Description

shoe wire guide device

[0001] The present invention relates to a wire guide device for shoes, and more specifically, to a wire guide device for shoes that generates uniform tension throughout the entire wire functioning as a shoelace, thereby enabling the shoe to be tightened smoothly as a whole, and also effectively separates foreign substances attached to the wire, thereby helping to maintain a clean shoe condition at all times.

[0002] Shoelaces and zippers are provided to ensure that the shoe fits snugly against the user's foot without becoming loose while the user is wearing it.

[0003] In particular, shoelaces are used more frequently than zippers in athletic shoes because they allow the user to tighten or loosen them to their desired level of tightness.

[0004] However, there is a disadvantage that when a user exercises or walks continuously while wearing shoes with laces fastened, the resulting impact is transmitted to the knot of the laces, causing the tightness to loosen and come undone on its own.

[0005] In addition, various materials are used to create various shapes, and due to the characteristics of these materials, there is a problem that the knot is not sturdy and comes undone easily.

[0006] Taking these points into consideration, a number of guide devices are disclosed that change and guide the direction of the shoelaces when tightening them.

[0007] However, since these existing guide devices merely serve to guide the shoelaces in a rounded shape, there was a problem where the laces could not be tightened smoothly during operation due to friction.

[0008] In particular, these existing guide devices had fatal problems, such as the shoelaces being loose in some sections and becoming too tight in others, causing them to break, because uniform tension was not transmitted throughout the entire shoelace.

[0009] Above all, for shoes worn by users who frequently walk off-road, such as hiking boots as well as sneakers, foreign substances such as dirt, fallen leaves, or dust often got on the shoelaces, dirtying the shoes or hindering the tightening of the shoelaces.

[0010] Shoelaces that get dirty like this require troublesome additional measures, such as untying them one by one to wash or shake them out.

[0011] Therefore, there is an urgent need to develop shoes that can smoothly tighten the entire shoe by generating uniform tension across the entire wire functioning as a shoelace.

[0012] Furthermore, there is an urgent need to develop a product that can effectively separate foreign substances from the wire, helping to maintain the shoes in a clean condition at all times.

[0013] (Patent Document 1) Published Patent No. 10-2024-0082067

[0014] The present invention was developed to improve upon the above-mentioned problems and aims to provide a shoe wire guide device that generates uniform tension throughout the entire wire functioning as a shoelace, thereby enabling the shoe to be tightened smoothly as a whole, as well as effectively separating foreign substances attached to the wire to help maintain a clean shoe condition at all times.

[0015] To achieve the above objectives, the present invention may provide a shoe wire guide device characterized by comprising: a fixing part fixed to the upper of the shoe; a wire that tightens the shoe by penetrating the fixing part and bringing the upper part and the user's foot into close contact; a guide part including a roller mounted on the fixing part to change and guide the direction of the wire; and a separation part formed on the fixing part to separate foreign substances attached to the wire penetrating the fixing part from the wire.

[0016] Here, the fixing member comprises a main body having an internal space in which the roller is rotatably mounted and which has a first lower surface that faces the upper and through which the wire passes and which corresponds to the surface shape of the upper, and which is open on both left and right sides, and a fixing member having a second lower surface that extends from the first lower surface and corresponds to the surface shape of the upper, extending from the front of the main body and fixed to the upper, and the fixing member is characterized in that it can be fixed to the upper by sewing.

[0017] At this time, the fixing part comprises a main body having an internal space in which the roller is rotatably mounted and which has a first lower surface that faces the upper and through which the wire passes and which corresponds to the surface shape of the upper, and which is open on both left and right sides; a fixing piece that extends from the front of the main body and has a second lower surface that extends from the first lower surface and corresponds to the surface shape of the upper so as to be fixed to the upper, a through hole that penetrates the fixing piece, and a circular ring-shaped locking step formed protruding along the edge of the through hole, and the fixing part is characterized by being able to be fixed to the upper by a rivet that penetrates the through hole and is locked and fixed to the locking step.

[0018] Additionally, the fixing member comprises a main body having an internal space in which the roller is rotatably mounted and through which the wire passes and which has a first lower surface corresponding to the surface shape of the upper face and which faces the upper face, and which is open on both left and right sides, reinforcing wing pieces extending from both front sides of the main body, and a main reinforcing rib connecting the ends of the reinforcing wing pieces, and the fixing member is characterized by being able to be fixed to the upper face by webbing.

[0019] In addition, the separating part comprises a separating projection formed on the front or rear inner surface among the front and rear inner surfaces of the fixing part, or formed on both the front inner surface and the rear inner surface, with respect to the left and right sides of the fixing part that are open for the wire to pass through, in the fixing part having an internal space in which the roller is mounted, wherein the outer surface of the separating projection faces the outer circumference of the wire that is seated on and guided by the roller.

[0020] According to the present invention with the above-described configuration, the following effects can be achieved.

[0021] First of all, the present invention has the advantage of generating uniform tension throughout the entire wire that functions as a shoelace, thereby allowing the shoe to be tightened smoothly overall.

[0022] In addition, the present invention has the distinctive advantage of helping to maintain a consistently clean shoe condition by immediately separating foreign substances from the wire during the tightening process when foreign substances are attached to the wire.

[0060] In addition, FIG. 5 is a conceptual bottom view showing the overall appearance of a wire guide device for a shoe according to various embodiments of the present invention, and a conceptual partial view showing an enlarged portion of a specific part of the bottom view.

[0061] First, the present invention may apply an embodiment in which a guide part (200) and a separation part (300) are formed on a fixing part (100) that is fixed to the upper of a shoe (not shown below) as shown in FIGS. 1 to 5.

[0062] Here, the guide portion (200) may include a roller (201) mounted on the fixed portion (100) to change and guide the direction of the wire (not shown) that tightens the shoe by penetrating the fixed portion (100) and bringing the upper and the user's foot (not shown) into close contact.

[0063] At this time, the separating part (300) is formed in the fixed part (100) and is provided to perform the function of separating foreign substances attached to the wire penetrating the fixed part (100) from the wire.

[0064] The present invention is applicable to the above-described embodiments, and it goes without saying that it is also applicable to various embodiments as follows.

[0065] First, the fixed part (100) can be fixed to the upper by rivets as in (a) of FIGS. 1 to 4, by sewing as in (b) of FIGS. 1 to 4, or by webbing as in (c) of FIGS. 1 to 4.

[0066] This fixed part (100) may include a main body (110) having an internal space in which a roller (201) is rotatably mounted and which has open left and right sides, and which has a first lower surface (111) that faces the upper surface and has a wire passing through it as in (a) of FIGS. 1 to 4 and corresponds to the surface shape of the upper surface.

[0067] This fixing part (100) may include a fixing piece (120) having a second lower surface (121) that extends from a first lower surface (111) and corresponds to the surface shape of the upper surface, so as to be fixed to the upper surface by extending from the front of the main body (110).

[0068] Here, the fixing part (100) may include a through hole (122) penetrating the fixing piece (120) and a circular ring-shaped locking step (123) protruding along the edge of the through hole (122).

[0069] At this time, the fixed part (100) can be fixed to the upper body by a rivet (not shown below) that passes through the through hole (122) and is fixed by being caught on the catch step (123).

[0070] In addition, the fixed part (100) may include a main body (110) with open left and right sides, having an internal space in which a roller (201) is rotatably mounted and through which a wire passes as in (b) of FIGS. 1 to 4, and a first lower surface (111) that faces the upper surface and corresponds to the surface shape of the upper surface.

[0071] This fixing part (100) may include a fixing piece (120) having a second lower surface (121) that extends from a first lower surface (111) and corresponds to the surface shape of the upper surface, so as to be fixed to the upper surface by extending from the front of the main body (110).

[0072] Here, the fixed part (100) can be fixed to the upper by sewing.

[0073] Meanwhile, the fixed part (100) may include a main body (110) having an internal space in which a roller (201) is rotatably mounted and which has open left and right sides, and which has a first lower surface (111) that faces the upper surface and corresponds to the surface shape of the upper surface through which a wire passes as in (c) of FIGS. 1 to 4.

[0074] This fixed part (100) may include reinforcing wing pieces (130) extending from both sides of the front of the main body (110) and a main reinforcing rib (131) connecting the ends of the reinforcing wing pieces (130).

[0075] Here, the fixed part (100) can be fixed to the upper by webbing.

[0076] Meanwhile, the guide portion (200) is formed in a shape corresponding to a support groove (112) formed in a circular block shape on the inner ceiling surface of the main body (110) which constitutes a fixed portion (100) having open left and right sides and an internal space in which a roller (201) is rotatably mounted, and at the same time may further include an upper rotating block (210) that protrudes from the upper surface of the roller (201) and is rotatably supported in the support groove (112).

[0077] Additionally, the guide portion (200) may further include a lower rotating block (220) that protrudes from the lower surface of the roller (201) and is rotatably supported in the support hole (113), while being formed in a shape corresponding to a support hole (113) formed through the inner bottom surface of the main body (110) in the shape of a circular block.

[0078] Additionally, the guide portion (200) may further include a groove (230) formed by recessing along the outer surface of the roller (201) to have an arc-shaped cross-section, thereby preventing the wire from coming off the roller (201).

[0079] That is, the upper rotating block (210) is rotatably supported in a support groove (112) formed in a recess on the inner ceiling surface of the main body (110), and the lower rotating block (220) is rotatably supported in a support hole (113) formed through the inner bottom surface of the main body (110).

[0080] Meanwhile, the guide portion (200) may further include at least one receiving chamber (250) formed toward the center of the support groove (112) on the inner ceiling surface of the main body (110) as shown in FIG. 6 and communicating with the support groove (112).

[0081] Additionally, the guide portion (200) may further include a fixing sheet protrusion (251) protruding from the end surface of the receiving chamber (250) with respect to the front end of the receiving chamber (250) communicating with the support groove (112).

[0082] Meanwhile, the separating part (300) may include a separating protrusion (300) formed on the front or rear inner surface among the front and rear inner surfaces of the fixing part (100), or formed on both the front inner surface and the rear inner surface, with respect to the left and right sides of the fixing part (100) that are open for a wire to pass through, in the fixing part (100) having an internal space in which a roller (201) is mounted.

[0083] Here, the outer surface of the separating piece (300) can be positioned to face the outer surface of the wire that is seated on and guided by the roller (201).

[0084] At this time, although not specifically illustrated, a modified and applied design may be applied in which a structure in the shape of a protrusion or a saw is repeatedly protruded on the outer surface of the separating piece (300) so that foreign substances attached to the wire during contact with the wire can be separated more effectively.

[0085] As described above, it can be seen that the basic technical concept of the present invention is to provide a shoe wire guide device that generates uniform tension throughout the entire wire functioning as a shoelace, thereby enabling the shoe to be tightened smoothly as a whole, and also effectively separates foreign substances attached to the wire to help maintain a clean shoe condition at all times.

[0086] And, it goes without saying that many other variations and applications are also possible for those skilled in the art within the scope of the basic technical concept of the present invention.
