Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of United States
Provisional Application No. 60/489,946, filed Jul. 22, 2003 the
contents of which are incorporated by reference herein in their
entirety.
BACKGROUND OF THE INVENTION
[0002] The invention relates generally to exercise equipment and in
particular to an aquatic exercise bicycle for providing exercise in
a liquid medium. More particularly, the invention relates to an
aquatic exercise bicycle that may be adjusted and ridden in a
recumbent or upright bicycle configurations.
[0003] The benefits of aerobic exercise and particularly jogging
are well known. Jogging is not suggested for persons who are prone
to back, knee, and foot problems because the inherent impact of the
feet on the ground surface is often the cause of peripheral
vascular insufficiency or injury to the legs, ankles, and back.
Invalids, osteoarthritic, and postoperative patients are given
alternative forms of exercise such as swimming, which does not
necessarily exercise the muscles which come into play in running or
jogging.
[0004] Aquatic exercise, and jogging apparatus are known in the
art. There are several patents which disclose devices which are
used for exercising in water, and jogging devices used out of water
(i.e., treadmills). For example, one device for exercising in water
includes U.S. Pat. No. 5,665,039 to Wasserman et al., which
disclose an upright exercycle fixedly attached to a walkway of the
pool. However, this design is limited to adjustment of the seat
relative to the fixed crank and directed toward exercising in an
upright position only. This design does not allow an operator to
pedal the exercycle in a supine position as in a recumbent bicycle
configuration. The advantage of a stationary recumbent bicycle as
opposed to a stationary upright bicycle is that the user is
positioned in a sitting position with the legs extending forwardly
which reduces strain and stress on the spine and back muscles.
[0005] Current exercise bicycles can be classified into three
categories; (1) common bicycle held stationary while applying
resistance to the rear wheel, (2) sitting exercise bicycles, and
(3) semi-recumbent exercise bicycles. Units of the bicycle type are
typically used by persons who want to simulate outdoor cycling for
training purposes. With this form of exercise bicycle the weight of
a user may be supported by both a handlebar and a seat. The sitting
type refers to exercise bicycles where the user's weight is
substantially supported by a seat and the crank and pedals are
positioned below and shortly forward of the user. The
semi-recumbent type refers to exercise bicycles where the user's
weight is substantially supported by a seat and possibly a seat
back. The crank and pedals are positioned substantially forward of
the user on a substantially equal level with the seat.
[0006] Each type of exercise exercises somewhat different muscle
groups. The different configurations of exercise bicycles also
provide differing levels of comfort for each user. For example, the
classical position of a machine of the bicycle type provides the
realistic body position and motion that are essential for accurate
simulation of outdoor cycling. The classical position, however, may
require a significant portion of the user's weight to be supported
by the arms and upper body of the user. Such a position may be
uncomfortable for an elderly user.
[0007] Accordingly, it would be an advancement in the field to
provide an exercise bicycle on which a user is able to accurately
simulate the classical cycling position, while also allowing for an
alternate semi-recumbent position. Such a bicycle would increase
the range of users of differing abilities that may efficiently
exercise with a single bicycle. Additionally, such a bicycle usable
in a liquid medium, such as a swimming pool, would provide a
variety of workouts for a user, thus, promoting interest and
provide a method for exercising different muscle groups, while
limiting harmful impact on the user because of buoyancy provided by
the liquid medium. Furthermore, there is a desire for such an
aquatic exercise bicycle to be easily disposed and positioned
within the liquid medium, while remaining stable during
operation.
BRIEF SUMMARY OF THE INVENTION
[0008] The above discussed and other drawbacks and deficiencies are
overcome or alleviated by an aquatic exercise cycle that includes a
frame receptive to be at least partially submersed in a liquid
medium; a seat adjustably secured to the frame; a pair of handles
operably coupled to at least one of the frame and the seat for an
operator to hold onto; a crank assembly operably coupled to said
frame having an input shaft rotatable with a pair of user operated
pedals; and a variable resistance mechanism in operable
communication with the input shaft and receptive to varying a
resistance of rotation of the input shaft. The aquatic exercise
cycle allows the user to adjust at least the seat relative to the
crank assembly to select either an upright riding position or a
recumbent riding position. In an exemplary embodiment, the seat and
the crank assembly are adjustable relative to the frame to select
either an upright riding position or a recumbent riding
position.

present invention will be appreciated and understood by those

DETAILED DESCRIPTION
[0023] FIG. 1 is a side view of an aquatic exercise bicycle 10 in
an embodiment of the invention. The aquatic exercise bicycle 10
includes a frame 12 having a seat 14 operably coupled to frame 12
via a seat post 24, recumbent handles 16 operably connected to
either the seat 14 or seat post 15, upright handles 18 extending
from frame 12, and a crank assembly 20 secured to frame 12. Frame
12 is configure as a singular tube frame having an arch shape,
however, other suitable configurations are contemplated suitable to
the desired end purpose. Frame 12 includes feet 22 extending from
ends 23 defining frame 12 to stabilize the aquatic exercise bicycle
10. The entire aquatic exercise bicycle 10, or at least a
substantial portion thereof, is intended to be immersed in water,
such as a swimming pool, for example, when in operation. A user
operates pedals 21 extending from cranks 19 operably connected to
an input shaft (not shown).
[0024] Seat 14 is mounted on seat post 24 that rides in a slot 26
configured in a track 28 depending from frame 12. A knob having a
threaded fastener generally shown at 27 secures the post 24 in a
fixed location relative to track 28. Tilt of the seat 14 may be
adjusted using a same knob or a separate further knob. In FIG. 1,
seat 14 is shown in the recumbent position.
[0025] Although track 28 is shown and described as depending from
frame 12, it will be recognized that track 28 having a slot 26 may
be configured in frame 12. In either case, slot 26 provides
infinite adjustment for translation of seat 14 via seat post 24
substantially parallel with frame 12 within the bounds of slot 26.
Alternatively, it is also contemplated that slot 26 may be
substituted with a plurality of discrete slots or apertures 26
along a length of track 28 or frame 12 providing discrete
adjustability for seat 14 via seat post 24. In this manner, seat 14
may be translated relative to frame 12 and crank assembly 20 to
select either an upright or a recumbent riding position depending
on the relative location of seat 14 with respect to crank assembly
20.
[0026] In an exemplary embodiment, crank assembly 20 is secured to
frame 12 through two supports 30 and 32. Support 30 is pivotally
connected to frame 12 and to a housing 31 of the crank assembly 20.
Support 32 is pivotally connected to housing 31 of crank assembly
20 at one end. The other end of support 32 rides in a slot 34
configured in a track 36 depending from frame 12 forward of track
28. A knob having a threaded fastener generally shown at 38 secures
support 32 relative to track 36. In FIG. 1, the crank assembly 20
is shown in the recumbent position.
[0027] Although track 36 is shown and described as depending from
frame 12, it will be recognized that track 36 having a slot 34 may
be configured in frame 12. In either case, slot 34 provides
infinite adjustment for translation of one end of support 32
substantially parallel with frame 12 within the bounds of slot 34.
Alternatively, it is also contemplated that slot 34 may be
substituted with a plurality of discrete slots or apertures 34
along a length of track 36 or frame 12 providing discrete
adjustability for support 32. In this manner, crank assembly 20 may
be positioned relative to frame 12 and crank assembly 20 to select
either an upright or a recumbent riding position depending on the
relative location of seat 14 with respect to crank assembly 20.
[0028] It will be recognized by one skilled in the pertinent art
that although a pin and slot arrangement have been described with
reference to translation of one end of support 32 and seat 14 via
seat post 24, any suitable connection is contemplated that allows
such translation or positioning of seat 14 relative crank assembly
20. For example, crank assembly 20 may be supported via a single
support 32 absent support 30. In this example, crank assembly 20 is
pivotally attached to frame 12 at a first location and a second
location. The crank assembly is attached to the first location
using support 32 having a first end pivotally extending from the
crank assembly 20 and an opposite second end realeasably coupled
along a length of frame 12 at the first location depending on a
selected riding position. Here the second location may include one
end of housing 31 pivotally attached to frame 12 allowing use of a
single support 32 to pivotally translate input shaft generally
shown at 50 in FIGS. 1 and 2 about the second location
corresponding to direct pivotal attachment of housing 31 at an
opposite end to frame 12 coincident with the second location.
[0029] FIG. 2 shows the aquatic exercise bicycle 10 of FIG. 1 in
the upright position with the recumbent handles 16 removed. Seat 14
has been moved towards upright handles 18 via movement of seat post
24 in track 28. Support 32 has been moved toward seat 14 in track
36. Thus, seat 14 is positioned substantially directly over the
crank assembly 20 for the upright riding position.
[0030] FIGS. 3-5 are various perspective views of the aquatic
exercise bicycle 10 in both the upright and recumbent riding
positions. FIGS. 3 and 4 illustrate a further knob 51 in
conjunction with handles 18 for raising and lowering the handles,
as known in the pertinent art.
[0031] FIG. 6 depicts an exemplary variable resistance mechanism
that may be incorporated in the crank assembly 20. Pedals 21 are
mechanical coupled to gears 42 and 44 which when operated, pump
fluid from an inlet 46 to an outlet 48. It is envisioned that input
shaft 51 (FIGS. 1 and 2) may be operably connected to one of the
gears 42 and 44 via a corresponding shaft extending through one of
the gears 42 and 44 via a transmission means, such as a belt or
chain, for example, but not limited thereto. A handle 50 is
attached to a restrictor plate 52 by a threaded shank 54. As handle
50 is turned, restrictor plate 52 is moved into and out of outlet
48. This provides adjustable resistance and approaches an infinite
resistance as outlet 48 becomes completely blocked. The fluid
circulated by gears 42 and 44 may be the fluid in which the aquatic
exercise bicycle 10 is immersed or may be a self contained closed
fluid system with appropriate reservoirs.
[0032] FIGS. 7-14 depict alternative mechanisms for generating
variable resistance. Each mechanism includes an input shaft, which
is operably coupled to both pedals 21 and an output shaft coupled
to one of gears 42 or 44. By adjusting the speed of the output
shaft relative to the input shaft, the resistance is either
increased or decreased. In some instances, the input shaft may
coincide with input shaft 51 depicted in FIGS. 1 and 2, as will be
described hereinafter.
[0033] Shown in FIGS. 7A and 7B is a pair of split pulleys 100
coupled by a belt 102. Each split pulley 100 includes two pulley
halves 101. Each pulley half 101 has a beveled interior surface 104
as best seen with reference to FIG. 8 illustrating a pulley half
101 in cross-section. The spacing 106 between pulley halves 101 may
be adjusted by the user (e.g., through a knob mechanically coupled
to one or both pulley halves). By moving the pulley halves 101
closer or farther apart, the effective diameter of the pulley 100
relative to the belt 102 is changed to alter the output speed of an
output shaft 108. FIG. 7A illustrates a high output speed at output
shaft 106 and thus more resistance felt at input shaft 51. FIG. 7B
illustrates a low output speed at output shaft 106 and thus less
resistance felt at input shat 51.
[0034] FIG. 9 shows an alternative mechanism for changing
resistance. An input wheel 110 is in contact with an output disk
112. The location of the input wheel 110 relative to the output
disk 112 may be altered by the user (e.g., by a knob mechanically
coupled to the input wheel shaft 114). The radial location of the
input wheel 110 relative to the output disk 112 establishes the
speed with which the output disk 112 rotates. In other words, as
input wheel 110 is translated from a center portion to a peripheral
portion defining output disc 112, input wheel 110 and thus input
wheel shaft 114 rotate faster. Furthermore, there is less
resistance felt by input wheel shaft 114 to rotate output disc 112
as input wheel 110 is translated from a center portion to a
peripheral portion defining output disc 112.
[0035] FIG. 10 shows an alternative mechanism for changing
resistance. An input wheel 120 is in contact with an output cone
122. The location of the input wheel 120 relative to the output
cone 122 may be altered by the user (e.g., by a knob mechanically
coupled to the input wheel shaft 124). The location of the input
wheel 120 relative to the output cone 122 establishes the speed
with which the output cone 122 rotates. In other words, as input
wheel 120 is translated from a tip portion to a larger diameter
base portion defining output cone 122, input wheel 120 and thus
input wheel shaft 124 rotate faster. Furthermore, there is less
resistance felt by input wheel shaft 124 to rotate output cone 122
as input wheel 120 is translated from the tip portion to the larger
diameter base portion defining output cone 122.
[0036] FIGS. 11 and 12 depict alternative mechanisms for changing
resistance. Counter rotating input wheels 130 are in contact with
two output disks 132. The distance between the pair of input wheels
130 may be altered by the user (e.g., by a knob mechanically
coupled to one or both output disks). As the pair of input wheels
130 are brought closer together, friction on the output disks 132
increases because of the parabolic configuration on facing surfaces
of the output dicks 132, thereby reducing speed of the output disks
132 and increasing a resistance felt by an input shaft (not shown)
operably connected to the input wheels 130.
[0037] FIGS. 13 and 14 depict an alternative mechanism for changing
resistance. An input shaft 140 is connected to a driving cone 142.
The driving cone 142 contacts an output disk 144 coupled to an
output shaft 146. The location of the input shaft 140 relative to
the output shaft 146 may be altered by the user (e.g., by a knob
mechanically coupled to one or both of the input shaft and output
shaft). The location of the input shaft 140 relative to the output
shaft 146 establishes the speed with which the output shaft 146
rotates. In FIG. 13, the input shaft 140 and output shaft 146 are
substantially aligned resulting in a higher output speed and less
resistance felt by input shaft 140 as more driving cone 142 is in
contact with the output disk 144. In FIG. 14, the input shaft 140
is displaced from the output shaft 146 resulting in a lower output
shaft speed and higher resistance felt at input shaft 140.
[0038] Although numerous variable resistance mechanisms have been
described with reference to FIGS. 6-14 to provide a variable
resistance on input shaft 51 felt by a user, any number of variable
resistance mechanisms known in the art are contemplated for use
suitable to the desired end purpose. In any selected variable
resistance mechanism, such mechanism should not interfere with
selection and operation of the aquatic exercise cycle in the
upright or recumbent riding positions. Furthermore, such a selected
mechanism should allow easy disposal and positioning of the aquatic
exercise cycle within the liquid medium such as a swimming pool,
for example, while remaining stable during operation thereof and
without having to attach the cycle to swimming pool structure.
[0039] One of the advantages obtained by using above described
aquatic exercise cycle is discussed below. Amateur tri-athletes,
like professionals will train from about 15 hours per week up to
about 30 hours per week in an effort to maximize their performance
in each of the three triathlon disciplines: swimming, cycling, and
running. Three of the key factors that comprise a successful
training program for this type of event are the hours of quality
effort invested, the maximum recovery benefit obtained between
training sessions, and remaining injury-free during the training
program.
[0040] One alternative course of training which can achieve all
three of the above includes cross-training with aquatic exercise
equipment, including the above described aquatic exercise cycle.
For instance, using a high quality, non-motorized aquatic treadmill
and an aquatic exercise cycle in a small pool with a tethered or
mechanical swim resistance device will greatly reduce the amount of
time required to produce the same benefit from land-based
training.
[0041] Very few athletes are able to devote equal training time to
each discipline because they are stronger in one or two than the
third, and need to devote additional time to that third or weaker
area. However, devoting additional time to the weaker discipline
takes valuable hours away from the other disciplines, which can
then suffer.
[0042] One solution includes aquatic training because training in
water produces 12 times more resistance than training in air(i.e.,
on land) and the time required to achieve equal benefit is greatly
reduced. Simultaneously, the buoyancy obtained by training in water
greatly reduces stress and impact on joints, bones, and muscles.
This benefit not only reduces the likelihood of injury, but also
reduces the recovery time required between training sessions. In
addition, subsequent training sessions are of higher quality
because the lingering fatigue factor and discomfort level caused by
previous sessions is greatly reduced.
[0043] Thus, using the above described aquatic exercise cycle in a
liquid medium that allows selection between a classical upright and
recumbent riding position can aid in triathlon training, at least
with respect to training for a bicycling aspect thereof.
[0044] While this invention has been described with reference to a
preferred embodiment, it will be understood by those skilled in the
art that various changes may be made and equivalents may be
substituted for elements thereof without departing from the scope
of the invention. In addition, many modifications may be made to
adapt a particular situation or material to the teachings of the
invention without departing from the essential scope thereof.
Therefore, it is intended that the invention not be limited to the
particular embodiment disclosed as the best mode contemplated for
carrying out this invention.
