1. Field
The present invention relates to an arm exercise apparatus that simulates the arm movements of running and jogging. More particularly, the present invention is associated with an exercise machine having separately supported pedals for the feet combining coordinated arm exercise with the motion of the feet.
2. State of the Art
The benefits of regular exercise to improve overall health, appearance and longevity are well documented in the literature. For exercise enthusiasts the search continues for safe apparatus that provides total body exercise for maximum benefit in minimum time.
Elliptical cross trainers guide the feet through generally elliptical paths on pedals having pedal angles controlled to simulate the foot motion during running and jogging. Typical rear drive cross trainers with arm exercise are found in Eschenbach U.S. Pat. No. 7,025,711 and Arnold et al. U.S. Pat. No. 6,238,321. A front drive cross trainer with arm exercise is shown in Eschenbach U.S. Pat. No. 6,422,976. The handles used for arm exercise typically rotate back and forth coordinated with the elliptical foot motion. Hand grips are generally positioned on the handle to move back and forth at shoulder height. A study of the hand motion of someone free running shows that the hand motion begins on the side of a runner around the hip region moving forward and towards the sagittal plane of the runner while the foot on the other side of a free runner moves to the rear. The motion of shoulder height hand grip handles are not even close to the proper free running hand motion desired. May et al. in U.S. Pat. Application No. 2006/0199701 provides an independent inclined hand movement as some improvement over the rotary handle.
There remains a need to more accurately simulate the hand movements common to running and jogging in conjunction with the foot motion of an elliptical device. There also remains a need for an exercise apparatus that provides adjustable running hand motion to suit the operator.
The present invention relates to the kinematic motion control of handles which simulate running during operation. More particularly, apparatus is provided that offers running hand motion coordinated with the foot motion of elliptical cross trainers.
In the preferred embodiment, the apparatus includes a pair of handles each having a hand engaging grip supported by a pair of linkage systems that guides each hand grip along inclined arcuate paths. Each linkage system is comprised of a first link and a second link, each link pivotally connected to the handle and a frame. Hand motion begins on the side of an operator near the hip region and moves forward towards the sagittal plane of the operator or apparatus. The frame pivots for the second links are closer together than the frame pivots for the first links to cause hand grip movement forward towards the sagittal plane of an operator.
Each handle contains a pivot allowing the hand grip to rotate towards the center of an operator. A coupler link is pivotally connected to each handle and first link to control the amount of rotation. Adjustment is provided to change the amount of rotation to suit an operator. Each linkage system is coordinated with the pedal movements of a foot driven exercise device by connecting links. The arm exercise apparatus delineated herein can also be applied to other foot exercise devices such as steppers, treadclimbers, stationary bikes, etc.
In summary, this invention provides the operator with arm exercise closely simulating the natural arm movements in free running. Moreover, the arm motion is coordinated with the foot motions of a foot driven exercise device.
The foregoing and other objects and features of the present invention will become more fully apparent from the following description and claims, taken in conjunction with the drawings. Understanding that these drawings depict only typical embodiments of the invention and are, therefore, not to be considered limiting of its scope or combinations, the invention will be described with additional specificity and detail through use of the accompanying drawings in which:
Referring to the drawings in detail, handles 20,22 are shown in
Handles 20,22 are connected to handle extensions 26,28. First links 30,32 are connected to handle extensions 26,28 at pivots 21,23. Second links 34,36 are connected to handle extensions 26,28 at pivots 25,27. First links 30,32 are connected to framework member 51 at pivots 29 and 59 while second links 34,36 are connected to framework member 51 at pivots 31 and 157. Note that pivots 31 and 157 are closer together than pivots 29 and 59 as shown in
Pivots 55,57 are positioned between handles 20,22 and handle extensions 26,28 as an option to allow rotation of hand grips 24,26. Control links 38,40 are connected to handles 20,22 at pivots 33,35 and to first links 30,32 at pivots 37,39. Adjustment holes 11,13 on handles 20,22 allow repositioning of control links 38,40 to change the amount of hand grip 24a,24b rotation. As shown in
Connecting links 42,44 are connected to first links 30,32 at pivots 45,47 and to rocker links 50,52 at pivots 41,43. Rocker links 50,52 are connected to frame member 62 at pivot 53.
By previous examples, the preferred embodiment of the arm exercise apparatus of the present invention is shown coordinated with three different types of elliptical cross trainers. The arm exercise apparatus may also be coordinated with other foot driven exercise devices not shown here.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative, and not restrictive. The scope of the invention is, therefore, indicated by the claims, rather than by foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
