Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid mounting device, and more particularly to a lid mounting device used for a vehicle lamp or the like.

[0002]

2. Description of the Related Art Conventionally, in a lid mounting device of this type, as shown in FIG. 9, for example, an engaging protrusion 21 provided on a synthetic resin lid 2 on a flange 11 at an opening edge of a vehicle body 1. Is locked. Further, a support portion 22 is provided on the lid body 2, a hole portion 23 is provided in the support portion 22, and a metal clip 3 is attached to the lid body 2 to elastically attach to the flange 11 of the vehicle body 1 via the clip 3. It is installed on.

Further, the clip 3 has a flat plate-like base portion 31 made of a single metal plate, and an elastic locking piece 33 is formed at an end edge of the base portion 31 via a bent portion 32.

[0004]

However, in such a conventional lid mounting device using the clip 3,
In particular, since the clip 3 is formed with one elastic locking piece 33, the design is repeated in consideration of various points in order to increase the holding force of the elastic locking piece 33. In particular, if an attempt is made to give a holding force, the load force becomes high, the lid body 3 may be deformed, and the lid body 3 may fall off from the vehicle body 1. Further, if the workability is easy to assemble, the attachment force becomes weak and the lid body 3 Had a problem such as falling off the car body 1.

An object of the present invention is to easily fit a lid on a flange of an opening edge of a vehicle body,
An object of the present invention is to provide a lid attachment device that is hard to come off and that can be reliably attached to a vehicle body or the like after assembly without rattling due to vibration.

[0006]

SUMMARY OF THE INVENTION In order to solve the above conventional problems, the present invention is a lid attaching device in which a lid provided with a clip is detachably attached to an opening edge flange of a vehicle body or the like. Then, the clip is a base of one metal plate,
The edge of this base is folded back toward the base to provide a bent portion,
An elastic piece having a plurality of locking step portions is formed in the bent portion through a slit, and the plurality of elastic pieces are formed with different bending angles so that the bending amount can be varied. To do.

[0007]

The clip in the lid mounting apparatus of the present invention configured as described above is formed with the elastic piece having a plurality of locking step portions through the slits. Since the bending angle is formed differently so that the amount of bending can be varied, it can be fitted easily when it is attached to the flange of the opening edge of the vehicle body or the like, and it is difficult to pull it out after assembly.
Moreover, the lid body can be securely attached to the vehicle body or the like without being loosened due to vibration or the like.

[0008]

EXAMPLE An example of a lid mounting device according to the present invention will be described. FIG. 1 is a cross-sectional view showing a state in which a lid is attached to a vehicle body. 2 shows a perspective view of the clip, and FIG. 3 is a perspective view of the clip from the back side. FIG. 4 is a rear view of the clip, FIG. 5 is a cross-sectional view of an essential part showing the action of the clip, and FIGS. 6, 7 and 8 are explanatory views showing a state in which the clip is attached to the flange of the vehicle body.

A vehicle body 1 is formed with a flange 11 at the opening edge of the vehicle body 1, and a lid body 2 made of synthetic resin, such as a lens cover, is attached to the flange 11. More specifically, an engaging projection 21 is provided on one end of the lid body 2, and a support portion 22 is provided on the other end of the lid body 2, and a clip described later is inserted into the support portion 22. A hole 23 to be locked is attached.

The clip 3 is provided with a base portion 31 of a single flat plate-like metal plate and a bent portion 32 by folding an end edge of the base portion 31 toward the base portion. The bent portion 32 has two slits 36. , 37, three elastic pieces 33, 34, 35 are formed in this example. Further, the elastic pieces 33, 34, 35 are provided with locking step portions 330, 340, 350, respectively, by folding the upper part further inward. Reference numeral 38 is an engaging claw provided by cutting out the base portion 31.

That is, the clip 3 has three locking step portions 330, 340 and 35 with respect to the base portion 31 as shown in the drawing.
The elastic pieces 33, 34, 35 having the number 0 are formed. More specifically, as is clear from FIG. 5, the three elastic pieces 33, 34, 35 are on the left and right sides of the base 31. The elastic pieces 33 and 35 are formed at a bending angle θ1, the central elastic piece 34 is formed at a bending angle θ2, and the central elastic piece 34 is formed on the left and right elastic pieces 3 respectively.
The bending angle is made larger than 3, 35. That is, the bending angles of the elastic pieces 33, 35 on the left and right sides and the elastic piece 34 on the center are made different, so that the elastic pieces 33, 35 on the left and right sides and the elastic piece 34 on the center are configured to change the amount of bending. It is what

Therefore, the hole portion 23 in which the base portion 31 of the clip 3 configured as described above is provided in the support portion 22 of the lid body 2.
The engaging claw 38 provided on the base 31 is inserted into the hole 23.
Is engaged with the inner wall of the. And the lid body 2 provided with the clip 3
When attaching the to the flange 11 at the opening edge of the vehicle body 1,
First, the engaging protrusion 21 provided at one end of the lid body 2 is attached to the flange 1.
When the clip 3 provided at the other end is pressed against the opening edge of the vehicle body 1 as shown in FIG. 6, the elastic piece 34 at the center is first contacted and further pressed, as shown in FIG. The central elastic piece 34 bends inward. When pressed further,
As shown in FIG.
3, 35 further bends inward and engages with the plurality of locking step portions 330, 340, 350 on the end surface of the flange 11 at the opening edge, so that the lid 2 is securely attached to the flange 11 at the opening edge of the vehicle body 1. It is locked and attached to.

In the above-described embodiment, as shown in FIG. 8, the central elastic piece 34 is bent by the bending amount Y, and the left and right elastic pieces 33, 35 are bent by the bending amount X, respectively. Although the bending angle is formed differently so that the amount can be varied, the invention is not limited to the above-described embodiment, and the three elastic pieces 33, 34, 35 at the left and right sides and the center are formed with different bending angles. The elastic piece is 3
The depths of the slits 36 and 37 may be further changed without being limited to the individual pieces. That is, the clip 3 of the present invention has a plurality of elastic pieces 33,
Since the desorption force can be finely adjusted by 34 and 35, it is easy to fit when the lid 2 is assembled, and after the assembly, the elastic margin 33 at the center has a large lap margin, which makes it difficult to come off and vibrates strongly when the vehicle is traveling. Even if there is a shock, it does not fall off, and it is excellent in safety.

[0014]

As is apparent from the above-described embodiments, according to the present invention, the clip provided on the lid body has different bending angles so that the elastic pieces provided with a plurality of locking step portions have different bending amounts. Since it is formed, it can be easily fitted to the flange of the opening edge of the vehicle body, etc., and it can be difficult to remove after assembly, so the lid body can be securely attached to the vehicle body etc., and the lid body does not rattle due to vibration etc. It is possible to provide a highly safe product that does not fall off.
