Combination of Sports Game Apparatus

The present invention relates to a combination of sports game apparatus which can be rapidly 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.

When to play a particular ball game, people shall have to go to a particular court, field or place where the requisite facilities are available. For example, when to play the game of basketball, people shall have to go to a basketball court, or a place where a back stop is available. Further, the residents of a building or buildings may play games in a nearby open field or yard. However, the residents of a building or buildings cannot play a variety of ball games in the surrounding field due to the limitation of limited open space and the lack of requisite facilities.

Each elongated tube 3 has an outer diameter fitting the diameter of the circular plug holes 25;26 of the triangle blocks 2, and two symmetrical pairs of radial pin holes 31;32 near its two opposite ends. Each L-bar 4 comprises an elongated, flat base 41, an upright stub tube 441 raised from one end of the flat base 41 and having two longitudinal ribs 441;442 raised from the periphery at two opposite side, a plurality of transverse teeth 45 disposed at an opposite end of the flat base 41, and two circular through holes 42;43 spaced between the upright stub tube 441 and the transverse teeth 45 and adapted for receiving the two crossed plug members 12;13 of the U-block 1. The upright stub tube 44 is adapted for coupling to the second circular through hole 22 or fourth circular through hole 24 of one triangle block 2. The line which passes the longitudinal ribs 441;442 is disposed in parallel to the longitudinal central axis of the flat base 41. When the upright stub tube 44 is plugged into the second circular through hole 22 or fourth circular through hole 24 of one triangle block 2, the longitudinal ribs 441;442 are forced into engagement with the first symmetrical pair of vertical grooves 221;222 (241;242) or second symmetrical pair of vertical grooves 223;224 (242;244) of the circular through hole 22 (24) of the corresponding triangle block 2. The inner diameter of the upright stub tube 44 of each L-bar 4 fits the outer diameter of each elongated tube 3 so that one elongated tube 3 can be plugged into the upright stub tube 44 of one L-bar 4. Each angle connector 5 is a hollow, about 150.degree. angle plate of U-shaped cross section adapted for connecting two L-bars 4 together, having a plurality of transverse teeth 51 at an inner side for engagement with the transverse teeth 45 of one L-bar 4.
