Description

  The present invention relates to a balance shoe that is useful for training muscles and attaching a correct posture.

As described in Patent Document 1, a balance disk (also known as a balance cushion) is obtained by injecting air into a hollow portion of a slightly stiffer cushion body. It is said that, in order to balance from the unstable state, not only the sense of balance can be nurtured but also the inner muscle of the trunk can be effectively trained.
Thus, the balance disk is a cushion body and is assumed to be used on the floor surface. In addition, it weighs about 1kg, and the size of the disc itself is appropriate. If you use both feet on the two discs, you will need two discs, so it is not easy to carry around. In many cases, it is used indoors, such as at home or sports facilities.

  On the other hand, in sports training, training of a sense of balance and strengthening of various muscles including the trunk are required in accordance with the sport. For example, in golf swing practice, you can develop a sense of swing balance so that you can smoothly receive the drag from the ground and rotate the body smoothly, and strengthen the torsion muscles to make the swing movement smooth It is requested to do. Also, in skiing practice, on a sloping ground or uneven ground, keep the stable state while constantly changing from the state of unbalanced on one side to the state of unbalanced on the other side, and the muscles that maintain it There is a need to strengthen.

Also, in recent years, an increasing number of people are engaged in long-time desk work using personal computers. Among them, the posture of the back during desk work becomes a habit, putting a burden on the shoulders and neck, stiff shoulders, low back pain, knee pain Many people are suffering from various symptoms.
Furthermore, many modern women have O-legs or X-legs, but if left untreated, they will not only look bad, but their legs may edema. In some cases, distortion of the pelvis is the cause, and since the pelvis serves as a foundation to support the body above it, it also adversely affects metabolism.
In this way, interest in improving posture has been increasing rapidly, but in order to maintain the correct posture, the correct posture in daily life is effective.

Utility Model Registration No. 3204734

  The present invention has been made paying attention to the above-mentioned conventional problems, and utilizes the idea of training a sense of balance and strengthening muscles by using a balance disk, and corrects the correct posture in sports practice and daily life as described above.

The present invention relates to a balance shoe. Specifically, a balance over shoe to be worn while wearing shoes such as athletic shoes and a balance sandal-like shoe to be worn while wearing bare feet or socks are assumed.
A balance over shoe 1 according to a first embodiment of the present invention will be described with reference to FIGS.
This balance over shoe 1 is made of EVA resin as a raw material, is integrally formed by injection molding, has a solid structure, and has no hollow portion. EVA resin is lighter and more elastic and flexible than polyethylene, is durable and hard to tear, and has been conventionally used as a material for sandals.

The sole portion 3 of the balance over shoe 1 is lacking on the toe side and the heel side, and the remaining upper surface 5 receives the sole on the sole side, and the toe side is on the heel side along the shoe outline. Designed wider than.
The upper surface 5 is flat, and an arrow 7 indicating the insertion direction of the foot is printed on the heel side. The lower surface 9 side has a bowl shape and gently bulges downward, and the convex top 11 forms the bottom. In addition, although the several hollow 13 is formed in semicircle shape at the convex top part 11 side, this is provided for the convenience at the time of injection molding.

The sole portion 3 is designed on the basis of a portion facing the arch of the foot (strictly speaking, the arch of the three arches that hangs from the thumb to the heel).
The overall size of the upper surface 5 is designed so that the central portion is directly under the arch. In addition, the convex top 11 is designed to be directly below the arch on the lower surface 9 side. When the body weight is received, the periphery of the convex top portion 11 is compressed and the ground contact portion W is formed, so that the body weight is received with the ground contact portion W as a fulcrum.

The balance over shoe 1 has an area W of a ground contact portion with the ground surface or the floor surface corresponding to the shape of the bowl. If the existing balance disk is a surface shape, the balance over shoe 1 has a dot shape. It can be said.
Therefore, when the balance over shoe 1 is worn, the toe side and the heel side are in a state of playing without touching the ground, so the weight is supported only by the portion surrounding the arch. Moreover, the footwear swings in all directions including not only the toe to heel direction but also the left and right sides. For this reason, in order to achieve a desired posture and movement, the various muscles of the entire body are used well and balanced.

The pair of holding pieces 15, 15 rises upward from the peripheral portions on the left and right sides on the upper surface 5 side of the sole portion 3. The holding pieces 15 and 15 are gently curved in a direction approaching each other, and their tips are opposed to each other with a slight gap.
The sole portion 3 and the pair of holding pieces 15 and 15 are formed into a substantially cylindrical shape, and the pair of holding pieces 15 and 15 hold the back side of the foot.
Since the holding pieces 15 and 15 can be elastically expanded, even if the height of the shoe upper is different, it is possible to cope.
In addition, after the balance over shoe 1 is worn, the shoe elastically contacts the inside of the cylindrical body surrounded by the pair of holding pieces 15 and 15 having elasticity and flexibility and the sole portion 3, so that the shoe fits. It is hard to come off.

In the present embodiment, the balance over shoe 1 is a one-size specification, and it is a junior (weight: about 30 kg, shoe size: about 20 cm) to a large adult male (weight: about 90 kg, shoe size: about 29 cm). Dimensions are set so that it can handle up to
That is, the length dimension of the upper surface 5 of the sole portion 3 is set to about 170 mm and the width dimension is set to about 140 mm.

Further, the distance dimension from the upper surface 5 of the sole portion 3 to the convex top portion 11 on the lower surface 9 side is an appropriate range of about 35 to 45 mm, and among them, about 40 mm is preferable as shown in the drawing.
Within this range, due to the elasticity of the EVA material, when the weight of about 30 to 90 kg is received, the lower surface 9 side is slightly recessed, and the area of the grounding portion W formed surrounding the convex top portion 11 has a length dimension. It is assumed that the width is about 105 to 115 mm and the width dimension is about 75 to 85 mm. In the drawing, the grounding portion W is shown in a rectangular shape having a length dimension of about 110 mm and a width dimension of about 80 mm, but this is drawn for the convenience of visual recognition. W does not have a rectangular shape, and when the person wearing it moves, the ground contact portion W also moves slightly.

FIG. 3 shows a state where the balance over shoe 1 is worn while the athletic shoe S is worn. The balance over shoe 1 is integrated with the athletic shoe S, and looks like a single tooth clog when viewed from the left and right sides. The weight is received with the ground contact portion W formed on the lower surface 9 of the sole portion 3 as a fulcrum.
Therefore, if the standing posture as shown in FIG. 4 is continued, the center of gravity of the neck is placed immediately above the ankle, and the entire center of gravity is straightened, so that a correct standing posture is obtained. In this correct standing posture, as shown in detail in FIG. 5A, the center of gravity point (indicated by ●) of each part is aligned with the balance line L.

5 (B), (C), and (D) are not correct postures, and the center-of-gravity point of each part is off the balance line L, but can stand normally in normal daily life. However, when the balance overshoes 1 are worn, the balance must be achieved without depending on the heel side and the toe side. It cannot continue and instinctively changes to the correct standing posture shown in FIG.
If this correct posture becomes jealous, not only front-rear but also left-right displacement will be corrected. That is, the stoop that is likely to be a person engaged in long-time desk work is corrected. Also, if the posture is corrected by self-flow, it tends to be warped and waisted, but it does not become warped and waisted. Furthermore, since the center of gravity point of the knee is shifted from the balance line L for the O-leg and the X-leg, it is improved if the posture of FIG.

In addition, since you can move around while wearing the balance overshoes 1, you can exercise while keeping balance.
That is, as shown in the upper side of FIG. 6, (1) not only standing posture, but also (2) walking, (3) kick, and (4) using a chair to bend in a direction with weak muscle strength. Can do.
Moreover, as shown in the lower side of FIG. 6, (1) Stand with both legs widened to the left and right, twist the upper body, (2) Stand with both legs widened back and forth, and fall forward and backward, (3) Standing with your legs spread to the left and right, you can train various muscles with various movements, such as stretching the upper body with the center of gravity lowered, and (4) doing squats.

  As described above, since the user can freely move around the ground with slopes and irregularities regardless of whether indoors or outdoors, the balance over shoe 1 can be used for skiing practice.

FIG. 7 shows a case where golf swing practice is performed. (1) By only giving an address, it becomes a core balance address.
Also, before actually hitting the club C and hitting the ball B, (2) When swinging a half swing or (3) When swinging a full swing, if you wear the balance over shoes 1, It becomes practice to take swing balance. Since the balance over shoe 1 does not have a hollow portion, the ground drag can be sensibly confirmed. In addition, this practice is very effective because of the high accuracy of vertical movement.
Furthermore, it is recommended for advanced users to use (4) one-leg standing shots.

A balanced sandal-like shoe 17 according to a second embodiment of the present invention will be described with reference to FIG.
The balance sandal-like shoe 17 is integrally molded by injection molding using the same material as the balance over shoe 1, and the overall shape is also similar. Accordingly, the same parts are denoted by the same reference numerals and the description thereof is omitted.
The balance sandal-like shoe 17 is assumed to be worn with bare feet or socks, and the entire size is reduced accordingly.

FIGS. 9A and 9B show a state of wearing with bare feet, and the bare feet are inserted into the cylindrical body surrounded by the pair of holding pieces 15 and 15 and the sole portion 3 to be elastically contacted. So it fits bare feet and is difficult to come off.
Because it can be worn as if you were wearing sandals, you can easily use it as indoors at work or at home without exercising and enthusiastically. It can be remembered.

A balanced sandal-like shoe 19 according to a third embodiment of the present invention will be described with reference to FIG.
In the balance sandal-like shoe 19, the upper surface 5 of the sole portion 3 of the balance sandal-like shoe 17 is raised in a mountain shape to form a raised portion 21. When the balance sandal-like shoes 19 are worn, this raised portion 21 pushes the point on the sole, so that a massage effect can be expected.

A balanced sandal-like shoe 23 according to a fourth embodiment of the present invention will be described with reference to FIG.
This balance sandal-like shoe 23 is provided with one belt 25 instead of the pair of holding pieces 15, 15 of the balance sandal-like shoe 17. In the case of putting on with bare feet or socks on, it is only necessary to insert from the toe side. Therefore, the upper side can be constituted by the belt 25 to form a complete cylindrical body. If the belt 25 is used, the belt 25 fits all around the slippery bare feet and socks, making it even more difficult to remove.
If the belt 25 is used, it is difficult to uniformly cope with various sizes and heights of the insteps of the person wearing the belt 25. However, it is possible to cope with this by providing several sizes such as S, M, and L.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, the balance over shoes are expected to be applicable to baseball swing practice, trail running practice, and also hammer throwing and disc throwing practice.
Moreover, the balance sandal-like shoes can be used not only for indoor wear but also for outside wear when going out to the garden or veranda.
