Description

tethering guide Technical Field

[0001] This application relates to clothing accessories, and more specifically, to lacing guides attached to shoes, garments, bags, and hats. Background Technology

[0002] In fastening systems consisting of fastening buttons and ties, most currently used tie guides attached to shoes, clothing, and hats are made of plastic buckles or webbing. These guides have straight channels, which are prone to deformation during the thread winding and unwinding process. Furthermore, the high frictional resistance of the channel material increases the frictional resistance of the thread at these points, making it difficult for the thread to pass through and prone to jamming. This results in the user struggling to tighten the ties despite effort. This defect is particularly pronounced when multiple such guides are used in combination, such as in series, making thread winding and unwinding even more difficult and tightening even more challenging.

[0024] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] Therefore, as shown in Figures 1, 2, 3, and 4, some embodiments of this application propose a lacing guide 100 for guiding the lacing thread 200. The guide 100 includes a base 10 for fixing to shoes, clothing, and hats, and a guide structure 20 coupled vertically to the base 10. The guide structure 20 includes a pin portion 21 fixed to the base and an upper shell portion 22 extending radially from one end of the pin portion 21. The guide structure 20 also includes a bearing 30, which can be a sliding bearing or a rolling bearing. Taking the rolling bearing shown in Figures 5 and 6 as an example, the inner ring 31 of the bearing 30 is fitted and fixed to the outer periphery of the pin portion. The outer ring 32 engages the inner ring 31 via balls 33. The outer ring 32 may include circumferential grooves 323 for positioning the lacing thread 200.

[0026] It should be understood that the base 10 and the guide structure 20 define an annular guide space, and the bearing 30 can be configured to be located within the guide space. As a supplement and replacement to the wire groove 323, the positioning of the guide wire can be achieved through the structure of the base 10 and the guide structure 20.

[0027] As shown in Figures 6 and 7, the base 10 includes a lower shell portion 11 for forming the guide space, and a base fixing portion 12 radially outwardly disposed from a first portion on the circumferential edge of the lower shell portion. The lower shell portion 11 includes a base support 111 and a lower sidewall 112 extending upward from the base support. The upper shell portion 22 includes a cover-like portion 221 and an upper sidewall 222 extending axially downward from a second portion on the circumferential edge of the cover-like portion 221. The upper sidewall 222 and the lower sidewall 112 can define the radial boundary of the guide space. The upper sidewall and the lower sidewall form a constraint on the tie wire, while in the locations where the upper shell portion and the lower shell portion do not have the upper sidewall and the lower sidewall, an open opening is formed for the tie wire to enter and exit the guide space, as shown in Figure 9.

[0028] The first arc length of the circumferential edge of the first part covering the base fixing part 12 and the second arc length of the second circumferential edge of the second part covering the cover-like part 222 can be equal, thereby forming an edge structure with completely corresponding upper and lower structures. It should be understood that the first arc length and the second arc length can be unequal, for example, the second arc length can be greater than the first arc length, and vice versa.

[0029] The dimensions of the first arc length and the second arc length determine the size of the opening for the tether guide to extend the tether. For example, in certain requirements, the first arc length may be less than or equal to 50% of the perimeter of the first edge; and the second arc length may be less than or equal to 50% of the perimeter of the second edge.

[0030] Although relative rotation between the base 10 and the guide structure 20 is unlikely to occur, in order to avoid possible rotation, as shown in FIG8, a notch 1121 formed downward from the upper edge of the lower sidewall 112 can be provided, and the corresponding upper sidewall 222 includes a protrusion 2221 formed downward from the lower edge of the upper sidewall 222. The protrusion 2221 and the notch 1121 are configured to engage tightly to limit relative rotation between the two.

[0031] It should be understood that, as an alternative structure, the upper sidewall 222 includes a notch formed upward from the lower edge of the upper sidewall, and the lower sidewall portion includes a protrusion formed upward from the upper edge of the lower sidewall portion, the notch engaging with the protrusion.

[0032] It should be understood that other structures can also be used to limit the relative rotation of the base 10 and the guide structure 20. For example, an axially arranged key can be provided in the pin portion 21, and a keyway that engages with the key can be provided in the intermediate hole 1112 of the base 111; conversely, an axially arranged keyway can also be provided in the pin portion 21, and a key that engages with the keyway can be provided in the intermediate hole 1112 of the base 111.

[0033] As described above, the base support 111 of the base fixing part may include a central hole 1112 as a joining structure with the pin portion 21. It should be understood that the central hole 1112 may be a through hole or a blind hole. The free end 211 of the pin portion 21 may be fixed to the central hole by welding or by a snap-fit ​​structure.

[0034] A first boss 1113 is formed around the periphery of the intermediate hole 1112, and the first boss 1113 is tightly engaged with the first surface 311 of the inner ring 31 of the bearing 30; a second boss 23 is formed between the pin portion 21 and the cover portion 22 of the guide member 20, and the second boss 23 is tightly engaged with the second surface 312 of the inner ring 31 of the bearing 30.

[0035] In some embodiments, the lower housing 11 includes a first annular groove 1114 located radially outside the outer periphery of the first boss 1113, corresponding to the outer ring 32 of the bearing 30; and the cover portion 221 includes a second annular groove 2212 located radially outside the outer periphery of the second boss 2211, corresponding to the outer ring of the bearing.

[0036] To prevent the tie wire from detaching from the wire groove, the distance between the first annular groove 1114 and the first surface 321 of the outer ring 32 is smaller than the diameter of the tie wire 200, and the distance between the second annular groove 2212 and the second surface 322 of the outer ring 32 is smaller than the diameter of the tie wire 200.

[0037] In some embodiments, the distance between the first maximum diameter position of the first surface 321 of the outer ring 32 adjacent to the outer ring and the first annular groove 1114 is greater than the diameter of the tie wire 200, and the distance between the second maximum diameter position of the second surface 322 of the outer ring 32 adjacent to the outer ring 32 and the second annular groove 2212 is greater than the diameter of the tie wire 200.

[0038] The outer edge of the lower housing 11 is rounded, and / or the outer edge of the cover portion 221 is rounded.

[0039] The base fixing part 12 is an inverted disc shape. The base fixing part 12 can be fixed to shoes, clothing and hats by means of sewing or seamless hot melt welding.

[0040] The base 10 and the guide structure 20 can be made of any formable material, such as metal, for example stainless steel or aluminum alloy; or non-metallic composite materials, such as polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane (TPU), polyamide (PA) or copolyester (PETG, PCTG, etc.) formed by an integral molding process.

[0041] The coefficient of friction between the groove 323 of the outer ring of the bearing 30 and the guide wire is not subject to excessive requirements, as the provided bearing is sufficient to guarantee this. However, if the coefficient of friction between the groove 323 of the outer ring and the guide wire is determined to ensure that the frictional force between the guide wire and the groove 323 is greater than the resistance of rolling friction between the inner and outer rings of the bearing, this can prevent the guide wire from moving on the outer ring of the bearing and causing slippage, thereby increasing the guiding accuracy.

[0042] It should be understood that the material of the tie 200 here is not limited and can be natural fiber thread such as cotton, silk, or leather, or synthetic fiber thread.

[0043] This application provides a thread guide including a bearing. Using the bearing as the core guiding component, it makes the movement of the thread smoother, allowing the thread to roll within the track without sliding friction. This solves all the aforementioned problems, making it convenient, labor-saving, and reducing wear while increasing service life. The thread guide can be used to guide threads in shoes, clothing, bags, and hats.

Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
