ABSTRACT:
A breakaway safety base for use in baseball, softball, and other athletic base running games generally comprises a plate of metal or other suitable material, which is permanently secured to the underside of the base. The plate has a periphery with a plurality of downwardly turned edges, which engage the underlying ground. Generally vertical force on the base, as by a fielder or runner stepping on the base, results in the edges engaging the underlying surface more firmly, thereby resisting lateral displacement of the base. However, generally horizontal force on the base, as by a runner sliding into the base, allows the base to be horizontally displaced. This horizontal displacement of the base precludes any serious injury to the sliding base runner. The present breakaway safety base does not require any permanent anchor or other mating component to be permanently set or driven into the surface, thereby allowing the present safety base to be used to define any desirable base paths in any suitable playing field. The anchor plate may have three or more downwardly turned edges, with the edges being at an angle of less than, equal to, or more than 90 degrees to the main body of the plate. Preferably, the edges and corners of the depending anchor edge portions are smoothly rounded, in order to preclude injury to a player in the event of contact with one of the edges of the anchor after the base has been upset.
