Description

Movement device with adjustable travel span

technical field

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 on the knee joint and reduce the chance of injury.

Elliptical machines typically have pedals for the user to step on. The pedals of traditional elliptical machines mostly have fixed motion trajectories, which makes the use of elliptical machines relatively lacking in variability.

Referring to FIG. 3 and FIG. 4 , when the motor 351 drives the screw 353 , the sleeve 355 moves along the screw 353 away from the motor 351 , thereby pushing the lifting frame 311 to lift. Thereby, the pulley seat 315 will move upwards along the first linkage rod 331, thereby driving the first linkage rod 331 and the second linkage rod 333, so that the first linkage rod 331 and the second linkage rod 333 Extending toward the rear end of the elliptical machine, the angle θ between the first linkage rod 331 and the vertical direction of the front fixed frame 11 becomes larger, and the second linkage rod 333 drives the sliding seat 255 to move backward along the slide rail 2511 , as indicated by the arrow in the figure.

Referring to FIG. 5 , when the motor 351 drives the screw rod 353 , the sleeve 355 moves along the screw rod 353 towards the motor 351 , thereby pulling the lifting frame 311 to lower it. Thereby, the pulley seat 315 will move down along the first linkage rod 331, thereby driving the first linkage rod 331 and the second linkage rod 333, so that the first linkage rod 331 and the second linkage rod 333 Retracting toward the front end of the elliptical machine causes the angle θ between the first linkage rod 331 and the vertical direction of the front fixed frame 11 to become smaller, and the second linkage rod 333 drives the sliding seat 255 to move forward along the slide rail 2511 .

As shown in Figure 7, when the lifting frame 311 is lifted, the included angle θ1 between the left first linkage rod 331a and the vertical direction of the front fixed frame 11 becomes larger, and drives the sliding seat 255a (together with the pedal) to move forward; at the same time, the angle θ2 between the right first linkage rod 331b and the front fixed frame 11 becomes larger, and drives the slide seat 255 to move backward, thereby, the stroke span is increased, for example, increased to 6.096 cm.

As shown in Figure 8, when the lifting frame 311 is lowered, the angle θ1 between the left first linkage rod 331a and the vertical direction of the front fixed frame 11 becomes smaller, and drives the sliding seat 255a to move backward; at the same time, the right The included angle θ2 between the first linkage rod 331b and the front fixed frame 11 becomes smaller, and drives the sliding seat 255 to move forward, whereby the travel span is reduced, for example, to 4.572cm.

Figures 7 and 8 show the maximum and minimum travel spans of the movement device 2, respectively. However, the position of the sleeve 355 can be adjusted so that the travel span is between the maximum value and the minimum value.

Since the left and right rocking rod groups 31 and the left and right linkage rod groups 33 are arranged between the front fixed frame 11 and the pedal group 25 instead of being connected to the crank 21, when changing the travel span, the ellipse of the pedal 253 The track expands or shrinks in the direction of the long axis, and users will not raise their feet due to the increased travel of the elliptical track, which is more ergonomic and suitable for users of various heights.
