Description

Wire guide device for shoes

[0001] The present invention relates to a wire guide device for shoes, and more particularly, to a wire guide device for shoes that generates uniform tension throughout the entire wire that functions as a shoelace, thereby smoothly tightening the shoe as a whole.

[0002] Normal shoes are designed to be fastened with shoelaces or zippers to prevent them from becoming loose on the user's feet while they are worn.

[0003] In particular, shoelaces are more commonly used than zippers in sneakers because they can be tightened or loosened to the desired tightness.

[0004] However, if a user exercises or continuously walks while wearing shoes with tied shoelaces, the resulting shock is transmitted to the knots of the shoelaces, causing them to loosen and come undone on their own. This has the disadvantage of causing the shoelaces to loosen and become untied.

[0005] In general, the laces (wires) of shoes and other items are tied by hand by the wearer.

[0006] Since tying your shoelaces by hand like this is inconvenient, many guide devices have been introduced recently that change and guide the direction of the shoelaces when tying them.

[0007] However, since these existing guide devices simply guide the shoelaces in a round shape, there was a problem that the shoelaces could not be tightened smoothly during operation due to friction.

[0008] In particular, these existing guide devices had fatal problems such as not being able to transmit uniform tension to the entire shoelace, causing it to be loose in some sections and excessively tight in others, leading to it breaking.

[0009] (Patent Document 1) Publication No. 10-2024-0082067

[0010] The present invention was invented to improve the above-mentioned problems, and to provide a shoe wire guide device that generates uniform tension across the entire wire that functions as a shoelace, thereby enabling the shoe to be smoothly tightened as a whole.

[0011] In order to achieve the above object, the present invention can provide a shoe wire guide device characterized by including a fixing part having a lower surface facing the upper of the shoe and fixed to the upper; and a guide part built into the fixing part to change and guide the direction of a wire that penetrates the fixing part and closes the upper and the user's foot to fasten the shoe.

[0012] Here, the fixing part includes a hollow body having a lower surface facing the upper skin and having open sides through which the wire passes, and a fixing piece extending from one edge of the body and fixed to the upper skin, and the guide part is characterized in that it is built into the body.

[0013] At this time, the main body includes a first piece having the lower surface in contact with the upper skin, a second piece formed protruding from an edge of one end of the first piece, a third piece formed protruding from an edge of the other end of the first piece, and a fourth piece connecting upper edges of each of the second piece and the third piece, and the upper surface of the first piece forms an inner bottom surface of the main body, while the lower surface of the fourth piece forms an inner ceiling surface of the main body, and a part of the guide portion is rotatably supported between the inner bottom surface of the main body and the inner ceiling surface of the main body.

[0014] In addition, the fixed piece is characterized in that it is fixed by sewing to the upper, by heat-sealing to the upper, or by being fixed by a rivet that penetrates through a riveting hole formed through the fixed piece.

[0015] In addition, the guide part is characterized in that it includes an upper rotation block formed in a shape corresponding to a support groove formed in a circular block shape in the inner ceiling surface of the hollow main body among the fixed parts and rotationally supported by the support groove, a lower rotation block formed in a shape corresponding to a support hole formed in a circular block shape through the inner bottom surface of the hollow main body and rotationally supported by the support hole, an upper surface to which the lower surface of the upper rotation block is fixed, a lower surface to which the upper surface of the lower rotation block is fixed, a roller having an outer circumference facing the outer surface of the wire and rotatable in the inner space of the fixed part, and a separation prevention step formed protruding along the outer circumferences of the upper and lower ends of the roller to prevent the wire from being separated from the roller.

[0016] According to the present invention having the above configuration, it has the special advantage of being able to smoothly tighten the shoe as a whole by generating uniform tension throughout the wire functioning as a shoelace.

[0063] In addition, FIG. 5 is a conceptual diagram showing the internal structure of a wire guide device of a shoe according to various embodiments of the present invention, which is an enlarged view of part v of FIG. 4(a) and FIG. 4(b).

[0064] First, the present invention can be applied to an embodiment that includes a guide part (200) built into a fixing part (100) that is fixed to the upper part (not shown below) of a shoe and has a lower surface (101, see FIG. 4 below) facing the upper part of the shoe as shown in FIGS. 1 to 4.

[0065] Here, the guide part (200) is provided to change and guide the direction of the wire (300) that penetrates the fixed part (100) and brings the upper and the user's foot (not shown) into close contact with each other to tighten the shoe.

[0066] At this time, the fixed parts (100) can be arranged in multiple numbers on both front sides of the upper skin.

[0067] The present invention can be applied to the above-described embodiments, and of course, the following various embodiments can also be applied.

[0068] First, the fixed part (100) may include a hollow body (110) having a lower surface (101) facing the upper skin and having open sides through which a wire (300) passes, and a fixed piece (120) extending from one edge of the body (110) and fixed to the upper skin.

[0069] Here, it can be seen that the guide part (200) to be described later is built into the main body (110).

[0070] At this time, the main body (110) may include a first piece (1101) having a lower surface that contacts the upper skin, a second piece (1102) formed to protrude from one end edge of the first piece (1101), a third piece (1103) formed to protrude from the other end edge of the first piece (1101), and a fourth piece (1104) that interconnects the upper edges of each of the second piece (1102) and the third piece (1103).

[0071] The upper surface of the first piece (1101) forms the inner bottom surface of the main body (110), and the lower surface of the fourth piece (1104) forms the inner ceiling surface of the main body (110). It can also be seen that a part of the guide portion (200) to be described later is rotatably supported between the inner bottom surface of the main body (110) and the inner ceiling surface of the main body (110).

[0072] Meanwhile, the fixed part (100) may further include a riveting hole (121) formed through the fixed piece (120) and through which a rivet is fixed to fix the fixed part (100) to the upper skin.

[0073] These riveting holes (121) may include a penetration portion (1211) having a diameter of a certain size that penetrates from the upper surface to the lower surface of the fixed plate (120), and a catch step portion (1212) that is formed recessed from the upper surface of the fixed plate (120) at a step from the upper edge of the penetration portion (1211) so that the head of the rivet (not shown) is caught and fixed.

[0074] The aforementioned fixed piece (120) may be extended and bent from the main body (110) to fit the outer surface shape of the upper part to be fixed.

[0075] That is, the fixed piece (120) may be formed in a shape as shown in (a) of FIGS. 1, 2 and 4 and may be fixed by heat fusion or sewing to the outer surface of the upper skin, and of course, may be fixed to the upper skin by a rivet (not shown) that penetrates through the aforementioned riveting hole (121) as shown in (b) of FIGS. 1 to 4.

[0076] Meanwhile, the fixed part (100) may further include an assembly step part (111, see FIGS. 1 and 3 below) that is cut off from one edge of the upper surface of the first piece (1101) and communicates with the support hole (112) so that the lower rotation block (220) is guided to be inserted into the support hole (112).

[0077] Here, the fixed part (100) may further include a mounting slot (114) in the shape of a long hole cut from one edge of the support hole (112) with a width equal to the diameter of the support hole (112) so that the lower rotation block (220) can be smoothly inserted into the support hole (112) from the assembly step (111).

[0078] At this time, the fixing slot (114) formed in a long hole shape is provided for the convenience of assembling the main body (110) of the guide part (200) including the lower rotation block (220), and it goes without saying that in actual mass production, it can be designed and manufactured with only a circularly formed support hole (112).

[0079] Meanwhile, the guide part (200) may include an upper rotation block (210) formed in a shape corresponding to a support groove (113) formed in a circular block shape in the inner ceiling surface of the hollow main body (110) of the fixed part (100) and rotatably supported by the support groove (113).

[0080] In addition, the guide part (200) may include a lower rotation block (220) formed in a shape corresponding to a support hole (112) formed in a circular block shape through the inner bottom surface of the hollow body (110) and rotatably supported by the support hole (112).

[0081] In addition, the guide part (200) may include a roller (230) that has an upper surface to which the lower surface of the upper rotation block (210) is fixed, a lower surface to which the upper surface of the lower rotation block (220) is fixed, and an outer surface facing the outer surface of the wire (300) and can rotate in the inner space of the fixed part (100).

[0082] In addition, the guide part (200) may include a separation prevention step (240) that is formed protruding along the outer surface of the upper and lower ends of the roller (230) to prevent the wire (300) from being separated from the roller (230).

[0083] That is, the upper rotation block (210) is rotationally supported by a support groove (113) formed sunken into the lower surface of the fourth piece (1104), and the lower rotation block (220) is rotationally supported by a support hole (112) formed through the upper surface of the first piece (1101).

[0084] Meanwhile, the guide part (200) may further include at least one receiving chamber (250) formed toward the center of the support groove (113) on the inner ceiling surface of the main body (110) as shown in FIG. 5 and communicating with the support groove (113).

[0085] In addition, the guide portion (200) may further include a fixed sheet protrusion (251) protruding from the end surface of the receiving chamber (250) with respect to the front end of the receiving chamber (250) that is connected to the support groove (113).

[0086] In addition, the guide part (200) may further include a spring (260) that is accommodated in the receiving chamber (250) and has an inner surface facing the outer surface of the fixed sheet stone piece (251), and has both ends that contact the outer surface of the upper rotating block (210) and the end surface of the receiving chamber (250) and generates elastic force in the direction of pushing the upper rotating block (210).

[0087] Accordingly, by generating elastic force in the direction in which the spring (260) pushes the upper rotation block (210), the tension in the wire (300) can be further increased, thereby enhancing the fastening effect of the wire (300) that functions as a shoelace.

[0088] As described above, it can be seen that the present invention has as its basic technical idea a wire guide device for shoes that generates uniform tension across the entire wire that functions as a shoelace, thereby enabling the shoe to be smoothly tightened as a whole.

[0089] And, of course, many other modifications and applications are also possible for those with common knowledge in the industry within the scope of the basic technical idea of ​​the present invention.
