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 across the entire wire that functions as a shoelace, thereby smoothly tightening the shoe as a whole.

[0002] Most shoes are designed to be tightened with laces or zippers to prevent them from becoming loose on the user's feet when 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] Additionally, various materials are used to create various shapes, and due to the characteristics of these materials, there is a problem that the knots are not strong and easily come undone.

[0006] Taking this into account, a number of guide devices are known that change and guide the direction of 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 provides 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 provides a shoe wire guide device characterized by including: a fixing part having a lower surface facing the upper of the shoe; and a guide part built into the fixing part, penetrating the fixing part to bring the upper and the user's foot into close contact, thereby changing and guiding the direction of a wire that tightens the shoe.

[0012] Here, the fixing part is characterized in that it includes a hollow body having a lower surface facing the upper skin and through which the wire passes, a wire passage slot penetrating through both sides of the body and communicating with the internal space of the body and 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 built into the body.

[0013] At this time, 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.

[0014] In addition, the fixing part is characterized in that it further includes a support hole formed in a circular block shape in the inner bottom surface of the hollow main body, an installation slot formed in a predetermined shape penetrating from one edge of the support hole toward the distal end of the fixing piece connected to the main body through the front end of the fixing piece, a prevention piece that protrudes from the distal edge of the installation slot toward the support hole with respect to the front end of the installation slot connected to the support hole and allows elastic deformation and restoration, and a detachment prevention slope that protrudes slantedly from one side of the upper surface of the prevention piece toward the distal end with respect to the front end of the prevention piece connected to the distal edge of the installation slot.

[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.

[0062] First, the present invention can be applied to an embodiment including a guide part (200) built into a fixing part (100) having a lower surface (101, see FIG. 4 below) facing the upper surface of a shoe (not shown below) as shown in FIGS. 1 to 4.

[0063] 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.

[0064] At this time, the fixed parts (100) can be arranged in multiple numbers on both front sides of the upper skin.

[0065] The present invention can be applied to the above-described embodiments, and of course, the following various embodiments can also be applied.

[0066] First, the fixed part (100) may include a hollow body (110) having a lower surface (101) facing the upper skin and through which a wire (300) passes, a wire passage slot (111) penetrating through both sides of the body (110) and communicating with the internal space of the body (110) through which the wire (300) passes, and a fixed piece (120) extending from one edge of the body (110) and fixed to the upper skin.

[0067] Here, it can be seen that the guide part (200) to be described later is built into the main body (110).

[0068] At this time, the fixed part (100) may further have 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.

[0069] 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.

[0070] The aforementioned fixed piece (120) may be extended and bent from the main body (110) to fit the outer shape of the upper skin to be fixed.

[0071] 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.

[0072] Meanwhile, the fixed part (100) may further include a support hole (112) formed in a circular block shape in the inner bottom surface of the hollow body (110).

[0075] In addition, the fixed part (100) may further include a detachment prevention slope (132) that is formed to protrude slantedly from one side of the upper surface of the prevention piece (131) toward the distal end, with respect to the leading end of the prevention piece (131) connected to the distal edge of the installation slot (130).

[0076] The prevention piece (131) and the anti-separation slope (132) are provided to prevent the wire (300) functioning as a shoelace from being separated from the main body (110) when the wire (300) is being moved or worked before being inserted through the wire passage slot (111).

[0077] In addition, the ends of each of the anti-separation piece (131) and the anti-separation slope (132) are formed to face the outer surface of the roller (230), so that together with the anti-separation step (240) described later, the wire (300) guided to the roller (230) is regulated and guided so that it does not come off from the roller (230).

[0078] 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).

[0079] 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).

[0080] 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).

[0081] 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).

[0082] 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).

[0083] 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).

[0084] 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).

[0085] 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.

[0086] 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.

[0087] 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.
