The left and the right swing linkage assembly can change the angle between the left and right linkage assembly and the post, the driving assembly can rise or lower the left and right linkage assembly via the trick assembly, so as to change the angle between the left and right linkage assembly and the post, resulting in the left and right pedal assembly being moved and a step distance being determined.

Description

Motion device with adjustable stroke span

This creation relates to a type of exercise device, in particular a motion device that can adjust the span.

Ellipticals, also known as cross-trainers (X-trainers), are used to simulate climbing, walking, or running.

The elliptical machine combines the advantages of a treadmill and a pedal to achieve a full-body movement in a standing position. Since both feet are fixed on the elliptical machine at the same time, the left and right feet are half of the time, which can reduce the impact of the knee joint and reduce the chance of injury.

Elliptical machines typically have pedals for the user to step on. The pedals of the traditional elliptical machine have a fixed trajectory, which makes the use of the elliptical machine less versatile.

Some patents, such as the Taiwan patent M403355 "lifting device for elliptical exercisers", disclose a lifting device for an elliptical exercise machine that can change the trajectory of the pedal. However, the span of the motion trajectory (stroke), that is, the distance between the user's feet during exercise, is still fixed.

Fig. 1 shows another conventional elliptical machine 1 having a stroke span fixed at 20 。. Due to the difference in height, this fixed stroke span cannot be adapted to all users, resulting in a reduced training effect.

The sleeve 355 has an internal thread that is screwed with the screw 353, and the motor 351 can drive the screw 353 to rotate, moving the sleeve 355 along the screw 353 in a direction away from the motor 351 or close to the motor 351.

The shaft 371 of the slide rail group 37 can be disposed at one end of the sleeve 355, and both ends of the shaft 371 are located in the sliding groove 373a of the sliding groove piece 373, and can be moved up and down in the sliding groove 373a. In addition, the two ends of the shaft 371 are respectively fixed to one of the linking pieces 375, the linking piece 375 is located on one side of the sliding piece 373, and the other end of the linking piece 375 is fixed to the horizontal bar 311. When the shaft 371 moves, the link piece 375 moves with the shaft 371.

The two ends of the cross bar 311 are pivotally connected to the left and right swing bar sets 31 at one end of the swing bar 313, and the other end of the swing bar 313 is pivotally mounted on the sliding sleeve 315. One end of the connecting rod 317 is connected to the sliding sleeve 315, and the other end is connected to the pedal group 25 through the supporting portion 235 of the supporting rod 23, or the other end of the connecting rod 317 can be directly connected to the pedal group 25. The first linkage rod 331 is sleeved in the sliding sleeve 315, one end of which is pivotally disposed on the vertical rod 11 , the other end of which is pivotally disposed on the second linkage rod 333 , and the other end of the second linkage rod 333 is fixed to the sliding seat 255 . The fixing portion 251 has a slide rail 2511 on which the slider 255 can move.

Referring to FIG. 3, when the motor 351 drives the screw 353, the sleeve 355 is moved away from the motor 351, and the shaft 371 is pushed to move up along the sliding groove 373a of the chute piece 373, and the interlocking piece 375 is moved upward. The crossbar 311 is raised. Thereby, the sliding sleeve 315 moves upward along the first linkage rod 331 , thereby driving the first linkage rod 331 and the second linkage rod 333 such that the first linkage rod 331 and the second linkage rod 332 face the rear of the movement device The end extension causes the angle θ between the first linkage rod 331 and the upright rod 11 to become larger, and the second linkage rod 333 drives the carriage 255 to move backward along the slide rail 2511.

Referring to FIG. 4, when the motor 351 drives the screw 353, the sleeve 355 is brought close to the motor 351, and the shaft 371 is pulled to move downward along the sliding groove 373a of the chute piece 373, and the interlocking piece 375 is moved downward, so that The crossbar 311 is lowered. Thereby, the sliding sleeve 315 moves downward along the first linkage rod 331 , thereby driving the first linkage rod 331 and the second linkage rod 333 such that the first linkage rod 331 and the second linkage rod 332 face the front end of the movement device The retraction causes the angle θ between the first linkage rod 331 and the vertical direction of the upright rod 11 to become smaller, and the second linkage rod 333 drives the carriage 255 to move forward along the slide rail 2511.

3 and 4 show only the left swing link group 31 and the left linkage rod group 33, and the right swing link group and the right linkage rod group are not shown. In this embodiment, the two ends of the crossbar 311 are respectively pivotally connected to the left/right swinging lever group 31. When the crossbar 311 is raised or lowered, the left/right swinging lever group 31 and the left/right interlocking lever group 33 can be simultaneously driven.

5 and 6 show the left and right swinging lever group 31 and the left/right interlocking lever group 33 simultaneously. As shown in FIG. 5, when the crossbar 311 is raised, the angle θ1 between the left first linkage lever 331a and the upright 11 is increased, and the carriage 255 is moved backward; meanwhile, the right first linkage lever 331b and The angle θ2 between the uprights 11 becomes larger, and the carriage 255 is moved forward, whereby the stroke span is increased, for example, to 24 吋.

As shown in FIG. 6, when the crossbar 311 is lowered, the angle θ1 between the left first linkage lever 331a and the upright 11 becomes smaller, and the carriage 255 is moved forward; meanwhile, the left first linkage lever 331b and The angle θ2 between the uprights 11 becomes smaller, and the carriage 255 is moved backward, whereby the stroke span is reduced, for example, to 18 吋.

Figures 5 and 6 show the maximum and minimum travel spans of the exercise device 2, respectively. However, the position of the sleeve 355 can be adjusted such that the stroke span is between the maximum and minimum values.

Since the left and right swing link group 31 and the left and right linkage rod group 33 are disposed between the upright 11 and the pedal group 25 instead of the crank 21, when the stroke span is changed, the elliptical path of the pedal 25 is in the long axis direction. External expansion or contraction, the user will not raise the footsteps due to the increased elliptical trajectory, which is more ergonomic and suitable for users of different heights.
