[0058] As illustrated in FIGS. 1 to 7b, the safety shoe (10) according to the first embodiment of the present disclosure is a safety shoe (10) worn on a foot (F) of a wearer, and may include: an insole (110) on which the foot (F) of the wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10); an outer shell (140) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer and forming the shape of the safety shoe (10); a toe cap (200) having a concave portion (260) formed concavely in the forward direction at a position corresponding to a little toe (LT) of the foot (F); a protruding member (400) provided on an inner side of the outer shell (140) so as to be disposed at a position corresponding to the little toe (LT) of the foot (F), and protruding convexly outward to form an internal space (411) therewithin for allowing movement of the little toe (LT) within the internal space; a coupling member (300) provided inside a front toe part of the safety shoe (10), having a convex portion (310) having a shape corresponding to the concave portion (260) and fitted into the concave portion (260), and disposed behind the toe cap (200) to be coupled to the toe cap (200).

[0059] The insole (110) is a part where the foot (F) of the wearer rests and touches the bottom of the foot, and is located on the midsole (120).

[0060] Additionally, the insole (110) is located on a bent portion (250) of the toe cap (200).

[0061] The midsole (120) and the outsole (130) are provided under the insole (110).

[0062] The outsole (130) forming the bottom of the safety shoe (10) is provided under the midsole (120).

[0063] The outer shell (140) covering the foot (F) of the wearer is provided on the midsole (120) and the outsole (130).

[0064] The outer shell (140) covers the foot (F) of the wearer and an outer surface of the toe cap (200), and forms an outer surface and the shape of the safety shoe (10).

[0065] To protect the foot (F) of the wearer from falling objects and sharp objects, the outer shell (140) may be made of a hard material.

[0066] As described above, the safety shoe (10) may be provided with the midsole (120) and the outsole (130) under the midsole (120), thereby having a multilayer outsole structure in which the outsole (130) forms the bottom of the safety shoe (10).

[0067] On the contrary, the safety shoe (10) may be provided with only the midsole (120) or the

[0068] outsole (130), thereby having a single-layer outsole structure in which the midsole (120) or the outsole (130) forms the bottom of the safety shoe (10).

[0069] As illustrated in FIGS. 3 to 5b, the toe cap (200) is provided inside the front toe part of the safety shoe (10), and may include: a front wall (210) forming a front surface of the toe cap (200); an upper wall (220) forming an upper surface of the toe cap (200); a big toe side wall (230) forming a big toe side surface of the toe cap (200); a little toe side wall (240) forming a little toe side surface of the toe cap (200); the bent portion (250) formed by bending and extending from a lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240), and forming a part of a bottom surface of the toe cap (200); and a concave portion (260) formed concavely in the forward direction of the toe cap (200) from a rear end of the little toe side wall (240) to open at least a part of the rear end of the little toe side wall (400).

[0070] In the toe cap (200), the front wall (210), the upper wall (220), the big toe side wall (230), the little toe side wall (240) form the front surface, upper surface, and opposite side surfaces of the toe cap (200), respectively. The bent portion (250) is formed by bending and extending from the lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240) to form a part of the bottom surface of the toe cap. At the rear end of the little toe side wall (240), the concave portion (260) is formed concavely from the rear end of the little toe side wall (240) in the forward direction of the toe cap (200) to open at least a part of the rear end of the little toe side wall (240).

[0071] With the above-described configuration, the toe cap (200) has a shape in which a part of the bottom surface thereof is open, and the front surface, upper surface, and opposite side surfaces thereof are closed 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 the part of the little toe side wall (240) is opened by the concave portion (260), a region on the side where the concave portion (260) is formed on the little toe side wall (240) is not closed but is open.

[0072] The front wall (210), the upper wall (220), the big toe side wall (230), and the little toe side wall (240) are formed integrally to extend from each other, and each of the front wall (210), the upper wall (220), the big toe side wall (230), and the little toe side wall (240) is processed into a curved surface, thereby having an overall streamlined shape that becomes narrower in width in the forward direction of the toe cap (200).

[0073] The bent portion (250) is formed by bending and extending from the lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240).

[0074] The bent portion (250) forms only a part of the bottom surface of the toe cap (200). The bending portion (250) has an overall U shape, as illustrated in FIGS. 5a and 5b. Therefore, the bottom surface of the toe cap (200) has a U shape with an open space.

[0075] The bent portion (250) is bent toward the bottom surface of the toe cap (200) so that the angle between an inner surface of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240) and an upper surface of the bent portion (250) is equal to or greater than 90. In this case, the bent portion (250) has a width of several mm to several tens of mm.

[0076] The toe cap (200) may be made of a hard material such as metal to protect the foot (F) from falling objects.

[0077] When the toe cap (200) is provided in the safety shoe (10), the insole (110) is located on the bent portion (250).

[0078] The front wall (210) forms the front surface of the toe cap (200) and has a shape that becomes narrower in width in the forward direction. In this case, the front wall (210) has a curve with curvature, so the front wall (210) has a streamlined shape.

[0079] The upper wall (220) extends from a central rear end of the front wall (210) and forms the upper surface of the toe cap (200).

[0080] The upper wall (220) covers top of the toes of the wearer, thereby protecting the toes from falling objects.

[0081] The big toe side wall (230) extends from a big toe side rear end of the front wall (210) and forms a side surface of the toe cap (200). As illustrated in FIGS. 1 to 5b, when the safety shoe (10) is a right-foot safety shoe (10), the big toe side wall (230) of the toe cap (200) forms a left side surface of the toe cap (200).

[0082] The big toe side wall (230) has a shape that is inclined toward a big toe of the wearer in the rearward direction. In this case, the big toe side wall (230) has a curve with curvature, so the big toe side wall has a streamlined shape.

[0083] The little toe side wall (240) extends from a little toe side rear end of the front wall (210) and forms a side surface of the toe cap (200). When the safety shoe (10) is a right-foot safety shoe (10), the little toe side wall (240) of the toe cap (200) forms a right side surface of the toe cap (200).

[0084] The little toe side wall (340) is provided with the concave portion (260).

[0085] The concave portion (260) is formed concavely from the rear end of the little toe side wall (240) in the forward direction of the toe cap (200). Therefore, the concave portion (260) opens at least a part of the rear end of the little toe side wall (240).

[0086] As illustrated in FIG. 6, the concave portion (260) functions to prevent the little toe (LT) from touching the little toe side wall (240) of the toe cap (200) when the wearer wears the safety shoe (10).

[0087] In other words, the concave portion (260) is formed at a position corresponding to where the little toe (LT) is to be located when the wearer wears the safety shoe (10) provided with the toe cap (200), thereby preventing the little toe (LT) from touching the little toe side wall (240) of the toe cap (200).

[0088] The concave portion (260) is formed above the bent portion (250).

[0089] The concave portion (260) is formed at a position spaced apart from the bent portion (250) upward, so a spacing portion (241) is formed between the concave portion (260) and the bent portion (250).

[0090] The spacing portion (241) is a part of the little toe side wall (240) that connects the bent portion (250) and the concave portion (260) to each other at a lower part of the concave portion (260).

[0091] In other words, as the concave portion (260) is formed at a position spaced apart from the bent portion (250) upward, the spacing portion (241) is formed between the concave portion (260) and the bent portion (250), and the spacing portion (241) is a part of the little toe side wall (240) that connects the bent portion (250) and the concave portion (260) at the lower part of the concave portion (260).

[0092] As described above, as the spacing portion (241) is formed between the concave portion (260) and the bent portion (250), a curved shape of the concave portion (260) can be easily formed.

[0093] Additionally, due to the spacing portion (241), the function of the concave portion (260), which alleviates external impact applied to the toe cap (200), can be further maximized.

[0094] With the configuration of the concave portion (260) described above, the big toe side wall (230) and the little toe side wall (240) of the toe cap (200) have different shapes. 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.

[0095] The protruding member (400) is provided on an outer side of the toe cap (200) and the inner

[0096] side of the outer shell (140) so as to be disposed 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 shell (140).

[0097] The protruding member (400) may include a protrusion portion (410) having the internal space (411) therewithin and formed convexly outward, a rim portion (420) provided along the perimeter of the protrusion portion (410), and a joint portion (430) formed by a region where the protrusion portion (410) and the rim portion (420) are connected to each other.

[0098] The protrusion portion (410) is formed convexly outward from the rim portion (420) so that the internal space (411) is formed within the protrusion portion.

[0099] In detail, the protrusion portion (410) is formed to protrude convexly outward from the rim portion (420) at a position corresponding to the little toe (LT) on the outer shell (140). In this case, it is preferable that a protruding length of the protrusion portion (410) is in the range of 2 mm to 4 mm.

[0100] The protrusion portion (410) may have an overall pentagonal shape. In this case, it is preferable that a rear part of the protrusion portion (410) is formed to have the longest side among five sides of the pentagonal shape of the protrusion portion (410).

[0101] The rim portion (420) is provided along the perimeter of the protrusion portion (410).

[0102] The rim portion (420) has a flat shape, and the protrusion portion (410) protrudes outward from the rim portion (420).

[0103] The rim portion (420) has an outer surface located further inward than an outer surface of the protrusion portion (410).

[0104] The internal space (411) is formed within an inner surface of the protrusion portion (410), so an inner surface of the rim portion (420) is located further inward than the inner surface of the protrusion portion (410).

[0105] The internal space (411) is a space defined from the inner surface of the rim portion (420) to the inner surface of the protrusion portion (410).

[0106] When the inner surface of the rim portion (420) is in contact with the outer surface of the toe cap (200) and the protrusion portion (410) of the protruding member (400) is positioned to correspond to the concave portion (260) of the toe cap (200), the protruding member (400) is supported through the rim portion (420).

[0107] The joint portion (430) is formed by a region where the protrusion portion (410) and the rim portion (420) are connected to each other.

[0108] When the protrusion portion (410) has a pentagonal shape, the joint portion (430) may be composed of five surfaces to correspond to the pentagonal shaped protrusion portion (410). Therefore, the joint portion (430) is formed to be entirely closed.

[0109] The boundary lines of the surfaces of the joint portion (430) are connected to vertices of the protrusion portion (410). Therefore, when the protrusion portion (410) has a pentagonal shape, five vertices are connected to the boundary lines of five surfaces.

[0110] The protruding member (400) is located on an outer side of the concave portion (260) of the toe cap (200). In detail, as illustrated in FIG. 6, the protrusion portion (410) of the protruding member (400) is located at a position corresponding to the concave portion (260) of the toe cap (200). Therefore, the concave portion (260) is located on an inner side of the internal space (411) of the protrusion portion (410).

[0111] Due to the protruding member (400), the outer shell (140) also protrudes convexly outward. Therefore, the shape of the protruding member (400) may be seen on the overall appearance of the safety shoe (10).

[0112] The toe cap (200), the protruding member (400), and the outer shell (140) may be integrally formed into a single body by being joined to each other by means of thermal compression or the like. Therefore, the position of the protruding member (400) is fixed, so the internal space (411) of the protrusion portion (410) is continuously positioned outside the concave portion (260), thereby securing a space that ensures movement of the little toe (LT).

[0113] The coupling member (300) is disposed behind the toe cap (200) and is coupled to the toe cap (200) in the forward-rearward direction.

[0114] The convex portion (310) is provided on a side of the coupling member (300).

[0115] The convex portion (310) has a shape corresponding to the concave portion (260).

[0116] The convex portion (310) is provided on a little toe side of the coupling member (300) at a position corresponding to the concave portion (260).

[0117] The coupling member (300) and the toe cap (200) are coupled to each other in the forward-rearward direction with the convex portion (310) fitted into the concave portion (260).

[0118] The coupling member (300) may be made of a soft material. Therefore, the coupling member (300) functions to prevent the instep of the wearer from touching a rear part of the upper wall (220) of the toe cap (200) and feeling pain.

[0119] When the convex portion (310) and the concave portion (260) are engaged with each other by the coupling member (300), the internal space (411) of the protrusion portion (410) is located on an outer side of the convex portion (310).

[0120] According to the first embodiment of the present disclosure, the safety shoe (10) described above has the concave portion (260), the convex portion (310), and the protrusion portion (410) that are located at a position corresponding to the little toe (LT).

[0121] Due to the concave portion (260), the convex portion (310), and the protrusion portion (410), a space for movement of the little toe (LT) of the wearer is secured. Therefore, the little toe (LT) can be prevented from touching an inner surface of the outer shell (140) or the little toe side wall (240) of the toe cap (200) and feeling stuffy or pain.

[0122] In detail, in the case of conventional safety shoes, since an outer shell or a toe cap of the shoes is made of a hard material, there is a problem in which the wearer feels discomfort when the toes of the wearer touches an inner side of the outer shell or an inner side of the toe cap. In particular, in the case of safety shoes equipped with a toe cap, when the toe cap is made large to solve this problem, the safety shoes becomes larger and heavier, resulting in a problem of poor fitting.

[0123] In order to solve the above problem, in the case of the present disclosure, since the protrusion portion (410) having the internal space (411) therewithin is separately provided inside the safety shoe (10), a space is formed for the little toe (LT) to be moved outward. Therefore, the space can be secured without needing to make the size of the safety shoe (10) or the toe cap (200) large, thereby improving wearing comfort while maintaining fitting of the safety shoe (10).

[0124] Additionally, since the coupling member (300) and the convex portion (310) are made of a soft material, the degree of freedom of the little toe (LT) can be guaranteed even when the convex portion (310) exists. That is, since the convex portion (310) is made of a soft material, when the little toe (LT) is moved outward, the convex portion (310) is also moved outward within the internal space (411), thereby ensuring free movement of the little toe (LT).

[0125] As described above, since free movement of the little toe (LT) is guaranteed, the wearer can feel a high level of wearing comfort even though the outer shell (140) of the safety shoe (10) is made of a hard material.

[0126] The safety shoe (10) according to the first embodiment of the present disclosure described above can realize securement of the space for the little toe (LT) through the protruding member (400) even in a structure that does not have the toe cap (200).

Safety Shoe (10a) According to Second Embodiment of the Present Disclosure

[0127] Hereinafter, a safety shoe (10a) according to a second embodiment of the present disclosure will be described with reference to FIG. 8.

[0128] FIG. 8 is a perspective view illustrating a state in which an outer shell is removed from a safety shoe according to a second embodiment of the present disclosure.

[0129] As illustrated in FIG. 8, the safety shoe (10a) according to the second embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10a); an outer shell (140) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer and forming the shape of the safety shoe (10a); a toe cap (200) having a concave portion (260) formed concavely in the forward direction at a position corresponding to a little toe (LT) of the foot (F); a protruding member (400) provided on an inner side of the outer shell (140) so as to be disposed at a position corresponding to the little toe (LT) of the foot (F), and protruding convexly outward to form an internal space (411) therewithin for allowing movement of the little toe (LT) within the internal space; a coupling member (300) provided inside a front toe part of the safety shoe (10a), having a convex portion (310) having a shape corresponding to the concave portion (260) and fitted into the concave portion (260), and disposed behind the toe cap (200) to be coupled to the toe cap (200); and a soft member (470) provided inside a protrusion portion (410) of the protruding member (400).

[0130] The safety shoe (10a) according to the second embodiment of the present disclosure remains the same as the safety shoe (10) according to the first embodiment of the present disclosure described above, except that the soft member (470) is additionally included. Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0131] The soft member (470) is provided inside the protrusion portion (410) of the protruding member (400).

[0132] In detail, the soft member (470) may be provided in an internal space (411) formed within the protrusion portion (410). In this case, the soft member (470) may be provided to fill at least a part of the internal space (411).

[0133] The soft member (470) may be made of a soft, smooth, and elastic material. For example, the soft member (470) may be made of sponge, EVA, or the like.

[0134] As described above, the soft member (470) is provided in the internal space (411) to function to prevent the little toe (LT) from directly touching an inner side of the protrusion portion (410), thereby enhancing wearing comfort.

[0135] That is, since the little toe (LT) directly touches the soft and fluffy soft member (470), the wearer can feel a higher level of wearing comfort compared to when the little toe (LT) directly touches the inner side of the protrusion portion (410) of the relatively hard protruding member (400).

[0136] The soft member (470) may be provided by being bonded to the inner side of the protrusion portion (10) of the protruding member (400) using an adhesive or the like.

[0137] The soft member (470) may also be applied to the internal space of the safety shoe (10) according to the first embodiment of the present disclosure described above, and internal spaces (411), (411b), (271c), and (143e) of safety shoes (10b) to (10e) according to third to sixth embodiments, which will be described later.

Safety Shoe (10b) According to Third Embodiment of the Present Disclosure

[0138] Hereinafter, a safety shoe (10b) according to a third embodiment of the present disclosure will be described with reference to FIGS. 9 to 11b.

[0139] FIG. 9 is an enlarged perspective view illustrating a front toe part of a safety shoe according to a third embodiment of the present disclosure. FIG. 10 is a perspective view illustrating the position of a protruding member in the safety shoe according to the third embodiment of the present disclosure. FIGS. 1la and 11b are perspective views illustrating the protruding member of the safety shoe according to the third embodiment of the present disclosure.

[0140] As illustrated in FIGS. 9 to 11b, the safety shoe (10b) according to the third embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10b); an outer shell (140) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer and forming the shape of the safety shoe (10b); a toe cap (200) having a concave portion (260) formed concavely in the forward direction at a position corresponding to a little toe (LT) of the foot (F); a protruding member (400b) provided on an inner side of the outer shell (140) so as to be disposed at a position corresponding to the little toe (LT) of the foot (F), and protruding convexly outward to form an internal space (411) therewithin for allowing movement of the little toe (LT) within the internal space; a coupling member (300) provided inside a front toe part of the safety shoe (10b), having a convex portion (310) having a shape corresponding to the concave portion (260) and fitted into the concave portion (260), and disposed behind the toe cap (200) to be coupled to the toe cap (200).

[0141] The safety shoe (10b) according to the third embodiment of the present disclosure remains the same as the safety shoe (10) according to the first embodiment of the present disclosure, except that the shape of the protruding member (400b) is different from the protruding member (400) of the safety shoe according to the first embodiment of the present disclosure. Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0142] The protruding member (400b) is provided on an outer side of the toe cap (200) and the inner side of the outer shell (140) so as to be disposed 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 shell (140).

[0143] The protruding member (400b) may include a protrusion portion (410b) having the internal space (411b) therewithin and formed convexly outward, a rim portion (420b) provided along the perimeter of the protrusion portion (410b), and a joint portion (430b) formed by a region where the protrusion portion (410b) and the rim portion (420b) are connected to each other.

[0144] The protrusion portion (410b) is formed convexly outward from the rim portion (420b) so that the internal space (411b) is formed within the protrusion portion.

[0145] The protrusion portion (410b) is formed to protrude convexly outward from the rim portion (420b) at a position corresponding to the little toe (LT) on the outer shell (140). In this case, it is preferable that a protruding length of the protrusion portion (410b) is in the range of 2 mm to 4 mm.

[0146] The protrusion portion (410b) may have an overall pentagonal shape.

[0147] The rim portion (420b) is provided along at least a part of the perimeter of the protrusion portion (410b).

[0148] As an example, the rim portion (420b) may be provided along front, upper, and lower parts of the protrusion portion (410b) except for a rear part of the protrusion portion. The rim portion (420b) is provided along the perimeter of the protrusion portion (410b) except for the rear part of the protrusion portion.

[0149] The rim portion (420b) has a flat shape, and the protrusion portion (410b) protrudes outward from the rim portion (420b).

[0150] The rim portion (420b) has an outer surface located further inward than an outer surface of the protrusion portion (410b).

[0151] The internal space (411b) is formed within an inner surface of the protrusion portion (410b), so an inner surface of the rim portion (420b) is located further inward than the inner surface of the protrusion portion (410b).

[0152] The internal space (411b) is a space defined from the inner surface of the rim portion (420b) to the inner surface of the protrusion portion (410b).

[0153] When the inner surface of the rim portion (420b) is in contact with the outer surface of the toe cap (200) and the protrusion portion (410b) of the protruding member (400b) is positioned to correspond to the concave portion (260) of the toe cap (200), the protruding member (400b) is supported through the rim portion (420b).

[0154] The joint portion (430b) is formed by a region where the protrusion portion (410b) and the rim portion (420b) are connected to each other.

[0155] The joint portion (430b) is formed so that a rear part of the joint portion (430b) is open.

[0156] The joint portion (430b) may be formed so that a region except for the rear part of the joint portion (430b) is closed.

[0157] When the protrusion portion (410b) has a pentagonal shape, since the rim portion (420b) is provided along the perimeter of the protrusion portion (410b) except for the rear part of the protrusion portion, the rear part of the joint portion (430b) is also open. Therefore, the joint portion (430b) is not formed in a region corresponding to the rear part of the protrusion portion (410b). As a result, the joint portion (430b) is composed of four surfaces excluding a surface corresponding to the rear part of the protrusion portion (410b).

[0158] Due to the shapes of the protrusion portion (410b), the rim portion (420b), and the joint portion (430b) as described above, the internal space (411b) of the protrusion portion (410b) has a shape in which inner and rear sides are open and front, upper, lower, and outer sides are closed.

[0159] The boundary lines of the fourth surfaces of the joint portion (430) are connected to vertices of the protrusion portion (410b). Therefore, when the protrusion portion (410b) has a pentagonal shape, five vertices are connected to the boundary lines of the four surfaces.

[0160] The protruding member (400b) is located on an outer side of the concave portion (260) of the toe cap (200). The protrusion portion (410b) of the protruding member (400b) is located at a position corresponding to the concave portion (260) of the toe cap (200). Therefore, the concave portion (260) is located on the inner side of the internal space (411b) of the protrusion portion (410b).

[0161] Due to the protruding member (400b), the outer shell (140) also protrudes convexly outward. Therefore, the shape of the protruding member (400b) may be seen on the overall appearance of the safety shoe (10).

[0162] The toe cap (200), the protruding member (400b), and the outer shell (140) may be integrally formed into a single body by being joined to each other by means of thermal compression or the like. Therefore, the position of the protruding member (400b) is fixed, so the internal space (411b) of the protrusion portion (410b) is continuously positioned outside the concave portion (260), thereby securing a space that ensures movement of the little toe (LT).

[0163] As described above, the protruding member (400b) of the safety shoe (10b) according to the third embodiment of the present disclosure has a shape in which the rear part of the joint portion (430b) is open. Accordingly, when the wearer wears the safety shoe (10b), the little toe (LT) can be prevented from being caught by the rear part of the joint portion (430b).

[0164] That is, according to the safety shoe (10b) according to the third embodiment of the present disclosure, by eliminating the surface corresponding to the rear part of the protruding member (400b), the little toe (LT) can be prevented from being caught on the surface corresponding to the rear part of the protruding member (400b) when wearing the safety shoe (10b), thereby ensuring a high level of wearing comfort of the safety shoe (10b).

[0165] The protruding member (400b) with the open rear part of the safety shoe (10b) according to the third embodiment of the present disclosure described above may also be applied to a safety shoe (10d) according to a fifth embodiment and a safety shoe (10e) according to a sixth embodiment, which will be described later

[0166] In detail, as in the safety shoe (10d) according to the fifth embodiment which will be described later, even when a toe cap (200d) is not provided with a separate concave portion and the toe cap (200d) is positioned in front of the little toe (LT), the protruding member (400b) with the open rear part may be applied.

[0167] In addition, as in the safety shoe (10e) according to the sixth embodiment, even when a protrusion portion (141e) is formed on an inner side of an outer shell (140), a joint portion (142e) may have a shape with an open rear part, that is, a shape in which the rear part of the joint portion (142e) is open and front, upper, and lower parts thereof excluding the rear part are closed.

Safety Shoe (10c) According to Fourth Embodiment of the Present Disclosure

[0168] Hereinafter, a safety shoe (10c) according to a fourth embodiment of the present disclosure will be described with reference to FIGS. 12 to 13c.

[0169] FIG. 12 is a perspective view illustrating a state in which an outer shell is removed from a safety shoe according to a fourth embodiment of the present disclosure. FIGS. 13a and 13b are perspective views illustrating a toe cap of the safety shoe according to the fourth embodiment of the present disclosure. FIG. 13c is a plan view illustrating the toe cap of the safety shoe according to the fourth embodiment of the present disclosure.

[0170] As illustrated in FIG. 8, the safety shoe (10c) according to the fourth embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10c); a toe cap (200c) provided inside a front toe part of the safety shoe (10c), and having a protrusion portion (270c) protruding convexly outward at a position corresponding to a little toe (LT) of the foot (F) to form an internal space (271c) therewithin for allowing movement of the little toe (LT) within the internal space; an outer shell (140) covering the toe cap (200c), provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer, and forming the shape of the safety shoe (10c); and a coupling member (300) provided inside the front toe part of the safety shoe (10), and disposed behind the toe cap (200c) to be coupled to the toe cap (200c).

[0171] The safety shoe (10c) according to the fourth embodiment of the present disclosure remains the same as the safety shoe (10) according to the first embodiment of the present disclosure, except that the protrusion portion (270c) is formed integrally with the toe cap (200c), so the shapes of the toe cap (200c) and the coupling member (300) are different. Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0172] The toe cap (200c) is provided inside the front toe part of the safety shoe (10c), and may include: a front wall (210) forming a front surface of the toe cap (200c); an upper wall (220) forming an upper surface of the toe cap (200c); a big toe side wall (230) forming a big toe side surface of the toe cap (200c); a little toe side wall (240) forming a little toe side surface of the toe cap (200c); a bent portion (250) formed by bending and extending from a lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240), and forming a part of a bottom surface of the toe cap (200c); and the protrusion portion (270c) formed to protrude convexly outward from a rear end of the little toe side wall (240).

[0173] In the toe cap (200c), the front wall (210), the upper wall (220), the big toe side wall (230), the little toe side wall (240) form the front surface, upper surface, and opposite side surfaces of the toe cap (200), respectively. The bent portion (250) is formed by bending and extending from the lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240) to form a part of the bottom surface of the toe cap.

[0174] The protrusion portion (270c) is formed convexly outward and concavely inward from the rear end of the little toe side wall (240) to correspond to the position of the little toe (LT).

[0175] The protrusion portion (270c) is formed convexly outward from the little toe side wall (240) so that the internal space (271c) is formed within the protrusion portion.

[0176] In detail, the protrusion portion (270c) is formed to protrude convexly outward from the little toe side wall (240) at a position corresponding to the little toe (LT) on the outer shell (140). In this case, it is preferable that a protruding length of the protrusion portion (270c) is in the range of 2 mm to 4 mm.

[0177] The protrusion portion (270c) may have an overall quadrangular shape.

[0178] The internal space (271c) is formed within an inner surface of the protrusion portion (270c), so an inner surface of the little toe side wall (240) is located further inward than the inner surface of the protrusion portion (270c).

[0179] The internal space (271c) is a space defined from the inner surface of the little toe side wall (240) to the inner surface of the protrusion portion (270c).

[0180] The joint portion (273c) is formed by a region where the protrusion portion (270c) and the little toe side wall (240) are connected to each other.

[0181] The joint portion (273c) is formed so that a rear part of the joint portion (273c) is open.

[0182] The joint portion (273c) may be formed so that a region except for the rear part of the joint portion (273c) is closed.

[0183] In order for the protrusion portion (270c) to have a quadrangular shape and the rear part of the joint portion (273c) to be open, the joint portion (273c) is not formed in a region corresponding to the rear part of the protrusion portion (270c). As a result, the joint portion (273c) is composed of three surfaces excluding a surface corresponding to the rear part of the protrusion portion (270c).

[0184] The boundary lines of the three surfaces of the joint portion (273c) are connected to vertices of the protrusion portion (270c). Therefore, when the protrusion portion (270c) has a quadrangular shape, four vertices are connected to the boundary lines of the three surfaces.

[0185] Due to the shapes of the protrusion portion (270c), the little toe side wall (240), and the joint portion (273c) as described above, the internal space (271c) of the protrusion portion (270c) has a shape in which inner and rear sides are open and front, upper, lower, and outer sides are closed.

[0186] Due to the protrusion portion (270c) of the toe cap (200c), the outer shell (140) also protrudes convexly outward. Therefore, the shape of the protrusion portion (270c) may be seen on the overall appearance of the safety shoe (10c).

[0187] The coupling member (300) is disposed behind the toe cap (200c) and is coupled to the toe cap (200c) in the forward-rearward direction. Since the safety shoe (10c) according to the fourth embodiment of the present disclosure does not have a concave portion formed in the toe cap (200c) due to the protrusion portion (270c) of the toe cap (200c), a separate convex portion is not formed in the coupling member (300).

[0188] Due to the protrusion portion (270c) of the toe cap (200c), a space for movement of the little toe (LT) of the wearer is secured in the safety shoe (10c). Therefore, the little toe (LT) can be prevented from touching an inner surface of the outer shell (140) or the little toe side wall (240) of the toe cap (200c) and feeling stuffy or pain.

[0189] As described above, since free movement of the little toe (LT) is guaranteed, the wearer can feel a high level of wearing comfort even though the outer shell (140) of the safety shoe (10c) is made of a hard material.

[0190] Additionally, since the protrusion portion (270c) is formed integrally with the toe cap (200c), the position of the protrusion portion (270c) can be easily fixed, making it easy to manufacture the safety shoe (10c).

[0191] Additionally, since the strength of the protrusion portion (270c) is maintained high, the little toe (LT) can be easily protected from external impact.

[0192] The protrusion portion (270c) and the joint potion (273c) may be formed integrally with the toe cap (200c). In this case, the protrusion portion (270c) and the joint portion (273c) may be formed by press processing or the like on the little toe side wall (240) of the toe cap (200c). As described above, when the protrusion portion (270c) and the joint portion (273c) are formed integrally with the toe cap (200c), the toe cap (200c), the protrusion portion (270c), and the joint portion (273c) are made of the same material.

[0193] Unlike the above, the protrusion portion (270c) and the joint portion (273c) may be manufactured separately from the toe cap (200c). In this case, a concave portion is formed at a rear end of the toe cap (200c), and a protrusion portion (270c) and the joint portion (273c) are provided to cover the concave portion. Therefore, a space opened by the concave portion and formed within the protrusion portion (270c) and the joint portion (273c) serves as the internal space (271c). The protrusion portion (270c) and the joint potion (273c) may be bonded to the toe cap (200c) using an adhesive or the like. As described above, when the protrusion portion (270c) and the joint portion (273c) are formed separately from the toe cap (200c), the toe cap (200c), the protrusion portion (270c), and the joint portion (273c) are made of different materials. However, the protrusion portion (270c) and the joint portion (273c) may be made of the same material.

Safety Shoe (10d) According to Fifth Embodiment of the Present Disclosure

[0194] Hereinafter, a safety shoe (10d) according to a fifth embodiment of the present disclosure will be described with reference to FIG. 14.

[0195] FIG. 14 is a view illustrating a state in which a safety shoe according to a fifth embodiment of the present disclosure is worn on a foot of a wearer.

[0196] As illustrated in FIG. 14, the safety shoe (10d) according to the fifth embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10d); an outer shell (140) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer and forming the shape of the safety shoe (10d); a toe cap (200d) provided inside a front toe part of the safety shoe (10d) and located in front of a little toe (LT) of the foot (F); and a protruding member (400) provided on an inner side of the outer shell (140) so as to be disposed at a position corresponding to the little toe (LT) of the foot (F), and protruding convexly outward to form an internal space (411) therewithin for allowing movement of the little toe (LT) within the internal space.

[0197] The safety shoe (10d) according to the fifth embodiment of the present disclosure remains the same as the safety shoe (10d) according to the first embodiment of the present disclosure described above, except that the shape of the toe cap (200d) is different. Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0198] The toe cap (200d) may include: a front wall (210) forming a front surface of the toe cap (200d); an upper wall (220) forming an upper surface of the toe cap (200d); a big toe side wall (230) forming a big toe side surface of the toe cap (200d); a little toe side wall (240) forming a little toe side surface of the toe cap (200); and a bent portion (250) formed by bending and extending from a lower part of each of the front wall (210), the big toe side wall (230), and the little toe side wall (240), and forming a part of a bottom surface of the toe cap (200).

[0199] The safety shoe (10d) according to the fifth embodiment does not have a separate concave portion in the toe cap (200d).

[0200] The little toe side wall (240) of the toe cap (200d) has a rear end located further forward than the little toe (LT). Therefore, the toe cap (200d) has a shape that covers only a part of the toes of the foot (F).

[0201] The little toe side wall (240) of the toe cap (200d) is located on an inner side of the protruding member (400).

[0202] The little toe (LT) is allowed to be moved outward within the internal space (411) of the protrusion portion (410). That is, since the space is secured by the internal space (411), free movement of the little toe (LT) can be guaranteed.

[0203] Since the rear end of the little toe side wall (240) of the toe cap (200d) is located further forward than the little toe (LT), the little toe (LT) moving within the internal space (411) can be prevented from being hindered in its movement by the little toe side wall (240).

[0204] As described above, according to the safety shoe (10d) according to the fifth embodiment of the present disclosure, by forming the toe cap (200d) so as not to cover the little toe (LT) and by forming the protruding member (400) to provide the space for movement of the little toe (LT), the wearer can be prevented from feeling discomfort in the toes without increasing the size or weight of the safety shoe (10d), thereby ensuring a high level of wearing comfort.

Safety Shoe (10e) According to Sixth Embodiment of the Present Disclosure

[0205] Hereinafter, a safety shoe (10e) according to a sixth embodiment of the present disclosure will be described with reference to FIGS. 15 to 16.

[0206] FIG. 15 is an enlarged perspective view illustrating a front toe part of a safety shoe according to a sixth embodiment of the present disclosure. FIG. 16 is a perspective view illustrating a state in which an outer shell is removed from the safety shoe according to the sixth embodiment of the present disclosure.

[0207] As illustrated in FIGS. 15 and 16, the safety shoe (10e) according to the sixth embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10e); an outer shell (140e) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer, forming the shape of the safety shoe (10e), and having a protrusion portion (141e) disposed at a position corresponding to a little toe (LT) of the foot (F) and protruding convexly outward to form an internal space (143e) therewithin for allowing movement of the little toe (LT) within the internal space.

[0208] The safety shoe (10e) according to the sixth embodiment of the present disclosure remains the same as the safety shoe (10e) according to the first embodiment of the present disclosure, except that the protrusion portion (141e) is formed integrally with the outer shell (140e). Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0209] The outer shell (140e) may include the protrusion portion (141e) having the internal space (143e) therewithin and formed convexly outward, and a joint portion (142e) formed by a region where the protrusion portion (141e) and the outer shell (140e) are connected to each other.

[0210] The protrusion portion (141e) is formed convexly outward from the outer shell (140e) so that the internal space (143e) is formed within the protrusion portion. In this case, it is preferable that a protruding length of the protrusion portion (141e) is in the range of 2 mm to 4 mm.

[0211] The protrusion portion (141e) may have an overall pentagonal shape. In this case, it is preferable that a rear part of the protrusion portion (141e) is formed to have the longest side among five sides of the pentagonal shaped protrusion portion (141e).

[0212] The internal space (143e) is formed within an inner surface of the protrusion portion (141e), so an inner surface of the outer shell (140e) is located further inward than the inner surface of the protrusion portion (141e).

[0213] The internal space (143e) is a space defined from the inner surface of the outer shell (140e) to the inner surface of the protrusion portion (141e).

[0214] The joint portion (142e) is formed by a region where the protrusion portion (141e) and the outer shell (140e) are connected to each other.

[0215] When the protrusion portion (141e) has a pentagonal shape, the joint portion (142e) may be composed of five surfaces to correspond to the pentagonal shaped protrusion portion (141e). Therefore, the joint portion (142e) is formed to be entirely closed.

[0216] The boundary lines of the surfaces of the joint portion (142e) are connected to vertices of the protrusion portion (141e). Therefore, when the protrusion portion (141e) has a pentagonal shape, five vertices are connected to the boundary lines of the five surfaces.

[0217] The protrusion portion (400) is located on an outer side of a concave portion (260) of a toe cap (200). In detail, the protrusion portion (141e) is located at a position corresponding to the concave portion (260) of the toe cap (200). Therefore, the concave portion (260) is located on an inner side of the internal space (143e) of the protrusion portion (141e).

[0218] The protrusion portion (141e) and the joint portion (142e) may be formed on the outer shell (140e) by thermal processing, press processing, or the like.

[0219] As described above, when the outer shell (140e) is provided with the protrusion portion (141e) and the joint portion (142e), a separate protruding member is not required. Accordingly, the manufacturing process can be simple, and the protruding member can be prevented from moving and causing the position of the protrusion portion (141e) to become distorted.

Safety Shoe (10f) According to Seventh Embodiment of the Present Disclosure

[0220] Hereinafter, a safety shoe (10f) according to a seventh embodiment of the present disclosure will be described with reference to FIG. 17.

[0221] FIG. 17 is a perspective view illustrating a state in which an outer shell is removed from a safety shoe according to a seventh embodiment of the present disclosure.

[0222] As illustrated in FIG. 17, the safety shoe (10f) according to the seventh embodiment of the present disclosure may include: an insole (110) on which a foot (F) of a wearer rests; a midsole (120) provided under the insole (110); an outsole (130) provided under the insole (110) and the midsole (120) to form a bottom of the safety shoe (10f); an outer shell (140) provided on the midsole (120) and the outsole (130) to cover the foot (F) of the wearer and forming the shape of the safety shoe (10f); a toe cap (200) having a concave portion (260) formed concavely in the forward direction at a position corresponding to a little toe (LT) of the foot (F); a protruding member (400) provided on an inner side of the outer shell (140) so as to be disposed at a position corresponding to the little toe (LT) of the foot (F), and protruding convexly outward to form an internal space (411) therewithin for allowing movement of the little toe (LT) within the internal space; a coupling member (300ff) provided inside a front toe part of the safety shoe (10f), and disposed behind the toe cap (200) to be coupled to the toe cap (200).

[0223] The safety shoe (10f) according to the seventh embodiment of the present disclosure remains the same as the safety shoe (10) according to the first embodiment of the present disclosure described above, except that the shape of the coupling member (300ff) is different. Therefore, the description of the same configuration can be replaced with that of the safety shoe (10) according to the first embodiment of the present disclosure described above, and any duplicate description will be omitted.

[0224] The coupling member (300f) is disposed behind the toe cap (200) and is coupled to the toe cap (200) in the forward-rearward direction.

[0225] The coupling member (300f) may be made of a soft material. Therefore, the coupling member (300f) functions to prevent the instep of the wearer from touching a rear part of an upper wall (220) of the toe cap (200) and feeling pain.

[0226] The coupling member (300f) is configured so that a side of the coupling member (300f) corresponding to the little toe (LT) is formed short so that the coupling member (300f) is not located in the concave portion (260). That is, the coupling member (300f) is not provided with a little toe side surface corresponding to the little toe (LT). Therefore, the concave portion (260) remains as an empty space.

[0227] As described above, since the coupling member (300f) does not have a portion corresponding to the concave portion (260), only the concave portion (260) is located in the internal space (411) of a protrusion portion (410).

[0228] By forming the coupling member (300f) so as not to be located in the concave portion (260), the degree of freedom of the little toe (LT) can be guaranteed through the space of the concave portion (260).

[0229] The coupling member (300f) may also be applied to the safety shoes (10a) to (10e) according to the second to sixth embodiments described above.

[0230] Although the preferred embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions, and substitutions are possible, without departing from the scope and spirit of the present disclosure as disclosed in the accompanying claims.
