Description

Technical Field

[0001] This invention relates to footwear components, specifically a shoelace clamping device. Background Technology

[0002] No shoe buckles with the same structural principle have been found on the market. A similar shoe buckle is the swivel buckle for shoelaces, but its structure is too complex, resulting in high production costs and making tightening and loosening shoelaces cumbersome. It fastens thin filaments; to fasten thick shoelaces, it requires a large cavity, making the buckle itself quite large and obtrusive on the shoe upper. Using thin filaments as shoelaces on shoe uppers is also relatively complex. Considering aesthetics, more processes are required, such as incorporating additional webbing to meet practical and aesthetic requirements, thus increasing production costs. Some shoes are better suited to thicker shoelaces for both aesthetics and convenience. Summary of the Invention

[0003] The present invention aims to provide a shoe buckle that can fasten thick shoelaces, thus meeting market demand.

[0004] The objective of this invention is achieved through the following technical solution: A shoelace combination buckle, characterized in that it comprises: a fixed buckle and a movable buckle. The fixed buckle has a base, on which a central post is fixed vertically in the middle. The function of the central post is to allow the shoelace to bend or loop. The fixed buckle includes a cover plate fixed to the top of the central post to prevent the shoelace from detaching from the central post.

[0005] The movable buckle has two resistance holes through which the shoelaces can pass. When the shoelace is slack, its cross-sectional area is larger than the cross-sectional area of ​​the resistance hole, thus creating resistance to the forward and backward pulling of the shoelace. This resistance hole acts as a constraint, preventing the shoelace from being pulled easily through. The section of the shoelace that extends forward through the resistance hole is called the "out-of-line" section.

[0006] The shoelaces that emerge from the eyelets on the upper need to enter the retaining buckle, hence this section is called the insertion section. The insertion sections on both sides enter the retaining buckle, wrap around the center post, and then pass through the resistance hole of the sliding buckle. When the insertion sections on both sides are pulled towards the eyelets on the upper, they encounter resistance from the resistance hole of the sliding buckle. Simultaneously, the shoelaces tightly wrap around the center post. Under this combined resistance, the insertion sections on both sides cannot be pulled further towards the sides of the upper.

[0007] When loosening the shoelaces, pull the movable buckle forward or upward along the threaded section of the shoelace to separate it from the fixed buckle. This not only frees the threaded section of the shoelace from the resistance hole of the movable buckle, but also releases the tension of the shoelace, causing the shoelace around the center post of the fixed buckle to loosen. The shoelace's slack is then released, and a section of shoelace can be easily pulled out from the fixed buckle at the threaded sections on both sides, achieving the purpose of loosening the shoelaces.

[0008] When tightening shoelaces, pull the out-of-lace section forward or upward by pinching the movable buckle. The previously loosened in-lace section will be pulled towards the movable buckle. Then, move the movable buckle backward along the shoelace and close to the front center of the fixed buckle. Because the cover of the fixed buckle blocks the movable buckle, the resistance hole of the movable buckle immediately applies resistance to the shoelace. The shoelace around the center post of the fixed buckle loses its free tension and must be tightly wrapped around the center post. At this point, the shoelace is fixed, and the in-lace sections on both sides cannot be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

[0009] The base of the aforementioned fastener is fixed with a center post and side posts. The center post is vertically fixed in the middle of the base, and the side posts are vertically fixed beside the center post, serving the same function as the center post. A cover plate is fixed to the top of the center post and side posts to prevent the shoelaces from detaching from them. The shoelaces on both sides enter the fastener, pass around the center post, then around the side post on the same side, and finally pass through the resistance hole of the movable buckle.

[0010] When the shoelaces on both sides are pulled towards the shoe upper eyelet, the shoelaces undergo multiple tight bends. The number of times the shoelaces are bent, the angle and tightness of the bends, as well as the cross-sectional size and material of the shoelaces are all important conditions for fastening the shoelaces in this invention. After the shoelaces are resisted by the resistance hole of the movable buckle, they will bend tightly multiple times in the fixed buckle. Under multiple resistances, the shoelaces on both sides cannot be pulled towards the sides of the shoe upper.

[0011] When loosening the shoelaces, pull the movable buckle forward or upward along the threaded section of the shoelace to disengage it from the fixed buckle. This not only frees the threaded section of the shoelace from the restraint hole of the movable buckle, but also releases the tension of the shoelace, causing the shoelace around the side post and center post of the fixed buckle to loosen. The shoelace's slackness is released, and at this point, a section of shoelace can be easily pulled out from the fixed buckle at the threaded section positions on both sides, achieving the purpose of loosening the shoelaces.

[0012] When tightening shoelaces, pull the protruding section of the shoelace forward or upward by pinching the movable buckle. The previously loosened section of the protruding shoelace will be pulled towards the movable buckle. Then, move the movable buckle backward along the shoelace and close to the front center of the fixed buckle. In this way, the shoelace protruding from the resistance hole of the movable buckle is separated to the left and right by the side post or cover of the fixed buckle, which is equivalent to pulling it laterally. If the shoelace in the resistance hole of the movable buckle is pulled vertically, it is easy to pull. However, if it is pulled laterally, the resistance increases significantly because pulling the shoelace laterally requires making a sharp 90-degree bend and tightly wrapping it. Any sharp bend in the shoelace increases resistance. At the same time, the resistance hole of the movable buckle immediately applies resistance to the shoelace. The shoelace around the side post and center post of the fixed buckle loses its free tension and must tightly wrap along the pre-set multiple sharp bends. At this point, the shoelace is fixed, and the protruding sections of the shoelace on both sides cannot be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

[0013] The base of the aforementioned fastener is fixed with two central posts. The shoelaces on both sides enter the fastener, pass around the central post on the same side, then around the side post on the same side, and finally pass through the resistance hole of the movable buckle. Tightening and loosening the shoelaces is performed as described above.

[0014] Two rear posts are fixed to the base of the aforementioned fastener. These rear posts function similarly to the side posts. The insert sections of the shoelaces on both sides enter the fastener, pass around the center post, then around the rear post on the same side, and finally pass through the resistance hole of the movable buckle. At this point, the movable buckle and the exit section of the shoelace are behind the fastener. To loosen the shoelaces, pull the movable buckle backward or upward along the exit section of the shoelace, causing it to disengage from the fastener. At this point, a section of the shoelace can be easily pulled out from the fastener at the position of the insert sections on both sides, thus loosening the shoelaces. To tighten the shoelaces, pull the exit section of the shoelace backward or upward by pinching the movable buckle. The previously loosened section of the insert section will be pulled towards the movable buckle. Then, move the movable buckle forward along the shoelace and press it against the rear center of the fastener, thus tightening the shoelaces.

[0015] The aforementioned movable buckle has two resistance holes connected by a through hole, which is larger in diameter than the resistance holes, allowing the shoelace end to be easily inserted. After the shoelace end passes through the through hole, the shoelace is then pulled into its respective resistance hole.

[0016] The movable buckle has two resistance holes with notches at the bottom. The notches are wider on the outside and narrower on the inside, so that the shoelaces can be pulled directly into the resistance holes. When lacing the shoes, the shoelace ends do not need to be inserted through the resistance holes.

[0017] The inner walls of the two resistance holes of the aforementioned movable buckle are provided with protruding strips to prevent the shoelace ends from coming off the resistance holes.

[0018] An auxiliary buckle is installed on the aforementioned shoelace extension. The shoelace extension passes through the hole provided by the auxiliary buckle, so that the movable buckle will not come off the shoelace extension.

[0019] The base of the aforementioned fastener has teeth fixed to the central and side posts, which can increase the resistance to the shoelaces when tightening them and help to fix the shoelaces without affecting the loosening of the shoelaces.

[0020] The outer ring of the base of the aforementioned fastener is a sewing outer ring, which allows the base of the fastener to be fixed to the shoe upper by sewing thread.

[0021] The bottom of the base of the aforementioned fastener is fixed to the shoe upper by adhesive.

[0022] The present invention has the following advantages: This invention has a simple structure, is inexpensive, and is easy to operate. It is designed for thicker shoelaces and is suitable for shoes with thicker shoelaces. Attached Figure Description

[0034] Figure 11 is a schematic diagram of the base of the fixing buckle in Figure 3, which has a rear post and the direction of the shoelaces. Implementation

[0035] refer to Figure 1 The shoelace combination buckle is characterized by comprising: a movable buckle 3 and a fixed buckle. The fixed buckle has a base 1, on which a central post 11 is fixedly and vertically in the middle. The function of the central post 11 is to allow the shoelace 100 to bend or loop. The fixed buckle includes a cover plate 2 fixed to the top of the central post 11 to prevent the shoelace 100 from detaching from the central post 11.

[0036] refer to Figure 6 Figure 7 The movable buckle 3 has two resistance holes 31 through which the shoelace 100 can pass. When the shoelace is slack, its cross-sectional area is larger than that of the resistance hole 31, so the resistance hole 31 provides resistance to the forward and backward pulling of the shoelace. The resistance hole 31 has a restraining effect on the shoelace, preventing it from being pulled easily through. The section of the shoelace that extends forward through the resistance hole 31 is called the outgoing shoelace section 103.

[0037] refer to Figure 1 The shoelace 100, which emerges from the shoe upper eyelet 4, needs to enter the retaining buckle, so this section of the shoelace is called the insertion section shoelace 102. The insertion sections 102 on both sides enter the retaining buckle, pass around the center post 11, and then pass through the resistance hole 31 of the movable buckle 3. When the insertion sections 102 on both sides are subjected to a pulling force towards the shoe upper eyelet 4, the shoelace will experience a certain resistance from the resistance hole 31 of the movable buckle 3. Simultaneously, the shoelace 100 will tightly wrap around the center post 11. Under multiple resistances, the insertion sections 102 on both sides cannot be pulled towards the sides of the shoe upper.

[0038] refer to Figure 2 When loosening the shoelaces, pull the movable buckle 3 forward or upward along the through section of shoelace 103 to disengage it from the fixed buckle. This not only frees the through section of shoelace 103 from the restraint hole 31 of the movable buckle 3, but also causes the shoelace around the center post 11 of the fixed buckle to loosen, releasing the slack of the shoelace. At this point, a section of shoelace can be easily pulled out from the fixed buckle at the positions of the through sections of shoelace 102 on both sides, thus achieving the purpose of loosening the shoelaces.

[0039] refer to Figure 1 Figure 2When tightening the shoelaces, pull the out-of-lace section 103 forward or upward by pinching the movable buckle 3. The previously loosened in-lace section 102 will be pulled towards the movable buckle 3. Then, the movable buckle 3 moves backward along the shoelace 100 and is close to the front middle of the fixed buckle. Because the cover plate 2 of the fixed buckle blocks the movable buckle 3, the resistance hole 31 of the movable buckle 3 immediately applies resistance to the shoelace. The shoelace around the center post 11 of the fixed buckle loses its free tension and must be tightly wrapped around the center post 11. At this time, the shoelace 100 is fixed, and the in-lace sections 102 on both sides cannot be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

[0040] refer to Figure 3 Figure 5 The base 1 of the aforementioned fixing buckle is fixedly provided with a center post 11 and a side post 12; the center post 11 is vertically fixed in the middle of the base 1, and the side post 12 is vertically fixed next to the center post 11. The side post has the same function as the center post. The fixing buckle is fixedly provided with a cover plate 2, which is fixed to the top of the center post 11 and the side post 12 to prevent the shoelaces from coming off the center post 11 and the side post 12. The shoelaces 102 on both sides enter the fixing buckle, pass around the center post 11, then pass around the side post 12 on the same side, and finally pass through the resistance hole 31 of the movable buckle 3.

[0041] refer to Figure 3 When the shoelaces 102 on both sides are pulled towards the shoe upper hole 4, the shoelaces undergo multiple tight bends. The number of times the shoelaces are bent, the angle and tightness of the bends, as well as the cross-sectional size and material of the shoelaces are all important conditions for fastening the shoelaces in this invention. After the shoelaces are resisted by the resistance hole 31 of the movable buckle 3, they will bend tightly multiple times in the fixed buckle. Under multiple resistances, the shoelaces 102 on both sides cannot be pulled towards the sides of the shoe upper.

[0042] refer to Figure 4 When loosening the shoelaces, pull the movable buckle 3 forward or upward along the through section of shoelace 103 to disengage it from the fixed buckle. This not only frees the through section of shoelace 103 from the restraint hole 31 of the movable buckle 3, but also causes the shoelace around the side post 12 and center post 11 of the fixed buckle to loosen, releasing the slackness of the shoelace. At this point, a section of shoelace can be easily pulled out from the fixed buckle at the positions of the through sections of shoelace 102 on both sides, achieving the purpose of loosening the shoelaces.

[0043] refer to Figure 3 Figure 4When tightening the shoelaces, pull the protruding section of the shoelace 103 forward or upward by pinching the movable buckle 3. The previously loosened section of the protruding section of the shoelace 102 will be pulled towards the movable buckle 3. Then, the movable buckle 3 moves backward along the shoelace and is close to the front middle of the fixed buckle. In this way, the shoelace coming out of the resistance hole 31 of the movable buckle 3 is separated to the left and right by the side post 12 or cover plate 2 of the fixed buckle, which is equivalent to pulling it horizontally. If the shoelace in the resistance hole 31 of the movable buckle 3 is pulled vertically, it is easy to pull. However, if it is pulled horizontally, the resistance will increase. This is because pulling the shoelace horizontally requires making a sharp 90-degree bend and tightly wrapping it. Any sharp bend in the shoelace will increase the resistance. At the same time, the resistance hole 31 of the movable buckle 3 immediately applies resistance to the shoelaces. The shoelaces around the side post 12 and the middle post 11 of the fixed buckle lose their free tension and must be tightly wrapped along the pre-set multiple sharp bends. At this time, the shoelaces are fixed, and the shoelaces 102 on both sides can not be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

[0044] refer to Figure 10 The base 1 of the aforementioned fixing buckle is fixed with two central posts 11. The shoelaces 102 on both sides enter the fixing buckle, pass around the central post 11 on the same side, then pass around the side post 12 on the same side, and finally pass through the resistance hole 31 of the movable buckle 3. The operation of loosening and tightening the shoelaces is the same as described above.

[0045] refer to Figure 11 Two rear posts 13 are fixed on the base 1 of the aforementioned fixing buckle. The function of the rear posts 13 is the same as that of the side posts 12. The shoelaces 102 on both sides enter the fixing buckle, pass around the middle post 11, and then pass around the rear post 13 on the same side, finally passing through the resistance hole 31 of the movable buckle 3. At this time, the movable buckle 3 and the shoelaces 103 are behind the fixing buckle. When loosening the shoelaces, the movable buckle 3 is pulled backward or upward along the shoelaces 103 to make the movable buckle 3 leave the fixing buckle. At this time, a section of shoelace can be easily pulled out from the fixing buckle at the position of the shoelaces 102 on both sides, thus achieving the purpose of loosening the shoelaces 100. When tightening the shoelaces, pull the out section of the shoelace 103 backward or upward by pinching the movable buckle 3. The previously loosened section of the in section of the shoelace 102 will be pulled towards the movable buckle 3. Then, the movable buckle 3 moves forward along the shoelace and is close to the middle of the rear end of the fixed buckle. At this time, the shoelace is tightened.

[0046] refer to Figure 7 The movable buckle 3 has two resistance holes 31 connected to a through hole 32. The through hole 32 is larger than the diameter of the resistance holes 31, so that the shoelace head 101 can be easily inserted into it. After the shoelace head 101 passes through the through hole 32, the shoelace is pulled into its respective resistance hole 31.

[0047] refer to Figure 8The movable buckle 3 has two resistance holes 31 with notches 34 at the bottom. The notches 34 are wider on the outside and narrower on the inside, so that the shoelaces can be pulled directly into the resistance holes 31. When putting on the shoelaces, the shoelace ends 101 do not need to be inserted through the holes of the resistance holes 31.

[0048] refer to Figure 7 Figure 8 The inner walls of the two resistance holes 31 of the aforementioned movable buckle 3 are provided with protrusions 33 to prevent the shoelace head 101 from disengaging from the resistance holes 31.

[0049] refer to Figure 3 An auxiliary buckle 5 is installed on the aforementioned shoelace extension 103. The shoelace extension 103 passes through the hole provided in the auxiliary buckle 5, so that the movable buckle 3 will not detach from the shoelace extension 103.

[0050] refer to Figure 1 Figure 3 The central post 11 on the base 1 of the aforementioned fastener is provided with teeth 111, and the side post 12 on the base 1 of the aforementioned fastener is provided with teeth 121. When tightening the shoelaces, the resistance to the shoelaces can be increased to assist in fixing the shoelaces without affecting the loosening of the shoelaces.

[0051] refer to Figure 1 The outer ring of the base 1 of the aforementioned fastener is a sewing outer ring 10, which can be used to fix the base 1 of the fastener to the shoe upper by sewing thread.

[0052] The bottom of the base 1 of the aforementioned fixing buckle is fixed to the shoe upper by adhesive.

Claims

1. A shoelace combination buckle, characterized in that: It includes: a movable buckle and a fixed buckle; the fixed buckle has a base, on which a central post is fixed vertically in the middle of the base, the function of the central post is to allow the shoelace to bend or loop; the fixed buckle includes a cover plate fixed to the top of the central post to prevent the shoelace from coming off the central post; The movable buckle has two resistance holes through which the shoelace can pass. When the shoelace is loose, its cross-sectional area is larger than that of the resistance hole. Therefore, the resistance hole provides some resistance to the forward and backward pulling of the shoelace. The resistance hole has a binding effect on the shoelace, and the shoelace cannot be pulled easily through the resistance hole. The shoelace that extends forward through the resistance hole is called the outgoing section of the shoelace. The shoelaces that come out of the eyelets need to go into the retaining buckle, so this part of the shoelace is called the insertion section. The insertion sections of the shoelaces on both sides go into the retaining buckle, go around the center post, and then pass through the resistance hole of the moving buckle. When the insertion sections of the shoelaces on both sides are pulled towards the eyelets, the shoelaces will be resisted by the resistance hole of the moving buckle. At the same time, the shoelaces will tightly wrap around the center post. Under the multiple resistances, the insertion sections of the shoelaces on both sides cannot be pulled towards the sides of the shoe. When loosening the shoelaces, pull the movable buckle forward or upward along the outstretched section of the shoelace to release it from the fixed buckle. This not only frees the outstretched section of the shoelace from the resistance hole of the movable buckle, but also releases the tension of the shoelace around the center post of the fixed buckle, allowing the shoelace to loosen. At this point, a section of shoelace can be easily pulled out from the fixed buckle at the instretched sections on both sides, thus achieving the purpose of loosening the shoelaces. When tightening shoelaces, pull the out-of-lace section forward or upward by pinching the movable buckle. The previously loosened in-lace section will be pulled towards the movable buckle. Then, move the movable buckle backward along the shoelace and close to the front center of the fixed buckle. Because the cover of the fixed buckle blocks the movable buckle, the resistance hole of the movable buckle immediately applies resistance to the shoelace. The shoelace around the center post of the fixed buckle loses its free tension and must be tightly wrapped around the center post. At this point, the shoelace is fixed, and the in-lace sections on both sides cannot be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

When loosening the shoelaces, pull the movable buckle forward or upward along the outstretched section of the shoelace to release it from the fixed buckle. This not only frees the outstretched section of the shoelace from the resistance hole of the movable buckle, but also causes the shoelace around the side post and center post of the fixed buckle to loosen. The slackness of the shoelace is released, and at this time, a section of shoelace can be easily pulled out from the fixed buckle at the position of the instretched section on both sides, thus achieving the purpose of loosening the shoelaces. When tightening shoelaces, pull the protruding section of the shoelace forward or upward by pinching the movable buckle. The previously loosened section of the protruding section will be pulled towards the movable buckle. Then, move the movable buckle backward along the shoelace and close to the front center of the fixed buckle. In this way, the shoelace coming out of the resistance hole of the movable buckle is separated to the left and right by the side post or cover plate of the fixed buckle, which is equivalent to pulling it horizontally. If the shoelace in the resistance hole of the movable buckle is pulled vertically, it is easy to pull. However, if it is pulled horizontally, the resistance will increase significantly because pulling the shoelace horizontally requires making a sharp 90-degree bend and tightly wrapping it. Any sharp bend in the shoelace will increase the resistance. At the same time, the resistance hole of the movable buckle immediately applies resistance to the shoelace. The shoelace around the side post and center post of the fixed buckle loses its free tension and must be tightly wrapped along the pre-set multiple sharp bends. At this time, the shoelace is fixed, and the protruding sections of the shoelace on both sides cannot be pulled towards the sides of the shoe upper, thus achieving the purpose of tightening the shoelaces.

At this time, a section of shoelace can be easily pulled out from the fixing buckle at the position of the shoelaces on both sides, thus loosening the shoelaces. When tightening the shoelaces, pull the shoelaces on the exit by pinching the movable buckle backward or upward. The previously loosened section of the shoelace will be pulled towards the movable buckle.
