Balance shoes with inbuilt spring

Abstract

The invention relates to a pair of balance shoes with an inbuilt spring, comprising the upper of a shoe, a PU outsole and an elastic outsole, wherein the upper of a shoe forms a main body of the shoe surface, the PU outsole performs the supporting action on the upper of the shoe, and the elastic outsole is arranged on the bottom of the shoe; the PU outsole and the elastic outsole are combined in the front part in the rotating mode, the rear part between the PU outsole and the elastic outsole is provided with a middle bin performing the buffering action; the middle bin and the rear part of the PU outsole connected with the middle bin are respectively provided pores, pores on two parts are communicated to form a spring slot, and a coil-shaped spring is inserted into the spring slot from top to bottom. The spring can be inserted into the spring slot to finish installation by that a TPU lower cover, a TPU upper cover and a spring fix the upper end of the spring, wherein the TPU lower cover is fixed on the PU outsole, the TPU upper cover is combined on the TPU lower cover in a dismountable mode, so that the spring can be simply and stably combined between the PU outsole and the elastic outsole, the spring can be taken out along with the TPU upper cover, and consumers can replace or maintain the spring by self.

Description

technical field [0001] The invention relates to a spring shoe, in particular to a spring built-in balance shoe. Background technique [0002] Shoes are worn on the feet in order to protect the feet that bear the most load in the human body, and spring shoes support or disperse the load of the human body in an elastic manner. Considering the law of people’s feet landing on the ground when walking, first the heel lands on the ground, then moves continuously from the center of the heel to the toe, and then the toe pushes the ground to leave the ground, thus forming a walking process of repeated landing and separation from the ground Therefore, the heel that first touches the ground when landing on the ground has to bear a large load. In order to protect the heel and prevent the impact force of the heel load from being transmitted to the joints and causing joint damage, people generally use spring shoes to cushion the heel. load distribution. [0003] Existing spring shoes are...

AI Technical Summary

Problems solved by technology

The above-mentioned spring shoes usually form a spring installation space between the midsole of the shoe and the outsole in contact with the ground, and the spring is respectively combined with the midsole and the outsole of the shoe by screws and other parts at both ends of the spring. It is also necessary to ensure that the spring will not be biased or disengaged under normal conditions, so it is generally necessary to arrange a device for positioning the two ends of the spring on the bottom surface of the midsole and the top surface of the outsole. The initial manufacturing can be carried out smoothly, but when the spring and other parts are damaged, the repair or replacement work is very difficult, and generally professional and technical personnel are required to operate

[0004] There are also some spring shoes. In order to facilitate the replacement or maintenance of the spring, the spring is exposed, so that the midsole of the shoe is separated from the outsole by a certain distance, and the spring is installed within this distance. This method is convenient for observing the spring, but when the spring etc. When a component is damaged, it can only be repaired or replaced by professional technicians, and ordinary consumers cannot operate it by themselves. Moreover, the appearance of this exposed spring is not acceptable to most ordinary consumers. In addition, the spring Other parts are easy to get dirty, but cause trouble for the wearer
