DETAILED DESCRIPTION

[0022] In the following description, for purposes of explanation and not limitation, specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods and devices are omitted so as to not obscure the description of the present invention with unnecessary detail.

[0023] Referring first to FIG. 1, exercise apparatus 10 has a frame comprising a central upright 12, top member 14, base member 16 and legs 18 and 20. Footplate 22 is attached between legs 18 and 20. A lat bar assembly 24 is attached to top member 14. Selector tubes 26, 28 are attached between lat bar assembly 24 and leg 18 and between lat bar assembly 24 and leg 20, respectively.

[0024] Backrest cushion 30 is attached to central upright 12, as are right handlebar assembly 32 and left handlebar assembly 34. Arm cushions 36, 38 are attached to handlebar assemblies 32, 34, respectively.

[0025] Carriage assembly 40 is slidably mounted on selector tube 26 and may be positioned at any desired height by means of pull pin 41 engaging with one of a plurality of holes (not shown) in the selector tube. Carriage assembly 42 is similarly slidably mounted on selector tube 28. A variety of weight resistance exercises may be performed using handles 44 and 46 that are operatively associated with carriage assemblies 40 and 42, respectively, as more fully described below. Exercise resistance is furnished by a selectorized weight stack 48. A shroud 49 may partially enclose weight stack 48.

[0026] Referring also to FIG. 2, the cable and pulley arrangement of apparatus 10 will be described. Looking to the right side of the figure, pulleys 52R and 54R are rotatably mounted on carriage assembly 40. The two ends of cable 50R are reeved around these two pulleys and are coupled to handle 44, as will be explained below. Continuing up from pulley 52R, cable 50R is reeved around a fixed high pulley 56R and then around another high fixed pulley 58R. Cable 50R then travels downwardly around floating pulley 60R and then upwardly around high fixed pulley 62R. Cable 50R continues down around low fixed pulley 64R and then around low fixed pulley 66R. From there, cable 50R travels upwardly and is reeved around pulley 54R. The cable and pulley arrangement on the left side of the apparatus is a mirror image of that just described.

[0027] Cable 68 is attached to floating pulley 60R and travels down and around low fixed pulley 70R. Cable 68 then travels upwardly and around high fixed pulley 72R and then back down and around pulley 74 on the top of weight stack 48. Again, the left side of the apparatus is a mirror image with cable 68 travelling upwardly from pulley 74, around high fixed pulley 72L, then downwardly and around low fixed pulley 70L, and then upwardly to where it is attached to floating pulley 60L.

[0028] From FIG. 2, it can be seen that pulling on either end of cable 50R, or on either end of cable 50L, will be resisted by one-fourth of the weight of weight stack 48. Pulling on both ends of cable 50R simultaneously, or on both ends of cable 50L simultaneously, will be resisted by one-half of the weight of weight stack 48.

[0029] Details of right side carriage assembly 40 are shown in FIG. 3. It will be understood that left side carriage assembly 42 is a mirror image of assembly 40. A first end 76 of cable 50R exits between a first upper pulley 52R on carriage assembly 40 and a first lower pulley 78R. Similarly, a second end 80 of cable 50R exits between a second upper pulley 82R and a second lower pulley 54R. The first end 76 of cable 50R is inserted through ball stop 84 and is secured to bracket 86 by bolt 88. The second end 80 of cable 50R has a small ball fitting 90 that may be inserted into slot 92 of bracket 86. If the second end 80 is not secured to the bracket 86, it is retained between pulleys 82R and 54R by ball stop 94. Handle 44 (shown in FIG. 1) is coupled to a bracket 86. As previously explained, the first end 76 of cable 50R is secured to bracket 86, so that pulling on the handle will draw out cable 50R from between pulleys 52R and 78R. Pulling in this manner will be resisted by one-quarter of the weight of weight stack 48. If ball 90 is inserted into slot 92, thereby securing the second end 80 of cable 50R to bracket 86, pulling on handle 11 will be resisted by one-half of the weight of weight stack 48. When using one cable end ( resistance), the user gets twice the amount of cable travel as when using both cable ends ( resistance). Functional exercises that simulate body movements of sports activities movements require more travel, whereas traditional training exercises such as lat pull downs require more resistance.

[0030] In a variation of the above-described embodiment, the carriage assemblies could each have two pulleys instead of four. In this case, it would be preferred that the two pulleys would be slightly offset from each other axially so that the cable from either pulley would clear the other pulley during use. In this variation, the upper end of the cable would be reeved around the upper pulley and the lower end of the cable would be reeved around the lower pulley. For example, this could be accomplished by modifying carriage assembly 40 shown in FIG. 3 to omit pulleys 78R and 82R. Suitable cable guides or brackets could then be provided to interface with ball sops 84 and 94 to prevent the cable ends from slipping past pulleys 52R and 54R. As in the previously described embodiment, each cable end could be used independently or together to achieve a desired resistance ratio.

[0031] Another embodiment of the present invention is illustrated in FIGS. 4-7. A first carriage assembly 102 has a pair of pulleys 104, 106 rotatably mounted thereon. First cable end 108 exits between pulleys 104 and 106 and may be coupled to a handle 110 or a bar (not shown) for performing various exercises. The first carriage assembly 102 is adjustable up and down a slider shaft 112 and is lockable at various positions along the slider shaft. A second carriage assembly 114 is disposed on slider shaft 112 above the first carriage assembly 102. The second carriage assembly 114 has an exercise press bar 116 associated with it. A second cable end 118 is releasably attached to eye 120 on the second carriage assembly 114. The second carriage assembly slides up and down the slider shaft and may be locked in a stowed position at the top of the slider shaft when not in use as shown in FIG. 5. It should be understood that an exercise apparatus incorporating this embodiment of the invention will preferably have two of the previously described arrangementsone each for the left and right sides of the body.

[0032] When using the press bar 116 associated with the second carriage assembly, the second carriage assembly 114 is lowered from its stowed position at the top of the slider shaft and rested on top of the first carriage assembly 102. Attaching the first cable end to eye 122 on the second carriage assembly 114 with the second cable end attached to eye 124 on the first carriage assembly 102 as shown in FIG. 6 provides a first exercise resistance to the press bar. Attaching the second cable end to eye 120 on the second carriage assembly as shown in FIG. 7 provides a second, greater resistance to the press bar.

[0033] The configuration shown in FIGS. 4-7 could be reversed with the second carriage assembly located below the first carriage assembly, in which case an exercise bar attached to the second carriage assembly could be used as a pull bar. In this case, the stowed position for the second carriage assembly would be at the bottom of the slider shaft.

[0034] FIG. 8 illustrates an exercise apparatus 200 in accordance with another embodiment of the invention. Apparatus 200 is a functional trainer with multiple pull points for performing a wide variety of exercises. Two wide, adjustable pull points 201L and 201R, shown here with D-handles, are provided on carriages 202L and 202R, respectively. The pull points are coupled to respective selectable weight stacks 204L and 204R by paired cable and pulley systems similar to those used on apparatus 10 described above. The carriages are vertically slidable on vertical members 212L and 212R, respectively, and include a sleeve that encircles guide rods 206L and 206R, respectively. The carriages may be locked at a desired height by means of respective release levers 208, which couple to pins (not shown) that engage holes 210 in vertical members 212L and 212R.

[0035] When carriages 202L and 202R are positioned at a mid height, pull points 201L and 201R may be used to perform such exercises as standing chest presses, incline presses, decline presses, flys and close grip presses. When the carriages are positioned low, near the bottom of guide rods 206L and 206R, pull points 201L and 201R can be used to perform exercises such as shoulder presses, squats, bicep curl, lateral raise and front delt. When the carriages are positioned high on the guide rods, these pull points can be used to perform a wide lat pull down.

[0036] Apparatus 200 includes a Smith bar 220. As will be explained more fully below, the Smith bar can be coupled to the weight stacks 204L and 204R to perform exercises commonly performed on conventional Smith machines, such as squats, dead lifts, bench press, incline press, shoulder press, decline press and upright row. Coupling the selectable weight stacks to the Smith bar eliminates the need to use free weights, as is the case with conventional Smith machines.

[0037] When not in use, the Smith bar 220 is stowed on overhead pulley support members 222L and 222R by means of secondary brackets 224L and 224R, each of which functions as a catch to engage respective pins 226 on the pulley support members as seen in FIG. 9. An additional safety lock can be swiveled under the Smith bar to prevent falling if the Smith bar is accidentally rotated. The Smith bar 220 rotates axially just like a conventional Smith bar and may be removed from its stowed position by rotating the bar to disengage the secondary brackets from pins 226 as seen in FIG. 10.

[0038] To perform exercises with the Smith bar, carriages 202L and 202R are first brought to a mid position at equal heights on guide rods 206L and 206R. The Smith bar is then removed from its stowed position and brought down to the carriages. Cable ends 228L and 228R, which are normally hooked onto the respective carriages as seen in FIG. 11, are unhooked from the carriages and slid over to hook onto the Smith bar end brackets 225L and 225R as seen in FIG. 12, thereby coupling the Smith bar to the weight stacks. Secondary brackets 224L and 224R attached to the Smith bar function as release actuators to engage the carriage release levers 208 so that rotating the bar allows the carriages to move up and down on the guide rods using the Smith bar to move them. This release, move and lock feature allows the carriages to work as a safety when performing exercises such as squats. The bar and carriages are first lowered to a desired safety position. Then the bar is rotated to release the levers 208 and lock the carriages in place. The selected exercise weights remain attached to the bar by virtue of the cable ends 228L and 228R being hooked onto the bar end brackets 225L and 225R. When done exercising, the bar is brought back down to pick up the carriages. The exerciser then stands up and allows the carriages to lock into place. The Smith bar may then be left with the carriages or brought to the top and stored on pins 226. An additional safety lock may be engaged with the Smith bar when stored.

[0039] As with the exercise apparatuses described above in connection with FIGS. 1-7, apparatus 200 incorporates a weight multiplier for doubling the exercise resistance applied to Smith bar 220. To engage the weight multiplier, the cable ends 230L and 230R of pull points 201L and 201R are attached to bar end brackets 225L and 225R, respectively, as seen in FIG. 13.

[0040] It will be recognized that the above-described invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the disclosure. Thus, it is understood that the invention is not to be limited by the foregoing illustrative details, but rather is to be defined by the appended claims.
