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, the present invention relates to a mounting structure using a clip for detachably mounting a center cluster or the like on an instrument panel of an automobile.

As a conventional technique, for example, a clip disclosed in Japanese Patent 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. 26 shows a partial cross-sectional view of 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 40 engages the engagement protrusion 43 formed at the tip of the seat surface engagement portion piece 42 with the engagement hole 54 of the seat surface member 52 formed in the attachment member 50. Is attached to the attachment member 50. In addition, the resin clip main body 40 engaged with the attachment member 50 is inserted into the attachment hole 62 formed in the attachment target member 60 from the surface side 64 and formed on the attachment locking piece 46 of the clip main body 40. The attachment member 50 is attached to the attachment member 60 by the engagement shoulder 47 engaging the back surface side 66 of the attachment member 60.
When it is necessary to remove the mounting member 50 from the mounted member 60, the mounting locking piece 46 of the clip body 40 is elastically deformed inward by pulling the mounting member 50 strongly, so that the locking shoulder 47 is covered. The attachment member 50 is detached from the back surface side 66 of the attachment member 60, and the attachment member 50 can be detached from the attachment member 60 together with the clip body 40.
The clip main body 40 is attached to the attachment member 50 by engaging the engagement protrusion 43 at the tip of the seat surface engagement portion piece 42 with the engagement hole 54 formed in the attachment member 50. If the surface engaging portion 42 is elastically deformed and the engaging protrusion 43 is disengaged from the engaging hole 54, it is possible to leave only the attaching member 50 from the attached member 60 while leaving the clip body 40 in the attached member 60. .
JP 2000-249117 A

With the clip main body 40 shown in FIG. 26, the attachment member 50 can be attached to the attached member 60 with a predetermined holding load. However, when it becomes necessary to change the holding load, the clip body 40 cannot be used as it is, and the angle or area of the engagement surface 44 of the engagement protrusion 43 of the clip body 40 is changed or attached. A different clip body having a different holding load from the clip body 40 is required by changing the width and angle of the locking shoulder 47 of the locking piece 46 or changing the material of the clip body 40. there were.
Therefore, in order to support mounting with different holding loads, it is necessary to prepare multiple types of clip bodies with different shapes and materials. did not become.

  The present invention is proposed as a solution to the above-described problem, and the problem to be solved by the present invention is to change the thickness of the seat member and to change the shape without changing the shape or material of the clip body. By changing or the like, when the attachment member is attached to the attached member using the same type of clip body, it is possible to cope with different holding loads.

In order to solve the above problems, the clip mounting structure according to the present invention takes the following means.
First, the clip mounting structure according to the first aspect of the present invention is a clip structure in which a resin clip main body is mounted on a seat member disposed in a projecting manner on a mounting member mounted on a mounted member. Is inserted into an attachment hole formed in the attached member from the front side to the back side in the insertion direction of the attached member, and is an attachment structure with a clip that attaches the attachment member to the attachment member in a detachable manner,
The resin-made clip main body includes a pair of seating surface engaging pieces that sandwich the seating surface member formed on the inside, and a latch that is formed on the outer side and that engages with the mounting hole of the mounted member. And a pair of mounting locking pieces formed with protrusions on the shoulders and elastically applied in the expanding direction, and the pair of seating surface engaging parts between the seating surface members. An integrated means for integrating the two in the pulling direction with respect to the acting force in the relative pulling direction between the two is provided, and the pair of mounting locking pieces have leg pieces facing backward in the insertion direction. It is formed to extend, and the rear end in the insertion direction of the extended leg piece is formed to be a rear position from the rear end in the insertion direction of the seating surface engaging piece,
The seat member is configured to make a difference in contact state between the leg piece of the clip main body and the seat member when the clip structure is removed from the attached member. There are a plurality of types of surface members and second seating surface members, and the first seating surface member and the second seating surface member are different when the clip structure is removed from the mounted member due to the difference in the corresponding contact state. The drag generated in the clip body is different,
By attaching the clip main body by selecting the first seating surface member or the second seating surface member, the holding load of the mounting state of the mounting member to the mounted member can be varied.

According to the first aspect of the invention, when the clip structure using the first seat member is removed from the attached member and when the clip structure using the second seat member is removed from the attached member. Then, a difference arises in the contact state to the seat surface member of the leg piece of a clip main body. Therefore, a difference occurs in the deformation state of the clip main body, and a difference in drag generated in the clip main body also occurs. Therefore, a difference is generated in a force necessary for removing the clip structure from the attached member. Therefore, the holding load of the attachment state with respect to the to-be-attached member of an attachment member can be varied by selecting and attaching a clip main body to a 1st seat surface member or a 2nd seat surface member.
In addition, the seat surface engaging part piece of the clip main body is provided with an integration means for integrating both in the pulling direction with respect to the acting force in the relative pulling direction between the seat surface member, Since the holding load on the attachment member of the clip body is set larger than the holding load on the attachment member of the clip body, it is not necessary to consider that the clip body is detached from the attachment member.

Next, a second invention of the present invention is a mounting structure using a clip according to the first invention,
The integration means for integrating the seat surface engaging part piece and the seat surface member in the pulling direction is engaged with an engagement hole formed in the seat surface member and the engagement hole. It is an engagement protrusion provided in the said seat surface engagement part piece to do.
According to the second aspect of the present invention, the integration means for integrating both the seating surface engaging portion piece and the seating surface member in the drawing direction is provided in the engagement hole formed in the seating surface member. A simple structure can be realized by inserting and engaging the engaging protrusion provided on the joint piece.

Next, a third invention of the present invention is a mounting structure with a clip according to the first invention or the second invention,
The first seating member and the second seating surface have the same thickness at the portion sandwiched between the seating surface engaging portion pieces of the clip body, but have different thicknesses at the rear position in the insertion direction thereafter. A first seating surface member is attached to the first leg of the attachment locking piece in a state where the clip structure is inserted into the attachment hole and attached. When the thickness of the second seating surface member is set so as not to contact the seating surface member, the thickness of the second seating surface member is set so that the leg piece of the mounting locking piece contacts the second seating surface member. When the seat member has such a thickness that the leg piece of the mounting locking piece comes into contact with the first seating surface member, the second seating member has the leg piece of the mounting locking piece as the second piece. It is characterized by having a thickness that makes contact with the seat member more strongly than contact with the first seat member.

According to the third aspect, when the first seat member is used, the leg piece of the clip body does not contact the first seat member, and the second seat member is used. The clip body leg piece is in contact with the second seat surface member, and the clip body leg piece is used both when the first seat surface member is used and when the second seat surface member is used. The second configuration in which the leg piece is in contact with the seat member more strongly in the case of using the second seat member than in the case of using the first seat member. Can be taken.
According to this 1st structure, in the state which attached the attachment member to the to-be-attached member using the 1st seat surface member, the leg piece of a clip main body has not contact | abutted to the seat surface member. The holding load of the mounting member on the mounted member in this case corresponds to a force necessary for bending the mounting locking piece with the base of the locking piece as a fulcrum to remove the locking shoulder from the mounting hole. On the other hand, in a state where the attachment member is attached to the attached member using the second seat member, the leg pieces of the clip body are in contact with the seat member. In this case, the holding load of the mounting member with respect to the mounted member is determined by the location where the locking shoulder of the mounting locking piece is locked to the mounting member on the back side of the mounting member and the location where the leg piece abuts the seat member. This corresponds to the force required to bend in the opposite direction and remove the locking shoulder from the mounting hole.
Compared with the case where the mounting locking piece is bent at the base of the locking piece and the locking shoulder is removed from the mounting hole, the mounting locking piece is engaged with the mounted member on the back side of the mounted member. In order to bend in the reverse direction and remove the locking shoulder from the mounting hole at the place where the stop piece and the leg piece abut against the seat member, a greater force is required.
Therefore, when the second seat member is used as the seat member, the holding load is larger than when the first seat member is used as the seat member. The holding load of the attachment state with respect to the to-be-attached member of a member can be varied.
In addition, the seat surface engaging part piece of the clip main body is provided with an integration means for integrating both in the pulling direction with respect to the acting force in the relative pulling direction between the seat surface member, Since the holding load on the attachment member of the clip body is set larger than the holding load on the attachment member of the clip body, it is not necessary to consider that the clip body is detached from the attachment member.
According to the second configuration, the leg piece of the clip main body is in contact with the seating surface member regardless of whether the first mounting member is used or the second seating surface member is used. In this case, the holding load of the mounting member on the mounted member is such that the mounting locking piece is locked to the mounting member on the back side of the mounting member and the leg piece is applied to the seating surface member. This is equivalent to the force required to bend in the opposite direction at the contact point and remove the locking shoulder from the mounting hole. Here, when the second mounting member is used, the leg piece is in contact with the seating surface member more strongly than when the first mounting member is used, so the second seating member is used. The holding load is larger when Therefore, also by the second configuration, the holding load of the mounting state of the mounting member with respect to the mounted member can be varied by selecting the seat member.

Next, a fourth invention of the present invention is a mounting structure using a clip according to the third invention,
The thickness of the portion of the first seating surface member that is sandwiched between the seating surface engaging portion pieces of the clip main body and the thickness of the rear position in the subsequent insertion direction are the same.
According to the fourth aspect of the invention, since the first seat member can make the seat member uniform in thickness, the seat member can be formed easily.

Next, a fifth invention of the present invention is a mounting structure by a clip according to the third invention or the fourth invention,
The thickness of the second seating surface member in the insertion direction rearward position is formed in a rib shape or a surface shape.
According to the fifth aspect of the present invention, the difference between the first seating surface member and the second seating surface member can be only the presence or absence of the rib shape or the surface shape. Changes can be realized.

Next, a sixth invention of the present invention is a mounting structure using a clip according to the first invention or the second invention,
The seat surface member has a first seat surface member in which an escape hole is formed at a rear position in the insertion direction after the portion sandwiched by the seat surface engaging portion piece of the clip body, and an escape hole is formed at the position. A second seating surface member not provided,
When the clip structure is removed from the mounted member, the leg piece of the clip body is accommodated in the relief hole of the first seat surface member in the first seat surface member, and the clip body is disposed in the second seat surface member. The leg piece is in contact with the outer surface of the second seat member.

According to the sixth aspect of the present invention, when the clip structure using the first seat member is removed from the member to be attached, the leg pieces of the clip body are accommodated in the relief holes of the seat member. Therefore, if the leg piece does not abut against the seat member, no drag is generated on the leg piece, and even when the leg piece abuts against the seat member, the leg piece is released by the relief hole, compared to the case where there is no escape hole. Therefore, there is little deformation of the leg pieces, and the drag generated on the mounting locking pieces is also small.
On the other hand, when the clip structure using the second seat member is removed from the attached member, the leg pieces of the clip body abut on the outer surface of the seat member. Therefore, when the second seating surface member is used, the leg piece is greatly deformed and the drag generated on the attachment locking piece is larger than when the first seating surface member is used.
Therefore, compared with the case where the first seating surface member is used, the force required for the removal becomes larger when the second seating surface member is used. Accordingly, by selecting whether the seat member to which the clip body is attached is the first seat member or the second seat member, the holding load of the attachment member to the attached member can be varied. it can.

Next, a seventh invention of the present invention is a mounting structure by a clip according to the sixth invention,
The escape hole is a through hole, and a protrusion is formed inside a pair of leg pieces of the clip body. When the clip structure is removed from the attached member, The protrusion of the leg of the clip body fits in the relief hole of the first seat member, and the protrusion of the leg of the clip body contacts the outer surface of the second seat member in the second seat member. It is characterized by touching.

According to the seventh aspect of the present invention, when the clip structure using the first seating surface member is removed from the attached member, the protrusions of the leg pieces of the clip body are formed in the relief holes that penetrate the seating surface member. It will fit. Therefore, if the leg piece does not abut against the seat member, no drag is generated on the leg piece, and even when the leg piece abuts against the seat member, there is no escape hole because the protrusion of the leg piece is released by the escape hole. The deformation of the leg piece is less than that of the case, and the drag generated on the mounting locking piece is small.
On the other hand, when the clip structure using the second seat member is removed from the attached member, the protrusions of the leg pieces of the clip body abut on the outer surface of the seat member. Therefore, when the second seating surface member is used, the leg piece of the clip body has a greater deformation of the leg piece than the case where the first seating surface member is used, and the drag generated on the mounting locking piece is larger. .
Therefore, compared with the case where the first seat member is used, the force required when the clip structure is removed from the attached member is larger when the second seat member is used. Accordingly, by selecting whether the seat member to which the clip body is attached is the first seat member or the second seat member, the holding load of the attachment member to the attached member can be varied. it can.
In addition, even if the entire leg piece is not released by the escape hole, the protrusion of the leg piece is released by the escape hole, so that the contact state of the leg piece to the seat member is made different, and the holding load is made different. Can do. Therefore, the escape hole may be formed only in the portion corresponding to the protrusion.

Next, an eighth invention of the present invention is a mounting structure using a clip according to the first invention,
In the seat member, an escape hole penetrating the seat member is formed on one side at the rear side in the insertion direction from the portion sandwiched between the seat engaging portions of the clip body, and a pair of legs of the clip body is formed. A protrusion is formed on one side of the direction perpendicular to the spreading direction on the inside of the piece,
The seat surface member includes a first seat surface member capable of attaching the clip body in a direction in which the protrusion of the leg piece corresponds to the position of the relief hole of the seat surface member, and the protrusion of the leg piece by inverting the clip body. The portion also serves as a second seating surface member that can be mounted in an orientation that does not correspond to the position of the relief hole of the seating surface member,
When the clip structure is removed from the mounted member, when used as the first seat member, the protrusions of the leg pieces of the clip body are accommodated in the relief holes of the seat member, and the second seat surface When used as a member, the protrusions of the leg pieces of the clip body are in contact with the outer surface of the seat member.

According to the eighth invention, when the clip body is attached in a direction in which the protrusion of the leg piece corresponds to the position of the relief hole of the seat member, and the seat member is used as the first seat member, When the clip structure is removed from the member to be attached, the protrusions of the leg pieces of the clip body are accommodated in the relief holes of the seat member. Therefore, if the leg piece does not contact the seat member, no drag is generated on the leg piece, and even when the leg piece contacts the seat member, the protrusion of the leg piece is released by the escape hole, so there is no escape hole. The deformation of the leg pieces is less than that of the case, and the drag generated on the attachment locking pieces is also small.
On the other hand, when the clip body is attached to the seat member so that the protrusion of the leg piece does not correspond to the position of the relief hole of the seat member, and the seat member is used as the second seat member, the clip structure When pulling out from the member to be attached, the protrusions of the leg pieces of the clip body come into contact with the outer surface of the seat member. Therefore, when it is used as the second seat member, the deformation of the leg piece is larger and the drag generated on the attachment locking piece is larger than when the projection of the leg piece of the clip body is released by the escape hole. Therefore, compared with the case where the seat member is used as the first seat member, the force required when the clip structure is removed from the attached member is greater when the seat member is used as the second seat member. Becomes larger. Therefore, the attachment state of the attachment member with respect to the attached member is maintained by selecting the direction in which the clip body is attached to the seat member and causing the seat member to function as the first seat member or the second seat member. The load can be varied.

According to each invention of the present invention, the following effects can be obtained.
First, according to the first invention described above, two types of seating members are used in which a difference in contact state of the leg pieces of the clip main body with the seating member when the clip structure is removed from the attached member is used. By doing so, the drag generated in the clip body when the mounting member is removed from the mounted member can be varied, and the holding load of the mounting member to the mounted member can be varied. Therefore, a plurality of types of clips prepared according to the holding load can be combined into one. Thereby, the sharing of the clip can be achieved and the cost can be reduced. Cost reductions range from clip manufacturing, supply management, and mounting operations.
Next, according to the above-mentioned second invention, it is possible to prevent the clip from coming off the seat member with a simple structure.

Next, according to the above-described third invention, by changing the thickness of the seat member formed on the mounting member, even when the same type of clip is used, the drag force when removing the mounting member from the mounted member is increased. The holding load can be varied by changing. Therefore, by changing the thickness of the seat member, a plurality of types of clips prepared with different product numbers can be combined into one according to the holding load. Thereby, standardization of a clip progresses and cost can be reduced. Cost reductions range from clip manufacturing, supply management, and mounting operations.
Next, according to the fourth aspect described above, the thickness of the first seating surface member can be made uniform, so that the seating surface member can be formed easily.
Next, according to the fifth aspect described above, the difference between the first seating surface member and the second seating surface member can be only the presence or absence of the rib shape or the surface shape, so that the seating surface member is slightly changed. The holding load can be changed by the work.

Next, according to the above-described sixth invention, the first seat member in which the escape hole for allowing the leg piece to escape is formed at a position corresponding to the leg piece, and the second seat in which there is no escape hole and the leg piece cannot be escaped. By using the surface member, when the clip structure is removed from the mounted member, a difference occurs in the contact state of the leg piece of the clip body with the seat surface member. , There will be a difference in drag at the time of removal. Therefore, by selecting whether the seat member to which the clip body is attached is the first seat member or the second seat member, the holding load of the attachment member to the attached member can be varied. it can.
Next, according to the seventh invention described above, the first seat member in which the escape hole for allowing the projection to escape is formed at a position corresponding to the projection of the leg piece, and the projection of the leg piece without the escape hole. By using the second seat member that cannot be escaped, when the clip structure is removed from the attached member, a difference occurs in the contact state of the leg piece of the clip body with the seat member. There is a difference in the drag that occurs, and there is a difference in the drag when pulling out. Therefore, by selecting whether the seat member to which the clip body is attached is the first seat member or the second seat member, the holding load of the attachment member to the attached member can be varied. it can.
Next, according to the above-mentioned eighth invention, the structure in which the protrusion of the leg piece is released by the escape hole of the seat surface member by reversing the direction of attaching the clip main body and the protrusion of the leg piece not corresponding to the escape hole. By using a clip body and a seating surface member that can take a structure that does not allow the clip to be released, when the clip structure is removed from the attached member, the contact state of the leg pieces of the clip body to the seating surface member is changed. As a result, a difference occurs in the drag generated in the mounting locking piece, and a difference occurs in the drag force during removal. Therefore, by selecting the direction in which the clip body is attached to the seat member and causing the seat member to function as the first seat member or the second seat member, the holding load of the attachment member attached to the attached member Can be different.

The insertion load in this case is that the pair of mounting locking pieces 14 are bent in the opposite directions at the position where the locking shoulder 16 contacts the mounting hole 32 and the position where the leg piece 18 contacts the rib 26, and the locking shoulder 16 is mounted. This corresponds to the force required to compress and shrink to a width that can pass through the hole 32.
The pair of mounting locking pieces 14 are bent more than the force required to deflect the locking shoulders 16 through the mounting holes 32 by bending the pair of mounting locking pieces 14 with the locking piece base 15 as a fulcrum. The force required to bend in the opposite direction between the position where the locking shoulder 16 abuts against the mounting hole 32 and the position where the leg piece 18 abuts against the rib 26 so that the locking shoulder 16 can pass through the mounting hole 32 is compressed. Therefore, the mounting load using the second seat member 28 is larger than the mounting load using the first seat member 27.

FIG. 6 shows how the clip structure 11 in which the resin clip body 10 is attached to the first seat member 27 from the attachment hole 32 of the attachment member 30 in the attachment structure according to the first embodiment of the present invention. It is a fragmentary sectional view showing the state just before ending.
FIG. 7 shows how the clip structure 11 in which the resin clip body 10 is attached to the second seat member 28 from the attachment hole 32 of the attachment member 30 in the attachment structure according to the first embodiment of the present invention. It is a fragmentary sectional view showing the state just before ending.
When the attachment member is attached to the attached member 30 using the first seat member 27, the leg piece 18 of the clip body 10 is not in contact with the first seat member 27. Accordingly, the holding load of the mounting member on the mounted member 30 corresponds to a force required to bend the pair of mounting locking pieces 14 with the locking piece base 15 as a fulcrum and remove the locking shoulder 16 from the mounting hole 32. To do. In this embodiment, as shown in FIG. 6, the tip end of the leg piece 18 abuts on the first mounting member 27 immediately before the clip structure 11 is detached from the mounted member 30. Therefore, the actual holding load is slightly increased from the force required to bend the mounting locking piece 14 with the locking piece base 15 as a fulcrum and remove the locking shoulder 16 from the mounting hole 32.
On the other hand, when the attachment member is attached to the attached member 30 using the second seat member 28, the leg piece 18 of the clip body 10 is in contact with the second seat member 28. Therefore, the holding load of the mounting member to the mounted member 30 is such that the pair of mounting locking pieces 14, the positions where the locking shoulder 16 locks the mounted member 30 on the back surface side 36 of the mounted member 30, and the leg pieces. This is equivalent to the force required to bend the locking shoulder 16 from the mounting hole 32 by bending it in the reverse direction at the point where 18 contacts the second seat member 28.
Compared to the case where the pair of mounting locking pieces 14 is bent with the locking piece shoulder 15 as a fulcrum and the locking shoulder 16 is removed from the mounting hole 32, the pair of mounting locking pieces 14 are attached to the locking shoulder 16. In order to remove the locking shoulder 16 from the mounting hole 32 by bending in the opposite direction at the position where the back surface side 36 of the member 30 is locked to the mounted member 30 and the position where the leg piece 18 contacts the second seating surface member 28. Need more power.
Therefore, the holding load becomes larger when the second seat member 28 is used as the seat member 22 than when the first seat member 27 is used as the seat member 22. By selecting this, the holding load of the mounting member on the mounted member 30 can be varied.
The clip main body 10 and the first seating surface member 27 or the second seating surface member 28 have an engaging protrusion 13 formed at the tip of the seating surface engaging portion piece 12 of the clip main body 10 as the first seat. The engaging member 24 is engaged with the engaging hole 24 formed in the surface member 27 or the second seating surface member 28, and both are integrated in the pulling direction with respect to the acting force in the relative pulling direction therebetween. The holding load for the attachment member of the main body 10 is set to be larger than the holding load for the attachment member 30 of the clip main body 10. Therefore, the clip body 10 is not detached from the attachment member before the clip body 10 is detached from the attached member 30.

FIG. 8 is a diagram comparing the thicknesses of the first seat member 27 and the second seat member 28 in the mounting structure according to the first embodiment of the present invention.
FIG. 9 shows a result of comparative measurement of holding load when the first seat member 27 is used and when the second seat member 28 is used in the mounting structure according to the first embodiment of the present invention. FIG. As shown in FIG. 9, by changing the plate thickness of the seat member 22, the holding load when the attachment member is attached to the attachment member 30 using the same clip body 10 can be changed. In this example, by providing ribs on the seat member to increase the thickness, the holding load could be 2.3 times compared to the case where no ribs were provided. On the other hand, the insertion load was 1.7 times that of the case where no rib was provided.
The insertion resistance of the clip body 10 is affected by the angle θ1 formed by the inclined surface in the insertion direction of the locking shoulder 16 shown in FIG. On the other hand, the removal resistance is affected by the angle θ2 formed by the inclined surface on the rear side in the insertion direction of the locking shoulder 16 and the side surface of the mounting hole 32 shown in FIG. Here, the smaller the angle, the smaller the resistance. In the clip body 10, θ1 is set to be smaller than θ2, and the insertion load is suppressed to be lower than the holding load.

  The first embodiment of the present invention has been described above, but the present invention can be implemented in various other forms within the scope of the idea of the present invention. For example, in the first embodiment, the rib of the second seat member is provided to increase the thickness of the portion of the seat member that contacts the leg piece, but the seat member itself can be increased in thickness. Further, in the first embodiment, the range in which the thickness of the seat member is increased is the entire range below it including the position where the leg piece abuts, but the range in which the thickness is increased is limited to the portion where the leg piece abuts. You can also.

FIG. 10 shows a clip body 10a used in a modified embodiment of the first embodiment of the present invention. Compared with the clip body 10 used in the above embodiment, the locking shoulder 16 formed outwardly projecting on the mounting locking piece 12 has a straight portion 17.
In the mounting structure using the clip body 10a, since the locking shoulder 16 has the straight portion 17, the stroke on which the maximum load is applied during the extraction becomes longer, and the removal is performed compared to the mounting structure using the clip body 10 without the straight portion. Therefore, it is necessary to apply the maximum load for a longer time. Therefore, there is a feature that it is difficult to come off against an impact load.
The point that the clip main body 10a can be used for the first seating surface member 27 and the second seating surface member 28 to correspond to different holding loads is the same as when the clip main body 10 is used. Further, since the clip body 10a is common to the clip body 10 except that the locking shoulder 16 has the straight portion 17, detailed description thereof is omitted.
Note that the clip body 10a requires a longer maximum load to be removed, and the feature that the clip body 10a is less likely to come off against an impact load is independent of being able to handle different holding loads. ing.
Therefore, the use of the clip main body 10a is not limited to the present invention, and can be widely used by taking advantage of the feature that the clip main body 10a is not easily detached from the impact load.

In the clip main body 10a, the width between the pair of clamping surfaces 19 of the seating surface joint piece 12 that clamps the seating surface member 22 from the side surface gradually increases from the rear of the clip main body 10a in the insertion direction to the front of the insertion direction. There is a feature that is.
Then, in relation to the seat surface member 22, the width a between the pair of sandwiching surfaces 19 at the rear of the clip body 10 a in the insertion direction is the thickness of the seat surface member 22 sandwiched by the pair of seat surface engaging pieces 12. It is set smaller than b. Further, the width c between the pair of clamping surfaces 19 in the insertion direction front of the clip body 10a is set to be larger than the thickness b of the seating surface member 22 sandwiched between the pair of seating surface engaging pieces 12. That is, in FIG. 10, a <b <c.
Therefore, in a state where the clip main body 10a is attached to the seat surface member 22, the width between the sandwiching surfaces 19 of the pair of seat surface system joining pieces 12 is rearward in the insertion direction of the clip main body 10a. Expands to elastic thickness by elastic deformation. Therefore, since the seating surface member 22 is clamped by the both clamping surfaces 19 of the pair of seating surface engaging portion pieces 12 in a state where the elastic force is applied, the attachment of the clip body 10a to the seating surface member 22 is stabilized. .

Next, a second embodiment of the present invention will be described.
FIG. 11 is an external perspective view of the resin clip body 110 used in the second embodiment of the present invention in a free state. The clip main body 110 is made of resin and has a pair of seating surface engaging portion pieces 114 formed on the inner side and a pair of attachment locking pieces 120 formed on the outer side.
An engaging protrusion 116 is provided at the tip of the seating surface engaging piece 114, and a locking shoulder 125 is formed on the mounting locking piece 120 so as to protrude outward. A straight surface 126 connected to the upper portion is formed. The straight surface 126 extends in a substantially vertical direction when the clip body 110 is in a free state.
Further, a leg piece 128 is formed on the mounting locking piece 120 so as to extend rearward in the direction in which the clip body 110 is inserted, following the engaging slope 124, and the rear end of the leg piece 128 in the insertion direction is engaged with the seat surface. It is set as the structure which becomes a back position rather than the rear end of the insertion direction of the joining piece 114. FIG. A leg leg 127 is formed on the leg piece 128 so as to extend outward from the rear end in the insertion direction and outward in the spreading direction. The leg piece 128 is provided at the center in the depth direction inside the rear end in the insertion direction. Shaped projections 129 are formed to face each other.

FIG. 12 is an external perspective view of the first seat member 133 used in the second embodiment, and FIG. 13 is an external perspective view of the second seat member 134 used in the second embodiment.
The first seat member 133 shown in FIG. 12 is disposed in a projecting state on the mounting member 130 and is formed integrally with the mounting member 130, and reinforcing members 135 are disposed on both sides in the width direction to be reinforced. ing. A guide groove 138 that guides the seating surface engaging piece 114 when the clip body 110 is attached to the first seating surface member 133 is formed at the distal end of the first seating surface member 133.
Following the guide groove 138, an engagement hole 136 for engaging the engagement protrusion 116 of the seat surface engagement portion piece 114 of the clip body 110 is formed slightly above the center of the first seat surface member 133. ing. An escape hole 140 for allowing the leg piece 128 of the clip main body 110 to escape is formed in the center in the width direction of the first seating surface member 133 below the engagement hole 136. The second seating surface member 134 shown in FIG. 13 has the same configuration as the first seating surface member 133 except that the escape hole 140 is not formed.

FIG. 14 shows a state in which the clip structure 112A in which the resin clip body 110 is attached to the first seat member 133 disposed in a projecting manner on the attachment member 130 in the second embodiment is attached to the attachment member 150. FIG.
The clip body 110 is attached to the distal end portion of the first seating surface member 133 with the first seating surface member 133 sandwiched between the pair of seating surface engaging portion pieces 114. It should be noted that the pair of seating surface engaging portions 114 are set to be narrower than the thickness of the first seating surface member 133 to be sandwiched in the free state, and inward in the state of sandwiching the first seating surface member 133. The elasticity is given.
Then, the engaging protrusion 116 formed at the tip of the seating surface engaging part piece 114 is engaged with the engaging hole 136 formed in the first seating surface member 133, and the seating surface engaging part piece 114 and the first Both of the seating surface members 133 are integrated in the drawing direction with respect to the acting force in the relative drawing direction.
The attachment member 130 is attached to the attachment member 150 by inserting the clip structure 112 </ b> A into the attachment hole 152 from the front surface side 154 to the back surface side 156 of the attachment member 150.
The attachment locking piece 120 is formed in a wider state than the opening width of the attachment hole 152 in the free state. Therefore, the attachment to the attachment hole 152 is attached as a state in which the attachment locking piece 120 is elastically deformed inward, and in the attachment state, the attachment locking piece 120 is fitted with a resilient force in the expanding direction. Is in a state.

  FIG. 15 shows a state in which the clip structure 112B in which the resin clip body 110 is attached to the second seat member 134 disposed in a protruding state on the attachment member 130 in the second embodiment is attached to the attachment member 150. FIG. The difference between the clip structure 112 </ b> B and the clip structure 112 </ b> A is that the escape hole 140 is not formed in the second seating surface member 134. The clip body 110 is the same as that attached to the first seat member 133.

Here, the insertion load when the first seat member 133 is used and when the second seat member 134 is used will be described.
When the clip structure 112 </ b> A is inserted into the attached member 150, the protrusion 129 at the tip of the leg piece 128 of the clip main body 110 enters the escape hole 140 of the first seating surface member 133 and is thus released. The deformation is small, and the drag generated on the mounting locking piece 120 is small.
The insertion load in this case is such that the clip structure 112A is pressed against the mounting hole 152 and the pair of mounting locking pieces 120 are bent with the locking piece base 122 as a fulcrum, so that the locking shoulder 125 can pass through the mounting hole 152. It is roughly equivalent to the force required to compress. At the end of the insertion, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the projection 129 and is slightly deformed, but the effect is small.

  On the other hand, when the clip structure 112B is inserted into the attached member 150, the second seating surface member 134 does not have the escape hole 140, and the protrusion 129 at the tip of the leg piece 128 of the clip body 110 is inserted during the insertion. It abuts on the second seat member 134. Therefore, since it is necessary to insert the leg piece 128 while deforming it, the drag force generated in the attachment locking piece 120 becomes larger than when the first seating surface member 133 is used. In this case, the insertion load is such that the clip structure 112B is pressed against the mounting hole 152, the pair of mounting locking pieces 120 are where the locking shoulder 125 abuts the mounting hole 152, and the leg piece 128 is the second seating surface member. This is equivalent to the force required to bend in the opposite direction at the place where it abuts against 134 and to be compressed so that the locking shoulder 125 can pass through the mounting hole 152. Therefore, the insertion load becomes larger when the second seat member 134 is used.

Next, the removal load when the first seat member 133 is used and when the second seat member 134 is used will be described.
FIG. 16 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112A using the first seat member 133 from the attached member 150 in the second embodiment.
When the clip structure 112A is removed from the attached member 150, the attachment locking piece 120 is bent with the locking piece base 122 as a fulcrum so that the inclined surface 124 and the straight surface 126 are close to each other as the extraction proceeds. The leg pieces 128 of the locking pieces 120 are close to each other, and the leg pieces 128 come into contact with the first seat member 133. However, since the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, the leg piece 128 comes into contact with the first seating surface member 133 to be attached and locked. The drag generated by the piece 120 is smaller than when the escape hole 140 is not formed.
In this case, the removal load is such that the clip structure 112A is pulled away from the mounting hole 152, the pair of mounting locking pieces 120 are bent using the locking piece base 122 as a fulcrum, and the locking shoulder 125 becomes the mounting hole 152. It is almost equivalent to the force required to compress the width to pass through. At the end of the extraction, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the protrusion 129 and slightly deforms, but the effect is small.

FIG. 17 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112B using the second seat member 134 from the attached member 150 in the second embodiment.
When the second seating surface member 134 is used as the seating surface member 132, the mounting locking piece 120 is bent with the locking piece base portion 122 serving as a fulcrum so that the inclined surface 124 and the straight surface 126 approach each other as the removal proceeds. When the leg pieces 128 of the mounting locking pieces 120 are close to each other and the protrusions 129 at the tips of the leg pieces 128 are in contact with the second seating surface member 134, and the first seating surface member 133 is used. The contact state of the clip body 10 with the seat member 134 is different.
Therefore, the deformation of the leg piece 128 is larger than when the protrusion 129 at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, and the attachment locking piece 120 is generated by the deformation of the leg piece 128. The drag is greater than when the protrusions 129 of the leg pieces 128 are released by the escape holes 140. In this case, the removal load is such that the clip structure 112B is pulled away from the mounting hole 152, and the pair of mounting locking pieces 120 are brought into contact with the mounting holes 152 and the protrusions 129 of the leg pieces 128. Corresponds to a force required to bend in the opposite direction at a position where it abuts against the second seat member 134 so that the locking shoulder 125 can be pushed and shrunk to a width that allows it to pass through the mounting hole 152.

Therefore, when the clip structures 112 </ b> A and 112 </ b> B are removed from the attached member 150, the first seating surface member 133 and the second seating surface member 133 are different in the contact state of the leg piece 128 of the clip body 110 with the seating surface member 132. By using the seat member 134, it is possible to vary the drag generated when the mounting member 130 is removed from the mounted member 150 using the same clip body 110, and the mounting state of the mounting member 130 with respect to the mounted member 150 The holding load can be made different.
In addition, you may implement in the aspect which forms the 1st seat surface member 133 and the 2nd seat surface member 134 in the same attachment member 130, and there exists only a 1st seat surface member in a certain attachment member. It is also possible to implement in a mode in which only the second seat member is formed on another mounting member.

In the second embodiment, the protruding portion 129 is formed at the center in the depth direction inside the tip of the leg piece 128. However, the protruding portion 129 is divided into two portions in the depth direction at the tip of the leg piece 128. The first seating surface member 133 may be provided with two relief holes 140 corresponding to the depth direction.
In the second embodiment, a protrusion 129 is formed in the center in the depth direction inside the tip of the leg piece 128, and a relief hole 140 having a width into which the protrusion 129 enters is provided in the first seat surface member 133. The protrusion 129 is not essential. Without providing the protrusions 129, it is also possible to make the inside of the tip end of the leg piece 128 thick in the depth direction of the leg piece 128 and provide the escape hole 140 with a width that allows the whole leg piece 128 to enter. The escape hole 140 is not limited to the through hole, and the escape hole 140 may be provided as a recess on both surfaces of the first seat member 133.
In the second embodiment, the thickness of the position where the leg piece 128 of the clip main body 110 abuts on the second seating surface member 134 is the same as the thickness at the position where the seating surface engaging portion 114 engages. The thickness at the position where the piece 128 abuts may be greater than the thickness at the position where the seat surface engaging portion piece 114 engages, and a protrusion may be provided on the second seat surface member 134 side at this position. good.

Finally, a third embodiment of the present invention will be described.
FIG. 18 is an external perspective view of a resin clip body 110A used in the third embodiment of the present invention in a free state. The basic structure of the clip body 110A is the same as that of the clip body 110 used in the second embodiment. Therefore, a detailed description is omitted, and the difference from the clip body 110 will be described.
The difference between the clip body 110 </ b> A and the clip body 110 is in the position and shape of the protrusion 129 formed at the tip of the leg piece 128. In the clip body 110 </ b> A, the protrusion 129 is formed at a position closer to one side in the depth direction of the clip body 110 </ b> A with a slightly narrower width than the clip body 110.

FIG. 19 is an external perspective view of the seat member 132A used in the third embodiment. The seat member 132A is provided on the attachment member 130 in a projecting state and is formed integrally with the attachment member 130, and reinforcement members 135 are provided on both sides for reinforcement. A guide groove 138 for guiding the seat surface engaging piece 114 when the clip body 110A is attached to the seat surface member 132A is formed at the tip of the seat surface member 132A.
Following the guide groove 138, an engagement hole 136 for engaging the engagement protrusion 116 of the seat surface engagement portion piece 114 of the clip body 110A is formed slightly above the center of the seat surface member 132A. An escape hole 140 is formed so as to allow the projection 129 of the leg piece 128 of the clip body 110A to escape toward one side in the width direction of the seat surface member 132A below the engagement hole 136.
In the third embodiment, by changing the direction of attaching 110A to the seat member 132A, the corresponding state of the relief holes 140 of the protrusions 129 and 132A of 110A is changed, so that the seat member 132A has the first seat surface. The role of both the member 133 and the second seat member 134 can be provided.

20 shows a state in which the seat surface member 132A has the role of the first seat surface member 133 in the third embodiment, and the clip structure 112C in which the clip body 110A is attached to the seat surface member 132A is attached to the attached member 150. FIG. In the clip structure 112C, the protrusions 129 of the leg pieces 128 of the clip main body 110A and the relief holes 140 of the seating surface member 132A have corresponding orientations. In FIG. 20, the protrusion 129 and the relief hole 140 of the leg piece 128 are on the front side of the cross section.
FIG. 21 shows a state in which the seat member 132A has the role of the second seat member 134 in the third embodiment, and the clip structure 112D in which the clip body 110A is attached to the seat member 132A is attached to the attached member 150. FIG. In the clip structure 112D, the protrusions 129 of the leg pieces 128 of the clip main body 110A and the escape holes 140 of the seating surface member 132A are not aligned. In FIG. 21, the protrusion 129 of the leg piece 128 is on the front side of the cross section, and the relief hole 140 is on the rear side of the cross section.
22A is a cross-sectional view of the clip structure 112C at the position AA in FIG. 20, and FIG. 22B is a cross-sectional view of the clip structure 112D at the position BB in FIG.

In the clip structures 112C and 112D, the clip main body 110A is attached to the distal end portion of the seating surface member 132A with the seating surface member 132A sandwiched between the pair of seating surface engaging portion pieces 114. It should be noted that the pair of seating surface engaging pieces 114 are spaced at a distance narrower than the thickness of the seating surface member 132A to be sandwiched in the free state, and an inward resilient force is imparted in the state of sandwiching the seating surface member 132A. It has become a state.
Then, the engaging protrusion 116 formed at the tip of the seating surface engaging piece 114 is engaged with the engaging hole 136 formed in the seating surface member 132A, and the seating surface engaging piece 114 and the seating surface member 132A are engaged. Both are integrated in the drawing direction with respect to the acting force in the relative drawing direction.
The attachment member 130 is attached to the attachment member 150 by inserting the clip structure 112 </ b> C or 112 </ b> D into the attachment hole 152 from the surface side 154 of the attachment member 150.
The attachment locking piece 120 is formed to be wider than the opening width of the attachment hole 152 in the free state. Therefore, the attachment to the attachment hole 152 is attached as a state in which the attachment locking piece 120 is elastically deformed inward, and in the attachment state, the attachment locking piece 120 is fitted with a resilient force in the expanding direction. Is in a state.

Here, the insertion load when the seat member 132A is used as the first seat member 133 and the second seat member 134 will be described.
As shown in FIG. 22A, in the clip structure 112C, the protrusions 129 of the leg pieces 128 of the clip body 110A correspond to the escape holes 140 of the seat member 132A. Therefore, when the clip structure 112C is inserted into the attached member 150, the protrusion 129 of the clip main body 110A is released by the escape hole 140 of the seat surface member 132A, so that the leg piece 128 is hardly deformed, and the attachment locking piece 120 is inserted. The drag generated in is small.
On the other hand, as shown in FIG. 22B, in the clip structure 112D, the protrusion 129 of the leg piece 128 of the clip main body 110A does not correspond to the escape hole 140 of the seating surface member 132A. Therefore, when the clip structure 112D is inserted into the attached member 150, the protruding portion 129 of the clip main body 110A is not released by the escape hole 140 of the seating surface member 132A. Therefore, it is necessary to insert the leg piece 128 while deforming it, and the drag generated in the attachment locking piece 120 becomes larger than that in the case of 112C. Therefore, the insertion load is larger in the clip structure 112D than in the clip structure 112C.

Next, the removal load when the seat member 132A is used as the first seat member 133 and when the seat member 132A is used as the second seat member 134 will be described.
FIG. 23 is a partial sectional view showing a state in the middle of removing the clip structure 112 </ b> C in which the seat member 132 </ b> A has the role of the first seat member 133 from the attached member 150 in the third embodiment. .
FIG. 24 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112D in which the role of the second seating surface member 134 is given to the seating surface member 132A from the mounted member 150 in the third embodiment. .
25A is a cross-sectional view of the clip structure 112C at the CC position in FIG. 23, and FIG. 25B is a cross-sectional view of the clip structure 112D at the DD position in FIG.

  When the seating member 132A is used as the first seating member 133, the mounting locking piece 120 is bent so that the inclined surface 124 and the straight surface 126 come close to each other with the locking piece base 122 as a fulcrum as the removal proceeds. Thus, the leg pieces 128 of the attachment locking pieces 120 are close to each other, and the leg pieces 128 come into contact with the first seating surface member 133. However, as shown in FIG. 25 (A), the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seat surface member 133, so that the leg piece 128 becomes the first seat surface. The drag generated in the attachment locking piece 120 by abutting against the member 133 is smaller than when the leg piece 128 is not released by the escape hole 140. In this case, the removal load is pulled in the direction in which the clip structure 112C is removed from the mounting hole 152, and the pair of mounting locking pieces 120 are bent with the locking piece base 122 as a fulcrum, so that the locking shoulder 125 becomes the mounting hole 152. It is almost equivalent to the force required to compress the width to pass through. At the end of the extraction, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the protrusion 129 and slightly deforms, but the effect is small.

  On the other hand, when the seating surface member 132A is used as the second seating surface member 134, when the removal proceeds, the mounting locking piece 120 uses the locking piece base 122 as a fulcrum so that the inclined surface 124 and the straight surface 126 come close to each other. The leg pieces 128 of the mounting locking pieces 120 are close to each other. Then, the protruding portion 129 of the leg piece 128 comes into contact with a portion where the escape hole 140 of the second seating surface member 134 is not formed, and the clip main body 10 is compared with the case where the first seating surface member 133 is used. There is a difference in the state of contact with the seating surface member 134. Then, the deformation of the leg piece 128 is larger than the case where the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, and the attachment locking is achieved by the deformation of the leg piece 128. The drag force generated on the piece 120 is greater than when the protrusion 129 of the leg piece 128 is released by the escape hole 140. In this case, the removal load is such that the clip structure 112D is pulled in the direction to remove it from the mounting hole 152, the pair of mounting locking pieces 120 and the leg pieces 128 are in contact with the mounting holes 152 and the leg pieces 128. This corresponds to the force required to bend in the opposite direction at the position where it abuts against the seat member 134 so that the locking shoulder 125 can be compressed to a width that allows it to pass through the mounting hole 152.

Therefore, by changing the direction in which the clip main body 110A is attached to the seating surface member 132A, when the clip structures 112C and 112D are removed from the attached member 150, the leg pieces 128 of the clip main body 110A abut on the seating surface member 132A. A difference in state occurs, and the drag generated on the attachment locking piece 120 when the attachment member 130 is removed from the attached member 150 can be varied. Therefore, the holding load of the attachment state with respect to the to-be-attached member 150 of the attachment member 130 can be varied using the same clip main body 110A.
In the third embodiment, the escape hole 140 through which the protruding portion 129 escapes is a through hole. However, the escape hole 140 is not limited to the through hole, and the escape hole 140 may be provided as a recess on both surfaces of the seating surface member 132A.
