Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a slide/tilt sunroof device for vehicles such as automobiles.

(Prior Art) Conventionally, there is a slide/tilt type sunroof device for vehicles such as automobiles, as disclosed in Japanese Patent Publication No. 46-5162.

This sunroof device, as shown in FIG.
A panel 3 for opening and closing the opening 2 is supported by a front shoe 4 and a rear slider 5 that are movable along a guide rail, and the front end position below the opening 2 and the rear end position are controlled via these shoes 4 and slider 5. The panel 3 is provided to be slidable back and forth between the fully open position and the rear side of the panel 3 is tilted up and down via a cam mechanism 6 in conjunction with the back and forth movement of the rear slider 5 at the front end position. ing. The cam mechanism 6 has a first cam groove 7 and a second cam groove 8.
The cam plate 9 on the panel 3 side is formed in a continuous manner, and the cam pin 10 on the rear slider 5 side slidably engages in the cam groove 7.8. If the rear slider 5 moves back and forth when the panel 3 is at the front end position, the rear part of the panel 3 will be moved between the tilt-down position A and the fully closed position B due to the cam action of the first cam groove 7 and the cam pin 10. It also moves up and down between the fully closed position B and the tilt-up position C by the cam action of the second cam groove 8 and the cam pin 10.

(Problem to be Solved by the Invention) In the conventional sunroof device, since the cam plate 9 is fixed to the panel 3 side, in order to ensure a sufficient height of the tilt-up position C of the panel 3, it is necessary to install the second cam groove. 8 needs to be made longer in the front-back direction. However, if this is done, the space between the shoe 4 and the slider 5 will be insufficient when tilting up. As a result, the stability of the panel 3 is poor, causing a rattling sound especially when driving on a rough road, and there is a risk of damage to the member.

Therefore, by increasing the inclination angle of the second cam groove 8 of the cam plate 9 as shown by the imaginary line, the distance 12 between the shoe 4 and the slider 5 can be increased, and the stability of the spring 3 can be improved. However, in this case, since the dimensions of the cam plate 9 increase vertically, there is a problem that the entire sunroof device becomes too thick.

In view of these conventional problems, the present invention provides a sunroof device that can improve the stability of the panel in a tilted-up state and can be made thin as a whole.

(Means for Solving the Problems) The present invention provides, as a first means, a panel 26 that opens and closes the opening 12 of the roof 1l, and a panel 26 that is connected to the back and forth movement of the slider 34 when the panel 26 is at the front end position. , slider 3
In the slide/tilt type sunroof device, the rear part of the cam plate 40 of the first cam mechanism 33 is placed on the panel 26 side. It is pivoted so that it can swing up and down,
A second cam mechanism 36 is provided that moves the front side of the cam plate 40 down when moving forward and up when moving backward in conjunction with the back and forth movement of the slider 34.

In addition to the first means, the present invention provides a second means in which the first cam mechanism 3
A link mechanism 65 is provided that raises the cam pin 4l of No. 3 when moving forward and lowers it when moving backward.

(Function) When the slider 34 is advanced when the panel 26 is at the front end position, the second cam mechanism 36 lowers the front side of the cam plate 40. Therefore, as the slider 34 moves forward, the rear side of the panel 26 can be tilted up significantly by the cam action of the first cam mechanism 33.

When the slider 34 is moved backward, the second cam mechanism 36 raises the front part of the cam plate 40.

Therefore, the overall thickness can be reduced, and the slider 3
Panel 2 when tilted up by reducing the amount of forward/backward movement of 4
6 can be improved in stability.

In addition, if the link mechanism 65 is provided, the slider 34
The cam pin 4l of the first cam mechanism 33
moves up and down. Therefore, the overall thickness can be further reduced.

2 is installed. And a pair of left and right shoes 51
．． Among the shoes 52, one shoe 51 is longer in the front-rear direction than the other shoe 52, and a holding hole 54 is formed on the rear end side of the shoe 52, into which a tie piece 53 is fitted so as to be movable up and down. The link support stand 47 can come into contact with the stopper 55 on the guide rail 17 side when the panel 26 moves forward to the front end position, and the timing element 53 can also touch the stopper 55 on the guide rail 17 side at this time, as shown in FIG. It is adapted to be removably engaged with the joint portion 56. On the other hand, on the slider 34 side, there is a timing rod 57 that protrudes toward the link support stand 47 side and overlaps vertically within the guide section 18 of the guide rail 17.
An engaging portion 58 with which the timing element 53 is removably engaged is formed at the front end of the tie rod 57. The timing element 53 and the engaging parts 56 and 58 include
When the timing rod 57 moves forward, the timing element 53 disengages from the engaging part 58 and is engaged with the engaging part 56, and when the timing rod 57 moves backward, the timing element 53 disengages from the engaging part 56 and engages with the engaging part 58. On the other hand, there is a sloped surface on the rear side.

Note that the mounting bracket 31 is provided with an engagement pin 59, and this engagement pin 59 engages the guide portion 18 of the guide rail 17 when the panel 26 is on the rear side of the front end position.
When the panel 26 is at the front end position, it can be removed upwardly through the notch of the guide rail 17. 60 is a sunshade, guide rail 17
is supported and guided by a guide portion 2l. Reference numeral 62 denotes a ceiling interior material, and a mounting plate 63 is fitted to the inner peripheral edge of the opening of this interior material 62, and the mounting plate 63 is fitted with screws 6 to the guide rail l7.
It is attached by 4.

Next, the operation will be explained. The panel 26 is in a tilted-down state with its rear side lower than the roof 11, and is movable in conjunction with the back and forth movement of the slider 35 between the front end position on the side of the opening 12 (see FIG. 7) and the fully open position behind it. It is. In this tilt-down state, as shown in FIG.
Since it is located at the rear end of the cam plate 40, the front side of the cam plate 40 is pulled upward via the tilt link 46 and the cam pin 49. Therefore, the entire sunroof device is thinner vertically and can be moved back and forth in this state.

The opening 12 is completely closed by the spring 26, or the panel 26
When tilting up the slider 34, the drive cable 37 moves the slider 34 forward along the guide rail 17. When the panel 26 reaches the lower front end position of the opening 12 as shown in FIG. 7, the retaining pin 59 corresponds to the notch of the guide rail 17, which allows the rear side of the panel 26 to rise. It becomes a state. Then, when the slider 34 moves further forward (arrow a), the cam pin 41 of the first cam mechanism 33 slides within the first cam groove 38, and due to the cam action between the first cam groove 38 and the cam pin 41, The rear side of the panel 26 is pushed upward, and the weather strip 28 of the panel 26 fits into the opening 12 (see FIG. 1), thereby completely closing the opening 12 of the roof 11.

At this time, as shown in FIG. 10, since the timing element 53 is engaged with the retaining portion 58 of the timing rod 57 of the slider 34, the link support base 4 is moved in conjunction with the slider 34.
7. The tilt link 46 moves forward, and the cam pin 50 slides forward in the cam groove 45. Therefore, due to the cam action of the second cam mechanism 36, the front side of the cam plate 40 is pressed down and lowered relative to the mounting bracket 31.

On the other hand, when fully closed, the link support base 47 comes into contact with the stopper 55 of the guide rail 17, and the timing element 53 of the shoe 51 corresponds to the engaging portion 56 as shown in FIG. Then, when the slider 34 moves further forward, the inclined surface of the retaining part 58 of the timing rod 57 pushes the timing element 53, so that the short lever 53 engages with the retaining part 56 of the guide rail 17, and the link support Since the panel 47 cannot be moved back and forth, the panel 26 is supported in a fully open state.

When the slider 34 is further advanced, the cam pin 4 slides forward in the second cam groove 39, and the cam action of the first cam mechanism 33 causes the rear side of the panel 26 to move upward to the tilt knob position as shown in FIG. Since it is pushed up, the panel 26 is tilted up. At this time, as described above, the front side of the cam vi40 is pushed down by the second cam mechanism 36, so a sufficient tilt-up amount can be secured, and the front shoe 32 and slider 341? The safety of the panel 26 is also good because the distance between the panel 26 and the panel 26 is sufficiently large.

When moving the panel 26 from the tilt-up position to the fully closed position or the fully open position, the slider 34 may be moved rearward, and at this time, each part operates in the opposite direction to that described above.

11 to 15 show a second embodiment of the present invention.

In FIGS. 11 and 13, 65 is a link mechanism,
This is for moving the cam pin 41 of the first cam mechanism 33 up when moving forward and down when moving backward in conjunction with the forward and backward movement of the slider 34. This link mechanism 65 has a first frame attached to the rear end of the slider 34 with a pin 66 so as to be able to rise and fall freely.
a link 67, and a second link 6 which is connected to the tip of the first link 67 by a cam pin 4 of the first cam mechanism 33.
8 and a cam groove 70 formed in the slider 34 so that the cam pin 69 at the tip of the second link 68 engages. The cam groove 70 is U-shaped and opens downward, and the cam pin 6
The first link 67 stands up when 9 is on the rear end side, and falls down when it is on the front end side. The cam pin 69 is connected to the notch 7 of the guide rail l7.
It is possible to move forward or backward when it corresponds to I.

Note that the I unit 67 is provided with a retaining portion 75 that engages with the pin 42 when it is folded down. A regulating pin 59 is provided on the cam plate 40 and the tilt link 46. 72 are provided. The regulation bins 59.72 are guided back and forth by the guide portion 18 of the guide rail 17, and the regulation bins 59.72
and the regulating pin 72 can be removed upwardly from the guide rail 17 when they correspond to the notch 75 and when they correspond to the notch 74, respectively.

In the above structure, when the panel 26 is in the tilted down state, the cam pin 69 is inserted into the cam groove 70 as shown in FIG.
The cam pin 41 is lowered.

When the panel 26 moves forward to the front end position, the cam pin 69 corresponds to the notch 71 of the guide rail 17. Then, when the slider 34 moves forward, the cam pin 69 comes off the guide rail l7 upward through the notch 71, so the cam pin 69 moves relatively backward within the cam groove 70, and again.
It fits into the guide rail 17 from the notch 71 and the cam groove 7
reaches the rear end of 0. As shown in FIG. 11, this movement of the cam pin 69 causes the first link 67 and the second link 68 to stand up, raising the cam pin 4l. Therefore,
The panel 26 changes from the chill l to down state in FIG.
It rises to the fully closed position shown in the figure and closes the opening 12. In addition,
At this time, the regulation bin 59.72 comes off above the guide rail 17 via the notch 75.74.

Subsequently, when the slider 34 is moved further forward, the first link 67 and the second link 68 move forward together with the slider 34 while remaining in an upright state, and the panel 26 is completely moved by the same operation as in the first embodiment. It is tilted up from the closed position to the tilt up position as shown in FIG. 15.

When the slider 34 is moved backward, each part operates in the opposite direction.

By raising and lowering the cam pin 41 of the first cam mechanism 33 using the link mechanism 65 in this manner, the thickness of the entire sunroof device can be further reduced.

In the embodiment, the link mechanism 65 moves the cam pin 41 up and down in order to move the rear part of the panel 26 up and down between the tilt-down position and the fully closed position, but the invention is not limited to this. .

(Effects of the Invention) According to the present invention, the rear part of the cam plate 40 of the first cam mechanism 33 is pivotally supported on the spring 26 side so as to be able to swing vertically, and the slider 3
Since the second cam mechanism 36 is provided which lowers the front side of the cam plate 40 when moving forward and raises it when retreating in conjunction with the forward and backward movement of the panel 4, the stability of the panel 26 in the tilted up state is improved. At the same time, the entire sunroof device can be made thinner.

Further, according to the present invention, in addition to the above structure, the slider 34
The cam pin 41 of the first cam mechanism 33
Since a link mechanism 65 is provided that raises the vehicle when moving forward and lowers the vehicle when retreating, the overall structure can be made even thinner.
