Description

Description: TECHNICAL FIELD The present invention relates to a mounting structure of a blocking plug for mounting in a hole formed in a floor of an automobile, and particularly to mounting the blocking plug in a predetermined direction. Thus, the present invention relates to a mounting structure that effectively prevents damage to the panel surface due to external pressure during traveling, and also effectively protects damage to the block plug.

[Prior Art] Japanese Patent Publication No. 59-22107 discloses a plug for fitting and closing a hole formed in a floor of an automobile. That is, a panel portion having a substantially continuous perimeter and a plurality of members each hanging from the panel portion from a position radially spaced from the perimeter of the panel portion and snapped into an opening in the panel. Forming a plug consisting of individual legs,
A ring of heat-flowable sealing material is provided on the outer peripheral surface of the panel portion to form a continuous band of sealing material between the perimeter of the panel portion and the legs, and the stopper is placed on the opening of the panel to seal the sealing material. The present invention relates to a structure for sealing an opening of a panel, which includes steps of heating the surface of the panel to a temperature sufficient to cause it to flow over the irregularities, thereby effectively sealing the opening.

[Problems to be Solved by the Invention] However, in such a conventional technique, as shown in FIG. 5, the entire surface of the closure plug 1 for sealing in the hole is flat. Since the leg body 3 which is engaged with the peripheral edge of the hole 4 is extended from the flange 2 having the planar shape and is inserted into the hole 4, it is not specified particularly when the vehicle runs on a bad road. Gravel stones and the like collide with the floor surface 5, and at this time, the stones that collide with the block plug 1 collide with the force greater than the adhesive force of the resin body to damage the block plug 1 or separate and weld it. The same holes 4 as before will be formed again or the floor surface 5 will be deformed.

Moreover, since the conventional obstruction plug 1 is formed so as to be obstructed as a surface that is substantially the same as the floor surface 5, it is susceptible to external resistance and unconditionally liable to be damaged by external pressure such as gravel stone Pb. .

[Means for Solving Problems] The present invention was developed in order to effectively solve the above-mentioned conventional problems, and the portion of the peripheral surface of the panel drilling hole on the floor of the automobile is provided. A covering flange, an embossing body that is held by the flange and hangs down, and projects from the lower surface of the panel drilling hole, and a pair of attachments that extend a predetermined width from the flange and hang down below the outer surface along the embossing body. An obstruction plug having a leg portion is attached by embedding a soluble resin body between the peripheral surface of the panel drilling hole and a flange, and the pair of attachment leg portions of the obstruction plug are arranged in a direction orthogonal to the traveling direction of the vehicle. It is an object of the present invention to provide an attachment structure of a blocking plug which is arranged and in which the embossed body is arranged to face the traveling direction of the automobile.

[Operation] Therefore, in the present invention, by adopting the present closure plug, the presence of the embossed body enables more stable attachment to the panel drilling hole than the conventional one, and at the same time, the attachment leg portion is Since they are mounted in a predetermined direction, the automobile floor surface can effectively prevent damage from gravel stones due to external pressure due to the presence of the mounting legs and the embossing body.

That is, since most of the gravel stones fly in the same direction as the traveling direction of the automobile, many gravel stones fly in the same direction as the traveling direction, which causes the plug plug. It is easy to hit because of the presence of the embossed body protruding below the floor surface, and therefore has a protective effect on the entire floor surface.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings of FIGS. 1 and 2.

The closure plug 10 used in this embodiment is composed of two parts, one part of which is press-molded with a metal material as shown in FIG. 1, and the other part is as shown in FIG. In addition, the resin body 14 having a soluble property to be fitted around the outer periphery of the component serves as a cap body having a large welding force.

That is, a flange 11 that covers the peripheral surface portion of the panel drilling hole on the floor of the vehicle, an embossing body 13 that is held by the flange 11 and hangs down, and projects from the lower surface of the panel drilling hole, and the flange 11 Extend more, embossed body 13
A closure plug (10) having a mounting leg portion (12) hanging downward along the outer surface thereof is provided.

That is, the closing plug 10 is a plug having a circular outer surface that is molded so as to fit exactly into a circular coating heating moving attachment hole that is formed in the floor surface 17 of the vehicle 18. 17 There is a flange 11 that abuts on the surface and is in close contact, and there is an embossed body 13 that is smaller than the outer diameter of the flange 11 and that hangs from the lower surface and has a bottom surface as a cylindrical body.
A pair of mounting legs 12 are formed that extend from the outer diameter of 11 by a predetermined width and that extend in the same direction with respect to the outer surface of the embossing body 13 at a slight interval in a substantially symmetrical arrangement. .

The embossed body 13 has a certain depth, and the mounting leg portion 12 is also formed to have the same height or more according to the embossed body 13.

The mounting leg portion 12 has its tip bent inward for ease of insertion.

Further, the soluble resin body 14 as another component is the blocking plug.
A through hole (15a) is formed in the center so as to be outside the mounting leg (12) included in (10), and the blocking plug (10) is inserted into the through hole (15a) for use.

As a result, the block plug 10 has a floor surface made of a soluble resin material.
It will be abutted by 14.

Thus, after the blocking plug 10 described above is attached to the hole formed in the floor surface 17 of the vehicle 18, the vehicle body passes through the moving drying oven for surface drying.

The obstruction plug 10 is heated while the vehicle 18 is passing,
The soluble resin body 14 integrated with 10 is melted, welded to the vehicle 18, and solidified.

By this step, the blocking plug 10 blocks the hole, and it is possible to expect waterproof and dustproof effects.

At this time, the obstruction plug 10 has its mounting direction changed to the mounting leg portion.
It is important to arrange the 12 directions so as to be orthogonal to the traveling direction of the vehicle, that is, the left-right direction. (See FIG. 4) As a result, the embossed body 13 is disposed so as to face the traveling direction of the vehicle, and the impact gravel Pa is first applied to the embossed body 13 of the closure plug 10 by an impact in the traveling direction. You will hit.

Further, other gravel stones directly collide with the bottom surface 13a of the embossed body 13, but in any case, since it collides with the shape projecting downward from the vehicle floor surface 17, the floor surface is It is protected and does not cause serious damage to the obstruction plug 10 itself or the floor surface 17 itself.

Thus, the obstruction plug 10 is attached to the hole formed on the floor surface 17 of the vehicle 18 with the mounting leg portion 12 facing in the direction orthogonal to the vehicle traveling direction, so that the mounting leg portion 12 of the conventional example or more is mounted. Due to the size and the presence of the embossed body 13 projecting from the floor surface 17, the floor surface 17 can be effectively protected from the impact gravel stone Pa.

Therefore, the obstruction plug 10 can be prevented from being damaged, and safety in running the vehicle is ensured.

It should be noted that the pair of mounting legs 12 need only be provided with mutual mounting positions such that the pair of mounting legs 12 can be mounted in a direction orthogonal to the vehicle traveling direction as described above. It does not necessarily have to be symmetrically arranged.

[Effects of the Invention] As described above, the following effects can be obtained by adopting the attachment structure of the blocking plug according to the present invention.

(1) A large impact gravel stone is formed by arranging the pair of mounting legs in a direction orthogonal to the traveling direction of the vehicle and disposing the embossing bodies facing each other in the traveling direction of the vehicle.
You can hit the embossed body and protect the floor effectively.

(2) Since the block plug uses a soluble resin body that melts in a heating furnace for adhesion, it uses the vehicle painting process and does not need to use any other adhesion process, so it can be installed inexpensively. Not only is it possible, but it also has a strong fixing force, which gives it the same existence value as one complete floor surface.

(3) Since the mounting position is clarified by the mounting direction of the mounting legs, the work process can be performed efficiently, and the arrangement relationship of the embossing bodies is clarified, and the effect of protecting the floor surface is further obtained.
