[0038] As illustrated, a shoelace tightening device (1) having a shoelace finishing structure according to one embodiment of the present invention is configured to easily loosen or tighten shoelaces of ready-made sneakers, etc., which are provided with shoelace loops (12) or shoelace holes (not numbered in the drawing) to tie shoelaces, and comprises a shoelace (20) connected via one or more shoelace loops (12) or shoelace holes (not numbered in the drawing) formed in a shoe (10), and a length adjusting means (30) having a winding drum (34) in which the shoelace (20) is wound and connected and which is wound or unwound so as to be able to tighten the shoelace by rotation, wherein the winding drum (34) is characterized in that a shoelace finishing knot receiving groove (34-3) is formed at the bottom so that a shoelace (20) introduced to the side via the shoelace loop (12) or shoelace hole is passed through and finished in a knot shape in an assembled state.

[0039] That is, a shoelace tightening device (1) having a shoelace finishing structure according to one embodiment of the present invention is a shoelace tightening device (100) comprising a shoelace (20) connected via one or more shoelace loops (12) or shoelace holes formed in a shoe, and a length adjusting means (30) in which the shoelace (20) is wound and connected inside and which can tighten the shoelace (20) by rotation, wherein the length adjusting means (30) comprises: a bottom housing (32) having a cylindrical receiving portion (32-1) with an open upper portion therein and having a sawtooth shape at the upper end; And it comprises a winding drum (34) which is mounted on the receiving portion (32-1) and has a winding portion (34-1) in which the shoelace (20) is wound or unwound, and a shoelace finishing knot receiving groove (34-3) is formed in the winding portion (34-1) of the winding drum (34) through which the shoelace (20) introduced laterally via the shoelace loop (12) or the shoelace hole passes downward through a through hole (34-2), and a shoelace finishing hole (322) is formed at approximately the center bottom of the cylindrical receiving portion (32-1) of the bottom housing (32) so as to be in communication with the shoelace finishing knot receiving groove (34-3) and in which a finishing knot (21) of the introduced shoelace (20) is formed at the lower portion thereof.

[0040] For reference, the shoelace (20) may be a wire added to the shoelace tightening device (1), but the scope of the present invention need not be limited to one type of wire, and although it is generally referred to as a wire in the claims of the present invention, it is obvious that it can encompass all types of wires and materials. That is, the wire that is the shoelace (20) can be formed of any of a wide variety of polymer or metal materials or combinations thereof that exhibit sufficient axial strength and bendability for the present application. For example, any of a wide variety of solid core wires, solid core polymers, or multifilament wires or polymers that can be woven, braided, twisted, or otherwise configured can be used. The solid or multifilament metal core can be provided with a polymer coating, such as PTFE, known in the art, to reduce friction.

[0041] Here, the example shown shows an example in which the tightening device (1) is provided on a shoe, but it can be applied to various tightening devices that can be used on items such as clothing or accessories, sports equipment, etc. that are worn by tightening wires or strings, such as hats, belts, gloves, bags, water skis, snowboarding, etc.

[0042] In addition, the length adjustment means (30) is configured to further include a winding drum (34) and a rotating housing (35) in addition to the bottom housing (32) and the winding drum (34), as shown in FIG. 3, etc.

[0043] Hereinafter, the length adjustment means (30) of the shoelace tightening device (100) having a shoelace finishing structure according to one embodiment of the present invention will be described in more detail.

[0044] Here, there is no limitation on the type of length adjustment means according to the present invention, and the above four components are essentially included in various length adjustment means. In the case of the present invention, there is no limitation on the type of length adjustment means, and it should be understood that any length adjustment device that includes the essential components is not limited to any length adjustment means.

[0045] More specifically, the length adjustment means (30), as shown in FIG. 3, etc., includes a bottom housing (32) having a length adjustment means fixing part (31) formed on one side, a cylindrical receiving part (32-1) with an open upper part formed inside, and an inlet hole (321) through which a shoelace loop (12) or a shoelace hole is introduced on the side; a winding drum (34) having a winding part (34-1) disposed within the cylindrical receiving part (32-1) and through which a shoelace (20) introduced through the inlet hole (321) is wound or unwound; And it is configured to include a rotating housing (35) that is rotatable with respect to the bottom housing (32) and is axially movably coupled to the winding drum (34) to rotate the winding drum (34), wherein a shoelace finishing knot receiving groove (34-3) is formed in the winding drum (34) through which the introduced shoelace (20) passes downward through a passage hole (34-2), and a shoelace finishing hole (322) is formed in the center bottom of the cylindrical receiving portion (32-1) of the bottom housing (32) so as to be in communication with the shoelace finishing knot receiving groove (34-3) and in which a finishing knot (21) of the introduced shoelace (20) is formed at the lower portion thereof.

[0046] The above-mentioned bottom housing (32) is approximately cylindrical, and has a cylindrical receiving portion (32-1) with an open top formed therein so that a winding drum (34) and a rotating housing (35) can be assembled and received therein, thereby providing a space in which a length adjustment means (30) can operate, and a length adjustment means fixing portion (31) described later is formed on one side so that the length adjustment means (30) can be stably fixed to the shoe (10) as a whole.

[0047] In addition, the upper portion of the floor housing (32) is formed with a sawtooth shape (not shown in the drawing) that is processed to allow only one-way rotation of the rotary housing (35) when engaged with a latch (not shown) of the rotary housing (35) described later. Since the structure of engagement through the sawtooth shape of the floor housing and the latch of the rotary housing is a widely known technology, a detailed description thereof will be omitted.

[0048] Here, in the illustrated example, the bottom housing is shown as having a structure in which the bottom case and the upper tooth shape (which engages with the latch of the rotating housing) are formed as one piece for manufacturing convenience, but it is of course possible for the bottom housing to be formed as a separate form from the fixed housing in which the tooth shape is formed and engages with the rotating housing.

[0049] In addition, an inlet hole (321) is formed on the side of the bottom housing (32) so that a shoelace (20) is introduced and passed through the shoelace loop (12) or shoelace hole.

[0050] That is, as shown, it is preferable that two opposing lead holes (332) are formed on the side of the bottom housing (32) so that two strings of shoelaces can be led in opposite directions through two shoelace loops (12) or two shoelace holes, so that the shoelace (20) can be wound or unwound in the winding portion (34-1) of the winding drum (34).

[0051] In addition, a shoelace finishing hole (322) is formed in the lower center of the cylindrical receiving portion (32-1) of the bottom housing (32) so as to be in communication with the shoelace finishing knot receiving groove (34-3) of the winding drum (34) and to form a finishing knot (21) of the introduced shoelace (20) at the lower portion thereof, so that, as shown in FIGS. 4 and 5a to 5c, even in a fully assembled state of the length adjusting means (30), the shoelace (20) that enters through the inlet hole (321) of the bottom housing (32) and the through hole (34-2) and the shoelace finishing knot receiving groove (34-3) of the winding drum (34) via the shoelace loop (12) or the shoelace hole finally passes through the shoelace finishing hole (322) and is easily finished at the lower side thereof, so that the finishing knot (21) can be neatly completed in a fully assembled state of the length adjusting means (30).

[0052] The above-mentioned winding drum (34), as shown in FIGS. 3 and 4, is provided with a winding portion (34-1) in which two strings of shoelaces (20) are wound or unwound through two opposing inlet holes (321) placed within the receiving portion (32-1) of the bottom housing (32).

[0053] That is, the winding drum (34) is formed of the winding part (34-1) having upper and lower plates (drawing numbers not given) in a cross-sectional shape roughly in the shape of the letter I, and a rotating pillar axis (drawing numbers not given) connecting the upper and lower plates, and two opposing through holes (34-2) are formed in the pillar axis through which two strings of shoelaces (20) introduced at the side pass, and a shoelace finishing knot receiving groove (34-3) communicating with the opposing through holes (34-2) is formed integrally in the pillar axis and the lower plate in a form that is open downward.

[0054] As described above, the shoelace finishing knot receiving groove (34-3) is open at the bottom and communicates with the shoelace finishing hole (322) of the bottom housing (32), and the shoelace (20) that enters through the two inlet holes (332) on the side of the bottom housing (32), the two through holes (34-2) of the winding drum (34), and the shoelace finishing knot receiving groove (34-3) finally passes through the shoelace finishing hole (322) and is finished in the form of a finishing knot (21) at the lower side thereof.

[0055] In this way, after passing through the shoelace finishing hole (322), the finishing knot (21) finished at the lower side is pulled to be positioned within the shoelace finishing knot receiving groove of the winding drum (34) as shown in FIG. 5c when the winding drum is under tension (fully wound), so that the finishing is neatly arranged, and since the finishing knot is made when the length adjustment means (30) is fully assembled, the convenience of use is very excellent, and further, compared to the conventional finishing knot being made at an exposed position at the lower end of the shoe as in the conventional method, the finishing knot is made at the unexposed lower part of the length adjustment means, so that the finishing knot is neatly arranged.

[0056]

[0057] The above-mentioned rotating housing (35) serves as a handle when winding a shoelace, and is rotatably coupled to a bottom housing (32) in the form of a fixed housing and axially movable upward or downward.

[0058] That is, the above-mentioned rotary housing (35) is rotatable relative to the bottom housing (32), and is coupled to the winding drum (34) so ​​as to be axially movable up and down, thereby rotating the winding drum (34). Since the structure of this rotary housing is also a widely known technology, further explanation will be omitted.

[0059] Meanwhile, as shown in FIG. 2, etc., the length adjustment means fixing part (31) is formed on one side of the bottom housing (32) so that the length adjustment means (30) can be stably fixed to the shoe (10) through the tightening device fixing means.

[0060] At this time, it is preferable that the tightening device fixing means be formed with a cable tie receiving portion (311) of approximately square shape within the length adjustment means fixing portion (31), and that the length adjustment means (30) be stably fixed to the shoe (10) by passing the cable tie (40) through two adjacent and opposite shoelace holes (or shoelace loops) and the cable tie receiving portion (311).

[0061] However, if a tightening device fixing means of various forms can be used instead of a cable tie structure as a shoe fixing means of the length adjusting means, the present invention is not limited to that fixing means.

[0062] Although the embodiments of the present invention have been described in detail above, this is an embodiment described so that a person having ordinary knowledge in the technical field to which the present invention pertains can easily practice the present invention, and therefore the technical idea of ​​the present invention should not be interpreted as being limited by the description of the embodiments.

[0063] The present invention relates to a shoelace tightening device having a shoelace finishing structure, and can be widely used by applying it to a tightening device that can be used in various ways not only for shoes, but also for clothing or accessories worn by tightening wires or laces, such as hats, belts, gloves, bags, water skis, snowboarding, and other items, such as sports equipment.
