Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding roof that is fitted into an opening in a vehicle roof so as to be openable and closable and functions movably as a part of the vehicle roof, such as a so-called "sunroof" in an automobile. This invention relates to an improvement in the airtight and watertight waterproof structure between the roof and the opening.

2. Description of the Related Art A device that provides an opening above a driver's cab in the roof of a vehicle such as a passenger car and covers the opening with a lid that can be opened and closed is well known as a so-called "sunroof" device. However, since this lid that can be opened and closed is a movable roof that functions as a part of the vehicle roof, it has a sufficiently waterproof structure when closed.
It is necessary to effectively play the role of defense against the wind and rain of the outside world. However, this type of conventional sunroof device has the following problems in its waterproof structure between the lid, that is, the sliding roof, and the opening.

That is, FIG. 1 shows an example of the main parts of a conventional waterproof structure, where R is the roof of the vehicle and SR is a sliding roof.
is fitted into an opening W in the roof R so as to be openable and closable, and as shown in the figure, a seal with a roughly U-shaped cross section made of rubber or other watertight material is installed around the periphery of the sliding roof SR. A structure in which the member Sl is attached and the sealing member Sl closely closes and closes the inner wall F forming the periphery of the opening W and extending in the vertical direction on the roof R side in a line contact state is usual. In addition, when opening and closing this type of sliding roof, it is customary to take a tilted position and then slide it linearly. Therefore, in the above seal structure, the manufacturing dimensional tolerance of the sliding roof SR, the seal member Sl Unless all of the manufacturing dimensional tolerances of the roof R and the manufacturing dimensional tolerances of the roof R are within extremely strict ranges,
It is easy to cause problems such as water leakage and outside air intrusion accidents, or conversely, the gap becomes too small and the sliding roof becomes difficult to tighten.
Furthermore, if the gap becomes too small, there is a problem that the sealing member may come off.

The present invention solves the above-mentioned problems by forming a vertical mating surface on the periphery of the sliding roof and the opening without interfering with the opening/closing movement of the sliding roof, and forming a vertical mating surface between the mating surfaces. The sealing member can be filled in a hermetically sealed manner, improving sealing performance and eliminating conventional problems.
Therefore, the feature is that the sliding roof fits into the opening of the vehicle roof from below to close the opening, and the rear part of the sliding roof descends from the closed state, and A waterproof structure between the sliding roof and the opening of a sunroof device configured such that the entire sliding roof moves rearward to open the opening, the sliding roof comprising:
Among the peripheral edges, at least the left and right sides and rear side peripheral edges are shaped to fit below the peripheral edge of the opening in a mating shape, and correspond to the upper peripheral surface of the sliding roof and the peripheral upper surface that are inserted in the mating shape. A sealing member is interposed between the lower surface of the periphery of the opening.

The embodiments shown in the drawings will be described in detail below. FIG. 2 shows an example of a vehicle roof implementing the present invention and a sliding roof installed on the same roof, and FIG. The figure shows a side sectional view of each main part structure taken along the line B-B in the same figure, Figure 5 shows the line C-C in the same figure, Figure 6 shows a side sectional view of the structure of each main part taken along the line D-D in the same figure, and Figure 7 shows the sliding roof in the same figure. In Fig. 2, 6 indicates the roof of the vehicle body (body roof) of a passenger car, etc. The left side of the figure is the front side, and the right side is the rear side. As shown in the figure, an opening 6a is formed in the roof 6 near the front, and a sliding roof 101 is fitted into the opening 6a so as to be tiltable and slidable as described later. This is a sealing member such as a weather strip according to the invention.
The details of the waterproof structure using the sealing member 10 of the present invention will be explained below.
01 and the opening 6a, detailed explanations of conventionally known structures and parts will be omitted, and only the main structure of the present invention will be described.

3 to 6, the sliding roof 101 is composed of a top plate 1, a middle plate 2, a bottom plate 3, which are superimposed and fixed together, and a ceiling plate 11 which is connected and held to the bottom plate 3. 1 and the middle plate 2 have bent edges 1a and 2a that stop inside the opening 6a, and the bottom plate 3 has bent edges 1a and 2a that extend below the periphery 6b of the roof 6, which is the periphery of the opening 6a. forming an extended peripheral edge 3a located parallel to the peripheral edge 6b;
Using rubber or other water-tight and elastic material between the mating surfaces of the peripheral edge 6b and the extended peripheral edge 3b, a bottom part fixed to the extended peripheral edge 3a side, and a top part that tightly contacts the back surface of the peripheral edge 6b; Furthermore, the bent edge 1a,
A thick strip-shaped sealing member 10 is inserted, which is in close contact with the outer surface of the seal member 2a and has a side portion that fills the gap between the bent edges 1a, 2a and the end surface of the peripheral edge 6b. hollow part,
15 indicates a caulking material. In this case, the seal member 10 is provided over the entire periphery (front, rear, and both sides) of the sliding roof 101. In FIG. 3, reference numeral 9 denotes a stopper attached to the tip of the extended peripheral edge 3a on the front side, and the stopper 9 is made of the same material as the sealing member 10 and comes into elastic contact with the step 7a of the fixing plate 7 provided on the inner surface of the roof 6. Ru. In FIG. 3, 4 and 5 indicate fasteners such as bolts and nuts, 8 is a mounting frame attached to the fixing plate 7, and 12 is a well-known opening 6a.
This is a wind deflector that is located on the front side of the vehicle and located at the lower front side of the sliding roof 101. This is a wind deflector that is located at the front side of the vehicle and located at the lower part of the front side of the sliding roof 101. This is to prevent noise caused by wind entering. Further, 14 is a head lining integrated with the vehicle body roof 6 side, and 13 is a seaming welt attached to the periphery of both ends of the mounting frame 8 and the head lining 14, both of which have known structures.

FIG. 3 shows a state in which the sliding roof 101 closes the opening 6a, but when opening the sliding roof 101, the roof 101 uses the pivot point as a fulcrum to open the sliding roof 101, which will be described later. The entire body is inclined backward so that the front end thereof does not protrude upwardly above the upper surface of the vehicle body roof 6, and the rear end, which is the lowest end of the inclination, is between the vehicle body roof 6 and the head lining 14. It slides linearly into the space to open the opening 6a. When the sliding roof 101 is tilted backward, in the conventional sunroof device, the front edge of the sliding roof moves upward, but in this embodiment, the front edge of the sliding roof moves upward.
Since the extended peripheral edge 3a of the front end of the sliding roof 101 extends below the opening peripheral edge 6b, it cannot move upward. Therefore, in this embodiment, a slide guide mechanism is provided so that the sliding roof 101 can be tilted backwards as shown in FIG. That is, as is clear from the cross-sectional views in FIGS. 4 and 5, on the side extending into the opening 6a of the mounting frame 8 on the vehicle roof 6 side, there is a lower guide rail on the front side in FIG. 27 is installed along the length of the sliding roof 101 together with the guide rail cover 28 through waterproof packing 30 and fasteners 31 and 32 such as bolts and nuts, and slides formed on both sides of the rail cover 28 in the width direction are provided. Slide shoes 2 at the lower ends of both sides of the front slide bracket 22 are inserted into the grooves.
9 and the tail portion 36a on which the cable 36 is inserted and supported are both slidably engaged, and furthermore, a front shaft 23 is inserted and supported in the upper part of the bracket 22, and the shaft 23 is connected to the sliding roof 10.
A snap ring 2 for preventing detachment is slidably inserted into a cam groove 52 of a front cam 21 supported by a front guide bracket 20 which is adjustable by adjustment bolts 33, 34 and 35 on the bottom plate 3 of the front cam 21.
6, and the side view of this series of front slide guide mechanisms is as shown in FIG.
Further, in FIG. 4, 16 is a fastener for attachment to the bottom plate 3 of the ceiling plate 11 mentioned above, 17 is leather (hardboard), 18 is an elastic material such as urethane,
Reference numeral 19 indicates a leather, and in FIG. 6, reference numeral 24 indicates a mounting screw for the front cam 20, and reference numeral 25 indicates a washer. As shown in the figure, the cam grooves 52 in the front cam 21 include a horizontal groove 52a at a lower level and parallel to the sliding direction, an upwardly inclined groove 52b following this, and a cam groove 52b that is higher than the horizontal groove 52a and parallel to the sliding direction. horizontal groove 52 parallel to
It is formed from c.

Furthermore, as for the slide guide mechanism on the rear side, as shown in FIGS. 5 and 6, the lower guide rail 27 and the upper guide rail 48 (following the guide rail cover 28) of the mounting frame 8 are the same, and both rails 27 , 48 in the slide grooves on both sides in the width direction are the combined rear slide brackets 46.
slide show 29 and slide holder 47
The tail portions 47a of the cables 36 are slidably engaged with each other, and a stopper 49 is provided on the upper guide rail 48, and a stopper 49 is provided at the front end of the stopper 49 on the rear guide bracket 38. The slide roller 45 is locked, and the rear guide bracket 38 is attached to the sliding roof 101.
The lift cam 37 is fixedly held on the bottom plate 3 by fasteners such as bolts 4 and nuts 5, and the lift cam 37 is fixed and held by fasteners such as screws 40 and nuts 50 on the front surface of the rear guide bracket 38 opposite to the mounting side of the slide roller 45. The rear shaft 42 is fixed to the cam groove 53 provided in the cam 37 with a detachment prevention ring 41.
The ceiling plate 1 on the side opposite to the lift cam 37 of the rear shaft 42 is slidably engaged at one end through the lift cam 37 of the rear shaft 42.
On the shaft extending to the first side, a roller 43 and a pushing roller 44 are arranged in a row as shown in the fifth figure. In FIG. 5, reference numeral 39 indicates a washer of the screw 40, and as shown in FIG. It consists of a diagonal groove 53b that rises upwardly, and 54 indicates each fixing device between the cable 36 and the slide holder 47 of the front slide bracket 22 and the rear slide bracket 46.

Describing the opening/closing operation of the sliding roof 101 having the above configuration, FIG. 6 shows the sliding roof 101 in a closed state, and from this state the cable 36 is moved backward (to the right in FIG. 6). If the front slide bracket 22 and the slide holder 47 of the rear slide bracket 46 move together, the front shaft 23 and the rear shaft 42 will also move rearward. Both shafts 23,
The front cam 21 and the lift cam 37, which are engaged with each other through the cam grooves 52 and 53, are both fixed to the sliding roof 101 side, so they cannot be moved until the slide roller 45 hits the stopper 49. do not have. That is, both cams 21, 3
7 do not move together, only the front shaft 23 and the rear shaft 42 are moved by the respective cams 21 and 37.
It moves backward according to the shape of the cam grooves 52 and 53, resulting in the state shown in Fig. 7,
In other words, the front end of the sliding roof 101 remains as it is, and the rear side is lowered to a backward tilted position. By moving the cable 36 further rearward from this tilted position, the sliding roof 101 is moved to the roof 6 of the vehicle body. and the head lining 14, and the opening 6a is opened.

The reason why the front end of the sliding roof 101 (on the stopper 9 side) does not rise upward is because of the grooves 52a and 52 of the cam groove 52 of the front cam 21 that the front shaft 23 engages and slides on.
This is due to a series of guide shapes 52b and 52c, which allows the position of the front end stopper 9 to be adjusted in any way. That is, although it is impossible for the stopper 9 to move upward, it is also undesirable for the stopper 9 to move too far downward. This is because, as is known, there is a wind deflector 12 near this area, so if it is lowered more than necessary, it will interfere with the sliding roof 101 when it slides, and the cam groove 52
By appropriately designing the groove shape of the sliding roof 101, in this embodiment, the rearward tilting position required for storage can be controlled as desired without causing the front end of the sliding roof 101 to protrude upward. At this time, the position of the stopper 9 does not rise on both sides in the width direction of the opening 6a.

The waterproof structure of the sliding roof 101 of this embodiment is as described above, and the roof 10
1 and the opening 6a, the opening periphery 6b and the extended periphery 3a of the sliding roof 101,
The top and bottom are parallel to each other, and the periphery 6
By interposing the sealing member 10 in a filling and sealing manner on the mating surfaces of b and 3a, an extremely wide sealing surface can be obtained under surface contact, and its watertight and airtight sealing performance is significantly improved compared to conventional ones. Furthermore, there is less risk of damage due to wear and tear, increasing the durability of the sealing member, and furthermore, the sealing function can be reliably and stably performed without detachment or deformation during sliding opening/closing operations. In addition, in the case of a seal structure on such a mating surface, which is difficult with the tilting position method of the conventional sliding roof, the cam groove shape of the front cam and rear cam allows the front end to be placed behind the roof without fear of rising. Since the tilting position can be smoothly obtained, this structure is excellent as a structure for preventing a sliding roof in this type of sunroof device.

It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, the structure in which the periphery of the sliding roof 101 fits below the periphery of the opening 6 can be applied to the entire periphery of the opening 6. It is not necessary to cover the entire area, and it may be sufficient to cover at least only the left and right sides and the rear side. The front periphery is the same as before.
It may be in contact with an inner wall extending in the vertical direction. In this case, when the sliding roof is tilted back, its leading edge may rise as before.

In this way, by making only three sides into the structure, there is no need for fitting precision compared to the conventional structure that fits into the inner wall of the opening.

According to the present invention, compared to the conventional structure in which the outer circumferential edge of the sliding roof is inscribed in the vertical inner wall of the periphery of the roof opening, the fitting precision of the sliding roof is not required, and therefore manufacturing becomes easier. Further, water leakage and outside air intrusion accidents due to manufacturing dimensional errors are prevented, and the sealing member does not come off.
