Description

  The present invention relates to an attachment structure using a clip for detachably attaching an attachment member to a member to be attached. Specifically, for example, a clip mounting structure for detachably mounting a center cluster or the like on an instrument panel of an automobile, which can exhibit different holding loads according to the shape of the mounting hole It relates to the mounting structure.

As a conventional technique, a clip disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-249117 (Patent Document 1) is known as a clip for detachably mounting a center cluster or the like on an instrument panel of an automobile.
The clip disclosed in Patent Document 1 is formed by forming a resin-made clip body attached to a seat member disposed in a projecting state on a center cluster as an attachment member on an instrument panel as an attached member. It is a clip used for locking the mounting member to the mounted member by inserting it from the surface side of the mounting hole and detachably mounting the mounting member to the mounted member.

FIG. 23 is a partial cross-sectional view showing a state in which the attachment member is attached to the attached member using substantially the same clip as that disclosed in Patent Document 1. The resin clip main body 50 engages the engagement protrusion 54 formed at the tip of the seat surface engagement portion piece 52 with the engagement hole 70 of the seat surface member 68 formed in the attachment member 66. As a result, it is attached to the attachment member 66. Then, the resin-made clip main body 50 engaged with the attachment member 66 is inserted from the surface side 76 into the attachment hole 74 formed in the attached member 72, and the attachment locking piece 58 of the clip main body 50 is locked. The engaging slope 66 formed at the lower portion of the shoulder 60 is engaged with the back side 78 of the attached member 72, whereby the attaching member 66 is attached to the attached member 72.
When it is necessary to remove the mounting member 66 from the mounted member 72, the mounting member 66 is pulled away from the mounted member 72 to elastically deform the mounting locking pieces 58 of the clip body 50 toward each other. Then, since the engaging slope 62 at the lower part of the locking shoulder 60 is detached from the back surface side 78 of the attached member 72, the attaching member 66 can be detached from the attached member 72 integrally with the clip body 50.
The clip body 50 is attached to the attachment member 66 because the engagement protrusion 54 at the tip of the seat surface engagement piece 52 engages with the engagement hole 70 formed in the seat surface member 68. When the surface engaging part piece 52 is elastically deformed and the engaging protrusion 54 is disengaged from the engaging hole 70, the clip main body 50 remains in the attached member 72 and only the attaching member 66 is removed from the attached member 72. You can also.
JP 2000-249117 A

With the clip main body 50 shown in FIG. 23, the attachment member 66 can be attached to the attached member 72 with a predetermined holding load. When it is necessary to change the holding load, the angle or area of the engagement surface 56 of the engagement protrusion 54 of the clip body 50 is changed, or the distance between the engagement shoulders 60 of the pair of attachment engagement pieces 58 is changed. Further, it is necessary to take measures such as changing the inclination angle of the engaging slope 62 or changing the material of the clip body 50. Here, since the holding load by the engaging projection 54 is generally set higher than the holding load by the engaging slope 62, the holding load by the clip main body 50 depends on the distance between the two engaging shoulders 60 and the engaging slope 62. It depends on the angle.
Therefore, in order to support mounting with different holding loads, it has been necessary to prepare multiple types of clip bodies with different shapes and materials, and select the clip body corresponding to the holding load at the mounting location. Had to install.

  The present invention proposes to solve the above-described problems, and the problem to be solved by the present invention is that the mounting member is formed using the same type of clip body without changing the shape and material of the clip body. It is possible to cope with different holding loads without changing the insertion load when the is attached to the attached member.

In order to solve the above-mentioned problems, the mounting structure using a clip according to the present invention takes the following means.
First, the clip mounting structure according to the first aspect of the present invention is such that a clip structure in which a resin clip main body is mounted on a seat member disposed in a projecting manner on the mounting member is formed on the mounted member. A mounting structure with a clip that is inserted into the mounting hole from the front side to the back side in the insertion direction of the mounted member, and the mounting member is detachably mounted to the mounted member,
The resin-made clip main body is formed on the inside, a pair of seating surface engaging part pieces that sandwich the seating surface member from both sides, and formed on the outside of the seating surface engaging part piece, and the attached member A pair of mounting locking pieces that are inserted through and locked in the mounting holes and provided with elasticity in the expanding direction,
The mounting locking piece is formed with a projection in the shape of a mountain on the outer side, and has an insertion inclined surface that generates a resilient force by being deformed in proximity when inserted, and a locking inclined surface that performs a locking function in the extraction direction. And
The insertion inclined surfaces of the mounting locking pieces are formed in the same inclined state, and the inclined inclined surfaces have a plurality of inclined surfaces having different inclined states with a predetermined thickness in the thickness direction orthogonal to the expanding direction. Are formed adjacent to each other, and the inclined inclined surfaces on both sides in the expanding direction are formed correspondingly to the inclined surfaces in the same inclined state,
The mounting hole formed in the member to be mounted can be set to a plurality of types of mounting holes corresponding to the plurality of inclined surfaces, and the plurality of types of mounting holes are among the plurality of inclined surfaces having different inclined states. A locking hole having a hole size capable of locking any one inclined surface having the same inclined state, and a relief hole having a hole size not locking any other inclined surface; Are formed as one continuous hole,
A mounting hole selected from the plurality of types of mounting holes is formed in the mounted member according to a holding load required for the mounted member of the mounting member, and the selected mounting hole is formed in the selected mounting hole. The clip structure to which the clip body having the plurality of inclined surfaces is attached is inserted and locked.

According to the first aspect, the clip body is formed with a plurality of types of inclined surfaces corresponding to the holding load. Only the inclined surface having the same inclined state is locked to the locking hole, and the inclined surface corresponding to the other holding load has a plurality of mounting holes formed so as not to be locked to the mounting hole in order to correspond to the escape hole. Type is set. Therefore, the holding load exerted by the clip main body is determined by selecting the mounting hole in which the inclined surface in the specific inclined state is locked. Therefore, the holding load by the same clip can be varied by varying the mounting holes formed in the mounted member.
Further, since the insertion inclined surface is formed in the same inclined state, the insertion load is the same when inserted into any of the attachment holes, and the insertion load does not change even if the holding load is increased by changing the attachment hole.

Next, 2nd invention of this invention is the attachment structure by the clip concerning the said 1st invention, Comprising:
The mounting hole has an opening length in a direction corresponding to the thickness direction of the clip body, and the clip structure is allowed to move in the opening length direction while being attached to the mounting hole.
Regardless of the position of the mounting hole in the mounting hole, a locking hole is formed at a position corresponding to the inclined surface that exerts a drag according to the holding load, and at a position corresponding to another inclined surface. Is characterized in that only escape holes are formed.
According to the second aspect of the invention, even if the attachment position moves due to play in the length direction of the attachment hole, only the selected inclined surface in the engagement state is engaged with the engagement hole, Since the other inclined surfaces in the locked state are not locked, even if the mounting position of the clip structure moves in the length direction of the mounting hole, the holding load does not change. Therefore, the reliability with respect to the holding load is high.

Next, a third invention of the present invention is a mounting structure using a clip according to the second invention,
An inclined surface having the same inclined state and the same thickness is formed at both ends in the thickness direction of the locking inclined surface, and one inclined surface having a different inclined state is formed between the inclined surfaces. It is characterized by being formed symmetrically.
According to the third aspect of the invention, since the clip body is bilaterally symmetric, the locking position at the time of removal is bilaterally symmetric and good balance is obtained. Further, since the clip body is also symmetric in the thickness direction, it has a rotational symmetry of 180 degrees, and there is no need to be aware of the orientation when the clip body is attached to the seat member.

Next, a fourth invention of the present invention is a mounting structure using a clip according to the second invention,
Two inclined surfaces with different inclination states are formed with the same width on the engaging inclined surface, and two inclined surfaces corresponding to these inclined surfaces and the inclined state are formed on the other engaging inclined surface, respectively. It is characterized by being formed in the same width and in the reverse order of the thickness direction.
According to the fourth aspect of the invention, when the inclined surface in any inclined state is locked in the locking hole, the locking length is the same, so that the balance is good. In addition, since the clip body is rotationally symmetric, there is no need to be aware of the orientation when the clip body is attached to the seat member.

According to the first aspect, the clip main body is formed with a plurality of types of inclined surfaces corresponding to the holding load. Only the inclined surface having the same inclined state is locked to the locking hole, and the inclined surface corresponding to the other holding load has a plurality of mounting holes formed so as not to be locked to the mounting hole in order to correspond to the escape hole. Type is set. Therefore, the holding load exerted by the clip main body is determined by selecting the mounting hole in which the inclined surface in the specific inclined state is locked. Therefore, the holding load by the same clip can be varied by varying the mounting holes formed in the mounted member. Further, since the insertion inclined surface is formed in the same inclined state, the insertion load is the same when inserted into any of the attachment holes, and the insertion load does not change even if the holding load is increased by changing the attachment hole.
According to the second aspect of the invention, even when the attachment position moves due to play in the length direction of the attachment hole, only the selected inclined surface in the engagement state is engaged with the engagement hole, Since the other inclined surfaces in the locked state are not locked, even if the mounting position of the clip structure moves in the length direction of the mounting hole, the holding load does not change. Therefore, the reliability with respect to the holding load is high.
According to the third aspect of the invention, since the clip body is bilaterally symmetric, the locking position at the time of removal is bilaterally symmetric and good balance is obtained. Further, since the clip body is also symmetric in the thickness direction, it has a rotational symmetry of 180 degrees, and there is no need to be aware of the orientation when the clip body is attached to the seat member.
According to the fourth aspect of the invention, when the inclined surface in any inclined state is locked in the locking hole, the locking length is the same, so that the balance is good. In addition, since the clip body is rotationally symmetric, there is no need to be aware of the orientation when the clip body is attached to the seat member.

<First Example>
Hereinafter, the best mode for carrying out the present invention will be described.
FIG. 1 shows an external perspective view of a clip body 10 used in the mounting structure with a clip according to the first embodiment of the present invention in a free state shape. The clip 10 is formed of a resin, and a pair of seating surface engaging portion pieces 14 formed on the inside and a pair of outer surface forming the seating surface engaging portion piece 14 and provided with elasticity in the expanding direction. The mounting locking piece 20 is provided. Further, the mounting locking piece 20 is formed with a projection in the shape of a mountain on the outside, and an insertion inclined surface 22 that generates a resilient force by being deformed in the vicinity when inserted, and a locking slope that performs a locking function in the extraction direction. A locking shoulder 25 having a maximum width of the protruding portion is formed between the insertion inclined surface 22 and the locking inclined surface 24. A leg piece 21 is formed behind the locking inclined surface 24 in the insertion direction.
The insertion inclined surface 22 is formed in the same inclined state in the thickness direction orthogonal to the expanding direction of the mounting locking piece 20 and has a symmetrical shape in the expanding direction. On the other hand, the inclined inclined surface 24 is formed with a first inclined surface 26 that is gently inclined at both ends in the thickness direction, and the first inclined surface 26 is inclined with the same thickness as the first inclined surface 26. A second inclined surface 28 whose state is steeper than the first inclined surface 26 is provided and formed. And the attachment locking piece 20 of the clip main body 10 has a symmetrical shape in the expanding direction and the thickness direction.
In the description of the examples, also in the other examples, the first inclined surface and the second inclined surface are named in order from the inclined surface in which the inclined state is gentle.

  FIG. 2 is an external perspective view of the seat member 32 formed on the mounting member 30 used in one embodiment of the present invention. The seat surface member 32 is formed with an engagement plate 34 for engaging the seat surface engaging portion piece 14 of the clip body 10 at the center, and the seat surface engaging portion piece 14 of the clip body 10 is formed at the center portion of the engagement plate 34. An engagement hole 36 is provided for engaging the engagement protrusion 16 formed at the tip of the engagement hole 16. An engagement slope 39 having a thin plate thickness is formed at the front end of the engagement plate 34 in order to facilitate the engagement of the seating surface engagement piece 14. Both side plates 38 are formed on both sides of the engagement plate 34 and serve as a guide when the clip body 10 is engaged with the seat surface member 32 and also serves as a reinforcement of the seat surface member 32.

FIG. 3A shows a back surface to which the clip structure 12 in which the clip main body 10 is attached to the seat member 32 is engaged with the first attachment hole 42 used in the first embodiment of the present invention to realize a low holding load. FIG. 5 is an external perspective view seen from the side 48. When the clip structure 12 is inserted, the first mounting hole 42 has a locking hole 44 at a position where the first inclined surface 26 faces the first mounting hole 42, and a second inclined surface 28 at the first mounting hole 42. A relief hole 46 is formed continuously in the opening length direction of the first mounting hole 42 at the facing position. The locking hole 44 and the relief hole 46 are formed so that the centers in the width direction are on the same line, and the first mounting hole 42 is generally symmetrical in the length direction and the width direction. The length of the relief hole 46 is set to be longer than the length of the locking hole 44, and the width of the relief hole 46 is set to the width of the locking shoulder 25 in the free state shape of the clip body 10.
FIG. 3B is an external perspective view of the second mounting hole 43 used in the first embodiment to realize a high holding load as viewed from the back side 48 where the clip structure 12 is locked. The difference from the first mounting hole 42 is that the relief hole 46 is formed with the same width as the locking hole 44, and there is no distinction between the locking hole 44 and the relief hole 46. The reason for this will be described later.
The opening lengths of the first mounting hole 42 and the second mounting hole 43 are such that the clip structure 12 has a play that allows movement in the opening length direction with the clip structure 12 inserted. Has been. Therefore, it is easy to insert the clip structure 12.

Here, returning to FIG. 1, the detailed shapes of the first inclined surface 26 and the second inclined surface 28 will be described. Immediately below the locking shoulder 25, a straight portion is formed which is common to the first inclined surface 26 and the second inclined surface 28 and is substantially parallel to the insertion direction of the clip body 10. The straight portion is formed longer on the second inclined surface 28 than on the first inclined surface 26. Following the straight portion, a locking portion that locks in the locking hole toward the leg piece 21 and exhibits a holding force is formed. The locking portion of the second inclined surface 28 has an abrupt change in inclination and the length in the insertion direction of the clip 10 is shorter than that of the system stopping portion of the first inclined surface 26. It has already hit the leg piece 21 in the upper direction of insertion. And there is a neutral position 27 where the amount of protrusion of both locking portions is the same. The clip main body 10 exhibits the maximum holding load on each inclined surface when the locking portion is locked in the locking hole 44 above the neutral position 27.
When the engaging part of the second inclined surface 28 is engaged with the engaging hole 44, the engaging part and the engaging hole are more engaged than when the engaging part of the first inclined surface 26 is engaged with the engaging hole 44. Since the angle formed by 44 is large, a larger drag force is generated in the extraction direction, so the holding load is large.

  When the attachment member 30 is attached to the attachment member 40 using the clip body 10, the following procedure is performed. First, the pair of seating surface engaging portion pieces 14 of the clip main body 10 are slid to both sides of the engaging slope 39 formed on the engaging plate 34 of the seating surface member 32 to be formed at the tip of the seating surface engaging portion piece 14. The clip body 10 is attached to the attachment member 30 by engaging the seating surface engagement protrusion 16 with the engagement hole 36 formed at the center of the engagement plate 34. At this time, since the seating surface engaging piece 14 has the same shape in the thickness direction of the clip body 10, it can be attached in a direction rotated by 180 degrees. Next, the clip structure 12 with the clip body 10 attached to the seat member 32 is inserted into the attachment hole 42 formed in the attached member 40 from the surface side 47 to attach the attachment member 30 to the attached member 40. .

FIG. 4 is an external perspective view of the clip structure 12 with the first mounting holes 42 formed in the mounted member 40 attached thereto. When the clip main body 10 is deformed close to one another in the thickness direction in the expanding direction, the clip main body 10 has a property of being deformed close to the width of almost the same in the entire thickness direction. Therefore, as shown in FIG. In a state where the second inclined surface 28 is deformed in proximity by being locked in the locking hole 44, the second inclined surface 28 is also deformed in proximity by substantially the same width as the first inclined surface 26. Then, as shown in FIG. 4, in the state where the first inclined surface 26 that is gently inclined is locked to the locking hole 44, the second inclined surface 28 that is sharply inclined faces the escape hole 46 and is attached to the first mounting surface. It is in a state separated from the hole 42.
Even if the mounting position of the clip structure 12 moves in the play direction of the first mounting hole 42, the first inclined surface 26 that exerts the holding load does not come off from the locking hole 44, and the surface of the escape hole 46 faces the surface. The lengths of the locking hole 44 and the relief hole 46 are set so that the second inclined surface 28 does not relate to the locking hole 44. For this reason, the latching state with respect to the 1st attachment hole 42 of the clip structure 12 does not change by the movement of the clip structure 12 in the play direction.
FIG. 5 is a cross-sectional view taken along the line AA in FIG. At the position where the first inclined surface 26 is locked to the locking hole 44, the first inclined surface 26 locked to the locking hole 44 in the pulling direction exhibits a drag force. 6 is a cross-sectional view taken along line BB in FIG. At the position where the second inclined surface 28 faces the escape hole 46, the width of the escape hole 46 is the same as the width of the locking shoulder 25 in the free state shape of the clip body 10. It is not locked in the escape hole 46.

FIG. 7 is an external perspective view of the clip structure 12 with the second attachment holes 43 formed in the attached member 40 attached thereto. When the clip body 10 is deformed in the expansion direction in the proximity of any one part in the thickness direction, the clip body 10 has the property of being deformed in the entire thickness direction by substantially the same width. Therefore, as shown in FIG. In a state where the first inclined surface 26 is deformed in proximity by being locked in the locking hole 44, the first inclined surface 26 is also deformed in proximity by substantially the same width as the second inclined surface 28.
Here, in the state where the clip structure 12 is attached to the attached member 40, the position where the engaging inclined surface 24 of the clip body 10 is engaged with the first attachment hole 42 on the back surface side 48 of the attached member 40 is as described above. In this position, the width of the locking portion of the gently sloping first inclined surface 26 is narrower than the width of the locking portion of the steep second inclined surface 28. Therefore, as shown in FIG. 7, in a state where the steep second inclined surface 28 is locked in the locking hole 44, the gently sloping first inclined surface 26 is a relief hole having the same width as the locking hole 44. It is in a state away from 46.
8 is a cross-sectional view taken along the line CC of FIG. At the position where the first inclined surface 26 faces the escape hole 46 having the same width as the locking hole 44, the width of the first inclined surface 26 is narrower than the width of the second inclined surface 28. The surface 26 is not locked into the escape hole 46. 9 is a cross-sectional view taken along the line DD of FIG. At the position where the second inclined surface 28 is locked in the locking hole 44, the second inclined surface 28 exhibits a drag force.

The drag in the pulling direction of the clip body 10 is determined by the angle formed by the locking inclined surface 24 and the mounting hole 42 where the drag is generated, and the thickness of the locking inclined surface 24 that is deformed in proximity. When one part is deformed in proximity in the spreading direction, it has the property of being deformed in proximity by a substantially equal width throughout the entire thickness direction.
Therefore, the holding load when the clip structure 12 is attached to the first attachment hole 42 where the first inclined surface 26 is engaged with the engaging hole 44 is the same as that of the first inclined surface 26. The clip body 10 formed in an inclined state is almost the same as the holding load when the attachment hole 42 is attached to the attachment hole formed with the width of the locking hole 44 over the entire opening length.
The holding load when the second inclined surface 28 is attached to the second attachment hole 43 that is engaged with the engaging hole 44 is formed so that the entire engaging inclined surface 24 is in the same inclined state as the second inclined surface 28. The holding load when the clip body is attached to the second attachment hole 43 is approximately the same.

Therefore, by using the clip body 10 having the same shape and selecting the shape of the mounting hole formed in the mounted member 40 as the first mounting hole 42 or the second mounting hole 43, two types of holding It can correspond to the load. And since the insertion inclined surface 22 is formed in the same inclination state, the insertion load is the same even when it is inserted into any of the attachment holes, and the insertion load does not change even if the holding load is increased by changing the attachment holes.
Moreover, since the clip main body 10 is bilaterally symmetric, the locking position at the time of removal is bilaterally symmetric and good balance is obtained. Further, since the clip body 10 is also symmetric in the thickness direction, it is 180 degrees rotationally symmetric, and there is no need to be aware of the orientation when the clip body 10 is attached to the seat member 32.

<Second Example>
FIG. 10 shows an external perspective view of a clip main body 10A used in the mounting structure using clips according to the second embodiment of the present invention. Compared with the first embodiment, the first inclined surface having a gentle inclination is located at the center in the thickness direction, and the second inclined surfaces having a sharp inclination are located on both sides thereof. Since the seat member 32 formed on the mounting member 30 used in the second embodiment is the same as that used in the first embodiment, description thereof is omitted.
FIG. 11A shows a first mounting hole 42A for realizing a low holding load in the second embodiment, and FIG. 11B shows a second mounting hole 43A for realizing a high holding load in the second embodiment. Indicates. Compared to the case of the first embodiment, the first mounting hole 42A for low holding load is characterized in that a locking hole 44 is formed at the center in the opening length direction, and relief holes 46 are formed at both ends thereof. It is. The second mounting hole 43A is similar to the second mounting hole 43, and there is no difference in the hole width between the locking hole 44 and the escape hole 46.

  The opening length of the first mounting hole 42A and the second mounting hole 43A is a length having a play that allows the clip structure 12A to move in the opening length direction with the clip structure 12A inserted. This is the same as in the first embodiment. The lengths of the locking hole 44 and the relief hole 46 are set so that the locking state of the clip body 10A with respect to the first mounting hole 42A does not change even if the clip body 10A moves in the play direction of the first mounting hole 42A. This is the same as in the first embodiment.

When the clip structure 12A using the clip main body 10A is inserted into the first mounting hole 42A, only the first inclined surface 26 formed at the central portion in the thickness direction of the clip main body 10A is locked to the locking hole 44 and low. A holding load is obtained. When the clip structure 12A is inserted into the second mounting hole 43A, only the second inclined surfaces 28 formed at both ends in the thickness direction of the clip main body 10A are locked to the locking holes 44 to obtain a high holding load. And since the insertion inclined surface 22 is formed in the same inclined state, the insertion load is the same even when it is inserted into any of the mounting holes, and the insertion load does not change even if the holding load is increased by changing the mounting hole. Is the same as in the first embodiment.
Further, since the clip main body 10A is symmetric, the locking position at the time of removal is symmetric, and the balance is good. The clip main body 10A is 180 degrees rotationally symmetric, and the clip main body 10A is used as a seat member. It is the same as that of the first embodiment in that it is not necessary to be aware of the direction when attaching to 32.

<Third embodiment>
FIG. 12 shows an external perspective view of a clip main body 10B used in the mounting structure with clips according to the third embodiment of the present invention. The clip body 10B has the same basic shape and properties as the clip body 10 used in the first embodiment except for the shape of the locking inclined surface 24. The locking inclined surface 24 on one side of the clip body 10B is adjacent to a first inclined surface 26 that is gently inclined and a second inclined surface 28 that is inclined more steeply than the first inclined surface 26 with the same thickness. The other inclined inclined surface 24 is formed with inclined surfaces corresponding to the first inclined surface 26 and the second inclined surface 28 in reverse order in the thickness direction. Therefore, the clip body 10B has a rotationally symmetric shape with respect to the insertion direction.

  The seat member 32 formed on the mounting member 30 used in the third embodiment is the same as that used in the first embodiment shown in FIG.

FIG. 13A is an external perspective view of the first mounting hole 42B used in the third embodiment of the present invention to realize a low holding load as viewed from the back side 48 where the clip body 10B is engaged. When the clip structure 12B having the clip body 10B attached to the seat member 32 is inserted, the first attachment hole 42B has a locking hole 44 at a position where the first inclined surface 26 faces the first attachment hole 42B. A relief hole 46 is formed at a position where the two inclined surfaces 28 face the first mounting hole 42B.
FIG. 13B is a perspective view of the second mounting hole 43B used in the third embodiment for realizing a high holding load as viewed from the back side 48 where the clip body 10B is engaged. The difference from the first mounting hole 42B is that the positions of the locking hole 44 and the escape hole 46 are interchanged.
The escape hole 46 is formed slightly longer than the locking hole 44.
Here, the opening lengths of the first mounting hole 42B and the second mounting hole 43B are the same as in the above-described embodiment, and the clip structure 12B is allowed to move in the opening length direction with the clip structure 12B inserted. It is said that it has a length with play. Therefore, it is easy to insert the clip structure 12B.

FIG. 14 is an external perspective view of the clip structure 12 </ b> B attached to the first attachment hole 42 </ b> B formed in the attached member 40. When the clip body 10B is deformed close to one another in the thickness direction in the expanding direction, the clip main body 10B has a property of being deformed close to substantially the same width in the entire thickness direction. Therefore, as shown in FIG. In a state where the second inclined surface 28 is deformed in proximity by being locked in the locking hole 44, the second inclined surface 28 is also deformed in proximity by substantially the same width as the first inclined surface 26. Then, as shown in FIG. 14, in the state where the first inclined surface 26 having the inclined state is locked to the locking hole 44, the second inclined surface 28 having the inclined state faces the escape hole 46 and is attached to the first mounting surface. It is in a state separated from the hole 42B.
FIG. 15 is a cross-sectional view taken along line EE in FIG. At this position, the first inclined surface 26 is engaged with the engagement hole 44 on the left side of the drawing, and the second inclined surface 28 is separated from the escape hole 46 on the right side of the drawing. FIG. 16 is a sectional view taken along line FF in FIG. At this position, the second inclined surface 28 is separated from the escape hole 46 on the left side of the drawing, and the first inclined surface 26 is locked to the locking hole 44 on the right side of the drawing.
Therefore, when the clip structure 12B is mounted in the first mounting hole 42B, only the first inclined surface 26 formed diagonally is locked in the locking hole 44 formed in the diagonal direction. Since the main body 10B is locked to the first mounting hole 42B, a low holding load is obtained by the first inclined surface 26.

FIG. 17 is an external perspective view of the clip structure 12 </ b> B attached to the second attachment hole 43 </ b> B formed in the attached member 40. When the clip main body 10B is deformed close to one another in the thickness direction in the spreading direction, the clip main body 10B has a property of being deformed close to the entire width direction by substantially the same width. Therefore, as shown in FIG. In a state where the first inclined surface 26 is deformed in proximity by being locked in the locking hole 44, the first inclined surface 26 is also deformed in proximity by substantially the same width as the second inclined surface 28. Then, in the state where the steep second inclined surface 28 in the inclined state is locked in the locking hole 44 as shown in FIG. 17, the first inclined surface 26 in the inclined state faces the escape hole 46 and is attached to the second mounting surface. It is in a state separated from the hole 43B.
FIG. 18 shows a GG cross-sectional view of FIG. In this position, the first inclined surface 26 is separated from the escape hole 46 on the left side of the drawing, and the second inclined surface 28 is locked to the locking hole 44 on the right side of the drawing. FIG. 19 is a cross-sectional view taken along the line HH in FIG. At this position, the second inclined surface 28 is engaged with the engagement hole 44 on the left side of the drawing, and the first inclined surface 26 is separated from the escape hole 46 on the right side of the drawing.
Therefore, when the clip structure 12B is mounted in the second mounting hole 43B, only the second inclined surface 28 formed diagonally is locked in the locking hole 44 formed diagonally opposite to each other. Since the main body 10B is locked in the second mounting hole 43B, a high holding load is obtained by the second inclined surface 28.
In addition, according to this embodiment, when the inclined surface in any inclined state is locked in the locking hole 44, the locking length is the same, so that the balance is good. Further, since the clip body 10B is rotationally symmetric, there is no need to be aware of the orientation when the clip body 10B is attached to the seat member 32.

  Even if the mounting position of the clip structure 12B moves in the play direction of the first mounting hole 42B or the second mounting hole 43B, the inclined surface that exerts the holding load does not come off from the locking hole 44, and the escape hole. Since the length of the locking hole 44 and the relief hole 46 is set so that the inclined surface facing the 46 does not relate to the locking hole 44, the clip structure 12B is moved by the movement of the clip structure 12B in the play direction. The locking state with respect to the first mounting hole 42B or the second mounting hole 43B does not change.

Therefore, by using the clip body 10B having the same shape and selecting whether the shape of the mounting hole formed in the mounted member 40 is the first mounting hole 42B or the second mounting hole 43B, two types of holding are performed. It can correspond to the load.
In addition, according to this embodiment, when the inclined surface in any inclined state is locked in the locking hole 44, the locking length is the same, so that the balance is good. Further, since the clip body 10B is rotationally symmetric, there is no need to be aware of the orientation when the clip body 10B is attached to the seat member 32.

<Fourth embodiment>
FIG. 20 shows an external perspective view of a clip main body 10C used in the mounting structure using clips according to the fourth embodiment of the present invention. The clip body 10 </ b> C has the same basic shape and properties as the clip body 10 used in the first embodiment except for the shape of the locking inclined surface 24. The one inclined inclined surface 24 of the clip main body 10 </ b> C has a first inclined surface 26 that is gently inclined, a second inclined surface 28 that is steeper than the first inclined surface 26, and a second inclined surface 28. A third inclined surface 29 having a steep inclination is adjacently formed with the same thickness, and the other inclined inclined surface 24 includes a first inclined surface 26, a second inclined surface 28, and a third inclined surface. An inclined surface corresponding to 29 is formed in the reverse order in the thickness direction. Therefore, the clip body 10C has a rotationally symmetric shape with respect to the insertion direction. In these three types of inclined surfaces, the neutral positions 27 where the widths of the locking portions are the same are on the same line and coincide. FIG. 21 shows a front view of the clip main body 10C.

  The seat member 32 formed on the mounting member 30 used in the fourth embodiment is the same as that used in the first embodiment shown in FIG.

FIG. 22A is a perspective view of the first mounting hole 42C used in the fourth embodiment of the present invention to realize a low holding load as viewed from the back side 48 where the clip body 10C is engaged. When the clip structure 12C in which the clip body 10C is attached to the seat member 32 is inserted, the first attachment hole 42C has a locking hole 44 at a position where the first inclined surface 26 faces the first attachment hole 42C. An escape hole 46 is formed at a position where the second inclined surface 28 and the third inclined surface 29 face the first mounting hole 42C.
FIG. 22B is a perspective view of the second mounting hole 43C used in the fourth embodiment of the present invention to realize a high holding load, as viewed from the back side 48 where the clip body 10C is locked. When the clip structure 12C is inserted, the second mounting hole 43C has a locking hole 44 at a position where the second inclined surface 28 faces the second mounting hole 43C, and the first inclined surface 26 and the third inclined surface 29. An escape hole 46 is formed at a position facing the second mounting hole 43C.
FIG. 21C is a perspective view of the third mounting hole 43D used in the fourth embodiment of the present invention for realizing the maximum holding load as viewed from the back side 48 where the clip body 10C is engaged. When the clip structure 12C is inserted, the third mounting hole 43D has a locking hole 44 at a position where the third inclined surface 28 faces the third mounting hole 43D, and the first inclined surface 26 and the second inclined surface 28. An escape hole 46 is formed at a position facing the third mounting hole 43D.

Here, the opening lengths of the first mounting hole 42C, the second mounting hole 43C, and the third mounting hole 43D are such that the clip structure 12C is allowed to move in the opening length direction with the clip structure 12C inserted. It is said that it has a length of play. Therefore, it is easy to insert and remove the clip structure 12C.
Even if the mounting position of the clip structure 12C moves in the play direction of these mounting holes, the inclined surface that exerts the holding load on the holding load does not come off from the locking hole 44 and faces the escape hole 46. Since the length of the locking hole 44 and the relief hole 46 is set so that the inclined surface does not relate to the locking hole 44, the holding load does not change due to the movement of the clip structure 12C in the play direction. .

When the clip structure 12C is attached to the first attachment hole 42C, only the first inclined surface 26 is engaged with the engagement hole 44, and a low holding load is obtained. When the clip structure 12C is attached to the second attachment hole 43C, only the second inclined surface 28 is engaged with the engagement hole 44 to obtain a high holding load. When the clip structure 12C is attached to the third attachment hole 43D, only the third inclined surface 29 is engaged with the engagement hole 44, and the maximum load is obtained.
When an inclined surface with a higher holding load is locked in the locking hole 44, the width of the relief hole 46 at a position where the inclined surface with a lower holding load faces the mounting hole 42 is the same as in the first embodiment. In addition, the same width as the locking hole 44 may be used. Similar to the clip body 10, the clip body 10 </ b> A has the property that if any one part in the thickness direction is deformed close in the expanding direction, the clip body 10 </ b> A is deformed in proximity to the entire region in the thickness direction by approximately the same width. This is because, in a state where the high inclined surface is locked in the locking hole 44, the inclined surface having a lower holding load is deformed close to a width that cannot be locked in the locking hole 44.

According to this embodiment, by using the same clip main body 10C, the shape of the mounting hole can be selected from three types, so that three types of holding loads can be handled. And since the insertion inclined surface 22 is formed in the same inclination state, the insertion load is the same even when it is inserted into any of the attachment holes, and the insertion load does not change even if the holding load is increased by changing the attachment holes.
In addition, even when any inclined surface in the inclined state is locked in the locking hole 44, the length to be locked is the same, so the balance is good. Further, since the clip body 10C is rotationally symmetric, there is no need to be aware of the orientation when the clip body 10C is attached to the seat member 32.

  In the above-described embodiment, the width of the escape hole is based on the width of the engagement shoulder in the free state shape of the clip body, except for the case where the width of the release hole is the same as the width of the engagement hole. The inclined surface is not limited to the escape hole, and is not limited to the width of the embodiment. When there is a part where the width of the inclined surface that you do not want to lock is wider than the inclined surface that you want to lock at each position in the insertion direction of the clip body, the difference in one side with respect to the center position of the locking hole It is sufficient that the escape hole is formed wider than the locking hole by the maximum value of.
