Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a drainage device for a sunroof installed in a vehicle such as an automobile.

(Prior Art) As a conventional sunroof, for example, a gutter portion corresponding to the entire periphery of the opening is provided below an opening in a vehicle roof that is opened and closed by a panel, and a pair of guide rails are installed in the left and right sides of this gutter portion. The front pivot parts of the lifters provided on both left and right sides of the panel are fitted to the guide rails so as to be rotatable and movable back and forth, and the sliders are fitted so that they are movable back and forth, forming cam grooves in the lifters. However, there is one in which the slider is provided with a roller that engages with the cam groove. Then, as the slider moves, the roller moves within the cam groove to raise and lower the rear part of the panel around the pivot portion, and when the roller is at the rear end of the cam groove, the panel is tilted backward upward. When the slider is moved backward in this state, the panel moves backward and opens the opening.

For drainage of the sunroof, a drainage channel and a drainage hole are formed between the guide rail and the outer peripheral wall of the gutter, and water that has entered between the panel and the opening is collected in the gutter.
The water in the gutter is drained from the drain hole to the outside through the drain channel.

(Problems to be Solved by the Invention) In the conventional panel, by setting a long distance between the pivot portion of the lifter and the roller of the slider, stable lifting and lowering operations and back and forth movement of the panel can be obtained. Therefore, it is necessary to make the length of the guide rail as long as possible, and the guide rail is formed so that one or both of its front and rear ends protrude forward and backward from the inner circumferential wall of the gutter. As a result, as shown in FIG. 6, the water flowing into the drainage channel 47 from the front and rear of the gutter section 41 does not flow into the drain hole 46, but between the protruding end 4a of the guide rail 40 and the inner circumferential wall section 42 of the gutter section 41. There is a problem in that the collected water 44 accumulates in the corner 43 between the gutter 41 and enters the vehicle interior by climbing over the inner circumferential wall 42 of the gutter 41 due to vibration or tilting of the vehicle.

The present invention aims to solve the above problems.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above object are as follows:
A gutter portion 7 corresponding to the entire periphery of the aperture portion 2 is provided below the opening portion 2, and a pair of left and right guide rails 12 for guiding the panel 4 in the front and rear direction are installed in the left and right side portions of the gutter portion 7. At least one of the end portions 12a and 12b is laid so as to protrude forward and backward from the inner circumferential wall portion 9 of the gutter portion 7, and the guide rail 12 and the gutter portion 7 are
A drainage channel 23 and a drainage hole 22 are provided between the outer peripheral wall 10 of
In the sunroof drainage device, the left and right inner parts 8a of the bottom wall parts 8 on the left and right sides of the gutter part 7 are formed higher than the outer parts 8b, and the guide rails 12 are fixed on the inner parts 8a. By that,
The water flowing in the front and rear portions of the gutter 7 is drained into the drainage channel 23 between the ends 12a and 12b of the guide rail 12 protruding from the inner peripheral wall 9 of the gutter 7 and the bottom wall 8 of the gutter 7. The point is that a flow path 13 is formed for flowing the water.

(Function) Water that has entered between the opening 2 formed in the vehicle roof 1 and the panel 4 that opens and closes this opening 2 is
The water in the gutter 7 below the opening 2 is collected by the guide rail 12 and the outer peripheral wall 10 of the gutter 7.
Pass through the drainage channel 23 formed between the drain hole 22
water is drained to the outside. At this time, the water flowing in the front and rear parts of the gutter section 7 flows through the water formed between the ends 12a and 12b of the guide rail 12 protruding from the inner circumferential wall section 9 of the gutter section 7 and the bottom wall section 8 of the gutter section 7. It flows smoothly into the drainage channel 23 through the flow path 13.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 to 3, a rectangular opening 2 is formed in the roof 1 of a vehicle, and a panel 4 bordered by a sealing member 3 is fitted into the opening 2 so as to be openable and closable. Lifters 15 having cam grooves 14 are attached to the lower surfaces of both left and right sides of the panel 4. A frame 5 is arranged below the opening 2, and the peripheral edge of the frame 5 is attached to the lower surface of the roof 1 over the entire circumference. A rectangular inner opening 6 that substantially corresponds to the opening 2 is formed in the frame 5, and a gutter portion 7 that corresponds to the entire periphery of the opening 2 is formed along the periphery of the inner opening 6. ing.

The gutter section 7 has a bottom wall section 8 and inner and outer peripheral wall sections 9 and 10.
It is formed in a U-shaped cross section with an upward opening. The bottom wall portions 8 on the left and right sides of the gutter portion 7 are formed such that the inner portions 8a thereof in the left and right direction are higher than the outer portions 8b of the inner circumferential wall portion 9 from the front to the rear.
And the inner part 8a where it is formed high
The front end is sloped outward and backward. Further, a drainage channel 23 is provided above the outer portion 8b. In addition, drain holes 22 are provided at the front and rear ends of the drain channel 23, respectively, and communicate with the drain pipe 24.
is formed so that water that has entered between the panel 4 and the opening 2 is received by the gutter portion 7, flows inside the gutter portion 7, and is discharged to the outside from the drain hole 22.

A pair of left and right guide rails 12 are fixed to the inner side portion 8a of the side portion of the gutter portion 7, and the guide rails 12 are in close contact with the inner circumferential wall portion 9 of the gutter portion 7, and the front and rear ends 12a, 12b are As shown in FIG. 5, they project forward and backward from the front and rear of the inner circumferential wall 9 of the gutter portion 7, respectively. Therefore, the guide rail 12
The front and rear ends 12a, 12b of the gutter 7 are separated from the bottom wall 8 of the gutter 7 to form a flow passage 13, and the water flowing through the front of the gutter 7 flows through the flow passage 13 as shown in FIG. The water flows smoothly into the drainage channel 23 through the water. The same applies to the water flowing through the rear part of the gutter section 7.

Further, opposing U-shaped guide grooves 16 are formed in the guide rail 12, and a support shaft 17 at the front part of the lifter 15 is rotatably and slidably slidable in the front and rear directions via a shoe 18 in the guide groove 16. At the same time, the slider 19 is fitted so as to be slidable in the front and rear directions via the shoe 20. The slider 19 has a roller 21 that slides in the cam groove 14 and raises and lowers the panel 4 around the support shaft 17.
is provided. This roller 21 is the cam groove 14
When the panel 4 is at the rear end, the panel 4 is tilted upward, and when the slider 19 is moved rearward in this state, the panel 4 is moved rearward and the opening 2 is opened.
The lifter 15 is provided with a stopper (not shown) that restricts the back and forth movement of the panel 4 when it goes up and down.

(Effect of the invention) According to the invention, between the ends 12a, 12b of the guide rail 12 protruding from the inner circumferential wall 9 of the gutter 7 and the bottom wall 8 of the gutter 7, The water flowing at the front and rear is channeled through the guide rail 12 and the outer peripheral wall 1 of the gutter section 7.
Since the flow path 13 is formed to flow into the drainage channel 23 formed between the trough section 7 and the trough section 7, the water flowing through the front and rear portions of the gutter section 7 flows between the protruding end of the guide rail and the inner circumferential wall of the gutter section, as in the conventional case. The water can flow smoothly into the drainage channel 23 through the flow path 13 without accumulating in the corners between the channels. Moreover, in the present invention, in particular, when forming the flow passage 13, the left and right inner portions 8a of the bottom wall portions 8 on the left and right sides of the gutter portion 7 are replaced with the outer portions 8b.
By forming the guide rail higher and fixing the guide rail on this inner part 8a, the protruding end of the guide rail 12 is separated from the bottom wall 8 of the gutter part 7, and the flow passage 13 is formed. This has the effect that the flow passage 13 can be formed widely, allowing a large amount of water to flow smoothly, and that a complicated structure is not required to form the flow passage 13.
