Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a closure system in which the roof opening is closed by pivoting the vanes around an axis perpendicular to the longitudinal direction of the vehicle (lateral axis) so that the vanes abut against each other without any gaps. The present invention relates to a motor vehicle roof with a series of slats that can be placed in a position or in an outwardly swiveled position.

In known car roofs of this kind (UK patent no.
No. 463048), the pivot axis of the vane is fixed.

The object of the invention is to construct a motor vehicle roof of the type mentioned at the outset in such a way that the roof opening can be completely opened, as in the case of conventional sliding roofs.

This object is achieved according to the invention in that the vane in the outwardly pivoted position can also be slid and brought together in the area of the leading edge of the roof opening. That is, in the case of the automobile roof according to the present invention, the pivot axes of the vanes other than the frontmost vane can be moved in the longitudinal direction of the vehicle. In the assembled state, the slats leave at least a substantial portion of the roof opening open. In this case, the collected bundle of slats serves as a windbreak. That is, according to the automobile roof according to the present invention, the functions conventionally achieved by combining a sliding roof and a windbreak (for example, West German Publication No. 2,644,848) can be achieved relatively easily.

It can be slid vertically within a guide provided on the upper longitudinal beam of the side wall of the vehicle, and is movable in the longitudinal direction of the vehicle relative to the vehicle body, and when the canopy is opened, the windshield glass is placed in a position to deflect the wind. A canopy for an observation car installed at a height of
issue). However, in this case the roof opening
Closed by a canopy separate from the windshield.
The windshields cannot be placed in a position where they abut each other and close the roof opening. When closing the canopy, the windshield is slid together and stored in the front fixed hood.

For stability reasons, the slats are mounted on guide rails extending on both sides of the roof opening, which are fixed to the roof.
so as to be slidable in the direction of the longitudinal axis of the guide rail,
If you guide them, it will be useful.

In a further development of the invention, the slats are further arranged so as to be slidable in the direction of the longitudinal axis of the slats in guide grooves which extend on both sides of the roof opening and are movable for pivoting the slats. , has been guided. In this case, the engagement points between each vane and the guide rail and guide groove are eccentric with respect to each other. The construction of the blade pivoting mechanism is thus particularly simple.

It is expedient if the guide rail forms a control groove in which an essentially horizontally extending sliding jaw shaft, which is connected to the vane, engages. Alternatively, the sliding jaw shaft can be fixed to the vane and rotatably and slidably journalled in the control groove.

Preferably, on both sides of the vane there is provided in each case a pivot lever with a free end, preferably spherical, which engages in the corresponding guide groove. A structurally simple solution is obtained if the guide groove is formed from a shape that can be pivoted about an axis parallel to the longitudinal axis of the guide groove. However, in principle it is also possible to have a linear displacement of the guide groove in an essentially vertical direction.

To move the slats, two pressure-resistant drive cables connected to a common drive pinion can be provided in a manner known in conventional sliding roofs. In this case, each side of the roof opening has a linkage serving to pivot the pivotable profile in question, each operatively connected to a drive cable and slidable in the sliding direction of the slats. It would be useful to provide a guide slider. Both sides of the rearmost vane can each be connected to a sliding slide which can be slid to some extent in the sliding direction of the vane relative to the corresponding guide slide. The guide slide and the sliding slide are essentially the sliding movement of the guide slide that is necessary to pivot the vane between a closed position and an outwardly pivoted position for movement in the sliding direction of the vane. It is advantageous if they are interconnected via equal-movement drive joints.

If each vane except the rearmost vane is configured so that it is driven by the respective rear vane during sliding, the number of required drive elements is particularly reduced.
In this case, it may be expedient to connect the vanes to one another, preferably by means of flexible and/or longitudinally extensible connecting elements. Preferably, a stop is provided which determines the final position of the pivot axis of the vane during relative movement of the vane, so that the vane assumes a precisely defined position relative to the roof opening when pivoted into the closed position. The stopper comprises, in particular, a disc which is concentric with the pivot axis of the vane and has a different diameter for each vane, and which is provided laterally in the guide rail following the control groove and has a correspondingly varying diameter; and a control groove that cooperates with the control groove.

The invention will now be described with reference to preferred embodiments shown in the accompanying drawings.

In FIG. 1, the fixed roof section 10 includes four
A roof opening 11 is formed which can be closed by three slats 12, 13, 14, 15. The number of slats is, of course, not limited to four, but can be adapted to the requirements in question and the dimensions of the roof opening. In the closed position, the slats 12 to 15 abut one another without gaps and provide the necessary sealing of the roof.

The structure of the vanes and associated guiding and driving elements is
Since it is the same for both sides of the slat, below:
Only one side of the structure will be explained.

Guide rails 16, which are fixed to the roof, extend on both sides of the roof opening 11. The illustrated embodiment includes:
Said guide rail is attached to an outwardly facing flange 17 of the roof frame 18. The roof frame 18 surrounds the roof opening 11 and has a rainwater gutter 19.
form. The guide rail 16 has blade plates 12 to 1.
5 and forms a control groove 20 in which an essentially horizontally extending sliding jaw shaft 21 engages. In the illustrated embodiment, the vanes 12-15 include a sliding jaw shaft 2.
1 is provided with a rotatably supported projection 22.
Alternatively, the sliding jaw shaft can be fixed to the vane and rotatably and slidably journalled in the control grooves 20 on both sides of the roof opening 11.

On both sides of each vane plate 12 to 15, a spherical free end 25 is provided which engages with a guide groove 26 of a pivotable shaped body 27.
A pivot lever 24 is provided which has a swivel lever 24. The axis of the sliding jaw shaft 21 is eccentric with respect to the end 25 of the pivot lever 24. The profile 27 extends essentially over the entire length of the roof opening 11 and can be pivoted about an axis 28 parallel to the longitudinal axis of the guide groove 26 . The spring or springs 29 act to urge each of the two shapes 27 into a position (FIG. 3) corresponding to the outwardly pivoted position of the vanes 12-15.
The spring 29 engages on the one hand in the end 30 of the profile 27 facing away from the guide groove 26 and on the other hand in the roof frame 18 . As can be seen from the drawing, the profile 27 lies on its upper and lower sides in a chamber formed by the fixed roof part 10 and the roof frame 18, respectively. Rearmost blade plate 15
In the region of the pivot axis, a guide slide 32 is provided below the vane. The guide slider 32 is a rail 3 fixed to a ridge 36 of the roof frame 18.
It is guided in the guide groove 34 of No. 5. In this case, a sliding shoe 37 coupled to the guide slider 32 slides within the guide groove 34 . Groove 34 is similar to grooves 20 and 26
extends parallel to. A link mechanism 38 is provided on the upper surface of the guide slider 32 and comes into contact with the lower surface of the shaped body 27 in question. In the area of the front edge 40 of the roof opening, below the fixed roof part 10, a drive pinion 41 is provided which engages with two pressure-resistant drive cables 42, 43. For this reason, the outer surface of the drive cable has, over at least part of its length,
A screw is provided in a known manner. In the illustrated embodiment, the drive pinion 41 is manually actuated via a collapsible crank 44. Of course, instead of the crank 44, a power drive (in particular an electric drive) can also be provided. One drive cable 42 is operatively connected to the guide slide 32 on one side of the roof opening 11, while another drive cable 43 is operatively connected to the guide slide 32 on the other side of the roof opening. Drive cables 42, 43
slides in the cable groove 45 formed by the guide rail 16.

The guide slider 32 includes a sliding slider 46.
It is pivoted so that it can move to some extent in the sliding direction of the vane. The sliding slider 46 is connected to the rearmost vane plate 15 via the sliding jaw shaft 21. The preload spring 47 serves to pull the sliding slide 46 rearwardly with respect to the guide slide 32. In order to limit the relative movement of the two slides 32, 46, the guide slide 32 is provided with a front stop 49 and a rear stop 50. The stop 49 cooperates with the leading edge 51 of the sliding slide 46, while the stop 50 can be engaged with the edge of the sliding slide 46 (FIG. 4). Both sides stopper 4
9, 50 are drives which, in cooperation with the edges 51, 52, effect a movement essentially equal to the sliding movement of the guide slider necessary to pivot the vane between the closed position and the outward pivoting position. Configure the fitting. Furthermore, the rear edge 53 of the sliding slider 46 is connected to a fixed stopper 54.
work together with

The vanes 12-15 are connected via a flexible connecting member 56, which is preferably also extendable in the longitudinal direction. The coupling member 56 is connected to the sliding slider 46
It is expedient to engage the end 57 (FIGS. 2 and 3) of the sliding jaw shaft 21 which projects outwardly from the jaw.

Front edge 58 and rear edge 59 of vanes 12 to 15
are thinner and overlap each other in the closed position (Figs. 4 and 5). The tip of the leading edge 58 is slightly curved upwards, thus forming a rainwater groove 60 extending perpendicular to the longitudinal direction of the vehicle. The intruding water flows from the rainwater gutter 60 to the roof frame 1.
It flows out into a rainwater ditch 19 formed by 8. The trailing edge 59 is provided with a sealing strip 61.
In the closed position of the slats, said sealing slips abut, respectively, a beveled surface 62 of the inner next slat and a corresponding surface 63 of the roof frame 18 (FIG. 4).

The sliding jaw shaft 21 is provided with a roller or disk 65 whose diameter is changed stepwise for each blade. In this case, the diameter of the disc 65 of the vane plate 15 is the minimum, and the diameter of the disc 65 of the vane plate 13 is the maximum. The disc 65 slides in control grooves 66, 67, 68 of correspondingly varying diameter in the guide rail 16. In this case, the transition between the control grooves 67, 68 forms a stop for the disc 65 of the vane 13. The disc 65 of the vane 14 rests at the transition point of the control grooves 66, 67. Control groove 66
The end of the blade 15 forms a stop for the disc 65 of the vane 15.

When the drive cable 42 is pulled forward by the drive pinion 41 from the closed position of the slats (FIGS. 4 and 5), the guide slide 32 moves with the cable. The shaped body 27 is moved by the link mechanism 38.
It is pivoted about axis 28 from the position of FIG. 2 to the position of FIG. 3. At this time, the guide groove 26 rises together with the spherical end 25 of the pivot lever 24 of the blade plates 12-15. When the rear stopper 50 of the guide slider 32 reaches the edge 52 of the sliding slider 46,
The vanes 12-15 are pivoted about a pivot axis determined by the sliding jaw axis 21 to reach the outward pivot position of FIG. When the drive cable 42 is advanced further, the sliding slide 46 is moved along with it by the guide slide 32. The rotated blade plate 15 is
It is slid forward. When the vane 15 hits the pivoted vane 14, the vane 14 is correspondingly driven. The slats are thus gathered in the area of the leading edge of the roof opening (FIG. 7).

Also on the other side of the slat, the drive cable 42
Similarly, the drive cable 43 first moves the guide slider 32 and then the sliding slider 46 .

On the other hand, if the drive cable is slid backward in the cable groove 45 from the vane position shown in FIG.
Due to the preload spring 47, both sliders 32, 46 move rearward while the stopper 50 remains engaged with the edge 52. The vanes 12-15 thus remain in the outwardly pivoted position. A sliding slide 46 drives the slat 15, which, via the coupling member 56, moves the slats 14, 13 in the direction of the trailing edge of the roof opening 11. Feather plate 12~
The pivot axis of 15 remains in the position determined by the stop consisting of the disc 65 and the control grooves 66-68. Since the coupling member 56 is telescopic, unavoidable dimensional tolerances are often compensated for. When the pivot axis of the vane assumes the final position determined by the stops 65-68, i.e. in the operating state shown in FIG.
hits the fixed stopper 54. Sliding slider 4
6 stops. On the other hand, when the drive cable 42 is further moved rearward, only the guide slider 32 slides, and the front stopper 49 of the guide slider 32 comes into contact with the front edge 51 of the sliding slider 46 under the action of the spring 47. . At this time, the shaped body 27
9 is moved from the position of FIG. 3 to the position of FIG. 2. When the guide groove 26 is lowered, the vanes 12 to 15 are pivoted to the pivot position shown in FIGS. 4 and 5.

Instead of flexible coupling members 56, rigid coupling members (eg, hooks) can also be used.
When the disks are assembled (7th
), each abuts the top surface of the next slat,
A cushion (not shown) can be provided to provide greater rigidity to the slat bundle and to prevent noise generation.

Unlike conventional sliding roofs with rigid sliding covers, the above-mentioned slat-shaped roofs can be provided with roof openings larger than 50% of the roof length, which means that rigid sliding roofs This is particularly important in the case of roofs of sports cars, trucks, etc., where only a very short roof opening can be opened when using a
