## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. provisional application Ser. No. 60/697,023, filed Jul. 6, 2005, which is incorporated herein in its entirety.


FIELD OF THE INVENTION
The invention relates to exercise machines and in particular to an exercise machine for simultaneously exercising the upper body and the lower body.
DESCRIPTION OF THE RELATED ART
Exercise machines are widely used to improve strength and cardio-vascular fitness, enhance balance, moderate the effects of aging, and generally promote health. Frequently, exercise machines are used for a single purpose, such as strengthening biceps or abdominal muscles, or for a limited number of inter-related purposes, such as improving heart and lung performance, or strengthening the upper body.
In order to exercise the entire body, it is necessary to use a variety of exercise machines or stations, or a large multi-station machine. While this may be feasible in a gymnasium or health club, it is impractical for most home installations because of usage space and storage limitations. Thus, an individual desiring a home-based exercise machine must limit his or her choices to a selected few devices focused on exercising only selected muscles, or must supplement home exercising with an out-of-home program at a health club or other facility.
SUMMARY OF THE INVENTION
An exercise apparatus for exercising a user's body comprises an upper exercise assembly, a lower exercise assembly, and a pair of step assemblies. The upper exercise assembly enables exercising of the user's upper body through alternating extension and retraction of the user's arms. The upper exercise assembly comprises an upright member coupled with an overhead member having an impact member suspended therefrom. The lower exercise assembly comprises an upright member coupled with a base member. The upright member of the lower exercise assembly can be coupled with the upright member of the upper exercise assembly. The pair of step assemblies is pivotally coupled with the lower exercise assembly for exercising the user's lower body through an alternating stepping motion. The user can repeatedly strike the impact member while performing the alternating stepping motion to simultaneously exercise the user's upper and lower body.

Other means of slidably attaching the clevis 56 to the base member 40 will be evident to a person of ordinary skill in the relevant art.
The lower exercise assembly 16 comprises a support post 80 supporting a left step assembly 82 and a right step assembly 84. The support post 80 terminates at an upper end in a hand rest 86 adapted for gripping by a user of the exercise apparatus 10, and at a lower end in an aperture for pivotable attachment of the support post 80 to the clevis 56. The support post 80 is also attached to the brace 42, preferably through a pivot connection. Alternatively, the brace 42 can be rigidly attached to the support post 80 to extend orthogonally thereto. The left step assembly 82 comprises a step rail 100 terminating at one end in a pedal 102. The right step assembly 84 comprises a step rail 104 terminating at one end in a pedal 106. The step rails 100, 104 are elongated, rigid structural members having a slot extending longitudinally along an upper surface thereof. As illustrated in FIG. 5C, the step rails 100, 104 can comprise a rectilinear tubular member comprising a pair of coplanar, parallel flanges 162, 164 in spaced-apart relationship to define a slot 166 therebetween. A lower wall of the step rails 100,104 comprises a bearing surface 160. The step rails 100, 104 are attached through a pivot connection 108 to a mounting member 120 fixedly attached orthogonally to the support post 80 at a lower portion thereof. A reinforcing gusset plate 122 can be used to strengthen the connection of the mounting member 120 to the support post 80. The step rails 100, 104 are provided with a clevis 124 rigidly attached to a clevis plate assembly 126 for pivotable attachment of resistance cylinders 88, 90 to the step rails 100, 104, respectively.
A resistance cylinder 88 is coupled to the left step assembly 82, and a resistance cylinder 90 is coupled to the right step assembly 84. The resistance cylinder 88, 90 comprises a piston rod 92, 94, respectively, and an internal piston to provide a dampening or resistance force to movement of the piston rod 92, 94 relative to the cylinder 88, 90. The piston rod 92, 94 is attached to the support post 80 through a pivot connection 96 to enable the resistance cylinder 88, 90 to pivot relative to the support post 80. The resistance cylinder 88, 90 can be adapted for selective adjustment of the resistance to movement of the piston rod 92, 94.
Referring now to FIGS. 5A and B, the pivot connection 96 preferably comprises a threaded post 140 extending orthogonally from the support post 80 adapted for slidable receipt of a washer 142, the piston rod 92, 94, and a washer 144, which are secured to the threaded post 140 by a lock nut 146.
Referring now to FIGS. 5A and C, the resistance cylinder 88, 90 terminates at a closed end in a sleeve adapted for receipt of a bushing 190 therethrough. A fastener 192, such as a threaded bolt, is adapted to extend through apertures 198, 200 in the clevis 124 and the bushing 190 to pivotally attach the resistance cylinder 88, 90 to the clevis 124. The fastener 192 is rotatably attached to the clevis with a lock washer 194 and a nut 196.
The clevis plate assembly 126 comprises a generally plate-like body having sufficient strength and rigidity for the purposes described herein, and adapted for fixed attachment to the clevis 124, such as by welding. As illustrated in FIG. 5C, the clevis plate assembly 126 comprises a top plate 170 to which the clevis 124 is attached. The top plate 170 is provided with a threaded aperture 186 extending therethrough for threadable receipt of a lock screw 184. The top plate 170 transitions laterally to a pair of parallel, depending side walls 172, 174 adapted for slidable registry with the slot 166. The side walls 172, 174 transition orthogonally to a pair of coplanar flanges 176, 178, which terminate in a pair of parallel, downwardly depending side walls 180, 182. The clevis plate assembly 126 can thus translate along the slot 166 and can be fixed in a preselected location along the step rail 100, 104 by threading the lock screw 184 against the bearing surface 160 to urge the flanges 176, 178 against the flanges 162, 164.
The support post 80 is also provided with a pulley 128 adapted to receive a cable 130 attached to the step rails 100, 104 through cable attachments 132, 134, such as eye bolts, for support of the step assemblies 82, 84. The cable 130 is looped over the pulley 128 and the step assemblies 82, 84 are suspended therefrom.
The upper exercise assembly 14 comprises a mounting plate 70 attached to an underside of the overhead member 34 and adapted for suspension of an impact member, such as a speed bag 72, through a universal connector 74 as is commonly known, such as a speed-bag hanger, an eye bolt and chain, and the like. The mounting plate 70 is a platen-like body comprised of a material such as wood, plastic, metal, fiber glass, and the like, having suitable strength and rigidity for the purposes described herein.
The height of the speed bag 72 can be adjusted by raising the upright member 32 relative to the insert portion 44 and using a fastener 62, such as a bolt or quick-release pin, to fix the upright member 32 at a selected height. The spacing of the lower exercise assembly 16 relative to the speed bag 72 can also be adjusted by adjusting the position of the brace 42 relative to the upright member 38 to rotate the support post 80 above the clevis 56, as indicated by arrow A of FIG. 3, using a fastener 48, such as a bolt or quick-release pin, to fix the brace 42 at a preselected position. The exercise apparatus 10 can also be disassembled and folded for storage by removing the upper frame 30 from the lower frame 36, disattaching the brace 42 from the upright member 38 and pivoting the brace 42 relative to the support post 80, and pivoting the base member 40 to an upright position adjacent the upright member 38, as indicated by arrow B of FIG. 3.
As illustrated in FIGS. 1 and 2, a user can perform a stepping exercise with the step assemblies 82, 84 to provide a cardiovascular workout while exercise the upper body by striking the speed bag 72. Alternatively, the stepping exercise can be performed while the user grips the hand rest 86. The stepping action will alternately pivot the left and right step assemblies 82, 84 about the pivot connection 108 while the cable 130 runs along the pulley 128 to provide movable support to the step assemblies 82, 84 and the user. The resistance cylinders 88, 90 provide adjustable resistance to the stepping action to control the cardiovascular effect of the exercise. The resistance delivered by the resistance cylinders 88, 90 can be adjusted by loosening the lock screw 184 and translating the clevis plate assembly 126 along the slot 166 to a desired location, and tightening the lock screw 184 to lock the clevis plate assembly 126 in position. Generally, resistance will be increased as the clevis plate assembly 126 is translated toward the pedal 102, 106.
The exercise apparatus 10 provides a full body workout and also works the body bilaterally, thereby improving core strength, balance, and coordination. In addition to a cardiovascular workout, the apparatus 10 strengthen the arms, shoulders, chest and back musculature through retraction/flexure and extension of the user's arms during use of the speed bag 72. Muscle endurance and strength are increased, along with strengthening of ligaments and tendons, and improved hand-eye coordination.
FIG. 6 illustrates a second embodiment of the invention which comprises many of the elements of the first embodiment described above, which are identified by the same identifiers. In the second embodiment, the lower exercise assembly 210 comprises a base frame 212 connected to the support post 80 and the base member 40 to provide additional strength and rigidity for the support post 80. The step rails 100, 104 are attached directly to the upright member 80 through a pivot connection 214. The pulley and cable are replaced by a pedal support assembly 216 comprising a crank arm 218 rotatably mounted to the support post 80. A pair of linkage members 220 is pivotally attached to the crank arm 218 and the step rails 100, 104 through pivot connections 222. The use of the lower exercise assembly 210 is identical to the use of the lower exercise assembly 16.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the forgoing disclosure and drawings without departing from the spirit of the invention which is defined in the appended claims.
