Hereinafter, one embodiment of a training machine for abdominal muscle training of the present invention will be described with reference to the drawings.
1 and 2 show an embodiment of a training machine for abdominal muscle training of the present invention. In the figure, reference numeral 1 denotes a support made of an angle such as iron. A seat portion 2 on which a user sits is fixed to the support body 1 and is integrated with a pivot 10 so as to rotate relative to the seat portion 2, and an armrest portion bent and formed in a substantially U-shape. 3 is provided. The armrest portion 3 has a pair of left and right elbow rests 5 and 5 on which a user's arm is placed, and grip portions 6 and 6 standing at both free ends of the armrest portions 5 and 5 are used as a base portion. A backrest portion 4 having a cushioning property for abutting the back of the person is provided.
The base portion 7 of the seat portion 2 has a protruding portion 8 protruding forward, and a cylindrical front pad 9 is provided on the protruding portion 8. When the user sits on the seat 2 and pivots the armrest 3 to the left and right with the front pad 9 sandwiched between the crotch of both legs, the front pad 9 prevents the lower body from rotating, and the upper body is effectively rotated. Dynamic movement is allowed. By adopting the front pad 9 that is filled with a cushion material or the like inside the skin formed in a cylindrical shape with a skin or the like, it is possible to relieve the user's crotch feeling during training.
In the figure, 13 is a bearing that supports the pivot 10 of the armrest portion 3, 14 is a stopper made of, for example, urethane rubber, and 16 is a footrest. The pivoting of the armrest 3 is normally set at a swing angle of about 96 °, and the stopper 14 is provided at the end position of the pivoting operation of the armrest 3, and the armrest 3 is brought into contact and stopped rotating. It absorbs the impact.

本発明の腹筋鍛錬用トレーニングマシンは、肘掛部3を回動可能に枢支する回転軸10の軸端部12に負荷装置11が取付けられ、この負荷装置11は前記座部2の基部7と固定され肘掛部3の回動時に使用者に負荷を付与することができるように構成されている。   In the training machine for abdominal muscle training of the present invention, a load device 11 is attached to the shaft end portion 12 of the rotary shaft 10 that pivotally supports the armrest portion 3, and the load device 11 is connected to the base portion 7 of the seat portion 2. It is configured so that a load can be applied to the user when the armrest 3 is fixed.

本発明において用いる付加装置11は、図3に示すように既知のロータリアクチュエータの構造の一部を採用したシリンダ装置である。負荷装置11は筺体20に回転自在に支持された出力軸21Aを有するピニオン21を備え、当該ピニオン21には連結ロッド23と一体のラック22が噛合している。前記出力軸21Aは前記枢軸10の軸端部12と図示しないカップリング等を介して接続されている。連結ロッド23の左右両端には、一対のピストン24a、24bが一体に設けられており、各ピストン24a、24bは、それぞれ左右に配置された一対のシリンダ25a、25b内に摺動自在に収容され、矢印C、D方向に往復動自在に構成されている。出力軸21Aが時計回り(矢印E方向)に強制回動されると連結ロッド23は矢印C方向に移動し、また出力軸21Aが反時計回り(矢印F方向)に回動すると、連結ロッド23は矢印D方向に移動し、この移動動作が使用者への負荷抵抗として作用する。負荷装置11は支持体1の基部7下に取付部20aを介して固定され、これにより付加装置11が器具全体にコンパクトに取付け設置でき、器具の大型化を回避し得ることとなる。   The additional device 11 used in the present invention is a cylinder device adopting a part of a known rotary actuator structure as shown in FIG. The load device 11 includes a pinion 21 having an output shaft 21 </ b> A that is rotatably supported by the housing 20, and a rack 22 that is integral with a connecting rod 23 meshes with the pinion 21. The output shaft 21A is connected to the shaft end 12 of the pivot shaft 10 via a coupling (not shown). A pair of pistons 24a and 24b are integrally provided at both left and right ends of the connecting rod 23, and each piston 24a and 24b is slidably accommodated in a pair of cylinders 25a and 25b disposed on the left and right, respectively. , And can be reciprocated in the directions of arrows C and D. When the output shaft 21A is forcibly rotated clockwise (arrow E direction), the connecting rod 23 moves in the direction of arrow C. When the output shaft 21A is rotated counterclockwise (arrow F direction), the connecting rod 23 is moved. Moves in the direction of arrow D, and this movement acts as a load resistance to the user. The load device 11 is fixed under the base portion 7 of the support 1 via the mounting portion 20a, whereby the additional device 11 can be compactly mounted and installed on the entire device, and an increase in size of the device can be avoided.

一対のシリンダ25a、25bのそれぞれの一端側は前記筺体20に密に嵌合する一方、他端側は端面封止ブロック26a、26bによって封止され、各ピストン24a、24bと端面封止ブロック26a、26bとの間に圧力室27a、27bがそれぞれ区画形成されてピストン組立体が構成されている。ピストン組立体は複数のボルト31、31によってピストン軸方向に押圧固着されて負荷装置11を堅固に構成している。各端面封止ブロック26a、26bには各圧力室27a、27bに圧力媒体を供給、排出するための給排ポート28a、28bが設けられ、各給排ポート28a、28bは圧力媒体ホース29を介して接続され、圧力媒体32を圧力室27aと圧力室27bとの間で移動させる閉ループ循環系が形成されており各給排ポート28a、28b側には圧力媒体の流量を制御して圧力調整を行う制御手段としてのフローコントロールバルブ30a、30bが設けられている。給排ポート28a側のフローコントロールバルブ30aは、ピニオン21が反時計回りの方向(矢印F方向)に回動する時の圧力媒体32の流量を制御してピストンにかかる圧力を調整し、図4(B)に示す状態から圧力媒体32が矢印G方向に移動するときの抵抗の制御を司る。また給排ポート28b側のフローコントロールバルブ30bは、ピニオン21が時計回りの方向(矢印E方向)に回動する時の圧力媒体32の流量を制御してピストンにかかる圧力を調整し、図4(A)に示す状態から圧力媒体32が矢印H方向に移動するときの抵抗の制御を司る。フローコントロールバルブ30a、30bによる圧力を、例えば5〜105Nの圧力幅でリニアーに調整できるように構成することで、使用者に適宜の回動負荷を与えることができ、使用者の体力に合わせた設定が可能となる。図示した例ではフローコントロールバルブを一対設けた場合を示したが、往復の圧力を調整できればフローコントロールバルブの数は限定されず、適宜数を設けることができる。尚、フローコントロールバルブ30a、30bは、ピニオン21が矢印E方向に回動した時も、F方向に回動したときも同じ圧力が加わるようにバランス良く調節することが好ましい。   One end side of each of the pair of cylinders 25a and 25b is closely fitted to the housing 20, while the other end side is sealed by end face sealing blocks 26a and 26b. The pistons 24a and 24b and the end face sealing block 26a are sealed. , 26b, pressure chambers 27a, 27b are respectively defined and a piston assembly is configured. The piston assembly is firmly fixed in the axial direction of the piston by a plurality of bolts 31, 31 to firmly constitute the load device 11. Each end face sealing block 26 a, 26 b is provided with supply / discharge ports 28 a, 28 b for supplying and discharging the pressure medium to and from each pressure chamber 27 a, 27 b, and each supply / discharge port 28 a, 28 b is connected via a pressure medium hose 29. Are connected, and a closed loop circulation system for moving the pressure medium 32 between the pressure chamber 27a and the pressure chamber 27b is formed. The pressure adjustment is performed by controlling the flow rate of the pressure medium on each of the supply / discharge ports 28a and 28b. Flow control valves 30a and 30b are provided as control means to perform. The flow control valve 30a on the supply / discharge port 28a side adjusts the pressure applied to the piston by controlling the flow rate of the pressure medium 32 when the pinion 21 rotates counterclockwise (arrow F direction). It controls the resistance when the pressure medium 32 moves in the arrow G direction from the state shown in FIG. The flow control valve 30b on the supply / exhaust port 28b side controls the flow rate of the pressure medium 32 when the pinion 21 rotates in the clockwise direction (arrow E direction) to adjust the pressure applied to the piston. It controls the resistance when the pressure medium 32 moves in the arrow H direction from the state shown in FIG. By configuring so that the pressure by the flow control valves 30a and 30b can be adjusted linearly with a pressure range of, for example, 5 to 105N, an appropriate rotational load can be given to the user, and the physical strength of the user can be adjusted. Setting is possible. In the illustrated example, a pair of flow control valves is shown. However, the number of flow control valves is not limited as long as the reciprocating pressure can be adjusted, and an appropriate number can be provided. The flow control valves 30a and 30b are preferably adjusted in a well-balanced manner so that the same pressure is applied when the pinion 21 rotates in the direction of arrow E and when it rotates in the F direction.

次に、本発明の腹筋鍛錬用トレーニングマシンを用いて使用者が腹筋(腹斜筋)の鍛錬を行う操作について、図5(A)、(B)により説明する。
使用者は本発明のトレーニングマシンの座部2に座るとともに股でフロントパット9を挟み、肘掛部3の肘当部5、5に両腕を載置して握り部6、6を両手でしっかり握る。この時、肘掛部3を回動させて使用者が上半身を捻る動作をし易いように、背中を背当て4に姿勢よく付ける。ついで使用者は、例えばまず図5(A)に示すように上半身を右方向に捻るように肘掛部3を時計回り方向(矢印A方向)に回動させるとピニオン21が矢印E方向に回動し、負荷装置11は例えば図3に示すイニシャルの状態(或いは図4(A)の状態)から、図4(B)に示す状態となるように、一方の圧力室27a方向に圧力媒体32が移動し、この圧力媒体の移動が使用者への負荷として作用する。圧力媒体がフローコントロールバルブ30b側からフローコントロールバルブ30a側へ移動する時、一方のフローコントロールバルブ30bが圧力調節に寄与し、他方のフローコントロールバルブ30aは開放状態となっている。次いで図5(B)に示すように使用者が上半身を逆方向に捻るようにして肘掛部3を反時計回り方向(矢印B方向)に回動させると、ピニオン21が矢印F方向に回動し、負荷装置11は図4(B)の状態から図4(A)に示す状態となるように、圧力室27b方向に圧力媒体32が移動し圧力媒体の移動が使用者への負荷として作用する。このとき、フローコントロールバルブ30aが圧力調整に寄与し、フローコントロールバルブ30bは開放状態となっている。肘掛部3の回動によって負荷装置11には肘掛部3の回動運動を妨げようとする負荷トルクが生じるため、使用者は肘掛部3を負荷に抗して回動させることとなり、使用者が肘掛部3を左右交互に回動させる操作を所定回数繰り返すことにより体幹部の左右の腹斜筋をバランス良く鍛えることができる。
Next, an operation in which the user trains the abdominal muscles (abdominal oblique muscles) using the training machine for abdominal muscle training of the present invention will be described with reference to FIGS.
The user sits on the seat portion 2 of the training machine of the present invention, sandwiches the front pad 9 with his crotch, places both arms on the armrest portions 5 and 5 of the armrest portion 3, and firmly holds the grip portions 6 and 6 with both hands. Hold. At this time, the back is put on the backrest 4 with a good posture so that the user can easily turn the upper body by rotating the armrest 3. Next, for example, as shown in FIG. 5A, the user first rotates the armrest 3 in the clockwise direction (arrow A direction) so as to twist the upper body in the right direction, and the pinion 21 rotates in the arrow E direction. For example, the load device 11 has the pressure medium 32 in the direction of the one pressure chamber 27a so that the initial state shown in FIG. 3 (or the state shown in FIG. 4A) is changed to the state shown in FIG. 4B. The pressure medium moves and acts as a load on the user. When the pressure medium moves from the flow control valve 30b side to the flow control valve 30a side, one flow control valve 30b contributes to pressure adjustment, and the other flow control valve 30a is in an open state. Next, as shown in FIG. 5B, when the user turns the armrest 3 in the counterclockwise direction (arrow B direction) by twisting the upper body in the opposite direction, the pinion 21 rotates in the arrow F direction. Then, the load device 11 moves from the state of FIG. 4B to the state shown in FIG. 4A, and the pressure medium 32 moves in the direction of the pressure chamber 27b, and the movement of the pressure medium acts as a load on the user. To do. At this time, the flow control valve 30a contributes to pressure adjustment, and the flow control valve 30b is in an open state. Since the load device 11 generates load torque that hinders the rotational movement of the armrest portion 3 due to the rotation of the armrest portion 3, the user rotates the armrest portion 3 against the load. However, the left and right abdominal oblique muscles of the trunk can be trained in a well-balanced manner by repeating the operation of rotating the armrests 3 alternately left and right a predetermined number of times.

上記実施例は、支持体1に座部2を固定し、肘掛部3を座部2に対して回転可能に構成した場合を示したが、本発明の腹筋鍛錬用トレーニングマシンは、肘掛部3を支持体1に固定し、肘掛部3に対して座部2を回転可能に構成し、座部2の回転軸に負加装置11を設け、座部2を回動させることで座部2に負荷装置11からの負荷を加えるように構成しても良い。いずれにしても枢軸に負荷手段を設けるため器具をコンパクトに構成することができ、すこぶる使い勝手が良いものとなる。   Although the said Example showed the case where the seat part 2 was fixed to the support body 1 and the armrest part 3 was comprised rotatably with respect to the seat part 2, the training machine for abdominal muscle training of this invention is the armrest part 3. Is fixed to the support 1, the seat 2 is configured to be rotatable with respect to the armrest 3, a negative device 11 is provided on the rotating shaft of the seat 2, and the seat 2 is rotated by rotating the seat 2. Alternatively, a load from the load device 11 may be applied. In any case, since the load means is provided on the pivot, the instrument can be made compact, and the usability is extremely good.
