Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor mat for an automobile that is installed in a vehicle interior to prevent the interior of the vehicle from getting dirty.

(Prior Art) An automobile floor mat that is used by being placed on the floor of an automobile may shift from its predetermined position due to frequent getting in and out of the automobile, lifting and lowering of the foot while driving, etc. . If such misalignment occurs, not only will the floor surface of the car become dirty, but especially if the car floor mat shifts forward, it will obstruct the operation of the brake pedal, etc., and in some cases, the car may become damaged. This will interfere with driving.

In order to prevent such misalignment of the automobile floor mat with respect to the vehicle body, a spindle-shaped protrusion is provided on the back surface of the automobile floor mat, as seen in, for example, Japanese Patent Laid-Open No. 58-143733. A device has been proposed that uses a protrusion to prevent misalignment. (See FIG. 10) However, simply providing a spindle-shaped protrusion on the back surface of an automobile floor mat is still insufficient in terms of preventing slippage. This is because the spindle-shaped protrusion alone is less likely to catch on the floor surface.

Furthermore, a mounting system as seen in Japanese Utility Model Application Publication No. 59-149539 has also been proposed. This mat has a large number of two-stage protrusions arranged on the back side of a mat made of thermoplastic resin, but it is virtually impossible to apply resistance over a wide area with each protrusion alone.

Furthermore, the floor surface of a car is rarely a perfect flat surface, and the surface of the carpet placed on this floor surface is naturally not a perfect flat surface, but a curved surface. This is often the case. For this reason, it has been difficult with the above-mentioned prior art techniques to make a floor mat for an automobile completely conform to this curved surface and to prevent the above-mentioned slippage.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned circumstances, and the problem to be solved is the misalignment of an automobile floor mat with respect to the floor surface.

An object of the present invention is to provide a floor mat for an automobile that has a simple structure and is more effective in preventing slippage.

(Means for Solving the Problems) The means taken by the present invention to solve the above problems will be explained with reference to FIGS. 1 to 8 corresponding to the embodiments. A large number of concave portions 20 projecting downward are formed on the back surface portion 11 of the automobile mat,
In a floor mat 10 for an automobile, in which each protrusion 20 prevents slipping against the vehicle body when placed on the floor surface of an automobile, each of the protrusions 20 is connected to a central protrusion 21, and the central protrusion 21 This floor mat 10 for an automobile is characterized by comprising a plurality of auxiliary protrusions 22 extending laterally from the central protrusion 21 and having a lower height than the central protrusion 21, and in which the respective protrusions 20 are spaced apart from each other.

(Actions of the Invention) By adopting the above-described measures, the present invention has the following effects. That is, when the automobile floor mat 10 is placed on the floor surface of an automobile as shown in FIG. Touch the floor first. Generally, the floor of an automobile is covered with a carpet, so the tip of the central protrusion 21 sinks into the carpet. Thereafter, the outer edge (lower edge in FIG. 3) of each auxiliary protrusion 22 contacts the abutting carpet and sinks slightly into it.

At this time, since the convex portions 20 are formed apart from each other, especially when the carpet laid on the floor of the automobile is made of a long-pile material, there is no carpet between the convex portions 20. This ensures that each convex portion 20 sinks into the carpet. In other words, if the protrusions 20 are continuous, or if there is any protrusion that bridges the protrusions 20, the top surface of the carpet will come into contact with the continuum or protrusion, causing the car floor mat 10 to come into contact with the carpet. Since the applied force is also dispersed to these parts, it is not guaranteed that each convex part 20 will sink into the carpet.
In the present invention, by spacing the protrusions 20 from each other, the force applied to the automobile floor mat 10 is reliably applied to each protrusion 20, and only in order to cause the protrusion 20 to completely sink into the carpet. It is now possible to use it.

Furthermore, at this time, since the convex portions 20 are spaced apart from each other, the automobile floor mat 10 is easily bent in the portion located between the convex portions 20. Therefore, this automobile floor mat 10 can reliably conform to the curved surface of the automobile floor, and each convex portion 20 can be reliably depressed into the carpet.

In this way, when the automobile floor mat 10 is placed on the floor of an automobile, the central protrusion 21 constituting the convex portion 20 collapses into the carpet laid on the floor, and the convex Since the edge of each auxiliary protrusion 22 constituting the portion 20 is slightly recessed into the carpet, the automobile floor mat 10 is secured by each central protrusion 21 and the plurality of auxiliary protrusions 22 constituting the convex portion 20. This means that it will be firmly held against the floor of the car. As above,
The automobile floor mat 10 does not shift from its predetermined position even when the user frequently gets in and out of the car, lifts and lowers the foot while driving, etc.

(Example) Next, an automotive floor mat 10 according to the present invention will be described according to an example shown in the drawings. FIG. 1 shows the back side of an automobile floor mat 10 according to the present invention, and this automobile floor mat 10 has a backing portion 11 made of rubber or the like formed on the back side of a base fabric (not shown) into which pile threads have been driven. be. A large number of protrusions 2 are provided on the back surface 11 of this automobile floor mat 10.
0 is formed integrally with the back surface portion 11.

As shown in FIGS. 2 and 3, each convex portion 20 includes a central protrusion 21 that protrudes perpendicularly from the back surface portion 11.
The central protrusion 2 extends laterally from the central protrusion 21.
The center projection 21 and the auxiliary projections 22 are made of the same material as the back surface 11 when forming the back surface 11 described above. It is integrally formed with. Of course, each of the auxiliary protrusions 22 is also formed to protrude perpendicularly from the back surface portion 11. The central protrusion 21 and auxiliary protrusion 22 constituting the convex part 20 are made to protrude perpendicularly from the back surface part 11 because these central protrusion 21 and auxiliary protrusion 2
This is to make it easier to remove from the mold when forming the back part 2 and the back part 11 at the same time.

Further, as shown in FIGS. 1 to 8, the respective convex portions 20 are spaced apart from each other by a predetermined distance (in the embodiment shown in the drawings, approximately 2 to 3 times the size of each convex portion 20).
They are spaced apart. That is, there is nothing between the convex parts 20 except for the back surface part 11.

In the example of FIG. 1, a case has been described in which the convex portions 20 are formed in mutually parallel rows and columns so that the respective auxiliary protrusions 22 are located at the same position. As shown, each auxiliary protrusion 22
They may be arranged alternately with the two rotated by 45 degrees. Further, as shown in FIG. 7, each auxiliary protrusion 22 is arranged so that the convex parts 20 are arranged horizontally, vertically, and the convex parts 20 are arranged so that each auxiliary protrusion 22 is rotated by 45 degrees. You may.

In addition, in FIG. 2, each auxiliary protrusion 22 is
Although an example in which one is formed has been described, three may be formed as shown in FIG. 4. Furthermore, in FIG. 2, only the tip of each auxiliary protrusion 22 is formed in a slightly curved state, but as shown in FIG. It may also be carried out. The convex portions 20 shown in FIG. 5 may be arranged in equally spaced rows and columns as shown in FIG. 1, or they may be arranged in opposite directions as shown in FIG. The convex portions 20 may be arranged alternately.

By considering the arrangement of the respective convex portions 20 as shown in FIGS. 6 to 8, the frictional resistance of each convex portion 20 against the floor surface of the automobile can be improved, especially for the automobile floor mat 1.
This can increase the frictional resistance when the 0 tries to rotate.

In addition, although the drawing describes an automobile floor mat in which the back side is lined with base fabric, the automobile floor mat is not limited to this, and the entire mat may be made of rubber, or a part of the rubber mat may be used. The base fabric may be embedded in the base fabric.

(Effects of the Invention) As described in detail above, according to the automobile floor mat 10 according to the present invention, as illustrated in the above embodiment, each of the central protrusion 21 and the auxiliary protrusion 22 constituting each convex portion 20 is Since the mat 10 reliably sinks into the floor surface of the automobile, the friction of the automobile floor mat 10 against the floor surface increases and it is possible to prevent the automobile floor mat 10 from shifting from the floor surface. Moreover, even if each convex part 20 can be easily constructed integrally with the back surface part 11 and each convex part 20 is composed of a central protrusion 21 and an auxiliary protrusion 22, the cost of the automobile floor mat 10 itself can be reduced. Nor can it be increased. Furthermore, in this automobile floor mat 10, the convex portions 20 are spaced apart from each other, so that the automobile floor mat 10 can be bent freely in the portion where the convex portions 20 are not present. In addition to reliably following the shape of the floor surface, each convex portion 20 is reliably depressed into the carpet on the floor surface, and displacement can be reliably prevented.
