Description

Negative heel with special sole pattern

The present invention relates to a heel shoe having a special sole pattern, and more particularly to a heel shoe having a forward dentate structure.

The existing sole patterns can be roughly classified into three types, a columnar pattern whose edges are perpendicular to the surface of the sole, a trapezoidal or triangular pattern whose upper portion of the edge is gradually reduced, and a dentate pattern whose edges are generally inclined rearward. These patterns are aimed at shoes with flats and flat shoes, which have a positive meaning for anti-slip, but for negative heels, different designs are needed, because the mechanical state of the heel and the impact on the human body are related to the existing footwear products. Different, so special design is also needed.

The present invention is an improvement to the sole position of the international application PCT/CN99/00134 to increase safety and functionality. For the convenience of description, the sole part of the shoe is divided into seven parallel sections according to the degree of weight bearing. The proportions of the front and back lengths of the sections and the length of the front and rear of the soles are as follows: front end, 12 %; palm front, 12%; forefoot, 16%; palm, 10%; waist, 25%; hind paw, 13% and back, 12%.

In the description of this specification, the following terms of the international application PCT/CN99/00134 are also used:

The term "average weight of the forefoot" refers to the upper surface of the forefoot section of the sole when the shoe is placed on a level ground (ie, the contact surface with the foot, the sock or the insole when worn, and the bottom of the interior of the shoe) on average per square The average number of ground heights in millimeters for a centimeter of 1.5 kilograms;

The term "average load-bearing height at the rear end" refers to the upper surface of the rear end section of the sole when the shoe is placed on a horizontal floor (ie, the contact surface with the foot, the sock or the insole when worn, and the bottom surface of the interior of the shoe) on average per square The average number of heights from the ground in millimeters with a weight of 3 kg;

The inner and outer sides of the forefoot refer to the vertical bisector of the dividing line between the forefoot and the palm of the hand as the left and right sides of the boundary;

The inner side of the waist guard refers to the left and right sides divided by the vertical bisector of the boundary line between the palm front and the waist stop;

The inner side of the rear end refers to the vertical bisector of the boundary line between the rear end and the back palm as the left and right sides of the boundary;

According to this, the right side of the right foot is the inner side of the outer side, and the left side of the left side is the inner side of the outer side. That is, the side of the thumb of the foot is the inner side, and the side of the fifth finger of the foot is the outer side.

The front half of the sole of the present invention refers to the extension line of the boundary line between the waist and the back of the palm, and divides the bottom of the shoe into two parts, the front part of which is the front part and the rest is the back part. As the high and low shoes in front of the sole, the increase in the height of the front half of the sole also increases the weight of the front half, increases the weight ratio before and after, and the situation is top-heavy. This has an adverse effect on the pace start and gait cycle in sports, mainly influencing the running speed and jumping height. It is understandable as an orthopedic rehabilitation shoe, but it is insufficient if it is used as a sports shoe. The lower the ratio of the weight of the front half to the back half of the sole, the more favorable the sports performance, so as a sports shoe, the weight of the front half of the sole should be reduced as much as possible, or the weight of the rear half of the sole should be increased. The front half of the sole is light and the rear half is heavy. For walking and running, it has an optimal guiding effect on gait and is suitable for sports shoes. The specific method, for the front half of the sole, can reduce the structural volume or reduce the specific gravity of the material. The increase in weight in the rear half of the sole may be to increase the structural volume or increase the specific gravity of the material. This change has extended the application range of front high and low shoes to the field of sports shoes, making greater contributions to human health.

The ratio of the weight of the front half to the back half of the sole is less than 1.65:1, which is suitable for rehabilitation after Achilles tendon rupture; the ratio of the weight of the front half to the back half of the sole is less than 1.6:1, suitable for moderate strain of Achilles tendon. Rehabilitation training for patients; the ratio of the weight of the front half to the back half of the sole is less than 1.55:1, which is suitable for rehabilitation training of patients with mild achilles tendon; the ratio of the weight of the front half to the back half of the sole is less than 1.50:1 It is suitable for static functional exercise of patients with severe flat feet; the ratio of the weight of the front half to the back half of the sole is less than 1.45:1, which is suitable for walking rehabilitation of patients with lumbar disc herniation; the ratio of the weight of the front half to the back half of the sole is lower than 1.4:1, suitable for walking rehabilitation exercise in patients with lumbar disc herniation; the ratio of the weight of the first half to the back half of the sole is less than 1.35:1, suitable for walking rehabilitation exercise for patients with lumbar muscle strain; the first half and the second half of the bottom of the shoe The weight ratio is less than 1.3:1, which is suitable for ordinary people's normal running and daily exercise; the ratio of the weight of the front half to the back half of the sole is less than 1.25:1, suitable for all kinds of ball sports; the first half and the second half of the bottom of the shoe The weight ratio is less than 1.2:1, It is suitable for the rehabilitation of diabetic foot patients.

In the fitness shoe of the present invention, the bottom outer surface area of the front half of the sole is greater than 1 square centimeter, and the bottom outer surface area refers to the contact surface with the ground when the shoe is placed on the horizontal ground, and if there is a stud, the stud tip The area is the calculation standard. The larger the area, the stability of the movement.

In the fitness shoe of the present invention, the splicing seam of the inner material of the shoe is less than or equal to two, so that it is convenient for the diabetic foot patient to use, and for the case of rupture, the number of flat seams is less than one.

In the fitness shoe of the present invention, the outer load-bearing height of the forefoot and/or the rear end is higher than the inner average load-bearing height, which can prevent the foot from being inverted, which is beneficial for correction and formation of a correct gait. The average outer load-bearing height of the forefoot and/or the back end is better than the inner average load-bearing height of 2.5 mm.

In the fitness shoe of the invention, the back tilt angle of the sole is greater than 2 degrees, which is beneficial to the forced center of gravity shifting function and the increase of the exercise intensity; the back tilt angle of the sole is greater than 3.5 degrees, which can improve the sports performance.

In the fitness shoe of the present invention, the average load-bearing height on the inner side of the waist stop is lower than or equal to the average load-bearing height on the outer side of the waist stop, so as to avoid protruding of the part, causing traction on the plantar fascia and damaging the health of the arch.

The fitness shoe of the present invention can also add a sheet-like structure to the inner portion of the back of the shoe, and the sheet-like structure is located in the inner portion of the back of the shoe, facing the inner cavity of the shoe, and the heel or heel of the foot when worn. The socks in the sputum area are in contact. The combination of the sheet structure and the inner lining can be glued or seamed. The sheet structure has an area of more than 3 square centimeters, and may be various shapes such as a circle, an ellipse, a semicircle, a square diamond, etc., and the sheet material may be natural leather, artificial leather or textile, and the thickness of the sheet structure is lower than 2 mm, the function of the sheet structure is to adjust the friction and friction coefficient. It can also be used with different application materials to reduce the friction coefficient of the shoe-like structure. Thus, when used initially, the habit of moving forward will cause the heel to The rear cavity of the shoe moves up and down, which produces a feeling that the shoe does not follow the foot, which hinders walking. When the center of gravity is in the heel area, the feeling of not following the foot disappears, which makes the shoe have a reminding effect on the posture, and is realized at the lowest cost.

The solution of the invention is also improved for the application of shoes for diabetic patients, and an unexpected rehabilitation treatment effect can be obtained. First of all, the stitching seam of the inner material of the shoe is less than or equal to two, one or no better, which can reduce the friction with the skin and avoid damage to the skin and wound.

For the diabetic shoes, the weight distribution of the sole is also pay attention to. The existing negative heel shoes, due to the increase of the thickness of the front half of the sole, the weight of the front half of the sole is large, the walking is the upper part of the instep and the toe is increased, and the friction is also larger. It is also difficult to lift the foot, which is not good for the wound on the instep and the upper part of the toe. To this end, it is necessary to reduce the weight of the front half of the sole, while increasing the weight of the second half, thus forming a lever force, which is more conducive to the forefoot is raised, which is also beneficial to the elderly.

The total weight of a pair of shoes should be less than 1.5 kg, preferably less than 1 kg.

From the front and rear weight distribution of the shoes, the preventive type of products, the weight of the first half of the shoes, the proportion of the total weight of the shoes, less than 60%; the forefoot appears slightly ruptured, the weight of the first half of the shoes, the proportion of the total weight of the shoes, Less than 55%; the forefoot has a moderate rupture, the weight of the first half of the shoe, the proportion of the total weight of the shoe, less than 50%; the forefoot is severely ruptured, the weight of the first half of the shoe, the proportion of the total weight of the shoe , less than 45%; the risk of cutting-off, the weight of the first half of the shoe, the proportion of the total weight of the shoe, less than 40%;

The front and rear weight distribution control of the shoe can be achieved by combining the sole, the front half and the back half of the outsole (outsole) of the shoe (using the middle boundary of the longitudinal length) with different material combinations, and the average specific gravity of the material of the rear half of the outsole is high. The average specific gravity of the outsole material in the first half. For preventive products, the average specific gravity of the material in the second half of the outsole is higher than 5% of the average weight of the outer layer of the first half; the average proportion of the material in the rear half of the outsole is slightly higher than that in the first half. The average specific gravity of the bottom material is 10%; the forefoot is moderately ruptured, the average specific gravity of the material in the second half of the outsole is higher than the average specific gravity of the outer half of the first half; the forefoot is severely ruptured, and the second half of the outsole The average specific gravity of some materials is higher than the average specific gravity of the first half of the outer bottom material by 20%; if there is a risk of cutting off the foot, the average specific gravity of the material in the second half of the outsole is higher than the average specific gravity of the outer half of the first half;

From the weight of the sole, the front half of the outsole (outsole) of the shoe (in the middle of the longitudinal length) accounted for less than 60% of the total weight; the preventive product, less than 55%; the forefoot showed a slight rupture, Less than 50%; moderate to rupture of the forefoot, less than 45%; severe rupture of the forefoot, less than 40%; risk of cut-off, less than 45%.

The invention has the advantages of increasing the role of reminding, being more functional and more suitable for use by diabetics. Compared with the existing diabetes shoes, the ability to stretch the Achilles tendon can avoid the Achilles tendon surgery, and the protection and rehabilitation effect is better. And the front high and low sole can prevent the foreign body in the shoe from damage to the forefoot. At the same time, the technology is also extended to the field of sports shoes to play a greater role.
