Description

Technical Field

[0001] The present invention relates to safety shoes worn on the feet of a wearer.

Background Art

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

[0003] Generally, safety shoes refer to footwear used for foot protection to protect the feet from falling objects that fall on the feet in factories, construction sites, etc., or to prevent the toes from hitting very sharp or hard objects during walking and getting injured.

[0004] In particular, safety shoes used at construction sites must have a very thick outer skin in order to prevent heavy objects from falling and hurting the feet or absorbing the impact caused by falling objects, and the thickness is defined by industrial safety regulations.

[0005] Also, in order to protect the feet from sharp or sharp objects that have fallen on the floor, the thickness of the bottom material such as the outsole and midsole must also be thick.

[0006] As a result, in order to safely protect the feet in the overall structure of the safety shoes, the material itself is made of a hard outer skin, and the bottom material must also be made of a soft and highly compressible material in consideration of the thickness and mobility.

[0007] Thus, the safety shoes have no choice but to be very thick, and as a result, the wearing comfort of the wearer is much inferior to that of general shoes.

[0008] In particular, the hard outer skin of the safety shoes may make the wearer feel cramped, and as a result, when the wearer wears them for a long time, problems such as foot discomfort and pain occur.

Therefore, the left-foot safety shoe can be described as being symmetrical to the safety shoes 10, 10a, 10b, and 10c described later.

[0036] Safety shoe 10 according to the first embodiment of the present invention The safety shoe 10 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 7b.

[0037] Figure 1 is a side view of a safety shoe according to the first embodiment of the present invention; Figure 2 is a perspective view showing an enlarged view of the toe portion of the safety shoe according to the first embodiment of the present invention; Figure 3 is a perspective view showing the safety shoe according to the first embodiment of the present invention with the outer shell removed; Figure 4 is a perspective view showing the position of the protruding member in the safety shoe according to the first embodiment of the present invention; Figures 5a and 5b are perspective views of the toe cap of the safety shoe according to the first embodiment of the present invention; Figure 6 shows the state in which a wearer's foot is wearing the safety shoe according to the first embodiment of the present invention; and Figures 7a and 7b are perspective views of the protruding member of the safety shoe according to the first embodiment of the present invention.

[0038] As shown in Figures 1 to 7b, the safety shoe 10 according to the first embodiment of the present invention is a safety shoe 10 in which the wearer's foot F is worn, and comprises an insole 110 on which the wearer's foot F is placed, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 so as to enclose the wearer's foot F and forming the shape of the safety shoe 10, and the position of the little toe LT of the foot F The safety shoe can be configured to include: a toe cap 200 having a recess 260 formed in a concave shape in the forward direction; a protruding member 400 provided on the inside of the outer shell 140 so as to be positioned corresponding to the little toe LT of the foot F, with a convex shape protruding outward and an internal space 411 formed on the inside that allows the little toe LT to move; and a connecting member 300 provided inside the toe of the safety shoe 10, having a shape corresponding to the recess 260, a convex portion 310 that fits into the recess 260, and positioned behind the toe cap 200 to connect with the toe cap 200.

[0039] The insole 110 is the part where the wearer's foot F rests and the sole of the foot makes contact, and it is located on top of the midsole 120.

[0040] Furthermore, the insole 110 is located above the bent portion 250 of the toe cap 200.

[0041] Below the insole 110, a midsole 120 and an outsole 130 are provided.

[0042] An outsole 130, which forms the bottom of the safety shoe 10, is provided at the bottom of the midsole 120.

[0043] An outer shell 140 is provided on the upper part of the midsole 120 and outsole 130 to enclose the wearer's foot F.

[0044] The outer shell 140 encloses the wearer's foot F and the outer surface of the toe cap 200, forming the outer surface and shape of the safety shoe 10.

[0045] To protect the wearer's feet F from falling objects and sharp objects, the outer shell 140 may be made of a hard material.

[0046] As described above, the safety shoe 10 has a multi-layered outsole structure in which the outsole 130 forms the bottom of the safety shoe 10, by comprising a midsole 120 and an outsole 130 provided below the midsole 120.

[0047] In contrast, the safety shoe 10 can have a single-layer sole structure in which the midsole 120 or outsole 130 forms the bottom of the safety shoe 10, by having only a midsole 120 or outsole 130.

[0048] As shown in Figures 3 to 5b, the toe cap 200 is provided inside the toe of the safety shoe 10 and can be configured to include a front wall 210 that forms the front surface of the toe cap 200, an upper wall 220 that forms the top surface of the toe cap 200, a thumb side wall 230 that forms the thumb side of the toe cap 200, a little finger side wall 240 that forms the little finger side of the toe cap 200, a bent portion 250 that is formed to be bent and extend from the lower parts of the front wall 210, the thumb side wall 230 and the little finger side wall 240 and forms part of the bottom surface of the toe cap 200, and a recess 260 that is formed in a concave shape from the rear end of the little finger side wall 240 toward the front of the toe cap 200 and opens at least a part of the rear end of the little finger side wall 240.

[0049] The toe cap 200 has a front wall 210, an upper wall 220, a thumb side wall 230, and a little finger side wall 240, which make up the front, top, and both sides of the toe cap 200, respectively. A bent portion 250 is formed to be folded and extend from the lower part of the front wall 210, the thumb side wall 230, and the little finger side wall 240, forming part of the bottom surface of the toe cap. The rear end of the little finger side wall 240 may be provided with a recess 260 which is formed in a concave shape from the rear end of the little finger side wall 240 toward the front of the toe cap 200, and which opens up at least a part of the rear end of the little finger side wall 240.

[0050] As described above, the toe cap 200 has a shape in which a part of the bottom surface is open, and the front, top and both sides are closed by the front wall 210, top wall 220, thumb side wall 230, and little finger side wall 240. However, in this case, a part of the little finger side wall 240 is open by the recess 260, so the area on the side of the little finger side wall 240 where the recess 260 is formed is not closed, but is open.

[0051] The front wall 210, upper wall 220, thumb side wall 230, and little finger side wall 240 are formed integrally so as to extend from one another, and each of the front wall 210, upper wall 220, thumb side wall 230, and little finger side wall 240 is treated as a curved surface, and the overall shape is streamlined, becoming narrower towards the front of the toe cap 200.

[0052] The bent portion 250 is formed to extend by being folded at the lower part of the front wall 210, the thumb side wall 230, and the little finger side wall 240, respectively.

[0053] The bent portion 250 forms only a part of the bottom surface of the toe cap 200. As shown in Figures 5a and 5b, the bent portion 250 as a whole is "U" shaped. Therefore, the bottom surface of the toe cap 200 has a shape with the inside of the "U" shape open.

[0054] The bent portion 250 is bent towards the bottom surface of the toe cap 200 such that the angle between the inner surfaces of the front wall 210, thumb side wall 230, and little finger side wall 240 and the upper surface of the bent portion 250 is 90° or more. In this case, the width of the bent portion 250 is several millimeters to several tens of millimeters in length.

[0055] The toe cap 200 is made of a hard material such as metal, which protects the foot F from falling objects.

[0056] If the safety shoe 10 is equipped with a toe cap 200, the insole 110 is located on the upper part of the bent portion 250.

[0057] The front wall 210 forms the front surface of the toe cap 200 and has a shape that narrows towards the front. In this case, the front wall 210 has a curved shape, which gives the front wall 210 a streamlined shape.

[0058] 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.

[0059] The upper wall 220 serves to protect the wearer's toes from falling objects by covering the upper part of the wearer's toes.

[0060] The thumb-side wall 230 extends from the thumb-side posterior end of the front wall 210 and forms the side of the toe cap 200. As shown in Figures 1 to 5b, when the safety shoe 10 is a right-foot safety shoe 10, the thumb-side wall 230 of the toe cap 200 forms the left side of the toe cap 200.

[0061] The thumb side wall 230 has a shape that slopes toward the thumb as it moves towards the rear. In this case, the thumb side wall 230 has a curved shape, which gives it a streamlined shape.

[0062] The little toe side wall 240 extends from the little toe side posterior end of the anterior wall 210 and forms the side of the toe cap 200. If the safety shoe 10 is a right-foot safety shoe 10, the little toe side wall 240 of the toe cap 200 forms the right side of the toe cap 200.

[0063] A recess 260 is provided on the side wall 240 of the little finger.

[0064] The recess 260 is formed in a concave shape extending forward from the rear end of the little finger side wall 240 toward the toe cap 200. Thus, the recess 260 opens up at least a portion of the rear end of the little finger side wall 240.

[0065] As shown in Figure 6, such recesses 260 serve to prevent the little toe LT from coming into contact with the little toe side wall 240 of the toe cap 200 when the wearer is wearing the safety shoes 10.

[0066] In other words, the recess 260 is formed in a position corresponding to where the little toe LT is located when the wearer puts on the safety shoe 10 with the toe cap 200, thereby serving to prevent the little toe LT from coming into contact with the little toe side wall 240 of the toe cap 200.

[0067] The recess 260 is formed on the upper part of the bent portion 250.

[0068] The recess 260 is formed at a position separated upward from the bent portion 250, thereby creating a separation portion 241 between the recess 260 and the bent portion 250.

[0069] The separation portion 241 refers to a part of the little finger side wall 240 that connects the bent portion 250 and the recess 260 at the lower part of the recess 260.

[0070] In other words, the recess 260 is formed at a position separated upward from the bent portion 250, so that a separation portion 241 is formed between the recess 260 and the bent portion 250, and the separation portion 241 is a part of the little finger side wall 240 that connects the bent portion 250 and the recess 260 at the lower part of the recess 260.

[0071] As described above, by forming a separation portion 241 between the recess 260 and the bent portion 250, the curved shape of the recess 260 can be easily formed.

[0072] Furthermore, the formation of the separation portion 241 further maximizes the function of the recess 260 in mitigating external impacts applied to the toe cap 200.

[0073] Due to the configuration of the recess 260 described above, the thumb side wall 230 and the little finger side wall 240 of the toe cap 200 have different shapes from each other. In other words, the thumb side wall 230 and the little finger side wall 240 of the toe cap 200 have asymmetrical shapes from each other.

[0074] The protruding member 400 is provided on the outside of the toe cap 200 and on the inside of the outer skin 140 so as to be positioned at a location corresponding to the little toe LT of the foot F. In other words, the protruding member 400 is interposed between the toe cap 200 and the outer skin 140.

[0075] The protruding member 400 can be configured to include a protruding portion 410 formed in a convex shape on the outside with an internal space 411 formed on the inside, a frame portion 420 provided along the periphery of the protruding portion 410, and a joint 430 consisting of a region to which the protruding portion 410 and the frame portion 420 are connected.

[0076] The protruding portion 410 is formed in a convex shape outward with respect to the frame portion 420, such that an internal space 411 is formed on the inside.

[0077] Specifically, the protruding portion 410 is formed on the outer skin 140 at the position corresponding to the little finger LT, so as to protrude outward in a convex shape with respect to the frame portion 420. In this case, the protruding length of the protruding portion 410 is preferably 2 mm or more and 4 mm or less.

[0078] The projection 410 can have a pentagonal shape overall. In this case, it is preferable that the rear of the projection 410 is formed to have the longest side among the five sides of the pentagon of the projection 410.

[0079] The frame portion 420 is provided along the periphery of the protruding portion 410.

[0080] The frame portion 420 has a flat shape, and the protruding portion 410 protrudes outward relative to the frame portion 420.

[0081] The outer surface of the frame portion 420 is located inward from the outer surface of the protruding portion 410.

[0082] An internal space 411 is formed inside the inner surface of the protruding portion 410, so that the inner surface of the frame portion 420 is located inside the inner surface of the protruding portion 410.

[0083] The internal space 411 is the space from the inner surface of the frame portion 420 to the inner surface of the protruding portion 410.

[0084] When the inner surface of the frame portion 420 contacts the outer surface of the toe cap 200, the protruding portion 410 of the protruding member 400 is in a position corresponding to the recess 260 of the toe cap 200, so that the protruding member 400 can be supported via the frame portion 420.

[0085] The joint 430 consists of a region where the protruding portion 410 and the frame portion 420 are connected.

[0086] If the projection 410 has a pentagonal shape, the joint 430 may have five faces corresponding to the pentagonal shape of the projection 410. Thus, the joint 430 is formed to be completely closed.

[0087] The boundary lines of the joint 430 are connected to the vertices of the projection 410. Therefore, if the projection 410 has a pentagonal shape, the five vertices are connected to the boundary lines of the five faces.

[0088] The protruding member 400 is located outside the recess 260 of the toe cap 200. More specifically, as shown in Figure 6, the protrusion 410 of the protruding member 400 is located in a position corresponding to the recess 260 of the toe cap 200. Therefore, the recess 260 is located inside the internal space 411 of the protruding portion 410.

[0089] The protruding member 400 causes the outer shell 140 to protrude outward in a convex shape. Therefore, the shape of the protruding member 400 can be seen from the overall appearance of the safety shoe 10.

[0090] The toe cap 200, the protruding member 400, and the outer skin 140 can be joined together by heat pressing or the like to form a single unit. As a result, the position of the protruding member 400 is fixed, and the internal space 411 of the protruding portion 410 can be continuously positioned outside the recess 260, thereby ensuring a space that guarantees the movement of the little toe LT.

[0091] The connecting member 300 is positioned behind the toe cap 200 and connects to the toe cap 200 in the front-to-back direction.

[0092] A protrusion 310 is provided on one side of the connecting member 300.

[0093] The protrusion 310 has a shape corresponding to the recess 260.

[0094] The protrusion 310 is provided on the little finger side of the connecting member 300, at a position corresponding to the recess 260.

[0095] With the convex portion 310 fitted into the concave portion 260, the connecting member 300 and the toe cap 200 are connected in the front-rear direction.

[0096] The connecting member 300 is made of a soft material. Therefore, the connecting member 300 serves to prevent the wearer's instep from coming into contact with the rear of the upper wall 220 of the toe cap 200 and causing pain.

[0097] When the convex portion 310 and the concave portion 260 are joined by the connecting member 300, the internal space 411 of the protruding portion 410 is located on the outside of the convex portion 310.

[0098] In the safety shoe 10 according to the first embodiment of the present invention described above, a recess 260, a protrusion 310, and a projection 410 are located at a position corresponding to the little toe LT.

[0099] These recesses 260, protrusions 310, and projections 410 provide space for the wearer's little toe LT to move. Therefore, the wearer can prevent their little toe LT from coming into contact with the inner surface of the outer skin 140 or the little toe side wall 240 of the toe cap 200, which could cause discomfort or pain.

[0100] Specifically, with conventional safety shoes, there was a problem where the wearer's toes would touch the inside of the outer sole or toe cap, causing discomfort. In particular, with safety shoes equipped with a toe cap, if the toe cap is made larger to solve this problem, the safety shoe becomes larger and heavier, resulting in a poor fit.

[0101] To solve these problems, in the present invention, a protrusion 410 with an internal space 411 formed on the inside is separately provided inside the safety shoe 10, and a space is secured that allows the little toe LT to move outward. This makes it possible to secure space without making the safety shoe 10 or toe cap 200 larger, and to improve the comfort of wearing the safety shoe 10 while maintaining a good fit.

[0102] Furthermore, since the connecting member 300 and the protrusion 310 are made of a soft material, the degree of freedom of the little finger LT is guaranteed even with the protrusion 310. In other words, because the protrusion 310 is made of a soft material, when the little finger LT moves outward, the protrusion 310 also moves outward within the internal space 411, thereby guaranteeing the free movement of the little finger LT.

[0103] As described above, because the free movement of the little toe (LT) is guaranteed, the wearer can experience good comfort even though the outer shell 140 of the safety shoe 10 is made of a hard material.

[0104] The safety shoe 10 according to the first embodiment of the present invention described above can achieve space for the little toe LT via the protruding member 400, even if it does not have a toe cap 200.

[0105] Safety shoe 10a according to a second embodiment of the present invention The safety shoe 10a according to the second embodiment of the present invention will be described below with reference to Figure 8.

[0106] Figure 8 is a perspective view showing a safety shoe according to a second embodiment of the present invention with the outer shell removed.

[0107] As shown in Figure 8, the safety shoe 10a according to the second embodiment of the present invention comprises an insole 110 on which the wearer's foot F rests, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10a, an outer shell 140 provided above the midsole 120 and outsole 130 to enclose the wearer's foot F and forming the shape of the safety shoe 10a, and a toe cap having a recess 260 formed in a forward-facing concave shape at the position of the little toe LT of the foot F. The shoe can be configured to include a toe cap 200, a protruding member 400 provided on the inside of the outer shell 140 so as to be positioned corresponding to the little toe LT of the foot F, with a convex protrusion outward and an internal space 411 formed on the inside that allows the little toe LT to move, a connecting member 300 provided inside the toe of the safety shoe 10a, having a shape corresponding to the recess 260, having a protrusion 310 that fits into the recess 260, and being positioned behind the toe cap 200 and connected to the toe cap 200, and a soft member 470 provided on the inside of the protrusion 410 of the protruding member 400.

[0108] The safety shoe 10a according to the second embodiment of the present invention has the same configuration as the safety shoe 10 according to the first embodiment of the present invention described above, except that it additionally includes a soft member 470. Therefore, the description of the same configuration can be replaced with the description of the safety shoe 10 according to the first embodiment of the present invention described above, and redundant descriptions will be omitted.

[0109] The soft member 470 is provided inside the protruding portion 410 of the protruding member 400.

[0110] Specifically, the flexible member 470 may be provided in the internal space 411 formed inside the protruding portion 410. In this case, the flexible member 470 may be provided so as to fill at least a portion of the internal space 411.

[0111] The flexible member 470 may be made of a soft, flexible, and elastic material. For example, the flexible member 470 may be made of sponge, EVA, or the like.

[0112] The aforementioned soft member 470 is provided inside the internal space 411 and serves to improve comfort by preventing the little toe LT from directly contacting the inside of the protruding portion 410.

[0113] In other words, since the little toe LT is in direct contact with the soft, fluffy material 470, the wearer can experience a better fit than when the little toe LT is in direct contact with the inside of the relatively hard protruding part 410 of the protruding material 400.

[0114] Such a flexible member 470 can be provided by being bonded to the inside of the protruding portion 410 of the protruding member 400 with an adhesive or the like.

[0115] The soft member 470 can also be applied to the internal spaces 411, 411b, 271c, and 143e of the safety shoe 10 according to the first embodiment of the present invention described above, and to the internal spaces 411, 411b, 271c, and 143e of the safety shoes 10b to 10e according to the third to sixth embodiments described later.

[0116] Safety shoe 10b according to the third embodiment of the present invention The safety shoe 10b according to the third embodiment of the present invention will be described below with reference to Figures 9 to 11b.

[0117] Figure 9 is a perspective view showing an enlarged view of the toe portion of a safety shoe according to the third embodiment of the present invention, Figure 10 is a perspective view showing the position of the protruding member in the safety shoe according to the third embodiment of the present invention, and Figures 11a and 11b are perspective views of the protruding member of the safety shoe according to the third embodiment of the present invention.

[0118] As shown in Figures 9 to 11b, the safety shoe 10b according to the third embodiment of the present invention comprises an insole 110 on which the wearer's foot F rests, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10b, an outer shell 140 provided above the midsole 120 and outsole 130 to enclose the wearer's foot F and forming the shape of the safety shoe 10b, a toe cap 200 having a recess 260 formed in a forward-facing concave shape at the position of the little toe LT of the foot F, and an internal space 411 provided on the inside of the outer shell 140 so as to be positioned corresponding to the little toe LT of the foot F, protruding outward in a convex shape and allowing the little toe LT to move inward. b The structure can include a formed protruding member 400b and a connecting member 300 provided inside the toe of the safety shoe 10b, having a shape corresponding to the recess 260 and a protrusion 310 that fits into the recess 260, and positioned behind the toe cap 200 to connect with the toe cap 200.

[0119] In the safety shoe 10b according to the third embodiment of the present invention, the shape of the protruding member 400b differs from that of the protruding member 400 of the safety shoe 10 according to the first embodiment of the present invention, but the remaining components are the same. Therefore, the description of the same components can be replaced with the description of the safety shoe 10 according to the first embodiment of the present invention described above, and redundant explanations will be omitted.

[0120] The protruding member 400b is provided on the outside of the toe cap 200 and on the inside of the outer skin 140 so as to be positioned corresponding to the little toe LT of the foot F. In other words, the protruding member 400b is interposed between the toe cap 200 and the outer skin 140.

[0121] The protruding member 400b can be configured to include a protruding portion 410b formed in a convex shape on the outside with an internal space 411b formed on the inside, a frame portion 420b provided along the periphery of the protruding portion 410b, and a joint 430b consisting of a region to which the protruding portion 410b and the frame portion 420b are connected.

[0122] The protruding portion 410b is formed in a convex shape outward with respect to the frame portion 420b, such that an internal space 411b is formed on the inside.

[0123] The protruding portion 410b is formed on the outer skin 140 at the position corresponding to the little finger LT, so as to protrude outward in a convex shape with respect to the frame portion 420b. In this case, the protruding length of the protruding portion 410b is preferably 2 mm or more and 4 mm or less.

[0124] The protruding portion 410b may have a pentagonal shape overall.

[0125] The frame portion 420b is provided along at least a part of the periphery of the protruding portion 410b.

[0126] As an example, the frame portion 420b is provided along the front, top, and bottom, excluding the rear of the protruding portion 410b. That is, the frame portion 420b is provided along the periphery, excluding the rear of the protruding portion 410b.

[0127] The frame portion 420b has a flat shape, and the protruding portion 410b protrudes outward with respect to the frame portion 420b.

[0128] The outer surface of the frame portion 420b is located inward from the outer surface of the protruding portion 410b.

[0129] An internal space 411b is formed inside the inner surface of the protruding portion 410b, and as a result, the inner surface of the frame portion 420b is located inside the inner surface of the protruding portion 410b.

[0130] The internal space 411b is the space from the inner surface of the frame portion 420b to the inner surface of the protruding portion 410b.

[0131] When the inner surface of the frame portion 420b contacts the outer surface of the toe cap 200, the protruding member 400b can be supported via the frame portion 420b when the protruding portion 410b of the protruding member 400b is in a position corresponding to the recess 260 of the toe cap 200.

[0132] The joint 430b consists of a region where the protruding portion 410b and the frame portion 420b are connected.

[0133] The joint 430b is formed so that the rear of the joint 430b is open.

[0134] The joint 430b can be formed such that the area excluding the area behind the joint 430b is closed.

[0135] When the projection 410b has a pentagonal shape, the frame portion 420b is provided along the periphery except for the rear of the projection 410b, so the rear of the joint 430b is also open. Therefore, the joint 430b is not formed in the area corresponding to the rear of the projection 410b. As a result, the joint 430b consists of the remaining four surfaces excluding the surface corresponding to the rear of the projection 410b.

[0136] Due to the shapes of the protruding portion 410b, the frame portion 420b, and the joint 430b described above, the internal space 411b of the protruding portion 410b has a shape in which the inside and rear are open, and the front, top, bottom, and outside are closed.

[0137] The boundary lines of the four faces of the joint 430b are connected to the vertices of the projection 410b. Therefore, if the projection 410b has a pentagonal shape, the five vertices are connected to the boundary lines of the four faces.

[0138] The protruding member 400b is located outside the recess 260 of the toe cap 200. The protruding portion 410b of the protruding member 400b is located in a position corresponding to the recess 260 of the toe cap 200. Therefore, the recess 260 is located inside the internal space 411b of the protruding portion 410b.

[0139] The protruding member 400b causes the outer shell 140 to protrude outward in a convex shape. Therefore, the safety shoe 10 b The shape of the protruding member 400b can be seen from the overall appearance.

[0140] The toe cap 200, the protruding member 400b, and the outer shell 140 can be joined together by heat pressing or the like to form a single unit. As a result, the position of the protruding member 400b is fixed, and the internal space 411b of the protruding portion 410b can be continuously positioned outside the recess 260, thereby ensuring a space that guarantees the movement of the little toe LT.

[0141] As described above, the protruding member 400b of the safety shoe 10b according to the third embodiment of the present invention has a shape in which the rear of the joint 430b is open. Therefore, when the wearer puts on the safety shoe 10b, it is possible to prevent the little toe LT from getting caught by the rear of the joint 430b.

[0142] In other words, the safety shoe 10b according to the third embodiment of the present invention eliminates the surface formed at the rear of the protruding member 400b, thereby preventing the little toe LT from getting caught on the surface formed at the rear of the protruding member 400b when wearing the safety shoe 10b, and thus ensuring a good fit for the safety shoe 10b.

[0143] The protruding member 400b with an open rear end, as described above for the third embodiment of the present invention, can also be applied to the safety shoe 10d according to the fifth embodiment and the safety shoe 10e according to the sixth embodiment, which will be described later.

[0144] In detail, as in the safety shoe 10d according to the fifth embodiment described later, the toe cap 200d does not have a separate recess and the toe cap 200d is located in front of the little toe LT, and the protruding member 400b with an open rear can also be applied.

[0145] Furthermore, even when a protrusion 141e is formed on the inside of the outer shell 140, as in the safety shoe 10e according to the sixth embodiment, the joint 142e can have a configuration in which the rear is open, that is, the rear of the joint 142e is open, and the front, top, and bottom are closed except for the rear.

[0146] Safety shoe 10c according to the fourth embodiment of the present invention The safety shoe 10c according to the fourth embodiment of the present invention will be described below with reference to Figures 12 to 13c.

[0147] Figure 12 is a perspective view showing the outer shell removed from a safety shoe according to the fourth embodiment of the present invention, Figures 13a and 13b are perspective views of the toe cap of a safety shoe according to the fourth embodiment of the present invention, and Figure 13c is a plan view of the toe cap of a safety shoe according to the fourth embodiment of the present invention.

[0148] Figures 12-13c As shown, the safety shoe 10c according to the fourth embodiment of the present invention comprises an insole 110 on which the wearer's foot F rests, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10c, a toe cap 200c provided inside the toe of the safety shoe 10c and having a projection 270c that protrudes outward in a convex shape at the position of the little toe LT of the foot F and has an internal space 271c formed on the inside that allows the little toe LT to move, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 that encloses the toe cap 200c and encloses the wearer's foot F and forms the shape of the safety shoe 10c, and the safety shoe 10 c The shoe can be configured to include a connecting member 300, which is provided inside the toe of the shoe and positioned behind the toe cap 200c, and is connected to the toe cap 200c.

[0149] In the safety shoe 10c according to the fourth embodiment of the present invention, the protruding portion 270c is integrally formed with the toe cap 200c, and the shape of the toe cap 200c and the shape of the connecting member 300 differ from the safety shoe 10 according to the first embodiment of the present invention described above, while the remaining components are the same. Therefore, the description of the same components can be replaced with the description of the safety shoe 10 according to the first embodiment of the present invention described above, and redundant descriptions will be omitted.

[0150] The toe cap 200c is provided inside the toe of the safety shoe 10c and can be configured to include a front wall 210 that forms the front of the toe cap 200c, an upper wall 220 that forms the top surface of the toe cap 200c, a thumb side wall 230 that forms the big toe side of the toe cap 200c, a little toe side wall 240 that forms the little toe side of the toe cap 200c, a bent portion 250 that is formed to be bent and extend from the lower parts of the front wall 210, the thumb side wall 230, and the little toe side wall 240 and forms part of the bottom surface of the toe cap 200c, and a protruding portion 270c that is formed to protrude outward in a convex shape from the rear end of the little toe side wall 240.

[0151] The toe cap 200c has a front wall of 210, a top wall of 220, a thumb side wall of 230, and a little finger side wall of 240, all of which are the same size as the toe cap 200. c The bent portions 250, which form the front, top, and both sides of the toe cap, are formed to extend from the lower parts of the front wall 210, thumb side wall 230, and little finger side wall 240, respectively, and are formed to form part of the bottom surface of the toe cap.

[0152] The protrusion 270c is formed to bulge outward from the rear end of the little finger side wall 240 and recess inward, corresponding to the position of the little finger LT.

[0153] The protruding portion 270c is formed in a convex shape outward with respect to the little finger side wall 240, such that an internal space 271c is formed on the inside.

[0154] Specifically, the protrusion 270c is formed on the outer skin 140 at the position corresponding to the little finger LT, so as to protrude outward in a convex shape with respect to the little finger side wall 240. In this case, the protruding length of the protrusion 270c is preferably 2 mm or more and 4 mm or less.

[0155] The protruding portion 270c has a rectangular shape overall.

[0156] An internal space 271c is formed on the inner side of the inner surface of the protrusion 270c, so that the inner surface of the little finger side wall 240 is located inward from the inner surface of the protrusion 270c.

[0157] The internal space 271c is the space from the inner surface of the little finger side wall 240 to the inner surface of the protrusion 270c.

[0158] The joint 273c consists of a region where the protruding portion 270c and the little finger side wall 240 are connected.

[0159] The joint 273c is formed so that the rear of the joint 273c is open.

[0160] The joint 273c can be formed such that the area excluding the area behind the joint 273c is closed.

[0161] Since the projection 270c has a rectangular shape and the rear of the joint 273c is open, the joint 273c is not formed in the region corresponding to the rear of the projection 270c. As a result, the joint 273c consists of the remaining three surfaces, excluding the surface corresponding to the rear of the projection 270c.

[0162] The boundary lines of the three faces of the joint 273c are connected to the vertices of the projection 270c. Therefore, if the projection 270c has a quadrilateral shape, the four vertices are connected to the boundary lines of the three faces.

[0163] Due to the shapes of the protrusion 270c, the little finger side wall 240, and the joint 273c described above, the internal space 271c of the protrusion 270c has a shape in which the inside and rear are open, and the front, top, bottom, and outside are closed.

[0164] The protrusion 270c of the toe cap 200c causes the outer shell 140 to also protrude outward in a convex shape. Therefore, the shape of the protrusion 270c is visible from the overall appearance of the safety shoe 10c.

[0165] The connecting member 300 is positioned behind the toe cap 200c and connects to the toe cap 200c in the front-to-back direction. In the safety shoe 10c according to the fourth embodiment of the present invention, since no recess is formed in the toe cap 200c, no separate protrusion is formed on the connecting member 300.

[0166] The protruding portion 270c of the aforementioned toe cap 200c ensures that the safety shoe 10c has space for the wearer's little toe LT to move. Therefore, the wearer can prevent their little toe LT from coming into contact with the inner surface of the outer leather 140 or the little toe side wall 240 of the toe cap 200c, which can cause discomfort or pain.

[0167] As described above, because the free movement of the little toe (LT) is guaranteed, the wearer can experience good comfort even though the outer shell 140 of the safety shoe 10c is made of a hard material.

[0168] Furthermore, since the protrusion 270c is integrally formed with the toe cap 200c, the position of the protrusion 270c can be easily fixed, making it easy to manufacture the safety shoe 10c.

[0169] Furthermore, since the strength of the protruding portion 270c is maintained at a high level, the little finger LT can be easily protected from external impacts.

[0170] The protrusion 270c and joint 273c can be formed integrally with the toe cap 200c. In this case, the protrusion 270c and joint 273c can be formed by applying a process such as pressing to the little finger side wall 240 of the toe cap 200c. When the protrusion 270c and joint 273c are formed integrally with the toe cap 200c in this way, the toe cap 200c, the protrusion 270c, and the joint 273c are made of the same material.

[0171] Contrary to the above, the projection 270c and the joint 273c may be manufactured separately from the toe cap 200c. In this case, a recess is formed at the rear end of the toe cap 200c, and the projection 270c and the joint 273c are provided so as to enclose the recess. Thus, the space formed inside the projection 270c and the joint 273c, which is open due to the recess, becomes the internal space 271c. The projection 270c and the joint 273c can be joined to the toe cap 200c by adhesive or the like. In this way, when the projection 270c and the joint 273c are formed separately from the toe cap 200c, the toe cap 200c, the projection 270c, and the joint 273c are made of different materials. However, the projection 270c and the joint 273c may be made of the same material.

[0172] Safety shoe 10d according to the fifth embodiment of the present invention The safety shoe 10d according to the fifth embodiment of the present invention will be described below with reference to Figure 14.

[0173] Figure 14 shows the state in which the wearer's feet are fitted into safety shoes according to the fifth embodiment of the present invention.

[0174] As shown in Figure 14, the safety shoe 10d according to the fifth embodiment of the present invention can be configured to include an insole 110 on which the wearer's foot F rests, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10d, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 so as to enclose the wearer's foot F and forming the shape of the safety shoe 10d, a toe cap 200d provided inside the toe of the safety shoe 10d and positioned in front of the little toe LT of the foot F, and a protruding member 400 provided on the inside of the outer shell 140 so as to be positioned corresponding to the little toe LT of the foot F, which protrudes outward in a convex shape and has an internal space 411 formed on the inside that allows the little toe LT to move.

[0175] The safety shoe 10d according to the fifth embodiment of the present invention is the same as the safety shoe 1 according to the first embodiment of the present invention described above, except that the shape of the toe cap 200d is different. 0 andThey have the same configuration. Therefore, the description of the same configuration can be replaced with the description of the safety shoe 10 according to the first embodiment of the present invention described above, and redundant descriptions will be omitted.

[0176] The toe cap 200d can be configured to include a front wall 210 forming the front surface of the toe cap 200d, an upper wall 220 forming the top surface of the toe cap 200d, a thumb side wall 230 forming the thumb side of the toe cap 200d, a little finger side wall 240 forming the little finger side of the toe cap 200d, and a bent portion 250 formed to extend from the lower parts of the front wall 210, the thumb side wall 230, and the little finger side wall 240, and to form a part of the bottom surface of the toe cap 200.

[0177] In the fifth embodiment, the safety shoe 10d does not have a separate recess provided in the toe cap 200d.

[0178] The toe cap 200d has a posterior end of the little toe side wall 240 positioned forward of the little toe LT. Therefore, the toe cap 200d has a shape that encloses only a portion of the toes of the foot F. The little toe side wall 240 of the toe cap 200d is located inside the protruding member 400.

[0179] The little finger LT is movable outward within the internal space 411 of the protrusion 410. In other words, the internal space 411 ensures space, thus guaranteeing free movement of the little finger LT.

[0180] Since the posterior end of the little finger side wall 240 of the toe cap 200d is located forward of the little finger LT, the little finger LT, which moves within the internal space 411, is not hindered by the little finger side wall 240.

[0181] As described above, the safety shoe 10d according to the fifth embodiment of the present invention ensures a good fit because the toe cap 200d does not enclose the little toe LT, and the protruding member 400 secures space for the little toe LT to move, thereby preventing the wearer from experiencing discomfort in their toes without increasing the size or weight of the safety shoe 10d.

[0182] Safety shoe 10e according to the sixth embodiment of the present invention The safety shoe 10e according to the sixth embodiment of the present invention will be described below with reference to Figures 15 and 16.

[0183] Figure 15 is a magnified view of the toe portion of a safety shoe according to the sixth embodiment of the present invention, and Figure 16 is a perspective view showing the safety shoe according to the sixth embodiment of the present invention with the outer shell removed.

[0184] As shown in Figures 15 and 16, the safety shoe 10e according to the sixth embodiment of the present invention can be configured to include an insole 110 on which the wearer's foot F rests, a midsole 120 provided below the insole 110, an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10e, and an outer shell 140e provided above the midsole 120 and outsole 130 so as to enclose the wearer's foot F, forming the shape of the safety shoe 10e, positioned corresponding to the little toe LT, and having a protruding portion 141e that protrudes outward in a convex shape on the inside, forming an internal space 143e on the inside that allows the little toe LT to move.

[0185] The safety shoe 10e according to the sixth embodiment of the present invention differs only in that the protruding portion 141e is integrally formed with the outer shell 140e, and the remaining components are the same as those of the safety shoe 10e according to the first embodiment of the present invention described above. 0 and They have the same configuration. Therefore, the description of the same configuration can be replaced with the description of the safety shoe 10 according to the first embodiment of the present invention described above, and redundant descriptions will be omitted.

[0186] The outer shell 140e can be configured to include an internal space 143e formed on the inside, a protruding portion 141e formed in a convex shape on the outside, and a joint 142e consisting of a region to which the protruding portion 141e and the outer shell 140e are connected.

[0187] The protruding portion 141e is formed in a convex shape outward with respect to the outer shell 140e, such that an internal space 143e is formed on the inside. In this case, the protruding length of the protruding portion 141e is preferably 2 mm or more and 4 mm or less.

[0188] The projection 141e can have a pentagonal shape overall. In this case, it is preferable that the rear of the projection 141e is formed to have the longest side among the five sides of the pentagon of the projection 141e.

[0189] An internal space 143e is formed on the inner side of the inner surface of the protrusion 141e, so that the inner surface of the outer shell 140e is located inward from the inner surface of the protrusion 141e.

[0190] The internal space 143e is the space from the inner surface of the outer shell 140e to the inner surface of the protruding portion 141e.

[0191] The joint 142e consists of a region where the protruding portion 141e and the outer shell 140e are connected.

[0192] If the projection 141e has a pentagonal shape, the joint 142e may consist of five faces corresponding to the pentagonal shape of the projection 141e. Therefore, the joint 142e is formed to be completely closed.

[0193] The boundary lines of the joint 142e are connected to the vertices of the projection 141e. Therefore, if the projection 141e has a pentagonal shape, the five vertices are connected to the boundary lines of the five faces.

[0194] The protrusion 141e is located outside the recess 260 of the toe cap 200. More specifically, the protrusion 141e is located in a position corresponding to the recess 260 of the toe cap 200. Thus, the recess 260 is located inside the internal space 143e of the protrusion 141e.

[0195] The protruding portion 141e and the joint 142e can be formed on the outer shell 140e by heat processing, press processing, or the like.

[0196] As mentioned above, when the outer shell 140e is provided with a protrusion 141e and a joint 142e, a separate protruding member is not required. Therefore, the manufacturing process is simplified, and it is possible to prevent the protruding member from moving and causing a displacement of the protrusion 141e.

[0197] Safety shoe 10f according to the seventh embodiment of the present invention The safety shoe 10f according to the seventh embodiment of the present invention will be described below with reference to Figure 17.

[0198] Figure 17 is a perspective view showing a safety shoe according to the seventh embodiment of the present invention with the outer shell removed.

[0199] As shown in Figure 17, the safety shoe 10f according to the seventh embodiment of the present invention can be configured to include: an insole 110 on which the wearer's foot F rests; a midsole 120 provided below the insole 110; an outsole 130 provided below the insole 110 and midsole 120 and forming the bottom of the safety shoe 10f; an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 so as to enclose the wearer's foot F and forming the shape of the safety shoe 10f; a toe cap 200 having a recess 260 formed in a forward-facing concave shape at the position of the little toe LT of the foot F; a protruding member 400 provided on the inside of the outer shell 140 so as to be positioned corresponding to the little toe LT of the foot F, protruding outward in a convex shape and having an internal space 411 formed on the inside that allows the little toe LT to move; and a connecting member 300f provided inside the toe of the safety shoe 10f and positioned behind the toe cap 200 and connected to the toe cap 200.

[0200] The safety shoe 10f according to the seventh embodiment of the present invention has the same configuration as the safety shoe 10 according to the first embodiment of the present invention, except that the shape of the connecting member 300f is different. Therefore, the explanation of the same configuration can be replaced with the explanation of the safety shoe 10 according to the first embodiment of the present invention, and redundant explanations will be omitted.

[0201] The connecting member 300f is positioned behind the toe cap 200 and connects to the toe cap 200 in the front-to-back direction.

[0202] The connecting member 300f is made of a soft material. Therefore, the connecting member 300f serves to prevent the wearer's instep from coming into contact with the rear of the upper wall 220 of the toe cap 200 and causing pain.

[0203] The connecting member 300f is formed shorter on the little finger LT side so that it does not sit in the recess 260. In other words, the connecting member 300f does not have a little finger side corresponding to the little finger LT. Therefore, the recess 260 remains empty.

[0204] As described above, since the connecting member 300f does not have a portion corresponding to the recess 260, only the recess 260 is located in the internal space 411 of the protruding portion 410.

[0205] The advantage of the connecting member 300f not being located in the recess 260 is that the degree of freedom of the little finger LT is guaranteed through the space of the recess 260.

[0206] The connecting member 300f can also be applied to the safety shoes 10a to 10e according to the second to sixth embodiments described above.

[0207] As described above, preferred embodiments of the present invention have been explained with reference to the present invention, but a person ordinary in the art can modify or transform the present invention in various ways without departing from the spirit and scope of the invention as described in the following claims.
