Abstract
An aerobic exerciser with elongated stride comprising a frame, a seat supported from the frame, a bell crank, a left telescoping pedal rail rotatably attached to the left side of the bell crank at one end and pivotally attached to the frame at the other end, and a right telescoping pedal rail rotatably attached to the right side of the bell crank at one end and pivotally attached to the frame at the other end.
In operation, under the weight of the user, each pedal, supported by a pedal rail follows a generally elliptical path in response to rotation of the bell crank. Vertical movement of a telescoping pedal rail is accommodated by the pivot and horizontal movement of the pedal rail results in extension and retraction of the pedal rail.
Description
- This application relies upon provisional application Ser. No. 60/784,279 filed in the United States Patent Office on Mar. 21, 2006.
- 1. Field of the Invention
- This invention relates generally to an aerobic exercise machine. More particularly, but not by way of limitation, the present invention relates to a recumbent elliptical exercise apparatus with elongated stride.
- 2. Background
- Although offered by various manufacturers under a variety of generic names, generally speaking, an elliptical exerciser is an aerobic exercise machine wherein the user's feet travel in a generally elongated elliptical path while the user walks, jogs, runs, or climbs. Many elliptical exercisers include a feature for simultaneously exercising the upper body.
- There are many advantages to using a mechanical device to aerobically train rather than simply running or jogging. For example, such machines typically provide the user with meaningful feedback in regard to the exercise performed. For example, a typical aerobic exercise machine may provide the user with a real-time display of power produced by the user (i.e. Watts), as well as totalizing displays of information such as calories expended or equivalent miles run. In addition, properly designed equipment reduces the risk of injury, and, as part of a rehabilitation program, allows easy monitoring by a therapist.
- Elliptical exercisers have proven to provide a quantifiable, low impact workout with meaningful results, and are, therefore, a viable alternative to treadmills, stationary bicycles, stair climbers, rowing machines, and the like. In that regard, elliptical exercisers have thus far been very popular in relation to other aerobic machines.
- In a typical elliptical exerciser, the user's feet rest on individual pedals which are mounted on rails. A first end of each rail is attached to a bell crank such that the first end of each rail travels in a circular path. The left end of the bell crank is 180 degrees out of phase with the right end of the bell crank such that as one foot moves forward, the other foot moves backward and as one foot moves up, the other foot moves down. The second end of each rail, depending on the particular machine, is constrained to move in a track, over a fixed roller, or guided by a swing arm, thereby producing backward and forward motion in response to the movement of the bell crank. The resulting stride of each foot of the user follows a generally elliptical path. The exact dimensions of the ellipse are dependant on a variety of variables such as the length of the rail, the position of each pedal on its rail, the diameter of the circle traveled by the bell crank, and the path traversed by the end of the rail opposite the bell crank. The perceived level of difficulty in using an elliptical exerciser and the comfort of the user are also dependant on these variables.
- A limitation of a typical elliptical exerciser is the amount of floor space occupied by the machine. Whether in a home, a health club, or a rehabilitation facility, ideally, an exercise machine will occupy as little floor space as possible, especially where such floor space is rented by the square foot. The size of an elliptical exerciser is dictated by, among other things, the length of the pedal rails and the space required to allow the horizontal movement of the rails in response to the motion of the bell crank.
- Another related limitation arises from the hazzard produced by the movement of the rail end opposite the bell crank. This is especially true with elliptical exercisers where the rails move outside the footprint of the frame of the machine. A person walking near the machine may be struck by a rail or trip over a rail. Accordingly, many manufacturers provide a cover over the end of the rails, adding cost and further occupying floor space.
- A further limitation of many elliptical exerciser designs is that some machines have a roller on the free end of the pedal rail or a pivot on a swing arm very close to the floor. It has been a common practice for some health clubs to place exercise machines near a swimming pool. In addition, some facilities pour excessive water on the floor during cleaning. Either of these situations will subject rollers and pivots placed near the floor to potential water damage.
- It is thus an object of the present invention to provide an elliptical exerciser wherein, the back end of the pedal rails pivot from a fixed position, rather than swinging in an arc, traversing a fixed roller, or moving in a track, while still allowing the front end of the rails to traverse a circular path.
- It is a further object of the present invention to locate rotating or oscillating components of the pedal rails a sufficient distance above the floor to avoid subjecting such components to water in a typical commercial or institutional environment.
- It is a still further object of the present invention to provide a seat on the exercise apparatus for the user to sit upon whereby the apparatus becomes a recumbent elliptical exercise device.
- The present invention provides an elliptical exerciser which incorporates a telescoping rail mechanism wherein, the back end of the rail merely pivots, rather than moving linearly or swinging in an arc. The horizontal component of the motion created by the bell crank is accommodated by the telescopic rail. The vertical component of the motion is accommodated by the pivot.
- In the inventive elliptical stepper, a front portion of each rail connects to the corresponding end of a bell crank. The back end of each rail connects to a pivot which is provided on the frame, preferably several inches above the floor surface. The front portion of the rail is in sliding engagement with the rear portion the rail such that the rail is rigid in regards to vertical forces but will telescopically extend or retract in response to tensile or compressive forces, respectively.
- Further objects, features, and advantages of the present invention will be apparent to those skilled in the art upon examining the accompanying drawings and upon reading the following description of the preferred embodiments.

FIG. 17 is a view similar toFIG. 1 but showing details of a preferred recumbent embodiment of the invention. - The preferred embodiment of the inventive
aerobic exercise apparatus 20 with elongated stride is shown in its general environment inFIGS. 1 and 2 .Aerobic exercise apparatus 20 comprises:frame 22 supported byfront leg 24 andrear leg 26;left cover 28 enclosing the left side of the upright portion offrame 22; likewise,right cover 30 enclosing the right side of the upright portion offrame 22; bell crank 32 extending through an aperture (not shown) provided inleft enclosure 28 andaperture 34 provided inright cover 30;handrail 36 secured to frame 22;electronic console 38; left telescopingpedal rail 40; and righttelescoping pedal rail 42. - Bell crank 32 is in mechanical communication with a brake assembly under the control of
electronic console 38. Such breaking systems are known in the art and not a part of the present invention. - Preferably, right
telescoping pedal rail 42 includesfront portion 44 andrear portion 46. As best seen inFIGS. 3 and 4 , bushing 48 extends throughfront portion 44 for rotatably attachingtelescopic pedal rail 42 to bell crank 32. Similarly, as best seen inFIGS. 13 and 14 in combination withFIG. 1 ,rear portion 46 includesbushing 50 for pivotally attachingtelescopic rail 42 to apivot 52 onrear leg 26. - Likewise, as shown in
FIG. 2 , left telescopingpedal arm 40 includesfront portion 54 andrear portion 56.Front portion 54 rotatably attaches to bell crank 32 andrear portion 56 pivotally attaches to pivot 58 onrear leg 26. - As will be apparent to those skilled in the art, left telescoping
pedal rail 40 is the mirror image of righttelescoping pedal rail 42 and any discussion with reference to either rail applies equally to the other rail. For the sake of convenience, the discussion of the construction and operation of inventive telescoping pedal rails 40 and 42 will be addressed primarily with respect to the righttelescoping pedal rail 42, and it is to be understood that such discussion also applies to the lefttelescoping pedal rail 40. - Referring now to
FIGS. 8 and 9 , preferablyfront portion 44 is tubular and includes:pedal support 60 extending upward therefrom;first roller support 61 rotatably securingrollers roller 64 extends throughnotch 70 infront portion 44; andsecond roller support 72 rotatably supportingrollers rollers aperture 74 provided infront portion 44. When telescopingpedal rail 42 is assembled,rear portion 46 is slidingly received infront portion 44 such that rollers 62-68 support rear portion 46 (FIGS. 6 , 7, 8, and 10) to constrain the vertical movement ofrear portion 46 relative tofront portion 44. - Continuing to refer to
FIG. 10 ,front portion 44 includes horizontal roller supports 78 which rotatablysupport rollers 80 such thatrollers 80 will rollingly contact thesides 81 ofrear member 46 when such contact occurs. Referring now toFIG. 15 in conjunction withFIG. 10 ,rollers 96 are rotatably supported on the end ofrear portion 46 such thatrollers 96 will rollingly contact theinside side wall 82 offront portion 44 to the extent such contact occurs.Rollers 96 operate in conjunction withrollers 80 to maintainhorizontal gap 98 between theside walls 82 offront portion 44 and thesides 81 ofrear portion 46. - As best seen in
FIG. 11 , preferably,pedal 84 is pivotally attached to support 60 and includes: stop 86 to limit mechanical travel ofpedal 84;bottom plate 88; andpad 90 to receive the users foot. - Referring again to
FIG. 1 , in operation, a user prepares for operation of the inventiveaerobic exerciser 20 by first stepping ontopedals 84. The user begins operation of the machine by shifting her weight to one foot which provides a downward force on that pedal which in turn presents a downward force on the bell crank 32 which causes bell crank 32 to begin rotating. As the front end of a pedal rail passes the bottom of its circular path, as shown by the position of the righttelescoping pedal rail 42 inFIG. 1 , the user shifts her weight to the other pedal, thereby continuing to force bell crank 32 to rotate. - As bell crank 32 rotates from the position shown in
FIG. 1 to the position shown inFIG. 2 , the front portion of each pedal rail is simultaneously subjected to vertical movement and horizontal movement. The vertical component of the movement causes pivotal movement of telescoping pedal rails 40 and 42 atpivots FIGS. 6 and 12 , when bell crank 32 is rotated to the point where thefront portion 44 is at itsrearmost position 92,telescoping pedal rail 42 is fully retracted. Conversely, when bell crank 32 is rotated to the point where thefront portion 44 is at its most forward position 94 (FIG. 7 ),telescoping pedal rail 42 is fully extended. The resulting stride which is presented to the user at each pedal 84 follows a generally elliptical path. - As will be apparent to those skilled in the art, an aerobic exerciser which incorporates the inventive telescoping pedal rail does not require additional space beyond the back of the machine to accommodate motion of the pedal rail. It will also be apparent that there is no movement outside of the frame of the exerciser thereby reducing risk to other people near the machine.
- In an alternate embodiment, as shown in
FIG. 16 ,rollers 100 are rotatably supported onrear portion 102 and roll along the inside walls offront portion 104.Roller 106 maintains a gap to prevents side-to-side contact betweenrear portion 102 andfront portion 104.Front portion 104 includesroller support 108 androller 110 to provide additional vertical support betweenfront portion 104 andrear portion 102. -
FIG. 17 represents the preferred embodiments of this invention. Whereas theframe 20 of the exercise device shown inFIG. 17 is similar in many respects to the exercise frame shown in the embodiments illustrated byFIGS. 1 through 16 , the preferred embodiments ofFIG. 17 differs principally in that it calls for a recumbent elliptical exercise device whose main recumbent feature involves aseat 200 having a seat back 202 mounted on aseat frame 204. Theseat 200 is mounted on aroller mechanism 206 which includes a plurality ofrollers 208 mounted for rolling movement within atrack 210 on aninclined track support 210′. Theexercise machine 20 ofFIG. 17 also includes a lowerhorizontal frame 22 connecting with aforward leg 212 and arear leg 214. The lower frame which is supplied in the area encompassed by thelower frame 22,forward leg 212,rear leg 214 andtrack frame 210′ there are included apower supply 216, a fly-wheel 218 and abell crank 220. Also shown is adynamic braking system 222. - The system also includes a
left foot bed 224 attached to aleft telescoping rail 226 and aright foot bed 228 attached to a right telescoping rail (obscured by the left telescoping rail 226). Mounted at the upper end of the arcuate vertical frame is acontrol panel 230 and the device is provided with a right arm crank 282 and a left arm crank 284 which are connected respectively to the forward ends of the unseen obscured right telescoping rail and theleft telescoping rail 226 througharms 286. Left arm crank 284 is pivotally connected intermediate its ends at 288 to astationary arm 290 which extends from the curvedvertical support 20 as shown. Similar connection is provided for the right arm crank 282.Rollers 292 are located at the forward end of thehorizontal frame 22 andrear rollers 294 are mounted at the rear end of thehorizontal frame member 22 to permit movement of theentire exercise device 20, if desired. Theseat 200 is provided with ahandle 296 to permit release of the seat when desired. Also provided are seat adjustment knobs 298. - As will be further understood by those skilled in the art, although the earlier preferred embodiments of the inventive apparatus have been discussed in regard to pedals such as
pedals 84, which are pivotally attached, a rigid pedal attachment such aspedals - The terms “front” and “back’ as used herein are merely temporarily convenient descriptive terms for the purposes of a given figure or embodiment; that is, when referring to the apparatus shown in
FIGS. 1 to 16 , the “front” end is generally to the right on these figures as typified by the location of theconsole 38 and/or thebell crank 32. However, in the embodiment shown inFIG. 17 , the “front” of the device is at the left as typified by the location of theconsole 230; inFIG. 17 , the bell crank 220 is to the “back” or rear end of the device below theseat 200. Thus, the terms “front” and “back” are in fact reversed forFIG. 17 . Therefore, these terms should not be considered as limiting; parts which operate on the front in one figure might very well operate on the back or rear end in another figure. - Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned above as well as those inherent therein. While presently preferred embodiments have been described for purposes of this disclosure, numerous changes and modifications will be apparent to those skilled in the art. Such changes and modifications are encompassed within the spirit of this invention as defined by the appended claims.
