Background of the Invention
The invention relates to a sliding roof assembly for vehicles and method of mounting same.
It is to be understood that throughout the following specification such terms as "upper", "lower", "vertical", "horizontal", "front" and "rear" are employed only for convenience of identification of the sliding roof assembly relative to its normal position of use on a vehicle.
Until now a specialized workshop has been needed for the purpose of subsequently providing a motor vehicle with a sliding roof which had initially been constructed without such a roof in the manufacturer's works. The fitting of a sliding roof into a motor vehicle commonly requires operations of such complex nature that such operations can only be undertaken by personnel specializing in this work.
In a known process for the production of a sliding roof in a motor vehicle, a substantially rectangular opening of the size of the sliding roof member is initially formed in the vehicle roof and a frame for the sliding roof member which closes off the excised opening in the closed position is then mounted on the vehicle roof from below, for which purpose the rim of the vehicle roof surrounding the roof opening is swaged over around a horizontal upper flange of the frame. The sliding roof member is then inserted into the frame and the whole is precisely adjusted. The entire vehicle roof must thereafter be rubbed down and resprayed.
Summary of the Invention
The object of the present invention is to provide a sliding roof assembly for vehicles such that its installation in a vehicle may easily be performed even by untrained or semi-skilled personnel.
The present invention consists in a sliding roof assembly for vehicles comprising a frame, a roof member slidably mounted in said frame and a covering panel mounted on said frame and provided with a substantially rectangular aperture in its front portion of substantially the same size as the roof member and a rear portion which covers the roof member when the latter is moved rearwardly to uncover said aperture, said panel being provided with a peripheral supporting rim which projects outwardly from the frame and which is adapted to rest on the vehicle roof.
The invention also consists in a method of mounting a sliding roof assembly as referred to above in a motor vehicle comprising the steps of forming an aperture in the vehicle roof of substantially the same dimensions as the frame, inserting into the aperture from above the sliding roof assembly in such manner that the supporting rim of the covering panel rests on said vehicle roof around the aperture and then connecting the covering panel to the vehicle roof.
The assembly comprising the frame, the sliding roof member and the covering panel is preferably assembled at the works and, in doing so, the sliding roof member is precisely adjusted in position within the frame. The operations remaining to be performed for installing this assembly in a vehicle are so simple that they may also be undertaken without any difficulty by untrained personnel. The fitting of the assembly as a unit into the vehicle roof from above through the aperture does not raise any technical difficulties, whilst any damage to the vehicle roof along the edge of the aperture is covered by means of the supporting rim of the covering panel, so that a respraying operation on the vehicle roof is no longer necessary.

Description of a Preferred Embodiment
In order to provide a vehicle with a sliding roof, use is made of a structure 1, already assembled at the works, comprising a sliding roof 3 which is assembled and slidably mounted in a frame 2, the latter having a covering panel 4 mounted thereon. The covering panel 4 has a rectangular aperture 5 in its front portion of a size corresponding to the dimensions of the sliding roof 3, so that the aperture is closable by the sliding roof 3. The covering panel 4 is connected to the frame 2 by swaging its rim surrounding the aperture 5 around the horizontal top flange 2' of the frame 2.
To the rear of the aperture 5, the panel 4 has a portion 6 under which the sliding roof 3 is postioned when it is moved rearwardly to uncover the aperture 5. The panel 4 has a peripheral supporting rim 7 extending around the frame 2 which projects outwardly from same. This supporting rim 7 is provided with fastening bolts 8 which extend downwardly at right angles and are evenly spaced around the entire supporting rim. Carrying arms or brackets 9 are fastened on the outer surface of a vertical portion 2" of the frame 2 and/or on the underside of the supporting rim 7 of the panel 4, each of the brackets having an opening through which a bolt 8 extends, the bolt head 8' being positioned within a gap formed between the carrying bracket 9 and the supporting rim 7. Each bolt is non-rotatably connected to the carrying bracket 9.
On the underside of an inwardly extending and generally horizontal bottom flange 2'" of the frame 2 is positioned a lining 10 with a resilient packing 11 positioned between the bottom flange 2'" and the lining 10. The bottom flange 2'" of the frame 2 is bent upwardly at right angles adjacent its inner edge and then inwardly at right angles to form a step, as apparent from FIGS. 2 and 4. The lining 10 has its outer edge glued to the vertical frame portion 2" of the frame 2, whilst its inner edge is glued on the upper side of the inwardly extending extremity of the bottom flange 2'". The lining 10 may be of a different colour from that of the roof lining 12, i.e. perferably in a shade providing a strong contrast with the colour of the roof lining 12.
Prior to installing this sliding roof assembly 1 into a motor vehicle, a rectangular aperture 14 is formed in the roof 13 of the motor vehicle. This aperture 14 is so dimensioned that the frame 2 and associated sliding roof 3 can be inserted from above into the aperture 14 with the supporting rim 7 of the covering panel 4 resting on the vehicle roof 13 around the periphery of the aperture 14.
Holes 15 through which the fastening bolts 8 are passed upon insertion of the sliding roof assembly 1 are drilled in the vehicle roof 13 around the aperture 14. The aperture 14, together with the holes 15, are preferably traced on to the vehicle roof 13 by means of a templet, so that the neat and precise excision of the aperture 14, as well as the required spacing of the holes 15 is ensured.
After the aperture 14 has been formed in the vehicle roof 13, an at least approximately rectangular opening 16 is cut from the roof lining 12, the longitudinal and transverse dimensions of which are somewhat smaller than the corresponding dimensions of the aperture 14, as will be apparent from FIG. 2.
A web of a reinforcing section 17 bears against the underside of the vehicle roof 13 and has an opening therethrough for the passage of a bolt 8, on to which is then fixed from below a nut 19. The reinforcing section 17 is of U-shaped cross-section and in the form of a rectangular frame appropriate to the size of the aperture 14.
Brackets 18 are suspended from at least some of the bolts 8, below the reinforcing section 17. Each bracket 18 has a horizontal upper flange with an aperture therethrough for the passage of a bolt 8. Nuts 19 are then screwed on to the bolts 8, as shown in FIG. 4.
After the fastening of the assembly 1 on the vehicle roof 13 has been completed, the inner edge of the roof lining 12 bordering its opening 16 is glued around the opening onto the underside of the lining 10 on the bottom flange 2'" of the frame 2.
The joint between the roof lining 12 and the lining 10 is then covered from below by a covering strip 20. To effect this, the horizontal bottom flanges of the brackets 18 are provided with openings 21 into which snap-in elements 22 mounted on the covering strip 20 are engaged by pressure from below. The covering strip 20 has a lining 23, preferably of the same colour as the lining 10, so that these two linings are colour-matched but contrast with the remainder of the roof lining. To simplify the assembly, the covering strip 20 is also in the form of a rectangular frame, so that it may be secured as a unit in an easy and convenient manner from below by means of the snap-in elements 22.
As shown by FIGS. 2 and 4, the supporting rim 7 of the panel 4 has a greater curvature, in cross-section, than the vehicle roof 13 at this point, the gap between these two being filled by a filler member 24 comprising a material which deforms uniformly under pressure, so that the member 24 moulds itself to the shape of the vehicle roof 13 upon the nuts 19 being tightened for the purpose of connecting the panel 4 to the vehicle roof 13. The member 24 is also sealed with respect to the vehicle roof 13 by means of a suitable sealer "putty". The member 24 also has passages for the bolts 8.
To render unnecessary the respraying of the vehicle roof 13 after the fitting operation, the panel 4 and the upper surface of the sliding roof 3 are sprayed in a shade which differs from, and preferably contrasts, with the vehicle roof 13.
The mounting of the panel 4 on the roof 13 of the vehicle may be effected by spot welding or rivetting, instead of the fastening bolts 8 referred to.
The present invention offers, for the first time, the possibility of equipping vehicles with sliding roofs, without having to find a specialist business for this purpose. Thus, it is possible for any workmanlike amateur to provide his vehicle with a perfectly functioning sliding roof.
The invention is not limited to the example of embodiment shown in the drawings, but may be modified in various ways within the scope of the appended claims.
