Definitions

  • This invention relates to the general technical field of exercise, physical fitness and physical therapy equipment and machines and to the more specific technical field of treadmills that can be operated in a forward and/or rearward walking and running mode to simulate pushing and pulling exercises.
  • This invention also relates to the more specific technical field of using a resistance mechanism to generate a constant static resistance for simulating the pushing and pulling of a load, which resistance can be adjusted (increased and decreased) by the user while exercising.
  • Exercise, physical fitness and physical therapy equipment and machines are available in various configurations and for various purposes, and are available for all of the major muscle groups.
  • Exercise treadmills are well known and are used for various purposes, including for walking or running aerobic-type exercises, and for diagnostic and therapeutic purposes.
  • the person (user) on the exercise treadmill normally can perform an exercise routine at a relatively steady and continuous level of physical activity, such as by maintaining a constant walking or running velocity and a constant incline, or at a variable level of physical exercise, such as by varying either or both the velocity and incline of the treadmill during a single session.
  • Exercise treadmills typically have an endless running surface extending between and around movable rollers or pulleys at each end of the treadmill.
  • the running surface generally is a relatively thin rubber-like material driven by a motor rotating one of the rollers or pulleys.
  • the speed of the motor is adjustable by the user or by a computer program so that the level of exercise can be adjusted to simulate running or walking.
  • the endless running surface typically is supported along its upper length between the rollers or pulleys by one of several well known designs in order to support the weight of the user.
  • the most common approach is to provide a deck or support surface beneath the belt, such as a plastic, wood or metal panel, to provide the required support.
  • a low-friction sheet or laminate such as TEFLON® brand of synthetic resinous fluorine-containing polymers, can be provided on the deck surface (or indeed can be the material of construction of the deck surface) to reduce the friction between the deck surface and the belt.
  • incline is accomplished in one of two manners - either the entire apparatus is inclined or just the walking and running surface is inclined. Further, the inclination can be accomplished by either manual or power driven inclination systems, and can be accomplished either at the command of the user or as part of a computerized exercise regimen programmed into the exercise treadmill.
  • An inclination takes advantage of the fact that the exercise effort, or aerobic effect, can be varied with changes in inclination, requiring more exertion on the part of the user when the inclination is greater.
  • Most known exercise treadmills are structured to allow the user to walk or run in a forward direction, with the belt traveling in a direction that simulates walking or running forward; that is, the belt runs across the top of the deck in a front to back motion.
  • the inclination mechanisms in most exercise treadmills are structured to allow the user to walk or run in a level or uphill inclination; that is, the front of the deck can be level with the back of the deck or can be raised relative to the back of the deck to simulate an uphill inclination.
  • the hand rails and controls in most exercise treadmills are structured to compliment simulated forward motion and are fixedly attached to the treadmill base.
  • a specialty treadmill developed by this inventor and patented under US Patent No. 7,575,537 is structured to allow the user to comfortably simulate a pulling or dragging motion; that is, a backwards walking motion either on a level plane or uphill.
  • This exercise treadmill that provides a constant static weight resistance against pushing so as to simulate pushing of a load, which weight resistance can be varied (increased and decreased) by the user.
  • This simulated pulling or dragging motion can be useful for exercising and developing different groupings of muscles and for providing an aerobic workout.
  • this inventor is unaware of any specific exercise treadmill that is structured to allow the user to comfortably simulate both a load-pushing motion; that is, a forwards walking motion while simulating pushing a load, either on a level plane or uphill, and a load-pulling motion; that is, a rearwards walking motion while simulating pulling a load, either on a level plane or uphill. Additionally, with the exception of this inventor's invention, this inventor is unaware of any specific exercise treadmill that provides a constant static weight resistance to simulate both the pushing and the pulling of a load, which weight resistance can be varied (increased and decreased) by the user during the exercise regimen.
  • a simulated pushing motion can be useful for exercising and developing different groupings of muscles of both the upper and lower body and for providing an aerobic workout.
  • an exercise treadmill simulating both a pushing motion and a pulling motion would be useful, novel and not obvious, and a significant improvement over the prior art. It is to such an exercise treadmill that the current invention is directed.
  • the present invention is a cardiovascular cross training device that addresses many needs not met with the current industry offering of treadmills, elliptical devices, stationary bicycles, and stair climbing devices. Walking and running is incorporated into the fitness and physical rehabilitation programs prescribed by many professional fitness trainers, physical therapists, sports medicine professionals and strength and conditioning professionals. Additionally, many athletes use weight loaded sled pushing and pulling to augment their lower body strength training as well as their overall aerobic and anaerobic conditioning programs. Adding the additional load factor of horizontal resistance (that is, a simulated pushing or pulling motion) and the energy expenditure and muscle loading to the lower body is increased. This increased energy output allows an individual to achieve and maintain their desired heart rate walking or running at a fraction of the speed of any forward walking or running motion oriented exercise that does not incorporate pushing or pulling a load. The present invention combines these features in a versatile cross training device.
  • the present invention is an exercise treadmill for simulating the pushing and pulling of an object on a level surface, up an incline or down a decline.
  • the treadmill has a lower base having the treadmill surface and housing the internal mechanical components of the walking platform, a movable resistance handle, a fixed console support structure on which at least one pushing and pulling means is attached, and a resistance mechanism located proximal to the console support structure.
  • Various control switches and displays for operating the invention can be located on the pushing and pulling means and/or the console support structure.
  • the resistance mechanism can be operatively connected to the pushing and pulling means via a cable.
  • the resistance mechanism can be operatively connected to the pushing and pulling means by levers, rods, or the like.
  • the resistance mechanism can be operatively directly connected to the pushing and pulling means.
  • the pushing and pulling means can be operatively attached to the resistance mechanism via a cable or other linking means that can pass through and can be operatively supported by the side support structures and/or the console support structure.
  • the pushing operation when a user steps onto the treadmill and grips the pushing and pulling means and starts the treadmill belt moving, the user begins to walk or run in a forwards direction relative to the console support structure, causing the user to push on and move the pushing and pulling means in a pushing direction.
  • the treadmill may be set up to begin to move automatically at a speed and at an inclination according to a value entered from the input means located on the pushing and pulling means or on the control console.
  • This pushing transfers from the pushing and pulling means, to the main cable or other connecting linkages and/or cables, which is or are operatively connected to the resistance mechanism, thus acting on the resistance mechanism.
  • the action of the pushing and pulling means on the resistance mechanism can be by many means, such as cables, wires, rods, levers, gears, or the like, directly or indirectly, and structurally attached or in cooperative communication.
  • the treadmill may be set up to begin to move automatically at a speed and at an inclination according to a value entered from the input means located on the pushing and pulling means or on the control console.
  • This pulling transfers from the pushing and pulling means, to the main cable or other connecting linkages and/or cables, which is or are operatively connected to the resistance mechanism, thus acting on the resistance mechanism.
  • the action of the pushing and pulling means on the resistance mechanism can be by many means, such as cables, wires, rods, levers, gears, or the like, directly or indirectly, and structurally attached or in cooperative communication.
  • the resistance mechanism can be set by the user to a specific amount, such as for example 10 kilograms, comparable to known resistance mechanisms such as weight stacks.
  • a specific amount such as for example 10 kilograms
  • known resistance mechanisms such as weight stacks.
  • the counterforce is static and approximately constant at the set weight or level throughout the entire range of movement of the pushing and pulling means, except in some embodiments at the very start of the range of motion when the resistance mechanism is resting on a stop.
  • the resistance mechanism exerts a counterforce on the user of the set weight, 10 kilograms in this example, or level whether the user has pushed or pulled the pushing and pulling means a smaller distance or a larger distance, and this set resistance is static and approximately constant, at 10 kilograms in this example, unless the resistance mechanism is reset to a different amount.
  • the degree of resistance of the resistance mechanism can be controlled by the user to simulate pushing or pulling a weight such that the exercise regimen is similar to walking or running forwards or backwards while pushing or pulling, respectively, an object of a weight comparable to the setting of the resistance mechanism. The higher the setting of the resistance mechanism, the heavier the simulated object being pushed or pulled.
  • the degree of resistance also is adjustable in that the user can set the specific amount of resistance to any amount within the parameters of the resistance mechanism structure prior to and during the exercise regimen, depending on the embodiment of the invention, with slight variations based on the position of the pushing and pulling means.
  • the degree of resistance can be set prior to starting the exercise regimen or during the exercise regimen. Further, the degree of resistance can be changed (increased, decreased, eliminated) by the user during the course of the exercise regimen.
  • the resistance mechanism is a moment arm mechanism comprising a moment arm, an adjustable weight, and a drive mechanism for moving the adjustable weight relative to or along the moment arm.
  • the weight resistance of the moment arm is increased or decreased, thus simulating the pushing of various or varying load weights.
  • the moment arm is operatively connected to the pushing and pulling means via drive cables, thus transferring the weight resistance effect to the user.
  • the moment arm creates a constant and static counterforce equivalent to the specific weight amount set by the user.
  • a single pushing and pulling means such as a movable console slidably mounted on the console structure that is operatively connected to the resistance mechanism, or a single pushing bar that is operatively connected to the resistance mechanism and that connects to either side of the treadmill to form a horizontal bar or handle in front of the user that can be pushed forward or pulled backwards.
  • the pushing and pulling means can be rigidly attached to the console structure and the console structure is movable (pivotable or slidable, for example) such that when the pushing and pulling means is moved, the entire console structure moves to activate the resistance mechanism.
  • the resistance mechanism is a pneumatic mechanism comprising a pneumatic cylinder, an air compressor, and various connecting hoses.
  • the resistance of the pneumatic cylinder can be set to certain values corresponding to a known resistance by the setting of the compressor (the higher the pressure of the compressed air produced by the compressor, the higher the resistance of the pneumatic cylinder, and the higher the equivalent resistance).
  • the resistance mechanism can be a hydraulic cylinder and the air a fluid.
  • the resistance mechanism is an electric motor and braking system comprising an electric motor and a clutch assembly.
  • the electric motor imparts a force through the brake, which can correspond to a known resistance by the power supplied to the motor or to the brake.
  • Pushing or pulling on the pushing and pulling means causes a force in a rotational direction counter to the rotational direction of the motor and brake, creating a counterforce that can be measured in an equivalent weight resistance.
  • the resistance mechanism does not need to be weight-based.
  • the invention also can be a combination of a conventional treadmill for forward or rearward walking and running and the pushing and pulling motion treadmill.
  • the lower base housing the treadmill belt motor and the weight resistance mechanism can be a relatively larger structure sitting under and supporting the treadmill or a relatively smaller structure from which the treadmill belt and platform extend.
  • the elevation motor or means for raising and lowering the treadmill belt platform for incline and decline operation can be located within the lower base housing.
  • the elevation motor or means can be located in a separate relatively smaller structure attached to the end of the treadmill platform opposite the end of the treadmill platform attached to the lower base housing.
  • the internal mechanical components of the treadmill are similar to (or can be similar to or the same as) the internal mechanical components of known treadmills.
  • the treadmill comprises an endless belt looped about rollers or pulleys so as to provide a platform on which the user can stand, walk and/or run.
  • a deck below a portion of the belt supports the belt and the user.
  • a belt motor cooperates with the belt and/or the rollers or pulleys to move the belt, thus creating a moving platform on which the user can walk or run for the exercise regimen.
  • An incline motor cooperates with the platform, the deck, the rollers or pulleys, the front support legs, and/or the rear support legs to incline the belt to simulate a hill.

  • Treadmill 10 has a lower base 12 housing the internal mechanical components of treadmill 10. Projecting upwardly from base 12 is console support structure 200 to which moment arm 314 is pivotally connected or supported. Pushing arm 14, on which pushing handle 16 is mounted, is operatively connected to moment arm 314, which is part of resistance mechanism 300.
  • Console support structure 200 preferably is fixedly attached to base 12 and comprises two uprights 210 that are secured to base 12 at or along the sides of base 12 at points proximal to the front end of base 12.
  • Console 212 extends generally horizontally between uprights 210 and preferably is located at or proximal to the top of uprights 210.
  • console 212 in a preferred embodiment is fixedly attached to console support structure 200 and in one embodiment is unmovable or at least not movable as part of the exercise regimen.
  • the combination of console support structure 200, uprights, 210 and the various structural components thereof also are referred to as the frame.
  • Moment arm 314 extends generally horizontally between uprights 210 and can be pivotally attached to one upright 210, thus allowing moment arm 314 to pivot upwards and downwards generally between uprights 210.
  • Rod supports 253 comprising bearings are one means by which moment arm 314 can be pivotally secured via pivot rod 252 to upright 210.
  • Rod supports 253 can be attached directly to upright 210 or can be mounted on upright 210 via brackets or the like. For example, in some circumstances, it can be advantageous to mount moment arm 314 in front of console support structure 200 rather than directly between uprights 210.
  • additional brackets would support rod supports 253 at a position in front of uprights 210, that is, at a position on the opposite side of uprights 210 from user U and treadmill belt 20, or at a position behind uprights 210, that is, at a position on the same side of uprights 210 as user U and treadmill belt 20.
  • One end of moment arm 314 can extend though one of the uprights 210 (the upright that moment arm 314 is not pivotally attached to) such that moment arm 314 can be operatively connected to pushing handle 16.
  • moment arm 314 is mounted in front of console support structure 200, then moment arm 314 would pass in front of and not through upright 210.
  • Moment arm 314 preferably is mounted more proximal to the bottom of uprights 210, that is, more proximal to base 12. Although this location is generally arbitrary, this location has been found to be preferable from a mechanics standpoint in that this location allows the resistance mechanism 300 to be mounted lower on the treadmill 10, thus providing a lower center of gravity and greater stability for the treadmill 10.
  • Pushing arm 14 can comprise one, two or more sections, and preferably two sections, not including pushing handle 16 as a section. Pushing arm 14 sections preferably are rigidly attached to each other, or are a single bent or straight structure, and also preferably are rigidly attached to pushing handle 16.
  • Pushing arm 14 can be a rod-like, tubular, flat rigid or semi-rigid structure, or the equivalent, that is pivotally connected to console arms 212A. Pushing arms 14 preferably are pivotally attached to console arms 212A such that operational movement of pushing handles 16/pushing arms 14 actuates resistance mechanism 300. Pushing arms 14 also can be pivotally attached to the treadmill base 12, the uprights 210, or the console 212 with minor engineering changes.
  • Pushing handle 16 is mounted generally towards the distal end of console arms 212A (distal to console 212), which also is proximal to user U when user U is in the correct position for operating the treadmill 10.
  • the combination of pivot points 28 and the rotation of pushing arm 14 allows desired motion of pushing arm 14 and pushing handle 16 relative to user U.
  • the movable pushing handle 16 solves the problem of allowing the user U to activate the resistance mechanism 300, while at the same time maintain a position on the treadmill 10 and conduct the exercise regiment by pushing against an adjustable but constant and static resistance.
  • FIGs. 2 and 3 are set of side views of the treadmill 10 in which a user U would be operating the treadmill 10 in a generally flat or level pushing simulation. In this position, user U would be simulating a generally level surface pushing motion and walking or running forwards and pushing on and moving pushing handle 16, and thus pushing against resistance mechanism 300.
  • FIG. 2 the invention is shown in a resting position, meaning resistance mechanism 300 is not providing resistance to user U
  • FIG. 3 the invention is shown in an operating position, meaning resistance mechanism 300 is providing resistance to user U, as disclosed in more detail herein.
  • FIGs. 1 As can be seen in FIGs.
  • pushing handle 16 (and pushing arm 14) is operationally connected to resistance mechanism 300 via main cable 302, pulley system comprising pulleys 304, 306, 308, and secondary cable 326.
  • the pushing handle 16/pushing arm 14 combination can be structured in various configurations. In the embodiment generally shown in the figures and use as the illustrative embodiment in this specification, there are two separate pushing handles 16 each connected to a separate pushing arm 14, with one set of pushing handle 16A pushing arm 14A being attached to a first console arm 212A (the left side) and another set of pushing handle 16B/pushing arm 14B being attached to a second console arm 212B (the right side). In an embodiment illustrated in and disclosed in connection with FIG. 20, there is only one pushing handle 16, namely a pushing bar 16C, connected to two pushing arms 14. In another embodiment, there may only be one set of pushing handle 16/pushing arm 14 located on either the first console arm 212A or on the second console arm 212B.
  • Main cable 302 is attached at one end to first pushing arm 14A and is attached at another end to second pushing arm 14B. In between pushing arms 14A, 14B, main cable 302 travels through directional pulleys 304, console pulleys 306, and lifting pulley 308. Secondary cable 326 operatively connects lifting pulley 308 with the non-pivoting end of moment arm 314, and therefore with resistance mechanism 300, and is attached at one end to lifting pulley frame 308A and is attached at another end to moment arm 314. As moment arm 314 is being pivoted by the action of secondary cable 326 attached to the non-pivoting end of moment arm 314, moment arm 314 in this embodiment is referred to as a modified moment arm.
  • Directional pulleys 304 and console pulleys 306 can be and preferably are fixed class 1 pulleys that are mounted on or within console 212 or console arms 212A, 212B to direct and redirect the force of main cable 302 and do not move, except to rotate as main cable 302 moves over them.
  • Lifting pulley 308 can be and preferably is a movable class 2 pulley to transform the force of main cable 302 to secondary cable 326.
  • all pulleys 304, 306, 308 can be fixed pulleys or movable pulleys, or a combination of fixed and movable pulleys, depending on the relative force needed to operate the resistance mechanism 300, this combination of fixed and movable pulleys provides a suitable transformation of the user's U energy to the actuation of the resistance mechanism 300.
  • Weight 316 is operationally connected to moment arm 314 and along with moment arm 314 causes a moment about pivot point 322, thus urging a rotation of moment arm 314 about pivot point 322.
  • moment arm 314 acts on secondary cable 326 by pulling secondary cable 326 downward or at least imparting a downward tensional force on secondary cable 326.
  • the downward force on secondary cable 326 is imparted to lifting pulley 308, which imparts a tensional force on main cable 302.
  • the tensional force on main cable 302 is imparted to pushing arm(s) 14 and pushing handle(s) 16, which imparts a pushing force on the user U grasping the pushing handle(s) 16. This creates the pushing sensation and weight resistance of the invention.
  • FIG. 4 is a front view of another embodiment of the invention structured with a side mounted moment arm as the exemplary resistance mechanism 300 and illustrating the relationship between the various major components of the device.
  • moment arm pivot rod 252 is elongated and extends generally horizontally between uprights 210 and can be pivotally attached to each upright 210, thus allowing moment arm pivot rod 252 to rotate axially generally between uprights 210.
  • Bearings 214 are one means by which moment arm pivot rod 252 can be rotationally secured or journaled to uprights 210. Bearings 214 can be attached directly to uprights 210 or can be mounted on uprights 210 via brackets or the like.
  • FIG. 5 is a side view of the treadmill 10 embodiment shown in FIG. 4 showing user U operating the treadmill 10 in a generally flat or level pushing simulation. In this position, user U is simulating a generally level surface pushing motion and is walking or running forwards and pushing on and moving pushing handle 16, and thus pushing against resistance mechanism 300. Resistance mechanism 300 is shown in an operating position, meaning resistance mechanism 300 is providing resistance to user U.
  • Pushing handles 16 are operationally connected to resistance mechanism 300 via main cable 302, pulley system comprising pulleys 304, 306, 308, and secondary cable 326.
  • main cable 302 is attached at one end to first pushing arm 14A and is attached at another end to second pushing arm 14B.
  • main cable 302 travels through directional pulleys 304, console pulleys 306, and lifting pulley 308.
  • Secondary cable 326 operatively connects lifting pulley 308 with cam 312, and therefore with resistance mechanism 300, and is attached at one end to lifting pulley frame 308A and is attached at another end to cam 312.
  • Moment arm resistance mechanism 300 as illustratively shown in FIGs. 5 and 6 comprises cam 312, moment arm 314, weight 316, weight adjusting drive 318, weight adjusting mechanism support 320, pivot point 322 (corresponding to the end of the moment arm pivot rod 252), and weight adjusting motor 324.
  • Moment arm 314 is secured to moment arm pivot rod 252 and extends generally normal to the axis of moment arm pivot rod 252.
  • moment arm 314 acts as a cantilever extending from moment arm pivot rod 252, and the combination of moment arm 314 and moment arm pivot rod 252 can rotate about the axis of moment arm pivot rod 252.
  • moment arm 314 is a generally flat runway on which weight 316 can roll, and can be termed an open arm.
  • Weight 316 causes a moment about pivot point 322, thus urging a rotation of moment arm pivot rod 252 about its axis.
  • cam 312 also is rotationally urged in the same direction, thus acting on secondary cable 326 by pulling secondary cable 326 downward or at least imparting a downward tensional force on secondary cable 326.
  • the downward force on secondary cable 326 is imparted to lifting pulley 308, which imparts a tensional force on main cable 302.

In this position, user U is simulating a pushing motion and is walking or running forwards and pushing on and moving pushing handles 16, and thus pushing against resistance mechanism 300.
  • the invention can be operated in an inclined position in which the front (console end) of the treadmill 10 is elevated relative to the rear of the treadmill 10, to allow the simulation of pushing a load uphill.
  • a second embodiment of moment arm resistance mechanism 300 as illustratively shown in FIG. 6 comprises cam 312, moment arm 314, weight 316, weight adjusting drive 318, pivot point 322 (corresponding to the end of the moment arm pivot rod 252), and weight adjusting motor 324.
  • Moment arm 314 can be secured to moment arm pivot rod 252 via weldments 344, and extends generally normal to the axis of moment arm pivot rod 252.
  • moment arm 314 acts as a cantilever extending from moment arm pivot rod 252, and the combination of moment arm 314 and moment arm pivot rod 252 can rotate about the axis of moment arm pivot rod 252.
  • base 12 can comprise a separate motor housing 32 and belt platform 34.
  • Motor housing 32 contains the various conventional motors and associated components for moving belt 20 and for raising and lowering base 12 and belt platform 34 for inclined exercising.
  • each of the above disclosed elements can be located as desired in either motor housing 32 or belt platform 34 by the person of ordinary skill in the art.
  • the inclination of belt 20 is accomplished by an incline motor raising the front end of base 12 relative to the rear end of base 12, in a manner well known in the art.
  • an illustrative inclination mechanism is provided to permit inclination of belt platform 34 and belt 20.
  • Illustrative lift mechanisms include a leg lift, comprising an incline motor and front legs. Such lift mechanisms are known in the treadmill art.
  • Weight adjusting motor 324 can be a bidirectional electric motor. Preferably, weight adjusting motor 324 is located proximal to pivot point 322 as weight adjusting motor 324 does have some weight and, if located on the free end 330 of moment arm 314, would impart a certain amount of weight to moment arm 314 creating an increased base moment about pivot point 322. Weight adjusting motor 324 can be selected to move weight 316 relative to or along moment arm 314 away from or towards pivot point 322, and therefore must be of sufficient power to accomplish this task. Alternatively, weight adjusting motor 324 can be mounted outside of moment arm 314 and a hole can be located on the end of moment arm 314 to allow weight adjusting drive to extend therethrough and into the interior of moment arm 314 to cooperate with weight 316.
  • Weight 316 can be any structure having mass.
  • weight 316 is a solid mass having an internal threaded passage extending from a first side to an opposite second side or, as disclosed in connection with FIG. 8, a combination of an internal passage 352 and threaded nut 350.
  • Internal threaded passage or nut 350 cooperates with the screw thread on weight adjusting drive such that when weight adjusting drive is turned or rotated by weight adjusting motor 324, weight 316 is forced to move linearly.
  • Weight 316 can comprise optional wheels 332 on the bottom and optionally on the top that cooperate with moment arm 314 to allow the easier movement of weight 316 along moment arm 314.
  • the complimentary screw threads cooperate and force weight 316 to move linearly along or relative to moment arm 314.
  • the amount or level of pushing force imparted to the user U can be adjusted by moving weight 316 along the moment arm 314.
  • pushing force it is meant the counterforce created by the resistance mechanism 300 in response to the user pushing on pushing handles 16.
  • the pushing force is equal to and opposite the force created by the user pushing on pushing handles 16. If weight 316 is proximal to pivot point 322, then the moment created by weight 316 is minimal and therefore the amount or level of pushing force imparted to the user U is minimized. If weight 316 is distal to the pivot point, then the moment created by weight 316 is maximized and therefore the amount or level of pushing force imparted to the user U is maximized.
  • Conventional controls on movable pushing handles 16 or fixed console 212 or elsewhere operate weight adjusting motor 324 so as to move weight 316 to the desired position along moment arm 314 for imparting the desired amount or level of pushing force to the user U as the user U pushes on pushing handle 16.
  • Main cable 302 and secondary cable 326 can be of any flexible structure, such as a rope, a chain, a belt, monofilaments, braided wires, flexible materials, and other suitable equivalents, that allow a transfer of force between pushing handle 16/pushing arm 14 and resistance mechanism 300, and is not limited to a standard cable.
  • main cable 302 can be directed around one or more pulleys 304, 306, 308 to direct or redirect main cable 302 between pushing arm 14 and resistance mechanism 300, and to prevent main cable 302 from becoming entangled in the internal mechanical components of treadmill 10.
  • the degree of resistance can be controlled by user U.
  • user U would be simulating pushing a weight (the force created by moment arm 314 as transferred to user U) and the exercise regimen would be similar to walking or running forwards while pushing an object of a weight comparable to the setting of resistance mechanism 300.
  • the higher the setting of resistance mechanism 300 that is, with weight 316 further from pivot point 322), the heavier the simulated object being pushed. With this arrangement, it is therefore possible to vary the weight resistance being pushed during the exercise regimen.
  • the resistance is constant and static as transferred to pushing handles 16, thus imparting a constant and static resistance to the user U as long as the user U maintains the resistance setting.
  • the resistance setting can be changed (increased, decreased) during the exercise regimen, at which point the resistance would be changed to the new resistance level, and would remain at that level until changed by the user U.
  • FIGs. 2 and 5 A comparison of the position of pushing arm 14 in FIGs. 2 and 5 versus FIGs. 3 and 6, respectively, shows how pushing arm 14 can move.
  • Pushing arm 14 is shown in the at rest position in FIGs. 2 and 5, and in the operational position (partially pivoted) in FIGs. 3 and 6.
