Definitions

  • This invention relates to the general technical field of exercise, physical fitness and physical therapy equipment and machines and to the more specific novel technical field of a mechanically, electrically and electronically operated reverse treadmill machine designed to simulate a dragging or pulling motion when operated by the user.
  • 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 diagnostic and therapeutic purposes.
  • the person on the exercise treadmill normally can perform an exercise routine at a relatively steady and continuous level of physical activity or at a variable level of physical exercise including varying both the speed and incline of the treadmill during a single session.
  • Exercise treadmills typically have an endless running surface extending between and movable around 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 belt 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 a deck or support surface beneath the belt, such as a plastic or metal panel, to provide the required support.
  • the 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.
  • 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 known 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 hand controls in known exercise treadmills are structured to complement simulated forward motion.
  • any specific exercise treadmill that is structured to allow the user to comfortably simulate a dragging or pulling motion; that is, a backwards walking motion either on a level plane or uphill.
  • the inventor is unaware of any specific exercise treadmill that has an adjustable weight resistance against dragging or pulling so as to simulate dragging or pulling of a load.
  • a simulated dragging or pulling motion can be useful for exercising and developing different groupings of muscles and for providing an aerobic workout.
  • an exercise treadmill simulating a dragging or 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 an exercise treadmill for simulating the dragging or pulling of an object on a level surface, up an incline or down a decline as defined in claim 1.
  • the treadmill has a lower base housing the internal mechanical components, a pivot arm on which a hand controller is mounted, and a weight resistance means located within the lower base.
  • the weight resistance means is operatively connected to the pivot arm via a cable.
  • 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 hand controller.
  • the degree of weight resistance of the weight resistance means can be controlled by the user to simulate dragging or pulling a weight such that the exercise regimen is similar to walking or running backwards while dragging or pulling an object of a weight comparable to the setting of the weight resistance means.
  • the weight resistance means can be an adjustable spring or hydraulic or pneumatic cylinder, a spring with a known spring constant or a hydraulic or pneumatic cylinder with a known resistance, a flexible rod with a known elastic modulus, or a frictional coupling with known coefficients of friction.
  • the internal mechanic 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 or rear legs to incline the belt to simulate a hill.

  • FIG. 1 is a perspective view of the invention illustrating the relationship between the various major components of the device.
  • Treadmill 10 has a lower base 12 housing the internal mechanical components of treadmill 10. Projecting upwardly from base 12 is pivot arm 14 on which hand controller 16 is mounted.
  • Pivot arm 14 can comprise one, two, more pivot arm sections. As illustrated in FIG. 1 , pivot arm 14 comprises two pivot arm sections, upper pivot arm 14A and lower pivot arm 14B, such that pivot arm 14 is self-aligning for users U of different heights and body builds. Additionally, the use of a two-part pivot arm 14, or a multi-part pivot arm 14, provides for a more biometrically acceptable pulling motion and to position pivot arm 14 as far away from user U (shown in FIGs.
  • First mounting means 28 pivotally attaches upper pivot arm 14A to lower pivot arm 14B.
  • Hand controller 16 is mounted on the end of upper pivot arm,14A distal from lower pivot arm 14B, which also is proximal to user U when user U is in the correct position for operating the treadmill 10.
  • Second mounting means 30 attaches hand controller 16 to upper pivot arm 14A and can be a static or motionless connection, with hand controller 16 rigidly connected to upper pivot arm 14A, or a dynamic or moving connection, with hand controller 16 movably connected to upper pivot arm 14A, such as in a two-dimensional pivoting or three-dimensional joystick configuration.
  • the combination of pivot arm 14 and hand controller 16 provides user U with a means of support either during the entire exercise period or for an initial period until user U has assimilated himself or herself to the speed of the treadmill.
  • the combination of first mounting means 28 and second mounting means 30 allows desired motion of pivot arm 14 and hand controller 16 relative to user U.
  • pivot arms 14 there can be two pivot arms 14, one for each hand of user U. If two pivot arms 14 are used, the controls on hand controller 16 can be on one or the other of pivot arms 14, or split between the two pivot arms 14. Further, the use of two independent pivot arms 14 can simulate the arm-swinging motion that normally occurs during walking or running, which may be advantageous to user U.
  • Hand controller 16 can include electronic controls and information displays that typically are provided on exercise treadmills for purposes such as adjusting the speed and incline of treadmill 10, the time user U has been operating treadmill 10 and/or the time left in a set exercise regimen, user's U heart rate, the simulated load being dragged or pulled, on and off buttons, and an emergency off button, and other functions, as will be discussed later in connection with FIGs. 6 and 7 .
  • Various step off platforms, such as side step offs 22, front step offs 24 and rear step-offs 26, can be included in various configurations both to allow user U easy access to the treadmill 10 and to provide safety platforms for user U to step off treadmill 10 onto a non-moving platform, as will be discussed later in connection with FIG. 5 .
  • Attached to lower pivot arm 14B and extending between lower pivot arm 14B and a weight resistance means 46 shown in more detail in FIG. 4 is weight resistance cable 18.
  • belt 20 In normal operation, user U will step onto belt 20 and grasp hand controller 16, positioning himself or herself generally centrally on belt 20 so as to face the hand controller 16. As belt 20 begins to move, as will be discussed later, user U will start a rearward walking or running motion towards the rear of treadmill 10, with belt 20 moving accordingly, such that user U will remain generally in the same position centrally on belt 20 as treadmill 10 is operating.
  • treadmill 10 may be set up to begin to move automatically at a speed according to a value entered from hand controller 16. The pace of the walking or running motion may be increased or decreased depending upon the speed of belt 20.
  • the speed of belt 20 can be controlled by the adjustment of the controls on hand controller 16, along with the adjustment of the inclination of treadmill 10 and other functions and features, as will be discussed later in connection with FIGs. 6 and 7 .
  • Belt 20 also can comprise two belts, one for each foot, as an alternative.
  • FIG. 2 is a side view of the invention showing user U operating the treadmill 10 in a flat or level dragging or pulling simulation. In this position, user U is simulating a level surface dragging or pulling motion and is walking or running backwards and pulling on hand controller 16, and thus pulling against weight resistance means 46.
  • FIG. 3 is a side view of the invention showing user U operating the treadmill 10 in an inclined dragging or pulling simulation. In this position, user U is simulating an inclined uphill dragging or pulling motion and is walking or running backwards and uphill and pulling on hand controller 16, thus simultaneously pulling against weight resistance means 46 and moving uphill.
  • hand controller 16 and pivot arm 14 via first mounting means 28 and second mounting means 30 allow the appropriate motion of pivot arm 14 hand controller 16 relative to user U for self-alignment and for proper and comfortable operation of treadmill 10.
  • pivot arm 14 pivotally attached to base 12
  • user U grasps hand controller 18
  • user U can move hand controller 18 upwards and downwards, and towards or away from user U, so as to place hand controller 18 in a position most comfortable to user U.
  • the pivot points are freely pivotable, hand controller 18 in effect self-aligns to an appropriate position relative to user U simply upon being grasped by user U.
  • additional pivot points such as by making pivot arm 14 multi-sectional, can enhance this self-aligning feature.
  • base 12 can comprise a separate support platform 32 and belt platform 34.
  • the main support for treadmill 10 along with belt motor 40 (shown in FIG. 4 ), incline motor 42 (shown in FIG. 4 ) and weight resistance means 46 (shown in FIG. 4 ) preferably are located in support platform 32, whereas belt 20 and belt movement means (disclosed in connection with and shown in FIG. 4 ) preferably are located in belt platform 34.
  • each of the above disclosed elements can be located as desired in either support platform 32 or belt platform 34 by the engineer of ordinary skill in the art.

  • the inclination of belt 20 is accomplished by incline motor 42 raising the rear end of base 12 relative to the front end of base 12, in a manner well known in the art.
  • FIG. 4 is a side sectional view of the invention showing a schematic of the internal mechanical components of the treadmill 10.
  • Treadmill 10 comprises an endless belt 20 looped about rollers or pulleys 36. Rollers or pulleys 36 are rotatably secured within base 12 such that belt 20 can continuously travel about rollers or pulleys 36. Located between rollers or pulleys 36 and within the endless loop of belt 20 is deck 38 for supporting the top run 20A of belt 20. Specifically, as when user U steps on belt 20, belt 20 is pressed against deck 38 to support user U.
  • Belt motor 40 cooperates with belt 20 and/or rollers or pulleys 36 to move belt 20.
  • Incline motor 42 cooperates with belt platform 34, deck 38, rollers or pulleys 36 or rear legs 44 to incline belt 20.
  • Weight resistance means 46 cooperates with pivot arm 14 via cable 18.
  • Cable 18 can be of any structure, such as a rope, a chain, a belt, monofilaments, braided wires, and other suitable equivalents, that allow a transfer of force between pivot arm 14 and weight resistance means 46, and is not limited to a standard cable.
  • FIG. 4 A representative drive assembly for belt 20 is schematically illustrated in FIG. 4 .

  • Front roller or pulley 36A and rear roller or pulley 36B are positioned substantially parallel to each other.
  • Belt 20 is looped around rollers or pulleys 36 so as to allow belt 20 to move continuously about rollers or pulleys 36, thus forming upper run 20A and lower run 20B.
  • User U steps on belt 20 during normal operation of treadmill 10, causing belt 20 to bend under the weight of user U.
  • Belt 20 is supported for a portion of its length, and for a substantial portion of upper run 20A, between rollers or pulleys 36 by deck 38.

  • FIG. 4 also schematically illustrates an example weight resistance means 46 for the treadmill 10.
  • Weight resistance means 46 is operatively connected to pivot arm 14 via cable 18.
  • Cable 18 can be directed around one or more pulleys 60 to prevent cable 18 from becoming entangled in the internal mechanical components of treadmill 10.
  • cable 18 is attached to lower pivot arm 14B, travels around pulley or pulleys 60 if necessary, and attaches to weight resistance means 46.
  • user U grips hand controller 16 and starts belt 20 moving
  • user U begins to walk or run in a simulated backwards direction relative to hand controller 16, causing user U to pull on hand controller 16.
  • This pulling transfers to pivot arm 14, as hand controller 16 is attached to pivot arm 14, thus pulling on cable 18, which in turn pulls on weight resistance means 46.
  • the degree of weight resistance can be controlled by user U. In the lowest setting, it can be possible for user U to pull pivot arm 14 all the way to a stop (not shown) preventing pivot arm from moving any farther. At such a setting, user U would be simulating dragging or pulling little or no weight and the exercise regimen would be similar to walking or running backwards, and pivot arm 14 would provide user U with stability. In other settings, weight resistance means 46 can be set high enough to prevent user U from pulling pivot arm 14 all the way to the stop (not shown). At such settings, user U would be simulating dragging or pulling a weight and the exercise regimen would be similar to walking or running backwards while dragging or pulling an object of a weight comparable to the setting of the weight resistance means 46. The higher the setting of the weight resistance means 46, the heavier the simulated object being pulled.
  • the degree of weight resistance chosen by user U is adjustable from controls on hand controller 16. With this arrangement, it is therefore possible to vary the weight resistance being dragged or pulled during the exercise regimen.
  • weight resistance means 46 can be an adjustable spring or hydraulic cylinder, a spring with a known spring constant or a hydraulic or pneumatic cylinder with a known resistance, a flexible rod with a known elastic modulus, or a frictional coupling with known coefficients of friction.

As discussed later, the weight resistance means 46 can be of many different forms, known or future developed, preferably so long as weight resistance simulating dragging or pulling is provided.
  • FIGs. 4A and 4B illustrate adjustable springs or springs with known spring constants.
  • FIG. 4A illustrates the use of spring 70 in tension.
  • adjustment mechanism 72 is shown, a spring of known spring constant can be used without adjustment mechanism 72.
  • First end 70A of spring 70 is attached to base 12 and second end 70B of spring 70 is attached to cable 18. In tension, pulling on cable 18 in the direction of arrow P would stretch spring 70, placing it in tension.

Such displays are known in the treadmill art.
  • Additional displays can include a mile display to display the simulated distance traveled by user U during the exercise regimen, a calorie display to display the current rate of user U calorie expenditure or the total calories expended by user U during the exercise regimen.
  • hand controller 16 can include an input key pad with which user U can communicate with a microprocessor that operates treadmill 10 so as to operate treadmill 10 as well as set the parameters for exercise regimens. Also included on hand controller is or can be on-off buttons, emergency stop button 100, increase buttons 102 to increase a parameter, decrease buttons 104 to decrease parameters, and other functional input devices. All of these are known in the treadmill art.
  • hand grips 106 also can comprise input means (not shown) for reading user's U heart rate, as is known in the art.
  • Treadmill 10 utilizes a known microprocessor (not shown) to control and operate the various features of the invention.

  • the inclination of belt 20 also is controlled by the microprocessor.
  • the signals are transmitted to and from the microprocessor to the hand controller 16 displays 90, 92, 94, 96, 98 (and others, if present), and are operatively connected to the switches 100, 102, 104 (and others, if present) and the specific elements, such as belt motor 40, incline motor 42, and weight resistance means 46.
  • the use of this type of microprocessor is well known in the treadmill art.
  • FIG. 8 is a side view of the invention with an optional rear safety arm 108 to help prevent user U from inadvertently stepping off the rear of treadmill 10.
  • Rear safety arm 108 can comprise pad 110 attached to upright 112, upright 112 being attached to base 12.
  • a second controller (not shown) can be located on rear safety arm 108 or pad 110.
  • Such a second controller could be used to operate treadmill 10 in a more conventional manner as a forward walking treadmill. With such a configuration, user U would in effect be standing on belt 20 facing rearward towards rear safety arm 108 with the motion of belt 20 allowing forward walking and control of treadmill 10 would be accomplished via second controller.
  • FIG. 9 is a side view of the invention with an optional rear step-off 26 platform on which user U can step if exiting treadmill 10 from the rear.
  • Optional side step offs 22 are the most preferable step off features, with optional front step offs 24 also being preferable due to pivot arm 14 pivoting forward in the at rest position.
  • Rear step offs 26 are optional and provide an additional measure of safety.
  • FIG. 9 also shows treadmill 10 in an inclined operational position using belt platform 34 and support base 32.
  • FIG. 10 is a side sectional view of the invention with an optional rear step-off 26 platform showing an alternate configuration of the internal mechanical components illustrating the relationship between the various major components of the device.
  • FIG. 10 is similar to FIG. 4 in this regard, but with the shape of the rear of base 12 altered to accommodate rear step off 26.
  • the invention also can comprise additional optional features.
  • the invention can comprise a safety mechanism to prevent user U from speeding up the movement of belt 20 due to the weight resistance of the weight resistance means 46, and from speeding up the movement of belt 20 to a speed faster than what is shown on the hand controller 16 speed display 98.
  • treadmill 10 can further comprise a means for preventing belt 20 from running out from under user U should either user U move too fast relative to belt 20 or belt 20 move too fast relative to user U. This also would help prevent the force of user's U foot plant from undesirably increasing the speed of belt 20. Clutches attached to belt 20 or axles 48, 50 can be used, among other known mechanisms.
  • the step offs 22, 24, 26 optionally can be and preferably are of a substantial width to allow for a wider platform for user U to step onto or step off of treadmill 10.
  • Side rails and kill switches also can be used.
  • Heart rate monitors can be used, and the microprocessor can be configured to allow for heart rate monitoring and for the adjustment of belt 20 speed and incline and the level of weight resistance to maintain a desired heart rate.
  • the present invention accomplishes a different exercise regimen than an aerobic walking or running workout.
  • belt 20 travels in the opposite direction than the belt on known treadmills to provide the basis for the dragging or pulling motion.
  • a weight resistance means 46 in combination with a walking or running motion in general and a backwards walking or running motion in particular provides a more complex exercise regimen. It has been found that the combination of walking or running backwards in conjunction with the simulation of dragging or pulling a load provides a useful aerobic and/or anaerobic work out and can strengthen various muscles and muscle groups, specifically leg muscles and the gluteus maximus and arm, chest and back muscles.
