Description

無動力跑步機之磁控機構
本創作係有關於一種跑步機，尤指一種無動力跑步機之磁控機構。
按，隨著科技的發展，相對帶動人們的物質生活品質向上提升，在滿足生活基本需求之外，也越來越重視運動以帶來身體健康及身材的保持，但大多數人由於平常生活作息相當緊湊忙碌，等到休假或有空閒想要從事運動時，卻又受限於場地及其他因素而無法順利進行，於是許多人選擇使用跑步機，一般跑步機包括扶手、機架、跑步帶等，該扶手安裝在該機架的前部，該機架的前後兩端分別安裝一前輪組與一後輪組，該跑步帶繞設在該機架的前輪組與後輪組之間，跑者只要踏在跑步帶就可進行跑步練習，使用起來十分方便，而可隨時提供適時之運動，以達到一定之運動量。
目前跑步機主要分為電動跑步機與無動力跑步機兩種，無動力跑步機不具電動機，可省去電動機的成本且可節省能源效率，近年來越來越受到歡迎，並且為使跑者在跑步機上跑步時具有不同阻力，以符合跑著的需求，是以習知無動力跑步機有於前輪組一側裝設一磁控機構，該磁控機構包含：一飛輪及一可調整位置的磁體，使用時透過移動該磁體與該飛輪的相對位置，來調整飛輪的旋轉阻力，進而達到調整跑者在跑步機上跑步時的阻力，以及為了避免跑者在跑步機上停止跑動時，跑步帶因慣性持續滑動，致使跑者不慎滑倒而受傷，於該磁控機構與該前輪組間配合設有一單向傳動裝置，使得動作中的跑步帶可立即停止滑動，以提高跑步機的使用安全性。
惟，該習知無動力跑步機，不僅磁控機構與單向傳動裝置結構複雜，致使跑步機的製造成本增加，並且磁控機構及單向傳動裝置的組裝、拆卸與維修保養均相當麻煩不便，而浪費人力與工時。
本創作人有鑑於習知無動力跑步機具有上述缺點，是以乃思及創作的意念，經多方探討與試作樣品試驗，及多次修正改良後，遂推出本創作。
本創作提供一種無動力跑步機之磁控機構，包含：一跑步機本體，該跑步機本體包括一機架，該機架設有一組裝側，該機架前端安裝一前輪組，該前輪組設有一前軸心，該前軸心延伸至該組裝側；一單向傳動元件，該單向傳動元件固設於該機架之組裝側；及一磁控機構，組設於該機架之組裝側，該磁控機構包括一轉軸、一主動輪、一從動輪、一皮帶、一飛輪及一阻力件及一調整單元，該轉軸組設於該單向傳動元件上，該主動輪套設於該跑步機本體之前輪組的前軸心結合，該從動輪套設於該轉軸上結合，該皮帶繞設於該主動輪與該從動輪之間，而可透過該皮帶使得該主動輪與該從動輪連動，該飛輪套設於該轉軸上結合，該阻力件設有一對板片及複數磁性件，該對板片係平行設置，一端設有一樞接部，利用該樞接部配合一彈性件樞組於該機架之組裝側，使該對板片可利用該樞接部為軸心進行旋擺，並可通過該彈性件使該對板片於未受力狀態時自動回復原位，該複數磁性件係成對地間隔設置在該對板片的相對內側面，該調整單元設有一鋼索線，該鋼索線一端與該阻力件連接，而可由該鋼索線拉動該阻力件之該對板片旋擺。
本創作無動力跑步機之磁控機構之主要目的，在於其結構簡單，跑步機的製造成本降低，並且磁控機構與單向傳動元件的組裝、拆卸與維修保 養均相當方便快速，而可節省人力與工時。

請參閱第一圖、第二圖、第三圖、第四圖及第五圖，本創作無動力跑步機之磁控機構，包含：一跑步機本體10、一單向傳動元件20及一磁控機構30。
該跑步機本體10包括一機架11，該機架11前部組設一扶手(圖中未示)，該機架11設有一組裝側111，該機架11前後兩端分別安裝一前輪組12與一後輪組(圖中未示)，該前輪組12與後輪組之間繞設一跑步帶(圖中未示)，該前輪組12設有一前軸心121，該前軸心121延伸至該組裝側111。
該單向傳動元件20固設於該跑步機本體10機架11之組裝側111，該單向傳動元件20於本實施例為單向軸承。
該磁控機構30組設於該機架11之組裝側111，該磁控機構30包括一轉軸31、一主動輪32、一從動輪33、一皮帶34、一壓迫輪35、一飛輪36、一 阻力件37及一調整單元38，該轉軸31組設於該單向傳動元件20上，該主動輪32中心設有一第一結合孔321，以該第一結合孔321套設於該跑步機本體10之前輪組12的前軸心121一端結合，該從動輪33中心設有一第二結合孔331，以該第二結合孔331套設於該轉軸31上結合，該皮帶34為時規皮帶，繞設於該主動輪32與該從動輪33之間，而可透過該皮帶34使得該主動輪32與該從動輪33連動，該壓迫輪35係設置於該轉軸31一側，用以壓迫該皮帶34，使該皮帶34保持適當的鬆緊度，該飛輪36為鋁合金材質製成之圓片體，中心設有一第三結合孔361，以該結合孔361套設於該轉軸31上結合，該阻力件37設有一對板片371及複數磁性件372，該對板片371係平行設置，一端設置一樞接部3711，利用該樞接部3711配合一彈性件373樞組於該機架11之組裝側111，使該對板片371可利用該樞接部3711為軸心進行旋擺，並可通過該彈性件373的回復彈力使該對板片371具有自動復位功能，該複數磁性件372係成對地間隔設置在該對板片371的相對內面，該磁性件372於本實施例為強力磁鐵，該彈性件373於本實施例為扭力彈簧，該調整單元38設有一鋼索線381，該鋼索線381一端與該阻力件37之該對板片371連接，而可由該鋼索線381拉動該阻力件37之板片371以樞接部3711為軸心旋擺。
當跑者在跑步機上跑步時，如第六圖及第七圖所示，由跑者帶動跑步帶運轉，連動前輪組12與後輪組轉動，使得磁控機構30之主動輪32隨前輪組12之前軸心121轉動，透過皮帶34由主動輪32帶動從動輪33轉動，再由該從動輪33透過轉軸31連動該飛輪36轉動，利用阻力件37的磁性件372和飛輪36產生渦電流形成阻力，並可利用調整單元38之鋼索線381拉動阻力件37之板片371以樞接部3711為軸心旋擺，配合彈性件373使板片371的自動復位功能，來調整 控制阻力的大小，阻力件37的磁性件372與飛輪36愈靠近所產生的阻力愈大，阻力件37的磁性件372與飛輪36愈遠離所產生的阻力愈小，藉由上述方式調節阻力大小來實現跑步機不同運動阻力強度的需求。
再者，由於磁控機構30之轉軸31係組設於單向傳動元件20上，因而當跑者在跑步機上停止跑動時，可藉由單向傳動元件20使跑步機於作動中立即停止，而無殘留之慣性力，避免跑步帶因慣性持續滑動，致使跑者不慎滑倒而受傷，以提高跑步機的使用安全性。
由上述具體實施例之結構，可得到下述之效益：本創作無動力跑步機之磁控機構，其結構簡單，跑步機的製造成本降低，並且磁控機構30與單向傳動元件20的組裝、拆卸與維修保養均相當方便快速，而可節省人力與工時，符合經濟效益。
