[Prior Art] 1 Elliptical machine is a kind of sports fitness equipment that has emerged in recent years. Generally speaking, it can guide the left and right two jaws to move along an approximately elliptical trajectory, so that users can simulate walking and running. A device that moves to the legs and so on. For example, U.S. Patent No. 6,390,954 discloses an elliptical machine structure. Briefly, it is provided with a crank mechanism at the front end of the body and a left and right guide at the rear end of the frame. Rail; each of the left and right sides has a support 4 stems. Each of the tower poles pivots its front end to one of the crank arms of the crank mechanism so that it can be rotated along a circular track and a roller is pivoted at the rear end. It can slide back and forth on the corresponding rails. At the same time, the top surface of the middle part of the support rod is provided with a pedal for pedaling. In addition, the front end of the frame body is provided with left and right swing arms, so that the top end of the swing arm forms a The movable grip connects a link between the bottom end and the corresponding support rod so as to be mutually movable. Thereby, the left and right pedals can be circulated on an approximately elliptical closed trajectory, and the left and right grips can also perform a yaw motion in cooperation with the pedal. The above-mentioned elliptical machine has the following disadvantages: 1. The pedal movement has a different length (in order to satisfy the basic leg movement stroke), and the guide rail at the rear end of the frame is later than the pedal's range of motion. Extending a distance from the mouth, the length of the elliptical machine in the front and rear axial direction is quite long. When it is used in the indoor environment of 1288008, it needs to be relatively large (should occupy space. 2. Because the pedal is fixedly installed in the branch p On the 'thus, the angle change of the pedal itself when it is circulated' is the angle change corresponding to the front and rear ends of the support rod. In this form, the relative angle of the toe and the heel of the user during the movement or The force application area is not consistent with the actual walking and running patterns. Ideally, when the step _ position is at the bottom of the trajectory (corresponding to the actual walking, the bottom of the foot when running), the tread surface should approach Horizontal, while in other sections of the obedience (corresponding to lifting legs, stepping on), the front end of the tread surface should be lower than the subsequent 'and the lower inclination is most obvious at the highest point. Compared with the basic body type of the previous case, Patent No. 6, pp. 7,462 discloses an elliptical machine with a simple structure and a small size. It is mainly provided with a crank mechanism at the rear end of a body, and a left and right swing arm is pivoted at the front end of the frame body. A swing is connected between the bottom end of each swing arm and the crank arm of the same side, and a pedal is arranged on each branch pole, whereby the left and right pedals can be along the approximately elliptical closed rail Track movement. Although the front and rear elliptical machine has a short front and rear length and a small footprint, it is suitable for use in homes and other spaces. However, the foot movement provided by it is still not ergonomic. When the (4) pedal is at the bottom of the trajectory, the end will be south to the rear end and assume an up-and-down posture, which is inconsistent with the actual walking, the landing stage when running, and the shape of the foot flat on the ground. SUMMARY OF THE INVENTION The main object of the present invention is to provide an elliptical machine which can provide a sufficient length of foot movement stroke and a more ergonomic pedal motion l288〇fjg mode, and the elliptical machine has a short front and rear length. , floor space and space In order to achieve the foregoing objectives, the elliptical machine provided by the present invention comprises: 'a frame body which can be mounted on the 'surface, the rear half is provided with a guide rail which is close to the ground and extends forward and backward; a mechanism (for example, a crank mechanism) The front half of the frame body has a relatively two-way wrap point that can move on a circular track; a flywheel pivoted in the front half of the frame body can be driven with the two-way wrap point; The right second support falls, the front ends of the two support rods are respectively pivotally connected to the two-way wrap-around point, and the rear end can move the guide rail between a front turn-back point and a rear turn-back point, so that the front end; a support portion is movable on a closed curved path of the arc; the left and right swing arms each have a pivotal portion pivotally connected to the front half of the frame body, and a swinging position below the pivotal portion The left and right two links respectively pivotally connect the front end to the swinging end of the corresponding swing arm; the left and right two pedals are respectively coupled with the rear ends of the two links, and are located at the corresponding support of the support rod The rear portion of the portion is in a relative pivotal relationship with the support portion. Wherein the height difference between the bottom edge of the circular track P and the guide is less than 丨〇 cm; the length of the connecting line at the front and rear ends of the support bar is between the diameter of the circular track and twice the diameter, the support portion Is located behind the midpoint of the length of the support rod; the leading edge of the closed trajectory is no more than the rear edge of the circular trajectory and the front and rear water raft spacing of the two is less than 20 cm; The point is no more forward than the leading edge of the front end motion track of the pedal, and the rear turnback point i on the guide rail is no more rearward than the trailing edge of the pedal rear end motion track.

I 端，各曲柄臂（32)鉍外端形成一迴繞接點（34)，如此產生 可在一圓形軌跡（R)上維持180度相對的二迴繞接點 (34)(參閱第四圖）。前述圓形軌跡（r)的底緣十分接近地 1288008 面，換言之，如第五圖所示，當曲柄臂（32)旋轉成朝向正 下方時，外端會非龠靠近地面（或底座（2U)，具體而言， 其間的高度差距在ίο公分以内。大皮帶輪（33)是同軸固 接在曲柄軸（31)上，位在左、右二曲柄臂（32)之間。 迴繞機構（30)的上方另外設有一飛輪（4〇)，飛輪（4〇) 也疋依左右轴向柩設在設置架（22)上，它的直徑小於前述 形軌跡（R)的直徑，而且後緣比圓形軌跡（11)的後緣更 靠前方，換言之，戒輪（40)是位在曲柄臂（犯）活動範圍的 前後邊界之間（參閱第四圖）。飛輪（40)的左侧面同軸固接 一小皮帶輪（41)，小皮帶輪（41)位在迴繞機構（30)的大皮 帶輪（33)正上方，二者（4卜33)之間環套一傳動皮帶（42), 使得飛輪（40)與迴轉機構（30)能以預定速比相互帶動旋 轉。 此外’飛輪（40)旁邊設有一習知的「渦電流制動器 (eddy-current brake ; ECB)」（圖中未示），如同現今運 動器材經常採用的方式，前述渦電流制動器具有一可活動 的磁力組件，使用者可透過立桿（23)頂端的控制台（50)以 電控方式控制前述磁力組件相對於飛輪（4〇)的位置關 係，藉此調整飛輪（40)的旋轉阻力。 ’ 如第一圖及第四圖所示，設置架（22)的周圍設有一殼 體（10)，它完整包覆前述迴繞機構（30)、飛輪（4〇)、渦電 流制動器及其相關電路，藉以保護該等機構及使用者安 全。殼體（10)前、後二侧的殼板十分靠近前述圓形軌跡（R) 的前緣及後緣（參閱第四圖），而且後侧殼板上設有左右併 1288008 列的二縱向穿槽（11)。 架體（2G)的底座（21)具有沿前後轴向延伸的左、右二 、幸干（24) ’各松桿（24)的後半段頂面設有一長條凹窪狀的 •導軌(25)。迴繞機f (3〇)的左、右二曲柄臂⑽外端（即迴 % =點（34))分別支撐桿（6Q)連接，各支撐桿(6〇)是將 其前端依左右轴向_接在曲柄臂（32)的外端外側面，桿身 穿f殼體⑽的縱向穿槽（11)，後端樞設-滾輪（⑴，以 可前後滾動的方式_壓在對應侧邊的導軌（25)上。如此， . 當支撐桿（60)前端举前述圓形執跡（R)繞轉時，後端即會 對應地沿著導軌（2$)在一前折返點（26)及一後折返點（27) 之間往復位移（參閱第二圖），而且，由於左、右二支撐桿 (_〇)的前端在圓形軌跡（R)上維持ι8〇度相對，所以二者 的後端會呈現反向位移。 各支撐桿（60)，、後二端之間的連結線長度，是適度 大於前述圓形轨跡（R)的直徑，並且小於圓形軌跡（R)直 徑的兩倍。各支撐桿（60)的長度中間點偏後方位置設有一 & 支撐部（62)，具體而言是一往上凸伸的U形彎板，具有左 右相對的二壁片（63)(參閱第六圖）。由於支撐桿（6〇)的 i 前、後二端分別受限於前述繞圓運動及直線往復運動，因 此支撐部（62)是沿—近似橢圓形的封閉轨跡（c )循環運動 (參閱第四、五圖）ί。前述「橢圓形」封閉轨跡（C)的長軸 大致對應於前後軸向，而短轴大致對應於上下軸向。在前 後軸向上，前述封南軌跡（C )的前緣十分接近前述圓形軌 跡（R)的後緣，具體而言，二者（C、R)的前後水平間距 1288008 在2〇公分以内，當支撐部（62)移至活動範圍的最前方時 (例如第四圖中的左側支撐部），會非常靠近殼體（10)的後 側殼板。 左、右二支撐桿(60)上分別設有一踏板（70)，用以供 使用者雙腳踩站，i踏板（7〇)具有一對應使用者腳尖的前 端及一對應使用者腳跟的後端，並且將前端依左右軸向樞 接在支樓桿（60)的支撐部（62)左右二壁片（63)之間，使得 踏板（70)前端可被運動中的支撐桿（6〇)導引而沿前述封閉 軌跡（C)運動，而具踏板（7())整體可相對於支撐桿（6〇)上 下偏轉。 架體（20)前半部的左、右二侧各設有一擺臂（8〇)，各 擺臂（80)大致呈縱向彎延，並且將它中央區段的一樞接部 (81)依左右軸向樞接在架體（2〇)的立桿（22)側邊，使得底 端形成一可前後擺盪的擺盪端（82)。此外，各擺臂（8〇)的 頂端形成一用以供使用者捉握的活動握把（83)。 左、右二擺臂（80)的擺盪端（82)分別與一連桿（90)連 接’各連桿（90)是將其前端依左右軸向樞接在擺臂的 擺蘯^&(82) ’因而被限制在一弧線執跡上運動’連桿（g〇) 後端則固捧在對應侧邊的踏板（70)外側面。藉此，支撐桿 (60)與擺臂（80)會經由連桿(9〇)相互帶動，而且，連桿（90) 活動時相對於支撐桿（60)及地面的角度變化，會帶動踏板 (70)相對於支撐桿（60)及地面產生相同的角度變化。 使用上述橢圓機（1)時，使用者將雙腳踩站在左、右 二踏板（70)上，並以雙手握住左、右二握把(83)，當雙腳 11 1288008 及雙手施力使踏板（了0)及握把（83)各自沿運動軌跡運動 時，透過支撐桿（60)、迴繞機構（30)、連桿（gQ)及擺臂（8〇) 的連結帶動’左、古二踏板（70)會保持相對在一近似橢圓 形的軌跡上運動（註：詳而言之，踏板前端係沿前述封閉 軌跡（C )，而後端係沿另一近似橢圓形的封閉軌跡運 ^ j 動），左、右一握把（83)也會彼此反向地在一弧線軌跡上 刖後往復位移，而具，同一侧邊的握把（83)及踏板（7〇)是 呈現反向運動，使用者可藉此進行全身的協調運動。當 滅’使用者也可選擇將雙手捉握在立桿（23)頂端預設的固 定扶手（28)上，僅“行下半身運動。 使用者可以透過前述控制台（50)調整飛輪（4〇)的旋轉 阻力（或是設定阻力的時序變化），連帶改變踏板（γ〇)及握 把（83)的運動阻力，藉以得到不同的運動難易度。 f 在運動過程中，當踏板（70)位在運動轨跡的底部、後 部區段時（例如第五圖當中的左腳踏板或第四圖當中的右 腳踏板），其頂面（腳踏面）大致呈現水平狀態；而當踏板 (70)位在運動軌跡的其他區段時，腳踏面的前端低於後 端，並且在軌跡的頂部時（例如第五圖當中的右腳踏板）， 下斜最為明顯。上述踏板角度變化與人體走路、跑步時的 腳掌角度較為吻合，亦即，在著地時腳底會平貼於地，而 在抬腿、踩下時會是腳尖朝下，如此，使用者在利用本發 明的橢圓機（1)進行腿部運動時會比較舒適自然，也比較 不容易產生酸疼或運動傷害。 由第四圖及第五圖可清楚看出，基於預設的構件比例 12 1288008 及二間關係，各支撐桿（60)的後端是保持在對應的踏板 (70)正下方，亦即，支撐桿（6〇)後端在前後軸向上的位置， 始終介於當時的踏板(7〇)前、後二端之間。前已述及，各 未撐柃（60)的後端是在導軌（25)上的一前折返點（26)及一 後折返點（27)之間活動（參閱第二圖），換句話說，該前折 返點（26)不會比踏板（70)前端的運動轨跡（即封閉軌跡 (c))的刖緣更罪前方，該後折返點（27)不會比踏板（別）後 端的運動軌跡（圖中未示）的後緣更靠後方。 此外’如第四P所示，擺臂（80)樞接在架體（20)上的. 位置（即樞接部（81)所在位置），大致是位在迴繞機構（3〇) 的曲柄軸（31)(即碑述圓形軌跡（r)的圓心）正上方，而 且，擺臂（80)的擺i端（82)弧線軌跡的最前端，亦大致與 前述圓形軌跡（R)的前緣切齊（參閱第四圖）。在實施上， 前述弧線軌跡的最前端以不超過該圓形軌跡前緣1〇公分 為佳。因此，擺臂（80)底端擺至最前方時，並不會往前超 出殼體（10)。擺臂（80)頂端的握把（83)同樣不會往前超出 殼體（10)。 經由圖面及以上說明可知，本發明上揭橢圓機（i)在 前後轴向上的長度，大體而言就是「曲柄臂（32)活動範圍 的前後長度」加上「踏板（70)活動範圍的前後長度」。因 此，與一般的習用橢圓機相較，本發明的橢圓機（1)能在 保有足夠的踏板行释及良好的人體工學之下，有效縮減器 材的佔地面積及佔置空間（特別是體現在前後長度方 面）。如此，對於室内空間較受限制的家庭使用者而言， 13 1288008 即可較輕易地將器材擺設在室内角落，或是相對騰出較寬 裕的活動空間，而立在搬運移動時也比較不受阻礙。同樣 ，，對於追求空關料的販售業者或健身中心業者而 s，亦可藉此在相帛面積内陳列更多的運動器材。對製造 气而。尺寸短縮除了可以提高倉儲密度，更重要地當鈥 是可以節省材料、包裝成本，並反應至產品售價。 接著請再參閱弟七圖至第九圖的本發明另一較佳實 施例的橢圓機⑵，本實施例同樣可達成節省佔置空間等 上述優點’其構件組成及空間、尺寸關係亦與上揭實施例 大致相同，以下僅就特殊差異部分進行說明。（註：本實 施例當中與前一實施例對應的構件或部位，代表符號均採 用對應5虎碼附加「辦號（’）」。） 如圖所示，本實施例當中的迴繞機構（3〇，）具有左、 右相對的二骨架（35)，各骨架（35)呈十字形，其中一分支 (形同曲柄臂）的外端作為迴繞接點（34，）。架體（2〇，）前端 同樣a又有包覆迴繞機構（3〇’）的殼體（i〇,），但殼體（1〇,）的 左、右二侧面各有一對應十字形骨架（35)的圓形開口 (12) ，並在開口（12)部位封補一與骨架（35)固接的圓盤 (13) 。各支撐桿（6(Τ )的前端位在圓盤（13)外侧，利用一橫 穿圓盤（13)的樞轴與該迴繞接點（34,）形成樞接，可牽動骨 架（35)及圓盤（13) —同旋轉。與前例相較，本實施例的殼 體（10’）左右寬度較窄。 架體（20，）的底座後端同樣設有前後延伸的左、右二 導軌（25，），該二導軌（2S，）是位在一箱形護蓋（28)的相對 1288008 二侧，導軌（25，）上方受該護蓋（28)遮蔽（註：第八圖中將 護蓋局部取除）。各支撐桿（60，）的後端位在護蓋（28)外 侧，以一輪軸（64)亨過護蓋（28)侧面的長槽孔（29)而與滾 輪（6Γ)樞接，使得在導軌（25，）上滾動的滚輪（61，）可受到 護蓋（28)防護，較4安全。： 與前例相較，丰實施例中的飛輪（40，）相對較小，而 且位置低於迴繞，構（30，）（本例是設在接近地面的高 度），如此可將殼體（10，）的高度降低至貼近迴繞機構 (30，）。此外，殼體(1〇，）内部增加樞設一中介輪組（45), 該中介輪組（35)是由一大徑輪及一小徑輪同軸組成，迴繞 機構（30，）的大皮帶輪（33，）先與該中介輪組（45)的小徑輪 以一皮帶環套連結（圖中未示），而中介輪組（45)的大徑輪 再與飛輪（40，）的小皮帶輪（41，）以另一皮帶環套遠姓 中未示），藉此在有限空間内達成預定速比的傳動。^田 在前一實施例中，踏板（70)是直接樞接在支撐桿（6〇) 上，而連桿（90)則不與支撐桿（60)直接樞接（但也間接透過 踏板（7〇)形成相對樞接關係）。在本實施例中，踏板） 同樣是將其前端樞接在支撐桿（60，）的支撐部（62，）上，不 同的是，連桿⑽’）的對應部位也依同_軸心樞接在該支 揮部（62’），而且連捍（90’）後端往内彎折至踏板（7〇,）底部 (參閲第七圖；圖申取除踏板（7〇，）的局部構件），由正下 ^拖住踏板（7〇，）並與其固接，使踏板（7〇，）相對於支推桿 (60’）的轴樞結構更為均衡穩定。 本實施例其他未加詳述的部分，特別是構件及部件運 15 1288008 動軌跡彼此之間的相對位置、距離、尺寸比例等全部同 兮刖-實施例，此處不再贅述。本實施例的橢圓機⑵同 樣可在保有足夠的踏板行程及良好的人體工學之下，有效 縮減器材的佔地面積及佔置空間。與前例相：，本實施例 的殼體（10，）高度更低、左右寬度更窄。At the I end, the outer end of each crank arm (32) forms a wrap-around joint (34), thus creating a two-way wrap (34) that maintains 180 degrees relative to a circular path (R) (see Figure 4). ). The bottom edge of the circular track (r) is very close to the 1288008 face. In other words, as shown in the fifth figure, when the crank arm (32) is rotated directly downward, the outer end will be close to the ground (or the base (2U). Specifically, the height difference between them is within ίο cm. The large pulley (33) is coaxially fixed on the crankshaft (31) and is located between the left and right crank arms (32). A flywheel (4〇) is additionally arranged on the upper side, and the flywheel (4〇) is also disposed on the installation frame (22) according to the left and right axial directions, and its diameter is smaller than the diameter of the aforementioned shape track (R), and the trailing edge ratio is The trailing edge of the circular trajectory (11) is more forward, in other words, the wheel (40) is located between the front and rear boundaries of the crank arm (see figure 4). The left side of the flywheel (40) The surface is coaxially fixed to a small pulley (41), and the small pulley (41) is located directly above the large pulley (33) of the rewinding mechanism (30), and a transmission belt (42) is looped between the two (4, 33). The flywheel (40) and the slewing mechanism (30) can be rotated relative to each other at a predetermined speed ratio. Further, a flywheel (40) is provided with a side Known as "eddy-current brake (ECB)" (not shown), as is often the case with today's sports equipment, the eddy current brake has a movable magnetic component that the user can pass through the pole ( 23) The console (50) at the top controls the positional relationship of the aforementioned magnetic component with respect to the flywheel (4〇) in an electronically controlled manner, thereby adjusting the rotational resistance of the flywheel (40). As shown in the first and fourth figures A casing (10) is disposed around the installation frame (22), which completely covers the rewinding mechanism (30), the flywheel (4 〇), the eddy current brake and related circuits, thereby protecting the safety of the mechanism and the user. The front and rear sides of the casing (10) are very close to the leading and trailing edges of the circular track (R) (see the fourth figure), and the rear side panels are provided with two sides and two 1288008 columns. Longitudinal groove (11). The base (21) of the frame body (2G) has left and right sides extending in the axial direction of the front and rear, and the front part of the second half of each of the loose rods (24) is provided with a long strip. Concave-shaped • Guide rail (25). Left and right two crank arms (10) of rewinding machine f (3〇) The outer end (ie, back % = point (34)) is respectively connected to the support rod (6Q), and each support rod (6〇) is connected to the outer side of the outer end of the crank arm (32) by the front end of the support rod (6〇). Wearing a longitudinal slot (11) of the f-shell (10), the rear-end pivot-roller ((1) is pressed back and forth on the guide rail (25) of the corresponding side. Thus, when the support rod (60) When the front end lifts the aforementioned circular trace (R), the rear end is correspondingly reciprocally displaced along the guide rail (2$) between a front turnback point (26) and a rear turnback point (27) (see The second figure), and, since the front ends of the left and right support bars (_〇) maintain ι8 相对 relative on the circular trajectory (R), the rear ends of the two will exhibit reverse displacement. The length of the connecting line between each of the support bars (60) and the rear ends is moderately larger than the diameter of the circular track (R) and less than twice the diameter of the circular track (R). A support portion (62) is provided at a position opposite to the intermediate point of the length of each support rod (60), in particular, a U-shaped curved plate that protrudes upward, and has two wall plates (63) opposite to each other (see Figure 6). Since the front and rear ends of the support rod (6〇) are respectively limited by the aforementioned circular motion and linear reciprocating motion, the support portion (62) is cyclically moved along the closed elliptical closed path (c) (see Fourth and fifth figures) ί. The long axis of the aforementioned "elliptical" closed trajectory (C) substantially corresponds to the front and rear axial directions, and the short axis corresponds to the upper and lower axial directions. In the front and rear axial directions, the leading edge of the aforementioned south trajectory (C) is very close to the trailing edge of the circular trajectory (R). Specifically, the front and rear horizontal spacing of the two (C, R) is 128008 within 2 〇 cm. When the support portion (62) is moved to the forefront of the range of motion (for example, the left side support portion in the fourth figure), it is very close to the rear side panel of the casing (10). Each of the left and right support rods (60) is provided with a pedal (70) for the user to step on the foot. The i pedal (7〇) has a front end corresponding to the user's toe and a corresponding user's heel. End, and the front end is pivotally connected between the left and right wall sheets (63) of the support portion (62) of the branch pole (60) according to the left and right axial direction, so that the front end of the pedal (70) can be supported by the moving rod (6〇) Guided to move along the aforementioned closed trajectory (C), and the pedal (7()) as a whole can be deflected up and down with respect to the support rod (6 〇). The left and right sides of the front half of the frame body (20) are respectively provided with a swing arm (8〇), and each swing arm (80) is substantially longitudinally bent, and a pivotal portion (81) of the central section thereof is The left and right axial directions are pivotally connected to the side of the upright (22) of the frame body (2〇), so that the bottom end forms a swinging end (82) which can swing forward and backward. In addition, the top end of each swing arm (8 〇) forms a movable grip (83) for the user to grasp. The swinging ends (82) of the left and right swing arms (80) are respectively connected with a connecting rod (90). Each connecting rod (90) is a swinging arm pivoting its front end to the swing arm in the left and right axial direction. (82) 'Therefore it is restricted to move on an arc track' link (g〇) The rear end holds the outer side of the pedal (70) on the corresponding side. Thereby, the support rod (60) and the swing arm (80) are mutually driven via the connecting rod (9〇), and the angle of the connecting rod (90) relative to the support rod (60) and the ground changes, which will drive the pedal (70) The same angular change is produced with respect to the support rod (60) and the ground. When using the above elliptical machine (1), the user steps on both the left and right pedals (70) and holds the left and right grips (83) with both hands, when the feet 11 1288008 and the pair When the hand applies force to move the pedal (0) and the grip (83) along the movement path, the connection between the support rod (60), the rewind mechanism (30), the connecting rod (gQ) and the swing arm (8〇) is driven. The left and second pedals (70) will remain in motion relative to an approximately elliptical trajectory (note: in detail, the front end of the pedal is along the aforementioned closed trajectory (C), while the rear end is along another approximately elliptical shape. The closed trajectory moves, and the left and right grips (83) are also reciprocally displaced on the arc track in opposite directions to each other, and the grips (83) and pedals on the same side (7) It is a reverse motion that allows the user to perform coordinated movements throughout the body. When the user is off, the user can also choose to hold both hands on the fixed armrest (28) preset on the top of the upright (23), only to move the lower body. The user can adjust the flywheel through the console (50).旋转) The rotational resistance (or the timing change of the set resistance), together with the resistance of the pedal (γ〇) and the grip (83), to obtain different degrees of exercise difficulty. f During the exercise, when the pedal (70 When the bottom of the motion track is in the bottom section and the rear section (for example, the left foot pedal in the fifth figure or the right foot pedal in the fourth figure), the top surface (the tread surface) is substantially horizontal; When the pedal (70) is in the other section of the motion track, the front end of the foot surface is lower than the rear end, and at the top of the track (for example, the right foot pedal in the fifth figure), the lower slope is most noticeable. The change of the pedal angle is consistent with the angle of the foot when the human body walks and runs, that is, the sole of the foot will be flat on the ground when the ground is approached, and the toes will face downward when the leg is lifted or stepped on, so that the user is using the present The elliptical machine (1) of the invention will perform a leg movement. It is more comfortable and natural, and it is less prone to aching or sports injury. It can be clearly seen from the fourth and fifth figures that the rear end of each support rod (60) is based on the preset component ratio 12 1288008 and the relationship between the two. It is kept directly below the corresponding pedal (70), that is, the rear end of the support rod (6〇) is in the front and rear axial direction, always between the front and rear ends of the pedal (7〇) at that time. As mentioned, the rear end of each unsupported (60) is movable between a front turn-back point (26) and a rear turn-back point (27) on the guide rail (25) (in other words, see second figure), in other words, The front turnback point (26) is not more sinful than the rim of the trajectory of the front end of the pedal (70) (ie, the closed trajectory (c)), and the rear turnback point (27) is not more than the rear end of the pedal (other) The trailing edge of the motion trajectory (not shown) is further rearward. Further, as shown in the fourth P, the swing arm (80) is pivotally connected to the frame body (20) (ie, the pivoting portion (81) is located Position) is roughly located directly above the crankshaft (31) of the rewinding mechanism (3〇) (ie, the center of the circular path (r) of the inscription), and the pendulum end of the swing arm (80) (8) 2) The foremost end of the arc track is also substantially aligned with the leading edge of the circular track (R) (see the fourth figure). In practice, the front end of the arc track does not exceed the leading edge of the circular track 1 The 〇 is divided into good. Therefore, when the bottom end of the swing arm (80) swings to the foremost position, it does not go forward beyond the housing (10). The grip (83) at the top of the swing arm (80) also does not go forward. The casing (10). As can be seen from the drawings and the above description, the length of the elliptical machine (i) in the front-rear axial direction of the present invention is generally "the length of the front and rear of the range of the crank arm (32) plus" The length of the front and rear of the range of the pedal (70). Therefore, compared with the conventional conventional elliptical machine, the elliptical machine (1) of the present invention can effectively reduce the footprint and space of the equipment while maintaining sufficient pedal release and good ergonomics (especially Reflected in the length of the front and rear). In this way, for household users whose indoor space is more limited, 13 1288008 can easily place equipment in the indoor corners, or relatively free space for activities, and is relatively unobstructed when carrying and moving. . Similarly, for the retailers or fitness center operators who are looking for empty materials, they can also display more sports equipment in the opposite area. For the manufacture of gas. In addition to reducing the storage density, it is more important to save material, packaging costs, and price to the product. Next, please refer to the elliptical machine (2) according to another preferred embodiment of the present invention from the seventh to the ninth embodiments. This embodiment can also achieve the above advantages of saving the space and the like, and the component composition, space, and dimensional relationship are also the same. The embodiments are substantially the same, and only the specific differences will be described below. (Note: In the embodiment, the components or parts corresponding to the previous embodiment, the representative symbols are all added with the corresponding number (')". () As shown in the figure, the rewinding mechanism in this embodiment (3) 〇,) has two left and right opposing skeletons (35), each of which has a cross shape, and an outer end of one of the branches (shaped as a crank arm) serves as a wraparound joint (34,). The front end of the frame body (2〇,) also has a casing (i〇,) covering the rewinding mechanism (3〇'), but the left and right sides of the casing (1〇,) each have a corresponding cross-shaped skeleton. a circular opening (12) of (35), and a disc (13) fixed to the skeleton (35) is sealed at the opening (12). The front end of each support rod (6 (Τ) is located outside the disc (13), and is pivoted to the rewinding contact (34,) by a pivot that traverses the disc (13), and the skeleton (35) can be pulled. And the disk (13) - the same rotation. Compared with the previous example, the housing (10') of the present embodiment has a narrow left and right width. The rear end of the base of the frame body (20,) is also provided with left and right extensions extending forward and backward. The guide rails (25,) are located on opposite sides of a 1288008 of a box-shaped cover (28), and the upper side of the guide rails (25,) are shielded by the cover (28) (Note: Figure 8 The middle cover is partially removed. The rear end of each support rod (60,) is located outside the cover (28), and the axle (64) is reinforced by the long slot (29) on the side of the cover (28). It is pivoted with the roller (6Γ) so that the roller (61,) rolling on the guide rail (25,) can be protected by the cover (28), which is safer than 4: Compared with the previous example, the flywheel in the embodiment (40) , ) is relatively small, and the position is lower than the rewind, the structure (30,) (in this case is set at a height close to the ground), so that the height of the casing (10,) can be lowered to be close to the rewinding machine In addition, the housing (1〇,) is internally provided with an intermediate wheel set (45), and the intermediate wheel set (35) is composed of a large diameter wheel and a small diameter wheel coaxially, and the winding mechanism The large pulley (33,) of (30,) is first connected to the small diameter wheel of the intermediate wheel set (45) by a belt loop sleeve (not shown), and the large diameter wheel of the intermediate wheel set (45) is again The small pulley (41,) of the flywheel (40,) is not shown in the other belt loop, thereby achieving a predetermined speed ratio transmission in a limited space. ^ In the previous embodiment, the pedal (70) is directly pivotally connected to the support rod (6〇), and the connecting rod (90) is not directly pivotally connected to the support rod (60) (but also indirectly through the pedal ( 7〇) forms a relative pivotal relationship). In this embodiment, the pedal is also pivotally connected to the support portion (62,) of the support rod (60,), except that the corresponding portion of the connecting rod (10)') is also the same as the shaft pivot. Connected to the branch (62'), and the back end of the flail (90') is bent inward to the bottom of the pedal (7〇,) (see Figure 7; the figure is taken in addition to the pedal (7〇,) The partial member) is pulled and fixed by the pedal (7〇,), so that the pedal (7〇,) is more balanced and stable with respect to the pivot structure of the support rod (60'). Other parts of the present embodiment which are not described in detail, in particular, the relative positions, distances, and dimensional ratios of the moving trajectories of the components and the components are all the same, and will not be described herein. The elliptical machine (2) of the present embodiment can also effectively reduce the footprint and space of the equipment while maintaining sufficient pedal travel and good ergonomics. In contrast to the previous example, the casing (10,) of this embodiment has a lower height and a narrower left and right width.
