Description

  The present invention relates to a torso protection armor used for protecting a torso by attaching it to a torso of a player in a battle-type competition such as a batting type martial art, an armor cover to be used for the torso protection armor, and using these This invention relates to a batting determination device that determines whether the batting is effective or invalid.

  Traditionally, traditional Japanese martial arts such as Kendo, Karate, and Aikido have been known, as well as various battle-type competitions such as Cotendo, Kung Fu, kickboxing, boxing, and fencing. In this type of competition, a trunk protection armor or the like is often worn to prevent the trunk including the abdomen of the athlete from being hit directly. Moreover, the armor with which a head, a hand part, etc. are mounted | worn is also known.

  In this type of competition, an accurate determination may be difficult because the batting is instantaneous. In addition, it may be difficult to accurately determine whether the hit is valid or invalid. Furthermore, there are competitions in which an attack on an eyeball or a critical point is judged to be a foul or to be effective, and particularly when it is effective, an armor for protecting the player from this attack is necessary.

JP-A 64-34385 JP-A-63-240890 Japanese Utility Model Publication No. 6-11171 JP 2000-42162 A JP 2003-38703 A JP-A-7-51424

  Patent Documents 1 and 2 describe that a sensor is provided on the wrist to detect that there is a “thrust” or “kick” in violation of the so-called sizing rules in karate competition and issue a warning. Yes. Patent Document 3 provides a hitting sensor for both the defense armor and the attacking attacking tool. When there is no output from one of the sensors, it is determined that there is no hitting and is effective only when both sensors detect hitting. It is described that determination is made to prevent erroneous determination.

  In Patent Document 4, different electrodes 4 and 5 are arranged on the body protection armor 1 and the like with a gap between them, and an effective hit detection sensor 6 is formed by these electrodes 4 and 5, and the surface of an attacking glove is electrically conductive. A device is described that is equipped with a body and detects an effective blow by conducting the electrodes 4 and 5 when the glove contacts the armor of the opponent.

  Patent Document 5 discloses an impact determination system using an effective strike detection sensor for detecting the position and strength of an effective strike using a kendo armor or the like. Patent Document 6 discloses that a determination device 10 is provided on the waist of a fencing player to detect an effective hit and turn on a light emitting diode.

  Since those described in Patent Documents 1 and 2 are provided with a hitting sensor on the wrist of the athlete, it is necessary to provide not only the sensor but also a signal processing circuit and a transmission circuit on the wrist, thereby preventing the athlete from attacking. There is a problem that it can be an obstacle to operation. There is also a problem that when one of the competitors hits the ball without stopping, the other player cannot be safely protected from the hit. In Patent Documents 3, 4, and 6, it is necessary to provide a sensor or a sensor and a conductive jacket on the armor and the striking device (glove, sword) worn by both players, and the entire apparatus becomes complicated.

  In Patent Document 5, an effective hit detection sensor such as a membrane switch is arranged directly under the surface of a head or neck armor, a chest or abdominal armor, a waist or thigh armor, a fist or a wrist armor, etc. In addition, it is described that the signal of this sensor is wirelessly transmitted to the determination circuit to perform the hit determination. Since this hit detection sensor is disposed immediately below the surface of a predetermined portion of the armor (see paragraphs 0013 and 0022), it is necessary to sew it into a dedicated armor in advance, for example.

  For this reason, the armor to which this effective hit detection sensor is attached cannot be used in a normal competition or practice that does not require this sensor. Therefore, there is a problem that it is necessary to prepare both the armor to which the sensor is attached and the normal armor to which the sensor is not attached.

    The present invention has been made in view of such circumstances, and eliminates the need for attaching another sensor or electric circuit to the attacking part such as the wrist of the athlete or the armor such as the sword held in the hand. It eliminates the danger of disturbing the defensive action, and even if one of the competitors hits the opponent accidentally against the sizing rules etc., it is possible to protect the player from this hit, and no further hit sensor is required It is a first object of the present invention to provide a body protection armor that can be easily removed and played using only a normal body protection armor body. It is a second object of the present invention to provide an armor cover used for the body portion protection armor. It is a third object of the present invention to provide an impact determination device using the trunk protection armor.

  According to the present invention, a first object is a torso protection armor to be mounted on a torso by a player of a battle-type competition, and the torso armor body that covers at least the torso front surface of the athlete, and the torso armor A body protection armor comprising: a armor cover made of a flexible sheet that is detachably attached to the front surface of the main body; and a batting sensor that is attached to the armor cover and detects a batting on the body. Is achieved.

  The second object is a protective armor cover that is detachable on the front surface of a body armor body that is worn by a contestant and is equipped with a batting sensor that detects the batting on the body. To be achieved. A third object of the present invention is the impact determination device using the trunk protection armor according to claim 1, and a determinator that determines the effectiveness of the impact based on the output of the impact sensor provided in the trunk protection armor; This is achieved by a batting judgment device comprising a batting notice means for notifying the judgment result.

  Since the 1st invention attached the hit | damage sensor which detects the hit | damage to a trunk | drum to the armor cover which consists of a flexible sheet | seat detachably attached to the front surface of a trunk | drum armor main body, attack parts, such as a player's wrist There is no need to attach a separate sensor or electric circuit to the armor such as a sword held in the hand, and there is no risk of obstructing normal attack defense operation. Also, even if one of the competitors hits the opponent accidentally against the dimension stop rule, etc., it is possible to absorb the hit with the body protection armor body and protect the player from this hit, and further need a hit sensor If not, you can easily remove it and play using only the normal body protection armor body. For this reason, it is not necessary to prepare armor with an impact sensor and armor without an impact sensor separately.

  According to the second aspect of the present invention, an armor cover used for the body protection armor is obtained, and the impact on the body is detected by the impact sensor by attaching the armor cover to the normal body protection armor without the impact sensor. It becomes possible, and if the armor cover is removed, it can be returned to the normal body protection armor without using the impact sensor. According to the third aspect of the invention, it is possible to determine the validity / invalidity of the hitting with the determiner using the hitting sensor output of the abdominal protection armor, and thus it is possible to reliably prevent erroneous determination. Further, the determination result can be immediately notified to the umpire by means of an indicator lamp, a signal sound, etc. by the batting notification means, so that the game can proceed smoothly.

  The impact sensor can be attached to the surface of the armor cover facing the body side of the armor, and held between the armor body surface. It is possible to detect a hit by being sandwiched between the body protection armor body surface having a sufficient strength and hardness, and the detection accuracy is improved. At this time, depending on the type of sensor, it is possible to determine not only the presence / absence of an impact, but also the impact pressure.

  A resin foam having low resilience and moderate shock absorption is preferably interposed between the impact sensor and the body protection armor body (Claim 3). As the resin foam used here, for example, “EXGEL” (registered trademark) supplied from Kachi Co., Ltd. is suitable. By interposing such a resin foam, the impact force applied to the armor cover is diffused to the armor cover, and when the resin foam hits the armor body surface, the contact pressure is dispersed by the resin foam and accurately transmitted to the impact sensor. be able to.

  Therefore, even if a plurality of impact sensors are arranged apart from each other, impacts applied between them are detected by the plurality of impact sensors, and the impact can be detected with high accuracy. In this case, it is possible to accurately detect the striking force by accurately calculating the striking force by performing a calculation such as addition by a determinator described later on the detection outputs (pressures) of the plurality of striking sensors. Such a determiner is preferably composed of a computer (PC).

  For example, a pressure-sensitive conductive elastomer sensor covered with a dome-shaped rubber cover is suitable as the plurality of impact sensors. As this sensor, for example, “Inastomer” (product name) supplied from Inaba Rubber Co., Ltd. is suitable. This sensor is molded in a state in which conductive particles are dispersed almost uniformly in an insulating rubber material, and the conduction path of the conductive particles increases and the electric resistance value decreases as the applied pressure increases. The dome-shaped rubber cover protects the sensor by reducing the impact impact applied to the sensor.

  If a plurality of (for example, four) batting sensors are attached so as to surround the abdomen of the competitor, the striking force applied to the abdomen is detected by a plurality of sensors surrounding the abdomen, and the outputs are summed up. By performing the processing, it is possible to detect an accurate hitting force and hitting position. Therefore, in this case, accurate detection is possible with a small number of impact sensors.

  The armor cover according to claim 6 is formed of a flexible sheet having an appropriate hardness, and if a plurality of hitting sensors are attached to the back surface, hitting can be determined using the outputs of the plurality of hitting sensors, and the determination accuracy. Will improve. In the hit determination device of claim 7, the hit notification means may be a light emitting display means provided on the armor body (claim 8). For example, it is conceivable to use a head protection armor that protects the head together with the body portion protection armor of the present invention, and the light emitting display means can be provided in the head protection armor. In this case, it is preferable to attach the LED light emitting element near the top of the head protection armor. This is because it consumes less power and is easily visible from the surroundings.

  The striking notification means may be one that notifies by a sound device such as a buzzer. It is better to change the sound quality of the buzzer etc. according to the effectiveness of the impact and the location of the impact. You may use both this acoustic apparatus and the said light emission display means together.

  The judgment device and the batting notification means are installed away from the competitor, for example, in a place where the judges can easily recognize, and the output of the batting sensor can be transmitted wirelessly from the transmitter attached to the competitor to the judgment device. (Claim 9). In this case, the competitor only needs to wear a sensor output transmitter, so it does not interfere with the competitor's competition.

  The judging device and the batting notification means may be attached to the athlete. In this case, the batting notice means may be attached to the head protection armor so as to be easily recognized by the competitors, the judges, and the audience. (Claim 10). In this case, it is possible to make the spectator particularly enjoyable.

  1-4, the code | symbol 10 is a head protection armor used with this invention. This head protection armor 10 covers the competitor's head 12 almost entirely except for the front (face) to protect the head 12, and the face exposure opening that exposes the front face forward on the front. The armor main body 16 in which 14 is formed, and the front board 18 made from a hard transparent resin which covers this face exposure opening part 14 from the front are provided. Needless to say, the lower surface of the armor body 16 is opened to allow the head 12 to enter from below.

  The armor body 16 is provided with a plate-like cushioning material 20 for softly protecting the head 12 on the entire inner surface, and ring-like cushioning materials 22 (FIG. 4) for protecting the athlete's ears are attached to the left and right side surfaces. Yes. On the outer surface of the armor body 16, a band-shaped cushioning material 24 is wound and fixed obliquely from the upper front part to the lower rear part to absorb the impact on the upper surface of the head. 3 and 4, reference numeral 25 denotes a band for holding the head protection armor 10 on the head 12, which is fastened from the rear portion of the cushioning material 24 to the jaw of the head 12.

  As shown in FIGS. 3 and 4, the front plate 18 is formed in a substantially mask shape that covers the face exposure opening 14 of the armor body 16, and its outer peripheral edge is formed on the outer peripheral edge of the face exposure opening 14 from the outside. It adheres and is fixed in this state. That is, the string 26 is bound through the string holes respectively drilled at the corresponding positions. Therefore, the armor body 16 and the front plate 18 are integrated to form the armor body 16.

  As shown in FIGS. 3 and 4, the front plate 18 has a horizontally long view securing opening 28 facing the front of the athlete's eyeball, a substantially triangular nasal opening 30 facing the athlete's nose, A pair of left and right mouth openings 32 facing the athlete's mouth is formed.

  In front of the front plate 18, there is attached a flexible transparent protective plate 34 that covers the entire visual field opening 28 and nasal opening 30 and the upper half of the mouth opening 32 from the front. It has been. The transparent protective plate 34 is detachably attached to the armor body 16 with an appropriate gap between the transparent protective plate 34 and the front plate 18. That is, the left and right side portions of the transparent protective plate 34 are detachably attached to the armor body 16 using the resin binder 36 (FIG. 3).

  A plurality of impact sensors 38 are mounted between the front plate 18 and the transparent protective plate 34. That is, a pair of left and right rubber-like elastic members 40 are bonded and fixed above the upper edge of the visual field securing opening 28 of the front plate 18 at an appropriate interval, and below this and on the upper edge of the visual field securing opening 28. The impact sensor 38 is fixed in the vicinity (FIG. 3). Further, another impact sensor 38 is fixed between the center of the lower edge of the visual field securing opening 28 of the front plate 18 and the nasal opening 28.

  As these impact sensors 38, for example, “Inastomer SFR type”, which is a pressure-sensitive conductive elastomer sensor provided by Inaba Rubber Co., Ltd., is suitable. Here, it is preferable that the impact sensor 38 protects the impact sensor 38 by adhering and fixing a dome-shaped rubber cover to the upper surface of the impact sensor 38 to mitigate impact of the impact.

  Thus, by combining the hard front plate 18 and the transparent protective plate 34 having flexibility and shape restoration property, the transparent protective plate 34 is deformed by impact, and the impact sensor 38 is activated by this deformation, and the transparent protective plate 34 is also activated. The hitting sensor 38 can be returned by restoring the transparent protective plate 34 by its own restoring force and the restoring force of the elastic member 40 and returning it to the correct position. Accordingly, the impact sensor 38 can be accurately operated with a simple configuration.

  As shown in FIG. 1, a head protector 42 that hangs from the neck to the shoulder of the athlete and a throat protector 44 that extends from the chin to the front of the neck are preferably attached to the head protector 10. The head protection armor 10 can be used in combination with the body protection armor 46 that protects the athlete's chest and abdomen, the crotch region protection device 48 that protects the crotch, or the foot shin armor 50. In this case, hitting sensors 52, 54, and 56 are provided on the armors 46, 48, and 50, and the hitting at each position is detected together with the hitting sensor 38.

  Next, the body protection armor 46 will be described with reference to FIGS.
