Description

[0001] This application claims the priority of the patent application with the application number 202323082226.4 and the title "A Lace Guide and a Lace System Comprising the Same", and the filing date of November 15, 2023. Technical Field

[0002] The utility model relates to the field of item laces, and particularly to a lace guide and a lace system comprising the same. Background Art

[0003] Conventional items with laces achieve the function of releasing or contracting the opening of the item by tightening or loosening the laces. For example, shoes with laces can be put on and taken off and the tightness of the shoes can be adjusted by operating the laces. The shoes also include a lace guide, which guides the lace to form a lace path on the shoe surface, so as to tighten the shoe in different areas and balance the force on each area of the shoe. At the same time, the lace guide can also fix the lace to prevent the lace from being randomly distributed on the shoe surface and causing potential safety hazards.

[0004] Currently, in different situations where the user needs to adjust the lace, the lace guide is required to have a certain amount of slack space to enable frequent and slight tightening or loosening of the lace. For example, for a person who sits for a long time, due to sitting for a long time, the feet will swell, so the lace needs to have a certain amount of slack space to make the shoes slightly loose and prevent the feet from being in a tightened state all the time; for another example, in order to ensure that the shoes are stable and do not come off during running, the lace will be tied firmly, but due to the repeated bending of the tongue of the shoe at the ankle for many times in a short time, the lace also needs to have a certain amount of slack space. There are many such situations in reality. However, the existing lace guides have no telescopic deformation or elastic deformation, or have a complex structure, resulting in almost no slack space once the lace is tightened, unless the shoelace is loosened by hand, which is cumbersome and time-consuming.

[0005] Therefore, a lace guide with a certain amount of telescopic deformation or elastic deformation is needed to meet the requirements. Summary of the Utility Model

[0006] The utility model provides a lace guide to solve at least one of the problems in the prior art to a certain extent.

[0007] A first aspect of the utility model provides a lace guide for coupling with an item and passing through a lace, comprising a fixing member, a connecting member and a threading member. The threading member has a hollow structure to form a threading channel for the lace to pass through, and the threading member at least includes a lace inlet end and a lace outlet end; wherein,

[0008] The fixing member is used for coupling with the item;

[0009] The first end of the connecting member is connected to the fixing member, the second end of the connecting member is connected to the threading member, and the lace inlet end and the lace outlet end of the threading member protrude in different directions away from the second end of the connecting member; wherein,

[0010] When the threading member is not subject to an external force and is in a natural state, the lace inlet end and / or the lace outlet end of the threading member is located at a first position;

[0011] When the threading member is subject to an external force, the lace inlet end and / or the lace outlet end of the threading member moves to a second position or is in a second position;

[0012] And the distances from the first position and the second position to the fixing member are not equal.

[0013] The lace guiding member of the present utility model can achieve elastic deformation under a small acting force and meet the fine-tuning function in actual use.

[0014] In the present utility model, the "article" includes footwear, bags, clothes, etc. The "first" and "second" are only used to represent two different parts. The "lace inlet end" refers to the inlet where the lace first enters the entire lace guiding member, and the "lace outlet end" refers to the outlet where the lace exits the entire lace guiding member.

[0015] Preferably, the threading member is of an integral structure or includes two or more threading segments.

[0016] When the threading member is of an integral structure, the threading channel is an integral channel; when the threading member includes two or more threading segments, the two or more threading segments may be connected to each other or separated from each other, but the threading channel includes two or more mutually separated channel segments. For example: two or more threading segments may be connected via the outer wall of one side of the threading channel, but the threading channel is composed of disconnected channel segments.

[0017] Preferably, the two or more threading segments at least include a lace introduction segment and a lace export segment. The lace introduction segment and the lace export segment protrude and extend in different directions relative to the second end of the connecting member, and the lace inlet end is arranged on the lace introduction segment, and the lace outlet end is arranged on the lace export segment.

[0018] Preferably, one end of the lace introduction segment opposite to the lace inlet end is connected to the second end of the connecting member; one end of the lace export segment opposite to the lace outlet end is connected to the second end of the connecting member.

[0019] Preferably, the threading member further includes a lace guiding section disposed between the lace introducing section and the lace discharging section and separated from the lace introducing section and the lace discharging section.

[0020] Preferably, the threading channel is arc-shaped, and the lace inlet end and the lace outlet end are two free ends of the arc or inclined toward the center of the arc.

[0021] When the threading member is subjected to the tension force from the lace, both ends of the threading channel move toward the inside of the arc. This structural design enables the lace guiding member to have the strongest fine-tuning ability in response to the tension of the lace. Of course, the center of the arc of the threading member having an arc-shaped threading channel may be located on the side where the fixing member is located, or may be located on the opposite side of the side where the fixing member is located. Therefore, when the threading member is subjected to an external force, the lace inlet end and the lace outlet end may move toward the direction close to the fixing member, or may move away from the fixing member, but whether it is close to or away from the fixing member, it moves toward the inside of the arc. Such a design enables the lace guiding member to have an excellent fine-tuning function for tightness.

[0022] Preferably, the threading member is connected to the fixing member through at least one connecting member.

[0023] Specifically, the threading channel can be connected to the fixing member through one connecting member or multiple connecting members. For example, for a threading member including more than two threading segments, the lace introducing section and the lace discharging section can be respectively connected to the fixing member through an independent connecting member. Of course, the integral-structured threading member can be connected to the fixing member through one connecting member or multiple connecting members. Similarly, a threading member including more than two mutually separated parts can also be connected to the fixing member through one connecting member or multiple connecting members. Among them, each independent threading member part can be connected to the fixing member through one connecting member, or two or more threading member parts can be separated from the fixing member through one connecting member.

[0024] Preferably, the threading member or each threading segment is separately formed and then connected to the fixing member through a connecting member.

[0025] Preferably, the threading member or each threading segment is integrally formed with the connecting member and then connected to the fixing member.

[0026] Preferably, the threading member, the connecting member, and the fixing member are of an integrally formed structure.

[0027] In the present utility model, the connection modes of the fixing member, the connecting member, and the threading member can be selected from one or a combination of multiple connection modes.

[0028] Preferably, the thread threading member is made of an elastic material or is a structure capable of elastic deformation.

[0029] Preferably, the connecting member is made of an elastic material or is a structure capable of elastic deformation.

[0030] In the present utility model, when the thread threading member receives an external force, the lace inlet end and / or the lace outlet end can generate displacement between a first position and a second position due to the elastic deformation of the thread threading member and / or the connecting member. Therefore, whether the thread threading member and / or the connecting member is made of an elastic material or is made into a structure capable of elastic deformation, the purpose is to enhance the deformation ability of the thread threading member and / or the connecting member, so as to ensure that at least the thread threading member can generate displacement between the first position and the second position under the condition of receiving a small external force, achieving the purpose of use.

[0031] Preferably, an observation hole is provided on the thread threading member.

[0032] Preferably, when the thread threading member is subjected to an external tensile force, the lace inlet end and / or the lace outlet end move towards or away from the fixing member.

[0033] On the other hand, the present utility model provides a lacing system, which includes one or more lacing guides as described in the present utility model, as well as a lacing device and a lace; the free end of the lace enters the lacing guide through the lace inlet end and is guided through the thread threading channel and then exits through the lace outlet end, and finally is coupled to the lacing device, and the lacing device can operably tighten or release the lace.

[0034] Preferably, a plurality of the lacing guides are arranged on the article, and the thread threading members of the plurality of lacing guides are arranged opposite to and / or away from each other.

[0035] The "arranged opposite to and / or away from each other" means that the same components of two lacing guides are arranged opposite to or away from each other. For example, when two lacing guides are arranged on the shoe upper and are respectively arranged on both sides of the tongue, and the thread threading members of the two lacing guides are both arranged facing the center of the tongue, it is that the two lacing guides are arranged opposite to each other; if one thread threading member of one lacing guide is arranged facing the center of the tongue and one is arranged away from the center of the tongue (the fixing member is arranged facing the center of the tongue), it is that the two lacing guides are arranged away from each other.

[0036] Preferably, the lacing device includes a rotary cap, a housing, and a wire reel. The rotary cap is rotatably disposed on the housing. The wire reel is supported by the housing and is rotatable relative to the housing. The wire reel is configured to wind up the lace when rotating in the tightening direction and to release the lace when rotating in the loosening direction. The lacing device is provided with a mode switching mechanism to realize the switching of the working modes of winding up and releasing the lace by the wire reel.

[0037] The beneficial effects of the present utility model are embodied in:

[0038] 1. A lace guiding member is provided. When the threading member is subjected to an external force, the lace inlet end and / or the lace outlet end actively switch between a first position and a second position, and the lace inlet end and the lace outlet end of the threading member can have a greater displacement change than other segments on the threading member. Compared with the lace guiding member in which the whole threading member has a displacement change, the lace guiding member provided by the present utility model is more conducive to realizing the fine adjustment function of the lace path;

[0039] 2. When the lace guiding member is applied to articles such as shoes, there is no need to manually adjust the tightness of the lace. The lace guiding member will automatically adjust according to the change of the external force, liberating both hands and improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Embodiment 1

[0055] This embodiment provides a lace guide member 1, as Figure 1 shown, for coupling with an article and passing through a lace, including a fixing member 11, a connecting member 12 and a threading member 13. The fixing member 11 is used for coupling with the article. The threading member 13 is connected to the fixing member 11 through the connecting member 12. The threading member 13 is a hollow structure and forms a threading channel 131 for the lace to pass through. The threading member includes at least a lace inlet end 1321 and a lace outlet end 1331. Among them, the fixing member 11 is used for coupling with the article. The first end 12a of the connecting member 12 is connected to the fixing member 11, the second end 12b of the connecting member 12 is connected to the threading member 13, and the lace inlet end 1321 and the lace outlet end 1331 of the threading member protrude in different directions away from the second end 12b of the connecting member 12. In this embodiment, the threading member 13, the connecting member 12 and the fixing member 11 are integrally formed. The threading member 13 and the connecting member 12 are both made of elastic materials. When the threading member 13 is not subjected to an external force and is in a natural state, as Figure 2As shown, the lace inlet end 1321 and / or the lace outlet end 1331 of the thread-passing member are located at the first position A, i.e., the initial position; when an external force is applied to the thread-passing member, the lace inlet end 1321 and / or the lace outlet end 1331 of the thread-passing member move to the second position B away from the fixing member 11, or are in the second position B; and the distances from the first position A and the second position B to the fixing member 11 are not equal. Since both the thread-passing member 13 and the connecting member 12 are made of elastic materials and undergo elastic deformation under the action of an external force, the lace inlet end 1321 and / or the lace outlet end 1331 of the thread-passing member 13 move away from the first position A (the initial position) and shift to the second position B, thereby driving the lace passing through the thread-passing channel 132 to change its position and achieving the purpose of fine adjustment. As Figure 2 shown, when an external force is applied to the thread-passing member 13 through the lace, the thread-passing member 13 moves from the first position A to the second position B, and both the thread-passing member 13 and the connecting member 12 undergo elastic deformation.

[0056] Further, the thread-passing member may be an integral structure or may include a plurality of thread-passing segments. In a preferred embodiment, as Figure 1 shown, the thread-passing member 13 includes a lace-introducing section 132 and a lace-exiting section 133 that are separated from each other. The thread-passing channel 131 also includes two separated channel sections. The lace-introducing section 132 and the lace-exiting section 133 protrude and extend in different directions relative to the second end 12b of the connecting member 12. The lace inlet end 1321 is provided on the lace-introducing section 132, and the lace outlet end 1331 is provided on the lace-exiting section 133. The lace-introducing section 132 and the lace-exiting section 133 are respectively connected to the fixing member 11 through a connecting member (121, 122). The end of the lace-introducing section 132 opposite to the lace inlet end 1321 is connected to the second end 12b of the connecting member 121; the end of the lace-exiting section 133 opposite to the lace outlet end 1331 is connected to the second end 12b of the connecting member 122. In other preferred embodiments, as Figure 3 shown, the lace-introducing section and the lace-exiting section may also be connected to the fixing member 11 through a connecting member 12. The end of the lace-introducing section opposite to the lace inlet end 1321 is connected to the first end 12b1 of the second end 12b of the connecting member 12; the end of the lace-exiting section opposite to the lace outlet end 1331 is connected to the second end 12b2 of the second end 12b of the connecting member 12. Further preferably, as Figure 3 shown, the thread-passing channel 131 is an arc L, and the lace inlet end 1321 and the lace outlet end 1331 are two free ends of the arc L or are inclined towards the center of the arc.

[0057] Furthermore, in another embodiment provided by the present utility model, as Figure 4 shown, the lace guiding member 2 includes a fixing member 21, a connecting member 22 and a threading member 23. The difference from the lace guiding member 1 is that the threading member 23 includes separated threading segments. In addition to the lace inlet segment 232 and the lace outlet segment 233, it further includes a lace guiding segment 234, which is arranged between the lace inlet segment 232 and the lace outlet segment 233 and is separated from the lace inlet segment and the lace outlet segment; the threading channel 231 also includes three separated channel sections. Specifically, referring to Figure 4 , the threading channel 231 of the threading member 23 is configured as an arc, and the two ends of the arc-shaped channel are a lace inlet end 2321 and a lace outlet end 2331 and are inclined towards the center of the arc. Referring to Figure 4 shown, when the lace sequentially passes through the channel section of the lace inlet segment 232 from the lace inlet end 2321, enters the channel of the lace guiding segment 234, then passes through the channel of the lace outlet segment 233 and exits from the lace outlet end 2331, and the two free ends of the lace are tightened. Since the threading member is arranged in an arc as a whole, that is, the extending directions of the lace inlet segment 232, the lace guiding segment 234, and the lace outlet segment 233 are arcs with the same curvature. If the lace inlet end 2321 and the lace outlet end 2331 are simultaneously stressed, and the stress direction is towards the center of the arc, the arc-shaped structure of the threading member 23 is consistent with the direction of stress deformation, enabling the threading member 23 to adapt to displacement changes under a smaller external force, achieving the purpose of fine adjustment. In other embodiments, multiple lace guiding segments 234 can also be provided. With this structural design of the threading member, since the lace inlet segment 232 and the lace outlet segment 233 are arranged on both sides of the fixing member 21, when fine-tuning under an external force, the force is more evenly distributed on the surface of the article, and the guiding ability for the lace routing path is stronger. It will not cause the fine-tuning function to be concentrated in some areas due to the concentrated positions of the lace inlet segment 232 and the lace outlet segment 233, reducing the experience. The "extending direction" described in the present utility model refers to the projection of an object on a plane parallel to the central axis of the object. On this plane, the extending direction or trend of the vast majority of the projection points is allowed to have small deformations and protrusions in the middle, but the overall extending direction remains unchanged. For example, the main extending direction of a rectangle is the length direction. It can be understood that the extending direction of each threading segment is the long axis direction of each threading segment.

[0058] As Figure 4As shown, the three wire threading segments 232, 233, and 234 of the wire threading member 23 are all connected to the fixed member 21 through a connecting member 22; the connection points are distributed at both ends and the middle position of the second end of the connecting member 22, where the lace leading-in segment 232 and the lace guiding segment 234 are located at both ends, which is more conducive to the deformation adjustment of the lace inlet end and the lace outlet end.

[0059] In the embodiments provided by the present utility model, different wire threading segments of the wire threading member are connected to the fixed member through multiple connecting members or through one connecting member. Multiple connecting members are respectively connected to multiple wire threading segments. In practical applications, the deformation ability of each connecting member can be fully utilized. If multiple wire threading segments are only connected through one connecting member, in order to ensure the connection strength and connection safety, it is necessary to increase the relevant dimensions of the connecting member (such as thickness, width, etc.), and then the deformation ability of the connecting member will be correspondingly reduced. Therefore, it is selected to connect multiple wire threading segments of the wire threading member through multiple connecting members. On the one hand, it increases the connection strength and safety, and on the other hand, it increases the deformation ability. And when one connecting member and / or one wire threading segment fails and cannot be used, other connecting members and wire threading segments can be used alone without being affected. As Figure 3 and Figure 4 shown in the lace guiding member, the lace leading-in segment and the lace leading-out segment of the wire threading member are connected to both ends of the second end of the same connecting member and protrude and extend in different directions relative to both ends. The deformation control ability of both ends of the second end of the connecting member is also very strong, and it has stronger deformation adjustment ability compared with other positions of the second end.

[0060] In other embodiments, multiple wire threading segments of the wire threading member are separately formed and then connected to the fixed member through a connecting member.

[0061] In other embodiments, multiple wire threading segments of the wire threading member are integrally formed and then connected to the fixed member through a connecting member.

[0062] In other embodiments, the wire threading member is integrally formed with the connecting member and then connected to the fixed member.

[0063] In other embodiments, the connection mode of the fixed member, the connecting member, and the wire threading member can be selected from one or a combination of multiple connection modes above.

[0064] In other embodiments, the wire threading member is a structure that can produce elastic deformation.

[0065] In other embodiments, the connecting member is a structure that can produce elastic deformation.

[0066] In other embodiments, one or both of the threading member and the connecting member are selected to be made of an elastic material to form a structure that can undergo elastic deformation. The deformation of the threading member is superimposed on the deformation of the connecting member, enabling the threading member to undergo displacement deformation when subjected to a small external force.

[0067] In other embodiments, an observation hole (not shown) is provided on the threading member.

[0068] In other embodiments, when the threading member is subjected to an external tensile force, the threading member moves towards the fixed member.

[0069] In other embodiments, when the threading member is subjected to an external tensile force, the threading member moves away from the fixed member.

[0070] When the threading member is subjected to an external tensile force, if the force application direction is towards the fixed member, the threading member moves towards the fixed member; if the force application direction is away from the fixed member, the threading member moves away from the fixed member. The moving direction of the threading member is determined by the direction of the force applied.

[0071] Embodiment 2

[0072] This embodiment is a lacing system, which includes the lacing guide 1 in Embodiment 1, as well as a lacing device 3 and a lace 4. The free end of the lace 4 passes through the lace inlet end of the lacing guide 1 and exits from the lace outlet end, and finally couples with the lacing device 3. The lacing device 3 can operably tighten or release the lace. The lacing device 3 includes a rotary cap, a housing, and a spool. The rotary cap is rotatably disposed on the housing. The spool is supported by the housing and can rotate relative to the housing. The spool is configured to wind up the lace when rotating in the tightening direction and release the lace when rotating in the loosening direction. The lacing device is provided with a gear shifting mechanism to realize the action switching of the spool for tightening and loosening the lace. The structure of the spool and its connection manner with the rotary cap can refer to the content of the patent document CN202321495677.8.

[0073] In other preferred embodiments, a plurality of lacing guides are arranged on the article, and the threading members of the plurality of lacing guides are arranged opposite to and / or away from each other. For example Figure 5 The shown lacing system includes two lacing guides 1 provided by the present invention and four ordinary guides 5. Among them, the two lacing guides 1 are arranged opposite to each other, and the other lacing guides 5 are ordinary guides, such as braided tape guides. Other preferably, all the plurality of lacing guides in the lacing system can be the lacing guides 1 in Embodiment 1 or all be the lacing guides 2, or a combination of the lacing guides 1 and 2 in Embodiment 1, or a combination of other lacing guides that meet the lacing guiding function and the lacing guides provided by the present invention, where there is at least one lacing guide provided by the present invention in the lacing system.
