技术领域 technical field

本发明涉及运动器材，特别是指一种椭圆运动机。The invention relates to sports equipment, in particular to an elliptical exercise machine.

背景技术 Background technique

椭圆运动机是近年新兴的一种运动健身器材，一般泛指各种能导引左、右二踏板沿着近似椭圆形的轨迹运动，以供使用者进行模拟走路、跑步、登阶等腿部运动的装置。The elliptical exercise machine is a new kind of sports and fitness equipment in recent years. It generally refers to all kinds of legs that can guide the left and right pedals to move along an approximately elliptical trajectory for users to simulate walking, running, and climbing steps. Movement device.

一般椭圆运动机的左、右二侧踏板，各沿一封闭轨迹移动，这些封闭轨迹多半固定不变，因此使用者的腿部运动型态也是一成不变，使得运动过程缺乏变化而单调无趣。习知技艺中也具有若干可调整踏板轨迹的椭圆运动机结构，可调整椭圆形轨迹的长轴倾角，如图1及图2所示的一种具调整倾角功能的椭圆机1，椭圆机1包括有一供稳定放置在地面上的第一基架11及一供安装椭圆机构的第二基架12，第二基架12与第一基架11以一枢转装置相互枢接，使第二基架12可相对第一基架11旋转，其中，椭圆机构的基本构造包括有一飞轮、二个曲柄、二个踏板臂，每一曲柄的第一端与飞轮同轴连接固定，每一曲柄的第二端分别枢接在相对的每一踏板臂的第一端，且每一踏板臂上设有踏板，当使用者脚踩在踏板上，其踏板臂第一端随着曲柄转动时，该踏板可做椭圆轨迹运动。通过采用上述整体结构，使得此椭圆机构具有调整倾角的功能，让使用者能依需要调整运动难易度。Generally, the left and right side pedals of an elliptical exercise machine move along a closed track, and these closed tracks are mostly fixed, so the user's leg movement pattern is also invariable, making the exercise process lack of change and monotonous. There are also some elliptical motion machine structures with adjustable pedal tracks in the prior art, which can adjust the inclination angle of the major axis of the elliptical track, as shown in Figure 1 and Figure 2, a kind of elliptical machine 1 with the function of adjusting the inclination angle, elliptical machine 1 It includes a first base frame 11 for stable placement on the ground and a second base frame 12 for installing an elliptical mechanism, the second base frame 12 and the first base frame 11 are pivotally connected to each other by a pivoting device, so that the second The base frame 12 is rotatable relative to the first base frame 11, wherein the basic structure of the elliptical mechanism includes a flywheel, two cranks, and two pedal arms, the first end of each crank is coaxially connected and fixed with the flywheel, and each crank The second end is respectively pivotally connected to the first end of each opposite pedal arm, and each pedal arm is provided with a pedal. When the user steps on the pedal, the first end of the pedal arm rotates with the crank. The pedals can do elliptical trajectory movement. By adopting the above overall structure, the elliptical mechanism has the function of adjusting the inclination angle, so that the user can adjust the difficulty of exercise according to needs.

虽然椭圆机1的踏板运动轨迹可供使用者调整，但由于控制台(图中未示)及握把14装设于第一基架11侧边的支柱13上，当踏板轨迹变化时，控制台及握把14仍留在原地，造成控制台、握把14与使用者之间的距离及角度产生变化，使得控制台、握把14过于接近或远离使用者，如此不但造成使用不便，当角度变化太大时，更可能造成看不清楚控制台屏幕讯息的困扰。Although the pedal trajectory of the elliptical machine 1 can be adjusted by the user, since the console (not shown) and the handle 14 are installed on the pillar 13 on the side of the first base frame 11, when the pedal trajectory changes, the control Platform and handle 14 remain in place, causing the distance and angle between the console, handle 14 and the user to change, making the console, handle 14 too close to or far away from the user, which not only causes inconvenience in use, but also When the angle changes too much, it is more likely to cause troubles that the console screen information cannot be read clearly.

接着说明上述椭圆运动机2的使用方式及其功效。如图6、图7所示，为了让视图清楚呈现，在此将架体20的弧形支架23移除。图6所示的第一活动杆42处于一相对低点的第一位置，此时第一活动杆42与底座21之间的夹角α具有一最小角度，此时，可调机构40整体外观约略呈现一平行四边形的形状。如图6所示，枢接于第一活动杆42的第一导引机构50，以及连接于第二活动杆43的立杆45、控制台81、及第三导引机构90等也处于一相对低点。Next, the usage and efficacy of the above-mentioned elliptical exercise machine 2 will be described. As shown in FIG. 6 and FIG. 7 , in order to make the view clear, the arc-shaped bracket 23 of the frame body 20 is removed here. The first movable rod 42 shown in FIG. 6 is in a relatively low first position. At this time, the angle α between the first movable rod 42 and the base 21 has a minimum angle. At this time, the overall appearance of the adjustable mechanism 40 Approximately presents the shape of a parallelogram. As shown in Figure 6, the first guide mechanism 50 pivotally connected to the first movable rod 42, and the vertical rod 45 connected to the second movable rod 43, the console 81, and the third guide mechanism 90 etc. are also in one position. Relatively low.

当使用者在此状态使用椭圆运动机2时，由于第一导引机构50处于相对低点，因此第一封闭轨迹T1也位于相对低点。受曲柄53与支撑杆31的导引，悬臂61摆荡端63移动的弧形轨迹也位于相对低点。因此，当支撑杆31第一端311、第二端312分别沿第一封闭轨迹T1及圆弧轨迹T3运动，由于第一导引机构50处于相对低点，则踏板33所运动的第二封闭轨迹T2也处于相对低点位置。When the user uses the elliptical exercise machine 2 in this state, since the first guiding mechanism 50 is at a relatively low point, the first closed trajectory T1 is also at a relatively low point. Guided by the crank 53 and the support rod 31, the arc track of the swing end 63 of the cantilever 61 is also located at a relatively low point. Therefore, when the first end 311 and the second end 312 of the support rod 31 move along the first closed track T1 and the arc track T3 respectively, since the first guide mechanism 50 is at a relatively low point, the second closed track moved by the pedal 33 Track T2 is also at a relatively low point.

若使用者想要调整踏板33运动的轨迹(即第二封闭轨迹)，则可通过操作控制台81，使马达71带动螺杆72旋转，即可驱动第一活动杆42相对枢轴47转动，使第一活动杆42与底座21之间的夹角α增大，并带动第一导引机构50朝架体20第一端上方提升，使得第一导引机构50与悬臂61圆心端62之间的距离增加。如图7所示，当第一活动杆42借由马达71与螺杆72的推动而相对于架体20产生偏转时，当第一活动杆42的第二端处于一相对高点的第二位置时，则第一活动杆42与底座21之间的夹角α具有一最大角度。第二活动杆43受到第一活动杆42的推动，朝架体20第一端上方移动，由于第三活动杆44的第二端枢接在固定杆41上，第一端枢接在第二活动杆43第二端，因此，当第一活动杆41受到螺杆72推动而往架体20第一端上方移动时，则第三活动杆会一并受到第一活动杆41的压迫而朝架体20第一端上方移动，使可调装置40的外观从原本的平行四边形转变为类似菱形的外观。If the user wants to adjust the track of pedal 33 motion (i.e. the second closed track), then the motor 71 can drive the screw rod 72 to rotate by operating the console 81, so that the first movable rod 42 can be driven to rotate relative to the pivot 47, so that The angle α between the first movable rod 42 and the base 21 increases, and drives the first guide mechanism 50 to lift upward toward the first end of the frame body 20, so that the gap between the first guide mechanism 50 and the center end 62 of the cantilever 61 distance increases. As shown in FIG. 7 , when the first movable rod 42 is deflected relative to the frame body 20 by the promotion of the motor 71 and the screw rod 72 , when the second end of the first movable rod 42 is at a relatively high second position , the angle α between the first movable rod 42 and the base 21 has a maximum angle. The second movable rod 43 is pushed by the first movable rod 42 and moves above the first end of the frame body 20. Since the second end of the third movable rod 44 is pivotally connected to the fixed rod 41, the first end is pivotally connected to the second The second end of the movable rod 43, therefore, when the first movable rod 41 is pushed by the screw rod 72 and moves above the first end of the frame body 20, the third movable rod will be pressed by the first movable rod 41 and move toward the frame. Moving above the first end of the body 20 changes the appearance of the adjustable device 40 from the original parallelogram to a rhombus-like appearance.

由于第一导引机构50朝架体20第一端上方提升，故第一封闭轨迹T1也随之提升，同时使枢接于曲柄53的支撑杆31第一端311朝架体20第一端上方移动。如此一来，支撑杆31第二端312也会被带动而朝架体20第一端上方移动，但由于支撑杆31第二端312枢接于悬臂61，因此悬臂61摆荡端63受支撑杆31第二端312拉动而朝架体20第一端上方移动，使圆弧轨迹T3以悬臂61圆心端62为圆心，圆心端62与摆荡端63之间的距离为半径，沿着原本的圆弧轨迹T3延伸，朝架体20第一端上方移动并改变倾斜程度，形成位于相对高点的圆弧轨迹T3。由于支撑杆31第一端及第二端都朝架体20第一端上方移动，因此装设在支撑杆31上的踏板33，其第二封闭轨迹T2也朝架体20第一端上方移动，如图6所示，调整前的第二封闭轨迹T2长轴较为接近水平，请一并参照图7，调整后的第二封闭轨迹T2长轴较为倾斜。由此，即可达成调整踏板33运动轨迹的目的。Since the first guide mechanism 50 is lifted toward the top of the first end of the frame body 20, the first closed track T1 is also lifted accordingly, and at the same time, the first end 311 of the support rod 31 pivotally connected to the crank 53 is moved toward the first end of the frame body 20. Move up. In this way, the second end 312 of the support rod 31 will also be driven to move above the first end of the frame body 20, but since the second end 312 of the support rod 31 is pivotally connected to the cantilever 61, the swing end 63 of the cantilever 61 is supported by the support rod. 31 The second end 312 pulls and moves toward the top of the first end of the frame body 20, so that the arc track T3 takes the center end 62 of the cantilever 61 as the center of the circle, and the distance between the center end 62 and the swing end 63 is the radius, along the original circle The arc track T3 extends, moves toward the top of the first end of the frame body 20 and changes the degree of inclination, forming an arc track T3 at a relatively high point. Since the first end and the second end of the support rod 31 both move above the first end of the frame body 20, the second closed track T2 of the pedal 33 installed on the support rod 31 also moves above the first end of the frame body 20. , as shown in FIG. 6 , the long axis of the second closed trajectory T2 before adjustment is relatively close to the horizontal. Please also refer to FIG. 7 , the long axis of the adjusted second closed trajectory T2 is relatively inclined. Thus, the purpose of adjusting the movement track of the pedal 33 can be achieved.

再如图7所示，在活动组件及固定杆41所构成的平行四边形中，当调整装置70调整第一活动杆42，使其相对枢轴47旋转时，第二活动杆43相对于固定杆41，及第一活动杆42相对于第三活动杆44均保持大致平行的状态。又因固定杆41固定于底座21上，故第二活动杆43在调整过程中，第二活动杆43会以约略平行于固定杆41的移动方向，朝架体20第一端上方移动。由于立杆45固设于第二活动杆43上，因此立杆45会随第二活动杆43朝架体20第一端上方提升。As shown in Figure 7 again, in the parallelogram formed by the movable assembly and the fixed rod 41, when the adjustment device 70 adjusts the first movable rod 42 to make it rotate relative to the pivot 47, the second movable rod 43 is relatively opposite to the fixed rod. 41 , and the first movable rod 42 are maintained substantially parallel to the third movable rod 44 . And because the fixed rod 41 is fixed on the base 21, so the second movable rod 43 is in the adjustment process, the second movable rod 43 will move toward the top of the first end of the frame body 20 in a direction roughly parallel to the moving direction of the fixed rod 41. Since the upright rod 45 is fixed on the second movable rod 43 , the upright rod 45 will be lifted upwards toward the first end of the frame body 20 along with the second movable rod 43 .

设于立杆45第一端的控制台81，在可调机构40由相对低点的第一位置调整至相对高点的第二位置时，随立杆45朝架体20第一端上方大致呈平行移动，且在调整前后，控制台81上表面大致平行，也即调整前后控制台81上表面保持大致相同的倾斜角度。如此一来，当使用者操作控制台81以调整踏板33运动轨迹时，控制台81可随踏板33运动轨迹变化而产生相对应的移动，使控制台81相对使用者的距离及视角维持大致相同，不但方便使用者操控，也不至于因视角变化而使得使用者看不清楚控制台81所示的讯息。The console 81 located at the first end of the vertical pole 45, when the adjustable mechanism 40 is adjusted from the first position of the relatively low point to the second position of the relatively high point, moves toward the top of the first end of the frame body 20 with the vertical pole 45 approximately It moves in parallel, and before and after the adjustment, the upper surface of the console 81 is approximately parallel, that is, the upper surface of the console 81 maintains approximately the same inclination angle before and after adjustment. In this way, when the user operates the console 81 to adjust the movement trajectory of the pedal 33, the console 81 can move correspondingly with the change of the movement trajectory of the pedal 33, so that the distance and viewing angle of the console 81 relative to the user remain approximately the same , which is not only convenient for the user to operate, but also prevents the user from being able to clearly see the information displayed on the console 81 due to changes in the viewing angle.

同理，枢设于立杆45二侧的第三导引机构90，在可调机构40由相对低点的第一位置调整至相对高点的第二位置时，随立杆45朝架体20第一端上方提升，其二摆臂91顶端的握把92也同步提升。如此，当使用者操作控制台81以调整踏板33运动轨迹时，握把92相对使用者的距离维持大致相同，方便使用者抓握。In the same way, the third guide mechanism 90, which is pivotally arranged on both sides of the vertical rod 45, when the adjustable mechanism 40 is adjusted from the first position of the relatively low point to the second position of the relatively high point, moves toward the frame body with the vertical rod 45. 20 first end tops promote, and the grip 92 of its two swing arms 91 tops also promotes synchronously. In this way, when the user operates the console 81 to adjust the movement trajectory of the pedal 33 , the distance between the handle 92 and the user remains approximately the same, which is convenient for the user to grasp.

最后必须补充说明的是，以上所述及图中所示的椭圆运动机，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。举例而言，可调机构也可以是一伸缩杆结构，具有一固定件及一活动组件，固定件固设于架体，活动组件与固定件相互套设并可相对固定件滑移，以改变可调机构相对于架体的位置。Finally, it must be added that the elliptical exercise machine described above and shown in the figure 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. For example, the adjustable mechanism can also be a telescopic rod structure with a fixed part and a movable component, the fixed part is fixed on the frame body, the movable component and the fixed part are nested with each other and can slide relative to the fixed part to change The position of the adjustable mechanism relative to the frame body.

综上所述，本发明的椭圆运动机，除可供使用者依据个人需求设定不同的踏板轨迹，也可保持控制台与使用者之间的适当距离及角度，方便使用者操作及观看，更可达到握把与使用者之间保持适当距离，方便使用者抓握的目的，实为一创新设计并具有产业价值。To sum up, the elliptical exercise machine of the present invention can not only allow the user to set different pedal tracks according to individual needs, but also maintain an appropriate distance and angle between the console and the user, which is convenient for the user to operate and watch. It can also achieve the purpose of maintaining an appropriate distance between the grip and the user and making it convenient for the user to grasp. This is an innovative design and has industrial value.
