One embodiment will be described with reference to FIGS. 1 to 5. In this embodiment, a door trim 1 with a clip bracket as a board member with a bracket will be illustrated. Hereinafter, regarding a plurality of identical parts, one part will be given a reference numeral, and the other parts may be omitted.

A door trim 1 with a clip bracket according to the present embodiment has a plurality of clip brackets (an example of a bracket) 10 for holding clips 19 attached to a door trim (an example of a board member) 30 in a vehicle. That is, a plurality of clip brackets 10 formed as separate members from the door trim 30 are attached to the door trim 30. As shown in FIG. 1, each clip bracket 10 includes a rectangular plate-shaped mounting pedestal portion (an example of a pedestal portion) 11 and a clip seat 15 integrally formed with the mounting pedestal portion 11. When the plurality of clip brackets 10 are adjacent to each other, the mounting pedestals 11 are connected to each other by a connecting portion 20, thereby forming a bracket connection body 2 in which the plurality of clip brackets 10 are connected.

The mounting pedestal part 11 has a substantially rectangular plate shape, and two elongated through holes 12 (total four) extending in the transverse direction are provided at positions near both ends in the longitudinal direction. As shown in FIG. 4, on one surface side (back surface 11B) of the mounting pedestal portion 11, a plurality of protrusions 13 that protrude semispherically from the plate surface are provided in line along a pair of long sides ( (in this embodiment, four each). These protrusions 13 are for maintaining the separation distance of the mounting base portion 11 from the door trim 30 to a predetermined dimension.

In this embodiment, the thickness of the mounting base portion 11 is approximately 2.5 mm, and the protrusion dimension of the protrusion 13 is approximately 0.5 mm.

The clip seat 15 is provided on the other surface side (surface 11A) of the mounting base portion 11 at the center in the longitudinal direction. The clip seat 15 has a leg portion 16 having an arcuate cross section rising from the plate surface of the mounting pedestal portion 11, and a leg portion 16 that is approximately parallel to the plate surface of the mounting pedestal portion 11 on the tip side (upper side in FIG. 1) in the rising direction of the leg portion 16. A semicircular plate-shaped seat surface 17 is provided. A holding hole 18 into which a clip 19 can be attached is provided in the seat surface 17, and an entry path through which the clip 19 enters the holding hole 18 is formed by cutting out a portion of the peripheral edge of the holding hole 18. The clip 19 attached to the holding hole 18 is held in the vertical direction (direction intersecting the seat surface 17) by engaging with both the upper and lower surfaces of the seat surface 17 (see FIG. 5).

In this embodiment, the plurality of mounting pedestals 11 described above are connected by a connecting part 20. The connecting portion 20 has an elongated strip shape with a width narrower than the short side of the mounting pedestal portion 11, and integrally connects the plurality of mounting pedestals 11 in the longitudinal direction thereof.

A telescopic portion 21 is provided at the central portion of the connecting portion 20 in the extending direction. The extendable part 21 has a curved shape with a U-shaped cross section rising from the plate surface of the connecting part 20, and the extendable part 21 approaches the connecting part 20 by being stretched along the extending direction or pushed from both sides. This makes it possible for the mounting pedestals 11 arranged adjacent to each other to move closer to each other or move away from each other. Hereinafter, the portions of the connecting portion 20 other than the stretchable portion 21 (the portions on both sides of the stretchable portion 21) will be referred to as the connection holding portion 22.

In this embodiment, the thickness of the extensible portion 21 is set to be thinner than the thickness of the connection holding portion 22. Specifically, the plate thickness of the connection holding part 22 is about 2.5 mm, which is the same as that of the mounting base part 11, whereas the plate thickness of the extensible part 21 is about 2 mm.

As the resin constituting the clip bracket 10 described above, thermoplastic resins such as polyethylene, polypropylene, polyethylene terephthalate, and polylactic acid can be used.

On the other hand, the door trim 30 to which the clip bracket 10 is attached includes fibers and thermoplastic resin. For example, kenaf fiber is used as the fiber included in the door trim 30, but the type of fiber is not limited thereto. As the fibers used for the door trim 30, wood fibers, thermoplastic resin fibers, glass fibers, carbon fibers, etc. may be used. Further, in the door trim 30, the fibers are bound by a thermoplastic resin as a binder. Examples of the thermoplastic resin used as a binder for the door trim 30 include polyester resins such as polypropylene and polyethylene. The resin contained in the door trim 30 may be the same resin as the resin constituting the clip bracket 10, or may be a different resin.

Note that in this embodiment, the door trim 30 does not include a covering material (see FIGS. 3 to 5), and its design surface 30A takes advantage of the texture of the fiber-containing resin material that constitutes the door trim 30. .

The clip bracket 10 described above can be made into a door trim by applying hot melt 28 to the back surface 11B of the mounting pedestal 11 and adhering the mounting pedestal 11 to the surface (back surface 30B) opposite to the designed surface 30A of the door trim 30. 30 (see FIGS. 4 and 5). The hot melt 28 applied between the mounting pedestal 11 and the door trim 30 is pinched and crushed between them, but the plurality of protrusions 13 provided on the back surface 11B of the mounting pedestal 11 are pressed against the back surface 30B of the door trim 30. By contacting them, the distance between them is kept constant (see FIG. 4). In other words, the posture of the mounting base portion 11 relative to the door trim 30 is maintained stably. Note that the excess hot melt 28 can be released into the through hole 12 as well as the outer periphery of the mounting base portion 11.

Further, in such an attached state, the connecting portion 20 is in a free state with respect to the door trim 30.

The clip bracket-equipped door trim 1 of this embodiment is as described above, and its effects will now be described. A door trim 1 with a clip bracket according to the present embodiment includes a plurality of clip brackets 10, each clip bracket 10 includes a mounting pedestal 11, and each clip bracket 10 is attached to a door trim 30 via the mounting pedestal 11. Adjacent mounting base portions 11 are connected to each other by a connecting portion 20 having an expandable and retractable portion 21.

According to the above configuration, since the plurality of clip brackets 10 are connected by the connecting portion 20, the effort of adjusting the orientation and position of each clip bracket 10 can be saved, and the work of attaching the clip brackets 10 to the door trim 30 can be simplified. Moreover, even if the door trim 30 and the clip bracket 10 have manufacturing tolerances, installation tolerances, etc., the expansion and contraction of the expansion and contraction part 21 provided in the connection part 20 can absorb the positional deviation between them.

Further, the extendable portion 21 has a curved shape that curves in a direction intersecting the mounting surface of the mounting base portion 11 to the door trim 30. By forming the stretchable portion 21 into a curved shape in this manner, the stretchable portion 21 can be stretched along the extending direction of the connecting portion 20 or pushed from both sides to approach the connecting portion 20 .

Further, the thickness of the elastic part 21 is set smaller than the thickness of the connection holding part 22. According to such a configuration, while the extensible portion 21 can be flexibly expanded and contracted, the connection holding portion 22 can accurately maintain the connection posture and arrangement of the plurality of mounting pedestals 11.

Furthermore, the clip bracket 10 and the door trim 30 are made of different materials. According to such a configuration, even if the clip bracket 10 and the door trim 30 expand and contract in different dimensions due to differences in thermal expansion coefficients, the expansion and contraction of the expansion and contraction part 21 makes it possible to absorb the positional shift of the attachment part. . Thus, deformation of the door trim 30 (door trim 1 with clip bracket) can be suppressed.

Further, the door trim 30 is made of a material containing fibers and thermoplastic resin, and the surface opposite to the surface to which the clip bracket 10 is attached (back surface 30B) is a designed surface 30A of the door trim 30.

As described above, according to the door trim 1 with clip brackets of the present embodiment, a plurality of clip brackets 10 can be easily attached to the door trim 30, and positional displacement is unlikely to occur.
