Lever assembly 25 is depicted in greater detail inFIGS. 6 , 7 and 8. -
Lever 26 is operatively associated withbracket arms -
Arm 70 includes a proximate end that is mounted on and can pivot about fixed axle 70 (FIG. 8 ) ofcylindrical base 50.Pin 71 is fixedly secured in the distal end ofarm 70 and extends outwardly away from the inside and outside ofarm 70. InFIG. 6 , the portion ofpin 71 extending outwardly away from the inside ofarm 70 bears against an edge ofbracket 56. One end ofelastic member 74 is attached to the portion ofpin 71 that extends outwardly away from the outside ofarm 70 and that also extends away frombracket 56. -
Arm 72 includes a proximate end that is mounted on and can pivot about fixed axle 70 (FIG. 8 ) ofcylindrical base 50.Pin 73 is fixedly secured in the distal end ofarm 72 and extends outwardly away from the inside and outside ofarm 72. InFIG. 6 , the portion ofpin 73 extending outwardly away from the inside ofarm 70 bears against an edge ofbracket 56. One end ofelastic member 74 is attached to the portion ofarm pin 73 that extends outwardly away from the outside of arm 72 (not visible inFIGS. 6 to 8 ) and that also extends away frombracket 56. -
Spherical handle 76 is fixedly secured toorthogonal slide 75 byneck 76A.Neck 76A extends throughslot 77.Handle 76 is utilized to slidably displaceslide 75 between three operative positions.Slide 75 includesdistal end 75A,notch 83, andintermediate portion 75B. - The first operative position of
slide 75 is illustrated inFIGS. 12 and 19 . In the first operative position,distal end 75A is positioned in a notch 80 (or 81) that is formed in the proximate end ofarm 72. Thenotch 83 ofslide 75 spans and extends over and above the distal end ofarm 70 so thatslide 75 does not engagearm 70. Whenslide 75 and handle 76 are in the first operative position, graspinghandle 28 and displacing and pivotingarm 26 in a direction of travel Q (FIG. 6 ) simultaneously pivotsslide 75 in the same direction and causes slide 75 to pivot in the same direction. Whenslide 75 pivots, it causes (becauseslide 75 is engaging notch 80) the proximate end ofarm 72 to pivot aboutcylindrical base 50 in the same direction of travel Q, which causes the distal end ofarm 72 to move away frombracket 56 in the direction of arrow W. When the distal end ofarm 72, and consequently pin 73, moves in the direction of arrow W,elastic member 74 is stretched and pullspin 71 againstbracket 56.Arm 70 andpin 71 do not move becausepin 71 is pulled againstbracket 56 byelastic member 74. -
Handle 76 andneck 76A are fixedly connected to slide 75. InFIG. 14 , the right hand end ofslide 75 is not visible and is slidably mounted in a housing that includeupper panel 77A. An aperture (not visible) is formed in said right hand end and houses a spring (not visible) that upwardly presses a ball bearing (not shown) against the undersurface (not shown) ofupper panel 77A. The undersurface includes three spaced apart detents each shaped to removably receive the ball bearing whenslide 75 is in one of the three operative positions described herein. A similar aperture (not visible) is formed in the left hand end of slide 62 (FIG. 8 ) and receives a spring that upwardly presses a ball bearing 62C (FIG. 8 ) against the undersurface ofupper panel 77B of the housing in which slide 62 slidably moves. The undersurface ofupper panel 77B has, as does the undersurface ofupper panel 77A, three spaced apart detents each shaped to removably receive ball bearing 62C whenslide 62 is in one of its three operative positions. -
Slide 75 is displaced in the direction of arrow K inFIG. 14 by graspinghandle 76 and applying sufficient force in the direction of arrow K to downwardly dislodge the ball bearing from a detent inpanel 77A and allowslide 75 to slide in the direction of arrow K (or in the opposite direction, as the case may be). After the ball bearing is dislodged from the detent, the spring associated with the ball bearing continues to upwardly press the ball bearing against the undersurface ofpanel 77A. Whenslide 75 reaches a new position, the spring pushes the ball bearing into another one of the detents formed in the undersurface ofpanel 77A to receive the ball bearing when theslide 75 is in the new position. In this manner, handle 76 can be utilized to moveslide 75 back and forth between its three operative positions, and at each operative position the ball bearing operatively associated withslide 75 seats in a detent to help stabilize the slide in that operative position.Handle 53 is utilized to slidably displace slide 62 (FIG. 8 ) in a similar manner. - The second operative position of
slide 75 is illustrated inFIGS. 14 and 18 .Slide 75 is moved to the second operative position by graspinghandle 76, pulling it outwardly in the direction of arrow L (FIG. 12 ) to release the spring loaded ball bearing, and by pulling onhandle 76 to displaceslide 75 in the direction of arrow J (FIG. 12 ) to move the slide to the position shown inFIGS. 14 and 15 . Whenslide 75 is in the position illustrated inFIGS. 14 and 15 ,notch 83 spans and extends over and above the proximate ends ofarms lever 26 can be freely moved in the directions indicated by arrows H and Q inFIG. 6 . - The third operative position of
slide 75 is illustrated inFIGS. 16 and 17 . In the third operative position,intermediate portion 75B is positioned in anotch 82 that is formed in the proximate end ofarm 70. Thenotch 83 spans and extends over and above the distal end ofarm 72 so thatslide 75 does not engagearm 72. Whenslide 75 and handle 76 are in the third operative position, graspinghandle 28 and displacing and pivotingarm 26 in a direction of travel H (FIG. 6 ) simultaneously pivotsslide 75 in the same direction and causes slide 75 to pivot in the direction. Whenslide 75 pivots, it causes (becauseslide 75 is engaging notch 82) the proximate end of arm 702 to pivot aboutcylindrical base 50 in the same direction of travel H, which causes the distal end ofarm 70 to move away frombracket 56 in the direction of arrow T (FIG. 6 ). When the distal end ofarm 70, and consequently pin 71, moves in the direction of arrow T,elastic member 74 is stretched and pullspin 73 againstbracket 56.Arm 72 andpin 73 do not move becausepin 73 is pulled byelastic member 74 againstbracket 56. -
Lever 27 is operatively associated withbracket arms - Arm 57 (
FIG. 8 ) includes a proximate end that is connected to and can pivot aboutcylindrical base 50.Pin 58 is fixedly secured in the distal end ofarm 57 and extends outwardly away from the inside and outside ofarm 57.

Whenpin 89 is displaced in the direction of arrow M, the proximate end ofarm 100 pivots pin 102 and the distal end ofarm 100 moves away fromedge 103 ofbracket 105. When the distal end ofarm 100, and consequently pin 89, moves in the direction of arrow M,elastic member 91 is stretched and pullspin 90 againstedge 104 ofbracket 56.Arm 101 and pin 90 do not move becausepin 71 is pulled against fixedbracket 105. This increases the magnitude of the resisting force produced byelastic member 91. Allowinglever 84 to move from the second operative position ofFIG. 22 back to the first operative position ofFIG. 23 reduces the magnitude of the force produced byelastic member 91. - When
lever 84 is in the first operative position ofFIG. 23 , andlever 84 is manually grasped and displaced in the direction of arrow N to the third operative position illustrated inFIG. 24 ,edge 116 ofplate 115 bears against and displacespin 90, and consequentlyarm 101, in the direction of arrow N. Whenpin 90 is displaced in the direction of arrow N, the proximate end ofarm 101 pivots pin 102 and the distal end ofarm 101 moves away fromedge 104 ofbracket 105. When the distal end ofarm 101, and consequently pin 90, moves in the direction of arrow N,elastic member 91 is stretched and pullspin 89 againstedge 103 ofbracket 56.Arm 100 and pin 89 do not move becausepin 89 is pulled againstbracket 105. This increases the magnitude of the resisting force produced byelastic member 91. Allowinglever 84 to move from the third operative position ofFIG. 24 back to the first operative position ofFIG. 23 reduces the magnitude of the force produced byelastic member 91. - The following example is given by way of explanation, and not limitation, of the exercise machine of the invention.
