Background of the Invention
1. Field of the Invention
The present invention relates to automobile roof vents and sliding roof structures, and in particular to vents or sliding roof panel structures in which the rear edge of the vent panel or sliding roof panel is pivotable upwardly out of the roof opening.
2. Description of the Prior Art
Vent panels and sliding roof panels which are openable by pivoting their rear edges upwardly out of the roof opening are known from various prior art teachings. Also known are sliding roof structures in which the sliding roof panel is openable in two modes, either by pivoting the rear edge of the panel upwardly or by pivoting it downwardly and retracting the panel under the stationary roof portion to create an opening at the front edge of the panel.
In connection with upwardly pivoting panels, especially in cases in which a large pivoting angle is possible, it was found to be necessary to reduce the pivoting angle, whenever the vehicle travelled at higher speeds, because wind and/or water spray would enter through the lateral gap under the raised side portions of the roof panel. This necessity of lowering the roof panel to a very small pivoting angle represents a disadvantage of presently known vents and sliding roof structures.
Summary of the Invention
It is the purpose of the present invention to eliminate the aforementioned disadvantage by suggesting a simple, improved structure for vent panels and sliding roof panels in which the lateral entry of an air stream or of water spray is prevented, without the need for unnecessarily reducing the opening angle of the roof panel.
In order to meet this objective, the invention suggests an upwardly pivotable roof panel, usable as a vent panel or as a retracting sliding roof panel, which comprises a vertically arranged shutter member on each side of the panel which, when the latter is opened, at least partially covers the triangular lateral gap between the panel and the edge of the roof opening.
A preferred embodiment of the invention features lateral shutters which are pivotably attached to the roof panel and which can be retracted in relation to the latter, when it is desired to inwardly open the sliding roof panel, for example.
An additional advantageous feature of the invention relates to a lateral shutter arrangement in which the shutters are spring-biased downwardly into their extended position, which latter is determined by an abutment. In the case of a retractable sliding roof, when the rear edge of the sliding roof panel is to be lowered for inward opening, the spring-biased shutter members are automatically retracted, as the sliding roof panel is lowered. The lowered panel can then be retracted under the stationary roof portion in the usual manner.
Brief Description of the Drawings
Further special features and advantages of the invention will become apparent from the description following below, when taken together with the accompanying drawings which illustrate, by way of example, an embodiment of the invention, represented in the various figures as follows:
FIG. 1 shows, within a longitudinal cross section through a roof structure, an elevational end view of a closed roof panel structure embodying the invention;
FIG. 2 shows the structure of FIG. 1 in its upwardly pivoted open position;
FIG. 3 shows the roof structure of FIG. 1 in its downwardly pivoted position prior to retraction;
FIG. 4 is a partial transverse cross section through the structure of FIG. 3 along line IV--IV thereof; and
FIG. 5 is a similar partial transverse cross section through the structure of FIG. 2 along line V--V thereof.
FIG. 6 shows a section corresponding to FIG. 3, with the slide cover partly slid backward and underneath the stationary top element.
Description of the Preferred Embodiment
As shown on FIGS. 1 to 6 the rigid cover 3 is provided near its front edge on each side with a slide flange 2, pivotable about a horizontal shaft 2a that extends transversely to the longitudinal direction of the vehicle. The slide flange 2 is mounted on the lower end of a vertical arm 3a which is fastened to the cover 3. Slide flange 2 rests, longitudinally displaceable, in a guide rail 15. At each lateral edge of the cover 3 is provided a downward extending fixed blind or capping 9. On the inside of each fixed capping 9 is pivotally mounted a movable shutter or capping 4. The movable cappings 4 are pivotable in vertical planes and relative to the fixed cappings 9, about pivot pins 5 at the front ends of the fixed cappings 9.
The natural tendency of each pivotable capping 4 to pivot downward under its own weight is augmented by a spiral spring 6. Spring 6 presses, in the open position, shown in FIG. 2, of cover 3, the rear end 4a of capping 4 against a stop 7 at the rear end of each fixed capping. A closed or lowered cover 3 according to FIGS. 1, 4 and 6, spring 6 presses movable capping 4 against the bottom of a rain gutter 8. In both cases, a rattling of the pivotable capping 4 is prevented by the effect of spring 6.
In the open position of cover 3 as shown on FIG. 2, the fixed capping 9, jointly with the downward protruding area of pivotable capping 4 closes approximately the lateral rectangular gap produced between the upward pivoted cover 3 and the edge of the top opening 1a, whereby rain- or spray-water is prevented from entering laterally through the top opening 1a to the inside of the car. As shown on FIGS. 5 and 4, the rear end of each fixed capping 9 is U-shape bent so as to form, on one side stop 7 and, on the other side a guide for the rear end 4a of the pivotable capping 4, between capping 9 and the inner side 10.
When the cover 3 is closed the pivotable capping 4 abuts against the wall of the rain gutter 8. This is naturally the case even when cover 3 is lowered (FIG. 3) or is entirely or partly slid underneath the fixed top element 1 (FIG. 6). In each case the spring 6 acts so as to press the pivotable capping 4 against the wall of the rain gutter 8, whereby rattling noises are avoided.
The pivoting of cover 3 upward and downward, and the retracting thereof underneath the fixed top element 1 can be carried out by known means in a manner as is evident from an examination of FIGS. 1, 2, and 3 of the drawings.
It should be understood, of course, that the foregoing disclosure describes only a preferred embodiment of the invention and that is it intended to cover all changes and modifications of this example of the invention which fall in the scope of the appended claims.
