Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing device for a vehicle door that opens and closes vertically, and in particular, an upper and lower opening/closing body that cannot be opened unless either one of the upper and lower opening/closing bodies is opened. The present invention relates to an opening/closing device for an opening/closing vehicle door.

[Prior Art] Conventionally, as such an opening/closing device for a vertically opening/closing vehicle door, those described in, for example, Japanese Patent Laid-Open No. 56-53920 and US Pat. No. 4,157,844 are known.

In the former case, the operating rod that controls the opening and closing of 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. The valve is blocked, making it impossible to operate the operating rod. When opening the lower opening/closing body, after opening the upper opening/closing body, the lock mechanism is also released using the operating rod on the upper edge of the lower opening/closing body, so that the lower opening/closing body can be opened. I have to.

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. Rotation to the right is prevented by a blocking member cut into the link mechanism. Therefore, when opening 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 the door is opened, 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 operation points are spread over multiple places when performing the opening operation, and there is also a problem in the operability of the device in order to close the storage chamber. There is a problem in that the lid protrudes from the upper opening/closing body and is not aesthetically pleasing.

In addition, in the latter case, since the unlocking operation of the lower opening/closing body is forcibly blocked by the blocking member, if a large force is applied to the blocking member due to an erroneous operation, there is a risk that the member may be deformed. 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 that it can be opened and closed and is equipped with a first locking mechanism on the side, a lower edge of the upper opening/closing body, and an upper edge of the lower opening/closing body. a second lock mechanism that is arranged and capable of locking both in the closed state, a first link mechanism that releases the first lock mechanism, and an upper opening and closing body that is linked to the rotating operation of a handle provided on the lower opening and closing body A link mechanism with an idle swing function that is linked to the opening and closing movement of the first link mechanism and disables the release operation of the first link mechanism only when the first link mechanism is closed; a key cylinder that can be moved in the direction;
The present invention is characterized by comprising 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 opening/closing body and the lower opening/closing body are in the closed state, the lower opening/closing body is locked to the side of the vehicle opening 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 lock mechanism by operating the handle in order to open the lower opening/closing body in such a state, the first link mechanism that releases the first lock mechanism will not be activated by the link mechanism with the missing function. Therefore, the release operation is impossible, 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 linked to the opening/closing movement is released, and the first
The link mechanism and the link mechanism with a missed swing function become linked. Therefore, if the handle is rotated in such a state, the operating force of the link mechanism with a missing swing function is transmitted to the first link mechanism, the first lock mechanism is released, and the lower opening/closing body is opened. It is.

[Examples] Examples of the present invention will be described below with reference to the accompanying drawings.

An embodiment of the present invention is shown in FIGS. 1 to 6.

In FIG. 2, A is a vehicle equipped with an opening B at the rear to which the present invention is applied;
An upper opening/closing body C such as a glass hatch is attached to the upper edge of the opening B via a hinge device, and a lower opening/closing body D called a tailgate is attached to the lower edge of the opening B via a hinge device.

Further, a lock mechanism (hereinafter referred to as a second lock mechanism) F is provided at the lower edge of the upper opening/closing body C and at the upper edge of the lower opening/closing body D, which can lock both in the closed state.

Furthermore, a link mechanism for releasing the aforementioned lock mechanism will be explained.

Reference numeral 10 denotes a bell pivotably supported in a plane parallel to the surface of the lower opening/closing body D around a pin 12A implanted in a bracket 12 fixed to an inner panel in the lower opening/closing body D. It is a crank, and operating rods 14A, 14B are connected to both ends 10A, 10B via rod holders 10C, 10D, and has an engagement arm 10E in its midsection.

The ends of the operating rods 14A and 14B are connected to release levers 16A and 16B of the first locking mechanism E provided on the left and right sides of the lower opening/closing body D, respectively (see FIG. 5; however, this figure (only the left side is shown).

Thus, the bell crank 10 and the operating rods 14A, 14B constitute a first link mechanism G.

Next, the aforementioned bracket 12 has pins 21 and 22 protruding from it as shown in the figure, and the bell crank 1
The first actuating lever 23 and the second actuating lever 24 are each rotatably supported within a plane perpendicular to the rotational plane of 0. One end of the first actuation lever 23 is connected to the actuation rod 25 via a rod holder 25A.
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 D, 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 24C is bored in this bent portion 24B. The second operating lever 24 is always biased by a spring 22A wound around the pin 22 so as to apply a rotational force in the direction in which the upper opening/closing body C is opened, and when it is opened, it is shown by a solid line in FIG. in position.

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

Thus, the first operating lever 23, the second operating lever 24, the operating rod 25, and the swinging 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 D, and a handle 34 is rotatably supported via a shaft 32. A lever 34A is integrally formed on the back side of the handle 34, and the tip of the lever 34A is connected to one end of the aforementioned actuating rod 25 by a rod holder 25B.

The escutcheon 30 is further provided with a key cylinder 36 movable in the axial direction, and this key cylinder 36 is integrally rotated by the rotational locking/unlocking operation of the key at its end, and locks and unlocks. It is equipped with a pivot lever 38 that can be moved to a locked position.
38A is a pressing 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 rotatably supported around 40A provided on a support portion 30A integrally formed with the escutcheon 30, and has an engaging surface 40B at one end, and a rod holder 42A at the other end. It is connected to the actuating rod 42 via.

Thus, the bell crank 40 and the actuating 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 D in the closed state will be explained.

In this embodiment, the upper opening/closing body C is composed of a glass hatch 50, and two holes 50 are provided at the lower edge of the hatch.
A and 50B are drilled. A fixed handle 52 is on the front surface, and a U-shaped striker 54 is on the back surface.
Mounting brackets 56 with fixedly attached holes 5
It can be attached using screws etc. using 0A and 50B. Note that a protruding piece 56A is formed on one side of the mounting bracket 56 and abuts against the engaging portion 24A of the second operating lever 24 described above.

On the other hand, a locking device 60 is provided in the recessed step D1 at the upper edge of the lower opening/closing body D. This lock device 6
0 is a housing 62 and a housing 6, as is well known.
2, a latch 64 and a lock plate 66 rotatably supported around the pins 62A, 62B;
4 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 D, and one end is connected to the aforementioned actuation rod 42 (the third (see figure).

Next, the first
The lock mechanism E will be explained with reference to FIG.

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 lock mechanism E is basically the same as the second lock 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 80A are fixed to the panel 70 constituting the lower opening/closing body D, and are rotatable around the pin 86A provided on the bracket 84A.
A release lever 16A connected to the operating rod 14A of the link mechanism G is supported. A striker 88A is fixed to the side edge of the vehicle opening B.

Furthermore, an example suitable for the drive section of the second operating lever 24 when the upper opening/closing body C is constituted by a thin glass hatch 50 will be described with reference to FIG. 6.

In such a case, the protrusion 56 of the mounting bracket 56
Since the distance between A and the engaging portion 24A of the second operating lever 2 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 a bent portion 62A obtained by bending the lower edge of the housing 62, and guide pins 92A and 92B fixed to a sliding push rod 90 are guided by this long hole 62B. do it. Of course, instead of using the sliding push rod 90, it is possible to adjust the amount of protrusion of the protruding piece 56A, but in that case, when the upper opening/closing body C is opened, a protrusion will result, 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 D is locked by the first locking mechanism E, and the upper opening/closing body C and the lower opening/closing body D are locked by the second locking mechanism F. As mentioned above, it is locked by

Therefore, even if the fixed handle 52 is pulled to open the glass hatch 50, the door cannot be opened because it is locked by the second locking mechanism F.

In addition, in order to open the tailgate D, the handle 3
4 to release the first lock mechanism E, the rotational movement of the handle 34 is not transmitted to the first link mechanism G that releases the first lock mechanism E. That is, as shown in FIGS. 1 and 6,
By rotating the handle 34 counterclockwise, the first
The actuating lever 23 rotates clockwise via the actuating rod 25, pushing the swinging lever 26 upward. However, at this time, the glass hatch 50 is in the closed state, and the second operating lever 24 is rotated counterclockwise by the sliding push rod 90 against the spring 22A. Therefore, the swing lever 26 fitted into the engagement hole 24C provided in the bent end portion 24B of the second operating lever 24 also rotates clockwise around the pin 23A, and the first link The engaging arm 10E and the projecting piece 26B of the bell crank 10 constituting the mechanism G 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 rotate the rotating lever 38 to the unlocked state shown by the solid line in FIG. and,
Push the key cylinder 36 against a spring (not shown). Then, the bell crank 4 is pressed by the pressing protrusion 38A.
0 rotates and pulls down the actuating rod 42, releasing the lever 6.
8 in the third figure clockwise direction. This rotation of the release lever 68 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.
The projecting piece 26B and the engaging arm 10E engage with each other.

Therefore, when the handle 34 is rotated in this state, the swing lever 26 is pushed up as described above, but this time, the key cylinder 1 is pushed up via the engagement arm 10E.
0 is rotated counterclockwise in the third figure, and the release levers 16A, 1 are rotated via the actuating rods 14A, 14B.
6B to release the first lock 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 to maintain the closed state. Next, when the glass hatch 50 is closed, the second lock mechanism F is operated and the closed state is maintained.

In this state, the key cylinder 36 may be operated with a key to place the rotary lever 38 in the locked state shown 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 an oscillation mechanism, it is possible to obtain a vertical opening/closing vehicle door opening/closing device with excellent operability and durability.
