The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] Please refer to Figures 1-4The embodiment of the present invention provides an ice and snow reuse shoe 100, comprising a shoe forebody 110, a shoe back 120, a sole 130, and a sliding assembly 140; the shoe back 120 is folded and connected to the shoe forebody 110; the sole 130 comprises a front portion 131 and a rear portion 132, the front portion 131 is connected to the bottom side of the shoe forebody 110, and the rear portion 132 is connected to the shoe back 120 and is located on the same side of the shoe forebody 110; the sliding assembly 140 comprises a main slider 141 and a stopper 142, the main slider 141 comprises a first arc portion 1413, the second arc portion 1414 and the second arc portion 1415. An arc portion 1413 is arranged near the rear portion 132, and the stopper 142 includes a positioning portion 1421 and an extension frame 1422. The positioning portion 1421 is detachably connected to the connection between the front portion 131 and the rear portion 132, and the extension frame 1422 is connected to the positioning portion 1421 and extends toward the front portion 131 and the rear portion 132 respectively. A tooth notch 14221 is formed at the end of the extension frame 1422, and the extension frame 1422 is adapted to the main slide 141 so that the main slide 141 is connected to the tooth notch 14221 through the first arc portion 1413. In a specific application, the main slider 141 is fixed to the sole 130 by gluing, and the main slider 141 on the side away from the sole 130 is in contact with the ground, wherein the main slider 141 away from the front portion 131 and close to the rear portion 132 gradually transitions toward the sole 130 to form a first arc portion 1413. Since the main slider 141 is connected to the sole 130 at the rear portion 132 to form the first arc portion 1413, the ice and snow reuse shoe 100 can smoothly transition to the rear portion 132 of the sole 130, so that the stopper 142 connected to the rear portion 132 of the sole 130 can smoothly stop on the ground. In this way, on the one hand, the user can adjust the force point at the rear portion 132 of the sole 130 so that the stopper 142 can stop on the ground smoothly. Ice debris produced on the ice surface or snowflakes produced on the snow ground by the component 142 are blocked by the front part 131 (mainly) and the rear part 132 of the sole 130, thereby preventing the ice and snow reuse shoe 100 from accumulating snow or ice during use. On the other hand, the main slider 141 connects the tooth groove 14221 through the first arc portion 1413 to prevent the ice and snow reuse shoe 100 from having a risk of breaking contact. When the ice and snow reuse shoe 100 contacts the ground again after breaking contact, a strong impact will be generated, thereby increasing the risk of braking of the ice and snow reuse shoe 100. Therefore, the risk of impact stopping of the ice and snow reuse shoe 100 can be prevented by connecting the first arc portion 1413 of the main slider 141 to the tooth groove 14221.

[0033] In a possible implementation manner, connecting the positioning portion 1421 at the connection of the front portion 131 and the rear portion 132 can facilitate the positioning and fixing of the stopper 142 in the middle of the sole 130. Since the middle of the sole 130 is recessed inward, the positioning portion 1421 of the stopper 142 is prevented from interfering with the contact of the main slider 141 connected to the sole 130 with the ground. Additionally, the positioning portion 1421 is detachably connected to the sole 130, which can facilitate the replacement of the sliding assembly 140 of different sizes or the replacement of the severely damaged sliding assembly 140. The first arc portion 1413 is arranged close to the rear portion 132, and the stopper 142 is spacedly connected to the rear portion 132 and forms a tooth groove opening 1423. Thus, the main slider 141 is connected to the tooth groove opening 14221 through the first arc portion 1413, and the tooth groove opening 14221 of the extension frame 1422 is used to abut against the ground for braking. In this way, the tooth groove opening 14221 is beneficial to improving the stopping performance of the stopper 142 for ice or snow sliding.

[0034] In a possible implementation manner, the extension frame 1422 includes a first end portion 14222. The rear portion 132 is provided with an obliquely upward first cross-section 1321. The first end portion 14222 is arranged close to the rear portion 132, and the tooth groove opening 14221 formed by the first end portion 14222 is spaced perpendicular to the first cross-section 1321. In specific applications, when the rear portion 132 is provided with the obliquely upward first cross-section 1321, when the stopper 142 brakes, the sole 130 will form a relatively large inclination angle relative to the ground, so that the sole 130 has a larger shielding area for the splashed snowflakes and ice chips, thereby preventing the snow and ice reuse shoe 100 from accumulating snow or ice. However, it should be noted that the angle of the first cross-section 1321 relative to the sole 130 surface should not be too large, which easily causes the snow and ice reuse shoe 100 to require a larger rear inclination angle during braking, resulting in the user falling due to unstable center of gravity. Therefore, the included angle between the first cross-section 1321 and the sole 130 surface is between 3° and 10°. Preferably, the included angle between the first cross-section 1321 and the sole 130 surface is 5°. Additionally, the stopper 142 is perpendicular to the first cross-section 1321, which can enable the stopper 142 to transmit the ground force axially to the rear portion 132 of the sole 130, thereby enhancing the firmness of the connection between the stopper 142 and the rear portion 132 of the sole 130. Among them, the connection between the stopper 142 and the rear portion 132 of the sole 130 is preferably an embedded adhesive bond.

[0035] In a possible implementation, the extension bracket 1422 further includes a second end portion 14223. The front portion 131 is provided with an obliquely upward second cross-section 1311. The alveolar opening 14221 formed by the second end portion 14223 is spaced perpendicular to the second cross-section 1311. In specific applications, when the ice and snow reuse shoe 100 moves forward at a high speed, due to the influence of human inertia, it is relatively difficult to brake through the stopper 142 at the rear portion 132 of the sole 130. Therefore, generally, when the ice and snow reuse shoe 100 is moving at a high speed, first, the alveolar opening 14221 provided at the second end portion 14223 is used for stopping, which can reduce the speed of the ice and snow reuse shoe 100. After the speed of the ice and snow reuse shoe 100 is reduced, the alveolar opening 14221 of the first end portion 14222 is used for braking. In this way, it can be avoided that when the ice and snow reuse shoe 100 moves at a high speed, it is difficult to stop through the stopper 142 due to the influence of human inertia, and it can also avoid the problem of snow or ice accumulation that is likely to occur when the ice and snow reuse shoe 100 directly passes through the alveolar opening 14221 of the second end portion 14223. In addition, it is worth noting that the alveolar opening 14221 of the second end portion 14223 is mainly used to increase the speed of the ice and snow reuse shoe 100, that is, when the ice and snow reuse shoe 100 is stationary or accelerating, the user mainly generates a force on the ground through the alveolar opening 1422 of the second end portion 14223, and the ice and snow reuse shoe 100 is accelerated under the reaction force of the ground.

[0036] In a possible implementation, the main sliding member 141 further includes a second arc portion 1414. The second arc portion 1414 is disposed close to the front portion 131 so that the main sliding member 141 connects to the alveolar opening 14221 of the second end portion 14223 through the second arc portion 1414. In specific applications, in order to prevent the main sliding member 141 from losing contact with the ground when the user operates the stopper 142, which may cause an impact on the ice and snow reuse shoe 100 by the ground, a second arc portion 1414 is provided at the main sliding member 141 close to the front portion 131. Through the transition of the second arc portion 1414, the main sliding member 141 can smoothly connect to the alveolar opening 14221 of the second end portion 14223, preventing danger from occurring when braking through the alveolar opening 14221 of the second end portion 14223.

[0037] In a possible implementation, main sliding members 141 are respectively provided on opposite sides of the sole 130. The main sliding member 141 further includes a sliding body 1415, and the sliding body 1415 is respectively connected to a first arc portion 1413 and a second arc portion 1414. Wherein, the included angle between the inner side of the second arc portion 1414 and the same side of the sliding body 1415 is denoted as a, and satisfies the relational expression: 10° ≤ a ≤ 30°. In specific applications, it is cumbersome and complex to change the movement direction of the ice and snow reusable shoe 100 under normal circumstances, which is not conducive to the operation of the user and is very disadvantageous to beginners. Therefore, this case has been greatly optimized and improved on the basis of the ice and snow reusable shoe 100. First, based on the fact that the ice and snow reusable shoe 100 performs high-speed braking by smoothly transitioning to the force-applying member through the second arc portion 1414. In existing ice skates, the included angle between the inner side of the second arc portion 1414 and this side of the sliding body 1415 is zero degree, which only serves as a transition. However, in this case, the included angle between the inner side of the second arc portion 1414 and the same side of the sliding body 1415 is a, and satisfies the relational expression: 10° ≤ a ≤ 30°. It can be understood that from Figure 4As can be seen, when the user controls the main slider 141 to tilt forward linearly, the main sliders 141 on both sides of the sole 130 are exactly symmetric, with the inner side of the second arc portion 1414 being on the same side as the slider body 1415. When the main sliders 141 on both sides contact the ground simultaneously, the ice and snow multi-purpose shoe 100 continues to move forward until it transitions to the force-applying member for braking. When the right main slider 141 contacts the ground, the moving trajectory of the ice and snow multi-purpose shoe 100 will deflect to the right, thereby achieving a change in the moving direction in a direction slightly to the right forward; when the left main slider 141 contacts the ground, the moving trajectory of the ice and snow multi-purpose shoe 100 will deflect to the left, thereby achieving a change in the moving direction in a direction slightly to the left forward. In the specific operation method, the operator can apply the force point on the right side of the front portion 131 of the sole 130, so that the trajectory of the ice and snow multi-purpose shoe 100 deflects to the right; or the operator can apply the force point on the left side of the front portion 131 of the sole 130, so that the trajectory of the ice and snow multi-purpose shoe 100 deflects to the left, which greatly facilitates the user's control during turning. Additionally, it is worth noting that to prevent non-standard use by beginners, it is not necessary for one side of the main slider 141 to be completely off the ground. Only the forces on the main sliders 141 on both sides need to be proportionally distributed. For the main slider 141 on the side with a larger proportion of the force, the trajectory of the ice and snow multi-purpose shoe 100 will deflect towards that side, which not only facilitates the user's operation but also prevents danger caused by improper user operation, significantly improving the safety of the ice and snow multi-purpose shoe 100. Among them, the included angle a between the inner side of the second arc portion 1414 and the slider body 1415 on the same side is preferably 20°. In specific applications, since the user's foot sizes are different, it is often necessary to adjust the ice and snow multi-purpose shoe 100. When adjusting the size of the ice and snow multi-purpose shoe 100, by adjusting the relative sliding of the first knife slider 1411 and the second slider 1412, the length of the main slider 141 can be adjusted and changed, so that it can be adapted to the size required by the user, thereby maintaining the balanced support of the user during movement.

[0038] In a possible implementation manner, the main slider 141 further includes a first slider body 1411 and a second slider body 1412, and the first slider body 1411 is slidably connected to the second slider body 1412 to adjust the length of the main slider 141. In specific applications, since the user's foot sizes are different, it is often necessary to adjust the ice and snow multi-purpose shoe 100. When adjusting the size of the ice and snow multi-purpose shoe 100, by adjusting the relative sliding of the first knife slider 1411 and the second slider 1412, the length of the main slider 141 can be adjusted and changed, so that it can be adapted to the size required by the user, thereby maintaining the balanced support of the user during movement.

[0039] In a possible implementation, the first sliding body 1411 includes a sliding part 14111 and an extension arm 14112. One side of the sliding part 14111 is fixed to the rear part 132, and the other side of the sliding part 14111 is for contacting the ground. The extension arm 14112 is connected to one end of the sliding part 14111 and extends from the rear part 132 towards the front part 131. The second sliding body 1412 is sleeved and movably arranged on the extension arm 14112. In specific applications, one side of the sliding part 14111 is embedded and glued to the rear part 132 of the sole 130, and the other side of the sliding part 14111 is for contacting the ground. The extension arm 14112 extends from the end of the sliding part 14111 towards the front part 131. A slot hole is formed in the second sliding body 1412, and the extension arm 14112 is inserted into the slot hole, so that the second sliding body 1412 is movably sleeved on the first knife sliding body 1411, thereby facilitating the adjustment of the length of the main sliding part 141 by the first knife sliding body 1411 and the second sliding body 1412 to adapt to the length of the ice and snow reuse shoe 100.

[0040] In a possible implementation, the sliding assembly 140 further includes a fastener 143. At least three first through holes 14101 are formed on one side of the extension arm 14112, and at least three second through holes 14121 corresponding to the first through holes 14101 are formed in the second sliding body 1412. By adjusting the relative positions of the first through holes 14101 and the second through holes 14121, and then the fastener 143 fastens the first through holes 14101 and the second through holes 14121. In specific applications, a plurality of first through holes 14101 are formed in the extension arm 14112, and the number of the first through holes 14101 is not specifically limited; a plurality of second through holes 14121 are formed in the second sliding body 1412, and the number of the second through holes 14121 is not specifically limited. Among them, if the first knife sliding body 1411 and the second sliding body 1412 are in a contracted state, the first through holes 14101 of the first knife sliding body 1411 correspond to the second through holes 14121 of the second sliding body 1412 one by one. If the second sliding body 1412 slides and extends relative to the first knife sliding body 1411, when the first through holes 14101 of the first knife sliding body 1411 are misaligned with the second through holes 14121 of the second sliding body 1412, the first through holes 14101 and the second through holes 14121 can be fastened by the fastener 143 to fix and lock the states of the first knife sliding body 1411 and the second sliding body 1412.

[0041] In a possible implementation, the front part 110 of the shoe is slidably connected to the rear part 120 of the shoe. Wherein, the connection part between the front part 110 and the rear part 120 of the shoe partially overlaps. By releasing the partially overlapping area, it is adapted to adjust the length of the main sliding member 141. In a specific application, the front part 110 of the shoe and the rear part 120 of the shoe are slidably connected. When the first blade sliding body 1411 and the second sliding body 1412 of the main sliding member 141 slide relative to each other, the front part 110 of the shoe and the rear part 120 of the shoe also slide relative to each other to adapt to the relative sliding of the first blade sliding body 1411 and the second sliding body 1412, so as to realize the adjustment of the size of the ice and snow reuse shoe 100. Wherein, the connection part between the front part 110 and the rear part 120 of the shoe partially overlaps. When the front part 110 of the shoe expands and contracts relative to the rear part 120 of the shoe, a partially overlapping area can be released to adapt to the length adjustment of the main sliding member 141, so that the front part 110 and the rear part 120 of the shoe always maintain a tight connection, avoiding hollowing out and freezing the user.

[0042] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
