Description

Motion device with elliptical motion trajectory

The present invention relates to a motion device, and more particularly to a motion device that can provide an elliptical motion trajectory.

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 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 half of each 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.

Taiwan patent, certificate number M403355, entitled "Lifting machine for elliptical exercise machine", discloses a lifting device for an elliptical exercise machine that can change the trajectory of the pedal. As shown in FIG. 1, the lift device 40 includes an electric motor adjustment mechanism 403 including a motor 4031, a screw 4032, and a screw sleeve 4033. The motor 4031 can rotate the screw 4032 to displace the screw sleeve 4033 in a direction away from the motor 4031. The linkage rod 4051 of the lifting device 405 receives the pushing force of the screw sleeve 4033, causing the roller 413 to slide along the ground, and the rail frame 402 above the frame 401 is rotated by the two lugs 4021, so that the rail frame 402 and the ground An angle is formed, thereby changing the trajectory of the pedal. The entire specification of the above-identified patents is hereby incorporated by reference in its entirety in its entirety.

Claims (13)

An exercise device includes: an interactive motion mechanism for a user to operate between a first position and a second position, the interactive motion mechanism having a front half and a rear half; and an angle adjustment mechanism interacting therewith a movement mechanism is connected, the angle adjustment mechanism changes at least one of a movement path, the first position, and the second position of the interaction movement mechanism, the angle adjustment mechanism comprises: a frame body connected to the interaction movement mechanism The front half has a front half and a rear half supported by a supporting surface; a rail frame movably connecting the front half of the interactive moving mechanism, the rail frame having a rear half pivotally connected to the frame In the rear half, the rail frame has a rear half supported by the support surface; a driving member connecting the frame body, Driving a top member to cause the rear half of the frame to rise or fall between a first height and a second height, wherein a movement of the rear half of the frame causes the rail frame to be between the first The inclination angle of the guide rail is inclined with respect to a guide rail at an inclination angle of the second guide rail. The motion device of claim 1, wherein the interactive motion mechanism comprises: a flywheel providing a damping effect; a pulley driving the flywheel; and two cranks respectively located on opposite sides of the pulley to drive the pulley; The support rod has two ends, one end of which is connected to the crank, and the other end is connected to a roller; the roller is disposed on the rail frame. The motion device of claim 1, wherein the interactive motion mechanism provides an elliptical motion path between the first position and the second position and is operable by a two-legged movement. The exercise device of claim 1, wherein the frame is pivotable relative to the support surface, the pivot point of which is adjacent to the front half of the frame and adjacent to the support surface. The motion device of claim 1, wherein the rail frame comprises two rails, and the two first members of the interaction mechanism move on the two rails, wherein the rear half of each of the first members is movable Connected to one of the two rails. The exercise device of claim 1, wherein the support surface is a ground. The motion device of claim 1, wherein the rail frame is pivotable relative to the support surface, the pivot point of which is adjacent to the rear half of the rail frame and adjacent to the support surface. The exercise device of claim 1, wherein at least the front half of the frame and the rear half of the rail frame are in contact with the ground. The motion device of claim 1, wherein the frame rotates counterclockwise with its front end as an axis, and the rail frame rotates clockwise with its rear end as an axis to increase the inclination angle of the guide rail, thereby causing the support to be located at the support. a first body tilt angle between the surface and the frame, the rail tilt angle being between the first rail tilt angle and the second rail tilt angle. The motion device of claim 1, wherein the driving member comprises a motor, a screw, and a screw sleeve connecting the screw, the abutting member is coupled to the screw sleeve, and the motor drives the screw to cause the screw sleeve to follow The screw moves. The exercise device of claim 1, wherein the abutting member is pivotally connected to the frame body and has a first portion and a second portion, the first portion being supported by the support surface, the second portion being transmitted through the screw The sleeve is driven by the motor, the movement of the screw sleeve causing the first portion to move forward on the support surface to increase the inclination angle of the rail, or to move backward to reduce the inclination angle of the rail. The motion device of claim 1, wherein the rear half of the frame is pivotally connected to the front half of the rail frame at two parallel pivot points. The motion device of claim 1, wherein the front end of the frame further comprises at least two foot pads, each of the pads having a side and a circular contact, the face being engaged with the support surface, the circle The junction is engaged with an arcuate joint of the frame.
