ABSTRACT:
A portable sectional basketball floor that is quickly and easily assembled and disassembled. The floor comprises a plurality of interfitting panels. Certain panels on the periphery of the floor are rigidly secured together by bolted connections located below the playing surface. The internal panels are connected together by subsurface connections comprising overlying brackets with a vertical hole through each bracket. As the floor is assembled, the cooperating brackets on adjacent panels are slid over one another until the openings in the brackets are aligned. A pin is dropped into each pair of aligned holes from above to lock the floor panels together. When the sectional floor is removed, the pins are quickly and easily disengaged by simply lifting them with a magnet, thereby freeing the panels from one another.
