Closed in.

Rails 54 extending in parallel with each other through the opposite opening edges of the window opening 52 are provided, and the rail 54 includes a main rail 55 located at the opening edge and a sub-rail located at a position deviating from the opening edge. It consists of 56 and. Then, each end of the sunshade 57 is slidably fitted over the main rail 55 and the sub-rail 56, and the window opening 52 is opened and closed by the sliding of the sunshade 57. Through it, it is possible to select lighting or shading.

Further, in the above case, the main rail 55 and the sub rail 56 are individually attached to the roof panel 51 side, and a gap 1 is formed between the opposite ends of these rails 55, 56.

(Problems to be solved by the invention) Therefore, in the above conventional configuration, the main rail 55 and the sub rail 56
Since they are individually attached, a relatively large assembly error may occur between the opposite ends of the two, and in this case, a step is generated between the opposite ends, and as a result, the rail 54 is There is an inconvenience that smooth sliding of the sun shade 57 is hindered.

Therefore, by connecting the opposite ends to each other, both rails 55, 5
It is conceivable to prevent a step from occurring between the opposite ends of 6. However, in this case, this connection may complicate the configuration of the rail 54.

(Purpose of the Invention) The present invention was made by paying attention to the above circumstances, and by connecting the opposite ends of the main rail and the sub-rail, a step is not generated between the opposite ends. And then
It is an object to ensure a smooth sliding of the sunshade with respect to the rail, and yet to achieve this with a simple construction.

(Structure of the Invention) The feature of the present invention for achieving the above-mentioned object is that, of the opposite ends of the main rail and the sub-rail, the fitting groove into which the outer flange of the opposite end of one rail is fitted is the other. The outer flange can be fitted into the fitting groove by elastically deforming the opposite end of one of the rails, and the fitting ends connect the opposite ends to each other.

(Operation) The operation of the above configuration is as follows.

Since the opposite ends of the main rail 25 and the auxiliary rail 26 are connected to each other, it is possible to prevent a step from being formed between the opposite ends of the main rail 25 and the auxiliary rail 26 as compared with the case where they are individually attached. .

Further, the connection between the opposite ends is performed by utilizing the outer flange 42 formed on the sub rail (one rail) 26 of the main rail 25 and the sub rail 26, and connecting this to the main rail (the other rail) 25. First fitting groove (fitting groove) 47 formed at the opposite end of
Since it is achieved by fitting the sub rail (one rail) 26, the constituent portion of the sub rail (one rail) 26 is effectively used.

In addition, since the outer flange 42 can be fitted into the first fitting groove (fitting groove) 47 by elastically deforming the opposite ends of the sub rail (one rail) 26, both of them can be fitted after the fitting. The connected state of the opposite ends is held by the elastic force of the sub rail (one rail) 26. That is, the elasticity of the sub rail (one rail) 26 is effectively used.

Reference numeral 31 is a sunshade, and the front and rear ends of the sunshade 31 are slidably fitted into the corresponding rails 23, whereby the sunshade 31 is guided by the rails 23 and is movable in the vehicle width direction. By this movement, if the sunshade 31 is located on the main rail 25 side, the ceiling opening 15 is closed and light is shielded, while if it is moved to the subrail 26 side, the sunshade 31 is stored. That is, in this case, the ceiling opening 15 is opened to enable daylighting.

In particular, referring to FIGS. 1 and 7, the sun shade 31 will be described in more detail.

The sunshade 31 has flexibility and is composed of an upper sheet 32, an intermediate sheet 33, and a lower sheet 34, which are stacked one above the other, and these are bonded to each other with an adhesive. The upper sheet 32 serves as a base material of the sunshade 31, and has a cross-sectional corrugated shape having convex portions 32a and concave portions 32b alternately at equal pitches, and these convex portions 32a and concave portions 32b extend in the front-rear direction. ing. Further, the material of the upper sheet 32 has a multiple structure in which a nonwoven fabric and paper are alternately laminated on top and bottom.

On the other hand, the intermediate sheet 33 is a water resistant paper, which prevents rainwater from passing through the sunshade 31 and reaching the passenger compartment 11. Also, the lower sheet 34 is a non-woven fabric, which improves the appearance of the sunshade 31 from the passenger compartment 11.

As shown in FIG. 4, sliders 35 are provided at the respective corners of the sunshade 31 so that the sunshade 31 can slide on the rail 23 without rattling. That is, the slider 35 slides while being pressed against the inner surface of the groove 24 of the rail 23 by the elastic force. In addition, 36 is a handle.

In FIGS. 3 to 6, the sunshade 31 has flexibility as described above. However, due to this, the front and rear midway portions are bent due to their own weight. Then, if this deflection is large, this sunshade 31 may have an unpleasant appearance, and the front and rear midway portions thereof may contact the ceiling frame 19 and the opening trim 20 to hinder the movement of the sunshade 31. .

Therefore, between the rails 23, 23, a pair of front and rear resin bearings 37,
37 are provided, and each of the bearings 37 slides on the lower surface of the sunshade 31 to support the sunshade 31. In this case, each bearing 37 is screwed onto the ceiling frame 19 by bolts 38. It should be noted that these support bodies 37, 37 are provided at positions where the movement trajectory of the handle 36 is bent from the front and rear so that the support bodies 37, 37 and the front and rear handles 36 do not interfere with each other.

On the other hand, an opening trim 40 that borders the window opening 14 is provided. Each of the opening trim 40 front and rear trim
40a is integrally formed on the upper surface of each main rail 25.
The inner trim 40b of the opening trim 40 on the inner end side in the vehicle width direction detachably connects the inner ends of the front and rear trims 40a, 40a. Also, the outer trim 40
As for c, the outer ends of the front and rear trims 40a, 40a are detachably connected to each other, and the outer trim 40c is made of sheet metal and integrally formed with the connecting bar 28.

Next, the connecting portion between the main rail 25 and the sub rail 26 will be described in detail with reference to FIG. 1 and FIGS. 7 to 9.

One of the main rail 25 and the sub-rail 26, which is one of the sub-rails, is made of elastic metal plate as described above, and outer flanges 42, 42 are integrally formed at the opening edge in the cross section thereof. Further, an end flange 43 is integrally formed at the opposite end of the sub rail 26 facing the main rail 25, and the outer flange 42 and the end flange 43 serve as a reinforcing material for the sub rail 26.

On the other hand, in the main rail 25, which is the other rail,
An upper connecting piece 44 and a lower connecting piece 45, which project toward the sub rail 26, are integrally formed at the end opposite to 26. The first fitting groove 4 into which the outer flange 42, 42 is fitted is formed at the end edge on the sunshade 31 side of each of the facing surfaces of the both pieces 44, 45.
7 are formed respectively. Further, second fitting grooves 48 into which the end flanges 43 are fitted are formed respectively on the base sides of the facing surfaces of the two pieces 44, 45, respectively. The upper connecting piece 44 is also integrated with the opening trim 40, and therefore the upper connecting piece 44 has particularly sufficient strength.

Then, fitting the outer flange 42 into the first fitting groove 47,
By fitting the end flange 43 into the second fitting groove 48, the opposite ends of the main rail 25 and the auxiliary rail 26 are connected to each other, and at this time, the concave groove 24a in the main rail 25 and the concave groove 24b in the auxiliary rail 26 are connected. And are connected smoothly so that there is no step at the connecting part.

Further, in the above case, the upper connecting piece 44 and the lower connecting piece 45 have inclined surfaces 44a, 45a on their respective opposing surfaces, and both inclined surfaces 44a, 4a.
5a is inclined so that the size of both gaps increases in the front-rear direction as the distance from the sunshade 31 increases.

When connecting the opposite ends of the main rail 25 and the sub-rail 26 as described above, first, as shown by the phantom line in FIG. The opposite end of the sub rail 26 is located at a position away from the end rail 43, and the end flange 43 and the second fitting groove 48 are opposed to each other in the front-rear direction. Next, as shown by an arrow A in the figure, the opposite end of the sub rail 26 is pushed between the upper connecting piece 44 and the lower connecting piece 45. Then, as the pushing progresses, the outer flanges 42, 42 are compressed so as to come closer to each other while slidingly contacting the inclined surfaces 44a, 45a. That is, this causes the opposite ends of the sub rails 26 to elastically deform so as to contract vertically. And after this,
If each outer flange 42 is fitted into the first fitting groove 47, the sub rail
The opposing ends of 26 are almost restored by the elastic force, that is, the fitted state is held by the elastic force of the sub rail 26. Further, at this time, the end flange 43 also has the second fitting groove.
The main rail 25 and the sub-rail 26 are connected to each other at their opposite ends.

(Effect of the Invention) According to this invention, since the opposite ends of the main rail and the auxiliary rail are connected to each other, a step is formed between the opposite ends of the main rail and the auxiliary rail, as compared with the case where the main rail and the auxiliary rail are individually attached. Is prevented from occurring. Therefore, smooth sliding of the sunshade with respect to the rail is ensured.

Further, the connection between the opposite ends is carried out by using an outer flange formed on one rail of the main rail and the sub-rail and fitting it into a fitting groove formed at the opposite end of the other rail. Since it is achieved by doing so, the constituent part of one rail is effectively used, and thus the connection between the opposite ends is achieved by a simple structure.

Moreover, since the outer flange can be fitted into the fitting groove by elastically deforming the opposite ends of the one rail, the connection state of both the opposite ends after the fitting is the elasticity of the one rail. It will be held by force. That is, since the elasticity of one rail is effectively used, the connection between the opposite ends can be achieved with a simple structure in this respect as well.
