Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for opening and closing an opening formed in the roof of an automobile or the like using a sliding roof.

(Prior Art) This type of sliding roof opening/closing device includes lifting the rear end of the sliding roof above the roof from a closed position where the opening is closed.
After setting the whole body to a tilt position where the rear part is tilted upward,
There is a so-called outer sliding method in which the opening is opened by moving the entire body parallel to the rear while maintaining the rear part tilted upward.

A conventional example of such an outer sliding method is the one shown in Japanese Patent Laid-Open No. 58-93621.

In this conventional device, a slider is slidably provided on a guide rail that is fixed to the side edge of the roof opening and faces in the front-rear direction, and the front end of the slider has a
The front end of the bracket that supports the sliding roof is pivoted about a left-right axis, and the middle part of the bracket is raised and lowered by a lifting device installed in the center of the slider, thereby raising and lowering the sliding roof. The sliding roof can be tilted between an upwardly tilted rear position and a horizontal position, and the sliding roof can be moved in the front and back direction by moving a slider back and forth using a drive means provided in the roof. It's getting old.

(Problems to be Solved by the Invention) In the conventional device described above, the front end of the bracket is simply pivoted to the front end of the slider with a left-right axis, so that the bracket and sliding The center of rotation of the roof is behind the front edge of the sliding roof and below the top surface of the roof. Therefore, when the sliding roof is in the tilt position, the front edge of the sliding roof is below the top surface of the roof. As a result, the sealing performance at the front end of the sliding roof deteriorates, and in this state, if the sliding roof is moved parallel to the rear with the slider, the middle part of the sliding roof will immediately close to the opening of the roof. There is a problem that the opening cannot be opened sufficiently because the opening touches the rear edge of the opening.

Also, when the sliding roof is in the tilt position, only a portion of the sealing material provided on both sides of the sliding roof locally contacts the side edges of the opening, and in that state, the sliding roof is rotated several times. If the sealing material is moved back and forth, the above-mentioned portion of the sealing material will be extremely worn, and there will be problems such as loss of sealing performance in a short period of time.

(Means for solving the problem) In the present invention, in order to solve the above problem, a guide rail facing in the front and rear direction is fixed to the side edge of the opening formed in the roof, and the guide rail is slidable on the guide rail. The front end of the bracket that supports the sliding roof is connected to the front end of the slider attached to the slider with a left-right pivot, and the middle part of the bracket can be raised and lowered by the lifting device installed in the center of the slider. In a sliding roof opening/closing device that allows the sliding roof to be tilted between a rear upwardly inclined state and a horizontal state,
A raised part including a front wall and a side wall is provided at the front end of the slider, and an aerial point located above the roof and almost directly above the front end of the slider is provided on the rear surface of the front wall of the raised part. A rack having an arc shape at the center is provided, and a long hole parallel to the rack is provided in the side wall, and the front end of the bracket is engaged with the rack, so that when the sliding roof is in a horizontal state, the rack A pinion is connected to the rack for moving the sliding roof forward of the pivot shaft and rotating the sliding roof about an imaginary point above the rack when the rack moves downward and is in a tilted state. It is characterized in that a pivot shaft is provided at the center of the pinion and is slidably fitted into the elongated hole.

(Function) In the present invention, from the state where the sliding roof is in the fully closed position where it closes the roof opening,
When the middle part of the bracket is lifted by the lifting device, the pinion rotates around the pivot and rolls upward along the rack surface, and the pivot moves upward in the elongated hole accordingly. I am made to do so.

In this way, by raising the pivot within the elongated hole, when the sliding roof is placed in the tilt position, the entire sliding roof can float above the upper surface of the roof.

Therefore, even if the slider is moved rearward from this tilted state to open the sliding roof, the sealing member on the side edge of the sliding roof will not rub against the side edge of the roof opening.

When the middle part of the bracket is lowered by the lifting device from the sliding roof in the tilt position, the front end of the bracket is lowered and the entire bracket is lowered, returning to the fully closed position.
