Description
本發明與運動器材有關，進一步而言，是關於橢圓運動機(elliptical)。 The present invention relates to sports equipment, and further relates to an elliptical.
圖15顯示一種習知的橢圓運動機(9)(註：例如美國第7946962號專利案中所揭露的較佳實施例，但此處無意討論其獲准專利的技術特徵)，簡要來說，此種型式的橢圓運動機是利用左、右二導引臂(91)分別支撐供使用者踩踏的左、右二踏板(92)，各導引臂(91)的前端樞接在一曲柄臂(93)的外端，導引其沿一圓形軌跡作繞圓運動，各導引臂(91)的後端樞設一滾輪(94)並且搭配在一導軌(95)上，導引其沿一直線軌跡作往復運動，對應於此，樞設在導引臂(91)前、後二端之間的前述踏板(92)會沿著一類似橢圓形的封閉軌跡循環運動，模擬跑步時的腳部軌跡；此外，各導引臂(91)的外側具有一連動臂(96)，各連動臂(96)的前端樞接在一擺臂(97)的底端，導引其沿一圓弧軌跡前後擺盪，各連動臂(96)的後端與樞設在導引臂(91)上的前述踏板(92)固接，使得踏板(92)相對於導引臂(91)的角度能夠隨著前述循環運動而周期性變化，模擬跑步時的腳底角度變化。 Figure 15 shows a conventional elliptical exercise machine (9) (Note: for example, the preferred embodiment disclosed in U.S. Patent No. 7,946,962, but here is not intended to discuss the technical features of the patent application), in brief, this The elliptical exercise machine uses the left and right guide arms (91) to respectively support the left and right pedals (92) for the user to step on, and the front ends of the guide arms (91) are pivotally connected to a crank arm ( The outer end of 93) is guided to move around a circular path, and a rear end of each guiding arm (91) is pivoted with a roller (94) and is matched with a guide rail (95) to guide the edge thereof. A linear trajectory reciprocates, correspondingly, the pedal (92) pivoted between the front and rear ends of the guiding arm (91) will circulate along a closed elliptical trajectory to simulate the foot during running. In addition, the outer side of each guiding arm (91) has a linking arm (96), and the front end of each linking arm (96) is pivotally connected to the bottom end of a swing arm (97) to guide it along an arc The trajectory oscillates back and forth, and the rear end of each linkage arm (96) is fixed to the aforementioned pedal (92) pivoted on the guiding arm (91), so that the angle of the pedal (92) relative to the guiding arm (91) With the circular motion changes periodically, when the simulated running foot angle changes.
橢圓運動機(9)如上運作時，相互樞接的任意二構件會分別依一對應於左右方向的樞接軸線相對偏轉，例如，導引臂(91)與曲柄臂(93)會依彼此之間的樞接軸線(X1)相對偏轉，導引臂(91)與踏板(92)/連動臂(96)會依彼此之間的樞接軸線(X2)相對偏轉，連動臂(96)與擺臂(97)會依彼此之間的樞接軸線(未標號)相對偏轉，諸如此類。然而，如圖16及圖17所示，在上揭橢圓運動機(9)中，導引臂(91)的前端與曲柄臂(93)的外端之間並非單純地透過一軸向對應於左右方向的樞軸直接樞接，而是採用類似萬向接頭(universal joint)的結構，亦即透過相互垂直的二樞軸形成可三維活動的連接關係，詳而言之，各曲柄臂(93)的外端固接一沿左右方向往外凸伸的軸銷 (931)，另有一軸筒(991)利用兩個銅套軸承(992)同軸樞套在軸銷(931)上，前述軸筒(991)的外部頂側直交地固接一圓柱形承座(993)，由承座(993)的頂面中央再往上凸伸一軸向垂直於軸筒(991)軸向的螺柱(994)；另一方面，各導引臂(91)的前端固接一板面垂直於導引臂(91)橫斷面的套接板(911)，前述套接板(911)上具有一穿孔(912)，並以穿孔(912)套設前述螺柱(994)，再於穿出套接板(911)頂側的螺柱(994)上適當螺合一螺栓(995)，使套接板(911)的底面貼抵前述承座(993)的頂面；藉此，導引臂(91)相對於曲柄臂(93)不僅能夠依據軸銷(931)/軸筒(991)的軸線上下偏轉，還能依據螺柱(994)的軸線左右偏轉(通常僅微幅偏轉)。 When the elliptical exerciser (9) operates as above, any two members that are pivotally connected to each other are respectively deflected according to a pivot axis corresponding to the left and right directions. For example, the guide arm (91) and the crank arm (93) are in accordance with each other. The pivot axis (X1) is relatively deflected, and the guiding arm (91) and the pedal (92)/linking arm (96) are deflected relative to each other according to the pivot axis (X2), and the arm (96) and the pendulum are connected. The arms (97) are deflected relative to each other by a pivot axis (not numbered), and the like. However, as shown in FIGS. 16 and 17, in the above-described elliptical exercise machine (9), the front end of the guide arm (91) and the outer end of the crank arm (93) are not simply transmitted through an axial direction corresponding to The pivots in the left-right direction are directly pivoted, but a structure similar to a universal joint is used, that is, a three-dimensionally movable connection relationship is formed through two mutually perpendicular pivots, in detail, each crank arm (93) The outer end of the ) is fixed to a shaft pin that protrudes outward in the left and right direction (931), another shaft cylinder (991) is coaxially pivoted on the shaft pin (931) by two copper sleeve bearings (992), and the outer top side of the shaft barrel (991) is fixedly fixed to a cylindrical socket. (993), a stud (994) axially perpendicular to the axial direction of the barrel (991) is projected upward from the center of the top surface of the socket (993); on the other hand, the front end of each guiding arm (91) A socket plate (911) perpendicular to a cross section of the guiding arm (91) is fixed, the socket plate (911) has a through hole (912), and the stud is sleeved by a hole (912) (994), and then a bolt (995) is appropriately screwed on the stud (994) on the top side of the sleeve plate (911), so that the bottom surface of the socket plate (911) is attached to the socket (993). The top surface; thereby, the guiding arm (91) can be deflected up and down not only according to the axis of the shaft pin (931) / the barrel (991), but also can be deflected left and right according to the axis of the stud (994) with respect to the crank arm (93). (usually only slightly deflected).
習知橢圓運動機(9)採用上揭連接結構的用意如下：因為前述導引臂(91)的中間部位與(固接在連動臂(96)後端的)踏板(92)之間是透過一軸向對應於左右方向的樞軸樞接，所以，假設導引臂(91)的前端與曲柄臂(93)之間也打算直接透過一軸向對應於左右方向的樞軸樞接，那麼，導引臂(91)、踏板(92)、曲柄臂(93)上的每個用以裝配或構成前述樞軸的樞接部位(例如軸銷、軸筒、軸孔等)，軸線角度都必須具有良好的精度，才能兩兩同軸妥適樞接，反過來說，如果某個構件上的某個樞接部位的軸線角度偏斜過大，則在進行組裝時，可能發生其中一對樞接部位完成樞接之後，另一對樞接部位卻無法或難以同軸對合的窘境，或者，雖然可以勉強接合，但因樞軸受力偏斜而影響運作順暢及構件壽命；習知橢圓運動機(9)在其導引臂(91)前端與曲柄臂(93)外端之間透過相互垂直的二樞軸進行連接，可以靈活吸收樞接部位的角度偏斜，使組裝容易、運作順暢。不過，上揭連接結構顯然過於複雜、成本較高。 The conventional elliptical exercise machine (9) adopts the upper uncovering connection structure as follows: since the middle portion of the guiding arm (91) and the pedal (92) fixed to the rear end of the linking arm (96) are transmitted through a The axial direction is pivotally connected to the pivot in the left-right direction. Therefore, if the front end of the guiding arm (91) and the crank arm (93) are also intended to be directly pivotally connected through a pivot corresponding to the left-right direction, then Each of the guiding arm (91), the pedal (92), and the crank arm (93) is used to assemble or constitute a pivotal portion of the pivot (such as a shaft pin, a shaft barrel, a shaft hole, etc.), and the axis angle must be With good precision, the two coaxial joints can be properly pivoted. Conversely, if the axis angle of a certain pivotal part of a component is too skewed, one of the pivotal parts may occur during assembly. After the pivoting is completed, the other pair of pivotal parts are unable or difficult to be coaxially aligned, or, although they can be barely engaged, the pivotal force is biased to affect the smooth operation and the life of the component; the conventional elliptical exercise machine (9) ) is perpendicular to each other between the front end of the guide arm (91) and the outer end of the crank arm (93) Pivotally connected, can be flexibly absorb deflection angle pivot portion, makes it easy to assemble, smooth operation. However, the connection structure is obviously too complicated and costly.
針對相同課題，台灣公告號362507及578578兩件專利分別揭露了不同型式的導引臂與曲柄臂之間的連接結構，各連接結構實質上都是透過相互垂直的二樞軸進行連接。在這兩件專利前案所例示的橢圓運動機中，導引臂的前端同樣是隨著曲柄臂的外端作繞圓運動，導引臂的後端同樣是沿著導軌作往復運動，但踏板是固設在導引臂的前、後二端之間，而非樞設；前述連接結構可以吸收導引臂前、後二端的樞接部位的角度偏斜。 For the same subject, Taiwan Patent Nos. 362507 and 578578 respectively disclose the connection structure between different types of guide arms and crank arms, and each connection structure is substantially connected through two pivots perpendicular to each other. In the elliptical exercise machine exemplified in the two patents, the front end of the guiding arm is also circularly moved with the outer end of the crank arm, and the rear end of the guiding arm also reciprocates along the guide rail, but The pedal is fixed between the front and rear ends of the guiding arm instead of being pivoted; the connecting structure can absorb the angular deflection of the pivoting portion of the front and rear ends of the guiding arm.
台灣公告號M324516專利揭露了另一種技術手段，也就是在導引臂與曲柄臂樞接的部位採用自調心軸承(self-aligning bearing)，使軸承自動順應樞接部位的角度偏斜進行修正。在這件專利前案所例示的橢圓運動機中，導引臂的另一端被一可前後擺盪的懸臂底端導引在一圓弧軌跡上運動，取代了直接在一有形導軌上滑動。 Taiwan Patent No. M324516 discloses another technical means, that is, a self-aligning bearing is used in a pivotal connection between the guiding arm and the crank arm, so that the bearing automatically conforms to the angular deflection of the pivoting portion for correction. . In the elliptical exercise machine exemplified in the prior patent, the other end of the guide arm is guided by a bottom end of the cantilever swinging on a circular arc path instead of sliding directly on a visible rail.

In addition, the material cost of the member is low, and the connection structure between the members is simple and simple, and the overall structure can be reduced. Production costs and increase production efficiency.
本發明的另一目的在於提供一種橢圓運動機，其利用生產容易、成本較低的簡單結構即可使各構件順暢地運作，而且比較不會因為組裝精度的問題而劣化或損壞。 Another object of the present invention is to provide an elliptical exercise machine which can smoothly operate components by a simple structure which is easy to manufacture and low in cost, and which is less deteriorated or damaged due to the problem of assembly accuracy.

The axial direction of the second pivot shaft corresponds to the left and right direction; the left and right pedals are respectively connected to the third portion of the two guiding arms; wherein When the first portion and the second portion of the guiding arm are respectively along the foregoing When a motion trajectory and a second motion trajectory move, the third portion of the guiding arm moves along a closed trajectory with respect to the frame body; and is characterized in that: at least between the first portion and the second portion of each of the guiding arms The partial section forms an elongated plate portion extending along the longitudinal direction of the guiding arm, and the thickness direction of each of the elongated plate portions corresponds to the left-right direction; the elongated plate portion can produce a bending And a twisting deformation, the deformation causing a relative deflection between the first pivot on the first portion and the second pivot on the second portion, the relative deflection being represented by the first pivot and/or the aforementioned The left and right ends of the axis of the second pivot generate a relative displacement including the front-rear direction and the up-and-down direction.
藉由上揭技術手段，當前述第一導引機構(例如曲柄機構)與導引臂之間的第一樞軸，以及前述第二導引機構(例如導軌或懸臂)與導引臂之間的第二樞軸，二者的軸線角度存在偏差時，導引臂能夠藉由前述長形板片部的撓曲及扭曲變形而自動適應，所以，即使樞接部位的角度精度不高，也能直接透過一般的樞軸結構簡易樞接，因而構件製造及組裝容易，機能正常持久；其中，相較於傳統的金屬桿材(無論實心或空心)，導引臂採用長形板材還可降低材料成本。 By the above technical means, when the first guiding mechanism between the first guiding mechanism (for example, the crank mechanism) and the guiding arm, and the second guiding mechanism (such as the guide rail or cantilever) and the guiding arm The second pivot axis, when the axial angles of the two are deviated, the guiding arm can be automatically adapted by the flexing and twisting deformation of the elongated plate portion, so even if the angular accuracy of the pivoting portion is not high, It can be directly pivoted through the general pivot structure, so the components are easy to manufacture and assemble, and the function is normal and durable. Among them, compared with the traditional metal rod (solid or hollow), the guide arm can be reduced by the long plate. Material costs.

請參閱圖1至圖4，分別是本發明一較佳實施例的橢圓運動機(1)在同一狀態下的左後方立體圖、右前方立體圖、左視圖及後視圖。必須先聲明的是，本文中對於左右方向、上下方向及前後方向的表示，基本上是對應於橢圓運動機在供人使用的狀態下，就使用者而言的左右方向、上下方向及前後方向。除非有特別說明，否則下文中所記載的「左右方向」、「上下方向」及「前後方向」，都只是基本空間概念下的方向表述，並非嚴格對應於三維座標系統中的標準X軸、Y軸及Z軸。下文中將會經常出現的「YZ平面」用以簡單代表「面向正左方/正右方的鉛垂面」。同樣地，例如「運動軌跡在一YZ平面上，只有上下及前後方向的位移，沒有左右方向的位移」，只是概念性或宏觀性的描述，並非儀器精密測量的微觀結果。 1 to 4 are respectively a left rear perspective view, a right front perspective view, a left side view and a rear view of the elliptical exercise machine (1) in the same state according to a preferred embodiment of the present invention. It must be stated first that the representations of the left and right direction, the up and down direction, and the front and rear directions in this paper basically correspond to the left and right direction, the up and down direction, and the front and rear directions of the user in the state of being used by the elliptical exercise machine. . Unless otherwise specified, the "left and right direction", "up and down direction" and "front and rear direction" described below are only the direction representations under the basic space concept, and do not strictly correspond to the standard X-axis, Y in the three-dimensional coordinate system.

以上即為本發明一較佳實施例的橢圓運動機(1)的主要及重要結構說明。橢圓運動機(1)供人使用時，使用者將雙腳踩踏在左、右二踏板(50)上，施力使踏板(其前端與導引臂(40)樞接的部位)沿前述封閉軌跡循環運動，經由導引臂(40)驅動曲柄臂(20)循環繞轉及懸臂(30)前後擺盪，同時，基於連動臂(70)的牽動，擺臂(60)亦會前後擺動，而且各踏板(50)相對於對應 的導引臂(40)的角度會週期性變化。橢圓運動機(1)供人使用時的基本動作及其作動原理屬於先前技術，細節部分省略說明。 The above is the main and important structural description of the elliptical exercise machine (1) according to a preferred embodiment of the present invention. When the elliptical exercise machine (1) is used by a user, the user steps on both the left and right pedals (50), and applies force to close the pedal (the portion whose front end is pivotally connected to the guiding arm (40)) along the aforementioned The trajectory cyclic motion drives the crank arm (20) to rotate around the cantilever arm (20) and the cantilever (30) to swing back and forth via the guiding arm (40), and the swing arm (60) also swings back and forth based on the linkage of the linkage arm (70), and Each pedal (50) is corresponding to the corresponding The angle of the guiding arm (40) changes periodically. The basic motion of the elliptical exercise machine (1) for human use and its principle of operation belong to the prior art, and the detailed description is omitted.
請參閱圖9至圖12，理想上，各導引臂(40)前端與對應的曲柄臂(20)外端樞接的第一樞軸(45)的軸線(A1)、各導引臂(40)後端與對應的懸臂(30)底端樞接的第二樞軸(46)的軸線(A2)，以及各導引臂(40)前、後二端之間的第一軸筒部(41)與對應的踏板承座(51)樞接的第三樞軸(53)的軸線(A3)，最好是相互平行，更精確來說，最好都是標準的左右軸線(註：作為基準，我們可以將曲柄軸(22)的軸線(L1)訂為橢圓運動機(1)的X軸，亦即標準的左右軸線，並將垂直於曲柄軸(22)軸線(L1)的平面訂為YZ平面)；對於某些習知的橢圓運動機而言，唯有前述軸線(A1)(A2)(A3)均為標準或近乎標準的左右軸線時，導引臂的各部位才能分別沿著位在YZ平面上的運動軌跡順暢運動，並且在運動過程中依據各軸線相對於曲柄臂、懸臂、踏板/連動臂順暢偏轉。 Referring to FIG. 9 to FIG. 12, ideally, the front end of each guiding arm (40) is pivotally connected to the axis (A1) of the first pivot (45) of the corresponding outer end of the crank arm (20), and each guiding arm ( 40) an axis (A2) of the second pivot (46) pivotally connected to the bottom end of the corresponding cantilever (30), and a first barrel portion between the front and rear ends of each of the guiding arms (40) (41) The axis (A3) of the third pivot (53) pivotally coupled to the corresponding pedal shoe (51) is preferably parallel to each other, more precisely, preferably to the standard left and right axis (Note: As a reference, we can define the axis (L1) of the crankshaft (22) as the X-axis of the elliptical motion machine (1), that is, the standard left and right axis, and will be perpendicular to the plane of the crankshaft (22) axis (L1). For the conventional elliptical machine, only when the aforementioned axis (A1) (A2) (A3) is a standard or near-standard left and right axis, the parts of the guiding arm can be respectively The trajectory along the position in the YZ plane moves smoothly, and is smoothly deflected relative to the crank arm, the cantilever, and the pedal/linking arm according to each axis during the movement.
然而在實務上，導引臂(40)、曲柄臂(20)、懸臂(30)、踏板承座(51)上的各樞接部位(例如軸銷、軸筒、軸孔等)可能因為本身或相關部件的製造精度或組裝精度而存在或多或少的角度偏斜，舉例來說，就算曲柄臂(20)內端與架體(10)之間的樞接軸線(亦即曲柄軸(22)的軸線(L1))是一標準的左右軸線，但是曲柄臂(20)與曲柄軸(22)之間的組裝誤差，以及曲柄臂(20)本身的加工誤差等，都可能導致曲柄臂(20)外端用以與導引臂(40)前端樞接的樞接部位的軸線(A1)存在左、右二端一高一低，及/或一前一後的偏斜狀況(註：當曲柄臂(2)依其內端的軸線(L1)轉動時，曲柄臂(2)外端的軸線(A1)的偏斜狀況會跟著改變)；懸臂(30)底端用以與導引臂(40)後端樞接的樞接部位也是相同情況。藉由本發明的上揭結構，因為導引臂(40)的前述長形板片部(44)能夠順應樞接部位的軸線偏斜狀況產生對應的撓曲變形及/或扭曲變形，所以，即便第一樞軸(45)、第二樞軸(46)、第三樞軸(53)的軸線(A1)(A2)(A3)存在偏斜狀況，亦不會影響橢圓運動機(1)的組裝及運作。 However, in practice, the pivoting parts (such as the pin, the shaft, the shaft hole, etc.) on the guiding arm (40), the crank arm (20), the cantilever (30), and the pedal bearing (51) may be due to themselves. Or more or less angular deflection of the manufacturing precision or assembly accuracy of the relevant component, for example, even the pivot axis between the inner end of the crank arm (20) and the frame body (10) (ie, the crankshaft ( The axis (L1) of 22) is a standard left and right axis, but the assembly error between the crank arm (20) and the crankshaft (22), and the machining error of the crank arm (20) itself may cause the crank arm. (20) The axis (A1) of the pivotal portion of the outer end for pivotally connecting with the front end of the guiding arm (40) has a left and a right end, a high and a low, and/or a skewed condition of the front and rear (note) : When the crank arm (2) rotates according to the axis (L1) of its inner end, the deflection of the axis (A1) of the outer end of the crank arm (2) will change accordingly; the bottom end of the cantilever (30) is used for the guide arm (40) The same is true for the pivotal joint of the rear end pivot. According to the above-mentioned structure of the present invention, since the elongated plate portion (44) of the guiding arm (40) is capable of conforming to the deflection of the axis of the pivotal portion to generate corresponding flexural deformation and/or distortion, even The axis (A1) (A2) (A3) of the first pivot (45), the second pivot (46), and the third pivot (53) is deflected and does not affect the elliptical exercise machine (1). Assembly and operation.
詳而言之，如圖12及圖13所示，理想上，各前述軸線(A1)(A2)(A3)最好都是標準的左右軸線，各自垂直於YZ平面(圖中標示為YZp)；然而如前所述，實務上，前述軸線(A1)(A2)(A3)難免存在角度偏斜的狀況；請搭配參閱圖12A、12B及圖13A、13B，在此假定導引臂(40)的第一 軸筒部(41)的軸線(A3)及第二軸筒部(42)的軸線(A2)均為標準的左右軸線，相對地，導引臂(40)的前端與曲柄臂(20)外端相互樞接的軸線(A1)存在偏斜狀況，例如軸線(A1)的左端比右端偏前(參閱圖12A)、軸線(A1)的左端比右端偏後(參閱圖12B)、軸線(A1)的左端比右端偏上(參閱圖13A)、軸線(A1)的左端比右端偏下(參閱圖13B)，或是複合狀況(例如軸線(A1)的其中一端比另一端偏前且偏下，或偏前且偏上)；依據軸線(A1)的偏斜狀況，導引臂(40)的長形板片部(44)會產生對應的撓曲變形及/或扭曲變形，例如長形板片部(44)的前端相對於後端往右撓曲(參閱圖12A)、前端相對於後端往左撓曲(參閱圖12B)、前端的頂側相對於底側往右扭曲(參閱圖13A)、前端的頂側相對於底側往左扭曲(參閱圖13B)，或是複合狀況(例如，當軸線(A1)的左端比右端偏前且偏下時，長形板片部(44)的前端相對於後端往右撓曲，同時，長形板片部(44)前端的頂側相對於底側往左扭曲)。為了呈現上述原理，圖12A、12B、13A及13B略微誇張表現，實際的偏斜及變形可能不會如此明顯。 In detail, as shown in FIGS. 12 and 13, ideally, each of the aforementioned axes (A1) (A2) (A3) is preferably a standard left and right axis, each perpendicular to the YZ plane (indicated as YZp in the figure). However, as described above, in practice, the aforementioned axis (A1) (A2) (A3) is inevitably subject to angular deflection; please refer to FIGS. 12A, 12B and FIGS. 13A, 13B together, assuming that the guiding arm (40) )First The axis (A3) of the barrel portion (41) and the axis (A2) of the second barrel portion (42) are both standard left and right axes, and oppositely, the front end of the guiding arm (40) and the crank arm (20) The axis (A1) pivotally connected to each other has a skew condition, for example, the left end of the axis (A1) is offset from the right end (see FIG. 12A), and the left end of the axis (A1) is offset from the right end (see FIG. 12B), and the axis (A1) The left end is higher than the right end (see Figure 13A), the left end of the axis (A1) is lower than the right end (see Figure 13B), or the composite condition (for example, one end of the axis (A1) is more forward and lower than the other end) Or, depending on the deflection of the axis (A1), the elongated plate portion (44) of the guiding arm (40) may have a corresponding flexural deformation and/or distortion, such as an elongated shape. The front end of the plate portion (44) is deflected to the right with respect to the rear end (see Fig. 12A), the front end is deflected to the left with respect to the rear end (see Fig. 12B), and the top side of the front end is twisted to the right with respect to the bottom side (see Fig. 13A), the top side of the front end is twisted to the left with respect to the bottom side (see Fig. 13B), or the composite condition (for example, when the left end of the axis (A1) is offset from the front end and is lower than the right end, the elongated plate portion ( 44) the front end is opposite to the back end Deflection while the elongated plate portion (44) with respect to the top side of the front end of the bottom side of the left twist). To present the above principles, Figures 12A, 12B, 13A, and 13B are slightly exaggerated, and actual skew and distortion may not be so apparent.
讀者應當理解，雖然上面是以只有導引臂(40)前端的軸線(A1)存在偏斜進行說明，但在其他的狀況，例如導引臂(40)前端的軸線(A1)沒有偏斜，而是導引臂(40)後端的軸線(A2)存在偏斜，或者，導引臂(40)前端的軸線(A1)及後端的軸線(A2)同時偏斜而不平行時，長形板片部(44)也會產生對應的撓曲變形及/或扭曲變形，以順應導引臂(40)前端的軸線(A1)與後端的軸線(A2)不平行的狀況。 The reader should understand that although the above description is based on the fact that only the axis (A1) of the leading end of the guiding arm (40) is deflected, in other cases, for example, the axis (A1) of the leading end of the guiding arm (40) is not skewed, Rather, the axis (A2) of the rear end of the guiding arm (40) is skewed, or the axis (A1) of the leading end of the guiding arm (40) and the axis (A2) of the rear end are simultaneously skewed and not parallel, the elongated plate The sheet portion (44) also produces corresponding flexural deformation and/or distortion to conform to the condition that the axis (A1) of the leading end of the guiding arm (40) is not parallel to the axis (A2) of the rear end.
依據本發明的橢圓運動機的上位概念，以上揭橢圓運動機(1)為例，各導引臂(40)的前端形成一第一部位，各導引臂(40)的後端形成一第二部位，前述曲柄軸(22)及左、右二曲柄臂(20)構成一第一導引機構，前述第一導引機構設在架體(10)與左、右二導引臂(40)的第一部位之間，導引各導引臂(40)的第一部位相對於架體(10)沿一第一運動軌跡(T1)運動，相對地，前述左、右二懸臂(30)構成一第二導引機構，前述第二導引機構設在架體(10)與左、右二導引臂(40)的第二部位之間，導引各導引臂(40)的第二部位相對於架體(10)沿一第二運動軌跡(T2)運動；各導引臂(40)的用以與踏板(50)連接的部位(即第一軸筒部(41))形成一第三部位，當導引臂(40)的第一部位及第二部位分別沿第一運動軌跡(T1)及第二運動軌跡(T2)運動時，前述第三部位相對於架體(10)沿一封閉軌跡運動。 According to the upper concept of the elliptical exercise machine of the present invention, the elliptical exercise machine (1) is taken as an example, the front end of each guide arm (40) forms a first portion, and the rear end of each guide arm (40) forms a first In the two parts, the crank shaft (22) and the left and right crank arms (20) constitute a first guiding mechanism, and the first guiding mechanism is disposed on the frame body (10) and the left and right guiding arms (40). Between the first portions of the guide arm (40), the first portion of each of the guiding arms (40) is moved relative to the frame (10) along a first motion trajectory (T1), and the left and right second cantilever (30) Having a second guiding mechanism, the second guiding mechanism is disposed between the frame body (10) and the second portion of the left and right guiding arms (40) to guide the guiding arms (40) The second portion moves along a second movement trajectory (T2) with respect to the frame body (10); a portion of each of the guiding arms (40) for connecting with the pedal (50) (ie, the first shaft tube portion (41)) Forming a third portion, when the first portion and the second portion of the guiding arm (40) move along the first motion track (T1) and the second motion track (T2), respectively, the third portion is opposite to the frame body ( 10) Move along a closed trajectory.
基於所屬技術領域的通常知識，例如參酌諸多已商品化或已公開於專利文獻中的習知橢圓運動機，在本發明的橢圓運動機中，導引臂的第一部位的第一運動軌跡及第二部位的第二運動軌跡，通常其中一者為封閉軌跡(例如圓形、橢圓形、卵形或類似形狀的軌跡)，可用曲柄機構或搭配連桿機構進行導引，另一者為往復軌跡(例如直線或弧線軌跡)，可用導軌或懸臂進行導引。當然，也有可能第一運動軌跡及第二運動軌跡都是封閉軌跡，使導引臂的第三部位產生所需的運動軌跡。此外，依據實施選擇，導引臂的第三部位可能介於第一部位與第二部位之間(如同上揭較佳實施例)，也可能在不在第一部位與第二部位之間，例如，導引臂的前端形成第一部位並沿一圓形軌跡運動，導引臂的前、後二端之間形成第二部位並沿一直線或弧線軌跡運動，而導引臂的後端形成第三部位，導引踏板沿一類似橢圓形的封閉軌跡運動。再者，導引臂的第一、第二、第三部位未必呈現前後排列，亦有可能呈現上下排列，例如，導引臂具有一頂端及一底端，前述頂端形成第一部位並沿一圓形軌跡運動，前述頂端及底端之間形成第二部位並沿一直線或弧線軌跡運動，前述底端形成第三部位，導引踏板沿一類似橢圓形的封閉軌跡運動。 Based on the general knowledge in the art, for example, a plurality of conventional elliptical exercise machines that have been commercialized or disclosed in the patent literature, in the elliptical exercise machine of the present invention, the first motion trajectory of the first portion of the guiding arm and The second motion trajectory of the second portion, usually one of which is a closed trajectory (for example, a circular, elliptical, oval or similarly shaped trajectory), can be guided by a crank mechanism or with a link mechanism, and the other is reciprocating Tracks (such as straight or curved tracks) can be guided by rails or cantilevers. Of course, it is also possible that the first motion trajectory and the second motion trajectory are closed trajectories, so that the third portion of the guiding arm produces a desired motion trajectory. In addition, depending on the implementation option, the third portion of the guiding arm may be between the first portion and the second portion (as in the preferred embodiment above), or may not be between the first portion and the second portion, for example The front end of the guiding arm forms a first portion and moves along a circular path. A second portion is formed between the front and rear ends of the guiding arm and moves along a straight line or an arc track, and the rear end of the guiding arm forms a first In three parts, the guide pedal moves along a closed ellipsoid like an ellipse. Furthermore, the first, second, and third portions of the guiding arm are not necessarily arranged in front and rear, and may be arranged in an upper and lower arrangement. For example, the guiding arm has a top end and a bottom end, and the top end forms a first portion and is along a The circular path moves, and the second portion is formed between the top end and the bottom end and moves along a straight line or an arc track. The bottom end forms a third portion, and the guiding pedal moves along a closed elliptical-like trajectory.
本發明的技術特徵之一，是令導引臂的第一部位與第二部位之間具有一沿導引臂的長度方向延伸且板厚方向對應於左右方向的長形板片部，前述長形板片部能夠產生撓曲及扭曲變形，前述變形會使前述第一部位上的樞軸與前述第二部位上的樞軸產生相對偏轉，前述相對偏轉表現為至少一前述樞軸的軸線二端產生包含前後方向及上下方向的相對位移；換個觀點來說，當前述第一導引機構或第二導引機構與導引臂之間的樞軸存在偏斜狀況，亦即樞軸的軸線二端一高一低，及/或一前一後時，前述長形板片部會順應軸線偏斜狀況產生對應的撓曲變形及/或扭曲變形。 One of the technical features of the present invention is that the first portion and the second portion of the guiding arm have an elongated plate portion extending in the longitudinal direction of the guiding arm and the thickness direction corresponding to the left and right direction, the length The slab portion is capable of flexing and twisting, the deformation causing a relative deflection of the pivot at the first portion and the pivot at the second portion, the relative deflection being represented by at least one axis of the aforementioned pivot axis The end generates a relative displacement including the front-rear direction and the up-and-down direction; in another aspect, when the pivotal relationship between the first guiding mechanism or the second guiding mechanism and the guiding arm is skewed, that is, the axis of the pivot When the two ends are one high, one low, and/or one after the other, the long plate portion will have corresponding flexural deformation and/or distortion deformation in accordance with the axis deflection condition.
在本發明中，長形板片部的板厚方向必須對應於左右方向，亦即相對二板面分別朝向左方及右方，才能利用其撓曲及扭曲變形順應(軸線基本上對應於左右方向的)前述樞軸的各種偏斜狀況，如圖12A、12B、13A、13B示意；反過來說，假設長形板片部的板厚方向對應於上下方向，亦即相對二板面分別朝向上方及下方，則當前述樞軸的軸線二端呈現一前一後時，長形板片部的撓曲或扭曲變形並無法對其作出補償。 In the present invention, the direction of the thickness of the elongated plate portion must correspond to the left and right direction, that is, the opposite sides of the two plates face to the left and right, respectively, in order to be adapted by the deflection and the distortion (the axis substantially corresponds to the left and right The various deflection states of the aforementioned pivot are illustrated in FIGS. 12A, 12B, 13A, and 13B; conversely, it is assumed that the thickness direction of the elongated plate portion corresponds to the up and down direction, that is, the opposite faces of the two plates are respectively oriented. Above and below, when the two ends of the axis of the aforementioned pivot are presented one after the other, the deflection or distortion of the elongated plate portion cannot be compensated for.
在上揭較佳實施例中，各前述連動臂(70)整體形成長形板片狀，而且板厚方向同樣是對應於左右方向，基於相同的原理，當連動臂(70)前端與前述擺臂(60)底端樞接的軸線，以及連動臂(70)後端與前述導引臂(40)樞接的軸線(亦即第一軸筒部(41)的軸線)，其中至少一者存在偏斜狀況，或總之二者不平行時，連動臂(70)亦會產生對應的撓曲變形及/或扭曲變形。 In the above preferred embodiment, each of the linkage arms (70) is integrally formed into an elongated plate shape, and the plate thickness direction also corresponds to the left and right direction, based on the same principle, when the front end of the linkage arm (70) and the aforementioned pendulum An axis pivoted at a bottom end of the arm (60), and an axis at which a rear end of the linking arm (70) is pivotally coupled to the guiding arm (40) (ie, an axis of the first barrel portion (41)), at least one of which When there is a skew condition, or the two are not parallel, the interlocking arm (70) will also produce corresponding flexural deformation and/or distortion.
本發明中的導引臂的長形板片部可能由導引臂的其中一端完整延伸至另一端，或者說，導引臂的第一、第二及第三部位，任二部位之間均可藉由長形板片部的撓曲及扭曲變形而相對偏轉。依據實施選擇，本發明的橢圓運動機可能沒有連動臂、擺臂及其等效機構，同時，踏板是直接設在導引臂的第三部位，踏板相對於導引臂不會偏轉。 The elongated plate portion of the guiding arm of the present invention may extend completely from one end of the guiding arm to the other end, or the first, second and third portions of the guiding arm, between any two parts The deflection can be relatively deflected by the deflection and distortion of the elongated plate portion. Depending on the implementation options, the elliptical exercise machine of the present invention may not have a linkage arm, a swing arm, and its equivalent mechanism. At the same time, the pedal is directly disposed at the third portion of the guide arm, and the pedal is not deflected relative to the guide arm.
藉由本發明提供的技術手段，橢圓運動機的導引臂等構件即使樞接部位的角度精度不高，也能直接透過一般的樞軸結構簡易樞接，此外，相較於傳統的金屬桿材(無論實心或空心)，本發明中的導引臂因採用長形板材故材料成本較低，所以，本發明可以降低橢圓運動機的生產成本、提高橢圓運動機的生產效率。另一方面，本發明的橢圓運動機利用生產容易、成本較低的簡單結構即可使各構件順暢地運作，而且比較不會因為組裝精度的問題而劣化或損壞。 According to the technical means provided by the present invention, the member such as the guiding arm of the elliptical exercise machine can be directly pivoted directly through the general pivot structure even if the angular accuracy of the pivotal portion is not high, and in addition, compared with the conventional metal rod (Whether solid or hollow), the guide arm of the present invention has a lower material cost due to the use of a long plate, so that the present invention can reduce the production cost of the elliptical exercise machine and increase the production efficiency of the elliptical exercise machine. On the other hand, the elliptical exercise machine of the present invention can smoothly operate the members by using a simple structure which is easy to manufacture and low in cost, and is less deteriorated or damaged due to the problem of assembly accuracy.
