Description

The present invention relates to anterior, posterior tibial muscle and toe strength strengthening devices.

The tibialis anterior muscle is the muscle that runs from the inferior lateral side of the knee to the arch. The tibialis anterior muscle is an important muscle for a person to stand, walk, and run, and is an important muscle that controls the movement of the ankle joint and has a great influence on the knee joint and the hip joint. The tibialis anterior muscle is used as the main action muscle for the dorsiflexion of the ankle joint (lifting the toes), but it has many functions such as balancing while walking, running, and standing. For this reason, the tibialis anterior muscle plays an important role in all sports and exercises performed from standing to standing (eg ball control in soccer). In addition, the tibialis anterior muscle plays a role of normal walking, lifting the toes, and preventing tripping, and when this muscle weakens, it causes tripping and falls.

The tibialis posterior muscle is the plantaris flexor muscle of the ankle joint and is the muscle involved in the formation of the arch inside the plantaris muscle. The tibialis posterior muscle has the following effects. First of all, the action of the tibialis posterior muscle in daily life is the movement of standing on the toes and stretching the back, the role of balancing the ankle, and the adjustment to firmly step on the ground with the sole of the foot when walking. It is used for such things. The action of the tibialis posterior muscle in sports and exercise is to assist the movement of the ankle in judo, running, dashing, jumping, and sports in general. The tibialis posterior muscle is the deepest muscle in the calf that adjusts the ankle. For this reason, when this muscle weakens (weakens), even adults become flat feet.

As mentioned above, strengthening the anterior and posterior tibial muscles is a further sport that moves from standing up, such as improving the motor function of children, improving the competitiveness of athletes, preventing falls (preventing care), and preventing lifestyle-related diseases. It is an important muscle for everything up to the improvement of technology in. However, despite being such an important muscle, the current situation is that there is no device for training the tibialis anterior and posterior tibial muscles.

And, like the tibialis posterior muscle, it is said that raising or stimulating the sole and toes activates the activity of internal organs and is good for health. In addition, the strength of the thumb is especially important for running power, jumping power, and instantaneous power, which are the basic strengths when playing sports, and athletes are trained to strengthen their plantaris and toe strength. There are many people.

On the other hand, the plantaris muscle and toe strength have become weaker due to the influence of lifestyle in recent years, and generally, the big toe is valgus (the big toe is in the direction of the second finger with respect to the center line of the body). There is a growing tendency to become a bending symptom). Such a valgus condition is considered to lead to a decrease in motor function and a decrease in visceral function in oriental medicine. In order to treat and prevent the valgus symptom, the plantaris muscle and toes Strengthening power is said to be the best.

For the purpose of strengthening the plantaris muscle, for example, Patent Document 1 proposes a "plantaris muscle strengthening training board". The "plantaris muscle strengthening training board" proposed in Patent Document 1 has a heel resting portion on which the heels of both the left and right feet are placed, and a foot resting portion on which the toes of both the left and right feet are placed. With the toes of both the left and right feet resting on it, the hooks are projected at positions corresponding to the bases of the toes.

The foot resting portion is slidably attached to the outer frame portion constituting the training board main body, and is always urged forward. With this configuration, it is possible to strengthen the plantaris muscle by hooking a finger on the hooking portion and pulling the foot resting portion alternately on the left and right.

However, if a child or an elderly person with weak plantaris / toe strength uses this training board, he / she cannot pull the foot rest and cannot train the plantaris / toe strength. There was a problem.

Further, there is also a problem that the above-mentioned training board of Patent Document 1 cannot strengthen the above-mentioned tibialis anterior muscle and posterior tibial muscle.

Next, an example of using the tibialis anterior and posterior tibial muscle and the toe strength strengthening device 1 described above will be described. First, as shown in FIG. 4, the heel is placed on the heel mounting plate 4 and the weight is applied. Further, the front portion of the foot other than the heel is placed on the foot mounting plate 6 and the toes are hooked on the hooking portion 7. Then, as shown in FIG. 6, the entire toe pushes the front end of the foot mounting plate 6 downward against the urging of the spring 10. Subsequently, the front end of the foot mounting plate 6 is slowly returned upward so as to resist the urging of the spring 10 with the entire toes. As described above, the tibialis anterior and tibialis posterior muscles can be strengthened by repeating the operations of fixing the heel, pushing the toes, and returning the toes. This exercise can be trained even by people with weak plantaris and toe strength. This exercise can also strengthen the tibialis anterior, tibialis posterior, and toe strength centered on the thumb, peroneus longus, Achilles tendon, gastrocnemius, and soleus.

Further, as shown in FIG. 7, the toes are bent so as to slide the foot mounting plate 6 backward against the urging of the spring 11. Subsequently, the foot mounting plate 6 is slowly returned to the front so as to extend the bent toes and resist the urging of the spring 11. By repeating the above bending and stretching of the toes, the foot mounting plate 6 can be slid back and forth, and can be used for strengthening training of the plantaris muscle and toe strength.

Further, as shown in FIG. 8, with the entire toe pushing the front end of the foot mounting plate 6 downward against the urging of the spring 10, the foot further resists the urging of the spring 11. The toes are bent so as to slide the mounting plate 6 backward. Subsequently, with the entire toe pushing the front end of the foot mounting plate 6 downward against the urging of the spring 10, the bent toe is extended to resist the urging of the spring 11. The footrest plate 6 is slowly returned to the front. After that, the front end of the foot mounting plate 6 is slowly returned upward so as to resist the urging of the spring 10 with the entire toes. With this series of movements, in addition to strengthening the tibialis anterior and tibialis posterior muscles, it is possible to perform strengthening training for the plantaris muscle and toe strength.

According to the above-mentioned tibialis posterior muscle and toe strength strengthening device 1, when the toes are flexed and extended, the toes are easily flexed with a weak force because the front end of the foot mounting plate 6 is only pushed downward. Can be repeated. Since this exercise can be easily performed with a weaker force than the exercise of sliding the footrest plate 6 back and forth, even a person with weak plantaris muscle / toe strength can perform training.

Further, according to the above-mentioned anterior and posterior tibial muscle and toe strength strengthening device 1, the frame portion 2 for supporting the heel mounting plate 4 and the frame portion 2 are arranged below the foot mounting plate 6 and are placed on the frame portion 2. A support plate 8 slidably fitted in the provided slide groove S is provided, and a spring 10 is provided between the foot mounting plate 6 and the support plate 8. As a result, the tibialis anterior and toe force can be used to both swing the front end of the footrest plate 6 up and down and slide the footrest plate 6 back and forth with a simple configuration. The strengthening device 1 can be obtained.

Further, according to the above-mentioned tibialis posterior muscle and toe strength strengthening device 1, the upper surface of the heel mounting plate 4 and the top of the hooking portion are provided at the same height. This makes it possible to strengthen the more ideal tibialis anterior and posterior tibial muscles and toe strength.

Further, according to the above-described embodiment, the foot mounting plate 6 is provided so that the front end can be swung by the connecting portion 9 and the spring 11 provided at the rear end, but the present invention is not limited to this. The foot mounting plate 6 may be configured by using a leaf spring 13 as long as the front end is provided so as to be swingable up and down with the rear end as an axis. As shown in FIG. 9, the leaf spring 13 is composed of a pair of plate portions 13a and 13b facing each other in the vertical direction and a connecting portion 13c connecting the rear ends of the pair of plate portions 13a and 13b. .. The footrest plate 6 is attached to the upper plate portion 13a of the pair of plate portions 13a and 13b, and the support plate 8 is attached to the lower plate portion 13b.

The lower plate portion 13b may be used as the support plate 8 itself without providing the leaf spring 13 and the support plate 8 separately. Further, the plate portion 13a may be used as the foot mounting plate 6 itself on the upper side without separately providing the leaf spring 13 and the foot mounting plate 6.

Further, according to the above-described embodiment, only one spring mounting portion 12 is provided, but the present invention is not limited to this. A plurality of spring mounting portions 12 may be arranged in the front-rear direction. Thereby, the urging force of the spring 11 can be adjusted by selecting the spring mounting portion 12 to which the spring 11 is attached.

Further, in the above-described embodiment, the spring 11 is attached to the support plate 8, but the present invention is not limited to this. It may be attached to the footrest plate 6.
