Abstract
Description
- The present invention relates generally to exercise equipment and, more particularly, to exercise equipment which can be used to provide a user with an elliptical step exercise.
- There are a number of different types of exercise apparatuses that exercise a user's lower body by providing a generally elliptical stepping motion. These elliptical stepping apparatuses provide advantages over other types of exercise apparatuses. For example, the elliptical stepping motion generally reduces shock on the user's knees as can occur when a treadmill is used. In addition, elliptical stepping apparatuses tend to produce a more natural foot motion than certain other types of exercise equipment. Examples of elliptical stepping apparatuses include U.S. Pat. Nos. 3,316,898; 5,242,343; 5,383,829; 5,499,956; 5,685,804; 5,759,136; 5,762,588; 5,779,599; 5,792,026; 5,899,833, 6,099,439 and 6,217,486.
- However, known elliptical stepping exercise apparatuses suffer from various drawbacks. For example, some apparatuses are limited to certain predetermined elliptical paths and thus are limited to certain foot motions.
- It is therefore it is one object of the invention to provide an elliptical stepping exercise apparatus that can be adjusted to vary the elliptical path of a foot supporting member.
- Another object of the invention is to provide an elliptical stepping apparatus that can be adjusted to the individual needs and desires of different users.

FIG. 1 is an example of anelliptical step apparatus 10 which provides an illustrative environment for describing the invention. It will be appreciated that the invention can be used in many other elliptical step mechanisms such as the mechanisms described in the patents listed above. For simplicity,FIG. 1 provides a perspective view of the components of the left portion of theapparatus 10, although it is to be understood, that the right portion of theapparatus 10 would include like components that operate in a like fashion. - As shown in
FIG. 1 , the representativeelliptical step apparatus 10 includes a frame, shown generally at 12. Theframe 12 includes a set ofvertical support members longitudinal support member 18. Theframe 12 further includes a pair ofmembers longitudinal support member 18 and are configured for placement on a floor 24 or other generally horizontal support surface. Theapparatus 10 further includes arocker 30, apedal 32, a pedal actuation assembly indicated at 34 and a resistance assembly indicated. In this example of an elliptical step apparatus, themotion controlling assembly 36 includes apulley 38 mounted for rotation on anaxel 40 along with resistive force and control components including analternator 42 of the type described in more detail in U.S. Pat. No. 6,217,486. Also in this example 10 of an elliptical step apparatus, the pedal actuation assembly 34 includes apedal lever 44 and astroke link 46 connected to thepedal 32 at one end and connected to anextension arm 48 at the other end. In addition the pedal actuation assembly 34 includes, and acrank member 50 having theextension arm 48 attached to its distal end and rotatable around theaxel 40 with aroller 52 also mounted for rotation on its distal end for supporting the rearward portion of thepedal lever 44. As illustrated inFIG. 1 , thecrank 50 is pivotally coupled betweenpivot axle 40 and theroller 48 in a manner similar to that disclosed in the aforementioned '486 Patent. In thisembodiment 10, therocker 30 provides a generally linear or horizontal movement to the forward end of thepedal lever 44 and the pedal actuation assembly 34 provides a vertical as well as horizontal motion to the rearward end of thepedal lever 44 resulting in a generally elliptical foot path for thepedal 32 with its major axis generally parallel to the floor 24. This type of motion can be achieved by other arrangements such as having the first end of the pedal lever move along a linear or curved track. By the same token, a pedal actuation assembly can include a variety of other mechanical arrangements to achieve motion of the rearward end of thepedal lever 44 in a generally elliptical or circular motion with respect to thepivot axel 40 including simply connecting of this end of thepedal lever 44 directly to thecrank 52. - In order to provide a method of repositioning the
pedal 32 on thepedal lever 44, the preferred embodiment ofexercise apparatus 10 includes a mechanism for selectively moving thepedal 32 into different positions along the length of thepedal lever 44. As shown ifFIG. 1 , the each side of thepedal 32 is configured with a pair of downwardly extendingbrackets 54 effective to retain thepedal 32 on an upper planar 56 surface of the pedal lever 34 while permitting thepedal 32 to move forward and aft along thepedal lever 44. In this embodiment of the invention, anactuator assembly 58 is secured to thepedal lever 44 and thepedal 32. In this arrangement, theactuator assembly 58 includes ashaft 60 secured at each end to thepedal lever 44 and a linear motor mounted 62 on theshaft 60 and attached to thepedal bracket 54. It should be noted that theactuator assembly 58 can be located on either side as well as the top or bottom of thepedal lever 44 depending upon the characteristics of a particular design of theapparatus 10. Thelinear actuators 62 are coupled to thepedals 32 such that thepedal 32 can be moved along theupper surface 56 of thepedal lever 44 between an aft position, see the foot path ellipse A inFIG. 2 ; an intermediate position, see the foot path ellipse B inFIG. 2 ; and a forward position, see the foot path ellipse C inFIG. 2 . Each of these various positions can produce a modified elliptical path capable of simulating a downhill, neutral, or an uphill gait. - In this
particular mechanism 10, thestroke link 46 is pivotally interconnected betweenpedal 32 andcrank 50 and has a fixed length. Accordingly, aspedal 32 is placed in different locations along the top of the pedal lever 34 by theactuator mechanism 58, the corresponding shape of the elliptical path traversed by thepedal 32 will be substantially the same for each position but the major axis of the ellipse will be in either an inclined position, an intermediate position, or a declined position with respect to the floor 24. This variation in the elliptical path ofpedal 32 is illustrated by the ellipses A, B and C inFIG. 2 . -
FIG. 2 provides an illustration of an arrangement producing the elliptical path A generally inclined upwardly with respect to the floor 24. Specifically,FIG. 2 showsexercise apparatus 10 in one of four stages of rotation—thecrank 50 at 0°, 90°, 180°, and 270°. As can be seen for ellipse A, thepedal 32 is positioned in a far aft position relative to thepedal lever 44. In other words, theactuator mechanism 58 has moved thepedal 32 rearward. Becausestroke link 46 is a fixed length, this movement of thepedal 32 rearward causes thepedal lever 44 to be driven forward and therocker 30 in a clockwise direction. A consequence of varying the relative geometry of the system is a tilted elliptical path. As can be seen inFIG. 2 , a generally elliptical path A is traversed by thefoot pedal 32 throughout the cycle. The major axis of the elliptical path A is inclined to the upwardly and thus serves to simulate an uphill gait. -
FIG. 2 Illustrates an arrangement producing the generally horizontal elliptical path B. Here, thepedal 32 is positioned in an intermediate position relative on thepedal lever 44. In other words, theactuator mechanism 58 has moved thepedal 32 to an intermediate position between its rearward and forward positions. Again becausestroke link 46 is a fixed length, this movement of thepedal 32 forward causes thepedal lever 44 to be driven to a neutral position and therocker 30 in a counter-clockwise direction relative to the aforementioned “inclined”. A consequence of varying the relative geometry of the system is that the elliptical path B has a modified orientation. As can be seen inFIG. 2 , the elliptical path B is traverses throughout the cycle. The elliptical path B is less-inclined than that described in connection with the elliptical path A and serves to simulate a horizontal gait. In other words, the major axis of the elliptical path B is generally parallel to a horizontal plane or the floor 24. -
FIG. 2 shows an arrangement producing an elliptical path C that is tilted downwardly with respect to the floor 24. As illustrated, thepedal 32 is positioned in a forward position on thepedal lever 44, that is, theactuator assembly 58 has been used to move thepedal 32 to its most forward position. As before, a consequence of this varying of the relative geometry of the system is the elliptical path C. As can be seen inFIG. 2 , the elliptical path C is declined to the left in the figure and serves to simulate a downhill gait. In other words, the major axis of the elliptical path C is declined relative to a horizontal plane. -
FIG. 3 is a combined schematic and block diagram that provides a further illustration of the invention and a preferred method of operation. The mechanical portions of theelliptical step apparatus 10 are shown in schematic form with, again, only one side of theapparatus 10 illustrated. Amicroprocessor 200 contained within aconsole 202 is used to control theactuator mechanisms 58 via asignal line 204. As is conventional in exercise apparatus, adata input center 206 is included in theconsole 202 and generally includes akeyboard 207 and various switches to allow a user to input data and to control the apparatus. -
FIG. 4 provides a view of theconsole 202 where, as is conventional theconsole 202 includes various displays such as avideo display 208 and a set of LED indicators or displays 210. In one embodiment of the invention, thedata center 206 can include aswitch 212, shown inFIG. 4 , that for purposes of describing this embodiment of the invention can be termed a “stride incline” switch. In this embodiment, operation of thestride incline switch 212 will cause themicroprocessor 200 to activate theactuators 58 so as to reposition thepedals 32 along the pedal levers 44 thus altering the orientation of the pedal ellipse path. For example, the user can use theincline switch 212 to selectively change the incline of the ellipse as shown inFIG. 2 . Also, the location of thepedals 32 or the degree of incline can be shown on thedisplay 208. In some embodiments of the invention it would also be desirable to equip the pedal levers 44 or theactuator mechanisms 58 with position sensors to provide themicroprocessor 200 with a positive indication of the location of thepedals 32 on the pedal levers 44. Similarly, themicroprocessor 200 can be programmed to insure that thelactuators 58 move bothpedals 32 at the same time and in the same direction as well as being located in the same relative position on the pedal levers. Additionally, themicroprocessor 200 can be programmed with user programs that would for example provide an interval type exercise workout where the incline of the ellipse varies periodically from horizontal to either a positive or negative inclination. Thus, an elliptical step apparatus of thetype 10 as described above, can provide a wide variety of exercise programs simulating either a downhill, neutral, or uphill gait without the need for risers or other cumbersome structures and further the apparatus can be tailored to meet an individual user's unique tastes or training desires. - The foregoing description of the invention is merely exemplary in nature. The invention was described in terms of an elliptical step apparatus of the type shown in U.S. Pat. No. 6,217,486 where a pedal lever rides on a roller attached to a crank arm. However, there are a large variety of elliptical step mechanisms, such as the devices shown in U.S. Pat. Nos. 5,383,829, 6,176,814 and 6,099,439 where the relative position of a foot pedal on a pedal lever or its equivalent can be selectively changed in order to alter the orientation of the generally elliptical path of a user's foot motion. As an example, in an elliptical step apparatus where the pedal lever is connected directly to the end of the
crank 50 and astroke link 46 androller 52 are not used, theactuator mechanism 58 can still be used with the pedal lever of thetype 56 as shown. Moreover, the specific mechanical components described represent the preferred embodiment of the invention in terms of theparticular apparatus 10 used as the environment for describing the invention and as a result, depending upon the size, cost and other factors the use of other components might become desirable. For example, theactuator mechanisms 58 are described as electrically operatedlinear actuators 62 but other actuators such as hydraulic actuators can be used for certain applications. By the same token, in some applications, it might be desirable to use a manually operated pedal mounting mechanism for selectively locating a pedal on a pedal lever or its equivalent where such a mechanism might include a simple pin and hole arrangement or a mechanical latch.
