Title:
SHOE SOLE AND INSOLE ACCOMPANIED BY CIRCULATION OF INJECTED FLUID
Document Type and Number:
Japanese Patent JPH01284205
Kind Code:
A
Abstract:
PURPOSE: To provide a sole and/or an insole accompanied with a fluid circulation therein of making possible to increase the sheet surface in contact with the sole of a foot, and to weld for perfectly preventing the leakage of a solution by composing of that the upper surface of a shoulder portion is connected to the upper surface of the body-plate of dividing the both of upper and lower chambers through a inclined surface, and the shoulder portion is formed by a convex shape. CONSTITUTION: The communication ports 7, 8 through which the upper and lower chambers between a body-plate 1 composing of a sole body and a shoulder portion 2 communicate with each other are formed. Reinforcing bars 9, 10 are fitted in the communicating ports 7, 8. The reinforcing bars 9, 10 are made so that the shoulder portion 2 located on the circumference of the communication ports 7, 8 is not deformed. The above deformation is caused by the pressure of a fluid which is filled in the inside space of the sole to massage the sole of the foot. A blade 11 has a central portion 13 which gives a righting moment when the central portion 13 is compressed, and the both side ends of the blade 11 is connected to the shoulder portion 1 and an inclined surface 5 through a thin web 14. A thin sheets 17, 18 are arranged on the blades 11, 15, and welded to the circumferential edge of the both of upper and lower surfaces 6, 6 of the shoulder portion 2. The surfaces 6, 6 are formed to a convex shape, and a pressure generated by compression of the shoulder portion 2 becomes larger than the edge of a belt zone at the central portion of the welded belt zone, thus a flexible and good sealing is obtained.
