Description

elliptical machine

The invention relates to sports training equipment, especially an elliptical exercise machine.

A kind of sports training equipment that makes the legs form a circular motion trajectory by repeatedly stepping on the pedal on the rotating wheel is called a flywheel machine, and further through the design of the link mechanism between the rotating wheel and the pedal, Sports training equipment that makes the legs form an elliptical-like circular motion trajectory is called an elliptical machine. Compared with a flywheel machine, its motion trajectory is more rounded, so that users can pedal more smoothly.

However, because the motion trajectory of the elliptical machine is not a perfect circle, the two ends of the long axis of the elliptical trajectory form abrupt turning points, so that when the user steps on the pedals to these two positions, the movement is often stuck due to the necessity of rapid rotation. The situation greatly affects the operation experience and also reduces the efficiency of sports training.

In view of this, how to improve the above problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide an elliptical exercise machine, which can improve the shape of the circular motion trajectory formed by stepping on the pedal with the legs, make the motion trajectory more rounded and operate smoothly, and promote the efficiency of exercise training.

Please refer to Figures 1 and 2, which are the elliptical exercise machine provided by the present invention, which includes a base frame 1 standing on the ground, an arcuate frame 2 and a rocker mechanism. The base frame 1 is bent to form a boat shape and has a bottom 11 . The front and rear sides of the bottom 11 stand up respectively to form a front side portion 12 and a rear side portion 13 . The top of the front side portion 12 is provided with a handrail 121 . and a panel 122, and the top of the rear side portion 13 is provided with a seat 131 for the user to sit on.

On top, the arcuate bracket 2 is located between the front side portion 12 and the rear side portion 13 , the bottom end of which is fixedly connected to the bottom portion 11 of the base frame 1 , and the top end is fixedly connected to the front side portion 12 by an upper section 21 . The arcuate bracket 2 and the front side portion 12 are separated by an accommodating space 3, and the accommodating space 3 can be used to accommodate a rotating element, such as a rotating wheel 41; further, the accommodating space 3 can accommodate A resistance element 42 connected with the rotating wheel 41 is arranged to provide resistance to the rotation of the rotating element. A crank 43 protrudes from both sides of the rotating wheel 41 , and driving the crank 43 can drive the rotating wheel 41 to form a cyclic rotation.

A first insertion hole 211 , a second insertion hole 212 and a third insertion hole 213 are respectively provided on both sides of the upper section 21 of the above-mentioned arcuate bracket 2 , wherein the first insertion hole 211 , the second insertion hole 212 and the The third sockets 213 are distributed along the upper section 21 from high to low in sequence. A support column 5 is selectively inserted into one of the sockets, and then protrudes laterally from the upper section 21 .

The rocker mechanism is connected with the crank 43 of the rotating wheel 41 to change the movement track formed when the pedal 621 is stepped on. Specifically, the rocker mechanism includes a pair of upper rockers 61 and a pair of lower rockers 62 , wherein one end of the upper rocker 61 is pivoted on the support column 5 , and the other end is provided with a first pivot portion 611 ; One end of the lower rocker 62 is pivoted on the first pivot portion 611, and the other end is provided with a pedal 621 for the user to step on. The lower rocker 62 is provided with a second pivot portion 622 between the first pivot portion 611 and the pedal 621 , wherein the second pivot portion 622 is pivotally connected to the crank 43 .

The above-mentioned base frame 1 has a considerable length, so that the seat 131 and the pedal 621 are far apart. Accordingly, the present embodiment is defined as a horizontal elliptical exercise machine. With the above structure, the user can sit on the seat 131 and place both feet on the pedal 621. When stepping on the pedal 621, the lower rocker 62 is pushed to pull the crank 43 to drive the rotating wheel 41 to rotate. , thereby forming a circular motion, and the lower rocker 62 simultaneously pulls the upper rocker 61 to make it pivot with the support column 5 as the center. Accordingly, through the mutual traction action of the upper rocker 61, the lower rocker 62 and the crank 43, the circular motion trajectory of the pedal 621 (that is, corresponding to the user's feet) can be formed into a more rounded oval shape, That is to say, the radius of gyration at both ends of the entire track is large, and a sharp turn will not be formed, thereby improving the stuck phenomenon during the pedaling process.

Furthermore, in the present invention, the position of the upper rocker 61 can be changed by changing the position of the support column 5 , so that the movements of the upper rocker 61 and the crank 43 pulled by it also occur. change, and finally cause the cyclic movement trajectory of the pedal 621 to change. For example, as shown in FIG. 3 , when the support column 5 is selected to be inserted into the first insertion hole 211 on the upper section 21 , stepping on the pedal 621 will form a track A. As shown in FIG. 4 , when the support column 5 is selected to be inserted into the second insertion hole 212 on the upper section 21 , a track B will be formed by stepping on the pedal 621 . As shown in FIG. 5 , when the support column 5 is selected to be inserted into the third insertion hole 213 on the upper section 21 , the track C will be formed by stepping on the pedal 621 . The above three trajectories are all rounded oval shapes, which help to improve the stuck phenomenon during the pedaling process, and can be selected and implemented according to the actual use situation.

Figure 6 shows the second embodiment of the present invention. The structure of this embodiment is based on the structure of the aforementioned first embodiment, and changes are formed in the relative positions of the seat 131 and the pedal 621 . To be more specific, in this embodiment, compared with the structure of the first embodiment, the length of the base frame 1 is shorter, so that the seat 131 is closer to the pedal 621 . Accordingly, this embodiment is defined as A vertical elliptical exercise machine for users to perform pedaling training in an upright sitting position.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention, and the replacement of equivalent elements should still belong to the scope of the present invention.

To sum up, those skilled in the art can understand that the present invention can achieve the above-mentioned purpose, and it complies with the provisions of the Patent Law.
