DETAILED DESCRIPTION

Referring first to FIG. 1, an exercise apparatus is generally identified by the reference numeral 100. The exercise apparatus 100 may be of known construction and may include a base 110 supporting an endless treadmill belt 112 or slats secured to an endless chain and the like typically powered by an electric motor. A user may walk, jog and/or run on the treadmill belt 112. Upright stanchions 114 may extend generally upward from a front end of the base 110. The stanchions 114 may be spaced apart from one another. A cross bar connected between the stanchions 114 proximate an upper end thereof may support an interactive display 116 providing a user interface configured to perform a variety of functions, including displaying information to the user, such as available exercise parameters and/or programs and the like. Frame extensions 118 may extend generally horizontally from the upper ends of the stanchions 114 toward the rear end of the base 110. The frame extensions 118 may be parallel and define a space therebetween approximately equal to the width of the treadmill belt 112. The frame extensions 118 may be integrally formed with the stanchions 114 or fixedly connected thereto by welding or bolt connectors or other suitable means.

A handlebar assembly 120 may be pivotally connected to the frame extensions 118 at a connector joint 121 such that handlebar assembly 120 may be folded into a stored and parked position, more fully described in U.S. Pat. Nos. 9,474,928 and 9,907,994, which patents are herein incorporated by reference in their entirety. The handlebar assembly 120 may be adjustably rotated about a pivot shaft 122 to move the handlebar assembly 120 fore or aft to orient the handlebar assembly 120 to a user's preferred orientation.

The handlebar assembly 120 of the exercise apparatus 100 may include generally vertically extending elongated lower handlebar members 124 fixedly secured to respective frame extensions 118 at connector joints 121. Generally, vertically extending elongated upper handlebar members 126 may be connected to the lower handlebar members 124 in end to end relationship. Load sensors 128, for example but without limitation, load cells or strain sensors, may be interposed between the upper handlebar members 126 and the lower handlebar members 124. The load sensor 128 may be captured between an upper flange 130 secured proximate the lower end of the upper handlebar member 126. A lower flange 132 may be secured proximate the upper end of the lower handlebar member 124 in facing relationship to the upper flange 130. The flanges 130, 132 may be integrally formed with the handlebar members 124, 126 or fixedly secured thereto by welding or other suitable means.

A handlebar 134 may be movably supported between the upper handlebar members 126. The handlebar 134 extends transversely between the upper handlebar members 126 terminating at journals 136 at the distal ends thereof which slide over the upper handlebar members 126. Knobs 138 connected to the journals 136 may be loosened to slide the handlebar up or down relative to the upper handlebar member 126 and thereafter tightened to a different height to accommodate different users.

During use of the exercise apparatus 100, as a user exerts a downward force at handlebar 134, absolute arm force and/or force as a percentage of user body weight may be digitally or graphically indicated at the console 116. In the example illustrated in FIG. 1, the console 116 displays average downward arm force in bar graph 117, and average downward leg force in bar graph 119 subjected to the treadmill belt 112 or treadmill deck. In the example illustrated in FIG. 8, a user weighing 175 pounds, exerting a downward force of 72 pounds at the handlebar 134, subjects the treadmill belt 112 to 103 pounds of downward force. Furthermore, in the example illustrated in FIG. 8, bar graphs 117 and 119 may illustrate the upper body experiencing 41% of the user's body weight, while the user's legs are experiencing 59% of the user's body weight. The treadmill frame may optionally be supported with a plurality of strain sensors 121, which after tare is accounted for, measure the total body weight of the user. With this optional arrangement the user's body weight does not need to be entered manually.

Although manual means are shown to adjust the height of the handlebar 134, remote control electric and/or mechanical actuators may be utilized such as but not limited to solenoids, servo motors, and/or hydraulic and/or pneumatic components in order to adjust the handlebar 134 height. Additionally, the handlebar 134 may be secured to the upper handlebar member 126 in a movable manner and biased upward with a spring, pneumatic, hydraulic, or similar functioning component such that a downward force at the handlebar 134 causes downward displacement of the handlebar 134 (see FIG. 9). Absolute force (with load cell 128) and/or percentage of user body weight transferred from the user's lower body to the user's upper body may continue to be measured whether or not downward (movable) displacement of the handlebar 134 occurs.

Referring now to FIG. 2, a second embodiment of an exercise apparatus is generally identified by the reference number 200. The exercise apparatus 200 may be of known construction and may include a base 210 supporting an endless treadmill belt 212 and the like typically powered by an electric motor. A user may walk, jog and/or run on the treadmill belt 212. Upright stanchions 214 may extend generally upward from a front end of the base 210. The stanchions 214 may be spaced apart from one another. A cross bar connected between the stanchions 214 may support an interactive display 216 providing a user an interface configured to perform a variety of functions, including displaying information to the user, such as available exercise parameters and/or programs and the like. Frame extensions 218 may extend generally horizontally from the stanchions 214 toward the rear end of the base 210. The frame extensions 218 may be parallel and define a space therebetween approximately equal to the width of the treadmill base 210. The frame extensions 218 may be integrally formed with the stanchions 214 or fixedly connected thereto by welding or bolt connectors or other suitable means.

The stanchions 214 extend generally upward from the base 210 with a slight rearward arc terminating at collars 230. A handlebar 234 may include a generally horizontal portion and downwardly extending leg members 236 forming an inverted U-shaped profile. The leg members 236 extend through the collars 230. Knobs 238 connected to the collars 230 may be loosened to slide the handlebar 234 up or down relative to the stanchions 214 and thereafter tightened to a different height above the treadmill 212 to accommodate different users.

A load sensor 240, such as but without limitation, a foil strain gage, may be fixed to the stanchions 214. A downward force applied by the user at the handlebar 234 may be digitally or graphically indicated at the console 216, more fully described above in reference to exercise apparatus 100.
