Description

Technical Field

[0001] This invention relates to the sole of a multi-braking walking gliding shoe and the gliding shoe itself, belonging to the field of footwear materials. Background Technology

[0002] Shoes are an essential daily necessity and can be categorized into everyday protective walking shoes, roller skates with gliding functions such as rollers or ice skates, and special shoes used under special conditions.

[0003] For example, Chinese utility model patent CN2636923Y, entitled "One-Way Cycling Shoe," discloses a one-way cycling shoe with pulleys mounted on a support frame under the shoe plate and a brake installed at the rear of the shoe plate. Another example is Chinese utility model patent 221332709U, entitled "A Braking Mechanism for a Skating Shoe," which discloses a braking mechanism for a skating shoe with a brake component at the front of the sole. Existing skating shoes of this type brake rely on the friction between the brake at the front or rear of the sole and the ground to achieve braking. However, during braking, the wheels still tend to roll forward, and the overall braking effect of the sole is still unsatisfactory.

[0004] Based on the above issues, the applicant conducted research on these issues and thus this case came into being. Summary of the Invention

[0005] The purpose of this invention is to provide a skating shoe sole with a simple structure and better braking effect. Another purpose of this invention is to propose a skating shoe using this sole.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-braking walking and gliding shoe sole includes a sole body, a roller skate mounted on the sole body, and a braking mechanism for braking the roller skate. The braking mechanism includes at least a first braking part that can act on the roller skate and prevent the roller skate from rotating forward, and a second braking part that can act synchronously on the ground and increase the sliding resistance of the sole body.

[0007] In a preferred embodiment of the present invention, the braking mechanism is a brake wheel that rotates in one direction or in both directions. The brake wheel is in contact with the roller skate body and is rotatably mounted on the sole body. The lowest point of the brake wheel's surface is higher than the lowest point of the roller skate body's surface. The contact position between the brake wheel and the roller skate body is the first braking part, and the contact position between the brake wheel and the ground is the second braking part.

[0008] 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 part, and the position corresponding to the heel is designated as the heel part. The roller skate and the brake wheel are disposed in the heel part, or the roller skate and the brake wheel are disposed in the forefoot part, or the roller skate and the brake wheel are disposed in both the forefoot part and the heel part.

[0009] As a preferred embodiment of the present invention, the sole body is provided with a plurality of axle grooves, the axle grooves are in the shape of "Ω", the plurality of axle grooves are arranged along the length direction of the sole body, the axle grooves are opened from the lower surface of the sole body upward, the axle grooves pass through from the left side to the right side of the sole body, and the axle of the brake wheel or the axle of the roller skate is detachably engaged in the axle grooves.

[0010] As a preferred embodiment of the present invention, a slot is provided on the side of the sole body, the slot extending from one end to the other in the front-rear direction of the sole body, the axle of the brake wheel is detachably inserted into the slot and can move back and forth in the slot, and a tension spring is also included, one end of the tension spring is connected to the axle of the brake wheel, and the other end is connected to the axle of the roller skate or to the sole body.

[0011] In a preferred embodiment of the present invention, one of the roller skates and one of the brake wheels constitute a set of walking wheels, and there are at least two sets of walking wheels, which are respectively arranged on the left and right sides of the sole body.

[0012] In a preferred embodiment of the present invention, the sole body includes at least a hard lower layer, the roller skate and the brake wheel are disposed in the hard lower layer, the sole body also includes a soft upper layer, the soft upper layer is laminated on the hard lower layer, a return spring is provided between the front part of the soft upper layer and the front part of the hard lower layer, a braking gap is formed between the soft upper layer and the wheel surface of the roller skate or the wheel surface of the brake wheel, and a brake pad is provided on the soft upper layer corresponding to the brake wheel or the roller skate.

[0013] In a preferred embodiment of the present invention, when the brake wheel is disposed on the heel, it is a one-way wheel that fits the sliding body and can rotate backward, and the sliding body is a two-way wheel disposed on the front end of the brake wheel; when the brake wheel is disposed on the forefoot, it is a one-way wheel that fits the sliding body and can rotate backward, and the sliding body is a two-way wheel disposed on the rear end of the brake wheel.

[0014] In a preferred embodiment of the present invention, the braking mechanism includes a brake rod hinged to the sole body, a first braking part disposed at one end of the brake rod along the length direction, a second braking part disposed at the other end of the brake rod along the length direction, a top compression spring disposed on the sole body to separate the first braking part from the roller skate, and the second braking part being located between the lower surface of the sole body and the lowest point of the wheel surface of the roller skate.

[0015] In a preferred embodiment of the present invention, the sole body includes a hard lower layer and a soft upper layer disposed on the hard lower layer. The roller skate is disposed in the lower layer. The end of the upper layer extends downward and forward or downward and backward to form a braking zone. A braking block is provided in the braking zone corresponding to the roller skate. The braking block is separately disposed from the roller skate. A braking gap is formed between the braking block and the wheel surface of the roller skate. The braking block forms a first braking part corresponding to the wheel surface of the roller skate that can fit against the wheel surface of the roller skate. The braking block forms a second braking part corresponding to the ground that can press against the ground. The lowest point of the braking zone is higher than the lowest point of the wheel surface of the roller skate.

[0016] The present invention also proposes a gliding shoe, comprising a sole and an upper or strap attached to the sole, wherein the sole is the aforementioned sole type.

[0017] By adopting the technical solution of this invention, during braking, the first braking part acts on the roller skate to directly prevent it from rolling forward, while the second braking part acts on the ground to prevent the entire sole from moving forward. Through multiple braking mechanisms, the braking effect is improved. This invention also proposes braking mechanisms with various structures. In particular, when the braking mechanism uses a unidirectional rotating brake wheel, during walking, the brake wheel is in contact with the roller skate, rotating as the roller skate rolls forward, while simultaneously limiting the roller skate's backward rolling, preventing the entire sole from slipping backward. This allows the sole to be used as a regular walking shoe. During braking, while the brake wheel contacts the ground for friction braking, it also brakes the roller skate through contact with the roller skate. The entire braking structure is simple and has a good braking effect. Preferably, this invention provides an axle groove, in which the axle of the roller skate or the brake wheel is detachably installed. This allows for the addition or removal of roller skates as needed, meeting the requirements of different users. Preferably, the present invention provides a slot at the rear heel, into which the axle of the brake wheel is directly inserted, and the axle of the brake wheel is pulled by a tension spring, so that the brake wheel can be tightly attached to the wheel surface of the wheel slide body. In addition, the brake wheel can be prevented from accidentally slipping off by providing a limiting pin and a limiting sleeve. Attached Figure Description

[0037] To better understand the technical solution of the present invention, a more detailed description is provided below with reference to the embodiments.

[0038] Reference Figures 1 to 18 Using the direction of the toes corresponding to the sole body 10 as "forward" and the direction of the heel corresponding to "backward" as "rear," the multi-braking walking and gliding shoe sole includes a sole body 10, a roller skate 20 mounted on the sole body 10, and a braking mechanism for braking the roller skate 20. The braking mechanism includes at least a first braking part 31 that acts on the roller skate 20 and prevents it from rotating forward, and a second braking part 32 that acts simultaneously on the ground and increases the sliding resistance of the sole body 10. In this invention, during braking, the first braking part 31 acts on the roller skate 20, preventing it from rolling forward, while the second braking part 32 acts on the ground (the surface on which the roller skate 20 slides, such as brick surfaces, cement roads, etc., collectively referred to as the ground), increasing the frictional resistance between the entire sole body 10 and the ground.

[0039] In a preferred embodiment of the present invention, the braking mechanism is a brake wheel 30 that rotates in one direction or in both directions. Preferably, a brake wheel that rotates in one direction is selected, as it can only rotate in one direction. The unidirectional brake wheel 30 has been disclosed in existing roller skates, utilizing a one-way bearing to achieve unidirectional rotation. The specific structure will not be described in detail here. In this invention, the brake wheel 30 is in contact with the roller skate body 20 and is rotatably mounted on the sole body 10. When the roller skate body 20 rolls forward, the brake wheel 30 rolls backward accordingly. The lowest point of the brake wheel 30's surface is higher than the lowest point of the roller skate body 20's surface. That is, during walking, the present invention achieves gliding by the roller skate body 20 contacting the ground, while the brake wheel 30 does not contact the ground. When braking is needed, the sole body 10 is controlled. Taking the brake wheel 30 located at the heel as an example... Figure 1 As shown, specifically, the front end of the sole body 10 is raised while the rear end touches the ground, causing the brake wheel 30 to contact the ground. At this time, since the brake wheel 30 cannot roll forward, it prevents the entire sole from sliding forward. In this embodiment, the first braking part 31 and the second braking part 32 are dynamic parts on the brake wheel 30. As the brake wheel 30 rotates, the positions of the first braking part 31 and the second braking part 32 continuously change. The part of the brake wheel 30 that contacts the roller skate body 20 is called the first braking part, and the part that contacts the ground is called the second braking part.

[0040] In a preferred embodiment of the present invention, the sole body 10 is designated as a forefoot portion corresponding to the front of the foot and a heel portion corresponding to the heel. The roller skate 20 and the brake wheel 30 are located in the heel portion, or the roller skate 20 and the brake wheel 30 are located in the forefoot portion, or both the forefoot portion and the heel portion are equipped with the roller skate 20 and the brake wheel 30. Taking the roller skate 20 and the brake wheel 30 located in the heel portion as an example, the brake wheel 30 is in contact with the roller skate 20 and is located behind the roller skate 20. When braking, the forefoot portion is lifted, causing the sole body 10 to rotate around the axis of the roller skate 20 with the roller skate 20 as the fulcrum, thereby causing the brake wheel 30 to contact the ground and perform braking.

[0041] Reference Figure 8In one embodiment of the present invention, the brake wheel 30 is mounted on the sole body 10 via a first wheel axle 37. The first wheel axle 37 is arranged in the left-right direction. A first axle seat 33 is provided on the sole body 10. The first wheel axle 37 is adjustable in the first axle seat 33. Specifically, the first axle seat 33 is provided with an adjustment groove 34. The first wheel axle 37 is placed in the adjustment groove 34. The first axle seat 33 is provided with a tension spring 36 and a tightening screw 35 acting on the first wheel axle 37. The tightening screw 35 is threaded in the first axle seat 33. The tension spring 36 is located between the first wheel axle 37 and the tightening screw 35. By adjusting the tightening screw 35, the wheel surface of the brake wheel 30 can be made to adhere to the roller skate body 20 with a suitable force.

[0042] In this invention, the number of roller skates 20 can be two, four, six or eight, and they are arranged along the front and back direction of the sole body 10. In this invention, the roller skates 20 can be unidirectional wheels (which can only rotate in one direction) or bidirectional wheels (which can rotate forward or backward).

[0043] As a preferred embodiment of the present invention, one of the roller skates 20 and one of the brake wheels 30 constitute a set of walking wheels, and there are at least two sets of walking wheels. The two sets of walking wheels are respectively arranged on the left and right sides of the sole body, so that the walking of the sole is more stable.

[0044] In a preferred embodiment of the present invention, the sole body 10 includes at least a rigid lower layer 11, in which the roller skate 20 and brake wheel 30 are both mounted. The rigid lower layer 11 can be made of materials commonly used in shoe soles, such as PA66. To enable the sole body 10 to bend energy-absorbingly according to the usage scenario, a bending groove 21 is provided in the rigid lower layer 11 to assist bending at a predetermined position, or the rigid lower layer 11 can be divided into multiple segments, with bending grooves 21 formed between adjacent segments. The sole body 10 also includes a soft upper layer 12, which is laminated onto the rigid lower layer 11. The soft upper layer 12 can be made of materials such as EVA.

[0045] Reference Figure 2In a preferred embodiment of the present invention, a return spring 15 is provided between the front portion of the soft upper layer 12 and the front portion of the hard lower layer 11. A braking gap 13 is formed between the soft upper layer 12 and the wheel surface of the roller body 20 or the wheel surface of the brake wheel 30, making it easier for the soft upper layer 12 to deform relative to the hard lower layer 11. A brake pad 14 is provided on the soft upper layer 12 corresponding to the brake wheel 30 or the roller body 20. By providing the return spring 15, the brake pad 14 of the soft upper layer 12 is separated from the brake wheel 30 or the roller body 20. When the front portion of the soft upper layer 12 is pressed with a toe, the soft upper layer 12 compresses the return spring 15, causing the brake pad 14 to press against the brake wheel 30 or the roller body 20, thereby achieving braking. In the present invention, the brake pad 14 can be made of the same material as the soft upper layer 12 and integrally formed, or it can be made of a different material and fixed to the soft upper layer.

[0046] Reference Figure 7 In a preferred embodiment of the present invention, the sole body 10 forms a first extension 16 and a second extension 17 on both sides (left and right sides) of the braking gap 13. The first extension 16 corresponds to one set of wheels, and the second extension 17 corresponds to another set of wheels. Brake pads 14 are correspondingly disposed on the first extension 16 and the second extension 17. In this case, by pressing the front end of the sole body 10 down into the braking gap 13, the brake pads 14 brake the wheels, thereby enabling the present invention to achieve progressive braking or intermittent braking depending on the application.

[0047] Reference Figure 13 In another embodiment of the invention, the rigid lower layer 11 extends outward on both sides to form support areas 116. The roller skate 20 and brake wheel 30 are installed in these support areas 116, making the area where the fulcrum of the roller skate 20 is located larger, and making the entire walking and gliding shoe more stable for walking and gliding. A notch is formed in the rigid lower layer 11 corresponding to the position of the soft upper layer 12, thereby allowing the soft upper layer at that position to bend better and achieve braking. Referring again... Figure 18The present invention can integrally form a first brake block 117 and a second brake block 118 on the side wall of the soft upper layer 12 corresponding to the roller body 20 and the brake wheel 30, respectively. When the front end of the soft upper layer 12 is pressed down, the first brake block 117 can brake the brake wheel 30, and the second brake block 118 can brake the roller body 20, thereby further improving the braking effect. The present invention can also provide an auxiliary deformation groove 22 at the heel of the sole body 10, with a hard lower layer 11 corresponding to the auxiliary deformation groove 22. A support spring 23 is provided on the hard lower layer 11 corresponding to the auxiliary deformation groove 22, and a third braking block 119 for braking the roller skate 20 is provided on the soft upper layer 12. When a certain force is applied to press down the heel, the soft upper layer 12 can compress the support spring 23, so that the third braking block 119 presses against the roller skate 20, thereby braking the roller skate 20. After the force applied to the heel weakens, the heel can return to its original position under the action of the support spring 23.

[0048] like Figure 3 As shown, in another preferred embodiment of the present invention, the braking mechanism includes a brake rod 70 hinged to the sole body 10, specifically hinged via a hinge shaft 72, which is arranged in a horizontal direction. The first braking part 31 is disposed at one end of the brake rod 70 along the length direction, and the second braking part 32 is disposed at the other end of the brake rod 70 along the length direction. A top-compression spring 71 is provided on the sole body 10 to separate the first braking part 31 from the roller skate 20. Under the action of the top-compression spring 71, the first braking part 31 is temporarily separated from the roller skate 20 to ensure the normal gliding of the roller skate 20. The second braking part 32 is located between the lower surface of the sole body 10 and the lowest point of the wheel surface of the roller skate 20. In this embodiment, the brake lever 70 is located on the rear side of the roller skate 20. During use, the forefoot is lifted upwards, i.e., the heel is pressed backwards, causing the second braking part 32 to contact the ground and rotate around the hinge axis 72 until the first braking part 31 presses against the wheel surface of the roller skate 20, thus achieving wheel surface braking of the roller skate 20. (Refer to...) Figure 4 Preferably, in addition to brake levers 70 respectively provided on the corresponding left and right sides of the roller body 20, a middle brake lever 73 is also provided between the two brake levers 70. The middle brake lever 73 is hinged on the hinge shaft 72. A compression spring can be provided between the middle brake lever 73 and the sole body 10. At this time, the middle brake lever 73 can touch the ground first to brake, which plays a buffering role, and the brake levers 70 on both sides will then touch the ground to brake.

[0049] Reference Figure 5In a preferred embodiment of the present invention, the braking mechanism includes a sliding block 80 slidably disposed on the sole body 10. The first braking part 31 is a first brake pad disposed on the sliding block 80, and the second braking part 32 is a second brake pad disposed on the sliding block 80. In the embodiment, the first brake pad and the second brake pad are disposed on the front and rear sides of the roller skate body 20, respectively. An elastic mechanism is provided on the sole body to separate the sliding block 80 from the roller skate body 20. The elastic mechanism can be, for example, a screw and a compression spring, which applies a force to the sliding block 80, causing the first brake pad to temporarily separate from the roller skate body 20. When braking is required, the forefoot is lifted upward, thereby causing the heel to press backward, and the second braking part 32 contacts the ground. At this time, the sole body 10 slides forward a short distance relative to the sliding block 80, thereby causing the roller skate body 20 to contact the first braking part 31, thus achieving wheel braking. To better guide the sliding block 80 to slide, a corresponding guide groove 81 can be set on the sliding block 80, and a guide rail 111 that cooperates with the guide groove 81 can be set on the sole body 10.

[0050] Reference Figure 9 In a preferred embodiment of the present invention, the sole body 10 is provided with a plurality of axle grooves 112 for securing the axle (the axle of the brake wheel 30, the roller skate 20, or the brake wheel). In the embodiment, the axle grooves 112 are Ω-shaped, and the plurality of axle grooves 112 are arranged along the length direction of the sole body 10. The axle grooves 112 open upward from the lower surface of the sole body 10 and extend from the left side to the right side of the sole body 10. The axle is detachably secured in the axle groove 112. Figure 9 The image shows 6 axle slots 112. Of course, more axle slots 112 can be set, and users can add or remove the required number of axles as needed.

[0051] Reference Figures 10 to 12 , Figure 13 , Figure 14 , Figure 15 , Figure 17 In a preferred embodiment of the present invention, a groove 113 is provided on the side of the sole body 10. The groove 113 extends from one end of the sole body 10 in the front-rear direction to the other end. The axle of the brake wheel 30 is detachably inserted into the groove 113 and can move back and forth within the groove 113. A tension spring 60 is also included, one end of which is connected to the axle of the brake wheel 30, and the other end is connected to the axle of the roller skate 20 or to the sole body 10. Preferably, a limiting pin 114 or a limiting sleeve 115 is provided at the entrance end of the groove 113. The limiting pin 114 or the limiting sleeve 115 is detachably provided at the entrance position of the groove 113 to facilitate the installation of the axle and prevent accidental slippage of the axle. Figure 17In the middle, the hard lower layer 11 extends obliquely upward at the heel, and a slot 113 is provided at its rear end, through which the axle of the brake wheel 30 is engaged into the hard lower layer 11.

[0052] Reference Figure 16 In this invention, a mounting groove extending upwards is provided at the lower front end of the soft upper layer 12, and the hard lower layer 11 is disposed in the mounting groove. The roller skate 20 and the brake wheel 30 are disposed on the hard lower layer 11. At this time, the lower end of the soft upper layer 12 can be lower than the roller skate 20 and the brake wheel 30. The entire sole is normally used as a flat shoe. When gliding is required, the heel of the sole body is raised, and the forefoot of the sole body is pressed down, so that the roller skate 20 contacts the ground, and gliding is performed using the roller skate 20. In this way, the roller skate 20 can be a two-way wheel, and the brake wheel 30 can be a one-way wheel or a two-way wheel. Corresponding brake pads 14 can be provided on the soft upper layer 12.

[0053] The unidirectional wheel described in this invention refers to a wheel that can only rotate in one direction (e.g., only clockwise or counterclockwise), while the bidirectional wheel refers to a wheel that can rotate both clockwise and counterclockwise.

[0054] Reference Figure 6In a preferred embodiment of the present invention, the sole body includes a hard lower layer 11 and a soft upper layer 12 disposed on the hard lower layer 11. The roller skate 20 is disposed in the lower layer 11, and its arrangement can be as described above in a detachable manner. The end of the upper layer 12 extends downward and forward or downward and backward to form a braking area. The braking area can be formed in the forefoot or heel of the sole body, or both the forefoot and heel can be provided with braking areas. In an embodiment, both the forefoot and heel are provided with braking areas. A braking block 25 is provided in the braking area corresponding to the roller skate 20. In an embodiment, the braking block 25 is integrally formed with the upper layer 12. Braking blocks 25 are provided on both the left and right sides of the sole body. The roller skate 20 preferably extends out of the left and right sides of the sole body, and the braking blocks 25 also extend out from the left and right sides of the sole body respectively. The braking blocks 25 are separately disposed from the roller skate 20, and a braking gap 13 is formed between the braking blocks 25 and the wheel surface of the roller skate 20. In this application, by selecting the hardness of the soft upper layer, the brake block 25 and the roller skate 20 will not adhere to each other during normal wear. By applying a certain force, the braking area can bend towards the braking gap 13, thereby making the brake block 25 adhere to the roller skate 20. Preferably, a bending groove 21 is also provided between the end of the lower layer 11 and the braking area. The bending groove 21 can assist the braking area to deform better. A balance spring 24 can also be provided on the bending groove 21. One end of the balance spring 24 abuts against the lower layer 11, and the other end abuts against the upper layer 12. In the embodiment, the balance spring 24 is arranged in the horizontal direction to better keep the brake block 25 and the roller skate 20 separated. By selecting the elasticity of the balance spring 24, the force required for the upper layer 12 to bend towards the bending groove 21 can be controlled, thereby controlling the braking force of the braking area. The brake block 25 forms a first braking part 31 corresponding to the wheel surface of the roller skate 20, which can fit against the wheel surface of the roller skate 20. In an embodiment, the first braking part 31 can be an arc-shaped surface that fits against the wheel surface of the roller skate 20. The brake block 25 forms a second braking part 32 corresponding to the ground, which can press against the ground. The second braking part 32 is generally a plane or an inclined plane extending upward. The lowest point of the braking area is higher than the lowest point of the wheel surface of the roller skate 20. In an embodiment, the lowest point of the roller skate 20 is slightly lower than the second braking part 32, so that the sole can glide normally. When the sole is used for walking, the left and right feet swing in an arc from front to back. The front or rear end of the sole body can be pressed down slightly so that the second braking part 32 can land naturally and humanely, so as to make walking more stable. In this embodiment, when braking, a certain force is applied to the braking area by the front part of the foot or the heel. The first braking part 31 adheres to the roller skate body 20, thereby preventing the roller skate body 20 from rolling forward. The second braking part 32 acts on the ground to prevent the entire sole body from sliding forward.

[0055] Reference Figure 2The present invention also proposes a gliding shoe, including a sole and an upper or strap 40 connected to the sole. The upper may be made of a material commonly used in sports shoes, and the strap 40 may be a strap 40 used in slippers or sandals. The sole is a sole as described above.

[0056] The scope of protection of this invention is not limited to this embodiment. Any similar modifications made to it are considered to be within the scope of protection of this invention.
