Abstract
The present invention relates generally to rowing machines, and, more particularly, to such rowing machines with internal environments that duplicate actual Olympic-class rowing shells in terms of both dimensions and appearance, and simulate the specific rowing motion and technique that occurs on the water.
Claims44
A rowing machine comprising:
- a sled-rigger assembly comprising at least one extension member, a front end and a rear end defining a longitudinal axis there between, wherein said rear end comprises a first rear end connecting member guide;
- a first oar assembly comprising a first oar member constrained to said sled-rigger assembly via at least one said extension member, so that said first oar member is at least free to rotate with respect to said sled-rigger assembly, wherein said first oar assembly has a first connection portion;
- a first drive winch rotatably mounted to said sled-rigger assembly;
- and
- a first drive connecting member assembly comprising a first drive flexible connecting member having a first connection portion, said first connection portion of said first drive flexible connecting member of said first drive connecting member assembly being mechanically connected to the first connection portion of said first oar member, and wherein said first drive flexible connecting member of said first drive connecting member assembly is operatively engaged with said first rear end connecting member guide, wherein at least a portion of said first drive flexible connecting member is fully circumferentially connected to said first drive winch and is adapted to rotate said first drive winch in a first direction.

A rowing machine comprising:
- an elongated shell;
- a base member adapted to, in operation of said rowing machine, rest on and remain at least substantially fixed with respect to the ground, wherein said elongated shell and base member comprise a shell-base assembly;
- a sled member comprising a front end and a rear end defining a longitudinal axis there between being constrained to said shell-base assembly so that said sled member, in operation of said rowing machine, can move with respect to said shell-base assembly along said longitudinal axis;
- and
- a seat connected to said sled member, wherein said seat is adapted to, in operation of said rowing machine, move along said longitudinal axis with respect to said sled member when said sled member is moving.

A rowing machine comprising:
- a base member adapted to, in operation of the machine, rest on and remain at least substantially fixed with respect to the ground;
- a first rotational member constrained to the base member;
- an elongated shell member comprising an elongated first surface defining a first longitudinal direction, with said elongated shell member being located at least substantially on top of said base member so that said first surface can rotate with respect to said first rotational member along the first longitudinal direction, and with said elongated shell member being constrained so that can move with respect to said base member only along the first longitudinal direction;
- a sled member comprising a front end and a rear end defining a longitudinal axis there between constrained with respect to the elongated shell member so that it can move with respect to said elongated shell member only in a second longitudinal direction;
- and
- a seat connected to said sled member.
