  By the way, in contrast to the conventional focus on strengthening the “surface muscle (outer muscle)”, the conventional muscle strength improvement has recently played a role of supporting the body (located in the back). "Inner muscle)" is spotlighted. And when the “deep muscles” are weakened and inactivated, the supporting force declines and the posture changes, and accordingly, symptoms such as low back pain, knee pain, foot pain, fifty shoulders, and stiff shoulders are likely to occur in the elderly, etc. I know that. Here, the “deep muscle” is a muscle that has a role to fix and protect the joint and is important for the movement of the rotating system. In order to activate this “deep muscle”, it has been found that it is important to consciously move the hip joint rhythmically (for example, “weak, small, slowly”). However, the conventional training device applies a load to the surface muscle, for example, by performing a stretching operation of the foot, so that there is an effect of training the surface muscle, but when the foot is bent and stretched, the pronator muscle (foot) The hip muscles around the hip joint) cannot be twisted, and the effect of training the deep muscles was poor.

  And although the said conventional training instrument makes a leg extend / contract with respect to the leg bending / extension tool with a load, it applies a load unilaterally. Therefore, if it is possible to perform the twisting motion of the foot naturally without difficulty, it will be an ideal training.

  In view of the above, an object of the present invention is to effectively perform the exercise of twisting the pronation muscle of the foot (leg) (peripheral muscle at the back of the base of the foot) and to apply as little load as possible to the foot. It is an object of the present invention to provide a training device that can naturally train inner muscles without difficulty and is suitable for functional recovery training for disabled and elderly people.

To this end, the training device of the present invention, the trainee is on his back on the bench arranged obliquely to the base frame, the leg bending tool to the bench downward and upward, can slide In a training device that is arranged on the base frame and applies a load to the foot, the leg bending device extends and contracts by bringing the foot into contact with the bench side surface of the leg bending device. the attached through a shaft to the plane of the bench-side, with the trainee has intensive foot is brought into contact with the rotating plate by the leg bending tool becomes his back on the bench, the rotating plate The rotating plate is rotated by twisting inward or outward of the foot while performing a stretching operation of the foot in contact with the foot .

  In this invention, when the rotating plate attached to the leg flexion / extension device is rotated inwardly or outwardly with the foot, the pronation muscle of the foot (leg) (the muscle around the hip joint at the back of the base of the foot) is twisted. You can exercise and train your hip muscles. By changing the size of the barbell, the array, etc., the load applied to the leg flexion / extension device can be increased. In order to reduce the load as much as possible, only the rotating plate may be moved without using a barbell or an array.

The present invention, to allow smooth rotation of the rotating plate, said rotating plate, said attached via a rotating aid between the legs bending tool to rotate the rotary plate by the training's foot operation It can be set as the structure which assists . Examples of the rotation assist tool include a bearing, a screw, and a lubricant.

As this invention, the said rotation board can be set as the structure which attaches a load to the operation | movement which rotates the rotation board by the said trainer 's leg | attachment via a rotation load tool between the said leg bending extension devices. As a rotating load device, a leg bending / stretching device and a rotating plate are connected via a coil spring, and the rotating plate is rotated against these springs to rotate the foot (leg) while applying a load. It is effective for training internal muscles (adductor muscles, abductor muscles, muscles around the hip joint such as the iliopsoas muscle). Further, if the rotating plate is configured as an inclined member that is inclined with respect to the leg flexion and extension device, it can be twisted inward and is effective for further strengthening the pronation muscle of the foot (leg). Conceivable.

On the other hand, the use of training equipment of the present invention will become supine bench, the use of training equipment for expansion and contraction of the foot relative to the leg bending tool according load to obtain a rotational movement of the foot to the leg bending tool A rotating plate is attached, and the leg bending device is rotated by the foot such that a load of only the leg bending device is applied to the foot. That is, when the rotating plate is moved “weakly, smallly and slowly” with the load being the weight of the leg flexion and extension without using a barbell or an array, the pronation muscle of the foot (leg) (the back of the base of the foot) It is effective to train the hip joint muscles. It is also effective to rotate the pair of rotating plates to the inside by the left and right feet.

  According to the present invention, when the rotating plate attached to the leg flexion / extension device is rotated inward or outward with the foot, the pronation muscle of the foot (the leg) (the hip joint muscle at the back of the base of the foot) You can twist and exercise your pronation muscle. In order to increase the load applied to the leg flexion and extension tool, it is done by changing the size of the barbell and array, but in order to reduce the load as much as possible, only the leg flexion and extension tool is used without using the barbell or array. If the rotating plate is moved “weakly, smallly and slowly” to the inside with the weight of, it is effective to train the pronation muscle of the foot (leg) (the hip periarticular muscle at the back of the base of the foot).

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

(First embodiment)
This embodiment, as shown in FIGS. 1-4, base frame F, and benches B was supine such because of the inclined rail Sr inclined is disposed inclined so as to be continuous to the bench B And a leg bending tool K that is movable along the rail Sr. In the middle of the slide rail Sr, a locking projection S1 capable of locking the shaft St interlocking with the leg bending / extension tool K is provided, and below the rail Sr, a gripping portion Sh that the trainer T grips by hand is provided. ing. A connecting portion L1 is provided between the leg bending device K and the shaft St, and a round bar L2 for attaching and detaching the barbell V is attached to the connecting portion L1. Therefore, the load applied to the leg bending / extension tool K can be adjusted by attaching / detaching the barbell V having a different weight to the round bar L2.

  Then, the rotating plates 2A and 2B are attached to the leg bending / extension tool K via the axis J (FIGS. 4A and 4B). The rotating plates 2A and 2B are for obtaining a rotational motion of the foot (twisting motion of the foot), and are a pair of left and right corresponding to the left and right feet, and are constituted by flat plates. The shaft J may be a screw, a screw, or the like, and is rotatable through the plate of the leg bending and stretching tool K. Here, the rotating plates 2A and 2B can be attached to the leg bending / extension tool K via the rotation assisting tool G that assists the rotation, so that the rotating plates 2A and 2B can be smoothly rotated. The rotation assist tool G is a bearing (ball bearing or the like), a screw, a lubricant, or the like. The example shown in FIG. 5 is an example in which a bearing Br is used as the rotation assisting tool G.

Therefore, when performing trainee T is trained using training equipment 1 configured as described above, Ri Do supine trainee T bench Sb, right and left with respect to the pair of rotating plates 2A, 2B of the leg bending device K The posture to perform the expansion / contraction operation is applied with the foot Tf. Since the rotary plates 2A and 2B are rotatable, for example, the legs are twisted outward when the legs are extended, and the legs are twisted inward when the legs are bent (shrinked). That is, if the action of twisting the foot while performing the stretching operation of the foot is performed, the foot can be twisted inward and outward when the foot is bent and stretched, so that the pronation muscle can be trained. The effect of training the pronator muscle is also emphasized in walking, and it is said that in walking, you can train the pronator muscle if you walk on the inside (left and right thumbs), but on the same principle as this The twisting exercise according to the present embodiment can be performed while applying a load with the training device 1, so that the pronation muscle can be further trained.

  In order to increase the load applied to the leg flexor / extension device K (for example, when the athlete trains the pronation muscle), it is preferable to change the size of the barbell V, the array, etc., and reduce the load as much as possible. For this reason, the rotating plates 2A and 2B may be moved by using the load as the weight of the leg flexure / extension tool K without using the barbell V or the array. Further, when the rotating plates 2A and 2B are moved rhythmically in consideration of the hip joint, for example, “weak, small and slow”, the pronation muscle of the foot (leg) (peripheral muscle at the back of the foot joint) is trained. Is effective. There are exercises for preventing rehabilitation of disabled persons and prevention of leg pain of the elderly, etc., when it is good to make the load as small as possible and to move rhythmically “weak, small and slowly” with the hip joint in mind. Further, in order to train the pronation muscle of the foot (leg) (peripheral muscle at the back of the base of the foot), it is effective to rotate the pair of rotating plates 2A and 2B to the inside by the left and right feet, respectively. . The torsional movement of the toes is transmitted to the joints at the base of the knees and feet, so that the deep muscles (pronation muscles) at the base can be stressed and the deep muscles can be trained. In addition, it can be expected to exhibit excellent effects in alleviating foot pain and functional recovery training for the elderly and the like.

  Here, as the configuration of the rotating plates 2A and 2B, as shown in FIGS. 6 (a) and 6 (b), the rotating plates 12A and 12B are configured as inclined members that are inclined with respect to the leg bending extension tool K. It can be attached to the pair of left and right leg flexors and extenders K. In order to train the pronation muscle of the foot (leg) (peripheral hip muscle at the back of the base of the foot), an inward twisting action is effective, but when twisted inward by the rotating plates 12A, 12B, This is because it is considered to be effective for further strengthening the pronation muscle of the foot (leg) (the hip joint muscle in the back of the base of the foot). Here, when the trainee T was experimented with the example shown in FIGS. 1 to 4 and the example shown in FIGS. 6 (a) and 6 (b), the fatigue level of the pronation muscle was shown in FIG. 6 (a). The example shown in (b) was larger. As shown in FIG. 10, leg bending / extension devices K are provided for the left and right feet, and rotating plates 22A and 22B are attached to the leg bending / extension devices Ka and Kb, respectively, to change the degree of expansion / contraction of the left and right feet. It is also possible to use it or to train only one of the left and right feet.

  Further, as shown in FIGS. 7 (a) and 7 (b) and FIG. 8, the rotary plates 2A and 2B are attached via a rotary load tool M that applies a load to the rotation between the leg flexure and extender K. The left and right rotating plates can be configured as rotating plates 22A and 22B that rotate synchronously via the connector R. As the rotation load tool M, the leg bending / extension tool K and the rotation plates 22A and 22B are connected via the coil spring Cb, and the rotation plates 22A and 22B are rotated against the spring Cb while applying a load. Train the pronation of the foot (leg). As the connector R, a gear R can be used so that the rotations of the left and right rotary plates 22A and 22B always coincide. In the example shown in FIGS. 7A and 7B and FIG. 8, a predetermined elongated hole aa is formed in the leg bending extension K, and the rotation distance of the rotating plates 22A and 22B that rotates against the coil spring Cb. Are now regulated.

(Second Embodiment)
In the present embodiment, as shown in FIG. 11, the left leg flexion / extension tool Ka and the right leg flexion / extension tool Kb are independently formed. Also, as shown in FIG. 10, leg bending / extension tools Ka and Kb are provided so as to be movable along the rails Sr and Sr independently on the left and right sides, and move independently according to the bending and stretching movements of the left and right feet. . Therefore, the left and right legs can be alternately bent and extended, or only one leg can be bent and extended. Each of the left and right rails Sr, Sr may be a single guide rail Sr, or may be composed of two guide rails Sra, Srb. The left leg flexor / extension tool Ka and the right leg flexor / extension tool Kb move along the two guide rails Sra and Srb, respectively, so that there is less wobble at the time of movement and the stability is improved.

  As described above, since the load on the muscle can be adjusted, the present invention is suitable for training of athletes and the like, and since a usage method that minimizes the load on the muscle is also possible, It can also be applied to functional recovery training.
