Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drip molding for an automobile for preventing rainwater from flowing from a front window or a roof to a side window during running and hindering a driver's side view.
[0002]
[Prior art]
As shown in FIG. 5, the drip molding includes a window pad 1 and a roof pad 2, where the window pad 1 is a connecting portion between the side panel 3 and the front window W of the vehicle body, and the roof pad 2 is the side panel. 3 and the roof R are attached to the connecting portions, respectively, to prevent water from flowing out from the connecting portions to the side window side.
[0003]
As shown in FIGS. 6 to 8, the molding is configured by covering a core material 4 made of a metal plate formed by a roll forming method with a covering material 5 made of plastic or rubber by extrusion molding.
[0004]
Further, over the entire length of the molding, one side portion in the width direction of the covering material 5 is extended downward to form the first lip portion 6, and the opposite side portion is extended sideways to form the second lip portion 7, respectively. As shown in FIGS. 6 and 7, the first lip portion 6 contacts the surface of the front window W as shown in FIGS. 6 and 7, and the roof butt portion 2 contacts the roof R as shown in FIG.
[0005]
6 is a cross-sectional view of an intermediate portion in the front-rear direction of the window pad portion 1, and FIG. 7 is a cross-sectional view of the rear end portion (portion connected to the roof pad portion 2).
[0006]
On the other hand, the second lip portion 7 contacts the side panel 3 at both the window pad portion 1 and the roof pad portion 2 to perform a sealing action.
[0007]
Here, as shown in FIGS. 6 to 8, the cross-sectional shape of the side panel 3 is different between both connection portions, and the height dimension of the window connection portion (FIGS. 6 and 7) of the panel 3 is the roof connection portion (see FIG. 6). 8) is larger than the height dimension, and the steps A and B between the window W or the roof R and the side panel 3 are different in size, so that the molding cross-sectional shape corresponding to the difference between the step dimensions A and B, that is, The downward protrusion amount C of the first lip portion 6 needs to be large at the window pad portion 1 and small at the roof pad portion 2.
[0008]
As one of the countermeasures, although not shown in the figure, means for connecting both parts 1 and 2 as separate members having different cross-sectional shapes by joints is taken. There was a difficulty that it looked bad.
[0009]
Therefore, in general, both the parts 1 and 2 are formed continuously and integrally, and the protrusion C of the first lip part 6 is increased at the window pad part 1 by the roof pad part 2 at the time of molding or after the molding. A method is adopted in which the difference between the step sizes A and B is formed by being formed to be small.
[0010]
In this case, the protrusion amount C of the first lip portion 6 in the window pad portion 1 needs to be reduced at the rear end portion connected to the roof pad portion 2 in accordance with the change in the step dimensions A and B. The protrusion amount C at the window pad 1 is gradually reduced from the front end toward the rear end.
[0011]
[Problems to be solved by the invention]
However, according to the configuration of this conventional integral molding, the protrusion amount C (= mall height dimension) of the first lip portion 6 is small at the rear end portion of the window pad portion 1 as described above. When a large amount of water is pushed into this part due to the operation of the wiper, etc., as shown by the arrow in FIG. 7, the water easily gets over the mall and flows to the front part of the side window, which hinders the driver's side view. There was a problem.
[0012]
The roof abutment portion 2 also has a small first lip protrusion amount C, but the driver does not push in a large amount of water due to the wiper operation as in the rear end portion of the window abutment, and if the water gets over the driver. Because it is from the middle to the rear side of the side window that is out of the side view, there is almost no problem.
[0013]
Therefore, the present invention provides a drip molding for automobiles that can prevent water from getting over from the rear end of the window pad.
[0014]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided an automotive vehicle in which a window pad portion attached to a connection portion between a side panel and a front window of a vehicle body and a roof pad portion attached to a connection portion between the side panel and the roof are continuously formed integrally. In the drip molding, a plastic or rubber outer lip and inner lip are projected downward on one side of the molding width direction as a lip that contacts the windshield or roof, and a space is formed between them. In the state, the outer lip portion is opposed to the window in a state where a gap is formed between the windows, and at the same time, the outer lip portion prevents back flow of water in the space. is set to a dimension that serves the weir, in the roof support part in contact with the roof, the inner lip, with the window support part The roof abutting portion is in contact with the window and is located in a recessed groove formed in a connecting portion between the roof and the side panel, and in this state, the space communicates with the recessed groove. is there.
[0015]
According to a second aspect of the present invention, in the configuration of the first aspect, the protruding amount of the inner lip portion gradually decreases from the front end to the rear end of the window pad portion, and the roof pad portion has a constant size at the rear end of the window pad portion. It is what has become .
[0016]
According to a third aspect of the present invention, in the configuration of the first or second aspect, a step is formed between the outer surface of the outer lip portion and the outer surface of one end portion in the molding width direction so as to form the rain gutter portion in the molding mounting state. is there.
[0017]
According to the above configuration, in the integrated drip molding, as the lip portion that contacts the front window or the roof (corresponding to the first lip portion 6 in the description of the prior art), it contacts the roof (does not contact the front window). An outer lip portion and an inner lip portion that contacts the front window are provided at a distance from each other on the left and right sides, and the inner lip portion is located in a concave groove formed in a connection portion between the roof and the side panel at the roof pad portion. Therefore, the water pushed into the rear end portion of the window pad portion enters the space between the two lip portions, flows from here into the concave groove, and is discharged.
[0018]
Further, at this time, the outer lip portion serves as a dam that prevents water that has entered the space between the lip portions from flowing back to the front window side.
[0019]
By the action of these two points, it is possible to reliably prevent water from flowing over the rear end portion of the window pad and flowing to the side window and obstructing the field of view.
[0020]
According to the second aspect of the present invention, the amount of protrusion of the inner lip portion is reduced by the roof abutting portion. Therefore, even if the inner lip portion is positioned in the concave groove as described above, It is not necessary to make the groove deeper so that it does not hit the bottom of the groove. For this reason, there is no possibility that the living space in the vehicle is narrowed by deepening the concave groove.
[0021]
According to the configuration of the third aspect, the rain gutter portion (取 付) is formed by the step provided between the outer surface of the outer lip portion and the outer surface of the one end portion in the molding width direction in the molding mounting state. Overflow of rainwater is suppressed.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
[0023]
1 and 2 and the roof abutting part 12 shown in FIG. 3 are integrally formed continuously, and the window abutting part 11 is composed of the front window W and the side panel 3. The roof abutting portion 12 is attached to the connecting portion between the roof R and the side panel 3. 13 is a core material formed by roll forming a metal plate material, and 14 is a covering material mounted on the outer periphery of the core material 13 by extrusion molding.
[0024]
1 shows an intermediate portion of the window pad 11 corresponding to FIG. 6, and FIG. 2 shows a rear end of the window pad (connecting part with the roof pad 12) corresponding to FIG.
[0025]
In this drip molding, an outer lip portion 15 and an inner lip portion 16 are provided on one side in the width direction of the covering material 14 as a lip portion corresponding to the conventional first lip portion 6 shown in FIGS. And a second lip portion 17 corresponding to the conventional second lip portion 7 (in contact with the side panel 3) on the opposite side. Is projected sideways.
[0026]
The lip portions 15, 16, and 17 are provided in both the window abutting portion 11 and the roof abutting portion 12. Of these, the outer and inner lip portions 15, 16 are projected and positioned so as to satisfy the following requirements. Relationship is set.
[0027]
(B) an outer lip portion 15 faces in a state where the gap α is formed with respect to the wind contact part 11 in the front window W as shown in FIGS. 1 and 2, the roof rest part 12 as shown in FIG. 3 Contact the roof R.
[0028]
( B ) The inner lip portion 16 is in contact with the front window W in the window pad portion 11 as shown in FIG. 1, and is formed at the connecting portion between the roof R and the side panel 3 in the roof pad portion 12 as shown in FIG. In this state, the space S communicates with the concave groove 18.
[0029]
According to this drip molding, the inner lip portion 16 that comes into contact with the window W at the window abutting portion 11 is located in the concave groove 18 at the roof abutting portion 12 as described above ( b ) . The water pushed into the rear end portion of the window pad 11 enters the space S between the lip portions 15 and 16 and flows from here into the groove 18 as shown in FIG. It is discharged outside.
[0030]
Further, at this time, the outer lip portion 15 serves as a weir that prevents the water that has entered the space S from flowing back to the front window side as shown by the broken line arrow in FIG. .
[0031]
For this reason, there is no possibility that the water will get over the rear end of the window pad and flow to the front part of the side window and hinder the driver's side view.
[0032]
Further, a step β (see FIG. 3) is provided between the outer surface of the outer lip portion 15 and the outer surface of one end portion in the width direction of the molding (covering material 14).
[0033]
By this step β, a rain gutter portion G is formed between the roof R and the roof R in the mall mounted state, and this rain gutter portion G acts as a rain gutter, so that it is possible to suppress water overpass at the roof abutting portion 12. .
[0034]
The protrusion amount D of the inner lip portion 16 gradually decreases from the front end to the rear end of the window abutting portion 11 as shown in FIG. 4 and the like, and the roof abutting portion 12 has a rear end (the broken line in FIG. 4). It is constant in the dimension of the part marked with.
[0035]
By doing so, the protrusion amount D of the lip portion is reduced at the roof abutting portion 12, so that the lip portion 16 does not hit the bottom of the groove 18 even if the inner lip portion 16 is positioned in the groove 18. It is not necessary to make the groove 18 deeper. For this reason, the evil that the living space in a vehicle is narrowed by deepening the ditch | groove 18 does not arise .
[0036]
【The invention's effect】
As described above, according to the present invention, in the integrated drip molding, the lip portion that contacts the front window or the roof has a double structure including the outer lip portion and the inner lip portion, and the inner lip portion is the roof abutting portion. Because it is configured to be positioned in the groove formed in the connecting part of the roof and the side panel, the water pushed into the rear end portion of the window pad flows into the groove through the space between the lip portions. This can be discharged to the outside as a passage.
[0037]
At this time, backflow of water that has entered the space can be prevented by the weir action of the outer lip portion.
[0038]
By these two actions, it is possible to reliably prevent water from flowing over the rear end portion of the window pad and flowing to the front portion of the side window and hindering the driver's side view.
