Description

Technical Field

[0001] The utility model relates to a shoe accessory and a shoe, in particular to a speed regulating buckle and a shoe with the speed regulating buckle. Background Art

[0002] In the second half of a marathon or a cross-country race, after a long period of running, the shoes often squeeze the feet due to collapsed arches and swollen feet. It is necessary to adjust the tightness of the shoelaces and then adjust the internal space of the shoe cavity to improve the comfort of the shoes.

[0003] Most traditional sports shoes adjust the tightness of the shoelaces by manually tightening the shoelaces. Every time the shoelaces are adjusted, the user needs to stop and re-tie the shoelaces, which seriously affects the running rhythm. Currently, there are many speed-adjusting buckles on the market that can quickly adjust the tightness of shoelaces. However, these speed-adjusting buckles usually need to be used with specific shoelaces, and even need to be preset on the shoelaces. They cannot be used on traditional shoes, and the replacement cost is relatively high. In addition, these speed-adjusting buckles usually do not have a gear adjustment function, making it difficult for users to pre-set the tightness of the shoelaces that suits them, and there is still a certain impact on the control of the running rhythm.

[0004] In view of this, the applicant conducted an in-depth study on the structure of the multi-wire cutting machine, which resulted in this case. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figure 1-Figure 4 As shown, this embodiment provides a shoe, in particular, a professional running shoe for marathon running or cross-country racing, which includes an upper 10, a sole connected to the upper (not shown in the figure), and a shoelace 20 tied to the upper 10, wherein the specific connection structure between the upper 10 and the sole is the same as that of a conventional running shoe and will not be described in detail here.

[0032] The structure of the upper 10 is the same as that of a conventional running shoe. Specifically, two groups of shoelace holes are provided on the upper 10. Both groups of shoelace holes include a plurality of shoelace holes 11 arranged in a roughly straight line. The number of shoelace holes 11 in the two groups of shoelace holes is the same and they are arranged one-to-one.

[0033] The shoelace 20 is inserted into all or part of the shoelace holes 11 at the same time. The specific insertion method can be determined according to actual needs, but it is necessary to ensure that there are at least two adjacent shoelace holes in each group of shoelace holes, and the shoelace section inserted between the two adjacent shoelace holes is not inserted in any shoelace hole.

[0034] The shoes provided in this embodiment also include a speed regulating buckle 30, which can be sold independently or in combination with other shoes, that is, this embodiment substantially also provides a speed regulating buckle. The speed regulating buckle 30 includes a first buckle body 40, a second buckle body 50 and an operating rod 60, wherein the first buckle body 40 includes an integrally connected connecting portion 41 and a first hook portion 42 for hooking the shoelace 20, the connecting portion 41 is columnar, and is provided with a blind hole 43 and a through hole 44 arranged perpendicular to the blind hole 43, the blind hole 43 and the through hole 44 are interconnected, the first hook portion 42 is connected to the side wall of the connecting portion 41 penetrated by the tube through hole 44, and the first hook portion 42 and the through hole 44 are arranged in a staggered manner with respect to each other, preferably, in this embodiment, the first hook portion 42 is located above the mouth corresponding to the tube through hole 44. The second buckle body 50 includes an insert plate 51 inserted in the through hole 44 and a second hook portion 52 integrally connected to one end of the insert plate 51, the second hook portion 52 is used to hook the shoelace 20, and a ratchet bar 53 arranged parallel to the insert plate 52 is fixedly connected or integrally connected to the insert plate 51, the ratchet bar 53 has a ratchet side facing the bottom of the blind hole 43, the ratchet side facing the second hook portion 52 has a blocking surface, and the other corresponding side has an inclined guide surface; the first hook portion 42 and the second hook portion 52 are respectively located on both sides of the connecting portion 41, and the outer contour diameter of the second hook portion 52 is larger than the inner contour diameter of the tube through hole 44 to ensure that the second hook portion 52 will not penetrate into the tube through hole 44.

[0035] One end of the operating rod 60 is inserted and slidably inserted into the blind hole 43, and the other end is located outside the blind hole 43 for operation during use. The operating rod 60 is provided with a through slot 61 for the ratchet bar 53 to pass through. The slot width of the through slot 61 is greater than the thickness of the ratchet bar 53 to ensure that the operating rod 60 can slide along the axial direction of the blind hole 43. A ratchet pawl cooperating with the ratchet bar 53 is provided on the side wall of the through slot 61 on the side relatively close to the bottom of the blind hole 43. In addition, a return spring 62 is provided between the bottom of the blind hole 43 and the operating rod 60. In this way, under the action of the return spring, the operating rod 60 will be lifted toward the mouth of the blind hole 43, so that the ratchet pawl and the ratchet bar 53 are engaged, so that the first hook 42 and the second hook 52 cannot move back to back, thereby maintaining the predetermined tightness of the shoelace 20; when the tightness of the shoelace 20 needs to be increased, the first hook 42 and the second hook 52 only need to be pressed toward each other so that the two move toward each other. When the tightness of the shoelace 20 needs to be reduced, the operating rod 60 is pressed toward the bottom of the blind hole 43 to separate the pawl from the ratchet bar 53. At this time, the first hook 42 and the second hook 52 will move away from each other under the pulling force of the shoelace 20, so that the tightness of the shoelace 20 is reduced. Of course, if the first hook 42 and the second hook 52 cannot move away from each other because the shoelace 20 is not tightened, the first hook 42 and the second hook 52 can also be manually pushed to move away from each other. In addition, in the process of adjusting the tightness, the ratchets on the ratchet bar 53 can be used as gears. The user can preset a shoelace tightness that suits him or her according to the relative position relationship between the pawl and the ratchet bar, so as to reduce the number of times the shoelace tightness needs to be adjusted in the second half of running without squeezing the foot.

[0036] Preferably, in order to prevent the reset spring 62 from shifting under the action of external force during use, in this embodiment, a guide rod 63 inserted into the reset spring 62 is integrally connected to the operating rod 60. The guide rod 63 also has a limiting function to prevent the reset spring 62 from being over-compressed.

[0037] Preferably, in order to prevent the shoelace 20 from slipping off the hook, in the present embodiment, the mouths of the first hook 42 and the second hook 52 are provided with protrusions, and the specific shape of the protrusions can be determined according to actual needs, such as a convex arc shape.

[0038] Preferably, a limiting block 54 is provided at one end of the inserting plate 51 away from the second hook portion 52, and the limiting block 54 can be clamped on the shoe tongue to reduce the possibility of the speed regulating buckle being offset to the left and right.

[0039] The speed adjustment buckle 30 is located between the two groups of shoelace hole groups, and preferably at a position corresponding to the arch of the shoe, so that the adjustment effect on the problem of squeezing the foot in the second half of running is the best. The first hook 42 and the second hook 52 of the speed adjustment buckle 30 both hook the shoelace 20, and the two ends of the shoelace 20 hooked by the first hook 42 are inserted one-to-one into two adjacent shoelace holes in one group of shoelace hole groups, and the two ends of the shoelace 20 hooked by the second hook 52 are inserted one-to-one into two adjacent shoelace holes in the other group of shoelace hole groups, that is, the shoelace segment inserted between two adjacent shoelace holes in the same shoelace hole group is hooked on the corresponding hook, so that the tightness adjustment can be achieved.
