DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hook mounting structure, which is an example of a vehicle interior component, will be described below with reference to the drawings.

In the drawings for explaining this embodiment, unless otherwise specified, the first direction, which is the axial direction of the insertion shaft of the hook, is indicated by an arrow X, and the second direction, which is perpendicular to the first direction X and orthogonal to each other, is indicated by The direction and the third direction are indicated by arrow Y and arrow Z.

As shown in FIGS. 1 and 2, the mounting structure 1 of the present embodiment is a structure related to mounting (or also referred to as "assembling") the hook 10, and generally includes the hook 10 as an interior component and the vehicle. The vehicle includes a deck trim 20 as an interior material constituting a luggage compartment, and a vehicle body panel 30.

The hook 10 has an insertion shaft portion 11 extending in the first direction X, a circular head portion 13 joined to the insertion shaft portion 11, and a disc-shaped base portion 14. The space between the head 13 and the pedestal 14 is typically used as a hooking area on which luggage, articles, and the like can be hung. If necessary, another hooking area may be added to the hook 10 to this hooking area.

The base portion 14 is configured as a flange portion facing the deck trim 20. This pedestal portion 14 is provided with a marking 16 that protrudes radially outward from a portion of its circumferential surface. This marking 16 is configured as a mark that allows the rotational position of the boss 15, which will be described later, to be indirectly confirmed when the hook 10 is attached. The material of the hook 10 is not particularly limited, but in consideration of moldability, weight reduction, etc., it is preferable to use a resin material as the material of the hook 10.

The deck trim 20 is provided with a base portion 21 having a mounting surface 21a for attaching the hook 10 to the pedestal portion 14. In the following description, of both surfaces of the base portion 21 of the deck trim 20 in the first direction X, the surface facing the vehicle interior (mounting seat surface 21a) will be referred to as the front surface, and the surface facing the vehicle body panel 30 will be referred to as the rear surface.

When attaching the hook 10, the pedestal section 14 is pressed against the mounting seat surface 21a, which is the surface of the base section 21. This base portion 21 is provided with one through hole 22 whose penetration direction is in the first direction X. This through hole 22 becomes a target hole when assembling the hook 10.

The vehicle body panel 30 is provided with one attachment hole 31 whose penetrating direction is the first direction X. This vehicle body panel 30 is disposed on the deck trim 20 with an opposing space S (see FIG. 3) in the first direction X. At this time, it is preferable that the deck trim 20 and the vehicle body panel 30 be arranged such that the positions of the through holes 22 and the mounting holes 31 approximately coincide with each other in the first direction X.

As shown in FIG. 3, a clip 12 as a fitting portion is provided at the tip of the insertion shaft portion 11 of the hook 10 on the axis L. As shown in FIG. The clip 12 is configured to be able to fit into the mounting hole 31 of the vehicle body panel 30 when the insertion shaft portion 11 is inserted into the through hole 22 of the deck trim 20. The clip 12 is made of an elastically deformable material (typically a resin material), and is configured to extend radially outward beyond the edge of the attachment hole 31. The clip 12 fits into the attachment hole 31 in a state in which it is elastically deformed so as to be crushed radially inward by press-fitting. As a result, a locking force is generated in the insertion shaft portion 11 inserted into the through hole 22 to lock it to the vehicle body panel 30. On the other hand, when the hook 10 is pulled by a load exceeding this locking force, the fitting between the clip 12 and the attachment hole 31 is released, and the insertion shaft portion 11 can be pulled out from the through hole 22.

The base portion 14 of the hook 10 is provided with a boss 15 as a rotation regulating portion. The boss 15 engages with the through hole 22 of the deck trim 20 when the insertion shaft 11 is inserted into the through hole 22 of the deck trim 20, and functions to restrict the rotation of the insertion shaft 11 around the axis.

When the boss 15 is viewed from the head 13 side, the operator cannot directly visually recognize the boss 15 because it is shielded by the pedestal section 14. Therefore, in this embodiment, the circumferential position of the boss 15 and the marking 16 (see FIGS. 1 to 3) on the pedestal portion 14 are made to match. This allows the operator to visually recognize the position of the boss 15 indirectly through the marking 16.

In the mounting structure of this embodiment, when the hook 10 is assembled, the hook 10 is pressed against the portion of the clip 12 fitted into the mounting hole 31 of the vehicle body panel 30 and the pedestal portion 14 of the deck trim 20. The boss 15 is supported at at least three locations by the base portion 21 and the support portion 24 of the deck trim 20 on which the boss 15 is supported.

The deck trim 20 includes a space filling part 23 that fills the opposing space S between the deck trim 20 and the vehicle body panel 30, and a support part 24 that supports the boss 15 of the hook 10 in the load action direction Y1 in which the hook 10 receives an external load F. have

As shown in FIGS. 3 to 5, the space filling portion 23 extends from the back surface of the base portion 21 toward the vehicle body panel 30. As shown in FIGS. The space filling portion 23 is a cylindrical surrounding rib provided on the back surface of the base portion 21 so as to surround the through hole 22, and is configured such that its extending end surface is in contact with the vehicle body panel 30.

By providing the space filling portion 23 in the deck trim 20, it is possible to prevent the mounting seat surface 21a of the base portion 21 from being deeply recessed toward the vehicle body panel 30 and to make the mounting seat surface 21a shallow. Therefore, the appearance of the design of the deck trim 20 can be improved, and the usability can be improved so that the user can easily use the hook 10. On the other hand, by bringing the extending end surface of the space filling portion 23 into contact with the vehicle body panel 30, the rigidity against the load that the deck trim 20 receives from the hook 10 can be increased.

In addition, regarding the position when providing the space filling part 23 on the back surface of the base part 21 of the deck trim 20, the space filling part 23 is positioned inside the outer shape of the pedestal part 14 when the hook 10 is assembled. It is preferable to set Thereby, even if a sink mark occurs on the surface of the base part 21 due to shrinkage during molding of the deck trim 20, this sink mark can be covered by the pedestal part 14 of the hook 10. Therefore, the appearance of the design surface of the deck trim 20 can be prevented from deteriorating due to the effects of sink marks.

As shown in FIG. 3, an external load F in the load acting direction Y1 acts on the head 13 of the hook 10 as a load when baggage, articles, etc. are hooked. At this time, the downward load acting on the boss 15 of the hook 10 can be received from below by the support portion 24. It is preferable that this support part 24 is constituted by a part of the space filling part 23. Thereby, the structure for supporting the boss 15 can be simplified.

As shown in FIG. 4, the through hole 22 of the deck trim 20 has a shape when viewed in the first direction X, in which a circular first hole 22a and a rectangular second hole 22b are connected to each other. It has a keyhole shape. This keyhole shape is determined based on the respective cross-sectional shapes of the insertion shaft portion 11 of the hook 10 and the boss 15. The first hole portion 22a is dimensioned such that its inner diameter exceeds the outer diameter of the insertion shaft portion 11 and does not inhibit insertion and removal operations of the insertion shaft portion 11. The second hole portion 22b is dimensioned so that its width in the third direction Z is slightly larger than the dimension of the boss 15 in the same direction. In the case of this embodiment, the width dimension of the second hole 22b in the third direction Z is smaller than the inner diameter of the first hole 22a.

Regarding the keyhole shape of the through hole 22, the shape of the first hole portion 22a does not need to be strictly circular, and may be substantially circular, such as a circle or an ellipse similar to a circle. . Similarly, the shape of the second hole 22b does not need to be a strict rectangle, and may just be a substantial rectangle, such as a rectangle or a rectangle with chamfered or rounded corners.

The boss 15 of the hook 10 is engaged with the deck trim 20 by being inserted into the second hole 22b of the through hole 22 with the insertion shaft 11 inserted into the first hole 22a of the through hole 22. It is configured to restrict rotation of the insertion shaft portion 11 in the direction around the axis. Thereby, the hook 10 can be prevented from rotating using the keyhole-shaped through hole 22 provided in the deck trim 20.

As shown in FIGS. 3 to 5, the deck trim 20 is provided with a recessed wall portion 25 formed by recessing the base portion 21 toward the back side. The recessed wall portion 25 is configured to have a substantially U-shape when viewed in the second direction Y. The accommodation space 25a defined by the recessed wall 25 is a space for accommodating the boss 15 inserted into the second hole 22b of the through hole 22. When the boss 15 is accommodated in the accommodation space 25a, movement in the direction around the axis of the insertion shaft portion 11 is restricted by the recessed wall portion 25.

Next, a procedure for assembling the hook 10 will be described with reference to FIGS. 6 to 8. In addition, in FIG. 6, for convenience of explanation, the deck trim 20 and the vehicle body panel 30 are shown in a separated state in which they are spaced apart in the first direction X.

As shown in FIG. 6, when assembling the hook 10 to the deck trim 20 arranged such that the second hole 22b extends downward from the first hole 22a in the through hole 22, the operator first attaches the hook 10 to the deck trim 20. Grasp the head 13 with your fingers so that the marking 16 faces downward. Then, aiming at the through hole 22 of the deck trim 20, the insertion shaft portion 11 of the hook 10 is inserted into this through hole 22.

As shown in FIG. 7, when the position of the boss 15 of the hook 10 is aligned with the position of the second hole part 22b of the through hole 22, the hook is held until the clip 12 fits into the mounting hole 31 of the vehicle body panel 30. It becomes possible to continue inserting the insertion shaft portion 11 of 10. At the normal position P1 of the hook 10, the insertion shaft portion 11 is locked to the vehicle body panel 30 by the clip 12 fitting into the attachment hole 31. In this normal position P1, the boss 15 of the hook 10 is inserted into the second hole 22b of the through hole 22, and its rotation in the direction D around the axis is restricted by the recessed wall 25. At this time, the operator can easily determine whether the hook 10 has been improperly assembled by visually checking the position of the boss 15 indirectly through the marking 16.

On the other hand, when inserting the insertion shaft portion 11 of the hook 10 into the through hole 22, the position of the boss 15 shifts from the position of the second hole portion 22b of the through hole 22 and interferes with the surface of the base portion 21. is assumed. At this time, the hook 10 is in an incomplete position P2 as shown in FIG. It cannot be fitted to the Therefore, when the hook 10 is in the incomplete position P2, the hook 10 is moved in the assembly adjustment direction (in FIG. 8, the axial direction D) until the boss 15 is inserted into the second hole 22b of the through hole 22. Rotate in a certain clockwise direction D1). Thereby, the hook 10 can be set to the normal position P1 (see FIG. 7).

According to the above embodiment, the following effects can be obtained.

In the mounting structure 1 described above, when the hook 10 is mounted, the insertion shaft portion 11 thereof is inserted into the through hole 22 of the deck trim 20. At this time, the hook 10 is attached by fitting the clip 12 into the attachment hole 31 of the vehicle body panel 30, which is arranged on the deck trim 20 across the opposing space S. In addition, the hook 10 restricts rotation of the insertion shaft 11 in the axial direction D by engaging the boss 15 with the second hole 22b of the through hole 22 when the insertion shaft 11 is inserted into the through hole 22. be done.

According to this mounting structure 1, by providing the opposing space S between the deck trim 20 and the vehicle body panel 30, the mounting surface 21a for mounting the hook 10 on the deck trim 20 can be easily recessed without having to be deeply recessed. 10 installations are possible. Therefore, the shape of the mounting seat surface 21a (design surface) of the base portion 21 of the deck trim 20 can be freely designed without degrading its appearance.

Therefore, according to the embodiment described above, it is possible to increase the degree of freedom in designing the deck trim 20 to which the hook 10 is attached.

According to the above-described mounting structure 1, the space filling portion 23 that fills the opposing space S between the deck trim 20 and the vehicle body panel 30 is configured using the deck trim 20. Therefore, there is no need to add new parts for the space filling section 23 that maintains the facing space S, which is effective in reducing the number of parts.

According to the above-described mounting structure 1, the hook 10 is supported at at least three locations: the mounting hole 31 of the vehicle body panel 30, the base portion 21 of the deck trim 20, and the support portion 24 of the deck trim 20. Can be done. Therefore, the load acting on the hook 10 can be distributed to the deck trim 20 and the vehicle body panel 30 in a well-balanced manner, which is effective in stabilizing the attachment state of the hook 10.

According to the above-mentioned mounting structure 1, the through hole 22 of the deck trim 20 has a keyhole shape having the first hole 22a and the second hole 22b, so that the insertion shaft of the hook 10 can be inserted easily. Only one hole is required. Therefore, when the operator inserts the insertion shaft portion 11 of the hook 10 into the through hole 22, it becomes easier for the operator to aim at the through hole 22. For example, compared to the case where a plurality of aiming holes are employed, the ease of assembling the hook 10 is improved, so the time required for assembling the hook 10 can be shortened. Furthermore, by limiting the number of attachment holes 31 provided in the vehicle body panel 30 to one, it is possible to prevent the number of attachment holes provided in the vehicle body panel 30 from increasing more than necessary. This improves the moldability of the vehicle body panel 30.

The present invention is not limited to the above-described embodiments, and various applications and modifications can be made without departing from the purpose of the present invention. For example, the following embodiments that apply the above-described embodiments can also be implemented.

In the above-described embodiment, a case where the deck trim 20 is provided with the space filling part 23 that fills the facing space S between the deck trim 20 and the vehicle body panel 30 is illustrated, but instead of this, a space filling part 23 corresponding to the space filling part 23 is provided. Elements can also be provided on the hook 10 or on both the hook 10 and the deck trim 20.

In the above-described embodiment, the shape of the through hole 22 of the deck trim 20 is exemplified as a keyhole shape in which the circular first hole portion and the rectangular second hole portion are connected to each other. The shape of the hole 22 is not limited to this, and can be changed as appropriate based on the respective cross-sectional shapes of the insertion shaft portion 11 of the hook 10 and the boss 15.

In the above-described embodiment, the mounting structure 1 for the hook 10, which is one of the interior components, is illustrated, but the mounting structure 1 may be applied to a mounting structure for a different type of interior component from the hook 10.
