Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap used for attaching automobile decorative members such as spoilers and moldings to automobile panels.

[0002]

[Prior art]

 Some automobile decorative members such as spoilers and moldings have a portion called a boss protruding from a part thereof, or a clip is attached to the decorative member integrally or separately. The vehicle panel is provided with circular or square mounting holes. A collar portion that comes into contact with the automobile panel to prevent the cap from coming off and a cap that is tubular and has a protrusion for preventing the cap from coming off are attached to the mounting hole. Further, when a hat-shaped mounting seat is provided on the decorative member, a clip having an engaging portion that engages with this mounting seat is mounted via this mounting seat. A boss portion of the decorative member or a clip attached to the decorative member via a mounting seat engages with the cap, and the decorative member is attached to an automobile panel.

As an example, attachment of the spoiler 3 to the trunk panel 4 will be described with reference to FIG.

The spoiler 3 is composed of a main body 31 having substantially the same width as the trunk panel 4, and a stay 32 supporting the main body 31. The clip 2 is embedded in the stay 32 of the spoiler 3 by insert molding when the spoiler 3 is blow molded. The clip 2 is engaged with a cap 6 attached to the trunk panel 4. As shown in FIG. 1, the clip 2 includes a brim-shaped spoiler attachment portion 25, a cross-section + shaped shaft portion 21 connected to the spoiler attachment portion 25, and a barbed engagement portion 22 provided at the tip thereof. As shown in FIG. 5, the cap 6 is composed of a circular collar portion 61 and a cylindrical base portion 62 connected to the collar portion 61. On a part of the inner peripheral surface of the cylindrical base portion 62, a rib 63 having a triangular cross section is formed over the entire circumference. Further, one portion of the outer peripheral surface of the base portion 62 is provided with a retaining projection 64 having a triangular cross-section in vertical section to prevent the trunk panel 4 from retaining.

[0005]

[Problems to be solved by the device]

 The outer diameter of the base portion 62 of the cap 6 is set to be substantially the same as the hole diameter of the mounting hole 41 provided in the trunk panel 4. Further, the cylindrical base portion 62 is shaped like a bag toward the tip thereof. In order to engage the clip 2 attached to the spoiler 3 with the cap 6, the rib 63 of the cap 6 is bent outward by an overlapping amount with the engaging protrusion 22 of the clip 2. There must be. In order to facilitate the work of attaching the clip 2 to the cap 6, it is necessary to reduce the overlap margin, but the clip 2 is easily removed from the cap 6. On the contrary, if the overlap margin is increased, the workability of attaching the clip 2 to the cap 6 is deteriorated.

Therefore, an object of the present invention is to provide a cap that improves the workability of attaching a decorative member to an automobile panel and can be securely fixed to the automobile panel.

[Means for Solving the Problems]

 A cap, which is attached to a circular mounting hole formed in an automobile panel and which is attached to a boss portion provided on a decorative member for an automobile or a mounting seat of the decorative member, is configured as follows. The cap is composed of a collar portion that comes into contact with an automobile panel and a tubular base portion that is connected to the collar portion and that has an elliptical cross section. An inner protrusion that engages with the boss or clip is provided, and an outer protrusion that engages with the mounting hole is provided on the outer peripheral surface of the base along the major axis direction thereof.

[0008]

[Action]

 A boss provided on an automobile decorative member or a clip attached to a mounting seat of the decorative member is provided with an inner protrusion of a tubular base having an elliptical cross section when engaging with the cap. The portion flexes and deforms in a gap formed between the base portion and the mounting hole.

[0009]

【Example】

 The present invention will be described with reference to FIGS. 1 to 4 for a cap 1 used when the spoiler 3 is attached to the trunk panel 4. The spoiler 3 is arranged at the rear end of the trunk panel 4, and is attached to the trunk panel 4 via a clip 2 embedded in the stay 32 and a nut 5 embedded in the seating surface of the spoiler 3. As shown in FIG. 1, the clip 2 is provided with a spoiler attachment portion 25 to which the two collars 24, 24 are connected by a cylindrical shaft portion 23. At the lower part of the spoiler mounting portion 25, there are provided a shaft portion 21 having a cross-shaped + shape and a ridge-shaped engagement projection 22 that is connected to the shaft portion 21. The cap 1 is composed of a collar portion 11 that abuts on the trunk panel 4, and a base portion 12 that is connected to the collar portion 11 and has an elliptical cross section and is tubular. The flange portion 11 is set to a size capable of closing the periphery of the circular mounting hole 41 formed in the trunk panel 4. When a sealing property is required for the mounting hole 41 as in the present embodiment, the seal packing 17 that surrounds a part of the outer peripheral surface of the cylindrical base portion 12 is in contact with the lower surface of the collar portion 11. , It is fitted into the cap 1. A cylindrical base 12 having an elliptical cross section is connected to the collar 11. Since the mounting hole 41 of the trunk panel 4 is formed in a circular shape, a gap 43 is formed between the base portion 12 and the mounting hole 41 as shown in FIG. The space surrounded by the inner peripheral surface of the base portion 12 is a clip insertion portion 15 having an elliptical cross section, and the inner protrusion 13 with which the engagement protrusion 22 of the clip 2 engages is different along the minor axis direction thereof. There are two locations. The inner protrusion 13 has an inverse taper shape toward the tip of the cylindrical base portion 12, and further has a taper shape through a straight line portion. Reinforcing ribs 16 having a smaller amount of protrusion than the inner protrusions 13 are provided below the inner protrusions 13. Further, on the outer peripheral surface of the base portion 12, outer protrusions 14 engaging with the mounting holes 41 are provided at two different positions along the major axis direction thereof. The outer protrusion 14 is provided at a distance corresponding to the plate thickness of the trunk panel 4 from the lower surface of the collar portion 11, and is tapered toward the tip of the cylindrical base portion 12 and then gently reversed. It is tapered.

Next, a procedure for attaching the spoiler 3 to the trunk panel 4 using the cap 1 will be described. The clip 2 is embedded in the stay 32 of the spoiler 3 in advance by insert molding. The cap 1 is attached to the circular attachment hole 41 formed in the trunk panel 4. The outer protrusion 14 of the cap 1 contacts the hole edge 42 of the mounting hole 41. The outer peripheral surface 18 of the side surface of the tubular base 12 of the cap 1 on which the inner protrusion 13 is provided is elastically deformed in a direction of closing the gap 43 formed between the base 12 and the hole edge 42. This elastic deformation is an arc-shaped deformation along the hole edge 42 of the mounting hole 41. By smoothly elastically deforming the base portion 1 of the cap 1 through the gap 43, the cap 1 can be easily attached to the attachment hole 41. Next, the clip 2 attached to the spoiler 3 is inserted into the clip insertion portion 15 of the cap 1. The inner protrusion 13 of the cap 1 is elastically deformed outward. This elastic deformation is an arc-shaped deformation along the hole edge 42 of the mounting hole 41, but the gap 43 allows smooth elastic deformation. When the protruding end 26 of the barbed engagement protrusion 22 of the clip 2 passes through the straight portion of the inner protrusion 13 of the cap 1, the inner protrusion 13 elastically restores to its original position. The engaging projection 22 of the clip 2 is locked to the inner projection 13 of the cap 1 and cannot be easily removed. In this way, the spoiler 3 is temporarily fixed to the trunk panel 4. Furthermore, by screwing a bolt (not shown) into the nut 5 embedded in the spoiler 3, the spoiler 3 is fixed to the trunk panel 4 by the screw. Whether the cap 1 is attached to the trunk panel 4 or the clip 2 attached to the spoiler 3 is attached to the cap 1, a gap 43 allowing the elastic deformation of the cap 1 is formed between the cap 1 and the attachment hole edge. 42, the workability of attaching the spoiler 3 to the trunk panel 4 is improved.

[0011]
