As shown in FIGS. 1-3 , the elliptical exercise machine 1 includes a frame body 10 for placing on the ground and defining a front end, a rear end, a left side and a right side according to the direction of the user's operation. The frame body 10 includes a base 11 , a mounting frame 12 , a pole 13 and a rail seat 14 . The setting frame 12 is fixedly connected to the front end of the base 11 , the upright rod 13 is arranged on the setting frame 12 and extends upward, and a console 15 is arranged on the top. The guide rail base 14 has a front end and a rear end, the front end is connected to the base 11 , the rear end extends backward relative to the base 11 , and two long guide rails 16 are formed on the top surface of the guide rail base 14 .

A belt pulley 21 and a flywheel 22 are respectively pivoted on the setting frame 12 in the left and right axial directions, and can rotate in situ, and the two are mutually driven by a belt. The two crank frames 23 are fixedly connected to both sides of the pulley 21 respectively. The crank frames 23 are in the shape of a cross, and each is provided with a wrapping contact 231 . The left and right wrapping contacts 231 are in a relative relationship of 180 degrees.

The two connecting rods 24 are located on the left and right sides of the frame body 10, and each has a front end, a rear end, a pivot joint 241 located behind the middle, and a connection between the rear end and the pivot joint 241. Section 242. The front ends are respectively pivotally connected to the rewinding joints 231 , and the rear ends are each pivotally provided with a roller 243 , which can move between the front and rear ends of the guide rail 16 of the guide rail seat 14 .

The two armrest bars 25 are pivotally arranged on the left and right sides of the vertical bar 13 in the left and right axial directions, and can swing back and forth. Each handrail bar 25 has a top end and a bottom end, and the top end can be grasped by the user when exercising.

Two support rods 26 are located on the left and right sides of the frame body 10, each with a front end and a rear end, the front end is pivotally arranged at the bottom end of the handrail rod 25, and the rear end extends backward for an appropriate length, and is at a position behind the middle. The pivot portion 241 is pivotally connected to the corresponding connecting rod 24 by a pivot.

The two support bases 30 are respectively arranged on the left and right support rods 26 and are located behind the pivot joint 241. A guiding mechanism 20 can guide each supporting seat 30 to move along a closed track respectively. The top surface of the support base 30 is provided with left and right direction sliding rails 31 , and each side edge is provided with a notch 32 . Each support base 30 is respectively provided with a pedal 40, and a connecting piece 41 is fixedly arranged below each pedal 40, and a plurality of rollers 42 corresponding to the slide rails 31 of the support base 30 are pivoted below the connecting piece 41, so that the pedal 40 can pass through the roller 42. It rotates in the slide rail 31 and moves left and right relative to the support seat 30 between an inner position and an outer position. In addition, at the place corresponding to the notch 32 of the supporting base 30 , the connecting piece 41 has a connecting portion 411 extending downward.

A linkage mechanism is connected to the pedal 40. In the present embodiment, the linkage mechanism is two rod-shaped connectors 51, each connector 51 has a first end and a second end, and each first end is composed of ten thousand The connection parts 411 of the connecting pieces 41 are respectively connected to the joints 52 , and each second end is respectively connected to the corresponding connection parts 242 of the left and right connecting rods 24 through a universal joint 52 .

The use mode, efficacy and characteristics of the elliptical exercise machine 1 are described below. During use, the user stands on the pedal 40 with both feet, and holds the handrail bar 25 with both hands. Linkage of bar 26 drives, and left and right two supporting bases 30 can keep relatively moving on an approximately elliptical track, and each pedal 40, connecting piece 41 and connecting piece 51 also move along the elliptical track with supporting base 30. At the same time, the distance between the support base 30 and the connecting portion 242 of the connecting rod 24 also changes periodically. From the side view, there is an angle α between the second half of the connecting rod 24 and the second half of the supporting rod 26, The included angle α varies between a predetermined maximum angle (as shown in FIG. 4 ) and a predetermined minimum angle (as shown in FIG. 7 ).

Since there is a fixed length between the first end and the second end of the connecting member 51 , a fixed distance must also be maintained between the connecting portion 411 of the connecting piece 41 and the connecting portion 242 of the connecting rod 24 . When the distance between the support base 30 and the connecting portion 242 of the connecting rod 24 is reduced, the connecting portion 242 of the connecting rod 24 approaches the supporting base 30. At this time, the connecting piece 51 is pushed by the connecting rod 24, so that the first end of the connecting piece 51 is pushed to connect. plate 41, thereby causing the pedal 40 to move laterally outward along the slide rail 31. Conversely, when the distance between the support base 30 and the connecting rod 24 increases, the connecting member 51 is pulled by the connecting rod 24 , so that the pedal 40 moves laterally inward along the slide rail 31 .

As can be seen from the above, when the support base 30 moves along the closed track, viewed from the side, the pedal 40 installed on the support base 30 moves along the track with the support base 30, and when viewed from the top down, the pedal 40 is also opposite to each other at the same time. The support base 30 moves left and right.

The complete motion cycle of the pedal 40 and the support base 30 will be described in detail below based on FIGS. Components such as the support base 30, the pedal 40, the connecting piece 41, the connecting piece 51 and the connecting rod 24. As shown in FIGS. 4 to 6 , when the support base 30 is located at a relatively high position (hereinafter referred to as the first position) in a closed trajectory, the pedal 40 is located at an inner position. When the support base 30 moves forward and downward along the track, the pedal 40 not only moves forward and downward synchronously, but also moves outward relative to the support base 30 at the same time. As shown in FIGS. 7 to 9 , when the support base 30 moves to a relatively lower position (hereinafter referred to as the second position), the pedal 40 moves outward to an outer position. When the support base 30 moves backward and upward along the track, the pedal 40 also moves inward relative to the support base 30 at the same time. When the support base 30 moves back to the aforementioned first position, the pedal 40 also returns to the aforementioned inner position.

If one side pedal 40 is observed from the rear, its trajectory moves from the inside position above to the outside position below, and then returns to the inside position above, forming a plane inclined relative to the ground or a curved surface close to the plane. The movement track of the pedal 40 also forms a symmetrical inclined plane or inclined curved surface. Thus, the two inclined planes or two inclined curved surfaces formed by the left and right side pedals 40 are in a relative relationship of being narrow at the top and wide at the bottom.

In this embodiment, the inner and outer positions of the pedal 40 correspond to the relatively higher and lower positions of the support base 30 respectively, but in other embodiments, the inner and outer positions of the pedal 40 are not necessarily at a relatively high point Or a relatively low point, which can be set at a predetermined position in the trajectory according to different design purposes and requirements, and the first position and the second position in the closed trajectory do not need to be symmetrical. For example, the second end of the connecting member 51 is set to be connected to an appropriate position, so that the inner position of the pedal 40 is located in the relative front of the closed track, and the outer position is located in the relative rear of the closed track, so that the aforementioned patent No. M262216 can also be achieved. Described in the case, the effect that the two side pedals 40 track distances are narrow in the front and wide in the rear. Similarly, if the second end of the connecting piece 51 is set at a proper position, the effects of widening at the front and narrowing at the rear, widening at the top and narrowing at the bottom can all be realized.

By using the elliptical exercise machine with the above structure, in addition to the movement of the legs in the front, rear, up and down directions, the user's legs also move in the left and right directions due to the displacement of the pedal 40 relative to the support base 30 during the exercise process, thus the legs can be trained. The side muscles and ankles can be used to increase the variability of movement and increase the amount of exercise.

Finally, it must be added that the elliptical exercise machine described above and shown in the accompanying drawings is only a preferred embodiment of the present invention, and does not therefore limit the possible implementation scope and patent scope of the present invention. For example, firstly, the second end of the connecting piece 51 can be connected to a connecting portion at an appropriate place of the frame body 10 except being connected to the connecting portion 242 of the connecting rod 24 or other parts of the guiding mechanism 20, and the frame body 10 can be used to The change of the distance between the connecting portion of the body 10 and the supporting base 30 makes the connecting piece 51 force the pedal 40 to move left and right relative to the supporting base 30 along the direction of the slide rail 31 . Second, there are many kinds of guiding mechanisms for guiding the pedals to move along the closed track in the elliptical exercise machine. The present invention can be applied to various elliptical exercise machines, and can also achieve the same effect. Third, the linkage mechanism can also be a screw device driven by a motor. This device is installed on the support base, the pedal is erected on the screw, and the motor is used to drive the screw to rotate in situ, so that the pedal can move left and right. At the same time, the motor is connected through a circuit. To the console, the cycle of the pedal moving left and right can be consistent with the cycle of the guide mechanism. The 4th, interlocking mechanism also can be the gear transmission device that is formed by gear and screw rod, screw rod is installed between support seat and pedal equally, gear is installed at connecting rod and support bar pivot joint in addition, and screw rod and The aforementioned gears are connected and driven by racks, gears or chains, and the gears are driven to rotate by the variation of the included angle α between the connecting rod and the support rod, and then the screw rod is driven to rotate, so that the pedal can move left and right.

To sum up, the elliptical exercise machine of the present invention provides another exercise mode, which increases the movement in the left and right directions during the leg exercise process, which not only increases the variability of exercise, but also increases the amount of leg exercise. - An innovative design with industrial value.
