DAMPING HEEL WITH PNEUMATIC CHAMBER OF DOUBLE-SIDED ACTION Russian patent published in 2011 - IPC A43B21/00 

Abstract RU 2424751 C1

FIELD: personal use articles.

SUBSTANCE: damping heel has in its middle part a pneumatic chamber of double-sided action, filled with gas under the rated pressure depending on a person's weight and ambient temperature. Damping is carried out by means of pneumatic chamber compression on top from the pressure and vertical displacement of the heel part of a foot, transferred via a chain of movable parts, and also as a result of compression at the bottom, from the force reaction of the rigid support base, which is transferred by a set of movable parts. A valve inbuilt into the pneumatic chamber makes it possible to vary gas pressure, a threaded bush controls the value of the pneumatic chamber compression. A safety collar is used, which prevents ingress of foreign objects into movable joints, and is able to compress by half of the pneumatic chamber compression due to usage of low-module material. Comfort of shoe wear with the proposed damping device is provided due to the fact that the full run of damping is divided equally into the run of the heel portion of the foot and the tip displacement.

EFFECT: invention provides for comfort of shoe wear.
