ABSTRACT:
A central, length-delineated spine is formed by successive U shaped arms to which a pair of novel starting blocks can be attached, one on each side, and slid to such positions as desired by the runner. Each starting block is formed with a hollow open bottom side housing or box which will fit down over an anchorage block carried by successive U arms so as to lock the two together at a particular position along the spine. When raised free of such lockage, a starting block can be slid lengthwise due to (a) a pair of projecting lips or edge rails formed lengthwise along the starting block and along the hollow housing, and (b) composite slide rails formed by alignment of successive anchor blocks of a line of arms. Such starting blocks are easily raised and slid to new positions but cannot fall off the assembly (which might injure a foot) even if the assembly is inverted.
