Technical Field

The invention relates to a sole muscle strengthening pad and an insole comprising the same.

Background

In general, foot stability affects a person's upright posture and postural stability. When the foot is unstable, musculoskeletal system diseases such as plantar fasciitis, achilles tendonitis, ankle sprain, limited functional activity of the big toe, anterior cruciate ligament injury, back pain, etc. may be induced, and thus plantar muscle strengthening exercise may be required in order to prevent such diseases.

The feet and legs of a person are functionally related. That is, the musculoskeletal composites including the pelvis, knee, ankle, and foot are interconnected to transfer the stability of the foot to the pelvis.

Therefore, if a user suddenly walks or exercises after sitting for a long time, the calf muscle or the sole muscle, which lose elasticity, may be inflamed and painful due to being overloaded. The longer the sitting time is, especially the larger muscles of the lower limbs, such as the buttocks and popliteal muscles, become weaker.

When walking or exercising in this state, the calf muscles or the foot muscles are used, causing the muscles to become stiff and excessively contracted, thereby causing pain.

In addition, the foot's internal muscles provide a basic stabilizing function for various factors of the foot and ankle joint, and at the same time, provide a local stabilizing function inside the foot, a dynamic supporting and controlling function, i.e., optimizing the structural changes of the foot to adapt to various grounds and environments to ensure stable ground contact, and in the motion of the foot, it is an important part of the function of regulating the amount and timing of muscle activation to cope with the conditions and environments.

In order to strengthen the plantar muscles in the case of stabilizing the toes, a plantar muscle strengthening exercise device capable of preventing musculoskeletal system diseases has been proposed in "plantar muscle strengthening exercise machine (registered number: 10-1951007)", which is composed of a front frame part, a rear frame part, a moving part and a support part, but the plantar muscle strengthening exercise machine is of a sandal type structure that can be worn on the foot, and therefore, the plantar muscle strengthening exercise device cannot absorb and buffer the impact force of the sole during walking, and cannot be inserted into an insole capable of improving wearing feeling when reducing the feeling of fatigue of the wearer's foot, and thus, the plantar muscle strengthening exercise device has been difficult to be commercialized in practice.

Therefore, there is an urgent need to develop a new technique for enhancing the foot musculature movement through the insole, which is not only helpful for treating flatfoot, plantar fasciitis and hallux valgus, but also for correcting gait.

Detailed Description

The present invention will be described in detail below.

Before explaining the present invention, it is most desirable that the moving direction of the center of gravity of the sole during walking is the direction of the arrow A → B → C shown in FIG. 1, and that the weight is dispersed toward the big toe through the outer side of the sole and the ball of the foot from the heel.

However, if the stability of the foot from lateral to medial touchdown is not controlled, the foot becomes unstable, resulting in pelvic dislocation and abnormal structural deformation. Eventually, lack of stability of the foot can cause pain and damage to the entire leg.

The diseases caused by this include plantar fasciitis (plantar fasciitis), Functional hallux valgus (Functional hallux extremity-rididus), Achilles tendonitis (Achilles tendonitis), chronic ankle instability-ankle sprain (chronic ankle instability-ankle sprain), anterior cruciate ligament injury (ACL injury), and low back pain (low back pain).

In addition, referring to fig. 2, if active movement of the intrinsic muscles of the foot is not performed normally, diseases that may be caused when the intrinsic muscles of the foot are not activated may cause achilles tendonitis, posterior tibialis tendonitis, plantar fasciitis, blisters, toe hematoma, and the like.

To prevent this, in the present invention, not only helping to treat flatfoot, plantar fasciitis, hallux valgus, etc. by guiding the moving path of the center of gravity to be normal while strengthening the intrinsic muscle movement of the foot during walking, but also showing an insole 10 for treating flatfoot, a plantar muscle strengthening pad 100 is inserted between a bottom layer member 11 and a top layer member 12 of the insole 10.

In relation, fig. 3 is an exemplary view of a plantar muscle strengthening pad 100 according to the present invention; fig. 4 is a perspective view of insole 10 with plantar muscle strengthening pad 100 inserted therein according to the present invention; FIG. 5 is an exploded view showing FIG. 4; FIG. 6 is a top view showing the bottom of FIG. 4; fig. 7 is a side view showing the side of fig. 4.

Referring to fig. 3 to 7, the sole muscle reinforcing pad 100 of the present invention includes an arch support 110, a forefoot support 120, and a connecting portion 130, and when a load is applied to the rear foot during walking, the weight of the foot is transferred to the forefoot through the outer side of the sole, and when the metatarsals contact the forefoot support 120 and are stimulated, the direction between the big toe and the second toe is vector-changed to generate a driving force, thereby having a characteristic of correcting gait.

At this time, a soft cushion material 100b may be inserted into the protective member 100a constituting the outer shape of the plantar muscle reinforcing pad 100, and the cushion material 100b is a urethane foam in this example. By inserting the cushioning material 100b in the protective member 100a, cushioning effect and elasticity can be imparted to the footwear insole 10 when walking on the ground. In some cases, the inside of the protective member 100a of the plantar muscle strengthening pad 100 may be filled with nitrogen instead of the polyurethane foam.

In the present invention, the arch support 110 is a structure supporting the arch. Arch support 110 is provided inside insole 10 to ensure a position corresponding to the arch of the wearer's foot. The first arch line 111 formed to extend along the medial line of the sole and the ends of the first arch line 111 are bent outward as they go forward, thereby activating the intrinsic muscles of the foot when walking and contributing to the formation of the arch.

In the present invention, the forefoot support portion 120 is positioned in front of the arch support portion 110 and supports the forefoot. The forefoot support 120 and the arch support 110 may be connected by a connection 130. The forefoot support portion 120 may be composed of a first forefoot support line 121 formed to extend from an end of a first connection line 131 of the connection portion 130, a second forefoot support line 122 bent at a distal end of the first forefoot support line 121, a third forefoot support line 123 bent again at a distal end of the second forefoot support line 122, and a fourth forefoot support line 124 bent inward at a distal end of the third forefoot support line 123 and connected to a second connection line 132 of the connection portion 130.

In the present invention, the connecting portion 130 serves to connect the arch support 110 and the forefoot support 120. In detail, the arch support 110 is provided at one end of the link 130, and the forefoot support 120 is provided at the other end of the link 130. In more detail, the connection portion 130 is surrounded by a first connection line 131 extended from a first arch line 111 of the arch support 110 and a second connection line 132 formed in an extended manner on a second arch line 112 of the arch support 110, so that an elastic force can be transmitted between the arch support 110 and the forefoot support 120.

Referring to fig. 3, when the center of gravity shifts from the sole and reaches the boundary point P corresponding to the corner between the third forefoot support line 123 and the fourth forefoot support line 124 while walking, the big toe is lifted to obtain propulsive force due to the change of the vector in the big toe direction or the direction between the big toe and the second toe.

If weight is transferred from the heel to the lateral side of the foot while walking, the ankle may be severely twisted or sprained if there is no change in the turning vector in the hallux direction, resulting in spraining or falling of the ankle joint due to damage to ligaments supporting the ankle joint.

Therefore, in the internal muscular movement of the foot, it is more important to exercise the movement or strength control of the muscles than to strengthen the muscular strength of the internal muscles of the foot, and thus the internal foot muscle reinforcement pad 100 according to the present invention can function as a stimulation point.

Specifically, referring to fig. 5 to 7, an arch support 13 having an arch structure is upwardly protruded from a position of the bottom layer member 11 of the footwear insole 10 corresponding to the arch of the wearer's foot.

That is, the arch support 13 having a relatively cushion feeling compared with the bottom surface of the base member 11 is formed by air or the like at a position corresponding to the arch inside the base member 11, and contributes to forming the arch inside the foot while supporting the inside of the foot, and can prevent the formation of a flat foot.

The ankle sprain is caused by the inward expansion of the sole member 11 constituting the insole 10, and the body weight control part 14 formed by the ergonomic design so that the height of the other side of the arch support part 13 is raised upward prevents the ankle from being strained and allows the body weight to move in the directions of the big toe and the second toe before the body weight moves outward after the heel receives an impact during walking.

In this way, the sole of the foot can be stably supported only by the structure of insole 10, and a synergistic effect with the action of plantar muscle reinforcing pad 100 can be produced.

Referring to fig. 7, the height of the body center of gravity control part 14 is relatively lower than the height of the arch support 13 with respect to the upper surface of the base member 11, and if the height of the body center of gravity control part 14 is relatively higher than the height of the arch support 13, the weight of the sole of the foot may be inclined inward during walking, which is not preferable.

For reference, the top layer member 12 combined with the bottom layer member 11 may be formed of a soft fabric material, and thus may be bent and combined with the bottom layer member 11 having a just arch shape.

As described above, the present invention relates to a sole muscle reinforcing pad 100 and an insole 10 including the same, wherein the sole muscle reinforcing pad 100 includes an arch support 110 supporting an arch of the foot, a forefoot support 120 formed at a front end of the arch support 110 and supporting a forefoot, and a connecting portion 130 connecting the arch support 110 and the forefoot support 120.

Since the plantar muscle strengthening pad 100 is inserted into the insole 10, the big toe is lifted up to the outside between the big toe and the second toe when walking. As described above, the sole muscle reinforcing pad 100 is inserted between the bottom layer member 11 and the top layer member 12 of the insole 10 to actively move the intrinsic muscles of the foot, thereby facilitating the formation of the shape of the inner arch of the foot, and having an advantage of correcting the deformation such as hallux valgus only by walking.

In addition, since the pelvis, the knee, the ankle and the foot are organically connected, and the stability of the foot can be transmitted to the pelvis, the plantar muscle strengthening pad 100 according to the present invention has an important meaning that the sole of the foot is stably contacted with the ground to the maximum extent even in various ground conditions such as a gravel ground, a rope, etc., and the intrinsic muscle activity of the foot is promoted, and the structure of the foot is changed by appropriately forming the arch, thereby achieving dynamic stability.
