BACKGROUND OF THE INVENTION
The present invention relates to a seal structure for a weather strip for a door. More specifically, for example, in a vehicle having a double door such as an ambulance, the present invention relates to a seal structure for a door weather strip attached to the upper end portion of a parting portion of a left and right door constituting the double door.
[0002]
[Prior art]
As shown in FIGS. 3 and 4, for example, a back door of a vehicle such as an ambulance is a double door, and an annular door weather strip 3 is attached to the left door 1 constituting the double door, and the right door 2. Is attached with a substantially U-shaped door weather strip 4 having an opening on the left door 1 side. When the left door 1 and the right door 2 are closed, the door weather strips 3 and 4 are elastically contacted with a body panel (not shown) to seal the interior and exterior, and the door weather strip 3 is positioned on the left side of the right door 2. It is designed to seal the parting between the doors by elastic contact with the end.
Three corner portions 3A, 3B, 3C, 4A, 4B, and 4C of the weather strips 3 and 4 for doors are mold forming portions, and the other portions are extrusion forming portions.
The left door 1 and the right door 2 have glass windows 5 and 6 and a handle 7 attached thereto. Further, a drip weather strip 9 is attached to the roof portion at the upper end of the body panel so that the upper ends of the left and right doors 1 and 2 elastically contact when the door is closed.
[0003]
FIG. 5 shows an enlarged perspective view of the corner portion 4B serving as the upper mold forming portion of the weather strip 4 for doors. In the conventional double door, the door weather strip 4 is assembled to the right door upper end 2A, as shown in FIG. 5, for example, as a recess between the rear beads 11, 12 formed on the mounting surface of the door weather strip 4. The shape of the convex portion 13 that fits in is formed on the mold forming portion (there is also the shape of the convex portion that fits into the concave portion between the back beads 10, 11). Further, the mold forming portion 4B and the door weather strip 4 are fixed to the right door upper end portion 2A by clips 14a, 14b, and 14c.
The door weather strip 4 is formed with a lip portion 16 that elastically contacts the body when the door is closed, as well as a hollow seal portion 15 that elastically contacts the body when the door is closed and seals the interior and exterior. Further, the end 17 extending from the hollow seal portion 15 of the door weather strip 4 is elastically contacted with the hollow seal portion of the left door weather strip and is sealed (not shown).
[0004]
[Problems to be solved by the invention]
However, the assembling of the door weather strip 4 to the right door upper end portion 2A shown in FIG. 5 is performed by the convex portion 13 that fits into the concave portion between the rear beads 11 and 12 formed on the mounting surface of the door weather strip 4. Therefore, the door weatherstrip 4 is unstablely fixed. Further, the shape of the convex portion 13 is not the peripheral portion 13a of the terminal portion, and since it is assembled by the clips 14a, 14b, 14c, the fixing interval between the clips is insufficient due to the mounting interval of the clips. The position of the door weather strip 4 in the direction) is unstable.
For this reason, if a sealing bead is formed on the base surface 19 to improve the sealing effect, the door weatherstrip 4 is lifted from the upper right end 2A of the right door, so that the sealing bead cannot be provided, and a leak occurs. There is a problem that occurs.
