Description

Shoelace anti-swing device Technical Field

[0001] The present invention relates to the technical field of auxiliary products for lacing shoes, in particular to a shoelace anti-swing device which can be used on lacing shoes such as sports shoes. Background Art

[0002] Currently, most sports shoes, casual shoes, and other shoes use shoelaces to adjust the tightness of the shoes, ensuring a better fit around the foot. The shoes are equipped with two rows of eyelets for the shoelaces to pass through. After the ends of the shoelaces are passed through the eyelets, they form a cross knot on the upper. The excess length of the shoelaces is then tied into a knot near the shoe opening. In actual use, this knot is often exposed on the upper (typically located on or above the tongue). The knot can swing while walking or running, compromising the user's safety and comfort. For example, the swinging knot can snag on objects or cause accidental stepping, leading to stumbling or falling. This is particularly common during outdoor activities such as hiking and mountaineering. This is especially true for sports shoes worn in the jungle, where foreign objects of various shapes can easily snag on the knot, causing falls. Furthermore, the swinging knot can touch the ankle. For runners, this foreign body sensation can affect comfort and distract the athlete during competition, resulting in a poor user experience.

[0003] Shoes in the prior art have been improved to address the above-mentioned problems. For example, as shown in the Chinese utility model patent No. CN201220323249.2 (authorization announcement No. CN202738960U) "Shoelace Hiding Structure", the structure includes a pocket for storing shoelace knots. The pocket is provided on the tongue, and the bag surface layer of the pocket is sewn to the tongue to form a bag cavity opening upward or downward, and an elastic band is provided on the edge of the bag surface layer at the opening. The elastic band can press the shoelace knot tightly into the pocket to prevent the knot from swinging and falling out of the pocket, thereby preventing dangers caused by loose shoelaces, stepping on, or tripping.

[0004] Although the above structure can store the tied shoelace knot in the tongue pocket to prevent the knot from swinging, in actual use, the tied shoelace knot may be too long, resulting in the knot not being able to be placed snugly in the pocket, affecting the user's comfort; even the overly long knot may not be able to be placed entirely in the pocket, and part of the knot may still be exposed on the tongue and swing, thus affecting the user's safety; and the pocket is fixedly connected to the tongue, so the pocket cannot be used on the user's original shoes, and the user can only buy new shoes with a pocket; in addition, the position of the pocket on the tongue cannot be changed, and different users may tie the knot in different positions on their shoes, making it impossible for the user to use the pocket in the most appropriate position to store the knot, thus affecting the user's experience. Therefore, further improvements are needed to the shoelace anti-swing device.

[0005] Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a shoelace anti-swing device that can fix a longer knot and is convenient and flexible to operate in actual use in response to the above-mentioned existing technical status.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: the shoelace anti-swing device is characterized in that it includes a pressing belt and at least two perforated parts; the two ends of the pressing belt are respectively connected to a perforated part, and each perforated part has a through hole for the shoelace to pass through.

[0008] In order to achieve a better effect of the pressing belt pressing the shoelaces, preferably, the pressing belt and the perforated portion are both made of elastic material, and the at least two perforated portions are integrally connected to the pressing belt. The pressing belt can use its own elasticity to press the knot and free end of the shoelaces to prevent the shoelaces from swinging.

[0009] Preferably, there are two perforated portions, the annular side wall of each perforated portion is connected to the end edge of the pressing belt, and the direction of the through hole in each perforated portion is consistent with the extension direction of the pressing belt.

[0010] Furthermore, the angle between the axis of the through hole in the perforated portion and the center line of the pressing belt is an acute angle. The user can grasp the top surface of the perforated portion and pull the pressing belt to make the knot and the free end of the shoelace more snugly pressed by the pressing belt.

[0011] Furthermore, a limiting friction wall extends from the bottom of each perforated portion toward the inner center. When the shoelace passes through the through hole, it contacts the limiting friction wall to generate friction, thereby further limiting the entire shoelace anti-swing device on the shoelace.

[0012] There can be many structures of the perforated portion and the connection method with the pressing belt. Preferably, there are two perforated portions, the top of each perforated portion is connected to the top edge of each end of the pressing belt, and the direction of the through hole in each perforated portion is roughly perpendicular to the extension direction of the pressing belt.

[0013] There can be many structures of the perforated portion and the connection method with the pressing belt. Preferably, there are three perforated portions, the tops of two perforated portions are connected to the top edges of each end of the pressing belt, and the top of one perforated portion is connected to the bottom of the middle part of the pressing belt, and the direction of the through holes in each perforated portion is roughly perpendicular to the extension direction of the pressing belt.

[0014] In order to facilitate the user to pinch the pressing belt, the outer surface of the pressing belt is provided with a plurality of protrusions, and the protrusions are arranged in the middle of the pressing belt. The plurality of protrusions can increase the friction force, making it easier for the user to pinch the protrusions and pull up the pressing belt.

[0015] The structure of the pressing belt can be various. Preferably, the cross-section of the pressing belt is C-shaped, and a crack is opened in the center of the pressing belt along the extension direction, which separates the pressing belt into two pressing belt branches, and a plurality of protrusions are provided on the surface of each pressing belt branch.

[0016] The structure of the pressing belt can be various. Preferably, the cross-section of the pressing belt is C-shaped, and two cracks are opened on the pressing belt along the extension direction. The directions of the two cracks are staggered to separate the pressing belt into three pressing belt branches with different thicknesses, thereby providing three pressing belt branches to meet the demand for multiple pressing belts in various situations.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The shoelace anti-swing device utilizes a perforated portion to achieve a detachable connection with the shoelaces. Therefore, the shoelace anti-swing device can be independent of the finished shoe and the shoelaces. That is, the shoelace anti-swing device can not only prevent the shoelaces from swinging, but can also be applied horizontally or vertically to existing lace-up shoes, making the shoelace anti-swing device more widely applicable and suitable for laced shoes with different uppers.

[0019] 2. The shoelace anti-swing device can be installed at a suitable position according to the needs of the user. That is, if the tied knot is too long, the shoelace anti-swing device can be installed away from the knot through the perforated part, and then the tied knot and the free end of the shoelace can be pressed down by the pressing belt to prevent the excessively long knot and free end from swinging and affecting the safety and comfort of the user.

[0020] 3. The shoelace anti-swing device has a simple structure and low production cost. In actual use, if the shoelace anti-swing device is damaged or the user has a different style, the user can replace the shoelace anti-swing device with a new one.

[0021] 4. The shoelace anti-swing device made of elastic material is installed on the shoelace through the perforated portion. In actual use, the shoelace anti-swing device will not cause additional damage to the upper and shoelaces of the finished shoe;

[0022] 5. The shoelace anti-swing device is easy to operate. The pulling up of the pressing belt and the inserting of the knot are performed after the shoelaces are tied. Therefore, the installation and use of the shoelace anti-swing device of the present invention will not affect the tightness of the completed knot at all. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] As shown in FIG1-FIG3, it is the first preferred embodiment of the shoelace anti-swing device of the present invention, namely embodiment 1.

[0033] As shown in Figures 1 and 2, the shoelace anti-swing device includes a pressing belt 1 and two perforated portions 2. The two ends of the pressing belt 1 are respectively connected to a perforated portion 2. In this embodiment, the pressing belt 1 and the perforated portion 2 are both made of elastic material, and the two perforated portions 2 are integrally connected to the pressing belt 1. In other embodiments, the two perforated portions 2 and the pressing belt 1 can be connected together using existing technologies, such as snap connection, bonding, etc.

[0034] The cross section of the pressing belt 1 is C-shaped with the opening facing downward. Each perforated portion 2 is roughly annular and has an annular side wall 23. The annular side wall 23 of each perforated portion 2 matches the edge size of the C-shaped end of the pressing belt 1 and is connected as a whole.

[0035] A through hole 21 for shoelaces to pass through is provided in the center of each annular perforated portion 2. In this embodiment, the direction of each through hole 21 is consistent with the extension direction of the pressing belt 1, that is, the through hole 21 of the perforated portion 2 is located below the top of the pressing belt 1.

[0036] When using the shoelace anti-swing device of the present invention, a shoelace on the upper is continuously passed through the through holes 21 of the two perforated portions 2. The shoelace anti-swing device is then installed on the shoelace and securely secured to the upper. In this embodiment, the shoelace anti-swing device is installed along the shoelace, i.e., the installation direction is consistent with the direction of the shoelace being worn. The user can pull up the pressing belt 1 and insert the knot and the two free ends 3 of the shoelace under the pressing belt 1. The pressing belt 1 then suppresses the knot and the two free ends 3 of the shoelace, thereby preventing the shoelace from swinging (see Figure 3).

[0037] Among them, a limiting friction wall 22 extends from the bottom of each perforated portion 2 toward the inner center. When the shoelace passes through the through hole 21, it contacts the limiting friction wall 22 to generate friction, thereby more reliably limiting the entire shoelace anti-swing device on the shoelace.

[0038] In addition, six protrusions 11 are provided on the outer surface of the pressing belt 1, three protrusions 11 form a group, and two groups of protrusions 11 are arranged on both sides of the middle of the pressing belt 1. The user pinches the protrusions 11 of the elastic pressing belt 1 with his hands to generate friction, thereby making it easier for the user to pull up the elastic pressing belt 1.

[0039] The installation steps of this embodiment are:

[0040] A. When the two ends of the shoelace are inserted through the shoe holes, the user presses the knot and the two free ends 3 of the shoelace, and then passes the shoelace head at one end of the shoelace through the through holes 21 of the two perforated parts 2 in succession, so that the shoelace anti-swing device is installed on the shoelace. The limiting friction wall 22 can rub against the shoelace, so that the shoelace anti-swing device is reliably fixed on the shoelace;

[0041] B. Continue threading the two ends of the shoelace through the eyelets. When the shoelaces are threaded through the eyelets, tie a knot at the shoe opening to form a knot and two free ends of the shoelaces.

[0042] C. The user pinches the raised point 11 on the elastic pressing belt 1 with his hand, pulls up the elastic pressing belt 1, and stuffs the knot and the two free ends 3 of the shoelaces under the elastic pressing belt 1. After releasing his hand, the elastic pressing belt 1 naturally presses the knot and the two free ends 3 of the shoelaces. The final pressing effect is shown in Figure 3.

[0043] As shown in FIG. 4 and FIG. 5 , this is Example 2 of the present invention.

[0044] As shown in Figure 4, the difference between this embodiment 2 and embodiment 1 is that the direction of the through hole 21 in each perforated portion 2 is approximately perpendicular to the extension direction of the pressing belt 1, that is, in this embodiment, the top of each perforated portion 2 is integrally connected to the top edge of the corresponding end of the pressing belt 1, and the through hole 21 of each perforated portion 2 is located below the top of the pressing belt 1.

[0045] When the distance between the two rows of shoe holes is small, the shoelace anti-swing device of Example 1, which spans horizontally between the two rows of shoe holes, is not sufficient to accommodate the shoelace anti-swing device of Figure 3. In this case, the shoelace anti-swing device of Example 2 is very suitable. When using the shoelace anti-swing device of Example 2, the shoelace anti-swing device is installed on the shoelace through the through holes 21 of the two perforated portions 2. Specifically, the upper of the shoe is provided with two rows of shoe holes, and the two ends of each shoelace pass through the two rows of shoe holes in sequence to form multiple intersections. The two perforated portions 2 of the shoelace anti-swing device pass through a single or two shoelaces at the two intersections in sequence, so that the two perforated portions 2 are installed at the two intersections of the shoelace, thereby installing the shoelace anti-swing device on the shoelace. At this time, the installation direction of the shoelace anti-swing device is consistent with the extension direction of the shoe itself (or the direction of the shoe tongue). The user can pull up the elastic pressing belt 1, put the knot and the two free ends 3 of the shoelaces under the elastic pressing belt 1, and use the elastic pressing belt 1 to press the knot and the two free ends 3 of the shoelaces to prevent the shoelaces from swinging, see Figure 5.

[0046] The installation steps of this embodiment are:

[0047] A. When the two ends of the shoelace are threaded through the shoe holes, the user presses down the knot and the two free ends 3 of the shoelace, passes the end of the shoelace through the through hole 21 of one perforated portion 2, and then passes the ends of the shoelace through one shoe hole respectively to form a cross point; then passes the end of the shoelace 3 through the through hole 21 of the other perforated portion 2, thereby installing the shoelace anti-swing device on the shoelace;

[0048] B. Continue threading the two ends of the shoelace through the eyelets. When the shoelaces are threaded through the eyelets, tie a knot at the shoe opening to form a knot and two free ends of the shoelaces.

[0049] C. The user pulls up the elastic pressing belt 1 with his hands and places the shoelace knot and the two free ends 3 of the shoelaces under the elastic pressing belt 1. After letting go, the elastic pressing belt 1 naturally presses the knot and the two free ends 3 of the shoelaces. The final pressing effect is shown in Figure 5.

[0050] As shown in FIG6 , this is Example 3 of the present invention.

[0051] As shown in Figure 6, the difference between Example 3 and Example 2 is that the shoelace anti-swing device has three perforated portions 2, of which the tops of two perforated portions 2 are integrally connected to the top edges of one end of the pressing belt 1, and the top of one perforated portion 2 is integrally connected to the bottom of the middle portion of the elastic pressing belt 1. The through holes 21 of each perforated portion 2 are located below the top of the pressing belt 1. In this case, the three perforated portions 2 are sequentially referred to as the first perforated portion 2a, the second perforated portion 2b, and the third perforated portion 2c. The second perforated portion 2b located in the middle portion divides the pressing belt 1 into two sections, and both sections of the pressing belt 1 can be used as the locations for pressing the knot and the two free ends 3 of the shoelace.

[0052] The shoelace anti-swaying device of the present embodiment is provided with a through hole 21 of three perforated portions 2, specifically, the shoe upper is provided with two rows of shoe holes, the two ends of each shoelace are passed through the two rows of shoe holes successively to form a plurality of intersections, the three perforated portions 2 of the shoelace anti-swaying device are passed through the shoelace on the three intersections successively, the three intersections are passed through a corresponding perforated portion 2 respectively, like this, the installation direction of the shoelace anti-swaying device is consistent with the extension direction (or the direction of the tongue) of the shoe itself. The user pulls up one section of the elastic pressing band 1 of the appropriate position according to the length of the knot and the two shoelace free ends 3, inserts the knot and the two shoelace free ends 3 into the below of the appropriate section in the elastic pressing band 1, utilizes the elastic pressing band 1 that the knot and the two shoelace free ends 3 are suppressed, thereby prevents the shoelace from swinging. In actual use, because the knot and the two shoelace free ends 3 have different lengths, the user can also pull up two sections of pressing bands 1 simultaneously, and the two sections of pressing bands 1 all play a suppressing effect.

[0053] The installation steps of this embodiment are:

[0054] A. When the two ends of the shoelace are threaded through the shoeholes, the user presses the knot and the two free ends 3 of the shoelaces, passes the end of the shoelace through the through hole 21 of the first perforated portion 2a, and then passes the ends of the shoelace through one shoehole to form an intersection; then passes the end of the shoelace through the through hole 21 of the second perforated portion 2b, and then passes the ends of the shoelace through another shoehole to form another intersection; finally, passes the end of the shoelace through the through hole 21 of the third perforated portion 2c, thereby installing the shoelace anti-swing device on the shoelace 3;

[0055] B. Continue threading the two ends of the shoelace through the eyelets. When the shoelaces are threaded through the eyelets, tie a knot at the shoe opening to form a knot and two free ends of the shoelaces.

[0056] C. The user pulls up one section of the pressing belt 1 and places the shoelace knot and the two free ends 3 under the elastic pressing belt 1. After letting go, the elastic pressing belt 1 naturally presses the knot and the two free ends 3 of the shoelace.

[0057] As shown in FIG. 7 and FIG. 8 , this is Example 4 of the present invention.

[0058] As shown in Figures 7 and 8, the structure of Example 4 is basically similar to that of Example 1, except that a crack 12 is provided in the center of the pressing belt 1 of this embodiment along the extension direction, which divides the pressing belt 1 into two pressing belt branches 1a, and two groups of protrusions 11 are provided on the surface of each pressing belt branch 1a, and the protrusions 11 are provided in the middle of the pressing belt 1.

[0059] By utilizing the protruding points 11 , the user can grasp the pressing belt 1 more quickly and effectively. The two pressing belt branches 1 a of this embodiment provide more pressing locations for pressing the knot and the two free ends 3 of the shoelaces.

[0060] The installation process of this embodiment 4 is similar to that of embodiment 1, with the difference being that: after the shoelaces are tied at the shoe opening, the user pinches the convex point 11 on one pressing belt branch 1a with his hand, and then pulls up the pressing belt branch 1a, and places a part of the knot and the two free ends 3 of the shoelaces under the pressing belt branch 1a, so that the pressing belt branch 1a presses part of the knot and the two free ends 3 of the shoelaces; then the user pinches the convex point 11 on the other pressing belt branch 1a with his hand, and pulls up the pressing belt branch 1a, and places the remaining part of the knot and the two free ends 3 of the shoelaces under the pressing belt branch 1a, so that the two pressing belt branches 1a press the knot and the two free ends 3 of the shoelaces.

[0061] The pressing belts 1 in the above four embodiments can be designed into different shapes, patterns and colors to decorate shoes and meet the personalized usage needs of users.
