Description

Health-care correcting insole and sandal

Technical Field

The utility model belongs to the field of correction health care equipment, and particularly relates to a health care correction insole and a sandal.

Background

The foot is the most heavy part of the human body, including numerous joints and ligaments, but because of sports injury in daily life, improper shoe wearing and the influence of certain congenital genetic factors, the foot ligaments are damaged or bones are dislocated and deformed due to long-term accumulation, abnormal gait or pathological gait is formed, and the health of people is seriously influenced.

After gait is abnormal due to long-term pathological changes of muscles, bones and ligaments of feet, pathological adaptive changes can also occur to muscle distribution and ligament coordination of legs, so that X-shaped legs, 0-shaped legs, knees and the like are excessively bent, the attractiveness of people is influenced, and the health of people is also seriously influenced.

Each part of the correcting insole has different thickness, namely, the force application mode during the motion of feet and legs is corrected through the thickness or hardness change of the insole, but when a user walks, the force application on the feet is unbalanced and the impact is large when the user walks easily or does motion due to the fact that the thickness of the correcting insole is different, and the phenomenon of foot spraining often occurs.

Therefore, the existing corrective insoles have the following problems:

1. the comfort is not good; the height difference is large, and the comfort of feet is not good;

2. easy sprain of feet: when the foot is touched to the ground during exercise, the stress on the sole is unbalanced at the moment, so that the foot is easily sprained to cause joint or ligament injury.

SUMMERY OF THE UTILITY MODEL

The upper end supporting layer of the spring is partially hinged and fixed with the lower end supporting layer of the spring so as to reduce the risk of damage to the buffer spring caused by horizontal sliding of the correcting insole.

The buffer springs comprise a plurality of springs with different elastic coefficients, and the springs with different elastic coefficients are arranged at different positions to change the motion stress mode of the foot and the leg, so that the correction of specific muscles, ligaments or joints of the foot or the leg is realized.

Through the use of springs with various elastic coefficients, the surface of the correction insole keeps a normal and smooth state when the correction insole is deformed without being stepped on, and when the sole of a foot is gradually contacted with the ground, the buffer springs in the correction insole are compressed and deformed by pressure until the correction state of the correction insole is reached. Therefore, the correction of the foot or the leg is a soft correction process with buffering effect due to gradual change of force by the aid of spring deformation, stress impact caused by sudden shape and position change is avoided, using comfort of the correction insole is improved, and sprain of the foot caused by overlarge correction force impact is greatly avoided.

The buffer spring comprises one or more variable stiffness springs, the spring with high elastic coefficient is required to be arranged at a local position where supporting force is strong, the spring with high elastic coefficient makes local touch harder and comfortable, and the variable stiffness spring has the advantages that the force is soft in the early stage of foot landing compression and the supporting force is sufficient in the later stage of compression.

When the thin area of the thickness offset insole and the buffer spring are positioned on the inner side of the foot, the correcting insole can achieve the effects of thinning the inner side of the thigh, correcting the eversion of the crus and correcting the O-shaped leg.

When the thin area of the thickness offset insole and the buffer spring are positioned on the outer side of the foot, the correcting insole can achieve the effects of thinning the outer side of the thigh, correcting the inversion of the shank and correcting the X-shaped leg.

The insole of the utility model is to be understood in a broad sense, and can be directly combined with the sole or directly used as the sole, except for the insole which is placed in the shoe.

The sandal comprises the health-care correcting insole, the health-care correcting insole and the sandal are of an integral structure or a split combined structure, and the sandal is provided with an upper or a shoelace for fixing feet.

In summary, the utility model has the following beneficial technical effects:
