CAMERA SYSTEM FOR ADJUSTABLE VEHICLE FITTING SYSTEM
Abstract
An optimal configuration is determined based on operational
characteristics of an operator when operating an adjustable
stationary vehicle. A camera system is used to collect
anthropomorphic data about the operator to establish an initial
positioning of the components of the adjustable stationary vehicle.
The camera system can also be used to collect real-time information
about the operator's body positioning so as to cause adjustment of
the positioning of the components of the adjustable stationary
vehicle while being operated.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is based on and claims priority to U.S.
Provisional Patent Application Nos. 61/837,391 filed on Jun. 20,
2013, 61/837,396 filed on Jun. 20, 2013, and 61/926,877 filed on
Jan. 13, 2014, the disclosures of which are incorporated herein by
reference in their entirety for all purposes.
FIELD OF THE INVENTION
[0002] The present application relates to vehicle fitting systems,
particularly to an adjustable stationary bicycle or an adjustable
stationary motorcycle used as a fitting apparatus to determine the
optimal fit vehicle for a given rider and desired performance
characteristics, and more particularly to the use of a camera
system to facilitate such optimization.
BACKGROUND
[0003] In riding a bicycle, the pedaling power of the user is a
primary factor in determining how fast the rider will get to the
destination. There are other factors associated with the bicycle
and the interaction between the rider and the bicycle, such as the
wind resistance (i.e., drag coefficient) and the weight of the
rider and/or bicycle. In order to optimize the power output of the
rider on the bicycle, it is important that the bicycle be of
appropriate dimensions for the rider. The rider must be in an
aerodynamic riding position as much as possible, but the position
should also affect the breathing and the pedaling of the rider as
little as possible. The pedaling power is directly related to the
heart rate of the rider and adequate breathing is essential to an
optimized riding position.
[0004] At present, when purchasing a bicycle, a rider moves onto
the bike having its rear wheel supported by a trainer. According to
the salesman's experience, various adjustments are made (vertical
and horizontal position of the seat, stem length and handlebar
height) until a suitable riding position is reached, often as
visually decided by the salesman. The rider must at the very least
stop pedaling and lean forward to make adjustments to the seat. In
some instances, the rider must come off the bicycle for adjustments
to be made and obviously must completely dismount to test a
different frame size. Similarly, cyclists who desire the optimal
performance of their bicycle may wish to measure the effect of
various configurations and equipment positions to ensure the best
arrangement for a desired performance, e.g., sprint, triathlon,
endurance, etc. Such an optimization generally requires the
repeated and manual adjustment of the seat, handlebars, etc.
[0005] Several motorized or mechanically actuated devices have been
designed in an effort to streamline the bicycle fitting process.
For example, U.S. Pat. No. 7,905,817 to Giannascoli et al., the
disclosure of which is incorporated herein by reference for all
purposes, discloses a stationary bicycle with motor-adjustable
translational joints between the frame and the handlebars and the
frame and the seat. This design enables the adjustment of the
relative positions of the seat and handlebars with respect to the
crank while the rider is positioned on the stationary bicycle. As
further disclosed in U.S. Appl. Pub. No. 2013-0065733 to Kautz et
al., the disclosure of which is incorporated herein by reference
for all purposes, the best fitting bicycle frame may be determined
using a stationary bicycle such as the one disclosed in Giannascoli
et al. and measuring power, cadence, and other parameters
associated with the performance of the rider under various setup
positions. Another design of a motorized or mechanically-driven
adjustable stationary bicycles is disclosed in U.S. Appl. Pub. No.
2011-0237397 to Mabey et al., the disclosure of which is
incorporated herein by reference. The Mabey et al. design
incorporates numerous mechanical actuators to adjust the relative
position of the handlebars and seat with respect to the crank based
on verbal feedback from the rider and power measurements taken by
the device.
[0006] In addition, there are prior art camera or biometric
measurement based systems known for use in bicycle fitting. For
example, U.S. Appl. Pub. Nos. 2007-0142177, 2010-0076721, and
2010-0306160 to Simms all relate to systems for using physical
measurements of a cyclist and visual marker tracker systems to
assist in the bicycle fitting process.
[0007] As with bicycles, a rider's position on a motorcycle can
affect how well the rider is able to manipulate the motorcycle and
can affect the performance of the rider. Different performance
characteristics are desired depending on the type of motorcycle and
type of riding involved, e.g., off road vs. on road, endurance vs.
sprint, and competitive vs. leisure riding. It is therefore
desirable to optimally fit a motorcycle to the rider in terms of
body as well as type of riding. Configurations can vary greatly
depending on the circumstances. For example, an optimal motorcycle
or motorcycle configuration for a rider who is 6'5'' tall engaging
in cross-country touring is very different from the optimal
motorcycle or motorcycle configuration for a rider who is 5'8''
tall participating in competitive off road motocross events.
Historically, fitting a motorcycle to a rider has been performed by
educated guesswork and trial and error. The inclusion into the
fitting mix of various designs for aftermarket handlebars and other
customization options makes fit optimization all the more
difficult.
[0008] The prior art mechanical and motor-driven adjustable
stationary bicycles all suffer to varying degrees from one or more
of the following deficiencies: significant stand-over height making
it difficult for smaller riders to use the devices; numerous
expensive actuators/motors required to accomplish adjustments
increasing the cost and service requirements for the devices;
inability to provide a simulated climbing or descending of hills to
replicate actual riding conditions; and multiple crank positions
are required to accommodate different riders. Existing fitting
techniques for optimizing a motorcycle configuration are
rudimentary at best. As such, there is a need for an adjustable
vehicle fitting system that overcomes some or all of these
shortcomings. Similarly, the existing systems for including
biometric information in the fitting process suffer from various
shortcomings, such as an inability to offer real-time adjustments
while the rider is actively riding or simulating riding and the
inability to effectively pre-fit a rider.
[0009] It will be understood by those skilled in the art that one
or more aspects of this invention can meet certain objectives,
while one or more other aspects can lead to certain other
objectives. Other objects, features, benefits and advantages of the
present invention will be apparent in this summary and descriptions
of the disclosed embodiment, and will be readily apparent to those
skilled in the art. Such objects, features, benefits and advantages
will be apparent from the above as taken in conjunction with the
accompanying figures and all reasonable inferences to be drawn
therefrom.
SUMMARY
[0010] One embodiment of the invention includes a stationary
bicycle having a frame, a foot support, such as a crank set
rotatably mounted to the frame or a foot peg, a handlebar
adjustably disposed on the frame to be adjustable in X and Y
directions relative to the crank set, a seat adjustably disposed on
the frame to be adjustable in X and Y directions relative to the
crank set, a mechanism operably connected to the handlebar and the
seat to facilitate adjustment of the respective handlebar and seat
in the X and Y directions, and a bicycle controller. In one
alternative embodiment, the stationary bicycle can be mounted to a
base such that the frame is pivotable with respect to the base to
help simulate uphill or downhill cycling conditions more
effectively than a simple adjustment of wheel resistance. The
bicycle controller system facilitates: movement of the handlebar
and the seat in the X and Y directions; determination of an optimal
bicycle frame size for a rider based on operational characteristics
provided by the rider when riding the stationary bicycle;
determination of a best-fit bicycle frame size that is a closest
match to the optimal frame size based on a comparison of available
frame sizes stored in a database, the best-fit bicycle frame having
a head tube and a seat tube; determination of at least one of the
optimal X,Y location of the handlebar relative to the foot support
based on the location of the rider's hands, and the optimal X,Y
location of the seat relative to the foot support based on the
location of the rider's derriere; determination of a stem and
spacer from a list of available stems and spacers that will best
fit between the head tube of the best-fit frame and the optimal X,Y
location of the handlebar; determination of a seat post from a list
of available seat posts that will best fit between the seat tube of
the best-fit frame and the optimal X,Y location of the seat; and
output of a list of the best-fit frame, the best fit stem and
spacer, and the best fit seat post. The initial positioning of the
stationary bicycle components, as well as their real-time
adjustment while the rider is operating the bicycle, can be
assisted through the use of a camera system that collects
anthropometric data about the rider and provides it to the
controller system.
[0011] An embodiment of the invention includes a method for using
an adjustable stationary bicycle to determine an optimal bicycle
frame size and/or an optimal setup of the frame, seat, and
handlebars for a rider based on operational characteristics
provided by the rider when riding the adjustable stationary
bicycle. A best-fit bicycle frame size that is a closest match to
the optimal frame size based on a comparison of available frame
sizes stored in a database, the best-fit bicycle frame having a
head tube and a seat tube, is determined. At least one of the
optimal X,Y location of the handlebar relative to the foot support
based on the location of the rider's hands, and the optimal X,Y
location of the seat relative to the foot support based on the
location of the rider's derriere, is determined. A stem and spacer
from a list of available stems and spacers that will best fit
between the head tube of the best-fit frame and the optimal X,Y
location of the handlebar is determined. A seat post from a list of
available seat posts that will best fit between the seat tube of
the best-fit frame and the optimal X,Y location of the seat is
determined. A list of the best-fit frame, the best fit stem and
spacer, and the best fit seat post, is produced. The initial
positioning of the stationary bicycle components as well as their
real-time adjustment while the rider is operating the bicycle can
assisted through the use of a camera system that collects
anthropometric data about the rider and provides it to the
controller system that adjusts the positions of the components of
the adjustable stationary bicycle.
[0012] One additional embodiment of the invention includes a method
for using an adjustable stationary motorcycle to determine an
optimal motorcycle and/or an optimal setup of a motorcycle for a
rider based on operational characteristics provided by the rider
when simulating the riding of the motorcycle. A best-fit motorcycle
that is a closest match to the optimal motorcycle based on a
comparison of available sizes and types stored in a database is
determined. At least one of the optimal X,Y location of the
handlebars relative to the foot pegs based on the location of the
rider's hands, and the optimal X,Y location of the seat position
relative to the foot pegs based on the location of the rider's
derriere, is determined. A handlebar from a list of available
handlebars that will best fit the rider based on the optimal X,Y
location of the handlebar is determined. A seat from a list of
available seats that will best fit the rider based on the optimal
X,Y location of the seat is determined. A list of the best-fit
motorcycle, the best fit handlebars, and the best fit seat, is
produced. The initial positioning of the components as well as
their real-time adjustment while the rider is simulating operating
the motorcycle can assisted through the use of a camera system that
collects anthropometric data about the rider and provides it to the
controller system that adjusts the positions of the components.

DETAILED DESCRIPTION
[0044] The present invention contemplates the use of an adjustable
vehicle fitting apparatus to determine the optimal fit for a
particular vehicle rider based on various objectives, e.g.,
comfort, speed, endurance, body position, sprint capability, etc.
Disclosed are several embodiments of adjustable stationary bicycles
or motorcycle fitting apparatus, a system and method for operation
of the bicycles and motorcycle fitting apparatus, and the use of a
camera system to collect anthropomorphic data for use in the
initial setup of the vehicle fitting apparatus and to make
real-time adjustments to the setup while the vehicle fitting
apparatus is being operated by the rider.
[0045] While certain embodiments are described in detail with
respect to an adjustable stationary bicycle, for expediency they
are not repeated with respect to an adjustable stationary
motorcycle. It should be understood that similar designs and
configurations could be used as an adjustable stationary
motorcycle, the primary difference being foot pegs on the
motorcycle instead of the crank and pedals used in a bicycle. The
foot pegs in the adjustable stationary motorcycle embodiment may be
repositionable and optimized. In addition, the system and
optimization method described in detail with respect to bicycle
selection and fitting can be implemented in the same fashion in
motorcycle selection and fitting.
[0046] Referring now to the drawings and more particularly to FIGS.
1 to 3, a prior art adjustable stationary bicycle is generally
shown at 10. The stationary bicycle 10, has a base 11, a frame 12,
an exercise wheel 13, a foot support in the form of a crank set 14,
a seat 16 and a handlebar 18. The base 11 supports a remainder of
the bicycle 10. The base 11 is for instance mounted on the floor.
When the cycle is a motorcycle, the foot support is a foot peg (not
shown).
[0047] A frame 12 is connected to the base 11. The frame has a
horizontal longitudinal axis parallel to the base 11, and supports
the various user interface components of the bicycle 10, namely the
crank set 14, the seat 16 and the handlebar 18.
[0048] The exercise wheel 13 is related to the crank set 14. The
power output of the user of the bicycle 10 is typically measured
using the exercise wheel 13. The exercise wheel 13 is also actuated
to control the resistance to pedaling. The crank set 14 has pedals
(not shown) and receives the pedaling actuation from the user of
the bicycle 10. The pivot axis of the crank set 14 relates to the
pivot axis of a crank set of a bicycle pivotally disposed in the
bicycle frame.
[0049] The seat 16 supports the user of the bicycle 10 in a riding
position. The handlebar 18 is provided as a support for the arms of
the user (and is obviously used for steering on a real
bicycle).
[0050] The frame 12 has a support beam 20 by which it is connected
to the base 11. The support beam 20 has a chain stay, and the
exercise wheel 13 is mounted within the chain stay in a rotational
relation. Although not shown, a chain/chain ring and gears,
belt/pulleys or similar transmissions are provided between the
wheel 13 and the crank set 14 for the transmission of the pedaling
power of the user to the wheel 13.
[0051] A rail 22 is supported by the support beam 20. In an
embodiment, the rail 22 is generally parallel to the ground. A
carriage 23 is slidingly mounted onto the support beam 20, so as to
form a prismatic joint therewith (i.e., translational one-DOF
joint). As it is supported by the carriage 23, the seat 16 is
displaceable in translation along the X-axis. The prismatic joint
formed by the rail 22 and the carriage 23 is actuated by actuator
24.
[0052] A seat tube 25 is connected to the carriage 23 and in an
embodiment is in a perpendicular relation therewith. A seat post
support 26 is telescopically engaged into the seat tube 25, so as
to form another prismatic joint. As the seat post of the seat 16 is
locked to the seat post support 26, the seat is displaceable in
translation along the Y-axis. The prismatic joint formed by the
seat tube 25 and the seat post support 26 is actuated by actuator
27.
[0053] The handlebar 18 is also displaceable in translation along
the X-axis and the Y-axis. More specifically, a carriage 30
supporting the handlebar 18 is operatively mounted to a front end
of the rail 22, thereby forming a prismatic joint. The direction of
the carriage 30 is along the X-axis. In the illustrated embodiment,
the displacement of the handlebar 18 along the X-axis is actuated
by actuator 31.
[0054] A head tube 32 is mounted to the carriage 30, and in an
embodiment, is in a perpendicular relation therewith. A bracket 33
is telescopically inserted into the head tube 32 so as to form a
prismatic joint displaceable along the Y-axis direction. Actuator
34 powers the prismatic joint along the Y-axis direction.
[0055] Although the actuators 24, 27, 31 and 34 are preferably
electrically powered linear actuators, it is contemplated to use
either stepper motors or manual actuation as well. The
translational degrees of freedom of the seat 16 and of the
handlebar 18 are mechanically controlled and
self-supported/self-locked such that actuation is required to
displace the seat 16 and/or handlebar 18. In the illustrated
embodiments, the seat 16 and handlebar 18 are therefore fixed into
X and Y positions, and can only be displaced by actuation of the
prismatic joints. Therefore, the seat 16 and the handlebar 18 are
displaceable even while a rider is supported in a riding
position.
[0056] The bracket 33 is a quick-release mechanism allowing
different handlebars 18 to be mounted rapidly onto the stationary
bicycle 10. Alternatively, a handlebar extendable in a Z-axis
(perpendicular to both the X- and Y-axes according to an orthogonal
set of X-Y-Z axes) is considered.
[0057] Although not shown, the crank set 14 is preferably of the
extendable type, in that the cranks can be adjusted to different
lengths. One contemplated crank set system has the cranks pivotally
off-center from the chain ring, so as to be adjustable to different
crank lengths.
[0058] Various sensors are provided in order to measure the
performance of the rider on the stationary bicycle 10. For
instance, referring to FIG. 5, a power sensor 40 and a cadence
sensor 41 are respectively provided in association with the
exercise wheel 13 and the crank set 14 to measure the pedaling
power and the cadence of a rider. Other configurations for these
sensors, and for other sensors 42, are considered, such as a
heart-rate monitor, pressure sensors for the pedals, etc.
[0059] The stationary bicycle 10 take different configurations to
enhance its stiffness. Referring to FIG. 4, another prior art
version of the stationary bicycle is also illustrated as 10, but
features a frame 12' that is different than the frame 12 of the
stationary bicycle of FIGS. 1 to 3. Many components are similar
between the stationary bicycles 10 of FIGS. 1-3 and of FIG. 4,
whereby like parts will bear like reference numerals. The frame 12'
has a pair of guideways 22' supporting the carriage 23', such that
the carriage 23' is displaceable in translation along the X-axis,
enabling the horizontal adjustment of the seat 16. The carriage 23'
consists of a pair of parallel plates that support the seat tube
25. Similarly, the frame 12' has a pair of guideways 22''
supporting the carriage 30', such that the carriage 30' is
displaceable in translation along the X-axis, further enabling the
horizontal adjustment of the seat 16. The carriage 30' consists of
a pair of parallel plates that support the head tube 32. The
configuration of the frame 12' (FIG. 4), although similar in
construction to the frame 12 (FIG. 1-3), provides added structural
rigidity to the stationary bicycle 10. Alternative frame
configurations are considered as well.
[0060] An improved embodiment of an adjustable stationary bicycle
is shown in FIGS. 14-30. This improved embodiment may be used with
the system and processes described herein as well as with the
camera system embodiment for collecting anthropomorphic data for
both initial setup and in real-time to make adjustments. For
clarity, reference numerals referring to this embodiment will be
prefaced with the letter "B." Referring now to the drawings an
adjustable stationary bicycle in accordance with this embodiment of
the invention is generally shown at B28. The stationary bicycle B28
generally has a base B30, a frame B40, a wheel B82, a crank set
B46, a seat B134 and handlebars B138. The frame B40 has a
horizontal longitudinal axis parallel to the base B30.
[0061] The base B30 supports the bicycle B28. The base B30 can be
mounted on the floor or is otherwise sufficiently sturdy to bear
the weight and movement of the bicycle B28 and the rider. As best
shown in FIGS. 14-20, the base B30 includes a base column B32 with
base legs B34 at either end thereof.
[0062] A frame B40 is connected to the base B30 via clevis B36. In
the embodiment shown, frame B40 includes two side panel members
with a center frame column B42 (see FIG. 21) there between. A top
guard B44 covers the top area over the open area between the two
side panels. The clevis B36 is formed from two side panels
connected to the base column B32. Center frame column B42 is
pivotally connected to clevis B36 at clevis pivot B38 so that, as
the center frame column B42 pivots, the frame B40 tilts the bicycle
B28 forward or backward to simulate an uphill or downhill riding
position.
[0063] As best shown in detail in FIGS. 21-24, the tilting of the
frame B40 is accomplished using a base actuator B56 within the base
column B32. The base actuator B56 includes a motor B60 operatively
connected to a ballscrew B58. The connection may be direct, via
gearing, belt drive, or otherwise. Engaged to the ballscrew B58 is
a ball nut B64 that is attached to a pivotable yoke block B62 at
the end of the center frame column B42. The motor B60 selectively
rotates the ballscrew B58 so as to move the ball nut B64 along its
length. As the ball nut B64 moves, it causes movement of the yoke
block B62 at the end of the center frame column B42 thereby causing
the center frame column B42 (with frame B40 attached) to pivot
about clevis pivot B38. Thus, activation of the motor B60 in the
base actuator B56 can tilt the frame B40 forward or backward to
simulate for the rider of the bicycle B28 the feeling of riding
uphill or downhill. This feeling is enhanced by appropriate
modification of the resistance provided to pedaling, as described
below.
[0064] The frame B40 supports the various user interface components
of the bicycle B28, namely the crank set B46, the chain stay B50
(with chain B52 between the crank set and the wheel B82 supported
by the chain stay B50), the seat B134 and the handlebars B138. A
mount B100 for a resistance/measuring device B142 is attached to
the chain stay B50 or frame B40 for interaction with wheel B82.
[0065] The wheel B82 is connected to the crank set B46 via chain
B52 or other means such as a belt drive so as to result in rotation
of the wheel B82 when pedals (not shown) attached to the crank set
B46 are actuated by a rider. The power output of the user of the
bicycle B28 is typically measured using the wheel B82 through a
resistance and measuring device B142 as is well known in the art.
Alternatively, resistance and power output measurement could be
provided directly at the crank set B46 but it has been found
preferable to use a rotating wheel B82 for enhanced user
experience.
[0066] The seat B134 supports the user of the bicycle B28 in a
riding position. As shown in detail in FIG. 17 and generally in
FIGS. 32, 33, and 26, the seat B134 is attached to the frame B40
through seat slide assembly B102. Seat B134 is attached to a seat
clamp B136 which is preferably a quick-release seat clamp to enable
quick changing of the seat B134. The seat clamp B136 is attached to
the seat slide assembly B102 via traveler B112 on carriage B110
that slidingly rests on rail B108. Carriage B110 can slide along
the length of rail B108 which is affixed to the base B104 of the
seat slide assembly B102. Motor B116 of the seat slide assembly
B102 is operably attached to rotatable rod B114. The connection may
be direct, via gearing, belt drive, or otherwise. When motor B116
is activated it causes rotation of rod B114 which is threadingly
engaged to traveler B112. Because of the threaded engagement and
non-rotatable securing of traveler B112 to carriage B110, rotation
of the rod B114 causes the traveler 112 to move along the length of
the rod B114 and movement of the seat B134. As best seen in FIG.
18, cover B106 is provided to cover the seat slide assembly
B102.
[0067] The handlebars B138 are provided as a support for the arms
of the user. As shown in detail in FIG. 29 and generally in FIGS.
32, 33, and 36, the handlebars B138 are attached to the frame B40
through handlebar slide assembly B118. Handlebars B138 are attached
to a handlebar clamp B140 which is preferably a quick-release clamp
to enable quick changing of the handlebars B138. The handlebar
clamp B140 is attached to the handlebar slide assembly B118 via
traveler B128 on carriage B126 that slidingly rests on rail B124.
Carriage B126 can slide along the length of rail B124 which is
affixed to the base 120 of the handlebar slide assembly 118. Motor
132 of the handlebar slide assembly B118 is operably attached to
rotatable rod B130. The connection may be direct, via gearing, belt
drive, or otherwise. When motor B132 is activated it causes
rotation of rod B130 which is threadingly engaged to traveler B128.
Because of the threaded engagement and non-rotatable securing of
traveler B128 to carriage B126, rotation of the rod B130 causes the
traveler B128 to move along the length of the rod B130 and movement
of the handlebars B138. As best seen in FIG. 18, cover B122 is
provided to cover the handlebar slide assembly B118.
[0068] As shown generally in FIGS. 14, 15, 18, and 25 and in more
detail in FIGS. 26-28, seat actuator B66 is positioned on frame
B40. Seat actuator B66 provides a moveable platform on which seat
slide assembly B102 is positioned. Seat actuator B66 includes,
extending through a top guide B66 that helps maintain them in
position, rods B76 for providing stability to the assembly, shaft
B74 for effectuating movement, and cable tube B78 for routing of
the various control and power cables needed for the motors,
measuring devices, etc. A ball screw B72 is threadingly positioned
at the end of shaft B74. Motor B80 of the seat actuator B66 is
operably attached to shaft B74. The connection may be direct, via
gearing, belt drive, or otherwise. Because of the threaded
connection between the shaft B74 and the ball screw B72, when ball
screw B72 is caused to rotate, shaft B74 moves along its length
causing the top end of the seat actuator B66 (on which the seat
slide assembly B102 is affixed) to move thereby repositioning the
seat B134. As best illustrated in FIG. 28, as shaft B74 moves, rods
B76 (whose primary purpose is to provide stability) slide within
the seat actuator B66. As best seen in FIG. 18, housing B70 covers
the various moving parts comprising the seat actuator B66.
[0069] As shown generally in FIGS. 14, 15, 18, and 25 and in more
detail in FIGS. 26-27, handlebar actuator B84 is positioned on
frame B40. Handlebar actuator B84 provides a moveable platform on
which handlebar slide assembly B118 is positioned. Handlebar
actuator B84 includes, extending through a top guide B86 that helps
maintain them in position, rods B94 for providing stability to the
assembly, shaft B92 for effectuating movement, and cable tube B96
for routing of the various control and power cables needed for the
motors, measuring devices, etc. A ball screw B90 is threadingly
positioned at the end of shaft B92. Motor B98 of the handlebar
actuator B84 is operably attached to shaft B92. The connection may
be direct, via gearing, belt drive, or otherwise. Because of the
threaded connection between the shaft B92 and the ball screw B90,
when ball screw B90 is caused to rotate, shaft B92 moves along its
length causing the top end of the handlebar actuator B83 (on which
the handlebar slide assembly B118 is affixed) to move thereby
repositioning the handlebars B138. The movement of the handlebar
actuator B84 is similar to that illustrated in FIG. 28 with respect
to the seat actuator B66. As best seen in FIG. 18, housing B88
covers the various moving parts comprising the handlebar actuator
B84.
[0070] As best seen in FIG. 26, the seat actuator B66 is angled
relative to perpendicular to the frame horizontal axis, and the
handlebar actuator B83 is angled relative to perpendicular to the
frame horizontal axis.
[0071] Thus, the coordinated and controlled activation of the motor
B60 of the base actuator B56, the motor B80 of the seat actuator
B66, the motor B98 of the handlebar actuator B84, the motor B116 of
the seat slide assembly, and the motor B132 of the handlebar slide
assembly enables the power tilting of the frame B40, and X-Y
adjustment of the positions of the seat B134 and handlebars B138.
In other embodiments, other methods of power tilting (not shown)
can be used.
[0072] Although the motors are preferably stepper motors,
electrically powered linear actuators, hydraulic actuators, and/or
other types of motors or manual actuation could be used as well.
The translational degrees of freedom of the seat B134 and of the
handlebars B138 are mechanically controlled and
self-supported/self-locked such that actuation of the motors is
required to displace the seat B134 and/or handlebars B138. In the
illustrated embodiment, the seat B134 and handlebars B138 are
therefore fixed into X and Y positions, and can only be displaced
by activation of the actuators.
[0073] Various sensors are provided in order to measure the
performance of the rider on the bicycle B28. For instance,
referring to FIG. 15, a power sensor and a cadence sensor can be
provided in association with the wheel B82 and the crank set B46 to
measure the pedaling power and the cadence of a rider. In the
illustrated embodiment such sensors are part of the
resistance/measuring device B142. Other configurations for these
sensors, and other sensors, are considered, such as a heart-rate
monitor, pressure sensors for the pedals, etc. For example,
pressure sensors for all contact points of the rider (pedals, seat,
handlebars) could be included.
[0074] Referring to FIG. 5, a stationary bicycle controller system
in accordance with an embodiment is generally shown at 50. The
bicycle controller system 50 is used in all illustrated bicycle
configurations, and is in communication with the actuators 24, 27,
31 and 34, as well as with the sensors 40, 41 and 42. The bicycle
controller system 50 has a bicycle controller 51 that is a
processing unit (PC, microprocessor, or the like). The bicycle
controller 51 receives data from the power sensor 40, the cadence
sensor 41 and the other sensors 42. In the embodiment wherein a
camera is used to collect anthropomorphic data described below, the
camera is also connected to the bicycle controller 51.
[0075] A position commander 52 is connected to the bicycle
controller 51, and is in association with the actuators 24, 27, 31
and 34. More specifically, the actuation of the actuators 24, 27,
31 and 34 is controlled by the commander 52. A position calculator
53 is connected to the position commander 52 and determines the
position of the seat 16 and the handlebar 18 in the X-Y coordinate
system illustrated in FIGS. 1 to 3.
[0076] As an example, a reference point for the X and Y coordinates
of the seat 16 and the handlebar 18 is a center of the crank set
14, which correlates with the center of the foot support of a
bicycle frame. Considering that the feet of the rider are locked to
the cranks of the crank set 14, the center of the crank set 14
constitutes a fixed point well suited to be used as a reference for
the position of the seat 16 and the handlebar 18.
[0077] The position calculator 53 may operate in different ways.
For instance, in an embodiment a calibration is performed every
time the stationary bicycle 10 is turned on, so as to relate the
degree of actuation of the actuators 24, 27, 31 and 34 to X and Y
positions relative to the reference. In an embodiment, the
actuators 24, 27, 31 and 34 are subjected to a homing movement
(moved to a null extension) to be calibrated. Alternatively,
sensors 202, 204, 206, 208 (see FIG. 5) may be provided in the
actuators 24, 27, 31 and 34, or on the various prismatic joints, so
as to detect the XY positions of the seat 16 and the handlebar 18
with respect to the reference. The use of sensors is considered for
manually actuated mechanisms of displacements for the seat 16 and
the handlebar 18.
[0078] A profile calculator 54 is connected to the bicycle
controller 51. The profile calculator 54 receives the various data
from the sensors 40-42, as well as the X and Y positions of the
seat 16 and the handlebar 18, as a function of time. Accordingly,
the performance of the rider (pedaling power, cadence, heart rate,
for example) is related to the dimensions of the stationary bicycle
10. All information is related to rider identification and
characteristics (e.g., name, anthropometric measurements, weight,
age, etc.) in the form of a rider profile in a rider profile
database 55. Additional information can be recorded under the rider
profile, such as the preferred dimensions of the stationary bicycle
10.
[0079] A user interface 56 is connected to the bicycle controller
51. The user interface 56 is typically a monitor with touch keys or
a keyboard, through which the user interface 56 is commanded and
information is entered (e.g., rider identification). In an
embodiment, the user interface 56 displays actuator controls, for
the manual control of the actuation of the actuators 24, 27, 31 and
34. It is considered to provide a touch-screen with icons
representing available directions of displacement for the seat 16
and the handlebar 18. The user interface 56 may include other
peripherals, such as a printer, ports for plug-in devices (e.g.,
USB port), digital camera, etc. Smart cards and chip cards or
internal storage can be used to store the rider profile.
[0080] Amongst the various applications considered, the use of the
stationary bicycle 10 as a training device in a gym setting is
contemplated. When a rider wants to use the bicycle 10, his/her
identification is entered into the bicycle controller system 50,
whereby the rider profile is retrieved from the database 55. The
bicycle controller 51 transmits the information to the position
commander 52 such that the size of the stationary bicycle 10 is
adjusted as a function of the rider identification. In the
embodiment wherein a camera is used to collect anthropomorphic data
described below, the camera could be used to collect measurements
from the rider to adjust the component positions rather than
reliance on information from database 55.
[0081] For a new user of the stationary bicycle 10, a rider profile
is created and saved in the rider profile database 55. It is
considered to provide statistical data relating anthropometric data
of users to desired bicycle dimensions. Accordingly, by entering
anthropometric data pertaining to a user, the bicycle controller 51
can select a suitable bicycle size as a function of the
anthropometric data. In the embodiment wherein a camera is used to
collect anthropomorphic data described below, the camera can
collect the data and transmit it directly to the bicycle controller
51. As described hereinafter, a frame size calculator 57 is used to
select a suitable bicycle size from the anthropometric data.
Alternatively, from statistical data, formulas can be derived to
determine initial bicycle dimensions as a function of
anthropometric data. In an embodiment discussed below in connection
with method 500 (FIG. 9), the functionality of frame size
calculator 57 is expanded to include determination of a best fit
bicycle frame, stem, spacer(s), and seat post. Further additional
functionality of frame size calculator 57 discussed below includes
determination of riding apparel suitable for the person/rider being
fitted. As such, the term "frame size calculator" could be replaced
with the term "custom calculator," and still be consistent with the
description of the invention described herein.
[0082] Moreover, the rider profile may include the performance of
the rider at different bicycle dimensions. Therefore, an optimal
bicycle size can be determined from the review of the information
gathered in the database 55 following calculations by the profile
calculator 54. This is particularly useful for elite athletes.
Alternatively, a trainer can assist the rider in trying different
bicycle sizes, to then enter the dimensions, at a position selected
by the trainer or the rider.
[0083] As another application, the stationary bicycle 10 is used as
a fitting apparatus to determine an optimal bicycle size for
particular objectives. The stationary bicycle 10 is used with the
controller system 50 to gather performance information associated
with bicycle size. The use of actuators 24, 27, 31 and/or 34
enables a dynamic fitting. More specifically, the controller system
50 may direct a plurality of incremental changes to have the rider
try various adjusted positions while not interrupting his/her
pedaling. As an alternative, the rider profile data from the
database 55 may then be interpreted to identify the optimal
position. With the rider profile, the optimal bicycle size
(according to the type of bicycle, such as road bike, mountain
bike, cyclo-cross bike, etc.) for the rider can be determined.
[0084] When the stationary bicycle 10 is used as part of a fitting
apparatus, it is considered to provide the controller system 50
with the frame size calculator 57. The frame size calculator 57
receives the actual position data from the bicycle controller 51
(i.e., the adjusted position following testing by the user), and
produces frame size data, and possibly other data such as stem
length and angle, spacer combinations, handlebar dimensions, and
seat post dimensions. The frame size calculator 57 is also provided
to identify initial seat and handlebar positions from the
anthropometric data of the user (which can be collected by a camera
in one embodiment). The frame size calculator 57 typically selects
starting seat and handlebar positions from statistical data
relating bicycle size to anthropometric data. For this purpose, the
bicycle controller 51 is connected to the internet 58, to access a
remotely-located server comprising the statistical data tables
associating bicycle/frame sizes to anthropometric data. These
statistical data tables are typically updated with any new user
recording adjusted bicycle dimensions as a function of
anthropometric data. Alternatively, the data could be locally
stored in a database to avoid the need for a connection to the
internet 58.
[0085] The frame size data calculated by the frame size calculator
57 can represent enough information for a user (e.g., salesman) to
select a bicycle of correct size. As an example, the X and Y
coordinates of the seat and of the handlebars are given with
respect to the pivot axis of the crank set, the reference. A tool
(e.g., a t-shaped ruler) may then be provided to measure a bicycle
to determine whether it has the right size. Accordingly, a store
salesman can readily pick bikes from the inventory by having the
required dimensions of the bike, and means to measure the bike.
[0086] Alternatively, the user interface 56 may produce data in the
form of savable files. For instance, the frame size data may be
printed out, or saved, to be sent to a supplier or a manufacturer
of bicycles. Similarly, the bicycle controller 51 may be connected
to the internet 58, so as to forward bike dimensions to a
manufacturer of bicycles. In the case of custom-made bicycles, the
delay between the fitting of a bicycle is reduced with the use of
the controller system 50.
[0087] Additional information can be obtained. For instance, it is
considered to place the stationary bicycle 10 in a wind tunnel in
order to obtain the rider's drag coefficient as a function of the
effect of the size of the bicycle on the riding position. This
information is then related to the performance of the rider to
determine the optimal size of the bicycle for the rider. In the
embodiment, where a camera is used to collect real-time
anthropomorphic data, the camera could be further used to provide
an estimated rider drag coefficient based on the positioning of the
rider.
[0088] It is also considered to use the stationary bicycle as a
motion simulator for video games or riding simulations. The
stationary bicycle 10 can provide force feedback in the form of
resistance in the exercise wheel 13, as well as through actuation
of the actuators 24, 27, 31 and/or 34 to simulate the vibrations of
a bicycle. In the alternative embodiment, where the frame can be
tilted forward and back, the tilting can be used to better simulate
uphill and downhill riding conditions.
[0089] In FIG. 6, a method 100 for adjusting a stationary bicycle,
such as the stationary bicycle 10 of FIGS. 1 to 4, for instance
used in combination with the stationary bicycle control system as
described in FIGS. 1 to 5, is explained. FIG. 13 reflects an
alternative embodiment for a method of adjusting a stationary
bicycle wherein a camera system can be used both in determining the
setup starting position (using the camera-collected anthropomorphic
information) and in making component position adjustments (using
the camera-collected joint angle and relative positioning data) in
real-time as the rider is operating the bicycle.
[0090] FIG. 13A reflects an additional embodiment where the vehicle
to be fit is a motorcycle. In this embodiment, the camera system
can be used both in determining the setup starting position (using
the camera-collected anthropomorphic information) and in making
component position adjustments (using the camera-collected joint
angle and relative positioning data, as explained below) in
real-time as the rider is simulating riding the motorcycle. The
process is similar to that used in the bicycle embodiment, but can
include different variables for optimization because of the
differences in the vehicle types. For example, where the bicycle
embodiment measures power output, that is not a rider based factor
in motorcycles. But, foot peg positioning can be an important
function that will drive the selection of the optimal motorcycle or
adjust fitting.
[0091] In step 102, data associated with the user of the stationary
bicycle is obtained. In one embodiment, if it is the first time the
user tries the stationary bicycle, the data is typically
anthropometric data pertaining to the leg length (e.g., measured at
the crotch), the torso dimensions, the arm length of the user, and
the shoulder width. In the embodiment including a camera, this
anthropomorphic data can be obtained by the camera and provided
directly to the system. Additional information, such as user
restrictions (e.g., back pain, knee problems, or the like), may
also be recorded.
[0092] In another embodiment, in which the stationary bicycle is
used in a training environment and the user already has a profile
recorded in the stationary bicycle control system 50 (FIG. 5), the
data obtained in step 102 is an identification of the user. By
obtaining the identification of the user in step 102, the
stationary bicycle control system 50 can load stationary bicycle
dimensions as prerecorded in a user profile following a previous
adjustment session.
[0093] In step 104, the dimensions of the stationary bicycle are
selected as a function of the user data obtained in step 102. More
specifically, if the data is anthropometric in nature, the
stationary bicycle control system obtains typical dimensions from
statistical data tables relating anthropometric data of numerous
users to average dimensions associated with such data. In another
embodiment, the selected dimensions of the stationary bicycle are
provided with a user profile.
[0094] In step 106, the stationary bicycle is actuated to the
selected dimensions using the various actuators described in FIGS.
1 to 5. In step 107, particularly useful when the stationary
bicycle is used in a training environment, the stationary bicycle
is ready for use. Step 107 is typically achieved if an adjustment
fitting of the stationary bicycle was performed in a previous
session.
[0095] In step 108, a testing period is provided for the stationary
bicycle. More specifically, the user spins with the stationary
bicycle in order to provide a personal appreciation of the specific
selected dimensions. In step 108, the user or an operator (e.g., a
trainer) use the interface of the stationary bicycle control system
50 in order to adjust the seat and handlebar position, to reach
adjusted positions that are preferred by the user. It is also
pointed out that an observer, such as a bike-shop specialist, can
stand next to the user to provide comments on the stance and the
pedaling style.
[0096] In one testing configuration, the adjusted positions are
reached after several positions are tested. It is suggested to
provide incremental variations of the bicycle dimension, and
require that the user spins at a constant power. The comments of
the user are gathered at each variation of position, to facilitate
the selection of a bicycle size. It is also considered to film the
user while pedaling to provide footage of pedaling actuation for
different frame dimensions.
[0097] As shown in FIGS. 11 and 12, the camera system embodiment
can be used to collect real-time anthropomorphic data and provide
further refinement and adjustment to the component positions. The
data that could be collected includes joint angles, and relative
position in space (e.g., knee over toe) which can then be compared
to ideal positions for the desired performance, and result in
component position adjustment.
[0098] In another testing configuration, the adjusted positions are
used after gathering parameters related to the performance of the
user. More specifically, in optional step 109, measurements are
made on parameters related to the performance of the user of the
stationary bicycle. For instance, the pedaling power, the pedaling
cadence, and the heart rate of the user are measured as a function
of the stationary-bicycle dimensions. This step is typically
performed for high-level athletes. Further data could be collected
in the camera system embodiment for aerodynamic optimization based
on estimated aerodynamic drag determined by the rider's
position.
[0099] In step 110, once testing is completed and the user has
elected final dimensions for the stationary bicycle, the adjusted
dimensions are recorded for the user. Accordingly, if the
stationary bicycle is used in a training environment, a profile
specific to the user is recorded, so as to skip testing steps 108
and 109 at the next use.
[0100] In optional step 111, statistical data is recorded as a
function of the anthropometric data so as to accumulate general
data associating bicycle dimensions with anthropometric data. This
accumulated data can be used to better provide initial setup, as
well as real-time position optimization.
[0101] In step 112, particularly useful for bike-shop use,
bicycle-frame dimensions are suggested in accordance with the
adjusted positions recorded in step 110. In one embodiment, the
bicycle-frame dimensions may be compared with the inventory of a
shop, so as to determine as a function of the adjusted positions
resulting from method 100 what bicycles in the shop are suited for
the user. As an alternative embodiment, the bicycle-frame
dimensions obtained in step 112 are forwarded to a bicycle
manufacturer for the manufacture of a bicycle with such
dimensions.
[0102] As described above, method 100 is well suited for
determining an optimal bicycle size (combination of frame, stem,
spacer(s) and seat post) for a given rider. The bicycle-frame
dimensions of the determined optimal bicycle size may be compared
with inventory of a shop so as to determine a best fit complete
bicycle from available bicycles in the shop.
[0103] However, when custom fitting a bicycle to a given rider, it
is preferable to select each of the frame, stem, spacer(s), and
seat post separately, so that an optimal combination of components
can be determined. As used herein, selection or determination of a
spacer(s) includes the selection or determination of no spacer, or
one or more spacers.
[0104] To better accommodate custom fitting, the bicycle controller
system 50 includes a database 200 (see FIG. 5) for storing
dimensions of bicycle frames, stems, spacers, and seat posts that
are available for use, whether such availability is from shop
inventory of the shop doing the custom fitting, or from other
avenues of procurement, such as a manufacturer's inventory, or
inventory of another shop that participates in a parts-exchange
program. As discussed above, the information contained within
database 200 may be stored in an external database and accessed via
internet server 58.
[0105] The dimensions of the available bicycle frames are stored in
database 200 in a "cloud of points" format, best seen with
reference to FIGS. 7 and 8, where FIG. 7 depicts a one-line diagram
representation of a bicycle frame 300 having a top tube 302, a down
tube 304, a head tube 306, a seat tube 308, chain stay tubes 310,
and seat stay tubes 312, all disposed and attached to each other in
a manner known in the art, and FIG. 8 depicts an aggregate cloud of
points 400 (also herein referred to as a first cloud of points)
that represent the X, Y coordinates of the top of the head tube
402, and the X, Y coordinates of the top of the seat post 404,
relative to the central axis of the foot support 406, for all
frames 300 that are available to the custom fitter. The graphic
circles 314, 316 and 318 relate the features of frame 300 depicted
in FIG. 7 with the associated cloud of points 402 and 404 depicted
in FIG. 8. As can be seen from the illustration of FIG. 8, there is
only one X, Y coordinate for the foot support of each available
frame, as this X, Y coordinate in used as the reference discussed
above in connection with the center of the crank set 14. The
dimensions of the available stems and spacers, and the dimensions
of the available seat posts, are also stored in database 200 in a
respective cloud of points formats.
[0106] Although the invention has been herein described in what is
perceived to be the most practical and preferred embodiments, it is
to be understood that the invention is not intended to be limited
to the specific embodiments set forth above. Rather, it is
recognized that modifications may be made by one of skill in the
art of the invention without departing from the spirit or intent of
