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 this storage chamber is opened when the upper and lower opening/closing bodies are 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, release the lock mechanism using the operating rod on the upper edge of the lower opening/closing body, and then the lower opening/closing body can be opened. That's what I do.

Furthermore, in the latter case, the lock mechanism of the upper opening/closing body and the lower opening/closing body are released by rotating the key cylinder to the left or right, respectively, and the lock mechanism of the lower opening/closing body is released by the unlocking operation of the lower opening/closing body. A certain rotational operation to the right is prevented by a blocking member provided within 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 release operation of the lower opening/closing body is forcibly blocked by the blocking member,
If a large amount of force is applied to the block member due to erroneous operation or the like, the member may be deformed, which poses a problem in terms of durability.

It is an object of the present invention to provide a vertical opening/closing vehicle door opening/closing device which eliminates the problems of such conventional devices, reliably prevents erroneous operations when opening the vertical opening/closing body, and has excellent operability and durability. It is in.

[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 end of the vehicle opening via a hinge device so as to be movable in opening and closing, and a lower opening/closing body attached to the upper end of the vehicle opening. A lower opening/closing body is attached to the edge via a hinge device so as to be able to open and close, and is provided with a first locking mechanism on the side; A second lock mechanism is provided that can lock both in the closed state, a first link mechanism that releases the first lock mechanism, a handle provided on the lower opening/closing body, and a handle that is linked to the opening/closing movement of the upper opening/closing body. a second link mechanism that rotates the handle to the operating position when opened;
It is equipped with a link mechanism with an idle swing function that disables the release operation of the link mechanism, a key cylinder provided on the lower opening/closing body, and a third link mechanism that releases the second lock mechanism in response to the release operation of the key cylinder. It is characterized by

[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 locks the side edge 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 their lower and upper edges, respectively.

In such a state, even if an attempt is made to operate the handle to open the lower opening/closing body, the handle is not in the operating position and is difficult to operate. Even if an attempt is made to release the first lock mechanism by force, the first link mechanism that releases the first lock mechanism will not be able to perform the release operation due to the link mechanism with a missing swing function. , it is impossible to open the lower opening/closing body.

On the other hand, in order to open the upper opening/closing body, the third link mechanism for releasing the key cylinder responds to this, releasing the second locking mechanism, and opening the upper opening/closing body.

When the upper opening/closing body opens, a second link mechanism that is linked to this opening/closing movement is operated to rotate the handle provided on the lower opening/closing body to the operating position. Further, 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 also canceled, and the first link mechanism and the link mechanism with a missing function become linked. Therefore, if the handle, which has been rotated to the operating position, is further rotated in such a state, the operating force of the link mechanism with a missing swing function is transmitted to the first link mechanism, and the first lock mechanism is released. The lower opening/closing body is opened.

[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 7.

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 formed in the bent portion 24B, and an actuating arm 24D extending at right angles is provided in the middle of the abdomen. This second operating lever 24 is connected to the pin 2.
The upper opening/closing body C is always urged to apply a rotational force in the opening direction by the spring 22A wound around the upper opening/closing body C, and is in the position shown by the solid line in FIG. 1 when the upper opening/closing body C is opened.

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. A protruding piece 26B is formed that extends to the bell crank 10 of the first link mechanism and has an engaging surface that can be engaged with the engaging arm 10E of the bell crank 10 of the first link mechanism.

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 a missing swing function.

Further, an escutcheon 30 is provided at the upper center of the lower opening/closing body D, and this escutcheon 30
A handle 34 is housed in the recess 30B.
The handle 34 is connected to the shaft 32, and this shaft 32
It is rotatably supported while being biased in a direction to be flat with the surface of the lower opening/closing body D by a spring 32A wound around the lower opening/closing body D. A lever 34A is integrally formed on the back side of the handle 34, and an arc-shaped long hole 3 centered on the shaft 32 is formed at the tip of the lever 34A.
4B, and the rod holder 25B at one end of the aforementioned actuating rod 25 is engaged with this arcuate elongated hole 34B.

Further, one end of a third operating lever 35 is pivotally supported on the shaft 32, and a locking piece 35A is provided at the midsection of the shaft 32 to engage with the midsection of the lever 34A and limit rotation of the lever 34A in only one direction. ing.

The distal end of the third operating lever 35 is connected to the distal end of the operating arm 24D of the second operating lever 24 by an operating rod 36 via rod holders 36A and 36B, respectively.

Thus, the second operating lever 24, the third operating lever 35, the operating rod 36, and the lever 34A having the arcuate elongated hole 34B constitute the second link mechanism J.

The escutcheon 30 is further provided with a key cylinder 37 movable in the axial direction, and this key cylinder 37 has a rotary lever 38 at its end that rotates integrally with the rotational unlocking operation of the key.
It is equipped with 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 a pin 40A provided on a support portion 30A integrally formed with the escutcheon 30;
It has an engaging surface 40B at one end, and the other end is connected to the actuating rod 42 via a rod holder 42A.

Thus, the bell crank 40 and the actuating rod 42 constitute a third link mechanism K.

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. A projecting 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 via a sliding push rod 90, which will be described later.

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 (see FIG. 6). 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 (fifth (see figure).

Next, the first
The lock mechanism 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 locking mechanism is basically the same as the second locking mechanism 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 the operating rod of the first link mechanism is rotatable about the pin 86A provided on the bracket 84A. A release lever 16A connected to 14A is supported. A striker 88A is fixed to the side edge of the vehicle opening B.

Furthermore, an example suitable as a drive section for the second actuation lever 24 when the upper opening/closing body C is constituted by a thin glass hatch 50 will be explained based on FIG. 4.

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 24 is large, it is preferable to provide a sliding push rod 90 as an intermediate member. For example, the housing 62
A long hole 62B is formed in the bent portion 62A obtained by bending the lower edge of the
The guide pins 92A and 92B fixed to the sliding push rod 90 may be guided through the elongated hole 62B. Of course, if the thickness of the upper opening/closing body C is sufficient, there is no need to provide such an intermediate member.

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, the tailgate D has a handle 3 to open it.
4, the handle 34 is housed in the recess 30B of the escutcheon 30, so it is difficult to do so. The rotational movement is not transmitted to the first linkage mechanism which releases the first locking mechanism E. That is, as shown in FIG. 2, when the handle 34 rotates counterclockwise, the lever 34A of the handle also rotates integrally, but the initial rotation is caused by the engagement between the arcuate long hole 34B and the rod holder 25B. , and is not transmitted to the operating rod 25. From this point, when the handle 34 is further rotated, the first operating lever 23 is rotated clockwise via the operating rod 25, and the swinging lever 26 is rotated clockwise.
push upward. However, at this time, the glass hatch 50 is in a closed state, and the second operating lever 2
4 is rotated counterclockwise by a sliding push rod 90 against the spring 22A (the state shown by the solid line in FIG. 2).
Therefore, the bent end portion 24 of this second operating lever 24
The swing lever 26 fitted into the engagement hole 24C provided in B also rotates clockwise around the pin 23A, and the bell crank 10 forming the first link mechanism
The engaging arm 10E and the projecting piece 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, that is, it will act as an idle swing mechanism, and the tail Gate 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 37 and rotate the turning lever 38 to the unlocked state shown by the solid line in FIG. and,
Push the key cylinder 37 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 clockwise direction shown in the fifth figure. This rotation of the release lever 68 causes the lock plate 66 to rotate counterclockwise in the sixth figure to release the locked state.
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 fourth figure by the spring 22A, and the swinging lever 26 is rotated counterclockwise.
The protruding piece 26 and the engaging arm 10E engage with each other (see FIGS. 1 and 4).

Further, due to the rotation of the second actuation lever 24, the third actuation lever 35 is moved to the shaft 3 via the actuation rod 36.
2 rotations counterclockwise, at this time the locking piece 35
A also rotates the lever 34A. Lever 34
A is the spring 3 due to the play function by the arcuate long hole 34B.
It rotates against only the reaction force of 4A, and the handle 34 is rotated up to the operating position. In addition, the spring 22
The spring force of spring A is set larger than that of spring 32A.

Therefore, when the handle 34 is further rotated from this state, the swing lever 26 is pushed up as described above, but this time, the bell crank 10 is rotated counterclockwise in the fifth figure via the engagement arm 10E. release lever 16 via actuating rods 14A, 14B.
Rotate A and 16B to release the first lock mechanism.

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 activated and the closed state is maintained.

As a result, the second operating lever 24 rotates counterclockwise as shown in the fourth figure, and the third operating lever 35 rotates clockwise, so that the handle 34 is housed in the recess of the escutcheon 30 and becomes flat. Also, the whiff function is restored.

In this state, the key cylinder 37 may be rotated and locked using a key.

According to this embodiment, when the vertical opening/closing body is closed,
The handle forms a flat surface against the outer surface of the lower opening/closing body, and there is no need to form a recess for inserting a hand into the escutcheon, resulting in a good appearance.

[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. Furthermore, since the present invention is equipped with an idle swing function and a handle turning function, it is possible to obtain a vertical opening/closing vehicle door opening/closing device with excellent operability and durability.
