The balance beam of this invention has an elongated beam member having opposite ends, a center portion, a top and a bottom, with legs on the bottom thereof adjacent the ends. Each leg has an upper and a lower end. A resilient support and trolley assembly is mounted within the elongated beam adjacent the ends thereof with each support assembly having a depending arm member extending downwardly therefrom with each arm member being pivotally secured to one of the upper ends of the legs. The legs extend downwardly and outwardly from the arm member in the plane of the beam member so that the lower ends thereof dwell substantially under the ends of the beam member. Elongated links are pivotally secured by their ends to one end of the beam and one end of each of the legs to hold the beam member in an erected elevated horizontal position. The resilient support and trolley assembly is longitudinally movably positioned within the beam and has two end blocks rigidly secured to a trolley. An intermediate block is slidably mounted between the end blocks and is associated with the arm member. A resilient element is located between the intermediate block and the end block nearest the center portion of the beam member so that when a vertical force is applied downwardly on the top of the beam, the resilient element will yieldingly resist the sliding of the intermediate block towards the center portion. The resilient element moves on an inclined plane, and is associated with a pair of tension springs which connect the support assembly to the beam.

A clamp for securing a vertically disposed elongated antenna to the horizontal edge of a volleyball net has a base wall and an oppositely disposed spaced clamping wall secured together at adjacent edges by a U-shaped live hinged portion. The clamping wall extends in a tapered direction towards the base wall to define a narrowed net receiving access lot opposite to the live hinge portion. A vertically disposed shoulder extends outwardly from an outer surface of the base wall, and a vertical bore is located in the shoulder to receive an end of an elongated antenna. The clamp members are comprised of a single piece of plastic material. An elongated lift member is on an elongated horizontal free edge of the clamping wall and extends outwardly from the access slot. A plurality of serrations are formed on an inner surface of the base wall opposite to the clamping wall. The shoulder on said base wall has a vertical length greater than the vertical height of the base wall.
