DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0034] Although the following detailed description contains specific details for the purposes of illustration, those of ordinary skill in the art will appreciate that variations and alterations to the following details are within the scope of the invention. Accordingly, the exemplary embodiments of the invention described below are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention.

[0035] An exercise apparatus is provided for exercising one or more muscle groups of a user's body. Apparatus may be dedicated to exercising a specific muscle or group of muscles as is the case with a wide variety of single station exercise machines that are now available. Alternatively, apparatus may be a multi-station exercise machine having a number of exercise stations, each of which is configured for exercising a particular muscle group. The exercise apparatus has a frame having a base and a mast attached to the base. A pivotable platform or bench on which the user can be positioned is operatively connected to the base and, in the quiescent state of the apparatus, parallel to the base. A handlebar unit, preferably comprising two grips, is connected to the mast, the handlebar unit having at least one sensor operable by the individual user. A drive element such as a hydraulic, pneumatic, or linear motor system, is operatively connected to the mast for producing motion to the handlebar unit.

[0036] Referring now to FIG. 1, there is shown a side schematic view of the exercise apparatus 10 in accordance with the present invention.

[0037] A substantially planar, rigid base 12 is fabricated from steel or other metal in the preferred embodiment. Leveling knobs 14 with screw adjustment screws are provided at the lower surface of base 12 in a manner well known to those skilled in the art.

[0038] Connected to base 12 is a rigid mast 16 having a hollow structural section (HSS) substantially perpendicular thereto. The hollow portion of mast 16 allows for routing electrical wires therethrough, as described hereinbelow.

[0039] A substantially planar, rigid platform or bench 18 is supported by a support 19, all of which are fabricated from steel or other metal in the preferred embodiment. Bench 18 is pivotably mounted to support 19 at pivot point 19. In the quiescent state of apparatus 10, bench 18 is disposed parallel to base 12, but can be adjusted relative to base 12 by the user, not shown.

[0040] A handlebar unit, preferably comprising two grips 20, is operatively and slidably connected to mast 16, each grip of the handlebar unit 20 having a dead man's pressure switch 22 operable by the user. Optionally, a third degree of readiness can allow a user to push up on handlebar unit 20, which would activate pressure switch 22. As a safety feature, pressure switch 22 requires the user to push upward a minimum distance before the conditions are met to start the handlebar unit 20 downward. If a predetermined minimum resistance is not maintained, apparatus 10 returns to its start position.

[0041] A drive element 24, such as a hydraulic, pneumatic, or mechanical (e.g., linear motor) system, is operatively connected to mast 16 for producing resistance to handlebar unit 20. In the preferred embodiment, drive element 24 is a hydraulic system operated by an electric motor, not shown. A desired level of resistance can be selected by the user by controlling the drive element 24. A display panel, not shown, includes a touch screen in the preferred embodiment, mounted proximate apparatus 10 so the user or another person can select limit distances and negative mode forces.

[0042] An upper limit switch 26 and a lower limit switch 28 are provided at the extreme upper and lower ends of mast 16, respectively, to limit sliding motion of handlebar unit 20.

[0043] In operation, the user positions himself on bench 18, reaches upwardly and grasps the grips of handlebar unit 20, each side with one hand. The user pulls handlebar unit 20 downwardly to exercise the muscles in his arms and chest. It should be understood that, while a weight lifting apparatus is herein described, apparatus 10 can be reconfigured and/or modified to allow a user to isolate and exercise various parts of the human body, such as legs, back, etc.

[0044] Exercise apparatus 10 operates on the principle of negative resistance technology, so when the user releases one or two handlebar pressure switches 22, handlebar unit 20 returns to an initial position relative to mast 16, and the user can rest, start again or depart from apparatus 10.

[0045] The safety of the user is paramount with this equipment, especially since heavy weights and their momentum are involved during operation of the apparatus 10. Accordingly, pressure switch 22 associated with each grip of handlebar unit 20 requires the user to push upward a minimum distance before the conditions are met to start the handlebar unit 20 downward. If a predetermined minimum resistance is not maintained, apparatus 10 returns to its start position.

[0046] Referring now to FIG. 2, there is shown a block diagram of the components of the bench 10 and control system therefor.

[0047] Referring now to FIG. 3, there is shown a photograph illustrating another embodiment of the invention. In this bench press, handlebar 20 starts at top of stroke, which is adjustable. When a user indicates readiness, handlebar 20 is driven downwardly, which downward motion continues until the user ceases demonstrating readiness or handlebar 20 reaches end of travel. The user sets maximum downforce, and handlebar motion slows or stops if resistance is near or reaches the predetermined set point.

[0048] Referring now to FIG. 4, there is shown a photograph of a press illustrating yet another embodiment of the invention. This press can also become a Lat Pull if the hydraulic action is changed to pull up. The Lat Pull will require leg restraints as force can exceed body weight. For squat exercises, handlebar 20 drives downwardly when the user is ready, which downward motion continues until the user ceases demonstrating readiness or handlebar 20 reaches end of travel. The user sets maximum downforce, and handlebar motion slows or stops if resistance is near or reaches the predetermined set point.

[0049] Referring now to FIG. 5, there is shown a photograph of a press illustrating yet another embodiment of the invention in which a user can perform leg exercises. When a user indicates readiness, the machine drives a foot plate 26 downwardly, which downward motion continues until the user ceases demonstrating readiness or foot pedal 26 reaches end of travel. The user sets maximum downforce, and foot plate motion slows or stops if resistance is near or reaches the predetermined set point.

[0050] Referring now to FIG. 6, there is shown a photograph of a press and user illustrating yet another embodiment of the invention in which a user can perform standing curls. A T-bar 24 is free to pivot so a user's arm can travel through an arc. When the user indicates readiness, the machine drives T-bar 24 downwardly, which downward motion continues until the user ceases demonstrating readiness or T-bar 24 reaches end of travel. Once again, the user sets maximum downforce, and T-bar motion slows or stops if resistance is near or reaches the predetermined set point.

[0051] Referring now to FIGS. 7-13, there are shown schematic illustrations of the press in accordance with the invention, as well as positions of users in respective workout positions.
