Description

TECHNICAL FIELD The present invention relates to an improvement of a sunroof device for vehicles, ships, etc., particularly a tilt-and-slide type sunroof device.

2. Description of the Related Art In a sunroof device for a vehicle, a ship, etc., wear and tear due to sliding contact of a weather strip between the front and rear edges of the roof fenestration part and the front and rear edges of a slide panel at the initial stage of tilting up and tilting down, In order to prevent the deformation, as shown in FIG. 6, the long hole B at the front end of the panel support bracket A fixed to the slide panel is fitted to the tilt axis D of the front shoe C of the tilt and slide device. At the same time, the front shoe C and the panel support bracket A are connected by a link E, and a spring F that constantly applies a rotational force in the tilt axis D direction is engaged with the link E, so that the tilt-up and tilt-down are initially performed. , A mechanism for moving the slide panel back and forth within the range of the long hole B is adopted.

Further, as shown in FIG. 7, guide grooves H and I are formed in a fixing member G on the vehicle body side such as a roof support bracket, and the guide grooves I are inclined upward and rearward. The guide pin K of the front shoe, which is rotatably engaged with the support bracket J of the slide panel, is fitted into I, and the slide panel is moved within the tilt range of the guide groove I at the initial stage of tilt-up and tilt-down. A mechanism to move it back and forth is also adopted.

Problems to be Solved by the Invention In the above-described conventional mechanism shown in FIG. 6, not only the components such as the link E and the spring F are required in addition to the tilt-and-slide mechanism, but also the tilt-and-slide device is used. Due to the relationship, there are various design restrictions on the length of the link E, so that the distance L between the tilt axis D and the connecting point M of the link E becomes short, which causes the above-described forward and backward movement of the slide panel in the initial tilt operation. There is a problem that backlash is likely to occur and there is no freedom in designing the movement trajectory.

The one shown in FIG. 7 also requires the fixing member G, which increases the number of parts and increases the weight, and since the fixing member G is fixed to the vehicle body, it cannot be used as the guide pin K of the front shoe of the tilt-and-slide device. However, there is a problem in that the fixing member G and the tilt-and-slide device need to be assembled with high accuracy, which causes a decrease in production efficiency.

SUMMARY OF THE INVENTION In view of the above-mentioned current situation, the present invention minimizes the increase in the number of parts, allows the movement trajectory of the slide panel at the initial stage of tilt-up and tilt-down to be freely designed, and further, to the conventional tilt-and-slide device. Easy to apply, not only rattling is unlikely to occur when the slide panel is moved up and down, and since the structure is incorporated in the tilt-and-slide device, no particular assembling precision with the vehicle body side parts is required. An object of the present invention is to provide a sunroof device provided with a slide panel moving mechanism in the initial stage of tilting up and down.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a panel support bracket fixed to the indoor side of a slide panel, the front end of the panel support bracket being provided rearward of the front end of the slide panel. A long hole is formed at the front end of the panel support bracket in the length direction of the slide panel, and the long hole is slidably fitted to the tilt shaft of the front shoe of the tilt and slide device. In the panel support bracket, a long groove is formed in the rear of the long hole in a substantially vertical direction, and the long groove is slidably fitted to a guide pin of the front shoe.
The long groove is located outside the track where the upper part of the groove moves away from the center of rotation, and the lower part of the groove approaches the center of rotation with respect to the virtual rotation track of the guide pin about the tilt axis. And the center of rotation of the slide panel located behind the front end of the slide panel and on the indoor side is movable forward and backward in accordance with tilt up and tilt down of the slide panel. ing.

The present invention has the above-described configuration, and when the tilt-up operation of the tilt-and-slide device is started, the panel support bracket is rotated upward with the tilt axis of the front shoe, which is a fixed position, as the rotation center. At the same time, the long groove formed in the bracket starts moving upward with respect to the guide pin of the front shoe. The lower part of the long groove is located inside the track near the tilt axis, which is the center of rotation, with respect to the virtual rotation path of the guide pin about the tilt axis, and the guide pin is located on the front shoe that occupies a fixed position. Since it is attached and the position is immovable, the panel support bracket is displaced rearward along with the displacement of the groove lower part of the long groove by the amount of the positional deviation between the virtual rotation locus and the groove lower part, and this displacement is , Is smoothly performed by a floating gap between the long hole at the front end of the panel support bracket and the tilt shaft, and a gap is formed between the front edge of the roof window opening and the front edge of the slide panel when tilting up, Sliding contact with friction of the weather strip is prevented.

When tilting down, the upper part of the long groove of the panel support bracket is located outside the virtual rotation path away from the tilt axis, which is the center of rotation, so that the virtual rotation is reversed, as opposed to when tilting up. The panel support bracket is moved forward by the amount of the positional deviation between the track and the upper part of the groove, and a gap is formed between the trailing edge of the roof fenestration and the trailing edge of the slide panel. Contact is prevented.

The rotation locus of the slide panel at the initial stage of tilt-up and tilt-down described above can be freely designed by the shape of the long groove formed in the panel support bracket.

Structurally, it suffices to form a long groove in a panel support bracket that has been conventionally provided and to provide a guide pin to be fitted into the long groove to the front shoe, and the only additional component is the guide pin. Since it is incorporated in the tilt-and-slide device, incorporation into a vehicle or the like is sufficient only by incorporating the device, and no particular increase in the assembling accuracy is required, and it is also necessary to change the design of the tilt-and-slide device. Absent.

Embodiment FIG. 1 to FIG. 5 show an embodiment.

FIG. 1 is an exploded perspective view of a tilt-and-slide device to which the present invention is applied, in which a driving device and a guide rail of the device are omitted, and a tilt-and-slide device arranged on the right side of a slide panel is shown. Only the slide device is shown.

The front end 3 of the panel support bracket 2 fixed to the lower surface of the slide panel 1 is provided with a long hole 4 which is long in the length direction of the slide panel 1 and slides on a tilt shaft 6 of a front shoe 5 of the tilt and slide device. It is movably fitted.

The panel support bracket 2 in the illustrated example is a slide panel 1
When the slide panel 1 occupies the position for closing the roof fenestration 8 and the position for tilting up or tilting down, it has a side wall 7 provided in the longitudinal direction of The side wall 7 corresponding to the existing front shoe 5 is provided with a long groove 10 which is long in the vertical direction, and a guide pin 11 supported by the front shoe 5 is slidably fitted in the long groove 10. .

The long groove 10 in the illustrated example is formed in an arc shape that extends upward from the lower end of the side wall 7, but as will be described later, it is designed in a desired shape in accordance with the vertical movement trajectory to be given to the slide panel 1. It is what is done.

As shown in FIG. 3, the center line N-O of the long groove 10 is the upper part of the groove with respect to the virtual rotation locus P-Q of the guide pin 11 with the tilt shaft 6 as the rotation center. 12 is located outside the locus P-Q moving away from the center of rotation,
Are located inside the turning locus P-Q.

In the rear portion of the side wall 7 of the panel support bracket 2,
A V-shaped guide groove 14 having a long front portion and a short rear portion is formed, and a guide block 15 is fixed to the side of the opening position of the guide groove 14 with a space therebetween to face the guide groove 14. As a result, a V-shaped guide groove 16 having a different bending angle from the groove 14 is formed.

On the other hand, the guide rail 9 is driven by a drive device (not shown).
A link 19 rotatably supported by a rear shoe 18 that is slid back and forth along a drive cable 17 is rotatably inserted in a space between the side plate 7 of the panel support bracket 2 and the guide block 15. , The guide pins 20 and 21 projecting from both sides of the front part of the link 19 in different phases,
It is slidably fitted in the corresponding guide groove 14 and guide groove 16.

A holder 23 of a rain channel 22 is connected to the front shoe 5 by a connecting rod 24.

Reference numeral 25 in FIG. 1 is a lift guide for the slide panel 1,
Reference numeral 26 is a stopper for holding the front shoe 5 in a fixed position on the guide rail 9.

FIG. 2 shows a state in which the slide panel 1 closes the roof fenestration 8, and the guide pin 11 occupies the position shown in FIG.

When the rear shoe 18 starts to move forward from the state shown in FIG. 2 by the operation of a drive device (not shown), the link 19 guides the guide pins 20 and 21 corresponding to the distance between the two pins. While moving in the gap between the grooves 14 and 16, it rotates in the clockwise direction to start tilting up the slide panel 1 via the panel support bracket 2.

Due to the start of this tilt-up, the panel support bracket 2 rotates in the direction of arrow S as shown in FIG.
As shown in FIG. 4, the front shoe 5 is held at a fixed position and has not started sliding yet, so the tilt shaft 6 and the guide pin 11 maintain the fixed position.

By rotating the panel support bracket 2 in the direction of arrow S with respect to the guide pin 11 which maintains the fixed position, the long groove of the side wall 7 is formed.
10 also moves up in the direction of arrow S, and the lower part 13 of the groove is the guide pin 11
The center line N-O of the long groove 10 is guided to the lower part of the groove.
In FIG. 13, since the guide pin 11 is positioned inside the virtual rotation path PQ of the guide pin 11, the upper surface 27 of the panel support bracket 2 rotates to the position of the line T in FIG. 3, for example. Then, the bracket 2 is retracted in the direction of arrow U by the length l1, and accordingly, the center of rotation of the slide panel 1 existing in the elongated hole 4 around the tilt shaft 6 is also retracted in the direction of arrow U. , A weather strip 30 between the front edge 28 of the roof fenestration 8 and the front edge 29 of the slide panel 1.
Has a gap with respect to the front edge 28, and wear of the weather strip 30 is prevented.

Conversely, when the rear shoe 18 is retracted in the direction of arrow V in FIG. 2, the panel support bracket 2 is rotated in the direction of arrow W in FIGS. 3 and 5 and tilted down. Since the tilt shaft 6 and the guide pin 11 are kept in a fixed position, the groove upper part 12 of the long groove 10 is guided to the guide pin 11, so that, for example, as shown in FIG. Is rotated to the position of the line X, the bracket 2 is advanced in the direction of the arrow Y by the length l2,
Therefore, the center of rotation of the slide panel 1 is also advanced in the direction of the arrow Y, and the weather strip 33 between the rear edge 31 of the roof window opening 8 and the rear edge 32 of the slide panel 1 is the rear edge.
There will be a gap for 31 weather strips
33 wear is prevented.

Since the sliding contact of the weather strip is large at the front edge portion of the roof fenestration portion 8 when tilting up, and the sliding contact of the weather strip becomes large at the rear edge of the roof fenestration portion 8 when reverse tilting down is performed. The wear of the weather strip is prevented by the above-described operation.

From the state shown in FIG. 5, by continuing the rearward movement of the rear shoe 18 in the direction of arrow V, the slide panel 1 is housed in the housing 34 together with the rain channel 22, and the roof window part 8 is fully opened. .

As is clear from the above description, the movement path and the movement amount of the slide panel 1 in the front-rear direction at the time of tilting up and tilting down are restricted by the shape of the long groove 10. Therefore, by selecting the shape, the slide panel It is possible to freely set the movement trajectory and the movement amount in the front-rear direction in the initial stage of the tilt-up and tilt-down of No. 1.

As described above, the mechanism for moving the slide panel 1 back and forth at the initial stage of tilt-up and tilt-down is the guide pin 11 of the front shoe 5 and the long groove 10 of the panel support bracket 2.
The two are engaged with each other by rigid bodies without the interposition of a spring or the like, and engagement without rattling can be obtained. The positions of the guide pin 11 and the long groove 10 are selected within the length range of the front shoe 5. Because it can, tilt shaft 6 and guide pin 11
The distance between and can be set long enough.

Advantageous Effects of Invention The present invention has the above-described structure and operation. Even though the weather strip of the sunroof device can be prevented from being worn or deformed, the number of parts is increased only by increasing the number of guide pins. And the shape of the long groove of the panel support bracket can be selected to freely design the movement path and movement distance of the slide panel at the initial stage of tilt-up and tilt-down. The front end of the panel can substantially not move in the front-rear direction, and the front end of the slide panel can substantially move into the weather strip when tilting down.

Further, since a guide pin is provided on the front shoe and a long groove cooperating with the guide pin may be opened in the panel support bracket, there is an effect that it can be immediately applied to a conventional tilt-and-slide type sunroof device.

Furthermore, since the guide pin and the long groove are structured to be incorporated in the tilt-and-slide device, there is no need for an extra assembly process between the parts on the vehicle body side and the assembly accuracy, and the sunroof device Despite the ability to improve performance, it also has the effect of suppressing an increase in manufacturing cost.
