ABSTRACT:
A balance beam 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 assembly is mounted within the elongated beam adjacent the ends thereof with each support assembly having a depending clevis extending downwardly therefrom with each clevis being pivotally secured to one of the upper ends of the legs. The legs extend downwardly and outwardly from the support assembly 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. Each leg has an upper portion that extends downwardly and outwardly from the clevis, and a lower portion that extends downwardly and outwardly from the upper portion, with the upper and lower portions having center axes forming an obtuse angle with respect to each other. The resilient support assembly is positioned within the beam and has two end blocks rigidly secured to the beam. An intermediate block is slidably mounted between the end blocks and is associated with the clevis. The 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 legs on the beam are vertically adjustable and have an assist spring interposed between telescoping portions of the legs to assist the lifting of the beam during the height adjustment process.
