the subpanels the top and bottom sides of spline 128 are formed with teeth sized to interlock with the teeth formed in the keyway recess the side perimeter edges of the subpanels which abut along the center dividing line below the net are releasably held together by pushing base member 126 inwardly so that the male spline releasably locks with the keyway channels net post bracket 124 is formed at its upper end with a slot 130 through which the upper net string 132 is reeved an opening 134 is formed at the lower end of the bracket for guiding the lower net string 136 a hook 138 on the outer edge of the bracket is provided for tying up the net strings so that the net can be drawn taut fig1 17 illustrate table tennis apparatus 20 converted to its single play configuration for this configuration the additional elements required include a pair of 34 t 34 shaped splines 140 142 and a pair of triangular corner locks 144 146 spline 140 is typical and is shown in detail in fig1 it is comprised of an elongate body formed with upper and lower male splines 148 150 and an outwardly extending center male spline 152 each of the three male splines are sized and shaped commensurate with the keyway recesses in the peripheral edges of the respective table subpanels 32 64 and center leg panel 78 the sidewalls of each of the splines are formed with elongate parallel teeth 154 which are adapted to interlock with the teeth formed internally within the keyway recesses triangular corner lock 144 is typical and is comprised of a generally triangular shaped flat plate 156 having a vertical edge and horizontal.
