1. Field of the Invention
The present invention relates to an exercise rowboat with a fan, and more particularly to a structure having an elastic rope being reeled around a driving wheel and at least a supporting portion. When a user pulls or releases a stretching device, an effect of exercising can thus be obtained. The elements required for assembling can be reduced thereby to reduce cost and space for storing. The present invention is applicable to use as an indoor exercise rowboat training apparatus for exercising.
2. Description of the Prior Art
Referring to
When a user pulls a handle, a pulling rope “a13” on the rope pulley “a1” can be pulled to render the fly wheel “a4” to generate wind resistance; while the elastic restoration of the expansion band “a10” as well as transmission of various members can restore the changing wheel “a11” to its original position. The above stated structure can only obtain its expected effect by combination of a plurality of pulleys and belt pulleys; because of too many members in assembling, not only the cost of manufacturing is increased, the volume after assembling is increased, but also the rate of damage in use is largely increased.
In view of this and to get rid of the above stated defects, the inventor of the present invention developed the structure of the present invention based on his experience of years and nonstop study and improvement, to make the elements required for assembling reduced, and also make the cost and space for storing reduced.
The primary objective of the present invention is to provide a exercise rowboat with a fan having a function to store energy and to release the energy with a winding elastic rope; the elements required for assembling the exercise rowboat can be reduced, thereby cost can be reduced, and space for storing can be reduced too.
The secondary objective of present invention to provide an exercise rowboat with a fan having a function to control the rotational resistance of the fan by providing a resistance adjusting device, thus a user can obtain effects of different exercising.
Therefore, in order to achieve the above stated objectives, the exercise rowboat with a fan of the present invention is comprised mainly of a supporting skeleton having thereon a slidable seat and two foot pedals respectively for seating and placing of feet of a user; the supporting skeleton is provided on its front end with a fan rotatable in one way and a stretching device able to make the fan rotate. The main technical point of the present invention is resided in that: the front end of the supporting skeleton is provided with a fixing mounting having thereon at least a supporting portion and a driving wheel connecting axially with the fan, an elastic rope is reeled around the driving wheel and the supporting portion, and one end of the elastic rope is connected with the driving wheel while the other end is fixed on the fixing mounting.
When the user pulls a stretching device, the elastic rope is reeled to be in the state of storing energy; when the user stop exerting force, the elastic rope releases the energy to restore the stretching device to its original position.
The fixing mounting and the driving wheel provided in the present invention have therebetween a resistance adjusting device, the device includes a rotary member and a braking member on the outer periphery of the driving wheel, the rotary member is connected with the fan axially to rotate synchronically with the fan. By the friction between the elastically adjusted braking member and the rotary member, different effects of exercising can be obtained in pursuance of different individual requirements.
The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

The stretching device 4 includes a woven belt 41 and a handle 42 connected with one end of the woven belt 41. The fixing mounting 5 has two sets of pulleys (or can be cylindrical rods), the pulleys function as supporting portions 51. The fixing mounting 5 is provided thereon with a driving wheel 6 and a resistance adjusting device 7; the driving wheel 6 is composed of a larger roller 61 and a smaller roller 62 coaxial with each other. The larger roller 61 allows the woven belt 41 of the stretching device 4 to be reeled around its outer periphery, while the smaller roller 62 and the supporting portions 51 allows an elastic rope 8 to be reeled around their outer surfaces, one end of the elastic rope 8 is connected with the smaller roller 62 of the driving wheel 6 while the other end is fixed on the fixing mounting 5.
The resistance adjusting device 7 includes a rotary member 71 and a braking member 72; the rotary member 71 is a roller and is connected with the fan 3 and the driving wheel 6 axially. The braking member 72 is a woven belt contacting with the outer periphery of the rotary member 71. One end of the braking member 72 is fixed on the fixing mounting 5; while the other end is connected with a spring 73, the spring 73 is connected with a control line 74, and is controlled by an adjusting button 75 provided above and on the front end of the supporting skeleton 2 in order to increase or decrease the friction force between the rotary member 71 and the braking member 72; thereby resistances of various amounts can be formed to obtain different effects of exercising in pursuance of different individual requirements.

Accordingly, the present invention has the following advantages:
1. By the elastic nature of the elastic rope, the present invention can render the elements required for assembling reduced, thereby cost can be reduced, and space for storing can be reduced too.
2. The present invention renders the elements required for assembling largely reduced, the rate of damage in use is effectively decreased, and the cost of maintenance can be reduced.
3. The present invention has a resistance adjusting device to control the rotational resistance of the fan; it can afford different requirements of different users to thereby achieve the effect of different exercising.
According to the above disclosed, the present invention can surely achieved the expected objects to provide an exercise rowboat with a fan, the exercise rowboat renders the elements required for assembling reduced, the cost of assembling an be reduced, and space for storing can be effectively reduced too. The present invention is extremely industrially valuable.
