BACKGROUND OF THE INVENTION
The present invention relates to a seal structure for an open car having a hood that can be folded open.
[0002]
[Prior art]
FIG. 5 is a side view showing an example of a seal structure of an open car having a hood 1 in which a roof can be folded and opened.
The hood 1 is opened and closed as a plurality of links (not shown) located at the left and right ends of the roof rotate in the longitudinal direction of the vehicle body, and each link has a terminal portion of a side glass G that moves up and down. Weather strips 5a and 5b in which hollow seal portions 6a and 6b which are elastically contacted are integrally formed are respectively attached via retainers. When the hood is opened, the opposite end portions of the adjacent weather strips 5a and 5b are brought into contact with each other to seal the outside of the vehicle interior.
[0003]
When the roof is opened, the folded hood portion 1 is stored in the lower part on the rear side of the vehicle body. When the roof is closed, the front end of the hood 1 is in contact with the header 3 and the upper end portion of the front pillar 4 that fix the upper end of the windshield 2 as shown in FIG. It is like that.
[0004]
Conventionally, the abutting portion between the opposite ends of the weather strips 5a and 5b has been formed by aligning a vertical end surface or an inclined end surface formed by molding, so that water leaked from the outer seal side is moved to the inner seal side. There was a problem of getting into the passenger compartment.
[0005]
[Problems to be solved by the invention]
As a countermeasure against this, as shown in FIGS. 6 to 9, a concave portion 7 and a convex portion 8 are formed on both end surfaces of the abutting portions of the weather strips 5 a (FIG. 6) and 5 b (FIG. 7) at the time of abutting (FIG. 8) The two are fitted to each other, or a concave portion is formed on the end surface of one weather strip (for example, the front side) and a convex portion is formed on the end surface of the other weather strip (for example, the rear side). There is one with improved sealing performance by fitting. Conventionally, since there are many three-fold hood types, as shown in FIG. 8, the fulcrum Y when opening and closing the weather strip 5a on the front side is in the vicinity of the butt portion or behind the butt portion and is located on the rear side of the butt portion. The strip 5a is rotated counterclockwise in FIG.
[0006]
However, if the accuracy of fitting by the concave portions 7 and the convex portions 8 formed on both end faces is poor, as shown in FIG. 9, gaps 9 and steps are generated in the hollow seal portions 6a and 6b, thereby lowering the sealing function. It was a cause. Therefore, in the past, the soft sponge 10 was applied to stop the water that had oozed from the abutting surfaces. However, when the hood 1 is opened, the water accumulated in the recess 7 may fall and be immersed in the vehicle. there were. There are also holes that are provided in both end faces of the abutting portion in order to guide the water accumulated in the concave portion 7 to the outside and drain it. There was a problem of water leaking from the butt when the accuracy of the was poor.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals. FIG. 1 shows an end portion of the front weather strip that constitutes the seal structure according to the embodiment of the present invention, and FIG. 2 shows an end portion of the rear weather strip.
[0017]
The seal structure according to the embodiment of the present invention includes a hood 1 that can be folded and opened by rotating a plurality of links (not shown) in the front-rear direction of the vehicle body. Weather strips 15a and 15b that can be folded in two before and after the hollow seal portions 16a and 16b that are elastically contacted with the ends of the side glass G that moves up and down are attached to the ends. When the hood 1 is opened, the opposite ends of the front and rear weather strips 15a and 15b are brought into contact with each other as shown in FIG. 3 and FIG. It has become.
[0018]
As shown in FIG. 1, a V-shaped convex portion 21 having a top portion facing downward is formed at the rear end portion of the front weather strip 15a that is abutted against each other. Further, a V-shaped concave portion 22 having a downward top is formed in the front end portion of the rear weather strip 15b. The shape of the V-shaped concave portion 22 is substantially equal to the shape of the V-shaped convex portion 21, and the convex portion 21 is fitted into the concave portion 22 when the roof is closed.
[0019]
The fitting of the convex portion 21 and the concave portion 22 is performed by sliding the end faces to be faced in parallel directions. More specifically, as shown in FIG. 3, the opening / closing fulcrum X when the front weather strip 15 a is bent is positioned in front of the abutting portion with the rear weather strip 15 b, and the convex portion 21 with respect to the concave portion 22. The concave portion 22 and the convex portion 21 are fitted so as to be slid from above and overlapped so that the end faces are abutted with each other.

Elastically contact with each other without generating a step in the width direction.
[0021]
Holes leading to the hollow seal portions 16a and 16b are formed at the lower position of the convex portion 21 formed at the rear end portion of the front weather strip 15a and at the lower position of the concave portion 22 formed at the front end portion of the rear weather strip 15b, respectively. 25 and 26 are formed, and a drainage groove 27 is formed between the lower apex of the recess 22 and the hole 26.
As a result, the water that has entered the abutting portion is guided into the hollow seal portions 16a and 16b via the drainage grooves 27 and the holes 25 and 26.
[0022]
Further, a water receiving lip 29 is formed at a lower position of the hole 25 formed in the rear end portion of the front weather strip 15a. The water receiving lip 29 is formed toward the rear weather strip 15b, and is arranged so as to receive the front end portion of the rear weather strip 15b that is abutted against the front weather strip 15a from below when the roof is closed.
As a result, water that has entered the abutting portion and has not been guided to the holes 25 and 26 is also received by the water receiving lip 29, and is guided into the hollow seal portion 16b through the hole 26 when the roof (top) is opened.
[0023]
In addition, as shown in FIG. 3, although the abutting surface by both the weather strips 15a and 15b was slanted, it is not restricted to this, It can also be set as the perpendicular | vertical state which does not provide an inclination.
[0024]
【The invention's effect】
As described above, according to the seal structure of the open car according to the first aspect, when the roof is closed, the V-shaped convex portion formed at the rear end portion of the front weather strip is formed at the front end portion of the rear weather strip. Since it is fitted to the V-shaped concave portion, the meshing is stabilized as compared with the butt end matching.
Further, the engagement is configured such that the convex portion is fitted to the concave portion by utilizing the rotation of the front weatherstrip when the roof is closed, so that the sealing performance between the end faces is high. Moreover, since the shape of the convex part and the concave part is V-shaped, the assembly accuracy is poor, and even if the end faces are a little shifted in the width direction, they are corrected naturally. As a result, since the front weatherstrip and the rear weatherstrip are flush with each other, the seal surfaces of the hollow seal portions of both weatherstrips are elastically flush with the side glass without causing a step in the width direction. Can be touched.
[0025]
Further, according to the invention described in claim 2, in addition to the function and effect of the invention described in claim 1, a hole is formed in the end portion where both weather strips are abutted, and water that has entered the abutting portion passes through the hole. Since it is guided into the hollow seal portion, water can be prevented from entering the vehicle. Further, the water drainage groove formed at the rear end portion of the front weather strip ensures that the water that has entered the recess formed in the rear weather strip from the butted portion is guided to the lower hole.
[0026]
Further, according to the invention described in claim 3, in addition to the function and effect of the invention described in claim 2, the water receiving lip formed at the rear end portion of the front weatherstrip enters the butted portion and leads to the hole. When the roof is opened, the water is guided from the hole on the upper side of the water receiving lip into the hollow seal portion of the front weather strip, thereby further preventing the water from entering the vehicle.
