CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority benefit of U.S. provisional patent application No. 63/129,141 filed Dec. 22, 2020, entitled “Forms And Methods For Constructing A Pitching Mound For Use On A Synthetic Turf Field,” which application is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to pitching mounds, and more particularly to forms and methods for constructing pitching mounds for supporting a pitcher's rubber playing baseball or softball on a synthetic turf field.

BACKGROUND

A pitching mound is a raised section in the middle of a baseball diamond where a pitcher stands to throw a pitch. A pitching mound is typically made of clay, sand, and dirt.

On synthetic turf baseball diamonds, typically a handmade wooden form is fabricated having a lower circular peripheral edge and a raised center. The form is filled with concrete. Once the concrete is cured, the form is then overlaid with synthetic turf to form the pitching mound. In another approach, without using a form, some contractors will shape the mound using stone, which is then compacted and overlaid with synthetic turf.

Conventional portable pitching mounds have also been used on flat surfaces. The portable pitching mounds may be a single unit or may be assembled from a plurality of sections.

SUMMARY

Shortcomings of the prior art are overcome and additional advantages are provided through the provision of a method for forming a pitching mound for supporting a pitcher's rubber for playing baseball or softball on a synthetic turf field. The method includes, for example, assembling a pitching mound form from a plurality of prefabricated frame sections, each of the plurality of prefabricated frame sections defining a hollow frame and one of the plurality of prefabricated frame sections comprising a pitcher's rubber frame for receiving the pitcher's rubber, positioning the assembled pitching mound form on a support structure for the synthetic turf, placing uncured concrete in the hollow frames of the assembled pitching mound form and around the pitcher's rubber frame, forming an upper surface of the uncured concrete in the assembled pitching mound form around the pitcher's rubber frame, and placing synthetic turf over the cured concrete filled assembled pitching mound form.

In another embodiment, a pitching mound form is fillable with concrete for constructing a pitching mound for supporting a pitcher's rubber. The pitching mound form includes, for example, a plurality of prefabricated frame sections, each of the plurality of prefabricated frame sections comprising a hollow frame having an open upper surface and an open lower surface, and one of the plurality of prefabricated frame sections comprises a pitcher's rubber frame for receiving the pitcher's rubber.

In addition, the peripheral frame sections and center frame section may be configured to have tongue or groove type features or tabs and notches for operably connecting the various frame sections together.

FIGS. 10-18 diagrammatically illustrate a method for installing baseball pitching mound form 10 for constructing a baseball pitching mound and securing a pitcher's rubber in a synthetic turf of a baseball diamond for playing the game of baseball, according to an embodiment of the present disclosure.

Initially, as shown in FIGS. 10 and 11, profile guide members 20 are bolted to prefabricated center frame section 100 at corresponding hole locations using connection hardware such as bolts and nuts.

With reference to FIG. 12, project specific drawings may be checked to determine the field location for the assembled center frame section 100 and profile guide members 20 on a support structure 12 such as the ground or a layer of stone. As shown in FIG. 12, the location of center frame section 100 is set such that the inner front edge 188 of pitcher's rubber frame 180 for receiving the pitching rubber will fall 60 feet and 6 inches from the apex of a home plate (not shown) in the direction of arrow A, along with ensuring that the major sides of center frame section 100 are parallel to the sides of the home plate. In some embodiments, the ground 12 may be prepped and leveled to provide a level surface on which the assembled center frame section 100 and profile guide members 20 are placed. The appropriate installation elevation may be achieved by excavating or site preparation in a suitable manner.

As shown in FIG. 13, four prefabricated peripheral frame sections 200, 300, 400, and 500 are aligned with center frame section 100, and operably bolted together at the various alignable hole locations using connection hardware as shown in FIG. 14. The assembled pitching mound form, as shown in FIG. 14, is staked in place by driving ½ inch rebar through provided holes in the plurality of the horizontal cross-members of the peripheral frame sections, for example, regarding outer frame section 200 installed through holes 272 in the web of cross-member 270 and installed through holes 282 in the web of cross-member 280. The rebar may have an upper end having an enlarged head, L-shape, or curved hook shape. The rebar stakes may be about 1 foot to about 2 feet long. In some embodiments, horizontal rebar may be positioned across and laid on top of or in notches in the cross-members. In other embodiments, a mesh may be disposed on top of the cross-members. As shown in FIG. 15, the remaining profile guide members 22 and 24 are operably installed, for example, bolted at one end to center frame section 100 and bolted at the other end to a corresponding cross-member adjacent to the arcuate sides. The distal ends of profile guides 20 may be operably attached the peripheral frame sections adjacent to the arcuate side.

As shown in FIG. 16, uncured concrete 600 is poured into or placed in the center frame section 100 and peripheral frame sections 200, 300, 400, and 500 of the assembled baseball pitching mound form 10. The upper edges 212, 312, 412, and 512 of arcuate members 200, 300, 400, and 500, the upper surfaces of profile guide members 20, 22, and 24, and the upper surfaces of the side members and cross-members of center frame 100 allow for installation personnel to screed or pass a leveling device over the uncured concrete to provide a level and/or even uncured concrete surface that tapers from the center frame outwardly towards upper edges 212, 312, 412, and 512 of arcuate members 200, 300, 400, and 500, respectively. The concrete is allowed to cure and harden so that the center frame section and the peripheral frame sections are anchored to the ground. It will be appreciated that the assembled baseball pitching mound form is configured to have sufficient strength to maintain it shape when filled with the uncured concrete.

The space around the outside of the arcuate sides 210, 310, 410, and 510 of the peripheral frame sections may be back filled with stone 13 to the top of the arcuate sides. In some embodiments, the backfilling with stone around the perimeter of the assembled baseball pitching mound form may be performed before the concrete is poured and cured.

With reference to FIG. 17, once the concrete 600 has been placed and cured, a synthetic turf 650, a portion of which is shown in FIG. 17, can be cut and secured over the baseball pitching mound form 10 with the cured concrete 600.

As shown in FIG. 18, synthetic turf 650 may be disposed over and secured to the upper surfaces of flanges 185 and 187 of pitcher's rubber frame 180, and/or tucked into the pitching rubber cavity such as disposed over and secured to the inner surface of legs 182 and 183. For example, synthetic turf 650 may be secured to the inside vertical side of pitcher's rubber frame 180 with self-tapping screws. In some embodiments, depending on the thickness of the synthetic turf or the density of the fibers or “thatch layer,” the synthetic turf fibers of the synthetic turf may be shaved down as necessary during this step to allow for clearance for receiving a pitcher's rubber 11. By securing the synthetic turf inside the inner frame, a friction fit may be achieved with pitcher's rubber 11. The pitcher's rubber may be a standard pitcher's rubber. For example, the pitcher's rubber may be a replaceable SHBBPB Schutt Four-Sided Professional Pitching Rubber. With reference still to FIG. 18, a pitcher's rubber height can be adjusted as needed by adjusting the height of adjustable supports 189, for example, adjusting threaded members or bolts. For example, the adjustable supports may be ⅜ inch treaded studs and bolts.

In other embodiments, the synthetic turf may include a horizontal lip that borders the cavity for the pitcher's rubber, such that the synthetic turf will be fastened to the upper flanges surrounding the cavity using an adhesive and/or fasteners such as self-tapping screws.

With reference to FIG. 19, in some embodiments, a synthetic turf 670 may include a stand-alone replaceable rectangular synthetic turf portion 675. The attachment of the replaceable rectangular portion 675 may be secured adjacent to the pitcher's rubber as described above. Since replaceable rectangular portion 675 is in a high wear area, the replaceable rectangular portion 675 can be replaced without the need to replace the remainder of the synthetic turf 670 that is disposed over the pitching mound. In other embodiments, a rubble layer 660 may be disposed between the cured concrete and the synthetic turf 650 of the installed pitching mound form, or under the replaceable rectangular synthetic turf portion 675. The rubber layer may extend over the entire outer frame section.

For example, center frame section 100 may have a length of about 106 inches and a width of about 60 inches. The outside diameter of the pitcher's mound form 10 may be about 18 feet.
