Problems solved by technology

One of the drawbacks of the above-mentioned conventional rowing machine lies in that the resistance device cannot provide a uniform resistance force to the user during the drive phase of the rowing stroke due to the grounds that the winding body, which is formed by the long blet that is wrapped around the shaft for several windings, will gradually decrease in its diameter during...

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.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates generally to exercise apparatus, and more particularly, to a rowing exercise machine.2. Description of the Related Art[0002]The conventional rowing machines employ a handle connected with a long belt wrapping around the shaft of a resistance device for several circumferential windings. When a user pulls the handle backward, the long belt drives the shaft to rotate, thereby providing a desired resistance force against the user. In the recovery phase of the rowing stroke, i.e., in the process that the handle returns to its initial position, the long belt will be rewrapped around the shaft again under an effect of a spring. By preforming the rowing stroke repeatedly, the effect of exercise and fitness can be achieved.[0003]One of the drawbacks of the above-mentioned conventional rowing machine lies in that the resistance device cannot provide a uniform resistance force to the user during the drive p...
