Description
PRIORITY CLAIM
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 60/359,761 entitled "Striding Simulator",
filed on Feb. 26, 2002.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention generally relates to an improved
stationary exercise apparatus. Certain embodiments include
structures and methods for controlling foot articulation and/or the
shape and orientation of a path of a user's foot during foot motion
while the exercise apparatus is in use.
[0004] 2. Description of Related Art
[0005] Walking, striding, and/or jogging are popular forms of
outdoor exercise that provide both muscular and cardiovascular
benefit. Walking, striding, and/or jogging indoors, and in some
cases outdoors, may directly or indirectly stress joints (e.g.,
knees or ankles). Outdoor exercise may also prove to be difficult
due to environmental conditions such as inclement weather. An
exercise device for indoor use may need to provide a realistic
simulation of walking, striding, and/or jogging while limiting
stress on one or more joints of the body. Different indoor exercise
apparatus have been developed in attempts to provide an apparatus
that simulates walking, striding, and/or jogging movements for a
beneficial muscular and cardiovascular workout.
[0006] U.S. Pat. No. 3,316,898 to Brown, which is incorporated by
reference as if fully set forth herein, discloses an exercise
apparatus for exercising legs and hips of a user. The exercise
apparatus may move the legs of the user by power means. The
apparatus has a pair of parallel, reciprocating plates upon which
the feet of the user are placed. The apparatus may also have
adjustment means for changing the degree of reciprocation as
desired.
[0007] Miller U.S. Pat. Nos. 5,242,343 and 5,383,829, each of which
is incorporated by reference as if fully set forth herein, disclose
an exercise device that includes a pair of foot engaging links. The
first end of each link is supported for rotational motion about a
pivot axis and a second end of each link is guided in a reciprocal
path of travel. The combination of these foot link motions may
permit a foot of the user of the exercise device to travel in an
inclined, oval path.
[0008] Miller U.S. Pat. Nos. 5,518,473 and 5,755,642, each of which
is incorporated by reference as if fully set forth herein, disclose
an exercise device with a frame that supports a pair of foot links
so that a first end of each foot link is pivotably coupled to the
frame for motion about an arcuate path. A guide, which is supported
by the frame, engages each foot link and directs a second end of
each foot link along a closed, curved, generally teardrop shaped
path of travel. The combination of motions in the exercise device
defined by the foot link may provide a running and stepping motion
in which the heel of a user's foot initially rises faster than the
toe as the foot begins to move forward and in which the heel of the
user's foot subsequently falls faster than the toe as the foot
begins to move backwards.
[0009] Miller U.S. Pat. Nos. 5,577,985; 5,611,756; and 5,911,649,
each of which is incorporated by reference as if fully set forth
herein, disclose an exercise device that includes a frame having a
set of guide links pivotally supported on the frame. Each guide
link supports a foot engaging link at one end. The guide links may
be reciprocated back and forth by a set of intermediate links that
engage a set of cranks that rotate about a second pivot point. A
control link joins the foot link to the intermediate link and
operates to vary the angle between the guide links and the foot
links as the guide links reciprocate.
[0010] U.S. Pat. No. 6,045,487 to Miller, which is incorporated by
reference as if fully set forth herein, discloses an exercise
apparatus with a set of guide links pivotally supported on the
apparatus. Each guide link supports a foot link at one end. A
control member engages each foot link. The apparatus also includes
a reciprocating assembly that engages and reciprocates the control
members so as to move the associated foot links up and down as the
guide link pivots back and forth.
[0011] U.S. Pat. No. 6,398,695 to Miller, which is incorporated by
reference as if fully set forth herein, discloses an exercise
device with a frame having a pair of crank arms pivotally supported
on the frame. Each crank arm engages a drive link and each drive
link engages a guide member. A foot link is pivotally connected to
each guide member. A control link pivotally connects each foot link
to the drive link. During operation, the drive links and the crank
arms cooperate to cause the reciprocal motion of the guide members
and the control link operates to vary the angle between each foot
link and its associated guide member as the guide member
reciprocates.
[0012] U.S. Pat. No. 6,190,289 to Pyles et al., which is
incorporated by reference as if fully set forth herein, discloses a
foldable and transportable elliptical exercise machine. The
exercise machine includes pedal arms and optional corresponding
load bearing rails that are folded to an upright position for
storage and transportation.
[0013] Whan-Tong et al. U.S. Pat. Nos. 5,685,804 and 6,146,313,
each of which is incorporated by reference as if fully set forth
herein, disclose an exercise device with a pair of foot engaging
links. The rearward ends of the foot links are supported for
arcuate motion about a pivot axis. The forward ends of the foot
links travel back and forth along a guide. The combination of these
two link motions permits a user's feet to travel along an
elliptical path. The inclination of the foot links may be
selectively altered to vary the nature of the stepping motion
experienced by the user.
[0014] U.S. Pat. No. 6,123,650 to Birrell, which is incorporated by
reference as if fully set forth herein, discloses an exerciser with
a floor engaging frame and a forward upright post structure. Near
the rear of the frame are attached left and right axle mount
supports that house a transverse axle. The axle is bifurcated to
allow the two halves to rotate independently and connect the left
and right drive wheels, respectively. Left and right foot link
members rollably engage the drive wheels at the link member's rear
end portions. The forward end portions of the foot link members
rollably engage left and right inclinable guide ramps. The
inclinable guide ramps are biased rotationally upwardly by biasing
members (e.g. springs) to resist downward forces. Left and right
foot support portions are mounted on the foot link members. As the
foot link members reciprocate forwardly and rearwardly along the
inclinable guide ramps, the interaction of the oscillating weight
of a running or walking user, together with the independently
upwardly biased inclinable guide ramps, causes the foot support
portions to travel along an elliptical path.

reciprocating pedal up to a predetermined velocity. In this manner,
the exercise workout may be more natural since the user only has to
expend energy normally associated with walking or running and not
the operation of the apparatus.
SUMMARY
[0026] In an embodiment, an exercise apparatus includes a frame and
one or more movable members. One or more rollers may be coupled to
the frame. The movable members may engage the rollers such that the
movable members may move translatably along the rollers during use
of the exercise apparatus by a user. The exercise apparatus may
include a crank system. Ends of the movable members may be coupled
to the crank system. The ends of the movable members may move in a
substantially orbital path about a crankshaft axis of the crank
system. The exercise apparatus may further include pivotal linkage
assemblies that orient the feet of a user of the apparatus during
operation of the apparatus by the user. The feet of the user may
follow a closed path during operation of the apparatus. In some
embodiments, a closed path of each foot of the user may be a
substantially elliptical path. In certain embodiments, a closed
path of each foot of the user is relatively pointed at one end.
[0027] In certain embodiments, the foot of the user may be
controllably oriented in the closed path by a pivotal linkage
assembly. A pivotal linkage assembly may provide a selected
articulation to a user's foot during motion of the user's foot in a
closed path. In certain embodiments, the pivotal linkage assembly
provides a selected articulation to the user's foot during rearward
motion of the user's foot in the closed path. In one embodiment,
the pivotal linkage assembly causes the user's heel to rise
relative to the user's toe during rearward motion of the user's
foot in the closed path. In other embodiments, the pivotal linkage
assembly may cause the user's heel to fall relative to the user's
toe during rearward motion of the user's foot in the closed path.
In yet other embodiments, the pivotal linkage assembly may cause
the user's heel to remain at substantially the same height as the
user's toe during rearward motion of the user's foot in the closed
path.
[0028] In certain embodiments, a pivotal linkage assembly includes
a foot member and/or a pivotal member. A foot member may be coupled
to a movable member at a selected point on the movable member. The
selected point on the movable member may be adjusted to control the
shape of the closed path of the foot of the user. In an embodiment,
the selected point on the movable member is selected so that the
shape of the closed path of the user's foot simulates walking,
striding, and/or jogging motion during operation of the
apparatus.
[0029] A pivotal member may be coupled to a foot member proximate
one end of the foot member. In certain embodiments, a point of
coupling between the pivotal member and the foot member may move in
an arcuate path. The pivotal member may be coupled to the frame at
a selected point on the pivotal member. In an embodiment, the
selected point on the pivotal member coincides with the center of
the arcuate path of the point of coupling between the pivotal
member and the foot member.

DETAILED DESCRIPTION
[0038] Turning to the drawings, FIG. 1 depicts an elevation drawing
of an embodiment of exercise apparatus 100. FIG. 2 depicts a plan
view of the embodiment of exercise apparatus 100 depicted in FIG.
1. Exercise apparatus 100 may include frame 101. Frame 101 may
include a base portion and one or more upper appendages coupled to
the base portion. In some embodiments, the base portion and the
upper appendages may be portions of one continuous piece that forms
frame 101. In other embodiments, the base portion and the upper
appendages may be separate pieces coupled together (e.g., welded or
bolted) to form frame 101. Generally, frame 101 is a single unit
constructed from one or more pieces that can support the weight and
movement of a user on exercise apparatus 100. Frame 101 may be
placed on the floor or on the ground.
[0039] In an embodiment, a crank system is coupled to frame 101.
The crank system may include both right and left crank members 102.
Crank members 102 may be coupled to crankshaft 107. Crankshaft 107
may be coupled to the crank system on a crankshaft axis of the
crank system. The crankshaft axis may pass through the center of
crankshaft 107. Crankshaft 107 may be coupled to frame 101. One or
more bearings may be used at the coupling of crankshaft 107 and
frame 101. The bearings may be used to support crankshaft 107 on
frame 101. Crank members 102 may rotate about the crankshaft axis
of the crank system during use of exercise apparatus 100.
[0040] Pulley 114 may be coupled to crankshaft 107. Pulley 114 may
rotate with crankshaft 107 during use of exercise apparatus 100.
Pulley 114 may be coupled to brake device 104 with belt 113. In an
embodiment, brake device 104 may be a brake/inertia device. In
certain embodiments, brake device 104 is coupled to pulley 114 such
that rotation of the brake device causes orbital motion of crank
members 102 or orbital motion of crank members 102 causes rotation
of the brake device. Brake device 104 may operate as is well known
in the art to increase or decrease the load on pulley 114 so that
the workload of a user of exercise apparatus 100 increases or
decreases accordingly.
[0041] Crank members 102 may be coupled to movable members 105 at
couplings 115. In certain embodiments, movable members 105 include
orbital portions 124. Orbital portions 124 may be coupled to crank
members 102 at couplings 115. During use of exercise apparatus 100,
ends of movable members 105 or ends of orbital portions 124 coupled
to crank members 102 may move in a substantially orbital path
around crankshaft 107 and the crankshaft axis of the crank system.
The substantially orbital path of the ends of movable members 105
may include, but is not limited to, a circular path, an elliptical
path, or any other substantially orbital path around the crankshaft
axis. In an embodiment, couplings 115 are pivotal couplings. In
other embodiments, couplings 115 may be other types of couplings
such as, but not limited to, a scotch yoke, a multi-bar linkage, or
other types of multi-component connection methods that produce a
substantially orbital path for the ends of movable members 105
about the crankshaft axis. In some embodiments, a position of
couplings 115 may be variable or adjustable. For example, there may
be multiple positions for couplings 115 on crank members 102 or a
servo controller may move the position of couplings 115 on crank
members 102.
[0042] In one embodiment, movable members 105 may have a bent shape
with one bend, as shown in FIG. 1. A shape of movable members 105,
however, is not limited to the shape shown in FIG. 1. Other
embodiments of movable members 105 may have more than one bend or
no bends. For example, a movable member may have a gradually curved
shape, may be straight, or may include a combination of sections
and/or shapes as desired by a designer, builder, or user of
exercise apparatus 100. In FIGS. 1 and 2, movable members 105 have
orbital portions 124 and distal portions 125. Orbital portions 124
are the portions of movable members 105 proximate the crank system.
Distal portions 125 may be portions of movable members 105 distal
from the crank system.
[0043] Movable members 105 or distal portions 125 may be
translatably coupled to frame 101. In an embodiment, movable
members 105 are translatably coupled to one or more rollers 109
coupled to frame 101. Rollers 109 may be fixably coupled to frame
101 such that the rollers are free to rotate, but the axis of the
roller does not change position relative to the frame 101. In an
embodiment, first movable member 105 is translatably coupled to a
first roller 109 and a second movable member 105 is translatably
coupled to a second roller 109. Coupling individual movable members
105 to individual rollers 109 may allow for independent motion of
the movable members along the rollers (e.g., a first movable member
may be moving in the forward direction while a second movable
member is moving in the rearward direction on exercise apparatus
100). Movable members 105 may translatably move along rollers 109
(e.g., in a back and forth motion along the rollers). In some
embodiments, rollers 109 may provide support for movable members
105. In certain embodiments, a point of coupling between rollers
109 and frame 101 may be a substantial weight-bearing point for
exercise apparatus 100 (i.e., the point of coupling supports a
substantial portion of the weight of a user of the exercise
apparatus). Having rollers 109 support a substantial portion of the
weight of the user may improve reliability and durability of
exercise apparatus 100. Transferring the weight of the user through
the rollers to the frame rather than through other joints (e.g.,
pivotal joints) may reduce stresses on and deflection of these
other joints.
[0044] One or more pivotal linkage assemblies may be coupled to
movable members 105 and/or frame 101. The pivotal linkage
assemblies may be coupled to movable members 105 and frame 101 at
couplings 121 and couplings 112, respectively. The pivotal linkage
assemblies may include foot members 123 and pivotal members 110, as
shown in FIGS. 1 and 2. In certain embodiments, a length of foot
members 123 is substantially flat. Foot members 123 may be foot
platforms for the user's feet. Foot members 123 and/or pivotal
members 110 may include shapes other than those shown in FIG. 1.
For example, foot members 123 and/or pivotal members 110 may be
curved, straight, or a combination of sections and/or shapes as
desired by a designer, builder, or user of exercise apparatus 100.
Foot members 123 may include foot plates 106. Foot plates 106 may
engage feet of a user of exercise apparatus 100. In some
embodiments, foot plates 106 may be adjustable on foot members 123.
For example, foot plates 106 may be placeable at one or more angles
and/or one or more locations on foot members 123. Foot members 123
and pivotal members 110 may be coupled at couplings 122. In certain
embodiments, pivotal members 110 are arm members or arm linkage
members. Pivotal members 110 may be coupled to frame 101 at
couplings 112. In an embodiment, foot members 123 are coupled to
movable members 105 at couplings 121. Couplings 112, 121, and/or
122 may be pivotal couplings or any other suitable types of
couplings.
[0045] A user may engage the exercise apparatus by placing the
user's feet on foot plates 106. The user may also grasp or hold
pivotal members 110. The user may grasp or hold upper portions 128
of pivotal members 110. To begin exercise on exercise apparatus
100, the user may initiate a walking, striding, or jogging motion
with the user's feet on foot plates 106 and/or the user's hands and
arms grasping pivotal members 110. The components of exercise
apparatus 100 described herein may work in unison to provide motion
for the user that follows a foot path simulating walking, striding,
or jogging and may include arm or upper body motion during the
simulation of walking, striding, or jogging. As the user's foot
moves through the foot path, the pivotal linkage assemblies (i.e.,
foot members 123) may cause movable members 105, or distal portions
125, to translate along rollers 109 in a back and forth motion.
During movement of movable members 105, the ends of the movable
members (i.e., orbital portions 124) coupled to crank members 102
may move in the substantially orbital path about the crankshaft
axis of the crank system.
[0046] During user exercise, the pivotal linkage assemblies, which
include foot members 123 and/or pivotal members 110, may orient the
feet of the user so that the feet move in a prescribed path.
Couplings 121 may follow path 131 during use of exercise apparatus
100, as shown in FIG. 1. Thus, the feet of the user may follow path
131 during use of exercise apparatus 100. A detailed view of path
131 is shown in FIG. 1A. Path 131 may be a closed path. In some
embodiments, path 131 may be a substantially elliptical path. A
substantially elliptical path may be defined, in embodiments
described herein, as a closed path with major and minor axes. Path
131 may be relatively pointed at one end (e.g., front end or rear
end) of the path. In certain embodiments, path 131 is a
substantially elliptical path with a relatively pointed front end,
as shown in FIG. 1A. Path 131 may be divided into approximately
four quadrants by major axis 142 and minor axis 141. Major axis 142
may be oriented generally lengthwise in path 131 and minor axis 141
may be oriented generally perpendicularly to the major axis. Minor
axis 141 may intersect major axis 142 at, or about at, a midpoint
of the major axis.
[0047] An orientation of major axis 142 relative to the ground is
referenced by the angle "a" in FIG. 1A. A magnitude of angle "a"
may be controlled by the shape of movable member 105 and/or a
height of roller 109 relative to frame 101. Angle "b", as shown in
FIG. 1, may represent the relative angle between distal portion 125
and orbital portion 124 of movable member 105. Generally, an
increase in angle "b" increases angle "a". Increasing the height of
roller 109 relative to frame 101 also generally increases angle
"a". Thus, a designer, builder, or user of exercise apparatus 100
may select or adjust angle "b" and/or the height of one or more
rollers 109 relative to frame 101 to control the orientation of
path 131 relative to the ground.
[0048] In certain embodiments, a designer, builder, or user of
exercise apparatus 100 may control the shape of path 131 by
adjusting the geometry of linkages in the exercise apparatus. FIG.
3A depicts a schematic of the embodiment of the linkage geometry of
exercise apparatus 100, as shown in FIGS. 1 and 2. FIG. 3B depicts
a schematic of an embodiment of linkage geometry that has been
modified from the embodiment of FIG. 3A. In FIG. 3A, "x" denotes a
distance between coupling 115 and coupling 121. In FIG. 3B, the
distance between coupling 115 and coupling 121 has been reduced and
is denoted by "x'". Reducing the distance between coupling 115 and
coupling 121 generally produces a more rounded path 131, as shown
in FIG. 3B compared to FIG. 3A. Thus, the geometry of exercise
apparatus 100 (e.g., the distance between coupling 115 and coupling
121) may be adjusted to produce a selected shape of path 131. In
certain embodiments, the distance between coupling 115 and coupling
121 is adjusted by selecting the point or location of coupling 121
on movable member 105.
[0049] In certain embodiments, a designer, builder, or user of may
adjust the geometry of exercise apparatus 100 to control foot
articulation during use of the exercise apparatus. The geometry of
exercise apparatus 100 may be adjusted to control the articulation
of foot plates 106, thus providing articulation to the user's feet.
Foot articulation may be defined as the relative angle or
orientation of the foot (i.e., relative position of the toe versus
the heel of the foot) during foot motion. In certain embodiments,
foot articulation is controlled during movement of the user's feet
through one or more portions of path 131.
[0050] In an embodiment, foot articulation may be controlled by the
geometry of a pivotal linkage assembly (i.e., the geometry of foot
member 123 and/or pivotal member 110). FIG. 4A depicts a schematic
of the embodiment of the effect of exercise apparatus 100 linkage
geometry, as shown in FIGS. 1 and 2, on foot articulation. Arc "A"
with center "C" and radius "R" may be created in space such that
arc "A" drops away from the lower quadrants of path 131 (i.e., the
lower quadrants of path 131 shown in FIG. 1A). Arc "A" is created
so that arc "A" passes through coupling 121 at the front end of
path 131, as shown in FIG. 4A. Center "C" and radius "R" of arc "A"
may then be transposed forward so that center "C" coincides with
coupling 112 on frame 101. This transposition of center "C" and
radius "R" defines a corresponding geometry for pivotal member 110
and foot member 123. Thus, coupling 122 will follow an arcuate path
the same shape and orientation as arc "A". As shown in FIG. 4A,
during rearward motion of foot member 123 (i.e., the lower portion
of path 131), coupling 121 falls slower, as shown by the lower
portion of path 131, than coupling 122, as shown by arc "A", and
the user's heel will rise relative to the user's toe during
rearward motion of the foot. In certain embodiments, the user's
heel may rise relative to the user's toe during portions of the
rearward motion of the foot. For example, the user's heel may rise
relative to the user's toe during an approximately front lower
quarter of path 131 (i.e., the front lower quadrant shown in FIG.
1A).
[0051] In an embodiment, the geometry of exercise apparatus 100 may
be adjusted so that the user's heel remains at a substantially
similar height as the user's toe during rearward motion of the
foot. FIG. 4B depicts a schematic of an embodiment of an effect of
exercise apparatus 100 linkage geometry on foot articulation such
that the user's heel remains at a substantially similar height as
the user's toe during rearward motion of the foot. Arc "A'" with
center "C'" and radius "R'" may be created in space such that arc
A' generally coincides with the lower quadrants of path 131 (i.e.,
the lower quadrants of path 131 shown in FIG. 1A). Arc A' is
created so that arc A' passes through coupling 121 at the front end
of path 131, as shown in FIG. 4B. Center C' and radius R' of arc A'
may then be transposed forward so that center C' coincides with
coupling 112 on frame 101. This transposition of center C' and
radius R' defines a corresponding geometry for pivotal member 110
and foot member 123. Thus, coupling 122 will follow an arcuate path
the same shape and orientation as arc A'. As shown in FIG. 4B,
during rearward motion of foot member 123 (i.e., the lower portion
of path 131), coupling 121 falls at substantially the same rate, as
shown by the lower portion of path 131, as coupling 122, as shown
by arc A', and the user's heel will remain at the substantially
same height as the user's toe during rearward motion of the foot.
In certain embodiments, the user's heel may remain at the
substantially same height as the user's toe during portions of the
rearward motion of the foot. For example, the user's heel may
remain at the substantially same height as the user's toe during an
approximately front lower quarter of path 131 (i.e., the front
lower quadrant shown in FIG. 1A).
[0052] In an embodiment, the geometry of exercise apparatus 100 may
be adjusted so that the user's heel falls at a faster rate than the
user's toe during rearward motion of the foot. FIG. 4C depicts a
schematic of an embodiment of an effect of exercise apparatus 100
linkage geometry on foot articulation such that the user's heel
falls at a faster rate than the user's toe during rearward motion
of the foot. Arc A" with center C" and radius R" may be created in
space such that arc A" rises relative to the lower quadrants of
path 131 (i.e., the lower quadrants of path 131 shown in FIG. 1A).
Arc A" is created so that arc A" passes through coupling 121 at the
front end of path 131, as shown in FIG. 4C. Center C" and radius R"
of arc A" may then be transposed forward so that center C"
coincides with coupling 112 on frame 101. This transposition of
center C" and radius R" defines a corresponding geometry for
pivotal member 110 and foot member 123. Thus, coupling 122 will
follow an arcuate path the same shape and orientation as arc A". As
shown in FIG. 4C, during rearward motion of foot member 123 (i.e.,
the lower portion of path 131), coupling 121 falls at a faster
rate, as shown by the lower portion of path 131, than coupling 122,
as shown by arc A', and the user's heel will fall relative to the
user's toe during rearward motion of the foot. In certain
embodiments, the user's heel may fall relative to the user's toe
during portions of the rearward motion of the foot. For example,
the user's heel may fall relative to the user's toe during an
approximately front lower quarter of path 131 (i.e., the front
lower quadrant shown in FIG. 1A).
[0053] In some embodiments, a pivotal linkage assembly may include
one or more components other than foot member 123 and pivotal
member 110. These components may be additional components in the
pivotal linkage assembly or components used in lieu of foot member
123 and/or pivotal member 110. These components may be designed so
that the components alone, or in combination with foot member 123
and/or pivotal member 110, can be used to control foot articulation
in exercise apparatus 100 as described herein.
[0054] As shown in the embodiments described above, a designer,
builder, or user of exercise apparatus 100 may advantageously be
able to selectively control desired parameters (e.g., a shape of
path 131, an orientation of path 131, and/or foot articulation) of
the exercise apparatus by controlling the geometry of the exercise
apparatus. Selectively controlling these desired parameters may
allow a designer, builder, or user of exercise apparatus 100 to
better simulate foot and/or body patterns involved with walking,
striding, and/or jogging. Improved simulation of these patterns may
make an exercise apparatus more comfortable for a user to exercise
with and less stressful on joints in the body. The improved
simulation exercise apparatus may provide a better cardiovascular
workout experience for the user.
[0055] In some embodiments, a user, technician, or trainer may
adjust parameters described above (i.e., a shape of path 131, an
orientation of path 131, and/or foot articulation) after exercise
apparatus 100 has been designed and constructed. These parameters
may be adjusted by allowing the location of any one of the
couplings (e.g., couplings 112, 121, and/or 122) and/or the height
of one or more rollers 109 relative to frame 101 to be adjusted.
For example, a pin may fix the location of coupling 121 on movable
member 105. Movable member 105 may include one or more holes to
allow the pin to fix the location of coupling 121 at any one of the
hole positions. A user, technician, or trainer may be allowed to
remove the pin, adjust the location of coupling 121, and replace
the pin to reaffix the position of coupling 121 at the new
location.
[0056] FIG. 5 depicts an elevation drawing of an alternative
embodiment of exercise apparatus 100. Movable member 105 may be
coupled to pivotal member 110 with block 111. In an embodiment,
block 111 is a pivotal slider block. Block 111 may pivot at point
113 and allow pivotal member 110 to slide in a bore of block 111.
In the embodiment depicted in FIG. 5, foot plates 106 are placed on
movable members 105. Foot plates 106 may move in a closed path as
described herein.
