Description

用於運動器材的具有磁性煞車之緊急停止
本發明涉及用於運動器材的具有磁性煞車之緊急停止。
有氧運動是一種普遍形式的運動，有氧運動藉由降低血壓來改善一個人的心血管健康並對人體提供其他的好處。有氧運動一般涉及在長持續時間中的低強度體力消耗。通常，人體可充分地供應足夠的氧氣，以在有氧運動所涉及的強度等級來滿足身體的要求。常見的有氧運動形式包括跑步、慢跑、游泳及自行車及其他活動。反之，無氧運動通常涉及在短持續時間中的高強度運動。無氧運動的常見形式包括力量訓練及短距離跑步。
許多人選擇在室內進行有氧運動，例如在健身房或他們的家裡。通常，使用者使用有氧運動機以在室內進行有氧訓練。這樣類型的一種有氧運動機是固定式自行車。一般而言，固定式自行車包括阻力機構，該阻力機構抵抗在曲柄組件中的腳踏板的旋轉。允許使用者在室內進行有氧運動的其他常見運動機包括橢圓機、划船機、踏步機，及跑步機等等。
一種類型的固定式自行車是描述於發行給Jonathan B. Watt的美國專利第8,585,561號。在此參考文獻中，運動自行車被描述為包括磁性煞車系統，以抵抗飛輪的旋轉。磁性煞車系統可為被安裝在支架上的磁鐵，該等支架相對於框架而選擇性地樞轉，以增加或減少抵抗飛輪旋轉的阻力。支架可利用煞車調整組件來樞轉，該煞車調整組件結合到支架上，使得抵抗飛輪旋轉的磁性力量是在煞車調整組件的調整範圍的至少一部分上以等比例的方式增加或減少。隨著摩擦煞車墊接合飛輪，磁鐵也與飛輪重疊。因此，除了抵抗飛輪旋轉的摩擦力施加至飛輪之外，飛輪的旋轉也由渦流煞車抵抗。由於這個額外的渦流煞車力，對於給定的迴轉速(cadence)而言，要在給定的時間期間內使得摩擦煞車停止飛輪所需要在煞車墊及飛輪之間施加的力量可能小於可比擬的摩擦煞車所獨立需要的力量。換言之，在給定的時間內，當摩擦煞車與渦流煞車結合時，停止飛輪所需要從使用者輸入的力量可能小於當摩擦煞車未與渦流煞車結合時的力量。
在本發明的一個實施例中，控制機構包括摩擦煞車組件。摩擦煞車組件包括推桿及連接到推桿的摩擦墊。控制機構還包括磁性阻力組件。磁性阻力組件包括可旋轉套筒、與可旋轉套筒接觸的可移動殼體，及設置在可移動殼體內的至少一個磁鐵。控制機構還包括旋鈕，該旋鈕與推桿及可旋轉套筒兩者機械連通。

可旋轉套筒可與鈕旋旋轉地互鎖，使得可旋轉套筒在旋鈕旋轉的時候旋轉。
當旋鈕在第一方向中旋轉時，可旋轉套筒可導致可移動殼體被推向飛輪。
可旋轉套筒可包括套筒螺紋部分。
控制機構可包括蝸輪(worm gear)，其中套筒螺紋部分與蝸輪嚙合(intermeshed)。
控制機構可包括移動感測器，其中該移動感測器附接到蝸輪。
控制機構可包括固定的殼體及殼體螺紋部分，其中套筒螺紋部分與殼體螺紋部分嚙合。
控制機構可進一步包括螺紋移動器，該螺紋移動器與套筒螺紋部分嚙合，其中螺紋移動器與可移動殼體接觸。
在本發明的一個實施例中，運動裝置包括曲柄組件。曲柄組件包括踏板、連接到踏板的踏板臂，及連接到踏板臂的飛輪。運動裝置還包括摩擦煞車組件。摩擦煞車組件包括推桿及連接到推桿的摩擦墊。摩擦墊靠近飛輪，使得在推桿啟動時，摩擦墊接合飛輪。運動裝置還包括磁性阻力組件。磁性阻力組件包括可旋轉套筒、與可旋轉套筒機械連通的可移動殼體，及設置在可移動殼體內的至少一個磁鐵。可移動殼體靠近飛輪，且旋鈕與推桿及可旋轉套筒兩者機械連通。
運動裝置可包括返回彈簧，該返回彈簧與推桿連通。
旋鈕可與推桿旋轉地隔離。
套筒可包括至少一個栓槽，該栓槽與旋鈕的內表面互鎖，並允許旋鈕相對於套筒的軸向運動。
可旋轉套筒可與鈕旋旋轉地互鎖，使得可旋轉套筒在旋鈕旋轉的時候旋轉。
當旋鈕在第一方向中旋轉時，可旋轉套筒可導致可移動殼體在軸向方向中移動。
可旋轉套筒可包括套筒螺紋部分。
當旋鈕旋轉時，可移動殼體樞轉。
在本發明的一個實施例中，運動裝置包括曲柄組件。曲柄組件包括踏板，該踏板連接到踏板臂，及連接到踏板臂的飛輪。運動裝置還包括摩擦煞車組件。摩擦煞車組件包括推桿及連接到推桿的摩擦墊。摩擦墊也靠近飛輪，使得在推桿啟動時，摩擦墊接合飛輪。運動裝置還包括磁性阻力組件。磁性阻力組件包括可旋轉套筒、螺紋移動器，該螺紋移動器螺旋地連接到可旋轉套筒的端部、及可移動殼體，該可移動殼體與螺紋移動器接觸。套筒包括至少一個栓槽，該栓槽與旋鈕的內表面互鎖，並允許旋鈕相對於套筒的軸向移動。可旋轉套筒可與鈕旋旋轉地互鎖，使得可旋轉套筒在旋鈕旋轉的時候旋轉。當旋鈕在第一方向中旋轉時，可旋轉套筒在軸向方向中推動螺紋移動器，其中在第一方向中，螺紋移動器推動可移動殼體。至少一個磁鐵設置在可移動殼體內。可移動殼體靠近飛輪，且旋鈕是與推桿及可旋轉套筒兩者機械連通。旋鈕是旋轉地與推桿隔離。返回彈簧與推桿連通。

圖2描繪控制機構200的範例。在此範例中，旋鈕202可移動地連接到固定式自行車的框架構件。旋鈕202連接到推動桿及其他跨越框架構件的橫截面厚度的組件。在此範例中，旋鈕202的移動可控制及/或影響與飛輪208相關連的參數，該飛輪位於框架構件的下方。例如，摩擦墊210被連接到推桿。在旋鈕202被向內推向框架構件的該等情況中，摩擦墊210朝向飛輪208移動。在旋鈕202被推得足夠向內的該等情況中，摩擦墊210也朝著飛輪208被推得夠遠，以接合飛輪208的周圍。當摩擦墊210靠到了飛輪208的周圍接合，摩擦墊210抵抗飛輪的移動，從而影響到飛輪208的旋轉速度。
旋鈕202也可被旋轉來獨立地影響飛輪208的磁性阻力。可移動殼體212位於框架構件的下方。至少一個磁鐵位於可移動殼體212的內部。磁鐵經定制以施加磁通(magnetic flux)至飛輪208，此舉增加了旋轉飛輪208所需要的能量量。當可移動殼體212被移動遠離飛輪208時，飛輪208所感受到的磁通量減少，降低了旋轉飛輪所需要的能量量。反之，隨著可移動殼體212移動靠近飛輪208(且因此磁鐵移動靠近飛輪)，移動飛輪208所需要的能量量增加。
可移動殼體212可藉由旋轉旋鈕202來移動靠近或遠離飛輪208。返回彈簧216可在控制機構不推靠可移動殼體的時候，在可移動殼體上施加向上的力量。此外，感測器214可用來判定控制機構的內部元件的位置。控制機構200的內部元件在下方連同後續的圖式更詳細地描述。
圖3描繪了控制機構300的範例的剖面圖。在此範例中，控制機構300包括摩擦煞車組件302及磁性阻力組件304。旋鈕306是與摩擦煞車組件302及磁性阻力組件304兩者機械連通。
摩擦煞車組件302包括推桿308，及連接到推桿308的摩擦墊310。旋鈕306可在第一推桿端312被連接到推桿308。推桿308還包括連接到摩擦墊310的第二推桿端314。旋鈕306可在與推桿308同軸的方向中移動，且因此包括多個位置。在第一軸向位置中，旋鈕306被間隔開來，並從第一推桿端312移除一段距離。然而，在第二軸向位置中，旋鈕306接觸第一推桿端312，並對推桿308施加軸向力量，此舉使得摩擦墊310移動到飛輪316中。
磁性阻力組件304包括可旋轉套筒318、與可旋轉套筒318接觸的可移動殼體320，及設置在可移動殼體320內的至少一個磁鐵322。旋鈕306栓槽式地與可旋轉套筒318固定，使得旋鈕306及可旋轉套筒318能相對於彼此軸向移動，但卻是彼此旋轉地互鎖。因此，當旋鈕306旋轉時，可旋轉套筒318也旋轉。可旋轉套筒318與固定式殼體324螺旋結合。可旋轉套筒318包括套筒螺紋部分325，該套筒螺紋部分與感測器327連通。
可旋轉套筒318具有內孔326，該內孔由套筒的內表面所定義。推桿308沿著內孔326的長度而部分地設置在內孔326內。由此，推桿308的長度穿過框架構件329與可旋轉套筒318。
在此範例中，旋鈕306是在初始位置中，且因此摩擦墊310處於與飛輪316隔開的縮回位置中，使得摩擦墊310及飛輪316之間沒有接觸。在此情況中，摩擦墊310不對飛輪316施加摩擦力或者在飛輪316的旋轉上施加機械性影響。返回彈簧330定位在腔室內，該腔室定義在旋鈕400的下側328中，且該返回彈簧連接到環形面，該環形面連接到可旋轉套筒318。在向下推力不存在的情況中，返回彈簧330將旋鈕306推高到初始位置。
螺紋移動器350被附接到可旋轉套筒318的遠端。螺紋移動器350與可旋轉套筒318的外側上的遠端螺紋部分嚙合。隨著可旋轉套筒移動，螺紋移動器350在第一軸向方向或第二軸向方向任一者中移動。在軸向方向的其中一者中，螺紋移動器可朝向飛輪移動，且在另一個軸向方向中，螺紋移動器可遠離飛輪移動。螺紋移動器350可與包含磁鐵的可移動殼體的表面接觸。作為結果，隨著螺紋移動器350移動，可移動殼體也可移動朝向或遠離飛輪。
圖4描繪旋鈕400被推向框架構件的範例。在此範例中，旋鈕的底側403壓縮返回彈簧404，且推桿406被推向飛輪。因此，推桿406將摩擦墊推向飛輪，且當推得足夠遠時，摩擦墊與飛輪直接接觸，並對飛輪施加抵抗飛輪旋轉的摩擦力。
旋鈕400被栓槽固定到可旋轉套筒408。隨著推桿406與旋鈕400的軸向移動而移動，推桿406穿過套筒的內孔。然而，可旋轉套筒並不與旋鈕400的軸向移動而移動。反而，旋鈕400沿著栓槽而軸向移動，該栓槽使得旋鈕400及可旋轉套筒408互鎖。在一些情況中，推桿406是旋轉地獨立於旋鈕400。在此範例中，旋鈕400的底側403可能不與推桿406實體連接，直到旋鈕400被推入推桿406中。在初始位置中，間隙可能存在於旋鈕的底側403及推桿之間。因此，當旋鈕400旋轉時，推桿406可相對於旋鈕400而保持固定。在其他範例中，推桿406可旋轉地連接到旋鈕的底側403。在此範例中，隨著旋鈕400繞著推桿406旋轉，推桿406也相對於旋鈕400保持固定。
當旋鈕400被壓下時，推桿406將摩擦墊410推到飛輪416中以減緩或阻止飛輪416的移動。然而，當推桿406軸向移動時，在推桿406的遠端上的螺紋移動器450的位置不會移動。因此，螺紋移動器所推動的可移動殼體的表面452不會因為推桿406的軸向移動而移動。
圖5是控制機構500的範例的剖面圖。在此範例中，旋鈕502在第一旋轉方向中旋轉。旋鈕502透過栓槽連接而連接到可旋轉套筒504。因此，隨著旋鈕502旋轉，可旋轉套筒504跟著旋鈕502旋轉。
在此範例中，推桿501設置在可旋轉套筒504內。如上方所述，當控制機構的旋鈕推向框架構件503時，推桿501可獨立於可旋轉套筒504而移動。在這些情況中，摩擦墊505可被推入飛輪507，而不影響包含磁鐵509的可移動殼體518的位置。可旋轉套筒504被設置在固定式殼體506內。可旋轉套筒504的螺紋部分508是相鄰於固定式殼體506中所定義的開口510。蝸輪512連接到螺紋部分508，且感測器514連接到蝸輪512，該蝸輪量測可旋轉套筒504的位置及/或移動。
螺紋移動器550隨著可旋轉套筒504的旋轉而在軸向方向中移動。當旋鈕旋轉，使得螺紋移動器550在向上的軸向方向中移動時，螺紋移動器550將可移動殼體518的表面552拉遠。彈簧516在可移動殼體518上施加向上的力量，使得可移動殼體518隨著螺紋移動器550縮回而向上移動。可移動殼體518以樞軸520而支撐在第一側上。彈簧516將可移動殼體518連接到框架構件，以在螺紋移動器550不在可移動殼體518上施加軸向力量時，將可移動殼體518返回到向上位置。作為結果，可移動殼體518隨著旋鈕520在另一個方向中旋轉而樞轉遠離飛輪507。
圖6描繪控制機構600的範例。當旋鈕601旋轉時，旋鈕601及可旋轉套筒604的栓槽互鎖，以造成可旋轉套筒604跟著旋鈕601旋轉。在可旋轉套筒604的遠端中的螺紋部分603造成螺紋移動器650在軸向方向中轉移。在旋鈕601所旋轉的方向造成螺紋移動器650在向下的軸向方向中移動的情況中，螺紋移動器650推靠可移動殼體622的表面652，使得可移動殼體622朝向飛輪移動。在此範例中，蝸輪616是與可旋轉套筒604機械連通，並將感測器618連接到可旋轉套筒604，以判定可旋轉套筒604的位置。
返回彈簧620被連接到框架構件。可移動殼體622可用第一端626上的樞軸桿624、與可移動殼體的第二端630中所定義的凹槽相交的凸部，及在返回彈簧620所支撐。同時，推桿602及摩擦墊606的軸向位置不會被可旋轉套筒604的旋轉、螺紋移動器650的移動，及可移動殼體622的移動所影響。 發明的概述
一般而言，在此揭示的發明可提供運動裝置，該運動裝置具有控制機構，該控制機構調整運動裝置的至少一些參數。運動裝置可為固定式自行車。在此範例中，固定式自行車可包括曲柄組件，該曲柄組件具有第一踏板及第二踏板，該等第一踏板及第二踏板分別透過第一曲柄臂及第二曲柄臂而連接到阻力機構。使用者可藉由坐在併入至固定式自行車的座椅而將他或她自己定位在踏板上。使用者也可在使用運動機的時候使用握把。控制台也可併入到固定式自行車中。控制台可追蹤資訊，例如使用者在他或她的訓練期間所估計燃燒的卡路里量、固定式自行車的飛輪的旋轉速度、由飛輪行走的距離、施加至飛輪的阻力、使用者的生理參數、另一種類型的資訊，或其組合。
控制機構可包括摩擦煞車組件及磁性阻力組件。摩擦煞車組件及磁性阻力組件兩者可透過單一個旋鈕而由使用者所使用。旋鈕可連接到位於固定式殼體中的元件，該固定式殼體併入到固定式自行車的框架構件中。框架構件可經定位以相鄰於飛輪。旋鈕可經定位以在使用者操作固定式自行車期間，使得旋鈕方便使用者伸到。
在一些範例中，當使用者將旋鈕向內推向框架構件及/或朝向飛輪時，控制機構停止飛輪的旋轉或防止飛輪的旋轉。此外，在一些範例中，當使用者旋轉旋鈕時，施加到飛輪的磁性阻力被調整。停止飛輪及調整磁性阻力是兩個不相互影響的獨立操作。例如，當磁性阻力被旋轉旋鈕所調整時，控制機構的摩擦墊不會被採用。類似地，當控制機構的緊急停止功能（亦即摩擦墊）是透過將旋鈕向內推而採用時，施加到飛輪的磁性阻力不改變。因此，緊急停止功能及磁性阻力特徵是彼此獨立的。
摩擦煞車組件可包括推桿及連接到推桿的摩擦墊。推桿可設置在可旋轉套筒的內孔中，該可旋轉套筒主要用於控制機構的磁性阻力特徵。推桿具有第一端及第二端，該第一端經定位以相鄰於旋鈕的下側，該第二端連接到摩擦墊。摩擦墊可經定位以相鄰於飛輪。
旋鈕可具有允許飛輪移動的第一初始位置，及造成飛輪被鎖定到位的第二按壓位置。當旋鈕處於第一初始位置時，旋鈕的底側被壓縮彈簧向上推促 。在此狀況中，彈簧可將底側推得夠遠，使得推桿及旋鈕的底面之間沒有接觸。在這些狀況中，推桿不受旋鈕的旋轉移動所影響。因此，使用者可旋轉旋鈕而不影響推桿。在替代範例中，推桿可連接到旋鈕的下側，但此連接允許推桿與旋鈕旋轉地隔離。
當旋鈕向內推向框架構件及/或飛輪時，旋鈕的下側接觸推桿，並在軸向方向中推動推桿。在一些範例中，大部分的推桿設置在可旋轉套筒內，且隨著旋鈕在軸向方向中推動推桿，推桿沿著可旋轉套筒的內孔的長度移動。連接到推桿的另一端的摩擦墊隨著旋鈕被向推而移動靠近飛輪。在一些範例中，旋鈕推得夠遠，使得摩擦墊接觸飛輪。當使用者施加足夠的力量來向內推動旋鈕時，摩擦墊可由足以防止飛輪移動的力量而被推入飛輪中。
摩擦墊可用樞軸連接而連接到推桿。樞軸連接允許摩擦墊調整其角度，以與飛輪的周圍完全接觸。在一些範例中，摩擦墊具有弧形表面，該弧形表面與飛輪的輪廓相匹配。當摩擦墊與飛輪的周圍接合，摩擦墊及飛輪之間可產生摩擦，該摩擦至少減慢了飛輪的動態。如果在旋鈕上的力量是足夠的，則摩擦墊以足以防止飛輪進一步旋轉運動的力量而接觸飛輪的周圍。
控制機構還包括獨立磁性阻力組件，該獨立磁性阻力組件也由旋鈕所控制。磁性阻力組件包括可旋轉套筒、與可旋轉套筒接觸的可移動殼體，及至少一個磁鐵，該磁鐵設置在可移動殼體內。
在旋鈕處於初始位置時，推桿不接觸旋鈕的底側的一些範例中，旋鈕可在旋鈕處於初始位置期間與可旋轉套筒接觸。事實上，旋鈕也可無關於旋鈕的軸向位置而與可旋轉套筒接觸。例如，旋鈕可透過栓槽連接而連接到可旋轉套筒。此栓槽連接可允許旋鈕與可旋轉套筒旋轉地互鎖，而在同時能夠沿著栓槽的長度而相對於可旋轉套筒滑動。因此，當旋鈕向內推時，旋鈕仍可能是旋轉地連接到可旋轉套筒。任何合適類型的栓槽連接可根據在此描述的原理來使用。例如，栓槽式連接的非窮舉列表可包括：平行鍵栓槽連接、漸伸式(involute)栓槽連接、冠形栓槽連接、螺旋栓槽連接、球形栓槽連接，另一類型的栓槽連接，或其組合。
因此，隨著旋鈕旋轉，可旋轉套筒也會旋轉。在一些範例中，可旋轉套筒所具有的長度大約是固定式殼體的長度。可旋轉套筒可具有外表面，該外表面具有與固定式殼體的內表面產生微小摩擦的特性。在一些範例中，可旋轉套筒是以旋轉軸承而中心定位在固定式殼體內。旋轉軸承隨著可旋轉套筒旋轉而減少磨擦。此外，旋轉軸承可將可旋轉套筒的外表面間隔遠離固定式殼體的內表面，此舉防止了彼此之間發展摩擦。
推桿也可從可旋轉套筒的旋轉絕緣，該絕緣是透過可旋轉套筒的低摩擦內表面及推桿的外側上的低摩擦表面。在其他範例中，旋轉軸承，類似描述於可旋轉套筒的外側與固定式殼體的內側之間的旋轉軸承，可用來減少及/或消除推桿及可旋轉套筒之間的摩擦。此外，在一些範例中，潤滑劑，例如油脂或油，可被用來減少可旋轉套筒及固定式殼體及/或推桿之間的摩擦。雖然該等範例已參照用於減少及/或消除與可旋轉套筒接觸的元件之間的摩擦的具體機構而描述，但任何用於減少摩擦的合適機構可根據本揭示內容中所描述的原理而使用。
在一些範例中，推桿可具有比固定式殼體內的可旋轉套筒更大的長度。在此範例中，推桿可接觸固定式殼體的內表面。在此類情況中，推桿可栓槽固定到固定式殼體，以防止推桿隨著可旋轉套筒旋轉。
在又其他的範例中，推桿可隨著可旋轉套筒旋轉。在這種情況中，推桿可旋轉連接到摩擦墊，使得摩擦墊不與推桿及/或可旋轉套筒旋轉。換言之，摩擦墊不會在旋鈕旋轉時旋轉及/或移動。
在一些情況中，可旋轉套筒包括螺紋部分。在這些情況中，固定式殼體可包括開口，該開口將螺紋部分暴露於固定式殼體的外部。此螺紋部分可連接到固定式殼體外部的元件，使得可旋轉套筒的旋轉移動可被用來致動運動裝置的元件。
在一些情況中，蝸輪部分地設置在開口中，使得蝸輪是與可旋轉套筒的螺紋部分連通。蝸輪可被連接到感測器。在該等範例中，感測器可被用於判定可旋轉套筒的精確位置。由於可移動殼體的位置可由可旋轉套筒的移動來判定，故感測器可被用於判定可移動殼體的位置。在可移動殼體包括影響施加到飛輪的磁性阻力的磁鐵在其他情況中，感測器的讀數可被用來判定或過濾顯示在運動裝置的控制台中的阻力值。雖然上述範例是以用於判定控制台中顯示的阻力值的特定機構而描述，但任何用於判定阻力值的合適機構皆可根據在此描述的原理所使用。例如，阻力值可透過負載單元感測器、應變計(strain gauge)、壓電裝置、磁性感測器、另一類型的機構，或其組合來判定。
可旋轉套筒還可包括另一個螺紋部分，該另一個螺紋部分位於可旋轉套筒的遠端上。螺紋移動器可附接到此遠端螺紋部分，使得螺紋移動器隨著可旋轉套筒旋轉而軸向地移動。因此，當可旋轉套筒在第一方向中旋轉時，螺紋移動器可移出固定式殼體的遠端，且當可旋轉套筒在第二方向中移動時，螺紋移動器可縮回到固定式殼體中。當螺紋移動器移出固定式殼體時，螺紋移動器可推靠著可移動殼體的表面。因此，隨著螺紋移動器移出固定式殼體，螺紋移動器可造成可移動殼體朝向飛輪移動。返回彈簧可在向上的方向中推促可移動殼體。當可移動殼體以螺紋移動器推動時，來自返回彈簧的力量可被克服，且可移動殼體朝向飛輪移動。然而，當螺紋移動器從螺紋殼體移開時，來自返回彈簧的力量可造成可移動殼體在向上的方向中移動，使得可移動殼體樞轉離開飛輪。
在替代範例中，載體被連接到蝸輪，其中當可旋轉套筒旋轉時，蝸輪在軸向方向中移動。在該等範例中，載體可連接到連接件，該連接件與可移動殼體連通。連接件可造成可移動殼體基於載體的移動而移動。因此，當旋鈕在第一旋轉方向中旋轉時，可旋轉套筒類似地在第一旋轉方向中移動，此舉造成載體在第一軸向方向中移動，並造成可移動殼體也隨著載體移動。類似地，隨著旋鈕在第二旋轉方向中旋轉，可移動殼體隨著載體在第二方向中移動。
載體及可移動殼體之間的任何合適類型的連接件可根據本揭示內容描述的原理所使用。例如，連接件可以是彈簧。彈簧的每個端部可包括鉤子。在彈簧的第一端上的第一鉤子可閂扣到載體中的凸部或開口上。類似地，在彈簧的第二端上的第二鉤子可閂扣到可移動殼體中的凸部或開口上。在其他範例中，剛性桿可將載體連接到可移動殼體。在此範例中，剛性桿可在剛性桿的第一端上包括連接到載體的第一樞軸，並在剛性桿的第二端上包括連接到可移動殼體的第二樞軸。
在一些情況中，可移動殼體在第一側上被樞軸支撐，並在第二側上被連接到連接件。因此，隨著連接件基於可旋轉套筒的旋轉而在軸向方向中移動，可移動殼體在軸向方向的大致方向中樞轉。讓可移動殼體朝向及遠離飛輪樞轉的一項優點是，可移動殼體的重量是至少部分地由支撐樞軸桿的固定式結構所支撐。
可移動殼體可包括複數個磁鐵，該等磁鐵經定位以在飛輪上施加磁性影響。隨著磁鐵愈接近飛輪，磁鐵對飛輪施加更大的磁力，此舉造成旋轉飛輪更為困難。隨著磁鐵移動遠離飛輪，旋轉飛輪需要較少的能量。因此，當旋鈕在第一方向中旋轉時，可移動殼體可被移動靠近飛輪，從而增加飛輪上的磁性阻力。類似地，當旋鈕在第二方向旋轉時，可移動殼體可遠離飛輪，以降低抵抗飛輪的磁性阻力。
在一些情況中，可移動殼體只包括單一個磁鐵。在其他範例中，可移動殼體包括一個以上的磁鐵。在一個具體實施例中，可移動殼體包括凹槽，該凹槽具有第一槽壁及第二槽壁。隨著可移動殼體被引導靠近飛輪，凹槽圍繞飛輪的邊緣。在此情況中，第一槽壁及第二槽壁與飛輪的邊緣重疊。磁鐵可被放置在第一槽壁及第二槽壁中，使得磁鐵也與飛輪的邊緣重疊。在此範例中，磁鐵可將磁性阻力施加到飛輪的兩側中，而不僅僅是施加到飛輪的周圍上。然而，在其他範例中，磁鐵僅將阻力施加到飛輪的周圍、僅施加到飛輪的一側、僅施加到飛輪的另一部分，或其組合。
雖然以上範例已經用特定類型的旋鈕描述，但任何合適類型的旋鈕可根據本揭示內容描述的原理所使用。例如，旋鈕可包括大致圓柱形的形狀、大致球根形的形狀、大致正方形的形狀、大致三角形的形狀、大致球形的形狀、不對稱的形狀、另一種類型的形狀，或其組合。進一步而言，以上範例已經參照特定類型的返回機構描述，該等返回機構用於將旋鈕返回到初始位置。然而，任何合適的返回機構可根據在此描述的原理所使用。例如，返回機構可包括壓縮彈簧機構、張力彈簧機構、波形彈簧機構、液壓機構、氣動機構、另一種類型的機構，或其組合。
雖然以上範例已經以具有特定類型的阻力機構的固定式自行車描述，但任何合適類型的固定式自行車可根據本揭示內容描述的原理所使用。例如，固定式自行車可包括磁性阻力機構、氣動阻力機構、液壓阻力機構、齒輪型阻力機構、一對煞車墊、張力元件、風扇葉片、另一種類型的阻力機構，或其組合。雖然以上範例已經參照固定式自行車描述，但在此描述的原理可被併入其他類型的運動或娛樂設備。例如，在此描述的原理可被併入橢圓運動機、槳船、獨輪車、三輪車、步進機、其他類型的腳操作裝置，或其組合。
