Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sock insole for deforming the knee joint or for improving the impact absorption function of the reaction force from the ground by the elderly people with varus knee, etc., and relieving fatigue and injury of the foot below the knee joint. is there.

[0002]

[Prior art]

 The number of people who have difficulty in running is increasing due to osteoarthritis, especially osteoarthritis due to the elderly and bone fractures, and when ankle is attached, the knee deforms into a varus knee (O leg). .

As shown in FIG. 3, an elderly person or the like may swell around the knee joint between the femur 40 and the tibia 41 due to deformation of the knee joint, or may press the inner side 43 of the knee to cause pain. It may project outwards and the knees may become stiff and aching at the beginning of walking. It is considered that this is due to the X-ray image in which the spine is formed on the medial side 43 of the knee, the bone is hardened, the joint gap is narrowed, the femoral axis Y and the tibial axis Z are inclined, and the bow is outward. Reference numeral 42 is a fibula.

In addition, varus knee often occurs in the process of growing a child. Treatments for knee deformity include weight loss, internal use of anti-inflammatory analgesics, local warming, knee protection with supporters, etc. to strengthen the quadriceps. It was improved by repeated bending and extension of the knees, but there was no convenient way to treat while walking. For varus knees, there are attempts to correct them by putting orthosis or equipment on the body, but little effect can be expected, and if a very tight orthosis is used, it is impossible to exercise freely. There was a risk of adversely affecting the development of motor function.

[0005]

[Problems to be solved by the device]

 The present invention, by inserting a specially shaped insole into the shoe, trains the legs while walking, and the knee joint is deformed or the knee joint is deformed against the elderly such as varus knee and children. The purpose is to relieve fatigue and damage to the feet below the joints.

[0006]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an insole that is inserted inside the shoe, in which the part corresponding to the front and outer toes of the foot and the heel part are higher than other foot parts. It is what constitutes.

[0007]

[Work]

 Since the present invention is configured as described above, the gap between the joints inside the knee is expanded, the bone is displaced inward of the vertical axis, the compression on the inside of the knee is eliminated, the pain is improved, and the varus knee is also improved. Is also corrected. Wearing the insole also alleviates fatigue and damage to the legs below the knee joint and strengthens the muscles around the joint.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the foot of the human body includes the calcaneus 1, the talus 2, the scaphoid 3, the first wedge 4, the second wedge 5, the third wedge 6, the cubic bone 7, the first metatarsal. Bone 8, second metatarsal bone 9, third metatarsal bone 10, fourth metatarsal bone 11, fifth metatarsal bone 12, first proximal phalange 13, second proximal phalange 14, third proximal phalange 15, fourth phalanx 16, fifth phalanx 17, second medial phalanx 18, third medial phalanx 19, fourth medial phalanx 20, fifth medial phalanx 21, first distal phalanx 22, The second distal phalanx 23, the third distal phalanx 24, the fourth distal phalanx 25, and the fifth distal phalanx 26 are included.

On the other hand, the insole 30 is composed of an upper layer 31, a middle layer 32, and a lower layer 33. Each of these layers is adhesively laminated with an adhesive or the like.

The upper layer 31 is made of, for example, synthetic fiber woven fabric, knitted fabric, non-woven fabric, natural leather or artificial leather. The middle layer 32 is made of a flexible material such as a synthetic resin foam sheet or synthetic rubber. The lower layer 33 is made of synthetic fiber woven fabric, knitted fabric, or the like, and has elasticity against bending.

As the material for the insole, polyester fiber, nylon fiber, glass fiber, carbon fiber, metal fiber, etc. woven in satin weave, twill weave, plain weave in the upper layer, polyurethane foam in the middle layer, the lower layer A fiber reinforced thermoplastic resin or vinyl chloride sheet reinforced with a non-woven fabric composed of thermoplastic filaments can be used.

Alternatively, the middle layer may be formed by impregnating a foaming material such as latex foam, soft rubber foam, EVA foam, or the like with a thermoplastic adhesive, and compressing and solidifying the upper layer and the lower layer to integrate them. As shown in FIG. 1 (A), the midsole 32 of the insole includes the calcaneus 1, a part of the talus 2, a part of the third metatarsal bone 10, the fourth metatarsal bone 11, and the fifth metatarsal bone 12. , Third proximal phalanx 15, fourth proximal phalanx 16, fifth proximal phalanx 17, third medial phalanx 20, fourth central phalange 21, fifth central phalange 22, third distal phalanx 24, third It is provided in the shaded part including the 4th phalanx 25 and the 5th phalanx, and this part is laminated in three layers as shown in FIG. 1 (B) and FIG. 1 (C), and the other part is the upper layer 31. The lower layer 33 is composed of two layers. As shown in FIG. 2, the thickness of the middle layer is about 5 to 10 mm, and the angle α with respect to the horizontal plane is preferably 2 to 3 degrees. The insole supports the anterior lateral and heel parts of the foot higher than the rest of the sole, so that the weight is placed on the inside of the foot.

As a result, when the insole is laid inside the shoe, the outside of the foot is pushed up, and the gap between the joints inside the knee is widened as shown in FIG. The pressure on the affected part is reduced, and the vertical axis X of the bone becomes linear. The thickness of the middle layer is appropriately selected according to the symptoms of the user. The present invention is not limited to the above embodiments, and various combinations of layers of the embodiments can be modified.

[0014]

[Effect of device]

 Since the present invention is configured and operates as described above, the weight of the insole moves inward of the foot so that the vertical axis of the foot is aligned and the femoral axis and the tibial axis are aligned during walking. It relieves fatigue of the legs due to weight and reaction force from the ground, removes and relieves pressure on the knees, and eliminates stiffness and pain. In addition, the varus knee is corrected and the deterioration of the deformation due to the load on the inside of the knee can be prevented.
