, only the external appearance will be described. That is, the housing 82A and the bracket 84A of the locking device BOA are fixed to the panel 70 constituting the lower opening/closing body, and the bracket 84A
The release lever 16 is connected to the operating rod 14A of the first link mechanism G so as to be rotatable around a pin 86 provided in the release lever 16.
A is supported. A striker 888 is fixed to the side edge of the vehicle opening B.

Roughly speaking, an example suitable as a drive unit for the second operating lever 24 when the upper opening/closing body C is constituted by a thin glass hatch 50 will be described based on FIG. 6.

In such a case, the protrusion 58A of the mounting bracket 56 and the second
Since the distance between the actuating lever 24 and the engaging portion 24A is large, it is preferable to provide a sliding push rod 90 as an intermediate member. For example, a long hole 62B is provided in the bent portion 62Δ of the lower edge of the housing δ2, and the guide pins 92A, 92! are fixed to the sliding push rod 90 through the long hole 62B. All you have to do is let it guide you. Of course, instead of using the sliding push rod 90, it is also possible to adjust the amount of protrusion from the protruding piece 56, but in that case, when the upper opening/closing body C is opened, it becomes a protrusion, which is dangerous.

The operation of the embodiment of the present invention having the above structure will be explained below.

[Closed state of upper and lower opening/closing bodies C and D] In this state, the lower opening/closing body is locked by the first locking mechanism E, and the upper opening/closing body C and the lower opening/closing body are locked by the second locking mechanism F. As stated above, this is the case.

Therefore, in order to open the glass hatch 50, the fixed handle 5
Even if you pull 2, it cannot be opened because it is locked by the second locking mechanism F.

Further, even if an attempt is made to release the first locking mechanism E by operating the handle 34 to open the tailgate D, the rotating operation of the handle 34 will cause the first locking mechanism E to be released.
It is not transmitted to link mechanism G.

That is, as shown in FIGS. 1 and 6, the counterclockwise rotation of the handle 34 causes the first operating lever 23 to rotate clockwise via the operating rod 25, and the swing lever 26
push upward. However, at this time, the glass hatch 50 is in a closed state, and the second operating lever 24 is rotated counterclockwise by the sliding push rod 90 against the spring 228. Therefore, the bent portion 2 of the second operating lever 24
Swing lever 2 fitted into engagement hole 24C provided in 4B
The pin 23 also rotates eight times clockwise, and the engaging arm 10E of the bell crank 10 forming the first link mechanism G
and the projecting piece portion 26B are in a positional relationship in which they cannot engage with each other.

Therefore, even if the swinging lever 26 is pushed upward and moves, it will only be guided to the engagement hole 24C without any effect on the first link mechanism G, that is, it will act as an idle mechanism. Tailgate D cannot be opened.

[Opening of the upper opening/closing body, closed state of the lower opening/closing body] To open the glass hatch 50, insert the key into the key cylinder 36 and move the rotary lever 38 to the unlocked state shown by the solid line in FIG.
Rotate. Then, the key cylinder 36 is pushed in against a spring (not shown). Then, the bell crank 40 is rotated by the pressing protrusion 38A, pulling down the actuation rod 42, and releasing the release lever 6.
8 in the third figure clockwise direction. This release lever 68
The rotation causes the lock plate 66 to rotate counterclockwise in the fourth figure to release the lock. Thus, the glass hatch 50 can be opened.

When the glass hatch 50 is opened, the second operating lever 24 is rotated back clockwise in the sixth figure by the spring 22A, and the swinging lever 26 is rotated counterclockwise, so that the protruding piece 25B and the engaging arm 10E are engaged. match.

Therefore, when the handle 34 is rotated in this state, the swing lever 26 is pushed up as described above, but this time, the engagement arm 1
The bell crank IO is rotated counterclockwise in the third drawing via 0E, and the release levers 16A and 16B are rotated via the operating rods 14A and 14B to release the first locking mechanism E.

Thus, the tailgate D can be opened.

[Closing the vertical opening/closing body] First, when the tailgate D is closed, the first locking mechanism E is activated and the closed state is maintained. Next, when the glass hatch 50 is closed, the second locking mechanism F is activated and the closed state is maintained.

In this state, the key cylinder 36 may be operated with a key to bring the rotary lever 38 into the locked state indicated by the two-dot chain line in FIG.

[Effects of the Invention] As is clear from the above description, according to the present invention, erroneous operations such as opening only the lower opening/closing body can be reliably prevented, and the upper and lower doors can be opened from one place.
Since the present invention is equipped with a missed swing mechanism, it is possible to obtain a vertical opening/closing vehicle door opening/closing device with excellent operability and durability.
