<p>The object of the present invention is a device by means of which simulation of the lengthening of shortening of, for example, a limb is obtaining by construction of a telescoping structure (3), (9), the mutual sliding of which, and therefore the lengthening or shortening is controlled by means of threads (4) that are rolled or unrolled from a disk shaped like one or more side-by-side pulleys (5). Thanks also to the action of a counteracting spring (2). The movement of the spools is controlled by a circuit (7) that registers shaking and therefore playing with the toy according to the equation, more playing = more growth (that is, more shaking more growth).</p> |
