JPS5854293Y2 - Waterproof structure for car cab floor penetrations - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a waterproof structure for a floor penetrating portion of an automobile cab.

Conventionally, when a car is driven through muddy or snowy areas, muddy water and the like easily splashes onto the steering column and part of the cover and enters the interior of the vehicle, resulting in contamination of the interior of the vehicle.

In addition, since snow and muddy water tend to accumulate on the outside of the floor 4a in FIG. 1, which shows a conventional example, the floor member 4 tends to rust, posing a risk of corrosion.

Furthermore, only a horizontal space is formed between the support part 2 of the steering column cover 1 and the floor member 4, and the structure is such that only the sealing material 3 is filled in, so the waterproof function is not achieved. It was insufficient.

The present invention was devised to eliminate the drawbacks of the prior art described above, and its purpose is to eliminate muddy water from the outside.
The object of the present invention is to completely prevent the infiltration of dust, snow, etc., and to eliminate corrosion of floor members inside the cab of an automobile, and to make this possible with an extremely simple structure.

In short, the present invention provides a waterproof structure for an indoor/outdoor penetration part of an indoor floor surface of an automobile cab, which includes: a joint part of a cover of a penetrating member; a bent floor member flange part parallel to the joint part; A supporting part consisting of a part that extends horizontally and hangs down from the body part, a space communicating with each other in the horizontal and vertical directions is formed between the parts, and the space is filled with a sealing material. It is something to do.

The present invention will be described below based on embodiments shown in the drawings and compared with conventional examples.

In FIGS. 1 to 3, the conventional steering column cover 1 supports the column cover 1 by a support portion 2 and a lower end portion 1b of a body portion 1a of the column cover 1, and is supported by appropriate bolts. Whereas the floor member 4 was attached to the floor member 4 through the sealing material 3, the present invention, as shown in FIG.
At the lower end of the body portion 1a of the column cover 1, there is provided a joint portion 1 that loosely fits into the flange 45, and a support portion 2 that supports the column cover 1 against the surface of the floor member 4.
This is provided.

The support part 2 consists of two parts, one is a support part 2c that is parallel to the floor member 40 surface and extends from the body part 1a of the column cover 1, and the other part is an end part of the support part 2c. This is a vertical supporting portion 2a that hangs down from the bottom to the floor and is in contact with the floor.

Note that the support portion 2a does not necessarily have to be perpendicular to the floor surface and may be inclined.

A space C is formed between each of the above parts 1c, 2c, 2a4 and 4b, which communicates in the horizontal and vertical directions, and the space is filled with a sealing material 3 such as a rubber material or a flexible synthetic resin, so that the space C communicates not only in the horizontal direction but also in the horizontal direction. It is also sealed in the vertical direction to improve its waterproof function.

Also, the outwardly extending portion 2. of the support portion 2c. In this case, the extension part 2d consists of horizontal and vertical parts, and not only serves as a reinforcement part for the column cover 1, but also forms a double waterproof structure by filling this part with a sealing material. .

Furthermore, if the length of the vertical portion is shortened as shown in the figure, it is possible to improve the appearance by laying a floor mat in the interior of the automobile, and it is possible to prevent the reverse intrusion of dirt into the interior of the vehicle.

Further, the mat itself can act in the same manner as the sealing member to serve both of these functions.

The sealing material 3 is filled in a space C formed by the joint 1°, the support portion 2, and the floor member 4.

Since the sealing material 3 is completely confined by the fitting between the joint portion 1c and the flange portion 4b, the sealing effect becomes even more effective.In addition, the sealing material 3 is also filled between the flange portion 4b and the joint portion 1c. Therefore, the sealing performance is sufficient.

In particular, the excess sealing material 3 is removed from the supporting part 2 and the horizontal floor member 40.
Even if you fill only the horizontal space formed by the
The sealing material 3 is compressed by tightening a bolt or the like and flows into the space between the joint portion 1c and the flange portion 41, which is favorable for sealing.

This waterproof structure can be applied not only to the steering column and part of the cover, but also to penetrations inside and outside the cab, such as the air intake ports of car heaters and car coolers.

The present invention is constructed as described above, and its operation will be explained below.The sealing material 3 is connected to the joint portion 1c, the horizontal surface of the floor member 4, and the flange portion 4. and the support part 2 and are held under pressure, especially the joint part 1c and the flange part 45.
Since it is securely tightened by fitting with the seal material 3
are in complete contact with each surface of the floor member 4, and the intrusion of muddy water and the like from the outside is reliably prevented.

Since the present invention is constructed and operates as described above, the sealing action is reliably guaranteed, and the effect of preventing muddy water, snow, dust, etc. from entering from the outside can be obtained.

In addition, since the areas where mud, snow, etc. tend to accumulate, such as the protruding outside of the floor 4 in the conventional example, can be removed, snow and dust will not be particularly resistant to adhesion, and even if they are scattered on these areas, Since it will fall immediately, the effect of preventing the progression of corrosion of floor members etc. can be obtained.
