DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a machine that can be effectively used for body forging. In addition, the present invention can be used as a fitness machine mainly for muscle development, and can also be used as a machine suitable for racing training, and thus its main purpose is to develop long-term operation. In particular, the exercise machine of the present invention has at least an instrument that can be used for repetitive alternating motion along an open track.
【先前技術】 在健身機領域，已知的機器有以下幾種：用於進行包括/ 開發肌肉部位之鍛鍊的機器；用於進行同時或連續開發多 處肌肉部位之鍛鍊，且為此目的而進行”功能性”分配之機 器；以及可進行重複性有氧/心血管鍛鍊，從而開發肌肉之 長時間耐力的機器。一般而言，第一種機器配備帶有配重 之負荷部，其中，鍛鍊過程可產生連續之偏心及同心效果， 而第二種機器所配備之負荷部可在使用者進行赛車運動 時’不中斷地與使用者連續交換能量。對於後者，最常見 的是固定式自行車’即用於行走或跑步之人力踏車、用於 模擬帶有階梯之路徑的所謂”階梯機”以及用於在移動式腳 踏板上沿者封閉之擴圓軌跡行走及/或跑動的擴圓執跡機。 固定式自行車、階梯機及橢圓執跡機均具有負荷部，其 藉由吸收由使用者發揮出之能量來工作，其中，人力踏車 既可由使用者來啟動，亦可由啟動器來驅動，啟動器確定 由使用者發揮出之能量。階梯機亦是一種，’浮動”型，在驅 動腳踏板期間傳送給負荷部之能量可確定使用者之重心相 101715-940818.doc 1275409 對機益底部的平均高度，從而影響運動幅度。賽車訓練機 中之滑冰模擬機亦廣為人知。 /其中，美國專利5,718,658所揭示之模擬機尤其廣為流 打。根據該專利之說明書，滑冰模擬機可並排配有一對大 致相同且沿縱軸轉動之支臂；每一支臂帶動一以其為樞軸 且在一相對自由之端點附近轉動的腳踏板；每一腳踏板有 一橫向條帶，用於防止自腳踏板上橫向滑出，從而抑制腳 之移動。每一桿件在一飛輪上借助機械傳動裝置來動作， 該機械傳動裝置配有一皮帶，皮帶沿其路徑繞在一活輪 上，從而與飛輪聯動，且在其相應的端點與一桿件及機架 連接’藉由接入一彈簧在該端點進行該連接。如此，每一 桿件在轉動中由皮帶來制動，而且桿件由相應的彈簧而返 回至中心止動位置。 此類機器概念有若干種不足：首先，使用者有不適感， 使用者在由很長的動作桿支撐之二個腳踏板上被抬離地 面；第二，在支臂自大致處於中心之止動位置移向遠端位 置期間，使用者之雙腳處於向前方向。因此，使用者之裸 關節便發生不自然的運動，雙腳會產生有異於實際滑冰運 動之感覺。在大運動量之場合下，此將造成使用者在桿件 上失衡，從而發生難以預見的後果。 為彌補上述的部分不足，可參照美國專利申請 2002/0042329之說明書，其中，各腳踏板在雙側由一内曲 棱形導桿來支撐。該導桿-腳踏板對之形狀可確定上述腳踏 板之執跡形狀’同時其形狀亦可改變其使用者腳踏面之傾 101715-940818.doc 1275409 斜狀態。因此’該導桿，踏板對可在推料動巾增加腳面 與腳踏板之間的夾持力，從而在各腳向外運動時，為使用 f提：更大的安全性。作為該申請說明書之實施方式的機 器負荷亦具有一飛輪，其可由與其同轴之一個飛輪來啟 - 動。此外，亦具有_彈性返回裝置，用於使腳踏板返回至 相對中〜位置。具體而言，該返回機構亦具有用於每一腳 踏板之可撓性部件，其包括互相串聯之一皮帶及一彈菁以 φ 及圓周運動皮帶輪。 然而，此發明概念有若干需要改進之處，即，若導桿/滑 桿、寸配備叙轉&，便會提局生產成本，因為導桿/滑桿對之 生產精度較局，且亦具有顯著磨損問題，其對操作成本產 生負面衫響，因為需要經常調節該導桿/滑桿對。此外，若 其尺寸與使用者之四肢長度直接有關，則該結構之絕對剛 性亦:降低腳踏板在運動中之幅度及角度調節之靈活性。 應注意的是，由於上述原因，因而在兩種發明概念中，各 鲁腳踏板均可自由動作，從而可使各負荷部一次由一腳踏板 $操作，或由二個腳踏板同時操作。此尤其適用於更精於 Θ水運動或肌肉發達且具有良好的平衡控制力之使用者。 出於上述原因，體現美國專利5718658及專利申請 0^2 = 9之呪明書的機器概念具有若干可改進之處，因為二 σ只知之運動類型並非滑冰運動之模擬形式，且亦因為 ^ X等°兒明書之機器無法良好適應各種身高使用者之人 體尺寸，且亦因為該等機器很笨重，效率低且成本很高， 而使用者部而要成本合理之小型健身機，且該機器應能用 101715-940818.doc 1275409 來在滑冰運動中增強肌肉力量。 【發明内容】 總之，本發明係關於一種能有效用於鍛鍊培訓之機器。 詳言之，本發明既可用於主要用來鍛鍊肌肉之健身機，亦 可用於用來進行賽車類訓練，從而主要開發長時間耐力之 機器。詳言之，本發明之健身機至少具有一可用來沿開放 執跡進行重複性交替運動之器具。 • 本發明之目的在於，建造一種能有效地進行模擬滑冰運 動之訓練的健身機。 本發明之另一目的在於，使使用者在腳踏板向外運動時 能獲得中心支撐，從而使機器可無差別地用於曾經滑過冰 及未滑過冰之使用者。 本發明之另一目的在於，建造一種外形尺寸小於其運動 幅度’且購買價袼及操作成本較低之模擬滑冰機器。 根據本發明來建造一種健身機，其特徵藉由參照請求項丄 ^ 及下文來說明。 【實施方式】 圖1中，整體1表示一種健身機，其具有框架10，其支撐 並排設置之負荷部2〇及鍛鍊站30。 、 該站30可與負荷部20交換機械能量，且至少具有一相鉸 接之機械部件對件31，其中的支臂35由框架1〇帶動，且圍 繞軸36旋轉，從而相對縱向傾斜，亦具有一器具4〇，其形 狀可與使用者四肢之特定部位相吻合，且在其端點與上述 支臂35可自由轉動地耦合。比如自圖2可看出，為安全起 101715-940818.doc -10- 1275409 見’腳踏板在相對之中心部位具有一立桿42，其可用作另 腳踏板40之緩衝器，亦可用來防止使用者雙腳處平衡棒 之間的直接衝擊，或防止涉及機器1使用過程中的干擾之類 似問題。因此，器具4〇可圍繞自己之轴線來旋轉，且可沿 者一彎曲開放之執跡P來運動，參見圖2，圖中以虛線及點 線來表不。如下文詳述，該執跡P圍繞著軸線36，且向下彎 曲’從而各器具40可自對應於機器1中心線上之縱向平面l 的較高位及處於侧面之較低位來開始運動。 以下為方便起見，利用一種較佳實施方式說明可用來模 擬滑冰運動之機器丨的情況，但是該選擇並非限定本發明概 念僅能應用於可用來進行除滑冰之外的其它形式訓練之健 身機。如上所述，機器丨具有二個並排設置且處於平面L之 對側的對件31，完全類似於已知的模擬滑冰運動之機器。 如此，在較佳實施方式中，將器具40設為腳踏板40。有關 平面L請參見圖2。 同樣為方便起見，為簡化附圖及對本發明之說明，一種 用於控制機器1之裝置並未示出，其係一種被稱為，，控制臺，， 之裝置，具體情況請參見有關說明。事實上，儘管該控制 臺一般具有用於調節有關使用者生理參數之機器特定功能 的指令，但本發明之概念中未涉及該裝置之說明。 鍛鍊站30之各對件31至少包括一受球形耦合件52縱向限 制之延展部件51，其將部件51連接至框架10及上述腳踏板 40上。具體而言，將部件51連接至框架上之球形耦合部處 於支臂35之旋轉軸線36—側，因而該部件51可限制各腳踏 101715-940818.doc 11 1275409 板40相對各支臂35之轉動，從而控制上述腳踏板4〇之表面 41上的腳相對對應支臂35之轉動。若有必要使腳踏板4〇之 動作適於使用者之需要，亦可使部件5丨之長度可隨意調 節。其效果是，使用者之每隻腳在腳踏板4〇沿平面L之推進 動程及返回至止動位置尺之動程中，由相應腳踏板4〇以匹配 /雙邊形式且沿著一開放圓形執跡p來支撐。基於上述原 因，即使該軌跡P之相應外部向下傾斜，亦會發生上述情 鲁况’其目的在於提高機器1之安全性，從而保護不當心的使 用者或訓練不足/不熟練的使用者。 基於上述說明，各腳踏板40將相關部件51與相關支臂35 相連接，二者可旋轉地連接至框架1〇上。因此，可旋轉地 連接支臂35與各部件51之腳踏板4〇可作為一桿件來起作 用而各對件3 1、框架1 〇與各部件5 1之組合以及鉸接方形 件43之形成，可產生一種限制裝置5〇，其可控制器具如相 對各支臂35之旋轉。該方形件43限制腳踏板4〇之表面4ι， •攸而在與表面41接觸且相對靜止的條件下，藉由圍繞軸線 %之旋轉運動組合，將置於腳踏板/桿件4〇項部之腳引導至 襲曰成執跡之空間。基於上述原因，各部件$ 1可產生各 腳踏板40之合成運動，尤其包括各腳踏板40在相關支臂35 之向外推進動程中的向内運動，以及腳踏板4〇之向前旋 轉：從而降低其前部44並抬高其後部45。腳踏板4〇之向内 侦斜可減緩膝蓋之向内彎曲，有助於踝關節在侧向推進時 之穩疋性，而腳踏板之向前傾斜則有助於使用者處於中心 位置之腳的重心穩定性。若腳踏板40保持平行，則使用者 1〇17l5.94〇8l8.d〇c -12- 1275409 在向後推進動程中，必須轉移他/她的重心，從而減弱處於 向前位置之腿部提供支撐的能力。此亦可使各使用者之腳 掌大致保持垂直，且相對腳踏板4〇之上表面41靜止，從而 不斷地與該表面41相配合。如此，便可基於生物力學，充 分利用使用者傳遞至支臂35的運動，其結果是，可實現使 ' 用者在完全動態平衡狀態下可產生之最大推進。此外，如 此便可自選能至少包容腳之一橫向部分的保持部件，從而 0 可簡化各腳踏板之結構，且可降低成本。在運動過程中， 腳踏板40之合成運動可由術語”外翻運動”來表示，因為當 腿部保持靜止時，該運動類似於腳掌可實施之彎曲及下翻 運動。意即，在各種使用情況下，當腳踏板4〇相對於相關 支臂35之軸線36旋轉時，二耦合器52隨時起到聯軸節之作 用，瞬間互相歪扭。 自機器1之體積及功能性的觀點出發，若站30之結構尺寸 較小’則一支臂3 5在縱向中間平面l上之布局便具有顯著優 _ 勢。此外，對於一定長度之支臂35而言，與腳踏板及其軸 線36處於平面L之同一側相比，各執跡p對於使用者之下 肢’特別是踝關節及腳部之生物力學更具有重要的意義。 ^ 另外，如此便會在腿部及腳部之向外運動期間，使使用者 發揮更持續的力量，尤其在對應於腳之"外翻運動”的上述 執跡P區内。然而應認識到，在特定運動條件下，支臂3 5 之特定結構可使使用者將各腳踏板4〇作為包容各軸線之一 整體帶動至平面L之同一側，以適應各使用者之滑冰姿態。 取後，如圖2所示，各支臂35之形狀互相各異，以防止在機 101715-940818.doc 1275409 益1之運動期間，在各支臂35之間或各腳踏板4〇之間發生碰 撞。對各支臂35帶有止動器37之各支臂亦如此。 應認識到，儘管腳踏板所追隨之執跡p有必要相對平面L 對稱，但若機器1用於訓練通常為對稱狀態之下肢，則各支 臂35之形狀必須互相各異，以防止相互之間可能產生之干 擾。因此，對件31係不對稱的，且各支臂35藉由其自身之 自己軸36,在對側且相對平面L自各腳踏板4〇來支撐，且可 Φ 在自止動處R之各位置開始的該區域空間内運動。亦應注意 到，腳踏板40之軌跡P除了為圓周狀且以軸％為中心之外， 亦可在平面L上具有至少一段最小共用長度。對於機器i， 支臂35之特定幾何配置及其各軸線36之定向決定了腳踏板 40之執跡P將在相對平面l幾何定位之一個點上相交。 參見圖1及圖3，部件20包括一其形狀適於儲存旋轉能量 之旋轉部件25，典型的是一飛輪25，其由框架1〇藉由一軸 來支撐，該轴為眾所周知的，因而未圖示，其藉由鍵而連 _ 接電磁制動器24之圓盤23，其可連續消耗可調整之能量。 此外，機器1在負荷部20與鍛鍊站30之間，配有一機械傳動 器21，其可將各支臂35之交變旋轉運動轉換成飛輪乃之旋 轉運動。該傳動器21包括一惰輪27，其在懸臂桿内藉由鍵 而連接至水平轴38上，水平軸處於框架1〇内圖2所示之二支 撐之間。該惰輪27可藉由與上述飛輪25同軸之皮帶29及小 軸32，與飛輪25同步旋轉。此外，傳動器21包括至少一用 於各支臂35之皮帶33，各皮帶33繞在多個皮帶輪22上，皮 帶輪由框架10可自由旋轉地支撐，皮帶在負荷部2〇内連接 101715-940818.doc -14- 1275409 對應之支臂35及自由輪34。各輪34僅能在一方向傳輸扭 矩，若在相反方向啟動，則僅能空轉，其鍵合至軸38上， 從而藉由傳動器21之皮帶29將動能傳遞至飛輪25。因此， 各腳踏板4 0以及相應的支臂3 5可分別啟動，而與運動條件 或其匕腳踏板4 0之止動狀悲無關’儘管如此，如下所述， 亦可利用相關支臂35限制腳踏板40之旋轉。 應指出的是，負荷部20之種類可隨在上述機器1上進行之 $ 訓練類型而異，尤其是有氧/心血管或肌肉/無氧訓練。因 此’部件20可為電磁類型，且可配備制動器24，如圖1及圖 3所示，若欲進行有氧型訓練，則部件20亦可為一種機械類 型’且至少配備帶有配重之裝置70，以用於肌肉/有氧訓 練，如圖4所示。在任何一場合下，裝置23及裝置7〇均可被 看作用於控制由使用者傳送至各腳踏板4〇的能量之裝置 60 〇 為了簡化，省略了制動器24及裝置70之詳細描述，其原 ^ 因在於，第一’兩種裝置之結構均係已知；第二，本發明 之實施方式不取決於負荷部之類型選擇。在任何情況下， 如圖4所示，對各部件20均適用於門，架結構71，該結構對各 支臂35支撐配重73之組件72,各組件72可藉由纜索74，在 腳踏板40之作用下垂直啟動。 返回至滑冰運動’應注意的是’滑冰者一般在交換各腳 時向前推進，因而各腳將產生相同時間之暫停。因此，為 有效地產生該運動，可向未啟動的腳踏板41之中心施加一 返回力；因此機括一圖3及圖5所示之反作用裝置8〇, 101715-940818.doc -15- 1275409 其可對各支臂35施加一向内之返回作用，並使各支臂^返 回中心位置，從而起到安全裝置的作用。該運動之強度必 須選擇為與朝向各上述支臂35之外轉動之角度大小成比 例，出於此原因，裝置80必須具有一種彈性機械特性。出 於此種考慮，裝置80可具有不同的實施方式，其一般至少 具有-藉由傳送機械21作用於丨臂35上之彈性返回部件。 根據圖3,反作用裝置80至少包括皮帶82，其在各支臂35 •之間設置成一種倒”U”字形，從而將其大致剛性地相連接， 且其末端繞在軸38上，纏繞方向與各皮帶33在各皮 上之纏繞方向相反。如此，在腳踏板4〇之動作動程期間， 在皮帶33藉由皮帶29之張緊而脫離纏繞時，皮帶^便可缠 繞至軸38上。皮帶82藉由皮帶輪83而持續受牽引作用，該 皮帶輪藉由托架84，由框架10彈性地支撐，托架84由支臂 85支樓’支臂85在皮帶輪83之相反端由鉸鏈連接至框㈣ 上，從而由彈性返回部81彈性制約，彈性返回部81至少包 _括一藉由相應的端部與框架1〇連接之彈簧％。如此，藉由 ^作用裝置80且利用各彈簧86，冑性返回力便作用至各支 ^ 35上。因而，在各腳踏板40每次向外運動後，彈簧86便 藉由支臂85，將彈性力施加至其它腳踏板牝上，該力係支 臂85之長度與彈性返回部81之彈性常數的函數。 ’、 —根據上述說明，冑置8〇基於其各種類$，即使使用者未 文過滑冰運動訓練，或使用者未從事過此類運動，亦可無 風險地應用機器丨。 … 此外’自上述說明可看出，與某些進行攀登樓梯運動之 101715-940818.doc -16- 1275409 機器或階梯機相類似，在機器丨中，無需使用者之活動便可 降低重力高度。基於該原因，框架10配有一前部u，其形 狀可使使用者在登上或走下上述機器丨時傾身，或在訓練過 程中對腿部之推進施加雙侧反作用力。 若彈簧86配用縱向延伸且與未變形彈簧86大致相同且與 圖3之彈簧86—同表示的剛性體86b，則可防止支臂以相對 框架10轉動，從而可限制各支臂35相互轉動，即使使用者 不熟悉機器1亦可。 最後，在不脫離本發明範圍之前提下，可對此處所述及 圖示之機器1進行修改及變動係顯而易見。 為清晰起見，在上述機器}之說明中，僅在各腳踏板40 向外推進之偏心推進動程中動作，從而傳遞能量，而在使 腳踏板40返回至中心的過程中則不動作，比如，滑冰運動 中之發生過程。然而，本發明亦可藉由下述機器來實施， 該機器在使腳踏板40返回至中心的動程中亦提供用於吸收 之能量，比如，增設與上述安裝之負荷部大致相同但動作 相反之負荷部20。 比如，若濕為有必要使由上述部件施加之裝置8〇的彈性 作用與使用者特徵相匹配，則可根據圖5a改進裝置8〇，使 彈性返回部81配備用於各支臂35之彈簧87，或根據圖兄所 不，使裝置80配備用於各支臂35之彈簧87及處於支臂35之 間從而將其彈性地相連接之彈簧88。纟圖讣中，為簡化起 見，彈簧88分為兩個彈性部9〇，其處於由框架切支撐之皮 帶輪89的對面，但是可分別實施動作，而無需改變其操作。 由此易於了解··圖5b中的彈簧88實等同於圖3中的皮帶以。 101715-940818.doc -17- 1275409 根據圖3或根據圖5a或5b來選擇反作用力之類型時，應取 決於使用者最相信能滿足他/她之訓練類型的效果種類，上 述三種不同方式不應理解為限定反作用裝置8〇之可能實施 方式，其係僅用於例示上述裝置8〇之可能實施方式。 根據上述說明，必須注意到，在機器1中，無法排除下述 可能性，即：各支臂35之延長部件5 1亦會受到彎曲應力而 非僅又到正常應力。眾所周知，當较接方形件之軸處於運 φ 動狀悲且僅受正常應力作用時，鉸接方形件可穩定地保持 其頂點軌跡之穩定性，僅在機器丨之此狀態下，訓練量或使 用量較少之使用者才會發現該機器係令人舒適且安全的。 為防止腳踏板40之執跡發生不可預見之變動，從而對使用 者造成潛在危害，可將機器丨替換為圖7及圖8所示之機器 101，其中，為了與機器1中已說明過之類似部件相區分， 所採用之參照號與已使用之參照號相差1〇〇，除非另有指 定。具體而言，機器1〇1配備一對帶有彎頭之支臂135，其 •各自圍繞軸136旋轉，且對各直線行程配有一限制裝置50， 該裝置具有一種類似於鉸接方形件43之鉸接機構。 參見圖8,各支臂135具有彎頭137及二方形件153及154， 其可互相聯動，從而利用通用桿件157,控制各腳踏板14〇 相董子支臂135之角度位置。該桿件157為方形件154之連接 桿’同時亦為方形件153之曲柄，該桿件在相應彎頭⑺之 附近由支臂135可自由旋轉地帶動。 在本文巾，自圖8可看ώ，方形件153與機器i共用各框架 U〇 ’而第二方形件154之框架則配有各支臂135。此外，仍 101715-940818.doc -18- 1275409 參見該等圖，方形件153配有延長部件155，其可用作連接 桿，而方形件154則配有一延長部件i 56，其用作一平衡件。 邛件155及156由各球形連接件152限定，且與部件51類似， 其長度可調節，從而調節各腳踏板140及各上表面141之運動。 同樣，各部件155/156可產生各腳踏板14〇之合成運動， 尤其在支臂135之向外推進及腳踏板4〇之向前旋轉動程 中，可使各腳踏板140向内傾斜，從而可降低其前部144， ^ 同時抬高其後部145。 機器ιοί亦包括一反作用裝置180，其作用於每一支臂35 上一内部回復作用，試圖將每一支臂35回復至中央位置， 因此，其亦起到一安全裝置作用。參照圖7,機器1〇1配有 一機械傳動裝置121，其處於負荷部12〇與站13〇之間，能夠 將各支臂135之交變旋轉運動轉換成飛輪125之旋轉。該傳 動裂置121與機器i類似，至少具有一用於各支臂135之皮帶 133,且各皮帶133纏繞在自由輪134上，該輪藉由接入一由 •軸138下之框架110支撐之皮帶輪122而由軸138帶動。各輪 134被鍵合至飛輪125旁邊之軸138上，從而將運動扭矩傳送 至上述飛輪125上，其藉由接入一具有平行軸線之聯軸節 139而與制動器124機械連接。可看出，機器丨與機器ι〇ι之 不同之處亦在於，傳動裝置21及傳動裝置121分別具有一級 及二級平行軸聯軸節。對於機器1〇1而言，可採用其轉速大 大超過制動器24之制動器124，因而可進行更為精確之控 制。 再次參照圖7,反作用裝置18〇配有用於各支臂135之彈性 101715-940818.doc -19- 1275409 返回部件186，其用於使相關支臂135返回至各自之止動位 置R。最妤使用一大直徑扭轉彈簧啟動各部件1 86，但並非 限定於此，且二彈簧186由皮帶輪122下方且處於軸138與制 動器124之間的框架110而互相同軸。根據圖7，採用大直徑 扭轉彈簧186，可有助於大大減小機器101之縱向尺寸，具 有可增強上述機器之剛性且減小體積之優勢。因此作為其 結果，裝置180與機器1之裝置80相比，體積更小。 | 此外，裝置180亦配有延長部件195，如圖8所示，該部件 處於各支臂135之間，使其互相連接，如下文所示，其長度 係施加至腳踏板140上的力之函數，從而產生一與兩個支臂 13 5之間之角距成比例的約束作用。參見圖9，部件19 5大體 上係一緩衝器結構，根據圖8，其藉由鉸接端部152與各支 臂135而連接。具體而言，部件195配有殼體198，其同轴且 自由地覆蓋桿件199’殼體198及桿件199由一對彈性常數各 異且固定之第一彈簧196及197互相連接。彈簧196具有較低 • 彈性常數，且彈簧196及197互相串聯設置，且可作為一具 有固定值之彈性體起作用，從而在桿件199處於殼體198内 之動程末端位置時，縮減該點之阻尼作用，彈簧及196 為線圈纏繞式。基於上述說明，部卡 ’部件195主要藉由具有較低[Prior Art] In the field of fitness machines, there are known machines: machines for performing exercise including/developing muscle parts; exercises for simultaneously or continuously developing multiple muscle parts, and for this purpose A machine that performs "functional" dispensing; and a machine that can perform repetitive aerobic/cardiovascular exercise to develop long-term endurance of muscles. In general, the first machine is equipped with a load section with counterweights, in which the exercise process produces continuous eccentricity and concentricity, while the second machine is equipped with a load section that can be used when the user is racing. The energy is continuously exchanged with the user without interruption. For the latter, the most common ones are stationary bicycles, ie man-made treadmills for walking or running, so-called "stepping machines" for simulating paths with steps, and for closing on mobile pedals. Expanding the track and/or running the rounding and retracting machine. The fixed bicycle, the step machine and the elliptical tracker each have a load portion, which works by absorbing the energy exerted by the user, wherein the human treadmill can be started by the user or driven by the starter. The device determines the energy played by the user. The step machine is also a type of 'floating type'. The energy transmitted to the load during the driving of the pedal can determine the average height of the user's center of gravity 101715-940818.doc 1275409 on the bottom of the machine, thus affecting the range of motion. The skating simulator in the training machine is also widely known. / The simulator disclosed in U.S. Patent No. 5,718,658 is particularly widely used. According to the specification of the patent, the skating simulator can be arranged side by side with a pair of substantially identical and rotating branches along the longitudinal axis. An arm; each arm carries a foot pedal pivoted about it and adjacent to an end of the relatively free end; each foot pedal has a transverse strip for preventing lateral sliding out of the foot pedal, Thereby the movement of the foot is inhibited. Each of the rods acts on a flywheel by means of a mechanical transmission which is provided with a belt which is wound along a path on a flywheel for linkage with the flywheel and in its corresponding The end point is connected to a rod and a frame. The connection is made at the end by accessing a spring. Thus, each rod is braked by the skin during rotation, and the rod is correspondingly The spring returns to the central stop position. There are several deficiencies in this type of machine concept: first, the user feels uncomfortable and the user is lifted off the ground on two pedals supported by a long action bar; Second, during the movement of the arm from the substantially central stop position to the distal position, the user's feet are in the forward direction. Therefore, the user's bare joints are unnaturally moving, and the feet may be different. The feeling of the actual skating movement. In the case of a large amount of movement, this will cause the user to be unbalanced on the rod, and unpredictable consequences occur. To compensate for the above-mentioned deficiencies, reference can be made to the specification of the US Patent Application 2002/0042329. Wherein, each foot pedal is supported on both sides by an inner curved guide rod. The shape of the guide rod-foot pedal pair can determine the shape of the foot pedal, and its shape can also change its user. The tread surface tilts 101715-940818.doc 1275409. The guide bar, the pair of pedals can increase the clamping force between the foot surface and the foot pedal in the pusher movement, so that when the feet move outward, To make f: greater safety. The machine load as an embodiment of the specification of the application also has a flywheel which can be activated by a flywheel coaxial therewith. In addition, there is also an elastic return device for the foot The pedal returns to the relative center-to-position. Specifically, the return mechanism also has a flexible member for each of the foot pedals, including one belt and one belt in series with each other and a circular motion pulley. There are several improvements in the concept of the invention, that is, if the guide/slider and the inch are equipped with the revolving &, the production cost will be raised because the production precision of the guide/slider pair is relatively small, and also has Significant wear problems, which have a negative impact on the operating cost, because the guide/slider pair needs to be adjusted frequently. Moreover, if the size is directly related to the length of the user's limbs, the absolute rigidity of the structure is also: lowering the pedal The flexibility of the plate in motion and the flexibility of angle adjustment. It should be noted that, for the above reasons, in the two inventive concepts, each of the foot pedals can be freely operated, so that each load portion can be operated by one foot pedal $ at a time, or by two foot pedals simultaneously. operating. This is especially true for users who are more proficient in drowning or muscular and have good balance control. For the above reasons, the machine concept embodying the patents of US Pat. No. 5,718,658 and the patent application 0^2 = 9 has several improvements, since the type of motion known by the two sigma is not a simulated form of skating, and also because of ^ X The machine of the book can not be well adapted to the body size of users of various heights, and because the machines are cumbersome, inefficient and costly, and the user department has a reasonable cost of the small exercise machine, and the machine It should be able to use 101715-940818.doc 1275409 to increase muscle strength during skating. SUMMARY OF THE INVENTION In summary, the present invention is directed to a machine that can be effectively used in exercise training. In particular, the present invention can be applied to both a fitness machine mainly used for exercising muscles, and a machine for training in a race, thereby mainly developing a long-term endurance machine. In particular, the exercise machine of the present invention has at least one implement that can be used for repetitive alternating motion along an open track. • The object of the present invention is to construct a fitness machine that can effectively perform training for simulating skating movements. Another object of the present invention is to provide a central support for the user to move the foot pedal outwardly so that the machine can be used indiscriminately for users who have ever slid over ice and have not slid over ice. Another object of the present invention is to construct a simulated skating machine having an outer dimension smaller than its range of motion and having a lower purchase price and lower operating cost. In accordance with the present invention, a fitness machine is constructed, the features of which are illustrated by reference to the request item and the following. [Embodiment] In Fig. 1, the whole 1 indicates a fitness machine having a frame 10 that supports a load portion 2 and a training station 30 arranged side by side. The station 30 can exchange mechanical energy with the load portion 20 and has at least one mechanical component pair 31 hinged thereto, wherein the arm 35 is driven by the frame 1 , and rotates about the shaft 36 so as to be inclined relative to the longitudinal direction, and has An instrument 4 is shaped to conform to a particular portion of the user's extremities and is rotatably coupled to the arm 35 at its end. For example, as can be seen from Figure 2, for safety 101715-940818.doc -10- 1275409 See 'The pedal has a pole 42 at the opposite center, which can be used as a buffer for the other foot 40, also It can be used to prevent direct impact between the balance bars at the user's feet, or to prevent similar problems involving interference during use of the machine 1. Therefore, the appliance 4 can be rotated about its own axis and can be moved along a curved open trace P, see Fig. 2, which is indicated by dashed lines and dotted lines. As detailed below, the track P is about the axis 36 and is bent downward so that each of the implements 40 can begin to move from a higher position corresponding to the longitudinal plane l on the centerline of the machine 1 and a lower position on the side. In the following, for convenience, a preferred embodiment is used to illustrate the case of a machine that can be used to simulate the skating motion, but the choice is not limited to the concept of the present invention, which can only be applied to fitness machines that can be used for other forms of training other than skating. . As mentioned above, the machine has two opposing members 31 arranged side by side and on the opposite side of the plane L, exactly like the known machine for simulating skating movement. As such, in the preferred embodiment, the appliance 40 is configured as a foot pedal 40. See Figure 2 for the plane L. Also for convenience, to simplify the drawing and the description of the present invention, a device for controlling the machine 1 is not shown, which is a device called a console, and the details are as described. . In fact, although the console typically has instructions for adjusting machine specific functions relating to physiological parameters of the user, the description of the device is not addressed in the concept of the present invention. Each pair 31 of exercise stations 30 includes at least one extension member 51 that is longitudinally constrained by a spherical coupling member 52 that connects the member 51 to the frame 10 and the foot pedal 40 described above. Specifically, the spherical coupling portion connecting the member 51 to the frame is on the side of the rotation axis 36 of the arm 35, so that the member 51 can limit the pedals 101715-940818.doc 11 1275409. Rotating to control the rotation of the foot on the surface 41 of the foot pedal 4 to the corresponding arm 35. If it is necessary to adapt the action of the footrest 4 to the needs of the user, the length of the member 5 can be adjusted at will. The effect is that each foot of the user is in the matching/bilateral form and along the corresponding foot pedal 4〇 in the movement of the foot pedal 4〇 along the plane L and the return to the stop position. An open circular obstruction p is used to support. For the above reasons, even if the corresponding outer portion of the trajectory P is tilted downward, the above situation occurs. The purpose is to improve the safety of the machine 1, thereby protecting an insatiable user or a poorly trained/unskilled user. Based on the above description, each footrest 40 connects the associated component 51 with the associated arm 35, which are rotatably coupled to the frame 1A. Therefore, the rotatably connected arm 35 and the foot pedal 4 of each member 51 can function as a rod and the pair of members 31, the combination of the frame 1 and the members 5 1 and the hinged square member 43 Formed, a restriction device 5 can be created which can be rotated relative to each of the arms 35. The square member 43 limits the surface 4 of the footrest 4〇, and is placed on the pedal/bar member 4 by a combination of rotational movement about the axis % under the condition of being in contact with the surface 41 and relatively stationary. The foot of the item leads to the space where the attack is made. For the above reasons, each component $1 can produce a combined motion of each of the footrests 40, including, inter alia, an inward motion of each of the footrests 40 in the outward propulsion of the associated arms 35, and a foot pedal 4 Rotating forward: thereby lowering its front portion 44 and raising its rear portion 45. The inward tilting of the foot pedal 4〇 can slow the inward bending of the knee, helping the ankle joint to be stable when pushed laterally, while the forward tilting of the pedal helps the user to be in the center position. The center of gravity of the foot is stable. If the foot pedal 40 is kept parallel, the user 1〇17l5.94〇8l8.d〇c -12- 1275409 must shift his/her center of gravity during the backward propulsion process, thereby weakening the leg in the forward position. Provide the ability to support. This also allows the feet of each user to remain substantially vertical and to rest relative to the upper surface 41 of the footrest 4 , so as to constantly engage the surface 41. In this way, the movement of the user to the arm 35 can be fully utilized based on biomechanics, with the result that the maximum advancement that can be produced by the user in a fully dynamic equilibrium state can be achieved. In addition, it is possible to select a holding member that can accommodate at least one of the lateral portions of the foot, so that the structure of each foot pedal can be simplified and the cost can be reduced. During exercise, the resultant motion of the foot pedal 40 can be represented by the term "overturn motion" because when the leg remains stationary, the motion is similar to the bending and flipping motions that the foot can perform. That is, in various use cases, when the foot pedal 4 turns relative to the axis 36 of the associated arm 35, the two couplers 52 act as couplings at any time, momentarily twisting each other. From the viewpoint of the volume and functionality of the machine 1, if the structure of the station 30 is small, the layout of the arm 35 on the longitudinal intermediate plane l has a significant advantage. In addition, for a length of arm 35, each of the tracks p is more biomechanical to the user's lower limbs, particularly the ankles and feet, than the foot pedal and its axis 36 are on the same side of the plane L. Has an important meaning. ^ In addition, this will allow the user to exert a more sustained power during the outward movement of the legs and feet, especially in the above-mentioned Existence P area corresponding to the foot's "overturning movement". However, it should be recognized By the way, under certain motion conditions, the specific structure of the arm 35 can allow the user to drive each of the footrests 4〇 as one of the contained axes to the same side of the plane L to suit the skating posture of each user. After taking it, as shown in FIG. 2, the shapes of the arms 35 are different from each other to prevent the movement between the arms 35 or the pedals during the movement of the machine 101715-940818.doc 1275409. Collisions occur. The same is true for the arms of each arm 35 with the stopper 37. It should be recognized that although the foot pedal is required to follow the path p, it is necessary to be symmetrical with respect to the plane L, but if the machine 1 is used for training Usually in the symmetrical lower limbs, the shapes of the arms 35 must be different from each other to prevent interference with each other. Therefore, the members 31 are asymmetrical and the arms 35 are themselves The shaft 36 is supported on the opposite side and opposite to the plane L from each foot pedal 4〇, and Φ moves in the space of the area starting from each position of the stop position R. It should also be noted that the track P of the footboard 40 has a circumferential shape and is centered on the axis %, and may also have a plane L At least a minimum common length. For machine i, the particular geometric configuration of the arms 35 and the orientation of each of the axes 36 determines that the track P of the footrest 40 will intersect at a point relative to the geometric positioning of the plane l. 3, member 20 includes a rotating member 25 shaped to store rotational energy, typically a flywheel 25 supported by a frame 1 by a shaft that is well known and thus not shown. The disk 23 of the electromagnetic brake 24 is connected by a key, which can continuously consume the adjustable energy. Further, the machine 1 is provided with a mechanical actuator 21 between the load portion 20 and the exercise station 30, which can The alternating rotational motion of the arm 35 translates into a rotational motion of the flywheel. The actuator 21 includes an idler 27 that is coupled to the horizontal shaft 38 by a key in the cantilevered rod, the horizontal axis being in the frame 1〇 Between the two supports shown in 2. The idler 27 can The belt 29 and the small shaft 32 coaxial with the flywheel 25 rotate in synchronization with the flywheel 25. Further, the actuator 21 includes at least one belt 33 for each arm 35, and each belt 33 is wound around a plurality of pulleys 22, pulleys The frame 10 is rotatably supported by the frame 10, and the belt connects 101715-940818.doc -14-1275409 corresponding arm 35 and free wheel 34 in the load portion 2〇. Each wheel 34 can only transmit torque in one direction, if on the contrary When the direction is activated, it can only be idling, and it is bonded to the shaft 38, so that the kinetic energy is transmitted to the flywheel 25 by the belt 29 of the actuator 21. Therefore, the pedals 40 and the corresponding arms 35 can be activated separately. However, it is irrelevant to the movement condition or the stop motion of the pedal foot 40. However, as described below, the rotation of the foot board 40 can also be restricted by the associated arm 35. It should be noted that the type of load portion 20 may vary depending on the type of training performed on the machine 1 described above, particularly aerobic/cardiovascular or muscle/anaerobic training. Thus, component 20 can be of the electromagnetic type and can be equipped with a brake 24, as shown in Figures 1 and 3, if aerobic training is desired, component 20 can also be a mechanical type 'and at least equipped with a counterweight. Device 70 is used for muscle/aerobic training as shown in FIG. In either case, the device 23 and the device 7 can be viewed as means 60 for controlling the energy delivered by the user to each of the footrests. For the sake of simplicity, a detailed description of the brakes 24 and 70 is omitted. The original reason is that the structure of the first 'two devices are known; secondly, the embodiment of the present invention does not depend on the type selection of the load portion. In any case, as shown in Figure 4, each component 20 is adapted to a door, frame structure 71 that supports the assembly 72 of the weight 73 for each arm 35, each of which can be supported by a cable 74 at the foot The pedal 40 is activated vertically. Returning to the skating sport 'It should be noted that the skater generally advances while exchanging the feet, so each foot will produce a pause for the same time. Therefore, in order to effectively generate the motion, a returning force can be applied to the center of the unactuated footrest 41; therefore, a reaction device 8A shown in Figs. 3 and 5 is included, 101715-940818.doc -15- 1275409 It can apply an inward returning action to each arm 35 and return each arm to a central position, thereby functioning as a safety device. The strength of the motion must be chosen to be proportional to the angle of rotation outside of each of the arms 35. For this reason, the device 80 must have an elastic mechanical property. In view of this consideration, the device 80 can have a different embodiment, generally having at least - an elastic return member that acts on the ankle arm 35 by the transfer mechanism 21. According to Fig. 3, the reaction device 80 comprises at least a belt 82 which is arranged in an inverted U-shape between the arms 35, so as to be substantially rigidly connected, and whose ends are wound around the shaft 38, in the winding direction. The winding direction of each belt 33 on each skin is opposite. Thus, during the movement of the footrest 4, the belt can be wound onto the shaft 38 when the belt 33 is unwound by the tension of the belt 29. The belt 82 is continuously pulled by the pulley 83, which is elastically supported by the frame 10 by the bracket 84, and the bracket 84 is hinged to the opposite end of the pulley 83 by the arm 85 of the arm 85. The frame (4) is elastically restrained by the elastic return portion 81, and the elastic return portion 81 includes at least a spring % connected to the frame 1〇 by the corresponding end portion. Thus, by the action device 80 and by the springs 86, the inertial return force acts on each of the legs 35. Therefore, after each pedal 40 is moved outward, the spring 86 applies an elastic force to the other pedal pedals by the arm 85, which is the length of the arm 85 and the elastic return portion 81. A function of the elastic constant. According to the above description, the device 8 is based on its various classes of $, and the machine can be applied without risk even if the user has not trained in skating exercise or the user has not engaged in such exercise. ... In addition, as can be seen from the above description, similar to some 101715-940818.doc -16-1275409 machines or ladders for climbing stairs, in the machine, the height of gravity can be reduced without the user's activities. For this reason, the frame 10 is provided with a front portion u which is shaped to allow the user to lean over when boarding or walking the machine, or to apply a double-sided reaction to the advancement of the leg during training. If the spring 86 is provided with a rigid body 86b extending longitudinally and substantially identical to the undeformed spring 86 and being represented by the spring 86 of FIG. 3, the arms can be prevented from rotating relative to the frame 10, thereby restricting the rotation of the arms 35 to each other. Even if the user is not familiar with the machine 1. Finally, modifications and variations of the machine 1 described and illustrated herein will be apparent, without departing from the scope of the invention. For the sake of clarity, in the description of the above-mentioned machine, only the eccentric propulsion stroke in which each of the footboards 40 is pushed forward is performed to transmit energy, and in the process of returning the footboard 40 to the center, Actions, such as the process of skating. However, the present invention can also be implemented by a machine that also provides energy for absorption in the process of returning the footrest 40 to the center, for example, adding an action similar to that of the above-described installed load portion. The load portion 20 is opposite. For example, if it is necessary to match the elastic action of the device 8〇 applied by the above-mentioned components to the user's characteristics, the device 8〇 can be modified according to Fig. 5a so that the elastic return portion 81 is provided with a spring for each arm 35. 87, or according to the figure, the device 80 is provided with a spring 87 for each arm 35 and a spring 88 between the arms 35 to elastically connect them. In the drawings, for the sake of simplicity, the spring 88 is divided into two elastic portions 9 对 which are opposite to the pulley 89 which is supported by the frame, but can be separately operated without changing its operation. It is thus easy to understand that the spring 88 in Fig. 5b is identical to the belt in Fig. 3. 101715-940818.doc -17- 1275409 When selecting the type of reaction force according to Figure 3 or according to Figure 5a or 5b, it should depend on the type of effect that the user most believes can satisfy his/her training type. The above three different ways are not It should be understood that a possible embodiment of the reaction device 8 is defined, which is only used to illustrate a possible implementation of the device 8 described above. In light of the above description, it must be noted that in the machine 1, it is not possible to exclude the fact that the extension member 51 of each arm 35 is also subjected to bending stress and not only to normal stress. It is well known that when the axis of the square piece is in motion and is only subjected to normal stress, the hinged square piece can stably maintain the stability of its apex trajectory, only in the state of the machine, the amount of training or use A small number of users will find the machine to be comfortable and safe. In order to prevent unforeseen changes in the execution of the footrest 40, thereby causing potential harm to the user, the machine 丨 can be replaced with the machine 101 shown in FIGS. 7 and 8, which has been described in connection with the machine 1. The similar components are distinguished, and the reference number used is different from the used reference number unless otherwise specified. In particular, the machine 1〇1 is provided with a pair of arms 135 with elbows, each of which rotates about a shaft 136, and is provided with a restriction device 50 for each linear stroke, the device having a similar shape to the hinged square member 43 Hinged mechanism. Referring to Fig. 8, each arm 135 has an elbow 137 and two square members 153 and 154 which are interlocked with each other to control the angular position of each of the footboards 14 by the universal lever member 157. The lever member 157 is a connecting rod of the square member 154 and is also a crank of the square member 153. The lever member is freely rotatable by the arm 135 in the vicinity of the corresponding elbow (7). In the present document, it can be seen from Fig. 8 that the square member 153 shares the frames U〇' with the machine i and the frame of the second square member 154 is provided with the arms 135. In addition, still 101715-940818.doc -18- 1275409 Referring to the figures, the square member 153 is provided with an extension member 155 which can be used as a connecting rod, and the square member 154 is provided with an extension member i 56 which serves as a balance Pieces. The jaws 155 and 156 are defined by respective ball joints 152 and, similar to the member 51, are adjustable in length to adjust the movement of each of the footrests 140 and the respective upper surfaces 141. Similarly, each component 155/156 can produce a combined motion of each of the foot pedals 14〇, particularly in the outward advancement of the arms 135 and the forward rotation of the footrests 4〇, which can cause the foot pedals 140 to The inner portion is inclined so that the front portion 144 thereof can be lowered, and the rear portion 145 is raised at the same time. The machine ιοί also includes a reaction device 180 that acts on an internal return of each arm 35 in an attempt to return each arm 35 to a central position and, therefore, also functions as a safety device. Referring to Fig. 7, the machine 1〇1 is provided with a mechanical transmission 121 which is between the load portion 12A and the station 13A, and is capable of converting the alternating rotational motion of each arm 135 into the rotation of the flywheel 125. The transmission split 121 is similar to the machine i, having at least one belt 133 for each arm 135, and each belt 133 is wound around a free wheel 134 that is supported by a frame 110 under the shaft 138. The pulley 122 is driven by the shaft 138. Each wheel 134 is keyed to a shaft 138 beside the flywheel 125 to transmit motion torque to the flywheel 125, which is mechanically coupled to the brake 124 by accessing a coupling 139 having parallel axes. It can be seen that the difference between the machine 丨 and the machine 在于 is that the transmission 21 and the transmission 121 have primary and secondary parallel shaft couplings, respectively. For the machine 1〇1, the brake 124 whose rotational speed is much larger than the brake 24 can be used, so that more precise control can be performed. Referring again to Figure 7, the reaction device 18A is provided with a resilient 101715-940818.doc -19-1275409 return member 186 for each arm 135 for returning the associated arms 135 to their respective stop positions R. Finally, the various members 186 are activated using a large diameter torsion spring, but are not limited thereto, and the two springs 186 are coaxial with each other by the frame 110 below the pulley 122 and between the shaft 138 and the brake 124. According to Figure 7, the use of a large diameter torsion spring 186 can help to greatly reduce the longitudinal dimension of the machine 101, with the advantage of enhancing the rigidity of the machine and reducing the volume. As a result, the device 180 is smaller in size than the device 80 of the machine 1. In addition, the device 180 is also provided with an extension member 195 which, as shown in Figure 8, is placed between the arms 135 to be interconnected, as shown below, the length of which is applied to the footrest 140. A function that produces a constraint proportional to the angular separation between the two arms 13 5 . Referring to Figure 9, component 19 5 is generally a bumper structure which, according to Figure 8, is coupled to each arm 135 by a hinged end 152. Specifically, the member 195 is provided with a housing 198 that coaxially and freely covers the rod member 199'. The housing 198 and the rod member 199 are interconnected by a pair of first springs 196 and 197 having different spring constants and being fixed. The spring 196 has a lower • spring constant, and the springs 196 and 197 are disposed in series with one another and can function as a resilient body having a fixed value to reduce the rod 199 when it is in the end position of the end of the housing 198. The damping of the point, the spring and 196 are coil wound. Based on the above description, the part card 'component 195 is mainly made lower by

In this way, the pedaling action of the pedals triggers the action of the other pedals in a coordinated manner. If such a situation is desired, it may be considered that the rigid member replacement component 195' may of course be brought in the initial transition phase. Operation problem 'Because the user must start the movement with each foot pedal at the minimum rotation, and therefore - the unsafe static balance condition. After: ~, under the minimum distance between each foot pedal And when the branches are in their respective stop positions, or in use in the vicinity of the plane L, the catch member 195 can be kept in line with the footrest 140, thereby preventing the angle between the arms 135 from exceeding a fixed value, which can be The device is used to calibrate the springs 196 and 197 and the minimum length specified for the component 195 is established to ensure that the user maintains an equilibrium state. In other words, the component 195 b is sufficient to limit the arm 135 The angle between the two is to ensure that the user maintains an equilibrium state on the footrest 140. f As can be seen, the machine 11 101 also embodies the above-described concept of the present invention, and can provide the above technology. The result of the question is that the user is particularly convenient and safe even if the user has only been trained for a short period of time or has only a short skating experience.
