Description

Muscle reinforcement member and shoes including the same

The present invention relates to a muscle strengthening member capable of strengthening muscle strength during walking and a shoe including the same.

In general, shoes are worn to protect the feet of the human body, and are manufactured and marketed in a wide variety of shapes and types. However, in general, shoes have an upper that covers and protects the instep and ankle, and an upper that protects the sole of the foot while protecting the ground. It is composed of a sole that improves the walking performance by increasing the friction of In the case of such conventional shoes, in order to absorb the shock transmitted from the ground to the soles of the feet during walking, an insole is laid on the inner bottom surface of the shoe, or the sole and heel part of the shoe are made of rubber and foamed sponge materials with excellent cushioning power, Alternatively, it is known that an elastic restoring member such as an air bag or a spring is built into the shoe sole. However, these conventional shoes only provide walking convenience and rather alleviate the involvement of the wearer's muscle strength during walking, so the reality is that they are not helpful at all in improving the wearer's muscle strength. Therefore, there is a demand for shoes that allow the wearer's muscles to actively intervene in the walking only after wearing and to develop the wearer's muscle strength.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings, however, since these are only examples, it can be seen that the present invention is not limited to these examples.

In describing the present invention, the detailed description of the parts that do not appear to be of great help in simply and clearly conveying the gist of the present invention will be omitted.

And, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary depending on the intention or custom of the user or operator, so the definition may be specified based on the content throughout this specification. can be seen as a problem.

The muscle strengthening member of the present invention and a shoe including the same, which will be described below, induce an exercise load on the muscles associated with most gait of the lower extremities as well as the feet and ankles of the wearer, thereby imparting an appropriate exercise effect through gait.

Conventional sports shoes and the like are manufactured by emphasizing only more comfortable walking, and the intervention of various types of walking-related muscle strength of the wearer is minimized, making it somewhat difficult to obtain the effect of exercise.

In the present invention, various gait-related muscles of the wearer are intervened during walking, so that the relevant muscles of the wearer can see the effect of movement simply by walking. Such effects and configurations will be described below with reference to FIGS. 1 to 7 .

1 is a view showing a shoe 1 including a muscle strengthening member 100 according to an embodiment of the present invention.

Referring to FIG. 1 , a shoe 1 including a muscle strength reinforcing member 100 includes an outer skin 10 surrounding the back of the foot, and a sole 20 coupled to the outer skin 10 . In addition, at least a portion of the muscle strength reinforcing member 100 may be disposed inside the sole 20 in a retracted state. The sole 20 may be formed through bonding between various materials such as plastic, fiber, silicone, rubber material, urethane foam, and the like. Accordingly, the sole 20 may have a flexible texture. As described above, the muscle strength reinforcing member 100 inserted into the inner sole 20 of this texture may be made of an elastic material to maintain a predetermined shape.

For example, the muscle strength reinforcing member 100 may be made of a metal material having an elastic deformation section. However, the material is not limited thereto, and reinforced plastics made of non-metallic materials having elasticity may be applied. Hereinafter, a description will be given of the shoe 1 in which the muscle strength reinforcing member 100 , which is a metallic material having elasticity, is inserted into the sole 20 .

The muscle strength reinforcing member 100 is basically formed of an elastic material and may have a basic shape extending in a parallel straight direction from the ground 3, and when an external force is applied, it is deformed into a shape other than the straight direction. It can be restored in a straight direction by the elastic restoring force. Here, the magnitude of the elastic force may be determined through the thickness, material, etc. of the muscle strength reinforcing member 100 . Specifically, the elastic force of the muscle strengthening member 100 may be determined by the width of the cross-sectional area of the lateral cross-section in the ball direction of the foot. Of course, the larger the area, the more difficult the deformation may be. Accordingly, the muscle strength reinforcing member 100 may be selectively determined in consideration of physical conditions such as the wearer's weight.

2 is a view showing that the muscle strengthening member 100 according to an embodiment of the present invention is positioned on the wearer's foot. Referring to FIG. 2 , the sole 2 of the wearer wearing the shoe 1 and the In (1), the built-in muscle strengthening member 100 is shown to indicate that each position corresponds to each other.

First, the muscle strength reinforcing member 100 may include a first elastic holding part 120 , a second elastic holding part 130 , a connecting part 110 , an elastically extending part 140 , and a discharging part 150 . The first elastic holding part 120 may be located in the front with respect to the metatarsophalangeal joint. That is, the section between the toe and the metatarsophalangeal joint or the lower part of the toe may be positioned to extend in the transverse direction. Here, the transverse direction may be the ball direction of the foot. And the second elastic holding part 130 may be disposed with the first elastic holding part 120 and the metatarsophalangeal joint therebetween. That is, it can be arranged in the section between the metatarsophalangeal joint and the heel.

The connecting part 110 may connect the first elastic holding part 120 and the second elastic holding part 130 disposed with the metatarsophalangeal joint therebetween. That is, one end of the connection unit 110 may be connected to the first elastic holding unit 120 , and the other end may be connected to the second elastic holding unit 130 . In this way, a plurality of connection parts 110 connecting the first elastic holding part 120 and the second elastic holding part 130 may be provided. In this example shown in FIG. 2 , the connection part 110 is a type including a first connection part 111 , a second connection part 112 , and a third connection part 113 , and the connection part 110 may further include such a configuration. It may or may not contain only one. That is, at least one connection part 110 is included, and when only one is included, it may be preferably provided in a form in which the central portions of the first elastic holding part 120 and the second elastic holding part 130 are connected to each other. This will be specifically described later with reference to FIG. 5 .

On the other hand, the connection part 110 may be located at a position corresponding to the metatarsophalangeal joint. When the wearer walks, the front may be in contact with the ground 3 based on the metatarsophalangeal joint, and the rear may be in a state spaced apart from the ground. That is, bending of the muscle strength reinforcing member 100 may occur in the metatarsophalangeal joint. The occurrence of such bending causes an elastic restoring force to be generated from the connection part 110 .

Accordingly, the wearer generates resistance to a step in the direction he intends to advance while walking, so that relatively more muscle intervention is required for walking. Not only the foot muscles, but also the lower body muscles including the ankle, calf, soleus muscle, shin, quadriceps femoris, gluteus maximus, gluteus maximus and gluteus medius are more naturally and actively involved in gait. Furthermore, some muscles of the upper body, such as the back, may be involved and tensed as an auxiliary. Accordingly, various muscles can be activated by increasing the use rate of the muscles through walking.

In addition, the discharge part 150 may be provided in the elastic extension part 140 extending from the second elastic holding part 130 to the heel. Here, the elastic extension 140 may extend from the second elastic holding part 130 to a point exceeding the long core of the sole 2 . This may be a factor in determining a position where the discharge unit 150 may be selectively formed. Specifically, the section on the elastic extension section 140 overlapping among the elastic extension section 140 in the longitudinal direction, which is the length of the foot, and the long core section forming section in the longitudinal direction, is the arrangement section in which the discharge section 150 is formed. can That is, it is located on the elastic extension 140, it means that it is preferably located in the section where the long core is formed.

This is due to the characteristics of the discharge unit 150, since it is exposed to the outside through the bottom surface of the sole 20, when the traction force is distributed to the discharge unit 150, which is a metal material, the contact area between the discharge unit 150 and the ground 3 is Since the traction force is relatively lower than the traction force between the sole 20 and the ground 3, it means that it is advantageous to be positioned on the long core side with a low dependence on the traction force. A significant part of the body pressure generated through the foot occurs in the metatarsophalangeal and heel, and the long core is formed as the lowest body pressure region. By making contact, gait stability can be maintained.

3 is a side view of a shoe 1 including a muscle strength reinforcing member 100 according to an embodiment of the present invention. And, Figure 4 shows a state in which the muscle strength strengthening member 100 according to an embodiment of the present invention is disposed with respect to the ground (3), Figure 4 (a) is the front surface of the sole 20 is the ground (3) It is a view showing a state in contact with, Figure 4 (b) is a view showing a state in which only the front area of the sole 20 from the metatarsophalangeal joint is in contact with the ground (3).

3 and 4 , the discharge unit 150 in contact with the ground 3 may be provided on the elastic extension unit 140 . In addition, as the wearer of the shoe 1 is repeatedly contacted and separated while walking, the contact portion 3 ′ may be repeatedly generated. This separation and contact is due to the joint movement of the metatarsophalangeal joint, and as the joint movement causes the connection part 110 at the position corresponding to the metatarsophalangeal joint to bend, the elastic extension part 140 rotates within a predetermined range. It can be rotated by an angle (R). That is, the wearer feels resistance to walking by the elastic restoring force generated in the connection part 110 .

On the other hand, if the step during walking is divided into steps, it can be divided into heel step, weight scale, intermediate step, toe step, toe step, initial mover, intermediate mover, and end mover. The state shown in Fig. 4(a) may be a weight scale, and the state shown in Fig. 4(b) may be a toe stepper. In one embodiment of the present invention, it is possible to induce more active muscle intervention by directly generating an exercise load on the foot including the toe during the intermediate stepping phase, the toe stepping phase, and the toe-off process.

5 is a view showing various examples of the connection part 110 applicable to the muscle strength strengthening member 100 of the present invention through FIGS. 5 (a) to 5 (d),

Referring to FIG. 5( a ), as an embodiment in which the connection part 110a is one, the first elastic holding part 120 and the second elastic holding part 130 are connected by a single connection part 110a. This may have the lowest elastic restoring force under the premise that the conditions such as the material and thickness of the muscle strengthening member 100 are the same as in the examples shown in FIG. 5 . The connection part 110a may connect the centers of the first elastic holding part 120 and the second elastic holding part 130, respectively. Therefore, it can be said that it is located on the middle finger side of the toes.

This is to effectively generate an elastic restoring force in a direction in which the connection part 110a is bent. That is, regardless of the number of connection parts 110, 110a, 110b, 110c, the first elastic holding part 120 and the second elastic holding part 130 are connected by the connecting parts 110, 110a, 110b, 110c. It is preferable that both sides of the structure be symmetrical with respect to the connecting portions 110, 110a, 110b, and 110c.

5( b ) is an example described above, and includes three connection parts 110 , and the connection parts 110 are formed symmetrically to each other. In addition, an embodiment including a plurality of connecting parts 110 may be provided in a form in which both ends of the first elastic holding part 120 and the second elastic holding part 130 are connected to each other. In this structure, when the connecting portion 110 is asymmetrical when the connecting portion 110 is bent, torsion also occurs, so that the torsion of the sole 20 may occur due to repeated use of the shoe 1, so the connecting portion 110 ) is preferably symmetrical when connected to the first elastic holding part 120 and the second elastic holding part 130, and in the case of a plurality of connecting parts 110, the first elastic holding part 120 and It is preferable to have a method for connecting both ends of the second elastic holding part 130 to each other.

The example shown in FIG. 5( c ) can also be said to be an example that satisfies the arrangement requirements of the above-described preferred connection parts 110 , 110a , 110b , 110c . Furthermore, FIG. 5( d ) is an example in which five connection parts 110c are arranged, and may be included in the same number of each toe (a general case of five toes as an example). There may be some differences depending on the position of the toes, but among the disclosed examples, it may be an example that can transmit the elastic restoring force most evenly.

On the other hand, the first elastic holding part 120 and the second elastic holding part 130 of the above examples may also function as a configuration for preventing bending (banding). For example, unlike the connection part 110 that generates an elastic restoring force with respect to the aforementioned bending in the longitudinal direction, it provides resistance to the wearer from bending in the transverse direction. That is, an elastic force for restoring the present state is generated against bending in the lateral direction, and the first elastic holding part 120 , the second elastic holding part 130 and the connecting part 110 connected to each other are connected through this. An elastic restoring force is generated against bending in the longitudinal and transverse directions, so that it can be restored to its original state.

6 is a view showing various examples of the discharge unit 150 of the present invention through FIGS. 6 (a) to 6 (c).

Referring to FIG. 6 , each example according to the contact type of the discharge unit 150 is shown. FIG. 6( a ) may be in line contact with the ground 3 . This example is of the same type as the above-described example, and since the discharge part 150 convexly formed toward the ground 3 or most of it is drawn into the sole 20 and only the end of the ground 3 side is exposed, it is in the form of a line. may be exposed. Accordingly, static electricity can be discharged through line contact with the ground (3). This can be prevented by grounding the static electricity generated by friction between the wearer and the shoe 1 from staying in the body afterward, since the discharge is performed under the condition that the discharge is possible through contact with the ground 3 at every step during walking.

In the case of FIG. 6(b) , only a part of the discharge part 150a protrudes and may be exposed to the outside to make point contact (contact with a relatively narrow area). In this case, since it may be structurally vulnerable to load, it may be preferably formed at a point where body pressure is measured low even in the long core. Although it is not provided adjacent to the extension path of the elastic extension part 140, the exposed position can be relatively freely provided by the extension of the discharge part 150a. In the case of FIG. 6(c) , it is an example of the discharge unit 150c that performs discharge through surface contact, and may be exposed to the ground 3 side in a surface shape.

7 is a view showing the elastic pressing unit 160 according to an embodiment of the present invention, FIG. 7 (a) is a view showing the elastic pressing unit 160 formed in the muscle strength strengthening portion, Figure 7 (b) is a sole It is a view showing the elastic pressing unit 160 protruding upward through the 20.

7 (a) and 7 (b), the muscle strength strengthening member 100 further includes an elastic pressure portion 160 protruding from the first elastic holding portion 120 toward the wearer's toes.

The elastic pressing part 160 may be provided separately by being attached to the first elastic holding part 120 , or by partially bending the first elastic holding part 120 to protrude upward to be provided as an elastic pressing part 160 . may be

The elastic pressing unit 160 is one means for more effectively discharging, and is in contact with the wearer's toes, and the muscle strength reinforcing member 100 as a conductor may discharge static electricity through the discharging unit 150 . This may be exposed to the inside of the shoe 1 by penetrating a portion of the sole 20 upward from the first elastic holding part 120 drawn into the sole 20 . Therefore, it can come into contact with the wearer's toes. Therefore, it can be a structure that induces to discharge static electricity.

Although representative embodiments of the present invention have been described in detail above, various modifications may be made to the above-described embodiments of the present invention without departing from the scope of the present invention. Therefore, it is considered that the scope of the present invention is not limited to the described embodiments and should not be determined, and it is considered as a matter that should be determined equally and justly by the various matters related to the claims as well as the claims to be described later. .
