Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a spacer of a hollow member attached to a panel of varying angle of inclination.

2. Description of the Related Art In order to improve the aerodynamic characteristics of an automobile, an air spoiler 12 is known which is attached to the rear end of the vehicle body, for example, the upper surface of a trunk lid 11, as shown in FIG. This air spoiler 12 is
Generally, it is a hollow shape with an open bottom and is integrally molded from hard synthetic resin.
A spacer made of soft synthetic resin, rubber, or the like is interposed between the vehicle body panel and the vehicle body panel, and then the vehicle body panel is screwed to the vehicle body panel. That is, as shown in FIG.
5, and a strip-shaped spacer is arranged along the bottom surface of each wall portion.

Problems to be Solved by the Invention Here, the front wall portion 13, rear wall portion 14, and side wall portion 15 of the air spoiler 12 have different inclination angles with respect to the vehicle body panel surface. FIG. 6 shows the inclined state of each wall section in an overlapping manner. In the air spoiler 12 of this example, the rear wall section 14
is the closest to vertical, and the front wall 13 is more inclined than this, and the side wall 15 is even more inclined than the front wall 13. Each wall of the air spoiler 12 is formed to have approximately the same thickness, but as a result of having different inclination angles as described above, the width l of the bottom surface of the wall facing the vehicle body panel surface is
As shown in the figure, is also the narrowest in the rear wall portion 14,
It is widest at the side wall portion 15 and is intermediate between the two at the front wall portion 13.

Therefore, it is difficult to integrally form spacers disposed around the entire circumference of the air spoiler 12 with the same cross-sectional shape by extrusion molding, and the spacers disposed around the entire circumference of the air spoiler 12 have the same cross-sectional shape. There was no choice but to take a method such as extrusion molding according to the cross-sectional shape and molding the parts corresponding to the side wall portions 15 to connect them. As a result, the process is complicated and the manufacturing cost is high.

Means for Solving the Problems A spacer for a hollow member according to the present invention is an integrally extruded spacer disposed along the bottom surface of a wall of the hollow member and interposed between it and a panel. , a flexible base portion held between the bottom surface of the wall portion of the hollow member and the panel; a decorative piece formed at one end of the base portion to cover the outer peripheral edge of the wall portion of the hollow member; a protrusion piece formed on the other end of the base portion; and a protrusion piece protrudingly formed on the bottom surface of the protrusion offset portion of the base portion, when the bottom surface of the wall portion of the hollow member is less than or equal to a predetermined width, the protrusion offset portion of the base portion and a support piece for keeping the holder in an upright position.

Function The spacer is extruded to have the same cross-sectional shape, and is attached along the bottom surface of the wall of the hollow member. Here, in a portion where the width of the bottom surface of the wall portion of the hollow member is greater than a predetermined width, the support piece is crushed by the bottom surface of the wall portion of the hollow member, so that the base portion is in a substantially flat state. At this time, the protruding piece substantially contacts the inner circumferential surface of the wall of the hollow member.

In addition, in areas where the width of the bottom of the wall is less than the specified width,
Since only the portion of the base portion that is closer to the decorative side than the support piece is pressed by the bottom surface of the wall, the portion of the base portion that is closer to the decorative side is brought into an upright state by the support piece. Then, the protruding piece at the tip of the upright portion comes into contact with or approaches the inner circumferential surface of the hollow member wall. That is,
The substantial width of the spacer will vary depending on the width of the bottom of the hollow member wall.

Embodiment FIG. 1 is a sectional view showing an embodiment of a spacer 1 according to the present invention. This spacer 1 is integrally extruded from soft synthetic resin or rubber, and includes a flexible flat band-shaped base portion 2 and a hook-shaped portion extending upward from one end of the base portion 2. a decorative piece 3, a protrusion piece 4 formed to protrude upward from the other end of the base part 2, and a support piece 5 formed to protrude obliquely from the bottom surface of the base part 2 near the protrusion piece 4. have. The decorative piece 3 is curved inward so as to cover the outer peripheral edge of each wall portion of the air spoiler 12, and considering the inclination angle of the side wall portion 15 which is the most inclined, The angle is set so that there are no gaps. Note that one end of the base portion 2 to which the decorative piece 3 is connected is slightly bent downward. Further, the height of the protruding piece 4 and the distance from the decorative piece 3 to the protruding piece 4 are set in consideration of the cross-sectional shape of the side wall portion 15 having the largest slope, as will be described later. The formation position of the support piece 5, that is, the distance from the decorative piece 3, is set to be slightly larger than the width of the bottom surface of the front wall 13 and the rear wall 14.

Now, the spacer 1 configured as above is
It is arranged along the four sides of the air spoiler 12 and interposed between it and a vehicle body panel 6 such as a trunk lid. Then, the air spoiler 12 is fixed to the vehicle body panel 6 using screws while sandwiching the spacer 1 therebetween.

FIG. 2 shows a state in which the spacer 1 is attached to the rear wall portion 14 that is most vertical. In this rear wall portion 14, the width of the wall bottom surface is smaller than the distance from the decorative piece 3 to the support piece 5, and only the portion on the outer peripheral side of the support piece 5 is pressed from above. Therefore, the portion of the base portion 2 closer to the projection piece 4 is connected to the support piece 5.
It is kept in an upright state by the protruding piece 4 at the tip.
comes into contact with the inner circumferential surface of the rear wall portion 14. Therefore, the actual width of the spacer 1 is narrower than the entire width of the base portion 2, and the decorative piece 3 is brought into close contact with the outer circumferential surface of the rear wall portion 14 without any gaps to ensure good appearance quality. Misalignment is prevented.

Although the front wall 13 has a larger slope and a wider bottom surface than the rear wall 14, the difference is relatively small and the mounting condition is similar to that shown in Fig. 2. Become.

Next, FIG. 3 shows how the spacer 1 is attached to the side wall portion 15 having the largest slope. In this side wall portion 15, the width of the bottom surface is larger than the distance from the decorative piece 3 to the support piece 5, and the support piece 5
The bottom surface of the side wall portion 15 presses against the base portion 2 in a wide range including the portion. Therefore, the support piece 5 is in a crushed state as shown in the figure, and the entire base portion 2 is maintained in a substantially flat state. At this time, the projection piece 4 is brought into contact with the inner circumferential surface of the side wall portion 15. Therefore, also in this side wall portion 15 portion, the decorative piece 3 is brought into close contact with the outer circumferential surface of the side wall portion 15 without any gaps to ensure good appearance quality, and the spacer 1
This prevents the mounting position from shifting.

Note that the spacer 1 may be attached to the air spoiler 12 in advance with double-sided tape or the like.

Note that the present invention is not limited to air spoilers, but can also be applied to spacers for mounting hollow members such as bumpers and finishers.

Effects of the Invention As is clear from the above description, according to the present invention, the substantial width of the spacer disposed along the bottom surface of the wall of the hollow member is made to correspond to the width of the bottom surface of the wall, It is possible to prevent the generation of gaps and misalignment of the mounting position, and it is possible to use spacers with the same cross-sectional shape all around the hollow member. Therefore, the entire spacer can be integrally extruded and the processing cost can be reduced.
