However, when the toe cap assembly of Patent Document 1 is provided on a shoe, even if the protective cap is made of a hard material and the shoe size is adjusted with shoelaces, the size of the front portion of the shoe cannot be reduced. Accordingly, the position of the foot cannot be properly fixed, and for this reason, the foot can be easily pushed into the inside of the protective cap, that is, in the forward direction of the shoe, when the user is walking or working while wearing the shoe.

As described above, when the user's foot is pushed in the forward direction of the shoe, the space between the protective cap and the foot is not sufficiently formed inside the protective cap. Therefore, when an external shock is applied to the protective cap due to falling objects and the protective cap is crushed, there is a problem in that the external shock may be applied to the foot as it is, resulting in injury to the foot.

In addition, even if the inner surface of the protective cap is provided with an endothelium, if the foot is pushed forward and reaches the front of the protective cap, it is not only uncomfortable to wear, but the protective cap itself is made of a hard material, causing injury to the foot. have.

The second foremost point A2 may be located at a position corresponding to the second MP joint point E. In other words, the second foremost point A2 may also be located in a range of 42 mm to 55 mm in the direction of the first baby toe side wall 400 from the first thumb toe side wall 300.

As above, as the second most anterior point (A2) is located at the position corresponding to the second MP joint point (E), the second MP joint point (E), the first most anterior point (A1), and the second most anterior point (A2) The second vertical plane P2 may be placed on the same line, and the second MP joint point E, the first most anterior point A1, and the second most anterior point A2 placed on the same line may pass.

In other words, the second vertical plane P2 becomes a vertical plane connecting all of the second MP joint point E, the first foremost point A1, and the second foremost point A2, and this second vertical plane P2 ) May be perpendicular to the first vertical plane P1.

The horizontal distance (d1) between the second MP joint point (E) and the first vertical plane (P1) is preferably 4 mm to 30 mm, and between the first vertical plane (P1) and the first most anterior point (A1). It is preferable that the horizontal distance d2 is 4 mm to 20 mm.

As above, as the relationship of the horizontal distance between the second MP joint point (E), the first vertical plane (P1), and the first foremost point (A1) is satisfied, the optimum curvature of the first curved portion 210 is set. I can.

In detail, the MP line MP becomes a reference line when the foot F is bent forward. Among these MP lines (MP), the second MP joint point (E) is located in the foremost position of the MP line (MP).

In the case of the toe cap 10 of the present invention, by setting the horizontal distance (d1) between the second MP joint point (E) and the first vertical plane (P1) to 4 mm to 30 mm, the user can see Figure 5 (b) As shown in, when the foot (F) is bent forward, the back of the foot can be prevented from contacting the toe cap 10, thereby making the user's shoe 1 more comfortable to wear, and to the folding of the foot. It is possible to prevent injuries to the back of the foot.

In addition, the horizontal distance d2 between the first vertical plane P1 and the first foremost point A1 is a value related to the curvature of the first curved portion 210. As described above, when the left and right widths of the toe cap 10, that is, the length w1 between the first rearmost point C1 and the second rearmost point C2, is 82 mm to 92 mm, the first 1 When the horizontal distance d2 between the vertical plane P1 and the first foremost point A1 is 4 mm to 20 mm, the first curved portion 210 has a smaller radius of curvature than the MP line MP. It can have a gentle curvature.

In other words, the horizontal distance (d2) between the first vertical plane (P1) and the first most front point (A1), and the length (w1) between the first rearmost point (C1) and the second most rear point (C2). In other words, when'd2:w1' satisfies the relationship of '1:4.1 to 23', the first curved portion 210 may have a smoother curvature than the MP line MP.

Accordingly, when the user bends the foot F forward, as shown in FIG. 10(b), even if the foot F is pushed in the forward direction and the instep touches the toe cap 10, the curvature of the instep Since the curvature of the first curved portion 210 is formed more gently, contact with the back of the foot can be prevented.

This effect may be more pronounced as the first foremost point A1 is at a position corresponding to the second MP joint point E. That is, although the shape of the curvature of the first curved portion 210 has a gentler curvature than the MP line MP, the position corresponding to the second MP joint point E is positioned in the foremost position, so that the first curved portion 210 This is because the shape of) itself is similar to the shape of the instep and has a smooth curved surface, through which it is possible to prevent contact with the instep.

In order to increase the effect of the first curved portion 210 as described above, the toe cap 10 preferably satisfies the following conditions.

A third vertical plane P3 connecting the first end point B1 of the first curved portion 210 to the second end point B2 of the first curved portion 210, and the first curved portion 210 The horizontal distance (d4) between the first foremost point (A1) of) is preferably 2mm to 8mm. In addition, the horizontal distance d5 between the third vertical plane P3 and the first vertical plane P1 is preferably 2 mm to 12 mm.

Therefore, the relationship of'horizontal distance (d2) = horizontal distance (d4) + horizontal distance (d5)' is satisfied. In addition, it is preferable that the ratio of the horizontal distance d4 and the horizontal distance d5, that is, the'horizontal distance d4: the horizontal distance d5', satisfies the '1: 0.25 to 6'relationship.

The toe cap 10 of the present invention preferably has a horizontal distance (d3) between the first foremost point (A1) and the second foremost point (A2) located in the foremost position of the toe cap (10) of 30 mm to 52 mm Do.

As above, as the horizontal distance d3 satisfies 30 mm to 52 mm, the streamlined shape in the front direction from both sides of the tow cap 10 may be formed to be more inclined. Accordingly, when the user moves, it is possible to effectively prevent the foot F from further entering the toe cap 10 in the forward direction.

In detail, as shown in FIG. 5(b), when the foot F is folded forward, the foot F may be pushed into the toe cap 10, that is, in the forward direction. However, as described above, when the streamlined shape in the forward direction from both sides of the toe cap 10 is formed to be more inclined, the outer surfaces of the big toe and the little toe are caught on both inner sides of the toe cap 10, and the foot F ) Is to be able to effectively prevent it from entering the inside of the toe cap (10).

Therefore, the above-described horizontal distance (d3) is organically combined with the configuration of the first curved portion 210 and the horizontal distance (d1), as shown in Figure 10 (b), the foot (F) is folded forward. When, it is possible to effectively prevent the instep from touching the toe cap (10).

In addition, due to the first curved portion 210, it is possible to compensate for the decrease in the horizontal distance of the upper surface of the toe cap 10 as the horizontal distance d3, so that the foot F caused by the falling object through the toe cap 10 There is an effect that can effectively prevent injuries.

Hereinafter, a difference between the conventional toe caps and the toe cap 10 according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 6 and 7.

Figure 8 (a) is a diagram showing the relationship between the conventional toe cap and the foot (F) mentioned in the prior art of Korean Patent Registration No. 10-1292383, Figure 8 (b) is Korean Patent Registration No. 10-1292383 It is a diagram showing the relationship between the toe cap of the arc and the foot (F), and Figure 8 (c) is the toe cap 10 and the foot (F) of the toe cap assembly (TA) according to the first embodiment of the present invention It is a diagram showing the relationship with.

In the following, for ease of explanation, the tow cap of FIG. 8 (a) is referred to as the first conventional toe cap 20, the toe cap of FIG. 8 (b) is referred to as the second conventional toe cap 30, and FIG. (c) The toe cap 10 of the toe cap assembly TA according to the first embodiment of the present invention is referred to as the toe cap 10 of the present invention.

The rearmost portion of the second conventional toe cap 30 extends rearward by a horizontal distance d6 than the rearmost portion of the first conventional toe cap 20.

The frontmost point of the first conventional toe cap 20 and the frontmost point of the second conventional toe cap 30 are located on the same line.

The extension side wall 31 of the second conventional toe cap 30 is formed to extend rearward by a horizontal distance d7 than the rearmost portion of the second conventional toe cap 30.

The rearmost portion of the toe cap 10 of the present invention, that is, the first vertical plane P1 connecting the first rearmost point C1 and the second rearmost point C2 of FIG. 7, is a first conventional toe cap ( It is extended by a horizontal distance (d7) rearward rather than the rearmost part of 20), and the foremost part of the toe cap 10 of the present invention, that is, the second foremost point A2 of FIG. 7, is the first conventional toe cap ( It extends forward by a horizontal distance d8 from the foremost part of 20) and the foremost part of the second conventional toe cap 30.

In addition, a first curved portion 210 is formed in the tow cap 10 of the present invention. Accordingly, the first curved portion 210 of the toe cap 10 of the present invention is spaced from the curved portion of the second conventional toe cap 30 forward by a horizontal distance d9.

In this case, it is preferable that the horizontal distance d9 has the same distance as the horizontal distance d2 of FIG. 7. This is, due to the first curved portion 210, as a horizontal distance d9 as much as the distance lost from the rear of the toe cap 10, by compensating the front of the toe cap 10, the strength of the toe cap 10 It is to maintain.

As described above, due to the difference between the toe cap 10 of the present invention and the first and second conventional toe caps 20 and 30, the toe cap 10 of the present invention has the following advantages.

Since the first curved portion 210 of the toe cap 10 of the present invention is spaced apart by a horizontal distance d9 in the forward direction than the second conventional toe cap 30, when the foot F is folded forward, the instep Contact with the toe cap 10 can be prevented more effectively than the second conventional toe cap 30.

Further, the first curved portion 210 of the tow cap 10 of the present invention is not formed by simply further extending the first curved portion 210 forward, but the first curved portion 210 is an MP line (MP ), while having a gentler curvature, the first foremost point (A1) is positioned to correspond to the second MP joint point (E), thereby preventing the instep from touching the toe cap (10) ergonomically and at the same time Make it more foldable.

Since the first foremost point (A1) of the toe cap 10 of the present invention is separated by a horizontal distance (d8) in the front direction than the first and second conventional toe caps 20 and 30, both sides of the toe cap 10 It has a streamlined shape that is more inclined forward than the first and second conventional tow caps 20 and 30. Therefore, when the foot (F) is bent forward, it is possible to prevent the foot (F) from being pushed in the forward direction, that is, the inner direction of the toe cap 10, and through this, the foot (F) can be bent forward. When, it is possible to effectively prevent the toe cap 10 from touching the instep.

Furthermore, by compensating the distance reduced by the first curved portion 210 forward, a safety distance for protecting the toes from falling objects can be secured. In detail, as described above, a distance d9 in front of the tow cap 10 by a distance reduced from the rear of the tow cap 10 due to the first curved portion 210, that is, a horizontal distance d2 ) By extending the toe cap 10 to form the front side of the toe cap 10, reducing the strength caused by the shortening of the toe cap 10, or insufficient separation distance between the toe and the front of the toe cap 10. It can be effectively prevented.

The second conventional toe cap 30 has an extended side wall 31 extending rearward from the rear end edge of the side wall of the first conventional toe cap 20 in the configuration of the first conventional toe cap 20 for protection of the little toe. to be.

This second conventional toe cap 30 is useful for protecting the little toe through the configuration of the extension side wall 31, but a curved edge formed to form an arc toward the inside at the rear end of the extension side wall 31 is additionally formed. Accordingly, when the instep is bent, the instep has a problem in that it contacts the curved edge more easily than the first conventional toe cap 20.

On the other hand, when the toe cap 10 of the present invention is bent on the basis of the first conventional toe cap 20, the instep is more in contact with the toe cap than the first conventional toe cap 20, thereby bending It was solved by the inconvenience caused by.

In other words, the second conventional toe cap 30 is intended to protect the little toe by adding an extended side wall 31 and a curved edge based on the first conventional toe cap 20, whereas the toe cap of the present invention (10) is to eliminate the discomfort caused by bending the instep by removing the portion that can be in contact with the instep through the first curved portion 210 based on the first conventional toe cap 20.

That is, the toe cap 10 of the present invention is a non-contact type toe cap 10 in which the instep does not contact the first curved portion 210 of the toe cap 10 when the foot F is bent forward. When the toe caps are used, the user's instep is in contact with the rear ends of the conventional toe caps, eliminating the feeling of discomfort.

As described above, the toe cap 10 of the present invention has a structural difference from the first conventional toe cap 20 and the second conventional toe cap 30, through which, when the foot F is folded forward Unlike the first conventional toe cap 20 and the second conventional toe cap 30, it is possible to effectively prevent the instep from touching the toe cap 10.

Hereinafter, the soft member 700 will be described.

1, 2, 9 to 11, the soft member 700 is coupled to the rear of the tow cap 10, the body having an arcuate curved shape like the rear of the tow cap 10 ( 710, and the outer surface of the body 710 is formed to be stepped in the front direction of the body 710 to have an outer surface lower than the outer surface, the outer surface of which is the first upper wall 200, the first thumb toe side wall 300 ) And the first baby toe side wall 400, which is provided on the inner surfaces of both sides of the bonding blades 730 in contact with each of the inner surfaces, and the bonding blades 730, respectively, and the thickness of which is formed thicker toward the front direction. , It may be configured to include two cushion units (750, 770).

The soft member 700 may be made of a soft material having a hardness lower than that of the material of the tow cap 10. The soft material may be rubber, synthetic rubber, or soft plastic. For example, when the tow cap 10 is made of a metal or hard plastic material, the soft member 700 may be made of a rubber, synthetic rubber, or a soft plastic material having a lower hardness than the material of the toe cap 10.

In the body 710, a second upper wall 711, a second thumb toe side wall 712, and a second baby toe side wall 713 form an upper surface and both side surfaces of the body 710, respectively. Therefore, the outer surface of the body 710 is the outer surface of the second upper wall 711, the second thumb toe side wall 712 and the second baby toe side wall 713, the inner side of the body 710 is a second It is an inner surface of the upper wall 711, the second thumb toe side wall 712, and the second baby toe side wall 713.

The second upper wall 711, the second thumb toe side wall 712, and the second baby toe side wall 713 have the same arcuate curved shape as the rear of the toe cap 10.

The bonding blades 730 are formed stepped in the front direction of the body 710 so as to have an outer surface lower than the outer surface of the body 710.

In the bonding wing 730, the third upper wall 731, the third thumb toe side wall 732, and the third baby toe side wall 733 form the upper and both sides of the bonding wing 730, respectively. Therefore, the outer surface of the bonding wing 730 is the outer surface of the third upper wall 731, the third thumb toe side wall 732 and the third baby toe side wall 733, the inner side of the bonding wing 730 It is an inner side surface of the third upper wall 731, the third thumb toe side wall 732, and the third baby toe side wall 733. Bonding wing 730 also, like the body 710, has an arcuate curved shape such as the rear of the tow cap 10.

As above, by forming a step in the front direction of the body 710 so that the outer surface of the bonding blade 730 has a lower outer surface than the outer surface of the body 710, the soft member 700 is the tow cap 10 When coupled to the rear of the joint blade 730, the outer surface of the first upper wall 200, the first thumb toe side wall 300, and the first baby toe side wall 400, each of the inner side of the contact, this Through this, the soft member 700 can be easily coupled to the rear of the tow cap 10.

In other words, through the stepped structure of the soft member 700, when the tow cap 10 and the soft member 700 are combined to form a tow cap assembly TA, FIGS. 1, 2, 9, and 11 As shown in, the outer surface of each of the third upper wall 731, the third thumb toe side wall 732, and the third baby toe side wall 733 of the bonding wing 730 is the first of the toe cap 10 The upper wall 200, the first thumb toe side wall 300, and the first baby toe side wall 400 are in contact with each of the inner surfaces.

In addition, the outer surface of each of the second upper wall 711, the second thumb toe side wall 712, and the second baby toe side wall 713 of the body 710 is the first upper wall 200 of the toe cap 10 , The first thumb toe side wall 300 and the first baby toe side wall 400 have the same height as the outer surface of each. That is, in the tow cap assembly TA, the outer surface of the tow cap 10 and the outer surface of the soft member 700 have the same height, so there is no step.

In other words, the outer surface of each of the second upper wall 711, the second thumb toe side wall 712, and the second baby toe side wall 713 of the body 710 is, the first upper wall of the toe cap 10 ( 200), the first thumb toe side wall 300 and the first baby toe side wall 400 have the same height without forming a step and the outer surface of each.

In addition, the outer surface of each of the third upper wall 731, the third thumb toe side wall 732, and the third baby toe side wall 733 of the bonding wing 730, that is, the outer surface of the bonding wing 730 is bonded. A material (e.g., an adhesive) may be applied, through which the third upper wall 731 of the bonding blade 730, the third thumb toe side wall 732, and the third baby toe side wall 733 are each The sides and inner surfaces of each of the first upper wall 200, the first thumb toe side wall 300, and the first baby toe side wall 400 of the toe cap 10 can be easily coupled.

A fourth curved portion 714 fitted to the first curved portion 210 may be provided at a front end of the second upper wall 711 of the body 710.

The fourth curved portion 714 is formed with the same curvature as the first curved portion 210 of the toe cap 10 described above. Accordingly, when the tow cap 10 and the soft member 700 are coupled, the fourth curved portion 714 is fitted into the first curved portion 210. In this case, the first curved portion 210 is a concave curved surface from which the rear of the tow cap 10 is removed, that is, a negative (-) curved surface, and the fourth curved portion 714 is the body of the soft member 700 ( The second upper wall 711 of the 710 is a convex curved surface protruding forward, that is, a positive (+) curved surface. Accordingly, when the tow cap 10 and the soft member 700 are coupled, the fourth curved portion 714 can be easily fitted to the rear of the first curved portion 210.

In addition, as above, when the fourth curved portion 714 is formed, the third upper wall 731 of the bonding wing 730 may be formed to protrude forward by the length of the fourth curved portion 714 is formed. Furthermore, a curved portion having the same shape as the fourth curved portion 714 may be formed. This is due to the fourth curved portion 714, there is not enough space to apply a bonding material or the like on the outer surface of the third upper wall 731, the outer surface of the third upper wall 731 and the first upper wall ( This is to prevent the inner side of 200) from being properly bonded.

The first cushion unit 750 may be provided on an inner surface of one side of the bonding blade 730 (in the present invention, the left direction or the big toe side direction in FIG. 11 ). In detail, the first cushion unit 750 may be provided on the inner side of the third thumb toe side wall 732 of the bonding wing 730.

In this case, the first and second cushion portions 750 and 770 may be made of a soft material having a hardness lower than that of the material of the tow cap 10. Further, it is preferable that the hardness of the soft material constituting the first and second cushion portions 750 and 770 has a hardness of 10 or less Shore-A. Such a material having a hardness of Shore-A less than 10 has soft and soft properties.

In other words, each of the first and second cushion portions 750 and 770 is integrally formed and provided on the inner surfaces of the third thumb toe side wall 732 and the third baby toe side wall 733 of the bonding wing 730, or , It may be provided by combining (or bonding) separately.

Hereinafter, a state of use of the tow cap assembly TA according to the first preferred embodiment of the present invention having the above-described configuration will be described with reference to FIG. 10.

Figure 10 (a) is a diagram showing a state when the foot is worn on a shoe equipped with a toe cap assembly, and Figure 10 (b) is a state when the foot is bent forward in the state of Figure 10 (a) It is an illustrated diagram.

As described above, the toe cap assembly (TA) is provided in the inside of the front nose of the shoe (1), it functions to protect the foot (F).

An insole (insole, 2) is provided on the upper portion of the bent portion 500 of the toe cap 10, and the insole 2 is a part where the sole of the foot touches.

A midsole (3) is provided under the insole (2), and an outsole (4) forming the bottom of the shoe (1) is provided under the midsole (3).

In addition, the outer surface of the toe cap assembly (TA) is wrapped with a shell (5), this shell (5) forms the outer surface and shape of the shoe (1).

When the user wears the shoe 1 having the toe cap assembly TA having the above configuration, the toe cap assembly TA is positioned at the front of the foot F, as shown in FIG. 10(a). In this case, the toe cap 10 covers the front, both sides, and the upper part of the front part of the foot F, and thereby protects the front part of the foot, that is, toes, from falling objects. The soft member 700 covers both sides and both sides of the foot F at the rear of the toe cap 10, and prevents the hard part of the toe cap 10 from touching the foot F, thereby increasing the fit. This is, even if the endothelium is provided on the inner side of the toe cap assembly (TA), when the foot (F) touches the place where the toe cap 10 is located, the toe cap 10 itself has a high hardness, so you can feel pain Because there is.

The tow cap assembly TA according to the first embodiment of the present invention having the above-described configuration has the following effects.

Since the first and second cushion portions 750 and 770 are provided in the soft member 700, as shown in FIG. 11, the big toe of the foot F is fixed by the first cushion portion 750, and The toe is fixed by the second cushion unit 770, through which the foot (F) is moved to the inside of the toe cap assembly (TA), that is, in the forward direction of the shoe (1) when the user is walking or working while wearing the shoe. It can effectively prevent it from being pushed in. Therefore, unlike the conventional tow cap assembly, it is possible to sufficiently secure a space between the first front wall 100 of the toe cap 10 of the toe cap assembly TA and the front portion of the foot F. Through this, even if an external impact is applied to the toe cap 10 due to a falling object and the toe cap 10 is crushed, the external impact can be prevented from being directly applied to the foot.

In addition, since a sufficient space is secured between the first front wall 100 of the toe cap 10 of the toe cap assembly TA and the front portion of the foot F, the foot F is pushed forward, making it hard It is possible to increase the fit of the shoe 1 by preventing it from touching the first front wall 100 of the toe cap 10.

Since the first curved portion 210 is provided in the toe cap 10, when the foot is folded forward, the instep does not touch the rear of the toe cap 10, and at the same time, the soft soft member 700 is attached to the instep. By touching it, a high fit can be achieved. In detail, when the user performs work, walking, etc., when the foot (F) is bent forward as shown in FIG. 10(b), the user's foot (F) is forward along the MP line (MP) of FIG. , That is, it is bent forward. In this case, due to the first curved portion 210 provided in the toe cap 10, a separation space occurs between the instep of the foot F folded forward and the first curved portion 210, and such a separation space In the soft member 700 is located. Accordingly, it is possible to prevent the user's instep from directly contacting the toe cap 10, and thus, it is possible to prevent the occurrence of pain in the instep.

A soft member 700 that is relatively softer than the tow cap 10 because the toe cap 10 is configured so that the first vertical plane P1 which is the YZ plane and the second vertical plane P2 which is the XZ plane are perpendicular to each other. There is an effect that the bending line of is perpendicular to the second vertical plane P2 which is the XZ plane. In detail, since the first foremost point A1 and the second MP joint point E of the toe cap 10 are located on the second vertical plane P2, which is the XZ plane, it is shown in FIG. 10(b). As described above, when the instep is folded by bending the foot forward, the soft member 700 is folded along the bending line connecting the first and second rearmost points C1 and C2 located on the first vertical plane P1. Is induced. Therefore, the second MP joint point E is folded along the second vertical plane P2, and through this, it is possible to prevent the instep from contacting the rear of the toe cap 10 as much as possible.

In addition, as shown in Figure 10, when the toe cap assembly (TA) is provided in the shoe (1), the outer skin (5), also, the first and second most rear points located on the first vertical plane (P1) ( It is folded along the bending line connecting C1 and C2, and thus, when the user folds the foot F forward, the foot F can be folded forward without discomfort. In other words, when walking or working, the user's fit may be increased.

A third cushion part (not shown) may be provided on the inner side of the third upper wall 731 of the bonding blade 730 of the above-described soft member 700.

The third cushion portion may be provided on an inner surface of a region of the bonding blade 730 in which the first and second cushion portions 750 and 770 are not formed. Specifically, the first cushion portion 750 is provided on the inner surface of the third thumb toe side wall 732 of the bonding wing 730, and the second cushion portion 770 is the third child of the bonding wing 730 When provided on the inner side of the toe side wall 733, the third cushion portion may be provided on the inner side of the third upper wall 731 of the bonding blade 730.

The third cushion portion is formed to become thicker toward the front.

In this case, the third cushion part does not contact the upper part of the foot (F), but when the foot (F) is pushed in the forward direction of the shoe 1, that is, in the inner direction of the toe cap assembly (TA), By contacting, it functions to prevent the foot F from being pushed in the forward direction of the shoe 1, that is, the inner direction of the toe cap assembly TA over a predetermined distance.

The above-described third cushion may be formed by being coupled to the inner side of the third upper wall 731 of the bonding blade 730 as a separate component. In this case, the third cushion portion may be made of a soft material having a hardness lower than that of the material of the tow cap 10. Further, it is preferable that the hardness of the soft material constituting the third cushion part has a hardness of 10 or less Shore-A. Such a material having a hardness of Shore-A less than 10 has soft and soft properties.

Also, the third cushion unit may be integrally formed with the first cushion unit 750 and the second cushion unit 770.
