A patent for a rowing machine with resistance mechanism
A recently granted patent (Publication Number: US11724152B2) describes a stationary exercise machine with a unique four-bar linkage system. The machine includes a frame, a shaft driven by user force, and a resistance mechanism to resist rotation of the shaft. The four-bar linkage connects a driven member to the shaft, transmitting the user force.
The machine also features a handle at the end of the driven member and a seat that moves along a rail supported by the frame. The four-bar linkage is configured in a way that none of its links are capable of a full revolution.
Additionally, the patent describes a rowing machine variation of the exercise machine. This rowing machine includes a rigid member that pivots about a first pivot axis and a rowing engine with an input shaft, a flywheel for resistance, and a two-stage gearing assembly to increase rotational speed. The transmission assembly converts the pivotal movement of the rigid member to rotational movement of the input shaft using a four-bar linkage.
The patent also mentions that the four-bar linkage can be a pair of linkages positioned on opposite sides of the frame, allowing independent movement. The two-stage gearing assembly includes two disks located on opposite sides of the frame, with the second disk connected to the output shaft. The output shaft is positioned between the input shaft and a second shaft, which is located higher elevationally.
Overall, this patent presents a stationary exercise machine and a rowing machine variation with a unique four-bar linkage system that efficiently transmits user force to the shaft. The inclusion of a resistance mechanism, handle, and movable seat enhances the user experience. The rowing machine variation adds a rowing engine with a flywheel and a two-stage gearing assembly for increased resistance and speed. The independent movement of the linkages and the positioning of the disks and shafts contribute to the functionality and design of the machines.
