<p>AN ELECTRIC STORAGE BATTERY ARRANGEMENT FOR USE IN ELECTRICALLY DRIVEN PROSTHETIC DEVICES An electric storage battery arrangement includes a frame which is to be mounted in the prosthetic device, and a storage battery which is insertable into the frame. A snap-holding arrangement holds the storage battery in the frame and includes a lever pivotable in the frame between a releasing and a holding position, being biased toward the releasing position and having one arm that holds the storage battery in the frame. Electric contacts are mounted on the lever, such contacts being arranged in the electric circuit of the drive of the prosthetic device and being in electric contact with the terminals of the storage battery when the latter is fully inserted in the frame. The lever has a pair of cylindrical projections received in a depression of the frame and held therein against displacement other than pivoting by an arraesting member connected to the frame. The storage battery has a centering recess intermediate the terminals, and another recess at the end spaced from the terminals, and a centering projection of the lever, and another projection of the frame, are received therein when the battery is at least partly inserted into the frame. A pressing member is urged into contact with the centering projection when received in the centering recess.</p> |
