Description

Elliptical machine with improved pedal structure

The invention relates to the technical field of sports equipment, in particular to an elliptical machine with an improved pedal structure.

Please refer to FIG. 1, the main structure of the elliptical machine on the market includes: a base 11, a drag wheel 12 and two transmission rod sets 13, the base 11 can be fixed on the ground, and the drag wheel 12 is pivotally mounted on the base 11 Two, the transmission rod group 13 respectively has a foot rod 131 and a grip rod 132, one end of the foot rod 131 is pivotally arranged on the periphery of the drag wheel 12, the other end of the foot rod 131 is fixed Telescopic rope 14, when the drag wheel 12 rotates, the foot lever 131 will swing around the circumference with the drag wheel 12, and one end of the grip lever 132 is pivotally connected to the foot lever 131 close to the drag wheel At one end of 12, when the foot lever 131 swings with the drag wheel 12, the grip lever 132 also swings, and the user can step on the foot lever 131 and hold the grip lever 132 To simulate hiking or brisk walking.

However, the foot lever 131 of the aforementioned elliptical machine only swings along the circumferential direction of the wind resistance wheel 12 with the rotation of the wind resistance wheel 12, and the angle that the user steps on the foot lever 131 is like stepping on a flat surface. When exercising or walking briskly, a person's ankle will rotate at different angles with different actions such as stepping on the ground, leaving the ground, or approaching the ground. The pedal bar 131 of the general elliptical machine will only follow the wind resistance wheel 12 Swings, the user ankles on his upper ankle will not rotate with the action, therefore, The user stepping on the foot lever 131 will only feel that stepping on the undulating plane is far from the motion that simulates real walking or brisk walking.

Secondly, since the combination of the foot lever 131 and the stepping member is generally L-shaped, the user stands on the foot lever 131, and the hand holds the holding lever 132, so that the user's center of gravity falls on the foot lever On the 131, in real hiking or brisk walking, the human body will lean forward slightly, causing the center of gravity of the human body to deflect forward. Therefore, its design also makes the center of gravity of the human body very different from the center of gravity of the human body during real hiking or brisk walking.

It can be known from the foregoing that elliptical machines on the market have the following disadvantages:
