本考案は抵抗装置に関し、特に油圧シリンダに取って代わり得るトレーニング マシン用運動抵抗装置に関する。 The present invention relates to a resistance device, and more particularly to a motion resistance device for a training machine that can replace a hydraulic cylinder.
【０００２】[0002]
一般に抵抗する力により運動の目的を達成しているトレーニングマシンは、ほ とんどが油圧シリンダを利用した抵抗装置を使用しており、図１０，図１１で示 す従来例の油圧式ウォーキングマシンの如く、主として、Ｌ字形状を呈したその 縦柱１両側にそれぞれペダル２を枢設して、該両ペダル２1 ，２2 上方にそれぞ れ油圧シリンダ３，４を取付け、該両油圧シリンダ３，４間に管路６を連設する と共に、該両油圧シリンダ３，４両端をそれぞれ縦柱１及びペダル２1 ，２2 末 端に枢接して、そのうちの何れかペダル２1 を踏んだ時に、該ペダル２1 が該縦 柱１の軸ピン１ａを回動中心として、その末端をもたげてそれと対応する油圧シ リンダ３のピストンロッド３ａを押上げ収縮させ（図１１に示す矢印Ａの如く） 、かつ該油圧シリンダ３内のオイル５を該管路６経由で他方の油圧シリンダ４内 に押圧して、該他方の油圧シリンダ４のピストンロッド４ａを矢印Ｂが示す方向 に押出すと共に他方のペダル２2 末端を押下げ、このような動作を反復して競歩 運動の効果を得るようにしているのである。Generally, most training machines that achieve the purpose of exercise by the resistance force use a resistance device that uses a hydraulic cylinder. The conventional hydraulic walking machine shown in FIGS. 10 and 11 is used. As shown in FIG. 1, mainly, pedals 2 are pivotally installed on both sides of the vertical column 1 having an L shape, and hydraulic cylinders 3 and 4 are attached above the pedals 2 1 and 2 2 respectively. A pipe line 6 is continuously provided between the cylinders 3 and 4, and both ends of the hydraulic cylinders 3 and 4 are pivotally connected to the vertical column 1 and the pedals 2 1 and 2 2 end ends, respectively, and one of the pedals 2 1 is connected. when stepping on, as the pivot center of the pedal 2 1 shaft pin 1a of the vertical column 1, shows the piston rod 3a was pushed up shrinkage (Figure 11 of the hydraulic shea cylinder 3 corresponding to it rears its ends arrow A)) and the hydraulic series Presses the oil 5 in Da 3 in pipe line 6 in the other of the hydraulic cylinders 4 via the other pedal 2 2 ends with extruded piston rod 4a of the hydraulic cylinder 4 of the other side in the direction indicated by arrow B By pushing down and repeating such movements, the effect of the racewalking exercise is obtained.
【０００３】 この種従来のトレーニングマシンは油圧シリンダを制動、抵抗作用の部材とし て使っているが、実際に使用して見ると、該油圧シリンダは容易に油漏れ現象を 生じ、そして、一旦、油漏れが生ずると予期する運動効果が得られず、しかも油 圧シリンダは高度の密閉性を要するため高価なもので製造コストが高く、ひいて は補修費もかさむ。In this type of conventional training machine, a hydraulic cylinder is used as a member for braking and resistance action, but when actually used, the hydraulic cylinder easily causes an oil leakage phenomenon, and once, If an oil leak occurs, the expected motion effect cannot be obtained, and since the hydraulic cylinder requires a high degree of tightness, it is expensive and the manufacturing cost is high, and the repair cost is also high.
【０００４】[0004]
上記従来のトレーニングマシン用運動抵抗装置の問題点に鑑み、本考案は、簡 単な構造により油圧シリンダに取って代わって、著しい制動力から所期の運動抵 抗効果が得られると共に、油漏れしない製造組立が容易なトレーニングマシン用 運動抵抗装置を提供することを目的とする。 In view of the above-mentioned problems of the conventional motion resistance device for training machine, the present invention replaces the hydraulic cylinder with a simple structure to obtain a desired motion resistance effect from a remarkable braking force and oil leakage. An object of the present invention is to provide a motion resistance device for a training machine that is easy to manufacture and assemble.

上記目的を達成するため、本考案は、その保持筒と調節スリーブとの間にバレ ルを介装螺接してなる中空内部に軸ロッドを貫挿し、該保持筒の該調節スリーブ と隣接した一端に持受け環を設け、かつ該持受け環周回りに周壁に複数の溝部を 形成した弾性変形可能な中空状摩擦スリーブを取付けて、該軸ロッドの該保持筒 内に挿入した一端が往復移動できるよう該軸ロッドに貫挿された上蓋を該調節ス リーブ上端に螺合被着させ、かつ該上蓋下端が該摩擦スリーブ上端を当接するよ うに構成される。 In order to achieve the above-mentioned object, the present invention inserts a shaft rod into a hollow inside formed by screwing a barrel between the holding cylinder and an adjusting sleeve, and inserts one end of the holding cylinder adjacent to the adjusting sleeve. An elastically deformable hollow friction sleeve with a groove formed on the peripheral wall around the circumference of the holding ring is attached to the one end of the shaft rod inserted into the holding cylinder to reciprocate. An upper lid inserted through the shaft rod is screwed onto the upper end of the adjusting sleeve so that the lower end of the upper lid abuts the upper end of the friction sleeve.
【０００６】 そして、上記摩擦スリーブ周壁に設けられる複数の溝部を、径向きの凹み状リ ング溝又は軸向きの長溝孔で形成するようにしたり、或いは上記保持筒内に弾性 手段を装設したりすると一層好ましい。Further, the plurality of grooves provided on the peripheral wall of the friction sleeve are formed by radial concave ring grooves or axial long slots, or elastic means are provided in the holding cylinder. Is more preferable.
【０００７】[0007]
上記のように構成された、本考案は、その保持筒一端及び軸ロッド一端をそれ ぞれトレーニングマシンの適当な相対位置に固定しているので、運動者が運動抵 抗を比較的大きく設定する時は、その調節スリーブを下向きに回動すると、該上 蓋が連動されて該上蓋下端が該摩擦スリーブ上端縁を押圧し、かつ下方の持受け 環が当接制止作用を務めるので、該摩擦スリーブの長さが縮まり、その溝部内側 面が内向きに迫って軸ロッド周回りを圧迫することになり、したがって、軸ロッ ドと摩擦スリーブとの間に摩擦制動力が生じ、並びに該摩擦スリーブの変形量が 大きくなればなるほど、その生ずる制動力も大きくなり、このように、該調節ス リーブを適当にねじ回すことにより運動抵抗を好むままに調整することができる 。 According to the present invention constructed as described above, one end of the holding cylinder and one end of the shaft rod are fixed to proper relative positions of the training machine, so that the exerciser sets the exercise resistance relatively large. When the adjusting sleeve is turned downward, the upper lid is interlocked, the lower end of the upper lid presses the upper edge of the friction sleeve, and the lower holding ring acts as an abutment stop function. The length of the sleeve is shortened, and the inner surface of the groove is pressed inward to press around the circumference of the shaft rod. Therefore, a friction braking force is generated between the shaft rod and the friction sleeve, and the friction sleeve. The greater the amount of deformation of the, the greater the resulting braking force, and thus, by appropriately screwing the adjusting sleeve, the kinetic resistance can be adjusted as desired.
【０００８】 そして、上記摩擦スリーブ周壁に設けられる複数の溝部を、径向きの凹み状リ ング溝又は軸向きの長溝孔で形成するようにしたり、或いは上記保持筒内に弾性 手段を装設したりすると、上記摩擦スリーブの軸ロッドに対する圧迫度合いがよ り確実に制御でき、かつ、保持筒内で往復移動する軸ロッドの原位置復帰が素早 くなる。The plurality of grooves provided on the peripheral wall of the friction sleeve may be formed by radial concave ring grooves or axial long slots, or elastic means may be provided in the holding cylinder. In this case, the degree of compression of the friction sleeve with respect to the shaft rod can be controlled more reliably, and the shaft rod reciprocating in the holding cylinder can be quickly returned to its original position.

The shaft rod 20 is inserted, and a bellows-shaped ring-shaped recessed portion on the outer peripheral surface thereof is formed in the ring groove 52.

【００１５】 このように形成された、本考案のトレーニングマシン用運動抵抗装置を組立て る時は、図１，図２に示すように、先ず上蓋７０、調節スリーブ６０、摩擦スリ ーブ５０、バレル４０、及び持受け環３０などを軸ロッド２０により貫挿した後 、ねじ２１１により係止環２１を該軸ロッド２０下端に固装し、かつ該係止環２ １下端から該保持筒２０の格納空間１１内部に挿入して、次に該保持筒１０上端 のねじ部１２をバレル４０下端の雌ねじ部４１に緊密に螺締して、該持受け環３ ０を該バレル４０の小径リング部４２に収容し、並びに該保持筒１０、持受け環 ３０、及びバレル４０を一体に連結して、該持ち受け環３０の鍔縁３２の当接制 止作用から該軸ロッド２０下端の係止環２１の移動行程を該保持筒１０内に規制 し、しかる後、該調節スリーブ６０の雌ねじ部６１と該バレル４０上端外周面の 雄ねじ部４３を螺合すると共に、上蓋７０の小径ねじ部７２を該調節スリーブ６ ０の雌ねじ部６１上端に緊密に螺締して、該摩擦スリーブ５０を該圧着部７３と 持受け環３０との間に固定し、全体装置の組立を完了する（図２，図４に示す如 く）。When assembling the exercise resistance device for a training machine of the present invention formed as described above, as shown in FIGS. 1 and 2, first, the upper lid 70, the adjusting sleeve 60, the friction sleeve 50, and the barrel. 40, the holding ring 30, etc., are inserted through the shaft rod 20, and then the locking ring 21 is fixed to the lower end of the shaft rod 20 with a screw 211, and the holding cylinder 20 is fixed from the lower end of the locking ring 21. After being inserted into the storage space 11, the threaded portion 12 at the upper end of the holding cylinder 10 is tightly screwed into the female threaded portion 41 at the lower end of the barrel 40 to attach the holding ring 30 to the small diameter ring portion of the barrel 40. 42, and the holding cylinder 10, the holding ring 30, and the barrel 40 are integrally connected to each other, and the lower end of the shaft rod 20 is locked by the action of the abutment of the flange 32 of the holding ring 30. The movement stroke of the ring 21 is restricted within the holding cylinder 10. After that, the female screw portion 61 of the adjusting sleeve 60 and the male screw portion 43 of the outer peripheral surface of the upper end of the barrel 40 are screwed together, and the small diameter screw portion 72 of the upper lid 70 is tightly fitted to the upper end of the female screw portion 61 of the adjusting sleeve 60. By screwing, the friction sleeve 50 is fixed between the crimp portion 73 and the holding ring 30, and the assembly of the entire apparatus is completed (as shown in FIGS. 2 and 4).
【００１６】 図２は、本考案の無制動状態を示すもので、この際の抵抗装置を運動器材の所 定箇所に取付けて、かつ運動器材を操作して該軸ロッド２０を保持筒１０内で軸 向きの往復運動させると、該摩擦スリーブ５０は押圧されていないので変形がな く、したがって、摩擦スリーブ５０内周面と該軸ロッド２０との間に間隙が存在 するので、この時、運動器材を操作して該軸ロッド２０を往復運動させても何ら かの抵抗もなく、即ち運動者は容易に操作をすることができる。FIG. 2 shows the non-braking state of the present invention, in which the resistance device is attached to a predetermined position of the exercise equipment, and the exercise equipment is operated to hold the shaft rod 20 in the holding cylinder 10. When it is reciprocally moved in the axial direction, the friction sleeve 50 is not pressed and therefore is not deformed. Therefore, since there is a gap between the inner peripheral surface of the friction sleeve 50 and the shaft rod 20, at this time, There is no resistance even if the exercise equipment is operated to reciprocate the axial rod 20, that is, the exerciser can easily perform the operation.
【００１７】 そして、運動者の体力、年齢、及びその適する運動量の違いから、制動力に対 する要求も異なり、もしも比較的大きい運動抵抗を必要とするときは、図３に示 すように、該調節スリーブ６０を締付け側に回動すると、該上蓋と共に該圧着部 ７３が連動されて該摩擦スリーブ５０上端縁を押圧し、かつ下方の持受け環３０ が当接制止作用を提供するので、一旦該摩擦スリーブ５０上端縁が押圧されると 該摩擦スリーブ５０の長さが縮まり、かつその内周面が内向きに迫って該軸ロッ ド２０周回りを圧迫することになり、したがって、軸ロッド２０と摩擦スリーブ ５０との間に摩擦抵抗による制動力が生じ、並びに該摩擦スリーブ５０の変形量 が大きくなればなるほど生ずる制動力も大きくなり、このように、該調節スリー ブ６０を適宜に振り回すことにより運動抵抗を好むままに調節することができる 。Due to the difference in physical strength and age of the exerciser and the suitable amount of exercise, the demands on the braking force are different, and if relatively large exercise resistance is required, as shown in FIG. When the adjusting sleeve 60 is rotated to the tightening side, the crimping portion 73 is interlocked with the upper lid to press the upper end edge of the friction sleeve 50, and the lower holding ring 30 provides a contact stopping action. Once the upper edge of the friction sleeve 50 is pressed, the length of the friction sleeve 50 is shortened, and the inner peripheral surface of the friction sleeve 50 is pressed inward to press the circumference of the shaft rod 20. A braking force due to frictional resistance is generated between the rod 20 and the friction sleeve 50, and as the deformation amount of the friction sleeve 50 increases, the braking force also increases. By appropriately swinging 60, the exercise resistance can be adjusted as desired.
【００１８】 図３に示す如く、運動抵抗、すなわち制動力を調整する時は、該調節スリーブ ６０の下端は該バレル４０上端に嵌着し、かつ調節スリーブ６０の回動に随って その円弧面状の凸起６４１は瞬時縦溝４４に陥落して、該バレル４０と該調節ス リーブ６０が相対しているうちは、該弾性片６４の作用から該円弧面状の凸起６ ４１が踊動して“ガタッ，ガタッ…”と音を立て、更に該調節スリーブ６０下端 を該目盛り４５に合わせると制動力の大きさが分かり、また該目盛り４５に下端 両端に“＋”，“−”の指示標記４６を付けて、制動力の増加又は現象かを表示 させるようにしてもよい（図１，図４に示すように）。As shown in FIG. 3, when adjusting the kinetic resistance, that is, the braking force, the lower end of the adjusting sleeve 60 is fitted to the upper end of the barrel 40, and the circular arc of the adjusting sleeve 60 is rotated according to the rotation of the adjusting sleeve 60. The planar ridge 641 falls into the instantaneous vertical groove 44, and while the barrel 40 and the adjusting sleeve 60 face each other, the arc-shaped ridge 641 is generated by the action of the elastic piece 64. When dancing, making a rattling sound, and adjusting the lower end of the adjusting sleeve 60 with the scale 45, the magnitude of the braking force can be known, and the lower end of the scale 45 has "+", "-" at both ends. The indication mark 46 of "" may be attached to indicate whether the braking force is increased or a phenomenon (as shown in FIGS. 1 and 4).
【００１９】 図５，図６に示すのは、本考案におけるもう一つの実施例で、図示のように、 その摩擦スリーブ５０’周壁に挿通孔５１’に至る複数の軸向き長溝孔５２’を ほぼ等間隔に周設して、図７に示すように、該調節スリーブ６０を回動して制動 力を増強する時に、該摩擦スリーブ５０が押圧されて、その長溝孔５２’を周設 した中段部位が湾曲変形して、内側に迫り出した部分が該軸ロッド２０周回りを 圧迫して制動力を生じ、これにより上記実施例と同様に運動抵抗の調整効果が得 られる。FIG. 5 and FIG. 6 show another embodiment of the present invention. As shown in the drawing, the friction sleeve 50 ′ has a plurality of axial slots 52 ′ extending to the insertion hole 51 ′ on the peripheral wall thereof. As shown in FIG. 7, when the adjusting sleeve 60 is rotated to increase the braking force, the friction sleeve 50 is pressed and the elongated slot 52 'is provided at substantially equal intervals. The middle part is curved and deformed, and the part that protrudes inward presses around the circumference of the shaft rod 20 to generate a braking force, and as a result, the same effect of adjusting the motion resistance can be obtained.
【００２０】 これら実施例の操作態様から見ると、運動操作をしている時は、該軸ロッド２ ０の往復伸縮作動からの運動の目的を達成するのであり、もしも、伸出した軸ロ ッド２０をより速く原位置に復帰させたい場合は、図８に示す如く、該保持筒１ ０内部に突張りばね８０のような弾性部材を設けてもよく、該突張りばね８０を 該軸ロッド２０周辺に取付けると共に、その両端をそれぞれ持受け環３０の鍔縁 ３２及び係止環２１に当接させて、該軸ロッド２０が引張り出されると該突張り ばね８０が弾性変形し、該軸ロッド２０の引張る力を除去すると、該突張りばね ８０が弾性回復して、該軸ロッド２０を原位置に追いやるようにすると、運動操 作をより簡単敏捷に行なうことができる。As seen from the operation modes of these examples, when the motion operation is performed, the purpose of the motion from the reciprocating expansion / contraction operation of the shaft rod 20 is achieved. If it is desired to return the cord 20 to the original position more quickly, an elastic member such as a tension spring 80 may be provided inside the holding cylinder 10 as shown in FIG. The tension spring 80 is elastically deformed when the shaft rod 20 is pulled out while being attached to the periphery of the rod 20 and contacting both ends thereof with the brim 32 of the holding ring 30 and the locking ring 21, respectively. When the pulling force of the shaft rod 20 is removed, the tension spring 80 elastically recovers to drive the shaft rod 20 to the original position, so that the maneuvering operation can be performed more easily and agilely.
【００２１】 無論、図９に示すように、もしも操作態様が上記方向と逆の場合、すなわち、 運動操作の出力が該軸ロッド２０を収縮させるものであれば、収縮した該軸ロッ ド２０を素早く原位置に復帰させたいときは、該突張りばね８０’両端をそれぞ れ係止環２１底端面と保持筒１０内底面に当接させるよう該格納空間１１に取付 ければよく、収縮した軸ロッド２０を素早く伸出復帰させることができる。Of course, as shown in FIG. 9, if the operation mode is opposite to the above direction, that is, if the output of the motion operation causes the axial rod 20 to contract, the contracted axial rod 20 is In order to quickly return to the original position, the tension springs 80 ′ may be attached to the storage space 11 so that both ends of the tension spring 80 ′ come into contact with the bottom end surface of the locking ring 21 and the inner bottom surface of the holding cylinder 10, respectively, and the contraction occurs. The axial rod 20 can be quickly extended and returned.

上記のように構成された、本考案は、運動者の欲する運動量に応じて運動抵抗 を調整するときは、その調節スリーブを回転すると、その摩擦スリーブの該軸ロ ッド周回りに対する圧迫力を加減することができるので、このように、該調節ス リーブを適宜にねじ捩じ回すことにより運動抵抗を好む侭に調整することができ る。したがって、簡単な構造から油圧シリンダに取って代わって、所望の運動抵 抗が得られると共に、油漏れしない上に製造・組立が容易であるメリットがある 。 According to the present invention configured as described above, when the exercise resistance is adjusted according to the exercise amount desired by the exerciser, when the adjustment sleeve is rotated, the pressing force of the friction sleeve around the shaft rod is applied. Since it can be adjusted, the exercise resistance can be adjusted to the preferred side by appropriately screwing the adjusting sleeve. Therefore, the hydraulic cylinder is replaced with a simple structure to obtain a desired motion resistance, and there is an advantage that oil leakage does not occur and manufacturing / assembly is easy.
