ABSTRACT:
A portable volleyball net assembly characterized by a vertically-adjustable net which is continuously supported along the edges by net cylinders or rods engaging a pair of net support poles stabilized vertically by tensioning cords. In a first embodiment the assembly includes an elongated, rectangular net, each vertical edge of which is secured along the entire length by means of a binder or sleeve to a tubular net cylinder which slidably receives a net support pole assembled from three tubular support members attached by connecting joints. The net cylinders and net are vertically supported by friction or by adjusting pins which are extended through pin openings provided in each net support pole. A tensioning cord vertically stabilizes each net support pole and is fastened at one end to a stake in the ground, while the other end loops through a clevis mounted on the top of the net support pole. In a second embodiment each net cylinder is secured to a pair of spaced support rings or cylinders which slidably receive the upper end of a corresponding net support pole. The net can be vertically adjustably supported either by friction or by using the adjusting pins as in the previous embodiment or by using a loop-pile stay which wraps around the net support pole and each corresponding net cylinder.
