Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roof drip molding which is attached to a channel panel by a plurality of L-shaped clips which are engaged with an engagement groove at an end of a side surface of the channel panel to cover a channel panel constituting a roof drip channel. The present invention relates to a waterproof structure of a roof drip molding of an automobile for waterproofing between panels.
[0002]
[Prior art]
As shown in FIG. 5, this type of roof drip molding 10 extends in the front-rear direction along the roof side, and descends before and after that to reach the belt molding 4. The roof drip channel 8 covered by the roof drip molding is, as shown in FIGS. 3 and 4, a roof panel 2 and a channel panel bottom surface 1a and a channel panel side surface bent in an orthogonal direction at an end outside the vehicle compartment. 1b, and a channel panel bottom surface 1a is joined to a roof panel 2, a roof side rail 3, and front and rear front and quarter panels.
[0003]
Reference numeral 9 denotes a synthetic resin clip for attaching the roof drip molding 10 to the channel panel 1. The U-shaped engaging groove 9a is engaged with the tip of the channel panel side surface 1b. And a base portion 9b that is in contact with the base portion 9b. A plurality of the clips are arranged at intervals along the roof drip molding 10.
[0004]
The roof drip molding 10 rises along the molding panel bottom surface 12a along the channel panel bottom surface 1a and the channel panel side surface 1b, and further projects so as to partially cover the opening 8a of the roof drip channel 8. The molding body 10A made of stainless steel having the molding side surface 11 bent to the middle is covered from the molding bottom surface 12 to the middle of the molding side surface 11 with a covering portion 15 made of synthetic resin, for example, vinyl chloride. A lip 14 made of synthetic resin is joined to the portion. The covering portion 15 extends toward the interior of the vehicle so as to contact the side surface of the body.
[0005]
The roof drip molding engages with a concave engaging groove 17 corresponding to the projection 9c formed at the tip of the clip 9, and a concave engaging groove corresponding to the projecting portion 9d of the base 9b. It is attached to the channel panel 1 by engaging at 16. Further, a sponge 7 is mounted between the channel panel side 1b and the molding side 11 as a waterproof structure for preventing rainwater from entering between them. In a portion where the clip 9 is set, the clip 9 is attached to the molding side surface 11 in a compressed state according to its thickness.
[0006]
[Problems to be solved by the invention]
However, in this type of waterproof structure, at the position where the clip 9 is set, a gap is formed in the sponge 7 due to a step portion due to the thickness thereof. However, there is a possibility that rainwater may drop onto the rocker portion or the floor, and rainwater may also enter from the engaging groove 9a of the clip 9.
[0007]
Therefore, an object of the present invention is to provide a waterproof structure of a roof drip molding that can improve waterproofness in this type of roof drip molding.
[0008]
[Means for Solving the Problems]
In order to achieve this object, according to the present invention, in order to cover a channel panel constituting a roof drip channel, the present invention raises a molding bottom along a channel panel bottom and a channel bottom along a channel panel side. A metal plate having a molding side bent toward the interior of the vehicle, at least a bottom surface of the molding is covered with a synthetic resin, and a plurality of Ls engaged with a front end of the channel panel side by an engagement groove. In a waterproof structure of a roof drip molding of an automobile for waterproofing a roof drip molding attached to a channel panel with a letter-shaped clip between channel panels, the roof drip molding is adjacent to an edge of a base along a channel panel bottom surface. In the area, the synthetic resin covering the bottom surface of the molding is raised and abuts on the edge and the bottom surface of the channel panel. And wherein the forming the-up.
[0009]
The lip abuts against the bottom of the channel panel to provide waterproofing between the bottom of the channel panel and the bottom of the molding. Also, by contacting the edge of the base of the clip, the clip holds the roof drip molding with the engagement groove engaging with the side surface of the channel panel. According to the second aspect, even when the roof drip molding is formed only of a synthetic resin, a lip having the same function can be formed.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
A waterproof structure of a roof drip molding of an automobile according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In these figures, the same parts as those described in FIGS. 3 to 5 are denoted by the same reference numerals and will not be described in detail.
[0011]
The roof drip molding 20 is configured by covering a stainless steel molding main body 10A having a molding bottom surface 12 and a molding side surface 11 with a covering portion 25 made of vinyl chloride from the molding bottom surface 12 to the middle of the molding side surface 11. Specifically, it has the same structure as the above-described conventional roof drip molding 10. Similarly, the roof drip channel 8 is constituted by the roof panel 2 and the channel panel 1, and the clip 9 is formed in an L-shape having an engagement groove 9a and a base 9b.
[0012]
According to the present invention, the covering portion 25 protrudes in a region adjacent to the edge 26 of the base portion 9b of the clip 9 along the channel panel bottom surface 1a, so that the channel panel bottom surface 1a and the edge 26 are elastically contacted. The contact lip 29 is formed integrally. As shown in FIG. 2, the shape is such that a clip contact surface 29a which is orthogonal to the molding bottom surface 12 so as to make surface contact with the edge 26, and a back surface 29b which is easy to bend and is inclined so as to gradually taper. Are formed in a triangular cross section. This lip extends over the entire length of the roof drip molding 20.
[0013]
As a result, the gap between the channel panel bottom surface 1a and the molding bottom surface 12 is sealed by the lip 29 at a position closer to the vehicle interior than the clip 9 to form a double waterproof structure with the sponge 7. The narrowed distal end of the lip 29 flexibly bends and abuts on the channel panel bottom surface 1a with elasticity so as not to displace the molding bottom surface 12 away from the channel panel bottom surface 1a. In addition, the roof drip molding 20 has a reliable engagement shape in which the lip abutment surface 29a of the lip 29 located at a position further than the protruding portion 9d with respect to the engagement groove 9a is orthogonal to the edge 26 of the clip 9. The clip is held by the clip 9, so that the roof drip molding 20 is reliably prevented from rolling or wobbling.
[0014]
According to the present invention, instead of the above-described embodiment, the sponge 7 is eliminated, or the projecting portion 9d of the base 9b of the clip 9 and the corresponding engaging groove 16 of the roof drip molding 20 are formed. It is also possible to have a simple configuration for forming a flat shape without performing. Further, the present invention is applicable to a roof channel molding in which the molding side surfaces and the molding bottom are formed in a similar shape only with a synthetic resin having elasticity, instead of the metal body coated with resin. .
[0015]
【The invention's effect】
According to the first or second aspect of the present invention, since the seal portion is formed in a portion different from the clip, it is possible to avoid a decrease in waterproof performance due to the thickness of the clip. Further, by increasing the distance between the engaging groove engaging with the clip and the other engaging portion, the holding force of the roof drip molding by the clip can be improved. According to the third aspect of the present invention, since the distal end portion is easily bent, it is possible to reliably seal without impairing the holding performance of the clip.
