Rowing machine

Abstract

A rowing machine includes a base mount with pulleys, a resistance device, a handle, a transmission member, and a resilient member. The resistance device includes a housing, a shaft having an outer shaft section located outside the housing, and an inner shaft section located inside the housing, a plurality of blades mounted to the inner shaft section, and a transmission wheel mounted to the outer shaft section. The transmission member extends from the handle and has an engagement section engaged with the transmission wheel. The resilient member has a first end disposed to the based mount, and a second end connected with the transmission member in a way that the transmission member and the resilient member wrap around the pulleys. As such, the rowing machine can provide uniform resistance and accurately determine the travel distance of the handle that is pulled by a user.

What is claimed is: 
     
         1 . A rowing machine, comprising:
 a base mount disposed with a plurality of pulleys;   a resistance device including a housing, a shaft extending into the housing and having an outer shaft section located outside the housing, and an inner shaft section located inside the housing, a plurality of blades mounted to the inner shaft section, and a transmission wheel mounted to the outer shaft section;   a handle;   a transmission member extending from the handle and having an engagement section engaged with the transmission wheel; and   a resilient member having a first end disposed to the based mount, and a second end connected with the transmission member;   wherein the transmission member and the resilient member combinedly form a continuous member wrapping around the pulleys.   
     
     
         2 . The rowing machine as claimed in  claim 1 , further comprising a one-way bearing disposed between the transmission wheel and the outer shaft section. 
     
     
         3 . The rowing machine as claimed in  claim 1 , wherein the continuous member extends forwardly from the handle to a front side of the base mount, wraps around a first one of the pulleys and extends downwardly to a bottom side of the base mount, wraps around a second one of the pulleys and extends backwardly to a rear side of the base mount, wraps around a third one of the pulleys and extends forwardly to the bottom side of the base mount, wraps around the transmission wheel and extends backwardly to the rear side of the base mount, wraps around a fourth one of the pulleys, extends forwardly to the front side of the base mount and connects the base mount. 
     
     
         4 . The rowing machine as claimed in  claim 3 , wherein the transmission member comprises a belt section connected between the handle and the engagement section. 
     
     
         5 . The rowing machine as claimed in  claim 4 , wherein the belt section of the transmission member is an elongated flat belt. 
     
     
         6 . The rowing machine as claimed in  claim 4 , wherein the belt section of the transmission member extends forwardly from the handle to the front side of the base mount, wraps around the first one of the pulleys and extends downwardly to the bottom side of the base mount, wraps around the second one of the pulleys and extends backwardly to the rear side of the base mount, and wraps around the third one of the pulleys, extends forwardly to the bottom side of the base mount and connects the engagement section, and then the engagement section wraps around the transmission wheel, extends backwardly to the rear side of the base mount and connects the resilient member, and then the resilient member wraps around the fourth one of the pulleys, extends forwardly to the front side of the base mount and connects the base mount. 
     
     
         7 . The rowing machine as claimed in  claim 1 , wherein the engagement section of the transmission member is a chain; the transmission wheel is a sprocket wheel. 
     
     
         8 . The rowing machine as claimed in  claim 1 , wherein the engagement section of the transmission member is a toothed belt; the transmission wheel is a gear. 
     
     
         9 . The rowing machine as claimed in  claim 1 , further comprising a seat disposed on the base mount in a way that the seat is forwardly and backwardly moveable on the base mount. 
     
     
         10 . The rowing machine as claimed in  claim 9 , wherein the resistance device is disposed in front of or behind the seat. 
     
     
         11 . The rowing machine as claimed in  claim 1 , further comprising a foot pedal rack disposed on the base mount. 
     
     
         12 . The rowing machine as claimed in  claim 1 , wherein the outer shaft section of the shaft is located at a bottom side, a top side, a left side or a right side of the housing of the resistance device.
