Description

  The present invention relates to a clip mounting seat for interior parts or exterior parts having a clip mounting surface on which a clip can be mounted.

  2. Description of the Related Art Conventionally, when attaching automobile interior parts (for example, an instrument panel, a door trim, etc.) to a vehicle body panel, for example, a clip is used. When the clip is used in this way, a clip mounting seat having a clip mounting surface that can be mounted by sandwiching the upper and lower flanges of the clip is formed on the inner surface of the interior part. Here, the following Patent Document 1 discloses a clip mounting seat 203 in which convex portions 222a and 222a are formed on a clip mounting surface 222 as shown in FIG. When the convex portions 222a and 222a are formed in this manner, even if an external force acts on the clip mounting surface 222 in the removal direction with respect to the clip 201 in the mounted state, The part 214a interferes. Therefore, since the convex portions 222a and 222a fulfill the function of preventing the dropping, the clip 201 in the mounted state can be prevented from dropping from the clip mounting surface 222.

Japanese Patent Application No. 2000-192918

  However, in the technique of Patent Document 1 described above, if the external force acting in the pulling direction on the clip 201 in the mounted state is large, the protrusions 222a and 222a formed on the clip mounting surface 222 may be scraped. If cut in this way, the clip 201 may fall off the clip mounting surface 222 because the upper flange portion 214a of the clip 201 gets over the cut protrusions 222a and 222a. If it falls off in this way, it is necessary to mount the clip 201 on the clip mounting surface 222 again. However, since the protrusions 222a and 222a have already been scraped, there has been a problem that the function of preventing the clip 201 that has been reattached from falling off.

  The present invention is intended to solve such problems, and its purpose is to provide a drop-off prevention function capable of preventing the attached clip from falling off the clip attachment surface, and preventing the attached clip from falling off. An object of the present invention is to provide a clip mounting seat for an interior part that can prevent a drop-off preventing function from being lowered when a clip is remounted even if the clip is dropped against the function.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 has a clip mounting surface formed through a step with respect to the interior part or the exterior part, and the step is formed from a peripheral wall that is partially opened. The clip mounting surface has a mounting hole that can mount the neck of the clip to be mounted, a guide groove that can guide the neck of the clip from the edge on the open side to the mounting hole, and a function to prevent the clip from being dropped And a clip mounting seat for an interior part or an exterior part provided with the anti-drop-off function, wherein the guide groove is extended from the open side edge on the open side edge of the clip mounting surface. A pair of flexure pieces formed in the manner described above and a warp formed on the guide groove side edge of the pair of flexure pieces so as to prevent the attached clip from falling off. It is a configuration characterized by.
According to this configuration, as in the prior art, even when an external force acts on the clip mounted surface on the clip mounted surface in the pulling direction, the mounted clip is prevented from falling off the clip mounted surface. it can. Note that if the external force acting in the pulling direction on the clip in the attached state is large, the pair of flexure pieces and both sides will bend in the reverse direction of the procedure for attaching the clip, so the clip is a clip on the clip mounting seat. It will fall off the mounting surface. At this time, the member (a pair of flexure pieces and both sides) corresponding to the convex portion of the prior art is not scraped. Therefore, even if the clip is remounted, the function of preventing the clip that has been remounted does not drop.

The invention according to claim 2 is the clip mounting seat for the interior part or exterior part according to claim 1, wherein the edge on the mounting hole side in the plan view is opposite to the edge of the guide groove. The configuration is characterized in that it is set to form an acute angle.
According to this configuration, when both warpages act as a drop-off prevention function, for example, in plan view, the edge on the mounting hole side in warpage is set to form an obtuse angle with respect to the edge of the guide groove In comparison, this drop-off prevention function can be strengthened.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Example 1
First, Example 1 of the present invention will be described with reference to FIGS. First, the clip 1 and the interior part 2 according to the first embodiment will be described individually.

  First, the clip 1 will be described. The clip 1 is a well-known one, and includes a circular substrate body 10 forming a base thereof, an anchor body 12 protruding from the upper surface of the substrate body 10, and a mounting body 14 protruding from the lower surface of the substrate body 10. Therefore, it is integrally formed of a synthetic resin having rigidity. On the outer periphery of the substrate body 10, a stabilizer 10 a that protrudes upward in a dish shape is formed.

  The anchor body 12 is composed of an inflatable body that can be inserted into a mounting hole (both not shown) of the vehicle body panel. In addition, a plurality of (for example, four) elastic claws 12 a are formed on the outer periphery of the anchor body 12. Thereby, the anchor body 12 inserted into the mounting hole of the vehicle body panel can be engaged.

  The mounting body 14 includes a pair of upper and lower collars (upper collar part 14a and lower collar part 14b) formed so as to be able to sandwich the front and back of the clip mounting surface 22 of the clip mounting seat 3 to be described later, and these upper and lower collar parts. It is comprised from the neck part 14c formed in the shape of a neck which bridges between 14a and 14b. The clip 1 is configured in this way.

  Next, the interior part 2 will be described. The clip 1 is mounted on the inner surface (anti-design surface) of the interior part (for example, instrument panel, door trim, etc.) by the upper and lower flange portions 14a and 14b of the clip 1 sandwiching the front and back of the clip mounting surface 22 A clip mounting seat 3 is formed. The clip mounting seat 3 will be described in detail. As shown in FIGS. 1 to 4, the clip mounting seat 3 is formed so as to block the peripheral wall 20 protruding from the interior part 2 and the upper side of the peripheral wall 20. The clip mounting surface 22 is integrated with the interior part 2.

  A part of the peripheral wall 20 is opened as is apparent from FIG. That is, an opening 20a is formed in a part of the peripheral wall 20 (a part on the guide groove 26 side described later). On the other hand, the clip mounting surface 22 is formed with a mounting hole 24 in which the neck 14c of the clip 1 can be mounted, and a guide groove 26 capable of guiding the neck 14c of the clip 1 from the edge on the opening 20a side to the mounting hole 24. ing.

  A pair of flexure pieces 28 projecting from the edge on the opening 20a side are formed on the edge on the opening 20a side of the clip mounting surface 22 so as to extend the guide groove 26. The pair of bending pieces 28 are formed in a thin shape so as to be easily bent when receiving an external force (see FIG. 4). The pair of bending pieces 28 are formed in a rising shape (facing diagonally upward) so that the warps 30 and 30 that prevent the clip 1 from falling off face each other.

  This warpage 30 corresponds to a “stopper” that prevents the clip 1 from falling off. Both the warps 30 are also formed in a thin shape so as to be easily bent when receiving an external force (see FIG. 3). 2, in the plan view of the clip mounting seat 3, the edge 30a on the mounting hole 24 side in the warp 30 is a first angle α (acute angle with respect to the edge 26a of the guide groove 26, for example, , About 60 °).

  Similarly, in the plan view of the clip mounting seat 3, the edge 30 b opposite to the edge 30 a on the side of the mounting hole 24 in the warp 30 (the edge on the tip side of the guide groove 26) is also the edge 26 a of the guide groove 26. On the other hand, the second angle β (acute angle, for example, about 45 °) is set. This makes it easier to guide the neck 14 c of the clip 1 into the guide groove 26 when the clip 1 is attached to the clip mounting seat 3. The interior part 2 is configured in this way.

  Next, a procedure for mounting the clip 1 on the clip mounting surface 22 of the clip mounting seat 3 of the interior part 2 will be described with reference to FIGS. First, hold the anchor body 12 of the clip 1 with a finger (not shown) so that the front and back of the clip mounting surface 22 are sandwiched between the upper and lower flange portions 14a and 14b of the clip 1 from the state shown in FIGS. The neck portion 14c of the clip 1 is guided toward the guide groove 26 of the clip mounting seat 3.

  Then, as shown in FIG. 6, the upper flange portion 14 a of the clip 1 pushes the opposite side 30, so that the pair of bending pieces 28 are bent downward. When the neck portion 14c of the clip 1 is pushed toward the mounting hole 24 of the clip mounting seat 3 from this state, the neck portion 14c of the clip 1 pushes the opposite side 30 as shown in FIG. The bending piece 28 is bent downward (while greatly bending downward), and the opposite sides 30 are also bent in a direction away from each other.

  When the two warps 30 are bent in this way, the pair of flexure pieces 28 are also greatly bent, so that an operation load necessary to bend the both warps 30 can be suppressed. From this state, when the neck portion 14c of the clip 1 is pushed further toward the mounting hole 24 of the clip mounting seat 3, the neck portion 14c of the clip 1 gets over both sides 30 as shown in FIG. The warp 30 is returned to the state before being pushed by the neck portion 14c.

  From this state, when the neck portion 14c of the clip 1 is pushed further toward the mounting hole 24 of the clip mounting seat 3, the upper collar portion 14a of the clip 1 gets over both sides 30 as shown in FIG. The pair of bending pieces 28 is returned to the state before the bending. From this state, when the neck portion 14c of the clip 1 is further pushed toward the mounting hole 24 of the clip mounting seat 3, the neck portion 14c of the clip 1 enters the mounting hole 24 of the clip mounting surface 22 as shown in FIG. Installed. That is, the clip 1 is mounted on the clip mounting surface 22 of the clip mounting seat 3.

  Finally, a case where an external force is applied to the clip 1 in the attached state in the pulling direction is described. When this external force acts on the clip 1, the neck portion 14 c of the clip 1 moves from the mounting hole 24 of the clip mounting surface 22 to the guide groove 26. Then, the upper collar portion 14 a of the clip 1 comes into contact with the warpage 30 of the pair of bending pieces 28 on the clip mounting surface 22. As a result, further movement of the clip 1 is restricted. In other words, the opposite side 30 functions as a drop-off preventing function. Therefore, even when an external force is applied to the clip 1 in the mounted state in the pulling direction, the clip 1 in the mounted state drops off from the clip mounting surface 22 of the clip mounting seat 3 as in the prior art. Can be prevented.

  Of course, there is a limit to this drop-off prevention function. For this reason, when the external force acting in the pulling direction on the clip 1 in the mounted state is large, the pair of bending pieces 28 and the both warps 30 are bent in the reverse direction to the description of the procedure for mounting the clip 1 described above. It goes without saying that 1 falls off the clip mounting surface 22 of the clip mounting seat 3.

  The clip mounting seat 3 of the interior part 2 according to the first embodiment of the present invention is configured as described above. According to this configuration, even when an external force acts on the clip 1 in the attached state on the clip attachment surface 22 in the pulling direction as in the prior art, the clip 1 in the attachment state falls off the clip attachment surface 22. Can be prevented. Note that if the external force acting in the pulling direction on the clip 1 in the mounted state is large, the pair of bending pieces 28 and the both warps 30 are bent in the reverse direction to the description of the procedure for mounting the clip 1 described above. 1 falls off the clip mounting surface 22 of the clip mounting seat 3. At this time, the member (the pair of bending pieces 28 and both warps 30) corresponding to the convex portion 222a of the prior art is not scraped. Therefore, even if the clip 1 is remounted, the drop-off preventing function of the remounted clip 1 is not deteriorated.

  Further, according to this configuration, in the plan view of the clip mounting seat 3, the edge 30 a on the mounting hole 24 side in the warp 30 is the first angle α (acute angle with respect to the edge 26 a of the guide groove 26, for example, (About 60 °). Therefore, when both the warps 30 act as a drop-off prevention function, for example, the drop-off prevention function can be strengthened as compared with the case where the first angle α is an obtuse angle.

(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIGS. Compared with the clip mounting seat 3 of the first embodiment already described, the clip mounting seat 103 of the second embodiment has a neck portion 14c of the clip 1 toward the guide groove 26 of the clip mounting seat 3 when the clip 1 is mounted. It is the form which can perform guidance of reliably. In the following description, the same members as those described in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description is omitted.

  As shown in FIGS. 11 to 12, an extension 28 a is formed at the distal end of the flexure piece 28 so that the guide groove 26 is warped and extends toward the distal end side of the 30 (the receiving side of the clip 1). Yes. The other configuration is the same as that of the clip mounting seat 3 of the first embodiment in the clip mounting seat 103 of the second embodiment.

  The clip mounting seat 103 of the interior part 2 according to the second embodiment of the present invention is configured as described above. According to this structure, the same effect as the clip mounting seat 3 of the interior part 2 of Example 1 can be obtained. Further, according to this configuration, the extension 28 a is formed at the tip of the bending piece 28. When formed in this way, the guide groove 26 is formed to extend to the tip side of the warp 30 (the receiving side of the clip 1). Therefore, when the clip 1 is mounted on the clip mounting seat 3, the neck portion 14c of the clip 1 can be temporarily guided to the extended portion of the guide groove 26, and then the neck portion 14c of the clip 1 can be guided toward the guide groove 26. . Therefore, compared with the clip mounting seat 3 of the first embodiment, the clip 1 toward the guide groove 26 of the clip mounting seat 3 is temporarily provided to temporarily guide the neck portion 14c of the clip 1 to the extended portion of the guide groove 26. The neck portion 14c can be reliably guided.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In each of the embodiments, the form in which “interior part 2” is “instrument panel, door trim, etc.” has been described. However, the present invention is not limited to this, and the “interior part 2” may be “various resin molded products”.

  Moreover, in each Example, when mounting the clip 1 to the clip mounting surface 22 of the clip mounting seat 3, the upper collar part 14a of the clip 1 pushed both sides 30 and pushed in 30 form was demonstrated. However, the present invention is not limited to this, and the stabilizer 10a of the clip 1 may be configured to push in the opposite side 30.

  Moreover, in each Example, the form where the thickness of the bending piece 28 was constant was demonstrated (refer FIG. 4). However, it is not limited to this, The thickness of the bending piece 28 may be formed thinly toward the front-end | tip. At this time, the thin shape toward the tip may be formed such that the lower surface of the flexure piece 28 is inclined upward toward the tip (see FIG. 13, Modification 1). Of course, on the contrary, the upper surface of the bending piece 28 may be formed so as to incline downward toward the tip (see FIG. 14, Modification 2). When the clip 1 is mounted on the clip mounting surface 22 of the clip mounting seat 3 of the interior part 2, the pair of bending pieces 28 can be bent with a light operation load. Therefore, it is possible to suppress the operation load when the clip 1 is mounted.
