PUSHING STRUCTURE FOR LEG WARMING DURING WALKING Russian patent published in 2009 - IPC A43B7/02 

FIELD: individual supplies.

SUBSTANCE: invention relates to pushing structures used for active leg heating and protecting from super-cooling during walking. The structure is represented as a footwear with sole, energy generator and pushing support with drive to energy generator. The sole has internal sealed cavity filled with an operating agent. There are also throttling heaters in the sole cavity. The latter is divided by the horizontal partition fixed to the sidewalls. Together with rear and front walls, the partition forms hydrodynamic windows. Enclosed generator is in the inner cavity of the sole. Energy generator is implemented with a movable piston having open-end channel and check valve. There is a piston packing ring on the side surface. The pushing support is installed under the sole and enclosure and protected from dust and dirt with elastic case. The pushing support is fixed at an angle to low sole base. Drive for energy generator is represented with a sliding pin with one end being connected to the movable piston and the other led out from inner cavity through the hydraulic seal and connected with the pushing support. During walking or running, an individual presses the pushing support by his weight and as a result, the operating agent starts moving through throttling heaters to inner cavities of the sole. Heat energy is generated, which is transmitted to the foot.

EFFECT: technical result provides for using device disclosed by this invention and improves its effectiveness and operational reliability for efficient warming of legs and protecting them from super-cooling during walking.
