发明名称 Infield Set Up Device
摘要 A device and a method for accurately laying out the bases of an infield, said device comprising marking pieces that attach to one another to form a single integrated unit. Base marking pieces forming the integrated unit may mark the positions of the bases of an infield. The marking pieces may be connected, which connecting means may assist in measuring distances between marking pieces, which measured distances may determine proper positions of the base marking pieces. After bases are laid out and an infield set up, the marking pieces may re-attach to again form the integrated unit.;In one embodiment, accuracy may be increased by utilizing a center reference point marked by a center marking piece. The center marking piece may be connected to some base marking pieces, and in one embodiment the base marking pieces may attach to the center marking piece and together form the integrated unit.

主权项 1. A device for setting up positions for first, second, third and home bases on an infield having a center point defining a center of the four bases, said device comprising: An integrated unit comprising a center marking piece adapted to be positioned at the center point of the infield attachable to four base marking pieces adapted to define the positions of respective bases of the infield from the center point, each base marking piece being attached to the center marking piece by a first reeled cord that is unwindable to a predetermined center-to-base total length connecting between the base marking piece and the center marking piece to define the position of the respective base from the center point, and is rewindable to bring the base marking piece for reattachment to the center marking piece to form the integrated unit.
