Abstract
Abstract This invention relates to a body exercising apparatus for execution of a very large number of different exercises. The apparatus comprises a single upright post with a platform extending from one side of the bottom end and having pulley means on the top engaged by a cable of variable effective length. The cable is connected with one end in movement adjustable fashion to a weight carrying lever attached to the post on a side opposite to the platform side whereas the opposite end of the cable is connectable to any one of a plurality of separate devices for engagement by a person on the platform for exercising purposes. Additional pulleys for optional engagement by the cable, rigid bar members and means for locking of the lever are also associated with the post.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
379 words
Apparatus for isotonic and isometric body exercising comprising an elongated flexible element of changeable effective length which is lead over elevated pulley means and connected to weight mounting means by one end and any one of a number of different parts adapted for engagement by the exerciser, and a horizontal platform on which the exercises are performed, including, in combination: a single upright post of changeable height and having a top and and a bottom end of which the bottom end engages a base to which the platform is also attached in a radially extending position; a horizontal beam across the top of the post having tandem arranged pulleys at the ends for said element whereby opposite end portions of the element are at opposite sides of the post; a lever pivotally attached by one end to an intermediate portion of the post in a vertically adjustable fashion and from which it extends in a direction opposite to the direction of extension of the platform whereas a weight is attached to an opposite end portion of the lever; additional pulleys on the post at changeable positions and selectively engageable by the flexible element for the latter to extend outwardly from the post at different selected positions and at different angles; an additional lever device pivotally connected at adjustable positions on the upper intermediate portion of the post on the same side as the platform; a number of separate attachment parts for selective connection to the flexible element and including different bar-like members and a head harness each having a connecting device for ready connection to the end of the flexible element on the platform side of the post; a lockable winch device adjustably and lockably mounted on the said lever at any position between the pivoted end of the lever and the weight whereas the end portion of the flexible element is wound on said winch device whereby the leverage and the effective length of the flexible element is readily and infinitely variable for changing the position of any one of the attachment parts to the flexible element and readily varying the load against which different exercises are isotonically performed; and a means for immovably coupling the lever for isometrically performing exercises with any one of the attachment parts.
Claim 2
Dependent Claim
379 words
Apparatus for isotonic and isometric body exercising comprising an elongated flexible element of changeable effective length which is lead over elevated pulley means and connected to weight mounting means by one end and any one of a number of different parts adapted for engagement by the exerciser, and a horizontal platform on which the exercises are performed, including, in combination: a single upright post of changeable height and having a top and and a bottom end of which the bottom end engages a base to which the platform is also attached in a radially extending position; a horizontal beam across the top of the post having tandem arranged pulleys at the ends for said element whereby opposite end portions of the element are at opposite sides of the post; a lever pivotally attached by one end to an intermediate portion of the post in a vertically adjustable fashion and from which it extends in a direction opposite to the direction of extension of the platform whereas a weight is attached to an opposite end portion of the lever; additional pulleys on the post at changeable positions and selectively engageable by the flexible element for the latter to extend outwardly from the post at different selected positions and at different angles; an additional lever device pivotally connected at adjustable positions on the upper intermediate portion of the post on the same side as the platform; a number of separate attachment parts for selective connection to the flexible element and including different bar-like members and a head harness each having a connecting device for ready connection to the end of the flexible element on the platform side of the post; a lockable winch device adjustably and lockably mounted on the said lever at any position between the pivoted end of the lever and the weight whereas the end portion of the flexible element is wound on said winch device whereby the leverage and the effective length of the flexible element is readily and infinitely variable for changing the position of any one of the attachment parts to the flexible element and readily varying the load against which different exercises are isotonically performed; and a means for immovably coupling the lever for isometrically performing exercises with any one of the attachment parts.
Claim 3
Dependent Claim
98 words
An apparatus for body exercising as claimed in claim 1 wherein the platform comprises a rectangular member pivotally connected by a transverse end to the base element about a horizontal axis and being lockable substantially at right angles to the post by a sloping brace frame having one end connected to the platform and the opposite end to a slidable and lockable part on a lower portion of the post, said platform including a number of rigid coplanar panels of which a center panel is displaceable to and lockable in any one of a number of sloping positions.
Claim 4
Dependent Claim
58 words
An apparatus for body exercising as claimed in claim 1 wherein a horizontally disposed wide U-shaped bar is adjustably fixable in vertical directions on the post for parallel limb portions thereof to extend in the direction of projection of the platform, said bar being provided with downwardly projecting rigid hooks adjacent the end of the parallel limb portions.
Claim 5
Dependent Claim
49 words
An apparatus for body exercising as claimed in claim 1 wherein a tubular part is provided on the platform side portion of the beam across the top of the post projecting horizontally and transverse to said beam, saiD tubular part being adapted to retractably locate a rigid horizontal bar.
Claim 6
Dependent Claim
92 words
An apparatus for body exercising as claimed in claim 1 wherein the additional lever device comprises a substantially Y-shaped rigid part of which the end of the leg portion is pivotally connected to a bracket which in turn is adjustably fixable onto the post whereas arm portions of said part are located in parallel spaced relationship and being provided with inline horizontally and outwardly protruding handle-forming extensions on the ends, said leg portion mounting an adjustable clamp member having a connecting device for disengageable coupling of one end of the flexible element.
Claim 7
Dependent Claim
67 words
An apparatus for body exercising as claimed in claim 1 wherein a separate attachment device for connection to the end of the flexible element at the platform side of the post includes a rigid elongated part having a pair of flexible material loop-forming straps attached to end portions thereof whereas on the center portion a connecting eye device is provided for disconnectible connection to the flexible element.
Claim 8
Dependent Claim
62 words
An apparatus for body exercising as claimed in claim 1 wherein a separate attachment device for connection to the end of the flexible element at the platform side of the post includes a rigid elongated part of which the center portion is of keen V-shape and having a connecting eye device at the apex thereof for disconnectible connection of the flexible element.
Claim 9
Dependent Claim
88 words
An apparatus for body exercising as claimed in claim 1 wherein a rigid elongated part is provided having end portions of V-shape formation which project in the same direction whereas at the center of the part a connecting eye device is provided for disconnectible connection of the flexible element, said eye device being arranged to project in a direction opposite to the direction of projection of the V-shape formations, said formations being in addition provided at the apexes with coupling devices for attachment of a further flexible element.
