Description
BACKGROUND
1. Field of the Invention

The present invention relates generally to exercise machines, and more specifically to an exercise machine system that allows for incorporation of a plurality of attachments and a plurality of configurations, thereby allowing for the user to utilize one machine for a multitude of exercises.


2. Description of Related Art

Exercise machines are well known in the art and are effective means to provide various functions for the user to engage in one or more exercises. For example, FIG. 1 depicts a conventional exercise system 101 having a frame 103 configured to support an arm 105 with a handle 109, the arm 105 being pivotally connected 107 to the frame. During use, the user may add weight and/or resistance while utilizing arm 105.


One of the problems commonly associated with system 101 is limited use. For example, the user can only perform a limited number of exercises with the system. The user will then move on to another apparatus or machine to complete additional exercises.


Accordingly, although great strides have been made in the area of exercise machine systems, many shortcomings remain.

It is chosen and described to explain the principles of the invention and its application and practical use to enable others skilled in the art to follow its teachings.


Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views, FIG. 2 depicts a front perspective view of an exercise machine system 201 in accordance with a preferred embodiment of the present application. It will be appreciated that system 201 overcomes one or more of the above-listed problems commonly associated with conventional exercise systems. It should also be appreciated that system 201 may vary as functional, manufacturing, or aesthetical considerations require.


In the contemplated embodiment, the exercise machine system 201 includes a plurality of lever arms 203 coupled to a plurality of vertical posts 205 via a carriage 207. It should be appreciated that the vertical posts 205 may be, at least in part, from a Smith machine, a functional training rig, or the like. In addition, the vertical posts 205 may include a plurality of adjustment holes 209 for receiving different accessories or attachments (e.g., the carriage 207). Further, the vertical posts 205 may include foot plates 211 at lower ends thereof for anchoring the vertical posts 205 to the floor.


The carriage 207 is configured to adjust up and down along the vertical posts 205 via the plurality of adjustment holes 209. The carriage 207 includes one or more handles 213 for user manipulation. The carriage 207 also includes a first brace 215 creating a channel 217 to engage with the one or more vertical posts 205. The carriage 207 also includes a pivoting system 219 extending from the first brace 215. The pivoting system 219 includes a side-to-side pivoting connection 221 attached to a second brace 223. The side-to-side pivoting connection 221 allows for the second brace 223 to pivot about a horizontal axis, thereby allowing for horizontal movement of the lever arm 203. The pivoting system 219 also includes a rotating connection 225 attached to the second brace 223. The rotating connection 225 allows for the lever arm 203 to pivot from side-to-side.

The lever arm 203 also includes a plurality of adjustment holes 233 for additional adjustability of the grip system 227.


The exercise machine system 201 further includes a cable system 235 which provides for attachment and manipulation of various devices that can be used for various exercises. In addition, one or more protrusions 237 extend from the lever arm 203 for such engagement as well.


It should be appreciated that one of the unique features believed characteristic of the present application is the carriage 207, which provides for various manipulation of the lever arms 203, thereby providing for various exercise configurations and uses. For example, the carriage 207 allows for the lever arms 203 to be adjusted vertically, from side-to-side, and in a pivoting direction.


It should also be appreciated that because of the various adjustments that can be performed via the carriage 207, the exercise machine system 201 is suitable for adding attachment devices that can provide a number of exercises. The use of the attachments can go on to perform all hammer strength or cybex leverage type movements such as decline chest press, chest press, incline chest press, military press, all variations of lat pulling and rowing movements, dips, and more. A leg press foot plate attachment allows for the lever arms to dock into the versa-form to become a 45-degree leg press unlike anyone has ever been able to do. The foot plate attachment also can swivel to allow arms to become a vertical leg press or be paired with the leverage arm and then do all leverage leg press moves as well taking place of all of those machines. The shoulder full back pad attachment allows arms to become a pendulum squat machine by using the versa forms angles foot plate. That same attachment used in other ways can allow arms to become a hack squat, hip sled, V squat. A shoulder pad attachment allows arms to become a squat pro machine. A tri axis single handle attachment can be used to perform many of the above-mentioned moves and more by allowing ultimate adjustability for the handle to confirm to almost any lever, leverage, or smith machine movement. The counterbalance cable attachment allows the leverage arm and its carriage to attach to the lever arms cable and then become a counterbalance to perform all counter balance exercises like assisted pull-ups or dips. Cushion pads attachment can be used to make arms into leg extension, leg curl, low back extension, seated Ab machine and more. Curved bar attachment can make arms into a preacher curl, overhead tricep extension, and more. A Smith straight bar allows arms to use carriage system to be used as a smith machine Single handles can be used to perform unilateral smith type functions as well as unilateral lever and leverage moves. This design can also be modified to use stack weight and cable it allows the same movements and machine functions but no plate weights needed.
