Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a plate attachment device used when attaching a plate to a member to be attached with bolts.

(Prior art) For example, when attaching a license plate to a bumper with bolts, the bumper, which is the part to be attached, is mounted closely to the vehicle body panel and it is difficult to reach the back side of the bumper. A locking nut etc. must be installed in advance.

Japanese Utility Model Application Publication No. 58-136847 proposes a nut mounting device for use in such cases, and FIG. 4 shows the main parts of the device. The mounting device shown in the figure includes an L-shaped overhang 3 provided on both sides of a through-hole 2 for bolt insertion on the back side of a bumper 1, and a nut plate 4 that is inserted through the overhang 3 and held. , and a nut 5 attached to the nut plate 4 by welding or the like, and has a structure in which the shaft portion of the bolt is inserted through the through hole of the license plate into the through hole 2 of the bumper 1 and tightened to the nut 5 to lock it. ing. This mounting device is applied to cases where the nut 5 cannot be easily mounted on the object to be mounted, such as a synthetic resin bumper, and the nut 5 can be easily mounted before mounting the bumper 1 on the vehicle body. This will be convenient when installing the license plate at a later date.

(Problems to be Solved by the Invention) However, in the conventional mounting device, the L-shaped overhang 3 must be formed on the bumper 1, which is the member to be mounted, so the molding die becomes complicated, and Even if the overhanging part 3 is formed integrally with the bumper 1, it is difficult to obtain accurate spacing between the bumper 1 and the overhanging part 3, so there is a risk that the nut plate may come off during transportation before being fixed with bolts. Moreover, in such a device, since the nut is small, it is difficult to attach the nut 5 to the nut plate 4, and since the axes of the nut must be aligned with the bolt, it is troublesome to fix the nut.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a plate mounting device that can be easily temporarily fixed to a member to be mounted and that can improve the mounting strength.

(Means for Solving the Problems) In order to achieve the above object, the present invention involves inserting a bolt into a through hole in a plate and locking the shaft portion of the bolt in a clip provided on a member to which it is attached. A mounting device for fixing the plate by,
The clip includes a guide hole through which the shaft of the bolt is inserted, a receiving portion that intersects with the guide hole and immovably holds a nut that is screwed into the bolt, and a receiving portion that is provided on the attached member. It is characterized by comprising a leg part which is temporarily fixed by being elastically inserted into the through hole, and which is expanded and crimped when a bolt is inserted into the guide hole.

(Function) According to the above configuration, the clip is temporarily fixed by holding the nut immovably in the receiving portion and then inserting the leg portion into the through hole of the member to be attached. Further, by tightening the bolt while threading it into the nut, the clip is crimped onto the member to which it is attached, and the plate is firmly fixed to the member to which it is attached by the bolt and nut.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the main parts of the mounting device according to the present invention,
FIG. 2 shows the plate installed using the same device. In these figures, a plate 10 such as a license plate is attached to a clip 30 temporarily fixed to a member 20 to be attached such as a vehicle bumper.
It is attached by inserting and tightening a bolt 40.

The clip 30 is made of a resin molded body, and includes a guide hole 31 through which the shaft portion 41 of the bolt 40 is inserted, a receiving portion 32 that intersects the guide hole 31, and a receiving portion 32.
When the leg portion 33 is loosely fitted into the recess 21 provided in the mounted member 20 as shown in FIG.
It is temporarily fixed by inserting 3.

The guide hole 31 passes through the leg part 33 from the top, but the hole diameter on the leg part 33 side is set to be slightly smaller than the bolt shaft diameter, so that when the shaft part 41 of the bolt 40 is inserted and pushed, the leg part 33 is being expanded. The receiving part 32 has a space slightly smaller than the square nut 50, and the guide hole 31
Located on the upper side of the guide hole and intersecting with the guide hole,
Its front and rear sides are open. Each opposing surface of the front opening 32a is tapered to widen toward the opening edge, making it easy to insert the square nut 50. Conversely, the rear opening 32b is narrower than the receiving part 32, and the nut 5 inserted into the receiving part 32b is narrower than the receiving part 32.
0 is not omitted. Also, the receiving part 3
Recesses 34 are provided on both sides of 2 in the front-rear direction with a wall in between. This recess 34 allows the receiving portion 32 to
The wall between the front opening 32a and the recess 34 is easily elastically displaced, and the nut 5 is inserted into the receiving portion 32 from the front opening 32a.
When the nut 50 is inserted, the nut 50 is resiliently held immovable.

Further, the leg portion 33 has a substantially inverted conical shape.
3a, and a neck portion 33b located above the engaging portion 33a.
By providing vertical slits 33c in the engaging portion 33a and the neck portion 33b, the diameter can be reduced or expanded by the elasticity of the resin. In other words, leg 3
3 is elastically inserted into the through hole 22 while contracting in diameter, and upon completion of insertion, expands in diameter and returns to its original state, thereby being temporarily fixed to the member to be attached 20. In addition, the leg portion 33 has a bolt 40 inserted into the guide hole 31.
The diameter of the clip 30 is also expanded when the clip 30 is inserted into the mounting member 20, and this expansion causes the clip 30 to be firmly crimped onto the member to be attached 20.

When such a clip 30 is used, the nut 50 can be easily held immovably in the clip. Further, after temporarily fixing the clip 30 to the member to be attached 20 as described above, align the through hole 11 of the plate 10 with the opening of the guide hole 31, insert the bolt 40 into the through hole 11, and then attach the clip 30 to the member 20.
By screwing and tightening the nut 50 held by the clip 30, the clip 30 is brought into pressure contact with the member 30 to be attached, and the plate 10 is fixed to the member 30 to be attached. Of course, this fixation is done using metal bolts 4.
0 and nuts 500, sufficient fixing strength can be obtained. Furthermore, even when attaching a license plate to a bumper, for example, there is no need to attach nuts to the bumper before installing the bumper on the vehicle body, as is the case with conventional methods, and work can be done only on the surface side of the bumper. This makes it extremely convenient since it is only necessary to temporarily fasten the clip 30 when installing the plate.

(Effects of the Invention) As explained above, according to the plate attachment device of the present invention, the clip can be easily and reliably temporarily fastened without making any changes to the attachment target member, and the plate can be temporarily attached to the attachment target member. Can be firmly fixed with bolts and nuts. Moreover, compared to the conventional example, the operation of attaching the nut becomes easier, and the clip does not come off even if the member to be attached is transported while the clip is temporarily attached. Of course, temporary fixing of the clip can be performed even after the members to be attached are assembled.
