[ What the invention claimed is:] [1.] A combination of sports game apparatus adapted to be alternatively arranged into a framework for a net assembly for badminton or tennis, a framework for a goal for soccer or hockey, or a framework for a back stop for basketball, comprised of a plurality of U-blocks, a plurality of triangle blocks, a plurality of elongated tubes, a plurality of L-bars, a plurality of angle connectors, and a plurality of coupling tubes, wherein:each of said U-blocks comprises an elongated block body and two crossed plug members perpendicularly raised from said elongated block body and disposed in parallel;each of said triangle blocks comprises a first circular through hole, a second circular through hole, a third circular through hole and a fourth circular through hole vertically disposed through top and bottom sides thereof, two circular plug holes horizontally and bilaterally disposed at one lateral side thereof, and a semicircular vertical groove disposed between said circular plug holes, said first circular through hole and said third circular through hole as well as said second circular through hole and said fourth circular through hole being respectively arranged in a diagonal manner, said second circular through hole having a first symmetrical pair of vertical grooves and a second symmetrical pair of vertical grooves longitudinally disposed at the periphery, said fourth circular through hole having a first symmetrical pair of vertical grooves and a second symmetrical pair of vertical grooves longitudinally disposed at the periphery, the radial line between the first symmetrical pair of vertical grooves of said second circular through hole and the radial line between the first symmetrical pair of vertical grooves of said fourth circular through hole being disposed in parallel to the diagonal line between said first circular through hole and said third circular through hole, the line which passes through the first symmetrical pair of vertical grooves of said second circular through hole and the line which passes through the first symmetrical pair of vertical grooves of said fourth circular through hole intersecting each other, the diagonal line between said second circular through hole and said fourth circular through hole being disposed in parallel to the lateral side at which said circular plug holes and semicircular vertical groove are disposed;each of said elongated tubes has an outer diameter fitting the diameter of the circular plug holes of said triangle blocks, and two symmetrical pairs of radial pin holes near two opposite ends thereof;each of said L-bars comprises an elongated, flat base, an upright stub tube raised from one end of said flat base and having two longitudinal ribs raised from the periphery at two opposite side, a plurality of transverse teeth disposed at an opposite end of said flat base, and two circular through holes spaced between said upright stub tube and said transverse teeth and adapted for receiving the two crossed plug members of one of said U-blocks, said upright stub tube being adapted for coupling to the second circular through hole or fourth circular through hole of one of said triangle blocks, the line which passes the longitudinal ribs of said upright stub tube being disposed in parallel to the longitudinal central axis of said flat base, the longitudinal ribs of said upright stub tube being adapted for engaging the first symmetrical pair of vertical grooves or second symmetrical pair of vertical grooves of the second circular through hole or fourth circular through hole of one of said triangle blocks, the inner diameter of the upright stub tube of each of said L-bars fitting the outer diameter of each of said elongated tubes so that one elongated tube can be plugged into the upright stub tube of one L-bar;each of said angle connectors is a hollow, about 150.degree. angle plate of U-shaped cross section adapted for connecting two L-bars together, having a plurality of transverse teeth at an inner side for engagement with the transverse teeth of one of said L-bars;each of said coupling tubes comprises an annular flange raised around the periphery and equally spaced from two opposite ends thereof, two sets of longitudinal ribs respectively raised from the periphery and extended from the annular flange to its two opposite ends, and two symmetrical pairs of radial pin holes near its two opposite ends corresponding to the radial pin holes of said elongated tubes.
