Abstract

Abstract The invention is an aerobic exercise machine for exercising all major muscles simultaneously. The aerobic exercise machine includes a horizontal frame with an attached seat and two foot pedals. Two handgrips are provided at an upper end of a hand lever. The hand lever is pivotably mounted on the machine to be in front and slightly above an operator's pelvic area. The foot pedals are on the bottom end of a foot lever that is pivotably mounted directly forward of the handgrips. The hand and foot levers are connected by a separate cable to a common junction that connects to a flat belt which travels up through a vertical support over two flat pulleys and then down to a stack of free weights. The hand lever cable has an extra pulley which increases the leverage in order to more nearly match the stronger push of the leg muscles.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 307 words
An aerobic exercising machine that works all the major body muscles simultaneously comprising: a. a vertical beam having a cross arm at the foot end and a forward extension at the top end, said forward extension supporting a plurality of free weights; b. a horizontal beam pivotally connected to said vertical beam by a plate means at approximately one third the height of said vertical beam; c. a rear leg support pivotally connected to said horizontal beam at the end opposite said vertical beam connection; d. an adjustable sloping seat bolted to a seat bracket attached to the horizontal beam above the rear leg support; an adjustable sloping seat connected to said horizontal beam above said rear leg support; e. a foot lever pivotally attached to the top of said vertical beam, the bottom end of said foot lever having a pair of foot pedals, said foot pedals straddling said horizontal beam; f. a vertical support connected to said horizontal beam directly forward of said seat, said vertical support having a hand lever pivotally attached thereto, the upper end of said hand lever having a pair of handgrips; g. a first pulley means operatively connected to said forward extension, a second pulley means operatively connected to said plate means, a third pulley means operatively connected to said hand lever, and a fourth pulley means operatively connected to said horizontal beam proximate said vertical support; h. cable means having a first end connected to the bottom end of said foot lever and extending through said fourth pulley means, said second pulley means, said third pulley means, back through said second pulley means, through said first pulley means, and having a second end attached to said free weights; i. a digital counter at the top of said vertical beam and connected to the top end of said foot lever.
Claim 2
Dependent Claim 307 words
An aerobic exercising machine that works all the major body muscles simultaneously comprising: a. a vertical beam having a cross arm at the foot end and a forward extension at the top end, said forward extension supporting a plurality of free weights; b. a horizontal beam pivotally connected to said vertical beam by a plate means at approximately one third the height of said vertical beam; c. a rear leg support pivotally connected to said horizontal beam at the end opposite said vertical beam connection; d. an adjustable sloping seat bolted to a seat bracket attached to the horizontal beam above the rear leg support; an adjustable sloping seat connected to said horizontal beam above said rear leg support; e. a foot lever pivotally attached to the top of said vertical beam, the bottom end of said foot lever having a pair of foot pedals, said foot pedals straddling said horizontal beam; f. a vertical support connected to said horizontal beam directly forward of said seat, said vertical support having a hand lever pivotally attached thereto, the upper end of said hand lever having a pair of handgrips; g. a first pulley means operatively connected to said forward extension, a second pulley means operatively connected to said plate means, a third pulley means operatively connected to said hand lever, and a fourth pulley means operatively connected to said horizontal beam proximate said vertical support; h. cable means having a first end connected to the bottom end of said foot lever and extending through said fourth pulley means, said second pulley means, said third pulley means, back through said second pulley means, through said first pulley means, and having a second end attached to said free weights; i. a digital counter at the top of said vertical beam and connected to the top end of said foot lever.
Claim 3
Dependent Claim 27 words
An aerobic exercising machine according to claim 1 wherein said hand lever is made of a telescoping tube in order to lengthen or shorten the arm reach.
Claim 4
Dependent Claim 42 words
An aerobic exercising machine according to claim 2 where said hand lever has several connecting positions for said third pulley means enabling a variation in the swing of the hand lever and also a variation of the effort imposed on the user.
Claim 5
Dependent Claim 30 words
An aerobic exercising machine according to claim 1 where said cable means includes a flat belt between said first and second cable means, and said first pulley means includes spools.
Claim 6
Dependent Claim 40 words
An aerobic exercising machine according to claim 1 where said third pulley means is operatively connected to said hand lever by a turnbuckle, said turnbuckle enabling the tension on said cable to be equalized with that of said foot lever.
Claim 7
Dependent Claim 25 words
An aerobic exercising machine according to claim 1 where part of the free weights include half disks to facilitate easy changing of the total weight.
