Abstract

An exercise device includes a frame (12) having a set of guide links (24, 26) pivotally supported thereupon. Each guide link supports a foot engaging support or link (28, 30) at one end thereof. The guide links are reciprocated back and forth by a set of intermediate links (40, 46) which engage a set of cranks or coupler arms (36, 38) which rotate about a second pivot point. A control link (44, 48) joins the foot link to the intermediate link and operates to vary the angle between the guide links and the foot links, as the guide links reciprocate. This device provides a very natural running and stepping action for a user who is positioned on the foot links.

Claims

AMENDED CLAIMS"[received by the International Bureau on 30 July 1997 (3007.97), original claims 1 and 9 amended; remaining claims unchanged (2 pages)]The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. An exercise device comprising:
a frame having a first and a second pivot axis defined thereupon;
a first and a second guide link, each guide link having a first and a second
attachment point defined thereupon, each guide link being pivotally attached, through
its first attachment point, to said frame at the first pivot axis thereof;
a first and a second foot link, each foot link being pivotally attached to a
respective one of said first and second guide links through the second attachment point
thereof; coupling means coupled relative to the second pivot axis to rotate thereabout,
and operably associated with said guide links for causing said guide links to pivot about
said first pivot axis as said coupling means rotate about said second pivot axis; and
control means mechanically associated with said foot links, said control means
being operative to control an angle defined between one of said foot links and its
associated guide link as said guide link pivots about said first pivot axis.
2. An exercise device according to Claim 1, wherein said coupling means
comprising a first and second intermediate link, each having a first connection point
mechanically coupled to a respective one of said guide links and a second connection
point mechanically coupled relative to the second pivot axis to rotate thereabout so that
rotation of said first and second intermediate links about said second pivot axis causes
said respective first and second guide links to pivot about said first pivot axis.
3. An exercise device according to Claim 2, wherein said first and second
intermediate links are each coupled to their respective guide links at third attachment point defined on each of said guide links between said first and second attachment
points.
4. An exercise device according to Claim 2, further comprising a first and
second coupler arm, each coupler arm being pivotally attached to the frame at said
second pivot axis so as to be rotatable thereabout, the coupler arms being mechanically
coupled to a respective first and second intermediate link at the second connection point of the respective intermediate links.
5. An exercise device according to Claim 4, further comprising a flywheel
in mechanical engagement with the first and second coupler arms.
6. An exercise apparatus according to Claim 5, wherein the first and
second coupler arms are defined by integral portions of the flywheel.
7. An exercise apparatus according to Claim 5, wherein said flywheel is
supported a pivot axis separate from said second pivot axis, and wherein said flywheel
is mechanically coupled to said first and second coupler arms so that said first and
second coupler arms rotate about said second axis as said flywheel rotates.
8. An apparatus according to Claim 4, wherein said coupler arms
comprising first and second crank arms each pivotally attached to the frame at the
second pivot axis so as to rotate thereabout, with the distal ends of each crank arms
mechanically coupled to a respective first and second intermediate link at the second
connection point thereof.
9. An apparatus according to Claim 2, wherein said control means
comprising a first and second control link, each having a first end operably coupled to a
respective one of said foot links, and a second end portion operably coupled to a
