Abstract

PROBLEM TO BE SOLVED: To provide footwear configured to improve a sense of balance to enhance training effects, as well as advancing functional effects such as walking or running.SOLUTION: The footwear is unstable footwear such as shoes, slippers or clogs with a ground contact surface which is curved in a longitudinal convex shape. The convex curve is circularly curved from the heel to the root of toes and extended toward the toes, to make the toes turned upward, or to make the portion forward of the root of toes linearly turned upward. Thus, the convex curve is reduced to minimize the resistance from landing to leaving. Particularly, the toes kick the ground immediately before leaving, to naturally increase the stride and achieve quick motion, thereby increasing the effect of facilitating running and walking and increasing speed. Footwear having convex curves formed in the longitudinal direction and lateral direction can be used as welfare, rehabilitation and health maintenance equipment for improving a sense of balance in addition to motional effects.

  The present invention relates to footwear and a training device having a training function and enhancing a forward function.

The grounding part of the tooth part is a convex curved surface in the pitching and swinging direction, and extends from the front side of the insertion hole of the ridge of the base part to the rear side of the insertion hole of both ends of the cord. An unstable clog is proposed in which the front side and the rear side of the convex curved surface of the ground contact portion are different from each other in curvature, and the curvature of the rear side is larger than that of the front side. (See Patent Document 1).

Japanese Patent No. 4031558

The problem with the invention of Patent Document 1 is that the portion where the sole touches is straight from the tip of the toe to the heel, so that the entire sole is being balanced. Therefore, the effect of balancing using the ankle, knee and hip muscles was insufficient. Since the fingers are difficult to spread, there is a problem that the hallux valgus is less effective, and the walking speed does not become faster, so there is less aerobic exercise effect. Moreover, the rehabilitation effect, the balance taking effect, and the muscular strength improvement effect were insufficient. Also, the forward function could not be enhanced.

  In order to solve the problem, the present invention not only can create an unstable state by wearing it, but also to improve the training effect etc. It provides footwear that can easily increase forward function effects such as walking, running, etc.

In order to achieve the above object, the footwear of the invention of claim 1 is an unstable footwear in which the ground contact surface of footwear such as shoes, slippers, clogs, etc. has a convex curved surface in the front-rear direction. The convex curved surface is an arc curved surface from the base of the foot to the base of the toe, extending it in the direction of the toes, or pointing the toes upward, or pointing the tip from the base of the toes upward on a straight line And

The footwear according to claim 2 is characterized in that the ground contact surface of the footwear is a convex curved surface in the left-right direction cross section.

According to a third aspect of the present invention, there is provided a footwear according to the first or second aspect, wherein a space is provided between the bottom of the footwear and the surface in contact with the sole, and a sealed bag is inserted into the space, and a gas or liquid is inserted into the bag. A bag body in which a jelly-like substance, a sand-like or granular object is inserted, or a bag body in which the bag body has a cushioning effect and is flexible and has a shape that stimulates the sole on the upper surface. Is characterized in that it can be exchanged.

According to a fourth aspect of the present invention, the footwear according to the first or second aspect is characterized in that a protrusion and / or a cushion is provided on a surface where the sole of the footwear contacts.

The footwear according to claim 5 is characterized in that the toe interval expanding piece disposed between the toes in any one of claims 1 to 4 has a size and a hardness for expanding the interval between the toes. Features.

The footwear according to claim 6 is an unstable footwear in which the back surface of footwear such as shoes, slippers, clogs, etc. has a convex curved surface in the front-rear direction as shown in FIG. It is characterized by adjusting using a mountain-shaped bottom with a high fingertip and a low finger base.

According to a seventh aspect of the present invention, the footwear according to the fifth or sixth aspect is characterized in that a toe-spacing extension piece is provided on the sole of the footwear with a gap between the fingers.

The footwear according to claim 8 can be attached / detached by stopping the bottom portion of the convex curved surface with a string or belt, with a velcro-like thing, or with a hook-like thing in any of claims 1 to 7. It is characterized by that.

The effect of the invention of claim 1 is that the convex curved surface becomes smaller when the fingertip is directed upward, the effect of moving forward is increased even if no force is applied when moving forward, the stride is naturally increased, and walking and running speed are increased. Will be faster. As a result, the aerobic exercise effect is increased and the fat is burned and the body fat is reduced. If the convex curved surface is made smaller, instability will increase, and the effect of balancing the ankle, knee, and waist and the effect of strengthening the muscular strength will increase. In the conventional technology, the contact surface of the sole is a flat surface, and the fingertip does not face upward, so that such an effect cannot be obtained.

FIG. 1 shows an overall view when footwear is worn. FIG. 5 shows the landing state, landing from the heel portion, FIG. 6 shows the state in which the foot is almost vertical, FIG. 7 shows the state before the landing where the tip of the footwear has touched the ground, upward The position of the finger comes to the lowest position and the body is pushed forward. Since the ground is naturally kicked, it is easy to push the weight forward, it is easy to get out before normal running and walking, the speed is increased, and the stride is also larger than usual. FIG. 4 is a view from the front. A convex curved surface opens depending on body weight, and a cushioning effect is also obtained.

In this way, it is possible to move smoothly from landing to takeoff, and in particular, it is not possible to take off while kicking the ground naturally at the toes.

When the convex curved surface reaches the center ground contact portion (B), the weight is lifted step by step by the footwear height H (2 to 5 cm). Although I do not feel the burden, even if I set H to 3 cm, it consumes energy to lift my body weight by 1,000 steps, and even if I walk the same distance, this effect is different, so fat burning effect and muscle strength increasing effect are great.

In this way, by moving the finger upwards, resistance can be minimized from landing to takeoff, and running and walking can be performed with less force. Since the kicking force increases and the stride naturally moves faster and faster, the walking and running speed can be easily increased. The effect of forward function and aerobic exercise are also improved.

Since the fingertip part D faces upward, the toe is caught and does not fall down, so that it can be used as a fall footing prevention and safety footwear. This is also an advantage that cannot be obtained by the conventional technology.

Furthermore, in the center ground contact portion B of FIG. 6, the footwear has a thicker thickness H, and the walking posture is more beautiful than a high heel.
In particular, you can drive beautifully, smartly, and walk naturally without having to be conscious of it, because it is not a fuzzy running or walking, but rather a swipe.
Therefore, the willingness to run and walk with the footwear is increased, the number of trainings and the distance are increased, the object of the present invention is achieved, and the effect is improved.

If the toes are pointed upwards, the space between the fingers will open, and the therapeutic and preventive effects on hallux valgus will also increase. This effect is not possible with conventional technology.

The effect of the invention of claim 2 is that the back surface of the footwear forms a convex curved surface in the front-rear direction and the cross section in the left-right direction is also a convex curved surface, so that the ankle can be easily tilted to the left and right, and more muscles to balance. Because the nerves are used, the aerobic exercise effect is improved by further strengthening the ankle, leg, and muscles of the body and the body. Effective as welfare equipment and anti-aging equipment.

The effect of the invention of claim 3 is that a space is provided between the sole and the sole of the footwear, a sealed bag is inserted into the space, and a gas, liquid, jelly-like substance, sand or granular material is inserted into the bag. A bag body in which an object is inserted, or a bag body in which the bag body has a cushioning effect and is flexible and has a shape that stimulates the sole on the upper surface.

It is the figure which inserted the protrusion-shaped sheet | seat between the sole and the footwear bottom. It is a top view which provided the member which expands between toes. It is a figure which shows the state which made the toe horizontal with the footwear which enabled adjustment of the upward angle of the toe. It is a figure which shows the normal state which made the toe upward with the footwear which enabled adjustment of the upward angle of the toe.

The footwear of the present invention will be described with reference to FIGS.
The footwear of the present invention is an unstable footwear in which the ground contact surface of footwear such as shoes, slippers, clogs, etc. forms a convex curved surface in the front-rear direction, and the convex curved surface is an arc from the foot heel to the base of the toe The curved surface is extended in the toe direction so that the toes are directed upward, or the tip of the toes is directed straight up.

In FIG. 1, 1 is a foot, 2 is footwear, 3 is a toe, and 4 is a space between the footwear and the foot.
First, as shown in FIG. 1 for explaining the ground contact surface, the bottom ground contact surface of the footwear has an arc-shaped convex curved surface, the ground contact surface A is the position of the heel, B is the center portion, C is the base of the finger, and D is the fingertip. The finger part 3 faces upward.
The ground contact portion with the ground G is made of a non-slip material such as rubber, and has an uneven shape with resistance so as not to slip. The curved base material may have spring-like elasticity, and may have a cushioning effect that opens the curved surface according to body weight.

FIG. 4 has no convex curved surface in the left-right direction, and enhances the effect of running and walking. At first, use a low height H, increase it as you get used, and use a height suitable for the purpose of rehabilitation, running, etc.

The convex curved surface of the footwear is formed in an arc shape between the heel A and the toe root C, and when it is extended to the toe D , the toe naturally faces upward. Alternatively, as shown in FIG. 2, the tip from the base of the toes may be straight upward. If the height H is increased, the convex surface becomes smaller and the instability effect increases. The height H is desirably about 2 to 5 cm, and the angle R is preferably about 20 to 50 degrees. The material is a little cushioning, such as rubber.

This will be described below with reference to FIGS.
The ground contact between the convex surface of the footwear and the ground is landed from the heel portion of FIG. 5 landing position (A), moves to the central ground surface (thickest portion) in FIG. ) To pass through to the toe part of the toe part of the toe part (D) and the toe part of the toe part (D) corresponding to the base part of the finger. Take off the ground while kicking (pushing) the ground on the surface of the ground contact surface (D).

When the convex curved surface reaches the center ground contact portion (B), the weight is lifted step by step by the footwear height H (2 to 5 cm). Although I do not feel the burden, even if I set H to 3cm, it consumes energy to lift my weight by 30m in 1,000 steps, and there is a considerable difference in walking the same distance compared to conventional footwear, the fat burning effect The effect of increasing muscle strength is great.

The effect is that the convex curved surface becomes smaller by pointing the fingertip upward, and the effect of moving forward is increased even if no force is applied when moving forward, the step length is naturally increased, and walking and running speed are increased. If the convex curved surface is made smaller, instability increases, and there is an effect of balancing the ankle, knee and waist, and an effect of strengthening muscle strength.

In this way, by moving the finger upwards, resistance can be minimized from landing to takeoff, and running and walking can be performed with less force. Since it comes out naturally and the stride moves naturally and quickly, there is an effect that the speed of walking and running becomes easy easily. The effect of forward function and aerobic exercise are also improved.

Since the fingertip part D faces upward, the toe is caught and does not fall down, so that it can be used as a fall footing prevention and safety footwear.

Further, in the center ground contact portion B in FIG. 6, the thickness H of the footwear is increased, and the walking posture is more straight than the high heels, and the driving and walking posture is beautiful.
In particular, you can make beautiful smart driving and walking naturally without having to be conscious of it, because it is not a running or walking that makes a noise.
Therefore, the willingness to run and walk with the footwear is increased, the number of trainings and the distance are increased, the object of the present invention is achieved, and the effect is improved.

If the toes are pointed upwards, the space between the fingers will open, and the therapeutic and preventive effects on hallux valgus will also increase.

The footwear material can be changed according to the purpose of use. For example, light materials can be used for running, and heavy materials can be used for strengthening leg muscles.

As shown in FIG. 3, there is a form in which the ground contact surface has a convex curved surface in the left-right direction.
In FIG. 3, the convex curved surface is formed in the front-rear direction and the left-right direction, and the central ground surface B of the footwear is easy to tilt left and right and is unstable. In addition to exercise effects, it is used as welfare equipment, rehabilitation equipment, health maintenance equipment as a means to train the sense of balance.

By raising the finger, the convex curved surface becomes smaller than that of the horizontal finger, so that the instability in the left-right direction increases and a better form is obtained.
