DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS
[0020] FIGS. 1-3 schematically illustrate an exercise device 20
according to an example embodiment. FIGS. 1 and 2 illustrate
exercise device 20 in a first set up or mode in which exercise
device 20 facilitates concurrent exercise of both the legs or lower
body of a person and the arms or upper body of the person. FIG. 3
illustrates exercise device 20 in a second alternative set up or
mode in which exercise device 20 facilitates just the exercise of
the legs or lower body of the person. As will be described
hereafter, exercise device 20 provides a relatively uncomplicated
and low-cost mechanism for switching between the two modes in a
time efficient manner.
[0021] Exercise device 20 generally includes frame 22, control
interface 23, guides 24, foot links 26, swing arms 28, connection
links 30, frame retainer 31 and control interface 23. In the
particular example illustrated, exercise device 20 includes a pair
of substantially identical foot links 26, a pair of swing arms 28
and a pair of connection links 30. However, for purposes of
illustration and ease of discussion, FIG. 1-3 illustrate one of
each pair.
[0022] Frame 22 comprises one or more structures configured to
support the remaining structures or components of exercise device
20 relative to a wall or floor. In the particular example
illustrated, frame 22 includes a generally horizontal portion 34
and a vertical portion 36. Horizontal portion 34 extends along a
floor or other support surface while vertical portion 36 extends
upwardly from horizontal portion 34. Horizontal portion 34 supports
guide 24 while portion 36 supports swing arms 28 and control
interface 23. Although portions 34 and 36 are illustrated as each
being generally linear, portions 34 and 36 may have a variety of
sizes, shapes and configurations and may be composed of multiple
segments which are integral, which are welded to one another, which
are bonded to one another or which are fastened or otherwise
secured to one another.
[0023] Control interface 23 comprises an electronic device
configured to interface with a person using exercise device 20. In
one embodiment, interface 23 facilitates input of instructions or
commands by the person or from an external source. Such commands
may be used to set or establish levels of resistance, speed or
other settings to vary or control work out parameters. In one
embodiment, interface 23 may additionally or alternatively be
configured to provide the person with information or feedback
regarding the current workout. In particular embodiments, interface
23 may additionally be configured to provide a person using
exercise device 20 with information regarding exercise goals, past
workouts, recommended settings or entertainment information, such
as news, videos or music. In one embodiment, control interface 23
may be configured to communicate with other external electronic
devices, such as other computers, servers come exercise devices or
the like in a wired or wireless fashion.
[0024] In one embodiment, interface 23 may include one or more
displays that provide the user with visual information. In one
embodiment, interface 23 may additionally include one or more
speakers providing audible information or entertainment. Interface
23 may additionally include one or more microphones facilitating
entry of audible commands in addition to or as an alternative to
manual interfaces, such as touchpads, push buttons, slides,
toggles, switches or touch screens.
[0025] Guide 24 (schematically shown) comprises an arrangement of
one or more structures or one or more mechanisms configured to
facilitate movement of foot link 26 relative to frame 22 in one or
more pre-described or predetermined paths or manners. Guide 24
controls movement of foot link 26 such that motion or movement of
foot link 26 has a reciprocating component. In one embodiment,
guide 24 is configured such that foot link 26 reciprocates
generally towards and away from control interface 23 in forward and
rearward directions. For example, in one embodiment, guide 24 may
be configured such that foot link 26 linearly reciprocates in the
directions indicated by arrows 40, wherein the movement of foot
link 26 is substantially contained within a single plane. An
example of such motion may be found in skier exercise devices that
simulate cross-country skiing. In another embodiment, guide 24 may
be configured such that foot link 26 moves in an elliptical orbit
while reciprocating in forward and rearward directions. In yet
other embodiments, guide 24 may be configured such that foot link
26 reciprocates in a generally vertical direction, either along a
linear path or along a circular or elliptical path. An example of
such motion may be found in stepper exercise devices. In yet other
embodiments, guide 24 may be configured to facilitate movement of
foot link 26 in other motions relative to frame 22. Although guide
24 is illustrated as extending between frame 22 and foot link 26,
in other embodiments, guide 24 may be located rearwardly or
forwardly of foot link 26 and may extend over or above link 26.
[0026] Each foot link 26 comprises one or more structures
configured to engage a person's leg or foot such that movement of
the person's leg or foot causes movement of foot link 26. For
example, in one embodiment, foot link 26 may include a foot rest or
peddle (not shown) upon which a person may place his or her foot
and apply force to move and reciprocate foot link 26. Foot link 26
is configured to cooperate with guide 24 such that reciprocal
movement of foot link 26 is directed by guide 24.
[0027] Swing arm 28 comprises one or more structures configured to
be gripped by a person's hand and to be reciprocated to exercise a
person's arm and upper body. Swing arm 28 includes a gripping
portion 42, an intermediate portion 44 pivotably connected to frame
22 and an end to portion 46 pivotably connected to connection links
30. Gripping portion 42 comprises that portion of swing arm 28
configured to be grasped or gripped by a person's hand.
Intermediate portion 44 facilitates pivotal movement of swing arm
28 about a substantially horizontal axis 48. In other embodiments,
swing arm 28 may be movably supported in other fashions by frame
22. For example, in other embodiments, swing arm 28 may linearly
translate or slide back and forth in a reciprocal manner. Although
swing arm 28 is illustrated as comprising two generally linear
segments, in other embodiments, swing arm 28 may have other shapes,
relative dimensions and configurations.
[0028] Connection link 30 comprises one or more segments or links
configured to connect foot link 26 and swing arm 28 such that
movement of foot link 26 and swing arm 28 is coordinated. In one
embodiment, connection link 30 is configured and appropriately
connected to foot link 26 and swing arm 28 such that when foot link
26 is moving forwardly (towards control interface 23), swing arm 28
is moving rearwardly and when foot link 26 is moving rearwardly,
swing arm 28 is moving forwardly. In another embodiment, connection
link 30 may alternatively be configured and appropriately connected
between foot link 26 and swing arm 28 such that when foot link 26
is moving forwardly, swing arm 28 is also moving forwardly and when
foot link 26 is moving rearwardly, swing arm 28 is also moving
rearwardly. In yet another embodiment, connection link 30 may be
configured such that when foot link 26 is moving upwardly, swing
arm 28 is also moving upwardly and when foot link 26 is moving
downwardly, swing arm 28 is also moving downwardly. In still other
embodiments, connection link 30 may be configured such that when
foot link 26 is moving upwardly, swing arm 28 is moving downwardly
and vice versa.
[0029] In the particular example embodiment illustrated, connection
link 30 has a first portion 52 pivotably connected to end portion
46 of swing arm 28 and a second portion 54 connected to foot link
26. In the example illustrated, portion 54 is pivotably connected
to foot link 26. In the embodiment illustrated, end portions 52 and
54 facilitate pivotal movement about at least horizontal axis. In
other embodiments, portion 54 may be connected to foot link 26 in a
non-pivotable manner.
[0030] Frame retainer 31 comprises a mechanism configured to secure
and retain swing arm 28 against movement when swing arm 28 is
disconnected from foot link 26. In the particular example
illustrated, frame retainer 31 is configured to retain connection
links 30 against movement when connection links 30 is disconnected
from foot link 26, thereby also securing swing arm 28 against
movement. In the particular example illustrated, frame retainer 31
is associated with frame 22. In other embodiments, frame retainer
31 may be coupled to or connected to other structures of exercise
device 20.
[0031] In one embodiment, connection link 30 is configured to be
disconnected from and connected to frame retainer 31 in a tool-less
manner. In other words, connection link 30 may be separated and
disconnected from or connected to frame retainer 31 in a manual
fashion without a person having to acquire and use a separate tool,
such as a wrench, screwdriver or the like, to remove or disconnect
a fastener. As a result, swing arms 28 may be more easily disabled
and exercise device 20 may be more easily converted between the
first exercise mode and the second exercise mode in less time.
According to one embodiment, connection link 30 is configured to be
connected to frame retainer 31 with a single hand of a person. In
other embodiments, connection link 30 may alternatively be
removably connected to frame retainer 31 by one or more fasteners
or other mechanisms which require tools or which require two hand
for disconnecting link 30 from frame retainer 31.
[0032] For purposes of this disclosure, the term "coupled" shall
mean the joining of two members directly or indirectly to one
another. Such joining may be stationary in nature or movable in
nature. Such joining may be achieved with the two members or the
two members and any additional intermediate members being
integrally formed as a single unitary body with one another or with
the two members or the two members and any additional intermediate
member being attached to one another. Such joining may be permanent
in nature or alternatively may be removable or releasable in
nature. The term "operably coupled" shall mean that two members are
directly or indirectly joined such that motion may be transmitted
from one member to the other member directly or via intermediate
members.
[0033] According to one embodiment, frame retainer 31 secures
connection link 30 with a projection and detent arrangement,
wherein connection link 30 includes one of a projection and a
detent and wherein frame retainer 31 comprises the other of the
projection and the detent. The detent receives the projection to
secure connection link 30 against movement in forward and rearward
directions as indicated by arrows 40 in FIG. 1. In one embodiment,
frame retainer 31 comprises one of a projection and a detent
extending along an axis substantially parallel to the axis in which
the other of the projection and the detent associated with
connection link 30 extends when connected to foot link 26. In
another embodiment, frame retainer 31 may comprise one of a
projection and a detent extending along an axis non-parallel, such
as perpendicular, to the axis in which the other of the projection
and the detent associated with connection link 30 extends when
connected to foot link 26. In such an embodiment, connection link
30 may be additionally configured to rotate or swivel to facilitate
connection with retainer or 31. In one embodiment, frame retainer
31 may include a quick release mechanism for providing a positive
lock or positive securement of connection link 30 to frame 22. In
yet other embodiments, frame retainer 31 may have other
configurations for securing connection link 30 or swing arm 28.
[0034] FIGS. 1 and 2 illustrate exercise device 20 in the first
mode in which both a person's upper body and lower body are
exercised. FIG. 1 illustrates foot link 26 in a forward most
position which results in movement of swing arm 28 to a rearward
most position. Conversely, FIG. 2 illustrates foot link 26 moved to
a rearward most position which results in swing arm 28 being moved
to a forward most position.
[0035] As noted above, exercise device 20 includes a pair of foot
links 26, a pair of connection links 30 and a pair of swing arms
28, wherein the only one of each pair is shown. When one of foot
links 26 is in the forward most position, the other of the links 26
is in the rearward most position. Likewise, when one of swing arms
28 is in the forward most position, the other of swing arms 28 is
in the rearward most position.
[0036] FIG. 3 schematically illustrates exercise device 20 in the
second exercise mode in which swing arms 28 are disabled or
otherwise disengaged from foot link 26 so as to not move in
coordination with foot links 26. As a result, when exercise device
20 is in the second mode, a person may exercise just their lower
body or legs without swing arms 28 reciprocating back-and-forth
during such exercise. When exercise device 20 is in the second mode
shown in FIG. 3, swing arms 28 are stowed and generally stationary
while foot link 26 continues to be reciprocated by the leg or foot
of the person using exercise device 20. In particular embodiments,
one of swing arms 28 may be disabled while the other of swing arms
28 remains connected to its corresponding foot link 26.
[0037] When exercise device 20 is in the second exercise mode shown
in FIG. 3, connection link 30 is disconnected from foot link 26. As
a result, swing arm 28 is disconnected from foot link 26.
Connection link 30 is configured to be disconnected from foot link
26 in a tool-less manner. In other words, connection link 30 may be
separated and disconnected from foot link 26 in a manual fashion
without a person having to acquire and use a separate tool, such as
a wrench, screwdriver or the like, to remove or disconnect a
fastener. As a result, swing arms 28 may be more easily disabled
and exercise device 20 may be more easily actuated to a second
exercise mode in less time. According to one embodiment, connection
link 30 is configured to be disconnected from foot link 26 with a
single hand of a person. In other embodiments, connection link 30
may alternatively be removably connected to foot link 26 by one or
more fasteners or other mechanisms which require tools or which
require two hand for disconnecting link 30 from foot link 26.
[0038] According to one embodiment, connection link 30 is removably
connected to foot link 26 by a foot link retainer 60 (part of a
projection and detent mechanism) which also pivotably connects link
30 to foot link 26. This duel nature of foot link retainer 60
reduces complexity of exercise device 20. According to one
embodiment, foot link retainer 60 comprises a projection associated
with foot link 26 and a corresponding detent associated with
connection link 30, wherein the detent receives the projection to
releasably and pivotably connect link 32 foot link 26. For example,
in one embodiment, a projection may comprise a pin while the detent
comprises a ring. In another embodiment, foot link retainer 60 may
alternatively comprise a projection associated with link 30 and a
corresponding detent associated with foot link 26. In still other
embodiments, foot link retainer 60 may have other
configurations.
[0039] According to one embodiment, frame retainer 31 and foot link
retainer 60 comprise similar connection mechanisms, mechanically
operating in similar fashions to releasably retain link 30. In one
embodiment, frame retainer 31 and connection 68 have an arrangement
of structures or components coupled to frame 22 and foot link 26,
respectively, which are similar to one another and which both
engage, in the same fashion, an arrangement of structures provided
at an end portion of link 30. In other words, frame retainer 31 and
foot link retainer 60 releasably connect to a same single structure
or mechanism associated with an end portion of link 30. According
to one embodiment, a majority of the components or parts or the
most complex or more expensive parts utilized to provide releasable
connection of link 32 either frame 22 or foot link 26 are provided
on the end portion of link 30. As a result, rather than the
majority of parts or more expensive parts being duplicated for each
of frame retainer 31 and foot link retainer 60, the majority of
such parts or the more expensive parts need only be provided once
in a single shared location on link 30, reducing complexity and
cost of exercise device 20.
[0040] FIG. 3 illustrates connection link 30 disconnected from foot
link 26 and alternatively secured by frame retainer 31. In the
example embodiment illustrated, when connection link 30 is secured
by frame retainer 31, gripping portion 42 of swing arm 28 extends
rearwardly of the forward most position of swing arm 28 when swing
arm 28 is in a first exercise mode. In particular example
illustrated, gripping portion 42 of swing arm 28 extends rearwardly
of control interface 23 when swing arm 28 is stowed and secured by
frame retainer 31. According to one embodiment, when swing arm 28
is in the disabled position, gripping portions 42 are located in
alignment with one another on opposite transverse sides and are
longitudinally located so as to serve as handle bars or grips which
a person may grasp while exercising (reciprocating) his or her legs
or lower body using foot link 26.
[0041] FIGS. 4-8 illustrate exercise device 120, a particular
example of exercise device 20. Like exercise device 20, exercise
device 120 is configured to be more easily switched between a first
set up or exercise mode in which exercise device 120 facilitates
concurrent exercise of both the legs or lower body of a person and
the arms or upper body of the person and a second alternative set
up or exercise mode in which exercise device 120 facilitates just
the exercise of the legs or lower body of the person. As shown by
FIG. 4, exercise device 120 includes frame 122, control interface
123, guide 124, foot links 126, swing arms 128, connection links
130 (both of which are shown in FIG. 6), frame retainers 131 (both
of which are shown in FIG. 5) and toot link retainers 160.
[0042] Frame 122 comprises one or more structures configured to
support the remaining structures are components of exercise device
120 relative to a wall or floor. In the particular example
illustrated, frame 122 includes a generally horizontal portion 134,
a vertical portion 136, stabilizer portions 137, 138 and swing arm
supports 140. Horizontal portion 134 extends along a floor or other
support surface while vertical portion 136 extends upwardly from
horizontal portion 134. Horizontal portion 134 supports guide 24
while portion 136 supports swing arms 128 and control interface
123.
[0043] Stabilizer portions 137, 138 transversely extend outwardly
from horizontal portion 134 to stabilize and support horizontal
portion 134. In the example illustrated, stabilizer portion 137 is
located at a rear 200 of frame 122 while stabilizer portion 138 is
proximate a front 202 of frame 122. In other embodiments,
stabilizer portions 137, 138 may have other configurations, may be
provided in other locations along frame 122 or may be omitted.
[0044] Swing arm supports 140 transversely project from vertical
portion 136 proximate to front 202 of frame 122. Swing arm supports
140 pivotably support swing arms 128 for pivotable or rotational
movement about axis 148. In particular embodiments, swing arm
supports 140 may apply a selected and controlled varying resistance
to pivotal movement of swing arms 128. In other embodiments, this
feature may be omitted.
[0045] Control interface 123 comprises an electronic device
configured to interface with a person using exercise device 120. In
one embodiment, interface 123 facilitates input of instructions or
commands by the person or from an external source. Such commands
may be used to set or establish levels of resistance, speed or
other settings to vary or control work out parameters. In one
embodiment, interface 123 may additionally or alternatively be
configured to provide the person with information or feedback
regarding the current workout. In particular embodiments, interface
123 may additionally be configured to provide a person using
exercise device 120 with information regarding exercise goals, past
workouts, recommended settings or entertainment information, such
as news, videos or music. In one embodiment, control interface 123
may be configured to communicate with other external electronic
devices, such as other computers, servers or portable devices in a
wired or wireless fashion.
[0046] In one embodiment, interface 123 may include one or more
displays that provide the user with visual information. In one
embodiment, interface 123 may additionally include one or more
speakers providing audible information or entertainment. Interface
123 may additionally include one or more microphones facilitating
entry of audible commands in addition to or as an alternative to
manual interfaces, such as touchpads, push buttons, slides,
toggles, switches or touch screens.
[0047] Guide 124 comprises an arrangement of one or more structures
or one or more mechanisms configured to facilitate movement of foot
links 126 relative to frame 122 in one or more pre-described or
predetermined paths or manners. Guide 124 controls movement of foot
links 126 such that motion or movement of foot links 26 has a
reciprocating component. In the embodiment illustrated, guide 24 is
configured such that foot links 126 reciprocate in an alternating
fashion with respect to one another generally towards and away from
control interface 23 in forward and rearward directions. In the
example illustrated, guide 124 is configured such that rearward
portions of foot links 126 are constrained to move in an orbital
path such that the overall motion of foot links 126 is
elliptical.
[0048] As shown by FIG. 4, guide 124 includes orbital mechanism
210, guide tracks 212 and engagement rollers 214. Orbital mechanism
210 comprises a mechanism operably connected to rearward portions
of foot links 126 and configured so as to constrain movement of
rear portions of foot links 126 in an orbital path. In embodiment,
orbital mechanism 210 comprises a flywheel (not shown) rotationally
supported about a central axis and a pair of crank arms (not
shown), wherein one of the crank arms has a first end rotationally
supported about the central axis and a second end rotationally
connected to one of swing arms 128 and wherein the other of the
crank arms has a first end rotationally supported about the central
axis and a second end rotationally connected to the other of swing
arms 128. An example orbital mechanism 210 is described in
co-pending US Patent Application Ser. No. 11/054,376, published on
Aug. 24, 2006 as publication US 2006/0189445, a full disclosure
which is hereby incorporated by reference.
[0049] Guide tracks 212 comprise elongate surfaces proximate a
forward end of foot links 126 and configured to guide and direct
reciprocal movement of a forward end of foot links 126. In the
embodiment illustrated down a guide tracks 212 are inclined. For
example, one embodiment, guide tracks 212 are inclined at
approximately 30 degrees. In another embodiment, guide tracks 212
may alternatively be inclined at other angles, may be level or may
be declined. In the embodiment illustrated, guide tracks 212 have
an upper surface configured to laterally contain engagement rollers
214. In one embodiment, guide tracks 212 have a generally U-shaped
cross-sectional configuration size and shape to mate with
engagement rollers 214 to assist in lateral containment of rollers
214 on track 212. In other embodiments, guide tracks 212 may have
other configurations.
[0050] Engagement rollers 214 comprise rollers rotationally
supported at forward portion of foot links 126 that are configured
to roll and move along their respective guide tracks 212. In the
embodiment illustrated, each engagement in roller 214 is laterally
constrained within a substantially U-shaped channel. In other
embodiments, engagement rollers 214 and tracks 212 may have other
cooperating configurations. In yet other embodiments, engagement
rollers 214 may be omitted, wherein other low friction engagement
members or structures are coupled to foot links 126 so as to guide
and facilitate movement of foot links 126 along guide tracks 212.
In still other embodiments, guide tracks 212 and engagement rollers
214 may be switched such that engagement rollers 214 are replaced
with one or more rotatable rollers and wherein a downwardly facing
track is coupled to forward ends 224 of each of supports 220. In
such an embodiment, the downwardly facing groove of the track
receives the rollers and moves along the rollers. In still other
embodiments, guide 124 may of other configurations.
[0051] Each foot link 126 comprises one or more structures
configured to engage a person's leg or foot such that movement of
the person's leg or foot causes movement of foot link 126. In the
embodiment illustrated, each foot link 126 includes a support 220
and a foot rest 222. Support 220 comprises an elongate bar, rod or
otherwise rigid structure having a forward end 224 supporting
engagement roller 214 and a rear end 226 connected to orbital
mechanism 210. Each foot rest 222 comprises a petal or other
surface upon which a person may place his or her foot to transfer
force to foot link 126. In one embodiment, foot rests 222 are
configured to form toe straps and/or toe and heel cups which aid in
forward motion recovery at the end of a rearward or forward
striding motion of a user's foot.
[0052] Swing arms 128 comprise one or more structures configured to
be gripped by a person's hand and to be reciprocated to exercise a
person's arm and upper body. Each swing arm 128 includes a gripping
portion 142, an intermediate portion 144 pivotably connected to
support 140 of frame 122 and an end to portion 146 pivotably
connected to connection link 130. Gripping portion 142 comprises
that portion of swing arm 128 configured to be grasped or gripped
by a person's hand. Intermediate portion 144 facilitates pivotal
movement of swing arm 128 about the substantially horizontal axis
148. Although swing arms 128 are illustrated as being bowed, in
other embodiments, swing arms 128 may have other shapes, relative
dimensions and configurations.
[0053] Each connection link 130 comprises one or more segments or
links configured to connect foot link 126 and swing arm 128 such
that movement of foot link 126 and swing arm 128 is coordinated. In
one embodiment, connection link 130 is configured and appropriately
connected to foot link 126 and swing arm 128 such that when foot
link 126 is moving forwardly (towards control interface 123), swing
arm 128 is moving rearwardly. When foot link 126 is moving
rearwardly, swing arm 128 is moving forwardly. In other words, when
foot link 126 is in a forward most position, the connection between
connection link 130 and swing arm 128 is on an opposite side of
axis 148 as gripping portion 142.
[0054] FIGS. 5-7 illustrate connection link 130 in more detail. As
shown by FIG. 5, connection link 130 includes a first portion 152
pivotably connected to swing arm 128 and a second end portion 154
pivotably connected to support 220 of foot link 126. Portion 152
pivotably connects connection link 130 to swing arm 128 for pivotal
movement about a substantially horizontal axis 228. In the example
illustrated, portion 152 includes a swivel joint 230 which enables
connection link 130 to be rotated about axis 232, which is
perpendicular to axis 228, to facilitate connection of end portion
154 to frame retainer 131 as will be described hereafter.
[0055] In one embodiment, swivel joint 230 includes an eyelet 234
through which a pin 236 extending along an axis 228 extends to
pivotably connect eyelet 234 to swing arm 128. Eyelet 234 further
includes an externally threaded rod or shaft rotatably received
within an internally threaded bore of link 130. In another
embodiment, eyelet 234 may have other configurations which
facilitate relative rotation of connection link 130 relative to
eyelet 234 about axis 232 while axially retaining connection link
130 relative to eyelet 234. In still other embodiments wherein end
portion 154 is not rotated for connection with frame retainer 131,
such as when frame retainer 131 extends parallel to axis 228,
swivel joint 230 may be omitted.
[0056] End portion 154 comprises that portion of connection link
130 configured to be pivotably connected to foot link 126 by foot
link retainer 160. As shown by FIG. 6, foot link retainer 160 is
coupled to foot link 126 and includes a projection 250 extending
along axis 252 and a base portion 254. As shown by FIG. 7, end
portion 154 of connection link 130 comprises a ring 260 having a
bore 262 rotationally supported by a spherical bearing 264. As
shown by FIG. 5, when end portion 154 is connected to foot link
126, bore 262 receives projection 250. As a result, forward or
rearward movement of foot link 126 is transmitted to swing arm 128
by connection link 130. At the same time, end portion 154 is
permitted to rotate about axis 252 pivotably connecting link 130
and foot link 126.
[0057] In the particular embodiment illustrated, end portion 154 is
further configured to be magnetically retained upon projection 250.
In one embodiment, ring 260 comprises a ring magnet 268 and a
retainer 270, wherein projection 250 and/or base portion 254 are
either magnetic or are formed from a magnet attracted material,
such as iron or steel. In one embodiment, retainer 270 is formed
from a non-magnetic material, such as a plastic or polymer, wherein
retainer 270 is sufficiently thin so as to not sufficiently
interfere with the magnetic field of ring magnet 268 to inhibit
magnetic retention of end portion 154. In yet another embodiment,
ring 260 or its retainer 270 may be formed from a magnetic
attracted material, such as iron or steel, while projection 250
and/or base portion 254 is formed from a magnetic material. In yet
other embodiments, neither end portion 154 nor projection 250 may
be formed from a magnetic material.
[0058] FIGS. 7 and 8 illustrates frame retainer 131 in more detail.
As shown by FIG. 7, frame retainer 131 comprises a projection 274
extending from a base 276. Projection 274 is configured to be
received within bore 262 of end portion 154. As shown by FIG. 5,
projection 274 extends along an axis 278 that is nonparallel to
axis 252. In one embodiment, axis 278 is substantially
perpendicular to axis 252. As noted above, connection link 130 is
configured to be rotated about axis 232 while connected to swing
arm 128 so as to reorient bore 262 from a first position in which
bore 262 extends along axis 252 to a second orientation in which
bore 262 is aligned with and extends along axis 278. Once bore 262
is in alignment with axis 278, end portion 154 is lowered onto
projection 274 with projection 274 received within bore 262. As a
result, forward or rearward reciprocal movement of connection link
130 and pivotal movement of swing arm 128 is restricted or
prevented by frame retainer 131. Swing arm 128 is stowed in a
stationary fashion.
[0059] In one embodiment, surrounding portions of frame retainer
131 are formed from one or more magnetic materials or one or more
magnet attracted materials to assist in retaining connection link
130 in a retained state and to prevent accidental dislodging of
connection link 130. For example, in one embodiment in which ring
260 includes magnetic ring 268, projection 274 or base 276 may be
formed from a magnetic attracted material, such as iron or steel.
In other embodiments, projection 274 or base 276 may be formed from
a magnetic material. In yet other embodiments, such portions may
alternatively be nonmagnetic.
[0060] Overall, connection link 130 provides a secure connection
link between foot link 126 and swing arm 128 such that translation
of foot link 126 along track 212 may be transmitted to swing arm
128. At the same time, end portion 154 may be disconnected from
foot link 126 in a tool-less manner, disconnecting swing arm 128
from foot link 126. In particular, a person simply needs to pull
end portion 154 off of projection 250 with sufficient force so as
to overcome the magnetic attraction therebetween.
[0061] When swing arm 128 is disconnected from foot link 126 such
that exercise device 120 is in the second exercise mode, end
portion 154 may be easily connected to frame retainer 131 in a
tool-less manner. A person simply needs to rotate connection link
130 and align bore 262 with projection 274 while lowering
connection link 130 onto frame retainer 131. Because projection 274
extends along a generally vertical axis 278, gravity assists in
retaining end portion 154 on frame retainer 131. Additional
retention of end portion 154 on frame retainer 131 is provided by a
magnetic attraction.
[0062] When a person desires to switch exercise device 120 to the
first exercise mode, the person simply needs to lift connection
link 130 with sufficient force to overcome gravity and the magnetic
attraction to withdraw projection 274 from bore 262. Thereafter,
the person rotates connection link 130 about axis 232 to align bore
262 with axis 252. Thereafter, the person simply moves connection
link 130 in a lateral direction until projection 250 is received
within bore 262.
[0063] FIGS. 5-8 illustrate just one of many variations for
connection link 130, frame retainer 131 and foot link retainer 160.
Although connection link 130 is illustrated as having swivel joint
230 at end portion 152, in other embodiments, end portion 154 may
alternatively be connected to a remainder of connection link 130 by
a similar swivel joint. For example, ring 260 may be supported by a
threaded shaft which is threadably received within a threaded bore
of connection link 130. Although swivel joint 230 is illustrated as
having and eyelet 234 extending from an externally threaded shaft
that is received within an internally threaded bore, in other
embodiments, eyelet 234 may alternatively extend from an internally
threaded bore that receives an externally threaded shaft associated
with the remainder of connection link 130. Although connection link
130 is illustrated as substantially a single link, in other
embodiments, connection link 130 may include additional links. In
one embodiment, connection link 130 may include multiple links
which are interconnected by a swivel joint permitting relative
rotation about axis 232. For example, connection link 130 may
include a pair of links joined by intermediate externally threaded
member received within internally threaded bores associate with
each link. In still other embodiments wherein projection 274
extends along an axis substantially parallel to axis 252, swivel
joint 230 may be omitted.
[0064] FIGS. 9 and 10 illustrate exercise device 320, another
embodiment of exercise device 20 (shown in FIGS. 1-3). Like
exercise device 120, exercise device 320 includes frame 122,
control interface 123, guide 124, foot links 126, and swing arms
128 (each of which are shown in FIGS. 4-6). Exercise device 320 is
similar to exercise device 120 except that exercise device 320
includes connection links 330 (one of which is shown) and frame
retainer 331 in lieu of connection link 130 and frame retainer 131,
respectively. Although not illustrated, exercise device 320 further
includes a foot link retainer substantially identical to frame
retainer 331, but extending from each foot link 126 rather than
frame 122. Like foot link retainer 160, the foot link retainer of
exercise device 320 is configured to engage connection link 330 to
operably couple connection link 330 to the associated foot link
126.
[0065] As shown by FIGS. 9 and 10, connection link 330 is
substantially identical to connection link 130 except that
connection link 330 includes end portion 354 in place of end
portion 154. End portion 354 is configured to releasably connect
link 330 to frame retainer 331 or alternatively to connect
connection link 332 the foot link retainer (not shown). End portion
354 includes spherical bearing 364, fastener 366 and quick
disconnect component 368. Spherical bearing 364 is rotationally
supported at end portion 354. Fastener 366 extends through
spherical bearing 364 and is connected to quick disconnect
component 368. In the particular example illustrated, quick
disconnect component 368 includes a threaded bore 370 and fastener
366 comprising a threaded bolt threaded into bore 370 to secure
component 368 to spherical bearing 364 and end portion 354 of
connection link 330. In other embodiments, component 368 may be
secured to spherical bearing 364 in other fashions.
[0066] Quick disconnect component 368 is configured to releasably
connect connection link 330 to frame retainer 331 and frame 122
when exercise device 320 is in the second exercise mode in which
swing arms 128 (shown in FIG. 4) are stationarily retained during
reciprocation or other movement of foot links 126 (shown in FIG.
4). Component 368 generally includes a body 372, engagement members
374 and bias members 376. Body 372 forms an interior bore 378
configured to receive at least portions of frame retainer 331 (or
portions of the foot link retainer) and one or more radially
extending cavities 380 in which engage members 374 and bias members
376 are contained.
[0067] Engagement members 374 comprise one or more members within
cavities 380 which are movable between an extended position in
which engage members partially project into bore 378 for engagement
with retainer 331 and a retracted position in which a greater
extent of members 374 is withdrawn from bore 378, permitting
retainer 331 be withdrawn from bore 378. In the example
illustrated, members 374 comprise balls. In other embodiments,
members 374 may comprise rods, pins or other structures.
[0068] Bias members 376 bias engagement members 374 to the extended
position. In the example illustrated, bias members 376 comprise
compression springs. In other embodiments, bias members 376 may
comprise other forms of springs or resilient biasing
mechanisms.
[0069] Frame retainer 331 comprises a projection, such as a shaft,
pin, rod and the like which includes a circumferential channel 384.
Frame retainer 331 is configured to be inserted into bore 378 such
that retainer 331 engages members 374 to move members 374 against
the bias force provided by members 376 to the retracted position
until channel 384 is positioned opposite to or across from members
374. At such point in time, bias members 376 urge engagement
members 374 to the extended position in which members 374 project
into channel 34 to axially retain component 368 and link 330 on
retainer 331. To disconnect link 330, a person merely pulls upon
link 330 with a sufficient force such that retainer 331 engages and
moves members 374 in a radially outward direction to the retracted
positions, permitting withdrawal of retainer 331 from channel 378.
As a result, component 368 and retainer 331 cooperate to facilitate
disconnection of link 330 without tools and with a single hand.
Likewise, component 368 and the foot link retainer cooperate to
facilitate disconnection of link 330 without tools and with a
single hand.
[0070] In other embodiments, other quick disconnect arrangements or
mechanisms may be utilized. For example, in other embodiments,
component 368 may additionally be provided with a resiliently
biased sleeve that slides over body 372 and that is resiliently
biased by a spring to a first position in which the sleeve engages
members 374 to retain members 374 in their extended positions.
Manual movement or retraction of the sleeve against the spring to a
second position permits members 374 to move radially outward to
their retracted positions, enabling retainer 331 to be withdrawn.
In such an embodiment, members 376 may be omitted.
[0071] FIGS. 11-13 illustrate exercise device 420, another
embodiment of exercise device 20 (shown in FIGS. 1-3). Like
exercise device 120, exercise device 420 includes frame 122,
control interface 123, guide 124, foot links 126, and swing arms
128 (each of which are shown in FIGS. 4-6). Exercise device 320 is
similar to exercise device 120 except that exercise device 320
includes connection links 430 (one of which is shown) and frame
retainer 431 in lieu of connection link 130 and frame retainer 131,
respectively. Although not illustrated, exercise device 420 further
includes a foot link retainer substantially identical to frame
retainer 431, but extending from each foot link 126 rather than
frame 122. Like foot link retainer 160, the foot link retainer of
exercise device 420 is configured to engage connection link 430 to
operably couple connection link 430 to the associated foot link
126.
[0072] As shown by FIGS. 11-13, connection link 430 is
substantially identical to connection link 130 except that
connection link 430 includes end portion 454 in place of end
portion 154. End portion 454 is configured to releasably connect
link 432 frame retainer 431 or alternatively to connect connection
link 432 the foot link retainer (not shown). End portion 454
includes spherical bearing 464, body 466, engagement members 468,
plunger or piston 470 and bias member 472. Spherical bearing 364 is
rotationally supported at end portion 354. Spherical bearing 364 is
connected to and rotationally supports body 466.
[0073] Body 466 is secured to spherical bearing 464. In his the
example illustrated, body 466 is threaded to spherical bearing a
464. In other embodiments, body 466 may be secured to spherical
bearing 464 in other fashions. As shown by FIG. 12, body 466 forms
bores 476, 478 which slide a bully receive piston 470. Bore 478 is
enlarged so as to additionally receive bias member 472. Body 466 in
further includes radially extending cavities 480 which receive
engagement members 468 and permit engagement members 468 to move
radially. Body 466 is further configured to be inserted into
retainer 431.
[0074] Engagement members 468 comprise one or more members within
cavities 480 which are movable between an extended position in
which engagement members 468 partially project into from body 466
for engagement with retainer 431 and a retracted position in which
a greater extent of members 468 is received within body 466,
permitting body 466 to be withdrawn from retainer 431. In the
example illustrated, members 468 comprise balls. In other
embodiments, members 468 may comprise rods, pins or other
structures.
[0075] Piston 470 comprises one or more structures configured to
either inhibit or facilitate movement of members 468 between the
extended positions in the retracted positions. Piston 470 is
manually actuatable between a locked or retaining position or state
(shown in FIG. 12) in which piston 470 retains members 468 in their
extended positions and an unlocked or released position or state in
which piston 470 permits members 468 to move radially inwardly to
an extent such that body 466 may be withdrawn from retainer
431.
[0076] Piston 470 includes an elongate shaft 484 which terminates
at a larger head 486. Shaft 484 extends from head 486 and includes
recess or cavity 488. Cavity 488 is configured to sufficiently
receive one or more of members 468 to permit members 468 to move to
their retracted positions, permitting body 466 to be withdrawn from
retainer 431. In one embodiment, cavity 48 may comprises
circumferential groove. In another embodiment, cavity 468 may
comprise one or more opposing indentations.
[0077] Head 486 extends from shaft 470 and is received at lease
partially within cavity 472. Head 486 serves as a manual pushbutton
for actuation of piston 470.
[0078] Bias member 478 resiliently biases piston 470 to its
retaining state. In the example illustrated, bias member 478
comprises a compression spring captured between head 486 and body
466 within cavity 472. Depressment of head 46 against the bias
force provided by member 478 moves shaft 476 downward (as seen in
FIG. 12) to locate cavity 48 across from members 468, permitting
members 468 to move radially inward such that body 466 may be
withdrawn from retainer 431.
[0079] Retainer 431 comprises a structure coupled to frame 122 and
configure to claw Paris with end portion 454 to releasably secure
link 430 to frame 122. Retainer 431 comprises an elongate sleeve
having an axial face 490 against which members 468 bear against
when body 466 is sufficiently inserted into retainer 431 and while
piston 470 is in the retaining position or state. Because retainer
431 is configured such that members 468 bear against its axial face
490, retainer 431 may omit internal grooves or channels for
engaging the members 468, reducing the cost and complexity of
retainer 431. In other embodiments, retainer 431 may alternatively
include an internal circumferential groove or internal detents
which receive members 468 when members 468 are in their extended
positions.
[0080] FIGS. 14-15 illustrate exercise device 520, another
embodiment of exercise device 20 (shown in FIGS. 1-3). Like
exercise device 120, exercise device 520 includes frame 122,
control interface 123, guide 124, foot links 126, and swing arms
128 (each of which are shown in FIGS. 4-6). Exercise device 520 is
similar to exercise device 520 except that exercise device 520
includes connection links 530 (one of which is shown) and frame
retainer 531 in lieu of connection link 130 and frame retainer 131,
respectively. Although not illustrated, exercise device 520 further
includes a foot link retainer substantially identical to frame
retainer 531, but extending from each foot link 126 rather than
frame 122. Like foot link retainer 160, the foot link retainer of
exercise device 520 is configured to engage connection link 530 to
operably couple connection link 530 to the associated foot link
126.
[0081] As shown by FIGS. 14 and 15, connection link 530 is
substantially identical to connection link 130 except that
connection link 530 includes end portion 554 in place of end
portion 154. End portion 554 is configured to releasably connect
link 530 to frame retainer 531 or alternatively to connect
connection link 532 the foot link retainer (not shown). End portion
554 includes spherical bearing 564 and a shoulder or face 566.
Spherical bearing 564 includes a bore 568 configured to slidably or
releasably receive portions of retainer 531 to releasably connect
link 530 to retainer 531 and frame 122. Face 566 comprises a
surface against which retainer 531 may bear against to releasably
retain link 530.
[0082] As shown by FIGS. 14 and 15, retainer 531 includes a shaft
or pin 572 and a catch 574. Pin 572 comprises a structure
configured to be rotationally received within bore 568 and to
project through bore 568.
[0083] Catch 574 comprises one or more structures configured to at
least partially wrap about or around end portion 554 so as to
engage opposite sides of end portion 554 when pin 572 is received
within bore 568. In the particular example illustrated, catch 574
includes a manually graspable extension 576 including a hook 578
which extends over and bears against face 566. Hook 578 is a
movable between an engaged position (shown in FIG. 15) in which
hook 578 bear is against face 566 to retain end portion 554 axially
against retainer 531 and a disengaged position in which hook 578 is
radially withdrawn from face 566, permitting end portion 554 to be
lifted away from retainer 531.
[0084] In the example illustrated, catch 574 is integrally formed
as part of a single unitary body out of one or more materials, such
as one or more polymers, and is dimensioned so as to permit hook
578 to flex between the engaged and is engaged positions. In one
embodiment, catch 574 is configured such that hook 578 is
resiliently biased to or towards the engaged position such that as
end portion 554 is lowered onto pin 572, hook 578 resilient flexes
in a radially outward direction until face 566 is positioned below
hook 578. At such point time, hook 578 resiliently returns to its
natural initial shape so as to overly face 566 to capture end
portion 554 and retain end portion 554. In another embodiment, hook
578 may alternatively need to be manually moved to the engaged
position once end portion 554 has been lowered onto retainer 531.
Catch 574 provides a relatively less complex and low-cost mechanism
for releasably securing end portion 554.
[0085] FIGS. 16-17 illustrate exercise device 620, another
embodiment of exercise device 20 (shown in FIGS. 1-3). Like
exercise device 120, exercise device 620 includes frame 122,
control interface 123, guide 124, foot links 126, and swing arms
128 (each of which are shown in FIGS. 4-6). Exercise device 620 is
similar to exercise device 120 except that exercise device 620
includes connection links 630 (one of which is shown) and frame
retainer 631 in lieu of connection link 130 and frame retainer 131,
respectively. Although not illustrated, exercise device 620 further
includes a foot link retainer substantially identical to frame
retainer 631, but extending from each foot link 126 rather than
frame 122. Like foot link retainer 160, the foot link retainer of
exercise device 620 is configured to engage connection link 630 to
operably couple connection link 630 to the associated foot link
126.
[0086] As shown by FIGS. 16 and 17, connection link 630 is
substantially identical to connection link 130 except that
connection link 630 includes end portion 654 in place of end
portion 154. End portion 654 is configured to releasably connect
link 630 to frame retainer 631 or alternatively to connect
connection link 630 to the foot link retainer (not shown). End
portion 654 includes spherical bearing 664, body 666, catch 668,
sleeve 670 and bias member 672. Spherical bearing 664 rotationally
supports body 666 relative to link 630.
[0087] Body 666 comprises one or more structures extending through
spherical bearing 664. Body 666 includes an internal cavity 671
configured to receive retainer 631, a retainer abutment surface 674
abutting against retainer 631 when body 666 receives retainer 631,
and opening 675 receiving catch 668, a cavity 676 receiving bias
member 672 and a rounded end portion of 678 against which a person
may manually press when moving sleeve 670 along axis 679. In one
embodiment, body 666 is integrally formed as part of a single
unitary body. Another embodiment, body 666 may be formed from
multiple distinct components.
[0088] Catch 668 comprises a resiliently flexible spring formed
from metal or polymeric materials. As shown by FIG. 18, catch 668
includes a flexible band 680, an inwardly extending leg 682 and a
foot 684. Band 680 flexibly supports leg 682 and foot 684. Band 680
is configured so as to permit leg 682 and foot 684 to pivot about
one of more axes provided by the bending or flexing band 680
between and engaged position in which foot 684 extends sufficiently
radially inward so as to engage retainer 631 (as shown in FIG. 17)
and a disengaged position in which leg 682 and foot 684 are
sufficiently withdrawn radially outward to permit withdrawal of
retainer 631 from cavity 672.
[0089] Leg 682 angularly extends from band 680 at an acute angle
and is configured to more easily flex or bend in an upward and
outward word direction (as seen in FIGS. 17 and 18) as compared to
a downward and inward a direction (as seen FIGS. 17 and 18). Foot
684 extends from leg 682 and provides an angled surface against
which retainer 681 engages when retainer 631 is inserted into body
666 and is connected to link 630.
[0090] Sleeve 670 comprises a cylindrical member extending about
body 666 and over catch 675. Sleeve 670 includes an inner
circumferential surface 684 and a circumferential recess 686.
Sleeve 670 is manually movable between a locking state or position
and a released or unlocked state or position. In the locked state
or position shown in FIG. 17, surface 684 overlies catch 675 to
retain leg 682 and foot 684 in the engaged position by inhibiting
pivotal movement of leg 682 and foot 684 in a counter-clockwise
direction (as seen in FIG. 17).
[0091] As shown by FIG. 18, when axially moved in the direction
indicated by arrow 688 towards end portion 678 of body 666 to the
unlocked position, recess 686 overlies catch 675 so as to permit
catch 675 to pivot in a counterclockwise direction about axes
provided by the flexing or bending of band 668 such that leg 682
and foot 684 may pivot to the disengaged position, permitting
withdrawal of retainer 631.
[0092] Retainer 631 comprises along a post coupled to frame 122
which includes a cirque fragile channel 690 and a head portion 692.
Although illustrated as being threadably secured to another shaft
694 which is joined to frame 122, retainer 631 may alternatively be
secured to frame 122 in other fashions. For example, retainer 631
may alternatively be bonded, welded or directly fastened to frame
122.
[0093] During insertion of retainer 631 into cavity 672 and through
spherical bearing 664, head portion 692 engages leg 682 and foot
684 to flex, bend or pivot leg 682 and foot 684 until head portion
692 is above foot 684 (as seen in FIG. 17). As such point time,
foot 684 and leg 680 to resiliently return to their natural shape,
causing foot 684 to be received within groove 690. As a result,
retainer 631 is captured and secured within body 666, connecting
frame 122 to link 630. Insertion of retainer 631 may be achieved
regardless of the positioning of sleeve 670.
[0094] To disconnect link 630 from frame 122, a person, with a
single hand, places end portion 678 against the person's palm or
thumb while the person's fingers pull sleeve 670 in the direction
indicated by 688 against spring 676 until recess 686 is positioned
across from leg 682 of catch 675 as shown in FIG. 18. During
withdrawal of retainer 631, head portion 692 applies forced to
catch 675 causing leg 682 to bend or flex outwardly into recess 686
to the disengaged position. Overall, catch 675 provides an
integrally formed member that facilitates one way insertion of
retainer 631 into cavity 672 of body 666 when sleeve 670 is in
either the locked state or the unlocked state, yet prevents
accidental withdrawal of retainer 631 and disconnection of link 630
while sleeve 670 is in the locked state.
