1. Field
The embodiments of the invention relate to exercise devices or machines, and more particularly relates to elliptical exercise machines having angle-adjusting mechanisms.
2. Description of Related Art
Without limiting the disclosed embodiments, an elliptical trainer, also called a cross-trainer or an X-trainer, is a stationary exercise machine to simulate stair climbing, walking, or running.
The elliptical trainer does not cause excessive pressure to the joints as the two legs simultaneously share the burden, hence decreasing the risk of impact injuries.
The elliptical trainer typically includes two pedals capable of being stepped by a user. For conventional elliptical trainers, the track of the pedals cannot be varied.
Taiwan Patent, Publication No., M403355, entitled “Rising Device for Elliptical Trainers,” discloses an elliptical trainer with a rising device that can adjust the track of the pedals. As shown in
Yet there is still a need for an elliptical trainer that can reduce cost and increase stability and varieties of exercise.
In one general aspect, the present invention relates to exercise devices or machines, and more particularly relates to exercise devices or machines having the angle-adjusting mechanism.
In an embodiment of the present invention, an elliptical trainer is provided with an angle-adjusting chassis and a reciprocal-movement mechanism. The reciprocal-movement mechanism is operable between at least a first position and a second position. The reciprocal-movement mechanism has a front portion and a rear portion. The angle-adjusting chassis couples with the reciprocal-movement mechanism and configured to change a moving path of the reciprocal-movement mechanism. A frame couples with the front portion of the reciprocal-movement mechanism. The frame has a rear portion and a front portion configured to be supported by a supporting surface. The angle-adjusting chassis is configured to change the moving path of the reciprocal-movement mechanism by varying a degree of the front portion of the frame relative to the supporting surface. A guider is movably coupled with the rear portion of the reciprocal-movement mechanism. The guider has a front portion pivotably coupled with the rear portion of the frame and a rear portion supported by the supporting surface. An angle-adjusting assembly couples with the frame for driving an intermediary part that causes the rear portion of the frame to rise or fall between a first level and a second level, a movement of the rear portion of the frame causing an incline angle of the guider to vary between a first guider incline angle and a second guider incline angle.
In another embodiment of the present invention, an exercise device is provided with an angle-adjusting chassis and a reciprocal-movement mechanism capable of being operated by a user. The angle-adjusting chassis comprises a frame, a guider, an intermediary part, an angle-adjusting assembly. The reciprocal-movement mechanism is arranged on the frame. A front portion of the frame is configured to be supported by a supporting surface. A rear portion of the frame movably couples with a front portion of the guider, and a rear portion of the guider is configured to be supported by the supporting surface. The angle-adjusting chassis is configured to change at least one moving path of the reciprocal-movement mechanism by varying a degree of the front portion of the frame relative to the supporting surface. The angle-adjusting assembly couples with the frame for driving a movement of the front portion of the frame to vary the degree of the front portion of the frame relative to the supporting surface.
In another embodiment of the present invention, an elliptical trainer is provided with an angle-adjusting chassis and a reciprocal-movement mechanism capable of being operated by a user. The angle-adjusting chassis comprises a frame, a guider, an intermediary part, an angle-adjusting assembly, and a linkage assembly. The reciprocal-movement mechanism is arranged on the frame, a front end of the frame contacting with a supporting surface. A rear portion of the frame pivotally couples with a front portion of the guider, and a rear end of the guider contacts with the supporting surface. The intermediary part fixes with the guider. The linkage assembly comprises an upper end, a middle pivot, and a lower end, wherein the upper end pivotally connects with the angle-adjusting assembly, the middle pivot pivotally connects with intermediary part, and the lower end is in contact with the supporting surface. When the angle-adjusting assembly pushes the linkage assembly, the guider rotates clockwise around a pivot point near its rear end, and the frame rotates counterclockwise around a pivot point near its front end, resulting in a variation in each of a first angle between the frame and the supporting surface, a second angle between the guider and the supporting surface, and a third angle between the linkage assembly and the supporting surface.
In an embodiment, the reciprocal-movement mechanism comprises a flywheel providing a damping effect, a driving wheel for driving the flywheel, two cranks respectively arranged at a side of the driving wheel for driving the driving wheel, two supporting driving arms with each arm comprising two ends in which one end couples with one of the two cranks and the other end movably couples with the guider.
In an embodiment, the reciprocal-movement mechanism further comprises two handle members, two handle members, two linkage arms, and two pedals. The two handle members movably couples to the angle-adjusting chassis, each of the two handle members having at least one upper end for enabling a user operation by hand. Each linkage arm couples between a lower end of one of the two handle members and a portion one of the two driving arms. The two pedals couples with the linkage arms.
In an embodiment, each of the two pedals is pivotally or adjustably coupled with a corresponding linkage arm of the two linkage arms.
In an embodiment, the reciprocal-movement mechanism provides an elliptical or elliptical-like moving path between the first position and the second position and enables an operation by foot movements.
In an embodiment, the frame is pivotably movable relative to the supporting surface based on a pivot point near the front portion of the frame and near the supporting surface.
In an embodiment, the guider is pivotably movable relative to the supporting surface based on a pivot point near the rear portion of the guider and near the supporting surface.
In an embodiment, at least the front portion of the frame and the rear portion of the guider provide ground support for supporting the exercise device when the exercise device rests on the supporting surface.
In an embodiment, the guider rotates clockwise around a pivot point near the rear portion of the guider to increase the incline angle when the frame rotates counterclockwise around a pivot point near the front portion of the frame, resulting in a first frame incline angle between a bottom of the frame and the supporting surface and the incline angle between the first guider incline angle and the second guider incline angle, with the incline angle being between a bottom of the guider and the supporting surface.
In an embodiment, a rear end of the frame is pivotally attached to and below the front end of the guider.
In an embodiment, the angle-adjusting assembly is attached to the rear portion of the frame.
In an embodiment, the intermediary part is placed near and substantially under a front end of the guider.

As shown in
The rear portion 201R of the frame 201 pivotally couples with the front portion 202F of the guider 202; the connection can be the horizontally connected or connected above or below the guider 202. In this context, the term “the rear portion 201R of the frame 201” refers to the rear end 201B of the frame 201 and the portion near the rear end 201B, and the term “the front portion 202F of the guider 202” refers to the front end 202A of the guider 202 and the portion near the front end 202A.
In this preferred embodiment, the rear end 201B of the frame 201 pivotally attached to and below the guider 202 and near the front end 202A of the guider 202. In another embodiment, the rear end 201B of the frame 201 pivotally connects with the front end 202A of the guider 202.
In this embodiment, the intermediary part 204 fixed with the guider 201, and the angle-adjusting assembly 203 fixes with the frame 201 for driving (ex., pushing or drawing) the intermediary part 204 that cause the front portion of the guider 202 to rise or fall between a first level and a second level, wherein a movement of the front portion of the guider causes an incline angle of the guider to vary between a first guider incline angle and a second guider incline angle. In this embodiment, the angle-adjusting assembly 203 may comprise, but is not limited to, a motor 2031, a screw 2032, and a thread tube 2033. In addition, the intermediary part 24 may pivotally connect with thread tube 2033 via a pivot 204A.
In detail, the motor 2031 can drive the screw 2032 to rotate and to thus make the thread tube 2033 moving in the direction away from the motor 2031, so as to push the intermediary part 204. When the angle-adjusting assembly 203 pushes the intermediary part 204, the guider 202 rotates clockwise around at a pivot point near to its rear end 202B, and the frame 201 rotates counterclockwise around a pivot point near to its front end 201A. As a result, a first θ1 is present between the guider 202 and the supporting surface (e.g., the ground), and a second angle θ2 is present between the frame 201 and the supporting surface.
The intermediary part 204 may be attached above the guider 202 and near the front end 202A of the guider, and the angle-adjusting assembly 203 may be attached to or above the frame 201 and near the rear end 201B of the frame. The same or similar purpose can be achieved when one or two of the above-mentioned components are arranged at other locations. For example, the intermediary part 204 can be coupled at the front end 202A of the guider, or attached near to and substantially under a front end 202A of the guider 202. For example, the angle-adjusting assembly 203 could not be fixed with the frame 201 but fixed with other mechanism for providing a force pushing the intermediary part 204. In an embodiment, a rear end of the frame is pivotally mounted attached to and below the front end of the guider. In an embodiment, the angle-adjusting assembly is attached to the rear portion of the frame. In an embodiment, the intermediary part is placed near and substantially under a front end of the guider. Modification, equivalent, and exchange can be made to the present invention for a person skilled in the art, and those modification, equivalent, and exchange are within the scope of the present invention.
In one embodiment, the frame 201 is pivotably movable relative to the supporting surface based on a pivot point near the front portion of the frame 201 and near the supporting surface. In one embodiment, the guider 202 is pivotably movable relative to the supporting surface based on a pivot point near the rear portion of the guider and near the supporting surface.
As shown in
The above-mentioned operation can be reversible. The motor 2031 can drive the screw 2032 to rotate and to make the thread tube 2033 moving in the direction toward the motor 2031, and hence cause the frame 201 and the guider 202 back to the first position as shown in
The user steps on the pedals 312 with his or her hands holding the stationary handles 303 or the handles 302. Therefore, when the user exerts forces on the handles 302 and pedals 312, the flywheel 309 is driven by the driving wheel 308 via the swing arms 306, the linkage bars 310, the driving arms 311, and the cranks 307, and the wheel 313 reciprocates on the guider 202, and the pedals 312 makes an elliptical or an elliptical-like circle, respectively. The user can control the angle-adjusting assembly 203, e.g., motor, via the control panel 301, so as to control the first angle θ1 and the second angle θ2. The degree of the first angle θ1 and the second angle θ2 can be varied. For example, the slope of the frame 201 and the guider 202, can be slightly adjusted between the first angle θ1 and the second angle θ2, as respectively shown in
It should be noted that the position of the intermediary part 204 affects the first angle θ1. The nearer the intermediary part 204 approaches to the rear end 202B, the smaller the first angle θ1 is, and vice versa. Similarly, the rear end 202B of the frame 201 is preferably the pivot point, and the nearer the pivot point approaches to the rear end 202B, the smaller the second angle θ2 is, and vice versa. In other embodiments of the present invention, the position of the intermediary part 204 and the pivot point can be other locations, so as to alter the first angle θ1 and the second angle θ2.
As shown in
In addition, the inner tube 2034 can be retracted to the outer tube 2034 via the manual or automatic control device, so that the frame 201 and the guider 202 can restore to the position as shown in
Referring to
The linkage assembly 205 comprises an upper end 205A, a middle pivot 205B, and a lower end 205C. The intermediary part 204 is fixed with the guider 202, the upper end 205A pivotally connects with the thread tube 2033, the middle pivot 205B pivotally connects with intermediary part 204, and the lower end 205C is in contact with the supporting surface or the ground.
As shown in
Accordingly, embodiments of the present invention provide exercise devices in which the frame and the guider respectively rotate about an end, so as to alter and control a degree of the front portion of the frame relative to the supporting surface, i.e., θ1, and thus change the moving path of the reciprocal-movement mechanism. The frame and guider of conventional trainers are overlapped with each other. By contrast, the dimension of the frame is significantly reduced and the frame not overlaps with the guider; therefore the material cost can be saved. Further, the frame of conventional trainers needs to be horizontally arranged and attached to the ground, while the frame of the present invention has a novel design without those limitations. In addition, because the pivot point of the angle-adjustment chassis is near to the center of the elliptical trainer, the response time of the angle adjustment of this invention is faster than that of the prior art.
