fig1 is a pictorial illustration of one example embodiment of a portable pitching mound . according to this example embodiment , it portable pitching mound comprises a first platform 10 , a second platform 40 , and a third platform 70 . a first cavity 20 is further included in this example embodiment of a portable pitching mound . the first cavity 20 is disposed beneath the first platform 10 . typically , this a first cavity 20 is in opposition to the first platform 10 . when the apparatus is in use , a user 15 stands upon the first platform 10 . the first cavity 20 provides an elevation 25 above the surface of the ground 85 upon which the portable pitching mound is positioned . typically , this elevation is approximately 8 to 10 inches , but this example elevation is not intended to limit the scope of the claims appended hereto . in some example embodiments , the first platform 10 is supported by one or more braces 80 disposed horizontally beneath the first platform 10 . typically , the one or more braces 80 are fixed to a cross braces 87 at one end of the first cavity 20 . this end 37 of the cavity 20 is typically left in an embodiment where the first cavity 20 is established by three risers 22 . one of the risers 22 closes the opposing end 35 of the first cavity 20 and the remaining two risers 22 are set substantially perpendicular 23 to the riser closing the end of the first cavity 20 . according to this example embodiment , a portable pitching mound further includes a second platform 40 . this second platform 40 is attached to the first platform 10 at a first pivot point 30 . directly underneath the second platform 40 , this example embodiment further includes a second cavity 50 . this second cavity 50 is formed by two risers 52 . in this example embodiment , the two risers 52 that form the second cavity 50 are tapered at an angle 120 so as to allow the second platform 40 to rest at a descending slope relative to the first platform 10 . a third platform 70 is also included in this example embodiment and is attached to the second platform 40 at a second pivot 60 . this third platform 70 , according to this example embodiment is supported by risers 100 , which are also tapered by a similar angle 110 so as to allow the third platform 70 to rest at substantially the same descending slope as the second platform 40 . this descending slope allows the user 15 to step downward through a pitching motion . fig2 is a pictorial illustration that depicts rotation of the third platform relative to the second platform of the described portable pitching mound . in this example embodiment , portability is achieved by allowing the third platform 70 to rotate 130 about the second pivot point 60 . the third platform 70 is rotated about the second pivot point 60 until it is fully enveloped within the second cavity 50 . fig3 is a pictorial illustration that depicts another aspect of portability of the present portable pitching mound . as can be seen in fig3 , the second platform 40 is allowed to rotate 150 about the first pivot 30 . in this configuration , the third platform 70 remains in a folded positioned and is contained within the second cavity 50 . accordingly , the second platform 40 and the third platform 70 are substantially parallel to each other and collectively rotate about the first pivot point 30 . this rotation 150 continues until both the second platform 40 and the third platform 70 are substantially contained within the first cavity 20 . fig4 is a pictorial illustration that depicts a fully folded configuration of the present portable pitching mound . in this fully folded configuration , the third platform 70 is typically contained within the first cavity 20 . the second platform 40 , according to one example embodiment , is also contained within the first cavity 20 . however , in one alternative example embodiment the second platform is disposed outside of the first cavity . in this alternative example embodiment , the second cavity 50 is typically substantially contained within the first cavity 20 . while this invention has been described in terms of several preferred embodiments , it is contemplated that alternatives , modifications , permutations , and equivalents thereof will become apparent to those skilled in the art upon a reading of the specification and study of the drawings . it is therefore intended that the true spirit and scope of the present invention include all such alternatives , modifications , permutations , and equivalents . some , but by no means all of the possible alternatives are described herein .
a portable pitching mound that includes three flat panels , sequentially attached to each other . the flat panels are pivotally attached to each other such that they fold in upon each other when not in use .
