Abstract
An elliptical machine has a frame and an operating linkage between the frame and foot supports. Each side of the operating linkage comprises five links that are connected with five pin joints. A foot support is connected to each side of the operating linkage with each of the five pin joints being positioned forward of the foot support.
Claims21
An elliptical exercise machine comprising a generally stationary frame assembly, a operating linkage supported by said frame assembly, said frame assembly comprising at least one rearmost upright, said operating linkage connected to a first foot support and a second foot support, said first and second foot supports each adapted to receive a user's foot, said operating linkage comprising a first side and a second side, said first side comprising four moving links connected by three pin joints and said second side comprising four moving links connected by three pin joints, each of said three pin joints on said first side being positioned forward of said first foot support and each of said three pin joints on said second side being positioned forward of said second foot support, each of said first and second foot supports moving through a generally elliptical foot trace during operation of said machine and said foot trace being located rearward of said rearmost upright.
An elliptical exercise machine comprising a generally stationary frame assembly, an operating linkage supported by said frame assembly, said operating linkage comprising a left subassembly and a right subassembly, said left subassembly comprising a first geared five bar mechanism and said right subassembly comprising a second geared five bar mechanism.
An elliptical exercise machine comprising a generally stationary frame assembly, a first crank rotationally coupled to said frame assembly, said first crank having a second end rotatable about a first rotational axis that extends through a first end of said first crank, said second end of said first crank rotationally connected to a first end of a first coupler link, a second crank rotationally coupled to said frame assembly, said second crank having a second end rotatable about a second rotational axis that extends through a first end of said second crank, said second end of said second crank rotationally connected to a first end of a second coupler link, a second end of said second coupler link being connected to said first coupler link, a foot support being supported by said first coupler link and said first and second cranks being synchronized together.
An elliptical exercise machine comprising a generally stationary frame assembly, an operating linkage supported by said frame assembly, said operating linkage comprising a left subassembly and a right subassembly, each of said left subassembly and said right subassembly comprising a five bar mechanism and means for controlling a path of movement of at least one pin joint of said five bar mechanism.
