Description

Technical Field

[0001] The present invention relates to the field of ergonomics, and particularly to a shoe that changes the walking movement trajectory of humans. Background Art

[0002] Nowadays, people have means of transportation such as cars and high-speed rails when traveling, and there are also environmentally friendly and convenient bicycles. In fact, the most environmentally friendly and convenient means of transportation is the pair of legs given to us by our mother. These feet can climb mountains, run, wade through water and travel long distances. However, with the expansion of people's social activity range and the strengthening of the sense of time, traveling on foot is slow, has a short journey and consumes a large amount of physical strength, which can no longer meet people's needs for fast and easy travel.

[0003] How to reduce physical energy consumption during walking, improve walking speed and journey is a major problem in ergonomics that has remained unsolved for thousands of years.

[0004] The author has explored human walking and physical energy consumption for nearly thirty years and found in the study of the decomposed movements of human walking that:

[0005] When the right foot takes a step forward and the heel is above the ground, Figure 1 a. The center of gravity of the human body moves forward between the two feet, Figure 1 in f, the balance is lost, causing the right foot to fall instantly and the heel to impact the ground. Figure 1 b. At this time, the height of the pedestrian (the height from the top of the pedestrian's head to the ground) drops to the lowest point. The right foot drags and supports the body to move forward and lift (lift the body weight). At the same time, the left foot pushes and supports the body to move forward and lift. When the left foot leaves the ground and steps forward past the right foot, the right foot stands independently on the ground. Figure 1 c. The entire body weight of the pedestrian moves forward to the independent right foot. At this time, the height of the pedestrian rises to the highest point (approximately equal to the standing height of the pedestrian). Repeat the first sentence of this paragraph, and the left foot takes a step forward, Figure 1 d. Figure 1 e. Just change the right to the left.

[0006] From the above description of the decomposed walking and the wavy trajectory of human walking movement Figure 1 it can be seen that the force that the legs and feet actually use to push people forward, such as the right foot dragging and the left foot pushing as described above, is only a very small part of the physical energy consumption during walking. (For example, a person weighing 75 kg walks at 6 km / h, and the calculated power is approximately 0.042 kW), and most of the physical energy during walking is consumed in the following two places that are not beneficial to walking and are harmful. The specific manifestations are:

[0007] First: The heel impacts the ground during walking. See Figure 1 a. Figure 1b. This impact force causes the heel of the pedestrian to bear 1.5 to 2 times their own body weight (for example, when walking in goose step, the force borne by the soles of the feet is 3 times the body weight), and with each step, the heel impacts the ground once. Such continuous and frequent impact forces not only consume the pedestrian's physical energy but also affect walking speed and endurance. Most importantly, it is also related to orthopedic diseases that cause self-harm and injury to the walking body.

[0008] According to the discussion of human evolution data, after humans evolved from quadrupedal crawling to bipedal walking, it brought many advantages: such as freeing the hands, facilitating the manufacture and use of tools; placing important organs such as the brain and eyes in a higher position, enabling a wider and farther view. This visual advantage promoted the evolution of the human brain and led humans towards civilization. However, human bipedal walking also brought many negative problems: such as the entire weight of the body shifting to the feet, subjecting the human spine and lower limbs to greater compression. With each step taken during walking, the inertial force exceeding the body weight presses down once, and if walking continues, it continuously impacts and squeezes the lumbar spine and lower limb joints, resulting in problems of spinal and joint injuries for humans. Such as lumbar disc herniation and spinal scoliosis, hip arthritis and femoral head necrosis, etc. (Animal medical research reports that quadrupedal reptiles do not have such diseases). These conditions are hidden with a relatively low incidence rate when people are young. As people age, the spine, hips, knee joints, menisci, etc. cannot withstand the continuous squeezing caused by walking over the years, and the diseases gradually appear and become severe, resulting in an inability to straighten the waist or bend the knees, and even difficulties in walking or being bedridden, leading to a poor quality of life.

[0009] Second, during the walking process, the body weight is lifted, such as Figure 1 b, c. Taking Figure 1 as an example: A person is 1.7 meters tall, the step length S is 0.64 meters, the measured height difference h between the highest point g and the lowest point i of the walking height is 0.064 meters, the body weight is 75 kilograms, and walks 6000 meters per hour.

[0010] From the above parameters, it can be seen that with each step, the 75-kilogram body weight is lifted by 0.064 meters.

[0011] The number of steps walked in one hour: the walking distance in one hour ÷ step length (S), that is: 6000 meters / hour ÷ 0.64 meters = 9375 steps / hour,

[0012] The height lifted in one hour: the height of one step (h) × the number of steps per hour, that is: 0.064 meters × 9375 steps / hour = 600 meters / hour.

[0013] That is to say, by walking for one hour, the walking person (with a body weight of 75 kilograms) can be lifted to a height of 600 meters. This is the wasted useless work during walking and also an important reason for the large consumption of human walking physical energy.

[0014] Power required to lift one's own body weight (75 kg) to a height of 600 meters: 600 meters / 3600 seconds = 0.17 horsepower (about 0.125 kW), which is approximately 3 times the power of 0.042 kW required for walking 6 kilometers per hour as mentioned above.

[0015] (Note: 1 horsepower is equal to 75 kg·m / s, that is, lifting a 75 kg heavy object to a height of 1 meter in 1 second.)

[0016] For continuous lifting of one's own body weight, as described in "one", it also causes damage to the spine, lower limb joints, etc. of the walker due to long-term repeated squeezing.

[0017] The main reason for the above problems is that when a person walks, their height fluctuates, that is, the walking trajectory is a wavy motion, as shown by the j wavy dotted line in Figure 1 . If it moves in a horizontal straight line trajectory like a wheeled vehicle, the above problems will no longer exist. Then, how to change the walking wavy trajectory into a horizontal straight line trajectory? It is impossible to solve this problem by improving the human body's own skills. Only by innovating a pair of shoes worn on the feet that can complement the walking wavy trajectory in real time and change the walking wavy motion trajectory into a horizontal straight line or a nearly horizontal straight line is the guiding direction for in-depth research on solving this problem.

[0018] Regarding shoe research, there are many patents in recent years, but they all focus on aspects such as wearing beauty and durability. There are also patents for shoes with shock absorption, comfort, and convenience for running, such as the existing patents: ZL201920798981.7, fitness shoes; ZL201911064693.X, boosting shoes. These patents have not yet addressed the important issue of using the compression deformation and elastic force increase and decrease of the elastic pad on the sole to change the wavy trajectory that has hindered human walking for thousands of years.

[0019] Therefore, how to change the human walking wavy trajectory into a horizontal straight line trajectory, as shown by the k horizontal dotted line in Figure 2 , and consume most of the extra weight lifted during walking to increase walking speed and distance, which is of course for the public to use. Summary of the Invention

[0041] Specific implementation method

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Walking conditions of wearing the shoes of the present invention:

[0044] The right foot takes a step forward, Figure 2 a. The upward warping surface 11 of the elastic pad at the heel touches the ground, Figure 2 b. (1. When the upward warping surface 11 touches the ground, the deformation distance L of the elastic pad can be reduced; 2. The elastic pad at the heel fills the gap between the sole and the ground, so that the height during the step does not decrease; 3. To avoid the foot falling empty and the heel not directly falling and impacting the ground, causing lumbar spine and joint injuries.) As the right foot descends and compresses the elastic pad until the right foot stands upright on the ground, Figure 2c. (Elastic pad compression energy storage stop.) The height also rises from low to the highest, while the elastic pad is compressed by the body weight from high to the lowest. This rise and fall are complementary to keep the height unchanged, maintaining the walking trajectory in the best energy-saving walking state of a horizontal straight line. (Avoid lifting one's own body weight and consuming physical strength.) At the same time, the elastic pad on the left shoe heel behind the right foot releases elastic force to boost the left foot. The boosting force moves from the shoe heel to the forward-arching arc 8 of the sole, (facilitating smooth transition, maintaining height and reducing resistance.) until it bounces off the ground at the front of the shoe, and the left foot takes a step forward. Figure 2 d and Figure 2 e. Repeat this paragraph, just switch the right to the left, and the purpose of achieving a horizontal straight-line walking trajectory can be achieved.

[0045] Example 1: Figure 3 Single-layer elastic foam pad shoes and schematic diagram of the compression deformation L of the foam pad, Figure 4 Front-back two-layer elastic foam pad shoes, Figure 5 Double-layer elastic foam pad group shoes, Figure 6 Front-two-back three-layer elastic foam pad group shoes. The elastic pad 3 is set as more than one elastic foam pad. Each foam pad is provided with more than one hole 9 under the shoe sole, and the hole depth reaches up to the upper bottom 2. Elastic foam rods 10 can be inlaid in the holes. The elastic foam rods are similar to the elastic foam pads. The foam rods are made of various foaming materials with different lengths and densities, having strong and weak elastic forces. According to the body weight of the pedestrian, elastic foam rods with appropriate elastic forces can be inlaid, replaced or increased or decreased in the holes 9 until the walking movement trajectory basically maintains a horizontal straight line.

[0046] Example 2: Figure 7 , Figure 8 It is a single-layer air cushion group shoes, with more than one elastic air cushion set. Each air cushion is provided with an inflation nozzle 12. According to the body weight of the pedestrian, use an air pump to connect to the inflation nozzle to inflate each air cushion, and adjust the air pressure in each air cushion so that the walking movement trajectory is approximately a horizontal straight line.

[0047] Example 3: Figure 9 , Figure 10 Front-back two-layer adjacent air cushion group shoes. Each layer is provided with more than one air cushion. The air cushions are adjacent and connected to each other. Each air cushion is provided with an inflation nozzle 12. Use an air pump to inflate each air cushion, and adjust the air pressure in each air cushion so that the walking movement trajectory is close to a horizontal straight line.

[0048] Example 4: Figure 11 , Figure 12 Front-back two-layer adjacent air cushion group shoes and schematic diagram of the compression deformation L of the air cushion. Each layer is provided with more than one elastic air cushion. An interconnected air passage 13 and an inflation nozzle 12 are provided between the air cushions. Use an air pump to inflate the air cushions, and adjust the pressure in the air cushions so that the walking movement trajectory is basically on a horizontal straight line.

[0049] Example 5: Figure 13 , Figure 14Double-layer air cushion group shoes, with more than one elastic air cushion on each layer. An interconnected air passage 13, an air inlet valve 14 and an air outlet valve 15 are provided between the air cushions. By adjusting the air volume of the air inlet valve and the air outlet valve, when the stepping foot lands, the air in the air cushion is compressed by the body weight and the air outlet volume is regulated by the air outlet valve 15 to return to the atmosphere, so that the walking movement trajectory is close to a horizontal straight line. When the foot is lifted again, the air cushion inhales air through the regulation of the air inlet valve.

[0050] Embodiment Six: Figure 15 、 Figure 16 A shoes with three-layer air cushion group in the front two and the back. There is more than one elastic air cushion on each layer. An interconnected air passage 13 and an inflation nozzle 12 are provided between the air cushions. The air cushions of the left and right shoes are connected by an interconnected air hose 16. Inflate the air cushions with an air pump, adjust the air pressure, and then you can walk. When the left foot steps and lands, the air in the air cushion under the shoe is compressed and transmitted through the hose 16 to the air cushion under the right foot. The air cushion under the right shoe is pressurized to boost the sole to bounce off the ground, so that the walking movement trajectory basically maintains a horizontal straight-line movement.

[0051] The above elastic pads of the shoes of the present invention can be continuously stacked and added to form shoes with more than three layers of elastic pads; the elastic pads are divided into elastic foam pads and elastic inflatable pads; or it can be a hybrid elastic pad shoe with a foam pad on the upper layer and an inflatable pad on the lower layer. The elastic pad is an air cushion, that is, a rubber air elastic pad and air cushions such as sports and toy balls; the elastic pad is a foam pad, which is an elastic foam material for shoes such as EVA, MD and ETPU and other shoe-making elastic materials. In addition, for the inflatable pad shoes of the elastic pad, the air in the air cushion can be released according to needs, and the air inlet and outlet nozzles (valves) are closed, and then it can be used as an ordinary soft-soled shoe.

[0052] The above elastic pads are set to have a compression deformation of 1 to 18 cm and an elastic force of 12 to 200 kg. Because this shoe is not only used for walking, but also suitable for running, long jump and high jump. Therefore, the compression deformation of the elastic pad should be much larger than the height difference of the walking wave trajectory, and the elastic force of the elastic pad should also be greater than the multiple of the body weight of the walker. This setting not only ensures that adults with a large body weight can walk, but also is suitable for children and teenagers with a body weight of 12 kg and a walking wave trajectory height difference of 1 cm for fun. For the convenience of teenagers to adjust the elastic force, holes can also be provided on the side of the elastic foam pad on the sole for inlaying elastic foam rods.

[0053] The present invention is not limited to the above embodiments. Simple replacements based on the above embodiments without creative labor belong to the scope of the rights of the present invention.
