技术领域technical field

It generally refers to all kinds of equipment that can guide the left and right pedals to move along an approximately elliptical trajectory for users to simulate walking, running, climbing steps and other leg movements. device.

美国第6,390,954号专利便揭示了一种椭圆机结构，简要来说，它是在一架体前端设一曲柄机构，并在架体后端设置贴近地面的左、右二导轨；左、右二侧各有一支撑杆，各支撑杆将其前端枢接在曲柄机构的其中一曲柄臂，使得可沿一圆形轨迹绕转，并在后端枢设一滚轮，可在对应的导轨上前后滑移，同时，支撑杆的中段顶面设有一可供踩踏的踏板；此外，架体前端还设有左、右二摆臂，各摆臂顶端形成一活动握把，底端与对应的支撑杆之间连接一连杆，使二者可相互带动。由此，左、右二踏板可在一近似椭圆形的封闭轨迹上循环运动，而左、右二握把也可与踏板协调地进行偏摆运动。The U.S. No. 6,390,954 patent discloses a structure of an elliptical machine. Briefly, it is to set a crank mechanism at the front end of a frame body, and set two left and right guide rails close to the ground at the rear end of the frame body; There is a support rod on each side, and each support rod pivotally connects its front end to one of the crank arms of the crank mechanism, so that it can revolve along a circular track, and a roller is pivoted at the rear end, which can slide forward and backward on the corresponding guide rail. At the same time, there is a pedal on the top surface of the middle section of the support rod; in addition, the front end of the frame body is also provided with two left and right swing arms, and the top of each swing arm forms a movable handle, and the bottom end is connected with the corresponding support rod.

下面接着说明椭圆机1的使用方式及其功效。如图2、图3所示，为便于清晰表现结构，在图3以后的附图中去除二摆臂71，以及其中一组第一连杆40、第二连杆50、第三连杆60及对应的支撑杆80、悬臂31、踏板81。在本实施例中，第一组定位孔34、第二组定位孔35及第三组定位孔42各具有三个定位孔，且第一定位栓41、第二定位栓52及第三定位栓61分别枢接于第一组定位孔34、第二组定位孔35及第三组定位孔42的中间定位孔。当使用者使用椭圆机1时，第一连杆40第一端、第二端分别沿第一封闭轨迹T1及第一圆弧轨迹T3运动，使悬臂31摆动并带动第二连杆50运动，接着再通过枢接部51的连动，导引踏板81沿一第二封闭轨迹T20运动，其中，第一封闭轨迹T1具有一第一水平长度D1，第二封闭轨迹T20具有一长轴，长轴具有一第二水平长度D2。在本实施例中，水平长度为各轨迹中，前后折返点之间的直线连接距离。Next, the usage and efficacy of theelliptical machine 1 will be described. As shown in Fig. 2 and Fig. 3, for the convenience of clearly showing the structure, the twoswing arms 71 and one group of the first connectingrod 40, the second connectingrod 50 and the third connectingrod 60 are removed in the drawings after Fig. 3 Andcorresponding support bar 80,cantilever 31,pedal 81. In this embodiment, the first set ofpositioning holes 34, the second set ofpositioning holes 35 and the third set ofpositioning holes 42 each have three positioning holes, and thefirst positioning pin 41, thesecond positioning pin 52 and thethird positioning pin 61 are respectively pivotally connected to the middle positioning holes of the first group ofpositioning holes 34 , the second group ofpositioning holes 35 and the third group ofpositioning holes 42 . When the user uses theelliptical machine 1, the first end and the second end of the first connectingrod 40 move along the first closed track T1 and the first arc track T3 respectively, so that thecantilever 31 swings and drives the second connectingrod 50 to move, Then, through the linkage of thepivot joint 51, theguide pedal 81 moves along a second closed track T20, wherein the first closed track T1 has a first horizontal length D1, and the second closed track T20 has a major axis, the length of which is The shaft has a second horizontal length D2. In this embodiment, the horizontal length is the straight-line connection distance between the front and back turning points in each trajectory.

如图4所示，为椭圆机1在此状态下悬臂31可摆荡的最大幅度，其间具有一夹角α。第一定位栓41、第二定位栓52分别沿第一圆弧轨迹T3、第二圆弧轨迹T4往复运动，第一圆弧轨迹T3较小，而第二圆弧轨迹T4较大，二者的比例为第一定位栓41至圆心部32的距离相比于第二定位栓52至圆心部32的距离。由于第一圆弧轨迹T3、第二圆弧轨迹T4的放大效果，使第二水平长度D2大于第一水平长度D1，因此椭圆机1可以利用较小的整体结构，提供足够长度的脚部运动行程。As shown in FIG. 4 , it is the maximum amplitude that thecantilever 31 of theelliptical machine 1 can swing in this state, and there is an included angle α therebetween. Thefirst positioning pin 41 and thesecond positioning pin 52 reciprocate respectively along the first circular arc track T3 and the second circular arc track T4, the first circular arc track T3 is relatively small, and the second circular arc track T4 is relatively large. The ratio of is the distance from thefirst positioning pin 41 to thecenter portion 32 compared to the distance from thesecond positioning pin 52 to thecenter portion 32 . Due to the magnification effect of the first arc track T3 and the second arc track T4, the second horizontal length D2 is greater than the first horizontal length D1, so theelliptical machine 1 can use a smaller overall structure to provide sufficient length of foot movement journey.

再如图5所示，第一定位栓41由中间定位孔向上调整，使第一连杆40第二端朝向悬臂31圆心部32移动及定位，此时第一定位栓41至悬臂31圆心部32的距离减小，使得夹角α的角度增加，悬臂31的摆荡幅度加大，间接使第二圆弧轨迹T4的行程加大，导致第二封闭轨迹T20的长轴加长，也就是移动后的第二封闭轨迹T21的水平长度比移动前的第二封闭轨迹T20的水平长度大。相反地，若将第一定位栓41由中间定位孔反向调整，则使得夹角α的角度减小，进而导致第二封闭轨迹T20的水平长度减小。As shown in Figure 5 again, thefirst positioning pin 41 is adjusted upwards by the middle positioning hole, so that the second end of the first connectingrod 40 moves and locates toward thecenter portion 32 of thecantilever 31. At this time, thefirst positioning pin 41 reaches the center portion of thecantilever 31 The distance of 32 decreases, so that the angle of included angle α increases, and the swing amplitude of thecantilever 31 increases, which indirectly increases the stroke of the second arc track T4, resulting in the lengthening of the long axis of the second closed track T20, that is, after the movement The horizontal length of the second closed trajectory T21 is greater than the horizontal length of the second closed trajectory T20 before the movement. On the contrary, if thefirst positioning pin 41 is reversely adjusted from the middle positioning hole, the included angle α decreases, which in turn reduces the horizontal length of the second closed track T20 .

如图6所示，为第一定位栓41枢接于第一组定位孔34的中间定位孔，将第二定位栓52由第二组定位孔35的中间定位孔向上调整，使第二连杆50第二端朝向悬臂31圆心部32移动及定位，此时第二定位栓52至圆心部32的距离减小，也就是夹角α的角度不变，但摆荡半径缩小，间接使第二圆弧轨迹T4的行程缩小，导致第二封闭轨迹T20的长轴缩短，也就是移动后的第二封闭轨迹T22的水平长度比移动前的第二封闭轨迹T20的水平长度小。相反地，若将第二定位栓52由中间定位孔反向调整，则摆荡半径增大，第二封闭轨迹T20的水平长度也随之增大。As shown in Figure 6, thefirst positioning bolt 41 is pivotally connected to the middle positioning hole of the first group of positioning holes 34, and thesecond positioning bolt 52 is adjusted upwards from the middle positioning hole of the second group of positioning holes 35, so that the second connecting The second end of therod 50 moves and locates toward thecenter portion 32 of thecantilever 31. At this time, the distance from thesecond positioning pin 52 to thecenter portion 32 decreases, that is, the angle of the included angle α remains unchanged, but the swing radius decreases, which indirectly makes the second The shortening of the stroke of the arc track T4 results in the shortening of the long axis of the second closed track T20, that is, the horizontal length of the second closed track T22 after the movement is smaller than that of the second closed track T20 before the movement. Conversely, if thesecond positioning pin 52 is reversely adjusted from the middle positioning hole, the swing radius increases, and the horizontal length of the second closed track T20 also increases accordingly.

接着如图7所示，图中第一定位栓41、第二定位栓52分别枢接于第一组定位孔34及第二组定位孔35的中间定位孔，并将第三定位栓61由第三组定位孔42的中间定位孔，向第一连杆40第二端移动及定位，此时第一定位栓41、第二定位栓52至悬臂31圆心部32之间的距离没有改变，而第二连杆50相对于底座11的倾斜程度被调整，进而改变踏板运行的第二封闭轨迹T20。在本实施例中，第三定位组件93在移动及定位之后，使第二封闭轨迹T20的长轴由二端大致呈水平的一平缓状态，改变为一端较高的倾斜状态，也就是移动后的第二封闭轨迹T23比移动前的第二封闭轨迹T20倾斜，达到调整脚部运动行程的目的，进而改变使用者的运动强度。Then as shown in Figure 7, thefirst positioning pin 41 and thesecond positioning pin 52 are respectively pivotally connected to the middle positioning holes of the first set of positioning holes 34 and the second set of positioning holes 35, and thethird positioning pin 61 is moved by The middle positioning hole of the third group of positioning holes 42 moves and locates toward the second end of the first connectingrod 40. At this time, the distance between thefirst positioning pin 41, thesecond positioning pin 52 and thecenter portion 32 of thecantilever 31 does not change. The degree of inclination of the second connectingrod 50 relative to thebase 11 is adjusted, thereby changing the second closed track T20 of pedal operation. In this embodiment, after thethird positioning assembly 93 moves and positions, the long axis of the second closed track T20 is changed from a gentle state in which two ends are roughly horizontal to a higher inclined state at one end, that is, after the movement The second closed track T23 is inclined compared with the second closed track T20 before the movement, so as to achieve the purpose of adjusting the movement stroke of the feet, thereby changing the exercise intensity of the user.

综上所述，本发明的椭圆机，除可以较小的结构，提供足够长度的脚步运动行程外，其脚部运动行程还可供使用者调整，实为一创新设计并具有产业价值。To sum up, the elliptical machine of the present invention, in addition to providing a sufficient length of foot movement stroke with a relatively small structure, its foot movement stroke can also be adjusted by the user, which is an innovative design and has industrial value.

最后必须补充说明的是，以上所述及附图中所示的椭圆机，仅是本发明的较佳实施型态，并不因此限定本发明的可能实施范围及专利保护范围。Finally, it must be added that the elliptical machine described above and shown in the accompanying drawings is only a preferred implementation form of the present invention, and does not therefore limit the possible implementation scope and patent protection scope of the present invention.
