Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a carpet for a vehicle, and particularly to a carpet for a vehicle formed with a rubber backing.

(Prior Art) A carpet is usually laid in the cabin of a vehicle.
This vehicle carpet prevents the floor of the vehicle or the carpet laid on it from becoming dirty,
It allows dirt, dust, etc. to be easily removed from the vehicle interior, and is also used to make the interior of the vehicle more luxurious.

This type of vehicle carpet is one on which feet are directly placed, and the foot may be displaced from its predetermined position due to the force exerted thereon. Various proposals have been made to prevent this positional shift. For example, protrusions may be provided on the rubber backing, or a portion of a vehicle carpet may be fixed to the vehicle body. However, in order to fix a part of a vehicle carpet to the vehicle body, such a fixing device must be prepared, and it is virtually difficult to provide something that is suitable for all types of vehicles. . Furthermore, when forming protrusions on the backing rubber, if the location and number of protrusions are not carefully considered, the protrusions will cause the vehicle carpet to rise above the floor surface, rendering it practically useless. Moreover, with this method of providing the protrusions, it is extremely difficult to resist forces from all directions on the vehicle carpet.

Furthermore, the floor in the vehicle interior often has a curved surface, especially in the surrounding area, and the vehicle carpet must fit onto the floor in the vehicle interior, which has this curved surface. Otherwise, even if a protrusion as described above is provided to prevent displacement, it will be suspended from the floor and will be useless.

(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 by the invention is the misalignment of carpets for vehicles of this type with respect to the floor surface.
The purpose of this invention is to create a vehicle that can be securely fixed to the floor of the vehicle and resist forces applied from all directions by applying simple processing to the rubber lining. Our goal is to provide carpets for

(Means for Solving the Problems) In order to solve the above problems, the means taken by the present invention will be explained with reference to FIGS. 1 to 4 corresponding to the embodiments. 1. Rubber 12 A large number of columnar protrusions 21 are arranged at predetermined intervals on the back surface of the rubber 12, and a large number of columnar protrusions 21 having a height lower than each columnar protrusion 21 are arranged between the columnar protrusions 21. Vehicle carpet 1 formed with elongated protrusions 22
0, each elongated protrusion 22 is arranged radially with respect to each columnar protrusion 21, and each of these columnar protrusions 2
1 and each of the elongated protrusions 22, and each of the elongated protrusions 22 has an acute angle portion 22c on its front, rear and top surfaces. .

(Aspects of operation and use of the invention) Such a vehicle carpet 10 is used by simply placing it on the floor surface of the vehicle interior. Of course, in this case, the vehicle carpet 10 is placed with the carpet 11 facing upward, and the vehicle carpet 10
The backing rubber 12 is in contact with the floor surface.

At this time, on the back side of the lining rubber 12,
Since the elongated projections 22 are arranged radially with respect to each of the columnar projections 21 and a predetermined gap is formed between each of the columnar projections 21 and the elongated projections 22, the vehicle carpet 10 Even if the long protrusions 22 are present, the parts other than these can be bent freely. Therefore, even if there is a pole surface on the floor on which the vehicle carpet 10 is laid, the vehicle carpet 10 will bend in accordance with the curved surface of that portion, so it will not completely follow the floor surface. , each columnar projection 21
etc. will not rise from the floor.

In this manner, when the vehicle carpet 10 is simply placed on the floor surface of the vehicle interior, the tops of the respective columnar protrusions 21 provided on the backing rubber 12 come into contact with the floor surface, and the backing rubber 12 is supported floating at a certain height. Therefore, since the vehicle carpet 10 itself is supported by each columnar projection 21, the gravity of the vehicle carpet 10 is distributed to each columnar projection 21. As a result, each columnar projection 21 comes into firm contact with the floor surface inside the vehicle interior. At this time, if the floor surface is covered with a so-called carpet-like material, the columnar projections 21 will fit into the carpet, so that each columnar projection 21 can be fixed even more reliably.
In particular, each columnar protrusion 21 is arranged to form a predetermined interval between each of the following elongated protrusions 22. Since a portion of the carpet is inserted into the carpet, each columnar projection 21 can be reliably inserted into the carpet.

If a foot is placed on the vehicle carpet 10 in such a state, an additional force is applied to the vehicle carpet 10, so that each columnar protrusion 2
1 will bend (if the floor is made of hard material) or sink into the floor (if the floor is carpet-like). When this happens, each of the elongated protrusions 22 comes into contact with or sinks into the floor surface at one top 22a. As a result, the vehicle carpet 10 has each columnar projection 21 and each elongated projection 22.
It is also supported on the floor by one top portion 22a of the top portion 22a. That is, by a large number of parts,
The vehicle carpet 10 is supported on the floor surface inside the vehicle interior.

In this case, the direction of the force applied to the vehicle carpet 10 is often not constant, but even so, a large number of columnar projections 21 and elongated projections 22 are provided, and especially in the case of the elongated projections 22, Since the columnar projections 21 are formed in multiple directions in different directions, the vehicle carpet 10 is reliably fixed to the floor surface without being affected by the direction of the force applied to the vehicle carpet 10.

In short, the vehicle carpet 10 is reliably supported against forces in its downward and lateral directions by the actions of the columnar projections 21 and the elongated projections 22. On the other hand, since the columnar projections 21 and the elongated projections 22 cannot provide any resistance against upward force, when attempting to remove the carpet 10 for the vehicle, It is sufficient to simply lift the carpet 10 upwards, and the carpet 10 can be easily kept out of the way when cleaning the interior of the vehicle.

(Example) Next, the specific structure of the vehicle carpet 10 according to the present invention will be explained with reference to the drawings.

FIG. 1 shows a vehicle carpet 10 according to the present invention.
This vehicle carpet 10 is formed by lining the back surface of a carpet 11 with a backing rubber 12. FIG. 2 shows the back side of the vehicle carpet 10 according to the present invention, and the backing rubber 12 shown here has a large number of backing rubbers 12 and elongated protrusions 22 formed thereon.

Each columnar protrusion 21 is formed integrally with the backing rubber 12 in a state of being dispersed at predetermined intervals on the back surface of the backing rubber 12, and in this embodiment, is formed in a cylindrical shape. Further, each columnar projection 21 is arranged on the back surface of the rubber lining 12 at the intersections of the lattice and at the center of these intersections. However, the arrangement of each columnar projection 21 is not limited to this embodiment, and can be changed as appropriate. In addition,
Each columnar projection 21 shown in FIGS. 2 and 3 has a flat top surface, but as shown in FIG. 21a may be formed. By forming the small protrusions 21a on each columnar protrusion 21, fixation to the floor of the vehicle is effective, especially when the floor is carpet-like.

Each elongated protrusion 22 is disposed between the above-mentioned columnar protrusions 21 and is formed integrally with the backing rubber 12, and as shown in FIGS. 2 and 3, each of the columnar protrusions 21, and a predetermined gap is formed between each of these columnar projections 21. In this embodiment, there are two types of elongated protrusions 22, long ones and short ones, in terms of the length of their long sides.

As shown in FIG. 3 and FIG.
The height of the top portion 22a is made lower than that of the columnar projection 21. This is because if no force other than its own weight is applied to the vehicle carpet 10 itself, it is better to support the vehicle carpet 10 only by each columnar projection 21. Also,
The reason why one apex 22a of each elongated projection 22 is formed higher than the other apex 22b is to make it easier for the higher one apex 22a to first contact or bite into the floor or carpet. Furthermore, one apex 22a and the other apex 22b of each of these elongated protrusions 22 face toward the columnar protrusion 21 in the vicinity thereof. This is so that when the rubber backing 12 bends or sinks into the floor surface, the elongated protrusion 22 can immediately support the vehicle carpet 10 as an aid to the rubber backing 12 that bends or sinks into the floor surface. This is to make it happen.

Further, in this embodiment, an acute angle portion 22c is continuously formed on the upper surface of each elongated protrusion 22 in the longitudinal direction, as shown in FIG. As a result, especially the top surface portions of each of the one top portion 22a and the other top portion 22b have an acute angle shape. This is done in order to ensure that the elongated protrusion 22 contacts or sinks into the floor surface.

(Effect of the invention) As explained above, according to the vehicle carpet 10 according to the invention, on the back surface of the backing rubber 12,
A large number of columnar projections 21 are arranged at predetermined intervals, and one top portion 2 is arranged between these columnar projections 21.
A large number of elongated protrusions 22 are formed such that a predetermined gap exists between them, and each elongated protrusion 22 is radial with respect to each columnar protrusion 21. It is characterized by the fact that it is arranged and formed as shown in FIG. Even if a force is applied to the vehicle carpet 10, it will not easily shift from the floor surface of the vehicle interior. In particular, with this invention,
Since a large number of elongated protrusions 22 are arranged between each columnar protrusion 21, even if the support provided by the rubber lining 12 loses its effectiveness, each elongated protrusion 22 exerts a supporting action instead. Therefore, the support of the vehicle carpet 10 to the floor surface is ensured.

Moreover, each elongated protrusion 22 is arranged such that one apex 22a and the other apex 22b face each backing rubber 12, so that each columnar protrusion 21
Since the supporting action of each elongated protrusion 22 occurs at the same time as the carpet flexes or sinks into the floor surface, even if a foot is placed on the vehicle carpet 10 and forces are applied in all directions, the vehicle carpet 10 will not touch the floor surface. Support of the carpet 10 is immediately ensured.

Furthermore, since the shape of each columnar projection 21 and elongated projection 22 is simple, it is extremely easy to integrally form such elongated projection 22 and columnar projection 21 on the backing rubber 12. It is possible.
