Description

Technical Field

[0001] The utility model relates to the technical field of roller skates, in particular to an improved roller skate. Background Art

[0002] As people pursue a more leisurely and active lifestyle, roller skating and inline skating are becoming increasingly popular. While traditional roller skates have improved in functionality and comfort, they still have some shortcomings in adapting to different foot shapes and sizes. For example, growing children's feet tend to enlarge over time, necessitating the need for larger shoes. However, such frequent changes in skates incur additional expenses, necessitating the design of shoes that can adjust to the size of children's feet.

[0003] In order to solve the above problems, authorization announcement number CN210353407U discloses an adjustment structure and roller skates that can simultaneously adjust the length and width of skates, which specifically discloses a sole and a toe mounted on the sole; the thickness of the sole gradually decreases from the rear end to the middle and the upper surface of the sole is an arc-shaped surface that gradually decreases from high to low from the rear end to the middle; the toe is provided with a strip-shaped dividing groove that divides the toe into a toe main body and a toe adjusting body along the length direction; a first strip guide groove extending from rear to front is provided in the toe main body; a first positioning column inserted in the first strip guide groove is provided on the sole; a second strip guide groove gradually expanding outward from rear to front is provided at the rear end of the toe adjusting body; a second positioning column inserted in the second strip guide groove is provided on the sole; the rear end of the toe main body is inserted in an open groove provided at the rear end of the sole; and an adjustment mechanism for pushing the toe to slide back and forth is provided in the open groove.

[0004] Although the above-mentioned shoes have the function of adjusting the size, there are still some areas that need improvement. For example, a strip-shaped dividing groove is provided on the toe, so that when the toe slides, the two ends of the toe formed by the strip-shaped dividing groove are squeezed and deformed with the side walls of the sole, thereby adjusting the toe width. However, in this adjustment, only one side of the toe actively shrinks and deforms after being squeezed, while the other end cannot shrink and deform accordingly due to the limitation of the second positioning column. Therefore, only one-sided deformation is used, which is not more accurate when adjusting the toe width and cannot well adapt to the needs of different foot shapes. In addition, the part of the toe divided by the dividing groove is prone to unconstrained deformation during the squeezing process, which causes the toe to warp up, making the entire toe part less flat, which also makes it less comfortable to wear the shoes. Finally, the locking wrench is exposed outside the sole when locked, which makes it easy to touch the locking wrench and cause the entire adjustment structure to loosen.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

[0006] In response to the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an improved roller skate, which makes the adjustment of the toe of the shoe more precise and convenient by cooperating with the guide column and the two dividing grooves; in addition, by providing a pressure plate, the toe of the shoe can be prevented from warping up when it contracts or expands; finally, the hidden setting of the locking wrench can effectively prevent the problem of the adjustment device loosening due to touch.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

[0008] 18. The shoe of claim 17, wherein the shoe body comprises a toe portion and an adjusting device for driving the toe portion to slide along the length direction of the shoe body; two dividing grooves are longitudinally provided at the front end of the toe portion, and a guide post is provided on the shoe body and can be inserted into the dividing grooves, so that the two dividing grooves and the two guide posts can conveniently adjust the width of the toe portion and the length of the toe portion when the two dividing grooves and the two guide posts are movably matched, so that the toe portion can also be adaptively adjusted; a toe pressing plate is provided on the toe portion and above the two dividing grooves, the toe pressing plate is fixedly connected to the toe portion by rivets, so that when the toe portion slides, the front end of the toe portion can expand or contract horizontally under the constraint of the toe pressing plate; an embedding groove is provided at the rear end of the shoe body, and a through hole is provided in the embedding groove that passes through the embedding groove; the adjusting device comprises an adjusting screw that passes through the through hole and is screwed to the toe portion, and a locking wrench that can be embedded in the embedding groove and used to lock the adjusting screw; when the locking wrench is embedded in the embedding groove, the adjusting device can be prevented from loosening.

[0009] Furthermore, the dividing groove can divide the front end of the toe portion into a first adjustment piece and a second adjustment piece. The first adjustment piece and the second adjustment piece can respectively abut against the side wall of the shoe body when the toe portion slides, so that the first adjustment piece and the second adjustment piece can adjust the width of the toe portion after being squeezed and deformed. With the above arrangement, when the toe portion slides, both the first adjustment piece and the second adjustment piece can actively deform during the squeezing process, thereby achieving the purpose of more precise adjustment of the toe portion width.

[0010] Furthermore, the dividing groove includes a positioning hole for securing the guide post, and a first section, a second section, and a third section extending from the positioning hole toward the rear end of the toe portion. The first section and the second section extend obliquely toward the sides of the toe portion, respectively, while the second section extends obliquely toward the middle of the toe portion. This arrangement creates a multi-stage deformation zone in the dividing groove, allowing the toe portion to be adjusted accordingly based on foot size.

[0011] Furthermore, a toe press plate mounting groove is provided on the toe portion of the shoe for positioning and mounting the toe press plate. Through the above arrangement, when the toe press plate is fixed to the toe portion of the shoe, the upper end surface of the toe press plate can be flush with the upper end surface of the toe portion, thus making the flat toe portion of the shoe more comfortable to wear.

[0012] Furthermore, a guide rail is protruded from the bottom of the toe portion along its length, and a guide rail groove is provided on the shoe body to slide with the guide rail. Through the above arrangement, when the toe portion slides along the length of the shoe body, the guide rail can slide directionally in the guide rail groove.

[0013] Furthermore, a positioning post is provided in the shoe body, and a strip groove for the positioning post to pass through is provided on the toe portion and the toe pressing plate. The positioning post cooperates with the strip groove so that the toe portion and the toe pressing plate can slide directionally relative to the shoe body.

[0014] Furthermore, a pushing block threadedly connected to the adjusting screw is fixedly provided at the bottom of the toe portion.

[0015] Furthermore, the pushing block is integrally connected to the toe portion.

[0016] Furthermore, the improved roller skates also include a pulley support seat fixed to the bottom of the shoe body, and the pulley support seat and the shoe body are an integrated structure.

[0017] Furthermore, a plurality of pulleys are provided in the pulley support seat.

[0018] The beneficial effects of the utility model are:

[0038] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0039] like Figure 1-Figure 5 As shown, an improved roller skate comprises a shoe body 1, a toe portion 2 is provided inside the shoe body 1, and an adjusting device 3 for driving the toe portion 2 to slide along the length direction of the shoe body 1. In this embodiment, the toe portion 2 is driven to slide along the length direction of the shoe body 1 by the adjusting device 3, so that the side edge of the toe portion 2 is in contact with the side wall of the shoe body 1 during sliding, and the width of the toe portion 2 is adjusted by the contraction and expansion of the toe portion 2.

[0040] like Figure 4-Figure 5 As shown, two longitudinal dividing grooves 21 are defined at the front end of the toe portion 2. A guide post 13 is provided on the shoe body 1, which can be inserted into the dividing grooves 21. This allows the two dividing grooves 21 and the two guide posts 13 to cooperate with each other to conveniently adjust the width of the toe portion 2 while also correspondingly adjusting its length. In this embodiment, the toe portion 2 can extend or contract relative to the length of the shoe body 1 as it slides along the length of the shoe body 1. Specifically, the dividing grooves 21 divide the front end of the toe portion 2 into a first adjustment tab 22 and a second adjustment tab 23. The first and second adjustment tabs 22 and 23 can respectively abut against the sidewalls of the shoe body 1 as the toe portion 2 slides, allowing the first and second adjustment tabs 22 and 23 to adjust the width of the toe portion 2 after being squeezed and deformed. The guide posts 13 can slide relative to each other within the dividing grooves 21, thereby precisely guiding the sliding direction of the toe portion 2.

[0041] like Figure 4 As shown, the separating groove 21 further includes a positioning hole 210 for fixing the guide post 13, and a first section 211, a second section 212, and a third section 213 extending from the positioning hole 210 toward the rear end of the toe portion 2. The first section 211 and the second section 212 extend obliquely toward the sides of the toe portion 2, respectively, while the second section 212 extends obliquely toward the middle of the toe portion 2. The oblique arrangement of the first section 211, the second section 212, and the third section 213 allows the separating groove 21 to have multiple deformation zones, allowing the toe portion 2 to be adjusted accordingly based on the size of the foot.

[0042] like Figure 1-Figure 5As shown, a toe pressure plate 4 is provided on the toe portion 2 and above the two dividing grooves 21. The toe pressure plate 4 is fixedly connected to the toe portion 2 by a rivet 43, so that when the toe portion 2 slides, the front end of the toe portion 2 can expand or contract horizontally under the constraint of the toe pressure plate 4; in this embodiment, the first adjustment piece 22 and the second adjustment piece 23 respectively abut against the side walls of the shoe body 1, and when the toe portion 2 slides along the length direction of the shoe body 1, the first adjustment piece 22 and the second adjustment piece 23 may be squeezed and deformed (such as warping). The deformed toe portion 2 is not flat enough when worn, which will make the user uncomfortable when wearing the shoe; therefore, by providing a toe pressure plate 4 on the toe portion 2 and above the two dividing grooves 21, the first adjustment piece 22 and the second adjustment piece 23 can expand and contract below the toe pressure plate 4, thereby avoiding the technical problem of the first adjustment piece 22 and the second adjustment piece 23 warping, which also allows the user to have a comfortable experience when wearing the shoe.

[0043] like Figure 1 and Figure 4 As shown, in this embodiment, a toe pressure plate mounting groove 24 for positioning and mounting the toe pressure plate 4 is provided in the toe portion 2; specifically, a first pressure plate hole 41 and a second pressure plate hole 42 are provided on the toe pressure plate 4, and a first toe hole 25 and a second toe hole 26 are provided on the toe portion 2; a rivet 43 passes through the first pressure plate hole 41 and the first toe hole 25 and fixes the toe pressure plate 4 to the toe portion 2, and the rivet 43 passes through the second pressure plate hole 42 and the second toe hole 26 and fixes the toe pressure plate 4 to the toe portion 2; through the above-mentioned arrangement, when the toe pressure plate 4 is fixed to the toe portion 2, the upper end surface of the toe pressure plate 4 can be flush with the upper end surface of the toe portion 2, which makes the flat toe portion 2 have a more comfortable wearing experience when wearing shoes.

[0044] like Figure 2 As shown, the rear end of the shoe body 1 is provided with an embedding groove 11, and a through hole 12 is provided in the embedding groove 11, which passes through the embedding groove 11; the adjustment device 2 includes an adjustment screw 31 that passes through the through hole 12 and is screwed to the toe 2, and a locking wrench 32 that can be embedded in the embedding groove 11 and is used to lock the adjustment screw 31; when the locking wrench 32 is embedded in the embedding groove 11, it can prevent the adjustment device 3 from loosening. Specifically, a push block 33 that is screwed to the adjustment screw 31 is fixed at the bottom of the toe 2, wherein the push block 33 is integrally connected to the toe 2. Through the above-mentioned arrangement, the locking wrench 32 is a hidden design, so that after the locking wrench 32 is folded and locked into the embedding groove 11, it can prevent the problem of touching the locking wrench 32 and causing the entire adjustment device 3 to loosen.

[0045] like Figure 1 and Figure 3As shown, a guide rail 5 is protruded from the bottom of the toe portion 2 and along its length, and a guide rail groove 6 is formed on the shoe body 1 to slide with the guide rail 5. Through the above arrangement, when the toe portion 2 slides along the length of the shoe body 1, the guide rail 5 can slide in a directional manner within the guide rail groove 6.

[0046] like Figure 1 As shown, a positioning post 14 is further provided in the shoe body 1, and a strip groove 7 for the positioning post 14 to pass through is provided on the toe cap 2 and the toe pressure plate 4. Through the cooperation between the positioning post 14 and the strip groove 7, the toe cap 2 and the toe pressure plate 4 can slide relative to the shoe body 1 in a directional manner.

[0047] like Figure 1-Figure 3 As shown, the improved roller skates further include a pulley support seat 8 fixed to the bottom of the shoe body 1, and the pulley support seat 8 is an integral structure with the shoe body 1. In this embodiment, a plurality of pulleys 9 are provided in the pulley support seat 8.

[0048] To sum up, by providing two dividing grooves 21 on the toe portion 2 and providing a guide column 13 in the shoe body 1 that cooperates with the two dividing grooves 21, the first adjustment piece 22 and the second adjustment piece 23 formed after the corresponding division can synchronously form abutment with the side wall of the shoe body 1, and when the toe portion 2 slides, the first adjustment piece 22 and the second adjustment piece 23 can expand or contract more accurately, so as to achieve a more precise adjustment of the width of the toe portion 2.

[0049] In addition, a toe pressure plate 4 is provided on the toe portion 2 and above the dividing groove 21, so that the first adjustment piece 22 and the second adjustment piece 23 can expand or contract below the toe pressure plate 4, thereby preventing the first adjustment piece 22 and the second adjustment piece 23 from warping upward; at the same time, the setting of the toe pressure plate 4 can also keep the toe portion 2 flat, effectively improving the comfort when wearing shoes.

[0050] Finally, an embedding groove 11 is provided on the rear side of the shoe body 1, so that the locking wrench 32 can be embedded in the embedding groove 11 in the locked state, so that the locking wrench 32 after locking is a hidden setting, thereby preventing the technical problem of the entire adjustment device 3 becoming loose due to touching the locking wrench 32.

[0051] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
