Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for combining hollow members for constituting a pair of hollow members overlapped with each other, such as a luggage floor lid for opening and closing an opening of a luggage storage box of an automobile.

  The conventional hollow member structure constructed by adopting this type of mating structure is not only a luggage floor lid that opens and closes an opening of a luggage storage box of an automobile, but also, for example, an armrest mounted on a floor lid and a door trim in a trunk room And side impact pads, rear parcels, tonneau boards, etc.

  These hollow member structures are formed by superposing and attaching a pair of hollow members to each other.

The hollow member constituting body 20 is formed by, for example, attaching the overlapping surfaces 21a and 22a of the pair of hollow members 21 and 22 to each other like a luggage floor lid shown in FIG. It has a matching structure (see Patent Document 1).
Japanese Patent Laid-Open No. 10-129353.

  The paired hollow members 21 and 22 are specifically formed by forming a recessed portion 21c on the exposed surface 21b side of one hollow member 21 and using the bottom wall of the recessed portion 21c as a clip seat 21d. The clip hole 21e is formed, and the clip 23 is inserted through the clip hole 21e.

  Further, the overlapping surface 22a of the other hollow member 22 is formed with an engagement hole 22c penetrating into the hollow portion 22b. By engaging the clip 21d with the engagement hole 22c, both the hollow members 21, The hollow member constituting body 20 having an integral structure is formed by superposing 22 members together.

  In the conventional combined structure of the hollow members configured as described above, the clip 23 is used to superpose the hollow members 21 and 22, and the leg side of the clip 23 is processed in the other hollow portion 22b. Thus, although it does not appear on the surface side of the other hollow member 22, the head side of the clip 23 appears on the exposed surface 21b side of the one hollow member 21 from the clip hole 21e, and the protrusion Since it becomes a thing, it accommodates by forming the recessed part 21c, and it is made not to protrude on the surface 21b of one hollow member 21. FIG.

  For this reason, the head of the clip 22b is exposed to the recessed portion 21c, and it cannot be denied that it looks bad, and dust is accumulated in the recessed portion 21c during use. It is very troublesome to remove this, and in order to prevent this, it is conceivable to close the recess 21c by providing a cap (not shown), but in order to insert and engage the cap, It is necessary to form a claw portion for hooking and attaching the cap to the side wall of the recessed portion 21c. By providing this claw portion, the recessed portion 21c has an undercut structure when one of the hollow members 21 is formed, and the slide type Etc., and the cost of the product is increased.

  Therefore, in view of the above, the present invention provides a hollow member mating structure configured such that a mounting tool such as a clip for mating and mounting a pair of hollow members does not appear on the exposed surface of the hollow member. It is an object.

In order to achieve the above object, the hollow member mating structure according to the present invention is a hollow member mating structure in which a pair of hollow members is formed by superposing the overlapping surfaces thereof, and the pair of hollow members The bracket member is attached to the overlapping surface side of one of the hollow members, a clip insertion hole is formed in the bracket member, and a retaining flat plate portion on one end side of the clip body inserted into the clip insertion hole is provided. Positioned in a clip installation recess formed on the overlapping surface of the one hollow member, the clip body is hooked on the bracket member after the bracket member is mounted on the one hollow member, and the retaining plate is hooked on the bracket member. , and the stop state exits from the clip insertion hole, by Rukoto is inserted a clip portion at the other end of the clip body from the front clip insertion hole, wherein The lip portion is protruded from the polymerization surface side of said one hollow member, and, by engaging the clip portion, the clip engagement hole formed in the polymerization surface side of the other hollow member, wherein The structure is characterized in that both hollow members are mounted by polymerization.

  In the present invention configured as described above, since the bracket member is attached to the overlapping surface side of one hollow member and the overlapping surface side of the other hollow member is attached to the bracket member, the hollow members are overlapped with each other. Even if a mounting tool such as a clip is used for mounting, the mounting tool can be configured not to be exposed on the exposed surface side of the hollow member. It is not necessary to form the recessed portion 21c or the like as described above, which contributes to improving the appearance and does not accumulate dust, and does not require a conventional closing structure with a cap to the recessed portion 21c. The cost of the product can be reduced without the undercut structure.
