Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open roof device which is movable to a developed position for covering an upper part of a passenger compartment, a retracted position for storing a rear part of a vehicle body.

[0002]

2. Description of the Related Art As a conventional open roof device, the one shown in FIG. 9 has been proposed (Japanese Patent Publication No. 4-4167).
(See the official gazette). That is, the roof 70 is movable to a deployment position A that covers the upper portion of the vehicle compartment R as shown by the solid line and a storage position B that is stored in a storage portion 72 provided at the rear portion of the vehicle body. , A front hard roof 73 and a rear hard roof 74. Both hard roof 7
3, 74 are continuous at the unfolded position A with the inner surface facing the vehicle compartment R side, and the rear edge of the front hard roof 73 is connected to the front edge of the rear hard roof 74 via a folding mechanism 71. .

The folding mechanism 71 includes a first link 75.
And the first link 75 is connected to the bell crank 7
6, via a second link 77, it is pivotally supported by a joint bracket 78 rotatably supported by the rear hard roof 74. One end of a third link 79 is pivotally supported on the joint bracket 78, and the third link 79 is
The other end of is attached to a fixture 80 fixed to the vehicle body.

One end of a roof set bracket 81 is pivotally supported by the fixture 80, and the other end of the roof set bracket 81 is fixed to the lower end of a front hard roof 74. The roof set bracket 81 is pivotally supported by a fifth link 83 via a fourth link 82, and the fifth link 83 is driven by a drive motor 84 in the arrow direction. A gas stay 85 has one end pivotally supported by the vehicle body and the other end pivotally supported by the roof set bracket 81.

In such a structure, in order to move the roof 70 in the deployed position A to the retracted position B, the drive motor 8
When 4 is operated, the fifth link 83 rotates in the arrow direction. Then, the fourth link 82 pulls the roof set bracket 81, and the roof set bracket 81 pivots rearward about the pivot point with respect to the fixture 80. This allows
The rear hard roof 74 also rotates backward together with the roof set bracket 81, and as shown in FIG. 10, the third link 79 also rotates in the same direction.

At this time, the center of rotation of the third link 79 is different from the center of rotation of the roof set bracket 81, which is the center of rotation of the rear hard roof 74, and the distance between pivot points is also different. The joint bracket 78 is rotationally driven along with the rotation. Then, the second link 77 is pulled with the rotation of the joint bracket 78, the bell crank 76 is rotated, and the first link 75 is pulled with the rotation of the bell crank 76.

As a result, the folding mechanism 71 is driven to rotate the front hard roof 73 so that the inner surface thereof faces the inner surface of the rear hard roof 74. Finally, as shown by the chain line in FIG. 9, the roof 10 reaches the storage position B accommodated in the storage portion 72 in a form in which the inner surfaces of both hard roofs 73 and 74 face each other.

[0008]

However, in such a conventional open roof apparatus as described above, when the drive motor 84 starts to operate and the fifth link 83 starts to rotate, the above-mentioned operation starts from that point. So other links 82,7
9, 77, 75, the joint bracket 78, and the bell crank 76 operate, and the folding mechanism 71 starts to be driven. Therefore, as shown in FIG. 10, in the initial stage of movement, the front end 73a of the front hard roof 73 is affected by the rotation of the rear hard roof 74 and takes an arc locus C outside the vehicle interior from the initial position. However, the car room R will soon
A substantially linear trajectory D that descends diagonally in the rear space is taken.

Since the substantially linear locus D is in the vicinity of the occupant's head, when the roof 70 is moved from the deployed position A to the retracted position B, the occupant is made to feel uncomfortable. Will end up. Further, the layout of the interior parts, such as the seat back and the headrest, is required to be arranged in the front so as not to interfere with the substantially linear trajectory D. In addition to being restricted, the space inside the passenger compartment was restricted as a result.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an open roof device in which the movement locus of the front hard roof can be set more outside the vehicle compartment. To do.

[0011]

In order to solve the above problems, the present invention provides a roof that is movable between a deployed position that covers an upper portion of a vehicle compartment and a storage position that is stored in a rear portion of a vehicle body. , The roof is composed of a front hard roof and a rear hard roof that are continuous with the inner surface facing the passenger compartment in the deployed position, and the rear edge of the front hard roof is folded to the front edge of the rear hard roof. Folding means is provided for connection so that the inner surface of the front hard roof is the inner surface of the rear hard roof as the rear hard roof in the deployed position pivots backward and moves to the retracted position. Link means for driving the folding means is provided so as to face the folding means, and delay means for delaying the driving of the folding means by the link means is provided.

[0012]

In the above structure, when the roof in the deployed position is moved to the retracted position, the rear hard roof rotates rearward. At this time, since the delay means delays the driving of the folding means by the link means, even if the rear hard roof starts to rotate rearward, the front hard roof is not folded and continues to the front edge portion of the rear hard roof. With the
Rotate integrally with the rear hard roof. Therefore,
The front edge of the front hard roof takes a locus of movement away from the passenger compartment.

When the rear hard roof further rotates rearward, the linking means drives the folding means, whereby the front hard roof is folded so that the inner surface thereof faces the inner surface of the rear hard roof, and is retracted. Reach the position.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the roof 1 has a developed position A (shown by a solid line) that covers the upper part of the vehicle interior R and a storage position B that is stored in a storage part 2 provided at the rear of the vehicle body.
The front hard roof 3 and the rear hard roof 4 are movable with respect to each other (shown by a chain line), and both hard roofs 3 and 4 are connected to each other with the inner surface facing the vehicle compartment R side at the deployed position A. ing. The front hard roof 3 has a roof outer 5 as shown in FIG. 3, which is a sectional view taken along the line aa of FIG.
And a roof inner 6 connected to the inner surface side of the roof outer 5, and the front end of a lever 9 extending rearward of the vehicle body is fixed to the side of the roof inner 6 by nuts 7 and 7 and bolts 8 and 8. There is.

Further, as shown in FIG. 4, the rear hard roof 4 is also composed of a roof outer 10 and a roof inner 11 joined to the inner surface of the roof outer 10, and is a side portion of the roof inner 11 and close to the front portion. A first bracket 14 is fixed by a nut 12 and a bolt 13. The first bracket 14 is provided with a bolt 16 screwed into a nut 15, and a bush 18 is inserted in the bolt 16 to support the lever 9 in a rotatable state.

In the figure, 46 is a side window glass and 47 is a weather strip, and the pivot point of the lever 9 by the bolt 16 corresponds to the first pivot point P1 shown in FIG. The front end of the first link 20 is pivotally supported above the first pivot point P1 at the rear end of the lever 9 extending rearward from the first pivot point P1. A folding means is formed by the front end portion and the first pivot point P1.

Further, as shown in FIG. 5, the rear hard roof 4 is provided with a second rear portion behind the first bracket 13.
The bracket 21 is fixed. The second bracket 2
1, a bolt 23 screwed into a nut 22 is provided, and a bush 25 is inserted in the bolt 23 so that the bell crank 26 is rotatably supported. Then, on one protrusion 27 of the bell crank 26,
A rear end portion of the first link 20 extending in the front-rear direction is pivotally supported, and an upper end portion of a second link 29 extending in the vertical direction is pivotally supported by the other projecting piece 28. The pivot point of the bell crank 26 by the bolt 23 corresponds to the second pivot point P2 shown in FIG. 1, and the first and second links 2
0, 29 and the bell crank 26 constitute a link means.

On the other hand, as shown in FIG. 6, the sides of the storage section 2 are separated by a side panel 30, and a rear fender panel 31 is arranged outside the side panel 30. A third bracket 32 is fixed to the side panel 30. The third bracket 32 is provided with a bolt 34 screwed into a nut 33. A roof set bracket 36 is rotatably supported by the bolt 34 via a bush 35, and an upper end portion of the roof set bracket 36 is fixed to a lower end portion of the rear hard roof 4. .

Further, a collar 37 is inserted between the bolt 34 and the roof set bracket 36,
The center portion of the first trajectory control link 38 is rotatably supported, and the lower end portion of the first trajectory control link 38 is bent at an obtuse angle (see FIG. 1).
The lower end of 9 is pivotally supported by a bolt 39. Therefore, when the first trajectory control link 38 rotates, the pivot point of the second link 29 moves, and the movement of the second link 29 achieves the delay means as described later. The pivot point of the roof set bracket 36 and the first trajectory control link 38 by the bolt 34 corresponds to the third pivot point P3 shown in FIG.

At the upper end of the first trajectory control link 38, as shown in FIG. 7, a second trajectory control link 40 is provided.
The upper end of is supported by a bolt 41. This second
The trajectory control link 40 extends downward, and its lower end is pivotally supported on one end side from the center of the circular gear 42. An upper end portion of a third trajectory control link 44 is pivotally supported by a bolt 43 at a lower end portion of the roof set bracket 36.
As shown in FIG. 1, the third locus control link 44 extends in parallel with the second locus control link 40, and the lower end portion thereof is on the other end side from the center of the circular gear 42. Second
It is pivotally supported below the lower end of the trajectory control link 40.

In FIG. 1, P4 is the rotation center of the circular gear 42, and the circular gear 42 is the side panel 3
It is adapted to be rotationally driven by a motor 45 fixed to 0.

In this embodiment having the above-mentioned structure, when the roof 1 in the deployed position A is moved to the storage position,
The motor 45 is operated to rotate the circular gear 42 clockwise in FIG. Then, simultaneously with the start of rotation of the circular gear 42, the lower end of the third trajectory control link 44 moves upward while drawing an arc trajectory (arrow a in FIG. 8). Therefore, the lower end portion of the roof set bracket 36 is pushed up by the third trajectory control link 44 (arrow b in the figure), and the roof set bracket 36 rotates about the pivot point P3 while tilting the upper end portion rearward. As a result, the rear hard roof 4 also starts to rotate rearward integrally with the roof set bracket 36.

On the other hand, the lower end of the second locus control link 40 moves downward while drawing an arc locus at the same time when the circular gear 42 starts to rotate (the right part of the arrow c in the figure). Therefore, the upper end of the first trajectory control link 38 is pushed downward by the second trajectory control link 40 (arrow d in the figure), which causes the first trajectory control link 38 to rotate clockwise around the third pivot point P3. Turn to. Therefore, the lower end portion of the second link 29 moves clockwise around the third pivot point P3 and is displaced from immediately below the third pivot point P3.

For this reason, the bell crank 26 is left without being rotationally driven by the second link 29, and the first link 20 also maintains the state along the rear hard roof 4 almost in the same state as in the deployed position A. . Therefore, the lever 9
As a result of maintaining substantially the same state as the deployed position A, the front hard roof 3 also maintains a state of being connected to the front edge portion of the rear hard roof 4 similarly to the deployed position A. Therefore, in this state, the front hard roof 3 rotates integrally with the rear hard roof 4, whereby the front edge portion 3a of the front hard roof 3 is rotated.
Is a predetermined period after the motor 45 starts to rotate (more specifically, the second line drawing the locus of the arrow c as shown in FIG. 8).
Until the lower end of the locus control link 40 reaches the lowermost end of the locus), a locus G that goes upward from the vehicle interior R is taken.

Therefore, the roof 1 is expanded to the unfolded position A in this way.
When changing from the storage position B to the storage position B, the front end portion 3a of the front hard roof 3 moves upward from the vehicle interior R to the outside, so that the passenger does not feel uncomfortable such as pressure. . Further, the layout constraint that the interior parts such as the seat back and the headrest arranged at the rear of the vehicle interior are arranged forward without interfering with the front end edge 3a of the front hard roof 3 is also solved. The restrictions on indoor space are also eliminated.

Then, when the lower end of the second trajectory control link 40 that draws the trajectory of the arrow c reaches the lowermost end of the trajectory,
The lower end of the second trajectory control link 40 starts moving upward on the arc trajectory of arrow c. Therefore, the upper end of the first trajectory control link 38 is pushed upward by the second trajectory control link 40 (arrow e in the figure), which causes the first trajectory control link 38 to move counterclockwise about the third pivot point P3. Rotate in the direction. Therefore, the lower end of the second link 29 has the third
It moves counterclockwise around the pivot point P3 and moves to the third pivot point P.
Move to the position directly below 3.

For this reason, the bell crank 26 is rotationally driven counterclockwise about the second pivot point P2 by the second link 38, and the first link 20 presses the rear end portion of the lever 9. Therefore, the lever 9 starts abrupt rotation in the counterclockwise direction about the first pivot point P1, whereby the front hard roof 3 is folded so that the inner surface faces the inner surface of the rear hard roof 4. go. And the circular gear 4
When 2 rotates about 1/3, the front hard roof 3 and the rear hard roof 4 reach the storage position stored in the storage portion 2 as shown by the chain line.

[0028]

As described above, according to the present invention, the inner surface of the front hard roof is changed to the inner surface of the rear hard roof as the rear hard roof in the deployed position is rotated rearward and moved to the retracted position. The link means for driving the folding means is provided so as to face the above, and the delay means for delaying the driving of the folding means by the link means is provided. Therefore, when the rear hard roof starts to rotate rearward when moving from the deployed position to the retracted position, the front hard roof rotates integrally with the front edge of the rear hard roof. As a result, the front edge of the front hard roof takes a locus that moves away from the vehicle interior.

Therefore, when the roof is moved from the deployed position to the stowed position in this way, the front end of the front hard roof moves upward from the passenger compartment to the outside, so that the occupant does not feel uncomfortable. Will not be generated. Also,
It is also possible to eliminate the restriction on the layout in which interior parts such as seat backs and headrests that are arranged at the rear of the vehicle interior are arranged forward so as not to interfere with the front edge of the front hard roof. It is possible to eliminate the restrictions on the space.
