initial reference is given by way of fig .- 1 , wherein is exhibited the believed primary ‘ prior - art ’, my original and still popular mk - i / pow &# 39 ; rpad ® 4 - finger grip - pad 11 . in light of my recent r & amp ; d - studies into the dynamics of baseball - bat percussion upon impact with an official hardball , my mk - i design 11 has been revealed to provide a less than optimal configuration , particularly as it applies to usage by baseball - batters . while indeed providing a degree of protection from so - called ‘ bat - sting ’, as a batter &# 39 ; s aid the construction of my mk - i does not adequately meet the needs of today &# 39 ; s baseball - batters , owing both to the bulk of its excessive full - palm longitudinal - width , and its inability to provide hand protection which can be advantageously varied in compliance resilience according to individual user requirements . note in fig .- 1 how the mk - i &# 39 ; s flexile planar main - body ( a ) is constructed of frothed - neoprene , but clad only on the palm interfacing side with a fine - denier nylon / stretch - fabric ( b ), while the obverse broad - side surface ( c ) is formed shaved of the normal smooth - skin , which notion was to promote a greater as coefficient - of - friction relative to the bat - handle . plus , an elongate wedge - shaped longitudinal - axis ( d ) bolster - cushion ( e ) was permanently bonded to the pad &# 39 ; s exposed - cell surface ( c ), which has proved to be excessively bulky for many batters . moreover , the finger - holes ( f ) tend to fray and tear - out ( especially when used over a batting - glove ) owing to absence of bilateral reinforcement by an opposing layer of nylon / stretch - fabric . accordingly , study of generic figs .- 2 a / 2 b / 3 at once reveals the major change in construction residing in my new mk - ii grip - pad embodiment . for example , it has been discovered that owing the inherent friction of finger - hole impingement upon the forefinger , a minimalist 1 - finger embodiment is now provided per figs .- 2 a / 2 b , owing provision of a fine - denier nylon / stretch - fabric upon both sides of the pad - body 13 ( proximal the finger - base impinging side 13 ′), and at the bat - handle impinging side 13 ″. surprisingly , the design first introduced in my here exemplified mk - ii 2 - finger pow &# 39 ; rpad ® configuration of fig .- 3 , has come to realize its ultimate performance potential via the relative diminutive size of my latest mk - ii 1 - finger pow &# 39 ; rpad ® embodiment exhibited in figs .- 2 a / 2 b ; yet it is this novel generic construction ( shared by both 1 - finger and 2 - finger versions ) which has enabled a significant performance advancement , — which shall be elaborated upon later herein . examining the generic features better revealed in enlarged fig .- 2 b , we note the same basic construction configuration is shared by both the 1 - finger and 2 - finger embodiments , and that the insert - cushion 16 may include an optional hollow center 16 h , which provision is designed to further modulate compliance . the flexile ( ie : pliant and stretchable ) planar grip - pad body 13 is comprised of commercially available 1 / 16 - inch to ¼ - inch ( preferably the thinner gauge of material ) frothed - neoprene which is durably clad upon both broad sides with nylon / stretch - fabric . this unique grip - pad body is first die - cut into an elongated d - shape , while simultaneously punching a forefinger - hole ( plus an optional middle - finger hole immediately thereunder in the case of a 2 - finger configuration ) proximal the upper - corner 14 of the planar body &# 39 ; s outward - terminus . then the o - shaped receiver - sleeve 15 portion is created by folding the inward - terminus 15 ′ once over upon itself to the extent of at least ½ - inch , and 1 - inch at the most , where it is permanently attached via linear machine stitching 15 ″; which constitutes completion of the basic mk - ii grip - pad 1 - finger and 2 - finger construction . finally , we install a generally extruded standard insert - cushion 16 ( short length exemplified in fig .- 2 b ) into the resulting elastic receiver - sleeve 15 , — thereby comprising the essential core of the overall assembled bolster 19 . note also , that the selected insert - cushion 16 may be substantially flush with the top and bottom openings of the receiver - sleeve ( as exemplified in fig .- 2 b ), or it may be preferred that the insert - cushion terminuses extend upwardly 16 ″ or downwardly 16 ″ as is exemplified in fig .- 2 a and fig .- 3 ; or alternately . filling just half of the receiver - sleeve 15 as is indicated at 16 ′ in fig .- 3 ( wherein the insert - cushion may not be extend down in the lower - half of the receiver - sleeve 15 , if an individual batter prefers to emphasize concentration of cushioning at the upper portion of the receiver - sleeve ). the embodiment of fig .- 3 is that of my new standard 2 - finger mk - ii pow &# 39 ; rpad ®, which is essentially a longitudinally elongated version of my fig .- 2 a 1 - finger pow &# 39 ; rpad ®, the primary advantage of this 2 - finger embodiment resides in its providing a self - aligning relationship relative to the base - region 20 b of the two upper fingers ( forefinger and middle ). note also that my mk - ii pow &# 39 ; rpad ® may be made in various different sizes ; hence , proportionately scaled up or down according to the hand dimensions of very young ball - players , as versus the hand of a full - adult pro / ball - player . there remain subtle , however vital other differences which are to become herein more evident and understood as important improvements . for example , fig .- 4 shows how by virtue of finger - hole 14 ′ anchoring of the pad - body 13 to user &# 39 ; s forefinger 21 ′, the bolster 19 portion becomes naturally lodged in position between conventional bat - handle 10 and the base - region 21 b of batter &# 39 ; s upper - hand ; thereby shielding the sensitive web region 21 m spanning between thumb 21 and forefinger 21 ′ ( although normally covered by skin - tissue which is removed here , revealing the underlaying apt / abductor - pollicis - trans muscle ) 21 m from dreaded bat - sting . however , orientation of my 1 - finger version in fig .- 2 a is necessarily reliant upon the friction - fit of the elastic pad material surround alone , while my 2 - finger version in fig .- 3 has the advantage of providing absolute positive orientation ( will not rotate in azimuth about the forefinger ) relative to the apt 20 m . study of fig .- 4 serves to graphically demonstrate how my longitudinally abbreviated 1 - finger mk - ii bolster 19 ′ configuration , and elongate 2 - finger configuration 19 ″, act to advance per ref .-‘ x ’ the swing stroke position of the bat &# 39 ; s longitudinal - axis 10 ′ approximately 1½ - degrees to 3 - degrees ( given a normal hand grip usage , and dependent upon the diameter and compliance resilience of the bolster ). this advantageous function is shown measured as an angle - of - incidence of displacement from the bat &# 39 ; s basic longitudinal - axis 10 ″ poised perpendicularly , at a right - angle relative to the batter &# 39 ; s upper - hand forearm - axis 20 ; and by way of comparison , represents the basic position of the bat &# 39 ; s longitudinal - axis 10 ′ without use of my grip - pad aid , while the longitudinal - axis 10 ″ represents the approximate displacement of the bat &# 39 ; s longitudinal - axis when either of my mk - ii grip - pad &# 39 ; s 12 ′/ 12 ″ are being worn upon batter &# 39 ; s upper - hand 20 ′. hence , it is to be understood that when a batter swings their bat while wearing my mk - ii grip - pad 12 ′/ 12 ″, the pitched - ball 22 actually approaches the batter &# 39 ; s strike - zone 22 ′ ( transverse - line on action ref .- arrow ) above the batting - plate ( not shown ) during an earlier sequence of the batter &# 39 ; s swing , as compared to the same situation without use of my grip - pad . accordingly , in the stage of the batter &# 39 ; s swing wherein they break from the basic poise of their bat , and commences to rotate their wrists at a point approximately above the batting - plate as is exemplified in fig .- 4 , it is herein postulated that the bat has actually traveled slightly further through the hitting - zone than if my device were not employed . moreover , by optimizing this advanced displacement of the bat - handle 10 poised in the batter &# 39 ; s hands , the batter is thereby enabled to swing at an enhanced angle through the hitting - zone 22 ′ ( action ref .- arrow ), thereby serving to improve the batter &# 39 ; s physical leverage , resulting in increased bat - speed , which equates to greater power potential to send a ‘ well hit ball ’ ( ie : on the so called sweet - spot of the bat - barrel ) further , yet with better control , — according to batter testimonials . note also , that this function is in addition to the rebounding - effect discussed earlier in the summary - section hereof . instead of the herein preceding considered ‘ standard ’ closed - celled foam - core type of resilient insert - cushion 16 ( which can be molded / extruded in various compliance durometers ), in fig .- 5 is shown an alternate imperforately sealed somewhat balloon like fluid - medium filled resilient capsule like insert - cushion 18 , having an approximately 1 / 32 - inch to 1 / 16 - inch thickness flexile - polymer wall - structure 17 ′ ( ie : such as of tough urethane - resin material ) forming the internal spatial confine 17 ″, wherein the contained fluid can either be ‘ pneumatic ’ ( by containing a compressive gas such as air , nitrogen , — etc .) or ‘ hydraulic ’ ( a non - compressive liquid such as a saline - solution of water / h 2 o ); either medium usage being according to user preference and engineering - design choice . while the pneumatic embodiment is advantageously lighter - weight and exhibits a substantially greater degree of cushioning compliance than the hydraulic version ( for a given wall - thickness ), the hydraulic version naturally relies upon the inherent elastic quality of the wall - structure 17 ′ when subjected to momentary compressive - loads ; while both of these embodiments can be made to different longitudinal lengths and diameters (— ranging between ⅜ - inch to ¾ - inch ) for selective interchangeable employment as an insert - cushion 17 within the elastic receiver - sleeve 15 of either my fig .- 2 a and fig .- 3 grip - pad embodiments as a substitute for the generally foam - polymer or foam - elastomer insert - cushion indicated as 16 ( or 16 ′/ 16 ″). accordingly the length options of this fluid type insert - cushion capsule 17 are regarded as equivalent to that set forth for the standard insert - cushion ( 16 / 16 ′/ 16 ″). in fig .- 6 is shown a more elaborate variable - compliance iteration of my preceding ultimately simple capsule 17 like insert - cushion , here a hybrid embodiment pump equipped capsule 18 , in which one end of the fig .- 5 capsule is left open , and the flexile wall material 17 ′ is ultra - sonically permanently bonded to the rigid cylinder - wall insert 18 ′, thereby forming a pressure - chamber 18 c ′ which can be readily inflated as desired by the user , even while at bat if desired ! to operate , user removes the standard insert - cushion 16 from the receiver - sleeve 15 of their mk - ii grip - pad 12 ′/ 12 ″, and inserts this special pump capsule 18 , leaving the approximately ½ - inch rigid pumping portion extending either well upward or well below the receiver - sleeve &# 39 ; s terminuses 15 ′ and 15 ″ respectively . the user then can finger depress pushbutton portion 18 ″ several times to attain degree of air - pressure desired within the pressure - chamber 18 c ′. being that the annular pushbutton 18 ″ is preferably injection - molded plastic formed integrally with the piston - body portion 18 # ( having integrally - molded feather - edged flange - seal portion 18 s ), each stroke of the ( ref .- action of large white - arrow , whilst the large black - arrow represents the default return - stroke biasing - action of pushbutton 18 ″) piston - body 18 # forces air passed the rubber flapper - valve 18 v ′ into the pressure - chamber 18 c ′ on other side of bulkhead 18 b , while conical check - valve 18 v ″ necessarily becomes seated ( to maintain air within anti - chamber 18 c ″ for compression purposes ). if the user senses an excessive firmness of the flexile wall 17 ′, the user merely depresses the conical check - valve 18 v ″ briefly with the tip of their fingernail ( while depressing pushbutton 18 #), thus moving the relief - plunger 18 p to open flap - valve 18 v ′ thereby releasing captive air - pressure to the extent desired . in fig .- 7 is shown a human - hand wherein the skin - tissue has been removed to reveal the underlaying tendons and musculature . as has been stated herein , an important function of this invention disclosure is to facilitate improved protection of the web region identified as the apt / abductor - pollicis - trans muscle 21 m , which spans between the batter &# 39 ; s thumb 21 and their forefinger 21 ′. thus , it is readily understood how the preferred and generic - variant embodiments of this invention contemplate performing functions in a novel way not heretofore available nor realized . it is implicit that the utility of the foregoing adaptations of this invention are not necessarily dependent upon any prevailing invention patent ; and , while the present invention has been well described hereinbefore by way of certain illustrated embodiments , it is to be expected that various changes , alterations , rearrangements , and obvious modifications may be resorted to by those skilled in the art to which it relates , without substantially departing from the implied spirit and scope of the instant invention . therefore , the invention has been disclosed herein by way of example , and not as imposed limitation , while the appended claims set out the scope of the invention sought , and are to be construed as broadly as the terminology therein employed permits , reckoning that the invention verily comprehends every use of which it is susceptible . accordingly , the embodiments of the invention in which an exclusive property or proprietary privilege is claimed , are defined as follows .
a baseball batter &# 39 ; s improved grip enhancing pow &# 39 ; rpad ™ device providing therapeutic vibration sting - absorption , which in critically configured for use upon one &# 39 ; s upper / batting - hand , while primarily employing the forefinger but optionally including the adjacent middle - finger for positioning stability . the user &# 39 ; s two fingers are fully inserted through a pair of intimately fitting spaced apart holes provided into a resiliently flexile preferably frothed - neoprene roll - stock material , clad on both sides with reinforcing nylon / stretch - fabric . an integral bolster cushion portion is arranged distally opposite the finger - holes , formed via a circular - wrap of the pad material around an extruded - core of resilient material . this constitutes the primary performance enhancing feature , whereby both ‘ advanced bat positioning ’, and advantageous ‘ rebound - effect ’ is provided ; — enabling the batter to hit a ball further with greater control . the insert - cushion can be selectively changed , thereby offering variable compliance characteristics according to individual user preference ; thus encouraging a more aggressive bat - swing action by dispelling any subconscious trepidation over dreaded debilitating hand - injury shock - trauma .
