[002] This application claims the benefit of provisional application number 60/836,249, filed August 7, 2006, the disclosure of which is hereby incorporated by reference herein, [003] BACKGROUND OF THE INVENTION

[004] Field o£ the invention

[005] This invention relates to exercising and training machines. More particularly, this invention relates to exercising and training machines allowing a user to concentrically exercise a portion of his body through a first path of motion against a resistance and to forcibly eccentrically exercise the portion of his body in an opposite path of motion. [006] P_.e_.scT;_.ig;t_.ion_...of_.....the_....Background_...Art

[007] Presently there exists many types of exercising and training machines designed to exercise portions of a person's body. The most predominant type of exercising and training machine utilizes weight resistance which, through repetition, builds the person's muscles, In our prior invention disclosed in U.S. Patent 5,050,871, the disclosure of which is hereby incorporated by reference herein, we presented an exercise and training machine that exercises a person's ability to accelerate a portion of his body through a path of motion, such as what occurs during the swinging of a baseball bat or a golf club. Our prior exercising and training machine isolated individual muscle groups and measured acceleration of a portion of a person's body. Our prior invention overcame the hesitancy of many professional athletes such as golfers and baseball players who would refrain from resistance weight training during season in fear of adversely affecting their flexibility and ability to swing their golf club or baseball bat in a controlled manner. [008] For the purpose of summarizing our prior invention, the invention comprised an energy absorbing exercising and. training machine for concentrically exercising a person's ability to accelerate a portion of his body through a path of motion. The machine comprised a flywheel rotatably connected to a frame by means of a pair of journal bearings. A harness assembly was provided for connection to the portion of the person's body to be concentrically exercised. Means were provided for interconnecting the flywheel and the harness assembly allowing the flywheel to rigidly engage relative to the harness assembly upon acceleration of the harness assembly relative to the flywheel in a first direction along the path of motion of the body portion being concentrically exercised. The interconnecting means also allowed the flywheel to disengage and freely rotate relative to the harness assembly upon deceleration of the harness assembly relative to the flywheel .

[009] By using our prior invention, the body portion being concentrically exercised in the first direction along the path of motion against the inertial resistance of the flywheel. Upon deceleration of the body portion, the flywheel disengaged relative to the harness assembly to thereby preclude the inertia of the flywheel from exerting a force on the body portion along the path of motion. In the preferred embodiment, the interconnecting means comprised an over-running clutch having an inner x^~ace mounted to a shaft which was connected to the flywheel and journalect in the pair of bearings and having an outer race connected relative to the harness assembly, [00103 The exercising and training machine of our prior invention could be utilised in conditioning and training for many sports and other activities that encouraged the rapid acceleration of a portion of the person's body during concentric exercising, such as what occurred in baseball, golf, and other swing-type activities. The machine was also usable in concentrically exercising individual muscle groups that, were customarily exercised through concentric weight lifting exercises like bench presses, foicep curls and overhead presses. The exercising and training machine was most often utilized in conditioning for golf by concentrically exercising the twisting acceleration of the golfer's torso and legs during a golf swing. [0011] Specifically, when utilised as a torso and legs exercising machine for golfers, the exercising and training machine comprised a stand which adjustably positioned the flywheel, shaft, and overrunning clutch in a position above the golfer's head, with the harness assembly connected to the lowermost end of the shaft by means of a universal joint, preferably a constant velocity universal joint. The harness assembly comprised an inverted substantially U-shaped or V- shaped rigid configuration for fitting over the shoulders and upper torso of the golfer's body. The universal joint allowed the torso harness assembly to universally pivot during the golf swing, [0012] Preferably, the frame comprised a carriaged frame that was operatively connected to the stand by means of slide bearings which allowed the frame., flywheel, shaft and torso harness assembly to freely reciprocate sideways above the golfer's head, the sideways movement being geared to the rotation of the torso harness of the shaft. Furthermore, the shaft was slidably journaled within the pair of journal bearings and the inner race of the over-running clutch to allow the shaft to easily reciprocate vertically. The sideways movement of the carriaged frame, the vertical movement of the shaft, and the pivoting of the torso harness assembly via the universal joint allowed the golfer to concentrically exercise and be trained in a recommended golf swing which requires canting and vertical and sideways movement of the golfer's torso during the backswing and through the golf swing.

[00133 During the golf swing, the golfer's torso concentrically accelerated to his fullest ability and the energy created thereby forced the flywheel into accelerating rotational movement and such energy was absorbed. When the golfer's torso began to decelerate at the end of the golf swing, the overrunning clutch disengaged the shaft allowing the flywheel to freely rotate. Thus, the inertia of the rotating flywheel did not exert a force on the golfer's torso once the golfer's torso began to decelerate or stop. Over-twisting and possible physical damage was therefore precluded, [0014] When the exercising and training machine of our prior invention was adapted to be utilised as a golf and general exercising and training machine, it additionally included means fox" providing an eccentric force to the golfer's torso dui'ing the backswing and partial extension of the torso at the end of the baekswing immediately prior to beginning the golf swing. More particularly, such means may comprise a cammed clutch for interconnecting the flywheel and the shaft . The cammed clutch allowed the flywheel to rigidly engage the shaft only during a predefined arc of rotation. Thus, during the predefined arc of rotation, the flywheel was rigidly connected relative to the harness and provided a momentary inertial eccentric force to the golfer's torso during the end of the backswing. Toward the end of the backswing, the inertia! force of the flywheel provided a momentary slight extension of the golfer's upper torso while the golfer exerted energy by twisting his lower torso in the opposite direction corresponding to a golf swing thereby overcoming the inertial force of the flywheel and reversing its direction. [0015] Finally, a transducer was operatively connected to the frame to sense the rotational speed of the flywheel over time, which, information was then fed into a displayed device to inform the golfer of his progressive ability to concentrically accelerate the flywheel. Additional transducers were also operatively connected to the frame to sense the vertical movement of the shaft, the sideways shifting of the frame and the angular position of the torso harness assembly relative to the shaft. All of such information was then supplied to a computer and analysed to determine the quality of the golf swing.

- α - [00163 More particularly, Figs. 1-5 illustrate the exercising and training machine 10 of our prior invention. Referring to Fig. 1, a carriaged frame 12 was reciprocatably mounted within a vertically adjustable stand., generally indicated by numeral 14, A flywheel 16 was rotatably mounted to the carriaged frame 12 by means of a shaft 18. A torso harness assembly 20 was pivotably connected to the lowermost end of the shaft 18 by means of a universal joint 22. The torso harness assembly 20 was configured to fit over a golfer's shoulders and onto his torso as shown in the phantom in Fig. 1. As described below in greater detail, the exercising and training machine 10 exercised and trained the golfer's ability to concentrically accelerate his torso through a twisting path of motion against the inertial resistance of the flywheel in a first direction corresponding to proper golf swing. As also described below in greater detail, the flywheel of the exercising and training machine 10 eccentrically forces his torso in the reverse direction opposite to that of the first direction corresponding to a through-swing, thereby providing a momentary eccentric extension of the golfer's torso at the beginning of the through-swing .

[0017] As shown in Fig, 2, the torso harness assembly 20 comprised a horizontal member 24 having a substantially horizontal bracket 26 welded thereto and inverted, substantially V-shaped arras 28 extending downwardly from opposing ends thereof. The universal joint 22 was rigidly secured to the bracket 26 by means of threaded fasteners or the like. Inwardly extending pad members 30 were rigidly connected to the arms 28. [00183 As shown in Fig, 1, when the inverted V-shaped arms 28 straddled the golfer's head and slid over the golfer's shoulders onto his torso, the horizontal member 24 was positioned sufficiently above the golfer's head so as to not interfere therewith. As thus configured, the golfer's torso was firmly seated within the torso harness assembly 20 and any rotational or other movement of the torso was transferred to the shaft 18 via universal joint 22. Preferably, universal joint 22 comprised a constant velocity universal joint.

[0019] Referring to Figs. 3 and 4, stand 14 comprised a generally rectangular framework having front, rear and left and right side members 32F, 32R, 32LS and 32RS, respectively, rigidly connected together to define a generally rectangular configuration having an opened center 320, A bracket 34 extended from the front 32F and rear 32R frame members for rigid connection to respective cylindrical support guides or collars 36. Each support guide 36 was slideably fitted over an upstanding cylindrical support tube or pipe 38. The tubes 38 were x'igidly secured in their upright position to a ground platform 40 (see Fig . 1 ) .

[00203 The rectangular framework 32 was vertically adjustable along the length of the tubes 38. Specifically, vertical adjustment was provided by means of rotatable lifting rings 42 positioned about the respective tubes 38, each of which included a plurality of off -axis roller bearing 44 which caused the lifting ring 42 to ascend the tube 38 when rotated in one direction and descend the tube 38 when rotated in the other

- / - direction. Thus, the height of the rectangular framework. 32 was easily adjusted by rotation of the lifting ring 42 on each tube 38.

[0021] The carriaged frame 12 comprised a generally rectangular framework 46 oriented vertically and having top and bottom frame members 46T and 46B and front and rear frame members 46F and. 46R rigidly connected together at their respective corners to define a substantially rectangular configuration. The rectangular framework 46 of the carriaged frame was dimensioned to fit. within the opening 320 defined by the rectangular framework 32 of the stand 14.

[00223 The rectangular framework 46 of the carriaged frame 12 was supported by the rectangular framework 32 of the stand 14 by means of a pair of rails 48 which were rigidly secured to left, and side frame members 32LS and 32RS of the framework 32 of the stand 42 to span the central opening 320 thereof. Slide bearings 50 were rigidly connected to the underside of the top frame member 46T of the rectangular framework 46 of the carriaged frame 12 for slideafoie engagement with rails 48, which allowed the carriaged frame 12 to reciprocate sideways within the opening of the rectangular framework 32 of the stand 14. [0023] As shown in Fig. 5, the shaft 18 was rotatably journaled to the carriaged frame 12 by means of a pair of journal bearings 52 connected to the top and bottom frame members 46T and 46B of the rectangular framework 46. Preferably, shaft 18 comprised a spline shaft and the upper journal bearing 42 included a sleeve 52B and a ball spline bearing 54 with keyway 51

-S- which allowed the shaft 18 to reciprocate vertically relative to the journal bearing 52U and rotate. A stop 56 was connected to the upper end of the shaft 14 by means of threaded fastener 58. Spring 60 was positioned between stop 56 and the sleeve 52B for cushioning .

[0024] Preferably, the sideways movement of the carriaged frame 12 was geared to the rotation of the shaft 18 by means of a cable 53 which was wrapped once around the sleeve 52B and the trailing ends 55 of the cable 53 were rigidly connected to the left and right, side members 32LS and 32RS of the rectangular framework 32. Thus, rotation of the harness assembly 20, shaft 18 and sleeve 52B caused the carriaged frame 12 to travel sideways along the length of the cable 53. Preferably, the cable 53 was wrapped about the sleeve 52B in such a manner that the carriaged frame 12 was in its fully rightward position when the harness assembly 20 is rotated to a position corresponding to the start of the golfer's swing. Thus, as the golfer took his golf swing, the carriaged frame 12 was forcibly moved leftward in synchronism to the rotation of the golfer's torso, thereby training the golfer to exercise a proper golf swing.

[00253 The flywheel 16 comprised a generally disk- shaped configuration (see Fig. 3) . A plurality of upstanding pins 62 were positioned equidistantly about an outer periphery of the flywheel 16 for receiving removable weights €4 to attain a flywheel having a desired mass.

[0026] The flywheel 16 was rigidly connected to the upper protruding portion of the lower sleeve bushing 52LB by means of welding 6B or the like. The flywheel 16 was operatively connected to the shaft 18 by means of an over- running clutch 68 having an outer raceway 680 rigidly connected at a lower surface to the flywheel 16 by means of threaded fasteners 70. A ball spline bearing 72 was positioned within the inner raceway 681 of the clutch 68 and was keyed thereto by means of keyway 74 , Ball spline bearing 72 allowed vertical movement of the shaft 18 therethrough while nonrotatably securing the inner raceway 681 to the shaft. 18, A shim bushing 76 was interposed between the inner raceway 681 and the spline bearing 72.

[00273 Rotation of shaft 18 in one direction caused the inner raceway 681 to rigidly engage the outer raceway 680 of the clutch 68 thereby rigidly interconnecting the flywheel 16 to the shaft 18, thereby providing an inertial resistance. Deceleration of the shaft. 18 relative to the flywheel 16 caused the raceway 680 and 681 to disengage allowing the flywheel 16 to freely over-run without exerting any torque on the shaft 18. Thus, with the torso harness assembly 20 connected to the end of the shaft 18, the golfer's twisting of his torso during the golf swing forcibly accelerated the flywheel 16 against the inertial resistance of the flywheel 16 and, at the end of the golf swing when the torso began to decelerate, the flywheel 16 freely overran to prevent- any force being imparted to the torso harness assembly 20 which would, have otherwise adversely affected the golf swing and possibly cause physical damage to the golfer. [0028] The exercising and training machine 10 of our prior invention further included a cammed clutch, generally indicated by numeral 78 , which interconnected the flywheel 16 and the shaft 18 and allowed the flywheel 16 to rigidly engage the shaft 18 dui'ing a predefined arc of rotation of the shaft in a reverse direction corresponding to the golfer's backswing opposite to the first direction corresponding to the golfer's golf swing. With the clutch 78 engaged, the initial force of the rotating flwheel 16 imparted a momentary eccentric force to the golfer's torso at the beginning of the through swing. Once the disc's rotation was reversed the user is exercising his muscles concentrically. [0029] More particularly, the cammed clutch 78 comprised a first clutch plate 80 which was rigidly connected to the upper sleeve bushing 52LB of the upper journal bearing 52, The cammed clutch 78 further comprised a second clutch plate 82 positioned in alignment with the first clutch plate 80 and rigidly connected to the upper surface of the outer raceway 680 of the over-running clutch 68 by means of threaded fastener 84. A wearable clutch 86 was positioned between the clutch plates 80 and 82. An arcuate cam 88 was rigidly connected to the upper surface of the first- clutch plate 80 and includes end ramp 88R. A corresponding cam roller 90 was rotatably connected to a bracket 92 depending from the top frame member 46T of the rectangular framework 46 in alignment with cam 88. A lower cam roller 94 was rotatably connected to bracket 92 for support to the underside of the second clutch plate 82.

[0030] The cam 88 was arcuately shaped to be engaged by the cant roller 90 along the predefined arc of rotation which corresponded to the backswing of the golfer when the golfer was facing forwardly. Thus, as the golfer began his faackswing, cam roller 90 engaged cam 88 to frictionally engage the clutch plates 80 and 82 together and rigidly interconnect the flywheel 16 to the shaft 18 via sleeve 52B and ball spline bearing 54, After the golfer exerted enough backswing force to rotate flywheel 16, the flywheel 16 would continue on to impart a momentary eccentric force to the golfer's torso as the golfer rotated is lower body in the through swing direction, when the cam roller 90 rolled off ramp 88R of cam 88, the plates 80 and 82 would disengage and allow flywheel 16 to freely rotate, thereby terminating the imparting of the eccentric force. The relative positioning of ramp 88R of cam 88 determined when the flywheel 68 was disengaged such that a certain amount of eccentric extension of the golfer's torso was achieved by proper positioning of the cam ramp 88R relative to the golfer's backswing.

[0031] The inertia created by the rotating flywheel 16 of our prior exercising and training machine 10 functioned to absorb all of the energy of the rotating golfer's swing. However, our prior exercising and training machine 10 lacked any ability to exert control over the inertial resistance of the flywheel 16, other than to disengage the clutch 68 at the end of the golf swing when the torso began to decelerate allowing the flywheel IS to freely overrun and prevent any force being imparted to the torso harness assembly 20.

[0032] Unfortunately, the use of the flywheel 16 in our px~ior exercising and training machine 10 was limited in its flexibility to provide eccentric force during the bacfcswing. Further, the use of the flywheel 16 and the clutch 68 created apprehension in the minds of the user during concentric exercising of the golfer's swing. Further apprehension was created due to the use of the cam roller 90 that terminated the eccentric force of the flywheel during the backswing. Therefore, despite the tremendous functionality of our prior exercising and training machine 10 and the benefits attained during use thereof, there nevertheless existed a need for an improved exercising and training machine that eliminated the use of the flywheel 16.

[0033] Therefore, it is an object of this invention to provide an improvement which overcomes the aforementioned inadequacies of the prior" art devices and provides an improvement which is a significant contribution to the advancement of the exercising and training art .

[0034] Another object of this invention is to provide an exercising and conditioning apparatus and method that imparts a force for eccentric exercising of a user's torso, arm, leg or other" body part to thereby lengthen the duration of eccentric force on the complete range of motion of the applicable muscle group .

[00353 Another object of this invention is to provide an exercising and conditioning apparatus and method that imparts a force for eccentric exercising of a user's torso, arm, leg or other body part through a selectable range of motion appropriate for the condition and flexibility of the user. [0036] Another object of this invention is to provide an exercising and conditioning apparatus and method that imparts a resistance for concentric exercising of a user's torso, arm, leg or other body part through a selectable range of motion. [0037] Another object of this invention is to provide an exercising and conditioning apparatus and method that imparts a fixed or variable resistance or a fixed or variable force for concentric or eccentric exercising of a user's torso, arm, leg or other body part through a fixed or selectable range of motion. [0038] The foregoing has outlined some of the pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or modifying the invention within the scope of the disclosure.

C00393 SUMMARY...0F...THE

INVENTION

[0040] For the purpose of summarizing this invention, our present exercising and training apparatus and method imparts a force for eccentric exercising of a user's torso, arm, leg or other body part through a selectable range of motion appropriate for the condition and flexibility of the user. The apparatus and method of the invention additionally imparts a resistance for concentric exercising of a user's torso, arm, leg or other body part through a selectable range of motion. The selectable ranges of motion during concentric or eccentric exercising may be the same ranges or different ranges. The amount of the resistance or force applied during the respective ranges of motion may each be fixed or may vary throughout the range of motion. [00413 The apparatus and method of the invention may be implemented using double-acting actuators (or two oppositely mounted single-acting actuators) under computer control. The actuators may comprise electric actuators, pneumatic actuators or hydraulic actuators, or a mixture thereof. In the preferred embodiment, the actuators are computer-controlled to provide a fixed or variable concentric resistance along a fixed or variable path of motion in one direction and to provide a fixed or variable eccentric force along a fixed or variable path of motion in an opposite direction.

[0042] Advantageously, the use of computer-controlled actuators eliminates the use of the rotating flywheel of our prior invention that must be mechanically disengaged at the end of each path of motion. Moreover, the computer-controlled actuators of our present invention may be employed in lieu of dead weights in many types of machines adapted for exercising parts of the user's body, such as fox" example, in a squat machine, in a dead-lift machine, a biceps curl machine. Further, the affects of inertia attendant to rapid lifting or lowering dead weights is eliminated. Finally, the computer-controlled actuators of our present invention provides variable resistance or force with significantly greater control than what may be attained by popular full -range variable resistance cams and converging axis movements employed in popular dead-weight exercising machines.

[0043] In addition to computer control of actuators, our present exercising and training apparatus and method significantly improves our prior exercising machine to be more ergonomie and user friendly as well as easier to be dismantled and. packaged for shipping,

[0044] Our present exercising and training apparatus and method may be used by any user such as an athlete, body-builder or layperson. Indeed, our exercising and training apparatus and method is particularly suitable for elderly users or users undergoing rehabilitation who simply wish to increase the range of motion of a certain body part or improve their balance. Improved rotational strength and rotational awareness through use of the machine should reduce the incidence of falls by the eldex'ly and a reduction in the severity of injury in the event of a fall .

[00453 The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows ntay be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiment disclosed may be readily utilised as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims .

[0064] DMAILED_...DESCRIPT_.IM_...O£_..THE_....PREFEMIP_....IMBODIMENT_.S [00653 The preferred embodiments of the exercising and training apparatus and method 110 of the invention described below employ pneumatic actuators. However, it shall be understood that without departing from the spirit and scope of the present invention, other types of actuators may be employed in lieu of pneumatic actuators. The three preferred embodiments of the exercising and training apparatus and method 110 comprise a core-exercising embodiment HOC, a vertical -lift embodiment HOV and an multi-function (leg extension, arm curl, lat pull- down, chest press and butterfly) embodiment HOM, However, it shall be understood that without departing from the spirit and scope of the present invention, other types of equipment may be employed to exercise other parts of a user's body. [00S6] The preferred embodiments of the exercising and training method 110 of the invention employs computer controlled pneumatics for each apparatus embodiment 110 to control fixed or variable resistance (s) along the path of motion in one direction during concentric exercising and to control fixed or variable force (s) during return movement in the opposite direction during eccentric exercising (as used herein in describing concentric and eccentric exercising, the term "resistance" implies concentric exercising whereas the term "force" implies eccentric exercising}. The desired range (s) of motion (i.e., the stroke distances) and the desired fixed or variable resistance is) and force (s) may each be selected by the user through graphical user interface screens HOS under computerized control HOC. [0067] More particularly, as shown in Fig. 6A, the amount of resistance and the amount of force and their stroke distances may be the same, As shown in Pig. 6B, the amount of force may be proportionally greater than the amount of resistance over the same stroke distance (1 1/2:1 illustrated) . As shown in Fig. SC, the amount of force and the amount of resistance may vary in the same proportion over the same stroke distance. As shown in Fig. 6D, the amount of force and the amount of resistance may vary in different proportions over the same stroke distance, As shown in Fig. 6E_; the amount of force and the amount of resistance may vary in different proportions over different stroke distances. Each of such parameters are preferably selectable by the user, [00S8] Core-Exerc.is.ing...Embodiment.

[00693 Referring to Fig, 7, the core-exercising embodiment HOC of the exercising machine of our present invention 110 comprises an ergonomic structure having a base platform 112 with a front deck area 114 on which the user is intended to position himself for exercising. An exercise pad 115 is preferably positioned onto the front deck area 114.

[0070] The rear portion 116 of the platform 112 supports upstanding side supports 118 in an inverted L-shaped configuration which are curved forwardly at their top portion 120 to extend over at least a portion of the deck 114 of the platform 112.

[0071] The lower portion of the supports 118 comprise front, rear and side gusset panels 122 which define a lower compartment 124 in which are positioned various pneumatic components as more particularly described hereinafter. An upper compartment 126 is supported by the top portion 120 of the supports 118, As more particularly described hereinafter, the upper compartment 126 contains various mechanical components from which the harness assembly 132 is operatively suspended by a drive shaft 162. Px~eferably, the supports 118 are hollow to define raceways for pneumatic lines and electrical control cables to extend to and from the lower compartment 124 to the upper compartment 126. [0072] A computer monitor bracket 128 is connected to one of the supports 118 for supporting a touch screen computer monitor 130 at a convenient level for operation by the user while standing on the deck 114 of the platform 112, [0073] As shown in Fig, 8, one embodiment of an improved harness assembly 132 of our new invention comprises an adjustable assembly to accommodate users with larger or smaller torsos. More specifically, the top ends of the rear inverted U-shaped frames 132R each include an angularly-adjustable ratchet, assembly 133 operativeIy connected to a horizontal cross member 132H. The ratchet assembly 133 allows the user to selectively ratchet - adjust the angular separation of the front and rear inverted IT- shaped frames 132F and 132R of the harness assembly 132, Increasing the angular separation accommodates larger-torso users whereas decreasing the angular separation accommodates smaller- torso users,

[0074] As shown in Fig, SC, the ratchet assembly 133 comprises a first gear 133G-1 fixed relative to the horizontal cross member 132H to which is engaged a second gear 133G-2 fixed relative to the frame 132R. The gears 133G-1&2 are urged into engagement by a spring 133S. A pivot lever 133L is operatively connected to the end of the horizontal cross member 132H to relieve, upon pivoting, the force of the spring 133S thereby allowing the gears 133G-1&2 to be disengaged and angularly adjusted. Return pivoting of the spring lever 133L re-engages the geax~s 133G-1&2 to lock their relative angular movement, As shown in Fig. SE, a rotary knob 133K may be employed in lieu of the pivot lever 133L. As also shown in Fig. 8E, the quick-disconnect connection 170 {described below) for the drive shaft 162 may be mounted to a slide 135S to allow side-to-side movement of the drive shaft 162 relative to the harness assembly 132,

[00753 The improved harness assembly 132 comprises improved shoulder pad assemblies 134 each composed of a generally- triangular rigid member 136 positioned at the ends of front and rear inverted U-shaped frames 132F&R of the harness assembly 132. Each of the assemblies 134 comprise a generally triangular rigid member 136 including an angled upper surface 138, a flat vertical inward surface 140 and, in the case of the rear frame 132R, upwardly angled bottom edges 142. Connected to each of the triangular rigid member 136 is a pad assembly 134 comprising a pad 144 preferably composed of a foam covered by a resilient material 146 such as silicone rubber selected to be textured so as to fit against the user's torso and keep the harness assembly 132 from riding up. Each of the pads 144 may be removably fastened to their respective triangular rigid members 136 by a removable fastener such as a hook and loop fastener. The removability of the pads 144 allows the pads to be easily removed to allow positioning side to side to fit. any torso width and for cleaning and replacement once worn.

[00763 Notably, the core-exercising embodiment HOC shown in Fig. 7 is disassemable for shipping in conventional-sized shipping containers by separating the deck 114 and rear portion 116 of the platform 112, separating the upstanding supports 118 at a lower portion and upper portion thereof, removing the touch screen monitor 130 on which the various graphical user interface screens HOS are displayed, removing the screen's bracket 128, removing the harness assembly 132 and positioning such components in a plurality of shipping containers.

[0077] Referring to Fig, 9, contained within the upper compartment 126 is a resistance/force assembly 148 including a pair of left and right stop assemblies 150L and 150R between which is positioned a reciprocating rack assembly 152, The rack assembly 152 contains a pair of double rod double acting cylinders 154 that, under computer control, provide variable resistance along the path of motion upon rotation of the harness assembly 132.

[00783 More specifically, the rack assembly 152 comprising a rack 158 mounted to a support 160 within the resistance/force assembly 148 is supported such that the teeth of the rack 158 are engaged with the teeth of the splines of the vertical drive shaft 162 connected to the harness assembly 132 such that upon sideways movement of the rack assembly 152, the shaft 162 and hence the harness assembly 132 are caused to rotate,

[0079] The vertical drive shaft 162 slideably extends through. upper and lower bearings 164 of the rack assembly 152 to suspend it therefrom during operation while allowing free vertical movement relative to the rack assembly 152. An encoder 153 is provided for rotational position monitoring and resistaii.ee/force control of the drive shaft 162. Finally, the computer 350 of the computerized, control HOC is supported by the rack assembly 148. [0080] As shown in Fig. 10, the lower end of the vertical drive shaft 162 comprises a constant velocity universal joint 163. The harness assembly 132 is coupled to the CV joint 168 by a quick disconnect fitting 170 formed of two halves, one coupled to the CV joint 168 and the other coupled to the harness assembly 132, which may be quickly disengaged to allow removal of the harness assembly 132 from the end of the drive shaft 162. [0081] It is noted that the user's shoulders support the weight of the harness assembly 132, To provide a counterweight relieving the user's shoulders from having to support the weight of the harness assembly 132 or to increase the weight of the harness assembly 132, a pneumatic cylinder 162C (shown in diagrammaticalIy in Fig, 10} may be operatively connected to the drive shaft 162 and supported by the resistance/force assembly 152 and controlled by the computerized control HOC to exert a lifting force to the vertical drive shaft 162 sufficient to relieve all or some of the weight of the harness assembly 132 on the user's shoulders or to impart an additional downward force onto the harness assembly 132 to make it weight heavier on the user ' s shoulders .

[0082] As shown in Fig. 11, the resistance/force assembly 152 is mounted on opposing front, and rear rails 172F and 172R by a pair of linear bearings 174 rigidly connected to the respective corners of the generally rectangular resistance/force assembly 152. A pair of double-acting cylinders 176 are positioned on opposing sides of the bearing 164 to cause side-to-side movement. of the resistance/force assembly 152 along the rails 172. It is noted that preferably a pair of double-acting cylinders 176 are used in lieu of simply one cylinder to assure that there is more uniform movement along the rails 172. As more particularly described below in the fluid diagram of Pig. 13, the paired cylinders 176 are fluidly connected in parallel by conduits to act in unison,

[00833 Referring to Fig, 12, each stop assembly 150 comprises a stop block 178 supported by frame member 180, A screw jack 182 is mounted over an opening in the stop block 178 to allow its center pusher shaft 184 to extend therethrough. A stepper motor 186 is mounted to the stop block 178 having its output shaft aligned, with and coupled, via a coupler, to the drive shaft of the screw jack 182 such that upon rotational movement of the drive shaft of the stepper motor 186, the pusher shaft 184 of the screw jack 182 is caused to move outwardly or inwardly (a spacer" 188 may be provided to assure proper alignment) . The end of the pusher shaft 184 comprise a flange 190 to which is mounted an elongated stop 192. The elongated stop 194 rides above the stop block 178 to preclude rotational movement of the pusher shaft 184 during extension or contraction by the screw jack 182. A bumper assembly 196 may be mounted to the flange 190 to provide cushioning. Under computer control, the stepper motor 186 extends or retracts the pusher shaft 184 outwardly or inwardly to limit the length of travel of resistance/force assembly 152 along the rails 172 and hence the angular rotation of the harness assembly 132. A sensor may be positioned to sense the actual position of the resistance/force assembly at it contacts its bumper assembly 196 to thereby sense left and right movement of the resistance/force assembly 152. Another sensor may be provided to "zero" the fully retracted bumper assembly 196 to its "home" position during initial start-up or upon reset. A computer-controlled encoder 198A is provided for position monitoring and verification.

[0084] Fig. 13 illustrates the air control assembly 200 that controls the reciprocating operation of the double acting cylinders 176 and hence provide angular resistance/force to the harness assembly 132, The air control assembly 200 comprises at least one air compressor 202 (preferably two) that supplies compressed air to a at least one air tank 204 (preferably two to accommodate condensation as described hereinafter) , the output of the second tank 204 being controlled by a PSI switch 206, The air from the tanks 204 is filtered at 208 and controlled on/off at 209 and then provided to a slow start valve 210 to minimize air hammering. The on/off valve 209 may include a quick dump valve to allow immediate dumping of air pressure to atmosphere. [0085] A servo regulator 214 and directional control valve 216 serve to control the direction of air flow into the double acting cylinders 176. Preferably, the servo regulator 214 comprises a proportional pressure regulator, model MPPES, and the proportional directional control valve 216, model MPYE, both sold under the trademark "Festo".

[0086] A timed electric quick dump valve 218 allows purging of condensate from the first tanks 204. The purged condensate is piped to a spray head 220 mounted on a bracket 222 positioned within a electrically- resistance heated drip pan 224 (see Fig. 14 described below) . Inlet and exhaust fans 226 draw airflow over the pan 224 at a rate sufficient to evaporate the condensate. It is noted that a deflector panel may be aligned with the spray head 220 to block any overspray and, doubly serving as a heat radiator itself, serves to increase the evaporation rate. [0087] As shown in Pigs, 15C and 15D₁, a counter balance regulator 162CR may be provided for controlling the counter balance cylinder 162C described above in relation to Fig. 10. [00883 As shown in Fig, 14, most of the components of the air control assembly 200, in particular the compressors 202, air tanks 204 and the quick dump valve 218/drip pan 224 are preferably mounted onto a removable base 230 and positioned within the lower compartment 124. The removability of the base 230 allows it to be removed, via quick disconnect fittings, when the exercising machine 110 is installed within a facility that already has a compressed air supply, As noted above, the air^¬ lines to the cylinders 176 may run in the upstanding supports 118 acting as raceways .

[00893 Returning to Fig. 7, the exercise pad 115 preferably cotnpx'ises closed cell foam that enhances range of motion to exercise the toe muscles and connective tissues concentrically and eccentrically, in plantar flexion and dorsiflexcion. In addition, by virtue of lower leg rotation, the foam pad 115 allows the foot it deflect from the horizontal line of a fixed base which results in a broader range of ankle motion through ankle inversion (turning the sole of the foot inward) and eversion {turning the foot outward) as the lower leg rotates about the ankle joint. As more degrees of eversion take place, there is a pronation of the foot (outer sole turning upward} . By virtue of the resistance at the ankle being introduced from the upper body, the intrinsic muscles and the extrinsic muscles of the feet ax^~e exercised simultaneously. The intrinsic muscles utilized include flexors (plantar flexors) , extensors (dorsiflexors) , abductors, and adductors of the toes. The primary extrinsic muscles of the feet which receive additional recruitment through the use of the foam pad 115 are the gastrocnemius, soleus, tifoiolis posteriar, tibialis anteriar, peroneυs brevis, peroneus longus, flexar hallucis longus, flexar digitorum longus and extensor hallucis longus. The preferred characteristics are reflected in Fig. 15 (Product Code MLC- 2 being the most preferred, AHC the next most preferred and FBC being the next most preferred) .

ISB through 16F. A change mode button 302 allows clearing of the modes. An administrator button 304 displays an administrator screen. [OOS23 The layout of the screens of the respective modes of Figs. 16B through 16F comprises a graduated two- or three-digit resistance column 310 and a graduated single digit resistance column 312 allowing the user to select the desired angular movement for each direction (e.g., select the two (or three) digits 60 then select the single digit 5 for a total of 65 degrees) , which is then angularly displayed in the center circle 314. It is noted that the two columns are employed due to the limited computing power of the microprocessor; however, if a more robust computer is employed, the two columns may be integrated or the circle may be made interactive allowing the angular movement to be "dragged¹ to the desired position. Up and down resistance buttons 316 allows selection of the desired resistance for each direction to be displayed via respective resistance windows 317, Push back force is likewise selected by the up and down force buttons 316 and be displayed via respective force windows 317, A counter window 318 displays the number of repetitions and a total rotation window 319. A stop button 320 resets the counter whereas a start button 322 allows the user to clear the selected angular and resistances and restart from the beginning. A return to home button 324 returns to the main screen 290.
