Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a clip holding structure.
[0002]
[Prior art]
For example, automobile side protector moldings have been attached with resin clips. In this case, the clip is not molded integrally with the molding, but a separate molding is attached to the molding, and the clip is fitted into the body in that state to fix the entire molding. . Specifically, it has a structure as shown in FIG. Briefly, a clip mounting portion 53 is formed on the inner surface of the resin molding M. One side edge of the clip attachment portion 53 is opened as an insertion port 60, and the clip 50 can be fitted therein from here. A connection edge 58 is erected from the inner surface of the molding M at the periphery except for the insertion port 60, and a seating surface 59 is projected inward along the entire edge so that the clip 50 does not come out upward. Further, the seat surface 59 opens in a circular shape as a relief opening 62 at the center, and receives the locking projection 55 of the clip 50. However, the entrance side is narrowed by the slot portion 61.
[0003]
On the other hand, the clip 50 has a rectangular substrate 51, and its size and height are set so as to be accommodated in the clip mounting portion 53 with almost no gap. In addition, a circular pressing plate 54 is provided on the upper surface of the substrate 51 via a connecting shaft portion 52, and a locking projection 55 is formed on the upper surface of the pressing plate 54. The locking projection 55 can be inserted into the mounting hole 57 drilled in the body panel B, and a pair of retaining claws 56 are formed on the side surface thereof. , That is, the molding M is fixed to the body B.
[0004]
[Problems to be solved by the invention]
However, the above conventional ones have the following problems. That is, the clip mounting portion 53 is provided with the slot portion 61 so that the clip 50 does not come out. Therefore, the function cannot be performed if the clip mounting portion 53 easily deforms the insertion port 60. For this purpose, the connection edge 58 of the clip mounting portion 53 is formed with a minimum necessary thickness so as to obtain a required strength. From such a background, a dent phenomenon called “sink H” occurs at the position corresponding to the connection edge 58 on the surface of the molding M. The phenomenon of “sink H” is caused by the pulling of the resin that occurs immediately after molding, but such a phenomenon tends to become stronger as the thickness of the connection edge 58 increases. Thus, conventionally, since it has been technically difficult to make the connection edge 58 thinner than before, the appearance quality of the molding M is often impaired by “sink H”.
[0005]
Further, even if the thickness of the connection edge 58 is minimized, some measure is desired in order to surely avoid the deformation of the clip mounting portion 53. Conventionally, the holding plate 54 is provided on the clip 50 and the seat surface 59 is sandwiched between the substrate 51 and the opening 60 is thereby prevented from expanding. However, if this is done, an extra height of the molding M is required by the thickness of the pressing plate 54, which is against the desire to reduce the molding M height.
[0006]
Further, in forming the clip attachment portion 53, as shown in FIG. 7, a punching die in both the X and Y directions has been used. In this case, since the slot portion 61 is formed in the conventional one, the relief opening 62 must be formed not by the die in the X direction but by the die in the Y direction. That is, the thickness of the punching die in the X direction cannot be ensured to be more than the height dimension from the inner surface of the molding M to the back surface of the seating surface 59. However, the two punching molds meet at the time of molding, and the punching mold in the X direction receives a pressing force from the punching mold in the Y direction. Therefore, a certain thickness is required to secure the strength against the pressing force. It is. For this reason, in order to reduce the height of the seating surface 59, there is a restriction for reasons of the mold, and as a result, the height of the molding M has become an obstacle to reduction.
[0007]
An object of the present invention is to provide a clip holding structure capable of solving the above-described conventional problems.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a structure for holding a clip for fixing a resin mounted member to the body side in a clip mounting portion projecting from the mounted member. The clip mounting portion is formed in a frame shape in which an insertion opening is opened at one side edge and is raised from a mounted member by a connection edge, and an escape opening is opened on the opposite side to the insertion opening. Is formed into a clip mounting portion that can be inserted into the clip mounting portion through the insertion port, and a substrate having a locking projection for locking to the body side is formed on the upper surface of the clip mounting portion. The hook claw protruding to the front edge of the substrate can be locked to the opening edge of the escape port when being accommodated, and sideways while holding the insertion groove on the side edge of the substrate Reinforced claws formed in a protruding manner are positioned in close contact with each other without being locked to the connection edge outside the connection edge around the insertion opening, so that the expansion deformation of the insertion opening can be regulated. it is characterized in that there.
[0009]
According to a second aspect of the present invention, in the first aspect of the present invention, in the clip mounting portion, a relief opening for allowing the locking projection to pass is continuous and uniform from the insertion port. It is characterized by being formed with a width.
[0010]
Further, the invention according to claim 3 is the one according to claim 1 or 2, wherein the clip is mounted on the surface of the substrate facing the body when the clip is accommodated in the clip attachment. The seal member is attached so as to be substantially flush with the upper surface.
[0011]
[Action and effect of the invention]
According to invention of Claim 1, a clip is accommodated in a clip attachment part through an insertion port, and, thereby, a clip is integrated with a to-be-mounted member. In this state, if the locking projection is locked to the body side, the mounted member is fixed to the body.
[0012]
When the clip is accommodated in the clip mounting portion, the reinforcing claws are positioned outside the connection edge around the insertion port to restrict the expansion of the insertion port. Therefore, even if the connection edge is set to be thin, the clip holding function is ensured, so that there is no sink problem and it is effective in maintaining the appearance quality.
[0013]
According to the second aspect of the present invention, the relief opening is formed with a substantially uniform width from the insertion opening, and does not form a slot as in the prior art. Therefore, the relief opening can be formed by the die in the insertion port direction among the die for molding the clip attachment portion. Therefore, since the die can be added to the thickness of the upper surface of the clip mounting portion compared to the conventional case, even if the height of the clip mounting portion itself is set low, the strength of the die Can be secured. Thus, as a result of suppressing the height of the clip mounting portion, it contributes to the reduction of the height of the molding.
[0014]
Furthermore, according to the invention of claim 3, since the sealing member is provided, the body side can be sealed. In this case, since the seal member does not protrude from the clip mounting portion, the height does not increase regardless of the addition of the seal member.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. FIG. 1 shows a clip mounting portion 1 provided on the inner surface of a side protector molding M (hereinafter simply referred to as a molding M) of an automobile, and a clip 2 mounted on the clip mounting portion 1.
[0016]
The molding M (a member to be mounted) is integrally formed of a synthetic resin material (for example, ABS or polypropylene), and the whole is formed in a long band shape, and the edge on the long side is inward and bent at a substantially right angle. An edge 3 is formed. And the clip attaching part 1 as shown in the figure is arranged in the appropriate place.
[0017]
The clip mounting portion 1 is configured as a substantially U-shaped frame body having an opening at one side edge (an edge on the near side in FIG. 1) in plan view. This opening is an insertion opening 4 that serves as an entrance of the clip 2, and the inside from here is a continuous opening as a relief opening 5. Further, the clip mounting portion 1 has a connection edge 8 that stands up from the inner surface of the molding M except for the insertion port 4 and the side opposite to the insertion port 4, and the side opposite to the insertion port 4 has the entire lower side. The edge is open and serves as a relief port 9. Furthermore, the upper edge of the connection edge 8 projects inward to form a seat surface 6, and this seat surface 6 is also provided on the side corresponding to the escape port 9 so as to connect both connection edges 8, And it is formed in uniform width along the perimeter. Therefore, a uniform opening width is provided from the insertion port 4 to the relief opening 5 and no conventional slot portion is provided. Furthermore, the thickness of the connection edge 8 is also set thinner than in the prior art.
[0018]
The clip 2 is also integrally formed of a synthetic resin material (for example, polyacetal or nylon). The clip 2 has a rectangular substrate 10 on its lower surface. The substrate 10 is formed with a width and thickness dimension that can be accommodated in the clip mounting portion 1 with almost no gap. That is, the substrate 10 is formed so that both side edges thereof can be slidably contacted inside the connection edge 8, and the both side edges and front edge thereof are thin-walled edges 11, and can be slidably contacted to the back side of the seat surface 6. is there. Further, a hook claw 18 which can be bent and deformed protrudes at the center of the front edge of the thin edge 11, and when the clip 2 is fitted to the normal position in the clip mounting portion 1, the opening edge of the relief port 9 It can be locked to (the outer edge of the seating surface 6).
[0019]
Further, the portion surrounded by the thin edge 11 is formed one step higher, and a front projecting edge 12 is formed on the front edge thereof, and abuts against the inner edge of the seat surface 6 of the escape port 9 to attach the clip. The insertion position of the clip 2 with respect to the part 1 is regulated. On the other hand, a rear projecting edge 13 is formed on the rear edge with the same height as the front projecting edge 12, and a seal member 14 (in this embodiment, cushion rubber is used) between the front and rear projecting edges. In addition, a seal seat surface 7 is provided for laying a through hole 21 into which the locking projection 15 is fitted in the central portion. However, in a state where the molding M is fixed to the body, the seal member 14 is attached in a slightly compressed state so as to be substantially flush with both the projecting edges and the seat surface 6.
[0020]
Further, a locking projection 15 formed in a square tube shape projects on the seal seat surface 7. The locking projection 15 is formed so as to be able to be inserted into the mounting hole 16 drilled in the body panel B, and the tip is formed in a pyramid shape in order to smoothly perform the insertion operation. In addition, a pair of retaining claws 17 are formed on the corresponding side surfaces of the locking projection 15 so as to be able to bend and deform, and can be elastically locked to the hole edge of the mounting hole 16. As a result, the whole mall M can be fixed.
[0021]
On the other hand, a pair of reinforcing claws 19 are formed on both sides of the rear end portion of the thin edge 11. Both reinforcing claws 19 extend forward while holding the insertion groove 20 between the thin edge 11, and the connection edge 8 can be introduced into the insertion groove 20 as the clip 2 is fitted. That is, the groove width of the insertion groove 20 is formed to be substantially the same as or slightly larger than the thickness of the connection edge 8, and both the reinforcing claws 19 are located in close contact with the outside of the connection edge 8, so Deformation can be regulated.
[0022]
Next, the effect of this embodiment comprised as mentioned above is demonstrated. When the molding M is fixed to the body panel B, the clip 2 is first attached to the clip attachment portion 1. The clip 2 is entered from the insertion port 4 from the direction shown in FIG. At this time, since both side edges of the thin edge 11 are in sliding contact with the inner surface of the connection edge 8, the fitting operation is performed in response to these guides. When the front projecting edge 12 is fitted to a position where it comes into contact with the inner edge of the seating surface 6 of the relief port 9, the hook claw 18 is engaged with the opening edge of the relief port 9, thereby preventing the clip 2 from coming off. Made. Further, the connection edge 8 is sandwiched in the insertion groove 20 during this time, and both the reinforcing claws 19 are located in close contact with the outside of the connection edge 8.
[0023]
Thus, when the clip 2 is attached to the molding M, the locking projection 15 is fitted into the mounting hole 16 while being pushed along the molding panel M along the body panel B. As a result, the retaining claw 17 is elastically locked to the hole edge of the mounting hole 16, so that the clip 2 is retained and the entire molding M is fixed to the body panel B.
[0024]
By the way, when some external force is applied to the molding M, the clip mounting portion 1 is deformed, and there is a risk of dissociation of the clip 2 due to the expansion deformation of the insertion port 4 associated therewith. However, in the present embodiment, when the clip 2 is fitted in the clip mounting portion 1, as described above, since both the reinforcing claws 19 are located outside the connection edge 8, the insertion opening 4 is expanded. Therefore, the clip 2 is reliably prevented from coming off. By doing so, a sufficient holding force for the clip 2 can be obtained even if the connection edge 8 is thin, so that the occurrence of the conventional “sink” is suppressed and the appearance of the molding M is maintained.
[0025]
In addition, since the deformation regulation of the clip mounting portion 1 is assured in this way, there is no need to provide a conventional pressing plate, and therefore, the problem of increasing the height of the molding M due to the thickness of the pressing plate is simultaneously provided. It will be resolved.
[0026]
Further, the clip mounting portion 1 is formed by using a punching die in the X and Y directions as shown in FIG. 1. In this embodiment, the clip mounting portion 1 is formed with a uniform opening width from the insertion port 4 to the relief opening 5. The conventional slot portion is not formed. For this reason, the punching die in the X direction can be formed only to have a thickness enough to lie below the seating surface 6 at both side edges, but a thickness from the inside to the upper surface of the seating surface 6 can be secured slightly. That is, as the punching die in the X direction, one having a convex cross section can be used. Therefore, even if the height position of the seating surface 6 is lowered, the punching die in the X direction for molding the seating surface 6 can secure a strength sufficient to resist the pressing force from the punching die in the Y direction. For this reason, the height of the clip attaching part 1 can be reduced, and thus the height of the molding M can be reduced.
[0027]
Further, in this embodiment, the sealing member 14 is provided to ensure the water tightness around the mounting hole 16, but the sealing member 14 is almost the same height as the seat surface 6, and accompanying the addition of the sealing function. There is no increase in height.
[0028]
The present invention can be modified in various ways, and the following modifications are also included in the technical scope of the present invention.
{Circle around (1)} In the present embodiment, the holding structure of the clip 2 for mounting the automobile mall M has been described. However, the mounting object is not limited to this and can be applied to a wide variety of things.
