Abstract
A treadmill having a motorized treadbase and a folding handrail fold is with respect to the treadbase such that the treadmill achieves a low profile when the handrail is in a folded position. The treadmill includes: (i) a treadbase, the treadbase comprising first and second rollers and an endless belt movably trained about the first and second rollers; (ii) a motor coupled to the treadbase, the motor also being movably coupled to the first roller such that the motor selectively turns the first roller, thereby causing the belt to move; and (iii) a handrail pivotally coupled to the treadbase, the handrail selectively folding with respect to the treadbase. In a preferred embodiment, the treadmill is less than about 8 inches in height when the handrail is in a folded position.
Description




BACKGROUND OF THE INVENTION




1. The Field of the Invention




This invention is in the field of exercise equipment. More specifically, this invention is in the field of motorized, folding treadmills.




2. The Relevant Technology




The desire to improve health and enhance cardiovascular efficiency has increased in recent years. This desire has been coupled with the desire to exercise in locations that are compatible with working out within a limited space such as within an individual's home or exercise gym. This trend has led to an increased desire for the production of exercise equipment.




Treadmills are a popular form of exercise equipment. Many varieties of treadmills have been produced in order to attempt to satisfy the high demand for treadmills. Folding treadmills have been particularly popular in recent years because of the ability of the folding treadmill to compact into a smaller space when in a storage position. Such folding treadmills efficiently use space within a home or exercise gym. However, even folding treadmills are not always convenient to place under existing furniture or within a small space within an office, home or gym.




Motorized treadmills, which feature a belt driven by a motorized assembly, have also become popular in recent years because they enable a user to exercise at a set, desired speed. However, due to the size of the motor and other components within the treadbase of such treadmills, typical motorized treadmills tend to have a high profile—even when a handrail thereof folds with respect to the treadbase. The size of the motor and related components is often due to the large diameter of a flywheel that is employed to achieve a desired inertia while a user is ambulating on the treadmill. The large size of the flywheel can prevent treadmills from being conveniently moved under a piece of furniture or into a small space within the home, office, or gym of a user.




Furthermore, treadmills are typically difficult to move into a desired space. Even treadmills with wheels thereon must typically be tipped upward and then rolled at an angle into a space where storage is desired. Such treadmills typically feature fixed wheels which rotate about a single axis, therefore making it difficult to move the treadmills from side to side, for example. Another problem with the art relates to the difficulty of achieving a desired, set position for a handrail of a treadmill.




Another problem within the art relates to the cumbersome use of wiring extending between a user interface consul and a motor of the treadmill. Such wiring can be accidentally cut, for example, if not handled carefully, and often requires the manufacturer to thread the wiring through moving parts, such as between the handrail and the treadbase of the treadmill.




SUMMARY OF THE INVENTION




It is therefore an object of the invention to provide a low profile treadmill.




It is another object of the invention to provide a treadmill that can be selectively rolled or slid under a variety of different objects or pieces of furniture within a home, office, or exercise gym.




It is another objection of the invention to provide a treadmill that readily slides on a variety of different services and in a variety of different directions.




It is another object of the invention to provide a treadmill that readily rolls on a variety of different surfaces and in a variety of different directions.




It is another objection of the invention to provide a reliable moving handrail on a treadmill that can be selectively placed into a desired position with respect to a treadbase.




It is another object of the invention to provide a treadmill having a user interface console that readily transmits information without the use of wires extending through moving parts of the treadmill.




It is another object of the invention to provide a treadmill that can be conveniently grasped by a user when moving the treadmill to a desired location.




The present invention relates to a low-profile motorized, folding treadmill that has a height of less than about eight inches in a folded position. Since the treadmill can be folded to such a low profile, the treadmill can be readily moved under a bed or other piece of furniture within a home, office, or exercise gym. Treadmills having a height of less than about seven inches, or less than about six inches in the folded position are also available according to the present invention.




This low-profile dynamic is particularly advantageous because the treadmill is a motorized, folding treadmill. Thus, the advantages of a motorized belt and a low profile folding handrail can be achieved in the same unit. A variety of different motor assemblies are disclosed which assist the user to achieve a desired inertia potential, yet feature flywheels with a relatively small diameter, thereby decreasing the overall height of the folded treadmill.




To enhance the user's ability to move the treadmill, the treadmill can be glided on gliding members or rolled on pivoting wheels which pivot about a vertical axis and roll about a horizontally oriented axis. Thus, the treadmill can be slid or rolled in a front to back, side to side or diagonal orientation while the treadbase remains in a folded, substantially horizontal orientation.




Also, to enhance a user's ability to move the treadmill, handles on the treadbase and/or handrail are disclosed that enable a user to more conveniently grasp the treadmill during movement. The handles may be comprised of a variety of different members, such as a strap coupled to the treadbase, (e.g., the proximal end of the treadbase), a grip coupled to the treadbase, a recess within the treadbase which is defined by a configuration that can be grasped, and a variety of other handle embodiments.




As another unique advantage of the present invention, a handrail positioning assembly is disclosed comprising a shock which allows the user to selectively move the handrail to a desired position, and then move the handrail to another position by actuating a release mechanism. The shock reliably maintains the handrail in a fully upright position, a folded position, and a variety of positions therebetween.




A user console is disclosed which allows a user to achieve wireless communication between the user console, the treadmill belt motor, an incline motor, and other components of the treadmill. The user console folds when the treadmill is in the folded position.




Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other objects and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




With reference now to

FIGS. 1-2

, a low profile, folding, selectively inclining motorized treadmill


10


of the present invention is shown. Treadmill


10


supports a user ambulating thereon in a running or walking mode. Treadmill


10


comprises a selectively inclining treadbase


12


, and a folding handrail


14


. A user console


16


is pivotally coupled to handrail


14


.




Treadmill


10


features a variety of different advantages. Folding handrail


14


folds with respect to treadbase


12


from the operational position of

FIG. 1

into a low-profile folded position shown in FIG.


2


. By folding into such a tight, compact unit, treadmill


10


can be readily placed under a bed or other piece of furniture within a home, office, or gym.




As another advantage of treadmill


10


, user interface console


16


is in wireless communication with the treadmill motor, the inclination motor, and any other components which operate moving parts within treadmill


10


. Thus, a wire is not required to extend between console


16


and treadbase


12


in order to operate treadbase


12


.




As yet another advantage of treadmill


10


, user console


16


selectively pivots on handrail


14


such that console


16


can be positioned into any desired position and can be flattened when treadmill


10


is in a folded position such as shown in FIG.


2


.




As another advantage of treadmill


10


, handrail


14


features handles


18




a


,


18




b


mounted on handrail


14


that can be employed to selectively move treadmill


10


under a piece of furniture or into a tight space. Handles


18




a


,


18




b


can also be used to raise and lower handrail


14


.




As yet another advantage of treadmill


10


, handles


20




a


,


20




b


are mounted on treadbase


12


thereby assisting in the movement of treadmill


10


to a desired position, particularly when treadmill


10


is in a folded mode. As yet another advantage of treadmill


10


, inclination legs


22




a


,


22




b


are featured, which selectively raise treadbase


12


directly off of a support surface.




Other advantages include a unique handrail positioning assembly comprising a shock for selectively retaining handrail


14


in a desired position as will be discussed in detail below, and unique means for moving treadmill


10


into a desired location such as gliders, pivoting wheels, and fixed wheels and combinations thereof. Each of these will be discussed in greater detail below. In addition, unique motors for use in low profile treadmill


10


are disclosed which enable low profile treadmill


10


to be moved under a desired piece of furniture or into a desired space.




With continued reference now to

FIG. 1

, treadbase


12


has a proximal end


24


, a distal end


26


, and an intermediate portion


28


therebetween. Treadbase


12


comprises a frame


30


and first and second side support rails


32




a


,


32




b


coupled to opposing sides of frame


30


. A housing


34


is coupled to frame


30


covering the treadbase motor and inclination motor. Treadbase


14


rests on a support surface and selectively inclines with respect to the support surface. Rollers


36




a


,


36




b


(

FIG. 3

) are movably coupled to opposing ends of treadbase frame


30


and endless treadmill belt


38


is movably trained about rollers


36




a


,


36




b.







FIG. 1

also demonstrates that handles


20




a


and


20




b


are coupled to proximal end


24


of frame


30


. Handles


20




a


,


20




b


enable a user to conveniently move treadmill


10


, particularly when treadmill


10


is in a folded position. Handles


20




a


,


20




b


each comprise a grip member


21




a


,


21




b


to be grasped by a user. Other embodiments of handles coupled to treadbase


12


include one or more straps coupled to the treadbase, one or more protuberances coupled to the treadbase. The treadbase can have a configuration therein which defines a recess, the configuration capable of being grasped by a user. The user reaches inside the recess to grasp the configuration, which may be a grip or a graspable protrusion or surface.




Handles


20




a


,


20




b


are configured with a glider


33


(

FIG. 7

) on a lower surface thereof. Glider


33


is capable of gliding on a support surface. Thus, treadmill


10


can be glided along a support surface, rather than requiring treadmill


10


to be rolled. Gliding the treadmill


10


is a convenient method for moving the treadmill and is particularly useful when pressing low profile treadmill


10


below an item of furniture, for example. The glider of the present invention is optionally mounted separately from a handle on the frame of the treadbase without being part of the handle assembly


20




a


or


20




b


. However, since handles


20




a


,


20




b


each comprise a grip and a glider, they are advantageous for a variety of different reasons. Gliders of the present invention are mounted on the lower surface of the treadbase such that they contact a support surface.




The gliders of the present invention can be comprised of a smooth polymeric material, such as nylon or PVC, for example, which readily glides on a carpeted surface and/or a felt material, which readily slides on a wood surface. A reversible glider comprising felt on one side and a smooth polymeric material may also be employed in the present invention, as discussed below.




Such gliders can be mounted on the distal comers of treadbase


12


and the proximal comers of treadbase


12


. Optionally, first and second gliders can be mounted on the distal portion of treadbase


12


while a single glider is mounted on the proximal portion of treadbase


12


. Also optionally, a single glider may be mounted on the distal portion of treadbase


12


while first and second gliders are mounted on a proximal portion of treadbase


12


. A variety of other combinations are possible such that one or more gliders are mounted on the lower surface of treadbase


12


to allow gliding of treadbase


12


along a desired surface. Such gliders may be mounted at one or more comers of treadbase


12


or in the middle portion of treadbase


12


or in a variety of different positions on treadbase


12


.




A major advantage of such gliders is that they enable treadmill


10


to be moved while treadmill


10


is flat or substantially flat, rather than requiring a user to tilt the treadmill before moving treadmill


10


from one location to another.




Also as shown in the embodiment of

FIGS. 1 and 2

, handrail


14


(depicted in

FIG. 10

) is pivotally coupled to frame


30


. As shown in

FIGS. 1

,


2


and


10


, handrail


14


comprises first and second upright members


40




a


,


40




b


, an upper cross member


42


coupled therebetween, a lower cross member


92


(

FIG. 3

) coupled therebetween, and a bracket


106


(

FIG. 3

) coupled to the lower cross member


92


However, the handrail of the present invention may have a variety of configurations which allow the handrail to be pivotally coupled to the treadbase of the present invention. For example, the handrail may comprise a single rail which is pivotally coupled to a treadbase.




With continued reference to

FIG. 1

, user interface console


16


is rotatably coupled to upper cross member


42


of handrail. Console


16


comprises a body portion


44


and first and second arms


46




a


,


46




b


extending rearwardly therefrom. Arms


46




a


,


46




b


each have an aperture


47


therethrough. Arms


46




a


,


46




b


are mounted on upper cross member


42


, with upper cross member


42


extending through the apertures


47


of arms


46




a


,


46




b.






The apertures


17


of arms


46




a


,


46




b


are toleranced such that console


16


can be selectively, rotated to its desired position and is retained in that position until moved again by the user. Console


16


can be rotated


360


degrees about upper cross member


42


. Console


16


can be rotated frontwardly or rearwardly to be selectively placed in folded position shown in FIG.


2


. Console


16


may be comprised of a polymeric material, for example, such as ABS plastic, for example.





FIG. 2

demonstrates that a variety of different members fold on treadmill


10


. Handrail


14


is shown in an operational position in FIG.


1


and in a folded position in FIG.


2


. Console


16


is shown in a folded position in FIG.


2


. Treadbase


12


is shown in an inclined position in FIG.


1


and in a declined position in FIG.


2


.




In one embodiment, in the folded position of

FIG. 2

, the height of treadmill


10


at its highest point is less than about 8 inches. In another embodiment, in the folded position of

FIG. 2

, the height of treadmill


10


at its highest point is less than about 7 inches. In another embodiment, in the folded position of

FIG. 2

, the height of treadmill


10


at its highest point is less than about 6 inches. In another embodiment, in the folded position of

FIG. 2

, the height of treadmill


10


at its highest point is less than about 5 inches.




This size ratio of treadmill


10


is a major advantage of treadmill


10


, allowing it to be moved, e.g., by being slid or rolled under a variety of different pieces of furniture such as beds, desks and other objects or spaces within a home, office or exercise gym.




In the embodiment of

FIGS. 2 and 2



a


, treadmill


10


further comprises rotating castor wheel assembly


50


coupled to frame


30


. Assembly


50


feature wheels


51


which roll about a horizontally oriented axis


52




a


and pivot about a vertically oriented axis


54




a


. For example, in the embodiment of

FIGS. 2 and 2



a


, wheels


51


roll on a horizontally oriented pivot pin


52


and pivot on a vertically oriented pivot pin


54


. Thus, wheels move in a front to back, side to side and diagonal motion. Consequently, treadmill


10


can be rolled in a variety of different directions. This is particularly useful when rolling treadmill


10


under a bed or other piece of furniture. Such castor assemblies


50


may be mounted at one or more corners of treadbase


12


(e.g., the proximal comers or distal comers of treadbase


12


) or in the middle portion of treadbase


12


or in a variety of different positions on treadbase


12


.




Thus, it is possible to glide treadmill


10


using one or more gliders, as shown in

FIG. 1

, or it is possible to roll treadmill


10


using one or more castor assemblies


50


, as shown in FIG.


2


. In another embodiment, treadmill


10


features one or more castor assemblies


50


on one portion of treadmill and one or more gliders on another portion of treadmill


10


. For example, it is possible to mount one or more gliders on a distal portion of treadmill


10


while mounting one more more castor assemblies


50


on a proximal portion of treadmill


10


and vice versa. Optionally, it is possible to mount on or more fixed wheel assemblies


53


that rotate only about a horizontal axis (such as shown in

FIG. 4

) on treadmill


10


(e.g., at distal end


26


) in conjunction with one or more castors


50


and/or gliders.




It can be seen from the folded position of

FIG. 2

that it is convenient for a user to grasp handles


20


(


a


),


20


(


b


) and selectively roll and/or slide treadmill


10


under a bed or under another piece of furniture. This rolling or sliding can occur through the use of castors


50


and/or through the use of gliders on the lower surface of treadbase


12


. Treadbase


10


may be slid or rolled without having to hold treadmill


10


at an angle.




Also as shown in the combined views of

FIGS. 1 and 2

, treadbase


12


selectively moves between a neutral position shown in

FIG. 2

, and an inclined position, shown in FIG.


1


. The inclining mechanism of the present invention will be described in additional detail below.




With reference now to

FIGS. 3 and 4

, a variety of features of treadmill


10


will now be discussed in additional detail including: (i) treadbase frame


30


; (ii) treadbase motor assembly


59


; (iii) treadbase inclining assembly


79


; and (iv) handrail positioning assembly


99


.




Frame


30


comprises first and second side members


70




a


,


70




b


that extend from a proximal end


24


to a distal end


26


of treadbase


12


. Frame


30


further comprises a first cross member


72


extending between first and second side members


70




a


,


70




b


and a second cross member


74


extending between side members


70




a


and


70




b


. Between cross members


72


and


74


extends a first plate


76


and a second plate


78


. First and second plates


76


,


78


thus extend between first and second cross members


72


,


76


. Motor


60


of motor assembly


59


is coupled to first plate


76


and bracket


84


(

FIG. 4

) of inclining assembly


79


is coupled to second plate


78


.




Treadbase motor assembly

comprises: (i) a motor


60


coupled to frame


30


; (ii) a pulley


64


coupled to roller


36




b


; (iii) a drive belt


62


mounted on motor


60


and pulley


64


; (iv) a drive shaft


68


and (v) a flywheel


70


coupled to drive shaft


68


. Actuation of motor


60


rolls roller


36




b


, thereby turning endless belt


38


.




Although flywheel


70


is shown as being coupled to drive shaft


68


, it is possible to orient flywheel


70


into a variety of different positions, as will be discussed in greater detail below. Furthermore, it is possible to employ a variety of different variations from flywheel


70


shown in

FIGS. 3 and 4

. For example, in order to decrease the diameter of a single flywheel, yet preserve the same or more inertia potential, it is possible to employ first and second flywheels (or third, fourth, etc.), which have a smaller diameter than a single flywheel yet collectively provide the same or more inertia potential.




With continued reference now to

FIGS. 3 and 4

, treadmill


10


further comprises treadbase inclining assembly


79


. Treadbase inclining assembly


79


comprises an incline motor

is pivotally coupled at a proximal end


82


thereof to bracket


84


(coupled to plate


78


) and is pivotally coupled at a distal end


86


thereof to bracket


91


of incline mechanism


88


. Bracket

is in an extended position, feet


22




a


,


22




b


are raised.




With continued reference to

FIGS. 3 and 4

, handrail positioning assembly


99


is shown. As mentioned above, handrail


14


is pivotally coupled to frame


30


. A lower cross member


92

to which shock


100


is pivotally coupled.




In one embodiment, shock


100


comprises a gas shock which presses rod


104


outwardly unless a force generated by a user presses rod


104


into barrel


102


. However, shock


100


may also comprise a spring or an elastomeric material which forces rod


104


outwardly unless rod


104


is pressed inwardly by the user. Shock


100


will be discussed in further detail with reference to

FIGS. 5 and 6

. Other linear extending assemblies, such as discussed above, may be employed rather than shock


100


, however, to selectively position handrail


14


.




Shock


100


is shown in a contracted view in FIG.


5


and in an extended view in FIG.


6


. In the contracted position of

FIG. 5

, handrail

is in an upper, operational position, while in

FIG. 6

when shock


100


is extended, handrail


14


is featured in a lower position.




As shown in

FIGS. 5 and 6

, shock


100


further comprises a moveable trigger


116


pivotally coupled to rod


104


. Upon moving trigger


116


against actuation pin


118


coupled to rod


104


, shock


100


is placed in a moveable mode and rod


104


can be moved. Thus, in use, a user actuates trigger


116


by moving trigger


116


against actuation pin


118


, such as through the use of handle


120


coupled to trigger


116


. Depression of pin


118


actuates shock


100


into a moveable mode. When shock


100


is in the movable mode, the user can selectively move handrail


14


from the folded position to the operational position or vice-versa. A user can actuate trigger


116


against actuation pin


118


through the use of handle


120


, another handle, or a variety of different mechanisms.




As one advantage of the use of shock


100


, a user can move handrail to a fully upright position, a folded position, or a variety of different positions therebetween. Shock


100


reliably holds handrail


14


in a desired position until actuation pin


118


is actuated, after which the user can move handrail.




With reference to

FIG. 7

, which features the lower surface of handle


21




a


on the comer of treadbase


12


, glide


33


is coupled to the lower surface of treadbase


12


. Optionally, a glide separate from a handle may be coupled to the treadbase of the present invention.




In the embodiment of

FIG. 8

, a reversible glide member


121


is shown. Glide


121


may be coupled to any portion of the lower surface of treadbase


12


. In one embodiment, first and second glide members


121


are coupled to the distal comers and/or the proximal comers of treadbase


12


. Glide


121


comprises a smooth polymer surface


122




a


for gliding on carpet and a felt surface


122




b


or a surface comprising another soft, deformable material for gliding on wood. Glide


121


may be selectively screwed or bolted to treadbase


12


.




Optionally, however, glide


121


is selectively coupled to glide mount


123


which is affixed to treadbase


12


, the grooves on the sides of glide


121


selectively mating with the ridges in glide mount


123


. Glide


121


may be selectively coupled to glide mount


123


with either side


122




a


or


122




b


down. Glide


121


and mount


123


collectively form a reversible glide assembly. A plurality of such assemblies may be mounted on the lower surfaces of treadbase


12


, such as on the lower proximal and/or distal comers of the treadbase


12


.




Mount


123


may be coupled to the treadbase through a variety of different means, such as through the use of an adhesive, screws, bolts, or other coupling means.




With reference now to

FIGS. 11 through 13

, a variety of different motor assemblies of the present invention may be employed. In the motor assembly of

FIG. 10

, motor


124


is movably coupled to flywheel


120


through the use of a drive belt. Flywheel


120


is coupled to a roller


119


of a treadbase about which a moving belt can be trained. By mounting flywheel


120


separately from motor


120


, as shown in

FIG. 11

, it is possible for flywheel


120


to achieve a faster speed and therefore a greater inertia potential. For example, a gear reduction may be employed between motor


124


and flywheel


120


, such as by having a larger pulley coupled to the motor and a smaller pulley coupled to the flywheel


124


. Thus, by separating motor


124


from flywheel


120


it is possible to achieve a desired amount of inertia potential while nevertheless employing a flywheel


120


having a reduced diameter. Thus, the motor assembly of

FIG. 11

can be employed in the low profile treadmill of the present invention in order to decrease the overall height of the folded treadmill without reducing the inertia potential.




The motor assemblies of

FIGS. 12 and 13

can also be employed in the present invention to decrease the overall height of the folded treadmill without reducing the inertia potential. In the embodiment of

FIG. 12

, motor assembly


130


comprises a motor


134


movably coupled to a roller


136


, such as a treadbase roller


136


, which is movably coupled to a flywheel


132


separate from the roller


136


. This embodiment also allows for a gear reduction which allows flywheel


132


to have increased speed and therefore increased inertia potential.




In another embodiment of dual flywheels shown in

FIG. 13

, motor assembly


140


comprises first and second flywheels


142


,


144


which are mounted on opposing sides of a drive shaft of a motor


146


, the drive shaft being coupled to a treadbase roller


148


. In another embodiment, however, the flywheels are on the same side of the drive shaft. By employing a plurality of flywheels


142


,


144


, each individual flywheel can have a smaller diameter without sacrificing desired inertia potential.




The motor assemblies of

FIGS. 11-13

can thus be employed in the low profile treadmill of the present invention in order to achieve a desired inertia potential without raising the height of the treadmill above a desired height. As another possible mechanism for increasing inertia, it may be possible to employ a controller for controlling the treadbase motor which causes the motor to give short bursts of energy to a flywheel and/or moving belt over a period of time, thereby compensating for any slowing of the belt caused by the movement of the user.




The treadmill


10


of the present invention conveniently fits under a variety of different pieces of furniture or into a variety of different spaces within the home of a user. Thus, the present invention also relates to a system and method for storing a treadmill. The system comprises treadmill


10


or another low profile treadmill disclosed herein. In another embodiment, the system comprises means for raising an item of furniture such as a bed, if such is needed for additional clearance. The means for raising the furniture may comprise castors or blocks or some other object on which the furniture is mounted, if additional height is needed.




In yet another embodiment of the system for storing a treadmill, the item of furniture has a track, frame, or recess which receives the treadmill therein. For example, a bed or chest or drawers may rest on the ground and have a recess therein which receives the treadmill therein. The recess may have track therein on which the treadmill slides or rolls, for example. A door to the furniture may selectively open and close. Thus, the treadmill may be slid, rolled or otherwise placed into the item of furniture, after which a door closes, maintaining the treadmill in the furniture item in an aethestically pleasing condition.




Reference is next made to

FIG. 13

, a block diagram illustrating dataflow between a user interface console


202


(such as console


16


in

FIG. 1

) and a controller across a wireless communication network. In one embodiment of the present invention, the treadmill


10


comprises a wireless data and control network


200


between an electronic user console


202


and a controller


208


. Console


202


can be electrically coupled to the console transceiver


204


via a bidirectional high-speed data bus


210


.




Console transceiver


204


is in wireless communication with the treadbase transceiver


206


via a short-range wireless communication network


212


. The treadbase transceiver


206


is electrically coupled to controller


208


via the high-speed control and feedback bus


214


. In one embodiment, the controller


208


controls the endless belt motor and the inclination motor. Controller


208


can interpret feedback from the exercise device and user interface console


202


to generate control signals for the aforementioned motors, braking systems, monitors and moving parts associated with the treadmill. The received control signals from the exercise device components and user interface console


202


may be compiled into control functions for use by the controller. The controller


208


and treadbase transceiver


206


may be mounted beneath housing


34


, for example.




Through the use of console


202


, the user can control the amount of inclination/declination of treadbase, the speed of the endless belt, and a variety of other features related to exercise apparatus. Other features of the exercise system include the incorporation of various input keypads on the user interface console


202


for setting grade and speed.




User interface console


202


may contain a display device and a control interface. In one embodiment the display device comprises various workout diagnostic panels. The workout diagnostic panels may display workout information on at least one panel of said user interface console


202


. Such workout information may comprise at least one of: speed of endless belt, percentage of workout completion, distance traveled, relative workout segment difficulty, remaining workout segment length, selected workout routine, and information about the workout profile, for example. The control interface is an example of an interface means for receiving workout related control inputs, such as a keypad.




In another embodiment of a user console, the display device of the console is located remotely from the exercise apparatus. For example, the display device may comprise a wall mounted or hand held display. Control interface on the user console


202


may comprise several individual adjustment keypads for interfacing with the selectively adjustable exercise apparatus. For example, a grade adjustment keypad may allow the user to select a desired grade of an operable member of the selectively adjustable exercise apparatus through quick touch keys with pre-set percentage grade values and automatically adjust the device to the selected level.




Specifically, grade adjustment keypad may have pre-set percentage grade keys for—5%, 0%, 10%, 20%, 30%, 40%, 50%, and 60% grade, for example, although a variety of different grades are available. Upon reception of user input from user interface console


202


, controller


208


may increase the grade or resistance depending on the attached exercise device. Similarly, inclination and declination interface buttons, included in the grade adjustment keypad, may allow a user to increase or decrease the grade in pre-set grade intervals, for example 1% grade intervals.




A start interface button on the user interface console


202


allows a user to begin the workout once selected or the previous workout segment has been restored. A stop/pause interface button allows a user to stop or pause the workout and save the location of the user's workout for future use. A speed adjustment keypad on the user interface console


202


allows the user to adjust the speed of the particular exercise device. Specifically, the speed adjustment keypad may have preset keys for 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0 and 6.0 mph, for example. In addition to the aforementioned preset speed values, increase and decrease buttons increase or decrease the selectively adjustable exercise apparatus operable member (endless belt) speed in 1/10


th


intervals. In one treadmill configuration, the treadbase will gradually increase the belt speed according to the inputs from the user interface console


202


.




An incremental adjustment keypad contains an increment and decrement input keys as well as a final enter input key. One embodiment allows a user to input their age through this keypad so that the exercise system can customize a workout and monitoring system. Another embodiment allows a user to use this keypad to enter one or more of the following workout variables: the exerciser's age, length of workout segment, distance of workout segment, maximum speed of workout segment, maximum pulse, target heart rate, maximum grade, calories to be burned, and maximum heart rate. These keys may also be used along with the workout panel to specifically select a workout segment, making adjustments in the present workout profile, or even to select different workouts.




Once the user has selected the desired control settings on the user interface console


202


, the information is transmitted along the high-speed data bus


210


to console transceiver


204


. Console transceiver


204


is in wireless communication with treadbase transceiver


206


via a short-range wireless communication network


212


. While long-range wireless standards such as cellular and digital may be available and well defined, the near proximity use of near and even co-located console


202


and controller


208


devices wants for the use of a short-range wireless standard. One such short-range wireless standard that is in the process of being embraced by the electronics industry is preliminarily known by the name of “Bluetooth.”




Bluetooth, which is only one example of a short-range wireless standard, is actually a combination of specialized computer chips and software. Bluetooth is the codename for a technology specification for small form factor, low-cost, short-range radio links between mobile PCs, mobile phones and other portable devices. These short-range wireless standards, such as Bluetooth, use radio waves to transmit information, link gadgets as far as 30 feet away, and even those devices in different rooms that are not in the line of sight. Bluetooth, for example, also offers speedy transmission of up to one megabyte per second, over 17 times as fast as a typical modem. These standards enable users to connect a wide range of digital, computing, and telecommunications devices easily and simply, without the need to buy, carry, or connect cables. They deliver opportunities for rapid ad hoc connections, and the possibility of automatic, unconscious, connections between devices. They may virtually eliminate the need to purchase additional or proprietary cabling to connect individual devices. Because these standards can be used for a variety of purposes, they will also potentially replace multiple cable connections via a single radio link. It is important for a communication center to be short-range wireless capable, in view of this potential. Unfortunately, short-range wireless interface chips can add tens of dollars to the price of a gadget, which is expensive for low-cost low-margin devices like a computer mouse, a coffee pot or even a mobile phone, which manufacturers often give away as part of service deals. In addition, Bluetooth's short-range wireless standards approximate 30-foot range is considered too short to network all home electronics, but is perfect for the wireless communication needed in the exercise device between console


202


, controller


208


, and other wireless peripherals, such as a heart monitor or iFit.com connection. Presently, the Bluetooth connection in accordance with short-range wireless specifications will have an operational range of around ten meters from the transceiver.




Other acceptable wireless protocols for the short-range wireless communication network


212


include RF, IR, 802.11 RF, 900 MHz, and other acceptable short-range wireless protocols. In short, the wireless communication network may include transmitters and receivers capable of interpreting radio frequency transmissions, optical transmissions, electromagnetic waves, or other wireless transmission medium. The short-range wireless functionality of the short-range wireless communication network


212


also allows the exercise device to expand through Bluetooth, 802.11 RF, Infared, RF, or other short-range wireless capable peripheral devices.




The controller


208


may be a microcontroller, a central processing unit (CPU), a state machine, a programmable logic array, or network of logical gates, ASIC processor, software-based controller, a combination of these components, or a variety of other controllers. Each of these controller examples are examples of processor means for electronically computing operational information based at least in part on control inputs received from an interface means. The controller receives feedback signals from the treadmill and a workout profile and converts the feedback signals into control signals for the display device and exercise apparatus. Data for the controller may be stored in registers or memory modules. In one embodiment, the controller includes a temporary storage media for use with the display device on the user interface console. The temporary storage media provides a buffer for each of the displayed values, such as speed of endless belt, pulse, heart rate, average pulse and heart rate, target heart rate, calories burned and target calories to burn during workout session, length of workout session, and other displayed values. This multi-buffer system allows for the simple control and rapid refresh of the user workout data.
