Description
RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 09/496,560, Filed Feb. 2, 2000, entitled
"System and Method for Selective Adjustment of Exercise Apparatus"
to Ashby, et al, which is incorporated herein in its entirety by
reference.
BACKGROUND OF THE INVENTION
[0002] 1. The Field of the Invention
[0003] The invention is in the field of electronic controllers for
exercise equipment. More specifically, this invention relates to a
method and system for selective adjustment of an exercise apparatus
to simulate movement along a desired pathway.
[0004] 2. The Relevant Technology
[0005] 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.
Furthermore, in modem urban society, it has become more and more
difficult for the average individual to experience the exhilaration
of exercising in nature. To compensate for this difficulty,
athletic sports gyms and exercise facilities featuring treadmills,
bicycles or exercise bicycles, weights, and stair stepper machines,
have been developed in great abundance.
[0006] Climbing devices have also become very popular in recent
years. Climbing requires a user to raise the user's knees in
continual, strenuous strides. Climbing typically requires more
exertion than mere walking on a flat surface. Consequently, the
exercise of climbing can provide a more intense, challenging
workout. Climbing exercise apparatuses typically feature an endless
moving assembly, which is set on a significant angle and has a
series of foot supports or steps. This configuration allows the
exerciser to simulate the movements of climbing, walking, or
running up a steep incline. Angled, moving staircase-type devices
are typical examples of such climbing apparatuses.
[0007] Unfortunately, typical climbing devices within the art are
tall and often require more ceiling height than is available in an
exerciser's home. Thus, such climbing devices generally require a
gym or warehouse, or at least a vaulted ceiling. Treadmill devices
that fit into a user's home generally incline from a neutral
position to an inclined position, then decline back to the neutral
position. However, typical treadmill devices fail to adequately
provide a user with the kind of terrain experience encountered when
ambulating over rocky, rough, and natural terrain. For example, a
hiker traversing a hiking trail typically exhibits greater lateral
movement than most treadmill belts presently allow. Furthermore,
beginning at around a 15% grade, a hiker exercising on a treadmill
can start producing more energy than is necessary to drive the
treadmill belt, such that a braking system is desirably employed.
These structural, systematic requirements are presently not
considered in the design of modern treadmills.
[0008] What is needed is a controller on an exercise apparatus that
simulates the dynamics of natural terrain with its accompanying
slopes and inclines and can fit into a user's home or another
location with a limited ceiling height. Unfortunately, controllers
presently associated with these exercise devices are only capable
of creating an artificial time based environment. Generally, these
exercise devices use an indicator to demonstrate the increase in
workout difficulty as a treadmill increases its inclination or a
stair stepper becomes more difficult to climb. These devices are
exclusively time based, meaning that no matter how slowly an
individual is walking, after a certain amount of time, an
artificial hill displayed will pass. Unfortunately, time based
regulation does not accurately simulate the environment that exists
in a real hike or a real walk, depriving the individual of the
substantial health benefits associated with a cardiovascular
workout based substantially on a natural setting.
[0009] Exercise devices that utilize artificial mountain profiles
typically create mountains of speed or of incline. Usually, these
artificial profiles are time based workouts, where at a
preprogrammed time in the workout, the exercise apparatus moves a
little faster or increases the resistance, and then during the next
workout segment the device alters its operating parameters again.
Eventually, the device works its way up to a maximum speed, maximum
incline, or maximum workout. Accordingly, the artificial profile
adjusts the exercise apparatus so that the next segment becomes
less difficult or more difficult by changing the resistance,
inclination, or speed. As such, the typical exercise device goes
through pre-set profiles. However, the artificial mountain or hill
segments are simply time-based alterations of resistance, speed or
inclination. Thus, typical workouts lack the natural diversity
provided by a mountain trail.
[0010] The natural diversity provided by mountain trails yields
additional incentives for a user to complete a workout.
Representative exercise devices lack these incentives when their
workouts are based purely on artificial workout profiles.
[0011] Finally, users of existing climbing exercise devices are
increasingly faced with the difficulty of interpreting multiple
monitoring panels with a single glance during the workout,
resulting in sensory overload for the user. Most controllers
contain separate indicators for distance traveled, vertical feet
traversed, remaining workout length, and relative grade or incline
adjustments to be made. It is difficult for a user to interpret and
understand all of these gauges with one glance.
SUMMARY OF THE INVENTION
[0012] It is therefore an object of this invention to provide a
method and system that electronically simulates a mountain
hike.
[0013] It is another object of this invention to provide a method
and system for converting a topographical map to an actual exercise
workout for use with an exercise device that can vary between a
variety of grades.
[0014] It is a further object of the invention to allow the user
direct adjustment control of grade and speed, as well as tracking
vertical feet hiked and the overall distance and speed.
[0015] It is a further object of the invention to provide exercise
devices such as hiking apparatuses, climbers, treadmills, exercise
bicycles, skiers, aerobic ellipticals, rowing devices, steppers and
other devices that can simulate mountain trails, mountain streams,
or rough terrain through an adjustment in resistance, incline, or
speed.
[0016] It is another object of the invention to provide a
controller which controls a workout that is both time and distance
based, thereby allowing an individual to hike at their own pace and
ensuring that they adequately follow a realistic mountain trail
length.
[0017] It is another object of the invention to provide a single
glance panel containing graphic representations because the user is
only be minimally distracted from a workout.
[0018] It is another object of the invention to provide a carefully
designed graphical representation panel allowing the user to obtain
all of the important information with one glance.
[0019] These and other objects of the invention, as will be
apparent herein, are accomplished by generating a mountain exercise
profile having trail workout segments that are digitally coded to
enable a selectively adjustable exercise device. A selectively
adjustable exercise system comprises a virtual trail system for use
on a selectively adjustable exercise apparatus.
[0020] Aside from being electrically coupled to the selectively
adjustable exercise device and a display device, a controller of
the virtual trail system operates according to software based
workout profiles. The software interprets feedback from the
exercise device and a user interface console to generate control
signals for motors, electronic braking systems, and user monitors
associated with the virtual trail system. The control signals for
the exercise device components and display device panels are
compiled into workout profiles for use by the controller. Other
features of the exercise system include the incorporation of direct
adjustment keypads on the user interface console for grade and
speed settings. These keypads are primarily used when the system is
not recalling a preprogrammed workout routine or hiking trail and
is under manual control.
[0021] These and other objects and features of the present
invention will be more fully apparent from the following
description and appended claims, or may be learned by the practice
of the invention as set forth herein.
BRIEF DESCRIPTION OF THE DRAWINGS
[0022] In order that the manner in which the above recited and
other advantages and objects of the invention are obtained, a more
particular description of the invention briefly described above
will be rendered by reference to specific embodiments thereof,
which are illustrated, in the appended drawings. Understanding that
these drawings depict only typical embodiments of the invention and
are not therefore to be considered to be limiting of its scope, the
invention will be described and explained with additional
specificity and detail through the use of the accompanying drawings
in which:
[0023] FIG. 1 illustrates a selectively inclining exercise
system.
[0024] FIG. 2 is a motivational display device configured with
three workout profiles created from actual trails in the Grand
Teton mountain range and terrain.
[0025] FIG. 3 is a control diagram of an interface console for a
virtual trail system with trail workout incentives for an exercise
system.
[0026] FIG. 4 is a block diagram illustrating encoding of a
mountain trail, creating a workout profile, and operating a
previously encoded hike.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] The invention is described below by using diagrams to
illustrate either the structure or processing of embodiments used
to implement the systems and methods of the present invention.
Using the diagrams in this manner to present the invention should
not be construed as limiting of its scope. The present invention
contemplates both methods and systems for selective adjustment of
exercise equipment.
[0028] One embodiment of a virtual trail system of the present
invention comprises: (i) an interface means for receiving workout
related control inputs from the user of the exercise equipment;
(ii) processor means for electronically computing operational
information based at least on part on control inputs received from
the interface means; (iii) feedback means for conveying information
concerning the amount of exercise performed by the user to the
processor means; (iv) indicator means for displaying workout
information to the user adapted for indexing travel along the
length of a workout trail from segment checkpoint to segment
checkpoint until the end of the trail; and, preferably, (v) control
means associated with the processor means for causing the indicator
means in response to information from the feedback means to travel
along the workout trail at a rate proportional to the rate of which
exercise is performed by the user.
[0029] This virtual trail system may be used in a wide variety of
selectively adjustable exercise equipment. For example, in one
embodiment as depicted in FIG. 1, the virtual trail system is
associated with a hiking exercise apparatus. The virtual trail
system may also be employed on variety of other hiking exercise
apparatuses, such as those identified in U.S. patent application to
Cutler, et al entitled "Hiking Exercise Apparatus," filed on Feb.
2, 2000, which is incorporated herein in its entirety by
reference.
[0030] In addition to treadmills, alternative embodiments include
associating the virtual trail system with an exercise cycle, an
elliptical aerobic apparatus, a stair stepper, a skiing device,
rowing equipment, and other exercise devices, can also simulate
mountain trails, mountain streams, or rough terrain. Each of these
exercise equipment embodiments would require unique components as
previously designated to provide the necessary adjustment in
resistance, incline, or speed. However, many of the embodiments
contain considerable crossover for their respective
applications.
[0031] For example, an exercise cycle can very easily use a
mountain biking trail to create a similar experience as a hiker
might experience on a treadmill or stair stepper. One difference in
the hiker and bicycle embodiments would be that the exercise cycle
can either increase the resistance or physically move the exercise
cycle in an up and down fashion.
[0032] An embodiment based on a skiing device can use mountain
cross-country ski trails and either adjust actual grade or alter
the resistance. A rowing device can simulate mountain streams or
rivers by adjusting rowing resistance or restricting the rowing
action.
[0033] The mountain exercise profile may use topical maps, GPS
coordinates, or portable monitors to design the actual exercise
program. A trail workout designer can plot a trail over a mountain
area on a topographical map and a profile of the incline changes
over the terrain will be created. Workout segments can be created
which average the slope change for that distance, resulting in
multiple grade changes according to the trail segment.
[0034] In FIG. 2, examples of such workout segments are designated
as the trail between the alphabetical markers on each trail. An
alternative embodiment allows for workout segments to be subdivided
for multiple grade adjustments. These workout segments are combined
into a workout profile. Following a review of the workout profile
by a trainer, the trail workout designer will be able to identify
the density of the trails and alter the workout segment lengths in
order to fit a similar trail workout on to the specified exercise
device. Specifically, the trail workout designer creates variable
segment lengths that best compare to the natural hike, including
gradual incline segments, short steep segments, and short negative
grade segments. A trail workout designer can also use GPS
coordinates in conjunction with a master topographical map to
create a successful workout trail. Midway or rest points may also
be incorporated into a workout trail at the end of a workout
segment.
[0035] Monitor devices enable a hiker to carry the monitor on an
actual hike and record the distance and inclination walked by the
user, and then apply that particular hike to the exercise machine
software. This allows the user to exercise on weather prohibitive
days (rain, snow, or extreme heat) in which the weather does not
allow a user to go outside. The user can hike the same virtual path
that they normally would take. Portable monitors also allow a user
to record their favorite workout by walking the trail with the
monitor on. Upon electrically coupling the monitor to the exercise
system, the monitored activity can be downloaded to the virtual
trail system attached to the exercise apparatus. The virtual trail
system converts the monitored information into a workout for the
exercise device. This provides the user with some exciting new
benefits. For example, if it rains or snows, a user can follow
their favorite hike or mountain bike trail on an exercise bike,
even if there is too much rain or snow on the ground.
[0036] There are multiple methods of coding the hiking trail or
hiking profile. The most prevalent and preferred embodiment is a
translation of a topographical map into a workout and onto a hard
coded copy of a mountain. The hard coded copy may be stored on an
ASIC chip, a programmable ROM, a magnetic disk, PCMCIA card, or
Compaq flash card. More specifically, the software is stored in a
memory module that may be upgraded with new mountain trails or
workouts. This memory module may be constructed from at least one
of programmable ROM, Dynamic Memory, EEPROM, flash bios, PCMCIA
cards, CD-ROM, RAM, magnetic storage disks, and Compaq flash cards.
The exercise system may also provide the memory module through an
electrical connection to a general-purpose computer. It may also be
downloaded from an Internet site such as www.iFit.com across a
communication line connection, for example via the PSTN, DSL,
G-Lite, cable modem, wireless or other high-speed data connection.
Particularly as the cost of wireless technology drops, a wireless
connection to exercise profile sites such as iFit.com is also
foreseeable.
[0037] Hiking profile coding also provides the additional advantage
of recording a hike that a user might not be able to accomplish in
one exercise session, especially if it is an all-day or multiple
day hike. Since the average workout session lasts between about 15
minutes and 1 hour, a user would not complete longer hikes without
positional cursor storage. However, the virtual trail system
optionally saves the location of the user, so that upon their
return to the exercise system, they are able to begin their workout
where they last left off. Thus, a daylong hike of eight hours might
take an individual one or two weeks to complete at thirty-minute
intervals. However, the individual would have covered the same
exact terrain as was covered in the original walk. In this sense,
the exercise system is able to provide a user with long-term
physical goals and related incentives inspiring follow-up workout
sessions. This natural variety and follow-up incentive are
important keys to keeping the user on a regular exercise plan.
[0038] One of the features in this invention is the interface
between the display device, the controller, the adjustable exercise
device, and possibly additional software. In a preferred embodiment
the software is upgradeable and Internet capable. The display
device is conveniently located on the exercise device or is
optionally separate therefrom, such as a wall mounted or hand-held
display, and provides indicator signals. Thus, the display device
may be physically located on the exercise device, but may be
separate therefrom in another embodiment. The controller creates
codes for the display device and adjustment codes for the exercise
device. The exercise device is preferably adjustable. The exercise
device may act as a flat treadmill, hiker, or stepper, for example.
What distinguishes this exercise system from other systems is that
the user has direct control of the speed and grade. In some
embodiments the system may control speed and grade during workout
routines. The present invention differs from other devices, which
feature time-based workouts, whereas this device uses
distance-based workouts.
[0039] The display device is an example of an indicator means for
displaying workout information to the user and should be positioned
so that a user may easily interface with the controller and observe
their progress in several categories of performance. An adjustable
attachment is preferred so that users of varying sizes will have
equivalent visual access. In considering construction factors such
as reliability, cost, and performance, a liquid crystal display
(LCD) provides the greatest flexibility for the display device.
Other acceptable indicator means include LED displays, video
monitors, color LCD, and flat LCD video screens. Each of these
visual indicator means can be varied using colors, brightness, or
synchronized pulses to represent various status conditions.
Typically, the indicator means is a visual indicator, but auditory
and tactile indicators may also be used as indicator means. Audio
indicators may generate a full spectrum of audible noises,
including music, chirping, beeping, continuous tone, or a specific
audible message. Tactile indicators include vibration, texture
alteration, electric tingle, generation of specific Braille
characters, or the creation of a temperature variation.
[0040] FIG. 2 provides an example of a preferred embodiment of
implementing the invention. This should not be seen as a
limitation, however, on the arrangement or construction of the
exercise apparatus. For example, in one embodiment, an LCD is
employed to display clips from the actual hike or workout trail,
instead of a topographical display screen.
[0041] The controller 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
the interface means. The controller receives feedback signals from
the exercise apparatus and the 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. The controller makes adjustments to
the exercise device simulating mountainous terrain. In one
embodiment, the controller includes a temporary storage media for
use with the display means. The temporary storage media provides a
buffer for each of the displayed values, such as user age, maximum
pulse and 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.
[0042] With reference now to FIG. 1, a selectively inclining and
declining climbing exercise apparatus 10 of the present invention
is shown. Exercise apparatus 10 supports a user ambulating thereon.
Selectively inclining and declining apparatus 10 comprises a
support base 12, a treadbase 14, and a handrail assembly 16. A
variety of other examples of selectively inclining and declining
hiking exercise apparatuses such as apparatus 10 to be employed in
the present invention are disclosed in U.S. patent application to
Cutler, et al entitled "Hiking Exercise Apparatus," filed on Feb.
2, 2000, which is incorporated herein in its entirety by
reference.
[0043] In a neutral position, treadbase 14 is parallel to a support
surface. Treadbase 14 is capable of inclining to extreme angles,
such that a distal end is high above the neutral position. This
enables an exerciser to simulate a hiking motion that requires the
user to continually lift the user's knees in an upward,
outstretched manner. Treadbase 14 also declines such that a distal
end thereof drops below the neutral position. Typical hikes in the
mountains, for example, involve inclines and declines as well as
flat surfaces. Thus, apparatus 10 is able to more closely simulate
a typical mountainous terrain. A hiker traversing a hiking trail
typically exhibits substantial lateral movement. Thus, treadbase 14
preferably has an aspect ratio featuring a wide treadbase 14.
Examples of such aspect ratios are disclosed in the U.S. patent
application to Cutler, et al entitled "Hiking Exercise Apparatus,"
filed on Feb. 2, 2000, which is incorporated herein in its entirety
by reference as indicated above.
[0044] The coupling of treadbase 14 and the positioning of handrail
assembly 16 may occur in a variety of different positions depending
upon the embodiment. In the embodiment of FIG. 1, treadbase 14 is
pivotally coupled at the proximal end thereof to the proximal end
of support base 12. Support base 12 rests on a support surface. In
the embodiment of FIG. 1, treadbase 14 comprises a treadbase frame,
first and second rollers (only one roller shown) on opposite ends
of the treadbase frame, and an endless belt movably mounted on the
rollers.
[0045] In one embodiment, treadbase 14 is selectively moved into a
position having a grade of about -30% (declined) with respect to
the neutral position to about 90 degrees (inclined) with respect to
the neutral position, preferably having a grade of about -20%
(declined) with respect to the neutral position to about 60 degrees
(inclined) with respect to the neutral position, more preferably,
having a grade of about -10% with respect to the neutral position
to about 100% (45 degrees) with respect to the neutral position,
more preferably, having a grade of about -10% with respect to the
neutral position to about 60% with respect to the neutral position.
In another embodiment, treadbase 14 is selectively moved into a
position having a grade of about -5% with respect to the neutral
position to about 50% or 60% with respect to the neutral
position.
[0046] However, these ranges are generally more of a physical
limitation than an electronic limitation as the console 200 for the
exercise apparatus can be configured in one embodiment to provide
negative 360 degrees to positive 360-degree rotation.
[0047] By moving between these extreme ranges, an exerciser is able
to simulate a hike through a variety of different slopes and
angles. The virtual trail system includes an electronic console
200. Console 200 is electrically coupled to the inclination motor
18. The virtual trail system controls the amount of
inclination/declination during each segment. Through the use of
console 200, the user can control the amount of
inclination/declination of treadbase 14, the speed of the endless
belt and a variety of other features related to apparatus 10.
[0048] In one embodiment, the exercise system includes braking
means for electronically slowing the speed of the operable member,
such as an electronic braking system. When the exercise device
exceeds a variable incline level, established by the weight of the
user and the inherent resistance of the system, the force exerted
on the motor of the exercise apparatus exceeds the force generated
by the motor to drive the operable member of the apparatus and the
electronic braking system should be activated. For hiking devices,
this variable incline level can occur at approximately 15%,
depending on the inherent system resistance and the forces exerted
by the user. At this grade, the energy generated by the user
ambulating on the exercise device exceeds the power required to
drive the motor on the operable member. At inclines above about 15%
the power generated by the virtual trail system exceeds
approximately 100 Watts, requiring the braking means to dissipate
the excess power generated by the virtual trail system. In one
embodiment, the braking means of the present invention dissipates
excess power generated by the virtual trail system when the power
generated by the system exceeds approximately 100 Watts to
approximately 700 Watts. Certain users ambulating at extreme
incline settings generate excess power in the range of 500 to 700
Watts for example, depending on user and treadmill
specifications.
[0049] Therefore in the preferred embodiment, the presence of
excess power activates the electronic braking system, which
dissipates the excess power and maintains the appropriate speed of
the operable member. One method of reducing this excess power is
through a feedback loop connected to the power supply for the
motor, in essence reducing the power available to the motor and
slowing the belt. Another method senses the presence of excess
power and activates the electronic braking system by closing a
switch between the motor and a power resistor, such as a heating
coil resistor. This method effectively allows the motor to generate
more power, but absorbs excess power via the power resistor in the
required range of about 100 to about 700 watts, e.g. about 500 to
about 700 watts. In one embodiment, a heating coil is provided to
provide inexpensive power dissipation. However, care must be taken
to disperse the heat generated by high energy levels.
[0050] In the preferred embodiment, a device cutoff system within
the electronic braking system activates a forced ventilation system
when heat levels begin to exceed pre-established operating ranges
and in extreme cases completely cutoff the treadmill system until
the detected heat levels returned to safe operating ranges.
Generally, the power resistor circuit employed in the exercise
device is system specific, and designed to dissipate excess power
generated by the motor during to prolonged use at extreme inclines.
Once the power is dissipated, the virtual trail system will open
the circuit between the motor and the power resistor. In this
manner the virtual trail system is able to maintain a constant
speed for the operable member at high speed and high inclination
settings.
[0051] Other examples of braking systems are disclosed in the U.S.
patent application "Hiking Exerciser Apparatus," incorporated
herein by reference.
[0052] As mentioned above, the aspect ratio, i.e., the length and
width of treadbase 14 is such that climbing apparatus 10 simulates
a climbing motion and allows the user the lateral movement
associated therewith, yet has a minimal footprint and can be
conveniently used and stored in a home or exercise gym.
[0053] Handrail assembly 16 will now be discussed in additional
detail with reference to FIG. 1. The handrail assembly 16 of the
present invention can be comprised of a variety of different
members and have a variety of different configurations, such as
those featured presently in the art. Handrail assembly 16 of FIG. 1
is coupled to the treadbase 14 such that the position of handrail
assembly 16 adjusts automatically throughout the range of motion of
treadbase 14. Thus, handrail assembly 16 is useful to the exerciser
throughout the range of motion. Handrail assembly 16 has an
operative, useful position regardless of whether treadbase 14 is in
an inclined, declined, or neutral position. However, a fixed
handrail assembly may also be employed which does not provide such
adjustment. Handrail assembly 16 may also contain components of the
feedback circuitry for monitoring the users heart rate through the
physical connection created by the user's hold on the handrail
assembly 16.
[0054] In the embodiment of FIG. 1, inclination motor 18, which
controls the amount of inclination/declination during each segment,
is part of handrail assembly 16. Handrail assembly 16 is pivotally
coupled to treadbase 14 and to support base 12. Motor 18
selectively inclines and declines assembly 16, thereby selectively
inclining and declining treadbase 14. However, in other
embodiments, such as described in U.S. patent application to
Cutler, et al entitled "Hiking Exercise Apparatus," filed on Feb.
2, 2000, which is incorporated herein in its entirety by reference
as indicated above, an extension motor or other means for
selectively moving the treadbase is directly coupled between the
treadbase and the support base or coupled thereto in a variety of
other fashions.
[0055] With reference to FIG. 2, a user console 200 contains a
display device 202 and a control interface 218. Display device 202
is an example of an indicator means. Control interface 218 is an
example of an interface means for receiving workout related control
inputs. Display device 202 contains various workout diagnostic
panels. 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.
[0056] Trail workout panel 204 displays trail workout information
on one panel of said user interface console 200, the trail workout
information comprising at least one of: percentage of trail workout
completion, relative trail elevation, distance traveled, vertical
distance traveled, workout segment difficulty, remaining segment
length, selected trail workout routine, and topographical
information concerning the trail workout profile. In one
embodiment, each of these features are present. This single glance
panel provides an optimal amount of workout information to the user
without distracting the user from the workout. Grade program
control panel 206 includes an incline display representing the
inclination of the treadmill or exercise device in degrees or grade
percentage. In the embodiment of FIG. 2, the incline, terrain, or
hill varies from -5% to 60% grades or -5 to 32 degrees of angular
movement on the grade program control panel 206. The grade program
control panel 206 may contain a terrain or hill display array that
is constructed from a selectively illuminated LED display
array.
[0057] The virtual trail system causes the exercise device to
incline the treadbase grade or increase resistance so as to
correspond to the hills displayed on the grade program control
terrain display. In this manner, the user is provided with a
short-term display of upcoming and/or current terrain. The grade
program control panel 206 also contains a manual control indicator
to signify that the user is establishing grade settings. Grade
program control panel 206 further comprises a data field shown in
FIG. 2 to have 21 columns with 10 indicators in each column.
Although primarily configured to indicate short-term grade
settings, this array of indicators may also be used to indicate any
number of different parameters. For example, the grade changes can
be attached to indicate speed changes. The preferred display panel
configuration takes grade changes or resistance changes that are
pending during the workout program and shows the changes
graphically. In FIG. 2, the second to bottom horizontal row of the
grade program control panel 206 would be regarded as zero, with the
number of vertical blocks being illuminated to show the relative
incline, grade, speed, or other value depicted. This array can be
expanded to include more accuracy concerning the grade or angled
inclination. As the capabilities of the exercise equipment
processor increase, the display scale can be shifted.
[0058] A hike exertion panel 208 provides a single row of colored
indicator LEDs summarizing the workout stress level placed upon the
user. The hike exertion panel 208 divides the colored indicator
LEDs into four subcategories: warm-up/cool-down, moderate hike,
challenging hike, and Extreme hike. The subcategories are either
based upon preprogrammed values for grade level independent of the
user's response to the system and speed level or the indicator
panel 208 can be a compilation and summarization of indicator
panels 204, 206, 210, 212, 214, and 216 adapted to each user. In
this second configuration, the hike exertion panel 208 becomes a
single look pacing indicator panel considering age, heart rate,
speed, grade, pace, and hike ranking. As such the hike exertion
panel 208 is at least indirectly connected to the feedback
circuitry, which measures the performance of the exercise equipment
and/or the user.
[0059] The heart rate training zone indicator panel 210 selectively
indicates age, heart rate and percentage of maximum heart rate of
the user that is exercising. Training zone indicators show a user
whether the current workout is proceeding above, below, or at the
target heart rate for the user's age. The pulse sensor is activated
after the user enters their age before the workout begins using the
incremental adjustment keypad 240. In the preferred embodiment, the
virtual trail system will remember a user's vitals after they renew
a previous workout. Heart rate training zone indicator 210 is an
extremely useful feature as it allows the trail workout to be
personalized for each user, assuring that a maximum cardiovascular
workout is obtained. Optional safety features in the virtual trail
system include a monitor of a user's heart rate that reduces the
stress or exertion levels imposed upon the user when the heart rate
exceeds the target value. The stress level may be increased for a
user whose heart rate is at or below the target level. These heart
rate signals are received at least indirectly from the user
feedback circuitry, part of the feedback means, which may collect
information from a heart monitor worn, by the user or a heart
monitor placed in handrail assembly 16.
[0060] Time and distance indicator panel 212 indicate the distance
traveled or the segment time required for the user to travel
between exercise workout segments, or the overall time required for
the trail workout. Indicator panel 214 selectively provides the
vertical feet traveled, the calories burned, the percentage of
grade, and the maximum percentage. The time and distance indicator
panel 212 and the indicator panel 214 are at least indirectly
attached to feedback circuitry connected to the exercise device.
Speed indicator panel 216 provides the speed presently traveled on
the exercise device, or the maximum speed attained during the
exercise period. The speed indicator panel 216 is indirectly
attached to the feedback circuitry on the exercise device and more
specifically to circuitry connected to the electronic braking
system used to regulate the belt speed on the treadbase.
[0061] Control interface 218 comprises several individual
adjustment keypads for interfacing with the selectively adjustable
exercise apparatus. Direct grade adjustment keypad 220 allows 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, direct grade adjustment
keypad 220 has pre-set percentage grade keys for -5%, 0%, 10%, 20%,
30%, 40%, 50%, and 60%, for example, although a variety of
different grades are available. The grade program controller may
increase the grade or residence depending on the exercise device
attached to the grade program controller. For example, a treadmill
can increase the inclination of the treadbase to the desired grade.
A bicycle exercise device can increase the resistance such that a
comparable grade is represented. A skiing device can elevate the
slope of the surface being skied upon. Similar grade or resistance
adjustments can be made for other exercise devices. Inclination and
declination interface buttons are also included in the direct grade
adjustment keypad 220. These keys allow a user to increase or
decrease the grade in 1% grade intervals, for example.
[0062] Start interface button 224 allows a user to begin the trail
workout once the trail has been selected or the previous segment
has been restored. Stop/Pause interface button 226 allows a user to
stop or pause the workout and save the location of the user's last
position on the trail for future use or allows the user to recover
from overexertion. In one embodiment, Stop/Pause interface button
226 is electronically connected to an electronic braking system
that prevents a user from driving the treadbase faster than the
speed driven by a motor, but also for slowing the treadbase down to
a stopped position so that the user won't fall of the
treadbase.
[0063] As mentioned above, beginning at around a 15% grade, a hiker
exercising on a treadmill may start producing more energy than is
necessary to drive the treadmill belt. Thus the braking system of
the present invention is useful at inclines such as in excess of
about 15% grade and is particularly useful at high inclines, such
as in excess of about 25% grade. The electronic braking system is
electronically connected to the feedback means for calculating the
actual belt speed of a given treadbase. The feedback means sends
this information to the processor means for further adjustment of
the treadbase to optimize to overall performance of the climbing
exercise device.
[0064] Power indicators 228 show whether the proper activation key
has been provided to the selectively adjustable exercise apparatus.
In one embodiment, the activation key is a physical electronic key
that stores the users workout information. Other embodiments may
require an electronic key or password be typed in so that the
workout information can be restored from a user database. Another
embodiment uses a physical key as a safety measure to prevent
unauthorized use of the trail exercise apparatus.
[0065] Direct speed adjustment keypad 222 allows the user to adjust
the speed of the particular exercise device. Specifically, direct
speed adjustment keypad 222 has keys for 0.5, 1.0, 1.5, 2.0, 3.0,
4.0, 5.0 and 6.0 mph. In addition to the aforementioned preset
speed values, increase and decrease buttons increase or decrease
the selectively adjustable exercise apparatus operable member speed
in 1/10.sup.th intervals. In the preferred treadmill configuration,
the treadbase will gradually increase the belt speed according to
the inputs from the user interface console 200.
[0066] Incremental adjustment keypad 240 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 virtual trail 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, vertical feet 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 trail workout panel to specifically select a workout
segment for making adjustments in the present workout profile or
even to select different trails. For example, the virtual trail
system of FIG. 2 displays the Grand Teton trails and it is
foreseeable that various popular mountain recreation areas like Mt.
McKinley, Mt. Rainer, Mt. Hood, the Swiss Alps, the Ozark or
Allegheny Mountains, or Mt. Everest hiking layouts can be imposed
in the trail workout panel 204 using the incremental adjustment
keypad 240.
[0067] The total input key 242 changes the display panels 210, 212,
214 and 216 to display their total or maximum changes. Thus an
individual is enabled to see the total distance traveled, the total
time of the workout, the total vertical feet traveled, the total
calories burned, the average grade, and the maximum percentage. The
average speed can also be indicated through the total button. In
one embodiment, the results displayed when total input key 242 is
pressed, are computed using registers which increment the values
for the time and distance, vertical feet, and calories burned
during the workout profile at variable rates depending on the
amount of exercise and the speed of exercise being performed by the
user. These figures are dictated by the device parameters. For
example, the distance traveled in the preferred treadmill
embodiment is based upon the speed of the belt on the tread base,
and the distance covered by a user running upon such a base. The
total calories burned would be based on the angle or the grade of
the tread base and the speed of the tread base. Another embodiment
includes the monitored heart rate of the individual working on the
treadmill as a variable to compute the calories burned.
[0068] The select trail keypad 238 allows a user to choose a
moderate, challenging, or extreme trail for their workout. In the
preferred embodiment provided in FIG. 2, these trails are
represented by the Teepee Glacier trail 234 as a moderate trail
with workout segments A through G. The challenging trail is the
Avalanche Canyon trail 230 with workout segments H through P. And
the extreme trail is the Grand Teton trail 232 with workout
segments R through Z. Upon choosing an exertion level, the workout
will proceed along the workout segments until the trail end is
obtained. These end points for the trails are represented by 236a,
236b, and 236c. In an alternative embodiment, a user can select
their trail exertion level using a touch sensitive trail workout
panel 204. In such an embodiment an individual can simply select a
segment letter by pushing that letter or the general vicinity of
that letter, and the exercise apparatus would adjust the settings
to correspond to that portion or segment of the workout. It is also
envisioned that various embodiments would contain trails that
contained moderate, challenging, and extreme trail segments within
one workout.
[0069] The iFit.com button 244 is both a selector and an indicator.
The indicator light on the iFit.com button 244 demonstrates that a
connection has been established between the virtual trail system
and the external iFit.com system. The virtual trail system, if
properly connected to either a computer or directly to the Internet
through a communication line connection will use software to
contact the new www.iFit.com website to obtain the services of a
personal trainer. Examples of suitable communication line
connections include via PSTN, DSL, G-Lite, cable modem, wireless,
WAN line, radio frequency transmission, or other data connection.
Once the user initiates the iFit.com session via the interface by
depressing the iFit.com button 244, the virtual trail system
interacts with the website to obtain digital signals for the
workout session. If the online iFit.com trainer creates a "hill
climb" workout for the user, the incline of the treadbase 14 will
get steeper and steeper responsive to the personal trainer. The
iFit.com module uses a "plug in and logon" design to make it very
user friendly, even for users that are newcomers to the Internet.
One advantage of the iFit.com technology is its simplicity; all the
user needs to do is plug the iFit.com compatible fitness equipment
into their computer, an Internet access point or PSTN access line.
Once the connection is established, the workout options are
endless. For example, the user can select a daily iFit workout,
press "start," and the virtual trail system will begin following
the daily workout profile received from the offsite database.
[0070] An alternative embodiment allows the user to participate in
a live online workout session. The user designates their fitness
equipment and selects a personal trainer. The trainer can adjust
the equipment settings to constantly challenge the user while
monitoring the user's vitals, despite the fact that the user is
working out in the privacy and convenience of the user's own home.
It is well known by those skilled in the art that a personal
trainer helps keep a user motivated, makes the user more
accountable to their goals, and helps the user achieve better
results. The problem is, millions of consumers do not belong to
health clubs and therefore do not have access to qualified personal
trainers. Use of the iFit.com button 244 provides a new standard of
fitness at home. User's can schedule a private workout session with
a personal trainer conducted and monitored via computer cameras and
simultaneously sent by the trainer digital signals that control the
treadmill's electronic functions. As such, the present invention
becomes a truly interactive personal training experience.
[0071] The iFit.com connection uses Internet "streaming"
technology. Allowing consumers to quickly select and immediately
begin using a workout segment without downloading the entire
workout profile. The iFit.com streamable workouts are convenient
and easily accessed. Furthermore, the quality of personalized
workout sessions are improved, because ACE certified personal
trainers develop the workouts that are sent across the iFit.com
communication lines. Three predominant features are given to the
present invention through the iFit.com button 244. The first is
access to the basic iFit.com workout database that allows the user
to change his or her workout routine every day, thereby encouraging
site and workout "stickiness." The workout database streams into
the user's home computer or exercise device and gives the user
access to an electronic library of hundreds of preprogrammed
workouts whereas most treadmills have a maximum of only 6-8 basic
workouts. For example, users can adjust their treadmills to
accommodate a specialized preprogrammed 20-minute fat burning
workout or an 18-minute strength-training workout.
[0072] The second area of expansion are audio workouts, which give
the consumer a motivating combination of heart rate paced music and
the encouraging voice of a personal trainer. Digital signals in the
soundtrack control: resistance, speed, and incline of the fitness
equipment. The user will be able to choose from a variety of
musical styles and enjoy them within the confines of their home
workout area.
[0073] Finally, video workouts will stream to the virtual trail
system in two categories. The first workouts are group classes and
the second are hiking adventure series trails. Both types of
workouts feature heart rate paced music and digital signals to
control the exercise equipment. In the group class video, users
will watch a fun group "sweating it up" with a motivating personal
trainer leading the workout. The adventure series of workouts will
combine music, digital signals, and add engaging scenes of natural
beauty. One series features three hikes in the Grand Tetons.
Another running adventure series will be a workout following the
race course of the St. George Marathon in St. George, Utah, named
by Runner's World as the most scenic marathon in America. In this
manner, the hiker treadmill can be programmed to include training
workouts such as the incline and distances of activities like the
St. George Marathon. This would allow hiker treadmill users to
practice for a marathon in another state without requiring them to
travel to the location to run the course and, in essence, prepare
themselves for the eventual competition without being there. While
the functionality of the iFit.com button 244 is presently limited
to controlling the treadmill, in the foreseeable future such
workouts will interact with home stereos, TVs, VCRs, DVDs, and CDs
along with the treadmill to improve the quality of the interactive
feel of the exercise equipment.
[0074] One embodiment of the hiker treadmill allows the virtual
trail system to interface with a program that emulates a particular
climb. The program will provide virtual trail system with
adjustment codes that allow the hiker device to simulate the
terrain of a given hike. One method of programming a hike is
through analysis of the GPS coordinates for a starting point, one
or more weigh points, and an ending point. The virtual trail system
will then automatically compute the distances, inclines, to
simulate a hike along that course.
[0075] FIG. 3 is a control diagram for a virtual trail system with
trail workout incentives incorporated into the motivational display
console on an exercise device. At conditional action block 300 a
user may activate the machine through the insertion or input of an
access key. Selection block 305 determines whether the user desires
manual or trail based workout control. If the user desires manual
control, workout parameters may be established by direct adjustment
keypads for grade and speed, while variable keypads may provide
calorie, heart rate or other workout related restrictions. If trail
based control is selected, execution block 310 will identify the
user and restore the last trail position for that user. This
information may be encoded into the access key or may be stored in
memory relevant to the individual user. If there is no previous
workout information, the user will be placed at the beginning of a
trail. Decision block 315 determines whether the trail feature
button has been selected. If the trail feature button has been
selected, the available workout trails will cycle through and allow
the user to select and adjust various trail features for the user's
workout. These adjustments occur in execution block 325. If the
trail feature button has not been selected, the workout will begin
from the last trail position recorded according to the settings at
that point. At start point 320, a conditional execution block, a
user may activate the machine by pressing start. Once the exercise
device starts, execution block 330 allows adjustments to
inclination and speed to be made according to the workout trail
program until a trail feature button is selected. If a trail
feature button, as demonstrated by decision block 335 is selected,
then the user is allowed to adjust, modify and monitor various
trail features in execution block 340. These features include but
are not limited to trail elevation change, trail distance, segment
distance, segment vertical change, overall target difficulty for
trail and segment, and incline or speed adjustments. Once these
trail features have been adjusted, execution block 345 overrides
the standard segment settings with the modified values provided in
execution block 340. Generally this override occurs upon the
depression of the enter button 240 or the start key 224. The
controller then returns to the adjust incline and speed execution
block 330 and continues with the workout segment. Upon completion
of the workout segment, a stop exercise and store segment location
command is executed in execution block 360. If the trail features
are not manually adjusted in decision block 335, decision block 350
checks to see if the end of the workout segment has been reached.
If this end point has not been obtained, the workout program
returns the controller to the adjust inclination and speed
execution block 330.
[0076] FIG. 4 is a block diagram illustrating the process of
encoding a mountain trail, the creation of a workout profile, and
the standard operation of a previously encoded hike. Execution
block 400 instructs an automated controller or a trail designer to
collect trail data concerning the workout profile selected by the
user. This data structure is comprised of various elements
including a topographical information data string represented by
block 405 a programmed routine represented by 410, an iFit.com
program represented by block 415, a hike simulation represented by
420 and a hike recreation represented by 430. The topographical
information data structure 405 might include GPS coordinates for a
start point as well as one or more waypoints, segment breaks, and
an end point. Associated with each one of these GPS coordinates for
the waypoints, segment breakpoints, start points, and end points
would be a corresponding elevation value. The controller or trail
designer is then able to take this topographical information and
compute the distances, the average inclinations between the
waypoints, and simulate a hike from this data. Thus while a hike
may include variable length workout segments as well as variable
inclination adjustments.
[0077] A programmed routine 410 is comprised of inclination
adjustments and distances for workout segments compiled by a trail
designer to optimize the selected trail exertion. For example, a
moderate trail can contain grade adjustments from negative 5% to
positive 20%, while a challenging trail might include adjustments
from negative 10% to positive 40% and an extreme trail can include
adjustments from negative 15% to positive 60% in which some of the
segments might contain drastic 20% to 30% grade changes over
previous segments. The iFit.com programs 415 relate to programs
available over Internet sites and allow a user to access a new
trail each day.
[0078] Hike simulations 420 correspond to topographically entered
information or to hike simulation inserts that may be added to the
virtual trail system via PCMCIA, magnetic disk, PROM, flash
upgrades, or other storage means. For example, the Grand Teton
hikes displayed in FIG. 2 provide a user with a hike simulation for
the Avalanche Canyon trail, the Grand Teton trail and the Teepee
Glacier trail. Hike recreation 430 is data provided from a hike
monitor worn by an individual during a normal workout. This is an
exciting feature for the hiker as it allows an individual to
perform exercise when the weather prohibits outside exercise. In
essence the monitor records the distance and elevation changes
during the workout period and provides that information to the
exercise device through an interface or communication link.
[0079] Once the appropriate trail data is collected, execution
block 440 creates a workout hike profile. The hike development
module 450 collects information concerning distance, incline
adjustments, and average speed traveled. The hike development
module then creates individual workout segments to be chained
together for an overall workout profile. Blocks 455, 460, 465 and
470 illustrate examples of workout segments. Workout segment block
465 illustrates how the grade change can occur in 1% increments.
Workout block 455 demonstrates the grade 10% along with the
distance 0.05 miles. This also indicates the distance factor being
0.01 miles. Workout segment block 470 demonstrates the use of a
negative grade change as well as reemphasizing the potential for
0.01 miles distance changes. It is foreseeable that these grade
changes can be adjusted to angular slopes and that the distances
can be adopted as meters or kilometers. Once the workout profile
has been assembled containing the individual workout segments, the
hike is stored in execution block 480 for future playback on the
exercise device.
[0080] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative and not restrictive. The scope of
the invention is, therefore, indicated by the appended claims
rather than by the foregoing description. All changes that come
within the meaning and range of equivalency of the claims are to be
embraced within their scope.
