Description

[Technical field]

[0001] The present invention relates to a connecting structure, a method for attaching the connecting structure, and a mounting tool for the connecting structure. More particularly, the present invention relates to a string connecting structure, a method for attaching the string connecting structure, and a mounting tool for the string connecting structure for wrapping a string around or passing the string. [Background technology]

[0002] Generally, wearable articles such as shoes include laces and holes, and the laces can be threaded through the holes and tied to secure the wearable article to the article being worn. However, conventional tying laces are prone to loosening, making it inconvenient to put on and take off the wearable article.

[0003] As a result, some skilled in the art have developed string connection structures, such as reel devices and string guides, that can be disposed on a wearable article such that the string passes through the string guide and is coupled to the reel device, and the reel device can be operated to loosen or tighten the string, making it suitable for donning and doffing the wearable article.

[0004] However, since the conventional string connection structure is attached to the wearable article by sewing, the manufacturing time is long and the seams may affect the appearance. Therefore, some people in the art have developed welding methods to connect the string connection structure to the wearable article. However, when the string is tightened, the string may pull the string connection structure, and if the bond strength between the wearable article and the string connection structure is not sufficient, the wearable article may be damaged or the string connection structure may be separated. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above, a goal that has been pursued by those skilled in the art is how to improve the structural configuration of the cord connector and increase the bonding strength between the wearing article and the cord connector. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a strap connection structure adapted for attachment to an article. The strap connection structure includes a mounting bracket. The mounting bracket includes a body and a support. The support extends integrally outwardly from an outer circumferential surface of the body. The support and the body are made of a first thermoplastic material. The support is covered by the article.

[0007] According to another aspect of the present invention, there is provided a strap connection structure adapted for attachment to an article. The strap connection structure includes a mounting bracket. The mounting bracket includes a body, a support, and a mounting flange. The support extends integrally outward from an outer periphery of the body. The support and the body are made of a first thermoplastic material.

The second thermoplastic material has a melting point lower than the melting point of the first thermoplastic material, and the mounting flange is configured to be welded to the article.

[0008] According to yet another aspect of the present invention, a method for attaching a strap connection structure includes a mounting bracket arrangement step and a mounting bracket welding step, in which an article includes an upper layer and a lower layer, and at least one strap connection structure mounting bracket is arranged on the article, and the at least one strap connection structure mounting bracket includes a body and a support portion, the body and the support portion being made of a first thermoplastic material, and the at least one strap connection structure support portion is arranged between the upper layer and the lower layer, and in the mounting bracket welding step, thermal energy is supplied to weld the upper layer and the lower layer to couple the at least one strap connection structure mounting bracket to the article.

[0009] According to yet another aspect of the present invention, a mounting tool for a cord connection structure, which is applied to mount the mounting bracket of the cord connection structure described above to an article, includes a first mold and a second mold. The first mold includes a first pressing seat, and the first pressing seat is for placing the mounting bracket thereon. The second mold corresponds to the first mold and includes a second pressing seat. The article includes an upper layer and a lower layer. When the mounting bracket is placed between the first pressing seat and the second pressing seat, the upper layer is located between the support part and the first pressing seat, and the lower layer is located between the second pressing seat and the support part, and the first pressing seat and the second pressing seat generate thermal energy to weld the upper layer, the lower layer, and the support part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. In the following, in order to clearly explain the contents, many actual details are mentioned together with the description. However, the reader will understand that the actual details do not limit the present invention. In other words, in some embodiments of the present invention, the actual details are not necessary. Furthermore, in order to simplify the drawings, some conventional structures and elements are shown in the drawings in a simplified manner, and the repeated elements may be given the same or similar reference numerals.

[0013] Furthermore, although terms such as first, second, third, etc. are used herein to describe various elements or components, these elements or components should not be limited by these terms. As a result, a first element or component described below can be referred to as a second element or component. Furthermore, the combination of elements, components, mechanisms, and modules is not a well-known, usual, or conventional combination, and whether the combination could be readily completed by one of ordinary skill in the art cannot be determined based on whether the elements, components, mechanisms, or modules themselves are well-known, usual, or conventional.

[0014] FIG. 1 is a three-dimensional schematic diagram of a cord connection structure 1000 according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view showing the cord connection structure 1000 of the first embodiment of FIG. 1 attached to an article A1. The cord connection structure 1000 is applied to be attached to the article A1. The cord connection structure 1000 includes a mounting bracket 1100. The mounting bracket 1100 includes a main body 1120 and a support part 1110. The support part 1110 extends outward from an outer circumferential surface 1121 of the main body 1120. The support part 1110 and the main body 1120 are made of a first thermoplastic material. The support part 1110 is covered by the article A1.

[0015] Therefore, the strength of the connection between the mounting bracket 1100 and the article A1 is improved by the structure of the support portion 1110. The string connecting structure 1000 will be described in detail below.

[0016] The first embodiment of the string connection structure 1000 can be used as a string guide member. The main body 1120 may be substantially semi-elliptical in shape and includes a curved outer circumferential surface 1121. The support portion 1110 extends integrally outward from the outer circumferential surface 1121, and the length of the support portion 1110 along the X-axis is longer than the length of the main body 1120 along the X-axis.

[0017] The string connection structure 1000 may further include a passage 1200 disposed in the mounting bracket 1100 for the string to pass therethrough, the passage 1200 being particularly disposed in the body 1120. As shown in Figures 1 and 2, the body 1120 may further include a protrusion portion proximate the support portion 1110 and a base portion remote from the support portion 1110. The protrusion portion is higher than the base portion, the outer peripheral surface 1121 is an outer side surface of the protrusion portion, and the passage 1200 is disposed inside the protrusion portion.

[0018] The article A1 may include an upper layer A11 and a lower layer A12. The upper layer A11 includes a hole for the main body 1120 to be exposed therethrough. The support 1110 is between the upper layer A11 and the lower layer A12, and the upper layer A11 and the lower layer A12 are welded to connect the mounting bracket 1100 and the article A1. To be precise, the upper layer A11 and the lower layer A12 may be cloth or nylon. The size and shape of the hole in the upper layer A11 correspond to the size and shape of the main body 1120, respectively. Therefore, when the mounting bracket 1100 is placed between the upper layer A11 and the lower layer A12, the main body 1120 can be exposed therethrough. In other embodiments, the upper layer may include two passage openings corresponding to the two passage entrances of the passage, respectively, and the upper layer covers the entire main body and the support. The string can enter the passage through the passage entrance and the passage opening, and the main body is not limited to being completely exposed from the upper layer. The mounting bracket is welded to one of the upper and lower layers and the other of the upper and lower layers is attached thereto, such that the article covers the support.

[0019] The melting point of the first thermoplastic material may be 60°C or more and 250°C or less. Thus, a method such as thermocompression, ultrasonic welding, high frequency welding, etc. is used to supply heat energy to at least partially weld and bond the upper layer A11, the lower layer A12, and the support 1110 to each other. Thus, the mounting bracket 1100 can be attached to the article A1. It should be noted that the mounting bracket 1100 in FIG. 2 aligns the side edges of the article A1, but in other embodiments, the article may surround the body when the support surrounds the body. Furthermore, the distance between the support 1110 and the outer peripheral surface 1121 is 2 mm or more, and this distance indicates the distance between the farthest point of the contour of the outer peripheral surface 1121 and the closest point of the contour of the support 1110.

[0020] As shown in FIG. 2, the article A1 may further include at least one central layer A13, which is located between the upper layer A11 and the lower layer A12. To be precise, the central layer A13 can be located on the lower layer A12, on which the mounting bracket 1100 and the upper layer A11 are located. As a result, when heat energy is supplied to bond the upper layer A11, the lower layer A12 and the support 1110, the central layer A13 can be located between the lower layer A12 and the mounting bracket 1100 to enhance the bonding strength. The central layer A13 may be an adhesive or a meltable plastic, but the present invention is not limited thereto. In another embodiment, the size of the central layer is the same as the size of the support, but it should be noted that the present invention is not limited thereto.

[0021] FIG. 3 is a three-dimensional schematic diagram of a string connection structure 2000 according to a second embodiment of the present invention. FIG. 4 is a cross-sectional view showing the state in which the string connection structure 2000 of the second embodiment of FIG. 3 is attached to an article A1. The string connection structure 2000 of the second embodiment is similar to the string connection structure 1000 of the first embodiment, except that the support portion 2110 includes a plurality of spaced apart through holes 2111. In other words, the support portion 2110 can include a support sheet 2112, and the through holes 2111 pass through the support sheet 2112. Therefore, after the upper layer A11, the lower layer A12 and the support portion 2110 are welded, the upper layer A11 and the lower layer A12 located at the through hole 2111 are also welded, and the bonding strength between the article A1 and the string connection structure 2000 is improved, which is advantageous in avoiding the string connection structure 2000 from being separated from the article A1 when the article A1 and the string connection structure 2000 are pulled by an external force.

[0022] Furthermore, the central layer A13 may be disposed below the upper layer A11, and when heat energy is provided to bond the upper layer A11, the lower layer A12, and the support 2110, the central layer A13 may be located between the upper layer A11 and the support 2110. In other embodiments, the number of central layers may be two, and the two central layers may be disposed below the upper layer and above the lower layer, respectively, but the present invention is not limited thereto. It should be noted that although the structures of the upper layer A11, the central layer A13, the support 2110, and the lower layer A12 are illustrated separately in FIG. 4, these structures may be fused together, and are not limited by the drawings.

[0023] Fig. 5 is a three-dimensional schematic diagram of a string connection structure 3000 according to a third embodiment of the present invention. Fig. 6 is an exploded view of the string connection structure 3000 of the third embodiment of Fig. 5. The string connection structure 3000 is a reel device, and therefore the string connection structure 3000 may further include a reel assembly 3300. The reel assembly 3300 includes a housing 3310 disposed on the mounting bracket 3100 and removably coupled to the mounting bracket 3100 to form an interior space together with the mounting bracket 3100, and a spool 3320 located within the interior space and configured to have a string wound around it.

[0024] More specifically, the reel assembly 3300 may further include an engagement unit 3330, a knob 3340, and a coupling unit 3350. The engagement unit 3330 is disposed above the spool 3320, the knob 3340 covers the housing 3310, and the coupling unit 3350 couples the spool 3320 and the knob 3340. By operating the knob 3340, the string is wound on the spool 3320 or loosened from the spool 3320. In the present invention, the reel assembly 3300 is not an improvement, so details thereof will not be described. Furthermore, the components of the reel assembly 3300 can be replaced with other components having the same functions, and the present invention is not limited thereto.

[0025] The main body 3120 and the support portion 3110 may be disk-shaped, and the main body 3120 may further include engagement holes corresponding to tabs of the housing 3310 so as to be attached to the housing 3310. Thus, when the mounting bracket 3100 is attached to an article using a method similar to that of the first embodiment, the main body 3120 can be exposed for coupling to the housing 3310. Other details similar to those of the first embodiment will not be repeated.

[0026] 7 is a three-dimensional schematic diagram of a strap-connected mounting bracket 4100 according to a fourth embodiment of the present invention. The mounting bracket 4100 is similar to the mounting bracket 3100 of the third embodiment and includes a main body 4120 and a support portion 4110, but the support portion 4110 may include a support sheet 4112 and a plurality of through holes 4111 passing through the support sheet 4112.

[0027] 8 is a three-dimensional schematic diagram of a mounting bracket 5100 of a strap connection structure according to a fifth embodiment of the present invention. The mounting bracket 5100 is similar to the mounting bracket 3100 of the third embodiment, but the shape of the support portion 5110 is different.

[0028] 9 is a three-dimensional schematic diagram of a mounting bracket 6100 of a strap connection structure according to a sixth embodiment of the present invention. The mounting bracket 6100 is similar to the mounting bracket 4100 of the fourth embodiment, but the shape of the support portion 6110 is different.

[0029] FIG. 10 is a three-dimensional schematic diagram of one of the mounting brackets 7100 of the strap connection structure according to the seventh embodiment of the present invention. FIG. 11 is another three-dimensional schematic diagram of the mounting bracket 7100 of the seventh embodiment of FIG. 10. The mounting bracket 7100 includes a body 7120, a support portion 7110, and a mounting flange 7130. The support portion 7110 extends outward from the outer periphery of the body 7120. The support portion 7110 and the body 7120 are made of a first thermoplastic material. The mounting flange 7130 extends outward from the body 7120 and is connected to the support portion 7110. The mounting flange 7130 is made of a second thermoplastic material. The melting point of the second thermoplastic material is less than the melting point of the first thermoplastic material, and the mounting flange 7130 is configured to be welded to be coupled to the article A1 (shown in FIG. 12). The melting point of the first thermoplastic material and the melting point of the second thermoplastic material may be 60°C or more and 250°C or less.

[0030] FIG. 12 is a partial cross-sectional view taken along line 12-12 of the mounting bracket 7100 of the seventh embodiment of FIG. 10 in a state where the mounting bracket 7100 is attached to the article A1. FIG. 13 is a partial cross-sectional view taken along line 13-13 of the mounting bracket 7100 of the seventh embodiment of FIG. 10 in a state where the mounting bracket 7100 is attached to the article A1. Referring to FIGS. 10-11 and to FIGS. 12-13, the support portion 7110 of the mounting bracket 7100 includes four support frames 7113, four ribs 7114 and four through holes 7111. Two of the support frames 7113 are located on one side of the main body 7120 with respect to the Y axis and are spaced apart from each other along the axis of the main body 7120. The other two of the support frames 7113 are located on the other side of the main body 7120 with respect to the Y axis and are spaced apart from each other along the axis of the main body 7120. Similarly, two of the ribs 7114 are located on one side of the body 7120 with respect to the X-axis and are spaced apart from each other along the axis of the body 7120. The other two of the ribs 7114 are located on the other side of the body 7120 with respect to the X-axis and are spaced apart from each other along the axis of the body 7120. The four through holes 7111 are located in the four support frames 7113, respectively.

[0031] In the seventh embodiment, the support frame 7113 and the rib 7114 located on the upper side can be regarded as the upper part of the support part 7110, and the support frame 7113 and the rib 7114 located on the lower side can be regarded as the lower part of the support part 7110. The upper part may protrude from the upper surface of the mounting flange 7130, and the lower part may protrude from the lower surface of the mounting flange 7130. The main body 7120 may include a ring groove extending inward from its outer circumferential surface to correspond to the gap between the upper part and the lower part, and the ring groove is configured to connect the mounting flange 7130, thereby increasing the bonding strength between the main body 7120 and the mounting flange 7130. In one embodiment, the mounting flange made of the second thermoplastic material is formed first, and then the main body and the support part made of the first thermoplastic material are formed by insert molding, but the present invention is not limited thereto.

[0032] As shown in Fig. 12, when connecting to the article A1, the upper layer A11 and the lower layer A12 clamp the rib 7114 and the mounting flange 7130, and as shown in Fig. 13, the upper layer A11 and the lower layer A12 clamp the support frame 7113 and the mounting flange 7130. Therefore, when performing thermocompression bonding or ultrasonic welding, the temperature can be controlled to melt only the second thermoplastic material with a low melting point, thereby welding the upper layer A11 and the lower layer A12. Such a structure of the support part 7110 can increase the connection strength between the mounting bracket 7100 and the article A1.

[0033] Furthermore, the distance between the outer edge of the mounting flange 7130 along the X-axis and the outer circumferential surface of the body 7120, i.e., the first distance, is greater than 2 mm, e.g., 5 mm. The distance between the furthest point of the support frame 7113 and the outer circumferential surface of the body 7120, i.e., the second distance, and the distance between the furthest point of the rib 7114 and the outer circumferential surface of the body 7120, i.e., the third distance, are smaller than the first distance.

[0034] FIG. 14 is a three-dimensional schematic diagram of a mounting bracket 8100 of a string connection structure according to an eighth embodiment of the present invention. FIG. 15 is a cross-sectional view of the mounting bracket 8100 of the eighth embodiment taken along line 15-15 of FIG. 14. The mounting bracket 8100 is similar to the mounting bracket 7100 of the seventh embodiment, but the support portion 8110 of the mounting bracket 8100 does not include the support frame 7113 and the through hole 7111 as shown in FIG. 10, but includes a plurality of ribs 8114 arranged at intervals. Similarly, two of the ribs 8114 are arranged at the same position near the body 8120 of the mounting bracket 8100 along the axis of the body 8120, but the support portion 8110 further includes a plurality of connecting portions 8115 respectively connected between two of the ribs 8114 arranged at intervals along the axis. Thus, the bonding strength between the mounting flange 8130 and the body 8120 is improved. Other embodiments do not include a connecting portion between the two ribs.

[0035] 16 is a three-dimensional schematic diagram of a strap-connected mounting bracket 9100 according to a ninth embodiment of the present invention. The support portion 9110 of the mounting bracket 9100 may include a support sheet 9112 and a number of through holes 9111 that pass through the support sheet 9112. The through holes 9111 may pass through the support sheet 9112 along the outer circumferential surface of the body 9120, thereby dividing the support sheet 9112 into a number of ribs and annular rings.

[0036] Figure 17 is a three-dimensional schematic view of one of the mounting brackets 10100 of the strap connection structure according to the tenth embodiment of the present invention. Figure 18 is another three-dimensional schematic view of the tenth embodiment mounting bracket 10100 of Figure 17. The mounting bracket 10100 is similar to the mounting bracket 8100 of the eighth embodiment, except that only one rib 10114 is disposed in the same location near the body 10120 of the mounting bracket 10100, the link portion 8115 of the eighth embodiment is not included, and the mounting flange 10130 is disposed above the rib 10114.

[0037] 19 is a block flow chart of a method S1000 for attaching a cord connection structure according to the eleventh embodiment of the present invention. The method S1000 for attaching a cord connection structure includes a step S1100 of arranging a mounting bracket and a step S1200 of welding the mounting bracket.

[0038] 1 and 2, in a mounting bracket placement step S1100, an article A1 includes an upper layer A11 and a lower layer A12. A mounting bracket 1100 of at least one strap connection structure 1000 is placed on the article A1. The mounting bracket 1100 of at least one strap connection structure 1000 includes a body 1120 and a support portion 1110, the body 1120 and the support portion 1110 being made of a first thermoplastic material, and the support portion 1110 of the at least one strap connection structure 1000 is placed between the upper layer A11 and the lower layer A12.

[0039] In the mounting bracket welding step S1200, thermal energy is supplied to weld the upper layer A11 and the lower layer A12 together, thereby joining the mounting bracket 1100 and the article A1.

[0040] The method S1000 for attaching a string connection structure may further include a string connection step S1300. The number of the at least one string connection structure 1000 is two or more. The string connection structures 1000 are arranged on the article A1 at intervals. Each string connection structure 1000 includes a passage 1200 on the mounting bracket 1100. A string is threaded through the passage 1200 in a first one of the string connection structures 1000 (first string connection structure), and then the string is threaded through the passage 1200 in a second one of the string connection structures 1000 (second string connection structure).

[0041] 5 and 6, in another embodiment, in the string connecting step, the number of the at least one string connecting structure 3000 is 1. The string connecting structure 3000 may further include a reel assembly 3300 including a spool 3320, which is connected to the mounting bracket 3100 after the string is wound on the spool 3320.
