Description

[Detailed explanation of the idea] The present invention relates to a cover device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 2 designates a structure such as a center pillar or rear pillar of an automobile, in which an inner pillar 4 and an outer pillar 6 extending in the longitudinal direction are welded to flanges 8 and 8' formed on both side edges, respectively, to form a closed cross section. It consists of

12 indicates a cover device, one flange 8,
It has a first cover 14 that covers the other flanges 8', 10' and a second cover 16.

The first cover 14 is formed into a sheath shape with a U-shaped cross section, and ribs 18 and 20 that abut the flange 8 or 10 are formed at appropriate locations on the inside, and claws 22 pointing inward are formed on the outside. A guide 26 is formed, which is disposed at a position facing the claw 22 and opens outward. The protrusion 24 and the guide 26 are integrally formed on the first cover 14 as engaged parts.

The second cover 16 has a first folding flange 28 that coversly engages the flanges 8' and 10', and a first
a second folding flange 30 that engages with the cover 14 so as to cover the second folding flange 30;
A clip 36 having an outwardly directed claw 34 is formed inside the side body 32. A clip 36 serving as an engaging portion is integrally formed with the second cover 16.

The first cover 14 and the second cover 16 are each integrally formed of synthetic resin such as polypropylene or ABS resin.

In the above-mentioned cover device, the first cover 14 is first engaged so as to cover the flanges 8 and 10, and the first bent flange 28 of the second cover 16 is engaged with the flanges 8' and 10'. The elasticity of the second bending flange 30 causes the second bending flange 30 to be opened outward and placed so as to cover the first cover 14. At this time, the claw 34 of the clip 36 of the second cover 16
is guided by the guide 26 of the first cover 14 and engaged with the claw 22 of the protrusion 24. In this case, protrusion 2
4 and the clip 36 are the flanges 8, 10, 8',
Allowing relative displacement along the protruding direction of 10',
It is configured to be engageable.

Therefore, according to this embodiment, the protrusion 24 and the clip 36 are provided on the first cover 14 and the second cover 16.
are integrally formed, so both covers 1
4 and 16 can be placed on the structure 2 without using any tools or other metal clip members, resulting in excellent assembly efficiency and cost reduction due to the reduction of parts. Further, the position of the protrusion 24 on the first cover 14 or the position of the clip 36 on the second cover 16 may be different between the two covers 14 and 16.
Even if the flanges 8, 10, 8', and 10' are formed to be slightly shifted from each other along the protruding direction during assembly, the protrusion 24 and the clip 36 are engaged with each other while allowing the relative displacement. Therefore, both covers 1
It is possible to assemble the parts 4 and 16 even if the dimensional control during manufacturing is relaxed.

Furthermore, according to this embodiment, the quality due to manufacturing errors between the parts is only visible in FIG.
