Therapeutic exercise device

Claim 2

A therapeutic exercise device particularly adapted for exercising the limbs of a human which limbs may be paralyzed or impaired and said device adapted for use in conjunction with a body support member comprising: a base adapted to be fixedly positioned adjacent a body support member; first means pivotally mounted on said base adapted to be engaged by the hands of the user; second means pivotally mounted on said base adapted to be engaged by the fact of the user; rigid linkage means interconnecting said first and second means for simultaneous movement of both said means in one direction or the other; and yieldable resistance means coupling said base and one of said first or second means to provide a force to be overcome by the user in pivoting said first or second means.

Claim 3

A therapeutic exercise device as defined in claim 1 wherein said pivotally mounted first means comprises a rigid, elongated hand lever, hand support means including means for securing the wrists of said user to said support means, and a plurality of adjustment holes for the mounting of said linkage means at multiple positions on said hand lever.

Claim 4

A therapeutic exercise device as defined in claim 1 wherein said pivotally mounted second means comprIses a rigid, elongated foot support lever, a foot support pedal pivotally mounted upon said lever to engage the feet of said user, yieldable pedal resistance means forming a second coupling between said lever and said foot support pedal, and a plurality of adjustment holes for the mounting of said foot support pedal, said linkage means, and said resistance means at multiple positions on said foot support lever.

Claim 5

A therapeutic exercise device as defined in claim 1 wherein said base comprises parallel, spaced apart, channel members having a plurality of aligned adjustment holes whereby said first means, said second means, and said resistance means may be pivotally mounted at multiple, selectable positions along said base to vary the amount of force necessary to overcome said yieldable resistance means.

Claim 6

A therapeutic exercise device particularly adapted for exercising limbs of a human, which limbs may be paralyzed or impaired and said device adapted for use in conjunction with a body support member comprising: a stationary base positionable in an aligned adjacent relationship with said body support member; foot lever means pivotally secured to said base and projecting vertically therefrom, for movement toward and away from said body support member and including a foot support to receive the feet of said human; hand lever means pivotally secured to said base and projecting vertically therefrom and adapted to pivot in a common vertical plane with said foot lever means and spaced from said foot lever means and including a hand support to receive the hands of said human; rigid link means above said base secured to said foot lever means and said hand lever means whereby pivoting of one of said means will simultaneously impart pivoting to said other means; and yieldable tension means extending from said base to one of said pivot means biasing one of said pivot means yet yieldable upon pivotal movement of one of said pivot means whereby said biasing may be overcome and said pivot means are pivoted and the limbs of said human are flexed.

Claim 7

A therapeutic exercise device particularly adapted for exercising limbs of a human, which limbs may be paralyzed or impaired and said device adapted for use in conjunction with a body support member comprising: a stationary base positionable in an aligned adjacent relationship with said body support member; foot lever means pivotally secured to said base and projecting vertically therefrom, for movement toward and away from said body support member and including a foot support to receive the feet of said human; hand lever means pivotally secured to said base and projecting vertically therefrom and adapted to pivot in a common vertical plane with said foot lever means and spaced from said foot lever means and including a hand support to receive the hands of said human; rigid link means above said base secured to said foot lever means and said hand lever means whereby pivoting of one of said means will simultaneously impart pivoting to said other means; and yieldable tension means extending from said base to one of said pivot means biasing one of said pivot means yet yieldable upon pivotal movement of one of said pivot means whereby said biasing may be overcome and said pivot means are pivoted and the limbs of said human are flexed.

Claim 8

A therapeutic exercise device as defined in claim 5 wherein said yieldable tension means is a tension spring interposed between said base and said foot lever, whereby movement away from said body support member of said foot or said hand lever will overcome said tension, and said spring is adjustable to vary the tension thereof.

Claim 9

A therapeutic exercise device as defined in claim 5 wherein power means is associated with said one of said lever means to pivot said lever means and overcome said yieldable tension means.

Claim 10

A therapeutic exercise device as defined in claim 5 wherein said foot lever means, said hand lever and said rigid link means each contain a plurality of adjustment settings whereby the respective interconnections may be changed.

Claim 11

A therapeutic exercise device as defined in claim 5 wherein said device includes stabilizing means adapted to be fixedly positionable with respect to said body support member.

Claim 12

A therapeutic exercise device as defined in claim 5 wherein an auxiliary hand lever is connected to said foot lever means whereby external manual force may be used to activate said device.
