Description

Technical Field

[0001] The utility model relates to the field of shoes and clothes, in particular to a loosening system with a lacing mechanism, and more particularly to a shoe with a lacing mechanism. Background Art

[0002] In Chinese patent application number: CN200580043345.4, a closure system for use with any of a variety of applications including clothing is disclosed, such as a footwear lacing system including a lace tied to a tightening mechanism. The lace extends along two opposing footwear closure portions through a series of guide members. Preferably, the lace and guide device have a low friction surface to facilitate the sliding of the lace along the guide members so that the lace distributes the tension evenly on the footwear member. The tightening member allows the tension of the lace to be increased. The closure system allows the user to quickly loosen the lace and inhibits unintentional and / or accidental loosening of the lace. It involves the use of a tightening mechanism located on the rear side of the shoe to achieve the closing or opening of the footwear. However, this structure requires a large force when tightening and is not suitable for automatic tightening or loosening.

[0003] Furthermore, currently, the automatic lacing system is more often set at the tongue part, such as the lacing system for footwear disclosed in Chinese patent application number: CN202080045153.1, including a sole structure, an upper attached to the sole structure, the upper including an outer side, an inner side and a tongue, and a shell arranged adjacent to the tongue. A plurality of outer eyelets are arranged along the outer side of the upper, and a plurality of inner eyelets are arranged along the inner side of the upper. A first shoelace extends from the shell through the plurality of outer eyelets, and a second shoelace extends from the shell through the plurality of inner eyelets. This arrangement can greatly reduce the force requirement.

[0004] However, for the needs of appearance, there is also a need to set the lacing system on the side of the shoe, such as Figure 7 As shown, the threading of this structure usually adopts a parallel threading method, which still generates a large force requirement. The applicant has studied this lacing system and proposed a more labor-saving structure. Utility Model Content

[0005] Therefore, in view of the above-mentioned problems, the present invention proposes a loosening system with a lacing mechanism, which solves the technical problem that the existing lacing system structure still consumes a lot of energy.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a loosening system with a lacing mechanism, comprising a first sheet body portion and a second sheet body portion, the first sheet body portion and the second sheet body portion surround a notch portion, a plurality of passages for passing are arranged on the peripheral side of the notch portion, cables are passed through the passages, a lacing mechanism for winding or releasing the cables is arranged on the first sheet body portion, when the lacing mechanism winds up the cables, the notch portion is tightened to reduce the area of ​​the notch portion, when the lacing mechanism releases the cables, the notch portion is loosened to expand the area of ​​the notch portion, the notch portion is U-shaped, one end of which forms an opening, the lacing mechanism is arranged at one end close to the opening, the channel includes at least one located on the second sheet body portion and at a position opposite to the lacing mechanism, the cables are cross-connected to the lacing mechanism after passing through the channel.

[0007] Furthermore, the cables are interlaced around the first sheet body portion and the second sheet body portion, and a guide member for realizing an X-crossing of the cables is provided near the opening of the notch portion. After passing through the guide member, the cables are cross-connected to the lacing mechanism.

[0008] Furthermore, the guide member has a first through hole and a second through hole for the cables to form an X-shaped intersection, and the first through hole and the second through hole are not connected to each other or are connected to each other.

[0009] Furthermore, the guide member is also provided with a third through hole for guiding the cable from one channel to the other channel.

[0010] Furthermore, the guide member is arranged on the first sheet body portion and / or the second sheet body portion through a flexible connecting member.

[0011] Furthermore, the guide member is made of wear-resistant material.

[0012] Furthermore, the channel is made of flexible material.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] 1. This solution places the lacing mechanism at the first body part, such as at the side of the footwear product in the footwear product, so that a large degree of force saving can be achieved. When the existing footwear products with lacing mechanisms on the side are loosened, because the lacing mechanism is located on the side, this type of threading method usually forms a side-by-side form at the lacing mechanism. When it is necessary to take off the shoes, the shoe tongue is often pulled to loosen. After pulling, the cable on one side will be pulled out to a distance at one end before driving the cable on the other side. In this existing method, the cables cannot be forced to drive the spool of the lacing mechanism to rotate at the same time, but only rely on the cable on one side to pull the winding shaft to rotate, which will produce a large force. The longer the cable is wound, the greater the force will be after pulling, and it may even cause the cable on the other side of the winding shaft to be squeezed after pulling out a distance at one end, resulting in a stuck phenomenon. This solution changes the lacing line to avoid the effect of only one side of the rope being stressed, and achieves the effect of smooth line output when the double-sided rope is stressed at the same time.

[0015] 2. The notch is set to be U-shaped, with one end forming an opening, and the lacing mechanism is set at the end close to the opening, so that a better loosening effect can be achieved and a better labor-saving effect can be achieved. In addition, a channel is set specifically to achieve a better cable winding effect.

[0016] 3. The setting of the guide piece can make the winding of the wire form an X-cross at the end, so that the matching angle between the cable and the lacing mechanism can be better, and the two ends of the cable entering the lacing mechanism are basically parallel, which has a better labor-saving effect.

[0017] 4. The setting of the guide member can make the cable enter and exit more smoothly, and can also effectively reduce friction, and achieve smoother loosening and tightening. Among them, the first through hole and the second through hole are not connected to each other or connected to each other, which can be achieved by setting up upper and lower offset holes. The third through hole can achieve guidance when the cable is passed through, and this through hole can also be not set. Among them, the guide member can be set on the first sheet body part and / or the second sheet body part through a flexible connector, so as to achieve relative stability of the position, thereby achieving smooth release or contraction of force, thereby achieving the purpose of saving effort. Of course, the guide member can also be set at the tongue part. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0028] refer to Figure 1 , Figure 2 The present embodiment provides a release system with a lacing mechanism, comprising a first sheet body portion 1 and a second sheet body portion 2, wherein the first sheet body portion 1 and the second sheet body portion 2 surround a notch portion 3, wherein a plurality of channels 4 for passing are arranged on the peripheral side of the notch portion 3, wherein cables 5 are passed through the channels 4, and a lacing mechanism 6 for winding or releasing the cables 5 is arranged on the first sheet body portion 1, wherein when the lacing mechanism 6 winds up the cables 5, the notch portion 3 is tightened to reduce the area of ​​the notch portion 3, and when the lacing mechanism 6 releases the cables 5, the notch portion 3 is loosened to expand the area of ​​the notch portion 3. The notch portion 3 is U-shaped, and an opening 31 is formed at one end thereof, and the lacing mechanism 6 is arranged at one end close to the opening 31. The channels 4 include at least one located on the second sheet body portion 2 and at a position opposite to the lacing mechanism 6, and the cables 5 are crossed and connected to the lacing mechanism 6 after passing through the channels 4. The channels 4 are made of a flexible material, such as fabric.

[0029] The above-mentioned lacing mechanism 6 can adopt a clutch winch device disclosed in Chinese patent application number: CN202211246428.5, or a lacing device disclosed in CN202311388694.6, and other products with similar functions can also be used.

[0030] The first sheet body 1 and the second sheet body 2 can be integrally formed or separately formed. When they are separately formed, they can be fixedly connected or detachably connected by sewing, gluing, etc. Figure 2 , which is applied to footwear products, and in practical applications, can also be applied to clothing products, such as clothes, pants, etc. When used as shoes, the first body portion 1 and the second body portion 2 form the upper and the shoe upper, the notch portion 3 is located at the tongue, and the cable 5 constitutes the shoelace.

[0031] like Figure 1 As shown, the cable 5 is actually one line, and the cable 5 is divided into a blue double-dotted line and a green dotted line to indicate the direction of the cable 5. The cables 5 at both ends are in an X-cross state when entering the lacing mechanism 6, which is a preferred choice and can achieve better loosening and tightening. Of course, it is also possible not to set it in an X-cross state.

[0032] This solution places the lacing mechanism at the first body part, such as at the side of the footwear product in the footwear product, so that a large degree of force saving can be achieved. When the existing footwear products with lacing mechanisms on the side are loosened, because the lacing mechanism is located on the side, this type of threading method usually forms a side-by-side form at the lacing mechanism. When it is necessary to take off the shoes, the shoe tongue is often pulled to loosen. After pulling, the cable on one side will be pulled out to a distance at one end before driving the cable on the other side. In this existing method, the cables cannot be forced to drive the spool of the lacing mechanism to rotate at the same time, but only rely on the cable on one side to pull the winding shaft to rotate, which will produce a large force. The longer the cable is wound, the greater the force will be after pulling, and it may even cause the cable on the other side of the winding shaft to be squeezed after pulling out a distance at one end, resulting in a stuck phenomenon. This solution changes the lacing line to avoid the effect of only one side of the rope being stressed, and achieves the effect of smooth line output when the double-sided rope is stressed at the same time.

[0033] The notch is set in a U shape, with an opening 31 formed at one end, and the lacing mechanism 6 is arranged at one end close to the opening 31, so that a better loosening effect can be achieved and a better labor-saving effect can be achieved. In addition, a channel 4 is specifically set to achieve a better winding effect of the cable 5.

[0034] Refer to Figure 3-6, this embodiment provides a release system with a lacing mechanism 6 based on the same inventive concept, which differs from the first embodiment in that a guide member 7 is added. Specifically, the cables 5 are staggered around the first sheet body 1 and the second sheet body 2, and the notch 3 is provided with a guide member 7 near the opening 31 for realizing the X-shaped cross of the cables 5. The cables 5 are cross-connected to the lacing mechanism 6 after passing through the guide member 7. The guide member 7 has a first through hole 71 and a second through hole 72 for the cables 5 to form an X-shaped cross. The first through hole 71 and the second through hole 72 are not connected to each other or are connected to each other. Preferably, the first through hole 71 and the second through hole 72 are different from each other, which is a better choice. The guide member 7 is also provided with a third through hole 73 for the cables 5 to pass from one channel 4 to another channel 4 for guidance. The channel 4 includes at least one located on the second sheet body 2 and located at a position opposite to the lacing mechanism 6. The cables 5 pass through the guide member 7 after passing through the channel 4, and then cross-connected to the lacing mechanism 6. The guide member 7 is arranged on the first sheet body portion 1 and / or the second sheet body portion 2 via a flexible connecting member 74. The guide member 7 is made of a wear-resistant material.

[0035] like Figure 3 As shown, the cable 5 is actually one line, and the cable 5 is divided into a blue double-dotted line and a green dotted line to indicate the direction of the cable 5. In addition, in the guide member 7, the first through hole 71 is a red dotted line, the second through hole 72 is a pink dotted line, and the third through hole 73 is a purple dotted line.

[0036] like Figure 5 As shown, in the guide member 7, the third through hole 73 may not be provided.

[0037] The setting of the guide member 7 can make the winding of the wire form an X-cross at the end, so that the matching angle between the cable 5 and the lacing mechanism 6 can be better, and the two ends of the cable 5 entering the lacing mechanism 6 are basically parallel, which has a better labor-saving effect.

[0038] The setting of the guide member 7 can make the cable 5 enter and exit more smoothly, and can also effectively reduce friction, and achieve smoother loosening and tightening. Among them, the first through hole 71 and the second through hole 72 are not connected to each other or are connected to each other, which can be achieved by setting up upper and lower offset holes. The third through hole 73 can achieve guidance when the cable 5 is passed through, and this through hole can also be not set. Among them, the guide member 7 can be set on the first sheet body part 1 and / or the second sheet body part 2 through the flexible connecting member 74, so as to achieve relative stability of the position, thereby achieving smooth release or contraction of force, thereby achieving the purpose of saving effort. Of course, the guide member 7 can also be set at the tongue part.

[0039] Based on the above method, the test is as follows:

[0040] The common rotating fasteners on the market have a winding capacity of about 20CM on one side, so the test condition is set to a 20CM length of pre-wound wire for the rotating fastener. When used on shoes, the larger the size, the longer the rope that needs to be pulled out when taking off the shoes. The length of about 5cm that needs to be pulled out when taking off children's shoes and the length of about 10cm that needs to be pulled out when taking off adult shoes are cut off to compare the pulling force of the single and double sides of the rope.

[0041] Table 1 shows the tensile test of the cable length pulled out when loosening similar products on the market:

[0042]

[0043] Table 2 shows the tensile test of the cable length when the product is loosened in different implementation states:

[0044]

[0045] Comparing Table 1 and Table 2, it can be clearly seen that this product has a great improvement in force saving. In normal use, similar products can usually only achieve unilateral pull rope release, while this solution can achieve relatively standard bilateral pull rope release by adjusting the setting method of the lacing mechanism.

[0046] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
