BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for attaching and fixing a dash silencer (sheet material) to a body panel in, for example, an automobile.

[0002]

2. Description of the Related Art A sheet material called a dash silencer is attached to the interior of an automobile in order to mitigate engine noise. Conventionally, such a sheet material is attached by a clip made of synthetic resin, and a type as shown in FIG. 7 has been used.
The type shown in the figure has the first clip 30 and the second clip 30.
The clip 31 is composed of two members. The clip is usually temporarily attached to the sheet material 32 before being fixed to the body panel. That is, both clips 30 and 31 have flange portions 33 and 34 having a larger diameter than the insertion hole 38 arranged at an appropriate position of the sheet material 32, and the flange portion 33 to the tubular portion 35 are provided on the first clip 30 side. Standing upright, second
On the clip 31 side, there is an elastic leg piece 36 that can be inserted into this tubular portion 35, and this elastic leg piece 36 is engageable with a locking edge 37 formed in the tubular portion 35.

However, in the case of the above-mentioned type, since the clip is composed of two members, it has been desired to make it into a single part because of the inconvenience of handling.

Therefore, as a means for solving this, for example, the one disclosed in Japanese Utility Model Laid-Open No. 59-92213 or the one disclosed in Japanese Utility Model Publication No. 1-13844 has been developed. These have a flange portion having a larger diameter than the insertion hole at the lower end of the shaft portion that is inserted into the insertion hole of the sheet material, and have a pantograph-like engaging band that can be bent and stretched at the upper end. is there. During temporary attachment to the sheet material, the fastening belt is held in a flatly folded state, and the sheet material is sandwiched between the fastening belt and the flange portion in this state.

[0005]

However, according to the publications of both publications, when temporarily attaching the clip, it is necessary to perform work on both front and back surfaces of the sheet material. That is, the worker must insert the clip from the back side of the sheet material and fold the fastening belt on the front side. Generally, a dash silencer with a fairly large area is used, and the clips are attached at multiple points, and are not limited to corners, so work to temporarily attach the clip to a central part that is difficult to reach Then, the work is performed while searching for the hole position of the insertion hole, and the trouble cannot be endured.

It is an object of the present invention to provide a clip which eliminates such work from two directions when temporarily attaching the clip and realizes a quick and smooth work.

[0007]

[Means for Solving the Problems] As a means for achieving the above-mentioned object, the present invention fixes a sheet material having insertion holes penetrating in place and having cushioning properties to a body side through a fixing member. In the clip, a base formed to have a diameter larger than that of the insertion hole, a pillar that is erected substantially coaxially from the base and is formed so as to be freely inserted into the insertion hole, and connected to an upper portion of the pillar. At least a pair of pressing pieces for sandwiching the sheet material with the base is provided, and the column is loosely insertable into the insertion hole while the base elastically contracts one surface of the sheet material. In the natural state, the pressing piece takes a slightly larger overhanging posture than the insertion hole, and when it is inserted into the insertion hole, it closes so that it can pass through the insertion hole, but after passing through the insertion hole, from the edge of the insertion hole. After it overhangs, it is elastically deformable into an open-leg state in which it is subjected to the restoring elastic force of the sheet material and slides on the other side of the sheet material to overhang substantially horizontally. Is characterized in that it has a structure in which a recoil preventing portion is formed to prevent the elastic member from curving in the opposite direction after being in the opened state.

[0008]

Operation The operation of the present invention is as follows. When the pressing piece is inserted into the insertion hole of the sheet material from one side of the sheet material, one side of the sheet material is elastically contracted by the base, and the pressing piece is in a closed leg state and passes through the insertion hole. When the tip of the pressing piece passes through the insertion hole, the pressing piece returns to the natural state and projects to the outside of the rim of the insertion hole. Then, if the pushing force of the clip is removed, the pressing piece receives the restoring elastic force of the sheet material, and the pressing piece slides on the other surface of the sheet material to be in an open leg state in which the pressing piece projects substantially horizontally. As a result, the sheet material is sandwiched between the base and the pressing piece that has been opened, and the pressing piece is held in the predetermined open state without warping in the opposite direction by the recoil prevention portion, so that the necessary sheet material is maintained. The holding width is secured, and the clip is temporarily attached while firmly sandwiching the sheet material. Then, the entire sheet material is fixed to the body by the fixing means.

[0009]

As described above, according to the present invention, the clip can be temporarily attached to the sheet material only by inserting the clip into the insertion hole, and the inserting operation from one direction can improve the work efficiency. You can Also, after the pressing piece is in the predetermined open state, further curling is prevented, so that the clip is attached while firmly sandwiching the sheet material, and the pressing piece curls back into the insertion hole. It is reliably prevented that the sheet material floats up while returning. In addition to that, the restoring elastic force of the sheet material is used to extend the pressing piece to the open state,
Since the natural state of the pressing piece is limited to the overhanging posture that is slightly larger than the insertion hole, the shape of the pressing piece is compact, which is convenient when transporting a large number of groups at a time and also between pressing pieces. This has the effect of greatly reducing the possibility of collision and deformation or damage.

[0010]

Embodiments of the present invention will be described in detail below with reference to the drawings. An automobile dash silencer (hereinafter referred to as sheet material 1) to which the clip C of this example is attached.
2) of the urethane resin layer 1a and the vinyl chloride layer 1b.
A layered structure is used, and it has good cushioning properties so that it can be easily compressed and deformed. And the insertion hole 2 penetrates and is formed in the suitable place.

Now, the clip C of this example is integrally molded of a synthetic resin material, and as shown in FIG. 1, a disk-shaped base 3 having a diameter larger than that of the insertion hole 2 is formed at the lower end thereof. Has been done. A through hole 5 into which the stud bolt 4 planted on the body B side can be loosely inserted is opened at the center of the base 3.

A gate-shaped support 6 is erected on the upper surface of the base 3 with a through hole 5 interposed therebetween, and is formed to be sufficiently smaller than the diameter of the insertion hole 2 so that it can be loosely inserted into the insertion hole 2. ing. A window portion 7 having a predetermined width is formed through the support 6 in the radial direction so that the stud bolt 4 can be housed inside the support 6. Further, a pair of claw pieces 8 face each other in a direction in which the window portion 7 penetrates at the opening edge of the through hole 5, and both claw pieces 8 are elastically fixed to the stud bolt 4 as a fixing means for the body B side. Engageable. In addition, the wall surfaces on both sides of the support column 6 above the predetermined height position are both thinned to serve as relief portions 6a when both pressing pieces 9 to be described later are deformed in the closed legs. Further, a guide portion 10 for the insertion hole 2 is coaxially erected on the upper surface of the column 6. This guide part 1
Although the base side of 0 has a slightly smaller diameter, the head side has a larger diameter and the upper surface thereof is a pointed guide surface 10a.
Has become.

The guide portion 10 is provided with a pair of pressing pieces 9 in a direction orthogonal to the opening direction of the window portion 7. The two pressing pieces 9 are slightly lower than the peripheral edge of the most protruding portion of the guide portion 10, and the hinge pieces 11 are respectively formed.
Are connected to each other, and a bending deformation operation as described below is possible.

That is, as shown in FIG. 1 and the like, both pressing pieces 9 are set to be slightly open in their natural state, and the distance between the leg ends is set to be slightly larger than the diameter of the insertion hole 2 in advance. Then, when the clip C is pushed into the insertion hole 2, the clip C can pass through the insertion hole 2 by performing a bending deformation (closed leg deformation) so as to approach the escape portion 6a of the column 6. On the other hand, the lengths of both holding pieces 9 are set so that the distance between the tips is sufficiently larger than the diameter of the insertion hole 2 in the open leg state in which the holding pieces 9 are extended substantially horizontally. In this embodiment, the diameter is set larger than the diameter of the base 3. However, in order to prevent the opened legs of the pressing pieces 9 from being warped further upward from the horizontal position, the connecting portion with the hinge piece 11 engages the lower surface of the protruding portion 10b of the guide portion 10 at the horizontal position. ing. Further, when the tips of both holding pieces 9 pass through the insertion hole 2 due to the insertion of the clip C, the both holding pieces 9 can be returned from the closed leg state to the natural state, that is, the state having the overhang amount larger than the insertion hole 2. It has a certain amount of resilience.

Further, a pair of spring pieces 12 project obliquely downwardly below both pressing pieces 9 on both side surfaces of the support column 6, and each of them is flexibly deformable in a direction approaching the support column 6 side. Both spring pieces 12 are flexibly deformed by the two pressing pieces 9 when they are inserted into the insertion holes 2 so as not to prevent the both pressing pieces 9 from passing through the insertion holes 2, and after passing through the insertion holes 2. It plays a role of assisting the returning operation of both pressing pieces 9 to the natural state through the elastic returning operation of itself. However, the overhanging width (distance between the tips) of both spring pieces 12 in the natural state is set to be equal to or slightly larger than the hole diameter of the insertion hole 2, whereby both pressing pieces 9 pass through the insertion hole 2. At the same time, it also has a role of preventing the tip of the pressing piece 9 from being caught in the hole edge of the insertion hole 2.

Next, the operation of attaching the sheet material 1 will be described. First, the work of temporarily attaching the clip C to the sheet material 1 is performed. That is, when the guide portion 10 of the clip C is fitted into each of the insertion holes 2 of the sheet material 1 and pushed in as it is, both pressing pieces 9 are bent and deformed in the closed leg direction while pressing the corresponding spring pieces 12 to the relief portions 6a of the support columns 6. Then, the whole is inserted into the insertion hole 2. And FIG.
While pressing the sheet material 1 from the side of the base plate 3 as shown in FIG. At this time, both spring pieces 12 elastically return to assist the return operation of the corresponding pressing pieces, so that both pressing pieces 9 open to the natural state above the insertion hole 2 and the space between both pressing pieces 9 is increased. As for the amount of leg opening, at least the overhanging width of the spring piece 12 is secured, so that the tip of the pressing piece 9 does not get caught on the edge of the insertion hole 2.

After that, when the pushing on the clip C is released, the sheet material 1 returns by its own elasticity, so that the clip C is pushed back downward. Along with this,
As shown in FIG. 5, both pressing pieces 9 are automatically opened until they reach a substantially horizontal state. However, since the base portions thereof engage with the projecting portion 10b of the guide portion 10, the legs do not open further. Thus, the clip C is temporarily attached to the sheet material 1 while being clamped by the base plate 3 and the two pressing pieces 9.

As described above, the clip C is the sheet material 1
If it is attached to, the work of attaching to the body B is performed. That is, when the stud bolt 4 of the body B is fitted into the through hole 5 of the clip C and the sheet material 1 is strongly pushed to the body B side, the stud bolt 4 engages with both the claw pieces 8. Thus, the sheet material 1 is the body B
Pasted on.

As described above, the temporary attachment of the clip C to the sheet material 1 can be performed simply by inserting it, that is, the operation can be performed on the sheet material 1 from one direction, so that the work can be performed smoothly and quickly. it can. Further, since the clip C can be attached only from one direction, it is easy to mechanically perform this operation, and further improvement in working efficiency can be expected by doing so. Furthermore, since the clip C can be made into a single component, it can be handled more easily than before.

The present invention can be modified in various ways. For example, a plurality of pairs of the pressing pieces 9 can be set, and the elastic force of the pressing pieces 9 is strengthened to insert the insertion hole 2 It is possible to omit the spring piece 12 as long as the spring piece 12 is set so as to be surely returned to the natural state when passing through.
Further, as the fixing means to the body B, in addition to the claw piece 8 as in the present example, it is conceivable to form a retaining portion elastically engaged with a hole penetrating to the body B side. Furthermore, in this example, the T-type stud bolt 4 is used for fixing to the body side, but a method of engaging with a screw type stud may be used.
