Abstract

PURPOSE:To enable the whole of a panel to be smoothly moved vertically and longitudinally while being kept roughly at a horizontal attitude by providing an interlocking means which allows a timing member to be interlocked with a slider until the panel comes in a lowering attitude with a position restraining means released. CONSTITUTION:The rear section of a timing member 38 is raised up by a timing pin 36 via an interlocking means Y with a slider 6R moved afterward, so that a position restraining means X is thereby released. And next, a front lifting body 9F is moved accompanied by a front slider 6F via the timing member 38 with the front slider 6F moved afterward, so that the front section of the panel 3 is thereby lowered down. The rear section of the panel 3 is lowered down by actuating a rear lifting mechanism 7R with a rear slider 6R moved afterward. As a result, the panel 3 can be lowered down with its horizontal attitude kept roughly as is.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to vehicles such as vehicles such as passenger cars, and is capable of raising and lowering a panel in a substantially horizontal position.
The present invention relates to a sunroof device capable of slidingly opening and closing a roof opening and storing a panel below a rear part of a roof.

[0002]

2. Description of the Related Art A sun roof device of this type can be made thinner when it is applied to an automobile roof with a low vehicle height and a roundness, as compared with a type in which the front part of the panel is not raised or lowered. As a conventional technique, which is useful for ensuring the head clearance, there are those disclosed in JP-A-62-29415 and JP-B-58-32046.

In the former technique, a panel is pivotally supported on an intermediate frame so that the panel can be tilted, and the intermediate frame can be moved up and down and slid rearward. In the latter technique, a cam in front of a connecting link that is driven back and forth is used. The front part of the panel is supported to be lifted up and down, and the guide rail is provided with a cam for moving up and down the rear part of the panel so that the panel can be moved up and down in a horizontal position.

[0004]

In the former technique, since the intermediate frame is required to move the panel up and down, the opening is narrowed and the structure is complicated and the weight is increased. Although it is simple, it is difficult to maintain the posture when the panel is in the closed posture, and rattle easily occurs due to wind pressure.

An object of the present invention is to allow the entire panel to be smoothly moved up and down and moved back and forth in a substantially horizontal posture, and when the panel is in the closed posture A, the sunroof device can be reliably regulated. Is to provide.

[0006]

A concrete means for solving the problems in the present invention is to provide brackets 4 on the lower left and right sides of a panel 3 for opening and closing the opening 2 of the roof 1, and to the left and right side of the opening 2. The guide rail 5 is provided with a slider 6, and front and rear elevating mechanisms 7F and 7R are provided between the bracket 4 and the slider 6 to elevate and lower the panel 3 from the closed posture A to the lowered posture B by moving the slider 6 back and forth. 3 is a sunroof device in which a horizontal movement from a lowering posture B to an opening posture C can be carried together with a slider 6, and the guide rail 5 is positioned relative to the guide rail 5 while the panel 3 is moving up and down. The interlocking body 8 that is immovable and moves together with the slider 6 during the horizontal movement of the panel 3 is provided, and the front lifting mechanism 7F is
The front elevating body 9F that moves together with the slider 6 during the elevating operation of the panel 3 between the bracket 4 and the interlocking body 8, and the bracket 4 is moved up and down with respect to the front elevating body 9F by the forward and backward movement of the front elevating body 9F. First front elevating means 10F and front elevating body 9F
Second front elevating means 11F for elevating and lowering the front elevating body 9F with respect to the interlocking body 8 by forward and backward movements of the interlocking body 8, connecting the timing member 38 to the front elevating body 9F, and moving the panel 3 up and down on the interlocking body 8. There is provided a timing cam body 46 which is sometimes engaged with the guide rail 5 and is engaged with the timing member 38 when the panel 3 is in the closed posture A between the interlocking body 8 and the timing member 38. A position restricting means X for restricting the forward / backward movement of 38 is provided, and the position restricting means X is released between the slider 6 and the timing member 38 by the backward movement of the slider 6 until the panel 3 is in the lowered posture B. That is, interlocking means Y for interlocking with the slider 6 is provided.

[0007]

When the panel 3 is in the closed posture A, the pin 42 is located in the lower front portion of the groove 43 and cannot move back and forth, and the timing member 38 and the front elevating body 9F are restricted from moving back and forth by the position restricting means X. When the slider 6 is moved rearward from this state, the timing pin 36 raises the rear portion of the timing member 38 via the interlocking means Y to move the position regulating means X.
Is released, the pin 42 is moved to the horizontal portion of the groove 43, and the rearward movement of the front slider 6F causes the timing member 38 to move.
The front elevating body 9F moves together with the front slider 6F via the front elevating body 9F via the first front elevating means 10F.
The bracket 4 descends with respect to F, and at the same time, the front elevating body 9F with respect to the interlocking body 8 via the second front elevating means 11F.
Falls, and thus the front of panel 3 falls.

At the same time, the rear portion of the panel 3 is lowered by the operation of the rear lifting mechanism 7R by the rearward movement of the rear slider 6R, so that the panel 3 is in the lowered posture B while maintaining a substantially horizontal posture. When the panel 3 is in the lowered posture B, the timing cam body 46 is engaged with the timing member 38 and at the same time, the engagement with the guide rail 5 is released, and the timing pin 36 is inserted into the groove 4.
Therefore, the rearward movement of the slider 6 after that is engaged at the rear end of the interlock member 0, and the front elevating / lowering body 9F of the interlocking body 8 and the timing member 38.
And the panel 3 is horizontally moved from the lowered posture B to the opened posture C.

The rear portion of the panel 3 descends via the rear elevating means 10R and 11R, and the panel 3 descends to the lowering posture B in a substantially horizontal posture. When the timing member 38 moves rearward and the pin 42 reaches the rear end of the groove 43 at the end of this operation, the engagement opening 41 faces the square hole 45, and the timing cam body 46 becomes engageable with the engagement opening 41.

The subsequent movement of the slider 6F is transmitted to the interlocking body 8 via the timing member 38, and when the interlocking body 8 tries to move rearward, the timing cam body 46 is pushed out from the engaging notch 47 and is moved to the interlocking body 8. The lock of the guide rail 5 is released (FIG. 11), the timing cam body 46 engages with the engagement opening 41, and the interlocking body 8 and the timing member 38 move integrally.

When the slider 6 moves rearward after the lock of the interlocking body 8 is released, the interlocking body 8,
The bracket 4 and the panel 3 move together with the slider 6 to move the panel 3 rearward to an open posture C in which the opening 2 is substantially entirely opened. The movement of the panel 3 from the open posture C to the closed posture A is the reverse operation. Panel 3
Is in the closed posture A, the front portion of the groove 40 is horizontal, and when the slider 6 is moved forward, the timing pin 36 of the front slider 6F only moves in the groove 40, and the front lifting body is moved. 9F and the timing member 38 are not activated, so the front of the panel 3 is immobile. The forward movement of the rear slider 6R moves the rear lifting body 9R forward,
2 The rear part of the panel 3 is lifted through the rear lifting means 10R and 11R. The panel 3 performs the tilt-up operation centering on the first cam pin 49 and moves to the raising posture D (however, the panel 3 passes the overrun state at the initial stage of the tilt-up operation).

When the slider 6 is moved backward from the state where the panel 3 is in the raising posture D and the panel 3 is tilted down, the panel 3 passes through the lowering posture B and descends to the overrun state, and then tilts up slightly. Becomes a closed posture A. As a result, the panel 3 always rises and then the closed posture A
Therefore, the weather strip 22 is prevented from being turned up.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, although the structure in which the panel 3 is tilted from the closed posture A to the raised posture D is shown, the present invention can be applied to a device that does not tilt, and in that case, the groove 40 is formed only in the rearwardly inclined portion and the first cam groove is formed. 15 removes the lifting portion P. Further, the front lifting mechanism 7F of the embodiment may be combined with the rear lifting mechanism of the related art.
