Description

運動器材的彈性調整結構
本新型是一種彈性調整機構,尤其是指一種搭配運動器材構型以及調節座,使訓練的阻力強度可供調整之運動器材的彈性調整結構。
因應都會地區的運動空間不足問題,健身房除了早期僅有的重力訓練器材以外,逐步增加了專為空間受限而設計的室內運動器材,例如跑步機或是近期的健身車與飛輪。
其中,採用坐姿運動的健身車與飛輪可以空出雙手,因此已有運動用品業者開發出裝有彈性拉力繩的機型,提供無暇長時間運動的使用者一種更有效率、多部位的運動選擇。
然而,受限於上述這些運動器材的主體結構問題,彈性拉力繩在設置時具有一些缺陷,例如:健身車最常見的結構是X形,這種設計方便於收摺後推移收納,但同時也因這樣的形狀,使得佈繩的位置受限,也就是無法跨經收摺的樞紐部位,此使得彈性拉力繩可供選擇的固定 位置大幅減少,不利於設計多種張力負荷,如此一來將使肌力不堪或是遠大於繩體張力負荷的使用者失去訓練意義,從而造成設備閒置的隱性成本。
另一個缺點是健身車的主支架長度有限,在如此狹小的佈線空間下,彈性拉力繩因為長度相對較短而使單位長度的拉伸應變大幅增加,造成繩材在操作過程中的彈性疲乏加速發生,進而導致耗材汰換率提高。
此外,除了上述的彈性拉力繩設置缺點以外,習知技術遭遇的另一個問題為:繩體的固定位置總是不變。根據虎克定律,彈性彈力繩的復位阻力與拉伸量呈正比,此意味隨著使用者的肌力提升,但卻沒有無限的臂長以繼續拉長繩體的情況下,訓練效果會因阻力無法提升而逐漸遞減至零。雖然可能透過即時更換較短、較粗的彈性拉力繩來繼續提高阻力,但對於提供運動器材給不同大眾使用者的健身房而言,上述習知技術可說過於麻煩而不具使用便利性。
為解決習知技術所遭遇的這些問題,本新型提出一種運動器材的彈性調整結構,其與運動器材的結構彼此配合而加以擴充彈性體(例如:彈性拉力繩)的佈設範圍,且彈性體更可以依據端點的固定位置來進一步改變預設之初始拉伸量,藉此令運動器材能發揮適用於大眾使用者的訓練實益。
依據本新型之一實施方式,提供一種運動器材的彈性調整結構,包含一本體、一交錯架、一調節座、一定位座、一彈性體以及一施力件。
本體構成運動器材的主架構,作用係穩定支撐於地面。交錯架具有一前伸段以及一中段,中段又具有一樞接部樞設於前述本體上,使交錯架與本體形成交錯結構,同時令前伸段由本體向外延伸,且前伸段設置有一延伸座可供物體通過。此外,交錯架上設置有複數個位置相異的固定部,用於搭配其他元件組裝固定。
調節座組接於上述任意的一個固定部上。定位座設於交錯架上。彈性體具有彈性而可以伸縮,例如彈力繩即為一典型實施例,但此處不限制彈性體的態樣之選擇。彈性體通過前述的延伸座以及調節座,而其中一端設置在定位座上,使彈性體一端被間接固定在交錯架上。
施力件連接前述彈性體之另一端,以供使用者往復拉伸操作。前述的調節座可選擇地組接於不同位置的固定部時,由於調節座與延伸座的距離有所增減,故此段的彈性體也隨之產生拉伸量變化。
由上述的實施方式可知,當使用者操作運動器材時,藉由改變調節座的安裝位置,可使彈性體的彈力產生變化,進而可以設定適合的臂力訓練強度,解決同一運動器材的強度變化有限甚至固定之泛用度低的問題。
而在此實施方式架構下,交錯架可以額外包含由前述中段向後延伸之一後伸段,而上述的後伸段即係用 於提供前述那些位置相異的固定部設置。考量彈性體的佈設條件,前述的本體可以設置成局部中空以供彈性體通過,如此一來,彈性體可以遍佈在交錯架的各段,再搭配前述的調節座,令運動器材的阻力設計更加靈活。
在其他可行的實施方式中,前述的定位座也可以可以透過樞接部樞裝在交錯架上,藉以固定彈性體的前述端。
此外,為配合彈力隨時調整的需求特性,調節座可以由形狀相互配合的兩個組合體組合而成,如此可方便調節座改變位置或是從運動器材上拆除。在本實施方式中,兩個組合體可分別位於交錯架的兩側,兩者相互夾掣而彼此套接,並且配合交錯架的形狀而與各個位置的固定部相互固定。
舉例來說,兩組合體可以在交錯架前後兩側彼此鎖合,並且在各個固定部開設栓孔,待調節座調整至適當位置後,以栓接的方式和前述栓孔固定,如此即可完成調節座的安裝。當然,上述的安裝方式僅為本實施方式的一種基本示例,依據運動器材或是佈線條件的改變,調節座、交錯架以及固定部之間的組裝形式可以自由調整,並不受以上限制。
再者,上述的調節座可以包含一滑輪,彈性體在通過調節座時,實際上為相對於調節座滑移在滑輪上,設置滑輪的好處在於可以大幅度地減少彈性體不必要的磨損,並且二度延長彈性體的佈設區間。
例如:使彈性體以滑輪為轉折點來改變其方向,如此一來,彈性體和滑輪可形成大出力、小形變的操作模式,並提升訓練成效。
藉此,本實施方式之運動器材的彈性調整結構不僅可以調整多種彈力強度,更可以透過以上方式提供更進多樣化的阻力選擇,有益於增加運動器材的適用對象。
依據本新型之另一實施方式,提供一種運動器材的彈性調整結構,包含一本體、一交錯架、一調節座、一彈性體以及一施力件。
本體構成運動器材的主架構並支撐於地面。交錯架具有一前伸段以及一中段,中段連接本體,並同時使前伸段由本體向外延伸,且前伸段設置有一延伸座可供物體通過。此外,交錯架上設置有複數個位置相異的固定部。
調節座組接於上述任意的一個固定部上。施力件連接前述彈性體之另一端,以供使用者往復拉伸操作。
本實施方式與前一實施方式的主要差異在於:彈性體通過延伸座後直接一端設置在調節座上。淺白地說,前一實施方式的彈性體係先通過延伸座與調節座後,再一端設置於固定的定位座上,並藉由中介的調節座來改變彈性體的佈設路徑;因此,改變上述的實施方式,此處亦可以省略定位座、直接將調節座設計為彈性體的固定端,而調節座則可安裝於不同位置的固定部,如此同樣能改變彈性體的拉伸量,達成調整彈力強度的功效。
當然,前述的調節座仍可由二組合體互相組合而成,並藉由夾掣套接的方式固定在交錯架上。此外,在一可選擇的實施例中,定位座同樣可以在本實施方式中加以實施,例如交錯架上可以設置定位座,並且令彈性體通過定位座,調節座則繞過定位座後安裝於固定部。
結合此處所述的定位座安裝方式,交錯架可以額外包含由前述中段向後延伸之一後伸段,而定位座穿置在後伸段內,如此不但節省額外裝設定位座的空間,也同時提供了彈性體穿至後伸段另一側的通道。且在此架構下,本體同樣可形成局部中空以供彈性體通過。
另外,上述的定位座也可以包含一樞件,一種可行的實施例為:定位座利用樞件設置在交錯架的末端(例如後伸段),而彈性體藉由樞件(例如選用滑輪)而相對於定位座滑移,同樣可利用彈性體方向改變的原理來增加佈線長度。
依據本新型之又一實施方式,提供一種運動器材的彈性調整結構,包含一本體、一交錯架、一調節座、一定位座、一彈性體以及一施力件。
本實施方式的主要技術特徵與前述另一實施方式大致相同,故此處不再重覆贅述實施細節。本實施方式與前述另一實施方式的主要差異在於調節座具有至少一活動件,而活動件又凸出一抵掣部,用以可選擇地組接於任一固定部上。
此外,雖然本實施方式的彈性體係採用與第一實施方式相同的固定形式,即彈性體的一端固定於定位座上,但本實施方式主要係針對調節座之進一步改良,再透過以上述及的另一實施方式可知,本實施方式的彈性體也可以採用第二種固定形式,也就是無論有無使用定位座,彈性體可以直接定位在調節座上,同時也不影響各種型態的調節座之設置。
在此實施方式中,配合凸出於活動件的抵掣部,固定部可以開設有孔洞以容納抵掣部伸入而彼此固定。而在此處的示例中,活動件可以為樞設在調節座上,並且配合一復位件作動(例如線性彈簧),復位件彈性外張而與活動件互相推抵以進行往復的拮抗運動,如此令抵掣部和固定部彼此固定,而考慮抵掣部和固定部互相抵掣的穩定度,活動件可以成對地對稱設置於任一固定部的兩側,致使調節座不易脫落。
此外,在這樣的實施方式下,調節座仍然可以是兩個組合體組合而成,並據此夾掣套接於交錯架上。
當然,如同前述的其他實施方式所載,本實施方式的定位座除了一體設置在交錯架上,也可以利用一樞接部樞裝於交錯架。同樣的,調節座也可包含一滑輪以供彈性體相對調節座滑移,利用滑輪使彈性體改變方向而在有限的空間中增加佈線區域。而前述的交錯架亦可包含由中段向後延伸之一後伸段,使各個固定部能夠設置於後伸段上,並利用本體所形成的局部中空來提供彈性體通過。
藉由以上介紹的諸多實施方式,本新型可以提供靈活且大幅度的彈性調節機制,不僅能夠良好地適用於廣大的使用者之外,亦不容易為了配合不同使用者的使用需求而發生過度拉扯彈性體、或是阻力太強難以降低的缺點。此外,除了上述優點本身即能避免彈性體耗材快速地汰換之成本問題,本新型所提供的調節座固定機制相對穩定,不容易因為簡單的操作(例如嬰幼兒誤觸)即解除固定,對於運動器材以及人身之安全皆有較佳保護。

第1圖係繪示本新型一實施方式之運動器材的彈性調整結構之左側視圖。請參照第1圖,運動器材的彈性調整結構包含一本體100、一交錯架200、一彈性體300、一施力件400以及一調節座500。
如第1圖所示,本體100立於地面並且作為運動器材之重力的主要支撐。交錯架200包含一樞接部211,而以樞接部211為中心,交錯架200可大致分為中段210、前伸段220以及後伸段230,而樞接部211與本體100樞接,使交錯架200和本體100樞合而成為可折疊的X形架體結構。
在運動器材的前端,前伸段220設置有一延伸座221,而後伸段230則設置有一定位座231,在第1圖的實施方式中,定位座231藉由樞接部211一併樞裝於交錯架200上。當然,圖中示例僅為一種可行的實施態樣,諸如 一體成型或是採用焊接來設置在交錯架200上、以及定位座231可能安裝的位置皆應為本實施方式所能合理涵蓋且自行變化的範圍。
彈性體300跨設並通過前述的延伸座221,在本實施方式中,彈性體300的選用係市面上常見的彈力繩索,在一定的形變範圍內,彈性體300將依據拉伸量而改變其彈性回復力。彈性體300的一端被設置固定於定位座231上,而另一端則與施力件400相連接,以提供使用者往復拉伸運動。
由圖中可知,交錯架200上設有複數個位置相異的固定部240,而若欲獲得較大範圍的佈設空間,可如圖中一般地將固定部240設置於後伸段230上。調節座500同樣受彈性體300跨設並通過,並可選擇地組接於任何一個固定部240上,由於定位座231的位置為固定不動,因此當調節座500與定位座231的距離隨著調節座500的組接位置改變,彈性體300自定位座231至施力件400的行經路徑也就隨之增減,同時使彈性體300的初始彈性回復力改變,藉此調整使用時的阻力強度。
第2A圖係繪示第1圖之運動器材的彈性調整結構之第一視角的立體圖。第2B圖係繪示第1圖之運動器材的彈性調整結構之第二視角的立體圖。請合併參照第2A圖以及第2B圖,詳細說明本實施方式的實施細節,在第2A圖中,彈性體300佈設在交錯架200的背面側,而本體100 在與樞接部211樞接處部位形成局部中空(如第2B圖),彈性體300行經此處時即可通過並且繼續延伸。
在後伸段230的部分,調節座500可以另外包含一滑輪510,滑輪510提供彈性體300通過並通往定位座231。彈性體300於滑輪510處轉折並改變方向。由於繩體可以自由轉向,其張力大小也不受方向問題影響,因此彈性體300可以透過滑輪510的設置獲得再次延長。
第2C圖係繪示第2A圖之運動器材的彈性調整結構之使用狀態示意圖。請配合參照第2C圖,考量定位座231可能採用樞設的方式,彈性體300受外力拉動時可能使定位座231微幅轉動,因此定位座231與彈性體300的固定處也可以採用一樞件231A,例如採用套管以套設在定位座231上。如此一來,定位座231、樞件231A以及彈性體300三者在往復拉伸運動的過程中,樞件231A將按照施力方向微調轉動,使力量傳導可以隨時自動平衡而始終維持直線,以讓使用者的施力操作更加穩定而順暢。
第2D圖係繪示第2A圖之運動器材的彈性調整結構之調節座500的放大部位5分解示意圖。請參照第2D圖,此實施方式為將組合體501、502螺鎖,並利用右方組合體501內側的抵掣部521卡設於固定部240的孔洞上,由於使用者操作運動器材時將彈性體300拉緊,故調節座500於操作中始終被迫緊而抵靠在後伸段230上,而組合體501、502在組合後和後伸段230具有微小的空隙,此供抵掣部521脫離與調整之用,使用者可手握彈性體300並將之 微微下拉以解除抵掣部521的迫緊狀態,待抵掣部521定位於理想的固定部240後,即可鬆開彈性體300而使調節座500重新迫緊。
第3A圖係繪示第2A圖之運動器材的彈性調整結構之另一種調節座500的放大部位5分解示意圖。第3B圖係繪示第2A圖之運動器材的彈性調整結構之又一種調節座500的放大部位5分解示意圖。第3C圖係繪示第2A圖之運動器材的彈性調整結構之再一種調節座500的放大部位5分解示意圖。第3D圖係繪示第2A圖之運動器材的彈性調整結構之再一種調節座500的放大部位5分解示意圖。請參照第3A圖至第3D圖,本新型各種可行之調節座500的實施形式如圖中所示,而其餘之技術特徵與第1圖至第2D圖所介紹之實施方式相同,故不再次說明。
在第3A圖中,固定部240為兩側成對的栓孔,而為了拆卸需要,調節座500可以由二組合體501、502互相組合而成,且兩個組合體501、502的形狀恰好與後伸段230互相配合,使兩者能相互夾掣後套接在交錯架200上,再由夾掣面上的開口與栓孔對齊而栓接在固定部240上。
而如第3B圖所示,調節座500上可以設置能夠旋轉的兩個活動件520,在此實施方式中,兩個活動件520對稱設置在調節座500的兩側,且兩個活動件520皆各自凸出一抵掣部521,抵掣部521之形狀又與孔狀的固定部240相配合。而在抵掣部521的相對端,各活動件520配合一復位件530,復位件530受到活動件520以及調節座500擠壓 而彈性外張,活動件520則受力而產生力矩,使抵掣部521持續地受力而抵掣固定部240。
由第3B圖中可理解的是,當欲調整調節座500位置時,需雙手同時操作兩個活動件520,並且施力抵抗復位件530的彈性外張力,方可使抵掣部521與固定部240脫離。藉此,此種實施方式之調節座500可避免孩童因好奇而輕易解除固定、使調節座500因應彈性體300彈力而意外彈射的危險。
第3C圖揭示為本新型再一種調節座500,本實施方式的兩個組合體501、502可以採用互鎖的方式固定,再額外以T字構件的抵掣部521貫穿插置兩個組合體501、502,並可藉由旋鈕來調整抵掣部521的迫緊度,以決定鬆開或固定調節座500。
如第3D圖所示之再一種調節座500,其同樣包含可以互相鎖合的兩個組合體501、502,此種調節座500的安裝原理如同第3A圖,在組合體501、502鎖合的面上開設與固定部240對齊的拴孔,並於調節座500與後伸段230栓接後,以復位件530頂掣於調節座500與固定部240之間,藉此令調節座500固定。
第4圖係繪示本新型再一實施方式之運動器材的彈性調整結構之調節座500的分解示意圖。請參照第4圖,本實施方式與第2A圖的差異在於彈性體300的一端透過滑輪510直接樞裝設置在調節座500上,也就是彈性體300的端點位置變得可以移動。當然,圖中所示的調節座 500安裝方式僅為示例,參照前述第3A圖至第3D圖的說明可知,本實施方式的調節座500之形式可以任意選擇,並且不會影響本實施方式的正常運作。
在此實施方式中,由於彈性體300的固著條件改由調節座500提供,因此定位座231成為可選配的元件。如同第4圖所示,後伸段230可以沿用對稱的中空支架,或是改以圖中一般的實體支架,並且將定位座231利用其樞件231A穿置在後伸段230內,當然,此處的樞件231A也可以使用滑輪機構取代。此實施方式的好處在於調整彈性體300的拉伸量時較為直觀,且此種設置亦能夠節省空間,定位座231安裝在交錯架200內部的同時,又提供了彈性體300繞行的通道。
由上述各個實施方式所揭露內容,本新型之運動器材的彈性調整結構至少具備以下優點:第一,本新型使用局部中空的本體可供彈性體穿過,克服佈線空間不足的限制,使彈性體的尺寸擁有較多選擇,增加訓練實益。此外,因為彈性體的單位形變量降低,可以有效減緩耗材汰換速度,降低材料添購與人力維護成本。
第二,利用可活動式的調節座,使運動器材可以隨時因應不同使用者的阻力需求隨時調整,除了可避免因使用者肌力進步而使訓練逐漸失效、或是肌力不足卻勉強操作而受傷等問題以外,更重要的是能夠大幅度提升單一運動器材對於廣大使用者的泛用度,對於健身房業者 而言,採用本新型之運動器材的彈性調整結構可以便於管理經營運動器材,省去設施閒置的隱性成本。
第三,本實施方式提供多種可選擇的調節座之實施態樣,可以因應不同使用者的訓練規畫、或是安全考量來選擇合適的調節座,兼顧使用安全以及方便性。
雖然本新型已以實施方式揭露如上,然其並非用以限定本新型,任何熟習此技藝者,在不脫離本新型之精神和範圍內,當可作各種之更動與潤飾,因此本新型之保護範圍當視後附之申請專利範圍所界定者為準。
