Description

Shoestring Fixing Apparatus, and Fixing Method of Shoestring using the same, and Shoes including the same}

The present invention is a shoelace fastener for easily fixing the shoelaces in shoes with shoelaces such as sneakers, sneakers, shoes, etc. and improving the appearance of the shoelaces neatly, and a method of fixing the shoelaces using the same And to a shoe using such a shoelace fastener.

In shoes with shoelaces such as sneakers, sneakers, shoes, as shown in FIG. 1, the shoelaces pass through several shoelace holes in the left and right side soles of the shoe, and then exit the holes located at the top of the left and right side soles of the shoe, The left and right shoelaces are tied with a knot over the tongue. If the shoelaces are too long in this way, the shoelaces may not look good due to reasons such as hanging down the road under the side windows, and it is inconvenient to untie the shoelaces and tie them again every time you put on and take off your shoes. There is also a problem, and when washing shoes, there is also the inconvenience of having to untie and retie the shoelaces.

Therefore, in order to improve such a problem, there is a need for a technology capable of fixing the shoelaces to the shoes without tying the shoelaces. In the past, (Patent Document 1) a shoelace fastener as in Korean Patent Publication No. 10-2020-0120363 Existed.

However, the above conventional shoelace fastener has only several shoelace insertion holes formed on the plate, so there was a limit to firmly fixing the shoelace fastener to the shoe or shoelace hole, and the shape of the shoelace insertion hole was not varied. If the material or thickness of the shoelace is changed due to the problem, there is a problem that it has to be purchased separately.

In addition, the method of inserting the shoelace into the shoelace insertion hole is difficult to apply other connection methods other than the method of inserting the shoelace into one shoelace insertion hole and then inserting it again into another shoelace insertion hole. Depending on the diameter, material, and length of the shoelace, there was inevitably a limit to maintaining a fixed state without being released from the shoelace insertion hole.

In particular, when the frictional force between the shoelace and the inner surface of the shoelace insertion hole changes according to the change in the material of the shoelace, it is necessary to improve the shoelace fixing force.

Advantages and features of the present invention, and a method of achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, only the present embodiments make the disclosure of the present invention complete, and the scope of the invention is fully informed to those skilled in the art. It is provided for the purpose of giving, and the invention is only defined by the scope of the claims.

Throughout this specification, the same reference numerals refer to the same or substantially the same corresponding elements.

In this specification, "and/or" includes each and every combination of one or more of the recited items. In the present specification, the singular form also includes the plural form unless otherwise specified in the phrase. Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used with meanings that can be commonly understood by those of ordinary skill in the art. In addition, terms defined in the dictionary are not interpreted ideally or excessively unless explicitly defined specifically.

Unless otherwise defined, the vertical, left, and right directions used in the present specification will be described based on the direction facing the shoelace fastener 100 in FIG. 2 of the present specification.

Referring to Figure 2, the shoelace fastener 100 of the present invention includes a disk-shaped plate 10 and a cylindrical column portion 20 formed at the center of the circle. A through hole 22 through which a shoelace s is inserted is formed in the cylindrical column part 20. A shoelace (s) is inserted into the body 21 of the cylindrical column part 20 to pass through the through hole 22. The through hole 22 refers to the hollow of the cylindrical column part 20, and in the present specification, it is also referred to as a through hole 22 for convenience when referring to the hole through which the column part 20 passes through the disk-shaped plate 10. It is called. In this respect, the through hole 22 is a concept corresponding to other shoelace insertion holes 1, 2, 3, 4, 5, 31, 32, and the like.

The plate may have a disk shape in FIGS. 2 to 3, and may be rectangular or elliptical as in FIGS. 7 and 15, but the shape of the plate is not limited thereto.

For simplicity of explanation, in the present invention by way of example, in the present invention, the plate of the shoelace fastener 100 of the embodiment as shown in FIGS. 2 to 3 is referred to as a disc-shaped plate, and the reference numeral 10 is assigned, as shown in FIGS. 7 or 15. In the embodiment having the same shoelace fastener 200, that is, a T-shaped hole (or an elongated hole having a circular head) 40, a reference numeral 11 is assigned while being referred to as a rectangular plate. Likewise, the above rectangular plate may have an oval or other shape, and more importantly, the shoelace insertion hole of the shoelace fastener has a through hole 22 in the column and various types of insertion holes (1, 2, 3, 4, 5, 31, 32), or whether it also includes a T-shaped hole (or an elongated hole having a circular head) 40 having separate heads and lengths.

In the case of having a T-shaped hole (or an elongated hole having a circular head) 40, since it is not appropriate for the plate to be formed in a completely circular shape, it is exemplarily described herein as a rectangle or an ellipse.

In addition, referring to FIG. 3, a plurality of shoelace insertion holes are formed in the disk-shaped plate 10 of the shoelace fastener 100 of the present invention. In the embodiment of FIG. 3, four insertion holes 1, 2, 3, 4) are formed.

Both the through hole 22 and the insertion hole 1, 2, 3, 4 formed in the shoelace fastener 100 have a disc-shaped shoelace s from the front side to the back side of the disc-shaped plate 10 or vice versa. It is formed to penetrate between both ends of the disk-shaped plate 10 or the pillar 20 so as to pass through the plate 10.

In a preferred embodiment of the present invention, as shown in FIG. 3, the various types of shoelace insertion holes include a cylindrical insertion hole 1 having a diameter larger than the diameter of the pillar portion, and a cylindrical insertion hole having a diameter smaller than the diameter of the pillar portion ( 2), an insertion hole (3) of a general trapezoidal cross-section having a larger vertical/horizontal width than a diameter of the through hole of the column portion, and an insertion hole (4) having an elliptical cross-section that is smaller than the diameter of the through hole of the column portion and stretched to the left and right. It may be formed, and the insertion holes 1 to 4 are all arranged along the periphery of the column part 20 at a substantially the same radial position at the center of the column part 20.

The reason that the size and shape of the insertion hole are all different is that if you repeatedly insert the shoelace(s) into the insertion hole that does not match the size on a small piece of silicone (the shoelace fastener is mainly made of silicone), the shoelaces will be crushed through the narrow insertion hole. Because it becomes convex and convex, a foreign body sensation may occur when worn later. Various insertion holes are formed to select the most suitable insertion hole so that the shoelace (s) can be inserted.

In particular, the insertion hole 4 is thinner and flatter than a general lace, so that it may be suitable for inserting a long string to the side, and it is bent as a whole like the insertion hole 4, and the support for the shoelace can be improved.

4 to 5, the shoelace fastener 100 of the present invention is located in the uppermost shoelace hole among the shoelace holes of the left and right side windows 1100 of the shoe 1000, and the shoelace fastener 100 ) Of the pillar portion 20 is inserted into the shoelace hole of the shoe 1000.

In Figure 5, the right part shows in a perspective perspective view that the pillar portion 20 of the shoelace fastener 100 is inserted into the shoelace hole of the shoe as such.

The left and right shoelaces (s) pass through the through holes 22 from the outside of the shoe 1000 to the inside of the shoe through the shoelace fastener 100 of the present invention inserted into the shoelace hole of the shoe 1000 Pass through and fit between the shoe insole 1300 as in FIG. 11. If shoes are worn in this state, the shoelace(s) is fixed, that is, the shoelace(s) is fixed, that is, the shoelace(s) fall out of the shoe, or the shoelace(s) is the wearer's foot even if there is no separate knot between the shoelace(s) and the shoelace(s) due to the weight of the person It does not change the fit that fixes or holds the shoes so that the shoes do not move.

In addition, since the shoe insole 1300 is usually formed of a material having a considerable thickness for elasticity, a person does not feel a foreign body feeling on the sole of the foot because the shoelace s enters the shoe insole 1300.

Rather, in the conventional invention, a knot is formed between the shoelaces (s) on the inside and outside of the shoe tongue 1200. When such a knot is formed under the shoe tongue 1200, a foreign body feeling on the back of the foot increases significantly when the shoe is worn. There was, in the present invention, since the shoelace (s) is fixed to the shoe insole 1300 by using the shoelace fastener 100, the feeling of foreign body on the back of the foot is fundamentally eliminated.

9, the inner circumferential surface of the through hole 22 of the column part 20 has a plurality of protrusions 23 capable of increasing friction with the shoelace inserted therein and pressing the shoelace within the circular cross-section. It is formed protruding around the inside of the circle. Due to the protrusion 23 as described above, the frictional force between the shoelaces (s) inserted into the through holes 22 and the through holes 22 is increased, and through this, the support force for the shoelaces (s) between the through holes 22 is increased. It is further increased to allow the shoelace (s) to be more stably fixed in the through hole (22).

Such protrusions 23 may also be formed in the insertion holes 1 to 4, but it is particularly suitable to be formed in the circular insertion holes 1 and 2.

In the case of the insertion hole 3, as shown in FIG. 10, it may have a zigzag shape (31, 32). That is, the insertion holes 31 and 32 are formed in a form in which the upward inclined portions 31a and 32a and the downward inclined portions 31b and 32b are repeated, and a shoelace s is formed in the insertion holes 31 and 32. When inserted, the movement of the shoelace is restricted by the bend (for example, the portion where L1 and L3 meet) made by the upward slope and the downward slope, so that the shoelace (s) is separated from the insertion holes (31, 32). It can be effectively prevented.

As can be seen in (a)/(c) and (b)/(d) of FIG. 10, both ends of the insertion hole are inclined upwards (31a), that is, inclined upwards from the bottom in the direction of viewing FIG. In the embodiment 31 in which an additional is formed and a downward inclined portion 31b and an upward inclined portion 31a are repeated between them, and vice versa, both ends are formed as a downward inclined portion 32b and an upward inclined portion 32a is formed between them. ) And the downwardly inclined portion 32b may be repeated.

In addition, as can be seen in (a) of FIG. 10, the horizontal line (L1) connecting the vertices where the upward inclined portion and the downward inclined portion of the insertion hole 31 meet at the top and the inclined line (L2) of the upward inclined portion at the left end. The angle (a) formed by this can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, etc., and the complementary angle (b), that is, the vertical line (L3) that runs at the vertex where the upward and downward slopes meet. ) And the inclined line (L2) is smaller, the steeper the inclination of the upward inclined portion (31a), and a plurality of layers of upward inclined portion (31a) in the insertion hole (31) of relatively the same width (D) A downward inclined portion 31b may be included. That is, as the clearance angle (b) is smaller, the number of wrinkles forming a zigzag within the same width (D) of the insertion hole 31 increases, and conversely, as the clearance angle (b) increases, the number of wrinkles within the same width (D) decreases. do.

Alternatively, when the angle (a) decreases, if the number of wrinkles is the same, the width (D) of the insertion hole 31 increases, and the circumference of the insertion hole 31 and the disk-shaped plate 10 by that amount Since the gap between the circumferential surface is reduced, the likelihood that the shoelace fastener 100 formed of silicone is torn when the shoelace s enters the insertion hole 31 increases.

Figure 6 is to explain a method of using the shoelace fastener 100 according to the present invention, and insert the shoelace (s) into the column portion 20 of the shoelace fastener 100 (Fig. 6a) and this is a shoe ( 1000) and inserted into the shoelace holes of the side windows 1100 on the left and right sides (b of FIG. 6), and the shoelaces s that have passed through the through holes 22 of the pillars 20 are inserted into the shoes 1000. Put it in the insole 1300 and fix it (Fig. 6 c). In this way, if the shoelace is fixed with the shoelace fastener 100 of the present invention, the knot is not separately formed under or above the shoe tongue 1200 on the shoelace s of the shoe 1000, so it looks neat in appearance. Particularly, the feeling of foreign bodies of the wearer of the shoes is greatly reduced (Fig. 6D).

7 shows a shoelace fastener 200 of another embodiment of the present invention. The shoelace fastener 200 has a column part 20 as shown in FIG. 2 on an approximately rectangular plate 11, and the column part 20 is at the center of the circumference of the disk-shaped plate 10 as in FIG. It is not positioned, but is positioned to be deflected on one side of the rectangular plate 11, on the left side in FIG. 7. In addition, in addition to the insertion holes 1 to 4, another circular insertion hole ( 5) is formed. In addition, a T-shaped hole 40 is formed on the right side of the rectangular plate 11, and the T-shaped hole 40 has a head 41 extending left and right and a length 42 extending vertically. have.

In the T-shaped hole 40, a shoelace (s) is pushed into the T-shaped hole 40, as shown in FIG. 14, and after being inserted into the length 42 of the T-shaped hole 40, the direction is changed at the head part 41. It is a configuration that allows you to move. Therefore, the T-shaped hole 40 has a configuration that is completely open front and rear in the rectangular plate 11.

When the shoelace fastener 200 is used, the shoelace s is pushed up and down into the length 42 of the T-shaped hole 40 and rotated again (in the case of the T-shaped insertion hole) in the horizontal direction. It is hung on the head 41 and can be optionally connected to the insertion holes 1 to 5 before or after it. And again, optionally, before or after that, it can be connected to the through hole 22 of the column portion 20 and finally put the shoelaces in the insole to be fixed. In FIG. 14, a shoelace s is connected only to the T-shaped hole 40 and the through hole 22 of the column part 20.

Alternatively, it may be directly connected to the through hole 22 of the column part 20 from the T-shaped hole 40. Conversely, it may be connected to the T-shaped hole 40 immediately after being connected to the through hole 22 of the column part 20. Through this, the shoelace (s) can be fixedly connected to the shoelace fastener 200 more firmly.

The head part 41 may be generally circular or elliptical, as shown in FIG. 7(d). This is referred to as an elongated hole 40 having a circular head in this specification.

Referring to FIG. 12, the length 42 of the T-shaped hole or the elongated hole 40 having a circular head of the shoelace fastener 200 is in the longitudinal direction of the rectangular plate 11 of the shoelace fastener 200. It may be arranged vertically (FIG. 12A, 12C) or parallel thereto (FIG. 12B). In addition, when arranged perpendicular to the length direction of the rectangular plate 11 of the shoelace fixture 200 as above (Figs. 12A, 12C), the head of the elongated hole 40 having the T-shaped hole or a circular head The portion 41 may face the shoelace s (FIG. 12C) or the left and right side windows 1100 of the shoe 1000 (FIG. 12A).

In FIG. 12B, the head 41 is shown in an elliptical shape, but this is also a modification of the elongated hole 40 having a circular head described in the present invention and falls within the scope of the present invention.

As an example, as shown in FIG. 14, the shoelace (s) is connected to both the pillar portion 20 of the shoelace fastener 200 and the elongated hole 40 having the T-shaped hole or a circular head, The pillar portion 20 may be coupled to the shoelace hole at the top closest to 1200.

Specifically, the shoelace (s) is inserted through the through hole (22) in the column portion (20) of the shoelace fastener (200), so that the shoelace (s) is connected to the shoelace fastener, the T-shaped hole or the circular head In the elongated hole 40 having a portion, the shoelaces (s) are pushed into the length portion 42. To this end, the length 42 of the elongated hole 40 having a T-shaped hole or a circular head is opened to the outside of the shoelace fastener 200 as shown in FIG. 7(d) or 15, and It is configured to be able to push the shoelaces (s) by opening the left and right sides of the length portion 42. To this end, the shoelace fastener 200 itself or the elongated hole 40 having the T-shaped hole or circular head may be formed of a flexible material.

In addition, as shown in Fig. 14, the shoelace (s) connected to the T-shaped hole or the elongated hole 40 having a circular head portion is not directly connected to the shoelace hole connected to the column portion 20, and the pillar It is possible to go through a hole other than the shoelace hole connected to the part 20.

That is, the shoelace s connected to the column portion 20 in the shoelace fastener 200 may not be connected to the T-shaped hole or the elongated hole 40 having a circular head in succession.

This is different from the method in which the shoelace (s) connected to the column part 20 is directly connected to the other insertion holes (1, 2, 3, 4) in the shoelace fastener 100 (see b of FIG. 16). .

Referring to FIG. 16A, a state in which the shoelaces (s) are inserted into the disc-shaped plate 10 of the shoelace fastener 100 is schematically illustrated, and in FIG. 16B, the circle of the shoelace fastener 100 It is shown that the shoelaces (s) are connected continuously to the insertion holes (1, 2, 3, 4) of the plate-shaped plate 10 at the same time.

In Fig. 16B, the insertion holes are shown with reference numerals 1, 2, 3, and 4 together. The shoelaces (s) exiting or entering the through holes 22 of the column portion 20 are partially or completely inserted into the insertion holes. This is to indicate that it can be connected continuously.

The connection method of the column portion 20 and the insertion hole (1, 2, 3, 4) of the shoelace (s) of FIG. 16 is the column portion 20 and the insertion hole (1, 2,) of the shoelace fastener 200 It can also be applied to 3, 4, 5).

An exemplary invention for connecting the shoelaces to the pillars 20 and the insertion holes 1, 2, 3, 4 of the shoelace fastener 200 will be described as follows.

As an example of being inserted into only two insertion holes, the left and right shoelaces (s) each pass through the pillar portion 20 from the back side of the disc-shaped plate 10 to the front side, and then through the insertion hole 2 After passing from the front side of the disc-shaped plate 10 to the back side, the insertion hole 1 is passed from the back side to the front side of the disc-shaped plate 10 again, and then it may be fixed in the shoe insole 1300.

In addition, as an example of being inserted only into the three insertion holes, the left and right shoelaces (s) each pass through the pillar portion 20 from the back side to the front side of the disc-shaped plate 10, and then the insertion hole After passing 2 in the direction from the front side to the back side of the disc-shaped plate 10, after passing through the insertion hole 1 in the direction from the back side to the front side of the disc-shaped plate 10, the insertion hole 3 is again passed through the circle. After passing from the front side of the plate-shaped plate 10 to the back side, it may be fixed in the shoe insole 1300.

In addition, as an example to be inserted into the four insertion holes, the left and right shoelaces (s), respectively, after passing through the pillar portion 20 from the back of the disc-shaped plate 10 in the front direction, the insertion hole After passing 2 in the direction from the front side to the back side of the disc-shaped plate 10, after passing through the insertion hole 1 in the direction from the back side to the front side of the disc-shaped plate 10, the insertion hole 3 is again passed through the circle. After passing from the front side of the plate-shaped plate 10 to the rear side, the insertion hole 4 may be again passed from the back side to the front side of the disc-shaped plate 10 and then fixed in the shoe insole 1300.

In addition, as shown in Figure 15, the length 42 of the T-shaped hole (or an elongated hole having a circular head) 40 of the shoelace fastener 200, the length 42 and the head ( 41) can be configured in various forms.

The length portion 42 of FIG. 15A is formed with bends or wrinkles to increase the frictional force that prevents the inserted shoelace s from being separated. 15(b) shows that the length 42 may have an inclination angle with respect to the head 41, so that the head 41 and the length 42 are in a straight line as in FIG. 7(d). It makes it more difficult for the shoelace (s) separated from the head part 41 to escape from the length part 42 compared to the case where it is arranged. Fig. 15(d) shows that the angle is set to 90 degrees. 15 (c) shows the possibility that the shoelaces (s) may be separated from the head part 41 due to the increased width of the head part 41 as the width of the head part 41 is relatively larger. Can be lower than. FIG. 15(e) shows that the length part 42 itself is bent, and as an example, it is bent by 90 degrees, whereby the length part with the head part 41 and the length part without the head part are separated, and the head part Two or more heads are formed in the length portion, and as an example, two heads are formed in (e) of FIG. 15. The two heads and the heads in the length of the head are spaced apart, and the same hole (groove) is formed between them as well as the length 42 through which the shoelaces (s) can pass. Through this, the shoelace (s) passing through the length without the head is selectively passed to any one of the heads, that is, to the length at which the head is located deeply or the length is relatively close to the length without the head, optionally shoes You can hang the string.

The shoelace fastener 200 of FIGS. 7 and 15 may be implemented as in FIGS. 17 to 18 without the insertion hole 5.

In addition, the shoelace fastener 200 of FIGS. 7 and 15 is not formed in the pillar portion 20 including the body 21, the through hole 22 as in FIG. 19, but a rectangular plate 11 and a flat height It can be formed at the same height as other insertion holes (1, 2, 3, 4, 5). In this case, since the column portion 20 is omitted, the coupling force with the shoelace hole is slightly lowered, but the shoelace fastener 200 is easily detached from the shoe 1000 by that amount.

7, 15, 17 to 19, that is, the connection method of the shoelace (s) in the shoelace fastener 200 employing a rectangular plate 11 is illustrated in FIG. 12 or 14 As shown, the shoelace (s) entering and exiting the shoelace hole at the top of the shoe 1000 is connected to the through hole 22, and the shoelace (s) entering and exiting the shoelace hole immediately before it is T It is connected to a shaped hole (or an elongated hole having a circular head) 40. That is, the last shoelace (s) is connected to the through hole 22 of the column part 20 or the through hole 22 of FIG. 19 without the column part, and the shoelace (s) immediately before the last shoelace (s) is a length part It is a form that is pushed to 42 and hooked onto the head 41.

The shoelace (s) passing through the through hole (22) is an insertion hole according to the length of the shoelace (s) passed through, that is, the length of the shoelace (s) remaining after passing through all the shoelace holes. It can be connected to (1, 5, etc.), and the shoelace (s) remaining after being inserted into the insertion hole (1, 5, etc.) is finally inserted between the shoe insole 1300 as shown in FIG. 11.

8 is a view showing various forms of the pillar part 20. These various types of pillars are intended to improve the fixing power or support of the shoelaces (s), and Fig. 8 (a) shows that the diameter of the through hole 22 of the column is reduced in one direction as in Fig. 13 (a). It is formed like a cone or a truncated cone, so that the shoelace inserted into the through hole is naturally fixed in the through hole of narrow diameter and movement is restricted.

Figure 8 (b) is formed in a dumbbell shape, as shown in Figure 13 (b), the disk-shaped plate 10 in the hole connected to the through hole 22 into which the column portion 20 is inserted into the disk-shaped plate 10 Covers of different sizes are formed on the upper and lower portions of the pillars so that they can be connected in a snap manner at the front and rear of the column. The upper cover (m) of a relatively small size is pushed into the hole of the upper disk-shaped plate (10), and the lower cover (n) of a relatively large size is sufficiently larger than the hole of the disk-shaped plate (10). The column part is fixed to the disc-shaped plate because it cannot pass through the hole.

8(c) shows that several layers of shades (z) are formed along the axis of the pillar portion, and the shade (z) has a slightly larger width or diameter than the hole into which the pillar portion 20 of the disk-shaped plate 10 is inserted. Is formed. Therefore, as shown in (c) of FIG. 13, friction between the shade of the pillar portion inserted into the hole of the disk-shaped plate 10 and the inner surface of the hole and the shade is formed larger than the diameter of the hole, so that the pillar portion It can be firmly fixed in the hole of the disc-shaped plate.

The shade (z) has a shape like a truncated cone arranged around the through hole 22 on the surface of the body 21 of the column part 20, and such a plurality of truncated cones are arranged to overlap vertically.

Figure 8 (d) and (e) is a form in which several wing portions (w1, w2) are formed around the length of the pillar portion, and the pillar portion is formed by friction between the wing portions (w1, w2) and the hole of the disk-shaped plate. The part can be fixed. The width of the wing portion w1 is changed, and the wing portion w2 has a constant width.

In (f) and (g) of FIG. 8, a plurality of protrusions are formed around the length of the pillar, so that the pillar may be fixed by friction between the protrusion and the hole of the disk-shaped plate. The protrusion (x) protrudes from the body 21 of the column in a spot form, and the protrusion y protrudes while rotating along the circumference of the body 21 of the column part.

8(h) and (i) are examples in which the column part 20 is manufactured in the form of a rectangular parallelepiped or polygonal column instead of a cylindrical shape, and is useful when the shoelace hole has a shape corresponding thereto.
