Description

Motion device with adjustable stroke span

Technical field

The present invention relates to a motion device, and more particularly to a motion device that can adjust a stroke span.

Background technique

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 bicycle to perform a systemic exercise in a standing position. Since both feet are fixed on the elliptical machine at the same time, the left and right feet are forced to take half of the time, which can reduce the impact force 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 feet of the user during exercise, is still fixed.

Figure 6 is a partially enlarged view showing the pulley block 315 in accordance with a preferred embodiment of the present invention. As previously mentioned, the pulley block 315 is a hollow structure, the first linkage rod 331 passes through the pulley block 315, and the first connecting rod 317 is fixed to the pulley block 315. In addition, the pulley seat 315 can have a plurality of pulleys to abut the first linkage The rod 331 allows the pulley block 315 to slide smoothly along the first linkage rod 331 without gaps. For example, in the present embodiment, the pulley base 315 has a first pulley 3151 and a second pulley 3153; one end of the first connecting rod 317 is pivotally connected to the fastener 3172, and the fastener 3172 has a third pulley 3174, wherein the first pulley 3151 and the first pulley The two pulleys 3153 are located on the same side inside the pulley block 315, and the third pulley 3174 is located between the other side of the pulley block 315 and the first connecting rod 317 such that the rocking bar 313 is clamped by the three pulleys. In other embodiments of the present invention, the number of pulleys is not limited to three, and the position thereof may be appropriately changed. The structure of the pulley block 315 can also be appropriately changed, and is not limited to the one shown in the drawing.

Referring to Figures 3 and 4, when the motor 351 drives the screw 353, the sleeve 355 is moved in the direction away from the motor 351 along the screw 353, thereby pushing the lift frame 311 to be raised. Thereby, the pulley seat 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 333 Extending toward the rear end of the elliptical machine, the angle θ between the first linkage rod 331 and the front bracket 11 in the vertical direction is increased, and the second linkage rod 333 drives the carriage 255 to move backward along the slide rail 2511. As shown by the arrow in the figure.

Referring to Fig. 5, when the motor 351 drives the screw 353, the sleeve 355 is moved toward the motor 351 along the screw 353, thereby pulling the lift frame 311 down. Thereby, the pulley seat 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 333 Retracting toward the front end of the elliptical machine causes the angle θ between the vertical direction of the first linkage rod 331 and the front holder 11 to become smaller, and the second linkage rod 333 drives the carriage 255 to move forward along the slide rail 2511.

3 to 5 show only the right swing link group 31 and the right linkage rod group 33, and the left swing link group and the left linkage rod group are not shown. 7 and 8 simultaneously show the left and right swinging lever groups 31 and the left and right interlocking lever groups 33. As shown in FIG. 7, when the lift frame 311 is lifted, the angle θ1 between the left first interlocking lever 331a and the front mounting bracket 11 in the vertical direction becomes larger, and the carriage 255a is driven (along with the fixed on it) The pedal) moves forward; at the same time, the angle θ2 between the right first linkage rod 331b and the front holder 11 becomes larger, and the carriage 255 is moved backward, whereby the stroke span is increased, for example, to 6.096cm.

As shown in FIG. 8, when the lift frame 311 is lowered, the angle θ1 between the left first interlocking lever 331a and the front mounting bracket 11 in the vertical direction becomes smaller, and the sliding carriage 255a is moved backward; meanwhile, right The angle θ2 between the first linkage rod 331b and the front holder 11 becomes smaller, and the carriage 255 is moved forward, whereby the stroke span is reduced, for example, to 4.572 cm.

Figures 7 and 8 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 lever sets 31 and the left and right linkage lever sets 33 are disposed between the front mount 11 and the pedal set 25 instead of the crank 21, when the stroke span is changed, the ellipse of the pedal 253 The trajectory is expanded or retracted in the direction of the long axis. The user does not raise the footstep because of the increased elliptical trajectory. It is ergonomic and suitable for users of different heights.
