Description

[Technical Field]

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

[0002] There are various types of safety shoes used in industrial sites depending on their purpose.

[0003] Generally, safety shoes refer to footwear used to protect the feet from falling objects in factories or construction sites, or to prevent injuries caused by hitting the toes with very sharp or hard objects while walking.

[0004] In particular, safety shoes used on construction sites must have a very thick outer shell to prevent heavy objects from falling on them and to absorb the impact of falling objects, and this thickness is regulated by industrial safety regulations.

[0005] Furthermore, in order to protect the feet from sharp or sharp objects that fall on the floor, the thickness of the sole material such as the outsole and midsole must also be large.

[0006] Therefore, in order to safely protect the feet from the viewpoint of the overall structure of safety shoes, the material itself must be made of a hard outer shell, and the sole must also be made of a soft material with high compressive strength in consideration of thickness and activity.

[0007] As a result, safety shoes have no choice but to be very thick, which makes them much less comfortable for the wearer than regular shoes.

[0008] In particular, the hard outer shell of safety shoes can make the wearer feel uncomfortable, which can cause discomfort and pain to the feet when worn for a long period of time. [Prior art documents] [Patent documents]

[0038] As shown in Figs. 1 to 7b, the safety shoe 10 according to the first embodiment of the present invention is a safety shoe 10 to be worn by a wearer's foot F, and comprises an insole 110 on which the wearer's foot F is placed, a midsole 120 provided under the insole 110, an outsole 130 provided under the insole 110 and midsole 120 and forming the sole of the safety shoe 10, an outer skin 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10, and a support for the little toe LT of the foot F. The safety shoe 10 may be configured to include a toe cap 200 having a recess 260 formed in a concave shape in a forward direction at the position thereof, a protruding member 400 provided on the inside of the outer shell 140 so as to be positioned at a position corresponding to the little toe LT of the foot F, the protruding member 400 protruding outward in a convex shape and having an internal space 411 on the inside where the little toe LT can move, and a connecting member 300 provided inside the toe of the safety shoe 10, having a shape corresponding to the recess 260 and having a protrusion 310 that fits into the recess 260, and is provided behind the toe cap 200 to be connected to the toe cap 200.

[0039] The insole 110 is the part on which the wearer's foot F rests and comes into contact with the sole, and is located above the midsole 120.

[0040] The insole 110 is also located above the folded portion 250 of the toe cap 200 .

[0041] A midsole 120 and an outsole 130 are provided below the insole 110 .

[0042] An outsole 130 that forms the bottom of the safety shoe 10 is provided below the midsole 120 .

[0043] An outer skin 140 that encases the wearer's foot F is provided on top of the midsole 120 and the outsole 130.

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

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

[0046] As described above, the safety shoes 10 are provided with a midsole 120 and an outsole 130 provided below the midsole 120, thereby having a multi-layered outsole structure in which the outsole 130 forms the sole of the safety shoes 10.

[0047] Alternatively, the safety shoe 10 may have a single-layer outsole structure in which the midsole 120 or the outsole 130 forms the sole of the safety shoe 10 by only including the midsole 120 or the 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 include a front wall 210 that forms the front surface of the toe cap 200, an upper wall 220 that forms the upper surface of the toe cap 200, a thumb side wall 230 that forms the side surface of the toe cap 200 on the thumb side, a little finger side wall 240 that forms the side surface of the toe cap 200 on the little finger side, a bent portion 250 that is formed by bending and extending from the lower portions 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 in the forward direction of the toe cap 200 and opens at least a portion 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 respectively form the front, top, and both side surfaces of the toe cap 200, and a bent portion 250 formed by bending and extending from the lower portion of each of the front wall 210, the thumb side wall 230, and the little finger side wall 240 so as to form part of the bottom surface of the toe cap, and a recess 260 may be provided at the rear end of the little finger side wall 240 which is concave from the rear end of the little finger side wall 240 toward the front of the toe cap 200 and opens at least a portion of the rear end of the little finger side wall 240.

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

[0051] The front wall 210, the top wall 220, the thumb side wall 230, and the little finger side wall 240 are integrally formed to extend from one another, and each of the front wall 210, the top wall 220, the thumb side wall 230, and the little finger side wall 240 is curved and narrows toward the front of the toe cap 200, forming an overall streamlined shape.

[0052] The bent portions 250 are formed to be bent and extend from the lower portions 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 has a "U" shape as a whole. Therefore, the bottom surface of the toe cap 200 has a "U" shape with an open interior.

[0054] The folded portion 250 is folded toward the bottom surface of the toe cap 200 so that the angles formed between the inner surfaces of the front wall 210, the thumb side wall 230, and the little finger side wall 240 and the top surface of the folded portion 250 are 90° or more. In this case, the width of the folded portion 250 is several mm to several tens of mm.

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

[0056] When the safety shoe 10 is provided with the toe cap 200 , the insole 110 is located above the bent portion 250 .

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

[0058] The top wall 220 extends from the central rear end of the front wall 210 and forms the top surface of the toe cap 200 .

[0059] The upper wall 220 functions to protect the toes of the shoe wearer from falling objects by covering the top of the toes of the shoe wearer.

[0060] The big toe side wall 230 extends from the rear end of the front wall 210 on the big toe side, and forms a side surface of the toe cap 200. As shown in FIGS. 1 to 5b, when the safety shoe 10 is a safety shoe 10 for a right foot, the big toe side wall 230 of the toe cap 200 forms the left side surface of the toe cap 200.

[0061] The thumb side wall 230 has a shape that slopes toward the thumb as it goes rearward. In this case, the thumb side wall 230 has a curved line with a certain curvature, thereby having a streamlined shape.

[0062] The little toe side wall 240 extends from the rear end of the front wall 210 on the little toe side and forms a side surface of the toe cap 200. When the safety shoe 10 is a safety shoe 10 for a right foot, the little toe side wall 240 of the toe cap 200 forms the right side surface of the toe cap 200.

[0063] The little finger side wall 240 is provided with a recess 260 .

[0064] The recess 260 is formed in a concave shape from the rear end of the little toe side wall 240 toward the front of the toe cap 200. Therefore, the recess 260 leaves at least a portion of the rear end of the little toe side wall 240 open.

[0065] As shown in FIG. 6, such a recess 260 serves to prevent the little toe LT from contacting the little toe side wall 240 of the toe cap 200 when the wearer puts on the safety shoes 10.

[0066] In other words, the recess 260 is formed at a position corresponding to the location of the little toe LT when the wearer wears the safety shoes 10 with the toe cap 200, thereby functioning to prevent the little toe LT from contacting the little toe side wall 240 of the toe cap 200.

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

[0068] The recess 260 is formed at a position spaced apart upward from the bent portion 250 , thereby forming a spaced apart portion 241 between the recess 260 and the bent portion 250 .

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

[0070] In other words, the recess 260 is formed at a position spaced 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 below the recess 260.

[0071] As described above, by forming the separating 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 can further maximize the function of the recess 260 in absorbing 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. In other words, the thumb side wall 230 and the little finger side wall 240 of the toe cap 200 have asymmetrical shapes.

[0074] The protruding member 400 is provided on the outer side of the toe cap 200 and the inner side of the outer shell 140 so as to be positioned at a position 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 shell 140.

[0075] The protruding member 400 can be configured to include a protruding portion 410 having an internal space 411 formed on the inside and formed convexly on the outside, a frame portion 420 provided along the periphery of the protruding portion 410, and a joint 430 consisting of an area where the protruding portion 410 and the frame portion 420 are connected.

[0076] The protrusion 410 is formed in a shape that protrudes outward from the frame 420 so that an internal space 411 is formed inside.

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

[0078] The protrusion 410 may have a pentagonal shape as a whole. In this case, it is preferable that the rear of the protrusion 410 is formed so as to have the longest side of the five sides of the pentagon of the protrusion 410.

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

[0080] The frame portion 420 has a flat shape, and the protrusion portion 410 protrudes outward from the frame portion 420 .

[0081] The outer surface of the frame portion 420 is located more inward than the outer surface of the protrusion portion 410 .

[0082] An internal space 411 is formed inside the inner surface of the protruding portion 410 , and as a result, the inner surface of the frame portion 420 is located more inward than the inner surface of the protruding portion 410 .

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

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

[0085] The joint 430 is formed by the area where the protrusion 410 and the frame 420 are connected.

[0086] If the protrusion 410 has a pentagonal shape, the joint 430 may have five sides to correspond to the pentagonal shape of the protrusion 410. Thus, the joint 430 is formed so that it is all closed.

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

[0088] The protruding member 400 is located outside the recessed portion 260 of the toe cap 200. Specifically, as shown in Fig. 6, the protruding portion 410 of the protruding member 400 is located at a position corresponding to the recessed portion 260 of the toe cap 200. Therefore, the recessed portion 260 is located inside the internal space 411 of the protruding portion 410.

[0089] The protruding members 400 also cause the outer skin 140 to protrude outward in a convex shape. Therefore, the shape of the protruding members 400 can be seen from the overall appearance of the safety shoes 10.

[0090] The toe cap 200, the protruding member 400, and the outer shell 140 may be integrally molded by joining them together using thermocompression, etc. Therefore, the position of the protruding member 400 is fixed, and the internal space 411 of the protruding portion 410 may be continuously positioned outside the recess 260, thereby ensuring a space that ensures the movement of the little toe LT.

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

[0092] A protrusion 310 is provided on one side of the coupling 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 coupling member 300 at a position corresponding to the recess 260.

[0095] With the protrusion 310 fitted into the recess 260, the coupling member 300 and the toe cap 200 are coupled in the front-rear direction.

[0096] The connecting member 300 is made of a soft material, and therefore serves to prevent the wearer's instep from coming into contact with the rear part 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 coupled together by the coupling member 300 , the internal space 411 of the protrusion 410 is located outside the convex portion 310 .

[0098] In the safety shoes 10 according to the first embodiment of the present invention described above, the recessed portion 260, the convex portion 310 and the protruding portion 410 are located at positions corresponding to the little toe LT.

[0099] Space for the wearer's little finger LT to move is ensured via these recessed portions 260, convex portions 310, and protruding portions 410. Therefore, the wearer can prevent the little finger LT from coming into contact with the inner surface of the outer shell 140 or the little finger side wall 240 of the toe cap 200, which could cause discomfort or pain.

[0100] Specifically, conventional safety shoes have a problem in that the wearer's toes touch the inside of the outer shell or the inside of the toe cap, causing discomfort. In particular, in the case of safety shoes equipped with a toe cap, if the toe cap is made larger to solve this problem, the size of the safety shoes becomes larger and heavier, resulting in a problem of poor fitting.

[0101] In order to solve this problem, 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 space is secured so that the little toe LT can be removed outward. This ensures space without making the safety shoe 10 or toe cap 200 larger, thereby improving comfort while maintaining the fitting feel of the safety shoe 10.

[0102] Furthermore, because 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 presence of the protrusion 310. That is, 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 ensuring free movement of the little finger LT.

[0103] As described above, the free movement of the little toe LT is ensured, so that the wearer can feel comfortable wearing the safety shoes 10 even though the outer skin 140 of the safety shoes 10 is made of a hard material.

[0104] The safety shoes 10 according to the first embodiment of the present invention described above can secure space for the little toe LT through the protruding member 400 even if the toe cap 200 is not provided.

[0105] Safety shoes 10a according to a second embodiment of the present invention Hereinafter, a safety shoe 10a according to a second embodiment of the present invention will be described with reference to FIG.

[0106] FIG. 8 is a perspective view showing a state in which the outer cover has been removed from the safety shoes according to the second embodiment of the present invention.

[0107] As shown in FIG. 8, the safety shoe 10a according to the second embodiment of the present invention includes an insole 110 on which the wearer's foot F is placed, a midsole 120 provided under the insole 110, an outsole 130 provided under the insole 110 and midsole 120 and forming the sole of the safety shoe 10a, an outer skin 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10a, and a toe cap having a recess 260 formed in a concave shape in the forward direction at the position of the little toe LT of the foot F. The safety shoe 10a can be configured to include: a toe cap 200; a protruding member 400 that is provided on the inside of the outer shell 140 so as to be positioned at a position corresponding to the little toe LT of the foot F, and that protrudes convexly outward and has an internal space 411 on the inside where the little toe LT can move; a connecting member 300 that is provided inside the toe of the safety shoe 10a, has a shape corresponding to the recess 260, has a protrusion 310 that fits into the recess 260, is located behind the toe cap 200, and is connected to the toe cap 200; and a soft member 470 that is provided on the inside of the protrusion 410 of the protruding member 400.

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

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

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

[0111] The soft member 470 may be made of a soft, flexible material, such as sponge, EVA, or the like.

[0112] The soft member 470 described above is provided inside the internal space 411, and serves the function of preventing the little toe LT from coming into direct contact with the inside of the protruding portion 410, thereby improving comfort when wearing the shoes.

[0113] That is, since the little toe LT comes into direct contact with the soft, fluffy member 470, the wearer can feel an even better wearing comfort than if the little toe LT were to come into direct contact with the inside of the protruding portion 410 of the relatively hard protruding member 400.

[0114] The soft member 470 may be attached to the inside of the protruding portion 410 of the protruding member 400 by adhesive or the like.

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

[0116] Safety shoes 10b according to a third embodiment of the present invention A safety shoe 10b according to a third embodiment of the present invention will now be described with reference to Figs. 9 to 11b.

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

[0118] As shown in Figs. 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 is placed, a midsole 120 provided under the insole 110, an outsole 130 provided under the insole 110 and midsole 120 and forming the sole of the safety shoe 10b, an outer skin 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10b, and a recessed part 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10b. The safety shoe 10b may include a toe cap 200 having a recess 260 formed therein, a protruding member 400b provided on the inside of the outer shell 140 so as to be positioned at a position corresponding to the little toe LT of the foot F, the protruding member 400b protruding outward in a convex shape and having an internal space 411 formed on the inside in which the little toe LT can move, and a connecting member 300 provided inside the toe of the safety shoe 10b, having a shape corresponding to the recess 260 and having a convex portion 310 that fits into the recess 260, and is disposed behind the toe cap 200 to connect to the toe cap 200.

[0119] In the safety shoes 10b according to the third embodiment of the present invention, the shape of the protruding member 400b is different from the shape of the protruding member 400 of the safety shoes 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 shoes 10 according to the first embodiment of the present invention, and redundant description will be omitted.

[0120] The protruding member 400b is provided on the outer side of the toe cap 200 and the inner side of the outer shell 140 so as to be positioned at a position 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 shell 140.

[0121] The protruding member 400b can be configured to include a protruding portion 410b having an internal space 411b formed on the inside and a convexly formed protruding portion 410b on the outside, a frame portion 420b provided along the periphery of the protruding portion 410b, and a joint 430b consisting of an area where the protruding portion 410b and the frame portion 420b are connected.

[0122] The protrusion 410b is formed in a shape that protrudes outward from the frame 420b so that an internal space 411b is formed inside.

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

[0124] The protrusion 410b may have a generally pentagonal shape.

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

[0126] For example, the frame portion 420b is provided along the front, top, and bottom of the protrusion 410b except for the rear thereof, i.e., along the periphery of the protrusion 410b except for the rear thereof.

[0127] The frame portion 420b has a flat shape, and the protrusion portion 410b protrudes outward from the frame portion 420b.

[0128] The outer surface of the frame portion 420b is located more inward than the outer surface of the protrusion 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 more inward than the inner surface of the protruding portion 410b.

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

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

[0132] The joint 430b is formed by the area where the protrusion 410b and the frame 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 so that the area except for the area behind the joint 430b is closed.

[0135] When the protrusion 410b has a pentagonal shape, the frame 420b is provided along the periphery of the protrusion 410b except for the rear side, so the rear side of the joint 430b is also open. Therefore, the joint 430b is not formed in the area corresponding to the rear side of the protrusion 410b. As a result, the joint 430b is made up of the remaining four faces excluding the face corresponding to the rear side of the protrusion 410b.

[0136] Due to the shapes of the protrusion 410b, the frame 420b, and the joint 430b, the internal space 411b of the protrusion 410b is open at the inside and rear and closed at the front, top, bottom, and outside.

[0137] The boundary lines of the four faces of the joint 430b are connected to the vertices of the protrusion 410b, so that when the protrusion 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 recessed portion 260 of the toe cap 200. The protruding portion 410b of the protruding member 400b is located at a position corresponding to the recessed portion 260 of the toe cap 200. Therefore, the recessed portion 260 is located inside the internal space 411b of the protruding portion 410b.

[0139] The protruding members 400b also cause the outer skin 140 to protrude outward in a convex shape. Therefore, the shape of the protruding members 400b can be seen from the overall appearance of the safety shoes 10.

[0140] The toe cap 200, the protruding member 400b, and the outer shell 140 can be integrally molded by joining them together using thermocompression, etc. Therefore, 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 ensures the movement of the little toe LT.

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

[0142] In other words, the safety shoes 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 shoes 10b, thereby ensuring good wearing comfort of the safety shoes 10b.

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

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

[0145] Also, even when a protrusion 141e is formed on the inside of the outer shell 140, as in the safety shoes 10e according to the sixth embodiment, the joint 142e may have a rear-open form, i.e., the rear of the joint 142e is open, and the front, upper, and lower parts except for the rear are closed.

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

[0147] Figure 12 is a perspective view showing the state in which the outer skin has been peeled off 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 the safety shoe according to the fourth embodiment of the present invention, and Figure 13c is a plan view of the toe cap of the safety shoe according to the fourth embodiment of the present invention.

[0148] As shown in FIG. 8, a safety shoe 10c according to a fourth embodiment of the present invention may include 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 sole of the safety shoe 10c, a toe cap 200c provided inside the toe of the safety shoe 10c and having a protrusion 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 on the inside to allow the little toe LT to move, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 to encase the toe cap 200c and the wearer's foot F and form the shape of the safety shoe 10c, and a connecting member 300 provided inside the toe of the safety shoe 10c, positioned behind the toe cap 200c and connected to the toe cap 200c.

[0149] In the safety shoes 10c according to the fourth embodiment of the present invention, the protrusion 270c is integrally formed with the toe cap 200c, and the shapes of the toe cap 200c and the connecting member 300 are different from those of the safety shoes 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 substituted with the description of the safety shoes 10 according to the first embodiment of the present invention, and redundant description will be omitted.

[0150] The toe cap 200c is provided inside the toe of the safety shoe 10c, and can include a front wall 210 forming the front surface of the toe cap 200c, an upper wall 220 forming the upper surface of the toe cap 200c, a thumb side wall 230 forming the side surface of the toe cap 200c on the thumb side, a little finger side wall 240 forming the side surface of the toe cap 200c on the little finger side, a bent portion 250 formed by bending and extending from the lower portions of the front wall 210, the thumb side wall 230, and the little finger side wall 240 and forming part of the bottom surface of the toe cap 200c, and a protruding portion 270c formed by protruding convexly outward from the rear end of the little finger side wall 240.

[0151] The toe cap 200c has a front wall 210, an upper wall 220, a thumb side wall 230, and a little finger side wall 240 which respectively form the front, top, and both side surfaces of the toe cap 200, and a bent portion 250 which is formed by bending and extending from the lower portion of each of the front wall 210, the thumb side wall 230, and the little finger side wall 240 so as to form part of the bottom surface of the toe cap.

[0152] The protrusion 270c is formed so as to bulge outward from the rear end of the little finger sidewall 240 and recess inward so as to correspond to the position of the little finger LT.

[0153] The protrusion 270c is formed in a shape that protrudes outward from the little finger side wall 240 so that an internal space 271c is formed inside.

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

[0155] The protrusion 270c has a generally rectangular shape.

[0156] An internal space 271c is formed inside the inner surface of the protruding portion 270c, and as a result, the inner surface of the little finger side wall 240 is located more inward than the inner surface of the protruding portion 270c.

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

[0158] Joint 273c comprises the area where protrusion 270c and 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 so that the area except for the area behind the joint 273c is closed.

[0161] The protrusion 270c has a rectangular shape, and the joint 273c is not formed in the area corresponding to the rear of the protrusion 270c so that the rear of the joint 273c is open. As a result, the joint 273c is made up of the remaining three faces excluding the face corresponding to the rear of the protrusion 270c.

[0162] The boundary lines of the three faces of the joint 273c are connected to the vertices of the protrusion 270c, so when the protrusion 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 is open on the inside and rear, and closed on the front, top, bottom, and outside.

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

[0165] The connecting member 300 is disposed behind the toe cap 200c and is connected to the toe cap 200c in the front-to-rear direction. In the safety shoe 10c according to the fourth embodiment of the present invention, the toe cap 200c does not have a recess formed therein, and therefore the connecting member 300 does not have a separate protrusion formed therein.

[0166] The above-described protrusion 270c of the toe cap 200c ensures a sufficient space for the wearer's little toe LT to move in the safety shoes 10c, thereby preventing the wearer from feeling cramped or inducing pain due to the little toe LT coming into contact with the inner surface of the outer shell 140 or the little toe side wall 240 of the toe cap 200c.

[0167] As described above, the free movement of the little toe LT is ensured, and therefore the wearer can feel comfortable wearing the safety shoes 10c, even though the outer skin 140 of the safety shoes 10c is made of a hard material.

[0168] Furthermore, since the protrusion 270c is formed integrally with the toe cap 200c, the position of the protrusion 270c can be easily fixed, which makes it easy to manufacture the safety shoes 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 the joint 273c can be formed by being molded integrally with the toe cap 200c. In this case, the protrusion 270c and the joint 273c can be formed by applying a process such as pressing to the little toe side wall 240 of the toe cap 200c. When the protrusion 270c and the 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] Unlike the above, the protrusion 270c and the joint 273c may be manufactured separately from the toe cap 200c. In this case, a recess is formed in the rear end of the toe cap 200c, and the protrusion 270c and the joint 273c are provided to enclose the recess. Therefore, the space opened by the recess and formed inside the protrusion 270c and the joint 273c becomes the internal space 271c. The protrusion 270c and the joint 273c may be attached to the toe cap 200c with an adhesive or the like. When the protrusion 270c and the joint 273c are formed separately from the toe cap 200c in this way, the toe cap 200c, the protrusion 270c, and the joint 273c are made of different materials. However, the protrusion 270c and the joint 273c may be made of the same material.

[0172] Safety shoes 10d according to a fifth embodiment of the present invention Hereinafter, a safety shoe 10d according to a fifth embodiment of the present invention will be described with reference to FIG.

[0173] FIG. 14 is a diagram showing a state in which a wearer's foot is put on the safety shoes according to the fifth embodiment of the present invention.

[0174] As shown in FIG. 14, a safety shoe 10d according to a fifth embodiment of the present invention can include 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 sole of the safety shoe 10d, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10d, a toe cap 200d provided inside the toe of the safety shoe 10d and positioned forward of the little toe LT of the foot F, and a protruding member 400 provided inside 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 on the inside in which the little toe LT can move.

[0175] The safety shoes 10d according to the fifth embodiment of the present invention have the same configuration as the safety shoes 10d according to the first embodiment of the present invention described above, except for the shape of the toe cap 200d. Therefore, the description of the same configuration can be replaced with the description of the safety shoes 10 according to the first embodiment of the present invention described above, and redundant description will be omitted.

[0176] The toe cap 200d may include a front wall 210 forming the front surface of the toe cap 200d, an upper wall 220 forming the upper surface of the toe cap 200d, a thumb side wall 230 forming the side surface of the toe cap 200d on the thumb side, a little finger side wall 240 forming the side surface of the toe cap 200d on the little finger side, and a folded portion 250 formed by folding and extending from the lower portions of the front wall 210, the thumb side wall 230, and the little finger side wall 240 and formed to form a part of the bottom surface of the toe cap 200d.

[0177] In the safety shoes 10d according to the fifth embodiment, no separate recess is provided in the toe cap 200d.

[0178] The toe cap 200d has a rear end portion 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 some of the toes of the foot F. The little finger side wall 240 of the toe cap 200d is located inside the protruding member 400.

[0179] The little finger LT can move outward within the internal space 411 of the protruding portion 410. That is, since a space is secured by the internal space 411, the free movement of the little finger LT is guaranteed.

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

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

[0182] Safety shoes 10e according to a sixth embodiment of the present invention A safety shoe 10e according to a sixth embodiment of the present invention will now be described with reference to FIGS.

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

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

[0185] The safety shoes 10e according to the sixth embodiment of the present invention differ only in that the protrusion 141e is integrally formed with the outer shell 140e, and the remaining components have the same configuration as the safety shoes 10e according to the first embodiment of the present invention described above. Therefore, the description of the same configuration can be replaced with the description of the safety shoes 10 according to the first embodiment of the present invention described above, and redundant description will be omitted.

[0186] The outer skin 140e can be configured to include an internal space 143e formed inside, a protrusion 141e formed in a convex shape on the outside, and a joint 142e consisting of an area where the protrusion 141e and the outer skin 140e are connected.

[0187] The protrusion 141e is formed in a shape that protrudes outward from the outer cover 140e so as to form an internal space 143e inside. In this case, the protrusion length of the protrusion 141e is preferably 2 mm or more and 4 mm or less.

[0188] The protrusion 141e may have a pentagonal shape as a whole, in which case it is preferable that the rear of the protrusion 141e is formed so as to have the longest side of the five sides of the pentagon of the protrusion 141e.

[0189] An internal space 143e is formed inside the inner surface of the protruding portion 141e, and as a result, the inner surface of the outer skin 140e is located more inward than the inner surface of the protruding portion 141e.

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

[0191] The joint 142e is formed by the area where the protrusion 141e and the outer skin 140e are connected.

[0192] If the protrusion 141e has a pentagonal shape, the joint 142e may have five faces corresponding to the pentagonal shape of the protrusion 141e, and thus the joint 142e is formed to be completely closed.

[0193] The boundary lines of the faces of the joint 142e are connected to the vertices of the protrusion 141e, so if the protrusion 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. Specifically, the protrusion 141e is located at a position corresponding to the recess 260 of the toe cap 200. Therefore, the recess 260 is located inside the internal space 143e of the protrusion 141e.

[0195] The protrusion 141e and the joint 142e can be formed on the outer cover 140e by subjecting the outer cover 140e to heat processing, press processing, or the like.

[0196] As described above, when the protrusion 141e and the joint 142e are provided on the outer cover 140e, a separate protrusion member is not required, which simplifies the manufacturing process and prevents the protrusion 141e from shifting out of position due to the movement of the protrusion member.

[0197] Safety shoes 10f according to a seventh embodiment of the present invention Hereinafter, a safety shoe 10f according to a seventh embodiment of the present invention will be described with reference to FIG.

[0198] FIG. 17 is a perspective view showing a state in which the outer cover has been removed from the safety shoes according to the seventh embodiment of the present invention.

[0199] As shown in FIG. 17, a safety shoe 10f according to a seventh embodiment of the present invention may include 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 sole of the safety shoe 10f, an outer shell 140 provided on the upper part of the midsole 120 and outsole 130 so as to encase the wearer's foot F and form the shape of the safety shoe 10f, a toe cap 200 having a recess 260 formed in a concave shape facing forward 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 on the inside to allow the little toe LT to move, and a connecting member 300f provided inside the toe of the safety shoe 10f, positioned behind the toe cap 200, and connected to the toe cap 200.

[0200] The safety shoes 10f according to the seventh embodiment of the present invention have the same configuration as the safety shoes 10 according to the first embodiment of the present invention described above, except for the shape of the connecting member 300f. Therefore, the description of the same configuration can be replaced with the description of the safety shoes 10 according to the first embodiment of the present invention described above, and redundant description will be omitted.

[0201] The connecting member 300f is disposed at the rear of the toe cap 200 and connects to the toe cap 200 in the front-rear direction.

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

[0203] The connecting member 300f is formed so that the little finger LT side of the connecting member 300f is short so that the connecting member 300f is not positioned in the recess 260. In other words, the connecting member 300f does not have a little finger side surface that corresponds to the little finger LT. Therefore, the recess 260 remains an empty space.

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

[0205] Since the joining member 300f is not positioned in the recess 260, there is an advantage in that the degree of freedom of the little finger LT is ensured via 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 mentioned above, the present invention has been described with reference to preferred embodiments, but those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
