First Embodiment

[0026] Referring to FIG. 1 to FIG. 10, a first embodiment of the present disclosure provides a zipper head assembly structure Z, including a sliding element 1, an elastic element 2 and a pulling element 3.

[0027] Firstly, referring to FIG. 1 to FIG. 5, the sliding element 1 (or a zipper head) includes a first sliding portion 11, a second sliding portion 12 corresponding to the first sliding portion 11, a connection portion 13 connected between the first sliding portion 11 and the second sliding portion 12, two riveted portions 14 disposed on the first sliding portion 11, and two stop portions 15 respectively adjacent to the two riveted portions 14. For example, the first sliding portion 11 has a first end portion 111 suspended therefrom and a second end portion 112 opposite to the first end portion 111 of the first sliding portion 11, and the second sliding portion 12 has a first end portion 121 suspended therefrom and a second end portion 122 opposite to the first end portion 121 of the second sliding portion 12. In addition, the first end portion 111 of the first sliding portion 11 corresponds to the first end portion 121 of the second sliding portion 12, and the connection portion 13 is connected between the second end portion 112 of the first sliding portion 11 and the second end portion 122 of the second sliding portion 12. However, the aforementioned description for the sliding element 1 is merely an example and is not meant to limit the scope of the present disclosure.

[0028] Moreover, referring to FIG. 1 to FIG. 5, the elastic element 2 is disposed on the sliding element 1, and the elastic element 2 includes a retaining portion 21 retained by the connection portion 13, a movable portion 22 movably passing through the first sliding portion 11, and an elastic portion 23 connected between the retaining portion 21 and the movable portion 22. For example, the first sliding portion 11 has a through opening 110, the movable portion 22 of the elastic element 2 movably passes through the through opening 110 of the first sliding portion 11, and the two riveted portions 14 are respectively disposed beside two opposite sides of the through opening 110. However, the aforementioned description for the elastic element 2 is merely an example and is not meant to limit the scope of the present disclosure.

[0029] Furthermore, referring to FIG. 1 to FIG. 5, the pulling element 3 includes a pivot portion 31 movably disposed on the first sliding portion 11 and two abutting portions 32 respectively connected to two opposite sides of the pivot portion 31, and the pivot portion 31 includes two pivot sections 311 respectively pivotally mated with the two riveted portions 14, and an abutting section 312 connected between the two pivot sections 311. For example, the abutting section 312 has a concave region 3121 formed between the two pivot sections 311 and an abutting region 3122 outwardly extended from the concave region 3121. However, the aforementioned description for the pulling element 3 is merely an example and is not meant to limit the scope of the present disclosure.

[0030] More particularly, referring to FIG. 1, FIG. 3 and FIG. 6 to FIG. 8, when the pulling element 3 has not been moved relative to the sliding element 1 yet and is substantially horizontally placed on the first sliding portion 1, the elastic portion 23 of the elastic element 2 can downwardly abut against the abutting section 312 of the pivot portion 31 of the pulling element 3. That is to say, when the pulling element 3 has not been moved relative to the sliding element 1 yet and is substantially horizontally placed on the first sliding portion 11, the elastic portion 23 of the elastic element 2 can downwardly abut against the concave region 3121 of the abutting section 312, and the elastic portion 23 of the elastic element 2 can be partially received inside the concave region 3121 of the abutting section 312. In addition, referring to FIG. 9 and FIG. 10, when the pulling element 3 has been moved relative to the sliding element 1 so as to make the pulling element 3 substantially perpendicular to the first sliding portion 11 (that is to say, the pulling element 3 shown as a horizontal state can be changed into the pulling element 3 shown as a vertical state by pulling the pulling element 3 up), the abutting section 312 of the pivot portion 31 of the pulling element 3 can upwardly abut against the elastic portion 23 of the elastic element 2, and the two abutting portions 32 of the pulling element 3 can respectively abut against the two stop portions 15, so that the pulling element 3 is blocked or restricted by the two stop portions 15 and cannot be moved forwardly. In other words, when the pulling element 3 has been moved relative to the sliding element 1 so as to make the pulling element 3 substantially perpendicular to the first sliding portion 11, the abutting region 3122 of the abutting section 312 can upwardly abut against the elastic portion 23 of the elastic element 2, so that an end portion of the movable portion 22 can be received inside the through opening 110.

[0031] For example, referring to FIG. 1 to FIG. 5, one of the two riveted portions 14 includes two first bending sections 141 correspondingly disposed on the first sliding portion 11, and one of the two pivot sections 311 of the pivot portion 31 is partially covered or enclosed by the two first bending sections 141 so as to restrict the pulling element 3 and prevent the pulling element 3 from being separated from the sliding element 1 (that to say, the pulling element 3 does not escape from the sliding element 1). In addition, another one of the two riveted portions 14 includes two second bending sections 142 correspondingly disposed on the first sliding portion 11, and another one of the two pivot sections 311 of the pivot portion 31 is partially covered by the two second bending sections 142 so as to restrict the pulling element 3 and prevent the pulling element 3 from being separated from the sliding element 1 (that to say, the pulling element 3 does not escape from the sliding element 1). Therefore, by virtue of the two first bending sections 141 of one of the two riveted portions 14 being mated with one of the two pivot sections 311 of the pivot portion 31 and the two second bending sections 142 of another one of the two riveted portions 14 being mated with another one of the two pivot sections 311 of the pivot portion 31, the pulling element 3 can be pivotally disposed on the first sliding portion 11. However, the aforementioned description for the riveted portion 14, the first bending section 141 and the second bending section 142 is merely an example and is not meant to limit the scope of the present disclosure.

[0032] It should be noted that one of the two stop portions 15 is tightly connected to one of the two first bending portions 141, and another one of the two stop portions 15 is tightly connected to one of the two second bending portions 142 as shown in FIG. 1, FIG. 3, and FIG. 5 to FIG. 7.

[0033] For example, referring to FIG. 1 and FIG. 3, the stop portion 15 has an inner curved surface 1501 and an outer curved surface 1502 opposite to the inner curved surface 1501, the first bending section 141 has a first inner curved surface 1411 and a first outer curved surface 1412 opposite to the first inner curved surface 1411, and the second bending section 142 has a second inner curved surface 1421 and a second outer curved surface 1422 opposite to the second inner curved surface 1421. In addition, a contour of the inner curved surface 1501 of one of the two stop portions 15 is substantially the same to and partially flush with a contour of the first inner curved surface 1411 of one of the two first bending sections 141, and a contour of the inner curved surface 1501 of another one of the two stop portions 15 is substantially the same to and partially flush with a contour of the second inner curved surface 1421 of one of the two second bending sections 142. Moreover, a contour of the outer curved surface 1502 of one of the two stop portions 15 is substantially the same to a contour of the first outer curved surface 1412 of one of the two first bending sections 141, and a contour of the outer curved surface 1502 of another one of the two stop portions 15 is substantially the same to a contour of the second outer curved surface 1422 of one of the two second bending sections 142. However, the aforementioned description for the stop portion 15, the first bending section 141 and the second bending section 142 is merely an example and is not meant to limit the scope of the present disclosure.

[0034] For example, referring to FIG. 6 and FIG. 7, a width W of a bottom side of the stop portion 15 is smaller than a width W1 of a bottom side of the first bending section 141 and a width W2 of a bottom side of the second bending section 142, and a height H of the stop portion 15 is smaller than a height H1 of the first bending section 141 and a height H2 of the second bending section 142. However, the aforementioned description for the stop portion 15, the first bending section 141 and the second bending section 142 is merely an example and is not meant to limit the scope of the present disclosure.

Second Embodiment

[0035] Referring to FIG. 11, a second embodiment of the present disclosure provides a zipper head assembly structure (not labeled) and a sliding element 1 thereof. Comparing FIG. 11 with FIG. 5, the difference between the second embodiment and the first embodiment is as follows: in the second embodiment, one of the two stop portions 15 is separate from and adjacent to one of the two first bending portions 141, and another one of the two stop portions 15 is separate from and adjacent to one of the two second bending portions 142. That is to say, one of the two stop portions 15 can be tightly connected to one of the two first bending portions 141 (such as in the first embodiment as shown in FIG. 5) or can be separated from and adjacent to one of the two first bending portions 141 (such as in the second embodiment as shown in FIG. 11), and another one of the two stop portions 15 can be tightly connected to one of the two second bending portions 142 (such as in the first embodiment as shown in FIG. 5) or can be separated from and adjacent to one of the two second bending portions 142 (such as in the second embodiment as shown in FIG. 11), according to different requirements.

[0036] In conclusion, by virtue of the sliding element 1 including a first sliding portion 11, two riveted portions 14 disposed on the first sliding portion 11, and two stop portions 15 respectively adjacent to the two riveted portions 14 and the pulling element 3 including a pivot portion 13 movably disposed on the first sliding portion 11 and two abutting portions 32 respectively connected to two opposite sides of the pivot portion 31, when the pulling element 3 has been moved relative to the sliding element 1 so as to make the pulling element 3 substantially perpendicular to the first sliding portion 11, the two abutting portions 32 of the pulling element 3 respectively abut against the two stop portions 15, so that the pulling element 3 can be blocked or restricted by the two stop portions 15.

[0037] Furthermore, by virtue of the two riveted portions 14 being disposed on the first sliding portion 11 and the two stop portions 15 being respectively adjacent to the two riveted portions 14, when the pulling element 3 has been moved relative to the sliding element 1 so as to make the pulling element 3 substantially perpendicular to the first sliding portion 11, the two abutting portions 32 of the pulling element 3 respectively abut against the two stop portions 15, so that the pulling element 3 can be blocked or restricted by the two stop portions 15.

[0038] The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

[0039] The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope.
