Description

Technical Field

[0001] The invention relates to the technical field of footwear, in particular to a sole and a shoe suitable for dragging. Background Art

[0002] The process of walking is to move forward by alternately lifting, stepping, and lowering the two feet. However, in some people, the height of their feet (single or double feet) is not enough, resulting in the original forward step becoming the forefoot dragging on the ground. There are many reasons for this way of walking, including bad habits, and more importantly, it is caused by lower limb weakness, which is often pathological. The bad walking posture caused by bad habits can be improved through training or correction, while for pathological ones, it needs to be alleviated through treatment, and generally exists for a long time or lasts for a long time, and specially designed shoes may be needed to improve the difficulty of walking. This difficulty is reflected in the fact that ordinary shoes usually do not consider the dragging walking method. Therefore, during the dragging process, the ordinary soles come into contact with the ground and slide relative to the ground during the dragging process, and the sliding friction is very large. And this part of the population is often concentrated in the elderly and people with partial functional loss due to illness. They are unable to resist the large friction force during walking, which further aggravates the difficulty of walking and is prone to falling. At the same time, it will also cause abnormal wear on the soles, increasing the economic burden of vulnerable groups. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the present invention is to provide a sole that reduces the friction between the sole and the shoe when dragging, by arranging a sliding part and an adjusting part at the forefoot position of the sole, and by adjusting the relative protrusion degree of the adjusting part and the sliding part, the anti-skid part protrudes to provide sufficient friction between the ground when stepping on, and the sliding part protrudes to reduce friction when dragging. The present invention also aims to provide a shoe comprising the above sole.

[0004] To this end, the present invention provides a sole suitable for dragging, including a forefoot portion, wherein the forefoot portion is provided with an anti-skid portion, the forefoot portion further includes a sliding portion protruding outwardly relative to the anti-skid portion, the forefoot portion further includes a sliding portion protruding outwardly relative to the anti-skid portion, the sliding portion has elastic inward collapse and elastic recovery capabilities after being subjected to pressure, and the anti-skid portion touches the ground after the elastic inward collapse of the sliding portion exceeds a set value.

[0013] The present invention also includes a pair of shoes suitable for dragging, comprising the above-mentioned sole suitable for dragging.

[0014] The beneficial technical effects of the present invention are:

[0015] (1) The present invention provides a shoe sole suitable for dragging, comprising an anti-skid portion, a sliding portion and an adjusting portion, which cooperate with each other. This cooperation is related to the gait of the walking process. Specifically, the walking process is divided into stepping on the ground (support) and striding (dragging). In the stepping on the ground stage, the sole supports the weight of the body, and the deformation of the adjusting portion makes the anti-skid portion the main force-bearing component and provides sufficient friction for support. In the striding stage, the weight of the body acts on the other foot, and the sole corresponding to the striding is subjected to less pressure. The sliding portion protrudes from the surface of the sole, and the sliding portion is made of hard material, so the friction is small and it is convenient for walking.

[0016] (2) In a specific embodiment of the present invention, the sliding portion is configured to be a long strip along the length direction of the sole, which is beneficial to reducing the friction between the sliding portion and the ground during dragging. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Reference Figures 1 to 7 As shown, a sole suitable for dragging of the present invention comprises a forefoot portion 2, wherein the forefoot portion 2 is provided with an anti-skid portion 7, and the forefoot portion 2 further comprises a sliding portion 6 protruding toward the bottom surface of the sole relative to the anti-skid portion 7, and the sliding portion has elastic inward and elastic recovery capabilities after being subjected to pressure, and the anti-skid portion touches the ground after the elastic inward depression of the sliding portion exceeds a set value, so that the corresponding sliding portion 6 of the sole protrudes from the anti-skid portion 7 during the dragging process, and the anti-skid portion 7 contacts the ground when the sole 1 supports the foot. The sole 1 comprises a forefoot portion 2 and a heel portion 3, and the heel portion 3 can be provided with anti-skid patterns in a conventional manner. In this embodiment, two groups of left and right anti-skid patterns including transverse and longitudinal staggered patterns are provided at the heel portion and the arch position, and a groove is provided at the rear of the heel portion, in which a patch can be fixed, and anti-skid is achieved at the heel portion by the transverse anti-skid patterns provided on the patch 8. Of course, the patch can also achieve other functions such as wear resistance by adopting wear-resistant materials. The structure of the forefoot portion 2, refer to Figures 1 to 3 as well as Figure 5The specific embodiment 1 of the present invention is shown, which includes a sliding part 6, the sliding part 6 is made of hard material, the adjustment part includes an elastic body 9, the elastic body 9 is made of elastic material, the sliding part 6 is fixed on the elastic body, and the other side of the elastic body 9 is fixed to the sole body. The elastic body is set at the forefoot part of the sole 1 and the anti-skid part 7 is set at other positions other than the sliding part. The shape and setting method of the anti-skid part 7 can adopt the existing technology. This embodiment is mainly realized by concave and convex anti-skid patterns. Due to the difference in body weight, the elastomer 9 can be made of highly elastic material, which is deformed enough under a large pressure to make the anti-skid part 7 contact with the ground and make the anti-skid part 7 the main force-bearing part. The large pressure can be a pressure less than the corresponding pressure of the general weight of the product audience, such as an average adult weighing 50kg, and half of the corresponding pressure value is used. When dragging, due to the action of the lower limbs, the sole 1 is subjected to a smaller force from the foot. The elastomer 9 ensures that the sliding portion 6 protrudes from the sole 1 or the anti-slip portion 7 under a smaller force. This smaller force can be determined or set according to actual conditions. For example, the force can be set to a certain value. According to experiments, anti-slip is achieved when the force exceeds 300 Newtons.

[0027] In the above embodiment 1, referring to Figures 1 to 3 As shown, the sliding part 6 is in the shape of a sheet, i.e., it is thin, and is arranged in a strip shape in the length direction of the sole 1, i.e., it is small in width. The strip-shaped sliding part 6 reduces the width, which can reduce the contact area and reduce the friction when dragging. The sliding part 6 is arranged on both sides of the forefoot part 2, which can avoid abnormal postures and is conducive to maintaining balance. For example, when the sole 1 tilts, the anti-skid part 7 or other parts of the non-skid part contact the ground, which accidentally increases the friction. The sliding part can also increase the area in the middle of the shoe for anti-skid.

[0028] In the above embodiment 1, referring to Figures 1 to 3 As shown, the thickness of the elastic body 9 is greater than the thickness of the sliding portion 6. By increasing the thickness of the elastic body 9, the protrusion between the sliding portion 6 and the anti-skid portion 7 is increased to avoid the contact between the anti-skid portion 7 and the ground during dragging.

[0029] In the above embodiment 1, referring to Figure 6 As shown, the surface of the sliding portion can be provided with one-way anti-skid patterns, such as herringbone anti-skid patterns, or other existing one-way anti-skid patterns, to achieve a smaller friction coefficient when dragging forward and a larger friction coefficient when moving backward. Similarly, lateral anti-skid patterns can also be provided simultaneously or separately.

[0030] In the above-mentioned embodiment 1, the anti-slip portion 7 is arranged around the sliding portion 6, including a transverse portion 701 and a longitudinal portion 702. The anti-slip portion 7 is in the shape of an I-beam, a S-beam, a W-beam, a F-beam, etc. as a whole. Of course, it can also be in other shapes. In this embodiment, the S-beam shape is adopted. The front part of the anti-slip portion 7 covers the front side of the sole 1, that is, the part of the sole 1 in front of the sliding portion 6. The rear side of the anti-slip portion 7 is arranged behind the sliding portion 6, and is flush with the surface of the sole 1 and extends to the edges on both sides of the sole 1. The elastomer 9 on the lower side of the sliding portion 6 is arranged to be adjacent to or in contact with the edge of the anti-slip portion 7.

[0031] In the above-mentioned embodiment 1, a pad 5 is included, and the pad 5 is suitable for being fixed on the forefoot position of the sole body, extending from one side of the sole body to the other side. The pad 5 is in a U-shape as a whole, and the two sides of the U-shape correspond to the two sides of the sole 1 respectively. The pad 5 can be an elastic body 9 as a whole, or an elastic body 9 can be provided on both sides of the pad 5 to form two arms, and the middle part of the pad 5 is concave inward, that is, lower than the two arms, to form a groove suitable for fixing the anti-skid part 7. In this embodiment, the pad 5, the sliding part 6 and the anti-skid part 7 can be produced, processed and formed separately, and then assembled at a later stage, or the sliding part 6 and the anti-skid part 7 can be processed together to form an integral pad, and then fixed to the sole body.

[0032] In the above-mentioned embodiment 1, the forefoot position of the sole body is formed with a mounting area 4 for mounting the above-mentioned pad 5, and the surfaces corresponding to the mounting area 4 and the pad 5 can be formed into a plane, an arc surface, a wave shape or other shapes, and the surface of the mounting area 4 is lower than the surface of the heel position of the sole body, and the anti-skid part corresponds to the height of the heel position of the sole body after installation. Further, a step surface 401 is formed between the mounting area 4 and the heel position of the sole body and the front part of the forefoot part 2, and the step surface 401 is used to mount the transverse part 701 of the anti-skid part 7, and the height of the step surface 401 can correspond to or be flush with the height of the middle part of the pad 5.

[0033] Reference Figure 4 As shown, Example 2 of the present invention is basically the same as Example 1, the difference lies in the position and shape of the sliding portion. A plurality of protruding sliding portions 6 can be separately arranged at the forefoot position of the sole 1, and an elastic body 9 is arranged under the sliding portion 6, which can also achieve a similar effect. The number and position distribution of the sliding portions 6 can be selected as needed.

[0034] Reference Figure 5 As shown, Example 3 of the present invention is basically the same as Example 1, and the difference lies in the position and shape of the sliding portion. In Example 3, the sliding portion is set in the middle of the forefoot part of the sole, extending from the toe position to the arch of the foot, and both sides are anti-slip parts. The advantage is that the anti-slip effect can be achieved when tilted to both sides, and the sliding area can be set according to the walking action.

[0035] The present invention also discloses a pair of shoes suitable for towing, which adopts the above-mentioned sole 1 suitable for towing.
