Реферат: The trampoline has an upper curved panel (1) and a lower part (4), formed from bars. These are joined together at one end (12) and their other ends separate from each other. Between them there is a leaf spring (16) and a shock absorber (26), made of deformable elastic material, is fixed above its free end. Two coil springs (15), parallel to the leaf spring, are mounted between the front of the upper and lower parts and near their lateral edges. The shock absorber is more supple than the leaf spring.
