Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] Not applicable
BACKGROUND
Background and Relevant Art
[0002] In an attempt to improve their health and physical
conditioning, consumers are purchasing home exercise devices in
record quantities. Some of the exercise equipment purchased
includes strength training equipment, such as strength training
systems.
[0003] Strength training systems having one or more exercise
stations linked to a resistance assembly have been around for some
time. Strength training systems are often large and made of
numerous different parts. In order to reduce the cost associated
with packaging, storing, and shipping, strength training systems
are packaged in an unassembled manner. Packaging strength training
systems in an unassembled manner reduces the size of the box
required to enclose the system, thus reducing the packaging costs
and the amount of storage space required to store the system.
[0004] While packaging strength training systems in an unassembled
manner provides some benefits as described above, there are
however, various drawbacks to packaging and shipping strength
training devices is an unassembled manner. For example, when a
strength training system is shipped in an unassembled manner to a
user, the user must assemble the strength training system. Such
assembly can be complicated. Often, strength training systems are
shipped with an instructional manual to assist the user is
assembling the strength training system. However, even with the aid
of an instructional manual, the complications associated with
assembling the strength training system are not eliminated.
Further, the assembled strength training systems often do not
provide the stability or rigidity desired for vigorous strength
training.
[0005] The subject matter claimed herein is not limited to
embodiments that solve any disadvantages or that operate only in
environments such as those described above. Rather, this background
is only provided to illustrate one exemplary technology area where
some embodiments described herein may be practiced.
BRIEF SUMMARY
[0006] In one example, a strength training system includes a
folding frame having a central sub-frame, first and second lateral
sub-frames, and pivoting cross members pivotally coupling the
central sub-frame to at least one of the first and second lateral
sub-frames. The folding frame may be configured to move between an
unfolded position and a folded position in which the first and
second lateral sub-frames are generally parallel in the folded
position and/or in the unfolded position. The strength training
system also includes a strength training assembly coupled to the
folding frame. Strength training assemblies may include, without
limitation, weight machines that make use of pulleys, resistance
bands such as resilient or rubber bands, free weights such as plate
stacks and/or Olympic plates, resilient rods, other types of
resistance and/or some combination of the above. Strength training
assemblies may also include free weights, partial free weight
assemblies, resistance assemblies that make use of a user's weight
and/or some combination of the above. For ease of reference, a
weight machine assembly and a free weight assembly will be
described below. It will be appreciated that these assemblies are
provided for discussion and not by way of limitation.
[0007] In another example, a strength training system includes a
folding frame having a central sub-frame, cross members pivotally
coupled to the central sub-frame and first and second lateral
sub-frames pivotally coupled to the cross members. The folding
frame may be configured to move between an unfolded configuration
and a folded configuration in which at least half of the central
sub-frame is located between the first and second lateral
sub-frames when the folding frame is in the folded configuration
and in which a footprint of the folding frame in the folded
configuration is at least about 80 percent less than the footprint
of the folding frame in the folded configuration, such as about 85
percent less than the footprint of the folding frame in the
unfolded configuration. The strength training system also includes
at least one strength training assembly coupled to the folding
frame.
[0008] In yet another example, a strength training system includes
a folding frame comprising a central sub-frame, cross members
pivotally coupled to the central sub-frame and first and second
lateral sub-frames pivotally coupled to the cross members. The
folding frame being configured to move between an unfolded
configuration and a folded configuration in which the central
sub-frame is located completely between the first and second
lateral sub-frames when the folding frame is in the folded
configuration.
[0009] The strength training system may include a pulley machine
that includes pulleys and cables. In at least one example, the
pulleys and cables may be secured to the folding frame in a
pre-assembled manner. Further, in at least one example, the
strength training system may be assembled without the use of
tools.

DETAILED DESCRIPTION
[0022] A folding frame assembly is provided herein, which may be
part of a strength training system. The folding frame assembly is
configured to be readily moved from a folded or collapsed position.
In at least one example, the folding frame assembly includes
several sub-frames that are coupled together with pivoting cross
members. The pivoting cross members allow the sub-frames to be
collapsed together while providing a stable platform for strength
training equipment when the folding frame assembly is unfolded.
Accordingly, the pivoting cross members allow the folding frame
assembly to be nearly completely assembled, which may reduce the
complexity of assembling the exercise system. Further, the
configuration of the folding frame assembly allows the folding
frame assembly to have a folded footprint that is at least about 70
percent less than the expanded footprint, such as at least about 80
percent less than the expanded footprint, e.g., about 85 percent
less. Such a configuration may allow the folding frame assembly to
be shipped while nearly completely assembled. Other configurations
may provide for an even further reduction of the folded footprint
relative to the expanded footprint.
[0023] FIG. 1A is a perspective view of a strength training system
10 that includes a folding frame assembly 100 as well as one or
more strength training assembly, which may include a weight machine
such as a pulley machine 200, and/or a free-weight assembly 300. As
will be discussed in more detail below, the folding frame assembly
100 allows the strength training system 10 to be moved between an
expanded configuration as illustrated in FIG. 1A to a folded
configuration as illustrated in FIG. 1B.
[0024] As seen in FIGS. 1A and 1B, folding the strength training
system 10 reduces the footprint of the strength training system 10.
As used herein, the term footprint shall be broadly understood to
mean the surface area which is covered by a line which extends
vertically from the outer most portions of the exercise system
while the exercise system is in a given configuration, such as an
expanded configuration and a folded or collapsed configuration.
[0025] In at least one example, the configuration of the folding
frame assembly reduces the footprint of the strength training
system in the expanded configuration relative to the folded
configuration by approximately 70 percent. As used herein, the term
footprint shall be broadly understood as the longest width
dimension of the folding frame assembly 100 multiplied by the
longest length dimension of the folding frame assembly 100 when
viewed in a plan view. Thus, from a top view looking downward on
assembly 100, the folded footprint is substantially smaller than
the unfolded footprint.
[0026] In one example, a footprint of the folding frame in the
folded configuration is at least about 70 percent less than the
footprint of the folding frame in the unfolded configuration. In
another example, a footprint of the folding frame in the folded
configuration is at least about 75 percent less than the footprint
of the folding frame in the unfolded configuration. In yet another
example, the footprint of the folding frame in the folded
configuration is at least about 80 percent less than the footprint
of the folding frame in the unfolded configuration. In still
another example, the footprint of the folding frame in the folded
configuration is at least about 85 percent less than the footprint
of the folding frame in the unfolded configuration.
[0027] Such a configuration may allow the strength training system
to occupy a relatively small area, such as when the strength
training system is packed for shipping or when the system is stored
or not in use. Further, the folding frame assembly 100 may also
allow a user to rapidly move the folding frame assembly 100 from a
folded configuration to an expanded configuration rapidly and to
secure folding frame assembly 100 in place to form a stable
platform for the strength training system 100.
[0028] With continuing reference to FIG. 1A, the folding frame
assembly includes a central sub-frame 102 as well as first and
second lateral sub-frames 104 and 106 respectively. The central
sub-frame 102 includes a front vertical support 108, a rear
vertical support 110, an upper support 112, as well as a lower
support 114. The upper and lower supports 110, 112 couple the front
vertical support 108 and the rear vertical support 110.
[0029] In at least one example, the first lateral sub-frame 104
includes front and rear vertical supports 116, 118 that are secured
together with upper and lower supports 120, 122. The second lateral
sub-frame 106 may be substantially similar to the first lateral
sub-frame 104. Accordingly, the second lateral sub-frame 106 may
also include front and rear vertical supports 124, 126 that are
coupled together with upper and lower supports 128, 130.
[0030] The central sub-frame 102 is operatively associated with
each of the first lateral sub-frame 104 and the second lateral
sub-frame 106. In particular, the folding frame assembly 100 may
include upper and lower pivoting cross members 132, 134 that couple
the central sub-frame 102 to the first lateral sub-frame and/or
upper and lower pivoting cross members 136, 138 that couple the
central sub-frame 102 to the second lateral sub-frame 104. In at
least one example, a single lateral sub-frame is pivotally secured
to the central sub-frame 102 while another lateral sub-frame may be
secured to the central sub-frame in some other manner. For ease of
reference, the first and second lateral sub-frames 102, 104 will be
described in the context of each being pivotally coupled to the
central sub-frame 102.
[0031] More particularly, the folding frame assembly 100 includes
several pivot assemblies 140. As illustrated in FIG. 1A, the
folding frame assembly 100 include pivot assemblies 140 that couple
the front vertical support 108 of the central sub-frame to upper
and lower pivoting cross members 132, 134 as well as to upper and
lower pivoting cross members 136, 138. Pivot assemblies 140 also
couple upper and lower pivoting cross members 132, 134 to the rear
vertical support 118 of the first lateral sub-frame 102 as well as
coupling the upper and lower pivoting cross members 136, 138 to the
rear vertical support 126 of the second lateral sub-frame 104. In
at least one example, each of the pivot assemblies 140 is similar.
In other examples, the pivot assemblies 140 may be configured
differently from each other. As will be discussed in more detail
below, each pivot assembly 140 allows the pivoting cross members
132-138 to pivot relative to the corresponding vertical support
member and to secure each pivoting cross member in a desired
position relative to a corresponding vertical cross member.
[0032] FIG. 1C illustrates a pivot assembly 140 in more detail. The
pivot assembly 140 illustrated in FIG. 1C will be discussed with
respect to coupling the upper pivoting cross member 132 to the rear
vertical support 118 of the first lateral sub-frame 104. It will be
appreciated that a discussion of the pivot assembly 140 may apply
to the other vertical supports and pivoting cross members.
[0033] The pivot assembly 140 generally includes a channeled
support 142 and a pivot pin 144. The channeled support 142 may be
secured to the rear vertical support 118. The channeled support 142
may also be integrally formed with the rear support 118. Further,
portions of the channeled support 142 may be integrally formed with
the rear vertical support 118 and/or integrally formed with the
lower pivoting cross member 134.
[0034] In any case, the channeled support 142 may include opposing
portions including a top portion 146 and a bottom portion 148
located on opposing sides of a central portion 150. The channeled
support 142 includes guide holes defined in both the top and bottom
portions 146, 148 that correspond to similar holes defined in the
upper pivoting cross member 132. The pivot pin 144 extends through
the top portion 146, through the upper pivoting cross member 132,
and out of the lower portion 148 of the channeled support 142. The
pivot pin 144 may be secured in position by any suitable means,
such as by a nut secured to the end of the pivot pin 144. In other
examples, the pivot pin 144 may have a different configuration,
such as having a cotter pin type configuration or other
configuration.
[0035] Accordingly, the configuration of the channeled support 142
allows the upper pivoting cross member 132 to pivot away from the
central portion 150 of the pivot assembly 140 while preventing the
upper pivoting cross member 132 from pivoting past the central
portion 150. As illustrated in FIG. 1D, the channeled support 142
also includes a hole 152 defined in the central portion 150 of the
channeled support 142.
[0036] An additional hole is defined in the lower pivoting cross
member 134. In one example, the hole defined in the upper pivoting
cross member 132 may be threaded. When the lower pivoting cross
member 134 is brought into contact with the central portion 150,
the holes discussed above are brought into alignment. Once the
holes are brought into alignment, a fastener, such as a bolt, may
engage the threads in the lower pivoting cross member 134 to
thereby secure the upper pivoting cross member 132 in position
relative to the pivot assembly 140 and thus secure the upper
pivoting cross member 132 in position relative to the rear vertical
support 118.
[0037] Accordingly, the pivot assembly 140 allows a pivoting cross
member to move from a folded configuration to an expanded
configuration. Pivot assemblies 140 further allow pivoting cross
members to be rapidly secured in the expanded configuration
relative to a corresponding vertical support member. The pivoting
cross members will now be discussed to describe the folding of the
folding frame assembly 100.
[0038] With reference again to FIG. 1A, while the folding frame
assembly 100 is in the expanded configuration, the first and second
lateral sub-frames 104, 106 and the pivoting cross members 132-138
form a structure having a generally rectangular footprint such that
the folding frame assembly 100 has a generally boxed shape
configuration. In such a configuration, more than half of the
central sub-frame is outside of the box formed by the first and
second lateral sub-frames 104, 106 and the pivoting cross members
132-138. For example, all but the front vertical support 112 may be
exterior to the first and second lateral sub-frames 104, 106 when
the folding frame assembly 100 is in the expanded
configuration.
[0039] In at least one example, the folding frame assembly 100 has
an expanded footprint that is about 57 inches to about 62.7 inches
in length by about 50 inches in width, (such as a length of about
62.7 inches and a width of about 50 inches, for example). The
folding frame assembly 100 may have a folded footprint of about 37
inches in length and about 11.5 inches in width, for example. Such
a configuration may result in a footprint of about 3,135 square
inches in the expanded configuration and a footprint of about 442.5
square inches in the folded configuration. Such a configuration may
result in a reduction in the footprint of more than 80 percent,
such as about 85 percent, about 86 percent, or more.
[0040] As illustrated in FIG. 1B, when the folding frame assembly
100 is in a folded configuration, more than half of the central
sub-frame 102 is between the first and second lateral sub-frames
104, 106. In addition, the central sub-frame 102 may be completely
between the first and second lateral sub-frames 104, 106 when the
folding frame assembly 100 is in the folded or collapsed
configuration. Further, any number of the components of the folding
frame assembly 100, such as different portions of the central
sub-frame 102, the first and second lateral sub-frames 104, 106,
and/or the pivoting cross members 132-138 may telescope to further
reduce the size of the folding frame assembly 100 in the folded
configuration.
[0041] In one example, the folding frame assembly 100 is unfolded
by moving the first and second lateral sub-frames 104, 106 away
from the central sub-frame 102. As previously discussed, the first
and second lateral sub-frames 104, 106 may be moved away from the
central sub-frame 102 by moving the lateral sub-frames 104, 106
until the pivoting cross members 132-138 engage the central
portions 150 (FIG. 1C) of the pivot assemblies 140. Once in such a
position, the first and second lateral frames 104, 106 and the
pivoting cross members 132-138 may be secured in the expanded
position illustrated in FIG. 1A.
[0042] As illustrated in FIGS. 1A and 1B, the first and second
lateral sub-frames 104, 106 may be approximately parallel to each
other in each of the folding and expanded or unfolded
configurations. Further, the first and second lateral sub-frames
104, 106 may be approximately parallel to the central sub-frame 102
in each of the folded and expanded configurations.
[0043] Accordingly, the first and second lateral sub-frames 104,
106 are pivoted into the expanded positions relative to the central
sub-frame 102. Thereafter, a removable cross member 152 may be
secured to the device to thereby further secure the front vertical
supports 116, 124 in position relative to each other.
[0044] In particular, as illustrated in FIG. 1A the front vertical
supports 116, 124 may have channeled supports 156, 158 secured
thereto. Each of the channeled supports 156, 158 may be
substantially similar. Accordingly, reference will be made to
channeled support 156 in particular. The discussion of the
channeled support 156 may also apply to channeled support 158.
[0045] The channeled support 156 includes a central portion 160
that corresponds to a bottom of the channeled support 156 as well
as side portions 162 that correspond to the sides. In at least one
example, the channeled support 156 includes a hole defined therein.
The removable cross member 152 may include a corresponding hole
defined therein. The hole defined in the removable cross member 152
may be threaded or have a threaded member secured to the interior
thereof adjacent the hole.
[0046] In either case, the holes defined in the removable cross
member 152 and the channeled support 156 may be aligned when the
removable cross member 152 is located within the channeled support
156. Once the removable cross member 152 is thus coupled to the
channeled support 156, a fastener, such as a bolt or other
fastener, may be passed through the holes described above to engage
the holes. Accordingly, the removable cross member 152 may be
secured to the channeled support 156. The channeled support 156 in
turn is secured to the front vertical support 116. In another
example, a portion or all of the channeled support 156 may be
integrally formed with the front vertical support 116 and/or the
channeled support 156.
[0047] The removable cross member 152 may be substantially rigid.
Accordingly, securing the removable cross member 152 to the front
vertical supports 116, 124 constrains the distance between the
front vertical supports 116, 124, thereby further securing the
relationship between the first and second lateral sub-frames 104,
106. Further constraining the relationship between the first and
second lateral sub-frames 104, 106 the removable cross member 152
further stabilizes the folding frame assembly 100 in the expanded
configuration. In at least one example, the removable cross member
152 may be used to stabilize the folding frame in the expanded or
use configuration to allow the strength training system 10 to be
assembled without the use of tools. Accordingly, the folding frame
assembly 100 provides a highly collapsible and readily unfolded
frame that is configured to provide a stable platform for a weight
machine and/or free weights, as will be described in more detail
below.
[0048] FIG. 2A illustrates a partial view of a weight machine, such
as the pulley machine 200. The pulley machine 200 includes a weight
rack 202 that is secured to front and rear guide rails 204, 206.
The front and rear guide rails 204, 206 are secured to the central
sub-frame 102. In particular, the front and rear guide rails 204,
206 may form the rear vertical support 110. The front and rear
guide rails 204, 206 extend at least partially from the lower
support 114 toward the upper support 112 and may extend from the
lower support 114 to the upper support 112. The front and rear
guide rails 204, 206 allow the weight rack 202 to be raised and
lowered by the pulley machine 200 to thereby provide resistance for
strength training applications.
[0049] The pulley machine 200 includes pulleys and cables to
provide various strength training applications that use the weight
rack 202 and weights associated with the weight rack 202 for
resistance. The configuration of the strength training system 10
allows the pulley machine 200 to be pre-assembled to the folding
frame assembly 100, such as before the strength training system 10
is shipped to a customer. Such a configuration may decrease the
assembly time of the strength training system 10 by reducing the
number of operations a consumer would perform in order to fully
assemble the strength training system. In at least one example, the
pulley machine 200 includes an upper pulley assembly 208 and a
lower pulley assembly 210.
[0050] The upper pulley assembly 208 includes first, second, and
third pulleys 212, 214, 216 as well as first and second coupler
pulley assemblies 218, 220 respectively. The lower pulley assembly
210 includes first, second, third, fourth fifth, and sixth pulleys
222, 223, 224, 225, 226, and 227 as well as a third coupler pulley
assembly 230.
[0051] A first cable 228 is secured to the weight rack 202.
Movement of the first cable 228 results in movement of the weight
rack 202. The first cable 228 extends from the weight rack 202 and
over the first pulley 212. The first cable 228 then extends from
the first pulley 212, over the second pulley 214 without engaging
the second pulley 214, and into engagement with the third pulley
216. The first cable 228 then extends downward and into engagement
with the first coupler pulley assembly 218.
[0052] The first coupler assembly 218 includes an upper pulley 232
and a lower pulley 234 which are each coupled to a frame 236. In
the illustrated example, the frame 236 includes opposing plates.
Regardless of the configuration of the frame 236, the first coupler
pulley assembly 218 allows the upper pulley 232 and the lower
pulley 234 to rotate independently of each other, such as to allow
independent rotation of cables or cable segments coupled to each of
the pulleys 232, 234 while coupling the position of the pulleys
232, 234.
[0053] The first cable 228 is wrapped around the upper pulley 232
and then extends upwardly to the second upper pulley 214. From the
second upper pulley 214, the first cable 228 extends downward to
where the first cable 228 is secured to the second coupler pulley
assembly 220.
[0054] A second cable 238 passes through the lower pulley 234 of
the first coupler pulley assembly 218. In particular, the second
cable 238 may be anchored to the lower support 114 and pass over
the lower pulley 234. From the lower pulley 234, the second cable
238 is directed to the first pulley 222 of the lower pulley
assembly 210.
[0055] From the first pulley 222, the second cable 238 passes
through the third coupler pulley assembly 230. In particular, the
third coupler assembly 230 includes a frame 240 that has a lower
pulley 242 and an upper pulley 243. The second cable 238 is
operatively associated with the lower pulley 242. From the lower
pulley 242, the second cable 238 is directed to the second pulley
224 of the lower pulley assembly 210. The second cable 238 may
include an attachment point secured thereto for performing strength
training exercises. As introduced, the third coupler assembly 230
includes an upper pulley 243 operatively associated with the frame
240. A third cable 245 is operatively associated with the upper
pulley 243. The third cable 245 extends from the upper pulley 243
to a fly machine 247.
[0056] FIG. 2B illustrates the fly machine 247 in more detail. The
fly machine 247 may include a mounting bracket 248, fly arms 250,
252, and tabs 254, 256. The fly arms 250, 252 are pivotingly
coupled to the mounting bracket 248. The tabs 254, 256 are also
operatively associated with fly arms 250, 252 respectively as well
as the mounting bracket 248. In the illustrated example, the fly
arms 250, 252 selectively engage the tabs 254, 256. More
specifically, as the fly arms 250, 252 rotate away from the central
sub-frame 102, the fly arms 250, 252 engage the tabs 254, 256. As
the fly arms 250, 252 rotated toward the central sub-frame 102,
such as may be the case when the fly arms 250, 252 are folded for
storage.
[0057] The fly arms 250, 252 engage the tabs 254, 256 such that the
tabs 254, 256 follow the tabs 254, 256 at an angle, such as
approximately 90 degrees. The tabs 254, 256 include holes 258
defined therein that are configured to receive a cable, such as the
third cable 245.
[0058] As previously introduced, the third coupler pulley assembly
230 splits the third cable 245. The ends of the third cable 245 are
routed from the third coupler pulley assembly 230 to first and
second pulleys 268, 270 associated with the fly machine 247. The
first and second pulleys 268, 270 route the ends of the third cable
245 to the tabs 264, 266. Accordingly, as the fly arms 250, 252
engage the tabs 264, 266 to move the tabs 264, 266 away from the
central sub-frame 102 the tabs 264, 266 pull the third cable
245.
[0059] As previously introduced, movement of the third cable 245 is
coupled to the first cable 228 by way of the pivot assemblies and
the second cable 238 as described above. Accordingly, as the fly
arms 250, 252 are moved away from the central sub-frame 102 the
tabs 264, 266 pull the third cable 245 to pull the first cable 228
to lift the weight rack 202.
[0060] The fly arms 250, 252 include adjustable arm rests 272, 274.
The adjustable arm rests 272, 274 are configured to translate
relative to the fly arms 250, 252. FIG. 2C illustrates a partial
cross sectional view of the fly arm 250 and the adjustable arm rest
256. The fly arm 250 may extend at least partially through the
adjustable arm rest 272. The fly arm 250 may include a series of
holes 275 defined therein to provide selected positions at which
the adjustable arm rest 272 may be secured. Accordingly, the
adjustable arm rest 272 may include a securing feature 276. The
securing feature 276 illustrated in FIG. 2C includes a knob 278
that is secured to a shaft 280. The shaft 280 includes a threaded
portion 282 and pin portion 284.
[0061] The threaded portion 282 is configured to engage a threaded
portion 286 which may be secured to the adjustable arm rest 256 to
thereby secure the adjustable arm rest 256 in position relative to
the fly arm 250. In particular, as the threaded portion 282 of the
shaft 280 is threaded into threaded portion 286 of the adjustable
arm rest 272, the pin portion 284 extends through the corresponding
hole 275 in the fly arm 250 to thereby secure the adjustable arm
rest 272 in position relative to the fly arm 250. Accordingly, the
fly machine 247 includes adjustable arm rests 272, 274 to allow
users having various arm lengths to use the fly machine 247 as
described above.
[0062] As previously introduced the first cable 228 passes over the
first and third pulleys 212, 216 to the first coupler pulley
assembly 218, around the second pulley 214 and to the second
coupler pulley assembly 220. The second coupler pulley assembly 220
includes a frame 290 and a pulley 291 coupled to the frame 290. The
first cable 228 is secured to the frame 290. A fourth cable 292 is
operatively associated with the pulley 291. In particular, the
pulley 291 splits the fourth cable 292, which runs from the pulley
291 to the third and fourth pulleys 224, 225 of the lower pulley
assembly 210. The fourth cable 292 is directed from the third and
fourth pulleys 224, 225 to fifth and sixth pulleys 226, 227
respectively.
[0063] The fifth and sixth pulleys 226, 227 may be secured to the
lower supports 122, 130 of the lateral sub-frames 104, 106. The
fifth and sixth pulleys 226, 227 direct the fourth cable 292 to
additional pulleys 293, 294 that are coupled to upper supports 112,
120. Pulleys 293, 294 direct the fourth cable 292. In one example,
the fourth cable 292 is routed internally through the upper
supports 112, 120 to pivoting pulleys 293, 294. Each of the ends of
the fourth cable 292 may include an attachment point secured
thereto for performing strength training exercises.
[0064] Turning now briefly to FIGS. 1A and 1B, when the folding
frame assembly 100 is folded, the pulley machine 200 is
substantially contained by the folding frame assembly 100. Further,
while the folding frame assembly 100 is expanded, the folding frame
assembly 100 provides a stable platform for the components of the
pulley machine 200.
[0065] In addition to providing a stable platform for the pulley
machine 200, the folding frame assembly 100 also provides a stable
platform for additional strength training equipment, such as a free
weight assembly 300. FIG. 3A illustrates a perspective view of the
strength training system 10 that focuses on the free weight
assembly 300.
[0066] The free weight assembly 300 may include, without
limitation, a pull-up bar 302, a weight rack assembly 304, a weight
crutch assembly 306, and a smith machine 308. The pull up bar 302
may be part of the removable cross member 154 discussed in more
detail with reference to FIGS. 1A and 1B. In the illustrated
example the pull up bar 302 may include two individual bar portions
310, 312. Each of the bar portions 310, 312 may be shaped to
provide a variety of hand positions. Accordingly, the pull up bar
302 may be provided with the removable cross member 154.
[0067] The free weight assembly 300 also includes the weight rack
assembly 304. The weight rack assembly 304 may include a plurality
of posts 314 that are removably secured to the folding frame
assembly 100. In particular, the posts 314 may be secured to the
rear vertical supports 118, 126 of each of the lateral sub-frames
104, 106. Each of the rear vertical supports 118, 126 include a
plurality of holes defined therein as well as threaded portions
associated with the holes. In one example, the holes have threaded
portions defined therein. Each of the posts may include a threaded
portion that is configured to engage the threads associated with
the holes defined in the rear vertical supports 118, 126. Such a
configuration may allow a user to readily secure the posts 314 to
the rear vertical supports 118, 126 while allowing a user to
readily remove the posts 314 to reduce the foot print of the
strength training system 10 when the folding frame assembly 100 is
collapsed, such as for shipping and/or long term storage.
[0068] The posts 314 are configured to store free weights, such as
Olympic plates, on the folding frame assembly 100. Such weights may
be utilized with the weight rack 202 associated with the pulley
machine 200. The weights may also be utilized with one or more bars
in conjunction with the weight crutch assembly 306 and/or the Smith
machine 308, which will now be discussed in turn.
[0069] The weight crutch assembly 306 includes slotted rails 316,
318, lower weight crutches 320, 322 and upper weight crutches 324,
326. The lower weight crutches 320, 322 may be longer than the
upper weight crutches 324, 326. Both the lower and upper weight
crutches 320, 322 are configured to support a bar.
[0070] The slotted rails 316 include a plurality of slots 328. The
weight crutches 320-326 are configured to selectively engage the
slots 328. In one example, the weight crutches 320-326 may
interface with slots 328 in a substantially similar manner.
Accordingly, a discussion of the interaction between lower weight
crutch 320 may be applied to the interaction to the other weight
crutches 322-326 and the slots.
[0071] FIG. 3B illustrates lower weight crutch 320 in isolation.
With reference to FIG. 3B and simultaneous reference to FIG. 3A,
the lower weight crutch 320 includes a tab 330 having a width
aspect that is approximately the same size as a height aspect of
the slots 328 (FIG. 3A). Further, the tab 330 may have a height
aspect that is similar to a width aspect of the slots 328. Such a
configuration may allow the tab 330 to be secured to a slot 328 by
aligning the width aspect of the tab 330 to the height aspect of
the slot 328 and the height aspect of the tab 330 to the width
aspect of the slot 328 to allow the tab 330 to be placed within the
slot 328.
[0072] Thereafter, the lower weight crutch 320 may be rotated.
Since the width aspect of the tab 330 is greater than the width
aspect of the slot 328, the lower weight crutch 320 is thereby
selectively secured to the slotted rail 316. The lower weight
crutch 320 may be removed by following the steps above in reverse
order. The lower weight crutch 320 may then be moved to a desired
slot and secured to that slot.
[0073] Accordingly, the weight crutches 320 may be moved to desired
positions, such as positions corresponding to positions for
supporting a bar. By positioning the weight crutches 320-326 in
appropriate positions, the weight crutches 320-326 may provide
supports for a bar to be used in which only the vertical position
is constrained during weight lifting exercises while allowing some
degree of freedom in the horizontal direction.
[0074] The free weight assembly 300 also includes the Smith machine
type assembly 308 previously introduced. The Smith machine 308 may
include tubular guides 332, 334 that extend from the lower supports
122, 130 to the upper supports 120, 128. The Smith machine 308 also
includes slotted rail coupled to the front vertical supports 116,
126, lower latch assemblies 340, 342, and upper latch assemblies
344, 346. The lower latch assemblies 340, 342 are configured to
translate vertically relative to the tubular guide rails 332, 334
and to engage the slotted rails 336, 338 to secure the lower latch
assemblies 340, 342 at desired locations. Such a configuration may
allow the lower latch assemblies 340, 342 to limit the vertical
movement of the upper latch assemblies 344, 346.
[0075] The upper latch assemblies 344, 346 may be configured to
engage the slotted rails 336, 338 in a similar manner as the lower
latch assemblies 340, 342. Further, the upper latch assemblies 344,
346 may include linear bearings which engage the tubular guide
rails 332, 334. In addition, the upper latch assemblies 344, 346
may include bar supports 348, 350. The bar supports 348, 350 are
configured to receive an Olympic bar 352. In particular, the
Olympic bar 352 includes a central portion 354 that may be passed
through the bar supports 348, 350. The ends of the central portion
354 may include threaded ends that are configured to receive weight
supports 356, 358. Accordingly, once the central portion 354 has
been passed through the bar supports 348, 350, the weight supports
356, 358 may be secured to the Olympic bar 352 on the outside of
the bar supports 348, 350. Such a configuration allows the Olympic
bar 352 to be secured to the upper latch assembly 342, 344. The
location of the upper latch assembly 342, 344 in turn is
constrained horizontally by the tubular guide rails 332, 334 and
vertically by the lower latch assemblies 340, 342. Such a
configuration may allow a user to lift weights in a secure and
stable manner to reduce the possibility of injury from dropping
weights while performing weight lifting exercises using the Smith
machine 308. Accordingly, the strength training system 10 includes
a folding frame assembly 100 that provides a stable platform for a
weight machine and/or free weights.
[0076] A folding frame assembly has been provided herein, which may
be part of a strength training system. The folding frame assembly
is configured to be readily moved from a folded or collapsed
position. In at least one example, the folding frame assembly
includes several sub-frames that are coupled together with pivoting
cross members. The pivoting cross members allow the sub-frames to
be collapsed together while providing a stable platform for
strength training equipment when the folding frame assembly is
unfolded. Accordingly, the pivoting cross members allow the folding
frame assembly to be nearly completely assembled, which may reduce
the complexity of assembling the exercise system. Further, the
configuration of the folding frame assembly allows the folding
frame assembly to have a folded footprint that is at least about 80
percent less than the expanded footprint, such as about 85 percent
less. Such a configuration may allow the folding frame assembly to
be shipped while nearly completely assembled.
[0077] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative and not restrictive. The scope of
the invention is, therefore, indicated by the appended claims
rather than by the foregoing description. All changes that come
within the meaning and range of equivalency of the claims are to be
embraced within their scope.
