PLATFORM FOR MEASURING THE POSITION OF THE CENTER OF GRAVITY IN A STANDING SUBJECT

摘要

P Device for measuring the position and excursions of the center of gravity of a subject standing on said device. According to the invention, the body of the device is a platform made up of two plates made of a material of high stiffness. for example aluminum "AU 4 G", sandwiching in a particular arrangement at least three sensors (11) and incorporating all of the processing electronics. The force sensors used in this invention are miniaturized, of the "button" type. The upper plate (5) rests on the pins of the sensors by means of hard steel bowl screws (12). Said screws make it possible to adjust the height of the platform, the trim of the plate (5) and also make it possible to adjust the distribution of the load between the various sensors. The base of the sensors is either left free on the bottom of the plate (4), or housed on the same bottom thanks to a slight recess, or glued. The two plates are joined together while allowing axial deformation of the sensors under the effect of a charge, to express themselves. The plate connection device (4) and (5) allows tightening in abutment or controlled tightening by means of one or more shouldered screws (13). /P
