  Description   Spacial model according to Otto Fischer to demonstrate the movement of the walking man. The model presents the successive positions of the longitudinal axis of the single parts of the arms and legs and the head parietal suture in 21 phases of movement during one double step. At the same time it demonstrates the doubled curved lines describing the centre of the hip-, knee-, food-, shoulder-, elbow- and hand-joint and the head vertex. The hand is supposed to be fixed with the forearm. The time interval between to successive phases of movement is exactly 1/20 seconds; for a better overview and counting of the connected positions of the singular extremities the 1., 6., 11., 16. and 21. phase are marked by yellow threads, whereas the other threads are red. The model is easily surveyed and serves for presentations very well. In 1/10 life size, with etwee; 1,400 kg.
