Abstract

PURPOSE:To prevent a sunroof from rusting by providing the outer wall of a gutter disposed on a sunroof frame with a water discharge tube connected to the inside of the gutter, connecting a connection tube surrounding the water discharge tube to the frame, attaching a seal member between the connection tube and the drain tube, and connecting a drain tube to the connection tube. CONSTITUTION:Rain or other water entering through the gap between the circumference of a window 3 and a sunroof panel 6 is received with a gutter 13 made of rubber or plastic and flows through a water drain passage 21 to a drain tube 29. Even if a reverse flow occurs in the drain tube 29, water is prevented with a seal member 22 from entering the connection tube 20 and further from entering a sunroof frame 4. As the drain tube 29 is connected to the connection tube 20 surrounding the drain passage 21, the drain tube 29 may be made with a material of a thick diameter having less low resistance. As the drain passage 21 has nothing to do with the connection of the drain tube 29, the passage as well as the gutter 13 may be formed with a soft material such as rubber.

Description

[Detailed Description of the Invention] A. Object of the Invention (1) Industrial Application Field The present invention relates to a sunroof device applied to the roof of a vehicle, mainly an automobile, and in particular to a sunroof panel that opens and closes a window opening in the roof plate of a vehicle body, and a sunroof device that is applied to the roof of a vehicle body. The present invention relates to an improved view including a sunroof frame disposed below and supporting a sunroof panel.

(2) Conventional technology Conventionally, in visible sunroof devices, a gutter extending along the periphery of the window is attached to the sunroof frame in order to discharge rainwater that has entered between the periphery of the window and the sunroof panel to the outside of the vehicle. A drainage structure in which the sunroof frame is connected to a drain tube that communicates with the gutter is widely used. (3) Problems to be Solved by the Invention However, since sunroof frames are generally made of steel plates, if the gutter that receives rainwater that enters the frame is integrated, the rainwater will cause the gutter to rust over a long period of time. This may occur. When this rust flakes off, there is a risk that it will clog the drain tube and impede drainage.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a simple and effective sunroof device capable of preventing rusting of the sunroof frame due to infiltrating rainwater.

B. Structure of the Invention (11. Means for Solving the Problems) In order to achieve the above object, the present invention provides a gutter made of synthetic resin that extends along the periphery of the window and installs it on the sunroof frame. A drain pipe that communicates with the interior of the wall is provided protrudingly, a connecting pipe that surrounds this drain pipe is connected to the frame, and a sealing member is installed between the connecting pipe and the drain pipe, and the connecting pipe is connected to the connecting pipe. It is characterized by a drain tube connected.

(2) Function According to the above-mentioned structure, rainwater, etc. that has entered between the periphery of the window and the sunroof panel is collected by a gutter made of rubber or synthetic resin, and flows out to the drain tube via the drain pipe. Even if a backflow of water occurs in the drain tube, the sealing member prevents water from entering the connecting pipe, thereby making it possible to prevent water from entering the frame from the connecting pipe.

Further, since the drain tube is connected to a connecting pipe surrounding the drain pipe, a thick one with less resistance to the flow path can be used.

Furthermore, since the drain pipe is not involved in the connection of the drain tube, it is possible to form the drain pipe with a soft material such as rubber together with the gutter.

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, a quadrilateral window 3 is provided in the front part of a roof plate 2 in a vehicle body 1 of an automobile. Further, a quadrilateral picture frame-shaped sunroof frame 4 is disposed directly below the roof plate 2 along its periphery. A pair of guide rails 5, 5 are provided on both left and right sides of the sunroof frame 4.
are fixed in parallel, and a sunroof panel 6 for opening and closing the window 3 is supported by these guide rails 5.5.

That is, as shown in FIGS. 2 and 3, each guide rail 5 is composed of an outer rail portion 5a and an inner rail portion 5b adjacent to the inner side of the outer rail portion 5a. A front slider 7 fixed to the inner rail part 5b is slidably engaged with the inner rail part 5b, and is connected to the rear part of the panel 6 via a tilt mechanism 8.
is slidably engaged with the outer rail portion 5a.

The tilt mechanism 8 is a known mechanism that tilts the rear part of the sunroof panel 6 up and down at a position facing the window 3 when the sunroof panel 6 is opened and closed.

An operating cable 10 is connected to the rear slider 9 as shown in FIGS. 1 and 3, and this operating cable 10 connects to an electric motor 1 installed on the rear side of the sunroof frame 4.
Push/pull operation is performed by 1.

When the sunroof panel 6 is in the closed position, the slider 9 which pulls the operation cable 10 by the electric motor 11 moves the sunroof panel 6 through the tilt mechanism 8.
The window 3 can be opened by tilting down the rear part of the vehicle and moving the sunroof panel 6 backward. Also,
If the operating cable 10 is pushed from this state, the sunroof panel 6 will move forward, and at the forward limit, the rear end will be tilted.
Window 3 can be closed by popping it.

The periphery of the sunroof panel 6 has a window 3 in its closed position.
A weather strip l2 is attached that is in close contact with the inner circumferential surface of the weather strip.

On the top surface of the sunroof frame 4 is a quadrilateral frame-shaped gutter l3.
will be installed. This gutter 13 is made of rubber, and the elastic locking part 14 on the outer periphery of the gutter 13 connects to the flange part 15 on the outer periphery of the sunroof frame 4.
is engaged with. Further, a seal portion l6 that is in close contact with the inner surface of the roof plate 2 is integrally formed on the outer peripheral edge of the gutter l3.

This gutter 13 is arranged so that its open surface is directly below the drain wall 17 that hangs down from the periphery of the window 3. Further, both ends of a communication gutter (not shown) located directly below the rear edge of the window 3 are connected to both left and right sides of the gutter l3.

As shown in FIGS. 1 and 4, the sunroof frame 4
Connecting pipes 20 are welded to the outer walls of the four corners of the gutter 13, and drain pipes 21 passing through the connecting pipes 20 are integrally provided to protrude from the outer walls of the four corners of the gutter 13.

A rubber seal member 22 is installed between the connecting pipe 20 and the drain pipe 2l as follows.

That is, as clearly shown in FIG. 5, the sealing member 22 includes a cylindrical portion 23 and a pair of inner and outer lips 24 and 25 formed at one end of the cylindrical portion 23 and projecting obliquely toward the other end. , a flange '26 formed on the outer periphery of the other end of the cylindrical part 23
and an annular projection 27 formed on the inner periphery of the other end. When the sealing member 22 is inserted between the connecting pipe 20 and the drain pipe 2l with the lips 24 and 25 at the top, the inner lip 24 is attached to the outer peripheral surface of the drain pipe 21, and the outer lip 25 is attached to the outer peripheral surface of the connecting pipe 20. Each adheres closely to the inner peripheral surface. Furthermore, the annular projection 27 fits into the outer peripheral surface of the drain pipe 2l, and the flange 26 abuts on the end surface of the connecting pipe 20, thereby regulating the mounting posture of the seal member 22.

Note that the flange 26 may have a lip that can come into close contact with the inner peripheral surface of the drain tube 29, which will be described later.

An annular sealing protrusion 28 is formed on the outer circumferential surface of the end of the connecting tube 20, and the upper end of the drain tube 29 is fitted into the connecting tube 20 so as to be in close contact with the sealing protrusion 28, and fixed with a clip 30. be done.

As shown in FIG. 1, the drain tube 29 is arranged in a hollow part of the villa 31 that is connected to a corner part of the roof board 2.

The hollow part of the billet 31 communicates with a drain hole (not shown) provided at the bottom of the vehicle body 1, and the drain tube 29
The water flowing out can be discharged to the outside.

In FIGS. 2 and 3, 32 is a sunshade panel that is slidably supported on the inner rail portion 5b, and 33 is a roof lining that covers the lower surface of the sunroof frame 4 and is fixed to the roof plate 2.

Next, the operation of this embodiment will be explained.

When rainwater or the like enters between the periphery of the window 3 and the sunroof panel 6, the water passes through the draining plate 17, falls into the gutter 13, flows toward the drain pipe 2I located at a low place, and is drained from the drain pipe. It flows out into the drain tube 29 through 2L.

By the way, while the vehicle is running, the water that once flowed from the drain pipe 2l to the drain tube 29 may flow back due to vibrations, etc. In this case, the space between the connecting pipe 20 and the drain pipe 21 is sealed by the sealing member 22. Therefore, the backflow water cannot enter between the connecting pipe 20 and the drain pipe 210,
As a result, water is prevented from entering the sunroof frame 4 from the connecting pipe 20.

At that time, the seal member 22 is attached to the drain pipe 21 of the annular projection 27.
The fitting to the outer peripheral surface and the abutment of the flange 26 to the end surface of the connecting tube 20 ensure that it is always maintained in an appropriate position, so that a good sealing function can be exhibited for a long period of time.

In this way, the sunroof frame 4 is cut off from contact with water entering through the window 3 and water flowing back through the drain tube 29, and no leakage occurs.

Moreover, the drain tube 29 connects the drain pipe 21 with
Since it is connected to the surrounding connecting pipe 20, a thick pipe with less flow path resistance can be used. Furthermore, since the drain pipe 21 is not involved in the connection of the drain tube 29, even if it is made of soft rubber like the gutter 13, it will not interfere with the connection work of the drain tube 29. In the present invention, the gutter I3 may be made of synthetic resin.

C. Effects of the Invention As described above, according to the present invention, a plastic gutter extending along the periphery of the window is installed above the sunroof frame, and a drain pipe communicating with the inside of the gutter is protruded from the outer wall of the gutter. A connecting pipe that surrounds this drain pipe is connected to the frame, a sealing member is installed between the connecting pipe and the drain pipe, and a drain tube is connected to the connecting pipe, so that water cannot enter through the window. The sunroof frame is protected by the gutter and the seal member from water and water flowing back through the drain tube, and this can be prevented. Moreover, - the drain tube is connected to the connecting pipe surrounding the drain pipe, so
A thick one with low flow resistance can be used, and drainage can be done quickly. Furthermore, the material used for the drain pipe, which is not involved in the connection of the drain tube, can be freely selected, regardless of whether it is soft or hard.
