Description

[Detailed explanation of the idea] This invention relates to a drainage system for an automobile with a retractable roof.

Generally, in an automobile with a retractable roof, water accumulated in a drain groove formed in a sunroof frame is discharged to the outside of the vehicle through a drain pipe.

As shown in FIG. 1, one end of a conventional drain pipe 1 is connected to a drain groove 3 formed in a sunroof frame 2, and the other end is connected to a hole 5 formed in a rear floor 4a of a vehicle body 4 via a plug 6. It was set up so that

For this reason, the above-mentioned hole 5 is selectively formed only in the car body 4 having the sunroof frame 2, or alternatively, in order to avoid the former troublesome selection process, the hole 5 may be formed selectively in the car body 4 having the sunroof frame 2 but not having the sunroof frame 2. Regardless, it was formed on the body 4 of all automobiles.

As a result, in the former case, it is necessary to go through the process of selecting whether the car has a sunroof frame 2 or not, and then drill holes only in the car body that has a sunroof frame.
Moreover, in the latter case, since the vehicle body 4, which does not require a hole 5, is also perforated, there is a problem that a plug is required to prevent rainwater from entering the hole 5.

This idea was created in view of the above-mentioned conventional problems, and allows a drain pipe connected to the drain groove of the sunroof frame to be attached to the car body without drilling holes in the car body or using separate parts. The purpose of this invention is to obtain a drainage system for an automobile with a retractable roof.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 8 is a drainage groove formed in the sunroof frame 9, and 10 is a ventilation exhaust hole formed in the rear fender 12 of the automobile body 11. The air inside the vehicle compartment 13 is exhausted.

Reference numeral 14 denotes a draft turf racket fixed to the inner surface of the rear fender 12, and the drafter bracket 14 has a flange portion 15 around the flange portion 15 having a substantially U-shaped cross section that abuts against the inner surface of the rear fender 12, and a flange portion 15 in the center thereof. It has a recessed part 16 that is recessed inward, and the recessed part 16
A gap 17 whose upper end opens into the vehicle compartment 13 is formed between the rear fender 12 and the rear fender 12, and this gap 17 communicates with the ventilation exhaust hole 10.

Gap 17 in flange portion 15 of drafter bracket 14
The upper end of the opening where is formed is the ventilation exhaust hole 10.
It is located higher than the top position of.

Further, the drafter bracket 14 having the above-mentioned void 17 and the ventilation exhaust hole 10 collectively constitute a ventilation exhaust port 18.

Reference numeral 19 denotes a drain pipe, one end of which opens into the drain groove 8 via the drain pipe 20, the middle of which passes through the space between the inner and outer panels of the vehicle body 11, and the other end of which opens into the ventilation exhaust port 1B. It is inserted so that it opens.

Next, the effect will be explained.

Although a seal is provided between the sunroof panel (not shown) and the sunroof frame 9, rainwater still enters through a small gap and collects in the drain groove 8 formed in the sunroof frame 9.

Rainwater collected in the drain 8 flows into the drain 19 from one end of the drain 19 communicating with the drain 8 via the drain pipe 20.

Rainwater flowing into the drain pipe 19 flows through the drain pipe 19 and is discharged into the gap 17 from the other end of the drain pipe 19 located within the ventilation outlet 1B.

The rainwater discharged into this gap 17 is then drained into the ventilation exhaust hole 1
0 and is ejected from the vehicle.

As explained above, according to this invention, the structure is such that a drain pipe is provided with one end connected to the drain groove formed in the sunroof frame and the other end located at the ventilation exhaust port of the passenger compartment. Therefore, the selection process and drilling work when forming holes only in cars with a sunroof frame, the drilling work when forming holes in all cars, and the work to plug holes in cars without a sunroof frame. In addition to eliminating the need for the drain pipe, a bracket plate, grommet, etc. may be inserted between the other end of the drain pipe and the upper end of the drafter bracket in order to prevent the other end of the drain pipe from hanging in the air. There is no need to attach and fix the other end of the drain pipe, and the other end of the drain pipe can simply be inserted into the opening at the upper end of the drafter bracket and will be supported by the opening without being left hanging. can get.
