Stress-reducing insole
View Patent ↗A stress-reducing insole includes a cushion unit, a frame and a superficial layer. The cushion unit includes air bags connected to one another. Each of the air bags includes a valve via which air is pumped into or released from the corresponding one of the air bags. The frame extends around the cushion unit and includes bores for receiving the valves. The superficial layer covers one of two opposite faces of the cushion unit.
1. A stress-reducing insole comprising:
a cushion unit ( 10 ) having an outer perimeter, the cushion unit comprising air bags ( 12 ), wherein each of the air bags ( 12 ) comprises a valve ( 14 ) via which air is pumped into or released from the corresponding one of the air bags ( 12 );
a frame extending around the outer perimeter of the cushion unit ( 10 ) such that the cushion unit substantially fills an area encompassed by the frame and comprising two semi-frames ( 20 , 30 ), wherein each of the semi-frames ( 20 , 30 ) comprises bores ( 24 , 35 ) for receiving the valves ( 14 ); and
a superficial layer ( 50 ) coated on the frame.
2. A stress-reducing insole comprising:
a cushion unit ( 10 ) comprising independent air bags ( 12 ) and connectors ( 13 ) for connecting the air bags ( 12 ) to one another, wherein each of the air bags ( 12 ) comprises a valve ( 14 ) via which air is pumped into or released from the corresponding one of the air bags ( 12 ); and
two semi-frames ( 20 , 30 ) each of which comprises:
an internal face ( 22 , 32 ) shaped in compliance with a semiperiphery of the cushion unit ( 10 ); bores ( 24 , 35 ) for receiving the valves ( 14 ); and
two connective portions ( 23 , 34 ) formed at two ends, wherein the connective portions ( 23 ) of one of the semi-frames ( 20 ) are connected to the connective portions ( 34 ) of the remaining one of the semi-frames ( 30 ) so that the semi-frames ( 20 , 30 ) are joined to provide a frame around the cushion unit ( 10 ).
3. The stress-reducing insole according to claim 2 , further comprising a superficial layer ( 50 ) for covering one of two opposite faces of the frame.
4. The stress-reducing insole according to claim 2 , wherein the connective portions ( 23 ) of one of the semi-frames ( 20 ) are overlapped with the connective portions ( 34 ) of the remaining one of the semi-frames ( 30 ).
5. A stress-reducing insole comprising:
a cushion unit ( 10 ) having an outer perimeter, the cushion unit comprising independent air bags ( 12 ) connected to one another, wherein each of the air bags ( 12 ) comprises a valve ( 14 ) via which air is pumped into or released from the corresponding one of the air bags ( 12 );
a frame ( 70 ) extending around the outer perimeter of the cushion unit ( 10 ) such that the cushion unit substantially fills an area encompassed by the frame and comprising bores ( 71 ) for receiving the valves ( 14 ); and
a superficial layer ( 50 ) for covering one of two opposite faces of the cushion unit ( 10 ).
