Description

  The present invention relates to a variable load training device, and more particularly to a plantar training device.

  In an aging society, there are many elderly people who break their bones and fall asleep. In order to prevent this, it is desired to train not only the muscles of the legs and waist but also the plantar muscles, which are the muscles of the soles of the feet. If you train your plantar muscles, when you are about to fall, you can balance it by straddling like a wrestler on the edge of the earth, and avoid falling.

  In various sports competitions, it is preferable to train the plantar muscle group to improve performance and prevent damage to the sole. Furthermore, it is necessary to train the plantar muscle group also in rehabilitation such as plantar fasciitis. If the plantar muscle group is trained, the secondary effect can be expected to be to prevent damage to the ankle, hips, hip joint, and general leg.

  Conventionally, as a method for training the plantar muscle group, a training method for drawing a towel by the strength of the toes or a training method for running on a sandy beach because grip strength of the toes is required.

  A common method of training the plantar muscles using a towel is to lay an ordinary towel flat on a flat floor, place the foot on one end of the towel, and place a load such as a weight on the other end. With the toes and toes bent, the towel is pulled toward the body against the load of the weight, and the contracted towel is stretched again, and the weight is returned to a predetermined position. This is a method for strengthening the muscle strength of the foot by repeating the action of pulling the towel in the body direction again.

  A device having a similar function includes a slide plate that is slidably disposed on a base. The slide plate is loaded with a load that resists sliding, and the slide plate is used as a load. A device in which the toes are slid against the toes and muscles, tendons and sensations of the toes are trained has been proposed (see, for example, Patent Document 1).

According to this device, the muscles, tendons, and sensations of the toes can be trained, and the device can be used in a narrow space such as a room.
JP-A-10-323405

  However, if the slide plate is slidably arranged on the base, there is a problem that the user cannot appropriately train and train the load numerically. In other words, when you want to increase the numerical value of the load as the strength increases by continuously training the toes, or to decrease the numerical value of the load because the strength of the toes declines mainly due to lack of exercise Sometimes, there is a problem that the load cannot be managed with specific numerical values.

In addition, in the method of training using a textile product such as a towel, not only the type of load used as a load means is limited by the shape and weight, but in the case of a towel, the towels are gathered together with toes in the first place. Then, the gathered part accumulates on the arch part, so it is necessary to stretch the towel to the original length, and then gather it together and stretch it, so continue training during that time However, it is forced to rest from the training operation, so it is less efficient than repeating it continuously, and the troublesomeness tends to make the training disgusting.
Furthermore, when using a load (for example, a sand bag), when the towel is stretched to its original length, there is not only inefficiency and troublesomeness that must be removed, but also the load is increased. However, there is a problem that the friction with the floor is increased and the cloth of the towel is damaged or it is difficult to draw it with a toe.

In addition, the method of running on the sand beach requires a sufficiently wide sand beach, and furthermore, because it runs on uneven ground, it is easy to break the balance of the body and there is a high risk of injury. For the purpose of training the plantar muscle group, the burden on tissues such as other muscles and joints is large, and no one can do it regardless of age and gender, individual health condition, exercise ability, and the like.
In addition, it is difficult for the person or third party to objectively grasp how much load is applied to the plantar muscle group by pulling the towel with the strength of the toes or running the sandy beach, It is difficult to judge the effect. Therefore, there is a problem that it is not suitable for performing effective training according to the individual purpose.

  Therefore, an object of the present invention is to provide a plantar training apparatus capable of training while effectively managing training conditions according to the user's exercise ability.

The present invention is such that the support frame for the weight of the user and the footrest plate on which at least the toes of the user's feet are placed, one is fixed and the other is movable with respect to it.
The above-mentioned problem has been solved by a sole training device characterized in that the movement can be controlled by an adjustable load means.

  According to the present invention, it is possible to appropriately adjust the numerical value of the load so as to adapt to the user's body shape and athletic ability, etc., so that while managing the training conditions according to the purpose of the user You can train efficiently. In addition, the plantar can be trained even in limited places such as indoors.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a view of the training device 10 as viewed from above.
FIG. 3 is a view of the training device 10 as viewed from the side.
FIG. 4 is a view of the training device 10 as seen from the rear.
FIG. 5 is a perspective view showing a state in which the chair support frame 11 a is separated from the main body frame 11 of the training apparatus 10.

  1 to 4, the training apparatus 10 includes a slider 14 which is a “footrest plate” in the claims, and the slider 14 is provided with a cylindrical hollow portion (not shown), and a body frame is provided in the hollow portion. 11, the guide rails 12a and 12b, which are fixedly arranged side by side, are inserted, whereby the slider 14 is movably supported by the guide rails 12a and 12b.

  Further, since the stoppers 16a and 16b are interposed between the guide rails 12a and 12b and the slider 14, the stoppers 16a and 16b regulate the moving range of the slider 14, and the slider 14 and the load means 30 are connected to the pulley 17. , 18 and 19 to be linked to each other by a wire 28.

A chair 42 on which a user is seated is attached to a chair support frame 11a which is a “support frame” in the claims. The chair 42 is supported by a chair support base 34 so that the height of the chair can be adjusted. The connecting portion 32 is supported by the chair support frame 11a so as to be detachable.
Further, by providing the chair 42 with the front / rear adjustment mechanism 38, the position of the chair 42 can be adjusted in the longitudinal direction of the main body frame 11 in accordance with the body shape of the user within the allowable range of the front / rear adjustment frame 36.
Further, the chair 42 is provided with grips 40a and 40b on the left and right sides so that the user can easily grip the grips 40a and 40b during exercise to ensure balance of the body.

  The foot stabilizing member 26 is fixed to the chair support frame 11a, and enables the foot stabilizing member 26 to stabilize the foot during exercise. The chair support frame 11a and the foot stabilization member 26 may be configured to be removable. Further, in order to be able to adjust the height according to the shape and size of the user's foot, the position of the foot pressing rod 22 of the foot stabilizing member 26 can be adjusted, and the position can be adjusted using a lock mechanism. The structure can be fixed.

A heel support member 20 is laid on the chair support frame 11a.
Preferably, the heel support member 20 is such that the heel does not slip easily when the heel is placed, and the toes and toes are likely to come into contact with the slider 14, and the bending operation of the foot when bending the tip of the foot. The surface is processed so that the load is applied to the end of the foot and it is easy to bend the tip of the foot.

As described above, the foot holding rod 22 is provided so that the position can be adjusted.
By doing so, the user can perform training when the foot holding rod 22 of the foot stabilizing member 26 is adjusted to be positioned above the instep of the foot, and the height of the foot holding rod 22 can move the instep. Two kinds of training can be performed when the position of the foot placed on the heel support member 20 is stabilized by being adjusted to the pressing position.
For example, when the foot holding rod 22 is adjusted to a position where it does not come into contact with the instep of the foot and the slider 14 is pulled toward the body by the muscle strength of the foot, the instep is pressed by the foot holding rod 22. Absent. As a result, the degree of freedom of the joints of the toes and ankles is increased, and by bending the toes while bending the instep, there is an effect that the calf muscles can be simultaneously trained in addition to the plantar muscles.
On the other hand, when the height of the foot holding rod 22 is adjusted to a position to hold the instep, the foot holding rod 22 limits the bending of the instep and bends the toe with little action on the calf muscle. Will perform the action. This is suitable for a training method when it is desired to concentrate the training effect on the plantar muscle group.

Hold with your toes.

In this state, the slider 14 is attracted so as to move to the body side by the muscle strength of the foot against the load of the load means 30 connected to the wire 28. The resistance as a load with respect to this pulling motion can be controlled by the number of weights of the load means 30. In addition, training operation is stabilized by ensuring the balance of the body using the grips 40a and 40b provided in the chair 42.
Next, when the force of the foot is removed from the state in which the slider 14 is pulled toward the body side, the slider 14 returns to the original position where it abuts against the stoppers 16a and 16b due to the load of the load means 30 transmitted through the wire 28. Return.
The effect of the training varies depending on the number of times that the series of operations are repeated or the magnitude of the load.
As the load means 30, as shown in FIG. 1, a well-known one that can change the load by adjusting the number of weights using a stop rod 31 can be used.

  Also, in order to transmit the muscular strength of the foot as it is to the slider 14 without slipping the contact portion between the foot and the slider 14, is it laid on the surface of the slider 14 made of an elastic material such as rubber or sponge rubber?
