Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window molding which surrounds an outer peripheral edge of a window glass of a flip-up type back door of a vehicle, and more particularly to a drainage structure thereof.

[0002]

2. Description of the Related Art In general, van-type vehicles and wagon-type vehicles generally have a structure shown in FIG.
As shown in FIG. 1, a flip-up type back door 3 is used which hinges an upper end edge to a rear end edge of a vehicle body roof 1 and pivots up and down to open and close a back door opening 2 of the vehicle body. A window opening is formed in the upper half of the back door 3,
A window glass 4 is fixed to an opening edge of the window opening via a window molding 5 surrounding the outer periphery thereof. The back door 3 is generally opened to a more upright angle than horizontal to facilitate loading and unloading operations.

[0003]

By the way, when the back door 3 is fully opened at the time of rainfall, most of the rainwater received by the window glass 4 moves forward as shown by white arrows in FIGS. Since the windshield 4 flows down and is received by the front window molding 5, and the window glass 4 is generally curved in the width direction, the rainwater flows right and left along the inner peripheral edge of the window molding 5 and collects at the corner 52 of the window molding 5.
The collected rainwater climbs over the wind mall 5 and wraps around the left and right side edges of the back door 3, and a part of the rain falls into the vehicle interior, or an unillustrated lining provided at the back door opening edge of the vehicle body. In the process of traveling along the strip and flowing along the strip, it may fall into the passenger compartment and wet the passenger compartment and cargo. Therefore, the present invention has been made to prevent such rainwater from falling into the vehicle interior.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a flip-up type back door, which wraps around the outer edge of a window glass, traverses the window molding and extends over the surface of the window glass. A protruding rainwater guide portion is formed (claim 1). The rainwater received by the window glass and flowing to the corner along the window molding is received by the extension of the rainwater guide, guided by the guide, and discharged to the front of the corner.

[0005] In the present invention, the rainwater guide portion is formed at two positions, that is, a center of the corner of the wind mall and a position near the center of the back door which is close to the center of the corner. By sharing the rainwater discharge between the two rainwater guides, it is possible to cope with a large amount of rainfall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a back door 3 for opening and closing a door opening 2 of a van type car can be flipped up to an angle which stands more than horizontal. In the upper half of the back door 2, a window opening surrounded by a door frame 31 is formed, and a window glass 4 is installed in the opening.

[0007] On the outer peripheral edge of the window glass 4, a window molding 5 surrounding the window glass 4 is attached. Wind Mall 5
The linear general portion 51 is a rubber extruded body, and the corners 52 at the four corners are rubber molded bodies, which are integrally joined when the corner 52 is molded. As shown in FIG. 4A (showing a general portion on the upper edge side) and FIG. 4B (showing one side edge on the left and right sides), the window molding 5 has a groove 50 on the entire inner circumference. The peripheral edge of the window glass 4 is fitted to this.

The upper portion of the window glass 4 and the inner surfaces of the left and right outer peripheral portions are bonded and fixed to the door frame 31 with an adhesive 6. The inner peripheral surface of the lower portion is similarly bonded and fixed to the upper edge of the main body of the back door 3 forming the lower edge of the window opening with an adhesive. Reference numeral 7 denotes a dam for preventing the protrusion when the adhesive 6 is applied. The lip 511 is formed on the outer peripheral side of the general portion on the upper edge side and the lower edge side of the door glass 4 among the linear general portions 51 of the wind molding 5, and the step portion 311 of the outer plate 31a of the door frame 31 and The back door 3 is in close contact with a step (not shown) of the main body. The left and right width of the window glass 4 is the left and right door frames 3.
1 and the general portions 51 on the left and right of the window molding 5, as shown in FIG.
A lip 512 covering the side edge of is formed. A trim 8 that closes a gap between the inner peripheral edge and the inner surface of the window glass 4 is attached to the inner peripheral edge of the door frame 31.

FIG. 2 shows one of the left and right upper corner portions 52 of the wind molding 5. The surface of the molded corner portion 52 has a rainwater guide projecting in a direction connecting the center of the inner peripheral edge and the outer peripheral edge. The portion 53 is formed in a straight line. The rainwater guide portion 53 has a corner portion inner peripheral side extending further than the inner peripheral edge.
It is pressed against the surface. The width of the rainwater guide portion 53 is uniform, approximately 3 to 12 mm, and the protruding height is higher on the inner peripheral side of the corner portion and is about 4 to 6 mm on the inner peripheral side. The length of the extension 31 is about 15 to 20 mm.

In the back door 3 in which the rainwater guide section 53 is formed at the corner 52 of the window molding 5, when the load is flipped up to the fully open position during rainfall and the cargo is loaded, the rainwater received by the window glass 4 Most of them flow downward and forward. This rainwater is received by the front window molding 5 as shown by the white arrow in FIG. 2 (A) and flows in the left-right direction along the inner peripheral edge thereof, and most of the rainwater is extended by the extension 531 of the rainwater guide 53. I can take it. This water further flows along the rainwater guide section 53 across the corner section 52 and is discharged to the front of the back door.

In this case, since the flow direction of the rainwater along the rainwater guide portion 53 is obliquely outward toward the front of the vehicle, the rainwater is discharged to the outside of the side of the rear portion of the body roof, and the discharged rainwater is discharged from the back door opening. From 2 directly into the cabin,
Alternatively, it does not flow down the back door opening edge. A part of the rainwater received by the window glass 4 flows along the window moldings 5 on the left and right side edges and is discharged from the corner portion 52 outside the rainwater guide portion 53.
The amount is relatively small, and even if a part of it falls into the cabin, it does not cause any harm.

FIG. 3 shows another embodiment of the present invention. The same rainwater guide portion 53 as in the previous embodiment is formed at the center of the corner portion 52 of the molding of the wind molding 5. Further, a rainwater guide portion 53A having substantially the same shape and size as the rainwater guide portion 53 is formed at an end of the corner portion 52 on the center side of the back door in a direction orthogonal to the wind molding 5. The distance from the rainwater guide portion 53 is about 100 mm between both ends on the outer peripheral side of the window molding. Other structures are substantially the same as the previous embodiment.

When the back door 3 is fully opened during the rainfall and the cargo is to be loaded, the rainwater received at the center of the window glass 4 flows downward as shown by the white arrow in the figure, and the inner periphery of the window molding 5 Flows in the left-right direction along with and is received by the extension 531A of the rainwater guide 53A. Then, it is guided by the rainwater guide portion 53A and crosses the window molding 5 to be discharged onto the roof 1 (FIG. 1). Part of the drained rainwater is removed from the roof 1 via the pillars and out of the vehicle.
Another part of the rainwater is received by a drain groove (not shown) formed at the opening edge of the back door of the vehicle body to drain the rainwater on the roof, and is drained down. On the other hand, the rainwater received by the left and right portions of the window glass 3 flows downward, is guided by the rainwater guide portion, and is discharged to the outside of the side surface of the roof.

If the rainwater guide 53 is formed only at the center of the corner of the corner 52 of the wind molding 5, the purpose can be sufficiently achieved when the amount of rainfall is about 0.05 mm / min or less. However, when the rainfall exceeds that, the rain collected at the corners is
To the side edge of the wind mall 5. By increasing the height of the rainwater guide portion 53, it is possible to reduce the passage of rainwater, but there is a limit to the height of the appearance around the door. Therefore, the rainwater guide 53A is provided together with the rainwater guide 53, and the removal of the rainwater received at the center and the end of the window glass 3 is shared by the two rainwater guides 53 and 53A, thereby coping with a large amount of rainfall. .

[0015]

According to the present invention, in the case of a back door of a vehicle that can be flipped up higher than horizontal, when the back door is fully opened to load and unload during rainfall, rainwater received by the window glass of the back door. Does not get around the back door and drip into the passenger compartment, and does not wet the passenger compartment or cargo.
