referring now to the drawings in detail , wherein like numbered elements refer to like elements throughout , fig1 through 4 illustrate a representative structure , generally identified 10 , which is a preferred embodiment of a posture correction tool table that is constructed in accordance with the present invention . generally speaking , the table 10 comprises a plurality of pads that are mounted onto a superstructure . it is this plurality of pads that support the patient during chiropractic treatment . more specifically , and moving from that forward - most point of the table 10 where the patient &# 39 ; s head ( not shown ) would rest , it will be seen that the pads comprise a head pad 40 , a cervical pad 50 , a composite thoracic pad 60 , a lumbar pad 70 , a pelvic pad 80 , a leg pad 90 , and a foot pad 100 . additionally , two semi - circular shaped arm pads 45 are located and mounted to either side of the head pad 40 . this allows the patient , who is supported in the prone position by the table 10 , to rest his or her arms on the arm pads 45 during chiropractic treatment . as shown in fig2 , the table 10 comprises a supporting super - structure generally comprising a bottom frame 20 and a top frame 30 . the bottom frame 20 comprises a plurality of longitudinally - extending bottom frame members 21 and a plurality of integrally - attached , transversely - extending bottom frame members 22 . the transversely - extending bottom frame members 22 each include castor / support subassemblies 23 . the castor / support subassemblies 23 provide for ease of mobility of the table 10 as may be desired or required . the top frame 30 comprises a plurality of vertically - disposed top frame members 31 and plurality of integrally - attached , longitudinally - extending top frame members 32 . a rail 33 is disposed forwardly of the top frame 30 , the purpose of which will be apparent later in this detailed description . the last part of the supporting super - structure of the table 10 of the present invention is the head pad frame 44 . the head pad 40 is a structure comprised of opposing outer pad portions 40 a defining a central groove 40 b . see fig3 . the head pad 40 is secured to a head pad plate 41 which is in turn attached to a top drop plate 43 by means of a plurality of cervical drop links 42 . again , see fig2 . a plurality of dome - shaped bumpers 48 are attached to the top drop plate 43 for cushioning . see also fig7 . the top drop plate 43 is attached to a portion of the head pad frame 44 . attached to the top drop plate 43 is the head and cervical drop sub - assembly 140 . refer again to fig2 . the head pad 40 is raised and lowered electrically . while the table 10 remains horizontal , the head pad 40 in the preferred embodiment and its related structures can be lowered three inches ( 3 ″) below the thoracic pad 60 or raised eight inches ( 8 ″) above the thoracic pad 60 . see fig5 and 7 , for example . this range of movement is accomplished by means of a carriage 34 that is attached to the head pad frame 44 and which is slidably and vertically movable along the rail 33 . this is accomplished by actuation of the ball drive 35 and ball screw 36 . referring now to fig9 , 10 a , 10 b , 11 a and 11 b , it will be seen that the head and cervical drop subassembly 140 comprises a drop pin 141 , a lever bottom stop 142 , a tension tube 143 and a tension knob 144 . to manually “ cock ” the head pad 40 and its related structure , the practitioner pulls upwardly on one end 146 of the cocking bar or lever 145 . it is to be understood that the table 10 of the present invention can be configured such that the head pad 40 can be favored to drop cephalad ( towards the forward portion of the table 10 ) or caudad ( towards the rearward portion of the table 10 ), depending upon the treatment that is desired or required . as is illustrated in much greater detail in fig1 a and 11a , it will be seen that the tension tube 143 houses a tensioning spring 147 that biases a release member 148 against the drop pin 141 . specifically , the drop pin 141 comprises a cylindrically - shaped and dome - topped upper portion 151 and a circumferential and outwardly tapered bottom portion 152 , the bottom portion 152 terminating in a circumferential ridge 153 and capture groove 154 . as the practitioner raises the end 146 of the cocking bar or lever 145 , as shown in fig1 a , the drop pin 141 is elevated by means of a plate that engages a collar portion 155 of the drop pin 141 . in this motion , the upper portion 151 of the drop pin 141 urges the head pad plate 41 upwardly to the pre - drop position shown . in this position , the release member 148 housed within the tension tube 143 is “ captured ” within the groove 154 of the drop pin 141 . this position is maintained until a downward force is exerted on the head pad 40 thereby urging the drop pin 141 downwardly and causing the release member 148 to be pushed into the tension tube 143 and out of the groove 154 of the drop pin 141 . at this point , it should be mentioned that the tension knob 144 covers the full spectrum of tension in just two and a quarter turns . on the lowest tension setting , the weight of the head pad 40 and its plate 41 is enough to cause the head pad 40 to drop . at its highest tension setting , the head pad 40 requires a high amount of force to get the section to drop . it does not require much rotation of the sensitive tension knob 144 to create a great change in tension setting . this functionality is also present in other portions of the table 10 , 12 will be apparent later in this detailed description , like tension knobs being bilateral , however . referring now to fig8 , for example , it will be seen that the head pad 40 can also be moved upwardly or downwardly to allow for flexion and extension of the head pad 40 relative to the horizontal . in the table 10 of the present invention , the head pad 40 can be moved into an unprecedented thirty degrees )( 30 °) in both flexion and extension . this movement is accomplished by use of the release lever 49 disposed to one side of a hydraulic tube or cylinder 46 , which use extends or retracts the rod 47 within the tube 46 . see fig8 a . more specifically , when the lever 49 is depressed upwardly , it releases the rod 47 of the gas cylinder 46 to quietly and smoothly raise , lower or angle and lock the head pad 40 . this functionality is present in other portions of the table 10 as well , as will be apparent later in this detailed description . the table 10 of the present invention also comprises a cervical instrument adjusting fulcrum in the form of a cervical pad 50 , the cervical pad 50 being supported by and rotatably mounted about a vertically - adjustable structure 52 . see fig1 and 13 . the cervical instrument adjusting fulcrum that is utilized in the table 10 of the present invention is unique . to the knowledge of this inventor , no other table of past or current manufacture includes this structure . use of this structure allows the chiropractor the ability to create the exact patient posture that is necessary in order to utilize impulse adjusting instruments to correct postural positioning of the patient . one such instrument is disclosed and claimed in u . s . pat . no . 7 , 144 , 417 issued to colloca et al . during usage of such an instrument with the adjusting fulcrum and cervical pad 50 , the patient is positioned on his or her side with the patient &# 39 ; s neck being properly positioned for instrumental stimulation . prior to this innovation , chiropractors would resort to supporting the patient &# 39 ; s neck with pillows , wedges or some combination of both . use of the adjustable cervical pad 50 is novel and unprecedented . referring again to fig1 through 4 , it will be seen that the thoracic pad 60 is comprised of opposing outer pad portions 60 a and a central pad portion 60 b . the next adjacent pad is the lumbar pad 70 . see also fig1 . referring specifically to fig1 , 16 and 17 , it will be seen that the thoracic pad 60 is attached to a thoracic pad plate 61 and that the lumbar pad 70 is attached to a lumbar pad plate 71 . the thoracic pad plate 61 and the lumbar pad plate 71 are each attached to a single “ common ” thoracic - lumbar support plate 62 . the common thoracic - lumbar support plate 62 is hingedly attached to a portion of the top frame 30 by means of a primary hinge 65 . a secondary hinge 63 is also provided to allow the thoracic pad plate 61 and the lumbar pad plate 71 to each rotate upwardly from the common thoracic - lumbar support plate 62 at the secondary hinge 63 . see fig1 . as shown in fig1 , the common thoracic - lumbar support is plate 62 is rotatable about the primary hinge 65 . elevation of the common thoracic - lumbar support plate 62 is accomplished by actuation of the hydraulic tube 66 via the bilateral lever 67 . the functionality of this hydraulic tube 66 is essentially identical to that of the hydraulic tube 46 that is used with the head pad 40 and its related structure . the hydraulic tube 67 that is attached to the common thoracic - lumbar support plate 62 allows the plate 62 to be raised up to fifty - five degrees )( 55 °) above the horizontal . a plurality of bumpers 68 are disposed between the common thoracic - lumbar plate 62 and the top frame 30 to cushion the return of the plate 62 to the horizontal . referring again to fig1 , it will be seen that the common thoracic - lumbar plate 62 has a plurality of apertures 64 defined in it . the purpose of the apertures 64 is to allow for access to the thoracic pad plate 61 and to the lumbar pad plate 71 from below . situated below each of these plates 61 , 71 is a thoracic drop subassembly 160 and a lumbar drop subassembly 170 , respectively . referring again to fig1 , it will be seen that the thoracic drop subassembly 160 comprises a drop pin 161 , a lever bottom stop 162 , a tension tube 163 , a pair of bilateral tension knobs 144 ( see fig1 ) and a miter gear assembly 169 . to manually “ cock ” the thoracic pad 60 and its related structure , the practitioner pulls upwardly on one end 166 of the bilateral cocking bar or lever 165 . see also fig1 . it will also be seen that the tension tube 163 houses a tensioning spring 167 that biases a release member 168 against that drop pin 161 . the drop pin 161 comprises a cylindrically - shaped and dome - topped upper portion 181 and a circumferential and outwardly tapered bottom portion 182 , the bottom portion 182 terminating in a circumferential ridge 183 and capture groove 184 . as the practitioner raises the end 166 of the bilateral cocking bar or lever 165 , the drop pin 161 is elevated by means of a plate that engages a collar portion 185 of the drop pin 161 . in this motion , the upper portion 181 of the drop pin 161 urges the thoracic pad plate 61 upwardly to the pre - drop position shown in phantom view in fig1 . in this position , the release member 168 housed within the tension tube 163 is captured within the groove 184 of the drop pin 161 . as is also shown in fig1 , the table 10 of the present invention further comprises a lumbar drop sub - assembly 170 . the lumbar drop sub - assembly 170 comprises a drop pin 171 , a lever bottom stop 172 , a tension tube 173 , a pair of bilateral tension knobs 174 ( see fig1 ) and a miter gear assembly 179 . to manually “ cock ” the lumbar pad 70 and its related structure , the practitioner pulls upwardly on one end 176 of the cocking bar or lever 175 . it will also be seen that the tension tube 173 houses a tensioning spring 177 that biases a release member 178 against the drop pin 171 . this drop pin 171 again comprises a cylindrically - shaped and dome - topped upper portion 191 and a circumferential and outwardly tapered bottom portion 192 , the bottom portion 192 terminating in a circumferential ridge 193 and capture groove 194 . as the practitioner raises the end 176 of the cocking bar or lever 175 , the drop pin 171 is elevated by means of a plate that engages a collar portion 195 of the drop pin 171 . in this motion , the upper portion 191 of the drop pin 171 urges the lumbar pad plate 71 upwardly to the pre - drop position shown in phantom view in fig1 . in this position , the release member 178 housed within the tension tube 173 is captured within the groove 194 of the drop pin 171 . it should again be mentioned here that the tension knobs 164 , 174 illustrated in fig1 cover the full spectrum of tension in just two and a quarter turns . on the lowest tension setting , the weight of the respective pads 60 , 70 and their plates 61 , 71 is enough to cause the pads 60 , 70 to drop . at their highest tension setting , the pads 60 , 70 require a high amount of force to effect a drop . it does not require much rotation of the sensitive tension knobs 164 , 174 to create a great change in tension setting . the table 10 of the present invention further comprises a pelvic pad 80 . see fig3 , 4 and 19 through 21 in this regard . as shown , the pelvic pad 80 is supported by and attached to a pelvic pad plate 81 . the pelvic pad plate 81 is attached to a drop bracket 82 . disposed vertically below the drop bracket 82 is a pelvic column outer - housing 83 and a pelvic column inner - housing 84 . the inner - housing 84 is slideably moveable within the outer - housing 83 . disposed within the outer and inner - housings 83 , 84 is a hydraulic tube 86 that is actuated by a lever 87 . a plurality of bumpers 88 are mounted to the top frame 30 to provide cushioning for the pelvic pad plate 81 when the pelvic pad plate 81 is dropped or lowered to its bottom - most position . referring now to fig2 through 22 in particular , it will be seen that a pelvic drop sub - assembly 110 is also provided . the pelvic drop sub - assembly 110 comprises a drop pin 111 , a bottom stop 112 , a tension tube 113 , a pair of bilateral tension knobs 114 and a miter gear assembly 119 . as shown , the tension tube 113 houses a tensioning spring 117 that biases a release member 118 against the drop pin 111 . the drop pin 111 comprises a cylindrically - shaped upper portion 121 and a circumferential and outwardly tapered bottom portion 122 , the bottom portion 122 terminating in a circumferential ridge 123 and capture groove 124 . in the preferred embodiment , the cocking bar or lever ( as was used with the other pad elements previously discussed ) is replaced by a foot lever sub - assembly 130 . see fig1 , 23 and 24 . the foot lever sub - assembly 130 is attached to a link 133 which allows the drop pin 111 to be “ cocked ” by the practitioner pushing down on one of two spring - loaded bilateral foot pedals 131 . depression of the foot pedal 131 rotates a linkage 132 that elevates a plate 133 that engages a collar portion 125 of the drop pin 111 . in this motion , the upper portion 121 of the drop pin 111 urges the pelvic pad plate 81 upwardly to the pre - drop position shown in fig2 . in this position , the release member 118 housed within the tension tube 113 is captured within the groove 124 of the drop pin 111 . the drop pin 111 is further attached to a bottom - most shaft 129 by means of a pelvic drop link 89 . the bottom - most shaft 129 is also attached to the lowest portion of the hydraulic tube 86 of the pelvic drop portion of the table 10 . this results in coordinated movement between the drop pin 111 and the pelvic pad 80 . finally , disposed at the rearward - most end of the table 10 of the present invention are the leg pad 90 and the foot pad 100 . see fig3 , 4 , 25 and 26 in particular . as shown , the leg pad 90 is supported by and attached to a leg pad plate 91 . the leg pad plate 91 is attached to the top frame 30 by means of a hinge 92 . the hinge 92 allows the leg pad plate 91 and leg pad 90 to rotate about the top frame 30 . the leg pad plate 91 is variably positionable relative to the horizontal by means of a hydraulic tube 93 and actuation lever 94 of the type previously described . the foot pad 100 is attached to a supported by a foot pad bracket 101 . the foot pad bracket 101 is secured to a longitudinally - extending slide 102 , the slide being longitudinally moveable along a slide receiver 103 . this movement is shown in phantom view in fig2 and 26 . in view of the foregoing , it will be apparent that there has been provided an improved posture correction tool in the form of a chiropractic adjusting table that has certain new , useful and non - obvious features including “ flying drops ” in the thoracic and lumber sections ; pelvic elevation “ flying drop ” in the pelvic section ; a cervical instrument adjusting fulcrum ; a uniquely - movable head piece ; polyurethane pads ; and which is easy to move and eliminates conventional “ pinch points ” for enhanced safety .
