Definitions
- 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.
- 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.
- 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.
- strength training systems are shipped with an instructional manual to assist the user is assembling the strength training system.
- the complications associated with assembling the strength training system are not eliminated.
- the assembled strength training systems often do not provide the stability or rigidity desired for vigorous strength training.
- 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.
- 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.
- a strength training system in another example, 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.
- a strength training system in yet another example, 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.

- 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.
- 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.
- 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.
- 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 .
- 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 .
- folding the strength training system 10 reduces the footprint of the strength training system 10 .
- 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.
- 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.
- 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.
- the folded footprint is substantially smaller than the unfolded footprint.
- 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.
- 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 .

- 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 .
- the central sub-frame 102 is operatively associated with each of the first lateral sub-frame 104 and the second lateral sub-frame 106 .
- 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 .

- 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 .
- each of the pivot assemblies 140 is similar.
- the pivot assemblies 140 may be configured differently from each other.
- 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.
- 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.

- the pivot pin 144 may have a different configuration, such as having a cotter pin type configuration or other configuration.
- 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 .
- the channeled support 142 also includes a hole 152 defined in the central portion 150 of the channeled support 142 .
- An additional hole is defined in the lower pivoting cross member 134 .
- the hole defined in the upper pivoting cross member 132 may be threaded.
- 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 .
- 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 .
- 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.

- 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.
- the central sub-frame 102 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 .
- 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.
- 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.

- first and second lateral sub-frames 104 , 106 are pivoted into the expanded positions relative to the central sub-frame 102 .
- 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.
- 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 .

- 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 .
- 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 .
- 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.

Description
- Not applicable
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- Additional features and advantages will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the teachings herein. Features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
- In order to describe the manner in which the above-recited and other advantages and features can be obtained, a more particular description of the subject matter briefly described below will be rendered by reference to specific embodiments which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments and are not therefore to be considered to be limiting in scope, embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

FIG. 3A illustrates a free weight assembly coupled to a folding frame according to one example; and -
FIG. 3B illustrates a weight crutch according to one example. - 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.
-
FIG. 1A is a perspective view of astrength training system 10 that includes afolding frame assembly 100 as well as one or more strength training assembly, which may include a weight machine such as apulley machine 200, and/or a free-weight assembly 300. As will be discussed in more detail below, thefolding frame assembly 100 allows thestrength training system 10 to be moved between an expanded configuration as illustrated inFIG. 1A to a folded configuration as illustrated inFIG. 1B . - As seen in
FIGS. 1A and 1B , folding thestrength training system 10 reduces the footprint of thestrength 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. - 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 thefolding frame assembly 100 when viewed in a plan view. Thus, from a top view looking downward onassembly 100, the folded footprint is substantially smaller than the unfolded footprint. - 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.
- 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 thefolding frame assembly 100 from a folded configuration to an expanded configuration rapidly and to securefolding frame assembly 100 in place to form a stable platform for thestrength training system 100. - With continuing reference to
FIG. 1A , the folding frame assembly includes acentral sub-frame 102 as well as first and secondlateral sub-frames central sub-frame 102 includes a frontvertical support 108, a rearvertical support 110, anupper support 112, as well as alower support 114. The upper andlower supports vertical support 108 and the rearvertical support 110. - In at least one example, the first
lateral sub-frame 104 includes front and rearvertical supports lower supports lateral sub-frame 106 may be substantially similar to the firstlateral sub-frame 104. Accordingly, the secondlateral sub-frame 106 may also include front and rearvertical supports lower supports - The
central sub-frame 102 is operatively associated with each of the firstlateral sub-frame 104 and the secondlateral sub-frame 106. In particular, thefolding frame assembly 100 may include upper and lowerpivoting cross members central sub-frame 102 to the first lateral sub-frame and/or upper and lowerpivoting cross members central sub-frame 102 to the secondlateral sub-frame 104. In at least one example, a single lateral sub-frame is pivotally secured to thecentral 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 secondlateral sub-frames central sub-frame 102. - More particularly, the
folding frame assembly 100 includesseveral pivot assemblies 140. As illustrated inFIG. 1A , thefolding frame assembly 100 includepivot assemblies 140 that couple the frontvertical support 108 of the central sub-frame to upper and lowerpivoting cross members pivoting cross members Pivot assemblies 140 also couple upper and lowerpivoting cross members vertical support 118 of the firstlateral sub-frame 102 as well as coupling the upper and lowerpivoting cross members vertical support 126 of the secondlateral sub-frame 104. In at least one example, each of thepivot assemblies 140 is similar. In other examples, thepivot assemblies 140 may be configured differently from each other. As will be discussed in more detail below, eachpivot 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. -
FIG. 1C illustrates apivot assembly 140 in more detail. Thepivot assembly 140 illustrated inFIG. 1C will be discussed with respect to coupling the upperpivoting cross member 132 to the rearvertical support 118 of the firstlateral sub-frame 104. It will be appreciated that a discussion of thepivot assembly 140 may apply to the other vertical supports and pivoting cross members. - The
pivot assembly 140 generally includes a channeled support 142 and apivot pin 144. The channeled support 142 may be secured to the rearvertical support 118. The channeled support 142 may also be integrally formed with therear support 118. Further, portions of the channeled support 142 may be integrally formed with the rearvertical support 118 and/or integrally formed with the lowerpivoting cross member 134. - In any case, the channeled support 142 may include opposing portions including a
top portion 146 and abottom portion 148 located on opposing sides of acentral portion 150. The channeled support 142 includes guide holes defined in both the top andbottom portions pivoting cross member 132. Thepivot pin 144 extends through thetop portion 146, through the upperpivoting cross member 132, and out of thelower portion 148 of the channeled support 142. Thepivot pin 144 may be secured in position by any suitable means, such as by a nut secured to the end of thepivot pin 144. In other examples, thepivot pin 144 may have a different configuration, such as having a cotter pin type configuration or other configuration. - Accordingly, the configuration of the channeled support 142 allows the upper
pivoting cross member 132 to pivot away from thecentral portion 150 of thepivot assembly 140 while preventing the upperpivoting cross member 132 from pivoting past thecentral portion 150. As illustrated inFIG. 1D , the channeled support 142 also includes ahole 152 defined in thecentral portion 150 of the channeled support 142. - An additional hole is defined in the lower
pivoting cross member 134. In one example, the hole defined in the upperpivoting cross member 132 may be threaded. When the lowerpivoting cross member 134 is brought into contact with thecentral 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 lowerpivoting cross member 134 to thereby secure the upperpivoting cross member 132 in position relative to thepivot assembly 140 and thus secure the upperpivoting cross member 132 in position relative to the rearvertical support 118. - 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 thefolding frame assembly 100. - With reference again to
FIG. 1A , while thefolding frame assembly 100 is in the expanded configuration, the first and secondlateral sub-frames 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 secondlateral sub-frames vertical support 112 may be exterior to the first and secondlateral sub-frames folding frame assembly 100 is in the expanded configuration. - 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). Thefolding 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. - As illustrated in
FIG. 1B , when thefolding frame assembly 100 is in a folded configuration, more than half of thecentral sub-frame 102 is between the first and secondlateral sub-frames central sub-frame 102 may be completely between the first and secondlateral sub-frames folding frame assembly 100 is in the folded or collapsed configuration. Further, any number of the components of thefolding frame assembly 100, such as different portions of thecentral sub-frame 102, the first and secondlateral sub-frames folding frame assembly 100 in the folded configuration. - In one example, the
folding frame assembly 100 is unfolded by moving the first and secondlateral sub-frames central sub-frame 102. As previously discussed, the first and secondlateral sub-frames central sub-frame 102 by moving thelateral sub-frames FIG. 1C ) of thepivot 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 inFIG. 1A . - As illustrated in
FIGS. 1A and 1B , the first and secondlateral sub-frames lateral sub-frames central sub-frame 102 in each of the folded and expanded configurations. - Accordingly, the first and second
lateral sub-frames central sub-frame 102. Thereafter, aremovable cross member 152 may be secured to the device to thereby further secure the frontvertical supports - In particular, as illustrated in
FIG. 1A the frontvertical supports supports support 156 in particular. The discussion of the channeledsupport 156 may also apply to channeledsupport 158. - The channeled
support 156 includes acentral portion 160 that corresponds to a bottom of the channeledsupport 156 as well asside portions 162 that correspond to the sides. In at least one example, the channeledsupport 156 includes a hole defined therein. Theremovable cross member 152 may include a corresponding hole defined therein. The hole defined in theremovable cross member 152 may be threaded or have a threaded member secured to the interior thereof adjacent the hole. - In either case, the holes defined in the
removable cross member 152 and the channeledsupport 156 may be aligned when theremovable cross member 152 is located within the channeledsupport 156. Once theremovable cross member 152 is thus coupled to the channeledsupport 156, a fastener, such as a bolt or other fastener, may be passed through the holes described above to engage the holes. Accordingly, theremovable cross member 152 may be secured to the channeledsupport 156. The channeledsupport 156 in turn is secured to the frontvertical support 116. In another example, a portion or all of the channeledsupport 156 may be integrally formed with the frontvertical support 116 and/or the channeledsupport 156. - The
removable cross member 152 may be substantially rigid. Accordingly, securing theremovable cross member 152 to the frontvertical supports vertical supports lateral sub-frames lateral sub-frames removable cross member 152 further stabilizes thefolding frame assembly 100 in the expanded configuration. In at least one example, theremovable cross member 152 may be used to stabilize the folding frame in the expanded or use configuration to allow thestrength training system 10 to be assembled without the use of tools. Accordingly, thefolding 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. -
FIG. 2A illustrates a partial view of a weight machine, such as thepulley machine 200. Thepulley machine 200 includes aweight rack 202 that is secured to front andrear guide rails rear guide rails central sub-frame 102. In particular, the front andrear guide rails vertical support 110. The front andrear guide rails lower support 114 toward theupper support 112 and may extend from thelower support 114 to theupper support 112. The front andrear guide rails weight rack 202 to be raised and lowered by thepulley machine 200 to thereby provide resistance for strength training applications. - The
pulley machine 200 includes pulleys and cables to provide various strength training applications that use theweight rack 202 and weights associated with theweight rack 202 for resistance. The configuration of thestrength training system 10 allows thepulley machine 200 to be pre-assembled to thefolding frame assembly 100, such as before thestrength training system 10 is shipped to a customer. Such a configuration may decrease the assembly time of thestrength 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, thepulley machine 200 includes anupper pulley assembly 208 and alower pulley assembly 210. - The
upper pulley assembly 208 includes first, second, andthird pulleys coupler pulley assemblies lower pulley assembly 210 includes first, second, third, fourth fifth, andsixth pulleys coupler pulley assembly 230. - A first cable 228 is secured to the
weight rack 202. Movement of the first cable 228 results in movement of theweight rack 202. The first cable 228 extends from theweight rack 202 and over thefirst pulley 212. The first cable 228 then extends from thefirst pulley 212, over thesecond pulley 214 without engaging thesecond pulley 214, and into engagement with thethird pulley 216. The first cable 228 then extends downward and into engagement with the firstcoupler pulley assembly 218. - The
first coupler assembly 218 includes anupper pulley 232 and alower pulley 234 which are each coupled to aframe 236. In the illustrated example, theframe 236 includes opposing plates. Regardless of the configuration of theframe 236, the firstcoupler pulley assembly 218 allows theupper pulley 232 and thelower pulley 234 to rotate independently of each other, such as to allow independent rotation of cables or cable segments coupled to each of thepulleys pulleys - The first cable 228 is wrapped around the
