Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention comprises a cover provided in connection with a roof opening, and a blind web provided below the cover and capable of being automatically wound on a winding spool. The present invention relates to a blind for a vehicle roof in which a winding spool is rotatably attached to a holding means on a roof side.

[0002]

2. Description of the Related Art Such a known shade which can be wound on a take-up spool in a blind form (DE 195 38 552 C1) is intended to prevent the closed blind from loosening. In addition, a central support may be provided, but no measures are taken to tension the blind web laterally with respect to the pinch between its front end and its winding spool. In a similar known blind device (DE 44 24 188 c1), a blind stretched in the longitudinal direction is reinforced by a support frame. Because of this, the blind is divided into two tensioned longitudinal regions, so that the freedom of head movement in the interior space of the vehicle is not significantly impaired by the blind. Even in this case, the blind web is tensioned only in the direction of movement, and not in the direction transverse to the direction of movement.

[0003] In practice, such blinds are usually housed along a bar and are only tensioned between the front end of the blind and the take-up spool. This ensures that even when the blind web is nervous in this direction,
The lateral areas of the blind web tend to flutter during running wind, for example in a breathable blind web closing a roof opening.

[0004] Insect blinds of different genres, here door openings or window openings of a building (DE 196 394)
78 A1) has a side guide for insect repellent fabric. These side guides are formed by a mesh opening (Maschenoe) at the side edges of the repellent fabric formed from bristle or brush elements.
ffnungen) and elastically deformable support elements (Rueckha
lteelement). Such a device cannot be used as a blind in a vehicle roof. This is because the support elements cannot sufficiently prevent the blinds from coming off the side guides when dynamic wind acts on the blinds during the driving maneuver, and furthermore, the blinds always have a mesh opening. This is because it does not have a part.

It is an object of the present invention to provide a blind for a vehicle roof in which the side areas of the blind web do not flutter.

[0006]

The object of the present invention is to provide a blind web in which two opposite side edges are movably guided in guide rails in the direction of movement of the blind.
Being mounted transversely to the direction of movement of the blind so as not to disengage from the guide rail, the guide rail having a guide groove with a guide area bent relative to the plane of the blind web, and the blind The web has, at its opposite side edges, a plurality of reinforcing edges, which can be bent relative to the plane of the blind web for engagement with the bent guide area. However, in order to wind up the blind web on the take-up spool, the problem is solved by being able to return to a stretched, unfolded flat state.

[0007] Other advantageous or suitable configurations result from the dependent claims. These configurations are described below.

In accordance with the invention, the opposite side edges of the blind are guided in a guide rail according to the invention, while at the same time pressing laterally to the direction of movement of the blind so that the side edge does not deviate laterally from the guide rail. By means of (Festlegung), the lateral areas of the blind web are very effectively prevented from flapping the web. In this case, the easy and effective possibility of laterally pressing the side edge of the blind web while the side edge moves lightly in the guide rail is particularly effective when the guide groove is provided in the guide rail for the side edge of the blind web. Given by forming. The guide groove has a guide area which is bent with respect to the plane of the blind web, the side edge of the blind web provided with a reinforcing edge engaging in this guide area. These reinforcing edges are bendable with respect to the main plane of the blind web, but can be returned to their unstretched, unstretched state upon winding of the blind web. Therefore, the blind web can be wound onto the winding spool without bending the side edge. The bent side edge is laterally pressed by the bent guide region of the guide groove, and the movement of the side edge in the guide groove is maintained.

When the guide rails have such a spacing that the blind web is also tensioned in the lateral direction, as defined in claim 2, the blind web is tensioned, so to speak, in two axes, and thus the covering of the vehicle roof. When open, it can withstand the wind while traveling without fluttering and shaking.

[0010] The guide groove in the guide rail has a substantially inverted L-shaped cross section as described in claim 3, and the horizontal long side of the L is substantially in the plane of the blind web, but is directed downward. Advantageously, the short side is a guiding area for the side edge of the blind web. When the bent guide area is aligned substantially perpendicular to the plane of the blind web, the associated side edges of the blind web are bent substantially at right angles in the guide rails as claimed in claim 4. It is securely pressed in the lateral direction with respect to the moving direction of the blind so that the side edge does not come off.

According to the proposal of claim 5, the blind is actuated on both sides by pulling rolls or the like which are stored inconspicuously in guide rails. For storage, the guide groove may have a receiving passage for a pull roll or the like below the bent guide area.

In order to prevent the side edge of the blind web from constantly entering the guide rail when closing the wound blind, the side edge of the blind web according to claim 7 is used. It is an advantage that the front ends always remain on the guide rails, i.e. at these front ends, remain bent against the plane of the blind web.

The bending of the side edge before the side edge is introduced into the guide groove of the guide rail is facilitated by the installation of the guide element according to claim 8. These guiding elements, at one end, accommodate the side edges of the blind web in a flat condition and, at the other end, bend them forward along the corresponding guide grooves in the guide rails, with the side edges folded. . For this purpose, the guiding element has, as claimed in claim 9, each guide passage opening towards the blind web, which guide passage is in a partial area, i.e. on the side of the blind web. In the guiding area for the rims, these side edges are always and gradually bent to the desired state during the passage through the guide element, since they are provided spatially without transition steps.

[0014]

FIG. 1 shows a fixed roof surface 1 of a vehicle roof, a reinforcing frame 3 surrounding a roof opening 2 formed in the fixed roof surface 1, and FIG.
Now, a cover 4 provided in connection with the roof opening 2,
The sealing member 5 for sealing the gap at the edge of the cover 4 is shown by a dashed line. In the illustrated embodiment, the cover 4 is a glass cover, but may be formed as a thin plate cover. The cover 4 is provided movably with respect to the roof opening 2 as is well known. This need not be detailed here. This is because such an arrangement does not belong to the present invention. 1 and 2 show one side of the roof device and the blinds. The opposite sides are designed in a mirror image, and both sides are arranged parallel to one another in the area of the blind, which is relevant here. A roof frame 6 is fixed to the reinforcing frame 3, and this frame 6 is formed of, for example, an extruded aluminum profile. Cover 4
Below, a blind, generally designated by the reference numeral 7, is provided. The web 8 of the blind 7 can be wound on a winding spool 9. In order to rotatably hold the take-up spool 9, a holding thin plate 10 fixed to the roof frame 6 is provided, and the holding thin plate 10 has a pedestal 11 erected upward. Pedestal 1
The support shaft 12 of the take-up spool 9 is rotatably supported in one hole. The take-up spool 9 has a hollow cylindrical take-up body 13 which is provided coaxially with the support shaft 12 and surrounds a return spring 14 formed as a coil spring. Although the illustrated end of the return spring 14 is eccentrically provided on the take-up spool 9, the other end (not shown) of the return spring 14 is fixed outside the take-up spool 9,
When unwinding the blind web 8 from the take-up spool 9, the return spring 14 is tensioned. When the tensile force acting on the blind web 8 and extending the blind web 8 is reduced and becomes smaller than the stored spring force, the blind web 8 is automatically taken up by the take-up spool 9.

The blind web 8 is made of, for example, a breathable woven material or a woven material that can be formed more or less translucent depending on the desired degree of light shielding. The two opposing side edges of the blind web 8 are guided in the guide rail 15 so as to be movable in the direction of movement of the blind, but are mounted so as not to come off from the guide rail 15 in a direction transverse to the direction of movement of the blind. Have been. In this case, a pair of guide rails 1 facing each other
5 are spaced apart from each other by a distance which allows the blind web 8 movably guided by the guide rail 15 to be tensioned also in the lateral direction.

In the embodiment shown, the guide rail 15 is an integral component of the roof frame 6,
It can be formed during the extrusion of the profiled material for the roof frame 6. The guide rail 15 has a guide groove for a side edge of the blind web 8. These guide grooves have an upper passage 16 which lies in the plane of the blind web 8. In the passage 16 there is a downwardly directed bent guide area 1 for accommodating the corresponding side edge of the blind web 8.
7 is connected. In particular, as FIG. 2 clearly shows,
In the present embodiment, a downwardly bent guide region 17 extends substantially perpendicular to the plane of the blind web 8.

In order to engage the side edge of the blind web 8 with the guide rail 15, a reinforcing edge 18 having the same width is formed on the side edge of the web 8. These reinforcing edges 18 are bendable with respect to the plane of the blind web 8 for engagement with the bent guide area 17,
On the other hand, in order to wind up the blind web 8 on the winding spool 9, it is possible to return to the stretched, unfolded flat state as shown in FIG. The reinforcing edge 18 of the blind web 8 may be formed as a U-shaped sprayed or coated synthetic resin edge, as shown in exaggerated thickness in FIG. When using a suitable fiber material for the blind web 8 and / or a suitable synthetic resin, it is sufficient if the side edges of the blind web 8 are impregnated with a synthetic resin. In any case, reinforcement edge 1
Reference numeral 8 denotes a take-up spool 9 and a take-up spool 9
Can be easily turned in the direction of movement of the blind 7 and, when viewed from the lateral direction, at the transition between the edge piece and the free blind web 8, It is designed to bend more easily than bent inside the edge piece in the direction.

At the front end of the blind web 8, a horizontal bar 19 is provided.
However, it is usually provided as a tube formed from the material of the blind web 8. By applying force to the horizontal bar 19 in a direction away from the winding spool 9,
The blinds are unwound from the take-up spool 9, whereby stresses are obtained in the direction of movement of the blinds and at the same time laterally by the above arrangement and formation of the guide rails 15. Such a force input can be made manually. Further, a plurality of not-shown locking means for locking the horizontal bar 19 to adjust the position of the blind at the intermediate position are provided. However, it is preferable that a pull rope 20 or the like engaging with the front end of the blind 8 or the end of the cross bar 19 is provided in the guide rail 15 for operating the blind. Each pulling rope 20 may be formed, for example, as a Bowden wire, but a helical cable (Gewindekabel) normally provided for the operation of the sliding roof, ie a helical winding meshing with a pinion driven by a handwheel or an electric motor. It may be a helical cable with a take-up means (Gewindewicklung).

As can be seen for example from FIGS. 1 and 2, the guide groove has a receiving passage 21 below the bent guide area 17 in order to provide a pull rope 20 or the like.
The pulling rope 20 is immovably connected to the end of the cross bar 19 via the entraining means 22.

The arrangement is such that as long as the front end of the side edge having the reinforcing edge 18 of the blind web 8 always stays in the guide rail 15 or the guide groove of the guide rail 15, the winding web 8 The spool 9 can be wound up. 6 and 7 show a modification of the above embodiment. As shown in the drawing, a guide element 23 is attached to the rear end (roof side) of the guide rail 15 between the guide rail 15 and the take-up spool 9. Advantageously, the guide element 23 is attached to the roof frame 6. The guide element 23 is provided on the side of the blind web 8 having the reinforcing
And is guided into the guide groove of the guide rail 15. For this purpose, the guide element 23 has a guide passage 24 which opens towards the blind web 8. This guide channel 24 is provided in a spatially deflected manner in the direction of movement of the blind, together with a guide area 25 for the side edge of the web 8 having the reinforcing edge 18. The guide area 25 is provided for the winding spool 9 of the guiding element 23.
At the end on the side, it lies approximately in the plane of the blind web 8, but at the end on the guide rail 15 side of the guide element 23 is connected in line with the corresponding guide area 17 of the guide groove of the adjacent guide rail 15. It is bent like so. The spatially diverted guide passage 24 is used to extend the blind web 8 during the feeding process from an extended flat state as shown on the right side of FIG. 7 to a state of being bent at a right angle as shown on the left side of FIG. The side edge with the reinforcing edge 18 is turned.
On the other hand, during the winding process, the guide path 2 which is spatially turned
4 returns the reinforcing side piece of the web 8 bent at a right angle to a flat state that can be wound up.

As described above, in the present embodiment, the cover 4 movably provided in relation to the roof opening 2.
Below, there is proposed a blind for a vehicle roof that is automatically wound up on a winding spool held on the roof side when not in use. The side edges of the blind web are movably guided along guide rails mounted laterally at the roof opening. During the opening and closing movements of the blind, the side edges of the web move lightly within the guide rails 15 and the guide rails do not come off from the guide rails 15 in a direction transverse to the direction of movement of the blinds. And the side edges of the blind web engage each other. Therefore, the edge area of the blind does not flutter or shake.
