Definitions

  • the present invention relates to a toe cap for footwear and an outsole integrated with the toe cap, more specifically, to a toe cap for footwear and an outsole integrated with the toe cap wherein the toe cap has an inclination in the upper end thereof declining gradually from a big toe to a little toe, and a winding shape corresponding, in shape, to appearance of human toe, and in case of the outsole integrated with the toe cap, the outsole has, adjacent to the front upper end thereof, support groove for supporting each of the toes.
  • the footwear are produced by covering the last of foot shape with a leather upper forming appearance shape of a shoe, adhering the sole to the bottom of the obtained last, and then removing the last therefrom. As a result, it is possible to obtain a wearable shoe having a space corresponding to the shape of the removed last.
  • the sole is roughly classified into three parts such as an outsole which contacts with the ground, an insole which is separably disposed in the footwear to contact with foot sole of human body, and a midsole which is disposed between the outsole and the insole to contact with an upper end of the outsole.
  • US Patent No. 4,294,022 discloses a boots with which a toe cap is integrally formed to cover the outsole and the foot toes of human body.
  • Korean Utility Model Registration No. 20-(34)0751 discloses a house footwear in which a toe cap is integrated with the sole on the area adjacent the front end of human foot, is extended to the top side of the leather upper, and is closely and firmly secured to the exterior surface of the leather upper.
  • the said two reference materials have a common characteristic in that the outsole is integrated with the toe cap covering the toes to be able to protect the toes against a possible external impact.
  • the big toe having the relatively bigger than any other toes in both size and height thereof receives relatively greater pressure than any other toes, thereby occurring the pains, even in worst, some diseases such as plantar fasciitis and interdigital neuroma, whereas the little toe having relatively smaller size than any other toes tends to be easily moved in the footwear, thereby leading to a marked deterioration of the fitting ability.
  • the toe cap contacting with the forward ends of the toes has a shape closely similar to that of the toes of human foot. Accordingly, the object of present invention is to provide a toe cap for footwear and an outsole integrated with the toe cap wherein the toe cap has a shape corresponding, in shape, to human toes, based on anatomy of human foot so that it is possible to improve wearing feeling and fitting feeling, and protect the foot or toes against exterior impact.
  • one aspect according to the preferable embodiments of the present invention provides a toe cap for footwear, for covering toes of human body, characterized in that the toe cap (30) is highest at a big toe (41) region and gradually slopes downward toward the little toe (45).
  • an angle (D) of downward inclination of the upper end of the toe cap (30) is within a range between 5° to 25° in the shape of the sloped circular arcs.
  • Another aspect according to the preferable embodiments of the present invention provides a toe cap for footwear, for covering toes of human body, characterized in that the toe cap (30) has the shape of a circular arc along the outer shape of the toes, and the first to fourth grooves (31) to (34) are formed at four position between the five toes (41) to (45) respectively, so as to support each toe.
  • outsole (20) integrated with the toe cap is characterized by having a support groove (21) which is formed at a front upper end surface to accommodate the bottom surface of at least one or more of the toes (41) to (45).
  • the toe cap has a winding shape along with the outer shape of human toes, and particular characteristic structure in that the toe cap has a downward inclination of the upper end of the tow cap from the big toe to the little toe so as to support each toes, respectively, thereby being able to provide improved wearing feeling and fitting feeling, and enhancing the activity of foot. Furthermore, the toe cap has higher strength due to uneven structure thereof, so that the toes can be safely protected against a strong external impact which may occur frequently outside of the footwear.
  • the outsole integrated with the toe cap has support the groove for accommodating the bottom of each toe respectively which provides further improvement for wearing feeling and fitting feeling of the footwear.
  • Fig. 1 is a perspective view illustrating only a main region of the footwear according to present invention
  • Fig. 2 is a front view illustrating a main region of toe cap of the footwear according to present invention
  • Fig. 3 is a sectional view taken along a line A-A of Fig. 2 illustrating winding shape of the toe cap;
  • Fig. 4 is a partly-longitudinal sectional view illustrating outsole integrated with the toe cap according to present invention.
  • one aspect according to the preferable embodiments of the present invention provides a toe cap for footwear, for covering toes of human body, characterized in that the toe cap (30) is highest at a big toe (41) region and gradually slopes downward toward the little toe (45).
  • an angle (D) of downward inclination of the upper end of the toe cap (30) is within a range between 5° to 25° in the shape of the sloped circular arcs.
  • Another aspect according to the preferable embodiments of the present invention provides a toe cap for footwear, for covering toes of human body, characterized in that the toe cap (30) has the shape of a circular arc along the outer shape of the toes, and the first to fourth grooves (31) to (34) are formed at four position between the five toes (41) to (45) respectively, so as to support each toe.
  • outsole (20) integrated with the toe cap is characterized by having a support groove (21) which is formed at a front upper end surface to accommodate the bottom surface of at least one or more of the toes (41) to (45).
  • Fig. 1 is a perspective view illustrating only a main region of footwear according to present invention
  • Fig. 2 is a front view illustrating a main region of toe cap of footwear according to present invention
  • Fig. 3 is a sectional view taken along a line A-A of Fig. 2 illustrating winding shape of the toe cap.
  • the footwear includes leather upper (10) for covering a top side of foot.
  • An outsole (20) is formed on the leather upper (10), and a toe cap (30) for protecting human body's toes is formed on the forward side of footwear.
  • the toe cap (30) having the characteristic structure may be formed separately or integrally with the outsole (20).
  • the toe cap (30) having a shape corresponding to the appearance shapes of five toes (41) to (45).
  • the toe cap (30) is highest at a big toe (41) and gradually slopes downward toward the little toe (45) (See Fig. 2 ).
  • the toe cap (30) has the inclination in the upper end because the toes of human foot have sizes decreasing gradually from the big toe of the biggest size (height) to the little toe of the lowest size (height).
  • the height of the toe cap (30) in upper end is designed to correspond to outer shape of toes, and also the middle region (11) of the leather upper (10) is connected with the upper end of the toe cap (30) to cover a top side of foot.
  • an inclination angle (D) of the upper end of the toe cap (30) can be varied by adjustment within a range between 5° to 25°. Because the upper end of the toe cap (30) has a curved line, not linear line, the angle (D) of the upper end can be adjusted within the range. More specifically, the upper end of the toe cap has a curve, extending from the highest height of big toe to the lowest height of little toe. The position points of the curve according to the toes have different angles along with the upper end of the toe cap, respectively, so that inclination angles of the position points may be adjusted within the range between 5° to 25°, when the upper end of the toe cap (30) is designed as downwardly inclined.
  • the toe cap (30) has, in front end, a circular arc shape along the outer shape of each toe (41) to (45).
  • the circular arc shape of the toe cap has first to fourth grooves (31) to (34) corresponding to four grooves formed between five toes (41) to (45).
  • the first groove (31) corresponds to, in shape, a groove formed between the big toe (41) and the second toe (42)
  • the second groove (32) corresponds to, in shape, a groove defined between the second toe (42) and third (middle) toe (43)
  • the third groove (33) corresponds to, in shape, a groove defined between the third toe (43) and the fourth toe (44)
  • the fourth groove (34) corresponds to, in shape, a groove defined between the fourth toe (44) and the little (fifth) toe (45).
  • the toes (41) to (45) are supported by the grooves (31) to (34), respectively, the toes are not easily moved in the toe cap such that the fitting feeling is enhanced.
  • a protrusion formed between the first groove (31) and the second groove (32) prevents the second toe (42) from being moved in the lateral direction in the toe cap, and similarly a protrusion formed between the second groove (32) and the third groove (33) prevents the third (middle) toe (43) from being moved in the lateral direction in the toe cap.
  • the toe cap (30) may further include a fifth groove (35) for supporting a forward - inner region (41)' of the big toe (41).
  • the big toe (41) is located between the first groove (31) and the fifth groove (35), and simultaneously supported in the lateral direction such that the fitting feeling is highly enhanced.
  • the toe cap (30) may further include a sixth groove (36) for supporting a side inner region (41 ") of the big toe (41).
  • the toe cap has a shape corresponding closely to the exterior appearance of the entire toes so that it is possible to support entirely the big toe loaded with the biggest impact upon walking, and to very highly enhance both the wearing feeling and the fitting feeling.
  • Fig. 4 is a partly-longitudinal sectional view illustrating outsole integrally formed with the toe cap according to present invention.
  • the outsole (20) may include, adjacent to the front upper end thereof, support groove (21) for supportably accommodating at least one of the toes (41) to (45).
  • the support groove (21), as shown in Fig. 4 is formed in the shape of puddles to supportably receive bottoms of the toes prevented from being moved in the lateral direction of the toe cap.
  • the support groove (21) may be formed to correspond, in shape, to all of the five toes, or one or more selected from the five toes, if necessary.
  • the support groove (21) may have only one groove for corresponding to the big toe (41), or two grooves for corresponding to the big toe (41) and the second toe (42). In other words, the number of recesses may be variously selected according to use, if necessary.
  • the toe cap having a shape corresponding, complementarily in shape, to the outer shapes of five toes, and also, the toe cap has an downward inclination in the upper end thereof declining gradually from the big toe of the highest height to the little toe of the lowest height. Because the five toes can be supported, respectively, due to the characteristic structure mentioned above, the wearing feeling and the fitting feeling can be improved to increase activity of foot. Furthermore, the toe cap has uneven structure of surface such that strength of the toe cap can be enhanced to protect human foot even against the impact from the outside.
