Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the installation of a blind lid for closing an opening such as a working hole formed in an interior / exterior panel of an automobile or an inner / outer plate of a vehicle body. Regarding the structure.

[Prior art]

Conventionally, as this type of blind lid, what is called a grommet as shown in FIGS. 10 and 11 is known.

The grommet 2 is made of rubber or soft synthetic resin, has a disc shape as a whole, and has a structure in which a groove 3 which can be fitted into a working hole 5 of a panel 4 is provided. Then, when the grommet 2 is fitted into the work hole 5, the peripheral edge of the groove 3 comes into close contact with the work hole 5 by the elastic recovery force of rubber or soft synthetic resin, and the work hole 5 is surely closed.

[Problems to be solved by the invention]

However, since the grommet 2 which is a conventional blind lid has a complicated sectional shape, the manufacturing cost is high. Further, if the entire circumference of the groove 3 is not properly fitted into the working hole 5, there is a problem that it is dislocated due to vibration or the like. Especially in cold weather, the elastic recovery force decreases, and it is difficult to attach and detach the work hole 5.

The present invention has been made in view of the above-mentioned problems of the prior art,
It is an object of the present invention to provide a blind lid mounting structure which has a simple structure, is inexpensive, can be easily attached and detached, and is hard to be separated by vibration.

[Means for Solving the Problems]

In order to achieve the above object, in the structure for mounting a blind lid of a panel working hole according to the present invention, a thin plate made of synthetic resin is provided with a central region of a size matching the working hole of the panel and an outer periphery of the central region. The tongue piece radially extends from four equally divided portions to form a cross shape.

[Action]

When the blind lid is attached to the panel working hole with one pair of two tongue portion regions facing each other across the central region on the back side of the panel and the other pair on the front side, the deformed tongue piece is deformed. A restoring force that tries to return to the original shape acts between the partial areas,
Therefore, the tongue portion area clamps the peripheral edge of the work hole from both front and back sides, and the blind lid is attached to the work hole.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

Fig. 2 is a perspective view of a splash guard with a blind lid attached, Fig. 3 is an enlarged perspective view of a work hole peripheral portion with a blind lid attached, and Fig. 4 illustrates a state in which the blind lid is attached. FIG.

In these drawings, reference numeral 8 is a polypropylene splash guard, which is attached and fixed to the side frame so as to cover the right front wheel of the automobile, and protects the engine room from muddy water and pebbles splashing up from the front wheel. An opening 9 for adjusting the timing of the engine is formed at a substantially central portion of the splash guard 8.

Reference numeral 10 is a blind lid made of polypropylene thin plates in a cross shape. The blind lid 10 has a square-shaped central region 12 having a size matching the hole 9 to be mounted, and a tongue region 14 radially extending from each side position of the central region 12.
(14a to 14d).

Each of the tongue piece regions 14 (14a to 14d) has a chevron shape, and a notch 13 having a plate thickness of the blind lid is provided at the base portion thereof, so that each tongue piece region 14 is located at the root position ( (Shown by reference numeral 15) makes it easy to bend and fits the opening 9 to the peripheral edge portion in a good condition.

Next, a procedure for mounting the blind lid 10 on the opening 9 will be described.

First, as shown in FIG. 4, a pair of tongue piece regions 14a and 14c facing each other with the central region 12 sandwiched between them are pinched and bent by the index finger and thumb. Then, the folded tongue piece regions 14a and 14c of the blind lid are inserted into the opening 9 from the surface of the splash guard (on the back side of the plane of FIG. 2). Then, the pair of tongue piece regions 14a and 14c inserted into the fourth
As shown by the phantom line, it spreads out on the back side of the splash guard. Then, the four tongue portion regions 14 are staggered by the openings 9 alternately,
The peripheral portion of the opening 9 is clamped by the restoring force generated between the tongue region regions 14a and 14c on the front side of the splash guard and the tongue piece regions 14b and 14d on the back side.

FIG. 3 shows the blind lid 10 attached to the opening 9, and the tongue portion region 14 has a restoring force as shown by arrows in FIGS. 3 and 4. To remove the blind lid 10,
The pair of tongue piece regions 14b and 14d are pulled to deform the blind lid and pull out from the opening 9.

Thus, in the present embodiment, the pair of tongue piece regions 14a, 1
4c is simply inserted so as to be inserted into the opening 9, and the blind lid is easily attached. Once attached, the pair of tongue portions clamp the peripheral portion of the hole, so that external force such as vibration is applied. Then it doesn't come off easily.

Furthermore, since the notch 13 formed in the base of each tongue piece region 14 makes it easy to bend the tongue piece region, the blind lid 1
It is possible to smoothly attach and detach 0. Further, the blind lid 10 is bent at the position of the notch 13 that engages with the peripheral edge of the opening 9, and the blind lid 10 has good adhesion to the opening 9.

FIG. 5 shows another embodiment of the blind lid according to the present invention.

In the blind lid 10A of this embodiment, the tip portions 16 (16a to 16d) of the adjacent tongue piece regions are curved in the same direction. Then, when the blind lid 10A is attached to the opening 9, as shown in FIG. 6, the tongue piece region tip portions 16a and 16c are in pressure contact with the splash guard surface, and the base portion of the tongue piece region 14 is formed. The peripheral edge portion of the opening 9 is clamped at both the tip portion 16 and the tip portion 16. Therefore, as compared with the first embodiment, the blind cover fits better in the opening 9. Further, the tongue-shaped region tip portions 16b and 16d are in a state of floating on the side opposite to the insertion direction of the blind lid, and the blind lid can be easily removed by pulling the raised portion. Others are the same as those in the first embodiment, and the description thereof will be omitted by giving the same reference numerals.

FIG. 7 shows a third embodiment of the blind lid according to the present invention.

In the blind lid 10B of this embodiment, the pair of tongue piece regions 24b and 24d of the two pairs of tongue piece regions 24 are the central region 12.
Although it is formed in the same plane as the tongue piece, a step 25 slightly lower than the plate thickness of the splash guard 8 is formed at the base position of the other pair of tongue piece regions 24a, 24c. The piece regions 24a and 24c extend horizontally. Since the step 25 is formed,
As shown in FIG. 8, a blind lid 1 for the rectangular opening 9A is provided.
The degree of fitting of 0B and the adhesion to the peripheral portion of the opening are improved. Further, as shown by reference numeral 26, the tips of the tongue piece regions 24a and 24c are bent back to the side opposite to the mounting surface, and when the blind lid 10B is removed, this bent back portion 2
It is easy to remove by pulling and removing 6.
The other points are the same as those in the above-described embodiment, and the description thereof will be omitted by giving the same reference numerals.

It should be noted that by appropriately forming a mark in the central region 12, it can be used as a position display means of the panel work hole.

FIG. 9 shows still another embodiment of the present invention, which has a structure in which a thin portion 13a is formed at the notch 13 position of the blind lid 10 shown in FIG. This blind lid 10C has an opening 9
Since the thin portion 13a adheres tightly to the peripheral edge of the opening 9 during attachment to, it is effective in reliably closing the opening 9 without a gap.

In addition, for example, when stamping the splash guard, burrs are generated around the molded splash guard, but if this blind lid is simultaneously molded with the splash guard in this burr area, burrs will be effective. Available.

Further, the case where the blind lid is attached to the openings 9 and 9A of the resin splash guard has been described as an example. However, for example, the drain hole of the metal inner plate disposed on the bottom surface of the vehicle interior is closed. It may be a blind lid.
