DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment will be described as to how the pressure sensor according to the present invention is actually embodied.
FIG. 1 is a sectional view showing an embodiment of a pressure sensor according to the present invention.

Reference numeral 1 denotes, for example, a sponge-like soft sheet having a thickness of about 1 to 3 cm, which is insulative and has a large number of through holes 2 having a diameter of about 1 to 1.5 cm. The sponge-like soft sheet may be an ordinary sponge, but a soft and easily compressible sheet such as a sponge is preferred. The thickness may be 1 cm or less, but as the thickness is reduced, the size of the through hole 2 is preferably reduced. The through hole 2 is not limited to a circular shape.

Reference numerals 31 and 32 denote conductor sheets serving as a pair of counter electrodes. For example, a mesh formed by knitting a thin copper wire or the like into a sheet or cloth is suitable. Although not limited to a net, a flexible sheet that is easily deformed is suitable. The conductor sheets 31 and 32 are laminated on both sides of the sponge-like soft sheet 1.

Further, outside the conductive sheets 31 and 32,
Sponge-like soft sheets 41 and 42 which are insulators which easily deform like a sponge are laminated. And
On the outer surface of the lower sponge-like soft sheet 42, a sheet 5 made of raw rubber or synthetic resin is laminated and adhered as necessary.

On the outer surface of the upper sponge-like soft sheet 41, a foamed rubber or foamed resin sheet 6 is laminated and adhered as necessary, and a raw rubber or synthetic resin sheet 7 is laminated and adhered thereon. is there.

In this laminated structure, when pressure P is locally applied from the upper side, only that portion is applied to the raw rubber sheet 7,
The foamed rubber sheet 6, the sponge-like soft sheet 41, and the sponge-like soft sheet 1 are compressed, and as a result, the upper conductive sheet 31 is deformed downward and comes into contact with the lower conductive sheet 32.

Therefore, as shown in FIG. 2, when the power supply E and the indicator such as the lamp L are connected to the upper and lower conductor sheets 31 and 32 via the lead wires 81 and 82, the pressure is increased. Can be displayed by turning on the lamp L and can be visually confirmed.

As described above, the minimum necessary structure of the pressure sensor is as follows: a sponge-like soft sheet 1 having a large number of through holes 2, a pair of conductor sheets 31 and 32 for opposed electrodes laminated on both sides thereof; Outside the insulating sheets 41 and 42 are laminated for insulation.

However, although different depending on the place of use, it is more effective to further laminate an insulating rubber sheet or the like as shown in FIG. In addition, if the sheet of the laminated structure of the present invention is made larger, it can be used by cutting it with scissors or the like in a shape according to a place to be attached when used,
Can be easily applied to various places.

FIG. 3 shows an embodiment in which the pressure sensor shown in FIGS. 1 and 2 is mounted on a sports equipment. FIG. 3A shows a karate mask, and FIG. 3B shows a karate protector.

(1) In the case of the karate mask shown in the figure, a cushion material is attached to a position 9 corresponding to the forehead and a position 10 corresponding to the chin inside the mask body made of a rigid member, It has a buffer function. 1
Reference numeral 1 denotes a position corresponding to the eye, and the outside is visible by making a window hole or making it transparent.

Reference numeral 12 denotes a pressure sensor according to the present invention,
The pressure sensor of FIG. 1 is attached to the outside of the mask body near the face or nose. That is, the lower raw rubber sheet 5 shown in FIG. 1 is bonded and fixed to the mask body so that the upper raw rubber sheet 7 is exposed to the outside.

At the top of the head, an indicator lamp L and a battery E are mounted, and are connected between a pair of conductive sheets of the pressure sensor 12 via a lead wire. Accordingly, when the opponent's limb hits the pressure sensor 12 corresponding to the face during the match, the pressure at that time causes the pair of conductive sheets to come into contact with each other and to be electrically connected, so that the lamp L is turned on and the face is touched. The hit is displayed, and it is possible to immediately and accurately determine that the opponent has fouled.

(2) In the protector for protecting the body shown in the figure, a suspending band is provided at the upper end of the protector body 13 to be connected to each other by being turned from the front to the back of the neck, and to have fasteners 14a and 14b at the upper end. ing. Also, it has fasteners 15a and 15b that are turned around the trunk and connected to each other behind the waist. The pressure sensor 16 shown in FIG. 1 is attached to the outside of the body of the protector body 13. That is, the lower raw rubber sheet 5 shown in FIG. 1 is adhered and fixed to the protector body 13 and the upper raw rubber sheet 7 is mounted so as to be exposed to the outside.

In the vicinity of the fastener 14b at the upper end of the suspension band, a display lamp L is mounted on the front side, and a battery is mounted inside. A lead wire is provided between the pair of conductive sheets of the pressure sensor 16 described above. It is electrically connected via

Therefore, when the opponent's limb hits the pressure sensor 16 corresponding to the torso during the match, the pressure at that time causes the pair of conductive sheets to come into contact with each other and become electrically conductive, so that the lamp L is turned on. Is displayed, and it can be determined that the opponent has fouled.

Although the illustrated embodiment is an example in which the pressure sensor of FIGS. 1 and 2 is mounted on a karate device, it goes without saying that the present invention can also be applied to a kendo device and other various motion devices.

FIG. 4 shows an embodiment in which the pressure sensor shown in FIGS. 1 and 2 is mounted on a strike zone judging device for pitching practice in baseball. (1) is a front view, and (2) is a left side view. is there. For example, with a square plate 17 attached to a support frame 18, the plate 17 is supported from behind by a catching bar 19 and is held substantially vertically.

Although the pressure sensor of FIG. 1 is mounted on the plate 17, in this embodiment, two pressure sensors are provided.
It is mounted in four areas 0a to 20d. For example, assuming that a region surrounded by a rectangular chain line 21 is a strike zone and the outside thereof is a ball zone, first, the pressure sensor shown in FIG. 1 is cut into the shape of a ball zone, and pasted on the surface of the plate 17 like 20a. Yes, the conductor sheet is connected to the lamp L1 by a lead wire C1.

Next, in the strike zone, for example, three corners 20b, 20b, 20b
Three pressure sensors are attached, and each conductive sheet is connected to the lamp L2 by a lead wire C2.

Further, in the strike zone, pressure sensors 20c, 20c, 20c having shapes corresponding to the three regions between the corners 20b, 20b, 20b are cut out and pasted. Each conductive sheet is connected to the lamp L3 by a lead wire C1.

Further, a pressure sensor 20d cut into a shape corresponding to the central area where the batter is most likely to hit in the strike zone is attached, and the conductive sheet is connected to the lamp L4 by a lead wire C1. Power supply E
Is commonly connected to all the lamps L1 to L4, but the circuit between the other conductive sheet of each pressure sensor and the power supply E is not shown. Note that the lamps L1 to L4 have different colors.

Each of the pressure sensors 20a to 20d is attached so that the lower raw rubber sheet 5 on the lower side of the pressure sensor in FIG. 1 is bonded and fixed, and the upper raw rubber sheet 7 is exposed to the outside. And if you draw a picture of the catcher on it, it will be closer to the real thing.

In this strike zone determiner, if the ball hits the center of the strike zone now,
Although the pair of conductive sheets of the pressure sensor 20d are in contact with each other, the lamp L4 is turned on, and although it is a strike,
It is displayed that you have come to the center where the batter can easily hit.

When the ball hits the corner which is least hit by the batter, the pair of conductive sheets of the pressure sensor 20b are brought into contact with each other and the lamp L2 is turned on. As a result, it is displayed that the strike has occurred and that the vehicle has come to the corner.

In this way, the conductive sheets of the pressure sensors 20a to 20d at the position where the ball has arrived and hit are turned on, and the corresponding lamps L1 to L4 are turned on to indicate the position where the ball hit. Therefore, the position where the ball comes can be accurately and easily visually determined.

It is to be noted that a sound generator that utters a "ball" is connected in parallel with the lamp L1, and the other lamps L2 to L
If a voice generator that utters “strike” is connected in parallel with 4, the ball can be distinguished from the strike by voice. Also, in the same strike, the sound generator on the side of the lamp L4 that displays the center emits a weak voice, and the side of the lamps L2 and L3 that indicates that the vehicle has come to a zone where a batter is difficult to hit, such as a corner, It is also possible to connect a sound generator that utters with a vigorous voice.

The place of use of the apparatus of FIG. 4 is not particularly limited, but by providing this apparatus, the "pitching center"
A new kind of game hall can be opened. FIG. 4 shows an example used for the strike zone determination in baseball.
The present invention is not limited to this, and can be used for, for example, a device for determining the arrival position of a golf ball, tennis practice, and the like.

As shown in FIG. 4, the idea of dividing a position hit by a ball or the like into a plurality of areas, mounting a pressure sensor separately for each area, and independently connecting display means is as shown in FIG. Needless to say, it can be applied to the brace.

As described above, the pressure sensor of the present invention
Although it can be used in various places, the pressure sensor of FIG. 1 can be variously changed depending on the place of use. In a place where a cushioning action is required, as shown in FIG. 1, it is effective to stack thick sponge-like soft sheets 41 and 42 on both sides of the sponge-like soft sheet 1 having the through-holes 2. The sponge-like soft sheet 42 can be omitted. Also, the upper side may be made of only one of the sponge-like soft sheet 41 and the foamed rubber sheet 6.

The conductor sheets 31 and 32 for the counter electrode are also
In some cases, only the upper side needs to be flexible. In that case, a mesh-shaped conductor sheet 31 is provided only on the upper side, and a metal plate or a metal foil can be used instead of the lower conductor sheet 32. A double-sided adhesive tape or the like may be attached to the lower rubber sheet 5 in advance.
