Description

elliptical machine

technical field

The utility model relates to an elliptical machine.

Background technique

Elliptical machines (ellipticals), also known as cross-trainers (cross-trainer, X-trainer), are used to simulate sports such as climbing stairs, walking, or running.

The elliptical machine can combine the advantages of a treadmill and a bicycle to perform a full-body exercise in a standing position. Since both feet are fixed on the elliptical machine at the same time, the left and right feet are stressed for half the time, which can reduce the impact force of the knee joint and reduce the probability of injury.

Most of the existing elliptical machines use the motion of "pulleys" and "orbits" to form a closed elliptical motion track. For example, US Pat. No. 7,316,633 discloses an elliptical machine comprising a pair of sliding parts. The front end of each slider is connected to a crank, and the rear end has a pulley that can slide forward and backward on a slide rail. In addition, a swing unit has a pair of swing arms and a pair of reciprocating elements. The front end of each reciprocating element is pivotally connected to the tail end of a corresponding swing arm, and a step is fixed at the rear end of each reciprocating element. Each reciprocating element is pivotally connected to a corresponding slider. During operation, the front end of the slider moves around the crank in a circular track, and the rear end of the slider moves linearly to and fro, so that the motion track of the step is an ellipse.

In addition, US Pat. No. 8,926,478 previously filed by the applicant discloses an elliptical machine including a base, a pair of leg elliptical mechanisms, and a pair of hand elliptical mechanisms. The front end of the base has a frame with a first central axis and a second central axis. The first central axis and the second central axis are parallel to each other and have a distance therebetween. The left and right sides of the frame each have a revolving assembly whose axis is set on the first central axis, so as to respectively allow the leg elliptical mechanism to revolve relative to the first central axis. The hand elliptical mechanism is respectively located on both sides of the frame, and has a reverse assembly whose axis is set on the second central axis. The rotary assembly and the reverse assembly rotate in opposite squares, and the elliptical mechanism of the hand and the elliptical mechanism of the leg make the user's hand and leg form a closed track that revolves in the same direction.
