This patent contains figures and images illustrating the invention and its embodiment.
A tennis player needs multiple playing racquets available for their use, and the mass proportions of every racquet in their bag needs to match, otherwise players will likely experience a degradation of their swing mechanics, BOC provides an accurate measurement of player racquets mass proportions by comparator testing of any 2 racquets, thus providing a simplified solution for accurate measurement, and then equalization process of player racquets mass proportions.
1. A balance opposition comparator apparatus for measuring comparative mass moments of two massive handles, comprising:
a stationary vertical base structure pivotally coupled to a beam; an angle indicator configured to measure an angularity of said beam; a pair of inlet grips configured to retain the two massive handles, respectively, each inlet grip located on a distal side of the beam, each inlet grip being equidistant from a center pivot axle of the beam; wherein the two massive handles are gripped and laying horizontal when loaded into respective inlet grips for testing and are equally exposed to gravity forces acting perpendicular thereto for comparator testing; wherein any differential in mass moments present between the two massive handles causes pivotal rotation of the beam; wherein the degree of angularity is indicative of the magnitude of unequal mass moments present between the two gripped massive handles and when no differential of mass moments detected between the two massive handles, the beam will remain in a normal horizontal position.
11. A balance opposition comparator apparatus for measuring comparative mass moments of two massive handles, comprising:
Racquet balance adjustment scale Mass moments measurement scale Quality Control tool Base ball Bat proportions measure Golf club swing mass scale
A perfect for use: Tennis racquet/Golf club/Ball bat/etc. requires proper proportional balance/mass distribution to perform properly.
Typically manufactured racquets/etc. rarely meet their exact intended proportional balance specifications at sale due to MFG. build tolerances so consumers end up with many deficient for use racquets/etc. that need some degree of mass proportion modification to be perfectly balanced for use.
STATE OF THE ART
With current tools it is fairly impossible to determine the mass distribution of within a tennis racquets frame/etc. other than perhaps X RAY or MRI of cross section. Estimates can be made using a basic balance board or dynamic swing weight scale or total mass can be measured on digital scale again this will not indicate exactly where massive areas are located. Where any racquet is more or less massive within it's frame is not possible to measure directly.
Some other inventions for the measurement of swing weight in golf clubs have been introduced and are currently available from RALPH MALTBY and KENITH SMITH They also use gravity force motive in a mass balance system that uses a weight bias movable slide mounted on a pivot-able beam with an engraved measurement scale used as a variable swing mass reference to then balance against as it is opposed by the mass-moment of a golf club griped to and laying perpendicular to gravity at distal end of pivot-able beam having central pivot. The device calibration gives a swing wt. figure when balanced as a final measurement. A tennis related similar use scale is a simple balance board having a raised horizontal pivot rod that the tested objects frame lays atop and object then moved sideways until a balance position is found where it remains in horizontal plane point of balance can then be measured. Also electronic swing wt. devices by Babolat and Prince MFG. co. can perform swing mass measure within some tolerance +− accuracy unknown but whatever it is likely it will not be as accurate as direct comparison measurement or as easy to confirm accurate swing matching from one frame to another frame or to make the small mass adjustments required for matching with an active indicator scale or modify a swing mass balance toward an exact match with the preferred balance of a reference massive object/racquet/etc. These noted inventions while similar in some function are not comparators of mass proportions so they can not directly determine swing mass matching of one mass-moment object directly compared against a similar reference mass-moment object.

A typical weight comparator scale only compares an objects center mass no size proportions or moments are measured so our scale by its unique tested object mounting configuration does much more interrogation of a tested objects massive proportion quantities.
BOC scale orients the tested objects length/maximum moments perpendicular with gravity so that all the infinite individual moments of included mass will all be measured as one gravity motive force then said one force is compared to a tested 2nd objects one force as placed in opposition then both 2 forces counteract in beam assembly causing each tested objects equal forces to cancel out the others leaving either no force acting to rotate beam or some differential force that acts to cause beam rotation angularity that's relative to some massive mismatch between the 2 tested objects massive proportions.
Moreover BOC Indicates static swing mass moments of sports implements/Racquets/Clubs/Bats/etc., via comparison to a reference object having a known quantity mass-moment said ref. object is opposed mounted to counteract with the tested 2nd massive object resulting in any as equal counter-forces nullification then if both tested massive objects were of equal mass-moments scale will indicate on center force equality and since you know the reference objects massive quantities you now know the tested 2nd objects mass quantities as well swing mass/mass proportions/total mass. Furthermore: in above if there were instead some non countered differential mass forces remaining after nullification of all equal opposed forces they would cause an unbalanced rotational condition and pointer would indicate +− out of center scale meaning tested 2nd object mass proportions do not match the reference object then one can make some adjustments to mass proportions on tested 2nd objects frame to bring scale reading toward center scale where both objects would finally read as equal.
Provides that during comparison testing you can match the 2 tested objects massive proportions more specific you can match your favorite balanced feel racquet/bat/etc./your well balanced massive implement of choice and then you have replicated extra copies of your favorite each being the exact same proportional feel and exact same mass quantities.
Ref. Drawing FIG. 1 16th Pg.: A Reference; swing-able proportion massive object/element-01 is 1st mounted into the left distal grip-03 end into stop member-15 of beam-05 in direct opposition to a similar object the tested 2nd mass element-02 that is then equally mounted at opposed side into the right distal grip-04 end to other side stop member-15 of said common mount pivot-able beam-05 that having a center pivot axle-06 located central between said grips 03&04 then both tested massive elements-01&02 are poised in opposition each on a distal side grip-03&04 of beam-05 then each tested mass-01&02 imposes an individual gravity motive-11 each is a counteracting force on the pivot-able beam-05 so that if any differential of counter forces is residual after all equal but opposed forces have canceled each other out any such residual force will cause some degree of beam-05 rotation then attached pointer-07 indicates rotation-12 measured as inequality of mass-01&02 and then indicated on scale-08 as +− out off center thus indicating some mass adjustments need to be made to 2nd tested object-02 if a match is to be had with the ref. 1st object-01. [per our plan] Further; in above If the tested 2nd mass element-02 had been of equal massive proportion as ref. 1st mass Element-01 then No differential forces would exist after both equal massive objects-01&02 gravity motive forces each canceled out the other against pivot-able beam-05 that then has no angular rotation so that scale-08 will read as on center indicating that both tested elements-01&02 have an equal massive proportion same total mass and identical swing mass.
Plan Matching Adjustments:
Prior to doing any measurement on BOC you need to measure both your test racquet's for total weight and balance then you may need to adjust 2nd racquet's balance to be closer to the same as your ref. 1st favorite racquet but still keeping total wt. of 2nd racquet a fraction oz. less than favorite ref. 1St racq. so that some fractional oz. metal wt. strips can latter be added to the frame of unmatched 2nd racquet during final mass proportions adjustment.
Then using your total weight measurement figures that you recorded for both test racquets per accurate digital measure. You calculate weight difference between your 2 test racquets Then this calculated difference weight amount will be added to the lighter 2nd racquet in the form of metal strips placed on along frames moment. Placement will be trial & error until pointer moves toward and finally reads on center scale.
Adjust mounting base to level scale pointer should read exact on center.
By drw. ref. Pointer-07 moving past Scale-08 will indicate degrees +− off center scale of any mismatch between tested elements-01&02 this guides the user by pointer deflections toward a solution for the mismatch.
The match adjustments are made by placement of small mass strips in trial areas-13 along element-02 moment of frame until pointer-07 moves toward a final reading of on center of scale-08. Then all mass proportions of Elements-01&02 are matched. As said the amount of mass required for matching in above plan will be the difference weight E01-E02=Dw you calculated based on your prior recorded total weights measured on each element-01&02.
