DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure of a windshield molding, and more particularly, to a vehicle having a cargo in which a vertically rotatable windshield is provided on the left and right sides, the cargo side windshield is inclined. The present invention relates to a drainage structure that ensures that rainwater falling on a windshield is introduced into a window-side weatherstrip when it is flipped upward.

[0002]

2. Description of the Related Art In a vehicle 4 having a box-shaped cargo 2 disposed at the rear as shown in FIG. 4, a vertical windshield 6 may be provided on the left and right cargo sides 2a of the vehicle 4. . Such a vertically-rotatable windshield 6 can normally be held in a state of being opened obliquely upward by a damper stay 8 or the like, but if the windshield 6 is opened obliquely upward in rainy weather. The rainwater that has fallen on the windshield 6 flows toward the upper part of the window. In this case, if the upper edge 6a of the windshield 6 is located above the weather strip 10 on the window side,
Even with a small amount of rainfall, the entire amount of rainwater almost certainly flows into the weather strip 10. However, in the windshield 6 of the cargo side 2a, when the windshield 6 is opened, the upper edge 6a is separated from the weather strip 10 on the window side toward the outside of the vehicle body as shown in FIG. If no countermeasures are taken, rainwater flowing down the windshield 6 directly enters the vehicle interior R through the window opening 12.

For this reason, a resin molding 14 having a groove 14a for guiding rainwater is provided on a peripheral portion of the conventional windshield 6 with reference to FIGS. 1 to 3 showing an embodiment of the present invention. The upper part of the window side weather strip 10 from the molding 14 is attached to the molding 14 at a proper position (usually a position hidden inside the hinge cover 16 of the two hinge portions 17 fixed with the bolts 19a of the windshield 6). A gutter-shaped drainage portion 14b extending to the bottom is integrally formed. Then, as shown in FIG. 3, the rainwater W that has fallen on the windshield 6
b, and flows down from the drainage portion 14b to the window side weather strip 10. Note that in FIG.
9a and 19b are bolts, and the hinge bracket portion 1
8 and the hinge cover 16 are fixed to the cargo side 2a and the windshield 6, respectively.

[0004]

In the conventional drainage structure, there is no particular problem in drainage when the amount of rainfall when the windshield 6 is opened diagonally upward is very small. From the window opening 12 to the vehicle interior R
There is a risk of intrusion into

That is, when the amount of rain is very small, the entire amount of the hinge bracket 1 is determined by the gap between the hinge bracket 18 of the windshield 6 and the hinge cover 16.
8 and flows downward from both sides of the hinge bracket portion 18 as indicated by arrows in FIG. 1 (B) and is received by the window side weather strip 10.

However, as the rainfall increases, the flow velocity of the rainwater flowing down the draining portion 14b increases in proportion to the rainfall, and the entire amount of the rainwater flows into the weather strip 10 along the route indicated by the arrow in FIG. It becomes difficult to do. As a result, a part of the rainwater overflows from the tip of the drainage portion 14b through the upper surface and the outer surface of the pivot support portion 18a of the hinge bracket portion 18, and drops in the direction shown by the arrow in FIG. The possibility that some of the water droplets enter the vehicle interior R from the window opening 12 increases.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the flow of rainwater flowing down a drain portion to reliably introduce rainwater into a window side weather strip even when the amount of rainfall increases to some extent, thereby preventing rainwater from flowing into the window opening. Is to do.

[0008]

In order to solve the above-mentioned problems, the structure of the drain portion of the windshield molding according to the present invention is arranged such that a weather strip is disposed above a window on a vehicle body side on which a weather strip is disposed along a peripheral edge portion. A windshield disposed so as to be openable and closable in the vertical direction around the hinge portion of the edge, a molding having a rainwater guide groove disposed at least along the upper edge of the windshield, and a base end portion. weather tip with communicates with the groove of the mall of the window side
A gutter-shaped drain portion extending to a position above the strip; and a convex portion (20) formed on the bottom wall surface of the drain portion (14b) and serving as a resistance to rainwater flow , wherein the convex portion (20 ) But rainwater flow
A plurality of triangular protrusions (20) formed in a plurality of columns in a downward direction.
And one apex (20c) of each triangle points in the direction of rainwater
It is characterized in that it is formed so as to be oriented to

[0009] It is preferable that a plurality of the protrusions are formed in a cascade in the flowing direction of the rainwater, and each one of the protrusions is a triangular protrusion formed to be directed in the flowing direction of the rainwater. As a result, the straight side of the triangular convex portion is perpendicular to the flow path of the drainage portion, and the rainwater colliding with the drain portion consumes the flow velocity energy and flows along the one side. Rainwater flowing down from both ends is drawn to the center in the width direction of the drainage channel along two oblique straight sides of a triangle, and another one adjacent in the downstream direction from one vertex pointing in the flowing direction It collides with one straight side of the triangular convex portion, where the flow velocity energy is consumed again. Thereafter, it is brought to the center in the width direction of the flow path of the water draining portion along two oblique straight sides of the triangular shape. Then, at a sufficiently low speed, the water flows down from the tip of the drain portion to the weather strip on the window side.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1A, 2 and 3, the drainage portion 14b of the present invention is characterized in that a triangular convex portion 20 is formed on the bottom wall surface of the drainage portion 14b. The convex portion 20 may be formed integrally with the drain portion 14b, or the convex portion 20 may be manufactured separately and the drain portion 14b may be formed with an adhesive or the like.
It may be adhered on the bottom wall surface of b. The convex portion 20 is for suppressing the flow rate of rainwater, and various shapes other than a triangle can be adopted as the convex shape as long as it has such a flow velocity suppressing action. In the present embodiment, in order to increase the flow velocity suppressing action as much as possible, a triangular (isosceles triangle or equilateral triangle) convex portion 20 is employed.

More specifically, a plurality of triangular projections 20 are formed in cascade in the direction of rainwater flow, and one of each triangle is formed.
The two tops point in the direction of rainwater flow. By arranging the two triangular protrusions 20 forward and backward along the flow direction of rainwater in this way, the flow rate of rainwater can be effectively suppressed.

That is, the straight side 20a of the triangular projection 20 is at right angles to the flow path of the draining portion 14b, and the rainwater colliding with the drain 20b consumes the flow velocity energy.
After flowing along the line a, the rainwater that has flowed down from both ends of the one side portion 20a is brought to the center in the width direction of the flow path of the drainage portion 14b along the triangular oblique straight two side portions 20b, and It collides with one linear side 20a of another triangular projection 20 adjacent in the downstream direction from one directed vertex 20c, where the flow velocity energy is consumed again. It is moved to the center in the width direction of the drainage part 14b along the part 20b and flows down from the tip of the drainage part 14b to the window side weather strip 10 at a sufficiently low speed.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the drainage of the cargo side windshield 6 is performed. Although the present invention has been applied to the partial structure, the present invention can be similarly applied to other windshields in which the upper edge of the windshield is located outside the window side weather strip when the windshield is opened.

[0014]

As described above, according to the present invention, since the convex portion serving as the resistance of rainwater to flow down is formed on the bottom wall surface of the drainage portion, even if the rainfall increases and the amount of water flowing down the drainage portion increases. In addition, the flow rate of rainwater at the drain portion can be suppressed, and the rainwater can be reliably introduced into the window side weather strip.
