[0028] It should be understood that while terms such as “first,” “second,” and “third” may be used in this document to describe various elements or features, these elements or features should not be limited by these terms. These terms are primarily used to distinguish one element from another, or one feature from another. Furthermore, the term “or” as used herein may, depending on the context, include any combination of one or more of the related listed items.

[0029] Please see Figures 1 to 10 As shown, this is one embodiment of the present invention. Figure 1 and Figure 2As shown, this embodiment discloses a cord adjustment module 100, which includes a cord buckle mechanism 1 and a cord 2 installed on the cord buckle mechanism 1. The cord adjustment module 100 can be applied to an object, and in this embodiment, the object is described as a shoe body 200, which includes a sole 201 and a vamp 202 connected to the sole 201. However, this invention is not limited to this. For example, in other embodiments not shown in this invention, the object may also be of other types (such as clothing, trousers, or various bags) depending on actual needs.

[0030] It should be noted that although the rope buckle mechanism 1 is described in this embodiment in conjunction with the rope 2, this utility model is not limited thereto. For example, in other embodiments not shown in this utility model, the rope buckle mechanism 1 may also be used alone (e.g., for sale) or in conjunction with other components, depending on actual needs.

[0031] In this embodiment, the cord buckle mechanism 1 is defined as not containing any elastic member; that is, any buckle configured with an elastic member (such as a spring) is different from the cord buckle mechanism 1 referred to in this embodiment. The cord buckle mechanism 1 includes a female buckle 11 installed on the shoe upper 202 and a male buckle 12 movably inserted through the female buckle 11.

[0032] More specifically, such as Figures 3 to 5 As shown, the female buckle 11 includes a main body 111 and a fixing part 112 connected to one end of the main body 111. The fixing part 112 is fixed to the upper part 202 and allows the main body 111 to rotate relative to the upper part 202 under force. In this embodiment, the fixing part 112 is described as a webbing wrapped around the main body 111, and the webbing is sewn to the upper part 202, but this invention is not limited to this. For example, in other embodiments not shown in this invention, the fixing part 112 may be a sewn piece integrally extended from the main body 111, which is sewn to the upper part 202.

[0033] Furthermore, the female buckle 11 (e.g., the main body 111) forms an accommodating space 113, and the female buckle 11 (e.g., the main body 111) forms a first opening 114 and a second opening 115 respectively connected to both ends of the accommodating space 113, and the female buckle 11 forms a positioning groove 1112a connected to the accommodating space 113 and the second opening 115.

[0034] In this embodiment, the positioning groove 1112a has two protrusions 1112b at its opening; wherein the groove wall of the positioning groove 1112a is generally U-shaped, and the two protrusions 1112b are respectively located at the two ends of the groove wall to narrow the opening of the positioning groove 1112a. However, the number of protrusions 1112b can also be adjusted according to actual needs; for example, the positioning groove 1112a may also have at least one protrusion 1112b at its opening.

[0035] It should be noted that, in order to facilitate a clearer understanding of the female buckle 11 in this embodiment, the following content will describe its structure using one of the feasible forms of the female buckle 11, but this utility model is not limited thereto.

[0036] Furthermore, in this embodiment, the main body 111 is a single-piece structure integrally formed, comprising a bottom wall 1111, a top wall 1112, two side walls 1113 connecting the bottom wall 1111 and the top wall 1112, and a fastener 1114 connected to the bottom wall 1111. The bottom wall 1111, the top wall 1112, and the two side walls 1113 are identical and together form a generally annular structure, with the first opening 114 and the second opening 115 formed at their respective ends.

[0037] The bottom wall 1111 has a guide groove 1111a recessed at the center corresponding to the second opening 115. A limiting post 1111b is formed on the bottom wall 1111 adjacent to the first opening 114. Furthermore, a through-type track groove 1111c is formed between the guide groove 1111a and the limiting post 1111b on the bottom wall 1111. In other words, the guide groove 1111a, the track groove 1111c, and the limiting post 1111b are arranged generally in a straight line.

[0038] Furthermore, the top wall 1112 has a recessed positioning groove 1112a at the portion corresponding to the first opening 114, and the positioning groove 1112a is generally located above one end of the guide groove 1111a and the track groove 1111c. That is, the projection area formed by the positioning groove 1112a of the top wall 1112 projected onto the bottom wall 1111 surrounds one end of the guide groove 1111a and the track groove 1111c.

[0039] Furthermore, the fixing part 112 is mounted on the buckle 1114, and the buckle 1114 and the fixing part 112 are adjacent to the second opening 115. That is, the female buckle 11 is adjacent to the upper part 202 with the bottom wall 1111.

[0040] The male buckle 12 passes through the receiving space 113 of the female buckle 11 and can be unlocked along the female buckle 11 at a position away from the second opening 115 (e.g.: Figure 2 and Figure 10 ) and a locking position adjacent to the second opening 115 (e.g.: Figure 1 and Figure 5 It should be emphasized that there is no elastic member between the male buckle 12 and the female buckle 11 to drive their relative movement.

[0041] It should be noted that the male buckle 12 in this embodiment is a single-piece structure integrally formed, and in order to facilitate a clearer understanding of the male buckle 12, the following content will describe its structure using one of the feasible forms of the male buckle 12, but this utility model is not limited thereto.

[0042] like Figures 3 to 5 As shown, the male buckle 12 includes a body portion 121, a locking portion 122 connected to one end of the body portion 121, and an unlocking portion 123 adjacent to the other end of the body portion 121. The body portion 121 has a cord-receiving space 1211 formed within it, and the body portion 121 has at least one front opening 1212 communicating with one end of the cord-receiving space 1211, and two rear openings 1213 communicating with the other end of the cord-receiving space 1211.

[0043] Furthermore, at least one of the front openings 1212 is adjacent to the unlocking part 123, and in this embodiment, the number of such openings is described as two. The body part 121 also forms a limiting groove 1214 that divides the rope-containing space 1211 into two regions, and the opening of the limiting groove 1214 is generally located between the two front openings 1212, but this invention is not limited thereto. Moreover, the two rear openings 1213 correspond to the two front openings 1212 respectively, and the two rear openings 1213 are separated by the locking part 122.

[0044] The locking part 122 is generally T-shaped and has a dividing section 1221, two clamping sections 1222 connected to one end of the dividing section 1221, and a protrusion 1223 connected to the other end of the dividing section 1221. The dividing section 1221 is plate-shaped and connected to the body part 121, and the dividing section 1221 separates the two rear openings 1213, while the protrusion 1223 is adjacent to the limiting groove 1214. Furthermore, the two clamping sections 1222 are connected to the body part 121 and are located on opposite sides of the dividing section 1221; that is, the two clamping sections 1222 are adjacent to the two rear openings 1213, and the two clamping sections 1222 are located on the same side of the two rear openings 1213 (e.g., ...). Figure 7 (The two rear openings 1213 are located on the upper side).

[0045] The unlocking part 123 is generally annular, and in this embodiment, a strap 13 is additionally attached to the unlocking part 123. The strap 13 is annular and installed on the unlocking part 123; that is, the strap 13 is not fixed to the upper part 202, so that the user can operate the unlocking part 123 by applying force to the strap 13. However, this utility model is not limited to this. For example, in other embodiments of this utility model not shown, one end of the strap 13 is installed on the unlocking part 123, while the other end of the strap 13 is fixed to the upper part 202; or, the strap 13 may be omitted or replaced by other components according to actual needs.

[0046] Furthermore, the male buckle 12 is inserted into the receiving space 113 of the female buckle 11 through the second opening 115 with the unlocking part 123, so that the limiting groove 1214 moves along the limiting post 1111b, and the protrusion 1223 enters the track groove 1111c via the guide groove 1111a, thereby making the position of the locking part 122 correspond to the positioning groove 1112a, and the two clamping sections 1222 of the locking part 122 move away from the fixing part 112.

[0047] Therefore, the mutual limiting engagement of the limiting groove 1214 and the limiting post 1111b prevents the male buckle 12 from disengaging from the female buckle 11 through the first opening 114; and the mutual limiting engagement of the protrusion 1223 and the track groove 1111c prevents the male buckle 12 from disengaging from the female buckle 11 through the second opening 115. However, this invention is not limited to the above. For example, in other embodiments not shown in this invention, the engagement of the limiting groove 1214 and the limiting post 1111b or the engagement of the protrusion 1223 and the track groove 1111c can be replaced by other structures according to actual needs.

[0048] like Figures 5 to 9 As shown, the cord 2 has a restraint portion 21 that passes through the upper part of the shoe 202 and an adjustment portion 22 that extends out of the upper part of the shoe 202, and the adjustment portion 22 is installed on the cord buckle mechanism 1 (e.g., the male buckle 12). The adjustment portion 22 has two built-in sections 221, a control section 222 connected to one end of the two built-in sections 221, and two adjustment sections 223 respectively connected to the other end of the two built-in sections 221.

[0049] More specifically, the two built-in segments 221 are located within the cord-receiving space 1211 of the body portion 121 of the male buckle 12. The control segment 222 is connected to the two built-in segments 221 that respectively extend from the two rear openings 1213, and the control segment 222 is adjacent to the locking portion 122. Furthermore, the two adjustment segments 223 extend from the upper part 202; that is, the two adjustment segments 223 are connected to the restraint portion 21.

[0050] It should be noted that the control segment 222 in this embodiment is described as a continuous section of the rope 2, but in other embodiments not shown in this utility model, the control segment 222 may also be formed by fixing two rope ends together, depending on actual needs.

[0051] The above content is a structural description of the shoe body 200 (or the cord adjustment module 100). The following content will describe the operation of the cord adjustment module 100.

[0052] like Figures 5 to 9 As shown, when the control segment 222 is pulled away from the upper part 202 and positioned within the positioning groove 1112a, causing the male buckle 12 to move relative to the female buckle 11 to the locking position, the two adjustment segments 223 generate tension and press the male buckle 12 towards the second opening 115. The locking part 122 is adjacent to the positioning groove 1112a, and at least one positioning slit S is formed between the locking part 122 and the adjacent groove wall of the positioning groove 1112a. The control segment 222 is fixed within at least one positioning slit S under pressure and deformation.

[0053] Therefore, the rope buckle mechanism 1 can effectively position the rope 2 without using an elastic component, through the structural cooperation of the male buckle 12, the female buckle 11, and the adjustment part 22 (e.g., the pulling of the control section 222 drives the male buckle 12 and the female buckle 11 to move relative to each other to form at least one positioning slit S, thereby positioning the control section 222).

[0054] In addition, such as Figure 10 As shown, when the unlocking part 123 is pulled away from the shoe upper 202, causing the male buckle 12 to move relative to the female buckle 11 to the unlocking position, the adjusting part 22 of the cord 2 has no tension, thus allowing the cord 2 to adjust its tightness according to the user's needs.

[0055] It should be further explained that when the control segment 222 is pulled away from the shoe upper 202 (e.g., the control segment 222 is pulled upward), the cord buckle mechanism 1 is fixed to the shoe upper 202 by the fixing part 112 of the female buckle 11, so that the cord buckle mechanism 1 can rotate relative to the shoe upper 202, so as to facilitate the male buckle 12 to move to the locking position relative to the female buckle 11. However, this utility model is not limited to this.

[0056] Furthermore, the way in which the locking part 122 and the positioning groove 1112a jointly clamp and position the control section 222 can be adjusted and changed according to actual needs. However, for ease of understanding, the following description will use one form of the rope adjustment module 100, but this utility model is not limited thereto.

[0057] like Figures 5 to 9 As shown, when the male buckle 12 is in the locked position, each of the front openings 1212 is exposed outside the first opening 114, so that each of the adjustment sections 223 can press against the hole wall of the corresponding front opening 1212, and each of the clamping sections 1222 and the adjacent groove wall of the positioning groove 1112a jointly clamp the control section 222.

[0058] More specifically, when the male buckle 12 is in the locked position, each of the clamping segments 1222 and the adjacent groove wall of the positioning groove 1112a together form a positioning slit S, and the rope diameter D2 of the rope 2 is greater than the width W of any of the positioning slits S, so that the control segment 222 is fixed within each positioning slit S by compression deformation.

[0059] Furthermore, when the male buckle 12 is in the locked position, the two protrusions 1112b are respectively located at the ends of the two positioning slits S (that is, each positioning slit S and the corresponding protrusion 1112b are adjacent to a rear opening 1213), and the distance L between each protrusion 1112b and the locking part 122 (e.g., the corresponding clamping section 1222) is less than the width W of the corresponding positioning slit S, thereby effectively preventing the control section 222 from falling out of the corresponding positioning slit S through each protrusion 1112b.

[0060] From another perspective, when the male buckle 12 is in the locked position, the width W of each positioning slit S is between 40% and 50% of the diameter D1213 of the corresponding rear opening 1213, and the distance L between each protrusion 1112b and the locking part 122 (e.g., the corresponding clamping section 1222) is between 30% and 40% of the diameter D1213 of the corresponding rear opening 1213.

[0061] Furthermore, each of the protrusions 1112b and the end of the adjacent clamping segment 1222 respectively form two guide ramps G, the distance between which gradually increases in the direction away from the corresponding positioning slit S, so as to facilitate the control segment 222 to enter the corresponding positioning slit S through any two adjacent guide ramps G.

[0062] It should be noted that the rope buckle mechanism 1 in the above description of this embodiment is described with two positioning slits S and their corresponding structures, but the number of positioning slits S can also be adjusted and changed according to actual needs; that is, the rope buckle mechanism 1 can also be formed with at least one positioning slit S.

[0063] [Technical Effects of the Embodiments of this Utility Model]

[0064] In summary, the rope adjustment module and rope buckle mechanism disclosed in this utility model embodiment, through the structural cooperation of the male buckle, the female buckle, and the rope (e.g., the pulling of the control section drives the male buckle and the female buckle to move relative to each other to form at least one positioning slit, thereby positioning the control section), can effectively achieve the positioning of the rope without using an elastic component structure, thereby effectively improving the installation and operation convenience of the rope buckle mechanism and enabling the rope buckle mechanism to position the rope more stably.

[0065] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the patent scope of the present utility model. Therefore, all equivalent technical changes made based on the contents of the present utility model specification and drawings are included in the patent scope of the present utility model.
