Description

[Technical field]

[0001] The present invention relates to a clip holding structure, and more particularly to a structure for holding a clip in a clip mounting seat provided on an attachment member. [Background technology]

[0002] Generally, when a member to be assembled, such as a door trim, is to be assembled to a member to be assembled, such as a body panel of an automobile, the assembly is performed via a clip. Specifically, one end of the clip is attached in advance to a clip mounting seat provided on the door trim, and in this state, the other end of the clip is pushed into a fitting hole provided on the body panel, and the clip is fitted into the fitting hole, thereby assembling the door trim to the body panel.

[0003] In this case, since the door trim or the like to be assembled is large, it is necessary to use multiple clips for assembly. Therefore, in such a case, the door trim or the like is provided with clip mounting seats in multiple locations, and the vehicle body panel or the like is provided with fitting holes in multiple locations to accommodate the multiple clips.

[0004] When each of the multiple clips is pre-attached to the corresponding clip mounting seat, each of the multiple clips needs to be held in the corresponding clip mounting seat so that each of the multiple clips does not shift its position due to, for example, the clip's own weight or fall off from the corresponding clip mounting seat.

[0005] In response to such demands, as seen in Patent Document 1, a structure is provided in which a locking hole is provided in the clip mounting seat, a locking protrusion is provided on the clip, and the locking hole is engaged with the locking protrusion to hold the clip in the clip mounting seat so that the clip does not fall off from the clip mounting seat.

[0006] However, when each of the multiple clips is held in the corresponding clip mounting seat as described above and then each of the multiple clips is fitted into the corresponding fitting hole, there are cases, though not all combinations of clips and fitting holes, where the position of the axial center of the clip does not match the position of the axial center of the corresponding fitting hole due to vibration or the like when transporting an assembly member with the clips previously attached to the clip mounting seat. In combinations of clips and fitting holes where the positions of the axial centers do not match, it is not possible to fit the clip into the fitting hole, and as a result, it is not possible to assemble the door trim or the like to the vehicle body panel or the like.

[0008] In view of the above circumstances, the problem that the present invention aims to solve is to provide a structure for holding a clip in a clip mounting seat provided on a door trim or the like, so that a clip that is pre-attached to the clip mounting seat does not fall off from the clip mounting seat, and the door trim or the like can be easily assembled to a vehicle body panel or the like. [Means for solving the problem]

[0009] The present invention has been made to solve these problems, and in one embodiment of the present invention, a structure for holding a clip on a clip attachment seat provided on an assembly member comprises: a clip having a head on one end side of a shaft, a leg on the other end side of the shaft, and a flange between the head and leg of the shaft, the flange having an engagement portion on a surface on the head side, and the clip attachment seat having the engagement portion, an attachment hole having a diameter smaller than that of the head and flange, and an opening leading to the attachment hole, and by inserting the shaft between the head and flange through the opening from the radial direction into the attachment hole, the attachment hole is positioned between the head and flange, and the clip is attached to the clip attachment seat. When the clip is attached to the clip mounting seat, the engaging portion of the clip engages with the engaging portion of the clip mounting seat, regulating the position of the axial center of the clip by the engagement, and when, with the clip attached to the clip mounting seat, the legs are inserted into and engaged with a fitting hole of a member to be attached, if the position of the axial center of the clip differs from that of the axial center of the fitting hole, when the legs are guided toward the axial center of the fitting hole, the engagement between the engaging portion of the clip and the engaging portion of the clip mounting seat is released so that the clip can move so that the position of the axial center of the clip approaches that of the axial center of the fitting hole.

[0010] In another embodiment, the structure for holding the clip in the clip mounting seat provided on the mounting member may be such that the engagement portion of the clip mounting seat is the edge of the mounting hole, or the engagement portion of the clip is a protrusion.

[0011] In addition, in another embodiment, the structure for holding the clip in the clip mounting seat provided on the mounting member may be such that the engagement portion of the clip mounting seat is a groove, or the engagement portion of the clip is a protrusion.

[0012] In addition, in another embodiment, the structure for holding the clip on the clip mounting seat provided on the mounting member may be such that the engagement portion of the clip mounting seat is a protrusion, or the engagement portion of the clip is a protrusion.

[0013] In addition, in another embodiment, the structure for holding the clip in the clip mounting seat provided on the mounting member may have multiple protrusions on the clip, and at least two of the multiple protrusions may engage with the engagement portion of the clip mounting seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, the structures of the clip 10 and the clip mounting seat 22 according to the embodiment of the present invention will be described with reference to the drawings.

[0017] FIG. 1 shows a perspective view of a clip 10 and an attachment member 20 according to a first embodiment of the present invention. The clip 10 is made of, for example, resin. The clip 10 includes a head 11, a shaft 12, a flange 13, and a leg 15. The head 11 is located at one end of the shaft 12. The leg 15 is located at the other end of the shaft 12. The leg 15 includes a protrusion that can be fitted into a fitting hole 33 of an attachment member 30, which will be described later. The shape of the protrusion is not limited to a protrusion, and any shape can be used as long as the protrusion can be fitted into the fitting hole 33 of the attachment member 30. The flange 13 is located between the head 11 and the leg 15 on the shaft 12, and is preferably closer to the head 11. The diameter of the flange 13 is set to be larger than the diameter of the head 11. The flange 13 has a substantially horizontal surface on the inner diameter side and an inclined surface on the outer diameter side, with a certain position as a boundary in the radial direction. The flange 13 has engagement portions 14 (14a, 14b, 14c, 14d) on the surface on the head 11 side, which is an approximately horizontal plane on the inner diameter side. The engagement portions 14 may be protrusions. The protrusions may be hemispherical. In this embodiment, the engagement portions 14 have four protrusions that are approximately equally spaced when viewed in the +Z direction, but this is not limited to this. It is preferable to provide at least three protrusions that are approximately equally spaced so that there are no restrictions on the mounting direction of the clip 10 when mounting the clip 10 to the clip mounting base 22, which will be described later.

[0018] The mounting member 20 is, for example, a door trim to be mounted on a body panel of an automobile. The mounting member 20 includes a base 21 and a clip mounting seat 22. The clip mounting seat 22 is provided on the base 21, and three of the four side surfaces of the clip mounting seat 22 extend in the +Z direction, and the remaining side surface is open. The clip mounting seat 22 has a surface facing the base 21 from the three side surfaces. The clip mounting seat 22 includes a mounting hole 23, an opening 24, and an engagement portion 25 on the surface facing the base 21. The mounting hole 23 is a hole having a diameter smaller than the diameters of the head 11 and the flange 13 of the clip 10. The opening 24 communicates with the mounting hole 23 and communicates with one open side surface of the clip mounting seat 22. In this embodiment, the engagement portion 25 is the edge of the mounting hole 23.

[0019] As shown by the dashed arrow in Figure 1, clip 10 is attached to clip mounting base 22 by inserting shaft portion 12 between head 11 and flange 13 of clip 10 in the +Y direction through opening 24 from one open side of clip mounting base 22 into mounting hole 23.

[0020] FIG. 2 shows a perspective view of the state in which the clip 10 is attached to the clip mounting seat 22 of the first embodiment of the present invention. FIG. 3 shows a cross-sectional view taken along line AA in FIG. 2. Furthermore, FIG. 4 shows a cross-sectional view taken along line BB in FIG. 2. As can be seen from FIGS. 3 and 4, the four projections 14a, 14b, 14c, and 14d of the engagement portion 14 are located inside the edge of the mounting hole 23, and three of the projections 14a, 14c, and 14d are engaged with the edge of the mounting hole 23, which is the engagement portion 25 of the clip mounting seat 22. This engagement restricts the position of the axial center of the clip 10 to coincide with the position of the center of the mounting hole 23 on the Z axis, and the clip 10 is held by the clip mounting seat 22 by restricting the position of the axial center of the clip 10. Here, it is preferable that the projections 14a, 14b, 14c, and 14d are arranged on the surface of the flange 13 at approximately equal intervals, since the clip 10 is more stably held by the clip mounting seat 22. Furthermore, for clip 10 to be held in clip mounting seat 22, it is sufficient that at least two protrusions engage with the edge, but when clip 10 is mounted to clip mounting seat 22, protrusion 14b may be located at a position where there is an edgeless opening 24, as shown in Fig. 4, and the protrusion may not engage with the edge. Therefore, taking such a case into consideration, if at least three protrusions are located at approximately equal intervals on the surface of flange 13 as described above, at least two protrusions can engage with the edge, which is engagement portion 25.

[0021] 5 to 7 are diagrams showing the initial, intermediate and final states, respectively, of clip 10 attached to clip mounting base 22 of the first embodiment of the present invention, when clip 10 is pushed in the +Z direction and leg 15 is inserted and fitted into fitting hole 33 of mounted member 30 via leading clip 31. First, referring to Fig. 5, it can be seen that the position of the axial center of clip 10 (line CC) and the position of the axial center of fitting hole 33 of mounted member 30 (line DD) are different.

[0022] 6 is a diagram showing a state in which the clip 10 is further pushed in the +Z direction from the state shown in FIG. 5. Referring to FIG. 6, the leg 15 of the clip 10 is in contact with the inner surface 32 of the leading clip 31 attached to the fitting hole 33. When the clip 10 is further pushed in the +Z direction and a load is applied to the clip 10 while in contact with the inner surface 32, the leg 15 in contact receives a load from the inclined inner surface 32 of the leading clip 31 in the -X direction along the line DD, which is the axial center of the fitting hole 33, and is guided in the -X direction. As the leg 15 is guided in the -X direction, a load is applied to the clip 10 in the -X direction. When a load is applied to the clip 10 in the -X direction, a load is applied between the protrusion 14a and the edge which is the engagement portion 25, and as can be seen from FIG. 6, the flange 13 bends in the +Z direction, the protrusion 14a overcomes the edge, and the engagement between the protrusion 14a which is the engagement portion 14 on the flange 13 surface and the edge of the mounting hole 23 which is the engagement portion 25 is released, and the clip 10 moves in the -X direction. In FIG. 5, the width X1 and the width X2 of the mounting hole 23 are the same, but as the clip 10 moves in the -X direction, the width X2 of the mounting hole 23 becomes smaller than the width X1 in FIG. 6. Also, as the clip 10 moves in the -X direction, the difference between the CC line and the DD line in FIG. 5 becomes smaller in FIG. 6, and it can be seen that the CC line and the DD line approach each other. Note that if the flange 13 is easily bent, the engagement between the protrusion 14a which is the engagement portion 14 on the flange 13 surface and the edge of the mounting hole 23 which is the engagement portion 25 is easily released. Therefore, it is preferable that the flange 13 is designed to be thin so that it can be easily bent.

[0023] Finally, Fig. 7 shows a state in which the clip 10 is further pushed in the +Z direction from the state in Fig. 6, and the leg 15 is fitted into the fitting hole 33 of the member to be assembled 30 via the leading clip 31, more specifically, the leg 15 is fitted into the fitting hole 33 of the member to be assembled 30 by fitting the leg 15 into the flexible elastic piece provided on the leading clip 31 of the member to be assembled 30. Referring to Fig. 7, as described above, the leg 15 in contact with the inclined inner surface 32 of the leading clip 31 is further loaded in the -X direction and guided in the -X direction, and as a result, the clip 10 moves further in the -X direction, so that the width X2 of the mounting hole 23 becomes smaller compared to Fig. 6. Also, in Fig. 7, compared to Fig. 6, it can be seen that the leg 15 is fitted into the flexible elastic piece provided on the leading clip 31 of the member to be assembled 30, and the CC line and the DD line become closer to each other, and as a result, the CC line and the DD line overlap each other.

[0024] In this way, when the position of the axial center of the clip 10 differs from the position of the axial center of the fitting hole 33, the engagement between the clip 10 and the clip mounting seat 22 is released, thereby making it possible to easily assemble the mounting member 20 to the mounted member 30.

[0025] As described above, the case where the position of the axial center of the clip 10 is displaced in the +X direction from the position of the axial center of the fitting hole 33 has been shown, but the positional displacement is not limited to the +X direction, and positional displacement in all directions in the XY plane can be corrected by releasing the above-mentioned engagement so that the clip 10 can move. In addition, since a load is locally applied to the projections 14a, 14b, 14c, and 14d that are the engagement portion 14 on the flange 13 surface, the engagement with the engagement portion 25 is released with a relatively low load. As shown in Figs. 5 to 7, the clip 10 may be fitted into the fitting hole 33 via the leading clip 31, or, for example, the clip 10 may be directly fitted into the fitting hole 33 without the leading clip 31.

[0026] Fig. 8 shows a perspective view of a clip 10 and an attachment member 20 according to a second embodiment of the present invention. Fig. 9 shows a perspective view of a state in which a clip 10 is attached to a clip attachment seat 22 according to the second embodiment of the present invention. Fig. 10 shows a cross-sectional view taken along line AA in Fig. 9. Furthermore, Fig. 11 shows a cross-sectional view taken along line BB in Fig. 9. In this embodiment, components similar to those in the first embodiment are given the same reference numerals as in the first embodiment, and detailed description thereof will be omitted.

[0027] The engaging portion 14 of the clip 10 of this embodiment has four protrusions on the surface of the flange 13 as in the first embodiment, but as can be seen by comparing FIG. 11 with FIG. 4, the protrusions of this embodiment are provided on the outer diameter side of the surface of the flange 13 compared to the protrusions of the first embodiment. As can be seen by referring to FIGS. 10 and 11, the engaging portion 25 of the clip mounting base 22 of this embodiment is a groove that is concentric with the mounting hole 23 and has a larger diameter than the mounting hole 23, and is provided in an arc shape. The cross-sectional shape of the groove is semicircular. Note that the cross-sectional shape of the groove is not limited to this, and may be, for example, a semi-elliptical shape or a triangular shape. In the first embodiment, the protrusions and the edges are engaged, whereas in this embodiment, the protrusions and the grooves are engaged, and the same effect as in the first embodiment is achieved in this embodiment. The depth of the groove may be set shallower than the protrusions so that the protrusions do not fit into the grooves, so that the engagement can be easily released when the clip 10 is fitted into the fitting hole 33 of the mounting member 30.

[0028] Fig. 12 shows a perspective view of a clip 10 and an attachment member 20 according to a third embodiment of the present invention. Fig. 13 shows a perspective view of a state in which a clip 10 is attached to a clip attachment seat 22 according to the third embodiment of the present invention. Fig. 14 shows a cross-sectional view taken along line AA in Fig. 13. Furthermore, Fig. 15 shows a cross-sectional view taken along line BB in Fig. 13. In this embodiment, components similar to those in the first embodiment are given the same reference numerals as in the first embodiment, and detailed description thereof will be omitted.

[0029] The engaging portion 14 of the clip 10 of this embodiment has four protrusions on the surface of the flange 13 as in the first embodiment, but as can be seen by comparing Fig. 15 with Fig. 4, the protrusions in this embodiment are provided on the outer diameter side of the surface of the flange 13 compared to the first embodiment. As can be seen by referring to Figs. 14 and 15, the engaging portion 25 of the clip mounting base 22 of this embodiment is an arc-shaped protrusion that is concentric with the mounting hole 23 and has a larger diameter than the mounting hole 23. The cross-sectional shape of the protrusion is semicircular. However, the cross-sectional shape of the protrusion is not limited to this and may be, for example, semi-elliptical or triangular. Regarding the arrangement of the engaging portion 14 of the clip 10 and the engaging portion 25 of the clip mounting seat 22, in this embodiment, as can be seen from FIG. 15, the arc-shaped protrusion, which is the engaging portion 25 provided on the clip mounting seat 22, is provided on the outer diameter side of the protrusions 14a, 14b, 14c, and 14d, which are the engaging portion 14 provided on the flange 13 surface of the clip 10, and the protrusion on the flange 13 surface of the clip 10 on the inner diameter side engages with the arc-shaped protrusion of the clip mounting seat 22 on the outer diameter side. Note that, while the protrusion and the edge are engaged in the first embodiment, the protrusion and the protrusion are engaged in the present embodiment, but the same effect as the first embodiment is achieved in this embodiment. The depth of the protrusion of the clip mounting seat 22 may be set shallower than the protrusion on the flange 13 surface so that the engagement can be easily released when the clip 10 is fitted into the fitting hole 33 of the mounted member 30 by the protrusion on the flange 13 surface passing over the protrusion on the clip mounting seat 22.

[0030] Fig. 16 shows a perspective view of a clip 10 and an attachment member 20 according to a modified example of the third embodiment of the present invention. Fig. 17 shows a perspective view of a state in which a clip 10 is attached to a clip attachment seat 22 according to a modified example of the third embodiment of the present invention. Fig. 18 shows a cross-sectional view taken along line AA in Fig. 17. Fig. 18 also shows a cross-sectional view taken along line BB in Fig. 17. In this modified example, components similar to those in the first embodiment are given the same reference numerals as in the first embodiment, and detailed descriptions thereof will be omitted.

[0031] The engaging portion 14 of the clip 10 of this modification has four protrusions on the flange 13 surface as in the third embodiment, but as can be seen by comparing FIG. 19 with FIG. 15, the protrusions on the flange 13 surface of this modification are provided on the outer diameter side of the flange 13 surface compared to the third embodiment. Also, as can be seen by comparing FIG. 19 with FIG. 15, while four protrusions (14a, 14b, 14c, 14d) are provided in the third embodiment, six protrusions (14a, 14b, 14c, 14d, 14e, 14f) are provided in this modification. As can be seen by referring to FIG. 18 and FIG. 19, the engaging portion 25 of the clip mounting base 22 of this modification is a protrusion provided in an arc shape that is concentric with the mounting hole 23 and has a larger diameter than the mounting hole 23. The cross-sectional shape of the protrusion is semicircular. Note that the cross-sectional shape of the protrusion is not limited to this, and may be, for example, a semi-elliptical shape or a triangular shape. Regarding the arrangement of the engagement portion 14 of the clip 10 and the engagement portion 25 of the clip mounting base 22, in this modified example, as can be seen by referring to Figure 19, unlike the third embodiment, the arc-shaped protrusion which is the engagement portion 25 provided on the clip mounting base 22 is provided on the inner diameter side of the protrusions 14a, 14b, 14c, 14d, 14e, and 14f which are the engagement portion 14 provided on the flange 13 surface of the clip 10, and the protrusion on the flange 13 surface of the clip 10 on the outer diameter side engages with the arc-shaped protrusion of the clip mounting base 22 on the inner diameter side.

[0032] When attaching the clip 10 to the clip mounting seat 22, as described above, the protrusions 14 on the flange 13 surface of the clip 10 are engaged with the engaging portions 25 of the clip mounting seat 22, and at this time, due to the difference in arrangement of the protrusions 14 of the clip 10 and the engaging portions 25 of the clip mounting seat 22 between this modified example and the third embodiment as described above, this modified example may be superior to the third embodiment. That is, when attaching the clip 10 to the clip mounting seat 22, in the third embodiment, in order to engage the protrusions 14 of the clip 10 with the protrusions that are the engaging portions 25 of the clip mounting seat 22, the protrusions 14 need to climb over the engaging portions 25 in at least three places. 19, for example, when clip 10 is inserted into clip mounting seat 22 in a direction of 45° (lower left direction as viewed in the drawing) toward the +Y direction (downward direction as viewed in the drawing) with respect to the +X direction (left direction as viewed in the drawing), in order to engage protrusion 14 of clip 10 with protrusion that is engaging portion 25 of clip mounting seat 22, there are only two locations where protrusion 14 of clip 10 needs to climb over protrusion that is engaging portion 25. Therefore, this modification is advantageous over the third embodiment in that there are cases where the number of protrusions 14 of clip 10 that need to climb over engaging portion 25 of clip mounting seat 22 is reduced.

[0033] In the first embodiment, the protrusions and edges are engaged, whereas in this modified example, the protrusions are engaged with each other, but this modified example provides the same effects as the first embodiment. The depth of the protrusions of the clip mounting seat 22 may be set shallower than the protrusions of the flange 13 surface so that the engagement can be easily released when the clip 10 is fitted into the fitting hole 33 of the mounted member 30.

[0034] As a further modified example, an arc-shaped protrusion, which is the engagement portion 25 provided on the clip mounting base 22, may be provided double on the inner diameter side and outer diameter side with respect to the protrusion 14 on the flange 13 surface of the clip 10, so that the protrusion on the flange 13 surface of the clip 10 engages with the arc-shaped protrusions on the inner diameter side and outer diameter side of the clip mounting base 22.

[0035] The first to third embodiments of the present invention have been described above with reference to the figures. However, the structure of the clip and the clip mounting seat is not limited to the specific structure described and can be modified as appropriate, as long as the clip and the clip mounting seat are configured so that the engagement between the clip and the clip mounting seat is released when the position of the axial center of the clip differs from the position of the axial center of the fitting hole.

[0036] Furthermore, although the present invention has been described using the first to third embodiments, the application of the present invention is not limited to application to, for example, vehicle body panels, but can be applied to various panels, and can be applied as appropriate within the scope of the technical concept of the invention.
