本考案は運動鍛練装置に関し、特に筋力の強

ど多機能をもつ運動鍛練装置に関する。[Detailed Description of the Invention] The present invention relates to an exercise training device, and particularly to an exercise training device that has multiple functions such as strengthening muscle strength, training jumping ability, developing a sense of balance, and playing games.
従来跳躍力の鍛練には第１図及び第２図に示す

間に所定の角間隔を保つて放射状に延長する多数
の引張ばね４が装架されている。 Conventionally, jumping devices such as those shown in FIGS. 1 and 2 have been used to train jumping ability. Reference numeral 1 denotes an annular frame made of iron pipe, which is held substantially horizontally at a predetermined height from the floor by, for example, four legs 2. A circular sheet 3 made of, for example, woven fabric and having a diameter smaller than the inner diameter of the frame 1 is disposed in the inner circle of the frame 1, and a number of circular sheets 3 extending radially with a predetermined angular interval maintained between the periphery and the frame 1 are arranged. A tension spring 4 is installed.

つてばね４を伸張させ、その後ばね４が短縮した
ときシート３を介してプレーヤに対して上方への
反発力を与えることにより、プレーヤの跳躍を助
けるようになされている。 In the jumping apparatus shown in FIGS. 1 and 2, if the player jumps up and down while riding on the seat 3, when the player descends onto the seat 3, the spring 4 is expanded by its gravity, and then the spring 4 is When shortened, an upward repulsive force is applied to the player via the seat 3 to help the player jump.
しかるにこの従来の構成の跳躍装置によれば、
シート３の周囲に多数のばね４が所定の間隔を保
つて配置されているので、プレーヤが跳躍中に誤
つてシート３から外側に跳び出したときにばね４

プレーヤが床からシート３上に乗る際又は降りる
際にはばね４の部分を踏まないように気をつけな
ければならない。 However, according to this conventionally configured jumping device,
A large number of springs 4 are arranged around the seat 3 at predetermined intervals, so that if the player accidentally jumps outward from the seat 3 while jumping, the springs 4
There is a risk of falling and getting injured. Furthermore, when the player gets on or off the seat 3 from the floor, he or she must be careful not to step on the spring 4.

レーヤが上手に跳躍するためには、一定の慣れが
必要で、実際上年少者や、身体に障害がある人な
どは使いこなせない不都合がある。 Furthermore, according to this conventional jumping device, when the player descends onto the seat 3 and the seat 3 extends downward, the tensile force applied by the spring 4 is considered to be in the plane direction of the seat 3. It is considered that a force equal to the vector sum of the tensile forces applied to the sheet 3 acts on the sheet 3. Therefore, as shown in FIG. 3A, if the player descends to the middle of the seat 3 while putting his weight evenly on both feet, the seat 3 will be concave at approximately the same angle with the feet 5 at the center, so the player will have little impact. A vertical repulsive force is applied. This is because the horizontal force components applied to the player from the seat 3 cancel each other vectorwise. However, in reality, this horizontal force component acts as a force that tightens the area around the foot 5, causing the player to feel uncomfortable. Furthermore, if the player descends to a position away from the center of the seat 3 as shown in FIG. becomes unbalanced and the discomfort in leg 5 changes. Therefore, in order for a player to jump well, a certain level of familiarity is required, and in practice this is inconvenient for young people and people with physical disabilities to be unable to use it effectively.
これに加えてこの種の跳躍装置においては、プ
レーヤが降下したときプレーヤが乗る部分の沈み
量を大きくできれば、その分プレーヤの運動量が
大きくなるので跳躍装置としての機能を一段と拡
大できると考えられる。 In addition, in this type of jumping device, if the amount of sinking of the part on which the player rides when the player descends can be increased, the momentum of the player will increase accordingly, and it is thought that the function as a jumping device can be further expanded.
本考案は以上の点を考慮してなされたもので、
けがのおそれや、取扱いの煩雑さを格段的に軽減
し得ると共に、単に跳躍運動のみならず筋力の強

多くの機能を実現し得る運動鍛練装置を提案する
ものである。 This idea was created taking the above points into consideration.
An exercise training device that can significantly reduce the risk of injury and the complexity of handling, and can also achieve many functions such as strengthening muscle strength, developing a sense of balance, and playing various games in addition to simply jumping exercises. This is what we propose.
以下図面について本考案の一実施例を詳述する
に、第４図において運動鍛練装置１１は円形の下
側板１２及び上側板１３間に複数例えば５個の押
しばね１４を装着し、その周囲をシート状カバー
１５によつて覆つた構成を有し、下側板１２の下
面に取付けられた多数例えば11個の比較的高さの
低い足１６によつて床にほぼ水平に置かれる。 An embodiment of the present invention will be described below in detail with reference to the drawings. In FIG. 4, the exercise training device 11 is equipped with a plurality of, for example, five, pressure springs 14 between a circular lower plate 12 and an upper plate 13. It has a structure covered by a sheet-like cover 15, and is placed approximately horizontally on the floor by means of a number of, for example, eleven, relatively low-height feet 16 attached to the lower surface of the lower side plate 12.
ここで押しばね１４はコイルスプリングでな

外形形状を有する。すなわち押しばね１４は第５
図Ａに示す如く根元から上方に行くに従つて直径

４は例えばＵボルトでなる取付け金具（図示せ
ず）によつて下端部１４Ａを下側板１２の上面に
固着されかつ上端部１４Ｂを上側板１３の下面に
固着されている。 The push spring 14 is a coil spring, and has an outer shape whose diameter gradually changes in the axial direction. That is, the push spring 14 is the fifth
As shown in Figure A, it has a truncated conical shape whose diameter decreases as it goes upward from the base. Each push spring 1
4 has a lower end 14A fixed to the upper surface of the lower plate 12 and an upper end 14B fixed to the lower surface of the upper plate 13 by means of mounting fittings (not shown) made of, for example, U-bolts.
かくして押しばね１４は上側板１３に荷重がか
かつて第５図Ｂに示すように圧縮されたときコイ

コイルスプリングは直径の大きい部分が小さい部
分より弾発力が弱いので、円錐台形状をもつ押し
ばね１４は下部から折り畳まれて行くことにな
る。 Thus, when the push spring 14 is compressed as shown in FIG. 5B when a load is applied to the upper plate 13, the lower part 14C of the coil spring gradually comes into contact with the inner position of the lower end 14A on the lower plate 12. When it is most compressed, it is folded to a thickness of the diameter of the wire forming a coil spring. Incidentally, since the larger diameter portion of the coil spring has a weaker elastic force than the smaller diameter portion, the truncated conical push spring 14 is folded from the bottom.

５Ｂの下縁部が下側板１２の下面に接着される。
かくしてカバー１５は上下端面を閉塞した扁平円
筒状となされ、その内部に上側板１３、押しばね
１４、下側板１２を一体に組立ててなる弾性体を
覆うように収納する。 The cover 15 is a circular cap-shaped upper sheet portion 15A that covers the upper surface or side surface of the protective plate 17 made of the upper plate 13 and a cushioning material attached to the upper surface thereof.
, a lower sheet part 15B that covers the lower surface or side surface of the lower plate 12, and the upper plate 13 and the lower plate 12.
and an intermediate mesh part 15C that covers the intermediate part of
The upper edge of the intermediate mesh portion 15C is the upper sheet portion 1
The lower edge of the intermediate mesh portion 15C is connected to the lower edge of the lower sheet portion 15B by sewing, for example, and the lower edge of the intermediate mesh portion 15C is connected to the upper edge of the lower sheet portion 15B.
The lower edge of 5B is adhered to the lower surface of the lower plate 12.
Thus, the cover 15 has a flat cylindrical shape with its upper and lower end faces closed, and is housed therein so as to cover the elastic body formed by integrally assembling the upper plate 13, the push spring 14, and the lower plate 12.
かくして上側板１３及び保護板１７上に荷重が
かかつて押しばね１４が圧縮されたときカバー１

中間メツシユ部１５Ｃを通じて外部から空気がほ
とんど抵抗なく吸入され、従つて上側板１３は押
しばね１４と荷重との関係の変化に応じて抵抗な
く上下動できるようになされている。 Thus, when a load is applied to the upper plate 13 and the protection plate 17 and the pressure spring 14 is compressed, the cover 1
Air inside the cover 15 is discharged to the outside through the intermediate mesh portion 15C with almost no resistance, and when the push spring 14 is expanded from this state, air is sucked into the inside of the cover 15 from the outside through the intermediate mesh portion 15C with almost no resistance. Thus, the upper plate 13 can be moved up and down without resistance in response to changes in the relationship between the push spring 14 and the load.
この上下動の間において押しばね１４が圧縮さ

因みに実験によれば、カバー１５がない状態で上
側板１３に人が立つと横方向に不安定に揺動する
が、カバー１５をつけたことによりこの横方向の
揺動を抑えることができた。 When the push spring 14 is compressed during this vertical movement, the cover 15 slackens, but since the middle portion is in the form of a net, it hardly protrudes outside, and therefore there is no risk of it becoming unusable. Incidentally, if the entire cover 15 is made of a sheet, the internal pressure of the sheet 15 increases during compression, causing the cover 15 to protrude to the outside, but with the configuration shown in FIG. 4, there is no risk of this. In fact, the cover 15 functions as a supporting member for the plurality of push springs 14 which stand upright as a whole, and therefore the vertical movement of the upper plate 13 becomes stable.
Incidentally, according to experiments, when a person stands on the upper board 13 without the cover 15, it swings unstably in the lateral direction, but by attaching the cover 15, this lateral swing can be suppressed. .

れる。 A soundproof plate 21 made of a soft cushioning material, such as felt, is inserted into a portion of each push spring 14 near the lower plate 12 so as to extend along the lower plate 12. As shown in FIG. 6, the soundproof plate 21 has a configuration in which a cut 21A is made in the radial direction in a part of a circular felt. The rising wire portion 14D from which the wire portion at the base end has risen is passed through the cut 21A of the soundproof plate 2.
A soundproof plate 21 is inserted into the base end portion of a push spring 14 made of a coil spring so as to extend upwardly. The soundproof board 21 is fixed to the upper surface of the lower board 12 by screws 22 extending through the center thereof.
かくして押しばね１４が第５図Ｂについて上述

合吸盤２４は盃を伏せたと同様の形状をもつゴム
材で作られている。 The legs 16 are formed from a rubber material into the shape of an inverted truncated cone and are fixed to the lower surface of the lower plate 12 with screws 23, and have suction cups 24 glued to their tips. Here, the suction cup 24 prevents the exercise training device 11 as a whole from floating off the floor when the push spring 14 repeatedly compresses and expands, especially due to the reaction of the member that moves upward during the expansion operation. The upper plate 13 is designed to be able to adsorb to the floor surface for a period of time (for example, about 1 second) from the time when the push spring 14 is compressed by the load applied to it until the push spring 14 completes its extension operation by overcoming this load. being done. In this embodiment, the suction cup 24 is made of a rubber material and has a shape similar to that of a cup turned upside down.
以上の構成の運動鍛練装置１１において、これ

て跳躍運動を繰返せば良い。このとき押しばね１
４はプレーヤからの荷重に応じた深さに圧縮さ
れ、弾発力が荷重に克つようになると伸長動作し
てプレーヤに跳躍力を与える。 When using the exercise training device 11 having the above configuration as a jumping device, the player only has to step on the protection plate 17 of the upper plate 13 from above the cover 15 and repeat the jumping motion. At this time, push spring 1
4 is compressed to a depth corresponding to the load from the player, and when the elastic force overcomes the load, it expands to provide a jumping force to the player.
かくしてプレーヤは跳躍運動を続けることがで
きるが、プレーヤがどの位置に降下しても上側板
１３を介して複数の押しばね１４を圧縮させるこ

みにプレーヤは常に保護板１７上に降下すること
ができるので、降下した位置によつて保護板１７
の傾斜角度は変つても足に局部的な力が加わるこ
とはない。 In this way, the player can continue his jumping motion, but no matter where the player descends, the plurality of compression springs 14 can be compressed via the upper plate 13, so that the player's movement as in the case of FIG. There is no risk of giving unnecessary pressure to the feet. Incidentally, since the player can always descend onto the protective plate 17, the position of the protective plate 17 depends on the position from which the player descends.
Even if the inclination angle of the foot changes, no local force is applied to the foot.
上述においては運動鍛練装置１１を跳躍運動に

伸長動作は上側板１３、保護板１７、カバー１５
によつて制限されているのでプレーヤの腕に不測
かつ無理な力が加えられるおそれはない。 In the above, a case has been described in which the exercise training device 11 is used for jumping exercise, but if the player does not step on the protective plate 17 but pushes it down with his hand,
It can be used as a training tool for training the muscle strength of the arm, and even in this case, it does not receive dangerous repulsive force from the protection plate 17 or the push spring 14. Incidentally, the extension operation of the push spring 14 is performed by the upper plate 13, the protection plate 17, and the cover 15.
, so there is no risk of unexpected and unreasonable force being applied to the player's arm.
またプレーヤが保護板１７上に乗つた状態で立
つ位置を変えれば保護板１７の傾斜が変化するの
で、バランス感覚を養成するための訓練に使用で
きる。 Furthermore, if the player changes the standing position while riding on the protective plate 17, the slope of the protective plate 17 changes, so that it can be used for training to develop a sense of balance.
さらに全体としてカバー１５によつて単純な形
状にまとめられているので、複数の運動鍛練装置
１１を任意の形に配列し、その上を跳躍しながら
渡り歩くようにすれば、遊技をかねて跳躍力、バ
ランス感覚などの鍛練を行うことができる。 Furthermore, since the overall shape is summarized by the cover 15, by arranging a plurality of exercise training devices 11 in an arbitrary shape and walking over them while jumping, you can increase jumping power and You can train your sense of balance, etc.

発生する騒音は防音板２１によつて有効に軽減さ
れる。 Particularly, the maximum stroke when the push spring 14 is compressed is the maximum stroke under the push spring 14 because the push spring 14 is formed into a truncated cone shape whose diameter changes as it goes in the axial direction. It is possible to take a large stroke value up to the maximum that allows the wire rod to be folded to the thickness of one wire rod that is in contact with the side plate 12. Therefore, the vertical momentum of the player riding on the upper plate 13 can be expanded to a magnitude corresponding to the height of the push spring 14. In addition, when the player jumps with the maximum stroke, the push spring 14 is folded onto the lower plate 12, and the noise generated at this time is effectively reduced by the soundproof plate 21.
なお、上述においては全体の形状を円筒形にし
た場合について述べたが、これに限らず長方形、
楕円形など種々変形し得る。 In addition, in the above, the case where the overall shape is cylindrical is described, but this is not limited to rectangular,
It can be modified into various shapes such as an ellipse.

る。 As described above, according to the present invention, the push spring is provided inside the cover, the overall shape is compact, and there is no risk of applying dangerous force to the player.
Therefore, it is possible to obtain an exercise training device that has multiple functions for many uses. Incidentally, games for young children and training for people with physical disabilities can be carried out without any danger. Accordingly, in particular, according to the present invention, by configuring the push spring with a truncated cone-shaped coil spring and providing a soundproof plate, the maximum stroke of the upper plate can be maximized without causing noise. It can be made bigger.
