Description

[Detailed description of the invention] Industrial field of application This invention relates to a mounting structure for a mark plate that fixes a mark plate to a panel such as the outer panel of an automobile body. When attaching a plate for marks (ornaments, etc.), first fit each resin retainer onto each boss of the plate for the mark, and then insert each boss with the resin retainer into each mounting hole drilled in the panel. This is a mark plate mounting structure in which the mark plate is fixedly attached to the panel so that it cannot fall off.

Conventional technology Generally, when this type of marking plate mounting structure is adopted, a waterproof structure is required to prevent water from entering the vehicle body through the mounting hole of the panel to which the marking plate is attached during car washes or in the rain. There is a need to. Therefore, as an example of a conventionally considered waterproof structure, as shown in FIG. After fitting the sponge washer 22 into the brim 21b of the mark 21,
Connect each boss 20a to each mounting hole 24 of the panel 24.
a, and deform the sponge washer 22 between each of the resin retainers 21 and the panel 24 to make them come into close contact with each other.
I am trying to make the space between the two waterproof.

Problems to be Solved by the Invention However, with the structure described above, there was a problem in that the work of attaching the sponge washers 22 to each resin retainer 21 one by one was extremely complicated.

Therefore, the purpose of the present invention is to solve the above-mentioned problems, and it is not necessary to attach the sponge washer to the resin retainer, and the space between the resin retainer and the panel can be reliably waterproofed. This provides a mounting structure for marking plates.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has two contact parts on the brim part of a resin retainer consisting of a main body part and a brim part, which press against the surrounding part of the mounting hole of the panel. In addition, the two contact portions are configured to be in close contact with the area around the mounting hole of the panel to provide a waterproof effect. That is, the resin retainer is provided with a first contact portion on the outer circumferential edge of the upper surface of the flange portion of the resin retainer, which is in close contact with the area around the mounting hole on one surface of the panel in a generally annular shape, and has a surface that is larger than the first contact portion. A second adhering portion is provided on one side of the panel at a predetermined interval on the main body side and is in close contact with the mounting hole in a substantially annular shape, and each of the bosses having the resin retainer externally fitted thereon is provided. When fitted into the mounting hole of the panel, the first contact portion and the second contact portion of the collar portion of the resin retainer form approximately annular shapes, that is, closed loops, around the mounting hole on one side of the panel. It was constructed in the form of an eggplant strip so that the surfaces were in close contact with each other. The above-mentioned annular shape does not necessarily refer to a circular band shape, but may be a band shape of any shape such as a polygonal shape.

Effects and Effects of the Invention According to the above structure, each resin retainer has two contact parts on the upper surface of the collar, so that each boss with each resin retainer fitted thereon can be inserted into each mounting hole of the panel. When fitted, the two contact parts of the flange of the resin retainer come into close contact with the peripheral part of the mounting hole of the panel in a substantially annular shape, so that a waterproof effect can be achieved. Therefore, the trouble of attaching the sponge washers to the resin retainer one by one can be saved. Moreover, since the two contact parts are brought into close contact with the panel in surface contact in an approximately annular shape, a double seal can be formed between the panel and the flange part, so that the waterproof effect can be further enhanced.

Examples This invention will be explained in detail below using examples shown in FIGS. 1 to 8.

In this embodiment, as shown in FIGS. 1 and 2, each resin retainer 1 is composed of a cap-like main body part 1a and a flange part 1b formed at the lower end opening of the cap-shaped main body part 1a. each boss 3a of the mark plate 3
After externally fitting each resin retainer 1, the boss 3a with the resin retainer 1 externally fitted is fitted into the mounting hole 2a of the panel 2 made of the outer panel of the vehicle body, and the flange portion 1b of each resin retainer 1 is fitted. The above two contact parts 1
f, 1g to the mounting hole 2a on one side of the panel 2 above.
The flange portion 1b and the panel 2 are pressed into close contact with the surrounding portion of the panel 2, so that a waterproof structure is formed between the flange portion 1b and the panel 2.

Each of the resin retainers 1 has a substantially conical cylindrical shape, with the lower end serving as an opening and the upper end serving as a closed part.
In other words, it consists of a roughly cap-shaped main body 1a and a flange 1b projecting outward over the entire outer periphery of the lower end opening of the main body 1a. This resin retainer 1 is preferably made of polypropylene or nylon, for example.

First locking portions 1c, 1c, 1d, 1d for panel locking are provided on the outer peripheral surface of the main body portion 1a at 90 degree intervals.
One of the opposing first locking parts 1c, 1c is formed in a substantially trapezoidal shape from the substantially central part of the outer circumferential surface toward the flange part 1b, as shown in FIG. On the other hand, the opposite first
As shown in FIG. 4, the locking parts 1d, 1d are undercuts that protrude and form a substantially trapezoidal shape from the approximate center of the outer circumferential surface to the side of the collar 1b, and are cut out in the lower half on the side of the collar 1b. form into a shape. moreover,
Locking parts 1d, 1d, 1c, 1c of the main body part 1a
A second locking portion 1e for boss fitting protrudes toward the axial center of the main body at 90-degree intervals on the inner circumferential surface of the portion above the axial center of the main body. ..., 1e are respectively bulged and formed. Also,
The flange portion 1b has a tip thereof curved upward and is provided with a first contact portion 1f forming an annular plane on the upper surface of its outermost periphery as shown in FIG. Collar part 1 on the main body side
A second contact portion 1g having an annular flat surface is provided at a portion b and spaced apart from the first contact portion 1f by a certain distance. When the resin retainer 1 is fitted into the mounting hole 2a of the panel 2, both of the contact portions 1f and 1g are formed into a substantially annular shape around the mounting hole 2a on one surface of the panel 2 with a constant pressure. The surfaces come into close contact and form a waterproof structure.

On the other hand, each of the bosses 3 protruding and formed on the back surface of the main body 3c of the plate 3 for markings, as shown in FIGS. An undercut portion 3b is formed that is cut around the circumference and extends a predetermined length along the axial direction, and a side surface of the undercut portion of the tip portion 3d is formed in a portion from the undercut portion 3b to the tip portion 3d. A curved concave portion 3e is formed by curving outward so that the angle formed by the bottom surface of the undercut portion 3b and the bottom surface of the undercut portion 3b is approximately 80 degrees.
The tip end portion 3d has its tip end outer peripheral edge all rounded so that it can be easily pushed into the resin retainer 1. Grooves 3f, 3f are formed facing each other in a portion from the undercut portion 3b of the boss 3a to the mark plate main body 3c to prevent sink marks during molding of the mark plate 3.

Next, plate 3 of marks related to the above configuration
This section explains how to install the . First, each resin retainer 1 is pushed in from the upper end of each boss 3a of the mark plate 3. At this time, since the diameter of the tip 3d of the boss 3a is larger than the diameter formed by the inner surface of each second locking portion 1e on the inner surface of each resin retainer 1, the tip 3d of the boss 3a is When it hits the portion 1e, the main body portion 1a is pushed outward by the tip portion 3d. Then, each of the bosses 3a passes through each of the locking portions 1e, and each of the second locking portions 1e is fitted into the small diameter undercut portion 3b of the boss 3a, and the main body portion 1a returns to its original shape. The inwardly curved portion above the locking portion 1e of 1a is pressed against the outer peripheral surface of the boss tip 3d, and the main body 1
a is deformed as a whole, and the curved recess 3e of the undercut portion 3b of the boss tip portion 3d is locked by each of the locking portions 1e, and the main body portion 1a and hence the resin retainer 1 are fitted and fixed to the boss 3a. , the boss 3a and the retainer 1 are irremovably assembled.

As described above, each resin retainer 1 fitted and fixed to each boss 3a is inserted into each mounting hole 2a from the outer surface side of the panel 2. When the main body part 1a of each resin retainer 1 is inserted into the mounting hole 2a, the main body part 1
Each of the first locking portions 1c and 1d of a is inserted while deforming inwardly and bending together with the main body portion 1a. When the thickness of the panel 2 is thin, the outer surface of the trapezoidal first locking portions 1c, 1c of one set is in the mounting hole 2a.
The mark plate 3 is firmly fixed to the panel 2 by pressing the panel 2 against the inner circumferential surface of the plate 3 . On the other hand, when fixing to a thick panel 2 or when burrs occur, the undercut first locking portions 1d and 1d of the other pair are attached to the area around the mounting hole 2a on the outer surface of the panel 2. The panel 2 is sandwiched between the two contact parts 1f and 1g of the collar part 1b in contact with each other, and the two contact parts 1 of the collar part 1b are
While the first locking portions 1d and 1d are pressed against the inner surface of the panel 2, the plate 3 for markings is It is firmly fixed to panel 2. When the above assembly is performed, the first and second contact parts 1f and 1g of the flange part 1b of the resin retainer 1 are brought into close contact with the entire periphery of the mounting hole 2a on the outer surface of the panel 2 in an approximately annular shape with a constant pressure. The contact portions 1f and 1g of the flange portion 1b prevent water from car washing or wind and rain from entering the interior of the vehicle body through the mounting hole 2a of the panel 2.

According to the above embodiment, the flange portion 1b of the cap-shaped resin retainer 1 is provided with two contact portions 1f and 1g, and each resin retainer 1 is provided in each mounting hole 2a of the panel 2.
When each boss 3a externally fitted is inserted and fitted,
The two contact parts 1f of the brim part 1b are attached to the panel 2,
1g is brought into close contact with the surface of the plate 3 in an approximately annular shape under a constant pressure, and the only communication path that communicates between the inside and outside of the panel 2 is double closed by the contact portions 1f and 1g. The mounting structure can be made waterproof. Therefore, there is no need to attach the sponge washer to the resin retainer 1.
There is no need to perform the work of attaching sponge washers to each resin retainer 1 one by one, and the work of attaching the plates 3 for markings becomes easy. In addition, the above-mentioned two contact parts 1f and 1g come into close contact with the panel 2 in a roughly annular shape, thereby creating a double seal between the panel 2 and the flange part 1b, thereby further enhancing the waterproof effect. be able to. In addition, since an undercut portion 3b is provided around the entire circumference of each boss 3a of the mark plate 3, positioning between the resin retainer 1 and the boss 3a is not required when assembling the resin retainer 1. Since it is only necessary to push it into the boss 3a, the assembly work is extremely simple.
Furthermore, each pair of the four first locking portions 1c, 1c, 1d, and 1d protruding from the outer periphery of the resin retainer 1 are formed into a trapezoid shape and an undercut shape in which the lower half of the trapezoid is cut out. , regardless of the thickness of the panel 2 or burrs in the mounting hole 2a, the first locking portions 1c, 1c of one set press against the inner peripheral surface of the mounting hole 2a of the panel 2. Since the first locking parts 1d and 1d of the other pair sandwich the panel 2 between the two contact parts 1f and 1g of the collar part 1b and press the area around the mounting hole 2a, the resin retainer is inserted from the mounting hole 2a of the panel 2. A large pulling force is required when pulling out the resin retainer 1, and the resin retainer 1 can be reliably attached to the panel 2. Also, boss 3
