Description

TECHNICAL FIELD

[0001] The present application relates to a general-purpose fast-walking shoe sole, belonging to the technical field of shoes. BACKGROUND

[0002] Shoes are a necessary daily life product for people, which can be divided into daily wear protective shoes, wheel shoes with sliding function such as skates and ice skates, and special shoes used under special conditions, etc. The protective shoes for walking can be divided into many types according to styles, processes and purposes, etc. No matter which type, they all have a common point that the soles are flat structures adapted to the foot plates, and in use, they walk with the wearer's feet. They are different from the wheel shoes with sliding function. The forward moving force of the protective shoes for walking is completely controlled by the wearer's feet, and the wearer can walk stably and controllably. However, due to the stable and controllable protective shoes for walking, they do not have the self-sliding function like the wheel shoes, and cannot provide certain ecological inertia forward moving force for walking, which has the defect of slow walking.

[0003] The traditional wheel shoes have the self-sliding function, but the soles are hard and integrated front and back. The integration will wrap the foot plate, and the front and back palm parts cannot be flexible to each other. The feet need to be "outward eight" to slide, which produces an angle deviation with the forward direction and does useless work. The feet cannot slide in parallel, and when braking, the whole shoe body needs to be tilted and braked hard, which cannot be gradually and humanized. When the ground is not flat, the front, middle and rear wheels cannot contact the ground as much as possible, and the grip is unbalanced. The traditional wheel shoes can only be used as a kind of entertainment sports product, and cannot be widely used in daily life. In the Chinese patent application No. 201180025791.8, the applicant discloses a one-way self-propelled shoe for walking, which comprises a shoe body, the front part of the sole of the shoe body is slightly tilted relative to the back part, the front part of the sole is provided with an open cavity, the cavity is provided with a sliding wheel body which is arranged in the vertical direction of the length of the shoe body, the lowest point of the sliding wheel body is out of the opening of the cavity and is flush with the back part of the sole, and the sliding wheel body is provided with a one-way control member which controls the one-way rotation of the sliding wheel body to drive the forward movement of the sole. The shoe can brake and be suitable for daily wear and use, and has the self-sliding function. However, when sliding and walking, it cannot be gradually braked, and the braking operation is relatively difficult.

[0004] Based on the above problems, the applicant has conducted research, and thus the present case is generated. SUMMARY

[0005] The present application aims to provide a general-purpose fast-walking shoe sole which is suitable for daily wear and use, and has the functions of walking, sliding and gradually humanized braking.

[0045] In order to better understand the technical solutions of the present application, the following will be more detailed in conjunction with examples.

[0046] Referring to Figures 1 to 11A general-purpose walking shoe sole includes a sole body and a roller body 30 disposed at the lower part of the sole body. The roller body 30 includes an axle 32, a one-way bearing mounted on the axle 32, and a wheel 31 sleeved on the one-way bearing. Because a one-way bearing is used, the wheel 31 can only rotate in one direction, so that the sole will not slide backward when used for walking. The rotation direction of the one-way bearing can be, for example, the rotation direction of the one-way bearing mentioned in 201180025791.8 mentioned in the background art, for example, the one-way bearing can only rotate forward and cannot rotate backward.

[0047] In this invention, the sole body comprises an upper layer 10 and a lower layer 20, which are composited together. The lower layer 20 has a higher hardness than the upper layer 10, while the upper layer 10 has a lower hardness and is more flexible, thus improving the comfort of foot contact. In embodiments, the upper layer 10 can be made of commonly used foam materials for shoe soles, such as EVA foam, which is lightweight, soft, and comfortable. The lower layer 20 is made of a harder material, such as plastic, metal, or hard fiber, so that the entire sole body can maintain a relatively stable shape and is not easily deformed when subjected to the force of the roller skating body 30. Those skilled in the art can select the appropriate hardness of the lower layer 20 based on the support requirements of the roller skating body 30.

[0048] In this invention, the wheel body 30 is disposed on the lower body 20, and the front end of the upper body 10 is provided with a braking part 11 that can be bent downwards to brake the wheel body 31. The braking part 11 can directly brake the wheel body 31, or it can indirectly brake the wheel body 31 through other components. When braking directly, the braking part 11 is provided with a friction part 14 that directly contacts the wheel surface of the wheel body 31 (e.g., ...). Figure 11 As shown, the friction part 14 can be made of a relatively wear-resistant material, for example, by attaching a rubber block as the friction part 14. In this invention, the braking part 11 is located in front of the lower body 20. During normal walking or when the sole body is gliding, the lowest point of the braking part 11 will not contact the ground. When gliding braking is required, the front part of the foot, more specifically, the toes, bends downward, thereby causing the braking part 11 to bend downward, so that the braking part 11 brakes the wheel 31.

[0049] In a preferred embodiment of the present invention, a bending space 12 for the movement of the braking part 11 is provided between the braking part 11 and the front end of the lower body 20. Through the size of the bending space 12 and the thickness design of the braking part 11, the braking part 11 can be easily bent after the user applies a certain force. Furthermore, the choice of material for the upper body 10 ensures that the bending service life of the braking part 11 meets usage requirements. Typically, materials such as EVA have a certain degree of resilience, allowing the braking part 11 to automatically spring back after bending. Further, to make the braking part 11 bend and spring back even more easily, the upper body 10 is provided with a deformation joint 13 corresponding to the bending space 12. The deformation joint 13 extends downwards from the upper end of the upper body 10. During braking, the braking part 11 bends at the deformation joint 13, thereby widening the deformation joint 13 from an "I" shape to a "V" shape. Figure 11 The image shows the expansion joint in a V-shape. When the brake is released, the expansion joint 13 contracts. To prevent the brake part 11 from over-opening at the expansion joint 13, limiting bands can be provided on the front and rear sides of the expansion joint 13. One end of the limiting band is fixed to the front end of the expansion joint 13, and the other end is fixed to the rear end of the expansion joint 13. The maximum opening of the expansion joint 13 is the length of the limiting band.

[0050] In a preferred embodiment of the present invention, the position of the sole body corresponding to the front of the foot is designated as the forefoot portion 101, and the position corresponding to the heel is designated as the heel portion 103. The sole body forms an arch portion 102 between the forefoot portion 101 and the heel portion 103. The lower layer 20 is disposed on one or more of the forefoot portion 101, the arch portion 102, and the heel portion 103 of the sole body. That is, the lower layer 20 can be disposed at any position of the forefoot portion 101, the arch portion 102, and the heel portion 103. In an embodiment, the lower layer 20 extends from the heel portion 103 to the forefoot portion 101. In a preferred embodiment of the present invention, the upper body 10 extends from the forefoot portion 101 to the heel portion 103, and the lower body 20 is divided into multiple segments. Preferably, the segments are connected together by stretchable ribs 21, which allows the lower body 20 to bend better at the segmented locations, enabling the sole body to bend better and improving comfort. The ribs 21 also ensure better overall alignment of the upper body 10 and the lower body 20 during assembly, guaranteeing that the forward direction of the wheel 31 is parallel between different segments. To enhance the strength of the lower body 20, crisscrossing reinforcing ribs 22 can be provided on its surface.
