Description

Technical Field

[0001] This utility model relates to the field of daily living devices, and in particular to a strapping device and a wearable article including the above-mentioned strapping device. Background Technology

[0002] Shoelaces are usually secured by crisscrossing and knotting, but this method is rather cumbersome and the laces are prone to coming undone during walking or exercise, causing inconvenience.

[0003] To address these issues, lacing devices for adjusting shoelace tightness have emerged on the market. Traditional lacing devices require mounting holes in the shoe's upper to match a mounting bracket. The bracket is then used to secure the lacing device to the shoe. In this case, the shape of the mounting hole must perfectly match the bracket, and any irregularities or burrs on the hole's edges must be trimmed to prevent them from protruding and affecting the shoe's appearance. Utility Model Content

[0004] Therefore, it is necessary to provide a strapping device that can solve the above-mentioned problems. Furthermore, it is also necessary to provide a wearable article that includes the aforementioned strapping device.

[0005] A lacing device for adjusting lacing on a wearable article, the wearable article having an mounting area, the mounting area including a fabric layer having mounting through holes;

[0006] The strapping device includes a fixing base, which can be fixed to a wearable item independently of other parts of the strapping device; the fixing base includes a columnar body, and the outer side of the columnar body is provided with an upper flange, a receiving groove, a lower boss and a mounting flange from top to bottom, and the receiving groove is formed between the upper flange and the lower boss; the columnar body has an inner cavity, and the side wall of the lower boss is provided with a threading hole communicating with the inner cavity;

[0007] The upper flange of the mounting base passes through the mounting through hole and protrudes outside the fabric layer. The edge of the mounting through hole is accommodated in the receiving groove, and the mounting flange is located below the fabric layer.

[0008] In one embodiment, both the lower boss and the threading hole are located below the fabric layer.

[0009] In one embodiment, the opening end of the inner cavity of the fixing seat is close to the upper flange.

[0010] In one embodiment, the end of the mounting base with the upper flange extends through the mounting through hole from bottom to top.

[0011] In one embodiment, the area of ​​the fabric layer near the mounting through hole is fixedly connected to the mounting flange.

[0012] In one embodiment, the mounting flange includes a fixed area and a dynamic area. The mounting flange is fixedly connected to the fabric layer through the fixed area. A stitching area is formed between the dynamic area and the fabric layer, allowing the tie to pass through. The stitching area, the threading hole, and the inner cavity are sequentially connected. The "dynamic area" is generally the area aligned with the threading hole, or the area radiated by the threading hole. The tie can slide through this area, and it is not fixed to the fabric layer using a dedicated fixing method; instead, its edge is positioned by the fixed area. Therefore, it is called the "dynamic area."

[0013] Preferably, the fixing area is fixed to the fabric layer by means of sewing, adhesive or other methods.

[0014] In one embodiment, the mounting flange is a complete ring or a notched ring; the shape of the mounting through hole can be regular or irregular.

[0015] In one embodiment, the orthographic projection of the mounting through hole is within the edge range of the orthographic projection of the upper flange. The orthographic projection refers to the projection along the central axis of the mounting base. This design ensures that the edge of the mounting through hole can be shielded by the upper flange.

[0016] In one embodiment, when the upper flange is circular, its outer diameter is larger than the diameter of the mounting through hole or its circumscribed circle. When the mounting through hole is a regular circle, its diameter is the diameter of the circular through hole; when the mounting through hole is an irregular shape, its diameter is the diameter of the circumscribed circle of that irregular shape. When the outer diameter of the upper flange is larger than the diameter of the mounting through hole or its circumscribed circle, the upper flange can block the mounting through hole, so regardless of whether the shape of the mounting through hole is regular or whether there are burrs on the edges, it will be hidden and will not affect the aesthetic appearance.

[0017] Preferably, there are one or more threading holes. "More than" means two or more, including two.

[0018] In one embodiment, the threading hole is a hole formed in the side wall of the lower boss.

[0019] In one embodiment, the outer side wall of the lower boss is provided with a lug structure, and the through hole is a channel or hole that passes through the side wall of the lower boss and the lug structure.

[0020] In one embodiment, there are two threading holes, and the included angle between the two threading holes is any angle within the range of 30° to 180°. The included angle between the two threading holes refers to the included angle of the central axis of the threading holes. Preferably, the central axis of the threading holes passes through the center of the fixing base.

[0021] Preferably, when the included angle between the two wire holes is 180°, the mounting flange is a complete circle; when the included angle between the two wire holes is 30° to 150°, the mounting flange is a notched annulus, and the notch is located within the dynamic zone.

[0022] In one embodiment, the mounting through hole is circular, the columnar body is cylindrical, and the upper flange, the receiving groove, the lower boss, and the mounting flange are all annular.

[0023] In one embodiment, the tying device further includes a housing disposed within the inner cavity and a spool rotatably disposed within the housing for winding the tying.

[0024] The housing is provided with a tie hole that communicates with the threading hole, and the spool communicates with the threading hole through the tie hole.

[0025] In this application, the ties can extend through the threading hole of the fixing seat and pass through the ties hole of the housing to enter the housing and couple with the spool.

[0026] In one embodiment, the cavity wall of the inner cavity is provided with a snap-fit ​​portion, and the outer side of the housing is provided with a snap-fit ​​mating portion that snaps into the snap-fit ​​portion.

[0027] In one embodiment, the tying device further includes a cap rotatably disposed on the housing and a backstop assembly. The tying device has a winding tying mode and a loosening tying mode. The backstop assembly is used to prevent the cap and the spool from rotating in the loosening direction in the winding tying mode. The backstop assembly includes at least a first backstop member and a second backstop member, wherein the cap is provided with the first backstop member and the housing is provided with the second backstop member.

[0028] Preferably, the first anti-reverse component is a ratchet tooth, and the second anti-reverse component is a pawl.

[0029] Preferably, the first anti-reverse component is a toothed groove, the second anti-reverse component is an offset component, and the anti-reverse assembly further includes a third anti-reverse component, which is a stop block disposed on the housing.

[0030] This application also provides a wearable article including a tie and the aforementioned tie device, wherein the tie is concealed beneath the fabric layer.

[0031] In one embodiment, the wearable item is a shoe, the lacing is a shoelace, and the lacing device is installed on the tongue, heel, or upper of the shoe.

[0032] Preferably, the lacing device is mounted on the side of the shoe.

[0033] When this tie-on device is installed onto the wearable item, one end of the upper flange on the fixing base passes through the mounting through-hole in the fabric layer from bottom to top, or the other end of the mounting flange is squeezed into the mounting through-hole from top to bottom, and then the mounting flange is fixedly connected to the fabric layer through the fixing area. Compared with the traditional solution, when this tie-on device is installed onto the wearable item, the edge of the mounting through-hole is accommodated in the receiving groove, thereby hiding the edge of the mounting through-hole. The shape of the mounting through-hole does not need to be strictly matched with the fixing base, and any irregular parts or burrs on the edge of the mounting through-hole are hidden in the receiving groove and covered by the upper flange, thus avoiding affecting the aesthetics. This structural design simplifies the drilling process of the mounting through-hole, eliminating the need for precise hole matching and omitting the burr removal process, making the forming or preparation cost of the mounting area lower and simpler.

[0034] Furthermore, the edge of the mounting through hole is accommodated in the receiving groove, which also serves to position the fabric layer. The edge of the mounting through hole is confined within the receiving groove, preventing it from moving freely in the axial direction and from being tightly attached to the mounting flange. This provides space between the fabric layer and the mounting flange, facilitating the smooth routing of the straps on wearable items.

[0035] Preferably, in this embodiment, the threading hole is located on the side wall of the lower boss. Both the lower boss and the threading hole are located below the fabric layer, allowing the straps of the wearable item to be concealed under the fabric layer and then pass through the threading hole to reach the inner cavity of the fixing base, thereby achieving the concealment of the straps of the wearable item. The straps are hidden below the fabric layer, meaning that the straps are concealed below the fabric layer both when they emerge from the lacing device and before they are inserted into the lacing device. This design can meet the aesthetic needs of some user groups.

[0036] Preferably, the dynamic area corresponds to the thread hole and a stitching area is formed between the dynamic area and the fabric layer. The stitching area, the thread hole and the inner cavity are connected in sequence, thereby forming a channel for the ties of a wearable item.

[0037] Preferably, the outer diameter of the upper flange is larger than the diameter of the mounting through hole or its circumscribed circle diameter, so that the edge of the mounting through hole can be better concealed.

[0038] Preferably, the housing is provided with a tie hole communicating with the threading hole, and the spool communicates with the threading hole through the tie hole. In this case, after the tie passes through the threading hole to the inner cavity of the fixing base, it can pass through the tie hole and couple with the spool.

[0039] Preferably, the inner cavity wall is provided with a snap-fit ​​portion, and the outer side of the housing is provided with a snap-fit ​​mating portion that snaps into the snap-fit ​​portion. This structural arrangement allows for a detachable connection between the housing and the fixing seat, facilitating replacement of the strapping device after damage. Therefore, the fixing seat can be fixed to wearable items independently of other parts of the strapping device; the other parts are detachably connected via the snap-fit ​​structure between the housing and the fixing seat.

[0070] Combination Figures 1 to 6The present invention discloses a strap device 100 according to one embodiment, which is used to adjust the straps on a wearable article. The wearable article has an installation area, which includes a fabric layer 300 and an installation through hole 301.

[0071] The lacing device 100 includes a mounting base 120, which can be secured to a wearable item independently of other parts of the lacing device.

[0072] Reference Figure 1 and Figure 3 The fixing base 120 includes a columnar body 121, which is preferably cylindrical. The outer side of the columnar body 121 is provided with an upper flange 122, a receiving groove 123, a lower boss 124 and a mounting flange 125 from top to bottom. In this embodiment, the upper flange 122, the receiving groove 123, the lower boss 124 and the mounting flange 125 are all annular, and the receiving groove 123 is formed between the upper flange 122 and the lower boss 124.

[0073] Continue to refer to Figure 1 and Figure 3 The columnar body 121 has an inner cavity 126, with the opening end of the inner cavity 126 near one end of the upper flange 122. The side wall of the lower boss 124 is provided with a threading hole 127 communicating with the inner cavity 126. Both the lower boss 124 and the threading hole 127 are located below the fabric layer 300, allowing the straps of wearable items to be hidden under the fabric layer 300 and reach the inner cavity 126 of the fixing base 120 through the threading hole 127, thus achieving the concealment of the straps of the wearable items. In this embodiment, the threading hole 127 is a hole formed in the side wall of the lower boss to penetrate the inner and outer parts of the inner cavity of the fixing base.

[0074] The mounting base 120 has an upper flange 122 at one end that can pass through the mounting through hole 301 from bottom to top. The upper flange 122 protrudes beyond the fabric layer 300, and the edge of the mounting through hole 301 is accommodated in the receiving groove 123. The mounting flange 125 is located below the fabric layer 300, and the area of ​​the fabric layer 300 near the mounting through hole 301 is fixedly connected to the mounting flange 125, or in other words, the area near the mounting flange adjacent to the lower boss is fixedly connected to the fabric layer. Figure 5 As shown.

[0075] When this type of strapping device is installed on a wearable item, the end of the fixing base 120 with the upper flange 122 is inserted through the mounting through hole 301 from bottom to top, or the end with the mounting flange 125 is squeezed into the mounting through hole 301 from top to bottom. The upper flange 122 is exposed outside the fabric layer 300. Then, the mounting flange is fixedly connected to the fabric layer 300 through the fixing area. The edge of the mounting through hole 301 is accommodated in the receiving groove 123, thereby achieving the concealment of the edge of the mounting through hole 301.

[0076] Compared with traditional solutions, when this strapping device is installed on a wearable item, the edge of the mounting through hole 301 is accommodated in the receiving groove 123, thereby concealing the edge of the mounting through hole 301. The shape of the mounting through hole 301 does not need to strictly match the shape of the fixing seat, and any irregular parts or burrs on the edge of the mounting through hole 301 are hidden in the receiving groove 123, thus avoiding the irregular parts or burrs from being exposed and affecting the aesthetics.

[0077] In addition, the edge of the mounting through hole 301 is accommodated in the receiving groove 123, which also has a positioning function for the fabric layer 300. The edge of the mounting through hole 301 is limited in the receiving groove 123, so that it will not move arbitrarily axially, nor will it be in close contact with the mounting flange 125. Thus, space can be reserved between the fabric layer 300 and the mounting flange 125 to facilitate the smooth routing of the straps of wearable items.

[0078] Combination Figure 4 Preferably, in this embodiment, the mounting flange 125 includes a fixed area 1252 and a dynamic area 1254. The fixed area 1252 is fixedly connected to the fabric layer 300 in the area near the mounting through hole 301. Preferably, refer to Figure 5 Within the fixed area 1252, the fabric layer and mounting flange can be sewn and fixed along the sewing thread 302. The dynamic area 1254 corresponds to the thread hole 127, and a stitching area (not shown in the figure) is formed between the dynamic area 1254 and the fabric layer 300 for the tie to pass through. The stitching area, thread hole 127, and inner cavity 126 are sequentially connected. Specifically, referring to the accompanying drawings, in this embodiment, the included angle between the two thread holes 127 is 180°, the fixed areas 1252 are two spaced apart from each other, and the two fixed areas 1252 are separated by two dynamic areas 1254 (the dotted line is the boundary line between the fixed area and the dynamic area). The two fixed areas 1252 and the two dynamic areas 1254 form a complete ring. In other preferred embodiments, the mounting flange may not be a complete ring, and there may be a partial gap. The included angle between the two thread holes 127 can be any angle between 30° and 180°.

[0079] Preferably, in this embodiment, the mounting through hole 301 is circular, and the outer diameter of the upper flange 122 is larger than the diameter of the mounting through hole 301. The shape of the mounting through hole 301 can be regular or irregular. When the shape of the mounting through hole 301 is irregular, the outer diameter of the upper flange is preferably approximately the diameter of its circumcircle. This design allows the edge of the mounting through hole 301 to be covered and hidden by the upper flange.

[0080] Preferably, in this embodiment, the lacing device 100 further includes a housing 140 disposed within the inner cavity 126, a spool 160 disposed within the housing 140 for winding the lacing, a cap 190 rotatably disposed on the housing, and a backstop assembly. The lacing device 100 includes a winding lacing mode and a loosening lacing mode. The backstop assembly prevents the cap and the spool from rotating in the loosening direction during the winding lacing mode. In this embodiment, the backstop assembly includes a toothed groove (first backstop member, not shown in the figure), an offset member 180 (second backstop member), and a stop block 143. The toothed groove is disposed on the cap, and the offset member 180 and the stop block 143 are disposed on the housing. The anti-rotation principle of this backstop assembly can be found in patent CN202410035435.3.

[0081] The housing 140 is provided with a tie hole 142 that communicates with the threading hole 127, and the spool 160 communicates with the threading hole 127 through the tie hole 142. At this time, after the tie passes through the threading hole 127 to the inner cavity 126 of the fixing base 120, it can continue to pass through the tie hole 142 and connect with the spool 160.

[0082] Preferably, in this embodiment, the cavity wall of the inner cavity 126 is provided with a snap-fit ​​portion 128, and the outer side of the housing 140 is provided with a snap-fit ​​mating portion 144 that snaps into the snap-fit ​​portion 128. This structural arrangement allows for a detachable connection between the housing 140 and the fixing seat 120, facilitating the repair and replacement of the strapping device after damage. Specifically, referring to the accompanying drawings, in this embodiment, the snap-fit ​​portion 128 is a slot, and the snap-fit ​​mating portion 144 is a protrusion. When the housing 140 and the fixing seat 120 are assembled, preferably, the strapping hole 142 is aligned with the threading hole 127, so that after the strap extends through the threading hole 127, it passes through the strapping hole 142 and enters the interior of the housing to connect with the winding drum 160.

[0083] Combination Figures 7 to 12 The present invention discloses another embodiment of the lacing device 200, which is used to adjust the lacing on a wearable article. The wearable article has an installation area, which includes a fabric layer 400 and an installation through hole 401.

[0084] The lacing device 200 includes a mounting base 220.

[0085] The fixing base 220 includes a columnar body 221. The outer side of the columnar body 221 is provided with an upper flange 222, a receiving groove 223, a lower boss 224 and a mounting flange 225 from top to bottom. The upper flange 222, the receiving groove 223, the lower boss 224 and the mounting flange 225 are all annular, and the upper flange 222 and the lower boss 224 together form the receiving groove 223.

[0086] The columnar body 221 has an inner cavity 226, and the side wall of the lower boss 224 is provided with a wire hole 227 that communicates with the inner cavity 226.

[0087] The mounting base 220 has an upper flange 222 that extends from bottom to top through the mounting through hole 401, or the mounting flange 225 that is located is squeezed from top to bottom into the mounting through hole 401. The upper flange 222 is exposed outside the fabric layer 400, and the edge of the mounting through hole 401 is accommodated in the receiving groove 223. The mounting flange 225 is located below the fabric layer 400, and the area of ​​the fabric layer 400 near the mounting through hole 401 is fixedly connected to the mounting flange 225. It is preferred to use a sewing machine for fixing.

[0088] The basic structure of the mounting base 220 is largely the same as that of the mounting base 120, the difference being in the combination... Figure 9 and Figure 10 The mounting flange 225 includes a fixed area 2252 and a dynamic area 2254. The fixed area 2252 is fixedly connected to the area of ​​the fabric layer 400 near the mounting through hole 401, or in other words, the mounting flange is fixedly connected to the fabric layer near the area adjacent to the lower boss. Preferably, it is combined with... Figure 11 Within the fixed area 2252, the fabric layer and mounting flange can be sewn together along the corresponding sewing line 402. Specifically, in this embodiment, as follows... Figure 10 As shown, the mounting flange 225 is an annular ring with a notch 2255. The fixed area 2252 is a single unit, while the dynamic area 2254 (the dashed line is the boundary between the fixed area and the dynamic area) can be a single unit, or it can be as follows: Figure 10 As shown, the dynamic area 2254 is divided into two segments by the notch 2255. The dynamic area 2254 corresponds to two threading holes 227, and a threading channel (not shown) is formed between the dynamic area 2254 and the fabric layer 400, allowing the tie to pass through. The threading channel, threading holes 227, and inner cavity 226 are sequentially connected. Of course, the tie can also slide within the space between the notch 2255 and the fabric layer.

[0089] Furthermore, in conjunction with the appendix Figure 10 In this embodiment, there are two threading holes 227, and the included angle α between the two threading holes 227 is 90°. The included angle α is the angle between the central axes L1 and L2 (shown by the dotted line) of the two threading holes 227. More preferably, the central axes L1 and L2 both pass through the center O of the top view of the fixed base column-shaped main body. In other preferred embodiments, the included angle α can be any angle within the range of 30° to 180°.

[0090] Furthermore, in this embodiment, the lower boss 224 has a protruding lug structure on its sidewall, and the thread hole 227 is a channel or hole connecting the lug structure and the sidewall of the lower boss. Unlike the fixing seat 120, the lug structure hinders the sewing operation between the mounting flange and the fabric layer, so as... Figure 10 and Figure 11 As shown, neither the fixing area 2252 of the mounting flange nor the sewing thread 402 area includes the area corresponding to the lug structure. Since the included angle of the two thread holes 227 is relatively small in this embodiment, the area covered by the two thread holes 227 is set as the dynamic area. Even the mounting flange can be provided with a notch here. This will not only not affect the fixing effect between the mounting flange and the fabric layer and save materials, but the setting of the notch also makes it possible to avoid the foot-gripping effect when the fixing seat is installed at the shoe tongue position.

[0091] The lacing device 200 also includes a backstop component. The backstop component in this embodiment has the same structure and principle as the backstop component used in the lacing device 100. The backstop component is designed to prevent the cap and the winding drum from rotating in the unwinding direction during the winding lacing mode, thereby preventing the lacing from accidentally coming loose. It should be noted that the backstop component is not limited to... Figure 1 and Figure 7 The toothed groove-offset component-stop assembly shown can be any other mechanical structure that can prevent reversal, such as the common ratchet-pawl assembly.

[0092] The aforementioned strap devices 100 and 200 can be applied to various devices that use straps for tension adjustment, such as backpacks and cases with straps. The following description uses the application of strap devices 100 and 200 to wearable items as an example.

[0093] This utility model also discloses a wearable article according to one embodiment, including a tie and the above-described tie device, wherein the tie is hidden below the fabric layer.
