Abstract
The present invention relates to shock absorbing shoes with improved assembly and operational performance. More specifically, there is provided a shock absorbing shoe comprising: an outer sole; an upper sole which is arranged on top of the outer sole and has a guide portion; a backing member which includes a first backing body connected to the outer sole, and a second backing body that is connected to the upper sole and has a guidance element corresponding the guide portion; an elastic member arranged between the first backing body and the second backing body of the backing member; and a supporting member connected to the first and second backing bodies of the backing member, the supporting member being movable upward and downward through the guide portion and the guidance element of the second backing body. According to the shock absorbing shoes with improved assembly and operational performance, the supporting member serves in particular to prevent the separation and isolation of the elastic member to thus improve durability of the shock absorbing shoe; and when the supporting member makes a relative movement (i.e. the upward and downward movements) at the time of the compression and restitution following the compression of the elastic member during walking, the guide portion of the upper sole as well as the guidance element of the second backing body receive and guide the relative movement of the supporting member, thereby ensuring operational reliability of the elastic member and the supporting member, respectively. Further, coupling the elastic member and the supporting member that secures the elastic member from both top and bottom sides can be achieved easily and conveniently by means of the supporting member, which in turn results in easier assembly, shortened assembly time and increased productivity, compared to those conventional shock absorbing shoes. Moreover, since all components can be taken apart easily by disassembling the supporting member only, the maintenance work can be facilitated and the work efficiency can be enhanced.

Hereinbelow, a shock absorbing shoe with improved assembly and operational performance according to the present invention will be described in detail with reference to the accompanying drawings.
As shown in Figs. 1 through 7, the shock absorbing shoe with improved assembly and operational performance according to the present invention includes:
an outsole 10; an upper sole 20 which is arranged on top of the outsole 10 and has a guide portion 21; a support unit 30 which includes a first support body 30A that is connected to the outsole 10, and a second support body 30B that is connected to the upper sole 20 and has a guide part 33 corresponding to the guide portion 21; an elastic member 40 which is arranged between the first and second support bodies 30A and 30B of the support unit 30; and a supporting member 50 which is connected to the first and second support bodies 30A and 30B of the support unit 30 and moves upward and downward through both the guide portion 21 and the guide part 33 of the second support body 30B.
As shown in Figs. 1 through 4, in the shock absorbing shoe with improved assembly performance and improved operational performance according to the present invention, the outsole 10 is configured as follows.
The upper surface of the outsole 10 is firmly bonded to the lower surface of the first support body 30A of the support unit 30 using a bonding agent or a strong adhesive. This outsole 10 makes direct contact with the ground surface.
Here, the lower surface of the outsole 10 is a part that comes into direct contact with the ground surface so that, in order to absorb shocks and prevent slipping when the lower surface of the outsole is brought into contact with the ground surface. For this reason, it is preferred that the outsole be formed using an elastic material, such as elastomer, polyurethane or rubber.
Further, in order to improve the shock absorbing and slip prevention function, the outsole 10 is configured as follows using the above-mentioned elastic material.
That is, studs 11 are formed on the lower surface of the outsole in such a way that a plurality of protrusions or a plurality of prominences and depressions are formed on the lower surface of the outsole. Accordingly, the outsole has an improved shock absorbing function and an improved slip preventing function.
Further, the outsole 10 has an integrated structure in which the front sole and the heel of the outsole are integrated into a single structure.
The above-mentioned integrated structure of the outsole 10 can solve the problem that has been experienced with a separated outsole in which the front sole becomes separated from the heel so that a user may fall over a stone or a protruding object while walking.
Further, a stone or a protruding object may insert itself between the front sole and the heel of the separated outsole so that the stone or the protruding object causes the user discomfort while walking. However, the integrated structure of the outsole 10 of the present invention can solve the above-mentioned problem.
As shown in Figs. 1 through 4, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the upper sole 20 is configured as follows.
The upper sole is arranged on top of the outsole 10. The lower surface of the upper sole is firmly bonded to the upper surface of the second support body 30B of the support unit 30 using a bonding agent or a strong adhesive so that the sole of a user or an insole is laid on the upper surface of the upper sole.
Further, a shoe body SB is connected to the top of the upper sole 20 and covers the instep of the user, thereby safely protecting the instep of the user when the user walks or exercises.
In the upper sole 20 of the present invention, four guide portions 21 having a grooved shape are formed at four locations of a heel part at which four elastic members 40 are arranged.
Each of the four guide portions 21 is arranged inside an associated elastic member 40 so that, when the supporting member 50 that is combined with the first and second support bodies 30A and 30B of the support unit 30 moves upward and downward, the guide portion 21 functions to guide the upper portion of the supporting member 50.
In other words, when the user walks and the elastic member 40 is repeatedly compressed and reverts back to its original shape after being compressed, the guide portion 21 can guide the movement of the supporting member 50 that moves upward and downward relative to the elastic member 40, thereby realizing improved operational reliability of the supporting member 50.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the support unit 30 is configured as follows.
The support unit 30 is mounted to the upper surface of the outsole 10 and to the lower surface of the upper sole 20 and is combined with the elastic member 40, thereby supporting the elastic member 40 at a desired location.
The support unit 30 of the present invention includes the first and second support bodies 30A and 30B.
The first support body 30A is held in the upper surface of the outsole 10. The second support body 30B is held in the lower surface of the upper sole 20.
Further, the guide part 33 having a hole shape is formed in the second support body 30B so that the guide part 33 corresponds to the guide portion 21 of the upper sole 20.
When the supporting member 50 moves upward and downward, the guide part 33 guides the movement of the supporting member 50, thereby realizing the improved operational reliability of the supporting member 50.
Further, in each of the first and second support bodies 30A and 30B, the annular protrusions 32 are formed at locations at which the elastic members 40 are arranged. A depressed seat 31 is formed inside each of the annular protrusions 32 so as to hold the elastic member 40 therein.
Further, in the support unit 30 of the present invention, first and second holding bodies 35 and 37 having a disc shape are mounted to the depressed seats 31 of the first and second support bodies 30A and 30B by fitting or bonding.
The first holding body 35 is combined with the lower end of the elastic member 40 and the second holding body 37 is combined with the upper end of the elastic member 40.
Respective annular rims 35d and 37d are formed along the edges of the first and second holding bodies 35 and 37, and respective seat depressions 35e and 37e are formed inside the rims 35d and 37d.
Further, fitting protrusions 35c and 37c are formed in the centers of the respective seat depressions 35e and 37e so that the elastic member 40 can be held by the first and second holding bodies 35 and 37 as follows.
When the opposite ends of the elastic member 40 are fitted into the respective seat depressions 35e and 37e, the outer circumferential surfaces of the opposite ends of the elastic member 40 come into contact with the inner circumferential surfaces of the rims 35d 37d.
Further, the inner circumferential surfaces of the opposite ends of the elastic member 40 come into contact with the outer circumferential surfaces of the fitting protrusions 35c and 37c. Accordingly, the upper and lower ends of the elastic member 40 can be firmly held by the rims 35d and 37d, the seat depressions 35e and 37e, and the fitting protrusions 35c and 37c so that it is possible to prevent the elements from being removed or separated from each other.
Here, the elastic member 40 may be combined with the first and second holding bodies 35 and 37 through fitting or bonding.
However, to realize easy assembly of the elements based on the structural characteristics of the first and second holding bodies 35 and 37, it is preferred that the elastic member 40 be fitted into the first and second holding bodies 35 and 37.
Further, a protruding spacer part 36 is formed on the lower surface of the fitting protrusion 37c of the second holding body 37 so that, when the elastic member 40 is compressed, the lower surface of the protruding spacer part 36 comes into contact with the upper surface of the first holding body 35.
The protruding spacer part 36 in the above state can space the first and second holding bodies 35 and 37 away from each other by a predetermined gap so that it is possible to prevent the turns of a coil spring 41 that is used as the elastic member 40 from coming into contact with each other or from striking each other when the user walks, thereby preventing the elastic member 40 from being broken by shocks.
In Figs. 2, 3 and 6, the protruding spacer part 36 is formed on the lower surface of the fitting protrusion 37c of the second holding body 37.
However, it should be understood that although it is not shown in the accompanying drawings, the protruding spacer part 36 may be formed on the upper surface of the fitting protrusion 35c of the first holding body 35 so that, when the elastic member is compressed, the protruding spacer part 36 comes into contact with the lower surface of the fitting protrusion of the second holding body 37 and spaces the first and second holding bodies 35 and 37 away from each other by a predetermined gap, thereby performing the same operational function as that described above.
Further, the second holding body 37 has a corresponding guide part 37a, which is formed in the second holding body 37 in such a way that the corresponding guide part 37a is defined inside the protruding spacer part 36 of the second holding body 37.
In other words, the corresponding guide part 37a is formed inside the protruding spacer part 36 so as to correspond to the guide part 33 of the second support body 30B so that, when the supporting member 50 moves upward and downward, the corresponding guide part 37a can guide the movement of the supporting member 50, thereby realizing improved operational reliability of the supporting member 50.
Here, the guide portion 21 of the upper sole 20, the guide part 33 of the second support body 30B and the corresponding guide part 37a of the second holding body 37 communicate with each other so that the supporting member 50 can move upward and downward thanks to the above-mentioned elements which are all in communication with each other.
In the above state, the guide portion 21, the guide part 33 and the corresponding guide part 37a allow the supporting member 50 to reliably move without interfering with the other elements.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the configuration of the elastic member 40 is as follows.
The elastic member is placed between the first and second support bodies 30A and 30B of the support unit 30 so that the elastic element can absorb and attenuate shocks that are applied to the heel of the user when the user walks, thereby relieving the feet of the user from fatigue and allowing the user to walk in comfort.
Here, a coil spring 41 is used as the elastic member 40 of the present invention, in which the lower and upper ends of the coil spring 41 are combined with the first and second holding bodies 35 and 37, respectively.
In the above state, the coil spring 41 is firmly held by the inner circumferential surfaces of the rims 35d and 37d of the respective holding bodies 35 and 37, and by the seat depressions 35e and 37e, and by the fitting protrusions 35c and 37c.
Accordingly, when a user wearing the shoes having the coil springs 41 walks, exercises or is working, the coil springs perform their functions as follows.
When a load formed by the weight of the user is applied to the ground surface through the shoes, a reactive shock is applied upward from the ground surface to the user. In the above state, the coil springs 41 elastically absorb and attenuate the shock.
Accordingly, even when the user continuously walks, exercises or is working for a lengthy period of time, the coil springs can efficiently absorb and attenuate the shocks that are applied to the feet and body of the user, thereby relieving the feet and the body from fatigue and realizing the healthful function of the shoes and allowing the user to feel comfortable.
Further, it is preferred that the coil springs 41 have a square cross-section.
When the coil springs 41 are compressed by the load of the user, the coil springs that are arranged in the shoe may strike each other.
Here, when coil springs 41 having a circular cross-section are used, the outer circumferential surfaces of the coil springs 41 may come into contact with each other, so that their striking each other may cause them to easily break.
However, when the coil springs 41 having a square cross-section are used in the shoe and are compressed by the load, the springs 41 come into contact with each other along the flat surfaces thereof, thereby minimizing the breakage of the springs even should the springs strike each other.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the supporting member 50 is configured as follows.
The supporting member is connected to the first and second support bodies 30A and 30B of the support unit 30 at a location between the two support bodies so that, when the elastic member 40 repeats elastic deformation when the user walks, the supporting member can prevent removal or separation of the elastic member 40.
In other words, the supporting member 50 of the present invention is coupled to the first and second holding bodies 35 and 37 that are combined with the first and second support bodies 30A and 30B, respectively.
In the above state, the lower end of the supporting member 50 is combined with the first holding body 35.
The upper end of the supporting member 50 is combined with the second holding body 37 so that the supporting member can repeatedly move upward and downward when the user walks.
Described in detail, the supporting member 50 includes a head 51 that is formed in the upper end of the supporting member, a shank 53 that extends downward from the lower surface of the head 51, and a locking part 55 that is formed in the lower end of the shank 53.
Here, the locking part 55 is connected to the first holding body 35 by a holding means FM.
The head 51 is seated in the corresponding guide part 37a of the second holding body 37 so that, when the elastic member 40 performs an elastic action, the head 51 can prevent the removal or separation of the supporting member 50 from the second holding body 37. In the above state, the head 51 cooperates with a stopping means SP.
The construction for combining the supporting member 50 and the first holding body 35 with each other using the holding means FM will be described hereinbelow with reference to Figs.
2 through 6.
A through hole 35b is formed through the center of the first holding body 35.
Further, seat grooves 35a are symmetrically formed in the lower surface of the first holding body on opposite sides of the through hole 35b.
Further, an insert hole 55a is formed in the locking part 55 that is provided in the lower end of the supporting member 50.
Further, a locking pin 60 is provided. To combine the supporting member and the first holding body with each other, the locking pin 60 is inserted into the insert hole 55a after the supporting member 50 is inserted into the through hole 35b.
Thereafter, the locking pin 60 is seated in the seat grooves 35a.
When the lower end of the supporting member 50 is combined with the first holding body 35, the holding means FM performs the following function.
The holding means FM can more easily and efficiently combine the supporting member 50 and the first holding body 35 with each other.
Further, the assembled holding means can prevent the supporting member 50 and the first holding body 35 from being released from each other by vibrations or shocks that may be applied both to the supporting member and to the first holding body when a user wearing the shoes walks.
To realize the above-mentioned function of the holding means FM, the locking pin 60 of the holding means FM is seated in the seat grooves 35a of the first holding body 35 after the locking pin 60 has been inserted into the insert hole 55a of the supporting member 50 so that the locking pin 60 can hold and prevent rotation of the supporting member 50 irrespective of vibrations or shocks that are applied to the supporting member.
Fig. 7 illustrates a modification of the holding means FM.
In the modification, an internal thread 35f is formed on the inner circumferential surface of the through hole 35b of the first holding body 35, and an external thread 55b is formed around the outer circumferential surface of the locking part 55 of the supporting member 50 so that the supporting member 50 can be tightened to the holding body 35 by rotating the supporting member relative to the holding body.
In the above state, it is preferred that the upper surface of the head 51 of the supporting member 50 be recessed to form a straight recess, a cross recess or a combined recess so that the supporting member and the first holding body can be easily assembled and disassembled using a tool.
Hereinbelow, the structure for combining the supporting member 50 with the second holding body 37 using the stopping means SP will be described with reference to Figs. 2 through 7.
A stopper 37b is formed in the lower part of the corresponding guide part 37a of the second holding body 37.
That is, the stopper 37b is formed on the lower surface of the protruding spacer part 36 of the second holding body 37.
Further, a shank passing hole 37f is formed through the center of the protruding spacer part 36. Here, the diameter of the shank passing hole 37f is less than inner diameter of the corresponding guide part 37a but is greater than that of the shank 53.
The stopper 37b is formed in the shape of a step at an area around the shank passing hole 37f.
Accordingly, when the shank 53 of the supporting member 50 passes through the shank passing hole 37f, the shank 53 can move through the shank passing hole 37f when the elastic member 40 is compressed and reverts back to its original shape after yI ~
having been compressed.
Further, when the elastic member 40 fully extends and completely reverts back to its original shape, the head 51 that is connected to the upper end of the shank 53 of the supporting member 50 can be caught and held by the stopper 37b.
Therefore, it is possible to prevent removal or separation of the supporting member 50 from the second holding body 37.
Although the shock absorbing shoe with improved assembly and operational performance of the present invention has been disclosed based on specific shapes and directions in the above description, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.

Hereinbelow, a shock absorbing shoe with improved assembly and operational performance according to the present invention will be described in detail with reference to the accompanying drawings.
As shown in Figs. 1 through 7, the shock absorbing shoe with improved assembly and operational performance according to the present invention includes:
an outsole 10; an upper sole 20 which is arranged on top of the outsole 10 and has a guide portion 21; a support unit 30 which includes a first support body 30A that is connected to the outsole 10, and a second support body 30B that is connected to the upper sole 20 and has a guide part 33 corresponding to the guide portion 21; an elastic member 40 which is arranged between the first and second support bodies 30A and 30B of the support unit 30; and a supporting member 50 which is connected to the first and second support bodies 30A and 30B of the support unit 30 and moves upward and downward through both the guide portion 21 and the guide part 33 of the second support body 30B.
As shown in Figs. 1 through 4, in the shock absorbing shoe with improved assembly performance and improved operational performance according to the present invention, the outsole 10 is configured as follows.
The upper surface of the outsole 10 is firmly bonded to the lower surface of the first support body 30A of the support unit 30 using a bonding agent or a strong adhesive. This outsole 10 makes direct contact with the ground surface.
Here, the lower surface of the outsole 10 is a part that comes into direct contact with the ground surface so that, in order to absorb shocks and prevent slipping when the lower surface of the outsole is brought into contact with the ground surface. For this reason, it is preferred that the outsole be formed using an elastic material, such as elastomer, polyurethane or rubber.
Further, in order to improve the shock absorbing and slip prevention function, the outsole 10 is configured as follows using the above-mentioned elastic material.
That is, studs 11 are formed on the lower surface of the outsole in such a way that a plurality of protrusions or a plurality of prominences and depressions are formed on the lower surface of the outsole. Accordingly, the outsole has an improved shock absorbing function and an improved slip preventing function.
Further, the outsole 10 has an integrated structure in which the front sole and the heel of the outsole are integrated into a single structure.
The above-mentioned integrated structure of the outsole 10 can solve the problem that has been experienced with a separated outsole in which the front sole becomes separated from the heel so that a user may fall over a stone or a protruding object while walking.
Further, a stone or a protruding object may insert itself between the front sole and the heel of the separated outsole so that the stone or the protruding object causes the user discomfort while walking. However, the integrated structure of the outsole 10 of the present invention can solve the above-mentioned problem.
As shown in Figs. 1 through 4, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the upper sole 20 is configured as follows.
The upper sole is arranged on top of the outsole 10. The lower surface of the upper sole is firmly bonded to the upper surface of the second support body 30B of the support unit 30 using a bonding agent or a strong adhesive so that the sole of a user or an insole is laid on the upper surface of the upper sole.
Further, a shoe body SB is connected to the top of the upper sole 20 and covers the instep of the user, thereby safely protecting the instep of the user when the user walks or exercises.
In the upper sole 20 of the present invention, four guide portions 21 having a grooved shape are formed at four locations of a heel part at which four elastic members 40 are arranged.
Each of the four guide portions 21 is arranged inside an associated elastic member 40 so that, when the supporting member 50 that is combined with the first and second support bodies 30A and 30B of the support unit 30 moves upward and downward, the guide portion 21 functions to guide the upper portion of the supporting member 50.
In other words, when the user walks and the elastic member 40 is repeatedly compressed and reverts back to its original shape after being compressed, the guide portion 21 can guide the movement of the supporting member 50 that moves upward and downward relative to the elastic member 40, thereby realizing improved operational reliability of the supporting member 50.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the support unit 30 is configured as follows.
The support unit 30 is mounted to the upper surface of the outsole 10 and to the lower surface of the upper sole 20 and is combined with the elastic member 40, thereby supporting the elastic member 40 at a desired location.
The support unit 30 of the present invention includes the first and second support bodies 30A and 30B.
The first support body 30A is held in the upper surface of the outsole 10. The second support body 30B is held in the lower surface of the upper sole 20.
Further, the guide part 33 having a hole shape is formed in the second support body 30B so that the guide part 33 corresponds to the guide portion 21 of the upper sole 20.
When the supporting member 50 moves upward and downward, the guide part 33 guides the movement of the supporting member 50, thereby realizing the improved operational reliability of the supporting member 50.
Further, in each of the first and second support bodies 30A and 30B, the annular protrusions 32 are formed at locations at which the elastic members 40 are arranged. A depressed seat 31 is formed inside each of the annular protrusions 32 so as to hold the elastic member 40 therein.
Further, in the support unit 30 of the present invention, first and second holding bodies 35 and 37 having a disc shape are mounted to the depressed seats 31 of the first and second support bodies 30A and 30B by fitting or bonding.
The first holding body 35 is combined with the lower end of the elastic member 40 and the second holding body 37 is combined with the upper end of the elastic member 40.
Respective annular rims 35d and 37d are formed along the edges of the first and second holding bodies 35 and 37, and respective seat depressions 35e and 37e are formed inside the rims 35d and 37d.
Further, fitting protrusions 35c and 37c are formed in the centers of the respective seat depressions 35e and 37e so that the elastic member 40 can be held by the first and second holding bodies 35 and 37 as follows.
When the opposite ends of the elastic member 40 are fitted into the respective seat depressions 35e and 37e, the outer circumferential surfaces of the opposite ends of the elastic member 40 come into contact with the inner circumferential surfaces of the rims 35d 37d.
Further, the inner circumferential surfaces of the opposite ends of the elastic member 40 come into contact with the outer circumferential surfaces of the fitting protrusions 35c and 37c. Accordingly, the upper and lower ends of the elastic member 40 can be firmly held by the rims 35d and 37d, the seat depressions 35e and 37e, and the fitting protrusions 35c and 37c so that it is possible to prevent the elements from being removed or separated from each other.
Here, the elastic member 40 may be combined with the first and second holding bodies 35 and 37 through fitting or bonding.
However, to realize easy assembly of the elements based on the structural characteristics of the first and second holding bodies 35 and 37, it is preferred that the elastic member 40 be fitted into the first and second holding bodies 35 and 37.
Further, a protruding spacer part 36 is formed on the lower surface of the fitting protrusion 37c of the second holding body 37 so that, when the elastic member 40 is compressed, the lower surface of the protruding spacer part 36 comes into contact with the upper surface of the first holding body 35.
The protruding spacer part 36 in the above state can space the first and second holding bodies 35 and 37 away from each other by a predetermined gap so that it is possible to prevent the turns of a coil spring 41 that is used as the elastic member 40 from coming into contact with each other or from striking each other when the user walks, thereby preventing the elastic member 40 from being broken by shocks.
In Figs. 2, 3 and 6, the protruding spacer part 36 is formed on the lower surface of the fitting protrusion 37c of the second holding body 37.
However, it should be understood that although it is not shown in the accompanying drawings, the protruding spacer part 36 may be formed on the upper surface of the fitting protrusion 35c of the first holding body 35 so that, when the elastic member is compressed, the protruding spacer part 36 comes into contact with the lower surface of the fitting protrusion of the second holding body 37 and spaces the first and second holding bodies 35 and 37 away from each other by a predetermined gap, thereby performing the same operational function as that described above.
Further, the second holding body 37 has a corresponding guide part 37a, which is formed in the second holding body 37 in such a way that the corresponding guide part 37a is defined inside the protruding spacer part 36 of the second holding body 37.
In other words, the corresponding guide part 37a is formed inside the protruding spacer part 36 so as to correspond to the guide part 33 of the second support body 30B so that, when the supporting member 50 moves upward and downward, the corresponding guide part 37a can guide the movement of the supporting member 50, thereby realizing improved operational reliability of the supporting member 50.
Here, the guide portion 21 of the upper sole 20, the guide part 33 of the second support body 30B and the corresponding guide part 37a of the second holding body 37 communicate with each other so that the supporting member 50 can move upward and downward thanks to the above-mentioned elements which are all in communication with each other.
In the above state, the guide portion 21, the guide part 33 and the corresponding guide part 37a allow the supporting member 50 to reliably move without interfering with the other elements.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the configuration of the elastic member 40 is as follows.
The elastic member is placed between the first and second support bodies 30A and 30B of the support unit 30 so that the elastic element can absorb and attenuate shocks that are applied to the heel of the user when the user walks, thereby relieving the feet of the user from fatigue and allowing the user to walk in comfort.
Here, a coil spring 41 is used as the elastic member 40 of the present invention, in which the lower and upper ends of the coil spring 41 are combined with the first and second holding bodies 35 and 37, respectively.
In the above state, the coil spring 41 is firmly held by the inner circumferential surfaces of the rims 35d and 37d of the respective holding bodies 35 and 37, and by the seat depressions 35e and 37e, and by the fitting protrusions 35c and 37c.
Accordingly, when a user wearing the shoes having the coil springs 41 walks, exercises or is working, the coil springs perform their functions as follows.
When a load formed by the weight of the user is applied to the ground surface through the shoes, a reactive shock is applied upward from the ground surface to the user. In the above state, the coil springs 41 elastically absorb and attenuate the shock.
Accordingly, even when the user continuously walks, exercises or is working for a lengthy period of time, the coil springs can efficiently absorb and attenuate the shocks that are applied to the feet and body of the user, thereby relieving the feet and the body from fatigue and realizing the healthful function of the shoes and allowing the user to feel comfortable.
Further, it is preferred that the coil springs 41 have a square cross-section.
When the coil springs 41 are compressed by the load of the user, the coil springs that are arranged in the shoe may strike each other.
Here, when coil springs 41 having a circular cross-section are used, the outer circumferential surfaces of the coil springs 41 may come into contact with each other, so that their striking each other may cause them to easily break.
However, when the coil springs 41 having a square cross-section are used in the shoe and are compressed by the load, the springs 41 come into contact with each other along the flat surfaces thereof, thereby minimizing the breakage of the springs even should the springs strike each other.
As shown in Figs. 1 through 6, in the shock absorbing shoe with improved assembly and operational performance according to the present invention, the supporting member 50 is configured as follows.
The supporting member is connected to the first and second support bodies 30A and 30B of the support unit 30 at a location between the two support bodies so that, when the elastic member 40 repeats elastic deformation when the user walks, the supporting member can prevent removal or separation of the elastic member 40.
In other words, the supporting member 50 of the present invention is coupled to the first and second holding bodies 35 and 37 that are combined with the first and second support bodies 30A and 30B, respectively.
In the above state, the lower end of the supporting member 50 is combined with the first holding body 35.
The upper end of the supporting member 50 is combined with the second holding body 37 so that the supporting member can repeatedly move upward and downward when the user walks.
Described in detail, the supporting member 50 includes a head 51 that is formed in the upper end of the supporting member, a shank 53 that extends downward from the lower surface of the head 51, and a locking part 55 that is formed in the lower end of the shank 53.
Here, the locking part 55 is connected to the first holding body 35 by a holding means FM.
The head 51 is seated in the corresponding guide part 37a of the second holding body 37 so that, when the elastic member 40 performs an elastic action, the head 51 can prevent the removal or separation of the supporting member 50 from the second holding body 37. In the above state, the head 51 cooperates with a stopping means SP.
The construction for combining the supporting member 50 and the first holding body 35 with each other using the holding means FM will be described hereinbelow with reference to Figs.
2 through 6.
A through hole 35b is formed through the center of the first holding body 35.
Further, seat grooves 35a are symmetrically formed in the lower surface of the first holding body on opposite sides of the through hole 35b.
Further, an insert hole 55a is formed in the locking part 55 that is provided in the lower end of the supporting member 50.
Further, a locking pin 60 is provided. To combine the supporting member and the first holding body with each other, the locking pin 60 is inserted into the insert hole 55a after the supporting member 50 is inserted into the through hole 35b.
Thereafter, the locking pin 60 is seated in the seat grooves 35a.
When the lower end of the supporting member 50 is combined with the first holding body 35, the holding means FM performs the following function.
The holding means FM can more easily and efficiently combine the supporting member 50 and the first holding body 35 with each other.
Further, the assembled holding means can prevent the supporting member 50 and the first holding body 35 from being released from each other by vibrations or shocks that may be applied both to the supporting member and to the first holding body when a user wearing the shoes walks.
To realize the above-mentioned function of the holding means FM, the locking pin 60 of the holding means FM is seated in the seat grooves 35a of the first holding body 35 after the locking pin 60 has been inserted into the insert hole 55a of the supporting member 50 so that the locking pin 60 can hold and prevent rotation of the supporting member 50 irrespective of vibrations or shocks that are applied to the supporting member.
Fig. 7 illustrates a modification of the holding means FM.
In the modification, an internal thread 35f is formed on the inner circumferential surface of the through hole 35b of the first holding body 35, and an external thread 55b is formed around the outer circumferential surface of the locking part 55 of the supporting member 50 so that the supporting member 50 can be tightened to the holding body 35 by rotating the supporting member relative to the holding body.
In the above state, it is preferred that the upper surface of the head 51 of the supporting member 50 be recessed to form a straight recess, a cross recess or a combined recess so that the supporting member and the first holding body can be easily assembled and disassembled using a tool.
Hereinbelow, the structure for combining the supporting member 50 with the second holding body 37 using the stopping means SP will be described with reference to Figs. 2 through 7.
A stopper 37b is formed in the lower part of the corresponding guide part 37a of the second holding body 37.
That is, the stopper 37b is formed on the lower surface of the protruding spacer part 36 of the second holding body 37.
Further, a shank passing hole 37f is formed through the center of the protruding spacer part 36. Here, the diameter of the shank passing hole 37f is less than inner diameter of the corresponding guide part 37a but is greater than that of the shank 53.
The stopper 37b is formed in the shape of a step at an area around the shank passing hole 37f.
Accordingly, when the shank 53 of the supporting member 50 passes through the shank passing hole 37f, the shank 53 can move through the shank passing hole 37f when the elastic member 40 is compressed and reverts back to its original shape after yI ~
having been compressed.
Further, when the elastic member 40 fully extends and completely reverts back to its original shape, the head 51 that is connected to the upper end of the shank 53 of the supporting member 50 can be caught and held by the stopper 37b.
Therefore, it is possible to prevent removal or separation of the supporting member 50 from the second holding body 37.
Although the shock absorbing shoe with improved assembly and operational performance of the present invention has been disclosed based on specific shapes and directions in the above description, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
