(a) Field of the Invention
The present invention is related to a fitness treadmill, particularly a fitness treadmill structure design with special dual rail and stepping board structure.
(b) Description of the Prior Art
The structural features of conventional treadmill is to install two pieces of movable stepping boards on the machine, allowing user to perform exercises similar to running and jogging while avoiding the vibration caused by impinge and resulting in burden to joints. However, there are several ways to drive the direction, height, or angle of the stepping boards. Some install weight distribution wheel at chosen place, and linking cranks are installed on both sides of the weight distribution wheel. The stepping boards are then connected to the cranks and hence could cause feet exercise alternatively. Others install a bobbing rod on both sides of the erecting pole of the machine. The stepping boards are respectively pivoted at the bottom of the bobbing pole. Hence when stepping on the stepping boards the legs could exercise due to the swinging motion. Still there is a treadmill install a curved single rail before assembling the stepping boards on the rail presenting sliding motion so that user could step on it and exercises.
The above mentioned many treadmills of different kinds of structures. Their common problem is in that user cannot perform running exercise, particularly the sing curved rail and the swinging exercise structures that can only allow user to swing the leg. The muscles on the feet and legs could not exert force and therefore hard to achieve the effect of real exercise. Whereas the treadmill installed with weight distribution wheel has complicated structure that is not only difficult to store away but also costs dearly.
SUMMARY OF THE INVENTIONThe purpose of the present invention is to provide a fitness treadmill that makes use the upper rail, lower rail, and stepping board assembled to the upper and lower rails design so as to allow stepping board perform to and fro rail with action similar to running in order to achieve the result of really exercising both feet as well as avoiding the sport injury of knee burden. And with the upper and lower rails design it is possible to alter the shape of the rails as desired to achieve different exercise result.
The secondary purpose of the present invention is to provide a fitness treadmill design that is installed with two handrails for user to hold on and keep the body balanced. The two said handrails are connected to the two sides of the base; each handrail is installed with a holding section for holding purpose, and a lateral bar is connected in between the two handrails.
The other purpose of the present invention is to provide a fitness treadmill design that could install two rocking rods on the treadmill. The two said rocking rods are long rods that are pivoted at selected places on the lateral bar between the two handrails. A pulling strip is installed at the bottom of each rocking rod so that one end of the pulling strip is pivoted to the rocking rod and the other end is pivoted to the stepping board. In other words, the two rocking rods and the two stepping boards are jointly connected so that when the hands are holding the rocking rods the effect of swinging both arms while running can be achieved.

With the above structural characteristic design of base 1, sliding rail set 2, stepping board 3, handrail 4, and rocking pole stated above, particularly the structure of the said two sliding rail set 2 and stepping board, the fitness treadmill of the present invention is created, allowing user to engage in the indoor running exercise. As the sole of the foot palm is always in contact with the stepping board 3 when using the present invention, unlike the conventional treadmill where the foot might knock against the track, therefore the burden of the knee and ankle joint could be avoided and the sport injury can be prevented. In particular, each sliding rail 21 of the two sliding rail set 2 of the present invention consists of an upper rail strip 211 and a lower rail strip 212. Therefore, the design of the present invention is not only in the light and simple structure and relatively more economic in manufacturing cost but also in bent-knee stepping exercise that could further manifest the performance of fitness exercise. More over, as the rocking pole of the present invention can be pivoted to the lateral bar 44 and the lateral bar 44 can be connected to handrail. The said handrail 4 adopts the method of pivot connection to the front base 11 close to the bottom, hence after loosening of fast rotating fixture 43 the two handrail 4 and the two rocking pole 5 could be folded back (as shown in
In addition, the characteristic of the present invention is in that the structure of the said two sliding rail set 2 and the structure of stepping board 3 and assembly style design. However, the embodiment is not limited to the above examples and could also change its shape according to the need of the exercise, etc. As shown in
