Description
- This application is related to U.S. Provisional Patent Application No. 60/597,554 filed Dec. 8, 2005 from which priority is claimed, and is hereby incorporated by reference.
- Not Applicable.
- The present invention relates generally to a fitness apparatus, and more particularly, to a tensioning system for a fitness apparatus.
- Many fitness apparatus use various arrangements of cable and pulley systems to provide weight training exercises. Generally, a cable is engaged at one end with a resistance member, such as a weight stack, and engaged with a user interface, such as a bar, at the other end. The length of the cable is engaged with a set of pulleys, which allow the cable to efficiently transmit resistance from the resistance member to the user interface. In operation, the user engages the user interface to repeatedly raise and lower the resistance member by way of the cable and pulley system.
- It is desirable that the cable and pulley system move smoothly and provide a substantially constant resistance to the user interface over the full range of motion. However, frequent use of fitness apparatus and the high forces placed of the cable causes the cable to stretch, which adversely affects the performance of the fitness apparatus by introducing slack into the cable and pulley system. As a result, the stretched cable will not work effectively over the full range of motion of the interface. The user may have to engage and move the interface a distance before the cable and pulley system begin transmitting the resistance to the interface, sometimes referred to as a “dead-spot”. If allowed to stretch enough, the cable can become loose enough that it disengages from the pulleys. Routine maintenance must be performed on such fitness apparatus to reduce slack in the cable and pulley system as the cable continues to stretch.
- Therefore, what is needed is a device that maintains tension on the cable and pulley system to compensate for cable stretch.

- As shown in
FIGS. 1-3 , an embodiment of the present invention, generally referred to as afitness apparatus 10, is shown having atensioning system 12. Thefitness apparatus 10 includes aframe 14 for supporting aresistance member 16, such as weights, and a cable andpulley system 18 that connects between theresistance member 16 and first andsecond interface members resistance member 16, such as by selecting the desired weight (ie. 20lb, 40 lb, etc.), and engage either thefirst interface member 22 orsecond interface members 24 to perform various fitness exercises. For various reasons, there may be some slack or looseness present in the cable andpulley system 18, such as stretching in thecables tensioning system 12 mounts to theframe 14 and engages the cable andpulley system 18 to apply a biasing force to maintain proper tension and eliminate any slack in the cable and pulley system 18 (FIG. 3 ). - The
frame 14 includes abase 30 with afirst leg 32 extending upwardly from a rear portion of thebase 30 in a generally vertical orientation and asecond leg 34 extending upwardly from about a middle portion of thebase 30 in a generally vertical orientation (FIG. 1 ). An arcuately-shaped upper portion of thesecond leg 34 extends generally rearward to connect to an upper portion of thefirst leg 32 for additional support. Aseating arm 36 extends generally forward from a lower portion of thesecond leg 34 in a generally horizontal orientation to support aseat 38. Theseating arm 36 should be positioned at an appropriate height for seating, preferably about one third of the height of thesecond leg 34. Abackrest 39 is attached to thesecond leg 34 at a location above and corresponding to theseat 38. - The
resistance member 16 operatively connects to theframe 14 with a bushing 40 that slidably couples with thefirst leg 32. In this way, the bushing 40 andresistance member 16 can slide up and down along thefirst leg 32. However, any other appropriate means for connecting theresistance member 16 to theframe 14 can be used, such as bearings.Support posts 42 extend outwardly from the bushing 40, which are capable of receiving and supporting theresistance member 16. Theresistance member 16, shown as weights, can be added or removed incrementally so that the user can select a desired resistance. - The
first interface member 22 is a lever arm having aproximate end 44 that is pivotally attached to adistal end 46 of theseating arm 36. The cable andpulley system 18 attaches to adistal end 48 of thefirst interface member 22, thereby operatively connecting theresistance member 16 to thefirst interface member 22. Thus, thefirst interface member 22 can be engaged by the user to perform leg exercises by pivoting thefirst interface member 22 upwardly and downwardly with his or her legs, thereby raising and lowering theresistance member 16 via the cable andpulley system 18. - A
cross member 50 attaches to the upper portion of thesecond leg 34 and is positioned in a generally horizontal position to support thesecond interface members 24, shown inFIGS. 1-2 as handle straps, and the cable andpulley system 18. The cable andpulley system 18 attaches to eachsecond interface member 24, thereby operatively connecting theresistance member 16 to thesecond interface members 24. Thus, thesecond interface members 24 can be engaged by the user to perform various exercises, such as arm exercises, by pulling and releasing thesecond interface members 24, thereby raising and lowering theresistance member 14 via the cable andpulley system 18. While the first andsecond interface members - The cable and
pulley system 18 includes various guide pulleys positioned to guide afirst cable 26 andsecond cable 28 during operation of the fitness apparatus 10 (FIG. 1 ). Twoupper pulleys 52 are positioned respectively at the upper portion of thefirst leg 32 and the upper portion of thesecond leg 34. Fourlower pulleys 54 are positioned along thebase 30. Aguide pulley 56 is positioned at each end of the cross member 50 (FIG. 2 ), such as with a hook. A double-floatingpulley 58 operatively connects thefirst cable 26 to the second cable 28 (FIG. 1 ). The first cable ends 60 attach respectively to theresistance member 16 and thefirst interface member 22, such as with a snap-hook, with the length of thefirst cable 26 engaging theupper pulleys 52 andlower pulleys 54. The second cable ends 62 attach to thesecond interface members 24, such as with a snap-hook, with the length of thesecond cable 28 engaging theguide pulleys 56 and a double floatingpulley 58. Cable stops 64 attach to thesecond cable 28 proximate to the second cable ends 62 to prevent thesecond cable ends 62 from being drawn through and disengaging from theguide pulleys 56. - The double floating
pulley 58 includes atop pulley 66 and abottom pulley 68 connected by abracket 70 and positioned generally perpendicular to each other along a longitudinal axis (FIG. 3 ). Thebottom pulley 68 engages thefirst cable 26 and thetop pulley 66 engages thesecond cable 28, so that the double floatingpulley 58 is suspended therebetween. In this way, thesecond cable 28 is operatively connected and to theresistance member 16 via thefirst cable 26. - The
tensioning system 12 includes a pair of floatingpulleys 72 operatively engaged with thesecond cable 28, and connected to theframe 14 with biasingmembers 74, such as a helical tension spring, and a bracket 76 (FIG. 3 ). The biasingmembers 74 are shown inFIG. 3 as helical tension springs, but can be any other type of biasing member, such as, a compression spring, a torsion spring, a volute spring, a conical spring, a gas spring, a spiral spring, a wire form, an elastic band, and the like. In addition, various biasingmembers 74 can be used to increase or decrease the biasing force. Each floatingpulley 72 is pivotally mounted, such as with afastener 78, within a generally C-shapedhousing 80. Thehousing 80 includes atab 82 with ahole 84 for connecting to the biasingmember 74, such as with apin 86. When assembled, thesecond cable 28 is disposed between thepulley 72 and thehousing 80. In this way, thehousing 80 helps maintain engagement of thesecond cable 28 with thepulley 72 by shielding the area of engagement from interference by foreign objects. - The
tensioning system 12 maintains tension on thesecond cable 28 by applying a generally perpendicular force to thesecond cable 28 along the longitudinal axis of the biasingmember 74. This forces thesecond cable 28 away from its natural travel path (shown as the dotted line inFIG. 3 ) between the double floatingpulley 58 and the guide pulleys 56, which effectively makes the travel path of thesecond cable 28 longer and removes slack. The tension maintained on thesecond cable 28 is continuous during both operation and non-operation of theapparatus 10. In this way, thetensioning system 12 automatically adjusts the travel path of thesecond cable 28 as it stretches. Therefore, no manual adjustment of theapparatus 10 is needed to compensate for the stretching of thesecond cable 28. -
