201240699 六、發明說明： 【發明所屬之技術領域】 本發明與運動器材有關’特別是關於一種具有鎖定 機構的樓梯機。 【先前技術】 一般而言，樓梯機的運轉不是由器材主動發起，而 是由使用者的體重驅動，換言之’當使用者登上樓梯 機，樓梯機梯級機構的踏板承受體重負載，體重負載的 斜向分量便會使傳動裝置開始運轉；而習知樓梯機還可 能配置有發電裝置、控制介面、飛輪及ECB(Eddy Current Brake)阻力裝置與傳動裝置連接，當傳動裝置 開始運轉時’ 一併使發電系統開始發電，進而啟動控制 介面’使用者可以藉由控制介面操作ECB阻力裝置而 .調整運動難度。此類樓梯機無論處於使用或閒置狀態， 梯級機構通常無法停止不動，一旦施加負載於其上，梯 級機構便會開始下滑，對於使用者而言較不安全，例 如，一個不熟悉樓梯機的使用者，可能在一登上樓梯機 時，被開始滑動的梯級機構所驚嚇；對於一個慣於使用 樓梯機的使用者，可能在激烈運動時不慎超出自身負 荷，梯級機構又無法緊急停止而發生意外。 基於安全及實用性考量，美國專利第4,687，195號 揭露了 一種機械式速度控制裝置，該速度控制裝置主要 包含樓梯機側面的連桿、與驅動軸相連並且可位移的煞 車鼓、以及與煞車鼓配合的制動瓦，使用者可拉動連桿 201240699 來移動煞車鼓，進而控制煞車鼓與制動瓦的接觸面積， 藉此控制傳動裝置傳動軸的旋轉難易度，當煞車鼓完全 與制動瓦接觸時，傳動轴就無法旋轉，此時，即使使用 者站在踏板上，傳動裝置也無法運轉，藉此達到鎖定樓 梯機梯級機構的效果，然而，此種裝置的缺點在於使用 者可能在運動中不慎踢到連桿，造成使用者在沒有被預 先通知的情況下，梯級機構滑動速度就突然改變而導致 意外，並且，此種裝置無法提供從高速中緊急停止的功 能，舉例而言，若一不熟悉樓梯機的使用者在運動中產 生不適，以美國專利第4,687,195號所揭露的樓梯機， 無論是使用者本身或週遭的人都無法採取安全的救援 動作，若在高速中強行由使用者或使用者以外的人拉動 連桿，因為慣性定律，使用者可能會發生嚴重意外；此 外，此種裝置也無法完全保證每個使用者要登上樓梯機 時，梯級機構皆是固定而無法滑動。 基於上述問題，美國專利第4,927,136號揭露了一 種電磁式速度控制裝置，作法為在傳動裝置上加裝一套 與傳動軸相連的電磁阻力機構，電磁式阻力機構具有一 旋轉軸，該旋轉轴由電磁阻力單元的輸出軸與飛輪同轴 固接而組成，傳動裝置的傳動轴則藉皮帶與若干皮帶輪 與旋轉軸的一端連接；當使用者想要結束運動時，需要 先往上靠近位於機台上側的控制介面並按下控制介面 上的停止紐，此時電磁阻力單元會逐漸鎖定輸出軸，最 後使得旋轉軸難以旋轉，換言之，藉由限制飛輪使得傳 動裝置無法運轉；然而，當使用者處於激烈運動狀態， 通常而言，此時使用者會在踏板上高速跑動，一旦身體 201240699 無法負4 I法勉強自己再加速到更高的速度以克服高 ’也就是使用者自 己已經沒有能力觸及 控制介㈣啟動樓梯機的停止程序，此時，旁人即使想 伸出5手去啟動控制介面上的鎖定功能也會因為樓梯 做到’因此美國專利第4,927，136號同 樣沒有解決使用者本身或旁人在危急時無法救援的問 美國專矛1】宽d „ . , ’

機，都巧在停止程序中針對梯級機構的姿態 制，也就疋同一台樓梯機在每次停止時，梯級機構的踏 板相對於地面的姿態都是隨機變化的，若踏板的姿態不 恰當’例如概呈水平的踏板當中最低的一階仍距離地面 一段高度，可能導致樓梯機上的使用者不容易回到地 面，也會導致下一位使用者需要多花費一些氣力才能登 上樓梯機’因而造成使用不方便。 201240699 【發明内容】 鑑於上述問題，本發明的主要目的在於提供一種具 有鎖定裝置的樓梯機，可提供使用者本身或旁人在需要 時停止樓梯機運轉。 本發明的另一目的在於提供一種在停止運轉過程 中具有梯級機構姿態控制功能的樓梯機，可在停止程序 即將結束時，進一步控制梯級機構相對於地面的姿態， 使得當前使用者容易回到地面，也使得下一位使用可輕 鬆地登上樓梯機。 為了達成前述主要目的，依據本發明提供的一較佳 實施例，前述樓梯機包含有：一架體；安裝於架體的一 傳動裝置；一樓梯裝置，具有若干梯級機構，各梯級機 構並具有一可供踩踏的踏板，梯級機構與傳動裝置連 接，當踏板承受負載時，藉由梯級機構將負載傳遞到傳 動裝置，進而使得傳動裝置開始運轉；一阻力裝置，設 於架體並與傳動裝置連接，具有一飛輪及與控制系統電 性連接的一電控阻力機構，可調整飛輪的旋轉阻力，藉 以控制傳動裝置的運轉速度；一觸發元件，設於前述架 體一預定位置，並且前述預定位置為一使用者本身及/ 或旁人可輕易接近並觸發前述觸發元件的位置；一鎖定 機構，設於前述架體，用以限制並停止前述飛輪的轉 動；一控制系統，設於前述架體，與前述電控阻力機構、 前述觸發元件、前述鎖定機構電性連接，當前述觸發元 件被啟動，可回應前述觸發元件發出的一第一訊號，控 制前述電控阻力機構及鎖定機構停止樓梯機的運轉。 為了達成前述次要目的，前述鎖定裝置更包含一感 6 201240699 應裝置，設於前述架體與樓梯裝置之間，並與前述控制 系統電性連接，用以監測樓梯裝置的姿態，其中，當樓梯 裝置處於一預定姿態時，感應裝置被觸發而發出一第二 訊號，前述控制系統回應前述第二訊號，在適當的時間 點控制前述鎖定機構鎖住飛輪使前述樓梯機停止運轉。 藉由本發明的上揭技術手段，使用者在運動過程中 可由自己及/或旁人來啟動觸發元件而停止樓梯機運 轉，並且，當樓梯機即將停止運轉，且梯級機構的姿態 處於一預定姿態時，樓梯裝置才會被鎖定，如此一來， 無論是樓梯機上的使用者要回到地面，或者是下一位使 用者要登上樓梯機，都可以輕鬆、安全地達成。 【實施方式】 以下即配合附圖詳細說明本發明之較佳實施例的 結構、動作及功效。另外，本說明書中對於機構或其部 位在其位置描述上冠以「前」、「後」、「左」、「右」、「出 口」、「入口」、「上」、「下」等，對應於使用者在操作本 較佳實施例時的空間關係。 如第1至第3圖所示，本發明一較佳實施例的樓梯 機（1)主要包含一架體（10)、安裝於架體（10)的一傳動 裝置（30)、受傳動裝置（30)帶動的一樓梯裝置（20)、一 控制系統（圖中未示）、與傳動裝置（30)配合的阻力裝置 (40)、及與阻力裝置（40)配合的一鎖定機構（50)。 參閱第2圖（相對於第1圖，為了清楚地顯示本較 佳實施例的結構構成，第2圖未顯示殼罩及前述樓梯裝 201240699 置（20))’前述架體主要具有—底座⑴）、—支柱（ι2)、 -支架（13)、左、右第-扶手（14)、纟、右第二扶手 (15)、及-儀錶桿⑽。架體（1())藉底座⑴）設置於一 平面（例如地面）’底座（11)大致為—開σ向後的U形結 構，U形開σ端及其向上延伸的空間形成—出入空間 (R1)，支柱（12)固接於底座（u)前端，並朝前、朝上延 伸；支架（13)則主要包含有左、右第一支撐桿 (131)(132)、左、右第二切桿（133)(134)、及一框架 (135)，且左、右第一支撐桿（131)(132)相對於左、右 第一支撐桿（133)( 134)而言長度較短，其中，左、右第 一支樓桿（131)(132)分別在出人空間（R1)的兩側垂直 地固接於則述底座⑴），左、右第二支樓桿⑷ 則垂直地固接於底座的中間部位，前述框架（135) 則固接於左、右第-支料⑽）（132)的頂部、左、右 支撐桿（133)(134)的頂部、及支柱（12)，因而形成 一攸出入空間（R1)向前、向上延伸的坡面；前述架體 有左、右導軌（17)，分別設於框架（135)頂面的 左二右兩側；前述儀錶桿（16)設於支柱（12)的頂端，用 以女裝控制介面（62)及多媒體介面（61);前述左、右第 一扶手（14)的底部固接於底座（11)，並向後、向上延伸 至出入空間（R1)之後，轉而向前、向上延伸並分別固接 於儀錶桿（16)的左、右兩側；前述左、右第二扶手⑽ 則大致以相同於左、右第一扶手（14)的延伸方向分別固 接於左、右第一扶手（14)和儀錶桿（16)之間。 參閱第2圖及第3圖，前述傳動裝置（3〇)具有一第 201240699 一傳動軸（31)、左、右第一傳動輪（311)(312)、一第二 傳動軸（32)、左、右第二傳動輪（321)(322)、左、右傳 動帶（33)(34)、若干皮帶輪（35)、以及若干皮帶（36); 其中，第一、第二傳動軸（31)(32)以水平軸向分別樞設 於框架（135)的前端和後端部位下側，並且，第一、第 二傳動轴（30(32)的兩端分別固設左、右第一傳動輪 (311)(312)及左、右第二傳動輪（321)(322)，換言之， 第一傳動輪（311)(312)的位置高於第二傳動輪（321) (322)，第一傳動輪（321)(322)較為靠近出入空間 (R1);左、右傳動帶（33)(34)分別套繞於左第一傳動輪 (311)、左第一傳動輪（321)及右第一傳動輪（312)、右 第一傳動輪（322) ’在本較佳實施例中，第一、第二傳 動輪（31 1)(312)(321)(322)採用鏈輪，左、右傳動帶 (33)(34)則為键條’在其他可能的實施例中，亦可能採 用其他等效的零件。 參閱第4圖及第5圖，前述樓梯裝置（2〇)為若干梯 級機構（21)相接而成，本實施例中，梯級機構（21)數量 為八個，各梯級機構（21)主要具有一支撐桿（22)、一踏 板（23)、及一擋板（24)，其中，各支撐桿（22)以平行於 地面的方式固設於左、右傳動帶（33)(34)之間，且各支 撐桿（22)之間的距離相等，踏板（23)與擋板（24)鄰近的 一端以水平軸向互相嵌合，其中並貫穿一連接桿， 踏板（23)的另一端則樞接在屬於同一梯級機構（如）的 支撑桿（22) ’擔板（24)的另-端則樞設於鄰近梯級機構 (20)的切桿（22)，其中，各支撐桿⑽的兩端略微突 201240699 出左、右傳動帶（33)(34)，用以樞設滚輪（26)，並且支 樓桿（22)的左端為一感應部位（53a)，詳細作用容後詳 述；當使用者由出入空間（R1)登上梯級機構（21)的踏板 (23)時’體重便會透過梯級機構（21)傳遞到傳動裝置 (30) ’而驅使樓梯裝置（2〇)開始向下滑動，此時，使用 者需不斷地往前踩踏下一個滑下來的梯級機構（21)，藉 此達到模擬爬樓梯的運動效果，其中，擋板（24)除了用 來連結及支撐踏板（23)，還可防止使用者在運動時腳抬 的不夠高而被下一個梯級機構（21)的踏板（24)所絆 倒。此外’當梯級機構（21)繞過第一傳動輪（311 )(312) 上侧而滑動向下時，各支撐桿（22)的兩端所樞設的滚輪 (26)同時進入對應導軌（π)内，藉此提高樓梯裝置（2〇) 的運轉順暢度和踏板（23)支撐強度。需要特別說明的 是’上述樓梯裝置（20)的機構構成僅是本實施例的實施 方式，'在其他可能的實施例中，樓梯裝置亦可如美國專 利第5,769,759號中所揭示的結構，僅具有踏板，而沒 有類似於本實施例的擋板，但仍然具有若干梯級機構； 顯而易知地，在其他可能的實施例中，熟悉此項領域的 人士應可變化出各種形式的樓梯裝置，但共通點應是皆 具有若干梯級機構，且各梯級機構均具有供踩踏的踏板 或其均等結構。 參閱第2圖及第3圖，前述阻力裝置（40)藉著若干 隔板（18)設於架體（1〇)，阻力裝置（40)具有一飛輪（41) 及一電控阻力機構（42)，飛輪（41)樞設於隔板（18)，藉 由若干皮帶（36)及大小不一的皮帶輪（35)與第一傳動 201240699 輪（311)相連，當傳動裝置（30)運轉時，透過各皮帶輪 (35)和皮帶（36)帶動飛輪（41)旋轉，在本較佳實施例 中’飛輪（41)是由皮帶（36)與皮帶輪（35)的連接形成三 級傳動而帶動飛輪旋轉，然而，皮帶（36)、皮帶輪（35)、 飛輪（41)的安排和速比關係為公知技術，其他可能實施 例中亦能因需求不同而採用形式上不同、實質精神相同 的速比關係’在此不多贅述；另外，在飛輪（41)周面的 前後兩侧設有電控阻力機構（42)，可受控制系統控制而 利用電磁效應控制飛輪（41)的旋轉速度，本較佳實施例 中’電控阻力機構（42)包含一對電磁鐵（421)，分別設 於飛輪（41)的前侧及後侧，各電磁鐵（421)的右側設有 一風扇（422)，可在控制飛輪（41)速度的過程中進行散 熱，至於電磁鐵（421)如何影響飛輪的旋轉速度以及電 磁鐵（421)的其他專效機構（例如ECB阻力機構）均屬於 習知技術，在此不加以贅，述。 參考第1圖，控制介面（61)可顯示樓梯機（1)的各 項參數供使用者觀看，如樓梯裝置（2〇)的速度SPM (step per minute)、運動時間、運動量等等，當使用者雙 手握在設於第一扶手（15)的心跳握把（63)時，控制介面 (61)亦可顯示使用者的心跳數，另外，控制介面（61) 與剞述電控阻力機構（42)電性連接，使用者可在控制介 面（61)上§周整阻力而使樓梯機（1)可以提供合適的運動 強度，此外，控制系統也具有多媒體介面（62),例如安 裝於控制介面（61)上方的電視’可讓使用者在運動時觀 員多媒體内谷’在本較佳實施例中，控制系統還包含了 201240699 解鎖/鎖定前述樓梯裝置（20)的功能，相關的系統配置 及操作方式容後詳述。此外，控制系統還包含了 一速度 感測單元（64)，設於傳動裝置（30)，用以提供一訊號給 控制系統，使得控制系統可經由計算而得知當前傳動裝 置（30)的速度（30)，本實施例中採用一轉盤式編碼器， 主要具有一碼盤與光感測器（圖中未示），此為習知技 術，細節不多加贅述；控制系統可藉由速度感測單元（64) 及阻力裝置（40)自動地調整樓梯裝置（20)的運轉速 度，舉例而言，一位體重較輕的使用者與一位體重較重 的使用者所能提供給傳動裝置（30)的斜向負載不同，如 果一樓梯機不具有自動調整的功能，上述兩位使用者將 較難維持在同一速度進行運動，如果藉由本實施例的控 制系統，當體重較重的使用者運動時可能容易使得樓梯 裝置滑下速度過快，此時，控制系統可自動地控制阻力 裝置（40)，加大出力而減慢速度，讓速度維持在一預定 速度；在體重較輕的使用者運動時則可減少阻力裝置 (40)的出力，使得樓梯裝置的滑下速度較容易上升至預 定速度，樓梯機（1)因此而可以穩定地運轉。 如第3圖所示，前述鎖定機構（5 0)設於前述隔板 (18)，與飛輪（41)同軸並與控制系統電性連接，可受控 制系統控制而鎖定飛輪（41)，使飛輪無法旋轉，相較於 阻力機構（40)在本實施例中主要被應用於漸進式地調 整飛輪（41)的旋轉速度，鎖定機構（50)的主要功能在於 完全鎖住飛輪（41)，不讓飛輪（41)旋轉，在本實施例 中，鎖定機構（50)為一電磁機械煞車器，包含有線圈單 201240699 元、彈簧、電樞板、固定板、煞車片、及一釋放手把（51)， 其中’煞車片與飛輪（41)的軸心同軸固接’可與飛輪（41) 一同旋轉，當電磁機械煞車器沒有接收到電力時，線圈 單元無法產生激磁反應，電樞板僅受到彈簧的彈力推擠 而被壓向固定板，此時，煞車片會被電樞板和固定板咬 合，藉此，固定飛輪（41)軸心進而限制飛輪（41)使其無 法轉動；當電磁機械煞車器通電時，線圈單元產生激磁 反應，吸引電樞板對抗彈簧的彈力並壓制彈簧，此時， 煞車片便會被釋放，飛輪（41)因此而得以自由轉動；此 外，若有維修需求時，須在斷電狀態時解鎖飛輪（41)， 可透過扳動前述電磁機械煞車器的釋放手把（51)，強行 將電樞板與固定板鬆開，使得煞車片與飛輪（41)可自由 轉動；因上述或類似電磁機械煞車器為習知技術且市面 上產品眾多，在此僅作簡略說明，圖中亦未詳加展示。 如第4圖所示，觸發元件（52)設於出入空間（ri) 内位於地面的踏墊（27)内，旁人（例如教練）可輕易接近 踏墊（27)，觸發元件（52)並與控制系統電性連接，當 觸發元件（52)被觸發時，可提供控制系統一第—訊號， 當控制系統接受到此一訊號，即回應第一訊號並開始進 行一停止程序（容後詳述），最後命令前述鎖定機構（51) 鎖住飛輪（41)，而達到限制樓梯裝置（2〇)使其無法滑動 的效果，在本實施例中，觸發元件（52)為一電容式威測 元件，没於出入空間（R1)的地面上的一踏塾（27)内，電 容式感測元件具有一觸發範圍，在觸發範圍内可偵測是 否有物體（例如人體）接近，舉例而言，當使用者戈旁人 201240699 直接踩踏踏墊（27)或跨越踏墊（27)都可以將其觸發。需 要特別說明的是，在本實施例中，使用者無法透過觸發 觸發元件（52)來解鎖樓梯裝置（2〇)，舉例而言，當鎖定 機構（51)沒有接受電力時，也就是樓梯機（丨）處於待機 狀態時，樓梯裝置（20)處於鎖定狀態，此時，當一使用 者要使用本實施例的樓梯機（丨），無論是跨越過踏墊 (27)、或者先踩踏踏墊（27)再登上樓梯裝置（2〇)的踏板 (23)，雖然觸發元件（52)被啟動’也發送訊號給控制系 統，但使用者無須擔心樓梯裝置（2〇)是否已解鎖，使用 者惟有透過控制介面（61)的解鎖功能才能將樓梯裝置 (20)解鎖並進行運動；在運動過程中，若使用者產生不 適而需緊急鎖定樓梯裝置（20)，可以自行啟動控制介面 (61)所提供的停止程序（例如按下ST〇p鈕（圖中未示）） 而鎖定樓梯裝置（2〇)，若無力觸及控制介面（61)，也可 以由旁人（例如教練）靠近或踩踏踏墊（27)來啟動觸發 兀件（52)進行停止程序而鎖定樓梯裝置（2〇);若使用者 順利地結束運動，可以透過啟動控制介面（61)的停止程 序來鎖定樓梯裝置（20)，萬--時疏忽，沒有啟動停止 程序就退出樓梯裝置（20)，當使用者跨越或踩踏踏墊 (27)時，同樣地，觸發元件（52)會發送訊號通知控制系 統進行停止程序，換言之，無論使用者有無意識到結束 運動刖要鎖定樓梯裝置（20)，本實施例皆可自動地將樓 梯裝置（20)回復到鎖定狀態，確保每位使用者要登上樓 梯枝日守，都可以踩在固定不動的踏板（23)上，從容地做 好準備才啟動解鎖功能開始進行運動。 14 201240699 本發明的發明精神之一在於觸發元件設置於架體 Λ近知述出入空間且使用者及/或旁人可輕易接近的一 預定位置，而且預定位置不是位於樓梯機相對於地面的 高處’而是通常使用者的身高就可以接近的位置，或者 正常的運動模式下可以方便地接觸的地方，舉例而言， 如本實施例的踏墊（27)，或者在其他可能實施例中（圖 中未示），可能將觸發元件設於第一扶手（14)或第二扶 手（15)靠近出入空間（R1)的位置，此種實施例可讓使用 者即使在超出本身負何的情形下，亦即無法靠近控制介 面（61)而啟動控制介面（μ)的鎖定功能，也可以輕易地 碰觸第一扶手（14)或第二扶手（15)來啟動停止程序；觸 發元件（52)也可能設於樓梯機（1)的側邊外殼、第一、 第二扶手（14)(15)的中間段等等，因可安裝的位置視需 求有眾多選擇且都可以具有如上所述的發明精神，在此 不'--歹舉-。 -- · 本實施例將觸發元件（52)設於出入空間（R1)的踏 墊（27)中’正常來說，使用者要登上或退出樓梯機（d 時都會經過出入空間（W )，觸發元件（52)設於此可以有 效地發揮功能，此外，由於觸發元件（52)接近地面，當 要實施緊急救援行動時，旁人可以方便地直接踩踏踏墊 (27)而啟動觸發元件（52)進而緊急停止樓梯機（1)。 觸發件（52)也有可能採用其他同樣具有近距感 測（Proximity sensing)功能的電子元件，例如電阻式、 電感式、或光學式等如感測元件’或者其他具有感測 物體通過功能的裝置，無論是採用感測元件内部的參數 15 201240699 因物體接近而改變的裝置，或所發出的光波、聲波、磁 場、或電磁波受到遮斷、改變傳導面積才會觸發的感測 元件均屬此類’舉例而言，在一可能實施例中，將紅外 線感測器（主/被動式）設於第一或第二扶手靠近出入空 間的部位’使用者登上或退出樓梯機都必定會觸發紅外 線感測器；當然，觸發元件（52)也可以採用需要直接接 觸（例如：按壓）才能啟動的電子元件。 參考第4圖’感應裝置（53)亦與控制系統電性連 接’當樓梯裝置（20)相對於架體（1〇)處於一預定姿態 時’就會觸發感應裝置（53)，藉此’在前述停止程序中， 感應裝置（53)可以輔助控制系統判斷何時可以命令鎖 定機構（51)鎖住樓梯裝置（2〇)，目的在於使樓梯裝置 (20)停止時，踏板（23)可以定止在使用者容易登上或走 下樓梯機（1)的角度。舉例而言，如第7圖所示，一梯 級機構正準備繞過左、右第二傳動輪，—其所屬，的踏板（23) 幾乎垂直於地面，若樓梯裝置（20)此時被鎖住了，使用 者無論是要走下樓梯裝置（20)或登上樓梯裝置（2〇)，都 需要克服踏板⑵）加上擔板⑽這—頗令人為難的高 度’對比於第1圖（並參考第4圖）’圖中所示為感應裝 置（53)在彳τ止程序中發揮功能時，樓梯裝置（2〇)被鎖定

裝置（20)之間’具有一感應元件（53b)及前述感應部位 (53a)’感應元件（53b)在本實施例中為一感應型近接咸 測元件（在感測器的領域中，或稱「感應型近接開關 (Proximity Switch)」），以作動原理而言，為—電磁式 的感測元件，設於左第二傳動輪（321)左側前下方的架 體（10)，且位置大致對應於左傳動帶（33)的繞轉軌跡， 感應部位（53a)則位於各梯級機構（21)的支撐桿（22)左 端且與左傳動帶（33)連結，本實施例中具有八個感應部 位（53a)，且各感應部位（53a)之間的距離相等，以第4 圖為例，—感應部位（53a)隨著左傳動帶移動到感應單 兀（53b)的位置’以左侧視圖而言，該感 =形應式單:咖所你其中，為配合感應元件 . 本貫施例中的感應部位（53a)由導磁物質 ⑽亦為桿（22)的左端為導磁物質，甚至滾輪

Description of the Invention: [Technical Field of the Invention] The present invention relates to sports equipment, particularly to a stair machine having a locking mechanism. [Prior Art] In general, the operation of the stair machine is not initiated by the equipment, but by the weight of the user. In other words, when the user climbs the stair machine, the pedal of the stair step mechanism is subjected to the weight load and the weight load. The slanting component will cause the transmission to start running; and the conventional derrick may also be equipped with a power generating device, a control interface, a flywheel and an ECB (Eddy Current Brake) resistance device connected to the transmission, when the transmission starts to run together The power generation system starts to generate electricity, and then the control interface is activated. The user can operate the ECB resistance device through the control interface. Adjust the difficulty of exercise. Such a stair machine can not be stopped regardless of whether it is in use or idle. Once the load is applied thereto, the step mechanism will start to slide down, which is less safe for the user, for example, an unfamiliar use of the stair machine. It may be frightened by the stepping mechanism that started to slide when it is boarded; for a user who is used to using the stair machine, it may accidentally exceed its own load during intense exercise, and the step mechanism cannot be stopped urgently. accident. A mechanical speed control device is disclosed in U.S. Patent No. 4,687,195, which is incorporated herein by reference. The drum-fitted brake shoe, the user can pull the connecting rod 201240699 to move the brake drum, thereby controlling the contact area between the brake drum and the brake shoe, thereby controlling the rotation difficulty of the transmission shaft, when the brake drum is completely in contact with the brake shoe The drive shaft cannot be rotated. At this time, even if the user stands on the pedal, the transmission cannot operate, thereby achieving the effect of locking the stair step mechanism. However, the disadvantage of such a device is that the user may not be in motion. Carefully kicking the connecting rod, causing the user to suddenly change the sliding speed of the step mechanism without prior notice, and the device cannot provide the function of emergency stop from high speed. For example, if A user unfamiliar with the stair machine is uncomfortable during exercise, as disclosed in U.S. Patent No. 4,687,195. The stair machine, no matter the user or the people around him, can't take safe rescue action. If the link is pulled by the user or the user at high speed, the user may have a serious accident because of the law of inertia. In addition, such a device cannot fully guarantee that each stepper is fixed and cannot slide when each user wants to board the stair machine. Based on the above-mentioned problem, an electromagnetic speed control device is disclosed in U.S. Patent No. 4,927,136, which is an electromagnetic resistance mechanism connected to a transmission shaft, and the electromagnetic resistance mechanism has a rotary shaft. The output shaft of the electromagnetic resistance unit is coaxially fixed with the flywheel, and the transmission shaft of the transmission is connected to one end of the rotating shaft by a belt and a plurality of pulleys; when the user wants to end the movement, the user needs to go up to the machine first. The control interface on the upper side presses the stop button on the control interface. At this time, the electromagnetic resistance unit gradually locks the output shaft, and finally makes the rotating shaft difficult to rotate. In other words, the transmission is disabled by restricting the flywheel; however, when the user is at In a state of intense exercise, usually, the user will run at high speed on the pedal. Once the body 201240699 is unable to bear the 4 I method, he will accelerate himself to a higher speed to overcome the high', that is, the user has no ability to touch. Control (4) start the stop procedure of the stair machine, at this time, even if the person wants to extend 5 hands Locking function on the control interface will start as the stairs to do 'so the United States Patent No. 4,927,136 likewise does not address the users themselves or others at the time of emergency rescue and asked the United States not specifically spear 1] width d ". , '27,136 also revealed that the tension sensing element can be mounted on the rotating shaft two i1Ϊ: ί on the belt' by this judgment:: two;: = judge no user, sensing - eclipse - 屮 U, ^ Control system, control system controls electromagnetic resistance single user: get = the mechanism is locked, the intention is to start the exercise 1 # & ground, field elevator. #User is ready to unlock the button, the first step on the helmet and the axis on the control interface, the pedal will start to slide 〇" * Female, whether it is a conventional or the aforementioned US plane, is in the stop program For the attitude system of the step mechanism, the attitude of the step mechanism relative to the ground is randomly changed every time the same stair machine stops, if the attitude of the pedal is not appropriate, for example, the lowest level of the pedal is The first step is still a certain height from the ground, which may cause the user on the stair machine to not easily return to the ground, and the next user may need to spend more effort to board the stair machine, thus making the use inconvenient. 201240699 SUMMARY OF THE INVENTION In view of the above problems, it is a primary object of the present invention to provide a stair machine having a locking device that can provide the user himself or a nearby person to stop the operation of the stair machine when needed.

It is to be noted that the structure of the above-mentioned stair device (20) is only an embodiment of the present embodiment. In other possible embodiments, the stair device can also be constructed as disclosed in U.S. Patent No. 5,769,759. There are pedals, but there are no baffles similar to the present embodiment, but still have a number of step mechanisms; it will be apparent that in other possible embodiments, those skilled in the art should be able to vary the various types of stair devices. However, the common point should have a plurality of step mechanisms, and each step mechanism has a pedal for pedaling or its equal structure. Referring to Figures 2 and 3, the resistance device (40) is disposed on the frame body (1) by a plurality of partitions (18), and the resistance device (40) has a flywheel (41) and an electrically controlled resistance mechanism ( 42) The flywheel (41) is pivoted to the partition (18) and connected to the first transmission 201240699 wheel (311) by a plurality of belts (36) and pulleys (35) of different sizes, when the transmission (30) is operated When the flywheel (41) is rotated by the pulleys (35) and the belts (36), in the preferred embodiment, the flywheel (41) is connected by a belt (36) and a pulley (35) to form a three-stage transmission. Driving the flywheel to rotate, however, the arrangement of the belt (36), the pulley (35), the flywheel (41) and the speed ratio relationship are well-known techniques, and other possible embodiments can also adopt different forms and substantially the same spirit due to different needs. The speed ratio relationship is not described here; in addition, an electronically controlled resistance mechanism (42) is provided on the front and rear sides of the flywheel (41), which can be controlled by the control system to control the rotational speed of the flywheel (41) by electromagnetic effect. In the preferred embodiment, the electronically controlled resistance mechanism (42) includes a pair of electromagnets (42). 1), respectively disposed on the front side and the rear side of the flywheel (41), and a fan (422) is disposed on the right side of each electromagnet (421), which can dissipate heat during the process of controlling the speed of the flywheel (41), as for the electromagnet ( 421) How to affect the rotational speed of the flywheel and other special mechanisms of the electromagnet (421) (such as the ECB resistance mechanism) are all known techniques, and will not be described here. Referring to Figure 1, the control interface (61) can display various parameters of the stair machine (1) for the user to watch, such as the speed of the stair device (2 〇) SPM (step per minute), exercise time, amount of exercise, etc. When the user holds the heartbeat grip (63) provided on the first armrest (15), the control interface (61) can also display the number of heartbeats of the user, and the control interface (61) and the electronic control resistance The mechanism (42) is electrically connected, and the user can adjust the resistance on the control interface (61) so that the stair machine (1) can provide suitable exercise intensity. In addition, the control system also has a multimedia interface (62), for example, installation. The TV above the control interface (61) allows the user to view the multimedia valley during the movement. In the preferred embodiment, the control system further includes the function of unlocking/locking the aforementioned stair device (20) in 201240699, The system configuration and operation mode are detailed later. In addition, the control system further includes a speed sensing unit (64) disposed on the transmission (30) for providing a signal to the control system, so that the control system can know the speed of the current transmission (30) through calculation. (30) In this embodiment, a rotary encoder is used, which mainly has a code wheel and a light sensor (not shown). This is a conventional technique, and details are not described in detail; the control system can be sensed by speed. The measuring unit (64) and the resistance device (40) automatically adjust the running speed of the stair device (20), for example, a light weight user and a heavier user can provide the transmission (30) The oblique load is different. If a stair machine does not have the function of automatic adjustment, the above two users will be more difficult to maintain the same speed for movement. If the control system of this embodiment is used, the weight is heavy. The movement may easily cause the stair device to slide down too fast. At this time, the control system can automatically control the resistance device (40), increase the output to slow down the speed, and maintain the speed at a predetermined speed; Can reduce the resistance means (40) is output when the user moves a lighter weight, such that the speed of sliding down stairs apparatus relatively easily increased to a predetermined speed, the staircase (1) and thus can be stably operated. As shown in FIG. 3, the locking mechanism (50) is disposed on the partition plate (18), coaxial with the flywheel (41) and electrically connected to the control system, and can be controlled by the control system to lock the flywheel (41). The flywheel cannot rotate. Compared with the resistance mechanism (40), in this embodiment, it is mainly used to progressively adjust the rotational speed of the flywheel (41). The main function of the locking mechanism (50) is to completely lock the flywheel (41). In the present embodiment, the locking mechanism (50) is an electromagnetic mechanical brake device, including a coil single 201240699 yuan, a spring, an armature plate, a fixed plate, a brake shoe, and a release handle. (51), wherein the 'axis of the car and the axis of the flywheel (41) is coaxially fixed' can be rotated together with the flywheel (41). When the electromagnetic mechanical brake does not receive power, the coil unit cannot generate an excitation reaction, and the armature plate It is pressed against the fixing plate only by the elastic force of the spring. At this time, the brake piece is engaged by the armature plate and the fixed plate, thereby fixing the axis of the flywheel (41) and thereby restricting the flywheel (41) from rotating. When the electromagnetic mechanical brake is energized, The coil unit generates an excitation reaction, attracting the armature plate against the spring force of the spring and pressing the spring. At this time, the brake shoe will be released, and the flywheel (41) can be freely rotated. In addition, if there is maintenance demand, the power supply must be powered off. In the state, the flywheel (41) is unlocked, and the armature plate and the fixed plate are forcibly released by pulling the release handle (51) of the electromagnetic mechanical brake device, so that the brake piece and the flywheel (41) are freely rotatable; Or similar electromagnetic mechanical brakes are known in the art and there are many products on the market, which are only briefly described herein, and are not shown in detail in the drawings. As shown in Fig. 4, the triggering element (52) is disposed in the mat (27) on the ground in the access space (ri), and a person (such as a coach) can easily access the mat (27) and trigger the component (52). Electrically connected to the control system, when the triggering component (52) is triggered, a first signal of the control system can be provided. When the control system receives the signal, the first signal is responded to and a stop procedure is started. Finally, the locking mechanism (51) is finally commanded to lock the flywheel (41), and the stair device (2〇) is prevented from sliding. In this embodiment, the triggering element (52) is a capacitive type. The measuring component is not in a pedal (27) on the ground of the access space (R1), the capacitive sensing component has a trigger range, and it is possible to detect whether an object (such as a human body) is approaching within the trigger range, for example In other words, when the user Kobe 201240699 directly step on the mat (27) or across the mat (27), it can be triggered. It should be particularly noted that in this embodiment, the user cannot unlock the stair device (2〇) by triggering the triggering element (52). For example, when the locking mechanism (51) does not receive power, that is, the stair machine (丨) When in the standby state, the stair device (20) is in a locked state. At this time, when a user wants to use the stair machine (丨) of the embodiment, whether it is crossing the tread pad (27), or stepping on the tread first The pad (27) is then mounted on the pedal (23) of the stair device (2). Although the triggering element (52) is activated to send a signal to the control system, the user does not have to worry about whether the stair device (2〇) has been unlocked. The user can unlock and move the stair device (20) only through the unlocking function of the control interface (61); during the movement, if the user has an uncomfortable need to urgently lock the stair device (20), the control interface can be activated by itself ( 61) The stop program provided (for example, pressing the ST〇p button (not shown)) and locking the stair device (2〇), if it is unable to touch the control interface (61), it can also be approached by another person (such as a coach) or Step on The stepping pad (27) activates the triggering member (52) to stop the program and locks the stair device (2〇); if the user smoothly ends the movement, the stair device can be locked by the stopping program of the starting control interface (61) (20) ), 10,000-time negligence, exiting the stair device (20) without starting the stop program, when the user crosses or steps on the mat (27), similarly, the triggering component (52) sends a signal to inform the control system to stop the program. In other words, whether the user is aware of the end of the movement and wants to lock the stair device (20), the embodiment can automatically return the stair device (20) to the locked state, ensuring that each user has to climb the stairs. , you can step on the fixed pedal (23), ready to start the unlock function to start the exercise. 14 201240699 One of the inventive spirits of the present invention is that the triggering element is disposed at a predetermined position in which the frame body is close to the access space and is easily accessible to the user and/or others, and the predetermined position is not located at a height of the stair machine relative to the ground. 'Rather, a position that is generally accessible to the user's height, or a place that can be easily accessed in a normal sport mode, for example, a tread pad (27) of the present embodiment, or in other possible embodiments ( Not shown in the figure), the triggering element may be disposed at a position where the first armrest (14) or the second armrest (15) is close to the access space (R1). Such an embodiment allows the user to exceed the situation of himself or herself. Next, that is, the locking function of the control interface (μ) cannot be started close to the control interface (61), and the first armrest (14) or the second armrest (15) can be easily touched to start the stopping procedure; the triggering component (52) It may also be located in the side casing of the stair machine (1), the middle section of the first and second armrests (14) (15), etc., since the mountable position has many options as needed and may have the above of Ming spirit, which is not '- bad move -. -- This embodiment sets the triggering element (52) in the step (27) of the access space (R1). Normally, the user has to climb or exit the stair machine (d will pass through the access space (W) The triggering element (52) is provided here to function effectively. In addition, since the triggering element (52) is close to the ground, when an emergency rescue operation is to be performed, the person can conveniently step on the mat (27) and activate the triggering element ( 52) Further stop the stair machine (1). It is also possible for the trigger member (52) to use other electronic components that also have a proximity sensing function, such as a resistive, inductive, or optical type such as a sensing element. 'Or other devices that have the function of sensing the passage of the object, whether it is a device that changes the internal parameters of the sensing element 15 201240699 due to the approach of the object, or the emitted light wave, sound wave, magnetic field, or electromagnetic wave is blocked, and the conduction area is changed. The sensing elements that are triggered are all of this type. For example, in one possible embodiment, the infrared sensor (active/passive) is placed near the first or second armrest. The location of the space 'the user will trigger the infrared sensor when boarding or exiting the stair machine; of course, the trigger element (52) can also use electronic components that require direct contact (eg, pressing) to activate. Refer to Figure 4' The sensing device (53) is also electrically connected to the control system. 'When the stair device (20) is in a predetermined posture with respect to the frame (1), the sensing device (53) is triggered, thereby 'in the aforementioned stopping procedure The sensing device (53) can assist the control system in determining when the locking mechanism (51) can be commanded to lock the stair device (2), so that the pedal (23) can be fixed to the user when the stair device (20) is stopped. Ascending or descending the angle of the stair machine (1). For example, as shown in Fig. 7, a step mechanism is preparing to bypass the left and right second transmission wheels, and the pedal (23) to which it belongs is almost vertical On the ground, if the stair device (20) is locked at this time, the user needs to overcome the pedal (2) plus the plate (10) whether he wants to go down the stair device (20) or climb the stair device (2〇). - quite embarrassing height Compared with Figure 1 (and refer to Figure 4), the figure shows that the sensing device (53) functions in the 彳τ stop program, and the stair device (2〇) is locked The left and right second transmission wheels (321) (322) and the pedals (23) above the left and right second transmission wheels (321) (322) are substantially at an angle of 2Q with respect to the horizontal plane, at this time, regardless of the user • a·Up or down the stair device (2〇), it is relatively convenient to raise the foot only to the height of the roughly-half of Figure 7. 16 201240699 As shown in Fig. 4, the 'induction device (53) is provided between the frame body (1〇) and the stair device (20) 'having an inductive element (53b) and the aforementioned sensing portion (53a)' sensing element (53b) In this embodiment, it is an inductive proximity sensing component (in the field of sensors, or "inductive proximity switch"), in terms of actuation principle, is - electromagnetic sensing The component is disposed on the frame body (10) on the left front side of the left second transmission wheel (321), and the position substantially corresponds to the winding track of the left transmission belt (33), and the sensing portion (53a) is located in each step mechanism (21) The left end of the support rod (22) is connected to the left belt (33). In this embodiment, there are eight sensing portions (53a), and the distance between the sensing portions (53a) is equal. Taking FIG. 4 as an example, The sensing portion (53a) moves to the position of the sensing unit (53b) as the left belt moves. In the left side view, the feeling = the shape of the single type: in the coffee room, in order to cooperate with the sensing element. The sensing portion (53a) in the present embodiment is composed of a magnetic conductive substance (10) which is also a magnetic conductive substance at the left end of the rod (22), and even a roller such as a composite material. When the stair machine is running, the left side belt (33) of the sensing part is operated, and the sensing unit is triggered one by one (the sensing range of 53m > the mother sensing part (10)) enters the sensing element (53b) to the control system. The device (cafe) is triggered and returns a trigger in the second message, and the program stops once it is started, for example, on the mat (27). The first right ^ (52) is triggered, and when the control system monitors to the left and ^ ^ m is in a low speed state, the signal returned after being triggered by the device (30) is matched with the current transmission 汹a, Speed, calculate the locking mechanism such as the wheel (41) and stop the stair device (2〇) operation at an appropriate time point, and stop the 201240699 «%, as shown in Figure 1, the step mechanism (21) In a predetermined posture, for example, the posture of the pedal (23) closest to the ground among the pedals (23) of the present embodiment can be controlled to be within the horizontal positive and negative degrees at the time of the stop. 'In general, most staircraft's pedals are separated from the pedals by the same distance' and the stairway is composed of a series of cascade mechanisms. Therefore, as long as the attitude of the cascade mechanism is controlled, the whole ladder device can be controlled. Attitude, so in other possible embodiments, the mounting position of the sensing element ^ may not be the above position shown in this embodiment, and the sensing element may not be the number of electromagnetic 'inductive parts, nor is it a certain amount = the spirit of the present invention One of them is the position and nature of the sensing part of the sensing element. The person, and /, sends a η· /, so that the sensing part is touched every time and represents that the stair device at this time is in a predetermined posture, for example, in other possibilities _ is a light sensing element, located in In the upper e case, the 711 parts may be induced and the sensing part may be the middle part of the step machine pole (133). The light sensing component is matched with the light interruption and the position and the property are selected by the second choice. Rod (10)) will trigger ^, whenever the step mechanism is triggered by the left component, it means that the building I should be 70 pieces 'and' each time; as for the number of sensing parts 4 is placed in the same reservation The posture is corrected by the setting of the control system. The trigger frequency of ^ can be used to control the attitude of the step mechanism in the sequence. It can be stopped in the stair machine to make it easy for the user to enter or exit. When the stair machine stops, the pedal is further. This embodiment not only sets the angle. Easy access position, more = component (10) is set in the lighter s cow (52) set in the mat (27) on the ground of the entrance and exit 18 201240699 space (R1), so that when the user is at the end of the exercise When the stair machine (1) is not stopped through the control interface (61), the stair machine (丨) is directly exited when the movement speed is slow. At this time, as long as the user exits the stair machine from the access space (R1), with or without Stepping on the mat (27) 'The stair machine (1) can be automatically locked in the next few seconds, and the attitude control of the step mechanism (21) can be performed during the process, so that the next user can easily board The stair machine (1) starts to move without the inconvenience of the next user due to the improper operation of the previous user. Next, please refer to FIG. 6 to illustrate the processing flow of the foregoing stair machine (1) stopping program in the embodiment. In general, in order to balance safety and speed, the receiving of the stop command from the control system to the stair machine (1) is stopped and Locking 'the entire stop program will be completed in a few seconds. In this embodiment, the program time for stopping the program is about 8 seconds. In detail, corresponding to step 1 (S1) in the flowchart, whether the user issues a stop command through the control interface (61), or the other person issues a stop command by the trigger element (52) even in In other possible embodiments, 'a stop command may be issued by the heartbeat grip (63) or the first and second armrests (14) (15), which are considered the same in terms of the control system's angle. , that is, the execution of the stop program is started; corresponding to step 2 (S2) in the flowchart, at this time, the control system increases the output of the electronically controlled resistance mechanism (42), and proceeds to step 3 (S3) to continuously transmit the speed sensing. The unit (64) monitors the rotational speed of the transmission (30) for the purpose that the sliding speed of the step mechanism (21) can be gradually lowered to below a predetermined speed. In the present embodiment, the predetermined speed is the left and right first transmissions 19 The rotation speed of the 201240699 wheel is 25 rpm (25 RPM); refer to step 4 (S4) and step 6 (S6) 'When the speed decreases below the aforementioned predetermined speed, and the control system monitors the stair machine to be lower than the reservation Low speed continuous operation (In this embodiment, 1 second), at this time, the control system performs step 7 (S7), the control system starts to refer to the number fed back by the sensing element (53) 3), and calculates the control flow at an appropriate time point. Proceed to step 8 (S8), at this time, the control system increases the output of the electronically controlled resistance mechanism (42) to the maximum, in order to gently lower the sliding speed of the step mechanism (21) to near stop, and simultaneously open the locking mechanism (51) Locking the flywheel (41)' indirectly stops the step mechanism (21) from sliding; due to the completion of step 7 (S7), when step 8 (S8) is completed, the first step pedal for the user ( 23) will be fixed within 2 degrees of positive and negative; refer to step 9 (S9), after the locking mechanism (51) is turned on for a predetermined time, the electronically controlled resistance mechanism (42) still maintains the maximum output, the intention is to avoid When the locking mechanism (51) is just starting to work, it may happen that the brakes are insufficient. In the case of insurance and safety, the electronically controlled resistance mechanism (42) and the locking mechanism (51) are simultaneously operated & described for a predetermined time. In the present embodiment, the predetermined time is a shift, one second later' The stop program proceeds to step 1 (s1), and the control system turns off the electronically controlled resistance mechanism (42); then proceeds to step 11 (S11) to complete the stop procedure. In addition, if there are special circumstances, such as the electronic control resistance mechanism (42) failure, this will cause the stop program to fail to reduce the speed at step 彳 (10). U it pre-speed 'At this time' the stop program will proceed to step 5 (= 'In the present embodiment' (4) The system will continuously monitor whether the speed is higher than the month. The time for the predetermined speed is greater than 8 seconds. If the time exceeds 8 20 201240699 seconds, the stop program will skip step 6 (S6) and In step 7 (S7), steps 8 (S8), 9 (S9), 10 (S10), and ll (S11) are directly executed to forcibly stop and lock the stair machine (1), although the pedal cannot be controlled in this special case ( 23), but still can ensure that the stair machine (1) provided in this embodiment can be locked. In other possible embodiments, there may not be a function to control the attitude of the stair device, in this case, the stop program can ignore the steps 7(S7) 'Go directly from step 6 (S6) to step 8 (S8). In a very special case, that is, the user does not start the stop program through the control interface (61), nor does it pass through the access space (ri). Exit the stair machine (1), once the user leaves When the stair device (20) does not receive the load, the sliding speed will gradually slow down to stop. At this time, the control system is informed by the speed sensing unit (64) that the current speed is zero, and the locking mechanism (51) will be controlled. The flywheel (41) is locked. Similarly, in such a very small number of examples, the angle of the 'pedal (23) cannot be controlled to a predetermined posture, but this embodiment can still ensure that the stair machine (1) is in a locked state. 21 201240699 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a preferred embodiment of the present invention; FIG. 2 is a perspective view of a preferred embodiment of the present invention corresponding to FIG. 1 except that the cover and the stair device are removed; 3 is a perspective view of a transmission device, a resistance device, and a locking device according to a preferred embodiment of the present invention; and FIG. 4 is a left side view of the present invention in accordance with a first embodiment of the present invention; 5 is an exploded view of a part of a step mechanism in a preferred embodiment of the present invention; FIG. 6 is a flow chart of a stop program according to a preferred embodiment of the present invention; and FIG. 7 is another embodiment of the present invention.
