skid material 58 , preferably grit , to increase friction between the system and the cheerleader during use . lastly , pilot holes 60 extend into the base plate in a concentric , circular configuration radially spaced from the shaft . the preferred number of pilot holes is eight . the pilot holes are adapted to receive and support elastomeric pads extending downwardly from the lower surface of the base plate to abate sliding of the system during use . the present invention is a cheerleader balancing and core strengthening , height - sensitive training system . it provides a safe , stable platform . it is preferably fabricated of high - strength extruded alloy t - 6063 aluminum , corrosion - dipped , electrostatic powder - coated for maximum durability . it is a safe and stable platform for an inexperienced beginner and cheerleaders in general which allows the building of skills at any level . it is stable , allowing the athlete to practice aligning his / her point of contact . the present invention has a non - skid top and rubberized foot to maintain solid contact with the shoe and floor at all times . it is ergonomically designed for weight to be distributed to outer perimeters of the foot for maximum weight distribution . the present invention is designed for portability allowing the cheerleader to train anywhere without needing assistance from a teammate . the design is unique and effective duplicating and replicating a cheerleader &# 39 ; s true motion of being lifted in the air . it allows a cheerleader to fine - tune his / her flying skills . it mimics being lifted by a teammate , making the user rely on only one foot , not both as if on the ground . it allows the athlete to use the other foot for making figures / stylistic movements / skills / stunts / acrobatic motion as is required in an actual performance . it allows cheerleaders to use either foot to balance their training on both sides of their body equally . it increases muscle - sensory and vertical - height awareness . it gives control and confidence to the athlete . the design is flexible . it can be accessorized with vinyl and decorative deals , allowing the cheerleader &# 39 ; s individuality to be expressed . teams can add their team colors . the present invention can be used as a seat while waiting . it can be used as a leg - stretching appratus , training leg - dips . two put together can be used to do deep push - ups . it can be used as a night / day stand , a shoe shining stool , a table - top , and a stepping stool . it is light weight making easy to carry . it is strong allowing a person of any size , i . e . coach / parent , to get on it to instruct and demonstrate a certain movement or pose . as to the manner of usage and operation of the present invention , the same should be apparent from the above description . accordingly , no further discussion relating to the manner of usage and operation will be provided . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
a vertically oriented shaft has a vertically oriented central axis . a lower plate has a configuration with an upper surface integrally formed with the lower end of the shaft . an upper plate has a geometric configuration with a periphery , a lower surface integrally formed with the upper end of the shaft , and an upper surface . a base plate has a center located on the central axis of the shaft . the base plate has an upper surface in facing contact with and separably coupled to the lower surface of the lower plate . the system has a reduced center of gravity for maximum safety , particularly for preteen users .
