发明名称 Ball base construction and anchor
摘要 An improved base includes a base pad member having a flange plate attached to the bottom thereof for cooperation with a flat plate mounted on a post inserted in the ground. The base plate may thus slide onto the ground plate in order to retain the base in position. The base has a special oversized, generally rectangular construction so that a portion of the base projects beyond the first base foul line where it may be tagged by a runner. The remainder of the base is positioned inside the foul line in the normal base position for tagging by a fielder. The separate parts of the base are preferably denoted by distinctive color or design. This configuration promotes safety.
