Exercise apparatus such as a treadmill
An improved exercise apparatus, such as a treadmill, which includes a pressure receiver, such as a padded plate or bar, which a treadmill user applies pressure against while using the treadmill. A pressure sensor and a display may be included which measures and indicates the amount of pressure applied, and/or the amount of deviation from a desired amount of pressure. Having the user apply pressure to the pressure receiver, additional muscle groups in the user's body are exercised. The treadmill belt may be either motorized or non-motorized, with the ability to allow the user to go either forward or backward thereon while still applying pressure to the pressure receiver. The speed of the belt, the resistance applied to the belt (if unmotorized), and the elevation angle of the belt may be adjusted to suit the user.
This invention relates to exercise equipment generally, and, more specifically, to treadmill exercise equipment.
BACKGROUND OF THE INVENTIONTreadmills are the most popular method of exercise equipment used at home and in gyms, etc. A user of the treadmill adjusts the speed and, possibly, the direction of a belt on the treadmill to suit the user's desire for exertion. In addition, the user can adjust the inclination of the treadmill to further control the amount of exertion. However, treadmills generally provide exercise to only limited set of muscle groups located mostly in the user's legs.
One approach to increase the utility of the treadmill is adding moveable arms along the side of the treadmill to simulate cross-country skiing. The amount of force needed to deflect the arms and the length of the arms are adjustable to the needs of the user. This adaptation to the basic treadmill adds the ability to exercise the arm and shoulder muscles at the same time as the leg muscles.
Another approach, such as a treadmill named The Force and manufactured by Woodway of Waukesha, Wis., has a user wearing a harness (tether) strapped across the user's chest, the user having the ability to adjust the resistance of the treadmill's belt. No provision is made to measure the force exerted by the user on the harness. Because this arrangement restricts the selection of muscle groups in the user's torso for exercise and the amount of exercise applied the user's torso muscles is not measured, the user's torso muscles are not exercised properly if at all.
To date, there has not been a treadmill that allows for the selective exercise of muscles in a user's torso.
Therefore, it is desirable to provide for a treadmill that allows a user to select a muscle group in the user's lower back, abdominal, and gluteal regions. Further, it is desirable that a user be able to select the amount of exercise/exertion applied to the selected muscle groups.
SUMMARY OF THE INVENTIONThese and other objects of the invention may be obtained generally with an exercise apparatus, such as a treadmill. In one exemplary embodiment, the treadmill has a belt for a user to tread thereon and a pressure-measuring device attached to the treadmill. The measuring device is adapted to receive pressure from a user while using the treadmill.
In an additional embodiment of the invention, a method of exercising includes treading on a belt on a treadmill while exerting pressure on a pressure receiver, and measuring the pressure exerted.
The invention may be understood generally from the following figures, none of which is to scale:
An illustrative embodiment of the invention is shown in
The speed/direction of belt 12 and the angle of the base 111 are typically controlled by a user though a control panel (not shown) located in pedestal 13. Pedestal 13 also provides support for the user as he/she uses the treadmill 10. Levers 15 may also be provided to give additional exercise to the user as he/she uses the treadmill 10.
In the exemplary embodiment of the invention and described in more detail below in conjunction with
For purposes of this description, the terms “force” and “pressure” are used interchangeably.
While not shown, the receiver 18 may be mounted on something other than the treadmill 10, such as a wall (not shown) or a framework (not shown) which is in turn attached to a floor, wall, or to the treadmill 10.
To assist the user in his or her exercise, a pressure sensor (not shown) is added to the receiver 18. As will be explained in more detail below, the amount of asserted pressure is measured and may be displayed to the user so that the user can determine the amount of pressure applied or deviation in the amount of pressure from a predetermined amount of pressure. With this arrangement and the user applying an approximately constant pressure, muscles in the exemplary abdominal, back, and gluteal regions may then be exercised.
Turning to
It is understood that a treadmill 10 with a non-motorized belt 12 will operate substantially the same way as a motorized version. Instead, in the unmotorized preferred embodiment, the belt 12 has adjustable tension or resistance applied thereto for speed control, which may be under the control computer system 21 or manually set. Deviation from the desired pressure (as, for example, as determined from the exercise “program” executed by computer system 21) may then be displayed to the user so that he/she can adjust their level of desired exertion. In addition, the elevation angle of the belt 12 should be no more than 15° in either direction (e.g. “uphill” or “downhill”.)
In
Vertical member 41 is coupled to a pressure sensor 44 via a coupling member 45. Similar to that described above, coupling member 45 may be immovably affixed to the vertical member 41 or has an adjustable feature to allow member 45 to be adjusted in length where attached to coupling member 45 to allow for adjustment in height of receiver 18 by the user.
Pressure sensor 44 has therein a conventional pressure transducer (not shown), such as a strain gauge, to measure the horizontal component of pressure exerted on member 45. Such pressure sensors are well known in the art and should be insensitive to any torque moment resulting from pressure applied by the user to receiver 18. As will be appreciated by someone skilled in the art, an alternative placement of a pressure sensor may be done where receiver 18 is attached to coupler 42. With this configuration, communication from the sensor to computer 21 (
It is understood that the belt 12 may be bi-directional allowing the user to operate the treadmill 10 in reverse or “backward” with the user applying his/her back against the pressure receiver 18, the elevation or tilt may be in either “uphill” or “downhill” direction, as well as also allowing use of an exercise “program” in computer system 21. With such an arrangement, because the control panel 30 is now behind the user, an alternative or supplemental display may be desired (not shown). Alternatively, aural feedback indicating deviation from the desired pressure on receiver 18 and/or the speed of belt 12 could be indicated by a tone pitch or pulse rate. Preferably when the user is walking backward on the treadmill 10, the pressure receiver 18 is positioned against the rhomboid region of the user's back, such as between the shoulder blades of the user. With this arrangement and the user applying an approximately constant pressure, the exemplary quadriceps and lower back muscle groups may then be exercised.
Having described the preferred embodiment of this invention, it will now be apparent to one of skill in the art that other embodiments incorporating its concept may be used. Therefore, this invention should not be limited to the disclosed embodiment, but rather should be limited only by the spirit and scope of the appended claims.
