Description
- 1. Field of the Invention
- The present invention relates to a shoe, and more particularly, to a shock absorbing shoe which is able to absorb shocks applied to the foot of a wearer while walking or running.
- 2. Description of the Related Art
- A shoe is typically constructed of an upper member that protects the instep and ankle and a sole that protects the sole of a foot, improves walking and traveling abilities with an increased friction force to the ground and performs an absorbing action, the upper member being connected to the sole.
- In order to absorb shocks upon contacting to the ground through the above-mentioned sole, widely employed are air bags which have the sole made of a material with a superior expansion and contraction, i.e., a superior buffering ability, or which have the buffering function on the sole.
- However, in a case that the sole entirely made of a material with a superior buffering ability is used, it adds consumers' economic burden due to a cost increase. Especially, abrasion is easily occurred upon friction caused by a contact to the ground, this disables a long time wearing.
- Additionally, in case of employing the air bag, it has an advantage that the sole can be made of a material strong to abrasion. On the other hand, it is problematic in that the air bag is torn by a sharp object to thus run off air and resultantly can exhibit no buffering effect at all.
- Moreover, noises are generated from a torn part of the air bag whenever walking, this can make the user feel unpleasant.
- The present invention has been developed for the purpose of solving the foregoing problems and thus it is an object of the present invention to provide a shock absorbing shoe which absorbs shocks generated upon walking to the maximum by inserting a shock absorbing member with a rectangular cross sectional coil spring into the forefoot and heel portions of the sole of a foot and which allows walking and running without strain by a repulsive force of the spring.
- To achieve the above object, there is provided a shock absorbing shoe according to one aspect of the present invention, comprising: an upper member which wraps and protects the instep and ankle; a cushion member which is sutured to the upper member, improves a frictional force between the sole of a foot and the ground, and consists of a forefoot portion and a heel portion each having a recess of a predetermined depth; a buffering unit which is arranged in the respective recesses of the forefoot and heel portions of the cushion member for absorbing shocks while the wearer is walking or running; an air pumping unit which is arranged in the recess of the heel portion to perform an auxiliary buffering action and which supplies air onto the forefoot portion; and a bottom sole which is mounted on the upper part of the cushion member and to which the foot sole of the user is tightly attached.
- There is provided a shock absorbing shoe according to another aspect of the present invention, comprising: upper and lower caps which are symmetrical to each other and have a plurality of annular flanges projected, the annular flanges having insert grooves on the inside surfaces facing each other; and coil springs which integrally connects the upper and lower caps with both opposite ends being forcedly inserted into annular flange insert grooves of the upper and lower caps and have a predetermined elastic force.
- There is provided a shock absorbing shoe according to still another aspect of the present invention, which has a sole attached to the bottom portion of the shoe for protecting the foot sole and forming a friction with the ground, comprising: a cushion member which has an upper of the shoe attached thereto to form the shape of the shoe and a recess of a predetermined shape provided on the bottom surface; a friction member which is attached to the bottom surface of the cushion member for forming a friction with the ground; and a shock absorbing member which is arranged in the recess and has a predetermined recess formed between the cushion member and the friction member and several rectangular cross sectional coil springs elastically mounted between fixed caps.

FIGS. 4 to 6 are explanatory views showing a shock absorbing shoe according to a second embodiment of the present invention. FIGS. 7 to 9 are explanatory views showing a shock absorbing shoe according to a third embodiment of the present invention.
- Firstly, as shown in FIGS.1 to 3, the shock-absorbing shoe according to the first embodiment of the present invention will be described as follows.
- As shown therein, the shock-absorbing shoe is roughly divided into an
upper member 100, acushion member 110, abuffering unit 120, anair pumping unit 130 and a bottom sole 140. - The
upper member 100 is the region wrapping and protecting the instep and ankle, and is typically formed of a fabric or leather. - The
cushion member 110 is integrally formed with theupper member 100 by suturing and carries out the function of improving a frictional force between the sole of a foot and the ground. - On a
forefoot portion 111 and aheal portion 112 of thecushion member 110,recesses - To the
heel portion 112 of thecushion member 110, a projectingcushion 115 projecting relatively further than peripheral portions is integrally provided. The projectingcushion 115 is provided to theheel portion 112, which is the portion where largest shock is applied upon walking or running, in order to avoid a wearer from feeling by its foot the parts of thebuffering unit 120 to be described later upon walking or running so that the wearer does not feel uncomfortable. - The
buffering unit 120 is provided on therecesses forefoot portion 111 andheel portion 112 of thecushion member 110. They carry out the function of absorbing shocks while the wearer is walking or running. - In a detailed structure of this
buffering unit 120, upper andlower caps recesses annular flanges lower caps - On the
annular flanges insert grooves - Into the
insert grooves annular flanges coil springs 127 are forcedly inserted and fixed. By this forced insertion and fixing of thecoil springs 127, the upper andlower caps coil springs 127 are integrally connected to form one assembly. - Preferably, the
coil springs 127 are the ones that are excellent in elastic force and are not easily elastically deformed even by a long time, repetitive shock. - The
air pumping unit 130 is provided at therecess 114 formed on theheel portion 112 of thecushion member 110 and carries out an auxiliary buffering function along with the above-describedbuffering unit 120, especially, the function of supplying air to the sole of the wearer's foot by supplying air to theforefoot portion 111. - In a detailed structure of this
air pumping unit 130, on therecess 114 of theheel portion 112, anair pump 131 blasting air as being compressed by a shock from the upside, that is, a shock applied while the wearer is walking or running, is located approximately on the center between thecoil springs 127. - Additionally, an
air supply pipe 132 is prepared on at least one location for guiding the air blasted from theair pump 131 to therecess 113 of theforefoot portion 111. - Preferably, the
air supply pipe 132 is formed by forming aguide groove 133 on the upper surface of thecushion member 110 to a predetermined depth. But the present invention does not limited thereto and it is also possible to form theair supply pipe 132 as a separate part. - In order to supply air to the foot of the wearer in a state that air is guided to the
recess 113 of theforefoot portion 111 via theair supply pipe 132, a plurality of throughholes 141 are formed on the bottom sole 140 corresponding to theforefoot portion 111. - The shock-absorbing shoe thus constructed according to the present invention can acquire the shock absorbing effect as shocks applied to the foot sole while the wearer is walking or running are buffered by the
buffering unit 120, i.e., thecoil springs 127, prepared at therecesses cushion member 110. - In other words, the effect of buffering the shocks applied upon walking or running is exhibited as the
coil springs 127 are compressed, thereby preventing the foot of the wearer from getting strains applied thereto. - In addition thereto, since the
air pumping unit 130 is provided on therecess 114 formed on theheel portion 112 of thecushion member 110, that is, since there is provide theair pump 131 that exhibits the buffering effect by blasting air while compressed when a shock is applied, a more effective buffering effect can be acquired. - Furthermore, the air compressed upon operation of the
air pumping unit 130 is guided to therecess 113 of theforefoot portion 111 via theair supply pipe 132 and simultaneously introduced into the shoe via the throughholes 141 formed on the bottom sole 140 at the position corresponding to theforefoot portion 111. By this, the foot of the wearer can be cooled down and the generation of sweat caused by a long time wearing can be prevented. - Next, as shown in FIGS.4 to 6, the shock absorbing shoe according to the second embodiment of the present invention will be described.
- As shown therein, the shock absorbing shoe is roughly divided into an
upper cap 210, alower cap 220 andcoil springs 230. - The upper and
lower caps annular flanges annular flanges grooves - The
coil springs 230 are arranged between the upper andlower caps insert grooves annular flanges lower caps - In other words, the upper and
lower caps coil springs 230 are integrally connected directly via thecoil springs 230 to form one assembly. - The
coil springs 230 of such a type may be ones having a circular cross sectional shape, more preferably, rectangular crosssectional coil springs 230 which are less deformable and are highly elastic. - Between the upper and
lower caps coil spring 230 is mounted. - When such a space region is generated, there is a possibility that noises occurring upon a buffering action through the
coil springs 230 are emitted to the outside. Thus, in order to prevent this emission and double the buffering effect along with thecoil springs 230, it is preferable that anauxiliary buffering body 240 is sandwiched between the upper andlower caps coil springs 230. - Preferably, the
auxiliary buffering body 240 is formed of a material having an elastic force, that is, a rubber or sponge. - In the shock absorbing shoe of this invention, in a state that the coil springs230 are sandwiched between the upper and
lower caps auxiliary buffering body 240 being sandwiched therebetween, that is, in a state that one assembly is formed, the assembly is positioned on therecess 113 formed on theforefoot portion 111 andheel portion 112 of the bottom surface of thecushion member 110. - According to its purpose of use, the
auxiliary buffering body 240 may be selectively sandwiched between theforefoot portion 111 and theheel portion 112. - Consequently, as the coil springs230 and the
auxiliary buffering body 240 carry out a buffering action while the user is walking or running, a burden caused by a shock applied to the user's foot can be alleviated. - Since the coil springs230 sandwiched between the upper and
lower caps insert grooves annular flanges lower caps lower caps - That is to say, it is made possible to maintain a mutual firm assembly state.
- Meanwhile, because the
auxiliary buffering body 240 sandwiched between the upper andlower caps auxiliary buffering body 240 exhibits the effect of blocking the space region between the upper andlower caps - Next, referring to FIGS.7 to 9, the shock absorbing shoe according to the third embodiment is of the present invention will be described.
- As shown therein, the
shock absorbing shoe 300 is comprised of anupper member 310 wrapping and protecting the instep and ankle and acushion member 320 increasing a frictional force between the sole of a foot and the ground upon walking. - The
cushion member 320 is provided with an inner sole which is placed on the surface of the cushion member, which is compressively bonded to theupper member 310 with a bond or coupled thereto by sewing so as to absorb shocks and achieve a stable coupling state and which offers wearing stability, air permeability and absorptivity, but a detailed description and illustration therefore will be omitted. - And, the
cushion member 320 has arecess 324 of a predetermined shape concavely formed on theforefoot portion 321 andheel portion 322 of the bottom surface thereof. Theheel portion 322 is pierced to form through holes penetrating therecess 324 from the sides. - Into the
recess 324, ashock absorbing member 340 having the same shape and height as the recess is inserted and fixed. In theshock absorbing member 340, fixedcaps 343 are covered onto the upper and lower parts of rectangular cross sectional coil springs 346, awire 344 passes through the center of the fixedcaps 343 and both ends of thewire 344 are fixed to the fixedcaps 343 by welding or riveting. At this time, the rectangular cross sectional coil springs 346 are compressed to a predetermined state and fixed so that it can hold an elastic force suitable for absorbing and alleviating shocks generated from the sole of a shoe during walking or running. - At the center of the fixed
caps 343 fixing thewire 344 passing through the center of the rectangular cross sectional coil springs 346, mountinggrooves 342 for fixing thewire 344 are formed concave so that the fixed end of thewire 344 cannot be projected to the outside. - A compression state of the rectangular cross sectional coil springs346 mounted between the
fixed caps 343 is differently set according to whether they are mounted on theheel portion 322 or on theforefoot portion 321. It means that the fixedcaps 343 are arranged on afixed plate 341 having the same shape as therecess 324 formed on the bottom of thecushion member 320, taking a shock distribution generated by a human body during walking or running into account. - Another fixed
plate 341 is placed above the fixedcaps 343 mounted on the fixedplate 341. In this state, several fixedcaps 343 are welded or inserted into fixed protuberances projected from the fixed plates so that they cannot move between thefixed plates 341. - With the
shock absorbing member 340 of the above construction being inserted and fixed into therecess 324 of thecushion member 320, afriction member 330 made of rubber with high elasticity is attached to the bottom surface of thecushion member 320 andshock absorbing member 340 to achieve a friction to the ground. Being inserted and fixed into therecess 324 of thecushion member 320. - Further, a cushion material of a transparent type is inserted into a the through hole perforated in the heel region of the
cushion member 320, to thus form atransparent window portion 323 capable of confirming theshock absorbing member 340 mounted in therecess 324. - In the shock absorbing shoe thus constructed of this invention, the
heel portion 322 is firstly contacted to the ground upon walking or running, then the foot sole is contacted, and then theforefoot portion 321 is contacted. When theheel portion 322 is contacted, theshock absorbing member 340 absorbs shocks concentrated on theheel portion 322 as shown in FIG. 4. That is, shocks applied to a certain compressed rectangular cross sectional coil springs 346 are firstly absorbed. Shocks exceeding a compression state are secondly absorbed as the rectangular cross sectional coil springs 346 are further compressed. - In other words, as illustrated in FIG. 4, a concentrated load passing through the
cushion member 320 is firstly transferred to the fixedplate 341 via theheel portion 322, and the concentrated load transferred to the fixedplate 341 is dispersed to the rectangular cross sectional coil springs 346 via the fixedcaps 343 arranged and fixed at their respective position of the fixedplate 341. Next, the dispersed load is firstly absorbed in the rectangular cross sectional coil springs 346 that is mounted in a compressed state, and shocks exceeding the compressed state are transferred to the rectangular cross sectional coil springs 346. At this time, the second compression of the compressed rectangular cross sectional coil springs 346 is performed onto the rectangular cross sectional coil springs 346 over theheel portion 322, thereby allowing all of the springs to absorb the dispersed and transferred load. - Hence, the concentrated load generated~upon contacting the
heel portion 322 onto the ground is dispersed and transferred to each of the rectangular cross sectional coil springs 346 in the process of transferring to theshock absorbing member 340 of this invention. By this, each of the rectangular cross sectional coil springs 346 receives a load of a dispersed state and compensates the shock caused by the dispersed load with a stress against the load, thereby drastically reducing the shock transferred to the heel and knee joints of the user. - And, according to a moving state of the foot, when the user is moving by the foot sole and the
forefoot portion 321, theshock absorbing member 340 mounted to theforefoot portion 321 in a first compression state is secondly compressed with a concentrated load. And, the rectangular cross sectional coil springs 346 of theshock absorbing member 340 located in theheel portion 322 forms a repulsive force to provide elasticity to the user's foot. - The rectangular cross sectional coil springs346 of the
shock absorbing member 340, which are compressed in theforefoot portion 321 by a continuous movement of the foot, transfers to the user a repulsive force corresponding to the compression state as soon as the foot is released from the ground. Thus, while the user is walking or running, the shock caused by its weight is absorbed in theshoe 300. Besides, the repulsive force corresponding to the elasticity for compression is transferred to the foot, thereby enabling the user to walk or run without strain. - The rectangular cross sectional coil springs346 contracting and repulsing in the
shock absorbing member 340 as seen from above are mounted between thefixed caps 343 and around thewire 344. In this state, since the fixedcaps 343 are located on the fixedplate 341 in a fixed state, a concentrated load is transferred via the fixedplate 341 made of a high surface strength material when theheel portion 322 is contacted to the ground, thereby achieving a stable compressing action. Moreover, since the rectangular cross sectional coil springs 346 have a cross section of a flat, rectangular shape, whatever direction the concentrated load may be applied from, the rectangular cross sectional coil springs 346 achieve a stable compression state by means of the fixedplate 341. - Furthermore, since the installation state of the
shock absorbing member 340 and the elastic state of the rectangular cross sectional coil springs 346 can be visually confirmed through thetransparent window portion 323 formed on theheel portion 322 of thecushion member 320, this improves the user's certainty of the functionality. - As seen from above, according to the shock absorbing shoe according to the present invention, a mutual complementary buffering effect is exhibited by the coil springs and the auxiliary buffering body and so on, thus doubling the shock absorbing effect.
- Therefore, there is no strain given to the knee or joints of the user, so the convenience of use and marketability can be enhanced.
