[0025] It should be understood that although 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, as appropriate, include any combination of one or more of the related listed items.

[0026] [Example 1]

[0027] Please refer to Figures 1 to 11, which illustrate Embodiment 1 of the present invention. As shown in Figures 1 and 2, this embodiment discloses a wearable product 1000, comprising an object 200, a cord 300 threaded through the object 200, and a buckle assembly 100 disposed on the cord 300. The cord 300 has an adjustment section 300a and two control sections 301 connected to the adjustment section 300a. The adjustment section 300a is disposed on the object 200 (e.g., the adjustment section 300a is disposed around or along a specific path on the object 200), and the two control sections 301 extend beyond the object 200 for adjusting the tightness of the adjustment section 300a. The two control sections 301 are threaded through the buckle assembly 100 and each has a cord end 302 located outside the buckle assembly 100.

[0028] It should be noted that the object 200 in this embodiment is described as a shoe, and the number of the cord 300 is one, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the type of the object 200 can be varied according to actual needs (e.g., backpack, clothes, pants, skirt, or other non-wearable items), and the number and type of the cord 300 can be adjusted accordingly (e.g., the number of the cord 300 can be multiple and one end of it can be fixed to the object 200, and the type of the cord 300 can be an elastic cord or a non-elastic cord); or, the number of the cord 300 is a single cord and it has at least one control segment 301, which has the cord tail end 302, and the cord tail end 302 can be long or looped.

[0029] Furthermore, although the buckle assembly 100 and the cord 300 are described in this embodiment as being paired with the object 200, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the buckle assembly 100 and the cord 300 can be combined and defined as a cord adjustment mechanism, and the cord adjustment mechanism can be used independently (e.g., for sales) or in combination with other components according to actual needs. The structure of the buckle assembly 100 will be described next, followed by the connection relationship between the buckle assembly 100 and other components.

[0030] As shown in Figures 3 to 6, the fastener assembly 100 includes a tubular outer shell 1, a male buckle 2 passing through the outer shell 1, and a female buckle 3 passing through the outer shell 1 and assembled to the male buckle 2. Furthermore, in this embodiment, the fastener assembly 100 can achieve a metal-free design by utilizing the structural cooperation between the outer shell 1, the male buckle 2, and the female buckle 3, thus facilitating recycling operations.

[0031] In this embodiment, the outer shell 1 is a single-piece structure integrally formed, and the outer shell 1 has a first opening 11 and a second opening 12 located at opposite ends. The outer shell 1 also has two recessed grooves 13 formed along a first direction D1 from the first opening 11. The two grooves 13 are located on the inner edge of the outer shell 1 and are arranged facing each other along a thickness direction T perpendicular to the first direction D1. Furthermore, the male buckle 2 passes through the outer shell 1 from the first opening 11 along the first direction D1, while the female buckle 3 passes through the outer shell 1 from the second opening 12 along a second direction D2 opposite to the first direction D1 and is assembled to the male buckle 2. However, the assembly order of the outer shell 1 relative to the male buckle 2 and the female buckle 3 can be adjusted and varied according to actual needs, and is not limited here.

[0032] More specifically, in this embodiment, the male buckle 2 is a single-piece elongated structure integrally formed, and the male buckle 2 has a positioning section 21 and a travel section 22 connected to the positioning section 21 (bottom edge) and movable along the outer shell 1, and the top of the positioning section 21 is generally triangular, but the present invention is not limited thereto.

[0033] In this embodiment, the top of the positioning segment 21 has two abutment walls 211 and two limiting protrusions 212. The two abutment walls 211 are located on opposite sides of the positioning segment 21 along a width direction W perpendicular to the thickness direction T and the first direction D1, and each abutment wall 211 includes multiple protrusions. The two limiting protrusions 212 are located on opposite sides of the positioning segment 21 along the thickness direction T and are adjacent to the top of the positioning segment 21.

[0034] Furthermore, the stroke segment 22 has two sliders 221, and the two sliders 221 are located on opposite sides of the positioning segment 21 along the thickness direction T. That is, the stroke segment 22 is slidably disposed in the two track grooves 13 by means of the two sliders 221, so that the relative movement stroke between the male buckle 2 and the outer shell 1 can be accurately controlled.

[0035] In this embodiment, the female buckle 3 is a single-piece tubular structure integrally formed, and the female buckle 3 has two positioning inner walls 31, and the distance between the two positioning inner walls 31 gradually decreases along the first direction D1 (or along the direction away from the first opening 11). In this embodiment, each positioning inner wall 31 is generally stepped or serrated, but the present invention is not limited to this.

[0036] Furthermore, the two positioning inner walls 31 are located on opposite sides of the positioning segment 21, jointly defining two rope-passing channels C for the two control segments 301 to pass through. In this embodiment, the two control segments 301 of the rope 300 pass through the two rope-passing channels C from the second opening 12 and exit from the first opening 11, so that the two rope tails 302 are located outside the buckle assembly 100.

[0037] It should be further noted that, in other embodiments of the present invention not illustrated, the female buckle 3 may employ at least one positioning inner wall 31 according to actual needs, and at least one positioning inner wall 31 is located on at least one side of the positioning segment 21 to collectively define at least one of the rope-threading channels C. Furthermore, at least one of the control segments 301 passes through at least one of the rope-threading channels C from the second opening 12 and exits from the first opening 11.

[0038] More specifically, in this embodiment, the two pressure walls 211 are spaced apart (or face) the two positioning inner walls 31 along the width direction W, respectively, to jointly define two rope-threading channels C. That is, each pressure wall 211 faces one positioning inner wall 31 to jointly define one rope-threading channel C.

[0039] It should be noted that, since each of the control segments 301 requires a large space in the corresponding rope-threading channel C when it is inserted into the corresponding rope-threading channel C, the space required in the rope-threading channel C is relatively small when each of the control segments 301 is located within the corresponding rope-threading channel C and needs to adjust the tension of the rope 300. Therefore, in this embodiment, the female buckle 3 and the male buckle 2 can further precisely control the space of the rope-threading channel C through structural cooperation, but are not limited thereto.

[0040] Specifically, the female buckle 3 has two movable grooves 32 adjacent to the second opening 12, and two buffer grooves 33 respectively adjacent to the two movable grooves 32. In this embodiment, the two movable grooves 32 are recessed from the second opening 12 along the second direction D2 and are formed on the inner edge of the female buckle 3, and face each other along the thickness direction T. The two buffer grooves 33 are perforated and correspond to each other along the thickness direction T, and the two buffer grooves 33 are located on the side of the two movable grooves 32 away from the second opening 12.

[0041] Accordingly, as shown in Figures 5 and 6, when the female buckle 3 is inserted into the outer shell 1 through the second opening 12 along the second direction D2, the two limiting protrusions 212 of the male buckle 2 can be respectively disposed in the two buffer grooves 33 to be located in a rope threading position, so that the buckle assembly 100 can be used to allow the two control sections 301 to be inserted therein.

[0042] Furthermore, as shown in Figures 5 to 8, when the female buckle 3 is inserted into the outer casing 1 through the second opening 12 along the second direction D2 and is located at the rope threading position, the two limiting protrusions 212 of the male buckle 2 can pass over the two buffer grooves 33 and be respectively disposed in the two movable grooves 32 to be in a usage position, so that the buckle assembly 100 can be used to perform a locking operation and an unlocking operation of the rope 300. That is to say, the male buckle 2 and the female buckle 3 can change from the rope threading position to the usage position by moving relative to each other within the outer casing 1.

[0043] Furthermore, the inner diameter of the buckle assembly 100 when it is in the rope threading position is larger than that in the use position. Therefore, the buckle assembly 100 in the rope threading position is more convenient for the manufacturer to ship and distribute, so that the user can easily thread the two control sections 301 into the two rope threading channels C, and then move the buckle assembly 100 from the rope threading position to the use position. However, the present invention is not limited thereto.

[0044] For example, in other embodiments of the present invention not shown, the buckle assembly 100 may also skip the rope threading position according to actual needs; that is, when the female buckle 3 is threaded through the second opening 12 along the second direction D2 into the outer shell 1, the two limiting protrusions 212 of the male buckle 2 can pass over the two buffer grooves 33 and be respectively set in the two movable grooves 32 to be in the use position, so that the buckle assembly 100 can be used to perform the locking operation and the unlocking operation.

[0045] As shown in Figures 9 and 10, each of the control segments 301 can generate tension, and the fastener assembly 100 (e.g., the female buckle 3) can be subjected to force to perform the locking operation. During the locking operation, when the outer shell 1 is gripped and pushed along the first direction D1, the male buckle 2 moves along the second direction D2, and the two control segments 301 generate tension, forcing the male buckle 2 to move relative to the female buckle 3 and the outer shell 1 in another direction (e.g., the first direction D1) to reduce the inner diameter of each of the rope passages C.

[0046] Furthermore, as shown in Figure 11, the outer casing 1 can be gripped and pulled along the second direction D2 to perform the unlocking operation. During the unlocking operation, the male buckle 2 connected to the outer casing 1 moves relative to the female buckle 3 (e.g., the outer casing 1 and the male buckle 2 move relative to the female buckle 3 along the second direction D2) to enlarge the inner diameter of each of the rope-threading channels C. During the unlocking operation, the ends of the two track grooves 13 of the outer casing 1 abut against the two sliders 221 of the male buckle 2 and move synchronously along the second direction D2, and a portion of the female buckle 3 protrudes from the second opening 12 of the outer casing 1.

[0047] As described above, in this embodiment, the wearable device 1000 (or the cord adjustment mechanism) can achieve both the tightening and unlocking operations by applying force to the outer shell 1 through the structural cooperation between the outer shell 1, the male buckle 2, and the female buckle 3, thereby facilitating user operation. Furthermore, the tightening operation is achieved by utilizing the tension of the cord 300 through the structural cooperation between the outer shell 1, the male buckle 2, and the female buckle 3.

[0048] [Example 2]

[0049] Please refer to Figures 12 to 16, which illustrate Embodiment Two of the present invention. Since this embodiment is similar to Embodiment One described above, the similarities between the two embodiments will not be repeated (e.g., the object and the rope). The differences between this embodiment and Embodiment One are roughly explained as follows:

[0050] In this embodiment, the fastener assembly 100 includes a tubular outer shell 1, a male buckle 2 passing through the outer shell 1, and a female buckle 3 passing through the outer shell 1 and assembled to the male buckle 2. Furthermore, in this embodiment, the fastener assembly 100, through the structural cooperation between the outer shell 1, the male buckle 2, and the female buckle 3, can be made without any metal springs, thereby achieving a metal-free fastener assembly 100 and facilitating recycling operations.

[0051] It should be noted that, compared with Embodiment 1, the outer shell 1, the male buckle 2, and the female buckle 3 disclosed in this embodiment have roughly the same structure, connection relationship, and operation. The main difference lies in their shapes (e.g., the female buckle 3 extends through opposite ends of the outer shell 1) and the male buckle 2 further has two swing arms 23 extending from the positioning section 21 (e.g., the top bottom edge of the positioning section 21), and the two swing arms 23 are respectively located on opposite sides of the stroke section 22. The two swing arms 23 can swing against the two control sections 301, thereby enabling the two control sections 301 to be more stably configured in the buckle assembly 100.

[0052] It should be noted that, in other embodiments of the present invention not illustrated, the male buckle 2 may also employ at least one of the swing arms 23 as required by actual needs, and at least one of the swing arms 23 is located on at least one side of the stroke segment 22, so that at least one of the swing arms 23 can swing against at least one of the control segments 301.

[0053] Accordingly, at least one of the control segments 301 can generate tension, and the male buckle 2, under force, moves away from the rope tail end 302 relative to at least one of the control segments 301 to perform the locking operation. During the locking operation, when the outer shell 1 is gripped and pushed along the first direction D1, the male buckle 2 moves relative to the outer shell 1 in the opposite direction D2, and at least one of the control segments 301 generates tension, forcing the male buckle 2 to move relative to the female buckle 3 and the outer shell 1 along the first direction D1 to reduce the inner diameter of at least one of the rope passages C.

[0054] Furthermore, the outer casing 1 can be gripped and pulled along the second direction D2, and the outer casing 1 can be moved relative to at least one of the control sections 301 toward the rope tail end 302 by force to perform the unlocking operation. During the unlocking operation, the male buckle 2 connected to the outer casing 1 moves relative to the female buckle 3 along the second direction D2 to enlarge the inner diameter of at least one of the rope threading channels C.

[0055] [Technical Effects of the Embodiments of the Invention]

[0056] In summary, the wearable device and cord adjustment mechanism disclosed in this invention, through the structural cooperation between the outer shell, the male buckle, and the female buckle, allow both the tightening and unlocking operations to be performed by applying force to the outer shell, thereby facilitating user operation. Furthermore, the tightening operation of the cord adjustment mechanism is further achieved by utilizing the tension of the cord through the structural cooperation between the outer shell, the male buckle, and the female buckle.

[0057] Furthermore, the wearable product and cord adjustment mechanism disclosed in this embodiment of the invention can further precisely control the space of the cord threading channel through the structural cooperation of the female buckle and the male buckle. That is to say, the inner diameter of the buckle assembly when it is in the cord threading position is larger than that in the usage position. Therefore, the buckle assembly in the cord threading position is more convenient for the manufacturer to ship and distribute, so that the user can easily thread at least one of the control sections into at least one of the cord threading channels, and then move the buckle assembly from the cord threading position to the usage position.
