|20120209406||Foot Plate Device for An Artificial Foot - A foot plate device is connected to a prosthetic lower leg of an artificial foot, and includes a flexible foot plate. The foot plate has a front plate section, an inclined intermediate plate section extending rearwardly and upwardly from a rear end of the front plate section, and a rear plate section extending rearwardly from a rear end of the intermediate plate section and generally parallel to the front plate section. The front plate section has at least one open-ended slot formed vertically therethrough and extending across the front plate section along a longitudinal direction of the foot plate, so as to divide the front plate section into two force-receiving plate portions. The rear plate section is connected with the prosthetic lower leg.||08-16-2012|
|20120205206||Hydraulic Buffer Device - A hydraulic buffer device includes a first chamber, a second chamber, and a buffering space disposed under the first and second chambers, an air bladder disposed in the buffering space, an oil chamber disposed above the first and second chambers and divided by a piston into upper and lower chamber portions, and an annular passage disposed around the oil chamber. When the piston is moved downwardly within the oil chamber, the hydraulic oil flows from the lower chamber portion into the buffering space via the first chamber to contract the air bladder so that, upon expansion of the air bladder, air pressure in the air bladder pushes the hydraulic oil to flow from the buffering space into the upper chamber portion via the second chamber and the annular passage.||08-16-2012|
