Problems solved by technology

Therefore, in order to improve the aforesaid deficiency, some operators increase the diameter length of the crank 13, enlarge the circular locus at the front end of the pedal shaft 14, and enlarge the elliptical locus in the middle of the pedal shaft 14 correspondingly. Such a design method, It will inevitably increase the size of the elliptical machine (drive system), and in the case of an elliptical trajectory that is scaled up in equal proportions, the movement still does not conform to ergonomics (to put it simply, the ideal trajectory should not only have a wider banner, but also a flatter overall ratio)
[0005] 2. Since the pedals 15 are fixed on the top surfaces of the pedal shafts 14 in a fixed manner, the positioning angle with the pedal shafts 14 cannot be changed. Therefore, when the pedal shafts 14 move along an elliptical trajectory , will produce different inclination angles due to the change of the angle, so that the pedals 15 are inclined with the inclination of the pedal shafts 14, so, in the process of exercise, the pedals 15 cannot provide the user with a full range of motion. A stable supporting effect of the foot causes part of the movement stroke, especially when the pedal shafts 14 advance to the upper and lower poles, the heel will be lifted and the situation in the air will be raised. In this case, the user can easily In the process of exercising, the hamstring tendons may be pulled, making the feet prone to fatigue and unable to carry out long-term exercise
[0006] 3. And because the motion stroke of the aforementioned elliptical exercise machine 1 is often fixed and cannot be changed, for users with different exercise demands, or users with different statures, the swing stroke may be too large or the swing stroke may be too large. If the size is too small, the user's feet will be stretched too much or the amount of exercise will be insufficient, causing the user to succumb to the aforementioned swing stroke, and there may be doubts about sports injuries due to poor posture

Embodiment Construction

[0023] refer to figure 2 , image 3 , The preferred embodiment of the elliptical exercise machine of the present invention includes a body 2 , two sliding devices 3 , two pedal devices 4 , two extension devices 5 and two linkage devices 6 .

[0024] The body 2 has a base 21 , an instrument panel frame 22 , a rail seat 23 and two rotating parts 24 . The base 21 has a front end 211 and a rear end 212 opposite to each other. The instrument panel frame 22 stands on the front end 211 of the base 21 . The rail seat 23 is formed on the rear end portion 212 of the base 21 . In this embodiment, the rotating parts 24 are respectively a disk, which are coaxially pivoted at the position of the base 21 adjacent to the front end 211, and arranged on the left and right sides. The rotating parts 24 are It can rotate around a center line I. It is worth mentioning that the first preferred embodiment is a front-drive elliptical machine, mainly a drive system (including drive shaft, driven f...

Abstract

The invention discloses an ellipse sport device, comprises a main body, two slide device, two footplate devices, and two extension devices. Wherein, said main body has two rotary elements rotating around one axis; each of said slid devices has a slide rod axially connected to the rotary element and sliding front-back along it; each of said footplate devices comprises a footplate movably mounted on said slide rod; each of extension devices has a rotary arm axially connected with said slide rod, a interlocking arm axially connecting said footplate and said rotary arm, and a interlocking unit for driving reverse rotation of said rotary arm. Therefore, the footplate can make a prolate ellipsoid motion track.

Description

technical field [0001] The invention relates to an elliptical exercise machine, in particular to an elliptical exercise machine capable of enlarging the lateral range of a motion track to conform to ergonomics. Background technique [0002] Referring to Figure 1, taking a general elliptical exercise machine 1 as an example, it mainly includes: a base 11, an instrument panel frame 12 standing on a front end 111 of the base 11, a rotatable mounting on the base 11 and two cranks 13 adjacent to the front end 111, two pedal shafts 14 that are pivotally connected to the cranks 13 and slide on a rear end 112 of the base 11, respectively fixed on the pedal shafts 14 Two pedals 15 , two swing arms 16 pivotally connected to the instrument panel frame 12 respectively, and two connecting rods 17 pivotally connected to the swing arms 16 and connected to the pedals 15 respectively. [0003] In this way, the user only needs to stand on the pedals 15, respectively apply a forward and backw...
