DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stepping mat.

[0002]

2. Description of the Related Art Conventionally, as a treading mat which is turned on when a person steps on it, for example, as shown in FIG. 7, an upper surface and a lower surface in a hollow portion b of an elastically deformable tubular protective film a are provided. It has been known that a linear treading switch e in which a plus wire c and a minus wire d are fixed so as to face each other with a space therebetween is disposed in a mat. When a person steps on the treading mat (treading switch e), as shown in FIG.
The protection film a is flattened by the treading pressure f, and the plus line c comes into contact with the minus line d to be in an energized state (ON state).

[0003]

However, in the conventional treading mat as described above, even if the treading area is extremely small, the treading switch e is always turned on when a part of the treading switch e is depressed. There was a problem that even when a person other than a human stepped on, it responded.

Therefore, the present invention solves the above-mentioned problem,
An object of the present invention is to provide a tread pressure mat that can be reliably turned ON when a person steps on the vehicle and can be prevented from being turned ON when something other than a person steps on the vehicle.

[0005]

In order to achieve the above-mentioned object, a stepping mat according to the present invention comprises a pair of pressurizing members connected in series at predetermined intervals by conductors. A stepping pressure switch unit that is turned ON only when the members are simultaneously stepped down is constituted, and the stepping pressure switch unit is connected in parallel between the first wiring and the second wiring on the plus / minus side so as to be connected in parallel. Many are arranged above.

The predetermined distance between the pair of pressurizing members of the stepping pressure switch unit is such that the pair of pressurizing members can be depressed at the toe portion and the heel portion of the shoe sole of the standard size. Is set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIG. 5 shows an embodiment of a treading mat according to the present invention. This treading mat A is laid in a state where one or a plurality of treading mats are connected to a floor surface or the like, and a human foot (shoe sole). It is turned ON only when the user steps on the vehicle, and detects passage of a person. The rectangular mat body 1 and the mat body 1
And waterproof connectors 30, 30 formed on two sides parallel to each other so as to protrude outward and outward. In the illustrated example, two treading mats A, A are connected to each other by a connecting chain 31. This shows a state in which the two waterproof mats A, A are connected to each other so as to form an interval B, and the pair of opposed waterproof connectors 30, 30 of the two treading mats A, A are electrically connected to each other.

As shown in the simplified plan view of FIG. 1, the tread mat A includes a first wiring 4 on the plus side and a first wiring 4 on the minus side, which are arranged on the same plane and are separated from each other. 2
And a wiring 5. Further, the first wiring 4 and the second wiring 5
A large number of treading switch units U are arranged on a plane so as to be connected in parallel.

The first wirings 4 and the second wirings 5 are each made of a bare conductor, and are arranged in parallel with a predetermined mutual interval. The plurality of first wirings 4 are electrically connected to each other and connected to the waterproof connector 30. Similarly, the second wirings 5 are also electrically connected to each other and to the waterproof connector 30.

As shown in an enlarged view in FIG. 2, the stepping pressure switch unit U includes, as a pair of members (pressurizing members) G that can be energized when pressurized, for example, a pair of pressurizing conductive rubber pieces. 2 and 2 are connected in series at a predetermined interval S by a conductor 3 and are turned ON only when the pair of pressurized conductive rubber pieces 2 and 2 are simultaneously stepped on. Here, the pressurized conductive rubber piece 2 has a high electric resistance in a non-pressurized state, has almost no conductivity, and has an electric resistance only when an external pressure is applied by stepping on a human foot or the like. Refers to a rubber piece that exhibits reduced conductivity and exhibits conductivity.

The stepping pressure switch unit U will be described in more detail. A short bare wire as the conductor 3 is disposed between the first wiring 4 and the second wiring 5 at right angles, and both ends of the conductor 3 are connected to each other. The first wiring 4 and the second wiring 5 are slightly separated so as not to contact with each other. Then, one pressurizing current-carrying member G (pressurizing conductive rubber piece 2) is placed and abutted on one end of the conductor 3 and over the first wiring 4, and The pressure conducting member G (pressurized conductive rubber piece 2) is placed and abutted so as to straddle the other end of the conductor 3 and the second wiring 5. In other words, the first wiring 4, the second wiring 5, and the conductor 3 are arranged in a grid shape so as to be separated from each other, and the pressurizing member G (the pressurizing conductive rubber piece 2) is provided at the intersection of the grid. ) Are placed so as to straddle the ends of the conductors 3 and 3 and the ends of the first wiring 4 or the second wiring 5.

Thus, (back to FIG. 1) the predetermined interval S between the pair of pressurizing members G, G (pressurizing conductive rubber pieces 2, 2) of the treading switch unit U is equal to the standard size shoe sole C. A pair of pressurizing members G, G at the toe 6 and the heel 7
(Pressurized conductive rubber pieces 2, 2) so that each can be treaded,
Is set. The predetermined interval S is, for example, 60 mm
It is preferably about 140 mm. The reason is that if the predetermined interval S is less than 60 mm, a pair of pressurizing members G and G (pressurizing conductive rubber pieces 2 and 2) are simultaneously applied to the feet D (small feet) of animals such as dogs and cats. This is because the ON reaction by those animals cannot be excluded because the stepping force can be applied. Also, the predetermined interval S
Is greater than 140 mm, the pair of pressurizing members G, G (pressurizing conductive rubber pieces 2, 2) cannot be simultaneously pressed by a person's foot (soles), and the person must be on the stepping mat A. Is no longer detectable.

FIG. 1 shows a case where one pressurizing energizing member G (pressurizing conductive rubber piece 2) is also used for two stepping pressure switch units U and U. That is, in one arbitrary stepping pressure switch unit U, the two pressurizing energizing members G, G (pressing conductive rubber pieces 2, 2) as constituent elements thereof are:
They are in contact with the conductors 3 and 3 of the other adjacent contact switch units U and U, respectively. Thereby, the stepping pressure switch units U can be densely arranged without wasting wiring.

FIG. 3 shows an enlarged cross section of the treading mat A. Insulating resin film layers 8 are formed on the upper and lower surfaces of the first wiring 4, the second wiring 5, and the conductor 3, respectively. First
The wiring 4, the second wiring 5, and the conductor 3 are formed of the resin film layer 8,
8 are integrated. Further, the upper resin film layer 8
The outer layers 9 and 9 made of rubber are formed on the upper surface side of the conductive rubber piece 2 and the lower resin film layer 8b. The material of the resin film layer 8 is preferably polyethylene terephthalate (PET), but other insulating resins may be used in some cases.

The upper resin film layer 8a has a hole 10
Is provided, and a pressurizing member G (pressurizing conductive rubber piece 2) is disposed in the hole 10. The pressurizing member G (pressurizing conductive rubber piece 2) protrudes above the upper surface of the upper resin film layer 8 a, and the pressurizing member G (pressing conductive rubber piece 2) and the outer layer 9 Thus, a convex portion 11 is formed.

As described above, the first wiring 4, the conductor 3, and the second
Since the resin film layers 8, 8 are formed on the upper and lower surfaces of the wiring 5, the outer layers 9, 9 are formed as shown in FIG.
When covering the whole with outer layer forming materials 17
That is, when the rubber molding is performed, there is no displacement of the wiring. Therefore, complicated wiring which has been difficult in the past can be realized. That is, the first wiring 4, the conductor 3, and the second wiring 5 can be wired so as not to short-circuit each other.

Further, according to the stepping mat A, the switch can be reliably turned ON only when a person stands on the stepping mat A.
It is possible to avoid the N state. Therefore, if the treading mat A is used as a sensor of an automatic door installed at the entrance of a building, the door is surely opened when a person passes, and even if a dog or cat comes in front of the door (the treading mat). Since the door does not open (even if it rests on A), the invasion of animals into the building can be reliably prevented. Further, even if the infant is placed on the treading mat A, it can be prevented from being turned ON, so that the infant does not unexpectedly go out of the building, which can contribute to prevention of accident of the infant.

In FIG. 3 and FIG.
6 and the wiring 4 (5), but in the present invention, as shown in FIG.
(5) may be separated. In that case, the pressure applying member G may not be made of the pressure conductive rubber, but may be made of a normal conductive material. However, the structure as shown in FIGS. 3 and 4 has higher productivity than the structure as shown in FIG.

[0020]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect of the present invention, since the pair of pressing members G of the treading switch unit U are turned on only when the pair of pressing members G are simultaneously pressed, the distance between the pressing members G, G is reduced. Is set according to the purpose, it is possible to detect only when a person steps on (becomes ON state), and not to detect when stepping on a small foot such as a dog or a cat. That is, it is possible to distinguish whether the stepping on the treading mat is a human or another animal.

According to the stepping pressure mat of the second aspect, the same effect as that of the first aspect can be obtained, and the ON state can be more reliably turned on when a person steps on the mat. When stepped on, it can be reliably maintained in the OFF state. Therefore, if the tread mat is used as a sensor for an automatic door at the entrance of a building, the invasion of animals can be prevented.
