Abstract
An exercise arm assembly for mounting on an exercise machine frame has a main arm, a swing arm, and a handle. The main arm has a first end for pivoting on a frame of the machine to pivot about a first pivot axis. The swing arm has a first end pivoted to the second end of the main arm for pivoting about a second pivot axis. The handle is pivoted to the swing arm for pivoting about a third pivot axis, with each pivot axis being perpendicular to the other two pivot axes to form a perpendicular, tri-pivot arm system.
Claims46
An exercise arm assembly, comprising:
- a main arm having a first end for pivoting on a frame of an exercise machine for pivoting about a first pivot axis;
- a swing arm having a first end pivoted to the main arm for pivoting about a second pivot axis;
- and
- a handle pivoted to the swing arm for pivoting about a third pivot axis, each pivot axis being perpendicular to the other two pivot axes.
An exercise arm apparatus, comprising:
- a pair of exercise arm assemblies;
- each arm assembly having a main arm, a swing arm, and a handle;
- each main arm having a first end for pivoting on a frame of an exercise machine for pivoting about a first pivot axis and a second end;
- each swing arm having a first end pivoted to second end of the respective main arm for pivoting about a second pivot axis;
- and
- each handle being pivoted to the respective swing arm for pivoting about a third pivot axis, each pivot axis being perpendicular to the other two pivot axes.
An exercise machine, comprising:
- a support frame having a base, an upright portion extending upwardly from the base and having an upper end, and an upper support extending transversely from the upper end of the upright portion;
- a seat supported on the frame;
- a pair of exercise arm assemblies pivotally secured to the frame to extend on opposite sides of said seat;
- each arm assembly having a main arm, a swing arm, and a handle;
- each main arm having a first end pivoted to the frame for pivoting about
- a first pivot axis and a second end;
- each swing arm having a first end pivoted to second end of the respective main arm for pivoting about a second pivot axis;
- and
- each handle being pivoted to the respective swing arm for pivoting about a third pivot axis, each pivot axis being perpendicular to the other two pivot axes.
An exercise arm apparatus, comprising:
- a main arm having a first end linked to an exercise resistance and a second end;
- a swing arm having a first end pivoted to the second end of said main arm for pivoting about a pivot axis and a second end;
- a handle at the second end of said swing arm;
- a pivot connection between the second end of said main arm and the first end of said swing arm, the pivot connection comprising a pivot bracket secured to the end of one of the arms and having a base plate secured to said arm and pair of spaced end plates projecting from said base plate over the end of the other arm, a sleeve secured to the end of the other arm and extending co-axially with said pivot axis, and a pivot pin extending between the end plates along said pivot axis and rotatably engaged in said sleeve;
- and
- a range limiting device for limiting the swing of the swing arm about the second pivot axis to a predetermined angular range, the range limiting device being mounted between said end plates and within an area enclosed by said pivot bracket;
- the range limiting device comprising a first part secured to said sleeve and having a notch facing said base plate and extending in an arc about said pivot axis, the notch being of predetermined length and having opposite ends located within said area enclosed by said pivot bracket, and a second part comprising a pin extending between said end plates parallel to said pivot axis and engaging in said notch.
