Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for attaching a synthetic resin mounting member such as an undercover for a vehicle to a mating member such as a vehicle body panel or a synthetic resin panel.

[0002]

2. Description of the Related Art In order to mount such a synthetic resin mounting member on a mating member, mounting holes formed in corresponding portions of these two members are overlapped, and a clip is inserted therethrough. By the way, in a member made of a synthetic resin, in particular, a member formed by vacuum forming, a change (variation) in the plate thickness is large. This is not an exception in the case of a mounting member such as an undercover for an automobile or a panel made of a synthetic resin. For this reason, the clip has a structure capable of absorbing a change in plate thickness.

A conventional clip is an integrally molded product made of a synthetic resin. The clip is inserted into a mounting hole of a mating member and a mating member, so that a locking leg that locks to an outer peripheral portion of the mounting hole of the mating member and a fixing member are attached to the clip. And a holding section for holding the front side. The holding portion is provided with a dish-shaped stabilizer that comes into contact with the surface of the mounting member with elastic force, and absorbs the change in the plate thickness by the amount of deflection of the stabilizer.

[0004]

However, when inserting the locking leg of the clip into the mounting hole, it is necessary to apply a load for bending the dish-shaped stabilizer. Are getting bigger and the workability is getting worse. An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to be able to absorb a change (variation) in a plate thickness of a member made of a synthetic resin, and to further suppress the insertion load of a clip into a mounting hole. It is to be.

[0005]

According to the present invention, there is provided a clip for attaching a mounting member made of synthetic resin to a mating member. In addition, individual mounting holes formed at corresponding locations of the mating member can be inserted into these mounting holes in a state of being overlapped, and can be engaged with the outer peripheral portion of the hole while passing through the mounting hole of the mating member. It has a locking leg for stopping, and a holding portion that remains on the surface side of the mounting member and holds the mounting member. The holding portion is set to have a shape that spreads around a portion connected to the locking leg, and elastic pieces protruding toward the locking leg are formed at a plurality of locations.

According to this structure, when the locking leg is inserted into the mounting hole, each elastic piece comes into contact with the surface of the mounting member and is elastically deformed, thereby mounting the same as a conventional dish-shaped stabilizer. Changes (variations) in the plate thickness of the member or the mating member can be absorbed. In addition, since these elastic pieces are individually formed at a plurality of locations on the holding portion, the load required to bend them is small, and the load for inserting the locking leg into the mounting hole is small, so that workability is improved. Will be better.

According to a second aspect of the present invention, there is provided the clip according to the first aspect, wherein the side of the holding portion facing the surface of the mounting member is a substantially flat holding surface, and the elastic piece is formed on the outer periphery of the holding portion. The portion is formed at a predetermined angle with the holding surface. In this case, in addition to the function of the first aspect, the holding state of the mounting member by the holding portion is stabilized.

Embodiments of the present invention will be described below. FIG. 1 is a perspective view showing a synthetic resin clip, and FIG.
Is a plan view thereof. 3 is a front view of FIG. 2, and FIG. 4 is a side view of FIG. The clip 10 shown in these drawings is an integrally molded product made of a synthetic resin, and roughly includes a locking leg 12 and a holding portion 20. On the other hand, the mounting member 3 made of a synthetic resin indicated by a virtual line in FIGS.
Mounting holes 31 and 33 are formed at locations corresponding to 0 (for example, a vehicle undercover) and its mating member 32 (for example, a vehicle body panel). 3 and 4 show a state where the mounting holes 31 and 33 are overlapped with each other.

The locking leg 12 includes a column 14 extending from the holding section 20 and a pair of locking pieces 16 extending toward the holding section 20 from both sides of the tip of the column 14. These locking pieces 16 can be elastically deformed in a direction in which the spread to both sides changes, and thereby can be inserted into the mounting holes 31 and 33 where the locking legs 12 are overlapped. The locking surface 18 formed at the tip of both locking pieces 16 is provided so that the locking leg 12
When the mounting hole 33 passes through the mounting hole 33,
To the outer periphery of Reinforcing portions 24 are formed at two places where the support 14 and the holding portion 20 are joined, mainly for the purpose of reinforcing the wobble of the support 14.

[0010] The holding portion 20 is provided with a support post 14 (locking leg 1).
2) is set to have a substantially circular shape that spreads around the center with respect to the coupling portion with 2), and the side facing the surface of the mounting member 30 when the clip 10 is used is a substantially flat holding surface 22. Rectangular elastic pieces 26 projecting toward the locking legs 12 are formed at two locations facing each other at an interval of 180 ° on the outer peripheral portion of the holding portion 20. These elastic pieces 26 are formed by cutting the holding surface 22 side of the holding portion 20 with a predetermined thickness, and separating each of the holding portions 20 while leaving one side thereof, and individually having a predetermined angle with respect to the holding surface 22. It has a cantilever shape.

Using the clip 10 described above, the mounting member 30
In order to attach the two members 30,
32, the mounting holes 31 and 33 are overlapped with each other as shown in FIGS.
Insert 2. As a result, the locking pieces 16 are elastically deformed so as to narrow the spread to both sides, and are inserted into the mounting holes 31 and 33. When both ends of the locking pieces 16 pass through the mounting holes 33, they return to their original state, and the respective locking surfaces 18 are locked to the outer peripheral portion of the mounting holes 33 on the back surface of the mating member 32.

On the other hand, the two elastic pieces 26 are attached to the mounting holes 3.
With the insertion of the locking legs 12 (both locking pieces 16) into the mounting holes 30, the surface of the mounting member 30 is brought into contact with the locking surface 18 of the locking pieces 16 as described above. In the final stage of locking, the elastic deformation occurs as shown by the imaginary line in FIG. The amount of elastic deformation of the elastic pieces 26 absorbs a change (variation) in the plate thickness of the mounting member 30, which is a synthetic resin part, and functions as a stabilizer. Further, since the elastic pieces 26 are individually formed at two places of the holding portion 20, unlike the conventional dish-shaped stabilizer, it is necessary to bend these elastic pieces 26 as shown by phantom lines in FIG. The load can be reduced, and the insertion load of the locking leg 12 into the mounting holes 31 and 33 is reduced.

As described above, the locking leg 12 is attached to the mounting holes 31, 33.
The reinforcing portion 24 is located at least in the mounting hole 31 of the mounting member 30 in the state of being inserted into the mounting member 30. The holding portion 20 remains on the surface side of the mounting member 30 together with the two elastic pieces 26, and the holding surface 22 thereof faces the surface of the mounting member 30. In addition, the holding portion 20 has a substantially circular shape centered on the joint portion with the locking leg 12, and the width of the holding surface 22 is sufficiently ensured. For these reasons, even when the clip 10 receives some external force in its use state, the clip 10 does not rattle against the mounting holes 31 and 33 and the holding state of the mounting member 30 by the holding section 20 is stable. .

The elastic pieces 26 can be formed at three or more places on the holding portion 20, but the insertion load of the locking legs 12 does not increase in relation to the number and the individual elastic force. It is necessary to take care. Further, the mating member 32 may be an iron plate such as a body panel or a synthetic resin panel similar to the mounting member 30. When the mating member 32 is a panel made of synthetic resin, the thickness of the panel may vary, and this is absorbed by the amount of elastic deformation of the elastic piece 26.
