Volleyball with one, two, three or four rebound elasticity enhancers

Abstract

Inside the hollow (4) elastic volleyball cap (5), an elastic piston (2) is connected to the volleyball flight section (1) in its inner area (6). A metal rebound enhancer (7) is pressed into the cylindrical tip (9) of the volleyball flight section. Likewise, another metal rebound enhancer (8) is pressed into the inner area (6) of the elastic piston (2). On the outside of the volleyball cap, there is another rebound enhancer (3) in the form of an aerodynamically shaped rubber ring (3) that further increases the rebound force. Between the end of the volleyball cap (5) and the flight section (1), another rebound enhancer in the form of an aerodynamic rubber ring (10) is attached.
