## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to training or practice equipment. It finds particular application in a baseball environment as a pitcher's mound and will be described with particular reference thereto. However, it is to be appreciated that the present invention is also amenable to other applications where a compact, portable ramp is desired.
Because practicing is a major component of excelling in any sport, it is critical to a player and coach to simulate accurate game-like conditions while practicing. Specifically, when practicing and warming-up for pitching, it is important for the player to be able to simulate the conditions and variables normally faced in game situations. One very critical component of the game of baseball is the pitcher's mound. The official rules of the game regulate the pitching mound dimensions corresponding to the sport and more specifically, the league of the sport being played. For example, the height of the pitching mound, the dimensions of the pitcher's rubber and even the slope of the front of the mound are just a few defined constants that are regulated by the official rules of the sport. When accurately reproduced on a practice field, the pitcher will become accustomed to game-like conditions thus focusing on perfecting the mechanics of the art of pitching.
Whether due to darkness, winter seasons or inclement weather, many times, actual outdoor field practice is prohibited. Sometimes when outdoor practice is not practical, it is possible to practice indoors. However, practicing indoors is generally not conducive to replicating game-like conditions as the regulation pitching mound is usually not available indoors.
Prior art workers have devised many types of portable pitching mounds. For the most part, the prior art portable pitching mounds comprise bulky molded fiberglass shells in part, at least, covered with a resilient material, an artificial turf material, or the like. Examples of such mounds are taught in U.S. Pat. Nos. 4,306,718 and 4,749,223.
The present invention overcomes problems in the prior art and others.

Referring to FIG. 1, a portable pitching mound generally indicated by reference number 100 includes a base unit 102, a pitching rubber 104 and a collapsible ramp 106 constructed of multiple individual sections 108, 110.
The base unit 102 is preferably rectangular in shape. In one embodiment, dimension A is 76 centimeters (30 inches). The width of the base unit 102, dimension B, of the present embodiment is 84 centimeters (33 inches). It is understood that the dimensions of the base unit 102 may vary without changing the scope of the invention.
The base unit 102 is constructed from a lightweight plastic material. Alternatively, it is contemplated that the base unit 102 may be constructed from other suitable materials including, but not limited to, rubber, fiberglass, polymer, wood, metal, metal alloy and the like. It is further contemplated that the base unit 102 may be rubber coated irrespective of the base construction material used.
Referring again to FIG. 1, the base unit 102 includes a handle 112 to increase the portability of the pitching mound when in the stored position. As illustrated, handle 112 is a suitcase type handle protruding from a sidewall of the base unit 102. However, it is contemplated that the location of handle 112 may vary. It is further contemplated that the type of handle may vary in size and type from the suitcase type handle 112 illustrated in FIG. 1. For example, collapsible handles, carrying straps, cutouts, indented grips and the like may be used in place of handle 112 to effectuate the portability of the pitching mound. Moreover while the embodiment of FIG. 1 includes only one handle 112, it is contemplated that additional handles or straps may be disposed in a variety of sizes and locations on the base unit 102 to increase the mobility of the pitching mound.
As illustrated, a pitching rubber 104 is adjustably connected to the upper surface of the base unit 102. For example, in youth league rules, the pitching rubber 104 has a dimension C of 10 centimeters (4 inches) and a dimension D of 46 centimeters (18 inches). Additionally, the pitching rubber 104 is preferably adjustably mounted with a dimension E of 30 centimeters (12 inches). Alternatively, it is contemplated that the pitching rubber 104 is interchangeable with pitching rubbers of different sizes in order to comply with the rules of the specific sport and league. For example, the dimensional size of the pitching rubber 104 may vary from the youth league pitching rubber discussed above to a professional league pitching rubber which has a C dimension of 15 centimeters (6 inches) and a D dimension of 61 centimeters (24 inches). Additionally, pitching rubber 104 is adjustable thus increasing or decreasing dimension E in order to further adapt to the rules of the specific sport and league being played, for example softball, baseball, kickball and the like.
Further, the preferred embodiment includes a pitching rubber 104 constructed of a rubber or fiberglass core with a solid molded rubber cover. Alternatively, it is contemplated that the core of pitching rubber 104 may be constructed of different materials including, but not limited to, rubber, fiberglass, polymer, wood, metal, metal alloy and the like.
As shown in FIG. 1, the height F between the mounting surface of base unit 102 to the top of the pitching rubber 104 is variable to simulate various conditions and to comply with the rules of the specific sport and league being played. Continuing with the example, overall height F is 15 centimeters (6 inches) which is the official height for youth league baseball. It is contemplated that the overall height F can be adjusted to accommodate all sports and leagues as well as future league rule changes.
In one embodiment, height F is selected via adjusters 114 that may be extended or retracted to level the pitching mound as well as maintain height F. Adjusters 114 are threaded into a complimentary shaped part of base unit 102 or upper ramp section 108. One ordinarily skilled in the art can appreciate that these adjusters 114 could be replaced other devices known or to be discovered in the art including, but not limited to, spacers, spring loaded adjusters, pinned units and the like. Additionally, adjusters 114 are equipped with spikes 116 to secure the portable pitching mound to a playing surface. It is contemplated and understood that the spikes 116 could be replaced with other known or to be discovered anchoring means including non-slip pads, weighted feet and the like.
Continuing to refer to FIG. 1, the collapsible ramp 106 comprises two individual ramp sections, an upper ramp section 108 and a lower ramp section 110. Those skilled in the art will appreciate that this collapsible functionality allows the ramp 106 to reduce in length permitting the lower ramp section 110 to be received in the base unit 102 for storage while the upper ramp section 108 fits on top of the base unit 102 forming a lid. Alternately, lower ramp section 110 may be received into upper ramp section 108 for storage. In either case, the upper ramp section 108 of the preferred embodiment has dimensions A′ and B′ generally corresponding to dimensions A and B respectively of the base unit as described above.
The upper ramp section 108 includes two removable braces 118 disposed on the under side of the upper ramp section 108. As shown in FIG. 1, the braces 118 are equipped with adjusters 114 as described above. These braces 118 support the collapsible ramp from the pitcher's physical weight. Alternatively, the braces 118 can be disposed on the lower ramp section 110 or at an interface between the upper and lower sections.
FIG. 2 illustrates a mound 200 having an upper ramp section 108 and a lower ramp section 110 connected together utilizing a tongue-and-groove connecting arrangement. Lower ramp section 110 includes a tapered or angled portion 210 on one end to facilitate uniform contact with the ground or surface on which the pitching mound rests. The opposite end of lower ramp section 110 includes the tongue portion 220 of the tongue-and-groove connecting arrangement. Also as shown in FIG. 2, the mating end of the upper ramp section 108 includes the groove portion 230 of the tongue-and-groove connecting arrangement. Once the two sections are physically connected forming the tongue-and-groove bond, pinholes 120 are aligned between the sections. Pins 240 are inserted through the pinholes 120 to secure the bond between the ramp sections thus forming continuity between the sections. Although the illustrated embodiment utilizes the tongue-and-groove technique of connecting the ramp sections, it is contemplated that additional connecting techniques could be used to form a continuous slope from the multiple ramp sections 108, 110. Artisans can appreciate that lower ramp section 110 may alternatively be press-fit, snapped, Velcroed, pinned and the like to upper ramp section 108.
Continued reference to FIG. 2 illustrates the same pinned arrangement to secure the upper portion 250 of the upper ramp section 108 to the base unit 102. Once the upper ramp section 108 is physically connected to the base unit 102 as shown in FIG. 2, the pinholes 120 are aligned between the sections. Pins 240 are inserted through the pinholes 120 to secure the bond between the sections. Although the preferred embodiment utilizes the pinning technique of connecting the upper ramp section 108 to the base unit 102, it is contemplated that additional connecting techniques could be used to lock the sections together. In other embodiments, the upper ramp section 108 is press-fit, snapped, Velcroed and the like to bond the connection. One skilled in the art can appreciate the numerous techniques of connecting the upper ramp section 108 to the base unit 102.
Although two ramp sections are illustrated, it is contemplated that the slope could be formed utilizing any number of collapsible ramp sections. In the alternative embodiments, the ramp sections may utilize the same locking arrangement as described herein. Additionally, all connecting arrangements described herein may be utilized regardless of the number of ramp sections included.
Now referring to FIG. 3 and as previously described herein, a lid 310 to base unit 102 is created by the upper ramp section 108 when the collapsible ramp is in the stored position. Continued reference to FIG. 3 shows that the base unit 102 of the preferred embodiment includes a measuring device 320 to accurately measure distances when assembling and setting up the pitching mound 100 on a playing surface. The measuring device 320 includes a measurement tape 330 that includes distance measurements corresponding to different sports and/or leagues.
In one embodiment, the measuring device 320 includes a conventional measuring tape 330 with at least 15.25 meters (50 feet) of retractable measuring tape. The measuring device may be manually rewindable, spring-loaded or otherwise retractable as is known to those skilled in the art. The measuring device 320 and measuring tape 330 enables accurate distancing of the portable pitching mound during set-up.
Referring to FIG. 4, the measuring tape 330 includes distance markings 450 that correspond to different sports and/or leagues. Moreover, other types of measuring equipment may be substituted with no loss of functionality, such as laser range finders, pre-measured string colored to indicate various distances and the like.
Continued reference to FIG. 4 shows the relationship of a base, such as a home plate 460 to the pitching rubber 104 in a standard set-up. Those skilled in the art will appreciate that the desired distance between the pitching rubber 104 and home plate 460 as depicted by distance G of FIG. 4 is variable and corresponds to the sport and league of the particular sport. For example, the pitching distance G measured from the front of the pitching rubber 104 to home plate 460 for a full-sized field (ages 13 and up) is 18.44 meters (60 feet 6 inches). Alternatively, the distance G is decreased to usually 14.2 meters (46 feet) for players of the age of 9 or 10. As shown in FIG. 4, the home plate 460 is equipped with a cut-out 470 capable of receiving one end of the measuring tape 330 to secure the tape while setting up the pitching mound adjustable to any length and height.
Now referring to FIG. 5, home plate 460 stores on the underside of the base unit 102. The home plate 460 includes Velcro which mates to Velcro on the underside of the base unit 102 causing the home plate 460 to be removably attached. One skilled in the art can appreciate that other forms of attaching may be utilized including, but not limited to, press-fit, snaps, guide rails and the like.
Another embodiment illustrated by FIG. 6 shows that lower ramp section 110′ may be permanently hinged to upper ramp section 108′ allowing the collapsible ramp to fold onto itself for storage. In this embodiment, the lower ramp section 110′ is connected to the upper ramp section 108′ by a hinge 610. Similarly, upper ramp section 108′ is connected to the base unit 102′ by a hinge 620. In this embodiment, the lower ramp section 110′ is hinged onto the upper ramp section 108′. The upper ramp section 108′ is then folded onto the top of the base unit 102 to form a lid on the base unit 102′ as shown in as previously described and illustrated in FIG. 3.
As illustrated by FIG. 7, an optional adapter 710 connects to the base unit 102 opposite the collapsible ramp 108, 110. The adapter 710 creates additional area on the pitching surface to compensate for taller users. An L-shaped locking mechanism 720 is used to connect the adapter 710 to the base unit 102. Although an L-shaped locking mechanism 720 is illustrated, one ordinarily skilled in the art would appreciate that other attachment mechanisms may be used to fix the adapter 710 to the base unit 102.
The invention has been described with reference to the preferred embodiments and selected alternate embodiments. Modifications and alterations will become apparent to persons ordinarily skilled in the art upon reading and understanding the preceding detailed description of the invention. It is intended that the invention be construed as including all such alterations and modifications insofar as they come within the scope of the appended claims or the equivalence thereof.
