The above conventional rugby practice equipment has a point that should be improved in the practice of scenes involving hard contact play such as tackling.
The first exercise for effective tackling is for the defending player to tackle an attacking player who is moving forward with the ball in the lowest position possible. In other words, it is necessary for the defending player to practice the so-called "hit" of a tackle, in which the player steps into the feet of the attacking player and vigorously hits the attacking player with his shoulder from the waist down. Offense and defense Conversely, the attacking player with the ball needs to practice taking tackle "hit" in such a low position.
Scenes that mainly involve the "hit" of a tackle are hard contact play in which players collide directly with each other. If you don't get used to it, you will get hurt.
A second practice for effective tackling is for the tackling defensive player to perform a so-called "bind" in which both arms are wrapped around the hips and thighs of the offensive player who has the ball. In other words, it is necessary for the defensive players to practice effective "bind" in which both arms sandwich the hips and thighs so as to block the movement of the offensive players. The most effective defense is to firmly bind the back of the opponent's thighs with both arms and push them in, lifting the center of gravity of the offensive player who has the ball and causing him to flip over and drop from his back or hips. . Offense and Defense Conversely, for the attacking player who has the ball, it is necessary to learn how to deal with a defense involving such a "bind" tackle and how to fall safely.
The tackling scene, which is mainly based on this "bind", is a hard contact play in which the attacking player with the ball is turned over by the tackle and hits the ground from the back, waist, or head, and is moving forward with the ball. If the player who receives the tackle does not practice enough and get used to it, he will get injured.
In particular, the impact of hitting the back of the head against the ground is dangerous, and it is important to learn how to protect the back of the head as a countermeasure against defense that involves a tackle "hit" or "bind". Even if you suppress the impact of each practice by wearing the , the damage accumulated by repeating the practice many times will increase, so you have to protect it sufficiently. In addition, since the headgear can only protect the back of the head, it cannot effectively absorb the impact of the head falling on the neck, which may damage the cervical vertebrae.
Of course, the impact of hitting the ground against the back or waist is also dangerous, and in the worst case, a serious accident that interferes with walking can occur. The players on the defensive side who make tackles have to be aware of this, and even if it is practice, they cannot sufficiently practice bind tackle against real players.
Using effective rugby practice equipment, whether you are an offensive player who has the ball or a defensive player who stops it, you can firmly practice the first and second tackling exercises as described above. It is necessary to learn and reduce injuries and damage.

In view of the above problems, looking at the above-described conventional techniques, there are points to be improved in any of the conventional rugby practice tools of Patent Documents 1 to 6.
The practice tools disclosed in Patent Document 1, Patent Document 2, and Patent Document 3 are so-called tackle dummies, and are useful for the training of defensive players who tackle. However, it is not possible to practice a player moving forward with the ball to receive a tackle. It is not useful for improving the ability of attacking players to receive tackles.
Patent Document 4 is a so-called body suit type protector, and by wearing it, even if it is an attacking player who has the ball or a defending player who stops it, it is possible to prevent the tackle "hit". It can be said that it plays a certain role in the sense of buffering external force. However, as shown in FIG. 12, a cushioning material is placed on the front surface to cushion the external force generated at the direct contact points between the players when the tackle "hit", but the "bind" that may occur after that. ” cannot sufficiently respond to the impact of hitting the ground from the player's head, back, and hips.
The practice equipment shown in Patent Documents 5 and 6 is a so-called bodysuit type protector, and by wearing it, even if an attacking player has the ball, it becomes a defending player to stop it. However, it can be said that it plays a certain role in the sense of buffering the external force when the tackle "hit". However, as shown in Figures 13 and 14, the cushioning material is mainly placed on the front side, and can cushion the external force generated at the direct contact points between the players when the tackle "hit". There is not enough consideration for the impact of a tackled player hitting the ground from the head, back and hips associated with a possible "bind". In addition, the practice tools shown in Patent Documents 5 and 6 do not have a structure that protects the back of the head. It cannot effectively cushion the back of the head when it falls, and it can also damage the cervical vertebrae.

In order to solve the above-mentioned problems, the main object of the present invention is to sufficiently absorb the damage caused by the "bind" of the tackle to the tackled player, especially the impact of hitting the ground from the head, back, and hips. , It sufficiently buffers and protects the damage of the player who receives the tackle, which was not sufficient with conventional headgear and body suit type protectors, and the defense side player who tackles does not have to worry about unexpected accidents, and is a real practice opponent. To provide a back protector for rugby practice, which enables a player to practice "hit" and "bind" tackles in minutes.

The back protector for rugby practice according to the present invention comprises a back protector having a size that covers the wearer's back from the back of the head to the back and hips while exposing the thighs, and a back protector filled inside the back protector. Equipped with a cushioning material and a mounting tool for fixing the back protector to the back of the wearer carrying the back protector, the back protector is worn by the wearer so as to be carried on the back, and the back of the head to the waist is protected even if the wearer falls backward. A back protector for rugby practice characterized by:
The attaching tool may be anything as long as it fixes the back protector to the back of the wearer carrying the back protector, and the location of attachment is not limited.
For example, the attachment tool is attached to the back protector at a height near the armpit of the wearer from a shoulder attachment point of the back protector at a height near the upper shoulder of the wearer carrying the back protector on the back. "Right shoulder belt and left shoulder belt", which are two belts on the left and right that are obliquely provided up to the armpit attachment point and can be worn by the wearer on the left shoulder and the right shoulder, respectively, and the back protector. A band provided laterally from one abdominal attachment point to the other abdominal attachment point of the back protector at a height near the abdomen of the wearer carrying the wearer on the back, and can be hung on the abdomen of the wearer. There is a pattern with a "girdle body".
Further, for example, the attachment tool is a band provided laterally from one chest attachment point of the back protector to the other chest attachment point at a height near the armpit of the wearer carrying the back protector on the back. A "chest belt" that the wearer can hang on the chest near the armpit, and one abdominal attachment of the back protector at a height near the abdomen of the wearer carrying the back protector. There is a pattern with a "belly girdle", which is a band that extends laterally from one point to another abdominal attachment point and that the wearer can wear across his abdomen.
Of course, it is also possible to have a structure having three members of "right and left shoulder girdle", "thoracic girdle" and "abdominal girdle".
With the above configuration, it is possible to sufficiently absorb the damage to the tackled player due to the "bind" of the tackle, especially the impact of hitting the ground from the head, back, and hips. In particular, it can protect the neck, shoulders, back, and waist from the back of the head at the same time, and can effectively soften the impact of the back of the head falling with the neck as a fulcrum, which was insufficient in Patent Documents 5 and 6. It can also protect the cervical vertebrae sufficiently.

Here, in the configuration of the back protector for rugby practice, the length of each of the right shoulder girdle and the left shoulder girdle can be adjusted, and the two can be separated or joined together. The structure is provided with a detachable release buckle for the shoulder belt body, and in particular, the disposition position of the detachable release buckle is set near the attachment point under the armpit of the wearer.
Similarly, in the case of a configuration in which a chest strap is provided, the length of the strap can be adjusted, and the configuration is provided with a chest strap detachable release buckle that can separate or connect the strap in two, In particular, the chest band detachable release buckle is located near the armpit mounting position, and the chest band detachable release buckle is not located on the wearer's body surface side and does not contact the wearer's back. preferably in
As for the abdominal band, the length of the band can also be adjusted, and the structure is provided with an abdominal band detachable release buckle that can separate or connect the band in two. It is preferable that the installation position is near one or other attachment points on the abdomen, and that the abdominal band release buckle is not located on the wearer's body surface side and does not come into contact with the wearer's back surface.

Even if the material of each removable release buckle, such as the shoulder girdle release buckle, the abdominal girdle release buckle, and the chest girdle release buckle, is made of a relatively soft resin material, it is possible to reduce the impact of "hit" when athletes collide with each other during tackle practice. It can be a dangerous member at times, and it can also be a dangerous member at the time of "binding" when the wearer who is tackled may be hit on the ground. Each detachable release buckle is not located on the wearer's body surface side, and can be installed in a position that does not contact the wearer's back. The wearer will not come into contact during a ``bind'', which could cause the wearer to be slammed into the ground. By providing each detachable release buckle, the length of the strap can be appropriately adjusted, unnecessary play between the wearer wearing the back protector for rugby practice of the present invention and the back protector for rugby practice is eliminated, and , and inappropriate squeezing.
Various types of detachable release buckles are possible. Although not particularly limited, a detachable detachable release buckle that can be easily connected and detached is preferred. A material made of resin is preferable. For example, if one of the resin fittings is pushed into the other resin fitting, the claws will be engaged and can be connected. .

Next, in the structure of the back protector for rugby practice, the back protector is provided with a plurality of ventilation holes on the sides and upper and lower surfaces of the back protector for ventilation of the air generated by the deformation of the cushioning material inside. It is preferable to set it as a structure.
With the above configuration, the cushioning performance of the back protector is improved by deforming the cushioning material inside the back protector, but without ventilation, the cushioning material inside the back protector responds quickly and is difficult to deform. Where the high cushioning performance of the back protector cannot be obtained, if there are ventilation holes for air ventilation on the sides and top and bottom surfaces, ventilation can be performed sufficiently and the high cushioning performance of the back protector can be obtained. be done. If the ventilation hole is on the front, it may be sealed to the wearer's body, and if the ventilation hole is on the back, it may be sealed to the ground, but if it is on the side, it will hinder ventilation. There is no

Next, it is preferable that the back protector has a bent portion that can be bent in the front-rear direction of the wearer. For example, the back protector includes an upper body area that protects the wearer's back from the back of the head, and a lower body area that protects the waist of the wearer, and the upper body area and the lower body area are connected by a folding portion so as to be bendable. do.
With the above configuration, the back surface protector is bent by the bending portion according to the forward leaning posture of the wearer and has a shape that conforms to the wearer's body. The back protector is large enough to cover the back of the wearer's head, back, and hips. If the back protector is foldable, the wearer can easily take a forward leaning posture. .
Next, the material of the back body surface is not particularly limited, but examples thereof include artificial leather, natural leather, tarpaulin, polyester cloth, and vinyl chloride cloth.
Next, the material of the cushioning material is not particularly limited, but for example, a foam, a mold-like body, or a bead aggregate of interconnected cells composed of silicone, polypropylene, or polyurethane resin, or a laminated aggregate of cotton is used as the material. things are preferred.
If these materials are used to fabricate the back protector, it will be strong, hard to tear, lightweight, and will have excellent shock-absorbing properties and durability.

The back protector for rugby practice of the present invention can sufficiently absorb the damage caused by the "bind" of the tackle to the tackled player, especially the impact of hitting the ground from the head, back and hips. It can protect the back of the head, neck, shoulders, back, and hips at the same time, and can effectively soften the impact of the back of the head when the neck is the fulcrum, and can also protect the cervical vertebrae.

An embodiment of a back protector for rugby practice according to the present invention will be described below. It should be noted that the following embodiments are merely examples and do not limit the technical scope of the present invention.

The rugby practice back protector 100 according to the first embodiment of the present invention is worn by the wearer so as to be carried on the back, and is characterized by protecting the back of the head to the waist even if the wearer falls backward. is. Shows the basic type.
A rugby practice back protector 100 basically includes a back protector, a cushioning material, and a fixture.
Here, the attachment is a member for fixing the back protector to the back of the wearer carrying the back protector on her back, and there may be various types of attachments. It is an example provided with a belt body and an abdominal band body.
FIG. 1 is a diagram simply showing the structure of a rugby practice back protector 100 of the present invention according to a first embodiment.
The rugby practice back protector 100 according to the first embodiment shown in FIG. ing.

The back protector 110 is a structure having a size that covers the back of the head, the back, and the waist of the wearer 200 and exposes the thighs, and is the main body of the protector that protects the wearer 200 .
The surface material 111 of the back protector 110 is not particularly limited, but examples thereof include artificial leather, natural leather, tarpaulin, polyester cloth, and vinyl chloride cloth. These materials are durable and tear resistant.

The interior of the back protector 110 is filled with a cushioning material 120 to provide cushioning properties. Even if the wearer 200 falls backward, the wearer 200 can be safely received, and the impact force applied to the wearer 200 can be dispersed.
The material of the cushioning material 120 is not particularly limited. It is preferable to use a laminated assembly as a material.

In this configuration example, a plurality of ventilation holes 112 are provided on the side surface and the upper and lower surfaces of the back protector 110 so that ventilation can be performed to immediately adjust the blowout of air generated by the deformation of the cushioning material 120 when the wearer falls down. ing. In this example, five each are provided along the side surface and the upper and lower surfaces of the back protector 110 in a well-balanced manner. Without this ventilation hole 112, the wearer could not immediately respond to the blowout of air generated by the deformation of the cushioning material 120 when the wearer fell down, and the pressure inside the back protector 110 would not be reduced, resulting in a high repulsion, and on the contrary, the cushion would rebound. damage may occur.
The appropriate diameter of this ventilation hole 112 is about 5 mm to 1 cm. If the diameter of the ventilation hole 112 is too large, pebbles or foreign matter may enter through the ventilation hole 112, and there is a risk that a hard portion will be formed in a part of the back protector 110. FIG. If the diameter of the ventilation hole 112 is too small, the ventilation will not function sufficiently, and the internal pressure of the back protector 110 will not be reduced, resulting in high repulsion.

Next, the left shoulder girdle 130 and the right shoulder girdle 140 will be described. The left shoulder girdle 130 and the right shoulder girdle 140 form a left and right pair. The right shoulder girdle 140 is similar to the left shoulder girdle 130 except that the right and left shoulder girdle bodies 140 are different.
The left shoulder belt 130 is a belt having one end provided at an upper shoulder mounting point 131 and the other end at an underarm mounting point 132 on the surface of the back protector 110 and extending between them.
The upper shoulder mounting points 131 are provided on the surface of the back protector 110 at a height near the upper shoulders of the wearer 200 carrying the back protector 110 on the back.
The armpit attachment points 132 are provided on the surface of the back protector 110 at a height near the armpits of the wearer 200 carrying the back protector 110 on the back.
In this example, the strap itself is divided into two pieces, an upper left shoulder strap 130-1 and a lower left shoulder strap 130-2, which are connected via a left shoulder strap detachable release buckle 133. FIG. That is, the upper left shoulder girdle 130-1 is passed from the upper shoulder attachment point 131 to the left shoulder girdle release buckle 133, and the lower left shoulder girdle 130-2 extends from the left shoulder girder release buckle 133 to the armpit. It is passed over the attachment point 132 .

Here, in this example, as shown in FIG. 1, the arrangement position of the left shoulder strap detachable release buckle 133 and the length of the lower left shoulder strap 130-2 are devised. The lower left shoulder girdle 130-2 is short, and the left shoulder girdle detachable release buckle 133 is provided near the armpit attachment point 132. As shown in FIG. With this ingenuity, the left shoulder belt detachable release buckle 133 is devised so that it is not positioned on the body surface side of the wearer 200 and is not in contact with the back surface of the wearer 200 . In other words, the left shoulder girder release buckle 133 and the right shoulder girder release buckle 143 do not injure the wearer 200 in the hard contact play of tackling. The buckle 133 and the right shoulder strap detachable release buckle 143 do not hit each other.

The left shoulder girdle detachable release buckle 133 can adjust the connection length of the upper left shoulder girdle 130-1 and the lower left shoulder girdle 130-2 that are connected to each other. 130-2 can be separated into two or can be connected together. In this example, the length of the upper left shoulder girdle 130-1 is sufficiently long, and the length can be adjusted by inserting it into the slit of the left shoulder girdle detachable release buckle 133 and folding it back.
As shown in FIG. 1, in this example, due to the positional relationship between the upper shoulder attachment point 131 and the lower armpit attachment point 132, the left shoulder belt 130 is a belt extending obliquely across the vicinity of the left shoulder. It can be fastened to the left shoulder by tightening it via the left shoulder belt detachable release buckle 133.

There are various types of detachable release buckles, and they are not particularly limited, but a detachable release buckle that allows easy connection and disconnection is preferable. A material made of resin is preferable. For example, if one of the resin fittings is pushed into the other resin fitting, the claws will be engaged and can be connected. be. FIG. 1 illustrates a so-called side release buckle.

Next, on the surface of the back protector 110, the abdominal band member 150 is a belt member provided with one end at the right abdominal attachment portion and the other end at the left abdominal attachment portion, and spanned between the two.
The right abdomen attachment point and the left abdomen attachment point are provided on the surface of the back protector 110 at a height near the abdomen of the wearer 200 carrying the back protector 110 on the back.
In this example, the band itself is divided into two pieces, a right abdominal band 150-1 and a left abdominal band 150-2, which are connected via a release buckle 153 for detachment of the abdominal band. In other words, the right abdominal band 150-1 extends from the right abdominal band to the abdominal band detachable release buckle 153, and the left abdominal band 150-2 extends from the abdominal band removable release buckle 153 to the left abdominal band. It is

Here, in this example, as shown in FIG. 1, the arrangement position of the abdominal band detachable release buckle 153 and the length of the left band 150-2 are devised. The left abdominal band 150-2 is short and the abdominal band detachable release buckle 153 is provided near the left abdominal attachment point. With this ingenuity, the abdominal band body detachable release buckle 153 is not positioned on the body surface side of the wearer 200 and is arranged so as to be hidden in a position where it does not contact the back of the wearer 200, for example, near the abdominal side of the armpit. It is devised to In other words, the abdominal band detachable release buckle 153 does not hurt the wearer 200 in the hard contact play of tackling, and the abdominal band detachable release buckle 153 does not hit the player who tackles.

The abdominal band detachable release buckle 153 can adjust the connection length of the connected right abdominal band 150-1 and left abdominal band 150-2, and divides the right abdominal band 150-1 and the left abdominal band 150-2 into two. It can be separated or linked together. In this example, the length of the right abdominal band 150-1 is sufficiently long, and the length can be adjusted by inserting it through the slit of the removable release buckle 153 and folding it back. Also, the length of the left abdominal band 150-2 is sufficiently short, and the abdominal band detachable release buckle 153 is arranged so as to be hidden in the gap of the left abdomen.
As shown in FIG. 1, in this example, due to the positional relationship between the attachment point on the right side of the abdomen and the attachment point on the left side of the abdomen, the abdominal band 150 is a band extending laterally across the vicinity of the abdomen. It has a shape that is easy to hang and can be fastened to the belly.
As with the left shoulder girdle release buckle 133 and the right shoulder girder release buckle 143, there are various types of the abdominal girdle release buckle 153, which are not particularly limited. A release buckle is preferred. A material made of resin is preferable. For example, if one of the resin fittings is pushed into the other resin fitting, the claws will be engaged and can be connected. . FIG. 1 illustrates a so-called side release buckle.

FIG. 2 is a diagram showing an example of how a wearer 200 wears the rugby practice back protector 100 of the present invention according to the first embodiment.
FIG. 2(a) is a front view of the rugby practice back protector 100 applied to the body. In FIG. 2(b), the rugby practice back protector 100 is applied to the body, the length of the left shoulder girdle 130 is adjusted to tighten the left shoulder, and the length of the right shoulder girdle 140 is adjusted to tighten the right shoulder. 3 is a diagram showing a state in which the length of the abdominal band 150 is adjusted and the abdomen is tightened to be worn. FIG. Although the body is not yet tightened in FIG. 2(a), the lengths of these left shoulder girdle 130, right shoulder girdle 140, and abdominal girdle 150 are adjusted to fit the body properly, and the present invention is applied. A back protector 100 for rugby practice is worn.
