Abstract: A shoe sole includes a chamber which is inflated by a pumping device via a connection tube. The connection tube includes a first valve to prevent air from flowing back into the pumping device and an inlet tube extends from the pumping device to introduce air from outside into the pumping device. A plurality of outlets are defined in a distal end of the connection tube and located corresponding to toes of the wearer. The connection tube has a neck portion which defines a narrowed path in the connection tube so that air is stopped at the neck portion to inflate the chamber, when the pressure of the air reaches to a pre-decided value, air passes through the neck portions and blows out from the outlets to cool the toes of the wearers.

Abstract: An airflow adjusting device is used in an air cushion shoe and includes an air cushion body having a buffer portion, an air inlet connected to the buffer portion and an air outlet connected to the buffer portion. When the buffer portion is impacted, the buffer portion will be compressed and thus induce an elastic force to have a buffer effect. When the buffer portion is compressed, air in the buffer portion will be drained out from the air outlet. When the compressing force disappears, the buffer portion will restore and air is sucked from the air inlet. An adjusting device including an adjusting seat and an adjusting button screwed on the adjusting seat; and a stopper being formed on the adjusting button for changing air flow rate of the air flowing out of the air outlet so as to change the elasticity of the buffer portion.

Abstract: A cushion cell for shoes includes a casing with an hour-glass-shaped compressible member received therein which is composed of a spiral wire extending in a vertical direction. The compressible member includes an upper portion and a lower portion, the spiral wire of the upper portion can be inserted in a corresponding spiral gap of the lower portion when the cushion cell is compressed. The distance that the compressible member is compressed is much longer than the chambers in a conventional outsole.

Abstract: A belt pressure reduction device comprises a combining portion being formed by folding two sides of a plane structure so that one side covers upon another side to form an adhering section so as to form a hollow receiving space within the combining portion for receiving an air cushion and a belt; one end of the air cushion being an airbag and another end thereof being an air inflation unit. The inflation unit serves to inflate air into the air cushion so as to cause the airbag to be elastic. The air cushion is not separated from the combining portion. The inflation unit of the air cushion exposes out of the combining portion. The combining portion is formed with at least one air hole. Two ends of the combining portion are foldable and unfoldable repeatedly.

Abstract: A cushion device for shoes includes a first bladder and a second bladder with a hose connected in communication therebetween. A compressible unit is received in the second bladder and has an outgoing hose extending therefrom. The outgoing hose is connected to an inlet of the first bladder. An inlet hose has an end located outside of the second bladder and the other end of the inlet hose is connected to the compressible unit. The wearer compresses the compressible unit to inflate the first and second bladders. When the load is disappeared from the compressible unit, air is sucked from the inlet hose to assist the compressible unit to return to the original status.

Abstract: A mold assembly for manufacturing an outsole includes a female mold, a first male mold pivotally connected to a side of the male mold and a second male mold pivotally connected to an end of the male mold. A peripheral wall defining the cavity has a separating flange extending inwardly therefrom. Each of the first male mold and the second male mole has at least one protrusion extending therefrom through which at least one passage is defined. The protrusion of the first male mold is inserted into the cavity and an outer surface of the protrusion abuts the separating flange. The first protrusion and the second protrusion are inserted into the cavity in sequence and material is injected into the cavity via the passages.

Abstract: The invention offers the three-color-side-wall rubber soles in easily changeable mode. It only referred to the integrated multicolor rubber soles which can be manufactured by a mould set with the changeability of color ring in various series. The invention may be directly applied to the streamline of soles to form shoe modes. The invention may be simply designed. In the meantime, it exprsses the unique characteristic properties.
