Description

A SHOE HAVING TURNING AND STAMPING FUNCTION AND LOWER STRUCTURE FOR THE SHOE

Technical Field

[1] The present invention relates to a functional health shoe having a turning and stamping function and a lower structure for the shoe. Background Art

[2] The present invention relates to a functional shoe having a turning function, and more particularly to a functional shoe by which a wearer can easily perform an exercise of twisting their body while holding a wall, or the like, anytime and anywhere.

[3] A shoe for various sports includes an upper and a sole assembled with a lower side of the upper. The conventional shoe has been developed emphasizing on improvement of durability, lightness, and wearing sensation. However, there is no function rather than a function of the shoe itself. Recently, a shoe having wheels assembled with the sole has been developed, through which a wearer can exercise/play the movement on a ground using the wheels, like roller skates, or the like. However, it is very uncomfortable for the wearer to walk while wearing the shoe having the wheels, and various problems occurs of sliding and being injured during a gait cycle, or the like.

[4] The present invention relates to a shoe having a turning and stamping function, in which a rotation means is mounted on a front portion of a mid- sole so that a wearer can perform an exercise of twisting their body while holding a wall anytime and anywhere, and stamping on a ground occurs during the gait cycle so that the impact is decreased, and joints of a knee and an ankle and the waist are protected. Further, side spaces are formed in both edges of a rear heel region of the shoe so as to occur a second stamping, so that the impact is decreased, and joints of the knee and the ankle and the waist are protected.

[5] Generally, the motion of foot against the ground upon walking includes three steps, i.e., a step of landing by a rear heel of the foot; a step of center shifting from the rear heel to a forefoot; and a step of disengagement from the ground while the forefoot pushes on the ground, and those steps are continuously repeated in the right foot and a left foot. In the conventional shoe, the rear heel region of the shoe crosses at an almost right angle with respect to the ground, and a heeled shoe has a rear heel with a keen edge, so that the edge first comes into contact with the ground. Then, the edge of the rear heel region of the shoe is formed with a linear shape having a narrow attachment surface, so that the impact is high upon landing, and a shift to the step of the center shift is performed at one time. As a result, the sudden shock is delivered to every joint of the body including the ankle and the legs, so that the landing sensation is not good and the walking is not natural.

[6] The conventional shoe has been developed emphasizing on improvement of durability, lightness, and wearing sensation. However, there is no function rather than a function of the shoe itself. Conventionally, a shoe having the wheels assembled with the mid-sole of the shoe has been suggested, through which a wearer can perform an exercise of moving on the ground using the wheels, like roller skates. However, the shoe having the wheels is uncomfortable for general walking, and various problems occur of sliding and being injured upon walking, or the like.

[7] Further, the present invention relates to a lower structure for a shoe, and more particularly to a lower structure for a shoe which absorbs the impact and pressure generated upon walking with the shoe and improves air permeability, thus maintaining the health of the foot.

[8] The lower structure for the shoe forms a bottom part of the shoe which should absorb the impact delivered on the foot and maintain the health of the foot, considering the installation position. To this end, cushioning of the lower structure for the shoe itself and the air permeability is substantially important.

[9] FIGs. 36 to 39 illustrate a conventional lower structure for a shoe contrary to the present invention disclosed in the Korean Patent No. 638398 (issued on October 18, 2006, entitled "Sole of Shoes").

[10] The Korean Patent No. 638398 discloses a sole of a shoe in which a bottom surface of a front and a rear portion of the sole is upwardly inclined so that the bottom surface of the sole is shaped like a round arc, and a hard mid-sole is laid within the sole of shoe. Further, a cushion stamping sole shaped like an ellipse and made of a soft material, such as a sponge, is attached on a rear heel portion of the sole of the shoe so as to enable a wearer to stamp while absorbing the impact generated when the rear heel of the foot is stepped on the ground. Further, a leaf spring having a round shape is laid within a front and rear area of the cushion stamping sole so that a restoration speed by which the cushion stamping sole is compressed and then is expanded is fast, so as to absorb the shock. Further, a waterproof cover covers an external surface of the cushion stamping sole so as to prevent water from soaking into the cushion stamping sole made of a non- waterproof material.

[11] Referring to FIGs. 36 and 37, a sole assembly 10 has a structure in which the bottom surface of the front portion and the rear portion of the sole assembly are upwardly inclined so that the bottom surface of the sole is shaped like an arc, the hard mid-sole 30 is laid within the sole of shoes 10, a non-slip sole 40 is attached on an entire surface of the bottom surface of the sole assembly 10, and an arcuate volume- reducing part 11 is formed at a lower side of the rear portion of the sole assembly 10. The cushion stamping sole 20 shaped like the ellipse and being softer than the sole assembly 10 is attached on the arcuate volume-reducing part 11, and the non-slip sole 40 is attached on the entire surface of the bottom surface of the sole assembly 10 including a lower surface of the cushion stamping sole 20. Further, the waterproof cover (not shown) covers the external entire surface of the cushion stamping sole 20, and two leaf springs 22 made of metallic plates are laid within the front and rear portions of the cushion stamping sole 20 while facing each other in a front and a rear direction.

[12] In the meantime, as shown in FIGs. 38 and 39, the hard mid-sole 30 is bent in an arc shape, the same as that of the sole assembly 10, a front portion thereof is formed to be thin, a reinforcement portion 33 is formed on an upper surface of a bent waist portion, and an uneven surface 31 and through holes 32 are formed on entire surfaces of an upper and a lower portion of the hard mid-sole 30. Further, an incision part 34 is formed at both sides of a corresponding position of the toes in the front portion of the hard mid-sole in a widthwise direction, and an elastic support part 35 is formed between the incision part 34.

[13] Korean Patent No. 638398 discloses the shoe in which the arcuate volume-reducing part is formed on the lower side of the rear portion of the sole assembly having the round arc-shaped lower surface, and the cushion stamping sole shaped like the ellipse and is made of a material softer than that of the sole assembly is attached on the arcuate volume-reducing part so as to absorb the shock transferred to the rear heel and enable the wearer to effectively stamping- walk. Further, the hard mid-sole is firmly laid within the sole assembly so as to prevent separation of the hard mid-sole from the sole assembly, and achieve a comfortable movement of the toes without irritation on the plantar region of the foot.

[14] Further, Korean Patent No. 603062 (issued on July 12, 2006, entitled "Sole with the

Base Plane of Arc Shape) shown in FIGs. 40 and 41 discloses another conventional lower structure for a shoe.

[15] Korean Patent No. 603062 relates to a sole of a shoe in which bottom surface of a front portion and a rear portion of the sole is upward inclined so that the bottom surface of the sole is generally shaped like a round arc. The round bottom surface of the sole has a shape of consecutively connected arcs so that a bent line portion formed in a connected portion of the arcs protrudes more than the arc portion, like a gnarl of a bamboo. As a result, multiple bent line portions are stepped on upon walking so that the stepped portion continuously stimulates spots on the body suitable for acupuncture spread on the plantar region of the foot, thereby rhythmically stimulating the plantar region of the foot.

[16] Referring to FIG. 40, the sole includes a sole assembly 10 in which bottom surfaces of a front and rear portions of the sole assembly are upward inclined and shaped like a round arc, and a non-slip sole 20 attached on the lower surface of the sole assembly 10 and a bent line portion 12 downward bent formed on a portion where multiple arcuate concaves 11 shaped like an arc are consecutively connected.

[17] The non-slip sole 20 includes multiple arcuate convexes 21 corresponding to the arcuate concaves 11 and bent groove portions 22 corresponding to the bent line portions 12 formed on an upper surface of the non-slip sole 20, and unevenness entirely formed in a lower surface of the non-slip sole 20 for preventing slipping.

[18] In Korean Patent No. 603062 having the above configuration, the bent line portion formed in the connected portion of the arcs protrudes more than the arc portion like a gnarl of a bamboo, so that multiple bent line portions are stepped on upon walking so as to provide an effect of finger-pressure treatment of continuously stimulating the spots on the body suitable for acupuncture spread on the plantar region of the foot, and the lower surface of the sole is shaped like a round arc so as to correct posture and provide an excellent effect on exercises through walking.

[19] However, in the structures of the soles of the shoe shown in FIGs. 36 to 41, the air flow quantity between the sole and an inside of the shoe is not much so that the shoe has a bad smell due to the sweat of the foot when wearing the shoe for a long time.

[20] Further, in the structures of the soles of the shoe shown in FIGs. 36 to 41, the space for encasing an elastic means is inevitably positioned on the rear heel portion of the sole so as to limit on enhancing the cushioning with respect to the entire shoes.

Best Mode for Carrying Out the Invention

[69] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[70] FIG. 1 is a cross-sectional view illustrating an exemplary embodiment of a shoe according to the present invention, FIG. 2 is a bottom view of the present invention, and FIG. 3 is an exploded perspective bottom view illustrating main parts of the present invention.

[71] A shoe 1 includes an upper 2, a sole assembly 3 assembled with a lower part of the upper 2, and a rotation means 4 assembled with the sole assembly 3. The rotation means 4 includes an assembly part 5 depressed in the sole assembly 3 in contact with the plantar region of the foot, a shaft rod 6 formed in a center of the assembly part 5, an assembly tube 7 fixedly assembled with the shaft rod 6, a bearing 8 integrally formed with the assembly tube 7 in an inner ring 8a thereof, and a rotation body 9 assembled in an outer ring 8b of the bearing 8 and fixed with a ground-contact part 10 shaped like an arc and made of a material of rubber, or the like, on a lower part thereof. When the shaft rod 6 and the assembly tube 7 are fastened by means of a screw, or the like, there is a possibility of unfastening during rotating, so that a groove 6a is formed in the shaft rod 6 and an engaging protrusion 7a corresponding to the groove 6a is formed in the assembly tube 7 to be compulsorily fitted.

[72] Even though not shown in drawings, the assembly of the shaft rod 6 and the assembly tube 7 can be implemented with various configurations in a simple change in design, so that the various configurations would be determined to be same as that of the present invention. It is preferred that the rotation body 9 maintains its fixed state during the gait cycle, so that a stopper 11 is rotatably assembled with the sole assembly 3 and a groove 9a with which the stopper 11 is engaged is formed on the rotation body 9, thereby fixing the rotation body 9 during the gait cycle. One or two stoppers 11 are formed on the sole assembly 3, and it is preferred that the stopper includes a bracket 12 fixed on the sole assembly 3, a rotary shaft 13 assembled with the bracket 12, and a pivoting lever 14 assembled with the rotary shaft 13 and the end portion of the pivoting lever 14 being engaged with the groove 9a, wherein the rotary shaft 13 has two latching surfaces 13a adjacent at a predetermined angle and a leaf spring 15 of which both ends are latched by the bracket 12 is formed to alternatively contact with the both latching surfaces 13a, so as to control the rotation of the rotary shaft 13. The angle between both latching surfaces 13a is sufficient to which the pivoting lever 14 can be disengaged from the groove 9a. Further, the rotary shaft 13 can be integrally formed with the pivoting lever 14.

[73] The functional shoe 1 having the turning function as described above can be used for walking or turning through a simple operation of the stopper 11. Hereinafter, the use of the shoe according to the present invention and its operation will be described.

[74] When a wearer wishes to perform an exercise of twisting a body or enjoy a turning play with wearing the functional shoe 1, the wearer rotates the pivoting lever 14 engaged with the groove 9a formed on the rotation body 9 in a counterclockwise direction using a finger or a tool, such as a small driver, or the like, in a state of the sole assembly 3 facing upwardly. At this time, the rotary shaft 13 assembled with the pivoting lever 14 includes the adjacent latching surfaces 13a as shown in FIG. 5, so that the leaf spring 15 disposed to be in contact with one latching surface 13a in a state where the pivoting lever 14 being disengaged from the groove 9a comes into contact with the other latching surface 13 so as to fix the pivoting lever 14. Therefore, when the stopper is disengaged from the rotation body 9 as described above, the wearer can perform an exercise of twisting a waist while holding a wall or enjoy the turning play with twisting the body.

[75] Further, there is a concern that the wearer may fall down due to lose of their center of gravity by the rotation means 4 during the gait cycle with wearing the functional shoe 1. However, in the present invention, the rotation body 9 can be fixed by the stopper 11 so that safe walking can be guaranteed. That is, the pivoting lever 14 is rotated toward the rotation body 9 contrary to the above so that the end of the pivoting lever 14 is engaged with the groove 9a of the rotation body 9. At this time, as described above, the leaf spring 15 is in contact with the latching surface 13a to be fixed in a state where the pivoting lever 14 has been rotated toward the rotation body 9.

[76] FIGs. 6 to 25 illustrate a health shoe and each configuration thereof according to the present invention. Referring to FIG. 6, the health shoe having a mid-sole includes an upper 2 and the sole assembly, wherein the upper 2 includes an inner upper and an outer upper, and the sole assembly includes the mid-sole and an outsole. Referring to FIGs. 6 to 16, in the health shoe having the mid-sole according to the present invention, the mid-sole is completed through the way that first, an upper pad 110 and a lower pad 120 made of polyurethane are separately manufactured, and then the lower pad 120 is attached on a rear heel portion of the upper pad 110, so that the completed mid-sole is mounted within the shoe.

[77] Referring to FIGs. 7 to 9, in the mid-sole of the present invention, the entire lower pad 120 is made of soft polyurethane 130.

[78] Referring to FIGs. 10 to 12, in the mid-sole of the present invention, the lower pad

120 includes side spaces 132 at both sides of space of the rear heel portion of the upper pad 110 and a center portion of the lower pad 120 is made of soft polyurethane 130-1 to be attached at a center of the space of the rear heel portion of the upper pad 110.

[79] Referring to FIGs. 13 to 15, in the mid-sole of the present invention, the lower pad

120 includes the side spaces 132 at both sides of the space of the rear heel portion of the upper pad 110 and the center portion of the lower pad 120 is made of soft polyurethane 130-2 to be attached at the center of the space of the rear heel portion of the upper pad 110, and a central space 134 is formed at a center of the soft polyurethane 130-2.

[80] Referring to FIG.16, in the mid-sole of the present invention, the lower pad 120 includes the side spaces 132 at both sides of the space of the rear heel portion of the upper pad 110 and multiple springs 140 are mounted on the center portion of the lower pad 120 for the lower pad to be attached at the center of the space of the rear heel portion of the upper pad 110.

[81] The health shoe having the mid-sole of the present invention includes the upper 2, the sole assembly, and a footbed, wherein the sole assembly includes the mid-sole and the outsole, the rear heel of the outsole is shaped like a curved surface inclined to 0~40°with respect to the ground, and a rear heel of the mid-sole is shaped like an inclined curved surface, and a shank 29 having high resilience is mounted within an upper part of the mid-sole, so that a bottom engaging surface of the rear heel of the sole assembly is shaped like a heel of the foot and the curved surface formed in a front and rear direction along a movement trace of the heel of the foot with respect to the ankle joint during the gait cycle, thereby allowing the wearer to stamp on the ground during the gait cycle. In the shank 29 having high resilience inserted in the mid-sole, a plurality of slits 29a is formed extending through a particular position of a front portion to an end of the front portion of the shank so as to divide the front portion of the shank 29 into several equal parts, and ribs 29b shaped like a beed are formed for reinforcement in a center waist portion of the shank 29 in a front and rear direction, so that the bottom surface of the rear heel of the sole assembly is shaped like a heel of the foot and shaped like the curved surface formed in a front and rear direction along a movement trace of the heel of the foot with respect to the ankle joint during the gait cycle, thereby allowing the wearer to stamp on the ground during the gait cycle.

[82] In the health shoe having the mid-sole according to the present invention, the shank

29 having high resilience is inserted in the mid-sole, which preserves an original shape of the sole assembly and the shoe, renders the sole assembly easily bendable and deformable in height thereof during the gait cycle to return to its original shape, improves the safety in walking, and applies the repellent power during the disengagement from the ground, thereby securing light walking. The shank 29 inserted in the mid-sole may be made of any shape and material. However, it is preferred that the shank 29 is made of the material of polyvinyl chloride (P. V.C) and has a shape of a board patterning on an external shape and the curved surface shape of the mid-sole 3. Further, the front portion of the shank 29 having a relatively large bent angle during the gait cycle includes the slits 29a extending through the particular portion to the end of the front portion so as to divide the front portion of the shank 29 into multiple equal parts so that it allows the forefoot to be easily bent. Further, the center waist portion of the shank 29 includes the ribs 29b shaped like the beed for reinforcement in a front and rear direction so as to form multiple through holes 29c, thereby rendering the formation fluid to smoothly flow upon manufacturing the mid-sole 3.

[83] Referring to FIGs. 10 to 16, in the mid- sole having the rotation means for the health shoe having the stamping function according to the present invention, when the shoe is manufactured to include the mid-sole having the side spaces 132 in both sides of the lower pad 120, the center portion to which the soft polyurethane 130-1 and 130-2 are attached releases the impact with respect to the ground during the gait cycle and performs the second stamping. As shown in FIG. 17, in the mid-sole having the rotation means for the health shoe having the stamping function according to the present invention, when the shoe is manufactured to include the mid-sole having the side spaces 132 in both sides of the lower pad 120, the center portion to which soft spring 140 is assembled releases the impact with respect to the ground during the gait cycle and performs the second stamping.

[84] In the mid-sole having the rotation means for the health shoe having the stamping function according to the present invention, the rotation means 4 includes the assembly part 5 depressed in the mid-sole 3 in contact with the plantar region of the foot, the shaft rod 6 formed in the center of the assembly part 5, the assembly tube 7 fixed assembled to the shaft rod 6, the bearing 8 integrally formed with the assembly tube 7 in the inner ring 8a thereof, and the rotation body 9 assembled in the outer ring 8b of the bearing 8 and fixed with the ground-contact part 10 shaped like an arc and made of a material of rubber, or the like, on the lower part thereof. When the shaft rod 6 and the assembly tube 7 are fastened by means of a screw, or the like, there is a possibility of unfastening during the rotation, so that the groove 6a is formed in the shaft rod 6 and the engaging protrusion 7a corresponding to the groove 6a is formed in the assembly tube 7 to be compulsorily fitted.

[85] In the rotation means 4 of the present invention, it is preferred that the rotation body 9 maintains its fixed state during the gait cycle, so that the stopper 11 is rotatably assembled with the mid-sole 3 and the groove 9a with which the stopper 11 is engaged is formed on the rotation body 9, thereby fixing the rotation body 9 during the gait cycle.
