Abstract

PROBLEM TO BE SOLVED: To provide a hole plug which can prevent a foamed material from being pressed out from an accommodation part of a plug even though a high pressure is exerted to the plug. SOLUTION: A foamed material 14 is formed into such a shape that a protrusion 14A bulges out from its circular outer periphery as seen in a plan view, and this protrusion 14A can be pulled out through a take-out port 22 formed in a plug 11 when the foamed material 14 is accommodated in an accommodation part 12, and is supported between a panel 30 and a skirt part 28 formed on the plug 11 when the plug 11 is fitted in the hole 26 in the panel 30. Accordingly, even though a strong wind pressure is exerted, or even though the foamed material 14 is pressed through a ventilation hole 18, the foamed material 14 is not projected from the accommodation part 12 of the plug 11 through an insertion opening 24 for the foamed material in the accommodation part 12, thereby it is possible to prevent entrance of water through the ventilation hole 18.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hole plug mounted in a hole formed in a panel.

[0002]

2. Description of the Related Art As shown in FIGS. 4 to 6, a hole plug 54 mounted in a hole 52 formed in a door panel 50 of an automobile or the like is provided with a plug 56 formed of a synthetic resin and a plug 56. Form 6 stored in the stored storage section 58
0.

[0003] A ventilation hole 62 is formed at the bottom of the storage portion 58 and is closed by a foam 60 having air permeability and waterproofness. Then, the air flows to the ventilation holes 62 through the foam 60. Also, plug 56
A hook 56A is provided on the outer periphery of the hole 52, and the hook 56A
The plug 56 is mounted on the second.

Further, a thin skirt portion 68 protrudes from the plug 56 in the radial direction, and the plug 56 is inserted into the hole 52.
When press-fitted, the skirt portion 68 comes into close contact with the door panel 50 to exhibit watertightness.

[0005] A pressing piece 56B projects toward the center of the insertion opening 61 of the foam 60 of the storage section 58.
The form 60 does not protrude from the insertion opening 61.

However, when the door 72 is strongly closed, the wind pressure on the door panel 50 from the direction A suddenly increases,
The form 60 jumps out of the insertion opening 61 of the storage section 58,
In some cases, water may enter the inside of the door panel 50 through the ventilation holes 62.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and has as its object to provide a hole plug in which a foam does not protrude from a housing portion of a plug even under a strong pressure.

[0008]

According to the first aspect of the present invention, a plug having a vent is provided. In addition, a storage portion is formed in the plug, and a foam for closing the ventilation hole is stored in the storage portion.

When the plug is mounted in the hole, the foam is sandwiched between the panel and the plug.

[0010] For this reason, even if a strong wind pressure is applied or the foam is pushed from the inside, the foam does not jump out of the storage portion of the plug, so that water can be prevented from entering through the vent hole.

According to the second aspect of the present invention, an outlet is formed on the peripheral wall of the storage portion, and a protrusion formed on the foam extends outward from the outlet.

[0012] For this reason, the projecting portion protruding from the outlet serves as a hanging margin, and the foam does not fall out of the storage portion during the mounting operation or during transportation of the hole plug. Further, even when the protruding portion is sandwiched between the plug and the panel and receives a strong wind pressure, the foam does not jump out of the storage portion. Furthermore, since the foam is in a state of being pulled outward when the protruding portion is sandwiched, the foam is not turned up.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A hole plug according to the present embodiment will be described.

As shown in FIGS. 1 and 2, the hole plug 10 has a cylindrical plug 11, and this plug 1
The inside of 1 is the storage section 12 in which the form 14 is stored. The foam 14 is formed of a polyether-based material. If the foam 14 is too thin, it is easily rolled up when subjected to pressure, and if it is too thick, the pressure loss becomes large when air is passed. (In this example, 3mm
degree).

On the other hand, a rib 16 is formed in the bottom of the storage portion 12 in a cross shape, and a portion without the rib 16 serves as a vent hole 18 so that air flows. The ventilation hole 18 is located inside the outer edge of the foam 14, and a gap is formed between the foam 14 and the ventilation hole 18 to prevent water from entering. The rib 16 serves as a pedestal when the foam 14 is stored in the storage unit 12 and supports the foam 14 so that the foam 14 is not bent by external water pressure.

A hook 20 is projected from the peripheral wall 11A of the plug 11, and the hook 11 is hooked on the edge of the hole 26 so that the plug 11 is mounted in the hole 26. You.

Further, a thin skirt portion 28 extends radially from the peripheral wall 11A of the plug 11 over the entire circumference.
It is slightly inclined toward the hook 20. For this reason, when the plug 11 is pressed into the hole 26, the skirt portion 28 is elastically deformed and adheres to the panel 30 to exhibit watertightness.

On the other hand, the form 14 has a shape in which a projection 14A protrudes outward from a circular outer periphery in a plan view.
The projecting portion 14A can be pulled out from the outlet 22 formed in the plug 11 when the foam 14 is stored in the storage portion 12. Also, outlet 2
A pressing piece 22A is formed on 2 to prevent the protrusion 14A from falling off when the protrusion 14A is pulled out from the outlet 22.

Further, when the plug 11 is mounted in the hole 26 of the panel 30, the protrusion 14A is sandwiched between the panel 30 and the skirt 28 formed on the plug 11.
For this reason, even if it receives a strong wind pressure or presses the foam 14 from the ventilation hole 18, the foam 14 does not jump out of the insertion portion 24 of the foam 14 of the storage portion 12 from the storage portion 12 of the plug 11. 18 can be prevented from entering.

The length of both ends of the protrusion 14A is slightly shorter than the outer diameter of the skirt 28 of the plug 11.
Therefore, when the plug 11 is mounted on the panel 30, the foam 14 does not protrude from the plug 11, so that watertightness can be ensured.

Further, the protrusion 1 protruding from the outlet 22
4A serves as a hanging margin, and the foam 14 does not fall out of the storage section 12 during the mounting operation or during transportation of the hole plug 10. In addition, since the foam 14 is pulled from both sides by sandwiching the protrusion 14A, the foam 14 is not turned up.

In the present embodiment, the outlet 2 of the plug 11
2 is provided in two places, but three or four places may be provided,
The protrusion 14A of the foam 14 may be formed correspondingly.

In this embodiment, the form 1 is stored in the storage section 12.
3, the peripheral wall 11A of the plug 11 may be partially cut out to form an arc-shaped rib 44 that can be inserted into the hole 26 (see FIG. 2).
On the other hand, the form 36 has a circular shape in a plan view, and has an arc-shaped notch 36 </ b> A having a size through which the rib 44 can be inserted.
To form Then, the notch 36A of the foam 36 is inserted into the rib 44, and the rib 44 is inserted into the hole 26 so that the foam 36 is sandwiched between the panel 30 (see FIG. 2) and the skirt portion 42 formed in the plug 11. Is also good. Thereby, since the insertion of the form 36 can be easily performed, the number of work steps can be reduced.

[0024]

According to the present invention, since the foam does not jump out of the storage portion of the plug even if it receives a strong wind pressure or presses the foam from the inside, the intrusion of water can be prevented. .

Further, the foam does not fall out of the storage portion during the mounting operation or during the transportation of the hole plug. Further, the foam does not turn over.
