Description

Technical Field

[0001] The present invention relates to a safety shoe for a wearer's foot. Background Art

[0002] Safety shoes used in industrial sites are of various types depending on their uses.

[0003] Generally speaking, safety shoes refer to shoes used to protect feet from falling objects in factories or construction sites, or to protect feet from being hit by very sharp or hard objects while walking.

[0004] In particular, safety shoes used at construction sites must have a very thick outer layer in order to prevent heavy objects from falling and injuring the feet or to absorb the impact of falling objects. The thickness is determined by industrial safety regulations.

[0005] In addition, in order to protect the feet from being injured by sharp or pointed objects falling on the ground, the thickness of the bottom material such as the outsole and the midsole should also be thick.

[0006] Therefore, in order to safely protect the feet, the overall structure of safety shoes is made of a hard outer leather, and the thickness of the bottom material must also be considered. At the same time, for mobility, it should be made of a soft and highly compressible material.

[0007] As described above, the thickness of the safety shoes must be much thicker, and therefore, the wearing feeling of the wearer is much lower than that of general shoes.

[0008] Particularly, the wearer may feel stuffy due to the hard outer cover of the safety shoe, and therefore, there arises a problem point that the wearer feels discomfort in the foot and further feels pain in the foot when the wearer wears the safety shoe for a long time.

[0060] Safety shoes (10) according to a first embodiment of the present invention

[0061] The following reference Figures 1 to 7b , a safety shoe (10) according to a first embodiment of the present invention is described.

[0062] Figure 1 is a side view of a safety shoe according to a first embodiment of the present invention, Figure 2 is a perspective view of an enlarged front nose portion of a safety shoe according to a first embodiment of the present invention, Figure 3 is a perspective view showing a state in which the outer cover is removed in the safety shoe according to the first embodiment of the present invention, Figure 4 is a perspective view showing the position of a protruding member in a safety shoe according to a first embodiment of the present invention, Figure 5a and Figure 5b is a perspective view of the toe of a safety shoe according to a first embodiment of the present invention, Figure 6 is a diagram showing a state in which a wearer's foot is worn in the safety shoe according to the first embodiment of the present invention, and Figure 7a and Figure 7b FIG. 1 is a perspective view of a protruding component of a safety shoe according to a first embodiment of the present invention.

[0063] like Figures 1 to 7bAs shown in the figure, the safety shoe (10) according to the first embodiment of the present invention is a safety shoe (10) for a wearer's foot (F), and comprises the following components: an insole (110) for placing the wearer's foot (F); a midsole (120) arranged at the lower part of the insole (110); a sole (130) arranged at the lower part of the insole (110) and the midsole (120) and constituting the bottom of the safety shoe (10); an outer skin (140) arranged at the upper part of the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F) and constituting the shape of the safety shoe (10); a toe cap (200) included in the foot (F); The safety shoe (10) comprises a recessed portion (260) formed in a forward direction at the position of the little toe (LT); a protruding component (400) arranged on the inner side of the outer skin (140) in a manner corresponding to the little toe (LT) of the foot (F), and protruding outwardly to form an inner space (411) on the inner side for the little toe (LT) to move; and a combining component (300) arranged inside the front nose of the safety shoe (10) and including a protruding portion (310) having a shape corresponding to the recessed portion (260) and embedded in the recessed portion (260), and arranged behind the toe cap (200) and combined with the toe cap (200).

[0064] The insole (110) is a part for the wearer's foot (F) to be placed and contact the sole of the foot, and is located on the upper part of the midsole (120).

[0065] In addition, the insole (110) is located above the bent portion (250) of the toe (200).

[0066] A midsole (120) and a sole (130) are provided at the lower part of the insole (110).

[0067] A sole (130) constituting the bottom of the safety shoe (10) is provided at the lower part of the midsole (120).

[0068] An outer skin (140) is provided on the upper part of the midsole (120) and the sole (130) to surround the foot (F) of the wearer.

[0069] The outer skin (140) surrounds the outer surface of the wearer's foot (F) and the toe (200), and forms the outer surface and shape of the safety shoe (10).

[0070] In order to protect the wearer's foot (F) from falling objects and sharp objects, the outer skin (140) can be formed of a hard material.

[0071] As described above, the safety shoe (10) has a midsole (120) and a sole (130) disposed below the midsole (120), so that the sole (130) can have a multi-layered outer sole structure constituting the bottom of the safety shoe (10).

[0072] Different from this, the safety shoe (10) may also include only the midsole (120) or the sole (130), so that the midsole (120) or the sole (130) has a multi-layer outer sole structure constituting the bottom of the safety shoe (10).

[0073] like Figures 3 to 5b As shown, the toe box (200) may include the following: a front wall (210), which is arranged inside the front nose of the safety shoe (10) and constitutes the front side of the toe box (200); an upper wall (220), which constitutes the upper surface of the toe box (200); a big toe side wall (230), which constitutes the big toe side surface of the toe box (200); a little toe side wall (240), which constitutes the little toe side surface of the toe box (200); a bending portion (250), which is formed by bending and extending at the lower part of the front wall (210), the big toe side wall (230) and the little toe side wall (240), and is formed in a manner that constitutes a part of the bottom surface of the toe box (200); and a recessed portion (260), which is formed at the rear end of the little toe side wall (240) in a recessed manner toward the front direction of the toe box (200) and leaves at least a part of the rear end of the little toe side wall (400) open.

[0074] For the toe box (200), the front wall (210), the upper wall (220), the big toe side wall (230), and the little toe side wall (240) respectively constitute the front surface, the upper surface and the two side surfaces of the toe box (200), and the bending portion (250) formed by bending and extending at the lower part of the front wall (210), the big toe side wall (230) and the little toe side wall (240) is formed in a manner that constitutes a part of the bottom surface of the toe box, and the rear end of the little toe side wall (240) may have a recessed portion (260), and the recessed portion (260) is formed from the rear end of the little toe side wall (240) toward the front direction of the toe box (200) and makes at least a part of the rear end of the little toe side wall (240) open.

[0075] With the above-mentioned structure, a part of the bottom surface of the toe cap (200) is open, and the front surface, the upper surface and the two side surfaces have a closed shape by the front wall (210), the upper wall (220), the big toe side wall (230) and the little toe side wall (240). However, in this case, since a part of the little toe side wall (240) is open due to the recessed part (260), the area on the side of the little toe side wall (240) where the recessed part (260) is formed is not closed but open.

[0076] The front wall (210), the upper wall (220), the big toe side wall (230) and the little toe side wall (240) are formed as a whole in a manner of extending each other, and the front wall (210), the upper wall (220), the big toe side wall (230) and the little toe side wall (240) are each processed into a curved surface, so that the overall shape is streamlined in a form that becomes narrower toward the front of the toe (200).

[0077] The bent portion (250) is formed in a manner of bending and extending at the lower portions of the front wall (210), the big toe side wall (230) and the little toe side wall (240).

[0078] The bent portion (250) only constitutes a portion of the bottom surface of the toe cap (200). Figure 5a and Figure 5b As shown, the bent portion (250) has a "U" shape as a whole. Therefore, the bottom surface of the toe cap (200) has a "U" shape with an open interior.

[0079] The bending portion (250) is bent toward the bottom surface of the toe cap (200) so that the angle formed by the inner surface of each of the front wall (210), the big toe side wall (230) and the little toe side wall (240) and the upper surface of the bending portion (250) is greater than 90 degrees. In this case, the width of the bending portion (250) is several millimeters (mm) to several tens of millimeters.

[0080] The toe cap (200) is formed of a hard material such as metal, and thus can protect the foot (F) from being hurt by falling objects.

[0081] In the case of a safety shoe (10) having a toe cap (200), an insole (110) is positioned above the bent portion (250).

[0082] The front wall (210) constitutes the front side of the toe cap (200) and has a shape in which the width becomes narrower toward the front. In this case, the front wall (210) has a curve with curvature, and thus the front wall (210) has a streamline shape.

[0083] The upper wall (220) extends from the central rear end of the front wall (210) and forms the upper surface of the toe cap (200).

[0084] The upper wall (220) covers the upper part of the wearer's toes, thereby protecting the wearer's toes from being injured by falling objects.

[0085] The big toe side wall (230) extends from the big toe side rear end of the front wall (210) and forms the side surface of the toe cap (200). Figures 1 to 5bAs shown, when the safety shoe (10) is a safety shoe (10) for the right foot, the big toe side wall (230) of the toe cap (200) constitutes the left side surface of the toe cap (200).

[0086] The big toe side wall (230) has a shape that is inclined toward the big toe side as it goes backward. In this case, the big toe side wall (230) has a curve with curvature and thus has a streamlined shape.

[0087] The little toe side wall (240) extends from the little toe side rear end of the front wall (210) and constitutes the side surface of the toe cap (200). In the case where the safety shoe (10) is a safety shoe (10) for the right foot, the little toe side wall (240) of the toe cap (200) constitutes the right side surface of the toe cap (200).

[0088] A recessed portion (260) is provided on the side wall (340) of the little toe.

[0089] The recessed portion (260) is formed recessed from the rear end of the little toe side wall (240) toward the front direction of the toe cap (200). Therefore, the recessed portion (260) opens at least a portion of the rear end of the little toe side wall (240).

[0090] like Figure 6 As shown, when the wearer wears the safety shoe (10), the recessed portion (260) plays a role in preventing the little toe (LT) from contacting the little toe side wall (240) of the toe cap (200).

[0091] In other words, when a wearer wears the safety shoe (10) having the toe cap (200), a recessed portion (260) is formed at a position corresponding to where the little toe (LT) is located, and thus, the recessed portion (260) functions to prevent the little toe (LT) from contacting the little toe side wall (240) of the toe cap (200).

[0092] The recessed portion (260) is formed at the upper portion of the bent portion (250).

[0093] The recessed portion (260) is formed at a position spaced apart from the bent portion (250) toward the upper portion, and thus, a spaced portion (241) is formed between the recessed portion (260) and the bent portion (250).

[0094] The partition portion (241) means a portion of the little toe side wall (240) connecting the bent portion (250) and the recessed portion (260) at the lower portion of the recessed portion (260).

[0095] In other words, the recessed portion (260) is formed at a position separated from the upper portion of the bent portion (250), thereby forming a partition (241) between the recessed portion (260) and the bent portion (250), and the partition (241) is a part of the little toe side wall (240) that connects the bent portion (250) and the recessed portion (260) at the lower part of the recessed portion (260).

[0096] As described above, since the partition portion (241) is formed between the recessed portion (260) and the bent portion (250), the curved shape of the recessed portion (260) can be easily formed.

[0097] In addition, since the partition portion (241) is formed, the function of the recessed portion (260) for relieving external impact applied to the toe cap (200) can be further maximized.

[0098] Due to the formation of the above-mentioned recessed portion (260), the big toe side wall (230) and the little toe side wall (240) of the toe cap (200) have different shapes from each other. In other words, the big toe side wall (230) and the little toe side wall (240) of the toe cap (200) have mutually asymmetrical shapes.

[0099] The protruding member (400) is arranged on the outside of the toe cap (200) and the inside of the outer skin (140) so as to be arranged at a position corresponding to the little toe (LT) of the foot (F). That is, the protruding member (400) is interposed between the toe cap (200) and the outer skin (140).

[0100] The protruding part (400) may include the following: a protruding portion (410) forming an internal space (411) on the inner side and being formed to bulge outward; an edge portion (420) arranged along the periphery of the protruding portion (410); and a connecting portion (430) formed by the area where the protruding portion (410) and the edge portion (420) are connected.

[0101] The protrusion (410) is formed to protrude outward with the edge (420) as a reference so as to form an internal space (411) inside.

[0102] Specifically, the protrusion (410) is formed at the position of the outer skin (140) corresponding to the little toe (LT) and protrudes outward with the edge (420) as a reference. In this case, the protrusion length of the protrusion (410) is preferably greater than 2 mm and less than 4 mm.

[0103] The protrusion (410) may have a pentagonal shape as a whole. In this case, the rear of the protrusion (410) is preferably formed to have the longest side among the five sides of the pentagon of the protrusion (410).

[0104] The edge portion (420) is arranged along the periphery of the protruding portion (410).

[0105] The edge portion (420) has a flat shape, and the protrusion (410) protrudes outward with respect to the edge portion (420).

[0106] The outer side surface of the edge portion (420) is located on the inner side than the outer side surface of the protruding portion (410).

[0107] An inner space (411) is formed inside the inner side of the protruding portion (410), and therefore, the inner side of the edge portion (420) is located inside compared to the inner side of the protruding portion (410).

[0108] The internal space (411) is a space from the inner side surface of the edge portion (420) to the inner side surface of the protruding portion (410).

[0109] The inner side of the edge portion (420) contacts the outer side of the toe cap (200), so that when the protrusion (410) of the protrusion member (400) is positioned corresponding to the recess (260) of the toe cap (200), the protrusion member (400) can be supported by the edge portion (420).

[0110] The connecting portion (430) is formed by a region where the protruding portion (410) and the edge portion (420) are connected.

[0111] In the case where the protrusion (410) has a pentagonal shape, the connection portion (430) may be formed with five faces in a manner corresponding to the pentagonal protrusion (410). Therefore, the connection portion (430) is entirely formed in a closed manner.

[0112] The boundary lines of the faces of the connecting portion (430) are connected to the vertices of the protruding portion (410). Therefore, when the protruding portion (410) has a pentagonal shape, five vertices and the boundary lines of five faces are connected to each other.

[0113] The protruding part (400) is located outside the recessed part (260) of the toe cap (200). Figure 6 As shown, the protrusion (410) of the protruding member (400) is located at a position corresponding to the recess (260) of the toe cap (200). Therefore, the recess (260) is located inside the inner space (411) of the protrusion (410).

[0114] The outer skin (140) also protrudes convexly toward the outside through the protruding part (400). Therefore, the overall appearance of the safety shoe (10) can show the shape of the protruding part (400).

[0115] The toe cap (200), the protruding member (400) and the outer skin (140) can be combined with each other and formed into one piece by heat pressing or the like. Therefore, the position of the protruding member (400) is fixed and the inner space (411) of the protruding portion (410) can be continuously located outside the recessed portion (260), thereby ensuring space for the movement of the little toe (LT).

[0116] The coupling component (300) is arranged behind the toe cap (200) and coupled to the toe cap (200) in the front-rear direction.

[0117] A protrusion (310) is arranged on one side of the coupling component (300).

[0118] The protrusion (310) has a shape corresponding to the depression (260).

[0119] The protrusion (310) is arranged on the side of the little toe in the coupling member (300) at a position corresponding to the recess (260).

[0120] When the protrusion (310) is embedded in the recess (260), the coupling component (300) is coupled to the toe cap (200) in the front-rear direction.

[0121] The connecting component (300) is formed of a soft material. Therefore, the connecting component (300) plays a role in preventing the wearer's instep from hitting the rear of the upper wall (220) of the toe cap (200) and causing pain.

[0122] When the convex part (310) is combined with the concave part (260) by using the combining member (300), the inner space (411) of the protruding part (410) is positioned outside the convex part (310).

[0123] The safety shoe (10) according to the first embodiment of the present invention has a recessed portion (260), a raised portion (310) and a protruding portion (410) positioned at a position corresponding to the little toe (LT).

[0124] The recessed portion (260), the raised portion (310) and the protruding portion (410) ensure a space for the little toe (LT) of the wearer to move, thereby preventing the wearer from feeling stuffy or causing pain by hitting the little toe (LT) on the inner side of the outer skin (140) or the little toe side wall (240) of the toe cap (200).

[0125] In detail, in the case of conventional safety shoes, there is a problem that the wearer's toes touch the inner side of the outer skin or the inner side of the toe due to the hard outer skin or the toe, which causes discomfort. In particular, in the case of safety shoes with a toe, in order to solve this problem, if the toe size is made larger, the size of the safety shoe will become larger and heavier according to the size of the toe, and the fitting feeling will be insufficient.

[0126] In order to solve the above-mentioned problem, in the case of the present invention, a protrusion (410) having an internal space (411) is separately arranged on the inner side of the safety shoe (10) to ensure space for the little toe (LT) to escape in the outward direction, thereby ensuring space even if the size of the safety shoe (10) or the toe (200) is not made large, and improving the wearing feeling while maintaining the fit of the safety shoe (10) .

[0127] In addition, since the connecting member (300) and the protrusion (310) are formed of a soft material, the freedom of the little toe (LT) is guaranteed even with the protrusion (310). That is, since the protrusion (310) is formed of a soft material, when the little toe (LT) moves outward, it moves outward from the protrusion (310) or the internal space (411), thereby ensuring the free movement of the little toe (LT).

[0128] As described above, since the free movement of the little toe (LT) is guaranteed, the wearer can feel a good wearing feeling even if the outer cover (140) of the safety shoe (10) is formed of a hard material.

[0129] The safety shoe (10) according to the first embodiment of the present invention can achieve the goal of ensuring space for the little toe (LT) by means of the protruding component (400) even in a structure without a toe cap (200).

[0130] Safety shoes (10a) according to a second embodiment of the present invention

[0131] The following reference Figure 8 , a safety shoe (10a) according to a second embodiment of the present invention is described.

[0132] Figure 8 1 is a perspective view showing a state in which the outer cover is removed in the safety shoe according to the second embodiment of the present invention.

[0133] like Figure 8As shown, the safety shoe (10a) according to the second embodiment of the present invention may include the following: an insole (110) for placing the wearer's foot (F); a midsole (120) arranged at the lower part of the insole (110); a sole (130) arranged at the lower part of the insole (110) and the midsole (120) and forming the bottom of the safety shoe (10a); an outer skin (140) arranged at the upper part of the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F) and forming the shape of the safety shoe (10a); a toe cap (200) including a concave portion (260) formed in a forward direction at the position of the little toe (LT) of the foot (F); 0); a protruding component (400) arranged on the inner side of the outer skin (140) in a manner corresponding to the little toe (LT) of the foot (F), and protruding outwardly to form an inner space (411) on the inner side for the little toe (LT) to move; a combining component (300) arranged inside the front nose of the safety shoe (10a) and including a protruding portion (310) having a shape corresponding to the recessed portion (260) and embedded in the recessed portion (260), and arranged behind the toe cap (200) and combined with the toe cap (200); and a soft component (470) arranged on the inner side of the protruding portion (410) of the protruding component (400).

[0134] The safety shoe (10a) according to the second embodiment of the present invention has the same structure as the safety shoe (10) according to the first embodiment of the present invention except that it additionally includes a soft component (470). Therefore, the description of the same structure can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and the repeated description is omitted.

[0135] The soft component (470) is arranged inside the protruding portion (410) of the protruding component (400).

[0136] Specifically, the soft member (470) may be disposed in the internal space (411) formed inside the protrusion (410). In this case, the soft member (470) may be disposed so as to fill at least a portion of the internal space (411).

[0137] The soft component (470) may be formed of a soft, flexible and elastic material, such as sponge, ethylene-vinyl acetate (EVA), etc.

[0138] The soft component (470) as described above is arranged inside the internal space (411) and prevents the little toe (LT) from directly touching the inner side of the protrusion (410), thereby playing a role in improving the wearing feeling.

[0139] That is, since the little toe (LT) directly touches the soft and fluffy soft component (470), the wearer can feel a higher wearing feeling compared to when the little toe (LT) directly touches the inner side of the protrusion (410) of the relatively hard protrusion component (400).

[0140] Such a soft component (470) can be arranged on the inner side of the protruding portion (410) of the protruding component (400) by bonding with an adhesive or the like.

[0141] The soft component (470) can also be applied to the inner space (411, 411b, 271c, 143e) of the safety shoe (10) according to the first embodiment of the present invention and the safety shoe (10b-10e) according to the third to sixth embodiments described below.

[0142] Safety shoes (10b) according to a third embodiment of the present invention

[0143] The following reference Figures 9 to 11b , a safety shoe (10b) according to a third embodiment of the present invention is described.

[0144] Fig. 9 FIG. 1 is an enlarged perspective view of the front nose portion of the safety shoe according to the third embodiment of the present invention. Fig.10 is a perspective view showing the position of a protruding member in a safety shoe according to a third embodiment of the present invention, and Fig.11a and Fig.11b FIG. 4 is a perspective view of a protruding component of a safety shoe according to a third embodiment of the present invention.

[0145] like Figures 9 to 11b As shown, the safety shoe (10b) according to the third embodiment of the present invention may include the following components: an insole (110) for placing the wearer's foot (F); a midsole (120) disposed at the lower part of the insole (110); a sole (130) disposed at the lower part of the insole (110) and the midsole (120) and forming the bottom of the safety shoe (10b); an outer skin (140) disposed at the upper part of the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F) and forming the shape of the safety shoe (10b); a toe cap (200) included at the position of the little toe (LT) of the foot (F); A recessed portion (260) formed in a concave manner in the forward direction; a protruding component (400b) arranged on the inner side of the outer skin (140) in a manner corresponding to the little toe (LT) of the foot (F), and protruding outwardly to form an inner space (411) on the inner side for the little toe (LT) to move; and a combining component (300) arranged inside the front nose of the safety shoe (10b) and including a protruding portion (310) having a shape corresponding to the recessed portion (260) and embedded in the recessed portion (260), and arranged behind the toe cap (200) and combined with the toe cap (200).

[0146] The safety shoe (10b) according to the third embodiment of the present invention differs from the safety shoe (10) according to the first embodiment of the present invention in that only the shape of the protruding part (400b) is different, and the remaining components are the same. Therefore, the description of the same components can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and the repeated description is omitted.

[0147] The protruding member (400b) is arranged on the outside of the toe cap (200) and the inside of the outer skin (140) in a manner that the protruding member (400b) is arranged at a position corresponding to the little toe (LT) of the foot (F). That is, the protruding member (400b) is interposed between the toe cap (200) and the outer skin (140).

[0148] The protruding part (400b) may include the following: a protruding portion (410b) having an internal space (411b) formed inside and formed to bulge outward; an edge portion (420b) arranged along the periphery of the protruding portion (410b); and a connecting portion (430b) formed by the area where the protruding portion (410b) and the edge portion (420b) are connected.

[0149] The protrusion (410b) is formed to protrude outward with the edge (420b) as a reference so as to form an internal space (411b) inside.

[0150] The protrusion (410b) is formed to protrude outwardly at the position of the outer skin (140) corresponding to the little toe (LT) with the edge (420b) as a reference. In this case, the protrusion length of the protrusion (410b) is preferably not less than 2 mm and not more than 4 mm.

[0151] The protrusion (410b) may have a pentagonal shape as a whole.

[0152] The edge portion (420b) is arranged along at least a portion of the periphery of the protruding portion (410b).

[0153] As an example, the edge portion (420b) is arranged along the front, upper, and lower portions of the protruding portion (410b) except the rear portion. In other words, the edge portion (420b) is arranged along the peripheral edge of the protruding portion (410b) except the rear portion.

[0154] The edge portion (420b) has a flat shape, and the protrusion (410b) protrudes outward with respect to the edge portion (420b).

[0155] The outer side surface of the edge portion (420b) is located on the inner side than the outer side surface of the protruding portion (410b).

[0156] An inner space (411b) is formed inside the inner side surface of the protruding portion (410b), and therefore, the inner side surface of the edge portion (420b) is located inside compared to the inner side surface of the protruding portion (410b).

[0157] The internal space (411b) is a space extending from the inner side surface of the edge portion (420b) to the inner side surface of the protruding portion (410b).

[0158] The inner side of the edge portion (420b) contacts the outer side of the toe cap (200), so that when the protrusion (410b) of the protrusion member (400b) is positioned corresponding to the recess (260) of the toe cap (200), the protrusion member (400b) can be supported by the edge portion (420b).

[0159] The connecting portion (430b) is formed by a region where the protruding portion (410b) and the edge portion (420b) are connected.

[0160] The connecting portion (430b) is formed in a manner that the rear of the connecting portion (430b) is open.

[0161] The engaging portion (430b) may be formed in such a manner as to close an area except for the rear of the engaging portion (430b).

[0162] In the case where the protrusion (410b) has a pentagonal shape, since the edge portion (420b) is arranged along the periphery of the protrusion (410b) except the rear, the rear of the connection portion (430b) is also open. Therefore, the connection portion (430b) is not formed in the area corresponding to the rear of the protrusion (410b). Therefore, the connection portion (430b) is formed by the remaining four faces except the face corresponding to the rear of the protrusion (410b).

[0163] By virtue of the shapes of the protruding portion (410b), the edge portion (420b) and the connecting portion (430b) as described above, the inner side and the rear side of the internal space (411b) of the protruding portion (410b) are open, and the front, the upper part, the lower part and the outer side have a closed shape.

[0164] The boundary lines of the four faces of the connecting portion (430b) are connected to the vertices of the protruding portion (410b). Therefore, when the protruding portion (410b) has a pentagonal shape, the five vertices and the boundary lines of the four faces are connected to each other.

[0165] The protruding member (400b) is located outside the recessed portion (260) of the toe cap (200). The protruding portion (410b) of the protruding member (400b) is located at a position corresponding to the recessed portion (260) of the toe cap (200). Therefore, the recessed portion (260) is located inside the internal space (411b) of the protruding portion (410b).

[0166] The outer skin (140) also protrudes convexly toward the outside through the protruding part (400b). Therefore, the overall appearance of the safety shoe (10) can show the shape of the protruding part (400b).

[0167] The toe cap (200), the protruding member (400b) and the outer skin (140) can be combined with each other and formed into one piece by heat pressing or the like. Therefore, the position of the protruding member (400b) is fixed and the inner space (411b) of the protruding part (410b) can be continuously located outside the recessed part (260), thereby ensuring space for the movement of the little toe (LT).

[0168] As described above, the protruding part (400b) of the safety shoe (10b) according to the third embodiment of the present invention has a shape in which the rear of the engaging part (430b) is open. Therefore, when the wearer wears the safety shoe (10b), the rear of the engaging part (430b) can prevent the little toe (LT) from being caught.

[0169] That is, the safety shoe (10b) according to the third embodiment of the present invention does not have a surface formed behind the protruding part (400b), so that when the safety shoe (10b) is worn, the little toe (LT) can be prevented from being caught on the surface formed behind the protruding part (400b), and thus, a good wearing feeling of the safety shoe (10b) can be ensured.

[0170] The rear-opened protruding member (400b) of the safety shoe (10b) according to the third embodiment of the present invention may also be applied to the safety shoe (10d) according to the fifth embodiment and the safety shoe (10e) according to the sixth embodiment to be described below.

[0171] In detail, as shown in the safety shoe (10d) according to the fifth embodiment to be described below, even when the toe (200d) is not independently provided with a recessed portion and the toe (200d) is located in front of the little toe (LT), the rear-opening protruding component (400b) can be applied.

[0172] In addition, as shown in the safety shoe (10e) according to the sixth embodiment, even if a protrusion (141e) is formed on the inner side of the outer skin (140), the connecting portion (142e) can have a rear open form, that is, the rear of the connecting portion (142e) is open and the front, upper and lower parts except the rear can have a closed form.

[0173] Safety shoes (10c) according to a fourth embodiment of the present invention

[0174] The following reference Figure 12 to Figure 13c , a safety shoe (10c) according to a fourth embodiment of the present invention is described.

[0175] Fig.121 is a perspective view showing a state in which the outer cover is removed in a safety shoe according to a fourth embodiment of the present invention, Fig.13a and Fig.13b is a perspective view of a toe cap of a safety shoe according to a fourth embodiment of the present invention, and Fig.13c FIG. 4 is a plan view of a toe portion of a safety shoe according to a fourth embodiment of the present invention.

[0176] like Figure 8 As shown, the safety shoe (10c) according to the fourth embodiment of the present invention may include the following components: an insole (110) for placing the wearer's foot (F); a midsole (120) disposed at the lower part of the insole (110); a sole (130) disposed at the lower part of the insole (110) and the midsole (120) and constituting the bottom of the safety shoe (10c); a toe cap (200c) disposed inside the front nose of the safety shoe (10c) and including a protruding portion at the position of the little toe (LT) of the foot (F) toward the outside; A protruding portion (270c) protrudes from the ground and has an inner space (271c) formed on the inner side for the little toe (LT) to move; an outer skin (140) surrounds the toe cap (200c) and is arranged on the upper part of the midsole (120) and the sole (130) in a manner of surrounding the foot (F) of the wearer, and forms the shape of a safety shoe (10c); a connecting component (300) is arranged inside the front nose of the safety shoe (10) and is arranged behind the toe cap (200c) and connected to the toe cap (200c).

[0177] The protruding portion (270c) of the safety shoe (10c) according to the fourth embodiment of the present invention is integrally formed at the toe (200c), and only the shape of the toe (200c) and the shape of the coupling component (300) are different from those of the safety shoe (10) according to the first embodiment of the present invention, and the remaining components are the same. Therefore, the description of the same components can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and repeated descriptions are omitted.

[0178] The toe box (200c) may include the following: a front wall (210), which is arranged inside the front nose of the safety shoe (10c) and constitutes the front surface of the toe box (200c); an upper wall (220), which constitutes the upper surface of the toe box (200c); a big toe side wall (230), which constitutes the big toe side surface of the toe box (200c); a little toe side wall (240), which constitutes the little toe side surface of the toe box (200c); a bent portion (250), which is formed by bending and extending at the lower part of the front wall (210), the big toe side wall (230) and the little toe side wall (240), and is formed in a manner that constitutes a part of the bottom surface of the toe box (200c); and a protrusion (270c), which is formed in a manner that protrudes from the rear end of the little toe side wall (240) toward the outside.

[0179] For the toe cap (200c), the front wall (210), the upper wall (220), the big toe side wall (230), and the little toe side wall (240) respectively constitute the front surface, the upper surface, and the two side surfaces of the toe cap (200), and the bent portion (250) formed by bending and extending at the lower part of the front wall (210), the big toe side wall (230), and the little toe side wall (240) is formed in a manner that constitutes a part of the bottom surface of the toe cap.

[0180] The protrusion (270c) protrudes outward from the rear end of the little toe side wall (240) in a manner corresponding to the position of the little toe (LT), and is formed to be recessed in the medial direction.

[0181] The protrusion (270c) is formed to protrude outward with the little toe side wall (240) as a reference so as to form an inner space (271c) on the inner side.

[0182] Specifically, the protrusion (270c) is formed at the position of the outer skin (140) corresponding to the little toe (LT) so as to protrude outward with the little toe side wall (240) as a reference. In this case, the protrusion length of the protrusion (270c) is preferably greater than 2 mm and less than 4 mm.

[0183] The protrusion (270c) has a quadrangular shape as a whole.

[0184] An inner space (271c) is formed inside the inner side of the protrusion (270c), and therefore, the inner side of the little toe side wall (240) is located inside compared to the inner side of the protrusion (270c).

[0185] The internal space (271c) is a space extending from the inner side surface of the little toe side wall (240) to the inner side surface of the protrusion (270c).

[0186] The connecting portion (273c) is formed by the area where the protrusion (270c) is connected to the little toe side wall (240).

[0187] The connecting portion (273c) is formed in a manner that the rear of the connecting portion (273c) is open.

[0188] The engaging portion (273c) may be formed in such a manner as to close an area except for the rear of the engaging portion (273c).

[0189] The protrusion (270c) has a quadrangular shape, and in order to open the rear of the connection part (273c), the connection part (273c) is not formed in the area corresponding to the rear of the protrusion (270c). Therefore, the connection part (273c) is formed by the remaining three surfaces except the surface corresponding to the rear of the protrusion (270c).

[0190] The boundary lines of the three faces of the connecting portion (273c) are connected to the vertices of the protruding portion (270c). Therefore, when the protruding portion (270c) has a quadrangular shape, the four vertices and the boundary lines of the three faces are connected to each other.

[0191] Due to the shapes of the protrusion (270c), the little toe side wall (240) and the connecting portion (273c) as described above, the internal space (271c) of the protrusion (270c) has a shape that is open at the inside and the back and closed at the front, the top, the bottom and the outside.

[0192] The outer skin (140) also protrudes convexly toward the outside through the protruding portion (270c) of the toe (200c). Therefore, the overall appearance of the safety shoe (10c) can show the shape of the protruding portion (270c).

[0193] The coupling component (300) is arranged behind the toe cap (200c) and coupled to the toe cap (200c) in the front-rear direction. Since the safety shoe (10c) according to the fourth embodiment of the present invention does not form a recessed portion on the toe cap (200c), a separate protrusion is not formed on the coupling component (300).

[0194] The protruding portion (270c) of the toe cap (200c) ensures a space for the little toe (LT) of the wearer to move in the safety shoe (10c), thereby preventing the little toe (LT) of the wearer from hitting the inner side of the outer skin (140) or the little toe side wall (240) of the toe cap (200c), thereby preventing the wearer from feeling stuffy or causing pain.

[0195] As described above, since the free movement of the little toe (LT) is guaranteed, the wearer can feel a good wearing feeling even if the outer cover (140) of the safety shoe (10c) is formed of a hard material.

[0196] In addition, since the protruding portion (270c) is formed integrally with the toe portion (200c), the position of the protruding portion (270c) can be easily fixed, thereby facilitating the manufacture of the safety shoe (10c).

[0197] In addition, since the strength of the protrusion (270c) is maintained high, the little toe (LT) can be easily protected from external impact.

[0198] The protruding portion (270c) and the connecting portion (273c) can be formed in one piece in the toe cap (200c). In this case, the protruding portion (270c) and the connecting portion (273c) can be formed by pressing or other processing on the little toe side wall (240) of the toe cap (200c). In this way, when the protruding portion (270c) and the connecting portion (273c) of the toe cap (200c) are formed in one piece, the toe cap (200c) and the protruding portion (270c) and the connecting portion (273c) are formed of the same material.

[0199] In contrast, the protrusion (270c) and the connecting portion (273c) can be manufactured separately from the toe cap (200c). In this case, a recessed portion is formed at the rear end of the toe cap (200c), and the protrusion (270c) and the connecting portion (273c) are arranged in a manner to surround the recessed portion. Therefore, the space formed by opening the recessed portion and on the inner side of the protrusion (270c) and the connecting portion (273c) is the internal space (271c). The protrusion (270c) and the connecting portion (273c) can be bonded to the toe cap (200c) using an adhesive or the like. In this way, when the protrusion (270c) and the connecting portion (273c) are formed separately in the toe cap (200c), the toe cap (200c) and the protrusion (270c) and the connecting portion (273c) are formed of materials different from each other. However, the protrusion (270c) and the connecting portion (273c) can be formed of the same material.

[0200] Safety shoes (10d) according to a fifth embodiment of the present invention

[0201] The following reference Fig.14 , a safety shoe (10d) according to a fifth embodiment of the present invention is described.

[0202] Fig.14 1 is a diagram showing a state in which a wearer's foot is worn in the safety shoe according to the fifth embodiment of the present invention.

[0203] like Fig.14As shown in the figure, the safety shoe (10d) according to the fifth embodiment of the present invention may include the following components: an insole (110) for placing the wearer's foot (F); a midsole (120) disposed at the lower part of the insole (110); a sole (130) disposed at the lower part of the insole (110) and the midsole (120) and constituting the bottom of the safety shoe (10d); an outer cover (140) disposed at the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F). 0), and forming the shape of a safety shoe (10d); a toe cap (200d), which is arranged inside the front nose of the safety shoe (10d) and is located in front of the little toe (LT) of the foot (F); and a protruding part (400), which is arranged on the inner side of the outer skin (140) in a manner corresponding to the little toe (LT) of the foot (F), and protrudes outwardly to form an inner space (411) on the inner side for the little toe (LT) to move.

[0204] The safety shoe (10d) according to the fifth embodiment of the present invention has the same structure as the safety shoe (10d) according to the first embodiment of the present invention except that the shape of the toe (200d) is different. Therefore, the description of the same structure can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and the repeated description is omitted.

[0205] The toe cap (200d) may include the following: a front wall (210), constituting the front surface of the toe cap (200d); an upper wall (220), constituting the upper surface of the toe cap (200d); a big toe side wall (230), constituting the big toe side surface of the toe cap (200d); a little toe side wall (240), constituting the little toe side surface of the toe cap (200); and a bending portion (250), which is formed by bending and extending at the lower part of each of the front wall (210), the big toe side wall (230) and the little toe side wall (240), and is formed in a manner that constitutes a part of the bottom surface of the toe cap (200).

[0206] In the safety shoe (10d) according to the fifth embodiment, the toe portion (200d) is not provided with a recessed portion separately.

[0207] The rear end of the little toe side wall (240) of the toe cap (200d) is located in front of the little toe (LT). Therefore, the toe cap (200d) has a shape that surrounds only a part of the toes of the foot (F).

[0208] A small toe side wall (240) of the toe cap (200d) is positioned on the inner side of the protruding part (400).

[0209] The little toe (LT) can move outward from the inner space (411) of the protruding portion (410). That is, since the inner space (411) ensures space, the free movement of the little toe (LT) is guaranteed.

[0210] Since the rear end of the little toe side wall (240) of the toe cap (200d) is located in front of the little toe (LT), the little toe (LT) moving in the internal space (411) is not hindered from moving through the little toe side wall (240).

[0211] As described above, the safety shoe (10d) according to the fifth embodiment of the present invention prevents the wearer from feeling discomfort in the toes and ensures a good wearing feeling by making the toe (200d) not surround the little toe (LT) and the protruding part (400) ensures a space for the little toe (LT) to move, thereby without increasing the size of the safety shoe (10d) or the weight of the safety shoe (10d).

[0212] Safety shoes (10e) according to a sixth embodiment of the present invention

[0213] The following reference Fig.15 and Fig.16 , a safety shoe (10e) according to a sixth embodiment of the present invention is described.

[0214] Fig.15 is a perspective view of an enlarged front nose portion of a safety shoe according to a sixth embodiment of the present invention, and Fig.16 1 is a perspective view showing a state in which the outer cover is removed in the safety shoe according to the sixth embodiment of the present invention.

[0215] like Fig.15 and Fig.16 As shown, the safety shoe (10e) according to the sixth embodiment of the present invention may include the following: an insole (110) for placing the wearer's foot (F); a midsole (120) arranged at the lower part of the insole (110); a sole (130) arranged at the lower part of the insole (110) and the midsole (120) and constituting the bottom of the safety shoe (10e); and an outer skin (140e) arranged at the upper part of the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F) to form the shape of the safety shoe (10e), and including a protrusion (141e) arranged at a position corresponding to the little toe (LT) and protruding convexly outward from the inner side thereof to form an inner space (143e) for the little toe (LT) to move on the inner side.

[0216] The safety shoe (10e) according to the sixth embodiment of the present invention is different only in that the protrusion (141e) is integrally formed on the outer skin (140e), and the remaining components have the same structure as the safety shoe (10e) according to the first embodiment of the present invention. Therefore, the description of the same structure can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and the repeated description is omitted.

[0217] The outer skin (140e) may include: a protrusion (141e) forming an internal space (143e) on the inner side and convexly formed toward the outer side; and a connecting portion (142e) formed by a region where the protrusion (141e) and the outer skin (140e) are connected.

[0218] The protrusion (141e) is formed to protrude outward based on the outer skin (140e) to form an internal space (143e) inside. In this case, the protrusion length of the protrusion (141e) is preferably not less than 2 mm and not more than 4 mm.

[0219] The protrusion (141e) may have a pentagonal shape as a whole. In this case, the rear of the protrusion (141e) is preferably formed to have the longest side among the five sides of the pentagon of the protrusion (141e).

[0220] An internal space (143e) is formed inside the inner side of the inner side of the protrusion (141e), and therefore, the inner side of the outer skin (140e) is located inside compared to the inner side of the protrusion (141e).

[0221] The internal space (143e) is a space from the inner side surface of the outer skin (140e) to the inner side surface of the protrusion (141e).

[0222] The connecting portion (142e) is formed by the area where the protrusion (141e) is connected to the outer skin (140e).

[0223] In the case where the protrusion (141e) has a pentagonal shape, the connecting portion (142e) may be formed with five faces in a manner corresponding to the pentagonal protrusion (141e). Therefore, the connecting portion (142e) is entirely formed in a closed manner.

[0224] The boundary line of the surface of the connecting portion (142e) is connected to the apex of the protruding portion (141e). Therefore, in the case where the protruding portion (141e) has a pentagonal shape, five vertices and five boundary lines of the surface are connected to each other.

[0225] The protrusion (400) is located outside the recess (260) of the toe cap (200). Specifically, the protrusion (141e) is located at a position corresponding to the recess (260) of the toe cap (200). Therefore, the recess (260) is located inside the internal space (143e) of the protrusion (141e).

[0226] The protruding portion (141e) and the connecting portion (142e) can be formed on the outer skin (140e) by subjecting the outer skin (140e) to heat treatment, pressing, etc.

[0227] As described above, when the outer skin (140e) is provided with the protruding portion (141e) and the connecting portion (142e), no separate protruding component is required, so that the manufacturing process is simple and the movement of the protruding component and the deviation of the position of the protruding portion (141e) can be prevented.

[0228] Safety shoes (10f) according to a seventh embodiment of the present invention

[0229] The following reference Fig.17 , a safety shoe (10f) according to a seventh embodiment of the present invention is described.

[0230] Fig.17 1 is a perspective view showing a state in which the outer cover is removed in the safety shoe according to the seventh embodiment of the present invention.

[0231] like Fig.17 As shown, the safety shoe (10f) according to the seventh embodiment of the present invention may include the following components: an insole (110) for placing the wearer's foot (F); a midsole (120) disposed at the bottom of the insole (110); a sole (130) disposed at the bottom of the insole (110) and the midsole (120) and forming the bottom of the safety shoe (10f); an outer cover (140) disposed at the top of the midsole (120) and the sole (130) in a manner of surrounding the wearer's foot (F) and forming the shape of the safety shoe (10f); a toe cap (20 0), including a recessed portion (260) formed in a forward direction at the position of the little toe (LT) of the foot (F); a protruding component (400) arranged on the inner side of the outer skin (140) in a manner corresponding to the little toe (LT) of the foot (F), and protruding outward to form an inner space (411) on the inner side for the little toe (LT) to move; and a combining component (300ff) arranged inside the front nose of the safety shoe (10f) and arranged behind the toe (200) and combined with the toe (200).

[0232] The safety shoe (10f) according to the seventh embodiment of the present invention has the same structure as the safety shoe (10) according to the first embodiment of the present invention except that the shape of the coupling member (300ff) is different. Therefore, the description of the same structure can be replaced by the description of the safety shoe (10) according to the first embodiment of the present invention, and the repeated description is omitted.

[0233] The coupling component (300f) is arranged at the rear of the toe cap (200) and coupled to the toe cap (200) in the front-rear direction.

[0234] The connecting component (300f) is formed of a soft material. Therefore, the connecting component (300f) plays a role in preventing the wearer's instep from hitting the rear of the upper wall (220) of the toe box (200) and causing pain.

[0235] The little toe (LT) side of the connecting part (300f) is formed short so that the connecting part (300f) is not located in the recessed part (260). That is, the connecting part (300f) does not have a little toe side surface corresponding to the little toe (LT). Therefore, the recessed part (260) remains an empty space as it is.

[0236] As described above, since the coupling member ( 300 f ) does not have a portion corresponding to the recessed portion ( 260 ), only the recessed portion ( 260 ) is positioned in the inner space ( 411 ) of the protruding portion ( 410 ).

[0237] Since the coupling member (300f) is not located in the recessed portion (260), there is an advantage that the freedom of the little toe (LT) is ensured by the space in the recessed portion (260).

[0238] The coupling component (300f) can also be applied to the safety shoes (10a-10e) according to the second to sixth embodiments.

[0239] As described above, although the present invention has been described with reference to the preferred embodiments, a person skilled in the art may make various modifications or variations to the present invention without departing from the scope of the invention and the scope of the invention as described in the above claims.
