Abstract:
1. A system for laying out a baseball diamond, comprising: a first base, a third base, and a pitching rubber; a home plate having a configuration of an irregular pentagon with a front end and a rear point, said home plate having a hole adjacent said rear point; a second base having a generally square top and four sides and an interior area therebetween, said second base having a reel in said interior area and a measuring tape coupled to said reel, said measuring tape having a distal end with a hook element, one said second base side having an opening to pass said measuring tape through, said second base having a center hole extending from said top through said interior area; wherein said reel is rotatable such that a first amount of said measuring tape is selectively withdrawn through said second base opening corresponding to a desired distance between said home plate and said second base; a first stake having a configuration that is complementary to a configuration of said home plate hole and that is selectively receivable therein, said first stake having means for being coupled to said hook element of said measure tape; a second stake having a configuration complementary to a configuration of said second base hole and that is selectively receivable therein; wherein said first and second stakes include a configuration that selectively pierces a ground surface; wherein said measuring tape includes an indicator associated with a predetermined placement of said pitching rubber when said measuring tape is extended between said home plate and said second base; wherein said reel is operable so that a second amount of said measuring tape is selectively withdrawn from said interior area through said second base opening and such that said second amount of said measuring tape is outside said interior area, said second amount of said measuring tape corresponding to the sum of a desired distance between said home plate and said first base and a desired distance between said first base and said second base; wherein said reel is rotatable about said second stake such that a corner base indicia on said measuring tape indicates a position at which said first base is to be positioned, said corner base indicia being viewable when said second amount of said measuring tape is outside said interior area and when said measuring tape is outstretched between said hook element coupled to said first stake and said corner base indicia and while said measuring tape is outstretched between said corner base indicia and said second base; and wherein said reel is rotatable about said second stake such that a corner base indicia on said measuring tape indicates a position at which said third base is to be positioned, said corner base indicia being viewable when said second amount of said measuring tape is outside said interior area and when said measuring tape is outstretched between said hook element coupled to said first stake and said corner base indicia and while said measuring tape is outstretched between said corner base indicia and said second base.
